BACKGROUND Children suffering from beta-thalassemia major require repeated blood transfusions which may be associated with dangers like iron overload and contraction of infections such as HIV, HCV, and HBsAg which ultimately curtail their life span. On the other hand, inadequate transfusions lead to severe anemia and general fatigue and debility. (More)
BACKGROUND The purpose of this study is to assess the impact of frailty index comprised of commonly used frailty metrics on outcomes following transcatheter aortic valve replacement (TAVR) outcomes, including mortality, length of stay, and discharge destination. METHODS AND RESULTS Retrospective data collection was performed for 342 consecutive patients(More)
BACKGROUND Lung transplantation is a widely accepted treatment for patients with end-stage lung disease related to idiopathic pulmonary fibrosis (IPF). However, there are conflicting data on whether double lung transplant (DLT) or single lung transplant (SLT) is the superior therapy in these patients. The purpose of this study was to determine whether(More)
BACKGROUND Previous studies have demonstrated that patients undergoing complex surgical procedures at high-volume centers have improved outcomes. The goal of this study was to determine if this volume-outcomes relationship persists at a national level among patients undergoing emergent open repair for thoracic aortic dissection. METHODS De-identified(More)
BACKGROUND There remains much controversy on impact of preoperative coronary artery disease (CAD) and necessity of preoperative coronary revascularization on postoperative outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS Data were collected retrospectively for 364 consecutive patients undergoing TAVR at Newark Beth(More)
BACKGROUND This study evaluated the effect of continuous-flow left ventricular assist device (CF-LVAD) duration on postoperative outcomes in heart transplant patients. METHODS United Network of Organ Sharing heart transplant follow-up data from 2005 to 2015 were obtained. Patients supported by CF-LVADs who subsequently underwent cardiac transplantation(More)
OBJECTIVE To determine the percentage of phenylketonuria (PKU) subjects using current treatment strategies whose phenylalanine (Phe) concentrations diverge from the UK target guidelines for PKU. RESEARCH DESIGN AND METHODS This retrospective, observational, chart review was conducted between 2004 and 2008 at three specialist PKU treatment centres in the(More)
Purpose: To examine the resource utilization of the endovascular approach for thoracic aortic aneurysm (TAA) repair, and quantify the incremental effect of complications on hospital costs and length of stay (LOS). Methods: De-identified patient-level claims data on a random sample of TAA repairs performed in the US from January 1st, 2008 to December 31st,(More)
BACKGROUND The impact of frailty status on TAVR outcomes in nonagenarians is unknown. The present study aims to investigate the impact of frailty status on procedural outcomes and overall survival in nonagenarians after TAVR. METHODS A frailty score (FS) was derived by using preoperative grip strength, gait speed, serum albumin, and daily activities.(More)
OBJECTIVES To evaluate the association between allocation of donor lungs by geographic sharing type (GST) and lung allocation score (LAS). METHODS UNOS data included lung transplant recipients between 5/4/05 and 09/30/15 (n = 17 416) grouped by GST of donor lungs: local, regional, or national. Recipients were stratified by LAS <50, 50-75, and >75.(More)
