The objective of this study is to investigate factors influencing the time to return to work (RTW) of HealthCare Workers (HCW) infected with COVID-19 during the initial wave of the pandemic in a southern French university hospital. Data collection of 170 HCW (between March 16 to June 1, 2020) included demographic and professional information, clinical profiles, comorbidities, medical management, therapies and RT-PCR results. The mean time to RTW was 15.6 days. Multivariate analyses revealed that the time to RTW was shorter among laboratory and emergency workers, while it was longer for HCW aged 40 to 49 years, at higher risk of severe illness, with a delayed negative SARS-CoV-2 PCR or those treated with azithromycin and/or hydroxychloroquine. This study highlights diverse factors affecting HCW RTW post-COVID-19 infection, underscoring the importance of exercising caution in administering unproven therapies to HCW during the early stages of a novel infectious pandemic.

The World Trade Center (WTC) Health Program is a limited federal health care program that provides medical monitoring and treatment for WTC-related health conditions to responders and survivors impacted by the terrorist attacks on September 11, 2001.This study described the characteristics of the Program survivor members (who lived, worked, went to school, daycare or adult daycare or present in the New York City Disaster Area of 9/11/2001) to stimulate innovative ideas for improving healthcare services, generate new research interest, and serve as a reference for future research on this population. Administrative and medical claims data collected from the Program start date (07/01/2011) through 2022 were used. As of 12/31/2022, there were 37,384 enrolled survivors: 5.0% were aged ≤21 years on 9/11/2001, 45.9% females, and 31.2% non-Hispanic Whites. A total of 24,148 (64.6%) were certified for at least one WTC-related condition, including neoplasms (36.0%), aerodigestive disorders (35.6%) and mental health conditions (18.6%); 22.9% were certified for more than one category. Certification rates of some WTC-related conditions differed by sex, age and race/ethnicity. WTC survivor population is diverse in sex, age and race/ethnicity, with a high proportion certified for certain WTC-related health conditions, providing great opportunities for research in various areas.

This study aimed to identify characteristics of workers experiencing health problems without a decline in labor productivity to address presenteeism. A cross-sectional analysis was conducted on 554 workers in Japan, with a median age of 43 years. Participants reported any health problems in the past month, along with job stressors, stress responses, social support, and job and life satisfaction using the Brief Job Stress Questionnaire. They were categorized into three groups: "no symptoms," "pre-presenteeism" (health problems without work impact), and "presenteeism" (health problems with work impact). Results showed that 30.1% were in "prepresenteeism" and 52.0% in "presenteeism." Stress responses and social support were linked to both "pre-presenteeism" and "presenteeism," while job stressors and job and life satisfaction were only associated with "presenteeism." These findings offer insights for preventing presenteeism.

B A rapid review was conducted to describe pesticide exposure assessment methodologies in Agricultural Work Contexts (AWC)s in Latin America and the Caribbean (LAC), in order to provide elements to reduce vulnerabilities within the agricultural population. A final number of 79 articles were selected from Medline via Pubmed, LILACS, and SciELO. In the region, family agriculture is the predominant form of agricultural production (72%) in informal agricultural work contexts (AWCs), which are characterized by small-scale diversified agricultural production, lower educational attainment, limited income, and a lack of social and healthcare security for the families. Indirect exposure assessment methods were the most commonly reported (58%), and its use was associated with informal AWCs (p = 0.011). Understanding AWCs and employing appropriate assessment methods can contribute to addressing vulnerabilities in the agricultural sector.

This study aimed to identify the perceived advantages and drawbacks of teleworking and their correlates, including health problems, among Lebanese workers holding a university degree. A web-based cross-sectional self-report questionnaire created on Google Forms was used to survey 230 participants through snowball sampling between October 2022 and March 2023. The majority of respondents recognized both the advantages (67.03%) and drawbacks (66.34%) associated with teleworking, suggesting mixed feelings toward this format. Despite the limited satisfaction with teleworking, respondents acknowledged the advantages associated with remote working; in particular, younger, less physically active, and more educated participants valued teleworking more than their counterparts. The mean perception of advantages and drawbacks of telework did not significantly change with participants' work status (hybrid, online, and in-person). The study revealed a high prevalence of consistent sleeping difficulty (35.7%), limited regular physical activity (60.4%), work-related musculoskeletal disorders (48.7%), back pain (5.7%), and visual disorders (48%) among Lebanese workers. Despite the limited satisfaction with teleworking, respondents acknowledged advantages such as cost and time savings. Older workers showed a preference against teleworking, potentially due to its impact on well-being. Factors such as education, career satisfaction, and prior teleworking experience influenced individuals' perceptions of telework benefits.

