Atrial fibrillation recurrence after catheter ablation is associated with RAD51 and p63 proteins. Heliyon 2024; 10:e32874. [PMID: 38988509 PMCID: PMC11233995 DOI: 10.1016/j.heliyon.2024.e32874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 06/06/2024] [Accepted: 06/11/2024] [Indexed: 07/12/2024] Open
Abstract
Catheter ablation has been demonstrated to reduce atrial fibrillation (AF) recurrence. The mechanisms of AF recurrence after catheter ablation are unknown, and the present study aimed to identify serum proteins associated with AF recurrence. The present prospective study comprised a cohort of patients with AF, which was divided into two groups after one-year follow-up: group 1 included patients with compensated AF after catheter ablation and group 2 included patients with AF recurrence after catheter ablation. Initial microarray profiling of the serum proteins was performed in small subgroups M1 and M2 recruited from groups 1 and 2, respectively, by an antibody microarray to evaluate potentially relevant proteins. The data of initial proteomic profiling identified candidate proteins in groups 1 and 2, and their levels were then measured by ELISA. The data of profiling suggested an overall increase in the levels of RAD51 and p63 proteins in the M2 subgroup versus that in the M1 subgroup, indicating potential relevance of these two proteins to AF recurrence. The results of ELISA of the levels of RAD51 and p63 in the groups 1 and 2 demonstrated an increase in the levels of RAD51 (11.11 ± 4.36 vs 8.45 ± 4.85 ng/mL; P = 0.009) and p63 (165.73 ± 113.75 vs 100.05 ± 37.56 units of normalized optical density; P = 0.0007) in the group 2 (with AF recurrence or substrate AF) compared with that in the group 1 (compensated AF). Thus, RAD51 and p63 were associated with AF recurrence after catheter ablation and may represent possible etiological factors for subsequent outcomes.

Abstract
SCORE2 (Systematic COronary Risk Evaluation 2) is a risk assessment scale for cardiovascular events, presented in 2021 by the European Society of Cardiology. Both for training and validation of the SCORE2 model, representative samples from the Russian population were not used. Therefore, we aimed to validate SCORE2 on a such sample. For this purpose, we used a sample from the ESSE-RF epidemiological study consisting of 7251 participants aged 40-69 years without history of CVDs. We performed the validation by comparing SCORE2 risk estimates for ESSE-RF participants with the observed incidence of cardiovascular events in the study, adjusted for event information losses. The validation demonstrated that SCORE2 risk estimates were accurate for Russian men and inaccurate for Russian women. Together with the quantitative assessment of risk, SCORE2 offers its interpretation in terms of 10-year CVD risk group: low-moderate, high, and very high. For Russian men we considered the original interpretation of the SCORE2 estimates to be questionable because almost none of the men would be categorized as having "low-to-moderate" 10-year CVD risk. This problem would be typical for all countries of the very high CVD risk region. Therefore, we proposed a new interpretation of the SCORE2 risk estimates for men from the very high risk region. According to the proposed interpretation, the fraction of men in ESSE-RF in "low-to-moderate" 10-year CVD risk increased from 2% to 18% and the fraction of men in "very high" CVD risk decreased from 63% to 20% as compared to the original interpretation. The proposed interpretation would allow a more personalized approach to CVD treatment and optimize the burden on primary healthcare in the very high risk region countries.

Abstract
Aim To identify independent predictors associated with in-hospital atrial fibrillation (AF) following coronary artery bypass grafting (CABG).Material and methods The study included 80 patients (88.75 % men) who had elective CABG surgery at the Sklifosovsky Research Institute of Emergency Medicine. Based on the development of AF during the hospital stage of treatment (up to 10 days after CABG surgery), patients were divided into two groups. The group with AF consisted of 19 patients, and the group without AF consisted of 61 patients. All patients underwent electrocardiography (ECG), transthoracic echocardiography (EchoCG) with calculation of the left ventricular (LV) geometry type, and assessment of operational indexes. During surgery, biopsy of a part of the right atrial (RA) appendage was taken from 61 patients to verify the severity of myocardial fibrosis on a four-score scale where 0 is no interstitial fibrosis, 1 is slight fibrosis, 2 is moderate fibrosis, and 3 is severe fibrosis.Results All included patients had a low risk of developing postoperative complications according to the EuroSCORE II scale. According to EchoCG data, patients with AF had significantly higher ratios of left ventricular myocardial mass to body surface area (LVMM / BSA) (p = 0.0006) and of left atrial volume to body surface area (LA volume / BSA), p = 0.008). The distribution of patients by type of LV geometry was as follows: in the group with AF, 52.63 % (n=10) of patients were diagnosed with concentric LV hypertrophy (LVH) whereas in the group without AF, the majority of patients (83.60 %, n=51) had normal LV geometry and concentric LV remodeling (LVR) (p<0.0001). According to the results of histological study, patients of the AF group more frequently had moderate and severe interstitial fibrosis in the AF appendage (p = 0.003). After multivariate regression and ROC analysis, the predictive value remained for concentric LVH (p=0.002), LVMM / BSA ratio ≥97 g / m2 (p=0.006), LA volume / BSA ratio ≥ 34.4 ml / m2 (p=0.04), and for RA appendage interstitial fibrosis score ≥2 (p=0.004). Based on the identified predictors, a regression model was developed to predict the development of AF at the hospital stage after CABG (p<0.0001). The sensitivity and specificity of the model were 86.67 % and 78.26 %, respectively.Conclusion In patients at low perioperative risk, the LVMM / BSA ratio ≥97 g / m2, the LA volume ratio / BSA ≥34.4 ml / m2, a RA appendage interstitial fibrosis score ≥2, and the presence of LVH were independent predictors of the development of AF at the hospital stage after CABG operation.Conclusion In patients at low perioperative risk, a LVMM / BSA ratio ≥97 g / m2, a LA volume / BSA ratio ≥34.4 ml / m2, a RA appendage interstitial fibrosis score ≥2, and the presence of LVH were independent predictors of the development of AF at the hospital stage after CABG.

