Active clinical trials for "Intracranial Hemorrhages"

The study is an observational prospective evaluation of an approved and unchanged clinical management, evaluating different diagnosis methods to assess brain perfusion in patients with an aneurysmal or AVM-related intracranial hemorrhage

This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The purpose of the study is to assess the impact of an Artificial Intelligence (AI) tool called qER 2.0 EU on the performance of readers, including general radiologists, emergency medicine clinicians, and radiographers, in interpreting non-contrast CT head scans. The study aims to evaluate the changes in accuracy, review time, and diagnostic confidence when using the AI tool. It also seeks to provide evidence on the diagnostic performance of the AI tool and its potential to improve efficiency and patient care in the context of the National Health Service (NHS). The study will use a dataset of 150 CT head scans, including both control cases and abnormal cases with specific abnormalities. The results of this study will inform larger follow-up studies in real-life Emergency Department (ED) settings.

Introduction Remote cerebral hemorrhage following reperfusion treatment in ischemic stroke is rare (1.3-3.7% of all treated strokes) and is associated with worse functional and vital prognosis. Multicenter observational studies suggest that amyloid angiopathy may be one of the main risk factors for remote hemorrhage. Currently, it is unknown what happens to those patients with remote hemorrhage beyond 3 months of follow-up in terms of risk/benefit balance when receiving antiplatelet or anticoagulant therapy, as well as from a cognitive point of view. Considering an analogy with amyloid angiopathy, the hypothesis is that those patients with remote hemorrhage have a higher risk of intracranial hemorrhage during follow-up when receiving stroke secondary prevention, and will also present greater cognitive deterioration during long-term follow-up. Main Objectives To explore the frequency and risk factors for intracranial hemorrhage during follow-up of patients with remote cerebral hemorrhage. To explore the frequency and progression of cognitive deterioration during follow-up in patients with remote cerebral hemorrhage. Methodology Observational, prospective, multicenter registry with a population-based case-control design of consecutive patients with remote hemorrhage following reperfusion therapy in acute ischemic stroke. Inclusion criteria: Diagnosis of ischemic stroke with age greater than or equal to 18 years who has remote cerebral hemorrhage after receiving reperfusion therapy in the acute phase. Exclusion criteria: Lack of basic data (age, sex, neuroimaging data) or telephone for follow-up. The cases will be those patients with remote hemorrhage. For each case included, 4 consecutive controls will be included (2 with local parenchymal hemorrhagic transformation and 2 without hemorrhagic transformation). The data will be filled out within the (Codi Ictus de CATalunya) CICAT registry form (currently mandatory in all stroke centers in Catalonia) to which additional variables will be added. Telephone follow-up will be conducted at 3, 12, and 24 months. Main study variable: Any type of spontaneous or traumatic intracranial hemorrhage during a 24-month follow-up. Score on the "Short Informant Questionnaire" scale (a validated 17-question questionnaire to be conducted over the phone, where a score higher than 57 points indicates cognitive impairment). Expected sample size during a 2-year recruitment period: 105-300 patients (considering the participating centers to date). Additional information. This study is endorsed by the "Pla Director de la Malaltia Vascular Cerebral" in Catalonia. Participating Centers. Participation offers have been sent to the 28 hospitals in the hospital network of Catalonia with the capacity to administer intravenous fibrinolysis. Positive responses have been received from 13 of them so far. In case the project is accepted by the (Comité Ético de Investigación Clínica) CEIC Sant Pau, the centers that have not responded will be contacted again to obtain their participation.

The purpose of this dose-ranging pilot study is to compare Recombinant Activated Factor VII, Prothrombin Complex Concentrate and Fresh Frozen Plasma (each starting at low doses with escalation if necessary) for the reversal of warfarin in the setting of acute intracranial hemorrhage.

To analyze the influence of early hematoma morphology on hematoma expansion, optimize the treatment plan for cerebral hemorrhage, and guide the treatment of patients with cerebral hemorrhage in combination with clinical practice.

The objective of this study is to determine if the administration of platelets will improve outcome in patients with ICH who are being treated with either aspirin, a thienopyridine (ticlodipine, clopidogrel, prasugrel) or a combination of both. The study has four specific aims: To determine what affect platelet administration will have on bleeding in the brain. To determine what affect platelet administration will have on brain function. Several assessments to test the functioning of the brain will be performed at enrollment and throughout the study. Comparing the results of these assessments between the experimental and control groups should allow us to determine if platelet administration improves outcomes in patients with bleeding in the brain exposed to antiplatelet therapy. An important risk of reversing antiplatelet therapy is exposing the patient to the very complications this therapy was designed to prevent. Therefore, tracking complications will be a very important part of this study. The investigators will compare the rates of death, heart attack, stroke and clots in the veins between groups. Some patients (10-40%) have limited responsiveness to antiplatelet therapy. While platelet responsiveness, as measured by a special platelet blood test, will not affect enrollment, the investigators feel it will be important to measure.

Primary Objective: To determine the effects of a diabetes specific enteral formula compared to a standard formula supplemented with protein (isocaloric and isonitrogenous) on the mean blood glucose and glycemic variability in a homogenous group of critically ill patients in a neurological ICU. Blood glucose will be recorded every minute using a continuous blood glucose monitor. The primary end points will be the difference between the mean blood glucose levels and the glucose variability between the control and intervention groups for the time period that the patient is in the ICU and receiving tube feeds and for up to a maximum of 14 days. Secondary Objectives: To determine the effects of the diabetes specific versus standard tube feeds on the change in muscle thickness and volume measured by 2-dimensional ultrasound imaging during the patients ICU stay.

This is a follow-up study of the open label, single-center, phase I clinical trial to evaluate the safety of Pneumostem® in premature infants with Intraventricular hemorrhage.

Fever, defined as temperature higher than 38.3C (100.9 F), is common in patients with head injuries and is associated with poor recovery after injury. The current standard of care is to use oral acetaminophen (Tylenol) followed by a body cooling device. This method can effectively reduce fever but results in a high rate of shivering. Shivering is stressful to the heart and can further worsen brain injury. Methods to combat shivering have been developed and are successful in limiting the stress in the majority of patients that use a body cooling device. However, the drugs used to control shivering are sedating and may also interfere with brain recovery. The purpose of this study is to assess whether ibuprofen given intravenously is more effective in combating fever than the current standard of care. Should results from this study demonstrate that ibuprofen infusion is effective, a larger study will be conducted to determine whether this aggressive fever control regimen leads to improved recovery after brain injury.

The purpose of this project is to quantify normal and abnormal skin blood flow regionally in different areas of the body(face, extremities, over burns and wounds) at baseline and over time in response to treatment or environmental changes, such as temperature, light and pressure.
