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.

Developing A Virus-Like Particle (Vlp)-Based Vaccine For Neisseria Gonorrhoeae, Ashvini Vaidya

Biomedical Sciences ETDs

Neisseria gonorrhoeae (Ng) is a sexually transmitted bacterium that infects human reproductive mucosal surfaces. Due to the risk of complications in untreated cases and evolving antibiotic resistance, a prophylactic vaccine is critical for preventing infection. There are four Ng outer-membrane proteins that contribute to Ng survival and resistance: PorB, BamA, TbpA, and MtrE. Each protein contains surface-exposed loops that are targets of bactericidal antibodies. Vaccines were developed by displaying Ng epitopes on the surface of bacteriophage virus-like particles (VLP). VLPs are immunogenic, multivalent, self-assembling complexes composed of viral structural proteins. Antigenic peptide sequences can be displayed on the surface …

Rna-Gps Predicts Sars-Cov-2 Rna Residency To Host Mitochondria And Nucleolus, Kevin E Wu, Furqan M Fazal, Kevin R Parker, James Zou, Howard Y Chang

Faculty, Staff and Students Publications

SARS-CoV-2 genomic and subgenomic RNA (sgRNA) transcripts hijack the host cell's machinery. Subcellular localization of its viral RNA could, thus, play important roles in viral replication and host antiviral immune response. We perform computational modeling of SARS-CoV-2 viral RNA subcellular residency across eight subcellular neighborhoods. We compare hundreds of SARS-CoV-2 genomes with the human transcriptome and other coronaviruses. We predict the SARS-CoV-2 RNA genome and sgRNAs to be enriched toward the host mitochondrial matrix and nucleolus, and that the 5' and 3' viral untranslated regions contain the strongest, most distinct localization signals. We interpret the mitochondrial residency signal as an …

Association Of Neighborhood Disorder And Minority Stress With Depression Among Young Gay And Bisexual Males In Denver And Chicago, Liesl Gonzales, Douglas Bruce

DePaul Discoveries

Excess risk for poor mental health outcomes has been found within sexual minority populations. This study aimed to examine factors that may contribute to depression rates within two populations of YMSM in Denver and Chicago. 100 HIV-positive and 100 HIV-negative YMSM completed a survey regarding demographic information, minority stress (such as same-sex stigma), and perceived neighborhood disorder. Chicago participants reported higher rates of neighborhood disorder, history of incarceration, and being kicked out of a parent’s house, variables predicted to be positively correlated with depression. Surprisingly, it was found that YMSM in Denver were significantly more likely to have depressive symptoms …

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 …

Factors In The Probability Of Covid-19 Transmission In University Classrooms, Charles Connor

Numeracy

University students and faculty members need an effective strategy to evaluate and reduce the probability that an individual will become infected with COVID-19 as a result of classroom interactions. Models are developed here that consider the probability an individual will become infected as a function of: prevalence of the disease in the university community, number of students in class, number of class meetings, and transmission rate in the classroom given the presence of an infected individual. Absolute probabilities that an individual will become infected in a classroom environment cannot be calculated because some of these factors have unknown values. Nevertheless, …

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.

Covid-19, Single-Sourced Diagnostic Tests, And Innovation Policy, Deb Chaarushena, Osman Moneer, Nicholson W. Price Ii

Articles

At the heart of the United States, disastrous response to the Covid-19 pandemic is a failure of diagnostic testing. That something so fundamental to medical care could be so botched evokes incredulity. From primary care offices to critical care settings, every patient encounter begins with a diagnostic workup. Diagnostic testing tools are key parts of the physician’s toolkit, and confirmatory testing is essential. But in the greatest public health challenge of the 21st century, the failures of diagnostic testing have been laid entirely bare.

Immune Function During Pregnancy Varies Between Ecologically Distinct Populations, Carmen Hové, Benjamin C. Trumble, Amy S. Anderson, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven, Aaron Blackwell

ESI Publications

Background and objectives

Among placental mammals, females undergo immunological shifts during pregnancy to accommodate the fetus (i.e. fetal tolerance). Fetal tolerance has primarily been characterized within post-industrial populations experiencing evolutionarily novel conditions (e.g. reduced pathogen exposure), which may shape maternal response to fetal antigens. This study investigates how ecological conditions affect maternal immune status during pregnancy by comparing the direction and magnitude of immunological changes associated with each trimester among the Tsimane (a subsistence population subjected to high pathogen load) and women in the USA.

Methodology

Data from the Tsimane Health and Life History Project (N = 935) and …

Can Children Catch Up From The Consequences Of Undernourishment? Evidence From Child Linear Growth, Developmental Epigenetics, And Brain And Neurocognitive Development, Jef L. Leroy, Edward A. Frongillo Jr., Pragya Dewan, Maureen M. Black, Robert A. Waterland

Faculty Publications

Recovery from nutritionally induced height deficits continues to garner attention. The current literature on catch-up growth, however, has 2 important limitations: wide-ranging definitions of catch-up growth are used, and it remains unclear whether children can recover from the broader consequences of undernutrition. We addressed these shortcomings by reviewing the literature on the criteria for catch-up in linear growth and on the potential to recover from undernutrition early in life in 3 domains: linear growth, developmental epigenetics, and child brain and neurocognitive development. Four criteria must be met to demonstrate catch-up growth in height: after a period in which a growth-inhibiting …
