Predictors of the return to work for pregnant employees on preventive leave: Patients from an occupational medicine consultation in Switzerland.

According to the Swiss legislation on maternity protection in the workplace (OProMa), if pregnant workers are exposed to occupational hazards and no protective measures are taken, a gynecologist will prescribe a certificate of preventive leave and the women must stop working. Returning to work is only possible if job adjustments are made. This study aims to evaluate the burden of absences on companies and to examine the predictors of the return to work for pregnant workers on preventive leave, by examining both the probability of return to work and the time required to return to work. The study sample includes data on 258 workplaces of pregnant workers on preventive leave, collected during an occupational medicine consultation aimed at supporting the implementation of the OProMa. Information is available on the worker (age, date of consultation), the hazards to which she is exposed, the company's knowledge of the OProMa and whether a risk analysis exists. Descriptive statistics and multivariate regression analysis are carried out. In 58% of the workplaces, it was not possible to return to work before the end of the pregnancy. This corresponds to an average absence of 4.5 months. In 42% of the workplaces, a return to work was possible thanks to workplace adaptations. A conforming risk analysis and a full knowledge of the OProMa for companies, and an early visit to the occupational medicine consultation for workers are good predictors of the likelihood of returning to work. Younger age and exposure to certain types of risks are factors that influence the duration of preventive leave. The implementation of OProMa in Switzerland poses serious challenges, but early identification of occupational hazards and practices that anticipate compliance with the law in the company increase the return to work in safety for pregnant workers.

[Patients experiencing burnout : medico-social needs and resources]. / Patients en situation de burnout : besoins médico-sociaux et ressources.

There is a gap between the current service offer and the needs of people suffering from burnout. Actors in the field, from employers to prescribers, have a role to play in addressing the health needs of the target population, promoting existing services and facilitating their integrative collaboration. This is what a study evaluating the adequacy between the health needs of people experiencing burnout and the services offered to these patients from the point of view of key informants in the canton of Vaud has shown. The first part identified, through empirical research on the Internet, services focused on work organization, therapeutic, social and professional reintegration services. The second part, based on a qualitative focus group method, identified 21 unmet needs.

Il existe un écart entre l'offre de services actuelle et les besoins des personnes en situation de burnout. Les acteurs de terrain, des employeurs aux prescripteurs, ont un rôle à jouer pour répondre aux besoins de santé de la population cible, promouvoir les services existants et faciliter leur collaboration intégrative. C'est ce qu'une étude évaluant l'adéquation entre les besoins de santé des personnes en situation d'épuisement professionnel ou de burnout et les services offerts à ces patients, du point de vue des informateurs clés du canton de Vaud, a démontré. Une première partie a identifié, par une recherche empirique sur internet, les services axés sur l'organisation du travail, les services thérapeutiques, sociaux et de réinsertion professionnelle. La seconde partie, basée sur une méthode qualitative par focus group, a identifié 21 besoins non comblés.

A narrative review on factors associated with job interruption during pregnancy.

Most women continue to work during pregnancy. However, some of them have to stop working before giving birth. Absence from work poses several challenges for employers and employees, as well as for society. The literature on absence from work during pregnancy and its determinants remains inconsistent and rather scarce. To conduct a narrative literature review on the factors associated with work interruption and on existing interventions aimed at reducing the absence prevalence during pregnancy. The review refers to published peer-reviewed articles dealing with all types of work interruption among pregnant women. Keyword searches were performed in the electronic databases PubMed, EMBASE, and Google Scholar, covering the period 2000-2022. The review, which includes 42 papers, presents a broad and comprehensive picture of factors and interventions associated with absence from work among pregnant workers. The factors appear at different levels and include factors related to the pregnant women, such as individual health and socio-demographic factors; employer and workplace-related factors, such as risk exposures and working conditions; factors related to the role of the healthcare provider; and factors related to the national context (social benefits/insurance). The determinants of absence from work during pregnancy are complex and multifactorial and involve multiple stakeholders. The discussion addresses gaps and needs in the literature on pregnancy at work and in the field of occupational health. Int J Occup Med Environ Health. 2023;36(3):303-23.

