SS66-03 TOLUENE USE AND EXPOSURE: IMPLICATIONS FOR THE VISUAL HEALTH OF RESTORERS OF WORKS OF ART
Authors: Molina Graciela , Taboadela Claudio
Published: July 2024

Introduction

The use of toluene and other organic solvents for cleaning works of art has been a common practice since the 1990s. Toluene is a neuronal inhibitor associated with progressive damage to the central and peripheral nervous systems (CNS, PNS) and its toxicity can occur through inadvertent inhalation. The objective of this study is to consider the alterations in vision produced by toluene exposure in restorers of works of art, as an occupational disease.

Materials and Methods

A bibliographic search was carried out in specific restoration books and electronic articles published from 2010 to 2019. The electronic articles were found in the Elsevier, Scielo, PubMed and Research Gate databases. The search terms were ‘restoration of works of art, ‘toluene’, ‘organic solvents’, ‘occupational poisoning’, and ‘dyschromatopsia’ (a form of colour-blindness).

Results

Restorers of works of art are exposed to low doses of toluene for months or years. Chronic exposure may cause damage of CNS due to the destruction of the white matter as well as dysfunction of the PNS. Toluene exposure can affect the optic nerve and the macular area of the retina possibly due to mitochondrial poisoning that inhibits oxidative phosphorylation. The symptoms presented include blurred and distorted vision and dyschromatopsia.

Conclusions

The alteration of the perception of colours has a direct impact on the work of art restorers because it decreases their work capacity. Early detection of dyschromatopsia should therefore be contemplated in the medical surveillance of art restorers.
SS70 WORKERS' EXPOSURE SURVEY ON CANCER RISK FACTORS – DISCUSSION ON FINDINGS
Authors: Cavet Marine
Published: July 2024

With cancer accounting for half of all work-related deaths in the European Union (EU) and other developed countries, data on cancer-causing exposures at work and information on prevention measures used at the workplace is essential to improve and preserve the safety and health of workers.

EU-OSHA led in 2023 the largest worker survey conducted in Europe to assess exposure to a range of known cancer risk factors, including for example asbestos, benzene, chromium (VI), diesel engine exhaust emissions, nickel, respirable crystalline silica, ultraviolet radiation or wood dust. In total, 24,402 workers in all occupations were interviewed in six EU countries. The survey uses an occupational exposure assessment tool for epidemiological studies (OccIDEAS) to assess the probability and level of exposure to the selected cancer risk factors based on respondent answers.

A similar worker survey has been implemented in New Zealand: the New Zealand carcinogens survey 2021, which also used OccIDEAS to estimate the prevalence of carcinogen exposure.

After explaining the methodology applied, key findings from both the European Union and New Zealand will be presented. A special focus will be given to the workers exposed to ionising and ultraviolet radiation in the EU, and to the workers in the health and social care sector and their exposure to cancer risk factors.

Authors: Irastorza Xabier , Vilahur Nadia , Cavet Marine , Schneider Elke
Published: July 2024

Introduction

The European Agency for Safety and Health at Work (EU-OSHA) has coordinated the development and implementation of a large survey, the Workers’ Exposure Survey on cancer risk factors in Europe (WES), in six European Union (EU) countries: Finland, France, Germany, Hungary, Ireland and Spain.

Materials and Methods

WES uses the Occupational Integrated Database Exposure Assessment System (OccIDEAS), which has been customised in terms of the questions asked to the workers and the rules underlying the assessment of the probability of exposure, to be relevant to the EU context of work and occupational health and safety legislation. For each respondent, the survey provides information on probable exposure to 24 cancer risk factors relevant in the EU context, including chemical and physical agents, as well as demographic data and self-reported information on existence or use of preventive measures at work, such as ventilation system and respiratory protection. Several tests were carried out to assess translation issues and the clarity of the questions, and to test exposure assessment and questionnaire performance, among others. The survey fieldwork lasted 20 weeks, from September 2022 to February 2023. Trained interviewers conducted interviews over the telephone with workers aged 15 years or more. Response rates were ranging between 7% in Ireland and 22% in Finland.

Results

After completion of fieldwork and data quality control, a total of 24,402 valid interviews were obtained for analysis.

Conclusions

WES data should contribute to a better understanding and increase awareness of cancer risks at the workplace, enhancing prevention and risk management across the EU.
SS71-01 MENTAL HEALTH: A GLOBAL OVERVIEW
Authors: Caraballo-Arias Yohama , Marquez-Medina Luis Guillermo , Rincón-Sarmiento Juan Ignacio , Cuervo Diana Elizabeth
Published: July 2024

Introduction

Modern work-life challenges affect workers’ mental health. According to the World Health Organization (WHO) in 2019, one in eight people in the world suffered from a mental disorder: equivalent to 970 million people. The most common were anxiety and depressive disorders spread all over the world. During the COVID-19 pandemic, the problem became more visible. Some authors even called them the ‘emerging pandemic’.

