Human Papillomavirus: The Influence Of Prevention And Vaccination, Lacey N. Russell

Kentucky Journal of Undergraduate Scholarship

Human Papillomavirus infections (HPV) are the most common sexually transmitted diseases in the United States. Of cancers in parts of the body where HPV is often discovered about 80% originated from an HPV infection. Despite this knowledge and the effectiveness of the HPV vaccine, vaccination by both genders in Kentucky and on a national scale remains highly underutilized. As a result, preventable incidence and mortality rates from HPV-related illness are elevated. Health care delivery factors such as increased vaccination and preventative care, insurance coverage, and accessible rural health care are necessary for HPV prevention and promotion of holistic health. The …

Herpes Zoster Patient Education: A Coloring Book Approach, Sophia Charuhas

Senior Honors Theses

Shingles, the disease caused by the herpes zoster virus, is a widespread and widely misunderstood illness in the United States. It is preventable, but many at-risk patients do not know what measures they may take to prevent it. Clear communication from physician to patient is crucial for patient understanding of diseases. Many patient education materials on herpes zoster currently available are often unused. It is therefore beneficial to public health to disseminate new mediums of medical communication, and one way of accomplishing this is through adult coloring books. The pathophysiology of herpes zoster virus is here explored and the idea …

An Assessment Of Cultural Perceptions And Recognition Of Ebola Virus Disease, And Its Correlation With Traditional Burial Practice In Rural Guinea, Chulwoo Park, Amira Roess, Sally Lahm, Mamadou Kally Bah, Mohamed Campel Camara, John Sandberg

GW Research Days 2016 - 2020

Background:

In the midst of the unprecedented Ebola outbreak in West Africa during 2014-2016, the humanitarian response to control the disease was hampered in part because there was a limited understanding of local traditional rituals or indigenous medicine (ethnomedicine) on the part of the responders. The Ebola outbreak claimed 11,310 lives, more than all other outbreaks combined. West African burial funeral ceremonies and surrounding rituals may have hindered interventions that included the forceful removal of the sick or dead from the community.

Objective:

Our objective was to understand transmission associated with traditional burial practices in rural Guinea. Through the lens …

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 …

Mbabazi, H. Wesley Perkins, Alexander C. Tsai, Sv Subramanian, Nicholas A. Christakis, David Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV testing is an essential part of treatment and prevention. Using population-based data from 1664 adults across eight villages in rural Uganda, we assessed individuals’ perception of the norm for HIV testing uptake in their village and compared it to the actual uptake norm. In addition, we examined how perception of the norm was associated with personal testing while adjusting for other factors. Although the majority of people had been tested for HIV across all villages, slightly more than half of men and women erroneously thought that the majority in their village had never been tested. They underestimated the prevalence …

Improving Hpv Vaccination Series Initiation Rates And Compliance Among Indigent Women In South Texas, Ages 19-26, Through Provider Recommendation And Additional Clinic Funding: A Quality Improvement Project, Lacey Cudd

Doctor of Nursing Practice

The purpose of this quality improvement project was to increase human papillomavirus vaccination series initiation rates among indigent women, ages 19-26, at a clinic in South Texas. The human papillomavirus is a sexually transmitted infection that has been associated with multiple types of cancers. Each year, approximately 6.2 million cases of the human papillomavirus infection are diagnosed; as many as 75% of all new infections occur among females 18-26 years of age. The human papillomavirus vaccination has a high efficacy in regards to cancer prevention, preventing as many as 76% of cancers with only one dose. The project included educating …

Six-Year Experience Of Influenza Vaccination As A Condition Of Employment For A Large Regional Health Care System, John R. Brill, Mark Hermanoff, Angela Tonozzi, Mary Jo Capodice, Jennifer Farrar, Zarina Dawoodbhai

Journal of Patient-Centered Research and Reviews

Background: Influenza remains a significant contributor to morbidity and mortality in the United States. Health care workers (HCW) can be both victims and vectors of influenza. Influenza vaccination of HCW is protective for both caregivers and patients, but voluntary programs generally fail to achieve rates recommended by the Centers for Disease Control and Prevention. Despite a complex, multifaceted influenza program initiated in 1996 that included significant education and promotion as well as free on-site vaccination, annual Aurora Health Care caregiver immunization rates remained in the mid-70s until adoption of a “condition of employment” strategy in 2011.

