Background: The prevalence of obesity is rising dramatically worldwide. Recently, there is increasing evidence linking obesity with the functional state of the intestinal microbiota. The understanding of this relationship may provide new approaches to the treatment of obesity by manipulating the qualitative and quantitative parameters of intestinal bacterial-fungal associations., Aim: To study the features of the qualitative and quantitative composition of the colon microbiota and to evaluate associations with anamnestic, anthropometric and biochemical parameters in young obese patients., Materials and Methods: A single-center, cross-sectional, single-stage, controlled study was conducted with the participation of 118 young people, of whom 87 were obese, and 31 people with normal body weight formed the control group. All participants underwent a biochemical blood test (total cholesterol, high-density lipoproteins, low-density lipoproteins, very low-density lipoproteins, triglycerides, uric acid, glucose, glycated hemoglobin, C-reactive protein), as well as an assessment of the state of the colon microbiota using polymerase chain reaction in real time using a set of Colonoflor-16 (premium) reagents. The Microsoft Excel 2010 and IBM SPSS Statistics 26.0 application software package was used for statistical calculations. The results were evaluated as statistically significant at a level of p<0.05., Results: Analyzing the result of Colonoflor-16 premium, the discrepancy between the obtained data of the control group and the reference values of the analysis was revealed. There was a clear tendency to decrease the content of Lactobacillus spp and Bifidobacterium spp in the obesity group. In addition, in comparison with the control group (10.3%), in the obesity group Fusobacterium nucleatum significantly prevailed (37.6%) (p=0.005), with a significant decrease in the bacteria Faecalibacterium prausnitzii (p=0.030), and an increase in the bacteria Prevotella spp (p=0.029). A lot of associations of representatives of the colon microbiota with the most important anamnestic, anthropometric and biochemical parameters were revealed in young obese patients., Conclusion: There is a redistribution of microbiota phylotypes characterized by a decrease in apathogenic microorganisms and the appearance and increase of opportunistic and pathogenic microorganisms, which generally indicates the formation of the pro-inflammatory potential of dominants and associates in young obese patients. The presence of statistically significant correlations strongly indicates of existence of close and diverse relationships between the quantitative and qualitative parameters of the microbiota and the metabolic parameters of patients.

Cardiovascular diseases are the most common complications of type 2 diabetes mellitus (T2DM) and remain the main cause of mortality in this category of patients. Currently, there is more and more data that confirm the influence of nutritional factors not only on the achievement of target values of metabolic parameters in diabetes, but also on predictors of cardiovascular risk, and also demonstrate their role as independent predictors. In this regard, the study of the role of nutritional factors in the formation of high cardiovascular risk in patients with T2DM is of high practical importance and relevance. The aim was to assess the role of nutritional factors in the formation of high total cardiovascular risk in patients with T2DM. Material and methods . An open clinical controlled prospective observation was carried out for one year in 110 patients with T2DM (87 women and 23 men, mean age 56.7±8.6 years). The average value of glycated hemoglobin (HbA1c) in the group was 8.95±2.09%, the av erage value of the body mass index was 32.3±6.2 kg/m 2 . All patients were assessed for traditional cardiovascular risk factors, markers of systemic inflammation and endothelial dysfunction, nutritional status was assessed by analyzing the frequency of consumption and a general semi-quantitative assessment of the intake of nutrients, food groups, and energy. During a one-year prospective follow-up, total cardiovascular endpoints were recorded and the effect of patient education on metabolic parameters, nutritional factors, and cardiovascular risk was assessed. Results . In patients with T2DM who had various clinical forms of cardiovascular diseases, the diet had an increased level of fats, which exceeded the intake in individuals without complications (p=0.013), and saturated fatty acids (SFA) (p=0.003). The risk of developing cardiovascular events in patients with T2DM increased by 5 times under excessive consumption of products containing SFA (meat, animal fats, sausages) (OR 5.34; CI 3.05-10.22, p=0.001). The decrease in body weight in the target range (by 7-10% during the year) was characterized by a decrease in the HbA1c by 11.9%, postprandial glycemia by 25.7%, total cholesterol by 20.4%, atherogenic coefficient by 25.0%, plasminogen activator inhibitor-1 by 8.5%, highly sensitive C-reactive protein by 27.4%, systolic blood pressure by 6.9%, and also was accompanied by significant decrease in unfavorable total cardiovascular events during the year (p=0.024). In addition, in the group of patients who underwent training, there was a decrease in the total amount of calories consumed (p=0.018), consumption of SFA (p=0.021) and mono- and disaccharides (p=0.001), an increase in dietary fiber in the diet (p=0.015). Conclusion . In the course of the study, an imbalance in the nutritional components of the diet in patients with T2DM was revealed. The significant role of alimentary factors in the formation of high cardiovascular risk has been demonstrated, as well as the effectiveness of therapeutic education of patients in terms of managing behavioral risk factors., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)

Aim. To estimate the efficacy and prognostic value of individual consulting in Far North inhabitants during a 5 year survey. Materials and methods. 125 patients with metabolic syndrome were included in the study (24.8% women, 24.8% men, age median 45 years (39-48); p > 0.05). All the participants were divided into 2 groups dependence on the consulting frequency in the framework of the non-surgical body mass reduction programs (group 1 - single consulting, group 2 - repeated consultings in 12 months). Results. Individual consulting of patients with MS within 3 months after the onset of the study allowed the target body mass to be achieved in 50% of the patients in association with the reduction of atherogenic lipid fractions (p < 0,05), insulin resistance (p < 0,05), inflammation markers, hemostasis disorders markers (p < 0,05) and decrease in the number of patients with behavioral risk factors. Repeated educational module increased the relative probability 1,9 (95% CI 1,03-3,6) and odds ratio - 2.4 (95% CI 1,01-5,4) of body mass maintenance within 24 months and also reduced the risk of type 2 DM development (Cox's F-Test: F = 2,7; p = 0,041) and atherogenicity of lipid profile after 5 year observations. Conclusion. Our results proves the necessity of active utilization of educational modules at least as often as once a year. For the successful use of these modules based at outpatient facilities of the Far North it is necessary to include a dietologist in the staff of prophylactic departments which encounters difficulty under the modern funding mode.

