Multicenter Study
Survey on the handling of chronic obstructive pulmonary disease by annual health check in Japan.
Since mild COPD can be detected in the annual health check by lung function tests, we conducted a questionnaire survey on how such examinations are used to assess chronic obstructive pulmonary disease (COPD). ⋯ At most facilities performing a comprehensive medical check-up, there was not a sufficient number of respirologists to ensure early diagnosis of COPD and this may have compromised COPD diagnosis. The newly proposed Japan Society of Comprehensive Medical Check-up (Ningen-dock) Standards based on the Japanese Respiratory Society may be useful to reveal early stages of COPD.

Multicenter Study Comparative Study
Gender-related and city- and countryside-related differences in patients with ulcerative colitis in a Chinese population.
The purpose of this study is to determine gender-related and city- and countryside-related differences of ulcerative colitis in a Chinese population, and to determine information on the role of lifestyle in the onset of ulcerative colitis. ⋯ Both gender-related and city- and countryside-related differences were found in the expression of ulcerative colitis in the Chinese population. Lifestyle factors such as psychological stress and fatigue may contribute to the expression of ulcerative colitis.
