A Study to Establish a Parkinson’s Disease (PD) Cohort using the Parkinson’s Progression Markers Initiative (PPMI) Scottsdale/Phoenix, Ariz. The Parkinson Progression Marker Initiative (PPMI) is a study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson’s disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability. Magnetic Resonance Elastography of Dementia Rochester, Minn. The purpose of this study is to develop and test the effectiveness of an investigational imaging technique called magnetic resonance elastography (MRE) to measure the stiffness (mechanical properties) of tissues. Coordinated, Collaborative, Comprehensive, Family-based, Integrated, Technology-enabled Stroke Care Jacksonville, Fla. C3FIT’s overall goal is to assess if patient outcomes are improved when the Comprehensive and Primary Stroke Center (CSC/PSC) system is supplemented with an Integrated Stroke Practice Unit (ISPU) system of care, a patient-centric model of care involving the patient and caregiver/family that coordinates care from the acute management through the rehabilitation and recovery of the patient. A Study of Vaccine Therapy in Treating Patients with Malignant Peripheral Nerve Sheath Tumors that are Recurrent or Cannot Be Removed by Surgery Rochester, Minn. The purpose of this study is to assess the side effects and best dose of a genetically engineered measles virus for treating patients who have a cancerous peripheral nerve sheath tumor that cannot be removed by surgery (unresectable) or that has come back after a period of improvement (recurrent). A Study to Evaluate Advanced Development of Desorption Electrospray Ionization Mass Spectrometry for Intraoperative Molecular Diagnosis of Brain Cancer Jacksonville, Fla. The purpose of this study is to explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to identify cancerous versus noncancerous tissue and estimate the percentage of tumor infiltration in tissue biopsies, by monitoring depletion of N-acetylaspartate (NAA) and aberrations of the phospholipid signature of neurological tissue; and to identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and, therefore, differentiate between IDH-mutant and wild-type gliomas. Human Blood and Tissues Repository for Neuroscience Research Jacksonville, Fla. The purpose of this study is to collect adult human blood, cerebrospinal fluid, brain, and spine tissues/fluids at time of surgery in order to conduct future studies of the cellular mechanisms of tissue invasion utilized by brain and spine tumors of the central nervous system (CNS). Arizona Alzheimer’s Disease Research Center (ADRC-001) Scottsdale/Phoenix, Ariz. There is evidence that neurodegenerative changes precede clinical symptoms in Alzheimer’s disease by two decades (Villemagne et al, 2013). Early detection is critical for development of interventions to halt, slow, or even reverse these pathological processes. The promise of plasma biomarkers to identify early pathology is growing rapidly (Palmqvist et al, 2020), however it is likely that multiple converging biomarkers will be necessary to identify the earliest pathological changes, as subtle differences from healthy controls may fall within the margin of error for any given single biomarker measure. Here we propose that the evaluation of speech and language for both baseline (cross-sectional) and longitudinal changes (within-participant) may add significant value to early pre-clinical pathological changes in MCI and AD. This is bolstered by emerging evidence of the relationship between language characteristics and amyloid burden (Verfaillie et al, 2019) and the large literature that characterizes language-use differences and deficits across the spectrum of cognitive decline (e.g., Mueller et al, 2018). We propose to add a series of in-clinic language elicitation tasks that allow for automated assessment of relevant speech and language domains and to validate these measures cross-sectionally and longitudinally relevant to neuropsychological, blood, and PET biomarkers. Testing the Addition of an Anti-cancer Drug, Selinexor, to the Usual Chemotherapy Treatment (Temozolomide) for Brain Tumors That Have Returned After Previous Treatment Rochester, Minn., Scottsdale/Phoenix, Ariz., Jacksonville, Fla. The purpose of phase 1 of this trial is to determine the maximum tolerated dose of temozolomide followed by selinexor in recurrent glioblastoma patients as determined by dose-limiting toxicities [DLTs] and the total toxicity profile. The purpose of phase 2 of this trial is to evaluate the effectiveness of sequentially administering temozolomide and selinexor in recurrent glioblastoma as determined by progression-free survival [PFS]. A Study of the Drugs Selumetinib Versus Carboplatin/Vincristine in Patients With Neurofibromatosis and Low-Grade Glioma Rochester, Minn. The pupose of this study is to evaluate whether or not selumetinib works just as well as the standard treatment with carboplatine/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine. Memantine Hydrochloride and Whole-Brain Radiotherapy With or Without Hippocampal Avoidance in Reducing Neurocognitive Decline in Patients With Brain Metastases Mankato, Minn., La Crosse, Wis., Eau Claire, Wis., Rochester, Minn., Albert Lea, Minn. This randomized phase III trial compares memantine hydrochloride and whole-brain radiotherapy with or without hippocampal avoidance in reducing neurocognitive decline in patients with cancer that has spread from the primary site (place where it started) to the brain. Whole brain radiotherapy (WBRT) is the most common treatment for brain metastasis. Unfortunately, the majority of patients with brain metastases experience cognitive (such as learning and memory) deterioration after WBRT. Memantine hydrochloride may enhance cognitive function by binding to and inhibiting channels of receptors located in the central nervous system. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Using radiation techniques, such as intensity modulated radiotherapy to avoid the hippocampal region during WBRT, may reduce the radiation dose to the hippocampus and help limit the radiation-induced cognitive decline. It is not yet known whether giving memantine hydrochloride and WBRT with or without hippocampal avoidance works better in reducing neurocognitive decline in patients with brain metastases. التصفّح دراسات سريرية السابقالصفحة السابقة توجّه للصفحة 33 توجّه للصفحة 44 توجّه للصفحة 55 توجّه للصفحة 66 توجّه للصفحة 77 التاليالصفحة التالية المتخصصون في المجالات الطبية Neurology & Neurosurgery clinical-trials
