Assessing the influence of migraine on ischemic penumbra and on the prognosis of ischemic stroke: A prospective cohort study
CONCLUSION: Migraine is not associated with the absence of ischemic penumbra, the volume of the ischemic penumbra, or the stroke prognosis.PMID:36988078 | DOI:10.1111/head.14492

The effect of intensive statin therapy in non-symptomatic intracranial arteries: The STAMINA-MRI sub-study
ConclusionIntensive statin therapy produced a favorable morphological change in cerebral arteries of not only the target arterial segment but also non-symptomatic arterial segments. The change in cerebral arterial luminal diameter was influenced by the baseline SBP and was dependent on the topographic distribution of the cerebral arteries.Clinical Trial Registration: ClinicalTrials.gov, identifier NCT02458755.

Restricted access in the emergency department prevents MRI from being the workhorse for ischemic stroke care
We express our sincere gratitude to Wong et al. for their interest in our recent publication, “Is improved access to magnetic resonance imaging imperative for optimal ischemic stroke care?” [1]. We value the insights provided by the authors regarding the potential of magnetic resonance imaging (MRI) as the preferred imaging modality for acute ischemic stroke (AIS). Additionally, we appre ciate their valuable contribution on the utilization of short-sequence head MRI in addition to computed tomography (CT) for AIS evaluation at their center, which provides further evidence for the use of MRI in this context.

Diffusion-Weighted Magnetic Resonance Imaging Demonstrates White Matter Alterations in Watershed Regions in Children With Moyamoya Without Stroke or Silent Infarct
Moyamoya is a disease with progressive cerebral arterial stenosis leading to stroke and silent infarct. Diffusion-weighted magnetic resonance imaging (dMRI) studies show that adults with moyamoya have significantly lower fractional anisotropy (FA) and higher mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) compared with controls, which raises concern for unrecognized white matter injury. Children with moyamoya have significantly lower FA and higher MD in their white matter compared with controls.

Total Cerebral Small Vessel Disease Burden Predicts the Outcome of Acute Stroke Patients after Intra-Arterial Thrombectomy
Conclusions: The total cSVD burden score was independently associated with the clinical outcomes of AIS patients after IAT treatment and it may be a reliable predictor for poor outcomes of AIS patients after IAT treatment.Cerebrovasc Dis

A Novel Rat Model of Embolic Cerebral Ischemia Using a Cell-Implantable Radiopaque Hydrogel Microfiber
We present a novel rat model of focal infarct restricted to the middle cerebral artery territory using a radiopaque hydrogel microfiber positioned under fluoroscopic guidance. By comparing the use of stem cell-containing versus non-containing fibers in this stroke model, it would be possible to determine the efficacy of"pure" cell transplantation in treating stroke.

Exome-based gene panel analysis in a cohort of acute juvenile ischemic stroke patients:relevance of NOTCH3 and GLA variants
ConclusionGenetic screening for Fabry ’s disease in cardioembolic and lacunar stroke as well as CADASIL in lacunar stroke might be beneficial in routine medical work-up of acute juvenile ischemic stroke.

Rare RNF213 variant in adolescent with moyamoya disease
CONCLUSION: To our knowledge, the p.(Arg406262Gln) variant has been reported in three Japanese moyamoya disease patients and one European. Therefore, our patient was the second European moyamoya disease patient with this variant identified.PMID:36843178 | DOI:10.33588/rn.7605.2021392
