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.

Deterioration of quality of life is associated with the exacerbation frequency in individuals with alpha-1-antitrypsin deficiency - analysis from the German Registry.
Alpha-1-antitrypsin deficiency (AATD) is a rare hereditary disease that is associated with a higher risk to develop chronic obstructive pulmonary disease and liver cirrhosis. Previous cross-sectional studies on AATD individuals have shown a relationship between worse St George's Respiratory Questionnaire (SGRQ) scores and elevated exacerbation rate or high cigarette consumption. There is a lack of longitudinal data on the relationship between the exacerbation rate and worsening of SGRQ during disease. The aim of this study was to provide not only cross-sectional data but also information about the deterioration in quality of life over a follow-up period up to 7 years (median follow-up period of 3.33 years). ⋯ Worsening of SGRQ is associated with the exacerbation frequency in individuals with PiZZ AATD.

Observational StudyA nationwide structure for valid long-term oxygen therapy: 29-year prospective data in Sweden.
Long-term oxygen therapy (LTOT) improves prognosis in COPD with severe hypoxemia. However, adherence to criteria for eligibility and quality of LTOT is often insufficient and varies between countries. The aim of this study was to evaluate a national structure for prescription and management of LTOT over three decades in Sweden. ⋯ We present a structure for prescription, management, and follow-up of LTOT. The national registry effectively monitored adherence to prescription recommendations and most likely contributed to improved quality of care.

Long-term effects of beta-blocker use on lung function in Japanese patients with chronic obstructive pulmonary disease.
Some recent studies have suggested that beta-blocker use in patients with chronic obstructive pulmonary disease (COPD) is associated with a reduction in the frequency of acute exacerbations. However, the long-term effects of beta-blocker use on lung function of COPD patients have hardly been evaluated. ⋯ Long-term beta-blocker use in Japanese COPD patients might not affect the FEV1, one of the most important parameters of lung function in COPD patients.

Comparative StudyComparative study on medical utilization and costs of chronic obstructive pulmonary disease with good lung function.
Patients with mild to moderate chronic obstructive pulmonary disease (COPD) are underdiagnosed and undertreated due to the asymptomatic nature of the disease. Previous studies on patients with mild COPD have focused on symptomatic patients. Therefore, in this study, we evaluated the treatment status of patients with early COPD in Korea. ⋯ Medical resource utilization and medical costs per person for patients with early COPD in Korea increased. However, asymptomatic patients with COPD represented by the KNHANES group do not receive adequate long-term treatment compared to relatively symptomatic patients, and require more clinical attention from physicians.
