The ongoing concurrent outbreaks of Zika, Chikungunya, and dengue viruses in Latin America and the Caribbean highlight the need for development of broad-spectrum antiviral treatments. The type I interferon (IFN) system has evolved in vertebrates to generate tissue responses that actively block replication of multiple known and potentially zoonotic viruses. As such, its control and activation through pharmacological agents may represent a novel therapeutic strategy for simultaneously impairing growth of multiple virus types and rendering host populations resistant to virus spread. In light of this strategy's potential, we undertook a screen to identify novel interferon-activating small molecules. Here, we describe …

A Lung Cancer Risk Classifier Comprising Genome Maintenance Genes Measured In Normal Bronchial Epithelial Cells, Jiyoun Yeo, Erin L. Crawford, Xiaolu Zhang, Sadik Khuder, Tian Chen, Albert M. Levin, Thomas M. Blomquist, James C. Willey

Public Health Sciences Articles

BACKGROUND: Annual low dose CT (LDCT) screening of individuals at high demographic risk reduces lung cancer mortality by more than 20%. However, subjects selected for screening based on demographic criteria typically have less than a 10% lifetime risk for lung cancer. Thus, there is need for a biomarker that better stratifies subjects for LDCT screening. Toward this goal, we previously reported a lung cancer risk test (LCRT) biomarker comprising 14 genome-maintenance (GM) pathway genes measured in normal bronchial epithelial cells (NBEC) that accurately classified cancer (CA) from non-cancer (NC) subjects. The primary goal of the studies reported here was to …

Sensory Processing In Autism Spectrum Disorders And Fragile X Syndrome-From The Clinic To Animal Models., D Sinclair, B Oranje, K A Razak, S J Siegel, S Schmid

Brain and Mind Institute Researchers' Publications

Brains are constantly flooded with sensory information that needs to be filtered at the pre-attentional level and integrated into endogenous activity in order to allow for detection of salient information and an appropriate behavioral response. People with Autism Spectrum Disorder (ASD) or Fragile X Syndrome (FXS) are often over- or under-reactive to stimulation, leading to a wide range of behavioral symptoms. This altered sensitivity may be caused by disrupted sensory processing, signal integration and/or gating, and is often being neglected. Here, we review translational experimental approaches that are used to investigate sensory processing in humans with ASD and FXS, and …

Online Neural Monitoring Of Statistical Learning., Laura J Batterink, Ken A Paller

Brain and Mind Institute Researchers' Publications

The extraction of patterns in the environment plays a critical role in many types of human learning, from motor skills to language acquisition. This process is known as statistical learning. Here we propose that statistical learning has two dissociable components: (1) perceptual binding of individual stimulus units into integrated composites and (2) storing those integrated representations for later use. Statistical learning is typically assessed using post-learning tasks, such that the two components are conflated. Our goal was to characterize the online perceptual component of statistical learning. Participants were exposed to a structured stream of repeating trisyllabic nonsense words and a …

Sex-Specific Associations Of Maternal Birthweight With Offspring Birthweight In The Omega Study., Collette N Ncube, Amelia R Gavin, Michelle A Williams, Chunfang Qiu, Tanya K Sorensen, Daniel A Enquobahrie

Articles, Abstracts, and Reports

PURPOSE: We investigated nonlinear and offspring sex-specific associations of maternal birthweight (BW) with offspring BW among participants of the Omega study, a pregnancy cohort.

METHODS: Maternal BW was modeled as a continuous variable, linear spline and binary variable indicating low birthweight (LBW;≥2500 grams). Offspring BW was modeled as a continuous and binary variable in regression models. Nonlinearity was assessed using likelihood ratio tests (LRTs) in marginal linear spline models.

