Background/objective: To evaluate the impact of the COVID-19 pandemic on hospital admissions and outcomes in patients admitted with acute ischemic stroke.
Methods: Single-center retrospective analysis of patients admitted to the hospital with acute ischemic stroke, between December 1, 2019 and June 30, 2020. Outcomes were classified as none-to-minimal disability, moderate-to-severe disability, and death based on discharge disposition, and compared between two time periods: pre-COVID-19 era (December 1, 2019 to March 11, 2020) and COVID-19 era (March 12 to June 30, 2020). We also performed a comparative trend analysis for the equivalent period between 2019 and 2020.
Results: Five hundred and seventy-five patients with a mean age (years±SD) of 68±16 were admitted from December 1, 2019 to June 30, 2020, with a clinical diagnosis of acute ischemic stroke. Of these, 255 (44.3%) patients were admitted during the COVID-19 era. We observed a 22.1% and 39.5% decline in admission for acute ischemic stroke in April and May 2020, respectively. A significantly higher percentage of patients with acute ischemic stroke received intravenous thrombolysis during the COVID-19 era (p = 0.020). In patients with confirmed COVID-19, we found a higher percentage of older men with preexisting comorbidities such as hyperlipidemia, coronary artery disease, and diabetes mellitus but a lower rate of atrial fibrillation. In addition, we found a treatment delay in both intravenous thrombolysis (median 94.5 min versus 38 min) and mechanical thrombectomy (median 244 min versus 86 min) in patients with confirmed COVID-19 infection. There were no differences in patients' disposition including home, short-term, and long-term facility (p = 0.60).
Conclusions: We observed a reduction of hospital admissions in acute ischemic strokes and some delay in reperfusion therapy during the COVID-19 pandemic. Prospective studies and a larger dataset analysis are warranted.

Effect of SARS-CoV2 Infection on Endovascular Thrombectomy Outcomes - Data from the Florida Stroke Registry.
AJNR Am J Neuroradiol
January 2025
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.

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.
Introduction: This study examined the association between cardiovascular disease (CVD) history and their dental caries experience status.
Methods: Conducted from January 2021 to June 2023, this cross-sectional cohort study involved 7,138 participants who underwent oral examinations. Data on demographic background, oral health-related behaviors, and smoking status were collected using a structured questionnaire.
Development and validation of a risk stratification model for stroke recurrence after acute ischemic stroke in young adults: A nomogram-based, multicenter retrospective study.

Objective: The prevalence of ischemic stroke in young adults has increased dramatically. However, factors associated with prognosis in this cohort have not been well studied. This study primary aimed to construct and validate a nomogram for predicting stroke recurrence and to achieve risk stratification of young adults after acute ischemic stroke (AIS).

Department of Neurology, UTHealth Houston McGovern Medical School, Houston, Texas, USA
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.
