In order to improve the distance learning experience for undergraduate medical education, this study aims to evaluate the teaching methods used by universities in Jordan during the distance learning period and identify the best methods in this situation based on non-university educational avenues utilized by medical students during COVID-19. We conducted a survey of 195 medical students from universities across the country using a questionnaire that measures how dependent students are on educational resources provided by universities before and during the distance learning condition and looks into medical students' most used non-university learning methods in face-to-face and distance learning conditions, and the extent to which medical students used them. We found that the main methods used by medical students for non-university learning were non-university educational videos like YouTube videos (92.8%) and non-university textual explanations (i.e., explanations on websites and summaries of materials made by other students) (67.7%). Before the remote learning situation, there was a large reliance on non-university learning materials, which rose significantly during the distance learning situation (p<0.001, r=0.54). We conducted a polychoric correlations-based Exploratory Factor Analysis (EFA) on 10 items, 7 of which were retained in the final model that revealed 2 factors, to analyze the relationship between the universities' educational methods used in distance learning and the non-university methods medical students used. The first factor reflected the change in "students' use of non-university visualization learning methods in distance learning" (external videos, general dependence on non-university methods, and simulation apps had the highest significant loadings (>0.3)). The second factor reflected the change in "universities' use of visualization and interactive learning methods in distance learning" (deductive discussions, educational videos, and practical methods had significant loadings). A moderately negative correlation was detected between the two factors after applying a Promax rotation (r=-0.41), indicating that the decrease in universities' use of visualization and interactive learning aids in connection with insufficient visualization in the distance educational sessions increased students' use of the aforementioned visualized learning methods in distance learning. This study identifies the optimal visual teaching aids to improve distance undergraduate medical education.

This paper shows how SARS-CoV-2 alters tight junctions (TJs) in human organs. The effect of SARS-CoV-2 on the ACE/Ang II/AT1R pathway and immune cells culminates in the release of numerous pro-inflammatory mediators, leading to the presence of certain symptoms in COVID-19, such as acute lung injury (ALI), pulmonary hypertension, and pulmonary fibrosis. Furthermore, the cytokines released alter different TJs components. The study shows how the irregular release of pro-inflammatory cytokines leads to claudin disruption in various tissues of the body, resulting in different symptoms, such as alveolar fibrosis, pulmonary edema, conjunctivitis, altered fertility in males, gastrointestinal symptoms, Covid toes, and others. SARS-CoV-2 also alters occludin expression in the endothelial and blood-testis barriers (BTB) resulting in edema and altered fertility. Viral disruption of JAM-A leads to activation of the RhoA GTPase, which leads to ALI. Taken together, these results define ACE/Ang II/AT1R pathway receptors and tight junctional components as potential therapeutic targets in COVID-19.

This study aims to evaluate medical students’ impressions and attitudes toward scientific journal articles, and their accessibility to them in one of the developing countries, Jordan. Fourteen questions were asked to medical students to assess their knowledge and accessibility to papers, and to discover the impact of low interest in scientific papers on students’ dealing with COVID-19. Data were analyzed using descriptive and analytical statistics.The study found that there is an unsatisfactory reading for scientific journal articles among medical students, with only 47.2% of students reading them. Furthermore, there are unsatisfactory results regarding students’ knowledge about journal types from the trust perspective (i.e., predatory and reliable journals). This was mainly because of a lack of adequate universal teaching about scientific journal articles, as 86.7% of medical students reported that their universities do not teach them about scientific journal articles. The absence of comprehensive learning about scientific journal articles had a potential negative impact on the medical student’s handling of COVID-19 socially (i.e., advising people in the community about vaccination importance, social distancing, and other preventive measures).Librarians should be involved primarily in undergraduate education related to scientific journal articles, and their role in providing subscription-based journals free of charge, as well as protecting students from predatory journals through suitable library instructions, is essential.
