Evaluating The Genetic Overlap Between Congenital Heart Disease And Neuroblastoma Risk., Aniko Sabo, Andrew F Olshan, Sharon E Plon, Chad D Huff, Philip J Lupo

Faculty, Staff and Students Publications

Children with congenital heart disease (CHD) have elevated neuroblastoma (NB) risk, potentially due to shared neural crest origins. We analyzed rare exonic de novo single-nucleotide variants in 702 CHD and 454 NB trios from the Neuroblastoma Epidemiology in North America Study, Gabriella Miller Kids First Program, and a published cohort. Seven genes, including CHD risk genes POGZ and LZTR1 (linked to Noonan syndrome and Schwannomatosis), showed nominal (p < 0.05) enrichment in both cohorts. CIC, IREB2, POGZ, and PCDHG cluster are associated with neurodevelopmental disorders, supporting shared developmental mechanisms. Findings warrant investigation of pathways linking congenital anomalies and childhood cancer.

Rethinking The Centrality Of Brain Areas In Understanding Functional Organization

Faculty, Staff and Students Publications

Parcellation of the cerebral cortex into functionally modular brain areas is foundational to cognitive and systems neuroscience. Here, we question the central status of brain areas from the perspectives of neuroanatomy and electrophysiology. We argue that the major ostensible determinants of brain function, such as cytoarchitecture and connectivity, seldom produce convergent parcellations. Brain areas themselves are just one of several equally important organizing principles; others include macroscale gradients, distributed networks, layers, columns and patches. We further argue that the evidence for a close correspondence between areal parcellation and cognitive function is weaker than is generally supposed. Indeed, many important cognitive …

Deep Brain Stimulation Response Circuits In Obsessive-Compulsive Disorder, Ron Gadot, Nicole R Provenza, Sameer A Sheth

Faculty, Staff and Students Publications

In the field of deep brain stimulation (DBS), two major themes are currently making significant progress. First, the framework of connectomic DBS, in which circuits that are associated with improvements of specific symptoms are described and targeted to improve and potentially personalize treatment. Second, the concept of brain sensing and adaptive DBS, which aims at identifying neural biomarkers that may guide stimulation in a closed-loop fashion.

In DBS for Obsessive Compulsive Disorder (OCD), substantial progress has been made on both ends, over the last five years. Together, results begin to draw a picture of exactly which circuit is …

13 C-Spirulina Gastric Emptying Breath Test Normative Values In Healthy Children: A Multicenter Study With Comparison To Symptomatic Children, Pippa Simpson, Robert J Shulman

Faculty, Staff and Students Publications

Introduction: Diagnosing pediatric gastroparesis presents a significant challenge due to lack of normative data in children. We aimed to determine normative values for gastric emptying using the nonradioactive 13 C-Spirulina gastric emptying breath test ( 13 C-GEBT) in a large cohort of healthy children (HC) and examine differences compared to children with gastroparesis-like symptoms (GLS).

Methods: A total of 301 HC ages 7-18 years completed the 13 C-GEBT with 10 different breath samples × 4 hours. 13 CO 2 excretion rate (kPCD) was determined by change in 13 CO 2 / 12 CO 2 . Outcome variables included: kPCD at …

Faculty, Staff and Students Publications

Objectives: Abdominal pain is common and associated with high disease burden and health care costs in pediatric acute recurrent (ARP) and chronic pancreatitis (CP). Despite the effectiveness of psychological interventions in other abdominal pain populations, studies have not evaluated these interventions for pediatric pancreatitis pain. We evaluated the feasibility, acceptability, and preliminary efficacy of internet-delivered cognitive-behavioral therapy (CBT) for reducing pancreatitis-related abdominal pain and improving pain interference, anxiety, depression, activity limitations, and health-related quality of life.

Methods: We enrolled 90 adolescents (ages 10-19, 63% female) with ARP or CP and their parents into this randomized placebo-controlled multicenter trial from 15 …

Artificial Intelligence In Allergy And Immunology: Recent Developments, Implementation Challenges, And The Road Toward Clinical Impact, Maria Jose Torres Jaén, Aikaterini Anagnostou, Gerard H Koppelman

Faculty, Staff and Students Publications

Artificial intelligence (AI) is increasingly recognized for its capacity to transform medicine. While publications applying AI in allergy and immunology have increased in number, clinical implementation substantially lags behind other specialties. By mid-2024, over 1,000 US Food and Drug Administration-approved AI-enabled medical devices existed, but none specifically addressed allergy and immunology. This gap partly reflects the field's limited reliance on imaging, which facilitated early AI breakthroughs in radiology and pathology. This narrative review examines recent AI developments, including large language models and AI agents, evaluating their applicability to allergy and immunology practice. We analyze current and potential applications, emphasizing those …

Faculty, Staff and Students Publications

Objective: Children with neurogenic bladder (NGB) are at increased risk for urinary tract infections (UTIs), but there is a lack of guidelines to assist clinicians in diagnosing and treating these children. Our objective was to describe the presentation and treatment of provider diagnosed UTIs in children with NGB compared to children with vesicoureteral reflux (VUR) and to assess the proportion of children with NGB who met a consortium definition of UTI.

