Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.

Abstract: Introduction. In the context of the COVID-19 pandemic, it is necessary to look for new approaches to the prevention, diagnosis and treatment of skin diseases in the working population. Study objective. To study the hygienic influence of harmful and dangerous factors of the working environment and the severity of the labor process on the structure of the general dermatological morbidity in railway transport workers who ensure the safety of train traffic in the conditions of the COVID-19 pandemic. Materials and methods. The complex of harmful production factors affecting railway transport workers was studied according to the sanitary and hygienic characteristics of the working conditions of employees of the Altai region of the West Siberian Railway of JSC "Russian Railways". The structure of the general dermatological morbidity was studied according to the statistical coupons of outpatient patients who applied to a dermatovenerologist in the CHUZ " CB "Russian Railways-Medicine" Barnaul for the period 2019-2020. Results. The conducted complex of hygienic, epidemiological and statistical studies showed that the combined impact of chemical, meteorological, physical, biological harmful production factors and the severity of the labor process (class 3.1-3.5) in railway transport workers who ensure the safety of train traffic leads to the development of such production-related skin diseases as contact dermatitis and psoriasis. In the context of the COVID-19 pandemic, skin infections (62.8%) predominate over non-infectious dermatoses in the structure of the total dermatological morbidity. The share of primary morbidity increased to 90.8%. The first rank is occupied by pyoderma (47.5%), the second – allergodermatoses (20.0%), the third – mycoses (11.6%). Conclusion. The COVID-19 pandemic leads to changes in the epidemiological and clinical features of dermatoses in the working population, which must be taken into account in their prevention, diagnosis and treatment.

The paper presents the results of hygienic assessment of the working environment and work process factors at surface and underground ore mining operations, ferrous metallurgy plants and aluminum production facilities. It has been established that workers are affected by a complex of production factors (dust, toxic substances, noise, vibration, unfavorable micro climate, etc.), the level of which often exceeds the hygienic standards. The workplace conditions of the primary jobs at these enterprises in 60-80% of cases are classified as hazardous, i.e. Class 3 of various hazard degrees. The incidence of occupational diseases remains high, especially in underground mining and at aluminum production plants. The specific features of mining and metallurgical operations and the severity of unfavorable production factors determine the structure of occupational morbidity. Occupational respiratory diseases are most common among workers in the ferrous metallurgy industry and account for 70.3% in total. Vibration-induced pathologies are most frequently diagnosed among excavator, bulldozer and dump truck operators, and account for 52.9% of all the diagnosed occupational diseases. Hearing organ pathology in the form of neurosensory loss of hearing among workers of mining and metallurgical enterprises ranges from 10.2% (aluminum smelters) to 22.7% (ferrous metallurgy plants) in the occupational morbidity structure. Chronic intoxication with fluorine compounds at aluminum smelters was diagnosed in 68.1% of cases. The results obtained confirm the pressing need to improve the working conditions, introduce preventive measures based on the primary prevention principles, and reduce the risk factors of health problems among the workers.

Introduction. The high prevalence of diseases of the circulatory system of workers in various sectors of the economy, the lack of data on the effects of harmful production factors on the formation of cardiovascular diseases in petrochemical industry workers justify the importance of conducting special studies on these petrochemical complex plants with the aim of assessing cardiovascular risk with the subsequent development of preventive measures. Material and methods. The objects of the study were workers in the production of monomers (ethylene, propylene, ethylbenzene, isoprene, divinyl) of petrochemical enterprises. Hygienic studies of the working conditions of workers included an assessment of the factors of the working environment and the labor process using generally accepted methods. Comprehensive clinical examination of workers included periodic examinations (n = 2634) with calculation of total and relative cardiovascular risk using the SCORE system, using questionnaire data, a Reeder L questionnaire and an in-depth clinical diagnostic medical examination (n = 101) with the definition total cardiovascular risk. Results. The most significant occupational factors of the labor process for workers in the main profession - panmen were established to include the combination of a chemical factor with the occupational noise and labor intensity, with an overall assessment of working conditions 3.2. The class of working conditions of workers of the comparison group (locksmith in instrumentation and automation corresponds to the permissible). There were revealed a high prevalence of arterial hypertension and other factors of cardiovascular risk. A higher dependence of the arterial hypertension level on age and length of service in the group of panmen was established when compared to the mechanicians of instrumentation and automation. Using mathematical models of multiple regression, the likely dynamics of the level of arterial hypertension and the left ventricular myocardial mass index were calculated under the influence of increasing age and other risk predictors. Conclusion. The results of a clinical study showed workers with severe arterial hypertension, a high and very high risk of death from cardiovascular disease on the SCORE scale, a high and very high overall cardiovascular risk, signs of dyslipidemia, obesity, high stress levels to require close attention. It is important to timely diagnose lesions of target organs, to conduct rational prevention aimed at reducing risk factors. According to the results of the study, there were developed preventive measures aimed at reducing cardiovascular morbidity and cardiovascular risk, prolonging the longevity of workers in petrochemical industries.

Emotional Burnout Syndrome

The article presents the results of the risk of developing the burnout syndrome in medical workers, taking into account the influence of hygienic working conditions and the psychological situation in the team. 134 medical workers with working conditions class 2.0, 3.1, and 3.2 were under observation. The ratio of the working conditions of medical workers to the corresponding class was established according to the Manual 2.2006–05 «Hygienic assessment of factors of the working environment and the labor process. Criteria and classification of working conditions». The methodological basis for assessing the level of emotional burnout of a medical worker in a team was a questionnaire developed by V. V. Boyko; the psychological situation in the team was assessed using a questionnaire by A. F. Fiedler. The conducted studies found that with the class of working conditions of doctors at the level of 2.0, the risk of developing emotional burnout after five years of work is 30.7 %. At the level of the class of working conditions 3.2, after five years of work, the burnout among doctors will reach 46.7 %. Against the background of a favorable psychological situation in the team, the probability of developing an emotional burnout syndrome was 20.0 %, with an unfavorable one, it increased to 46.6 %. The results obtained in the course of this study were used as the basis for the development of a method for predicting the risk of developing burnout syndrome in medical professionals in the first five years of work with a sensitivity of 78 % and a specificity of 68 %.
