Evaluating The Effectivesness Of Information Sources Regarding Hiv Among Gold Miners In Quảng Nam, Noah Landesberg

Independent Study Project (ISP) Collection

Young migrant males in strenuous manual labor environments represent a high-­‐risk population for the transmission of HIV/AIDS. In Vietnam, gold miners are representative of this high-­‐risk population. Phước Sơn district, Quảng Nam province is home to much of Vietnam’s mining activity and has a comparatively high rate of HIV. Previous studies have been done on HIV/AIDS prevalence in Quảng Nam as well as related knowledge and practices. This analysis of a 2014 questionnaire examines the effects of varying information sources on HIV/AIDS knowledge. The sample of workers was mostly male and between 25 and 49 years old. Migrants made up …

Evaluating Current Management Of Drug-Resistanttuberculosis In Mumbai, India, Meryl Kus

Independent Study Project (ISP) Collection

This research was aimed at analyzing the current state of drug resistant tuberculosis in Mumbai and how effectively different actors in the realm of public health are managing DR-TB. The methods for this project involved a variety of semi-structured interviews as well as field observation. Key findings show a very present and largely negative private sector influence, effective NGO models for disease control, a burden of DR-TB/HIV comorbidity, and a rapid increase to transmission-based spread of DR-TB. Key implications of conclusions include the necessity of increasing the private sector’s compliance with WHO standards, adaptation of community and education based NGO …

Comparison Of Self-Reported Alcohol Consumption To Phosphatidylethanol Measurement Among Hiv-Infected Patients Initiating Antiretroviral Treatment In Southwestern Uganda, Francis Bajunirwe, Jessica E. Haberer, Yap Boum Ii, Peter Hunt, Rain Mocello, Jeffrey Martin, David Bangsberg, Judith A. Hahn

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Alcohol consumption among HIV-infected patients may accelerate HIV disease progression or reduce antiretroviral therapy adherence. Self-reported alcohol use is frequently under-reported due to social desirability and recall bias. The aim of this study was to compare self-reported alcohol consumption to phosphatidylethanol (PEth), a biomarker of alcohol consumption, and to estimate the correlation between multiple measures of self-reported alcohol consumption with PEth.

Methods: The Uganda AIDS Rural Treatment Outcomes (UARTO) cohort is located in southwestern Uganda and follows patients on ART to measure treatment outcomes. Patients complete standardized questionnaires quarterly including questions on demographics, health status and alcohol consumption. Baseline …

Autoimmune Susceptibility Imposed By Public Tcrβ Chains, Yunqian Zhao

Theses and Dissertations (ETD)

The major histocompatibility complex (MHC) is the strongest genetic risk factor for autoimmunity. It acts together with a corresponding TCR repertoire, yet, considering the extent of the repertoire's diversity, how this imposes disease susceptibility on a population is not well understood. We address the hypothesis that shared or public TCR, those present in most individuals, modulate autoimmune risk. High resolution analyses of autoimmune encephalomyelitis-associated T-cell receptor β chain (TCRβ) showed preferential utilization of public TCR sequences, implicating them in pathogenesis. Disease-associated public TCRβ, when transgenically expressed in association with endogenously rearranged T-cell receptor α chain (TCRα), could further endow unprimed …

Can Mhealth Improve Risk Assessment In Underserved Populations? Acceptability Of A Breast Health Questionnaire App In Ethnically Diverse, Older, Low-Income Women., Carolina Bravo, Cristina O’Donoghue, Celia P. Kaplan, Judith Luce, Elissa Ozanne

Journal of Health Disparities Research and Practice

Background: Use of mobile health (mHealth) tools has expanded rapidly but little research has been done on its acceptability by low-income, diverse, older patient populations.

Objective: To assess the attitudes of a diverse group of underserved women on the acceptability and usability of mHealth tools in a clinical setting using a breast health questionnaire application (app) at a public hospital mammography clinic.

Methods: Semi-structured interviews were conducted in a breast-imaging center of an urban safety net institution from July-August 2012. Interviews included pre- and post-questions. Women completed the Athena breast health questionnaire app on an iPad and were asked about …

Latino Men Managing Hiv: An Appraisal Analysis Of Intersubjective Relations In The Discourse Of Five Research Interviews, Will Caston

Dissertations and Theses

Latino men, particularly those who have sex with other men, have been disproportionately affected by HIV/AIDS. Scholars have sought for nearly two decades to understand how various social and cultural factors in the Latino community exacerbate HIV risk among these men. Although following the advent of life-sustaining medications in 1996, HIV is often regarded as a manageable chronic illness, as opposed to a death sentence, scant attention has been devoted to how HIV-positive Latino men experience managing the illness. Among studies that have focused on HIV-positive persons' illness management, few Latino men have participated.

