Objective: To estimate the pooled incidence of Bell's palsy after COVID-19 vaccination., Methods: PubMed, Scopus, EMBASE, Web of Science, and Google Scholar were searched by 2 independent researchers. We also searched the grey literature including references of the references and conference abstracts. We extracted data regarding the total number of participants, first author, publication year, the country of origin, sex, type of vaccines, and the number of patients who developed Bell's palsy after COVID-19 vaccination., Results: The literature search revealed 370 articles, subsequently deleting duplicates 227 remained. After careful evaluation of the full texts, 20 articles remained for meta-analysis. The most commonly administered vaccines were Pfizer followed by Moderna. In total, 4.54e+07 individuals received vaccines against COVID-19, and 1739 cases developed Bell's palsy. In nine studies, controls (individuals without vaccination) were enrolled. The total number of controls was 1 809 069, of whom 203 developed Bell's palsy. The incidence of Bell's palsy after COVID-19 vaccines was ignorable. The odds of developing Bell's palsy after COVID-19 vaccines was 1.02 (95% CI: 0.79-1.32) (I2 = 74.8%, P < .001)., Conclusion: The results of this systematic review and meta-analysis show that the incidence of peripheral facial palsy after COVID-19 vaccination is ignorable and vaccination does not increase the risk of developing Bell's palsy. Maybe, Bell's palsy is a presenting symptom of a more severe form of COVID-19, so clinicians must be aware of this., (Copyright © 2023 Sociedad Española de Neurología.

Background: Although several genetic biomarkers have been reported in the tocilizumab (TCZ) response in rheumatoid arthritis, no studies have addressed the pharmacogenomics effect of TCZ in COVID-19., Methods: In this prospective longitudinal study, 95 individuals with severe COVID-19 were selected between 2020-2022. The recovery process was measured at 24 h, 48 h, and 10 days before and after taking TCZ. All participants were genotyped using RFLP-PCR. Different genotypes of FCGR2A rs1801274 and IL-6R rs2228145 were compared in terms of the recovery process., Results: 43.2% of patients were male and 56.8% were female with an average age of 58.20(± 16.214) years. The GA genotype for FCGR2A rs1801274 increased the risk of death (OR = 2.83, P = 0.038) and ventilation (OR = 2.71, P = 0.047) in TCZ-treated individuals. However, there was no risk of death and ventilation with IL-6R rs2228145 (P > 0.05). Additionally, docking analysis showed that not only IL6R but also FCGR2A can be a ligand for TCZ., Conclusion: This study provides valuable insights into the impact of genetic variations on the response rate of TCZ in COVID-19 patients. The GA genotype for FCGR2A rs1801274 was associated with poor treatment outcomes., (© 2024. The Author(s).)

Natural resources have long played a prominent part in conventional treatments as a parental source due to their multifaceted functions and lesser side effects. The diversity of marine products is a significant source of possible bioactive chemical compounds with a wide range of potential medicinal applications. Marine organisms produce natural compounds and new drugs with unique properties are produced from these compounds. A lot of bioactive compounds with medicinal properties are extracted from marine invertebrates, including Peptides, Alkaloids, Terpenoids, Steroids. Thus, it can be concluded that marine ecosystems are endowed with natural resources that have a wide range of medicinal properties, and it is important to examine the therapeutic and pharmacological capabilities of these molecules. So, finding particular inhibitors of the COVID-19 in natural compounds will be extremely important. Natural ingredients, in this light, could be a valuable resource in the progression of COVID-19 therapeutic options. Controlling the immunological response in COVID-19 patients may be possible by addressing the PI3K/Akt pathway and regulating T cell responses. T cell effector activity can be improved by preventing anti-viral exhaustion by suppressing PI3K and Akt during the early anti-viral response. The diversity of marine life is a significant supply of potentially bioactive chemical compounds with a broad range of medicinal uses. In this study, some biologically active compounds from marine organisms capable of inhibiting PI3K/AKT and the possible therapeutic targets from these compounds in viral infection COVID-19 have been addressed., Competing Interests: The authors declare that no conflict of interests exists., (© Copyright by the Author(s).

From the early stages of the pandemic, the development and mass production of a safe and effective vaccine seemed like the greatest tool, to win the fight against the virus. In the present study, we comprehensively conducted a systematic review of all current cases worldwide to better understand whether there is a link between COVID-19 vaccination and one of the most devastating complications, cardiac Inflammation. Our search retrieved over 250 results, of which 130 met the inclusion criteria, and their respective data were extracted. The results suggest that postvaccination myocarditis and pericarditis are more likely to be seen in male, younger, and mRNA-vaccinated individuals. Most affected patients experienced symptoms following the second shot, and complaint of chest pain was the most prevalent presentation. Currently, no direct link can be drawn between the vaccines and the risk of cardiac inflammation., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Hamed Ghoshouni et al.)
