Background: In recent years, many countries have actively implemented programs and strategies to promote physical education and sports. Despite these efforts, the increase in physical activity has been accompanied by a significant rise in muscle and tendon-ligament injuries, with Achilles tendon rupture being the most prevalent, accounting for 47 % of such injuries. This review aims to summarize all significant factors determining the predisposition of the Achilles tendon to rupture, to develop effective personalized prevention measures. Objective: To identify and evaluate the risk factors contributing to Achilles tendon rupture and to develop strategies for personalized prevention. Methods: This review utilized data from several databases, including Elsevier, Global Health, PubMed-NCBI, Embase, Medline, Scopus, ResearchGate, RSCI, Cochrane Library, Google Scholar, eLibrary.ru, and CyberLeninka. Both non-modifiable and modifiable risk factors for Achilles tendon injuries and ruptures were analyzed. Results: The analysis identified several non-modifiable risk factors, such as genetic predisposition, anatomical and functional features of the Achilles tendon, sex, and age. These factors should be considered when selecting sports activities and designing training programs. Modifiable risk factors included imbalanced nutrition, improper exercise regimens, and inadequate monitoring of Achilles tendon conditions in athletes. Early treatment of musculoskeletal injuries, Achilles tendon diseases, foot deformities, and metabolic disorders is crucial. Long-term drug use and its risk assessment were also highlighted as important considerations. Furthermore, recent clinical advancements in both conventional and surgical methods to treat Achilles tendon injuries were described. The efficacy of these therapies in enhancing functional outcomes in individuals with Achilles injuries was compared. Advancements in cell-based and scaffold-based therapies aimed at enhancing cell regeneration and repairing Achilles injuries were also discussed. Discussion: The combination of several established factors significantly increases the risk of Achilles tendon rupture. Addressing these factors through personalized prevention strategies can effectively reduce the incidence of these injuries. Proper nutrition, regular monitoring, timely treatment, and the correction of metabolic disorders are essential components of a comprehensive prevention plan. Conclusion: Early identification of Achilles tendon risk factors allows for the timely development of effective personalized prevention strategies. These measures can contribute significantly to public health preservation by reducing the incidence of Achilles tendon ruptures associated with physical activity and sports. Continued research and clinical advancements in treatment methods will further enhance the ability to prevent and manage Achilles tendon injuries. The translational potential of this article: This study identifies key modifiable and non-modifiable risk factors for Achilles tendon injuries, paving the way for personalized prevention strategies. Emphasizing nutrition, exercise, and early treatment of musculoskeletal issues, along with advancements in cell-based therapies, offers promising avenues for improving recovery and outcomes. These findings can guide clinical practices in prevention and rehabilitation, ultimately reducing Achilles injuries and enhancing public health.

A necessary condition for public health maintenance is regular physical activity. A significant increase in the number of musculoskeletal injuries, occurring during physical education and sport activities, actualizes the development of effective measures for their prevention. Early diagnosis of injury predisposition, based on identification of connective tissue dysplasia indicators specific for different age periods, is of particular importance for the prevention of such injuries. The study, performed in accordance to STROBE guidelines, included 78 persons separated into two age subgroups: Group 1 (age 22–35) and Group 2 (age 36–47). Morphometric signs of connective tissue dysplasia and clinical symptoms associated with predisposition to chronic injury were assessed. For persons in Group 1, these indicators included: asthenic body type, joint hypermobility, thin elastic skin, keloid scars, and soft auricles. For the second group: kyphosis, skin hyperpigmentation above the spine, flatfeet, valgus installation, rectus muscles diastasis, atrophic striae, recurrent hernias, and lower-limb varicosity. Universal pathognomonic indicators, such as “crunching” in the temporomandibular joint, gothic palate, altered chest shape, scoliosis, and X- and O-shaped legs are significant at any age. The established pathognomonic indicators will promote early diagnosis of injury predisposition help, and develop effective measures of their prevention and public health preservation during physical activity.

To identify factors affecting the mental and physical health of first-year medical students during the period of rapid SARS-COV-2 spread in the COVID-19 pandemic to develop effective strategies for managing student well-being and education quality during global pandemics. 656 first-year students of Sechenov University aged 17 to 23 years (17.91 ± 1.01 years) were included in an online anonymous survey. The study consisted of two assessment phases: in traditional training in September-December 2021 and in distance learning in January-March 2022. The State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory, the Cantril Self-Anchoring Scale, and an original questionnaire were used for evaluation. During the rapid COVID-19 spread in COVID-19 pandemic, most first-year medical students had a high level of reactive anxiety, accompanied by depressive disorders and vegetative-somatic manifestations that significantly reduced their adaptive potential, life quality and academic performance. All first-year students regardless of age were shown to be sensitive to stressful situation. The females demonstrated more pronounced psycho-vegetative changes compared to the males. Students of medical, pediatrics and medico-preventive faculties reacted more strongly to the current situation than students of dental and pharmaceutical faculties. The identified changes in the psycho-vegetative student status were associated, first of all, with the difficult sanitary-epidemiological SARS-COV-2 situation and related financial problems. Students considered the transition to distance learning to be the most important support measures. Temporary transition to distance learning led to the significant decrease in the anxiety level, correction of depressive and vegetative manifestations, and significant increase in the life quality that was of great importance for the education quality. Significant student support measures during COVID-19 pandemic were also financial, psychological and informational assistance. The obtained results made it possible to develop the effective strategies for managing student health and education quality during global pandemics.

Aim. The article deals with establishing the character of the correlations between the somatometrical features and morphological signs of connective tissue dysplasia in persons with frequent post exercise structural and functional disorders of the locomotor apparatus. This is required for creating treatment and disease preventive measures and recommendations to choose an adequate physical activity. Materials and methods. A comprehensive medical and anthropological examination of 48 people aged from 18 to 47 years (mean age 36.38 ± 6.02 years) with frequent post exercise structural and functional disorders of the locomotor apparatus was carried out. A questionnaire was developed to assess the status of their connective tissue. The control group consisted of 36 apparently healthy people aged 18.85 ± 0.56 years. Statistical processing of the data obtained was performed using Microsoft Excel 2010. Results. All patients with frequent post exercise structural and functional disorders of the locomotor apparatus had connective tissue dysplasia of moderate and severe degree, the total score of which was 49.44 ± 13.1. The analysis of the frequency of connective tissue dysplasia morphological signs occurrence depending on their diagnostic significance, made it possible to establish the pathognomonic predictors of high susceptibility to frequent disorders of the locomotor apparatus. Conclusion. Early diagnostics of frequent disorders of the locomotor apparatus will contribute to timely preventive measures in terms of physical load and a corresponding rehabilitation for eliminating the deve­lopment of the main disorder.
