ABSTRACT
In this overview, we discuss the impact of antibiotic therapy on the COVID infection, the complications after vaccination, possible causes of adverse events, and ways to protect against pandemic infection, as well as try to dispel myths about COVID. Antibiotics are necessary only in case of secondary infection, but overlapping with bacterial infection mainly occurs after hospitalization, and the vast majority of infections were caused by the Acinetobacter baumannii strain. Commonly used antimicrobial disinfectants are chlorhexidine derivatives;due to their frequent use, microorganisms have become resistant to them, and in addition, chloroquine has no clinical benefit in the treatment of COVID-19. Virus escapes from the immune response due to multiple mutations in the receptor-binding domain, or the N-terminal end, which are the sites responsible for antibody binding and virus neutralization. The COVID infection itself is characterized by a rather powerful suppression of immunity. For this reason, the use of antibiotics in the absence of a secondary infection layer leads to greater suppression of the immune system and an aggravation of the process, which often ends up fatally. Immune dysregulation predisposes to the development of severe COVID-19. A decrease in the number of leukocytes gives an unfavorable prognosis for the severity of the COVID infection course. The main reason for the death cases after vaccination seems to be an increase in blood clotting, which is observed not only among the population over 60 years old, but also amid young people.
ABSTRACT
Objectives: The rationale of this study was to compare the efficiency of online learning and the differences in outcome between the two universities in India and United Arab Emirates (UAE). Materials and Methods: A cross-sectional study was conducted with a validated questionnaire among dental students of a dental college in India and a dental college in the UAE. The data were analyzed using the SPSS software version 22, and comparison was done using the Chi-square test, ANOVA, correlation, and regression analysis. Statistical significance was set at P < 0.05. Results: A total of 491 students responded to the questionnaire, of which 314 were from India and 177 from UAE. The awareness of online learning among students had increased after COVID-19, and Zoom was the most common platform (30.9%). The satisfaction ratio was 78.4%, and smartphones were commonly used by students. Based on the satisfaction of online learning, study participants from UAE had a higher mean attitude score (2.72 ± 0.98) as compared to Indian students (2.47 ± 0.77) (P < 0.027*). Conclusion: The study results show that online learning was comparable to traditional method of learning. Although poor network connectivity was a deterrent for online learning among students from India and UAE, future teaching methods could inculcate online teaching methods and hence encourage blended learning as part of the teaching curriculum.
