[Pathological changes in the muscular tissue of the colon in diverticular disease]. / Patologicheskie izmeneniya myshechnoi tkani v stenke tolstoi kishki pri divertikulyarnoi bolezni.

The high incidence of colonic diverticular disease (DD) in the general population is a serious public health problem. According to statistics, DD is among the top five most common colorectal diseases. Complicated course of DD is observed in 12-15% of patients, and in 10.7% of cases can lead to death. Algorithms and recommendations for predicting the complicated course of DD for further prevention have not been developed. OBJECTIVE: Comparative analysis of clinical data and structural characteristics of the colonic muscular tissue in patients with different course of DD and without colonic diverticula to identify morphological predictors of a complicated DD. MATERIAL AND METHODS: A comparative analysis of clinical data, pathomorphological and ultrastructural changes of the colonic musculature in the surgical material from 68 patients undergoing left-sided hemicolectomy was carried out. RESULTS: The operative material of 37 patients with complicated course of DD, 19 with uncomplicated course of DD and 12 without diverticula was analyzed. In men, this disease occurs at a younger age than in women (Median age of men 49 (39.5; 61) years, women 66.5 (58; 81) years; U=178, p<0.001). It was shown that the area occupied by connective tissue fibres in the colonic musculature in patients with a complicated DD was 5 times greater (15%) than in observations with an uncomplicated DD (3%) and 50 times greater than in cases without colonic diverticula (0.3%; p<0.001). CONCLUSION: The present study demonstrates age- and sex-specific features of DD, as well as significant differences in the prevalence of fibrosis of the colonic musculature, which can be considered as a potential predictor of a complicated course of DD.

[The application of statistical programs and methods of data mathematical processing in obstetrics and gynecology].

In recent decades, evidence-based medicine acquired special importance in medicine. Therefore, proper presentation of data obtained in scientific research is extremely important. The statistical data processing, being an integral part of this process, often causes difficulties for researchers and its incorrect application results in distortion of results obtained. The purpose of the study is to comparatively analyze programs and methods of statistical data processing applied in dissertations on obstetrics and gynecology in 2011-2021, to examine trends in choosing them depending on specificity of research issue and to identify shortcomings erred by authors in choosing or describing data processing methods. The sampling for analysis included 258 abstracts of candidate's dissertations in the specialty "obstetrics and gynecology", defended in 2011-2021. The analysis covered the programs and methods of mathematical data processing. Over the past decade, significant complication of statistical processing of results of clinical trials in obstetrics and gynecology occurred in part of methods applied. The application of binary logistic regression and discriminant analysis increased most significantly over the past decade. Such sophisticated methods of statistical data processing as factor analysis, decision trees, ordinal logistic regression and neural networks began to be used too. The trend of gradual replacement of parametric methods (Student's t-test, one-way analysis of variance) by such corresponding non-parametric methods as Mann-Whitney test, Kruskal-Wallis test. The Microsoft Excel and Statistica were used most often for data processing. In recent years, the software SPSS Statistics is actively applied. However, problems in describing statistical methods used in dissertations continue to be present. In significant part of dissertations information about statistical program applied, methods of assessing of quantitative data distribution and criteria of significance of obtained results is absent. The proper application of statistical programs, methods of information processing, adequate interpretation of results as well as provision of complete information about methodological support are the key points to carry out modern research resulting in trusted attitude to scientific work and its results.

[DETERMINANTS OF QUALITY OF LIFE AND MORBIDITY IN THE ADULT POPULATION].

In the Russian Federation, the number of working-age population is growing annually: in 2014, the number of able-bodied population was 33.8 million people(23.5%), while in 2018 this figure increased to 37.3 million (25.9%) [6]. In the Republic of Tatarstan, at the beginning of 2019 the number of able-bodied citizens reached 986 thousand people(26.0%). The purpose of this study was to analyze the determinants of the adult living standarts and the impact of these determinants on morbidity rates. A survey of 897 people using the SF-36 international questionnaire "SF-36 Health Status Survey". The majority of the working-age population under study was aged 60-64 (30%) and 65-69 (26%), aged 55-59 and 70-74 were 12% and 18% respectively. The smallest number of those under study was aged 75-79 (8%) and 80 and older (6%). Thus, our research has shown that the living standarts of over working-age population living in a large metropolis tends to significantly decrease depending on the age and gender. There was discovered a high level of prevalence of medical and social risk factors in these individuals, which are involved in the formation of the determinant of living standarts. For the first time, it was revealed that in people over the working age, the intensity of morbidity depends on the level of determinants of living standarts. The data obtained make it possible to develop measures to improve the quality of life of people over the working age and reduce their morbidity.