Study design: We included children < 18 years old with either VUR or NGB who were diagnosed in the emergency department with a febrile UTI in our multicenter retrospective cohort study. We extracted and compared UTI symptoms and urinalysis results specific to children with NGB to children with VUR. We measured the proportion of UTI diagnoses concordant with the Urologic Management to Preserve Initial Renal Function (UMPIRE) consensus definition of UTI, defined as ≥ 100,000 CFU/mL of 1 or 2 organisms, pyuria, and ≥ two symptoms of UTI.

Results: The most common symptom among all children in the cohort was vomiting (38.8 %). Of the 215 children with NGB, 41.3 % met …

Enteral And Intravenous Supplementation Of Arginine And Citrulline Fail To Prevent Necrotizing Enterocolitis In Preterm Neonatal Pigs, Caitlin Vonderohe, Julia Garcia Mancebo, Valeria Melendez Hebib, Barbara Stoll, Inka Didelija, Sarah Elefson, Mahmoud Mohammad, Brooklynn Earls, Greg Guthrie, Doug Burrin

Children’s Nutrition Research Center Staff Publications

Background: Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants with a morality rate that approaches 50%. Arginine has been widely studied in the field of clinical nutrition as a supplement for patients experiencing critical illness because it can be metabolized into nitric oxide, an important agent for supporting immunity and microcirculation. Citrulline has received less attention but can be metabolized into arginine and has a much longer plasma half-life than arginine. We used the highly translational preterm pig model to determine the effect of intravenous and enteral supplementation of arginine and citrulline on NEC incidence in …

Utility And Utilization Of Transabdominal Ultrasound In Pediatric Patients With Acute Recurrent Or Chronic Pancreatitis, Fuchenchu Wang, Gretchen A Cress, Maisam A Abu-El-Haija, Ankur Chugh, Reuven Zev Cohen, Elissa M Downs, Douglas S Fishman, Cheryl E Gariepy, Matthew J Giefer, Tanja Y Gonska, Amit S Grover, Sohail Z Husain, Douglas Lindblad, Quin Y Liu, Asim Maqbool, Jacob A Mark, Brian A Mcferron, Megha S Mehta, Veronique D Morinville, Kenneth Ng, Robert A Noel, Chee Y Ooi, Emily R Perito, Zachary M Sellers, Andrew T Trout, Yuhua Zheng, Ying Yuan, Mark E Lowe, Aliye Uc, Consortium For The Study Of Chronic Pancreatitis, Diabetes And Pancreatic Cancer

Introduction: The recent US Food and Drug Administration approval of resmetirom for treating metabolic dysfunction-associated steatohepatitis in patients necessitates patient selection for significant fibrosis or higher (≥F2). No existing vibration-controlled transient elastography (VCTE) algorithm targets ≥F2.

Methods: The mAchine Learning ADvanceD fibrosis and rIsk metabolic dysfunction-associated steatohepatitis Novel predictor (ALADDIN) study addressed this gap by introducing a machine-learning-based web calculator that estimates the likelihood of significant fibrosis using routine laboratory parameters with and without VCTE. Our study included a training set of 827 patients, a testing set of 504 patients with biopsy-confirmed metabolic dysfunction-associated steatotic liver disease from 6 centers, …

Cyclic Amp-Dependent Regulation Of Ryanodine Receptors In Healthy And Diseased Hearts, Issam H Abu-Taha, Dobromir Dobrev, Xander H T Wehrens

Faculty, Staff and Students Publications

Cyclic adenosine monophosphate (cAMP) is a critical second messenger in cardiomyocytes, regulating essential cellular functions. Upon G-protein-coupled receptor stimulation, adenylyl cyclase (AC) synthesizes cAMP, which phosphodiesterase (PDE) enzymes subsequently degrade. Recent studies challenge the traditional view of uniform cAMP signaling, revealing nanodomain-specific regulation within cardiomyocytes. This localized cAMP signaling modulates key Ca2+-handling proteins, including ryanodine receptor type-2 (RyR2), through channel-bound protein kinases and PDEs. Additionally, nucleoside-diphosphate kinases (NDPKs), particularly NDPK-C, contribute to cAMP synthesis and RyR2 regulation. Elevated NDPK-C levels in failing hearts correlate with increased cAMP levels, enhanced sarcoplasmic reticulum Ca2+ release, and cardiac arrhythmias. Furthermore, cAMP influences the …

