Authors: Mirabile Marco , Russo Simone , Fortuna Grazia , Vasselli Donatella , Valenti Antonio , Boccuni Valeria , Cannone Erika , Gagliardi Diana
Published: July 2024

Introduction

Technological innovation and knowledge development are key factors for the identification of traditional and emerging risks in OSH. We mapped the OSH research projects funded by European research programmes between 2014 and 2020 and we developed a network analysis in order to identify the products and assess the effectiveness of different networks working on the topic.

Methods

CORDIS, the European Commission’s primary public repository of information on all European Union funded research, was analyzed. We developed and tested search strings based on keywords suitable for the identification of projects whose general or specific objective was the advancement of knowledge, the development of functional tools and/or innovation aimed at strengthening OSH policies. Network analysis was performed to graphically describe and compute relevant indicators.

Results

58 OSH-relevant projects funded under the European R&D Framework Program Horizon 2020 and consistent with our inclusion criteria were identified in the CORDIS database. For each project, data relating to the thematic areas, the expected results/products (e.g. new knowledge, policy tools, technological innovation), the size of the funding assigned and the composition of the partnership were extracted. The application of network analysis allowed us to gain valuable insights into the structure and characteristics of the studied networks, providing a comprehensive understanding of the underlying relationships and facilitating the exploration of key patterns and trends.

Conclusions

This study allowed to collect and collate information about composition, functioning and effectiveness of European research networks aimed at improving workers’ health and safety through research, development, and innovation activities.
O-302 THE REGULATORY PERSPECTIVES TO THE PREVALENCE OF PSYCHOSOCIAL RISKS AFRICAN WORKPLACES
Authors: Iden Ehimare
Published: July 2024

Background

While employees’ health and wellbeing have become strong elements eliciting attention in global conversations, legal tools and framework are being designed and reviewed at International, Country and even enterprise levels.

Methods

Sadly, the African scenario has not evolved significantly yet psychosocial hazards grow daily with unquantifiable impacts on employees’ mental health and wellbeing. Arguably, this is no longer about employees only but about employees and employees’ families who are by extension impacted by the health and wellbeing conditions or outcomes of the principal employee.

Results

A notable hindrance to these improvements as expected is the state of outdatedness and in some instances unavailability of Occupational Health and Safety Legislative Framework and even when they exist, very little provision is seen covering employees’ mental health and wellbeing.

Discussion

What are perhaps the factors responsible for this absence of enabling laws and what definite impact is this having on employees mental health and wellbeing management?

Are there possible quick interventions? What could be the role of the government, employers, employees and employees’ family within this intervention and how will this impact positively on employees health and wellbeing outcomes?
O-304 THE RIGHT TO DISCONNECT: THE NEED TO ACHIEVE A BETTER WORK-LIFE BALANCE IN TELEWORK
Authors: Antunes Evelise , Santos Marta , Fischer Frida
Published: July 2024

Introduction

On the emerging telework policy agenda, among the reformulations and new policies, is the right to disconnect.

Materials and Methods

We aim to examine, supported by a Brazilian case report, the challenges of achieving a work-life balance in teleworking. A qualitative study entailing document analysis was conducted to survey, using electronic documents, the countries that have regulated the right to disconnect. A case study was also carried out in a Section of the Brazilian Federal Courts System. In-depth interviews of 20 workers in the Brazilian Federal Judiciary during the COVID-19 pandemic were conducted. All interviews were transcribed and thematic analysis was performed with the software MAXQDA Plus 2022. This study focused on the experiences of workers in the thematic category home-work balance.

Results

The results show that many individuals reported difficulty disconnecting due to task overload, understaffed teams and tight deadlines. Being at home, available with a computer and cell phone connected, yet not meeting the needs of other colleagues working at different times, appeared contradictory. Making oneself always available became the rule in teleworking, particularly for managers within the federal courts system. In this context, there was a need to guarantee the ability of people to disconnect from work and not to engage in work-related electronic communications during non-work hours, a right to disconnect policy.

Discussion/ conclusion

In Brazil, unlike other countries, the legislation governing telework fails to address the right to disconnect with the depth required. Nonetheless, other countries have made strides in teleworking regulations: Argentina, Belgium, Chile, Colombia, France, Ireland, Italy, Mexico, Peru, Philippines, Portugal and Spain.
O-305 BETTER CONSIDERING PSYCHOSOCIAL RISKS IN AGRICULTURE: PRESENTATION OF A FRENCH REPORT
Authors: Comptrasec Loic Lerouge
Published: July 2024

Introduction

Agriculture is poorly integrated into the analysis of working conditions. Even though the French agricultural social security system is innovative compared with other sectors because farmers are covered, it does not in itself result in equal coverage. E.g. when it comes to psychosocial risks (PSR), the issue of compensation is different for farmers and employees, and the question of suicides arises in this context.

