Quantitatively Assessing The Impact Of The Quality Of Snomed Ct Subtype Hierarchy On Cohort Queries, Xubing Hao, Xiaojin Li, Yan Huang, Jay Shi, Rashmie Abeysinghe, Cui Tao, Kirk Roberts, Guo-Qiang Zhang, Licong Cui

Faculty, Staff and Student Publications

Objective: SNOMED CT provides a standardized terminology for clinical concepts, allowing cohort queries over heterogeneous clinical data including Electronic Health Records (EHRs). While it is intuitive that missing and inaccurate subtype (or is-a) relations in SNOMED CT reduce the recall and precision of cohort queries, the extent of these impacts has not been formally assessed. This study fills this gap by developing quantitative metrics to measure these impacts and performing statistical analysis on their significance.

Material and methods: We used the Optum de-identified COVID-19 Electronic Health Record dataset. We defined micro-averaged and macro-averaged recall and precision metrics to assess the …

Investigation Of Heterosynaptic Long-Term Potentiation Of Non-Nociceptive Synapses, Synaptically Relevant Kinase Discovery, And Virtual Screening For A Pkmz Inhibitor In Hirudo Verbana", Avery Franzen

Dissertations and Theses

There is a considerable lack in efficacy for current chronic pain treatments. One therapy that has gained attention are cannabinoid-based medications. However, preclinical and clinical trials do not produce anti-nociceptive results consistently and occasionally produce pro-nociceptive results. Understanding this ambiguity between anti-nociceptive and pro-nociceptive effects is vital to cannabinoids’ future utilization. One symptom of chronic pain conditions is allodynia in which pain is perceived following non-painful stimuli. This may be due to non-nociceptive afferents activating nociceptive circuitry in an abnormal manner. Using the medicinal leech, Hirudo verbana, we have begun to elucidate mechanisms by which endocannabinoids strengthen non-nociceptive afferent synapses. …

Fiber Photometry Analysis Of Spontaneous Dopamine Signals: The Z-Scored Data Are Not The Data, Conner W. Wallace, Clare Y. Slinkard, Rachael Shaughnessy, Katherine M. Holleran, Samuel W. Centanni, Christopher C. Lapish, Sara R. Jones

Department of Medicine Faculty Publications

Fluorescent sensors have revolutionized the measurement of molecules in the brain, and the dLight dopamine sensor has been used extensively to examine reward- and cue-evoked dopamine release, but only recently has the field turned its attention to spontaneous release events. Analysis of spontaneous events typically requires evaluation of hundreds of events over minutes to hours, and the most common method of analysis, z-scoring, was not designed for this purpose. Here, we compare the accuracy and reliability of three different analysis methods to identify pharmacologically induced changes in dopamine release and uptake in freely moving C57BL/6J mice. The D1-like receptor antagonist …

Perspectives On Demyelinating Disease: An Overview Of Multiple Sclerosis, Nathaniel Howard Williams

Senior Honors Theses

Multiple sclerosis (MS) is a demyelinating disease of central nervous system (CNS), primarily concerning oligodendrocytes, the myelinating cells of the CNS and the neurons that are ensheathed in myelin. MS is the most common demyelinating disease, affecting as many as 300,000 yearly in the United States alone. Much debate centers on whether MS onset is primarily caused by autoimmune reactions or intrinsic dysfunction in oligodendrocytes, which prompts an immune-mediated response. Those who review the current literature on MS may become quickly overwhelmed by the volume and variety of available material. The purpose of this review is to present a …

Cardiac Timing Effects On Response Speed Are Modulated By Blood Pressure But Not Heart Rate Variability In Healthy Young Adults, Xiao Yang, Catalina Roldan, Michael Gazzanigo, Yasmine Nabulsi, Fang Fang

Research and Infrastructure Service Enterprise (RISE) Faculty Publications

Cardiac timing effects reflect the dynamic interplay between interoceptive and exteroceptive processes. Human information processing tends to be facilitated during cardiac diastole and inhibited during systole, reflecting autonomic regulation and the neuromodulation by baroreceptor afferents. Thus, blood pressure (BP) and vagally-mediated heart rate variability (vmHRV) are potential modulators of those effects. Additionally, cognitive control appears to play a critical role in the processes. However, whether cardiac timing effects are influenced by those factors remains unclear. The present study aimed to clarify these relationships. Fifty-one healthy young adults completed three experimental sessions to assess BP, short-term HRV, and cardiac timing effects. …

