RESUMO
The article presents results of sociological analysis of social health of modern student youth. The empirical basis of study was composed with results of monitoring study of student youth carried out by sociological laboratory of the Department of Sociology and Social Technologies. Within a framework of sociological monitoring, were evaluated such components of social health of student youth as relationships with friends and relatives, relationships in student community, inter-ethnic relations in University and region, participation in public life, social well-being, active life position and family practices and values. It is established that modern possibilities of living conditions allow each person to organize one's life-style in such a way as to develop synergetic effect for social health, combining achieved standards of organization of everyday life and fashion for healthy lifestyle. It is namely such synergistic effect can be enhanced and induced in social environment. The main role at that is played by namely large multi-generational family.

We studied the effect of enteral administration of GABA on the gastric mucosa in male Wistar rats (n=47) with modeled metabolic stress (food deprivation for 9 days with free access to water). The relative weights of the adrenal glands and thymus were determined, and histological examination of the stomach was performed. In control rats, modeling the metabolic stress was accompanied by the development of erosive damage to the gastric mucosa related to blood supply disturbances. Administration of GABA prevented erosions and exhibited a pronounced gastroprotective effect. Thus, administration of GABA can be a promising method for the prevention and treatment of erosive gastric lesions associated with metabolic stress.

OBJECTIVE: To investigate the efficacy and safety of Aviandr in the treatment of anxiety in patients with adjustment disorders after COVID-19. MATERIAL AND METHODS: A multicenter prospective open-label study included 109 patients of both sexes aged 18 to 65 years (70 women, 39 men, average age - 41.4±13.18 years) with a leading complaint of anxiety (Hamilton scale score, HAM-A ≥18 - ≤24), which arose after acute coronavirus infections. Clinical manifestations had to meet the diagnostic criteria F43.2 ICD-10. The drug Aviander was prescribed 20 mg 2 times a day for 4 weeks. At the end of taking the drug, patients were monitored for another 1 week (a delayed follow-up visit). Psychopathological, statistical and parametric research methods were used using standardized HAM-A, Montgomery-Asberg scales (MADRS), visual analog asthenia scale (VASH-A), Sheehan Disability Scale (SDS), digital character substitution test (DSST), general clinical impression scale (CGI). RESULTS: Data from 109\110 patients were analyzed to evaluate efficacy\safety. Aviandr was administered 20 mg 2 times daily for 4 weeks. Patients were followed for 1 week (delayed follow-up visit) at the end of treatment. Reducing the intensity of anxiety on the HAM-A scale was - 14.2±4.92 or 69.4±22.66% by the end of treatment. The response rate to therapy (responders are patients with a decrease in the total score on the HAM-A ≥50%) was 83.49%. Remission was achieved (sum of HAM-A scores ≤7) by the end of treatment 68.81% of patients, and 79.8% of patients at the follow-up visit. Significant changes were obtained on the MADRS, VAS-A, SDS and DSST scales. According CGI 45.9% of patients had «much improved¼ and 43.1% of patients had «very much improved¼ by the end of treatment; 58.7% of patients had «much improved¼ and of 33.9% patients had «very much improved¼ at the follow-up visit. 38 adverse events were reported in 27 (24.55%) patients during the study. A definite association with study drug was reported between 5 mild adverse events in 4 (3.64%) patients. No subjects withdrew from the study due to an adverse event. Positive dynamics (reduction of anxiety symptoms, decrease in asthenia) persisted after discontinuation of the study drug. No cases of withdrawal syndrome were observed. CONCLUSION: According to the results of the study, the anxiolytic, antidepressant, antiasthenic and pro-cognitive effects of Aviandr were observed. An increase in the social activity of patients was observed.

Acute coronary events (ACEs) associated with a SARS-CoV-2 infection can significantly differ from classic ACEs. New biomarkers, such as ceramides, may help in the diagnosis and treatment of this disease. This study included 73 ACE patients for whom the SARS-CoV-2 infection was verified. Two subgroups were formed: the favorable outcome subgroup and the fatal outcome subgroup. Plasma samples were collected from all patients at the time of admission for a metabolomic analysis. The analysis of metabolites revealed that the ceramide levels were significantly lower in the fatal outcome subgroup than in the survivor subgroup. Therefore, determining ceramide levels in patients with ACEs in conjunction with COVID-19 may help assess the prognosis of these patients and manage their risks.
RESUMO
One of the main causes of the of the inner ear pathology is a viral infection including SARS-CoV-2 virus. On the other hand the psycho-emotional state of patients also affects patients with hearing loss, tinnitus and dizziness, and an increase in depression and anxiety was revealed during the period of self-isolation. Goal of our study was to analyze cochleovestibular pathology in patients with COVID-19. The study involved 84 patients and the leading complaint was hearing loss - in 70 patients, tinnitus - in 54 patients, dizziness - in 50 patients. In addition, an increased anxiety background was found in patients, as well as signs of depression. Thus, the 2020 pandemic period was a high risk period for patients with inner ear pathology, which may be associated not only with the actual pathological effect of the virus on the auditory and vestibular system, but also with changes in the psycho-emotional status of patients.

