Ischemic stroke has many devastating effects within the brain. At the cellular level, excitotoxicity has been a popular pharmacological target for therapeutics. To date, many clinical trials have been performed with drugs that target excitatory neurotransmitter receptors, such as NMDA receptor agonists. The results, however, have been lackluster. Most efforts to understand the impacts of excitotoxicity on the brain have focused primarily on neurons, and to a lesser degree, on gliocytes as cellular targets. Recent evidence suggests that oligodendrocytes (OLGs), the myelin-forming cells in the central nervous system, are damaged by ischemia in a manner completely different from that in neurons...

BACKGROUND: The role of supine positioning after acute stroke in improving cerebral blood flow and the countervailing risk of aspiration pneumonia have led to variation in head positioning in clinical practice. We wanted to determine whether outcomes in patients with acute ischemic stroke could be improved by positioning the patient to be lying flat (i.e., fully supine with the back horizontal and the face upwards) during treatment to increase cerebral perfusion. METHODS: In a pragmatic, cluster-randomized, crossover trial conducted in nine countries, we assigned 11,093 patients with acute stroke (85% of the strokes were ischemic) to receive care in either a lying-flat position or a sitting-up position with the head elevated to at least 30 degrees, according to the randomization assignment of the hospital to which they were admitted; the designated position was initiated soon after hospital admission and was maintained for 24 hours...

INTRODUCTION: The impact of choroid plexus with its blood-cerebrospinal fluid barrier in the ischemic stroke pathology is poorly explored. Transthyretin (TTR) is a protein synthesized in liver and just in choroid plexus. OBJECTIVES: The current study was designed to assess the prognostic value of serum TTR for functional outcome (at the time of hospital discharge) and long-term (one-year) overall mortality in ischemic stroke patients. PATIENTS AND METHODS: We conducted a prospective observational study...

Atrial fibrillation (AF) is a major risk factor for ischemic stroke and associated with a 5-fold higher risk of stroke. In this retrospective cohort study, the incidence of and risk factors for ischemic stroke in patients with AF were identified. All patients (≥30 years old) without previous stroke who were diagnosed with AF in 2007-2013 were selected from the National Health Insurance Service-National Sample Cohort. To identify factors that influenced ischemic stroke risk, Cox proportional hazard regression analysis was conducted...

High-on-treatment platelet reactivity (HPR) is associated with ischemic events in patients on antiplatelet therapy with a history of cardiovascular disease. On the other hand, recent data have associated sepsis with adverse cardiovascular events in patients admitted with bacteremia or respiratory infection. We aimed to assess P2Y12-mediated platelet reactivity (PR) during sepsis and recovery in patients under clopidogrel. This was a prospective observational study. Incoming patients presenting with signs/symptoms of sepsis already on a maintenance dose of clopidogrel of 75 mg qd for cardiovascular events were included in this study...

Objective Given its effects on lipid metabolism, the apolipoprotein A1-C3-A5 ( APOA1-C3-A5) gene cluster is thought to play an important role in ischemic stroke pathogenesis. Here, we evaluated whether the APOA1-C3-A5 cluster is associated with ischemic stroke in the northern Chinese Han population. Methods This case-control study analyzed 812 patients with ischemic stroke and 844 healthy controls with regard to four APOA1-C3-A5 cluster promoter single nucleotide polymorphisms (SNPs), rs670, rs2854116, rs2854117, and rs662799, using the SNaPshot Multiplex sequencing assay...

Insulin resistance often refers to a pathological condition in which cells fail to respond to the normal actions of insulin. Increasing literature has noted a critical role of insulin resistance in the pathogenesis of ischemic stroke. Insulin resistance plays an important role in the pathogenesis of ischemic stroke via enhancing advanced changes of atherosclerosis. A variety of literature indicates that insulin resistance enhances platelet adhesion, activation and aggregation which are conducive to the occurrence of ischemic stroke...

Ischemic strokes are major causes of death and disability. Searching for potential therapeutic strategies to prevent and treat stroke is necessary, given the increase in overall life expectancy. Epidemiological reports indicate that metformin is an oral antidiabetic medication that can reduce the incidence of ischemic events in patients with diabetes mellitus. Its mechanism of action has not been elucidated, but metformin pleiotropic effects involve actions in addition to glycemic control. AMPK activation has been described as one of the pharmacological mechanisms that explain the action of metformin and that lead to neuroprotective effects...

