Improving Door-To-Groin Time For Stroke-Alert Patients Arriving At Tjuh, Megan Carney, Mackenzie O'Connor, Robin Dharia, Md

Phase 1

Introduction: Due to the large number of endovascular-eligible acute ischemic stroke patients, the urgent nature of effective stroke treatment protocols has become increasingly recognized at TJUH. Due to the hospital’s unique situation with two city blocks between the ER and endovascular lab, in-hospital factors remain a significant reason for the delay of treatment.

Objective: The purpose was to conduct a quality-assurance trial to determine whether standardizing imaging modalities for inpatient and ER stroke-alert patients at our institution would improve door-to-puncture times.

Methods: After implementation of the new stroke alert protocol, data were prospectively collected for six months for two groups …

Network Influence Of The Cerebellum For Predicting Dbs Response In Patients With Advanced Parkinson’S Disease, Lucy Li, Jennifer Muller, Sara Thalheimer, Mackenzie D. Silverman, Mahdi Alizadeh, Tsao-Wei Liang, Kelly Layton, Daniel Kremens, Victor Romo, Feroze Mohamed, Chengyuan Wu

Phase 1

Introduction: Deep brain stimulation (DBS) is a treatment option for reducing motor symptoms in patients with Parkinson’s Disease (PD) when first-line medication becomes ineffective. Existing literature has hypothesized that the clinical outcome of DBS may depend on brain connectivity profiles of the stimulation site to distant brain regions. However, the potential of brain connectivity profiles to predict response to DBS in PD remains unclear.

Objective: This study aimed to investigate how changes in structural and functional connectivity may relate to patient response to DBS, through the examination of brain network changes using graph theory.

Methods: Ten patients with advanced PD …

Impact Of Early Mobilization On 90-Day Outcomes In Thrombectomy Patients, Tamela Stuchiner, Diane Clark, Lindsay Lucas, John Robinson, Lisa Yanase

Books, Presentations, Posters, Etc.

Introduction: Early mobilization of ischemic stroke patients receiving IV alteplase (tPA) did not worsen 90-day outcome at two urban stroke centers in a prior study, but there are no studies evaluating outcomes of early mobilization after thrombectomy. The mobility protocol used in the previous study was also utilized to mobilize stroke patients receiving thrombectomy treatment at these two centers, once minimum number of hours for groin precautions was complete and the groin puncture site was stable. The objective of this study was to determine for post-thrombectomy patients mobilized within 24 hours, whether earlier mobilization worsened outcomes.

Methods: Medical records of …

Standardized Code Stroke Inpatient Activation Process Resulted In Consistent Acute Stroke Evaluation Times Regardless Of Primary Problem Or Patient Location, Kailey Cox, Brandon Sheets, Alyx Lesko, Lindsay Lucas, Elizabeth Baraban, Ronda Chandler, Diane Clark

Books, Presentations, Posters, Etc.

Introduction: Inpatient strokes have a higher mortality risk and longer length of stay compared to community-onset strokes. The inpatient stroke population is often not included in national registries. This study examines a hospital-wide standardized process for acute triage of Code Stroke Inpatient Activations (CSIAs) at a Comprehensive Stroke Center.

Methods: CSIA data collected between September 2016-July 2018 from the Stroke and Rapid Response Team pager were used. False CSIAs were excluded. Outcomes included percentage of CSIAs by patient location (PL), primary problem (PP), and final discharge diagnosis (FDD), as well as percentage treated with IV-alteplase (tPA) and thrombectomy. Evaluation times …

Increase In Video Evaluations But Not Complications Over Time In A Large Stroke Network, Archit Bhatt, Elizabeth Baraban, Leslie Corless, Lindsay Lucas

Books, Presentations, Posters, Etc.

Introduction: Telestroke technology allows evaluation of stroke patients remotely. We sought to determine if there was any change in the standard of care and evaluation of stroke patients over time and whether there were differences in complication rates between those who were evaluated using telestroke technology and those who were not.

