Obesity is a major health concern in Hispanic populations. This study evaluated the epidemiology of obesity and associated factors among Hispanics using the data from the 2013-2014 National Health and Nutrition Examination Survey. Among the 1241 participants (20 years of age or older), the prevalence rates were as follows: overweight, 77.1%; obesity, 42.4%; and central obesity, 57.0%. These rates were consistent throughout most age groups. Significantly, more females than males were obese. Higher obesity rates were seen among those with diabetes, high cholesterol, hypertension, heart disease, and arthritis...

BACKGROUND: Timing of surgical intervention for acute ulcerative colitis has not been fully examined during the modern immunotherapy era. Although early surgical intervention is recommended, historical consensus for "early" ranges widely. The purpose of this study was to evaluate outcomes according to timing of urgent surgery for acute ulcerative colitis. METHODS: All non-elective total colectomies in ulcerative colitis patients were identified in the National Inpatient Sample from 2002 to 2014...

Despite much work in recent years, vehicle emissions remain a significant contributor in many areas where air quality standards are under threat. Policy-makers are actively exploring options for next generation vehicle emission control and local fleet management policies, and new monitoring technologies to aid these activities. Therefore, we report here on findings from two separate but complementary blind evaluation studies of one new-to-market real-world monitoring option, HEAT LLC's Emission Detection And Reporting system or EDAR, an above-road open path instrument that uses Differential Absorption LIDAR to provide a highly sensitive and selective measure of passing vehicle emissions...

Scanning tunnelling microscopy (STM), low energy electron diffraction (LEED), ultraviolet and soft X-ray photoelectron spectroscopy (UPS and SXPS) have been used to characterise the formation of a coadsorption phase of TCNQ and K on Ag(111), while the normal incident X-ray standing waves (NIXSW) technique has been used to obtain quantitative structural information. STM and LEED show that an ordered incommensurate phase is formed in which the K atoms are surrounded by four TCNQ molecules in a 'windmill' motif, characteristic of other metal/TCNQ phases, in which the nominal TCNQ : K stoichiometry is 1 : 1...

Background and study aims The Endocuff (ARC Medical Design, Leeds, UK) is a device that, when mounted on the tip of an endoscope, may assist with inspection of a greater surface of the colonic mucosa by pulling backwards, flattening, and stretching the colonic folds as the endoscope is gradually withdrawn. We aimed to compare the adenoma miss rates of Endocuff-assisted colonoscopy with those of conventional colonoscopy. Patients and methods The included patients underwent same-day, back-to-back, (Endocuff-assisted colonoscopy as the index procedure followed by conventional colonoscopy or vice versa, randomly assigned 1:1) colonoscopies, performed by six endoscopists with documented adenoma detection rates > 35 %, in four tertiary endoscopy facilities...

Combinatorial inhibition of effector and feedback pathways is a promising treatment strategy for KRAS mutant cancers. However, the particular pathways that should be targeted to optimize therapeutic responses are unclear. Using CRISPR/Cas9, we systematically mapped the pathways whose inhibition cooperates with drugs targeting the KRAS effectors MEK, ERK, and PI3K. By performing 70 screens in models of KRAS mutant colorectal, lung, ovarian, and pancreas cancers, we uncovered universal and tissue-specific sensitizing combinations involving inhibitors of cell cycle, metabolism, growth signaling, chromatin regulation, and transcription...

Schizotypy is regarded as a trait vulnerability for psychotic disorders, yet alone is insufficient for development of a diagnosable disorder. Additional symptoms and psychological distress are necessary for help seeking and transition from an at risk mental state to a clinical diagnosis. The present study investigated the interaction between trait schizotypy, state auditory verbal hallucination (AVH) predisposition, distress and handedness for the expression of neurological soft signs (NSS), a neurodevelopmental vulnerability factor for psychosis...

AIM: Inhaled hypertonic saline increases mucociliary clearance, improves pulmonary function, and decreases exacerbations in cystic fibrosis (CF) but contributes to the already significant treatment burden of CF. Overnight delivery of inhaled medications via a specially designed nasal cannula-aerosol device (Trans-nasal Pulmonary Aerosol Delivery [tPAD]) is an alternative approach. Here, we test whether overnight inhalation of hypertonic saline via tPAD improves mucociliary clearance and assess the tolerability of the device...

