Objectives: Racial and rural-urban differences in stroke were previously reported in demographically and socioeconomically heterogeneous populations. However, it is not clear whether they exist in more homogeneous populations. Compared to the rest of the United States, the Appalachian region is highly rural and more homogeneous, with a predominantly White and socioeconomically disadvantaged population. The goal of our study was to investigate whether racial disparities in stroke mortality exist among the Appalachian population.
Design, Setting, Participants: Patterns of stroke mortality for a seven-year period (2000-2006) were investigated in the Appalachian adult population of > or = 25 years. Data on stroke deaths were obtained from the Centers for Disease Control and Prevention, National Center for Health Statistics. Multivariable Poisson regression models were used to estimate adjusted relative risks (RR), adjusting for confounding factors.
Main Outcome Measure: Stroke death rates.
Results: Stroke mortality in Appalachia was 20.5% higher than outside Appalachia (96.67 and 80.25 per 100,000 person-years, P < .001). Stroke mortality was statistically significantly higher in African Americans than in other racial groups: Caucasians (adjusted RR = 1.428, P < .001), Asians (adjusted RR = 2.821, P < .001), and Native American Indians (adjusted RR = 3.571, P < 0.001). Rural-urban stroke mortality disparities were statistically significant outside Appalachia but not within Appalachia.
Conclusions: Racial disparities in stroke mortality exist in the Appalachian region. Further studies are warranted to investigate the rationale for possible health policy interventions and socioeconomic measures.

Prourokinase vs Standard Care for Patients With Mild Ischemic Stroke: The PUMICE Randomized Clinical Trial.
JAMA Neurol
January 2025
Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.
Importance: Trials have not demonstrated superiority of alteplase or tenecteplase vs standard care in patients with mild stroke and have raised safety concerns. Prourokinase is an alternative fibrinolytic that may have a favorable safety profile, and the benefit-risk profile of prourokinase in mild stroke is unknown.
Objective: To investigate the efficacy and safety of prourokinase in mild ischemic stroke within 4.

Background Symptomatic acute occlusions of the internal carotid artery (ICA) below the circle of Willis can cause a variety of stroke symptoms, even if the major intracranial cerebral arteries remain patent; however, outcome and safety data are limited. Purpose To compare treatment effects and procedural safety of endovascular treatment (EVT) and best medical treatment (BMT) in patients with symptomatic acute occlusions of the ICA below the circle of Willis. Materials and Methods This retrospective, multicenter cohort study from 22 comprehensive stroke centers in Europe and Asia includes patients treated between January 1, 2008, and December 31, 2022.

Background: Disorders of consciousness (DoC) in non-traumatic ICU-patients are often treated with amantadine, although evidence supporting its efficacy is limited.
Methods: This retrospective study analyzed non-traumatic DoC-patients treated with amantadine between January 2016 and June 2021. Data on patient demographics, clinical characteristics, treatment specifications, and outcomes were extracted from electronic medical records.
Hypercoagulable states in young adults with ischemic stroke in a Stroke Belt state: a retrospective study.
Front Neurol
January 2025
Department of Neurology, University of Oklahoma Health Sciences Center, Oklahoma City, OK, United States.
We theorize that the southeastern United States has a higher stroke mortality rate and higher recurrent ischemic stroke rate than the rest of the United States due to (1) an increased prevalence of hypercoagulable states among young adults in the region, (2) failure to diagnose hypercoagulable states as the cause of ischemic stroke in young adults, and (3) underutilization of anticoagulation for ischemic stroke secondary prevention in young adults with hypercoagulable states. In an attempt to investigate this hypothesis, we conducted a retrospective chart review of 311 inpatients with first-ever ischemic stroke from age 18 to 55 years at an Oklahoma academic medical center from 1 July 2011 to 30 April 2017. Using Chi-squared test, we compared the stroke etiologic diagnosis of the attending neurologist at discharge-when hypercoagulable profile results were rarely available-to the diagnosis of a vascular neurologist postdischarge who had access to all available etiologic test results.

Background: Acute ischemic stroke, especially hemorrhage cerebral infarction (HCI), resulted in the leading causes of mortality and long-term disability across populations. However, fewer researches have focused on the risk factors of first admission and recurrence of HCI.
Methods: The study included 1857 patients who underwent cerebral infarction with or without hemorrhagic transformation.
