- Abstract
Background Occupational diisocyanate-induced extrinsic allergic alveolitis (EAA) is a rare and probably underestimated diagnosis. Two acute occupational EAA cases have been described in this context, but neither of them concerned hexamethylene diisocyanate (HDI) exposure. Aims To investigate the cause of a life-threatening EAA arising at work in a healthy 30-year-old female paint quality controller. Methods Occupational medical assessment, workplace evaluation, airborne and biological monitoring and immunodermatological tests. Results Diagnosis of EAA relied on congruent clinical and radiological information, confirmed occupational HDI exposure and positive IgG antibodies and patch tests. The patient worked in a small laboratory for 7 years, only occasionally using HDI-containing hardeners. While working with HDI for 6 h, she developed breathlessness, rapidly progressing to severe respiratory failure. Workplace HDI airborne exposure values ranged from undetectable levels to 4.25 p.p.b. Biological monitoring of urinary hexamethylene diamine in co-workers ranged from <1.0 to 15.4 μg/g creatinine. Patch tests 8 months later showed delayed skin reaction to HDI at 48 h. Subsequent skin biopsy showed spongiotic dermatitis with infiltration of CD4+ and CD8+ T cells. Conclusions We believe this is the first reported case of acute life-threatening EAA following exposure to HDI. Low concentrations of airborne HDI and relatively high urinary hexamethylene diamine suggest significant skin absorption of HDI could have significantly contributed to the development of this acute occupational EAA

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.

- Abstract
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., Competing Interests: Declaration of Competing Interest None Declared, (Copyright © 2021.

- Abstract
Aims: In Switzerland, certain patients with disabilities and reduced working ability are entitled to a disability pension granted by the Swiss Federal Social Insurance Office (FSIO). The aim was to assess the evolution of disability pension and work capacity after kidney transplantation and thereby pilot the procedures linking FSIO data with Swiss Transplant Cohort Study (STCS) data., Methods: The current study pilot tested the record linkage of FSIO data with data from the STCS in a single-centre, observational setting. Patients were requested to consent to the use of their Swiss social security number (SSSN) for the purpose of record linkage. A privacy preserving trust centre approach was implemented with blinded statistical analysis., Results: Between May 2008 and December 2015, 282 working-age renal transplant recipients of the University Hospital of Basel transplant centre were eligible for inclusion and 136 (48%, median age 48 years) consented to the use of their social security number and record linkage. The FSIO datasets of all patients were successfully retrieved and linked to STCS data in the trust centre and were numerically analysable. Yearly FSIO allowance data were available for the entire study duration. Fifty-five patients (40%) were registered as disability insurance recipients (DIR). In the entire population, the proportion of working patients slightly decreased from 76% to 72% between the pre-transplant and the post-transplant period. This was due to the lower proportion of patients working after transplantation in DIR compared with non-recipients (non-DIR) (DIR: 60% before vs 44% after; non-DIR: 83% before vs 88% after). In the DIR group, the proportion of patients not working increased from 36% to 49%, whereas in non-DIR the proportion changed only marginally (14% to 12%). The average disability insurance allowance was CHF 1172 per month. It changed from CHF 1135 before transplantation to CHF 1209 after transplantation (p = 0.59)., Conclusions: In the Swiss healthcare and social insurance system, record linkage studies combining clinical datasets with data from FSIO are feasible but associated with great efforts and resource needs. The lack of changes in disability allowances after kidney transplantation should be further investigated in the nationwide setting.

- Abstract
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.

- Abstract
The aim of this study was to determine the prevalence of symptoms and respiratory diseases and to assess respiratory function in stones crushers stones in the province of Haut Katanga, Democratic Republic of Congo (DRC). This cross-sectional analytical study included 293 stones crushers and 295 office workers from public administrative services. A standardized respiratory health questionnaire was used, and lung function test performed with the use of peak flow-meters. PM 2.5 and volatile organic compounds (VOC) in different places of work have also been measured. The prevalence of respiratory symptoms was markedly higher in dust-exposed cement carriers than in controls. Air dust measurements showed higher mean PM 2.5 [197.5 μg/m
3 (range: 185-210 μg/m3 ) vs 33.5 μg/m3 (range: 22-45 μg/m3 )] and VOC [1.95 mg/m3 (1.5-2.4 mg/m3 ) vs 0.75 mg/m3 (0.6-0.9 mg/m3 )] levels at stones crushers' worksites as compared with the control sites. On the other hand, peak flow rate (PEFR) was significantly lower in the exposed group as compared with the control group (421.84± 88.18 l/mn vs 450.37 ± 70.90 l/mn; p< 0.05). It is necessary to improve the environment and occupational conditions of stones crushers., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright © 2021 SFMTSI.)- Published

- Abstract
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.

- Abstract
Background and Aim: Environmental and occupational exposure to high dust levels are known to be associated with lung function impairment. We assessed the ambient air quality in the working environment and the respiratory health of female stone quarry workers in Lubumbashi, Democratic Republic of Congo (DRC) in a context of severe economic, security, and health crises., Methods: This was a case-control study conducted in three stone quarry sites. Participants were 256 dust-exposed female stone quarry workers matched to 256 unexposed female office workers and market tax collectors ( N = 512). They each answered a structured respiratory health questionnaire and underwent physical examination and a lung function test with the use of a spirometer and peak flow meter. Quality of ambient air in the working environment was assessed by means of a BRAMC air quality monitor (BR-AIR-329)., Results: Results showed that exposed women did not use any personal protective equipment (PPE); in quarry sites, abnormally high levels of PM
2.5 (205 ± 13.2 μg/m3 vs. 31.3 ± 10.3 μg/m3 in control sites; p < 0.001) and volatile organic compounds (VOC, 2.2 ± 0.2 μg/m3 vs. 0.5 ± 0.3 μg/m3 , respectively; p < 0.01) were found. Furthermore, respiratory complaints were more common among exposed women (32.4% vs. 3.5% in controls; p < 0.01), who had abnormal chest auscultation and reduced lung capacity than controls (mean PEFR: 344.8 ± 2.26 and 405 ± 67.7 L/s, respectively; p < 0.001 Conclusion. Findings from this study show that in the midst of severe crises in the DRC, women stone quarry workers are exposed to abnormally high levels of respiratory hazards, which contribute to impaired lung function. There is a need to regulate quarry work and improve the working conditions in quarry sites in the DRC.- Published

