O-332 ASSESSMENT OF CHEST X RAY PROFILE IN RELATION TO PREVALENCE OF SILICOSIS AMONG TUBERCULOSIS PATIENTS IN WEST JAVA, INDONESIA
Authors: Indriyati Leli Hesti
Published: July 2024

Introduction

Indonesia ranks third in the world for tuberculosis (TB), after India and China. The young and productive age group of 15-44 years is expected to have the highest burden of TB. This group is also the workers who are exposed to many hazards in their workplace including silica. The current study was aimed to analyze the chest X-ray profile in relation to the prevalence of silicosis among TB patients in Indonesia.

Methods

A hospital-based study in West Java among 312 TB patients was conducted from February to April 2022. Chest x-rays were evaluated by two radiologists and one NIOSH B reader according to the ILO Classification for the detection of pneumoconiosis.

Results

Most of the subjects were males (68.6%) with mean age 41.8±11.7 years. Radiographs consistent with silicosis were seen in 75 (24.0%) of patients, with about 77.3% being ILO categories 1 & 2; predominant by q shape;22.7% have large opacities and dominated by B shape. Pleural thickening was seen most prominently at the apex zone. Of all reported occupations with possible silica exposure, most of the subjects engaged in construction work (44.8%).

Discussion

Patients with silicotuberculosis were found to be underweight, have longer exposure to silica, and smoke more cigarettes per year.

Conclusion

This study indicates that TB patients who are the workers likely exposed to silica are at a high risk of developing silicosis. As a result, they should have active case detection and annual chest radiography.

Introduction

Work-aggravated asthma (WAA) represents a significant proportion of asthma in the workplace. This entity is distinguished from work-related asthma (WRA) by a particular allergic background and a different sectoral distribution.The aim of our study was to compare the socio-professional, clinical and etiological characteristics of two groups including WRA and WAA.

Methods

Retrospective descriptive study of patients who consulted the occupational pathology and fitness for work department of the Charles Nicolle Hospital during the period from January 2016 to December 2022.Two groups were defined G1: WRA G2: WAA.

Results

We identified 140 cases of asthma patients of whom 59% were WAA and 41% WRA. The sex ratio (M/F) was (G1=0.62, G2=1.51, p=0.012). The mean age was (G1=44±8 years, G2=42±9 years, p=0.18). Personal atopy was found (G1=44%, G2=70%, p=0.002). WRA was present in the textile sector (G1=33%, G2=10%, p=10-3), chemical industry (G1=23%, G2=23%, p=0.15). WAA was present in the transport (16%) and service (14%) sectors. An association of occupational asthma with occupational rhinitis was found (p=0.06). The average professional seniority was higher in WRA without significance (G1= 17±9 years, G2= 14±10years, p=0.11). The main agents incriminated in G1 were textile and vegetal dusts (25%) and isocyanates (16%).The avoidance of exposure to allergenic agents was indicated (G1 = 79% vs G2 = 85%;p=10-3).

Conclusion

According to our study, WRA is more frequent in women and in the textile sector and can be associated with occupational rhinitis.It is essential to keep away people at risk.
P-500 MACHINE LEARNING ALGORITHMS IN THE CLINICAL EVALUATION OF THE OBSTRUCTIVE SLEEP APNEA SYNDROME
Authors: Martini Agnese , Pietrafesa Emma , Polimeni Antonella , Luzzi Valeria , Russo Simone
Published: July 2024

Introduction

Obstructive sleep apnoea syndrome (OSAS) is an increasingly common disorder characterized by episodes of a complete or partial collapse of the upper airway during sleep, leading to oxygen desaturation and disrupted sleep. OSAS is related to increased risk of cardiovascular and cardiometabolic diseases, as well as increased morbidity and mortality (i.e. increase of road accidents and work injuries). Due to the growing number of subjects with suspected OSAS, the need for simple and effective diagnostic methods becomes urgent. The aim of the study was to apply the new machine learning algorithms (MLA) in the clinical evaluation of OSAS.

Methods

429 patients with suspected OSAS underwent anamnesis, nocturnal cardio-respiratory monitoring and a medical examination. The severity of OSAS was assessed through the Apnea Hypopnea Index (AHI). To verify the relationships between AHI, comorbidities, anthropometric and socio-demographic characteristics, we performed a multivariate analysis using MLA (logistic regression, Classification Tree and Random Forest).

Results

The study shows that certain clinical phenotypes (overweight or obese subjects) are more frequently associated with OSAS and that this association is even more significant in male subjects.

Discussion

Our study confirmed that sleep deprivation due to OSAS is closely linked to obesity and modification of the anthropometric characteristics that must be evaluated in the case of patients/workers with suspected OSAS. Indeed poor sleep increases hunger hormones. It may be due to higher sympathetic nerve activity, the stress response, caused by poor sleep.

