Authors: Nair Nikhil , Chakraborty Ronith , Mahajan Zubin , Sharma Aditya , K. Sethi Sidharth , Raina Rupesh
Published: October 2021

Tuberous sclerosis complex (TSC) is a genetic condition caused by a mutation in either the TSC1 or TSC2 gene. Disruption of either of these genes leads to impaired production of hamartin or tuberin proteins, leading to the manifestation of skin lesions, tumors, and seizures. TSC can manifest in multiple organ systems with the cutaneous and renal systems being the most commonly affected. These manifestations can secondarily lead to the development of hypertension, chronic kidney disease, and neurocognitive declines. The renal pathologies most commonly seen in TSC are angiomyolipoma, renal cysts, and less commonly, oncocytomas. In this review, we highlight the current understanding on the renal manifestations of TSC along with current diagnosis and treatment guidelines.

Published: October 2021

Aim: “To evaluate oncological and surgical outcomes of different levels of tumor thrombus and tumor characteristics secondary to renal cell carcinoma (RCC)”.
Materials and Methods: Retrospective review from 2013 to 2020 of 34 patients who underwent radical nephrectomy with thrombectomy for RCC with tumor thrombus extending into the inferior vena cava (IVC) and right atrium (RA) at our center. Level I and most level II tumors were removed using straight forward occluding maneuvers with control of the contralateral renal vein. None of the patients had level III tumor extensions in our study group. For level IV thrombus, a beating heart surgery using a simplified cardiopulmonary bypass (CPB) technique was used for retrieval of thrombus from the right atrium.
Results: “Of the 34 patients with thrombus”, 19 patients had level I, 12 patients had level II, none had level III, and three patients had level IV thrombus. Two patients required simplified CPB. Another patient with level IV thrombus CPB, was not attempted in view of refractory hypotension intraoperatively. Pathological evaluation showed clear-cell carcinoma in 67.64%, papillary carcinoma in 17.64%, chromophobe in 5.8%, and squamous cell carcinoma in 8.8% of cases. Left side thrombectomy was difficult surgically, whereas right side thrombectomy did not have any survival advantage. Mean blood loss during the procedure was 325 mL, ranging from 200 to 1000 mL, and mean operative time was 185 min, ranging from 215 to 345 min. The immediate postoperative mortality was 2.9%. Level I thrombus had better survival compared to level II thrombus.
Conclusion: Radical nephrectomy with tumor thrombectomy remains the mainstay of treatment in RCC with inferior venacaval extension. The surgical approach and outcome depends on primary tumor size, location, level of thrombus, local invasion of IVC, any hepato-renal dysfunction or any associated comorbidities. The higher the level of thrombus, the greater is the need for prior optimization and the adoption of a multidisciplinary approach for a successful surgical outcome.
Treatment of patients with complicated fractures of the distal humerus using the fixators of limited-contact multiplanar osteosynthesis
Authors: Bilinskyi Petro
Published: October 2021

Treatment of distal humerus fractures is a complex problem in traumatology. The result of treatment depends on the choice of fixator according to the fracture area. Objective. To improve the techno­logy of treatment in patients with complicated distal humerus fractures with fixators of small contact and multiplanar osteosynthesis and to evaluate its efficacy. Methods. 39 patients were treated for the period 2000–2020 with distal humerus nonunion (types 12-B1, 12-C1, 12-C2) and 23 patients with complicated above- and transcondylar humerus fractures (types 13-A2, 13-C1, 13-C2). Fixation of bone fragments of the distal humerus was made with device for fixation (Patent 17502 UA). It is a shaped plate with a groove on which half rings with threaded holes are stabilized. For the osteosynthesis of above- and transcondylar humerus fractures we used V-shaped plate with the possibility to regulate branch spreading width as for the condylar size (Patent 33358 UA). Autografting was performed as for necessity. Results. Plate osteosynthesis was performed mainly through anterior approach with minimal tissues traumatization. Release of radial nerve we made as for necessity. This device provides the stable fixation even in a case of short distal fragment. Device for bone fragments fixation was placed on the posterior condylar surface and lower part of the humerus through olecranon osteotomy. Osteosynthesis with suggested device is one of the options with bone autografting and can be method of choice at repeated surgery. Follow-up period was 1–2 years and later. In 60 patients we obtained good results with completed bone union. Conclusions. Suggested device can be used in cases of distal humerus nonunion. It allows to decrease the damage of surgery, to avoid many complications. Key words. Complicated fractures of the distal humerus, devices for limited-contact multiplanar osteosynthesis.

