Executive Functioning And Retained Primitive Reflexes In School-Aged Children, Haley A. Kane, Zeida Gutierrez

Spring 2026 OTD Capstone Symposium

This project aimed to provide teachers with education on EF and RPR and to improve access to educational materials. The education provided definitions of EF and RPR, what deficits in each may present in the classroom, and classroom strategies to mitigate the impact of the skills affected by these deficits. This educational program improved understanding of EF and RPR, evidenced by knowledge-based questions. These materials also increased awareness of RPR and their effects on students, as evidenced by responses to short-answer questions. These results align with the long-term goal of improving the academic performance of students impacted by EF deficits …

While immunotherapy is a promising treatment strategy for cancer, the majority of head and neck squamous cell carcinoma (HNSCC) patients treated with single-agent immunotherapy do not respond. Therefore, researchers are investigating combination treatments with immunostimulatory molecules that can maximize anti-tumor responses. Cyclic dinucleotides (CDNs) are STING agonists that hold promise in combination approaches, but they require frequent intratumoral administration when used in both preclinical models of HNSCC and clinical trials. To reduce administration frequency, we have created a peptide hydrogel–liposome composite system, K2-Lip(CDN), for local and prolonged availability of CDN. We investigated the loading limits of cationic liposomes in both …

A Machine-Learning-Based Tool For Stroke Risk Prediction In Blunt Cerebrovascular Injury: Development And Preliminary Evaluation, Victoria Wagner, Joshua D Preston, Alejandro De Leon Castro, William F Mueller, Jonathan Nguyen, Manuel Garcia-Toca, Elizabeth R Benjamin, S Rob Todd, Jason D Sciarretta

Faculty, Staff and Student Publications

Purpose: Stroke risk correlates with the Biffl grading system in blunt cerebrovascular injury (BCVI). Although anti-thrombotic therapy is the mainstay of stroke prevention, no point-of-care clinical decision-support tool exists to guide timing for therapy. We sought to develop an interactive online calculator that incorporates patient-specific demographic and injury characteristics to estimate stroke risk and risk reduction with anti-thrombotic (AT) administration.

Methods: Data from BCVI patients (n = 1,197) at a Level I Trauma Center were retrospectively collected. Six machine learning methods were employed to predict stroke risk with and without AT therapy. Class imbalance was addressed using downsampling and/or class …

ZNRF3 and RNF43 are closely related transmembrane E3 ubiquitin ligases with significant roles in development and cancer. Conventionally, their biological functions have been associated with regulating WNT signaling receptor ubiquitination and degradation. However, our proteogenomic studies have revealed EGFR as the protein most negatively correlated with ZNRF3/RNF43 mRNA levels in multiple human cancers. Through biochemical investigations, we demonstrate that ZNRF3/RNF43 interact with EGFR via their extracellular domains, leading to EGFR ubiquitination and subsequent degradation facilitated by the E3 ligase RING domain. Overexpression of ZNRF3 reduces EGFR levels and suppresses cancer cell growth in vitro and in vivo, whereas knockout of …

Single-Cell Tcr Mapping Reveals Spatially Coordinated T Cell States In Head And Neck Cancer, Kelli A Mccord, Emerald Kan, Sean Hyslop, Amanda Y Xia, Colby J Hofferek, James S Lewis, Andreas Wieland, David J Hernandez, Vlad C Sandulache, William H Hudson

Current spatial T cell receptor (TCR) profiling approaches lack the resolution needed to link clonal identity, transcriptional state, and spatial positioning of individual T cells in the tumor microenvironment. Here, we introduce a spatial TCR profiling strategy that resolves individual T cell clones together with their transcriptional states at single-cell resolution and applied the method to human head and neck squamous cell carcinoma. Presumed tumor-specific T cells were broadly dispersed throughout the tumor microenvironment, and cells of the same clone occupied distinct transcriptional states in different locations: Immune-rich regions contained more plastic or progenitor cells, whereas tumor-dense regions were enriched …

Constitutive Ampk Activation Prevents Hepatocellular Carcinoma Development Through Inhibition Of Hnf4Α Activity, Zhen Sun, Bernard Linares, Cassidy Urdiales, Fiyad Alsarmi, Boyuan Sang, Nagireddy Putluri, Jeanine L Van Nostrand