Conclusion

Further studies will be needed to understand the use of MLA in diagnostic, prognostic and therapeutic decision-making of OSAS.
O-335 BILATERAL PTERYGIUM AS AN OCCUPATIONAL DISEASE IN FORESTRY WORKERS IN WASIOR, WEST PAPUA, INDONESIA: CASE REPORT
Authors: Danukusumo Lelitasari , Cahyono Agung
Published: July 2024

Introduction

Pterygium is an epithelial conjunctiva bulbi and connective tissue growth that could cause vision problems. Pterygium is mainly found in tropical and subtropical areas. Forestry workers almost all day work under the UV radiation exposure to the worker’s eyes. Wasior, West Papua is a coastal region where the sun shines all day.

Methods

A 53-year-old man, works as a wood volume measuring officer (skaller) for 5 years. This worker does their work for 7-8 hours every day in an open space under the sun on the beach. Previously the worker worked for 5 years in a fish processing company as the person in charge of the transportation fleet, the work was carried out in an open space by the beach and exposed to sunlight. During work the patient wears a hat but never uses anti-ultra violet glasses. Since 3 years ago, the patient has complained of red, itchy eyes and growing membranes in the corners of the left and right eye that move midway through the eyeball.

Results

The results of eye examination using a flashlight aid pterygium in the right eye grow from the corner of the inner eye and the outer corner of the eye has reached the middle of the cornea.

Discussion

Pterygium in the left eye grows from the corner of the inner eye already reaching the edge of the cornea.

Conclusion

Bilateral pterygium in these forestry workers meets the criteria to be categorized as occupational diseases based on work history and a history of ultraviolet exposure sufficient to cause pterygium in both eyes.

Authors: Hinson Antoine Vikkey , Yedjnou Azanmanvo Marcos , Djouaka Rousseau , Mikponhque Rose , Adjobimey Mènonli
Published: July 2024

Introduction

Contaminated food consumption is the cause of more than 200 diseases, ranging from diarrheal diseases, which kill the most, to cancer. In agriculture, the misuse of pesticides creates residues that pollute foods including milk and dairy products.

Aim

To assess the level of contamination in residues of 6 synthetic insecticides in fresh milk, and its by-products.

Method

This cross-sectional study included 45 samples of cow’s milk, curd and cheese. The samples per producer and per commune of fresh milk (6 samples of 500ml), curd (6 samples of 500ml) and cheese (3 samples of 500g) were collected aseptically. Quantitation of insecticide residues was performed by High performance liquid chromatography (HPLC) after QuEChERS extraction of the residues. The results of the analysis were compared with the Maximum residue limit (MRL) of the Codex Alimentarius and the European Union and compared according to matrices and localities.

Results

Insecticides’ main active ingredients authorized in Benin are acetamiprid (19%), cypermethrin (9%), lambdacyalothrin (8%), chlorpyrifos (9%) and profenofos (7%). All samples analyzed were free of chlorpyrifos, profenofos, lambdacyalothrin and DDT. Cypermethrin was quantified in all samples at levels ranging from 0.3 to 1.0 mg/ kg, all of which are above the MRL (0.05 mg/ kg). Acetamiprid was quantified in 41 samples out of 45 at levels ranging from 0.3 to 1.4 mg/ kg that are above the MRL (0.2 mg/ kg).

Conclusion

This study revealed a contamination of milk and its derivatives in residues of acetamiprid and cypermethrin: a health risk related to the consumption.

Authors: Lamouroux Céline , le Paul Adè , Lefevre Marie , Spinosi Johan , Guth Margot , Coste Astrid , Pérol Olivia , Fervers Béatrice , Charbotel Barbara
Published: July 2024

Introduction

With an incidence of 2769 cases in 2018 in France, testicular cancer is a “rare” cancer, however an increase in the incidence of TGT has been observed in recent decades. Recently, the link with pesticide exposure has begun to be suspected, but the data are currently discordant. The aim of the TESTISPRO study is to estimate the effects of individual occupational exposure to pesticides on the risk of developing a testicular tumor in adulthood, in young men of childbearing age.

Methods

The TESTISPRO study is a multicenter case-control study based in 20 French university hospitals between January 2015 and April 2018. 1124 participants (454 cases; 670 controls) were included and interviewed in the study. They were given a standardized questionnaire assessing their occupational exposure to pesticides. The results were analyzed by evaluators to define a level of pesticide exposure per individual according to a predefined standardized scale.

Results

Exposure to low levels of pesticides is associated with an OR of 1.15 [IC95% 0.64-2.04], while exposure to high levels of pesticides is significantly associated with a crude OR of 1.65 [IC95% 1.03-2.66]. The trend test is significant (p=0.02).

Discussion

These results suggest a positive association between occupational exposure to pesticides and the risk of TGT, also supported by a significant dose-effect.

Conclusion

This is the first study to show an association between testicular germ cell tumors and occupational exposure to pesticides. These results need to be confirmed by additional studies, particularly to elucidate potential pathophysiological mechanisms.
P-511 DEVELOPMENT OF A COMPREHENSIVE AGRICULTURE INJURY AND ILLNESS SYSTEM IN ILLINOIS, USA
Authors: Madigan Dana , Friedman Lee , Faydenko Jocelyn , Forst Linda
Published: July 2024

Introduction

Agriculture is a high-risk sector of the economy, and hired farmworkers are arguably the most at-risk worker population in agriculture. Surveillance for work-related illnesses and injuries (WRIIs) is critical for prevention; however, farmworkers are hard to count, the US surveillance system for illnesses and injuries in agriculture is fragmented, and Illinois state agencies engaged in agricultural safety and health have limited capacity to address occupational health. We describe developing a comprehensive surveillance program to target farmworkers and will present initial findings.

