Mechanisms of action of fungal polysaccharides and their therapeutic effect.

The purpose of this article is to discuss the relationship between the therapeutic bioactivity of basidial fungal polysaccharides (BFPs) BFPs and their structural characteristics and conformational features, as well as to characterize the mechanisms of action of BFPs in diseases of various origins. The review was conducted using the PubMed (Medline), Scopus, Web of Science and the Russian Science Citation Index databases. 8645 records were identified, of which 5250 were studies (86 were randomized controlled trials). The period covered is from 1960 to the present. The most significant studies conducted mainly in Southeast Asian countries were selected for the review. Based on clinical studies, as well as the results obtained on in vivo, in vitro and ex vivo models, it has been proven that BFPs have diverse and highly effective biological activity in the human body in various diseases. The production of BFPs-based vaccines is an innovative strategy from a clinical and biochemical point of view, since as potential immunoprotective and low-toxic biopolymers they have innate immune receptors in the body. Promising results have been obtained in the development of antidiabetic drugs, probiotic, renoprotective and neurodegenerative dietary supplements. The biological activity, mechanism of action and specific therapeutic effect of BFPs largely depend on their structural and physicochemical characteristics. BFPs as multifunctional macromolecular complexes with low toxicity and high safety are ideal as new powerful pharmaceuticals for the treatment and prevention of many diseases.

The role of Helicobacter pylori in the development of inflammatory eyelid diseases

Background. Blepharitis is one of the most common eye diseases: it accounts for 23.3 % of the total number of patients with inflammatory eye diseases worldwide. 40.2 % of these patients seek outpatient care. The incidence of blepharitis is 1.5–2 times higher in women than in men. The leading factors in the development of blepharitis are both general (gastrointestinal tract diseases, diabetes mellitus, hypertension, systemic use of corticosteroids, etc.) and local (atopic and seborrheic dermatitis or rosacea). The main causative agents of this disease are Staphylococcus spp. (S. aureus, S. epidermidis). As a rule, the disease manifests itself in patients aged 30–50 years, while in women aged 40 to 45 years, 80 % of blepharitis are of staphylococcal origin. Currently, there are reports in the literature about apotential link between Helicobacter pylori infection and the development of chronic blepharitis, but the data are very contradictory.The aim of the study. To analyze the features of the relationship between Helicobacter pylori and inflammatory eyelid diseases.Materials and methods. We conducted a search and analysis of literary sources in the Web of Science, PubMed and Google Scholar databases, as well as in the Russian Science Citation Index database for the period from 2000 to 2022.Conclusion. The review analyzes and summarizes the pathogenic mechanisms of the relationship between chronic blepharitis and Helicobacter pylori. We carried out an analysis of numerous studies, which give grounds to assume a possible role of Helicobacter pylori infection in the development and course of inflammatory eyelid diseases (blepharitis). The main pathogenic aspects in these studies are: chronic inflammation of the eyelids and gastrointestinal tract (antigenic mimicry); excretion of toxic substances from the oral cavity (ammonia, hydrogen nitrite, hydrogen cyanide and other substances causing indirect inflammation of the conjunctiva and eyelid cartilage); the presence of Helicobacter pylori in tears.

Open Access Models of Russian Academic Journals

Open access (OA) to publications has been a global trend in publishing academic journals for a long time. The number of OA journals, including Russian ones, is growing steadily. The purpose of this study was to determine the main trends in the implementation of open access publishing models in Russian research journals. The article presents the results of a study of 396 journals included in the Russian Science Citation Index database: title of a journal; website address; international classification code (OECD group); quartile; Science Index indicator; open access model; license type; section of a journal’s website that contains information about the absence or presence and amount of an article processing charge (APC). It is concluded that the majority of journals implement Bronze OA which, firstly, does not comply with the key principles of open access, because it does not use open licenses, and, secondly, does not provide any guarantees that open access will continue to be open. The lack of accessible and transparent information about the conditions for further use of publications can create serious legal issues for the licensee. In turn, it will most likely be a problem for authors to calculate the amount of publication fee.

