Therefore, the National Kidney Foundation organized a multidisciplinary working group, including people with CKD and family care partners, to develop recommendations to improve vaccination rates, vaccination effectiveness, and health care for the CKD population. A modified Delphi process was used to achieve consensus on the recommendations. Recommendations on vaccination in CKD patients were organized into these categories: (1) patient preferences; (2) assessing the vaccination status of patients with CKD; (3) assessing vaccine response in patients with CKD; (4) vaccination of immunocompromised patients; (5) vaccination in posttransplant patients; (6) …

Exploring Adolescent Hearing Aid Usage And Appearance Of Psychiatric Symptoms In Adolescents Using Hearql-28 Surveys, Courtney J. Austin, Dylan Chan

MEDI 9331 Scholarly Activities Clinical Years

Approximately 2% of DHH people in need of mental health services actually receive these services. Among pediatric hearing loss populations, co-occurring cognitive and physical impairments are risk factors for poor mental health status. Due to language barriers and isolation, more children with hearing loss do not have access to mental health services. Cochlear implants have been shown to improve mental health status among the DHH population. Current literature focuses on the mental health status of children with cochlear implants, with little focus on hearing aid users. Using HEAR28 data and surveys, we can quantify the incidence of psychiatric symptoms among …

Prospective Validation Of Selective Serotonin Reuptake Inhibitor Pharmacokinetic Models For Precision Dosing In Children And Adolescents, Ethan A. Poweleit, Whitney Sparks Ms, Catherine Koertje, Addison Pritchett Ms, Gail Robertson, Lindsey Malloy-Walton, Stephani Stancil, Jeffrey R. Strawn, Alexa L. Pagano, Kathryn Kyler, Jonathan B. Wagner, Brandon Retke, Paul C. Toren, J Steven Leeder Pharmd, Phd, Laura B. Ramsey

Posters

Background: Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to children and adolescents with anxiety and depression. However, their clinical use is complicated by marked interindividual variability in exposure, which contributes to differences in treatment response and side effects. Further, SSRIs are commonly dosed using a trial-and-error approach. Model-informed precision dosing could improve treatment outcomes, yet existing SSRI population pharmacokinetic (PK) models have not been prospectively validated and may not generalize to pediatric patients. This study aims to evaluate how accurately these models predict exposure for three SSRIs—escitalopram (ESC), sertraline (SRT), and fluoxetine (FLX)—and refine them to develop tools for …

Comparison Of Agar-Based Methodologies To Broth Disc Elution For The Detection Of Aztreonam Susceptibility In The Presence Of Ceftazidime-Avibactam, Teslin Sandstrom, Andra Banete, Alice Kanyua, Kevin Davis, Susan Poutanen

Pathology, East Africa

The combination of aztreonam and ceftazidime-avibactam is a proven treatment option for infections caused by metallo-beta-lactamase (MBL)-expressing gram-negative organisms. Restoration of aztreonam susceptibility in the presence of ceftazidime-avibactam can be determined using the Clinical and Laboratory Standards Institute (CLSI)’s broth disc elution (BDE) method; however, the high manual workload and significant material footprint of this assay make it difficult to implement in a high-throughput clinical microbiology lab. This study evaluates two agar-based methods for the detection of susceptibility to the combination of aztreonam and ceftazidime-avibactam, using BDE as the comparator methodology. Resistant Enterobacterales, Pseudomonas aeruginosa, Stenotrophomonas maltophilia, and Acinetobacter spp. …

Faculty, Staff and Students Publications

The relationship between misophonia and sleep-related problems (SRPs) in youth is underexplored. This paucity of research is concerning because SRPs might be elevated among youth with misophonia. If left untreated, SRPs can contribute to long-term health consequences. Thus, in this study we examined the link between misophonia and SRPs in youth aged 8 to 17. In this study, we compared SRPs in 102 children and adolescents with clinically significant misophonia to SRPs in a normative youth sample and a sample of 94 youth with anxiety disorders. We also examined the extent to which SRPs were associated with misophonia severity. Approximately …

Faculty, Staff and Students Publications

PURPOSE: Rural Veterans with serious mental illness (SMI) encounter significant barriers to accessing mental health care, related to SMI symptoms and rurality. A 2023 Government Accountability Office report found that rural Veterans used Veterans Health Administration (VHA) intensive mental health care for SMI less than urban Veterans relative to their population distributions. Our purpose was to deepen understanding of rural-urban differences in use of VHA mental health care among Veterans with SMI.

METHODS: Using VHA databases, we conducted a retrospective cohort analysis of 387,477 Veterans diagnosed with SMI, examining rurality as a predictor of intensive care for SMI and other …

Simulation-Free Spine Palliative Radiotherapy Enabled By Ai-Adapted Diagnostic Ct, Yiding Han, Alexander Nicola Hanania, Zaid Ali Siddiqui, Vincent Ugarte, Boran Zhou, Abdallah S R Mohamed, Piyush Pathak, Daniel Allen Hamstra, Baozhou Sun

Faculty, Staff and Students Publications

Background: Radiotherapy planning traditionally requires a dedicated simulation CT (sCT), which can introduce delays in initiating treatment. This is particularly impactful in spinal palliative care, where timely treatment is often important for symptom control and prevention of neurological deterioration. Although diagnostic CT (dCT) is frequently available earlier in the workflow, it can lead to geometric and dosimetric inaccuracies when used directly for treatment planning due to discrepancies in patient positioning, vertebral alignment, and table curvature.

Purpose: To develop and evaluate an AI-based method that transforms dCT into a simulation-equivalent planning CT (AI-pCT), enabling a clinically feasible simulation-free workflow for spinal …
