OBJECTIVE: Stage 1 Norwood palliation is one of the highest risk procedures in congenital cardiac surgery. Patients with superior technical performance scores have more favorable outcomes. Intraoperative epicardial echocardiography may allow the surgeon to address residual lesions prior to leaving the operating room, resulting in improved technical performance. The ability of intraoperative epicardial echocardiography to visualize the relevant anatomy and its association with outcomes is not known...

A restrictive transfusion strategy led us to routinely try to conduct donor-blood free open-heart surgery even in neonates. The cardio-pulmonary bypass (CPB) circuit was minimized by priming volumina at 73 ml for the smallest patients with body weight up to 2.5 kg and 85-95 ml for those with body weight of more than 2.5 kg, and by positioning the console as close as possible to operation table. Measures were applied to save blood during the procedure. Transfusion threshold of 8 g/dl hemoglobin was retained...

OBJECTIVE: The study objective was to evaluate the outcomes of the cavopulmonary shunt after the Norwood procedure with a particular focus on age, weight, and whether surgery was planned or expedited by clinical findings. METHODS: We studied 297 consecutive patients with hypoplastic left heart syndrome undergoing the cavopulmonary shunt operation between 2002 and 2014. All patients underwent the Norwood procedure with a right ventricle to pulmonary artery conduit...

BACKGROUND: The aim of this study was to evaluate outcome measures after the use of del Nido (dN) cardioplegia compared with conventional multidose high-potassium (non-dN) cardioplegia in neonates and infants. METHODS: We retrospectively analyzed data in patients, aged younger than 1 year, undergoing cardiopulmonary bypass (CPB) from January 2012 to August 2015. We changed our cardioplegia protocol from non-dN to dN administered in a single or infrequently dosed strategy in September 2013...

The secondary xylem of conifers is composed mainly of tracheids that differ anatomically and chemically from angiosperm xylem cells. There is currently no high-spatial-resolution data available profiling gene expression during wood formation for any coniferous species, which limits insight into tracheid development. RNA-sequencing data from replicated, high-spatial-resolution section series throughout the cambial and woody tissues of Picea abies were used to generate the NorWood.conGenIE.org web resource, which facilitates exploration of the associated gene expression profiles and co-expression networks...

BACKGROUND: Licensed antiviral therapeutics and vaccines to protect against eastern equine encephalitis virus (EEEV) in humans currently do not exist. Animal models that faithfully recapitulate the clinical characteristics of human EEEV encephalitic disease, including fever, drowsiness, anorexia, and neurological signs such as seizures, are needed to satisfy requirements of the Food and Drug Administration (FDA) for clinical product licensing under the Animal Rule. METHODS: In an effort to meet this requirement, we estimated the median lethal dose and described the pathogenesis of aerosolized EEEV in the common marmoset (Callithrix jacchus)...

BACKGROUND: We compared brain cortical and subcortical gray matter volumes and cortical thickness between post-Fontan patients and healthy controls, and examined brain anatomical associations with operative and medical history characteristics. METHODS: Post-Fontan (n = 128 volumes; n = 115 thickness) and control subjects (n = 48 volumes; n = 45 thickness) underwent brain MRI at ages 10-19 years. Subcortical and cortical volumes and cortical thicknesses were measured for intergroup comparison...

OBJECTIVE: Kainic acid (KA) is a potent glutamate analog that is used to induce neurodegeneration and model temporal lobe epilepsy (TLE) in rodents. KA reliably induces severe, prolonged seizures, that is, convulsive status epilepticus (cSE), which is typically fatal without pharmacologic intervention. Although the use of KA to model human epilepsy has proven unquestionably valuable for >30 years, significant variability and mortality continue to confound results. These issues are probably the consequence of cSE, an all-or-nothing response that is inherently capricious and uncontrollable...

OBJECTIVE: The National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) was established in 2008 to improve outcomes of hypoplastic left heart syndrome (HLHS) during the interstage period. They evaluated changes in patient variables and practice variation between early and late eras. DESIGN: Data including demographic, operative, discharge, and follow-up variables from the first 100 patients (6/2008-1/2010) representing 18 centers were compared with the most recent 100 patients (1/2014-11/2014) from these same centers...