Purpose: Discuss the annual …

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …

Anti-Herv-K (Hml-2) Capsid Antibody Responses In Hiv Elite Controllers., Miguel De Mulder, Devi Sengupta, Steven G Deeks, Jeffrey N Martin, Christopher D Pilcher, Frederick M Hecht, Jonah B Sacha, Douglas F Nixon, Henri-Alexandre Michaud

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Human endogenous retroviruses (HERVs) comprise approximately 8% of the human genome and while the majority are transcriptionally silent, the most recently integrated HERV, HERV-K (HML-2), remains active. During HIV infection, HERV-K (HML-2) specific mRNA transcripts and viral proteins can be detected. In this study, we aimed to understand the antibody response against HERV-K (HML-2) Gag in the context of HIV-1 infection.

Results

We developed an ELISA assay using either recombinant protein or 164 redundant “15mer” HERV-K (HML-2) Gag peptides to test sera for antibody reactivity. We identified a total of eight potential HERV-K (HML-2) Gag immunogenic domains: two on …

Vorinostat Renders The Replication-Competent Latent Reservoir Of Human Immunodeficiency Virus (Hiv) Vulnerable To Clearance By Cd8 T Cells., Julia A Sung, Katherine Sholtis, Jennifer Kirchherr, Joann D Kuruc, Cynthia L Gay, Jeffrey L Nordstrom, Catherine M Bollard, Nancie M Archin, David M Margolis

Pediatrics Faculty Publications

Latently human immunodeficiency virus (HIV)-infected cells are transcriptionally quiescent and invisible to clearance by the immune system. To demonstrate that the latency reversing agent vorinostat (VOR) induces a window of vulnerability in the latent HIV reservoir, defined as the triggering of viral antigen production sufficient in quantity and duration to allow for recognition and clearance of persisting infection, we developed a latency clearance assay (LCA). The LCA is a quantitative viral outgrowth assay (QVOA) that includes the addition of immune effectors capable of clearing cells expressing viral antigen. Here we show a reduction in the recovery of replication-competent virus from …

Hepatitis C Virus And Nonliver Solid Cancers: Is There An Association Between Hcv And Cancers Of The Pancreas, Thyroid, Kidney, Oral Cavity, Breast, Lung, And Gastrointestinal Tract?, S Qadwai, T Rehman, Jonathan Barsa, Z Solangi, Edward Lebovics

NYMC Faculty Publications

Hepatitis C virus (HCV) is known for its oncogenic potential and has been found to be associated with hepatocellular carcinoma (HCC) and non-Hodgkin lymphoma. It has also been postulated that HCV may play a role in the development of other extrahepatic solid tumors of other organs of the body since it has been isolated from the vessel wall, kidney, and oral mucosa. In this article, we have reviewed epidemiological studies that have been done to look into the relationship of HCV with nonliver solid cancers of the pancreas, thyroid, renal, oral cavity, breast, and lung and nonpancreatic gastrointestinal cancers. Based …

A Comparative Analysis Of The West African Hemorrhagic Fevers Caused By The Lassa And Ebola Viruses, Emiene E. Amali-Adekwu

Selected Honors Theses

Lassa fever (LF) and Ebola Hemorrhagic Fever (EHF) are viral diseases endemic to West Africa.The etiological agent of Lassa fever is an enveloped virus from the Arenaviridae family and was first discovered in 1969 when two missionary nurses died of a mysterious illness in the town of Lassa in Borno state, Nigeria.1 This virus is animal-borne (zoonotic) and is carried by the animal vector Mastomys natalensis (multimammate rat). The Ebola virus is also zoonotic originating from fruit bats belonging to the Pteropodidae family.2 The first reported case of Ebola Virus Disease (EVD) was a principal who was believed to have …

No indigenous cases of poliomyelitis have occurred in the US since 1979; however the risk of importation persists until global eradication is achieved. The seropositivity rate for different age cohorts with exposures to different poliovirus vaccine types and wild virus in the US are not presently known. A convenience sample was conducted in the Kansas City metropolitan area during 2012-2103 with approximately 100 participants enrolled for each of 5 age cohorts categorized based on vaccine policy changes over time in the US. Immunization records for poliovirus vaccination were required for participants90.7%, 94.4%, and 83.3%, for types 1, 2, and 3, …

