BACKGROUND: Recent data have demonstrated that overall mortality and adverse events are not significantly different for primary repair (PR) and staged repair (SR) approaches to management of neonates with symptomatic tetralogy of Fallot (sTOF). Cost data can be used to compare the relative value (cost for similar outcomes) of these approaches and are a potentially more sensitive measure of morbidity.

OBJECTIVES: This study sought to compare the economic costs associated with PR and SR in neonates with sTOF.

METHODS: Data from a multicenter retrospective cohort study of neonates with sTOF were merged with administrative data to compare total costs and …

Neural stem cells, the source of newborn neurons in the adult hippocampus, are intimately involved in learning and memory, mood, and stress response. Despite considerable progress in understanding the biology of neural stem cells and neurogenesis, regulating the neural stem cell population precisely has remained elusive because we have lacked the specific targets to stimulate their proliferation and neurogenesis. The orphan nuclear receptor TLX/NR2E1 governs neural stem and progenitor cell self-renewal and proliferation, but the precise mechanism by which it accomplishes this is not well understood because its endogenous ligand is not known. Here, we identify oleic acid (18:1ω9 monounsaturated …

Faculty, Staff and Students Publications

The prevalence and treatment of chlamydia (CT) and gonorrhea (GC) at school-based clinics (SBCs) requires revisiting. To assess whether clinic type influences CT/GC testing and treatment for minors (individuals 13–17 years of age), our study compared four SBCs with five family planning clinics (FPCs) in the Houston, Harris County metropolitan area of Texas, USA for: (1) the prevalence of CT/GC infection (pre-COVID-19 and during COVID-19); (2) treatment rates at the last positive diagnosis; and (3) the time, in days, from testing-to-diagnosis and testing-to-treatment. Between January 2019 and December 2020, 2439 unique patients (1579 at SBCs, 860 at FPCs) were seen. …

Wwox Binding To The Murine Brca1-Brct Domain Regulates Timing Of Brip1 And Ctip Phospho-Protein Interactions With This Domain At Dna Double-Strand Breaks, And Repair Pathway Choice, Dongju Park, Mehdi Gharghabi, Colleen R Reczek, Rebecca Plow, Charles Yungvirt, C Marcelo Aldaz, Kay Huebner

Faculty, Staff and Student Publications

Wwox-deficient human cells show elevated homologous recombination, leading to resistance to killing by double-strand break-inducing agents. Human Wwox binds to the Brca1 981-PPLF-984 Wwox-binding motif, likely blocking the pChk2 phosphorylation site at Brca1-S988. This phosphorylation site is conserved across mammalian species; the PPLF motif is conserved in primates but not in rodents. We now show that murine Wwox does not bind Brca1 near the conserved mouse Brca1 phospho-S971 site, leaving it open for Chk2 phosphorylation and Brca1 activation. Instead, murine Wwox binds to Brca1 through its BRCT domain, where pAbraxas, pBrip1, and pCtIP, of the A, B, and C binding …

BACKGROUND: We recently conducted Cetuximab-AVElumab-Lung (CAVE-Lung), a proof-of-concept, translational and clinical trial, to evaluate the combination of two IgG1 monoclonal antibodies (mAb): avelumab, an anti-PD-L1 drug, and cetuximab, an anti-epidermal growth factor receptor (EGFR) drug, as second- or third-line treatment in non-small cell lung cancer (NSCLC) patients. We have reported clinically relevant anti-tumor activity in 6/16 patients. Clinical benefit was accompanied by Natural Killer (NK) cell-mediated antibody-dependent cell cytotoxicity (ADCC). Among the 6 responding patients, 3 had progressed after initial response to a previous treatment with single agent anti-PD-1, nivolumab or pembrolizumab.

