Altered phalanx force direction during power grip following stroke.
This study characterized stroke survivors' static power grip during 100 and 50 % maximum grip. Each phalanx force angular deviation from the normal direction and its contribution to total normal force was compared for 11 stroke survivors and 11 age-matched controls. Muscle activities and skin coefficient of friction were additionally compared for another 20 stroke and 13 age-matched control subjects. The main finding was that stroke survivors gripped with a 34 % greater phalanx force angular deviation of 19° ± 2° compared to controls of 14° ± 1° (p < .05). Stroke survivors' phalanx force angular deviation ...

Blocking Sympathetic Nervous System Reverses Partially Stroke-Induced Immunosuppression but does not Aggravate Functional Outcome After Experimental Stroke in Rats.
This study suggests that pharmacological SNS inhibition dose not aggravate functional outcome after stroke. Stroke-induced immunosuppression may be involved in the SNS-β-arrestin2-NF-κB pathway. PMID: 27059792 [PubMed - as supplied by publisher]

Sex differences in neuroinflammation and neuroprotection in ischemic stroke
Stroke is not only a leading cause of mortality and morbidity worldwide it also disproportionally affects women. There are currently over 500,000 more women stroke survivors in the US than men, and elderly women bear the brunt of stroke‐related disability. Stroke has dropped to the fifth leading cause of death in men, but remains the third in women. This review discusses sex differences in common stroke risk factors, the efficacy of stroke prevention therapies, acute treatment responses, and post‐stroke recovery in clinical populations. Women have an increased lifetime risk of stroke compared to men, largely due to a s...

Effect of Visual Art School–Based Stroke Intervention for Middle School Students
ABSTRACT: Background: Community stroke awareness initiatives have traditionally been used to expand knowledge of stroke signs and risk factors to high-risk adult populations. Here, we use a novel unfettered, visual art–based approach for an elementary school initiative to raise stroke awareness. Methods: Seventh graders in a middle school art class received stroke awareness training during the course of the 2015 to 2016 school year through their teacher in the visual arts class. In turn, they used this training to develop their own artistic interpretations of key stroke awareness concepts via project-based learning and t...

Early administration of pyrrolidine dithiocarbamate extends the therapeutic time window of tissue plasminogen activator in a male rat model of embolic stroke
Abstract Tissue plasminogen activator (tPA) is used in fewer than 4% of patients after ischemic stroke because of its narrow therapeutic time window. We tested whether pyrrolidine dithiocarbamate (PDTC), a drug with multiple mechanisms to provide neuroprotection, can be used to extend the therapeutic time window of tPA. Three‐month‐old male Sprague‐Dawley rats were subjected to embolic stroke in the area supplied by the right middle cerebral artery. tPA at 10 mg/kg was given intravenously 4 h after the onset of stroke. PDTC at 50 mg/kg was given via gastric gavage at 30 min or 4 h after the onset of stroke....

Quantitative and Qualitative EEG as a Prediction Tool for Outcome and Complications in Acute Stroke Patients.
Abstract Currently, the relevance of EEG measurements in acute stroke patients is considered low in clinical practice. However, recent studies on the predictive value of EEG measurements after stroke for various outcomes may increase the role of EEG in patients with stroke. We aimed to review the current literature on the utility of EEG measurements after stroke as a tool to predict outcome and complications, focusing on studies in which the EEG measurement was performed in the acute phase after the event and in which long-term outcome measures were reported. In our literature review, we identified 4 different out...

Micro RNA 181c-5p: a promising target for post-stroke recovery in socially isolated mice
Publication date: Available online 10 November 2019Source: Neuroscience LettersAuthor(s): Maria Antony, Victoria Scranton, Pranay Srivastava, Rajkumar VermaAbstractDysregulation of microRNAs (miRNAs) has been tied to several neurological disorders, including ischemic stroke. It has also been established that social environments can modulate miRNA profiles. We have previously shown that post-stroke social isolation (SI) is linked to poor stroke outcomes and that miR-181c-5p emerged as one of few lead miRNAs that was downregulated in both stroke and SI. Therefore, in this study we examined the potential role of miR-181c-5p m...

Integrated Gait Triggered Mixed Reality and Neurophysiological Monitoring as a Framework for Next-Generation Ambulatory Stroke Rehabilitation
Brain stroke affects millions of people in the world every year, with 50 to 60 percent of stroke survivors suffering from functional disabilities, for which early and sustained post-stroke rehabilitation is highly recommended. However, approximately one third of stroke patients do not receive early in hospital rehabilitation programs due to insufficient medical facilities or lack of motivation. Gait triggered mixed reality (GTMR) is a cognitive-motor dual task with multisensory feedback tailored for lower-limb post-stroke rehabilitation, which we propose as a potential method for addressing these rehabilitation challenges....

Regulation of DAPK1 by Natural Products: An Important Target in Treatment of Stroke
Neurochem Res. 2022 Jun 8. doi: 10.1007/s11064-022-03628-7. Online ahead of print.ABSTRACTStroke is a sudden neurological disorder that occurs due to impaired blood flow to an area of the brain. Stroke can be caused by the blockage or rupture of a blood vessel in the brain, called ischemic stroke and hemorrhagic stroke, respectively. Stroke is more common in men than women. Atrial fibrillation, hypertension, kidney disease, high cholesterol and lipids, genetic predisposition, inactivity, poor nutrition, diabetes mellitus, family history and smoking are factors that increase the risk of stroke. Restoring blood flow by repos...

Navigating Antiplatelet Treatment Options for Stroke: Evidence-Based and Pragmatic Strategies
AbstractPurpose of ReviewThe benefit of using antiplatelet monotherapy in acute ischemic stroke and secondary stroke prevention is well established. In the last few years, several large randomized trials showed that the use of short-term dual antiplatelet therapy in particular stroke subtypes may reduce the risk of recurrent ischemic events. The aim of this article is to provide a critical analysis of the current evidence and recommendations for the use of antiplatelet agents for stroke prevention.Recent FindingsLong-term therapy with aspirin, clopidogrel, or aspirin plus extended-release dipyridamole is recommended for se...
