RESUMO
OBJECTIVES: Etiological factors of testicular germ cell tumors (TGCT) remain largely unknown, but a causal role of occupational exposures to solvents has been suggested. Previous studies analyzing these exposures reported discordant results, potentially related to exposure assessment methods. The aim of this study was to investigate the role of occupational exposure to solvents on the risk of developing TGCT among young men. METHODS: This study examined occupational exposures to solvents and TGCT risk based on the lifetime work histories of 454 cases and 670 controls, aged 18-45 years, of the French national TESTIS case-control study. Solvent exposure was estimated using: (i) exposure assignment by job-exposure matrix (JEM) and (ii) JEM combined with self-reported exposure data from specific questionnaires (SQ) and expert assessment (EA). Odds ratios (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression models. RESULTS: Both approaches (JEM and JEM+SQ+EA) showed a consistent association between TGCT and trichloroethylene exposure (exposed versus not exposed; JEM=OR 1.80 [95% confidence interval (CI) 1.12-2.90] and JEM+SQ+EA= OR 2.59 (95% CI 1.42-4.72). Both approaches also observed positive associations with ketone esters and fuels & petroleum-based solvents. CONCLUSION: The results suggest that some organic solvents might be involved in the pathogenesis of TGCT among occupationally exposed men. The combined use of JEM+SQ+EA seemed to limit misclassification by considering individual exposure variability and is, therefore, an appealing approach to assess occupational exposures in epidemiological studies.

OBJECTIVES: This study aims to present an overview of the formal recognition of COVID-19 as occupational disease (OD) or injury (OI) across Europe. METHODS: A COVID-19 questionnaire was designed by a task group within COST-funded OMEGA-NET and sent to occupational health experts of 37 countries in WHO European region, with a last update in April 2022. RESULTS: The questionnaire was filled out by experts from 35 countries. There are large differences between national systems regarding the recognition of OD and OI: 40% of countries have a list system, 57% a mixed system and one country an open system. In most countries, COVID-19 can be recognised as an OD (57%). In four countries, COVID-19 can be recognised as OI (11%) and in seven countries as either OD or OI (20%). In two countries, there is no recognition possible to date. Thirty-two countries (91%) recognise COVID-19 as OD/OI among healthcare workers. Working in certain jobs is considered proof of occupational exposure in 25 countries, contact with a colleague with confirmed infection in 19 countries, and contact with clients with confirmed infection in 21 countries. In most countries (57%), a positive PCR test is considered proof of disease. The three most common compensation benefits for COVID-19 as OI/OD are disability pension, treatment and rehabilitation. Long COVID is included in 26 countries. CONCLUSIONS: COVID-19 can be recognised as OD or OI in 94% of the European countries completing this survey, across different social security and embedded occupational health systems.

Background: Testicular germ cell tumors (TGCT) are the most frequent cancer in young men in developed countries. Parental occupational exposures during early-life periods are suspected to increase TGCT risk. The objective was to estimate the association between parental occupations at birth and adult TGCT. Methods: A case-control study was conducted, including 454 TGCT cases aged 18-45 from 20 French university hospitals, matched to 670 controls based on region and year of birth. Data collected from participants included parental jobs at birth coded according to the International Standard Classification of Occupation-1968 and the French nomenclature of activities-1999. Odds ratios (OR) for TGCT and 95% confidence intervals (CI) were estimated using conditional logistic regression, adjusting for TGCT risk factors. Results: Paternal jobs at birth as service workers (OR = 1.98, CI 1.18-3.30), protective service workers (OR = 2.40, CI 1.20-4.81), transport equipment operators (OR = 1.96, CI 1.14-3.37), specialized farmers (OR = 2.66, CI 1.03-6.90), and maternal jobs as secondary education teachers (OR = 2.27, CI 1.09-4.76) or in secondary education (OR = 2.35, CI 1.13-4.88) were significantly associated with adult TGCT. The risk of seminoma was increased for the above-mentioned paternal jobs and that of non-seminomas for public administration and defence; compulsory social security (OR = 1.99, CI 1.09-3.65); general, economic, and social administration (OR = 3.21, CI 1.23-8.39) for fathers; and secondary education teacher (OR = 4.67, CI 1.87-11.67) and secondary education (OR = 3.50, CI 1.36-9.01) for mothers. Conclusion: Some paternal jobs, such as service workers, transport equipment operators, or specialized farmers, and maternal jobs in secondary education seem to be associated with an increased risk of TGCT with specific features depending on the histological type. These data allow hypotheses to be put forward for further studies as to the involvement of occupational exposures in the risk of developing TGCT, such as exposure to pesticides, solvents, or heavy metals.

