A hypothesis on the main role of factors of psychosocial and psychological distress in the formation of gender differences in mortality in the post-Soviet period is proposed. Aim of the research. To identify the characteristics and main causes of changes in gender trends and indicators of sexual dimorphism in mortality of the population of the Irkutsk region in the post-Soviet period. Methods. Statistical materials were obtained from the databases of the Federal State Statistic Service of the Russian Federation and from the Demographic Yearbooks of Russia. To establish the gender characteristics of irrevocable demographic losses, we analyzed the values of the male excess mortality index. It is defined as the ratio of the mortality rate of men to the corresponding indicator for women. We established the close connection between changes in the male supermortality index and the level of psychological distress of the population. The last index was determined by the suicide rate. Results. During the 31-year period (1987–2017), the highest values of the male mortality index were observed in 1993– 1995 and in 2001–2005. An indicator of the frequency of suicides is proposed and applied as a specific socio-demographic criterion for the influence of the factor of psychological distress on the socio-demographic status of the population. The dependence of the male supermortality index on the level of psychological distress for the period from 1991 to 2017 is estimated. A strong positive relationship between these indicators was identified (r = 0.792; p < 0.0001). Conclusion. Changes in the indicator of male supermortality largely depend on changes in the level of psychological distress. The indicator of sexual dimorphism of mortality (the index of male supermortality) can be used as an important indicator of pronounced changes in psychosocial and psychological distress and, accordingly, the quality of life of a society.","PeriodicalId":6986,"journal":{"name":"Acta Biomedica Scientifica (East Siberian Biomedical Journal)","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82796913","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}

An infant brain damage is an extremely urgent problem, this pathology is difficult to prevent, and subsequently it manifests itself with a variety of neurological consequences. Various mechanisms are involved in neurodamage; cytokines, as well as genes that control their activity, are under a great concern today. However, there is little data about their role as predictors of the brain damage among children after hypoxia. Aim of the research. To identify the frequency of cytokine gene polymorphism: interleukin (IL)-1β(C-511T), IL-1β(C3953T), IL-4(C589T), IL-6(C174G), IL-10(C819T), IL-10(G1082A) among newborns with hypoxic events. Materials and methods. The study involved 128 full-term newborn patients with hypoxic events: the first group (n = 48) included newborns who experienced chronic intrauterine hypoxia (CVH), the second group (n = 80) included newborns born in asphyxiation. Control group (52) included babies born without asphyxia and not suffering from CVH. A retrospective analysis of case-records was carried out. The material for molecular genetic analysis was DNA samples isolated from umbilical cord blood leukocytes using DNA Express Blood reagents (Scientific and Production Company LITECH, Moscow). Results. Compared to the control group (p = 0.03) children born in asphyxia had their T allele IL-1β (C-511T) prevailed. The group of newborn who had CVH had their TT genotype (p = 0.04) and the T IL-1β allele (C-511T) (p = 0.01) prevailed compared to the control group. In the same study group while studying the polymorphism of the IL-1β gene, the T allele (p = 0.03) at the point C3953T prevailed, in contrast to the control group. Conclusion. Due to the fact that cytokines are part of a reaction cascade leading to the secondary brain damage, under the action of hypoxia, it was found that among newborns undergoing asphyxia and chronic intrauterine hypoxia the increased frequencies of carriage of IL-1β-511TT and IL-1β-3953TT genotypes, and IL-1β-511T and IL-1β-3953T alleles increase the risk of neurodamage.","PeriodicalId":6986,"journal":{"name":"Acta Biomedica Scientifica (East Siberian Biomedical Journal)","volume":"92 7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87750301","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}

