Ebola Scare And Measles Resurgence: Mandatory Isolation/Quarantine And Vaccination, Mark C. Aita Md, Takeem T. Ragland Ma

Journal of Health Ethics

Public outcry for radical isolation and quarantine policies followed the first Ebola diagnosis in the United States when Eric Duncan, upon his return home Oct 2014 from West Africa, then in the midst of a catastrophic Ebola epidemic, tested positive for Ebola. Likewise, the Dec 2014 Disneyland measles outbreak unleashed an angry backlash against parents who refused to have their children vaccinated; and there was public momentum to repeal all legal exemptions to mandatory vaccination of school children. This paper presents an ethical and legal analysis to adjudicate the issue which is at stake in both controversies; namely the inherent …

Polio Eradication And Health Systems In Karachi: Vaccine Refusals In Context, Svea Closser, Rashid Jooma, Emma Varley, Naina Qayyum, Sonia Rodrigues, Akasha Sarwar, Patricia Omidian

Section of Neurosurgery

Community and health worker engagement will be key to polio eradication in Karachi, Pakistan. In this study, the authors conducted participant observation, interviews, and a document review in SITE Town, Karachi, an area that in recent years has harbored poliovirus. SITE’s diverse population includes large numbers of internally displaced persons who are disproportionately affected by polio and are more likely than other populations to refuse the polio vaccine. Vaccine acceptance and worker motivation in SITE Town were shaped by the discrepancy in funding and attention for polio eradication campaigns as compared with routine services. Parental vaccine refusals stemmed from a …

The Germ Theory Of Dystopias: Fears Of Human Nature In 1984 And Brave New World, Clea D. Harris

Scripps Senior Theses

This project is an exploration of 20^th century dystopian literature through the lens of germ theory. This scientific principle, which emerged in the late 19^th century, asserts that microorganisms pervade the world; these invisible and omnipresent germs cause specific diseases which are often life threatening. Additionally, germ theory states that vaccines and antiseptics can prevent some of these afflictions and that antibiotics can treat others. This concept of a pervasive, invisible, infection-causing other is not just a biological principle, though; in this paper, I argue that one can interpret it as an ideological framework for understanding human existence …

Characterization Of Co-Circulating Swine Influenza A Viruses In North America And The Identification Of A Novel H1 Genetic Clade With Antigenic Significance, Tavis K. Anderson, Brian A. Campbell, Martha I. Nelson, Nicola S. Lewis, Alicia Janas Martindale, Mary Lea Killian, Amy L. Vincent

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Multiple genetically and antigenically distinct hemagglutinin genes of the H1 and H3 influenza A virus (IAV) subtypes co-circulate in North American swine. This diversity has evolved by repeated transmission of IAVs from humans to swine and subsequent antigenic drift in swine. To understand the evolutionary dynamics of these diverse HA lineages in North American swine, we undertook a phylogenetic analysis of 1576 H1 and 607 H3 HA gene segments, as well as 834 N1 and 1293 N2 NA gene segments, and 2126 M gene segments. These data revealed yearly co-circulation of H1N1, H1N2, and H3N2 viruses, with three HA clades …

A Retrospective And Prospective Analysis Of The West African Ebola Virus Disease Epidemic: Robust National Health Systems At The Foundation And An Empowered Who At The Apex, Lawrence O. Gostin, Eric A. Friedman

Georgetown Law Faculty Publications and Other Works

The West African Ebola epidemic is a pivotal moment for the global health system. Just as the depth of the crisis ultimately spurred an unprecedented response, the failures of leadership demand innovative reforms. This analysis offers a template for these reforms, responding to the profound harms posed by fragile national health systems, delays in the international response, deficient resource mobilization, ill-defined responsibilities, and insufficient coordination. The scope of the reforms must address the failures evident in the Ebola response, as well as entrenched weaknesses that enabled the epidemic to reach its heights, transforming the existing inchoate, organically developed global health …

Kaposi Sarcoma Herpesvirus Induces Ho-1 During De Novo Infection Of Endothelial Cells Via Viral Mirna-Dependent And -Independent Mechanisms, Sara Botto, Jennifer Totonchy, Jean K. Gustin, Ashlee V. Moses