Abstract
Heat shock proteins (HSPs), a family of proteins that support cellular proteostasis and perform a protective function under various stress conditions, such as high temperature, intoxication, inflammation, or tissue hypoxia, constitute a promising group of possible biochemical markers for obesity and cardiovascular diseases. HSP27 is involved in essential cellular processes occurring in conditions of obesity and its cardiometabolic complications; it has protective properties, and its secretion may indicate a cellular response to stress. HSP40 plays a controversial role in the pathogenesis of obesity. HSP60 is involved in various pathological processes of the cardiovascular, immune, excretory, and nervous systems and is associated with obesity and concomitant diseases. The hypersecretion of HSP60 is associated with poor prognosis; hence, this protein may become a target for further research on obesity and its cardiovascular complications. According to most studies, intracellular HSP70 is an obesity-promoting factor, whereas extracellular HSP70 exhibited inconsistent dynamics across different patient groups and diagnoses. HSPs are involved in the pathogenesis of cardiovascular pathology. However, in the context of cardiovascular and metabolic pathology, these proteins require further investigation.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is considered the most common chronic liver disease worldwide, affecting nearly 25% of the global adult population. Increasing evidence suggests that functional and compositional changes in the gut microbiota may contribute to the development and promote the progression of NAFLD. 16S rRNA gene next-generation sequencing is widely used to determine specific features of the NAFLD microbiome, but a complex system such as the gut microbiota requires a comprehensive approach. We used three different approaches: MALDI-TOF-MS of bacterial cultures, qPCR, and 16S NGS sequencing, as well as a wide variety of statistical methods to assess the differences in gut microbiota composition between NAFLD patients without significant fibrosis and the control group. The listed methods showed enrichment in Collinsella sp. and Oscillospiraceae for the control samples and enrichment in Lachnospiraceae (and in particular Dorea sp.) and Veillonellaceae in NAFLD. The families, Bifidobacteriaceae, Lactobacillaceae, and Enterococcaceae (particularly Enterococcus faecium and Enterococcus faecalis), were also found to be important taxa for NAFLD microbiome evaluation. Considering individual method observations, an increase in Candida krusei and a decrease in Bacteroides uniformis for NAFLD patients were detected using MALDI-TOF-MS. An increase in Gracilibacteraceae, Chitinophagaceae, Pirellulaceae, Erysipelatoclostridiaceae, Muribaculaceae, and Comamonadaceae, and a decrease in Acidaminococcaceae in NAFLD were observed with 16S NGS, and enrichment in Fusobacterium nucleatum was shown using qPCR analysis. These findings confirm that NAFLD is associated with changes in gut microbiota composition. Further investigations are required to determine the cause-and-effect relationships and the impact of microbiota-derived compounds on the development and progression of NAFLD.