OBJECTIVES: To assess the mental health and working constraints perception of first-year PhD in France. DESIGN: It is a cross-sectional study. SETTING: The study was conducted by the team of the Lyon 1 University's Occupational Health and Medical Service for Staff, from October 2019 to February 2020. First-year PhD students employed by the university were seen during the routine occupational health medical check-up. PARTICIPANTS: A total of 161 PhD students in science from the 2019 intake were included in the study (participation rate 98%). OUTCOME MEASURES: Data were collected using a self-questionnaire on psychosocial constraints at work (Job Content Questionnaire), the quality of the professional relationship with the supervisor (Advisory Working Alliance Inventory, Student perspective (AWAI-S)), medical conditions, anxiety (Generalized Anxiety Disorder-7) and depressive symptoms (Patient Health Questionnaire-9). RESULTS: A total of 161 PhD students from the 2019 intake were included in the study (participation rate 98%). Most of the PhD students reported high psychological demands (58%), high decision latitude (53%), high social support (55%) and good professional relationships with their supervisor (mean of global score of AWAI-S=114.5). However, 34% showed signs of at least mild depression, 19% showed signs of anxiety and 20% were referred to a mental health professional after the survey. Bivariate analyses showed that history of psychiatric disorders, their relationship with their supervisor, having complementary teaching activities and stressful working conditions contributed to anxiety and depression. CONCLUSIONS: Even in the first year of their PhD, some students had mental health issues. It seems relevant to generalise the medical follow-up of all PhD students as soon as they enter the doctoral programme in order to detect and treat their health problems and psychological disorders at an early stage.

Road risks (commuting and on-duty accidents) have been responsible for 44% of work-related fatalities compensated by the French system of Social Security in 2012 and still represented 37% in 2018. Our objective was to assess risk factors for commuting accidents among the non-physician staff in a French university hospital. We conducted a case-control study of commuting accidents from 2012 to 2016. Cases were identified and controls were randomly selected from the hospital's personnel file with matches by year of the accident, gender and age. Risk factors were assessed using conditional logistic regression analysis. An increased risk was observed for 2 × 8 hour shifts, crude OR = 1.40 (95% CI = 1.05-1.86) compared to daytime schedules, but not confirmed in the multiple model. Being a duty officer and not working the day before the accident were associated with increased risk of accidents with adjusted OR = 1.9 (95% CI = 1.1; 3.3) and OR = 1.5, (95% CI = 1.1; 2.1), respectively. The risk increased as the distance between home and work increased, such as adjusted OR = 2.2 (95% CI = 1.4; 3.4) for a distance of >3.6 to 9 km, OR = 2.6, (95% CI = 1.7; 4.0) for a distance of >9 km to 19 km, and OR = 4.2, (95% CI = 2.8; 6.2) for >19 km vs. <3.6 km. The distance between home and work, not working the day before the accident, and certain categories of personnel were related to commuting accidents.

