Comparing Children’S Engagement In Storybook Reading With And Without Access To Aac With A Literacy Supportive Feature, Brooke Zimmerman

Graduate Theses and Dissertations

Purpose: This thesis evaluates the effects of comparing children’s engagement in storybook reading with and without access to high-tech augmentative and alternative communication (AAC) with a literacy supportive feature. Literacy skills are a fundamental cornerstone for engagement in the lives of young children. Among these skills, the ability to decode words, or phonetically sound them out, plays a pivotal role in the acquisition of literacy. Proficiency in literacy also broadens the communication capabilities of individuals with developmental disabilities who rely on augmentative and alternative communication (AAC) methods. However, existing AAC technologies currently fall short in adequately strengthening literacy development, particularly …

Optimal therapeutic approaches for advanced Langerhans cell histiocytosis (LCH) are not known. We assessed the safety and efficacy of combined chemotherapy with MAPK pathway inhibition in 10 patients with refractory systemic disease and/or LCH-associated neurodegeneration. Overall response rate was 9/10 (90%) for the entire cohort: 5/5 (100%) for patients with systemic disease and 6/7 (86%) for patients with central nervous system disease. BRAFV600E+ peripheral blood fraction decreased in 5/6 (83%). Toxicities included fever, skin rash, myalgias, neuropathy, cytopenias and hypocalcaemia. Prospective trials are required to optimize combination strategies, determine potential to achieve cure and compare outcomes to chemotherapy or MAPK …

Hypertension affects more than one billion people worldwide. Here we identify 113 novel loci, reporting a total of 2,103 independent genetic signals (P < 5 × 10-8) from the largest single-stage blood pressure (BP) genome-wide association study to date (n = 1,028,980 European individuals). These associations explain more than 60% of single nucleotide polymorphism-based BP heritability. Comparing top versus bottom deciles of polygenic risk scores (PRSs) reveals clinically meaningful differences in BP (16.9 mmHg systolic BP, 95% CI, 15.5-18.2 mmHg, P = 2.22 × 10-126) and more than a sevenfold higher odds of hypertension risk (odds ratio, 7.33; 95% CI, 5.54-9.70; P = 4.13 × 10-44) in an independent dataset. Adding PRS into hypertension-prediction models increased the area under the receiver operating characteristic curve (AUROC) from 0.791 (95% CI, 0.781-0.801) to 0.826 (95% CI, 0.817-0.836, ∆AUROC, 0.035, P = 1.98 × 10-34). We compare the 2,103 loci results in non-European ancestries and show significant PRS associations in a large African-American sample. Secondary analyses implicate 500 genes previously unreported for BP. Our study highlights the role of increasingly large genomic studies for precision health research.

Bile acids (BAs) are pleiotropic regulators of metabolism. Elevated levels of hepatic and circulating BAs improve energy metabolism in peripheral organs, but the precise mechanisms underlying the metabolic benefits and harm still need to be fully understood. In the current study, we identified orosomucoid 2 (ORM2) as a liver-secreted hormone (i.e., hepatokine) induced by BAs and investigated its role in BA-induced metabolic improvements in mouse models of diet-induced obesity. Contrary to our expectation, under a high-fat diet (HFD), our Orm2 knockout (Orm2-KO) exhibited a lean phenotype compared with C57BL/6J control, partly due to the increased energy expenditure. However, when challenged …

Type 2 Airway Inflammation In Copd, Francesca Polverino, Don D Sin

Faculty, Staff and Students Publications

Globally, nearly 400 million persons have COPD, and COPD is one of the leading causes of hospitalisation and mortality across the world. While it has been long-recognised that COPD is an inflammatory lung disease, dissimilar to asthma, type 2 inflammation was thought to play a minor role. However, recent studies suggest that in approximately one third of patients with COPD, type 2 inflammation may be an important driver of disease and a potential therapeutic target. Importantly, the immune cells and molecules involved in COPD-related type 2 immunity may be significantly different from those observed in severe asthma. Here, we identify …

Isothermal nucleic acid amplification methods have many advantages for use at the point of care. However, there is a lack of multiplexed isothermal amplification tests to detect multiple targets in a single reaction, which would be valuable for many diseases, such as infection with high-risk human papillomavirus (hrHPV). In this study, we developed a multiplexed loop-mediated isothermal amplification (LAMP) reaction to detect the three most common hrHPV types that cause cervical cancer (HPV16, HPV18, and HPV45) and a cellular control for sample adequacy. First, we characterized the assay limit of detection (LOD) in a real-time reaction with fluorescence readout; after …

Doses to brain structures were compared between treatment modalities. Linear mixed-effects models were used to create models of global IQ and cognitive domain scores.