Abstract
BACKGROUND Given the current trends in increasing the life expectancy of patients with ulcerative colitis (UC), the study of the risk of atherothrombotic events in them requires study. For effective prevention of cardiovascular diseases, it is necessary to assess cardiovascular risk factors since the concept of their timely detection is the basic one when planning preventive measures. AIM To assess the prevalence of cardiovascular risk factors in patients with UC. MATERIALS AND METHODS One hundred eighty four UC patients participated in the case-control study; 56 participants were included in the control group. The studied parameters are unmodified, behavioral, and biological factors of cardiovascular risk. The study participants were surveyed, examined, measured blood pressure, height, weight, the level of total cholesterol was studied, and the lipid spectrum was analyzed in 80 patients with UC. Parametric and nonparametric statistical methods were used. RESULTS UC patients consumed fruit less often, drank tea and coffee with sugar more often, exercised less often and experienced high levels of stress. A higher incidence of arterial hypertension in UC patients was established, even though the fact of taking glucocorticosteroids was considered. No significant differences were found in the assessment of relative and total cardiovascular risk. CONCLUSION Risk management of cardiovascular diseases in UC patients should focus on a personalized approach and timely screening of modifiable cardiovascular risk factors with their subsequent correction. The absence of significant differences in the level of relative and total cardiovascular risk indicates a limited contribution of traditional risk factors to the development of cardiovascular diseases in UC patients.

Abstract
Non-alcoholic fatty liver disease (NAFLD) and arterial hypertension (AH) are widespread noncommunicable diseases in the global population. Since hypertension and NAFLD are diseases associated with metabolic syndrome, they are often comorbid. In fact, many contemporary published studies confirm the association of these diseases with each other, regardless of whether other metabolic factors, such as obesity, dyslipidemia, and type 2 diabetes mellites, are present. This narrative review considers the features of the association between NAFLD and AH, as well as possible pathophysiological mechanisms.

Abstract
Familial dysbetalipoproteinemia (FD) is a highly atherogenic genetically based lipid disorder with an underestimated actual prevalence. In recent years, several biochemical algorithms have been developed to diagnose FD using available laboratory tests. The practical applicability of FD diagnostic criteria and the prevalence of FD in Russia have not been previously assessed. We demonstrated that the diagnostic algorithms of FD, including the diagnostic apoB levels, require correction, taking into account the distribution of apoB levels in the population. At the same time, a triglycerides cutoff ≥ 1.5 mmol/L may be a useful tool in identifying subjects with FD. In this study, a high prevalence of FD was detected: 0.67% (one in 150) based on the ε2ε2 haplotype and triglycerides levels ≥ 1.5 mmol/L. We also analyzed the presence and pathogenicity of APOE variants associated with autosomal dominant FD in a large research sample.

Abstract
Familial hypercholesterolemia (FH) is a highly atherogenic, genetically based lipid disorder. For patients with FH, dietary modification is the cornerstone of complex lipidlowering therapy. The aim of the research was to assess the actual nutrition in adults with familial hypercholesterolemia. Material and methods. The study included 100 patients over 18 years old (including 46% men) with "probable" or "definite" FH according to the Dutch Lipid Clinic Network or Simon Broome criteria from the GENMOTIV-FH study (ClinicalTrials: NCT04656028) in 2019-2021. Actual nutrition was assessed using the 24-hour dietary recall method. The frequency of the main meal groups' consumption and food-related behavior were assessed using a questionnaire method. The data are presented as the median [Q25; Q75]. Results. The study showed the excess consumption of protein (19.3 [16.7; 24.0] in men and 18.6% [13.6; 24.3] in women, p=0.592), total fat (35.1 [29.4; 41.0] in men vs 39.2% [33.2; 47.5] in women, p=0.018), including saturated fatty acids (9.6 [4.7; 13.0] vs 10.4% [7.5; 14.2], respectively, p=0.151), and cholesterol (265.8 [188.8; 521.9] mg/day in men vs 282.1 [147.2; 542.8] mg/day in women, p=0.936). Consumption of total carbohydrates (44.3 [37.2; 50.0] vs 39.6% [30.1; 48.8], respectively, p=0.100) and fiber (10.7 [7.3; 13.3] g/day in men vs 11.5 [7.9; 13.9] g/day in women, p=0.372) was insufficient. Only 47.9% of patients consumed vegetables daily, 39.1% - fruits and berries. The majority (64.5%) of patients with FH preferred high-fat cheese (>=25%). Cottage cheese of >=5% fat content preferred 52.7% of patients. The daily poultry consumption was more than red meat (19.3 vs 4.3% respectively, p=0.003). Regularly included fish in their meal 53.8% of patients. Conclusion. The actual nutrition in adults with FH does not match international guidelines. The results highlight the importance of dietary interventions for patients with FH.

Abstract
Increasing evidence suggests that skeletal muscles may play a role in the pathogenesis of obesity and associated conditions due to their impact on insulin resistance and systemic inflammation. Skeletal muscles, as well as adipose tissue, are largely recognized as endocrine organs, producing biologically active substances, such as myokines and adipokines. They may have either beneficial or harmful effects on the organism and its functions, acting through the endocrine, paracrine, and autocrine pathways. Moreover, the collocation of adipose tissue and skeletal muscles, i.e., the amount of intramuscular, intermuscular, and visceral adipose depots, may be of major importance for metabolic health. Traditionally, the generalized and progressive loss of skeletal muscle mass and strength or physical function, named sarcopenia, has been thought to be associated with age. That is why most recently published papers are focused on the investigation of the effect of obesity on skeletal muscle function in older adults. However, accumulated data indicate that sarcopenia may arise in individuals with obesity at any age, so it seems important to clarify the possible mechanisms linking obesity and skeletal muscle dysfunction regardless of age. Since steroids, namely, glucocorticoids (GCs) and sex steroids, have a major impact on the amount and function of both adipose tissue and skeletal muscles, and are involved in the pathogenesis of obesity, in this review, we will also discuss the role of steroids in the interaction of these two metabolically active tissues in the course of obesity.

