Circulating High Mobility Group Box-1 Does Not Predict Pulmonary Arterial Hypertension in Children with Congenital Heart Disease: A Prospective Cohort Study.
Pulmonary arterial hypertension (PAH) is a devastating complication of pediatric congenital heart disease (CHD). A recent study has identified the protein high mobility group box-1 (HMGB1) as a diagnostic tool in adults with CHD-associated PAH. HMGB1 levels in adults with CHD-associated PAH correlated with mean pulmonary artery pressure and pulmonary vascular resistance, and HGMB1 levels fell in response to sildenafil therapy. We wanted to assess if HGMB1 was a biomarker of pediatric CHD-PAH. ⋯ Unlike in adults, HGMB1 is not a biomarker of PAH in pediatric CHD. Further work will continue to explore for biomarkers for this high-risk population.

Review Meta AnalysisEffect of Preoperative Recombinant Human Erythropoietin on the Need for Blood Transfusion and Surgical Outcomes in Adult Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-Analysis with Trial Sequential Analysis.
This study aimed to examine the value of preoperative recombinant human erythropoietin (rhEPO) administration to adults undergoing elective cardiac surgery. Databases were searched for randomized controlled trials (RCTs) comparing rhEPO plus standard treatment versus standard treatment only. Primary outcomes were the need for and volume of homologous blood transfusion (HBT). ⋯ Trial sequential analysis showed that rhEPO was superior to standard treatment only for reducing the need for and volume of HBT. Regarding secondary outcomes, there was moderate certainty that rhEPO is associated with a limited reduction in the length of ICU (Hedges g = -0.10; 95% CI, -0.19 to -0.01) and hospital stay (Hedges g = -0.13; 95% CI = -0.25 to -0.02), and low certainty for increased risk of myocardial infarction, with a number needed to harm of 36.1 (95% CI, 17.9-127.4). More well-designed, adequately powered RCTs are needed to draw conclusions regarding the value of rhEPO.

Comparative StudyLocoregional Versus General Anesthesia for Carotid Artery Stenting in the American College of Surgeons National Surgical Quality Improvement Project.
Carotid artery stenting (CAS) may be performed by transfemoral or transcervical (TCAR) approaches and with a variety of anesthetic techniques. No current literature clearly supports one anesthetic method over another. We therefore sought to evaluate the outcomes of CAS procedures based on anesthetic approach. ⋯ In patients undergoing CAS in the National Surgical Quality Improvement Program, GA was not associated with the composite outcome but was associated with increased rates of postoperative pneumonia and decreased rates of MI. Further investigation should attempt to better clarify these relationships.

ReviewAn Update on Guidelines to Prevent and Manage Atrial Fibrillation After Cardiac Surgery and a Survey of Practice in the UK.
Postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery and affects around 30% of patients. Variable guidelines from multiple organizations exist for the prevention of POAF after cardiac surgery. A survey of UK practice was conducted to define "usual care" for a platform trial of interventions to prevent POAF after cardiac surgery. To provide context for the survey, all current guidelines for the prevention and management of atrial fibrillation (AF) after cardiac surgery were reviewed. ⋯ Guidance to prevent AF after cardiac surgery centers around the use of β-blockade. Although patients in the UK do not appear to be risk-assessed for POAF, the main interventions used to prevent it are similar: β-blockade and maintenance of serum K+ and Mg2+ levels.
