Abstract
Introduction. Obesity is recognized as a chronic disease; however, in clinical practice it is frequently not verified as an independent diagnosis, which limits the timely detection of comorbid conditions and initiation of preventive interventions.
Aim of the study was to assess the prevalence of undiagnosed obesity and characterize its clinical and nutritional profile in a large digital cohort.
Materials and methods. A retrospective case–control study was conducted using data from a digital platform (2022–2025). The cohort included 3,267 adults,dividing in the following groups: hidden obesity (body mass index ≥30 kg/m² without diagnosis, n=636), diagnosed obesity (n=31), control (body mass index 18.5–24.9 kg/m², n=1,629). Statistics: Pearson’s chi-square test, Welch’s t-test, Mann–Whitney U-test.
Results and discussion. Actual obesity prevalence was 20.3%, while the diagnosis was recorded in was only 0.9%. Hidden obesity accounted for 19.5% of the cohort (95% confidence interval: 18.1–20.9%). Hypertension and diabetes rates in the hidden obesity group were 3.6 and 3.9 times lower than in the diagnosed group (significance level <0.001), indicating a diagnostic trigger effect. Patients with hidden obesity consumed significantly less energy and protein per kilogram of body weight (significance level <0.001) but had higher absolute caloric intake and elevated sodium and cholesterol consumption.
Conclusion. Hidden obesity affects every fifth adult and is associated with systematic underdiagnosis of metabolic risks. Implementation of automated body mass index screening and algorithmic diagnosis verification in primary care is essential for early preventive interventions.

Abstract
Introduction. Mechanization of underground mining did not have an expected positive impact on occupational morbidity among miners in the Murmansk region.
Aim of the study was to analyze the occupational health characteristics of various mining underground equipment operators in the Murmansk region.
Materials and Methods. The study examined the working conditions and data on 2,119 non-occupational and 370 occupational diseases in five groups of various mining equipment operators (n=784). The observation period was from 2003 to 2023.
Results. The working conditions of mining equipment operators corresponded to classes 3.2-3.3. An analysis of data from 2003 to 2023 revealed the specific features of the structure of non-professional and professional pathologies among miners. In all five groups, musculoskeletal pathologies accounted for the largest share of non-occupational disease classes, with a higher prevalence among drilling and vibratory transport unit operators than among underground self-propelled machine operators (p=0.002 and p<0.001) and electric locomotive operators (p=0.046 and p=0.019).The most common cause of occupational diseases was increased workload: from 41.2% among underground self-propelled machine operators to 71.4% in drillers. The proportion of workers, who developed occupational diseases over 21 years-period, ranged from 18.9% among electric locomotive drivers to 37.8% in vibratory transport unit operators. In the structure of occupational diseases in drillers, loader-dump machine operators, and vibratory transport unit operators, the largest shares belonged to musculoskeletal diseases (68.2%), effects of vibration (35.3%), and sensorineural hearing loss (39.1%), respectively. The morbidity rate in miners exceeded the national average for underground ore mining by 1.40-2.76 times.
Conclusion. In 2003–2023, operators of modern mining equipment continued to experience hazardous working conditions and there was no reduction in the number of workers with primary occupational pathology or in the number of occupational diseases. In order to improve the effectiveness of preventive measures, it is advisable to implement them taking into account the established health disorders in different groups of operators.

Abstract
Introduction. The analytical review of literature presents information concerning modern views on predisposing, directly causal and provoking factors of development, as well as triggering, supporting pathogenetic mechanisms of chronic allergic inflammation in IgE-mediated atopic dermatitis in adolescence, since one of the actual and unresolved problems of pediatrics remains insufficient effectiveness of existing therapeutic approaches and methods of prevention in atopic dermatitis. For many decades, one of the most pressing and unresolved problems in pediatrics has been the insufficient effectiveness of existing therapeutic approaches and prevention methods for atopic dermatitis. This pathological process occurs in all age groups of childhood, as well as in adolescents. The article also discusses the principles of selecting therapy for adolescents with this pathological process.
Conclusion. In understanding the patterns of development of IgE-mediated atopic dermatitis, it is important to study the role of vitamin D in the pathogenetic mechanisms of skin barrier damage and, separately, the development of itching sensations, which are associated with the failure of structural and antimicrobial proteins in the epidermis and the initiation of the above-described immune reactions directly in the skin, as well as with central and peripheral neurogenic effects on the skin. Conducting studies in adolescents with IgE-mediated atopic dermatitis could potentially establish a link between vitamin D content and central and peripheral neurogenic activity. This information could provide a basis for developing therapeutic approaches in adolescents with this pathological condition that aim to modulate neurogenic effects on the skin through vitamin D.

