Ischemic stroke often leaves survivors with permanent disabilities and therapies aimed at limiting detrimental inflammation and improving functional outcome are still needed. Tumor necrosis factor (TNF) levels increase rapidly after ischemic stroke, and while signaling through TNF receptor 1 (TNFR1) is primarily detrimental, TNFR2 signaling mainly has protective functions. We therefore investigated how systemic stimulation of TNFR2 with the TNFR2 agonist NewSTAR2 affects ischemic stroke in mice. We found that NewSTAR2 treatment induced changes in peripheral immune cell numbers and transiently affected microglial numbers and neuroinflammation. However, this was not sufficient to improve long-term functional outcome after stroke in mice.

Untangling areas of improvement in secondary prevention of ischemic stroke in patients with atrial fibrillation.

Health Services Research and Pharmacoepidemiology Unit, Foundation for the Promotion of Health and Biomedical Research of Valencia Region (FISABIO), Avenida Cataluña, 21, 46020, Valencia, Spain.

Improvement of post-stroke outcomes relies on patient adherence and appropriate therapy maintenance by physicians. However, comprehensive evaluation of these factors is often overlooked. This study assesses secondary stroke prevention by differentiating patient adherence to antithrombotic treatments (ATT) from physician-initiated interruptions or switches.

Fast and sensitive multivalent spatial pattern-recognition for circular RNA detection.

Nat Commun

December 2024

Department of Pharmacology, Jiangsu Provincial Key Laboratory of Critical Care Medicine, School of Medicine, Southeast University, Nanjing, China.

While circular RNAs (circRNAs) exhibit lower abundance compared to corresponding linear RNAs, they demonstrate potent biological functions. Nevertheless, challenges arise from the low concentration and distinctive structural features of circRNAs, rendering existing methods operationally intricate and less sensitive. Here, we engineer an intelligent tetrahedral DNA framework (TDF) possessing precise spatial pattern-recognition properties with exceptional sensing speed and sensitivity for circRNAs.

Objective: Here, we aim to investigate whether D-dimer (DD)/fibrinogen (FIB) ratio or combination of DD and FIB contribute to the prognosis of stroke and stroke subtypes.

Methods: 1413 patients with acute ischemic stroke (AIS) were recruited. We measured DD and FIB levels on admission and followed up with patients at discharge and 90-day following discharge.

Background: Dupuytren's disease (DD) is a type of fibroproliferative disease that involves the palmar aspect of the hand. Although many benign fibroproliferative diseases have been shown to increase the risk of cardiovascular disease, the relationship between DD and myocardial infarction (MI) or stroke has not been fully elucidated.

Methods: A total of 35,909 patients with DD and a control cohort with 1,077,270 age- and sex-matched participants from the Korean National Health Insurance database were included.

Background And Objective: Neutrophil extracellular traps (NETs) with inflammatory risk are important contributors to cardiovascular disease, but no definitive information is available in large artery atherosclerotic (LAA) stroke. This study aims to investigate the association between NETs with related inflammatory biomarkers and prognosis of LAA stroke in the Chinese population.

Methods: A prospective study involving 145 LAA stroke cases and 121 healthy controls was conducted.
