Authors: Popa Maria Valentina , Gurzu Irina Luciana , Duceac Letitia Doina
Published: July 2024

Introduction

The COVID-19 pandemic, with massive absenteeism from work due to sickness and quarantine, has put pressure on healthcare workers. Our study compared staff illness patterns in a pediatric emergency clinical university hospital during the pandemic with pre-pandemic years.

Methods

A retrospective analysis of temporary sickness incapacity was carried out using medical leaves data from 2017-2019 compared with 2020-2022.

Results

The sick leaves of 1217 employees were classified by disease groups. Between 2017 and 2022, the number of medical certificates showed an increasing trend. The highest number of employees on medical leave was in 2020 (24.2%). In 2021 and 2022, the number of sick leaves decreased, but the number of days/persons increased. 986 days of leave were recorded for SARS-CoV2 infection, with an average of 8.15 days/case.

Discussion

Prolonged sick leave was taken by healthcare workers with pre-existing conditions and early pandemic infections.. Those confirmed with COVID-19 were absent for a variable length of time depending on the course of the disease. Cases of respiratory illness increased in March 2020, paralleling the trajectory of the COVID-19 curve and decreased since 2021 due to mask use and vaccination. After returning to work, some workers required long-term follow-up in various specialties, resulting in days of temporary incapacity to work.

Conclusion

In times of health crisis, implementing measures to minimize sickness absenteeism among health workers is vital to maintain an effective health system and a work environment suitable for all workers.

Ethics approval

The study was approved by the Institutional Ethical Committee of Clinical Emergency Hospital for Children Iasi.

Authors: Madigan Dana , Friedman Lee , Faydenko Jocelyn , Forst Linda , Cambron Jerrilyn
Published: July 2024

Introduction

Massage therapy involves pervasive ergonomic hazards, and most massage therapists (MTs) report experiencing adverse musculoskeletal health issues. Various barriers and facilitators can impact the efficacy of safety programs.

Methods

Baseline surveys were completed by MTs throughout the US recruited through two continuing education courses (n=8,305) to determine demographic characteristics, self-care behaviors, and self-reported musculoskeletal signs and symptoms. A subset (n=209) participated in a longitudinal study to characterize individual and organizational barriers and facilitators that influence the implementation of self-care techniques designed to reduce musculoskeletal health issues.

Results

31.5% (n=2,615) reported that they always or often experienced musculoskeletal signs and symptoms due to work in the preceding month. An increased odds of this were associated with female massage therapists, hours per week giving massages, working in medical or spa/salon/franchise settings, and poorer health. In the same model, lower odds were observed with more minutes taken to warm up on days giving a massage. MTs who reported time as a barrier implemented 0.9 fewer self-care items despite wanting to make changes (p=0.003) and 1.4 fewer self-care items when management was identified as a barrier (p<0.001). Only 277 MTs (3.3%) stated they notified their employer about their musculoskeletal signs and symptoms.

Discussion

Massage therapists commonly experience musculoskeletal signs and symptoms due to their work. They report knowledge of and desire to implement behaviors to prevent injury but face individual and organizational barriers.

Conclusion

Our findings show that organizational factors play a critical role in workplace safety, which can be used to improve working conditions faced by MTs.
O-149 WORKPLACE VIOLENCE IN A SECONDARY HOSPITAL IN WUHAN, CHINA IN THE CONTEXT OF COVID-19 PANDEMIC: A MIXED METHODS STUDY
Authors: Wang Fuyuan , Zhang Min
Published: July 2024

Introduction

The occupational health of health workers (HWs) has attracted widespread attention during COVID-19. The aim of this study is to explore risk factors for workplace violence (WPV) toward HWs and to provide tailored measures for prevention and control in the health sector.

Methods

In 2022, a mixed methods study was conducted in one sample hospital in Wuhan city, the hardest hit area by COVID-19 in China, combining a cross-sectional study on the risk factors and status of burnout and work ability, and qualitative interviews for the views of WPV. This study was approved for ethical review by the Peking Union Medical College.

