Review Meta Analysis
Acute kidney injury in COVID-19 patients receiving remdesivir: A systematic review and meta-analysis of randomized clinical trials.
Remdesivir is an antiviral agent with positive effects on the prognosis of Coronavirus Disease (COVID-19). However, there are concerns about the detrimental effects of remdesivir on kidney function which might consequently lead to Acute Kidney Injury (AKI). In this study, we aim to determine whether remdesivir use in COVID-19 patients increases the risk of AKI. ⋯ Our study suggested that remdesivir treatment probably has little or no effect on the risk of AKI in COVID-19 patients.

Meta Analysis
Evaluation of oral small molecule drugs for the treatment of COVID-19 patients: a systematic review and network meta-analysis.
At present, there are some randomized controlled trials (RCTs) of oral small molecule drugs. The purpose of this study was to evaluate the efficacy and safety of oral small molecule drug treatment for COVID-19. ⋯ When compared to other antiviral medications, paxlovid can reduce the mortality and hospitalization of COVID-19 patients.

Meta Analysis
Anticoagulation therapy in hospitalized patients with COVID-19: a meta-analysis of randomized clinical trials.
Thromboembolic events are common in hospitalized patients with COVID-19, suggesting that SARS-CoV-2 infection may be related to a prothrombotic state. Several clinical trials evaluating different anticoagulation strategies were developed. Thus, we proposed conducting a meta-analysis of randomized clinical trials that evaluated the efficacy and safety of therapeutic anticoagulation with heparins in hospitalized patients with COVID-19. ⋯ This meta-analysis did not show a reduction in all-cause mortality in hospitalized patients with COVID-19 who received anticoagulation with heparin at a therapeutic dose compared to those who received a prophylactic/intermediate dose, as well as no significant differences were found in the need of intensive care unit admission or use of non-invasive ventilation. There was, however, a reduction in thromboembolic events, pulmonary embolism, and increased bleeding (Tab. 1, Fig. 5, Ref. 31). Keywords: COVID-19, anticoagulation, heparins, meta-analysis.

To summarize the data on SARS-CoV-2 seroprevalence surveys conducted in Brazil before the introduction of vaccines METHODS: The authors conducted a systematic review and meta-analysis on the seroprevalence of SARS-CoV-2 infection in Brazil. The present review followed the PRISMA guidelines. The authors searched Medline, Embase, and LILACS databases for serologic surveys conducted in the Brazilian population, in the period from 01/10/2019 to 07/11/2021, without language restrictions. The authors included studies that presented data concerning SARS-CoV-2 antibodies seroprevalence in Brazil and had a sample size ≥50 individuals. Considering the expected heterogeneity between studies, all analyses were performed using the random effects model, and heterogeneity was assessed using the I2 statistic RESULTS: Of 586 publications identified in the initial searches, 54 were included in the review and meta-analysis, which contained the results of 135 surveys, with 336,620 participants. The estimated seroprevalence was 11.0%, ranging from 1.0% to 83.0%, with a substantial heterogeneity (I2 = 99.55%). In subgroup analyses, the authors observed that the prevalence of SARS-CoV-2 antibodies was 13.0% in blood donors, 9.0% in the population-based surveys, 13% in schoolchildren, and 11.0% in healthcare workers. ⋯ Seroprevalence increases over time. Large differences were observed among the regions of the country. It was higher in the Northern region, decreasing towards the South. The present results may contribute to the analysis of the spread of SARS-CoV-2 infection in the Brazilian population before vaccination, one of the factors that may be influencing the clinical presentation of COVID-19 cases related to the new variants, as well as the effectiveness of the vaccination program.

Review Meta Analysis
Concomitant Guillain-Barré Syndrome and COVID-19: A Meta-Analysis of Cases.
Background and Objectives: Recent findings demonstrate that the transmigration of severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) to the nervous system implicates severe neurotropic pathologies, including the onset of the rare disease called Guillain-Barré syndrome (GBS) which is characterized by immune-mediated polyneuropathy. This study aimed to identify the predisposing factors and the clinical features of coronavirus disease 2019 (COVID-19)-induced GBS. Materials and Methods: We have performed an analysis of 147 cases. ⋯ Among the cases, patient mortality was 10.9%. Conclusions: A gap of knowledge exists regarding the complete spectrum of clinical characteristics of COVID-19-related GBS. Recent findings suggest that SARS-CoV-2 triggers GBS, as it follows a similar para-infectious pattern as the other viral agents contributing to the onset of GBS.
