Despite the wide-ranging benefits of pulmonary rehabilitation, conflicting results remain regarding whether people with COPD can improve their peak oxygen uptake (V˙O2peak) with aerobic training. ⋯ PROSPERO; No.: CRD42018099300; URL: https://www.crd.york.ac.uk/prospero/.

Randomized Controlled Trial
Randomized trial on the effects of high-dose zopiclone on OSA severity, upper airway physiology and alertness.
Studies indicate that standard doses of hypnotics reduce or do not change the apnea-hypopnea index (AHI) or pharyngeal muscle activity. A 1-month trial of nightly zopiclone (7.5 mg) modestly reduced the AHI vs baseline without changing other sleep parameters or next-day sleepiness. ⋯ A single night of treatment with high-dose zopiclone does not systematically reduce the AHI or increase the arousal threshold in selected people with OSA. The mechanisms for these unexpected findings require further investigation.

Multicenter Study
Differences in clinical characteristics and outcomes between men and women with idiopathic pulmonary fibrosis: a multicenter retrospective cohort study.
Idiopathic pulmonary fibrosis (IPF) is a disease with a male predominance. Prior data suggest that male sex is associated with disease progression and survival. The basis for this sex difference is unknown. ⋯ Male sex is associated with worse transplant-free survival in IPF. Cough may be a sex-specific predictor of survival in this population.

Randomized Controlled Trial
Outcomes of Metabolic Resuscitation Using Ascorbic Acid, Thiamine, and Glucocorticoids in the Early Treatment of Sepsis.
Sepsis is a major public health burden resulting in 25% to 30% in-hospital mortality and accounting for over 20 billion dollars of US hospital costs. ⋯ Our results suggest that the combination of IV ascorbic acid, thiamine, and hydrocortisone significantly reduced the time to resolution of shock. Additional studies are needed to confirm these findings and assess any potential mortality benefit from this treatment.

Lung cancer screening, despite its proven mortality benefit, remains vastly underutilized. Previous studies examined knowledge, attitudes, and beliefs to better understand the reasons underlying the low screening rates. These investigations may have limited generalizability because of traditional participant recruitment strategies and examining only subpopulations eligible for screening. The current study used crowdsourcing to recruit a broader population to assess these factors in a potentially more general population. ⋯ Although a minority of individuals at high risk for lung cancer are aware of screening, the majority believe that early detection saves lives and would pursue screening if recommended by their primary care physician. Health systems may increase screening rates by improving patient and physician awareness of lung cancer screening.
