Save The Rich, Connor Harris

English Department: Research for Change - Wicked Problems in Our World

The problem of medication pricing and lobbying in the healthcare industry has caused millions of people within the United States to not be able to afford medications essential to their lives. Pharmaceutical companies are taking advantage of the need people have for certain drugs by setting the sale price far higher than it costs to produce. My suggested solution is to make lobbying illegal in the United States so that pharmaceutical companies would not have control over government officials who pass laws to help or hurt the issue of medication pricing. Illegalizing government lobbying will take away the incentive politicians …

How The Symptoms And Conditions Associated With Diabetes Can Impact Mobility And Health Of The Individual: A Literature Review, Kaitlin Grace Fotis

Honors Projects

A literature review on diabetes, diabetic neuropathy, diabetic amyotrophy, sores, ulcers, and amputations, and nephropathy and how, through this snowballing journey, physical therapy can aid an individual. Diabetes can impact the mortality and morbidity of an individual and it alone can have lifelong effects upon the individual. These effects may include dependency upon medication, lifestyle modifications, and diet and physical activity guidelines. If their condition were to worsen, they could find themselves battling circulatory issues and neuropathy thereby hindering their physical function. Many individuals with circulatory issues, diabetic neuropathy, and diabetic amyotrophy develop injuries on their feet like ulcers and …

The Transcriptional Trajectories Of Pluripotency And Differentiation Comprise Genes With Antithetical Architecture And Repetitive-Element Content., Aristeidis G. Telonis, Isidore Rigoutsos

Computational Medicine Center Faculty Papers

BACKGROUND: Extensive molecular differences exist between proliferative and differentiated cells. Here, we conduct a meta-analysis of publicly available transcriptomic datasets from preimplantation and differentiation stages examining the architectural properties and content of genes whose abundance changes significantly across developmental time points.

RESULTS: Analysis of preimplantation embryos from human and mouse showed that short genes whose introns are enriched in Alu (human) and B (mouse) elements, respectively, have higher abundance in the blastocyst compared to the zygote. These highly expressed genes encode ribosomal proteins or metabolic enzymes. On the other hand, long genes whose introns are depleted in repetitive elements have …

The Qualitative Report

Qualitative health research plays a central role in exploring individuals’ experiences and perceptions of wellness, illness, and healthcare services. Visual tools are increasingly used for data elicitation. An ecomap is a visual tool that applies ecosystems theory to human communities and relationships to provide an illustration of the quality of relationships. We describe the use of ecomaps in qualitative health research. Searches across eight databases identified 407 citations. We screened them in duplicate to identify 129 publications that underwent full text review and included 73 in the final synthesis. We classified and summarized data based on iterative comparisons across sources. …

Machine Learning Approaches Identify Genes Containing Spatial Information From Single-Cell Transcriptomics Data., Phillipe Loher, Nestoras Karathanasis

Computational Medicine Center Faculty Papers

The development of single-cell sequencing technologies has allowed researchers to gain important new knowledge about the expression profile of genes in thousands of individual cells of a model organism or tissue. A common disadvantage of this technology is the loss of the three-dimensional (3-D) structure of the cells. Consequently, the Dialogue on Reverse Engineering Assessment and Methods (DREAM) organized the Single-Cell Transcriptomics Challenge, in which we participated, with the aim to address the following two problems: (a) to identify the top 60, 40, and 20 genes of the Drosophila melanogaster embryo that contain the most spatial information and (b) to …

Factors Contributing To Diminished Long-Term Outcomes Of Secondary Infections, Alia Tayara

Undergraduate Theses

It is widely known that patients suffer diminished long-term outcomes in the years following secondary infections, infectious diseases that occur during or after treatment of a primary infection such as influenza or COVID-19. One common secondary infection is pneumonia, which has become the most fatal hospital-acquired infection. The bacterium responsible for pneumonia is known as Pseudomonas aeruginosa. The cytotoxic supernatant in these studies was generated from a PA103 strain of Psuedomonas aeruginosa with a type III secretion system that maintains the ability to transfer exoenzymes ExoU and ExoT into target cells during infection. The focus of the following studies was …

