The complexity of diagnostics of haemocoagulation complications in this comorbid pathology remains an urgent problem at present. The aim of our study was to investigate the mechanisms of thrombotic readiness state formation using the thrombodynamics test on the example of patients with cardiovascular diseases (CHD, arterial hypertension) and aggravated oncoanamnesis depending on the activity of oncoprocess. The study was conducted in 100 patients aged 37 – 86 years: 60 patients with active oncoprocess (group 1) and 40 patients with oncoprocess in remission (group 2). Clinical, anamnestic and laboratory data were studied using a statistical analysis. The main attention was paid to the thrombodynamics test indicators (both velocity and structural). It was found that the most informative indicators of the haemostasis system state estimation in patients with cardiovascular pathology and aggravated oncoanamnesis depending on the oncoprocess activity are thrombodynamic indices both velocity and structural. Almost half of cardiological patients with an aggravated oncoanamnesis had a state of thrombotic readiness irrespective of the activity of the oncological process. These indices were higher in active oncopathology than in oncopathology in remission. At the same time no differences in the data of standard coagulogram in both groups could be revealed. Application of thrombodynamics test in cardiological patients with oncoanamnesis allows to reveal the states of thrombotic readiness and to establish the degree of influence of oncoprocess activity on the formation of this state, which demonstrates fundamentally new aspects of diagnostics of procoagulant states in patients of this profile.","PeriodicalId":510261,"journal":{"name":"Вестник Северо-Восточного федерального университета имени М К Аммосова Серия \"Медицинские науки","volume":"285 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prolonged irritating effects are accompanied by inhibition of regenerative processes and subsequent morphofunctional restructuring of the structural components of the lungs. The aim of the study was to research the morphometric parameters of the structural components of the lungs of white laboratory rats at different periods of chronic simulated hypoxia combined with inhalation of natural gas from the Astrakhan field, at a concentration of 3 mg/m3. The study covered 94 white mongrel sexually mature male rats who were in conditions of chronic hypoxia combined with natural gas inhalation for 120 days. The animals were placed in a special seed chamber produced by the Erisman Institute with a volume of 200 liters with a variable composition of the air-gas mixture, and with a decrease in the oxygen concentration in the inhaled air to 17.5 %, natural gas from the Astrakhan field was supplied through a special nozzle. The animals were kept in experimental conditions lasting four hours a day for five days a week. For the manufacture of histological preparations, animals were anesthetized with sodium ethaminal (40 mg/kg weight). Lung tissue samples were fixed in a 10 % solution of buffered formalin. The preparations were stained with hematoxylineosin and Van Gison. The analysis and visualization of the obtained glass preparations was carried out using a ZeissAxioScopeA1 light microscope (Germany) and a LeicaAperioCS2 digital scanner of micropreparations with specialized software. It was determined that the initial significant changes were already formed by 60 days of experimental exposure. In one group of drugs, thickening of the interalveolar septa associated with the processes of edema formation and infiltration by cellular elements were noted, another group of drugs showed emphysemalike changes with stretched and partially torn alveoli. By day 90 of the experiment, a decrease in the airiness of the lung tissue was determined on all preparations, manifested by thickening of the interalveolar septa and a decrease in the diameter of the alveoli. By day 120, the changes identified in the early stages were progressively increasing: there were areas completely devoid of alveoli, other fields of vision showed alveoli with torn walls. On the part of the bronchi, the following pattern was determined: an increased thickness of the walls of the bronchi, mainly due to the mucous and adventitial membranes, followed by deformation of the bronchi of medium and small caliber and the formation of peribronchial infiltrates. The morphometric analysis confirmed that chronic hypoxia combined with natural gas inhalation causes significant changes in the structural components of the lungs.","PeriodicalId":510261,"journal":{"name":"Вестник Северо-Восточного федерального университета имени М К Аммосова Серия \"Медицинские науки","volume":"45 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphofunctional study is the most informative and accessible. However, the somatotype-related functional state of the cardiovascular system of athletes remains insufficiently studied. The purpose of the research: To determine the indicators of the cardiovascular system of athletes in response to physical exertion, depending on the somatotype according to Reese-Eysenck. An anthropometric and functional study of the cardiovascular system of 49 athletes of the highest sports skill engaged in freestyle wrestling at the Sakha Republic’s Center for Traditional Sports was conducted. The Reese-Eysenck index was used to determine the somatotype. Functional examination of the cardiovascular system included blood pressure measurement and pulse counting at rest, then 1 and 2 minutes after exercise. The exercise consisted of a full squat with arms outstretched with a frequency of 20 squats in 30 seconds. In order to determine the tolerance of physical activity, the Roufier index was calculated. The adaptive potential of the cardiovascular system is determined using the index of functional changes. Somatotyping by the Reese-Eysenck index among the examined athletes revealed that a significantly large proportion of the examined individuals had an athletic somatotype. In pyknics, significantly large indicators of body weight and the transverse diameter of the chest were recorded. A functional examination of the cardiovascular system with the use of physical activity revealed a significantly greater increase in systolic blood pressure after 1 and 2 minutes and heart rate 1 minute after physical activity in individuals with the pyknic somatotype compared with others. The analysis of the results of the index of functional changes of athletes depending on the somatotype revealed the stress of the cardiovascular system function only in athletes of the pyknic somatotype. The obtained results indicate that the training process should be selected individually, taking into account the somatotype of an athlete, since among pyknics there are people with stress of the cardiovascular system with good results of physical activity tolerance according to the Roufier index.","PeriodicalId":510261,"journal":{"name":"Вестник Северо-Восточного федерального университета имени М К Аммосова Серия \"Медицинские науки","volume":"40 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New regulatory legal conditions for the development of medical organizations assume that medical organizations participating in the state guarantee program will have the right to provide paid services. Previously, the current procedure assumed that medical organizations providing services under the compulsory medical insurance could provide paid medical care on different conditions than provided for by the state guarantee program. Therefore, the development of private medicine and the problems facing private medical organizations in modern conditions are relevant and require discussion. The purpose of this work is to consider the regulatory legal conditions for the development of private medical organizations in the Russian Federation at the current stage. The conclusion is that today a lot of work is being carried out by the professional community responsible for approving the procedures for the provision of medical care and clinical recommendations, which should be guided by all medical organizations operating in the domestic market of medical services. The infrastructural provision of medicine should meet the needs of the population, ensure the provision of medical care in the specified volumes by type and form and be effective.","PeriodicalId":510261,"journal":{"name":"Вестник Северо-Восточного федерального университета имени М К Аммосова Серия \"Медицинские науки","volume":"25 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