Using the Appraisal framework from Hallidayan …

What Is Pfapa And Why Does It Matter?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

PFAPA, the syndrome of periodic fever, aphthous stomatitis, pharyngitis and cervical lymphadentitis, is an uncommon disease of episodic immune dysregulation that usually begins in early childhood. Symptoms occur at regular, predictable intervals, with healthy periods in between, and generally include the namesake signs and various other constitutional symptoms such as fever and fatigue. The etiology is unknown and there is no definitive diagnostic test or treatment. Uncertainty during the period of searching for a diagnosis may be disconcerting to the family and the clinician. Single-dose prednisone is effective for resolving the fever of PFAPA episodes within just a few hours, …

Recurrent Aphthous Stomatitis: Diagnosis And Management In Primary Care, Jillian Hudson

Journal of Patient-Centered Research and Reviews

Recurrent aphthous stomatitis (canker sores) is a very common oral condition that remains incompletely understood. Presentation has been well-classified into minor, major or herpetiform subcategories based on clinical features, but exact etiology is unknown. Because etiology is unclear, treatments are primarily empiric and aimed at symptom reduction rather than prevention or cure. However, there are several methods, both topical and systemic, that can be easily and affordably utilized in the primary care setting.

Although scale-up of antiretroviral therapy (ART) since 2005 has contributed to a decline of about 30% in the global annual number of human immunodeficiency (HIV)–related deaths and declines in global HIV incidence, estimated annual HIV-related deaths among adolescents have increased by about 50%, and estimated adolescent HIV incidence has been relatively stable. In 2012, an estimated 2,500 (40%) of all 6,300 daily new HIV infections occurred among persons aged 15–24 years. Difficulty enrolling adolescents and young adults in ART and high rates of loss to follow-up (LTFU) after ART initiation might be contributing to mortality and HIV incidence in this …

OHSU-PSU School of Public Health Faculty Publications and Presentations

A qualitative assessment of Kenyan men who have sex with men taking daily and intermittent oral HIV preexposure prophylaxis (PrEP) found stigma, sex work, mobility, and alcohol impacted adherence. We analyzed quantitative data from the same cohort to explore different definitions of intermittent adherence. Volunteers were randomized to daily emtricitabine/tenofovir or placebo, or intermittent (prescription: Mondays/Fridays/after sex, maximum1 dose/day)emtricitabine/tenofovir or placebo (2:1:2:1), and followed for 4 months. By electronic monitoring, median adherence for daily dosing was 80 %. Median adherence for intermittent dosing was 71 % per a ‘‘relaxed’’ definition (accounting for off-prescription dosing) and 40 % per a ‘‘strict’’ …

Smarter Vaccine Design Will Circumvent Regulatory T Cell-Mediated Evasion In Chronic Hiv And Hcv Infection, Leonard Moise, Frances Terry, Andres H. Gutierrez, Ryan Tassone, Phyllis Losikoff, Stephen H. Gregory, Chris Bailey-Kellogg

Dartmouth Scholarship

Despite years of research, vaccines against HIV and HCV are not yet available, due largely to effective viral immunoevasive mechanisms. A novel escape mechanism observed in viruses that cause chronic infection is suppression of viral-specific effector CD4(+) and CD8(+) T cells by stimulating regulatory T cells (Tregs) educated on host sequences during tolerance induction. Viral class II MHC epitopes that share a T cell receptor (TCR)-face with host epitopes may activate Tregs capable of suppressing protective responses. We designed an immunoinformatic algorithm, JanusMatrix, to identify such epitopes and discovered that among human-host viruses, chronic viruses appear more human-like than viruses …

Myasthenia Gravis: A Closer Look, Erin L. Ricker

Nursing Student Class Projects (Formerly MSN)

Myasthenia gravis (MG) is a rare, chronic autoimmune disease that affects the neurotransmitter acetylcholine and the acetylcholine receptors at the neuromuscular junction (Mestecky, 2013). MG causes fluctuating skeletal muscle weakness and fatigue. According to the Myasthenia Gravis Foundation of America (MGFA) (2010), 20 per 100,000 patients are diagnosed with MG, although researchers believe several more patients are misdiagnosed or missed entirely. Several neurological disorders have similar clinical presentations to MG making it difficult for inexperienced practitioners to identify and properly diagnose patients. Patients are often misdiagnosed and delayed proper treatment for one to two years after initial presentation of symptoms …

