Exploring The Possible Phenomenon Of Viral Interference Between The Novel Coronavirus And Common Respiratory Viruses, Spencer Deleveaux, Alexandria Clarke-Kregor, Xavier Fonseca-Fuentes, Essam Mekhaiel

Journal of Patient-Centered Research and Reviews

At the peak of the 2021 wave of the SARS-CoV-2 alpha variant in North America, there was concern for a superimposed wave of viral respiratory infections. There was, however, an apparent shift in the usual epidemiology of these pathogens, especially during the traditional influenza season from approximately October 2020 to March 2021. This article seeks to briefly describe the epidemiology of notable respiratory pathogens during the first wave of the COVID-19 pandemic and to focus on one possible factor for the trends observed. There are many contributory elements to the observed viral trends, but in particular, we present a synopsis …

Performance Of A Sars-Cov-2 Rt-Pcr Assay With Non-Traditional Specimen Types, Subathra Marimuthu, Holly Aliesky, Heather Ness, Daniya Sheikh, Sathya Rashmit, Dawn Balcom, Leslie A. Wolf

The University of Louisville Journal of Respiratory Infections

During the first two years of the coronavirus disease 2019 (COVID-19) pandemic, nasopharyngeal (NP) specimens were the gold standard for clinical diagnostic testing. As information about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the pandemic continued to be shared, it was clear that the virus could be detected in other specimen types during an active infection. The University of Louisville Infectious Diseases Laboratory accepted non-traditional specimen types, most without a paired, positive NP result, for research purposes only to support local epidemiology efforts. A real-time reverse transcription-polymerase chain reaction (RT-PCR) assay originally validated for NP specimens was used …

The severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19, possesses an unusually large positive-sense, single-stranded viral RNA (ssvRNA) genome of about ~29,903 nucleotides (nt). In many respects, this ssvRNA resembles a very large, polycistronic messenger RNA (mRNA) possessing a 5′-methyl cap (m7GpppN), a 3′- and 5′-untranslated region (3′-UTR, 5′-UTR), and a poly-adenylated (poly-A+) tail. As such, the SARS-CoV-2 ssvRNA is susceptible to targeting by small non-coding RNA (sncRNA) and/or microRNA (miRNA), as well as neutralization and/or inhibition of its infectivity via the human body’s natural complement of about ~2650 miRNA species. Depending on host cell and tissue …


Implementation Of Mrsa Nasal Swabs As An Antimicrobial Stewardship Intervention To Decrease Anti-Mrsa Therapy In Covid-19 Infection, Alaina Dekerlegand, Emily Johnston, Britney Mellor, Melanie Rae Schrack, Catherine O’Neal Jan 2023

Implementation Of Mrsa Nasal Swabs As An Antimicrobial Stewardship Intervention To Decrease Anti-Mrsa Therapy In Covid-19 Infection, Alaina Dekerlegand, Emily Johnston, Britney Mellor, Melanie Rae Schrack, Catherine O’Neal

School of Medicine Faculty Publications

In the early stages of treating patients with SARS-CoV-2, limited information was available to guide antimicrobial stewardship interventions. The COVID-19 Task Force and Antimicrobial Stewardship Committee, at a 988-bed academic medical center, implemented the use of methicillin-resistant Staphylococcus aureus (MRSA) nasal swab polymerase chain reaction (PCR) testing to assist with the de-escalation of anti-MRSA therapy in patients with suspected superimposed bacterial pneumonia in COVID-19. A retrospective study was conducted to evaluate the impact of MRSA nasal swab PCR testing on the rate of anti-MRSA therapy between 13 April 2020 and 26 July 2020. A total of 122 patients were included …


Investigating Stigma During The Early Stages Of A Pandemic Through The Lens Of Covid-19, Zach Thornton, Bethany Hodge, Sheridan Langford Jan 2023

Investigating Stigma During The Early Stages Of A Pandemic Through The Lens Of Covid-19, Zach Thornton, Bethany Hodge, Sheridan Langford

The University of Louisville Journal of Respiratory Infections

Background: Individuals face stigma associated with numerous health conditions. Stigma can arise rapidly during the early spread of a new disease, adding to the burden felt by those affected. COVID-19 can be used as an example to study stigma during the early phases of a pandemic. This narrative review is a descriptive analysis that tracks the ways in which COVID-19 stigma was discussed in the scholarly literature during the first year of the pandemic to understand how stigma was viewed in the context of a rapidly spreading pandemic.

Methods: PubMed was used as a non-exhaustive sample of the literature. Searches …

Medical College Documents

Multisystem Inflammatory Syndrome in Children (MIS-C), representing a new entity in the spectrum of manifestations of COVID-19, bears symptomatic resemblance with Kawasaki Disease (KD). This review explores the possible associations between KD and the human coronaviruses and discusses the pathophysiological similarities between KD and MIS-C and proposes implications for the pathogenesis of MIS-C in COVID-19. Since 2005, when a case-control study demonstrated the association of a strain of human coronavirus with KD, several studies have provided evidence regarding the association of different strains of the human coronaviruses with KD. Thus, the emergence of the KD-like disease MIS-C in COVID-19 may …

Section of Pulmonary & Critical Care

The COVID-19 pandemic has led to mortality and morbidity since December 2019. Many possible treatment options have been advised till date. The role of ivermectin in the treatment of COVID-19 disease remains controversial. The aim of our study was to evaluate the effect of ivermectin in hospitalized patients with non-severe and severe COVID-19 disease. We conducted a retrospective cohort study that compared outcomes in 2 groups of COVID-19 patients hospitalized at the largest tertiary care center of Pakistan. The study group was given ivermectin along with standard treatment of covid-19 disease; the comparison group was not. Data on mortality, inflammatory …

Introduction: Current literature indicates that African American individuals are at increased risk of becoming infected with the SARS-CoV-2 virus and suffer higher SARS-CoV-2-related mortality rates. However, there is a lack of consensus as to how the clinical outcomes of African American patients differ from those of other groups. The objective of this study was to define the clinical outcomes of African American and White hospitalized patients with SARS-CoV-2 community-acquired pneumonia (CAP) in Louisville, Kentucky.

Methods: This was a retrospective cohort study of hospitalized patients with SARS-CoV-2 CAP at eight hospitals in Louisville, Kentucky. Severity of CAP at time of hospitalization …

Background: During the ongoing pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), SARS-CoV-2 community-acquired pneumonia (CAP) has been the primary cause of hospitalization. The objective of this study was to evaluate the clinical characteristics and outcomes of 1,013 patients hospitalized with SARS-CoV-2 CAP from September 2020 through March 2021 in Louisville, Kentucky.

Methods: This was a retrospective observational study of 1,013 patients hospitalized with SARS-CoV-2 CAP at eight of the adult hospitals in the city of Louisville from September 2020 through March 2021. Patients with 1) a positive reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV-2, 2) fever, cough, or …