Abstract
BACKGROUND Sarcopenia is thought to be related to an increased risk of non-alcoholic steatohepatitis and advanced liver fibrosis. Our cross-sectional single-center study was designed to analyze the prevalence of sarcopenia in patients with NAFLD and possible influencing factors. METHODS A survey on the presence of sarcopenia, fatigue, anxiety, and depression, along with a quality-of-life (QoL) assessment, was forwarded by email to 189 outpatients. Demographics, anthropometric and clinical data (laboratory test results and abdomen complete ultrasound protocol), performed within 2-4 weeks prior to the enrollment, were obtained. RESULTS Sarcopenia (defined as SARC-F score ≥ 4) was identified in 17 (15.7%) patients, all of them (100%) females, with median age (interquartile range) 56 (51-64) years. These patients had a poorer metabolic state (greater values of waist and hip circumferences, body mass index, and HOMA-IR) and significantly poorer QoL, specifically, regarding the physical component of health, compared with NAFLD patients without sarcopenia. Multivariate analysis showed that depression (OR = 1.25, 95% CI: 1.02-1.53, p = 0.035) and clinically meaningful fatigue (OR = 1.14, 95% CI: 1.04-1.26, p = 0.008) were the factors independently associated with sarcopenia in patients with NAFLD. CONCLUSION Sarcopenia is associated with depression and fatigue rather than with the severity of liver disease alone and may negatively affect QoL in patients with NAFLD.

Abstract
Background Left ventricular noncompaction (LVNC) cardiomyopathy is a disorder that can be complicated by heart failure, arrhythmias, thromboembolism, and sudden cardiac death. The aim of this study is to clarify the genetic landscape of LVNC in a large cohort of well-phenotyped Russian patients with LVNC, including 48 families (n=214). Methods All index patients underwent clinical examination and genetic analysis, as well as family members who agreed to participate in the clinical study and/or in the genetic testing. The genetic testing included next generation sequencing and genetic classification according to ACMG guidelines. Results A total of 55 alleles of 54 pathogenic and likely pathogenic variants in 24 genes were identified, with the largest number in the MYH7 and TTN genes. A significant proportion of variants -8 of 54 (14.8%) -have not been described earlier in other populations and may be specific to LVNC patients in Russia. In LVNC patients, the presence of each subsequent variant is associated with increased odds of having more severe LVNC subtypes than isolated LVNC with preserved ejection fraction. The corresponding odds ratio is 2.77 (1.37 -7.37; p <0.001) per variant after adjustment for sex, age, and family. Conclusion Overall, the genetic analysis of LVNC patients, accompanied by cardiomyopathy-related family history analysis, resulted in a high diagnostic yield of 89.6%. These results suggest that genetic screening should be applied to the diagnosis and prognosis of LVNC patients.

Non-alcoholic fatty liver disease (NAFLD) is reaching epidemic proportions worldwide. Moreover, the prevalence of this liver disease is expected to increase rapidly in the near future, aligning with the rise in obesity and the aging of the population. The pathogenesis of NAFLD is considered to be complex and to include the interaction between genetic, metabolic, inflammatory, and environmental factors. It is now well documented that NAFLD is linked to the other conditions common to insulin resistance, such as abnormal lipid levels, metabolic syndrome, and type 2 diabetes mellitus. Additionally, it is considered that the insulin resistance may be one of the main mechanisms determining the disturbances in both bone tissue metabolism and skeletal muscles quality and functions in patients with NAFLD. To date, the association between NAFLD and osteoporosis has been described in several studies, though it worth noting that most of them included postmenopausal women or elderly patients and originated from Asia. However, taking into account the health and economic burdens of NAFLD, and the increasing prevalence of obesity in children and adolescents worldwide, further investigation of the relationship between osteopenia, osteoporosis and sarcopenia in NAFLD, including in young and middle-aged patients, is of great importance. In addition, this will help to justify active screening and surveillance of osteopenia and osteoporosis in patients with NAFLD. In this review, we will discuss various pathophysiological mechanisms and possible biologically active molecules that may interplay between NAFLD and bone tissue metabolism.

