Faculty, Staff and Student Publications

BACKGROUND: While there is significant research exploring adults' use of opioids, there has been minimal focus on the opioid impact within emergency departments for the pediatric population.

METHODS: We examined data from the Agency for Healthcare Research, the National Emergency Department Sample (NEDS), and death data from the Centers for Disease Control and Prevention. Sociodemographic and financial variables were analyzed for encounters during 2014-2017 for patients under age 18, matching diagnoses codes for opioid-related overdose or opioid use disorder.

RESULTS: During this period, 59,658 children presented to an ED for any diagnoses involving opioids. The majority (68.5%) of visits were …

Repurposing Probenecid For The Treatment Of Heart Failure (Re-Prosper-Hf): A Study Protocol For A Randomized Placebo-Controlled Clinical Trial, Jack Rubinstein, Nathan Robbins, Karen Evans, Gabrielle Foster, Kevin Mcconeghy, Toluwalope Onadeko, Julie Bunke, Melanie Parent, Xi Luo, Jacob Joseph, Wen-Chih Wu

BACKGROUND: Improving contractility in heart failure with reduced ejection fraction (HFrEF) has resurfaced as a potential treatment goal. Inotropic therapy is now better understood through its underlying mechanism as opposed to the observed effect of increasing contractility. Calcitropes are a subgroup of inotropes that largely depend on the stimulation of adenylyl cyclase to transform ATP into cyclic adenosine monophosphate (cAMP). At least two clinically relevant calcitropes-istaroxime and probenecid-improve contractility through an increase in systolic intracellular calcium without activating cAMP production. Probenecid, which has been safely used clinically for decades in non-cardiac conditions, has recently been identified as an agonist of …

Background: Functional recovery of arm movement typically plateaus following a stroke, leaving chronic motor deficits. Brain-computer interfaces (BCI) may be a potential treatment for post-stroke deficits

Methods: In this n-of-1 trial (NCT03913286), a person with chronic subcortical stroke with upper-limb motor impairment used a powered elbow-wrist-hand orthosis that opened and closed the affected hand using cortical activity, recorded from a percutaneous BCI comprised of four microelectrode arrays implanted in the ipsilesional precentral gyrus, based on decoding of spiking patterns and high frequency field potentials generated by imagined hand movements. The system was evaluated in a home setting for 12 weeks …

TIAM Rac1-associated GEF 1 (TIAM1) regulates RAC1 signaling pathways that affect the control of neuronal morphogenesis and neurite outgrowth by modulating the actin cytoskeletal network. To date, TIAM1 has not been associated with a Mendelian disorder. Here, we describe five individuals with bi-allelic TIAM1 missense variants who have developmental delay, intellectual disability, speech delay, and seizures. Bioinformatic analyses demonstrate that these variants are rare and likely pathogenic. We found that the Drosophila ortholog of TIAM1, still life (sif), is expressed in larval and adult central nervous system (CNS) and is mainly expressed in a subset of neurons, but not in …

Post-Intensive Care Syndrome Prevention And Detection In Covid-19 Patients, Bethany Sloane Melega

Student Scholar Showcase

COVID-19 has impacts on patient health beyond the hospital. The trauma that patients, and families of patients, can experience during an admission to an intensive care unit (ICU) can last long after discharge from the ICU and the hospital in general. The psychological and physical impacts of ICU hospitalization can cause patients to experience Post Intensive Care Syndrome (PICS). PICS is the culmination of symptoms that persist after a critical illness that involve all aspects of a patient’s physical and mental well-being and can significantly affect family life and increase recovery time. Due to the strict personal-protective equipment (PPE) usage …

Hur Plays A Role In Double-Strand Break Repair In Pancreatic Cancer Cells And Regulates Functional Brca1-Associated-Ring-Domain-1(Bard1) Isoforms, Aditi Jain, Matthew Mccoy, Carolyn Coats, Samantha Z Brown, Sankar Addya, Carl Pelz, Rosalie C Sears, Charles Yeo, Jonathan R Brody