Evaluation of a pilot consultation for maternity protection at work in Switzerland.

STUDY AIMS: Switzerland's Labour Law and its Ordonnance on Maternity Protection aim to protect the health of pregnant employees and their unborn children while enabling them to continue to pursue their professional activities. Some companies encounter difficulties implementing the law's provisions. The Department of Occupational and Environmental Health, part of the Center for Primary Care and Public Health (Unisanté), has provided specialist occupational medicine consultations for pregnant employees since 2015. This study aimed to evaluate how well Swiss' maternity protection legislation is implemented by examining a list of relevant indicators measured during the occupational health consultation. The study also sought to investigate the consultation support provided to the relevant stakeholders and the adjustments made to pregnant employees' working conditions. METHODS: Descriptive variables and indicators relative to the application of the Swiss maternity protection legislation for 83 pregnant employees were collected during the consultation's pilot phase (between 2015 and 2016). Descriptive statistics and cross-analyses of these indicators were made. RESULTS: Most pregnant employees faced multiple exposures to occupational risks. Preventive risk analyses were rare. Few adjustments to workstations were proposed. We found a tendency for employees to leave their workstations early on in their pregnancies due to sick leave certificate prescriptions. Specialist consultation and collaboration with occupational health physicians to recommend interventions for pregnant employees can provide significant benefits and help some pregnant women to continue at their workstations with appropriate adjustments. DISCUSSION: A specialised occupational health consultation is a useful instrument for identifying occupational hazards for both the pregnant woman and her unborn child. It is also an opportunity to explain employers' legal responsibilities and obligations to safeguard the health of their pregnant employees and to give specific advice for their company's situation. This consultation also enables employers to maintain their employees' valuable professional competencies in the workplace for as long as possible. Finally, occupational health consultation helps and supports healthcare providers who must, according to the law, make decisions about whether pregnant employees can continue working safely or not.

[Protection of pregnant and breastfeeding workers in Switzerland: a practical guide]. / Protection des travailleuses enceintes et allaitantes en Suisse : guide pratique.

Specific working conditions may endanger pregnant women's and their children's health. Switzerland has specific legislation for the protection of pregnant and breastfeeding employees. However, the implementation of these provisions presents important shortcomings. Attending physicians or gynaecologists-obstetricians who care for pregnant women have a central role in controlling the efficacy of protective measures put in place for their patients at work. What are the occupational exposures at risk and their health impact ? What are the collaboration with the different actors involved in the protection of maternity at work ? What steps should be taken if occupational dangers are identified? What tools can be used ? This article answers and explore these questions.

Certaines conditions de travail peuvent nuire à la santé des femmes enceintes et de leurs enfants. La Suisse dispose d'une législation spécifique pour la protection des employées enceintes et allaitantes. Or, l'application de ces dispositions est lacunaire. Les médecins traitants ou les gynécologues-obstétriciens qui suivent des femmes enceintes ont un rôle central dans le contrôle d'efficacité des mesures de protection prises pour leurs patientes au travail. Quels sont les expositions professionnelles à risque et leur impact sanitaire ? Quelles sont les collaborations avec les différents acteurs impliqués dans la protection de la maternité au travail ? Quelles démarches entreprendre en cas d'identification de dangers ? Quels outils peuvent être utilisés ? Cet article permet de répondre à ces questions et de les approfondir.

[Occupational cancers: essentials for the general practioners]. / Cancers professionnels : l'essentiel pour le médecin au cabinet.

Given the frequency of cancers, prevention is based on knowledge of the causes. Experts estimate the proportion of cancers attributable to work at around 5 %. If it is shown that exposure at work is involved, the patient can claim compensation for an occupational disease. In order for the occupational origin to be identified, it is important to know which jobs/sectors of activity are possibly at risk. The aim of this article is to present the six main cancer sites for which a link with occupational exposure has been documented, to specify the causes of the under-reporting of occupational cancers, the role of the treating physician working in a multidisciplinary network, and the tools and practical advice for optimizing the support to patients/their relatives.