Open access and open licensing by Russian journals

In the circumstances of transforming institution of intellectual property, the journals have to find balance between the open science initiatives and legal regulations. The purpose of the study is to define whether Russian academic journals conform to open science initiatives and, in particular, to the open access principles and open licensing terms. The author discusses the findings of the study encompassing 450 journals in the Russian Science Citation Index database (as of December 1, 2022) using the following criteria: journal allocation site, archive depth, access principle, license terms and the website section on licensing terms. Based on the obtained data systematization and analysis, the trends for Russian academic journals are formulated: in general, they are ready for introducing open access principles. By choosing open licensing, most of the Russian academic journals are ready to offer maximum freedom in using their publications. The author developed several recommendations for the journals as the sites of scientific data exchange, and for the researchers as the users, generators and disseminators of these data.

Mitral allografts in tricuspid valve position in modern surgery of acquired heart defects: a systematic review

Introduction: In severe recurrent infectious lesions in the right heart, one of the alternative options for bioprosthetics is to implant mitral allografts (donor heart valves) in the tricuspid valve position. Allografts offer numerous benefits, including a configuration that closely resembles a native valve, adaptability to high systemic pressure, absence of foreign elements that can could act as entry points for infections, and antibacterial treatment without lifelong anticoagulant therapy.Objective: To study the feasibility of using a mitral allograft in the tricuspid position based on the analysis of literature data and our own experience.Methods: Searches were conducted in Medline (PubMed), Google Scholar, and Russian Science Citation Index databases using search queries, keywords, and logical operators. The last session was conducted on December 21, 2022. In the initial selection of aforementioned search queries, a total of 4,446 results were obtained (Google Scholar — 3,080, Medline — 1,050, Russian Science Citation Index — 316). After analyzing titles and abstracts, 4,390 studies were excluded due to the insufficient data. Of the remaining studies, 25 scientific papers were excluded due to their duplication. The final group included 31 studies.Results: Based on a systematic literature review, the article presents aspects of the explantation, preparation, and implantation of the mitral allograft in the tricuspid position at the present stage of biotechnology development. The article highlights the main complications, rare clinical observations, and immediate and long-term postoperative results of mitral allograft implantation in the tricuspid position.Conclusion: This technique presents an interesting solution for patients with severe structural changes in the tricuspid valve, but further research is necessary at this stage of biotechnology development.

Medical and biological support of elite sports: recovery and rehabilitation measures

Purpose of the study: to analyze the content and systematize the scientific and methodological materials on research in recovery and rehabilitation in the medical and biological support (MBS) of elite sports. Materials and methods. The research included content analysis of literature sources. Articles included in the PubMed, Scopus, Google Scholar, and Russian Science Citation Index databases were examined. Total of 97 articles were analyzed, and 44 were selected. Results and discussion. Recovery and rehabilitation in sport includes a set of medical, professional, psychological, and pedagogical measures aimed at the restoration or compensation of impaired body functions and sports performance. Among the existing set of means and methods of rehabilitation used in medical practice in the medical and biological support of sports at the present time, the methods that allow quickly eliminating signs and consequences of physical and psychoemotional tension (stress) observed during sports activities, and restoring psychofunctional state through direct impact on regulatory systems (nervous, humoral, and hormonal systems) of the human body are of particular interest. There are active studies on the use of transcranial methods of electrical and magnetic stimulation, as well as biofeedback, which allow the development of the ability to control one’s psychophysiological functions. The analysis of recovery and rehabilitation methods of local impact on the musculoskeletal system has shown that there are very few developments and studies associated with the use of modern physiotherapy and mechanotherapy equipment adapted for application in sports. The use of natural healing resources for recovery and rehabilitation of the human body is sufficiently studied and substantiated by research conducted over the years. However, there are few studies on the influence of natural healing factors on the functional state of the body and the performance ability of athletes. Conclusion. The study has shown various recovery and rehabilitation technologies with application of total and local impact methods. However, there are gaps regarding a lack of studies on the scientific justification of applying natural healing resources and modern mechanotherapy measures with great possibilities for recovery and rehabilitation of the human body’s functional systems, adapted for use in sports, as well as the absence of a formed system for recovery and rehabilitation of athletes in conditions of training in middle altitude.