Coronary heart disease is the leading cause of death in the Russian Federation, causing social and economic damage to the state. Previously published studies showed the association of rs1800470 polymorphism of the gene of the transforming growth factor-β1 (TGF-β1) with the risk of developing coronary artery disease due to more severe atherosclerotic lesions of the coronary arteries. Aim of the research. To study the association of single-nucleotide polymorphism rs1800470 of the TGF-β1 gene with the rate of progression of atherosclerotic coronary artery lesion. Material and methods. The study included 89 men with myocardial infarction, a Caucasian race under the age of 65 years (51 ± 7.9). Genomic DNA was isolated from venous blood by the phenol-chloroform method. The rs1800470 polymorphism of the TGF-β1 gene was tested using real-time polymerase chain reaction (PCR) (TaqMan probes, AB 7900HT). Assessment of the severity of coronary lesion was carried out initially according to the standard polyprojection coronary angiography protocol with the Gensini score calculated, as well as in dynamics after 40.7 ± 29.7 months (from 5 to 103 months). Results. Carrier of the rs1800470 allele A of the TGF-β1 gene is an independent risk factor for coronary heart disease and is associated with a more aggressive course of coronary atherosclerosis in men: a 20 % worsening of the Gensini score was observed after 7 months (p = 0.013), and by 30 % after 5 months (p = 0.003) from the initial coronary angiography. In addition, the homozygous genotype AA rs1800470 of the TGF-β1 gene is associated with the development of late stent restenoses in this group of patients after 12 months of observation (p = 0.002). Conclusion. Identification of carriers of the rs1800470 allele A of the TGF-β1 gene can help identify patients at risk for more rapid progression of coronary artery atherosclerosis in order to conduct angiographic control in the early period – 6 months from the initial percutaneous coronary intervention.","PeriodicalId":6986,"journal":{"name":"Acta Biomedica Scientifica (East Siberian Biomedical Journal)","volume":"1996 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82471246","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}

In addition to an increase in mortality, bleeding can cause the development of other postoperative complications, which lead to disability of patients and to a decrease in the quality of life in all age groups. Most perioperative bleeding are caused by technical errors. This article reviews the problem of perioperative bleeding from the point of view of impaired coagulation capabilities of the body. The main etiopathogenetic features of hemostasis during the development of this complication are considered. The analysis of postoperative complications, which were directly or indirectly caused by bleeding during or after surgery, is presented. The prevalence of these complications in various areas of surgery has been demonstrated. More detailed study of the hemostasis system and the identification of predictors of hemostasis difficulties before the surgery may cause an improvement in the results of surgical treatment and reduce the number of postoperative complications and the duration of hospital stay. Accordingly, this will lead to a decrease in the cost of treatment and an increase in patient satisfaction with the medical care. In connection with the above, there is a great interest among surgeons and anesthesiologists in preventing the development of perioperative bleeding.","PeriodicalId":6986,"journal":{"name":"Acta Biomedica Scientifica (East Siberian Biomedical Journal)","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90460433","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}

Difficulties in performing this surgery are mainly associated with the anatomical features of the parathyroid glands, in particular with the variability of their number and topographic anatomy. Ectopic parathyroid glands are one of the most common causes of persistence or recurrence of secondary hyperparathyroidism after surgery. One of the common variants of ectopia is the localization of the parathyroid gland in the anterior-superior mediastinum. The article discusses the features of surgical treatment of secondary hyperparathyroidism in patients with end-stage chronic kidney disease with this ectopia. A new method of treating hyperparathyroidism in patients with an atypical location of the parathyroid gland in the anterior-superior mediastinum is presented. This method is characterized by low invasiveness of access, ease of implementation without using special equipment and instruments. The proposed method was used in the treatment of a patient with secondary hyperparathyroidism due to chronic renal failure as a result of chronic glomerulonephritis. The duration of hemodialysis at the time of the surgery was more than 17 years. In the presented clinical case, ectopia of one of the pathologically altered parathyroid glands in the anterior-superior mediastinum was found at the preoperative stage. As a method of surgical treatment, we carried out total parathyroidectomy with autotransplantation of a fragment of parathyroid tissue into the brachioradialis muscle. Thanks to this method, it was possible to remove the atypically located parathyroid gland from the cervicotomy access and to discharge the patient within the standard terms for a given volume of surgery.","PeriodicalId":6986,"journal":{"name":"Acta Biomedica Scientifica (East Siberian Biomedical Journal)","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77164850","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}