Results

Among 571 respondents, the incidence rate of physical violence and psychological violence was 3.33% and 31.35%, respectively. Being male (OR=4.80, P=0.010), immigrating from other cities (OR=4.40, P=0.013), shift work (OR=2.83, P=0.001) and direct patient contact (OR=7.29, P<0.001) were risk factors. The experience of psychological violence was associated with an increase of burnout (t=-4.02), and a decrease of work ability (t=4.77). The negative impacts of WPV incidents ranged from psychological, cognitive to work motivation. The causes of WPV incidents arose from individual factors, organizational factors, work environment, and social factors.

Discussion

WPV towards HWs is a global problem with country-specific features. This study suggests a specific picture for WPV prevention and control in the hospital. Further research is needed on psychological violence and mental health outcomes.

Conclusion

In the post-COVID era, tackling WPV in the health sector needs systemic measures, and should be integrated into the occupational safety and health management system.
O-152 THE DEVELOPMENT AND TESTING OF A HOLISTIC JOB – LIFE DEMANDS – RESOURCES MODEL TO MEASURE PSYCHOSOCIAL RISKS AND WELL-BEING OF THE SELF-EMPLOYED
Authors: Delvaux Ellen , Meeuwssen Marjan , Vandenbroeck Sofie
Published: July 2024

Introduction

Within the Belgian context, a lot is known about the well-being and the work-related psychosocial risks for employees. However, we know less about the work-related well-being and psychosocial risks of the self-employed. The aim of this study was to develop and validate a holistic job – life demands – resources model to measure risk factors and well-being outcomes specific to the self-employed.

Methods

We tested this model in a cross-sectional online study with 4358 self-employed participants. To test the relationship between different risk factors and well-being indicators, we used correlation and regression analyses. To examine socio-demographic differences (e.g., gender, age, sector) in both risk factors and well-being indicators, we used Chi-square tests. The analyses were performed in SPSS.

Results

As expected, we found significant positive relationships between job resources (e.g., recognition) and well-being indicators (e.g., passion for the job), and between job demands (e.g., financial insecurity) and ill-being indicators (e.g., rumination) and significant negative relationships between job resources and ill-being indicators and job demands and well-being indicators. Also as expected, we found several significant differences in job demands – resources and well- and ill-being indicators based on characteristics such as gender, age and sector.

Discussion

Further research may validate this model in other national contexts. Also, longitudinal studies may shed light on the causal relationship between risk factors and well-being.

Conclusion

We found evidence for a holistic job – life demands – resources model for the self-employed. The findings from our study may inform programs and campaigns to foster the well-being of the self-employed.

Published: July 2024

Introduction

Micro and small enterprises (MSEs) rarely implement occupational stress prevention interventions due to limited resources and low prioritisation of stress prevention. To address these barriers, a user-friendly web-based stress prevention platform “System P” (SP) was developed for MSEs use without external help. It combines a psychosocial risk assessment (PRA) and an individual online stress management training (SMT). The study evaluates the implementation of System P in MSEs.

Methods

Via different addressing channels, more than 5413 MSEs were invited to use SP. As indicators for a successful implementation process, e.g. adoption, reach and fidelity were analysed, using a mixed-methods pre-post design with outcome measurements at baseline (T1) and after 6 months (T2), as well as SP usage data.

Results

Adoption: Between 12.2021 and 09.2022, 40 MSEs registered in SP, of which 24 adopted SP, characterized by good psychosocial safety climate. Reach: Within these MSEs, 17 % of the employees used SP. Fidelity: 11 MSEs started the PRA, one set up a measure, and no MSE finished the process. The SMT was started by 25 users and completed by 8 users.

Discussion

Only a small part of the target group was reached. Moreover, the sample was already highly informed about and showed high engagement in occupational stress prevention actions. Although MSEs started with the analysis, measures to improve work design were not taken. This matches the scientific findings in other contexts.

Conclusion

MSEs need to be accompanied by professionals to understand, systematically address and implement the issue of occupational stress prevention in the enterprises’ day-to-day work.

Authors: Theppitak Chalermsiri , Haputsa Budsakorn , Khamsai Supharak , Boonthos Saranya , Sitthisophonkamjorn Pawita , Ngansanthia Jenita , Nakaphong Aticha
Published: July 2024

Introduction

Stone-trimming work involves inappropriate postures and repetitive motions for long periods which may increase the risk of musculoskeletal disorders. This research aims to assess ergonomic risks and improve work processes and workstations to reduce ergonomic risks for stone-trimming workers.