Three personality facets can relate to increased academic output

We studied how personality traits relate to academic output indicators. Three-hundred Russian academic authors agreed to participate in the study. They completed the Big Five Inventory-2 online; we gathered their h-index, publication counts, and citation counts using the core Russian Science Citation Index database. Three personality facets-Creative Imagination, Productiveness, and Emotional Volatility- showed persistent incremental effects across the academic indicators. Moreover, Emotional Volatility interacted with either Creative Imagination or Productiveness meaning that the authors showed greater academic performance when their creativity or persistence in pursuing goals were accompanied by larger mood swings. Based on these findings and extant literature, we propose an emotional volatility hypothesis, which complements tenets of the normative theory of increased academic output.

К ПЯТИЛЕТНЕМУ ЮБИЛЕЮ НАУЧНОГО РЕЦЕНЗИРУЕМОГО ЖУРНАЛА "ВОДНЫЕ БИОРЕСУРСЫ И СРЕДА ОБИТАНИЯ"

The scientific peer-reviewed journal “Aquatic Bioresources & Environtment” has been published since 2018 and functions as a discussion platform for researchers and practitioners of the vast fishery region (mainly the Southern Russia). In July 2023, the journal celebrated its fifth anniversary. The aim of this article is to review the notable milestones of the formation of the journal as a scientific publication from its first issue up to the present moment. Currently, the journal is included in the List of peer-reviewed scientific publications, in which the main scientific results of dissertations for the degree of Candidate of Science and for the degree of Doctor of Science should be published (List of the Higher Attestation Commission), and is abstracted in the International Information System for Aquatic Sciences and Fisheries Abstracts (ASFA) and the Scientific Electronic Library e-library.ru (eLIBRARY), as well as indexed in the Russian Science Citation Index (RSCI). Articles in the journal are assigned with Digital Object Identifiers (DOI), which are registered by the international agency Crossref; they are posted on the journal's website and added to RSCI and other databases.

The Russian Journal of Oncology and Russian Science Citation Index

The Russian Journal of Oncology is indexed in many databases, including the Russian Science Citation Index (RSCI). The journal is included in the List of peer-reviewed scientific publications for publishing the main scientific results of Ph.D. theses recommended by the Higher Attestation Commission (hereinafter referred to as the HAC List), which is characterized by structuring by scientific branches, scientific fields, and scientific specialties. Since 2021, the journal citation in the RSCI database has been equated in its value to indexing in the Web of Science Core Collection and/or Scopus, which is a criterion for the quality of a publication and a guideline in choosing a scientific journal by the authors for publishing the results of thesis research. Thus, when preparing a thesis paper, the list of publications can include those works of the applicant that are published in scientific journals presented in the HAC List in the relevant specialty, or in scientific journals indexed in RSCI, Web of Science and/or Scopus, regardless of the scientific specialty and relevant fields of science these journals are included in the HAC List, and whether they are included at all.
 Taking into account the changes that have taken place, the editors and the publisher continue to publish articles on molecular biology (1.5.3), genetics (1.5.7), oncology, radiation therapy (3.1.6), radiation diagnostics (3.1.25), surgery (3.1.9), neurosurgery (3.1.10), pediatric surgery (3.1.11), cardiovascular surgery (3.1.15), plastic surgery (3.1.16), maxillofacial surgery (3.1.2), pathological anatomy (3.3.2), and clinical laboratory diagnostics (3.3.8) in the Russian Journal of Oncology.

