Filter by:The purpose of the ImpACT-24col sub-study is to explore effect of SPG stimulation on the augmentation of collateral blood flow and to relate it to the subject's cerebral blood flow status, the extent of the collateral vessel potency prior to the stimulation and the relation of the vessel occlusion site to the vasodilatory effect by using digital subtraction angiography (DSA), the gold standard imaging technique to demonstrate collateral blood flow dynamics. The results of this study will further promote the knowledge towards optimization of SPG stimulation to treat acute ischemic stroke patients.
The aim of this study is to evaluate the effect of leg elevation on the prevention of intraoperative hypotension during shoulder surgery in the Beach-chair position. patients undergoing shoulder surgery in the Beach-chair position will be randomly assigned to Group L (with leg elevation) or Group C (no intervention). The primary outcome is the incidence of intraoperative hypotension (mean blood pressure < 60mmHg or systolic blood pressure < 80% of baseline). Secondary outcomes are the incidence of intraoperative cerebral desaturation (cerebral oxygen saturation < 80% of baseline, longer than 30 seconds), total amounts of administered inotropic agents, and systolic blood pressure, heart rate, and cerebral oxygen saturation at various time points.
Personalized therapy as prophylaxis in ischemic stroke patients is not yet an option. From patients with ischemic heart disease, we know that patients with in vitro high on treatment platelet reactivity (HTPR) have an increased risk of stent thrombosis following per-cutaneous coronary intervention. Other studies have shown association of CYP2C19 genotypes with different responses to the anti platelet drug Clopidogrel. We measure HTPR in ischemic stroke patients on increasing doses of clopidogrel and investigate the CYP2C19 genotype for each patient.
Stroke is the first most common cause of death in China and one of the major causes of functional disability in the adult population.The burden of stoke is significantly increased in China in recent years. In order to investigate the prognosis of stroke, with diagnostic and treatment information of traditional Chinese medicine (TCM), and assess the effectiveness and safety of TCM for stroke in southern China, the investigators will conduct this multicenter prospective registry study in southern China. This study will recruit 10,000 consecutive eligible patients with acute stroke from more than 50 hospitals. 24 months follow-up will be carried out on-site in hospitals and by telephone to track endpoint (including all-cause mortality, composite cerebrovascular and cardiovascular events at one and two year follow up, and neurological and functional assessments).
A stroke is the second cause of deaths after heart attack, one of the most important causes of malfunction as far as adults are concerned and the second as for the frequency cause of dementia. In spite of a possibility of the therapy of stroke ( tissue plasminogen activator) and recognized most of risk factors there is expected that incidence rate on stroke connected with ageing of the society will be growing. It will cause medical and social consequences. There are many of potential causes of cardiac strokes, which are not entirely examined. More over many cryptogenic strokes are presumed to have an embolic etiology, and the frequent cause of these kind of strokes at young age is probably the mechanism of paradoxical embolism through patent foramen ovale. As far as the investigators are concerned, at present there is lack of any recommendations for these scientific hypothesis.
Stroke is one of the leading causes of death worldwide and the main cause of incapacity. Currently, the only therapies for acute ischemic stroke (AIS) patients are the administration of recombinant tissue plasminogen activator (rt-PA) and/or endovascular treatment. Unfortunately, many patients cannot benefit from these therapies due to contraindications or evolution time. Neuroprotective therapies could not only increase the benefits of available reperfusion therapies but also provide an option for patients who are not candidates for these treatments. Remote ischemic conditioning, consisting on brief episodes of transient limb ischemia, represents a new paradigm in neuroprotection. It can be categorized in pre-, per- or postconditioning, depending on the moment of application. According to studies in coronary ischemia, remote ischemic perconditioning (RIPerC) during the ischemic event is safe, cost-effective, feasible and associated with a reduction in myocardial injury. The investigators aim to conduct a multicentre study (5 university hospitals) of pre-hospital RIPerC in AIS patients (within 8 hours of stroke onset), which would include 572 stroke code activated patients (286 would undergo RIPerC and 286 would be sham). Our hypothesis is that RIPerC would be safe and would induce endogenous neuroprotective phenomena associated with good outcomes in AIS patients whether treated with revascularization therapies or not. Moreover, the development of systemic ischemic tolerance should provide metabolomic and lipidomic signatures that would present an opportunity to find specific molecular markers (biomarkers). The main objectives will be to assess: 1) RIPerC clinical benefits in AIS, 2) whether RIPerC is safe not only in AIS but also in all cases of stroke code activation, 3) whether RIPerC is associated with a reduction in cerebral infarct size and 4) metabolomic and lipidomic signatures of the RIPerC effect.
The FLAG1 study will assess the diagnostic performance of biomarkers Glutathion S-Transferase-π (GST-π) and Peroxyredoxin 1 (PRDX1) to identify cerebral infarction of less than 4,5 hours in a population of patients with neurological deficiency of less than 12 hours.
This is a randomized, sham-controlled, patient masked, outcome assessor-blinded study to assess a Pharyngeal Electrical Stimulation (PES) Catheter for treatment of oropharyngeal dysphagia following a stroke.
The study is to investigate the feasibility and safety of autologous umbilical cord blood transfusion to treat the newborn infants with presence of clinical indications of neonatal hypoxic-ischemia encephalopathy (HIE) and anemia. Umbilical cord blood (UCB) is collected following labor and is transfused intravenously within 48 hours after the birth. Newborn infant without UCB available recieves the standard care will be enrolled as control group. Following the autologous UCB transfusion in the study group or standard care in the control group, HIE subjects will be followed for 2 years for survival and neurodevelopmental outcomes and anemia subjects will be followed for 6 months to assess the survival and change of hematocrit and hemoglobin levels.
To investigate the efficacy and safety of MCI-186 (bolus followed by continuous infusion) in acute ischemic stroke patients through a double-blind, parallel-group comparison with the existing MCI-186 dosing regimen (administration twice daily for 14 days) as the control.