- Abstract
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., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Memory for affective events plays an important role in determining people's behavior and well-being. Its determinants are far from being completely understood. We investigated how recognition memory for affective pictures depends on pictures' motivational significance (valence and arousal), complexity (figure-ground compositions vs. scenes), and social content (pictures with people vs. without people) and on observers' age and gender. Younger, middle-aged, and older adults viewed 84 pictures depicting real-life situations. After a break, the participants viewed 72 pictures, half of which had been viewed previously and half of which were novel, and were asked to endorse whether each picture was novel or had been presented previously. Hits, false alarms, and overall performance (discrimination accuracy) were our dependent variables. The main findings were that, across participants, recognition memory was better for unpleasant than pleasant pictures and for pictures depicting people than pictures without people. Low-arousal pictures were more accurately recognized than high-arousal pictures, and this effect was significantly larger among middle-aged and older adults than younger adults. Recognition memory worsened across adulthood, and this decline was steeper among men than women. Middle-aged and older women outperformed their male counterparts. This study suggests that how well we are able to successfully discriminate previously seen pictorial stimuli from novel stimuli depends on several pictures' properties related to their motivational significance and content, and on observer's age and gender., (© 2019 Scandinavian Psychological Associations and John Wiley & Sons Ltd.)

- Abstract
Shift work is associated with increased risk of chronic diseases due to circadian rhythm disruptions and behavioral changes such as in eating habits. Impact of type of shifts and number of night shifts on energy, nutrient and food intake is as yet unknown. Our goal was to analyze shift workers' dietary intake, eating behavior and eating structure, with respect to frequency of nights worked in a given week and seven schedule types. Eating habits and dietary intakes of 65 male shift workers were analyzed in three steps based on 365 24-h food records: (1) according to the number of nights, (2) in a pooled analysis according to schedule type, and (3) in search of an interaction of the schedule and the timing of intake. Mean nutrient and food group intake during the study period did not depend on the number of nights worked. Amount and distribution of energy intake as well as quality of food, in terms of nutrient and food groups, differed depending on the type of schedule, split night shifts and recovery day (day after night shift) being the most impacted. Shift workers' qualitative and quantitative dietary intakes varied between different schedules, indicating the need for tailored preventive interventions.

- Abstract
Music performance anxiety (MPA) is a major problem for music students. It is largely unknown whether music students who experience high or low anxiety differ in their respiratory responses to performance situations and whether these co-vary with self-reported anxiety, tension, and breathing symptoms. Affective processes influence dynamic respiratory regulation in ways that are reflected in measures of respiratory variability and sighing. This study had two goals. First, we determined how measures of respiratory variability, sighing, self-reported anxiety, tension, and breathing symptoms vary as a function of the performance situation (practice vs. public performance), performance phase (pre-performance vs. post-performance), and the general MPA level of music students. Second, we analyzed to what extent self-reported anxiety, tension, and breathing symptoms co-vary with the respiratory responses. The participants were 65 university music students. We assessed their anxiety, tension, and breathing symptoms with Likert scales and recorded their respiration with the LifeShirt system during a practice performance and a public performance. For the 10-min periods before and after each performance, we computed number of sighs, coefficients of variation (CVs, a measure of total variability), autocorrelations at one breath lag (ARs(1), a measure of non-random variability) and means of minute ventilation (V'
E ), tidal volume (VT ), inspiration time (TI ), and expiration time (TE ). CVs and sighing were greater whereas AR(1) of V'E was lower in the public session than in the practice session. The effect of the performance situation on CVs and sighing was larger for high-MPA than for low-MPA participants. Higher MPA levels were associated with lower CVs. At the within-individual level, anxiety, tension, and breathing symptoms were associated with deeper and slower breathing, greater CVs, lower AR(1) of V'E , and more sighing. We conclude that respiratory variability and sighing are sensitive to the performance situation and to musicians' general MPA level. Moreover, anxiety, tension, breathing symptoms, and respiratory responses co-vary significantly in the context of music performance situations. Respiratory monitoring can add an important dimension to the understanding of music performance situations and MPA and to the diagnostic and intervention outcome assessments of MPA., (Copyright © 2020 Guyon, Cannavò, Studer, Hildebrandt, Danuser, Vlemincx and Gomez.)- Published

- Abstract
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.

- Abstract
Background: Micronuclei (MNs) are extranuclear DNA-containing bodies and determining MN frequencies is a measure of genomic instability. An age-related increase in MN frequencies in lymphocytes has been quantified, but this effect has not yet been measured in nasal and buccal cells., Methods: We determined the effect of age on the MN frequency distributions in buccal and nasal cells among a sample of a general adult population in Switzerland. To maximize the power to detect an effect of age in our population study, we recruited preferentially younger and older working age adults. We harvested buccal and nasal cells from 32 young (19-36 year) and 33 working age (47-71 years) participants. The collected cells were washed, centrifuged, and stained (Feulgen) before microscopic manual counting in 2000 cells. Based on these results, we developed an age-dependent background MN frequency chart to help interpret an individual's MN frequency score as an early signal for the effect of genotoxic exposure., Results: MN frequencies were respectively 0.53‰ and 0.47‰ for buccal and nasal among the younger and 0.87‰ and 1.03‰ in the older working age group. This corresponded to a multiplicative slope of 14% and 20% per 10 years of age for buccal and nasal cells, respectively., Conclusion: Based on our study results, we are able to propose an approach for interpreting an individual's MN screening results., (Copyright © 2019.

- Abstract
How top-down and bottom-up factors combine to determine eye movements during affective picture viewing is far from being completely understood. We investigated how observers' fixation frequency and scanpath length - two indices of information seeking and intake - are related to self-reported valence (pleasantness) and arousal and depend on gender, age, and repeated exposure during affective picture viewing. We tracked the eye movements of 157 younger, middle-aged, and older adults when viewing 14 picture series each consisting of six thematically and affectively similar pictures. Participants' valence and arousal ratings were registered for each series. Fixation frequency and scanpath length increased with self-rated unpleasantness and arousal and decreased across the six pictures within series. This decrease was age- and arousal-dependent. Compared to men, women exhibited a more exploratory scanning behavior. These findings suggest that observers' affective appraisal, gender and age and repeated exposure to affective visual stimuli influence visual information seeking and intake., (Copyright © 2019 Elsevier B.V.

