Authors: Esser Stefan , Heinrich-Heine Sylvester Siegmann
Published: July 2024

Introduction

Mental Health Risk Assessment for Companies with an International Work Force and International Operations

Methods

The International SOS Foundation, together with several academic and occupational health partners and other experts on international work have published a white paper about the methodology and implementation of a mental health risk assessment for companies in Austria, Germany and Switzerland.

Results

While the legal aspects refer to above German speaking countries, the technological and scientific background will be valid world-wide and can set new trends. The process and results can be presented in an oral presentation by the authors. (Stefan Esser, Silvester Siegmann, Helmut Ehnes, Claudia Budeck) The possible methodologies of the mental health assessment are described in detail as well as the social, legal and medical background of an international workforce.

Discussion- Conclusion

The specific challenges of people working abroad and the linked challenges of companies managing such people are explained and described. A focus lies on typical outcomes of such a mental health risk assessment and the counter measures to follow. The presentation finishes with an outlook to the vision zero and their link to mental health risks and offers very pragmatic checklists for companies who want to implement such mental health risk assessments in their organization.

Introduction

Solvay is committed to create a Sustainable Better Life for Employees, Communities and the Society at large.

Material and methods

We want to raise the bar in Health and Wellbeing to create a Sustainable Positive Healthy Organization, in coherence with Solvay Culture of Caring, focusing on the Human dimension as key for a sustainable business.

Results and Discussion

The aim is to create a Positive and Sustainable Better Quality of Life at work, not only by protecting the physical and mental health and preventing the risks, but going beyond and promoting health and wellbeing, making people’s life better thanks to the work at Solvay and therefore having also a positive impact in the Business, Community and Society.

Our approach relies on validated models from the Positive Organizational Psychology, coherent with Solvay Culture, as the Job Demand-Resource Model and the HERO (Healthy and Resilient Organization) Model. Similar approach is being developed in the European H-Work Project to promote Mental Health.

Being People-focused, we want to contribute to develop Healthy Employees (Engaged, Healthy, Resilient, with Trust), thanks to proven Healthy Organizational Resources (Autonomy, Feedback, Emotional competences, Positive and Inclusive Leadership, Team support) and Practices (Human Resources, Health, Safety, Social Responsibility, Communication); this will lead as a consequence to Healthy Organizational Outcomes (Performance, Commitment, Belonging, Authenticity, and less absenteeism, turnover and accidentability).

To make it happen, we have 3 pillars: 1) Governance at Group and Site level, with a Sponsor and a multidisciplinary Committee, 2) an Observatory with periodic diagnosis and indicators and 3) Positive actions multilevel.

Published: July 2024

Topic

Prevention and Rehabilitation of Work-Related Diseases in Healthcare Workers – An ISSA Session

Introduction

The previous study showed that supervisor support was associated with continuation of diabetes treatment. However, little is known about the association between Perceived Organizational Support (POS) and hypertension treatment. The present study examined the relationship between POS and seeking behavior of hypertension treatment.

Methods

This was a cross-sectional study conducted in March 2022 among employees aged 20 years or older using self-administered questionnaires. Out of 27,693 workers, 3,198 workers with hypertension were included in the analysis. The independent variable was POS score (0-48 points). The dependent variable was seeking behavior of hypertension treatment. We examined the relationship between POS and seeking behavior of hypertension treatment using logistic regression analysis. We adjusted age, sex, equivalent income, marital status, the number of employees in the workplace, and occupation as covariates. The study was approved by the Ethics Committee of the UOEH.^

Results

There were 2,215 (69.3%) in the treatment group and 983 (30.7%) in the non-treatment group. The higher POS score by one point, the higher the odds ratio of seeking behavior by 1.01, a significant difference. (p-value = 0.02)

Discussion

The study found that there was a statistically significant relationship between POS and seeking behavior of hypertension treatment. A previous study showed that high POS in the workplace is associated with workers’ participation in health behaviors.

Conclusion

High POS may encourage workers to participate in health measures implemented by the company such as a health guidance after health examination.
P-448 PROTOCOL FOR MONITORING EMPLOYEE’S HEALTH DURING INDUSTRIAL GLASS OVEN IGNITION
Authors: Mistreanu Anca , Chatealain Karine
Published: July 2024

Introduction

AGC Interpane’s (France) workers replaced a continuously operational glass furnace that had been in use for the last 25 years with a new, improved one.

Methods

This exceptional task exposed the workforce to a highly elevated thermal environment (up to 80°C), combined with heavy handling (sealing, manipulating refractory bricks, hand tools) and a fast pace to meet deadlines. During this operation the workers faced risks that could lead to acute pathologies that, in certain cases, rapidly threaten life: thermal burns, falls and traumas, dehydration, hyperthermia and its multi-organ consequences.