Methods

We are building a “system of systems approach” to more effectively use surveillance data to identify and mitigate WRIIs among agriculture workers in Illinois through (1) utilizing existing data systems that principally capture acute, moderate to severe illnesses and injuries and (2) establishing partnerships to integrate outpatient health data from clinics serving hired farmworker communities, which would capture minor and chronic injuries and health conditions.

Results

During the first year, we completed the preliminary analysis of agriculture-related illnesses and injuries in the following state-based data systems: police crash reports, workers’ compensation first reports of injury reports, hospital discharge, and Poison Center, as well as publicly available government data. We have also established partnerships with two clinic systems.

Discussion

Preliminary analysis of existing state-based and federal systems indicates an undercount of hired farmworkers and their WRIIs. Partnerships with local community clinics offer a promising means of furthering farmworker surveillance.

Conclusion

This research aims to expand epidemiological surveillance capacity for WRIIs among hired farmworkers to ultimately translate surveillance findings into actionable workplace safety programs.
O-343 DIFFERENCES IN HEALTH AND SAFETY HAZARDS RECOGNITION AND RISK PERCEPTION AMONG STEEL MANUFACTURING WORKERS
Authors: Marin Luz S , Zreiqat Majed , Minnick Wanda
Published: July 2024

Introduction

People may successfully manage to avoid injuries/illnesses because they perceive risk well enough to minimize it. This study aimed to examine the differences in safety hazards (more likely to cause work-related injuries) and health hazards (more likely to cause occupational diseases) recognition and their perceived risk among steel workers.

Methods

The study used a convenience sample of operators from three facilities in the Northeast of the USA. Participants responded to a 10-item self-administered online risk assessment survey. Hazard recognition was evaluated through four case images and two 1-minute case videos depicting actual operations/situations. The university’s IRB approved the study methods (22-170-EXT).

Results

A total of 104 male plant operators participated in the survey and identified a total of 596 hazards. The safety-related hazards (e.g., open moving parts and overhead crane movement) were the most identified. Heat stress and noise were the health-related hazards most recognized. In 36 cases, participants reported “no hazards present” in the case image/video showed. Risk perception scores indicated that workers had less fear and felt less vulnerable to health hazards.

Discussion

Discrepancies in hazard identification (safety vs. health) are expected since the emphasis is often on minimizing the exposure to conditions with immediate potential of causing injuries rather than on those with delayed consequences. This is problematic since workers could underestimate the risk associated with unidentified health-related hazards reducing their awareness and protection against.

Conclusion

Findings from this study are important for the development of customized safety interventions as well as in the training of middle managers with safety-related responsibilities.
P-517 ANALYSIS AND EVALUATION OF PREVENTION AND SAFETY POSTERS IN THE WORKPLACE IN MOROCCO
Authors: Manar Nadia , Bouri Hicham El , Laraqui Omar , Deschamps Frédéric , Laraqui Hossini Chakib El Houssine
Published: July 2024

Introduction

“A good sketch is better than a long speech”. The safety poster contributes to prevention through a change in behavior by acting on the sensitivity of those who look at it. The objective was to assess the degree of perception and understanding of worker safety posters

Methods

The study involved 631 people with at least two years of seniority. Four or five INRS posters and one from the Moroccan Ministry of Health were proposed for each of the seven sectors of activity: clothing, carpentry, welding, care, slaughterhouses, electricity and tanning. The themes of the posters relate to the nature of the most frequent risks in each sector. The evaluation of the 32 posters took place in two stages: -the installation of posters according to a reasoned choice according to time and place -a questionnaire in dialectal Arabic followed by an open interview including socio-demographic and professional information, criteria for analyzing the posters (perception, understanding, appreciation, usefulness, impressions aroused, general assessment and suggested improvements).

Results and discussion

illiterate workers prefer clear, simple representations in Arabic (messages written from right to left) and not including technical terms beyond their level of understanding. Metaphors are only understood by a minority of people. Workers prefer images that are adapted and directly related to their daily activities.

Conclusion

The poster remains a preferred prevention medium, but the messages disseminated must be adapted and well understood by the target population. The socio-cultural and religious context influences the perception of the message. It is to be taken into consideration to avoid unexpected interpretations.

Authors: Van Elk Fleur , Burdorf Alex , Lammers-van der Holst Heidi M , Robroek Suzan J W , Oude Hengel Karen M
Published: July 2024

Introduction

This study evaluates the effectiveness and implementation of PerfectFit@Night, an intervention to improve sleep, fatigue and recovery of night workers in healthcare.

