Medical personnel in rural areas: trends in key indicators
Abstract
Introduction. Provision of rural health care with medical personnel is one of the main problems and a priority area for the development of the health care system. In this regard, it is necessary to monitor key indicators to address the issues of planning and forecasting the availability of medical care.
The purpose of the study. To analyze the trend in key indicators of provision with doctors and specialists with secondary medical education in medical institutions located in rural areas of the Russian Federation.
Materials and methods. The statistical materials “Resources and activities of medical health care institutions. Medical personnel: statistical materials” on the provision of medical institutions with medical personnel in the country as a whole, federal districts and subjects of the Russian Federation for the period from 2018 to 2022. When calculating the indicators, we were guided by the methodological recommendations of the Ministry of Health of Russia. Analytical and statistical methods were used in the research process. Calculations were performed using Excel 2019 spreadsheets.
Results. In the Russian Federation as a whole during the period under study, the number of physicians in rural health care decreased by 9% and the number of middle medical personnel (MMP) by 10.1%. The analysis of the age structure in medical workers working in rural areas revealed an increase in the average age of both doctors and MMP.
Research limitations. The research materials are limited to the results of the analysis of quantitative data obtained from the forms of federal statistical observation.
Conclusion. Rural health care employs up to 9% of physicians out of the total number of physician personnel, and the average medical personnel accounts for 34% of the total number of employees of health care organizations in the country. However, the provision of the population with medical and paramedical personnel remains low, staffing of regular positions is decreasing. The subjects with the most pronounced “ageing” and “rejuvenation” of both medical and paramedical personnel have been identified.
Compliance with ethical standards. This study does not require a conclusion from the Local Ethics Committee.

Assessment of the economic efficiency of preventive measures targeted at reducing the incidence of cardiovascular diseases in the workforce
Abstract
Introduction. This article presents a model for assessing the economic effectiveness of preventive programs implemented in the workplace and reducing the risk of illness among employees; we chose cardiovascular diseases (CVDs) for the purposes of exemplifying our model.
The purpose of the study is to develop a financial model (calculator) for assessing the cost-effectiveness of expenditures on preventive programs and on ergonomic interventions aimed at reducing the risk of CVDs among employees.
Materials and methods. The model is based on the methodology of cost-benefit analysis, which allows comparing the costs of a preventive measure with the benefits of its implementation. The costs include expenses on equipment and labour involved in installing and deploying this equipment, while the benefits refer to savings on costs that the employer would otherwise have to bear as a consequence of having his employees fall ill.
Results. The model obtained allows users comparing different ways in which these preventive programs may be implemented, as well as individual measures aimed at modifying different risk factors for the same disease. Although this study is limited to CVDs, the proposed model can be used to evaluate the economic effectiveness of preventive programs aimed at reducing the risk of disability caused by other diseases.
Research limitations. The assumptions of the model impose several limitations on the obtained estimates: cases in which employees continue to work while sick are not considered, and it is assumed that the decrease in the incidence of illnesses as a result of intervention remains constant during the programs implementation period.
Conclusion. The model can be used as a tool to substantiate any decisions made in the matters of choosing whether to implement a preventive program aimed at reducing the risk of morbidity of enterprise employees; the model can also serve as a tool that can be used to calculate which of the preventive options available is likely to lead to the most desirable outcome.
Compliance with ethical standards: the study does not require the submission of a conclusion from the biomedical ethics committee or any other documents.

