Filter by:In this three-year proposal, we will explore the MRI-visible EPVS in CAA and investigate its pathophysiology using animal models. Our specific aims include: (1) Establish the relationship of MRI-visible enlarged perivascular space and CAA, (2) Determine whether vascular amyloid clearance in CAA is associated with lymphatic drainage system, (3) Establish longitudinal data for MRI-visible enlarged perivascular space and cerebral amyloid angiopathy progression.
This is an observational study in neurocritical care units at University of California San Francisco Medical Center (UCSFMC), Zuckerberg San Francisco General Hospital (ZSFGH), and Duke University Medical Center. In this study, the investigators will primarily use the monitor mode of the Transcranial Doppler (TCD, non-invasive FDA approved device) to record cerebral blood flow velocity (CBFV) signals from the Middle Cerebral Artery and Internal Carotid Artery. TCD data and intracranial pressure (ICP) data will be collected in the following four scenarios. Each recording is up to 60 minutes in length. Multimodality high-resolution physiological signals will be collected from brain injured patients: traumatic brain injury, subarachnoid and intracerebral hemorrhage, liver failure, and ischemic stroke. This is not a hypothesis-driven study but rather a signal database development project with a goal to collect multimodality brain monitoring data to support development and validation of algorithms that will be useful for future brain monitoring devices. In particular, the collected data will be used to support: Development and validation of noninvasive intracranial pressure (nICP) algorithms. Development and validation of continuous monitoring of neurovascular coupling state for brain injury patients Development and validation of noninvasive approaches of detecting elevated ICP state. Development and validation of approaches to determine most likely causes of ICP elevation. Development and validation of approaches to detect acute cerebral hemodynamic response to various neurovascular procedures.
We are attempting to improve the cerebral monitoring of extremely low gestational age (ELGA) infants, such that in the future, real-time monitoring will be possible, to aid clinicians in their management of these infants. We wish to establish a new NIRS device, diffuse correlation spectroscopy (DCS), as a safe, noninvasive and informative bedside tool for assessing and monitoring brain health in ELGA infants during the first few days of life. It is hoped that this method will provide detailed information on changes in oxygen consumption and metabolism, and cerebral perfusion. This technique will have wide applicability, but for this research study we wish to focus on the effect of blood flow instabilities, intermittent hypotension and hypoxic episodes, pressure passive CBF periods, and hypoperfusion on the preterm brain during the first days of life, and their relationship with incidence of intraventricular hemorrhage (IVH). We aim to recruit 100 premature infants to obtain data to: 1. Test the feasibility of NIRS-DCS to monitor cerebral activity, perfusion and oxygen consumption in extremely premature infants during the first week of life. 2. To assess if these baseline values are impacted by intermittent hypoxic episodes. 3. To assess if cerebral blood flow disturbances correlate with incidence of intraventricular hemorrhage. 4. Correlate the NIRS-DCS findings with clinical outcome at hospital discharge.
This is a prospective, open, multicentre trial that will enrol patients with clinical signs of stroke in the acute phase admitted for CT scan. The study assesses the diagnostic capability and safety of Strokefinder MD100.
A recent prospective observational clinical study conducted in an intensive care unit of a third level US university hospital showed that 94% of patients with ES and 50% of those with EC had an ARC for a duration of at least one day during the hospital stay. Although there is currently a great deal of evidence describing ARC in various subgroups of critically ill patients, on the other hand there is little documentation regarding the effect that ARC can have on exposure to renally eliminated drugs. Therefore, the aim of this study is to prospectively evaluate the proportion of plasma under-exposure to hydrophilic antimicrobials in patients with ES or EC and with ARC, in order to verify whether the recommended dosage regimens for these drugs are adequate for reaching the pharmacodynamic targets of therapeutic efficacy.
The aim of the observational multicenter trial encompasses the comparison of estimation of the long-term prognosis (functional and cognitive outcomes, quality of life) after intracerebral and subarachnoid hemorrhages assessed by clinical scores, treating physicians and nurses. The scores and the assessment of the treating physicians and nurses are recorded on admission, at 7 and 14 days after symptom onset.
The investigators will perform follow-up on 500 cases of deep and lobar intracerebral hemorrhage to perform advanced neuroimaging before 45 days post stroke, and evaluations of motor and cognitive function at baseline, 3 months and 6 months to determine predictors of recovery, progressive cognitive or functional impairment.
The SATURN trial aims to determine whether continuation vs. discontinuation of statin drugs after spontaneous lobar intracerebral hemorrhage (ICH) is the best strategy; and whether the decision to continue/discontinue statins should be influenced by an individual's Apolipoprotein-E (APOE) genotype. An MRI ancillary study (SATURN MRI), in a subset of SATURN participants , will evaluate the effects of continuation vs. discontinuation of statin drugs on hemorrhagic and ischemic MRI markers of cerebral small vessel disease, and whether the presence/burden of hemorrhagic markers (i.e. cerebral microbleeds and/or cortical superficial siderosis) on baseline MRI influences the risk of ICH recurrence on/off statin therapy.
Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF). Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.
PROHIBIT-ICH will randomise participants to compare a strategy of intensive BP treatment (target <120/80 mm Hg) guided by telemetric home monitoring, versus standard primary care (current RCP guideline is 130/80 mm Hg), in 112 adult survivors of hypertension-related ICH. The investigators will establish the feasibility and safety of the intervention, the efficacy of BP reduction, and explore whether it reduces the progression of SVD-related injury on brain MRI.
