On February 1, 2026, Federal Law No. 457-FZ of December 15, 2025, “On the All-Russian Public Organization “Russian Red Cross” came into force, which enshrined the legal status of the organization, its humanitarian mission and principles of operation, as well as its role in the system of providing assistance to the population. At the same time, 2026 marks the 140th anniversary of the Red Cross in the Republic of Tatarstan. The history of the regional humanitarian movement dates back to October 22, 1886, when the Kazan Red Cross Society was founded in Kazan, on the feast day of the Miraculous Kazan Icon of the Mother of God. Taking into account the above, the article is devoted to a comprehensive historical analysis of the evolution of the Red Cross in the Republic of Tatarstan from the late XIX century to the present day. The authors reviewed archival documents, scientific publications, encyclopedic and departmental sources; historical-chronological and historical-comparative methods, as well as elements of institutional analysis and content analysis of regulatory legal acts, were applied. It is shown that the Red Cross has historically developed a sustainable regional model of humanitarian and medical-social assistance in Tatarstan, including training nurses, participating in military conflicts, combating epidemics, developing home care and social assistance, and responding to emergencies. The historical experience of the Red Cross in the Republic of Tatarstan represents a significant resource for the development of modern public health models aimed at reducing social risks, strengthening community resilience, and improving the healthcare system’s preparedness for crises.Contribution of the authors: Anisimov A.A. — research concept and design, writing the text, compilation of the list of literature, statistical data processing; Onishchenko G.G. — research concept and design; Voronin M.V. — collection and processing of material, compilation of the list of literature; Anisimov Yu.A. — collection and processing of material; Safina Z.N. — research concept and design, collection and processing of material.

Introduction. Currently, normative values for the new anthropometric indices (body roundness index (BRI), a body shape index (ABSI), and conicity index (CI)) have not been standardised by age or gender in children.Objective. To determine the normative values of the indices: BRI, ABSI, and CI in healthy Russian children aged 5–12, taking age and gender into account.Materials and methods. This analysis included the anthropometric results of 22,194 healthy children from 46 regions of Russia between 2019 and 2024.Results. Centile data was obtained for each age group (5–12 years) and gender, including the median and percentiles (5, 25, 75 and 95%) of the BRI, ABSI, and CI indices, as well as the waist-to-height ratio (WHtR) and body mass index (BMI). Graphical trends in the studied indices by age showed a decrease with increasing age between 5 and 12 years. The reverse pattern was observed only with the BMI level, which increased with age during this period of child development. Statistically significant gender differences were also found: girls had significantly lower levels of BRI, ABSI, CI, and WHtR than boys, including BMI.Limitations. The narrow age range within which these anthropometric indices were calculated is a limitation of this study. It ranged from 5.5 to 12.5 years.Conclusion. Centile characteristics of the new anthropometric indices as BRI, ABSI, CI and WHtR were obtained. Accumulating data from different age groups will contribute to the systematization of information on these indices, their norms, and their prognostic role in various childhood pathologies.Compliance with ethical standards. The testing of children was carried out as part of a federal project by the Ministry of Sports of the Russian Federation (https://sportchampions.ru/about). The autonomous non-profit physical culture and sports organization "Become a Champion" was a federal experimental (innovative) platform during the project's implementation. The legal representatives of all study participants gave informed voluntary written consent to participate in the testing.Contribution of the authors: Shvartz V.A. — writing the text, statistical data processing; Danilov V.V. — collection and processing of material; Koroleva S.A. — collection and processing of material; Shvartz E.N. — statistical data processing; Permyakov V.E. — collection and processing of material; Donakanyan S.A. — writing the text, compilation of the list of literature; Erastova N.V. — research concept and design.

