OBJECTIVES: Central (aorta) and Sano (right ventricle)-to-pulmonary artery (PA) shunts, palliative operations for infants with complex heart defects, can develop life-threatening thrombosis. We employed computational fluid dynamics (CFD) to study pulsatile flow in these shunts, with the goal to identify haemodynamic characteristics conducive to thrombus formation. METHODS: CFD, using the finite volume method with cardiac catheterization data, and computer simulations, based on angiography, were employed to determine flow-velocity field, wall shear stress (WSS) profile and oscillatory shear index (OSI)...

Children in foster care have high rates of adverse childhood experiences and are at risk for mental health problems. These problems can be difficult to ameliorate, creating a need for rigorous intervention research. Previous research suggests that intervening with children in foster care can be challenging for several reasons, including the severity and complexity of their mental health problems, and challenges engaging this often transitory population in mental health services. The goal of this article was to systematically review the intervention research that has been conducted with children in foster care, and to identify future research directions...

For babies born with hypoplastic left heart syndrome, several open-heart surgeries are required. During Stage I, a Norwood procedure is performed to construct an appropriate circulation to both the systemic and the pulmonary arteries. The pulmonary arteries receive flow from the systemic circulation, often using a Blalock-Taussig (BT) shunt between the innominate artery and the right pulmonary artery. This procedure causes significantly disturbed flow in the pulmonary arteries. In this study, we use computational hemodynamic simulations to demonstrate its capacity for examining the properties of the flow through and near the BT shunt...

The use of a right ventricle-to-pulmonary artery conduit has re-emerged as a popular alternative to a systemic artery-to-pulmonary artery shunt in the Norwood procedure. Both proximal obstruction secondary to dynamic compression and distal obstruction at the anastomosis site with the pulmonary arteries are well described. In an effort to prevent complications, a technique where in the conduit is placed through the entire full thickness, or dunked, through the RV free wall has been described. We report a case of a patient with HLHS and positive lupus anticoagulant who developed recurrent conduit obstructions...

Rapid two-stage arterial switch operation (ASO) is very relevant as many patients of transposition of great arteries (TGA) present late to the hospital when primary switch either is not possible or carries a high risk of morbidity and mortality. Hence, other means apart from the traditional methods of left ventricle preparedness should be tried to help this category of patients, who are to undergo rapid two-stage ASO. We successfully used levosimendan and continuous positive airway pressure after 1st stage operation in a patient with dTGA and regressed ventricle, which helped in left ventricular preparedness, and the child underwent rapid two-stage ASO uneventfully...

In this study, hemodynamic performance of three novel shunt configurations that are considered for the surgical repair of tetralogy of Fallot (TOF) disease are investigated in detail. Clinical experience suggests that the shunt location, connecting angle, and its diameter can influence the post-operative physiology and the neurodevelopment of the neonatal patient. An experimentally validated second order computational fluid dynamics (CFD) solver and a parametric neonatal diseased great artery model that incorporates the ductus arteriosus (DA) and the full patient-specific circle of Willis (CoW) are employed...

The current study extends research on the impact of the Fostering Healthy Futures program (Taussig & Culhane, 2010), a 9-month mentoring and skills group preventive intervention for maltreated children, by examining whether the effect of Fostering Healthy Futures is moderated by children's baseline risk exposure (i.e., number of adverse childhood experiences). Participants included 156 racially and ethnically diverse children (ages 9-11, 50.7% female) recently placed in foster care due to maltreatment who were randomized to intervention or control conditions...

Absent pulmonary valve with an intact ventricular septum is a rare malformation. We report a case of absent pulmonary valve and intact ventricular septum with functional near-tricuspid atresia caused by pulmonary regurgitation. Initial palliation with main pulmonary artery ligation and bilateral pulmonary artery banding was performed at 1 day of age. More antegrade flow across the tricuspid valve was recognised postoperatively, resulting in a successful right ventricular outflow tract reconstruction by a hand-sewn bileaflet polytetrafluoroethylene valve and modified Blalock-Taussig shunt at 11 days of age...

PURPOSE: Neutropenic fever (NF) is an oncologic emergency and has resulted historically in inpatient management. The Multinational Association for Supportive Care in Cancer (MASCC) score can be used to identify patients with NF at a low risk of complications who can be managed safely as outpatients. Despite established guidelines supporting outpatient management of low-risk neutropenic fever (LRNF), provider awareness is low, and inpatient admission for intravenous antibiotics continues to be standard of care...

BACKGROUND: The arterial switch operation (ASO) has become the surgical approach of choice for transposition of the great arteries. The aim of this paper was to describe the outcomes in patients who underwent arterial switch operation and to analyze the predictors of in-hospital mortality and further need for reoperation at a single-center institution. We reviewed our 9-year experience with arterial switch operation (ASO) for transposition of the great arteries (TGA) or Taussig-Bing anomaly (TBA) to assess the early and midterm outcomes...

BACKGROUND: Homozygous familial hypercholesterolaemia is a genetic disorder characterised by substantially raised LDL cholesterol, reduced LDL receptor function, xanthomas, and cardiovascular disease before age 20 years. Conventional therapy is with statins, ezetimibe, and apheresis. We aimed to assess the long-term safety and efficacy of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor evolocumab in a subset of patients with homozygous familial hypercholesterolaemia enrolled in an open-label, non-randomised phase 3 trial...

BACKGROUND: Prospectively predicting response to intra-arterial therapy for hepatocellular carcinoma (HCC) is challenging. Neutrophil/lymphocyte ratio (NLR) is a serum biomarker that is associated with survival for multiple malignancies. It was hypothesized that increased NLR would be associated with early disease progression after intra-arterial therapy of HCC. METHODS: The outcomes of 86 treatment-naïve patients who had chemoembolization or radioembolization of HCC between July 2013-July 2014 were reviewed...

BACKGROUND: Children with body weight less than 2.5 kg who undergo the arterial switch operation (ASO) represent a challenging group. We sought to determine outcomes of patients with weight less than 2.5 kg at ASO at a single institution. METHODS: All patients who underwent an ASO with biventricular repair and weighed less than 2.5 kg at time of surgery were identified from the hospital database and reviewed retrospectively. RESULTS: From 1983 to 2014, 870 patients underwent an ASO with biventricular repair at our institution...
