Coagulation Factors and White Matter Hyperintensities in Middle-Aged Women With and Without Migraine and Ischemic Stroke.

Background: Migraine increases the risk of ischemic stroke and white matter hyperintensities (WMH), especially in women. Underlying shared mechanisms may include endothelial activation and hypercoagulability. We assessed these markers in middle-aged women with and without migraine and ischemic stroke to explore their role in WMH development.

The crisis of the third day in intracranial pressure dynamics following traumatic brain injury, fact or fiction?

Introduction: In 1960, Lazorthes and Campman introduced the concept of a which gained prominence in the field of traumatic brain injury (TBI), where it relates to neurological deterioration on the third day after injury. However, evidence regarding this phenomenon remains scarce.

Research Question: This study aimed to analyze posttraumatic intracranial pressure (ICP) patterns in a large European cohort to investigate the existence of a third-day crisis and its impact on 12-month functional outcomes.

Neuropsychiatric symptoms with focus on apathy and irritability in sporadic and hereditary cerebral amyloid angiopathy.

Background: Neuropsychiatric symptoms (NPS) may affect cognition, but their burden in cerebral amyloid angiopathy (CAA), one of the main causes of intracerebral hemorrhage (ICH) and dementia in the elderly, remains unclear. We investigated NPS, with emphasis on apathy and irritability in sporadic (sCAA) and Dutch-type hereditary (D-)CAA.

Methods: We included patients with sCAA and (pre)symptomatic D-CAA, and controls from four prospective cohort studies.

Depressive symptoms and anti-N-methyl-D-aspartate-receptor GluN1 antibody seropositivity in the PROSpective cohort with incident stroke.

Background: Anti-NMDA-receptor GluN1 antibodies (NMDAR1-abs) are present in an autoimmune encephalitis with severe neuropsychiatric symptoms. We aimed to estimate the impact of serum NMDAR1-abs on depressive symptoms years after first-ever ischemic stroke (IS).

Methods: Data were used from the PROSpective Cohort with Incident Stroke-Berlin (PROSCIS-B; NCT01363856).

Vasoregulatory Autoantibodies and Clinical Outcome After Ischemic Stroke-PROSCIS-B.

Background: Vasoregulatory autoantibodies including autoantibodies targeting G-protein-coupled receptors might play a functional role in vascular diseases. We investigated the impact of vasoregulatory autoantibodies on clinical outcome after ischemic stroke.

Methods And Results: Data were used from the PROSCIS-B (Prospective Cohort With Incident Stroke-Berlin).

Predicting 30-day mortality in intensive care unit patients with ischaemic stroke or intracerebral haemorrhage.

Background: Stroke patients admitted to an intensive care unit (ICU) follow a particular survival pattern with a high short-term mortality, but if they survive the first 30 days, a relatively favourable subsequent survival is observed.

Objectives: The development and validation of two prognostic models predicting 30-day mortality for ICU patients with ischaemic stroke and for ICU patients with intracerebral haemorrhage (ICH), analysed separately, based on parameters readily available within 24 h after ICU admission, and with comparison with the existing Acute Physiology and Chronic Health Evaluation IV (APACHE-IV) model.

Design: Observational cohort study.

Protocol of the Berlin Long-term Observation of Vascular Events (BeLOVE): a prospective cohort study with deep phenotyping and long-term follow up of cardiovascular high-risk patients.

Introduction: The Berlin Long-term Observation of Vascular Events is a prospective cohort study that aims to improve prediction and disease-overarching mechanistic understanding of cardiovascular (CV) disease progression by comprehensively investigating a high-risk patient population with different organ manifestations.

Methods And Analysis: A total of 8000 adult patients will be recruited who have either suffered an acute CV event (CVE) requiring hospitalisation or who have not experienced a recent acute CVE but are at high CV risk. An initial study examination is performed during the acute treatment phase of the index CVE or after inclusion into the chronic high risk arm.

Iatrogenic Cerebral Amyloid Angiopathy Post Neurosurgery: Frequency, Clinical Profile, Radiological Features, and Outcome.

Background: Prion-like transmission of amyloid-ß through cadaveric dura, decades after neurosurgical procedures, has been hypothesized as an iatrogenic cause of cerebral amyloid angiopathy (CAA). We investigated new and previously described patients to assess the clinical profile, radiological features, and outcome of this presumed iatrogenic CAA-subtype (iCAA).

