Combined therapy with pirfenidone and nintedanib counteracts fibrotic silicosis in mice.

Pneumoconiosis, especially silicosis, is a prevalent occupational disease with substantial global economic implications and lacks a definitive cure. Both pneumoconiosis and idiopathic pulmonary fibrosis (IPF) are interstitial lung diseases, which share many common physiological characteristics. Because pirfenidone and nintedanib are approved to treat IPF, their potential efficacy as antifibrotic agents in advanced silicosis deserves further exploration. Thus, we aimed to evaluate the individual and combined effects of pirfenidone and nintedanib in treating advanced silicosis mice and elucidate the underlying mechanisms of their therapeutic actions via multiomics. We administered monotherapy or combined therapy of pirfenidone and nintedanib, with low and high doses, in silicosis established after 6weeks and evaluated lung function, inflammatory responses and fibrotic status. Additionally, we employed transcriptomic and metabolomic analyses to uncover the mechanisms underlying different therapeutic strategies. Both pirfenidone and nintedanib were effective in treating advanced silicosis, with superior outcomes observed in combination therapy. Transcriptomic and metabolomic analyses revealed that pirfenidone and nintedanib primarily exerted their therapeutic effects by modulating immune responses, signalling cascades and metabolic processes involving lipids, nucleotides and carbohydrates. Furthermore, we experimentally validated both monotherapy and combined therapy yielded therapeutic benefits through two common signalling pathways: steroid biosynthesis and purine metabolism. In conclusion, pirfenidone and nintedanib, either individually or in combination, demonstrate substantial potential in advanced silicosis. Furthermore, combined therapy outperformed monotherapy, even at low doses. These therapeutic benefits are attributed to their influence on diverse signalling pathways and metabolic processes.

Musculoskeletal Disorders and Related Risk Factors in Iranian Military Personnel: A Systematic Review and Meta-Analysis

Background: Work-Related Musculoskeletal Disorders (WRMSDs) are prevalent and costly diseases in military occupations. WRMSDs are prevalent and costly diseases in military occupations. We investigated the exposure to ergonomic risk factors and the prevalence of musculoskeletal disorders (MSDs) among military personnel in the workplace. Method: We aimed to investigate MSDs by conducting electronic searches on Persian databases such as SID, MagIran, and IranMedex, and English databases like PubMed, Web of Sciences, and Scopus. The search was not restricted by time and was conducted until Dec 20, 2021. Two researchers independently extracted the data, and the quality of the research was evaluated using the STROBE checklist. The results of different studies were merged and incorporated into the analysis using Comprehensive Meta-Analysis (CMA) v3 software. Results: Eleven qualitative studies found that 92% of the respondents were men (83% to 96%). The mean age was 34.17 ± 0.16 yr, with a confidence interval (of 95% CI:33.85-34.48). The mean BMI was 25±0.39 with a confidence interval of 95% CI:24.28-25.84. The mean work record was 12.89±0.81 yr with a confidence interval of 95% CI:11.30-11.48. The highest outbreak of MSDs is in the knee at 38.1% (95%CI:32.1-44.4), 37.6% of the neck (95% CI:24.8-52.5), and 32.5% of the shoulder. (95%CI:22.5-44.3) was observed. Conclusion: The wide role of various dimensions of work tasks and repetitive tasks (such as lifting, moving or changing positions, standing for long periods, as well as improper postures) in causing WRMSDs. Additionally, the risk factor in the workplace has financial implications for the military organization. The reduction of physical and psychological demands, as well as the improvement of ergonomic standards in the workplace, should be addressed to decrease MSDs in military centers.

Temporal Trends of Early COVID-19 Infections in New York City Transit Workers and Residents: March 01, 2020-May 02, 2020.

