Meta AnalysisPulmonary infection control window as a switching point for sequential ventilation in the treatment of COPD patients: a meta-analysis.
Choosing the appropriate time to switch to noninvasive positive-pressure ventilation (NPPV) plays a crucial role in promoting successful weaning. However, optimal timing for transitioning and weaning patients from mechanical ventilation (MV) to NPPV has not been clearly established. In China, the pulmonary infection control (PIC) window as a switching point for weaning from MV has been performed for many years, without definitive evidence of clinical benefit. This study aimed to summarize the evidence for NPPV at the PIC window for patients with respiratory failure from COPD. ⋯ The results showed that the PIC window as a switching point for sequential ventilation in treatment of respiratory failure in COPD patients may be beneficial. It might yield not only relevant information for caregivers in China but also new insights for considering the PIC window by physicians in other countries.

Randomized Controlled Trial Multicenter StudyEarly efficacy of budesonide/formoterol in patients with moderate-to-very-severe COPD.
Large clinical trials have confirmed the long-term efficacy of inhaled corticosteroid/long-acting β2-agonist combinations in patients with chronic obstructive pulmonary disease (COPD). It was hypothesized that significant treatment effects would already be present within 3 months after the initiation of treatment across a range of clinical outcomes, irrespective of COPD severity. ⋯ Treatment with B/F decreased exacerbations in patients with moderate-to-very-severe COPD within 3 months of commencing treatment. This effect was paralleled by improved lung function, less reliever medication use, and fewer symptoms, irrespective of disease severity.

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.

Multicenter Study Observational StudyCharacteristics of COPD patients according to GOLD classification and clinical phenotypes in the Russian Federation: the SUPPORT trial.
The high prevalence of COPD in the Russian Federation has been demonstrated in several epidemiological studies. However, there are still no data on the clinical characteristics of these patients according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) groups and phenotypes, which could provide additional understanding of the burden of COPD, routine clinical practice, and ways to improve the treatment of patients with COPD in Russia. ⋯ COPD is still misdiagnosed in primary care in Russia. COPD patients in primary care are usually GOLD D with frequent exacerbations and are often treated with only short-acting bronchodilators.

Comparative StudyThe effect of indacaterol/glycopyrronium versus tiotropium or salmeterol/fluticasone on the prevention of clinically important deterioration in COPD.
Endpoints that evaluate deterioration rather than improvement of disease may have clinical utility in COPD. In this analysis, we compared the effects of different maintenance treatments on the prevention of clinically important deterioration (CID) in moderate-to-severe COPD patients. ⋯ These data confirm the utility of the CID endpoint as a means of monitoring COPD worsening in patients with moderate-to-severe COPD. Using the CID measure, we demonstrated that dual bronchodilation with IND/GLY significantly reduced the risk of CID versus either long-acting muscarinic antagonist or long-acting β2-agonist/inhaled corticosteroid treatment, providing further evidence for the benefit of dual bronchodilation in this patient population.
