The Russian Federation is among countries with high cardiovascular risk. Hypercholesterolemia is a leading risk factor for the development of atherosclerotic cardiovascular diseases. To achieve low-density lipoprotein cholesterol (LDL-C) targets, such approaches as lifestyle changes and pharmacological correction, based on the use of statins, are applied. At the same time, a significant proportion of the population has moderate hypercholesterolemia and is characterized by low or moderate cardiovascular risk. Although first-line recommendations should be followed, a healthy lifestyle alone is not enough to achieve target levels of LDL-C, which means that even people with low to moderate risk may end up with the prospect of lifelong therapy with lipid-lowering drugs. These individuals do not have an indication for lipid-lowering therapy, and they are usually recommended a change in diet and supplementation. Innovative nutritional strategies have been developed to manage dyslipidemia. They were based either on changing some “risky” food components or on encouraging the consumption of “healthy” functional foods and/or nutraceuticals. Nutraceuticals (registered as food supplements in Russia) is an innovative way to help control LDL-C at low and moderate risk individuals without lipid-lowering drugs and as nutritive support for the cholesterol-lowering diet. Red yeast rice (RYR) based preparations have been already developed and available at the moment. RYR based preparations can be considered in patients with low and moderate cardiovascular risk, who have not reached the target level of LDL-C and have no indications for statin therapy or have statin intolerance. RYR based preparations contains a statin-like substance monacolin K in a dose of 3 mg. In randomized clinical trials, it was proved that the use of high-quality RYR nutraceutical leads to a decrease in LDL-C by an average of 20% without increasing the risk of side effects like for statins. Evaluation of dietary supplements and functional foods should necessarily include not only evidence of beneficial effects with respect to effects on the lipid profile and atherosclerosis, but also proven good tolerability. The manufacturing standard for these products is also important, guaranteeing component standardization and quality. RYR analogues should guarantee the absence of mycotoxin in their composition. In Russia, programs are needed for the primary prevention of atherosclerotic cardiovascular diseases with effects on hypercholesterolemia at the population level.

Neuroprotective properties of fullerenols С60(OH)30 and С70(OH)30 have been shown in a Drosophila melanogaster model of Parkinson's Disease (PD). Fullerenols used in this work demonstrated negligible toxicity even at high concentrations as a result of a specifically developed manufacturing process. It has been shown that the drugs promote restoration of dopamine levels, reduce oxidative stress in transgenic flies expressing the human alpha-synuclein gene, prevent death of dopaminergic neurons in the brain and alleviate aggregation of alpha-synuclein. Thus, the anti-aggregation effect of fullerenols, demonstrated for various forms of amyloid proteins, is also observed for alpha-synuclein, resulting in reduction of formation of insoluble aggregates of this protein. Neuroprotective activity was affected by the Drosophila melanogaster genotype and not by the number of carbon atoms in the fullerenol compounds. We concluded that due to their unique properties, fullerenols might be a promising tool for drug development to treat PD.

Aim. To evaluate the relationship between the clinical decision support system use (CDSS) and adherence to clinical guidelines.Materials and methods. Medical records of 300 patients with atrial fibrillation and hypertension from the electronic medical database of the Almazov National Medical Research Center were analyzed. Demographic and clinical data, as well as information on anticoagulant, antiarrhythmic and antihypertensive prescriptions were analyzed. The primary endpoint was adherence of prescribed treatment to current clinical guidelines for each of the three therapies. Firstly, a group of independent clinical experts assessed primary endpoint for retrospective prescriptions. Secondly, new prescriptions were simulated by another group of clinical experts using CDSS and blinded to previous therapy. Primary endpoint at the second step was analysed by independent experts. We compared adherence to relevant clinical guidelines with and without use of CDSS. Additionally, we analyzed predictors of failing to meet the current recommendations in the retrospective records.Results. Out of 300 patients, only 291 (97%) had all characteristics and were included in the analysis. In 26 patients (18%), all three treatment strategies were in accordance with current clinical guidelines. Anticoagulant therapy was adherent to the guidelines in 92% of cases. Experts who used CDSS were 15% (95% confidence interval [CI], 10-21%) more likely to prescribe novel oral anticoagulants and 14% (95% CI, 10-19%) less likely to prescribe warfarin compared to baseline. Antiarrhythmic therapy was adherent to the guidelines in 69% of cases. When the CDSS platform was applied, experts were 14% (95% CI 4-19%) more likely to prefer antiarrhythmic drug (AAD) monotherapy and 32% (95% CI 26-37%) more often prescribed radiofrequency ablation (RFA) of left atrium. At baseline, antihypertensive therapy combinations were adherent clinical guidelines in 28% of cases. The use of the CDSS platform by experts was significantly associated with an increase in the frequency of prescribing dual and triple antihypertensive therapy.Conclusion. CDSS use is associated with improved adherence to current clinical guidelines. Prospective randomized trials are needed to evaluate the CDSS effectiveness in the prevention of cardiovascular events.