Abstract
Introduction. Despite the evolution and high efficiency of rotator cuff tendon repair techniques, a high frequency of recurrent ruptures and non-accretions remains. reruptures. There is no consensus regarding the choice of repair technique.
Aim of the study was to analyse the mid-term functional and structural results of arthroscopic transosseous suturing using the free-hand technique in patients with medium sized rotator cuff tears.
Materials and Methods. A prospective observational cohort cross-sectional study of rotator cuff integrity assessed by MRI performed 12 months after arthroscopic transosseous repair in 168 patients with tears ranging from 2 to 4 cm in anterior-to-posterior size, as well as their functional outcomes using the ASES, Constant, and VAS scales, measuring range of motion deficits and assessing the scapulohumeral rhythm after 24 months. The data were analyzed taking into account patient characteristics, bone mineral density of the greater tubercle of the humerus, the severity of fatty infiltration of the supraspinatus muscle, osteoarthritis and tear size.
Results. Complete healing of the supraspinatus tendon occurred in 143 patients (85.1%), absence of gap but tendon thinning occurred in 14 patients (8.3%), and recurrent rupture or non-healing occurred in 11 patients (6.5%). Statistically significant risk factors for non-healing were tear size, fatty infiltration of the supraspinatus muscle and decrease of acromiohumeral interval. No clinical or EMG signs of axillary nerve injury were registered. Excellent and good functional scale scores were obtained in 146 patients (86.9%). Deterioration of functional results in the remaining cases was associated with suture failure, osteoarthritis progression, pain syndrome and limited shoulder motion.
Conclusion. Arthroscopic transosseous repair using the "freehand" technique is an effective treatment for patients with full-thickness rotator cuff tendon tears ranging in size from 2 to 4 cm. Risk factors for non-healing include tear size, fatty infiltration of the muscle tissue and persistent superior migration of the humeral head.

Abstract
Introduction. Multimorbidity and comorbid conditions play a crucial role in the formation of morbidity and mortality in chronic respiratory diseases and are significantly modified by new coronavirus infection.
Aim of the study was to analyze the epidemiological profile of multimorbidity and comorbid conditions in chronic respiratory diseases in hospitalized patients in the context of the spread of COVID-19.
Materials and methods. A retrospective epidemiological analysis of data from the medical information system of a multidisciplinary hospital in Saint Petersburg was performed for the period 2017-2025. The study was conducted in three periods: pre-epidemic (2017-2019), epidemic (2020-2022) and period of declining epidemic intensity (2023-2025). The study evaluated the structure of concomitant diseases according to the classes of the ICD-10, and the structure of chronic non-communicable respiratory diseases, as well as the frequency of combinations of bronchial asthma, chronic obstructive pulmonary disease, and pulmonary emphysema with the most common concomitant diseases.
Results and discussion. During the epidemic and the subsequent period there was a shift in the comorbidity profile towards predominance of the circulatory system diseases and an increase in their share to almost half of all accompanying diagnoses. The share of chronic non-communicable respiratory diseases in the structure of respiratory diseases has increased significantly, especially in older patients ((82.02% (78.99-85.05) in the SARS-CoV-2 circulation against 23.01% (0.0-52.31) in the pre-epidemic period)), with an increase in the contribution of bronchial asthma and chronic obstructive pulmonary disease. The frequency of combinations of bronchial asthma with disease characterized by high blood pressure, coronary heart disease and allergic rhinitis increased significantly during the circulation of SARS-CoV-2.
Conclusion. COVID-19 is associated with an increase in cardiovascular comorbidities, increased heterogeneity of multimorbidity and more frequent chronic respiratory diseases, which requires a comprehensive multidisciplinary approach to managing such patients.
Keywords: chronic respiratory diseases, bronchial asthma, chronic obstructive pulmonary disease, comorbidity, multimorbidity, coronavirus disease, epidemiology.

Abstract
Introduction. Type 1 diabetes mellitus is one of the leading chronic non‑communicable diseases in childhood and is associated with a high risk of acute and chronic complications, reduced quality of life, and a significant burden on the healthcare system. Accumulated data from international registries and national epidemiological studies indicate a continuing increase in the prevalence of the disease in the pediatric population, with pronounced territorial heterogeneity of the indicators.
Aim of the study was to summarize current concepts of the epidemiological characteristics of type 1 diabetes mellitus in children worldwide and in the Russian Federation; to systematize data on potentially modifiable determinants and associations of the gut and oral microbiota with islet autoimmunity, and to discuss the prospects of risk‑oriented approaches in the pediatric population of a large city using Saint Petersburg as an example.
Materials and methods. A descriptive literature review was performed. The search for publications was conducted in international and domestic databases PubMed, eLIBRARY, Google Scholar, and CyberLeninka. Search queries included combinations of the following keywords: “type 1 diabetes mellitus”, “children”, “epidemiology”, “risk factors”, “gut microbiota”, “oral microbiota”, “islet autoantibodies”, as well as “type 1 diabetes mellitus”, “children”, “epidemiology”, “gut microbiota”, “oral microbiota”, “islet autoantibodies” in English. Sources published mainly between 2019 and 2025 were included, along with selected key earlier works and current regulatory documents. Original clinical and epidemiological studies, data from federal and regional diabetes registries, systematic reviews, meta‑analyses, and clinical guidelines were considered, whereas . educational publications, unpublished materials, and publications not relevant to the topic of the review were excluded.
Results and discussion. The review systematizes current concepts of the global and domestic epidemiology of type 1 diabetes mellitus in children and of potentially modifiable determinants, including characteristics of the gestational and early postnatal periods, nutrition, anthropogenic factors of the urban environment, and infectious agents, as well as associations between the composition of the gut and oral microbiota, islet autoimmunity, and disease manifestation. Prospects for integrating epidemiological, genetic, microbiological, and immunological data into risk‑oriented approaches are discussed.
Conclusion. Accumulated data supports the concept of type 1 diabetes mellitus in children, as a multifactorial disease involving genetic, infectious, behavioral, and microbiological components. The feasibility of conducting comprehensive prospective studies in the pediatric population of large cities in the Russian Federation, particularly Saint Petersburg, is emphasized in order to clarify disease determinants and improve preventive programs.

