The aim of the present study was to find out a link between the epidemiological parameters of tuberculosis and the suicide rates in Russia. Materials and Methods . Trends in tuberculosis incidence/mortality and the suicide rates from 1980 to 2015 were analyzed using a time series analysis in order to asses bivariate relationship between the time series. Results . The results of analysis indicate the presence of a statistically significant association between tuberculosis mortality and suicide rates for men at lag zero (r=0.71: SE=0.169). The association between tuberculosis mortality and suicide rates for women was also positive, but statistically not significant (r=0.26: SE=0.169). Conclusions . The results of this study suggest positive aggregate-level relationship between tuberculosis mortality and suicide rates in men. This study indirectly supports the hypothesis that tuberculosis mortality can be considered an indicator of psychosocial distress.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"15 1","pages":"599-611"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80936742","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 a conceptual model the main information blocks are “Hygienic Evaluation of the Working Conditions and of Workload” (for prior evaluation of occupational risk) and “Evaluation of Health Condition” (for posterior evaluation of occupational risk). The task of the first block was evaluation of exposure doses of such factors as thermal stress of the environment, local and total vibration, noise, and also evaluation of the extent of the workload by parameters of severity and tension of the working process. The health condition was evaluated by four blocks: parameters of the functional condition of an organism, presence of occupational diseases, diseased conditions with temporary disability, and evidence of accelerated ageing by parameters of biological age. Results and Conclusions . Results are presented on the basis of in-depth analysis of intensive influence of industrial factors in accordance with domestic and ISO standards. Etiogenous analysis of occupational risk for the main stress factors and integral evaluation by the index of occupational diseases were conducted. The index takes into account categories of risk and severity of occupational diseases with respective partial indices for the leading unfavorable industrial factors. This enabled adequate evaluation of damage to health induced by occupational industrial factors of different intensity. Comparison of hygienic and medico-biological parameters of evaluation of occupational risk on the basis of etiogenous analysis showed the probability for quantitative evaluation of multi-factor intensive influences and for development of effective prophylactic measures on their basis.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"141 1","pages":"575-585"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73283469","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 urgency of the problem, peculiarities of the clinical course and treatment of tuberculosis, the principles of antiretroviral therapy in the combination of tuberculosis and HIV infection are considered. It has been established that long-term chronic (или “long term” или “chronic”) tuberculosis intoxication, as well as aggressive antituberculosis therapy, lead to disruption of metabolic processes, hypercatabolism, intoxication, and development of hypercoagulable syndrome. At the same time, data is provided on the toxic effects of antiretroviral therapy. Treatment of adverse reactions begins with detoxification and antihistamine therapy followed by the addition of vitamin therapy, antioxidants, antihypoxants, hepatoprotectors, anabolic agents, and enterosorbents. Various methods of pathogenetic therapy are of great interest, including extracorporal hemocorrection (plasmapheresis) and intravenous laser irradiation of blood (ILIB). Plasmapheresis (PA) allows the effective and short time normalization of homeostasis indices as well as reduction or elimination of intoxication effects, toxic and allergic reactions, hence increasing the effectiveness of basic therapy. Course of PA in patients with common forms of tuberculosis (3-5 procedures, with an interval of 2-3 days, removal of 20-25% of the volume of circulating plasma and replacement with crystalloid solutions in combination with hydroxyethyl starches) allows the elimination of symptoms of intoxication, increases tolerance of the organism to chemotherapy, and suppresses undesirable side effects. The method of quantum therapy (ILIB) is based on the effect of quantum energy on blood directly in the vascular bed. As the result photo biological influence of ILIB, all body systems are activated to correct the existing disorders. This is manifested to a great extent in tissues suffering from oxygen deficiency, since it is in these areas the metabolism increases and the processes of tissue reparation are activated. ILID helps for activation of white blood cell function, phagocytosis, synthesis of antibodies, interferon, and in general, improves the immune status.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"24 1","pages":"655-668"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89771475","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}

