Understanding Atomoxetine Exposure Variability In Children And Adolescents With Adhd Through Population Pharmacokinetics., Kevin V. Tobin, Addison M. Pritchett Ms, J Steven Leeder, Joga Gobburu, Allison Dunn

Manuscripts, Articles, Book Chapters and Other Papers

Atomoxetine, a selective norepinephrine reuptake inhibitor, is a nonstimulant alternative to treat attention-deficit/hyperactivity disorder in children and adolescents. Atomoxetine exposure is highly variable due to cytochrome P450 polymorphism; however, the impact of these genetic variations has not been adequately characterized in the pediatric population. A population pharmacokinetic (PK) model was developed to evaluate steady-state atomoxetine exposures after oral administration in a large, heterogeneous population of children and adolescents with different metabolic phenotypes. Due to the highly variable and complex absorption between subjects and occasions, a two-stage approach was implemented, treating each participant/occasion as a separate individual. First, the individual atomoxetine …

OBJECTIVE: Many young children with isolated skull fractures are referred to child protective services (CPS) despite being assessed to have a low likelihood of abuse. We sought to identify factors associated with CPS referrals in this population and to quantify hospital-level variation.

METHODS: We performed a multicenter retrospective cross-sectional study of children < 2 years with skull fractures with or without a small underlying intracranial hemorrhage (ICH) and no additional injuries undergoing a child abuse pediatrics (CAP) subspecialty evaluation. We explored associations between demographic factors, clinical characteristics, psychosocial risk factors, and hospital site with CPS referral status. We performed multivariable logistic regression, adjusting for transfer status and all significant covariates from unadjusted analyses. We utilized marginal standardization to calculate the estimated probability of CPS referrals at each site, adjusting for all factors in the final model.

RESULTS: Of 528 children, 303 (57.4%) were referred to CPS, with 86.5% referred before CAP consultation. In multivariable logistic regression, presence of psychosocial risk factors (OR 4.00; 95% CI 2.25, 7.11), in-person CAP consult (OR 3.93; 1.61, 9.62), inflicted or no trauma history provided (OR 6.15; 3.30, 11.45), …

Confessions In Cases Of Child Physical Abuse-A Capnet Study., Margaret R. Russell, Antoinette L. Laskey, Henry T. Puls, Suzanne P. Starling, Joanne N. Wood, Daniel M. Lindberg, Nancy S.

OBJECTIVE: Prior research on confessions of physical abuse (PA) has explored mechanisms of injury. Little is known about conditions supporting a confession of abuse or how confessions may influence case outcomes.

METHODS: This cross-sectional study of suspected PA in children aged < 10 years at 10 centers participating in CAPNET, a multicenter child PA research network, included children with in-person Child Abuse Pediatrics (CAP) consultations between February 2021 and December 2022 and excluded children without injury. Our focus was a confession of inflicted injury known to the CAP during clinical involvement. We compared child and clinical characteristics, out-of-home (OOH) placements, and arrests between cases with and without confessions. Multivariable models using generalized estimating equations (GEE) produced adjusted predicted probabilities (APP) clustering by CAPNET site.

RESULTS: Confessions were known to CAPs in 115/4297 (2.7%) cases, with significant site variability. In a multivariable GEE model, confessions were more likely in cases with injuries with high specificity for abuse (APP 6.0% vs 1.6%, P < .001), near-fatality (APP 5.6% vs 2.3%, P < .001), and older children (APP 4.8% vs 2.5%, P = .025). OOH placements and arrests were more common in cases with confessions. CAP awareness of confessions, OOH placements, and arrests did not follow racial or ethnic patterns seen in the US child welfare system. Lower socioeconomic status was associated with OOH placements and arrests but not with CAP awareness of confessions.

CONCLUSIONS: Our findings highlight differences in case characteristics and outcomes where a confession is known to the CAP and raise questions about …

Protocol For Non-Invasive Assessment Of Skeletal Muscle Structure And Function In Adolescents With Single Ventricle Heart Disease: A Cross-Sectional, Case-Control Study., Tyler A. Fick, Trent J. Herda, Emily Cramer, David A. White, Daniel Forsha

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Congenital heart disease (CHD) is the most common congenital malformation, and the most severe type, single ventricle (SV) heart disease, requires the Fontan surgical palliation. Fontan palliation minimizes hypoxemia and volume overload by separating systemic and pulmonary circulations, resulting in the absence of a sub-pulmonary pump. Skeletal muscle health may have a greater relative contribution to overall functional capacity of those with SV physiology, via the skeletal muscle (SkM) pump mechanism and oxidative capacity. The purpose of this study is to comprehensively evaluate multiple domains of SkM in this population compared to those with normal cardiac anatomy.