Methods

PSR in agriculture exists and is a reality that still needs to be better understood. Better visibility and objectivization in the major surveys is needed, i.e. “making visible what is not visible.” Furthermore, under-reporting leads to a lack of recognition and compensation for victims and families. This issue concerns recognition of the impact of agricultural work on health, over and above the economic issues that are often put forward, such as economic difficulties and job insecurity. Another is not daring to talk about suicide or depression and going beyond information and awareness-raising.

Discussion

Improving the way PSR are addressed in agriculture also means providing the means to talk about it, particularly suicide and depression. Educational approach is a key and goes hand in hand with and facilitates better assessment, and improves prevention or compensation processes when prevention does not work.

Conclusion

The report makes recommendations to address these complex issues, divided into three parts: make working conditions of famers and employees more visible in surveys; improve the way in which the impact of PSR on health is considered as occupational accidents and diseases; and emphasize prevention of PSR for employees as well as farmers.
O-307 SYSTEMATIC REVIEW AND META-ANALYSIS OF PSYCHOSOCIAL INTERVENTIONS TO REDUCE CASES OF WORKPLACE VIOLENCE
Authors: Esquivel-Lozada Carlos , Juárez-García Arturo
Published: July 2024

Introduction

Interventions in Psychosocial Risk Factors are poorly studied in terms of reporting their efficacies that can be compared or replicated, among the most prevalent Psychosocial Risk Factors is Workplace Violence, documenting the size of the effect and comparing the interventions applied to The prevention of a psychosocial risk factor is essential to reach international agreements on the global, regional or local treatment suggested in the scientific literature.

Method

We searched the keywords “Workplace Violence” and “Clinical Trial” with the Boolean operator AND on PubMed Cochrane Clinical Trials.gov, Embase, PsycInfo, Web of science and Science Direct platforms. 95 results were obtained. The results were classified by type of violence (I, II, and III) and by Physical and Psychological. The effect size measures were compared with each other, transforming them all to OR through the formulas proposed by Fritz, Morris, and Richler.

Results

Will be obtained November 2023

Discussion

The main difficulty in making decisions to intervene on workplace violence is the lack of scientific evidence that establishes effect sizes, and once these effect sizes are established, they are expressed in different measures that can generate difficulty in their understanding or comparison for the reader, once this first problem is solved, comparing the three types of violence and two categories of violence results in small groups of type and category, however, it allows refining the conceptual accuracy

Conclusion

Published: July 2024

Introduction

Violence is an emerging social phenomenon which threatens our society, particularly health care personnel. The aim of the study was to identify the characteristics of violence perpetrated on trainee physicians and its physical and psychological impacts.

Methods

it was a descriptive cross-sectional study. Data were collected from a self-administered questionnaire. It was conducted in ten university hospitals in Tunis.

Results

of 257 surveys distributed, 207 (80,5%) were returned. It was a population with a mean age of 26.8 ± 2.35 years, sex ratio was 0.46 and 59.4% of them were internal physicians. During the previous twelve months, 98.1% of the respondents’ trainee physicians were victims and/or witnesses of violence. Indeed, 62.5% of the participants had been subjected to or had witnessed verbal abuse, 24.1% of them had been subjected to or had witnessed physical violence and only 13.3% had experienced or witnessed incivility during the previous year. The most frequent reason of violence was the long waiting time before consultation (62.5%, p=0.003). Nearly 93% of physical and non-physical violence had different psychological effects. A decline in the quality of job performance was reported by 96% of trainee physicians.

Discussion

Health care professionals are in direct contact with vulnerable people who endanger any normal social relationship. Trainee physicians were frequently exposed to violence. This phenomenon has serious personal and professional impacts.

Conclusion

There is a strong need for the development of preventive programs in order to manage violence in emergency departments mainly in focusing on security measurements’ strengthening.

It is crucial to ensure the engagement and investment of multiple stakeholders in the initiatives. These recommendations will contribute to further refining China’s OHS policy system for health workers.

Conclusion

China is the home to more than 11 million health workers; it is necessary to apply the WHO-ILO guidance under the priorities in China.
P-468 PSYCHOSOCIAL RISKS AMONG PHYSICIANS WORKING IN OCCUPATIONAL MEDICINE GROUPS IN TUNISIA
Authors: Maayouf Mouna , Kammoun Nesrine , Rmadi Nehla , Chemingui Siwar , Fehri Sonia , Hajjaji Mounira
Published: July 2024

Introduction

Work-related stress is a significant risk factor contributing to burnout, especially in professions characterized by elevated mental demands such as front-line occupational physicians. The aim of our study was to assess the extent of psychosocial risk (PSR) factors among occupational physicians.

Methods

A descriptive cross-sectional survey was conducted among physicians working in occupational medicine groups in Tunisia in November 2022. The Karasek questionnaire and Siegrist’s effort/reward imbalance model were utilized to assess PSR factors among the participants.

