Pay Attention! A Comparative Analysis Of Psychological Assessments And Neurological Mechanisms For Adhd Within A Pediatric Population, Kristen E. Newberry

Antioch University Dissertations & Theses

This study evaluated the predictiveness of the WISC-V, NEPSY-II, CPT-3, and CATA when compared to each other in a sample of 272 children aged 8–16. Archival data was analyzed using binary and multinomial logistic regression models to assess concurrent validity of specific subtests and indexes. Participants were grouped by ADHD subtype (inattentive, combined/hyperactive, or no diagnosis), with gender and executive functioning measures included in the models. Findings indicated that lower Cognitive Proficiency Index (CPI) and executive functioning scores (e.g., Animal Sorting, Response Set) predicted any ADHD diagnosis compared to the no diagnosis group, whereas higher CATA scores predicted lower Inattentive …

Alpha-Synuclein Interaction With Gedunin, Tony Matundura Nyabayo

Graduate Theses/Dissertations

Parkinson’s disease (PD) and other Proteinopathies develop when α-synuclein misfolds and aggregates into toxic amyloids. While existing treatments for PD are primarily focused on managing its symptoms, a viable solution for slowing down the progress of Parkinson’s disease involves targeting the toxic α-synuclein amyloids. Gedunin, a natural inhibitor of heat shock protein 90, has been extensively used to treat malaria. Also, recent research investigations have shed light on its potential beyond malaria therapy, indicating that Gedunin may offer a possible solution for treating a variety of neurodegenerative diseases. Using plate-based assays, we examined how Gedunin influences α-synuclein fibrillation and its …

Cross-Species Comparisons Between Pigs And Mice Reveal Conserved Sex-Specific Intraspinal Inflammatory Responses After Spinal Cord Injury, Reena Kumari, Gabrielle V. Hammers, Robert H. Hammons, Andrew N. Stewart, Steven M. Maclean, Tracy Niedzielko, Lonnie E. Schneider, Candace L. Floyd, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

Objective Therapeutic translation is challenging in spinal cord injury (SCI) and large animal models with high clinical relevance may accelerate therapeutic development. Pigs have important anatomical and physiological similarities to humans. Intraspinal inflammation mediates SCI pathophysiology. The purpose of this study was to evaluate the effect of sex on inflammation and outcomes in a pig thoracic contusion/compression SCI model.

Methods Adult (gonad-intact) male and female Yucatan miniature swine were subjected to either SCI or sham (laminectomy-only) injury.

Results SCI caused locomotor dysfunction (measured with the Porcine Thoracic Injury Behavior Score) with some recovery over 6 weeks and limited tissue sparing …

Cytosolic Phospholipase A2 In Infiltrating Monocyte Derived Macrophages Does Not Impair Recovery After Spinal Cord Injury In Female Mice, Ethan Glaser, Timothy J. Kopper, William M. Bailey, Hassan K. Kashif, Reena Kumari, Andrew N. Stewart, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

Spinal cord injury (SCI) leads to permanent motor and sensory loss that is exacerbated by intraspinal inflammation and persists months to years after injury. After SCI, monocyte-derived macrophages (MDMs) infiltrate the lesion to aid in myelin-rich debris clearance. During debris clearance, MDMs adopt a proinflammatory phenotype that exacerbates neurodegeneration and hinders recovery. The underlying cause of the lipid-mediated MDM phenotype shift is unclear. Our previous work suggests that cytosolic phospholipase A2 (cPLA2) plays a role in the proinflammatory potentiating effect of myelin on macrophages in vitro. Cytosolic phospholipase A2 (cPLA2) frees arachidonic acid from phospholipids, generating eicosanoids that play an …

Pape, Juan Fortea, Nicholas J. Ashton, Chinedu Udeh-Momoh, Sid E. O’Bryant, Dwight German, Florin Despa, Mark Mapstone, Henrik Zetterberg

Neurology Faculty Publications

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer’s Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral

Theses and Dissertations--Psychology

Substance use disorders impose a staggering toll on the United States (U.S.), straining healthcare systems, destabilizing communities, and profoundly impacting both individuals and families. Approximately one in six Americans aged 12 and older had a past-year substance use disorder in 2022 (Key Substance Use, 2022), and nearly one-third of adults experience a substance use disorder in their lifetime (Wu, 2010), contributing to an economic burden exceeding $400 billion annually (National Drug Threat Assessment, 2011). Family history of substance use disorders is a key predictor of vulnerability, with individuals who have affected relatives being 2–8 times more …

Application Of Telc Model To Better Elucidate Neural Stimulation By Touch, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

Aim: This study is to better understand how the transient ion transport activity of touch receptors could change the graded potential to stimulate an action potential firing.

Methods: The latest transmembrane-electrostatically localized protons/cations charges (TELC) theory is employed for numerical analysis to calculate the neural touch signal transduction responding time required to fire an action potential spike.

