Quantifying The Impact Of Laboratory And Care Systems On Relinkage To Hiv Care In A Southern, Urban Environment, Kellie L. Watkins

Dissertations and Theses (Open Access)

Background: HIV viral suppression reduces the likelihood of transmission to just 5%,1 demonstrating the critical link between care and prevention, yet only 51% of people living with HIV (PLWH) were retained in care and 46% achieved viral suppression in the Houston area (2012), with the out-of-care (OOC) population increasing between 2008-2011.2,3

Methods: Record-search investigations across HIV surveillance and care data systems determined if potentially OOC persons referred to the Houston Health Department (HHD) from 2013-2015 (N=1287) qualified for public health follow up. A portion were randomized to a non-intervention group (n=200) to assess the program effectiveness. Participants without a disposition …

IL-1α Blockade Reduces Immune Suppression in the Early Tumor Micro-Environment

Brenda Melendez, B.S.

Advisory Professor: Gregory Lizee, PhD.

Immunotherapy against melanoma has shown great promise in the clinic for treating advanced-stage patients. However, a major barrier against effective T cell mediated cytotoxicity is immunosuppression in the tumor micro-environment. It has been described that tumors secrete pro-inflammatory cytokines capable of modulating immune responses that favors the growth of tumor cells. Specifically, IL-1 plays a critical role in myeloid cell recruitment and activation, which can in turn inhibit T cell activity in vivo. Moreover, IL-1 is also known to up-regulate immune inhibitory …

Effects Of A Community Population Health Initiative On Blood Pressure Control In Latinos, James R Langabeer, Timothy D Henry, Carlos Perez Aldana, Larissa Deluna, Nora Silva, Tiffany Champagne-Langabeer

Faculty, Staff and Student Publications

Background Hypertension remains one of the most important, modifiable cardiovascular risk factors. Yet, the largest minority ethnic group (Hispanics/Latinos) often have different health outcomes and behavior, making hypertension management more difficult. We explored the effects of an American Heart Association-sponsored population health intervention aimed at modifying behavior of Latinos living in Texas. Methods and Results We enrolled 8071 patients, and 5714 (65.7%) completed the 90-day program (58.5 years ±11.7; 59% female) from July 2016 to June 2018. Navigators identified patients with risk factors; initial and final blood pressure ( BP ) readings were performed in the physician's office; and interim …

Reframing Human Trafficking: From A Criminal Justice Problem To A Social Justice Issue, Rebecca Pfeffer

Journal of Family Strengths

Laws addressing human trafficking have been passed in all 50 U.S. states as well as at the federal level. Although laws serve an important function in establishing social norms against a behavior, they can also create a belief that it is the responsibility of law enforcement to curb that behavior. Law enforcement and other actors in the criminal justice system have a critical role to play in addressing the problem of human trafficking, but this is not a problem that they can solve alone. A multipronged strategy engaging the fields of public health, medicine, social work, and criminal justice as …

Examining The Myth Of Accountability, High-Stakes Testing, And The Achievement Gap, Julian Vasquez Heilig, T. Jameson Brewer, Jimmy Ojeda Pedraza

Journal of Family Strengths

In this article we outline how notions of accountability and the achievement gap have relied upon the massive expansion of high-stakes exams in our nation’s schools. Texas-style test and punish accountability manifested in various ways within schools and school culture across the nation via NCLB, which undermined notions of trust within education. More than decade of national education policy focused on high-stakes testing and accountability—despite that the fact that the rise of high-stakes testing also involved considerable legal, ethical, and social considerations. We argue the practice of spending large amounts of time on test preparation and test taking must be …

Exome Sequencing Identifies Gene Variants And Networks Associated With Extreme Respiratory Outcomes Following Preterm Birth, Aaron Hamvas, Rui Feng, Yingtao Bi, Fan Wang, Soumyaroop Bhattacharya, Jared Mereness, Madhurima Kaushal, C Michael Cotten, Philip L Ballard, Thomas J Mariani

Faculty, Staff and Student Publications

BACKGROUND: Previous studies have identified genetic variants associated with bronchopulmonary dysplasia (BPD) in extremely preterm infants. However, findings with genome-wide significance have been rare, and not replicated. We hypothesized that whole exome sequencing (WES) of premature subjects with extremely divergent phenotypic outcomes could facilitate the identification of genetic variants or gene networks contributing disease risk.

