Active clinical trials for "Cerebral 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.

Change and effect of cerebral autoregulation during targeted temperature management in neurocritical patients

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.

Fall with head injury is becoming an epidemic challenge especially with the ageing population. Contributing factors for mortality and poor functional outcome included development of cerebral contusion and delayed traumatic intracerebral haematoma. There is a higher prevalence especially with the increasing use of antiplatelets and anticoagulants. Non-invasive monitoring such as near-infrared spectroscopy (NIRS) is sensitive in detecting intracranial changes. The role and efficacy of this non-invasive method has not been specifically established in patients with head injury as an initial non-operative monitoring. This is particular important in the setting of a general ward in which nursing staff is limited. The advantages of these noninvasive monitoring might have a role of continuous neuro-monitoring. They can also potentially reduce the number of unnecessary repeated CT Brain in the context of limited radiology staff and resources. Timely detection and treatment of this condition accordingly is crucial. Potential options of non-invasive monitoring such as nearinfrared spectroscopy (NIRS) is to be investigated. The aim of this study is to determine the sensitivity and specificity of NIRS as a non-invasive monitoring in detecting delayed intracranial injuries in comparison with the Gold Standard CT Brain. Study design is Prospective sensitivity and specificity study of Near Infra-red Spectroscopy (NIRS) as a non-invasive monitoring in detecting delayed intracranial injuries in comparison with the Gold Standard CT Brain in Hong Kong Chinese. Consecutive patients admitted to Prince of Wales Hospital, Hong Kong would be recruited. Outcome measures including correlation of non-invasive monitoring with near-infrared spectroscopy (NIRS) to CT Brain findings including any increase in haematoma size, cerebral edema or mass effect. Secondary outcome including 30 days mortality and functional outcome at 3 months.

The Chongqing intracerebral hemorrhage study is a multi-center, prospective, observational study led by professor Qi Li from Chongqing Medical University. Professor Peng Xie will be the senior consultant for the study. The Chongqing intracerebral hemorrhage study will focus on the epidemiology, natural history, pathogenesis, laboratory, radiological aspects, clinical outcomes and the effects of treatment in patients with intracerebral hemorrhage. The clinical, laboratory, imaging, genetic and outcome data of patients diagnosed with acute intracerebral hemorrhage will be prospectively collected. The prognosis of patients with intracerebral hemorrhage will be assessed by using several outcome measure scales at different time points.

This observational, retrospective, single-arm, multi-centre cohort study will use real-world data (RWD) to develop real-world evidence (RWE) of the safety and clinical effectiveness of the Pipeline™ Flex Embolization Device with Shield Technology™ in Australian patients that have received a flow diversion device to treat an intracranial aneurysm (IA). The medical records from 500 procedures completed at Gold Coast University Hospital in Queensland (QLD), Prince of Wales Hospital in New South Wales (NSW), and Sir Charles Gardiner Hospital in Western Australia (WA), will be analysed. The study will report the risk and likelihood of stroke (ischaemic and haemorrhagic), delayed neurological adverse events and incomplete aneurysm occlusion within sub-groups of the patient cohort and determine the predictive or confounding factors that influence clinical outcomes under pragmatic or 'real-world' conditions.

The investigators retrospectively reviewed the electronic medical records of the patients with spontaneous cerebral hemorrhage and mechanical valves from 2015 to 2020 in the second affiliated hospital of Zhejiang university medical college. Medical documents and patient data were reviewed, including patient age, gender, type of mechanical heart valve, replacement time, replacement site, underlying disease, anticoagulant drugs at admission, type of cerebral hemorrhage, treatment mode, time without anticoagulant, length of stay, mortality, etc

The purpose of this study is to Early identify patients based on clinical manifestation, imaging, gene and histology, explore diagnostic tools get gene repertoire of Chinese Build a cerebral amyloid angiopathy (CAA) prospective cohorts, observing the disease history, and exploring prognostic factors of hemorrhage in CAA patients

The primary objective of this multicenter study is to validate the AVICH score in terms of patient outcome prediction in AVM patients with associated ICH. Secondary objectives are the impact of pretreatment of the AVICH score. Patients outcome is measured using the modified Rankin Scale (mRS) and are grouped in favorable (mRS score, 0-2) and unfavourable (mRS score, 3-6) outcome at last follow-up (LFU). The following parameters, which are part of the AVICH score, will be compared between the 2 groups: ICH score including age, Glasgow Coma Scale (GCS) score, haemorrhage volume, presence of intraventricular hemorrhage (IVH), and localization of the ICH. Spetzler-Martin grade including AVM size, eloquent location, and venous drainage, as well as the Lawton-Young grade, including age, presence of ruptured AVM, and the nidus structure. In addition pre-/postruptured treatment modalities, including embolization, radiotherapy, surgery or no treatment will be analysed. Outcome (mRS) at 3 months, at 1 year, and at LFU will be compared. Multicentre validation study Key inclusion criteria: All patients with ICH associated AVMs and a modified Rankin Scale <2 (so 0-1) before hemorrhage Pretreatment (embolization, radiosurgery, surgery) before ICH is not an exclusion criteria. Key exclusion criteria: incomplete data set AVM Patients with only subarachnoid hemorrhage (SAH) or IVH and no ICH

A population-based registry in Catalonia of patients with acute spontaneous Intracerebral Hemorrhage, to investigate whether type of center and time from onset to admission is associated with functional outcome and mortality.
