[Evaluation on the effect of intervention regarding breast self-examination for decreasing breast cancer mortality].

Objective: A randomized trial of breast self-examination (BSE) Program was carried out to evaluate whether the intensive BSE could reduce the number of deaths among women from breast cancer.

Methods: This study was a randomized controlled trial (RCT). A total of 266 064 women (age of 30 to 64 years) associated with 519 textile factories in Shanghai had been randomly assigned to a BSE group (132 979 women) or a control group (133 085 women) since 1989.

Objective: A randomized trial of breast self-examination (BSE) program was carried out to evaluate whether the intensive BSE can reduce the death number of women from breast cancer.

Methods: A total of 266,064 women (age of 30 to 64 years) associated with 519 textile factories in Shanghai had been randomly assigned to a BSE instruction group (132,979 women) or a control group (133,085 women) since 1989. Initial instruction in BSE group included demonstration of proper palpation techniques.

Is chronic airway obstruction from cotton dust exposure reversible?

Background: Exposure to cotton dust is known to cause chronic airway obstruction, but there is little information on whether the obstructive impairment is reversible after the exposure stops.

Methods: Longitudinal changes in lung function were evaluated among 429 cotton textile workers and 449 silk workers in Shanghai, China, beginning in 1981. Both active and retired workers were tested every 4 to 6 years for 15 years.

Lung function, airway reactivity, and atopy in newly hired female cotton textile workers.

To assess changes in lung function and airway reactivity resulting from exposure to cotton dust, and the role of atopic status in these changes, the authors observed a group of 225 newly hired Chinese textile workers for 1 yr. All workers were female, lifelong nonsmokers, and none of them had been exposed previously to cotton or other occupational dust. Atopic status was determined at baseline.

Randomized trial of breast self-examination in Shanghai: final results.

Background: Among women who practice breast self-examination (BSE), breast cancers may be detected when they are at an earlier stage and are smaller than in women who do not practice BSE. However, the efficacy of breast self-examination for decreasing breast cancer mortality is unproven. This study was conducted to determine whether an intensive program of BSE instruction will reduce the number of women dying of breast cancer.

Follow-up study of respiratory health of newly-hired female cotton textile workers.

Background: Numerous studies have investigated adverse effects of exposure to cotton dust on respiratory health, but very limited longitudinal data are available with regard to the early pulmonary response to cotton dust. Moreover, the adverse effects of occupational exposure to cotton dust have been difficult to separate from the confounding effects of smoking. This setting provided a unique opportunity to evaluate early respiratory effects in newly hired and non-smoking female textile workers.