Abstract
Aim To study the nosological structure of male mortality in 5-year age groups (15-85+) and the contribution of cardiac causes to all-cause mortality in 2020; to discuss the correctness of statistical recording of causes of cardiac death.Material and methods Data source: Center for Demographic Research of the Russian School of Economy http://demogr.nes.ru / index.php / ru / demogr_indicat / agreement. The selected indexes were all-cause death, causes of the class of circulatory diseases (CD) according to the International Classification of Diseases, Tenth Revision (ICD-10) (class IX, codes I00-I99), and cardiac causes of death (codes I00-I40, I70, I67.4, Q20-28) in 5-year age groups.Results Proportions of CD and cardiac causes in the male all-cause mortality were almost identical in the age groups younger than 30 years. Then the proportion of cardiac deaths remained almost unchanged (30-34 %) in contrast to the rapid growth of the CD proportion (to 51 % with a maximum at 75-79 years). Until the age of 45 years, more than 50% of cardiac deaths were caused by heart defects and cardiomyopathies and more than 25% by acute forms of ischemic heart disease (IHD); in older groups, their proportions decreased but the mortality increased. In the age groups younger than 50 years, the mortality from "Other forms of acute IHD" (ICD codes I20, I24.1-9 counted as one line) was higher than the mortality from myocardial infarction (MI); after 50 years, the MI mortality became higher. The combined proportion of two groups in the mortality from cardiac causes was maximal at the age of 20-24 years (31 %), then it decreased to a minimum of 9 % at the age of 85+. The mortality from and the proportions of chronic forms of IHD (more than 50% of which have no clear criteria for diagnosis and death), arterial hypertension, "Myocardial degeneration" (ICD code I51.5), and "Pulmonary heart and pulmonary circulation disorders" (ICD codes I26-I28) rapidly grow with increasing age. Existing approaches to recording the causes of death do not allow assessment of the contribution and mortality rates from a number of cardiac diseases.Conclusion Mortality reduction programs should provide more accurate recording of the causes of death and take into account age-related features of the nosological structure of cardiac mortality.

Abstract
STUDY PURPOSE To conduct a cross-sectional study on the structural and functional characteristics of various parts of skin microcirculation in working-age men with newly diagnosed hypertension (HTN). MATERIALS AND METHODS The study included 118 male participants (ages 30 to 60) who were not regularly taking any medicine, had no medical complaints, and subjectively considered themselves healthy at the time of study. All participants underwent a cross-sectional comprehensive medical examination. The following tests were performed: complete blood count, biochemical blood tests, video capillaroscopy (VCS), laser Doppler flowmetry (LDF) and photoplethysmography (PPG) on the left hand fingers, determination of flow-mediated vasodilation of the brachial artery, echocardiography, ultrasound of extracranial and femoral arteries, 24-h ambulatory blood pressure monitoring (ABPM). According to ABPM data, the participants were divided into two equal groups called a control group(CG) and a hypertension group(HG). There were 59 participants with normal BP in CG, and 59 participants with newly diagnosed HTN in HG. RESULTS Nailfold VCS of the ring finger revealed no significant differences between the groups at the level of exchange microvessels. According to LDF data, there was no decrease in tissue perfusion and signs of an increase in the activity of endothelial, neurogenic, and myogenic regulation of the tone of precapillary arterioles in the HTN group. According to PPG of the index finger, in contrast to CG, HTN participants had significantly higher values of the following parameters: normalized augmentation index (Alp75) - 3.8 % and - 5.25 % (p < 0.005), stiffness index (SI) - 7.6 m/s and 7.35 m/s (p < 0.05), reflection index (RI) - 36.5 % and 28.4 % (p < 0.005), respectively. DISCUSSION Working-age men in the early stage of HTN have neither capillary rarefaction nor an increase in the tone of skin precapillary arterioles. The largest contribution to peripheral vascular resistance in the onset of HTN is most likely made by large muscular arterioles, in which the neurogenic regulation of vascular tone predominates.

