Aging leads to a progressive decline in overall bladder function resulting in lower urinary tract symptoms and increased susceptibility to infections. However, tissue-specific mechanisms of aging, specifically the contributions of the urothelium, remain elusive. Here, we introduce mouse bladder epithelium-derived organoids (mBEDOs) as a scalable platform to model urothelial aging. mBEDOs from aged mice recapitulate key features of age-associated cellular reprogramming, including oxidative stress, senescence, and DNA damage. We demonstrate the utility of mBEDOs for modeling Uropathogenic Escherichia coli (UPEC) infection, generating assembloids between mBEDOs and macrophages to model epithelial-immune interactions, and genetic perturbation. Using the mBEDO platform, we also …

Objective: Failure to rescue (FTR) is a metric of postoperative care, measuring a center's ability to prevent operative death after a surgical complication. We evaluated trends in and contributors to FTR after proximal aortic surgery at a high-volume institution.

Methods: Of 4180 patients in our single practice who underwent open proximal aortic repair from 1990 to 2024, 1304 (31.2%) had at least 1 of 4 FTR-related complications identified by the Society of Thoracic Surgeons (STS). Operative death was defined as death within 30 days of surgery or before hospital discharge or transfer. We analyzed FTR rate by specific complication, including …

Cyclic Amp-Dependent Regulation Of Ryanodine Receptors In Healthy And Diseased Hearts, Mohit M Hulsurkar, Isabelle Ong, Joshua A Keefe, 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 …

Faculty, Staff and Students Publications

A 7-year-old girl presented with a 10-day history of generalized purpura and petechiae. The eruption began with a solitary violaceous macule on the trunk and progressed within 1 week to multiple oval and round dark-red to violaceous purpuric macules, ecchymoses, and petechiae affecting the face, trunk, and extremities. Lesions were distributed parallel to skin cleavage lines with a characteristic “Christmas-tree” pattern on the back (Fig 1). No oropharyngeal lesions were noted on examination, and the patient denied sore throat or oral discomfort. She reported no pruritus, pain, fever, or systemic symptoms.

Faculty, Staff and Students Publications

Background/introduction: Cardiovascular-kidney-metabolic (CKM) syndrome was recently identified as a cardiometabolic disorder that incorporates chronic kidney disease with the metabolic syndrome (MetS). REDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial) was an international, double-blind, placebo-controlled trial that randomized hypertriglyceridemic (TG, 150-499 mg/dL) statin-treated patients with established cardiovascular disease (CVD) or diabetes and multiple CVD risk factors to icosapent ethyl (IPE) or placebo (4 grams/day). It is unknown if renal insufficiency added to MetS confers incremental CVD risk in secondary prevention patients without diabetes and if IPE lowers that risk.

Methods: The current study evaluated the secondary prevention patient subgroup with …

Rethinking The Centrality Of Brain Areas In Understanding Functional Organization, Benjamin Yost Hayden, Sarah R Heilbronner, Seng Bum Michael Yoo

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 …

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 …

Dolichocolon Is Common In Pediatric Gastroenterology Patients With Constipation And Associated Complaints, David Simon, Donovan Berens, Raul Zambrana Valenzuela, Arvind Mohan, Partha Chakraborty, Timot Kellermayer, Eric H Chiou, Craig L Jensen, Ricardo A Arbizu, Marla B K Sammer, Richard Kellermayer

Faculty, Staff and Students Publications

Objectives: Dolichocolon (DC), classified under International Classification of Diseases, Tenth Revision (ICD-10) code Q43.8 ("Other specified congenital malformations of intestine"), refers to an elongated or redundant large intestine. Recent studies in adults indicate a role for dolichocolon in constipation and disorders of gut-brain interaction. Contrast enema (CE) imaging is commonly used to identify DC, typically defined as a sigmoid colon extending above, or a transverse colon descending below, the iliac crest line. Despite its potential relevance, the prevalence and clinical significance of DC in pediatric gastroenterology remain poorly understood.

Methods: This retrospective study assessed the prevalence of DC in pediatric …

Bet Inhibitor-Based Combinations Targeting Novel Dependencies In Mecom-Rearranged (R) Aml, Christine E Birdwell, Warren Fiskus, Christopher P Mill, Tapan M Kadia, Naval Daver, Courtney D Dinardo, Koji Sasaki, John A Davis, Kaberi Das, Hanxi Hou, Antrix Jain, Anna Malovannaya, Lauren B Flores, Rasoul Pourebrahim, Selina Yuan, Xiaoping Su, Michele Ceribelli, Kapil N Bhalla

