The Effectiveness of a Training Program on Reducing Needlestick Injuries/Sharp Object Injuries among Soon Graduate Vocational NursingSchool Students in Southern Taiwan: Ya-Hui YANG, et al. Institute of Occupational Safety and Health, Kaohsiung Medical University, Taiwan-Needlestick/ sharp injuries (NSIs/SIs) are a serious threat to medical/ nursing students in hospital internships. Education for preventing NSIs/SIs is important for healthcare workers but is rarely conducted and evaluated among vocational school nursing students. We conducted an educational intervention for such students after their internship rotations before graduation. This program consisted of a lecture to the students after the internship training and a self-study brochure for them to study before their graduation. This study used the pre-test questionnaires completed by all students and the post-test questionnaires completed by 107 graduates after work experience as licensed nurses to assess the effectiveness of the intervention. After educational intervention, the incidence of NSIs/SIs decreased significantly from 50.5% pre-test to 25.2% post-test, and the report rate increased from 37.0% to 55.6%, respectively. In conclusion, this intervention significantly reduced the incidence of NSIs/SIs and increased the report rate of such events. (J Occup Health 2007; 49: 424-429)

The relationship between breast cancer mortality and air pollution was examined using an ecological design. The study areas consisted of 61 municipalities in Taiwan. Air quality data for recorded concentrations of fine particulate matter (PM 2.5 ) from study municipalities for 2006-2009 were obtained as a marker of traffic emissions and were used as a proxy for polycyclic aromatic hydrocarbons (PAHs) exposure. Age-standardized mortality rates for breast cancer mortality were calculated for the study municipalities for the years 1999-2008. A weighted multiple regression model was used to calculate the adjusted risk ratio in relation to PM 2.5 levels. Results showed that individuals who resided in municipalities with the highest PM 2.5 were at an increased risk of death from breast cancer. This study is the first to suggest that exposure to high levels of PM 2.5 , a proxy measure of PAHs, may be associated with an increased risk of death from breast cancer. The findings of this study warrant further investigation into the role of air pollutants in the risk of breast cancer.

One hundred and sixty-nine and 175 cotton textile workers (CTWs) were enrolled in the first (1991) and second (1996) surveys to investigate the prevalence of byssinosis. The synergistic effect of smoking on cotton dust exposure was also evaluated. Although the difference in prevalence of abnormal pulmonary function between the first (38.5%) and second study (38.9%) was not statistically significant, smokers had significantly higher frequency than nonsmokers in both surveys. A significant trend existed between the cotton dust levels and the frequency of abnormal lung function. The significant trend was also noted in both smokers and nonsmokers. The frequency of respiratory symptoms and the prevalence of severe byssinosis in the second survey (14.9% and 12.6%, respectively) were significantly lower than that in the first survey (39.7% and 21.9%, respectively). The reduction of symptoms was due to remodeling of this old cotton mill. The prevalences of respiratory symptoms and byssinosis in smokers being significantly higher than in nonsmokers only found in the first survey, but not found in the second survey. These results indicate that smoking potentiates the effect of cotton dust exposure on respiratory symptoms and byssinosis. The second study reveals high prevalence of byssinosis still existed in Taiwanese cotton mill, although the prevalence was declining. Smoking was found to show an additive effect on cotton dust exposure. Anti-smoking campaign, occupational health program to reduce the dust exposure, and periodical medical examination are measures to prevent from byssinosis.

We initiated an investigation to examine the possible association between the cancer risk and the chlorinated organic solvents exposure in an electronic factory. To obtain information on the incidence of the various types of cancer among the exposed and comparison groups, the cohort populations were merged with the National Mortality Database, the National Cancer Registry Database, and the National Insurance Hospitalization Database from the Department of Health (DOH), as well as the Labor Insurance Hospitalization Database from the Bureau of Labor Insurance (BLI). The proportionate cancer morbidity ratio (PCMR) was used to estimate the cancer risk of the exposed workers in comparison with either textile workers or electronics workers. After adjustment for age, only the PCMR for breast cancer in the exposed female employees was significantly elevated when compared with the two comparison groups. The increased risk of breast cancer was mainly found in the category of 1989-1997 for year of diagnosis when stratified by calendar year. However, there was no dose-response relationship between female breast cancer risk and duration of employment. Although some PCMRs for the cancers were also increased in the exposed group, female breast cancer was consistently increased when compared with both textile and electronics comparison groups using different exclusion criteria. The results obtained in the present study suggest a possible association between exposure to chlorinated organic solvents and female breast cancer. Since this association has never been reported in the previous studies, further study is needed to clarify the association.

The male cotton textile workers were healthier than the general population. The healthy-worker effect may be one of the causes, in general workers in industry have a better mortality patterns than those not working.