Results

The participation rate was 46%. The mean age was 41± 6 years. The sex ratio was 0.2. A high psychological demand and a low level of social support were found in 79% and 75% of the cases respectively. The prevalence of job strain was 60% and iso strain 75%. Effort/reward imbalance was noted in 30% of cases. High psychological demand and low social support were significantly associated with the number of patients per day and per year. Low decision latitude was significantly associated with the number of patients per year, the scarcity of participation in medical training and the presence of third-party constraints whose purpose is to interfere with the medical decision. The main source of work-related stress was poor administrative management for 38% of cases.

Discussion

These findings highlight the prevalence of PSR among occupational physicians. We recommend considering a legislative reform to improve the overall well-being of these healthcare professionals.

Conclusion

One out of two occupational physicians is experiencing job strain. A specific preventive strategy is suggested, as well as a legislative reform.
P-469 DEVELOPMENT OF THE CHINESE VERSION OF THE NEW BRIEF JOB STRESS QUESTIONNAIRE (NEW BJSQ) AND EXPLORATION OF THE ASSOCIATION BETWEEN NEW BJSQ AND FATIGUE
Authors: Lin Chia-Ping , Yang Chen-Cheng , Chuang Hung-Yi , Watanabe Kazuhiro , Kawakami Norito
Published: July 2024

Introduction

While fatigue is a common experience among workers, it can severely impact work performance, increasing the risk of accidents. Moreover, chronic fatigue is often an initial indicator and symptom of psychological stress. This study aimed to assess a broader range of psychosocial factors and explore the relationship between New BJSQ and fatigue.

Methods

We conducted a cross-sectional study involving labor workers from Occupational Health Services (OHS) and out-patients of Kaohsiung Municipal Siaogang Hospital. The self-administered questionnaire included the checklist Individual Strength (CIS) and New BJSQ.

Results

Among the 245 workers analyzed, 39.3% were recruited from hospitals, while 60.3% came from workplaces. Using a CIS score cut-off of 76 points, 27.8% exceeded this threshold. After adjusting for confounding variables, the logistic regression revealed that older age was associated with a lower risk of fatigue (OR=0.95, CI: 0.92-0.98), and higher job demand was linked to lower levels of fatigue (OR=0.54, CI: 0.35-0.84).

Discussion

This study sheds light on the relationship between psychosocial factors and labor worker fatigue. Notably, lower job demand was linked to higher fatigue levels, emphasizing the need to consider various psychosocial factors beyond job demand when studying fatigue.

Conclusion

Younger workers may face a higher risk of fatigue, with job demand significantly impacting fatigue levels. Strategies for improving labor workers’ well-being and performance should address these psychosocial factors accordingly.
O-315 MOVING FORWARD IN JOB RELATED SKIN CANCER - MEASUREMENT OF OCCUPATIONAL AND LEISURE TIME UV EXPOSURE
Authors: Strehl Claudine , Wittlich Marc
Published: July 2024

Introduction & Objectives

To address the constantly rising incidences of job related non-melanoma skin cancer many efforts will have to be made especially in primary prevention. By measuring UV exposure for a large number of outdoor workers supplemented by measurement of UV exposure during several leisure time activities typically performed outdoors we were able to build a large database which can serve as a starting point for further investigation of mechanisms leading to skin cancer as well as development of tailor made prevention concepts.

Materials & Methods

Occupational as well as leisure time UV exposure was measured via electronic data logger dosimeters for a wide range of occupational settings and leisure time activities. During measurements of occupational UV exposure more than 250 occupational settings could be investigated. Statistical surveys on the time use of the German population served as basis for identification of in total 14 typical leisure time activities that unite both: significant proportion at the entire course of the day and notable exposure to UV radiation.

Results

Measurements of occupational UV exposure revealed that next to the previously suspected industry sectors there also exist other occupations that formerly were not associated with high doses of UV exposure.

Discussion

In combination with measured values collected for leisure time activities, an average daily and annual exposure could be estimated.

Conclusion

Since 2014 a large database on occupational and leisure time UV exposure was built by real life measurements. Our data can serve as a database for different fields of application e.g. primary prevention or epidemiology of skin cancer.
O-319 KNOWLEDGE, ATTITUDES AND PRACTICES OF HOSPITAL RADIOLOGY STAFF WITH REGARD TO RADIATION PROTECTION
Authors: Saida El Kherrat , Nadia Manar , Hicham El Bouri , Frédéric Deschamps , Chakib Laraqui
Published: July 2024

Introduction

Radiation protection is based on the application of 3 principles: justification, optimization and dose limitation, which were established by the International Commission on radiological protection. This study aimed to assess the knowledge, attitudes and practices of hospital radiology staff regarding radiation protection.

Methods

This cross-sectional study, carried out in 2022 in 3 localities, involved 192 health care workers exposed to the risk of irradiation (156 radiology technicians, 32 radiologists and 4 service staff) with occupational seniority > 1 year and working full time. The self- administered questionnaire recommended by UNSCEAR included socio-demographic and occupational parameters and items relating to knowledge, attitudes and practices on radiation protection.