Materials and Methods

Only a few nations have regulations on mental health issues and a few include mental and behavioural consequences on their occupational diseases list. The International Labour Organization (ILO) only covers two mental and behavioural disorders, such as stress post-traumatic disorder and other disorders on their occupational diseases list, revised in 2010.

Results

Colombia has six diseases on its list and has an important role on regulations on prevention and health monitoring private and public in sector, the processes of occupational disease qualification derived from this exposure is increasing, which represents a challenge, where the enterprises will play an important role in prevention and early diagnosis.

Conclusions

Occupational safety and health professionals play an important role in increasing awareness, early detection of mental health symptoms, and referral to the proper specialist for a proper diagnosis, treatment and re-insertion into the workplace. The main challenges regarding mental health issues are objective tests to make the proper diagnosis, lack of well-trained mental health professionals, lack of regulations, and the non-occupational sources that are part of the root causes of mental health issue, making these diseases (as many) multifactorial entities.

Authors: Denny Hanifa M , Widjasena Baju , Lestantyo, Suroto Daru , Setyaningsih Yuliani
Published: July 2024

Introduction

In the dynamic realm of modern agriculture, the responsible use of pesticides and chemicals stands as a cornerstone for achieving optimal crop yields and ensuring food security.

Materials and Methods

We conducted a multi-year project to illuminate the long-term education for vegetable farmers concerning their extensive use of pesticides and other chemicals in Brebes, Demak, and Semarang - Indonesia. The project aimed to equip farmers with the understanding and skills to work safely and healthily with pesticides and chemicals.

Results

Occupational, safety, and health education for farmers demands a balanced approach that aligns with their interests, gradually introducing important topics like risk awareness. The sessions were conducted to ensure engagement without disrupting productivity. Recognizing their contribution and providing incentives like transportation and meals underscores our appreciation for their time and commitment. This comprehensive strategy fosters a learning, safety, and sustainability culture within the farming community. This approach fosters a sense of partnership, encouraging farmers to embrace education to enhance their wellbeing and agricultural practices actively.

Conclusions

Educating farmers with low education attainment is a multi-faceted effort that requires careful consideration of their preferences, work commitments, and the significance of their participation. By tailoring educational sessions to align with their interests and gradually introducing critical topics such as risk awareness, we can effectively capture their engagement without hindering productivity. The key lies in creating captivating learning experiences that seamlessly integrate with their daily routines.

Published: July 2024

Introduction

An intensified and increasingly demanding and digitalized working life, accelerated by the COVID-19 pandemic, requires new approaches to improve health and wellbeing at work and beyond. This presentation provides an overview of 5-years research progress on needs-based crafting. The Identity-based Integrative Needs Model of Crafting provides the theoretical basis for this work and underscores workers' pivotal role in shaping their environment at work and outside work. More specifically, needs-based crafting refers to workers’ efforts to actively adjust their work and off-job activities with the aim to satisfy their psychological needs for detachment, relaxation, autonomy, mastery, meaning and affiliation.

Materials and Methods

The presentation of results from various empirical data collections spans a range of organizational contexts and diverse global work cultures (e.g., Japan, Finland, Switzerland). Varied methodological approaches such as longitudinal surveys spanning several months and real-time ecological momentary assessments as well as intervention studies offer unique insights into when, how and why people craft.

Results

The findings from this research project unravel crafting's influence on health, wellbeing, and the role of delineations between life domains. Predictive factors, encompassing both persistent and situational elements, are systematically examined, contributing to a comprehensive understanding of crafting's dynamic nature.

Conclusions

The presentation culminates in providing insights into crafting processes, their impact on health, wellbeing, and performance. Beyond academia, we underscore crafting's important role in recalibrating people’s work-life equilibrium.
O-001 DECREASED WORKABILITY IS ASSOCIATED WITH TECHNOSTRESS, POOR SLEEP QUALITY AND LOWER COGNITIVE FUNCTIONING IN AGED WORKERS. DATA FROM AN ITALIAN OCCUPATIONAL EPIDEMIOLOGICAL STUDY

Published: July 2024

Introduction

Average age of the workforce is constantly rising. Meanwhile, current evolutions in the workplace are characterized by an increase in the use of digital technologies, requiring greater cognitive skills and time flexibility. We designed a study to evaluate the wellbeing of workers over 50 years old, through assessment of work-ability, cognitive functioning, and sleep quality.

