Active clinical trials for "Hemorrhage"

Small bowel capsule endoscopy (SBCE) has become an important tool in clinical practice since its introduction in 2000. This non-invasive method allows the visualization of small bowel mucosa, being essential in the management of many conditions, such as suspected small bowel bleeding, inflammatory bowel diseases and intestinal polyposis syndromes. Despite recommendations concerning SBCE in different pathologies, there are still some technical concerns to be addressed. The optimal preparation for SBCE has been one of these controversial issues. Currently, the European Society of Gastrointestinal Endoscopy (ESGE) recommends that patients ingest a purgative agent (2L of polyethylene glycol, PEG) and antifoaming agents for SBCE, because it was associated with a better visualization. However, it remains unclear which is the optimal timing for purgative use. Furthermore, the use of a booster agent after capsule ingestion is already performed in colon capsule endoscopy, but less is known about its application in SBCE. Also, it remains to be clarified whether a better visualization results in higher diagnostic yield and impacts patients' outcomes. Therefore, the global aim of this prospective, randomized, multi-centric study is to determine the optimal timing and preparation for small-bowel capsule endoscopy (regardless of the equipment used), comparing four groups of different preparation protocols: Protocol 1) 1L of Moviprep® solution the night before the procedure Protocol 2) 1L of Moviprep® solution up to 2h before the procedure Protocol 3) 0.5L of Moviprep® solution up to 2h before the procedure plus 0.5L of Moviprep® solution after the capsule had reached the duodenum (assessed with real-time viewer) Protocol 4) 1L of Moviprep® solution after the capsule had reached the duodenum (assessed using real-time viewer)

The goal of this clinical trial is to explore the effect of FDA-approved antiseizure drugs in the brain connectivity patterns of severe acute brain injury patients with suppression of consciousness. The main questions it aims to answer are: Does the antiseizure medication reduce the functional connectivity of seizure networks, as identified by resting state functional MRI (rs-fMRI), within this specific target population? What is the prevalence of seizure networks in patients from the target population, both with EEG suggestive and not suggestive of epileptogenic activity? Participants will have a rs-fMRI and those with seizure networks will receive treatment with two antiseizure medications and a post-treatment rs-fMRI. Researchers will compare the pretreatment and post-treatment rs-fMRIs to see if there are changes in the participant's functional connectivity including seizure networks and typical resting state networks.

Non-Contrast Computed Tomography (NCCT) of the head is the most common imaging method used to assess patients attending the Emergency Department (ED) with a wide range of significant neurological presentations including trauma, stroke, seizure and reduced consciousness. Rapid review of the images supports clinical decision-making including treatment and onward referral. Radiologists, those reporting scans, often have significant backlogs and are unable to prioritise abnormal images of patients with time critical abnormalities. Similarly, identification of normal scans would support patient turnover in ED with significant waits and pressure on resources. To address this problem, Qure.AI has worked to develop the market approved qER algorithm, which is a software program that can analyse CT head to identify presence of abnormalities supporting workflow prioritisation. This study will trial the software in 4 NHS hospitals across the UK to evaluate the ability of the software to reduce the turnaround time of reporting scans with abnormalities that need to be prioritised.

Major liver resection is associated with substantial intraoperative blood loss and subsequently blood transfusions. Blood transfusion in elective liver surgery is a significant factor of perioperative morbidity and mortality, as well as possibly long-term oncologic outcome. The purpose of this study is to use whole blood phlebotomy to decrease the central venous pressure, resulting in a state of relative hypovolemia. It is hypothesized that this intervention will lead to a decrease in blood loss at the time of liver resection and thus reduced blood transfusion in major liver surgeries.

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.

TCM is an essential context of the ICH management in Chinese culture. Given the potential benefits of Chinese herbal medicine FYTF-919 in reducing haematoma and bleeding after acute ICH from fundamental research and small clinical studies, more reliable evidence is required to guide ICH treatment using TCM. This study aims to determine the effectiveness and safety of TCM in a larger sample of patients with moderate-severe ICH and provide evidence for TCM clinical guidelines on ICH management. The presumed mechanism of action is in promoting the reabsorption of the haematoma and perihematomal oedema in ICH.

The Neuroendoscopic, Trans-occipital Approach Evacuation of Acute Hypertensive Cerebral Hemmorrhage Combined Low-drainage Surgery: a Multi-center Clinical Trial

The investigators will perform follow-up on 250 of 500 cases recruited into the ROSE study of cases with deep and lobar intracerebral hemorrhage to perform advanced neuroimaging at 12-24 months post stroke, and evaluations of motor and cognitive function at baseline, 6 months after baseline, and 12 months after baseline to determine predictors of recovery, progressive cognitive or functional impairment. The investigators propose to leverage the recruitment, DNA, RNA-seq and baseline advanced neuroimaging cohort of ROSE to obtain long-term neuroimaging and identical assessments longitudinally to address critical questions regarding the progressive decline of patients 12 to 24 months post intracerebral hemorrhage (ICH) with long term cognitive follow-up to 36 months on average. This proposal would represent the largest, and longest advanced neuroimaging and RNA-sequencing evaluation after ICH to date.

The study aims to compare the effect of addition of verapamil and Bisoprolol to general anasthesia aimed reduction in heart rate and blood loss during endoscopic sinus surgery.

Neuropsychological and functional long-term consequences of subarachnoid hemorrhages (SAH) represent a great challenge, since sometimes considerable cognitive deficits occur without evidence of substantial brain damage. In this study, we want to examine if the frequently observed memory deficits are associated with hippocampal atrophy.
