Faculty Scholarship

Aims: The Managing Epilepsy Well (MEW) Network has led the development, testing and scale-up of epilepsy self-management (ESM). The MEW Integrated Database (MEW DB) is a pooled repository of archival studies that facilitates aggregate analysis. This report describes an implementation evaluation tool for ESM adopters. Methods: Publicly available materials on program implementation, adoption and sustainability as well as readiness surveys used by the MEW Network were reviewed, as were content domains and format styles relevant to ESM implementation. Requirements for data Tiers included: 1) survey Tier should be short (≤6 items) and completed quickly (< 3 min), 2) question and response format should be consistent, 3) data elements are relevant to ESM adopters and 4) the tool should be applicable across ESM programs. Iterative review, discussion and item-ranking yielded a final set of 3 distinct data element Tiers. Results: Implementation data elements assess the characteristics of organization that may be a potential ESM adopter (Tier 1), organizational readiness to ESM implementation (Tier 2) and perceptions of ESM program effects or impact by adopters at the individual and program levels (Tier 3). There are 18 data elements, 6 elements in each Tier. Organizational characteristics reflect health disparities among people with epilepsy and common comorbidities. Implementation readiness barriers include motivational factors, training and resources. Implementation experience/outcomes include perceived ESM duration, credibility, impact, likability and effectiveness. Conclusions: A brief and practical implementation evaluation tool for ESM has potential value and important clinical and policy implications in advancing care for people with epilepsy.

Imaging Hallmarks Of Idiopathic Intracranial Hypertension And Insights Into Pathogenesis, Albalooshy Basimah, Scott Faro, Hsiangkuo Yuan, Kiran Talekar, Prabath Mondel, Enchao Qiu, Joga Chaganti

Department of Radiology Faculty Papers

Idiopathic Intracranial hypertension (IIH), also referred to as pseudotumor cerebri, is a term used to describe increased intracranial pressure in the absence of a known identifiable secondary cause. Despite advancements of neuroimaging techniques, imaging of the pathological underpinnings in the diagnosis of IIH has been limited. Although the causation of IIH has been ascribed to increased Cerebrospinal Fluid production and disordered drainage through the dural sinuses, new evidence shows that the glymphatic system which is an alternate pathway of drainage is likely to play a pivotal role. In this review, we address the pathophysiological underpinnings in the causation of IIH …

One of the most common sites of cancer metastasis is to the bone. Bone metastasis is associated with substantial morbidity and mortality, and current therapeutic interventions remain largely palliative. Metastasizing tumor cells need to reprogram their metabolic states to adapt to the nutrient environment of distant organs; however, the role and translational relevance of lipid metabolism in bone metastasis remain unclear. Here, we used an in vivo CRISPR activation screening system coupled with positive selection to identify acyl-coenzyme A (CoA) binding protein (ACBP) as a bone metastasis driver. In nonmetastatic and weakly metastatic cancer cells, overexpression of wild-type ACBP, but …

Glioblastoma (GBM) remains difficult to treat due to poor drug delivery across the blood-brain barrier and an immunosuppressive tumor microenvironment (TME). Tumor-suppressive microRNAs (miRNAs) offer a promising strategy to reprogram both tumor cells and the TME, but inefficient delivery systems limit their clinical application. We previously reported that tumor-suppressive miR-138 regresses tumor growth in preclinical GBM models. Here, we demonstrate that trypsin digestion of extracellular vesicles (EVs) enhances labeling efficiency with folate (FA), enhancing selective targeting of folate receptor (FR)-positive GBM cells and enabling simultaneous targeting of tumor-associated macrophages (TAMs). FA-labeled trypsinized EVs (tEVs) loaded with miR-138 inhibit tumor growth, …

Identification Of Surrogate Biomarkers For Mucopolysaccharidosis Type Iva, Yasuhiko Ago, Shaukat Khan, Kimberly Klipner, Allison Bradford, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis type IVA (MPS IVA, Morquio A syndrome) is a rare inherited disorder characterized by skeletal dysplasia due to deficient N-acetylgalactosamine-6-sulfate sulfatase activity, resulting in glycosaminoglycan (GAG) accumulation. Identifying accurate biomarkers reflecting clinical severity and therapeutic response remains challenging. This study evaluated potential surrogate biomarkers, including N-terminal pro-C-type natriuretic peptide (NT-proCNP), collagen types I and II, mono-sulfated keratan sulfate (KS), di-sulfated KS, and chondroitin-6-sulfate (C6S), in blood and urine samples from 60 patients ranging from 1 to 62 years of age. NT-proCNP levels were significantly elevated in patients of all ages and negatively correlated with growth impairment, especially after 8 …

