Investigating Virus Clearance Via Ph Inactivation During Biomanufacturing, Wenbo Xu

Biomedical Engineering Undergraduate Honors Theses

In the processing of biopharmaceuticals, viral clearance and viral safety are important for the development of monoclonal antibodies. Murine xenotropic leukemia virus (XMuLV) is one of the retroviruses, recommended by Food and Drug Administration (FDA) as a model virus for viral clearance via inactivation from therapeutics derived from Chinese hamster ovary cells (CHO). A robust and effective method was investigated to clear or inactivate endogenous viruses by low pH inactivation. The effects of different conductivity and inactivated time on XMuLV clearance was determined. Acetate buffer was prepared with different conductivity, and 2% XMuLV was spiked into acetate buffer. XMuLV virus …

Preventing Infectious Hematopoietic Necrosis In Salmonid Fish Along The Columbia River Basin, Whitney L. Wright

OHSU-PSU School of Public Health Annual Conference

Infectious hematopoietic necrosis virus (IHNV) is a member of the Rhabdoviridae family and causes infectious hematopoietic necrosis (IHN) disease in many salmonid species during the juvenile or “fry” stage of life. IHNV is endemic to Western North America and occurs in the Columbia River Basin, where Steelhead and Chinook salmon are the most abundant IHNV-vulnerable species. IHNV can cause an epidemic in wild or farmed stocks, killing 90-95 percent of the fish it infects. Transmission is currently understood to occur by direct exposure through the gills, and the virus is shed typically from asymptomatic or clinically ill carrier adults at …

Risky Business: Millennials’ Protection Motivation Factors For Norovirus Outbreaks On College Campuses, Dylan Conrad Martinez

Graduate Theses and Dissertations

The risk and severity of hNoV transmission is obscurely recognized to foodservice millennial customers. Most commonly associated with cruise ships, consumers are not aware of its full potential to strike at other locations, especially college campuses. For the foodservice industry and the university community, it is imperative that a proactive method for increasing millennials’ motivation to practice mitigation methods emerges to reduce future hNoV outbreaks on college campuses. Research has shown that students can play a major role in the spread of hNoV on college campuses. Therefore, the purpose of these studies is to examine motivations for health protective behaviors …

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 …

Integrating Students Into Interdisciplinary Health And Health Disparities Research Teams, Tanya M. Coakley, Allyson Kelley, Robin Bartlett, Terri Shelton, Schenita D. Randolph, Debra C. Wallace

Journal of Health Disparities Research and Practice

Major initiatives by the U.S. Department of Health and Human Services as well as the World Health Organization have produced a large and compelling body of evidence on how to reduce health disparities, which entails having a clear understanding of how social factors shape health and healthcare outcomes. Specifically, there is a need for healthcare professionals to understand social determinants of health (e.g., low socioeconomic status, lack of health insurance, and poor education) and how these lead to disparities in health for people of minority racial and ethnic groups. Little is known about how students are developed as health disparities …

Barriers To Addressing Hiv-Associated Neurocognitive Disorder (Hand): Community-Based Service Provider Perspectives, Renato M. Liboro, Francisco Ibanez-Carrasco, Sean B. Rourke, Andrew Easton, Claudia Medina, Daniel Pugh, Allan Rae, Lori E. Ross, Paul A. Shuper

Psychology Faculty Research

HIV-Associated Neurocognitive Disorder (HAND) is an emergent public health issue in developed countries. Consequently, people living with HIV who experience HAND will increasingly require support from community-based HIV service providers. The objective of our qualitative study was to identify barriers service providers face in addressing HAND among people living with HIV. Thirty-three providers from 22 AIDS service organizations across Ontario, Canada, were interviewed. Using thematic analysis, three types of barriers were identified: (a) personal/professional, (b) service access, and (c) systemic. This paper draws attention to HAND-related obstacles that service providers encounter in their work and presents options to overcome them.

There are many interventions that have been tried in Tanzania. In the last year there have been over 50,000 new cases of HIV/Aids in Tanzania. The goal is to main those numbers go down dramatically in the coming years. The two most common interventions are trying to educate this subject at a young age and provide condoms to the population. They tried giving condoms out to the people of Tanzania …

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

Furmanek, Conner English, Mary Bishop, Cathy Spencer, Daniel Truelove, Julio A. Ramirez, Anupama Raghuram, Paula Peyrani

Faculty and Staff Scholarship

Background

Controversy still exists regarding gender differences in virologic response between treatment-na•ve HIV-infected individuals. The objective of this study was to evaluate gender difference in virologic and immunologic response to antiretroviral therapy in treatment-na•ve HIV-infected individuals. Methods

