Association between homocysteine and multivascular atherosclerosis in stroke-related vascular beds determined by three-dimensional magnetic resonance vessel wall imaging
This study investigated the relationship between homocysteine and multivascular atherosclerosis in stroke-related vascular beds using magnetic resonance imaging.MethodsPatients with recent ischemic cerebrovascular symptoms were enrolled and underwent three-dimensional magnetic resonance vessel wall imaging for intracranial arteries, extracranial carotid arteries and aortic arch. Traditional risk factors and homocysteine were measured. Presence of multivascular plaques defined as plaques in at least two stroke-related vascular beds on magnetic resonance imaging was determined. The relationship between homocysteine and characteristics of multivascular plaques was determined.ResultsOf 49 enrolled patients (mean age: 56.3 ± 13.8 years; 35 males), 23 had multivascular plaques. Homocysteine (odds ratio, 1.17; 95% confidence interval, 1.02–1.34; p = 0.022) and age (odds ratio, 1.71; 95% confidence interval, 1.22–2.41; p = 0.002) were significantly associated with presence of multivascular plaques. The adjusted associations remained significant (both p
Background: Three-dimensional, black-blood, contrast-enhanced, T1-weighted magnetic resonance imaging (3D-BB-ceT1-MRI) could play a role in detection of thrombi and symptomatic intracranial atherosclerotic stenosis. We investigated the role of 3D-BB-ceT1-MRI in patients with acute ischemic stroke in the posterior circulation, and compared our findings with those from susceptibility-weighted imaging (SWI). Materials and Methods: We retrospectively reviewed 3D-BB-ceT1-MRI for patients between January 2017 and August 2018 with acute ischemic symptoms in the posterior circulation.
Abstract Wake-up stroke (WUS) or ischemic stroke occurring during sleep accounts for 14%-29.6% of all ischemic strokes. Management of WUS is complicated by its narrow therapeutic time window and attributable risk factors, which can affect the safety and efficacy of administering intravenous (IV) tissue plasminogen activator (t-PA). This manuscript will review risk factors of WUS, with a focus on obstructive sleep apnea, potential mechanisms of WUS, and evaluate studies assessing safety and efficacy of IV t-PA treatment in WUS patients guided by neuroimaging to estimate time of symptom onset. The authors used PubMe...
This article discusses the various etiologies and mechanisms of this rare condition. It is unique because of the nerve's location and relation to other structures. PMID: 31511240 [PubMed - as supplied by publisher]
Objective: To determine whether the rich-club organization, essential for information transport in the human connectome, is an important biomarker of functional outcome after acute ischemic stroke (AIS).Methods: Consecutive AIS patients (N = 344) with acute brain magnetic resonance imaging (MRI) (
Abstract BACKGROUND: Previous studies have estimated that the risk of recurrent stroke was nearly 20% shortly after a transient ischemic attack (TIA) or minor stroke. A missing or hypoplastic (
Conclusion: The present case supports the scarce data underscoring the safety of intravenous thrombolysis for acute ischemic stroke in Fabry disease patients even when cerebral microbleeds are present.
CONCLUSIONS: Sixty percent of stroke survivors have a favorable cognitive outcome. Lower age and lower MTLA grade on MRI were associated with favorable outcome. PMID: 31461703 [PubMed - as supplied by publisher]
UP TO 40% of all ischemic strokes are considered cryptogenic, implying a stroke without a definitive etiology.1,2 With a dearth of evidence-guided treatment strategies, the literature surrounding cryptogenic stroke is highly variable and not well-standardized. Even though existing guidelines do not specify the exact testing required, the cryptogenic stroke evaluation includes a variety of imaging modalities (eg, echocardiography, angiography, magnetic resonance imaging, carotid ultrasound) and laboratory investigations (eg, genetic testing, hypercoagulable disorder panels, erythrocyte sedimentation rate).
AbstractBackgroundMales and females exhibit significant differences in metabolism and in brain ischemic stroke and different features of brain ischemic lesions are related to different health outcomes. It is critical to understand sex differences in their associations to optimize prevention and intervention for both sexes. We aimed to investigate the sex-specific association of metabolic risk factors with brain ischemic lesions by severity and location.MethodsFive thousand seven hundred ninety-one participants who underwent comprehensive health examinations between Jan. 1, 2017, and Dec. 31, 2017, were enrolled. Clinical a...
Photobiomodulation (PBM) therapy is a promising therapeutic approach for several pathologies, including stroke. The biological effects of PBM for the treatment of cerebral ischemia have been previously explored as neuroprotective strategy using different light sources, wavelengths and incident light powers. However, the capability of PBM as a novel an alternative therapy to stimulate the recovery of the injured neuronal tissue after ischemic stroke has been poorly explored. The aim of this study was to investigate the low-level light irradiation therapy by using Light Emitting Diodes (LEDs) as potential therapeutic stra...
