Prevention of Hypertensive Injury to the Brain by Intensive Treatment in IntraCerebral Haemorrhage...
Intracerebral HemorrhagePROHIBIT-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.
Observational Study of Safety and Outcomes After Minimally Invasive Surgery for Intracerebral Hemorrhage...
Intracerebral HemorrhageThis pilot study will examine the safety and the clinical outcomes after minimally invasive surgery (using a parafascicular technique guided by diffusion-tensor imaging) for intracerebral hemorrhage in patients selected according to evidence-based criteria. The investigators will compare 30 day and 90 day outcomes of patients who have surgery to that predicted by previously reported models for recovery after ICH, and will also describe any surgical complications related to the procedure. The investigators hypothesize that this technique will have the same mortality rate and function outcome, if not better, when compared to the outcomes predicted by previous models.
Decision Aid Feasibility Trial for Families of Critically Ill Stroke Patients
Ischemic StrokeIschaemic Stroke With Coma2 moreSevere strokes, including large artery acute ischemic stroke and intracerebral hemorrhage, continue to be the leading cause of death and disability in adults in the U.S. Due to concerns for a poor long-term quality of life, withdrawal of mechanical ventilation and supportive medical care with transition to comfort care is the most common cause of death in severe strokes, but occurs at a highly variable rate. Decision aids (DAs) are shared decision-making tools which have been successfully implemented and validated for many other diseases to assist difficult decision making. The investigators have developed a pilot DA for goals-of-care decisions for surrogates of severe, critically ill stroke patients. This was developed through qualitative research using semi-structured interviews in surrogate decision makers of traumatic brain injury patients and physicians, and adapted to severe strokes. The investigators now propose to pilot-test a DA for surrogates of critically ill severe stroke patients in a feasibility trial.
The Natural History of Procalcitonin in Hemorrhagic Stroke
Intraventricular HemorrhageIntracerebral HemorrhageApproximately 12% of strokes in the United States are hemorrhagic.1 Hemorrhagic stroke can lead to multiple complications including fever that is not infectious. Identifying the cause of fever can help physicians choose the best care for the patient to try and prevent further damage to the already injured brain. Bacterial infection is one possible cause of fever in the stroke patient; however an incorrect diagnosis of infection can lead to unnecessary antibiotic use. Better screening tools for infection are being developed to help fight the problem of antibiotic resistance and unnecessary antibiotic use. Unnecessary use of antibiotics in patients increases the risk of adverse events and overall healthcare costs. Procalcitonin (PCT) is one such screening tool which has been used previously to help tell apart bacterial and nonbacterial causes of infection in other disease states; however, PCT has not been studied in hemorrhagic stroke patients. The purpose of this study is to understand the progress of PCT in hemorrhagic stroke patients in order to see whether PCT can be a useful marker for infection in these patients.
Study on Data Acquisition and Image Characteristics of Brain Multifrequency EIT in Healthy People...
Cerebral HemorrhageCerebral Ischemia2 moreThe goal of this observational study is to compare the differences in the features of cerebral multifrequency EIT(cMFEIT) images between healthy subjects and patients with brain diseases and to explore the possibility of applying multifrequency EIT to intracranial abnormality detection.16 healthy volunteers and 8 patients with brain diseases were recruited as experimental subjects, and the cerebral EIT data of 9 frequencies in the range of 21 kHz - 100 kHz of all subjects were acquired with an EH-300 MFEIT system.
iNtrAcranial PreSsurE in Intensive Care (ICU) (SynapseICU)
Traumatic Brain InjurySubarachnoid Hemorrhage1 moreIntracranial pressure (ICP) monitoring is the most common neuromonitoring modality used in neurocritical care units (NCCU) around the world. Uncertainties remain around intracranial pressure monitoring both in traumatic and non-traumatic brain injury, and variation in clinical practice of intracranial pressure monitoring exists between neurocritical care units. The objectives of the study will explore intracranial pressure monitoring variation in practice to prioritise uncertainties in the clinical management of critical care patients with acute brain injury and support further collaborative hypotheses-based prospective studies.
Intracerebral Hemorrhage Due to Oral Anticoagulants: Prediction of the Risk by Magnetic Resonance...
Ischemic StrokeThe purpose of this study is to determine whether Magnetic Resonance Imaging may predict the risk of Intracerebral Hemorrhage for patients with ischemic stroke who receive indefinite oral anticoagulation
Stratifying Risk for Intracerebral Haemorrhage
Preterm BirthCoagulation Protein Disorders1 moreThis study aims to investigates the role of gestational age on the prevalence of coagulation factors and components of the complement system in preterm- (≤32+0 weeks) and term neonates (≥37+0 weeks) and their role for the development of brain hemorrhage.
Non-invasive Evaluation of Cerebrovascular Reactivity in Spontaneous Intracerebral Hemorrhage
Intracerebral HemorrhageSpontaneous intracerebral hemorrhage (ICH) remains a significant cause of morbidity and mortality around the globe. The most common etiology of nontraumatic spontaneous ICH is hypertensive arteriopathy (HA), while cerebral amyloid angiopathy (CAA) is the most prevalent cause of spontaneous lobar ICH in the elderly. Both HA and CAA belong to the family of cerebral small vessel disease (cSVD). cSVD involves pathological processes that affect the arteries, arterioles, capillaries, and veins on the surface and beneath the brain. The resultant changes of cSVD in the brain vasculatures can be detected with neuroimaging, includes cerebral microbleeds, white matter hyperintensities, lacunes, dilated perivascular spaces, and brain atrophy. Investigators of this study have probe into various imaging markers in patients with cSVD. Investigators found that the lacune and cerebral microbleeds location was related to distinct underlying etiology of cSVD. Further, investigators utilized amyloid PET study to directly quantified the cerebral amyloid burden, and demonstrated the correlation between amyloid deposition and deep/superficial microbleeds ratio. The association between cerebellum microbleeds, which is a novel marker for cSVD, and the underlying pathology in patient with spontaneous ICH has been investigated. Investigators also summarized and published the current research of different cSVD imaging markers and its implication on patient care. Cerebrovascular reactivity (CVR) represents the phenomenon that cerebral vessels dilate or constrict in response to stimuli, which provides insights into the vascular reserve information. The vascular reserve parameter is complementary to steady-state vascular index, such as cerebral perfusion or other neuroimaging markers. Measurement of CVR using advanced MR techniques is an emerging technique with multiple potential clinical utilities, and impaired autoregulation may contribute to the pathogenesis of cSVD. Recently, diminished CVR under visual stimuli has been linked to vascular amyloid deposits and related vascular dysfunction. Clarifying the mechanism of cSVD-related brain injury would be an important step towards identifying candidate treatment approaches. The goal of this study is to understand the features of CVR in patients with cSVD-related spontaneous ICH, for the purpose of establishing new biomarkers in cSVD diagnosis and understanding the underlying pathophysiology.