Identification of possible risk factors, assessment of their information value, and compilation of a prognostic table for assessing the risk of healthcare associated infections in puerperas. Materials and Methods . Experimental and control groups were formed from among the puerperas. The experimental group included 147 women who developed purulent-septic infection within 30 days after delivery. The control group was formed by the mechanical selection of each 50th labor and delivery record for the aforementioned period and included 300 subjects. Possible risk factors were divided into groups: social factors, factors related to the state of woman's health, factors associated with the peculiarities of the pregnancy course, factors associated with the peculiarities of the labor course, factors associated with the postpartum period. Results . During the study, the following risk factors were identified: unregistered marriage, prenatal hospitalization to the Department of Pathology of Pregnancy for more than 1 bed-day, first labor, uncoordinated contractions, amniotomy, episiotomy, hysterocervicorrhexis, staying in the ward of separate residence in the postpartum period. Based on the sum of the values of prognostic indices, calculated for each risk factor, three prognostic groups were formed: high, average and low risk. Forecasting of the risk for healthcare associated infection development in a patient is carried out by simple arithmetic addition of prognostic indices. Conclusion . To prevent healthcare associated infections, it is recommended: to carry out bacteriological examination of an afterbirth and prescribing preventive course of antibiotics to puerperas of the high risk group in the postpartum period; to specify that a woman is at high or average risk, if any, in the discharge documentation to inform the Women's Health Department. The information on belonging of the puerperas to a particular risk group can be used by the hospital epidemiologist when carrying out operational and retrospective analysis.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"22 1","pages":"565-574"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83829488","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, a lot of drugs alter the activity of the transporter. It can lead to drug-drug interactions during polypharmacy. Fabomotizole (afobazol) is a Russian anxiolytic drug with neuroprotective activity, applied over a wide range of indications. The drug belongs to a potential substrate of Pgp according to its chemical structure. Aim . The aim of the study was to assess belonging of fabomotizole to Pgp substrates. Materials and Methods . The work was performed on 12 male Chinchilla rabbits. The belonging of fabomotizole to Pgp substrates was evaluated by comparing pharmacokinetic parameters of the test-substance after course administration of known transporter inducers and inhibitors – rifampicin and verapamil respectively. Fabomotizole was administered orally as a single dose of 3.8 mg/kg b.w. and blood was taken from the ear vein after 5, 10, 15, 20, 30, 60, 90, 120 and 240 min followed by it's pharmacokinetic analysis by HPLC. Pharmacokinetic parameters of fabomotizole were manually calculated by a model-independent method. The animals were then divided into 2 groups of 6 rabbits each: the 1st group received verapamil at a dose 20 mg/kg b.w. 3 times a day for 14 days, the 2nd – rifampicin in a similar course and dose. After the administration of Pgp modulators the pharmacokinetics of fabomotizole were re-analyzed. Results . It was found that only the absorption coefficient of fabomotizole in the rifampicin series was significantly reduced by 1.27 times as compared to the parameter of intact animals (90% CI 0.66-0.94, p=0.04322). However, this change was not clinically significant, because 90% CI overlapped the range of 0.80-1.25, noted by FDA. The remaining pharmacokinetic parameters of Pgp marker substrate were not significantly changed in any series. This is evidence that fabomotizole is not a Pgp substrate. The insignificant participation of Pgp in fabomotizole pharmacokinetics testifies that the drug can be administered together with drug-modulators of transporter activity without dose correction. Conclusion . In vivo experiment on Chinchilla rabbits showed that fabomotizole is not a substrate of P-glycoprotein.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"17 1","pages":"538-550"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84371590","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}

Currently, the goals of patients’ treatment with rectal cancer are to cure, to minimize the risk of local recurrence, preserve the normal course of intestine, to optimize it's function and to ensure quality of life. For a long time, the standard surgical treatment of patients with low rectal cancer was abdominoperineal extirpation, but recently sphincterosafing operations have seen a widespread introduction in surgical practice. However, functional results after these types of operations don't always meet the expectations of surgeons and patients. In the postoperative period, patients often develop a syndrome of low anterior resection, characterized by frequent bowel movements, repeated, prolonged and incomplete evacuation of bowel and the imperative urge to defecate. The manifestation of this syndrome can significantly impair the quality of patient's life and reduce to nothing the efforts of the surgeon to preserve the sphincter of the rectum. For surgical correction of low anterior resection syndrome, various types of colonic reservoir anastomoses have been proposed. The purpose of formation of colonic reservoirs is to increase the cumulative function of intestine. However, the existing methods have several disadvantages related to technical complications and the risk of developing evacuation dysfunction, which is the reason for search the new ways of optimization of anastomoses when performing sphincterotomy operations for cancer of the rectum.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"190 1","pages":"642-654"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74177111","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}

This pathology continues to be one of the important problems of modern medicine. It is known that thrombophilia can play a significant role in the etiology of spontaneous reproductive losses. However, the pathogenesis of recurrent spontaneous loss of pregnancy in the presence of maternal thrombophilia is not fully understood. Aim . To identify the features of the histological structure of trophoblasts and chorionic villi in the first trimester of pregnancy in women with thrombophilia and recurrent pregnancy loss, with careful exclusion of other possible causes of fetal loss syndrome. Material and Methods . Histological examination of 49 chorion tissue samples from 24 patients with thrombophilia and recurrent pregnancy loss in the first trimester (study group) was performed. The controls were samples of chorion tissue taken during artificial abortion in 33 healthy women who had a history of 2 or more spontaneous labor without significant complications. Thrombophilia diagnosis and hemostasis system state evaluation was performed for all patients on the basis of analysis of 30 parameters according to standard methods. All studies were conducted at the Regional clinical hospital № 8 in Ryazan as well as the scientific and clinical center of hematology, oncology and immunology of the Ryazan State Medical University named after academician I.P. Pavlov of Health Ministry of the Russian Federation. Statistical processing of the obtained results was carried out with the help of computer program package Statistica (version 10). Results . Significant differences in the histological structure of trophoblast and chorionic villi in the studied women were revealed, in comparison with those in the control group. It is proved that the presence of thrombophilia negatively affects the process of embryogenesis and contributes to a significant reduction in the area of the chorionic villus vessels in the first trimester of pregnancy. Conclusion . It is proved that the presence of thrombophilia has a negative effect on the process of embryogenesis and significantly reduces the vascular area of chorionic villi that can probably play a significant role in the pathogenesis of recurrent pregnancy loss.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"153 1","pages":"621-641"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79207877","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}

Characteristics of microvessels are of high diagnostic and prognostic significance, however, the results of previous studies are controversial. The aim of the work is to evaluate the features of angiogenesis in diffuse gliomas on the basis of determining the qualitative and quantitative microvascular characteristics. Also important is their relationship with the histological type of tumor. Microvascular density (μm-1), total vascular area (%), total lumen area (%) and the mean diameter of microvessels (μm) were measured and calculated in diffuse brain gliomas (n=76) using GFAP-negative status of endothelium in the presence of exclusively GFAP-positive tumor cells.