- Abstract
A biomarker-based approach using micronucleus (MN) (extranuclear DNA-containing bodies) frequencies in buccal cells has been proposed to monitor workers exposed to aero-digestive carcinogens for early detection of occupational cancer. To assess this non-invasive MN approach, we sought to understand: (A) What is the extent of MN frequency increase in occupationally exposed over non-exposed populations across studies published in the scientific literature for buccal cells; and (B) Which types of occupational exposures give relevant summary MN ratios across studies published in the scientific literature. A systematic literature review was performed, and the MN frequency ratios for buccal cells were calculated for each occupational study. Meta-analytic techniques were applied using the confidence interval or a standard error on the log-transformed ratio. Exposure categories were developed based on similar occupational exposures or jobs. A summary ratio and proportion of variance explained (the I
2 index) were derived assuming a Gaussian random effect model for each exposure category. The meta-analysis of the published literature (n = 96 studies) showed large random variability between studies within each category (I2 > 90%), except where exposures were to a single carcinogenic substance (e.g. formaldehyde, silica) or similar jobs were performed (e.g. antineoplastic dispensing, gasoline attendants). The greatest summary frequency ratios were for silica (FR 9.02 95%CI 6.83-11.93), formaldehyde (FR 4.81 95%CI 2.19-10.60), and for hairdressers as an exposure category (FR 7.06 95%CI 3.96-12.57). The unexplained between-study variability can be related to exposures to mixtures of carcinogens with unknown mechanisms. If the latter had been measured, the between-study variability may have been explained. We conclude that better exposure assessments are needed to understand the relationship between occupational exposures and MN frequency responses in buccal cells. Nevertheless, our analysis indicates that the buccal cell MN assay is a promising tool for surveying workers exposed to genotoxic agents., (Copyright © 2019 Elsevier B.V.

- Abstract
Background Return to work with or after a chronic disease is not a very well understood process, influenced by a variety of personal, professional, societal and medical factors. The aim of this study is to identify predictors for return to work 12 months after a solid organ transplant applying a bio-psycho-social model. Methods This study is based on patients included in the Swiss Transplant Cohort Study, a national prospective multicentre cohort, who underwent a first solid organ transplant (kidney, liver, heart, lung). Bio-psycho-social factors were tested and predictors of return to work identified using logistic regression models. Results Among the 636 patients included in the study, 49.8% (317) were employed 12 months post-transplant. The major predictor for returning to work 12 months posttransplant was pre-transplant employment status (OR 10.8). Accordingly, the population was stratified in employed and not employed pre-transplant groups. Age, self-perceived health (6 months post-transplant) and the transplanted organ were significantly associated with post-transplant employment status in both groups. Return to work was influenced by education, depression (6 month post-transplant) and waiting time in the employed pre-transplant group and by invalidity pension in the not employed pre-transplant group. Conclusion Employment status pre-transplant being highly associated with employment status post-transplant, the process promoting return to work should be started well before surgery. Biomedical, psychological and social factors must be taken into account to promote return to work in transplanted patients.

- Abstract
Objective: Subjective health complaints (SHC) are frequent in musicians. These complaints may be particularly distressing in this population because they are performance relevant. This paper aims at testing a model positing that (a) perseverative cognition (PC) predicts sleep duration/quality, (b) sleep duration/quality predicts SHC and (c) mood is a mediator of these associations., Design: Participants were 72 music students (mean age (SD): 22.7 (3.0) years), and the assessment period consisted of seven consecutive days, with a solo performance on the fifth day., Main Outcome Measures: Self-reported total sleep time (TST) and sleep quality were assessed 30 min after wake-up, and objective TST/sleep quality were assessed with an actigraphy watch. PC and mood were measured five times a day. Daily SHC were assessed at 9 p.m., Results: PC did not significantly predict sleep duration/quality. Self-reported and objective TST and sleep quality were all significantly associated with SHC. Mood played a mediating role in each of these relationships with the exception of objective sleep quality., Conclusion: The tested model on the association among PC, sleep and SHC and the mediating role of mood received partial support, highlighting the importance of sleep and mood in the emergence of SHC among university music students.

- Abstract
Objective: Firefighters' eating habits may be an additional risk factor for metabolic diseases. We assessed eating habits of firefighters, compared them with national guidelines, and evaluated the impact of a prevention program., Methods: Twenty-eight professional firefighters from a Swiss airport benefited from a healthy-eating program. Food intake, eating behavior, and anthropometric data were collected at baseline and 1-year follow-up using an electronic food record, questionnaires, and bio-impedance., Results: Participants had unbalanced diets with low-quality food choices associated with low intakes of fibers and micronutrients compared with national guidelines. Intervention did not impact eating habits or anthropometrics data at the group level, but changes were measured in sub-groups. Main reported barriers for healthy eating were lack of motivation, prioritization, or time., Conclusions: Intensive and culturally tailored prevention interventions targeting nutritional behaviors are needed at the individual, group, and organizational levels.

- Abstract
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.