Methods

The participants were 20 stone trimming workers. They were assessed ergonomic risks by Rapid Upper Limb Assessment (RULA) or Rapid Entire Body Assessment (REBA). Ergonomic risk reduction was made by improving work procedures and workstations. Ergonomic risk results and job satisfaction level were compared for before – after improvement. The study was approved by the Human Research Ethics Committee, Suranaree University with project code EC-62-115.

Results

Before improvement, the very high risk from REBA assessment was the stone-breaking process (11 points) and the stone-cutting process (10.6 points). The highest risk process from RULA assessment was the stone cracking and tying stone slabs with ropes (7 points). After improvement, it was found that the risk level of each step was slightly reduced. But the level of job satisfaction increased in terms of work efficiency, working environment, safety, and work processes.

Discussion

After using the stone wrapping device, ergonomic risk is slightly reduced. The time of each bind has been reduced from 41 to 20 seconds, and the hand/wrist rotation has been reduced from 8 to 2 per bind. Subjects feel comfortable without pain in hands and fingers.

Conclusion

Using the stone wrapping device and improvement of working processes and workstations slightly reduced the risk of ergonomics and the level of job satisfaction and efficiency increases.

Authors: Desai Nikunjkumar
Published: July 2024

Introduction

Chemical and dust exposure poses significant health risks to workers, leading to respiratory issues, skin irritations, and chronic illnesses. To address these challenges, employees initiated Chemical and Dust Exposure Reduction (CDER) projects under a continuous workplace excellence initiative aimed at minimizing these threats.

Methodology

CDER projects implemented in 46 plants in identified plants, categorized into CMR, Dust, HTM, and other chemicals projects. Tailored reduction methods, including engineering controls and cutting-edge technologies, were deployed to address specific challenges. Real time monitoring enabled swift responses to potential risks. Interventions: Key interventions involved substituting hazardous chemicals with safer alternatives, fostering a secure work environment. Success in reduction methods was reinforced by comprehensive communication programs empowering employees to adopt safety practices effectively. Safety protocols were reinforced to ensure the safe and efficient application of these reduction methods. Regular equipment maintenance and calibration were implemented to sustain optimal performance.

Results

Out of the 5,870 working population in Refinery and petrochemicals plants, 329 (5.6%) were exposed and hence directly benefited from the projects. Benefits were seen in terms of Occupational health hazards related to CMR (78 individuals), dust (151 individuals), HTMs (27 individuals), and other chemicals (73 individuals). The projects led to cost savings of approximately 19,00,000/- INR and enhanced administrative efficiency through automation. Inherent safety measures were strengthened, providing superior worker protection.

Discussion and Conclusion

The CDER projects yielded benefits for both the environment and the workers. Emissions were significantly reduced, resulting in a safer and more ecofriendly work environment. Workers’ occupational health also improved significantly due to minimized hazardous exposures.

Authors: Kornilenko Liubov , Stanislavoviene Jelena
Published: July 2024

Introduction

One of the main indicators of safety and health at work status is the incidence of occupational diseases. The aim of the study was to investigate the trends in the incidence of occupational diseases in Lithuania during the period of 2009-2022.

Methods

Incidence rates were calculated using data from the Republic of Lithuania National Register of Occupational Diseases. The rates were age-standardized using the direct standardization method. The changes in the incidence rates throughout the study period were analyzed using segmented regression calculated with the JOINPOINT statistical software. We determined joinpoints in the dynamic lines of the incidence rates and calculated mean annual relative (percentage) change for each period.

Results

Incidence of occupational diseases declined during the study period: in 2009-2011 years was observed a rapid fall - annual relative (percentage) change of 32.1 %, then in 2011-2017 there was a slight change (-0.2 %) every year, during 2017-2022 the incidence of occupational disease decrease 15.5 % annually. In summary, during 2009-2022 annual relative (percentage) change was -11.8 % (CI (-14.3) – (-9.1)), p <0.001.

Discussion

The results of the study reflect the statistics on the reduction of occupational diseases shown by Eurostat. Specialists in Lithuania see a number of reasons that determine such trends: improving working conditions, a small number of occupational medicine doctors, and other social circumstances.

Conclusion

During the study period, the incidence of occupational diseases decreased almost 5 times. The incidence was found to slightly decrease during the period of 2011-2017, very rapidly during 2009-2011, and from 2017 to 2022.

