Randomized Controlled Trial Multicenter Study
Non-invasive positive pressure ventilation for the treatment of severe stable chronic obstructive pulmonary disease: a prospective, multicentre, randomised, controlled clinical trial.
Evidence is weak for the ability of long-term non-invasive positive pressure ventilation (NPPV) to improve survival in patients with stable hypercapnic chronic obstructive pulmonary disease (COPD). Previous prospective studies did not target a reduction in hypercapnia when adjusting ventilator settings. This study investigated the effect of long-term NPPV, targeted to markedly reduce hypercapnia, on survival in patients with advanced, stable hypercapnic COPD. ⋯ German Lung Foundation; ResMed, Germany; Tyco Healthcare, Germany; and Weinmann, Germany.

Randomized Controlled Trial Multicenter Study
Hydrocortisone and fludrocortisone for prevention of hospital-acquired pneumonia in patients with severe traumatic brain injury (Corti-TC): a double-blind, multicentre phase 3, randomised placebo-controlled trial.
Hospital-acquired pneumonia is common after traumatic brain injury, and might be partly a result of traumatic brain injury-induced adrenal insufficiency. We tested the efficacy of low-dose hydrocortisone with fludrocortisone for the prevention of hospital-acquired pneumonia. ⋯ Société Française d'Anesthésie Réanimation.

Randomized Controlled Trial Multicenter Study
Aztreonam for inhalation solution in patients with non-cystic fibrosis bronchiectasis (AIR-BX1 and AIR-BX2): two randomised double-blind, placebo-controlled phase 3 trials.
The clinical benefit of inhaled antibiotics in non-cystic fibrosis bronchiectasis has not been established in randomised controlled trials. We aimed to assess safety and efficacy of aztreonam for inhalation solution (AZLI) in patients with non-cystic fibrosis bronchiectasis and Gram-negative bacterial colonisation. ⋯ Gilead Sciences.

Randomized Controlled Trial
Effect of nicotine patches in pregnancy on infant and maternal outcomes at 2 years: follow-up from the randomised, double-blind, placebo-controlled SNAP trial.
The SNAP (Smoking and Nicotine in Pregnancy) trial compared nicotine replacement therapy (NRT) patches with placebo in pregnant smokers; although NRT doubled cessation rates in the first 4 weeks, by delivery no differences in maternal smoking or birth outcomes were noted. As a result, NRT used in standard doses during pregnancy is considered ineffective for smoking cessation. Subsequent effects of NRT on the children of treated mothers are unknown because no trials have investigated the effect of gestational NRT use beyond birth. To assess whether NRT use in pregnancy might cause harm to infants, we aimed to compare effects of NRT and placebo on infant development 2 years after delivery. ⋯ National Institute for Health Research Health Technology Assessment Programme.