Abstract
Introduction. Over the past five years, artificial intelligence (AI) has evolved from an experimental technology to a working tool in digital healthcare. In the Russian Federation (RF), this area has been established as a government policy: Presidential Decree No. 490 dated 10.10.2019 [1] and the National AI Development Strategy until 2030 have identified healthcare as a priority area for AI implementation, and the Federal project "Unified Digital Framework" aims to integrate AI modules into the Unified Health Information System. However, the creation of digital ecosystems in domestic healthcare is still difficult due to the fragmentation of information systems and gaps in the regulatory framework.
Aim of the study was to conduct a systematic review of studies on the application of AI technologies in healthcare in the Russian Federation, evaluate the evidence base, and compare domestic diagnostic accuracy rates with international counterparts.
Materials and methods. The search was conducted in the databases eLibrary (RSCI), CyberLeninka, PubMed, Scopus, Web of Science, Cochrane Library for the period 2018–2025. Inclusion criteria: Russian and English publications devoted to the application of AI in clinical practice in the Russian Federation, with original data or systematic analysis.
Results and discussion. Over 962 initially identified works, 42 publications were included in the review; 15 of them were subjected to in-depth analysis. AI is used in radiation diagnostics (Moscow experiment — 1.76 million studies, AUC of mammography 0.937), oncology (colonoscopy — sensitivity of 80.7%), cardiology (gradient boosting outperforms SCORE by 16.9%), primary healthcare (Webiomed PHC — 97% of confirmed conclusions), as well as in dermatooncology, phthisiology, and otorhinolaryngology. Domestic accuracy indicators are comparable to international ones, but the scale of validation is significantly lower than in foreign studies.
Conclusion. Russian AI solutions in radiation diagnostics have moved out of the experimental stage. Outside of radiology, the evidence base is developing more slowly. The fragmentation of IT infrastructure, regulatory gaps, and a lack of labeled datasets are hindering scaling.

Abstract
Introduction. The problem of the spread of the human immunodeficiency virus (hereinafter-HIV) in Russia remains highly relevant, particularly in the context of vulnerable population groups. One of these groups is convicts undergoing supervision in penal enforcement inspections, which are characterized by the intersection of the stigma of crime and the stigma of illness.
Aim of the study was to analyze the attitudes and practices of convicted individuals regarding the HIV and to compare them with other vulnerable groups (sex workers and drug-addicted persons) in order to assess the effectiveness of preventive measures and the level of social awareness of these social groups, as well as to trace the dynamics of the perception of the disease as a socio-cultural phenomenon.
Materials and Methods. The data were obtained through personal interviews with convicted individuals under the supervision of penal enforcement inspectorates in the Moscow (summer 2025, N = 601). Methods of frequency distribution analysis and correlation analysis (Pearson correlation coefficient) were used.
Results and Discussion. The study showed that convicted individuals demonstrate a high level of formal awareness of the routes of transmission of HIV, while their preventive behavior is situational in nature. A low level of external stigmatization of the status of a convicted person was revealed, but high selectivity regarding people living with the HIV : the closer the social distance, the higher the willingness to terminate communication. A paradoxical relationship was recorded: personal acquaintance with infected individuals does not reduce stigma, but rather increases social distance, which distinguishes the group of convicted individuals from other vulnerable groups.
Conclusion. The obtained data confirm the existence of an "awareness paradox" in the group of convicted individuals: awareness exists autonomously from behavior, and personal experience of interaction with infected individuals, in the absence of systemic support,may strengthen prejudices. To overcome the identified contradictions, it is necessary to adapt prevention programs to the specific social norms of key risk groups, shifting the emphasis from purely informational influence to value-oriented approaches and practices.