Actuality . Pre-eclampsia during pregnancy is a major cause of maternal mortality, intra- and neonatal pathology [1]. Sharply there is a question about the search method of determining the predictors of pre-eclampsia and the degree of influence on a woman’s body for the purpose of timely diagnosis and treatment. Interest in the method of determining the parameters of arterial stiffness is growing every year because of the availability and relative ease of use to determine the degree of maladjustment of the vascular system and assessing the risks of cardiovascular disease. Objective. Evaluation of indicators characterizing stiffness of the arterial wall in pre-eclampsia during pregnancy and after childbirth. Materials and Methods . In a prospective cohort comparative study included 62 pregnant women aged 19 to 35: 35 women with physiological pregnancy without physical abnormalities and 27 women with preeclampsia moderate, without preeclampsia history. Surveys were carried out in time for 22-24, 32-34 weeks of gestation and at 8 hours after delivery. To evaluate the rigidity of the vascular wall used complex BPLab. Results . In pregnant women with pre-eclampsia there is an increase of arterial stiffness parameters at 22 weeks of pregnancy in comparison with the original data at 12 weeks of gestation, IA uvelichilsyana 29.3%, 12.5% PWV. Most significantly in the intervention group to the third trimester have changed the following parameters: IA averaged – - 28% (± 5,5) + 37% from baseline, PWV – 8 m/s (± 0,9) + 12,5%, in the control group: IA – - 39,6% (± 8,1) + 12,2% in comparison with the data of 12 weeks’ gestation, PWV – 7.43 m/s (± 0,82) + 12,5%, demonstrating various adaptive features of the vascular wall in groups. In the early postpartum period significantly positive dynamics of arterial stiffness parameters in the group with physiological pregnancy, pre-eclampsia in the group with the values remain the same or change slightly. Conclusions . Thus, from the data of the pulse wave analysis is the best method for measuring vascular stiffness non-invasively in pregnant women. This method demonstrates the physiological adaptation of vessels to the gestational process, and shows the changes associated with preeclampsia as the background of pregnancy and after childbirth. Thus, this method makes it possible to evaluate the adaptive reserve of the vascular wall for the purpose of forecasting the development of cardiovascular complications.

Background. Imidazoline receptor agonist moxonidine besides its antihypertensive effect, can increase insulin sensitivity, reduce leptin level, improve lipid metabolism. However, the efficacy, tolerability and pleiotropic effects of moxonidine in postmenopausal women with essential hypertension (EH) and metabolic syndrome (MS) are not well established, and it was the objective of this study. Design and methods. 30 postmenopausal women with EH and MS (52,5 ± 0,4 years old) were included. Moxonidine was administered (400-600 mkg/day) for 12 weeks. Waist circumference (WC), hip circumference (HC), WC/HC ratio, body mass index (BMI), insulin, leptin level, glucose, lipid profile of blood serum, index of insulin resistance (HOMA-IR) and index of functional activity of pancreatic beta cells (HOMA-FB), echocardiography, intima-media thickness (IMT) of common carotid arteries (CCA). Results. Moxonidine therapy was associated with blood pressure (BP) decrease, body weight and BMI decrease, high-density lipoprotein (HDL) cholesterol and HOMA-FB index increase. Left atrium diameter and volume decreased, left ventricular diastolic function improved. Conclusions. Moxonidine is an effective antihypertensive drug for the treatment of postmenopausal hypertensive women with MS, which improves a range of metabolic, hemodynamic parameters and leads to the decrease of left atrium volume and diameter.

