Bioprosthetic Aortic Valve Endocarditis In Association With Enterococcus Durans, Luca Fallavollita, Lorena Di Gioacchino, Fabrizio Balestrini

The Texas Heart Institute Journal

Enterococci are common organisms associated with endocarditis, but infection by Enterococcus durans is very rare. To our knowledge, only 3 cases have been reported in the medical literature, and all 3 have involved native valves. Here we publish the first reported case (to our knowledge) of E. durans endocarditis in association with a bioprosthetic aortic valve. After the organism and its antibiotic susceptibility were identified, the 74-year-old male patient was treated successfully with teicoplanin and gentamicin, over a course of 6 weeks.

Peripheral (Deep) But Not Periventricular Mri White Matter Hyperintensities Are Increased In Clinical Vascular Dementia Compared To Alzheimer's Disease, Charles D. Smith, Eleanor S. Johnson, Linda J. Van Eldik, Gregory A. Jicha, Frederick A. Schmitt, Peter T. Nelson, Richard J. Kryscio, Richard R. Murphy, Clinton V. Wellnitz

Neurology Faculty Publications

Background and purpose: Vascular dementia (VAD) is a complex diagnosis at times difficult to distinguish from Alzheimer's disease (AD). MRI scans often show white matter hyperintensities (WMH) in both conditions. WMH increase with age, and both VAD and AD are associated with aging, thus presenting an attribution conundrum. In this study, we sought to show whether the amount of WMH in deep white matter (dWMH), versus periventricular white matter (PVH), would aid in the distinction between VAD and AD, independent of age. Methods: Blinded semiquantitative ratings of WMH validated by objective quantitation of WMH volume from standardized MRI image acquisitions. …

Correlation Of Maximal Inspiratory Pressure To Transdiaphragmatic Twitch Pressure In Intensive Care Unit Patients, Gerald S. Supinski, Philip M. Westgate, Leigh Ann Callahan

Internal Medicine Faculty Publications

Background: Respiratory muscle weakness contributes to respiratory failure in ICU patients. Unfortunately, assessment of weakness is difficult since the most objective test, transdiaphragmatic pressure in response to phrenic nerve stimulation (PdiTw), is difficult to perform. While most clinicians utilize maximum inspiratory pressure (Pimax) to assess strength, the relationship of this index to PdiTw has not been evaluated in a large ICU population. The purpose of the present study was to assess both PdiTw and Pimax in ICU patients to determine how these indices correlate with each other, what factors influence these indices, and how well these indices predict outcomes.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease among children, the etiology of which involves a strong genetic component, but much of the underlying genetic determinants still remain unknown. Our aim was to identify novel genetic variants that predispose to JIA.

METHODS: We performed a genome-wide association study (GWAS) and replication in a total of 1166 JIA cases and 9500 unrelated controls of European ancestry. Correlation of SNP genotype and gene expression was investigated. Then we conducted targeted resequencing of a candidate locus, among a subset of 480 cases and 480 controls. SUM test was performed …

Where Are You Looking? Pseudogaze In Afterimages, Daw-An Wu, Patrick Cavanagh

Dartmouth Scholarship

How do we know where we are looking? A frequent assumption is that the subjective experience of our direction of gaze is assigned to the location in the world that falls on our fovea. However, we find that observers can shift their subjective direction of gaze among different nonfoveal points in an afterimage. Observers were asked to look directly at different corners of a diamond-shaped afterimage. When the requested corner was 3.5° in the periphery, the observer often reported that the image moved away in the direction of the attempted gaze shift. However, when the corner was at 1.75° eccentricity, …

When Is A Varicocele Repair Indicated: The Dilemma Of Hypogonadism And Erectile Dysfunction?, Ali A. Dabaja, Marc Goldstein

Urology Articles

In the past, the indications for varicocelectomy are primarily for infertility with abnormal semen parameters, testicular hypotrophy/atrophy in adolescents, and/or pain. The surgical treatment of varicocele for hypogonadism is controversial and debated. Recently, multiple reports in the literature have suggested that varicocele is associated with hypogonadism and varicocele repair can increase testosterone levels. Men with hypogonadal symptoms should have at least two serum testosterone levels. Microsurgical varicocelectomy may be beneficial for men with clinically palpable varicoceles with documented hypogonadism. In this review, we summarize the most recent literature linking varicocele to hypogonadism and sexual dysfunction and the impact of repair …

Molecular Analyses Of Circadian Gene Variants Reveal Sex-Dependent Links Between Depression And Clocks, S-Q Shi, M. J. White, H. M. Borsetti, Julie S. Pendergast, A. Hida, C. M. Ciarleglio, P. A. De Verteuil, A. G. Cadar, C. Cala, D. G. Mcmahon, R. C. Shelton, S. M. Williams, C. H. Johnson