Methods

We enrolled workers, aged over 50, performing both physical/manual labor undergoing the occupational health surveillance. We collected occupational data, workability (WAI), technostress, cognitive functioning (Stroop Color and Word test, Corsi’s block-tapping test, Digit-span test), sleep quality (PSQI, ISI, FIRST). Student t-test investigated differences between blue collars workers (BCWs) and white collars workers (WCWs). The associations between workability, technostress, sleep quality and cognitive functioning were assessed through regression models including moderators.

Results

A total of 468 workers have been enrolled. Workability, sleep quality, cognitive skills and technostress were, on average, significantly different between BCWs and WCWs. Poorer sleep quality results were associated with lower workability (p<.001) and such a relationship was stronger for BCWs. Better cognitive functioning was related to higher WAI, while higher level of technostress was associated with decreased WAI.

Discussion

We observed interactions among workability, sleep disturbances, cognitive performance and technostress in workers >50 years old. These relationships were particularly marked among BCWs.

Conclusion

Our findings could stimulate possible interventions and protective measures focused intervention to ensure aged workers’ well-being. Blue-collar workers should benefit from tailored intervention to sustain workability and prevent technostress, considering the role of healthy sleep habits promotion.

Authors: Solovieva Svetlana , De Wind Astrid , Undem Karina , Planck Christian Dudel Max , Imehlum Ingrid Mehlum , Van den Heuvel Swenne G , Robroek Suzan J W , Leinonen Taina
Published: July 2024

Introduction

To improve the insight on differences in working life expectancy (WLE), healthy WLE (HWLE) and working years lost (WYL) by education, occupational class and income while using different ways of measuring and estimating WLE and to define future research needs.

Methods

A systematic search was carried out in Web of Science, PubMed and EMBASE and complemented by relevant publications derived through screening of reference lists of the identified publications and expert knowledge. Reports on differences in WLE, HWLE or WYL by education, occupational class or income, published until November 2022, were included. Information on socioeconomic differences in WLE, HWLE and WYL was synthesized.

Results

A total of 26 reports from 21 studies on educational and occupational class differences in WLE, HWLE or WYL were included. No reports on income differences were found. On average, WLE in persons with low education is 30% (men) and 27% (women) shorter than in those with high education. The corresponding numbers for occupational class difference were 21% (men) and 27% (women). Low-educated persons were expected to lose more working years due to unemployment and disability retirement than high-educated persons.

Discussion and conclusion

The identified socioeconomic inequalities are highly relevant for policy makers and pose serious challenges for equitable pension policies. Many policy interventions aimed at increasing the length of working life follow a one-size-fits-all approach which does not take these inequalities into account. More research is needed on socioeconomic differences in HWLE and potential influences of income on working life duration.
O-007 CLIMATE CHANGE, AEROALLERGENS AND OCCUPATIONAL HEALTH: A BETTER INTEGRATION FOR A BETTER MANAGEMENT OF ALLERGIES IN THE WORKPLACES

Published: July 2024

Introduction

The development of aerobiology in the last years represents an additional support to study the effects of climate change (CC) on human health. It is well known that higher temperatures increase the likelihood of extreme meteorological events, entail prolonged pollen seasons, and promote the interaction between pollen and chemical pollutants. Workplaces are suitable to plan more targeted studies on CC, aeroallergens and allergic diseases.

Methods

Since 2014, occupational allergies and CC were included in INAIL research activities with a multidisciplinary approach. Focus on occupational allergies based on literature analysis, Hirst and real-time aerobiological methods as well as serum multiplex methodologies is provided.

Results

Taking into account the seasonality, aerobiological outdoor samples were analyzed and pollen species characterized. The indoor aerobiological monitoring highlighted the association between occupants and pollen levels. Sensitisation to plant allergens was more frequent than that to other allergens.

Discussion

Guidelines published by WHO in September 2021 included among research priorities multiple exposures to air pollutants (including pollen and other aeroallergens), interaction with other environmental and climatic factors, improvement of methodological aspects. Our results on aerobiology and CC stress the value of these issues and the role of occupational exposure. Aerobiological monitoring, proper health surveillance and allergen testing should be combined for a better management of occupational health concerns.

Conclusion

A multidisciplinary approach applied in different working settings is needed to address the role of environmental, occupational and individual variables. The results confirm the importance of CC as a modulator of allergic responses and related diseases.

Published: July 2024

Introduction

Occupational exposure to crystalline silica is associated with an elevated risk of autoimmune diseases in susceptible individuals, yet underlying mechanisms, likely influenced by gene-environment interactions, remain unclear. We aimed to investigate the immunotoxicological effects of exposure to crystalline silica considering the effect of genetic background in C57BL/6J and NOD/ShiLtJ mice.

