Chronic wounds present a major burden to patients, health care professionals, and health care systems worldwide, yet treatment options remain limited and often ineffective. Although initially promising, growth factor-based therapies displayed limited and underwhelming effectiveness largely due to poor bioavailabilbioity and impaired receptor function within the chronic wound microenvironment. Here we demonstrate that chronic wounds exhibit elevated cholesterol synthesis, which disrupts growth factor signaling by sequestering receptors within lipid rafts. To address this, we developed a novel therapy combining growth factors with cyclodextrin in an ECM-mimetic scaffold, enabling localized cholesterol modulation and improved receptor accessibility. We demonstrate that this approach …

Finding Love On The Spectrum: An Analysis Of Social And Romantic Relationships Of Autistic College Students, Kaylee Spinner

Masters Theses

Autism Spectrum Disorder (ASD) is characterized by difficulties in socialization, communication, and developing relationships with others. While many autistic individuals desire to start relationships with others, many do not have a very strong understanding of the use of nonverbal communication or how to develop these connections organically. As autistic individuals have become more open about wanting these resources to form social and romantic relationships, there has been more of a push in the literature to include social skills training for forming social relationships. However, the research on the desire for or development of romantic relationships for autistic individuals is still …

Mindfulness & Mental Health: Balanced Time Perspective As A Mediator, Eddie Trueblood

Masters Theses

Mindfulness is a practice of intentionally paying attention to the present moment in a nonjudgmental way. Being more mindful can decrease symptoms of anxiety, depression, and stress, among other mental and physical health improvements. (Donald et al., 2016; Hofmann et al., 2010; Kabat-Zinn et al.,1992). This study examined if balanced time perspective (BTP) is one of the mechanisms of action of mindfulness in its relationship with depression, anxiety, and stress. BTP refers to a person’s ability to flexibly adapt their time perspective (attention to the past, present, or future, and positive or negative attitudes toward each) to suit the current …

Small Town Voices And Stories: Rural Older Populations And Health Narratives, Wyatt K. Zumbahlen

For older adults, narratives become an essential resource in making healthcare decisions. In rural communities like Coles County, Illinois, these stories are especially important for older adults who are navigating the limited care and services available in the area. This reliance on narratives impacts their willingness to seek care, highlighting the need to recognize the power of stories in empowering older …

Examining Multiple Stakeholder Perspectives On The Acceptability Of Pain-Mitigation As A Tool To Manage Needle Fear, Sarah C M Morton

Theses and Dissertations

Needle fear affects up to 63% of the global adult population and is associated with significant fear-based medical care avoidance (e.g., blood donation refusal, vaccine hesitancy, insulin injection adherence). Current behavioral treatments have low acceptance in this population, and often fail to address the experience of pain associated with needle procedures. Despite the existence of evidence-based pain-mitigation for needle procedures, these interventions are not commonly used in clinical settings. The current study used qualitative methods to examine patient and provider perceptions of: 1) current methods of needle fear management, and 2) the acceptability of pain-mitigation as an effective tool to …

Perspective On Alcohol-Induced Organ Damage Via Autophagy-Dependent Cellular Changes, Ahmed Bakheet, Murugadas Anbazhagan, Shirish Barve, Srinivasan Dasarathy, John Dickinson, Wen-Xing Ding, Terrence Donohue, Thiyagarajan Gopal, Anna Gukovskaya, Kusum K. Kharbanda, John J. Lemasters, Natalia A. Osna, Pal Pacher, Lucy Sloan, Luis F. Vilches, Viswanathan Saraswathi, Xiao-Ming Yin, Zhi Zhong, Paul G. Thomes

Journal Articles: Internal Medicine

Alcohol-induced organ damage is a major global health concern and a leading cause of disability and mortality. In addition to the liver, chronic alcohol consumption adversely affects multiple organ systems, including the cardiovascular and neuromuscular systems, the gastrointestinal tract, adipose tissue, kidneys, pancreas, and the brain. Organ damage begins with necrosis (cell death) followed by tissue injury, which triggers immune responses aimed at tissue repair. However, with continued heavy drinking, these reparative responses transition into inflammatory responses which exacerbate tissue injury and accelerate disease progression. Macroautophagy, commonly referred to as autophagy, is a vital and evolutionarily-conserved digestive process in eukaryotic …

Antibiotic Alternatives And Next-Generation Therapeutics For Salmonella Control: A One Health Approach To Combating Antimicrobial Resistance, Mohamed Saleh, Ashutosh Verma, Khaled A. Shaaban, Yosra A. Helmy

