Randomized Controlled Trial Multicenter Study
Standardizing the analysis of physical activity in patients with COPD following a pulmonary rehabilitation program.
There is a wide variability in measurement methodology of physical activity. This study investigated the effect of different analysis techniques on the statistical power of physical activity outcomes after pulmonary rehabilitation. ⋯ Changes in physical activity following pulmonary rehabilitation are best measured for 4 weekdays, including only days with at least 8 h of wearing time (during waking hours) and considering the difference in DT as a covariate in the analysis.

Multicenter Study Observational Study
Outcomes for Patients with Cancer Admitted to the ICU Requiring Ventilatory Support: Results from a Prospective Multicenter Study.
This study was undertaken to evaluate the clinical characteristics and outcomes of patients with cancer requiring nonpalliative ventilatory support. ⋯ Patients with cancer with good PS and nonprogressive disease requiring ventilatory support should receive full intensive care, because one-half of these patients survive. On the other hand, provision of palliative care should be considered the main goal for patients with poor PS and progressive underlying malignancy.

COPD guidelines recommend the combined use of inhaled, long-acting β2-agonists and long-acting muscarinic antagonists if symptoms are not improved by a single agent. This systematic review assessed the efficacy and safety of the fixed-dose combination of the long-acting β2-agonist indacaterol and long-acting muscarinic antagonist glycopyrronium (QVA149) compared with its monocomponents (glycopyrronium and indacaterol) and tiotropium for the treatment of moderate to severe COPD. ⋯ Once-daily, inhaled QVA149 showed superior efficacy compared with glycopyrronium and the current standard of care, tiotropium, in patients with moderate to severe COPD.

Randomized Controlled Trial
Omega-3 fatty acid supplementation during pregnancy and respiratory symptoms in Children.
Prenatal consumption of omega-3 fatty acids can act as an adjuvant in the development of the immune system and affect the inflammatory response of neonates. ⋯ Our results support the hypothesis that DHA supplementation during pregnancy may decrease the incidence of respiratory symptoms in children with a history of maternal atopy.

There is no large study validating the appropriateness of current treatment guidelines for Mycobacterium avium complex (MAC) lung disease. This is a retrospective single-center review evaluating the efficacy of macrolide/azalide-containing regimens for nodular/bronchiectatic (NB) MAC lung disease. ⋯ Current guidelines for macrolide/azalide-based therapies for NB MAC lung disease result in favorable microbiologic outcomes for most patients without promotion of macrolide resistance. Intermittent therapy is effective and significantly better tolerated than daily therapy. Microbiologic recurrences during or after therapy are common and most often due to reinfection MAC genotypes.
