Multicenter Study Comparative StudyContinuing to confront COPD International Surveys: comparison of patient and physician perceptions about COPD risk and management.
Using data from the Continuing to Confront COPD International Physician and Patient Surveys, this paper describes physicians' attitudes and beliefs regarding chronic obstructive pulmonary disease (COPD) prognosis, and compares physician and patient perceptions with respect to COPD. ⋯ The Continuing to Confront COPD International Surveys demonstrate that while physicians and patients largely agreed about COPD management practices and the need for more effective treatments for COPD, a gap exists about the causal role of smoking in COPD.

Multicenter Study Comparative Study Observational StudyIs a previous diagnosis of asthma a reliable criterion for asthma-COPD overlap syndrome in a patient with COPD?
Some patients share characteristics of both COPD and asthma. As yet, there is no gold standard to identify patients with the so-called asthma-COPD overlap syndrome (ACOS). ⋯ ACOS patients diagnosed on the basis of a previous diagnosis of asthma differed from the remaining COPD patients, but they were similar to ACOS patients diagnosed according to more restrictive criteria, suggesting that a history of asthma before the age of 40 years could be a useful criterion to suspect ACOS in a patient with COPD.

Multicenter Study Controlled Clinical TrialEffect of severe renal impairment on umeclidinium and umeclidinium/vilanterol pharmacokinetics and safety: a single-blind, nonrandomized study.
Umeclidinium and vilanterol, long-acting bronchodilators for the treatment of chronic obstructive pulmonary disease, are primarily eliminated via the hepatic route; however, severe renal impairment may adversely affect some elimination pathways other than the kidney. ⋯ Umeclidinium 125 μg or umeclidinium/vilanterol 125/25 μg administration to patients with severe renal impairment did not demonstrate clinically relevant increases in systemic exposure compared with healthy volunteers. No dose adjustment for umeclidinium and umeclidinium/vilanterol is warranted in patients with severe renal impairment.

Multicenter StudyComorbidity and health-related quality of life in patients with severe chronic obstructive pulmonary disease attending Swedish secondary care units.
Our understanding of how comorbid diseases influence health-related quality of life (HRQL) in patients with chronic obstructive pulmonary disease (COPD) is limited and in need of improvement. The aim of this study was to examine the associations between comorbidities and HRQL as measured by the instruments EuroQol-5 dimension (EQ-5D) and the COPD Assessment Test (CAT). ⋯ The instruments EQ-5D and CAT complement each other and emerge as useful for assessing HRQL in patients with COPD. Chronic bronchitis, musculoskeletal symptoms, osteoporosis, and depression were associated with worse HRQL. We conclude that comorbid conditions, in particular chronic bronchitis, depression, osteoporosis, and musculoskeletal symptoms, should be taken into account in the clinical management of patients with severe COPD.

Randomized Controlled Trial Multicenter StudyEfficacy and safety of once-daily glycopyrronium in predominantly Chinese patients with moderate-to-severe chronic obstructive pulmonary disease: the GLOW7 study.
Glycopyrronium is a once-daily (od) long-acting muscarinic antagonist for the maintenance treatment of chronic obstructive pulmonary disease (COPD). The GLOW7 study evaluated the efficacy and safety of od glycopyrronium 50 μg in predominantly Chinese patients with moderate-to-severe COPD. ⋯ In predominantly Chinese patients with moderate-to-severe COPD, od glycopyrronium 50 μg significantly improved lung function, dyspnea, and health status compared with placebo. The safety and tolerability profile of glycopyrronium was comparable to placebo.
