Home Administration of CVD 103-HgR: A Live Attenuated Oral Cholera Vaccine.

Vaccination is a well-established means for prevention and spread of disease in people traveling abroad. Although vaccines to diseases such as cholera are recommended by world health agencies, they are seldom required even when traveling to endemic regions. Consequences of noncompliance can affect traveler's health and spread diseases to new regions, as occurred in Haiti in 2010 when United Nations peacekeepers from Nepal, where a cholera outbreak was underway, introduced the disease to the region.

Prevalence and correlates of body dysmorphic disorder in health club users in the presence vs absence of eating disorder symptomology.

Purpose: Body dysmorphic disorder (BDD) has been consistently linked with eating disorders, however studies that stratify associations between BDD in subjects with and without eating disorder symptomology are sparse. It was, therefore, the aim of this study to assess correlates of BDD (including social media use, motivations for exercise, exercise addiction, and sexuality) stratified by eating disorder symptomology.

Methods: Cross-sectional study of 1665 health club users recruited online completed a battery of surveys.

Cricketers are not tickled pink by the new coloured ball.

Objectives: Cricket administrators have started scheduling long-form matches which finish at night and are played with a pink as opposed to a red ball. However, there are reports that the pink ball may introduce new dangers and alter performance. The aim of this study was to investigate professional cricketers' opinions about the visibility of the pink ball whilst playing in different lighting conditions (afternoon, dusk and night).

Exercise Addiction Prevalence and Correlates in the Absence of Eating Disorder Symptomology: A Systematic Review and Meta-analysis.

Background: Exercise addiction (EA) can be debilitating and can be a symptom of an eating disorder. To date, the prevalence rates of EA without indicated eating disorders in the general population and associated correlates remain unreported.

Methods: Two authors searched major databases from inception to 31/12/2018 to identify studies investigating the prevalence of EA in any population without indicated eating disorders.

Health behaviours and mental and physical health status in older adults with a history of homelessness: a cross-sectional population-based study in England.

Objectives: This study compared (1) levels of engagement in lifestyle risk behaviours and (2) mental and physical health status in individuals who have previously been homeless to those of individuals who have not.

Design: Cross-sectional.

Participants: Data were from participants (n=6931) of the English Longitudinal Study of Ageing.

Asymmetric diosmium sawhorse complexes.

Three asymmetric diosmium(I) carbonyl sawhorse complexes have been prepared by microwave heating. One of these complexes is of the type Os(μ-OCR)(μ-OCR')(CO)L, with two different bridging carboxylate ligands, while the other two complexes are of the type Os(μ-OCR)(CO)L, with one axial CO ligand and one axial phosphane ligand. The mixed carboxylate complex Os(μ-acetate)(μ-propionate)(CO)[P(p-tolyl)], (1), was prepared by heating Os(CO) with a mixture of acetic and propionic acids, isolating Os(μ-acetate)(μ-propionate)(CO), and then replacing two CO ligands with two phosphane ligands.

Promoting physical activity in vulnerable adults 'at risk' of homelessness: a randomised controlled trial protocol.

Introduction: People who are homeless, or at risk of homelessness, have substantially poorer health. Sustained and regular participation in physical activity is beneficial for both mental and physical health. Limited data suggest that levels of physical activity in the homeless and those at risk of homelessness are low, and access to community-based exercise is limited or non-existent for this population.

Telomere length and health outcomes: An umbrella review of systematic reviews and meta-analyses of observational studies.

The aim of the present study was to map and grade evidence for the relationships between telomere length with a diverse range of health outcomes, using an umbrella review of systematic reviews with meta-analyses. We searched for meta-analyses of observational studies reporting on the association of telomere length with any health outcome (clinical disease outcomes and intermediate traits). For each association, random-effects summary effect size, 95% confidence interval (CI), and 95% prediction interval were calculated.

Effect of a short-term low fermentable oligiosaccharide, disaccharide, monosaccharide and polyol (FODMAP) diet on exercise-related gastrointestinal symptoms.

