Article Synopsis
  • The study investigates how vascular risk factors like blood pressure, diabetes, and body mass index relate to the risk and recurrence of cervical artery dissections (CeADs), a major cause of stroke in young people.
  • Using genetic analysis, it found that higher systolic and diastolic blood pressure significantly increases the risk of CeAD, while higher body mass index showed unclear effects.
  • The research suggests that β-blockers could lower the risk of CeAD, which could help shape prevention strategies and clinical trials related to this condition.

Background: Although anxiety is common in several neurological conditions, it has been poorly investigated after spontaneous intracerebral hemorrhage (ICH).

Aims: In consecutive ICH survivors, we assessed the long-term prevalence of anxiety and its clinical and radiological determinants.

Methods: Using the Hospital Anxiety and Depression Scale (HADS), we evaluated ICH survivors enrolled in the prospective, single-center Prognosis of Intracerebral Hemorrhage (PITCH) study.

Objective: This study aimed at identifying the incidence, predictors, and impact on long-term mortality and dementia of early-onset delirium in a cohort of patients with spontaneous intracerebral hemorrhage.

Methods: We prospectively recruited consecutive patients in the Prognosis of InTra-Cerebral Hemorrhage (PITCH) cohort and analyzed incidence rate of early-onset delirium (i.e.

Objective: Neuropsychiatric (NP) symptoms are prominent features of cognitive decline, but they have been understudied in patients with spontaneous intracerebral haemorrhage (ICH). In ICH survivors, we aimed at assessing NP symptoms prevalence and profiles, and their influence on long-term outcomes.

Methods: We analysed data from consecutive 6-month ICH survivors enrolled in the Prognosis of Intracerebral Haemorrhage study.

Introduction: Intracerebral haemorrhage (ICH) in young adults is rare but has devastating consequences. We investigated long-term mortality rates, causes of death and predictors of long-term mortality in young spontaneous ICH survivors.

Patients And Methods: We included consecutive patients aged 18-55 years from the Prognosis of Intracerebral Haemorrhage cohort (PITCH), a prospective observational cohort of patients admitted to Lille University Hospital (2004-2009), who survived at least 30 days after spontaneous ICH.

Article Synopsis
  • The Thrombolysis in Ischemic Stroke Patients (TRISP) collaboration was established in 2010 to study the effectiveness and safety of intravenous thrombolysis (IVT) and has now evolved to include endovascular treatment (EVT) in a new registry called EVA-TRISP.
  • The collaboration involves 20 stroke centers committed to collecting detailed data on patients for better accuracy and investigating specific research questions regarding EVT and its outcomes.
  • The initiative aims to fill crucial gaps in knowledge about EVT's safety and effectiveness in various patient groups that may not be addressed by randomized controlled trials (RCTs), thus supporting clinical decision-making for stroke physicians.

Background And Purpose: Lifelong treatment with antiplatelet drugs is recommended following a transient ischemic attack or ischemic stroke. Bleeding complications may offset the benefit of antiplatelet drugs in patients at increased risk of bleeding and low risk of recurrent ischemic events. We aimed to investigate the net benefit of antiplatelet treatment according to an individuals’ bleeding risk.

Background And Purpose: The objective of the study was to assess the effectiveness of individual direct oral anticoagulants versus vitamin K antagonists for primary prevention of stroke (ischemic and hemorrhagic) in routine clinical practice in patients with various clinical risk factors depending on their atrial fibrillation (AF) patterns.

Methods: A nested case-referent study was conducted using data from 2 national registries of patients with stroke and AF. Stroke cases with previous history of AF were matched to up to 2 randomly selected referent patients with AF and no stroke.

Cervical artery dissection (CeAD) occurring in the context of sports is a matter of concern for CeAD patients. They seek advice on the role of sports in CeAD and on the safety of resuming sports after CeAD. The scarcity of studies and guidelines addressing these issues poses a challenge.

Intravenous thrombolysis (IVT) represents the only systemic reperfusion therapy able to reverse neurological deficit in patients with acute ischemic stroke (AIS). Despite its effectiveness in patients with or without large vessel occlusion, it can be offered only to a minority of them, because of the short therapeutic window and additional contraindications derived from stringent but arbitrary inclusion and exclusion criteria used in landmark randomized controlled clinical trials. Many absolute or relative contraindications lead to disparities between the official drug label and guidelines or expert recommendations.

Introduction: To investigate the impact of a mismatch between diffusion-weighted imaging (DWI) and fluid attenuated inversion recovery (FLAIR) on functional outcome in patients with acute stroke in a prolonged time window or unknown time of symptom onset randomized to intravenous thrombolysis or placebo.

Patients And Methods: We performed a post-hoc analysis of the European Cooperative Acute Stroke Study-4 (ECASS-4) trial. ECASS-4 was an investigator driven, phase 3, multi-center, double-blind, placebo-controlled study which randomized ischemic stroke patients presenting within 4.

Background And Purpose: Accumulating evidence from randomized controlled clinical trials suggests that tenecteplase may represent an effective treatment alternative to alteplase for acute ischemic stroke. In the present systematic review and meta-analysis, we sought to compare the efficacy and safety outcomes of intravenous tenecteplase to intravenous alteplase administration for acute ischemic stroke patients with large vessel occlusions (LVOs).

Methods: We searched MEDLINE (Medical Literature Analysis and Retrieval System Online) and Scopus for published randomized controlled clinical trials providing outcomes of acute ischemic stroke with confirmed LVO receiving intravenous thrombolysis with either tenecteplase at different doses or alteplase at a standard dose of 0.

Objective: To identify in patients who survived 6 months after a spontaneous intracerebral haemorrhage (ICH) baseline characteristics and new clinical events associated with functional decline.

Methods: In a single-centre study, we prospectively included 6-month survivors with a modified Rankin Scale (mRS) score 0-3. We defined functional decline by a transition to mRS 4-5.

Background: Patients who have had a stroke with unknown time of onset have been previously excluded from thrombolysis. We aimed to establish whether intravenous alteplase is safe and effective in such patients when salvageable tissue has been identified with imaging biomarkers.

Methods: We did a systematic review and meta-analysis of individual patient data for trials published before Sept 21, 2020.

Background: Factors associated with long-term mortality after spontaneous intracerebral hemorrhage (ICH) have been poorly investigated.

Aim: Our objective was to identify variables associated with long-term mortality in a prospective cohort of 30-day ICH survivors.

Methods: We prospectively included consecutive 30-day spontaneous ICH survivors.