Published: October 2021

Gunshot wounds of the elbow joint are the third most common after knee and shoulder injuries. Features of the anatomical and functional structure of the elbow joint, the close location of the vascular and nervous formations, favorable conditions for the development of infection determine the severity of gunshot wounds and cause the complexity of its treatment. Objective. To evaluate the frequency and nature of the elbow joint gunshot wounds in the structure of the general combat injuries, as well as to determine the volume of medical care and direction of treatment of such injuries in the conditions of the regional hospital as a stage of care. Methods. A retrospective study included 1 809 patients (96.0 % of men, mean age (33.7 ± 0.2) years). Firearms limb injuries were detected in 1 013 (56.0 %) of all victims, of which the elbow joint — 25 (2.47 %). Mines and explosives injuries were in 22 (88 %) of the patients, bullet — in 3 (12 %). Results. Tactics of treatment of elbow joint gunshot wounds depended on the severity of the condition of the victims and the nature of concomitant traumatic injuries. In the structure of combat injury of the elbow joint the majority was combined (52 %) and multiple (40 %) injuries and was accompanied by gunshot fractures in 60 %. In patients who were in severe state, applied the tactics of Damage control in two stages. At the first stage the fractures were fixed with plaster splints or external fixation devices (EF), the wounds were not subjected to full surgical debridment (SD), but only washed with antiseptics and the visible foreign bodies were removed. In patients with soft tissue injuries wounds the primary SD was performed according to general principles, injured nerves were not restored. In the second stage, after patient is stabilized, the repeated SD of the wound was performed. After their uncomplicated healing the EF was removed and the method of fixation was changed to internal osteosyntesis. Conclusions. It is recommended to perform stabilization of intra-articular gunshot fractures of the elbow joint with EF and after uncomplicated wound healing go to the internal osteosynthesis. Key words. Elbow joint, gunshot wounds, treatment.

Published: October 2021

Congenital equinovarus clubfoot (EVC) is the second most common congenital anomaly of the musculoskeletal system in children and one of the most common causes of childhood disability in Ukraine. The frequency of EVC reaches 1–3 cases per 1 000 newborns (35–40 % of all foot deformities). Objective. To determine the features of the children ability with EVC recurrences, before and after surgical treatment by «traditional» methods and Ponseti method. Methods. Biomechanical examinations of 65 children with EVC recurrences were performed. They were divided into two groups: group I (33 patients) — treated by «traditional» methods, which provided initial surgery, in order to completely correct all components of the deformity; group II (32 patients) — treatment by Ponseti method. Weight-bearing function was studied for all patients, before treatment, after 6 and 12 months after surgery, with statography. Results. It was determined that the standing parameters in the groups were not statistically different. After 6 months after the treatment, according to the statograms, the weight-bearing displacement remained, under the conditions of two weight-bearing standing towards the contralateral limb, in both groups of patients. In group I, after treatment, this parameter did not change (p = 0.924), and in group II it decreased by (2.7 ± 4.7) % (p = 0.013). Weight-bearing on the operated limb in both groups, in 12 months from surgery increased by 45 %. Conclusions. In patients, after treatment of EVC recurrences by Ponseti method, the weight-bearing function indicators, in the case of two weight-bearing standing, changed statistically significant. During the recovery process, when patients began to load the operated foot, a slight deterioration of standing parameters was observed in patients of group I in 6 months from surgery. In patients of group II, a complete restoration of statographic parameters occurred earlier, in 6 months, a normalization of weight-bearing and stability was observed. Thus, it can be argued that the use of Ponseti method in the complex treatment of EVC allows to restore the ability of weight bearing much earlier than with the «traditional» method. Key words. Congenital talipes equinovarus, children, Ponseti method, statography.
Molecular hydrogen as a possible therapeutic factor in complex rehabilitation therapy in patients with muscular skeletal disorders (literature review)
Authors: Makolinets Vasyl , Grashenkova Tamara , Moseichuk Volodymyr , Makolinets Kyrylo , Moseichuk Vladyslav
Published: October 2021

