PURPOSE This study investigated the association of COPD and postoperative cardiac arrhythmias, specifically supraventricular tachycardia (SVT), as well as mortality in patients undergoing pulmonary resection for non-small cell lung cancer (NSCLC). METHODS A retrospective chart review of 244 patients who had undergone lung resection for NSCLC at Indiana(More)
BACKGROUND In the mega-diverse insect order Lepidoptera (butterflies and moths; 165,000 described species), deeper relationships are little understood within the clade Ditrysia, to which 98% of the species belong. To begin addressing this problem, we tested the ability of five protein-coding nuclear genes (6.7 kb total), and character subsets therein, to(More)
BACKGROUND Higher-level relationships within the Lepidoptera, and particularly within the species-rich subclade Ditrysia, are generally not well understood, although recent studies have yielded progress. We present the most comprehensive molecular analysis of lepidopteran phylogeny to date, focusing on relationships among superfamilies. METHODOLOGY(More)
This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n = 23; USA, n(More)
BACKGROUND The availability of an ideal prosthesis for aortic valve replacement (AVR) in children remains controversial due to an early degeneration of xenografts and the potential risks related to anticoagulation with mechanical prostheses. This has led many surgeons to the Ross procedure. This study outlines the evolution of our 30-year experience with(More)
The methods of managing 32 patients sustaining caustic injuries to the esophagus are assessed. Treatment of these patients must be individualized according to the type of caustic ingested, the degree of burn and other clinical signs. While an aggressive approach is favored for second and third-degree burns in the form of early esophago-gastrectomy with(More)
BACKGROUND The Extension for Community Healthcare Outcomes (ECHO) model was developed to improve access to care for underserved populations with complex health problems such as hepatitis C virus (HCV) infection. With the use of video-conferencing technology, the ECHO program trains primary care providers to treat complex diseases. METHODS We conducted a(More)
BACKGROUND The purpose of this report is to compare the outcome of the extracardiac (EC) with the lateral tunnel (LT) Fontan. METHODS From January 1990 to October 2004, the Fontan operation was performed in 162 patients, of which 49 were EC and 113 were LT. Cardiac morphology and ventricular dominance were similar, except EC patients were older and had a(More)
OBJECTIVE We evaluated focused training in coronary artery anastomosis with a porcine heart model and portable task station. METHODS At "Boot Camp," 33 first-year cardiothoracic surgical residents participated in 4-hour coronary anastomosis sessions (6-7 attending surgeons per group of 8-9 residents). At beginning, midpoint, and session end, anastomosis(More)
BACKGROUND Management of pulmonary hypertension, a potentially fatal complication of operations to correct congenital heart disease, has evolved through the last 15 years. Monitoring of pulmonary arterial pressure and mixed venous saturation became available, and prophylactic use of alpha-blockers and other vasodilators increased. This study examines risk(More)