A working group consisting of occupational physicians and the company’s QHSE manager developed a protocol aimed at safeguarding the health of exposed employees. To organize prevention and specific medical monitoring for the personnel, the occupational physician planned the nature of the medical examination and additional tests in collaboration with chosen medical partners. The working group also formulated prevention proposals: collective and organizational protective measures, as well as individual.

Results and discussion

A 24/7 health coverage consisted of First Aid responders, an available occupational physician, nurses trained for the occasion by the occupational physicians and equipped by the company. The Emergency Department and Mobile Emergency and Resuscitation Service were informed about the anticipated types of pathologies, management protocols and evacuation procedures proposed to the nurses and First Aid responders.During the two ignition phases of the oven, employees presented pathologies such as heat stroke, syncope, thermal burns, hypertensive episode. None of them left a lasting sequela.

Conclusion

This first experiment revealed practical challenges that forced us to consider new solutions.
O-306 CONTRIBUTION OF WORK AND ORGANIZATIONAL PSYCHOLOGY TO PREVENT THE PSYCHOSOCIAL RISKS OF FISHERMEN
Authors: Laraqui Omar , Roland-Levy Christine , Deschamps Frédéric , Laraqui Chakib
Published: July 2024

The aim of this study was to identify the main causes of psychosocial risks (PSR) of fishermen, to analyze their consequences on health status and to assess the contribution of work and organizational psychology (WOP) in appropriate preventive strategies.

Methods

This was a systematic review of our studies that have focused on the assessment of the occupational health and safety in this sector, the stress, the fatigue, the burnout, the disorders of alertness and dyssomnias, the harassment, the risk-taking behaviors, the consumption of psychoactive substances, and the musculoskeletal disorders.

Results

The harmful effects of PSR on the psychological and physical health of workers are well established: psychosomatic manifestations, multiple chronic diseases, occupational accidents, compensatory behaviors, etc. The PSR are universal, however, our studies have the merit of raising and discussing a number of specific issues to Moroccan fishermen. Indeed, if the arduous and dangerous working conditions play the main role in the genesis of PSR, modulators can intervene to reinforce or weaken this influence. The WOP allowed us to articulate three levels of analysis of occupational fishermen: the fishermen’s work activity, the relationship between the fisherman and the maritime fishing sector, and the interpersonal relationships within the fishing sector. The WOP will enable the preventers to better analyze and explain the psychological processes involved in this activity. The assessment of these factors by prevention specialists (doctors, psychologists, etc.) enables an appropriate prevention strategy to be implemented.

Conclusion

An integrated prevention management system must encourage a planned, prioritized and graduated approach.
P-455 INDUSTRY GROUPS AS KNOWLEDGE BROKERS IN WORKPLACE MENTAL HEALTH: AN INTERNATIONAL SCOPING REVIEW
Authors: Burns Kristy , Amin Janaki , Ellis Louise , De Neto Abilio Almeida
Published: July 2024

Introduction

Industry-based intermediaries (including trade associations, peak bodies, professional associations, and unions), play a key role in improving occupational health and safety standards. While action from these groups to improve mental health has accelerated, these activities have not been systematically collated or evaluated. We aim to review mental health support activities being facilitated by industry intermediaries, mapped to the WHO Guidelines for Mental Health at Work.

Methods

The JBI methodology for scoping reviews was implemented. Sources included primary research and gray literature from 2010. We extracted and summarised (narrative and descriptive statistics), information including country, intermediary, program, target population, evaluation, and outcomes.

Results

2,597 records were identified for inclusion in the review, showing significant activity in this domain. According to the WHO guideline classification, most programs were classified as individual interventions or worker training. While the guidelines strongly recommend manager training, very few programs included this element. Most programs lacked an evaluation component.

Discussion

This study responds to calls from intervention researchers in occupational health to engage intermediaries in bringing about change. It highlights that industry groups are allocating extensive resources to improve worker mental health but cautions that key components are lacking or not documented, and their effectiveness is largely unevaluated.

Conclusion

An urgent need exists for industry groups to partner with workplace mental health experts to improve research knowledge transfer and increase the implementation of evidence-based interventions.
P-459 PSYCHOSOCIAL OCCUPATIONAL EXPOSURES AND MENTAL ILLNESS - A SYSTEMATIC REVIEW WITH META-ANALYSES
Authors: Seidler Andreas , Romero Karla , Freiberg Alice , Drössler Stephanie , Hußenöder Felix S , Conrad Ines , Riedel-Heller Steffi , Schubert Melanie
Published: July 2024

Introduction

The purpose of this study is to investigate the exposure-risk relationship between psychosocial occupational stress and mental illness. In many countries, the so-called doubling dose is important for the recognition of a new occupational disease: if a specific exposure is associated with a doubling of the risk of disease, it can be assumed — as a rule of thumb — that an occupational causation of this disease is more likely than unlikely.