Methods

PerfectFit@Night was implemented at twelve hospital departments that moved from the control to the intervention condition with two questionnaire measurements before and two measurements after the intervention. PerfectFit@Night lasted at least 3 months, and consisted of individual components (i.e., e-learning modules and targeted sleep coaching) and environmental elements (i.e., taking naps by using a powernap bed, healthy food provided during night shifts and a workshop on healthy rostering). The primary outcomes were sleep (night shift-related insomnia, sleep quality, sleep duration), fatigue and need for recovery. Mixed model analyses were performed to measure the outcomes over time. The implementation process was evaluated using the framework of Steckler and Linnan based on quantitative and qualitative data. Ethical approval was obtained.

Results

The first preliminary results showed that after three and six months of the intervention, the prevalence of night shift-related insomnia decreased with 11% (95% CI: -0.19, -0.04) and 13% (95% CI: -0.22, -0.05) respectively, while no effects were found for sleep quality and duration. After six months, the likelihood of more fatigue decreased (OR: 0.51, 95% CI: 0.28, 0.94) and the need for recovery decreased (β: -2.45, 95%CI: -4.86, -0.03).

Discussion

The final results of the analyses as well as the implementation of the intervention will be presented at the conference.

Conclusion

The preliminary results showed that PerfectFit@Night showed promising results for improving sleep, fatigue and recovery of night workers in healthcare.
P-525 SLEEP DEPRIVATION IN RESIDENTS. AN ACTIGRAPHIC STUDY ON ANESTHESIOLOGISTS AND OCCUPATIONAL HEALTH PHYSICIANS
Authors: Magnavita Nicola , Vacca Maria Eugenia , Meraglia Igor , Prinzio Reparata Rosa Di , Soave Paolo Maurizio , Stasio Enrico Di , Viti Giacomo
Published: July 2024

Introduction

Sleep deprivation poses a serious threat to doctors’ health and judgment. We sought to determine whether occupational medicine residents (OMRs) who don’t work nights have different physical and mental health than anesthesiology residents (ARs) who work only one night shift per week.

Methods

A questionnaire assessing sleep quality, sleepiness, exhaustion, occupational stress, anxiety, depression, and happiness was administered to a total of 21 ARs and 16 OMRs who were residents at a university general hospital. Residents were also asked to wear an actigraph to record their heart rate, steps taken, and time spent sleeping.

Results

The average amount of sleep time for ARs was 1 hour and 20 minutes less than for OMRs (p 0.001). Multiple regression analysis revealed that sleep quality was the major determinant of daytime sleepiness across the whole group. In addition, ARs were less happy than OMRs and were sleepier during the day.

Discussion

This study demonstrated that resident anesthesiologists who work night shifts, even if the number of such shifts is smaller than what is considered likely to alter biorhythms, sleep significantly less than their colleagues who are not engaged in night shifts and report a higher level of daytime sleepiness.

Conclusion

Given the cross-sectional nature of the study and the small sample size, these results should be interpreted with caution, but they should serve as motivation to encourage residents to practice good sleep hygiene.
P-526 THE IMPACT OF LONG WORKING HOURS AND THE USE OF WORK-RELATED COMMUNICATION DEVICES OUTSIDE REGULAR WORKING HOURS ON COMPUTER VISION SYNDROME AMONG WORKERS INTENSIVELY UTILIZING VISUAL DISPLAY TERMINALS
Authors: Shinhyeong Kim , Kang Seong-Kyu , Choi Won-Jun , Ham Seunghon
Published: July 2024

Introduction

Prior studies have explored psychological strain caused by work-related communication devices used beyond regular working hours. However, research on their direct physical impacts is limited. This study aimed to assess and compare the effects of long working hours and off-hours use of work-related communication devices on computer vision syndrome (CVS) symptoms among workers extensively using visual display terminals (VDTs).

Methods

This study utilized cross-sectional data from the 6th Korean Working Conditions Survey (KWCS), specifically responses from 16,304 workers using VDTs over half of work time. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression models, adjusting for gender, age, occupation, education, and income to examine influence of work-related communication device use during off-hours or long working hours on CVS symptoms.

Results

Compared to the reference group, those using work-related communication devices off-hours without long working hours showed higher risk of CVS symptoms (OR: 1.71, 95% CI: 1.57-1.86) compared to those who worked long hours but did not use work-related communication devices during off-hours (OR: 1.36, 95% CI: 1.05-1.76). Furthermore, the group that both worked long hours and used work-related communication devices outside of regular working hours exhibited the highest OR of CVS symptoms (OR: 1.91, 95% CI: 1.65-2.22).

Conclusion

Among VDT-intensive workers, the use of work-related communication devices outside regular working hours is associated with higher risk of CVS symptoms compared to working long hours alone. This suggests that when redefining working hours, it is necessary to consider work-related communication device use outside of working hours with regular work time.
P-527 RELATIONSHIP BETWEEN FLEXIBLE WORK ARRANGEMENT, WORKING HOURS, AND SLEEP PROBLEMS AMONG PAID KOREAN WORKERS
Authors: Han Eunseun , Kang Seong-Kyu , Choi Won-Jun , Ham Seunghon
Published: July 2024

Introduction

Since the COVID-19 pandemic, many companies and the Korean government have promoted flexible work hours. However, there is a lack of adequate research on this topic. This study explores the effects of flexible work arrangements on sleep disorders.

