Filter by:Neonatal hypoxic-ischemic encephalopathy (HIE) is a major cause of death or long-term disability in infants born at term in the western world, affecting about 1-4 per 1.000 life births and consequently about 5-20.000 infants per year in Europe. Hypothermic treatment became the only established therapy to improve outcome after perinatal hypoxic-ischemic insults. Despite hypothermia and neonatal intensive care, 45-50% of affected children die or suffer from long-term neurodevelopmental impairment. Additional neuroprotective interventions, beside hypothermia, are warranted to further improve their outcome. Allopurinol is a xanthine oxidase inhibitor and reduces the production of oxygen radicals and brain damage in experimental, animal, and early human studies of ischemia and reperfusion. This project aims to evaluate the efficacy and safety of allopurinol administered immediately after birth to near-term infants with HIE in addition to hypothermic treatment.
In this study, the investigators aim to evaluate the indirect revascularization outcomes of a new combination therapy of multiple burrhole procedure with promotion of arteriogenesis by intravenous (IV) erythropoietin (EPO) pretreatment on Moyamoya patients with acute neurological presentation, and outline the clinical and vascular factors associated with revascularization through the burrholes.
Subsequent and non-randomised patients, adult patients qualified for major abdominal surgeries were enrolled
This study is undertaken to determine if intravenous Lipo-PGE1 therapy would improve coronary microvascular perfusion in patients with ischemic heart disease by CMRI.
This is a registry study of the natural course of unruptured intracranial aneurysms (UIA). In addition, the investigators will analyze the benefit-risk of antithrombotic or anticoagulant therapy in patients with unruptured intracranial aneurysms associated with ischemic heart disease or ischemic cerebrovascular disease. The investigators aim to use research data to create a China national database of UIA
The effectiveness of emergency management of acute ischemic stroke has improved considerably in recent years with thrombolysis and more recently thrombectomy. This improvement is accompanied by an increase in the number of stroke survivors. One of the major issues for these ever-increasing survivors is the prevention of recurrence. According to data from the 3 French registries, more than 20% of patients have at least one recurrence. Secondary prevention treatment has demonstrated his efficacy to prevent stroke recurrence. This evolution justifies identifying factors associated with adherence to secondary prevention treatment, measured at 1 year post-stroke / transient ischemic attack (TIA), in patients included in the STROKE 69 cohort.
Ischaemic stroke causes significant morbidity and mortality and is a leading cause of disability within an ageing United Kingdom (UK) population. Proximal anterior circulation occlusion is associated with a particularly poor prognosis, but its management has undergone a paradigm shift following clinical introduction of endovascular recanalization, establishing rapid reperfusion of the ischaemic penumbra. Remote ischaemic conditioning (RIC) is highly effective at attenuating cerebral infarction in basic research studies and has the potential to further improve patient outcome if used as an adjunct to invasive revascularisation strategies. We aim to trial remote ischaemic conditioning at the time of revascularisation, and then daily for the duration of the seven-day in-patient stay, compared to a sham conditioning procedure. This pilot, single-centre study will determine efficacy/ tolerability of RIC to reduce cerebral infarction (primary endpoint: determined by brain magnetic resonance imaging [MRI]) and improve functional status (secondary end-points: National Institutes of Health Stroke Severity (NIHSS); European Quality of Life questionnaire EurQoL), with the data providing the necessary parameters for power calculations and leveraging charitable funding for a subsequent multi-centre study.
The aim of the study is to determine if single-bolus recombinant nonimmunogenic staphylokinase is effective and save thrombolytic agent in patients with ischemic stroke in comparison to alteplase.
Ischemic stroke is the first cause of acquired disability of the adult, the second cause of dementia and the third cause of death in the industrialized countries, what constitutes à major public health issue. Stroke is characterized by a cerebral parenchymal lesion due to an ischemic mechanism (85% of the cases) or hemorrhagic mechanism (15%). For a long time, the only approved treatment was the intravenous thrombolysis (rt-PA). Recently, thrombectomy has proven its superiority in this pathology. Cohorts of patients with stroke are rare but can be very valuable by their clinical, laboratory and imaging well documented. They are the source of new hypotheses for research or interventions as well as the quality of care assessment tool. The main objective of this project is to identify new markers: biological and imaging, treatment response and prognosis after ischemic stroke. Secondary objectives of the HIBISCUS-STROKE cohort are to establish a clinical database, completed by biological samples and by imaging data that can be used in the following areas: - Descriptive epidemiology of ischemic stroke and cerebral reperfusion, - Pharmacoepidemiology and treatments observatory: safety, efficacy, indication of treatment in real life, costs - Assessment of the long-term effect of the treatment on the occurrence of disability, stroke recurrence and death, - Quality of life and personal, familial, professional and social consequences of stroke, - Research of new diagnostic and prognostic biomarkers, - Research projects.
When to start anticoagulation in patients with an acute ischaemic stroke and atrial fibrillation (AF) is a relevant unanswered question in clinical practice. Direct oral anticoagulants (DOACs) are highly effective for secondary stroke prevention in these patients, but DOACs were never initiated <7 days after stroke onset in recent trials. The ELAN trial will determine the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The main objective is to estimate the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The secondary objectives are to assess all vascular events and all-cause mortality after early initiation of DOACs in patients with acute ischaemic stroke related to AF compared to late initiation.