Background: Our study examined the social disparities that exist in the implementation of protection measures for occupational exposure to carcinogenic, mutagenic and reprotoxic agents in France, and its aim was to identify which types of employees/jobs require priority action. Methods: We analyzed data from the 2010 French national cross-sectional survey of occupational hazards. The availability of the various collective and individual protections was explored. The associations of job and company characteristics with protective measures were studied by multilevel regressions. Results: Effective collective protection measures were implemented in 25% of the exposure situations. Managers and intellectual professionals, who accumulated lower CMR exposure prevalences, durations, and intensities than blue-collar workers, benefited the most from effective collective protections. The availability of effective collective protection measures was not influenced by the size of the company. The presence of a Committee for health, safety, and work conditions, as well as intervention of occupational health and safety officers in the past 12 months were associated with a lower exposure intensity, but not with the implementation of more protection measures. Longer exposure durations were associated with more effective collective protection. Conclusion: Substantial discrepancies were observed in exposure levels and protection measures as a function of the characteristics of employees' jobs and the companies that they work for. The main priority in regard to prevention should be a focus on unskilled workers, since their collective protection still appears to be insufficient, while their exposure lengths and intensities were the most substantial.

Occupational lung cancers are under-reported and under-compensated worldwide. We assessed systematic screening for occupational exposure to carcinogens combining a self-administered questionnaire and an occupational consultation to improve the detection of occupational lung cancers and their compensation. Social deprivation and the costs of this investigation were estimated. Patients with lung cancer received a self-administered questionnaire to collect their job history, potential exposure to carcinogens and deprivation. A physician assessed the questionnaire and recommended an occupational consultation if necessary. During the consultation, a physician assessed if the lung cancer was work-related and, if it was, delivered a medical certificate to claim for compensation. Over 18 months, 440 patients received the self-administered questionnaire: 234 returned a completed questionnaire and a consultation was required for 120 patients. Compensation was judged possible for 41 patients. Among the 35 medical certificates delivered, 19 patients received compensation. Nearly half the patients (46%) were assessed as socially deprived and these patients took significantly longer to return the questionnaire compared with those who were not deprived. The mean cost of the process was 62.65 per patient. Our results showed a systematic self-administered questionnaire can be used to identify patients potentially exposed to carcinogens and to improve compensation.

PURPOSE: The proportion of lung cancers with an occupational origin has been estimated to be between 10 and 20%. They are largely under-reported, as 60% are not compensated as occupational disease. Although most patients are not familiar with the process of compensation, other factors could explain this under-reporting. The aim of this study was to identify psychosocial factors that could impact patients with occupational lung cancer to claim for compensation. METHODS: We conducted a case study involving semi-structured interviews with eight lung cancer patients enrolled in a cohort designed to systematically screen occupational exposures and propose claims for compensation to work-related cancer patients. RESULTS: Seven interviewed patients were familiar with occupational cancers, but most of them did not believe that past exposure could be related to their current disease. Patients associated compensation claims with a long and complex procedure for an abstract purpose. Several patients expressed a certain attachment to their employers. CONCLUSION: Interviewed patients often considered compensation claims to be a grievance procedure against the employers whom they did not consider to be responsible for their disease. Lung cancer is itself an obstacle to compensation considering the aggressive treatments and related adverse events, the poor medium-term prognosis and the predominant role of smoking in the etiology of the disease. Patients mentioned the financial compensation and the role of healthcare professionals as key elements to motivate them to claim for compensation.

Ten to 29% of lung cancers might be linked to occupational factors but 60% of them are not compensated. The PROPOUMON project aimed to improve the identification, recognition and compensation of occupational lung cancer as occupational disease using a self-administered questionnaire (AQREP). One objective was to assess the AQREP, comparing it with the questionnaire drawn up by the French Language Pneumology Society (Q-SPLF). From March 2014 to September 2015, 90 lung cancer patients treated at the Centre Léon-Bérard responded to the AQREP and Q-SPLF. The two physicians in charge of the consultation assessed independently whether or not a consultation was indicated. A certificate for the compensation process was proposed when a suspicion of high or average imputability was identified. Analysis of the questionnaires was concordant for 73% of the patients. The AQREP has a sensitivity of 72% and a specificity of 73%. Its positive and negative predictive values were 62 and 82%. The information provided by 24 patients were discordant between questionnaires. In two patients with discordant evaluation (AQREP+/Q-SPLF-; AQREP-/Q-SPLF+), one Initial Medical Certificate (IMC) was written. This study made it possible to conclude that AQREP is relevant for the identification of potentially occupational lung cancers. Collegial discussion of complex cases might be considered. The project is currently been extended to other centers and to lymphoma.