COVID-19 is a “young disease”, which determines the importance of studying the influence of chronic comorbid pathology on the risk of infection with SARS-CoV-2, the severity of the course and the likelihood of developing an unfavorable outcome of the disease. Accumulated data identify several risk groups for severe COVID-19. First of all, this applies to patients with concomitant chronic pathologies: diabetes, cardiovascular diseases, obesity, and others [5, 15]. Coinfections affecting the respiratory tract pose clinical dilemmas as well as diagnostic and therapeutic challenges. This article presents clinical cases of the course of a combination of COVID-19 infection and pulmonary tuberculosis.

A total of 712 adolescents aged 15 –16 years were examined, including 360 girls and 352 boys, residing in the city of Yakutsk, Sakha Republic (Yakutia). The study revealed that among adolescents, low physical activity showed the highest frequency among the risk factors, followed by others in descending order: restrictive eating behavior, high cholesterol and glucose levels, overweight and obesity, and high stress perception. The differences found were based on gender, with boys being more susceptible to obesity. Correlation analyses using Spearman’s (rs) and Pearson’s (rp) coefficients and Pearson’s chi-square test were used to identify relationships between risk factors for cardiovascular diseases. The analysis showed that high blood pressure is associated with adolescents who have high body mass index.

According to WHO, more than 50 million people worldwide suffer from epilepsy. It is estimated that the proportion of the general population with its active form (that is, with recurrent seizures and the need for treatment) currently ranges from 4 to 10 per 1,000 people. Globally, 2.4 million people are diagnosed with this disease every year. In Russia, epilepsy affects more than 1 million people. The analysis of statistical data on the prevalence and incidence of epilepsy in children in the Republic of Sakha (Yakutia) was carried out. In Yakutia, the first epidemiological study of epilepsy in the pediatric population was conducted in 1985 by E.A. Krivogornitsyna. As a result of the survey, data were obtained on 322 children who were registered at the dispensary with neurologists and psychiatrists in 32 districts of the republic and the city of Yakutsk. According to the study of the epidemiology of epilepsy in children in 2004 (Baisheva G.M., 2004), the prevalence of epilepsy was 5.2 per 1,000 children of the Republic of Sakha (Yakutia), and the primary incidence was 114 per 100,000 children. Prevalence of epilepsy in children under 14 years of age in 2020 was 5.4 per 1,000 population, the primary incidence was 50 per 100,000 population. On average, from 2010 to 2020, the primary incidence of epilepsy in children is 80 per 100,000 population. The prevalence of epilepsy in adolescents aged 15 – 17 years averaged 10.4 %. The average value of primary morbidity in this group of children was 140 per 100,000 population.

This article provides a review of the literature on hemostatic disorders during oncological processes in patients with ischemic stroke. Cancer-associated stroke can develop for several reasons, including direct effects of the tumor, as well as indirectly through the development of blood coagulation disorders, concomitant infectious diseases, or complications of antitumor therapy. One of the most common pathogenetic mechanisms is cancer-associated coagulopathy. Trousseau syndrome is a variant of paraneoplastic syndrome, characterized by a state of hypercoagulability with the development of thrombosis that precedes the diagnosis of a malignant neoplasm or develops simultaneously with it. Cerebral ischemia in Trousseau’s syndrome is characterized by a multifocal pattern of lesions according to neuroimaging data. To date, there are no clear diagnostic criteria for cancer-associated stroke, which is often one of the first clinical manifestations of the oncological process. According to various studies, laboratory markers of hypercoagulability can serve as predictors of previously undiagnosed malignancy in patients with cryptogenic ischemic stroke. Currently, more and more attempts are being made to develop diagnostic scales based on clinical and neuroimaging characteristics of stroke to identify hidden oncological processes. Another important aspect of the issue remains the lack of evidence-based recommendations for the treatment of ischemic stroke associated with cancer. Given the prevalence of stroke in cancer patients, potentially poor functional prognosss, higher rates of post-stroke mortality and high relapse rates, further research into this issue is required.","PeriodicalId":510261,"journal":{"name":"Вестник Северо-Восточного федерального университета имени М К Аммосова Серия \"Медицинские науки","volume":"393 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139181089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