Results and discussion

The fundamentals of radiation protection were unknown by 29.2% and its objectives by 74% Only 24.5% were satisfied with the information on the risk of exposure. 57.8% reported that their radioprotection status was not up to date and 71.9% did not benefit from specific medical follow-up by the occupational physician. The design of the premises did not meet radiation protection standards for 39.6%. The radioprotection regulations mentioning the authorized dose limits were not displayed, as was the service plan specifying the traffic areas with the location of sources and the intervention plan in the event of accidental exposure to radios. Personal dosimetry was non-existent for 20.8%. 69,8% informed the patient of the risks of ionizing radiation when it seemed necessary to them.

Conclusion

Limited knowledge and faulty attitudes and practices towards radiation exposure require national supervision of radioprotection of health care workers. On-the-job training is necessary.
P-477 LESSONS AND LEARNED; THE CHANGING INDUSTRIAL HEALTH NEEDS AFTER THE NUCLEAR DISASTER AND IMPLICATIONS FOR FUTURE DISASTERS
Authors: Tateishi Seiichiro , Igarashi Yu , Mori Koji
Published: July 2024

Introduction

The Fukushima Daiichi Nuclear Power Plant (1F) accident posed significant challenges to industrial health management. The University of Occupational and Environmental Health, Jaan played a vital role in providing support during the aftermath. Understanding the dynamic changes in industrial health needs over time is crucial for effective disaster response and preparedness.

Method

The 1F Network Research Meetings, held regularly, facilitated discussions among industrial physicians, experts, and cooperating companies. Through a thorough review of meeting minutes, we categorized the industrial health needs and responses in different post-disaster stages.

Result

During the initial recovery phase, focus on restoring operations and managing radiation led to oversight of recovery workers’ health and safety. Challenges included inadequate heatstroke prevention during extended summer work, fatigue management from continuous shifts, and insufficient health protocols. After the decision to decommission the plant, the importance of long-term health management for workers became evident, resulting in precise health examinations. The increased risk of internal exposure to alpha nuclides necessitated discussions on screening and countermeasures. Ten years later, cases of cancer with uncertain radiation origins prompted discussions on corporate responsibilities.

Discussion

The findings highlight the diverse Occupational health needs after nuclear disasters and underscore the need for constant preparedness for future catastrophes. The establishment of external industrial health support teams by the Japanese Ministry of Health, Labor, and Welfare is a positive step. However, maintaining readiness and mechanisms for prompt response remain crucial in navigating crises effectively.

Conclusion

These insights can guide policymakers and stakeholders in enhancing industrial health strategies and disaster management practices.
P-483 DOSIMETRIC COMPARISON BETWEEN PHOTON AND PROTON IRRADIATION FOR PROSTATE CANCER: HIGHLIGHTING THERAPEUTIC EFFICACY AND RADIOPROTECTION
Authors: Ghazi Ismail , Krim Mustapha , Siroua Karima , Laraqui Chakib
Published: July 2024

Introduction

Prostate cancer is a common disease affecting the male reproductive gland. Our main goal is to create a realistic mathematical model of the male pelvic area. We aim to compare radiation doses from photons and protons to determine the most effective method, minimizing risks to the patient’s organs while maximizing protection for healthcare personnel. The radioprotection is based on three fundamental principles: justification, optimization and dose limitation.

Methods

We employed Monte Carlo methods, probabilistic algorithms for approximate numerical calculations. The simulations were performed using GEANT4, version 10.04.p03, an interface software that simulates particle movement through matter. GEANT4 succeeds the CERN- developed GEANT software series, utilizing C++ and an object-oriented programming methodology.

Results

Our findings highlighted the superior therapeutic efficacy of proton irradiation in depositing doses within the patient’s organs at risk. Additionally, proton treatment provided enhanced protection for healthcare personnel. Compared to photon irradiation, proton therapy proved more advantageous in terms of radioprotection.

Discussion

The underlying physics of these therapies differ significantly. Photons involve an indirect dose deposition, requiring two collision steps before interacting with a target electron and resulting in numerous scattered photons. In contrast, protons directly and continuously deposit energy, characterized by the Bragg peak.

Conclusion

The therapeutic effectiveness of proton irradiation in terms of radioprotection was emphasized. Nevertheless, implementing charged particle treatment demands extensive and costly experimental protocols. Therefore, photon irradiation remains one of the most widely used techniques for prostate cancer treatment, owing to its well-established advantages.
O-320 PHTHALATE EXPOSURE AND BIOMARKERS OF OXIDATION OF NUCLEIC ACIDS: RESULTS ON COUPLES ATTENDING A FERTILITY CENTER
Authors: Paci Enrico , Pigini Daniela , Caporossi Lidia , Capanna Silvia , Viganò Paola , Alteri Alessandra , Rabellotti Elisa , Buonaurio Flavia , Papaleo Bruno , Tranfo Giovanna
Published: July 2024

Introduction

Phthalates are substances used as plastics additives and solvents in various personal care products that act as endocrine disruptors. Among the mechanisms involved in the onset of these results is the induction of oxidative stress. The aim of the study is to show the possible relationship between urinary concentrations of phthalate metabolites and the biomarkers of nucleic acid oxidation, methylation, or protein nitroxidation.

