Safety and efficacy of tirofiban in preventing neurological deterioration in acute ischemic stroke (TREND): Protocol for an investigator-initiated, multicenter, prospective, randomized, open-label, masked endpoint trial.

Introduction: Antithrombotic therapy prevents adverse ischemic events following acute ischemic stroke (AIS). Intravenous tirofiban provides desirable antiplatelet effects, especially in patients who are vulnerable to neurological deterioration (ND).

Aim: The aim of the study was to test the hypothesis that intravenous administration of tirofiban, initiated within 24 h of ictus and continued for consecutive 72 h, would be more effective than aspirin in reducing the risk of ND within 72 h of enrollment among patients with potentially atherothrombotic ischemic stroke.

A Comprehensive Prediction Model for Futile Recanalization in AIS Patients Post-Endovascular Therapy: Integrating Clinical, Imaging, and No-Reflow Biomarkers.

Our study aimed to construct a predictive model for identifying instances of futile recanalization in patients with anterior circulation occlusion acute ischemic stroke (AIS) who achieved complete reperfusion following endovascular therapy. We included 173 AIS patients who attained complete reperfusion, as indicated by a Modified Thrombolysis in Cerebral Infarction (mTICI) scale score of 3. Our approach involved a thorough analysis of clinical factors, imaging biomarkers, and potential no-reflow biomarkers through both univariate and multivariate analyses to identify predictors of futile recanalization.

Elevating nucleic acid delivery via a stable anionic peptide-dextran ternary system.

Nucleic acid-based therapies hold promise for treating previously intractable diseases but require effective delivery vectors to protect the therapeutic agents and ensure efficient transfection. Cationic polymeric vectors are particularly notable for their adaptability, high transfection efficiency, and low cost, but their positive charge often attracts blood proteins, causing aggregation and reduced transfection efficiency. Addressing this, we designed an anionic peptide-grafted dextran (Dex-LipE5H) to serve as a cross-linkable coating to bolster the stability of cationic polymer/nucleic acid complexes.

Predicting ischemic stroke risk from atrial fibrillation based on multi-spectral fundus images using deep learning.

Background: Ischemic stroke (IS) is one of the most common serious secondary diseases of atrial fibrillation (AF) within 1 year after its occurrence, both of which have manifestations of ischemia and hypoxia of the small vessels in the early phase of the condition. The fundus is a collection of capillaries, while the retina responds differently to light of different wavelengths. Predicting the risk of IS occurring secondary to AF, based on subtle differences in fundus images of different wavelengths, is yet to be explored.