Methods: Data from April 2010 to May 2018 from a large stroke network were used. Acute ischemic stroke patients who presented to the emergency departments (ED) with last-known-well-to-door less than 4.5 hours and were treated with IV-alteplase were included. The number of facilities ranged from 7 in 2010 to …

Implementation Of Coordinated Telestroke Program In An Urban Setting Improves Acute Stroke Care, John Zurasky, Leslie Corless, Lindsay Lucas, Elizabeth Baraban

Books, Presentations, Posters, Etc.

Purpose: Telestroke has been shown to improve acute ischemic stroke (AIS) care in rural settings, but few studies have examined the impact of telestroke in an urban setting. In an urban area, there was a planned transition from an outpatient-based acute stroke provider pool to a centralized telehealth team of neurovascular and neurocritical care providers. This study assessed the impact of this change by comparing patient outcomes during three time periods: pre-initiation (PRE), transition after initiation (TRAN) and post-transition (POST).

Methods: Data for AIS patients 18 and older from five urban hospitals were used. Outcomes were hospital length of stay …

A Propensity-Matched Analysis Of Outcomes For Patients With M2 Branch Occlusions At Endovascular Stroke Centers, R. Ovando, L. Lucas, Elizabeth Baraban, Jason Tarpley

Articles, Abstracts, and Reports

Introduction: Endovascular therapy (EVT) for Emergent Large Vessel Occlusion (ELVO) is recommended for patients with acute proximal MCA (M1 segment) occlusions (Class I, level A evidence), but the benefits of EVT are uncertain in patients with M2 and more distal occlusions. The purpose of this study was to compare the efficacy and outcomes of EVT-treated M2 ELVOs with EVT-treated M1 ELVOs, and to examine the outcomes of EVT-treated M2 ELVO patients with those whose M2 ELVOs were not treated.

Methods: Data were obtained from a multi-hospital system of patients from January 2014 and May 2018. Two propensity score (PS)-based nearest-neighbor …

Contact Sports As A Risk Factor For Amyotrophic Lateral Sclerosis: A Systematic Review., Ronen Blecher, Michael A Elliott, Emre Yilmaz, Joseph R Dettori, Rod J Oskouian, Akil P Patel, Andrew Clarke, Mike Hutton, Robert Mcguire, Robert Dunn, John Devine, Bruce Twaddle, Jens R Chapman

Articles, Abstracts, and Reports

Study Design: Systematic review.

Introduction: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, ultimately resulting in paralysis and death. The condition is considered to be caused by a complex interaction between environmental and genetic factors. Although vast genetic research has deciphered many of the molecular factors in ALS pathogenesis, the environmental factors have remained largely unknown. Recent evidence suggests that participation in certain types of sporting activities are associated with increased risk for ALS.

Objective: To test the hypothesis that competitive sports at the highest level that involve repetitive concussive head and cervical spinal trauma result in an increased …

The Insula And Its Epilepsies, Barbara C. Jobst, Jorge Gonzalez-Martinez, Jean Isnard, Philippe Kahane, Nuria Lacuey, Samden D. Lahtoo, Dang K. Nguyen, Chengyuan Wu, Fred Lado

Department of Neurosurgery Faculty Papers

Insular seizures are great mimickers of seizures originating elsewhere in the brain. The insula is a highly connected brain structure. Seizures may only become clinically evident after ictal activity propagates out of the insula with semiology that reflects the propagation pattern. Insular seizures with perisylvian spread, for example, manifest first as throat constriction, followed next by perioral and hemisensory symptoms, and then by unilateral motor symptoms. On the other hand, insular seizures may spread instead to the temporal and frontal lobes and present like seizures originating from these regions. Due to the location of the insula deep in the brain, …