RESULTS: For every 100-gram increase of maternal BW, offspring BW increased by 22.29 (95% CI: 17.57, 27.02) or 23.41 (95% CI: 6.87, 39.96) grams among mothers with normal BW or born …

Sigma1 Targeting To Suppress Aberrant Androgen Receptor Signaling In Prostate Cancer., Jeffrey D. Thomas, Charles G. Longen, Halley M. Oyer, Nan Chen, Christina M. Maher, Joseph M. Salvino, Blase Kania, Kelsey N. Anderson, William F. Ostrander, Karen E. Knudsen, Felix J. Kim

Department of Cancer Biology Faculty Papers

Suppression of androgen receptor (AR) activity in prostate cancer by androgen depletion or direct AR antagonist treatment, although initially effective, leads to incurable castration-resistant prostate cancer (CRPC) via compensatory mechanisms including resurgence of AR and AR splice variant (ARV) signaling. Emerging evidence suggests that Sigma1 (also known as sigma-1 receptor) is a unique chaperone or scaffolding protein that contributes to cellular protein homeostasis. We reported previously that some Sigma1-selective small molecules can be used to pharmacologically modulate protein homeostasis pathways. We hypothesized that these Sigma1-mediated responses could be exploited to suppress AR protein levels and activity. Here we demonstrate that …

Contextual Factors And Sexual Risk Behaviors Among Young, Black Men, Jamal Jones, Laura F. Salazar, Richard A. Crosby

Health, Behavior & Society Faculty Publications

Young Black men (YBM), aged 13 to 24 years, face a disproportionate burden of sexually transmitted infections (STIs). STI acquisition among YBM is due to incorrect and inconsistent condom use and is exacerbated by multiple sexual partners. Sexual and reproductive health is influenced by a complex interaction of biological, psychological, and social determinants that contribute to increased risk for STI acquisition. However, there are key social determinants of sexual health that play a major role in adolescent sexual risk-taking behaviors: gender norms, environment, peers, and families as well as a desire to impregnate a woman. Associations between contextual factors (risky …

The Acttion-Aps-Aapm Pain Taxonomy (Aaapt) Multidimensional Approach To Classifying Acute Pain Conditions., Michael L Kent, Patrick J Tighe, Inna Belfer, Timothy J Brennan, Stephen Bruehl, Chad M Brummett, Chester C Buckenmaier, Asokumar Buvanendran, Robert I Cohen, Paul Desjardins, David Edwards, Roger Fillingim, Jennifer Gewandter, Debra B Gordon, Robert W Hurley, Henrik Kehlet, John D Loeser, Sean Mackey, Samuel A Mclean, Rosemary Polomano, Siamak Rahman, Srinivasa Raja, Michael Rowbotham, Santhanam Suresh, Bernard Schachtel, Kristin Schreiber, Mark Schumacher, Brett Stacey, Steven P Stanos, Knox Todd, Dennis C Turk, Steven J Weisman, Christopher Wu, Daniel B Carr, Robert H Dworkin, Gregory Terman

Articles, Abstracts, and Reports

Objective: With the increasing societal awareness of the prevalence and impact of acute pain, there is a need to develop an acute pain classification system that both reflects contemporary mechanistic insights and helps guide future research and treatment. Existing classifications of acute pain conditions are limiting, with a predominant focus on the sensory experience (e.g., pain intensity) and pharmacologic consumption. Consequently, there is a need to more broadly characterize and classify the multidimensional experience of acute pain.

Articles, Abstracts, and Reports

BACKGROUND AND PURPOSE: ADC as a marker of tumor cellularity has been promising for evaluating the response to therapy in patients with glioblastoma but does not successfully stratify patients according to outcomes, especially in the upfront setting. Here we investigate whether restriction spectrum imaging, an advanced diffusion imaging model, performed after an operation but before radiation therapy, could improve risk stratification in patients with newly diagnosed glioblastoma relative to ADC.

