Recurrent Hemispheric Stroke Syndromes in Symptomatic Atherosclerotic Internal Carotid Artery Occlusions: The Carotid Occlusion Surgery Study Randomized Trial.

Background: There are limited data on outcomes of extracranial-intracranial (EC-IC) bypass in patients with recurrent hemispheric syndromes due to atherosclerotic internal carotid artery occlusion (AICAO).

Objective: To compare clinical outcomes and efficacy of EC-IC bypass surgery in patients with and without recurrent hemispheric syndromes associated with AICAO in the Carotid Occlusion Surgery Study (COSS).

Methods: In patients enrolled in the COSS trial, we compared baseline characteristics and clinical outcomes for participants with (rHEMI+) and without recurrent hemispheric ischemia (rHEMI-) prior to randomization into surgical vs medical groups.

Hemicraniectomy versus Conservative Treatment in Large Hemispheric Ischemic Stroke Patients: A Meta-analysis of Randomized Controlled Trials.

Background: Several small trials have inconclusively evaluated the effect of hemicraniectomy in reducing death and disability in acute ischemic stroke patients with large hemispheric infarctions. We compared the effects of hemicraniectomy on death and disability with conservative treatment in patients with large hemispheric infarctions.

Methods: We calculated pooled odds ratios (ORs) and 95% confidence intervals (CIs) using random-effects models from 7 randomized trials that compared hemicraniectomy with conservative treatment in acute ischemic stroke patients.

Aortic arch calcification, procedural times, and outcomes of endovascular treatment in patients with acute ischemic stroke.

Objective: To determine the frequency of aortic arch calcification and it's relationship with procedural times, angiographic recanalization, and discharge outcomes in acute ischemic stroke patients undergoing endovascular treatment.

Methods: The thoracic component of computed tomographic (CT) angiogram were reviewed by an independent reviewer to determine presence of any calcification; and the severity of calcification was graded as follows: mild, single small calcifications; moderate, multiple small calcifications; or severe, one or more large calcifications.

Results: Aortic arch calcification was present in 120 (62.

Vitamin D deficiency and osteoporosis in stroke survivors: an analysis of National Health and Nutritional Examination Survey (NHANES).

Background And Purpose: An inverse association between 25-hydroxyvitamin D (25[OH]D) levels and stroke was emphasized in recent studies. Our objective was to determine the rate of Vitamin D deficiency and risk of associated osteoporosis among stroke survivors in a nationally representative population.

Methods: Participants from the National Health and Nutritional Examination Survey (NHANES) from 2001 to 2006 were included.

Rates and outcomes of neurosurgical treatment for postthrombolytic intracerebral hemorrhage in patients with acute ischemic stroke.

Objective: Postthrombolytic intracerebral hemorrhage (ICH) is an infrequent occurrence in patients with acute ischemic stroke. There is controversy surrounding the value of neurosurgical treatment of symptomatic hematomas in these patients and whether availability of neurosurgical treatment is a necessary prerequisite for administration of thrombolytic agents. We report the frequency and outcomes of patients who undergo craniotomy for postthrombolytic ICH.

Theoretical accuracy of model-based shape matching for measuring natural knee kinematics with single-plane fluoroscopy.

Quantification of knee motion under dynamic, in vivo loaded conditions is necessary to understand how knee kinematics influence joint injury, disease, and rehabilitation. Though recent studies have measured three-dimensional knee kinematics by matching geometric bone models to single-plane fluoroscopic images, factors limiting the accuracy of this approach have not been thoroughly investigated. This study used a three-step computational approach to evaluate theoretical accuracy limitations due to the shape matching process alone.
