In addition to systemic and respiratory symptoms, SARS-CoV-2 causes neurological disorders, as it is a neurotropic virus. Many scientists assume that SARS-CoV-2 can enter the nervous system through the functional receptor of angiotensin-converting enzyme 2, which is present in glial cells, neurons, skeletal muscles, and other organs. Neurological complications are manifested by damage to the central nervous system, peripheral nervous system, and cranial nerves, as well as by mental disorders. Mental illnesses develop due to neuroinflammation and neuronal death after brain infection with SARS-CoV-2.The article describes a clinical case of a 63-year-old man with the co-occurring novel coronavirus infection and obvious mental disorder who has never had any mental illnesses before. The given clinical example demonstrates the importance of studying the cause-and-effect relationship between COVID-19 and mental illness. In the mediumand long-term perspective, COVID-19 is expected to result in mental health disorders during COVID-19 recovery. Besides, an increase in the number of patients with mental disorders who were mentally healthy before COVID-19 infection is also expected.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":" 84","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131923467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though numerous studies convincingly proved that deterioration of the left ventricular (LV) filling pressure often precedes impairment of its systolic function and a number of factors affect (especially at the onset) mainly the diastolic function without changing the conditions of blood ejection, modern classifications and approaches to CHF treatment are primarily based on the results of LV ejection fraction (EF) assessment.In recent years, diastolic heart failure (DHF) has been often overlooked and replaced by the ambiguous term “CHF with preserved EF”. However, sometimes authors use the term DHF extensively, since CHF based on myocardial insufficiency develops only via two mechanisms (systolic and / or diastolic dysfunction), and excluding one of the mechanisms allows to identify the underlying one. The term DHF can be used in clinical practice and cannot be replaced by the diagnosis of CHF with preserved EF. CHF with preserved EF is a broader concept which includes a full spectrum of cardiovascular diseases, complicated by the development of CHF without depression of the global LV contractility and requiring differentiated approaches to therapy. In addition, the results of repeated studies on LVEF in many patients may require reclassification of this CHF phenotype, which is established following the analysis of the baseline value of global LV contractility. We join M.R. Zile in the appeal to stop discriminating against the term “DHF” and present the boundaries of its correct application.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"381 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131720541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Available data suggest that bacterial infection in patients with COVID-19 is rare and occurs in less than 10% of cases. At the same time, data of individual studies and systematic reviews indicate that more than 70% of patients with COVID-19 receive mainly empirical antimicrobial therapy with broad-spectrum antibiotics often before the diagnosis of COVID-19 has been verified. Therefore, this widespread empirical use of antibiotics is not supported by data on the need for their use.The article discusses the literature data on the significance of commonly accepted methods for diagnosing bacterial infection, with an emphasis on laboratory presence / absence tests. In everyday practice, the likelihood of bacterial coinfection in patients with COVID-19 is assessed by clinical presentation of the disease and the results of standard laboratory tests and imaging methods. However, when viral respiratory infection develops, this approach does not always allow to diagnose bacterial coinfection with sufficient significance. This issue may be handled by available modern test systems, the use of a combination of signs or additional laboratory criteria (for example, procalcitonin), and the analysis of the overall clinical presentation by the doctor using knowledge about patient risk groups.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121051375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To analyze the structural, magnetic, and cytotoxic features of magnetite nanoparticles (MNPs) prepared by the exploding wire method and stored in a dark place at ambient temperature (65 ± 15% humidity, air pressure 760± 20 mm Hg., temperature 22 ± 4 °C) for 10 years.Materials and methods. The properties of MNPs were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SAED), and vibrating-sample magnetometer (VSM). Viability of human blood mononuclear leukocytes was determined using 0.4% trypan blue staining after 24-hour culture with the nanopowder.Results. The calculated size of the particles remained almost unchanged after 10 years of storage. The XRD and SAED patterns showed that crystallinity was preserved for 10 years. The diameter of the crystalline component of MNPs (DXRD) was close to the particle size determined by TEM. It confirms high crystallinity of the tested nanoparticles. Saturation magnetization (MS) of the MNP powder after 10 years of storage was unexpectedly higher than that of the as-prepared MNP powder. Reduced remanent magnetization (MR / MS) was equal for both samples within the margin of error. No cytotoxic effect of MNPs in vitro was detected in the long-term study.Conclusion. No dramatic changes in the structural, magnetic, and cytotoxic features of MNPs were noted after 10 years of storage. It indicated 10-year stability of MNP powder that may be a useful feature for environment safety and biomedical applications.