Veterinary Science Faculty Publications

The growing prevalence of antimicrobial resistance has significantly compromised the efficacy of conventional antibiotic-based interventions in controlling Salmonella infections across human and veterinary settings. This growing challenge necessitates a strategic rethinking of pathogen control, prompting the integration of next-generation therapeutics capable of disrupting Salmonella pathogenesis through novel, antibiotic-sparing mechanisms. In this context, a diverse array of emerging alternatives, including bacteriophages, antimicrobial peptides, probiotics, prebiotics, short-chain fatty acids, nanoparticles, and host-directed immunomodulators, have gained prominence as a promising frontier in non-antibiotic therapeutics. These modalities offer targeted approaches to inhibit Salmonella colonization, virulence expression, and persistence, while minimizing collateral damage to the …

Using Educational Intervention To Impact Provider And Nurse Knowledge And Self-Efficacy In Contingency Management At An Sud Clinic, Chinwe Egwudo

Doctor of Nursing Practice Projects

The US opioid epidemic crisis led to 700,000 deaths in 2019 alone. Poor adherence to medications for opioid use disorder (MOUD) strains individuals, families, and the healthcare systems, with rising relapses at the project site highlighting the need for evidence-based intervention. Studies show that contingency management (CM), a behavioral intervention that incentivizes desired behaviors, improves adherence to MOUD. Despite its effectiveness, CM remains underutilized in clinical settings due to healthcare providers’ lack of knowledge and self-efficacy. This project aimed to bridge the knowledge gap by implementing an educational intervention to impact healthcare providers’ knowledge and self-efficacy in applying CM protocols …

Ponnusamy, Maneesh Jain, Mokenge Malafa, Santhamma Bindu, Ahmed Gulzar, Hareesh Nair, Surinder K. Batra, Sushil Kumar

Journal Articles: Biochemistry & Molecular Biology

Pancreatic ductal adenocarcinoma (PDAC) is inherently therapy resistant due to cancer cell-stroma crosstalk across several signaling pathways. Among these, the LIF/LIFR axis has been implicated in cancer cell and cancer-associated fibroblast (CAF) crosstalk. We evaluated the efficacy of EC359, a competitive inhibitor of LIFR, in combination with gemcitabine. EC359 reduced tumor burden by 90% compared to controls and by 55% compared to gemcitabine alone in cancer cell and CAFs co-implannation model. The RNA-seq analysis revealed a significant alteration in extracellular matrix components, stemness, microtubule assembly, and immune response, suggesting simultaneous targeting of cancer cell-intrinsic and stroma-mediated mechanisms by EC359.

Infections With Chlamydia Pneumoniae And Sars-Cov-2 And Alzheimer's Disease Pathogenesis, Alexa Romanella, Maegan Mccall, Rachel Corwin, Alaha Abdul Faruq, Emily Lingo, Sanya Bhambhani, Christine J. Hammond, Brian J. Balin

PCOM Scholarly Works

INTRODUCTION: Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the world, but our understanding of causation is still lacking. A current evidence-based hypothesis proposes that certain infectious agents initiate the neurodegeneration consistent with AD. Two infectious agents correlated to AD pathogenesis are Chlamydia pneumoniae (Cpn), a respiratory obligate intracellular bacterium, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus responsible for the COVID-19 pandemic. Both organisms may predispose susceptible populations to disease manifestations, such as AD.

METHODS: This review focused on peer-reviewed original research and review articles evaluating the potential association of Cpn and SARS-CoV-2 with AD. …

A Case Of Navigating Autism And Atypical Rashes In Dermatology Practice., Benjamin S Kahn, Kathleen Ward, Nedyalko Ivanov, Marcus Goodman

Admitting Science: Problems With Current Admissibility Standards, William O'Donohue, Sneha Gupta

Lewis & Clark Law Review

Attorneys use expert testimony to advance legal positions in courtrooms. Because expert testimony can have tremendous influence over judges and juries, it is admitted only if it meets specific admissibility standards, i.e., Frye and Daubert. These standards provide different admissibility criteria, have been adopted by distinct sets of jurisdictions, and, we argue, are of questionable validity. These standards are attempts to ensure that only knowledge is admissible and are, then, essentially an epistemic matter. Science serves as a proxy for knowledge because science is the epistemic process that has been successful at generating knowledge. However, both epistemology and the philosophy …

Cause Of Death? -- It's Probably Not What's Reported On The Death Certificate, Lauren R. Roth

Lewis & Clark Law Review

In the age of big data, this country has a data problem—inaccurate and incomplete information in death certificates. The problem has long been hidden by the numbers reported—as have the people whose deaths go uncounted, but the COVID-19 pandemic unveiled the scope of the issue. Since the beginning of the pandemic, “excess deaths” (i.e., any deaths above the number predicted by existing mortality models) have increased significantly. Most of these excess deaths are likely attributable to COVID-19 because the decedent was never tested for COVID-19 or it was one of multiple factors contributing to their death. Other deaths are uncounted …