Background: To explore trends in social and occupational inequalities in terms of exposure to carcinogenic, mutagenic and reprotoxic chemicals (CMR) for French employees. Our study assessed data from the French national cross-sectional survey of occupational hazards (SUMER) that was conducted in 2003 and 2010. We included all of the 27 CMR agents that were classified by the International Agency for Research on Cancer or European Union regulations as being known or presumed to have CMR potential in humans. Trends in prevalence and degree of exposure were examined using multilevel logistic regression analysis. The number of employees exposed to CMR agents decreased by 17.5% between 2003 and 2010. The only CMR entities for which exposure rates increased are not considered to be proven CMRs according to the European Union regulations. With the exception of apprentices, there was an overall decrease in exposure prevalence for all employees. This decrease occurred, however, to different extents. The decrease in the risk of exposure to CMR agents was much greater for those on permanent contracts, managers, and in enterprises with more than 500 employees. Nonetheless, in situations where there was potential for exposure, companies with fewer than 10 employees were in fact able to decrease the degree of risk more than the others. Our results confirm the relevance of reinforcing regulatory restrictions for CMR products, while also indicating that monitoring of trends in disparities will allow public health policy makers to better evaluate progress made toward reducing disparities that affect vulnerable populations.

PURPOSE: To explore varied exposure to carcinogenic, mutagenic, and reprotoxic chemicals (CMR) for French employees. METHODS: Our study assessed data from the French national cross-sectional survey of occupational risks (SUMER) that was conducted in 2010 in a national representative sample of employees. We selected 28 CMR agents that were classified by the International Agency for Research on Cancer or European Union as being known or presumed to have CMR potential in humans. The association of individual and job characteristics with exposure prevalence, duration, and intensity of the CMR agents during a 1-week period was examined using multilevel logistic regression analysis. RESULTS: Overall, 10.4% of employees in 2010 were exposed to one or more CMR agents at their workplace, and 3.4% were subjected to multiple CMR exposures. Blue-collar workers, night-shift workers and workers with short-term employment contracts experienced higher exposure prevalence (p < 0.01) and intensity (p < 0.05). Blue-collar workers and shift workers experienced also longer exposure duration (p < 0.001). Conversely, managers, workers of large companies, and women were less exposed to CMR agents (p < 0.001). The presence of a Committee for Health, Safety, and Working Conditions, and intervention by Occupational Health and Safety officers were significantly associated with reduced exposure intensities (p < 0.001 and p < 0.05). Establishment of European CMR regulations and the existence of an applicable substitution principle reduced the exposure duration (p < 0.001) and intensity (p < 0.05). CONCLUSIONS: Our results point out disparities in CMR exposure and identify high-priority targets for prevention measures to help reducing social health discrepancies.