In the 5 years since the emergence of the COVID-19 pandemic, the field of wastewater-based epidemiology (WBE) has dramatically expanded with programs implemented across the globe to monitor for SARS-CoV-2 and other viruses of public health concern. However, the best way to use wastewater surveillance data and inform local communities of the utility of wastewater science remains limited and sporadically discussed. Specifically, there is vague guidance regarding interpreting varying levels of viral loads in wastewater for public health significance. While collaborative efforts are key to implementing these community-specific wastewater surveillance programs, effectively using the data for public health decision-making still …

Global Dna Methylation Differences Involving Germline Structural Variation Impact Gene Expression In Pediatric Brain Tumors, Fengju Chen, Yiqun Zhang, Wei Li, Fritz J Sedlazeck, Lanlan Shen, Chad J Creighton

Children’s Nutrition Research Center Staff Publications

The extent of genetic variation and its influence on gene expression across multiple tissue and cellular contexts is still being characterized, with germline Structural Variants (SVs) being historically understudied. DNA methylation also represents a component of normal germline variation across individuals. Here, we combine germline SVs (by short-read sequencing) with tumor DNA methylation across 1292 pediatric brain tumor patients. For thousands of methylation probes for CpG Islands (CGIs) or enhancers, rare and common SV breakpoints upstream or downstream associate with differential methylation in tumors spanning various histologic types, a significant subset involving genes with SV-associated differential expression. Cancer predisposition genes …

Objective: Evaluate the use of tranexamic acid (TXA) and observation as a management option for pediatric patients presenting with posttonsillectomy hemorrhage (PTH). Study Design: Retrospective analysis of a prospectively implemented quality improvement initiative with a historical control comparison group. Setting: Tertiary children's hospital. Methods: Patients < 18 years of age who underwent adenotonsillectomy (AT) and returned to the Emergency Department for PTH were included. Patients who were stable without large volume or active bleeding were given intravenous TXA and admitted for overnight observation. Data were compared in a before-and-after analysis: preprotocol (April 2022 to March 2023) versus postprotocol (April 2023 to March 2024). For cost-effectiveness analysis, we analyzed aggregated claims data from a commercial claims database. Results: Preprotocol 1800 adenotonsillectomies were performed, and 40 procedures were performed for control of hemorrhage (2.2 per 100 AT). Postprotocol 2356 adenotonsillectomies were performed, and 30 procedures were performed to control hemorrhage (1.3 per 100 AT) showing a significant reduction in return to the operating room (relative risk [RR] = 0.59, 95% confidence interval [CI] [0.358, 0.916], P-value.020). There were no reported adverse events attributable to TXA. An estimated 21 surgeries were avoided, and 26 additional patients were observed in the hospital during the postprotocol period, for an estimated net cost savings of $174,970. Conclusion: The implementation of a standardized TXA protocol significantly reduced the need for return to the operating room for PTH in pediatric patients, without complications and with net cost savings to the health care system.

Millions of people in the United States experience a reduced or distorted ability to smell or taste. Chemosensory disorders such as anosmia (the inability to smell), parosmia (distorted smell), or dysgeusia (altered taste) have major impacts on health and quality of life including difficulty sensing dangers such as fire or spoilage, a diminished palatability of food and drink that can negatively influence diet and nutrition, feelings of social isolation, and an increased incidence of frailty, anxiety, and depression. Smell or taste dysfunction can also be symptoms of other health issues, including sinonasal disease, cancer, or neurodegenerative disease. Aging adults are …

Rethinking Congenital Cytomegalovirus: A Narrative Review Of The Clinical, Public Health, And Ethical Challenges Of A Preventable Cause Of Childhood Hearing Loss, M. Peyton Simons, Gauri Mankekar

School of Medicine Faculty Publications

Congenital cytomegalovirus (cCMV) is the most common non-genetic cause of pediatric sensorineural hearing loss, affecting approximately tens of thousands of infants annually in the United States. While cCMV may present symptomatically at birth, many infants are asymptomatic initially and later develop progressive or fluctuating hearing loss, which is often undiagnosed without early screening. Despite advances in diagnostic methods such as polymerase chain reaction (PCR) testing, the absence of a national screening policy in the U.S. results in significant variability in early detection and follow-up care. This narrative review provides an overview of the clinical manifestations, diagnostic strategies, and treatment options …

