Comment Comparative Study
Comparative effectiveness of HIV testing and treatment in highly endemic regions.
Universal testing and treatment holds promise for reducing the burden of human immunodeficiency virus (HIV) in sub-Saharan Africa, but linkage from testing to treatment sites and retention in care are inadequate. ⋯ Universal testing and treatment with current levels of linkage to care and loss to follow-up could substantially reduce the HIV death toll and new HIV infections. However, increasing linkage to care and preventing loss to follow-up provides nearly twice the benefits of universal testing and treatment alone.

Comparative Study
Waist circumference and all-cause mortality in a large US cohort.
Waist circumference (WC), a measure of abdominal obesity, is associated with higher mortality independent of body mass index (BMI). Less is known about the association between WC and mortality within categories of BMI or for the very high levels of WC that are now common. ⋯ These results emphasize the importance of WC as a risk factor for mortality in older adults, regardless of BMI.