OBJECTIVE: To evaluate the experience of prescribing phenosanic acid in the practice of a neurologist/epileptologist when prescribing the second, third anticonvulsant drug (AED) as part of combination therapy for patients with manifestations of fatigue due to epilepsy. MATERIAL AND METHODS: 501 patients with focal epilepsy accompanied by asthenic disorders were included in the observational program. The observation program protocol included 5 visits, including visit 1, at which screening and inclusion in the OP took place. The observation period was 10 months. At baseline and at the end of the 10-month follow-up, the patients' condition was assessed according to the following indicators: frequency and transformation of attacks with focal onset, severity of fatigue (self-assessment scale MFI-20); quality of life (questionnaire QoLiE-10-P); frequency of attacks with focal onset. The safety of phenosanic acid (Dibufelon) was also assessed. RESULTS: In 10 months after the inclusion of Dibufelon as the 2nd, 3rd AED in the treatment regimen, a statistically significant (p<0.01) decrease in the frequency of seizures was observed: in general - in 88% of patients; by 50% or more - in 76% of patients; transition from the group with a large number of seizures to the group with a smaller number of seizures - 74% of patients. Also when taking phenosanic acid, a positive dynamics of seizure type was noted: a reliable decrease in the proportion of patients with seizures with secondary generalization from 70% to 56%; a decrease in the number of focal seizures with impaired consciousness from 65% to 53%. In addition, there was a 38% decrease in the severity of fatigue on the MFI-20 scale (the greatest decrease on the «Mental fatigue¼ scale), improvement in the quality of life - a 2.7-fold increase in the mean values of the QOLIE-10 questionnaire. CONCLUSION: The addition of phenosanic acid to antiepileptic therapy as a second or third AED allows for better control of seizures, leading to a decrease the frequency and severity of attacks and the severity of fatigue both, and an increase of the quality of life of patients with epilepsy.

We compared the immunogenicity of recombinant S. pneumoniae pneumolysin (rPly) when administered with and without Al(OH)3 adjuvant, and evaluated the protective properties of recombinant protein in the active defense experiment. It was shown that double immunization with rPly+Al(OH)3 increases the levels of IgG antibodies in comparison with the control (p<0.01), while triple immunization results in a more significant increase in IgG antibody levels (p<0.001). Double immunization with rPly without Al(OH)3 does not induce a significant increase in antibody levels in comparison with the control, while triple immunization results in a slight but significant increase in antibody levels (p<0.05). The active defense test proved the protective activity of rPly against S. pneumoniae serotype 3 at intranasal infection.

The efficiency of combinations of cytostatics cisplatin and adriamycin with antioxidant sodium 3-(3'-tert-butyl-4-hydroxyphenyl)propyl thiosulfate (TS-13), and nitric oxide (NO) donor NaNO2 was evaluated on two drug-resistant strains of leukemia P388 with changed redox-status of cells. Simultaneous use of both NO donor and TS-13 in combinations with the cytostatics did not increase the efficiency of therapy. In addition, antioxidant activity of TS-13, NaNO2, and their combinations was studied by the method of luminol-dependent chemiluminescence on the model systems with the use of the homogenized cells of sensitive strain and two drug-resistant strains of leukemia P388. It was shown that TS-13 and NO donor produced opposite effects: TS-13 decreased, while NO donor increased the content of free radicals in the model system. Combinations of antioxidant TS-13 and NO donor should be used with consideration for the redox-status of tumor treated.

Dysembryoplastic neuroepithelial tumor (DNET) is a benign mixed neuronal-glial neoplasm (WHO grade 1). DNET is most often localized in temporal lobes and found in children and young people with epilepsy. There a few cases of DNET in ventricular system with dissemination along the ependyma in the world literature. MATERIAL AND METHODS: We present a rare case of T1- and T2-negative ventricular system tumor. Only FIESTA imaging revealed dissemination with multiple focal lesions of the third ventricle, its bottom and lateral walls, anterior horns of lateral ventricles, cerebellar vermis, cervical and lumbar spinal cord. RESULTS: The patient underwent transcortical endoscopic biopsy of the third ventricle tumor with simultaneous ventriculoperitoneal shunting. DNET was diagnosed, and radiotherapy was subsequently performed. Literature data on this issue were analyzed. CONCLUSION: To date, disseminated forms of DNET are extremely rare. X-ray features and morphological results allow us to establish the correct diagnosis and determine further treatment strategy.

