Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.

A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment.

Twenty nine percent of patients were not immunosuppressed. Histoplasma antigen, or anti-Histoplasma antibodies were detected in the …

PURPOSE: To evaluate the effects of eslicarbazepine acetate (ESL) on lipid metabolism and to determine whether reduced statin exposure during ESL therapy has clinical consequences.

SUBJECTS AND METHODS: We conducted a post-hoc analysis of pooled data for serum lipids (laboratory values) from three phase III, multicenter, randomized, double-blind, placebo-controlled trials of adjunctive ESL therapy (400, 800, or 1200 mg once daily) in patients with treatment-refractory partial-onset seizures. Changes from baseline in serum lipid levels were analyzed according to use of statins and/or enzyme-inducing antiepileptic drugs (EIAEDs) during the baseline period.

KEY FINDINGS: In total, 426 and 1021 placebo- and ESL-treated …

Ebola Virus Localization In The Macaque Reproductive Tract During Acute Ebola Virus Disease., Donna L. Perry, Louis M. Huzella, John G. Bernbaum, Michael R. Holbrook, Peter B. Jahrling, Katie R. Hagen, Matthias J. Schnell, Reed F. Johnson

Department of Microbiology and Immunology Faculty Papers

Sexual transmission of Ebola virus (EBOV) has been demonstrated more than a year after recovery from the acute phase of Ebola virus disease (EVD). The mechanisms underlying EBOV persistence and sexual transmission are not currently understood. Using the acute macaque model of EVD, we hypothesized EBOV would infect the reproductive tissues and sought to localize the infection in these tissues using immunohistochemistry and transmission electron microscopy. In four female and eight male macaques that succumbed to EVD between 6 and 9 days after EBOV challenge, we demonstrate widespread EBOV infection of the interstitial tissues and endothelium in the ovary, uterus, …

Pascale, Alejandra Martinez Lege, Dale Ding, Nohra Chalouhi, David M. Hasan, Pascal Jabbour, Gary K Owens, Michal Toborek, Joshua M. Hare, Aaron S. Dumont

Department of Neurosurgery Faculty Papers

OBJECTIVE: Cigarette smoke exposure (CSE) is a risk factor for cerebral aneurysm (CA) formation, but the molecular mechanisms are unclear. Although CSE is known to contribute to excess reactive oxygen species generation, the role of oxidative stress on vascular smooth muscle cell (VSMC) phenotypic modulation and pathogenesis of CAs is unknown. The goal of this study was to investigate whether CSE activates a NOX (NADPH oxidase)-dependent pathway leading to VSMC phenotypic modulation and CA formation and rupture.

APPROACH AND RESULTS: In cultured cerebral VSMCs, CSE increased expression of NOX1 and reactive oxygen species which preceded upregulation of proinflammatory/matrix remodeling genes …

Patient And Hospital Characteristics Predictive Of Inferior Vena Cava Filter Usage In Venous Thromboembolism Patients: A Study From The 2013 To 2014 Nationwide Readmissions Database, Amie Goodin, Ming Chen, Driss Raissi, Qiong Han, Hong Xiao, Joshua Brown

Radiology Faculty Publications

To examine the association between patient and hospital characteristics and inferior vena cava filter (IVCF) utilization in patients with venous thromboembolism (VTE).

The 2013 to 2014 Nationwide Readmissions Database was used to define a cohort of patients with VTE aged ≥ 18 after a primary VTE diagnosis. Comorbidities of interest were classified via diagnosis codes and IVCF placement was identified via procedure code. Chi square analysis tested differences between patient and hospital-level characteristics and whether or not IVCFs were placed. A hierarchical logistic regression model estimated the relationship between patient-level factors (demographics, socioeconomic status, comorbidities), hospital-level factors (bed size, teaching …

Examining 20 730 individuals, we report a molecular genetics-based heritability estimate (h

The Long-Term Effect Of Erythropoiesis Stimulating Agents Given To Preterm Infants: A Proton Magnetic Resonance Spectroscopy Study On Neurometabolites In Early Childhood, Charles Gasparovic, Arvind Caprihan, Ronald A Yeo, John Phillips, Jean R Lowe, Richard Campbell, Robin K Ohls

Pediatrics Research and Scholarship

BACKGROUND: Erythropoiesis stimulating agents (ESAs) are neuroprotective in cell and animal models of preterm birth. Prematurity has been shown to alter neurometabolite levels in children in studies using proton magnetic resonance spectroscopy (1H-MRS).

