Leveraging Llms To Understand Narratives In Maude Reports, Yuheng Shi, Yang Gong

Faculty, Staff and Student Publications

Interest in using the MAUDE database to investigate adverse events linked to medical devices has been growing. Yet, the narrative sections of these reports remain largely unexplored, leaving valuable insights unutilized and creating an incomplete understanding of these events. To bridge this gap, we employ large language models (LLMs) to analyze and interpret these narratives. Using OpenAI's GPT-4-turbo model, we focused on MAUDE reports involving endoscopic clips to identify uncoded surgical procedures and uncover additional insights. This approach showcases the potential of LLMs in processing narrative content, offering a more efficient and cost-effective alternative to previous methods and supporting the …

This study aims to characterize and compare the functional neural networks associated with different olfactory stimuli, including air, non-social odours, and human body odours. We introduce a novel processing pipeline based on event-related functional magnetic resonance imaging (fMRI) and graph theory for network identification. To ensure the stability and small worldness of the characterized networks, we conduct statistical validations, network modularity assessments, and robustness measurement against local attacks. The key hypothesis is that human body odours (so-called social odours) and non-social odours engage distinct neural networks, particularly in regions responsible for social processing. We found that the posterior medial orbitofrontal …

The endocardium plays a pivotal role in governing myocardial development, and understanding the intrinsic regulatory insights will help apprehend pathological cardiomyopathy. Glycerol-3-phosphate acyltransferase 4 (GPAT4) is an endoplasmic reticulum (ER) membrane anchored protein. While the role of GPAT4 in glycerophospholipid biosynthesis is well established, its function in the ER is less explored. Here, we generate Gpat4 global and tissue-specific knockout mice and identify the essential role of GPAT4 in endocardial development. Deficiency of GPAT4 provokes endocardial ER stress response and enhances ER-mitochondrial (ER-mito) communications, leading to mitochondrial DNA (mtDNA) escape. As a result, the cGAS-STING pathway is triggered to stimulate …

Inflammation drives the initiation and progression of pulmonary hypertension (PH). Platelets, increasingly recognized as immune cells, are activated and increased in the lungs of patients with PH. Platelet activation leads to the release of α-granule chemokines, many of which are implicated in PH. We hypothesized that hypoxia-induced secretion of platelet α-granule-stored proteins and PH would be prevented in Neurobeachin-like 2 knockout (Nbeal2-/-) α-granule-deficient mice. Wild-type (WT) and Nbeal2-/- mice were maintained in normoxia or exposed to 10% hypobaric hypoxia for 3, 14, 21, or 35 days. We observed macrothrombocytopenia, increased circulating neutrophils and monocytes, and increased lung interstitial macrophages (IMs) …

Hypertensive disorders of pregnancy (HDP), including preeclampsia, affect 1 in 6 pregnancies, are major contributors to maternal morbidity and mortality, yet lack precision medicine strategies. Analyzing transcriptomic data from a prospectively-collected diverse cohort (n = 9102), this study reveals distinct RNA subtypes in maternal blood, reclassifying clinical HDP phenotypes like early/late-onset preeclampsia. The placental gene PAPPA2 strongly predicts the most severe forms of preeclampsia in individuals without pre-existing high risk factors, months before symptoms, and its overexpression correlates with earlier delivery in a dose-dependent manner. Further, molecular subtypes characterized by immune genes are upregulated in less severe forms of HDP. …

Challenges In Transitioning From Methadone To Buprenorphine-Naloxone For Chronic Pain Management: Two Cases, Jamal Hasoon, Anvinh Nguyen, Omar Viswanath, Alaa Abd-Elsayed

Faculty, Staff and Students Publications

Background: Methadone is frequently used for chronic pain management due to its long half-life and NMDA receptor activity, making it an effective option for opioid-tolerant patients. Buprenorphine-naloxone is increasingly explored as an alternative for chronic pain and opioid use disorder, offering partial opioid agonism with a ceiling effect on respiratory depression. The transition from methadone to buprenorphine-naloxone remains clinically challenging, requiring careful management to prevent withdrawal and ensure adequate pain control.

Case descriptions: Two patients with chronic pain were transitioned from methadone to buprenorphine-naloxone. The first patient, a mid-40s female, was abruptly switched from methadone 10 mg twice daily dosing …

Epstein-Barr virus (EBV) is associated with a diverse range of lymphomas. EBV-specific T-cell (EBVST) infusions have shown promise in safety and clinical effectiveness in treating EBV-associated lymphomas; however, not all patients respond to T-cell immunotherapies. To identify EBV antigen–specific antibody responses associated with clinical outcomes, we comprehensively characterized antibody responses to the complete EBV proteome using a custom protein microarray in 56 patients with EBV-associated lymphoma who received EBVST infusions in phase 1 clinical trials. Responders (nonprogressors) and nonresponders (progressors) had distinct antibody profiles against EBV. Twenty-five immunoglobulin G (IgG) antibodies were significantly elevated in higher levels in nonresponders than …

