The global coronavirus pandemic has made significant adjustments to the higher education system, inducing the search for optimal teaching methods that will optimize the educational process for all its applicants, and will enable to perform an adequate assessment of the level of knowledge of students.Purpose of work. Determine the best methods of online teaching material for students, depending on their characteristics of perception of information, as well as provide an effective way to control knowledge.Material and methods. During the quarantine period and online training, the Google Meet platform was used to conduct online workshops and seminars. Depending on whether the information channel of information perception prevailed among the majority of students in the group, an individual approach to presenting information with different types of clarity was used. Evaluation of the effectiveness of various methods of presenting the material was carried out through intermediate and current control of knowledge, as well as oral questioning of students at the end of the semester.Results. The highest productivity of information perception was found when combining different teaching methods during one lesson, when students take turns using a sound, visual analyzer, and also holding pre-printed materials in their hands. The use of short scenarios of simulation medicine, when there is an opportunity to improve communicative competence, significantly increases the activity of students during the lesson, manifests itself in the number of \"raised hands\" and comments in the chat. The ingenuity and perseverance of the teacher makes it possible to objectively assess the knowledge of students, despite the obvious difficulties, online learning brings. Conclusion. During quarantine and distance learning, the most effective are the methods of combined presentation of the material, when students have the opportunity to use all channels of information perception.","PeriodicalId":9270,"journal":{"name":"Bukovinian Medical Herald","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75873473","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}

Ischemic atherothrombotic stroke (IATS) – multifactorial disease caused by a combination of genetic and environmental factors. Despite numerous studies of the pathogenetic component of ischemic stroke, there are no preclinical biomarkers that could support the study of molecular and physiological processes that lead to stroke. That's why a strategy for studying the pathogenesis of stroke is to start by identifying the genes associated with stroke. In particular, with ischemic stroke, an abnormal expression of MALAT1 plays an important role in such processes as angiogenesis, apoptosis, and inflammation. However, the study of the connection of the SNP variant of the MALAT1 with an IATS is few and not carried out in the Ukrainian population.The aim of this study was to investigate the possible association of rs4102217-polymorphism of the MALAT1 gene with ischemic stroke in individuals with normal and high blood pressure. Materials and methods. Venous blood of 200 patients with IATS was used for the study; the control group consisted of 234 practically healthy donors. To determine the SNP of rs4102217 MALAT1 was used polymerase chain reaction (Real-Time PCR). SPSS program (version 17.0, IBM, USA) was used for most statistical analyses. Results. It was found that the ratio of GG, GC and CC genotypes among the persons of the control group that had an increased AP - 84.9%, 13.7% and 1.4% respectively, and in the subgroup of persons from the main group with high blood pressure - 62,7%, 30.0%, 7.3% respectively. By applying χ2 – Pearson criterion was established a statistically significant difference in the distribution of genotypes between the comparative groups (χ2 - 12,015; P - 0,002). The results of logistic regression analysis showed statistically significant associations of IATS polymorphism in three models. So, the risk of development of IATS increases 2,97 times for patients with arterial hypertension, who are carriers of the C-allele (ORadj = 2,97; 95% CI = 1,286-6,785; Padj = 0,011 - for a dominant model). Conclusions. There is a link between the rs4102217-polymorphism of the MALAT1 gene and the development of IATI in people with normal and high blood pressure.","PeriodicalId":9270,"journal":{"name":"Bukovinian Medical Herald","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89844711","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. The study was performed on the basis of the Chernivtsi Regional Clinical Oncology Centre and the Oncology Clinic of Bukovinian State Medical University and covered observation materials of 50 patients with intra-abdominal neoplasms. Among them, 35 individualsforming the main group were obese (body mass index ≥30), the rest formed the comparison group. Comorbidity index, risk complication ratio, confidence intervals, Fisher (P) and χ2 coefficients were calculated according to Yates and Pearson. Results. In the comparison group, comorbidities were detected in only 6 patients (40.0%), in the main group, comorbidities were detected in all patients. The value of the comorbidity index in the main group was 11.23±0.98 against 6.37±0.72 (P=0.005). The risk of complications increases significantly in the presence of obesity (OR+ 2.49, min-1.29, max-4.80). The term of hospitalization increases slightly (22.36±3.14 in the main group, against 16.73±2.50 in the comparison group, P=0.18). Conclusions. In patients with malignant neoplasms of the abdominal cavity, the risk of postoperative complications is 1.29-6.96 times higher than in the absence of obesity. The presence of obesity is a significant factor in aggravating the condition, prolongs the period of hospitalization of patients with malignant neoplasms, creates additional challenges for the oncologist.","PeriodicalId":9270,"journal":{"name":"Bukovinian Medical Herald","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90152943","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 aim of this paper was to determine the structural and functional condition of liver and gallbladder (GB) in patients with hemorrhagic vasculitis. Materials and methods. We retrospectively analyzed data of 75 patients (57% females and 43% males, mean age 47.7±4.3 years) and estimated the structural and functional condition of their liver and GB (total bilirubin, transaminases, gamma-glutamyltranspeptydase (GGTP), alkaline phosphatase). The digital data was statistically processed and represented as M±m. Correlations were estimated according to Pearson (r). Data was considered significant if р<0.05. Results. It was revealed that sonographic signs of liver affection were present in 73.9% of patients with hemorrhagic vasculitis; sonographic signs of GB affection – in 61.3%. It is worth saying that these changes were mentioned in the diagnosis of 3.9% of patients only, which is a sign of insufficient attention of doctors to these changes. The mean values of routine laboratory markers of liver affection were in the normal range. We revealed hypobilirubinemia in 46.5% of patients, which can testify the frequent presence of oxidative stress.