Intraoperative methods for assessing blood loss: A review

Massive blood loss that develops during surgery is a common cause of life-threatening conditions and deaths in patients of any age.
 This study aimed to analyze domestic and foreign publications that present methods for determining the volume of intraoperative blood loss.
 The literature sources were searched in PubMed, Scopus, Web of Science, MEDLINE, eLibrary, and Russian Science Citation Index databases. The search was conducted in Russian and English using the following keywords: intraoperative blood loss, severity of blood loss, methods for assessing blood loss, direct methods, and indirect methods. The literature review included five articles from PubMed, nine from Scopus, six from Web of Science, two from MEDLINE, six from eLibrary, and four from Russian Science Citation Index.
 Massive blood loss is understood as a one-time loss according to some authors of 30% and according to others of 50% of the volume of the circulating blood or blood loss equal in volume to 23 mL/kg/min. Risk factors for the development of intraoperative complications such as massive blood loss are, in addition to surgical interventions, the features of surgical intervention, i.e., size of the incision, surgical duration, and anesthesia, which can increase blood loss. The intensity and degree of blood loss are very important in determining the indications for transfusion of blood components, replenishing the volume of circulating blood, and determining indications for intraoperative hemostasis, both medical and surgical. In neonates and young children, the risk of dangerous intraoperative blood loss is associated with anatomical and physiological features, i.e., a small volume of circulating blood and insufficiently mature compensatory mechanisms. In older children, a high risk of massive blood loss is associated with comorbidities, features of hemostasis, and use of drugs that slow down the blood coagulation process.
 To date, several methods are available for assessing intraoperative blood loss, but only a few are used in routine clinical practice. Each method has advantages and disadvantages. One of the main disadvantages is the complexity of the mechanisms for assessing blood loss, for example, weighing surgical materials or the patient before and after surgery, determining hemoglobin in the liquid after soaking the used surgical materials, and calculating indices using formulas. Most often, the assessment of blood loss is conducted according to the clinical picture (pallor of the skin and mucous membranes, weak pulse, lowering blood pressure, etc.).
 The results of the literature analysis showed insufficient research on determining the volume of intraoperative blood loss in pediatric practice, as evidenced by the small number of published scientific papers and the complete absence of randomized trials. Thus, further study of this problem is necessary.

Comparative analysis of bibliometric indicators of Russian journals in agroengineering

The results of the bibliometric analysis of scientometric indicators of scientific journals in the sphere of agricultural mechanization and electrification are presented. The publications were selected based on SRSTI (State Rubricator of Sci-tech Information, GRNTI). All national journals in the area were analyzed. The selected bibliometric indicators provide for the multirater assessment of the journals. These are: citation five-year impact factor, loadings, and self-citation coefficient. Russian Science Citation Index (RSCI) Database served as the source for the data on every journal. Finally, five most significant publications were chosen, with three of them already included in the RSCI Database, and the remaining two – being recommended for inclusion. The completed comparative analysis permits to identify the most demanded journals for each indicator. The Scientific Journal of KubSAU is the most cited one, also leading in the number of loadings. The Agricultural Machinery and Technologies Journal demonstrates the highest impact factor. The Tractors and Agricultural Machinery Journal shows the lowest self-citation coefficient. The factors to increase the use of scientific serials are discussed. The obtained results may be used to increase authority and citation of publications in agroengineering, and to support their acquisition to the sci-tech library collections.

Unintentional subarachnoid administration of tranexamic acid during spinal anesthesia

An accidental intrathecal tranexamic acid injection is a rare but extremely unpleasant case, which can lead to severe complications, including death. This review aimed to describe the clinical, pathophysiological changes and outcomes occurring in patients with unintentional tranexamic acid subarachnoid injection during spinal anesthesia. The review includes studies published in PubMed, The Cochrane Library, Google Scholar, and the Russian Science Citation Index databases. There were 31 reports (27 literature reports and 4 own observations) of unintended tranexamic acid administration during spinal anesthesia, including 12 cases in traumatology and orthopedics, 11 cases in cesarean section, and 8 cases in urology and general surgery. Typical signs and symptoms reported by the authors include severe pain in the lower back, buttocks, and lower extremities, seizure syndrome, marked tachycardia and arterial hypertension, and ventricular arrhythmias. Ten (32.1%) patients recovered without any consequences and six (19.4%) patients required long-term rehabilitation after hospital discharge due to severe neurological deficits or cognitive impairment. Of 11 females, 9 died during cesarean section and 4 of 12 patients died in traumatology and orthopedics. Overall, 15 (48.4%) patients had a fatal outcome. An unintentional subarachnoid tranexamic acid injection is a catastrophic event with extremely high patient risk and is accompanied by high mortality, especially in obstetric practice. Intensive care should include intravenous propofol or sevoflurane inhalation in the case of unintentional intrathecal tranexamic acid injection, and cerebrospinal fluid lavage is promising. Developing a formalized protocol for intrathecal administration of local anesthetic solutions is advisable to avoid errors associated with accidental drug administration not intended for spinal anesthesia.