Methods

C57BL/6J and NOD/ShiLtJ mice were oropharyngeally exposed to 4mg quartz (median size about 2 µm) with animal ethics committee approval of KU Leuven (P111/2021). Ten weeks post-exposure, bronchoalveolar lavage fluid (BALF), lungs and serum were collected to evaluate inflammatory cell count, lung histology, lung fibrosis and antinuclear antibody (ANA) presence.

Results

Silica exposed mice developed a local inflammatory response characterized by inflammatory infiltrates, recruitment of macrophages/neutrophils and mild lung fibrosis, which was more pronounced in the NOD/ShiLtJ mice. In BALF, the silica-exposed NOD/ShiLtJ mice showed significantly high ANA scores with about 40% of mice reaching a score of 3-4, while silica-exposed C57BL/6J mice had lower scores, only reaching up to 2. Silica-exposed NOD/ShiLtJ mice also developed systemic ANAs present in serum, with scores reaching up to 4, whereas silica-exposed C57BL/6J mice only reached scores up to 2-3.

Discussion

The autoimmune-prone background of NOD/ShiLtJ mice characterized by an H2(g7) MHC haplotype and genetic variants impacting tolerance and T cell functioning seems to render them more susceptible to an inflammatory phenotype facilitating the development of autoantibodies.

Conclusion

The autoimmune-prone genetic background of the NOD/ShiLtJ mice appears to be a critical factor contributing to their susceptibility to develop silica-induced features of autoimmune disease.

Published: July 2024

Introduction

Allergic rhinitis (AR) is a common disease of the upper respiratory tract. Its severity is closely related to its impact on both quality of life and occupational performance. The risk of chronic rhinitis may be increased by active smoking. However, conflicting results were obtained. To study the relationship between active smoking and occupational AR severity.

Methods

This is a cross-sectional study including all patients who had consulted in the occupational medicine department at a Tunisian Hospital for occupational AR between 2011 and 2022. The assessment of the severity of AR was made by the PAREO score and rhinomanometry.

Results

The population included 196 cases of occupational AR with a mean age of 39.69 ± 7.9 years and a clear female predominance (65.3%). The most represented sector of activity was the textile sector (49.5%) with a professional seniority of 15.2± 8.1 years. Active smoking was reported in 19.4% of cases. The PAREO score was 5.78 ± 1.6. Rhinitis was severe in 34.7% and 27% according to PAREO score and rhinomanometry respectively. A significant association between the PAREO score and active smoking was reported (r = 0.28, p=0.027). However, no association was found between active smoking and the severity of AR measured by rhinomanometry.

Discussion and conclusion

Active smoking can have harmful consequences in the aggravation of occupational allergic pathologies, especially rhinitis. Community awareness should be raised about the effects of smoking on AR, and the society should be trained for smoking cessation.

Introduction

Given the diversity of occupational allergens, the allergic contact dermatitis (ACD) is the main cause of occupational dermatitis. Experiencing a quasi-permanent pruritus or visible lesions can impair quality of life. The aims of our study are to investigate the occupational origin of ACD and evaluate its impact on work.

Methods

We conducted a cross-sectional study on patients patch-tested for ACD lesions. Data were collected using a synoptic form completed to patch-tests results.

Results

Our population included 32 patients (sex ratio 0.88) with a mean age of 41.6 years. Eczema was the major complaint (84.4%), followed by urticaria (12.5%) and dyshidrosis (6.5%). The most prevalent allergens were nickel (25%), Potassium-dichromate (18.75%) and cobalt (15.6%). Lesions were lichenified, vesicular and erythematous in 35%, 30% and 25% of cases respectively, mostly located on the upper limb (71.9%). The patch test was positive in 71.9% of cases, more than half of them were consistent with the occupational exposure history. ACD had an occupational impact in 53.1% of individuals: recurrent work interruptions (34.4%), job retraining (18.75%), early retirement (3.1%) and definite cessation of work (3.1%).

Discussion

Occupational skin diseases are the most reported occupational diseases, the hands are the most intensely exposed sites to contact allergens. ACD mostly occur in hairdressers, metal workers, healthcare workers, often leads to prolonged sick-leave and frequently requires long-term treatment.

Conclusion

Investigating an eventual occupational origin of ACD can be challenging. Although treatment may provide temporary relief, identifying the culprit allergen may help the clinician counsel on how to avoid exposure.
P-012 SOLAR RADIATION AND IMMUNE EFFECTS: IMPLICATIONS FOR OUTDOOR WORKERS IN LIGHT OF A CHANGING CLIMATE
Authors: Grandi Carlo , Lancia Andrea , D’Ovidio Maria Concetta
Published: July 2024

Introduction

UV radiation is recognized to alter the immune response. In particular, both UVB and UVA stimulate innate immunity while tend to inhibit adaptive immunity. UVB and UVA are present in the solar spectrum, whose targets are skin and eye. Consequently, skin immunity is affected by solar UV radiation and this may lead to both local and systemic effects. Outdoor workers are variably exposed to Solar Radiation (SR) and to the impact of Climate Change (CC).