INTRODUCTION: Despite advances in stroke care, readmission rates for patients with ischemic stroke remain high. Although factors such as age, diabetes, and continuous use of antiplatelet agents have been found to predict readmission rates, the impact of after-hospital care has not been examined. METHODS: The present study reviewed the charts of 416 patients with acute ischemic stroke and recorded stroke-related comorbidities, neurology follow-up within 21 days, readmission at 0 to 30 days, readmission at 31 to 90 days, and any reasons for readmission...

BACKGROUND: Recent studies suggest that traumatic brain injury (TBI) is a risk factor for subsequent ischemic stroke, even years after the initial insult. The mechanisms of the association remain unclear. The presence of traumatic subarachnoid hemorrhage (tSAH) may mediate the effect of TBI on long-term stroke risk, as it has previously been linked to short-term vasospasm and delayed cerebral ischemia. METHODS: Using administrative claims data, we conducted a retrospective cohort study of acute care hospitalizations...

BACKGROUND AND PURPOSE: Poststroke functional outcome is critical to stroke survivors. We sought to determine whether adherence to current stroke performance measures is associated with better functional outcome 90 days after an ischemic stroke. METHODS: Utilizing the Brain Attack Surveillance in Corpus Christi cohort, we examined adherence to 7 ischemic stroke performance measures from February 2009 to June 2012. Adherence to the measures was analyzed in aggregate using a binary defect-free score and an opportunity score, representing the proportion of eligible measures met...

Moyamoya disease is a unique occlusive disease of the internal carotid artery(ICA)with moyamoya vessels that can lead to transient ischemic attacks and hemorrhagic stroke. When other inherited or acquired disorders and conditions occur in conjunction with moyamoya disease, the syndrome is known as quasi-moyamoya disease. We report the case of a 34-year-old woman with a past history of SAPHO(Synovitis-Acne-Pustulosis-Hyperostosis-Osteomyelitis)syndrome, who presented with arm weakness and headache. Magnetic resonance angiography revealed severe terminal stenosis of the left ICA with moyamoya vessels, and she was diagnosed as moyamoya disease associated with SAPHO syndrome...

Mitochondrial dysfunction is known as one of causative factors in ischemic stroke, leading to neuronal cell death. The present work was undertaken to investigate whether succinate induces neuron apoptosis by regulating mitochondrial morphology and function. In neurons, oxygen-glucose deprivation induced succinate accumulation due to the reversal of succinate dehydrogenase (SDH) activation, leading to mitochondrial fission. Kaempferol inhibited mitochondrial fission and maintained mitochondrial HK-II through activation of Akt, and thereby protected neurons from succinate-mediated ischemi injury...

BACKGROUND: Scalp acupuncture has shown a remarkable treatment efficacy on motor dysfunction in patients with stroke in China, especially the motor area of Jiao's scalp acupuncture, which is the most widely used treatment. However, previous studies have summarized that the clinical curative effect of acupuncture treatment for stroke remains uncertain. Meanwhile, no randomized controlled trials on Jiao's scalp acupuncture have been performed. The aim of this study is to evaluate the efficacy and safety of Jiao's scalp acupuncture for motor dysfunction in ischemic stroke...

Estimation of dietary sodium intake is problematic. The most accurate measure is average sodium excretion from multiple 24 hour urine collections, but such an approach is impractical. Using data from the Women's Health Initiative, Prentice and colleagues assessed the relationship of calibrated estimates of sodium and potassium excretion with cardiovascular outcomes. The calibrated estimates are a function of self-reported sodium/potassium ratio from a food frequency questionnaire, age, body mass index, race, supplement use, smoking status, education, income, and aspirin use...

Studies of sodium and potassium intake and cardiovascular disease incidence often rely on self-reported dietary data. Here self-reported intakes from postmenopausal women at 40 participating U.S. clinical centers are calibrated using 24-hour urinary excretion measures in Women's Health Initiative cohorts, with follow-up over 1993-2010. Hypertension incidence related positively to (calibrated) sodium intake and to the ratio of sodium-to-potassium. The sodium-to-potassium ratio was associated with cardiovascular disease incidence during a 12-year average follow-up period...
