From Reactionary To Anticipatory Integrated Action: Novel Environmental Health Surveillance For Mass Gatherings, Benjamin J. Ryan, Michael Donahoo, Danielle Esler, Paul Barach, Benjamin Coghlan, Shelby Garner, Laura M. Langan, John Piispanen, Bryan W. Brooks

College of Population Health Faculty Papers

Advances in AI-driven analytics, human-in-the loop techniques, and wastewater monitoring provide the foundation needed to shift from reactive to anticipatory actions for mass gatherings. Traditional surveillance systems focus on clinical and laboratory-based notification pathways, which often result in tardy actions being implemented. Thus, traditional surveillance is becoming outdated. Mass gatherings pose heightened public health risks and hazards, including trauma; injury and substance misuse; deliberate poisoning; and infectious diseases such as food and waterborne illnesses, sexually transmitted infections, and respiratory diseases. There is also a heightened concern due to reduced vaccination coverage. As a result, future international events such as the …

Infant Sensory Gating And A Developmental Cascade To Autistic Traits And Anxiety, Rebecca F Schwarzlose

2020-Current year OA Pubs

Disruptions to the infant sensory environment can have lasting effects on neural response properties and behavior in both humans and animals. Recent work has begun to highlight an additional factor in infant sensory experience: differences in inhibitory signaling and sensory gating. Converging work from human and animal studies has begun to implicate a developmental cascade by which impaired sensory gating during a sensitive period of neonatal neurodevelopment promotes a phenotype of sensory over-responsivity, autistic traits, anxiety, and other psychiatric challenges. In this Review, I propose a model for this developmental cascade and highlight how differences in infant sensory responsivity represent …

Steroid Hormone Metabolites And Mammographic Breast Density In Premenopausal Women, Ghazaleh Pourali, Kayode A Matthew, Myung Sik Jeon, Chongliang Luo, Gary J Patti, Jingqin Luo, Adetunji T Toriola

2020-Current year OA Pubs

BACKGROUND: Steroid hormones influence breast morphology and cellular proliferation and are associated with breast carcinogenesis. However, their associations with mammographic breast density (MBD) are less studied, particularly in premenopausal women. We, therefore, investigated the associations of steroid hormone metabolites with MBD in premenopausal women.

METHODS: Our study included 700 premenopausal women scheduled for screening mammograms. We analyzed 54 steroid hormone metabolites (Metabolon®) and assessed volumetric measures of MBD including volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV) using Volpara. We investigated associations using linear regression modeling to estimate the covariate-adjusted means of VPD, NDV, and DV, corresponding …

2020-Current year OA Pubs

UNLABELLED: Molecular signatures predict prognosis in hepatocellular carcinoma, but their relevance to transarterial radioembolization (TARE) with yttrium-90 (90Y) is unknown. We aimed to identify baseline and treatment-induced pathways associated with response and nominate biomarkers. Ten transcriptomically diverse human liver cancer cell lines were exposed to escalating activities of glass 90Y microspheres for 10 days. Normalized AUC values quantified sensitivity. Whole-transcriptome RNA sequencing at baseline and after treatment was analyzed with elastic net regression and gene set enrichment. Findings were corroborated by qRT-qPCR and exploratory analysis of pretreatment tumor samples from patients undergoing TARE. Liver cancer cell line responses to 90Y …

A Microenvironment-Driven Hla-Ii-Associated Insulin Neoantigen Elicits Persistent Memory T Cell Activation In Diabetes, Neetu Srivastava, Anthony N Vomund, Rongzhen Yu, Orion J Peterson, Yuqing Yang, David P Turicek, Omar Abousaway, Tiandao Li, Pamela Stone, Aisha Ansar, Rima Melhem, Bo Zhang, Chang Liu, Hao Hu, Chyi-Song Hsieh, Laura Campisi, Emil R Unanue, Ana Maria Arbelaez, Cheryl F Lichti, Xiaoxiao Wan, Et Al.

The antigenic landscape of autoimmune diabetes reflects a failure to preserve self-tolerance, yet how novel neoantigens emerge in humans remains incompletely understood. Here we designed an immunopeptidomics-based approach to probe HLA-II-bound, islet-derived neoepitopes in patients with type 1 diabetes. We uncovered a Cys→Ser transformation, conserved between mice and humans, that reshapes autoreactivity to insulin at the single-residue level. This transformation, which we call C19S, arises from oxidative remodeling of insulin in stressed pancreatic islets and also occurs in cytokine-activated antigen-presenting cells, contributing to a feed-forward loop of neoepitope formation and presentation. Despite involving just one amino acid, C19S is recognized …

Frontline Aspiration Versus Stent Retriever Thrombectomy For M2 Occlusions: Insights From The Star Registry, Michael Gaub, Joshua Osbun, Et Al.

