Background: Cerebral amyloid angiopathy (CAA) is characterized by amyloid-β (Aβ) deposition in cerebral vessels, leading to lobar cerebral microbleeds (CMB) and intracerebral hemorrhages (ICH). Apolipoprotein J (ApoJ) is a multifunctional chaperone related to Aβ aggregation and clearance. Our study investigated the vascular impact of chronic recombinant human Apolipoprotein J (rhApoJ) treatment in a transgenic mouse model of β-amyloidosis with prominent CAA.

Background And Objectives: Whether the outcome of patients with spontaneous intracerebral hemorrhage (ICH) differs depending on the type of hospital where they are admitted is uncertain. The objective of this study was to determine influence of hospital type at admission (telestroke center [TSC], primary stroke center [PSC], or comprehensive stroke center [CSC]) on outcome for patients with ICH. We hypothesized that outcomes may be better for patients admitted to a CSC.

Article Synopsis
  • The study investigates the effectiveness of endovascular treatment (EVT) for cerebral venous thrombosis (CVT) amidst ongoing uncertainty in the medical community.
  • A retrospective analysis of 61 CVT patients showed that EVT was performed in 20% of cases, leading to significant improvements in neurological function, as measured by the NIHSS score, from baseline to discharge.
  • The results suggest that EVT combined with anticoagulation is safe and may benefit select patients, although further research is needed to confirm its overall effectiveness.

Background: Transfemoral access is predominantly used for mechanical thrombectomy in patients with stroke with a large vessel occlusion. Following the interventional cardiology guidelines, routine transradial access has been proposed as an alternative, although its safety and efficacy remain controversial. We aim to explore the noninferiority of radial access in terms of final recanalization.

The identification of large vessel occlusion with underlying intracranial atherosclerotic disease (ICAS-LVO) before endovascular treatment (EVT) continues to be a challenge. We aimed to analyze baseline clinical-radiological features associated with ICAS-LVO that could lead to a prompt identification. We performed a retrospective cross-sectional study of consecutive patients with stroke treated with EVT from January 2020 to April 2022.

Occult atrial fibrillation (AF) is a common cause of cryptogenic stroke. This study aimed to investigate the utility of surrogate markers within the clot (clot markers), in combination with serum biomarkers, to identify AF-associated clots in patients who underwent mechanical thrombectomy. Each retrieved thrombus was analyzed to identify fibrin, red blood cells, platelets - CD61 staining (PLT) and T-CD4 lymphocyte/macrophage/monocyte (CD4) profile.

Introduction: Cerebral amyloid angiopathy (CAA) is characterized by the accumulation of amyloid-β (Aβ) in brain vessels and is a main cause of lobar intracerebral hemorrhage (ICH) in the elderly. CAA is associated with magnetic resonance imaging (MRI) markers of small vessel disease (SVD). Since Aβ is also accumulated in Alzheimer's disease (AD) in the brain parenchyma, we aimed to study if several single nucleotide polymorphisms (SNPs) previously associated with AD were also associated with CAA pathology.

Background: We aim to assess whether time of day modified the treatment effect in the RACECAT trial (Direct Transfer to an Endovascular Center Compared to Transfer to the Closest Stroke Center in Acute Stroke Patients With Suspected Large Vessel Occlusion Trial), a cluster-randomized trial that did not demonstrate the benefit of direct transportation to a thrombectomy-capable center versus nearest local stroke center for patients with a suspected large vessel stroke triaged in nonurban Catalonia between March 2017 and June 2020.

Methods: We performed a post hoc analysis of RACECAT to evaluate if the association between initial transport routing and functional outcome differed according to trial enrollment time: daytime (8:00 am-8:59 pm) and nighttime (9:00 pm-7:59 am). Primary outcome was disability at 90 days, as assessed by the shift analysis on the modified Rankin Scale score, in patients with ischemic stroke.
