Epidemiology Of Hiv Among American Indians And Alaska Natives – United States, 2008-2011, Frances J. Walker, Jane M. Kelly, Mona Doshani, Neeraja Saduvala, Joseph Prejean

Journal of Health Disparities Research and Practice

American Indians/Alaska Natives (AI/AN) diagnosed with HIV infection have poorer survivorship and a higher percentage of Stage 3 (AIDS] diagnoses within one year of HIV diagnosis, compared to most race/ethnicity groups. National HIV surveillance data for 2008-2011 were used to determine diagnosis rates of HIV infection, persons living with HIV, and persons with a late diagnosis (Stage 3 within three months of HIV diagnosis) by selected characteristics for AI/AN and a combined other race/ethnicity group. The highest percentages of 862 AI/AN diagnosed with HIV infection were among males (75.7%), AI/AN aged 25-34 years (32.9%), persons living in large metropolitan areas …

Community Based Participatory Research: The Application And Lessons Learned From A Study With Lgb College Students, Caitlin M. Stover

Journal of Health Disparities Research and Practice

Lesbian, gay, and bisexual (LGB) individuals are members of a vulnerable group where health disparities have been identified. To gain a better understanding of the LGB college student healthcare experience and its contribution to the healthcare disparities found in LGB population, a community based participatory research (CBPR) approach was used to fill the gap. This paper will outline the CBPR process with an emphasis on how the principle investigator applied the tenets of CBPR when working with a local LGB college community. Several lessons learned from the research process are also shared in this paper.

Understanding How Components Of Black Racial Identity And Racial Realities May Impact Healthcare Utilization: A Randomized Study, Alexander M. Chaitoff, Thomas Wickizer, Ismail White

Journal of Health Disparities Research and Practice

Purpose: Studies have suggested that even when minority groups have potential access to healthcare, they may have inadequate utilization (realized access). This study explores the application of a theory from the social psychology and political science literatures concerning how racial centrality and racial realities, specifically amongst Blacks, may influence patients’ healthcare utilization preferences.

Methods: We created a survey with two (pseudo) randomized, controlled experimental treatments designed to assess whether racialized hospital and physician characteristics elicited a preference from Black or White respondents, as well as questions aimed at understanding participants’ different beliefs and levels of knowledge about past and current …

Phylogenetic Investigation Of Enteric Bovine Coronavirus In Ireland Reveals Partitioning Between European And Global Strains, Lynda Gunn, P. J. Collins, M. J. O'Connell, Helen O'Shea

Department of Biological Sciences Publications

Background

Bovine coronavirus is a primary cause of neonatal calf diarrhea worldwide, and is also associated with acute diarrhea in adult cattle during the winter season. There are no reports on molecular characterization of bovine coronavirus in Ireland, and little data exists apart from serological studies.

Findings

In this study, 11 neonatal (mean age 9 days) calf BCoV strains from the south of Ireland were collected over a one year period and characterized using molecular methods. The spike gene which encodes a protein involved in viral entry, infectivity and immune response shows the most variability amongst the isolates and was …

Time Preferences Predict Mortality Among Hiv-Infected Adults Receiving Antiretroviral Therapy In Kenya, Harsha Thirumurthy, Kami Hayashi, Sebastian Linnemayr, Rachel C. Vreeman, Irwin P. Levin, David Bangsberg, Noel T. Brewer

OHSU-PSU School of Public Health Faculty Publications and Presentations

Identifying characteristics of HIV-infected adults likely to have poor treatment outcomes can be useful for targeting interventions efficiently. Research in economics and psychology suggests that individuals’ intertemporal time preferences, which indicate the extent to which they trade-off immediate vs. future cost and benefits, can influence various health behaviors. While there is empirical support for the association between time preferences and various non-HIV health behaviors and outcomes, the extent to which time preferences predict outcomes of those receiving antiretroviral therapy (ART) has not been examined previously.

