Introduction: Prior studies have found heightened negative affect following tobacco abstinence in women compared to men. However, experimental work addressing whether these findings generalize across racial groups is scarce. The current study investigated whether race (Non-Hispanic White vs. Non-Hispanic African American) moderated gender differences in abstinence-induced negative affect and smoking behavior. Methods: Data were collected from 2010 to 2017 from two separate laboratory studies investigating experimentally manipulated tobacco abstinence...

Improving estimates of individuals' dietary intakes is key to obtaining more reliable evidence for diet-health relationships from nutritional cohort studies. One approach to improvement is combining information from different self-report instruments. Previous work evaluated the gains obtained from combining information from a food frequency questionnaire (FFQ) and multiple 24-hour recalls (24HRs), based on assuming that 24HRs provide unbiased measures of individual intakes. Here, we evaluate the same approach of combining instruments, but based on the better assumption that recovery biomarkers provide unbiased measures of individual intakes...

Metabolomics, the study of small molecules involved in cellular processes, offers the potential to reveal insights into the pathophysiology of disease states. Analysis of metabolites by electrospray mass spectrometry is complicated by their structural diversity. Amine, hydroxyl, and carboxylate groups all affect signal responses differently based on their polarity and proton affinity. This heterogeneity of signal response, sensitivity, and resistance to competing ionization complicates metabolite quantitation...

Methicillin-resistant Staphylococcus aureus (MRSA) acquisition in cystic fibrosis (CF) patients confers a worse clinical outcome with increased rate of declined lung function. Telavancin, an approved lipoglycopeptide used to treat infections due to S. aureus has a dual mode of action causing inhibition of the peptidoglycan synthesis and membrane depolarization. CF-associated MRSA infections remain an important problem with no foreseeable decline in prevalence rates. Although telavancin is currently in clinical use for complicated skin infections and hospital-acquired pneumonia, the activity against CF- associated S...

Nowadays, ride-hailing services have been established as a part of the urban transportation. Their arrival has remade the profit structure and resulted in the unbalance of interest in taxi market. Here, we establish the service models of taxis, carpooling, and car-hailing under "Internet +" from the perspective of profit margins, to perform a comparative analysis among the different services. RESULTS: First, Profit margins are generally higher for short trips than for long trips, though empty cruise fee to a certain degree make up for the driver's decreased profit margins...

OBJECTIVE: Low-dose hydrocortisone (LDH) enhances aspects of learning and memory in select populations including patients with PTSD and HIV-infected men. HIV-infected women show impairments in learning and memory, but the cognitive effects of LDH in HIV-infected women are unknown. DESIGN: Double-blind, placebo-controlled, cross-over study examining the time-dependent effects of a single low-dose administration of hydrocortisone (10 mg oral) on cognition in 36 HIV-infected women...

This cross-sectional study used quantitative survey data collected from registered nurses (RNs) who worked as staff nurses in medium-sized (300 beds or less) Korean hospitals. Data from 290 RNs were analyzed to examine the nature and prevalence of staff nurses' work hours, overtime, breaks, and related work conditions. The results showed that staff nurses working in medium-sized Korean hospitals worked 9.6 hours a day on average and had 1.5 breaks daily, including mealtime. The average number of days the nurses skipped a meal due to work during the last month was 6...

The aim of this systematic review was to explore studies regarding association between occupational stress and heart rate variability (HRV) during work. We searched PubMed, Web of Science, Scopus, Cinahl and PsycINFO for peer-reviewed articles published in English between January 2005 and September 2017. A total of 10 articles met the inclusion criteria. The included articles were analyzed in terms of study design, study population, assessment of occupational stress and HRV, and the study limitations. Among the studies there were cross-sectional (n=9) studies and one longitudinal study design...

Objectives The aim of this study was to examine blood concentrations of 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) among indoor, outdoor, permanent and rotating night workers and the association with hours spent outdoors on and off work days. Methods Blood samples were collected from 425 workers (162 indoor, 112 outdoor, 118 rotating night and 33 permanent night workers) throughout all seasons. Serum concentrations of 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) were analyzed by isotope dilution liquid chromatography-tandem mass spectrometry (LC MS/MS) and an automated immune analyzer, respectively...

Precise engineering of nanoparticles with systematically varied properties (size, charge surface properties, targeting ligands, etc.) remains a challenge, limiting the effective optimization of nanoparticles for particular applications. Herein we report a single-step microfluidic combinatorial approach for producing a library of single and dual-ligand liposomes with systematically-varied properties including size, zeta potential, targeting ligand, ligand density, and ligand ratio. A targeting ligand folic acid and a cell penetrating peptide TAT were employed to achieve the optimal synergistic targeting effect...

Jore Hendrikx, Dirk Van Raemdonck, Jacques Pirenne, Steffen Fieuws, Steffen Rex
Transplant procedures are frequently performed outside the regular working hours (after hours). In general surgery, several studies observed worse outcomes for operations performed after hours. The predetermined hypothesis was that patients undergoing transplantation during after hours might suffer from an excess in post-operative mortality and morbidity when compared to patients undergoing transplantations during the regular working hours. A systematic review of the PubMed database identified 11,993 records, of which eleven cohort studies including a total of 287,741 patients investigated the association between the starting time of transplant surgery and postoperative mortality (primary outcome) and/or morbidity (secondary outcome)...

OBJECTIVE: The objective of this study was to evaluate the ability of the BioFire FilmArray Blood Culture Identification (BCID) Panel to rapidly detect pathogens producing late-onset ventilator-associated pneumonia (VAP), a severe infection often produced by Gram negative bacteria. These microorganisms are frequently multidrug resistant (MDR) and typically require broad spectrum empiric treatment. METHODS: In this study, in the context of an international multicenter clinical trial (Magic Bullet), respiratory samples were collected at the time of suspicion of VAP from 165 patients in 32 participating hospitals in Spain, Greece and Italy...

INTRODUCTION: Previous studies have shown that French-speaking family physicians (FSPs) in Ontario are less numerous in areas with high proportions of francophones. The purpose of the current study was to assess whether the degree of concordance between physicians' language of competence and the linguistic profile of the community in which they practise is associated with workload and to explore variations in this relation in rural and northern regions of the province. METHODS: This was a secondary analysis of the 2013 College of Physicians and Surgeons of Ontario Annual Membership Renewal Survey...

Introduction: Knowledge of acute inhalation toxicity potential is important for establishing safe use of chemicals and consumer products. Inhalation toxicity testing and classification procedures currently accepted within worldwide government regulatory systems rely primarily on tests conducted in animals. The goal of the current work was to develop and prevalidate a nonanimal ( in vitro ) test for determining acute inhalation toxicity using the EpiAirway™ in vitro human airway model as a potential alternative for currently accepted animal tests...