METHODS: We report long-term clinical follow-up and additional …

Newborn Screening: Review Of Its Impact For Cystinosis, Katharina Hohenfellner, Ewa Elenberg, Gema Ariceta, Galina Nesterova, Neveen A Soliman, Rezan Topaloglu

Faculty, Staff and Students Publications

Newborn screening (NBS) programmes are considered to be one of the most successful secondary prevention measures in childhood to prevent or reduce morbidity and/or mortality via early disease identification and subsequent initiation of therapy. However, while many rare diseases can now be detected at an early stage using appropriate diagnostics, the introduction of a new target disease requires a detailed analysis of the entire screening process, including a robust scientific background, analytics, information technology, and logistics. In addition, ethics, financing, and the required medical measures need to be considered to allow the benefits of screening to be evaluated at a …

Journal of Nursing & Interprofessional Leadership in Quality & Safety

Background: The healthcare field is experiencing rapid growth in the number of advanced practice providers (APPs) with projections that demonstrate that this trend will only continue. Even though the number of APPs is growing, the development of facility-specific APP management infrastructure often grows at a slower pace. Specific policies and procedures on APP utilization and clinical efficiency metrics are lacking. This can lead to deficiencies in the understanding of the education and practice boundaries of APPs.

Objective: Our study aimed to analyze the growth and utilization of physician assistants (PAs) in several hospitals located within Texas Medical Center (TMC) …

Targeted Dual-Modal Pet/Spect-Nir Imaging: From Building Blocks And Construction Strategies To Applications, Syed Muhammad Usama, Sierra C Marker, Servando Hernandez Vargas, Solmaz Aghaamiri, Sukhen C Ghosh, Naruhiko Ikoma, Hop S Tran Cao, Martin J Schnermann, Ali Azhdarinia

Faculty, Staff and Student Publications

Molecular imaging is an emerging non-invasive method to qualitatively and quantitively visualize and characterize biological processes. Among the imaging modalities, PET/SPECT and near-infrared (NIR) imaging provide synergistic properties that result in deep tissue penetration and up to cell-level resolution. Dual-modal PET/SPECT-NIR agents are commonly combined with a targeting ligand (e.g., antibody or small molecule) to engage biomolecules overexpressed in cancer, thereby enabling selective multimodal visualization of primary and metastatic tumors. The use of such agents for (i) preoperative patient selection and surgical planning and (ii) intraoperative FGS could improve surgical workflow and patient outcomes. However, the development of targeted dual-modal …

Micrornas In Leukemias: A Clinically Annotated Compendium, Aleksander Turk, George A Calin, Tanja Kunej

Faculty, Staff and Student Publications

Leukemias are a group of malignancies of the blood and bone marrow. Multiple types of leukemia are known, however reliable treatments have not been developed for most leukemia types. Furthermore, even relatively reliable treatments can result in relapses. MicroRNAs (miRNAs) are a class of short, noncoding RNAs responsible for epigenetic regulation of gene expression and have been proposed as a source of potential novel therapeutic targets for leukemias. In order to identify central miRNAs for leukemia, we conducted data synthesis using two databases: miRTarBase and DISNOR. A total of 137 unique miRNAs associated with 16 types of leukemia were retrieved …

Paradoxical Effects Of Osteoprotegerin On Vascular Function: Inhibiting Inflammation While Promoting Oxidative Stress?, Nhat-Tu Le, Elizabeth A Olmsted-Davis, Jun-Ichi Abe

Faculty, Staff and Student Publications

Osteoprotegerin (OPG), also known as osteoclastogenesis inhibitory factor or tumor necrosis factor receptor superfamily member 11B, is well known as a modulator of bone remodeling. The contribution of OPG to cardiovascular disease (CVD) has been suggested, but its molecular mechanism is complex and remains unclear. In the present study, Alves-Lopes et al. (Clin. Sci. (Lond.) (2021) 135(20): https://doi.org/10.1042/CS20210643) reported the critical role of syndecan-1 (SDC-1, also known as CD138), a surface protein part of the endothelial glycocalyx, in OPG-induced vascular dysfunction. The authors found that in endothelial cells (ECs), through SDC-1, OPG increased eNOS Thr495 phosphorylation, thereby inhibiting eNOS activity. …

