The global emergence of the coronavirus disease 2019 (COVID-19) pandemic brought forth the necessity to investigate potential therapeutic attributes of existing drugs, including acyclovir, to combat this novel virus. The primary focus of this research was to assess the theoretical bioactivities of acyclovir derivatives and to evaluate their molecular docking capacities, thereby determining their prospective application in treating COVID-19. A set of 22 ligand molecules derived from acyclovir were carefully selected for this study. Using the one-click docking technique, these derivatives underwent molecular interactions with specific proteins sourced from the Protein Data Bank, identified by IDs 1R4L, 1S49, 1AJ6, and 1PVG. The molecular docking analysis revealed that acyclovir derivatives no. 3, 5, 8, and 14 displayed the highest docking scores and could be potential candidates as therapeutic agents against COVID-19 based on these scores. Further experimental validations are essential to establish their efficacy in clinical settings.</p>","PeriodicalId":16386,"journal":{"name":"Journal of Medicine and Life","volume":"17 9","pages":"840-847"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11611060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142769764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A retrospective analysis was conducted on a cohort of patients diagnosed with COVID-19. Coagulation parameters, including PT, PTT, and INR, were measured upon admission. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive performance of these parameters. Sensitivity and specificity were calculated, and the area under the curve (AUC) values were determined. The analysis included 156 patients diagnosed with COVID-19. The <i>t</i>-test revealed a significant difference (<i>P</i> < 0.05) in PTT, PT, and INR. PTT demonstrated the highest predictive performance, with an AUC value of 0.68, indicating superior discrimination compared with PT and INR. PTT exhibited a sensitivity of 83% and a specificity of 46% for identifying deceased patients. These findings suggest that PTT may serve as a valuable prognostic marker of mortality risk in patients with COVID-19. Coagulation indicators, particularly PTT, predicted COVID-19 mortality. Monitoring coagulation markers may help stratify the risk and guide treatment.

This cross-sectional study investigated the relationship between resilience and impostor syndrome among undergraduate nursing and medical students at King Saud Bin Abdulaziz University for Health Sciences. A total of 300 students were recruited using a convenience sample and completed self-reported questionnaires assessing resilience and impostor syndrome between September 2022 and March 2023. Various bias mitigation strategies were employed to ensure data accuracy and reliability, such as anonymous data collection and validated scales. The results indicated that less than half of the participants experienced impostor syndrome. Among nursing students, 41.7% were classified as severe, 37.7% as moderate, and 13.0% as intense impostors. For medical students, 4.6% were mild, 4.6% moderate, 4.5% severe, and 4.5% intense impostors. Mean resilience scores were 24.3 ± 7.15 for nursing students and 25.6 ± 7.22 for medical students. A significant negative correlation was found between resilience and impostor syndrome scores (r = -0.220, <i>P</i> < .001).
