Review Meta Analysis
Is Quadriceps Endurance Reduced in COPD?: A Systematic Review.
Although the aerobic profile of the quadriceps muscle is reduced in COPD, there is conflicting evidence regarding whether this leads to reduced quadriceps muscle endurance. We, therefore, performed a systematic review of studies comparing quadriceps endurance in individuals with COPD with that in healthy control subjects. ⋯ Quadriceps endurance is reduced in individuals with COPD compared with healthy control subjects, independent of the type of task performed.

Randomized Controlled Trial
Family-based psychosocial support and education as part of pulmonary rehabilitation in COPD: a randomized controlled trial.
Involving family as part of the patient's rehabilitation plan of care might enhance the management of COPD. The primary aim of this study was to investigate the impact of a family-based pulmonary rehabilitation (PR) program on patients and family members' coping strategies to manage COPD. ⋯ This research supports family-based PR programs to enhance coping and psychosocial adjustment to illness of the family system.

Multicenter Study Observational Study
Impact of COPD on the Mortality and Treatment of Patients Hospitalized with Acute Decompensated Heart Failure (The Worcester Heart Failure Study).
COPD is a common comorbidity in patients with heart failure, yet little is known about the impact of this condition in patients with acute decompensated heart failure (ADHF), especially from a more generalizable, community-based perspective. The primary objective of this study was to describe the in-hospital and postdischarge mortality and treatment of patients hospitalized with ADHF according to COPD status. ⋯ COPD is a common comorbidity in patients hospitalized with ADHF and is associated with a worse long-term prognosis. Further research is required to understand the complex interactions of these diseases and ensure that patients with ADHF and COPD receive optimal treatment modalities.

Comparative Study
Misclassification of Obstructive Sleep Apnea Severity with Automated Scoring of Home Sleep Recordings.
The advent of home sleep testing has allowed for the development of an ambulatory care model for OSA that most health-care providers can easily deploy. Although automated algorithms that accompany home sleep monitors can identify and classify disordered breathing events, it is unclear whether manual scoring followed by expert review of home sleep recordings is of any value. Thus, this study examined the agreement between automated and manual scoring of home sleep recordings. ⋯ Although agreement between automated and manual scoring of home sleep recordings varies based on the device used, modest agreement was observed between the two approaches. However, manual review of home sleep test recordings can decrease the misclassification of OSA severity, particularly for those with mild disease.