Recent methods for transcriptome-wide N6-methyl-adenosine(m6A) profiling have facilitated investigations into the RNA methylome and established m6A as a dynamic modification that has critical regulatory roles in gene expression and may play a role in human disease. However, bioinformatics resources available for the analysis of m6A sequencing data are still limited. Here, we describe m6aViewer - a cross-platform application for analysis and visualisation of m6A peaks from sequencing data. m6aViewer implements a novel m6A peak-calling algorithm that identifies high-confidence methylated residues with more precision than previously described approaches...

OBJECTIVE: Human Bocavirus (HBoV) was first identified in 2005 and has been shown to be a common cause of respiratory infections and gastroenteritis in children. In a recent study, we found that 10.7% of children with acute respiratory infections (ARI) were infected by HBoV. Genetic characterization of this virus remains unknown in Central Africa, particularly in Cameroon Leeding us to evaluate the molecular characteristics of HBoV strains in Cameroonian children with ARI. RESULTS: Phylogenetic analysis of partial HBoV VP1/2 sequences showed a low level of nucleotide variation and the circulation of HBoV genotype 1 (HBoV-1) only...

UK Biobank is among the world's largest repositories for phenotypic and genotypic information in individuals of European ancestry. We performed a genome-wide association study in UK Biobank testing ∼9 million DNA sequence variants for association with coronary artery disease (4,831 cases and 115,455 controls) and carried out meta-analysis with previously published results. We identified 15 new loci, bringing the total number of loci associated with coronary artery disease to 95 at the time of analysis. Phenome-wide association scanning showed that CCDC92 likely affects coronary artery disease through insulin resistance pathways, whereas experimental analysis suggests that ARHGEF26 influences the transendothelial migration of leukocytes...

Multiple patient-reported outcomes (PROs) are currently being used in multiple sclerosis (MS) but their application is inconsistent and guidance on the appropriateness of each tool is lacking. The objective of our study was to identify MS-specific PROs and systematically to assess the development process and the reliability and validity of various instruments. A systematic literature search was conducted on multiple data sources, including MEDLINE, Embase (using the Ovid platform) and Google Scholar, from 1996 to March 2015...

Amelogenesis imperfecta (AI) is the name given to a heterogeneous group of conditions characterized by inherited developmental enamel defects. AI enamel is abnormally thin, soft, fragile, pitted and/or badly discolored, with poor function and aesthetics, causing patients problems such as early tooth loss, severe embarrassment, eating difficulties, and pain. It was first described separately from diseases of dentine nearly 80 years ago, but the underlying genetic and mechanistic basis of the condition is only now coming to light...

Quantification of T-cell receptor excision circles (TRECs) for newborn screening for SCID has advanced the diagnosis of severe combined immune deficiency (SCID). However, it has led to the identification of infants with T cell lymphopenia without known cause. The clinical characteristics, appropriate laboratory monitoring, and outcomes of patients remain unclear. We performed a retrospective review of clinical and laboratory studies for 26 infants collected from 7 New York State referral centers from 2010 to 2016 with low TRECs (mean, 70copies/μl) and subnormal CD3 counts (mean, 1150/cubicmm)...

PURPOSE: Evidence suggests that homeostatic satiety signalling is enhanced with higher levels of physical activity (PA), with active individuals demonstrating an improved ability to compensate for previous energy intake (EI). However, prior studies lacked objective assessment of both PA level and EI. This study examined the effect of objectively-measured PA level on homeostatic (energy compensation) and hedonic (liking and wanting) responses to high-energy (HEP), low-energy (LEP) and control preloads...

We studied the growth of Ge layers on Au(111) under ultra-high vacuum conditions from the submonolayer regime up to a few layers with Scanning Tunneling Microscopy (STM), Direct Recoiling Spectroscopy (DRS) and Low Energy Electron Diffraction (LEED). Most STM images for the thicker layers are consistent with a commensurate 5 × 8 arrangement. The high surface sensitivity of TOF-DRS allows us to confirm the coexistence of Au and Ge atoms in the top layer for all stages of growth. An estimation of the Au to Ge ratio at the surface of the thick layer gives about 1 Au atom per 2 Ge ones...