Methods

We analyzed the data from the 6th Korea Working Conditions Survey involving 31,384 workers. Flexible workers were defined by self-set hours. Sleep disorders were categorized as ‘difficulty falling asleep,’ ‘frequent waking during sleep,’ and ‘waking up feeling exhausted and fatigued.’ We used chi-square tests to analyze demographic and job-related differences. A multivariate logistic regression analysis was employed to identify any potential relationship between flexible work schedules and sleep disorders.

Results

The odds ratios were as follows: 1.27 (1.11-1.45) for ‘difficulty falling asleep’, 1.34 (1.19-1.51) for ‘frequent waking during sleep’, and 1.50 (1.36-1.66) for ‘waking up feeling exhausted and fatigued’. On average, flexible workers logged 36.97 (±13.30) hours per week, while non-flexible workers worked for 38.59 (±12.35) hours per week. Additionally, flexible workers reported working at night an average of 9.06 (±8.09) days per month, slightly fewer than the 9.20 (±6.36) days reported by non-flexible workers.

Discussion

Notably, despite having shorter work hours and fewer working at night, flexible workers displayed a significantly higher likelihood of experiencing sleep problems compared to their non-flexible counterparts.

Conclusion

While flexible workers gained advantages from reduced working hours and working at night, they still faced a heightened risk of sleep disturbances. Further research is imperative to determine the causality and underlying factors responsible for this discrepancy.
P-531 PERCEIVED HEALTH IMPACT OF NIGHT WORK – A QUALITATIVE STUDY FROM THE PERSPECTIVE OF NIGHT WORKERS
Authors: Proper Karin , Loef Bette , Van Kerkhof Linda , Bosma Esmee
Published: July 2024

Introduction

A large fraction of the workforce works at night. While epidemiological evidence indicates that night work has a severe impact on health, insight into empirical experiences of night workers themselves is limited. Therefore, the aim of this study was to provide insight into the experiences of night workers on the impact of night work on their physical, mental, and social health. Furthermore, night workers’ views on the appreciation of night work were explored.

Methods

Data was collected through in-depth semi-structured peer-to-peer interviews (n=25). For this, 5 night workers were trained to conduct each 5 interviews with night-working colleagues (peers) about their experiences with the health consequences of night work. Transcripts were analyzed utilizing thematic analysis using inductive, iterative coding. The Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist was followed.

Results

Night workers experienced reduced work capacity and daily functioning, decreased energy and fatigue, decreased sleep quality, decreased concentration and memory and emotional dysregulation, and a mental focus in preparation for the upcoming night work period. Additionally, the experiences showed social challenges, reduced need for social contact and an often-negative impact on the perceived quality of family life. Intra-personal differences were apparent in the appreciation of night work: e.g., increased daytime flexibility, a calmer working atmosphere, versus a lack of social-cultural understanding, and night work as a mandatory labor requirement.

Discussion/Conclusion

The overall experiences unfold a diverse, predominantly adverse, impact of night work on mental, physical, and social health. Furthermore, intra-personal differences in the appreciation of night work need to be contemplated conscientiously.
P-532 VITAMIN D LEVELS IN NIGHT SHIFT WORKERS AND CORRELATION WITH CANCER DISEASES
Authors: Seco Julia , Puig Marina Rovira , Maria Rosa
Published: July 2024

Introduction

Preliminary studies suggest that night shift work is associated with a desynchronization of metabolism of vitamin D, possibly explaining the increased risk of infection, cardiometabolic disorders, and cancer in shift workers.

Methods

This study included 49 male rotating shift workers from a car industry in Barcelona, Spain, sampled twice toward the end of a 3-week night shift (22:00-06:00 h) and a 3-week day shift (06:00-14:00 h) rotation. We collected two blood samples per worker, at the start and end of each shift. We measured levels of 25 (OH)D and 1,25 (OH)D using LC-MS/MS and applied linear mixed models to examine within-person associations between shift work and analytes’ concentrations, comparing samples taken at 06:00 h on a day and night shift, adjusting for hours of daylight.

Results

We observed lower levels of 25 (OH)D in the day shift compared to the night shift. However, levels of 1,25 (OH)D were only detectable in 67% of participants, and lower levels were observed in the night shift compared to the day shift.

Conclusion

Even though night shifts workers have been reported to have higher risk for endocrinometabolic disorders, they have slightly higher levels of 25 (OH)D. The different patterns of 25 (OH)D and specially 1,25 (OH)D need to be further studied given the inconsistency between 25 (OH)D and 1,25 (OH)D. Few studies have annalized 1,25 (OH)D, the active form of vitamin D, which may be a marker for diseases.

Authors: Ayed Wiem , Brahim Dorra , Youssef Imen , Mersni Mariem , Bahri Ghada , Bensaid Hanene , Mechergui Najla , Ladhari Nizar
Published: July 2024

Introduction

Shift work leads to sleep deprivation and sleep disruption of the immune, inflammatory and endocrine systems. Some chronic inflammatory diseases can be decompensated or exacerbated.