Economic and industrial characteristics of Russian regions influencing individual risk of death: results of a prospective ESSE-RF study
Abstract
Introduction. The territorial characteristics of the population’s residence can influence individual health risks. For the Russian population, the influence of regional living conditions on the individual probability of behavioural risk factors and the development of a number of diseases is shown.
The purpose of the study is on the base on prospective observation data to assess the individual risks of death from the regional living conditions of the Russian population.
Materials and methods. Individual indicators were taken from the Russian study ESSE-RF 2013–2014, with subsequent prospective observation during 2015–2021. (sixteen thousand three hundred twenty nine people of 25–64 years from 10 regions of Russia). To assess regional living conditions, 4 regional indices were used: Socio-geographical, Demographic, Industrial, Economic. A proportional hazards model (Cox regression) was used to estimate associations, calculating odds ratios and 95% confidence intervals, adjusting for a wide range of individual sociodemographic, behavioural and clinical characteristics.
Results. In the full model, living in an economically developed region reduces the individual probability of death (0.55; 0.43–0.71). The contribution of the Economic Index, compared to individual traditional health risk factors, is quite high. The influence of the Economic Index is most pronounced in men and people aged of 55–64 years. In the group of people without higher education, living in an industrialized region increases the individual probability of death (1.36; 1.05–1.76).
Research limitations. To represent a Russian representative sample, 10 regions is sufficient, however, when considering regional characteristics, of course, more stable patterns of influence would be obtained if a larger number of regions were involved, with all the diversity of regional living conditions of the population.
Conclusion. The study made it possible to identify the dependence of the individual probability of death on the regional characteristics of the Russian population, which expands the fundamental understanding of the cause-and-effect dependencies of human health on environmental factors and makes it possible to take into account environmental factors in predicting the health of the population.
Compliance with ethical standards. The study was approved by local ethical committees: National Medical Research Center for Therapy and Preventive Medicine (Moscow), protocol No. 07-03/12 dated 07.03.2012. All patients signed an informed consent to participate in the study.

State policy considering socio-economic well-being in the elder people in the Irkutsk region
Abstract
Introduction. Population aging creates new qualitatively different demand for socio-economic care. Since this phenomenon is dynamic and represents a rapidly emerging task, the state population policy needs to respond accordingly.
The purpose of the study. To assess the productiveness of the practice of applying regional legislation to ensure the socio-economic well-being in the elder people of the population of the Irkutsk region.
Materials and methods. The Irkstat provided materials compiling the database. We used accounting tables: 25_2PH — Population by sex and age. We chose 2014–2021 as the period of the study. As part of the study, we carried out the calculation of the indices of provision of social services in various forms, calculated per 1000 population. The integral indicator of efficiency was calculated.
Results. The volumes of social services rendered, implemented in various forms, change dynamically. This process is evidenced by the change in the indices showing the amount of the provided social services for the study period of 2014–2021. The index of providing social services at home increased from 23.6 per 1.000 people to 27.9, while the volume of services provided in a stationary form decreased from 8.5 to 7.8 per 1000 people. After analyzing the approaches of the authorities to the implementation of the requirements established by the current legislation, we concluded that the observed fluctuations in the volume of assistance are primarily related to the implementation of the principles of performance-based budgeting.
Research limitations. The research materials are limited to the results of the analysis of data from regional projects for 2019–2024: “Social support for the population”, “Social services for the population”, “Development and implementation of a program of systemic support and improvement of the quality of life of senior citizens (Irkutsk region)”, passports and plans of the departmental target program for 2019–2024 “Social services for the population of the Irkutsk region”.
Conclusion. In connection with the process of population aging, the state demographic policy to ensure socio-economic well-being is currently aimed at optimizing the spending of budgetary funds by redistributing the amount of assistance according to its forms by expanding hospital replacement technologies.
Compliance with ethical standards. The study does not require the submission of the opinion of the biomedical ethics committee or other documents.

Providing medical and social care to patients with orphan diseases (literature review)
Abstract
Rare (orphan) diseases (RD) are diseases that affect a small part of the population. However, although each disease affects a small number of people, they collectively form a large subpopulation. Currently, there are up to 8,000 rare diseases known in the world, affecting approximately 6–8% of the planet’s population. Rare diseases require a special approach from healthcare. Although many countries around the world are already implementing significant opportunities to support patients and their families, challenges and unmet needs remain. To further improve the health-related quality of life of RD patients, it is important to identify common patterns in the existing problems and needs of this category of citizens.
The purpose of this work was to analyze modern studies conducted in developed countries of the world, based on surveys of patients with various RD and their families about existing problems and needs.
We searched PubMed and Google Scholar for literature on psychosocial issues in RD patients. The results showed the main problems and needs to be diagnostic issues (long period of time before diagnosis, presence of errors, need to visit a large number of doctors to make a final diagnosis, the process of announcing the results), lack or inadequacy of psychological support, unsatisfactory material support, poor awareness of the disease and existing health care support. The work also makes proposals for the further development of health care services that provide assistance and support to RD patients and their families, to solve these problems and meet the corresponding needs.

