1Current systematic reviews and meta-analyses of COVID-19显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)has left a significant impact on the world's health,economic and political systems;as of November 20,2020,more than 57 million people have been infected worldwide,with over 1.3 million deaths.While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life.AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence,highlight gaps in knowledge,and elucidate further meta-analyses and umbrella reviews that are yet to be performed.METHODS We explored studies based on systematic reviews and meta-analyses with the keyterms,including severe acute respiratory syndrome(SARS),SARS virus,coronavirus disease,COVID-19,and SARS coronavirus-2.The included studies were extracted from Embase,Medline,and Cochrane databases.The publication timeframe of included studies ranged between January 01,2020,to October 30,2020.Studies that were published in languages other than English were not considered for this systematic review.The finalized full-text articles are freely accessible in the public domain.RESULTS Searching Embase,Medline,and Cochrane databases resulted in 1906,669,and 19 results,respectively,that comprised 2594 studies.515 duplicates were subsequently removed,leaving 2079 studies.The inclusion criteria were systematic reviews or meta-analyses.860 results were excluded for being a review article,scope review,rapid review,panel review,or guideline that produced a total of 1219 studies.After screening articles were categorized,the included articles were put into main groups of clinical presentation,epi-demiology,screening and diagnosis,severity assessment,special populations,and treatment.Subsequently,there was a second subclassification into the following groups:gastrointestinal,cardiovascular,neurological,stroke,thrombosis,anosmia and dysgeusia,ocular manifestations,nephrology,cutaneous manifestations,D-dimer,lymphocyte,anticoagulation,antivirals,convalescent plasma,immunosuppressants,corticosteroids,hydroxychloroquine,renin-angiotensin-aldosterone system,technology,diabetes mellitus,obesity,pregnancy,children,mental health,smoking,cancer,and transplant.CONCLUSION Among the included articles,it is clear that further research is needed regarding treatment options and vaccines.With more studies,data will be less heterogeneous,and statistical analysis can be better applied to provide more robust clinical evidence.This study was not designed to give recommendations regarding the management of COVID-19.Mahmoud Nassar Nso Nso Mostafa Alfishawy Anastasia Novikov Salim Yaghi Luis Medina Bahtiyar Toz Sofia Lakhdar Zarwa Idrees Yungmin Kim Dawa Ongyal Gurung Raheel S Siddiqui David Zheng Mariam Agladze Vikram Sumbly Jasmine Sandhu Francisco Cuevas Castillo Nadya Chowdhury Ravali Kondaveeti Sakil Bhuiyan Laura Guzman Perez Riki Ranat Carlos Gonzalez Harangad Bhangoo John Williams Alaa Eldin Osman Joyce Kong Jonathan Ariyaratnam Mahmoud Mohamed Ismail Omran Mariely Lopez Akwe Nyabera Ian Landry Saba Iqbal Anoosh Zafar Gondal Sameen Hassan Ahmed Daoud Bahaaeldin Baraka Theo Trandafirescu Vincent Rizzo 2021World Journal of Virology2021,10,4:2
2ABO incompatibility in renal transplantation显示文摘ABO blood group incompatibility(ABO-I)was historically considered an absolute contraindication to kidney transplantation due to the significant risk of acute antibody-mediated rejection and early graft loss.Nevertheless,the urge to minimize the gap between the candidates’number on the waitlist for kidney transplants and the available kidney donors encourage investigation into finding ways to use organs from ABO-I kidney donors,especially in the era of using more potent immunosuppression therapies.This review aims to discuss a general overview of ABO-I kidney transplantation and the different protocols adopted by some transplant centers to meaningfully overcome this barrier.Mahmoud Mohamed Tara Sweeney Duaa Alkhader Mahmoud Nassar Ahmed Alqassieh Sofia Lakhdar Nso Nso Tibor Fulop Ahmed Daoud Karim M Soliman 2021World Journal of Transplantation2021,11,9:2

11Mortality rate of COVID-19 infection in end stage kidney disease patients on maintenance hemodialysis:A systematic review and meta-analysis显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)has been the most talked-about disease of the past few years.Patients with significant comorbidities have been at particular risk of adverse outcomes.This study looked at the outcomes and risk factors for adverse outcomes among patients on chronic hemodialysis for end-stage renal disease,a group of patients known to be particularly susceptible to infectious complications.AIM To assess outcomes and risk factors for adverse outcomes of COVID-19 infection among patients on chronic hemodialysis.METHODS We searched PubMed/MEDLINE,EMBASE,Reference Citation Analysis(http://gffzzb1f9d057b5954674spxwnqn60wqxq6509.ffgz.tsg.suse.edu.cn/)and Web of Science databases for relevant terms and imported the results into the Covidence platform.From there,studies were assessed in two stages for relevance and quality,and data from studies that satisfied all the requirements were extracted into a spreadsheet.The data was then analyzed descriptively and statistically.RESULTS Of the 920 studies identified through the initial database search,only 17 were included in the final analysis.The studies included in the analysis were mostly carried out during the first wave.We found that COVID-19 incidence among patients on hemodialysis was significant,over 10%in some studies.Those who developed COVID-19 infection were most likely going to be hospitalized,and over 1 in 5 died from the infection.Intensive care unit admission rate was lower than the infection lethality rate.Biochemical abnormalities and dyspnea were generally reported to be associated with adverse outcomes.CONCLUSION This systematic review confirms that patients on chronic hemodialysis are very high-risk individuals for COVID-19 infections,and a significant proportion was infected during the first wave.Their prognosis is overall much worse than in the general population,and every effort needs to be made to decrease their exposure.Ivan Cancarevic Mahmoud Nassar Ahmed Daoud Hatem Ali Nso Nso Angelica Sanchez Avish Parikh Asma Ul Hosna Bhavana Devanabanda Nazakat Ahmed Karim M Soliman 2022World Journal of Virology2022,11,5:1