Department of Surgery Faculty Papers

Human Antigen R (HuR/ELAVL1) is known to regulate stability of mRNAs involved in pancreatic ductal adenocarcinoma (PDAC) cell survival. Although several HuR targets are established, it is likely that many remain currently unknown. Here, we identified BARD1 mRNA as a novel target of HuR. Silencing HuR caused a >70% decrease in homologous recombination repair (HRR) efficiency as measured by the double-strand break repair (pDR-GFP reporter) assay. HuR-bound mRNAs extracted from RNP-immunoprecipitation and probed on a microarray, revealed a subset of HRR genes as putative HuR targets, including the BRCA1-Associated-Ring-Domain-1 (BARD1) (p < 0.005). BARD1 genetic alterations are infrequent in PDAC, and its context-dependent upregulation is poorly understood. Genetic silencing (siRNA and CRISPR knock-out) and pharmacological targeting of HuR inhibited both full length (FL) BARD1 and its functional isoforms (α, δ, Φ). Silencing BARD1 sensitized cells to olaparib and oxaliplatin; caused G2-M cell cycle arrest; and increased DNA-damage while decreasing HRR efficiency in cells. Exogenous overexpression of BARD1 in HuR-deficient cells partially rescued the HRR dysfunction, independent of an HuR pro-oncogenic function. Collectively, our findings demonstrate for the first time that BARD1 is a bona fide HuR target, which serves as an important regulatory point of the transient DNA-repair response in PDAC cells.

Professional Quality Of Life In Respiratory Therapists: A Cross-Sectional Study Of The Prevalence And Predictors For Compassion Satisfaction, Burnout, And Secondary Traumatic Stress, Sarah Pehlke

Graduate Theses, Dissertations, and Capstones

Background: Research on professional quality of life (QOL) variables in healthcare providers proliferated following the onset of the COVID-19 pandemic. Evidence suggests that caregiving careers have positive and negative effects (Beck, 2011). Insufficient research describes these effects in respiratory therapists (RTs), a group of healthcare practitioners who often work in high-stress situations and provide care to high-acuity patient populations.

Purpose: This study evaluated the prevalence and predictors of professional QOL factors, compassion satisfaction (CS), burnout, and secondary traumatic stress (STS), in staff RTs in the United States.

Methods: RTs were invited to participate in a cross-sectional survey evaluating demographics, workplace …

Gestational Age Variation In Human Placental Drug Transporters, Laura Goetzl, Nune Darbinian, Nana Merabova, Lindsay C Devane, Sammanda Ramamoorthy

Faculty, Staff and Student Publications

Patient and providers' fear of fetal exposure to medications may lead to discontinuation of treatment, disease relapse, and maternal morbidity. Placental drug transporters play a critical role in fetal exposure through active transport but the majority of data are limited to the 3rd trimester, when the majority of organogenesis has already occurred. Our objective was to define gestational age (GA) dependent changes in protein activity, expression and modifications of five major placental drug transporters: SERT, P-gp, NET, BCRP and MRP3. Apical brush border membrane fractions were prepared from fresh 1st, 2nd and 3rd trimester human placentas collected following elective pregnancy …

Hsp90-Cdc37 Functions As A Chaperone For The Oncogenic Fgfr3-Tacc3 Fusion, Tao Li, Farideh Mehraein-Ghomi, M Elizabeth Forbes, Sanjeev V Namjoshi, E Ashley Ballard, Qianqian Song, Ping-Chieh Chou, Xuya Wang, Brittany C Parker Kerrigan, Frederick F Lang, Glenn Lesser, Waldemar Debinski, Xuejun Yang, Wei Zhang

The FGFR3-TACC3 (F3-T3) fusion gene was discovered as an oncogenic molecule in glioblastoma and bladder cancers, and has subsequently been found in many cancer types. Notably, F3-T3 was found to be highly expressed in both untreated and matched recurrence glioblastoma under the concurrent radiotherapy and temozolomide (TMZ) treatment, suggesting that targeting F3-T3 is a valid strategy for treatment. Here, we show that the F3-T3 protein is a client of heat shock protein 90 (HSP90), forming a ternary complex with the cell division cycle 37 (CDC37). Deprivation of HSP90 or CDC37 disrupts the formation of the ternary complex, which destabilizes glycosylated …

A Pilot Study To Examine The Effects Of Beta-Alanine And Sodium Citrate (Carnorushtm, Olimp®) Supplementation On Climbing-Specific Performance, Krzysztof Sas-Nowosielski, Piotr Kaczka

Baltic Journal of Health and Physical Activity

Introduction. Competitive and rock climbers primarily rely on anaerobic energy metabolism, and acidosis may limit their performance. It is supposed that supplements that improve buffering capacities of the body, like β-alanine (BA) and sodium bicarbonate/citrate (SB/SC), may be useful in this sport. The aim of the study was to explore the efficacy of co-supplementation of BA and SC on climbing performance. Material and methods. 13 climbers (age 40.2 ±7.9 years, height 175.4 ±8.4 cm, body mass 68.6 ±13.9 kg, UIAA metric 9.2 ±0.8) were randomly assigned to the supplement (SG; n = 7) or control group (CG: n = 6). …

Trigonella Foenum-Graecum Methanolic Extract On Isolated Smooth Muscles And Acetylcholinesterase Enzyme: An In Vitro And Mechanistic In Silico Investigation, Muhammad Nabeel Ghayur, Mohnad Abdalla, Asaad Khalid, Saeed Ahmad, Anwar Gilani

