Women Refugees & Immigrants: What Utahns Need To Know, Susan R. Madsen, Deborah Lin

Marketing and Strategy Faculty Publications

Refugee and immigrant women are an integral part of Utah’s communities, contributing as neighbors, workers, entrepreneurs, caregivers, and advocates. They enrich our state through their diverse perspectives, experiences, and talents. Utah has a long tradition of welcoming newcomers, and our communities are stronger when everyone has the opportunity to belong and contribute. At the same time, research shows that many of the challenges facing Utah women and girls disproportionately affect refugee and immigrant women. Understanding the experiences, needs, and contributions of these women is essential to fostering welcoming, supportive communities so that all Utah women and girls can thrive.

2020-Current year OA Pubs

BACKGROUND: Non-small cell lung cancer (NSCLC) remains the leading cause of cancer-related mortality in the United States, but survival outcomes are shifting with evolving therapies and screening. Recent findings suggest that survival improvements vary across health-care systems, with favorable trends observed in the Veterans Health Administration (VHA). We sought to compare NSCLC survival trends across US health systems.

METHODS: We conducted a retrospective cohort study of patients with NSCLC (2007-2019) using data from the VHA and the National Cancer Database (NCDB), representing the non-VHA US general population. The primary exposure was health system (VHA vs non-VHA), and the primary outcome …

Pharmacy Faculty Articles and Research

Healthcare sustainability is a multidisciplinary field that seeks to mitigate healthcare’s environmental consequences. Antimicrobial stewardship and healthcare sustainability both aim to reduce wasteful resource use while maximizing patient safety. However, a strong partnership between antimicrobial stewardship and healthcare sustainability has yet to develop. To facilitate environmentally sustainable decision-making in antimicrobial prescribing, we developed a web-based calculator (EcoRxChoice (www.ecorxchoice.com)) where users can enter different antimicrobial regimens and compare how much plastic waste each regimen creates. This work was supported in part by the Society of Infectious Diseases Pharmacists (SIDP), reflecting SIDP’s commitment to strengthening sustainability as a practical extension of antimicrobial …

Department of Radiation Oncology Faculty Papers

PURPOSE: Tumor treating fields (TTFields) are FDA-approved for supratentorial glioblastoma, but feasibility in infratentorial tumors remains poorly defined. This simulation study evaluated TTFields dose in brainstem gliomas using patient-specific modeling with scalp-only transducer arrays.

METHODS: MRI and CT imaging from seven patients with brainstem gliomas were used for TTFields planning with MAXPOINT® (Novocure, Switzerland). Clinical target volume (CTV) was defined as enhancing tumor on T1 post-contrast MRI (Gross tumor volume, GTV) plus a 3 mm peritumoral expansion. The platform optimized scalp-only array layouts, and finite element calculations generated maps of local minimum field intensity (LMiFI, V/cm) and local minimum power …

Division of Cardiology Faculty Papers

INTRODUCTION: Physical activity has been associated with improved cardiovascular health outcomes in adults. However, the specific associations between physical activity volume and cardiovascular outcomes in youth athletes are less defined.

METHODS: This study analyzed data from the HeartBytes National Youth Database, compiled from Simon's Heart. Simon's Heart is a nonprofit organization that includes information from sports pre-participation examinations for adolescents. The dataset encompasses demographics, electrocardiogram (ECG) findings, and exercise-related symptoms. Youth athletes' self-reported weekly physical activity volume was classified into four levels: < 2 h, 2-5 h, 5-10 h, and >10 h, with less than 2 h taken as the reference group. Given the physical diMerences among athletes …

Gene Transcriptional Expression Of Cerebral Blood Flow Alterations In Parkinson’S Disease: A Transcription-Neuroimaging Association Study, Jiaqi Cui, Qiane Yu, Haifeng Ran, Kexin Huang, Jie Hu, Tijiang Zhang

Faculty, Staff and Student Publications

Aim: Despite the intimate link between cerebral blood flow (CBF) alterations and Parkinson's disease (PD) pathogenesis and cognitive decline, the precise pathophysiological mechanisms driving this relationship remain elusive. This study seeks to correlate changes in CBF with regional gene expression to advance mechanistic understanding of the disease.

