“…Throughout life, the human body is exposed to various external and internal factors with the development of short-term and long-term processes of corresponding adaptation. This is especially true for individual professional groups associated with the impact of stress factors, in specifically within the employees of mining enterprises [73][74][75]. Heart rate variability analysis of HRV is an adequate method to assess the level of stress in their daily activities.…”

The aim of this study was to assess the genotoxic and cytotoxic effects that occur in miners working underground in rare metal ore mines at ionizing radiation levels within the maximum permissible concentration (MPC) standards using the buccal micronucleus cytome (BMCyt) assay. At the same time, we attempted to identify possible relationships between cytogenetic abnormalities in the buccal epithelium and such physiological indicators as cardiodynamics and the body mass index. The study involved a total of 269 individuals, 236 miners working underground in production related to the mining and enrichment of loparite ores and 33 non-exposed individuals (Russia, Murmansk region). Buccal micronucleus cytome assay and heart rate variability parameters were used. Micronucleus frequency was revealed to be a higher in the exposed group (8.3 ± 1.08‰) than in the non-exposed group (3.3 ± 0.49‰). The repair index showed a statistically significant increase in the non-exposed group (14.9 ± 2.90) compared with the exposed group (6.1 ± 0.74). The frequency of nuclear protrusions correlates significantly with the body mass index in the young miners (≤30 years (r = 0.45)). There is a negative relationship between the micronucleus frequency and the level of organism adaptation (r = −0.24), the vegetative regulation rate (r = −0.20) and the psycho-emotional state (r = −0.30) for miners older than 30 years. The results testify to the possible induction of clastogenic effects and a decrease in the level of reparation in the buccal epithelium cells due to the exposure of a various of production factors in the extraction of loparite ore.

The problem of incidence rate among workers of the main professions of the coal mining industry is traditionally considered from the perspective of occupational pathologies. At the same time, the issues of the spread of production-related somatic diseases among this category of the employable population are undeservedly left without due attention. The objective of the study was assessing the frequency of somatic pathology occurrence in workers of coal pits in the South of Kuzbass. 489 workers of the main professions of coal pits in the South of the Kemerovo region were examined (men aged 22 to 55 years, who were randomized into 2 groups according to the level of exposure to a complex of unfavorable factors of the production environment). The first group with a higher level of exposure to harmful and hazardous production factors of class 3.3 and 3.4 included 196 people: machinists of mining and technological equipment, machinists of drilling rigs, explosives; the second group with the level of danger and harmfulness of class 3.1 and 3.2 consisted of 293 workers, namely, drivers of technological motor vehicles. The study of the frequency of somatic pathology was carried out depending on the length of work experience and the age of the subjects. Each group was divided into subgroups: by the age and work experience. In group 1, somatic pathologies were detected in 52.0% of the cases, in group 2 - in 44.4% (χ2=2.772, p=0.096). In the structure of somatic diseases in the group with a higher class of danger and harmfulness, diseases of the circulatory system (38.24%), diseases of the musculoskeletal system and connective tissue (12.75%) and diseases of the nervous system (8.82%) prevailed; in the group with a lower hazard class there were also diseases of the circulatory system (33.85%), diseases of the musculoskeletal system and connective tissue (14.62%), diseases of the nervous system (12.31%). The frequency of somatic diseases is recorded in a direct linear relationship with the work experience and age of coal pit workers. Limitations. This study is limited to a sample of workers in the main professions of coal pits undergoing periodic medical examinations at the Research Institute for Complex Problems of Hygiene and Occupational Diseases. Conclusion. In the structure of somatic diseases of workers of the main professions of coal pits in the South of Kuzbass, three nosological forms occupy a leading position: diseases of the circulatory system, diseases of the musculoskeletal system and connective tissue, and the nervous system. Among the surveyed workers employed in coal pits with a higher level of exposure to harmful and hazardous production factors, a 100% incidence of somatic diseases was revealed among the respondents aged more than 41 years and with work experience over 21 years. These data should be taken into account when carrying out periodic medical examinations, preventive medical examinations, for the development and implementation of therapeutic and prophylactic measures and post-shift rehabilitation programs. Ethics. The study was conducted in compliance with the standards of the Bioethical Committee of the Research Institute for Complex Problems of Hygiene and Occupational Diseases, established in accordance with the Helsinki Declaration of the World Association "Ethical Principles for Conducting Human Scientific Medical Research" as amended in 2013 and the "Rules of Clinical Practice in the Russian Federation", approved by the Order of the Ministry of Health of the Russian Federation No. 266 of 19.06.2003. All subjects signed an informed consent to participate in the study.
