Purpose of the study. To study the intensity of lipid peroxidation (LPO) and indicators of antioxidant protection in the liver of rats of different sexes with combined pathology – the growth of Guerin's carcinoma in presence of experimental type 1 diabetes mellitus.Materials and methods. The levels of malondialdehyde (MDA) and diene conjugates (DC), the activities of superoxide dismutase (SOD) and catalase, and the levels of vitamins A and D were studied by conventional spectrophotometric methods in liver tissue samples from males and females with alloxan‑induced diabetes mellitus (DM), transplanted Guerin’s carcinoma (GC) and in animals with combined pathologies (GC growth in presence of diabetes mellitus), as well as in intact rats.Results. The levels of both LPO markers in intact females were significantly higher than in males: MDA by 3 times, DC by 2 times. The development of DM led to an increase in the content of MDA and DC in the liver of males compared with intact animals, which indicated an intensification of LPO. At the same time, there was an almost twofold increase in SOD activity, a decrease in catalase activity, and an increase in the ratio of enzymes by 2.8 times. In females, there was no increase in LPO in the liver; there was only a less pronounced increase in SOD activity than in males. At the same time, SOD activity in males was 37 % higher than in females, and catalase activity, on the contrary, was lower by 33 %, which caused a twofold excess of the ratio of enzymes in males relative to females. Among animals with GC, only males had an increase in SOD by 2.5 times, a decrease in catalase activity, and an increase in the SOD/Catalase ratio by 3 times relative to intact animals, which may be due to pronounced sex differences the SOD activity and SOD/Catalase ratio in males were 3–4 times higher than that of females. The levels of MDA and DC in males with GC growing in presence of DM remained elevated, although to a somewhat lesser extent than in DM alone, while in females both indicators were reduced. The ratio of vitamins E and A increased only in males. SOD activity and SOD/Catalase coefficient in animals of both sexes with combined pathologies were significantly lower than in groups with only DM or GC.Conclusions. The data showed that diabetes mellitus changes the specificity of oncogenesis depending on the sex of the animals. Males with the growth of Guerin's carcinoma in presence of diabetes in conditions of inhibition of SOD activity and a decrease in the ratio of conjugated enzymes of the first line of antioxidant defense demonstrate an intensification of LPO accompanied by an increase in the non‑enzymatic unit of the antioxidant system, while there is no increase in LPO in females, and the indicators of antioxidant activity change to a lesser extent.

Aim. To analyze the election programs of non-parliamentary political parties as the key documents for understanding the party ideology, assessing its attitude to the actions of the authorities, as well as the actions procedure in case of election. Research objectives: to find out if there is a correlation between the volume of the party program and its result in the elections; to establish whether the amount and quality of descriptions of initiatives are related to the results of parties in elections; and, thirdly, to characterize the party programs based on the language features of writing programs.Methodology. The analysis of the programs of the political parties "Yabloko", "Russian Party of Freedom and Justice", "Motherland", "Pensioners Party", "New People" (at the time of the elections it was a non-parliamentary party), "Communist Party of Communists of Russia", "Green", "Green Alternative", "Civil Platform" as well as the manifesto of the party "Growth", which was used by the party as an election program, was carried out. The methods of studying documents, content analysis, and a comparative method are used in the paper.Results. It has been established that the best results among non-parliamentary political parties were achieved by those whose program volume is at least 10 thousand characters. It has been revealed that the number of initiatives included in the program for the voter is as important as the quality and detail of their description, and the linguistic features, identified through the analysis of frequently mentioned within the framework of the program of words, allow to give a basic description of the document as well as to determine the ideological and political features and directions of the party.Research implications of the article is in the comparison of the program documents of the parties with the election results, which makes it possible to identify the most successful strategies for compiling political documents.

Published: June 2022

The purpose of the study was to evaluate the relationship between clinical and functional changes and sST2 levels in patients with dilated cardiomyopathy (DCM) admitted to the hospital due to decompensated chronic heart failure (CHF).	Methods and Results: The study involved 64 DCM patients with clinical signs of decompensated CHF. According to the sST2 level, the patients were divided into two groups. Group 1 included 30 patients with sST2 level <35ng/ml; Group 2 included 34 patients with sST2 level ≥35ng/ml. All patients underwent the following examinations: collection of anamnestic data, physical examination, general clinical and laboratory blood tests, 12-lead ECG, conventional 2D echocardiography in M- and B-modes, the 6MWT, and the assessment of the quality of life according to the Minnesota Living with Heart Failure Questionnaire (MLHFQ). The serum level of sST2 was determined by enzyme immunoassay using the Presage ST2 Assay.	The duration of CHF was significantly longer in Group 2 than in Group 1(48.7±6.5 mth versus 29.6±7 mth P<0.05), and the number of hospitalizations per year was more frequent. Group 2 patients were characterized by lower blood pressure levels and high heart rate (P<0.05). At the same time, the 6MWT value was lower and MLHFQ score was higher in Group 2 than in Group 1 (P<0.001 in both cases). In Group 1, LVEF was significantly higher and LVM was significantly lower than in Group 2 (P<0.001). All in all, Group 2 patients had more pronounced disorders in LV systolic dysfunction. The correlation analysis revealed an inverse correlation between the sST2 level and 6MWT (r=-0.69, P<0.01), as well as LVEF (r=-0.26, P<0.01). Statistically significant direct correlations were found between the sST2evel and the size and volume of the LV cavities.	Conclusion: sST2 is a clinically relevant biomarker that reflects pathophysiological processes and provides prognostic information in the setting of DCM, especially in patients with HF.