Methods

Urine samples were analyzed for the phthalate metabolites Mono-ethylphtalate (MEP), Mono-benzylphtalate (MBzP), Mono-n-butylphtalate (MnBP), Mono-(2-ethylexyl)phtalate (MEHP), mono-(2-ethyl-5-hydroxyhexyl)phthalate (MEHHP), and Mono-n-octylphtalate (MnOP), and for the oxidative stress biomarkers 8-oxo-7,8-dihydroguanine (8-oxoGua), 8-oxo-7,8-dihydroguanosine (8-oxoGuo), 8-oxo-7,8-dihydro-2-deoxyguanosine (8-oxodGuo), 3-nitrotyrosine (3-NO2Tyr), and 5-methylcytidine (5-MeCyt). 274 couples attending a fertility center were enrolled, and urine samples were analyzed in HPLC/MS-MS; two sub-groups with urinary concentration > 90th or <10th percentile were identified, reducing the sample size to 112 subjects.

Results

A statistically significant difference for 8-oxoGuo and 3-NO2Tyr between men and women, with higher levels in men, was found. The levels of oxidative stress biomarkers were directly correlated with some phthalate concentrations in both sexes.

Discussion

The results of biological monitoring of phthalates exposure showed statistically significant correlations with the biomarkers of oxidative stress, 8 confirming that exposure to phthalates of various origins may induce oxidative stress, and, to some extent, it could suggest an involvement in the reproductive system problems.

Conclusion

As our results show DEHP as the most toxic phthalate, other phthalates are also involved, in different ways, in oxidative damage and, therefore, infertility.
O-321 A CASE/CONTROL STUDY ON FEMALE FERTILITY AND EXPOSURE TO REPROTOXIC PLASTIFICANT CHEMICALS
Authors: Caporossi Lidia , Capanna Silvia , Viganò Paola , Alteri Alessandra , Paci Enrico , Pigini Daniela , Tranfo Giovanna , Papaleo Bruno
Published: July 2024

Introduction

Infertility is a pathological condition with multifactorial etiology, investigating the role of exposure to reprotoxic chemicals is an urgent need for research in the field of health and safety at work. Phthalates and bisphenol A (BPA) are xenoestrogenic compounds with annual production in the order of thousands of tons and are present in many working environments.

Method

186 women attending an assisted fertilisation centre were recruited, age <43, body mass index, alcohol, smoking, age and specific pathologies were considered confounding factors. In addition, 196 women were recruited as controls, in the obstetrics department, with at least one child generated without any therapies and with a time to pregnancy < 12 months. A urine sample for each woman was analysed in HPLC/MS/MS for the presence of 6 metabolites of phthalates and BPA. The Institutional Review Board of the IRCCS San Raffaele, Scientific Institute in Milan, Italy, approved the research protocol(identification code 73/INT/2017).

Results

The case-control comparison showed statistically higher values in cases compared to controls for all analytes (p<0.05, Mann Whitney test) except for monooctylphthalate. Stratifying by infertility factors, in particular, it emerges how women with polyabortivity (820.5±1929.5) or “sine causa” infertility (230.5±794.2) had, on average, monoethyl phthalate (MEP) concentrations, in µg/g creatinine, significantly higher than all other infertility factors (76.2±145.6) and controls (101.1±292.2).

Discussion and conclusion

Having almost 10 times more MEP in women with polyabortivity and double in “sine causa” women suggests that exposure to this xenoestrogen can significantly affect reproductive health and require attention in the case of involved workplaces.
O-322 RISK OF ADVERSE PREGNANCY OUTCOMES AMONG PREGNANT WOMEN IN UNORGANIZED OR ORGANIZED WORKPLACES - WHO IS MORE SUSCEPTIBLE?
Authors: Venugopal Vidhya , Ramachandra Sri , Shanmugam Rekha , Ramachandra Sri , Elizabeth Jane
Published: July 2024

Introduction

Most affected by climate change-induced heat in developing countries are pregnant women who work in environments with limited access to heat mitigation strategies.

Methodology

In Tamilnadu, India, 230 expectant women from unorganized workplaces (UWs) and 384 from organized workplaces (OWs) participated in an observational prospective cohort study. In addition to the pre-and post-shift measurements of Core Body Temperature (CBT) and Urine Specific Gravity (USG), the Wet Bulb Globe Temperature (WBGT°C) was measured, and a validated questionnaire was used to collect self-reported heat-related symptoms. Postpartum interviews uncovered Adverse Pregnancy Outcomes (APOs). SPSS 16.0 modeled univariate and multivariate logistic regression.

