Literature Review Of Covid-19 Biochemistry, Alexandra Allen

2020 Symposium Posters

SARS-CoV-2 is the virus responsible for the current pandemic. SARS-CoV-2 is a betacoronavirus with a genome that is 79.5% identical to SARS-CoV. The virus enters T lymphocytes using its spike protein with the human angiotension-converting enzyme 2 as its receptor. SARS-CoV-2 was found to have a unique peptide sequence that could contribute to the proteolytic cleavage of the spike protein, therefore potentially impacting host range and transmissibility. COVID-19 is diagnosed through a nasal swab SARS-CoV-2 RT-PCR assay and the most common symptoms appear to be fever, cough, and fatigue. The median amount of time an individual will be contagious with …

All Faculty Scholarship

This essay for the Regulatory Review's special series on Comparing Nations’ Responses to COVID-19 examines the early response to the pandemic in Portugal. The essay focuses on measures adopted in connection with the declarations of state of emergency and state of calamity, as well as the treatment of migrant populations throughout the pandemic.

Mapping Misinformation In The Coronavirus Outbreak, Ana Santos Rutschman

All Faculty Scholarship

The coronavirus outbreak has sent ripples of fear and confusion across the world. These sentiments—and our collective responses to the outbreak—are made worse by rampant misinformation surrounding the new strain of the virus, COVID-2019. In this post, I survey some of the most pervasive areas of tentacular coronavirus-related misinformation that has proliferated online -- as well as the responses of social media companies like YouTube, Facebook, Pinterest and TikTok that may ultimately prove inadequate given the magnitude of the problem.

The Case For Face Shields: Improving The Covid-19 Public Health Policy Toolkit, Timothy L. Wiemken, Ana Santos Rutschman, Robert Gatter

All Faculty Scholarship

As the United States battles the later stages of the first wave of COVID-19 and faces the prospect of future waves, it is time to consider the practical utility of face shields as an alternative or complement to face masks in the policy guidance. Without face shields specifically noted in national guidance, many areas may be reluctant to allow their use as an alternative to cloth face masks, even with sufficient modification.

In this piece, we discuss the benefits of face shields as a substitute to face masks in the context of public health policy. We further discuss the implications …

Why The Government Shouldn't Pay People To Get Vaccinated Against Covid-19, Ana Santos Rutschman

All Faculty Scholarship

As several pharmaceutical companies approach the Food and Drug Administration (FDA) seeking authorization to bring COVID-19 vaccines to market, concerns about vaccine mistrust cloud the prospects of imminent vaccination efforts across the globe. These concerns have prompted some commentators to suggest that governments may nudge vaccine uptake by paying people to get vaccinated against COVID-19. This post argues that, even if potentially viable, this idea is undesirable against the backdrop of a pandemic marked by the intertwined phenomena of health misinformation and mistrust in public health authorities. Even beyond the context of COVID-19, paying for vaccination is likely to remain …

Structural Biology Of The Enterovirus Replication-Linked 5'-Cloverleaf Rna And Associated Virus Proteins, Steven M. Pascal, Ravindranath Garimella, Meghan S. Warden, Komala Ponniah

Chemistry & Biochemistry Faculty Publications

Although enteroviruses are associated with a wide variety of diseases and conditions, their mode of replication is well conserved. Their genome is carried as a single, positive-sense RNA strand. At the 5′ end of the strand is an approximately 90-nucleotide self-complementary region called the 5′ cloverleaf, or the oriL. This noncoding region serves as a platform upon which host and virus proteins, including the 3B, 3C, and 3D virus proteins, assemble in order to initiate replication of a negative-sense RNA strand. The negative strand in turn serves as a template for synthesis of multiple positive-sense RNA strands. Building on structural …

Health Behaviors And Pandemics, Jay E. Maddock, Anna E. Greer

Public Health Faculty Publications

Human health behaviors are essential to reducing the spread and impact of pandemics. However, most behavioral scientists do not work in the area of pandemics given the infrequency of their occurrences. This editorial examines relevant health behavior theories, in particular the precaution adoption process model, and how these apply to the COVID-19 pandemic.