Biology Faculty Publications

An extensive literature links circadian irregularities and/or sleep abnormalities to mood disorders. Despite the strong genetic component underlying many mood disorders, however, previous genetic associations between circadian clock gene variants and major depressive disorder (MDD) have been weak. We applied a combined molecular/functional and genetic association approach to circadian gene polymorphisms in sex-stratified populations of control subjects and case subjects suffering from MDD. This approach identified significant sex-dependent associations of common variants of the circadian clock genes hClock, hPer3 and hNpas2 with major depression and demonstrated functional effects of these polymorphisms on the expression or activity of the hCLOCK …

Fear Conditioning And Extinction In Youth With Obsessive-Compulsive Disorder, Joseph F. Mcguire, Scott P. Orr, Monica S. Wu, Adam B. Lewin, Brent J. Small, Vicky Phares, Tanya K. Murphy, Sabine Wilhelm, Daniel S. Pine, Daniel Geller, Eric A. Storch

Psychology Faculty Publications

BACKGROUND: Fear acquisition and extinction are central constructs in the cognitive-behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive-behavioral therapy (CBT). Youth with OCD may have impairments in fear acquisition and extinction that carry treatment implications. We examined these processes using a differential conditioning procedure.

METHODS: Forty-one youth (19 OCD, 22 community comparisons) completed a battery of clinical interviews, rating scales, and a differential conditioning task that included habituation, acquisition, and extinction phases. Skin conductance response (SCR) served as the primary dependent measure.

RESULTS: During habituation, no difference between groups was observed. During acquisition, differential fear conditioning was observed …

Multi-Level Correlates Of Safer Conception Methods Awareness And Attitudes Among Ugandan Hiv Clients With Fertility Intentions., Glenn J. Wagner, Mahlet A. Woldetsadik, Jolly Beyeza-Kashesya, Kathy Goggin, Deborah Mindry, Sarah Finocchario-Kessler, Sarah Khanakwa, Rhoda K. Wanyenze

Manuscripts, Articles, Book Chapters and Other Papers

Many people living with HIV desire childbearing, but low cost safer conception methods (SCM) such as timed unprotected intercourse (TUI) and manual self-insemination (MSI) are rarely used. We examined awareness and attitudes towards SCM, and the correlates of these constructs among 400 HIV clients with fertility intentions in Uganda. Measures included awareness, self-efficacy, and motivation regarding SCM, as well as demographics, health management, partner and provider characteristics. Just over half knew that MSI (53%) and TUI (51%) reduced transmission risk during conception, and 15% knew of sperm washing and pre-exposure prophylaxis. In separate regression models for SCM awareness, motivation, and …

Sexualization, Sex Discrimination, And Public School Dress Codes, Meredith Johnson Harbach

University of Richmond Law Review

This essay joins the conversation about sexualization, sex discrimination, and public school dress codes to situate current debates within in the broader cultural and legal landscapes in which they exist. My aim is not to answer definitively the questions I pose above. Rather, I ground the controversy in these broader contexts in order to better understand the stakes and to glean insights into how schools, students, and communities might better navigate dress code debates.

Myonuclear Transcription Is Responsive To Mechanical Load And Dna Content But Uncoupled From Cell Size During Hypertrophy, Tyler J. Kirby, Rooshil M. Patel, Timothy S. Mcclintock, Esther E. Dupont-Versteegden, Charlotte A. Peterson, John J. Mccarthy

Physiology Faculty Publications

Myofibers increase size and DNA content in response to a hypertrophic stimulus, thus providing a physiological model with which to study how these factors affect global transcription. Using 5-ethynyl uridine (EU) to metabolically label nascent RNA, we measured a sevenfold increase in myofiber transcription during early hypertrophy before a change in cell size and DNA content. The typical increase in myofiber DNA content observed at the later stage of hypertrophy was associated with a significant decrease in the percentage of EU-positive myonuclei; however, when DNA content was held constant by preventing myonuclear accretion via satellite cell depletion, both the number …

Identification Of An Association Of Tnfaip3 Polymorphisms With Matrix Metalloproteinase Expression In Fibroblasts In An Integrative Study Of Systemic Sclerosis-Associated Genetic And Environmental Factors*, Peng Wei, Yang Yang, Xinjian Guo, Nainan Hei, Syeling Lai, Shervin Assassi, Mengyuan Liu, Filemon Tan, Xiaodong Zhou

Faculty, Staff and Students Publications

OBJECTIVE: Systemic sclerosis (SSc) is a fibrotic disease attributed to both genetic susceptibility and environmental factors. This study was undertaken to investigate the associations between SSc-associated genetic variants and the expression of extracellular matrix (ECM) genes in human fibroblasts stimulated with silica particles in time-course and dose-response experiments.