Published: June 2022

Background: SARS-Cov-2, a new strain of coronavirus first identified in Wuhan city, China, has spread worldwide, causing severe illnesses and a high mortality rate. Many studies have shown the association of elevated levels of pro-inflammatory markers, such as ferritin and C-reactive protein (CRP), with the severe course of coronavirus disease The aim of this research was to investigate the association between CRP and ferritin levels, and the severity of COVID-19.	Methods and Results: This cross-sectional study was performed in Thumbay Hospital, Ajman, United Arab Emirates, from January 2021 to October 2021. A total of 100 COVID-19 positive patients were included in this study. Serum CRP and ferritin were measured by immunoturbidimetric assay. We found statistically significant differences between ferritin levels and disease severity (P=0.005), age category (P=0.030), and the clinical wards (P=0.016). Statistically significant differences were found between the ferritin levels in mild to moderate cases (P=0.023) and mild to severe cases (P=0.007). There were significant differences in CRP in mild to moderate cases (P=0.012), and in mild to severe cases (P=0.000). Thus, the results obtained showed that CRP and ferritin levels are considerably greater in severe cases than in mild and moderate cases of COVID-19. The findings of the current study indicate that CRP and serum ferritin levels might be considered as an essential indication of the progression and severity of COVID-19.

Abstract
Background: Hyperbilirubinemia (HB) is a serious complication in aortic arch surgery, which is associated with acute kidney injury (AKI). The association between HB and chronic kidney disease (CKD) is unknown. The aim of this study was to investigate the impact of HB associated AKI on CKD after aortic arch surgery.Methods: We reviewed 284 patients who underwent aortic arch surgery from 2016 to 2020 in our hospital. AKI was defined as a 50% increase in sCr from baseline value within the first 7 postoperative days. HB was defined as total bilirubin >51.3 μmol/L. Patients were divided into 3 groups based on AKI and HB: HB associated AKI (HB-AKI) group (AKI patients suffered HB within the first 7 postoperative days); AKI without HB group and Non-AKI group. Results: Follow-up for 204 patients ranged from 3 to 12 months. Kaplan–Meier analysis showed that the 1-year cumulative incidence of CKD was highest in HB-AKI (32.6%) than AKI without HB (17.8%) and Non-AKI (7.4%, log-rank test, p<0.001), and the incidence of CKD was higher in HB group than that in Non-HB group (26.7% vs. 13.9%, log-rank test, p=0.015). Preoperative sCr (HR 1.010, 95% CI 1.004-1.016，p=0.001), AKI without HB (HR 2.887, 95% CI 1.133-7.354, p=0.026) and HB-AKI (HR 4.490, 95% CI 1.59-12.933, p=0.005) were associated with CKD during 1-year follow-up.Conclusions: Patients suffering HB associated AKI were at more increased odds of CKD than patients suffering AKI without HB after aortic arch surgery.

Abstract
Background
Valve replacement surgery with mechanical or biological prostheses is associated with a risk of thromboembolism and hemorrhagic complications related to complementary anticoagulation therapy. Current American and European treatment guidelines have established recommendations for the choice of heart valve prosthesis and the corresponding optimal anticoagulation therapy. The present study focuses on the presence of the abovementioned complications as well as on determining the probability of their risk.
Methods
We studied a cohort of 163 patients who underwent valve replacement surgery from 2002 to 2016 with either mechanical or biological prostheses. Both groups were treated with vitamin K agonist (VKA) complementary anticoagulation therapy after hospital discharge. Anticoagulation therapy was categorized into either optimal or not optimal according to the international normalized ratio (INR) values prior to the development of complications. Patients with comorbidities and other risk factors for thrombosis and/or bleeding were excluded.
Results
A total of 68.7% of patients underwent valve replacement with a mechanical prosthesis, and 31.3% were subjected to valve replacement with a biological prosthesis (p ≤ 0.001). Of those who received mechanical prostheses, 72.3% were younger than 60 years, and 27.7% were older than 60 years (p ≤ 0.001). Twenty-five percent of the patients had complications during the study (p ≤ 0.001), but their incidence was not associated with age (68.3% ≤ 60 years; p = 0.59). Hemorrhagic complications were the most common, observed in 48.8% of patients, followed by thromboembolic complications, seen in 26.8% of patients; both types of complications were noted in 24.4% of patients (RR 4.229 [CI 1.122-15.933]). Of the patients with complications, 95.1% received mechanical prostheses, and 4.9% received biological prostheses (p = 0.005). Among all patients who received prostheses, 49.7% had a nonoptimal INR; of these patients, 88.9%, had mechanical prostheses and 11.1% had biological prostheses (p ≤ 0.001).
Conclusions
Because of the high risk of thromboembolic and hemorrhagic complications, valve prostheses should be chosen carefully, and the priority of care should include prevention and follow-up, primarily for in patients requiring anticoagulation therapy.
