Filter by:This study is being done to see if adding GLIADEL to the site where the tumor was removed works as well as just having the tumor removed with radiation treatment done within six weeks after the surgery to keep the cancer from coming back.
To investigate the glutaminergic system in the onset of migraine-like attacks.
This phase II trial studies how well anakinra works in preventing severe chimeric antigen receptor T-cell-related encephalopathy syndrome after chimeric antigen receptor T-cell therapy in patients with large B-cell lymphoma that has come back or has not responded to treatment. Immunosuppressive therapy, such as anakinra, is used to decrease the body?s immune response, which may prevent severe chimeric antigen receptor T-cell-related encephalopathy syndrome.
The study will evaluate whether sensory flicker can modulate neural activity of deep brain regions in humans, and whether it can have relevant effects on behavior. Moreover, it will compare those effects to the gold-standard method of modulating brain circuits, direct electrical stimulation of the brain (the same mechanism as deep brain stimulation), using a powerful within-subjects design.
Children with acquired brain injury (ABI) often struggle with complex impairments, including cognitive (such as memory and attention), social, emotional and behavioral challenges. There is broad agreement that there is a lack of evidence-based knowledge about rehabilitation for children with ABI in the chronic phase. The current study is a feasibility study of a planned randomized controlled trial (RCT), the CICI-intervention, directed towards children with ABI and their families in the chronic phase. The feasibility study aims to evaluate the study protocol, the assessment procedures and the technical solutions prior to performing the RCT. A feasibility study with six participating children and families will be conducted in close collaboration with schools and local health care providers. The intervention to be tested (the CICI-intervention) focuses on the child's and family's individually identified target outcome areas to be addressed, with corresponding rehabilitation goals. The intervention aims to enhance everyday functioning in the home and school environment by reducing ABI-related symptoms, and by attaining rehabilitation goals in areas noted as challenging by the participants. In the future RCT-study the efficacy of the CICI-intervention will be measured in terms of goal attainment, community participation, cognitive, behavioral, social, and family functioning.
The TIME study is a randomized, controlled trial to evaluate impact on early measures of neurodevelopment and the safety profile of therapeutic hypothermia in term neonates with Mild Hypoxic-Ischemic Encephalopathy who are < 6 hours of age. Neurodevelopmental outcome will be assessed at 12-14 months of age. The study will enroll 68 neonates randomized to therapeutic hypothermia or normothermia across 5 centers in California.
Efficacy and Safety of Nitazoxanide in preventing recurrence of Hepatic Encephalopathy.
The HIV/HEART Aging study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to October 2019 (12,5 year Follow-up) 1806 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.
Individuals with cirrhosis are likely to develop overt hepatic encephalopathy for which diagnostic modalities and treatment options are limited. The purpose of this study is to determine if individuals with cirrhosis who experience hepatic encephalopathy would benefit from investigational microbiota restoration therapy due to their inherent cognitive alterations. Analysis for a correlation between changes in microbiome composition and specific blood biomarkers could allow for earlier diagnosis of HE which could then be treated earlier and with novel treatments.
Introduction Liver cirrhosis (LC) is irreversible fibrosis of the liver (1) and it remains a public health problem. One of the complications of the cirrhosis is hepatic encephalopathy (HE) which is defined as brain dysfunction caused by liver insufficiency. Pathophysiological mechanisms of HE are complex and multifactorial. Recognition of beginning stages of HE, such as minimal HE (mHE) is of most importance. Objectives and originality of the project Diagnosis of mHE can be challenging, time-consuming and, at least to some extent, subjective. This project will assess the role of magnetic resonance (MR) in mHE diagnosis with emphasis on multimodal imaging technique. With advanced magnetic resonance (MR) techniques, in-vivo detection of intracellular water content, estimation pH and metabolites levels with millimolar concentrations can be easily performed. This will offer to explore possible pathophysiological mechanisms of HE and to evaluate the results from previous, studies that were mainly performed on animal models or cell cultures. By our best knowledge, multimodal MR approach as the investigators propose in this application has not been yet performed. The investigators will use advanced MR techniques which are currently not available in the clinical setting and require multicenter collaboration. Methods The investigators will include 10-20 patients of both genders with hyperammonemia and mHE and 10-20 patients of both genders with HE. Diagnosis of HE will be made based on results of validated neuropsychiatric test. Age-matched and gender-matched control group with no gastrointestinal, neurological or psychiatric complaints and normal levels of ammonia in the blood. Patients with mHE/HE will be included from outpatient clinic of the Department of gastroenterology, University Medical Centre (UMC) Ljubljana. Healthy controls (HC) will be invited to join via internet advertisement. Contraindications for HC will include gastrointestinal (emphasis on liver disease), neurological or psychiatric complaints. Grade of mHE/HE will be classified according to West-Haven (WH) classification. Patients with different degree of liver cirrhosis, which will be scored with the Child-Pugh (CP) score, and with no contraindications for MR (e.g. presence of metal in body) will be included. Blood levels of liver enzymes and ammonia will be measured in all participants. MR scanning will include: T1- and T2-weighted MR, MRS (MEGA-PRESS and PRESS) in two voxels: striatum and cerebellum. Location will be double-checked by voxel position screenshots. Analysis, with voxel-positioning error compensation will be performed in Gannet (www.gabamrs.com). Moreover, high resolution diffusion weighted imaging (DWI), diffusion kurtosis imaging (DKI), quantitative susceptibility mapping (QSM) will be performed in brain as well. Liver QSM will be executed to assess iron load.