O-174 FACTORS ASSOCIATED WITH PRESENTEEISM AMONG PHYSICIANS WORKING IN OCCUPATIONAL HEALTH SERVICES IN BRAZIL
Authors: Silva-Junior Joao Silvestre , Helaehil Camila , da Cunha Arthur Arantes , Ogata Alberto José Niituma , Scarpellini Bruno , Demarch Rodrigo B , Marina Frida
Published: July 2024

Introduction

Presenteeism is defined as working while being ill, and it is a widespread global phenomenon among workers. In Brazil, labor legislation mandates companies to hire physicians for the development and implementation of health programs for their employees. This study aims to analyze factors associated with presenteeism among physicians working in occupational health services.

Methods

This cross-sectional study analyzed data from the third stage of a nationwide longitudinal research project. Data were collected in 2021, with 260 physicians responding to the Stanford Presenteeism Scale (SPS-6) and questionnaires regarding professional fulfillment, effort-reward imbalance, sociodemographic, and occupational aspects. A multiple binary logistic regression model was constructed to study the variables associated with presenteeism.

Results

The prevalence of presenteeism was 25%. Individuals with low professional fulfillment (OR 2.10; CI 95% 1.12-3.97), high overcommitment (OR 2.68; CI 95% 1.21-5.94), practicing occupational medicine for less than 20 years (OR 2.92; CI 95% 1.32-6.49), and working less than 40 hours per week (OR 1.89; CI 95% 1.02-3.54) had higher odds of presenteeism. Meanwhile, individuals with single marital status (OR 0.44; CI 95% 0.20-0.95) demonstrated lower odds. The model was adjusted by age and gender.

Discussion and Conclusion

Presenteeism in the studied population is lower than the data found in the literature. Numerous occupational aspects of physicians’ work were associated factors. Therefore, it is essential to implement health management strategies for them, as they are responsible for delivering comprehensive care to other employees.Acknowledgments: CGP Brasil for research funding; CNPq to FMFischer, grant 306963/2021-3.

Introduction

Primary care providers (PCPs) have scarce access to specialists in occupational and environmental medicine (OEM) regarding return to work, occupational injuries, illnesses, and environmental exposures. We conducted a pilot project to develop, implement and evaluate a teaching program on OEM for PCPs. The program also sought to improve communication between PCPs and the Ontario Workplace Safety and Insurance Board (WSIB) who provide wage-loss benefits and support for return to work after a work-related injury or illness.

Methods

We used the ECHO model to connect PCPs with OEM experts, using weekly video conference sessions to discuss participants’ cases and deliver didactic presentations. We invited PCPs to attend two cycles of 12 ECHO OEM sessions. An observational pre-post study design assessed changes in ECHO participants. Data were collected using online questionnaires for demographics, satisfaction, self-efficacy, knowledge, attitudes and beliefs. We analyzed the data using parametric and non-parametric statistics. Two cycles of 12 sessions each ran from September 2021 - June 2022, attended by various PCPs.

Results

229 participants registered, and 150 attended at least one session, of these 67 completed both pre- and post-ECHO questionnaires. ECHO OEM had a positive impact on satisfaction; self-efficacy increased post-ECHO (p<.0001) and knowledge increased after ECHO (p=0.004). Two of 10 items regarding attitudes and beliefs, related to perceptions, and the role of the WSIB significantly improved after ECHO (p<0.05). ECHO OEM was feasible and acceptable in Ontario.

Discussion and Conclusion

We demonstrated high satisfaction with the program, improved self-efficacy, increased knowledge, and improved attitudes and beliefs about the WSIB.
O-182 INVENTION AND VALIDATION OF REFERRAL CRITERIA FOR OCCUPATIONAL MUSCULOSKELETAL DISEASES
Authors: Joyce Li Lok Yee , Chen Ping Hui
Published: July 2024

Introduction

Diagnosis of occupational diseases(ODs) rely on both clinical physicians and occupational physicians to make clinical diagnoses and evaluate work-relatedness, respectively. Thus, referral mechanism is important for diagnosing ODs. Novel ODs, like musculoskeletal diseases (MSDs), have multiple etiologies, which makes ICD codes bad referral criteria with low positive predictive values. Our aim is inventing and validating criteria additional to ICD codes to enhance positive predictive values.