Chlorpyrifos (CPF) is a widely used organophosphate insecticide that has been linked to detrimental health effects that range from neurological impacts to respiratory disease. The objective of this study was to assess respiratory symptoms associated with CPF exposure throughout the application season. Urine samples were collected from Egyptian adolescent applicators (n = 206) and non-applicators (n = 72) to assess 3,5,6-trichloro-2-pyridinol (TCPy), a biomarker for CPF exposure, along with spirometry measures to determine lung ventilatory function. Samples were collected over 7 months in 2016. Logistic regression was used to model the odds of reporting wheeze symptoms based on urinary TCPy concentrations while controlling for age and smoking in the household. Ordinal multinomial logistic regression was used to model the percent reference for forced expiratory volume in one second (rFEV₁) based on urinary TCPy concentration (µg/g creatinine). Wheezing increased with increasing pesticide exposure (OR = 1.74 (1.32 - 2.31)). There was no statistically significant relationship between rFEV₁ and TCPy concentration. Efforts to reduce pesticide exposure should be implemented to prevent the potential onset or exacerbation of any linked respiratory complications in adolescents.

This study examines the associations between working night shifts and various outcomes, including sleep patterns, healthcare workers' sleep quality, and physical, mental, and social well-being. A descriptive cross-sectional study was conducted, where the findings revealed that night shift healthcare workers experienced poor sleep quality and pattern. In addition, night shift healthcare workers were more likely to express their intent to leave, the impact of work on their social lives, and a low level of job satisfaction. Healthcare workers showed moderate anxiety and mild depression levels. Lower job satisfaction correlated with higher anxiety and depression levels among healthcare workers, while the negative impact of working hours on social life was associated with increased anxiety and depression. Organizations should consider establishing comprehensive wellness initiatives covering work-life balance, stress management strategies, and mental health resources.

This study aimed to explore the prevalence of work-related musculoskeletal disorders (WMSDs) and to investigate factors associated with WMSDs in commercial motorcyclists in Indonesia. This cross-sectional study involved commercial motorcyclists operating in Indonesia. Data were collected using an anonymous questionnaire, including the Indonesian Version of the Nordic Musculoskeletal Questionnaire, occupational driving posture questionnaire, and occupational factor-related questions. The questionnaire was distributed at four rest stops located in Central Jakarta, Indonesia. The result showed that 40% of participants (129/322) were having WMSDs. Older age, overweight body mass index (BMI), obese body mass index, nonregular physical activity, driving duration (> 8 h/day), seniority (≥5 years), and poor driving posture were significant risk factors for WMSDs in commercial motorcyclists. Based on the risk factors identified in this study, the development of preventive strategies among commercial motorcyclists is warranted.

This study investigates the impact of micro-environmental factors on worker breathing zone exposure levels in petrochemical facilities. A laboratory simulation study evaluated near-field exposure to methane for a typical maintenance task. Individual and combinations of micro-environmental factors significantly affected methane exposure. Airflow direction and speed were significant determinants of exposure concentration reduction. A side airflow direction at medium to high speed produced the lowest gas concentration in the breathing zone. Worker body orientation relative to the methane emission point was also a critical factor affecting gas concentration in the worker's breathing zone. The study provides insights into how variations in airflow and small changes in position impact near-field exposures for petrochemical tasks, guiding industrial hygiene professionals' training on qualitative exposure estimation and providing input for near-field exposure modeling to guide quantitative exposure and risk assessment.

This descriptive study was conducted to compare the job demands, job control, social support and mental health status of thermal power plant and underground coal mine workers. 158 workers in thermal power plant and 162 workers in underground coal mine participated in the study. The results unearthed that thermal power plant workers had 2.3 times better mental health (p < 0.001 OR = 2.3 CI = 1.50-3.74) and 3.0 times lower job demands (p < 0.001 OR = 3.0 CI = 1.91-4.92) than coal mine workers. In the study, it was determined that mental health was positively affected as job control and social support increased in both thermal power plant and underground mine workers (p < 0.05); there was no significant relationship between job demands and mental health (p > 0.05). These results indicate that underground mine workers are at higher risk in terms of mental health and job demands than thermal power plant workers.