Methods: CBF group differences were first determined from ASL data in 53 PD and 40 healthy controls (HC) and subsequently correlated with cognitive scores (Dataset 1). A coordinate-based meta-analysis of published literature provided a second set of CBF differences (Dataset 2). Transcriptomic data from the Allen Human Brain Atlas were then correlated with …

Mammography: What Utahns Need To Know, Brie Sparks, Susan R. Madsen

Marketing and Strategy Faculty Publications

Mammography is a critical preventative health tool that enables early detection of breast cancer and improves the likelihood of successful treatment. In Utah, screening behaviors are shaped by access to care, personal perceptions, healthcare experiences, and broader social and structural factors. Understanding both measurable trends and attitudes toward preventative care provides essential context for improving screening rates. Together, these factors influence how, when, and whether Utah women utilize mammography services, ultimately impacting early detection outcomes across the state.

Subunit Composition Of The Katp Channels That Modulate Contractility Of Skeletal Muscle During Fatigue, Rosa Scala, Yuezhou Chen, Berk Mizrak, Gretchen A Meyer, Colin G Nichols

2020-Current year OA Pubs

ATP-sensitive potassium (KATP) channels are among the most expressed ion channels in skeletal muscle sarcolemma. While all KATP subunits can be detected in skeletal muscles, transcripts are enriched for KCNJ11 and ABCC9, suggesting that noncanonical Kir6.2/SUR2A assembly may constitute the majority of sarcolemmal KATP channels, but there has been no systematic dissection of KATP makeup in skeletal muscles. Here, we used a unique collection of murine lines selectively lacking specific channel-forming subunits (knockout, KO), and combined a genetic and pharmacological approach to determine which subunits of KATP channels are functionally relevant for skeletal muscle contraction. Under fatiguing conditions, isometric tetanic …

Single-Nucleotide Rna M6a Mapping In Bovine Preimplantation Development Reveals Site-Specific Regulation Of Rpl12 At Zygotic Genome Activation, Rajan Iyyappan, Yichi Niu, Yang Li, Hao Ming, Kinga Pajdzik, Noah R Rakestraw, Piyush K Jain, Chuan He, Chenghang Zong, Zongliang Jiang

Faculty, Staff and Students Publications

RNA N6-methyladenosine (m6A) is a key regulator of gene expression during early embryogenesis. Using SAC-seq (m6A-selective allyl chemical labeling and sequencing), an antibody-independent m6A profiling method, we generated the first single-nucleotide-resolution m6A map of bovine oocytes and preimplantation embryos. We observed both coordinated and uncoupled relationships between m6A modification and expression of protein-coding and noncoding genes. Integrative analysis of the transcriptome, m6A epitranscriptome, and translatome revealed dynamic m6A remodeling, particularly in ribosomal protein genes. Functional interrogation of a specific m6A site within the RPL12 transcript demonstrated that loss of this modification reduces protein synthesis, disrupts translation-related gene expression, impairs zygotic …

Long-Term Inactivation Mediated By Different Fgf-A Homologues On Heterologously Expressed Nav1.2 Currents, Yenisleidy Lorenzo-Ceballos, Pedro L Martinez-Espinosa, Xiao-Ming Xia, Christopher J Lingle

2020-Current year OA Pubs

A-isoforms of cytosolic growth factor homologous factors (FGF11-14) mediate long-term inactivation (LTI) of voltage-dependent sodium (NaV) channels. LTI is a rapid onset process that is competitive with the fast inactivation (IF) intrinsic to NaV channels, with little or no interconversion between inactivated states. Since recovery from LTI is orders of magnitude slower than recovery from IF, repetitive depolarizations lead to use-dependent accumulation of NaV channels in slow recovery states, thereby limiting NaV availability during trains of action potentials. Of the two or more N-terminal splice variants of the various FGF homologues, LTI specifically arises only from the A-isoform of each …

