Staff Education To Providers Prescribing Glp-1 Medications For The Treatment Of Obesity, Madeleine Williams Aug 2026

Staff Education To Providers Prescribing Glp-1 Medications For The Treatment Of Obesity, Madeleine Williams

Walden Dissertations and Doctoral Studies

The utilization of glucagon-like peptide 1 (GLP-1) medications has skyrocketed over the past 5–8 years, with an average weight loss of 15–21% of initial weight. Unfortunately, not all providers offer evidence-based patient education when starting a GLP-1 medication for the treatment of obesity. A practice gap I have identified is the lack of consistent evidence-based education providers utilize when prescribing GLP-1 for obesity treatment in the primary care setting.

Department of Neurology Faculty Papers

Group A Streptococcus (GAS) infections cause neuropsychiatric complications in children, but the mechanisms linking peripheral infection to brain dysfunction remain unclear. Using mouse genetics, single-cell RNA sequencing, and spatial transcriptomics, we show that GAS infections induce inflammatory transcriptional programs in microglia and brain endothelial cells (BECs), accompanied by loss of blood-brain barrier (BBB) gene expression in female mice. Spatial transcriptomic analyses reveal that GAS-responsive microglia localize near infiltrating CD4+ T cells. Several microglial chemokines induced in mice are elevated in sera from affected patients. Deletion of GM-CSF in CD4⁺ T cells partially reduces microglial chemokine gene expression, without restoring BBB …

Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards Aug 2026

Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards

Discovery Day - Daytona Beach

Title: Simulating Pacemakers and Heartbeat Recovery Through Mathematical Modeling   This study utilizes the Fitzhugh-Nagumo model to simulate cardiac electrical activity and the regulatory role of pacemakers through ordinary differential equations (ODEs). By defining the rate of change for membrane voltage, 𝑑𝑣/dt, and a recovery variable, 𝑑𝑤/dt, the model captures the heart's excitability and resting states. Central to the analysis is the stimulus current parameter, which represents the "kick" provided by a pacemaker to correct flatline conditions or weak heartbeats. Using Euler’s method for numerical integration, the research compares unstable cardiac rhythms against corrected periodic oscillations. Additionally, the project implements vector …

MALT1 protease is an intracellular signaling molecule that promotes tumor progression via cancer cell-intrinsic and cancer cell-extrinsic mechanisms. MALT1 has been mostly studied in lymphocytes, and little is known about its role in tumor-associated macrophages. We show that MALT1 is expressed in glioblastoma (GBM)-associated macrophages. Mechanistically, GBM tumor cells induce a MALT1-NF-κB signaling axis in macrophages, leading to enhanced macrophage migration and polarization toward an immunosuppressive ('M2-like') phenotype. Inactivation of MALT1 protease promotes transcriptional reprogramming that reduces migration and restores a macrophage anti-tumor 'M1-like' phenotype. Preclinical in vivo analysis shows that MALT1 inhibitor treatment results in immuno-reactivity of GBM-associated macrophages …

Translational Reading Frame Predicts The Pathogenicity Of C-Terminal Frameshift Deletions In Mecp2, Jacky Guy, Elena Hein, Beatrice Alexander-Howden, Timur Von Bock Und Polach, Tricia Mathieson, Benjamin P Kleinstiver, Huda Y Zoghbi, Adrian Bird Aug 2026

Translational Reading Frame Predicts The Pathogenicity Of C-Terminal Frameshift Deletions In Mecp2, Jacky Guy, Elena Hein, Beatrice Alexander-Howden, Timur Von Bock Und Polach, Tricia Mathieson, Benjamin P Kleinstiver, Huda Y Zoghbi, Adrian Bird

Duncan NRI Faculty and Staff Publications

Mutations in the MECP2 gene cause the severe neurological disorder Rett syndrome. A cluster of frameshift-causing C-terminal deletions (CTDs) removes ~100 amino acids and accounts for approximately 10% of RTT-causing mutations. Their pathogenicity is unexpected because this C-terminal domain is dispensable in mice. Analysis of pathogenic and benign human MECP2 variants reveals that some individuals with apparently typical CTDs do not develop Rett syndrome, confirming that C-terminal truncations are not intrinsically pathogenic. Using human sequence data and mouse models we show that pathogenicity results from a marked reduction in MeCP2 levels and depends on the presence of a proline proline …

Cigarette smoke promotes bladder tumor growth by enhancing cancer cell survival and proliferation through smoke mediated carcinogens. FASN, a key enzyme in fatty acid synthesis, is dysregulated in many cancers and correlates with aggressive phenotypes. In this study, we demonstrate elevated fatty acid levels and FASN specifically in smokers with bladder cancer. Elevated FASN under smoke exposure imparted epigenetic alterations, particularly histone acetylation, impacts DNA repair and DNA-binding transcription factors which regulate metabolic pathways. Under cigarette smoke, bladder cancer cells undergo a metabolic shift, utilizing glutamine as a major carbon source through reductive carboxylation to fuel fatty acid biosynthesis via …