Abstract
Introduction. Ensuring the quality and safety of medical activities is a priority task of healthcare. In the context of digital transformation, technologies for objective control of personnel's communicative competencies are becoming particularly relevant, but the potential of audio fixation in medical practice has not been sufficiently studied.
Aim of the study was to evaluate the importance of audio monitoring technologies in improving the effectiveness of communication in the doctor-patient interaction model for managing the quality and safety of medical care.
Materials and methods. The study was performed on the basis of the European Medical medical center “UMMC-Health” in 2024-2026. Audio monitoring was carried out using VOCA-TECH technology (individual audio tags and a speech analytics system based on artificial intelligence). At the first stage, 11 109 recordings from 10 audio pages were analyzed. The main analysis included 6,732 audio recordings of medical consultations at the polyclinic, distributed over two periods: before and after the implementation of corrective measures (trainings, feedback). Communication was assessed using 11 metrics integrated with the Calgary-Cambridge model.
Results. A statistically significant improvement was found in 10 out of 11 monitored indicators. The most pronounced dynamics was recorded at the "Beginning of the consultation" stage: the frequency of greetings increased from 68.5% to 96.0% (p<0.001). Patient identification, representation by name and position, identification of needs, provision of recommendations, farewell, as well as cross-cutting metrics of politeness (from 95.3% to 96.3%; p=0.041) and empathy (from 52.3% to 58.5%; p<0.001) significantly improved. The "greeting bundle" metric has not changed (p=0.428).
Conclusion. Audio recording technologies integrated with methodologically sound communication models and regular feedback are an effective tool for improving the quality of interaction in the doctor–patient system and may be considered as a promising component of the digital infrastructure of a medical organization.

Abstract
Introduction. In the context of the demographic crisis, the study of morbidity patterns in the working-age population, considering expert predictions regarding the negative impact of the novel coronavirus infection (COVID-19) on public health, is an urgent task for specialists in occupational medicine and public health.
Aim of the study was to conduct a comparative assessment of morbidity rates in the adult population of the Republic of Bashkortostan in the pre-pandemic period (2011–2019) and in the post-pandemic period of 2023.
Materials and methods. Primary morbidity (hereinafter-PM) and overall morbidity (hereinafter-OM) rates were calculated for the working-age population in the post-pandemic period of COVID-19. Mean values (M) for 2011–2019 were estimated, as well as growth rates of PM, OM, and the chronicity rate (hereinafter-CR) in 2023 compared to the pre-COVID period. To assess the statistical significance of differences between the 2023 indicators and the pre-COVID period, confidence intervals (hereinafter-CI) were developed for the general mean value for 2015–2019. To evaluate differences in the structure of PM and OM between the pre- and post-COVID periods, the Newcombe CI for the difference in binomial proportions was used.
Results. In 2023, a statistically significant increase in the level of PM and OM rates was observed for all disease classes compared to the pre-pandemic period, accompanied by a decrease in CR. The changes in PM, OM, and CR varied across different disease classes. The highest growth rates in morbidity were recorded for respiratory diseases. The assessment of the nosological structure of PM and OM in the pre- and post-pandemic periods revealed statistically significant differences in the proportions of individual disease classes.
Conclusion. The identified post-pandemic changes in morbidity rates among the working-age population of the Republic of Bashkortostan should be taken into account within the framework of the territorial program of state guarantees for free medical care and regional public health promotion programs. Particular attention in the implementation of preventive programs should be paid to disease types that showed a statistically significant increase in morbidity and chronicity rates.
Keywords: working-age population, primary morbidity, overall morbidity, chronicity rate, morbidity structure.

Abstract
Introduction. The Ministry of Health of the Russian Federation has designed a Portal for Continuing Medical and Pharmaceutical Education (hereinafter-Portal), which allows employees to form an individual educational trajectory, and employers to adjust and monitor its implementation.
Aim of the study was to analyze the involvement of healthcare professionals in the system of continuing medical and pharmaceutical education via the Portal, using a large federal multidisciplinary medical and research organization (hereinafter- Organization) as a case study.
Materials and Methods. The first stage of the study (2022) involved the collection and analysis of data on the completion of educational components by the Organization's employees via the Portal. The second stage (2023–2024) – a survey of healthcare professionals with secondary and higher medical education. The third stage (2025) comprised a comparative analysis of the dynamics in educational component completion. Differences were considered statistically significant at p < 0.05.
Results. It was found that educational activity is minimal during the first three years of the five-year cycle, reaching its peak in the fourth and fifth years (p < 0.05). Nursing and paramedical staff (healthcare professionals with secondary medical education) are characterized by infrequent use of the Portal, low proficiency in its functional features, low participation in educational events, and a lower willingness to pay for continuing education from their own funds. Physicians more frequently prefer the traditional face-to-face training system once every five years. In 2025, there were 1.46 ± 0.68 five-year cycles per employee, which is lower than in 2022 (p = 0.006). A significant (14.3 times) increase was noted in the average number of credit units earned for completing interactive educational modules, as well as for continuing education programs (a 1.7-fold increase). More than 144 credit units for continuing education programs were earned in 17.5% of five-year cycles, which is 2.1 times higher than in 2022 (with a maximum of 1008 credit units).
Conclusion. A significant increase in activity regarding the completion of educational components was identified, particularly in interactive educational modules. It is important to note the excessive completion of continuing education programs, leading to the inefficient use of resources.

