Active clinical trials for "Intracranial Hemorrhages"

Intraventricular hemorrhage (IVH) is the most commonly recognized cerebral lesion on ultrasound in extremely preterm infants. Papile classification is commonly used to grade the severity of IVH. Grade III-IV IVH and other lesions noted on ultrasound including periventricular leukomalacia (pvl) porencephaly, and ventriculomegaly are well Documented to be associated with adverse neurodevelopmental outcomes. However, the true impact of lower-grade IVH on the neurodevelopment of these extreme preterm infants has not been well described. Also Neurodevelopmental outcome for neonatal non-traumatic Intra Cranial Hemorrhage (ICH) is not well established. The aim of this study is to look retrospectively at babies with neonatal IVH or ICH and follow their radiological, cognitive, motor and functional outcomes. The study will focus on postnatal files, and on images performed as part of the child's follow-up during hospitalization and after discharge.

The purpose of this prospective cohort study is to investigate whether antithrombotic therapy in the secondary prevention of ischemic stroke increases the risk of the emerging CMBs and whether the change is associated with an increased risk of intracranial hemorrhage, providing an imaging evidence for individualized antithrombotic therapy in such patients.

This study was designed to explore the influencing factors of spontaneous intraparenchymal hemorrhage's prognosis and develop predictive models for poor prognosis by establishing a cohort of spontaneous intraparenchymal hemorrhage (including both of the supratentorial intracerebral hemorrhage and cerebellar hemorrhage), and analyzing the correlation between collected variables and patients' outcomes.

The NSR-DEV study is a longitudinal cohort study of around 280 Neonatal Seizure Registry participants that aims to evaluate childhood outcomes after acute symptomatic neonatal seizures, as well as examine risk factors for developmental disabilities and whether these are modified by parent well-being.

As one of the most serious forms of acute stroke, the early mortality rate of intracerebral hemorrhage(ICH) can be as high as 30-40%. The incidence of intracerebral hemorrhage increases with the increase of age. Under the circumstance of the aggravation of aging in China, intracerebral hemorrhage brings a certain burden to families and society. The results of several studies in recent years have failed to provide new therapeutic approaches for the treatment of cerebral hemorrhage. Therefore, novel therapeutic approaches is urgently needed for ICH. Primary and secondary prevention, acute inpatient care, and poststroke rehabilitation are all critical. The objective of this cohort study is to explore factors that might influence the long-term prognosis of patients with ICH and to further identify new potential targets for intervention.

The goal of this experimental observation study is to figure out differently expressed biomarkers in lesion tissues in traumatic brain injury or hypertension intracranial hemorrhage patients. The main questions it aims to answer is: Which RNA, protein and metabolites are differently expressed in lesion tissues? What molecular mechanism is participated in TBI or ICH? Participants will be treated by emergency operation, and their lesion tissues will be collected during the operation.

Background and study aims: Computerised Tomography (CT) head scans are frequently requested by Emergency Department (ED) clinicians as one of the investigations for their patients. This often causes a delay when waiting for specialist radiologists to report the findings of the scan. The purpose of this study is to see if online training can improve the ability of ED clinicians to interpret the scans themselves, to a level sufficient to make clinical decisions based on their findings and to explore what aspects of this process they find most challenging. Participants: Emergency Department clinicians who are working in the Emergency Departments of participating sites between April to September 2022 (inclusive), who request CT Head scans as part of their routine clinical practice. What does the study involve?: 180 ED clinicians will be recruited across 6 hospital sites in the United Kingdom. All will undertake a baseline online assessment to measure their accuracy in interpreting CT head scans. One group will then undertake an online training module, with a subsequent assessment immediately afterwards, then over the following 3 months will record interpretations for 30 CT head scans. Head images encountered in participants' routine clinical practice, and their findings, will be compared with the radiology reports for each scan. Participants will then undertake further online assessments 3 and 6 months after the start of the study. Their overall results will be compared with a control group, who will undergo the same process, but undertake the online training after they have tried to interpret 30 scans in their clinical practice. Participants will continue to base their clinical decisions on radiologist reports, not their own interpretations, so patient care will not be affected by this study.

Background: In stroke patients treated with intravenous thrombolysis (IVT), presence and high number of strictly lobar cerebral microbleeds (compatible with cerebral amyloid angiopathy, CAA) seems to be associated with increased risk of hemorrhagic transformation, symptomatic hemorrhagic transformation, remote hemorrhage, and poor functional outcome. Some of these reported CAA patients with cerebral microbleeds also had chronic lobar intracerebral haemorrhage. Few data is available on IVT-treated CAA patients showing cortical superficial siderosis. There are no reports studying factors associated with brain hemorrhagic complication or functional outcome inside a group of IVT-treated CAA patients. Our aim was to evaluate brain hemorrhagic complications on 24h-CT and functional outcome after IVT in stroke patients with CAA features on pre-IVT MRI. Methods: In our stroke center, IVT decision in patients with CAA MRI features is left at the discretion of the treating physician. We retrospectively screened pre-IVT imaging of 959 consecutive IVT-treated stroke patients (between January 2015 and July 2022) without ongoing anticoagulation therapy for probable CAA MRI features defined by modified Boston criteria. After exclusion of 119 patients with lacking MRI (n=47), with MRI showing motion artefacts (n=49) or with alternative chronic brain hemorrhage cause on MRI (n=23), 15 IVT-treated patients with probable CAA on pre-IVT MRI were identified. In these 15 patients, clinical, biological and MRI characteristics were compared between patients with vs. without post-IVT hemorrhage and between patients with poor (MRS 3-6) vs. good (MRS 0-2) functional outcome at discharge.

The clinical signs presented by a patient with a mild head injury are highly variable but remain strongly predictive of brain damage. The reference examination for the diagnosis of post-traumatic intracranial hemorrhage is currently the cerebral scanner without injection of contrast medium. Magnetic resonance imaging (MRI) tends to surpass CT in equipped centers, except for suspected bone lesions. The time required to perform brain imaging depends on the patient's clinical condition, comorbidities and treatments. The responsibility of antiplatelet agents in post-traumatic intracranial hemorrhage is currently discussed, particularly with aspirin. The hypothesis is that there is no significant difference in the proportion of intracranial hemorrhage in patients on antiplatelet agents after mild head trauma, in the absence of other factors favoring the occurrence of intracranial hemorrhage.

The NSR-GENE study is a longitudinal cohort study of approximately 300 parent-child trios from the Neonatal Seizure Registry and participating site outpatient clinics that aims to evaluate whether and how genes alter the risk of post-neonatal epilepsy among children with acute provoked neonatal seizures. The researchers aim to develop prediction rules to stratify neonates into low, medium, and high risk for post-neonatal epilepsy based on clinical, electroencephalogram (EEG), magnetic resonance imaging (MRI), and genetic risk factors.
