Association Of Alcohol Use And Physical Activity With Body Mass Index In Mexican-Origin Adults, Natalia I Heredia, Qiong Dong, Shine Chang, Lorna H Mcneill

Faculty, Staff and Student Publications

BACKGROUND: Studies across racial/ethnic groups indicate that physical activity (PA) and alcohol consumption are positively associated, and that alcohol consumption is negatively associated with body mass index (BMI), but this relationship is less often evaluated in Hispanics. The purpose of this study was to assess the relationships between alcohol consumption, PA, and BMI in Hispanic adults.

METHODS: In this secondary data analysis of a Mexican-American cohort, we collected self-reported PA, alcohol consumption, and demographics, and measured height and weight. Linear regression assessed the association between PA and alcohol consumption with BMI, controlling for covariates. Total sample for analyses was n …

Nexmif Pathogenic Variants In Individuals Of Korean, Vietnamese, And Mexican Descent, Elizabeth Langley, Laura S Farach, Mary K Koenig, Hope Northrup, David F Rodriguez-Buritica, Kate Mowrey

Faculty, Staff and Student Publications

NEXMIF pathogenic variants have been known to produce a wide spectrum of X-linked intellectual disability (ID) in both males and females. Thus far, few individuals from diverse populations have been described with NEXMIF-related disorders. Herein, we report three individuals with NEXMIF pathogenic variants, the first two are the only males of Korean and Vietnamese descent described with this disorder to our knowledge. The last patient is a Hispanic female who harbors the same pathogenic variant as a previously described Caucasian individual, but with differing clinical presentation. These patients present with many classic symptoms of NEXMIF-related disorders including ID, epilepsy, developmental …

Are Thyrotropin-Releasing Hormone (Trh) And Analog Taltirelin Viable Reversal Agents Of Opioid-Induced Respiratory Depression?, Marieke Hyke Algera, Joseph F Cotten, Monique Van Velzen, Marieke Niesters, Martijn Boon, Daniel S Shoham, Kaye E Dandrea, Rutger Van Der Schrier, Albert Dahan

Faculty, Staff and Student Publications

Opioid-induced respiratory depression (OIRD) is a potentially life-threatening complication of opioid consumption. Apart from naloxone, an opioid antagonist that has various disadvantages, a possible reversal strategy is treatment of OIRD with the hypothalamic hormone and neuromodulator thyrotropin-releasing hormone (TRH). In this review, we performed a search in electronic databases and retrieved 52 papers on the effect of TRH and TRH-analogs on respiration and their efficacy in the reversal of OIRD in awake and anesthetized mammals, including humans. Animal studies show that TRH and its analog taltirelin stimulate breathing via an effect at the preBötzinger complex, an important respiratory rhythm generator …

Alternative splicing is critical for development; however, its role in the specification of the three embryonic germ layers is poorly understood. By performing RNA-Seq on human embryonic stem cells (hESCs) and derived definitive endoderm, cardiac mesoderm, and ectoderm cell lineages, we detect distinct alternative splicing programs associated with each lineage. The most prominent splicing program differences are observed between definitive endoderm and cardiac mesoderm. Integrative multi-omics analyses link each program with lineage-enriched RNA binding protein regulators, and further suggest a widespread role for Quaking (QKI) in the specification of cardiac mesoderm. Remarkably, knockout of QKI disrupts the cardiac mesoderm-associated alternative …

Parental Stress In Tuberous Sclerosis Complex, Jenny Do

Dissertations and Theses (Open Access)

Tuberous Sclerosis Complex (TSC) is a multi-systemic genetic disorder with great clinical variability. As the needs of one child with TSC may vastly differ from another, parenting demands may similarly differ. Characterizing parental stress, or emotional maladaptation arising from parenting duties, can enable healthcare providers to assist parents of children most efficiently with TSC-related symptoms and improve both parent and child health outcomes. This study surveyed 269 parents of children (aged 0-12 years) with TSC and received the following information: children’s TSC clinical features, parent demographics, and a Parent Stress Index (PSI) score. Parents reported higher stress levels for children …

Faculty, Staff and Student Publications

Bipolar disorder (BD) is a severe psychiatric disorder affecting approximately 1-3% of the population and characterized by a chronic and recurrent course of debilitating symptoms. An increasing focus has been directed to discover and explain the function of Blood-Brain Barrier (BBB) integrity and its association with a number of psychiatric disorders; however, there has been limited research in the role of BBB integrity in BD. Multiple pathways may play crucial roles in modulating BBB integrity in BD, such as inflammation, insulin resistance, and alterations of neuronal plasticity. In turn, BBB impairment is hypothesized to have a significant clinical impact in …

Staff and Researcher Publications

Over the last century, many shark populations have declined, primarily due to overexploitation in commercial, artisanal and recreational fisheries. In addition, in some locations the use of shark control programs also has had an impact on shark numbers. Still, there is a general perception that populations of large ocean predators cover wide areas and therefore their diversity is less susceptible to local anthropogenic disturbance. Here we report on temporal genomic analyses of tiger shark (Galeocerdo cuvier) DNA samples that were collected from eastern Australia over the past century. Using Single Nucleotide Polymorphism (SNP) loci, we documented a significant change in …

Inflammatory conditions represent the largest class of chronic skin disease, but the molecular dysregulation underlying many individual cases remains unclear. Single-cell RNA sequencing (scRNA-seq) has increased precision in dissecting the complex mixture of immune and stromal cell perturbations in inflammatory skin disease states. We single-cell-profiled CD45+ immune cell transcriptomes from skin samples of 31 patients (7 atopic dermatitis, 8 psoriasis vulgaris, 2 lichen planus (LP), 1 bullous pemphigoid (BP), 6 clinical/histopathologically indeterminate rashes, and 7 healthy controls). Our data revealed active proliferative expansion of the Treg and Trm components and universal T cell exhaustion in human rashes, with a relative …

