Patients with hypoplastic left heart syndrome undergo a series of operations to separate the pulmonary and systemic circulations. The first of at least 3 operations occurs in the newborn period, with a stage I palliation. The goal of stage I palliation is to provide pulmonary blood flow and create an unobstructed systemic outflow tract. Advances in surgical techniques and intraoperative and postoperative care have helped decrease morbidity and mortality for patients with hypoplastic left heart syndrome who have the stage I Norwood operation, but the patients continue to be at increased risk for hemodynamic collapse and adverse outcomes...

High-throughput screening (HTS) is the primary driver to current drug discovery efforts. New therapeutic agents that enter the market are a direct reflection of the structurally simple compounds that make up screening libraries. Unlike medically relevant natural products (e.g., morphine), small molecules currently being screened have low fraction sp3 character and few, if any, stereogenic centers. Although simple compounds have been useful in drugging certain biological targets (e.g., protein kinases), more sophisticated targets (e...

Extracorporeal cardiopulmonary resuscitation (ECPR) in children with cardiac arrest refractory to conventional cardiopulmonary resuscitation (CPR) has been reported with encouraging results. We reviewed outcomes of neonates with functional single ventricle (FSV) surviving post-cardiotomy ECPR after hospital discharge. Fifty-eight patients who required post-cardiotomy extracorporeal membrane oxygenation (ECMO) since the introduction of our ECPR protocol (January 2007-December 2011) were identified. Forty-one were neonates...

BACKGROUND: The stage 1 Norwood procedure and its variants represent the first step of palliation for hypoplastic left heart syndrome. Although appropriate postoperative thromboprophylaxis is integral, significant variance remains across institutional practices. The purpose of this systematic review is to estimate the incidence of thrombosis and thromboembolism following the Norwood or modified Blalock-Taussig shunt procedure and examine current thromboprophylaxis regimens. METHODS: Ovid MEDLINE and Embase were searched from January 2000 to June 2016 for primary studies explicitly reporting incidence of thrombosis, thromboembolism (strokes and pulmonary embolisms), or shunt occlusion in neonates, infants, and children undergoing the Norwood procedure or any variant...

BACKGROUND: Less than 2.7% of infants undergoing congenital heart disease operations have difficulty weaning from invasive mechanical ventilation. In such instances, clinicians may choose to perform tracheostomy. Limited literature has examined tracheostomy placement specifically in infants with hypoplastic left heart syndrome (HLHS). This study evaluated the risk factors for tracheostomy placement in infants with HLHS and examined the outcomes of these infants before their first hospital discharge...

Objective: Hair loss is a significant problem worldwide. The most common cause of hair loss in men is male androgenetic alopecia, male pattern baldness, which is primarily due to the presence of nonfunctional or dead hair follicles in the scalp. Hair follicular unit transplantation has been a widely used technique to transplant hair follicles into bald areas. Although follicular unit transplantation generally gives satisfactory hair transplantation, efforts have been made to further increase the efficacy of follicular unit transplantation in hair regeneration...

OBJECTIVE: Poor survival following surgical palliation for hypoplastic left heart syndrome (HLHS) raises the question of the need for a paradigm shift. This is the first human study to investigate the possibility of primary "in-series" palliation in neonates and infants with HLHS in an acute setting with the aid of 2 types of mechanical assist: superior vena cava (SVC)-to-pulmonary artery (PA) pump assist and SVC-to-right atrium (RA) oxygenation assist. METHODS: By rearranging the cannula sites and flow rates for modified ultrafiltration, 2 types of mechanically assisted bidirectional cavopulmonary shunt (BCPS) circulation were simulated for 20 minutes...

BACKGROUND: Conceptually the right ventricle (RV) is less suitable to support the Fontan circulation than the left (LV). After palliation of hypoplastic left heart syndrome (HLHS) involving aortic reconstruction during the Norwood procedure the RV is exposed to abnormal afterload. We studied ventricular function and ventriculo-arterial coupling in HLHS patients (RV) and Fontan patients with single LV morphology that did (LV+N) and did not (LV-N) undergo Norwood-type aortic reconstruction...