Acute myeloid leukemia (AML) resides in an immune-rich microenvironment, yet, immune-based therapies have faltered in eliciting durable responses. Bridging this paradox requires a comprehensive understanding of leukemic interactions within the bone marrow microenvironment. We optimized a high-throughput tissue-microarray-based pipeline for high-plex spatial immunofluorescence and mass cytometry imaging on a single slide, capturing immune, tumor, and structural components. Using unbiased clustering on the spatial K function, we unveiled the presence of tertiary lymphoid-like aggregates in bone marrow, which we validated using spatial transcriptomics and an independent proteomics approach. We then found validated TLS signatures predictive of outcomes in AML using an …

Surrogate Trust In The Intensive Care Unit: What Can We Do Better?, Abdul W. Kazi, Phoebe Chun, David Oxman, Erika J. Yoo

Department of Medicine Faculty Papers

BACKGROUND/OBJECTIVES: Previous investigation into patients' trust in medical providers is largely limited to the outpatient setting, where increased trust is associated with improved adherence, satisfaction, and self-reported quality of life. Contrastingly, in the intensive care unit (ICU), patients are frequently incapacitated, and it is surrogates that engage with clinicians for decision making. This pilot study aims to measure and compare surrogate trust in the healthcare system and ICU physicians.

METHODS: We measured surrogate trust in both the healthcare system and providers by administering two domain-specific trust-measuring surveys (the Healthcare System Distrust Scale and a modified Trust in Physicians Scale) to …

Emerging evidence suggests expression from human endogenous retrovirus (HERV) loci likely contributes to, or is a biomarker of, glioblastoma multiforme (GBM) disease progression. However, the relationship between HERV expression and GBM malignant phenotype is unclear. Applying several in silico analyses based on data from The Cancer Genome Atlas (TCGA), we derived a locus-specific HERV transcriptome for glioma that revealed 211 HERVs significantly dysregulated in the comparisons of GBM vs. normal brain (NB), GBM vs. low-grade glioma (LGG), and LGG vs. NB. Our analysis supported development of a unique HERV scoring algorithm that segregated GBM, LGG, and NB. Interestingly, lower HERV …

Faculty, Staff and Student Publications

Liver cancer carries a poor prognosis and incidence continues to increase. The main therapy for unresectable disease > 3 cm in diameter is Transarterial Chemoembolization. Unfortunately, overall survival for these patients has improved little in the past two decades. To address this, we propose a new approach using a chemical reaction in situ. We report here our results in a pilot study using a swine model. Domestic swine (n = 3) were treated in the liver with dichloroacetic anhydride in ethiodized oil. CT imaging was followed 24 h after the procedure by necropsy, histopathology, and mass spectrometry imaging. Animals tolerated the …

Ccaat/Enhancer-Binding Proteins Α And Β Regulate Ovulation And Gene Expression Via Dose- And Stage-Dependent Mechanisms, Hanxue Zhang, Rainer B Lanz, Jimmy Dhillon, Paul D Soloway, Bo Shui, Yi Athena Ren

Faculty, Staff and Students Publications

The preovulatory luteinizing hormone (LH) surge orchestrates complex cellular and molecular events leading to ovulation. CCAAT/enhancer-binding proteins α and β (C/EBPα/β) are transcription factors acutely induced by the LH surge and crucial for ovulation and granulosa cell luteinization. However, biological processes (BPs) and their regulatory mechanisms downstream of C/EBPα/β in the preovulatory ovary are not completely understood. To address this knowledge gap, we generated Cebpa/bfl/fl;Pgr-Cre mutants and compared them with Cebpa/bfl/fl;Cyp19a1-Cre mutant female mice: Cebpa/bfl/fl;Cyp19a1-Cre mutants have undetectable levels of C/EBPα/β throughout the preovulatory stages and do not ovulate, aligning with previous reports; and Cebpa/bfl/fl;Pgr-Cre mutants present gradual depletion of …

Endocrinopathies are frequently the initial presentation of histiocytic neoplasms, which are rare hematologic disorders affecting multiple organ systems. Langerhans cell histiocytosis and Erdheim-Chester disease are 2 such disorders known to infiltrate the hypothalamus and/or pituitary gland, leading to arginine vasopressin deficiency (AVP-D) and anterior pituitary dysfunction (APD) in 20% to 30% of cases, often as the first manifestation. Conversely, histiocytic disorders account for a notable proportion (10-15%) of all pituitary stalk lesions. The diagnosis of histiocytoses is often delayed in such cases due to the nonspecific presentation of endocrinopathies and pituitary involvement. Consequently, endocrinologists are at the frontline and uniquely …
