Telehealth: Into The Mainstream?, Lisa Sprague

National Health Policy Forum

Teleheath, and its subset telemedicine, extend across a range of technologies allowing patients to seek diagnosis, treatment, and other services from clinicians by electronic means. Telephone, videoconferencing, iPads, and apps are all employed. In its most established form, hospitals and medical centers use telehealth to reach patients in underserved rural areas. Proponents of telehealth suggest it can relieve medical workforce shortages; save patients time, money, and travel; reduce unnecessary hospital visits; improve the management of chronic conditions; and improve continuing medical education. But telehealth also faces ongoing challenges. States require physicians to be licensed in each state where they treat …

Chagas Disease In The 21st Century: A Public Health Success Or An Emerging Threat?, Kevin M. Bonney

Publications and Research

Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major public health burden in Latin America and a potentially serious emerging threat to a number of countries throughout the world. Although public health programs have significantly reduced the prevalence of Chagas disease in Latin America in recent decades, the number of infections in the United States and non-endemic countries in Europe and the Western Pacific Region continues to rise. Moreover, there is still no vaccine or highly effective cure available for the approximately 10 million people currently infected with T. cruzi, a third of which will develop potentially …

An Autoreactive Antibody From An Sle/Hiv-1 Individual Broadly Neutralizes Hiv-1, Mattia Bonsignori, Kevin Wiehe, Sebastian K. Grimm, Rebecca Lynch, Guang Yang, Daniel M. Kozink, Florence Perrin, Abby J. Cooper, Kwan-Ki Hwang, Xi Chen, Mengfei Liu, Krisha Mckee, Robert J. Parks, Joshua Eudailey, Minyue Wang, Megan Clowse, Lisa G.

Dartmouth Scholarship

Broadly HIV-1–neutralizing antibodies (BnAbs) display one or more unusual traits, including a long heavy chain complementarity-determining region 3 (HCDR3), polyreactivity, and high levels of somatic mutations. These shared characteristics suggest that BnAb development might be limited by immune tolerance controls. It has been postulated that HIV-1–infected individuals with autoimmune disease and defective immune tolerance mechanisms may produce BnAbs more readily than those without autoimmune diseases. In this study, we identified an HIV-1–infected individual with SLE who exhibited controlled viral load (<5,000 copies/ml) in the absence of controlling HLA phenotypes and developed plasma HIV-1 neutralization breadth. We collected memory B cells from this individual and isolated a BnAb, CH98, that targets the CD4 binding site (CD4bs) of HIV-1 envelope glycoprotein 120 (gp120). CH98 bound to human antigens including dsDNA, which is specifically associated with SLE. Anti-dsDNA reactivity was also present in the patient’s plasma. CH98 had a mutation frequency of 25% and 15% nt somatic mutations in the heavy and light chain variable domains, respectively, a long HCDR3, and a deletion in the light chain CDR1. The occurrence of anti-dsDNA reactivity by a HIV-1 CD4bs BnAb in an individual with SLE raises the possibility that some BnAbs and SLE-associated autoantibodies arise from similar pools of B cells.

Selectivity And Potency Of Microcystin Congeners Against Oatp1b1 And Oatp1b3 Expressing Cancer Cells, Timo H.J. Niedermeyer, Abigail Daily, Monika Swiatecka-Hagenbruch, Jeffrey A. Moscow

Pediatrics Faculty Publications

Microcystins are potent phosphatase inhibitors and cellular toxins. They require active transport by OATP1B1 and OATP1B3 transporters for uptake into human cells, and the high expression of these transporters in the liver accounts for their selective hepatic toxicity. Several human tumors have been shown to have high levels of expression of OATP1B3 but not OATP1B1, the main transporter in liver cells. We hypothesized that microcystin variants could be isolated that are transported preferentially by OATP1B3 relative to OATP1B1 to advance as anticancer agents with clinically tolerable hepatic toxicity. Microcystin variants have been isolated and tested for cytotoxicity in cancer cells …

An Optogenetic Gene Expression System With Rapid Activation And Deactivation Kinetics, Laura B. Motta-Mena, Anna Reade, Michael J. Mallory, Spencer Glantz, Orion D. Weiner, Kristen W. Lynch, Kevin H. Gardner

Advanced Science Research Center

Optogenetic gene expression systems can control transcription with spatial and temporal detail unequaled with traditional inducible promoter systems. However, current eukaryotic light-gated transcription systems are limited by toxicity, dynamic range, or slow activation/deactivation. Here we present an optogenetic gene expression system that addresses these shortcomings and demonstrate its broad utility. Our approach utilizes an engineered version of EL222, a bacterial Light-Oxygen-Voltage (LOV) protein that binds DNA when illuminated with blue light. The system has a large (>100-fold) dynamic range of protein expression, rapid activation (< 10 s) and deactivation kinetics (< 50 s), and a highly linear response to light. With this system, we achieve light-gated transcription in several mammalian cell lines and intact zebrafish embryos with minimal basal gene activation and toxicity. Our approach provides a powerful new tool for optogenetic control of gene expression in space and time.

