BACKGROUND Physical activity (PA) is considered a cornerstone of diabetes mellitus management to prevent complications, but conclusive evidence is lacking. METHODS This prospective cohort study and meta-analysis of existing studies investigated the association between PA and mortality in individuals with diabetes. In the EPIC study (European Prospective Investigation Into Cancer and Nutrition), a cohort was defined of 5859 individuals with diabetes at baseline. ⋯ CONCLUSIONS Higher levels of PA were associated with lower mortality risk in individuals with diabetes. Even those undertaking moderate amounts of activity were at appreciably lower risk for early death compared with inactive persons. These findings provide empirical evidence supporting the widely shared view that persons with diabetes should engage in regular PA.

There is interest in whether a short course of combination antiretroviral therapy (cART) at the time of human immunodeficiency virus (HIV) seroconversion could induce long-term immunologic control after its interruption. We aimed to determine the time of virologic rebound after interruption of treatment initiated close to HIV seroconversion and to identify potential cases of posttreatment controllers (PTCs) in the CASCADE (Concerted Action on Seroconversion to AIDS and Death in Europe) Collaboration. ⋯ Most patients experience virologic rebound soon after cART interruption; however, although PTCs are rare, the results of this study confirm their existence.

In screening pharmaceuticals for possible carcinogenic effects we noted an association between lip cancer risk and the photosensitizing antihypertensive drugs hydrochlorothiazide and nifedipine. In this study, we further characterized the risk of lip cancer associated with these and other commonly used antihypertensive drugs. ⋯ These data support an increased risk of lip cancer in non-Hispanic whites receiving treatment for hypertension with long-term use of photosensitizing drugs.

The association of hypertension and mortality is attenuated in elderly adults. Walking speed, as a measure of frailty, may identify which elderly adults are most at risk for the adverse effects of hypertension. We hypothesized that elevated blood pressure (BP) would be associated with a greater risk of mortality in faster-, but not slower-, walking older adults. ⋯ Walking speed could be a simple measure to identify elderly adults who are most at risk for adverse outcomes related to high BP.