BACKGROUND: Cancer screening is below targets in Ontario, Canada. Our objective was to identify and quantify the barriers and facilitators for breast, cervical and colorectal cancer screening for under and never screened (UNS) residents living in Ontario between 2011 and 2013. METHODS: We used a multi-phased mixed methods study design. Results from thematic analysis of focus group discussions with health care providers and UNS community members were used to develop an on-line, province-wide, cross-sectional survey to estimate the prevalence of barriers and facilitators for the provincial population...

Neoaortic recoarctation is present in up to over one-third of patients having undergone the Norwood procedure for hypoplastic left heart syndrome. Some of these patients will require reintervention by catheterization or surgery through the time of the Glenn procedure. Echocardiography and catheterization are often utilized in this period to assess hemodynamics although no specific criteria have been identified to predict whether and when neoaortic arch reintervention will be needed. We sought to identify predictors, including but not limited to echocardiographic and catheterization gradients, to predict such intervention...

BACKGROUND: Specialist-led cancer follow-up is becoming increasingly expensive and is failing to meet many survivors' needs. Alternative models informed by survivors' preferences are urgently needed. It is unknown if follow-up preferences differ by cancer type. We conducted the first study to assess British cancer survivors' follow-up preferences, and the first anywhere to compare the preferences of survivors from different cancers. METHODS: A discrete choice experiment questionnaire was mailed to 1201 adults in Northeast Scotland surviving melanoma, breast, prostate or colorectal cancer...

Universally fatal only 4 decades ago, the progress in the 3-stage palliation of hypoplastic left heart syndrome and related single right ventricular lesions has drastically improved the outlook for these patients. Although the stage II operation (hemi-Fontan or bidirectional Glenn) and stage III Fontan procedure have evolved into relatively low-risk operations, the stage I Norwood procedure remains one of the highest-risk and costliest common operations performed in congenital heart surgery. Yet, despite this fact, experienced centers now report hospital survivals of >90% for the Norwood procedure...

We report a modified Norwood stage I procedure for tricuspid atresia, transposition of great arteries, and hypoplastic right aortic arch with complete vascular ring. In this technique, we applied dual arterial cannulation to avoid circulation arrest during neoaortic reconstruction, and also corrected the arch laterality during the Norwood stage I palliation procedure. Pulmonary flow was supplied by the Blalock-Taussig shunt. Postoperative imaging revealed the patent left neoaortic arch, and the vascular ring was relieved with a patent tracheobronchial tree...

Various classifications for male pattern baldness are mentioned in the literature. The 'Norwood's classification is the most commonly used but it has certain limitations. The new system has included 'three' extra features which were not mentioned in any other classification. It provides an opportunity to document the full and correct picture while documenting male pattern baldness. It also aids in assessing the treatment for various degrees of baldness.

INTRODUCTION: Injuries, including those resulting from violence, are a leading cause of death during pregnancy and the postpartum period. North Carolina, along with other states, has implemented surveillance systems to improve reporting of maternal deaths, but their ability to capture violent deaths is unknown. The purpose of this study was to quantify the improvement in ascertainment of pregnancy-associated suicides and homicides by linking data from the North Carolina Violent Death Reporting System (NC-VDRS) to traditional maternal mortality surveillance files...

Since the first successful intervention for hypoplastic left heart syndrome (HLHS) was undertaken by Norwood in 1983, there have been many advancements in the pre-, intra-, and postoperative care of these children for a diagnosis that just 25 years ago was almost certainly a fatal one. This paper aims to describe the most recent trends and perspectives on the treatment of HLHS. In particular, we will discuss the five current options for HLHS, including Norwood stage I as the beginning to 3-stage palliation, transplant, true hybrid, hybrid-bridge-to-Norwood, and compassionate care...

BACKGROUND: Antegrade cerebral perfusion (ACP) typically is used with deep hypothermia for cerebral protection during aortic arch reconstructions. The impact of ACP on cerebral oxygenation and serum creatinine at a more tepid 25 °C was studied in newborns and children. METHODS: Between 2010 and 2014, 61 newborns and children (<5 years old) underwent aortic arch reconstruction using moderate hypothermia (25.0±0.9 °C) with ACP and a pH-stat blood gas management strategy...