[The Indices of Morbidity of Main Socially Significant Noninfectious Diseases of Population of the Republic of Tatarstan].

Socially significant diseases cause enormous damage to entire modern society and require higher expenses for prevention, treatment and rehabilitation. The most studied socially significant diseases include cardiovascular diseases, diabetes mellitus, mental disorders, alcoholism, and oncologic diseases. The study purpose is to assess incidence of major socially significant diseases, including malignant nephropathy, mental disorders and alcoholism in the Republic of Tatarstan during 1997-2017. The discussion. According to the analysis results, there was gradual increasing of incidence of malignant necrosis in the Republic of Tatarstan during the analyzed period i.e. from 240.5 cases to 412.9 cases per 100 thousand of population. The incidence of mental disorders in males was significantly higher than in females. The maximal discrepancy of indices, amounting up to 252.6 cases per 100 thousand of population, was different in 1998. The gap gradually decreased and by 2017 made up to to 62.6 cases per 100 thousand of population. The dynamics of the incidence of alcoholism characterized by increasing up to to 2001. Since 2004, gradual decreasing of indicator was in 2011-2017. The incidence of alcoholism ranged from 123.5 to 129.6 cases per 100 thousand of population. Conclusion. The decreasing in the incidence of mental disorders and alcoholism was established during study period, as well as gradual increasing of incidence of cancer in the Republic of Tatarstan.

[Evaluation of population's commitment to healthy nutrition and physical culture (by results of the questionnaire)].

One of the main tasks in implementing the foundations of state policy in the field of a healthy lifestyle of the population is the formation of optimal nutritional status and the preservation of public health. In this regard, issues of a comprehensive self-assessment of health by the population are becoming particularly relevant. The aim of the research was to identify the degree of commitment of the population to a healthy lifestyle, including maintaining a balanced diet and the presence of physical activity, as well as the relationship between the respondents' lifestyle and the presence of non-communicable diseases. Material and methods. A random survey of the adult population of the Rybno-Slobodsky district of the Republic of Tatarstan has been conducted. In total, 2346 respondents aged 21 to 74 (women - 71.7%, people with higher education - 33.2%) took part in the survey. For this study, a questionnaire was developed to identify the attitude of the population to a healthy lifestyle (HLS), which included questions regarding the physical activity of respondents, their commitment to healthy eating and diet, the existence of pernicious habits (drinking, smoking), and the presence of noncommunicable diseases. In the framework of this article, two factors were analyzed: the population's commitment to a balanced diet and physical activity, as well as the relationship of these factors with the presence of non-communicable diseases among respondents. Results and discussion. Data analysis showed that 18.8% of women and 14.1% of men always adhere to healthy eating and proper diet. Women are more committed to healthy eating than men (p<0.001). Regularly (2-3 times a week), 21.4% of women and 18.1% of men are engaged in exercise (a sport or physical activity), that is only 20.6% of respondents (p<0.001). The percentage of people committed to healthy nutrition was almost equal, both in the group of those with and without cardiovascular diseases (CVD) (19.5 and 17.4%, respectively). Among people who regularly engage in physical activity and sports (2-3 times a week), 27.5% of respondents have CVD, while among those who do not engage in exercise, 64.2% of individuals have CVD (p<0.001). Among those who adhered to a balanced diet, gastrointestinal diseases were observed in 14.1% of the respondents, while among the respondents who did not adhere to healthy eating, gastrointestinal diseases were observed in 83.7% (p<0.001). Conclusion Among respondents who adhere to healthy eating and diet and physical activity, non-communicable diseases and stress are less common (according to the respondents' answers). The results of a self-assessment (questionnaire) of public health can be used to develop targeted program of treatment and preventive measures to build community commitment in the Rybno-Slobodsky district of the Republic of Tatarstan to healthy lifestyle.
