Reduced risk of acute exacerbation of COPD after bariatric surgery: a self-controlled case series study.
Little is known about the impact of weight reduction on chronic obstructive pulmonary disease (COPD)-related outcomes in patients who are obese. This study found that the risk of an ED visit or hospitalization for acute exacerbation of COPD substantially decreased after bariatric surgery in patients who are obese. This observation suggests the effectiveness of substantial weight reduction on COPD morbidity.

The impact of untreated obstructive sleep apnea on cardiopulmonary complications in general and vascular surgery: a cohort study.
The purpose of this study was to determine whether preoperatively untreated obstructive sleep apnea (OSA) affects postoperative outcomes. It found that compared with treated OSA, untreated OSA was independently associated with more cardiopulmonary complications (risk-adjusted rates 6.7 percent versus 4.0 percent; particularly unplanned reintubations and myocardial infarction.
