Cleaning at Home and at Work in Relation to Lung Function Decline and Airway Obstruction
Rationale: Cleaning tasks may imply exposure to chemical agents with potential harmful effects to the respiratory system, and increased risk of asthma and respiratory symptoms among professional cleaners and in persons cleaning at home has been reported. Long-term consequences of cleaning agents on respiratory health are, however, not well described. Objectives: This study aimed to investigate long-term effects of occupational cleaning and cleaning at home on lung function decline and airway obstruction. Methods: The European Community Respiratory Health Survey (ECRHS) investigated a multicenter...
Association of Parkinson’s disease with industry sectors
A French nationwide incidence study In order to identify working environments at risk for Parkinson's disease (PD), we investigated the relation between the importance of industry sectors, used as a surrogate for occupational exposures, and PD incidence in French cantons. The number of incident PD cases (2010–2014) in 3689 cantons of metropolitan France was determined using drug claims from French National Health Insurance databases. The proportions of workers in 38 industry sectors in 2006 were calculated for each canton. Associations between the proportions of workers in industry sectors...
Case-control investigation of occupational exposure to chlorinated solvents and non-Hodgkin’s lymphoma
Objectives: Although many studies have investigated the association between trichloroethylene (TCE) exposure and non-Hodgkin's lymphoma (NHL), less is known about other chlorinated solvents. We extended our previous analysis of occupational TCE exposure in a multicentre population-based case-control study of NHL to investigate associations with five additional chlorinated solvents: 1,1,1,-trichloroethane, carbon tetrachloride, chloroform, methylene chloride and perchloroethylene. Methods: Cases (n=1189) and controls (n=982) provided detailed information on their occupational histories and workplace...
Types and Health Hazards of Fibrous Materials Used as Asbestos Substitutes
The World Health Organization (WHO) estimates that about 125 million people are exposed to asbestos at worksites around the world, and more than 107,000 people die of asbestos-related diseases, including lung cancer, mesothelioma, or asbestosis, due to occupational exposure to asbestos. Substitute materials have been studied and developed for a long time because of the hazards of asbestos, and many people have recently shown interests in the hazards of substitute materials. Fibrous materials may be considered as an alternative to asbestos. There are many kinds of fiber materials, which can be largely...
Work history and radioprotection practices in relation to cancer incidence and mortality in US radiologic technologists performing nuclear medicine procedures
Introduction: Technologists working in nuclear medicine (NM) are exposed to higher radiation doses than most other occupationally exposed populations. The aim of this study was to estimate the risk of cancer in NM technologists in relation to work history, procedures performed and radioprotection practices. Methods: From the US Radiologic Technologists cohort study, 72 755 radiologic technologists who completed a 2003–2005 questionnaire were followed for cancer mortality through 31 December 2012 and for cancer incidence through completion of a questionnaire in 2012–2013. Multivariable...
Interventions for preventing occupational irritant hand dermatitis
Background: Occupational irritant hand dermatitis (OIHD) causes significant functional impairment, disruption of work, and discomfort in the working population. Different preventive measures such as protective gloves, barrier creams and moisturisers can be used, but it is not clear how effective these are. This is an update of a Cochrane review which was previously published in 2010. Objectives: To assess the effects of primary preventive interventions and strategies (physical and behavioural) for preventing OIHD in healthy people (who have no hand dermatitis) who work in occupations where the...
Soignants et médicaments cytotoxiques
Place de la biométrologie dans la maîtrise des risques dans le temps Les médicaments cytotoxiques utilisés dans les traitements des cancers présentent une toxicité intrinsèque, du fait de leurs propriétés génotoxiques, tératogènes et cancérigènes. Les professionnels de santé pouvant y être exposés, il est essentiel de garantir leur sécurité et de mettre en place des programmes d'évaluation des expositions pour documenter les expositions, juger de l'efficacité...
Expositions aux champs électromagnétiques
Repères en santé au travail Omniprésents dans l'environnement quotidien et en milieu de travail, les champs électromagnétiques (CEM) suscitent des interrogations et parfois des inquiétudes quant aux risques qu'ils peuvent faire encourir aux personnes. Si les effets biophysiques avérés sur l'homme sont bien connus, il reste parfois difficile pour un non spécialiste de faire la part des choses entre les effets tels qu'ils peuvent être rapportés par les travailleurs et leur relation avec la présence...
Burden of lung cancer attributable to occupational diesel engine exhaust exposure in Canada
Objective: To estimate the population attributable fraction (PAF) and number of incident and fatal lung cancers in Canada from occupational exposure to diesel engine exhaust (DEE). Methods: DEE exposure prevalence and level estimates were used with Canadian Census and Labour Force Survey data to model the exposed population across the risk exposure period (REP, 1961–2001). Relative risks of lung cancer were calculated based on a meta-regression selected from the literature. PAFs were calculated using Levin's equation and applied to the 2011 lung cancer statistics obtained from the Canadian...