The paper presents an analysis of foreign scientific and medical data on the therapeutic factor — molecular hydrogen. The effectiveness of its application in the complex therapy of many diseases is revealed. The effect is achieved due to the small size of the mo­lecule, which passes through biological membranes and inhibits dangerous free radicals in the mitochondria, as well as in the nuc­leus, which reduces the possibility of DNA damaging. Molecular hydrogen neutralizes oxidants in the brain due to its ability to cross the blood-brain barrier. It normalizes the functions and metabolic processes in the body and, as an antioxidant, is selective: it does not affect the useful free radicals involved in important metabo­lic processes and selectively eliminates only the most dangerous oxidants — hydroxyl radicals. Interacting with them, hydrogen converts them into water molecules without the formation of by-products and chain reactions. Unlike other known antioxidants, molecular hydrogen does not disrupt normal metabolism, does not cause negative changes in cells, activates the body’s own anti­oxidant systems. The possibility and expediency of the use of molecular hydrogen in the case of pathology of the musculoskeletal system has been confirmed. The peculiarities of its effect on bone and cartilage tissue in the experiment are shown. It has been determined that the use of molecular hydrogen is a new pharmacological strategy aimed at the selective removal of ONOO—, and can be an effective method in the treatment of joint diseases. Because cartilage receives nutrients through a diffusion-loading mechanism, and molecular hydrogen penetrates rapidly into tissues, it can be useful for the prevention of diseases of joints of degenerative origin. It reduces oxidative stress and slows down the reduction of matrix proteins and inhibition of proteinase degradation. Its effectiveness has been proven after injuries to the spinal cord, muscles and tendons, comorbid diseases such as hypertension, coronary heart disease, diabetes and metabolic syndrome. Key words. Molecular hydrogen, hydrogen water, hydrogen inhalations, joint diseases, consequences of musculoskeletal injuries, comorbid pathology.

Resumo Este trabalho objetivou apresentar aspectos relacionados à utilização do ultrassom no processamento de frutas e hortaliças, como o funcionamento do método, os efeitos no alimento, as aplicações, os aspectos sensoriais e a percepção dos consumidores. As mudanças dos hábitos alimentares e a busca do bem-estar refletem no aumento da procura por alimentos naturais, como as frutas e as hortaliças. Estes alimentos podem sofrer alterações microbiológicas ao longo da cadeia produtiva, sendo necessária a aplicação de boas práticas agrícolas e de manipulação, e processos tecnológicos de conservação para a garantia da qualidade do produto. O ultrassom é uma tecnologia emergente aplicada no processamento de frutas e hortaliças que está relacionada a melhorias na qualidade e preservação. O princípio básico do ultrassom é a cavitação acústica, que envolve o crescimento e colapso de bolhas durante períodos de rarefação e compressão, causando alterações químicas, físicas e mecânicas no alimento. Essas alterações estão relacionadas à inativação de micro-organismos e de enzimas, à remoção de resíduos e às melhorias na qualidade físico-química, e à acessibilidade de compostos bioativos. Além disso, a aplicação deste método pode ter boa aceitabilidade pelos consumidores, que procuram alimentos mais naturais e submetidos a processos que não causem impacto ambiental.