Methods

We conducted a systematic review with meta-analyses as an update of a systematic review published in 2014. The study protocol was registered in PROSPERO (CRD42020170032). Literature searches were carried out in the MEDLINE, PsycINFO, and Embase databases. All procedural steps, including risk of bias assessment of included studies, were performed independently by two reviewers. Confidence of evidence was determined with the GRADE procedure.

Results

The pooled risk of depression was found to be approximately doubled in workers exposed to high job strain, which is defined as high work demands combined with low job control (effect estimate [EE] = 1.99, 95% CI [1.68; 2.35], heterogeneity [I2] = 24.7%, n = 8). In particular, high work demands are associated with incident depression (ES = 13.8 [1.19; 1.61], I2 = 69.0%, n = 9) and with incident anxiety disorder (ES = 1.79 [1.44; 2.23], I2 = 48.1%, n = 5).

Conclusion

High occupational strain is clearly associated with depression (GRADE: high confidence of evidence).

P-472 STRATEGIES AND THE USE OF TECHNOLOGY TO REDUCE SEDENTARY BEHAVIOR AMONG HOME-OFFICE WORKERS - RESULTS OF A DELPHI STUDY
Authors: Proper Karin , Loef Bette , Parés-Salomón Iris , Coffey Alan , Puig-Ribera Anna , Señé-Mir Anna , Vaqué-Crusellas Cristina , Dowd Kieran , Bort-Roig Judit
Published: July 2024

Introduction

Home-office based working is currently widely adopted. Recent evidence suggests that home-office working increases sedentarism and thereby may yield health problems. While digital solutions may enhance behavioural changes, there is a lack of research on the best strategies to reduce sedentarism in a home-office context. We explored the experts’ consensus about work policy strategies and the use of technology to reduce sedentary behavior (SB) among home-office workers.

Methods

A Delphi technique was used with 3 survey rounds among 29 experts from various countries worldwide. Participants were asked to rate the feasibility of work strategies for reducing SB when working from home, and to rate the usability of Behavioural Intervention Technology (BIT) elements. In the last round, strategies and BIT elements were matched.

Results

According to the experts, the most feasible strategies were: self-monitoring activity, creating an action plan and goal setting, scheduling short and active breaks, and offering real-time feedback and educational information. The most useful BIT elements identified in messaging and social support were gamification features including social challenges, while real-time data and data summaries were considered useful in the report and visualization category. Mobile phone diary and wrist-based activity trackers were found to be most useful for tracking activity. Both a mobile phone and a desktop application were considered useful to provide point of decision prompts and reminders for reducing sitting while working.

Discussion and conclusion

These findings provide valuable information for the development of a feasible and potentially effective digital intervention to reduce sedentarism during remote work.
O-317 OCCUPATIONAL EXPOSURE TO RADIOFREQUENCY ELECTROMAGNETIC FIELDS AND THE RISK OF BRAIN CANCER
Authors: Mate Rohan , Benke Geza , Loughran Sarah , Abramson Michael , Vajdic Claire , Karipidis Ken
Published: July 2024

Introduction

The relationship between exposure to occupational sources of radiofrequency electromagnetic fields (RF-EMF) and possible health effects has raised public concerns for many years, particularly for cancer incidence, including brain cancer. Exposure to RF-EMF is generally low, however for workers near certain RF-EMF sources, the exposure can be relatively high and be maintained for long periods. Previous studies have deficiencies in occupational RF-EMF exposure assessment and because of this have not been able to discount a possible association with health effects. Recently, two Job-exposure-matrices (JEM), the INTEROCC and CANJEM, have provided RF-EMF exposure information for 119 and 418 occupations respectively. These JEMs allow for a better-informed investigation of how occupational RF-EMF affects human health.

Methods

Using exposure data from CANJEM and lifetime occupational histories from the Australian Genomics and clinical Outcomes of Glioma (AGOG) case-control study, we investigated the association between RF-EMF exposure and glioma. The analysis used unconditional binary logistic regression to calculate adjusted odds ratios (ORs) and 95% confidence intervals (95%CIs).

Results

AGOG recruited 521 cases and 381 controls. We found no association between any RF-EMF exposure and glioma with OR=0.96 (95%CI 0.70-1.32).

Discussion

While the results do not support an association between RF-EMF and brain cancer, only CANJEM has been applied to-date. Analysis with the INTEROCC JEM will be undertaken upon completion of its construction. The two JEMs will also be applied to two further Australian case control studies investigating lymphoma and multiple myeloma.