- Abstract
Purpose: In Democratic Republic of the Congo (DRC), informal coltan mining has been expanding amidst increased insecurity due to armed conflicts. We investigated the impact of occupational dust-exposure on the respiratory health of Congolese coltan miners., Methods: In total, 441 Congolese workers participated in this study, including 199 informal coltan miners and 242 office workers (controls). Information on respiratory complaints was collected using two standardized questionnaires. Physical examination (vital signs, auscultation) and lung function test (Peak Flow meter) were performed. In addition, workplace airborne PM2.5 and volatile organic compounds (VOC) concentrations were measured., Results: Higher airborne PM2.5 (range 180-210 µg/m
3 ) and VOC (range 1.4-2.3 µg/m3 ) levels were detected at coltan mining work stations as compared with control sites (19-44 and 0.5-0.8 µg/m3 , respectively). All respiratory complaints and disorders were more prevalent in informal coltan miners than in controls. Additionally, a markedly lower mean PEFR was observed in coltan miners than in controls (347.93 ± 6.88 vs. 493.23 ± 67.38 L/min, respectively). Moreover, positive associations between informal coltan mining and almost all respiratory complaints were observed, except wheezing at effort and night cough. On the other hand, an inverse association was observed between lung function (PEFR) and PM2.5 exposure, between PEFR and VOC exposure, and also between PEFR and current smoking., Conclusions: This study showed high prevalence of respiratory complaints in Congolese informal coltan miners, suggesting the necessity to implement efficient occupational safety measures and regulate this informal mining business.- Published

- Abstract
Music performances are social-evaluative situations that can elicit marked short-term neuroendocrine activation and anxious thoughts especially in musicians suffering from music performance anxiety (MPA). The temporal patterns of neuroendocrine activity and concert-related worry and rumination (perseverative cognition, PC) days before and after a concert in low- and high-anxious musicians are unknown. The first goal of the present study was to investigate the prolonged effects of a solo music performance and the effects of trait MPA on salivary cortisol (sC), alpha-amylase (sAA), and concert-related PC. The second goal was to investigate whether concert-related PC is associated with neuroendocrine activity and mediates the effects of measurement day and trait MPA on neuroendocrine responses. Seventy-two university music students collected saliva samples and reported their PC for seven consecutive days. On the fifth day, they performed solo. Measurement day and trait MPA were tested as main predictors of the diurnal area under the curve with respect to ground (sC AUCg, sAA AUCg), awakening responses, and PC. SC AUCg, sAA AUCg, and concert-related PC were highest on concert day. SC AUCg decreased only partially on post-concert days. SAA AUCg remained elevated on the first post-concert day among students with moderate to very high trait MPA. Throughout the assessment period, trait MPA was associated with smaller sC AUCg and higher concert-related PC. Concert-related PC showed significant positive associations with sC AUCg and sAA AUCg but did not mediate the effects of measurement day and trait MPA on these measures. These findings suggest that solo music performances have prolonged neuroendocrine effects and that trait MPA is an important factor having specific effects on university music students' hypothalamic-pituitary-adrenal axis, autonomic nervous system, and cognitive activity., (Copyright © 2018 Elsevier Ltd.

- Abstract
Purpose: The aim of this study was to understand the differential acute effects of two distinct wheat-related dusts, such as field or stored wheat dust handling, on workers' health and how those effects evolved at 6 month intervals., Methods: Exposure, work-related symptoms, changes in lung function, and blood samples of 81 workers handling wheat and 61 controls were collected during the high exposure season and 6 months after. Specific IgG, IgE, and precipitins against 12 fungi isolated from wheat dust were titrated by enzyme-linked immunosorbent assay, dissociation-enhanced lanthanide fluorescence immunoassay, and electrosyneresis. The level of fungi was determined in the workers' environment. Levels of exhaled fraction of nitrogen monoxide (F
E NO) and total IgE were obtained. Exposure response associations were investigated by mixed logistic and linear regression models., Results: The recent exposure to field wheat dust was associated with a higher prevalence for five of six self-reported airway symptoms and with a lower FE NO than those in the control population. Exposure to stored wheat dust was only associated with cough. No acute impact of exposure on respiratory function was observed. Exposure to field wheat dust led to workers' sensitization against the three field fungi Aureobasidum, Cryptococcus, and Phoma, although exposure to storage wheat dust was associated with tolerance. The level of Ig remained stable 6 months after exposure., Conclusion: The clinical picture of workers exposed to field or storage wheat dust differed. The systematic characterization of the aerosol microbial profile may help to understand the reasons for those differences.- Published

- Abstract
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., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

- Abstract
Introduction: Psychosocial suffering entails human, social and economic costs. In Switzerland, 34.4% of workers report chronic work-related stress. Our medical Consultation for Suffering at Work aims to preserve-or restore-the patient's capacity to act and make decisions after a diagnosis of work-related psychological suffering; it also aims to help employees get back to or remain at work. Our hypothesis is that the dynamic of the consultation itself and adherence to its medical advice are active factors of these results., Objectives: Understand changes in patients' work and health status 12 months after a Consultation for Suffering at Work. Determine the effects of the consultation on health and working status via identified active factors: the consultation dynamic and the ability to adhere to the consultation's advice. Evaluate the consultation's effects qualitatively., Materials and Methods: This longitudinal, monocentric study with a quasi-experimental design will include patients consulting between 1 January and 31 December 2018. Changes in patients' work and health status will be analysed using data collected via questionnaires at 0, 3 and 12 months. Qualitative data will be collected via a semi-structured telephone interview 3 months after the consultation. The quantitative part will include 150-170 patients; the qualitative part will include 30., Conclusion: This exploratory research project will provide a better understanding of issues of work-related psychological suffering and effective strategies to support patients. The absence of a control group and the impossibility of applying a randomised controlled design are constraints on this study.

- Abstract
Introduction: Stress is a common phenomenon in medical professions. Breaking bad news (BBN) is reported to be a particularly distressing activity for physicians. Traditionally, the stress experienced by physicians when BBN was assessed exclusively using self-reporting. Only recently, the field of difficult physician-patient communication has used physiological assessments to better understand physicians' stress reactions., Method: This paper's goals are to (a) review current knowledge about the physicians' psychophysiological stress reactions in BBN situations, (b) discuss methodological aspects of these studies and (c) suggest directions for future research., Results: The seven studies identified all used scenarios with simulated patients but were heterogeneous with regard to other methodological aspects, such as the psychophysiological parameters, time points and durations assessed, comparative settings, and operationalisation of the communication scenarios. Despite this heterogeneity, all the papers reported increases in psychological and/or physiological activation when breaking bad news in comparison to control conditions, such as history taking or breaking good news., Conclusion: Taken together, the studies reviewed support the hypothesis that BBN is a psychophysiologically arousing and stressful task for medical professionals. However, much remains to be done. We suggest several future directions to advance the field. These include (a) expanding and refining the conceptual framework, (b) extending assessments to include more diverse physiological parameters, (c) exploring the modulatory effects of physicians' personal characteristics (e.g. level of experience), (d) comparing simulated and real-life physician-patient encounters and (e) combining physiological assessment with a discourse analysis of physician-patient communication., (Copyright © 2017 Elsevier B.V.