BACKGROUND: In recent years, prolonged states of impaired consciousness became widespread among patients with aneurysmal subarachnoid hemorrhage. Treatment and maintenance of vital functions in such patients represent a complex medical, economic and social problem. In this regard, searching for the causes of prolonged states of impaired consciousness and predicting the outcomes are important. OBJECTIVE: To analyze available literature data on prevention and treatment of prolonged states of impaired consciousness after aneurysmal subarachnoid hemorrhage. RESULTS: We reviewed the PubMed database using the keywords «unresponsive wakefulness syndrome¼, «persistent vegetative state2, «minimal consciousness state¼ and «outcome of subarachnoid hemorrhage¼. Only 4 reports devoted to the causes and treatment outcomes in patients with prolonged impairment of consciousness after aneurysmal subarachnoid hemorrhage were found. At the same time, patients with aneurysmal subarachnoid hemorrhage comprise up to 11% among all cases of prolonged states of impaired consciousness. Examination, management and treatment of patients with prolonged impairment of consciousness after aneurysmal subarachnoid hemorrhage are carried out according to general principles without taking into account specific etiological and pathogenetic factors. CONCLUSION: Increased number of patients with prolonged impairment of consciousness after aneurysmal subarachnoid hemorrhage necessitates analysis of etiopathogenesis and outcomes of these disorders based on modern clinical, instrumental and laboratory assessment of the brain.

Single-nucleotide polymorphisms (SNPs) can serve as reliable markers in genetic engineering, selection, screening examinations, and other fields of science, medicine, and manufacturing. Whole-genome sequencing and genotyping by sequencing can detect SNPs with high specificity and identify novel variants. Nonetheless, in situations where the interest of researchers is individual specific loci, these methods become redundant, and their cost, the proportion of false positive and false negative results, and labor costs for sample preparation and analysis do not justify their use. Accordingly, accurate and rapid methods for genotyping individual alleles are still in demand, especially for verification of candidate polymorphisms in analyses of association with a given phenotype. One of these techniques is genotyping using TaqMan allele-specific probes (TaqMan dual labeled probes). The method consists of real-time PCR with a pair of primers and two oligonucleotide probes that are complementary to a sequence near a given locus in such a way that one probe is complementary to the wild-type allele, and the other to a mutant one. Advantages of this approach are its specificity, sensitivity, low cost, and quick results. It makes it possible to distinguish alleles in a genome with high accuracy without additional manipulations with DNA samples or PCR products; hence the popularity of this method in genetic association studies in molecular genetics and medicine. Due to advancements in technologies for the synthesis of oligonucleotides and improvements in techniques for designing primers and probes, we can expect expansion of the possibilities of this approach in terms of the diagnosis of hereditary diseases. In this article, we discuss in detail basic principles of the method, the processes that influence the result of genotyping, criteria for selecting optimal primers and probes, and the use of locked nucleic acid modifications in oligonucleotides as well as provide a protocol for the selection of primers and probes and for PCR by means of rs11121704 as an example. We hope that the presented protocol will allow research groups to independently design their own effective assays for testing for polymorphisms of interest.
RESUMO
The effectiveness of ethylmethylhydroxypyridine succinate (EMHPS) in acute alcohol intoxication was tested in a study on SPF male outbred ICR mice. Ethanol (concentration 40%) was administered to animals once intraperitoneally at a dose of 4 g/kg. Control animals were injected with saline in an equivalent volume. In 15 min after the administration of alcohol, the animals were injected intravenously or intramuscularly with EMHPS at a dose of 50 or 100 mg/kg or with saline via the same route in an equivalent volume. Animal behavior was tested 3 and 24 h later after administration of the substances. After 3 and 24 h, mice in the pathological control groups developed semiptosis, the gait and the turning over reflex were impaired, the strength of the hind limbs decreased and the distance between the hind limbs increased when landing; in the open-field test, the latency of the first movement increased, and the number of rearing postures decreased. Intravenous and intramuscular administration of EMHPS in doses of 50 and 100 mg/kg had a pronounced antitoxic and neuroprotective effect in acute alcohol intoxication: all studied parameters did not differ significantly from the control.