Results

OWs’ WBGT°C values ranged from 24.1-28.5°C in OWs while in UWs’ it ranged from 24.1-30.2°C. Half of UW women exceeded the Threshold Limit Values (TLVs). Exposures to WBGT>27.5°C increased APO risk for women in UWs by 1.9-fold, and 44.3% of expectant UWs had chronic dehydration. The risk of spontaneous abortion/miscarriage was 2.3 times greater and adverse birth outcomes were doubled (95%CI: 1.1-5.2) among pregnant women working in UWs.

Discussion

Our study indicates that exposures to WBGT in excess of TLVs during all three trimesters of pregnancy, in conjunction with poor welfare and working conditions for women in UWs, could lead to fetal heat stress and an increased risk of APOs.

Conclusion

To safeguard pregnant women from the negative effects of occupational heat stress, it is necessary to implement protective labor policies and improve workplace welfare facilities.
O-325 PHYSICAL WORK DEMANDS DURING PREGNANCY AND THE RISK OF PRETERM BIRTH – FINDINGS FROM A DANISH REGISTER-BASED COHORT STUDY
Authors: Sejbaek Camilla Sandal , Flachs Esben Meulengracht , Frankel Hannah Nørtoft , Mehlum Ingrid Sivesind , Tøttenborg Sandra Søgaard , Madsen Ida E H , Rugulies Reiner , Hougaard Karin Sørig , Bonde Jens Peter , Begtrup Luise Moelenberg
Published: July 2024

Introduction

The objective of this study was to corroborate or refute earlier indications that high workload in pregnancy is associated with preterm birth.

Methods

The register-based cohort, DOC*X-Generation, included all working pregnant women and their liveborn children in Denmark (1977-2018). Register-data contributed information of gestational age used to define preterm (22-36 gestational week) and extremely preterm (22-32 gestational week) births, and occupational codes during pregnancy – DISCO-88. A Job exposure matrix (JEM) provided information on occupational exposure for each occupation and not individually. Workload was provided by the JEM, physical work demands (Work Environment and Health, Denmark), which assigned each woman with an exposure value based on DISCO-88 occupational codes. Other nationwide registers provided potential confounders.

Results

The preliminary findings included 1,201,974 women working during pregnancy; of which 4.3% gave birth preterm. Employment in occupations with high physical work demands during pregnancy was associated with a small increased risk of preterm birth (highest exposed group, adjusted OR=1.10 (95% CI 1.06-1.13)) and extremely preterm birth (highest exposed group, adjusted OR=1.15 (95% CI 1.07-1.23)). There was a tendency towards an exposure-response relationship for both outcomes.

Discussion

Strengths include a non-selected cohort of working women over a 40-year period, including potential confounders, e.g., maternal country of origin and education. One limitation is that the JEM is only based on data from 2012 and 2014, and therefore does not reflect potential changes in physical workload over time.

Conclusion

This study supports the previous findings of an increased risk of preterm birth due to physical workload during pregnancy.
O-328 ASSESSING LUNG CANCER RISKS AMONG VICTIMS IN ASBESTOS DAMAGE RELIEF SYSTEM IN KOREA: EXCESS LIFETIME CANCER RISK WITH EXPOSURE ASSESSMENT
Authors: Kim MyongHwan , Lee Seungho , Kang Dongmug , KJ Ju Young Kim , Kim Yoon-Ji , Kim Youngki , Lee Eun-Soo
Published: July 2024

Introduction

The compensation criteria for lung cancer in Asbestos Damage Relief Act (ADRA) in Korea mainly rely on the presence of radiologic findings of asbestosis or pleural plaque. Although exposure criteria with asbestos fiber concentration in lung tissue is supplementary, it has not been applied. Because only 30% of asbestos related lung cancer has asbestosis or pleural plaque, substantial lung cancers might not be compensated by ADRA. Exposure criteria for lung cancer need to be applied in ADRA.

Methods

Data of 1,784 lung cancer compensation applicants during 2011-2021 were analyzed. Comprehensive asbestos exposure assessment including occupational, environmental, and household/family exposures were evaluated. To evaluate lung cancer risk the Excess Lifetime Cancer Risk (ELCR) method was employed.

Results

The average age of applicants was 69.1 years, with a significant majority in their 60s (34.6%) and 70s (35.8%). There were 1,268 male (71.1%) and 516 female (28.9%) applicants. Reports of occupational, environmental and household/family exposure came from 512 (28.7%), 1,028 (57.6%) and 504 (28.3%) individuals, respectively. The overall approval rate was 58.1%, with 97.7% for applicants with radiologic evidence and 4.1% for applicants without such conditions. Notably, approval rates were higher for deceased (69.6%) versus living applicants (46.6%). ELCR computation is ongoing.

Discussion

Asbestos compensation should be extended to strong exposure cases even without radiologic evidence. Identifying high-risk cohorts with significant past exposures would improve early detection. Exposure assessment tools and ELCR calculation would promote epidemiological research.

