Exposure to environmental tobacco smoke (ETS) is associated with impaired lung function in childhood, which in turn, is associated with chronic obstructive pulmonary disease (COPD) in adulthood. However, little is known regarding the direct association between childhood exposure to ETS and the development of COPD. The main objective of the present study was to examine the associations between childhood ETS exposure and adult COPD and respiratory symptoms. ⋯ Exposure to ETS during childhood was associated with COPD and respiratory symptoms in adulthood. Although active smoking is still the most important risk factor for COPD, reduction of childhood ETS exposure could contribute to the prevention of COPD and respiratory symptoms.

A well-validated instrument that is simple to use is needed to assess health-related quality of life in patients with interstitial lung disease (ILD). The COPD assessment test (CAT) is a recently introduced, short and simple questionnaire for COPD patients, which shows good and valid measurement properties. This study was conducted to evaluate the validity of the CAT in patients with ILD. ⋯ The CAT is a short and simple questionnaire that shows good and valid measurement properties for assessing the health status of patients with ILD.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy and safety of indacaterol 150 and 300 µg in chronic obstructive pulmonary disease patients from six Asian areas including Japan: a 12-week, placebo-controlled study.
The efficacy and safety of indacaterol, a novel inhaled once daily ultra long-acting β(2) -agonist was evaluated in COPD patients in six Asian countries/areas. This study was primarily designed to obtain the regulatory approval of indacaterol in Japan. ⋯ Indacaterol provided clinically significant bronchodilation and improvements in dyspnoea and health status in Asian COPD patients.