During the past decade, a hybrid procedure has emerged and dramatically evolved as an alternative stage I palliation to the conventional Norwood procedure in neonates with hypoplastic left heart syndrome (HLHS). The hybrid approach avoids the need for cardiopulmonary bypass (CPB) utilizing stenting of the arterial duct and bilateral pulmonary artery banding. Cerebral and coronary perfusion pressure is maintained, and the pulmonary vasculature is protected from higher systemic pressure. Elimination of risks associated with CPB gains vital time to stabilize the patient and correct coexisting noncardiac anomalies and allows growth in preparation for the later stages of the Fontan pathway...

INTRODUCTION: Androgens have been implicated in both male pattern baldness (MPB) and prostate cancer (PCa). We set out to prospectively determine if men with independently assessed MPB are at higher risk for PCa at biopsy and determine if any grade associations exist. METHODS: We prospectively enrolled 394 eligible patients presenting for prostate biopsy and independently determined their MPB pattern using the validated modified Norwood classification system (0: no balding; 1: frontal balding; 2: mild vertex balding; 3: moderate vertex balding; 4: sever vertex balding)...

The ability to quantify patient-specific hospital mortality risk before the Norwood procedure remains elusive. This study aimed to develop an accurate and clinically feasible score to assess the risk of hospital mortality in neonates undergoing the Norwood procedure. All patients (n = 549) in the publically available Pediatric Heart Network Single Ventricle Reconstruction trial database were included in the analysis. Patients were randomly divided into a derivation (75%) and validation (25%) cohort. Preoperative factors found to be associated with mortality upon univariable analysis (P < 0...

Among adults, living donor kidney transplant rates began declining in the United States after 2004 but whether a similar decline is occurring in the pediatric candidates has not been well studied. Share 35, a change in allocation rules implemented in October of 2005, may also have influenced rates of living donation. We sought to determine whether a decline in rates was occurring in pediatric candidates and whether the Share 35 program was the cause of the decline. All children listed for a kidney transplant or transplanted with a living donor without listing between 1996 and 2011 were identified in the United States (N=14 911) of which 6046 had received a living donor transplant during follow-up...

There are few data to guide aspirin therapy to prevent shunt thrombosis in infants. We aimed to determine if aspirin administered at conventional dosing in shunted infants resulted in ≥50% arachidonic acid (AA) inhibition in short and midterm follow-up using thromboelastography with platelet mapping (TEG-PM) and to describe bleeding and thrombotic events during follow-up. We performed a prospective observational study of infants on aspirin following Norwood procedure, aortopulmonary shunt alone, or cavopulmonary shunt surgery...

BACKGROUND: The development of recoarctation after the Norwood I procedure is a known complication in patients with hypoplastic left heart syndrome (HLHS). METHODS: We reviewed data on 194 consecutive patients with HLHS who underwent the Norwood I procedure between 2000 and 2015. All patients who survived until the second stage of the procedure were included. Recoarctation was defined by the need for intervention, either catheter based or surgical. The aim of our study was to determine if the patch material used for the initial arch reconstruction had an influence on the development of recoarctation...

BACKGROUND: Prescription drug abuse is epidemic in the United States (US). To help address the problem, most states operate prescription drug monitoring programs (PDMPs). PDMPs are designed to monitor and help control the distribution of controlled therapeutic medications and to assist prescribers and dispensers in making informed clinical decisions. To this end, PDMPs rely on timely and accurate data submission, as well as review of the data. Consequently, provider acceptance of these systems is essential to maximize their effectiveness...

BACKGROUND: Babies born with a functional single ventricle heart and systemic outflow tract obstruction may require a Norwood (NW) procedure as the first of three staged procedures to obtain a Fontan circulation. This procedure and the following treatment pathway are associated with significant mortality. Risk factors for the Norwood procedure and the subsequent pathway are not necessarily the same. To identify these factors within New Zealand, the collective experience with the Norwood procedure was examined...