To evaluate influence of moxonidine on serum leptin concentration, lipid and carbohydrate metabolism in hypertensive postmenopausal women with metabolic syndrome (MS). 26 hypertensive (AH grades 1–2) postmenopausal women with MS 52,5+/−0,4 years old. MS was diagnosed according to ESC-ESH (2007) criteria. Patients were treated with moxonidine (200–600 mcg/day orally) during 12 weeks. Serum leptin and plasma insulin levels were determined by ELISA. Serum lipids were defined by immunoenzymatic assay. The homeostasis model assessment (HOMA-IR and HOMA-FB) was applied to assess insulin resistance and insulin secretion. Statistical analyses were performed using SPSS 17.0 for Windows (SPSS, Inc., Chicago, IL, USA). Postmenopausal hypertensive women with MS had high level of serum leptin concentration (107,2+/−12,0 ng/ml), HDL cholesterol concentration was 1,3+/−0,09 mmol/l, glucose plasma was 5,33+/−0,10 mmol/l, HOMA-IR - 3,8+/−0,3 and HOMA-FB index was 204,7+/−30,1. Plasma glucose level >5,6 mmol/l had 8 (27%) women, dyslipidemia was revealed in 22 (84,6%) patients. HOMA-IR index elevation was revealed with 19 (73%) patients. Moxonidine therapy did not influenced serum leptin level - 107,2+/−12,0 ng/ml vs 101,4+/− 11,7 ng/ml (p = 0,06); HDL cholesterol increased from 1,3+/−0,09 mmol/l to 1,5+/−0,09 mmol/l (p < 0,05), LDL cholesterol, triglycerides and total cholesterol did not changed, HOMA-IR index did not changed, and plasma glucose level did not changed (5,33+/−0,10 mmol/l vs 5,15+/−0,13 mmol/l; p = 0,07). By the end of 12 weeks of moxonidine therapy HOMA-FB index increased from 204,7+/−30,1 to 222,3+/−27,8 (p < 0,05). In hypertensive postmenopausal women with metabolic syndrome moxonidine therapy improved some parameters of lipid composition (HDL cholesterol elevation), and increased HOMA-FB index, but serum leptin, plasma insulin and plasma glucose levels did not significantly changed.

Study Objective: To evaluate influence of moxonidine therapy on carotid wall thickness, heart structural and functional parametres in hypertensive postmenopausal women with metabolic syndrome (MS). Material and Methods: 26 hypertensive (AH grades 1–2) postmenopausal women with metabolic syndrome 45–55 years old (52,5+/−0,4 years). MS was diagnosed according to ESC-ESH (2007) criteria. Patients were treated with moxonidine (200–600 mcg/day) orally. Structure and function of the heart and the intima-media thickness of carotid arteries were reviewed by ultrasound method before therapy and on 12-th week of treatment with moxonidine. Statistical analyses were performed using SPSS 17.0 for Windows (SPSS, Inc., Chicago, IL, USA). Results: 14 (53,8%) hypertensive postmenopausal women with MS had elevated left ventricle mass index (LVMI more than 110 g/m2). 9 (34,6%) patients had LV diastolic dysfunction. We revealed correlation between LVMI, interventricular septum thickness, E/A ratio and systolic BP (r = 0,4; 0,4 and -0,4, accordingly; p = 0,02; 0,04 and 0,02 accordingly). Positive correlation was revealed between interventricular septum thickness and diastolic BP (r = 0,4; p = 0,07); left atrium diameter and diastolic BP (r = 0,4; p = 0,04). Results: Moxonidine therapy did not changed intima-media thickness of carotid arteries (0,86+/−0,03 mm vs 0,81+/−0,04 mm; p = 0,05) and LVMI (114,0+/−3,4 g/m2 and 113,9+/−3,4 g/m2, p > 0,05). LV diastolic function improved: E/A ratio increased from 1,05+/− 0,03 to 1,20+/− 0,03 (p Conclusion: Moxonidine therapy improved left ventricle diastolic function and decreased left atrium diameter and left atrium volume in hypertensive postmenopausal women with metabolic syndrome.