Results: A neural action potential spike was constructed successfully using newly developed time-dependent TELC-based neural transmembrane potential integral equations (Equations 5, 6, and 7). The results explicated that the TELC curve has an inverse relationship with neural transmembrane potential since its curve appears …

Electrical & Computer Engineering Faculty Publications

Background: Large bifrontal defects pose unique reconstruction challenges due to their complex curvature and mechanical requirements. This case demonstrated how computer-aided design/manufacturing (CAD/CAM) enabled precise single-piece polymethyl methacrylate (PMMA) implant fabrication, thereby overcoming traditional limitations. Case presentation: A 25-year-old male who had undergone bifrontal decompressive craniectomy suffered a severe traumatic brain injury. The autologous bone flap had been temporarily stored in a subcutaneous fat area of the abdomen for 3 months to preserve its viability. A secondary cranioplasty was then performed using titanium miniplates and self-tapping screws for final fixation. After 2 years, the patient developed empyema and a brain …

Obesity Prediction From Structural Mri Using Conformal Deep Learning With Uncertainty Quantification, W. Farzana, A. G. A. Temtam, B. Humud-Arboleda, L. Ma, M. Bean, F. Gerard Moeller, K. M. Iftekharuddin

Electrical & Computer Engineering Faculty Publications

Obesity arises from a neurobehavioral disorder in which the brain’s regulation of hunger and food intake is impaired, leading to an imbalance between energy consumption and expenditure. One key phenotype associated with obesity is body mass index (BMI). BMI is influenced by multiple causal pathways driven by behavioral, metabolic, and genetic factors. Traditional obesity prediction studies often rely on magnetic resonance imaging (MRI) voxel-based morphometry to correlate BMI with obesity-related clinical measurements and brain structure, predominantly gray matter volume (GMV). However, the altered brain regions are variable and widespread between studies, with some literature presenting contradictory results between BMI and …

Nerve injury causes neuropathic pain and multilevel nerve barrier disruption. Nerve barriers consist of perineurial, endothe- lial and myelin barriers. So far, it is unclear whether resealing nerve barriers fosters pain resolution and recovery. To this end, we analysed the nerve barrier property portfolio, pain behaviour battery and lipidomics for precursors of specialized pro-resolving meditators (SPMs) and their receptors in chronic constriction injury of the rat sciatic nerve to identify tar- gets for pain resolution by resealing the selected nerve barriers. Of the three nerve barriers—perineurium, capillaries and myelin—only capillary tightness specifically against larger molecules, such as fibrinogen, recuperated with …

Igf-1 Impacts Neocortical Interneuron Connectivity In Epileptic Spasm Generation And Resolution, Carlos J Ballester-Rosado, John T Le, Trang T Lam, Anne E Anderson, James D Frost, John W Swann

Faculty, Staff and Students Publications

Little is known about the mechanisms that generate epileptic spasms following perinatal brain injury. Recent studies have implicated reduced levels of Insulin-like Growth Factor 1 (IGF-1) in these patients' brains. Other studies have reported low levels of the inhibitory neurotransmitter, GABA. In the TTX brain injury model of epileptic spasms, we undertook experiments to evaluate the impact of IGF-1 deficiencies on neocortical interneurons and their role in spasms. Quantitative immunohistochemical analyses revealed that neocortical interneurons that express glutamic acid decarboxylase, parvalbumin, or synaptotagmin 2 co-express IGF-1. In epileptic rats, expression of these three interneuron markers were reduced in the neocortex. …

Analysis Of 1,25-Dihydroxyvitamin D Genomic Action In Human Enteroids And Colonoids Reveals Multiple Regulatory Effects Of Vitamin D In Human Intestinal Physiology, Zachary K Criss, Kali Deans-Fielder, James C Fleet, Sylvia Christakos, Noah Shroyer

Faculty, Staff and Students Publications

Introduction: The intestine has molecular and functional diversity across the proximal-distal and the crypt-villus axes, so it is imperative to determine the common and compartment-specific molecular actions of vitamin D. However, very little work on vitamin D mediated gene regulation has been done in normal human intestine. Here, we examined the impact of 1,25-dihydroxyvitamin D (1,25(OH)2D3) on cultures of human intestinal epithelium derived from duodenum (Dd) and distal colon (Co) biopsies of 6 subjects per tissue.