Methods

Analyzing the existing literature on SR and immune response as well as on CC and outdoor working activities at risk.

Results

Immune system is crucial to neutralize pathogens, in allergies and autoimmune diseases as well as for cancer control (including skin cancer induced by SR). CC and stratospheric ozone are mutually interacting and the net result is a likely increase in SR exposure. Outdoor workers employed in a number of activities conducted or mainly conducted outdoors are also exposed to a number of risk factors that are modulated by both SR and CC.

Discussion

Risk assessment and management for outdoor workers is of increasing complexity because of a changing climate affecting the exposure to SR and to a number of physical, chemical and biological agents. Individual immune features deserve much more attention in this regard.

Conclusion

Occupational health practices have to take into account the implementation of emerging methodologies (e.g. omics) in exposure assessment, health surveillance and identification of vulnerable subgroups as well as to address emerging issues like those connected to microbiota and occupational health.

Introduction

INAIL Research Centers in Monte Porzio Catone (MPC, Rome) and Lamezia Terme (LT, Catanzaro) are geographically different. An active collaboration was realized with ISAC-CNR-LT. Bridging the competences on occupational health and atmospheric monitoring we realized monitoring campaigns mainly aimed to find interaction between aerobiological, physical, chemical and meteorological parameters.

Methods

Airborne pollen grains were sampled in different areas, indoor and outdoor, using a Hirst-type volumetric sampler and a real-time sampler. The last one is also able to detect other aerobiological particles. Moreover, different meteorological parameters have been measured to evaluate correlation among them.

Results

Samplings were performed both on hourly and daily resolution. Data processing is ongoing and appropriate statistical analyses will be applied. Temperature (sample rate of 1 minutes), relative humidity (with the same rate), precipitation and wind speed will be the main parameters analysed in relation to aerobiological particles. Solar irradiance, ground-level O3, PMx, CO, NOx were also measured.

Discussion

The interactions of organic and inorganic air pollutants with weather parameters may contribute to worsen the respiratory symptoms due to allergy. Previous results of indoor aerobiological monitoring in MPC highlighted the importance of occupants and weather parameters on pollen. Outdoor monitoring extended to meteorological and chemical parameters was conducted in LT associated with real-time aerobiological evaluation.

Conclusion

Targeted monitoring campaigns will be planned in the same periods in MPC, LT and Sapienza University of Rome, representative of suburban, rural and urban areas respectively, aimed at highlighting the role of weather variables and chemical pollutants on aerobiological particles.
O-013 THE EFFECTIVENESS OF SURFACE COATING DISINFECTANT AGAINST ESKAPE ORGANISMS ON VARIOUS SURFACES
Authors: Matuka Dikeledi , Sandhleni Gift , Muleba Lufuno , Jones David , Singh Tanusha
Published: July 2024

Introduction

Disinfectants can reduce microbial contamination of inanimate surfaces, thus minimising the risk of disease transmission. This study assessed the antimicrobial activity and effectiveness of long-lasting surface disinfectants against ESKAPE organisms.

Methods

The surface coating disinfectant (coated once) and 70% ethanol (control) were tested against ~1x106 CFU/ml concentration of ESKAPE bacteria on five different surfaces (stainless steel, wood, glass, plastic, and ceramic tile) for 12 weeks. All organisms were quantified before and after treatment with disinfectants. The effectiveness was calculated using the log and percentage reduction formulae. Microsoft Excel 2016 was used to analyze the data.

Results

Overall, the two disinfectants tested mostly achieved an average ≤ 2 log reduction on all surfaces until week 12, except for a few. SD-ST totally decreased S. aureus on stainless steel within the first four weeks and K. pneumoniae, A. baumannii, and E. aerogenes in week 1, compared to 70% ethanol (week 2 for S. aureus and K. pneumoniae). K. pneumoniae showed a complete reduction on glass, stainless steel, and ceramic tile for SDST and on plastic for 70% ethanol on week 1. Both disinfectants reduced E. faecium by ≤ 2 log reduction except for glass and plastic. Ethanol consistently achieved a 6-log reduction on all surfaces when tested against P. aeruginosa in week 1, whereas SD-ST was only fully effective on wood, glass, and ceramic tile.

