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, …

Faculty, Staff and Students Publications

Aims: Early aortic stenosis (AS) detection remains challenging, with many patients presenting late when left ventricular dysfunction may be irreversible. We evaluated whether longitudinal AI-enhanced ECG patterns can predict outcomes years before intervention and assessed the community screening potential of the AK-AVS model.

Methods and results: We conducted two complementary analyses: (1) community validation of the AK-AVS model in 3632 cardiovascular disease-free ARIC participants, and (2) longitudinal trajectory analysis of 7860 ECGs from 2040 TAVR recipients collected up to 10 years pre-procedure. Unsupervised clustering identified distinct AK-AVS trajectories, with mortality associations assessed using Cox regression and net reclassification improvement. In …

Interpretable Ensemble Machine Learning Prediction Of Nonadherence And The Risk Of Nonpersistence Of Targeted Disease-Modifying Antirheumatic Agents In Older Adults With Rheumatoid Arthritis, Yinan Huang, Sandeep K Agarwal

Faculty, Staff and Students Publications

Purpose: Ensemble machine learning (ML) demonstrated potential for improving predictions based on big health care data. We developed and validated interpretable ensemble ML models in evaluating the nonadherence and nonpersistence of biological or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in rheumatoid arthritis (RA).

Methods: This retrospective study used 5% Medicare claims data including older (aged ≥65 years) patients initiating b/tsDMARDs (the index date) between 2013 and 2019, who were diagnosed with RA (the International Classification of Diseases, Ninth and Tenth revision codes). Nonadherence, defined as medication possession ratio < 80%, was evaluated during the 12-month follow-up. Nonpersistence was defined as duration (in days) from the index date until treatment gap ≥60 days during the follow-up period, with death and insurance disenrollment as censoring criteria. Data were split into 75% for model training and 25% for evaluation, with patients' demographics and clinical characteristics measured in the baseline period. Machine learning ensemble classification models (random forest, eXtreme Gradient Boosting [XGBoost], and prediction rule ensembles [PRE]) evaluated the binary nonadherence outcome and ML ensemble survival models (random survival forest, XGBoost survival, and PRE survival) assessed time until nonpersistence. Using the testing cohort, concordance index (C-index) was reported for the ML survival models and AUC was reported for ML classification models.

Findings: We identified 3927 eligible patients with RA (mean age 73 ± …

2020-Current year OA Pubs

Advanced-stage lung squamous-cell carcinoma (LUSC) remains a therapeutic challenge. Although immune checkpoint inhibitors (ICIs) have revolutionized LUSC treatment, only a small subset of LUSC patients can achieve durable clinical benefits, underscoring the need for novel strategies. Emerging immunotherapy strategies have demonstrated early evidence of promise for LUSC patients, particularly multi-specific antibodies and fusion proteins, antibody-drug conjugates, adoptive cell therapies, and cancer vaccines. Additionally, advances in multi-omics and artificial intelligence offer potential for precise immunotherapy by deciphering the complex tumor-immune microenvironment and predicting therapeutic responses. The future of LUSC treatment lies in rational multi-target and biological therapies to boost immune cytotoxicity, …

Single-Cell Multi-Omic Techniques Highlight The Diverse Composition And Intercellular Interactions Of The Vestibular Schwannoma Tumor Microenvironment, Shree S Pari, Sangami Pugazenthi, Albert H Kim, Bhuvic Patel

2020-Current year OA Pubs

Vestibular schwannomas (VS) are tumors arising from Schwann cells of the vestibulocochlear nerve, often leading to hearing loss, gait imbalance, and other neurological complications. Recently, molecular profiling of VS using bulk and single-cell transcriptional and epigenetic approaches has reshaped our understanding of VS pathogenesis and challenged the long-standing view of VS being molecularly homogeneous. These integrative, multi-omic approaches reveal significant differences within VS and highlight diverse Schwann cell subpopulations and their interactions with the tumor microenvironment. Interestingly, these analyses also uncover 2 molecularly distinct groups of VS, one containing Schwann cells with an "Injury-like" phenotype that drives VS progression through …

Finding Significant Hits In Networks: A Network-Based Tool For Analyzing Gene-Level P-Values To Identify Significant Genes Missed By Standard Methods, Sandeep Acharya, Vaha Akbary Moghaddam, Wooseok J Jung, Yu S Kang, Shu Liao, Michael A Province, Michael R Brent

2020-Current year OA Pubs

Finding Significant Hits in Networks (FISHNET) uses prior biological knowledge, represented as gene interaction networks and gene function annotations, to identify genes that do not meet the genome-wide significance threshold but replicate, nonetheless. Its input is gene-level P-values from any source, including omicsWAS, aggregation of genome-wide association studies P-values, CRISPR screens, or differential expression analysis. It is based on the idea that genes whose P-values are low purely by chance are distributed randomly across networks and functions, so genes with suggestive P-values that cluster in densely connected subnetworks and share common functions are less likely to reflect chance and more …

Our findings show that both QCed GATK …

Astrocyte-Specific Deletion Of Lrrc8a Causes Neurological Dysfunction But Not Chronic White Matter Edema, Sven Kerst, Leoni Hoogterp, Marjolein Breur, Gemma M Van Rooijen-Van Leeuwen, Marianna Bugiani, Rajan Sah, Huibert D Mansvelder, Marjo S Van Der Knaap, Rogier Min

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 …

Increased Clinical Frailty Is Associated With Aortic-Related Mortality Following Fenestrated And Branched Endovascular Repair For Thoracoabdominal Aortic Aneurysm, Silvia Chen, Elizabeth Ramirez, Blake E Murphy, Anjali Sribalaskandarajah, Martin Bunker, Joel Kruger, Karina A Newhall, Rebecca A Sorber, Sara L Zettervall, Matthew P Sweet

2020-Current year OA Pubs

OBJECTIVE: Clinical frailty is associated with reduced long-term survival after fenestrated and branched endovascular aortic repair (F/BEVAR). This study assesses the impact of phenotypic clinical frailty on perioperative outcomes and cause of death following F/BEVAR for thoracoabdominal aortic aneurysm.