Conclusion

Our preliminary results do not support a positive association between occupational exposure to RF-EMF and glioma.
P-473 CONTRIBUTING FACTORS TOWARDS IMPROVING RISK PRACTICES AMONG RESPONDERS FOR RADIOLOGICAL EMERGENCY PREPAREDNESS AND RESPONSE IN KLANG VALLEY, MALAYSIA
Authors: Rahman Anita Abd
Published: July 2024

Introduction

With radiation-advanced technology blooming in both medical and industrial businesses, this necessitates workers to be efficient in managing emergency response related to it. To ascertain the elements that affect responder risk practices, this study was carried out.

Methods

A cross-sectional study was conducted among respondents relevant agencies namely the regulatory, research, and services. Regression analyses were used to determine significant predictors of the outcome.

Results

The prediction equation model had seven independent variables with significant odds of having a high score of radiological risk practices. They were those working in radiological related organisation (aOR=3.662, 95% CI: 1.147, 11.692; p=0.028), risk perception (aOR=1.170, 95% CI: 1.024, 1.338; p=0.021), risk management proficiency (aOR=1.143, 95% CI: 1.037, 1.260; p=0.007), decision making (aOR=1.052, 95% CI: 1.001, 1.105; p=0.045), government evaluation (aOR=1.190, 95% CI: 1.100, 1.289; p<0.001), cultural values (aOR=1.176, 95% CI: 1.072, 1.291; p=0.001), and risk in context (aOR=1.061, 95% CI: 1.000, 1.127; p=0.049). This model was able to explain 57.9% of the variances of outcome variables.

Discussion

A more sustainable approach to lifelong learning and training is required, as evidenced by organizational, risk perception, decision making and radiation proficiency aspects. While doing so, it is possible to further incorporate government and cultural values as a part of total governance to foster the right culture among responders’ practices.

Conclusion

This study focused on factors that affected responder risk practices in radiological emergency preparedness and response. It was able to offer a wider perspective that can be taken into consideration as a potential area for enhancing radiological risk literacy.

Authors: Inselspital Anda-Petronela Radan , Iff Samuel , Cianferoni Nicola , Krieger Ralph , Arial Marc
Published: July 2024

Introduction

Pregnant and lactating women receive special protection at the workplace in Switzerland because of their increased vulnerability.

Methods

This cohort study investigated the subjective exposure to the presence of pre-defined dangers according to Swiss motherhood protection law, by work sector and other personal demographics using a representative Swiss dataset. 2’809 mothers replied to the questionnaire, of which 65% reported that occupational risks (OcR) at the workplace were present. 52% of the respondents were protected at the workplace according to the law.

Results

Factors negatively associated with implementation of maternity protection according to the law were: working in agriculture, trade and repair, hospitality industry, education, health and social work, arts, entertainment sports, cleaning, temporary employment, and private and other services, having compulsory education as the maximum qualification, working in French-speaking regions and working in small (1-9 persons) or medium-sized (20-49 persons) companies as well as suffering from health problems during pregnancy. Although 81% of mothers are either not exposed to OcR at the workplace or are protected by various measures, less than one-fifth of women with occupational risks were protected according to the law at their workplace.

Discussion

In addition, women reported a lack of information from their employers regarding risks and preventive measures especially in small and medium-sized enterprises.

Conclusion

Labour inspectorates should emphasize the importance of motherhood protection in small and medium-sized enterprises with OcR, focusing on risk assessment and implementation of corrective measures.
P-486 EFFECTS OF INTERNAL FACEPIECE PRESSURE SETTINGS TRIGGERING THE FAN OPERATION OF POWERED AIR PURIFYING RESPIRATORS (PART 1)—EFFECTS ON THE INTRA-FACEPIECE CARBON DIOXIDE CONCENTRATION
Authors: Kitamura Hiroko , Motokawa Yukako , Tahara Sayaka , Hyashi Hiroyuki , Hanaoka Saki , Noguchi Makoto , Horie Seichi , Kawanami Shoko
Published: July 2024

Introduction

Our previous study found that commercial powered air-purifying respirators (PAPRs) effectively protected against particles but retained high levels of exhaled carbon dioxide (CO2) gas within the facepieces. This study investigates the effects of internal facepiece pressure settings, which trigger the fan operation of PAPRs, on the intra-facepiece CO2 concentration.

Methods

Twelve healthy, non-smoking men participated in the study. Three types of breath-responsive PAPR were used: PAPR-A, having a higher pressure setting than a commercial model; PAPR-B, a commercial model; and PAPR-C, having non-fan operation. To mitigate order effects and exercise-induced fatigue, participants were randomly assigned to six groups. Participants wore each PAPR and exercised for 10 minutes at 40% of their maximal oxygen uptake while the intra-facepiece gas concentration was measured. This study was approved by the Ethics Committee of the University of Occupational and Environmental Health, Japan.

Results

During inhalation, the intra-facepiece CO2 concentration decreased in the order of PAPR-C, PAPR-B, and PAPR-A, with the mean values for each individual ranging 2.1%–5.0%, 1.6%–4.0%, and 1.6%–3.1%, respectively.

