Randomized Controlled Trial Multicenter Study
A randomized trial of prolonged co-trimoxazole in HIV-infected children in Africa.
Co-trimoxazole (fixed-dose trimethoprim-sulfamethoxazole) prophylaxis administered before antiretroviral therapy (ART) reduces morbidity in children infected with the human immunodeficiency virus (HIV). We investigated whether children and adolescents receiving long-term ART in sub-Saharan Africa could discontinue co-trimoxazole. ⋯ Continuing co-trimoxazole prophylaxis after 96 weeks of ART was beneficial, as compared with stopping prophylaxis, with fewer hospitalizations for both malaria and infection not related to malaria.

Randomized Controlled Trial Multicenter Study
Stenting and medical therapy for atherosclerotic renal-artery stenosis.
Atherosclerotic renal-artery stenosis is a common problem in the elderly. Despite two randomized trials that did not show a benefit of renal-artery stenting with respect to kidney function, the usefulness of stenting for the prevention of major adverse renal and cardiovascular events is uncertain. ⋯ Renal-artery stenting did not confer a significant benefit with respect to the prevention of clinical events when added to comprehensive, multifactorial medical therapy in people with atherosclerotic renal-artery stenosis and hypertension or chronic kidney disease.

Distracted driving attributable to the performance of secondary tasks is a major cause of motor vehicle crashes both among teenagers who are novice drivers and among adults who are experienced drivers. ⋯ The risk of a crash or near-crash among novice drivers increased with the performance of many secondary tasks, including texting and dialing cell phones.
