Total, bioaccessible and mobile concentrations of arsenic and fluorine are determined in polluted surface soil within the Comarca Lagunera region using standardized protocols to obtain a full description of the environmental behavior for these elements. The composition of mineral phases associated with them is evaluated with microscopic and spectroscopic techniques. Mineralogical characterizations indicate that ultra-fine particles (<1-5 μm) including mimetite-vanadite (Pb5(AsO4)3Cl, Pb5(AsO4, VO4)3Cl)-like, lead arseniate (Pb3(AsO4)2)-like and complex arsenic-bearing compounds are main arsenic-bearing phases, while fluorite (CaF2) is the only fluorine-bearing phase...

Transporters shuttle molecules across cell membranes by alternating among distinct conformational states. Fundamental questions remain about how transporters transition between states and how such structural rearrangements regulate substrate translocation. Here, we capture the translocation process by crystallography and unguided molecular dynamics simulations, providing an atomic-level description of alternating access transport. Simulations of a SWEET-family transporter initiated from an outward-open, glucose-bound structure reported here spontaneously adopt occluded and inward-open conformations...

Genome sequencing has revolutionized the diagnosis of genetic diseases. Close collaborations between basic scientists and clinical genomicists are now needed to link genetic variants with disease causation. To facilitate such collaborations, we recommend prioritizing clinically relevant genes for functional studies, developing reference variant-phenotype databases, adopting phenotype description standards, and promoting data sharing.

Objective.:  An average of 91 people in the United States die every day from an opioid-related overdose (including prescription opioids and heroin). The direct dispensing of opioids from health care practitioner offices has been linked to opioid-related harms. The objective of this study is to describe the changing nature of the volume of this type of prescribing at the state level. Methods.:  This descriptive study examines the distribution of opioids by practitioners using 1999-2015 Automation of Reports and Consolidated Orders System data...

Background and Aims: Nicotine addiction theory predicts small day to day variability in cigarettes/day (CPD) whereas social learning theory predicts large variability. A description of the variability in CPD over multiple days is not available. Methods: We conducted secondary analyses of two natural history studies with daily smokers - one of smokers not intending to quit, and one of smokers intending to quit sometime in the next 3 months. In the former, smokers recorded their smoking during the day by Ecological Momentary Assessment, using a palm-top computer...

Debates around policies regulating e-cigarette use make it important to obtain an overview of current practice, people's attitudes and correlates of policy support. Aims were to assess (i) current practices for e-cigarette use in homes and workplaces; (ii) characteristics associated with allowing e-cigarette use in the home; and (iii) level of, and characteristics associated with, support for extending smoke-free legislation to include e-cigarettes. Online survey in 2016, n = 11 389 adults in Great Britain...

Background.: In January 2012, Argentina included universal pneumococcal vaccination in the routine childhood vaccination program using a 13-valent pneumococcal conjugate vaccine (PCV13). A 2 + 1 schedule (2 doses in the first year of life and a booster dose at 12 months of age) in children aged <2 years and 2-dose catch-up immunization in children aged 13 to 24 months was administered during the first year of vaccine introduction. The purpose of this study was to assess the burdens of invasive pneumococcal disease (IPD) and/or community-acquired pneumonia (CAP) in hospitalized children younger than 5 years during the first 2 years of the program compared to those in the prevaccination period in our setting...

Objective:  Psychosocial risk screening is an important initial step in delivering evidence-based care. This qualitative descriptive study identified how multidisciplinary pediatric oncology health-care providers perceive psychosocial risk screening to identify factors in uptake and implementation. Methods:  A script guided digitally recorded (transcribed) interviews regarding psychosocial screening and challenges to facilitators of screening. Participants were 15 multidisciplinary staff (physicians, nurses, social workers, psychologists, physician assistant) at nine sites, three using the Psychosocial Assessment Tool© for research and six for clinical care...

Introduction: Smokers are using electronic cigarettes, also known as e-cigarettes, as a cessation aid, despite uncertainty about their efficacy. This report describes the association between use of e-cigarettes before and after cessation treatment and tobacco abstinence at 12 months. It also presents characteristics of e-cigarette users and reasons for use. Methods: A longitudinal observational secondary analysis of self-reported e-cigarette use was conducted among adult Appalachian smokers enrolled in a community-based tobacco dependence treatment trial (n = 217)...

Setting.:  Epidural hematoma rarely complicates interventional spine procedures. While anticoagulant and antiplatelet drugs increase bleeding risk, cessation may precipitate serious thromboembolic events. The Spine Intervention Society (SIS) and American Society of Regional Anesthesia and Pain Medicine (ASRA) put forth guidelines that dissent with regard to management of hemostatically active agents during commonly performed spinal injections. Objective.:  To validate an antiplatelet/anticoagulant management table based on modifications of the SIS 2013 and ASRA 2015 guidelines...

Omics studies of systemic autoimmune diseases (SADs) in general, and SLE in particular, have delivered isolated information from transcriptome, epigenome, genome, cytokine and metabolome analyses. Such analyses have resulted in the identification of disease susceptibility genes and the description of IFN expression signatures, allowing extensive insight into the mechanisms of disease and the development of new therapies. Access to such technologies allows the recognition of patterns of disease at a pathway level, thereby, to reclassify SLE and other SADs and to develop new therapeutics from a personalized perspective...

INTRODUCTION: A large and increasing number of HIV-infected women are conceiving on antiretroviral treatment (ART). While most antiretrovirals are considered safe in pregnancy, monitoring for rare pregnancy and infant adverse outcomes is warranted. METHODS: We conducted a retrospective secondary analysis nested within a clinical trial of infant cotrimoxazole vs. placebo prophylaxis in Botswana (the Mpepu Study). Infants were examined at birth, and at least every 3 months through 18 months of age...

BACKGROUND: In Canada, functional capacity evaluations (FCEs) are commonly administered by several health care professions including kinesiologists. Kinesiologists have been recently regulated as health care professionals in Ontario and we know little about their demographics, the frequency of FCE administration, or the types of FCEs used by this group. OBJECTIVE: The purposes of this study were to identify: 1) the demographic characteristics and FCE education of kinesiology FCE practitioners; 2) the FCE systems most used by these practitioners and 3) the constructs from assessments used to determine functional capacity...

BACKGROUND: Huntington Disease-like 2 (HDL2) is a neurodegenerative disorder similar to Huntington Disease (HD) in its clinical phenotype, genetic characteristics, neuropathology and longitudinal progression. Proposed specific differences include an exclusive African ancestry, lack of eye movement abnormalities, increased Parkinsonism, and acanthocytes in HDL2. OBJECTIVE: The objective was to determine the similarities and differences between HD and HDL2 by establishing the clinical phenotype of HDL2 with the published cases...

The use of compounded bioidentical hormone replacement therapy by menopausal women has become a popular alternative to traditional synthetic conjugated equine estrogen and progestin hormone replacement therapy due to safety concerns raised by recent studies. However, due to the lack of randomized, large-scale trials to evaluate the efficacy and side-effect profile of compounded bioidentical hormone replacement therapy many healthcare providers are reluctant to prescribe such therapy. The purpose of this study was to compare women's menopausal symptom relief and side effects experienced when using compounded bioidentical hormone replacement therapy and traditional hormone replacement therapy...
