2020-Current year OA Pubs

Volume-regulated anion channels (VRACs) are central to cell volume homeostasis. They mediate swelling-induced efflux of chloride and organic osmolytes to drive regulatory volume decrease. In the brain, VRACs have been proposed to play a key role in astrocytic volume regulation. Genetic defects in astrocytic VRAC modulating proteins (MLC1, GlialCAM, Aquaporin-4, GPRC5B) cause the leukodystrophy Megalencephalic leukoencephalopathy with subcortical cysts (MLC), characterized by chronic white matter edema and myelin vacuolization. Disrupted VRAC activity in MLC-patient-derived lymphoblasts and primary astrocytes from MLC mice further supports a pathogenic link between defective VRAC activity and MLC. Here, we studied the physiological and pathological consequences …

Vaccination Games Of Boundedly Rational Parents Toward New Childhood Immunization, Wei Yin, Martial L. Ndeffo-Mbah, Tamer Oraby

School of Mathematical & Statistical Sciences Faculty Publications

Infectious diseases harm societies through disease-induced morbidity, mortality, loss of productivity, and inequality. Thus, controlling and preventing them is critical for public health and societal well-being. However, societies can hinder efforts to control the spread of diseases by failing to adhere to public health recommendations, such as through vaccine hesitancy. Various disease-transmission models have been utilized to help policymakers respond to (re)emerging outbreaks. The usefulness of such models in assessing the effectiveness of public health policies is significantly dependent on human behavior. This paper introduces a new model of parental behavior toward a new childhood immunization. The model incorporates societal …

Real-World Effectiveness Of Second-Line Therapies In Advanced Non-Small Cell Lung Cancer: Insights From Propensity-Weighted Comparative Analyses Of Longitudinal Ehr Data, Gary C N Hettinger, Qi Long, Ravi B Parikh

Faculty, Staff and Student Publications

Background: While substantial research has focused on first-line (1L) therapies for advanced-stage non-small cell lung cancer (aNSCLC), less is known about the effectiveness of second-line (2L) treatments following disease progression on 1L. The poor prognosis after 1L progression, limited guidance for 2L treatment, and constraints of clinical trials in addressing these questions underscore the need for real-world comparative effectiveness research.

Methods: We conducted a retrospective analysis to compare real-world overall survival (rwOS) associated with 2L treatments among patients with disease progression during 1L. Eligible patients were selected from Flatiron Health's nationwide electronic health record (EHR)-derived de-identified database. 1L and 2L …

Policy Considerations For Universal Congenital Cytomegalovirus Screening In Colorado: Insights From Minnesota’S Model, Elizabeth Wood

Doctoral Scholarly Projects & Capstones

Congenital cytomegalovirus (cCMV) is the most common congenital infection in developed countries and a leading non-genetic cause of sensorineural hearing loss (SNHL) and neurodevelopmental impairment in children. Despite its significant public health impact, newborn screening policies for cCMV remain inconsistent across the United States. Recent policy developments, including Minnesota’s implementation of universal newborn cCMV screening (2023) and Colorado’s adoption of an expanded-targeted screening approach (2025), have intensified discussion regarding optimal strategies for early detection and intervention. This narrative review synthesizes current evidence on the epidemiology, clinical manifestations, diagnostic methods, treatment options, and long-term outcomes of cCMV, with a particular focus …

Alpha 7 Nicotinic Acetylcholine Receptor Contributes To Long-Term Cognitive Recovery Following Ischemic Stroke, Dustin T Nguyen, Kate Mendoza, Cassandra Hall, Chunfeng Tan, Anjali Chauhan

Faculty, Staff and Student Publications

Stroke is associated with autonomic dysfunction and reduced acetylcholine (ACh), a neurotransmitter critical for cognition. ACh signals in part through the alpha-7 nicotinic acetylcholine receptor (α7nAChR), a ligand-gated ion channel involved in synaptic plasticity, learning, and memory. Impaired α7nAChR signaling has been linked to heightened neuroinflammation and poor acute stroke recovery. Here, we investigated whether α7nAChR contributes to post-stroke cognitive recovery in young male mice. Wild-type (WT) and α7nAChR knockout (α7n0KO) mice underwent 60-min middle cerebral artery occlusion (MCAO). In a pharmacology cohort, the α7nAChR agonist GTS-21 was administered immediately after reperfusion and then daily for 20 days. Cognitive performance …

Individuals with hypoplastic left heart syndrome (HLHS) have an underdeveloped left ventricle and require surgery to reconfigure blood flow for survival. Here we profiled the HLHS right-ventricular microenvironment by single-nucleus RNA sequencing and spatial transcriptomics at birth (before heart failure), after surgery with heart failure and after ventricular assist device (VAD) unloading (reduced hypoxia and volume overload). We show that HLHS cardiomyocytes, both within the heart and when derived from induced pluripotent stem cells, are intrinsically senescent. The HLHS myocardium contained a senescent microvascular niche with endothelial cells, pericytes and YAP-high fibroblasts, consistent with hypoxic and mechanical stress. This senescent …

