Filter by:The purpose of this study is to determine whether acetaminophen is effective in prevention or reducing the severity of IVH in premature infants.
This study aims to investigate the efficacy of simulation in neurosurgical training.
This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/
An investigator initiated and conducted, multicentre, international, double-blinded, placebo-controlled, parallel-group, randomised controlled trial to determine the effect of more intensive blood pressure control provided by a fixed low-dose combination blood pressure lowering pill ("Triple Pill") strategy on top of standard of care, on time to first occurrence of recurrent stroke in patients with a history of stroke due to intracerebral haemorrhage.
The purpose of this study is to determine if computed tomography angiography can predict which individuals with intracerebral hemorrhage will experience significant growth in the size of the hemorrhage. For individuals who are at high risk for hemorrhage growth, the study will compare the drug Tranexamic acid to placebo to determine the effect and safety of on intracerebral hemorrhage growth
The most frequent complications in premature infants are neurological complications: intracranial hemorrhages and white matter lesions. In Epipage 2 study the incidence of severe intraventricular hemorrhages remains stable. Severe hemorrhages are associated with neurological sequelae. A recent study in humans and in animals shows the role of the complex formed by plasminogen activator (t-PA) and its inhibitor (PAI-1) in the induction of vascular fragility via stromelysin (MMP-3). FIBRINAT study in Rouen University Hospital showed a rate of complex t-PA-PAI1 probably very high in preterm infants. An other factor maturation PDGF-C induced by t-PA is associated with the vascular embrittlement. Among the few genetic factors associated with cerebral palsy include 2 SNP of PAI-1 gene and one SNP in the gene of endothelial NO synthase. The hypothesis is that a high rate of the complex t-PA-PAI-1 in cord blood could be a high risk of intracranial hemorrhage in preterm infants and provide predictive of their occurrence. The rates of MMP-3, PDGF-C and PAI-1 free in cord blood, and the polymorphism of PAI-1 gene and eNOS could separately or associated with the main criterion to identify predictive of hemorrhages. The main objective is to search a rate difference of the complex t-PA-PAI-1 in cord blood of preterm infants (before 30 weeks of gestation) that would predict intracranial hemorrhage coming in the first days of life. The secondary objectives are - Evaluate potential marker risk of high levels of MMP-3, PAI-1 free, and PDGF-CC - Search in both groups the presence of alleles -675G4 / G5 and 11053 (G / T) of the PAI-1 gene and -922 (A / G) of the eNOS gene. 120 preterm infants will be included before 30 weeks of gestation with precise inclusion and exclusion criteria during a period of 3 years. Patients will be divided into two groups according to whether they will or not showed intracranial hemorrhage (detected by ultrasound J5-J7). The complex rate tPA-PAI-1, PAI-1 free, MMP-3 and PDGF-C will be measured. The comparison between the two groups will be carried out using statistical tests. Comparison of the presence of the alleles -675 4G and 11053T the PAI-1 gene or -922G eNOS gene between the two groups will be performed. The demonstration of this hypothesis would permit to identify children from birth in whom the immediate implementation of preventive treatment of bleeding is desirable.
The main purpose of this study is to determine whether deferoxamine and xingnaojing injection is effective and safe as a treatment for intracerebral hemorrhage.
The vast majority of intracerebral hemorrhage (ICH) patients present with elevated blood pressure(BP). Management of BP is controversial with two competing rationales. There is some evidence that hyperacute treatment may improve outcomes by reducing the rate of hematoma expansion. Physicians have been reluctant to reduce BP early after ICH onset, fearing reduced cerebral blood flow (CBF) will increase ischemia and increase the risk of further damage. Other confounding mediators to further ischemic injury following ICH include increased platelet activity, withdrawal of antithrombotic therapy, endothelial dysfunction, inflammation and hypercoagulability. This study is phase II of the ICH-ADAPT study. The investigators hypothesize that aggressive antihypertensive therapy will alter the natural history of heamatoma growth, improving outcomes after Intracranial Hemorrhage (ICH). The previous phase I ICH-ADAPT study has established the safety of early BP treatment. The investigators have designed a phase II study in which ICH patients are randomized to aggressive versus conservative BP treatment using a deferred consent procedure. An adaptive randomization will be used to treat BP to < 140 mmHg SBP or < 180 mmHg SBP. Treatment must be implemented as soon as possible after radiological confirmation of diagnosis. Antihypertensive therapy must begin within 6 hours of symptom onset. The patient will be re-imaged 24 hours later. The patient will have continuous non-invasive BP and heart rate(HR) monitoring for a minimum of 24 hours. Antihypertensive drug use and dosage will be recorded with BP and HR. Patients will be monitored regularly until study completion. MRI's will be done at 48 hours, day 7 and day 30. This imaging will help to detect ischemic changes that may occur. Blood will be collected at the same time as the MRI. Blood analysis will be done to possibly identify biomarkers that may be putative mediators of ischemic injury in ICH patients.
Early cord clamping after delivery has been common practice for many decades as part of the active management of the third stage of labour. However in recent years, several studies have shown that delayed cord clamping may offer important benefits to the newborn. The data gathered indicate that delayed cord clamping may be particularly useful in premature babies, between 26 and 32 weeks of gestational age, reducing the need for blood transfusion and the incidence of intraventricular haemorrhage. However it is argued that the described potential benefits of delayed cord clamping could be negated by the increased risk of polycythaemia and jaundice in the newborn, as well as by potential interference with the postpartum haemorrhage management, initial care and reanimation of the premature newborn, and the possibility of cord blood donation. These factors, together with as the lack of homogeneity among existing studies regarding the delayed cord clamping technique create the need, in our opinion, for further research, to establish the proper place of this measure. Our hypothesis is that delayed cord clamping in the premature newborn significatively reduces the need for blood transfusions and intraventricular haemorrhage, compared with usual early cord clamping. Secondary outcomes: - To define the impact of delayed cord clamping on neonatal assessment parameters after delivery: APGAR score, cord pH, need for mechanical ventilation or reanimation. - Neonatal mortality and morbidity - Effect of the procedure on the incidence and severity of maternal postpartum haemorrhage - To study the correlation between Iron metabolism and reticulocitary haemoglobin levels in cord and infant blood.
Early hematoma growth (HG) after spontaneous intra-cerebral/intra-parenchymal hemorrhage (IPH) is common and associated with neurological deterioration and poor clinical outcome. Temperature modulation to hypothermia (Temperature, 32-34°C) has been associated with reduction or improvement of physiopathologic processes associated with inflammatory activation and degradation of blood-brain barrier after all types of brain injury. In this sense, we believe that the initiation of an ultra-early protocol of active temperature modulation or Targeted Temperature Management (TTM) to mild induced hypothermia (MIH, 32-34°C) may be associated with good safety and tolerability profile, less HG and cerebral edema after IPH by modulation of systemic and local inflammatory responses, so we hypothesize that TTM to MIH will be a safe/tolerable and effective therapy to limit HG and cerebral edema after IPH.
