Placental vascular remodeling in pregnant women with COVID-19

Severe acute respiratory syndrome coronavirus 2 has been causing the pandemic of coronavirus disease 2019 (COVID-19) that has so far resulted in over 450 million infections and six million deaths. This respiratory virus uses angiotensin-converting enzyme 2 as a receptor to enter host cells and affects various tissues in addition to the lungs. The present study reports that the placental arteries of women who gave birth to live full-term newborns while developing COVID-19 during pregnancy exhibit severe vascular wall thickening and the occlusion of the vascular lumen. A morphometric analysis of the placental arteries stained with hematoxylin and eosin suggests a 2-fold increase in wall thickness and a 5-fold decrease in the lumen area. Placental vascular remodeling was found to occur in all of SARS-CoV-2-positive mothers as defined by RT-PCR. Immunohistochemistry with α-smooth muscle actin and the Kv11.1 channel as well as Masson's trichrome staining showed that such placental vascular remodeling in COVID-19 is associated with smooth muscle proliferation and fibrosis. Placental vascular remodeling may represent a response mechanism to the clinical problems associated with childbirth in COVID-19 patients.

INDIVIDUAL FACTORS OF MEDICAL PHD STUDENTS' ENGLISH COMMUNICATIVE COMPETENCE

OBJECTIVE

The aim: The paper is aimed to find correlations between English language communicative academic and medical competence components (theoretical, practical, and individual by certain methods), to improve design of the course "Academic English for PhDs in Medicine", its methods and strategy.

PATIENTS AND METHODS

Materials and methods: The study sample includes postgraduate groups studying for PhD in Healthcare, aged 21-59 years, in Bukovinian State Medical University (39 respondents), Zaporizhzhia State Medical University (32 respondents), Kharkiv Medical Academy of Postgraduate Education (33 respondents), and Bogomolets National Medical University (318 respondents). The study was held in 2019-2023. We assessed theoretical and practical components using our tests, individual component - psychological methods. The values of three components were transformed into general English communicative academic and medical competence level. The data were treated with SPSS Statistica 18.0, using Spearman correlation significance.

RESULTS

Results: We found positive correlation between English communicative competence and communicative tolerance, general communicative skills level, and high or medium communicative control level. Also, positive correlation characterizes interaction as a conflict-resolving strategy and communicative competence. Highly manifested intolerance in communication, predominance of negative mindsets, intolerance to stress negatively affect the level of English communicative academic and professional competence of PhD students.

CONCLUSION

Conclusions: Analysis of the English speaking competence, and its components, showed positive correlation between interaction as a conflict-resolving strategy and English communicative competence of respondents. Regarding the results, the curriculum of the "Academic English for Medical PhDs" should be modified, including interactive methods, case studies, problem solving, and other methods for individual component training.

PHYSICAL HEALTH OF STUDENTS AND DIGITALIZATION OF HIGHER MEDICAL EDUCATION: RISK FACTORS

OBJECTIVE

The aim: To study the dynamics of gadget use by higher education students of the Bogomolets National Medical University and to assess technological impact on the physical health of students.

PATIENTS AND METHODS

Materials and methods: To accomplish the tasks set using theoretical and experimental methods of scientific research: systematic analysis, comparison and generalization of the bibliosemantic method, questionnaires, and interviews with students. Quantitative data collected during the survey of students studying in the «Dentistry», «Pediatrics», «Medicine», «Pharmacy, Industrial Pharmacy», «Physical Therapy, Occupational Therapy», and «Medical Psychology» specialties were processed using the MedCalc statistical software, and there was carried out comparative analysis afterwards.

RESULTS

Results: During the quarantine and martial law, medical university students were forced to study distantly or in a mixed format using various gadgets and computers. It is obvious that the physical condition of a person is affected by the duration of their use of various devices. In this paper, therefore, the risks and the researched dynamics of gadget use by higher education students of the Bogomolets National Medical University were identified. Thus, the technological impact on the physical health of students was also defined. Moreover, the data based on the results of height and weigh calculation of higher education students, which used to diagnose types of obesity by anthropometric indicators, were also collected.

CONCLUSION

Conclusions: According to the results of the research, it was established that the students of the Bogomolets National Medical University spent a significant part of their study time sitting in the classroom or at the computer (40 hours weekly average). We found that in the process of distance learning, prolonged sitting at a PC or other gadget (as well as general sedentary lifestyle) has affected the female higher education students majoring in 222 «Medicine» course their body mass index. The time spent using gadgets both in the educational and non-formal education (self-education) processes has increased significantly. We attribute this fact to the emergence of a significant number of online educational resources in the public domain, the growing number of webinars, trainings, and master classes conducted by both domestic and foreign experts online.

New training, new attitudes: non-clinical components in Ukrainian medical PHDs training (regarding critical thinking, academic integrity and artificial intelligence use)

OBJECTIVE

Aim: The paper studies the attitude to critical thinking, academic integrity and the Artificial Intelligence use of the Ukrainian medical PhD students.

PATIENTS AND METHODS

Materials and Methods: In 2023, 56 medical PhD students from the Bogomolets National Medical University, Kyiv, Ukraine, underwent the survey. The participation was voluntary, upon the oral consent. The data included in the survey questions include various aspects related to critical thinking, analysis skills, and attitudes towards plagiarism.

RESULTS

Results: A significant majority of the medical PhD students (75%) place high importance on critical thinking. While a majority (89.29%) apply analysis and critical thinking skills in their English studies, there's a notable percentage (7.14%) that is uncertain. Although most are aware of the unacceptability of cheating and plagiarism (75%), a small proportion admit to having plagiarized (12.5%). Only 30.4% of the respondents reported using GPT Chat for study. Responses to witnessing peers plagiarize or using Artificial Intelligence show a varied attitude, with many expressing unwillingness to report such incidents (30.36%).

CONCLUSION

Conclusions: The survey highlights the recognized importance of critical thinking in academic study among medical PhD students, while also points to areas where attitudes and practices regarding these skills could be improved. The study shows a vast area for improvement regarding academic integrity, as almost one-third of respondents need more defined standards. This definitely puts some questions before the present medical postgraduate education, and requires change of the educational paradigm, clear rules of academic conduct, and a system of control.