Global Burden Of Tuberculosis, Diana Moses

Nursing Student Class Projects (Formerly MSN)

Tuberculosis (TB) is a major health concern not only in the United States, but in the entire world. TB is an airborne communicable infection which has affected human beings from immemorial times, evidenced by TB being found in the skeletal remains of ancient mummies (Gough & Kaufman, 2011). There are many patho physiological events in TB that concern the entire body, especially the respiratory and immunological systems. According to Knechel, TB prevalence is rising due to the increased number of patients infected with HIV, bacterial resistance to medications, increased international travel and immigration from countries with high prevalence of TB, …

Steven-Johnson’S Syndrome/Toxic Epidermal Necrolysis, Lindsey Grant

Nursing Student Class Projects (Formerly MSN)

Steven-Johnson’s Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are both diseases mediated by hypersensitive immune reactions resulting in “full thickness epidermal necrosis” characterized by skin detachment. However, in SJS, there is only 10% skin surface area involvement whereas in TEN, over 30% of the skin becomes detached. TENS has a 50% mortality rate. (East-Innis & Thompson, 2013, p. 590) Why Chosen: SJS/TEN is a rare but extremely fatal disease. Initially, it is often mistaken as a simple allergic reaction to a new medication or environmental exposure because both cause truncal rashes and fevers. However, simple allergic reactions occur within days …

Effects Of 5-Aza-2' Deoxycitidine And Sulforaphane On Major Histocompatibility Complex (Mhc) Classes I And Ii Surface Expression In Human Acute T-Cell Leukemia Cell Jurkat, Ali Salam Abdullah Ms

All Student Scholarship

The immune system cells recognize and kill cancer cells by engaging the tumor antigens on the surfaces of cancer cells presented by the Major Histocompatibility Complex (MHC). Cancer cells can escape from immune system cells recognition and/or killing by down-regulating the MHC expression through genetic or epigenetic mechanisms.

Understanding Treatment Refusal Among Adults Presenting For Hiv-Testing In Soweto, South Africa: A Qualitative Study, Ingrid T. Katz, Janan Dietrich, Gugu Tshabalala, Thandekile Essien, Kathryn Rough, Alexi A. Wright, David Bangsberg, Glenda E. Gray, Norma C. Ware

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV treatment initiatives have focused on increasing access to antiretroviral therapy (ART). There is growing evidence, however, that treatment availability alone is insufficient to stop the epidemic. In South Africa, only one third of individuals living with HIV are actually on treatment. Treatment refusal has been identified as a phenomenon among people who are asymptomatic, however, factors driving refusal remain poorly understood. We interviewed 50 purposively sampled participants who presented for voluntary counseling and testing in Soweto to elicit a broad range of detailed perspectives on ART refusal. We then integrated our core findings into an explanatory framework. Participants described …

Racial And Ethnic Disparities In Time To Cure Of Incontinence Present At Nursing Home Admission, Donna Z. Bliss, Olga Gurvich, Kay Savik, Lynn Eberly, Susan Harms, Jean F. Wyman

Journal of Health Disparities Research and Practice

Abstract

As many as half of older people that are admitted to nursing homes (NHs) are incontinent of urine and/or feces. Not much is known about the rate of cure of incontinence present at NH admission, but available reports suggest the rate is low. There have been racial and ethnic disparities in incontinence treatment, but the role of disparities in the cure of incontinence is understudied. Using the Peters-Belson method and multilevel predictors, our findings showed that there were disparities in the time to cure of incontinence for Hispanic NH admissions. A significantly smaller proportion of older Hispanic admissions were …

Persistent Hiv-Related Stigma In Rural Uganda During A Period Of Increasing Hiv Incidence Despite Treatment Expansion, Brian T. Chan, Sheri D. Weiser, Yap Boum Ii, Mark J. Siedner, Rain Mocello, Jessica E. Haberer, Peter Hunt, Jeffrey N. Martin, Kenneth H. Mayer, David Bangsberg, Alexander C. Tsai

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objective—Program implementers have argued that the increasing availability of anti-retroviral therapy (ART) will reduce the stigma of HIV. We analyzed data from Uganda to assess how HIV-related stigma has changed during a period of ART expansion.

Design—Serial cross-sectional surveys.

