UNLABELLED Biliary atresia (BA) is a progressive fibroinflammatory obstruction of extrahepatic bile ducts that presents as neonatal cholestasis. Due to the overlap in clinical, biochemical, and histological features with other causes of cholestasis, the diagnosis requires an intraoperative cholangiogram. Thus, we determined whether diseased livers express a(More)
The potential of successful cognitive radio networks operating in TV White Spaces (and other future bands re-allocated for unlicensed operation) has led to significant upsurge of interest in their design optimization - particularly those that are cross-layer in nature, involving both MAC protocols as well as physical layer aspects such as channel sensing.(More)
Exposure assessment for elemental components of particulate matter (PM) using land use modeling is a complex problem due to the high spatial and temporal variations in pollutant concentrations at the local scale. Land use regression (LUR) models may fail to capture complex interactions and non-linear relationships between pollutant concentrations and land(More)
When defining allergic outcomes in epidemiology studies, results of the skin prick test (SPT) panel are often dichotomized as positive/negative or categorized based on the number of positive responses. Item response theory (IRT) models, however, may prove to be a better alternative with the ability to generate scores that account for both type and number of(More)
BACKGROUND CONTEXT Risk factors for surgical site infection (SSI) in children derived from the studies in the adult population are potentially misleading because of differences in pathophysiology and management. PURPOSE This systematic review addresses the key question: What are the risk factors for SSI in pediatric patients undergoing scoliosis surgery?(More)
OBJECTIVE To describe the survival of patients with primary small cell carcinoma (SCC) of the prostate and assess prognostic factors based on a large population sample. PATIENTS AND METHODS A total of 241 cases of SCC of the prostate were reported to the Surveillance, Epidemiology, and End Results (SEER) registries from 1973 to 2003 of which 191 cases(More)
Introducing mesenchymal stem cell (MSC)-seeded collagen constructs into load-protected wound sites in the rabbit patellar and Achilles tendons significantly improves their repair outcome compared to natural healing of the unfilled defect. However, these constructs would not be acceptable alternatives for repairing complete tendon ruptures because they lack(More)
BACKGROUND The epidemiology of aminoglycoside-associated acute kidney injury (AG-AKI) has not been well described in pediatric patients with cystic fibrosis (CF). We aimed to assess the impact of daily serum creatinine (SCr) measurement on detection of AG-AKI at our institution. METHODS We examined a cohort of hospitalized patients with CF who received an(More)
In vitro mechanical stimulation has been reported to induce cell alignment and increase cellular proliferation and collagen synthesis. Our group has previously reported that in vitro mechanical stimulation of tissue-engineered tendon constructs significantly increases construct stiffness and repair biomechanics after surgery. However, these studies used a(More)
Young age at portoenterostomy has been linked to improved outcome in biliary atresia, but pre-existing biological factors may influence the rate of disease progression. In this study, we aimed to determine whether molecular profiling of the liver identifies stages of disease at diagnosis. We examined liver biopsies from 47 infants with biliary atresia(More)
