Material and methods. We examined 116 patients aged 44-60 years who were admitted to the hospital with uncontrolled stage 2 arterial hypertension, 96 of them had mild and moderate COVID-19. The patients were divided into two groups: the first group up to 12 weeks after suffering COVID-19 and the second group after 12 weeks. The examination included echocardiography and ambulatory blood pressure (BP) monitoring. Results. In post-COVID-19 patients, the ratio of daytime to nighttime systolic BP was statistically significantly lower than in disease-free patients (p <0,001, p1 =0,015). There was a decrease in the daily BP index in the group 1 and group 2 (11.6±0.8% and 12.2±1.2%, respectively, p=0,001). Among patients after COVID-19, non-dippers were detected, more often in group 1 (9 people (17.6%) versus 2 people (4.4%) (x2=4.18, p=0.042). Conclusion. Arterial hypertension in patients who underwent mild and moderate COVID-19 was characterized by an insufficient decrease in systolic blood pressure at night, the presence of non-dippers with positive dynamics after 12 weeks from the onset of the infectious process.","PeriodicalId":354475,"journal":{"name":"Saratov Journal of Medical Scientific Research","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115111744","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. 57 patients with histologically verified diagnosis of ovarian EC were studied; morphologically, endometrioid cysts were divided into types conventionally designated as \"immature\", \"mature\" and \"old\". Inflammatory cells were counted in the EC wall. Results. In the tissues of the \"immature\" EC, the underlying fibrous layer is represented by loose connective tissue, with a small number of granulocytes, single siderophages. An increase in the number of granulocytes in the fibrous layer along the border of the EC tissue (/-/=17.10; p<0.001; \"young\" — 8566.0 \"mature\" — 9719.0), as well as an increase in the number of lymphocytes in the stroma of the endometrioid lining (/-/=38.03; p<0.001; \"young\" — 6579.0; \"mature\" -11156.5) leads to a gradual compaction of the fibrous layer, that is the onset of a stage of \"mature\" endometrioid cyst. Violation of the blood supply to heterotopia leads to depletion of the macrophage pool due to the polarization of macrophages with an increase in the number of siderophages, that adversely affects the state of endometrioid heterotopia in the form of a decrease in almost all cells types: lymphocytes ofthe endometrioid stroma lining (/-/=38.03; p<0.001; \"mature\" — 11156.5; \"old\" — 6574.5); neutrophils of the endometrioid stroma lining (H=13.25; p=0.001; \"mature\" — 9199.5; \"old\" — 6136.0), neutrophils ofthe underlying fibrous layer (/-/=17.10; p<0.001; \"mature\" — 9719.0; \"old\" — 6025.0).

Material and methods. A longitudinal study of the opinion of medical university students was conducted. By the method of questioning with the help of author's questionnaires (two types of questionnaires with 15 questions, adapted to the tasks of the research stages). At the 1st stage, students of those training courses were surveyed, after which it is possible to obtain admission to medical activities as specialists with secondary medical or secondary pharmaceutical education (n=634); at the 2nd stage — students of those training courses who had the opportunity to work on the basis of the received admission (n=586). Results. There was a significant increase in students' awareness of the possibility to implement medical practice as nursing professionals having obtained an admission (from 59.3% to 84.3% of respondents). There were revealed the dominant motives to receive an admission: to get working experience for further professional practice or for residency admission (52.2% and 56.1% out of 100 respondents at the first and second stages of the survey respectively), to apply/work out the acquired competencies in practice in real conditions (42.3% and 34.3% out of 100 respondents respectively). The refore some undergraduates were not prone to obtain an admission and that attitude was explained by the difficulty of combining studies and work (60.1 % out of 100 respondents). Conclusion.

Over the seven-year period of work in the RSM module (2014-2020) it was possible to increase the number of patients with ruptured cerebral aneurysms transferred from the regions for surgery by 52.2% (from 88 patients in 2014 to 134 in 2020) and reduce the time from the admission of patients with subarachnoid hemorrhage to the regional medical institutions to their transfer to the regional vascular center for 1 day (from 1,5±0,6 days in 2014 to 0,6±0,5 days in 2020). Conclusion. In the geographically long Krasnoyarsk Region, where it is impossible to perform neurosurgical operations in most district hospitals, RSM module helps to track patients with aneurysm ruptures in real time and transfer them to the regional vascular center for surgical treatment in a timely manner, before the re-rupture or development of angiospasm.","PeriodicalId":354475,"journal":{"name":"Saratov Journal of Medical Scientific Research","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122356792","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}

According to the compiled questionnaire, a survey was conducted of 150 social workers for a subjective assessment of health disorders, factors of conditions and nature of work. Results. In 2020, compared to 2019, the number of cases of temporary disability increased by 2.8 times, in 2021 — by 2.5 times; the number of missed days increased by almost 3 times, the largest number of cases of temporary disability in 2021 was registered in the group with 5-9 years of work experience (31 out of 128 cases; 24%). When interviewing social workers for the presence of their health disorders and affecting their ability to work, the most common symptoms were those of the respiratory system (56%), the musculoskeletal system and connective tissue (16%). It was revealed that the factors of the severity of the labor process correspond to the harmful class of working conditions of degree 3.1, the factors of intensity of the labor process — the harmful class of working conditions of degree 3.2.

The evaluation was performed on 222 DICOM series of patients computerized tomography with bones of cranium defects. Results. The indicators of sensitivity, specificity and accuracy were 95.3%, 85.5% and 79.4% respectively. A number of experiments were carried out with step-by-step sorting of three-dimensional models in order to find the reasons for the unsatisfactory skull reconstructing results. Incorrect detection of the skull defect most often occurred in the area of the facial skeleton. After excluding the series with artifacts, the average increase in metrics was 2.6%. Conclusion. Correct determination of the bone defect at the scull model (specificity) by the algorithm had the greatest impact on the surface accuracy. The maximum accuracy of the algorithm, which allows using the obtained surfaces without additional processing in a three-dimensional modeling environment, was achieved on series without the presence of artifacts during computed tomography (83.5%), as well as with defects that do not extend to the skull base (79.5%).","PeriodicalId":354475,"journal":{"name":"Saratov Journal of Medical Scientific Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130448218","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}