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128169589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the association between the functional potency and degree of maturity of B lymphocytes and PD-L1 expression in breast cancer patients.Materials and methods. The study included 37 patients with the morphologically verified diagnosis of invasive breast cancer of no special type (IBC NST). The PD-L1 status was determined immunohistochemically using the Ventana SP142 assay (Roche, USA). Using the multiplex flow cytometry-based assay and high-throughput sequencing of the tumor microenvironment, subpopulations of B lymphocytes and their CD27 and PD1 expression profiles were determined, taking into account the PD-L1 status.Results. In the tumor microenvironment, regardless of the PD-L1 status, expression signatures of five lymphocyte subpopulations were determined. However, in PD-L1-positive patients, the levels of B lymphocytes and immunoglobulin class-switched B lymphocytes were higher compared with PD-L1-negative patients. Evaluation of the number of different B lymphocyte subpopulations by flow cytometry showed that PD-1-positive B lymphocytes predominated in the tumor microenvironment in PD-L1-positive patients, regardless of the degree of lymphocyte maturity.Conclusion. The results of the study showed predominance of mature committed B lymphocytes and memory B lymphocytes capable of synthesizing immunoglobulins of different classes and Th2 cytokines involved in type 2 immune response in PD-L-positive tumor microenvironment. It suggests that immunotherapy with PD-L1 inhibitors is highly likely to activate cells with protumor potential and can ultimately contribute to breast cancer progression.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116760942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the possibility of using a radiopharmaceutical based on aluminum oxide labeled with 99mТс ([99mТс]-Al2O3) for the diagnosis of sentinel lymph nodes (SLN) in tumors of the larynx and laryngopharynx in comparison with a phytate colloid ([99mTc]-phytate colloid).Materials and methods. The study included patients with cancer of the larynx and laryngopharynx (T2–4N0M0) (n = 54). In the prospective group (n = 30), [99mТс]-Al2O3 was used as a radiopharmaceutical, in the retrospective group (n = 24), [99mТс]-phytate colloid was used. All radiopharmaceuticals were introduced endoscopically into the submucosal space along the periphery of the tumor. After 18 hours, single-photon emission computed tomography (SPECT) and intraoperative SLN detection were performed.Results. In the retrospective group, SLNs were detected in 20 out of 24 patients. A total of 32 lymph nodes were identified in the retrospective group. The median number of detected lymph nodes in one patient was 1.3 [0–3], the intensity of the radiopharmaceutical uptake on scintigrams was 2.2 [0.7–8.1], intraoperatively – 4 [1.6–9.0]. In the prospective group, [99mTc]-Al2O3 uptake in the lymph nodes of the neck was determined in 27 patients (90%); in3 patients, SLNs were not visualized. A total of 57 lymph nodes were identified (in 27 patients). The median number of visualized SLNs was 1.5 [0–5], the intensity of [99mТс]-Al2O3 uptake according to SPECT and intraoperative detection was 4.8 [0.7–19.4] and 6 [1.1–22.0], respectively.Conclusion. The most significant advantage of using [99mТс]-Al2O3 as a radiopharmaceutical is its high uptake in SLNs, which leads to an increase in the sensitivity of the method as a whole up to 90 versus 83% when using [99mTc]-phytate colloid.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126563961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study pathohistological changes in the myocardium of rats with chronic alcohol intoxication (CAI) after treatment with a new glutamic acid derivative glufimet (compound RSPU-238) and a new gamma-aminobutyric acid (GABA) derivative (compound RSPU-260).Materials and methods. Experiments were performed on female Wistar rats aged 10 months. The rats were divided into the following groups: group 1 – intact females; group 2 – a control group which included animals after CAI simulated by replacing drinking water with 10% ethanol solution for 24 weeks; groups 3 and 4 – experimental groups, in which females were intraperitoneally administered with glufimet at a dose of 28.7 mg / kg and RSPU260 at a dose of 25 mg / kg once a day for 14 days after cessation of alcohol solution consumption; group 5 – a group of animals