Pharmacy Faculty Articles and Research

Kaposi sarcoma (KS) herpesvirus (KSHV) infection of endothelial cells (EC) is associated with strong induction of heme oxygenase-1 (HO-1), a stress-inducible host gene that encodes the rate-limiting enzyme responsible for heme catabolism. KS is an angioproliferative tumor characterized by the proliferation of KSHV-infected spindle cells, and HO-1 is highly expressed in such cells. HO-1 converts the pro-oxidant, proinflammatory heme molecule into metabolites with antioxidant, antiinflammatory, and proliferative activities. Previously published work has shown that KSHV-infected EC in vitro proliferate in response to free heme in a HO-1-dependent manner, thus implicating virus-enhanced HO-1 activity in KS tumorigenesis. The present study investigated …

Combating Hiv/Aids In Marginalized Communities: Papua And West Papua Provinces, Indonesia, Bani Cheema

Master's Theses

My study focuses on foreign aid and local initiatives for HIV/AIDS prevention in eastern Indonesia using the provinces of Papua and West Papua as a case study. The two provinces are home to indigenous tribal groups that are socioeconomically marginalized and most affected by the epidemic. My research investigates behavior change communication as a principal strategy undertaken by multiple organizations for HIV/AIDS prevention in this region. I take a qualitative approach by examining the effectiveness of this strategy in local communities and by revealing social and cultural barriers that impede success. Obstacles that negatively impact prevention efforts include structural violence, …

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 …

Increasing Hpv Vaccination Rates Using Social Marketing Strategies, Sharon Wilson Catledge

Doctoral Projects

The human papillomavirus (HPV) is the most common sexually-transmitted infection (STI). Approximately 20 million Americans between the ages of 15 and 49 years currently have HPV with > 6.2 million new HPV infections estimated to occur each year. Yet, HPV vaccination rates remain relatively low. More than 40 strains of HPV are transmitted through genital contact during vaginal, anal, or oral sex and can infect males and females. In addition to causing genital warts, HPV is associated with cervical, vulvar, vaginal, anus, penile, and oropharyngeal cancers. In women, the most prominent type of cancer is cervical with > 12,000 diagnoses each year …

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 …

Sustained Adrenergic Signaling Promotes Cervical Cancer Progression, Nouara C. Sadaoui

Dissertations and Theses (Open Access)

Background: Chronic stress and sustained adrenergic signaling are known to promote tumor progression. The underlying mechanisms behind this process are not well understood. We examined the effects of sustained adrenergic signaling on cervical cancer progression through increased expression of HPV oncogenes, E6 and E7.

Materials and Methods: ADRβ expression levels were examined in patient-derived cervical cancer samples. We used an orthotopic model of cervical cancer to investigate the effects of restraint stress on tumor growth and metastasis. We evaluated the in vivo effects of a β-blocker, propranolol, and HPV E6/E7 siRNA. In vitro, ADRβ positive cervical cancer cells were …

Acanthamoeba Spp. As Reservoirs For Transmission Of Norovirus, Tun-Yun Hsueh

Graduate Theses and Dissertations

Human noroviruses (HuNoV) are the most common cause of foodborne disease outbreaks in the United States and the most common food commodities implicated in HuNoV outbreaks are leafy greens; however, the vehicle of transmission and point of contamination are often unknown. Here, we hypothesize that common free-living amoebae (FLA) ubiquitous in the environment may act as reservoirs of HuNoV and facilitate the transmission of these pathogens to fresh produce. The objective of this research was to first evaluate the interaction/association between HuNoV surrogates and Acanthamoeba by incubating them together and analyzing virus titer associated with amoeba through an 8 day …

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 …

Nucleoside Reverse Transcriptase Inhibitors Possess Intrinsic Anti-Inflammatory Activity, Benjamin J. Fowler, Bradley D. Gelfand, Younghee Kim, Nagaraj Kerur, Valeria Tarallo, Yoshio Hirano, Shoba Amarnath, Daniel H. Fowler, Marta Radwan, Mark T. Young, Keir Pittman, Paul Kubes, Hitesh Agarwal, Keykavous Parang, David R.

Pharmacy Faculty Articles and Research

Nucleoside reverse transcriptase inhibitors (NRTIs) are mainstay therapeutics for HIV that block retrovirus replication. Alu (an endogenous retroelement that also requires reverse transcriptase for its life cycle)–derived RNAs activate P2X7 and the NLRP3 inflammasome to cause cell death of the retinal pigment epithelium in geographic atrophy, a type of age-related macular degeneration. We found that NRTIs inhibit P2X7-mediated NLRP3 inflammasome activation independent of reverse transcriptase inhibition. Multiple approved and clinically relevant NRTIs prevented caspase-1 activation, the effector of the NLRP3 inflammasome, induced by Alu RNA. NRTIs were efficacious in mouse models of geographic atrophy, choroidal neovascularization, graft-versus-host disease, and sterile …