Aims

To study the impact of chronic inflammatory diseases on the medical fitness for work.

Methods

Retrospective cross-sectional study which had included shift workers who had consulted the Occupational Medicine Department at the Charles Nicolle Hospital over a seven-year period from January 2016 to June 2023 for a medical decision on their fitness for work.

Results

Among 243 shift workers, 9% (n=28) had chronic inflammatory diseases consulted by our department. The average age was 38 ± 7 years. The sex ratio (M/F) was 0.47. The most common professional sectors were: health (61%), industry (21%) and services (11%).The most occupied positions were: blue collar workers (25%), nurses (25%), doctors (18%).The average professional seniority was 10±6 years [1-22]. The most common chronic inflammatory diseases presented by the patients were: multiple sclerosis (22%), ankylosing spondylitis (18%), rheumatoid arthritis (11%),myopathy (11%) and scleroderma (8%). A definitive avoidance of shift work was indicated in 93% of the cases.

Conclusion

Special medical surveillance for workers with chronic inflammatory diseases by the occupational physician is necessary.
O-354 COMPENSATION CASES AND DISABILITY CLAIMS AMONG OVERSEAS FILIPINO SEAFARERS: A COMPREHENSIVE REVIEW AND ANALYSIS
Authors: Asuncion Ronahlee
Published: July 2024

Introduction

The maritime industry is a critical component of the global economy, with Filipino seafarers playing a pivotal role as a skilled and dedicated workforce. However, this demanding profession comes with inherent risks and challenges, leading to various occupational injuries and disabilities.

Methods

This study examined cases related to compensation and disability claims of overseas Filipino seafarers decided by the Philippine Supreme Court from 2010 to 2020. Trends and patterns were identified to determine the common causes of accidents and injuries at sea. Secondary data were likewise used to further support the study.

Results

Findings indicate that compensation cases and disability claims among Filipino seafarers are multifaceted issues influenced by factors such as long working hours, fatigue, insufficient training, and inadequate safety measures on board vessels. Mental health-related claims emerged as a notable concern, highlighting the need for improved support and awareness in addressing psychological well-being at sea.

Discussion

The problem in compensation cases and disability claims of Filipino seafarers is complex and involves several challenges that hinder their access to fair and timely compensation for work-related injuries and disabilities. Seafarers seeking redress are faced with delayed processing, insufficient training and safety measures, mental health concerns, and jurisdictional challenges among others.

Conclusion

Addressing these problems requires collaborative efforts among relevant stakeholders, including government agencies, shipping companies, labor unions, and international organizations. By improving regulations, streamlining processes, enhancing safety measures, and providing better support for seafarers’ well-being, it is possible to ensure fair compensation and improved outcomes for Filipino seafarers facing work-related injuries and disabilities.
O-355 DETERMINANTS OF OCCUPATIONAL INJURIES AMONG INFORMAL CONSTRUCTION ARTISANS IN OSUN STATE NIGERIA. A MIXED-METHODS SURVEY OF CARPENTERS AND BRICKLAYERS
Authors: Ojo Temitope , Naicker Nisha
Published: July 2024

Introduction

Occupational injuries (OI) remains a global health issue, claiming approximately 1000 lives daily. This study assessed the factors influencing OIs among carpenters and bricklayers who are informal artisans in Nigeria.

Methods

This mixed-methods survey was conducted in Osun state Nigeria. The quantitative component entailed a comparative cross-sectional study of 421 bricklayers and 425 carpenters. Information on socio-demographics and, OI prevalence was obtained using a semi structured questionnaire. The qualitative aspect comprised 12 focus group discussions among artisans.

Results

All respondents were male. The mean age was 51.3.7±14.7 years for bricklayers and 50.0±11.5 years for carpenters. The 3-month. prevalence of OI was 39.9% for bricklayers and 51.8% for carpenters. Factors associated with OI among bricklayers included being aged 20-39 years (AOR:6.2, 95%CI:2.7-14.2) and 40-59 years (AOR:2.7, 95%CI:1.4-5.4), earning less than N50,000 ($67) monthly (OR:2.6, 95%CI:1.3-5.5), earning N50,000-N100,000 ($67-$133) monthly (AOR:2.8, 95% CI: 1.3-5.9), and handling ≥200kg per day at work (AOR:1.9, 95% CI:1.1-3.2). For carpenters, factors associated with OI were being aged 20-39 years (AOR:3.7, 95% CI:1.6-8.6), age 40-59 years (AOR:1.9, 95%CI:1.02-3.5), and handling 100-199kg per day at work (AOR:2.1, 95%CI:1.1-3.9). FGD findings revealed that use of substandard building materials, poor use of personal protective equipment and working at heights may predispose to OIs.

Discussion and conclusion

The burden of OI is high among informal construction artisans in Nigeria. Safety interventions should target persons < 60 years, those handling heavy weights at work (>100kg) and bricklayers earning < N100,000 ($133) monthly. Emphasis should also be placed on use of safety equipment and ensuring standards of building materials.