MATERIALS AND METHODS: Pre-radiation therapy diffusion-weighted and structural imaging of 40 patients with glioblastoma were examined retrospectively. Restriction spectrum imaging and ADC-based hypercellularity volume fraction (restriction spectrum imaging-FLAIR volume fraction, …

Application Of Fluoroquinolone Resistance Score In Management Of Complicated Urinary Tract Infections, Ansal Shah, Julie Ann Justo, P Brandon Bookstaver, Joseph Kohn, Helmut Albrecht, Majdi N. Al-Hasan

Faculty Publications

The fluoroquinolone resistance score (FQRS) predicts the probability of fluoroquinolone resistance with good discrimination. The score has been derived from patients with bloodstream infections caused by Gram-negative bacteria and is based on fluoroquinolone use within the past 6 months, among other clinical and health care exposure criteria. This study aims to examine the utility of the FQRS in patients with complicated urinary tract infections (cUTI) and determine whether extension of prior fluoroquinolone use to 12 months improves model discrimination. Adults with cUTI at Palmetto Health in central South Carolina, USA, from 1 April 2015 through 31 July 2015 were prospectively …

Tuberculosis And Risk Of Acute Myocardial Infarction: A Propensity Score-Matched Analysis, Moises A. Huaman, Richard J. Kryscio, Carl J. Fichtenbaum, David Henson, Elizabeth G. Salt, Timothy R. Sterling, Beth A. Garvy

Biostatistics Faculty Publications

Several pathogens have been associated with increased cardiovascular disease (CVD) risk. Whether this occurs with Mycobacterium tuberculosis infection is unclear. We assessed if tuberculosis disease increased the risk of acute myocardial infarction (AMI). We identified patients with tuberculosis index claims from a large de-identified database of ~15 million adults enrolled in a U.S. commercial insurance policy between 2008 and 2010. Tuberculosis patients were 1:1 matched to patients without tuberculosis claims using propensity scores. We compared the occurrence of index AMI claims between the tuberculosis and non-tuberculosis cohorts using Kaplan–Meier curves and Cox Proportional Hazard models. Data on 2026 patients with …

A Pilot Investigation Of Acute Inhibitory Control Training In Cocaine Users, Joseph L. Alcorn, Erika Pike, William W. Stoops, Joshua A. Lile, Craig R. Rush

Behavioral Science Faculty Publications

Background—Disrupted response inhibition and presence of drug-cue attentional bias in cocaine-using individuals have predicted poor treatment outcomes. Inhibitory control training could help improve treatment outcomes by strengthening cognitive control. This pilot study assessed the effects of acute inhibitory control training to drug- and non-drug-related cues on response inhibition performance and cocaine-cue attentional bias in cocaine-using individuals.

Methods—Participants who met criteria for a cocaine-use disorder underwent five sessions of inhibitory control training to either non-drug-related cues (i.e., rectangles) or cocaine cues (n=10/condition) in a single day. Response inhibition and attentional bias were assessed prior to and following training using …

Odd Symptom Network During Preschool, Tess E. Smith, Christine A. Lee, Michelle M. Martel, Marni E. Axelrad

Psychology Faculty Publications

Several different conceptualizations of Oppositional Defiant Disorder (ODD) symptoms have been proposed, including one undivided set of symptoms (DSM-IV-TR; APA 2000); two domains of symptoms subdivided into affective and behavioral; and three domains of symptoms subdivided as angry/irritable, argumentative/defiant, and spiteful. The current study utilizes a novel approach to examining the division of ODD symptoms through use of network analysis. Participants were 109 preschoolers (64 male) between the ages of three and six (M = 4.34 years, SD = 1.08) and their parents and teachers/caregivers, who provided ratings of ODD symptoms. Results are consistent with one-, two-, and three- …

The Interactive Effect Of Diabetes Family Conflict And Depression On Insulin Bolusing Behaviors For Youth., Genevieve Maliszewski, Susana R. Patton, L Kurt Midyett, Mark A. Clements

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Adherence to type 1 diabetes management declines as children enter adolescence. For youth, psychosocial variables including mood and interpersonal relationships play a large role in diabetes maintenance. The current study assessed the unique and interactive roles diabetes family conflict and depression have on insulin bolusing behaviors for youth ages 10-16 years.

METHODS: Ninety-one youth-parent dyads completed a survey assessing family conflict and depression. Mean daily blood glucose levels, mealtime insulin bolus scores ( BOLUS), and glycated hemoglobin (HbA1c) were collected from the medical record as outcome variables.

