Background: Recent studies have found an underutilization of hospital in-patient care for coronary artery disease in Hispanics living in border states.
Objective: To identify acute treatment disparities in acute ischemic stroke Hispanic patients and determine the effect of such disparity on patient outcomes.
Methods: We identified Hispanic and non-Hispanic acute ischemic stroke patients from the Nationwide Inpatient Sample-2011 data files. We determined the rate of utilization of thrombolytics and outcomes according to patient's demographic and clinical characteristics and whether or not they lived in a border state (defined as California, Arizona, New Mexico, and Texas).
Results: A total of 34,904 Hispanic patients were admitted with ischemic stroke; of those 21,130 were admitted in border states and 13,774 in nonborder states. There was a significantly lower rate of thrombolytic use in Hispanic patients (1013 (4.8%) and non-Hispanics (5326 (5.7%, =0.05)). After adjusting for age, gender, and other confounding risk factors, Hispanics were 30% more likely to suffer in-hospital mortality versus there non-Hispanic counterparts in border states [OR 1.3 (1.1-1.6) =0.009], which was not apparent in the non-border states [OR 1.0 (0.8-1.2) =0.9].
Conclusions: There was an underutilization of thrombolytics and higher mortality in the Hispanic population admitted in border states but not in nonborder states. Further studies are warranted to better understand the associated factors.

Safety and efficacy of tirofiban in the endovascular treatment of intracranial aneurysms: a systematic evaluation and meta-analysis.

Patients with intracranial aneurysms (IA) undergoing endovascular treatment face varying risks and benefits when tirofiban is used for thromboprophylaxis during surgery. Currently, there is a lack of high-level evidence summarizing this information. This study aims to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of tirofiban during endovascular treatment of IA.

Background: Automated machine learning (ML)-based large vessel occlusion (LVO) detection algorithms have been shown to improve in-hospital workflow metrics including door-to-groin time (DTG). The degree to which care team engagement and interaction are required for these benefits remains incompletely characterized.
Methods: This analysis was conducted as a pre-planned post-hoc analysis of a randomized prospective clinical trial.
Effect of SARS-CoV2 Infection on Endovascular Thrombectomy Outcomes - Data from the Florida Stroke Registry.

From the University of Miami Department of Neurology (H.B.F., I.R., R.Y., A.A., M.S., Y.H., A.A., C.M.G., V.J.D.B., R.M.S., T.R., H.G., J.G.R., N.A.), Miami, FL, USA; University of South Florida Department of Neurology (D.Z.R. A.J.), Tampa, FL, USA.
Background And Purpose: Endovascular thrombectomy outcomes are impacted by changes in stroke systems of care. During the pandemic, SARS-CoV2 positive status had major implications on hospital arrival and treatment models of non-COVID related hospital admissions. Using the Florida Stroke Registry, we compared the rates of in-hospital death and discharge outcomes of patients treated with endovascular thrombectomy who tested positive for SARS-CoV2 infection during their hospitalization.

Human embryonic stem cells (hESCs) and their extracellular vesicles (EVs) hold significant potential for tissue repair and regeneration. Neural stem cells (NSCs) in the adult brain often acquire senescent phenotypes after ischemic injuries, releasing neurodegenerative senescence-associated secretory phenotype factors. In this study, we investigated the senotherapeutic effects of hESC-EVs on NSCs and confirmed their neuroprotective effects in neurons via rejuvenation of NSC secretions.

Department of Neurosurgery, University of Occupational and Environmental Health, Kitakyushu, Japan.
Introduction: Our previous work demonstrated that evaluating large ischemic cores using the apparent diffusion coefficient (ADC) could predict EVT outcomes, with the most frequent ADC (peak ADC) ≥520×10 mm/s associated with better clinical results. Since the degree of ADC reduction reflects the severity of ischemic stress, this study aimed to assess the utility of an ADC color map in visualizing this stress.
Patients And Methods: This retrospective cohort study included consecutive patients with a low Alberta Stroke Program Early Computed Tomography Score (ASPECTS) using diffusion-weighted imaging (DWI) who underwent successful EVT recanalization between April 2014 and March 2023.
