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). 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. 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. 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. A Study to Evaluate Sex and Gender in Multiple System Atrophy Rochester, Minn. The primary purpose of this study is to understand the influence of sex and gender on pathophysiologic mechanisms of neurodegeneration in Multiple System Atrophy (MSA) in order to determine sex-specific hormonal factors associated with onset of symptoms in MSA. Peripheral Nerve Stimulation Therapy for Atrial Fibrillation Rochester, Minn. The purpose of this study is to determine and compare the safety and efficacy of transcutaneous afferent patterned stimulation (TAPS) and respiratory-gated auricular vagal afferent nerve stimulation (RAVANS) therapies for the reduction of paroxysmal atrial fibrillation (AF) burden. Blood and Spinal Fluid Collection for Research Studies in Motor Neuron Disease and Motor Neuropathy Rochester, Minn. The purpose of this study is so that blood (plasma and blood cells) and/or extra spinal fluid (which was taken for clinical purposes) can be obtained and stored for later research on a large cohort of patients with progressive motor neuronopathies and neuropathies, many of which will be determined to suffer from Amyotrophic Lateral Sclerosis (ALS). Treatment of Brain AVMs (TOBAS) Study Jacksonville, Fla. The purpose of this study is to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty. Advanced Care Planning in Dementia Jacksonville, Fla. The goal of this study is to gain a better understanding of the status of advanced care planning among caregivers of patients with dementia and examine how this differs by race and disease stage. A Study of the Possible Use of a New Imaging Method with Glioma Tumors Rochester, Minn. The purpose of this study is to see if Magnetic Resonance Elastography (MRE) a recently developed imaging technique can be used to characterize and help stage glioma tumors and evaluate response to therapy.
