Background: Most Neisseria gonorrhoea (GC) and Chlamydia trachomatis (CT) infections in men who have sex with men (MSM) are diagnosed at extragenital sites. However, testing at these sites is often lacking. The purpose of this study was to determine if a standardized questionnaire administered by physicians and clinical assistants improves documentation of sex activity and increases extragenital testing and diagnoses of GC and CT among MSM.

We exploit the roll-out of universal provision across Local Authorities to estimate effects at different ages and durations of exposure, based on nurse-collected, population-wide health data for state school children. Exposure to universal free lunches reduces obesity prevalence and BMI among children aged 4-5 and 10-11, but older children's bodyweights are less responsive than younger children's.

These parameters are often treated as constants regardless of the static stability at the ice-ocean interface. This study investigates the variability of and based on direct observations of thermal and kinetic energy balance.

However, a myriad of conditions can cause a miliary pattern, many of which are imminently life-threatening. The primary aim of our study is to elucidate the potential causes of miliary chest imaging patterns to improve workup and empiric therapy selection.

Sentinel cages are an established means of assessing infestation pressure at fixed locations, but as smolts move through systems they will be exposed to varying lice densities. As a means of assessing infestation pressure along trajectories, we describe the development and application of towed sentinel cages (TSCs) in a Scottish sea loch containing salmonid aquaculture.