INTRODUCTION: An analysis of the occupational constraints and exposures to which employees facing road risk at work are subject was performed, with comparison versus non-exposed employees. Objective was to improve knowledge of the characteristics of workers exposed to road risk in France and of the concomitant occupational constraints. The descriptive study was based on data from the 2010 SUMER survey (Medical Monitoring of Occupational Risk Exposure: Surveillance Médicale des Expositions aux Risques professionnels), which included data not only on road risk exposure at work but also on a range of socio-occupational factors and working conditions. MATERIALS AND METHODS: The main variable of interest was "driving (car, truck, bus, coach, etc.) on public thoroughfares" for work (during the last week of work). This was a dichotomous "Yes/No" variable, distinguishing employees who drove for work; it also comprised 4-step weekly exposure duration: <2h, 2-10h, 10-20h and ≥20h. RESULTS: 75% of the employees with driving exposure were male. Certain socio-occupational categories were found significantly more frequently: professional drivers (INSEE occupations and socio-occupational categories (PCS) 64), skilled workers (PCS 61), intermediate professions and teaching, health, civil service (functionaries) and assimilated (PCS 46) and company executives (PCS 36). Employees with driving exposure more often worked in small businesses or establishments. Constraints in terms of schedule and work-time were more frequent in employees with driving exposure. Constraints in terms of work rhythm were more frequent in non-exposed employees, with the exception of external demands requiring immediate response. On the Karasek's Job Demand-Control Model, employees with driving exposure less often had low decision latitude. Prevalence of job-strain was also lower, as was prevalence of "iso-strain" (combination of job-strain and social isolation). Employees with driving exposure were less often concerned by hostile behavior and, when they did report such psychological violence (inspired on the Leymann questionnaire), it was significantly more frequently due to clients, users or patients. DISCUSSION: Employees with driving exposure at work showed several specificities. The present study, based on a representative nationwide survey of employees, confirmed the existence of differences in working conditions between employees with and without driving exposure at work. In employees with driving exposure, constraints in terms of work-time and rhythm increased with weekly exposure duration, as did tension at work and exposure to hostile behavior.

Despite the rising number of lung cancers recognized as occupational disease, occupational lung cancers are still under-reported. To improve the recognition of occupational lung cancer, we implemented at the Léon-Bérard Cancer Centre, a questionnaire-based process to identify occupational exposures in these patients and improve compensation. Between January 2010 and December 2011, 91 lung cancer patients responded to a questionnaire. An "occupational cancer" consultation was proposed to patients reporting exposure to carcinogens or jobs with risk of exposure. Fifty-one patients were seen in consultation (34 following the questionnaire and 17 directly addressed by the oncologist). A suspicion of high or average imputability was identified in 31 (60.8%) patients and a compensation process seemed possible for 27 (61.4%). Asbestos was the most common carcinogen identified. Among 17 compensation processes engaged, 12 succeeded and one is ongoing. The complexity of the administrative process seems to be an obstacle for patients and perpetuates inequality. The implementation of our approach increased the identification and the compensation of occupational lung cancer. Our approach responds to the objectives of the National Cancer Plan and helps to improve the overall care of patients with cancer. This approach has been awarded by the national label in 2011 "Year of the patients and their rights".

A method for a semi-quantitative retrospective assessment of exposure to trichloroethylene (TCE) was implemented for a case-control study conducted in the Arve valley (France), an area with a widely developed screw-cutting industry, where teams of occupational physicians have collected a large quantity of well-documented measurements. A task-exposure matrix was developed to link the main working circumstances in a screw-cutting workshop to corresponding TCE-exposure levels: a 'basic level' was assigned to each task, standing for usual working procedures; exposure circumstances, such as duration or distance from the TCE source, were introduced as corrective factors. In parallel, a detailed occupational questionnaire was designed, setting subjects' descriptions of their successive jobs and working circumstances against levels assessed in the matrix. Possible exposure to TCE, plus some other occupational compounds (other solvents, oils, some metals, asbestos, welding fumes and ionizing radiations), were assessed for any job in all job histories. An average level of exposure to TCE, related to an 8 h usual working day, was attributed to each job period in turn, which was then categorized into six classes: 0; 1-35; 35-50; 50-75; 75-100; and >100 p.p.m. A total of 402 study subjects described their occupational life (average 3.7 jobs/subject, from 1924 to 2003). About 19% of the 1486 job periods described were assessed as being exposed to TCE; of these, 72.2% involved levels<35 p.p.m., 13.2% involved levels>50 p.p.m. and 5.4% above the French occupational exposure limit of 75 p.p.m. (TWA 8 h). A total of 41 job periods included exposure with peaks. Compared with levels encountered in other studies, the more severely exposed part of our study population seemed more exposed than most other populations previously studied, owing to vapor degreasing practices.
