Characterizing The Function Of B Cells That Accumulate In The Inflamed Central Nervous System In Anti-Myelin Autoimmunity, Lika Chowdhury

Electronic Thesis and Dissertation Repository

While the role of autoimmune T cells has been extensively studied in anti-myelin

autoimmunity, little is known about the function of B cells in multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system (CNS). B cells form clusters with T cells in the meninges directly adjacent to demyelinating lesions. Previous studies have shown that disease progression is dependent on the depletion of specific populations of B cells, but it is not clear which contributes to pathology or how. The purpose of this thesis is to characterize the population of meningeal B cells to determine how they differ …

How To Manage The Initiation Of Apomorphine Therapy Without Antiemetic Pretreatment: A Review Of The Literature, Stuart H. Isaacson, Richard B. Dewey, Rajesh Pahwa, Daniel E. Kremens

Department of Neurology Faculty Papers

Introduction

Pretreatment with the antiemetic trimethobenzamide has been recommended practice in the United States (US) to address the risk of nausea and vomiting during initiation of apomorphine treatment. However, trimethobenzamide is no longer being manufactured in the US, and despite the recent update to the US prescribing information, there may be uncertainty regarding how to initiate apomorphine.

Methods

To better understand why antiemetic pretreatment was recommended and if it is necessary when initiating apomorphine therapy, we performed a literature review of subcutaneous apomorphine therapy initiation with and without antiemetic pretreatment in patients with PD.

Results

Three studies were identified as …

Med12 Is A Critical Regulator Of Neural Crest Lineage And Nervous System Myelination, Fatma Betul Aksoy Yasar

Dissertations & Theses (Open Access)

The Mediator complex (MED) is a multi-subunit protein complex integral to the eukaryotic transcription machinery. MED12 is a Cdk8- regulatory kinase module subunit directly implicated in human disease and is genetically altered in neurological disease and cancer. Numerous attempts at generating an in vivo system to study the role of Med12 failed due to embryonic lethality associated with germline or developmental disruption of Med12 gene. To understand the cellular and molecular processes associated with its role in disease, we generated multiple mouse models with targeted depletion of MED12 in distinct cellular lineages. Our genetically engineered models with induced and conditional …

The Uncertainty And Psychological Health Of Family Caregivers Of Patients With Delirium In Intensive Care Units, Amal Shokri Haji Assa

Theses and Dissertations (ETD)

Each year, more than 5 million patients are admitted to an intensive care unit (ICU) in the United States, and up to 80 % of these patients develop delirium. Delirium is a common indicator of acute brain dysfunction in the ICU and a predictor of mortality, longer ICU/hospital stay, and long-term cognitive impairment. Family caregivers are a valuable resource in preventing, detecting, and managing delirium in the ICU. However, witnessing delirium episodes can generate adverse psychological symptoms in family caregivers that may compromise their health and well-being. Research in this area has demonstrated a gap in the literature regarding how …

Defining The Impact Of Clinically Modeled Hindlimb Stretching, Exercise, & Inactivity On Functional Recovery After Spinal Cord Injury., Greta Cesarz

Electronic Theses and Dissertations

Spinal cord injury (SCI) is a devastating, life altering event that affects approximately 282,000 Americans. The most obvious side effect of SCI is paralysis due to damage to the spinal cord that disrupts ascending and descending pathways as well as central pattern generating circuitry. In addition to paralysis, patients suffer from other debilitating side effects including altered cardiovascular function, autonomic dysreflexia, neuropathic pain, spasticity, and contractures. In contrast to humans, rodents display spontaneous locomotor recovery following incomplete SCI due to in-cage activity/training. Previously, our laboratory has studied the effect of lack of in-cage training by utilizing custom designed rodent wheelchairs. …

Identifying Voice-Based Digital Biomarkers Of Parkinson's Disease, Rachelle Beshay, Madison Gill, Michael Shiraishi, Rahul Soangra

Student Scholar Symposium Abstracts and Posters

Introduction: Parkinson's disease is a disorder in the central nervous system that causes tremors, abnormal gait and balance, and muscle rigidity due to loss of function in parts of the brain. Traditionally, Parkinson's is identified by the physical symptoms seen in a patient's gait and motor skills, but irregular speech patterns (hypokinetic dysarthria) is one of the first symptoms to be derived from the disease. Objective: The goal of this ongoing study is to use Mel Frequency Centrum Coefficients (MFCC), to diagnose Parkinson's in the early stages by identifying hypokinetic dysarthria. MFCC's process speech recognition patterns and produce …

