The Impact Of Maternal Environmental Exposures On The Immune Landscape Of The Maternal-Fetal Interface, Heather E. True Jan 2025

The Impact Of Maternal Environmental Exposures On The Immune Landscape Of The Maternal-Fetal Interface, Heather E. True

Theses and Dissertations--Pharmacy

Maternal environmental exposures and inflammation are known to impact fetal development in utero as well as increase the risk for chronic diseases later in life. Therefore, it is essential that we understand how the maternal environment alters placental structure and immune function.

Therefore, we isolated fetal (chorionic villous) tissues from the placentas of healthy pregnant participants (control) and those with inflammatory conditions, including SARS-COV-2 infection, pregravid obesity, and opioid use disorder. Isolated placental leukocytes were subjected to a series of assays to uncover the phenotypic, functional, and transcriptional (single-cell RNA-sequencing) landscape of placental immune cells. Additional placental tissues were subjected …


Simplified Molecular Diagnostics Methods For Environmental Testing Of Pathogens And Other Applications, Mohammad Dehghan Banadaki Jan 2025

Simplified Molecular Diagnostics Methods For Environmental Testing Of Pathogens And Other Applications, Mohammad Dehghan Banadaki

Theses and Dissertations--Mechanical and Aerospace Engineering

Environmental Surveillance (ES) has emerged as a powerful tool to monitor the emergence and persistence of a pathogen within a facility or community using wastewater/water analysis. Over the past four years, implementation of ES has experienced an explosive acceleration, driven by efforts to monitor the spread of SARS-CoV-2, which has made ES a routinely used public health tool in many locations. We can now use ES to measure the emergence/presence/abundance of different viruses (e.g., SARS-CoV-2, influenza, mpox), bacteria (e.g., E. coli, V. cholerae, antibiotic-resistant strains), fungi (e.g., C. auris), and other biological markers indicative of infectious diseases. However, its broad …


The Effect Of Sars-Cov-2 On Bacterial Diversity And Abundance In Community Wastewater, Joshua Lambert Jan 2025

The Effect Of Sars-Cov-2 On Bacterial Diversity And Abundance In Community Wastewater, Joshua Lambert

Graduate Theses, Dissertations, and Problem Reports (ETD)

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) enters human respiratory cells through binding of its spike (S) protein to the ACE-2 receptor, which is highly expressed in lung cells, but is also found in over 150 other cell types encompassing major organs including GI enterocytes. SARS-CoV-2 causes gut dysbiosis in infected individuals and patients with COVID-19 and also coincides with lower alpha diversity of the individual’s gut microbiome. Certain gut microbiome-associated genera are lower in abundance in COVID-19 patients including Lachnospira, Prevetolla, Roseburia, Bifidobacterium, and Faecalibacterium while genera such as Bacteroides, Enterococcus and Proteobacteria are increased during a SARS-CoV-2 …

Minds, Made Up Or Malleable? Covert Commands At The Eclipse Of Vaccine Communications, David H. Lee Jan 2025

Minds, Made Up Or Malleable? Covert Commands At The Eclipse Of Vaccine Communications, David H. Lee

Publications and Research

Abstract: Although millions have died from SARS-CoV-2 illness, COVID vaccines are credited with stemming the tide. Vaccinations and boosters significantly decrease the incidence of severe illness and death (even if they don’t usually prevent COVID-19 infection). Despite the success of global vaccination efforts, frequent reports of vaccine hesitance and refusal suggest that public health communications need improvement.

The chapter begins by acknowledging adverse events associated with COVID vaccination, including rare cases of anaphylaxis, GBS, and myocarditis. An inoculation-theoretic rationale is offered for this admission of vaccine risks: just as immune defenses mount when organisms are exposed to pathogens, so too …

Rbd Amplicon Sequencing And Evolutionary Analysis Of Sars-Cov-2 Variants From Wastewater Samples, Xingwen Chen, Chunfu Zheng, Fuqing Wu

Faculty, Staff and Student Publications

The surveillance of SARS-CoV-2 is significantly limited by the presence of numerous variants with distinct behaviors driven by rapid evolution. Although the conventional clinical genome sequencing method provides comprehensive data, it has limitations in capturing the epidemiological dynamics of the variants circulating in the community. In this chapter, we describe a protocol using RBD amplicon sequencing of wastewater samples. We present the detailed experimental procedure for wastewater sample processing, robust nested-PCR-based amplification of the target RBD sequence, and library preparation. Moreover, we describe a general pipeline of sequencing data processing and interpretation, showing the epidemiological and evolutionary trends of SARS-CoV-2 …

Problem: COVID-19 during pregnancy is linked to increased maternal morbidity and a higher incidence of preterm births (PTBs), yet the underlying mechanisms remain unclear. Cellular senescence, characterized by the irreversible cessation of cell division, is a critical process in placental function, and its dysregulation has been implicated in pregnancy complications like PTB. Senescence can be induced by various stressors, including oxidative stress, DNA damage, and viral infections.

