Nitric oxide can activate neutrophils and macrophages, facilitate the synthesis of collagen, which allows significantly accelerating the regeneration of traumatized tissues. We studied the effects of nitric oxide-containing gas flow generated by plasma-chemical device “Plason” in a rat model of full-thickness wounds. Histological and morphometric analyses revealed that Plason treated wounds expressed significantly fewer signs of inflammation and contained a more mature granulation tissue on day 4 after the operation. Considering the results of the experimental study, we applied the Plason device in sports medicine for the treatment of lower limb bruises of 34 professional soccer players. Athletes were asked to assess the intensity of pain with the Visual Analogue Scale. Girths of their lower limbs were measured over the course of rehabilitation. Nitric oxide therapy of full-thickness wounds inhibited inflammation and accelerated the regeneration of skin and muscle tissues. Compared with the control, we observed a significant reduction in pain syndrome on days 2–7 after injuries, edema, and hematoma, and shortened treatment duration. This pilot study indicates that the use of nitric oxide is a promising treatment method for sports injuries.

A Metabolic Activity Recovery of the Intestinal Microbiota in the Patients with Bronchial Asthma: Goals. We assessed the possibilities of correcting the short-chain fatty acids (SCFA) content and profiles in feces of patients with bronchial asthma. Background. It was established that the high biological diversity of intestinal microorganisms promotes the needed SCFAs production, which induces immune regulatory pathways and contributes to the anti-inflammatory response. Study. A group of 30 patients with allergic bronchial asthma (BA) were investigated in our study. All of the patients were tested for the presence of SIBO by the SCFA spectrum determination. For the SIBO treatment, 10 patients from the studied group were prescribed Rifaximinum with the 200 mg dose at 3 times a day for a week; the other 10 patients were prescribed Rifaximinum at the same dose, followed by the administration of the Lactobalance probiotic in capsules at 3 times a day for a month. A month probiotic course was assigned to the remaining 10 patients without SIBO, as part of the BA complex therapy. The SCFA studies were immediately carried out for all of the patients after the 1 month probiotic therapy course. Results. A normalization of the SCFA spectrum and anaerobic index for all of the studied patients were noted. Upon taking the probiotics, it was revealed in the patients without SIBO that the total content of fatty acids ( ), acetic and butyric acid ( ) had increased. The Rifaximinum course, followed by administration of the probiotics led to a decrease of the relative amount of isoacids and ratio of isoacids/acids in the studied patients as compared to the patients who had received Rifaximinum for the SIBO treatment only ( ). Conclusion. The obtained results demonstrate a potential opportunity of the drug influence on the active bacterial metabolites composition and amount in the intestinal biotope; as it was confirmed by the restoration of the intestinal microbiocenosis and microorganism habitat.

INTRODUCTION. Vitiligo is an acquired skin disease characterized by loss of pigmentation with the destruction of epidermal melanocytes. The etiology and pathogenesis of this disease are still poorly understood. The course of vitiligo affects the patient's quality of life, his psychological state and self-esteem. In this regard, there is a need to develop new and promising methods aimed at stimulating and modulating the reparative processes of damaged tissues. AIM. To review the scientific literature on traditional therapy and new approaches to the treatment of vitiligo. MATERIALS AND METHODS. The literature review was conducted using the RINTS, PubMed and ScienceDirect databases. Query dates — March–July 2024, query depth — 1964–2024. MAIN CONTENT OF THE REVIEW. Conservative treatment methods are aimed at inhibiting the pathological process, preventing the appearance of new spots and reducing the cosmetic defect. Thus, patients are prescribed topical and systemic glucocorticosteroids, calcineurin inhibitors, immunosuppressants, phototherapy both in monotherapy and in combination. In recent years, technologies based on transplantation of autologous suspension of regenerative skin cells have been considered the most promising. CONCLUSION. Innovative methods of regenerative medicine are a good alternative to traditional treatments for patients with stable vitiligo, especially for those who do not respond to standard drug therapy.

Background: Many authors have noted the lack of knowledge on the causal relationship between the degree of physical activity, the dynamics, and outcomes of diseases, as well as the influence of sports history on the rehabilitation potential of former athletes. Purpose: Assessment of the functional state of the cardiovascular system according to the indicators of electrocardiography, polycardiography, echocardiography and the level of physical performance in masters athletes. Patients and Methods: The study included a main group consisting of 100 athletes, who had undergone electrocardiography, poly-electrocardiography, ultrasound echocardiography, heart rate and blood pressure measurement to determine their level of physical performance. The subjects were then divided into 2 groups. The first group included 75 people who continue to be active in regular sports activities. The second group consisted of 25 people who completely stopped training or had only occasional, unsystematic physical activities. A control group of 31 people, consisting of people of the same age who had not been involved in sports earlier, was examined according to the same program. Results: The data obtained by us show that sports activities do contribute to the increasing stability of the body and maximize the deployment of the capabilities of the circulatory system, including their long-term preservation in masters athletic. Athletes who have stopped training have signs of age-related changes in the heart and blood vessels, which seem to be more frequent and earlier than those who continue training. A higher degree of myocardial contractility (in 90.67% of cases) can also be seen in the main group. Conclusion: Masters athletes and those who stopped training after completing their sports career, should have notably thorough medical supervision and undergo regular annual in-depth examination.

Prader — Willi syndrome (PWS) is a rate multisystem disease caused by a developmental disorder of the nervous system. The syndrome is associated with an imprinting defect, i.e. lack of expression of paternal genes on chromosome 15 q11.2q13.1. This genetic defect leads to cognitive and behavioral disorders; hypothalamic dysfunction; endocrine, cardiovascular, musculoskeletal, respiratory, and other disorders. PWS is the most frequent cause of hereditary obesity. In turn, the obesity causes the obesity-hypoventilation syndrome and respiratory failure.The aim of this article was to describe a clinical case of 28-year-old female who presented with acute hypercapnic respiratory failure.Conclusion. The patient was treated with respiratory support (non-invasive ventilation). The timely diagnosis and treatment of respiratory failure is important for the outcome as it can improve the patient’s quality of life and the life expectancy.

Purpose: The purpose of this study is to examine the prevalence of workplace exposure, behavior, and individual health conditions, along with resulting medical activity among locomotive crew members depending on their place of work. Patients and methods: Participants included 5585 train drivers and 3723 train drivers’ assistants (7% of the total train operators in the Russian Federation). Measured height and weight were used to calculate body mass index (BMI), and waist circumference, pulse rate, and blood pressure were also measured. The risk assessment was conducted using the STEPS tool. The level of commitment to a Healthy Lifestyle was assessed based on World Health Organization recommendations. Occupational risk factors were surveyed. Morbidity was analyzed over the past year. Results: The lowest frequency of work exposure risk factors was found for employees of the Trans-Baikal railway; the highest was among Krasnoyarsk, North, and South-East. The participants from the Far East and October Railways had the lowest self-reported frequency of behavioral risk factors. The participants from the Eastern Siberian, October, and Southern Urals railways had the lowest occurrence of individual health conditions. The participants from the East Siberian, Far East, Kuibyshev, and Sverdlovsk railways were the least likely to visit their doctor, take temporary disability leave, or be hospitalized. The total assessed Healthy Lifestyle commitment index was higher for participants from the Far Eastern and Southern Urals railways. The participants from the Moscow and October railways were the least committed to a Healthy Lifestyle. Conclusions: Significant differences exist between risk factors and Healthy Lifestyle commitment between railways. Future research should examine changes due to a new corporate health program introduced in 2020.
