Prospects For Rnai Therapy Of Covid-19, Hasan Uludağ, Kylie Parent, Hamidreza Montazeri Aliabadi, Azita Haddadi

Pharmacy Faculty Articles and Research

COVID-19 caused by the SARS-CoV-2 virus is a fast emerging disease with deadly consequences. The pulmonary system and lungs in particular are most prone to damage caused by the SARS-CoV-2 infection, which leaves a destructive footprint in the lung tissue, making it incapable of conducting its respiratory functions and resulting in severe acute respiratory disease and loss of life. There were no drug treatments or vaccines approved for SARS-CoV-2 at the onset of pandemic, necessitating an urgent need to develop effective therapeutics. To this end, the innate RNA interference (RNAi) mechanism can be employed to develop front line therapies against …

Sars-Cov-2 Viral And Serological Testing When College Campuses Reopen: Some Practical Considerations, Isaac Chun-Hai Fung, Chi-Ngai Cheung, Andreas Handel

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

The coronavirus disease 2019 (COVID-19) pandemic prompted universities across the United States to close campuses in Spring 2020. Universities are deliberating whether, when, and how they should resume in-person instruction in Fall 2020. In this essay, we discuss some practical considerations for the use of 2 potentially useful control strategies based on testing: (1) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) testing followed by case-patient isolation and quarantine of close contacts, and (2) serological testing followed by an “immune shield” approach, that is, low social distancing requirements for seropositive persons. The isolation of case-patients and …

The Importance Of Cycle Threshold Values In The Evaluation Of Patients With Persistent Positive Pcr For Sars-Cov-2: Case Study And Brief Review, Jose Bordon, Donghoon Chung, Priya Krishnan, Ruth Carrico, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

Some patients recover from COVID-19, but their reverse transcription-polymerase chain reaction (RT-PCR) for SARS-CoV-2 remains persistently positive. In the evaluation of these patients, it is important to define the cycle threshold (Ct) value of the RT-PCR test. This article will present a case study, address relevant findings and interpretation of the RT-PCR test, and explain the use of Ct values in defining when a healthcare worker may return to work. Our current approach is to allow health care workers with persistently positive RT-PCR to return to work if the Ct value is greater than 35.

Covid-19 Surveillance Testing Of Healthcare Personnel Drives Universal Masking Practice, Paul S. Schulz, Ashley M. Wilde, Steve T. Hester, Jim Frazier, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

Health care professionals (HCP) are at increased risk of COVID-19 infection due to the unpredictable clinical presentation of COVID-19 disease, limited SARS-CoV-2 testing, personal protective equipment (PPE) shortages, and the inherent inability to distance from patients. Infected HCP may infect others, including coworkers, leading to a simultaneous increase in the number of infections and decrease in the availability of HCP in a community. Due to PPE shortages, many healthcare systems have faced difficult decisions regarding utilization of PPE to protect HCP, patients, and the communities they serve. We describe Norton Healthcare’s success utilizing surveillance COVID-19 testing of HCP to inform …

Why Every Hospital Needs A Covid-19 Clinical Case Review Team, Ashley M. Wilde, Paul Schulz, Brian C. Bohn, Sarah E. Moore, Matthew Song, Clayton J. Patross, Bryan Denham, Jim Frazier, Steve T. Hester, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

A hospital’s response to a global pandemic requires a coordinated effort to provide consistent guidance as information rapidly changes. In the early months of the COVID-19 pandemic, diagnosis and subsequent containment was challenging due to unfamiliarity with disease presentation, unknown reverse transcription-polymerase chain reaction sensitivity, and inconsistent access to testing supplies. A centralized COVID-19 clinical case review team can provide guidance on test interpretation, isolation, resource coordination and more.

Comparative Whole-Genome And Phenotype Analyses Of Virulence Factors And Lethality In Nematode Challenge Assay Among Aeromonas Isolates, Pyeongsug Kim

Master of Science in Integrative Biology Theses

Aeromonads are bacteria found globally in fresh and brackish waters, with some species causing water-borne diseases vertebrate hosts such as diarrhea and wound-infections in humans and motile Aeromonas septicemia in fish. Although many virulence factors have been described, determining which factors are most important in pathogenesis is ongoing. To examine this further, the genomes of five Aeromonas strains isolated from various animals were sequenced and annotated in this study. Each isolate was further characterized using comparative genomic analyses and testing for production of selected virulence factors. Although previously identified as Aeromonas hydrophila, modern genotypic approaches including multilocus sequence typing …

A Study Of Covid-19 Mortality Under Varying Patient Frailty, Alison N. Sifuentes

Theses and Dissertations

Modeled the spread and mortality of COVID-19 throughout the city of Chicago. By incorporating group frailty into a classic SEIR infectious disease model, we were able to differentiate the population of Chicago by their response to COVID-19. Three age groups with different COVID-19-induced death rates were examined, and the model sought to showcase the multiplicative deviation of each age group death rate from the average disease-induced death rate. This adjustment for different death rates among age groups accounted for heterogeneity within the population, and sought to introduce a more accurate manner for modeling the spread of infectious diseases.