The continuity of public transportation was necessary during the COVID-19 pandemic so that essential workers could report for duty. Therefore, it is important to consider COVID-19's impact on transit workers themselves. We described COVID-19 incidence rates over time in New York City (NYC) transit workers and the NYC general population during March-May, 2020. NYC transit COVID-19 cases were abstracted from occupational injury and illness logs, and health department data was used to ascertain NYC resident cases. COVID-19 rates among transit workers peaked during the week of March 22-28 (429.8 cases/100,000 workers). The peak in transit workers occurred 1-2weeks before the general public's peak (March 29-April 4: 368.8 cases/100,000 people; April 5-11: 357.8 cases/100,000 people). These data suggest that NYC transit workers may have been impacted by COVID-19 earlier than the general public. Thus, improving early detection and response of respiratory disease outbreaks may be vital to protecting transit workers.

Endothelial dysfunction in combination of occupational pathology of the respiratory system and atherosclerosis in coal industry workers

Introduction. The increasing prevalence of cardiovascular pathology among industrial workers determines the importance of studying not only occupational diseases, but also their combination with diseases of the circulatory system. Endothelial dysfunction is a key link in the pathogenesis of atherosclerosis. Evaluation of endothelial function indicators in occupational respiratory diseases in combination with atherosclerosis in workers of the coal mining industry is an urgent task. The study aims to consider the indicators of endothelial function in miners with occupational respiratory diseases in combination with atherosclerosis. Materials and methods. The authors have examined 88 miners with previously diagnosed occupational respiratory diseases (chronic dust bronchitis, anthracosilicosis, chronic obstructive pulmonary disease), 45 of them showed signs of atherosclerosis. There were two comparison groups without signs of atherosclerosis: 44 miners who work long-term in harmful working conditions, without lung pathology (control group) and 42 residents of Novokuznetsk who have never worked in harmful working conditions, and without lung pathology (unexposed group). Results. We found that miners with occupational respiratory diseases in combination with atherosclerosis had several forms of endothelial dysfunction: vasomotor (decreased synthesis of nitric oxide, increased endothelin-1 levels), hemostatic (increased levels of Willebrand factor), adhesive (increased levels of endothelial adhesion molecules sVCAM-1). The development of respiratory insufficiency in miners with occupational respiratory diseases increases endothelial dysfunction: miners with respiratory insufficiency have lower levels of nitric oxide (NO), higher levels of endothelin-1 and endothelial adhesion molecules sVCAM-1 than miners without respiratory insufficiency. There are correlations between indicators of endothelial function and production factors: with work experience in harmful working conditions, the level of the average concentration of coal-rock dust in the workplace and the frequency of exceeding the maximum permissible concentration of coal-rock dust. Limitations. The study is limited to a sample of workers in the main professions of coal mines who were examined at the Research Institute of Complex Hygiene Problems and Occupational Diseases, aged 40 to 54 years, with more than 15 years of experience working in underground dust conditions. Conclusion. Miners with occupational respiratory diseases in combination with atherosclerosis develop several forms of endothelial dysfunction: vasomotor, hemostatic, adhesive. The development of respiratory failure increases endothelial dysfunction. Ethics. This medical study involving a human as a subject was carried out in compliance with the Ethical principles presented in the latest version of the Helsinki Declaration, developed by the World Medical Association.

Changes in heart rate variability and subclinical heart failure with preserved left ventricular ejection fraction in workers of the main professions at the coal industry