The combination of immune checkpoint blockade and chemotherapies is the standard of care for triple-negative breast cancer (TNBC). However, initially, responsive tumors can still develop recurrences, suggesting acquired resistance mechanisms that remain poorly understood. Herein, we discover that TNBC cells surviving anti-programmed cell death protein-1 (anti-PD-1) and chemotherapy treatment accumulate neutral lipids. Disrupting lipid droplet formation in cancer cells reverses resistance and mitigates the immunosuppressive microenvironment. Single-cell RNA sequencing reveals a subset of neutrophils exhibiting a lipid-laden phenotype similar to adjacent tumor cells. Mechanistically, tumor-derived extracellular vesicles carrying lipids, including arachidonic acid (AA), mediate neutrophil reprogramming. Blocking dietary intake of …

Sports cardiology broadly encompasses the cardiovascular care of individuals who place a high premium on habitual exercise, sports performance, and/or sports competition. Some of the essential aspects within sports cardiology include the preparticipation cardiac evaluation and the management of cardiac diseases in athletes. Although most sports cardiology practitioners are trained in adult cardiology, a significant number of individuals who participate in sports are pediatric-aged, < 18 years old. Up to two-thirds of children in middle and high school participate in organized sports or are involved in nonorganized recreational sports. The cardiovascular care of pediatric-aged athletes can be challenging because many of the classic tenets and principles in adult sports cardiology do not fully generalize to pediatrics, and there is a lack of the evidence base that may be present for adult athletes. The epidemiology, presentation, and progression of cardiovascular diseases can be significantly different between pediatric and adult athletes. The evaluation of potential diseases and management considerations may also differ between pediatric and adult athletes. Similar to adults, there are "gray zones" where it is difficult to differentiate between normal exercise-induced cardiac remodeling and true cardiac pathology, but the additional lack of normative standards further complicates assessments in pediatric athletes. Management decisions for pediatric athletes are generally based on limited data but carry substantial short- and long-term implications. Thus, shared decision-making as part of the determination of clinical management strategies and for sports participation is critical and requires the participation of the parents or guardian(s). In this state-of-the-art review, key differences between pediatric and adult-aged athletes are highlighted. Specifically, how to define the "pediatric athlete," consider cardiovascular adaptations observed among pediatric athletes, determine preparticipation screening options and optimal symptom-driven evaluations in children, and consider best practices for pediatric athletes with several key cardiac conditions are detailed. The purpose of this document is to represent the first primary reference available to providers who care for pediatric athletes with cardiovascular concerns.

School of Medicine Publications

Introduction: Hemophilia A (HA) patients (HAPs) with the human leukocyte antigen (HLA)-class-II (HLAII) haplotype DRB1*15:01/DQB1*06:02, and thus antigen presenting cells which express HLAII β-polypeptide chains that form heterodimers of DR15- and DQ6-serotypes, respectively, have an increased risk of developing factor (F)VIII inhibitors (FEIs)—neutralizing antibodies against the therapeutic-FVIII-proteins (tFVIIIs) infused to prevent/arrest bleeding. As DRB1*15:01 and DQB1*06:02 exist in strong linkage disequilibrium, association analysis cannot determine which is the actual risk allele.

Methods: To establish the true risk allele of this haplotype, we analyzed the tFVIII-derived peptides (tFVIII-dPs) bound to either the DR or DQ molecules that comprise the individual HLAII …

Dosage Form Performance Assessment Of Four Commercially Available Turmeric-Containing Dietary Supplements To Inform Clinical Study Design., Bill Gurley Apr 2025

Dosage Form Performance Assessment Of Four Commercially Available Turmeric-Containing Dietary Supplements To Inform Clinical Study Design., Bill Gurley

Oxford ICSB

Clinical studies assessing structure-function claims, safety, phytochemical pharmacokinetics, or drug interaction potential of botanical dietary supplements (BDS) often overlook the disintegration and dissolution characteristics of the administered dosage form. Consequently, inadequate disintegration or dissolution profiles may prevent key study endpoints from being met. Given the high cost of clinical research, no study should proceed without first verifying the disintegration and dissolution performance of the selected dosage form. Failure to do so may compromise the study’s validity and render its findings inconclusive. Assessing dosage form performance, particularly in biorelevant media, is a cost-effective strategy that can provide critical insights for optimizing …

Abstract Title: What Is Chaga? Unique Biochemistry Of The Sterile Conk., Anna Kreynes Apr 2025

Abstract Title: What Is Chaga? Unique Biochemistry Of The Sterile Conk., Anna Kreynes

Oxford ICSB

Fungal based supplements or functional mushrooms are growing in popularity worldwide. Among them, Chaga is attracting increasing attention for its broad immune-modulatory and anti-inflammatory properties. Chaga is unique among “mushroom” supplements as it is technically neither a mushroom (fruiting body), nor a sclerotia, as some researchers assert, but rather a sterile conk or canker that forms on trees, infected and colonized by mycelia of the pathogenic fungus Inonotus obliquus. Commonly associated with birch (Betula spp.), I. obliquus also parasitizes other hardwood species such as alder (Alnus), beech (Fagus), and ash (Fraxinus), found in boreal forests of northern Europe, Asia and …