Abstract
Introduction. Obesity is recognized as a chronic disease; however, in clinical practice it is frequently not verified as an independent diagnosis, which limits the timely detection of comorbid conditions and initiation of preventive interventions.
Aim of the study was to assess the prevalence of undiagnosed obesity and characterize its clinical and nutritional profile in a large digital cohort.
Materials and methods. A retrospective case–control study was conducted using data from a digital platform (2022–2025). The cohort included 3,267 adults,dividing in the following groups: hidden obesity (body mass index ≥30 kg/m² without diagnosis, n=636), diagnosed obesity (n=31), control (body mass index 18.5–24.9 kg/m², n=1,629). Statistics: Pearson’s chi-square test, Welch’s t-test, Mann–Whitney U-test.
Results and discussion. Actual obesity prevalence was 20.3%, while the diagnosis was recorded in was only 0.9%. Hidden obesity accounted for 19.5% of the cohort (95% confidence interval: 18.1–20.9%). Hypertension and diabetes rates in the hidden obesity group were 3.6 and 3.9 times lower than in the diagnosed group (significance level <0.001), indicating a diagnostic trigger effect. Patients with hidden obesity consumed significantly less energy and protein per kilogram of body weight (significance level <0.001) but had higher absolute caloric intake and elevated sodium and cholesterol consumption.
Conclusion. Hidden obesity affects every fifth adult and is associated with systematic underdiagnosis of metabolic risks. Implementation of automated body mass index screening and algorithmic diagnosis verification in primary care is essential for early preventive interventions.

Abstract
Introduction. Mechanization of underground mining did not have an expected positive impact on occupational morbidity among miners in the Murmansk region.
Aim of the study was to analyze the occupational health characteristics of various mining underground equipment operators in the Murmansk region.
Materials and Methods. The study examined the working conditions and data on 2,119 non-occupational and 370 occupational diseases in five groups of various mining equipment operators (n=784). The observation period was from 2003 to 2023.
Results. The working conditions of mining equipment operators corresponded to classes 3.2-3.3. An analysis of data from 2003 to 2023 revealed the specific features of the structure of non-professional and professional pathologies among miners. In all five groups, musculoskeletal pathologies accounted for the largest share of non-occupational disease classes, with a higher prevalence among drilling and vibratory transport unit operators than among underground self-propelled machine operators (p=0.002 and p<0.001) and electric locomotive operators (p=0.046 and p=0.019).The most common cause of occupational diseases was increased workload: from 41.2% among underground self-propelled machine operators to 71.4% in drillers. The proportion of workers, who developed occupational diseases over 21 years-period, ranged from 18.9% among electric locomotive drivers to 37.8% in vibratory transport unit operators. In the structure of occupational diseases in drillers, loader-dump machine operators, and vibratory transport unit operators, the largest shares belonged to musculoskeletal diseases (68.2%), effects of vibration (35.3%), and sensorineural hearing loss (39.1%), respectively. The morbidity rate in miners exceeded the national average for underground ore mining by 1.40-2.76 times.
Conclusion. In 2003–2023, operators of modern mining equipment continued to experience hazardous working conditions and there was no reduction in the number of workers with primary occupational pathology or in the number of occupational diseases. In order to improve the effectiveness of preventive measures, it is advisable to implement them taking into account the established health disorders in different groups of operators.

Abstract
Introduction. The analytical review of literature presents information concerning modern views on predisposing, directly causal and provoking factors of development, as well as triggering, supporting pathogenetic mechanisms of chronic allergic inflammation in IgE-mediated atopic dermatitis in adolescence, since one of the actual and unresolved problems of pediatrics remains insufficient effectiveness of existing therapeutic approaches and methods of prevention in atopic dermatitis. For many decades, one of the most pressing and unresolved problems in pediatrics has been the insufficient effectiveness of existing therapeutic approaches and prevention methods for atopic dermatitis. This pathological process occurs in all age groups of childhood, as well as in adolescents. The article also discusses the principles of selecting therapy for adolescents with this pathological process.
Conclusion. In understanding the patterns of development of IgE-mediated atopic dermatitis, it is important to study the role of vitamin D in the pathogenetic mechanisms of skin barrier damage and, separately, the development of itching sensations, which are associated with the failure of structural and antimicrobial proteins in the epidermis and the initiation of the above-described immune reactions directly in the skin, as well as with central and peripheral neurogenic effects on the skin. Conducting studies in adolescents with IgE-mediated atopic dermatitis could potentially establish a link between vitamin D content and central and peripheral neurogenic activity. This information could provide a basis for developing therapeutic approaches in adolescents with this pathological condition that aim to modulate neurogenic effects on the skin through vitamin D.

