Predictors of Unfavourable Outcomes in Children and Adolescents Submitted to Surgical Mitral Valvuloplasty Secondary to Chronic Rheumatic Heart Disease

Abstract Background: Mitral valve repair in paediatric patients with chronic rheumatic heart disease is superior to valve replacement and has been used with good results. Objective: To identify predictors of unfavourable outcomes in children and adolescents submitted to surgical mitral valvuloplasty secondary to rheumatic heart disease. Methods: Retrospective study of 54 patients under the age of 16 operated at a tertiary paediatric hospital between March 2011 and January 2017. The predictors of risk for unfavourable outcomes were: age, ejection fraction, degree of mitral insufficiency, degree of pulmonary hypertension, presence of tricuspid insufficiency, left chamber dilation, preoperative functional classification, duration of cardiopulmonary bypass, duration of anoxia, presence of atrial fibrillation, and duration of vasoactive drug use. The outcomes evaluated were: death, congestive heart failure, reoperation, residual mitral regurgitation, residual mitral stenosis, stroke, bleeding and valve replacement. For all analyzes a value of p

The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

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 ...

Conclusions: The study ’s findings support the efficacy of tube weaning based on the published “Graz model of tube weaning” for children born with EA/TEF and indicate the necessity of specialized tube weaning programs for these patients.What is Known:• Children with esophageal atresia/tracheoesophageal fistula often suffer from feeding problems and tube dependency.• Different tube weaning programs and outcomes have been published, but not specifically for children with EA.What is New:• Evaluation of a large sample of children referred for tube weaning after EA repair.• Most children wi...