Discussion

Increasing the internal facepiece pressure setting improved the intra-facepiece air quality. This improvement is attributed to the longer fan operation, which increased the air supply and enhanced ventilation within the facepiece. However, a disadvantage of a higher pressure setting was a shorter operating time of the battery powering the fan.

Conclusion

A higher internal facepiece pressure setting was found to be effective in maintaining an appropriate intra-facepiece CO2 concentration compared with a commercial model. The development of smaller longer-lasting batteries is expected.
P-488 EFFECTS OF INTERNAL FACEPIECE PRESSURE SETTINGS TRIGGERING THE FAN OPERATION OF POWERED AIR PURIFYING RESPIRATORS (PART 2)—EFFECTS ON SUBJECTIVE SYMPTOMS

Published: July 2024

Introduction

Our previous study found that humidity within a facepiece affects the feeling of stuffiness when respiratory protective equipment is worn. It was suggested that using powered air-purifying respirators (PAPRs), which provide air within the facepiece, alleviates this stuffiness. The present study investigates the relationship between the pressure settings triggering the operation of PAPRs and subjective symptoms.

Methods

The study involved 12 healthy, non-smoking men. We prepared three types of PAPR (i.e, PAPR-A: a respirator with a pressure setting higher than that commercially adopted, PAPR-B: a respirator having a commercial setting, and PAPR-C: a respirator having no operational fan). To mitigate order effects and exercise-induced fatigue, participants were randomly assigned to six groups. Subjective symptoms during exercise were measured using the visual analogue scale (VAS). The study was approved by the Ethics Committee of UOEH.

Results

The mean VAS values for intra-facepiece stuffiness were 4.67 (PAPR-A), 4.75 (PAPR-B), and 6.58 (PAPR-C). Significant differences were observed in the feeling of stuffiness within the facepiece between PAPR-A and PAPR-C and between PAPR-B and PAPR-C but not between PAPR-A and PAPR-B. Similar results were obtained for other subjective symptoms, namely difficulty in breathing, hotness within the facepiece, and discomfort.

Discussion

Considering our other finding that the intra-facepiece carbon dioxide concentration improved with enhanced ventilation, the observed improvements in subjective symptoms are also attributed to this enhancement. The improvement in subjective symptoms is thought to contribute to workers’ willingness to wear appropriate protective equipment.

Conclusion

Increasing the internal facepiece pressure setting of the PAPR improved subjective symptoms.

Introduction

There is unmet need in novel predictors of occupational chronic obstructive pulmonary disease (COPD) for risk management improvement. The aim of the study was to investigate the inflammatory factors associated with exposure of nanoparticles – the less investigated industrial aerosols’ component, and reveal potential risk markers.

Methods

It was a prospective observational study. Nanoparticles at workplaces air in a machine manufacturing facility were investigated by scanning electron microscopy and inductively coupled plasma atomic emission spectrometry. Participants were 250 employees (97,2% males, 2,8% females aged 51 (46-55) years, healthy at the time of inclusion) worked at the investigated workplaces. Monocyte subpopulations was measured by flow cytometry, serum cytokines by ELISA. Spirography was done every 6 months for 36 months. COPD was diagnosed by GOLD criteria. Relationships were measured by Cox proportional hazard and linear regression.

Results

Silica nanoparticles were predominant, their mass concentration was 0.035 (0.028-0.042) µg/mL. It was 31 (12.8%) COPD cases during follow up. In multivariate analysis (OR, 95% CI) CD14DimCD16+ monocytes (2.45, 1.003–6.001), fibroblast growth factor-2 (FGF-2) (9.61, 2.081–44.399), soluble vascular cellular adhesion molecule-1 (sVCAM-1) (1.49, 1.243–1.939), amino-terminal propeptide of type-III procollagen (PIIINP) (1.3, 1.070–1.570), matrix metalloproteinase-9 (MMP-9) (1.23, 1.023–1.470) were associated with COPD development. All these molecules were associated with silica nanoparticles mass concentration (p<0.010).

Discussion

Perspective COPD predictors were established. Further validation is needed to develop the prognostic scale.

Conclusion

Percent of non-classical monocytes, serum levels of FGF-2, sVCAM-1, PIIINP and MMP-9 are perspective predictors of COPD within the next three years in workers exposed to aerosols, containing silica nanoparticles.

Published: July 2024

Introduction

Occupational exposures are an important cause of chronic obstructive pulmonary disease (COPD). This work aims to analyze the epidemiological evidence on the association between occupational exposures, the development and aggravation of COPD, with a particular focus on Morocco.

Methods

Scientific databases were searched for studies reporting data on COPD and workplace exposures.