- Abstract
Background: Return to work with or after a chronic disease is a dynamic process influenced by a variety of interactions between personal, work, societal and medical resources or constraints. The aim of this study was to identify predictors for employment 12 months after transplantation in kidney patients, applying a bio-psycho-social model., Methods: All kidney patients followed in the Swiss Transplant Cohort between May 2008 and December 2012, aged 18 to 65 were assessed before, 6 and 12 months after transplantation., Results: Of the 689 included patients, 56.2% worked 12 months post- transplantation compared to 58.9% pre-transplantation. Age, education, self-perceived health (6 months post- transplantation), pre- transplantation employment and receiving an organ from a living donor are significant predictors of employment post- transplantation. Moreover, while self-perceived health increased post- transplantation, depression score decreased only among those employed 12 months post- transplantation. Pre- transplantation employment status was the main predictor for post- transplantation employment (OR = 18.6) and was associated with sex, age, education, depression and duration of dialysis. An organ from a living donor (42.1%) was more frequent in younger patients, with higher education, no diabetes and shorter waiting time to surgery., Conclusion: Transplantation did not increase employment in end-stage kidney disease patients but helped maintaining employment. Pre-transplantation employment has been confirmed to be the most important predictor of post-transplantation employment. Furthermore, socio-demographic and individual factors predicted directly and indirectly the post-transplantation employment status. With living donor, an additional predictor linked to social factors and the medical procedure has been identified.

- Abstract
Measures that capture diet as validly and reliably as possible are cornerstones of nutritional research, and mobile-based devices offer new opportunities to improve and simplify data collection. The balance between precision and acceptability of these data collection tools remains debated, and rigorous validations are warranted. Our objective was to develop and evaluate an electronic mobile-based food record for a research setting. We developed e-CA, which includes almost 900 foods and beverages classified in 14 categories and 60 subcategories. e-CA was evaluated using three different methods: (1) usability and acceptability through a logbook and qualitative interviews; (2) dietary intake accuracy through comparison with 2 unannounced 24-h phone recalls on overlapping days; and (3) reliability and process comparison with a paper-based food record in a laboratory setting with a randomized design. e-CA proved to be intuitive and practical and was perceived as modern, trendy, and fun. Comparisons of e-CA with 24-h telephone recalls or paper-based food records in a laboratory setting with two small convenient samples showed good agreement but highlighted the well-known difficulty of estimating portion sizes and a necessary learning time to use the app. e-CA is a functional tool that has the potential to facilitate food intake measurement for research by increasing the pleasure of using the food record tool and reducing the perceived burden for the participants. It also decreases the workload, costs and the risk of transcription errors for researchers., Competing Interests: The authors declare no conflict of interest. The founding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results.

- Abstract
In the present study, we examined how sex and age shape cardiovascular, electrodermal, and pupillary reactivity to picture series within the valence-arousal affective space in a sample of 176 healthy younger, middle-aged, and older men and women. Across participants, heart rate (HR) decelerated with increasing self-reported unpleasantness, whereas skin conductance level (SCL) and pupil size (PS) increased with increasing self-rated arousal. Systolic (SBP) and diastolic (DBP) blood pressure increased with increasing self-rated arousal when valence was pleasant but much less when valence was unpleasant. Compared to women, men exhibited a stronger correlation between valence and HR and an SBP response characterized by larger increases for pleasant high-arousal states and lower change scores for unpleasant low- and high-arousal and pleasant low-arousal states. Men's largest SCL change scores were for pleasant high-arousal states, whereas women's largest SCL change scores were for unpleasant high-arousal states. The arousal-PS relationship was stronger among women, in particular for unpleasant series. From younger to older age, there were decreases in the strength of the valence-HR, arousal-SCL, and arousal-PS relationships. Older adults had larger overall increases in SBP and DBP than younger adults, but the relationships with self-reported valence and arousal were not age dependent. We discuss how the observed sex and age effects may reflect sex and age differences in emotional processing and in basic autonomic nervous system functioning., (Copyright © 2016 Elsevier B.V.

- Abstract
The present study investigated differences between healthy younger, middle-aged, and older adults in their respiratory responses to pictures of different valence and arousal. Expiratory time shortened and end-tidal PCO2 decreased with increasing arousal in all age groups; yet, compared to younger adults, older adults' overall change from baseline was smaller for expiratory time and larger for end-tidal PCO2. Contrary to their younger counterparts, older adults' inspiratory time did not shorten with increasing arousal. Inspiratory duty cycle did not covary with affective ratings for younger adults, increased with unpleasantness for middle-aged adults, and increased with arousal for older adults. Thoracic breathing increased with increasing unpleasantness only among older adults. Age had no effects on mean inspiratory flow and minute ventilation, which both augmented as arousal increased. We discuss how age effects on respiratory response magnitude and pattern may depend on age-associated biological changes or reflect age-related differences in emotional processing., (Copyright © 2016 Elsevier B.V.

- Abstract
Exposure to wood dust, a human carcinogen, is common in wood-related industries, and millions of workers are occupationally exposed to wood dust worldwide. The comet assay is a rapid, simple, and sensitive method for determining DNA damage. The objective of this study was to investigate the DNA damage associated with occupational exposure to wood dust using the comet assay (peripheral blood samples) among nonsmoking wood workers (n = 31, furniture and construction workers) and controls (n = 19). DNA damage was greater in the group exposed to composite wood products compared to the group exposed to natural woods and controls (P < 0.001). No difference in DNA damage was observed between workers exposed to natural woods and controls (P = 0.13). Duration of exposure and current dust concentrations had no effect on DNA damage. In future studies, workers' exposures should include cumulative dust concentrations and exposures originating from the binders used in composite wood products.

