Abstract

Introduction
Lung cancer is considered the most common occupational cancer. The aim of this study is to identify the occupational exposures responsible for primary lung cancer in patients from southern Tunisia.

Methods
Any incident of primary bronchial cancer in the Pneumology Department of the CHU Hédi Chaker in Sfax was included in the study. Exposure to occupational respiratory carcinogens was investigated on the basis of a standardized occupational questionnaire. If the various conditions set out in the list of the Tunisian tables of occupational diseases were fulfilled, a declaration of occupational disease was made.

Results
Our study lasted one year and included seventy patients. Our sample was predominantly male (94.28%). Mean age was 62.81 ± 9 years. The proportion of smokers or ex-smokers was 94.30%. The most frequent histological type of lung cancer was adenocarcinoma (44.2%). Occupations were manual in 95.60% of cases. Construction (35.29%) and agriculture (23.52%) were the most common sectors. Occupational exposure to a respiratory carcinogen was noted in 65% of cases. The most frequently encountered carcinogens were crystalline silica (17.64%) and diesel exhaust (13.23%). Four patients were considered to suffer from a compensable occupational disease.

Discussion
Lung cancer is the most common form of occupational cancer. However, under-reporting may represent unrecognized injuries that especially burden precariously employed workers as financial, health and social.

Conclusion
The medico-legal management of lung cancer can lead to a more effective policy of identifying occupational exposure to lung carcinogens.

Abstract

Introduction
Silicosis is a pneumoconiosis resulting from the inhalation of respirable crystalline silica (RCS). It is widely acknowledged that occupational exposure to RCS occurs in various industries. In occupational health practice, silicosis is mainly detected when the disease is already advanced. Early detection of RCS-exposure is necessary to assess the exposure risk and prevent possible lung damage. This observational study aims to validate a simple, non-invasive diagnostic breath test for the early detection of silicosis in an at-risk population by correlating breath analysis with inflammatory blood markers.

Methods
After informed consent voluntary participation of patients with diagnosed silicosis (n=±25) includes questionnaire assessment, breath and blood sampling and spirometry. To optimize the validity, this test set will be compared with a population with COPD (n=±25), asbestosis (n=±25), healthy unexposed (n=±25) and asymptomatic RCS-exposed (n=±75) controls. Ion mobility spectrometry will be used to identify volatile organic compounds (VOC). Multivariate analysis will be performed. ROC curves will be calibrated.

Results
If the presence of RCS alters physiological processes in the body through chronic inflammation, it is expected that these changes in the metabolic status can be reflected through changes in the breath profile and thus can be used as a screening tool for silicosis.

Discussion
Inconsistent analytical methodology in previous research precludes decision-making on findings that breath analysis results in a VOC-signature for pneumoconiosis. Therefore, large-scale studies including simultaneous assessment of blood and exhaled breath markers are needed.

Conclusion
By mapping specific biomarkers present in silica-associated pulmonary disease, risk assessment in occupational health settings could be improved.
P-507 RURAL HEALTH AND DECENT WORK: VULNERABILITY IN LOW AND MIDDLE-INCOME COUNTRIES (LMIC) AND MONOCULTURE PRODUCTION
Authors: Messias Iracimara , Galvanin Edineia , Silva Elias 
Published: July 2024

Abstract

Introduction
Large-scale food production, such as monocultures in low and middle-income countries (LMIC), presents both known and new hazards that impact decent work, objective of sustainable development. Workers in LMIC are more exposed due to less stringent laws and vulnerability to the benefits of large Multinational Corporations (MNC’s). The use of pesticide no longer used in developed countries, exposes families of rural workers in LMIC. The pesticides are used in the production of sugarcane monoculture for sugar and ethanol production. The study provides evidence of the impacts of sugarcane monoculture expansion on the work, environment, and health of peasant families.

Methods
An empirical study was conducted with a theoretical framework based on Cultural-Historical and Activity Theory (CHAT). Temporal maps were developed over a twenty-year period (1999 to 2019), in a recognized sugarcane monoculture-producing region in Brazil.

Results
We observed the substitution of livestock production with sugarcane monoculture. Evidence of environmental degradation was observed, such as pollution of sources and tributaries in the Paranapanema River Watershed, as well as the impacts on climate change. Additionally, due to pesticide spraying in the monoculture plantation areas, peasant’s families of neighboring these areas have their agroecological production affected and compromised.

Discussion and conclusion
The existing contradictions in biofuel production and the real impacts on rural work, the environment, and health of the population, especially peasant agroecological families, make these workers vulnerable and distant from decent rural work in LMIC.

