Establishing a pediatric acute stroke protocol: experience of a new pediatric stroke program and predictors of acute stroke
ConclusionA trainee developed and initiated pediatric acute stroke protocol quickly implemented a hospital wide change in management that led to rapid diagnosis and triage of pediatric stroke and suspected stroke. No additional personnel or resources were needed for this change, and we encourage other hospitals and emergency departments to implement similar systems. Additionally, hemiparesis and altered mental status were predictors of stroke for pediatric acute stroke activation in our Bayesian statistical analysis. However credible intervals were wide due to the small sample size. Further multicenter data collection coul...

A comparative study of seizures in arterial and venous stroke
Conclusion CVST results in more frequent and early seizures whereas in arterial stroke late seizures are common. Post stroke seizures in ischemic stroke were predicted by carotid territory infarction and venous stroke by parenchymal involvement.

Effectiveness and neural mechanisms of home-based telerehabilitation in patients with stroke based on fMRI and DTI: A study protocol for a randomized controlled trial
This study is designed to determine the efficacy and explore the mechanism of motor recovery after home-based telerehabilitation in stroke patients with motor deficits.Methods/Design:In a single-blinded randomized controlled pilot study, patients with acute subcortical stroke (n = 40) are assigned to receive home-based telerehabilitation or conventional rehabilitation. Task-based or resting-state functional magnetic resonance imaging (rs-fMRI), diffusion tensor imaging (DTI), and Fugl–Meyer assessment (FMA) score will acquired before and after rehabilitation. Activation volume of bilateral primary motor (M1), supplem...

Stroke Mimics and Chameleons from the Radiological Viewpoint of Glioma Diagnosis.
This study enrolled 214 patients who underwent tumor resection for suspected glioma. Clinical characteristics and radiological findings of the patients were compared between the masquerade findings group, which was further divided into two groups: the stroke chameleons and stroke mimics according to their final diagnosis, and the intelligible findings group.Stroke chameleons and stroke mimics were significantly higher in age and smaller in lesion size than the intelligible findings group. In the multivariate analysis, the predictive factor of the masquerade finding group was higher age and smaller size. Stroke mimics group...

Magnetic Resonance Imaging and Gait Analysis Indicate Similar Outcomes Between Yucatan and Landrace Porcine Ischemic Stroke Models
The objective of this study was to characterize brain anatomy and assess spatiotemporal gait parameters in Yucatan (YC) and Landrace (LR) pigs pre- and post-stroke using magnetic resonance imaging (MRI) and gait analysis, respectively. Ischemic stroke was induced via permanent middle cerebral artery occlusion (MCAO). MRI was performed pre-stroke and 1-day post-stroke. Structural and diffusion-tensor sequences were performed at both timepoints and analyzed for cerebral characteristics, lesion diffusivity, and white matter changes. Spatiotemporal and relative pressure gait measurements were collected pre- and 2-days post-str...

Early brain imaging predictors of post-stroke spasticity
CONCLUSION: Lesions involving motor network areas are considered to be a precondition of post-stroke spasticity. There is, however, a low risk of developing post-stroke spasticity with < 0.5 cm3 volumes of supratentorial brain lesions involving motor network areas. Larger volume brain lesions involving motor network areas, e.g. > 3 cm3, were significantly more common in patients with post-stroke spasticity. Pure cortical lesions has no risk of post-stroke spasticity in stroke survivors.PMID:33616193 | DOI:10.2340/16501977-2803

Identification of acute stroke using quantified brain electrical activity.
CONCLUSIONS: Despite a small population and the use of a classifier without the benefit of training on a stroke population, these data suggest that a rapidly acquired, easy-to-use system to assess brain electrical activity at the time of evaluation of acute stroke could be a valuable adjunct to current clinical practice.

Can we distinguish stroke and stroke mimics via red cell distribution width in young patients?
CONCLUSIONS: Red cell distribution width is a promising, rapid, easy and inexpensive parameter to distinguish young stroke from stroke mimics (such as epilepsy and MS) in young patients.

Magnetic resonance perfusion imaging provides a significant tool for the identification of cardioembolic stroke.
In conclusion, perfusion MRI could be a reliable tool to identify cardioembolic stroke with its lower collateral. This is important as it could be used to reveal the exact mechanism and provide supportive evidence to classify a stroke.

Factors that influence the severity of post-stroke depression.
CONCLUSION: The location of the stroke and the NIHSS score could be related to the severity of post-stroke depression. Abbreviations: NIHSS = The National Institutes of Health Stroke Scale; QQL = Quality of life Scale; BDI = Beck Depression Inventory; MMSE = Mini-Mental State Examination; PSD = Post-stroke depression; MRI = Magnetic resonance imaging.

BOLD fMRI signal in stroke patients and its importance for prognosis in the subacute disease period – Preliminary report
Conclusion There are differences observed in the activation areas of the cerebral cortex both in the stroke and non-stroke hemispheres of the brain in stroke patients. More than half of the patients with hemispheric stroke but all with good outcome showed cerebellar activation. There was no clear correlation between the cortical activation pattern and the neurological status on the first day of stroke. There is probable positive correlation between the size of BOLD-signal in fMRI, young age, activation of supplementary motor area in stroke hemisphere and good functional status of patients in the subacute period of stroke.

Sex differences and risk factors in recurrent ischemic stroke
ConclusionHypertension and dyslipidemia were significant risk factors of recurrent ischemic stroke in both genders. Smoking and alcohol drinking were significant risk factors associated with ischemic stroke recurrence in males. Therefore, smoking cessation and alcohol abstinence are recommended after the first stroke to prevent recurrent ischemic stroke especially for males. Diabetes was a significant risk factor of ischemic stroke recurrence in females. More extensive studies are needed to understand the causal relationship of each factors with ischemic stroke recurrence according to sex differences and specification of p...