RESULTS: Parent-reported diabetes-related family conflict and youths' endorsed depression both significantly predicted …

Role Of Biomechanical Forces In Hyperfiltration-Mediated Glomerular Injury In Congenital Anomalies Of The Kidney And Urinary Tract., Tarak Srivastava, Ganesh Thiagarajan, Uri S. Alon, Ram Sharma, Ashraf El-Meanawy, Ellen T. Mccarthy, Virginia J. Savin, Mukut Sharma

Manuscripts, Articles, Book Chapters and Other Papers

Congenital anomalies of the kidney and urinary tract (CAKUT) including solitary kidney constitute the main cause of progressive chronic kidney disease (CKD) in children. Children born with CAKUT develop signs of CKD only during adolescence and do not respond to renin-angiotensin-aldosterone system blockers. Early cellular changes underlying CKD progression to end-stage renal disease by early adulthood are not well understood. The mechanism of maladaptive hyperfiltration that occurs from loss of functional nephrons, including solitary kidney, is not clear. We re-examine the phenomenon of hyperfiltration in the context of biomechanical forces with special reference to glomerular podocytes. Capillary stretch exerts tensile …

The objective of this study was to assess the association between previous antibiotic use, particularly long-term prophylaxis, and the occurrence of subsequent resistant infections in children with index infections due to extended-spectrum-cephalosporin-resistant Enterobacteriaceae We also investigated the concordance of the index and subsequent isolates. Extended-spectrum-cephalosporin-resistant Escherichia coli and Klebsiella spp. isolated from normally sterile sites of patients aged species, resistance determinants, and fumC-fimH (E. coli) or tonB (Klebsiella pneumoniae) type were identical to those of the index isolate. In total, 323 patients had 396 resistant isolates; 45 (14%) patients had ≥1 subsequent resistant infection, totaling 73 …

Substance Use, Treatment, And Demographic Characteristics Of Pregnant Women Entering Treatment For Opioid Use Disorder Differ By United States Census Region., Dennis J Hand, Vanessa L Short, Diane J Abatemarco

Department of Obstetrics and Gynecology Faculty Papers

Opioid use disorder (OUD) among pregnant women increased substantially between 1992 and 2012 across the United States, with the greatest increases occurring in the southern states. We analyzed the 2013 Treatment Episodes Database-Admissions to determine how substances used, characteristics of treatment, and demographics of pregnant women entering treatment for opioid use disorder vary between geographical regions. Analyses were restricted to cases where women reported being pregnant at the time of admission and reported opioids as the primary substance problem leading to the treatment admission. Characteristics were compared between U.S. census regions using Chi-square tests and logistic regression with the South …

The North American Association of Central Cancer Registries (NAACCR) collects population-based data from 55 cancer registries throughout U.S. and Canada. All invasive primary (i.e. non-metastatic tumors), with age at diagnosis 0–19 years old, were included. Nearly 27,000 and 2200 central nervous system (CNS) tumors from non-Appalachia and Appalachia, respectively comprise the cohorts. Age-adjusted incidence rates of each main brain tumor subtype were compared. The incidence rate of pediatric CNS …

Paracrine Regulation Of Melanocyte Genomic Stability: A Focus On Nucleotide Excision Repair, Stuart Gordon Jarrett, Katharine Marie Carter, John August D'Orazio

Markey Cancer Center Faculty Publications

UV radiation is a major environmental risk factor for the development of melanoma by causing DNA damage and mutations. Resistance to UV damage is largely determined by the capacity of melanocytes to respond to UV injury by repairing mutagenic photolesions. The nucleotide excision repair (NER) pathway is the major mechanism by which cells correct UV photodamage. This multistep process involves the basic steps of damage recognition, isolation, localized strand unwinding, assembly of a repair complex, excision of the damage‐containing strand 3′ and 5′ to the photolesion, synthesis of a sequence‐appropriate replacement strand, and finally ligation to restore continuity of genomic …