Methods

In Taiwan, Network of Occupational Diseases and Injuries Service is an important surveillance system of ODs. In NODIS, MSDs are most reported cases. Using the reporting data from 2012 to 2018, we use binomial regression model to investigate effect of these factors on work-relatedness, and subgroup analysis is carried out for each MSDs diagnosis. We then conduct a prospective study to validate effect of these predictors.

Results

In binomial regression model, longer tenure, ever taking leaves due to MSDs, construction industries, craft and related trades workers, technicians and associate professionals, elementary labourers, and main MSDs in OD list are significant predictors of work-relatedness. In subgroup analysis, predictors of work-relatedness vary between different MSDs. Preliminary data of prospective study validate our findings, but more data are needed.

Discussion

Each MSD has its unique predictor of work-relatedness, and we can identify high-risk characteristics, like age, gender, tenure, job title, industry, sick leave status, employment status, for each MSD.

Conclusion

Using each predictor’s coefficient, we can generate a set of referral criteria to refer cases with odds ratio of 2 or above, which enables better referral mechanism, which is more precise and more efficient.

Authors: Idrissi Kaitouni Mohammed Omar , Manar Nadia , Laraqui Omar , Deschamps Frédéric , Laraqui Hossini Chakib El Houssine
Published: July 2024

Introduction: Objective

critical analysis of medico-social cover for fishermen: limitations and recommendations. Medical and social cover for fishermen raises a number of issues of a legislative, ethical, deontological and practical nature.

Methods

A cross-sectional epidemiological survey was carried out among physicians working in the seafarers’ health facilities (ASGM).

Results and discussion

ASGM physicians, providing both care and prevention activities, infringe the provisions of the law relating to the practice of medicine. We have 20 occupational health physicians for 120,509 fishermen. We need around 70. The Ministry of Health provides the medical staff, which is an aberration because it pays the occupational health physicians who provide preventive care in the private sector. The Labor Code stipulates that medical services and the remuneration of occupational physicians are the responsibility of the company. Wouldn’t it be useful to introduce a compulsory prevention contribution, which would enable occupational health cover to be extended to the entire working population? Should the compulsory maritime insurance required of all shipowners include a contribution to occupational risk prevention? The high turnover of fishermen who change port of registration disrupts the proper monitoring of ASGMs. Wouldn’t it be useful to digitize the medical records and individual maritime booklet of fishermen as part of an intranet? The national reference rate has not been increased since 2006, resulting in quantitative and qualitative shortfalls in care. Shouldn’t a third-party payment system be considered?

Conclusion

Several actions are needed to improve the health and safety of fishermen
P-305 EXTREMELY LOW FREQUENCY ELECTRO- MAGNETIC FIELDS AND QUALITY OF SLEEP: A CROSS-SECTIONAL STUDY IN A POWER PLANT IN TUNISIA
Authors: Sridi Chayma , Kacem Imene , Jammeli Imene , Aloui Asma , Chelly Farah , Ksibi Sonia , Maoua Maher , Mrizak Najib
Published: July 2024

Introduction

Extremely Low Frequency Electro-Magnetic Fields (ELF-EMF) are widespread in our daily life and in the workplace. The aim of this study was to assess the impact of chronic occupational exposure to ELF-EMF on sleep quality among workers in the Tunisian Electricity and Gas Company.

Methods

In this cross-sectional study, the population was composed of two groups: an ‘exposed group’ represented by workers in a power plant and an ‘unexposed group’ represented by administrative workers belonging to the same company. The Exposure to ELF-EMF was assessed by spot measurements using a portable magnetometer. Sleep quality was assessed by the Pittsburgh Sleep Quality Index Questionnaire (PSQI).

Results

This study included 77 exposed subjects and 88 unexposed subjects. The median age was 37 years in the exposed group and 43.5 years in the unexposed group. Almost half of the exposed group were technicians. The median value of EMF was 5.9 µT in the power plant [Min=0,1;Max=40.3]. The interpretation of PSQI score showed that 64.9% of the exposed group had a bad quality of sleep versus 29.5% of the unexposed group (p<10-3). After multivariate analysis, ELF-EMF exposure was significantly associated with poor sleep quality (p<10-3;OR=1.28;95%CI=[1.14-1.43]).