Published: October 2021

Resumo Apesar do incremento de estudos e discussões sobre os povos indígenas no Brasil, a relação da Psicologia, enquanto ciência e profissão, com a temática ainda é pouco abordada nos cursos de graduação e pós-graduação e nas produções acadêmicas. Com o propósito de realizar um balanço sobre a aproximação da produção do conhecimento em Psicologia com a temática indígena, este ensaio buscará apresentar as principais categorias teóricas e analíticas que possam contribuir com o diálogo entre esses dois campos. O método tomou como base a revisão integrativa, em que primeiramente destacamos as principais contribuições teóricas e analíticas acerca da produção acadêmica brasileira sobre os povos indígenas para, em seguida, situarmos a produção científica da Psicologia sobre o tema no Brasil. Ao final, sinalizamos para a importância de se construir um recorte crítico capaz de fortalecer a Psicologia nos estudos sobre os povos indígenas. Também destacamos os estudos pós-coloniais e decoloniais críticos ao eurocentrismo enquanto organizador e regulador da visão de mundo, da história e da concepção de ser humano.

Published: October 2021

Abstract Introduction: Chronic kidney disease (CKD) is a serious public health problem worldwide, leading to a series of physical and psychological comorbidities, in addition to costly treatments, lifestyle and dietary restrictions. There is evidence that mindfulness-based interventions (MBIs) offer complementary treatment for people with chronic illnesses, including CKD, with the aim of improving overall health, reducing side effects and treatment costs. This review aims to investigate the MBIs impact on people with CKD undergoing hemodialysis, and to identify the methodological quality of the current literature in order to support future studies. Methods: We ran searches in five databases (MEDLINE via PubMed, PsycINFO, Embase, Web of Science and Scopus) in July 2020. The papers were selected and evaluated by two reviewers independently, using predefined criteria, including the Cochrane Group's risk of bias tool and its recommendations (CRD42020192936). Results: Of the 175 studies found, 6 randomized controlled trials met the inclusion criteria, and ranged from 2014 to 2019. There were significant improvements in symptoms of anxiety, depression, self-efficacy, sleep quality, and quality of life (n=3) in the groups submitted to the intervention, in addition to physical measures such as blood pressure, heart rate and respiratory rate (n=1). Conclusions: MBIs can offer a promising and safe complementary therapy for people with CKD undergoing hemodialysis, acting on quality of life and physical aspects of the disease.
Nietzsche e a Boa Espiritualidade Europeia
Authors: Gori Pietro
Published: October 2021

Resumo: O artigo tem como objetivo refletir sobre o ideal antropológico delineado por Nietzsche em seu último período. O modo como Nietzsche trata de conceitos tais como os de “alemão”, “bom europeu”, e “espírito livre” nas seções de Crepúsculo dos ídolos dedicadas a Goethe, será abordado de maneira especial. Finalmente, argumentar-se-á que o Renascimento desempenha também um papel importante no projeto antropológico de Nietzsche, uma vez que contribui para definir a força espiritual que caracteriza o tipo de homem saudável ao qual Nietzsche destina a sua sabedoria filosófica e gaia ciência.
Edward W. Said leitor de Nietzsche,
Authors: Stellino Paolo
Published: October 2021

Resumo: Não obstante a filosofia de Nietzsche tenha exercido uma grande influência no pensamento de Said, essa influência ainda tem recebido pouca atenção crítica. O objetivo deste artigo é remediar essa lacuna incidindo particularmente nas diversas analogias que ligam o perspectivismo de Nietzsche à concepção de Said, presente em seu notório livro Orientalismo, segundo a qual não é possível haver representação verdadeira, uma vez que toda representação implica uma interpretação, que é ela mesma uma reconstrução do objeto de interpretação. A última parte do artigo busca mostrar que, embora ambos compreendam o conhecimento humano como perspectivo, nem Nietzsche, nem Said defendem um relativismo epistemológico radical.
Nas origens da vontade de potência: Anaxágoras
Authors: Busellato Stefano
Published: October 2021

Resumo: O presente artigo estuda a interpretação nietzschiana de um pré-socrático pouco considerado pela literatura secundária: Anáxagoras de Clazômenas. São evidenciados alguns elementos da completa originalidade interpretativa de Nietzsche com relação à tradicional exegese do filósofo grego, como, por exemplo, a leitura do Nous em termos materialistas, a explicação do nascimento das qualidades de disposições quantitativas ou interpretar as homeomerias anaxagorianas como pontos de força. Dessas e de outras características da leitura nietzschiana de Anaxágoras emergem aspectos específicos que se encontrarão adiante na teoria da Vontade de potência, teoria, portanto, que possui, na interpretação de Anaxágoras, a primeira elaboração teórica.

