There is mounting scientific evidence showing the importance of innate biological rhythms on disease onset and progression. Perhaps the most important of these is the circadian rhythm, a cycle of oscillations lasting approximately 24 hours. Recent work has shown that circadian rhythms are intrinsically linked to the immune system in a bidirectional fashion, and disruption of these cycles can contribute to changes in pathology and quality of life (including fatigue, mood, and disability). This is particularly true in diseases of the nervous and immune systems...

Background The impact of resident work hours on resident well-being and patient safety has long been a controversial issue. Objectives What has not been considered in resident work hour limitations is whether resident commuting time has any impact on a resident's total work hours or well-being. Methods A self-administered electronic survey was distributed to emergency medicine residents in 2016. Results The survey response was 8% (569/6828). Commuter time was 30 minutes or less in 70%. Two residents reported a commuter time of 76 to 90 minutes and one resident had a commuter time of 91 to 105 minutes...

Use of mobile phones while driving is known to cause crashes with possible fatalities. Different habits of mobile phone use might be distracting forces and display differential impacts on accident risk; the assessment of the relative importance is relevant to implement prevention, mitigation, and control measures. This study aimed to assess the relationship between the use of mobile phones at population level and road crash fatalities in large urban areas. Data on road crashes with fatalities were collected from seven Italian metropolitan areas and matched in time and space with high resolution mobile phone traffic volume data about calls, texts, Internet connections and upload/download data...

Introduction In 2015, the Royal College of Surgeons of England (RCS) commissioned the East Midlands Clinical Network to develop a set of guidelines for the management of paediatric torsion. Two quality measures identified were the provision of surgery locally where possible and 100% of explorations within three hours. We sought to assess the adherence to these quality measures within our referral network. Materials and methods Retrospective data were collected for all paediatric scrotal explorations performed within our centre between January 2014 and July 2016...

This work is concerned with the long-term behavior of environmentally-assisted subcritical cracking of PECVD SiNx barrier films on polyethylene terephthalate (PET) and polyimide (PI) substrates. While environmentally-assisted channel cracking in SiNx has been previously demonstrated, with constant crack growth rates over short periods of time (<1 hour) during which no substrate damage was observed, the present experiments over longer periods reveal a regime where cracking also develops in the polymer substrate...

BACKGROUND: Intentional rounding (IR) is a structured process whereby nurses conduct one to two hourly checks with every patient using a standardised protocol. OBJECTIVE: A realist synthesis of the evidence on IR was undertaken to develop IR programme theories of what works, for whom, in what circumstances and why. METHODS: A three-stage literature search and a stakeholder consultation event was completed. A variety of sources were searched, including AMED, CINAHL, MEDLINE, PsycINFO, HMIC, Google and Google Scholar, for published and unpublished literature...

Background: In keeping with the need to protect the safety and health of workers, the EU Working Time Directive stipulates that a worker's average working time for each 7-day period, including overtime, does not exceed 48 h. It has, however, not been settled whether or not the threshold at 48 working hours a week is low enough to protect against excess mortality from long work weeks. The aim of the present study was to examine all-cause mortality in relation to weekly working hours among employees in the general population of Denmark...

This study aims to describe the prevalence of heavy drinking, high-risk alcohol consumption and associated factors among tobacco farmers. A cross-sectional study was carried out with 2,469 tobacco farmers over 18 years old in 2011. High-risk alcohol consumption was considered the intake of three or more standard doses per day for men or two or more for women. Heavy drinking was considered the intake of four or more standard doses per day for men and three or more for women. Hierarchical multivariate analysis was performed to investigate the association with socioeconomic, behavioral, and occupational variables...

BACKGROUND: In pig-to-human xenotransplantation, early cellular rejection reactions are mediated by natural killer cells (NK cells). Human NK cells are inhibited by HLA-E via CD94/NKG2A receptors. To protect porcine grafts against human NK cell responses, transgenic GTKO pigs expressing hCD46 and HLA-E have been generated. The aim of this study was to test the effect of this genetic modification on xenogeneic, and in particular human NK cell response, using an ex vivo perfusion model of pig hearts with human blood...

BACKGROUND:  In 1986, Marko Godina published his seminal work regarding the timing of free-flap reconstruction for traumatic extremity defects. Early reconstruction, compared with delayed and late reconstruction resulted in significant decreases in free-flap failure rate, post-operative infections, hospitalization time, bone healing time, and number of additional anesthesias. The objective of this manuscript was to evaluate whether these principles continue to apply. METHODS:  A meta-analysis was performed analyzing articles from Medline, Embase, and Pubmed...

BACKGROUND: People with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) continue to struggle to have their condition recognised as disabling in the face of public and professional prejudice and discrimination. OBJECTIVE: The aim of this study was to compare the functional status and well-being of people with well-characterised ME/CFS with people with multiple sclerosis (PWMS), as well as healthy controls (HCs). METHODS: In this cross-sectional study, we used data collected as part of the UK ME/CFS Biobank to compare actual participant scores from the Medical Outcomes Survey Short Form-36 v2™ (SF-36v2™) between groups, as a proxy for impact of disability, and from a bespoke questionnaire seeking data on employment and income...

Building on previous work in the field, we examined the effect of maternal high fat diet (HFD) during gestation and lactation on the sensitivity of male and female adult offspring to acute and repeated cocaine exposures, and to the expression of cocaine-induced anxiety in the elevated plus maze (EPM). In both male and female offspring, acute injections of cocaine induced a strong locomotor-activating effect; repeated injections produced a robust conditioned locomotor response to the context in which they were given cocaine, and heightened activity in response to a subsequent acute challenge of cocaine...