Face à la fréquence des cancers, la prévention repose sur la connaissance des étiologies. Des experts estiment la part des cancers attribuables au travail autour de 5 %. Si l'on démontre qu'une exposition au travail est en cause, le patient peut prétendre à une indemnisation en maladie professionnelle. Pour que l'origine professionnelle puisse être identifiée, il est important de savoir quels métiers/secteurs d'activité sont possiblement à risque. L'objectif de cet article est de présenter les 6 principaux sites de cancers pour lesquels un lien avec des expositions professionnelles est documenté, de préciser les causes de la sous-déclaration des cancers professionnels, le rôle du médecin traitant travaillant en réseau pluridisciplinaire, ainsi que les outils et les conseils pratiques pour optimiser l'accompagnement des patients/leurs proches.

[Occupational dermatoses: management for general practitioners and an interdisciplinary collaboration model]. / Dermatoses professionnelles : démarche diagnostique pluridisciplinaire et outil de dépistage au cabinet.

Dermatoses are among the most frequent diseases related to working conditions. Nevertheless, there is an under-reporting of occupational diseases and the management of patients with either a possible occupational dermatosis or a condition aggravated by work which could be improved. The aim of this article is to present the most common occupational dermatoses, a multidisciplinary diagnostic approach to them and to propose a screening tool for occupational exposures.

Les dermatoses sont parmi les maladies les plus fréquentes en lien avec les conditions de travail. Néanmoins, il existe une sous-déclaration en maladie professionnelle et la prise en charge des patients atteints, soit d'une possible dermatose professionnelle, soit d'une condition aggravée par le travail, qui pourrait être améliorée. L'objectif de cet article est de présenter les dermatoses professionnelles les plus communes et une démarche diagnostique pluridisciplinaire et de proposer un outil de dépistage des expositions professionnelles à risque.

Midwives and protection of pregnant workers in Western Switzerland: Practices, difficulties and contributions.

BACKGROUND: Switzerland's maternity protection legislation aims to protect the health of pregnant employees and their unborn children by regulating their potential occupational exposure to hazards and strenuous activities. This legislation provides a role for obstetricians, but not for midwives. AIMS: Identify the practices of Switzerland's French-speaking midwives that favour the implementation of maternity protection legislation and reflect on the profession's role in supporting pregnant employees. METHODS: 356 midwives answered an online questionnaire. The analysis focuses on the 205 midwives who perform pregnancy consultations in their practice. Data were analysed in two stages using STATA software: 1) simple descriptive and correlational statistics and 2) hierarchical cluster analysis to identify typologies of practices by grouping similar responses. FINDINGS: Despite having no officially defined role in Switzerland's maternity protection legislation, its midwives actively participate in protecting pregnant employees , especially those with more knowledge of the legislation, those with more years of experience and those practicing independently. The barriers that midwives face when trying to provide greater support for pregnant employees are linked significantly to their lack of knowledge about the legislation, a lack of recognition for their role in the current legislation and a lack of continuing education about the occupational health risks associated with pregnancy at work. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Their profession and specific practices give midwives privileged access to pregnant employees. Midwives' knowledge of the legislation, their awareness of the occupational risks and hazards facing pregnant employees and the conviction that their profession has the potential to make a difference could all be improved. The role of midwives should be-and deserves to be-formally and legally recognised and integrated into Switzerland's maternity protection legislation.

The role of the Swiss list of occupational diseases in the protection of workers' health.

Occupational disease lists (ODLs) are essential legal mechanisms for recognising pathologies related to exposure to occupational hazards. In 2017, Switzerland revised its ODL and solicited stakeholders to review the ODL proposal. This revision represented an important and rare event, and was an opportunity to assess the legal status and role of Swiss ODL. In this research, we examined the structure and content of this revised Swiss list, by comparing it to other official recommendations and ODLs, including those of the International Labour Organization (ILO) and the European Commission (EC). In addition, we assessed the effectiveness of the Swiss ODL from the occupational and public health perspectives, in considering the process of reporting and recognition of occupational diseases as a measure for protecting the health of workers. Although the Swiss ODL appears to be in accordance with the ILO and EC recommendations, its role as a legal mechanism of workers’ protection is not optimal. Its effectiveness is limited by the conditions for recognising a disease as occupational, which are determined by Swiss federal law and are stricter than in other countries. The overall burden of occupational diseases has a significant economic, social and moral impact on working populations, their families and society as a whole. As such, more transparency with respect to the ODL revision and conditions for recognising occupational disease and to the data on recognised and reported cases, along with continuous education of physicians are required to enhance the effectiveness of the Swiss system of recognition and reporting of occupational diseases and protection of Swiss workers.

