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 …

Employee Testing, Tracing, And Disclosure As A Response To The Coronavirus Pandemic, Matthew T. Bodie, Michael Mcmahon

All Faculty Scholarship

As the COVID-19 pandemic continues to devastate the United States, the federal government has largely failed to implement a national program to prevent and contain the virus. As a result, many employers have undertaken their own workplace coronavirus mitigation efforts. This essay examines, in three parts, the legal framework surrounding employer systems of workplace testing, tracing, and disclosure. It first examines the legal issues surrounding employer-mandated COVID-19 testing and temperature checks, especially issues arising under the Americans with Disabilities Act (ADA) and Health Information Portability and Accountability Act (HIPAA). Regarding employer contact tracing efforts, the essay next reviews the multitude …

Substance Use Disorder, Discrimination, And The Cares Act: Using Disability Law To Strengthen New Protections, Kelly K. Dineen, Elizabeth Pendo

All Faculty Scholarship

The COVID-19 pandemic is having devastating consequences for people with substance use disorders (SUD). SUD is a chronic health condition—like people with other chronic health conditions, people with SUD experience periods of remission and periods of exacerbation and relapse. Unlike people with most other chronic conditions, people with SUD who experience a relapse may face criminal charges and incarceration. They are chronically disadvantaged by pervasive social stigma, discrimination, and structural inequities. People with SUD are also at higher risk for both contracting the SARS-CoV-19 virus and experiencing poorer outcomes. Meanwhile, there are early indications that pandemic conditions have led to …

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 …

'Terroristic Threats' And Covid-19: A Guide For The Perplexed, Chad Flanders, Courtney Federico, Eric Harmon, Lucas Klein

All Faculty Scholarship

The first few months of the COVID-19 outbreak in the United States saw the rise of a troubling sort of behavior: people would cough or spit on people or otherwise threaten to spread the COVID-19 virus, resulting in panic and sometimes thousands of dollars’ worth of damages to businesses. Those who have been caught doing this — or have filmed themselves doing it — have been charged under so-called “terroristic threat” statutes. But what is a terroristic threat, and is it an appropriate charge in these cases? Surprisingly little has been written about these statutes given their long history and …

Community-Acquired Pneumonia In Adults: Diagnostic Reliability Of Physical Examination Techniques And Their Teaching In Academia, Amber Tordoff, Lauren A. Williams

Physician Assistant Capstones, 2016 to 2019

Background: Chest physical examination techniques are taught in academia, but their usefulness in the evaluation and diagnosis of patients in the clinical setting is controversial. Objective: To investigate the accuracy of physical examination techniques and their reliability in diagnosing community acquired pneumonia (CAP) and suggest a modified teaching approach to be used in academia. Design: Systematic Literature Review. Methods: Database search of PubMed and Google Scholar using the search terms “prediction of pneumonia in adults” and “prediction rule for pulmonary infiltrates.” Filters were implemented to include articles that only dealt with human subjects and were full text. Articles …

Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.

A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment.

Twenty nine percent of patients were not immunosuppressed. Histoplasma antigen, or anti-Histoplasma antibodies were detected in the …

Airway Secretory Micrornaome Changes During Rhinovirus Infection In Early Childhood., M. Gutierrez, J. Gomez, Geovanny Perez, Krishna Pancham, Dinesh K. Pillai, M. Giri, S. Ferrante, Robert J. Freishtat, Mary C. Rose, Diego A. Preciado, Gustavo Nino

Pediatrics Faculty Publications

BACKGROUND:

Innate immune responses are fine-tuned by small noncoding RNA molecules termed microRNAs (miRs) that modify gene expression in response to the environment. During acute infections, miRs can be secreted in extracellular vesicles (EV) to facilitate cell-to-cell genetic communication. The purpose of this study was to characterize the baseline population of miRs secreted in EVs in the airways of young children (airway secretory microRNAome) and examine the changes during rhinovirus (RV) infection, the most common cause of asthma exacerbations and the most important early risk factor for the development of asthma beyond childhood.

METHODS:

Nasal airway secretions were obtained from …

Real-World Comparison Of Two Molecular Methods For Detection Of Respiratory Viruses, Syed Asad Ali, James E. Gern, Tina V. Hartert, Kathryn M. Edwards, Marie R. Griffin, E Kathryn Mille, Tebeb Gebretsadik, Tressa Pappas, Wai Ming Lee, John V. Williams

Department of Paediatrics and Child Health

Background: Molecular polymerase chain reaction (PCR) based assays are increasingly used to diagnose viral respiratory infections and conduct epidemiology studies. Molecular assays have generally been evaluated by comparing them to conventional direct fluorescent antibody (DFA) or viral culture techniques, with few published direct comparisons between molecular methods or between institutions. We sought to perform a real-world comparison of two molecular respiratory viral diagnostic methods between two experienced respiratory virus research laboratories.
Methods: We tested nasal and throat swab specimens obtained from 225 infants with respiratory illness for 11 common respiratory viruses using both a multiplex assay (Respiratory MultiCode-PLx Assay [RMA]) …

The Role Of The Ras Superfamily Small G-Proteins In The Proinflammatory Environment Of Rhinovirus-Exposed Monocytic-Lineage Cells, Michael Schreiber

Lawrence University Honors Projects

Rhinoviral infections are a major cause of asthma exacerbations, and though productive rhinovirus infection occurs predominantly in the bronchial epithelial cells of the upper airway, monocytic-lineage cells are implicated in establishing the inflammatory microenvironment observed during rhinoviral asthma exacerbation. It has remained unclear whether small G-protein activation plays a role in establishing this inflammatory microenvironment. The small molecular- weight G-proteins are known to be activated in a variety of cell types upon exposure to a range of viruses. However, it is unclear if small G-protein activation during viral exposure is a byproduct of receptor attachment, is important for viral replication, …
