Surgical Resection Of Convexity Meningiomas: A Single Center Retrospective Analysis, Haley Wendt, Michael Baldassari, Donald Ye, Kevin Judy

Phase 1

Introduction: Dural convexity meningiomas (CMs) are the most common primary intracranial tumors. Although surgical resection carries relatively low risk, it is necessary to quantify perioperative risks from a large patient cohort and identify factors contributing to short-term and long-term outcomes.

Methods: Patients who underwent craniotomy for resection of CMs between January 2012-December 2018 at a single large academic center were reviewed for pre-operative demographics, radiographic characteristics, and post-operative outcomes.

Results: 122 cases of CMs were identified. Common presenting symptoms included headache (39.3%), seizure (27.0%) and weakness/paralysis (18%). CMs were located over frontal, parietal, temporal, and occipital lobes in 57.4%, …

A Closer Look At The Psychiatric Effects Of Deep Brain Stimulation To Further Guide Treatment Of Refractory Epilepsy: A Focused Review, Latangela Smith

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

Introduction: Effective treatment of medically-refractory epilepsy remains a formidable challenge in many patients. The SANTE trial (2010) led to the FDA approval of deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) for the treatment of medically-refractory epilepsy. However, ANT DBS also raised significant mental health concerns. This review will take another look at the psychiatric effects of DBS to more definitively outline the mental health risks and identify additional targets to guide future treatment.

Methods: A search of the clinical literature published between January 1, 1990 and December 31, 2019 was completed. The most relevant papers …

Blalock, Sumedha Gunewardena, Steven M. Shapiro, Sean M. Riordan, Peter Huettl, Zain Guduru, John A. Stanford, Craig G. Van Horne, Greg A. Gerhardt

Neuroscience Faculty Publications

The development of regenerative therapies for central nervous system diseases can likely benefit from an understanding of the peripheral nervous system repair process, particularly in identifying potential gene pathways involved in human nerve repair. This study employed RNA sequencing (RNA-seq) technology to analyze the whole transcriptome profile of the human peripheral nerve in response to an injury. The distal sural nerve was exposed, completely transected, and a 1 to 2 cm section of nerve fascicles was collected for RNA-seq from six participants with Parkinson's disease, ranging in age between 53 and 70 yr. Two weeks after the initial injury, another …

2020 Symposium Posters

Introduction

Neurologic insults such as strokes and traumatic brain injuries (TBI) affect over 1 million Americans every year. The lack of current knowledge informing accurate prognoses causes victims and their loved ones distress, and is a focus of much research. The purpose of this study was to determine whether patient age at time of insult could predict change in functional outcomes during inpatient rehabilitation.

Methods

Subjects were patients of an inpatient rehabilitation facility (IRF) post-stroke or TBI. The Functional Independence Measure (FIM) assessed functional independence and cognitive status at admission and discharge from the IRF. The Montebello Rehabilitation Factor Score …

Effect Of Sleep Deprivation And Sleep Recovery On Heart Rate And Heart Rate Variability In Males Versus Females, Abrianna Lochner Spt, Elena Crooks Pt, Dpt, Phd, Myles Gordon Finlay Ba, Julie A. Erwin Ms, Kimberly Honn Phd

2020 Symposium Posters

Introduction

Elevated heart rate (HR) and low HR variability (HRV) are indicators of increased sympathetic tone and cardiovascular risk. Here, we assess the effect of one night of sleep deprivation and a subsequent night of recovery sleep on HR and HRV in healthy males versus females.

Methods

Fifty-nine subjects (29.5±8.5y, n=35 female) completed a 4-day/3-night laboratory study. Subjects had a baseline sleep opportunity (22:00–08:00), followed by 38h of sleep deprivation, and a recovery sleep opportunity (22:00–08:00). EKG was monitored via Holter monitors to measure HR and the pNN50 and rMMSD variables of HRV. Time points used for analyses included 09:00–09:20 …

Rescue Stenting For Failed Mechanical Thrombectomy Procedures, Joseph Schaefer, Ahmad Sweid, Md, M. Reid Gooch, Md, Pascal Jabbour, Md

Phase 1

Background: Mechanical thrombectomy (MT) has dramatically changed the natural history of acute ischemic stroke. The disease that was associated with high morbidity, mortality, and significant cost on the health care system became a treatable disease. One of the most important variables to improve outcomes is time to revascularize the ischemic tissue. Rescue stenting (RS) is an option for patients who fail MT.