HIV-infected adults initiating ART were enrolled at a health facility in Kenya. Participants’ time preferences …

Hiv-1-Tat Protein Inhibits Sc35-Mediated Tau Exon 10 Inclusion Through Up-Regulation Of Dyrk1a Kinase, Ferdous Kadri, Marco Pacifici, Anna Wilk, Amanda Parker-Struckhoff, Luis Del Valle, Kurt F. Hauser, Pamela E. Knapp, Christopher Parsons, Duane Jeansonne, Adam Lassak, Francesca Peruzzi

School of Medicine Faculty Publications

The HIV-1 transactivator protein Tat is implicated in the neuronal damage that contributes to neurocognitive impairment affecting people living with HIV/AIDS. Aberrant splicing of TAU exon 10 results in tauopathies characterized by alterations in the proportion of TAU isoforms containing three (3R) or four (4R) microtubule-binding repeats. The splicing factor SC35/SRSF2 binds to nuclear RNA and facilitates the incorporation of exon 10 in the TAU molecule. Here, we utilized clinical samples, an animal model, and neuronal cell cultures and found that Tat promotes TAU 3R up-regulation through increased levels of phosphorylated SC35, which is retained in nuclear speckles. This mechanism …

Viral Infection Causes A Shift In The Self Peptide Repertoire Presented By Human Mhc Class I Molecules, Charles T. Spencer, Jelena S. Bezbradica, Mireya G. Ramos, Chenoa D. Arico, Stephanie B. Conant, Pavlo Gilchuk, Jennifer J. Gray, Mu Zheng, Xinnan Niu, William Hildebrand, Andrew J. Link, Sebastian Joyce

Chemistry Faculty Research

Purpose

MHC class I presentation of peptides allows T cells to survey the cytoplasmic protein milieu of host cells. During infection, presentation of self peptides is, in part, replaced by presentation of microbial peptides. However, little is known about the self peptides presented during infection, despite the fact that microbial infections alter host cell gene expression patterns and protein metabolism.

Experimental design

The self peptide repertoire presented by HLA-A*01;01, HLA-A*02;01, HLA-B*07;02, HLA-B*35;01, and HLA-B*45;01 (where HLA is human leukocyte antigen) was determined by tandem MS before and after vaccinia virus infection.

Results

We observed a profound alteration in the self …

Whole-Genome Sequencing Of Kshv From Zambian Kaposi’S Sarcoma Biopsies Reveals Unique Viral Diversity, Landon N. Olp, Adrien Jeanniard, Clemence Marimo, John T. West, Charles Wood

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent for Kaposi’s sarcoma (KS). Both KSHV and KS are endemic in sub-Saharan Africa where approximately 84% of global KS cases occur. Nevertheless, whole-genome sequencing of KSHV has only been completed using isolates from Western countries—where KS is not endemic. The lack of whole-genome KSHV sequence data from the most clinically important geographical region, sub-Saharan Africa, represents an important gap as it remains unclear whether genomic diversity has a role on KSHV pathogenesis. We hypothesized that distinct KSHV genotypes might be present in sub-Saharan Africa compared to Western countries. Using a KSHV-targeted enrichment …

Ccr5 And The Blood Brain Barrier During Hiv-1 Infection And Cell-Cell Communications, Shawna M. Woollard

Theses & Dissertations

Human Immunodeficiency Virus (HIV-1) infection often results in blood-brain barrier (BBB) dysfunction and central nervous system (CNS) impairment. Since most viral strains that cross the BBB and enter the CNS are macrophage-tropic and use the C-C chemokine receptor type-5 (CCR5) to enter and infect target cells, we hypothesized that CCR5 plays a major role in monocytes-endothelial interactions and HIV-induced BBB dysfunction. Because the cytoskeleton is responsible for cellular morphology and motility, we further hypothesized that HIV-induced monocyte-endothelial interactions and transendothelial migration involve cytoskeletal changes and that CCR5 blockers would also affect these changes. To this end we used two small …

Investigation Of Stilbenoids As Potential Therapeutic Agents For Rotavirus Gastroenteritis, Judith M. Ball, Fabricio Medina-Bolivar, Katelyn D. Defrates, Emily Hambleton, Megan E. Hurlburt, Lingling Fang, Tianhong Yang, Luis Nopo-Olazabal, Richard L. Atwill, Pooj Ghai, Rebecca D. Parr

Rotavirus (RV) infections cause severe diarrhea in infants and young children worldwide. Vaccines are available but cost prohibitive for many countries and only reduce severe symptoms. Vaccinated infants continue to shed infectious particles, and studies show decreased efficacy of the RV vaccines in tropical and subtropical countries where they are needed most. Continuing surveillance for new RV strains, assessment of vaccine efficacy, and development of cost effective antiviral drugs remain an important aspect of RV studies. This study was to determine the efficacy of antioxidant and anti-inflammatory stilbenoids to inhibit RV replication. Peanut (A. hypogaea) hairy root cultures were induced …