2020-Current year OA Pubs

BACKGROUND: Recent trials have furthered uncertainty regarding the endovascular benefit for medium vessel occlusions (MeVO). Stent retrievers (SR) were employed in the first attempt in most interventional arm participants. We sought to compare outcomes in acute MCA M2 occlusions between frontline aspiration and SR, and to delineate procedural and anatomical covariates associated with differential treatment effect.

METHODS: Retrospective analysis of a multicenter stroke thrombectomy cohort identified cases of MT for M2 occlusions. Unmatched and propensity score-matched (PSM) cohorts were generated comparing frontline aspiration to standalone and combined SR. The primary outcome was functional independence (mRS 0-2) at 90 days. Recanalization, …

A Survey-Based Assessment Of Treatment Preferences For Distal Radius Fractures In Participants Aged 65 Years And Older, Zayd Al Rawi, Elizabeth Graesser, Lindley B Wall

2020-Current year OA Pubs

PURPOSE: The management of distal radius fractures (DRF) in patients aged ≥65 years is debated because there is evidence that operative and nonsurgical treatment yield similar outcomes 1 year after injury. When more than one reasonable treatment option exists, shared decision-making between the patient and physician should be used. This study elicited preferences for the treatment of DRF using a survey of participants aged ≥65 years.

METHODS: A survey for participants ≥65 years was administered using Amazon Mechanical Turk. Participants were presented with a theoretical scenario in which they sustained a DRF, followed by two treatment options (surgery or casting) …

Phase I Trial Of Adp-A2afp Tcr T-Cell Therapy In Patients With Advanced Hepatocellular Or Gastric Hepatoid Carcinoma, Tim Meyer, Benjamin R Tan, Et Al.

2020-Current year OA Pubs

BACKGROUND & AIMS: Patients with advanced hepatocellular carcinoma (HCC) generally experience poor outcomes despite current therapies, necessitating the development of alternative treatments. ADP-A2AFP is an investigational autologous T-cell therapy with an affinity-enhanced T-cell receptor (TCR) targeting alpha-fetoprotein (AFP).

METHODS: We describe a phase I, open-label, first-in-human clinical trial of ADP-A2AFP (NCT03132792) in human leukocyte antigen-eligible participants with AFP-expressing HCC (or other tumor) not amenable to transplant/resection who progressed on, were intolerant to, or refused prior systemic therapy. Participants received lymphodepletion chemotherapy (cyclophosphamide 500 mg/m

RESULTS: Twenty-one participants, 20 with advanced HCC and one with gastric hepatoid carcinoma received ≥1 ADP-A2AFP …

Cutibacterium Adaptation To Life On Humans Provides A Potential C Acnes Infection Biomarker, Md Shafiuddin, Wen-Chi Huang, Gabriel William Prather, Jeffrey Ryan Anton, Andrew Lawrence Martin, Sydney Brianna Sillart, Jonathan Z Tang, Michael R Vittori, Michael J Prinsen, Jessica Jane Ninneman, Chandrashekhara Manithody, Jeffrey P Henderson, Alexander W Aleem, Ma Xenia Garcia Ilagan, William H Mccoy 4th

Propionibacteriaceae appear to have adapted to life on humans during the domestication of cattle. These microbial immigrants formed the genus Cutibacterium, and a descendent of those microbial trailblazers (C acnes) now dominates 25% of human skin. C acnes colonization of human skin requires the protein RoxP. Although all Cutibacteria encode this adaptation to life on humans, nothing like RoxP has been found in any other organism. In this study, we report an extensive assessment of 21 RoxP orthologs, which identified conserved molecular surfaces linked to heme-dependent oligomerization and low pH stability. Our investigation suggests how RoxP helps C acnes dominate …

Coordinated Regulation Of Capping Protein By Carmil And V-1/Myotrophin, John A Hammer, John A Cooper

2020-Current year OA Pubs

Capping Protein (CP) plays a central role in controlling actin filament dynamics in almost all eukaryotic cell types by virtue of its ability to block monomer addition and loss at the barbed end of the actin filament. Like other proteins that control actin assembly, CP is subject to regulation. Here we focus on two direct regulators of CP-CARMIL and V-1/Myotrophin. Specifically, we review recent biochemical, structural, imaging, and cell biological data that argue these two proteins cooperate to create a regulatory cycle for CP that controls its availability, activity, and site of action in the cell. Finally, we discuss unresolved …

Mutations In Hsp40 Co-Chaperone Change The Canonical Interdomain Interactions Stimulating Lgmdd1 Myopathy, Ankan K Bhadra, Geetika Aggarwal, Anshuman Jaysingh, Daniel Chen, Jil Daw, Conrad C Weihl, Heather L True