Abstract
Introduction. Despite the evolution and high efficiency of rotator cuff tendon repair techniques, a high frequency of recurrent ruptures and non-accretions remains. reruptures. There is no consensus regarding the choice of repair technique.
Aim of the study was to analyse the mid-term functional and structural results of arthroscopic transosseous suturing using the free-hand technique in patients with medium sized rotator cuff tears.
Materials and Methods. A prospective observational cohort cross-sectional study of rotator cuff integrity assessed by MRI performed 12 months after arthroscopic transosseous repair in 168 patients with tears ranging from 2 to 4 cm in anterior-to-posterior size, as well as their functional outcomes using the ASES, Constant, and VAS scales, measuring range of motion deficits and assessing the scapulohumeral rhythm after 24 months. The data were analyzed taking into account patient characteristics, bone mineral density of the greater tubercle of the humerus, the severity of fatty infiltration of the supraspinatus muscle, osteoarthritis and tear size.
Results. Complete healing of the supraspinatus tendon occurred in 143 patients (85.1%), absence of gap but tendon thinning occurred in 14 patients (8.3%), and recurrent rupture or non-healing occurred in 11 patients (6.5%). Statistically significant risk factors for non-healing were tear size, fatty infiltration of the supraspinatus muscle and decrease of acromiohumeral interval. No clinical or EMG signs of axillary nerve injury were registered. Excellent and good functional scale scores were obtained in 146 patients (86.9%). Deterioration of functional results in the remaining cases was associated with suture failure, osteoarthritis progression, pain syndrome and limited shoulder motion.
Conclusion. Arthroscopic transosseous repair using the "freehand" technique is an effective treatment for patients with full-thickness rotator cuff tendon tears ranging in size from 2 to 4 cm. Risk factors for non-healing include tear size, fatty infiltration of the muscle tissue and persistent superior migration of the humeral head.

Abstract
Introduction. Multimorbidity and comorbid conditions play a crucial role in the formation of morbidity and mortality in chronic respiratory diseases and are significantly modified by new coronavirus infection.
Aim of the study was to analyze the epidemiological profile of multimorbidity and comorbid conditions in chronic respiratory diseases in hospitalized patients in the context of the spread of COVID-19.
Materials and methods. A retrospective epidemiological analysis of data from the medical information system of a multidisciplinary hospital in Saint Petersburg was performed for the period 2017-2025. The study was conducted in three periods: pre-epidemic (2017-2019), epidemic (2020-2022) and period of declining epidemic intensity (2023-2025). The study evaluated the structure of concomitant diseases according to the classes of the ICD-10, and the structure of chronic non-communicable respiratory diseases, as well as the frequency of combinations of bronchial asthma, chronic obstructive pulmonary disease, and pulmonary emphysema with the most common concomitant diseases.
Results and discussion. During the epidemic and the subsequent period there was a shift in the comorbidity profile towards predominance of the circulatory system diseases and an increase in their share to almost half of all accompanying diagnoses. The share of chronic non-communicable respiratory diseases in the structure of respiratory diseases has increased significantly, especially in older patients ((82.02% (78.99-85.05) in the SARS-CoV-2 circulation against 23.01% (0.0-52.31) in the pre-epidemic period)), with an increase in the contribution of bronchial asthma and chronic obstructive pulmonary disease. The frequency of combinations of bronchial asthma with disease characterized by high blood pressure, coronary heart disease and allergic rhinitis increased significantly during the circulation of SARS-CoV-2.
Conclusion. COVID-19 is associated with an increase in cardiovascular comorbidities, increased heterogeneity of multimorbidity and more frequent chronic respiratory diseases, which requires a comprehensive multidisciplinary approach to managing such patients.
Keywords: chronic respiratory diseases, bronchial asthma, chronic obstructive pulmonary disease, comorbidity, multimorbidity, coronavirus disease, epidemiology.

Abstract
Introduction. Type 1 diabetes mellitus is one of the leading chronic non‑communicable diseases in childhood and is associated with a high risk of acute and chronic complications, reduced quality of life, and a significant burden on the healthcare system. Accumulated data from international registries and national epidemiological studies indicate a continuing increase in the prevalence of the disease in the pediatric population, with pronounced territorial heterogeneity of the indicators.
Aim of the study was to summarize current concepts of the epidemiological characteristics of type 1 diabetes mellitus in children worldwide and in the Russian Federation; to systematize data on potentially modifiable determinants and associations of the gut and oral microbiota with islet autoimmunity, and to discuss the prospects of risk‑oriented approaches in the pediatric population of a large city using Saint Petersburg as an example.
Materials and methods. A descriptive literature review was performed. The search for publications was conducted in international and domestic databases PubMed, eLIBRARY, Google Scholar, and CyberLeninka. Search queries included combinations of the following keywords: “type 1 diabetes mellitus”, “children”, “epidemiology”, “risk factors”, “gut microbiota”, “oral microbiota”, “islet autoantibodies”, as well as “type 1 diabetes mellitus”, “children”, “epidemiology”, “gut microbiota”, “oral microbiota”, “islet autoantibodies” in English. Sources published mainly between 2019 and 2025 were included, along with selected key earlier works and current regulatory documents. Original clinical and epidemiological studies, data from federal and regional diabetes registries, systematic reviews, meta‑analyses, and clinical guidelines were considered, whereas . educational publications, unpublished materials, and publications not relevant to the topic of the review were excluded.
Results and discussion. The review systematizes current concepts of the global and domestic epidemiology of type 1 diabetes mellitus in children and of potentially modifiable determinants, including characteristics of the gestational and early postnatal periods, nutrition, anthropogenic factors of the urban environment, and infectious agents, as well as associations between the composition of the gut and oral microbiota, islet autoimmunity, and disease manifestation. Prospects for integrating epidemiological, genetic, microbiological, and immunological data into risk‑oriented approaches are discussed.
Conclusion. Accumulated data supports the concept of type 1 diabetes mellitus in children, as a multifactorial disease involving genetic, infectious, behavioral, and microbiological components. The feasibility of conducting comprehensive prospective studies in the pediatric population of large cities in the Russian Federation, particularly Saint Petersburg, is emphasized in order to clarify disease determinants and improve preventive programs.

