Filter by:The aim of this pilot study is to provide an assessment of safety and feasibility of early minimally invasive image guided endoscopic hematoma evacuation (within 24 hours of symptom onset) in patients suffering from intracerebral haemorrhage (ICH).
The investigators design a retrospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective, treatments and prognosis of Chinese hospitalized adult patients with intracerebral hemorrhage.
The intracerebral hemorrhage study is a multicenter , combination of prospective and retrospective observational cohort study led by Dr. Muhammad Junaid Akram, PhD scholar at Chongqing Medical University. Prof Dr. Qi Li will be the senior consultant for the study. The study will be focusing on natural history, epidemiological , radiological, rehabilitative and clinical aspects as well as the effect of various treatments on the hemorrhagic patients. The study related data of the patients diagnosed with intracerebral hemorrhage will be collected in prospective and retrospective ways. The prognostic data for the patients will be assembled and collected via using different outcome measures at different points of time.
In this protocol, the investigators present methods and preliminary results from the PLATFORM-CVD Study, an EHR-based multicenter cohort. This study will focus on assessing the distribution of major cerebrovascular diseases, determining the risk factors associated with disease incidence and worse in-hospital outcomes, as well as describing the quality of care. Data from this cohort will be used to develop suitable prediction models for cerebrovascular diseases using real-world data and to understand how outcomes for cerebrovascular diseases would change with quality improvement interventions.
The purpose of this research study is to determine whether blood pressure treatment regimens with spironolactone are better than blood pressure treatment regimens without spironolactone at lowering blood pressure in stroke survivors.
Cerebral amyloid angiopathy-related intracerebral (CAAH) hemorrhage is second factor of primary intracerebral hemorrhage. However, no effective prevention and treatment strategies have been established. Remote ischemic conditioning is a neuroprotective strategy. In animal studies，RIC is efficiency in accelerating the absorption of hematoma. Therefore, the investigators plan to carry out this research to evaluate the safety and efficacy of RIC in patients with CAA related ICH.
Intracerebral hemorrhage is increasingly becoming a major burden in the society because of significant morbidity as well as mortality. Hematoma volume at the time of presentation as well as hematoma expansion and re-bleed or ongoing bleed further deteriorates the patient making a poor prognosis, however at present no therapy targets this pathological process. Though clinical studies do report benefit of using tranexamic acid in spontaneous intracerebral hemorrhage by reducing hematoma expansion rate as well as decreasing ongoing bleed, large randomized controlled trials have not shown any convincing advantage owing to various limitations in their design and methods. However, they uniformly did not find any significant side effect with the use of tranexamic acid. The aim of this study is to test the hypothesis that intravenous tranexamic acid is superior to placebo by reducing hematoma expansion when given within 24 h of spontaneous intracerebral hemorrhage.
Approximately 20% of patients with mild head injury presenting to the Emergency Department (ED) is taking antiplatelet agents and 10% is taking oral anticoagulants. The aim of the study is to determine the prevalence of cerebral hemorrhage in patients presenting to the ED with an MHI. It also aims to determine whether the use of antiplatelet agents and anticoagulants may be a risk factor for the occurrence of cerebral hemorrhage and mortality. This is a prospective observational study that will include all patients who present to ED at Gemelli Hospital for an MHI for 2 years. Patients will be divided into four groups according to whether or not they are taking anticoagulants and antiplatelet drugs. Groups will be compared to evaluate the possible increased risk of complications in patients on treatment and among the different medications.
Theoretical Framework & Background Cortical spreading depressions (CSD) and seizures, are crucial in the development of delayed cerebral ischemia and poor functional outcome in patients suffering from acute brain injuries such as subarachnoid hemorrhage. Multimodal neuromonitoring (MMNM) provides the unique possibility in the sedated and mechanically ventilated patients to record these electrophysiological phenomena and relate them to measures of cerebral ischemia and malperfusion. MMNM combines invasive (e.g. electrocorticography, cerebral microdialysis, brain tissue oxygenation) and noninvasive (e.g. neuroimaging, continuous EEG) techniques. Additionally, cerebral microdialysis can measure the unbound extracellular drug concentrations of sedatives, which potentially inhibit CSD and seizures in various degrees, beyond the blood-brain barrier without further interventions. Hypotheses 1. Online multimodal neuromonitoring can accurately detect changes in neuronal metabolic demand and pathological neuronal bioelectrical changes in highly vulnerable brain tissue. 2. Online multimodal neuromonitoring can accurately detect the impact of pathological neuronal bioelectrical changes on metabolic demand in highly vulnerable brain tissue. 3. The occurrence and duration of pathological neuronal bioelectrical changes are dependent on sedatives and antiepileptic drug concentrations 4. The occurrence and duration of pathological neuronal bioelectrical changes have a negative impact on functional and neurological long-term patient outcome. 5. Simultaneous invasive and non-invasive multimodal neuromonitoring can identify a clear relationship of both methods regarding pathological neuronal bioelectrical changes and metabolic brain status. Methods Systematic analysis of MMNM measurements following standardized criteria and correlation of electrophysiological phenomena with cerebral metabolic changes in all included patients. In a second step neuroimaging, cerebral extracellular sedative drug concentrations and neurological functional outcome, will be correlated with both electrophysiologic and metabolic changes. Due to numerous high-resolution parameters, machine learning algorithms will be used to correlate comprehensive data on group and individual levels following a holistic approach. Level of originality Extensive, cutting edge diagnostic methods are used to get a better insight into the pathophysiology of electrophysiological and metabolic changes during the development of secondary brain damage. Due to the immense amount of high-resolution data, a computer-assisted evaluation will be applied to identify relationships in the development of secondary brain injury. For the first time systematic testing of several drug concentrations beyond the blood-brain barrier will be performed. With these combined methods, we will be able to develop new cerebroprotective treatment concepts on an individual basis.
