Background: We aimed to investigate the prognostic role of β-synuclein in comparison to that of neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) for predicting functional outcome after acute ischemic stroke (AIS).

Methods: We measured serum concentrations of β-synuclein, NfL and GFAP 24 h after hospital admission in 213 consecutive patients with moderate-to-severe AIS. We investigated the association between serum biomarkers and radiological/clinical characteristics, 3-months mortality and functional outcome on the modified Rankin Scale (mRS).

The most recurrent familial cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) is the presence of an abnormal number of intronic GGGGCC (GC) repetitions in the C9orf72 gene, which has been proposed to drive ALS/FTD pathogenesis. Recently, it has been shown that such GC repetitions can fold into G-quadruplex (G4) secondary structures. These G4s have been selectively stabilized by small-molecule binders, furnishing proof-of-principle that targeting these non-canonical nucleic acid sequences represents a novel and effective therapeutic strategy to tackle neurodegenerative disorders.

Background: Sex may impact clinical outcomes in patients with stroke treated with dual antiplatelet therapy (DAPT). We aimed to investigate the sex differences in the short-term outcomes of DAPT within a real-world population of patients with noncardioembolic mild-to-moderate ischemic stroke or high-risk transient ischemic attack.

Methods: We performed a propensity score-matched analysis from a prospective multicentric cohort study (READAPT [Real-Life Study on Short-Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or Transient Ischemic Attack]) by including patients with noncardioembolic mild-to-moderate stroke (National Institutes of Health Stroke Scale score of 0-10) or high-risk transient ischemic attack (age, blood pressure, clinical features, duration of transient ischemic attack, presence of diabetes [ABCD] ≥4) who initiated DAPT within 48 hours of symptom onset.

: Four randomized controlled trials (RCTs) did not show a benefit of direct oral anticoagulant (DOAC) treatment compared with antiplatelet therapy for the prevention of recurrent strokes in patients with embolic stroke of undetermined source (ESUS). However, the balance between efficacy and safety in subgroups needs to be better defined. We aimed to assess the relative benefits of DOACs in key subgroups of adult patients with ESUS.

Article Synopsis
  • - Short-term dual antiplatelet treatment (DAPT) shows better effectiveness compared to single antiplatelet treatment (SAPT) for preventing secondary strokes in patients with mild to moderate strokes and high-risk TIAs, according to a study of 2016 patients.
  • - Patients treated with DAPT had a higher likelihood of regaining pre-stroke neurological function within 90 days and showed more early neurological improvement compared to those on SAPT.
  • - The study suggests that DAPT might be a safer and more effective option than SAPT in real-world settings, even for patients not fitting the criteria of major clinical trials.

  • A study aimed to compare outcomes of general anesthesia (GA) versus non-general anesthesia (non-GA) in patients aged 90 and older undergoing mechanical thrombectomy (MT) for acute ischemic stroke, a group often excluded from previous research.
  • The analysis included 139 patients, with those receiving non-GA showing significantly worse outcomes in 90-day modified Rankin Scale (mRS) scores and higher mortality rates.
  • The findings suggest that nonagenarians treated with MT without GA have poorer prognoses, highlighting the need for further research on anesthesia techniques for this age group.

Guanine quadruplexes (G4s) are nucleic acid structures present in diverse regions of the genome, such as telomeres and transcription initiators. Recently, the different biological roles of G4s have been evidenced as well as their role as biomarkers for tumors or viral infections. However, the fast and efficient detection of G4s in complex matrices remains elusive.

Article Synopsis
  • * Common causes of IS during ECMO include thromboembolic events and reduced blood flow to the brain, which can be hard to diagnose due to patients' severe conditions and sedation.
  • * Diagnosis involves immediate brain imaging, such as CT and CT angiography, while treatment typically requires mechanical thrombectomy instead of thrombolytic therapy due to ongoing anticoagulation, necessitating close collaboration between radiologists and the ECMO team.

Background: Emerging evidence indicates a frequent occurrence of atrial fibrillation (AF) detection among patients with established causes of ischemic stroke unrelated to AF. This systematic review and meta-analysis aimed to evaluate AF detection rates in stroke patients with large or small vessel disease, considering the AF detection modality and duration of cardiac rhythm monitoring.

Aims: We conducted a comprehensive search of PubMed and Scopus databases up to 2 March 2024, to identify randomized controlled trials, non-randomized prospective studies, and retrospective studies assessing the frequency of AF detection in stroke patients with large or small vessel disease.

  • The discovery of a guanine quadruplex in the TMPRSS2 mRNA could lead to innovative anticancer and antiviral treatments, as TMPRSS2 is linked to both cancer and respiratory viral infections like SARS-CoV-2.
  • TMPRSS2 facilitates virus entry into cells by aiding membrane fusion through its proteolytic activity, making it a significant target for therapeutic strategies.
  • An experimental-computational approach has resolved the first atomic-level structure of the guanine quadruplex in TMPRSS2 RNA, revealing a rigid core and flexible loop, crucial for developing targeted ligands.

Background: Atrial fibrillation (AF) can be known before the stroke (KAF) or be newly detected after stroke (AFDAS). It is unknown whether the outcome of stroke differs between KAF and AFDAS. We performed a propensity-matched analysis to investigate the outcome of patients with AFDAS and their counterparts with KAF.

  • Endovascular treatment (EVT) is advised for acute ischemic stroke caused by large-vessel occlusion (LVO) in patients with a decent early CT score (ASPECTS ≥ 6), but recent studies examine its effectiveness in patients with more severe strokes (ASPECTS 0-5).
  • A meta-analysis of six randomized controlled trials (involving 1656 patients) found that EVT significantly improves functional independence and the chances of achieving good functional outcomes after 90 days compared to best medical treatment (BMT) alone.
  • Although EVT leads to higher rates of symptomatic intracranial hemorrhage (sICH), the benefits in terms of improved function at three months outweigh the risks, especially for patients with large

Basilar artery occlusion (BAO) is a neurological emergency associated with a high risk for adverse outcomes. This review provides evidence on the therapeutic efficacy of intravenous thrombolysis (IVT) and endovascular therapy (EVT) in the treatment of BAO. Historically considered the primary intervention for acute ischemic stroke, IVT has been progressively combined with EVT, which has emerged from recent studies demonstrating clinical benefits, notably in patients presenting with severe stroke.