Background: Research has demonstrated that low fermentable oligiosaccharide, disaccharide, monosaccharide and polyol (FODMAP) diets improve gastrointestinal (GI) symptoms in irritable bowel syndrome sufferers. Exercise-related GI issues are a common cause of underperformance, with current evidence focusing on the use of FODMAP approaches with recreationally competitive or highly trained athletes. However, there is a paucity of research exploring the potential benefit of FODMAP strategies to support healthy, recreational athletes who experience GI  issues during training.

Satiating Effect of High Protein Diets on Resistance-Trained Subjects in Energy Deficit.

Short-term energy deficit strategies are practiced by weight class and physique athletes, often involving high protein intakes to maximize satiety and maintain lean mass despite a paucity of research. This study compared the satiating effect of two protein diets on resistance-trained individuals during short-term energy deficit. Following ethical approval, 16 participants (age: 28 ± 2 years; height: 1.

The effect of two β-alanine dosing strategies on 30-minute rowing performance: a randomized, controlled trial.

Background: β-alanine (βA) supplementation has been shown to increase intramuscular carnosine content and subsequent high-intensity performance in events lasting < 4 minutes (min), which may be dependent on total, as opposed to daily, dose. The ergogenic effect of βA has also been demonstrated for 2000-m rowing performance prompting interest in whether βA may be beneficial for sustained aerobic exercise. This study therefore investigated the effect of two βA dosing strategies on 30-min rowing and subsequent sprint performance.

Physical inactivity in relation to self-rated eyesight: cross-sectional analysis from the English Longitudinal Study of Ageing.

Background: To assess the cross-sectional association between self-rated eyesight and physical activity behaviour in a large general population sample of older English adults.

Methods: Analyses of data from the English Longitudinal Study of Ageing. Participants provided information on self-rated eyesight (categorised as: excellent/very good/good/fair-poor) and their own physical activity levels (categorised as: inactive/moderate only at least 1/week, vigorous at least 1/week).

Prospective associations between measures of gross and fine motor coordination in infants and objectively measured physical activity and sedentary behavior in childhood.

One important determinant of childhood physical activity and sedentary behavior may be that of motor development in infancy. The present analyses aimed to investigate whether gross and fine motor delays in infants were associated with objective and self-reported activity in childhood. Data were from the UK Millennium Cohort Study, a prospective cohort study, involving UK children born on or around the millennium (September 2000 and January 2002).

Accelerometery and Heart Rate Responses of Professional Fast-Medium Bowlers in One-Day and Multi-Day Cricket.

The physical demands of fast-medium bowling are increasingly being recognised, yet comparative exploration of the differing demands between competitive formats (i.e. one-day [OD] versus multi-day [MD] matches) remain minimal.

Correlates of children's independent outdoor play: Cross-sectional analyses from the Millennium Cohort Study.

Time spent outdoors is associated with higher levels of physical activity. To date, correlates of independent outdoor play have not been investigated. This study aimed to identify potential demographic, behavioural, environmental and social correlates of children's independent outdoor play.

Present-day and future climate pathways affecting Alexandrium blooms in Puget Sound, WA, USA.

This study uses a mechanistic modeling approach to evaluate the effects of various climate pathways on the proliferative phase of the toxin-producing dinoflagellate Alexandrium in Puget Sound, WA, USA. Experimentally derived Alexandrium growth responses to temperature and salinity are combined with simulations of the regional climate and Salish Sea hydrology to investigate future changes in the timing, duration, and extent of blooms. Coarse-grid (100-200km) global climate model ensemble simulations of the SRES A1B emissions scenario were regionally downscaled to a 12-km grid using the Weather Research and Forecasting model for the period 1969-2069.

Atmospheric controls on northeast Pacific temperature variability and change, 1900-2012.

Over the last century, northeast Pacific coastal sea surface temperatures (SSTs) and land-based surface air temperatures (SATs) display multidecadal variations associated with the Pacific Decadal Oscillation, in addition to a warming trend of ∼ 0.5-1 °C. Using independent records of sea-level pressure (SLP), SST, and SAT, this study investigates northeast (NE) Pacific coupled atmosphere-ocean variability from 1900 to 2012, with emphasis on the coastal areas around North America.
