The problem of human individual development requires not just the accumulation and generalization of data, but also clarification, a systematic understanding of the individual variability of higher mental functions in relation to environmental factors and taking into account the risks associated with their formation.The aim: to identify systematic patterns of correlation between individual variability of higher mental functions of preschool children and the material prosperity of their families.Methods. Traditional neuropsychological tests developed by A.R. Luria and adapted in the neuropsychology laboratory of the Faculty of Psychology at Lomonosov Moscow State University were used. We examined 180 preschool children from families with high, average, and low income.Results. The greatest individual variability in the period of preschool age in relation to the level of material prosperity of the family, are the functions with a long period of formation, these are functions of block III of the brain, and the functions provided mainly by the left hemispheric parts of the brain. Children from the most affluent families have the highest indices of brain block III functions (p < 0.001) and left hemispheric functions (p < 0.001). Preschoolers from low-affluence families had indexes of both front brain function (p < 0.001) and left hemispheric function (p < 0.001) in the zone of negative values.Conclusion. The empirical results of the study allow us to clarify that the factor of material prosperity of the family, both directly, factor-wise, and indirectly, cumulatively, through the system of proximal factors, can make its selective contribution to the variability of indicators of children’s higher mental functions.

Background. Overweight and obesity significantly increase the risk of premature death and the development of chronic diseases. Many anthropometric indices have been developed to verify obesity, although the best among them still remains undetermined.The aim. To determine the sex and age specificities of the dynamics of anthropometric indicators characterizing obesity.Materials and methods. The program was implemented in the period from 2015 to 2020. It provided for the implementation of a sample research. The baseline research included 1,124 women and 476 men. The average age was 54.9 ± 9.75 years and 52.6 ± 10.0 years, respectively. To identify gender specificities, all participants were divided into three age groups: 35–49 years old, 50–59 years old, and 60–70 years old. The observation period was 3 years. To determine the level of visceral fat, the VS-532 fat mass analyzer (Tanita Health Equipment HK Ltd., Hong Kong) was used. Body mass index (BMI), waist-hip index (WV/HV), visceral obesity index (VOI) were also calculated. Statistical processing of the results was carried out using the program Statistica 6.0 (StatSoft Inc., USA).Results. New cases of obesity developed in 30.6 % of the surveyed. There was an increase in the prevalence of obesity according to the criteria of WV (by 8.9 %) and VFL (by 5.4 %) and a decrease in the number of people who are obese according to WV/HV – by 4.2 %. Of all the indicators, only VOI showed a statistically significant decrease in the mean values over the observed period, while BMI, WV and VFL showed an increase.Conclusions. It is necessary to apply various criteria for the diagnosis of obesity, since individual indices are not able to fully reflect the gender and age specificities of the distribution of fat in the body

Background. In Russia, of all detected cases of COVID-19, 18 % were in the pediatric population. According to a number of studies, adolescents develop long-term clinical and psychological consequences after an illness. Therefore, at present, the most relevant is a thorough study of the structure and severity of consequences of COVID-19 in adolescents.The aim of the research was to assess the severity of consequences of COVID-19 in adolescents depending on the time period after diseases.Methods. The sample included 96 people aged 11–16 years: 48 adolescents who have undergone COVID-19 (main group); 48 adolescents who did not have COVID-19 (control group). The main group was divided into six subgroups, depending on the period after COVID-19. The following research methods were used: clinical history using a standardized interview method; “Correction test” method by B. Bourdon; Beck’s Depression Inventory (BDI-1A); Adolescent’s Form of Manifest Anxiety Scale by A.M. Prikhozhan.Results. Clinical symptoms of COVID-19 during the acute phase of the disease were considered in adolescents. It has been established that the most common symptoms include fever, runny nose, cough, sore throat, severe fatigue, impaired sense of smell, impaired taste, headache (most often localized in the frontal region). Clinical and psychological symptoms characteristic of post-COVID syndrome were considered as consequences of COVID-19 in adolescents. The majority of the examined adolescents showed the following clinical symptoms of COVID-19 after discharge: asthenia, disturbances of smell and taste; lasting from 2 to 64 weeks. As psychological symptoms, adolescents were characterized by reduced attention span, reduced speed of information processing and concentration, as well as the presence of symptoms of severe depression and high anxiety. During the second month after COVID-19, the most unfavorable emotional state was revealed in adolescents.Conclusions. The data obtained made it possible to determine that post-COVID syndrome in adolescents is characterized by the presence of an asthenic condition, impaired attention, high anxiety, severe depressive symptoms.