Addressing Therapeutic Options For Ebola Virus Infection In Current And Future Outbreaks, Azizul Haque, Didier Hober, Joel Blondiaux

Dartmouth Scholarship

Ebola virus can cause severe hemorrhagic disease with high fatality rates. Currently, no specific therapeutic agent or vaccine has been approved for treatment and prevention of Ebola virus infection of humans. Although the number of Ebola cases has fallen in the last few weeks, multiple outbreaks of Ebola virus infection and the likelihood of future exposure highlight the need for development and rapid evaluation of pre- and postexposure treatments. Here, we briefly review the existing and future options for anti-Ebola therapy, based on the data coming from rare clinical reports, studies on animals, and results from in vitro models. We …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Sutherlandia frutescens (L.) R. Br. is widely used as an over the counter complementary medicine and in traditional medications by HIV seropositive adults living in South Africa; however the plant's safety has not been objectively studied. An adaptive two-stage randomized double-blind placebo controlled study was used to evaluate the safety of consuming dried S. frutescens by HIV seropositive adults with CD4 T-lymphocyte count of >350 cells/μL.

METHODS: In Stage 1 56 participants were randomized to S. frutescens 400, 800 or 1,200 mg twice daily or matching placebo for 24 weeks. In Stage 2 77 additional participants were randomized to …

Understanding The Irony: Canadian Gay Men Living With Hiv/Aids, Their Catholic Devotion, And Greater Well-Being, Renato M. Liboro, Richard T.G. Walsh

Psychology Faculty Research

Nine Canadian Catholic HIV-positive gay men were interviewed to obtain a better understanding of why and how they were able to persevere in their faith despite their religion’s teachings against homosexuality and contributions to the stigmatization of HIV/AIDS. By examining the lived experiences and personal perspectives of the participants, the study aimed to explore and elucidate the significant role of Catholicism and the Catholic Church both as a continued source of marginalization and oppression, as well as strength and support, for Canadian gay men living with HIV/AIDS today.

Improving Early Infant Hiv Diagnosis In Kenya: Study Protocol Of A Cluster-Randomized Efficacy Trial Of The Hitsystem., Sarah Finocchario-Kessler, Kathy Goggin, Samoel Khamadi, Brad Gautney, Jacinda K. Dariotis, Charles Bawcom, An-Lin Cheng, Niaman Nazir, Catherine Martin, Andrea Ruff, Michael Sweat, Vincent Okoth

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Early infant diagnosis among human immunodeficiency virus (HIV)-exposed infants is a critical component of prevention of mother-to-child transmission programs. Barriers to early infant diagnosis include poor uptake, low retention at designated re-testing intervals, delayed test results, passive systems of communication, and poor linkage to treatment. This study will evaluate the HIV Infant Tracking System (HITSystem), an eHealth intervention that streamlines communication and accountability between the key early infant diagnosis stakeholders: HIV+ mothers and their HIV-exposed infants, healthcare providers, and central laboratory personnel. It is hypothesized that the HITSystem will significantly improve early infant diagnosis retention at 9 and 18 …

Convalescent Serum Therapy As Rapid Advance Treatment For Ebola In West Africa, J Bankole Thompson Md, Phd, Patricia F. Mejabi Msc., Olugbenga O. Mejabi Phd, S Ahmed Tejan-Sie Md

International Journal of African Development

The 2014 public health crisis in Guinea, Liberia, and Sierra Leone has brought Ebola Viral Disease (EVD) to everyone’s attention. Discovered in 1976, this deadly disease infrequently struck in remote areas of Africa. This article will critically review the literature and describe the pathobiology, transmission, signs and symptoms, diagnosis, treatment, and prevention of EVDwhich, was predicted by the Centers for Disease Control to potentially infect 1.4 million persons in Liberia and Sierra Leone by January 2015 (“Questions and Answers”, 2014). Thankfully this worst case scenario did not occur and we may be experiencing natural burn out of the outbreak along …