The issue of providing reliable, safe and at the same time least invasive venous access remains one of the topical issues of oncology. Installation of venous access for patients with oncological pathology is necessary for chemotherapy, blood sampling for analysis, as well as for palliative and symptomatic care for patients which has advanced stages of malignant process. Therapeutic agents can be administered in various ways: intra-arterially, intravenously, intraperitoneally. In the world of modern medicine, intravenous administration of drugs is most often used, since it provides a high rate of spread, as well as systemic action in the human body. However, not all medicinal substances are amenable to easy and safe delivery by parenteral route and, first of all, it concerns cytostatic agents. Chemotherapy has an irritating and sometimes damaging effect on the walls of peripheral vessels, and frequent blood fetuses and the introduction of parenteral chemotherapeutic agents entail complications in the form of phlebitis, thrombophlebitis and other septic processes that can lead to death. Despite the fact that the port system was invented more than 50 years ago, this device is increasingly used in the daily clinical practice of an oncologist and doctors of other specialties, including anesthesiology and pediatrics. So the port system is a small device which is placed under the skin under local anesthesia to perform certain medical manipulations related to the treatment and diagnosis of diseases. This article provides arguments on the appropriateness of using the subcutaneous venous port system, its advantages, disadvantages, as well as the features of its installation, exploitation and also their importance in the modern clinical medicine.

The Russian Federation is among countries with high cardiovascular risk. Hypercholesterolemia is a leading risk factor for the development of atherosclerotic cardiovascular diseases. To achieve low-density lipoprotein cholesterol (LDL-C) targets, such approaches as lifestyle changes and pharmacological correction, based on the use of statins, are applied. At the same time, a significant proportion of the population has moderate hypercholesterolemia and is characterized by low or moderate cardiovascular risk. Although first-line recommendations should be followed, a healthy lifestyle alone is not enough to achieve target levels of LDL-C, which means that even people with low to moderate risk may end up with the prospect of lifelong therapy with lipid-lowering drugs. These individuals do not have an indication for lipid-lowering therapy, and they are usually recommended a change in diet and supplementation. Innovative nutritional strategies have been developed to manage dyslipidemia. They were based either on changing some “risky” food components or on encouraging the consumption of “healthy” functional foods and/or nutraceuticals. Nutraceuticals (registered as food supplements in Russia) is an innovative way to help control LDL-C at low and moderate risk individuals without lipid-lowering drugs and as nutritive support for the cholesterol-lowering diet. Red yeast rice (RYR) based preparations have been already developed and available at the moment. RYR based preparations can be considered in patients with low and moderate cardiovascular risk, who have not reached the target level of LDL-C and have no indications for statin therapy or have statin intolerance. RYR based preparations contains a statin-like substance monacolin K in a dose of 3 mg. In randomized clinical trials, it was proved that the use of high-quality RYR nutraceutical leads to a decrease in LDL-C by an average of 20% without increasing the risk of side effects like for statins. Evaluation of dietary supplements and functional foods should necessarily include not only evidence of beneficial effects with respect to effects on the lipid profile and atherosclerosis, but also proven good tolerability. The manufacturing standard for these products is also important, guaranteeing component standardization and quality. RYR analogues should guarantee the absence of mycotoxin in their composition. In Russia, programs are needed for the primary prevention of atherosclerotic cardiovascular diseases with effects on hypercholesterolemia at the population level.

- Abstract
Carbon nanoparticles with antimicrobial properties, such as fullerenes, can be distinguished among the promising means of combating pathogens characterized by resistance to commercial antibiotics. However, they have a number of limitations for their use in medicine. In particular, the insolubility of carbon nanoparticles in water leads to a low biocompatibility and especially strong aggregation when transferred to liquid media. To overcome the negative factors and enhance the action of fullerenes in an extended range of applications, for example, in antimicrobial photodynamic therapy, we created new water-soluble complexes containing, in addition to C60 fullerene, purified detonation nanodiamonds (AC960) and/or polyvinylpyrrolidone (PVP). The in vitro antibacterial activity and toxicity to human cells of the three-component complex C60+AC960+PVP were analyzed in comparison with binary C60+PVP and C60+AC960. All complexes showed a low toxicity to cultured human skin fibroblasts and ECV lines, as well as significant antimicrobial activity, which depend on the type of microorganisms exposed, the chemical composition of the complex, its dosage and exposure time. Complex C60+PVP+AC960 at a concentration of 175 µg/mL showed the most stable and pronounced inhibitory microbicidal/microbiostatic effect.