Results

Data from the published literature show that occupational exposures play an important role in the development of COPD. Positive correlations have been established between occupational exposures and the prevalence and incidence of COPD. In addition, occupational exposures have a negative impact on COPD patients, resulting in increased frequency of respiratory symptoms and exacerbations, reduced spirometric parameters and impaired quality of life. In Morocco, the link between occupational exposure and COPD has not been sufficiently studied.

Discussion

A limited number of studies have suggested that construction workers and former miners are at high risk of developing COPD. No studies investigating the effect of occupational exposure to dusts, vapors, gasses and fumes on the health status of COPD patients in Morocco were found.

Conclusion

Occupational exposure is a potential risk factor in the development and aggravation of COPD. In Morocco, this link has not been sufficiently studied. Consequently, it is time for more in-depth studies aimed at identifying at-risk occupations, assessing the exposure-response relationship, and determining the exposure limits that should be retained to guide COPD prevention and management strategies nationwide.
P-499 ACCELERATED SILICOSIS IN A STONEMASON – HOW MANY CASES DO WE NEED TO LEARN THE LESSON?
Authors: Handra Claudia- Mariana
Published: July 2024

Stonemasons are at high risk of silicosis: they generally work on a contract basis, in small enterprises, with minimal protective measures and due to frequent changes in employers might skip the continuity of an occupational medicine surveillance.

We present a case of a 32 years old men, who was heavily exposed to natural stones (including granite) as stonemason for 9 years and was never refered to a specialized clinic of occupational medicine for the mandatory annual checkup. He start working since he was 16 years old in a small workshop. The main activities were cutting, griding and polishing natural stones without protective equipment and no aspiration system.

In 2016 he was admitted in a pulmonology clinic for dispnea, mialgia and arthralgia.. This diagnosis of tuberculosis was ruled out after several negative sputum results. Lung and mediastinium ganglia biopsies were performed and confirmed the presence of the silicotic nodules and extensive fibrosis.

He was treated with systemic corticoid for cough and dyspneea exacerbation, but the clinical status progressively deteriorate. In 2022, he had a spontaneous pneumothorax. In June 2023, due to the severe mixed ventilatory disfunction (FVC=26%, FEF1 =16% and FEF1/CV = 50.4%, TLC = 37%), DLCO=5.77 mmHg (16%) he was proposed for the pulmonary transplant.

This case highlights the need for prevention in small enterprises and the desastrous consequences of ignoring the exposure. This message has to pass to employees and employers, authorities and all the ones involved in occupational risk management in order to stop cases like this one to happen.

Introduction

Occupational use of pesticides is responsible for health effects and improvement of prevention needs to better define exposing tasks and associated exposure levels. In agriculture, exposure during the handling of pesticide-coated seeds is unknown.

Methods

35 volunteer farmers were monitored during the sowing of coated cereals. Fludioxonil and prothioconazole fungicides were quantified by HPLC MS/MS in patches representing 11 body zones, placed under and over the clothing, in order to estimate potential and actual dermal exposure. XAD-2 filter was added for the respiratory route.

Results

90% of measurements were over the limit of quantification (> 0,015 µg) and revealed large interindividual variations. Dermal exposure levels were higher at preparation of the seeder than after sowing in the field. During preparation of corn sowing, wearing gloves decreased exposure, while rolling empty seeds bags on the thighs increased it. For straw cereals, the filling time, emptying or adjustment of the seeder increased dermal exposure too. In the field, strongest exposures concerned operators who regularly got off of the tractor and/or kept the cabin closed. Respiratory route was generally far lower.

Discussion

For the first time, a low but systematic dermal exposure during sowing is highlighted. Measured levels remain below other activities such as pesticide application. However, as sowing is repeated over a season time, cumulative exposures have to be more considered.

Conclusion

Contrary to what is generally accepted, sowing with coated seeds exposes operators to pesticides. First identified determinants would be good levers for prevention.

Introduction

Exposure to pesticides in Arab countries poses a significant public health concern, given the extensive agricultural activity and pesticide utilization.

Methods

This systematic review and meta-analysis study aims to assess the genotoxic effects of agricultural pesticide exposure on adult agricultural workers in 19 Middle Eastern countries, identify research gaps, and evaluate methodological constraints. The study protocol, registered as CRD42022314453, conducted a comprehensive database search in PubMed, Scopus, Web of Science, Embase, and Agricola without language restrictions, adhering to PRISMA 2020 guidelines and a structured PECO statement for study selection.

Results

This search identified just five relevant studies within Egypt, Syria, and Jordan. We assessed the Risk of Bias using a comprehensive tool that aligns with WHO/ILO Joint Estimates and incorporates principles from the Navigation Guide RoB tool and RoB-SPEO domains. Furthermore, we conducted a quantitative meta-analysis on homogeneous data. The results of various genotoxicity assays consistently demonstrate a heightened level of DNA damage in individuals exposed to pesticides compared to their non-exposed counterparts. Notably, farmers exposed to pesticides exhibit a significantly increased occurrence of chromosomal translocation (t(14;18)), micronuclei formation, and chromosomal aberrations. It is noteworthy, however, that only two of these studies assessed cytotoxicity indirectly.