The Kynurenine Pathway Of Tryptophan Catabolism And Aids-Associated Kaposi's Sarcoma In Africa, Helen Byakwaga, Peter W. Hunt, Miriam Laker-Oketta, David V. Glidden, Yong Huang, Bosco M. Bwana, Rain Mocello, John Bennett, Victoria Walusansa, Sheila C. Dollard, David R. Bangsberg, Edward K. Mbidde, Jeffrey N. Martin

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background—Other than Kaposi's sarcoma (KS)-associated herpesvirus and CD4+ T cell lymphopenia, the mechanisms responsible for KS in the context of HIV are poorly understood. One recently explored pathway of HIV pathogenesis involves induction of the enzyme indoleamine 2,3 dioxygenase-1 (IDO), which catabolizes tryptophan into kynurenine and several other immunologically active metabolites that suppress T cell proliferation. We investigated the role of IDO in the development of KS in HIV disease.

Methods—In a case-control study among untreated HIV-infected Ugandans, cases were adults with KS and controls were without KS. IDO activity was assessed by the ratio of plasma kynurenine to tryptophan …

Exploring The Pathophysiological Concepts Of Ebola Virus, Andrew T. Wasson

Nursing Student Class Projects (Formerly MSN)

The Ebola virus is a member of the filoviridae family. Five distinctive species of ebolavirus have been identified, four of which are known to cause disease in humans (Martines, Ng, Greer, Rollin, and Zaki, 2014). The specific species known to cause disease in humans are Zaire, Sudan, Ivory Coast, and Bundibugyo (Bray & Chertow, 2014). Bah et al. (2015) report that the Zaire ebolavirus (EBOV) was the cause of the most recent West African outbreak and carries the highest human mortality rate among the five known species, with up to 90% of cases being fatal. Ebola is a filamentous, enveloped, …

Chikungunya Virus: More Than A Mosquito Bite, Abigail Shaw

Nursing Student Class Projects (Formerly MSN)

Chikungunya fever is a viral infection caused by the Chikungunya virus (CHIKV). Although seldom fatal, CHIKV causes high fevers, polyarthralgia, and rash. The mosquito-borne virus has spread rapidly in the last ten years, causing over three million cases of CHIKV worldwide (Powers, 2015). The recent outbreak initiated in Africa and the islands of the Indian Ocean in 2004 has quickly spread to Asia, Europe and the Americas (CDC, 2015). According to the CDC (2015), until 2014, cases in the United States had only been linked to foreign travel outside of the Americas. As the outbreak has grown, cases of local …

What You Need To Know About Hiv/Aids, Lauren Mcclain

Nursing Student Class Projects (Formerly MSN)

Thirty years ago, the human immunodeficiency virus (HIV) was recognized as the cause of acquired immune deficiency syndrome (AIDS). Since that time, HIV/AIDS continues to be an ongoing problem worldwide. Even with persistent public heath campaigns and advancements in antiretroviral therapy, HIV/AIDS remains a major cause of global morbidity and mortality (Aggleton, Yankah, & Crewe, 2011). Although the annual number of new HIV/AIDS infections has remained stable, the number of people living with HIV/AIDS has continued increased. In the United States alone, the Centers of Disease Control and Prevention (CDC) estimates that 1,201,100 people are living with HIV infection, in …

Chikungunya Virus: A Case Study Of The Emerging Vector-Borne Disease, Lindsay D. Sullivan

Nursing Student Class Projects (Formerly MSN)

The Chikungunya virus (CHIKV) has spread like a wildfire in the Americas. Since its emergence in Sub-Saharan Africa as early at the 18th century, CHIKV has caused many isolated outbreaks in Africa, Southeast Asia, and Australia. Over the last decade, the vector-borne disease has inflicted millions of people on islands in the Indian Ocean, India, and now the Americas with the aid of viral mutations and international travel (Weaver and Lecuit, 2015). The first case of local CHIKV transmission in the Western Hemisphere was fairly recent. On the island of St. Martin in October 2013, an individual carrying an Asian …

Syphilis ‘The Great Imitator’, Leslie Gompf

Nursing Student Class Projects (Formerly MSN)