Introduction. The high prevalence of diseases of the circulatory system necessitates their detection and prevention at an early stage, especially in regions with high industrial potential. The occurrence of subclinical heart failure depends on a cascade of processes that are already occurring in the body and may eventually manifest themselves in clinically pronounced diseases. One of the possible mechanisms of its development is a violation of the balance of the autonomic nervous system with a violation of adaptive capabilities to the labour process, characterized by severe physical overloads among miners. The study aims to evaluate changes in heart rate variability in workers of the main professions at the coal industry with signs of heart failure with a preserved left ventricular ejection fraction. Materials and methods. The study included 78 employees of the main professions at the coal industry. Specialists performed ultrasound examination of the heart according to generally accepted methods with the study of longitudinal deformation of the myocardium. The concentration of NT-proBNP in the blood serum was determined by solid-phase enzyme immunoassay. The authors also conducted an analysis of heart rate variability, determined temporal, spectral and linear parameters. Results. Specialists revealed a decrease in longitudinal myocardial deformation in 38.5% of the examined patients, signs of diastolic dysfunction in 41%; in these groups, a tendency to increase the concentration of NT-proBNP was revealed. In the examined miners with heart failure with preserved ejection fraction, they revealed a significant decrease in the SDNN index and an increase in IC values. The increase in DFA and LF/HF indicators reflects a vegetative imbalance towards sympathetic activation observed in all surveyed miners. Limitations. This study is limited to a sample of employees of the main professions of the coal industry undergoing periodic medical examination at the Research Institute of Complex Problems of Hygiene and Occupational Diseases. Conclusion. The revealed relationship between indicators of heart failure and heart rate variability (SDNN, LF/HF, DFA and IC) in miners allows us to identify a group of people at greatest risk of adverse outcomes. Ethics. The study was conducted in compliance with the standards of the Bioethical Committee of the Research Institute of Complex Problems of Hygiene and Occupational Diseases, established in accordance with the Helsinki Declaration of the World Medical Association "Ethical Principles of Conducting medical Research with human participation as a subject" as amended in 2013 and the "Rules of Good Clinical Practice" approved by Order No. 200n of the Ministry of Health of the Russian Federation dated 04/01/2016. The subjects signed an informed consent to participate in the study.

Assessment of age-related features of the condition of heavy-duty truck drivers based on spectral analysis of EEG-ECG and stress tests during mass occupational examinations

The authors studied the physiological characteristics of drivers of heavy-duty coal mine vehicles based on spectral analysis of EEG-ECG and stress tests, which have prognostic value in professional activity. The study aims to assess the functional condition of heavy-duty truck drivers of different age groups based on a comprehensive spectral analysis of EEG-ECG under occupational examinations. During the survey, the authors have studied the spectral parameters of the EEG‒ECG in 300 male drivers aged 25 to 66 years. Specialists have performed EEG registration when placing electrodes in the 10–20 system. The EEG analysis was performed with a preliminary visual analysis followed by the removal of artifacts. The scientists assessed the level of representation of the main alpha rhythm and its spatial distribution. The ECG registration was in the first lead. The duration of EEG-ECG registration is about 15 minutes in a typical sequence of stress tests: baseline, rhythmic photostimulation, hyperventilation with recovery periods. The spectral analysis of the EEG‒ECG was performed automatically on a Neurotravel device (Italy). The authors found lower alpha and delta activity in the initial EEG spectra in older drivers aged 45–66 years, which contributed to the cumulative effect of stress load. Light stress stimulation significantly reduced alpha and delta activity and increased beta EEG activity in both groups, while in the older group the high-frequency range significantly exceeded the low-frequency range. Simultaneously with the changes in the EEG, stress photostimulation increased the energy of the ECG spectra in all frequency ranges. The authors established the appearance of additional stress indicators during light stimulation in older drivers based on the correlation of EEG‒ECG spectra (alpha/delta) and the absence of such changes in the group of young drivers aged 25–35 years. Moreover, the EEG–ECG correlation coefficients and their critical values increased in groups in increments of 6 years — from 35 to 65 years. Elderly drivers, based on neuro-cardiodynamic indicators, were in a state of chronic stress and the resulting risks to health and professional activity, and the identified physiological mechanisms of stress may be at the heart of ways to prevent it. Limitations. The study is limited to the assessment of EEG and ECG indicators in 300 heavy truck drivers. Ethics. The study was performed using non-invasive methods and approved by the Bioethical Committee of the Research Institute of Complex Problems of Hygiene and Occupational Diseases, Protocol No. 5, § 1 dated 12/26/2018, in accordance with the Helsinki Declaration of the World Medical Association "Ethical Principles of conducting medical research with human participation as a subject" as amended in 2013 and the "Rules of Good Clinical Practice" approved by by Order of the Ministry of Health of the Russian Federation No. 200n dated April 1, 2016. All the examined patients signed a voluntary informed consent to participate in the study.

Radiofrequency ablation guided by real-time cardiovascular magnetic resonance.