Discussion

Chronic occupational exposure to ELF-EMF may have an impact on the quality of sleep. This impact could be explained by the disruption of circadian rhythms and the effects of ELF-EMF on the central nervous system.

Conclusion

It is essential to raise workers’ awareness of these risks in order to minimize the adverse effects on the quality of life of the workers concerned.
P-307 PICKWICK SYNDROME AND OCCUPATIONAL HAZARDS IN HIGH-RISK ACTIVITIES
Authors: Rincón Sarmiento Juan Ignacio
Published: July 2024

Introduction

Sleep disorders are increasingly prevalent in contemporary society. Many of these disorders are related to increased body weight. Obesity Hypoventilation Syndrome, also known as Pickwick syndrome, is a respiratory disorder that affects some people with obesity and can also have an impact on their work performance

Methods

A literature search was carried out using the words: obesity, Obesity Hypoventilation Syndrome, Pickwick syndrome, obesity, work accidents; showing that in effect this series of conditions derived from poor sleep quality increase the risk of presenting comorbidities, as well as presenting incidents at work. The foregoing with a view to strengthening this management at the National University of Colombia, in Bogotá.

Results

From this analysis, it was possible to conclude that workers diagnosed with obesity frequently have sleep disorders, which decreases their alertness even for work activities. This represents a huge risk whenever they face high-risk activities such as driving, working at heights, working in confined spaces, exposure to chemicals, etc.

Discussion

Rigorous control of variables such as body weight is required, especially in workers with high-risk activities. We should be concerned about the workers and their habits both inside and outside the companies and in this way try to influence their culture and health habits.

Conclusions

From the point of view of occupational risk management, it is essential to implement wellness programs and healthy habits in companies, as well as to continue working on public policies that prevent the development of obesity and metabolic disorders from an early age.

Introduction

In the motivational process of the Job Demands-Resources (JD-R) model, job resources are related to health and organizational outcomes through work engagement (WE). In the JD-R model, supervisor support can be considered as a job resource and employee turnover as an outcome. The purpose of this study is to examine the relationship between supervisor support and employee turnover.

Methods

A prospective cohort study was conducted in March 2022 and a follow-up survey was conducted in March 2023. The analysis was based on those who responded to both surveys. The explanatory variable was supervisor support at baseline, and the outcome was voluntary turnover between baseline and follow-up. Odds ratios and 95% CIs were calculated by logistic regression analysis adjusted for covariates (Model1:sex, age, marital status, child status, industry, working time system, job title, education, annual income, Model2:Model1+WE). This study was approved by the Ethics Committee of UOEH.

Results

A significant negative relationship was found between supervisor support at baseline and employee turnover between baseline and follow-up. Model1 was OR=0.944(95%CI;0.928-0.961, p<0.001) and Model2 was OR=0.939 (95%CI;0.922-0.957, p<0.001).

Discussion

Supervisor support was significantly negatively correlated with turnover. WE was significantly positively correlated with turnover, but it did not affect the effect of supervisor support to turnover.

Conclusion

This finding suggests that supervisor support may affect turnover through channels other than the motivational process, rather than through WE. Supervisor support may lead to turnover through channels other than the motivational process.

Published: July 2024

Introduction

Occupational eye trauma is a major source of workday injuries, with higher incidence in industrialized countries and accounting for 3% of emergency consultations. They are a major cause of vision loss worldwide, with a great socioeconomic impact.

Methods and Results

Ocular traumatisms occupy a relevant place in reported work accidents, their incidence is 1 per 10 thousand individuals, with a higher frequency in agricultural activities, metallurgical, electrical and construction industries, and health professions such as dentistry. In spite of the trend of occupational accidents in Colombia in recent years, it is possible that there is an underreporting of ocular trauma due to occupational accidents in ophthalmologic care. The purpose of this proposal is to characterize ocular trauma from emergency care in a high complexity clinic and the records classified as occupational accidents by occupational risk insurance companies.

Discussion and Conclusion

The analysis of the information will contribute to the knowledge on occupational ocular trauma in the southwestern region of the country and will make visible the need and importance of strengthening health prevention plans and programs, as well as the follow-up of labor inclusion in these specific situations.

Published: July 2024

Introduction

In Tunisia, brucellosis is endemic in certain regions, especially in rural areas. It is an occupational disease, primarily affecting professionals in contact with infected animals and laboratory workers. The aim of this study was to describe the circumstances surrounding work- related accidents occurring in laboratory workers due to inhalation of Brucella.