Bulk and single-cell RNA sequencing do not provide full characterization of tissue spatial diversity in cancer samples, and currently available in situ techniques (multiplex immunohistochemistry and imaging mass cytometry) allow for only limited analysis of a small number of targets. The current study represents the first comprehensive approach to spatial transcriptomics of high-grade serous ovarian carcinoma using intact tumor tissue. We selected a small cohort of patients with highly annotated high-grade serous ovarian carcinoma, categorized them by response to neoadjuvant chemotherapy (poor or excellent), and analyzed pre-treatment tumor tissue specimens. Our study uncovered extensive differences in tumor composition between the …

Skp2 Stabilizes Mcl-1 And Confers Radioresistance In Colorectal Cancer, Xinfang Yu, Li Zhou, Wenbin Liu, Lijun Liu, Feng Gao, Wei Li, Haidan Liu

Faculty, Staff and Students Publications

Overexpression of Skp2 plays a critical role in tumorigenesis and correlates with poor prognosis in human malignancies. Thus, Skp2 has been proposed as an attractive target for anti-tumor interventions. The expression of Skp2 in human colorectal cancer (CRC) and the role of Skp2 in tumorigenic properties and irradiation sensitivities of CRC cells were examined by anchorage-dependent and -independent growth assays, immunoblot, flow cytometry, immunohistochemical staining, ubiquitination analysis, co-immunoprecipitation assay, CRISPR-Cas9-based gene knockout, and xenograft experiments. Skp2 is highly expressed in CRC patient tissues. Blocking Skp2 expression reduces the tumorigenic properties of CRC cells in vitro and in vivo. Depletion of …

Climate change and air pollution are twin global public health challenges of high priority. Sharing linked causes and solutions, both climate change and air pollution are suggested by a growing body of research to inflict negative mental health outcomes through multiple mechanisms. However, there are still gaps in understanding the links between climate change, air pollution and mental health, especially in children and adolescents, who are particularly at-risk. Current findings are summarized and their implications for future research as well as public health policies are discussed.

Predicting Health-Related Social Needs In Medicaid And Medicare Populations Using Machine Learning, Jennifer Holcomb, Luis C Oliveira, Linda Highfield, Kevin O Hwang, Luca Giancardo, Elmer Victor Bernstam

Faculty, Staff and Student Publications

Providers currently rely on universal screening to identify health-related social needs (HRSNs). Predicting HRSNs using EHR and community-level data could be more efficient and less resource intensive. Using machine learning models, we evaluated the predictive performance of HRSN status from EHR and community-level social determinants of health (SDOH) data for Medicare and Medicaid beneficiaries participating in the Accountable Health Communities Model. We hypothesized that Medicaid insurance coverage would predict HRSN status. All models significantly outperformed the baseline Medicaid hypothesis. AUCs ranged from 0.59 to 0.68. The top performance (AUC = 0.68 CI 0.66-0.70) was achieved by the "any HRSNs" outcome, …

Gut-Derived Butyrate Suppresses Ocular Surface Inflammation, Laura Schaefer, Humberto Hernandez, Rosalind A Coats, Zhiyuan Yu, Stephen C Pflugfelder, Robert A Britton, Cintia S De Paiva

Faculty, Staff and Students Publications

Dry eye is a common ocular inflammatory disorder characterized by tear film instability and reduced tear production. There is increasing evidence that homeostasis of the ocular surface is impacted by the intestinal microbiome. We are interested in investigating the potential role of microbially produced small molecules in mediating the interaction between the intestinal microbiota and the ocular surface. One such molecule is butyrate, a short-chain fatty acid (SCFA) produced by certain members of the gut microbiota through fermentation of dietary fiber. Here we show that SCFA transporter SLC5A8 is expressed in vivo in murine conjunctival and corneal epithelium. Pre-treatment of …
