Occupational Exposure to Trichloroethylene and Cancer Risk for Workers at the Paducah Gaseous Diffusion PlantBahr, Debra E., Aldrich, Timothy E., Seidu, Dazar, Brion, Gail M., Tollerud, David J. 01 January 2011 (has links)
Objective: The Paducah Gaseous Diffusion Plant (PGDP) became operational in 1952; it is located in the western part of Kentucky. We conducted a mortality study for adverse health effects that workers may have suffered while working at the plant, including exposures to chemicals. Materials and Methods: We studied a cohort of 6820 workers at the PGDP for the period 1953 to 2003; there were a total of 1672 deaths to cohort members. Trichloroethylene (TCE) is a specific concern for this workforce; exposure to TCE occurred primarily in departments that clean the process equipment. The Life Table Analysis System (LTAS) program developed by NIOSH was used to calculate the standardized mortality ratios for the worker cohort and standardized rate ratio relative to exposure to TCE (the U.S. population is the referent for age-adjustment). LTAS calculated a significantly low overall SMR for these workers of 0.76 (95% CI: 0.72-0.79). A further review of three major cancers of interest to Kentucky produced significantly low SMR for trachea, bronchus, lung cancer (0.75, 95% CI: 0.72-0.79) and high SMR for Non-Hodgkin's lymphoma (NHL) (1.49, 95% CI: 1.02-2.10). Results: No significant SMR was observed for leukemia and no significant SRRs were observed for any disease. Both the leukemia and lung cancer results were examined and determined to refect regional mortality patterns. However, the Non-Hodgkin's Lymphoma finding suggests a curious amplification when living cases are included with the mortality experience. Conclusions: Further examination is recommended of this recurrent finding from all three U.S. Gaseous Diffusion plants.

Risques professionnels dans l'asthme / Occupational risk factors in asthmaDumas Milne Edwards, Orianne 05 December 2012 (has links)
L’importance des facteurs de risque professionnels dans l’asthme est bien établie, mais le rôle de certains agents doit être clarifié. Les objectifs de la thèse sont d’évaluer les liens entre les expositions aux produits de nettoyage et l’asthme, et d’étudier l’impact et la prise en compte du biais du travailleur sain, dans l’étude Epidémiologique des facteurs Génétiques et Environnementaux de l’Asthme (EGEA, 2047 sujets dont 1477 adultes avec des données professionnelles). L’exposition aux produits de nettoyage a été estimée par une expertise et une matrice emploi-exposition. Chez les femmes, l’asthme actuel était associé à l’exposition aux détartrants (OR=2.4 (1.1-5.3)), et aux sprays (2.9 (1.0-8.1)) et à l’ammoniac (3.1 (1.2-7.8)) chez les aides-soignantes. Les détartrants et l’ammoniac sont des irritants. L’exposition aux produits de nettoyage était associée à l’asthme sévère et sans sensibilisation allergique. Deux analyses ont souligné l’importance du biais du travailleur sain dans l’asthme. Un biais de sélection à l’embauche a été observé chez des sujets avec un asthme sévère dans l’enfance. Un modèle marginal structural a permis de prendre en compte le biais du travailleur sain dans l’étude de l’effet des expositions professionnelles sur l’expression clinique de l’asthme au cours de la vie. En plus du rôle d’asthmogènes connus, le rôle d’agents moins bien établis, comprenant des irritants (1.6 (1.0-2.4)) était suggéré. Les résultats sont cohérents avec un rôle des irritants dans l’asthme lié au travail. Ils soutiennent une utilisation plus large d’approches d’analyse causale pour contrôler le biais du travailleur sain dans les études des risques professionnels. / It is well-recognized that workplace exposures importantly contribute to the burden of asthma, but the role of some agents needs to be clarified. The aims of the thesis are to evaluate the relationships between occupational exposure to cleaning products and asthma, and to study the impact and the control of the healthy worker effect bias, in the Epidemiological study on the Genetics and Environment of Asthma (EGEA, 2047 subjects including 1477 adults with data regarding occupations).Exposure to cleaning products was estimated by an expert assessment and a job-exposure matrix. In women, current asthma was associated with exposure to decalcifiers (OR=2.4 (1.1-5.3)), and to sprays (2.9 (1.0-8.1)) and ammonia (3.1 (1.2-7.8)) in personal care workers. Decalcifiers and ammonia are irritants. Exposure to cleaning products was associated with severe asthma, and asthma without allergic sensitization. Two analyses underlined the important impact of the healthy worker effect in asthma. A healthy worker hire effect was observed in subjects with severe asthma in childhood. Using a marginal structural model, we studied the effect of occupational exposure on asthma clinical expression over a lifetime, while controlling for the healthy worker effect bias. Elevated risks of asthma were observed, not only for known asthmagens, but also for other agents which role in asthma is less established, including irritants (1.6 (1.0-2.4)). The results are consistent with a role of irritants in work-related asthma. They support a broader use of causal inference approaches, to control the healthy worker effect bias in studies of occupational risk factors.

Sociálně ekonomické a prostorové determinanty výskytu nemocí z povolání v automobilovém průmyslu v Česku / Socioeconomic and Spatial Determinants of Occupational Diseases in the Automotive Industry in CzechiaJarolímek, Jan January 2017 (has links)
Health and reducing disparities in health between and within countries are among the principal global sustainable development objectives for the period 2016-2030. The incidence of Occupational Diseases (OD) is characterized by very distinct differentiation, both regional and sectoral, and has considerable dynamics in time and place. Given that Czechia is at the top among all EU member states in terms of employment in the automotive industry and production of new vehicles, new research on OD in the automotive industry acquires importance. The Ph.D. Thesis is conceived as an ecological correlation study focusing on the study of the determinants of OD in automotive industry. Its own core work is to analyze 32,646 cases of OD (in the past 20 years) and a set of data from a survey of 247 companies of the automotive industry (employing nearly 110,000 employees, i.e. 78 % of the economically active population working in this sector). In the present work are used available data from routine statistics, data from registers and basic sanitation data from a questionnaire survey. The study innovatively links research of Global production networks and medical-geographical approach. At the end of the Ph.D. Thesis, specific outcomes for praxis and discusses possible topics for further research in this area are...
