OBJECTIVES To determine the prevalence and clinical features associated with micrographia in Parkinson's Disease (PD). SETTING This study was conducted at a Movement Disorders clinic located in a Veteran Administration Hospital. PARTICIPANTS PD subjects were included only if they satisfied UK Parkinson's Disease Society criteria for diagnosis. Subjects(More)
BACKGROUND Quality of life (QOL) outcomes become critical for survivors of head and neck cancer. Most QOL studies were based on <5-year outcomes and very few addressed >5-year outcomes. This study focused late complications and >5-year outcomes and also compared the 2 standard treatments. METHODS The long-term problems were identified through mail(More)
Coat-color proportions and patterns in mice are used as assays for many processes such as transgene expression, chimerism, and epigenetics. In many studies, coat-color readouts are estimated from subjective scoring of individual mice. Here we show a method by which mouse coat color is quantified as the proportion of coat shown in one or more digital images.(More)
The amniotic fluid volume (AFV) is regulated by several systems, including the in-tramembranous pathway, fetal production (fetal urine and lung fluid) and uptake (fetal swallowing), and the balance of fluid movement via osmotic gradients. The normal AFV across gestation has not been clearly defined; consequently, abnormal volumes are also poorly defined.(More)
BACKGROUND/AIMS To examine the relationship of the amniotic fluid index (AFI) and single deepest pocket (SDP) with an AFV as modelled by Brace or Magann. METHODS AFI and SDP were evaluated for their correlation with an actual AFV using the Spearman correlation coefficient. RESULTS 482 AFI and 468 SDP pregnancies were evaluated. There was a significant(More)
To develop uniform and reliable reference ranges for amniotic fluid volume (AFV) across gestation in normal singleton pregnancies using quantile regression (QR). An analysis of true AFVs determined by dye-dilution techniques or by direct measurement at cesarean delivery in normal singleton pregnancies. AFV centiles were established by QR, a flexible(More)
OBJECTIVE The purpose of this study was to investigate the effects of orally administered over-the-counter omega-3 (n-3) fatty acid supplements on primary patency of polytetrafluoroethylene (PTFE) grafts. DESIGN This study was conducted with a triple-blind, permuted-block, randomized, placebo-controlled experimental design. SETTING Dialysis clinics with(More)
PURPOSE To investigate the likelihood of resolution of idiopathic polyhydramnios in pregnant women and compare outcomes between resolved and persistent cases. METHODS One hundred and sixty-three women with idiopathic polyhydramnios who delivered at two medical centers during a 3 year period (January 2012-January 2015) were included in the study. Exclusion(More)
OBJECTIVE To examine the factors associated with delivery of preterm infants at neonatal intensive care unit (NICU) hospitals in Arkansas during the period 2001-2006, with a focus on the impact of a Medicaid supported intervention, Antenatal and Neonatal Guidelines, Education, and Learning System (ANGELS), that expanded the consulting capacity of the(More)
To estimate a classifier’s error in predicting future observations, bootstrap methods have been proposed as reduced-variation alternatives to traditional cross-validation (CV) methods based on sampling without replacement. Monte Carlo (MC) simulation studies aimed at estimating the true misclassification error conditional on the training set are commonly(More)
