Randomized Controlled Trial Comparative StudyCycle ergometer and inspiratory muscle training offer modest benefit compared with cycle ergometer alone: a comprehensive assessment in stable COPD patients.
Cycle ergometer training (CET) has been shown to improve exercise performance of the quadriceps muscles in patients with COPD, and inspiratory muscle training (IMT) may improve the pressure-generating capacity of the inspiratory muscles. However, the effects of combined CET and IMT remain unclear and there is a lack of comprehensive assessment. ⋯ Combined training is more effective than CET alone for increasing inspiratory muscle strength. IMT may not be useful when combined with CET in patients with weakened inspiratory muscles. Nutritional status had slight impact on the effects of pulmonary rehabilitation. A comprehensive assessment approach can be more objective to evaluate the effects of combined CET and IMT.

Randomized Controlled Trial Multicenter StudyUmeclidinium/vilanterol as step-up therapy from tiotropium in patients with moderate COPD: a randomized, parallel-group, 12-week study.
Patients with COPD who remain symptomatic on long-acting bronchodilator monotherapy may benefit from step-up therapy to a long-acting bronchodilator combination. This study evaluated the efficacy and safety of umeclidinium (UMEC)/vilanterol (VI) in patients with moderate COPD who remained symptomatic on tiotropium (TIO). ⋯ UMEC/VI step-up therapy provides clinical benefit over TIO monotherapy in patients with moderate COPD who are symptomatic on TIO alone.

Randomized Controlled TrialBronchodilator efficacy of extrafine glycopyrronium bromide: the Glyco 2 study.
An extrafine formulation of the long-acting muscarinic antagonist glycopyrronium bromide (GB) is in development for chronic obstructive pulmonary disease (COPD), in combination with beclometasone dipropionate and formoterol fumarate - a "fixed triple". This two-part study was randomized, double blind, placebo controlled in patients with moderate-to-severe COPD: Part 1: single-dose escalation, GB 12.5, 25, 50, 100 or 200 μg versus placebo; Part 2: repeat-dose (7-day), four-period crossover, GB 12.5, 25 or 50 μg twice daily (BID) versus placebo, with an open-label extension in which all patients received tiotropium 18 μg once daily. On the morning of Day 8 in all five periods, patients also received formoterol 12 μg. ⋯ All adverse events were mild-moderate in severity and there was no indication of a dose-related relationship. This study provides initial evidence on bronchodilation, safety and pharmacokinetics of extrafine GB BID. Overall, the results suggest that GB 25 μg BID is the optimal dose in patients with COPD.

Randomized Controlled TrialIs cardiac autonomic modulation during upper limb isometric contraction and Valsalva maneuver impaired in COPD patients?
To evaluate the heart rate variability (HRV) indices and heart rate (HR) responses during isometric contraction (IC) and Valsalva maneuver (VM) in COPD patients. ⋯ COPD patients responded properly to the upper limb IC and to the VM; however, HR recovery during VM was impaired in these patients. The severity of the disease and MIP were associated with increased parasympathetic modulation and higher chronotropic response.

Randomized Controlled TrialEffects of a self-management education program on self-efficacy in patients with COPD: a mixed-methods sequential explanatory designed study.
Self-management education programs (SMEPs) are potentially effective in the symptomatic management of COPD. Little is presently known about the effectiveness of these programs in Chinese COPD patients. The objective of this study was to evaluate the effectiveness of a specifically designed SMEP on levels of self-efficacy in Chinese patients with COPD. ⋯ These findings highlight the potential putative benefits of an SMEP in Chinese patients with COPD. Further attention should be given to cultural considerations when developing this type of intervention in Chinese populations with COPD and other chronic diseases.
