END was defined as fall ≥1 points motor items Canadian...
To investigate whether molecular markers of inflammation and endothelial injury are associated with early growth intracerebral hemorrhage (ICH).In a multicenter prospective study, we determined concentrations interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), matrix metalloproteinase-9 (MMP-9), cellular fibronectin (c-Fn) in blood samples obtained on admission from 183 patients primary hemispheric ICH <12 hours' duration. Patients had neurological evaluation computed tomography...
Increased circulating endothelial progenitor cells (EPC) have been associated with a low cardiovascular risk and may be involved in cell regeneration. The present study was designed to evaluate the prognostic value of EPC acute ischemic stroke.Forty-eight patients first-ever nonlacunar stroke were prospectively included within 12 hours symptoms onset. Stroke severity evaluated by National Institutes Health Scale, functional outcome assessed at 3 months modified Rankin Scale (mRS). Infarct...
<b><i>Objective:</i></b> To evaluate the usefulness of a mismatch between severity acute clinical manifestations and diffusion-weighted imaging (DWI) lesion in predicting early stroke outcome infarct volume. <b><i>Methods:</i></b> One hundred sixty-six patients with hemispheric ischemic <12 hours’ duration were studied. The NIH Stroke Scale (NIHSS) score volume DWI measured on admission at 72 ± 12 hours. Infarct was T2-weighted or fluid-attenuated inversion recovery images day 30. Early...
Evidence is accumulating regarding the prognostic influence of hyperglycemia in patients with acute ischemic stroke. However, level associated poor outcome unknown. Our objectives were to establish capillary glucose threshold highest predictive accuracy and evaluate its hypothetical value influencing functional by adjusting for other well-known factors stroke.The authors conducted a multicenter, prospective, observational cohort study 476 stroke within less than 24 hours from onset....
Stroke triggers an intense inflammatory response that could be a consequence of Toll-like receptors (TLRs) activation. However, the clinical significance and therapeutic possibilities TLR in stroke is not completely clear. In this study, we analyze association between expression TLR2 TLR4, molecules endogenous ligands, outcome ischemic patients, test potential TLR2/TLR4 their ligands as targets. For purpose, included 110 patients with finding TLR4 are independently associated to poor...
<h3>Objective:</h3> We aimed to study endothelial function with biochemical and ultrasonographic markers its relation progenitor cells (EPCs) in patients migraine. <h3>Methods:</h3> performed a case-control including 47 episodic migraine (International Headache Society 2004 criteria) 23 control subjects. analyzed flow-mediated dilation (FMD) the dominant brachial artery, calcitonin gene−related peptide (CGRP), vascular growth factor (VEGF) levels by ELISA, nitric oxide stable metabolites...
Elevated plasma levels of cellular fibronectin (c-Fn) reflect vascular damage, so c-Fn might be a marker secondary bleeding risk in cerebral ischemia. We investigated whether high were associated with hemorrhagic transformation (HT) after treatment tissue plasminogen activator (tPA) patients acute stroke.Eighty-seven (mean age: 67+/-12) received tPA the ECASS II criteria time to infusion: 160+/-46 minutes; median NIHSS: 12). HT and hypodensity volume studied on computed tomography (CT)...
Space-occupying brain edema is a life-threatening complication in patients with large hemispheric stroke. The aim of the study was to determine whether molecular markers endothelial damage may help predict secondary and, secondly, identify who could benefit from aggressive therapies such as decompressive hemicraniectomy or hypothermia.We studied 40 consecutive malignant middle cerebral artery (MCA) infarction and 35 controls massive MCA infarctions <70 years age matched by stroke severity on...
We evaluated the mortality and morbidity of acute cerebral infarction as related to modifiable factors: glucose level, temperature, hematocrit, hemoglobin platelet count. studied 177 patients with in territory middle artery, admitted within 24 h stroke onset. Blood was drawn on admission temperature recorded every 2 h, selecting highest during 1st day. Patient follow-up lasted 6 months. Barthel Index Neurological Score were at days 1, 4, 7, 14, 21 3 A Glasgow Scale administered Forty-five...
The capacity of the blood enzyme glutamate oxaloacetate transaminase (GOT) to remove from brain by means degradation has been shown in experimental models be an efficient and novel neuroprotective tool against ischemic stroke; however, beneficial effects this should tested patients with stroke validate these results.

A current hypothesis for migraine suggests that neuroexcitatory amino acids may participate in the triggering of attacks. To investigate this possibility we measured glutamic and aspartic acid level plasma cerebrospinal fluid (CSF) patients with common classic during attacks, making comparisons controls suffering from stress. Plasma levels were lower than controls. CSF concentrations higher migraineurs Our results suggest an excess CNS possibly favoring a state neuronal hyperexcitability.