Covid-19 Media Exposure And Parenting, Abagail Roy

Undergraduate Theses

Rationale- The COVID-19 pandemic has led to a drastic change in the way of living for most parents. A study conducted during the lockdown of Italy found that parents experienced a high level of distress (Marchetti et al., 2020). Several studies have been conducted to find how media exposure and screen time affect children but much less research has been conducted on how media exposure is related to parental feelings and parenting.

Methods- The aim of this paper is to explore the role of COVID-19 media exposure in parental aggravation, closeness to children, parental self-regulation, intolerance of uncertainty, and resourcefulness. …

Utilizing Acoustic Levitation To Determine Ionic Liquid Effects On Enthalpy Of Polymerization, Davina V. Ho

Undergraduate Theses

Ionic liquids (ILs) are emerging as an eco-friendlier alternative to traditional organic compounds. The hope with ILs in this project is to incorporate them with resins used in 3D printing to act as plasticizers which will in turn help prolong the life of the printed object. A common issue with plasticizers like phthalate in particular is they can leach out of plastics due to their vapor pressure which leads to decreased performance and can also pose a health risk being released into its surroundings or atmosphere. A major benefit of incorporating ILs in with resins comes from their low volatility …

Integrative Genome Assembly Of Staphylococcus Epidermidis And Staphylococcus Hominis Strains, Cana L. Brown

Undergraduate Theses

Due to rapid advances in sequencing technology, it is becoming increasingly easier to assemble unknown genomes from millions of short sequencing reads of nucleotides taken from the full genomic sequence (Hernandez, 2008). In this study, we used various computational programs to align reads from unsequenced strains of the bacteria Staphylococcus epidermidis and Staphylococcus hominis into a hitherto undefined, single contiguous genomic sequence. We used SPAdes to assist with template free assembly (Bankevich, 2012), BLAST to identify a suitable reference genome from closely related species (Madden, 2013), Bowtie2 to align our reads to the reference genome, SAMtools to sort and organize …

Health Promotion and Policy Faculty Publication Series

Parents of children with rare diseases often face uncertainty about diagnosis, treatment, and costs associated with healthcare for their child. Health insurance status impacts each of these areas, but no U.S. study has explored parents' perceptions of the health insurance impacts on their child's care. This study aimed to qualitatively explore how these parents navigate the complex health insurance system for their children and their experiences in doing so. Methods Semi-structured interviews were conducted with parents of children with metachromatic leukodystrophy (MLD) and spinal muscular atrophy (SMA), chosen for specific disease characteristics and orphan drug status. Participants were recruited via …

Evaluating Epidemic Forecasts In An Interval Format, Johannes Bracher, Evan L. Ray, Tilmann Gneiting, Nicholas G. Reich

Biostatistics and Epidemiology Faculty Publications Series

For practical reasons, many forecasts of case, hospitalization, and death counts in the context of the current Coronavirus Disease 2019 (COVID-19) pandemic are issued in the form of central predictive intervals at various levels. This is also the case for the forecasts collected in the COVID-19 Forecast Hub (https://covid19forecasthub.org/). Forecast evaluation metrics like the logarithmic score, which has been applied in several infectious disease forecasting challenges, are then not available as they require full predictive distributions. This article provides an overview of how established methods for the evaluation of quantile and interval forecasts can be applied to epidemic forecasts in …

Opioid Use Disorder: The Timeline For Medication Assisted Therapy, Alexander Cristofori