Adverse events in health and safety management in healthcare: meaning and management tools

Highlights. It is necessary to manage adverse events in order to maintain health and safety of patients and medical workers in the process of healthcare. One of the tools that can improve the system of managing such events is the Poka-Yoke technique.Aim. To theoretically justify and analyze the possibility of using lean manufacturing tools in the management of adverse events to ensure the quality and safety of healthcare.Methods. The analysis of domestic and foreign literature, regulatory and legal documentation for the period from 2015 to 2021 was carried out. The following keywords were used as search terms: “adverse events”, “medical error”, “risk management in healthcare organization”, “Poka-Yoke technology”, “adverse events management system”. The Russian Science Citation Index database, “Garant” reference system and Google Scholar search engine were used to find full text publications. The analysis of public reports of government officials on the issues of improving the safety of healthcare was carried out. The methods of system and logical analysis were used for the analysis. The article presents the experience of developing an adverse events management system at the Federal State Budgetary Institution “Research Institute for Complex Issues of Cardiovascular Diseases” (Kemerovo, Russia).Results. The analysis revealed a variety of approaches to management of adverse events. The authors believe that the “Poka-yoke” method, described in the set of national standards and technical specifications maintained by the Russian Federation “GOST R 56407-2015 Lean manufacturing. Basic methods and tools”, can be implemented in the process of managing adverse events. The main advantage of Poka-yoke method is the fact that it is prevention-based; thus, it is possible to introduce the concept of zero defects in healthcare process. The experience of the Federal State Budgetary Institution “Research Institute for Complex Issues of Cardiovascular Diseases” confirms the expediency of using this technique for the development of the adverse events management system.Conclusion. Implementation of the Poka-Yoke technique leads to the improvement in the adverse events management system.

Introduction.The review is aimed at analyzing the worldwide experience in the use of the oral mucosa in ureteroplasty due to benign ureteral strictures.Objective.To study the features of the use of the oral mucosa in ureteral reconstruction based on a review of the worldwide literature.Materials and methods.The review was conducted using the PubMed, EMBASE, and the Russian Science Citation Index database. In the first stage, 1013 sources were found, of which 38 articles were selected for inclusion in the review. Of these, 13 studies used an open approach, 15 — robotic, 6 — laparoscopic, 3 — laparoscopic and robotic, 1 — open and laparoscopic. A buccal graft was used in 29 studies and a lingual graft was used in 9 studies.Results.In total, oral mucosal ureteroplasty was performed 308 times in 306 patients: open technique — 64 times, robotic — 145 times, laparoscopic — 99 times. A buccal graft was used in 67.9% (209/308) of the cases, a lingual graft was used in 32.1% (99/308). Postoperative complications were observed in 15.9% (49/308) of the cases: 12.2% after the open technique, 10.4% after the robotic technique and 20.2% after the laparoscopic technique. With a postoperative follow-up period of 1 to 85 months (average 15.3 months), treatment success was achieved in 92.5% (285/308) of the cases: 93.8% for open technique, 88.2% for robotic, 98.0% for laparoscopic.Conclusion.The use of the oral mucosa for ureteroplasty due to benign ureteral stricture allows high rates of efficiency and safety. The results of ureteroplasty do not depend on the choice of surgical approach, type of graft and graft transplantation technique.