SOCIOLOGY OF MEDICINE
Perception of medical care conditions in an infectious diseases hospital by patients with COVID-19 (using the example of Nizhny Novgorod)
Abstract
Introduction. The pandemic of a new type of coronavirus infection has negatively affected on the lives of Russians, causing them to feel fear for their lives. In this connection, there was a transformation of the social roles of the patient and the doctor, as well as a change in the conditions and boundaries of their interaction.
The purpose of this study was to evaluate the perception of COVID-19 patients of the conditions of medical care in an infectious diseases hospital.
Materials and methods. The study was conducted by questionnaire in two stages: in the summer of 2020 and in the summer of 2021, two hundred eighteen respondents participated.
Results. The pandemic significantly changed the lifestyle of the respondents: only 9.5 ± 3.2% of the respondents at the first stage of the survey led their usual lifestyle before the disease, a year later the proportion of such study participants had no statistical significance. Assessing the working conditions in doctors, 94.1 ± 3.1% of respondents at the first stage of the survey and 85.6 ± 2.9% at the second stage reported that they consider them difficult. 85.7 ± 3.8% of the participants at the first stage of the survey and 70.1 ± 3.9% of the second estimated the amount of payments to hospital medical workers as insufficient, taking into account working conditions and the level of workload of medical personnel (pvalue < 0.005). All patients, without exception, were satisfied with the quality of provided medical care, despite the existing dissatisfaction with medical nutrition and living conditions.
Research limitations. The study materials are limited to the results of questionnaire survey of patients at two infectious diseases hospitals of N. Novgorod, conducted from June to August 2020 and 2021.
Conclusion. Patients with new-onset coronavirus complications at discharge were satisfied with their conditions of care at an infectious disease hospital. The facts of dissatisfaction with the therapeutic nutrition or living conditions noted by the patients did not influence their satisfaction.
Compliance with ethical standards. Conclusion of the local Ethics Committee N 7 dated 05/31/2022.

TOPICAL ISSUES OF HYGIENE
Hygienic aspects of accumulation of arsenic in fish grown in natural and artificial conditions
Abstract
Introduction. World consumption of fish per capita will reach 21.2 kg in 2030, compared to an average of 20.5 kg in 2018–2020. Fish accumulate arsenic, which then enters the human body with food. An acute problem is the hygienic aspects of accumulation of arsenic in fish grown in natural and artificial (aquaculture) conditions.
Purpose of the study. Assessment of hygienic safety for consumers when eating fish grown under natural conditions versus those raised on fish farms.
Materials and methods. The objects of the study are Siberian sturgeon (Acipenser baerii). The methods of isolating total arsenic and inorganic arsenic by microwave decomposition, as well as the method of sequential fractionation for isolating arsenic in the form of complex organic compounds were used. Arsenic in all fractions and forms of existence of the element was determined by ICP-MC. Carcinogenic and non-carcinogenic risks were calculated.
Results. Data on arsenic distribution in sturgeon parts and organs were obtained. Based on this, the following sequence of total arsenic decrease was compiled: liver > (intestine + stomach) with contents > caviar ≈ fillet > head (without gills) > skeleton with visiga > gills > skin without scales. Up to 27% of all accumulated arsenic is associated with adipose tissue with the formation of complex compounds with lipids. The levels of carcinogenic risk for inorganic forms of arsenic according to the acceptance criteria are below the target risk value. None of the sturgeon samples had non-carcinogenic risk values > 1.
Research limitations. Only one species of fish (sturgeon) was used in the studies.
Conclusion. The conducted sequential fractionation of arsenic forms allowed detecting the proportion of fat-soluble, water-soluble arsenic compounds in sturgeon fillets and caviar in relation to the total content. Comparative analysis of arsenic compounds in fish grown in natural and artificial conditions did not reveal significant differences in its distribution between the two methods of cultivation. As a result of the conducted studies, the use of Siberian sturgeon was established to do not pose a danger to human health.
Compliance with ethical standards. The study does not require a biomedical ethics committee opinion.