Cardiovascular magnetic resonance (CMR) is gaining ground in guiding electrophysiology (EP)-based ablation procedures of typical atrial flutter and atrial fibrillation, allowing for the avoidance of radiation exposure for patients and operators and reducing the risk of occupational illnesses. CMR allows comprehensive assessment of cardiac anatomy and provides tissue characterization by identifying pathological substrates, such as myocardial scars and edema, identified with the implementation of late gadolinium enhancement and T2-weighted short-tau inversion recovery sequences. Intraprocedural imaging is useful for real-time catheter tracking during the ablation procedure while simultaneously providing visualization of cardiac anatomy. Additionally, CMR facilitates the evaluation of the ablation procedure accuracy by acquiring edema-sensitive sequences, thereby aiding in preventing early complications. This report serves as a primer for radiologists and illustrates the value of CMR in planning and performing the ablation procedure, as well as its role in post-procedural imaging.

Impact of extreme bushfire seasons on rates of occupational injury and disease compensation claims in first responders.

This study aimed to use workers' compensation (WC) data to explore the impact of the extreme bushfires on injury/disease claim rates amongst first responders (FR) compared with other occupations and off-seasons. Data on WC claims for FR (ambulance officers, paramedics, firefighters, police) and other occupations were obtained from WorkSafe Victoria 2005-2022. Negative binomial regression models adjusting for age, gender and number of employed people were used to estimate incident rate ratios of all injury/disease, mental, musculoskeletal and respiratory claims among FR in summer and extreme bushfires compared to off-season/summer and other occupations. There were 120,022 claims in 2005-2022; 54% were musculoskeletal injuries. Claims rates were significantly higher for all injuries/diseases, mental, musculoskeletal and respiratory conditions in FR than other occupations across off-season, summers and extreme bushfires. FR were 1.5-3.9 times more likely to claim for mental health conditions during extreme bushfires than off-season compared with other occupations. Firefighters were at increased risk of all injury/disease and mental and musculoskeletal injury claims during summer and extreme bushfires than off-seasons. Ambulance officers and paramedics had the highest claim rates, particularly in off-seasons, with a higher risk of all injury/disease and mental claims in extreme bushfires than in summers. Respiratory and mental claims were increased amongst police and other occupations during extreme bushfires. Extreme bushfire events were associated with increased mental claims rates in all FR, with the highest in firefighters. Strategies to better prevent and manage injury/disease risk in FR are urgently required, particularly for mental health conditions.

ANÁLISE DE RISCOS NA PRODUÇÃO DE FRIGORÍFICOS: ESTRATÉGIAS PARA PREVENÇÃO E CONTROLE

This paper is a scientific article whose theme is the analysis of risks in the production of meatpacking plants: strategies for prevention and control. In this environment, workers face physical risks, biological risks and risks of accidents. This is because, in meatpacking plants, we find places where the temperature is extremely low (usually below 0º). Therefore, the function of the PPE provided is to provide safety to avoid humidity, low temperatures, noise, injuries caused by sharp instruments and biological contamination. What strategies should be adopted to prevent and control the occurrence of accidents and/or the spread of diseases in the production line of meatpacking plants, based on risk analysis? The general objective is: to describe what risk management is as well as the best way to apply it in a meatpacking plant to prevent accidents and control occupational diseases. The specific objectives are: to characterize what risk analysis and management are in a meatpacking plant; to present the main characteristics of the production environment as well as the main precautions that should be taken to ensure the physical integrity of the worker; describe the guidelines set out in NR-32 and its determinations for occupational health and safety, especially in companies that work with the slaughter and processing of meat and meat products. The methodology used will be a descriptive and exploratory literature review

Textile Fabric Defect Detection Using Enhanced Deep Convolutional Neural Network with Safe Human–Robot Collaborative Interaction