Technical Considerations And Contemporary Literature Review Of The Gore Thoracic Branch Endoprosthesis®, Dora Babocs, Ying Huang, Jorge Miranda, Steven Maximus, Gustavo S Oderich

Faculty, Staff and Students Publications

Thoracic endovascular aortic repair (TEVAR) has become the preferred treatment for various thoracic aortic pathologies, including blunt thoracic aortic injury, aneurysms, and dissections. Involvement of Ishimaru Zone 2 occurs in up to 60% of TEVAR cases requiring extension across the distal aortic arch and left subclavian artery (LSA). Coverage of the LSA without revascularization increases the risk of complications such as upper extremity ischemia, stroke, and spinal cord injury. Therefore, the preservation of LSA perfusion during TEVAR is essential. Cervical debranching remains an effective alternative to preserve flow to the LSA, but it poses risks of bleeding, infection, and nerve …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

BACKGROUND: The management of head and neck cancer relies on multidisciplinary expertise; however, access to tumor boards remains variable. Large language models (LLMs) may support guideline-based decision-making, although performance in complex oncologic scenarios is not well defined.

METHODS: Fourteen synthetic cases based on real tumor board encounters were evaluated. Five blinded comparator arms produced recommendations: a human expert, Non-RAG-GPT-4, Non-RAG-GPT-5, RAG-GPT-4, and RAG-GPT-5. Eight head and neck oncologic surgeons scored each recommendation for appropriateness, clarity, specificity, and feasibility using 5-point Likert scales. Paired permutation testing and inter-rater reliability were assessed.

RESULTS: LLM outputs showed close alignment with expert recommendations. RAG-based …

Novel R Shiny Tool For Survival Analysis With Time-Varying Covariate In Oncology Studies: Overcoming Biases And Enhancing Collaboration, Yimei Li, Yang Qiao, Fei Gao, Jordan Gauthier, Qiang Ed Zhang, Jenna Voutsinas, Wendy Leisenring, Ted Gooley, Corinne Summers, Alexandre Hirayama, Cameron Turtle, Rebecca Gardner, Jarcy Zee, Qian Vicky Wu

Wills Eye Hospital Papers

PURPOSE: Our study is motivated by evaluating the role of hematopoietic cell transplantation (HCT) after chimeric antigen receptor T-cell (CAR-T) therapy for ALL, a debated topic. Because patients may receive HCT at different times after CAR-T infusion or never, HCT post-CAR-T should be considered as a time-varying covariate (TVC).

METHODS: Standard Cox models and Kaplan-Meier (KM) curves (naïve method) assume that TVC status is known and fixed at baseline, which can yield biased estimates. Landmark analysis is a popular alternative but depends on a chosen landmark time. Time-dependent (TD) Cox model is better suited for TVC although visualizing survival curves …

Beyond Bile Acids Synthesis: Metabolomics Profiling Highlights Extensive Metabolic Dysregulation And Treatment Response In Ctx

Faculty, Staff and Students Publications

Background: Cerebrotendinous xanthomatosis (CTX) is an inherited metabolic disorder caused by variants in CYP27A1 leading to loss of sterol-27-hydroxylase activity. Sterol-27-hydroxylase generates two classes of bioactive signaling molecules: bile acids and oxysterols. The broader metabolic consequences resulting from perturbations in bile acid and oxysterol signaling and their reversibility with FDA-approved treatment chenodeoxycholic acid (CDCA), are not fully described.

Methods: To establish a comprehensive map of metabolic consequences of CTX, we performed large-scale, untargeted plasma metabolomics in a single subject with CTX, both before and after 6 months of CDCA therapy, and compared results with a reference cohort of over 1100 …

Partial Versus Full Revision In Cementless Single-Stage Exchange For Hip Periprosthetic Joint Infection: A Multicenter Comparative Study With 10-Year Survivorship Analysis, Wenbo Mu, Atthakorn Jarusriwanna, Boyong Xu, Scot A. Brown, Xiaogang Zhang, Alexander Dawes, Javad Parvizi Md, Li Cao

Rothman Institute Papers

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty (THA). Traditional management typically involves full revision to ensure comprehensive infection eradication. However, for patients with well-fixed implants, partial revision in a single-stage cementless approach may provide a viable alternative, potentially preserving bone stock and reducing operative time. The relative efficacy of this approach compared with full revision remains to be fully explored. This multicenter study aims to determine whether partial revision in cementless single-stage exchange surgery offers comparable infection control outcomes to full revision for select patients with well-fixed implants.