Background. Performing penetrating keratoplasty in 100 % of cases leads to the occurrence of induced postkeratoplasty astigmatism, which can be more than 12,0 D. If cataracts occur in this category of patients, performing cataract phacoemulsification with implantation of a toric intraocular lens (tIOL) does not completely solve the problem. The use of the method of implantation of intrastromal corneal segments at stage I before cataract phacoemulsification makes it possible to reduce the degree of postkeratoplasty astigmatism and create optimal conditions for additional correction of residual postkeratoplasty astigmatism due to the implantation of tIOL during cataract phacoemulsification.The aim. To analyze the clinical and functional indicators of correction of regular high-grade postkeratoplasty astigmatism in a patient with cataracts using a combined method, including first implantation of intrastromal corneal segments and subsequent cataract phacoemulsification with implantation of toric intraocular lens using the example of a clinical case.Material and methods. A 55-year-old patient with cataracts, who had a history of undergoing penetrating keratoplasty, contacted us. According to the keratotopogram data, a regular postkeratoplasty astigmatism of 18.68 D was diagnosed. The patient underwent a combined method. At stage I, intrastromal corneal segments were implanted into the corneal graft, then after 6 months stage II was performed – cataract phacoemulsification with implantation of tIOL.Results. Six months after intrastromal corneal segments implantation, the patient’s keratometric data stabilized, and corneal astigmatism decreased to 8.98 D. Then the patient underwent cataract phacoemulsification with tIOL implantation. After 1 month, the spherical component of refraction was 0.5 D, the cylindrical component of refraction was –0.5 D, visual acuity increased to 1.0.Conclusions. A combined method for correcting regular high-grade postkeratoplasty astigmatism in a patient with cataracts showed high refractive results, stability and safety in the long-term postoperative period.

Background. The use of complexes of synthetic and herbal remedies as hepatoprotectors in the treatment of liver pathologies of various etiologies is an urgent task of pharmacology. A promising type of medicinal plant raw material is an extract of Hippophaes rhamnoides leaves. The hepatoprotective effect of extract of Hippophaes rhamnoides leaves in combination with ademethionine has not been studied to date.The aim of the research was to study changes in biochemical markers of hepatic function in the application of complex schemes of pharmacotherapy of experimental liver damage with paracetamol using Extractum foliorum Hippophaes rhamnoides.Materials and methods. The experimental study was performed on Wistar rats, the animals were divided into six groups. Group 1 (intact) – animals without a model of liver damage and without treatment; in Group 2 (control) paracetamol was used to create experimental hepatitis without treatment (positive control group); in Group 3 (comparison) a combination of “silibinin + ademethionine” was used on a model of paracetamol hepatitis; in Group 4 (experimental) extract of Hippophaes rhamnoides leaves was used on the model of paracetamol hepatitis; in Group 5 (experimental) ademethionine was used on a model of paracetamol hepatitis; in Group 6 (experimental) a combination of extract of Hippophaes rhamnoides leaves and ademethionine was used on a model of paracetamol hepatitis. The functional state of the liver of experimental animals was determined by biochemical parameters.Results. When using a combination of extract of Hippophaes rhamnoides leaves with ademethionine, the studied biochemical parameters significantly (p < 0.05) differed from the numerical values in the negative control group and were closest to those in the intact group than in other experimental groups.Conclusions. A comparison of the effectiveness of the use of extract of Hippophaes rhamnoides leaves in combination with ademethionine by the total effect on blood biochemical parameters determines this complex as a promising drug for further research.

Background. In the pathogenesis of ischemic cardiomyopathy (ICMP), angiopoiesis remains unexplored.The aim. To describe the vasculature of the heart and the imbalance of angiogenesis mediators in the coronary circulation in association with the number of endothelial progenitor cells (EPC) and desquamated endothelial cells (DEC) in the blood of patients with coronary heart disease (CHD), suffering and not suffering from ICMP.Methods. Fifty-two patients with CHD (30 patients with ICMP, 22 patients without ICMP), 15 healthy donors were examined. The content of EPC (CD14+CD34+VEGFR2+) in the blood from the cubital vein and DEC (CD45–CD146+) in the blood from the coronary sinus and the cubital vein was determined by flow cytometry. The concentrations of VEGF-A (vascular endothelial growth factor A), PDGF (platelet-derived growth factor), and SDF-1 (stromal cell-derived factor 1) in blood plasma were recorded using immunofluorescence assay; the angiopoietin-2, MMP-9 (matrix metallopeptidase 9) were recorded using enzyme immunoassay. In myocardial biopsies the specific area of vessels and the expression of αSMA (smooth muscle alpha-actin) were determined by morphometric and immunohistochemical methods.Results. In the peripheral blood of patients with CHD, regardless of the presence of ICMP, the DEC content exceeded the physiological level, and the VEGF-A, PDGF, angiopoietin-2, and MMP-9 corresponded to the norm. In CHD patients without cardiomyopathy, there was an excess of SDF-1 and EPC in the blood from the cubital vein, and in ICMP, their physiological significance was noted. In the coronary blood flow in patients with CHD without cardiomyopathy, an increase in the concentration of PDGF was found, which was not determined in patients with ICMP, who had an increased content of DEC, angiopoietin-2 and MMP-9. The specific area of the vessels in the patients of the two groups was comparable; the expression of αSMA in ICMP was 6.2 times lower than in patients with CHD without cardiomyopathy.Conclusion. The development of ICMP is accompanied by impaired maturation of vessels in the myocardium, associated with the absence of a compensatory reaction of activation of cellular and humoral factors of angiogenesis.