Sporadic multiple gland disease in primary hyperparathyroidism occurs in 7 to 33 % of cases. The absence of specific risk factors, low sensitivity of imaging methods, and low efficiency of bilateral neck exploration and intraoperative monitoring of parathyroid hormone indicate the complexity of the diagnosis and treatment of this disease’s form. Aim of the research. To analyze the results of surgical treatment of multiple lesions of the parathyroid gland in primary and secondary hyperparathyroidism. Methods. There was retrospective study, which included 100 observations of surgical treatment for primary and secondary hyperparathyroidism in the thoracic department of Irkutsk Regional Clinical Hospital from May 2018 to September 2019. The main point was to identify the frequency of surgical treatment outcomes in patients with multiple parathyroid lesions. As part of the study, potential predictors of multiple gland disease in primary hyperparathyroidism were analyzed. Results. Multiple gland disease in primary hyperparathyroidism occurs in 29 % of cases and causes persistence of the disease (p ≤ 0.01). Signs of multiple gland disease in primary hyperparathyroidism include the level of ionized calcium, parathyroid hormone (p ≤ 0.05), creatinine level and glomerular filtration rate (p ≤ 0.01). A negative result of intraoperative monitoring correlates with persistence of primary hyperparathyroidism in multiple lesions (χ2, p ≤ 0.05). Selective parathyroidectomy is associated with persistence of hyperparathyroidism in multiple lesions (χ2, p ≤ 0.05), while total parathyroidectomy is associated with remission of the disease (χ2, p ≤ 0.05). We did not find a statistically significant relationship between the results of surgical treatment for morphology of the parathyroid glands (χ2, p > 0.1). Conclusion. Multiple gland disease is the main cause of persistence of primary hyperparathyroidism. This form of the disease corresponds to lower levels of calcium, parathyroid hormone, and kidney function. Persistence factors have been established: removal of less than four parathyroid glands and a negative result of intraoperative monitoring of parathyroid hormone. Bilateral neck exploration does not reduce the incidence of disease persistence.","PeriodicalId":6986,"journal":{"name":"Acta Biomedica Scientifica (East Siberian Biomedical Journal)","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87527841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common chronic cerebrovascular pathology is dyscirculatory encephalopathy, in which a decrease in blood supply due to damage to brachiocephalic vessels leads to damage to brain substances and analyzers, including visual, with the possible development of severe damage in the form of ischemic optic neuropathy. Many studies have been devoted to the relationship between atherosclerotic damage to the neck vessels and ischemic damage to the visual organ, but little attention has been paid to the study of the functional activity of the altered visual analyzer in patients with dyscirculatory encephalopathy, and the results are scattered. Aim. To conduct a comparative analysis of changes in neurophysiological parameters of the brain and visual analyzer in patients with dyscirculatory encephalopathy and patients with a combination of dyscirculatory encephalopathy and ischemic optic neuropathy. Materials and methods. 34 patients with the 2nd stage of dyscirculatory encephalopathy were examined and divided into two groups based on the presence/absence of ischemic optic neuropathy of various prescription periods. All patients underwent ultrasound scanning of neck vessels, visual fields determination, electroretinography, visual evoked potentials, and electroencephalogram. Results. The results revealed changes in a number of indicators in the group of patients with a combination of two diseases: more pronounced atherosclerotic lesion of brachiocephalic vessels, a decrease in the amplitude and the alpharhythm prevalence index, a decrease in oscillatory potentials, a change in latency and amplitudes the visual analyzer according, lengthening of time indicators with a simultaneous decrease in amplitudes and depression of retinal sensitivity.

In the framework of this work, the acute toxicity of the hydrogel polyhexamethylene guanidine hydrochloride was studied in laboratory animals with intragastric administration. Materials and methods. The polyhexamethylene guanidine hydrochloride hydrogel was obtained by crosslinking the amino end groups with formaldehyde. An acute toxicity study was carried out (P 1.2.3156-13, GOST 32644-2014 and the Guidelines for conducting preclinical studies of drugs) in an experiment on outbred mice with a single addition of the test substance in different doses (1000, 3000, 5000, 8000 mg/kg) with fixing indicators (appearance, behavior, condition of the body hair coat, water and food consumption, excretion, body weight and its growth) during 14 days. After the animals were withdrawn from the experiment, autopsy, macroscopic evaluation and weighing of the internal organs were performed. The results showed that with the introduction of the test substance into the animal organism, death during the observation period (14 days) did not occur.