The Influence Of Unpredictable, Fragmented Parental Signals On The Developing Brain, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Mental illnesses originate early in life, governed by environmental and genetic factors. Because parents are a dominant source of signals to the developing child, parental signals - beginning with maternal signals in utero - are primary contributors to children’s mental health. Existing literature on maternal signals has focused almost exclusively on their quality and valence (e.g. maternal depression, sensitivity). Here we identify a novel dimension of maternal signals: their patterns and especially their predictability/unpredictability, as an important determinant of children’s neurodevelopment. We find that unpredictable maternal mood and behavior presage risk for child and adolescent psychopathology. In experimental models, fragmented/unpredictable …

Bilateral Acute Ocular Ischemic Syndrome Following Head And Neck Radiation, Dipali Nemade, Paul Ferguson, Vikram Shivkumar, Dennis Cole

Marshall Journal of Medicine

Previous literature has established a clear correlation between radiation therapy (RT) to the head and neck leading to aggressive atherosclerosis of the carotid arteries and subsequent increased risk for ischemic stroke. Stenosis of carotid arteries can lead to Ocular Ischemic syndrome (OIS). We present a case of acute bilateral OIS following head and neck RT for left tonsillar squamous cell carcinoma (SCC) in a 64 year-old Caucasian male. Routine large vessel cerebrovascular screening following head and neck radiotherapy should be considered as a means of potentially mitigating future stroke risk through initiation of medical therapy and interventional modalities as a …

Transdisciplinarity At The Boundaries: Exploring A Sylvan Metaphor For Health, Peter J. Whitehouse

Faculty Scholarship

Transdisciplinarity is an action oriented intellectual and ethical endeavor to address complex ecological, economic, and political challenges that humans face. Language is viewed as a powerful tool for necessary cultural change. Blending art and science looking for the difficult to define but critically important hidden spaces between apparently rigid conceptual structures is a core of transdisciplinarity. Metaphor is a particular powerful tool for examining boundaries and developing creative blends of structures and processes. Forests are biologically and culturally critical to life on the planet. In this paper we explore, a performance character named Sylvanus, the Tree Doctor, named after the …

Diffusion-Weighted Magnetic Resonance Imaging May Be Useful In Differentiating Fungal Abscess From Malignant Intracranial Lesion: Case Report, Syeda Maheen Batool, Fatima Mubarak, Ather Enam

Section of Neurosurgery

Background: Diffusion-weighted magnetic resonance has a well-defined role in differentiating between important intracranial lesions. Sometimes, the surgeon is faced with a dilemma of how to diagnose an infectious versus malignant lesion.
Case Description: A 28-year-old male presented to the neurosurgery clinic with complaints of headache and left-sided weakness for 2 weeks. Neurological examination was intact. Magnetic resonance imaging (MRI) scan showed a large infiltrating heterogeneous mass involving the right parietal lobe. On further reviewing, there was homogenous diffusion restriction in the center of lesion. In addition, its aggressive behavior confirmed it to be a fungal abscess.
Conclusions: Correctly identifying an …

Static And Dynamic Postural Control Deficits In Aging Fragile X Mental Retardation 1 (Fmr1) Gene Premutation Carriers., Zheng Wang, Pravin Khemani, Lauren M Schmitt, Su Lui, Matthew W Mosconi

Articles, Abstracts, and Reports

BACKGROUND: Individuals with premutation alleles of the fragile X mental retardation 1 (FMR1) gene are at risk of developing fragile X-associated tremor/ataxia syndrome (FXTAS) during aging. Characterization of motor issues associated with aging in FMR1 premutation carriers is needed to determine neurodegenerative processes and establish new biobehavioral indicators to help identify individuals at greatest risk of developing FXTAS.

METHODS: We examined postural stability in 18 premutation carriers ages 46-77 years and 14 age-matched healthy controls. Participants completed a test of static stance and two tests of dynamic postural sway on a force platform to quantify postural variability and complexity. CGG …
