Randomized Controlled Trial
Lung Function in Rural Guatemalan Women Before and After a Chimney Stove Intervention to Reduce Woodsmoke Exposure: Results From RESPIRE and CRECER.
COPD is the third most frequent cause of death globally, with much of this burden attributable to household biomass smoke exposure in developing countries. As biomass smoke exposure is also associated with cardiovascular disease, lower respiratory infection, lung cancer, and cataracts, it presents an important target for public health intervention. ⋯ In these young Guatemalan women, there was no association between lung function and early randomization to a chimney stove or personal wood smoke exposure. Future stove intervention trials should incorporate cleaner stoves, longer follow-up, or potentially susceptible groups to identify meaningful differences in lung function.

Randomized Controlled Trial
Effect of CPAP on Cognition, Brain Function and Structure among Elderly Patients with Obstructive Sleep Apnea: a Randomized Pilot Study.
Despite the increasing aging population and the high prevalence of OSA in elderly adults, little is known about cognitive effects of OSA and the effectiveness of CPAP treatment. Therefore, this study investigated whether elderly patients with OSA present cognitive deficits and functional and structural alterations of the brain that could be improved by CPAP treatment. ⋯ Elderly patients with severe OSA who present with cognitive difficulties could benefit from CPAP treatment. Moreover, CPAP treatment increases the connectivity of the DMN and attenuates cortical thinning.

Randomized Controlled Trial
A randomized controlled study to examine the effect of lifestyle modification program in obstructive sleep apnea.
Obesity is an important risk factor for OSA. This study aimed to assess the effect of weight reduction through a lifestyle modification program (LMP) on patients with moderate to severe OSA. ⋯ LMP was effective in reducing the severity of OSA and daytime sleepiness. The beneficial effect was sustained in 12 months.

Randomized Controlled Trial
A double-blind placebo-controlled study of the effects of olprinone, a specific phosphodiesterase-III inhibitor, for preventing postoperative atrial fibrillation in patients undergoing pulmonary resection for lung cancer.
We previously reported that patients with elevated preoperative B-type natriuretic peptide (BNP) levels have an increased risk for postoperative atrial fibrillation following lung cancer surgery. The present study evaluated whether the specific phosphodiesterase III inhibitor olprinone can reduce the incidence of postoperative atrial fibrillation in patients with elevated BNP levels undergoing pulmonary resection for lung cancer. ⋯ Continuous infusion of olprinone during lung cancer surgery was safe and reduced the incidence of postoperative atrial fibrillation following pulmonary resection in patients with elevated preoperative BNP levels.

Randomized Controlled Trial Multicenter Study
Delirium and circadian rhythm of melatonin during weaning from mechanical ventilation: An ancillary study of a weaning trial.
Delirium is frequent in patients in the ICU, but its association with the outcome of weaning from mechanical ventilation has not been assessed. Circadian rhythm alteration may favor delirium. In the current study, we assessed the impact of delirium during weaning and associated alterations in the circadian rhythm of melatonin excretion. ⋯ Delirium is frequent at the initiation of ventilator weaning. It is associated with a prolongation of weaning and an alteration in the circadian rhythm of melatonin excretion.