MECOM rearrangement in AML involves either inv(3)(q21;q26.2) or t(3;3)(q21;q26.2), where the dislocated GATA2 enhancer drives overexpression of the transcriptional regulator EVI1, causes concomitant GATA2 repression, and promotes AML progression, aggressive phenotype and therapy refractoriness. Treatment with BET protein inhibitor (BETi) induces in vitro and in vivo efficacy in MECOM-r AML cells. Utilizing an unbiased, high-throughput drug screen, focused on mechanistically-annotated drugs, we identified BRD4, PIK3CA, mTOR, BCL-xL and XIAP as dependencies in the MECOM-r AML cells. Monotherapy with mivebresib (BETi), dactolisib (PI3K/mTORi) and LCL161 (IAPi) dose-dependently induced greater lethality in PD MECOM-r versus non-MECOM-r AML cells. RNA-Seq and/or mass spectrometry …

Life-Extending Interventions Do Not Necessarily Result In Compression Of Morbidity: A Case Example Offering A Robust Statistical Approach, Deependra K Thapa, Wasiuddin Najam, Erik S Parker, Xi Rita Wang, Daniel L Smith, Ufuk Beyaztas, James F Nelson, Steven N Austad, Gary A Churchill, David B Allison

Children’s Nutrition Research Center Staff Publications

Despite extensive research on life-extending interventions, rigorous statistical techniques to determine their impact on compression of morbidity (CoM) are rarely used. We present a case example of an analytical method for examining the effect of life-extending dietary interventions on CoM by comparing the rates of decline in vitality and survival toward the end of life. Using data from previous experimental studies in mice, we calculated the average rate of vitality decline by fitting exponential decay models to individual vitality trajectories and compared this rate with the rate of survival decline estimated from Cox proportional hazards model. The results showed that, …

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 …

Duncan NRI Faculty and Staff Publications

Retinal detachment (RD) is a sight-threatening emergency requiring urgent intervention to prevent permanent vision loss. While both environmental and genetic risk factors contribute to RD, its complete genetic architecture remains unknown. Here, we performed the largest whole genome sequencing-based case-control study in RD to date, including data from 7,276 RD cases and 236,741 controls in the UK Biobank. Through variant- and gene-level association analyses, we identified VSX2 as a genetic determinant of RD risk while confirming established associations including FAT3, RDH5, and COL2A1. Gene-level collapsing analysis revealed that rare heterozygous missense variants in VSX2 confer a 2.8-fold …

The Affective Economy Of Toxic Atmospheres: Sensory Governance, Ecological Intelligences And The Performative Politics Of Urban Mosquito Management, Orlando Woods, Creighton Connolly

Research Collection College of Integrative Studies

This paper considers how atmospheres can play a powerful role in troubling the management of nature in the multispecies city. It brings the cyclical nature of atmospheric effects, the affective values and il/logics that determine human responses to non-human threats, and the misguided and potentially deleterious health outcomes that ensue into one analytical frame. Drawing on the empirical case of urban mosquito management in Singapore, it considers how the creation of toxic atmospheres through fogging – blowing insecticides into the air in a bid to kill mosquitoes – is ineffective and sets in motion a cascading series of socio-environmental consequences. …

Sequence And Chemical Specificity Define The Functional Landscape Of Intrinsically Disordered Regions, Iris Langstein-Skora, Ryan J Emenecker, Alex S Holehouse, Et Al.

2020-Current year OA Pubs

Intrinsically disordered regions (IDRs) pervasively engage in essential molecular functions, yet they are often poorly conserved as assessed by sequence alignment. To explore the seeming paradox of how sequence variability is compatible with persistent function, we examined the functional determinants for a poorly conserved but essential IDR. We show that IDR function depends on two distinct but related properties: sequence and chemical specificity. Whereas sequence specificity operates via binding motifs and depends on the precise order and identity of residues, chemical specificity reflects the sequence-encoded chemistry of multivalent interactions across an IDR and depends on local and global chemical properties. …

Computational Single-Neuron Mechanisms Of Visual Object Coding In The Human Temporal Lobe, Runnan Cao, Jie Zhang, Jie Zheng, Yue Wang, Peter Brunner, Jon T Willie, Shuo Wang

2020-Current year OA Pubs

Understanding how the human brain encodes visual objects involves deciphering the neural computations and circuits in the temporal lobe. Here, we recorded intracranial EEG from the human ventral temporal cortex (VTC) and medial temporal lobe (MTL), as well as single-neuron activity in the MTL, to investigate the computational mechanisms of neural object coding. The VTC exhibited axis-based feature coding, and a neural feature space could be constructed using VTC neural axes, within which visual objects clustered according to high-level categorical relationships. Importantly, MTL neurons encoded receptive fields within this VTC neural feature space, exhibiting selective responses to objects that shared …