- Abstract
Background: Tungsten inert gas (TIG) welding represents one of the most widely used metal joining processes in industry. It has been shown to generate a large majority of particles at the nanoscale and to have low mass emission rates when compared to other types of welding. Despite evidence that TIG fume particles may produce reactive oxygen species (ROS), limited data is available for the time course changes of particle-associated oxidative stress in exposed TIG welders., Methods: Twenty non-smoking male welding apprentices were exposed to TIG welding fumes for 60 min under controlled, well-ventilated settings. Exhaled breathe condensate (EBC), blood and urine were collected before exposure, immediately after exposure, 1 h and 3 h post exposure. Volunteers participated in a control day to account for oxidative stress fluctuations due to circadian rhythm. Biological liquids were assessed for total reducing capacity, hydrogen peroxide (H2O2), malondialdehyde (MDA), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) concentrations at each time point. A linear mixed model was used to assess within day and between day differences., Results: Significant increases in the measured biomarkers were found at 3 h post exposure. At 3 h post exposure, we found a 24 % increase in plasma-H2O2 concentrations ([95%CI: 4 % to 46 %], p = 0.01); a 91 % increase in urinary-H2O2 ([2 % to 258 %], p = 0.04); a 14 % increase in plasma-8-OHdG ([0 % to 31 %], p = 0.049); and a 45 % increase in urinary-8-OHdG ([3 % to 105 %], p = 0.03). Doubling particle number concentration (PNC) exposure was associated with a 22 % increase of plasma-8-OHdG at 3 h post exposure (p = 0.01)., Conclusion: A 60-min exposure to TIG welding fume in a controlled, well-ventilated setting induced acute oxidative stress at 3 h post exposure in healthy, non-smoking apprentice welders not chronically exposed to welding fumes. As mass concentration of TIG welding fume particles is very low when compared to other types of welding, it is recommended that additional exposure metrics such as PNC are considered for occupational risk assessments. Our findings highlight the importance of increasing awareness of TIG welding fume toxicity, especially given the realities of welding workplaces that may lack ventilation; and beliefs among interviewed welders that TIG represents a cleaner and safer welding process.

- Abstract
Mental health problems at work constitute a challenge in the clinical feld, as well in the professional, the economic and the public health perspective. The total costs they generate in Switzerland are equivalent to 3.2% of the Swiss gross domestic product and they very often lead to dismissal. The vast majority of people are treated by their primary care physician. The Institute for Work and Health features a specialized consultation on the topic of suffering at work, offering the primary care physicians a pluridisciplinary advice or support, in a collaborative care prospect. Its action, adapted to each situation's needs, goes from an advice to a referral to specialists that can strengthen the network on a long-term basis (mental health follow-up, supported employment program, legal or social advice).

- Abstract
Coexisting workloads from professional, household and family, and caregiving activities for frail parents expose middle-aged individuals, the so-called "Sandwich Generation", to potential health risks. Current trends suggest that this situation will continue or increase. Thus SG health promotion has become a nursing concern. Most existing research considers coexisting workloads a priori pathogenic. Most studies have examined the association of one, versus two, of these three activities with health. Few studies have used a nursing perspective. This article presents the development of a framework based on a nursing model. We integrated Siegrist's Effort-Reward Imbalance middle-range theory into "Neuman Systems Model". The latter was chosen for its salutogenic orientation, its attention to preventive nursing interventions and the opportunity it provides to simultaneously consider positive and negative perceptions of SG health and SG coexisting workloads. Finally, it facilitated a theoretical identification of health protective factors., (© The Author(s) 2015.)

- Abstract
Emotion regulation plays a key role in mental health and psychopathology. Therefore, it seems important to develop effective forms of emotion regulation. Implementation intentions are if-then plans that help people attain their self-regulatory goals. Perspective-taking and response-focused implementation intentions have been shown to reduce feelings of unpleasantness and arousal, respectively, in response to briefly presented disgusting pictures. The present study addressed the open research questions whether forming these types of implementation intentions is effective in regulating affect during prolonged presentation of disgusting pictures, and whether it is associated with changes in physiological arousal. Eighty-one participants viewed disgusting, neutral, and pleasant pictures of 6 s duration under four instructions: the goal intention to not get disgusted, this goal intention furnished with a perspective-taking or a response-focused implementation intention, and no emotion regulation instructions. The dependent variables were ratings of disgust, valence, arousal, and electrodermal activity. Only perspective-taking implementation intention participants significantly reduced their disgust and unpleasantness as compared to goal-intention and control participants. Arousal and skin conductance did not significantly differ between conditions. The effectiveness of response-focused but not perspective-taking implementation intentions seems to be substantially reduced during sustained exposure duration.

- Abstract
Objectives: To assess consequences of physical violence at work and identify their predictors., Methods: Among the patients in a medicolegal consultation from 2007 to 2010, the subsample of workplace violence victims (n = 185) was identified and contacted again in average 30 months after the assault. Eighty-six victims (47 %) participated. Ordinal logistic regression analyses assessed the effect of 9 potential risk factors on physical, psychological and work consequences summarized in a severity score (0-9)., Results: Severity score distribution was as follows: 4+: 14 %; 1-3: 42 %; and 0: 44 %. Initial psychological distress resulting from the violence was a strong predictor (p < 0.001) of the severity score both on work and long-term psychological consequences. Gender and age did not reach significant levels in multivariable analyses even though female victims had overall more severe consequences. Unexpectedly, only among workers whose jobs implied high awareness of the risk of violence, first-time violence was associated with long-term psychological and physical consequences (p = 0.004). Among the factors assessed at follow-up, perceived lack of employers' support or absence of employer was associated with higher values on the severity score. The seven other assessed factors (initial physical injuries; previous experience of violence; preexisting health problems; working alone; internal violence; lack of support from colleagues; and lack of support from family or friends) were not significantly associated with the severity score., Conclusions: Being a victim of workplace violence can result in long-term consequences on health and employment, their severity increases with the seriousness of initial psychological distress. Support from the employer can help prevent negative outcomes.