Safety of food products treated with ionizing radiation (literature review)
Abstract
Irradiation of food products with ionizing radiation (OII) is a promising area in the food industry, which is actively developing and using in various countries of the world. This method allows effectively combating dangerous pathogens, prevent food spoilage and extend their shelf life. Food irradiation is approved by the Food and Agriculture Organization of the United Nations (FAO), WHO, and Codex Alimentarius as a safe method of food preservation. Currently, irradiation of several categories of food is allowed in Russia. In this regard, safety issues for consumers of such products are acute. Food exposure leads to radiation, microbiological, and chemical changes in food, but their safety is comparable to that of products treated with other traditional processing methods such as heating, pasteurization and canning. Irradiation of food products does not lead to their radioactivity. According to the Codex Alimentarius, the maximum absorbed dose during irradiation should not exceed 10 kGy. Irradiation of fatty foods leads to the formation of 2-alkylcyclobutanones (2-ACB). Cytotoxic and genotoxic effects of 2-ACB have been confirmed in studies, but only in the case of high concentrations of these compounds. In products irradiated with doses up to 59 kGy, 2-batteries are formed in low concentrations, therefore, irradiation of food products also does not lead to mutagenic or genotoxic effects. The research data confirm the absence of radiation, microbiological, and toxicological risks if the recommended doses and regimens are observed.

Sports nutrition as an example of effective implementation of innovative trends in nutrition: personalization and digitalization (literature review)
Abstract
The nutritional status in an athlete depends on the individual genetic characteristics of the body, the level of physical and psycho-emotional stress, and a balanced diet with the inclusion of specialized food products and dietary supplements. The development of big data analytics and artificial intelligence can contribute to the development of nutritional recommendations at the individual or stratified level.
The purpose of the review is to analyze and summarize research papers devoted to the possibilities of using digital technologies, deep machine learning techniques, and artificial intelligence in the field of sports nutrition to ensure a personalized approach to improving professional success. There were studied papers published in 2004–2024 in domestic and foreign electronic databases: Web of Science, Scopus, eLIBRARY.RU, Russian State Library, library collection of the Federal State Budgetary Scientific Institution “Federal Research Center of Nutrition and Biotechnology”.
The potential for AI-based technologies in sports nutrition is extremely diverse: dietary assessment, recognition and tracking of food diversity, predictive modelling of athletic performance and non-communicable diseases, and selection of personalized diets. To ensure sustainable growth in the coverage of digital products and technologies, further directions for their application in sports medicine should be aimed at improving the quality and standardization of data and reducing algorithmic bias.