Methods—We analyzed data from the Uganda AIDS Rural Treatment Outcomes (UARTO) study during 2007-2012 to estimate trends in internalized stigma among people living with HIV (PLHIV) at the time of treatment initiation. We analyzed data from the Uganda Demographic and Health Surveys (DHS) from 2006 and 2011 to estimate trends in stigmatizing attitudes and anticipated stigma in the general population. We …

Delayed Switch Of Antiretroviral Therapy After Virologic Failure Associated With Elevated Mortality Among Hiv-Infected Adults In Africa, Maya L. Petersen, Linh Tran, Elvin H. Geng, Steven J. Reynolds, Andrew Kambugu, Robin Wood, David Bangsberg, Constantin T. Yiannoutsos, Steven G. Deeks, Jeffrey N. Martin

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objective—Routine monitoring of plasma HIV RNA among HIV-infected patients on antiretroviral therapy (ART) is unavailable in many resource-limited settings. Alternative monitoring approaches correlate poorly with virologic failure and can substantially delay switch to second-line therapy. We evaluated the impact of delayed switch on mortality among patients with virologic failure in Africa.

Design—A cohort.

Methods—We examined patients with confirmed virologic failure on first-line non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens from four cohorts with serial HIV RNA monitoring in Uganda and South Africa. Marginal structural models aimed to estimate the effect of delayed switch on mortality in a hypothetical trial in which …

High Medication Adherence During Periconception Periods Among Hiv-1–Uninfected Women Participating In A Clinical Trial Of Antiretroviral Pre-Exposure Prophylaxis, Lynn T. Matthews, Renee Heffron, Nelly R. Mugo, Craig R. Cohen, Craig W. Hendrix, Connie Celum, David Bangsberg, Jared M. Baten

OHSU-PSU School of Public Health Faculty Publications and Presentations

Introduction: Pre-exposure prophylaxis (PrEP) may be an important safer conception strategy for HIV-1–uninfected women with HIV-1–infected partners. Understanding medication adherence in this population may inform whether PrEP is a feasible safer conception strategy.

Methods: We evaluated predictors of pregnancy and adherence to study medication among HIV-1–uninfected women enrolled in a randomized placebo-controlled trial of PrEP among African HIV-1– serodiscordant couples. Participants were counseled on HIV-1 risk reduction, contraception, and adherence and tested for pregnancy at monthly study visits. Pill counts of dispensed drug were performed and, at a subset of visits, plasma was collected to measure active drug concentration.

Results: …

A Rhetorical Analysis Of The Rethinking Aids Website, Jennifer Dettmann

Journal of Undergraduate Research at Minnesota State University, Mankato

A group of scientists known as the Group for Scientific Reappraisal of the HIV-AIDS hypothesis created a web site title, Rethinking AIDS. The group behind the web site argues that AIDS is not a sexually transmitted disease. They even question the existence of the virus entity. My analysis is driven by the critical question: Does the web site construct a reality that affectively alters our perception of HIV-AIDS? In order to answer this question, Goodnight and Poulakos 1981 article, Conspiracy rhetoric: from pragmatism to fantasy to public discourse (Western Journal of Speech), will be utilized.

Empiric Deworming And Cd4 Count Recovery In Hiv-Infected Ugandans Initiating Antiretroviral Therapy, Alexander J. Lankowski, Alexander C. Tsai, Michael Kanyesigye, Mwebesa B. Bwana, Jessica E. Haberer, Megan Wenger, Jeffrey N. Martin, David Bangsberg, Peter W. Hunt, Mark J. Siedner

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: There is conflicting evidence on the immunologic benefit of treating helminth co-infections (‘‘deworming’’) in HIV-infected individuals. Several studies have documented reduced viral load and increased CD4 count in antiretroviral therapy (ART) naive individuals after deworming. However, there are a lack of data on the effect of deworming therapy on CD4 count recovery among HIV-infected persons taking ART.

Methodology/Principal Findings: To estimate the association between empiric deworming therapy and CD4 count after ART initiation, we performed a retrospective observational study among HIV-infected adults on ART at a publicly operated HIV clinic in southwestern Uganda. Subjects were assigned as having received …

Crankshaw, Cecilia Milford, Fortunate N. Mosery, Ross Greener, Christina Psaros, Steven A, Safren, David Bangsberg, Jennifer A. Smit

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Implementation of safer conception strategies requires knowledge of partner HIV-serostatus. We recruited women and men in a high HIV-prevalence setting for a study to assess periconception risk behavior among individuals reporting HIV-serodiscordant partnerships. We report screening data from that study with the objective of estimating the proportion of individuals who are aware that they are in an HIV-serodiscordant relationship at the time of conception.