METHODS: Forty …

Evaluating Human Rod Photoreceptor Function Using Pixelwise Intensity-Based Optoretinography, Gao Yang, Mina Gaffney, Robert F. Cooper

Biomedical Engineering Faculty Research and Publications

Purpose: More than 50 inherited retinal diseases are known, with rod photoreceptor functional loss serving as an early indicator in nearly half of them. The “optoretinogram” is a relatively new assay that detects optical changes in cells in response to stimuli. This tool has excellent potential for providing insights into the earliest functional changes of rod photoreceptors, with the potential to assist in the early detection, monitoring, and treatment of retinal diseases.

Methods: In this work, we obtained intensity-based optoretinograms (iORGs) from rod photoreceptors using an adaptive optics scanning laser ophthalmoscope. We explore the necessity of both individual rod identification …

Herding Cats: The Behavioral Foundations Of Successful Multi-Sector Partnerships, Paul B. Olsen

School of Public Service Theses & Dissertations

Multi-sector partnerships (MSPs) are problem-solving groups composed of government agencies, nonprofit organizations, private firms, community groups, and individuals. These partnerships have often struggled to achieve consistent success, with performance rates estimated at 30%–50%, largely because MSPs are tailored to the specific interests, resources, and implementation contexts of the constellation of stakeholders involved in each project. This situation raised important questions regarding how MSP performance can be predicted and whether the likelihood of success can be enhanced during the early planning stages of partnership formation.

Early Parenting Stress And Later Abuse Risk: Dyadic Mediation By Maternal And Paternal Negative Attributions, Jewelian N. Fairchild

Psychology Theses & Dissertations

Parenting stress and negative parental attributions are key contributors to child abuse risk. Early parenting stress may increase a parent’s risk of negatively appraising their child’s behaviors, which, in turn, may influence their likelihood of harsh or abusive parenting. Grounded in Social Information Processing (SIP) Theory, the present study explored how these processes evolve over time and differ between mothers and fathers. Specifically, this study investigated whether parental negative attributions mediated the relationship between early parenting stress and later abuse risk. A sample of 203 first-time mothers and 151 of their male partners were recruited prenatally as part of a …

Okra is increasingly recognized as a climate-resilient crop within diversified agroecological systems; however, an integrated synthesis of its biophysical, agronomic, and socioeconomic dimensions is lacking. This review consolidates the current knowledge on okra physiology, production ecology, and value chains, with a focus on climate resilience under heat, drought, salinity, pest, and disease pressures. Evidence across regions demonstrates that agroecological practices such as crop diversification, mulching, conservation tillage, integrated pest management, and the use of organic and biological inputs consistently improve soil health, stabilize yields under climatic stress, and reduce dependence on external inputs, although with trade-offs in labor demand and …

A Novel Nudt16-Based Strategy For Producing Defined Phosphoribosylated Substrates To Study Nampt Antiviral Activity Against Hsv-1, Steph Nivaggioli

Bioengineering Master's Theses

Herpes simplex virus (HSV) is a highly prevalent human pathogen whose symptoms are characterized by the formation of painful blisters and ulcers. There are two major families of HSV: HSV-1, primarily transmitted through oral contact, and HSV-2, predominantly spread through sexual contact. Periodic reactivation of the virus enables continued transmission and recurrent disease. Antiviral drugs that suppress viral replication are available to the public; however, no curative therapy exists.

Recent studies suggest that HSV reprograms host cellular metabolism to support its replication. Notably, this includes the manipulation of nicotinamide adenine dinucleotide (NAD⁺) homeostasis. Under standard physiological conditions, NAD⁺ is consumed …

Quality Of Antenatal And Delivery Care And Postnatal Care Use: A Multi-Country Observational Study Of 400,000 Births, Jan E. Cooper, Hwa-Young Lee, Katherine Wright, Prashant Jaryan, Margaret E. Kruk

2020-Current year OA Pubs

BACKGROUND: Postnatal care (PNC) plays a crucial role in averting newborn mortality, yet its use remains low, particularly in regions with the highest mortality. While demographic and social determinants of PNC use have been well studied and have informed current strategies focused on changing care-seeking behaviors, the stagnating decline in neonatal mortality highlights the need for upstream and system-wide approaches to increase PNC uptake. Limited evidence exists to guide system-level reforms; therefore, we investigated whether health systems that ensure high-quality perinatal care are associated with increased use of PNC.