LONP1 encodes a mitochondrial protease essential for protein quality control and metabolism. Variants in LONP1 are associated with a diverse and expanding spectrum of disorders, including Cerebral, Ocular, Dental, Auricular, and Skeletal anomalies syndrome (CODAS), congenital diaphragmatic hernia (CDH), and neurodevelopmental disorders (NDD), with some individuals exhibiting features of mitochondrial encephalopathy. We report 16 novel LONP1 variants identified in 16 individuals (11 with NDD, 5 with CDH), further expanding the clinical spectrum. Structural mapping of disease-associated missense variants revealed phenotype-specific clustering, with CODAS variants enriched in the proteolytic chamber and NDD variants more broadly distributed. CODAS is caused by biallelic …

Concurrent Vulvar Vitiligo And Lichen Sclerosus: The Importance Of Melanocyte-Specific Immunostains In Resolving Diagnostic Ambiguity, Nabor S Mireles, Kaitlyn Levett, Annie Dai, Abdul Hafeez Diwan, Omid Jalali

Faculty, Staff and Students Publications

Vitiligo and lichen sclerosus (LS) are autoimmune dermatoses that may share overlapping clinical and histopathologic features, posing diagnostic challenges when they occur concurrently. We report a biopsy-confirmed case of vulvar vitiligo and LS in a 61-year-old woman presenting with pruritic, depigmented patches on the labia majora and minora. Histopathologic examination showed epidermal thinning with papillary dermal hyalinization and a dense, band-like lymphocytic infiltrate consistent with LS. Melan-A immunostaining demonstrated a complete absence of epidermal melanocytes, confirming concurrent vitiligo rather than LS-related post-inflammatory hypopigmentation. This case underscores the importance of correlating subtle clinical clues with melanocyte-specific immunostains to distinguish coexistent vitiligo …

Cardiac Catheterization In American Indian/Alaska Native Populations: Empowering Communities, Providers, And Systems Toward Equity, Joseph Burns, Daniel J Penny, Keila N Lopez, Lindsay F Eilers, Athar M Qureshi, Christine J Chung, Jason F Deen

Faculty, Staff and Students Publications

American Indian/Alaska Native (AI/AN) people face numerous health disparities, including alarming rates of cardiovascular morbidity and mortality. These inequities are closely tied to unique social, political, and economic circumstances due to the ongoing consequences of systemic racism. Although poorly described, these cardiovascular inequities extend to adult and pediatric interventional cardiology. AI/AN adults are less likely to undergo cardiac catheterization and are more likely to experience complications. There are no published studies on pediatric interventional cardiology outcomes in AI/AN children. The scarcity of available data underscores the need for novel studies to investigate the epidemiology, sociodemographic associations, and outcomes of AI/AN …

Development Of Retrieval-Augmented Generation-Based Large Language Model For Drug-Induced Liver Injury Using Livertox Data, Ashwin Rao, George Cholankeril, Avegail Flores, Gagan Sood, Terrence E White, Fasiha Kanwal, Hashem B El-Serag

Faculty, Staff and Students Publications

Background: Idiosyncratic DILI is a complex clinical challenge requiring timely and accurate decision support. LiverTox, curated by the National Institute of Health (NIH), offers a comprehensive DILI evidence base, but its encyclopedia-like format hinders point-of-care use. Health care providers increasingly use general large language models (LLMs) for clinical care, raising safety concerns due to LLM hallucinations or misinformation. We hypothesize that retrieval-augmented generation (RAG) integration-grounding LLM responses in LiverTox content-would enable accurate DILI decision support.

Methods: We processed 1343 LiverTox drug monographs into 8759 indexed segments using BioBERT embeddings. We developed a RAG pipeline that employs drug-specific prioritization, section-aware weighting, …

The Evolving Therapeutic Landscape Of Pcsk9 Inhibition, Brett S Mansfield, Yakubu Bene-Alhasan, Christie M Ballantyne, Frederick J Raal

Faculty, Staff and Students Publications

Cardiovascular disease remains the leading cause of death worldwide with low density lipoprotein being a major, yet modifiable, risk factor. Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a central role in regulating low density lipoprotein (LDL) receptor expression. Naturally occurring loss-of-function variants in the PCSK9 gene result in lifelong lower LDL cholesterol (LDL-C) levels and significantly lower risk of atherosclerotic cardiovascular disease (ASCVD), providing strong genetic validation of PCSK9 as a therapeutic target. This insight has driven the development of therapies directed at PCSK9 for the management of hypercholesterolaemia, particularly in patients who fail to meet LDL-C targets despite maximally …

Toward Scientific Rigor: Setting Standards For Indirect Calorimetry Analysis And Reporting, Elizabeth L Lieu, Mark A Herman, Sean M Hartig

Faculty, Staff and Students Publications

Indirect calorimetry determines energy expenditure by measuring respiratory gas exchange. The approach is based on the principle that nutrient metabolism consumes O2 and produces CO2 and water in predictable ratios that can be compared with heat production. Due to the impracticality and high cost of direct calorimetry, indirect calorimetry is the major approach for modern metabolic studies in preclinical models. Despite the broad adoption of this method in rodent phenotyping, the field has lacked standardized methods for analyzing, representing, and sharing these data, limiting scientific progress. The recent review in Nature Metabolism by the International Indirect Calorimetry Consensus Committee (IICCC) …