Developmental Stability Of Task-Rest Neural Efficiency In Youth Using A Threat And Cognitive Control Task, Parmis Khosravi, Julia O. Linke, Anjali D. Poe, Chase Antonacci, Reut Naim, Elise M. Cardinale, Katharina Kircanski, Anderson M. Winkler, Nathan A. Fox, Daniel Samuel Pine, Simona P. Haller

School of Medicine Publications

Behaviors arise from coordinated neural activity across diverse spatial and temporal scales. Prior work has linked better task performance and cognitive functioning to patterns of global network connectivity requiring minimal reconfiguration when switching between task demands. This metric indexing similarity in functional connectivity across task and rest has been termed “neural efficiency.” Here we assess stability of neural efficiency over approximately 3 years in adolescence, specificity across two task-rest combinations and associations with anxiety. At approximately age 16 and/or 19, 95 participants completed a resting state scan alongside a cognitive control and/or threat task. Neural efficiency was quantified as partial …

High-Order Brain Interactions During Ketamine-Induced State Changes: A Functional Marker Of Response In Late-Life Treatment-Resistant Depression?, Krisha Shah, Rubén Herzog, Alan C Swann, Brittany O'Brien, Rahul Balakrishnan, Sanjay J Mathew, Nicholas Murphy

Faculty, Staff and Students Publications

Ketamine is a fast-acting intervention for treatment-resistant depression (TRD), yet only a subset of patients show robust clinical response, and the underlying neural mechanisms remain unclear. High-order interactions (HOI) derived from multivariate information theory provide a framework for examining nonlinear dependencies among brain regions beyond pairwise connectivity. One such metric, the O-information, captures the balance between synergistic and redundant interactions across three or more variables. In this secondary analysis of a randomized, double-blind, midazolam-controlled trial (NCT02556606), we examined EEG-derived HOI in 30 late-life veterans with TRD following a single 40-minute intravenous infusion of ketamine (0.1, 0.25, 0.5 mg/kg; n = …

Ciccotti, Brooks Martino, Frank Cautela, Nathaniel Tchangou, Daniel Kwak, Eric Didomenico, Harrison S. Fellheimer, Christopher C. Dodson, Steven B. Cohen, Michael G. Ciccotti

Rothman Institute Papers

BACKGROUND: Ulnar collateral ligament (UCL) reconstruction (UCLR) is a common procedure for overhead athletes, particularly baseball players sustaining partial or full UCL tears. Palmaris longus (PL) and gracilis (GR) autografts are the most frequently used graft sources, yet limited data compare clinical outcomes in baseball athletes.

PURPOSE: To compare patient-reported outcomes after UCLR with PL versus GR autografts in baseball players.

STUDY DESIGN: Cohort study; Level of evidence, 3.

METHODS: Patients who underwent isolated UCLR with either PL or GR autograft and a minimum of 2 years of follow-up were identified. All reconstructions were performed using the Modified Jobe or …

Tranexamic Acid In High-Risk Shoulder Arthroplasty Patients: Safety Across Thromboembolic, Cardiac, Renal, And Neurologic Risk Profiles, Tarishi Parmar, Akin Adio, Asim Handy, Mohammad Daher, Alec Kellish, Adam Khan, Joseph A. Abboud

Rothman Institute Papers

INTRODUCTION: Tranexamic acid (TXA) effectively reduces blood loss and transfusion requirements in shoulder arthroplasty. However, concerns regarding thromboembolic, neurologic, cardiac, and renal complications have limited its use in medically high-risk patients. This study evaluated temporal trends and the safety of TXA in high-risk patients undergoing total shoulder arthroplasty (TSA).

METHODS: A retrospective cohort study was conducted using TriNetX, identifying patients who underwent shoulder arthroplasty (2012-2025). Patients were stratified by preexisting high-risk conditions, including prior thromboembolism, renal failure, atrial fibrillation, seizure disorders, and visual disturbances. Within each subgroup, patients receiving TXA were propensity score-matched to those who did not. Perioperative TXA …

Aberrant Ciliogenesis Induced By Enhanced Bmp Signaling Causes Heterotopic Ossification, Hiroyuki Yamaguchi, Jianbo Wang, Fangfang Yan, Jiarui Bi, Radbod Darabi, William R. Lagor, Zhongming Zhao, Aris N. Economides, Yuji Mishina, Yoshihiro Komatsu