[PMID: 36883542 DOI: 10.33029/0042-8833-2023-92-1-74-84] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 12/01/2022] [Indexed: 03/09/2023]
Abstract
The low cardiovascular risk group according to SCORE in relation to the clinical and laboratory characteristics of patients is very heterogeneous, which leads to the presence of a residual risk of cardiovascular events. This category may include individuals with a family history of cardiovascular disease at a young age, with abdominal obesity (AO), endothelial dysfunction, and high levels of triglyceride-rich lipoproteins. In this regard, an active search is underway for new metabolic markers within the low cardiovascular risk group. The purpose of the study was to compare the nutrition, the adipose tissue distribution in low cardiovascular risk individuals, depending on the AO. Material and methods. The study included 86 healthy low risk (SCORE<1%) patients (mean age 42.6±2 years), who were divided into 2 groups: with AO [waist circumference (WC) >=94 cm in men and >=80 cm in women] - 44 patients (32% of men) and without AO - 42 patients (38% of men). The body composition was carried out using the bioimpedance analyzer. The distribution of ectopic fat deposits in the liver, pancreas and epicardial region was studied using ultrasound methods. A frequency questionnaire (Diet Risk Score) was used to assess nutrition. Results. In low risk patients with AO, signs of unhealthy diet are statistically significantly more common (in 52 in the main group vs 2% in the control group, p<0.01), ectopic deposition of adipose tissue in the liver (53 vs 9%, p<0.001), pancreas (56% in the main group, absent in the control group, p<0.001), epicardia l region (the epicardial fat thickness median is 4.24 mm in the main group vs 2.15 mm in the control group) compared with a control group. Conclusion. The low cardiovascular risk group is very heterogeneous. One of the markers of heterogeneity is central obesity - a marker of unhealthy diet, subclinical ectopic fat deposition and hypertriglyceridemia. Patients with AO of the low cardiovascular risk group require a more thorough examination with the obligatory determination of waist circumference, ultrasound assessment of the liver and pancreas parenchyma, and determination of the epicardial fat thickness. Using a short nutrition questionnaire allows you to quickly identify signs of unhealthy diet and discuss them with the patient.

Abstract
Early age-related changes in EEG time-frequency characteristics during the restful sleep of newborns of different gestational ages result in the development of conventional EEG signs of deep sleep already during the first postnatal week of their life. Allocating newborns to different groups based on their gestational age and duration of postnatal period allowed demonstrating substantial intergroup differences in brain activity during sleep and wakefulness, along with significant variability in the time-frequency characteristics of brain activity. The process of conventional deep sleep development in infants born prior to the week 35 of gestation is associated with an increase in the power of alpha activity in the sensorimotor cortex of the brain.

Abstract
Chronic liver disease (CLD), manifested as hepatic injury, is a major cause of global morbidity and mortality. CLD progresses to fibrosis, cirrhosis, and-ultimately-hepatocellular carcinoma (HCC) if left untreated. The different phenotypes of CLD based on their respective clinical features and causative agents include alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), metabolic-associated fatty liver disease (MAFLD), and drug-induced liver injury (DILI). The preferred treatment modality for CLD includes lifestyle modification and diet, along with limited pharmacological agents for symptomatic treatment. Moreover, oxidative stress (OS) is an important pathological mechanism underlying all CLD phenotypes; hence, the use of antioxidants to manage the disease is justified. Based on available clinical evidence, silymarin can be utilized as a hepatoprotective agent, given its potent antioxidant, antifibrotic, and anti-inflammatory properties. The role of silymarin in suppressing OS has been well established, and therefore silymarin is recommended for use in ALD and NAFLD in the guidelines approved by the Russian Medical Scientific Society of Therapists and the Gastroenterology Scientific Society of Russia. However, to discuss the positioning of the original silymarin in clinical guidelines and treatment protocols as a hepatoprotective agent for managing CLD concomitantly with other therapies, an expert panel of international and Russian medical professionals was convened on 11 November 2020. The panel reviewed approaches for the prevention and treatment of OS, existing guidelines for patient management for CLD, and available evidence on the effectiveness of silymarin in reducing OS, fibrosis, and hepatic inflammation and presented in the form of a narrative review. Key messagesAn expert panel of international and Russian medical professionals reviewed existing guidelines for ALD, NAFLD, MAFLD, and DILI to establish consensus recommendations that oxidative stress is the common pathophysiological mechanism underlying these conditions.The panel also discussed the positioning of original silymarin in clinical guidelines and treatment protocols as a hepatoprotective agent for managing CLD concomitantly with other therapies.The panel reviewed the effectiveness of 140 mg original silymarin three times a day in reducing oxidative stress in chronic liver diseases such as ALD, NAFLD, MAFLD, and DILI.