receiving a reference listed drug mildronate at a dose of 50 mg / kg according to a regimen similar to that of the studied compounds. Changes in microstructural and morphometric parameters of the left ventricular myocardium were assessed using light microscopy.Results. In animals after CAI, the cardiomyocyte volume fraction decreased, while the interstitial and vascular volume fractions increased. Degeneration of cardiomyocytes, such as their wave-like deformation, loss of transverse striation, foci of plasmolysis, and fragmentation of muscle fibers were revealed. In rats treated with glufimet, the structural changes in cardiomyocytes were minimal. Lower vascular plethora was observed; blood vessels were characterized by single stasis and sludge. The cardiomyocyte volume fraction was 9.7% greater than in control animals, while the interstitial and vascular volume fractions were 66.0 and 70.0% smaller, respectively. The animals treated with the RSPU-260 compound had no significant degenerative changes in cardiomyocytes and small vessels similar to the experimental animals injected with glufimet. Mildronate had a less pronounced cardioprotective effect.Conclusion. Administration of new GABA and glutamic acid derivatives to animals with simulated chronic alcohol intoxication leads to improvement of the microstructure in cardiomyocytes compared with control rats. This indicates pronounced cardioprotective effects of the studied neuroactive amino acid derivatives.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127752453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The metagenomic approach allowed to identify microorganisms at molecular level both in healthy lung tissues and in malignant ones.The next stage of research is investigation of the effects of microbiota on homeostasis and immune stability in the lungs. The analysis of lung microbiota based on 16S rRNA gene sequencing revealed that microbiota of healthy lungs is mainly presented by bacteria of the phyla Bacteroidetes, Firmicutes, Proteobacteria, and Fusobacteria. In lung cancer, an increase in the number of bacteria of some certain genera and a decrease in microbiota diversity on the whole are noted. Dysbiosis facilitates reproduction of pathogens and development of lung diseases. It was detected that under normal conditions, microbiota maintains resistance of the lungs to bacterial colonization and plays a crucial role in providing a balanced immune response in this organ.","PeriodicalId":256912,"journal":{"name":"Bulletin of Siberian Medicine","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121771373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A single-center, one-stage, cross-sectional study included 235 patients with type 1 and type 2 diabetes mellitus and 82 persons of the control group (the total of 317 patients). Further, the obtained data were processed using the MATLAB software to develop an ANN with a training (80%) and test (20%) set. The ANN model was trained by optimizing the relationship between a set of input data (a number of clinical and laboratory parameters: gender, age, body mass index, duration of diabetes mellitus, etc.) and a set of corresponding output data (variables reflecting the state of bone metabolism: bone mineral density, markers of bone remodeling).Results. The ANN-based algorithm predicted estimated values of bone metabolism parameters in the examined individuals by generating output data using deep learning.

We examined 63 patients with schizophrenia and MetS (25 women, 38 men), aged 30 [33;52], and 50 mentally healthy individuals with MetS (28 women, 22 men) aged 57 [49; 60]. The main criterion for inclusion in the study was the presence of a verified MetS according to the criteria of the International Diabetes Federation. Anthropometric examination was performed according to the method of V.V. Bunak (1941) with the underlying calculation of integral indices. The determination of the fat component included: measuring waist circumference; non-invasive bioimpedancemetry – body weight, BMI, total and visceral fat content; determination of the total fat fold (electronic caliper). In the blood serum, the concentration of glucose, total cholesterol, HDL, TG was determined using standard commercial kits, the calculation of LDL and the Atherogenic Index.Results. Differences in the prevalence of the constitutional-morphological type and the type of somatic sexual differentiation were not established in the groups. The level of visceral fat and BMI were higher in mentally healthy individuals with MetS than in schizophrenic patients with MetS (p = 0.005 and p = 0.0001, respectively). Patients with schizophrenia and MetS had low serum glucose levels compared with individuals without mental disorders (p = 0.0001). An increase in the level of TG and the Atherogenic Index was found in patients with schizophrenia with MetS (p = 0.026 and p = 0.03, respectively), and the level of HDL was reduced (p = 0.022).Conclusion. The constitutional and morphological basis of MetS in patients with schizophrenia and persons without mental disorders is the same, however, changes in the fat constitution were determined for mentally healthy individuals.
