Illness Severity of Children Admitted to the PICU From Referring Emergency Departments.

Objectives: To compare patient factors and outcomes among children admitted to PICUs from referring versus children's hospital emergency departments (EDs).

Methods: Pediatric patients (<19 years old) admitted to PICUs from referring and children's hospital EDs from July 1, 2011 to June 30, 2013. We compared demographic and clinical factors, including severity of illness as measured by a recalibrated Pediatric Index of Mortality, version 2 score.

Association between Down syndrome and in-hospital death among children undergoing surgery for congenital heart disease: a US population-based study.

Background: The prevalence of Down syndrome (DS)-affected births has increased during the past 30 years; moreover, children with DS have a higher incidence of congenital heart disease compared with their peers. Whether children with DS have better or worse outcomes after repair of congenital heart disease is unclear. We sought to identify differences in in-hospital mortality after cardiac surgery in pediatric patients with and without DS using a large national database.

Gene transfer of heme oxygenase-1 using an adeno-associated virus serotype 6 vector prolongs cardiac allograft survival.

Introduction. Allograft survival can be prolonged by overexpression of cytoprotective genes such as heme oxygenase-1 (HO-1). Modifications in vector design and delivery have provided new opportunities to safely and effectively administer HO-1 into the heart prior to transplantation to improve long-term graft outcome.

Intragraft gene expression profile associated with the induction of tolerance.

Background: Xenotransplantation holds the promise of providing an unlimited supply of donor organs for terminal patients with organ failure. Pre-existing natural antibodies to the Galalpha1,3Galbeta1,4GlcNac-R (alphaGal) carbohydrate xenoantigen, however, bind rapidly to the graft endothelium and initiate hyperacute rejection of wild type pig grafts in humans. Experimental procedures designed to prevent xenoantibody-mediated rejection have been tested in gal knockout mice.