RESULTS: The Prematurity and Respiratory Outcomes Program (PROP) recruited a cohort of > 765 extremely preterm infants for the identification of markers of respiratory morbidity. We completed WES on 146 PROP subjects (85 affected, 61 unaffected) representing extreme phenotypes of early respiratory morbidity. We tested for …

BACKGROUND: Aspirin is a well-established therapy for the secondary prevention of cardiovascular events. However, its role in the primary prevention of cardiovascular disease is unclear, especially in older persons, who have an increased risk.

METHODS: From 2010 through 2014, we enrolled community-dwelling men and women in Australia and the United States who were 70 years of age or older (or ≥65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or disability. Participants were randomly assigned to receive 100 mg of enteric-coated aspirin or placebo. The primary end point was a …

Effect Of Aspirin On All-Cause Mortality In The Healthy Elderly, John J Mcneil, Mark R Nelson, Robyn L Woods, Jessica E Lockery, Rory Wolfe, Christopher M Reid, Brenda Kirpach, Raj C Shah, Diane G Ives, Elsdon Storey, Joanne Ryan, Andrew M Tonkin, Anne B Newman, Jeff D Williamson, Karen L Margolis, Michael E Ernst, Walter P Abhayaratna, Nigel Stocks, Sharyn M Fitzgerald, Suzanne G Orchard, Ruth E Trevaks, Lawrence J Beilin, Geoffrey A Donnan, Peter Gibbs, Colin I Johnston, Barbara Radziszewska, Richard Grimm, Anne M Murray

Faculty, Staff and Student Publications

BACKGROUND: In the primary analysis of the Aspirin in Reducing Events in the Elderly (ASPREE) trial, now published in the Journal, we report that the daily use of aspirin did not provide a benefit with regard to the primary end point of disability-free survival among older adults. A numerically higher rate of the secondary end point of death from any cause was observed with aspirin than with placebo.

METHODS: From 2010 through 2014, we enrolled community-dwelling persons in Australia and the United States who were 70 years of age or older (or ≥65 years of age among blacks and Hispanics …

BACKGROUND: Information on the use of aspirin to increase healthy independent life span in older persons is limited. Whether 5 years of daily low-dose aspirin therapy would extend disability-free life in healthy seniors is unclear.

METHODS: From 2010 through 2014, we enrolled community-dwelling persons in Australia and the United States who were 70 years of age or older (or ≥65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or physical disability. Participants were randomly assigned to receive 100 mg per day of enteric-coated aspirin or placebo orally. The primary end …

Knockdown Of Crispld2 In Zebrafish Identifies A Novel Network For Nonsyndromic Cleft Lip With Or Without Cleft Palate Candidate Genes, Brett T Chiquet, Qiuping Yuan, Eric C Swindell, Lorena Maili, Robert Plant, Jeffrey Dyke, Ryan Boyer, John F Teichgraeber, Matthew R Greives, John B Mulliken, Ariadne Letra, Susan H Blanton, Jacqueline T Hecht

Orofacial development is a multifaceted process involving tightly regulated genetic signaling networks, that when perturbed, lead to orofacial abnormalities including cleft lip and/or cleft palate. We and others have shown an association between the cysteine-rich secretory protein LCCL domain containing 2 (CRISPLD2) gene and nonsyndromic cleft lip with or without cleft palate (NSCLP). Further, we demonstrated that knockdown of Crispld2 in zebrafish alters neural crest cell migration patterns resulting in abnormal jaw and palate development. In this study, we performed RNA profiling in zebrafish embryos and identified 249 differentially expressed genes following knockdown of Crispld2. In silico pathway analysis identified …