Discussion

In addition, the limited availability of detailed exposure data necessitates a cautious interpretation of the findings. This review underscores the imperative for further research on the genotoxicity of occupational pesticide exposure in the Middle East.

Conclusion

By deepening our understanding of the genotoxic effects of pesticide exposure, we can develop more effective strategies to safeguard the health of agricultural workers in Arab countries.

Introduction

In Spanish agriculture, thousands of foreign workers are hired each year to collect fruits and vegetables. The AGROMISALUD project aims to describe the working conditions of agricultural workers from Magreb and Subsaharan Africa in Spain.

Methods

A multicentre cross-sectional descriptive study was conducted in 4 Spanish regions in 2022. A 43-question questionnaire was designed. Descriptive statistics (frequencies and percentages) were calculated in STATA.13.

Results and discussion

623 agricultural workers (65% men, 34% women) from 21 countries on the African continent were surveyed: 62% North African and 38% sub-Saharan. 40% of the men and 88% of the women were from Morocco. 14% (19%men,5%women) of the sample used chemicals, flammable liquids and gases. 29% (35% men,7%women) had received information or courses on occupational hazards from the company or employer. 46% (60%men,18%women) lifted, carried, or pushed heavy objects of more than 20 kg or more manually at least 10 times a day. 48% (61%men,21%women) did not have the necessary protection such as gloves, masks, helmets, and 54% (50%men, 61%women) did not know their rights and responsibilities about their health and safety at work.

Conclusion

Migrant agricultural workers in Spain need to receive both the required material to prevent injuries at work and information and/or courses on occupational hazards from the company or employee.

Introduction

The use of pesticides plays an important role in agricultural-production. However, pesticides are also used in non-agricultural settings, where they can impact on occupational and community health. This study aims to explore the use of herbicides in non-agricultural settings, starting from the railways sector, by outlining in particular the role of regulatory and technical approach related to a sustainable use of pesticides in the EU.

Materials and methods

The study concerned the analysis of EU-legislation on pesticides (Directive 2009/128/EC) and its implementation in Italy, as well as the analysis of herbicides distributed in Italy along the time and, among these, those specifically authorized for non-agricultural use. For this analysis, we used the ISTAT and the Italian Ministry of Health databases.

Results

The preliminary analysis of herbicides sales trend showed an overall decrease over the last years, probably due to the 2009 regulatory package for the sustainable use of pesticides; nevertheless no specific data on non-agricultural use are extractable. The analysis of chemical classes of herbicides revealed that in Italy those allowed for railways essentially derive from research developed in the agricultural sector, thus potentially implying similar aspects of health and safety for workers, the environment and surrounding communities.

Conclusions

The lack of specific data on non-agricultural herbicides, resulting from their non-exclusive authorization, makes it very difficult to quantify their use. The results show the need to improve the information flow on sales and use it to fill this gap for a complete picture of the potential impact of herbicides on workers and the population.

Published: July 2024

Introduction

Presenteeism is a condition in which an employee is unable to perform adequately due to physical or mental health problems despite being present at work. Although the previous study has shown that presenteeism is associated with near misses, the limitations are that it is a cross-sectional study and the subjects are limited to first responders. This study aims to investigate the relationship between presenteeism and occupational accidents.

Methods

The study design was a prospective cohort study with a baseline survey in March 2022 and a follow-up survey one year later. The independent variable was presenteeism at baseline using WHO-HPQ, classified into four categories. The outcome was the occurrence of occupational accidents from baseline to follow-up. We examined the relationship between presenteeism and occupational accidents using logistic regression analysis. This study was approved by the Ethics Committee of UOEH.

Results

Among 16,629 workers, presenteeism was “0-50%” (n=5,490); “60-70%” (n=5,235); “80%” (n=3,711); and “90-100%” (n=2,193). The odds ratios of each group were 1.46 (95%CI, 1.21-1.77), 1.13 (0.93-1.37), and 1.13 (0.92-1.39), respectively, compared to “90-100%”.

Discussion

Presenteeism may have reduced concentration and judgment, which in turn increased the risk of occupational accidents. The countermeasure for presenteeism may be effective in reducing the risk of occupational accidents.

Conclusion

Presenteeism was associated with the occurrence of occupational accidents.
O-348 BEHIND THE TIMES? ASSOCIATIONS OF WORKING TIME AUTONOMY WITH PSYCHOSOMATIC COMPLAINTS IN HEALTH CARE PERSONNEL
Authors: Riedel-Heller Steffi G , Pabst Alexander , Luppa Melanie , Jung Franziska U
Published: July 2024

Introduction

Flexibility and autonomy of employees with regard to working hours are currently intensively discussed in many sectors. This study investigates how different aspects of working time autonomy are associated with health outcomes such as psychosomatic complaints in health care personnel.

