We discuss a simple method for automatic recognition of pulmonary emphysema in three-dimensional computer tomography (CT) images. This technique allows one to quantify the disease progress, calculating some numerical characteristics, such as the percentage of the lung tissue affected, as well as visualizing its location and intensity histogram in the region of interest. An experiment on the test data shows that the recognition error is not higher than 7.5%.
Background: Numerous studies have shown an effect of rapidly spreading SARS-COV-2 on combined anxiety-depressive disorders and maladjustment syndrome occurrences. Objective: To determine the primary medical students’ reactive anxiety level and the final scores of their educational progress in distance learning during the SARS-COV-2 pandemic. Materials and Methods: The study involved 824 students at medical universities in Saratov and Moscow. The assessment of the reactive anxiety level was carried out according to the State-Trait Anxiety Inventory, STAI; the average score of students' academic performance was calculated according to the data of the technological platform "1C: Enterprise" version 8.4.1. The survey was completed during distance learning in May 2020. The quality of distance learning was compared to a similar score for 2019, when students were trained in a traditional way. Statistical analysis was conducted using Statistica 6.0. Results: It was shown the presence of moderately severe disorders among the primary medical students according to the average score of reactive anxiety (43.28 ± 12.85), that expressed more in females s (p<0.05), After distance learning, lasting 25% of the whole course, the overall performance score in theoretical knowledge did not change significantly (p>0.05) but the practical skills suffered much especially in time trend (p<0.05). Novelty: It was found that a high level of the reactive anxiety negatively affects the students' adaptive capabilities and the education quality. The specificity of programs at different faculties can determine the state of the students' psychological status. Findings:Timely transition to online classes during pandemics helps to preserve the students' mental well-being and the quality of the educational process. The duration of distance learning for a practical course should not exceed 25% of the whole course. Doi: 10.28991/esj-2021-SPER-07 Full Text: PDF
We proposed a method of automated scintigram image processing enabling an objective evaluation of the renal parenchyma condition to be made based on scintigram brightness and geometric characteristics with threshold processing. We studied the method using a set of real radionuclide images of a renal transplant. The results of clinical studies confirm the effectiveness of the developed method. We obtained objective numerical values associated with thresholding the image from 40% to 80%, based on which one can form an independent assessment of the presence or absence of focal lesions in the renal parenchyma.
The guide will allow doctors of surgical profile to get information about the meaning of eponymous terms that they face in practice and in the study of special medical literature. The book contains 2008 eponymous symptoms, symptomocomplexes, syndromes and diseases related to the main sections of surgery. The book consists of two parts, the first part of which refers to the semiotics of surgical diseases and presents their symptoms and signs. The second part of the manual includes nosological units, which are divided into 8 chapters – sections of clinical surgery – and systematized in alphabetical order. Their explanation, the historical reference, data on epidemiology of diseases, their etiology and pathogenesis and a clinical picture are given. From the standpoint of modern evidence-based medicine provides information on the diagnosis, treatment and prevention of major surgical diseases. At the end of the book is a subject index, referring to which the reader can easily find the term of interest.
The guide is addressed to a wide range of doctors of surgical profile. It will be useful to researchers, teachers of higher medical school.
Objectives the terminological analysis of the identification of perineal body and associated muscles according to native and foreign literature.
Material and methods.The literature on human anatomy, topographical anatomy, operative surgery, obstetrics, gynecology, proctology as well as urology was reviewed. We analyzed articles from several peer-reviewed scientific medical journals on the topic of the perineum and pelvic organs diseases.
Results.The review of the literature indicates that most of native authors use the term "centrum tendineum perinei" despite last two international anatomical terminology revisions in 2003 and 2019. At the same time, the foreign authors use the term "perineal body" which is in line with contemporary anatomical terminology.
It was also found that the authors disagree on the terminology and morphology not only of the "centrum tendineum perinei" but also of the muscles that form it.
The article focuses on the role of Samara State Medical University in the development of innovative capacity of the Samara region in the sphere of healthcare and medical education. Special attention is given to the multilevel innovative infrastructure of SSMU, which includes such unique departments as the Center for groundbreaking research “IT in medicine”, the scientific and production technology park, scientific-educational centers, small innovative enterprises and others. In particular, this infrastructure is an integrative platform not only for own innovation process at the university, but also for the development of current medical science prospects, for the formation of unique competences in interdisciplinary spheres, for the realization of science-based business, for the organization of innovative educational process (especially in the sphere of simulation technologies), for implementation into clinical practice, and also for successful incorporation into international cooperation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
