Objectives: In recent years numerous initiatives aimed at reducing air pollution have been undertaken in Poland. The general objective was to examine the correlation between air pollution measured by the level of particulate matter ≤10 μm in diameter (PM₁₀) and emergency hospitalizations due to chronic obstructive pulmonary disease (COPD) and asthma in 16 Polish cities (capitals of the regions).

Material and methods: The authors aimed to diagnose the situation across 16 cities over a 5‑year period (2014-2019). Data on the number of hospitalizations was retrieved from the national public insurance system, the National Health Fund. A total number of 22 600 emergency hospitalizations was analyzed (12 000 and 10 600 in 2014 and 2019, respectively). The data on air pollution was accessed via the public register of the Chief Inspectorate for Environmental Protection air quality database. The authors of this article have used the data on PM₁₀ daily exposure in each of the 16 cities in 2014 and 2019. Statistical methods included: non-parametric tests, a 2-stage modelling approach for time-series data, and multivariate meta-analysis of the results.

Results: The results indicated that there was a statistically significant decrease in PM₁₀ concentration in 2019 in comparison to 2014 in all cities, mainly in the autumn and winter season. However, the correlation between the improvement in the air quality and a decrease in emergency hospitalizations due to asthma and COPD turned out to not be as strong as expected. The authors observed a strong correlation between PM₁₀ concentrations and hospitalizations due to asthma and COPD, but only when air quality norms were significantly above acceptable levels.

Conclusions: Air pollution measured by PM₁₀ concentration might be used as one of the predictors of the asthma and COPD emergency hospitalization risk, yet other factors like respiratory tract infection, health care organizational aspect, patient self-control, compliance and comorbidities should also be taken into consideration.

Objectives: Fatigue can be the result of overexertion and overload. It occurs when the burdened body does not have enough time for regeneration and biological renewal. The aim of this study was analysis of fatigue based on the subjective feeling in physiotherapists, nurses, and paramedics.

Material and methods: The research covered 193 women and 107 men aged 30-60 years, including 100 physiotherapists, 100 nurses and 100 paramedics with higher education, employed in clinics and hospitals in the Podkarpackie Voivodeship, Poland. The research tool of choice was 30-item Research Committee on Industrial Fatigue Fatigue Scale, adapted into the Polish language by Paluch. The data were analyzed based on ANOVA Kruskal-Wallis test, Mann-Whitney U test and Spearman's rank correlation.

Results: Values determining frequency of decrease in activity were higher in nurses than in physiotherapists (p < 0.001) and paramedics (p = 0.005). Physiotherapists and nurses showed statistically significant positive associations of all fatigue indices with age and seniority. Sex-related differences in the frequency of physical fatigue symptoms have been noted (p = 0.044). Among people working in outpatient clinics and hospitals there were statistically significant differences in the frequency of decrease in activity (p = 0.001) and general level of fatigue (p = 0.031).

Conclusions: In nurses and physiotherapists, the frequency of experiencing ailments increases with age and work experience. This suggests that in the case of these professions it is important to quick identification of signs of fatigue and taking actions to prevent its worsening. Women experience fatigue more often, so they especially need to take steps to prevent and, if necessary, treat this condition. Hospitals should be an area of special involvement in the process of implementing programs to counteract fatigue of employees in the medical services sector.

Objectives: Carpal tunnel syndrome (CTS) is common among office workers and limits functional hand ability and the ability to work. Carpal tunnel syndrome prevention programs implementation are still insufficient among office workers. In view of the fact that physical activity is the best method of preventing musculoskeletal complaints the aim of the study was to evaluate the effectiveness of prevention exercises protocol for hand and wrist pain among office workers.

Material and methods: Study group consists form 62 office workers, reporting complaints of hand and wrist pain. Exercise group it was 49 subjects who performed the exercise protocol and the non-exercise group consisted of 13 subjects. An exercises program, consisting of 7 exercises. The program was planned for daily routine during 8 weeks. The effectiveness of the exercise program was assessed by physical parameters (hand grip and pinch grip strength, force of forearm muscles) and questionnaires (Visual Analog Scale pain scale, Carpal Tunnel Syndrome Symptom Severity Scale, and Carpal Tunnel Syndrome Functional Status Scale functional hand assessment questionnaires) were performed. Assessment was performed before and after the intervention.