Published: July 2024

Abstract

Introduction
In Morocco, due to the lack of education and the presence of a counterfeit and illegal market, pesticides constitute a major problem to be addressed by occupational and environmental health. Growing evidence suggests a link between pesticide exposure and epigenetic changes, including DNA methylation variations. In this context, we aim to examine comprehensively whether multi-residue exposure to commonly used pesticides could induce epigenetic alterations.

Methods
The PaPOE project includes a cross-sectional study assessing the occupational exposure among 322 farmworkers and pesticide appliers in Fez-Meknes Region (Morocco). Survey questionnaires have been conducted between 2018 and 2022 to assess pesticide exposures and work practices of the farmers. Urine and blood were collected. The biomonitoring approach using LC-MS and GC-MS targeted the profiling of 28 pesticides and their metabolites in urine. Oxidative stress biomarkers include GSH and 8-OHdG. Global DNA methylation is performed using LC-MS in blood.

Results
Overall, knowledge was significantly associated with education level and previous training on pesticide use, while health risks were significantly associated with the use of PPE. Pesticides were detected in 77% of samples, with mainly organophosphates and organochlorines. Glutathione and 8-OHdG were significantly associated with pesticide exposure. Global DNA methylation status is altered in the pesticide-exposed population compared to the non or less-exposed group.

Conclusion
Our study paves the way for a biomonitoring system in Morocco to assess environmental and occupational exposures and to provide insight into the long-term course and potential health consequences of pesticide exposure.
O-339 TITLE: GESCOCRISE HEALTHCARE, A SERIOUS GAME TO LEARN THE COLLABORATION BETWEEN STAKEHOLDERS TO MANAGE CRISIS
Authors: Caroly Sandrine , Fischer Juliette , Peisser Carine , Barbois Sandrine , Arvieux Catherine 
Published: July 2024

Abstract

Aim
This serious game allows students in healthcare or risk prevention to understand the collective management of a crisis linked to a natural hazard. By playing an actor, it is possible to represent the needs of the others. The communication between experts (surgeon) and other stakeholders (local authorities, directors of hospitals, rescue service, general physician) appears essential as a means of collectively managing the situation with domino effect, cascading on the healthcare system.

Methods
The participants are 51 students in 3 groups. They played the game, which takes place in two steps (start of event, cascade effect). They are assigned to play one of the game’s actors with instructions on the context and their role. In step 1, they choose what they do as an actor. In step 2, they must interact with other players to develop a collective management of the crisis. A questionnaire before and after the game permits them to assess their knowledge.

Results
All participants learn about the role of different stakeholders. They refer to the actor’s technical role at the start of the game and then to a more communicative role for the same actor at the end. In step 2, the communication increases between the various players, going well beyond the expected formal interactions between stakeholders.

Discussion
To prepare for crisis management, it’s important to develop collective skills and understanding of the role of all stakeholders in the healthcare system.

Conclusion
Serious game design and assessment are theoretical and methodological challenges for learning and risk anticipation.
O-342 INVESTIGATING THE RECIPROCAL EFFECTS; THE RELATIONSHIP BETWEEN EMOTIONAL EXHAUSTION AND DEPRESSION WITH THE ROLE OF PSYCHOSOCIAL SAFETY CLIMATE
Authors: Afsharian Ali , Loh May , Crispin Cherie , Dollard Maureen 
Published: July 2024

Abstract

Background
In this four-wave longitudinal study, we aimed to investigate the relationship between emotional exhaustion and depressive symptoms and their connection to the psychosocial safety climate (PSC). Previous studies have shown that PSC plays a crucial role in the psychological well-being of workers, as an extension of the job demands-resources (JD-R) model. However, this study specifically focused on the moderating role of PSC and the reciprocal effects of emotional exhaustion and depressive symptoms over time.

Methods
This study used the Australian Workplace Barometer data, monitoring workplace psychosocial factors using population-based random sampling since 2009. The Australian sample comprised 415 workers aged 18-65 from various industries, with complete data across four waves spanning 11 years. Participants received an introductory letter and were contacted via a CATI system and interviewed. Data was weighted for age and gender factors and analyzed using SPSS-28 and Mplus-8.

Results
According to our research, there is a clear connection between self-reported emotional exhaustion and future depressive symptoms. We also found that PSC is negatively related to both of these factors over time. Additionally, we observed that emotional exhaustion has a stronger reciprocal effect on depressive symptoms, and we anticipate that PSC will further weaken this relationship over time.