Zika Virus From A Neonatologist’S Perspective, A Zylak, Sergio Golombek

NYMC Faculty Publications

Zika virus has been known for more than half a century. Its clinical significance was just recently discovered, after the epidemic of Zika virus emerged in South and Central America. A task force established in 2015 by the Brazil Ministry of Health investigated the possible association between congenital Zika infection and microcephaly in fetuses and newborns. Since then more and more evidence emerged, supporting this hypothesis. The objective of this article is to review and summarize the currently available literature regarding Zika virus from a neonatologist’s standpoint and provide some guidance to medical providers who may have to care for …

One of the largest single sources of epilepsy in the world is produced as a neurological sequela in survivors of cerebral malaria. Nevertheless, the pathophysiological mechanisms of such epileptogenesis remain unknown and no adjunctive therapy during cerebral malaria has been shown to reduce the rate of subsequent epilepsy. There is no existing animal model of postmalarial epilepsy. In this technical report we demonstrate the first such animal models. These models were created from multiple mouse and parasite strain combinations, so that the epilepsy observed retained universality with respect to genetic background. We also discovered spontaneous sudden unexpected death in epilepsy …

Parvovirus B19 Ns1 Protein Induces Cell Cycle Arrest At G2-Phase By Activating The Atr-Cdc25c-Cdk1 Pathway., Peng Xu, Zhe Zhou, Min Xiong, Wei Zou, Xuefeng Deng, Safder S. Ganaie, Steve Kleiboeker, Jianxin Peng, Kaiyu Liu, Shengqi Wang, Shui Qing Ye, Jianming Qiu

Manuscripts, Articles, Book Chapters and Other Papers

Human parvovirus B19 (B19V) infection of primary human erythroid progenitor cells (EPCs) arrests infected cells at both late S-phase and G2-phase, which contain 4N DNA. B19V infection induces a DNA damage response (DDR) that facilitates viral DNA replication but is dispensable for cell cycle arrest at G2-phase; however, a putative C-terminal transactivation domain (TAD2) within NS1 is responsible for G2-phase arrest. To fully understand the mechanism underlying B19V NS1-induced G2-phase arrest, we established two doxycycline-inducible B19V-permissive UT7/Epo-S1 cell lines that express NS1 or NS1mTAD2, and examined the function of the TAD2 domain during G2-phase arrest. The results confirm that the …

Yeast Help Identify Cytopathic Factors Of Zika Virus, Michael I. Bukrinsky

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Accumulating evidence implicates Zika virus (ZIKV) in pathogenesis of microcephaly in newborns and Guillain-Barré syndrome in adults. However, it remains unclear which viral proteins are responsible for these effects and what are the underlying mechanisms of their pathogenic activity. A recent paper by Drs. Zhao and Gallo, and their colleagues at University of Maryland in Baltimore used fission yeast for genome-wide analysis of ZIKV proteins. They demonstrated cytopathogenic activity for seven ZIKV proteins, anaC, C, prM, M, E, NS2B and NS4A. This activity was shown to be dependent on oxidative stress, and for NS4A they demonstrated involvement of the TOR …

Mait Cells Are Reduced In Frequency And Functionally Impaired In Human T Lymphotropic Virus Type 1 Infection: Potential Clinical Implications., Dominic Paquin-Proulx, Benjamin C Greenspun, Emanuela A S Costa, Aluisio C Segurado, Esper G Kallas, Douglas F Nixon, Fabio E Leal

Microbiology, Immunology, and Tropical Medicine Faculty Publications

HTLV-1 infection is associated with several inflammatory disorders, including the neurodegenerative condition HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). It is unclear why a minority of infected subjects develop HAM/TSP. The cellular immune response has been implicated in the development of inflammatory alterations in these patients; however the pathogenic mechanisms for disease progression remain unclear. Furthermore, HTLV-1-infected individuals have an increase incidence of Mycobacterium tuberculosis (Mtb) infection, suggesting that immunological defect are associated with HTLV-1 infection. Evidence suggests an important role for Mucosal-associated invariant T (MAIT) cells in the early control of Mtb infection. Chronic viral infections like HIV and HCV have …