METHODS: Patients who underwent F/BEVAR at a single institution from 2012 to 2024 were identified. The clinical frailty scale (CFS) was used to determine phenotypic frailty. Patients with a preoperative CFS of ≥4 (vulnerable) and a CFS of < 4 were compared. We used χ

RESULTS: We included 233 patients; 60 (25.8%) had a CFS of ≥4 and 173 (74.2%) had a CFS of < 4. Patients with a CFS of ≥4 were more likely to have chronic obstructive pulmonary disease (53% vs 27%) and were treated for slightly larger aneurysms (72 mm vs 68 mm; P = .04). There were no differences in symptomatic presentation, aneurysm extent, or operative complexity between patient groups. Additionally, there were no differences in perioperative complications including 30-day mortality, stroke, and spinal cord ischemia. Patients with a CFS of ≥4 had an increased length of hospitalization (11.3 days vs 6.9 days; P < .01) and were less likely to return to preoperative functional status (62.7% vs 86.1%; P < .01). The 3-year all-cause and aortic-related mortality rates were 35.2% and 5.7%, respectively. Patients with a CFS of ≥4 had a lower survival at 1 year (74% vs 89%), 3 years (39% vs 73%), and 5 years (25% vs 56%), compared with patients with a CFS of < 4 (P < .01). The most common causes of death among both groups were pulmonary comorbidities (14.0%), oncologic conditions (14.0%), cardiovascular comorbidities (11.2%), and procedure-related complications (11.2%). Patients with a CFS of ≥4 were more likely to die from aortic-related mortality (10.3% vs 5.9%; P = .02), pulmonary comorbidities (15.4 vs 13.2%; P = .04), systemic decline (7.7% vs 1.5%; P = .02), and infection (12.8% vs 7.4%; P = .03). Aortic-related mortality for the entire patient cohort was 2.2% and 5.7% at 1 year and 3 years, respectively. Aortic-related deaths among clinically frail patients were often due to an inability to tolerate further aortic operations (eg, arch repair), and secondary to follow-up nonadherence in patients with a CFS of < 4.

CONCLUSIONS: In an expanded …

RESULTS: The response …

From Damage Signals To Immune Modulators: Oxidized Lipids In Immunometabolic Inflammation, Neetu Srivastava, Xiaoxiao Wan

2020-Current year OA Pubs

Oxidized lipids, once viewed as byproducts of oxidative stress, are now recognized as critical mediators linking metabolism, redox imbalance, and immunity. Generated through enzymatic and nonenzymatic oxidation of polyunsaturated fatty acids, oxidized phospholipids, lipid aldehydes, and oxidized lipoproteins act as context-dependent signals regulating immune activation, resolution, and metabolic adaptation. In metabolic inflammation, these lipids engage scavenger and Toll-like receptors to influence macrophage polarization, dendritic-cell function, and T-cell differentiation. Their context and concentration determine whether oxidized lipids amplify inflammation or promote immune tolerance. Accumulation of these species connects oxidative stress to immune dysfunction, contributing to diseases, such as atherosclerosis, obesity, diabetes, …

Aav Gene Therapy For Mps Iva With Induction Of Immune Tolerance Via Oral Administration Of Epitope Peptides Of N-Acetylgalactosamine-6-Sulfate Sulfatase, Sampurna Saikia, Yasuhiko Ago, Fnu Nidhi, Shaukat Khan, Zhengyu Ma, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis IVA (MPS IVA) is caused by the accumulation of undegraded glycosaminoglycans due to the deficiency of the N-acetylgalactosamine-6-sulfate sulfatase (GALNS) enzyme. MPS IVA manifests as progressive systemic skeletal dysplasia. Gene therapy (GT) is potentially a one-time treatment in which the enzyme is continuously produced, circulated, and delivered to target tissues. However, immune responses to gene products can diminish therapeutic efficacy. We hypothesized that oral delivery of tolerogenic peptides induces immune tolerance to human GALNS (hGALNS) in MPS IVA mice, enhancing therapeutic efficacy. Neonatal mice deficient in mouse GALNS (mGALNS) were treated orally with three T-cell/B-cell epitope peptides or hGALNS …

Goldfinger, Koon Y. Pak, Brian D. Gray, Parkson Lee-Gau Chong

Cardeza Foundation for Hematologic Research

Thrombosis remains a leading cause of cardiovascular morbidity and mortality. During thrombosis, activated platelets and endothelial cells expose phosphatidylserine (PS) on their outer membranes, creating a surface that accelerates clot formation. Current antithrombotic therapies, such as heparin and warfarin, carry significant bleeding risks, highlighting the need for safer alternatives. In response, we developed a PS-targeting liposomal formulation composed of Zn-dipicolylamine (DPA)-cyanine-3[22,22] and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (molar ratio 3:97). This DPA-harboring liposome (DPAL) binds selectively to PS-rich surfaces such as activated platelets and has demonstrated efficacy in reducing thrombosis in mouse models, with minimal bleeding. In the present study, we examined the interaction …