2020-Current year OA Pubs

Limb-girdle muscular dystrophy D1 (LGMDD1) is a rare, dominantly inherited neuromuscular protein-misfolding chaperonopathy caused by mutations in the Hsp40 co-chaperone DNAJB6, primarily in the glycine-phenylalanine (GF) or J-domains. Currently, no treatments are available, and a challenge in understanding the disease is identifying a specific client protein for DNAJB6 in skeletal muscle. DNAJB6 has homology to the yeast DNAJ family member, Sis1. Our previous research indicated that LGMDD1 GF domain mutants in Sis1 exhibit substrate-specific effects, influenced by Hsp70 activity. Herein, we employed functional assays along with advanced molecular simulation studies to understand the regulatory interdomain interactions in disease-causing mutants of …

Diverse Misfolding Mutant Digestive Enzymes Cause Chronic Pancreatitis Through Common Pathways, Steven J Wilhelm, Grace E Curry, Neel Matiwala, Jianguo Lin, Tran Quach, Mark E Lowe, Miklós Sahin-Tóth, Xunjun K Xiao

2020-Current year OA Pubs

BACKGROUND & AIMS: Increasing evidence suggests that protein misfolding and proteotoxicity is an important mechanism of chronic pancreatitis (CP) in patients with genetic variants. Two mouse models carrying misfolding digestive enzyme variants, CPA1 N256K and PNLIP T221M, recapitulate the human CP phenotype. We hypothesized that both models develop CP through similar disease mechanisms.

METHODS: We conducted a comprehensive analysis of mice aged 1 to 6 months using histology, immunohistochemistry, protein immunoblotting, quantitative polymerase chain reaction (qPCR), transmission electron microscopy (TEM), and RNA sequencing (RNA-seq) analysis to characterize pancreatic pathological changes.

RESULTS: Both homozygous models exhibited CP hallmarks, including progressive acinar …

Airway Management In Emergency Department Thoracotomy: A Narrative Review, Aaron J Lacy, Adam Liebendorfer, Sarah M Guess, Rami S Al-Aref, Anthony P Kronfli, Rachel E Armstrong, Amelia W Maiga, Alexander Bracey, Ryan N Barnicle

2020-Current year OA Pubs

INTRODUCTION: Emergency department thoracotomy (EDT) is a high-risk, life-saving intervention for patients in traumatic cardiac arrest. A critical component of EDT is airway management, typically performed by emergency physicians, yet formal guidance regarding optimal strategies remains limited. Airway management in this setting is uniquely complex due to concurrent anatomic injury, physiologic instability, and the procedural demands of thoracotomy.

DISCUSSION: Endotracheal intubation (ETI) during EDT presents multiple challenges. Anatomic difficulties may arise from facial or cervical trauma, restricted positioning, and the presence of cervical collars. Cognitive load is heightened by the chaotic, multidisciplinary environment, requiring strategies such as pre-briefing, checklists, and …

Identification Of Distinct Subtypes In Immune Tolerance After Hematopoietic Cell Transplantation Using The Prospective Able1.0 Pediatric Study Cohort, Bernard Ng, Shalini Shenoy, Et Al.

2020-Current year OA Pubs

The lack of immune tolerance after hematopoietic cell transplantation (HCT) can result in chronic graft-versus-host disease (cGvHD), which is the primary nonrelapse limitation of successful HCT. To date, immune tolerance has been considered a single biological entity, but we hypothesized that post-HCT immune tolerance could develop through multiple pathways. Using the ABLE network database, which comprises measurements of 75 cell populations, 10 cytokines and chemokines, lymphocyte population telomere length, KRECs and TRECs, and 132 metabolites from the largest pediatric cGvHD cohort (n = 241), we applied clustering analysis to patients with primary immune tolerance (PIT; no acute GvHD [aGvHD] or …

Excellent Outcomes In Feasibility Study Of Radiation-Free Conditioning And Transplant In Pediatric Severe Aplastic Anemia, Mithra Lakshmi Narasimhan, Irem Eldem, Jeffrey J Bednarski, Ginny L Schulz, Robert J Hayashi, Shalini Shenoy

2020-Current year OA Pubs

Severe aplastic anemia (SAA) is treated with a hematopoietic cell transplant (HCT) in the presence of an HLA-matched sibling donor (MSD) with disease-free survival (DFS) of >90%. In the absence of an MSD, immunosuppressive therapy (IST) can induce remission but concerns for relapsed/refractory disease and clonal hematopoiesis persist. IST failure is an indication for HCT. Modern HCT approaches target barriers such as graft rejection (GR), graft-versus-host disease (GVHD), and transplant-related toxicities. Traditionally, total body irradiation (TBI) inclusive HCT conditioning helps decrease GR, but the use of TBI in children increases concerns for late effects such as malignancies. To describe outcomes …

2020-Current year OA Pubs

BACKGROUND: Immunohistochemistry (IHC) testing is the primary method to determine HER2 status at many institutions, often with reflex to in situ hybridization (ISH). DNA- and RNA- based platforms are emerging for HER-2 assessment. While approved IHC algorithms exist for HER2 scoring in breast and gastric carcinomas, neither has been validated in endometrial cancer. This study seeks to compare them and evaluate patterns of DNA and RNA expression.