Evolution of gynaecologists' practices regarding the implementation of Swiss legislation on maternity protection at work between 2008 and 2017.

BACKGROUND: In accordance with the International Labour Organization’s Maternity Protection Convention (No. 183) and European Union Directive 92/857CEE (1992), Switzerland’s Labour Law and its Maternity Protection Ordinance (OProMa) aim to protect the health of pregnant employees and their future children while enabling them to pursue their working activities. Gynaecologists-obstetricians have a key role in this legislation, particularly through the prescription of preventive leave for patients who would otherwise face dangerous or arduous tasks in the absence of an adequate risk analysis or suitable protective measures. However, international and national literature suggests that gynaecologists-obstetricians may encounter difficulties in fulfilling their role. AIMS: This study aimed to: (1) describe the practices and difficulties encountered by gynaecologists-obstetricians in the practical implementation of the OProMa; and (2) compare the evolution of these practices and difficulties between 2008 and 2017. METHODS: A survey by questionnaire was conducted in 2008 and repeated in 2017. Both surveys focused on gynaecologists-obstetricians working in the French-speaking part of Switzerland (in private practices, hospitals or both). Descriptive and comparative analyses were carried out. RESULTS: 83 gynaecologists-obstetricians responded in 2008 and 93 in 2017: response rates of 47% and 32%, respectively. In 2017, gynaecologists-obstetricians were more likely to ask questions about occupational risks faced by their patients when consulted by working mothers about their pregnancies. The estimated percentage of patients exposed to an occupational risk remained constant (20% in 2008 and 22% in 2017). Communication and collaboration with employers were reported to be difficult in both surveys, even though these are key elements in the implementation of the OProMa. Collaboration with occupational physicians, however, was more frequent in 2017. CONCLUSION: In 2017, gynaecologists-obstetricians showed a greater awareness of occupational risks and collaborated more frequently with occupational health specialists. However, the application of the OProMa remained limited over the studied time period. Improving training of gynaecologists-obstetricians in this field could be a significant factor in encouraging better implementation of the current legislation. Moreover, gynaecologists-obstetricians need to be given the necessary support to enable their clinical practice to evolve towards a more preventive type of medicine. Collaboration with relevant stakeholders, including occupational physicians, midwives and workers, should be encouraged.

Implementation of the Swiss ordinance on maternity protection at work in companies in French-speaking Switzerland.

BACKGROUND: Switzerland's Ordinance on Maternity Protection at Work (OProMa) requires that companies take the necessary measures to ensure that pregnant employees can continue working without danger. OBJECTIVE: To investigate the extent of compliance with OProMa within companies in French-speaking Switzerland as well as factors which facilitate and obstruct the ordinance's implementation. METHODS: A stratified random telephone survey of 202 companies from the healthcare and food industry was conducted. Descriptive and correlational statistics were calculated. Responses to open questions were analysed thematically. RESULTS: Only a minority of companies performed risk analyses or adapted employees' workstations, as per the legislation. OProMa was implemented more effectively in larger companies than smaller ones, in public rather than private ones, in the healthcare sector rather than the food industry, and when the person responsible for the wellbeing of pregnant employees within the company had undergone specific training on the subject. Data extrapolation suggested that only 2% of pregnant employees in French-speaking Switzerland's food industry and 12% in its healthcare sector are properly protected according to OProMa's provisions. CONCLUSIONS: Maternity protection in French-speaking Switzerland's companies urgently requires improvement. In addition to the apparent need for stronger incentives and for monitoring of companies, our findings indicate a need to provide them with resources to meet OProMa's provisions.