Faculty, Staff and Students Publications

Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality and is largely driven by metabolic disorders such as obesity and type 2 diabetes. The AMP-activated protein kinase (AMPK) is a master regulator of metabolism, and its activation has been proposed as a therapeutic strategy for treating metabolic disorders. However, although AMPK activity is down-regulated in HCC, the precise role of AMPK in HCC development has not been clearly delineated. Here, we investigated the ability of constitutive AMPK activation to prevent HCC development using a constitutively active AMPK transgenic mouse model and a pharmacological AMPK activator. We observed that AMPK …

2020-Current year OA Pubs

INTRODUCTION: Etalanetug (E2814) is designed to delay the clinical progression of Alzheimer's disease (AD) by binding to the microtubule binding region (MTBR) of tau implicated in seeding and spreading of tau pathology. Dominantly inherited Alzheimer's disease (DIAD) is a rare form of the disease (<  1%), having similar changes in the tau distribution and pathology to sporadic AD. Herein, we report the safety, pharmacology and biomarker results of the etalanetug Study 103 in DIAD patients.

METHODS: Study 103 enrolled participants with mild-to-moderate cognitive impairment due to DIAD who received etalanetug intravenously every 4 weeks escalating from 750 mg, 1500 mg, 3000 mg, to 4500 mg. After ascending to 4500 mg, patients received 4500 mg for up to 108 weeks. Tau pathology biomarkers, ptau217 and MTBR-tau243 were measured in CSF. Additional …

PURPOSE: There is a lack of data reviewing the role of predicted cardiac mass ratio (PCMR) in transplant recipients with pulmonary hypertension (PH). In particular, the right ventricular (RV) mass ratio (RVMR) is a component of PCMR not yet studied separately for this purpose. We aimed to review the relationship of PCMR and RVMR with PH in terms of post-transplant overall survival.

METHODS: The United Network for Organ-Sharing (UNOS) database was queried for primary heart transplant (HTx) patients from 2004 to 2023. Predicted RVMR was calculated for donors and recipients. A parsimonious multivariable model Cox model was formed for risk …

Play For All: Promoting Inclusivity And Providing Modifications For Kids With Disabilities Within An Indoor Play Space, Yasmeen Ikbal, Mary Jan Greer

Spring 2026 OTD Capstone Symposium

Children’s environments need to be enhanced to match their developmental levels (Winter & Dempsey, 1994). There is a lack of tools, play equipment, and structures specifically targeted to children with disabilities (Therrien et al., 2022). Lack of opportunities for these children can hinder their development (Mullick, 2013). This capstone intends to educate staff and parents on how to promote inclusivity by increasing their understanding of disabilities, creating accessible environments, adapting activities, and building confidence in supporting children with disabilities to participate in their occupations.

Cerebellar Oligodendrocytic Α-Synuclein Pathology And Dentate Nucleus Neuronal Hypertrophy In Parkinson’S Disease, Diego Iacono, Hui Peng, John Paul Bouffard, Roger Kurlan

Department of Neurology Faculty Papers

Idiopathic Parkinson's disease (iPD) research has historically prioritized basal ganglia dysfunction and neuronal Lewy body pathology, often overlooking cerebellar and non-neuronal cells contributions. This study investigates cerebellar neuropathology in iPD, specifically focusing on neuronal and non-neuronal cells of the dentate nucleus (DN) and its adjacent white matter (DN-WM). We systematically assessed autopsy-confirmed iPD brains vs. age-matched controls using immunohistochemistry and stereology-based morphometry methods. The study evaluated α-synuclein pathology, other common age-related co-occurring pathologies (β-amyloid, Tau, neuroinflammation), myelin integrity (Luxol-Fast-Blue), and neuronal volumetric changes in the DN of the cerebellum. In iPD brains, we identified intracytoplasmic α-synuclein inclusions within oligodendrocytes across …

Characterizing the relationship between DNA methylation and circulating proteins is critical to understanding the epigenetic regulation of the human plasma proteome. Here, we performed an epigenome-wide association study of 5,032 circulating proteins in 1,449 White and 315 Black participants from the Atherosclerosis Risk in Communities cohort. We identified 12,500 significant protein quantitative trait methylation (pQTM)-protein associations involving 1,647 proteins. Among 7,796 unique pQTMs, 14.7% were classified as cis-pQTMs, which were enriched for fundamental cellular processes, whereas trans-pQTMs were predominantly linked to immune-related functions. Trans-pQTMs also exhibited stronger associations with demographic, lifestyle, and clinical traits as compared with cis-pQTMs. We identified …

Background

Although the addition of neoadjuvant immune checkpoint blockade to chemotherapy has improved patient outcome in early triple‑negative breast cancer (TNBC), some patients continue to have poor disease outcomes.

