TL;DR: A low BMI is associated with the presence of emphysema, but not with airway wall thickening, in male smokers who have COPD, which support the concept of different COPD phenotypes and suggest that there may be different systemic manifestations of these phenotypes.

TL;DR: IOS measurements, especially indices of peripheral airway function, are significantly correlated with health status and dyspnea in patients with COPD and may be a useful clinical tool not only for detecting pulmonary functional impairment, but also to some extent at least estimating the patient's quality of daily life and well-being.

TL;DR: The objective of this study was to investigate the annual changes in airway dimensions and lung attenuation using CT in patients with COPD and to evaluate the correlations among annualChanges in CT measurements and pulmonary function.

TL;DR: The first objective was to compare airway dimensions of the basal segment bronchus between COPD patients and healthy controls, and to investigate the relationship between CT measurements and pulmonary function among COPd patients.

TL;DR: This study clarified the mechanism of LPS‐induced CTGF expression in bronchial epithelial cells and suggested that it may have a considerable impact on the airway epithelium, in terms of cytokine and growth factor production.