Method

Based on data of the German BAuA Working Time survey, a sample of n = 1,093 employees working in the health care sector were included. Working time autonomy was assessed with five Likert items, psychosomatic complaints during the last 12 months with a complaint list. A latent class analysis (LCA) was conducted to identify distinct classes of health care workers with patterns of more or less autonomy. The association with psychosomatic complaints was investigated using generalized linear models.

Results

Sample Description reveals a mean age of 51.1 year (SD 9.7), 25.3% were female. Psychosomatic health complaints ranged from 0 to 11, with a mean of 4.1 (SD2.9) and stomach discomfort or indigestion, shoulder or neck pain and lower back pain being reported most often. The LCA revealed that three latent classes fitted the data best: 43.9% of health care workers showed a predominantly low, 37.9% medium and 18.1% high degree of working time autonomy. Adjusted for confounding, those with low degrees of autonomy had on average a significantly increased number of psychosomatic complaints, while those with a high degree of autonomy had a reduced number of psychosomatic complaints.

Discussion

The analyses indicate that it is crucial to prospectively consider working time autonomy as an important factor of health and well-being in health care employees.

Authors: Laraqui Omar , Manar Nadia , bouri Hicham El , Deschamps Frédéric , Laraqui Hossini Chakib
Published: July 2024

Introduction

The aim of this study was to assess the impact of Ramadan on sleep and alertness in healthcare professionals working in intensive care units.

Method

This cross-sectional epidemiological study involved 152 people (96 on-call and 52-day shift). A self- questionnaire was administered during the third week of Ramadan and the third week after the end of Ramadan. It included socio-demographic and professional data, lifestyle and sleep habits, sleeping and alertness disorders (Epworth scale) and fatigue (Pichot scale).

Results

During Ramadan, changes in dietary and lifestyle habits were reflected in shifted sleep and wake-up schedules. Mean nocturnal sleep duration was 5.9 ± 1.3 h during Ramadan, compared with 7.1 ± 1.5 h after Ramadan. During Ramadan, 46% woke up feeling tired and sleepy, and 53.3% had a headache, compared with 28.3% and 19% respectively after Ramadan. The prevalence of napping increased during Ramadan: 42.1% versus 29.6% after Ramadan. The prevalence of sleep disorders, daytime sleepiness (Epworth > 10) and fatigue (Pichot > 22) was higher during than after Ramadan (79.6%, 86.2% and 44.1% vs. 63.2%, 53.3% and 13.8% respectively).

Discussion

These differences in prevalence were more marked among on-call caregivers than among those working during the day. The prevalence of regular sports increased slightly during Ramadan, while the prevalence of harmful habits remained unchanged, with the exception of alcohol, whose prevalence was zero.

Conclusion

occupational medicine in the hospital sector has an important role to play in raising caregivers’ awareness of the risks associated with bad practices adopted during the month of Ramadan.
P-519 PERCEIVED FATIGUE AND SLEEPINESS AMONG BRAZILIAN AIRLINE PILOTS
Authors: Sampaio Izabela Tissot Antunes , Leandro José , Chiann Chang , Fischer Frida Marina
Published: July 2024

Introduction

Fatigue management rules for civil aviation have changed since 2019 in Brazil. One of the aims of this study was to assess perceived fatigue and sleepiness of Brazilian airline pilots.

Methods

Fifty-one airline pilots participated. They scored perceived fatigue and sleepiness three times a day, during 15 consecutive days, along working days and off-days using Samn-Perelli Scale-SPS and Karolinska Sleepiness Scale-KSS. A total of 3,434 records was analyzed using a binomial mixed effects model with logit link according to duty starting times: night (00h00-06h00), early morning (06h01-07h59), morning (08h00h-12h00), afternoon (12h01-17:59) and evening (18h00-23h59). This study was approved by the Ethics Committee of University of Sao Paulo (36370720.9.0000.5421).

Results

Perceived severe fatigue (scores 6,7 in SPS) was higher during nighttime work when compared to those starting in the morning (three times the odds), afternoon (six times) and evening (four times). Early starts also presented higher odds for severe fatigue than afternoon (five times) and night (three times) periods. Perceived excessive sleepiness (scores 7,8,9 in KSS) followed similar trends, but was also higher in the evening when compared to afternoon (three times the odds), in the morning compared to afternoon (twice the odds) and at night compared to early morning (twice the odds).

Discussion and conclusion

The most perceived disruptive schedules were those that included nighttime and started early in the morning, both for severe fatigue and excessive sleepiness; and those that started during evening hours for excessive sleepiness. Safety barriers to effectively manage those working times are needed.