Methods

To characterise neoadjuvant chemotherapy (NAC) resistant cell populations that persist post-NAC, we created a high-resolution single-cell atlas of 129,433 cells from fourteen TNBC patient-derived xenograft (PDX) models with residual disease post-NAC. We identified transcriptionally distinct cancer subpopulations or cell states using unsupervised clustering and characterised‑ their regulatory network as well as clinical associations with treatment response, metastatic progression and survival. Findings were validated using multiple independent TNBC cohorts.

2020-Current year OA Pubs

To efficiently implement plasma and cerebrospinal fluid (CSF) biomarkers for staging and prognosis of Alzheimer disease (AD), we must understand their dynamics across disease progression. We analyzed participants from the Swedish BioFINDER-2 study with mass spectrometry measurements of plasma and CSF tau species, including eMTBR-tau243/MTBR-tau243 and phosphorylation occupancies (%p-tau). Disease duration was estimated using Aβ-PET and tau-PET with the SILA algorithm. Bootstrapped LOESS models showed that %p-tau217 changes earliest, increasing just before Aβ-PET positivity. Other p-tau species changed later, with smaller dynamic ranges and earlier ceiling effects. %p-tau205 and MTBR-tau243 changes aligned with tau-PET positivity onset, while MTBR-tau243-especially plasma eMTBR-tau243-tracked …

Faculty, Staff and Student Publications

Background: Stimulant use disorders (StimUDs), including cocaine and methamphetamine use disorders, remain a major public health concern in the United States with no US Food and Drug Administration (FDA)-approved pharmacological treatments. The early recovery period following stimulant use is marked by sleep disturbances, heightened stress reactivity, and dysregulated reward processing, contributing to high rates of resumption of use. Evidence from animal and human studies supports the orexin neuropeptide system as a promising therapeutic target for minimizing these disruptive mechanisms. Suvorexant, an FDA-approved dual orexin receptor antagonist for insomnia, has previously been shown to improve sleep, reduce stress, and attenuate craving …

External validation supported that it can be used to reliably identify both false …

Phip Suppresses Nurd To Enable The Growth Of Swi/Snf-Mutant Cancers, Hayden A Malone, Francisca N De Luna Vitorino, Benjamin A Garcia, Et Al.

2020-Current year OA Pubs

SWI/SNF chromatin remodeling complexes are perturbed in 20% of all cancers and in several developmental disorders, yet the mechanisms by which these mutations dysregulate transcription and drive disease are poorly understood. To both elucidate these mechanisms and identify vulnerabilities caused by these mutations, we leverage genome-wide CRISPR-Cas9 screening in hundreds of cancer cell lines and identify the chromatin reader protein PHIP as a specific dependency in cancers with broadly disrupted SWI/SNF function. Mechanistically, we reveal that PHIP cooperates with SWI/SNF to facilitate transcriptional activation by ubiquitinating and suppressing subunits of the repressive Nucleosome Remodeling and Deacetylase (NuRD) complex. We demonstrate …

The gut microbiota is crucial to health, yet implementation of microbiota-based therapeutics is limited by the lack of rapid diagnostics. We hypothesize that breath contains gut microbe-derived volatile organic compounds (VOCs) reflecting microbiota composition and metabolism. In healthy children, we found that breath VOC composition (or volatilome), assessed by gas chromatography-mass spectrometry, correlates with gut microbiome composition and function. By capturing exhaled breath from human-stool-colonized and monocolonized gnotobiotic mice, we profiled breath VOCs and discovered that murine breath is also significantly influenced by the gut microbiome. VOCs from cultured gut microbes were identified in vivo in monocolonized gnotobiotic colonized mice. …

Concentration-based fluid biomarkers represent an informative and cost-effective way to detect and monitor Alzheimer's disease (AD) pathology. However, non-AD-related interindividual variation in biofluids can also affect biomarker concentrations. Here, we investigated whether normalization of CSF and plasma biomarkers to reference proteins, such as amyloid-β40 (Aβ40) and non-phosphorylated mid-region tau (np-tau), improves their robustness and reliability of representing AD pathology load. Using the Swedish BioFINDER-2 cohort [n = 1702, 50.7% male, mean (standard deviation) age 68.4 (12.2) years], we compared the associations between tau/Aβ-PET load and fluid biomarkers alone versus biomarkers in a ratio with a reference protein (Aβ40 or np-tau) …