Department of Biological & Biomedical Sciences

Results: When tested on the baseline of isolated tissues, Tfg.Cr was devoid of any activity (stimulant or relaxant) till 10 mg/ml. This is an interesting finding, keeping in mind that the fenugreek seeds are used to alleviate constipation and diarrhoea. When Tfg.Cr was tried for any potential AChE inhibitory activity, it did show an inhibitory effect in increasing concentrations (47-380 μg/ml). This inhibitory effect was comparable to the effect produced by a standard AChE inhibitor physostigmine. One of the known fenugreek constituents, diosgenin, was also tested, and it also showed an AChE inhibitory effect in a concentration-dependent manner (11-190 …

Department of Medicine Faculty Papers

Background: Colchicine has been used an effective anti-inflammatory drug to treat gout diseases. Owing to its pharmacodynamic of inhibiting interleukins, it has been repurposed to target the cytokine storm post-SARS-CoV-2 invasion. The goal of this meta-analysis was to evaluate the safety profile of colchicine in COVID-19 patients using the gold-standard randomised-control trials.

Methods: Electronic databases (Pubmed, Google Scholar, and Cochrane) were systematically searched until June 2021 and RCTs were extracted. Outcomes of interest included all-cause mortality, COVID-19 severity, mechanical ventilation, C-reactive protein and D-dimer levels. Using a random-effects model, dichotomous outcomes were pooled using odds ratios (OR) through the generic …

Meloxicam Versus Celecoxib For Postoperative Analgesia After Total Knee Arthroplasty: Safety, Efficacy And Cost, Amer Haffar, Yale A Fillingham, Leigham Breckenridge, D'Andrew Gursay, Jess H Lonner

Rothman Institute Papers

INTRODUCTION: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used as part of multimodal analgesia in total knee arthroplasty (TKA). Selective cyclooxygenase (COX)-2 inhibitors (e.g., celecoxib) are believed to have fewer gastrointestinal (GI) adverse effects than nonselective NSAIDS. Meloxicam is less selective for COX-2 than celecoxib is and partially inhibits COX-1 at higher doses. Nonetheless, some surgeons prefer using nonselective NSAIDs because of their lower expense.

METHODS: Four thousand nine hundred ninety-four patients who underwent TKA between January 2015 and February 2020 and took either celecoxib (n = 3,174), meloxicam 15 mg/d (n = 1,819), or meloxicam 7.5 mg/d (n = 451) …

Genetic Evaluation For Hereditary Cancer Syndromes Among African Americans: A Critical Review, Ambreen Khan, Charles R Rogers, Carson D Kennedy, Ana Maria Lopez, Joanne Jeter

Department of Medical Oncology Faculty Papers

While hereditary cancer syndromes have been described and studied for centuries, the completion of the human genome project fueled accelerated progress in precision medicine due to the introduction of genetic testing in the 1990s, creating avenues for tailored treatments and medical management options. However, genetic testing has not benefited everyone equitably, with nearly all of the published work based on individuals of non-Hispanic White/European ancestry. There remains a gap in knowledge regarding the prevalence, penetrance, and manifestations of common hereditary cancer syndromes in the African-American population due to significant disparities in access and uptake of genetic testing. This review summarizes …

Targeting The Nrf2/Ho-1 Antioxidant Pathway In Flt3-Itd-Positive Aml Enhances Therapy Efficacy, Sankaranarayan Kannan, Mary E Irwin, Shelley M Herbrich, Tiewei Cheng, Lanisha L Patterson, Marisa J L Aitken, Kapil Bhalla, M James You, Marina Konopleva, Patrick A Zweidler-Mckay, Joya Chandra

Faculty, Staff and Student Publications

Acute myeloid leukemia (AML) is a molecularly heterogenous hematological malignancy, with one of the most common mutations being internal tandem duplication (ITD) of the juxtamembrane domain of the fms-like tyrosine kinase receptor-3 (FLT3). Despite the development of FLT3-directed tyrosine kinase inhibitors (TKI), relapse and resistance are problematic, requiring improved strategies. In both patient samples and cell lines, FLT3-ITD raises levels of reactive oxygen species (ROS) and elicits an antioxidant response which is linked to chemoresistance broadly in AML. NF-E2-related factor 2 (NRF2) is a transcription factor regulating the antioxidant response including heme oxygenase -1 (HO-1), a heat shock protein implicated …

Chronic Alcohol Exposure Induces Hepatocyte Damage By Inducing Oxidative Stress, Satb2 And Stem Cell-Like Characteristics, And Activating Lipogenesis, Wei Yu, Yiming Ma, Sushant K. Shrivastava, Rakesh K. Srivastava, Sharmila Shankar