Results: The mean dose and dose to …

Illness Perceptions And Health-Promoting Behaviors: The Buffering Role Of Resilience In Adults With Congenital Heart Disease, Taylor Rose Eldridge

Electronic Theses and Dissertations

Congenital heart defects (CHD) are one of the most prevalent genetic abnormalities, impacting the lives of millions of children, teens, and young adults. Conservative diagnoses estimate that 2.4 million children and adults are living with CHD in the United States (Gilboa et al., 2016). CHD requires consistent cardiac support with multiple surgeries and hospitalizations expected throughout the lifetime, which significantly impacts psychological health. Specifically, patients present with a host of extra-cardiac conditions that impact their quality of life. With advancements in medical technology, mortality rates continue to improve for this population; however, individuals face a number of consequences that impact …

Purpose: Resistance to endocrine therapy (ET) and CDK4/6 inhibitors (CDK4/6i) is a clinical challenge in estrogen receptor (ER)-positive (ER+) breast cancer. Cyclin-dependent kinase 7 (CDK7) is a candidate target in endocrine-resistant ER+ breast cancer models and selective CDK7 inhibitors (CDK7i) are in clinical development for the treatment of ER+ breast cancer. Nonetheless, the precise mechanisms responsible for the activity of CDK7i in ER+ breast cancer remain elusive. Herein, we sought to unravel these mechanisms.

Experimental design: We conducted multi-omic analyses in ER+ breast cancer models in vitro and in vivo, including models with different genetic backgrounds. We also performed genome-wide …

Impact Of Obesity And Age On Mouse Corneal Innervation At The Epithelial-Stromal Interface, Justin A Courson, Rolando E Rumbaut, Alan R Burns

Faculty, Staff and Students Publications

PURPOSE: The corneal epithelium is the most highly innervated structure in the body. Previously, we reported a novel event whereby stromal axons fuse with basal epithelial cells, limiting nerve penetration into the epithelium. Although corneal-epithelial nerves undergo changes in sensitivity and distribution throughout life and in response to an obesogenic diet, it is unknown if neuronal-epithelial cell fusion is altered. Here, we sought to determine if neuronal-epithelial cell fusion frequency correlates with obesogenic diet consumption and age.

METHODS: Corneas were collected from C57BL/6 mice and evaluated for neuronal-epithelial cell fusion frequency using serial block-face scanning electron microscopy. To assess the …

Sialic Acid-Siglec-E Interactions Regulate The Response Of Neonatal Macrophages To Group B Streptococcus, Sean J Lund, Pamela G B Del Rosario, Asami Honda, Kaitlin J Caoili, Marten A Hoeksema, Victor Nizet, Kathryn A Patras, Lawrence S Prince

Faculty, Staff and Students Publications

The mammalian Siglec receptor sialoadhesin (Siglec1, CD169) confers innate immunity against the encapsulated pathogen group B Streptococcus (GBS). Newborn lung macrophages have lower expression levels of sialoadhesin at birth compared with the postnatal period, increasing their susceptibility to GBS infection. In this study, we investigate the mechanisms regulating sialoadhesin expression in the newborn mouse lung. In both neonatal and adult mice, GBS lung infection reduced Siglec1 expression, potentially delaying acquisition of immunity in neonates. Suppression of Siglec1 expression required interactions between sialic acid on the GBS capsule and the inhibitory host receptor Siglec-E. The Siglec1 gene contains multiple STAT binding …

Evaluation Of Wogonin And Chrysin In Alleviating Mycophenolate-Induced Diarrhea And Its Pharmacokinetics Profile, Abasifreke Sunday Benson

Theses (2016-Present)

Medication-induced diarrhea is a common adverse effect experienced by patients taking immunosuppressant medications used in Organ transplants. However, Mycophenolate mofetil (MMF) is the first-line drug to prevent organ transplant rejection. (Van Gelder & Hesselink, 2015) . MMF’s mechanism of action involves inhibition of inosine-5'-monophosphate dehydrogenase. It is used for the treatment and management of a variety of autoimmune diseases as well as to prevent organ rejection in patients with bone marrow and solid organ transplants; however, over 50% of its adverse effects have been reported to be diarrhea. (Arslan et al., 2007; Farooqi et al., 2020). However, few options exist …

Engineering Small-Molecule And Protein Drugs For Targeting Bone Tumors, Yixian Wang, Chenhang Wang, Meng Xia, Zeru Tian, Joseph Zhou, Julian Meyer Berger, Xiang H-F Zhang, Han Xiao

Faculty, Staff and Students Publications

Bone cancer is common and severe. Both primary (e.g., osteosarcoma, Ewing sarcoma) and secondary (e.g., metastatic) bone cancers lead to significant health problems and death. Currently, treatments such as chemotherapy, hormone therapy, and radiation therapy are used to treat bone cancer, but they often only shrink or slow tumor growth and do not eliminate cancer completely. The bone microenvironment contributes unique signals that influence cancer growth, immunogenicity, and metastasis. Traditional cancer therapies have limited effectiveness due to off-target effects and poor distribution on bones. As a result, therapies with improved specificity and efficacy for treating bone tumors are highly needed. …