Published: July 2024

Introduction

Technological processes in the construction industry accompanied by heavy construction equipment are risks for occupational accidents and work-related diseases. The aim of the present study is to set up the correlation between risk factors and the incidence of socially significant diseases.

Materials and methods

For the purpose of the study 362 workers in the construction sector were surveyed. The information obtained was processed using a descriptive and analytical methods. The descriptive statistics and analysis of relationships between individual statistical series were conducted throughout the Pearson 2 test for attributive data, i.e. T--test and Pearson correlation test for numerical series.

Results

All surveyed participants were Male and the mean age of the respondents was 51.1±9.3 years. The working experience of the position held was 26.1±8.2 years. The distribution by job title shows that 278 of the respondents were construction workers and those working in administration were 84. A correlation was established - the higher the prevalence of cardiovascular diseases and arterial hypertension diagnosed by a physician, the higher the blood pressure values among registered construction workers

Discussion

The most common risk factors for the respondents from both groups indicated were the cardiovascular diseases with the possible key role of the work environment factors in the multicausal etiology of the disease.

Conclusion

Measures need to be taken at all levels to reduce cardiovascular diseases among construction workers such as: introducing health promotion programmes aimed at eradicating harmful habits and conducting regular preventive check-ups.

Authors: Houria Amira , Bani Meja , Hamdouni Mongi
Published: July 2024

Introduction

fatal occupational accidents (foas), due to their harmful consequences on both workers and the country’s economy, are a current issue that requires significant attention.

Methods

this was a retrospective study, including all cases of foas reported to the regional offices of the national health insurance fund over a 2-year period (2020-2021).

Results and discussion

we collected 161 cases during the study period, with an average annual rate of 80 accidents and a monthly rate of 6 accidents. A majority of the cases were male (95.65%), with an average age of 44 years and an average work tenure of 6 years, of which 45.3% had less than one year of experience. Unskilled workers were the most affected (65.2%), especially in the construction (27%) and electrical industry and transportation sectors, which were identified as high-risk sectors for foas. Falls from heights were the most common type of accident (21.6%), followed by simple impacts and/or impacts from moving objects (16%) and electrocutions (11.8%). Non-traumatic fatal occupational accidents accounted for 18.6% of cases, with polytrauma in 60.86% of cases.

Conclusion

The consequences of FOAs warrant consideration in terms of occupational risk management and the promotion of prevention involving all stakeholders, including employers, employees, occupational physicians, insurers, and legislators.

Authors: Minami Chiharu , Takamatsu Misako , Ohashi Yuko , Mori Reiko , Nakashima Rieko , Mizutani Seiko
Published: July 2024

Introduction

The development of human resources who learn to act proactively by utilizing the health literacy support provided at the time of recruitment is vital for occupational health. This study aims to review past studies on health literacy among university students and new employees, organize the findings, and provide suggestions that can support occupational health nurses in improving the health literacy of new employees.

Methods

The web version of “The Japan Medical Abstracts Society” served as the database for this literature review. The keywords used were “occupational health,” “new employees,” and “college students.” A review matrix was constructed to organize the data.

Results

The literature search yielded no results on “health literacy” for “new employees.” For “occupational health” as well, except for a few, scattered studies, no systematic studies on “new employees” and “health literacy” were found. Although there were more studies on health literacy among university students than on occupational health, none of them investigated systematic initiatives or changes over time.

Discussion and Conclusion

The results indicate that, to support occupational health nurses who focus on the health literacy of students during their time in college, it is important to encourage the resolution of individual and group health issues and support good health by utilizing the opportunity for a health checkup at the time of being hired.

Published: July 2024

Introduction

Nurses are constantly under pressure in their work, not only due to the responsibility but also to the immense tasks performed daily in caring for patients. The correlation between high workload and burnout is undeniable. To prevent distress and absenteeism, it is vital to evaluate nursing workload. Workload measurement instruments serve as a decision support tool, crucial for effective human resource management. However, the tool’s effectiveness relies on participation of nursing staff, guaranteeing data collection. In pursuit of practical applicability, it is imperative to capture perspectives and benefits perceived by nursing staff and managers. Doing so, strategies can be devised to strengthen adherence, increasing the tool’s usage.

Methods

Through a focus group, based on semi-structured interview with nursing staff and managers; this project explores perceptions, concerns, and benefits of nurse operation workload model application. The interviews will be transcribed, organized using knowledge mapping and analyzed based on qualitative content analysis.

Results

The preliminary results reveal that nursing staff and managers identify the instrument as a tool for improving health and safety measures in the workplace, leading to equally distributed workload, enhancing job satisfaction and staff well-being.

Discussion

Mapping technique provide insights about the topic and send seeds for the construction of a bigger project. Collected data establish a basis for dialogues about implications of workload on conceptions of job satisfaction and overall welfare.