Addressing Youth Perceptions Of Harm In Marijuana Prevention Programming, Kristen J. Quinlan, Maria Valenti, Gisela Rots, Joshua Esrick, Kimberly Dash

Journal of Applied Research on Children: Informing Policy for Children at Risk

The inverse relationship between perception of harm and substance use is clearly supported by decades of research – youth are less likely to engage in substance use when it is seen as harmful. However, despite strong theoretical and practical reasons to focus on perception of harm as a change-producer in prevention programming, little is known about what is effective in impacting perception of harm for youth marijuana use.

To investigate the impact of existing prevention efforts designed to influence youth perception of harm and, consequently, youth marijuana use, we reviewed seven privately- or federally-funded online registries (e.g., Blueprints for Healthy …

Ontology-Based Clinical Information Extraction Using Snomed Ct, Jun Li

Dissertations and Theses (Open Access)

Extracting and encoding clinical information captured in unstructured clinical documents with standard medical terminologies is vital to enable secondary use of clinical data from practice. SNOMED CT is the most comprehensive medical ontology with broad types of concepts and detailed relationships and it has been widely used for many clinical applications. However, few studies have investigated the use of SNOMED CT in clinical information extraction.

In this dissertation research, we developed a fine-grained information model based on the SNOMED CT and built novel information extraction systems to recognize clinical entities and identify their relations, as well as to encode them …

An Expanded Toolkit For Gene Tagging Based On Mimic And Scarless Crispr Tagging In, David Li-Kroeger, Oguz Kanca, Pei-Tseng Lee, Sierra Cowan, Michael T Lee, Manish Jaiswal, Jose Luis Salazar, Yuchun He, Zhongyuan Zuo, Hugo J Bellen

We generated two new genetic tools to efficiently tag genes in Drosophila. The first, Double Header (DH) utilizes intronic MiMIC/CRIMIC insertions to generate artificial exons for GFP mediated protein trapping or T2A-GAL4 gene trapping in vivo based on Cre recombinase to avoid embryo injections. DH significantly increases integration efficiency compared to previous strategies and faithfully reports the expression pattern of genes and proteins. The second technique targets genes lacking coding introns using a two-step cassette exchange. First, we replace the endogenous gene with an excisable compact dominant marker using CRISPR making a null allele. Second, the insertion is replaced …

Meta-Analysis Of The Incidence And Patterns Of Second Neoplasms After Photon Craniospinal Irradiation In Children With Medulloblastoma, Abhishek Bavle, Sayani Tewari, Amy Sisson, Murali Chintagumpala, Michael Anderson, Arnold C Paulino

Library Staff Publications

BACKGROUND: Second neoplasms (SNs) are a well-established long-term adverse effect of radiation therapy (RT), but there are limited data regarding their incidence and location relative to the radiation field, specific to medulloblastoma (MB) survivors after craniospinal irradiation (CSI).

METHODS: A systematic literature review, per Preferred Reporting Items for Systematic Reviews and Meta-Analyses, identified six studies reporting the incidence and locations of SNs for 1,114 patients with MB, after CSI, with a median follow-up of ∼9 years (7.6-15.4 years). The study-specific cumulative incidence (CI) of SNs, second benign neoplasms (SBNs), and second malignant neoplasms (SMNs) were standardized to a 10-year time …

High-Risk Cardiovascular Conditions In Sports-Related Sudden Death: Prevalence In 5,169 Schoolchildren Screened Via Cardiac Magnetic Resonance, Paolo Angelini, Benjamin Y Cheong, Veronica V Lenge De Rosen, Alberto Lopez, Carlo Uribe, Anthony H Masso, Syed W Ali, Barry R Davis, Raja Muthupillai, James T Willerson

The Texas Heart Institute Journal

Improving preparticipation screening of candidates for sports necessitates establishing the prevalence of high-risk cardiovascular conditions (hr-CVC) that predispose young people to sudden cardiac death (SCD). Our accurate, novel protocol chiefly involved the use of cardiac magnetic resonance (CMR) to estimate this prevalence.