Assessment of the influence of meteorological and environmental factors on diseases of the circulatory system in the population of the industrial region
Abstract
Introduction. In the context of global climate changes occurring on the planet, an important task is to develop modern methods for modelling and forecasting the complex influence of meteorological and environmental components of the environment on physical health, for the rapid development of measures to prevent diseases of the cardiovascular system in human.
The purpose. Development of an effective method for hygienic assessment of the risk of cardiovascular pathology, which is formed under the influence of the complex effects of meteorological and chemical environmental factors.
Materials and methods. The average annual and seasonal fluctuations of meteorological factors were studied. Bioclimatic indices, the index of pathogenicity of the meteorological situation, and severity of the weather were calculated. Concentrations of chemicals in atmospheric air were assessed, and the influence of meteorological environmental factors on the incidence of cardiovascular pathology in the population living in an industrial region was analyzed.
Results. Based on the conducted studies, an unfavourable combined effect of meteorological components of the environment on thermoregulation processes in residents of an industrial region has been established. The relationship between the average daily wind speed and the seasonal excess of the maximum permissible concentrations of certain substances in the atmospheric air over a number of years has been revealed. The combination of seasonal fluctuations in meteorological factors with increased levels of pollution of the city’s atmospheric air with heavy metals are factors that increase the incidence of cardiovascular pathology in the population.
Research limitations. The studies had no methodological or administrative restrictions.
Conclusions: There has been developed the method for calculating and assessing the risk of cardiovascular pathology, formed under the influence of the complex effects of meteorological and chemical environmental factors.
Compliance with ethical standards. The study does not require the submission of a conclusion from the biomedical ethics committee or other documents.

Features of the immune and genetic profile in children suffering from diseases of the cardiovascular system associated with contamination of biological media with nickel and copper
Abstract
Introduction. A pressing issue is the possible impact of exposure to heavy metals on the occurrence and progression of cardiovascular diseases (CVD) among the pediatric population.
Purpose. To evaluate the immune and genetic profile in CVD children under environment contamination with nickel and copper.
Materials and methods. Ninety seven children living in the industrial center of the Perm region were examined. Observation group (45 CVD patients), comparison group (52 cases) without CVD. Annexin V and CD16+CD56+ receptors were determined by cytofluorometry. Content of specific IgE to nickel and IgG to copper was detected by the allergosorbent method. SNP genotyping was performed using real-time PCR.
Results. In the observation group, there was noted an increase in the concentration of nickel and copper; hyperproduction of IgG to copper, IgE to nickel by 1.8 and 1.5 times; activation of CD16+CD56+ receptors by 1.2–1.6 times and annexin V by 1.5–4.5 times. Prevalence in the observation group of the C allele of the IL-6 G174C gene (RR = 1.62; 95% CI = 1.01–2.59) and the C allele of the MTHFR C677T gene (RR = 1.39; 95% CI = 1.07–1.79) increase the relative risk of CVD by 1.6 and 1.4 times.
Research limitations. 3–6 years children, in the observation group the presence of CVD.
Conclusion. Allele C of the MTHFR C677T rs1801133 gene forms a relative risk (RR = 1.39; 95% CI = 1.07–1.79) of imbalance in the expression of sulfur-containing amino acids, impaired expression of allele C of the IL-6 G174C rs1800795 gene (RR = 1.62; 95% CI = 1.01–2.59), results in overexpression of CD16+CD56+, Annexin V underlying the etiopathogenesis of CVD diseases.

Prevention of alimentary-dependent diseases using physiotherapy technologies in aviation engineering workers
Abstract
Introduction. Unfavourable working conditions combined with an unbalanced diet are risk factors for the formation of metabolic disorders and nutritional-dependent diseases. The nutrition factor is of great importance in maintaining the health of industrial workers. A promising direction in the prevention of diseases caused by malnutrition is the use of modern physiotherapy techniques that simultaneously affect homeostasis systems at various levels.
The purpose of the study is to evaluate the effectiveness of a multimodal physiotherapy unit in the prevention of alimentary-dependent diseases in aviation engineering workers.
Materials and methods. A study of working conditions, the nature of nutrition, and the health status of aviation engineering workers has been conducted. The effectiveness of wellness measures using multimodal physiotherapy equipment, the Alpha Oxy SPASystem capsule, which includes combined effects of heat, general vibration, aromatherapy, and oxygen therapy, was evaluated. The duration of the procedure is 30 minutes, 10 procedures per course. The trend in anthropometric and laboratory parameters were evaluated before and after the end of treatment.
Results. A violation of the structure and composition of average daily diets, consumption of micro- and macro nutrients among workers in aviation engineering has been revealed. An increased risk of developing alimentary-dependent diseases and related disorders of anthropometric and biochemical parameters in the group of workers with an unbalanced diet has been identified. A positive effect of the multimodal physiotherapy system on the anthropometric, biochemical parameters of lipid and carbohydrate metabolism, and the antioxidant system has been obtained.
Research limitations. The limitation of this work is the small group of aviation engineering workers.
Conclusions. The results of the study make it possible to recommend a multimodal physiotherapy system in comprehensive treatment and wellness programs for the prevention of alimentary-dependent diseases in workers of harmful industries.