Faculty, Staff and Student Publications

Bone morphogenetic protein (BMP) signaling is a principal driver of heterotopic ossification (HO), yet how aberrant BMP activity structurally reprograms cellular signaling machinery to develop HO remains unclear. Here, we identify BMP signaling as a direct upstream regulator of ciliogenesis that coordinates a multi-stage, pro-osteochondrogenic signaling relay during HO. Using a conditional gain-of-function BMP mouse model (Acvr1Q207D/+), we demonstrate that enhanced BMP signaling promotes primary cilium biogenesis and axonemal elongation through canonical Smad1/5/9-dependent transcriptional activation of intraflagellar transport (IFT) Ift20, a core component of the IFT machinery. Rather than operating via a singular downstream cascade, these elongated …

School of Mathematical & Statistical Sciences Faculty Publications

Several combination therapies for the early outpatient treatment of COVID-19 were proposed by independent research groups at the onset of the pandemic during 2020 and 2021. In this observational study, we report on the outcomes of an off-label triple combination therapy, consisting of ivermectin, doxycycline, and zinc, with adjunct vitamin C and D3 supplementation, which was used on high-risk COVID-19 patients. These patients refused an initial recommendation to seek inpatient care, despite a high-risk presentation compounded with one or more comorbidities and/or severe hypoxia. Telemedicine was used to administer personalized treatment to patients at home, who did not have access …

Multiplexed Plasmon-Enhanced Lateral Flow Assay For Early Diagnosis Of Acute Kidney Injury, Heng Guo, Yuxiong Liu, Ravi Jada, Ying Liu, Carissa Ng, Aquiles Payte, Jiaying Xu, Connor Malone, Jie Zhao, Kedhareswara Sairam Pasupuleti, Arda Aidan Arikan, Sameer Thadani, Srikanth Singamaneni, Ayse Akcan Arikan, Limei Tian

Faculty, Staff and Students Publications

Early diagnosis of acute kidney injury (AKI) remains a major clinical challenge due to the delayed and insensitive nature of conventional markers such as serum creatinine. Urinary protein biomarkers, including neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (CysC), provide earlier and complementary information on kidney injury, but their clinical translation is limited by the lack of rapid, quantitative, and multiplexed point-of-care (POC) diagnostic tests. Here, we report a multiplexed plasmonic-fluor-based lateral flow assay (p-LFA) that enables sensitive, quantitative, and simultaneous detection of NGAL and CysC. By harnessing ultrabright plasmonic-fluor nanolabels and ratiometric fluorescence analysis, the p-LFA achieves picogram-per-milliliter analytical sensitivity …

A Conserved Mechanism For Dimerization And Activation Of Superfamily 1a Uvrd-Family Helicases, Binh Nguyen, Kacey N Mersch, Ankita Chadda, Eric A Galburt, Timothy M Lohman

2020-Current year OA Pubs

DNA helicases are ATP-dependent motor proteins that catalyze duplex DNA unwinding and are involved in DNA repair, recombination, and replication restart. Prominent members of the non-hexameric SF1A UvrD-family helicases are Escherichia coli UvrD, Rep, Bacillus stearothermophilus PcrA, and Mycobacterium tuberculosis (Mtb) UvrD1. SF1A monomers are processive 3'-to-5' single-stranded DNA translocases but need to be activated to become DNA helicases. One mechanism of activation is dimerization. Whereas Rep, UvrD, and PcrA form non-covalent dimers, the Mtb UvrD1 helicase forms a redox-dependent covalent dimer. Dimerization of Mtb UvrD1 occurs between the same regulatory domain (2B) within each subunit stabilized by a disulfide …

Hypoglossal Nerve Stimulation For Obstructive Sleep Apnea: A Systematic Review And Meta-Analysis On Responder-Based Outcomes And Between-Study Heterogeneity, Clemens Heiser, Marcel Braun, Colin Huntley, Michael Hutz, Thomas Michael Kaffenberger, Maurits Boon