Conclusions
Preventing depressive symptoms can be achieved by addressing risk factors such as emotional exhaustion at work and emphasizing the critical role of the corporate climate, specifically PSC. Workplaces should prioritize improving PSC to reduce the negative impact of emotional exhaustion and break the cycle of adverse effects.
P-514 AN ANALYSIS OF THE SAFETY CLIMATE OF OUTDOOR LANDSCAPE WORKERS
Authors: Kearney Donal , Buggy Conor , Paiboon Lij Pen Patra Sri 
Published: July 2024

Abstract

Introduction
Outdoor Landscape workers’ awareness towards the safety climate in their workplace was analyzed by their responses to a self-administered questionnaire. Those that partook were full-time and part-time in their professional status and had been working outdoors for different lengths of time. The objective was to examine the attitudes towards safety and the levels of safety climate awareness in full-time and part-time workers with varying years of experience.

Methods
A cross-sectional study of Outdoor Landscape Workers in which 115 workers participated in an anonymous questionnaire survey. Data analysis was carried out using descriptive statistics. An analysis of Outdoor Landscape Workers’ attitude towards safety in their workplace was analyzed from their responses.

Results
Full-time workers and those with more years’ experience responded that they believe a significant number of Outdoor landscape workers are prone to being hurt and that there is also careless behavior among their fellow workers that do not follow safety rules.

Discussion
The study is a snapshot in time and the results corroborate with previous studies. The behavior of workers is arguably subjective, and their views are determined by their work environment. The primary data results are an indication of what workers believe to be the case on how safety is managed in their workplace. Positive responses are associated with part-time workers aspirations to progress onto full-time employment which correlates from those with less years’ of experience in this type of employment.

Conclusion
The study shows the relationship between length of employment and job position (full-time or part-time) and safety awareness in the workplace.

Abstract

Introduction
Working during the night interferes with the timing of normal daily activities and it is associated with an increased risk for several chronic diseases. Interventions focused on nutrition and sleep can mitigate the short-term adverse effects of shift work under controlled experimental conditions. However, it is unclear how these results translate to real life, and relate to long-term health. Therefore, the current study aims to implement a personalized sleep and nutritional intervention among night shift workers and to evaluate its effect on various health outcomes.

Methods
This non-blinded controlled intervention study evaluates various health outcomes at baseline, at the start and end of a 3-month intervention, and at a 1-year follow-up. Three study arms are included: nutritional intervention, sleep intervention, and control group (n=25 each). Participants are healthy 18-60-year-old men, working 12h shifts (18:00-6:00 or 6:00-18:00). The intervention is a personalized sleep or nutritional advise based on sleep information (using ActiWatch and sleep diaries), continuous glucose measurements, food diary, and questionnaires collected during the baseline period. This study was approved by the Medical Ethical Review Committee of Erasmus University Medical Center.

Results
In this ongoing study main outcomes are objective and subjective sleep measurements and continuous interstitial glucose levels. Furthermore, biomarkers and general (mental) health parameters are determined to further evaluate effects on indicators of long-term health.

Discussion and conclusion
This study aims to make a meaningful contribution to the translation of findings from controlled experimental conditions to a real-life setting, with the ultimate goal to improve long-term health in night shift workers.
P-523 THE RELATIONSHIP BETWEEN STRESS AND SAFETY AMONG NURSES DURING COVID-19 AND THE PRESENCE OF OCCUPATIONAL BURNOUT
Authors: Afnan Heno 
Published: July 2024

Abstract

Introduction
Burnout is one of the primary phenomena that affects not only nurses, but the entire healthcare system. The research objective is to investigate the relationship between stress and safety among nurses during COVID-19 and the presence of occupational burnout.

Methods
The research is a Cross-Sectional Study and included nurses employed in Clalit health services in Haifa and Western Galilee districts.The sample consisted of 115 nurses (95% CI) with a 5% margin of error. The study’s power was 85%. Potential participants were contacted through an internal distribution list and received links to online questionnaires via email. By completing the questionnaire, they gave their consent to participate in the study. The research included socio-demographic, job stress, health and safety, and burnout questionnaires.

Results
A significant positive correlation existed between perceived stress among healthcare workers during the pandemic and their risk of experiencing occupational burnout. Another significant positive correlation was found between health behaviors during COVID-19 and the presence of burnout among the research participants. However, no statistically significant difference in the average level of burnout was observed between nurses who smoked or started smoking during COVID-19 and those who did not.

Discussion
The study demonstrated that lower perceived job safety and higher workload were associated with higher levels of burnout.

