Time From Triage To Imaging In Stroke Activations At Children’S Mercy Hospital, Annie Altschul, Marcie Files, Jennifer Flint, Brooke Fridley Phd

Research Days

Background: Stroke affects 2-3 per 100,000 children annually. Timely diagnosis is vital to provide the highest quality care to pediatric stroke patients. Features that contribute to delays in diagnosis of pediatric stroke include complex or subtle signs and symptoms, limited exams in young children, broad differential and frequent stroke mimics, low awareness in the community, and sedating or paralytic medication use in critically ill children. The establishment of stroke activation protocols for children has led to improvements in care for pediatric stroke across numerous centers, expediting time to imaging and treatment.

Objective: We aimed to quantify the time …

Posterior Pharyngeal Flap For The Management Of Velopharyngeal Dysfunction: Comparing Outcomes For Children With 22q11.2 Deletion Syndrome To Those Without, Jay Szekely, Meghan Tracy, Janelle R. Noel-Macdonnell, Jill M. Arganbright

Research Days

Introduction (including objectives): Velopharyngeal dysfunction (VPD) is one of the most common clinical features of 22q11.2 deletion syndrome (22q11.2DS) and often requires surgical intervention; due to the multifactorial nature of VPD, these patients present unique and often complex surgical challenges. Prior studies have generally demonstrated poorer speech outcomes postoperatively in children with 22q11.2DS. The posterior pharyngeal flap (PPF) is often considered first-line surgical choice for correction of VPD in children with 22q11.2DS. The aim of this study is to compare PPF outcomes for children with 22q11.2DS to those without.

Methods: Retrospective review for pediatric patients diagnosed with VPI who underwent …

Background/Objectives: We aimed to discover genes with bimodal expression linked to patient outcomes, to reveal underlying oncogenotypes and identify new therapeutic insights in lung adenocarcinoma (LUAD).

Methods: We performed meta-analysis to screen LUAD datasets for prognostic genes with bimodal expression patterns. Kynureninase (KYNU), a key enzyme in tryptophan catabolism, emerged as a top candidate. We then examined its relationship with LUAD mutations, metabolic alterations, immune microenvironment states, and expression patterns in human and mouse models using bulk and single-cell transcriptomics, metabolomics, and preclinical model datasets. Pan-cancer prognostic associations were also assessed.

Results: Model-based clustering of KYNU expression outperformed median-based dichotomization …

Tacrolimus is the most commonly used immunosuppression drug after solid organ transplantation; however, its dosing is challenging due to substantial inter-individual variability, often resulting in blood levels that deviate from the target therapeutic range. We explored whether a dynamically customized, phenotypic-outcome-guided drug dosing method could improve maintenance of drug trough levels within pre-determined target ranges, focusing on tacrolimus immediately after liver transplantation. This single-center, partially blinded, completed clinical trial involved 62 adults undergoing liver transplantation, block randomized into parallel groups: standard-of-care (SOC) clinician-determined or Phenotypic Personalized Medicine (PPM)-guided tacrolimus dosing. The primary outcome was percentage of post-transplant days with large …

Shilla Growth Guidance System (Sggs) Instrumentation With Pelvic Foundation (Sggs) For Severe Neuromuscular Spine Deformity. Does It Work?, Hannah Geoffroy, Richard Schwend

Research Days

This study evaluates the use of the Shilla Growth Guidance System (SGGS) with a pelvic foundation for treating severe neuromuscular scoliosis in young children. The primary outcomes include revision surgery and complication rates. In a 21-patient cohort (mean age 5.3 years, follow-up 10 years), 57% required only one surgery, while 43% needed revisions. The complication rate was 38%, with a 29% deep infection rate. The procedure improved spinal alignment and growth but carried significant risks. SGGS with pelvic fixation may reduce the need for repeated surgeries in this complex patient population.

Background

Pre-Exposure Prophylaxis (PrEP) significantly reduces the risk of contracting HIV:

  • Reduces risk from sexual contact by 99%
  • Reduces risk from injection drug use by at least 74%

Despite its effectiveness, PrEP is underutilized in the USA.