METHODS AND FINDINGS: We performed a cross-sectional observational study using Demographic …

Detailed Single-Cell Mapping Of The Transcriptional Response To A Virus Infection Driven By Copy-Back Viral Genomes, Yanling Yang, Emna Achouri, Munyaradzi Tambo, Carolina B. López

2020-Current year OA Pubs

The antiviral response to several clinically significant viruses, including respiratory syncytial virus and parainfluenza virus, is driven by copy-back viral genomes (cbVGs) generated during virus replication. However, the broader impact of cbVGs on the functional states of host cells remains undefined. Here, we developed a single-cell RNA-sequencing and computational framework to map cbVG-driven host responses during Sendai virus infection. Unsupervised profiling identified distinct transcriptional states throughout the course of infection, highlighting a shift from early antiviral signaling to later inflammatory and remodeling programs. Stratifying infected cells by cbVG status demonstrated that cbVG-positive cells initiate interferon and chemokine programs, which later …

Introduction Wildlife health is integral to functioning, complex ecosystems [1], directly and indirectly influencing the health of people, animals, plants, and the environment [2–4]. Healthy wildlife populations are essential for ecosystem services and are at the heart of the One Health approach [3,4], which aims to sustainably balance and optimize the health of people, animals, and ecosystems through multisectoral and transdisciplinary collaboration [5]. Despite its importance, wildlife health initiatives often operate in silos, limiting capacity to address transboundary threats such as emerging diseases, pollution, and environmental changes. Anthropogenic changes, including habitat loss, degradation, fragmentation, and unsustainable harvesting, exacerbate wildlife health …

Relational Practices Underpinning Person-Centred Care In Long-Term Residential Care Settings., Gary Hodge, Sam Ebden, Susie Pearce

X-Linked Cancer-Associated Polypeptide (Xcp) From Lncrna1456 Modulates Phf8 Histone Demethylase Activity To Regulate The Epigenome, Gene Expression, And Cellular Pathways In Breast Cancer, Shrikanth S. Gadad, Cristel V. Camacho, Xuan Gong, Micah Thornton, Venkat S. Malladi, Anusha Nagari, Aishwarya Sundaresan, Tulip Nandu, Sneh Koul, Yan Peng, W. Lee Kraus

School of Medicine Publications

Recent studies have demonstrated that a subset of long “noncoding” RNAs (lncRNAs) produce functional polypeptides and proteins. In this study, we discovered a 132 amino acid protein in human breast cancer cells named XCP (X-linked Cancer-associated Polypeptide), which is encoded by lncRNA1456 (a.k.a. RHOXF1P3), a transcript previously thought to be noncoding. lncRNA1456 is a pancreas- and testis-specific RNA whose gene is located on chromosome X. We found that the expression of lncRNA1456 and XCP is highly upregulated in the luminal A, luminal B, and HER2 molecular subtypes of breast cancer. XCP modulates both estrogen-dependent and estrogen-independent growth of breast …

Does Ai-Driven Empathy Work In Healthcare Marketing? The Impact Of Cognitive And Affective Empathy In Chatbots And The Moderating Role Of Illness Type, Jee Won Kim, Yeonsoo Kim, Jino Chung

Asia Marketing Journal

Recognizing the growing potential of AI-generated chatbots in healthcare and healthcare marketing, this study investigates how different types of chatbot-expressed empathy influence user responses in stigmatized versus non-stigmatized health contexts. Perceived authenticity is introduced as a key mediator. Drawing on Mind Perception Theory, a 3 (empathy: none, cognitive, affective) × 2 (illness type: stigmatized, non-stigmatized) online experiment was conducted. The findings show that affective empathy reduced perceived authenticity, which subsequently decreased user satisfaction, perceived understanding, reuse intention, and follow intention. These indirect effects varied by illness type: in stigmatized contexts, non-empathetic communication was viewed most favorably, whereas in non-stigmatized contexts, …
