Review Meta AnalysisOnce-daily long-acting beta-agonists for chronic obstructive pulmonary disease: an indirect comparison of olodaterol and indacaterol.
In the absence of head-to-head clinical trials comparing the once-daily, long-acting beta2-agonists olodaterol and indacaterol for the treatment of chronic obstructive pulmonary disease (COPD), an indirect treatment comparison by systematic review and synthesis of the available clinical evidence was conducted. ⋯ When compared under similar trial conditions, olodaterol and indacaterol have similar efficacy in patients with COPD. This research highlights the importance of considering the concomitant COPD medication when evaluating treatment effects in COPD.

Review Meta AnalysisEffects of Tai Chi on exercise capacity and health-related quality of life in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis.
Tai Chi is a traditional Chinese mind-body exercise that has been widely practiced in the People's Republic of China for many centuries. This exercise has also been applied as a training modality in pulmonary rehabilitation programs for stable chronic obstructive pulmonary disease (COPD). This systematic review and meta-analysis aimed to assess the effects of Tai Chi on exercise capacity and health-related quality of life (HRQoL) in COPD patients. ⋯ Preliminary evidence suggests that Tai Chi has beneficial effects on exercise capacity and HRQoL in COPD patients. This exercise can be recommended as an effective alternative training modality in pulmonary rehabilitation programs. Further studies are required to support the preliminary evidence and to observe the long-term effects of Tai Chi.

Review Meta AnalysisDepression and anxiety predict health-related quality of life in chronic obstructive pulmonary disease: systematic review and meta-analysis.
The causal association between depression, anxiety, and health-related quality of life (HRQoL) in chronic obstructive pulmonary disease (COPD) is unclear. We therefore conducted a systematic review of prospective cohort studies that measured depression, anxiety, and HRQoL in COPD. ⋯ Anxiety and depression predict HRQoL in COPD. However, this longitudinal analysis does not show cause and effect relationships between depression and anxiety and future HRQoL. Future studies should identify psychological predictors of poor HRQoL in well designed prospective cohorts with a view to isolating the mediating role played by anxiety disorder and depression.

Review Meta AnalysisOverview of the prevalence, impact, and management of depression and anxiety in chronic obstructive pulmonary disease.
More than one third of individuals with chronic obstructive pulmonary disease (COPD) experience comorbid symptoms of depression and anxiety. This review aims to provide an overview of the burden of depression and anxiety in those with COPD and to outline the contemporary advances and challenges in the management of depression and anxiety in COPD. Symptoms of depression and anxiety in COPD lead to worse health outcomes, including impaired health-related quality of life and increased mortality risk. ⋯ Mindfulness-based treatments are an alternative option for the management of depression and anxiety in people with long-term conditions, but their efficacy is unproven in COPD. Beyond pulmonary rehabilitation, the evidence about optimal approaches for managing depression and anxiety in COPD remains unclear and largely speculative. Future research to evaluate the effectiveness of novel and integrated care approaches for the management of depression and anxiety in COPD is warranted.

Review Meta AnalysisEfficacy of bronchoscopic lung volume reduction: a meta-analysis.
Over the last several years, the morbidity, mortality, and high costs associated with lung volume reduction (LVR) surgery has fuelled the development of different methods for bronchoscopic LVR (BLVR) in patients with emphysema. In this meta-analysis, we sought to study and compare the efficacy of most of these methods. ⋯ The preliminary findings of our meta-analysis signify the importance of most methods of BLVR. The magnitude of the effect on selected primary outcomes shows noninferiority, if not equivalence, when compared to what is known for surgical LVR.