  • In 2019, an estimated 224,000 Americans received a prescription for PrEP despite 1.1 million people having indications for PrEP.
  • Lack of provider knowledge surrounding PrEP clinical guidelines is a common reason for underutilization.

Sickle cell disease (SCD) affects millions of individuals worldwide, and is characterized by both acute, episodic pain and chronic, persistent pain. Despite the significant burden of the disease, clinicians continue to face significant challenges in treating SCD pain due to variability in pain experiences. The objectives of this study were (1) to identify distinct pain subgroups based on demographic and biopsychosocial characteristics and (2) to evaluate the relationship between the subgroups and pain impact - a SCD-disease specific measure of pain interference. To achieve these objectives, we performed a hierarchical cluster analysis on a cross-sectional sample of adults with SCD …

Faculty, Staff and Students Publications

Maintaining a balance of inorganic phosphate (Pi) is vital for cellular functionality. Proper phosphate levels are managed through Pi import and export; and the processes governing Pi export remain the least understood. Xenotropic and Polytropic retrovirus Receptor 1 (XPR1) has been identified as the only known Pi export protein in mammals. In this study, we introduce the cryogenic electron microscopy structure of human XPR1 (hXPR1), unveiling a structural arrangement distinct from that of any known ion transporter. Our structural results suggest that hXPR1 may operate as an ion channel, a hypothesis supported by patch clamp recordings revealing hXPR1's voltage- and …

Intertrial Coherence As A Measure Of Synchrony In Ocular Vestibular Evoked Myogenic Potentials And The Effect Of Gaze Angle, Sydney Brown May 2025

Intertrial Coherence As A Measure Of Synchrony In Ocular Vestibular Evoked Myogenic Potentials And The Effect Of Gaze Angle, Sydney Brown

Dissertations, 2020-current

Ocular vestibular evoked myogenic potentials (oVEMPs) are produced by highly synchronous bursts of extraocular muscle activity in response to stimuli. These responses reflect utricular function and can be recorded using surface electromyography electrodes. Traditional analysis of oVEMPs is limited to time-domain waveform measurements, such as amplitude and latency of response peaks. Objective synchrony-based measures have not yet been applied to the analysis of oVEMPs, particularly in the comparison of synchrony across gaze angles. We followed the new time-frequency method of analysis developed by Clinard et al. (2022) that was successfully applied to cervical VEMPs to quantify response synchrony. Air-conducted oVEMPs …

Lung cancer, the leading cause of cancer mortality, exhibits diverse histological subtypes and genetic complexities. Numerous preclinical mouse models have been developed to study lung cancer, but data from these models are disparate, siloed, and difficult to compare in a centralized fashion. In this study, we established the Lung Cancer Autochthonous Model Gene Expression Database (LCAMGDB), an extensive repository of 1,354 samples from 77 transcriptomic datasets covering 974 samples from genetically engineered mouse models (GEMMs), 368 samples from carcinogen-induced models, and 12 samples from a spontaneous model. Meticulous curation and collaboration with data depositors produced a robust and comprehensive database, …

Recently discovered constituents of the brain waves—the oscillons—provide a high-resolution representation of the extracellular field dynamics. Here, we study the most robust, highest-amplitude oscillons recorded in actively behaving male rats, which underlie the traditional θ-waves. The resemblances between θ-oscillons and the conventional θ-waves are manifested primarily at the ballpark level—mean frequencies, mean amplitudes, and bandwidths. In addition, both hippocampal and cortical oscillons exhibit a number of intricate, behavior-attuned, transient properties that suggest a new vantage point for understanding the θ-rhythms’ structure, origins and functions. In particular, we demonstrate that oscillons are frequency-modulated waves, with speed-controlled …

Candida is one of the most frequent causes of bloodstream infections, and our first line of defense against these invasive infections is the innate immune system. The early immune response is critical in controlling Candida albicans infection, but C. albicans has several strategies to evade host immune attack. Phagocytosis of C. albicans blocks hyphal growth, limiting host damage and virulence, but how C. albicans limits early recruitment and phagocytosis in vertebrate infection is poorly understood. To study innate immune evasion by intravital imaging, we utilized the transparent larval zebrafish infection model to screen 131 C. albicans mutants for altered …

