Background: To reassess the use of antifibrinolytics (AF) in the management of aneurysmal subarachnoid hemorrhage (SAH) in the setting of present-day treatment strategies.
Method: The authors conducted a systematic review of the literature and a meta-analysis. They reviewed the PubMed database and conducted a manual review of article bibliographies.
Results: Using a pre-specified search strategy, 17 relevant studies involving a total of 2,872 patients with SAH at baseline, from which data of 1,380 patients having received AF, were included in a meta-analysis. Pooled odds ratios of the impact of AF on functional outcomes, rebleeding, and cerebral infarction were calculated. Short-term use of AF (72 h or less) associated with medical prevention of ischemic deficit seems to yield better results on functional outcome than long-term use of AF, especially if not associated with a medical prevention of ischemic deficit. The risk of cerebral infarction is not increased by the short-term use of AF and the risk of rebleeding is decreased independently of the length of AF use.
Conclusions: The use of AF should be reconsidered in the setting of modern-era treatment strategies, as the short-term use associated with medical prevention of ischemic deficit decreases the rate of rebleeding and does not increase the risk of cerebral infarction, thus potentially yielding better protection against poor functional outcome.

Ischemic stroke, caused by blocked cerebral blood flow, requires prompt intervention to prevent severe motor and cognitive impairments. Despite extensive drug development efforts, the failure rate of clinical trials remains high, highlighting the need for novel therapeutic approaches. This study investigated the therapeutic potential of a natural herbal extract mixture of Bunge (AM) and Georgi (SB), traditionally used in Eastern Asian herbal medicine (EAHM) for ischemic stroke treatment.

Background/objectives: Recent advances in stroke genetics have substantially enhanced our understanding of the complex genetic architecture underlying cerebral infarction and other stroke subtypes. As knowledge in this field expands, healthcare providers must remain informed about these latest developments. This review aims to provide a comprehensive overview of recent advances in stroke genetics, with a focus on cerebral infarction, and discuss their potential impact on patient care and future research directions.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease characterized by leukopenia and thrombocytopenia, and aspergillosis is a common complication in severe cases. Previous studies have reported cases of SFTS complicated with invasive pulmonary aspergillosis (IPA) and central nervous system aspergillosis. Here, we present the first case of an immunocompetent patient with SFTS who progressed to IPA and Aspergillus endocarditis after glucocorticoid treatment, and embolism of the vegetations from the left ventricle led to multiple infarctions in the brain, kidney, and spleen.

Background: Current randomized controlled trials are investigating the efficacy and safety of mechanical thrombectomy (MT) in patients with medium vessel occlusion (MeVO) stroke. Whether best medical management (MM) is more efficient than unsuccessful vessel recanalization during MT remains unknown.
Methods: This was a retrospective cohort study using data from 37 academic centers across North America, Asia, and Europe between September 2017 and July 2021.