Discussion and conclusion

This study found that SD-ST and 70% ethanol did not meet the recommended 99.999% (5 log reduction) for ESKAPE organisms, thus important implications for infection prevention and control.
O-015 PROTECTIVE ROLE OF ANTI-S IGG AGAINST SARS-COV-2 DURING THE OMICRON VARIANT WAVE AMONG HEALTHCARE WORKERS: RESULTS FROM TWO LARGE ITALIAN UNIVERSITY HOSPITALS – ORCHESTRA PROJECT
Authors: Spiteri Gianluca , Monaco Maria Grazia Lourdes , Carta Angela , D’Agostini Marika , Abedini Mahsa , Liviero Filippo , Scapellato Maria Luisa , Porru Stefano
Published: July 2024

Introduction

Vaccination is effective against SARS-CoV-2 infection. However, the role of anti-S IgG (AS) in preventing infection is still unclear. Aim of this study was to understand whether health workers (HW) with high AS titers sustained a lower risk of infection across the Omicron variant (OV) period.

Methods

Within the framework of the ORCHESTRA European project, 3,565 HW from Padova and Verona cohorts, who had at least one AS titration after booster dose, were included. A stratified survival analysis was performed, considering as infected by OV those HW with a positive RT-PCR test between December 2021 and June 2022.

Results

Older age groups (40-49 Hazard Ratio=0.76; CI: 0.64-0.91; p=0.003; 50-59 HR=0.79; CI: 0.67-0.95; p=0.009; >60 HR=0.75; CI: 0.59-0.96, p=0.02) had a lower risk of infection. Previous infected HW had a diminished risk too, although only infections before the first dose reached significance (HR=0.70; CI: 0.54-0.89; p=0.004). The risk reduction was about 18% among HW who had antibody titer above the 80th percentile (HR=0.82; CI 0.71-0.95; p=0.007).

Discussion

Our data showed that older and previously infected HW sustained lower risk of infection during the OV wave. The scant research on AS titer role against OV shows that higher AS levels ensure stronger protection. Our study seems to support these findings. However, this effect is limited and not usable to exclude from further booster doses the HW with high antibody titers.

Conclusion

High AS titer against SARS-CoV-2 showed a protective, albeit mild, role against infection across OV period.
O-017 EXPOSURE RESPONSE RELATIONS BETWEEN BIOAEROSOLS, LUNG FUNCTION WORK-SHIFT CHANGES AND INFLAMMATORY MARKERS: A STUDY OF RECYCLING WORKERS
Authors: Hansen Karoline Kærgaard , Schlünssen Vivi , Broberg Karin , Østergaard Kirsten , Frederiksen Margit , Madsen Anne Mette , Kolstad Henrik
Published: July 2024

Introduction

Domestic waste recycling and subsequent numbers of recycling workers are expected to increase. We aimed to investigate the exposure-response relations between bioaerosol exposures and 1) work-shift change in lung function and 2) inflammatory markers among recycling workers.

Methods

Inhalable dust was measured with personal samplers that were analyzed for endotoxin, bacteria, and fungi. Lung function was measured pre- and post-shift. Inflammatory markers were measured in serum collected post-shift. Exposure-response relations between bioaerosols (inhalable dust, endotoxin, bacteria, and fungi), lung function work-shift changes, and inflammatory markers were explored by linear mixed-effects models.

Results

In total, 101 recycling workers participated with 170 measurements. No associations between bioaerosol exposures and lung function work-shift change were observed. IL2, IL6, IL10, and TNF levels were associated with exposure to inhalable dust, and a 1.40-fold (95% CI: 1.01;1.96) increase in TNF levels by a 10-fold increase to fungi was observed. However, only the association between fungi and TNF was statistically significant.

Discussion

Strengths include the quantitative exposure and outcome data that allowed assessment of exposure-response relations. Limitations include only having one blood sample per worker and, therefore, we cannot assess temporality or change in inflammatory marker levels over time.

Conclusion

This study found no acute lung function change among recycling workers exposed to bioaerosols. Despite the average level of inhalable dust being well below the occupational exposure limit, IL2, IL6, IL10, and TNF levels tended to increase with increasing exposure, indicating an acute inflammatory response at exposure levels currently regarded as safe for workers’ health.

Introduction

During pandemics, vaccination plays a crucial role in mitigating the spread of infection in the workplace. Understanding the factors that influence vaccine acceptance is essential for promoting vaccination. This study aims to assess the acceptance of COVID-19 vaccination and its psychological antecedents among workers in an electricity company.

Methods

We conducted a cross-sectional study among workers in an electricity company, from March to May 2021. We administered a self-administered questionnaire that included sociodemographic and professional data, a 5-item Likert scale to measure vaccine acceptance, and the 5C psychological antecedents to vaccination, covering five domains: confidence, complacency, constraints, calculation, and collective responsibility.

