Randomized Controlled TrialSelf-reported sleep quality and acute exacerbations of chronic obstructive pulmonary disease.
Many patients with chronic obstructive pulmonary disease (COPD) suffer from poor sleep quality. We hypothesized that poor sleep quality in otherwise stable patients predicted exacerbations in these patients. ⋯ Poor sleepers had greater exacerbation rates than did good sleepers. This appeared to be due largely to them having more, or more severe, concomitant medical conditions and taking more medications.

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.

Randomized Controlled TrialThe one repetition maximum test and the sit-to-stand test in the assessment of a specific pulmonary rehabilitation program on peripheral muscle strength in COPD patients.
Individuals with COPD may present reduced peripheral muscle strength, leading to impaired mobility. Comprehensive pulmonary rehabilitation (PR) should include strength training, in particular to lower limbs. Furthermore, simple tools for the assessment of peripheral muscle performance are required. ⋯ Our study shows that in stable moderate-to-severe inpatients with COPD, STST is a valid and reliable tool to assess peripheral muscle performance of lower limbs, and is sensitive to a specific PR program.

Randomized Controlled TrialCardiovascular and inflammatory effects of simvastatin therapy in patients with COPD: a randomized controlled trial.
There is excess cardiovascular mortality in patients with chronic obstructive pulmonary disease. Aortic stiffness, an independent predictor of cardiovascular risk, and systemic and airway inflammation are increased in patients with the disease. Statins modulate aortic stiffness and have anti-inflammatory properties. A proof-of-principle, double-blind, randomized trial determined if 6 weeks of simvastatin 20 mg once daily reduced aortic stiffness and systemic and airway inflammation in patients with chronic obstructive pulmonary disease. ⋯ There was a nonsignificant improvement in aortic PWV in those taking simvastatin 20 mg compared with placebo, but in those with higher baseline aortic stiffness (a higher risk group) a significant and clinically relevant reduction in PWV was shown.

Randomized Controlled TrialA pilot study: mindfulness meditation intervention in COPD.
Living well with chronic obstructive pulmonary disease (COPD) requires people to manage disease-related symptoms in order to participate in activities of daily living. Mindfulness practice is an intervention that has been shown to reduce symptoms of chronic disease and improve accurate symptom assessment, both of which could result in improved disease management and increased wellness for people with COPD. A randomized controlled trial was conducted to investigate an 8-week mindful meditation intervention program tailored for the COPD population and explore the use of breathing timing parameters as a possible physiological measure of meditation uptake. ⋯ Furthermore, those who completed six or more classes (N=12) demonstrated significant improvement in emotional function in comparison to the wait-list group (P=0.032) even though their level of mindfulness did not improve. This study identifies that there may be a complex relationship between breathing parameters, emotion, and mindfulness in the COPD population. The results describe good feasibility and acceptability for meditation interventions in the COPD population.