- Abstract
Introduction: Occupational exposure to grain dust causes respiratory symptoms and pathologies. To decrease these effects, major changes have occurred in the grain processing industry in the last twenty years. However, there are no data on the effects of these changes on workers' respiratory health., Objectives: The aim of this study was to evaluate the respiratory health of grain workers and farmers involved in different steps of the processing industry of wheat, the most frequently used cereal in Europe, fifteen years after major improvements in collective protective equipment due to mechanisation., Materials and Method: Information on estimated personal exposure to wheat dust was collected from 87 workers exposed to wheat dust and from 62 controls. Lung function (FEV1, FVC, and PEF), exhaled nitrogen monoxide (FENO) and respiratory symptoms were assessed after the period of highest exposure to wheat during the year. Linear regression models were used to explore the associations between exposure indices and respiratory effects., Results: Acute symptoms - cough, sneezing, runny nose, scratchy throat - were significantly more frequent in exposed workers than in controls. Increased mean exposure level, increased cumulative exposure and chronic exposure to more than 6 mg.m (-3) of inhaled wheat dust were significantly associated with decreased spirometric parameters, including FEV1 and PEF (40 ml and 123 ml.s (-1) ), FEV1 and FVC (0.4 ml and 0.5 ml per 100 h.mg.m (-3) ), FEV1 and FVC (20 ml and 20 ml per 100 h at >6 mg.m (-3) ). However, no increase in FENO was associated with increased exposure indices., Conclusions: The lung functions of wheat-related workers are still affected by their cumulative exposure to wheat dust, despite improvements in the use of collective protective equipment.

- Abstract
Background: Highway maintenance workers are constantly and simultaneously exposed to traffic-related particle and noise emissions, both of which have been linked to increased cardiovascular morbidity and mortality in population-based epidemiology studies., Objectives: We aimed to investigate short-term health effects related to particle and noise exposure., Methods: We monitored 18 maintenance workers, during as many as five 24-hr periods from a total of 50 observation days. We measured their exposure to fine particulate matter (diameter ≤ 2.5 μm; PM2.5), ultrafine particles, and noise, and the cardiopulmonary health end points: blood pressure, proinflammatory and prothrombotic markers in the blood, lung function, and fractional exhaled nitric oxide (FeNO) measured approximately 15 hr after work. Heart rate variability was assessed during a sleep period approximately 10 hr after work., Results: PM2.5 exposure was significantly associated with C-reactive protein and serum amyloid A, and was negatively associated with tumor necrosis factor α. None of the particle metrics were significantly associated with von Willebrand factor or tissue factor expression. PM2.5 and work noise were associated with markers of increased heart rate variability, and with increased high-frequency and low-frequency power. Systolic and diastolic blood pressure on the following morning were significantly associated with noise exposure after work, and nonsignificantly associated with PM2.5. We observed no significant associations between any of the exposures and lung function or FeNO., Conclusions: Our findings suggest that exposure to particles and noise during highway maintenance work might pose a cardiovascular health risk. Actions to reduce these exposures could lead to better health for this population of workers.

- Abstract
Wood dust is recognised as a human carcinogen, based on the strong association of wood dust exposure and the elevated risk of malignant tumours of the nasal cavity and paranasal sinuses [sino-nasal cancer (SNC)]. The study aimed to assess genetic damage in workers exposed to wood dust using biomarkers in both buccal and nasal cells that reflect genome instability events, cellular proliferation and cell death frequencies. Nasal and buccal epithelial cells were collected from 31 parquet layers, installers, carpenters and furniture workers (exposed group) and 19 non-exposed workers located in Switzerland. Micronucleus (MN) frequencies were scored in nasal and buccal cells collected among woodworkers. Other nuclear anomalies in buccal cells were measured through the use of the buccal micronucleus cytome assay. MN frequencies in nasal and buccal cells were significantly higher in the exposed group compared to the non-exposed group; odds ratio for nasal cells 3.1 [95% confidence interval (CI) 1.8-5.1] and buccal cells 1.8 (95% CI 1.3-2.4). The exposed group had higher frequencies of cells with nuclear buds, karyorrhectic, pyknotic, karyolytic cells and a decrease in the frequency of basal, binucleated and condensed cells compared to the non-exposed group. Our study confirms that woodworkers have an elevated risk for chromosomal instability in cells of the aerodigestive tract. The MN assay in nasal cells may become a relevant biomonitoring tool in the future for early detection of SNC risk. Future studies should seek to standardise the protocol for MN frequency in nasal cells similar to that for MN in buccal cells.

- Abstract
The present study provides a comprehensive view of (a) the time dynamics of the psychophysiological responding in performing music students (n = 66) before, during, and after a private and a public performance and (b) the moderating effect of music performance anxiety (MPA). Heart rate (HR), minute ventilation (VE), and all affective and somatic self-report variables increased in the public session compared to the private session. Furthermore, the activation of all variables was stronger during the performances than before or after. Differences between phases were larger in the public than in the private session for HR, VE, total breath duration, anxiety, and trembling. Furthermore, while higher MPA scores were associated with higher scores and with larger changes between sessions and phases for self-reports, this association was less coherent for physiological variables. Finally, self-reported intra-individual performance improvements or deteriorations were not associated with MPA. This study makes a novel contribution by showing how the presence of an audience influences low- and high-anxious musicians' psychophysiological responding before, during and after performing. Overall, the findings are more consistent with models of anxiety that emphasize the importance of cognitive rather than physiological factors in MPA.

- Abstract
The so-called < Sandwich Generation > (SG) is characterized by concurrent and competing professional, familial, and informal caregiving workloads. These stressors pose potential health risks. However, the current knowledge about SG characteristics and perceived state of health are insufficient to allow occupational health nurses to develop evidence-based interventions designed for health promotion. We aimed to describe this population and examine the relationships between these coexisting workloads and their perceived health. This study is based on a descriptive, correlational design. Employees of a Swiss public administration completed an electronic questionnaire. Of 844 respondents, 23 % are SG members. Ages of frailed parents or parents-in-law, co-residence with the latters, children still living at home predict that employees could be members of the SG. Perceived physical health status of SG members is rated better than mental health status. The heterogeneity of SG is reflected in three clusters. Finally, physical health score is the only that differs from the other health scores adjusting for clusters and sex. This study provides a foundation for developing preventive interventions targeting the SG.