Understanding Parkinson’S Disease Through Gait Initiation And Center Of Pressure, Mira Ananthanarayanan, Kiara Salceda, Michael Shiraishi, Rahul Soangra

Student Scholar Symposium Abstracts and Posters

Parkinson's disease is a neurological disorder that causes tremors and freezing of gait in diagnosed patients. Freezing of gait can be difficult to identify and intervene without laboratory based instruments data collection. Force plates have been proven to show viable results in identifying gait events such as heel contact and toe off. The complete gait cycle consists of a right-heel strike, right heel-to-toe shift, simultaneous right-toe off/left heel strike, left heel-to-toe shift, and a simultaneous left-toe off/right heel strike. This study will investigate center of pressure trajectories when initiating gait between healthy and Parkinson's participants. It is predicted that the …

Effects Of Transcranial Direct Current Stimulation On Adults With Post-Acute Covid-19 Syndrome, Isaac Min, Aaron Schurger

Student Scholar Symposium Abstracts and Posters

Since its detection in December 2019, coronavirus disease 2019 (COVID-19), the viral disease caused by the SARS-CoV-2 novel coronavirus, has had prominent effects on human health and mortality. Studies in previous infections of SARS-CoV and MERS-CoV have found evidence of persistent symptoms in recovered patients, such as lethargy and shortness of breath. Similar residual symptoms have also been seen in recovered COVID-19 patients beyond four weeks of the initial onset of symptoms — collectively termed post-acute COVID-19 syndrome (PACS). These symptoms include deficits in working memory. Preliminary studies done in the United States and Europe have shown a significant portion …

Delta Oscillation Coupled Propagating Fast Ripples Precede Epileptiform Discharges In Patients With Focal Epilepsy, Shennan A. Weiss, Laurent Sheybani, Nitish Seenarine, Itzhak Fried, Chengyuan Wu, Ashwini Sharan, Jerome Engel Jr., Michael R. Sperling, Yuval Nir, Richard J. Staba

Department of Neurology Faculty Papers

Epileptiform spikes are used to localize epileptogenic brain tissue. The mechanisms that spontaneously trigger epileptiform discharges are not yet elucidated. Pathological fast ripple (FR, 200–600 Hz) are biomarkers of epileptogenic brain, and we postulated that FR network interactions are involved in generating epileptiform spikes. Using macroelectrode stereo intracranial EEG (iEEG) recordings from a cohort of 46 patients we found that, in the seizure onset zone (SOZ), propagating FR were more often followed by an epileptiform spike, as compared with non-propagating FR (p < 0.05). Propagating FR had a distinct frequency and larger power (p < 1e-10) and were more strongly phase coupled to the peak of iEEG delta oscillation, which likely correspond with the DOWN states during non-REM sleep (p < 1e-8), than non-propagating FR. While FR propagation was rare, all FR occurred with the highest probability within +/− 400 msec of epileptiform spikes with superimposed high-frequency oscillations (p < 0.05). Thus, a sub-population of epileptiform spikes in the SOZ, are preceded by propagating FR that are coordinated by the DOWN state during non-REM sleep.

BACKGROUND: A third of people with juvenile myoclonic epilepsy (JME) are drug-resistant. Three-quarters have a seizure relapse when attempting to withdraw anti-seizure medication (ASM) after achieving seizure-freedom. It is currently impossible to predict who is likely to become drug-resistant and safely withdraw treatment. We aimed to identify predictors of drug resistance and seizure recurrence to allow for individualised prediction of treatment outcomes in people with JME.

METHODS: We performed an individual participant data (IPD) meta-analysis based on a systematic search in EMBASE and PubMed - last updated on March 11, 2021 - including prospective and retrospective observational studies reporting on …

Living With Multiple Sclerosis As A Former Marathon Runner: Impact Of Attitude And Past Behaviour On Self-Care Maintenance And Perseverance, Michael Stephanou

Patient Experience Journal

As healthcare professionals, we have a duty to promote the wellbeing of individuals living with chronic diseases and this could be accomplished through the establishment of self-care strategies that are both collaborative and self-directed. Insight into the complex behaviours and backgrounds of individuals who show initiative in dealing with chronic disease could help achieve this by revealing drivers of health-seeking and engaging behaviours. Therefore, by deducing the complex interactions between attitude, past experiences and disease outlook, broader patient welfare could be championed through the implementation of targeted interventions which promote self-care in chronic disease. This article aims to explore these …

Living With Brain Cancer: From Researcher To Patient, Stephen P. Chelko, Daniel L. Fay Ph.D.