Conclusion

Incorporating exposure assessment and ELCR into ADRA’s framework could augment the equity of compensation decisions.
O-331 PREVALENCE OF RESPIRATORY SYMPTOMS AND DISEASES AS WELL AS VENTILATORY DISORDERS AMONG ARTISANAL WELDERS
Authors: Rkiek Bilal , Manar Nadia , Bouri Hicham El , Deschamps Frédéric , Laraqui Chakib
Published: July 2024

Introduction

the aim of this study was to assess the prevalence of respiratory symptoms and diseases, as well as ventilation defects, among artisanal welders.

Methods

This cross-sectional study involved 211 welders in Kenitra (Morocco) with at least two years’ seniority. It included an analysis of working conditions, a questionnaire and spirometry. The questionnaire comprised four sections: socio-demographic and occupational characteristics, smoking habits, medical history and clinical respiratory symptoms. Chronic bronchitis was defined as chronic cough and chronic sputum production occurring for at least three months of the year and for at least two consecutive years, with no other cause identified. The diagnosis of COPD was made in the presence of an obstructive ventilatory defect based on a forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) ratio <70% after administration of a bronchodilator.

Results

The average age was 43.5 ± 9.8 years. The average seniority was 15.8 ± 9.2 years. 29.4% were current tobacco smokers, 22.7% former tobacco smokers and 48.3% non-smokers. 13.3% were cannabis smokers. The prevalence of tracheobronchial irritation symptoms was 19.2%: 14.2% for chronic cough, 9.5% for respiratory discomfort, 12.8% for chronic expectoration and 9% for chest wheezing. The prevalence of rhinitis was 19.4%, asthma 8.5%, chronic bronchitis 10% and chronic obstructive pulmonary disease 9% (10.1% in current smokers and former smokers versus 7.8% in no-smokers). 24.6% had defects in FEV1 and FVC. This prevalence reached 31.2% in current smokers and former smokers versus 17,6% in non-smokers.

Conclusion

These artisan welders should benefit from occupational medical cover to improve prevention.
P-489 PREVALENCE OF RESPIRATORY SYMPTOMS, DISEASES AND VENTILATORY DISORDERS AMONG DENTAL TECHNICIANS
Authors: Manar Nadia , Bouri Hicham El , Laraqui Omar , Deschamps Frédéric , Laraqui Hossini Chakib El Houssine
Published: July 2024

Objective

To assess the prevalence of respiratory symptoms, diseases and ventilatory disorders among dental technicians.

Methods

This cross-sectional study involved 372 people working in 75 laboratories in Casablanca, Fez, Meknes, Rabat and Tangiers, and with at least two years’ seniority. It included a questionnaire, spirometry and thoracic radiophotography. The questionnaire consisted of four sections: socio-demographic and occupational characteristics, smoking habits, medical history and clinical respiratory symptoms. Chronic bronchitis is defined as chronic cough and chronic sputum production occurring for at least three months per year and for at least two consecutive years without any other identified cause. The diagnosis of COPD was made in the presence of an obstructive ventilatory defect based on a ratio forced expiratory volume at the first second/ forced vital capacity (FEV1/ FVC) <70% after administration of a bronchodilator

Results

Average age was 31.8±8.4 years. The predominance was male (73%) and the average seniority was 9.7±6.3years. 32.9% were current smokers, 12.4% former smokers and 54.7% non-smokers. The prevalence of tracheobronchial irritation symptoms was 25.2% for chronic cough, 9.7% for respiratory discomfort, 7.2% for chronic sputum and 8.7% for chest wheezing. Rhinitis was 18%, asthma 8.2%, chronic bronchitis 7.1% and chronic obstructive pulmonary disease 6.7% (7.1% in current and former smokers versus 3.4% in non-smokers). 19% had deficits in the (FEV1) and the (FVC). This prevalence reached 32% in current and former smokers. The prevalence of radiological abnormalities was 13.2% (5.2% had small parenchymal opacities suggestive of pneumoconiosis).

Conclusion

Prevention and early detection must be a priority in this sector.

Background

Diving is a strenuous underwater activity in which environmental conditions affect the functions and structure of tissues especially the respiratory system. So pulmonary function tests of the divers can give us valuable information about the consequences of this activity.

Aim

To assess changes in respiratory function after 8 years of professional diving.

Methods

A retrospective cohort study was performed on divers who have consulted in the occupational medicine department of a Tunisian Hospital during periodical fitness to work visits from 2014 to 2021. Pulmonary function tests were performed with the same operating standards and using a MIR spirolab III spirometry. Each subject acted as his or her own control.

Results

Seventy five divers were included in this study. The mean age was 36.6 ± 8.7 years. Smoking was reported in 68% of cases. In our study, none of the participants had a respiratory history. Over the 8 years, a significant decrease in the forced expired volume in 1 second/functional vital capacity (FEV1/FVC) ratio (p =0.0005) was reported as well as a decrease in the forced expiratory flow (FEF) at 25% and 75% (p=0.0024). A decrease in functional vital capacity (FVC) was also reported (p=0.006). There was a significant decrease in FEV1, FVC, DEM.50, in the age group between 40 and 60 years old and in the smokers group. No significant difference was reported with professional seniority.