Abstract
To continue progress in the treatment of cardiovascular disease, there is a need to improve the overall understanding of the processes that contribute to the pathogenesis of cardiovascular disease (CVD). Exploring the role of gut microbiota in various heart diseases is a topic of great interest since it is not so easy to find such reliable connections despite the fact that microbiota undoubtedly affect all body systems. The present study was conducted to investigate the composition of gut microbiota in patients with atherosclerotic cardiovascular disease (ASCVD) and heart failure syndromes with reduced ejection fraction (HFrEF) and HF with preserved EF (HFpEF), and to compare these results with the microbiota of individuals without those diseases (control group). Fecal microbiota were evaluated by three methods: living organisms were determined using bacterial cultures, total DNA taxonomic composition was estimated by next generation sequencing (NGS) of 16S rRNA gene (V3-V4) and quantitative assessment of several taxa was performed using qPCR (quantitative polymerase chain reaction). Regarding the bacterial culture method, all disease groups demonstrated a decrease in abundance of Enterococcus faecium and Enterococcus faecalis in comparison to the control group. The HFrEF group was characterized by an increased abundance of Streptococcus sanguinus and Streptococcus parasanguinis. NGS analysis was conducted at the family level. No significant differences between patient's groups were observed in alpha-diversity indices (Shannon, Faith, Pielou, Chao1, Simpson, and Strong) with the exception of the Faith index for the HFrEF and control groups. Erysipelotrichaceae were significantly increased in all three groups; Streptococcaceae and Lactobacillaceae were significantly increased in ASCVD and HFrEF groups. These observations were indirectly confirmed with the culture method: two species of Streptococcus were significantly increased in the HFrEF group and Lactobacillus plantarum was significantly increased in the ASCVD group. The latter observation was also confirmed with qPCR of Lactobacillus sp. Acidaminococcaceae and Odoribacteraceae were significantly decreased in the ASCVD and HFrEF groups. Participants from the HFpEF group showed the least difference compared to the control group in all three study methods. The patterns found expand the knowledge base on possible correlations of gut microbiota with cardiovascular diseases. The similarities and differences in conclusions obtained by the three methods of this study demonstrate the need for a comprehensive approach to the analysis of microbiota.

Abstract
Rationale. Therapy with oral anticoagulants (OACs) in patients with atrial fibrillation (AF) is based on finding the optimal balance of efficacy and safety of these drugs. Data from observational studies are an additional source of information for the adverse events (AEs) of pharmacotherapy. Objective: To investigate pharmacotherapy AEs with OACs in the “ANTEY” prospective observational study in patients with non-valvular atrial fibrillation (AF). Material and Methods: A total of 201 people were enrolled (83 (41.3%) were women). The age of subjects was 71.1 ± 8.7 years (data presented as mean with standard deviation). The study protocol included two face-to-face visits (contacts V0 and V1) and one follow-up (FU) phone contact which were made with the patient at an interval of 6 months. At V0, all patients were recommended to take one of the non-vitamin K antagonist oral anticoagulants (NOACs); starting from V1, warfarin could have been prescribed or NOAC could have been changed. Information about AEs and OACsadministration was collected at V0, V1, and FU. Results. During 1 year of observation, 15 out of 201 patients refused to take OACs, and 186 initiated the recommended drug. Rivaroxaban was initiated in 93 patients, dabigatran in 46, apixaban in 40, and warfarin in 7 patients. There were 55 AEs, 25 of which were serious (SAEs), including 4 deaths. Of the 30 AEs, there were 18 bleedings: eight (8.6%) occurred with the administration of rivaroxaban; four (8.5%) with dabigatran, three (7.5%) with apixaban, and three (42.9%) with warfarin. Differences in the incidence of bleeding events between NOACs and warfarin are statistically significant (p = 0.025). Any AEs increased the chance of nonadherence to treatment nine-fold: OR = 9.2 (CI95%: 3.6−23.5), p < 0.0001. Conclusions. The most typical and common AEs in real-world clinical practice settings treatment with OACs were bleedings, the incidence of which was approximately 8% to 9% in the treatment with NOACs and was much higher with warfarin, bleedings in the treatment with OACs are statistically significantly associated with nonadherence to the use of these drugs in the future.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is often thought of as clinically asymptomatic. However, many NAFLD patients complain of fatigue and low mood, which may affect their quality of life (QoL). This may create a barrier to weight loss and hinder the achievement of NAFLD therapy goals. Our study aimed to evaluate the QoL in NAFLD patients vs. healthy volunteers, and to analyze likely influencing factors. From March 2021 through December 2021, we enrolled 140 consecutive adult subjects (100 NAFLD patients and 40 controls). Overall, 95 patients with NAFLD and 37 controls were included in the final analysis. Fatty liver was diagnosed based on ultrasonographic findings. We employed 36-Item Short Form Health Survey (SF-36) to evaluate QoL, Hospital Anxiety and Depression Scale (HADS) to identify anxiety and/or depression, and Fatigue Assessment Scale (FAS) to measure fatigue. NAFLD patients had significantly lower physical component summary scores, as well as significantly higher HADS-D scores, compared with the control group (Mann-Whitney U criterion = 1140.0, p = 0.001 and U = 1294.5, p = 0.022, respectively). Likewise, fatigue was more common in NAFLD patients (χ2 = 4.008, p = 0.045). Impaired QoL was significantly associated with fatigue (FAS score ≥ 22, p < 0.001) and depression (HADS-D ≥ 8, p < 0.001). In conclusion, NAFLD patients had significantly poorer QoL vs. controls, in particular with respect to the physical component of health. Impaired QoL may be associated with fatigue and depression, and together they may interfere with increased physical activity and lifestyle modifications in patients with NAFLD.