The establishment and substantiation of biostatistical trends in the state of mortality of the population of Ukraine due to diseases of the circulatory system (I00-I99) in the context of the place of residence of the deceased for the period 2009-2019.Material and methods. An epidemiological, one-time, continuous, prospective scientific study was carried out using statistical data of the State Statistics Service of Ukraine and the Center for Medical Statistics of the Ministry of Health of Ukraine for the period 2009-2019, where the author performed the compilation and processing in spreadsheets of Microsoft Office Еxcel (2019). Retrospective, biostatistical, mathematical, abstract and graphic research methods are used, as well as methods of copying, deductive awareness, structural and logical analysis taking into account the principles of systematicity.Results and discussion. The obtained results indicate that mortality due to DCS (I00-I99), during the studied period (2009-2019), is dominant in the overall mortality structure of the population of Ukraine, where ischemic heart disease (I20, I24-I25) ranks first in terms of mortality, especially among the inhabitants of rural areas of the country, while the following rankings: second, third, fourth, consistently and intransigently share cerebrovascular disease (I60-I69), myocardial infarction (I21-I24) and hypertension (I10-I15), which are dominant in the inhabitants of urban areas.Conclusions. Given the excessive and direct burden of DCS mortality on the quantitative expression of the country's population and its negative impact on people's quality of life, as well as the state of public health, socio-economic well-being and resource provision of society, the state of Ukraine is required to make decisive and effective priority adequate management decisions of preventive content, to minimize cardiovascular pathology (I00-I99) in the context of \"European guidelines for the prevention of cardiovascular disease in clinical practice\" (2016).","PeriodicalId":9270,"journal":{"name":"Bukovinian Medical Herald","volume":"348 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75946339","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 analysis of the obtained results was carried out by the package \"STATISTICA 5.5\" (using nonparametric methods).Results. When studying the Echo-EG indices, we detected no interhemispheric asymmetry in any case. The distance to the terminal complex on the right and left was more significant in girls than boys in almost all age categories, except for the three-year-old age, here the opposite trend was found. The analysis of M-echo by age revealed a physiological increase in the index at the age of two in boys and girls. Subsequently, the distance to M-echo gradually decreases with age in boys. In girls, this index maximally reduced at the years 3 of age. Comparison of the M-echo width by age revealed a physiological increase in the index at the age of two years in both sexes with a subsequent decrease until the age of five. In all examined children, the shape of the median complex was in the form of peaks with a narrow, clear base, with one apex. Comparison by age parameters revealed a stable value of the cerebral cortex index in all age groups. In all examined children, the “pulsation” index did not exceed 20%.Conclusions.

Classical regression methods are not very informative in determining the mutual burden of ReA and chronic pyelonephritis (CP), as well as the primacy of the disease.Objective - to investigate the possible relationship between ReA and CP in order to establish early criteria for predicting the development of CP on the background of ReA on the indicators of connective tissue metabolism. Material and methods. 113 patients were examined, which were divided into two groups: the first group - patients with urogenic ReA, activity I-III. FTS I-III st. (n = 65); the second group - patients with urogenic ReA and CKD I-II: pyelonephritis in the acute phase (n = 48). The control group consisted of 20 healthy individuals. The average duration of the disease of the examined patients was 24.4 ± 4.7 months. The mean age of patients was 32.5 ± 1.2 years. DataMining clustering and classification methods were used to process the obtained research results.Results. As a result of clustering methods (k-means and fuzzy clustering), the same results of cluster membership were obtained. In particular, ReA disease was correctly diagnosed in 48 cases, which is 74% of all diagnosed, 17 people (26%) were assigned to cluster \"2\". There is also a mismatch in the second cluster. In particular, out of 32 people diagnosed with ReA + CP, according to mathematical calculations, 28 people (88%) got into this cluster. Four patients (13%) were assigned to cluster \"1\" – to the group of persons in whom only one ReA disease should be diagnosed. This indicates that the boundary between the ReA and ReA + CP clusters are somewhat blurred. And this is the basis for establishing the fact that ReA disease can gradually lead to CP.Conclusions. Using DataMining clustering methods the greatest significance was defined in the diagnostic algorithm of ReA progression of such indicators as free oxyproline (FOP), protein-bound oxyproline (PBOP), the degree of collagenolytic activity (CLA) (intensity of azocol lysis), which showed a direct dependence on the degree of activity of the inflammatory process.