Gastrointestinal (GI) symptoms often affect children with autism spectrum disorders (ASD) and GI symptoms have been associated with an abnormal fecal microbiome. There is limited evidence of Candida species being more prevalent in children with ASD. We enrolled 20 children with ASD and GI symptoms (ASD+GI), 10 children with ASD but no GI symptoms (ASD−GI), and 20 from typically developing (TD) children (TD) in this pilot study. Fecal mycobiome taxa were analyzed by ITS sequencing. GI symptoms (GI Severity Index (GSI)), behavioral symptoms (Social Responsiveness Scale −2 (SRS-2)), inflammation and fungal immunity (fecal calprotectin and serum dectin-1 (ELISA)) were evaluated. …

Nonjudgmental Acceptance: Associations With Substance-Related Cue Reactivity In Adults With Substance Use Disorders And Posttraumatic Stress, Anka A Vujanovic, Heather E Webber, Margaret C Wardle, Charles E Green, Scott D Lane, Joy M Schmitz

Faculty, Staff and Student Publications

The present investigation examined the predictive utility of nonjudgmental acceptance, a facet of mindfulness defined as the ability to remain aware and nonevaluative about internal experience, in terms of substance-related cue reactivity among adults with substance use disorders (SUD) and posttraumatic stress (PTS) symptomatology. We hypothesized that higher nonjudgmental acceptance, indexed via self-report, would predict higher levels of self-reported control over oneself and safety 'in the moment', broadly, and lower levels of substance-related craving in response to substance script cues. Effects were expected after subtracting reactivity to neutral script cues from each outcome rating. PTS severity was included as a …

Faculty, Staff and Student Publications

BACKGROUND: An increase in opioid use has led to an opioid crisis during the last decade, leading to declarations of a public health emergency. In response to this call, the Houston Emergency Opioid Engagement System (HEROES) was established and created an emergency access pathway into long-term recovery for individuals with an opioid use disorder. A major contributor to the success of the program is retention of the enrolled individuals in the program.

METHODS: We have identified an increase in dropout from the program after 90 and 120 days. Based on more than 700 program participants, we developed a machine learning …

The Power And Challenge Of Lipid (A)Symmetry Across The Membrane And Cell, Heather E Webber, Joy M Schmitz

Faculty, Staff and Student Publications

Current treatments for substance use disorders (SUDs) are far from ideal, with no U.S. Food and Drug Administration-approved pharmacotherapies to treat stimulant and other use disorders. New approaches are urgently needed to combat the increasing prevalence of SUDs and overdose deaths. It is widely accepted that addiction is a chronic disease of the brain involving changes in neural circuitry associated with cognitive and reward functioning. Brain stimulation techniques are novel methods that can modulate these circuits directly and thus hold considerable promise for treating SUDs.

Staff and Researcher Publications

The genetic basis for the emergence of creativity in modern humans remains a mystery despite sequencing the genomes of chimpanzees and Neanderthals, our closest hominid relatives. Data-driven methods allowed us to uncover networks of genes distinguishing the three major systems of modern human personality and adaptability: emotional reactivity, self-control, and self-awareness. Now we have identified which of these genes are present in chimpanzees and Neanderthals. We replicated our findings in separate analyses of three high-coverage genomes of Neanderthals. We found that Neanderthals had nearly the same genes for emotional reactivity as chimpanzees, and they were intermediate between modern humans and …

Kidney Disease After Heart And Lung Transplantation, Carlos M Zapata, Hassan N Ibrahim

Faculty, Staff and Student Publications

Chronic kidney disease (CKD) is not only common after lung and heart transplantation but also is associated with increased morbidity and mortality due to multiple pre-, peri- and post-transplant factors. While the exact incidence of CKD in this population is not well-defined, it seems to have gradually increased over the years as older recipients are more frequently considered. The increasing success of the procedure and expanding transplant candidate pool has allowed many with comorbid conditions to receive a transplant, which was considered prohibitive in the past. This review presents risk factors that have been linked to CKD as well as …

Accurate estimates of natural and/or vaccine-induced antibodies to SARS-CoV-2 are difficult to obtain. Although model-based estimates of seroprevalence have been proposed, they require inputting unknown parameters including viral reproduction number, longevity of immune response, and other dynamic factors. In contrast to a model-based approach, the current study presents a data-driven detailed statistical procedure for estimating total seroprevalence (defined as antibodies from natural infection or from full vaccination) in a region using prospectively collected serological data and state-level vaccination data. Specifically, we conducted a longitudinal statewide serological survey with 88,605 participants 5 years or older with 3 prospective blood draws beginning …

Predictors Of E-Cigarette Initiation And Use Among Middle School Youth In A Low-Income Predominantly Hispanic Community, M Yvonne Gaddy, Denise Vasquez, Louis D Brown

Faculty, Staff and Student Publications

Introduction: E-cigarette use among middle and high school youth increased from 2. 5 million in 2014 to 9.2 million in 2019, becoming the most common tobacco product used among youth. Hispanic youth, the largest ethnic minority in the United States, have higher rates of tobacco use, including e-cigarettes, than non-Hispanics. Identifying factors that put youth at risk for future e-cigarette use is vital to focusing prevention efforts. Informed by social cognitive theory, this study identifies predictors of e-cigarette uptake among e-cigarette naïve youth in a predominantly low-income Hispanic community.

Methods: 1,249 students (6-8th grades) from two middle schools in El …