Abstract
One of the most common autosomal dominant disorders is familial hypercholesterolemia (FH), causing premature atherosclerotic cardiovascular diseases and a high risk of death due to lifelong exposure to elevated low-density lipoprotein cholesterol (LDL-C) levels. FH has a proven arsenal of treatments and the opportunity for genetic diagnosis. Despite this, FH remains largely underdiagnosed worldwide. Cascade screening is a cost-effective method for the identification of new patients with FH and the prevention of cardiovascular diseases. It is usually based only on clinical data. We describe a 48-year-old index patient with a very high LDL-C level without controlled guidelines-based medication, premature atherosclerosis, and a rare variant in the low-density lipoprotein receptor (LDLR) gene. Phenotypic cascade screening identified three additional FH relatives, namely the proband's daughter, and two young grandsons. The genetic screening made it possible to rule out FH in the proband's younger grandson. This clinical case demonstrates that genetic cascade screening is the most effective way of identifying new FH cases. We also first described in detail the phenotype of patients with a likely pathogenic variant LDLR-p.K223_D227dup.

Abstract
Cystic fibrosis, phenylketonuria, alpha-1 antitrypsin deficiency, and sensorineural hearing loss are among the most common autosomal recessive diseases, which require carrier screening. The evaluation of population allele frequencies (AF) of pathogenic variants in genes associated with these conditions and the choice of the best genotyping method are the necessary steps toward development and practical implementation of carrier-screening programs. We performed custom panel genotyping of 3821 unrelated participants from two Russian population representative samples and three patient groups using real-time polymerase chain reaction (PCR) and next generation sequencing (NGS). The custom panel included 115 known pathogenic variants in the CFTR, PAH, SERPINA1, and GJB2 genes. Overall, 38 variants were detected. The comparison of genotyping platforms revealed the following advantages of real-time PCR: relatively low cost, simple genotyping data analysis, and easier detection of large indels, while NGS showed better accuracy of variants identification and capability for detection of additional pathogenic variants in adjacent regions. A total of 23 variants had significant differences in estimated AF comparing with non-Finnish Europeans from gnomAD. This study provides new AF data for variants associated with the studied disorders and the comparison of genotyping methods for carrier screening.

Abstract
Aim To evaluate clinical practice of primary care physicians with respect of preventing behavioral risk factors in patients as well as objective and subjective factors that influence their motivation for taking preventive measures. Material and methods This study was a cross-sectional survey. The questionnaire was anonymous and included closed questions and multiple-choice questions. Based on the obtained results, prevalence of modifiable risk factors for chronic noninfectious diseases (CNID) was comprehensively evaluated in the survey population. Also, a special quantitative variable was introduced, the Index of Behavioral Risk Factors. that reflected the burden of risk factors. This composite index included the degree of risk factor in a specific respondent, for example, obesity degree, number of cigarettes smoked per day, severity of hypodynamia. Physicians' knowledge and beliefs about the effect of physical activity (PA) on certain diseases were evaluated. Result 623 physicians (mean age 40 years (31-52), 85.5 % women) participated in the survey. The respondents included general practitioners (7.5%), cardiologists (2.9 %), preventive care physicians (4.8 %), internists (25.4 %), and other specialists (59.4 %). 70.8 % of respondents never smoked, 17.5 % were current smokers. 38.5% (240) of the surveyed had a normal body weight index (BWI); 41.7 % (260) were overweight; 11.6 % (72) had degree 1 obesity; 3.7 % (23) had degree 2 obesity; and 0.8 % had degree 3 obesity. A very low PA level was noticed; most of the surveyed exercised not more than once a week (median, 1 (0-3) time). More than 90 % had behavioral risk factors, low PA and excessive body weight. The physicians with a higher index of behavioral risk factors 50% less frequently checked the body weight of patients (odds ratio (OR), 0.541; 95 % confidence interval (CI): 0.388-0.753, p<0.05); 33% less frequently asked whether the patient smoked (OR, 0.675; 95 % CI: 0.465-0.978, p=0.037); 50% less frequently asked the patients about his/her level of PA (OR, 0.482; 95 % CI: 0.343-0.678, p<0.001); and 60% less frequently recommended increasing the PA (OR, 0.408; 95 % CI: 0.292-0.570, p<0.001).Conclusion Most of the surveyed were aware of the benefits of PA for prevention and treatment of CNID, however, they related the mechanism of this effect only with weight loss. The most frequently mentioned barriers to behavioral risk counseling were uncertainty about whether such counseling was within the physician's professional competence, lack of time, lack of confidence in the provision of advice and the effectiveness of interventions, and lack of patients' compliance.