Results

Our study included 146 workers. The median age was 36 years, with 80% being male. Previous COVID-19 infection was reported by 16.4% of participants. When asked about COVID-19 vaccine, 37.7% expressed their acceptance of the vaccine, and 56.6% indicated they would recommend it to others. The majority (86.3%) lacked confidence in COVID-19 vaccines, while 8.2% showed complacency, and 2.7% reported constraints to vaccination. Vaccine acceptance was associated with the levels of confidence (p=0.001), complacency (p=0.006), and constraints (p=0.047). However, there was no significant association between vaccine acceptance and collective responsibility or calculation.

Discussion

The study revealed a low willingness to receive the COVID-19 vaccine among participants. Most participants lacked confidence in the vaccine (86.3%), highlighting the need for trust-building efforts.

Conclusion

To improve vaccine acceptance, tailored strategies are essential. Occupational therapists can play a vital role in promoting vaccination by providing information and raising awareness among workers.

Introduction

Coronavirus COVID-19 pandemic outbreak has contributed to increase work absenteeism associated with sick leave benefits and the measures to mitigate the spread of coronavirus. This study had the objective to verify if the COVID-19 pandemic have impacted in the absenteeism and work-related accidents involving workers of a Brazilian Water/Sewage Company.

Methods

A retrospective and paired cohort study was performed, in which the impact of the COVID-19 pandemic was evaluated in regard to absenteeism management and the number of work-related accidents.The data were analyzed for a period of 12 months from April 2018 until March 2019, before the Coronavirus outbreak, compared with the data collected from April 2020 until March 2021, during the COVID-19 pandemic.

Results

The results showed a 79,6 % increase in the number of absenteeism in 2020-2021 (absenteeism index=5,4) compared to the same period in 2018-2019 (absenteeism index=1.1). The data also revealed a reduction of the total numbers of work-related accidents at 60% during the pandemic. The company had 95 (20%) workers who had tested positive for COVID1-9.

Discussion

In the context of the COVID-19 pandemic, it was shown the impact on absenteeism and work-related accidents in order to secure and maintain the continuity of the essential services, and proper execution of the operations.

Conclusion

It was observed that there was an increase in absenteeism and a reduction in the number of work-related accidents. The pandemic had mostly influenced the work absenteeism and the number of work-related due to the restrictive measures, and also to the elevated number of COVID-19 positive cases.

Authors: Kechkar Hind
Published: July 2024

Introduction

The medical analysis laboratory plays a very important role in the health system because it elaborates the results which can have a critical effect on the patient. The respect of the requirements of health and safety in a medical analysis laboratory ensures the protection of the patients, the staff and the public. The purpose of this study is to determine the risks which can appear in the laboratory and how we can manage these risks.

Methods

To achieve our goal we use AMDEC to determine the risks which can appear with their criticality index. Also we determined all regulatory requirements applicable in a medical analysis laboratory then we determined the average for applying each requirement.

Results

we have found that the disrespect of the hygiene rules can even have an influence on the results of the patient. After implementing the regular requirement of health and safety in chapter IV of the guide to good analysis execution, in Morocco we used for another time the self-assessment as indicator of improvement.

Discussion and conclusion

the implementation of the requirements of the health and safety regulations in medical analysis laboratories conduct to the protection of the patient, the staff and the public. The use of the method AMDEC gives an idea about the risk of non application of the regular requirements and using the self-assessment grid before and after the implementation can determine the improvement reach.

Introduction

Numerous studies have found an association between exposure to ambient air pollution and ischemic heart disease, but only few studies have investigated if occupational exposure to diesel exhaust is associated with cardiovascular disease. The aim of this study was to determine if exposure to diesel exhaust affects the risk of first-time acute myocardial infarction (AMI).

Methods

The study was designed as a register-based follow-up study of the entire Danish working population with estimates on occupational exposure to diesel exhaust based on a quantitative job exposure matrix (1976-2018) and national data on ischemic heart disease throughout the follow-up period (1996-2018). The incidence risk ratio (IRR) for the association between incident AMI and cumulative exposure to diesel exhaust was assessed using Poisson regression with adjustments for demographics, comorbidities, and socio-economic factors as well as other occupational exposures such as noise, physically demanding work, job strain and outdoor air pollution.

Results

In the follow-up period, there were 35,517 cases of fatal and non-fatal first-time AMIs among 903,415 individuals. The IRR for the highest exposed (≥75th percentile) was 1.09 (95%CI:1.05-1.13), whereas the second highest exposed (≥50th percentile) had an IRR of 1.04 (95%CI:1.01-1.08).

