Meta AnalysisRenin-Angiotensin System Inhibitors and COVID-19: a Systematic Review and Meta-Analysis. Evidence for Significant Geographical Disparities.
While the COVID-19 pandemic is constantly evolving, it remains unclear whether the use of angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) affects the clinical course of SARS-CoV-2 infection. For this meta-analysis, PubMed, CENTRAL, and grey literature were searched from their inception to 19 May 2020 for randomized, controlled trials or observational studies that evaluate the association between the use of either ACE inhibitors or ARBs and the risk for major clinical endpoints (infection, hospitalization, admission to ICU, death) in adult patients during the COVID-19 pandemic. In addition, a subgroup geographical analysis of outcomes was performed. Studies including less than 100 subjects were excluded from our analysis. ⋯ In total, 25 observational studies were included. ACE inhibitors and ARBs were not associated with increased odds for SARS-CoV-2 infection, admission to hospital, severe or critical illness, admission to ICU, and SARS-CoV-2-related death. In Asian countries, the use of ACE inhibitors/ARBs decreased the odds for severe or critical illness and death (OR = 0.37, 95% CI 0.16-0.89, I2 = 83%, and OR = 0.62, 95% CI 0.39-0.99, I2 = 0%, respectively), whereas they increased the odds for ICU admission in North America and death in Europe (OR = 1.75, 95% CI 1.37-2.23, I2 = 0%, and OR = 1.68, 95% CI 1.05-2.70, I2 = 82%, respectively). ACE inhibitors might be marginally protective regarding SARS-CoV-2-related death compared with ARBs (OR = 0.86, 95% CI 0.74-1.00, I2 = 0%). Randomized controlled trials are needed to confirm the aforementioned associations between ACE inhibitors, ARBs, and SARS-CoV-2.

Meta AnalysisTracing open data in emergencies: the case of the COVID-19 pandemic.
The coronavirus disease 2019 (COVID-19) pandemic constitutes an ongoing, burning Public Health Emergency of International Concern (PHEIC). In 2015, the World Health Organization adopted an open data policy recommendation in such situations. ⋯ Even though a large number of manuscripts was produced since the pandemic, availability of open data remains restricted.

SARS-CoV-2 detection in different respiratory sites: A systematic review and meta-analysis.
The accurate detection of SARS-CoV-2 through respiratory sampling is critical for the prevention of further transmission and the timely initiation of treatment for COVID-19. There is a diverse range of SARS-CoV-2 detection rates in reported studies, with uncertainty as to the optimal sampling strategy for COVID-19 diagnosis and monitoring. ⋯ This study was funded in part by the NIH grants U01AI106701 and by the Harvard University for AIDS Research (NIAID 5P30AI060354).

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has resulted in hundreds of thousands of deaths worldwide. While the majority of people with COVID-19 won't require hospitalization, those who do may experience severe life-threatening complications, including acute respiratory distress syndrome. SARS-CoV-2 infects human cells by binding to the cellular surface protein angiotensin-converting enzyme 2 (ACE2); in addition, the cellular transmembrane serine protease 2 (TMPRSS2) is needed for priming of the spike (S) protein of the virus. ⋯ Regarding currently investigated therapies interferon-beta induced ACE2 gene expression in bronchial epithelial cells, while chloroquine tends to upregulate CTSB/L genes. Finally, we analyzed KEGG pathways modulated by ACE2, TMPRSS2 and CTSB/L and probed DrugBank for drugs that target modules of the affected pathways. Our data indicate possible novel high-risk groups for COVID-19; provide a rich resource for future investigations of its pathogenesis and highlight the therapeutic challenges we face.

Meta Analysis
Coronavirus disease (COVID-19) and the liver: a comprehensive systematic review and meta-analysis.
Liver function derangements have been reported in coronavirus disease (COVID-19), but reported rates are variable. ⋯ The most frequent abnormality in liver functions was hypoalbuminemia followed by derangements in gamma-glutamyl transferase and aminotransferases, and these abnormalities were more frequent in severe disease. The systematic review was, however, limited by heterogeneity in definitions of severity and liver function derangements. Graphical depiction of the summary of meta-analytic findings a) pooled prevalence of abnormalities b) Risk ratio of abnormality in severe versus non-severe COVID-19 c) standardized mean difference (SMD) between severe and non-severe group and d) pooled prevalence for parameters based on severity stratification for bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), albumin, globulin and acute hepatic injury (AHI) . Also estimates for overall/total liver disease (TLD) and chronic liver disease (CLD) amongst COVID-19 patients are depicted in a, b, d. For d) In addition to severity stratification, Overall (all studies for a particular estimate) and combined (only those studies which reported severity) estimates are provided.