Introduction: Currently there are several advanced guiding techniques for pathoanatomical diagnosis of incidental solitary pulmonary nodules (iSPN): Electromagnetic navigation (EMN) with or without endobronchial ultrasound (EBUS) with miniprobe, transthoracic ultrasound (TTUS) for needle approach to the pleural wall and adjacent lung and computed tomography (CT)-guidance for (seldom if ever used) endobronchial or (common) transthoracical approach. In several situations one technique is not enough for efficient diagnosis, therefore we investigated a new diagnostic technique of endobronchial guided biopsies by a Cone Beam Computertomography (CBCT) called DynaCT (SIEMENS AG Forchheim, Germany). Method and Material: In our study 33 incidental solitary pulmonary nodules …

La Temporalidad De Lo Breve, Vanina Noejovich

Modern Languages and Literatures Annual Graduate Conference

El artículo se acerca a la caracterización de lo breve a partir de dos temporalidades diversas: lo breve definido desde su duración como elemento de una cadena de acontecimientos y lo breve como irrupción en dicha cadena de contecimientos, que permite pensar otra temporalidad, la de las repercusiones de lo breve. Para definir la temporalidad de las repercusiones de lo breve, el artículo se apoya en la teoría psicoanalítica de Jacques Lacan, particularmente en la definición de la interpretación psi-coanalítica como acto analítco. Para contraponer las repercusiones de lo breve con el tiempo de duración el artículo refle-xiona acerca de …

Clay Modeling Of The Musculoskeletal System: Does Active Learning Increase Retention And Comprehension, Kelly Massey

Interdisciplinary STEM Teaching & Learning Conference (2012-2019) (Archived)

The focus of a Structural Kinesiology course is a detailed study into the musculoskeletal system and joint action. The course contains a lot of memorization: skeletal muscle origin, insertions, innervations and muscle/joint actions but there is also an applied component for the content. Group study has been incorporated into the course to increase knowledge retention and comprehension however group interaction has been seen to be minimal. Two studies have looked at group construction of skeletal muscle models using clay during class time in assisting with the active learning of muscle origin, insertion and actions (Cruz-Espaillat et al., 2010 & Waters …

P-12 A Study On The Relationship Between Gre Scores Of Pre-Physical Therapy Students And National Physical Therapy Examination Scores: A Retrospective Study Of One Midwestern Physical Therapy Program, Givan Hinds

Honors Scholars & Undergraduate Research Poster Symposium Programs

Background: This study explored relationships between Graduate Record Examination (GRE) and National Physical Therapy Examination (NPTE) scores. Methodology: This is a retrospective correlational design utilizing a purposive sample (n = 102) of Doctor of Physical Therapy (DPT) students from three consecutive cohorts. Correlations were examined between GRE Verbal (GREV), GRE Quantitative (GREQ), and GRE Total (GRET) scores with the NPTE pass rate utilizing a Spearman rho correlation coefficient.

Prevention and Community Health Faculty Publications

Introduction
Health education provided to patients can reduce mortality and morbidity of chronic disease. Although some studies describe the provision of health education by physicians, few studies have examined how physicians, physician assistants, and nurse practitioners differ in the provision of health education. The objective of our study was to evaluate the rate of health education provision by physicians, physician assistants, and nurse practitioners/certified midwives.

Methods
We analyzed 5 years of data (2005–2009) from the outpatient department subset of the National Hospital Ambulatory Medical Care Survey. We abstracted data on 136,432 adult patient visits for the following chronic conditions: asthma, …

Syphilis: A Forgotten Sexually Transmitted Disease?, Amy Burnett, Hatim A. Omar

Pediatrics Faculty Publications

Syphilis has declined significantly over the last 30 years. Due to that success, many physicians no longer have the skills to recognize its symptoms. We present a case of syphilis as a demonstration of this fact and hope that health professionals in the field of adolescent medicine will think about this diagnosis in their clinical work.