METHODS: 263 endometrioid endometrial adenocarcinoma (EEA), 275 serous endometrial carcinoma (SEC), and 214 uterine carcinosarcoma (UCS) specimens were randomly selected. Previously stained HER2 IHC slides underwent blinded review by two board-certified pathologists and …

Atomic Models Of The Toxoplasma Cell Invasion Machinery, Jianwei Zeng, Yong Fu, Pengge Qian, Wei Huang, Qingwei Niu, Wandy L Beatty, Alan Brown, L David Sibley, Rui Zhang

2020-Current year OA Pubs

Apicomplexan parasites, responsible for toxoplasmosis, cryptosporidiosis and malaria, invade host cells through a unique gliding motility mechanism powered by actomyosin motors and a dynamic organelle called the conoid. Here, using cryo-electron microscopy, we determined structures of four essential complexes of the Toxoplasma gondii conoid: the preconoidal P2 ring, tubulin-based conoid fibers, and the subpellicular and intraconoidal microtubules. Our analysis identified 40 distinct conoid proteins, several of which are essential for parasite lytic growth, as revealed through genetic disruption studies. Comparative analysis of the tubulin-containing complexes sheds light on their functional specialization by microtubule-associated proteins, while the structure of the preconoidal …

An Integrated Analysis Of Three Medulloblastoma Clinical Trials Refines Risk-Stratification Approaches For Reducing Toxicity And Improving Survival, Kyle S Smith, Jeff M Michalski, Et Al.

2020-Current year OA Pubs

BACKGROUND: The identification of clinical and molecular heterogeneity in medulloblastoma has produced risk-stratified therapy, but establishing the most effective yet least toxic regimens has remained elusive owing to numerous treatment options. To improve risk-stratification, we performed an integrated analysis from three clinical trials.

METHODS: Medulloblastoma patients from ACNS0331/NCT00085735, ACNS0332/NCT00392327, and SJMB03/NCT00085202 were included if they had methylation profiling. Molecular groups [WNT, SHH, Group 3 (G3), and Group 4 (G4)], subgroups, and copy number variations were procured from methylation profiles and mutations from next-generation sequencing. Data was assembled into an interactive portal to capture patient characteristics. Cross-trial comparisons, univariable, and multivariable …

Identifying Disparities In Same-Day Surgery Cancellations: Impact Of Race And Socioeconomic Factors In A Pediatric Health System, Nicole M Santucci, Daniel Alligood, Amanda Maytin-Hevia, Danyi Wang, Kelly Chilson, Jesse Vrecenak, Andrew Yeh, Colin A Martin

2020-Current year OA Pubs

PURPOSE: Same-day surgery (SDS) cancellations have significant implications on patients and hospitals. This study aimed to identify demographic and socioeconomic factors that impact SDS cancellations across a single pediatric health system.

METHODS: A case-control retrospective review captured patients (age < 18) who underwent SDS procedures from July 2022 to August 2024. Patients were included if they underwent any procedure at three operative sites: a tertiary pediatric academic hospital (PAH) and two outpatient surgery centers (OSC). Patients whose SDS was cancelled (n = 2,034) were compared to those whose surgeries proceeded as scheduled (n = 25,573). Patient zip codes were matched to Child Opportunity Index (COI) 2.0 data.

RESULTS: The overall SDS cancellation rate was 7.37 %, with a significantly higher rate observed at the PAH compared to OSC (11.4 % vs 53 %, p < 0.001). Patients with cancelled cases were more likely to identify as Black and have the lowest quintile COI (p < 0.001). Cancelled in preop and no shows were two reasons with the most racial disparities. In a sub-analysis comparing cancelled cases between operating sites, PAH cancelled patients tended to be Black (23.8 % vs 11.7 %, p < 0.001) and have very low COI (20.1 % vs. 10.6 %, p < 0.001).

CONCLUSION: SDS cancellation rates are significantly higher amongst patients who identify as Black and reside in low opportunity neighborhoods. Disparities in cancellation rate are more significant in patients scheduled at the urban PAH compared …