Discussion

The results are in accordance with other epidemiological and mechanistic studies of the impact of diesel exposure on cardiovascular disease.

Conclusion

There is an association between cumulative occupational diesel exposure and increased risk of AMI, which should be included in the risk assessment of diesel exhaust.

Authors: Baer Michel , Clement Aude , Ozguler Anna , Loeb Thomas
Published: July 2024

Introduction

Context Workplace cardiac arrest (CA) is often associated with young age, presence of bystanders, quick initiation of cardiopulmonary resuscitation (CPR) and availability of automated external defibrillator (AED). Characteristics and outcome of patients with workplace CA and potential use of an AED were described from the perspective of an emergency medical service.

Methods

The Paris Sudden Death Center is a registry of all CA in Paris region. It was used to include for all patients aged 18 and over with a workplace-acquired CA from 01/04/2014 to 31/12/2022. Data on age, gender, presence of a control, initiation of CPR, use of an AED, duration of no/low-flow, patient outcome, and Cerebral Performance Categories (CPC) score at hospital discharge were collected.

Results

Six hundred and sixty-one patients were included. Most were men (87.9%), with a mean age of 52 (± 12) years. A bystander was often present (79.5%) and performed CPR in 82.7% of cases. AED use was less frequent in 2015 (15%) and peaked in 2020 (50%). Average no-flow and low-flow time were respectively 5.43 min (± 9.84) was 37.8 min (+/-33.9). Fifty-six percent of patients were admitted to hospital, and 40.5% were discharged alive, with a CPC score of 1 in 80.9% and 2 in 15.7% of cases.

Discussion and conclusion

Occurrence of CA in the workplace offers favorable management conditions, resulting in an overall survival rate of 22.7%. Training staff in the use of AEDs, offering first aid training and regular refresher courses are all ways of optimizing the chances of better managing a CA.

Introduction

The requirements and conditions of work in a military environment necessitate a special assessment of fitness for work in active military personnel with cardiovascular diseases.

Objective

The purpose of our study was to assess the impact of cardiovascular disease on fitness for work in active military personnel.

Methods

It is a retrospective descriptive study of active military personnel who consulted for a cardiovascular disease ground at the Military Occupational Health Center between 2019 and 2022.

Results

A total of 39 cases were included in this study with an average age of 45± 8 years and professional seniority of 20± 8 years. They were distributed among non-commissioned officers (64%), enlisted men (20%) and officers (16%). The cardiovascular pathologies identified were chronic venous insufficiency (33%), coronary artery disease (26%), arterial hypertension (13%), cardiac rhythm disorders (8%) and valvulopathy (5%). Exemption from security guards and hard work was indicated in 95% and 46% of cases respectively. Exemption from wearing combat boots and prolonged standing was agreed in 36% and 20% of cases respectively. The average duration of exemption was 5 months ± 2 months. The referral to the reform commission was requested in 10% of cases to determine fitness for military service.

Discussion

The decision on fitness for work in the presence of cardiovascular disease must take account of the various factors involved (physical, mental, environmental, socio-professional,..)

Conclusion

Given the significant impact of cardiovascular disease on work capacity, it is vital to strengthen prevention strategies.

Introduction

Multiple sclerosis (MS)is a chronic inflammatory,demyelinating and degenerative disease of the nervous system.It leads to a progressive loss of neurological function and is the leading cause of chronic neurological disability in young adults resulting in job loss, problems with the employer and co-workers,personal changes in attitudes towards work,and diminished physical capacity.

Aim

Determine the occupational fate of MS patients and factors associated with job retention.

Methods

A cross sectional analytic study which enrolled all cases of MS during the period 2015-2020 selected according to Mc Donald criteria at the neurology department of Sahloul University Hospital and 130 controls matched for age gender and age. Patients enrolled in the study were contacted by phone to answer the questionnaire.

Results

We enrolled 65 MS patients during the study period. The mean age was 38.4 ±6.7 years,a sex ratio of 0.38.The majority of the cases worked in the agriculture sector (23.1%),followed by the health sector (15.4%).The mean length of seniority was 13.8 ±8.5 years at the time of the study,23.7% of patients were unemployed.Job retention was reported in 63.07%of cases and MS was the cause of work stoppage during the first year in 15 cases (23.07%).Job change and accommodation were noted in 6.15% of cases. Return to work was associated with age (p=0.005),income over a thousand dinars(p=0.004),low exposure (p=0.012)and expanded disability status scale(p=0.01).

Discussion and Conclusion

MS has an important occupational impact.Therefore,it seems essential that the management of this chronic disease includes the adaptation of working conditions to the abilities of the patients and an early and multidisciplinary approach.