Methods: We screened women and men attending antenatal and antiretroviral clinics in Durban, South Africa for enrollment in a study of periconception risk behavior among individuals with serodiscordant partners. Screening questionnaires assessed for study eligibility …

The Mucosal Expression Pattern Of Interferon-Ε In Rhesus Macaques, Andrew Demers, Guobin Kang, Fangrui Ma, Wuxun Lu, Zhe Yuan, Yue Li, Mark Lewis, Edmundo N. Kraiselburd, Luis Montaner, Qingsheng Li

Qingsheng Li Publications

Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain uncertain. In addition, the expression of IFN-ε in Indian rhesus macaques (Macaca mulatta) has not been reported. Here, we analyzed IFN-ε expression in multiple mucosal sites of uninfected or SIV-infected Indian rhesus macaques using IHCS. We report for the first time the …

Will Hiv Vaccination Reshape Hiv Risk Behavior Networks? A Social Network Analysis Of Drug Users' Anticipated Risk Compensation, April M. Young, Daniel S. Halgin, Ralph J. Diclemente, Claire E. Sterk, Jennifer R. Havens

Epidemiology and Environmental Health Faculty Publications

Background

An HIV vaccine could substantially impact the epidemic. However, risk compensation (RC), or post-vaccination increase in risk behavior, could present a major challenge. The methodology used in previous studies of risk compensation has been almost exclusively individual-level in focus, and has not explored how increased risk behavior could affect the connectivity of risk networks. This study examined the impact of anticipated HIV vaccine-related RC on the structure of high-risk drug users' sexual and injection risk network.

Methods

A sample of 433 rural drug users in the US provided data on their risk relationships (i.e., those involving recent unprotected sex …

Decreases In Self-Reported Alcohol Consumption Following Hiv Counseling And Testing At Mulago Hospital, Kampala, Uganda, Judith A. Hahn, Robin Fatch, Rhoda K. Wanyenze, Steven Baveewo, Moses R. Kamya, David Bangsberg, Thomas J. Coates

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Alcohol use has a detrimental impact on the HIV epidemic, especially in sub-Saharan Africa. HIV counseling and testing (HCT) may provide a contact opportunity to intervene with hazardous alcohol use; however, little is known about how alcohol consumption changes following HCT.

Methods: We utilized data from 2056 participants of a randomized controlled trial comparing two methods of HCT and subsequent linkage to HIV care conducted at Mulago Hospital in Kampala, Uganda. Those who had not previously tested positive for HIV and whose last HIV test was at least one year in the past were eligible. Participants were asked at …

Journal of Health Disparities Research and Practice

Creating health equity and eliminating health disparities are considered national priorities for improving the health of Americans (U.S. Department of Health and Human Services, n.d.). Health disparities are a primary public health concern, yet are complex phenomena and challenging to research (Harper & Lynch, 2005). The National Institute on Minority Health and Health Disparities (NIMHD), under the National Institute of Health (NIH), is committed to finding solutions to achieve this goal through the creation of interdisciplinary Centers of Excellence. In 2009, the University of South Florida (USF) and Moffitt Cancer Center (Moffitt) received a NIMHD Exploratory Center of Excellence award …

Fty720 (Fingolimod) Provides Insight Into The Molecular Mechanisms Of Multiple Sclerosis, Madelyn Elizabeth Crawford

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Multiple sclerosis (MS) is a neurodegenerative disorder caused by a prolonged immune- mediated inflammatory response that targets myelin. Nearly all of the drugs approved for the treatment of MS are general immunosuppressants or only function in symptom management. The oral medication fingolimod, however, is reported to have direct therapeutic effects on cells of the central nervous system in addition to immunomodulatory functions. Fingolimod is known to interact with sphingosine-1-phosphate (S1P) receptors, and the most widely- accepted theory for its mechanism of action is functional antagonism of the receptor. This review examines significant neuromodulatory effects achieved by functional antagonism of the …

Nanotoxicity In Cells Of The Immune System, Jonathan J. Pelc

Science Scholars

Nanoparticles (NPs) provide a new medical approach to drug therapy. As with every new approach, safety precautions need to be taken, and the immediate and long-term effects for many NPs are still unclear. When administering a medical treatment into the human body, the first issue that needs to be addressed is host detection of the medicine and inflammation as a possible result of the treatment. If a new NP treatment causes inflammation before it releases its medicine, that treatment may be ineffective, even damaging to the patient. Small metallic and organic particles have been shown to elicit an inflammatory responses …