METHODS: A total of 200 fibroblast strains were examined for ECM gene expression after stimulation with silica particles. The fibroblasts were genetically profiled using Immunochip assays and then subjected to whole-genome genotype imputation. Associations of genotypes and gene expression were first analyzed in a Caucasian cohort and then validated in a meta-analysis …

OBJECTIVE: It is critical that pediatric residents learn to effectively screen families for active and addressable social needs (ie, negative social determinants of health). We sought to determine 1) whether a brief intervention teaching residents about IHELP, a social needs screening tool, could improve resident screening, and 2) how accurately IHELP could detect needs in the inpatient setting.

METHODS: During an 18-month period, interns rotating on 1 of 2 otherwise identical inpatient general pediatrics teams were trained in IHELP. Interns on the other team served as the comparison group. Every admission history and physical examination (H&P) was reviewed for IHELP …

Genomic Characterization Of Patient-Derived Xenograft Models Established From Fine Needle Aspirate Biopsies Of A Primary Pancreatic Ductal Adenocarcinoma And From Patient-Matched Metastatic Sites, Robert J. Allaway, Dawn A. Fischer, Francine B. De Abreu, Timothy B. Gardner, Stuart R. Gordon, Richard J. Barth, Thomas A. Colacchio, Matthew Wood, Balint Z. Kacsoh, Stephanie J. Bouley

Dartmouth Scholarship

N-of-1 trials target actionable mutations, yet such approaches do not test genomically-informed therapies in patient tumor models prior to patient treatment. To address this, we developed patient-derived xenograft (PDX) models from fine needle aspiration (FNA) biopsies (FNA-PDX) obtained from primary pancreatic ductal adenocarcinoma (PDAC) at the time of diagnosis. Here, we characterize PDX models established from one primary and two metastatic sites of one patient. We identified an activating KRAS G12R mutation among other mutations in these models. In explant cells derived from these PDX tumor models with a KRAS G12R mutation, treatment with inhibitors of CDKs (including CDK9) reduced …

Modulating Foveal Representation Can Influence Visual Discrimination In The Periphery, Qing Yu, Won Mok Shim

Dartmouth Scholarship

A previous study by Williams et al. (2008) provided evidence for a novel form of feedback in the visual system, whereby peripheral information is contained in foveal retinotopic cortex. Beyond its possible implication for peripheral object recognition, few studies have examined the effect of a direct behavioral manipulation of the foveal feedback representation. To address this question, we measured participants' peripheral visual discrimination performance while modulating their foveal representation in a series of psychophysical experiments. On each trial, participants discriminated the identities of briefly presented novel, three-dimensional objects or the orientations of gratings in a peripheral location while fixating at …

Gender Representation In The Vision Sciences: A Longitudinal Study, Emily A. Cooper, Ana Radonjic

Dartmouth Scholarship

Understanding the current status and historical trends of gender representation within a research field is an important component of fostering a diverse and inclusive scientific community. Here, we report on the gender representation of a large sample of the vision science research community—the attendees of the Annual Meeting of the Vision Sciences Society (VSS). Our analysis shows that the majority of scientists at all career levels in our sample are male. This imbalance is most pronounced for the senior scientists, whereas predoctoral students are nearly balanced between the genders. Historically, the gender imbalance was larger than it is at present, …

HDL from healthy humans and lean mice inhibits palmitate-induced adipocyte inflammation; however, the effect of the inflammatory state on the functional properties of HDL on adipocytes is unknown. Here, we found that HDL from mice injected with AgNO₃ fails to inhibit palmitate-induced inflammation and reduces cholesterol efflux from 3T3-L1 adipocytes. Moreover, HDL isolated from obese mice with moderate inflammation and humans with systemic lupus erythematosus had similar effects. Since serum amyloid A (SAA) concentrations in HDL increase with inflammation, we investigated whether elevated SAA is a causal factor in HDL dysfunction. HDL from AgNO₃-injected mice lacking Saa1.1 …

What The Children Are Reading: A Content Analysis Of Minority Male Characters In Preschool Children's Libraries, Joan Katrina Mann-Boykin

Electronic Theses and Dissertations

Many early childhood classroom environments have a library area, which has picture books for the children to explore and enjoy, and some early childhood classrooms put tubs or baskets of a few picture books in every center in the classroom. In addition to inspiring a love of reading and providing hours of enjoyment, children's literature serves emotional, social, intellectual, linguistic and literary purposes (Temple, Martinez, Yokota & Naylor, 2002). A primary goal in early childhood programs is to welcome and embrace the diversity of children and families in today's multicultural society (Brinson, 2012) and children's books provide a wonderful way …