Results: Statistical analysis of the data showed significant changes in the value of measured hand grip of the right hand (Z = -2.85, p < 0.01). For pinch grip, changes were significant for both the right (Z = -2.12, p < 0.05) and the left hands (Z = -2.35, p < 0.05). Functional performance improved significantly in bought groups. There was no statistically significant change in the intensity of experienced pain.

Conclusions: The results of the study indicate that performing a preventive exercise program regularly has an effect on increasing forearm muscle strength in a group of office workers. Office workers with symptoms of CTS who exercised regularly had higher results in hand grip and pincer grip strength. Exercises do not affect the level of pain complaints, which may indicate a more complex etiology of pain perception in this study group. Int J Occup Med Environ Health. 2024;37(1):45-57.

Objectives: The specific job demands of the Prison Service (PS) may affect the health of officers. The job demands-resources model (JD-R) model was used to design a survey of the consequences of working subject to particular job demands. The aim was to gain an insight into the relationship between job demands, personal resources, occupational stress and burnout and selected health consequence indicators (such as behaviors associated with the consumption of alcohol, stress symptoms).

Material and methods: A total of 1732 PS officers in Poland were surveyed. The following tools were used as part of the survey: the Copenhagen Psychosocial Questionnaire (COPSOQ II), the Multidimensional Inventory for Assessing Coping Responses (COPE), the Alcohol Use Disorders Identification Test (AUDIT) and a form with a respondent's particulars. Path analysis using partial least squares structural equation modelling (PLS-SEM) was performed.

Results: The assumed hypotheses were partially confirmed by the results. Out of 4 job demands categories only work pace turned out not to be a significant predictor of burnout and stress. For alcohol related behaviors, stress level was the only significant predictor, both as a direct and indirect effect taking into account job demands. It transpired that support from superiors rather than support from colleagues or self-efficacy was a significant moderator in the emotional demands - stress relationship. Limitations of the study and perspectives for its continuation are also presented herein.

Conclusions: Based on the obtained results it may be concluded that job demands and support from superiors do have an impact on stress in the PS group. This is also consistent with available reports in literature. At the same time stress is a significant predictor of alcohol related behaviors. Coping through the use of psychoactive substances was not a significant factor in statistical analyses and it has still not been subject to sufficient scientific analysis.

Objectives: The authors used the National Aeronautics and Space Administration Task Load Index (NASA-TLX) and general health questionnaire to analyze the factors influencing the mental health status and the workload of support nurses during the COVID-19 epidemic.

Material and methods: The authors conducted a cross-sectional survey of 349 support nurses in April-October 2022. Using QuestionStar, a powerful online survey tool, the authors administered surveys to the participants, collected data on the mental health status and workload of support nurses, and analyzed the influencing factors based on the collected data.

Results: A total of 316 questionnaires were successfully collected, with an effective rate of 98.75%. The proportion of support nurses with mental health problems was 25% and the value of the NASA-TLX questionnaire was: M±SD 68.91±7.28 pts. Multi-factor analysis revealed that the number of children, family support, and nursing support location were the influencing factors of mental health status, while the multivariate analysis revealed that the presence of symptoms, nursing support location, support work type, and total 12-item General Health Questionnaire (GHQ-12) score were the influencing factors of the workload of support nurses.

Conclusions: Compared to their counterparts in the plains, nurses working in isolated plateau regions who were caring for children and lacked family support, were more likely to have mental health issues. There was a positive correlation between the changes in GHQ-12 and NASA-TLX scores of the study participants. Compared to their counterparts in the plains and the tropical regions, nurses working in plateau regions had a heavier workload. As part of the follow-up measures to prevent and treat patients impacted by the COVID-19 epidemic, it is important to improve the mental health evaluation, consultation, and treatment of the support nurses to guarantee the high quality of the first-line support work.

Objectives: To assess dietary supplements, functional foods and nutraceuticals use among the patients after myocardial infarction (MI).