School of Medicine Faculty Publications

Alcohol is a risk factor for hepatocellular carcinoma (HCC). However, the molecular mechanism by which chronic alcohol consumption contributes to HCC is not well understood. The purpose of the study was to demonstrate the effects of chronic ethanol exposure on the damage of human normal hepatocytes. Our data showed that chronic exposure of hepatocytes with ethanol induced changes similar to transformed hepatocytes that is, exhibited colonies and anchorage-independent growth. These damaged hepatocytes contained high levels of reactive oxygen species (ROS) and showed induction of the SATB2 gene. Furthermore, damaged hepatocytes gained the phenotypes of CSCs which expressed stem cell markers …

Csf-1 Maintains Pathogenic But Not Homeostatic Myeloid Cells In The Central Nervous System During Autoimmune Neuroinflammation, Daniel Hwang, Maryam S Seyedsadr, Larissa Ishikawa, Alexandra Boehm, Ziver Sahin, Giacomo Casella, Soohwa Jang, Michael V Gonzalez, James P Garifallou, Hakon Hakonarson, Weifeng Zhang, Dan Xiao, A M Rostami, Guang-Xian Zhang, Bogoljub Ciric

Department of Neurology Faculty Papers

SignificanceMultiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), are autoimmune diseases characterized by accumulation of myeloid cells in the central nervous system (CNS). Both harmful and beneficial myeloid cells are present in EAE/MS, and a goal of MS therapy is to preferentially remove harmful myeloid cells. The receptor for CSF-1 (CSF-1R) is found on myeloid cells and is important for their survival. CSF-1R can bind two ligands, CSF-1 and IL-34, but it is not known whether their functions in EAE/MS differ. We found that blocking CSF-1 depleted only harmful myeloid cells in the CNS and suppressed EAE, …

Faculty, Staff and Students Publications

Weight loss through behavioral modification is central to treating non-alcoholic fatty liver disease (NAFLD). To achieve this, patients need to accurately self-perceive their health behaviors. We aimed to identify predictors of concordance between self-perception and objective measures of body weight, physical activity (PA) and dietary behaviors. We used data from the Harris County NAFLD Cohort, an ongoing prospective study in a regional safety-net healthcare system. Patients completed self-administered baseline questionnaires on demographics, diet, PA, and self-perceptions. We assessed concordance between actual and self-perceived body weight and energy-balance behaviors. Multivariable logistic regression identified predictors of concordance. Patients (n = 458; average …

Making Waves: How Ultrasound-Targeted Drug Delivery Is Changing Pharmaceutical Approaches., Lauren J Delaney, Selin Isguven, John R Eisenbrey, Noreen J Hickok, Flemming Forsberg

Department of Radiology Faculty Papers

Administration of drugs through oral and intravenous routes is a mainstay of modern medicine, but this approach suffers from limitations associated with off-target side effects and narrow therapeutic windows. It is often apparent that a controlled delivery of drugs, either localized to a specific site or during a specific time, can increase efficacy and bypass problems with systemic toxicity and insufficient local availability. To overcome some of these issues, local delivery systems have been devised, but most are still restricted in terms of elution kinetics, duration, and temporal control. Ultrasound-targeted drug delivery offers a powerful approach to increase delivery, therapeutic …

Discharge Care Bundle To Reduce Copd 30-Day Readmission Rates In A Hospital Acute Care Unit, Dao Vang

Student Scholarly Projects

Practice Problem: Chronic obstructive pulmonary disease (COPD) readmissions severely impact patients’ health, mortality, and quality of life and increase unnecessary healthcare use and spending. Utilization of a protocol and discharge care bundle to reduce the readmission rate for COPD patients is critical to combat the problem.

Two-Dimensional Titanium Dioxide-Surfactant Photoactive Supramolecular Networks: Synthesis, Properties, And Applications For The Conversion Of Light Energy, Harold Lozano, Sindy Devis, Juan Aliaga, Matías Alegría, Hernán Guzmán, Roberto Villarroel, Eglantina Benavente, Guillermo González

Faculty, Staff and Students Publications

The desire to harness solar energy to address current global environmental problems led us to investigate two-dimensional (2D) core–shell hybrid photocatalysts in the form of a 2D-TiO2–surfactant, mainly composed of fatty acids. The bulk products, prepared by two slightly different methods, consist of stacked host–guest hybrid sheets held together by van der Waals forces between alkyl carboxylate moieties, favoring the synergistic conjugation of the photophysical properties of the core and the hydrophobicity of the self-assembled surfactant monolayer of the shell. X-ray diffraction and the vibrational characteristics of the products revealed the influence of synthesis strategies on two types of supramolecular …