- Abstract
The investigation of gender differences in emotion has attracted much attention given the potential ramifications on our understanding of sexual differences in disorders involving emotion dysregulation. Yet, research on content-specific gender differences across adulthood in emotional responding is lacking. The aims of the present study were twofold. First, we sought to investigate to what extent gender differences in the self-reported emotional experience are content specific. Second, we sought to determine whether gender differences are stable across the adult lifespan. We assessed valence and arousal ratings of 14 picture series, each of a different content, in 94 men and 118 women aged 20 to 81. Compared to women, men reacted more positively to erotic images, whereas women rated low-arousing pleasant family scenes and landscapes as particularly positive. Women displayed a disposition to respond with greater defensive activation (i.e., more negative valence and higher arousal), in particular to the most arousing unpleasant contents. Importantly, significant interactions between gender and age were not found for any single content. This study makes a novel contribution by showing that gender differences in the affective experiences in response to different contents persist across the adult lifespan. These findings support the "stability hypothesis" of gender differences across age., (© 2013 The Scandinavian Psychological Associations.)

- Abstract
Primary care physicians are among the specialists who most often have to deal with work-related health problems. Musculoskeletal (including the spine and limbs) and psychological problems are the most frequently encountered work-related diseases. In that context, it is essential for the primary care physician to identify the link between a disease and the occupational environment of the patient, in order to deliver appropriate care. This article deals with two clinical cases to illustrate the semiology and therapeutic aspects of burnout, and musculoskeletal disorders of the upper limb, respectively. It gives some clues to the primary care physician, about how to guide his practice in a multimodal way, oriented toward the patient himself, but also toward his occupational environment.

- Abstract
In this study, we assessed the mixed exposure of highway maintenance workers to airborne particles, noise, and gaseous co-pollutants. The aim was to provide a better understanding of the workers' exposure to facilitate the evaluation of short-term effects on cardiovascular health endpoints. To quantify the workers' exposure, we monitored 18 subjects during 50 non-consecutive work shifts. Exposure assessment was based on personal and work site measurements and included fine particulate matter (PM2.5), particle number concentration (PNC), noise (Leq), and the gaseous co-pollutants: carbon monoxide, nitrogen dioxide, and ozone. Mean work shift PM2.5 concentrations (gravimetric measurements) ranged from 20.3 to 321 μg m(-3) (mean 62 μg m(-3)) and PNC were between 1.6×10(4) and 4.1×10(5) particles cm(-3) (8.9×10(4) particles cm(-3)). Noise levels were generally high with Leq over work shifts from 73.3 to 96.0 dB(A); the averaged Leq over all work shifts was 87.2 dB(A). The highest exposure to fine and ultrafine particles was measured during grass mowing and lumbering when motorized brush cutters and chain saws were used. Highest noise levels, caused by pneumatic hammers, were measured during paving and guardrail repair. We found moderate Spearman correlations between PNC and PM2.5 (r = 0.56); PNC, PM2.5, and CO (r = 0.60 and r = 0.50) as well as PNC and noise (r = 0.50). Variability and correlation of parameters were influenced by work activities that included equipment causing combined air pollutant and noise emissions (e.g. brush cutters and chain saws). We conclude that highway maintenance workers are frequently exposed to elevated airborne particle and noise levels compared with the average population. This elevated exposure is a consequence of the permanent proximity to highway traffic with additional peak exposures caused by emissions of the work-related equipment.

- Abstract
Occupational exposures to wood dust have been associated with an elevated risk of sinonasal cancer (SNC). Wood dust is recognized as a human carcinogen but the specific cancer causative agent remains unknown. One possible explanation is a co-exposure to; wood dust and polycyclic aromatic hydrocarbons (PAHs). PAHs could be generated during incomplete combustion of wood due to heat created by use of power tools. To determine if PAHs are generated from wood during common wood working operations, PAH concentrations in wood dust samples collected in an experimental chamber operated under controlled conditions were analyzed. In addition, personal air samples from workers exposed to wood dust (n = 30) were collected. Wood dust was generated using three different power tools: vibrating sander, belt sander, and saw; and six wood materials: fir, Medium Density Fiberboard (MDF), beech, mahogany, oak and wood melamine. Monitoring of wood workers was carried out by means of personal sampler device during wood working operations. We measured 21 PAH concentrations in wood dust samples by capillary gas chromatography-ion trap mass spectrometry (GC-MS). Total PAH concentrations in wood dust varied greatly (0.24-7.95 ppm) with the lowest being in MDF dust and the highest in wood melamine dust. Personal PAH exposures were between 37.5-119.8 ng m(-3) during wood working operations. Our results suggest that PAH exposures are present during woodworking operations and hence could play a role in the mechanism of cancer induction related to wood dust exposure.

- Abstract
The time courses of key biomarkers of exposure to captan and folpet was assessed in accessible biological matrices of orally exposed volunteers. Ten volunteers ingested 1 mg kg(-1) body weight of captan or folpet. Blood samples were withdrawn at fixed time periods over the 72 h following ingestion and complete urine voids were collected over 96 h post-dosing. The tetrahydrophthalimide (THPI) metabolite of captan along with the phthalimide (PI) and phthalic acid metabolites of folpet were then quantified in these samples. Plasma levels of THPI and PI increased progressively after ingestion, reaching peak values ~10 and 6 h post-dosing, respectively; subsequent elimination phase appeared monophasic with a mean elimination half-life (t(½) ) of 15.7 and 31.5 h, respectively. In urine, elimination rate time courses of PI and phthalic acid evolved in parallel, with respective t(½) of 27.3 and 27.6 h; relatively faster elimination was found for THPI, with mean t(½) of 11.7 h. However, phthalic acid was present in urine in 1000-fold higher amounts than PI. In the 96 h period post-treatment, on average 25% of folpet dose was excreted in urine as phthalic acid as compared with only 0.02% as PI. The corresponding value for THPI was 3.5%. Overall, THPI and PI appear as interesting biomarkers of recent exposure, with relatively short half-lives; their sensitivity to assess exposure in field studies should be further verified. Although not a metabolite specific to folpet, the concomitant use of phthalic acid as a major biomarker of exposure to folpet should also be considered., (Copyright © 2011 John Wiley & Sons, Ltd.)