Epidemiology and Infectious Diseases journal and its indexation in Russian Science Citation Index

The Epidemiology and Infectious Diseases journal is indexed in a variety of scholarly databases, including the Russian Science Citation Index (RSCI), and is also included in the LIST of peer-reviewed scientific journal in which the main results of dissertations should be published for the degree of Candidate of Science, for the degree of Doctor of Science recommended by Higher Attestation Commission of Russian Federation (the List of VAK). At the same time, the List of VAK is structured by branches of science, scientific areas and scientific specialties, while RSCI is not. Since 2021, the indexing of a journal in the RSCI database has been equated in its value to indexing in the Web of Science Core Collection and/or in Scopus, as a criterion for the quality of a journals to be choose by an author for publishing the results of dissertation research. Thus, when preparing a dissertation work in Russian Federation, the list of publications can include those of the applicants works that are published in scientific journals from the List of VAK in the relevant specialty, or in scientific journals indexed in RSCI, Web of Science and/or in Scopus (regardless of whether in what scientific specialty and relevant areas of science these journals are included in the List of VAK, and whether they are included at all). Taking this into account, the editors and the publisher continue to publish articles on epidemiology (VAK spatiality code 3.2.2), infectious diseases (3.1.22), virology (1.5.10), medical microbiology (1.5.11) and parasitology (1.5.17) in the Epidemiology and Infectious Diseases journal.

Health risks of air pollution with fine particulate matter

The review presents up-to-date information on the health effects of ambient fine particulate matter, obtained in large cohort epidemiological studies, as well as in meta-analysis of pooled data. In addition, it summarizes the current data on the potential pathological mechanisms and existing monitoring systems. The literature search used the Scopus, PubMed, Russian Science Citation Index databases for 19902020. The results of epidemiological studies carried out in different countries indicate that fine particles in ambient air pose a serious threat to health. Scientific publications assessing the health impact of particulate matter show a wide range of adverse effects from the increasing incidence of upper and lower respiratory tract diseases, including exacerbations of bronchial asthma, pneumonia, chronic obstructive pulmonary disease, to a high incidence of myocardial infarction, strokes, diabetes mellitus type 2, as well as an increase in overall mortality from natural causes, mainly mortality from respiratory diseases, cardiovascular and cerebrovascular diseases, lung cancer. The effects of short-term exposures are described in more detail, while the effects of long-term exposure to fine particles are not well understood. Potential mechanisms of the harmful effects of fine particulate matter include oxidative stress, inflammatory reactions, disorders of autonomic regulation and heart rhythm, fine particles translocation through the alveolar barrier into the vascular bed with endothelial damage and thrombus formation, and genotoxicity. Ambient fine particulate matter is a manageable risk factor, and reductions in air pollution will have a significant impact on public health outcomes.

Predictive biomarkers of inhibitors immune checkpoints therapy in malignant tumors

Immune checkpoint inhibitors (ICT) therapy is a successful immunotherapy (IT) strategy that is quite effective in a number of patients with non-small cell lung cancer, melanoma, bladder cancer, breast cancer and others. Nevertheless, there is a need in predictive markers for ICT therapy for personalized IT as far as there is a large group of patients, the proportion of which varies depending on the tumor, who do not have a clinical response to such therapy. The review summarizes the theoretical aspects and results of clinical trials dedicated to various clinical efficiency predictor using modern databases. As a result of the analysis it is established that the main candidates for the role of such markers are tumor infiltrating lymphocytes and their subpopulations, peripheral blood lymphocytes (PBL) and their subpopulations. PD1 (programmed death receptor 1) and PDL1 (programmed death receptor ligand 1) expression in tumor tissue can also be important for predicting IT efficiency. The most promising predictive biomarker meaning the most clinically relevant is a combination of the PBL subpopulations study and PD1 and PDL1 expression on the tumor cells.PubMed, Scopus, Web of Science, eLibrary, Russian Science Citation Index databases were searched for the available appropriate literature reports. The authors included 82 in the given review.