BACKGROUND: Spirometry is a widely used pulmonary function test that assesses lung function by examining airflow and capacity. Spirometry measurements assist in the diagnosis, severity classification, and management of asthma, and can affect one’s eligibility into various events (e.g., clinical trials, high-risk jobs, sports). Reference equations are used to establish predicted values to account for biological variables such as age, sex, and height; however past clinical guidelines recommended utilizing race-correction. The incorporation of race may negatively impact people of color due to misrepresentation of one's lung function, consequently impacting future medical management. OBJECTIVES: To characterize differences in spirometry values across …

In drug-resistant focal epilepsy, planning surgical resection can involve presurgical intracranial EEG (iEEG) recordings to detect seizures and other iEEG patterns to improve postsurgical seizure outcome. We hypothesized that resection of tissue generating interictal high-frequency oscillations (HFOs, 80-500 Hz) in the iEEG predicts surgical outcome. In eight international epilepsy centres, iEEG was recorded during the presurgical evaluation of patients. The patients were of all ages, had epilepsy of all types, and underwent surgical resection of a single focus aiming at seizure freedom. In a prospective analysis, we applied a fully automated definition of HFO that was independent of the dataset. …

Children represent a highly complex and variable population for treatment, including interindividual differences in drug dose-exposure. Midazolam has been used as a sedative for hospitalized children on- and off-label; however, factors affecting interindividual variability (IIV) in observed clearance for this population are not fully understood and can result in extreme under- or overexposure. Obesity has been described as a significant influence on midazolam in adolescents, which could potentially alter drug exposure. The goal of this study was to use two modeling strategies to evaluate dose-exposure of midazolam in children with and without obesity. Population pharmacokinetic modeling assessed whether measures of …

The conjugation of small ubiquitin-like modifiers (SUMO) to target proteins, known as SUMOylation, plays a crucial role in regulating protein homeostasis, activity, interaction with other proteins, and subcellular localization. Loss of SUMOylation in nongrowing oocytes by conditional deletion of the E2 SUMO conjugating enzyme, Ube2i, at the primordial follicle stage leads to female sterility due to complex changes in oocyte development, including altered folliculogenesis, defective meiotic progression, and premature loss of the ovarian reserve. In this study, proteomics was used to compare control and Ube2i conditional knockout ovaries during the first wave of folliculogenesis to identify key differences that may …

Optimal Diagnostic Strategies For Concussion-Related Vision Disorders: A Review, Iniya K. Adhan, Kammi B. Gunton

Wills Eye Hospital Papers

Concussions are a mild form of traumatic brain injury (TBI) that is typically self-limited and transient with a high prevalence within our communities. Due to the vast visual network interconnectivity, visual symptoms secondary to a concussion occur about 90% of the time. A gold standard to confirm concussion acutely has not been well established. Visual function testing based on symptoms remains the standard of care in off-site evaluation for diagnosis of oculomotor dysfunction. This review covers the current diagnostic strategies for vision based disorders post-concussion for sideline testing, off-site testing, and research driven testing.

The progesterone receptor (PR) is a steroid-responsive nuclear receptor with two isoforms: PR-A and PR-B. Disruption of PR-A:PR-B signaling is associated with breast cancer through interactions with oncogenic co-regulatory proteins (CoRs). However, molecular details of isoform-specific PR-CoR interactions remain poorly understood. Using structural mass spectrometry, we investigate the sequential binding mechanism of purified full-length PR and intact CoRs, steroid receptor coactivator 3 (SRC3) and p300, as complexes on target DNA. Our findings reveal selective CoR NR-box binding by PR and unique interaction surfaces between PR and CoRs during complex assembly, providing a structural basis for CoR sequential binding on PR. …

Narrative persuasion has been widely used in health communication campaigns and persuasive message design. However, several meta-analyses showed that the relative effectiveness of narratives in promoting behavior change was not consistently observed in the existing literature. With the goal of exploring boundary conditions of narrative effects, this study investigates the interaction effects of narrative persuasion and stages of change on promoting behavior change in the context of encouraging parents to vaccinate their children against human papillomavirus (HPV). Findings from an online experiment (N = 593) showed that non-narrative messages were more effective in bolstering behavioral intention than narrative messages among …