The emergence of modern robotic technology and artificial intelligence (AI) enables a transformation in the textile sector. Manual fabric defect inspection is time-consuming, error-prone, and labor-intensive. This offers a great possibility for applying more AI-trained automated processes with safe human–robot interaction (HRI) to reduce risks of work accidents and occupational illnesses and enhance the environmental sustainability of the processes. In this experimental study, we developed, implemented, and tested a novel algorithm that detects fabric defects by utilizing enhanced deep convolutional neural networks (DCNNs). The proposed method integrates advanced DCNN architectures to automatically classify and detect 13 different types of fabric defects, such as double-ends, holes, broken ends, etc., ensuring high accuracy and efficiency in the inspection process. The dataset is created through augmentation techniques and a model is fine-tuned on a large dataset of annotated images using transfer learning approaches. The experiment was performed using an anthropomorphic robot that was programmed to move above the fabric. The camera attached to the robot detected defects in the fabric and triggered an alarm. A photoelectric sensor was installed on the conveyor belt and linked to the robot to notify it about an impending fabric. The CNN model architecture was enhanced to increase performance. Experimental findings show that the presented system can detect fabric defects with a 97.49% mean Average Precision (mAP).

Evaluation of the implementation of SMK3 at the Grandmed Lubuk Pakam Hospital in 2024

SMK3 has been regulated in the guidelines for occupational safety and health in hospitals, but its implementation may face various challenges. Various factors such as the dynamics of the work environment, regulatory changes, and aspects of organizational culture can affect the effectiveness of SMK3 implementation. Permenkes No.66 of 2016 Article 4 states that SMK3 Hospitals include the determination of K3RS policies, K3RS planning, implementation of K3RS plans, monitoring and evaluation of K3RS, review and improvement of K3RS. This qualitative study aims to evaluate the implementation of SMK3 at Grandmed Lubuk Pakam Hospital. The informants were 5 people by conducting in-depth interviews equipped with a voice recorder. The research variables are K3RS policies, facilities and infrastructure, and human resources. The results of the study are that Grandmed Hospital has implemented the K3RS policy by having a commitment to implementing K3, but in its application to workers it has not been implemented properly, establishing a K3RS organization that plays a role in minimizing the risk of accidents and occupational diseases, providing complete K3 facilities and infrastructure in accordance with SOP, and only having one human resource expert as K3 personnel at the hospital. The suggestion given is that Grandmed Hospital Lubuk Pakam is expected to be able to improve professional human resources in the field of K3RS not only General K3, can build awareness of the importance of K3 through regular communication campaigns, plan monthly activity agendas such as role plays on the importance of K3 culture. Keywords: SMK3; K3RS Policy; Facilities and infrastructure; Human resources.

What are the regulations governing physicians in Germany and Austria? What happens if suspected cases occur in different EU countries? European regulations govern cooperation between social insurance institutions and regulate the obligations of medical professionals in reporting occupational diseases.

Recommendations for patch testing with patient’s own materials in occupational dermatology

AbstractAllergic contact dermatitis is one of the most common occupational skin diseases. Due to the limited availability of commercial patch test preparations, patch testing patient’s own material (POM) is of great importance in the diagnosis of occupational contact dermatitis. In a research project (FB 317b) funded by the German Social Accident Insurance (DGUV), a comprehensive assessment of the quality of patch testing with POM in individuals with suspected occupational skin diseases was carried out for the first time in Germany. The initial results show considerable deficiencies in the documentation and in some cases also in the performance of patch testing POMs. Therefore, recommendations for patch testing POM and in particular patch testing with workplace materials are presented.

Plasma Brain-Derived Neurotrophic Factor (BDNF) Levels and BDNF Promoters’ DNA Methylation in Workers Exposed to Occupational Stress and Suffering from Psychiatric Disorders