METHODS: We conducted …

The origin of cancer is poorly understood because premalignant cells are rarely followed in their native environments. Although the spatial compartmentalization of metabolic functions is critical for proper liver function, it is unknown whether cancers arise from some zones but not others and whether there are metabolic determinants of cancer risk. Zone-specific, mosaic introduction of Ctnnb1 (catenin beta 1) and Arid2 (AT-rich interaction domain 2) mutations, commonly co-mutated genes in hepatocellular carcinoma (HCC), in mouse models showed that position and metabolic context determine clone fates. Ctnnb1/Arid2-driven cancers were much more likely to arise in zone 3. The …

Faculty Research 2026

BACKGROUND: While delivery of supplemental oxygen is a life-saving therapy, exposure to high oxygen, called hyperoxia, leads to increased intensive care unit mortality. Hyperoxia induces oxidant-mediated acute lung injury (ALI) and pulmonary cell death, called hyperoxic ALI (HALI). Elucidating molecular mechanisms in HALI could identify therapeutic targets in ALI.

METHODS: In the current study, we examined in vivo effects of HALI on Beclin-1 (BCN1), which regulates autophagy, and modulation of BCN1 by epidermal growth factor receptor (EGFR). Effects of HALI on BCN1 and autophagy were examined in mice with genetically decreased EGFR (EGFR

RESULTS: In WT, HALI led to increased …

Global Health Articles

INTRODUCTION: The Women First (WF) Preconception Maternal Nutrition trial found greater benefits of small-quantity lipid-based nutrient supplements (SQ-LNS) for intrauterine growth among anaemic versus non-anaemic women at preconception. We investigated whether the benefits of SQ-LNS in improving markers of intrauterine growth occurred evenly across the mild to moderate spectrum of pre-pregnancy anaemia.

METHODS: We analysed WF data (n=2443 maternal-newborn dyads) from Pakistan, India, Guatemala and the Democratic Republic of Congo. Women received SQ-LNS either ≥3 months preconception through pregnancy (Arm 1); starting in the late first trimester (Arm 2); or not at all (Arm 3: control), with all supplementations discontinued …

Fyn-Saracatinib Complex Structure Reveals An Active State-Like Conformation, Josephine C Ferreon, Allan Chris M Ferreon, Choel Kim

Faculty, Staff and Students Publications

Fyn is a Src-family tyrosine kinase implicated in synaptic dysfunction and neuroinflammation across multiple neurodegenerative disorders, including Alzheimer's disease (AD) and Parkinson's disease (PD). Saracatinib (AZD0530) is a potent Src-family inhibitor that has been explored as a repurposed therapeutic; however, its clinical utility is limited by poor kinase selectivity caused by high sequence conservation within Src-family ATP-binding sites. Here, we combine surface plasmon resonance (SPR) and X-ray crystallography to define saracatinib recognition by the Fyn kinase domain (KD). SPR single-cycle kinetics shows that saracatinib binds the isolated Fyn KD and full-length Fyn with low-nanomolar affinity, whereas dasatinib binds with subnanomolar …

Multilevel Analysis Of The Food And Physical Activity Environment And Adult Obesity Across U.S. Counties And States

Faculty, Staff and Student Publications

Adult obesity rates have risen steadily across the United States over the past decade, with more than 40% of adults affected. Persistent geographic and demographic disparities exist in obesity prevalence across the nation. While prior research has examined individual or environmental associated factors of obesity, limited studies have addressed both physical activity and food environments across the nation using multilevel approaches. This cross-sectional ecological study (2014-2024) used a two-level random intercept model to assess the association between county- and state-level factors and adult obesity prevalence across over 3000 U.S. counties nested within 51 states. County-level associated factors included food insecurity, …

School of Psychology

Theoretical accounts typically assume that key features of human socio-cognitive development are universal. This paper reports a large-scale cross-cultural study (17 communities, diverse ethnicities, N = 1,377, 709 female, mean = 5.50 years, -collected March 2022 to January 2024) on gaze following in early childhood. To test for universality, cognitive processing signatures were derived from a computational model treating gaze following as social vector estimation. Results showed substantial variation between communities and individuals. Yet, the processing signature was found in all communities. Individual differences in performance were related to children's familiarity with the data-collection device but not opportunities for social …

Prehospital Transfusion Strategies In Haemorrhagic Shock, Brian Burns, Brodie Nolan, Ian Ferguson, Michael Peddle, Christopher Partyka, Geoff Healy, Stacy Shackelford, Bryan Cotton

Faculty, Staff and Student Publications

Background: Massive transfusion protocols are established in-hospital practices for managing haemorrhagic shock, yet critical bleeding accounts for up to 40% of trauma deaths, with half occurring before hospital arrival. This has driven interest in prehospital transfusion, a concept originating in military settings where early blood product administration during prolonged evacuations demonstrated significant survival benefits. Despite compelling military evidence showing improved 24-h and 30-day survival with prehospital transfusion, civilian adoption faces substantial challenges. Global interest in this domain is increasing, particularly in regions with trauma populations remote from immediate access to major trauma centres.

Main body: Current prehospital transfusion strategies have …