Methods

A retrospective descriptive study involving three laboratory workers who consulted the occupational department in February 2023 to report work-related accidents following accidental inhalation of Brucella. Data collection was done from medical records. A visit to the microbiology laboratory was conducted.

Results

The study included two women and one man, aged 28, 37, and 42 years. They worked as physician, laboratory technician, and nurse. All three laboratory workers had handled positive blood culture for Brucella. Two laboratory workers remained asymptomatic, while one developed a sudorificalgic fever. The workplace investigation revealed the absence of hoods and respiratory masks. The patients were referred to the infectious diseases department, where chemoprophylaxis with Rifampicin and Doxycycline was prescribed for three weeks for the first patient. For all patients, serological tests (Wright and Rose Bengal serologies) were conducted after two weeks to one month, and the results were negative. The work-related accidents were reported.

Discussion

This study highlights the work-related accidents in laboratory workers due to the inhalation of Brucella and the importance of protective equipment in bacteriology laboratories. Post- exposure prophylaxis is discussed.

Conclusion

The development of clinical practice guidelines for employees exposed to Brucella is an essential tool for occupational health physicians.
O-189 IMPLEMENTATION OF EXPOSURE-RISK RELATIONSHIPS AS BASIS FOR DIFFERENTIATED PROTECTIVE MEASURES
Authors: Pallapies Dirk , Welge Peter , Bruening Thomas
Published: July 2024

Introduction

In Germany, exposure-risk relationships for about 30 carcinogenic substances without effect threshold for carcinogenicity have been derived during the last decade. A tolerable concentration and an acceptable concentration associated with risk levels of 4:1,000 and 4:10,000 (target 4:100.000; additional lifetime cancer risk after exposure throughout the whole working life) define three workplace concentration ranges (“red”, “yellow”, “green” area, corresponding to high (not tolerable), medium (transiently tolerable), low (acceptable) risk, respectively).

Methods

Working groups of stakeholders in occupational safety and health developed a refined guidance for the derivation of the exposure-response relationships. Additionally, differentiated measures of the occupational health hygiene strategy will be characterized more in detail, depending on the risk levels that determine which protective measures will have to be applied in order to reduce the cancer risk for the workers.

Results

The refined guidance explains in detail how to select and assess both the relevant human and animal data, how to combine human and animal data and how to calculate the concentrations associated with the risk levels mentioned above. Examples of carcinogenic substances for which exposure-risk relationships exist are asbestos, benzene, ethylene oxide or metals such as cadmium, cobalt, nickel.

Discussion and Conclusion

This risk-based concept has been proven practicable and effective. While a similar concept does exist already in the Netherlands, it has now also been introduced to the European Union. A harmonized approach with an agreement about tolerable and/ or acceptable risks would enable an adequate protection of workers against carcinogenic risks on an EU-wide level.

Introduction

Pesticides are commonly used chemicals to improve agricultural yield and face farming challenges. However, these compounds might significantly affect the human health. In Morocco, pesticides are increasingly used in agriculture and start to constitute a major concern for farmers’ and farmworkers’ health, especially in rural areas where safety guidelines are weakly respected. Therefore, we aim in this study to assess the exposure of farmers and farmworkers to pesticides and evaluate the impact on their endocrine and epigenetic profiles.

Methods

This ongoiong study takes place in Meknes prefecture and is conceived based on an analytical cross-sectional design, consisting in exposed and control groups. 200 healthy and volunteer participants are asked to enroll the study following a clear informed consent, to answer a questionnaire on pesticide usage, exposure and lifestyle and to provide blood and urine samples. First, a set of 7 organophosphate pesticide metabolites will be quantified in urine using solid phase extraction and liquid chromatography methods being developed. Then, blood will serve in measuring thyroid and reproductive hormones in serum, in addition to global DNA methylation markers and specific hormones receptros genes in the whole blood.

Results

The results are expected to explain the association that might exist between pesticide exposure and epigenetic and/or endocrine alterations from one hand and the importance of Biomonitoring in preserving the health of Moroccan populations in occupational settings.

Discussion and conclusion

Finally, this study will help to shed light on the potential health risks in farmworkers related to pesticide usage and will promote knwoledge and safety elaboration to protect this range of population.
