The article presents an analysis of thyroid hormones’s action mechanism as the organism’s response to environmental stress.

The literature analysis was performed using the PubMed, SpringerLink, eLibrary, GoogleScholar databases for relevant publications for the period 2015–2023. Results and discussion. The development of both hypo- and hyperthyroidism negatively affects the functioning of a number of organs and systems of the organism. The consequences of changes in the level of thyroid hormones in the form of hypo- and hyperthyroidism for the adaptive capabilities of the organism are characterized, and the possibilities of correcting adaptive reactions by regulating their level are analyzed. Conclusions. To date, it has been proven that thyroid hormones are actively involved in the expression of more than 100 genes, maintaining redox balance, as well as in many metabolic reactions, which affects the adaptive potential of the organism. At the same time, the development of both hypo- and hyperthyroidism negatively affects the functioning of a number of organs and systems of the organism. Therefore, for a person to successfully adapt to stressful environmental factors, it is advisable to correct the content of iodothyronines in the organism. Actively used hormonal support, despite proven effectiveness, has nevertheless a number of limitations regarding the potential harm of such therapy, as a result of which approaches to correcting the content of iodothyronines are currently being analyzed, in particular, through the nutritional intake of a number of vitamins and microelements, as well as through dosed physical activity.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682608","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}

Material and methods. 296 medical students were examined using the online survey method: 219 Russians (main group) and 77 foreigners (comparison group); 107 (36.2 %) boys and 189 (63.8 %) girls; age 20 [18; 21] years (median [lower quartile; upper quartile]). The structure of online behavior was assessed: adaptive, non-adaptive, and pathological (PIU) Internet use; specific forms of PIU: problematic use of computer games and social networks, mixed and undifferentiated form of PIU. The values of the total score of the scales of the applied psychometric questionnaires were determined. The indicators were compared in the general group of subjects, in groups of Russians and foreigners, including gender. Results. Problematic smartphone use is typical for 14.2 % of all surveyed. The share of smartphone addicts is higher among foreigners than among Russians (27.3 and 8.0 %, respectively), both boys and girls. PIU prevailed among foreigners (16.1 and 7.4 %), they are more often dependent on social networks (34.5 and 2.4 %). Foreign women were distinguished by a high incidence of problematic use of computer games (20.0 and 3.6 %) and social networks (25.0 and 3.1 %), as well as a mixed form of PIU (20.0 and 2.5 %). The content consumed by Russians (boys + girls) was dominated by being on social networks (77.6 Russians and 46.7 % foreigners) and listening to music (50.7 and 31.2 %, respectively). Gender differences in content included more frequent use of social networks by Russian students, both boys (81.1 and 48.1 %) and girls (76.5 and 43.5 %); more frequent listening to music by Russian males in comparison with foreign males (66.0 and 29.6 %) and Russian females (66.0 and 45.8 %). Foreign boys use smartphones for games more often than foreign girls, the preoccupation with smartphone games is higher among Russian women as well. Conclusions. The prevalence of problematic smartphone use, the characteristics of the content consumed and associations with other forms of PIU among Russian and foreign students were established. In our opinion, it is necessary to carry out further research aimed at solving an urgent medical and social problem of timely diagnosis of smartphonedependent behavior and prevention of somatic and neuropsychic health disorders associated with it in young people.

In spite of significant achievements of scientists in the field of medicine and pharmacology, existing steroid and nonsteroidal antiinflammatory drugs have a number of undesirable reactions. To date, one of the most urgent directions is the search for new effective and safe drugs with anti-inflammatory activity. The aim of the study was to investigate the anti-exudative properties of new 3-cyano-1,4-dihydropyridines, cyanothioacetamide derivatives in the classical test of acute formalin edema. Material and methods. The study was conducted on 88 white rats weighing 210–250 g. The effectiveness of compounds was determined in a model of acute formalin edema, which was induced by subplantar injection of 0.1 ml of 2 % formalin solution into the right hind limb of the animals. The severity of exudation was evaluated oncometrically in comparison with reference drugs – ibuprofen, indomethacin, meloxicam and metamizole sodium. The studied substances were administered intragastrically at a dose of 5 mg/kg 1.5 hours before the induction of inflammation. Results. It was found that some compounds exhibit anti-exudative activity, more pronounced or similar to the activity of reference drugs. The laboratory sample with code mar-137 was the leading sample and outperformed the comparators; 24 hours after the modeling of edema, it exceeded ibuprofen (by 2.39 %), metamizole sodium (by 4.77 %) in anti-exudative efficacy and had an anti-inflammatory effect similar to the activity of indomethacin and meloxicam.

