BACKGROUND AND PURPOSE We sought to build models that address questions of interest to patients and families by predicting short- and long-term mortality and functional outcome after ischemic stroke, while allowing for risk restratification as comorbid events accumulate. METHODS A cohort of 451 ischemic stroke subjects in 1999 were interviewed during(More)
BACKGROUND Anti-epileptic drugs are commonly used for seizure prophylaxis after neurological injury. We performed a study comparing intravenous (IV) levetiracetam (LEV) to IV phenytoin (PHT) for seizure prophylaxis after neurological injury. METHODS In this prospective, single-center, randomized, single-blinded comparative trial of LEV versus PHT (2:1(More)
BACKGROUND AND PURPOSE Biochemical markers of acute neuronal injury may aid in the diagnosis and management of acute ischemic stroke. Serum samples from the National Institute for Neurological Disorders and Stroke (NINDS) recombinant tissue plasminogen activator Stroke Study were analyzed for the presence of 4 biochemical markers of neuronal, glial, and(More)
Functional magnetic resonance imaging (fMRI) has the potential to replace the intracarotid amobarbital procedure (IAP) in presurgical evaluation of patients with epilepsy. In this study, we compared fMRI verb generation (VG) and semantic decision/tone decision (SDTD) tasks and the IAP in their ability to localize language functions in patients with epilepsy(More)
BACKGROUND AND PURPOSE Timely access to medical treatment is critical for patients with acute stroke because acute therapies must be given very quickly after symptom onset. We examined the effect of socioeconomic status on prehospital delays in stroke and transient ischemic attack (TIA) patients within a large, biracial population. METHODS By screening(More)
BACKGROUND AND PURPOSE Early hematoma expansion in spontaneous intracerebral hemorrhage (ICH) is associated with worse clinical outcome. We hypothesized that hemodynamic parameters are associated with the increase in hematoma volume owing to their relationship to blood vessel wall stresses. METHODS We performed a post hoc analysis of clinical and computed(More)
Although red blood cell (RBC) life span is a known determinant of percentage hemoglobin A1c (HbA1c), its variation has been considered insufficient to affect clinical decisions in hematologically normal persons. However, an unexplained discordance between HbA1c and other measures of glycemic control can be observed that could be, in part, the result of(More)
5 OBJECTIVE — HbA 1c (A1C) is substantially determined by genetic factors not shared in common with glucose. Fractions of the variance in A1C, the glycation gap (GG; previously called the glycosylation gap) and the hemoglobin glycosylation index, correlate with diabetes complications. We therefore tested whether GG (measured A1C Ϫ A1C predicted from(More)
OBJECTIVES To assist occupational health professionals to interpret the results of standardised tests for components of the hand-arm vibration syndrome by presenting data for healthy subjects and identifying the effects of some of the confounding variables. METHOD Thermal thresholds, vibrotactile thresholds, the finger skin temperature (FST) response to(More)
OBJECTIVE To determine whether interindividual heterogeneity in the erythrocyte (red blood cell [RBC]) transmembrane glucose gradient might explain discordances between A1C and glycemic control based on measured fructosamine. RESEARCH DESIGN AND METHODS We modeled the relationship between plasma glucose and RBC glucose as the concentration distribution(More)
