Master's Projects and Capstones

Background: Adolescent and young adult (AYA) cancer survivors experience unique physical, psychosocial, developmental, and healthcare-related challenges that often persist beyond treatment completion. Although survivorship resources have expanded, gaps in supportive care needs persist. This scoping review examined the supportive care needs, survivorship resources, and barriers to accessing supportive care among AYA cancer survivors.

Methods: A scoping review was conducted following the Arksey and O'Malley framework and reported in accordance with the PRISMA-ScR guidelines. Peer-reviewed literature published between 2000 and 2026 was identified through searches in PubMed and Google Scholar. Studies examining supportive care needs, survivorship resources, or supportive care services …

Phytochemical And In-Vitro Cytotoxic Analyses Of Flavonoid Species Isolated From Chromolaena Leivensis, Luke A. Bryant

Electronic Theses and Dissertations

As a leading cause of death worldwide, cancer and its treatments remain a primary source of interest among researchers. Modern studies are looking into bioselective cytotoxicity to create new chemotherapies that do not have the same harsh side effects as those we use today. Natural product research has a promising future for the development of such treatments. Specifically, polar flavonoids may be the key to a bioselective treatment. Such flavonoid species are native to plants, often within flower petals or within the body. A natural antioxidant, they are designed not to harm healthy cells. This study focuses on the plant …

Breaking The Cycle: From Victimization To Offending Through The Lens Of Human Services, Colette R. Penalosa

Master of Arts in Human Services

The victim-offender overlap challenges the common view that victims and offenders are separately labeled by recognizing that both groups have experienced significant childhood trauma, physical, emotional, and psychological abuse, neglect, and other adverse childhood experiences (ACEs). Current research implies these experiences can increase the risk of offending as they all influence cognitive and behavioral development while leaving criminal behavior undetermined. The purpose of this capstone is to analyze the relationship between childhood victimization and offending from a human service perspective; analyzing the pathways a victim takes on the road to offending. Research conducted will focus on exploring the victim-offender overlap, …

“Something Else To Focus On”: Perinatal Havening And Stress Coping In Pregnant Black Women, Brittany L. Ferrell Young

WUSM Theses and Dissertations – All Programs

Black women in the United States experience maternal mortality at more than three times the rate of white women, a disparity driven by chronic stress rooted in structural racism rather than individual behavior or biology. Accessible, culturally responsive tools for managing stress during pregnancy remain scarce. This mixed-methods pilot feasibility study examined Perinatal Havening, a self-administered psychosensory technique, as a stress management intervention for pregnant Black women. Guided by Lazarus and Folkman's Transactional Theory of Stress and Coping, the study addressed three questions: how Black women experience acute and chronic stress during pregnancy, the acceptability and preliminary influence of Perinatal …

The Efficacy Of Transversus Abdominis Plane Block As An Adjunct To Spinal Anesthesia For Cesarean Delivery: An Evidence Synthesis And Implementation Toolkit, Alyssa Hebert, Alex Potts, Gabriela Robertson

Graduate Theses, Dissertations, and Capstones

Postoperative pain hinders cesarean delivery recovery and overall patient experience. Although spinal anesthesia with intrathecal opioids remains the standard of practice, associated side effects and concerns regarding opioid exposure highlight the need for effective opioid-sparing strategies. Anesthesia providers play a critical role in advancing postoperative pain management through evidence-based protocol development, provider education, and interdisciplinary collaboration to optimize maternal outcomes. The transversus abdominis plane (TAP) block provides somatic analgesia to the anterior abdominal wall by targeting the thoracolumbar nerves (T6–L1) and has increasingly been incorporated into multimodal postoperative pain management strategies for abdominal surgery. Nevertheless, a gap remains in obstetric …

Fall Risk In Community-Dwelling Adults: A Comparison Of English And Spanish-Speaking Individuals, Jesus D. Gomez

Dissertations, 2020-current

Falls are a leading cause of injury-related mortality among middle-aged and older adults. Although vestibular dysfunction, hearing loss, behavioral factors, and social determinants of health have been associated with increased fall risk, few studies have examined these relationships. Furthermore, limited research in audiology and vestibular science has investigated fall-risk vulnerability among Spanish-speaking individuals.

This study aimed to: (1) estimate the prevalence of fall risk among community-dwelling adults and compare prevalence between English-speaking and Spanish-speaking participants; (2) assess the prevalence of previously undiagnosed benign paroxysmal positional vertigo (BPPV) and compare prevalence between language groups; and (3) develop predictive models of fall …

Dosimetric Comparison Between Geometric Centroid And Minimax Isocenter Placement In Single Isocenter Multitarget Stereotactic Radiosurgery Plans In Hyperarc, Matthew Gloudeman

Masters Projects

Single-isocenter multi-target (SIMT) stereotactic radiosurgery (SRS) utilizing Varian HyperArc streamlines clinical workflows but introduces geometric sensitivity for distant outlier lesions when rotational and setup uncertainties are taken into account. The default isocenter location in the HyperArc workspace is the geometric centroid, which is inherently biased toward clusters of lesions. This study evaluates the dosimetric plan quality of an alternative minimax isocenter strategy, which minimizes the maximum lesion-to-isocenter distance, shortening the rotational lever arm to enhance mechanical robustness. Two fractionated SRS (fSRS) plans were generated for ten patients with 3-5 brain metastases using identical beam configurations: one using HyperArc’s default geometric …
