IFN-γ +874 A>T (rs2430561) gene polymorphism and risk of pulmonary tuberculosis: a meta-analysis.
The role of interferon gamma (IFN-γ) +874 A>T (rs2430561) gene polymorphism has been evaluated in different ethnicities with pulmonary tuberculosis (PTB) infection, and inconsistent results have been reported. In this study, a meta-analysis was performed to determine the precise association between IFN-γ +874 A>T gene polymorphism and PTB susceptibility. ⋯ In conclusion, the IFN-γ +874 A>T gene polymorphism is significantly associated with reduced risk of PTB, showing a protective effect in the overall and in the Caucasian population. However, this polymorphism is not associated with PTB risk in the Asian population.

This is a report of a systematic review of the safety and efficacy of naltrexone or naltrexone/bupropion on weight loss. ⋯ Based on these studies, it can be said that naltrexone/bupropion treatment is effective in the weight loss of overweight subjects. The naltrexone/bupropion treatment was well tolerated by the patients, and side effects were rarely reported.

Worse survival in upper tract urothelial carcinoma (UTUC) in the presence of a tumour in the ureter vs. pelvicalyceal tumours is reported in some studies; however, the definition of ureteral involvement (UI) varies across studies. We systematically evaluated evidence regarding the prognostic role of UI in overall and cancer-specific survival of patients with UTUC. ⋯ Our meta-analysis identified UI in UTUC as an adverse prognostic factor.

Does a high-fat diet-induced obesity model brown adipose tissue thermogenesis? A systematic review.
In this systematic review, we analysed studies that assessed the brown adipose tissue (BAT) activity in the high-fat/cafeteria diet model of obesity in rats. ⋯ Despite the consolidated use of high-fat/cafeteria diets as a model to induce obesity, the identification of the energy expenditure arm has been slow, especially the direct quantitative assessment of the contribution of BAT to the increase in metabolic rate in rats fed a cafeteria/high-fat diet.
