Cerebral Hemorrhage

This is a multicenter, prospective, randomized, open-label, blinded-endpoint (PROBE) trial in Chinese patients with intraventricular hemorrhage (IVH), comparing early lumbar drainage added to standard care with standard care alone. The primary objective is to evaluate whether, in patients treated with external ventricular drainage (EVD) and intrathecal urokinase, the addition of early lumbar drainage improves functional outcomes at 180 days, as measured by the modified Rankin Scale (mRS), and reduces complications.

This cluster randomized controlled trial aims to evaluate the effectiveness of a novel telemedicine-enabled integrated care model led by rural doctors in reducing cardiovascular and cerebrovascular events among elderly adults (≥65 years) at high risk of stroke in rural China. A total of 39 village clinics will be randomized to either the intervention group (digital health platform-supported integrated care) or the control group (enhanced usual care). The primary outcome is a composite of cardiovascular death, stroke, and hospitalization for heart failure or acute coronary syndrome at 36 months.

After a severe brain injury some patients survive but cannot communicate, and deciding early which of them are likely to recover consciousness remains one of the hardest problems in neurocritical care. Bedside examination alone misclassifies a substantial proportion of these patients. CyDoC-MAP is a single-centre, prospective, observational cohort study conducted at Nicosia General Hospital, the sole trauma referral centre for Cyprus. It enrols patients aged 16 years or older who are intubated within 24 hours of a moderate-to-severe traumatic brain injury or a haemorrhagic stroke (intracerebral or subarachnoid haemorrhage), and who are subsequently classified as being in a vegetative state / unresponsive wakefulness syndrome (VS/UWS) or a minimally conscious state (MCS) on the Coma Recovery Scale-Revised (CRS-R). Four assessment modalities are recorded: (1) the CRS-R, performed at least twice with an interval of at least 48 hours; (2) serum neuron-specific enolase (NSE) sampled within 24 hours of intubation; (3) the bispectral index (BIS), recorded at least twice with an interval of at least 48 hours, after five minutes of standardised noxious and auditory stimulation; and (4) in the traumatic subgroup only, 1.5 T magnetic resonance imaging performed 7-28 days after injury and graded 1-4 by lesion depth by two independent raters. Level of consciousness is reassessed with the CRS-R 6 to 12 months after the index event, and the total CRS-R score (0-23) at that reassessment is the primary outcome. The primary aim is to estimate the strength of the association between the bispectral index recorded on the ward and that later CRS-R score, and to quantify what the bispectral index adds beyond the baseline clinical assessment. The number of eligible patients at a single national centre does not support the development of a prognostic model; the study is designed to produce effect-size estimates with confidence intervals that will inform a subsequent multicentre study. The study is purely observational. No intervention is administered, no study procedure alters clinical management, and transfer to rehabilitation is never delayed for research purposes.

Cerebral haemorrhage represents a minority of acute vascular syndromes (less frequent than ischemic stroke, at around 20%), but with a therapeutic impasse, having no specific treatment. Arterial contrast ("spot sign") within the hematoma has been described in CT scans as a risk factor for further enlargement and poor prognosis. An equivalent marker has also been described in gadolinium-enhanced MRI. By studying the radiological appearance of gadolinium "spot signs" on MRI, which has better parenchymal resolution, the researchers propose to retrace the phenomenology of the acute phase of cerebral hemorrhage in order to better estimate the risk of radiological aggravation by subgroup, which could serve as a target population for future therapeutic trials.

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/

MSU-ICH is a prospective, multicenter, Week-wise-randomized, open-label, blinded-endpoint (PROBE) clinical trial comparing ultra-early prehospital blood pressure lowering delivered by a Mobile Stroke Unit (MSU) with standard Emergency Medical Services (EMS) in patients with spontaneous intracerebral hemorrhage.

This is a prospective observational cohort study of adult patients admitted to the Neurosciences Intensive Care Unit (NSICU) at UT Southwestern Medical Center. The study acquires multimodal neuromonitoring data - including SedLine quantitative EEG (qEEG) from standard-of-care monitoring, Brain4Care (B4C) noninvasive intracranial dynamics monitoring, and near-infrared spectroscopy (NIRS)-derived cerebral autoregulation (CA) indices where NIRS is already in clinical use - and links these data to bedside physiologic, medication, diagnostic, and clinical outcome variables during standard care. No alteration of clinical management occurs. The study prioritizes aneurysmal subarachnoid hemorrhage (aSAH) patients to characterize the natural history of noninvasive CA parameter evolution through the delayed cerebral ischemia (DCI) window (admission through Day 14) and provides preliminary data for subsequent interventional study design.

This study (acronym COAST Trial) is a multicenter observational registry aiming to document: patients' adherence and persistence to lipid-lowering therapy prescribed for secondary prevention; the proportion of patients achieving LDL cholesterol therapeutic targets at 3 months; the incidence of cerebrovascular recurrence and mortality at 90 days, as well as the occurrence of any adverse effects from these therapies. This information will provide a snapshot of post-stroke/TIA lipid-lowering management across centers and identify areas for improvement, offering useful data to optimize secondary prevention strategies in everyday clinical practice.

This study looks at patients with brain hemorrhage to see if a special sign on brain scans, called the "Spot Sign," combined with other scan features, can predict a higher risk of death or disability. By comparing patient outcomes with existing prediction scores, the study aims to understand whether these scan markers provide extra value in identifying patients at higher risk.

The objective of the study is to assess brain tissue perfusion by contrast-enhanced ultrasound perfusion imaging (PerCEUS) in acute brain injuries. More precisely, it aims : * to evaluate the heterogeneity of brain perfusion and thus diagnose brain tissue hypoperfusion with contrast-enhanced ultrasound. * to correlate contrast-enhanced ultrasound with perfusion measurements by usual multimodal monitoring.

Study evaluating if active irrigation by IRRAflow® with infusion of tPA will reduce the time needed for clearance of intracerebral and intraventricular hemorrhage compared with passive drainage.