CHILDREN AND ADOLESCENTS’ HEALTH
The role of nutrition in the prevention and treatment of atopic dermatitis (literature review)
Abstract
Atopic dermatitis (AD) is a multifactorial chronic inflammatory skin disease with a high prevalence in children and adults. The disease characterized by pruritus, recurrent course is associated with other allergic conditions such as food allergies and asthma, forming the concept of “atopic march”. Genetic mutations affect the barrier function of the skin, creating conditions for allergens to penetrate and inflammation to develop. Environmental factors, including air pollution, nutrition, and microbiota, also play a significant role in the etiology and pathogenesis of AD.
Nutrition during infancy and childhood is a key factor influencing growth and development in childhood, contributing to health and disease prevention throughout life. Breastfeeding and the diversity of the mother’s diet may influence the risk of AD in children. The consumption of certain foods during pregnancy and the specifics of complementary feeding may contribute to the development or decrease the risk of allergy in the child. The gut microbiota plays an important role in modulating immune responses and tolerance to food allergens.
Scopus, Web of Science, Medline, The Cochrane Library, EMBASE, Global Health and RISC databases were used to create this review article. The article analyzes the literature on the peculiarities of the preventive diet in pregnant women, nursing mothers, and children in families with an aggravated hereditary history of atopic dermatitis. The review emphasizes the need for further research to identify the influence of early life nutrition on the risk of allergic diseases. The article discusses current approaches to the prevention and treatment of AD, including the use of probiotics, dietary diversity, and breastfeeding support as meaningful strategies to reduce the risk of AD and allergic diseases in children.

Clinical and epidemiological aspects of giardiasis in children
Abstract
The purpose of the study. To study the seroprevalence of Giardia lamblia among the pediatric population in the Astrakhan region in 2019–2022, associated with certain determinants such as age, regional prevalence, the presence or absence of clinical manifestations and risk factors, and analyze the effectiveness and adequacy of diagnostic and therapeutic procedures.
Materials and methods. Over 2019–2022, six thousand eight hundred fifty episodes of parasitic infections were registered in the Astrakhan region, of which 95.1%, or 6,523 cases, accounted for children. Giardiasis accounted for 19.6% (1,240 cases) of all parasitic infections, while children accounted for 82.8% (1,109 cases).
The results of the study. In the Astrakhan region, giardiasis is characterized by the same prevalence in urban and rural areas.
In the majority of cases, patients complained of various clinical symptoms and signs characteristic of this disease (87.2 (967 cases)), on the basis of which giardiasis was suspected and further examination of the child was carried out.
When collecting the epidanamnesis, it was found that 90.4% of children (1002 cases) said that they did not follow personal hygiene well. In addition, onychophagia (48.6% (539 cases)), geophagia (37.9% (420 cases)), and close contact with animals (including pets) was detected in more than half of all cases — 76.8% or 852 cases.
Research limitations. The limiting factors in the study are the epidemiological maps of children infected with lamblia.
Conclusions. During the study period, giardiasis was more often found among school-age children in the Astrakhan region. The clinical picture was most often dominated by pain in the epigastric region, complaints of decreased appetite and diarrhea. In all cases, giardiasis was diagnosed based on laboratory confirmation of the presence of cysts.
Compliance with ethical standards. The conducted study does not require the submission of the conclusion of the committee on biomedical ethics or other documents, since during the preparation of the work, epidemiological records of persons with giardia were used, as well as extracts from outpatient admission cards of children’s polyclinics.
