Background And Objectives: Acute stroke is associated with a spectrum of functional deficits. The objective of this analysis was to explore whether the importance of individual risk factors differ by stroke severity, which may be of relevance to public health strategies to reduce disability.
Methods: INTERSTROKE is an international case-control study of risk factors of first acute stroke (recruitment 2007-August 2015) in 32 countries.
Background And Purpose: Cold beverage intake (carbonated drinks, fruit juice/drinks, and water) may be important population-level exposures relevant to stroke risk and prevention. We sought to explore the association between intake of these beverages and stroke.
Methods: INTERSTROKE is an international matched case-control study of first stroke.
Background & Aims: Wilson disease (WD) is caused by accumulation of copper primarily in the liver and brain. During maintenance therapy of WD with D-penicillamine, current guidelines recommend on-treatment ranges of urinary copper excretion (UCE) of 200-500 μg/24 h and serum non-ceruloplasmin-bound copper (NCC) of 50-150 μg/L. We compared NCC (measured by two novel assays) and UCE from patients with clinically stable WD on D-penicillamine therapy with these recommendations.

Objectives: We investigated changes in circulating LPS concentrations in acute ischemic stroke (AIS) and their consequences, including prognosis.
Methods: We studied 98 AIS patients, aged 74 ± 12 years, including 74 (75.
Background: Stroke is a leading global cause of death and disability. Daily tea/coffee intake is consumed by > 50% of populations and may represent an important population-level exposure. Therefore, it is first essential that we better understand the associations between the tea/coffee intake and stroke.

Unlike coronary disease, which is typically caused by atherosclerosis, ischaemic stroke is caused by diverse mechanisms including atherosclerosis and small vessel disease or is frequently due to an unknown cause. We aimed to investigate the hypothesis that long-term colchicine would reduce recurrent events after ischaemic stroke.

The Tranexamic acid (TXA) for hyperacute primary IntraCerebral Hemorrhage (TICH-2) trial demonstrated that tranexamic acid (TXA) reduces the risk of hematoma expansion. We hypothesized that TXA would reduce the frequency of surgery (primary outcome) and improve functional outcome at 90 days in surgically treated patients in the TICH-2 data set.

Aims: We examined differences in the prevalence of AF and described variations in the magnitude of the association between AF and ischemic stroke by country income level.
Methods: In the INTERSTROKE case-control study, participants with acute first ischemic stroke were recruited across 32 countries.
Background: People with factor XI deficiency have lower rates of ischaemic stroke than the general population and infrequent spontaneous bleeding, suggesting that factor XI has a more important role in thrombosis than in haemostasis. Milvexian, an oral small-molecule inhibitor of activated factor XI, added to standard antiplatelet therapy, might reduce the risk of non-cardioembolic ischaemic stroke without increasing the risk of bleeding. We aimed to estimate the dose-response of milvexian for recurrent ischaemic cerebral events and major bleeding in patients with recent ischaemic stroke or transient ischaemic attack (TIA).

Our aim was to assess the degree of improvement in highly stroke-oriented centres that report cases to the RES-Q each year.
Material And Methods: This retrospective analysis included Polish stroke units that from January 2017 to December 2020 contributed to the RES-Q at least 25 patients annually.
Introduction: Wilson's disease (WD) is a potentially treatable, inherited disorder resulting from impaired copper metabolism. Pathological copper accumulation causes a range of symptoms, most commonly hepatic and a wide spectrum of neurological symptoms including tremor, dystonia, chorea, parkinsonism, dysphagia, dysarthria, gait and posture disturbances. To reduce copper overload, anti-copper drugs are used that improve liver function and neurological symptoms in up to 85% of patients.

We investigated determinants of plasma protein carbonylation (PC) in AIS, its impact on the prothrombotic state, and prognostic value during follow-up.
Methods: We included 98 consecutive AIS patients aged 74±12 years (male:female ratio, 50:48 [51%:49%]) at the Neurology Center in Warsaw, Poland, between January and December 2014.
Objectives: Our aim was to investigate usefulness of the neutrophil-to-lymphocyte ratio (NLR) for predicting poor response to intravenous rtPA in white Caucasian ischemic stroke patients treated within 4.5 hours from the onset.
Materials And Methods: This retrospective analysis included all consecutive acute ischemic stroke patients (N = 344) treated with rtPA in a tertiary stroke center from 2011 to 2017.
Wilson's disease (WD) is a genetic disorder with copper accumulation in various tissues leading to related clinical symptoms (mainly hepatic and neuropsychiatric) which can be in 85% of patients successfully treated with anti-copper agents. However, during WD treatment neurological deterioration may occur in several patients. D-penicillamine (DPA) is one of the most frequently used drugs in WD treatment.

Introduction: Our study assessed changes in concentrations of serum markers for brain damage and blood-brain barrier (BBB) dysfunction in untreated and treated Wilson's disease (WD) patients, and examined correlations between these changes and neurological impairment.
Objective: These results hold the potential to determine BBB impairment and neurological advancement in WD to develop the most effective treatment for patients with severe neurological deterioration.
Material And Methods: The study groups included 171 patients with WD (77 with hepatic and 94 with neurological manifestations), treated either for up to 5 or 15 years, and 88 healthy controls.
Background: Treatment of Wilson's disease (WD), an inherited disease characterized by copper overload, is lifelong and there is the possibility that copper deficiency (CD) may occur. We systematically reviewed the literature to describe treatment patterns, symptoms and outcomes associated with CD.
Methods: Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, the PubMed database was searched up to 6 April 2023.