Effect of Osteopathic Manipulative Treatment vs Sham Treatment on Activity Limitations in Patients With Nonspecific Subacute and Chronic Low Back Pain: A Randomized Clinical Trial.

Importance: Osteopathic manipulative treatment (OMT) is frequently offered to people with nonspecific low back pain (LBP) but never compared with sham OMT for reducing LBP-specific activity limitations. Objective: To compare the efficacy of standard OMT vs sham OMT for reducing LBP-specific activity limitations at 3 months in persons with nonspecific subacute or chronic LBP. Design, Setting, and Participants: This prospective, parallel-group, single-blind, single-center, sham-controlled randomized clinical trial recruited participants with nonspecific subacute or chronic LBP from a tertiary care center in France starting February 17, 2014, with follow-up completed on October 23, 2017. Participants were randomly allocated to interventions in a 1:1 ratio. Data were analyzed from March 22, 2018, to December 5, 2018. Interventions: Six sessions (1 every 2 weeks) of standard OMT or sham OMT delivered by nonphysician, nonphysiotherapist osteopathic practitioners. Main Outcomes and Measures: The primary end point was mean reduction in LBP-specific activity limitations at 3 months as measured by the self-administered Quebec Back Pain Disability Index (score range, 0-100). Secondary outcomes were mean reduction in LBP-specific activity limitations; mean changes in pain and health-related quality of life; number and duration of sick leaves, as well as number of LBP episodes at 12 months; and consumption of analgesics and nonsteroidal anti-inflammatory drugs at 3 and 12 months. Adverse events were self-reported at 3, 6, and 12 months. Results: Overall, 200 participants were randomly allocated to standard OMT and 200 to sham OMT, with 197 analyzed in each group; the median (range) age at inclusion was 49.8 (40.7-55.8) years, 235 of 394 (59.6%) participants were women, and 359 of 393 (91.3%) were currently working. The mean (SD) duration of the current LBP episode was 7.5 (14.2) months. Overall, 164 (83.2%) patients in the standard OMT group and 159 (80.7%) patients in the sham OMT group had the primary outcome data available at 3 months. The mean (SD) Quebec Back Pain Disability Index scores for the standard OMT group were 31.5 (14.1) at baseline and 25.3 (15.3) at 3 months, and in the sham OMT group were 27.2 (14.8) at baseline and 26.1 (15.1) at 3 months. The mean reduction in LBP-specific activity limitations at 3 months was -4.7 (95% CI, -6.6 to -2.8) and -1.3 (95% CI, -3.3 to 0.6) for the standard OMT and sham OMT groups, respectively (mean difference, -3.4; 95% CI, -6.0 to -0.7; P = .01). At 12 months, the mean difference in mean reduction in LBP-specific activity limitations was -4.3 (95% CI, -7.6 to -1.0; P = .01), and at 3 and 12 months, the mean difference in mean reduction in pain was -1.0 (95% CI, -5.5 to 3.5; P = .66) and -2.0 (95% CI, -7.2 to 3.3; P = .47), respectively. There were no statistically significant differences in other secondary outcomes. Four and 8 serious adverse events were self-reported in the standard OMT and sham OMT groups, respectively, though none was considered related to OMT. Conclusions and Relevance: In this randomized clinical trial of patients with nonspecific subacute or chronic LBP, standard OMT had a small effect on LBP-specific activity limitations vs sham OMT. However, the clinical relevance of this effect is questionable. Trial Registration: ClinicalTrials.gov Identifier: NCT02034864.

[Detection and treatment of burnout by physicians of Unisanté]. / Repérage et prise en charge des patients en burnout par les médecins d'Unisanté.

Lacking diagnostic standards, the prevalence of Occupational Burnout (OB) remains uncertain. Unisanté aimed to evaluate its magnitude in its patients and to evaluate the medical practices related to OB in two of its departments, the Department of the Policlinics (DDP) and the Department of Occupational and Environmental Health (DSTE). An online survey has shown that 43/55 of the physicians participating in the survey have already diagnosed patients with OB in their practice. Two focus groups allowed to evaluate the interest and usefulness of a standardized diagnostic tool for physicians of the DDP and the DSTE. The tool turned out not to be appropriate in its present form, but this work allowed to sensitize physicians to OB and to clarify the recommendations for the screening and treatment of OB patients at Unisanté.