Background. During the ongoing COVID-19 pandemic and in the season of rising incidence of other respiratory infections, it is relevant to use preventive measures of non-specific prophylaxis. Synthetic peptides are widely considered as a tool. The representative of this group is the synthetic analogue of thymus regulatory peptides Thymogen, which has been used in Russia for more than 20 years in the treatment of acute and chronic infection diseases.The aim of the study. To evaluate the effect of Thymogen, a dosed nasal spray, on induced parameters of the immune system during prophylactic use in healthy volunteers.Materials and methods. Twenty healthy volunteers received Thymogen nasal dosed spray (JSC “Cytomed”, Russia) at a dose of 25 μg twice a day for 10 days. A comparative assessment of immunological parameters was carried out in dynamics: before the start of therapy, on days 6 and 11 of taking the drug and 14 days after the end of the course. Clinical observation was carried out from day 1 to day 11, registration of adverse events – the entire period of the study for 24 days. The first day was considered the day the drug was started.Results. In the course of the work, according to the data of immunological examination, a statistically significant increase in the virus-induced production of interferon alpha (INF-α) by a culture of peripheral blood cells was revealed. The growth rate was recorded on day 11 of taking Thymogen and persisted for 14 days after the end of the course. Significant differences in the dynamics of bactericidal and phagocytic activity of neutrophils, serum α- and γ-interferon were not obtained.Conclusion. The use of Thymogen spray at a dose of 25 μg for 10 days was safe and contributed to a significant induction of interferon-alpha in response to exposure to a viral pathogen, which allows us to recommend the drug for prophylactic use during the period of rising incidence of acute respiratory diseases.

During the ongoing COVID-19 pandemic and in the season of rising incidence of other respiratory infections, it is relevant to use preventive measures of non-specific prophylaxis. Synthetic peptides are widely considered as a tool. The representative of this group is the synthetic analogue of thymus regulatory peptides Thymogen, which has been used in Russia for more than 20 years in the treatment of acute and chronic infection diseases.The aim of the study. To evaluate the effect of Thymogen, a dosed nasal spray, on induced parameters of the immune system during prophylactic use in healthy volunteers.Materials and methods. Twenty healthy volunteers received Thymogen nasal dosed spray (JSC “Cytomed”, Russia) at a dose of 25 μg twice a day for 10 days. A comparative assessment of immunological parameters was carried out in dynamics: before the start of therapy, on days 6 and 11 of taking the drug and 14 days after the end of the course. Clinical observation was carried out from day 1 to day 11, registration of adverse events – the entire period of the study for 24 days. The first day was considered the day the drug was started.Results. In the course of the work, according to the data of immunological examination, a statistically significant increase in the virus-induced production of interferon alpha (INF-α) by a culture of peripheral blood cells was revealed. The growth rate was recorded on day 11 of taking Thymogen and persisted for 14 days after the end of the course. Significant differences in the dynamics of bactericidal and phagocytic activity of neutrophils, serum α- and γ-interferon were not obtained.Conclusion. The use of Thymogen spray at a dose of 25 μg for 10 days was safe and contributed to a significant induction of interferon-alpha in response to exposure to a viral pathogen, which allows us to recommend the drug for prophylactic use during the period of rising incidence of acute respiratory diseases.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"67 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139530762","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}