Introduction: Decreased plasma BDNF (pBDNF) levels have been proposed as a biomarker in the illness phases of mood disorders. This cross-sectional study aimed to evaluate the pBDNF and BDNF promoters’ DNA methylation levels in workers exposed to occupational stress and suffering from work-related stress disorders. Methods: the pBDNF and BDNF exon I and IV promoters’ methylation levels were measured by specific immunoassays and methylation-sensitive high-resolution melting (MS-HRM) in 62 patients with adjustment disorders (AD), 79 patients with major depressive disorder (MDD) and 44 healthy controls. Occupational stress was evaluated in the patients and controls using the Job Content Questionnaire (JCQ). Results: the pBDNF levels were significantly higher in the MDD (p < 0.001) and AD (p < 0.0001) patients than in the controls. The MDD patients showed significantly lower pBDNF levels than the AD ones (p = 0.01). The BDNF exon I and IV promoters’ methylation levels were significantly higher in the MDD patients than in the AD ones (exon I promoter: p = 0.0001, exon IV promoter: p < 0.0001) and controls (exon I promoter: p = 0.0001, exon IV promoter: p < 0.0001). In the patients, but not in the controls, the BDNF promoters’ methylation levels showed significant negative correlations with occupational stress. Conclusions: BDNF could play a key role in the pathophysiology of stress-related disorders and the peripheral elevation of it observed in patients exposed to occupational stress could suggest a protective mechanism for neurons from stress-mediated damage. The elevation of the pBDNF levels, even in MDD, may characterize a “reactive” subtype of depressive episode, while the significant elevation of the BDNF promoters’ methylation levels in depressed patients could indicate a predisposition to more severe illness under stress. Further research is needed, focusing on biomarkers for stress-related disorders as a potential tool for the diagnosis and prevention of occupational diseases.

Strategic Directions for Strengthening Sustainability of Forestry Workforce

Today in many countries and regions, forestry sector deals with a considerable shortage of forestry workers and faces the serious challenge of ensuring a qualified and sustainable workforce. Current global processes and structural changes, such as emigration from rural areas, aging of the population, unfavorable age structure of existing employees, negative demographic trends (migrations, decline in birth rate, negative natural increase, etc.), lack of interest in the so-called 3D (dirty, dangerous and demeaning) jobs, low cost of labor and others, significantly contribute to such an adverse situation. Additionally, forestry work, especially wood harvesting, represents a very risky, professionally highly demanding and physically extremely intensive activity, which is regularly classified as one of the most dangerous occupations with a high proportion of serious injuries, fatalities and occupational diseases. For these reasons, the forestry profession is considered unattractive, and the job of a forestry worker undesirable. All of this makes finding the people interested in these jobs very difficult, and the task of ensuring the necessary workforce for all regular activities in sustainable forest management becomes very hard. In this paper, based on the surveys carried out in the Federation of Bosnia and Herzegovina (FB&H), i.e. evaluation of forestry workforce sustainability factors, and on the study of available strategic documents, policies and case studies, strategic directions aimed at strengthening the sustainability of forestry workforce were elaborated. The sustainability factors were observed in three categories related to: a) stronger recruiting in forestry, b) more successful retention of forestry workers, and c) higher work commitment of forestry workers. Established rankings, together with other findings, were used to define four separate strategic directions: (1) Direct financial strategy, which emphasizes direct monetary payments to workers and is oriented towards labor productivity, (2) Indirect financial strategy, which focuses more on providing indirect material gains to workers and the quality of performed work, (3) Educational strategy, aimed at the education and training of workers, and (4) Technical-technological strategy, aimed at increasing the mechanization in forest operations thus reducing the demand for labor. The paper elaborates the basic starting points and main characteristics (priorities, measures and activities, stakeholders, responsible authorities, etc.) of each strategic direction considering the possibility and conditions of their implementation in national forestry sector. The objective of the paper is to raise the required awareness of the forestry workforce issues, its position and status, and also to provide foundations for enhancing the attractiveness of forestry work and improving the overall sustainability of the forestry workforce. The results of the study point out the critical issues and provide valuable insights that can help in formulating effective policies and strategies for the future.

