Modern optical bioimaging technologies make it possible to objectively assess these changes. \u0000AIM: To study metabolism and morphological structure features of the mucous membrane of the relatively normal colon in patients with colorectal cancer. \u0000MATERIAL AND METHODS: The object of study was the colon mucosa in patients with colorectal cancer stages I–IV. The study included 59 patients. There were 33 (56%) men, 26 (44%) women; median age — 67 [61; 74] years. In 10 cases, the tumor was localized in the right colon, in 9 — in the transverse colon, in 23 — in the sigmoid colon, in 17 — in the rectum. 7 samples were obtained from patients with stage I, 25 — with stage II, 21 — with stage III, 6 — with stage IV colorectal cancer. The metabolism of colon tissue from the mucosal side was studied using fluorescence-lifetime macroimaging, and the microstructure was studied using optical coherence tomography and histological examination. The results of calculating the weighted average fluorescence lifetime were presented as median values Me [Q1; Q3], comparison of this indicator between groups was carried out using the nonparametric Kruskal–Wallis test. \u0000RESULTS: According to histological examination, progression signs of structural changes with increasing stage of colorectal cancer were revealed: from the conventional norm in samples with stage I to the appearance of signs of chronic colitis, atrophy and erosion of the mucous membrane in samples with stages II, III and IV. Visual analysis of optical coherence tomograms obtained from colon samples showed a high degree of agreement with histological data: the Spearman correlation coefficient was r=0.96. According to fluorescence-lifetime macroimaging, statistically significant differences (p=0.027) in the weighted average fluorescence lifetime were detected between stages IV and II of colorectal cancer: the values were 1.6 [1.4; 1.8] ns and 1.3 [1.1; 1.4] ns, respectively, which indicated an intensification of the glycolysis process in the tissues of the colon mucosa in stage IV colorectal cancer. Presumably, the identified changes will become the pathophysiological and anatomical basis of postoperative complications. In clinical oncology, it is advisable to use the obtained data to optimize the volume of intestinal resection and postoperative therapy algorithms. \u0000CONCLUSION: Long-term tumor carriage and progression of colorectal cancer (invasion and metastasis) are associated with an increasing incidence of atrophy/erosion of the mucous membrane, the signs of which are determined both by optical coherence tomography and by histological examination.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"112 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140783293","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}

With approximately 10% of infants worldwide being born preterm, there is an increasing need for further research into optimal regimens, lifestyle and clinical interventions that can benefit and modify cardiovascular morphology and function in this growing population. Modern theoretical postulates on the physiology and pathophysiology of the child’s heart include ideas about the key process of cardiac biomechanics — diastole, during which the earliest disturbances, that precede the formation of systolic dysfunction, occur. Assessment of the pumping properties of the left ventricle in systole and diastole is a fundamental methodological technique for an in-depth understanding of the pathophysiological mechanisms of cardiovascular system’s emerging diseases, their early diagnosis and assessment of the complex therapy’s effectiveness. However, despite the widespread use of standard echocardiography to assess systolic and diastolic function, its traditional parameters have limitations in terms of diagnostic accuracy and effectiveness in practice. Expanding knowledge about new pathogenetic mechanisms of the cardiac dysfunction formation in conditions of prematurity at the current stage of cardiology development using the “trace spot” technology (two-dimensional speckle tracking echocardiography) will be very useful for scientists studying the mechanics formation of the child’s heart after premature birth, and for doctors of various specialties in early diagnosis of heart diseases.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"183 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140794159","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}

This study is a systematic review of biochemical and neuronal markers of different levels of coping intelligence, which determine different lines of human development in stressful situations. 45 publications selected from the Nature and RSCI electronic databases were analyzed, the results were summarized in three sections: (1) genetic and epigenetic correlates of individual differences in coping intelligence; (2) neurochemical systems of coping intelligence (glucocorticoids, interleukins, brain-derived neurotrophic factor, monoamines); (3) manifestations of stable and regressive lines of development of the subject in stressful situations. Molecular genetic determinants of coping intelligence were systematized according to the following systems: serotonergic, dopaminergic, noradrenergic, etc. The interaction of neurochemical systems (catecholamines, glucocorticoids, interleukins, brain-derived neurotrophic factor, monoamines) reflects the peculiarities of the stress reaction in humans and determines the development line of the subject in stressful situations. Genetic predisposition, unfavorable epigenetic factors and chronic stress increase the risk of developing stress-related diseases (regressive line of development). A stable stress-coping system is associated with a balance of mineralocorticoid and glucocorticoid receptors, pro-inflammatory and anti-inflammatory cytokines, an optimal ratio of cortisol and dehydroepiandrosterone sulfate, a sufficient level of brain-derived neurotrophic factor, and a healthy microbiota (stable line). A review of the literature indicated the need to analyze neurochemical systems (monoamines, opioid receptors, acetylcholine, microbiota) that determine a high level of coping intelligence (a progressive line of human development in stressful situations). The study of neurochemical markers of coping intelligence should be accompanied by personality analysis (mental representations of stress, coping strategies) to provide personalized medical care and preserve a person’s health potential.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"40 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140768771","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}