Capstone Showcase

Opioid Use Disorder is patterns of opioid use leading to withdrawal, giving up important life events in order to use opioids, and excessive time spent using opioids, to name a few diagnostic criteria. The clinical progression of the disorder involves periods of acute exacerbation and remission that are cyclic in nature. Treatment is most effective when it includes both pharmacological and psychosocial modalities, referred to as medication assisted therapy (MAT). Three drugs used commonly in MAT-based treatment for OUD from oldest to newest include Methadone, Buprenorphine-naloxone, and Naltrexone. Treatment program models that prioritize total abstinence from the addictive substance attached …

Multivariate Distributions Of Correlated Binary Variables Generated By Pair-Copulas, Huihui Lin, N. Rao Chaganty

Mathematics & Statistics Faculty Publications

Correlated binary data are prevalent in a wide range of scientific disciplines, including healthcare and medicine. The generalized estimating equations (GEEs) and the multivariate probit (MP) model are two of the popular methods for analyzing such data. However, both methods have some significant drawbacks. The GEEs may not have an underlying likelihood and the MP model may fail to generate a multivariate binary distribution with specified marginals and bivariate correlations. In this paper, we study multivariate binary distributions that are based on D-vine pair-copula models as a superior alternative to these methods. We elucidate the construction of these binary distributions …

Short Term Effects Of Electronic Cigarettes On Pulmonary Function In Healthy Adult Smokers When Compared To Conventional Cigarette Use, Kayleen Lynch, Rachel Bastianelli

Physician Assistant Capstones, 2020-current

Background: Electronic cigarettes (e-cigarettes) first appeared on the U.S. market in 20071 , but to date, little is known about their safety. Concern about long term adverse effects on overall health continues to increase as we explore the potential of e-cigarettes to aid in smoking cessation practices. E-cigarettes have gained popularity and support through this idea that by using them to help patients quit smoking, the benefits of ultimately abstaining from tobacco use will outweigh the harms associated with e-cigarette use1 . While the idea of reducing tobacco usage by any means possible remains the goal for most providers, without …

Apneic Oxygenation: An Adjunctive Therapy For Laryngoscopy During Anesthesia Induction, Yaro Hoffman

Doctoral Projects

Endotracheal intubation is an essential component within the skill set of anesthesia providers. Rapid arterial desaturation remains a primary risk factor during laryngoscopy and intubation. The risk for hypoxemia exists because during endotracheal intubation, patients are apneic or hypo-ventilating (Wong et al., 2017). Apneic oxygenation (AO) has been advocated to attenuate hypoxemia during endotracheal intubation (Pavlov et al., 2017).

The aim of this project was to assess for any knowledge deficits regarding AO among anesthesia providers and assess the willingness of these providers to include AO into their current practice. The project investigator conducted an education session involving the …

COVID-19 Papers, Posters, and Presentations

The COVID-19 crisis has had an unprecedented impact on resident education and well-being: social distancing guidelines have limited patient volumes and forced virtual learning, while personal protective equipment (PPE) shortages, school/daycare closures, and visa restrictions have served as additional stressors. Our study aimed to analyze the effects of COVID-19 crisis-related stressors on residents' professional and personal lives. In April 2020, we administered a survey to residents at a large academic hospital system in order to assess the impact of the pandemic on residency training after >6 weeks of a modified schedule. The primary outcome was to determine which factors or …

Nuclear-Targeted Gold Nanoparticles Enhance The Effects Of Radiation Therapy With And Without Liposomal Delivery, Maureen Aliru

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Less that 10% of pancreatic cancer patients are eligible for curative resection, and clinical trials evaluating chemoradiation in locally advanced patients with unresectable disease have been largely disappointing. New and creative therapeutic approaches are needed to address the unment need for treatment options. The objective of this thesis is to advance radiosensitization of treatment-resistant densely desmoplastic pancreatic cancer using nanoparticles to surmount biological barriers to effective particle distribution for DNA-targeting.

Clinical translation of radiosensitizing nanoparticles has stalled owing to technical challenges. Current strategies to use AuNPs for radiosensitization require large quantities of gold, kilovoltage x-rays, immediate irradiation after intravenous administration, …
