Negative pressure wound therapy promotes wound drainage and may increase the formation of granulation tissue. In a randomized clinical trial of negative pressure wound therapy vs standard wound dressings in 460 patients with open fractures of the lower limb, Costa and colleagues for the UK WOLFF Collaboration found no difference in self-rated disability at 12 months after injury.
Depression is an adverse event associated with many prescription medications. In a study of 26 192 US adults interviewed for the National Health and Nutrition Examination Survey, Qato and colleagues found that the likelihood of depression was greatest in patients taking 3 or more medications listed as having depression as a possible adverse effect.
Pentraxin 2 inhibits the production of transforming growth factor-β1, a key mediator of pulmonary fibrosis. Raghu and colleagues randomized 117 patients with idiopathic pulmonary fibrosis and found that treatment with recombinant human pentraxin 2 vs placebo resulted in a slower decline in lung function over 28 weeks. In an Editorial, Gibson and Kass suggest that future trials of therapies for idiopathic pulmonary fibrosis should address exercise capacity as well as change in pulmonary function.

This US Preventive Services Task Force statement recommends against screening with electrocardiography in asymptomatic adults at low risk of cardiovascular events. In an Editorial, Myerburg suggests that more research is needed on the efficacy of electrocardiography screening for special populations such as athletes.