Patient Experience Journal

As an academic researcher, my work-life revolves around testing the efficaciousness of pharmaceutical drugs on the prevention of cardiac dysfunction, arrhythmias, and sudden cardiac death in animal models of heart disease. I never thought I would go from someone studying a life-threatening disease to a patient living with one in twenty-four hours. Yet, that transformation occurred October 8, 2019. I was just appointed to Assistant Professor at Johns Hopkins University School of Medicine (JHUSOM), yet after sitting for my professional headshot I had a grand mal seizure. I cannot recall this event, but I bit the tip of my tongue …

What Do We Know So Far About Ofatumumab For Relapsing Multiple Sclerosis? A Meta-Analytical Study, Hafiza Munazza Taj, Maryam Talib, Sania Siddiqa, Azza Sarfraz, Zouina Sarfraz, Karla Robles-Velasco, Ivan Cherrez-Ojeda

Department of Paediatrics and Child Health

Ofatumumab is a monoclonal antibody that reduces the level of B cells that alter the progression of relapsing multiple sclerosis. Originally approved by the Food and Drug Administration (FDA) in August 2020, this meta-analysis determines the outcomes of four randomized controlled trials (RCTs) for endline outcomes of Gadolinium-enhancing T1 lesions on MRI scans reported as Cohen's d and relapse rate reported as risk ratio. All four RCTs reported favorable findings of gadolinium-enhancing T1 lesions (Cohen's d = -0.44, p < 0.00001). The relapse rate was reduced by 46% post ofatumumab administration (RR = 0.54, p < 0.00001). With 14 ongoing trials in this area, more data is required to consolidate our findings.

Spontaneous Pneumothorax: A Rare Complication Of Neurofibromatosis Type 1 Associated Diffuse Lung Disease, Emma I. Sherfinski, Mark H. Cooper Md, Phd

Marshall Journal of Medicine

The visually striking neurocutaneous findings of neurofibromatosis type 1 (NF1) are well recognized and have been well documented throughout scientific literature. While not uncommon, the pulmonary manifestations of NF1 are unknown to many physicians. Complications of NF1 associated diffuse lung disease (NF-DLD) include pulmonary hypertension, pulmonary artery stenosis, subpleural cysts, and spontaneous pneumothorax. We present a case of a 34-year-old male with NF-DLD found incidentally in adolescence with previous apical bleb repair, presenting nearly twenty years later with spontaneous pneumothorax. In NF1 patients with pulmonary complaints, NF-DLD should be assessed with computed tomography (CT) and physicians should be familiar with …

Efficacy And Safety Of A Brain-Penetrant Biologic Tnf-Α Inhibitor In Aged App/Ps1 Mice, Weijun Ou, Yuu Ohno, Joshua Yang, Devaraj V. Chandrashekar, Tamara Abdullah, Jiahong Sun, Riley Murphy, Chuli Roules, Nataraj Jagadeesan, David H. Cribbs, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Tumor necrosis factor alpha (TNF-α) plays a vital role in Alzheimer’s disease (AD) pathology, and TNF-α inhibitors (TNFIs) modulate AD pathology. We fused the TNF-α receptor (TNFR), a biologic TNFI that sequesters TNF-α, to a transferrin receptor antibody (TfRMAb) to deliver the TNFI into the brain across the blood–brain barrier (BBB). TfRMAb-TNFR was protective in 6-month-old transgenic APP/PS1 mice in our previous work. However, the effects and safety following delayed chronic TfRMAb-TNFR treatment are unknown. Herein, we initiated the treatment when the male APP/PS1 mice were 10.7 months old (delayed treatment). Mice were injected intraperitoneally with saline, TfRMAb-TNFR, etanercept (non-BBB-penetrating …

Research outputs 2022 to 2026

Cholesterol levels have been repeatedly linked to Alzheimer's Disease (AD), suggesting that high levels could be detrimental, but this effect is likely attributed to Low-Density Lipoprotein (LDL) cholesterol. On the other hand, High-Density Lipoproteins (HDL) cholesterol levels have been associated with reduced brain amyloidosis and improved cognitive function. However, recent findings have suggested that HDL-functionality, which depends upon the HDL-cargo proteins associated with HDL, rather than HDL levels, appears to be the key factor, suggesting a quality over quantity status. In this report, we have assessed the HDL-cargo (Cholesterol, ApoA-I, ApoA-II, ApoC-I, ApoC-III, ApoD, ApoE, ApoH, ApoJ, CRP, and SAA) …