Material and methods: The authors prospectively enrolled 100 consecutive patients hospitalized due to MI and remaining under coordinated outpatient care after MI in the authors' cardiology department.

Results: The authors showed that patients within median (interquartile range) 12.30 (10.18-14.57) months after MI use dietary supplements, nutraceuticals and functional foods in their everyday diet. Vitamins (53% patients), especially vitamin D (35%), were the most frequently used dietary supplements. In contrary to common usage of dietary supplements (59%), smaller proportion of patients use functional foods (21%) and nutraceuticals (5%), especially phytosterols. The authors found that the use of over-the-counter (OTC) drugs and dietary supplements is associated with age (participants <60 years old vs. participants ≥60 years old: OTC drugs: N = 8 [20.0%] vs. N = 32 [53.3%], p < 0.001; herbals: N = 3 [7.5%] vs. N = 16 [26.7%], p = 0.019), sex of the patients following MI (females vs. males: vitamins: N = 17 [70.8%] vs. N = 36 [47,4%], p = 0.045; vitamin D: N = 13 [54.2%] vs. N = 22 [28.9%], p = 0.024; omega-3 fatty acids: N = 3 [12.5%] vs. N = 1 [1.3%], p = 0.042; herbals: N = 8 [33.3%] vs. N = 11[14.5%], p = 0.040), as well as the BMI of the participants (BMI < 24.9 vs. BMI ≥ 25.0: multivitamin/ multimineral dietary supplements: N = 3 [15.0%] vs. N = 31 [42.5%], p = 0.035; vitamin B₆: N = 1 [5.0%] vs. N = 21 [28.8%], p = 0.035). In the study group all participants with the age above retirement age have already withdrawn from professional activity and they more often used OTC drugs (N = 14 [25.9%] before retirement age vs. N = 26 [56.5%] above retirement age, p = 0.002).

Conclusions: The patients following MI use supplements, functional foods and nutraceuticals. Their use depends on sex, age, BMI and professional activity. The authors believe that their potential beneficial effects require further evaluation in clinical longitudinal studies. Int J Occup Med Environ Health. 2023;36(6):732-43.

In environmental epidemiology, time series analyses represent a widely used statistical tool. However, though being commonly used, there is soften confusion regarding the specific requirements, such as which link function might be most appropriate, when or how to control for seasonality or how to account for lags. The present overview draws from experiences in other disciplines and discusses the proper execution of time series analyses based on considerations that are relevant in environmental epidemiology. Time series analysis in environmental epidemiology focuses on acute events caused by short-term changes in exposure. These exposures should be fairly wide-spread affecting a large number of persons, usually all inhabitants of a political entity. Pollutants in air or drinking water as well as meteorological factors serve as typical examples. Despite the many time series analyses performed world-wide, some health effects that would lend themselves to that approach are still under-explored. This would include also some neurological and psychiatric endpoints. Int J Occup Med Environ Health. 2023;36(6):704-16.

Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and the military conflicts in Ukraine suggest that workrelated stressors increased during these crises increases work-related stress reactions. Burnout as a long-term consequence of insufficiently compensated for workloads. The regional prevalence of burnout is particularly high among oncologists. The aim of this study was to assess the current risk of burnout within this group of physicians and to examine gender differences through gender-based analysis.

Material and methods: Thirtyseven oncologists (17 men and 20 women aged 46.5±13.6 years [range 26-74 years]) in Kharkiv, Ukraine, participated. The Maslach Burnout Inventory - General Survey (MBI-GS) questionnaire was used to determine the extent of occupational.

Results: Gender, age, and work experience had no effect on the following results. Women demonstrated higher scores in emotional exhaustion and personal accomplishment of the MBI than men. In contrast, men offered higher cynicism scores. The MBI total score was also higher for the male oncologists. Only 1 person of the total sample had risk of burnout.

Conclusions: The results showed a high prevalence of burnout symptoms among Ukrainian oncologists without gender differences. From occupational health perspective behavioral and behavior-preventive measures are needed for clinics and oncologists to counteract the burnout symptoms, e.g. exhaustion or cyniscism. Further studies are needed here to examine the effectiveness of these measures. Int J Occup Med Environ Health. 2023;36(6):717-3.
