TL;DR: Despite a substantial prevalence of asthma in the COVID-19 cohort, asthma was not associated with an increased risk of hospitalization and the ongoing use of ICS did not increase the risk ofospitalization in a similar adjusted model.

TL;DR: Occasional and low cumulative marijuana use was not associated with adverse effects on pulmonary function, and tobacco exposure, both current and lifetime, was linearly associated with lower FEV(1) and FVC.

TL;DR: Among patients with emphysema and severe hyperinflation treated for 12 months, the use of endobronchial coils compared with usual care resulted in an improvement in median exercise tolerance that was modest and of uncertain clinical importance, with a higher likelihood of major complications.

TL;DR: Ventilation with a low TV was used in a minority of patients with acute lung injury, despite results published in 1998 and 2000 supporting this approach, which may be related to clinicians’ underrecognition of less severe cases of ALI, their reserving of low-TV ventilation for more severe cases, or both.

TL;DR: PH is common in advanced COPD and is associated with functional impairment and an increased mortality risk, and Stratification by RHC determined pulmonary hemodynamics appears important in distinguishing distinct clinical phenotypes.