OBJECTIVE: We hypothesized that ESA treatment in premature infants would tend to normalize neurometabolites by 4-6 years of age.

MATERIALS AND METHODS: Children in a longitudinal study of neurodevelopment underwent MRI and 1H-MRS at approximately 4 years and 6 years of age. Prematurely born children (500-1,250 g birth weight) received ESAs (erythropoietin or darbepoetin) or placebo during their neonatal hospitalization, and these groups were compared to healthy …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Many HIV-affected couples living in sub-Saharan Africa desire to have children, but few quantitative studies have examined support for their childbearing needs. Our study explored client-provider communication about childbearing and safer conception among HIV clients in Uganda.

METHODS: 400 Ugandan HIV clients in committed relationships and with intentions to conceive were surveyed. Knowledge, attitudes and practices related to childbearing, and use of safer conception methods were assessed, including communication with providers about childbearing needs, the correlates of which were examined with bivariate statistics and logistic multivariate analysis.

RESULTS: 75% of the sample was female; 61% were on antiretroviral therapy; …

Modified Single Prolonged Stress Reduces Cocaine Self-Administration During Acquisition Regardless Of Rearing Environment, Rebecca S. Hofford, Mark A. Prendergast, Michael T. Bardo

Psychology Faculty Publications

Until recently, there were few rodent models available to study the interaction of post-traumatic stress disorder (PTSD) and drug taking. Like PTSD, single prolonged stress (SPS) produces hypothalamic-pituitary-adrenal (HPA) axis dysfunction and alters psychostimulant self-administration. Other stressors, such as isolation stress, also alter psychostimulant self-administration. However, it is currently unknown if isolation housing combined with SPS can alter the acquisition or maintenance of cocaine self-administration. The current study applied modified SPS (modSPS; two hours restraint immediately followed by cold swim stress) to rats raised in an isolation condition (Iso), enrichment condition (Enr), or standard condition (Std) to measure changes in …

Nmda Receptor Blockade Specifically Impedes The Acquisition Of Incentive Salience Attribution, Jonathan J. Chow, Joshua S. Beckmann

Psychology Faculty Publications

Glutamatergic signaling plays an important role in learning and memory. Using Pavlovian conditioned approach procedures, the mechanisms that drive stimulus-reward learning and memory have been investigated. However, there are instances where reward-predictive stimuli can function beyond being solely predictive and can be attributed with “motivational value” or incentive salience. Using a Pavlovian conditioned approach procedure consisting of two different but equally predictive stimuli (lever vs. tone) we investigated the role NMDA receptor function has in the attribution of incentive salience. The results revealed that the administration of MK-801, an NMDA receptor antagonist, during acquisition of Pavlovian conditioned approach promoted goal-tracking …

Tnf Receptor-Activated Factor 2 Mediates Cardiac Protection Through Noncanonical Nf-Κb Signaling, Sarah Evans, Huei-Ping Tzeng, Deborah J Veis, Scot Matkovich, Carla Weinheimer, Attila Kovacs, Philip M Barger, Douglas L Mann

