Objectives: Aspirin has traditionally been used as an analgesic and anti-inflammatory drug; however, low-dose aspirin is known to increase the risk of gastrointestinal and intracranial hemorrhage. In this study, the risk of intracranial hemorrhage in patients taking low-dose aspirin was assessed.
Materials And Methods: We used the Standard Sample Cohort DB dataset from the National Health Insurance Sharing Service of Korea. This dataset includes details of medical care and prescriptions for patients who used hospital services during a 14-year period throughout Korea. Of approximately 1 million total patients, data from 746,703 adults over the age of 30 years were included for analysis. An Χ test was performed to assess the effect of low-dose aspirin on intracranial hemorrhage. In addition, the relationship between use of low-dose aspirin and intracranial hemorrhage was analyzed using multiple logistic regression with consideration of all confounding variables.
Results: The results revealed no significant positive correlations between the use of low-dose aspirin and intracranial hemorrhage requiring hospitalization.
Conclusions: Big data analysis of 746,703 patients in Korea over a period of 14 years showed that serious intracranial hemorrhage requiring hospitalization was unrelated to low-dose aspirin use. Moreover, low-dose aspirin use reduced the risk of intracranial hemorrhage in Korean populations.

Endovascular Thrombectomy for Extracranial Internal Carotid Artery Occlusions With Large Ischemic Strokes: Insights From the SELECT2 Trial.
Neurology

Department of Neurology, Department of Stroke, University Hospital Cleveland Medical Center, Case Western Reserve University, Cleveland, OH.
Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).
Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.

Background: Risk factors and mechanisms of cognitive impairment (CI) after aneurysmal subarachnoid hemorrhage (aSAH) are unclear. This study used a neuropsychological battery, MRI, ERP and CSF and plasma biomarkers to predict long-term cognitive impairment after aSAH.
Materials And Methods: 214 patients hospitalized with aSAH (n = 125) or unruptured intracranial aneurysms (UIA) (n = 89) were included in this prospective cohort study.
Extracellular Vesicles From Bone Marrow-Derived Macrophages Enriched in ARG1 Enhance Microglial Phagocytosis and Haematoma Clearance Following Intracerebral Haemorrhage.

Microglial phagocytosis of haematomas is crucial for neural functional recovery following intracerebral haemorrhage (ICH), a process regulated by various factors from within and outside the central nervous system (CNS). Extracellular vesicles (EVs), significant mediators of intercellular communication, have been demonstrated to play a pivotal role in the pathogenesis and progression of CNS diseases. However, the regulatory role of endogenous EVs on the phagocytic capacity of microglia post-ICH remains elusive.

Andexanet Alfa in Acute Intracranial Hemorrhage in Patients Receiving an Oral Factor Xa Inhibitor (ANNEXA-I), the first ever randomized controlled trial of a reversal agent for direct oral anticoagulants, was published in 2024. The trial, which randomized patients with intracranial hemorrhage to andexanet alfa or usual care, was mandated by the United States Food and Drug Administration as part of its conditional approval in 2018. This approval was originally based on the single-arm trial, The Andexanet Alfa, a Novel Antidote to the Anticoagulation Effects of Factor Xa Inhibitors (ANNEXA-4).

Background: Up to 50% of patients undergoing mitral transcatheter edge-to-edge repair (MTEER) have an indication for left atrial appendage occlusion (LAAO). However, prospective evaluation of this strategy is lacking.
Objectives: The aim of the study was to prospectively evaluate the outcomes of combined LAAO and MTEER.
