1Clinical outcomes of tricuspid valve repair accompanying left-sided heart disease显示文摘AIM To determine whether the need for additional tricuspid valve repair is an independent risk factor when surgery is required for a left-sided heart disease.METHODS One hundred and eighty patients(68 ± 12 years,79 males) underwent tricuspid annuoplasty.Cox proportionalhazards regression model for multivariate analysis was performed for variables found significant in univariate analyses.RESULTS Tricuspid regurgitation etiology was functional in 154 cases(86%),organic in 16 cases(9%),and mixed in10 cases(6%),respectively.Postoperative mortality at 30 days was 11.7%.Mean follow-up was 51.7 mo with survival at 5 years of 73.5%.Risk factors for mortality were acute endocarditis [hazard ratio(HR) = 9.22(95%CI:2.87-29.62),P < 0.001],ischemic heart disease requiring myocardial revascularization [HR = 2.79(1.26-6.20),P = 0.012],and aortic valve stenosis [HR = 2.6(1.15-5.85),P = 0.021].Significant predictive factors from univariate analyses were double-valve replacement combined with tricuspid annuloplasty [HR = 2.21(1.11-4.39),P = 0.003] and preoperatively impaired ejection fraction [HR = 1.98(1.04-3.92),P = 0.044].However,successful mitral valve repair showed a protective effect [HR = 0.32(0.10-0.98),P = 0.046].Additionally,in instances where tricuspid regurgitation required the need for concomitant tricuspid valve repair,mortality predictor scores such as Euroscore 2 could be shortened to a simple Euroscore-tricuspid comprised of only 7 inputs.The explanation may lie in the fact that significant tricuspid regurgitation following leftsided heart disease represents an independent risk factor encompassing several other factors such as pulmonary arterial hypertension and dyspnea.CONCLUSION Tricuspid annuloplasty should be used more often as a concomitant procedure in the presence of relevant tricuspid regurgitation,although it usually reveals an overly delayed correction of a left-sided heart disease.Kasra Azarnoush Ahmad S Nadeemy Bruno Pereira Massoud A Leesar Céline Lambert Alaa Azhari Vedat Eljezi Nicolas Dauphin Etienne Geoffroy Lionel Camilleri 2017World Journal of Cardiology2017,9,10:4
2Current 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