We examined the effects of elevated temperatures and biocides on survivability of food isolates of Cronobacter spp. (C. sakazakii) and concomitant enterobacteriaceae obtained in microbiological control of infant nutrition products. Increased resistance of certain strains of Cronobacter, Enterobacter cloacae, and Pantoea spp. to thermal processing was revealed. Salmonella, Pantoea, and Cronobacter bacteria were least sensitive to antimicrobial action of chlorine-containing agents. The above properties varied in the strains of the same species. Specifically, only two of three examined isolates of Cronobacter spp. demonstrated lower sensitivity to heat in comparison with the enterobacterial test-cultures of other species.

The chemical structure of piperidine has a unique ability to combine with other molecular fragments. This fact makes it possible to actively use it as an effective basis for the creation of new drug-like substances. Thus, the aim of the current investigation was to study the acute toxicity, local anesthetic potency, and antiarrhythmic activity of the two new synthesized piperidine derivatives under laboratory codes LAS-286 and LAS-294 (local anesthetic substances). The Bulbring & Wajda animal model and method of determining the nociception threshold during electrical stimulation was used to investigate the action of the substance during infiltration anesthesia. An antiarrhythmic activity was observed by the aconitine-induced rat arrhythmia model. Additionally, these compounds were studied in relation to molecular docking to delineate the structure-activity relationships. The tested piperidine derivatives had a low toxicity in the subcutaneous and intravenous administration routes. The experimental results showed a higher prolonged and pronounced local anesthetic activity for LAS-286 at a 0.5% concentration, compared to the reference preparations. The low dosage of 0.1 mg/kg of LAS-294 demonstrated a pronounced preventive antiarrhythmic effect in 90% of cases on the development of mixed arrhythmia, caused by aconitine. The results of molecular docking confirmed a higher binding affinity of the tested piperidines with the Nav1.4 and Nav1.5 macromolecules. The results of the present study are very promising, because these piperidines have shown a high biological activity, which can suggest a potential therapeutic application in the future.

The Abrau sprat (tyulka or sardelka) Clupeonella abrau (Maliatsky, 1930) is an endemic fish of the Lake Abrau (Krasnodar Krai, Russia). The full C. abrau mitochondrial genome (16 650 bp) showed a gene arrangement conserved in Clupeidae and 98.8% similarity with the mitochondrial genome of the related species Black and Caspian Sea sprat C. cultriventris from the Black Sea. The COX1 gene sequence was additionally studied in a museum specimen collected in the Lake Abrau in 1938. Variability in modern Abrau sprat COX1 gene locus was estimated at approximately 0.15%, the difference between C. abrau and C. cultriventris was 1.2%, and the difference between the museum and modern C. abrau specimens from the Lake Abrau was 0.92%. The study confirmed that the Abrau sprat is present in the fish community and is capable of reproducing in the lake. Various scenarios were proposed to explain colonization of the Lake Abrau by C. abrau.

The pathogenesis of immunoinflammatory rheumatic diseases (IRDs) is based on chronic inflammation, one of the key mechanisms of which may be abnormal activation of macrophages, leading to further disruption of the immune system. OBJECTIVE: . The objective of this study was to evaluate the proinflammatory activation of circulating monocytes in patients with IRDs. MATERIALS AND METHODS: . The study involved 149 participants (53 patients with rheumatoid arthritis (RA), 45 patients with systemic lupus erythematosus (SLE), 34 patients with systemic scleroderma (SSc), and 17 participants without IRDs) 30 to 65 years old. Basal and lipopolysaccharide (LPS)-stimulated secretion of monocytes was studied in a primary culture of monocytes obtained from blood by immunomagnetic separation. Quantitative assessment of the cytokines tumor necrosis factor α (TNF-α), interleukin 1ß (IL-1ß), as well as the chemokine monocyte chemoattractant protein-1 (MCP-1) was carried out in the culture fluid by ELISA. Proinflammatory activation of monocytes was calculated as the ratio of LPS-stimulated and basal secretions. RESULTS: . It was shown that the basal secretion of all studied cytokines was significantly increased in all groups of patients with IRDs, except for the secretion of IL-1ß in the SLE group, compared to the control. LPS-stimulated secretion of TNF-α was increased and MCP-1 was decreased in patients with IRDs compared to the control group; LPS-stimulated IL-1ß secretion only in the SSc group significantly differed from the control group. In the RA group, monocyte activation was reduced for all cytokines compared to the control; in the SLE group, for TNF-α and MCP-1; in the SSc group, for MCP-1. CONCLUSIONS: . The decrease in proinflammatory activation of monocytes in patients with IRDs is due to a high level of basal secretion of cytokines, which can lead to disruption of the adequate immune response in these diseases and is an important link in the pathogenesis of chronic inflammation.