Implementing A Chatbot To Promote Hereditary Breast & Ovarian Cancer Genetic Screening In Women's Health: Identifying Barriers And Facilitators To Screening Adoption, Easton N. Wollney, Shireen Madani Sims, Luisel J. Ricks-Santi, Elizabeth Eddy, Daniel Wiesman, Carla L. Fisher

Department of Biomedical and Translational Sciences Faculty Publications

Background

To promote genetic screening among women at risk for hereditary breast and ovarian cancer (HBOC), the American College of Obstetricians and Gynecologists recommends that risk assessment be integrated into practice. Chatbots like the Genetic Information Assistant (Gia®) are increasingly implemented to expand access to hereditary genetic screening. Factors that impact chatbot implementation for HBOC risk screening and women's uptake are not fully realized. To refine implementation strategies prior to full scale implementation, we sought to identify women's perceived facilitators/barriers to adopting Gia screening in a rural population within a large healthcare system in the southern United States.

Codon Composition In Human Oocyters Reveals Age-Associated Defects In Mrna Decay, Pavla Brachova, Lane K. Christenson, Nehemiah S. Alvarez

Department of Biomedical and Translational Sciences Faculty Publications

Oocytes from women of advanced reproductive age exhibit diminished developmental potential, but the underlying mechanisms remain incompletely defined. Oocyte maturation depends on translational control of maternal mRNA synthesized during growth. We performed a computational analysis on human oocytes from women < 30 versus ≥40 years and observed that mRNA GC content correlates negatively with half-life in oocytes from young (< 30 yr) but positively with oocytes from aged (>40 yr) women. In young oocytes, longer mRNA half-life is associated with lower protein abundance, whereas in aged oocytes GC content correlates positively with protein abundance. During the GV-to-MII transition, codon composition stratifies stability: codons that support rapid translation (optimal) stabilize mRNA, while slow-translating codons (non-optimal) promote decay. With reproductive aging, GC-containing codons become more optimal and align with increased …

Effects Of High-Frequency Repetitive Transcranial Magnetic Stimulation On Impulse Control Disorders In Patients With Parkinson’S Disease On Dopamine Replacement Therapy, Katherine Muksuris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Parkinson’s Disease (PD) is a debilitating neurodegenerative disorder that causes motor deficits, cognitive impairment, and depression. The mainstay treatment for motor symptoms is dopamine replacement therapy (DRT). DRT takes the form of levodopa or dopamine receptor agonists (DAs) and can be associated with impulse control disorders (ICDs). Currently, the approach to mitigating these side effects is to decrease or stop DRT, which may cause motor symptoms to return, making the management of the disorder more difficult. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation treatment for multiple disorders, including its approved use for smoking cessation. It has also shown …

The Effect Of Hypochlorous Acid On Cultured Osteoblast And Escherichia Coli, Cristina Flaquer Fusté

Graduate Theses/Dissertations

Hypochlorous acid (HOCl), a naturally occurring compound in neutrophils, has been used as an antimicrobial in wound treatment. Osteoblasts, bone-forming cells, within the bone tissue play a large role in bone fracture healing. Orthopedic infections are challenging to treat and highly morbid, including surgical site infection of arthroplasty procedures or infection in the setting of compound fractures. HOCl is being considered as a surgical antiseptic to decrease infections in orthopedic surgical procedures. This study therefore seeks to determine the effects of HOCl on osteoblasts and E. coli. Cultured osteoblasts were incubated with varying concentrations of HOCl to examine osteoblast …

Characterization Of The Overexpression Of Reca Homologs Rad51 And Dmc1 In Tetrahymena Thermophila, Jianna M. Cox

Graduate Theses/Dissertations

RecA homologs, Dmc1 and Rad51, work to repair DNA double-strand breaks (DSBs) within the cell through the recombination of homologous sections of DNA. Dmc1 works to repair programmed DSBs through meiotic recombination, while Rad51 functions to repair both meiotic and non-meiotic DSBs, the latter repaired through the process of homologous recombination repair (HHR). Chemotherapeutics, exogenous agents, work to form DSBs in cancer cells, attempting to inhibit the cell’s growth. A hyper recombinant phenotype is often seen in cancer cells due to the overexpression of RAD51, leading to drug resistance, the persistence of cancers, and an overall poor patient outcome. …
