Detection of Cerebral Ischemia With a Noninvasive Neurometabolic Optical Monitor
Traumatic Brain InjuryIschemic Stroke3 moreThe goals of the project are to evaluate a noninvasive monitor of brain metabolism and blood flow in critically ill humans. If validated, such a reliable noninvasive brain blood flow and metabolism monitor, by allowing physiologic and pharmacologic decisions based on real-time brain physiology, potentially will become an important tool for clinicians in their efforts to prevent additional brain tissue death in patients admitted with stroke, brain hemorrhage and traumatic brain injury.
Assessment of Patient Reported Health Status Questions Via Four Different Methods of Administration,...
StrokeCerebral Infarction5 moreA Patient Reported Outcome Measure (PROM) is a questionnaire that asks patients for their views on their own health or the impact of healthcare they have received on their health and quality of life (RCN, 2011). The benefit of PROMS is that they gather information from the patient's perspective, which offers great potential to improve the quality and outcomes of health services (Department of Health 2011). There is a PROM (the PROMIS-10 Global Health) and a number of extra questions that are recommended for use in people who have had a stroke by the International Consortium for Health Outcomes Measurement, but the best way of delivering these questions for stroke survivors is unknown. At present, the NHS in England, Scotland and Wales are required to offer every stroke survivors a 6 month post stroke follow-up appointment. Currently, the information collected at the 6 month review is not from the patient's perspective and the best method of collecting this information has not been established. The Sentinel Stroke National Audit Programme (SSNAP) which is led by the Royal College of Physicians in London promote the 6 month follow-up assessment. SSNAP recognise that currently 4 different methods of 6 month follow-up appointment occur. The current methods in use are face-to-face assessment, telephone interview, online questionnaire or postal questionnaire. The aim of this research is to understand if there is a difference between these 4 methods of delivering these questions in people who have had a stroke. As part of the 6 month review this research study will assess the response rate for 15 Patient Reported Health Status questions across the 4 recognised methods of delivery; Face-to-Face Telephone Online Post To conduct this research study a sample of 808 stroke survivors will be asked to take part in the research. From these 808 people, 202 participants will be randomly assigned to each method of administration (Face-to-Face Interview, Telephone Interview, Postal Questionnaire and Online Questionnaire). The questionnaires received by the research team will not record any personally identifiable information. The data will then be utilised by the researchers for statistical analysis in order to identify, which method of the 4 methods of administration, under investigation, is the most acceptable for stroke survivors. The conclusions of this research will inform the roll-out of the most appropriate method of delivering the 6 month stroke follow-up review for stroke survivors.
Clinical Outcomes Following Parafascicular Surgical Evacuation of Intracerebral Hemorrhage: A Pilot...
Intracerebral HemorrhageThis study is determining the clinical outcomes, based on neurological testing, for the parafascicular minimally invasive clot evacuation technique. We will collect data from the time of surgery up until 90 days post procedure. We will also be looking at financial data as well. H(0): there is no economic benefit to the system with early surgical intervention for ICH Alternative Hypothesis:H(1) Assuming clinical equipoise, i.e., no benefit in clinical outcome with early surgical intervention (null hypotheses) H(0) is correct), the ability to accelerate the patients care from the entry point to the exit point will result in a significant economic advantage to the system through cost reduction.
Impact of Cranioplasty On Cerebral Perfusion
Head InjuriesSubarachnoid Haemorrhage4 moreThe purpose of this study is to examine the impact of cranioplasty on cerebral hemodynamic and blood flow as prognostic factor in patients receiving decompressive craniectomy for Head injuries, Subarachnoid haemorrhage, intra-cerebral haemorrhage, cerebral dural sinus thrombosis, malignant middle cerebral artery stroke.
PreventIon of CArdiovascular Events in iSchemic Stroke Patients With High Risk of Cerebral HemOrrhage...