OBJECTIVE: Custom prescription helmets for plagiocephaly may be a significant financial burden for families, especially when not covered by insurance. This study aims to identify factors that influence the success of crowdsourcing campaigns for this therapy. DESIGN: GoFundMe campaigns were collected by searching terms such as "plagiocephaly" and "baby helmet." Two reviewers analyzed each campaign for variables, including demographic data, story elements, and photo characteristics. Univariate logistic regression was used to determine each variable's impact on success, defined as attaining ≥75% of a campaign goal and significance of p ≤ 0.05. RESULTS: Campaign data from 2011 to 2022 were analyzed. Initial search yielded 1464 campaigns; among these 413 met final inclusion criteria. On average, campaigns raised $2005 (range: $0-$7799) and requested $3151 (range: $160-$30,000). In total, 228 (54%) achieved success, 167 (40%) met their goal, and 35 (8%) raised no funds. A total of $828,256 was raised from the requested $1,301,317. The average reported age was six months (range: 2-17 m). Significant factors associated with success were military affiliation, providing multiple images, including a quoted cost, providing campaign updates, indicating a sense of urgency, diagnosis of torticollis, and mentioning possible complications without treatment. Raising additional funds for therapy, multiple helmets, and unrelated medical costs negatively impacted success. Racial disparities were observed between campaigns. Additionally, regional differences were noted between campaigns. CONCLUSIONS: Crowdsourcing can be a successful endeavor for some families experiencing financial hardships from helmet therapy. This study highlights current gaps within healthcare coverage for helmet treatment and identifies various factors influencing crowdfunding campaigns.
RESUMO
OBJECTIVE: To analyze bone tissue damage at different stages of disease (El Oakley classification), treatment options for each clinical situation and results after each approach. MATERIAL AND METHODS: There were 45 patients with wound complications after cardiac surgery between October 2022 and September 2023. Thirty-eight (84.4%) patients underwent CABG, 7 (15.6%) patients - heart valve or aortic surgery. Mean age of patients was 68.1±10.3 years. There were 35 men (77.8%) and 10 women (22.2%). The first type was found in 11 (24.5%) patients, type 2-3 - 19 (42.2%), type 4 - 4 (8.8%), type 5 - 11 (24.5%) patients. RESULTS: Systemic inflammatory response syndrome was observed in 7 (36.8%) persons of the 1st group, 14 (73.7%) ones of the 2nd group, 4 (100%) patients of the 3rd group and 2 (18.2%) patients of the 4th group. C-reactive protein and procalcitonin increased in all patients with the highest values in groups 2 and 3. Redo soft tissue inflammation occurred in all groups after treatment. Mean incidence was 25%. Two (10.5%) patients died in the 2nd group and 1 (25%) patient in the 3rd group. CONCLUSION: The modern classification of sternomediastinitis does not fully characterize severity of disease in a particular patient. Simultaneous debridement with wound closure demonstrates acceptable mortality (within 10%). The highest mortality rate was observed in patients with diffuse lesions of the sternum. Less aggressive treatment approaches are possible for stable anterior chest wall.

A number of pharmacological drugs have side effects that contribute to the occurrence of atrial fibrillation, the most common type of cardiac rhythm disorders. The clinical use of antihistamines is widespread; however, information regarding their anti- and/or proarrhythmic effects is contradictory. In this work, we studied the effects and mechanisms of the potential proarrhythmic action of the first-generation antihistamine chloropyramine (Suprastin) in the atrial myocardium and pulmonary vein (PV) myocardial tissue. In PV, chloropyramine caused depolarization of the resting potential and led to reduction of excitation wave conduction. These effects are likely due to suppression of the inward rectifier potassium current (IK1). In presence of epinephrine, chloropyramine induced spontaneous automaticity in the PV and could not be suppressed by atrial pacing. Chloropyramine change functional characteristics of PV and contribute to occurrence of atrial fibrillation. It should be noted that chloropyramine does not provoke atrial tachyarrhythmias, but create conditions for their occurrence during physical exercise and sympathetic stimulation.

A fundamentally new software method for automated measurement of morphometric parameters of computed tomographic image of the human radius has been designed. The parameters obtained by manual morphometry of computed tomograms using the RadiAnt DICOM Viewer software were compared with the results of the software product developed by us. The relative error in the measurement of morphometric parameters was about 10%. In the future, the presented software method of automated determination of morphometric parameters of the bone will enable modeling of individual prosthesis of the head of the radius based on the results of computed tomograms with consideration of the structural features of the human radius.
