Review Meta Analysis
Bidirectional Associations Between Clinically Relevant Depression or Anxiety and COPD: A Systematic Review and Meta-analysis.
The longitudinal associations between depression or anxiety and COPD, and their comorbid effect on prognosis, have not been adequately addressed by previous reviews. We aimed to systematically assess these associations to inform guidelines and practice. ⋯ Depression and anxiety adversely affect prognosis in COPD, conferring an increased risk of exacerbation and possibly death. Conversely, COPD increases the risk of developing depression. These bidirectional associations suggest potential usefulness of screening for these disease combinations to direct timely therapeutic intervention.

Randomized Controlled Trial Multicenter Study Comparative Study
Longitudinal trends in health-related quality of life in adults with cystic fibrosis.
Health-related quality-of-life (HRQOL) measures have been used as patient-reported outcomes in clinical trials in cystic fibrosis (CF), but there are limited data on HRQOL changes over time in adults with CF. ⋯ In a longitudinal multicenter population of adults with CF, clinical variables such as FEV1, exacerbation frequency, and weight were correlated with related CFQ-R subscales. For the population as a whole, the physical domains of CFQ-R, such as respiratory symptoms, were stable. In contrast, population changes in several psychosocial domains of CFQ-R suggest that differentiating between the physical and the psychosocial trajectories in health among adults with CF is critical in evaluating patient-reported outcomes.

Comparative Study
Sleep-disordered breathing and postoperative outcomes after elective surgery: analysis of the nationwide inpatient sample.
Systematic screening and treatment of sleep-disordered breathing (SDB) or obstructive sleep apnea (OSA) in presurgical patients would impose a significant cost burden; therefore, it is important to understand whether SDB is associated with worse postoperative outcomes. We sought to determine the impact of SDB on postoperative outcomes in patients undergoing four specific categories of elective surgery (orthopedic, prostate, abdominal, and cardiovascular). The primary outcomes were in-hospital death, total charges, and length of stay (LOS). Two secondary outcomes of interest were respiratory and cardiac complications. ⋯ In this large national study, despite the increased independent association of SDB with postoperative cardiopulmonary complications, the diagnosis of SDB was not independently associated with an increased rate of in-hospital death. SDB had a mixed impact on LOS and total charges by surgical category.

American Thoracic Society guidelines support using fractional exhaled nitric oxide (FENO) measurements in patients with asthma and highlight gaps in the evidence base. Little is known about the use of FENO levels to predict asthma exacerbations among high-risk, urban, minority populations receiving usual care. ⋯ FENO level may not be a clinically useful predictor of health-care use for asthma exacerbations in urban minority children with asthma.