Brain IschemiaIntracranial HemorrhagesThrough this study, the investigators are to prove that Cilostazol effectively prevent cardiovascular events in ischemic stroke patients with high risk of cerebral hemorrhage, along with no significant increase in the risk of occurrence of hemorrhagic side effects. The primary hypothesis of this study is; Cilostazol alone or with probucol will reduce the risk of cerebral hemorrhage without increase of cardiovascular events compared to aspirin in the ischemic stroke patients with symptomatic or asymptomatic old cerebral hemorrhage. This study will prove the superiority of cilostazol on the prevention of cerebral hemorrhagic events without increasing the cardiovascular events against aspirin and the superiority of probucol on the prevention of overall cardiovascular events.
Longitudinal Cohort Study on ICH Care
Spontaneous Intracerebral HemorrhageIntracerebral hemorrhage [ICH] is the most feared sub-type of stroke, associated with a high mortality rate up to 50% and thus leaving large proportions of patients in functionally dependent states. In recent years randomized trials have failed to provide an effective intervention to improve functional outcome in ICH. Therefore, evidence regarding acute therapeutic interventions as well as secondary treatment approaches is still limited. The present monocentric longitudinal study on spontaneous ICH patients is based on a prospective institutional stroke registry including all hemorrhagic stroke patients treated at a German University Hospital, Department of Neurology, over a 10 year time frame (2006-2015). The main aim of this investigation, besides analyses of epidemiological aspects, will be (i) to identify possible treatment targets influencing functional outcome, and (ii) to evaluate existing therapeutic strategies in ICH care.
Emergency Management of Spontaneous Intracerebral Haemorrhage - Biomarkers
Cerebral HemorrhageThe bio-markers substudy of EsICH is designed to recruit patients with acute (first 8h) spontaneous intracerebral hemorrhage and assess a series of biological parameters (CBC, glucose, cholesterol, LDL cholesterol, triglycerides) and point-of-care bio-markers (cTnI, hsCRP, D-Dimer) in order to predict the functional outcome of these patients and to determine their input for early risk stratification and prognosis.
Diagnostic Utility of MRI in Intracerebral Hemorrhage
Cerebral HemorrhageThe overall aim of this project is to prospectively determine whether MRI can improve the conventional neuroradiological evaluation (CT with or without cerebral angiography) of patients with a spontaneous ICH or IVH. The study design will also allow us to identify the added benefit of specific MR sequences and repeat MRI in the chronic stage, thereby allowing us to prospectively determine their value in a consecutive series of patients. This information should have a major impact on the management of these patients by providing data on the diagnostic yield of routine MRI in patients presenting with a wide variety of causes for ICH or IVH. These data will help guide the diagnostic evaluation and the management of brain hemorrhage patients in the future.
Interest of Real Time Measurement of Autonomous Nervous System for the Detection of Brain Death...
Cerebral HematomaTraumatic4 moreContext: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. The aim of this project is to reduce the delay of the diagnosis of brain death, and also to improve its diagnosis in the Intensive Care Unit. The diagnosis of brain death is strictly defined by the law and relies either on two consecutive flat electroencephalograms recorded at an interval of four hours, or on the lack of cerebral circulation during a brain angiography performed after suspecting brain death on the clinical exam. However, in usual practice, it is difficult to have all the needed clinical arguments, and their interpretation can be difficult in the pathological context. This may participate in the delay and the lack of patients potentially donors. Pre-study: In a pilot study, fifty subjects with severe cerebral lesions, had a continuous ECG recording. The investigators could find that a decrease in autonomic nervous system activity, as measured through the ECG, was correlated to the transition to brain death assessed by cerebral angiography. The loss of cardiac variability was always observed between two cerebral angiographies, one before and the second after brain death. This study allowed the investigators to calculate the threshold values of sympathetic and parasympathetic activities to confirm brain death.
Association Between Haptoglobin Genotype and Brain Swelling
Intracerebral HemorrhageIntracerebral hemorrhage is bleeding into the brain and is a major cause of stroke and other complications. Brain injury from intracerebral hemorrhage occurs in two phases. The early phase involves the mechanical compression of brain tissue by the expanding hematoma. In a later phase, brain swelling develops causing further compression that may lead to brain herniation and death. This study investigates the neuroprotective role of haptoglobin, in minimizing the development of brain swelling following intracerebral hemorrhage.