Methods: Patients were collected from our prospective lobar hemorrhage and CAA database (n=251) with patients presenting to our hospital between 2008 and 2022.

The Post-Venous Thromboembolism Functional Status Scale: From Call to Action to Application in Research, Extension to COVID-19 Patients, and Its Use in Clinical Practice.

A broad spectrum of long-term sequelae may be present in venous thromboembolism (VTE) survivors, affecting their quality of life and functioning. To monitor recovery and improve the prognosis of patients with persistent functional limitations, the development of a new outcome measure that could better capture the consequences of VTE was an unmet need. Starting as a call to action, the Post-VTE Functional Status (PVFS) scale was developed to meet this need.

The argument for adopting a jurisprudence platform for scientific misconduct.

In this paper we will describe the arguments to adopt a jurisprudence platform for scientific misconduct, we argue that this will increase the principle of legal certainty, improve procedures, and will promote scientific integrity in other, indirect ways. With the platform that we are currently setting up in the Netherlands as a motivating example, we finally also describe the prerequisites for such a platform, its contents as well as its value in the international context.

Impact of time between thrombolysis and endovascular thrombectomy on outcomes in patients with acute ischaemic stroke.

Background: Benefits of endovascular thrombectomy (ET) after intravenous thrombolysis (IVT) for patients with acute ischaemic stroke (AIS) have been demonstrated, but analyses of the relationship between IVT-ET time delay and functional outcomes among patients receiving both treatments are lacking.

Methods: We used data from the "Berlin-Specific Acute Treatment in Ischaemic and haemorrhAgic stroke with Long-term outcome" (B-SPATIAL) registry. Between January 1st, 2016 and December 31st, 2019, we included patients who received both IVT and ET.

Low ankle-brachial index and cognitive function after stroke-the PROSpective with Incident Stroke Berlin (PROSCIS-B).

Introduction: Low ankle-brachial index (ABI) ≤0. 9 is a marker for generalized atherosclerosis and a risk factor for cognitive decline in the general population.

Objective: To evaluate the impact of ABI ≤0.

Proportion of stroke types in Madagascar: A tertiary-level hospital-based case series.

Background: Like other countries in sub-Saharan Africa, Madagascar has a high burden of stroke. The Malagasy population is unique in sharing both African and Asian ancestry. The proportion of ischemic and hemorrhagic stroke types is unknown for this population.

Publication rates in small German trials remained low five years after trial completion.

Objective: To investigate publication rates in small trials and to explore which factors are associated with publication rates in small trials, including sample size, the type and number of primary and secondary outcomes.

Study Design And Setting: We studied a subgroup of 'small' trials from a pre-existing dataset (IntoValue), containing German trials completed between 2009 and 2017. Small trials were defined as phase II-III, III and IV trials with 150 or fewer participants.

Recommendations for empowering early career researchers to improve research culture and practice.

Early career researchers (ECRs) are important stakeholders leading efforts to catalyze systemic change in research culture and practice. Here, we summarize the outputs from a virtual unconventional conference (unconference), which brought together 54 invited experts from 20 countries with extensive experience in ECR initiatives designed to improve the culture and practice of science. Together, we drafted 2 sets of recommendations for (1) ECRs directly involved in initiatives or activities to change research culture and practice; and (2) stakeholders who wish to support ECRs in these efforts.

Serum anti-NMDA-receptor antibodies and cognitive function after ischemic stroke (PROSCIS-B).

Objective: We aimed to investigate whether serum anti-N-methyl-D-aspartate-receptor GluN1 (previously NR1) antibody (NMDAR1-abs) seropositivity impacts cognitive function (CF) in the long term following ischemic stroke.

Methods: Data were used from the PROSpective Cohort with Incident Stroke-Berlin. NMDAR1-abs (IgM/IgA/IgG) were measured with cell-based assays from serum obtained within 7 days after the first-ever stroke.

Combined Oral Triglyceride and Glucose Tolerance Test After Acute Ischemic Stroke to Predict Recurrent Vascular Events: The Berlin "Cream&Sugar" Study.

Background: Elevated triglyceride and glucose levels are associated with an increased cardiovascular disease risk including ischemic stroke. It is not known whether the response to a combined oral triglyceride and glucose challenge after ischemic stroke improves identification of patients with increased risk for recurrent vascular events.

Methods: The prospective, observational Berlin "Cream&Sugar" study was conducted at 3 different university hospital sites of the Charité-Universitätsmedizin Berlin, Germany, between January 24, 2009 and July 31, 2017.