Heavy alcohol consumption is a known risk factor for various forms of dementia and the development of Alzheimer’s disease (AD). In this work, we investigated how intragastric alcohol feeding may alter the liver-to-brain axis to induce and/or promote AD pathology. Four weeks of intragastric alcohol feeding to mice, which causes significant fatty liver (steatosis) and liver injury, caused no changes in AD pathology markers in the brain [amyloid precursor protein (APP), presenilin], except for a decrease in microglial cell number in the cortex of the brain. Interestingly, the decline in microglial numbers correlated with serum alanine transaminase (ALT) levels, suggesting …

Comprehensive Care To Improve Quality Of Life: A Case Of Childhood Adrenoleukodystrophy, Miraal S. Dharamsi, Adrian A. Mejia, Cecilia De Vargas

HCA Healthcare Journal of Medicine

The childhood cerebral form of adrenoleukodystrophy (ALD) causes rapid demyelination of cerebral white matter and is clinically characterized by hyperactivity, emotional changes, and poor school performance, as well as progressive cognitive, visual, auditory, speech, and motor decline. While aggressive behavior is a known complication of ALD, treatment of the disease is limited. Moreover, behavioral management is not well described in the available literature, particularly from a psychiatric standpoint. In this case presentation, the patient’s parents reported significant agitation and aggression, which may have been secondary to verbal deficits, in addition to the general neuropathological implications of this disease. Although this …

Development Of Graphical Models And Statistical Physics Motivated Approaches To Genomic Investigations, Yashwanth Lagisetty

Dissertations & Theses (Open Access)

Identifying genes involved in disease pathology has been a goal of genomic research since the early days of the field. However, as technology improves and the body of research grows, we are faced with more questions than answers. Among these is the pressing matter of our incomplete understanding of the genetic underpinnings of complex diseases. Many hypotheses offer explanations as to why direct and independent analyses of variants, as done in genome-wide association studies (GWAS), may not fully elucidate disease genetics. These range from pointing out flaws in statistical testing to invoking the complex dynamics of epigenetic processes. In the …

Multicomponent Approach To Delirium Prevention In The Acute Care Setting: An Evidence-Based Quality Improvement Project., Kelley James

Doctor of Nursing Practice Papers

Background: Acutely ill, hospitalized individuals are at an increased likelihood of developing delirium. Between 30-35% of those patients admitted to the hospital will develop delirium, and as a result, these individuals will face an increased risk of mortality, adverse medical events, restraint usage, and incur a more extended hospitalization. The literature supports early screening utilizing the Confusion Assessment Method (CAM) tool and nurse-driven, multicomponent interventions to aid in preventing its development.

Environment: This project was implemented in a long-term, acute care facility specializing in patients requiring long-term mechanical ventilation, advanced wound care, pulmonary and respiratory care, and the rehabilitation of …

Myasthenia Gravis, Rebecca Wheeler

Nursing Student Class Projects (Formerly MSN)

Myasthenia gravis (MG), a neuromuscular and autoimmune disorder, is not completely understood by clinicians and scientists. The primary cause is thought to be anti-Acetylcholine receptor antibodies that attack the neuromuscular junction, causing destruction of post-synaptic junctional folds and blockade of the receptor. This causes frequent weakness and fatigability of voluntary muscles, making activities of daily living difficult for those living with MG. Although it is not an incredibly prevalent disease, the incidence is increasing in the United States due to better testing and diagnosis. Treatments are available, including cholinesterase inhibitors that raise the concentration of Acetylcholine at the neuromuscular junction …

Crel And Wnt5a/Frizzled 5 Receptor-Mediated Inflammatory Regulation Reveal Novel Neuroprotectin D1 Targets For Neuroprotection, Jorgelina M. Calandria, Khanh V. Do, Sayantani Kala-Bhattacharjee, Andre Obenaus, Ludmila Belayev, Nicolas G. Bazan

School of Medicine Faculty Publications

Abstract: Wnt5a triggers inflammatory responses and damage via NFkB/p65 in retinal pigment epithelial (RPE) cells undergoing uncompensated oxidative stress (UOS) and in experimental ischemic stroke. We found that Wnt5a-Clathrin-mediated uptake leads to NFkB/p65 activation and that Wnt5a is secreted in an exosome-independent fashion. We uncovered that docosahexaenoic acid (DHA) and its derivative, Neuroprotectin D1 (NPD1), upregulate c-Rel expression that, as a result, blunts Wnt5a abundance by competing with NFkB/p65 on the Wnt5a promoter A. Wnt5a increases in ischemic stroke penumbra and blood, while DHA reduces Wnt5a abundance with concomitant neuroprotection. Peptide inhibitor of Wnt5a binding, Box5, is also neuroprotective. DHA-decreased …