Abstract
Introduction. Over the past five years, artificial intelligence (AI) has evolved from an experimental technology to a working tool in digital healthcare. In the Russian Federation (RF), this area has been established as a government policy: Presidential Decree No. 490 dated 10.10.2019 [1] and the National AI Development Strategy until 2030 have identified healthcare as a priority area for AI implementation, and the Federal project "Unified Digital Framework" aims to integrate AI modules into the Unified Health Information System. However, the creation of digital ecosystems in domestic healthcare is still difficult due to the fragmentation of information systems and gaps in the regulatory framework.
Aim of the study was to conduct a systematic review of studies on the application of AI technologies in healthcare in the Russian Federation, evaluate the evidence base, and compare domestic diagnostic accuracy rates with international counterparts.
Materials and methods. The search was conducted in the databases eLibrary (RSCI), CyberLeninka, PubMed, Scopus, Web of Science, Cochrane Library for the period 2018–2025. Inclusion criteria: Russian and English publications devoted to the application of AI in clinical practice in the Russian Federation, with original data or systematic analysis.
Results and discussion. Over 962 initially identified works, 42 publications were included in the review; 15 of them were subjected to in-depth analysis. AI is used in radiation diagnostics (Moscow experiment — 1.76 million studies, AUC of mammography 0.937), oncology (colonoscopy — sensitivity of 80.7%), cardiology (gradient boosting outperforms SCORE by 16.9%), primary healthcare (Webiomed PHC — 97% of confirmed conclusions), as well as in dermatooncology, phthisiology, and otorhinolaryngology. Domestic accuracy indicators are comparable to international ones, but the scale of validation is significantly lower than in foreign studies.
Conclusion. Russian AI solutions in radiation diagnostics have moved out of the experimental stage. Outside of radiology, the evidence base is developing more slowly. The fragmentation of IT infrastructure, regulatory gaps, and a lack of labeled datasets are hindering scaling.

Abstract
Introduction. The problem of the spread of the human immunodeficiency virus (hereinafter-HIV) in Russia remains highly relevant, particularly in the context of vulnerable population groups. One of these groups is convicts undergoing supervision in penal enforcement inspections, which are characterized by the intersection of the stigma of crime and the stigma of illness.
Aim of the study was to analyze the attitudes and practices of convicted individuals regarding the HIV and to compare them with other vulnerable groups (sex workers and drug-addicted persons) in order to assess the effectiveness of preventive measures and the level of social awareness of these social groups, as well as to trace the dynamics of the perception of the disease as a socio-cultural phenomenon.
Materials and Methods. The data were obtained through personal interviews with convicted individuals under the supervision of penal enforcement inspectorates in the Moscow (summer 2025, N = 601). Methods of frequency distribution analysis and correlation analysis (Pearson correlation coefficient) were used.
Results and Discussion. The study showed that convicted individuals demonstrate a high level of formal awareness of the routes of transmission of HIV, while their preventive behavior is situational in nature. A low level of external stigmatization of the status of a convicted person was revealed, but high selectivity regarding people living with the HIV : the closer the social distance, the higher the willingness to terminate communication. A paradoxical relationship was recorded: personal acquaintance with infected individuals does not reduce stigma, but rather increases social distance, which distinguishes the group of convicted individuals from other vulnerable groups.
Conclusion. The obtained data confirm the existence of an "awareness paradox" in the group of convicted individuals: awareness exists autonomously from behavior, and personal experience of interaction with infected individuals, in the absence of systemic support,may strengthen prejudices. To overcome the identified contradictions, it is necessary to adapt prevention programs to the specific social norms of key risk groups, shifting the emphasis from purely informational influence to value-oriented approaches and practices.