Benitez, Nicholas Musinguzi, David Bangsberg, Mwebesa B. Bwana, Conrad Muzoora, Peter Hunt, Jeffrey N. Martin, Jessica E. Haberer, Maya L. Petersen

OHSU-PSU School of Public Health Faculty Publications and Presentations

Introduction

Real‐time electronic adherence monitoring (EAM) systems could inform on‐going risk assessment for HIV viraemia and be used to personalize viral load testing schedules. We evaluated the potential of real‐time EAM (transferred via cellular signal) and standard EAM (downloaded via USB cable) in rural Uganda to inform individually differentiated viral load testing strategies by applying machine learning approaches.

Methods

We evaluated an observational cohort of persons living with HIV and treated with antiretroviral therapy (ART) who were monitored longitudinally with standard EAM from 2005 to 2011 and real‐time EAM from 2011 to 2015. Super learner, an ensemble machine learning method, …

Hiv Care Continuum Characteristics Among People With Opioid Use Disorder And Hiv In Vietnam: Baseline Results From The Bravo Study, Caroline King, Le Minh Giang, Gavin Bart, Lynn Elizabeth Kunkel, P. Todd Korthuis

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Little is known about patient characteristics that contribute to initiating antiretroviral therapy (ART) and achieving viral suppression among HIV people with opioid use disorder in Vietnam. The primary objective of this analysis was to evaluate associations between participant characteristics and the critical steps in the HIV care continuum of ART initiation and HIV viral suppression among people with opioid use disorder and HIV in Vietnam.

Methods

We assessed baseline participant characteristics, ART status, and HIV viral suppression (HIV RNA PCR < 200 copies/mL) enrolled in a clinical trial of HIV clinic-based buprenorphine versus referral for methadone among people with opioid use disorder in Vietnam. We developed logistic regression models to identify characteristics associated with ART status and HIV viral suppression.

Results

Among 283 study participants, 191 (67.5%) were prescribed ART at baseline, and 168 of those on ART (90%) …

Analysis Of Covid-19 Transmission: Low Risk Of Presymptomatic Spread?, Mark K. Slifka, William B. Messer, Ian J. Amanna

OHSU-PSU School of Public Health Faculty Publications and Presentations

More than 6 million confirmed cases of COVID-19 (coronavirus disease 2019) have been identified worldwide and a number of case reports1-5 have indicated that COVID-19 has the potential to be transmitted prior to disease onset. Studies have also shown that infectious virus can be isolated from presymptomatic COVID-19 cases6 and although it is unknown what level of infectious virus is needed to confer efficient transmission potential, detection of infectious virus in the upper respiratory tract indicates that presymptomatic transmission of COVID-19 is plausible. Fear of asymptomatic and presymptomatic transmission of COVID-19 has led to considerable concern among public health policy …

In a pattern repeated around the country, Oregon reported its first coronavirus patient on February 28, 2020.1 A week later, the governor declared a state of emergency.2 While the media initially focused on efforts to address COVID-19 in large cities, many rural communities were working in parallel to prepare. In these rural areas, there was an increasing concern that the burden of COVID-19 may be particularly dire due to factors such as older populations, higher prevalence of chronic diseases and poverty, and less health care access.3-6 Rural clinicians, especially those working in outpatient settings, are caring for patients during the …

Molecular Analysis Of Lymphoid Tissue From Rhesus Macaque Rhadinovirus-Infected Monkeys Identifies Alterations In Host Genes Associated With Oncogenesis, Ryan D. Estep, Aparna N. Govindan, Minsha Manoharan, He Li, Suzanne S. Fei, Byung S. Park, Michael K. Axthelm, Scott Wong

OHSU-PSU School of Public Health Faculty Publications and Presentations

Rhesus macaque (RM) rhadinovirus (RRV) is a simian gamma-2 herpesvirus closely related to human Kaposi’s sarcoma-associated herpesvirus (KSHV). RRV is associated with the development of diseases in simian immunodeficiency virus (SIV) co-infected RM that resemble KSHV-associated pathologies observed in HIV-infected humans, including B cell lymphoproliferative disorders (LPD) and lymphoma. Importantly, how de novo KSHV infection affects the expression of host genes in humans, and how these alterations in gene expression affect viral replication, latency, and disease is unknown. The utility of the RRV/RM infection model provides a novel approach to address these questions in vivo, and utilizing the RRV …