Methods: A retrospective chart review for patients who underwent a MT procedure and either failed (defined as TICI 0-2a) or required a RS from 2015 – 2019 composed the study population. IRB approval was obtained and the consent …

Clinical And Neurophysiological Effects Of Dry Needling On Individuals With Chronic Ankle Instability, Jennifer Mullins

Theses and Dissertations--Rehabilitation Sciences

Ankle sprains are generally considered innocuous injuries; however, as many as 74% of patients will develop chronic symptoms. 1-3 Chronic ankle instability (CAI) is defined by a history of ankle sprain accompanied by ongoing bouts of giving way, residual ankle sprain symptoms, and a decrease in patient-perceived function. As understanding of sensorimotor deficits in individuals with CAI have advanced, treatment strategies have evolved to include a robust focus on balance training to mitigate dynamic and static postural control impairments exhibited in individuals with CAI. A problem arises as these improvements have not been conclusively linked to a decrease in CAI. …

Cerebrospinal Fluid Neurofilament Light Concentration Predicts Brain Atrophy And Cognition In Alzheimer's Disease, Kunal Dhiman, Veer Bala Gupta, Victor L. Villemagne, Dhamidhu Eratne, Petra L. Graham, Christopher Fowler, Pierrick Bourgeat, Qiao-Xin Li, Steven Collins, Ashley I. Bush, Christopher C. Rowe, Colin L. Masters, David Ames, Eugene Hone, Kaj Blennow, Henrik Zetterberg, Ralph N. Martins

Research outputs 2014 to 2021

Introduction
This study assessed the utility of cerebrospinal fluid (CSF) neurofilament light (NfL) in Alzheimer's disease (AD) diagnosis, its association with amyloid and tau pathology, as well as its potential to predict brain atrophy, cognition, and amyloid accumulation.
Methods
CSF NfL concentration was measured in 221 participants from the Australian Imaging, Biomarkers & Lifestyle Flagship Study of Ageing (AIBL).
Results
CSF NfL levels as well as NfL/amyloid β (Aβ42) were significantly elevated in AD compared to healthy controls (HC; P < .001), and in mild cognitive impairment (MCI) compared to HC (P = .008 NfL; P< .001 NfL/Aβ42). CSF NfL and NfL/Aβ42 differentiated AD from HC with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.84 and 0.90, respectively. CSF NfL and NfL/Aβ42 predicted cortical amyloid load, brain atrophy, and cognition.
Discussion
CSF NfL is a biomarker of neurodegeneration, correlating with cognitive impairment and brain neuropathology.

Test–Retest Reliability Of The Friedreich’S Ataxia Rating Scale, Christian Rummey, Theresa A. Zesiewicz, Santiago Perez-Lloret, Jennifer M. Farmer, Massimo Pandolfo, David R. Lynch

Neurology Faculty Publications

The modified Friedreich Ataxia Rating Scale (mFARS) is a disease specific, exam-based neurological rating scale commonly used as a outcome measure in clinical trials. While extensive clinimetric testing indicates it’s validity in measuring disease progression, formal test–retest reliability was lacking. To fill this gap, we acquired results from screening and baseline visits of several large clinical trials and calculated intraclass correlation coefficients, coefficients of variance, standard error, and the minimally detectable changes. This study demonstrated excellent test–retest reliability of the mFARS, and it’s upright stability subscore.

Untreated Stroke As Collateral Damage Of Covid-19: “Time Is Brain” Versus “Stay At Home, David Z. Rose, W. Scott Burgin, Swetha Renati

Neurology Faculty Publications

For decades, neurologists have been advocating that anyone with acute focal deficits report immediately to the closest hospital’s emergency room. Major advancements in the hyperacute diagnosis and treatment of stroke have justified our call-to-action slogan of “Time is Brain”—faster therapy leads to superior outcomes. However, this mantra has been recently usurped by the catchphrase “Stay at Home” during the coronavirus disease 2019 (COVID-19) pandemic. Fewer patients are presenting to hospitals with acute stroke; our census is down. Presumably the etiology of this phenomenon is either strict “social distancing” that some people may misperceive to exclude even emergent situations, or fears …

Fusiform Superior Cerebellar Artery Aneurysm Treated With Flow Diversion: A Case Report, Y. Serulle, D. Khatri, J. Fletcher, A. Pappas, A. Heidbreder, D. Langer, R. A. Ortiz

Journal Articles

© 2020 Published by Scientific Scholar on behalf of Surgical Neurology International. Background: Fusiform aneurysms of the distal superior cerebellar artery are rare and challenging to treat. Due to the rarity of these lesions, there is little consensus regarding their management. Treatment options have traditionally included parent artery sacrifice with either an endovascular approach or microsurgical clipping. Given the small diameter of the superior cerebellar artery, flow diversion has not been typically considered as a viable treatment option for these aneurysms. Case Description: A 67-year-old female presented complaining of severe sudden onset headache. Noncontrast head CT demonstrated no intracranial hemorrhage. …

Tdp-43 Is Elevated In Plasma Neuronal-Derived Exosomes Of Patients With Alzheimer’S Disease, N. Zhang, D. Gu, M. Meng, M. L. Gordon

Journal Articles

© Copyright © 2020 Zhang, Gu, Meng and Gordon. Background: Recently, TDP-43 has been recognized as a common proteinopathy in the “oldest old” and a neuropathological comorbidity in patients with Alzheimer’s disease (AD). However, since it has a low concentration in cerebrospinal fluid, the presence of TDP-43 in AD is rarely investigated in vivo. Methods: Twenty-four patients with amyloid PET confirmed AD and 15 healthy controls (HCs) were included in this study. TDP-43 level in plasma neuronal-derived exosomes (NDEs) was measured by enzyme-linked immunosorbent assay. Results: TDP-43 level was elevated in patients with AD compared with HCs (median 1.08 ng/ml, …