Material and methods. As part of a quantitative online survey conducted from September to December, 2022, 104 respondents working in the healthcare system of the Russian Federation were interviewed. Additionally, 6 in-depth interviews were conducted with the organizers and experts of the healthcare sector as part of a qualitative sociological study. Desk research included analysis of scientific literature, and the regulatory framework related to the introduction of a risk-based approach to healthcare. Results and discussion. The article presents an analysis the perception of risks in healthcare by doctors, organizers and experts at the level of a medical organization, of the healthcare system and of public health (macro level), with the identification and classification of the main risk groups, on the basis of which risk-management’ measures can be built. The results of the study testify to the insufficiently deep introduction of risk management into the management system of medical organizations. The half of the respondents noted the low and extremely low level of risk management principles’ usage in their own organizations (50 % of respondents) and in Russian medical organizations in general (58.6 % of respondents). At the same time, from a third to a half of the participants found that it was difficult to answer about risk management implementation in their organizations, due to the lack of a unified methodology, imperfection of standards and quality control system of this set of measures, lack of specialists who could manage risks, lack of educational activities. To introduce a systematic approach to the unification of risk management processes, it is necessary to develop and approve the methodology of best practices, as well as take care of the training of specialists. Conclusions. In order to implement a systematic approach to the unification of risk management processes, it is necessary to develop and approve a methodology of best practices, as well as to take care of the training of specialists. It is imperative that hospital managers and staff focus on improving the organizational culture of patient safety management as the basis for their mission to preserve public health.

Material and methods. The study included 4 male mice of each inbred strain C57BL/6 and BALB/c at the age of 12 weeks. The brain and cerebrospinal fluid system images were obtained using an 11.7 T horizontal MR scanner (Bruker, BioSpec 117/16 USR, Germany). An axial section at the level of -0.5 mm from bregma was chosen as the geometry for mathematical modelling. To describe the data obtained, the mathematical model was adapted by selecting a scale factor based on the known values of the cerebrospinal fluid formation rate for humans and mice. Results and discussion. The same qualitative pattern of relationship between capillary pressure and mean ventricular wall displacement was observed for all animals considered. Although the selected genetic strains of BALB/c and C57Bl mice differ significantly in terms of cerebral ventricle size, these differences in animal genotype did not affect the nature of this relationship. Changing the parameters of the fluid media interaction in the area of compression or moderate ventricular dilation almost does not lead to an exit from the physiologically acceptable capillary pressure value. In this case, the size of the ventricles changes significantly. In the area of large ventricular dilation, in contrast, there is little change in ventricular size, and this is accompanied by a dramatic increase in capillary pressure far beyond physiologic limits. Thus, the change in ventricular size is an adaptive process associated with pressure fluctuations caused by changes in intracranial fluid flow. The mere fact that some of the values reach the zone of physiologically unacceptable pressures associated, in fact, with death, provided that there is practically no change in ventricular size indicates that such a situation is rarely realized and is possible in case of violation of intracranial fluid media flows associated with the fact that the increase in ventricular size limits adaptive capabilities. Conclusions. The presented animal model will further increase the understanding of the pattern we have established and allow us to move on to attempts at prediction.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258456","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}

It is noted that the most common infectious diseases in patients with diabetes mellitus are infections of the respiratory and urinary tract, skin and soft tissues, diabetic foot ulcers, otitis media and periodontal infections. Antimicrobial agents can have both direct and indirect hypoglycemic effects. Quinazolinones belonging to the group of heterocyclic derivatives exhibit a wide range of pharmacological activity. The use of the PASS program for the purpose of computer prediction of pharmacological activity showed a high probability of the hypoglycemic effect of new derivatives. The obtained results motivated the authors to search for the relationship between antimicrobial action and hypoglycemic effect within the general direction of studying the multi-targeting of drug ligands. Analysis of the literature data, as well as own studies of new quinazolinone derivative pharmacological activity make it possible to divide all ligands into functional groups that cause additional binding to the target molecule. The quinazolinone fragment, characterized by the uniqueness of its structure, can be reasonably attributed to multi-target ligands. The triazole cycle and the sulfonamide group can also purposefully bind to the target molecule. A carbamide residue, a fragment of sulfonylurea and an acetamide group, depending on the structure of the substance they are part of, can function both as a specific ligand and as a functional group involved in the stabilization of the intermediate transition state. The results obtained by the authors, as well as other researchers, allow us to formulate an assumption about the relationship between the mechanisms of antimicrobial and hyperglycemic activity.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140259592","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}