Prostate cancer surveillance by occupation and industry: the Canadian Census Health and Environment Cohort (CanCHEC)
As there are no well-established modifiable risk factors for prostate cancer, further evidence is needed on possible factors such as occupation. Our study uses one of the largest Canadian worker cohorts to examine occupation, industry, and prostate cancer and to assess patterns of prostate cancer rates. The Canadian Census Health and Environment Cohort (CanCHEC) was established by linking the 1991 Canadian Census Cohort to the Canadian Cancer Database (1969–2010), Canadian Mortality Database (1991–2011), and Tax Summary Files (1981–2011). A total of 37,695 prostate cancer cases...

Chez les femmes, les mésothéliomes sont les maladies reliées à l'exposition à l'amiante les plus fréquentes, alors que chez les hommes ce sont les amiantoses qui prédominent. Près de 60 % des cas d'amiantose, près de 50 % des cas de...
Progressive Massive Fibrosis in Coal Miners From 3 Clinics in Virginia
Since 1970, the Coal Workers' Health Surveillance Program (CWHSP), administered by the National Institute for Occupational Safety and Health, has offered periodic chest radiographs to working US coal miners.1 The primary purpose of the CWHSP is early detection of coal workers' pneumoconiosis to prevent progression to disabling lung disease, including progressive massive fibrosis (PMF). By the late 1990s, PMF was rarely identified among miners participating in the CWHSP. However, a 2014 report documented an increase in the prevalence of PMF in Appalachia.2 On February 1, 2017, the director...
Associations Between Disinfection By-Product Exposures and Craniofacial Birth Defects
Objective: The aim of this study was to examine associations between craniofacial birth defects (CFDs) and disinfection by-product (DBP) exposures, including the sum of four trihalomethanes (THM4) and five haloacetic acids (HAA5) (ie, DBP9). Methods: We calculated first trimester adjusted odds ratios (aORs) for different DBPs in a matched case–control study of 366 CFD cases in Massachusetts towns with complete 1999 to 2004 THM and HAA data. Results: We detected elevated aORs for cleft palate with DBP9 (highest quintile aOR = 3.52; 95% CI: 1.07, 11.60), HAA5, trichloroacetic acid (TCAA), and...
Occupational exposure to organic solvents and risk of male breast cancer
A European multicenter case-control study Objectives: The etiology of male breast cancer (MBC) is largely unknown but a causal role of exposure to organic solvents has been suggested. Previous studies on occupational risk factors of breast cancer were often restricted to women who are frequently exposed to lower levels and at a lower frequency than men. We investigated the association between MBC and occupational exposure to petroleum and oxygenated and chlorinated solvents in a multicenter case–control study of rare cancers in Europe. Methods: The study included 104 MBC cases and 1901 controls...
Conditions reliées à l’exposition au béryllium au Québec : 1999-2011
Les dossiers médicaux de 123 travailleurs ayant soumis une réclamation à la Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST) pour une condition reliée à l'exposition au béryllium entre le 1er janvier 1999 et le 31 décembre 2011 ont été analysés. Trois formes distinctes de conditions reliées au béryllium ont été étudiées, soit : la sensibilisation au béryllium, la bérylliose chronique asymptomatique...
Coal miner participation in a job transfer program designed to prevent progression of pneumoconiosis, United States, 1986–2016
The Part 90 program was designed to prevent progression of pneumoconiosis in U.S. coal miners by establishing their right to transfer to a less dusty job in the mine. We calculated the proportion of Part 90-eligible miners who participated during 1986–2016, examined participation by region, and compared characteristics of miners by participation status. Of the 3,547 eligible miners, 14.4% exercised their Part 90 option. Miners working in states outside central Appalachia, and those with more severe pneumoconiosis, were more likely to participate. The primary goal of respiratory health surveillance...

Pour les neuf cas signalés, l'investigation a porté sur i) l'identification des cas, ii) la reconstitution des parcours et expositions professionnels au sein du laboratoire, iii) une recherche bibliographique des caractéristiques épidémiologiques...
Exposure to substances hazardous to health in foundries
Tackling the causes of occupational lung disease is a key priority for HSE. Foundry workers are potentially exposed to a wide range of hazardous substances, including, for example, respirable crystalline silica (RCS), metal fumes and dust, that can cause lung (and other) cancers and chronic obstructive pulmonary disease (COPD). This work was undertaken to understand current exposures to hazardous substances in the foundry industry, to identify examples of good control practice, and to establish benchmark standards of control for the industry. Many examples of good practice were found, which, if...

Respiratory Symptoms in Hospital Cleaning Staff Exposed to a Product Containing Hydrogen Peroxide, Peracetic Acid, and Acetic Acid
Cleaning and disinfecting products consisting of a mixture of hydrogen peroxide (HP), peracetic acid (PAA), and acetic acid (AA) are widely used as sporicidal agents in health care, childcare, agricultural, food service, and food production industries. HP and PAA are strong oxidants and their mixture is a recognized asthmagen. However, few exposure assessment studies to date have measured HP, PAA, and AA in a health care setting. In 2015, we performed a health and exposure assessment at a hospital where a new sporicidal product, consisting of HP, PAA, and AA was introduced 16 months prior. We collected...