Abstract
Introduction. Ensuring the quality and safety of medical activities is a priority task of healthcare. In the context of digital transformation, technologies for objective control of personnel's communicative competencies are becoming particularly relevant, but the potential of audio fixation in medical practice has not been sufficiently studied.
Aim of the study was to evaluate the importance of audio monitoring technologies in improving the effectiveness of communication in the doctor-patient interaction model for managing the quality and safety of medical care.
Materials and methods. The study was performed on the basis of the European Medical medical center “UMMC-Health” in 2024-2026. Audio monitoring was carried out using VOCA-TECH technology (individual audio tags and a speech analytics system based on artificial intelligence). At the first stage, 11 109 recordings from 10 audio pages were analyzed. The main analysis included 6,732 audio recordings of medical consultations at the polyclinic, distributed over two periods: before and after the implementation of corrective measures (trainings, feedback). Communication was assessed using 11 metrics integrated with the Calgary-Cambridge model.
Results. A statistically significant improvement was found in 10 out of 11 monitored indicators. The most pronounced dynamics was recorded at the "Beginning of the consultation" stage: the frequency of greetings increased from 68.5% to 96.0% (p<0.001). Patient identification, representation by name and position, identification of needs, provision of recommendations, farewell, as well as cross-cutting metrics of politeness (from 95.3% to 96.3%; p=0.041) and empathy (from 52.3% to 58.5%; p<0.001) significantly improved. The "greeting bundle" metric has not changed (p=0.428).
Conclusion. Audio recording technologies integrated with methodologically sound communication models and regular feedback are an effective tool for improving the quality of interaction in the doctor–patient system and may be considered as a promising component of the digital infrastructure of a medical organization.

Abstract
Introduction. In the context of the demographic crisis, the study of morbidity patterns in the working-age population, considering expert predictions regarding the negative impact of the novel coronavirus infection (COVID-19) on public health, is an urgent task for specialists in occupational medicine and public health.
Aim of the study was to conduct a comparative assessment of morbidity rates in the adult population of the Republic of Bashkortostan in the pre-pandemic period (2011–2019) and in the post-pandemic period of 2023.
Materials and methods. Primary morbidity (hereinafter-PM) and overall morbidity (hereinafter-OM) rates were calculated for the working-age population in the post-pandemic period of COVID-19. Mean values (M) for 2011–2019 were estimated, as well as growth rates of PM, OM, and the chronicity rate (hereinafter-CR) in 2023 compared to the pre-COVID period. To assess the statistical significance of differences between the 2023 indicators and the pre-COVID period, confidence intervals (hereinafter-CI) were developed for the general mean value for 2015–2019. To evaluate differences in the structure of PM and OM between the pre- and post-COVID periods, the Newcombe CI for the difference in binomial proportions was used.
Results. In 2023, a statistically significant increase in the level of PM and OM rates was observed for all disease classes compared to the pre-pandemic period, accompanied by a decrease in CR. The changes in PM, OM, and CR varied across different disease classes. The highest growth rates in morbidity were recorded for respiratory diseases. The assessment of the nosological structure of PM and OM in the pre- and post-pandemic periods revealed statistically significant differences in the proportions of individual disease classes.
Conclusion. The identified post-pandemic changes in morbidity rates among the working-age population of the Republic of Bashkortostan should be taken into account within the framework of the territorial program of state guarantees for free medical care and regional public health promotion programs. Particular attention in the implementation of preventive programs should be paid to disease types that showed a statistically significant increase in morbidity and chronicity rates.
Keywords: working-age population, primary morbidity, overall morbidity, chronicity rate, morbidity structure.

Abstract
Introduction. The Ministry of Health of the Russian Federation has designed a Portal for Continuing Medical and Pharmaceutical Education (hereinafter-Portal), which allows employees to form an individual educational trajectory, and employers to adjust and monitor its implementation.
Aim of the study was to analyze the involvement of healthcare professionals in the system of continuing medical and pharmaceutical education via the Portal, using a large federal multidisciplinary medical and research organization (hereinafter- Organization) as a case study.
Materials and Methods. The first stage of the study (2022) involved the collection and analysis of data on the completion of educational components by the Organization's employees via the Portal. The second stage (2023–2024) – a survey of healthcare professionals with secondary and higher medical education. The third stage (2025) comprised a comparative analysis of the dynamics in educational component completion. Differences were considered statistically significant at p < 0.05.
Results. It was found that educational activity is minimal during the first three years of the five-year cycle, reaching its peak in the fourth and fifth years (p < 0.05). Nursing and paramedical staff (healthcare professionals with secondary medical education) are characterized by infrequent use of the Portal, low proficiency in its functional features, low participation in educational events, and a lower willingness to pay for continuing education from their own funds. Physicians more frequently prefer the traditional face-to-face training system once every five years. In 2025, there were 1.46 ± 0.68 five-year cycles per employee, which is lower than in 2022 (p = 0.006). A significant (14.3 times) increase was noted in the average number of credit units earned for completing interactive educational modules, as well as for continuing education programs (a 1.7-fold increase). More than 144 credit units for continuing education programs were earned in 17.5% of five-year cycles, which is 2.1 times higher than in 2022 (with a maximum of 1008 credit units).
Conclusion. A significant increase in activity regarding the completion of educational components was identified, particularly in interactive educational modules. It is important to note the excessive completion of continuing education programs, leading to the inefficient use of resources.