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Background: Hypoglossal nerve stimulation (HNS) is an established surgical therapy for adults with moderate-to-severe obstructive sleep apnea (OSA) who are intolerant to positive airway pressure. Although aggregate response rates of ~70–80% have been reported, substantial variability across clinical settings remains poorly understood. Prior meta-analyses have largely emphasized pooled continuous outcomes, limiting interpretation of responder-based endpoints and drivers of between-study heterogeneity. Methods: A PRISMA-compliant systematic review and meta-analysis was performed. MEDLINE, Embase, and Cochrane CENTRAL were searched from inception through 31 December 2025. Eligible studies enrolled adults with OSA treated with implantable HNS, reported Sher-defined response (≥50% AHI reduction and residual …

Perspective On Lessons Not Learned: From Coley’S Toxins To Microbial Drug Delivery, Guidance For Institutional Review Boards (Irbs), Brian P. Hanley, Alejandro J. Betancourt, Gustavo Gross, Wilbur (Bo) Bowne

School of Medicine Publications

The bacterial and toxin methods of cancer treatment date back 130 years. This paradigm rests on nonspecific bacterial-toxin-generated immunotherapy. This high-risk oncology research is experiencing a renaissance of methods that are among the most effective yet. Glioblastomas and other resistant cancers are the modern touchpoint, because of remission history following sepsis. Spurred by recent research deaths, we discuss protocols IRBs should consider in live bacterial or synthetic immuno-stimulatory trials. Human systemic inflammatory response syndrome immunology is unique due to non-functioning SIGLEC-13 and 17, which control excessive Toll-like receptor 4 (TLR-4) signaling. This is not a technicality like human CD8+/CD4+ T …

Ai-Driven Detection Of Neurodevelopmental Disorder From Emotional Speech Using A Hybrid Cnn–Bilstm–Attention Framework, Nayarah Shabir, Parveen Lehana, Sheema Khan

School of Medicine Publications

Neurodevelopmental disorders (NDDs) are associated with impairments in communication, behavior, and social interaction, making accurate diagnosis clinically challenging. Autism Spectrum Disorder (ASD), a major NDD, often exhibits atypical speech patterns characterized by altered prosody and reduced emotional expressiveness. The study proposes a hybrid dual-path framework for ASD detection from emotional speech using two strategies: PCA–GMM-based acoustic modeling and a CNN–BiLSTM–Attention architecture for spectral–temporal feature learning. The proposed framework captures probabilistic, spectral, and temporal speech characteristics for robust ASD classification. Acoustic analysis demonstrated clear separability between ASD and non-ASD speech, while the deep learning framework achieved stable and reliable performance across …

Transmembrane protein 63B gene (TMEM63B) encodes a mechanosensitive ion channel expressed in alveolar type II epithelial cells, where it mediates stretch-induced surfactant secretion. While heterozygous gain-of-function variants in TMEM63B have been associated with developmental and epileptic encephalopathy, no human disorder has previously been linked to bi-allelic loss-of-function variants. Here, we report five individuals from four unrelated families with childhood interstitial lung disease and bi-allelic predicted loss-of-function variants in TMEM63B. Affected individuals presented with early-onset respiratory distress, chronic hypoxemia, and diffuse parenchymal lung abnormalities on chest imaging. One individual died in infancy, two underwent bilateral lung transplantation, and two require oxygen …

Understanding How Fire Impacts Soil Carbon And Nutrient Cycling: Toward Standardized Reporting Of Fire Metrics For The Integrated Plant-Soil System, Julia B. Gaudinski, Kate Wilkin, Jasquelin Peña, Mary E. Miller, Margaret S. Torn

Michigan Tech Publications

Fire events impact soil carbon (C) and nutrient stocks immediately due to combustion of biomass and organic matter and set up additional post-fire changes to ecosystem inputs and losses. The literature on this topic is expanding rapidly as large and intense wildfires are increasingly affecting communities globally. However, many of these studies do not describe initial post-fire soil conditions adequately or consistently, nor do they link the impacts of fire on C and nutrient cycling to key soil properties and soil inputs, stocks and fluxes. Here we conduct a systematic analysis of 56 review- papers published in 2010 or later …