Faute de standard diagnostique, la prévalence de burnout professionnel (BP) reste incertaine. Unisanté a souhaité évaluer son ampleur dans sa patientèle et décrire les pratiques médicales en rapport au BP dans 2 de ses départements, le Département des policliniques (DDP) et le Département santé, travail et environnement (DSTE). Une enquête en ligne a montré que 43/55 médecins participant à l'étude ont déjà diagnostiqué des patients en BP dans leur pratique. Deux focus groups ont permis d'évaluer l'intérêt et l'utilité d'un outil diagnostique standardisé pour les médecins du DDP et du DSTE. L'outil s'est avéré peu adapté sous sa forme actuelle, mais ce travail a permis de sensibiliser les médecins au BP et de clarifier les recommandations de dépistage et de prise en charge des patients en BP à Unisanté.

Implementation of maternity protection legislation: Gynecologists' perceptions and practices in French-speaking Switzerland.

BACKGROUND: In several countries, maternity protection legislations (MPL) confer an essential role to gynecologist-obstetricians (OBGYNs) for the protection of pregnant workers and their future children from occupational exposures. This study explores OBGYNs' practices and difficulties in implementing MPL in the French-speaking part of Switzerland. METHODS: An online survey was sent to 333 OBGYNs. Data analysis included: 1) descriptive and correlational statistics and 2) hierarchical cluster analysis to identify patterns of practices. RESULTS: OBGYNs evoked several problems in MPL implementation: absence of risk analysis in the companies, difficult collaboration with employers, lack of competencies in the field of occupational health. Preventive leave was underused, with sick leave being prescribed instead. Training had a positive effect on OBGYNs' knowledge and implementation of MPL. Hierarchical cluster analysis highlighted three main types of practices: 1) practice in line with legislation; 2) practice on a case-by-case basis; 3) limited practice. OBGYNs with good knowledge of MPL more consistently applied its provisions. CONCLUSION: The implementation of MPL appears challenging for OBGYNs. Collaboration with occupational physicians and training might help OBGYNs to better take on their role in maternity protection. MPL in itself could be improved.

Should systemic sclerosis be recognised as an occupational disease in Switzerland?

Systemic sclerosis is a rare autoimmune disease characterised by a multifactorial aetiology involving a gene–environment interaction. Despite the growing epidemiological arguments for odds ratio (OR) data showing an association with occupational exposure, systemic sclerosis is not currently included in the list of recognised occupational diseases in Switzerland, unlike other northern European countries. Future recognition will be conditional on the demonstration of a strong association between the disease and occupational exposure in the scientific literature. The present article’s main goal is to present five cases of systemic sclerosis investigated for possible occupational aetiologies during occupational pathology consultations at the Institute for Work and Health, in Lausanne. The occupational aetiologies of these cases are discussed against the background of a literature review of publications from the past 20 years in order to determine whether recognition as an occupational disease is possible within Switzerland’s legal framework. Epidemiological studies of systemic sclerosis have identified strong associations with occupational factors such as exposure to silica and solvents, with ORs >2, and weaker associations with epoxy resins and welding fumes. Other occupational exposures are also known to induce systemic sclerosis-like diseases, such as vinyl chloride disease and toxic oil syndrome. All five patients had been exposed to either silica, solvents, or both. Given their exposure and the data in the literature, four patients had their cases declared to their accident insurance companies and two of them were recognised as suffering from an occupational disease by the Swiss National Accident Insurance Fund. Our literature review enabled us to design a short questionnaire to help general practitioners and rheumatologists to identify those patients with systemic sclerosis who are likely to have their illness recognised as an occupational disease.

Implementation, mechanisms and effects of maternity protection legislation: a realist narrative review of the literature.