Authors: AYKAN Sanem Aslıhan , ÇELİK TAM Dudu , ÖZSOY ÜNÜBOL Tuğba , KILAÇ Hilmi , UÇAN Halil , DALYAN Meltem
Published: October 2021

Background and Purpose: Glenohumeral subluxation (GHS) is a common complication of hemiplegia after stroke. The inferior dislocation is the most frequently encountered GHS in stroke patients, and it is important to choose the proper treatment to promote better stability after repositioning the humerus. To evaluate the short term effect of the California tri-pull taping method with elastic kinesiotape (CTPK) on pain, recovery of movement and daily life activities in Turkish hemiplegic patients.
Methods: Fourteen hemiplegic participants with GHS involved in this study All patients had at least three weeks of conventional inpatient neurorehabilitation. During the rehabilitation program, all patients with GHS had kinesiotaping four times with five-day interval for three weeks. Outcome measures were a verbal descriptive pain scale (VPDS), the Katz index of independence in activities of daily living, and a radiologic and physical examination.
Results: No significant difference was found between the participants with regard to sex, age, duration of stroke, and VPDS scores (p>0.05). Motor recovery stages were improved after CTPK, pain scores decreased, and Katz index increased with the treatment. Passive ROMs of the shoulder were significantly increased. Subluxation was found by palpation to be improved but did not show any radiographic changes.
Conclusion: CTPK can reduce pain and improve quality of life, passive ROM and subluxation. Our findings suggest that radiological grading of subluxation is not sensitive enough and should not be used to evaluate improvement of inferior subluxation in stroke patients.

Conclusion: In the first stage of treatment for a reaction time of 60 minutes a turbidity removal of 96.2%, 65.4% sulfide and 52.3% of TOC was obtained, with these it was determined that with 4 electrodes the greatest removal was obtained. In the second stage with follow-up treatment in function of time, a removal of 99.2% for turbidity, 68.35% for sulfur and 53.5% for TOC was obtained.

Originality: An electrochemical system is used to treat wastewater from the tannery industry, based on previous research, in order to adapt the technology to the sector mentioned initially.

Limitations: The study is limited to the use of iron electrodes, current densities and doses of H2O2 used, in this type of systems aluminum electrodes, stainless steel, graphite and doped materials can be used to maximize the reaction in the electrodes, as well as the use of ozone as an oxidizing agent.
The effectiveness of dry needling on hamstring flexibility: A systematic review
Authors:   Department of Exercise Science and Sport Sciences Augustana University., James Day, , Kyla Kasuske ,   Department of Exercise Science and Sport Sciences Augustana University.
Published: October 2021

Background: Hamstring injuries are a common problem for athletes, and hamstring tightness has been found to be a contributing factor to these injuries. Dry needling is a growing trend that poses the possibility of increasing flexibility through several mechanisms; however, there is currently no review on all of the studies done concerning the effectiveness of dry needling for improving hamstring flexibility. Purpose: The purpose of this systematic review was to evaluate the effectiveness of dry needling on hamstring flexibility in people with hamstring tightness. Methods: Search terms included dry needling or intramuscular stimulation, flexibility or range of motion or ROM, and hamstring. The databases searched were PubMed, MEDLINE, SPORTDiscus, and Cumulative Index to Nursing and Allied Health Literature (CINAHL.) Results: Ten articles were found from the initial search, and three remained after the removal of duplicates and screening the articles for abstracts and full text. Patients consisted of relatively young individuals with hamstring tightness. All studies used a stretching group for the comparison while interventions consisted of dry needling alone or dry needling with a stretching program. No studies showed a significant difference between dry needling and the control; however, all studies found that flexibility increased from baseline measurements following a dry needling treatment. Discussion: The results indicate that while dry needling may not be a better option than stretching, it could be used as a means for improving hamstring flexibility. Possible factors for the effectiveness of dry needling include increased blood flow and oxygen saturation to the muscle as well as the release of myofascial trigger points. Conclusion: Dry needling was not found to be significantly better than stretching, but poses a possibility as another method for improving hamstring flexibility. KEY WORDS: Hamstrings, Athletes, Flexibility, Tightness, Dry Needling, Stretching.