Conclusion

Several factors accompanying the diving activity are capable of initiating damage to the airways justifying the prosecution of studies.
P-492 MEDICAL EXPERTISE IN ASBESTOSIS-RELATED OCCUPATIONAL DISEASES: TWO CASES REPORT
Authors: Abouzahir Hind , Elhamamouchi Ikram , Belhouss Ahmed , Benyaich Hicham
Published: July 2024

Background

Asbestos is a flexible and fibrous silicate that is highly resistant to physical and chemical conditions. Because of these characteristics, it has long been used in a range of industries, including insulation, textiles, ships, car production, and construction. Despite the fact that its use is banned in Morocco, as it is in many other countries, considerable occupational exposures can occur during the repair of outdated industrial products and building demolition.

Cases Presentation

Here, we report two examples involving male patients in their 60s who had no prior medical history. They described how they had worked on equipment lined with or containing asbestos-based materials while performing mechanical maintenance, service, and fitting out tasks. Clinical symptoms and particular radiological symptoms led to the diagnosis of asbestosis. Mild to moderate respiratory insufficiency was discovered throughout the assessment. Asbestosis as an occupational disease and job had a direct causal relationship, and in both situations, the rate of permanent partial impairment after expert’s assessment was from 30% to 60%.

Conclusion

Asbestosis is one of the occupational diseases for which workers are entitled to compensation under the law. Reporting occupational illnesses is required. To be eligible for compensation, the patient must have a diagnosis of the disease, which is why experts can also give testimony about asbestos exposure and any asbestos-related diseases that might come from it.

O-333 PESTICIDE EXPOSURE IN FRUIT-GROWING RE-ENTRY WORKERS: COMPARING LEVELS AND DETERMINANTS ASSESSED UNDER USUAL CONDITIONS OF WORK (CANEPA STUDY) WITH THOSE PREDICTED BY REGISTRATION PROCESS (EFSA MODEL)

Published: July 2024

Introduction

Pesticide exposure increases the risk of chronic disease among farmers. Understanding exposure is necessary for epidemiological and regulatory purposes. Since 2014, worker exposure has been assessed in the registration process by EFSA, using the OPEX model. Data specific to fruit-growing workers is limited to five European studies conducted in the 1980s by pesticide companies, among others. We compared exposure predicted in the regulations with that measured in field studies.

Methods

In 2016-2017, dermal exposure to captan and dithianon was measured in French farmers during 121 days of re-entry (net folding and deployment, thinning) and harvest, using patches and cotton gloves. Exposure was calculated using several parameters (task, personal protective equipment (PPE), treatment schedules). Exposure was recalculated from dislodgeable foliar residues (RDF) measured 2 to 312 days after application in 20 observations. Relationships between measured and calculated exposures were studied by linear regression.

Results

Exposure depended on PPE worn and tasks performed (thinning, net folding > harvest, net deployment) due to differences in pesticide accumulation on plants over the season. Most exposures calculated using default settings were 100 times higher than measured exposure. The model underestimated exposure recalculated with measured DFR in all observations for dithianon and almost all for captan.

Discussion

In the regulatory process, re-entry exposure is only calculated when it occurs immediately after application. Exposure measured up to 300 days after application was never zero. When re-entry was not immediate after application, the model underestimated exposure.

Conclusion

This demonstrates the importance of using field studies in the registration process to ensure a truly conservative approach.

Introduction

In response to consumer market demands, vegetable producers must ensure the production of high-quality crops. To achieve this, these producers often resort to pesticide use. Such usage must adhere to specific norms. This study aims to assess knowledge, practices, and compliance related to pesticide use in protected vegetable cultivation.

Methods

This cross-sectional study was conducted in Sidi Bouzid governorate from July 2022 to February 2023. We assessed knowledge and practices related to pesticide use in protected vegetable cultivation using face to face questionnaire guided interviews. We also evaluated distribution practices among pesticide sellers using a second questionnaire.

Results

Among the surveyed farmers, 44% had only primary education. Only 40% of farmers exhibited satisfactory knowledge of pests, diseases, and their occurrence periods. A significant majority (83%) of farmers demonstrated awareness of the names of purchased pesticides. Of the surveyed farmers, 87% obtained pesticides from authorized vendors. However, only 37% of farmers properly stored empty pesticide containers and refrained from repurposing them. Moreover, a majority of farmers (63%) admitted to not using personal protective equipment. Among the surveyed sellers, 64% were under control and coordinated their buying and selling operations with the Regional Agricultural Development Commission.

Discussion

This study unveiled non-compliance with phytosanitary requirements concerning pesticide usage in sheltered vegetable cultivation, shedding light on the need for improvements to address the highlighted non-conformities.

Conclusion

The study underscores the need to address non-compliance with phytosanitary requirements in protected vegetable cultivation. Recommendations for improvements are necessary to ensure safe and environmentally sound pesticide practices in the industry.
