Streamlining Sepsis Care And Enhancing Antibiotic Administration Efficiency Through Emergency Department Staff Nurse Education, Dafina Jamillah Skinner Nov 2025

Streamlining Sepsis Care And Enhancing Antibiotic Administration Efficiency Through Emergency Department Staff Nurse Education, Dafina Jamillah Skinner

Walden Dissertations and Doctoral Studies

Sepsis is a life-threatening medical emergency that requires rapid identification and treatment. Delays in administering antibiotics are directly associated with increased mortality, longer hospital stays, and higher complication rates. Without intervention, patients faced preventable harm, and the organization risked continued non-compliance with federal quality measures. This Doctor of Nursing Practice (DNP) project implemented a structured educational program for emergency department (ED) nurses to improve knowledge of evidence-based sepsis protocols. The practice-focused question asked: For nurses in the ED, will an educational intervention on sepsis recognition and antibiotic stewardship improve knowledge of timely antibiotic administration and blood culture acquisition? Twenty ED …

The purpose of this quantitative, non-experimental, cross-sectional study, guided by the CAM healthcare model, was to examine relationships among nursing faculty demographics, CAM knowledge, attitudes, and curriculum integration. The Knowledge, Attitudes, and Use of CAM survey was administered to 111 nursing faculty across multiple programs. Data were analyzed using multiple linear regression …


Perception Of Emotion In Autism With Controlled Elicitation (Peace), Austin Gillespie, Rachel E. Dewald Nov 2025

Perception Of Emotion In Autism With Controlled Elicitation (Peace), Austin Gillespie, Rachel E. Dewald

Undergraduate Research Symposium Lightning Talks

It is possible that autistic people find it easier to socialize within their own peer group (Beaupré & Hess, 2006), by recognizing socio-emotional nonverbal cues, due to a shared neurodivergence. To assess this, it would be helpful for researchers to have a database of emotional stimuli, validated for use with autistic individuals. Unfortunately, this does not exist. This current study’s objective is to create such a database that evokes natural emotion, rated by autistic individuals to be used in future research. All participants completed the Alexithymia Scale (TAS-20) which measures the participants’ ability to identify and describe their own emotions …

Inflammaging And Cognitive Decline: A Brief Review Of The Chronic Low-Grade Neural Inflammation Hypothesis, Gage Pompa Nov 2025

Inflammaging And Cognitive Decline: A Brief Review Of The Chronic Low-Grade Neural Inflammation Hypothesis, Gage Pompa

Undergraduate Research Symposium Lightning Talks

This presentation reviews the chronic low‑grade neural inflammation hypothesis as a mechanism linking aging to cognitive decline. Inflammaging refers to persistent, low‑level inflammation that develops with age due to immune dysregulation in the absence of infection. In the brain, this process is often triggered by the accumulation of beta‑amyloid plaques and phosphorylated tau tangles. Microglia attempt to clear these proteins, but their prolonged activation releases inflammatory mediators that damage surrounding neurons. Over time, this sustained neural inflammation contributes to neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, epilepsy, and psychiatric disorders including schizophrenia and major depression. Imaging markers …

Feasibility And Preliminary Efficacy Of Uneven Terrain Gait Training In Lower Limb Prosthesis Users, Gabriel Bacani, Dawn Ruby, Sara Hazen, Katie Bricarell

Undergraduate Research Symposium Posters

Lower limb prosthesis users (LLPUs) often feel less confident walking in their day-to-day lives. Even with rehabilitation, some individuals do not develop the skills and confidence needed to walk across different terrains. Walking practice on varied terrains may be a method for increasing skill and confidence. The purpose of this study is to assess the feasibility of implementing an uneven terrain training program for LLPUs. Three LLPUs completed a series of 12 training sessions on an uneven terrain treadmill. Participants walked for up to 12 trials per session with each bout lasting up to 2 minutes. The terrain increased in …


Supplement Use And Ed Self-Assessment Accuracy, Darin Beasley-Williams Nov 2025

Supplement Use And Ed Self-Assessment Accuracy, Darin Beasley-Williams

Undergraduate Research Symposium Posters

The widespread availability of dietary supplements has contributed to their increased use, with over half of U.S. adults reporting regular consumption. Prior research suggests that supplement use is associated with better overall health, and regulatory legislation has been implemented to mitigate potential adverse effects. One motivation for supplement use may be self-diagnosed health issues; however, incorrect self-diagnoses could lead to inappropriate supplement consumption and potentially contribute to disordered eating patterns. This study examined whether regular supplement users are more accurate in self-identifying an eating disorder. A sample of 511 undergraduate students completed a self-report questionnaire assessing supplement use and eating …

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang Nov 2025

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang

Electronic Theses and Dissertations

Information is encoded and stored in three types of memory: sensory memory (SM), short-term memory (STM), and long-term memory (LTM). SM has a large capacity but retains information for only a brief period. When information transfers to STM, only a limited amount can be stored. Information in STM can then be transferred to LTM, which has a much larger capacity and longer retention time. STM is often conceptualized as working memory (WM) to highlight its role in active information processing. Due to the limited capacity of STM, it is commonly believed that STM serves as the bottleneck for information processing. …

Liver-Directed Base Editing Of Abcc6 Prevents Ectopic Calcification In A Variant-Humanized Mouse Model Of Pseudoxanthoma Elasticum, Lauren C. Testa, Dora Obiri-Yeboah, Hooda Said, Ping Qu, Michael A. Levine, Mohamad-Gabriel Alameh, Kiran Musunuru, Qiaoli Li, Xiao Wang

