AI Article Synopsis
- The study explored the necessity of digital subtraction angiography (DSA) alongside magnetic resonance angiography (MRA) for diagnosing ischemic stroke causes in young patients.
- Out of 17 young patients assessed, both DSA and MRA yielded the same etiology in 12 cases, and in 15 cases, treatment would not have changed based on the imaging method used.
- The findings suggest that DSA might be unnecessary for about two-thirds of ischemic strokes in younger patients, indicating a need for larger studies to assess when DSA is truly needed.
Article Abstract
Purpose: We preliminarily investigated the relevance of performing digital subtraction angiography (DSA) in addition to magnetic resonance angiography (MRA) in definition of ischemic stroke etiology in young patients.
Method: DSAs and MRAs from 17 young patients with nonlacunar ischemic stroke were blindly analyzed and their impact on stroke management was evaluated.
Results: Etiologies were the same considering results of either DSA or MRA in 12/17 cases. In 15/17 patients no changes would have been made in treatment, regardless of the modality of angiography considered.
Conclusion: These preliminary results suggest that DSA may be redundant in two thirds of ischemic strokes in young patients. Further larger prospective studies are necessary to determine indications of DSA in this age group.

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.

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.
Risk and Mortality of Cardiovascular Diseases in Patients with Dupuytren's Disease: A Nationwide Population-Based Cohort Study.
Plast Reconstr Surg
December 2024
Department of Plastic and Reconstructive Surgery.
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.

Department of Neurology, The Third Xiangya Hospital, Central South University, Changsha, Hunan, China.
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.