This was a retrospective, observational study of treatment-na•ve HIV-infected individuals managed at the 550 clinic who started antiretroviral therapy (ART) between January 1st, 2010 and December 31, 2015. Patients with available viral load and CD4 counts before and one year after initiating ART were included in this study. Virologic suppression was defined as < 48 HIV-1 RNA copies/mL, and mmunologic recovery was defined as a CD4 count increase of at least 150 cells/mm3. Dichotomous variables were reported in number and percentages and analyzed using Chi-squared tests and Fisher’s exact (whichever was appropriate). Continuous variables were reported as median and interquartile range (IQR) and analyzed using Wilcox rank-sum tests. Multivariate analyses performed were logistic regressions with adjustment for other covariates. P value <0.05 was considered statistically significant. R version 3.3.2 was used for the statistical analysis. Results

A total of 70 women and 90 men were included …

Risk For Cardiovascular Disease In Blacks With Hiv/Aids In America: A Systematic Review And Meta-Analysis, Calvin Odhiambo, Jessica Davis, Bernard Omolo

Journal of Health Disparities Research and Practice

Cardiovascular disease (CVD) related to HIV infection is becoming a major public health concern in the United Stated. Epidemiologic studies show that prolonged use of Highly Active Antiretroviral Therapy, HIV/AIDS itself, and a combination of traditional vascular risk factors increase the risk for CVD among people with HIV/AIDS. However, little is known about any racial disparities in the risk for CVD in the HIV/AIDS population. We conducted a systematic review and meta-analysis of literature on HIV/AIDS and CVD (June 1, 2010-July 31, 2014) through MEDLINE to examine whether and how HIV-positive African Americans are disproportionately affected by CVD compared to …

The Feminization Of Hiv/Aids In Yunnan, China, Leah Pinckney

Independent Study Project (ISP) Collection

The feminization of HIV is a global phenomenon in which more women are becoming HIV-positive. This not only has tragic consequences for those women but also signifies how HIV transmission in China is changing. Increased sexual transmission has given HIV the ability to move from at-risk groups, such as intravenous drug users and commercial sex workers, to the general population. Despite China’s improved health policies and programs about HIV, this situation poses a serious public health issue allowed to perpetuate because of societal problems surrounding gender. These problems are compounded by socioeconomic inequality brought upon by economic change. While much …

Women’S Views On The Challenges And Solutions In Preventing The Gendered Spread Of Hiv In Masxha, Cato Manor, Paige Mcmahon

Independent Study Project (ISP) Collection

Despite numerous national prevention efforts, South Africa remains at the epicenter of the HIV/AIDS epidemic. The burden of the epidemic is extremely heterogeneous, with province, race, gender, age, and socioeconomic status serving as key variables in determining HIV prevalence rates. Black African women are disproportionately affected by the epidemic, with those between the ages of 20 and 34 having an HIV prevalence rate of 31.6%, the highest in the country (Shisana et al., 2014). The purpose of this study was to engage with black African women about the challenges they believe women face in protecting themselves against HIV, and potential …

Japanese Encephalitis: Assessing Disease Risk Due To Landscape Factors At Multiple Scales, Julia E. Metelka

Theses and Dissertations (Comprehensive)

Japanese Encephalitis is a mosquito-borne disease and is the leading cause of viral encephalitis in Asia. In many Asian countries, the geographical distribution of JE is dependent on a variety of human-environment interactions that can be conceptualized as a complex social-ecological system. The JE transmission cycle is influenced by a few primary human-landscape factors; the abundance and the spatial configuration of rice paddy fields (which provide habitat for the vector), the distribution of pig farms (which position the virus' amplifying host), and the location of a susceptible human population. Our models integrate population dynamics, landscape characteristics, and weather variables that …

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

Preliminary Evaluation Of The Disease Surveillance System During Influenza Outbreaks Of Pandemic Scale, Eric Meisheri, Diana M. Prieto, Peter Holvenstot, Richard Vanenk

Frontiers in Public Health Services and Systems Research

In the United States it is currently unknown whether the influenza surveillance system is capable of producing timely and accurate data for case estimation during an outbreak of pandemic scale. This simulation provides a preliminary evaluation of the surveillance system’s ability to collect data and produce timely and accurate trends of cases confirmed with an influenza virus. For the evaluation, a computer-based simulation of the data-collection process was used, which was validated with real demographic and epidemiologic information. The results were analyzed to determine the most significant behavioral and operational factors influencing the data collection and to propose the exploration …

Strengthening The Detection Of And Early Response To Public Health Emergencies: Lessons From The West African Ebola Epidemic, Mark J. Siedner, Lawrence O. Gostin, Hilarie H. Cranmer, John D. Kraemer

Georgetown Law Faculty Publications and Other Works

Background

In the year since the World Health Organization (WHO) notified of an Ebola outbreak in West Africa, more than 24,000 cases have been reported and over 10,000 individuals have died. Moreover, countless non-Ebola deaths have occurred as a result of health system closings and an international aid effort in the $USD billions has been invested in control efforts. While the international response to the West African Ebola virus disease epidemic eventually exemplified the great potential of the global public health community, the protracted early response also revealed critical gaps, which likely resulted in exacerbation of the epidemic. It is …

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 …

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 …