Por meio dos planos de aula e dos depoimentos dos adultos participantes, notamos que esta aula aberta é um espaço de socialização que permite aos adultos experienciar e reconhecer os desafios enfrentados pelas crianças, além de ser um momento para resgatar a infância. Já para as crianças, ela reforça o engajamento nas atividades que podem ajudar no ensino. Com isso, entendemos que a atividade se mostra fulcral para o aprendizado das crianças e para que os responsáveis se aproximem do processo por elas vivido no que tange à prática do circo.
Polarons on Dimerized Lattice of Polyacetilene. Continuum Approximation
Authors: Astakhova T.Yu. , Vinogradov G.A.
Published: October 2021

A one-electron model is proposed to describe a polaron on a dimerized polyacetylene lattice. Within the framework of the formulated model, the dynamics of a freely moving polaron is considered. The results obtained are compared with the many-electron model that takes into account all π-electrons of the valence band. Polaron can move at subsonic and supersonic speeds. The subsonic polaron is stable. A supersonic polaron loses stability at times ∼ 6 000 fs. A supersonic polaron has a forbidden speed range. An analytical solution to the continual approximation helps to understand the reason for the existence of forbidden speeds. The dynamics of a free polaron is similar to the dynamics of a polaron in an electric field. The proposed one-electron approximation significantly expands the possibilities of numerical simulation in comparison with the traditional many-electron model.
2D-to-3D Projection for Monocular and Multi-View 3D Object Detection in Outdoor Scenes
Authors:   Faculty of Mechanics and Mathematics, Moscow State University, Moscow, 119234, Russian Federation, Rukhovich D. D.
Published: October 2021

In this article, we introduce the task of multi-view RGB-based 3D object detection as an end-to-end optimization problem. In a multi-view formulation of the 3D object detection problem, several images of a static scene are used to detect objects in the scene. To address the 3D object detection problem in a multi-view formulation, we propose a novel 3D object detection method named ImVoxelNet. ImVoxelNet is based on a fully convolutional neural network. Unlike existing 3D object detection methods, ImVoxelNet works directly with 3D representations and does not mediate 3D object detection through 2D object detection. The proposed method accepts multi-view inputs. The number of monocular images in each multi-view input can vary during training and inference; actually, this number might be unique for each multi-view input. Moreover, we propose to treat a single RGB image as a special case of a multi-view input. Accordingly, the proposed method can also accept monocular inputs with no modifications. Through extensive evaluation, we demonstrate that the proposed method successfully handles a variety of outdoor scenes. Specifically, it achieves state-of-the-art results in car detection on KITTI (monocular) and nuScenes (multi-view) benchmarks among all methods that accept RGB images. The proposed method operates in real-time, which makes it possible to integrate it into the navigation systems of autonomous devices. The results of this study can be used to address tasks of navigation, path planning, and semantic scene mapping.

The paper proposes methods and algorithms for collision detection of bounding cylinders that surround the geometry of virtual objects. The proposed solutions are based on the separating axis theorem and analysis of possible contact interaction cases between two cylinders. The idea is to approximate the cylinders by prisms with their Gauss map to the unit sphere, which reduces the number of separating axes. Also, to compute contact points, an approach was developed based on fast geometric tests, in which polygon and segment are clipping by a prism, as a common perpendicular between line segments and a point on the circle are found. Based on methods and algorithms proposed in this work, software modules were implemented. Approbation of these modules in the virtual environment system VirSim, which was developed in Scientific Research Institute for System Analysis of the Russian Academy of Sciences, showed the adequacy and effectiveness of created methods and algorithms for real-time simulation of virtual cylindrical objects. The results obtained in this work can be used to solve many practical problems in virtual environment systems, training complexes, educational applications, animation, computer games, etc.