Conclusion
One significant conclusion is the positive association between nurses’ stress levels during COVID-19 and their risk of experiencing occupational burnout. Overall, the research showed that the pressures and demands faced by healthcare workers during a global health crisis can significantly contribute to burnout.
P-524 EVALUATION OF METHODS FOR ACCURATELY MEASURING WORKING HOURS OF PHYSICIANS AT THE UNIVERSITY HOSPITAL
Authors: Nagano Chikage , Kohi Shiro , Kado Kentaro , Funada Midori , Goto Motohide , Horie Seichi 
Published: July 2024

Abstract

Introduction
In 2016, 3 cardiovascular deaths and 2 psychiatric diseases of physicians were covered by workers’ compensation insurance in Japan. Currently, there is no limit of working hours for physicians; however, their health condition is also important to keep the quality of medical practice. Therefore, the relevant legislations were revised and will start to limit working hours of physicians from 2024. Some tough questions awaited are the need to keep records on working hours including that at side jobs and to differentiate self-intended education, training, or research activities from required work. We measured physicians’ working hours using several subjective and objective methods, and examined the existence and causes of their discrepancies.

Methods
The working hours per week of 5 physicians working at university hospitals were measured and compared using the following

method
(1) Records of working hours submitted to the attendance management department, (2) Records of entry and exit by ID card, (3) Records of entry and exit by GPS measuring device, (4) Records by participating physicians themselves.

Results
The working hour only at their main job was 82.4 ± 25.9 (mean ± SD) hours according to their self-records but was 98.8 ±30.3 hours by ID card. The difference was 11.5 ±10.8 hours. The length of self-intended activities was 15.0 ± 22.9 hours including two physicians reported zero.

Discussion
As most physicians have side jobs, it would be more difficult to measure their working hours accurately.

Conclusion
Occupational health services must recognize these differences at their health interviews.
O-358 RISK ASSESSMENT IN STANDING WORKPLACES: EXTENSION OF A MULTIDIMENSIONAL MODEL FOR PREDICTING LOWER LEG OEDEMA DURING STANDING WORK
Authors: Steinhilber Benjamin , Volk Carmen , Wagenblast Florestan , Seibt Robert , Gabriel Julia , Ulmer Luis , Rieger Monika A 
Published: July 2024

Abstract

Background
Standing work is associated with lower leg venous disease, and lower leg oedema is discussed as a surrogate for increased health risk. Prolonged standing (≥2 h) increases lower leg oedema but not walking. On this basis, a model for predicting lower leg oedema was developed to assess venous health risks in standing workplaces. As short interruptions by temporary sitting are common, the aim of the study is to compare the effect of sitting and standing and alternating between standing and sitting on lower leg oedema.

Methods
28 adults (15 women; mean age = 40 years) participated in a laboratory experiment. On one day, they stood for 3 h followed by 2 h of sitting (exposure A); on another day they sat for 3 h and followed by 2 h of walking (exposure B). The order of the exposures was randomized. Differences in oedema during standing, sitting and walking were measured by bioelectrical impedance.

Results
Sitting induced lower leg oedema but to a lesser extent than standing. Sitting after 3 h of standing leads to a further increase in oedema, whereas walking after sitting leads to a reduction.

Discussion and conclusion
Sitting should be considered as another factor in the model for predicting lower leg oedema. In a first step, these findings will be used to extend the risk assessment model. In a second step, the model will be validated in a field study in order to provide a tool for risk assessment of venous disease in standing workplaces.
O-361 ENHANCING OCCUPATIONAL HEALTH NURSING THROUGH PRACTICE. - CLOSE THE GAP IN CLINICAL SERVICES – A RESEARCH CONCEPT
Authors: Davies Kim 
Published: July 2024

Abstract

Introduction
A key goal in ensuring employee well-being and fostering a healthy workplace is closing the clinical services gap through improved occupational health nurse practice. The protection of employees’ health and safety, the prevention of illnesses and accidents related to the job, and the promotion of general employee wellness are all essential tasks carried out by occupational health nurses.

Methods
A qualitative design using ground theory methodology will be utilized to collect data using interviews with clinical practice nurses.

Results and Discussion
This grounded theory methodology will be used to identify key concepts with regard to closing the gap in the clinical practice of a private Occupational Health service. Occupational Health Nurse practitioners working in the industry will be selected to partake in the study. Participants will be asked to have first-hand knowledge of the phenomenon being studied and have been in the industry for at least 5 years. Focus group discussions and/or interviews will be used to gather data, which will then be verbatim recorded, transcribed, and subjected to thematic analysis.

Discussion and Conclusion
This flexible thematic analysis method will enable researchers to gain deep insights from qualitative data. It is appropriate for a variety of study environments because it doesn’t rely on any one theory. To guarantee that the final themes appropriately reflect the content and context, data must be handled carefully and methodically. Contribution By implementing these strategies, organizations can empower occupational health nurses to provide comprehensive clinical services, close the gap in healthcare delivery, and ultimately contribute to a healthier and safer workplace for all employees
