Communicable diseases are common in people who are incarcerated. We aimed to define the prevalence of chlamydia, gonorrhoea and syphilis in people who are incarcerated and to identify subgroups with the highest risk of infection. We searched for prevalence studies of chlamydia, gonorrhoea or syphilis in incarcerated populations. Pooled estimates were generated, and meta-regression was conducted. Random effects models yielded pooled prevalence estimates of 5.75% (95% confidence interval [CI] 5.01, 6.48) and 12.31% (95% CI 10.61, 14.01) for chlamydia in men and women, 1.4% (95% CI 1.09, 1.70) and 5.73% (4.76, 6.69) for gonorrhoea in men and women, and 2.45% (95% CI 2.08, 2.82) and 6.10% (95% CI 4.75, 7.46) for syphilis in men and women, respectively. Each infection was associated with female gender in meta-regression models. Chlamydia, gonorrhoea and syphilis are highly prevalent in these populations. Primary and secondary prevention efforts could improve individual and population health.

Experienced professionals often do not recognise stool colour associated with biliary obstruction. The authors propose that stool colour cards similar to those used in Japan and Taiwan may improve early detection of hepatobiliary disease at a minimal cost.

Obesity, a dysregulation of adipose tissue, is a major health risk factor associated with many diseases. Brown adipose tissue (BAT)-mediated thermogenesis can potentially regulate energy expenditure, making it an attractive therapeutic target to combat obesity. Here, we characterize the effects of cold exposure, thermoneutrality, and high-fat diet (HFD) feeding on mouse supraclavicular BAT (scBAT) morphology and BAT-associated gene expression compared to other adipose depots, including the interscapular BAT (iBAT). scBAT was as sensitive to cold induced thermogenesis as iBAT and showed reduced thermogenic effect under thermoneutrality. While both scBAT and iBAT are sensitive to cold, the expression of genes involved in nutrient processing is different. The scBAT also showed less depot weight gain and more single-lipid adipocytes, while the expression of BAT thermogenic genes, such as Ucp1, remained similar or increased more under our HFD feeding regime at ambient and thermoneutral temperatures than iBAT. Together, these findings show that, in addition to its anatomical resemblance to human scBAT, mouse scBAT possesses thermogenic features distinct from those of other adipose depots. Lastly, this study also characterizes a previously unknown mouse deep neck BAT (dnBAT) depot that exhibits similar thermogenic characteristics as scBAT under cold exposure and thermoneutrality.

Aims:The aim of the study was to perform a systematic review and meta-analysis to determine the association between antidepressants use and risk of myocardial infarction (MI), and whether this association differs between tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs).Methods:A PubMed/MEDLINE search was conducted for studies published up to December 2013. Included studies were evaluated for publication bias and heterogeneity. Depending on the presence of heterogeneity, a random or fixed effects model was used to identify the pooled relative risk (RR) with 95% confidence intervals (CIs). Cumulative meta-analysis, subgroup and sensitivity analyses were also performed. All analyses were performed using comprehensive meta-analysis software.Results:Fourteen (five cohort and nine case–control) studies were included. There was heterogeneity among the studies (Pheterogeneity = 0.02; I2 = 68%) but no publication bias (Begg's P = 0.30 and Egger's P = 0.45). Antidepressants use significantly increases the risk of myocardial infarction (MI) (RR = 2.03; 95% CI = 1.30–3.18; P < 0.01). On subgroup analysis by study design, cohort studies show significant positive association (RR = 2.16; 95% CI = 1.42–3.29; P < 0.01), but not case–control studies (RR = 2.47; 95% CI = 0.69–8.90; P = 0.17). Sensitivity analysis and cumulative meta-analysis confirmed the stability of results. TCAs users are having 36% increased risk of MI after excluding one outlier (RR = 1.36; 95% CI = 1.10–1.67; P < 0.01), but SSRIs showing no association (RR = 0.84; 95% CI = 0.57–1.22; P = 0.35).Conclusions:We found evidence that the use of antidepressants was associated with elevated risk of MI. Further research is needed to identify the underlying biological mechanisms.