Background. The most severe category of fractures of the proximal humerus are intra-articular injuries which are accompanied with humeral head ischemia caused by an injury and aggravated by surgical intervention. Due to frequent disruption of vascularization with subsequent necrosis of the humeral head, there is a need to stimulate reparative osteogenesis in intra-articular injuries to prevent ischemic changes in the humeral head. The aim of the study. To improve the results of surgical treatment of intra-articular fractures ofthe proximal humerus based on the development of a new osteosynthesis technique using non-free osteomuscular graft. Material and methods. We analyzed the results of treatment of 48patients with 11- C1 and 11-C2 intra-articular fractures of the proximal humerus, who had hospital treatment at the emergency department of traumatology of the Novosibirsk City Clinical Hospital No. 1 and were subsequently observed on an outpatient basis. An analysis of literature data using search words was carried out in the PubMed and eLibrary databases. Results. According to the data obtained during the study, the functional and radiological results of the patients who were treated using the method of reparative stimulation with a non-free osteomuscular graft from the coracoid process are statistically significantly higher than the results of the control group. Conclusion. Using autoplasty with a non-free osteomuscular graft from the coracoid process improves the results and reduces the risk of developing post-traumatic aseptic necrosis of the humeral head.

Background. In 15–25 % of cases, the cause of primary hyperparathyroidism (PHPT) is multigland parathyroid disease. The complexity of clinical and laboratory prognosis, low efficiency of imaging methods, inaccurate assessment of the radicality of the surgery are the components of the problem of this variant of the disease. Quality of life (QOL) is an important criterion for the effectiveness of surgical treatment. A study of the QOL in patients with multigland parathyroid disease in PHPT has not been previously conducted in our country. The aim of the study. To assess the quality of life of patients with single- and multigland parathyroid disease in sporadic primary hyperparathyroidism before and after parathyroidectomy (PTE). Methods. As part of a prospective observational study, the quality of life of 64 patients with PHPT before and after PTE was assessed using SF-36 (Short Form 36) questionnaire: main group (n = 13) – patients with multigland parathyroid disease; comparison group (n = 51) – patients with single-gland parathyroid disease. The quality of life indicators of the patients were compared with those in a sample of the Irkutsk region population similar in gender and age. Results. Before performing PTE, the quality of life of patients with PHPT was lower than that of the Irkutsk region population. The greatest decrease in both health components was registered in the main group. In 90 % of patients, the quality of life improved after PTE, while in the main group changes were established 1 year after the surgery, in the comparison group – 6 months after the surgery. Transient complications (laryngeal paresis) and disease outcomes (hypocalcemia, hypoparathyroidism) did not interfere with the improvement of quality of life in both groups. When persistence was detected, no significant improvement in QOL was established. Conclusion. The quality of life of patients with PHPT is significantly reduced. PTE improves the QOL of these patients, and only persistence of the disease does not allow this to be achieved. Therefore, surgical tactics aimed at reducing the frequency of persistence will achieve a decent quality of life in the majority of patients with multigland parathyroid disease in PHPT.

Background. Among patients who have undergone coronary artery bypass surgery (CABG), the proportion of people with diabetes mellitus (DM) is about 40 %. To date, the problem of choosing the optimal method of surgical myocardial revascularization, which can provide the best result in this cohort, remains completely unresolved. The aim of the study. To assess the in-hospital and long-term results of bimammary and traditional bypass surgery in patients with type 2 diabetes mellitus. Methods. From September 2018 to December 2021, 176 CABG surgeries were performed in patients with coronary heart disease (CHD) and type 2 diabetes at the Federal Center for Cardiovascular Surgery (Krasnoyarsk). Group 1 (n = 45) included patients who underwent myocardial revascularization using two mammary arteries; group 2 (n = 131) included patients who underwent myocardial revascularization using traditional technique. After propensity score matching, 45 patients were selected into each group, comparable by basic preoperative characteristics. Results. In group 1, cardiopulmonary bypass surgeries were performed in 23 (51.1 %) patients (group 1CPB), off-pump surgeries – in 22 (58.2 %) (group 1OP); in group 2, all patients underwent cardiopulmonary bypass surgeries. Hospital mortality was recorded in group 2 in 1 (2.2 %) case. Deep sternal infection developed in 1 (4.5 %) patient in group 1OP. Long-term survival in group 2 was 85.3 %, in group 1CPB – 83.3 % (p = 0.689), in group 1OP – 84.2 % (p = 0.739). 84.2 % of patients in group 2 and 100 % in groups 1CPB and 1OP had no cardiovascular events (p = 0.144 and p = 0.145, respectively). Conclusion. Bimammary bypass surgery in patients with type 2 diabetes is a safe and effective method of surgical treatment of coronary artery disease in both shortand long-term period and may be the operation of choice in patients with multivessel disease. There were no differences in patient survival up to 45 months; bimammary revascularization was associated with 100 % absence of cardiac mortality.