Enhancing Health Literacy Among Disadvantaged Youth: A Participatory Approach in School Settings

Abstract Background School-based health literacy interventions have the potential to significantly impact the health of disadvantaged youth. However, the effectiveness of such interventions varies. The aim of the ‘health literacy among youth’-intervention was to improve the health literacy of disadvantaged youth in two school settings in Denmark. Methods The intervention began with identifying the health literacy needs of 128 students. Groups of teachers from each school participated in workshops facilitated by the research team to develop activities to address the specific needs of the students. Over the course of one school year (August 2023 to May 2024), these activities were implemented. Questionnaires were administered to students before, during, and after the intervention, and semi-structured interviews were conducted among teachers and students. Results Teachers at each school created activities aligned with the organizational structure and the needs of the students, focusing on occupational diseases and injuries, and physical activity and mental well-being, respectively. However, contextual factors such as time constraints, students’ characteristics, and teachers’ professional backgrounds and varying levels of motivation, influenced the implementation. Conclusions The intervention design offered flexibility in tailoring health literacy activities and their implementation to suit the unique contexts of the two schools. While the participatory approach facilitated targeted and organizationally aligned health interventions, its feasibility varied across contexts. Our findings highlight the importance of involving participants in developing health interventions to ensure relevance and alignment with specific needs of the target group. Key messages • Despite contextual similarities, the outcome of participatory intervention approaches may vary across contexts. • Co-creation contribute to health literacy interventions that are tailored the needs of the target group.

Health impact of the Serious Accidents Punishment Act in Korean occupational settings

Abstract Background Interrupted time series analysis serves as a valuable study design for assessing the efficacy of public health interventions implemented at a specific moment in time at the population level. We aim to elucidate the effects of the Serious Accidents Punishment Act implemented in February 2021 in Korea by analyzing changes in the incidence rates of occupational diseases. Methods The monthly data from patients with occupational diseases was extracted from the National Health Insurance Service Cohort database from 2011 to 2023. An Interrupted time series analysis with Poisson segmented regression was used to compare the rates before and after the Serious Accidents Punishment Act introduction in both outpatients and inpatients. Adjustments or stratification variables included sex, age, company size, and injury-related international classification of diseases codes (Injury, poisoning, and certain other consequences of external causes, S00-T88). Results Based on injury rates, men’s inpatient injury rates remained stable, but outpatient rates decreased after the act implementation, while women’s injury rates consistently declined in both inpatient and outpatient settings. The Interrupted time series regression analysis indicates that the Serious Accidents Punishment Act led to a significant reduction in both outpatient and inpatient injury rates for men and women, with a marked decline in outpatient rates and hospital admissions among women post-intervention. Conclusions The Interrupted time series regression results suggest that the Serious Accidents Punishment Act has been effective in reducing injury-related healthcare usage, highlighting the necessity of gender-specific interventions and the potential impact on lowering inpatient visits, although causality remains uncertain without further analysis. Key messages • The Serious Accidents Punishment Act significantly reduced occupational injury rates in Korea, especially among women, demonstrating effective public health intervention. • Interrupted time series analysis reveals Serious Accidents Punishment Act’s impact on reducing healthcare usage for occupational injuries, highlighting the need for gender-specific approaches.

The Impact of a 12-Week Workplace Physical Activity Program on the Quality of Life of Sedentary Workers: A Pilot Study

Office workers frequently display behavioral patterns marked by extended periods of sedentary and seated work. In this context, the implementation of a workplace exercise program has been shown to be effective in mitigating health-related risk factors. This study aimed to evaluate the impact of a 12-week workplace exercise program on the quality of life of employees whose primary occupational duties involve prolonged sitting. The final sample comprised 19 participants (6 females and 13 males), aged between 21 and 48 years (M = 32.26; SD = 9.03). Among these participants, 78.9% reported engaging in a hybrid work arrangement, 15.8% followed an on-site work regimen, and 5.3% worked remotely. Furthermore, 84.2% of participants reported sitting for 6 to 8 h per day, while 15.8% reported sitting for between 9 and 12 h daily. The quality of life of participants was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey. A paired samples t-test was employed to examine differences between dependent variables. The results revealed a statistically significant improvement in general health (p < 0.01), vitality (p < 0.01), social functioning (p < 0.05), and the mental health summary measure (p < 0.04). Promoting physical activity through workplace exercise programs offers substantial benefits for workers’ health and quality of life, contributing to the prevention of occupational diseases.