- Abstract
Abstract: Voltage-gated Ca2+ channels play a key role in the regulation of arterial tone and blood pressure. The aim of this study was to determine whether the association of calcium voltage-gated channel subunit alpha1 C (CACNA1C) rs1006737 with essential hypertension (EH) exists in both Chinese Han and ethnic Russian populations of Northeast Asia. We used a case-control study of 2 ethnic groups in the same latitude geographical area to investigate the association between the susceptibility of EH and rs1006737 polymorphism. A total of 1512 EH patients and 1690 controls in Chinese Han people (Heilongjiang Provence, China), 250 EH patients, and 250 controls in ethnic Russian people (Chita, Russia), participated in this study. All participants were genotyped using the TaqMan SNP genotyping assay (Agena Company). Baseline characteristics and the minor allele frequencies of rs1006737 vary substantially among common Chinese Han and ethnic Russian people. Allele A was found to be a risk factor for EH in Chinese Han [(odds ratio) OR 1.705, (confidence interval) 95% CI: 1.332-2.182, P < .001] and ethnic Russian (OR 1.437; 95% CI: 1.110-1.860, P = .006). The GA genotype was significantly associated with an increased risk of hypertension (OR 1.538, 95% CI: 1.188-1.991, P = .001) for Chinese Han people, and the AA genotype (OR 2.412, 95% CI: 1.348-4.318, P = .003) for ethnic Russian people. The results of this study indicate that the A allele of the variant rs1006737 in the CACNA1C gene may be a useful genetic marker for EH risk prediction in Chinese Han and ethnic Russian populations., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 the Author(s).

- Abstract
Neuroprotective properties of fullerenols С
60 (OH)30 and С70 (OH)30 have been shown in a Drosophila melanogaster model of Parkinson's Disease (PD). Fullerenols used in this work demonstrated negligible toxicity even at high concentrations as a result of a specifically developed manufacturing process. It has been shown that the drugs promote restoration of dopamine levels, reduce oxidative stress in transgenic flies expressing the human alpha-synuclein gene, prevent death of dopaminergic neurons in the brain and alleviate aggregation of alpha-synuclein. Thus, the anti-aggregation effect of fullerenols, demonstrated for various forms of amyloid proteins, is also observed for alpha-synuclein, resulting in reduction of formation of insoluble aggregates of this protein. Neuroprotective activity was affected by the Drosophila melanogaster genotype and not by the number of carbon atoms in the fullerenol compounds. We concluded that due to their unique properties, fullerenols might be a promising tool for drug development to treat PD., (Copyright © 2019 Elsevier Inc. All rights reserved.)- Published

- Abstract
The toxicity of C
60 (OH)30 , C70 (OH)30 , and C120 O(OH)n fullerenols, prepared by a new original method, has been studied. This method allowed us to obtain high-purity fullerenols and eliminate the risks of synthesis of preparations containing insoluble fractions contaminated with impurities such as fullerenes not completely reacted by hydroxylation. All fullerenols were detected inside cultured cells. The MTT assay as well as the analysis of apoptosis and cell cycle showed that С60 (ОН)30 and С70 (OH)30 are non-toxic for cultured V79 и HeLa cells at concentrations exceeding physiological levels by an order of magnitude. С120 O(OH)n caused low toxicity. Studies in Drosophila melanogaster showed that any preparations used did not result in a decreased lifespan or in behavior abnormalities in flies., (Copyright © 2019 Elsevier B.V.

- Abstract
Background: Mutations of the amyloid precursor protein gene (APP) are found in familial forms of Alzheimer's disease (AD) and some lead to the elevated production of amyloid-beta-protein (Abeta). While Abeta has been implicated in the causation of AD, the exact role played by Abeta and its APP precursor are still unclear., Principal Findings: In our study, Drosophila melanogaster transgenics were established as a model to analyze AD-like pathology caused by APP overexpression. We demonstrated that age related changes in the levels and pattern of synaptic proteins accompanied progressive neurodegeneration and impairment of cognitive functions in APP transgenic flies, but that these changes may be independent from the generation of Abeta. Using novel peptide mimetics of Apolipoprotein-E, COG112 or COG133 proved to be neuroprotective and significantly improved the learning and memory of APP transgenic flies., Conclusions: The development of neurodegeneration and cognitive deficits was corrected by injections of COG112 or COG133, novel mimetics of apolipoprotein-E (apoE) with neuroprotective activities.