Open Access Publications

To elucidate the mechanisms responsible for cytoprotective effects of TNF receptor-activated factor 2 (TRAF2) in the heart, we employed genetic gain- and loss-of-function studies ex vivo and in vivo in mice with cardiac-restricted overexpression of TRAF2 (Myh6-TRAF2LC). Crossing Myh6-TRAF2LC mice with mice lacking canonical signaling (Myh6-TRAF2LC/Myh6-IκBαΔN) abrogated the cytoprotective effects of TRAF2 ex vivo. In contrast, inhibiting the JAK/STAT pathway did not abrogate the cytoprotective effects of TRAF2. Transcriptional profiling of WT, Myh6-TRAF2LC, and Myh6-TRAF2LC/Myh6-IκBαΔN mouse hearts suggested that the noncanonical NF-κB signaling pathway was upregulated in the Myh6-TRAF2LC mouse hearts. Western blotting and ELISA for the NF-κB family proteins …

Scope: Body weight responds variably to the intake of dairy foods. Genetic variation may contribute to inter‐individual variability in associations between body weight and dairy consumption.

Methods and results: A genome‐wide interaction study to discover genetic variants that account for variation in BMI in the context of low‐fat, high‐fat and total dairy intake in cross‐sectional analysis was conducted. Data from nine discovery studies (up to 25 513 European descent individuals) were meta‐analyzed. Twenty‐six genetic variants reached the selected significance threshold (p‐interaction <10⁻⁷⁾, and six independent variants (LINC01512‐rs7751666, PALM2/AKAP2‐rs914359, ACTA2‐rs1388, PPP1R12A‐rs7961195, LINC00333‐rs9635058, …

Interaction Between Pre-Treatment Drug Use And Heterogeneity Of Psychiatric Diagnosis Predicts Outcomes In Outpatients With Co-Occurring Disorders., Oladunni Oluwoye, Katherine Hirchak, Emily Leickly, Jordan Skalisky, Sterling M Mcpherson, Debra Srebnik, John M Roll, Richard K Ries, Michael G Mcdonell

Articles, Abstracts, and Reports

We examined whether the interaction of baseline stimulant use, assessed by urine drug tests, and type of serious mental illness (SMI) diagnosis predicted stimulant use in a trial of contingency management (CM). The interaction between baseline stimulant use and SMI diagnoses was significant in the overall sample (p=0.002) when controlling for the main effects of treatment condition, baseline stimulant use, and SMI diagnosis. Similar results were also found within the CM sample. Individuals with bipolar disorder were more or less likely, depending on their baseline stimulant-drug test results, to use stimulants during treatment compared to those with other SMI diagnoses.

Treated Hypothyroidism Is Associated With Cerebrovascular Disease But Not Alzheimer's Disease Pathology In Older Adults, Willa D. Brenowitz, Fang Han, Walter A. Kukull, Peter T. Nelson

Pathology and Laboratory Medicine Faculty Publications

Thyroid hormone (TH) disease is common among older adults and is associated with cognitive impairment. However, pathologic correlates are not well understood. We studied pathologic and clinical factors associated with hypothyroidism, the most common form of TH disease, in research subjects seen annually for clinical evaluations at U.S. Alzheimer’s Disease Centers. Thyroid disease and treatment status were assessed during clinician interviews. Among autopsied subjects, there were 555 participants with treated hypothyroidism and 2,146 with no known thyroid disease; hypothyroidism was associated with severe atherosclerosis (OR=1.35 95% CI: 1.02, 1.79) but not Alzheimer’s disease (AD) pathologies (amyloid plaques or neurofibrillary tangles). …

Development Of Body Emotion Perception In Infancy: From Discrimination To Recognition, Alison Heck, Alyson Chroust, Hannah B. White, Rachel Lynn Jubran, Ramesh S. Bhatt

Psychology Faculty Publications

Research suggests that infants progress from discrimination to recognition of emotions in faces during the first half year of life. It is unknown whether the perception of emotions from bodies develops in a similar manner. In the current study, when presented with happy and angry body videos and voices, 5-month-olds looked longer at the matching video when they were presented upright but not when they were inverted. In contrast, 3.5-month-olds failed to match even with upright videos. Thus, 5-month-olds but not 3.5-month-olds exhibited evidence of recognition of emotions from bodies by demonstrating intermodal matching. In a subsequent experiment, younger infants …