Conclusion

This study highlights nursing staff perspectives on the nurse operation workload model. These insights amplify nurse well-being via equitable task allocation, advancing healthcare delivery and sustaining professional resilience.
O-367 EVALUATING THE EFFECTIVENESS AND COMFORT OF NEW MOISTURE BARRIERS AND DESIGNS FOR FIREFIGHTERS’ PERSONAL PROTECTIVE CLOTHING
Authors: Gauvin Chantal , Marchand Denis , Landry-Duval Marie-Anne
Published: July 2024

Introduction

Firefighters face heat stress in the course of their duties, exposing them at increased risk of cardiovascular accidents, their most common cause of death. Firefighters’ personal protective clothing (PPC) contributes to the physiological stress by retaining body heat and moisture within the various layers, preventing sweat evaporation and thus increasing body temperature and the risk of cardiovascular events.

Methods

The aim of this study was to determine the effects of new moisture barriers and firefighter PPC designs during physiological, psychophysical and movement assessment.

Results

Ten participants performed treadmill walking tests in a climate chamber (35°C, 50% relative humidity). Five PPC were tested, comprising different combinations of two moisture barriers, two designs (Traditional, Innovative), and an air circulation system. Oxygen consumption, heart rate, core temperature, humidity and temperature inside the PPC, psychophysical perceived exertion and ease of movement were measured. The modifications to the outer shell of the Innovative model did not reduce physiological stress during exercise. The temperature in the inner layer of this model was significantly higher than in the Traditional model. The modifications were more uncomfortable and restrictive during movements. Perceived exertion showed a significant difference between the two moisture barriers. The air circulation system did not reduce thermal stress, and seemed more restrictive during movements. The results of this research demonstrate the importance of improving the effectiveness of PPC.

Discussion-Conclusion

Measurements of temperature and relative humidity inside layers seem to be a good indicator for assessing the PPC performance in reducing thermal stress associated with the microclimate formed inside the PPC.

Authors: Ningsih Sri Utami , Suraya Anna , Danukusuma Lelitasari , Sulandari Uci
Published: July 2024

Introduction

Dialysis for end-stage chronic kidney disease (CKD) represents the second highest expenditure of Indonesian Health Insurance. This study aims to investigate the prevalence of CKD among workers exposed to excessive heat and explore the associated risk factors.

Method

This study was conducted at an industry in West Java, between March and June 2023. Secondary data was obtained from the annual Medical Check-Up 2022-2023 data and heat measurements data in 2017. CKD was defined as having a creatinine value >1.2 in two consecutive years. The data analysis operated Chi-square and logistic regression.

Results

Subjects eligible for this study totaled 675, of which 99.7% were male and 49% were >40 years old. Most workers (96.1%) had been exposed to temperatures exceeding 28°C, 47% were classified as obese, 16.7% had hypertension, 5.5% had diabetes mellitus, and 63.9% has worked for more than 5 years. The prevalence of CKD was 5.5%. The relative risk (RR) for workers older than 40 years to develop CKD was 2.4 (95% CI 1.11-5.11), while the RR for obesity was 2.3 (95% CI 1.07-5.08), and the RR for hypertension was 3.2 (95% CI 1.58-6.65). All workers diagnosed with CKD had been exposed to temperatures exceeding 28°C and worked for more than five years.

Discussion

The CKD prevalence found in this study was higher than Indonesian population. The association with excessive temperature could not be discovered because almost all workers were exposed to it.

Conclusion

Further research is required to understand the impact of heat on CKD among workers.
O-373 PREVENTING EXPOSURE TO THE SUN AT WORK: PRACTICES OF OCCUPATIONAL HEALTH PHYSICIANS AND NURSES IN FRANCE
Authors: Nourry Nathalie , Berthomieu Mélodie , Michel Jean , Gonzalez Maria
Published: July 2024

Introduction

Workers exposed to the sun’s natural rays will be increasingly so as a result of global warming. In France, we have national prevention campaigns aimed at the general population, but not at workers. The aim of our work is therefore to study whether, despite the absence of a national campaign, occupational health services have taken up the subject.

Methods

A self-administered questionnaire was distributed to occupational health physicians and nurses at the national congress in June 2022. The questionnaire assessed their socio-demographic characteristics, their perception of solar UV risk, any additional medical training they had received, and their primary, secondary and tertiary prevention practices.

Results

265 doctors and 119 nurses responded. Two-thirds of them identified and noted the solar risk in their companies. At organizational level, breaks, working in the shade or outside of southern hours were most often recommended (40-56%). Advice on personal protective equipment is frequent (50-68%). Around 15% offer training (courses or flyers). Factors influencing the implementation of primary prevention actions were a history of cancer in one of their workers (OR=1.57 [0.98-2.52]), and working in a very sunny area (OR=1.55 [0.94-2.56]). The performance of screening was influenced by the seniority of the healthcare provider (over 16 years OR=2.39 [1.29-4.41]), by his/her profession (doctor OR=2.23 [1.24-4.01]), and by the absence of specific training (OR=0.57 [0.34-0.95]).

Discussion-Conclusion

The occupational risk of solar UV is known, but prevention remains inadequate. Various initiatives have been proposed including training for occupational health professionals. An action within the Grand Est area’s regional occupational health plan is currently underway in France.