BACKGROUND: Currently, an infectious corneal ulcer, a defect in the corneal epithelium, remains one of the main causes of monocular blindness, which necessitates the development of new effective methods of treatment.
AIMS: The aim of the study is to develop and evaluate the effectiveness of a methodology for the complex application of preformed physical factors of local and segmental action in patients with corneal ulcers.
MATERIALS AND METHODS: The study involved 85 patients with corneal ulcer defect aged 18 to 60 years, who were divided into three groups. Patients of the control group (29 people) received standard drug therapy, the comparison group (29 people) underwent a course of magnetophoresis with solcoseryl on closed eyelids against the background of standard drug therapy, patients of the main group (27 people) received standard drug therapy. magnetophoresis and low-frequency electrostatic fields on the collar area. All patients were assessed for visual acuity, the size of the ulcer and the area of stromal infiltration. The subjective severity of pain syndrome (VAS scale), psychoemotional state (SAN test) were assessed.
RESULTS: Immediately after treatment, visual acuity in the main group was significantly higher than in the comparison group and the control group, and averaged 0.140.14. The size of the ulcerative defect in the main group was significantly smaller than in the control group and the comparison group (p 0.05). The assessment of the psychoemotional state of patients after treatment revealed significant differences in the main group in relation to the control group on the Well-Being scale (p 0.05).
CONCLUSION: The use of preformed physical factors in the form of a course application of a low-frequency electrostatic field and magnetophoresis with the drug Solcoseryl made it possible to shorten the time of epithelialization of the ulcer and suppression of the inflammatory reaction in the cornea, which made it possible to significantly improve the clinical and functional parameters of the eye, as well as reduce the severity of pain syndrome against the background of an improvement in the psycho-emotional state patients.

The article provides a brief overview of the issues of nutritional therapy in the rehabilitation of cancer patients. Excess sugar in food and drink, fatty and high-calorie foods, processed meat, trans fatty acids, preservatives and dyes are risk factors for the formation of malignant tumors. Patients should be informed about adherence to a healthy lifestyle and exclusion from the diet of foods containing carcinogens to reduce the recurrence of the disease. Chemotherapy courses and radiation sessions are accompanied by a number of side effects that lead to a decrease in the body's defense systems. For the recovery of cancer patients, protein, vitamins and minerals must be present in the diet. All nutrients are better obtained from the natural foods. To maintain a healthy diet, the World Cancer Research Foundation (WCRF) and the American Institute for Cancer Research (AICR) recommends you toinclude vegetables, fruits, whole grains and legumes in your daily diet. The article focuses on mare's milk, its multicomponent composition, which has immunomodulatory, antiviral, antibacterial properties. To increase the effectiveness of rehabilitation measures in patients after antitumor treatment, it is advisable to include mare's milk in medical nutrition, which has therapeutic and health-improving properties, and it is also possible to use it in patients undergoing antitumor cytostatic therapy. Further comprehensive study of the therapeutic and rehabilitation potential of mare's milk would make it possible to use this product more widely as an important component of nutritional support for cancer patients during specific therapy courses, which will have a positive effect on their survival rates and quality of life. In the treatment of malignant tumors, the main emphasis is on the development of strategies, new treatment options, and medical nutrition and a healthy lifestyle are an integral part of their complex rehabilitation.

