Abstract

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; &gt;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.

Published: July 2024

Abstract

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.

Abstract

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.

Abstract

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

Abstract

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.

Abstract

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

Abstract

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.

Abstract

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.

Published: July 2024

Abstract

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.

Published: July 2024

Abstract

Introduction
SARS-CoV-2 infection has been associated with central nervous system involvement, although the impact on the work performance remains largely unknown. Objectives: To investigate cognitive failure, work performance and serum levels of neurofilaments (sNfL) and acid gliofibrillary protein (sGFAP) as biomarkers of neuronal and glial damage, in a cohort of workers with previous SARS-CoV-2 infection.

Methods
The Cognitive Failure Questionnaire (CFQ) and sNfL and sGFAP determination were performed in 150 workers (COVID-19 workers) at the time of negativization after SARS-CoV-2 infection (T0) and after 10 months only in the 50 workers with persistence of symptoms (T1), together with the Work Productivity and Activity Impairment (WPAI) questionnaire. sNfL and sGFAP were also determined in 90 controls with no previous SARS-CoV-2 infection.

Results
sNfL and sGFAP levels at T0 were higher in COVID-19 workers vs controls (median sNfL 22.8 vs 7.2 pg/mL; sGFAP 146.3 vs 63.5 pg/mL; p&lt;0.001 for both). Workers with impaired CFQ at T0 showed higher sNfL and sGFAP levels than those with normal CFQ (median sNfL 45.0 vs 22.4 pg/mL; sGFAP 194.0 vs 131.3 pg/mL; p=0.005 for both). Higher CFQ values were observed at T1 compared to T0 (p&lt;0.01), while sNfL and sGFAP levels were reduced (median sNfL 18.3 pg/mL; median sGFAP 77.2 pg/mL; p&lt;0.001 for both), but always higher than controls. At T1, the 37.5% of workers reported impaired work performance according to WPAI scores.

Discussion and Conclusion
Cognitive failure observed after SARS-CoV-2 infection could be associated with the persistence of neuronal damage and could influence work performance.
P-040 THE RELIABILITY AND VALIDITY OF THE ARABIC-RETURN TO WORK SELF-EFFICACY (RTWSE-19) QUESTIONNAIRE
Authors: Daibes Jumana , Ratzon Navah Z 
Published: July 2024

Abstract

Introduction
The Arabic-Return to Work Self-Efficacy (A-RTWSE-19) questionnaire is a self-report measure intended to assess workers’ beliefs of their current ability to resume regular job responsibilities.

Objective
To translate and assess the reliability and validity of the A-RTWSE-19.

Methods
Ninety participants, 60 (66.7%) healthy, and 30 (33.3%) participants having Hand Injury (HI) with an age range of 18-64 (M=34.5, SD=12.4) were recruited for a cross-sectional study RTWSE-19 was translated into Arabic, and its reliability was tested by Cronbach’s alpha and Intraclass Correlation Coefficient (ICC). Construct validity was tested by comparing working and not working healthy participants.

Results
The Cronbach’s α reliability for all RTWSE-19 items was very high (α =.869). The three scale factors showed high reliability in communication needs (α =.649), modifying tasks (α =.738), and very high reliability in meeting demands (α =.858). The ICC ranged from high in meeting demands (ICC=.790) and modifying tasks (ICC=.769) to very high ICC in communication needs (ICC=.849). The working healthy participants have significantly higher mean than not working healthy participants in all RTWSE-19 scales t(58) =2.60, p=.006, and its factors indicated appropriate construct validity.

Discussion
RTWSE-19 can be used to identify individuals needing additional support or interventions to improve their self-efficacy and their chances of successfully returning to work.

Conclusion
The A- RTWSE-19 is a reliable and valid questionnaire for assessing the workers’ beliefs of their current ability to resume regular job responsibilities among Palestinian HI patients.

Published: July 2024

Abstract

Introduction and Objective
to assess the work-related damages in frontline health care professionals to cases of COVID-19 in the initial phase of the pandemic period.

Method
analytical cross-sectional study, with health professionals, at all levels of care in the national territory. Data collection carried out between April and June 2020, through a sociodemographic and labor characterization questionnaire; the Job Stress Scale and the Work-Related Harm Assessment Scale. A multinomial logistic regression was built to analyze the factors associated with global damage.

Results
among 437 participants, the highest average of damages was for the physical dimension. Moderate global harm was associated with: nursing technician/auxiliary, weekly shift of 60 hours or more, and psychosocial condition of active or high-strain work. High global harm was associated with: age up to 45 years, having a morbidity, nursing technician/assistant, and psychosocial condition of active or passive or high-strain work. Low social support at work increased the chance of moderate and high harm.

Discussion and Conclusion
in the COVID-19 pandemic scenario, a profile of workers was observed who deserve special attention in work-related risk and disease prevention programs