The aim of the work was to analyze education technologies efficacy using group methods of prevention (body mass correction school) in patients with overweight and obesity, living in Extreme North, according to a 5-year prospective survey. 181 Extreme North alien inhabitants have been investigated (23.2% men, 76.8% women) with overweight and obesity. 144 of them were surveyed during 5 years. Age median was 37 (29-49) years, including men - 33 (29-43) and women - 39.5 (27.5-48) (p=0.123). All participants were divided into 2 groups depending on preventive group education compliance. Group 1 received brief recommendations for the inspection, Group 2 was trained with the group of preventive counseling. Within 3 months of surveillance target body mass reduction was achieved by 11.3% of patients of the group 1 and 31.5% of patients of the group 2 (p=0.0018). By the end of the first year these parameters proved to be 7% and 16.4% (p=0.0453). After that there was no significant difference between groups, although about 5-6% of responders kept the achieved target of BM reduction even in group 1. Group prevention consulting is associated with short time reduction of such risk factors prevalence as low physical activity (from 86.3 to 61.1% during 3 months, p<0.005), insufficient fruits and vegetables consumption and violation of macro- and micronutrient composition of the daily diet. It is also accompanied with lower cumulative proportion of patients without all metabolic syndrome components (Cox's F-Test: F=2.61; p=0.0178) and a significant reduction of percent of patients having SCORE-risk >5% (p=0.0461) after 5 years of surveillance. Thus, group preventive consulting raises awareness of patients about their health status, leads to daily meal ratio impairment reduction, decreases prevalence of obesity and low physical activity in short time period and reduces MS - risk. During 3 months after consulting body mass reduction (of 5% or more) was observed in 30% of patients. Achieved result is stable within following 12 months in less than 16% of patients. In the longer term, education is accompanied by a decrease in MS risk and some reduction in SCORE-risk., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)

Aim: To study specific features of lipid plasm profile in patients with metabolic syndrome (MS) and manifest disorder of carbohydrate metabolism (CM) as well as their relationships with clinical symptoms of MS., Materials and Methods: Contents of lipids and apolipoproteins of plasm was measured on an empty stomach in 30 patients (18 females and 12 males) with MS and manifest disorder of CM (diabetes mellitus type 2 at the stage of good and satisfactory compensation of CM without terminal complications)., Results: The patients were found to have a subnormal level of HDLP cholesterol, high levels of total cholesterol, LDLP cholesterol and LP alpha. Hypertriglyceridemia occurred only in 31.4% patients (TG < 200 mg/dl). Mean TG level was 173.69 +/- 21.52 mg/dl. TG and diastolic arterial pressure, fasting glycemia and waist circumference significantly correlated. If the WC/TC was 1.0 and higher, the antiatherogenic plasm factor--HDLP cholesterol--significantly lowered. Positive correlation existed between TG and total cholesterol, LDLP cholesterol, apoB, LDLP cholesterol/HDLP cholesterol, apoB/apoA1, while negative correlation was seen between TG and HDLP cholesterol levels. Patients with hypertriglyceridemia had significantly higher levels of total cholesterol, LDLP cholesterol, apoB, apoB/apoA1., Conclusion: Plasm levels of TG most significantly reflect severity of basic clinical manifestations of MS: abdominal obesity, arterial hypertension, CM compensation. The presence of hypertriglyceridemia in MS patients can be considered as an indicator of high atherogenic potential of plasm.

Specific features of lipid plasma spectrum and principal parameters of red cell membranes are characterized in patients with metabolic syndrome (MS) and chronic stable ischemic heart disease (IHD). 109 patients with metabolic syndrome (diabetes mellitus type 2, arterial hypertension, abdominal obesity and dyslipidemia) were divided into 2 groups: with and without IHD. MS patients with IHD had marked defects of lipid metabolism with hypercholesterolemia, high levels of triglycerides, LDLP cholesterol, low level of HDLP cholesterol. Lipid plasma spectrum in MS patients with IHD vs those without coronary atherosclerosis was characterized by a significantly lower level of apo A1. In red cell membranes these patients had lower fractions of esterified cholesterol combined with high intensity of lipid peroxidation.

Aim: To evaluate changes in oxidative lipid metabolism in platelet membranes by content of lipid peroxidation (LPO) products and antioxidant defense (AOD) activity in patients with stable chronic ischemic heart disease (IHD) after single intake of animal fat or vegetable oil., Material and Methods: 30 IHD patients with stable angina of effort functional class II-III and 30 healthy controls had a single meal with animal fat or vegetable oil. Before the meal and 6 hours after it tests were performed for LPO activity and AOD in platelet membranes., Results: Patients with stable chronic IHD showed LPO activation and suppressed enzymatic and non-enzymatic AOD. Single animal fat or vegetable oil intake cause insignificant shifts in oxidative platelet metabolism in healthy controls while animal fat in IHD patients activates LPO and promotes accumulation of initial and end peroxidation products in platelet membranes. Vegetable fat in IHD patients suppresses enzyme AOD., Conclusion: Animal fat and vegetable oil as a single diet load have a prooxidant effect at the levels of platelet membranes in IHD patients but not in healthy persons.