All subjects underwent radical surgical treatment. In the postoperative period, postoperative complications were recorded in 40 patients. All subjects underwent anthropometric and bioimpedance examination. Height and body weight, transverse diameter of the chest, width of the shoulders and pelvis, waist and hip circumference, and body morphotype were determined. Bioimpedansometric examination was carried out before surgery and in the postoperative period using a domestic hardware and software complex with determination of the body component composition and the phase angle value. The phase angle of impedance reflected the metabolic rate in the body. The results were statistically processed using descriptive statistics methods. The Shapiro–Francia, Kolmogorov–Smirnov tests, Student's t-test, Mann–Whitney test, and the logistic regression method were used. Differences were considered statistically significant at p 0.05. \u0000RESULTS: Women of the gynecomorphic body type were characterized by a significant decrease in the relative values of active cellular and skeletal muscle mass (p=0.001; p=0.001), and the phase angle value until 12–14 days after surgery (p=0.001). Men of the andromorphic body type were characterized by a significant decrease in the relative values of active cell mass (p=0.001) and the phase angle until 12–14 days after surgery (p=0.001). In women of a gynecomorphic morphotype, the likelihood of postoperative complications was 4 times higher than in women of an andromorphic morphotype (p=0.001). Representatives of the mesomorphic body morphotype of both sexes were characterized by stable bioimpedance measurements during the entire postoperative period. \u0000CONCLUSION: Low values of the phase angle in men and women, as well as the classic gynecomorphic body type in women can be used in oncoabdominal surgery as predictors of a high risk postoperative complications developing in patients with gastric and cardioesophageal junction cancers.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"46 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140796114","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}

In this regard, there is a special need to resolve issues of diagnosis and correction of not only the main symptoms of this disease, but also numerous associated somatic disorders. One of the common clinical manifestations in children with autism spectrum disorder is pathological eating behavior, which includes disturbances in eating habits and preferences, frequency of meals, etc. Despite the fact that eating disorders can also occur among normotypical coevals, in children with autism spectrum disorder, these manifestations are clinically more diverse, vary in severity and often appear earlier than the main symptoms of the disease. It must be emphasized that the correction of certain nutritional disorders in this group of children is often difficult due to the characteristics of the course of the underlying disease. This may be further exacerbated by increased parental anxiety. A timely solution to the problem of eating behavior in children with autistic disorder is of great importance for strengthening their health and reducing the severity of the underlying disease, since the connection between neuropsychic and somatic health is inseparable. In the review, we tried to identify the main factors involved in the formation of eating disorders in children with autism spectrum disorder, and presented existing practical tools for analyzing this medical problem and managing their nutrition for preventive and therapeutic purposes.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"25 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140227027","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}

In this regard, the development of test objects (phantoms) that simulate the X-ray properties of tissues, including for preliminary assessment of the ionizing radiation distribution, becomes relevant. These test objects play an important role in quality control and the development of new medical imaging methods in conditions where test scans of patients are not possible. Although a range of ready-made solutions is available on the market, there is a lack of prototypes with a certain set of properties to test scientific and practical hypotheses in solving specific clinical and technical problems. Finding materials for a fast and inexpensive production process and studying their properties could provide insight into the effectiveness of their use in making phantoms. The purpose of the work is to search and analyze materials for creating phantoms used in computed tomography. The article discusses materials for the production of non-anthropomorphic and anthropomorphic phantoms, including those printed on a 3D printer. The development of three-dimensional printing has facilitated the transition from simple test objects to high-precision anthropomorphic phantoms made from tissue-mimicking materials that have equivalent signals on computer tomograms. Plastics, silicones, polyvinyl chloride, resins, liquids are used for visualizations identical to soft tissues; plastics, gypsum, photopolymers, potassium hydrogen orthophosphate, calcium hydroxyapatite, plexiglass — for hard tissues. Commercial phantoms are made from materials with reproducible, stable properties, but these same materials must be retested to create test objects specific to a particular clinical task.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"30 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140225616","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}

At the same time, the defect is associated with a number of diseases and conditions: the development of atrial fibrillation, worsening the degree of hypoxemia in patients with pulmonary diseases, etc. There are studies devoted to the influence of a patent foramen ovale on the occurrence and course of cryptogenic stroke, migraine, syncope, dizziness, transient global amnesia, visual impairment and ocular movement disorders. However, the actual contribution of patent foramen ovale to the development of neurological disorders remains a matter of debate. The purpose of this work was to assess the significance of a patent foramen ovale in the development of neurological disorders in adults and children by analyzing literature data for the period from 2012 to 2022. In the process of studying the literature, a high prevalence of the defect was identified among patients with stroke and migraine (especially migraine with aura). At the same time, data from randomized clinical trials in patients with stroke and migraine showed selectively high effectiveness of closure of the patent foramen ovale in certain groups of patients. The association of patent foramen ovale with transient global amnesia, syncope, and dizziness has been confirmed in a limited number of studies. Cases of visual impairment and ocular movement disorders associated with the presence of a patent foramen ovale have been described. Thus, it was concluded that a patent foramen ovale is a risk factor for the development of neurological disorders only in certain groups of patients with stroke and migraine. The connection between the defect and the development of transient global amnesia, syncope, dizziness, visual impairment, as well as the development of neurological pathology in children requires further research.","PeriodicalId":17750,"journal":{"name":"Kazan medical journal","volume":"4 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140230651","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}
