Stellate Ganglion Block For Refractory Raynaud’S Phenomenon- A Case Report, William J. Naber Ii, Derik J. Scribner, Gabriel Howard

Graduate Medical Education Research Journal

Introduction: Raynaud’s phenomenon (RP) is predominately a sympathetically mediated ischemic vasospastic disease involving the distal limbs and is associated with sharp pains, numbness, and dermatological color changes. The symptoms are commonly induced by cold weather, stress, and trauma and it is known to affect 4.85% of the population. There are few well-defined treatments for patients with RP that are refractory to 1st-line therapies. We present a case of intractable RP with corresponding response to stellate ganglion block (SGB) which demonstrates the efficacy profile and safety of SNS blocks in treatment of resistant RP.

Power Training Improves The Sensorimotor Cortical Oscillations In Youth With Cerebral Palsy, Morgan Busboom, Anna Reelfs, Mike Trevarrow, Brad Corr, Heidi Reelfs, Sarah Baker, Hannah Bergwell, Tony W. Wilson, Max J. Kurz

Child Health Research Institute Pediatric Research Forum

Background: Our magnetoencephalographic (MEG) brain imaging studies have shown that youth with cerebral palsy (CP) demonstrate altered sensorimotor beta (18-24Hz) cortical oscillations when controlling their leg motor actions and these anomalous cortical oscillations are linked with the extent of their mobility impairments. Current therapeutic trends for improving mobility have shifted from strength training to high-velocity power training, which has shown improvements in isokinetic strength, power production and mobility of youth with CP. However, no studies have assessed whether these clinically relevant improvements are linked with changes in the sensorimotor cortical oscillations. The objective of this study was to utilize MEG …

Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson

Theses & Dissertations

Multiple cancer populations frequently report cognitive impairment following treatment with chemotherapy agents (“chemo-brain”). Impaired neuropsychological performance is commonly reported in cognitive domains of attention and executive function. Understanding neural mechanisms underlying cognitive impairments is essential to developing prevention and rehabilitation strategies. Brain imaging studies frequently show chemotherapy-related impairments within the attentional control network, which is comprised of a constellation of cortical regions that govern reportedly impaired cognitive functions. In the current dissertation research, I developed a novel electrophysiology battery aimed at recording near-instantaneous neural activity within the attentional control network during cognitive task performance. Cancer patients diagnosed with hematological malignancy …

The Role Of Glutaminase And Extracellular Vesicles In Macrophages And Microglia, Beiqing Wu

Theses & Dissertations

Glutamate serves as a crucial excitatory neurotransmitter that is essential for the proper functioning of the brain. However, excess levels of glutamate are neurotoxic and contribute to the pathogenesis of various neurodegenerative diseases, inducing HIV-1 associated neurocognitive disorders (HAND). Glutaminase 1 (GLS1) is an important mitochondrial enzyme responsible for producing glutamate from glutamine. GLS1 is upregulated during HAND and released from mitochondria to cytosol and extracellular space. However, why and how GLS1 is released remains unknown. In chapter II, we demonstrated that extracellular vesicles (EVs) carry GLS1 as cargos from cytosol to extracellular space during HIV infection and innate immune …