Pediatrics Faculty Publications

We used a cost-effective, non-invasive method to obtain high-quality DNA from buccal epithelial-cells (BEC) of premature infants for genomic analysis. DNAs from BEC were obtained from premature infants with gestational age ≤ 36 weeks. Short terminal repeats (STRs) were performed simultaneously on DNA obtained from the buccal swabs and blood from the same patient. The STR profiles demonstrated that the samples originated from the same individual and exclude any contamination by external DNAs. Whole exome sequencing was performed on DNAs obtained from BEC on premature infants with and without necrotizing enterocolitis, and successfully provided a total number of reads and …

A Novel Three Serum Phospholipid Panel Differentiates Normal Individuals From Those With Prostate Cancer, Nima Patel, Robert L. Vogel, Kumar Chandra-Kuntal, Wayne Glasgow, Uddhav Kelavkar

Biostatistics: Faculty Publications

Background: The results of prostate specific antigen (PSA) and digital rectal examination (DRE) screenings lead to both under and over treatment of prostate cancer (PCa). As such, there is an urgent need for the identification and evaluation of new markers for early diagnosis and disease prognosis. Studies have shown a link between PCa, lipids and lipid metabolism. Therefore, the aim of this study was to examine the concentrations and distribution of serum lipids in patients with PCa as compared with serum from controls.

Method: Using Electrospray ionization mass spectrometry (ESI-MS/MS) lipid profiling, we analyzed serum phospholipids from age-matched subjects who …

Prevention and Community Health Faculty Publications

Background

There is a huge interest by faith-based organizations (FBOs) in sub-Saharan Africa and elsewhere in HIV prevention interventions that build on the religious aspects of being. Successful partnerships between the public health services and FBOs will require a better understanding of the conceptual framing of HIV prevention by FBOS to access for prevention intervention, those concepts the churches of various denominations and their members would support or endorse. This study investigated the conceptual framing of HIV prevention among church youths in Botswana; - a country with one of the highest HIV prevalence in the world.

Fused In Sarcoma Is A Novel Regulator Of Manganese Superoxide Dismutase Gene Transcription, Sanjit Kumar Dhar, Jiayu Zhang, Jozsef Gal, Yong Xu, Lu Miao, Bert C. Lynn, Haining Zhu, Edward J. Kasarskis, Daret K. St. Clair

Toxicology and Cancer Biology Faculty Publications

AIMS: FUsed in sarcoma (FUS) is a multifunctional DNA/RNA-binding protein that possesses diverse roles, such as RNA splicing, RNA transport, DNA repair, translation, and transcription. The network of enzymes and processes regulated by FUS is far from being fully described. In this study, we have focused on the mechanisms of FUS-regulated manganese superoxide dismutase (MnSOD) gene transcription.

RESULTS: Here we demonstrate that FUS is a component of the transcription complex that regulates the expression of MnSOD. Overexpression of FUS increased MnSOD expression in a dose-dependent manner and knockdown of FUS by siRNA led to the inhibition of MnSOD gene transcription. …

Redox-Modulated Phenomena And Radiation Therapy: The Central Role Of Superoxide Dismutases, Aaron K. Holley, Lu Miao, Yanming Zhao, Daret K. St. Clair, William H. St. Clair

Toxicology and Cancer Biology Faculty Publications

SIGNIFICANCE: Ionizing radiation is a vital component in the oncologist's arsenal for the treatment of cancer. Approximately 50% of all cancer patients will receive some form of radiation therapy as part of their treatment regimen. DNA is considered the major cellular target of ionizing radiation and can be damaged directly by radiation or indirectly through reactive oxygen species (ROS) formed from the radiolysis of water, enzyme-mediated ROS production, and ROS resulting from altered aerobic metabolism.

RECENT ADVANCES: ROS are produced as a byproduct of oxygen metabolism, and superoxide dismutases (SODs) are the chief scavengers. ROS contribute to the radioresponsiveness of …

Influence Of The X-Chromosome On Neuroanatomy: Evidence From Turner And Klinefelter Syndromes., David S Hong, Fumiko Hoeft, Matthew J Marzelli, Jean-Francois Lepage, David Roeltgen, Judith L. Ross, Allan L Reiss

Department of Psychiatry and Human Behavior Faculty Papers

Studies of sex effects on neurodevelopment have traditionally focused on animal models investigating hormonal influences on brain anatomy. However, more recent evidence suggests that sex chromosomes may also have direct upstream effects that act independently of hormones. Sex chromosome aneuploidies provide ideal models to examine this framework in humans, including Turner syndrome (TS), where females are missing one X-chromosome (45X), and Klinefelter syndrome (KS), where males have an additional X-chromosome (47XXY). As these disorders essentially represent copy number variants of the sex chromosomes, investigation of brain structure across these disorders allows us to determine whether sex chromosome gene dosage effects …
