Long-term Outcomes of Mechanical Vs Biologic Aortic Valve Prosthesis in Patients Older Than 70 Years

This study investigated differences in long-term outcomes between SAVR-treated patients more than 70 years of age who received mechanical or biologic prosthetic valves.MethodsAll patients (excluding those with endocarditis) who were more than 70 years of age and who underwent isolated first-time SAVR (with or without coronary artery bypass grafting) in Finland between 2004 and 2014 were retrospectively studied (n = 4227). Propensity score matching (1:3) was used to account for baseline differences (n = 296 with mechanical prostheses and n = 888 with biologic prostheses). Outcomes were 10-year survival, major bleeding (all, gastrointestinal, intracranial), ischemic stroke, infective endocarditis, and aortic valve reoperation. Mean age was 75.8 years, and mean follow-up was 8.3 years.ResultsSurvival at 10 years was 46.1% with mechanical prostheses and 57.8% with biologic prostheses (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.21 to 1.80; P

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...

Conclusion: Our findings indicate that preschool children with a higher score in effortful control had less screen time. Because effortful control reflects general self-regulatory abilities, promoting these skills may be effective in reducing screen time in young children.What is Known:•Screen time has increased rapidly during the last decades, and higher screen time has been linked with numerous adverse health consequences in children.•There are no previous studies investigating associations of long-term stress and temperament with screen time in young children.What is New:•Of the temperament dimensions, ef...

Conclusion Early cardiac surgery in patients with infective endocarditis and stroke maybe lifesaving with a low neurological risk. Comprehensive neurovascular imaging may help in identifying patient-related risk factors.