Visual Scanning Of Males And Females In Infancy, Hannah B. White, Alyson J. Hock, Rachel L. Jubran, Alison Heck, Ramesh S. Bhatt

Psychology Faculty Publications

This study addressed the development of attention to information that is socially relevant to adults by examining infants' (n = 64) scanning patterns of male and female bodies. Infants exhibited systematic attention to regions associated with sex-related scanning by adults, with 3.5-and 6.5-month-olds looking longer at the torso of females than males and longer at the legs of males than females. However, this pattern of looking was not found when infants were tested on headless bodies in Experiment 2, which suggests that infants' differential gaze pattern in Experiment 1 was not due to low-level stimulus features, such as clothing, and …

RESULTS: A total of 46 patients received GC4419 in 11 separate dosing and duration cohorts: dose escalation occurred in 5 cohorts receiving 15 to 112 mg/d over 3 weeks (n=20), duration escalation in …

Use Of Self-Management Interventions For Chronic Pain Management: A Comparison Between Rural And Nonrural Residents, Linda H Eaton, Dale J Langford, Alexa R Meins, Tessa Rue, David J Tauben, Ardith Z Doorenbos

Project ECHO Bibliography

Individuals with chronic pain who live in rural communities often lack access to pain specialists and rely on primary care providers who may be less prepared. Research has indicated that rural residents with chronic pain are more likely to receive an opioid prescription than nonrural residents. Although self-management approaches are available for chronic pain management, it is unclear to what extent rural residents use these interventions. This study compares usage of self-management interventions and opioid-based analgesics for chronic pain management between rural and nonrural residents. This study is a secondary analysis of baseline data from a randomized controlled trial evaluating …

Kruppel-Like Factor 4-Dependent Staufen1-Mediated Mrna Decay Regulates Cortical Neurogenesis, Byoung-San Moon, Jinlun Bai, Mingyang Cai, Chunming Liu, Jiandang Shi, Wange Lu

Molecular and Cellular Biochemistry Faculty Publications

Kruppel-like factor 4 (Klf4) is a zinc-finger-containing protein that plays a critical role in diverse cellular physiology. While most of these functions attribute to its role as a transcription factor, it is postulated that Klf4 may play a role other than transcriptional regulation. Here we demonstrate that Klf4 loss in neural progenitor cells (NPCs) leads to increased neurogenesis and reduced self-renewal in mice. In addition, Klf4 interacts with RNA-binding protein Staufen1 (Stau1) and RNA helicase Ddx5/17. They function together as a complex to maintain NPC self-renewal. We report that Klf4 promotes Stau1 recruitment to the 3′-untranslated region of neurogenesis-associated mRNAs, …

Zinc Inhibits Trpv1 To Alleviate Chemotherapy-Induced Neuropathic Pain, Jialie Luo, Alexis Bavencoffe, Pu Yang, Jing Feng, Shijin Yin, Aihua Qian, Weihua Yu, Shenbin Liu, Xuan Gong, Tao Cai, Edgar T. Walters, Carmen W. Dessauer, Hongzhen Hu

Open Access Publications

Zinc is a transition metal that has a long history of use as an anti-inflammatory agent. It also soothes pain sensations in a number of animal models. However, the effects and mechanisms of zinc on chemotherapy-induced peripheral neuropathy remain unknown. Here we show that locally injected zinc markedly reduces neuropathic pain in male and female mice induced by paclitaxel, a chemotherapy drug, in a TRPV1-dependent manner. Extracellularly applied zinc also inhibits the function of TRPV1 expressed in HEK293 cells and mouse DRG neurons, which requires the presence of zinc-permeable TRPA1 to mediate entry of zinc into the cytoplasm. Moreover, TRPA1 …