BACKGROUND: Hepatitis B is an urgent medical and social problem in Russia.
AIM: To determine the epidemiological features of the hepatitis B in the Russian Arctic.
MATERIALS AND METHODS: We carried out a retrospective analysis of the incidence of hepatitis B (acute and chronic forms) in 9 Russian Arctic regions, 3 subarctic regions (Khanty-Mansiysk Autonomous Okrug, Magadan Region, Kamchatka Territory) and Russian Federation in 19992019. We also studied the prevalence of chronic hepatitis B and vaccination data against hepatitis B in these territories.
RESULTS: From 1999 to 2019 the incidence of acute hepatitis B in three subarctic regions decreased 166 times (from 66.5 to 0.4 per 100 thousand population), in the Arctic zone of 74.5 times (from 29.8 to 0.4 per 100 thousand population) and 73 times in Russia (from 43.8 to 0.6). The incidence of chronic hepatitis forms in the same period in the Arctic zone decreased by 8.6 times (from 140.1 to 16.3), 5.8 times in the subarctic regions (from 116.6 to 20.0) and 5.7 times in Russia (from 96.3 to 16.8). In 2018, the results of the prevalence of chronic hepatitis B in the Arctic zone (697.3) was higher than in Russia by 98% (352.1) and higher in the subarctic regions by 67% (588.6). Timely coverage of hepatitis vaccination in children aged 12 months in the Russian Federation, the Arctic zone and the subarctic regions is maintained at a high level (more than 90%) from 2004 in 2019. Coverage of children by vaccination to 17 years inclusive and adults up to 35 years on these territories also exceeded 90%.
CONCLUSIONS: Vaccination against hepatitis B in the Russian Federation led to a significant decrease in the incidence of this infection in the Russian Arctic. High prevalence of infection indicates the need to continue the program of mass vaccination and the timely introduction of the first dose of vaccine newborns. To reduce the risk of cirrhosis and liver cancer, it is necessary to increase the availability of diagnosis of the disease and its possible outcomes in the Arctic regions and timely provision of antiviral treatment of all patients.

AIM: This study aimed to identify the main trends of the epidemiology of tuberculosis in children and adolescents in the Ryazan Region (RR) by analyzing the main epidemiological parameters of morbidity in 20102019.
MATERIALS AND METHODS: The morbidity of children and adolescents with tuberculosis in the RR was subjected to retrospective epidemiological analysis. The data of the official and reporting documentation of the Ryazan Regional Clinical Antituberculosis Dispensary and the materials of the state reports of Territorial Administration of Rospotrebnadzor (On the Condition of SanitaryEpidemiological WellBeing of Population) in 20102019 were used. The main epidemiological parameters of morbidity due to tuberculosis were calculated using mathematical methods.
RESULTS: The proportion of children and adolescents in the structure of morbidity due to tuberculosis in the RR in 20102019 decreased by 3.9 times and reached 6.09% in 2019. The morbidity caused by the active form of tuberculosis in children (014 years) and adolescents (1517 years) evidently declined by -20.7% and -11.5%, respectively. In children, respiratory tuberculosis predominated (55%100%), and the leading clinical form was tuberculosis in intrathoracic lymph nodes (77%). In adolescents, only pulmonary tuberculosis was identified, and focal tuberculosis was the predominating clinical form (43%). In the study period, the highest morbidity in children was recorded at the age of 714 years. No cases of mortality among children and adolescents with tuberculosis were recorded in 20102019. In 20182019, the primary infection and the risk of infection among children under 14 years of age increased from 1.3% (2018) to 1.8% (2019) and from 2.6% (2018) to 3.3% (2019), respectively. This result might indicate that morbidity due to tuberculosis increased. The majority of ill children and adolescents were identified among vaccinated ones, suggesting that the protective properties of the vaccine were insufficient (80%).
CONCLUSION: The morbidity of children and adolescents with tuberculosis decreased, and this decrease directly associated with the general improvement in the status of tuberculosis in the country; in particular, tuberculosis foci in the RF decreased by 2.2 times [4]. In the study period, the morbidity of children (014 years) decreased by 3.5 and 2.1 times in the RR and RF, respectively. The morbidity of adolescents (1517 years) decreased by 3.1 and 2.2 times in the RR and RF, respectively. The mortality of children and adolescents in the RP was 0.0 per 100,000 population of the given age groups. In the RF, their mortalities reduced by 6.5 and 1.6 times, respectively [4].