PURPOSE: Most industrialized countries have introduced maternity protection legislation (MPL) to protect the health of pregnant workers and their unborn children from workplace exposure. This review aimed to assess this legislation's level of implementation, barriers and facilitators to it, and its expected or unexpected effects. METHODS: A realist narrative review was conducted. Keyword searches of the PubMed, CINAHL, PsycINFO, MIDIRS, Sociological abstracts and Google Scholar electronic databases were performed in March 2018. RESULTS: The 42 publications included show that the implementation of MPL is deficient in most countries. Allowing pregnant women to withdraw from work on preventive leave or sick leave is favored over workplace adaptations or worker reassignments. The publications highlight mechanisms which encourage or obstruct the enforcement of legislation at the levels of the individual, the physical and social environment, and the macrosocial context. The delay between the conception and implementation of maternity protection measures appears to be a major barrier to the efficacy of MPL. The literature also suggests that unexpected adverse effects, such as degradation in working relationships or discrimination can obstruct the implementation of protective measures. CONCLUSIONS: This study showed the need for a better implementation of MPL during pregnancy. Further research and recommendations for improvements in MPL should consider the diverse mechanisms and effects of its implementation. Barriers and adverse effects of this implementation do not only ensure a lack of information or awareness about MPL, but are also linked to contradictions between requirements to protect employment and protect pregnancy.

Protection of pregnant women at work in Switzerland: practices, obstacles and resources. A mixed-methods study protocol.

INTRODUCTION: Like most industrialised countries, Switzerland has introduced legislation to protect the health of pregnant workers and their unborn children from workplace exposure. This legislation provides for a risk assessment, adaptations to workplaces and, if the danger is not eliminated, preventive leave (prescribed by a gynaecologist). This study's first objective is to analyse the degree to which companies, gynaecologists and midwives implement the law. Its second objective is to understand the obstacles and resources of this implementation, with a focus on how relevant stakeholders perceive protective measures and their involvement with them. METHODS AND ANALYSIS: Data will be collected using mixed methods: (1) online questionnaires for gynaecologists and midwives; telephone questionnaires with company human resources (HR) managers in the healthcare and food production sectors; (2a) case studies of 6-8 companies in each sector, including interviews with stakeholders such as women workers, HR managers and occupational health physicians; (2b) two focus groups, one involving occupational physicians and hygienists, one involving labour inspectors.Quantitative data will be analysed statistically using STATA software V.15. Qualitative data will be transcribed and thematically analysed using MaxQDA software. ETHICS AND DISSEMINATION: The Human Research Ethics Committee of the Canton Vaud (CER-VD) has certified that this research study protocol falls outside of the field of application of the Swiss Federal Act on Research Involving Humans.The publications and recommendations resulting from this study will form the starting point for future improvements to the protection of pregnant women at work and their unborn children.This study started in February 2017 and will continue until January 2020.

Nasal fibroscopy as a routine screening procedure of sinonasal adenocarcinoma of woodworkers: French longitudinal case study.

BACKGROUND: The purpose of this study was to assess the relevancy of flexible nasoendoscopy as a routine screening procedure of sinonasal adenocarcinoma among people occupationally exposed to wood dust. METHODS: This study included woodworkers, occupationally exposed to wood dust. Evaluations were scheduled at the time of inclusion (T0) and after a 2-year period (T1). A questionnaire was used for standardized data collection. The score was based on anatomic landmarks on each side that are parts of the olfactory clefts: the area of middle turbinate, the anterior part of the olfactory cleft, the top of the choanal arch, the spheno-ethmoidal recess, the posterior part of the olfactory cleft, and the middle part of the olfactory cleft. RESULTS: A total of 965 nasoendoscopies (T0+T1) were performed. Olfactory clefts were visualized in 72% of the cases. Nasoendoscopies revealed pathological findings in 33.6% of cases: polyps, thick nasal secretion aspect, mucous edema, retractile scars and synechia, crusts, mucous erythema, and growth. One case of carcinoma was confirmed. Adverse effects (epistaxis, blood mark on the endo-sheath, sneezing, or rhinorrhea) after the medical procedure occurred in 30% of cases without severe complications. CONCLUSION: Flexible nasoendoscopy offers meaningful efficacy and a promising safety profile, and, therefore, could become the new cornerstone of the routine screening procedure of sinonasal adenocarcinoma among woodworkers.