Department of Biochemistry and Molecular Biology Faculty Papers

Pseudoxanthoma elasticum (PXE) is an autosomal recessive connective tissue disorder characterized by ectopic calcification of elastic fibers throughout the skin, retina, and arteries. It is caused by pathogenic variants in ABCC6 , which encodes a transmembrane transporter that primarily localizes to hepatocytes. Loss of ABCC6 function in hepatocytes leads to systemic deficiency of inorganic pyrophosphate (PPi), a potent inhibitor of calcification; such depletion of PPi from the circulation is responsible for multisystemic ectopic calcification seen in PXE. Therefore, liver-targeted variant correction by genome editing and subsequent restoration of systemic PPi may offer a one-and-done therapeutic approach for PXE. The ABCC6 …

Mantle cell lymphoma (MCL) responds to frontline therapy but is susceptible to relapse. While Bruton's tyrosine kinase inhibitors (BTKi) achieve high response rates, most patients eventually experience disease progression. Predicting responses to subsequent treatments remains challenging due to the lack of an established platform. Heterogeneity in gene alterations and cellular pathways contribute to resistance, complicating treatment approaches. Here, we present a multi-modal profiling platform, targeting key pathways rather than focusing on singular DNA-associated lesions. We identified dysregulated signaling pathways by performing gene expression profiling on 20 MCL samples using a custom MCL MATCH gene set and analyzed the data with …

Src homology 2-domain containing protein tyrosine phosphatase 2 (SHP2), encoded by the Ptpn11 gene (Tyrosine-protein phosphatase non-receptor type 11), is a key downstream effector of PD-1/PD-L1 signaling and is likely important, in addition to immune modulation, in tumor development and vascular homeostasis. SHP2 conveys PD-1 mediated inhibitory signaling in T cells, and is emerging as a therapeutic target. Importantly, there is an association between immune checkpoint inhibitors (ICIs), immune-related adverse events (irAEs), and cardiovascular complications, underscoring the need to understand SHP2’s role in these processes. This review aims to summarize current knowledge on SHP2/PTPN11 biology, its role in immune …

Background: Chorioamniotic membrane separation (CAS) is a recognized complication of fetoscopic laser photocoagulation (FLP) for twin-to-twin transfusion syndrome (TTTS), associated with increased risks of preterm prelabor rupture of membranes (PPROM) and preterm birth (PTB). Although CAS is well described, its incidence and relationship to specific surgical techniques, particularly the method of uterine entry, are not well defined in the published literature. No randomized trials have evaluated whether entry technique influences the risk of CAS.

Methods: We present the protocol for a randomized controlled trial comparing sharp-trocar and Seldinger uterine entry techniques for FLP in TTTS diagnosed between 16 + 0 …

Genes influencing opioid use disorder (OUD) biology have been identified via genome-wide association studies (GWAS), gene expression, and network analyses. These discoveries provide opportunities to identifying existing compounds targeting these genes for drug repurposing studies. However, systematically integrating discovery results and identifying relevant available pharmacotherapies for OUD repurposing studies is challenging. To address this, we've constructed a framework that uses existing results and drug databases to identify candidate pharmacotherapies. For this study, two independent OUD related meta-analyses were used including a GWAS and a differential gene expression (DGE) study of post-mortem human brain. Protein-Protein Interaction (PPI) sub-networks enriched for GWAS …

Mutations in KRAS drive 88% of pancreatic ductal adenocarcinomas (PDAC) and up to 40% of low-grade serous ovarian cancers (LGSOC), making KRAS a long-standing therapeutic target. We previously showed that DIRAS3 binds RAS, forming heterodimers that disrupt RAS clustering and downstream MAPK signaling. Building on this, we developed conformationally constrained DIRAS3-derived peptides using two cyclization strategies and characterized them by NMR and biolayer interferometry. These cyclic peptides attenuate the interaction between KRAS and the BRAF RAS-binding domain, penetrate cells efficiently, and inhibit KRAS nanoclustering on the inner leaflet of the plasma membrane. Functionally, they reduce cell viability and suppress PDAC …

Background: Follistatin is a potent regulator of various TGF-β superfamily members, including myostatin (MSTN) and activin A. Previous studies have shown that follistatin is crucial in enhancing myogenesis during acute muscle injury. The mechanism by which fibro-adipogenic progenitors (FAPs)-specific follistatin influences muscle homeostasis in obese mice remains unknown. Therefore, we investigated the physiological role of follistatin in PDGFRα-positive FAPs in the regulation of muscle homeostasis and exercise in obese mice.

Methods: A PDGFRα-specific follistatin knockout (follistatin KO) mouse model was generated using PDGFRα-GFP-CreERT2 (PDGFRα-GCE) and follistatinflox/flox mice. These mice were fed a 60% high-fat diet (HFD) for 20 weeks, followed …

Faculty, Staff and Students Publications

The gut-microbiome-brain axis is a bidirectional communication system influencing host physiology and overall fitness. While "bottom-up" effects-where gut microbes influence brain function and behavior-are well established, direct evidence for "top-down" modulation-where the brain shapes the gut microbial ecology-remains elusive. Here, we show that the selective expression of the bacterial ion channel mNaChBac in glutamatergic lateral habenula (LHb) neurons increases their bursting activity and leads to endophentypes associated with depression. Importantly, this chronic activation leads to changes in the gut microbiome composition over time, as reflected by shifts in alpha-diversity and alterations in specific microbial taxa. These findings provide direct evidence …