Middle and high school students from a general United States population were screened by means of questionnaires, resting electrocardiograms, and CMR to determine the prevalence of 3 types of hr-CVC: electrocardiographic abnormalities, cardiomyopathies, and anomalous coronary artery origin from the opposite sinus with intramural coronary course (ACAOS-IM). We examined the range of normal left ventricular size and function …

Prognostic Performance Of Prospective Versus Retrospective Electrocardiographic Gating In Coronary Computed Tomographic Angiography, Pradnya Velankar, Kongkiat Chaikriangkrai, Ninad Dewal, Sayf Khaleel Bala, Belqis Elferjani, Sama Alchalabi, Su Min Chang

The Texas Heart Institute Journal

Coronary computed tomographic angiography (CCTA) with prospective electrocardiographic gating reduces radiation exposure, but its prognostic power for predicting cardiovascular risk in patients with suspected CAD has not been fully validated. To determine whether prospective gating performs as well as retrospective gating in this population, we compared these scan modes in patients undergoing 64-slice CCTA.

From January 2009 through September 2011, 1,407 patients underwent CCTA; of these, 915 (mean age, 57.8 ± 13.5 yr; 54% male) had suspected coronary artery disease at the time of CCTA and were included in the study. Prospective gating was used in 195 (21%) and retrospective …

Characterizing The Recognition Motif And Novel Substrates Of Carm1, Sitaram Gayatri

Dissertations and Theses (Open Access)

A limited pool of proteins attains vast functional repertoire due to posttranslational modifications (PTMs). Arginine methylation is a common posttranslational modification, which is catalyzed by a family of nine protein arginine methyltransferases or PRMTs. These enzymes deposit one or two methyl groups to the nitrogen atoms of arginine side-chains. Elucidating the substrate specificity of each PRMT will promote a better understanding of which signaling networks these enzymes contribute to. Although many PRMT substrates have been identified, and their methylation sites mapped, the optimal target motif for each of the nine PRMTs has not been systematically addressed. Here we describe the …

With the increasing availability of genomics, routine analysis of advanced cancers is now feasible. Treatment selection is frequently guided by the molecular characteristics of a patient's tumor, and an increasing number of trials are genomically selected. Furthermore, multiple studies have demonstrated the benefit of therapies that are chosen based upon the molecular profile of a tumor. However, the rapid evolution of genomic testing platforms and emergence of new technologies make interpreting molecular testing reports more challenging. More sophisticated precision oncology decision support services are essential. This review outlines existing tools available for health care providers and precision oncology teams and …

Glucose-6-Phosphate Dehydrogenase Deficiency Is Associated With Cardiovascular Disease In Us Military Centers, John E Thomas, Seungho Kang, Charles J Wyatt, Forest S Kim, A David Mangelsdorff, Fred K Weigel

The Texas Heart Institute Journal

Glucose-6-phosphate dehydrogenase (G6PD) protects erythrocytes from oxidative stress and hemolysis; G6PD deficiency is the most prevalent enzymopathy. The United States military routinely performs tests to prevent exposing G6PD-deficient personnel to antimalarial drugs that might cause life-threatening hemolytic reactions. In addition, G6PD is a key determinant of vascular function, and its deficiency can lead to impaired nitric oxide production and greater vascular oxidant stress—precursors to atherosclerosis and cardiovascular disease. Using military medical records, we performed a retrospective, cross-sectional study to investigate whether deficient G6PD levels are associated with a higher prevalence of cardiovascular disease than are normal levels, and, if so, …