Introduction. The provision of qualified personnel to medical institutions providing primary health care remains a significant problem in Russian healthcare, which necessitates a comprehensive assessment of personnel provision at the regional healthcare system level for subsequent rational planning of human resources.The purpose of the study is to develop an algorithm for making managerial decisions in the field of healthcare personnel policy at the regional level based on the results of an analysis of the staffing of primary healthcare providers conducted using the index method.Materials and methods. The research materials include the results of an analysis of the staffing of primary health care facilities by doctors over 2018–2022, using the methodology for calculating the human resources well-being index in healthcare developed by the team of authors at the Russian Research Institute of Health, which was modified for the study of human resources providing primary health care. The research base includes all regions of the Russian Federation. The methodological framework is based on organizational modeling and analytical methods.Results. Based on the data on the values of the human resources well-being index in healthcare for 2022 and the trends in its development, there were identified four clusters, included the constituent entities of the Russian Federation that have similar characteristics of the human resources well-being index in healthcare. The grouping of regions into clusters allowed for a differentiated approach to making management decisions in the field of implemented human resources policy in healthcare at the regional level based on a specially developed algorithm.Limitations of the study. The study materials are limited to the results of the analysis of staffing by primary health care physicians using the methodology for calculating the human resources well-being index in healthcare.Conclusions. The use of the management decision-making algorithm provides an opportunity to choose the tactics of further actions by the executive authorities of the constituent entities of the Russian Federation in relation to the implemented personnel policy in healthcare at the regional level to improve the performance of medical institutions providing primary health care.Compliance with ethical standards. This study does not require a conclusion from the Local Ethics Committee.Contribution of the authors: Senotrusova Yu.E. — collection and processing of material, statistical data processing, writing of the text; Khodakova O.V. — editing; Senotrusova Yu.E., Khodakova O.V. — research concept and design, approval of the final version of the article, responsibility for the integrity of all parts of the article.Funding.

Introduction. The most important reasons for the progression of eye diseases in children, in addition to genetic factors, is insufficient artificial lighting in classrooms. Creating a light environment that is safe from a hygienic point of view is an important task of managing the learning process in a preschool institution.The purpose of the study: studying the influence of artificial lighting on the visual analyzer in children and hygienic assessment of the formation of health risks caused by eye diseases during the provision of education and training services in preschool educational institutions.Materials and methods. A retrospective analysis of measurements of artificial lighting in a preschool institution over a long-term period and forms of medical statistical reporting were performed. Measurements of artificial illumination were carried out in group cells of preschool institutions. Observation/control groups were formed and the pathological incidence of eye diseases in children was assessed. Correlation analysis was applied, relative risk (RR) was calculated and health risk was calculated using categorization of risk levels.Results. Exceeding the level of illumination to the hygienic standard (HS) statistically significantly increases the likelihood of developing general pathological diseases of the eye and its adnexal apparatus in children (RR = 3.2; CI = 1.6–6.4); a value below the HS determines a negative trend in the development of these diseases (RR = 1.4; CI = 0.6–3.1). The quantitative value of the health risk corresponds to the alarming level from exposure to LED and fluorescent lighting (7.0 ∙ 10–⁴; 6.0 ∙ 10–⁴, respectively), which is subject to periodic monitoring and requires additional preventive measures.Limitations. The conduction of the study in preschool educational institutions limits the possibility of extrapolating the research results to other types of educational institutions that differ in other conditions for the provision of services for the upbringing and education of children.Conclusion. Artificial illumination, both at the HS level and exceeding it, can cause a risk to the health of the visual analyzer in children. In this regard, it is advisable to establish the HS of artificial illumination in preschool institutions in the form of a range of values.Compliance with ethical standards. An ethical review was not required for this work.Contribution of the authors: Shur P.Z. — concept and design of the study, editing; Redko S.V., Lir D.N., Fokin V.A., Shtina I.E. — collecting and processing material, writing text, compiling a list of references.

Introduction. Spring water is in high demand among consumers for drinking and household purposes. High population density and industrial development cause environmental damage to the natural environment, including the groundwater of the Moscow region. At the same time, the incidence due to the water factor is increasing. The end user does not have reliable information about the quality and safety of water.Purpose. To study the quality and safety of spring water in the Moscow region according to sanitary and hygienic indicators.Materials and methods. The article presents the results of a large-scale two-stage (spring–summer 2024 and summer 2025) study of spring water in 14 districts of the Moscow region on sanitary, chemical, organoleptic, and microbiological indicators.Results. Hygienic characteristics of the condition of the nearby spring areas have been compiled, and potential contaminating objects have been identified. The percentage of springs in the Moscow region has been determined, the condition of which allows the end consumer using water without pretreatment. The main deviations in sanitary and hygienic indicators and the probable causes of their occurrence have been established. A list of priority indicators and standards recommended for monitoring and sanitary-epidemiological supervision of the quality and safety of spring water is proposed.Research limitations. The study has regional limitations (Moscow region).Conclusion. The trend in deterioration in the quality and safety of spring water during the spring and summer periods determines the need for measures for water protection and informing the public about the ways of using water for domestic and drinking use to minimize the risks of the spread of acute intestinal infections among the population.Compliance with ethical standards. Research does not require approval by an ethics committee.Contribution of the authors: Trukhina G.M. — research concept and design, analysis and statistical data processing, writing the text, compilation of the list of literature; Mikailova O.M., Drozd N.A. — editing, statistical data processing; Borisova N.A., Samotoina A.A. — collection and processing of material, writing the text, statistical data processing.