Methods: Human enteroids and colonoids were cultured for 3 days to promote a stem cell phenotype (undifferentiated, Un) or to induce differentiation (Diff) and …

Faculty, Staff and Students Publications

BACKGROUND: Vertebral body defects pose a significant challenge in spinal reconstructive surgery. Compression fractures of the vertebral corpus are typically treated with vertebral augmentation procedures. There are significant risks associated with the introduction of foreign material in the spine, including infection and pseudarthrosis. Vascularized bone grafts (VBGs) have become a popular alternative for spinal reconstruction in the last decade thanks to their robust blood supply and autologous nature. VBGs have been described predominantly for the reconstruction of posterior vertebral defects. The objective of this study is to describe a novel procedure for the reconstruction of vertebral corpus defects in the …

Comparative Analysis Of Aav Serotypes For Transduction Of Olfactory Sensory Neurons, Benjamin D W Belfort, Johnathan D Jia, Alexandra R Garza, Anthony M Insalaco, J P Mcginnis, Brandon T Pekarek, Joshua Ortiz-Guzman, Burak Tepe, Hu Chen, Ascent-Pd Investigators, Zhandong Liu, Benjamin R Arenkiel

Olfactory sensory neurons within the nasal epithelium detect volatile odorants and relay odor information to the central nervous system. Unlike other sensory inputs, olfactory sensory neurons interface with the external environment and project their axons directly into the central nervous system. The use of adeno-associated viruses to target these neurons has garnered interest for applications in gene therapy, probing olfactory sensory neuron biology, and modeling disease. To date, there is no consensus on the optimal AAV serotype for efficient and selective transduction of olfactory sensory neurons

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma). Overexpression of ZIC1 suppresses the growth of group 3 medulloblastoma models, whereas it promotes the proliferation of SHH medulloblastoma precursor cells. SHH medulloblastoma ZIC1 mutants show increased activity versus wild-type ZIC1, whereas G4 medulloblastoma …

Real-World Experiences With Vmat2 Inhibitors In Pediatric Hyperkinetic Movement Disorders, Sujal Manohar, Jennifer Jacobe, Rebecca Berger, Joseph Jankovic, Mariam Hull

Faculty, Staff and Students Publications

Background: Vesicular monoamine transporter 2 (VMAT2) inhibitors are often prescribed for the treatment of hyperkinetic movement disorders such as tics, stereotypy, tardive dyskinesia and chorea. These dopamine depleters have been FDA approved in adults for the treatment of chorea in Huntington's disease and tardive dyskinesia. Use of VMAT2 inhibitors in pediatric hyperkinetic movement disorders, however, is limited due to lack of pediatric FDA approval. We review the real-world prescribing practices and patient experiences with VMAT2 inhibitors in children.

Methods: We performed a retrospective chart review of patients treated with VMAT2 inhibitors at a pediatric movement disorders clinic from 2011 to …

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years. The resultant regression equation predicts expected TEE from easily acquired variables, such as body weight, age and sex, with 95% predictive limits that can be used …

A Model To Address Healthcare Gaps And Poor Research Participation In Hispanic Patients With Parkinson’S Disease, M Felice Ghilardi, Alessandro Di Rocco, Jennifer Fearday, Donna Sperlakis, Maria Lima, Nora Vanegas-Arroyave, Elisa Tatti, Marcelo Arroyave, Evelyn Stevens, Denise Hernandez, Paulina Latapi-Gonzalez, Meri-Margaret Deoudes, Christiana Evers

Faculty, Staff and Students Publications

Parkinson's disease (PD), a progressive neurodegenerative disorder, manifests with motor and non-motor symptoms. Despite similar incidence, in the US, disease management of Hispanic patients with PD is poorer than that of White non-Hispanics, and their participation in clinical trials does not reflect expected values (well below 5% vs. expected values around 20%). Together with other evidence, these observations are expressions of poor healthcare in Hispanic patients with PD, suggesting underutilization of proper healthcare, social and economic disadvantage, and other factors. The scant participation of Hispanic patients in clinical trials further exacerbates care inadequacy. In this paper, after reviewing evidence of …

Faculty, Staff and Students Publications

Aim of the study: We aimed to translate and validate the Polish version of the MDS-NMS and compare it with the original English version.

Clinical rationale for the study: Non-motor symptoms (NMS) affect a significant portion of the Parkinson's disease (PD) patient population and may negatively impact their quality of life. Non-motor symptoms may contribute to an increased sense of illness among patients and to a greater burden upon their caregivers. It is therefore advisable to develop a Polish validation of a reference scale for diagnosing and assessing the severity of NMS.

Material and methods: The MDS-NMS was translated into …

Conclusion: Based on the available data from …

Optic Nerve Sheath Diameter: Which Axis Should Be Measured?, Jakob Pansell, Tina Thomsson, Emelie Eng, Andreas Wallin, Mohammad Hirzallah

Faculty, Staff and Students Publications

Background and purpose: Optic nerve sheath diameter (ONSD) measured by point-of-care ultrasound (POCUS) is a commonly used non-invasive estimate of intracranial pressure (ICP). However, methodological variations limit standardization of this promising technique. Different imaging axes are identified as one such source of ONSD POCUS methodological variation. This study aimed to evaluate the agreement and diagnostic accuracy for elevated ICP between transverse and sagittal ONSD measurements.

Methods: We conducted a post-hoc analysis of 213 intensive care patients from three prior studies. ONSD was measured in both transverse and sagittal planes, externally (ONSDext) and internally (ONSDint) of the dura mater. Agreement was …