Syphilis, a sexually transmitted disease, which is seen in many different patient populations, is on the rise in the United States. According to Chan et al. (2015), “In 2012, the Rhode Island Department of Health (RIDOH) reported 68 cases of infectious syphilis, a 300% increase from 2006. This trend is observed across the country.” More recently if you live in the Columbus area you may have seen an increasing number of billboards focused directly on testing for sexually transmitted diseases and markedly focused on syphilis. Syphilis can affect patient populations across genres, ethnicities and socioeconomic backgrounds. Which in turn makes …

Congenital Cytomegalovirus (Cmv), Patty Fleming

Nursing Student Class Projects (Formerly MSN)

Cytomegalovirus (CMV) is a common herpes virus infection that is usually harmless and belongs to a group of herpes viruses that includes the herpes simplex viruses, varicella-zoster virus (which causes chickenpox and shingles), and the Epstein-Barr virus (which causes infectious mononucleosis). Once CMV is in a person's body, it stays there throughout their life. (Centers for Disease Control and Prevention, 2010). CMV is shed in various bodily secretions, especially urine and saliva (Congenital Cytomegalovirus Foundation, 2014). According to the Centers for Disease Control and Prevention (CDC), the majority of otherwise healthy children and adults infected with CMV are asymptomatic while …

Siedner, Data Santorino, Alexander J. Lankowski, Michael Kanyesigye, Mwebesa B. Bwana, Jessica E. Haberer, David R. Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Up to 50 % of HIV-infected persons in sub-Saharan Africa are lost from care between HIV diagnosis and antiretroviral therapy (ART) initiation. Structural barriers, including cost of transportation to clinic and poor communication systems, are major contributors.

Methods: We conducted a prospective, pragmatic, before-and-after clinical trial to evaluate a combination mobile health and transportation reimbursement intervention to improve care at a publicly operated HIV clinic in Uganda. Patients undergoing CD4 count testing were enrolled, and clinicians selected a result threshold that would prompt early return for ART initiation or further care. Participants enrolled in the pre-intervention period (January – …

Effects Of Antiretroviral Therapy On Kaposi’S Sarcoma–Associated Herpesvirus (Kshv) Transmission Among Hiv-Infected Zambian Children, Landon Olp, Veenu Minhas, Clement Gondwe, Chipepo Kankasa, Janet M. Wojcicki, Charles Mitchell, John T. West, Charles Wood

Nebraska Center for Virology: Faculty Publications

Background: The risk of Kaposi’s sarcoma–associated herpesvirus (KSHV) acquisition among children is increased by HIV infection. Antiretroviral therapy (ART) was recently made widely available to HIV-infected children in Zambia. However, the impact of early ART on KSHV transmission to HIV-infected children is unknown.

Methods: We enrolled and followed a cohort of 287 HIV-exposed, KSHV-negative children under 12 months of age from Lusaka, Zambia, to identify KSHV seroconversion events. Potential factors associated with KSHV infection—with an emphasis on HIV, ART, and immunological measures—were assessed through structured questionnaires and blood analyses. Incidence rate, Kaplan- Meier, and multivariable Cox regression models were used …

This cross-sectional, comparative study, investigated the self-reported sexual behaviors of sexually active older African Americans. The nonrandom sample (N = 78) included single African American men (59%) and women (41%), 50-74 years of age. Participants were recruited from various community sites, and data were collected with a standard sexual history questionnaire. Participants reported practicing risky behaviors such having unprotected oral, anal, and vaginal sex (96.5%), and having multiple sex partners (37.2%). There were several significant gender differences such …

Cationic Cell-Penetrating Peptides Are Potent Furin Inhibitors, Bruno Ramos-Molina, Adam N. Lick, Amir Nasrolahi Shirazi, Donghoon Oh, Rakesh Tiwari, Naglaa Salem El-Sayed, Keykavous Parang, Iris Lindberg

Pharmacy Faculty Articles and Research

Cationic cell-penetrating peptides have been widely used to enhance the intracellular delivery of various types of cargoes, such as drugs and proteins. These reagents are chemically similar to the multi-basic peptides that are known to be potent proprotein convertase inhibitors. Here, we report that both HIV-1 TAT47-57 peptide and the Chariot reagent are micromolar inhibitors of furin activity in vitro. In agreement, HIV-1 TAT47-57 reduced HT1080 cell migration, thought to be mediated by proprotein convertases, by 25%. In addition, cyclic polyarginine peptides containing hydrophobic moieties which have been previously used as transfection reagents also exhibited potent furin inhibition in vitro …