Method of study: In this study, we determined whether COVID-19 had an impact on placental senescence. We examined placentas from women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n = 10 …

Interactions Of The Sars-Cov-2 Viral Genome 3’-Untranslated Region With Viral And Host Rnas, Caleb Frye, Mihaela Rita Mihailescu

Electronic Theses and Dissertations

This dissertation focuses on the characterization of RNA-RNA interactions within the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome and with host microRNAs. As the causative agent of coronavirus disease 2019 (COVID-19), SARS-CoV-2 has evolved rapidly since its appearance. This has warranted prompt characterization of the virus particularly of its single stranded RNA (ssRNA) genome. By using a combination of bioinformatics, biophysics, and/or biological assays, we analyzed the SARS-CoV-2 viral genomic RNA and uncovered interactions of genomic RNA with host RNAs, highlighting an underutilized method of targeting RNA viruses. We showed here that the conserved elements in the viral genomic …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: From medication usage to the time of day, a number of external factors are known to alter human body temperature (BT), even in the absence of underlying pathology. In select cases, clinical guidance already suggests the consideration of clinical and demographic factors when interpreting BT, such as a decreased threshold for fever as age increases. Recent work has indicated factors impacting BT extend to environmental conditions including ambient temperature. However, the effect sizes of these relationships are often small, and it remains unclear if such relationships result in a meaningful impact on real-world health care practices.

OBJECTIVE: Temperature remains …

Heterozygous Btnl8 Variants In Individuals With Multisystem Inflammatory Syndrome In Children (Mis-C), Evangelos Bellos, Erica G Schmitt, Et Al.

2020-Current year OA Pubs

Multisystem inflammatory syndrome in children (MIS-C) is a rare condition following SARS-CoV-2 infection associated with intestinal manifestations. Genetic predisposition, including inborn errors of the OAS-RNAseL pathway, has been reported. We sequenced 154 MIS-C patients and utilized a novel statistical framework of gene burden analysis, "burdenMC," which identified an enrichment for rare predicted-deleterious variants in BTNL8 (OR = 4.2, 95% CI: 3.5-5.3, P < 10-6). BTNL8 encodes an intestinal epithelial regulator of Vγ4+γδ T cells implicated in regulating gut homeostasis. Enrichment was exclusive to MIS-C, being absent in patients with COVID-19 or bacterial disease. Using an available functional test for BTNL8, rare variants from a larger cohort of MIS-C patients (n = 835) were tested which identified eight variants in 18 patients (2.2%) with impaired engagement of Vγ4+γδ T cells. Most of these variants were in the B30.2 domain of BTNL8 implicated in sensing epithelial cell status. These findings were associated with altered intestinal permeability, suggesting a possible link between disrupted gut homeostasis and MIS-C-associated enteropathy triggered by SARS-CoV-2.

The incidence of Kawasaki Disease has a peak in the winter months with a trough in late summer/early fall. Environmental/exposure factors have been associated with a time-varying incidence. These factors were altered during the COVID-19 pandemic. The study was performed through the International Kawasaki Disease Registry. Data from patients diagnosed with acute Kawasaki Disease and Multiple Inflammatory Syndrome-Children were obtained. Guideline case definitions were used to confirm site diagnosis. Enrollment was from 1/2020 to 7/2023. The number of patients was plotted over time. The patients/month were tabulated for the anticipated peak Kawasaki Disease season (December-April) and non-peak season (May-November). Data …

BACKGROUND: Assessments of COVID-19 vaccine effectiveness are needed to monitor the protection provided by updated vaccines against severe COVID-19. We evaluated the effectiveness of original monovalent and bivalent (ancestral strain and Omicron BA.4/5) COVID-19 vaccination against COVID-19-associated hospitalization and severe in-hospital outcomes.

METHODS: During September 8, 2022 to August 31, 2023, adults aged ≥ 18 years hospitalized with COVID-19-like illness were enrolled at 26 hospitals in 20 US states. Using a test-negative case-control design, we estimated vaccine effectiveness (VE) with multivariable logistic regression adjusted for age, sex, race/ethnicity, admission date, and geographic region.

RESULTS: Among 7028 patients, 2924 (41.6%) were …

Objectives: Rapid evolution of SARS-CoV-2 has resulted in the emergence of numerous variants, posing significant challenges to public health surveillance. Clinical genome sequencing, while valuable, has limitations in capturing the full epidemiological dynamics of circulating variants in the general population. This study aimed to monitor the SARS-CoV-2 variant community dynamics and evolution using receptor-binding domain (RBD) amplicon sequencing of wastewater samples.

Methods: We sequenced wastewater from El Paso, Texas, over 17 months, compared the sequencing data with clinical genome data, and performed biodiversity analysis to reveal SARS-CoV-2 variant dynamics and evolution.

Results: We identified 91 variants and observed waves of …

Research regarding HIV, substance use disorders (SUD), and SARS-CoV-2 infections after COVID-19 vaccination is limited. In the Veterans Aging Cohort Study (VACS)-HIV cohort, we followed vaccinated persons with HIV (PWH) and without HIV (PWoH) from 12/2020 to 3/2022 and linked SARS-CoV-2 test results for laboratory-confirmed breakthrough infection through 9/2022. We examined associations of substance use (alcohol use disorder [AUD], other SUD, smoking status) and HIV status and severity with breakthrough infections, using Cox proportional hazards regression hazard ratios (HR). To test for potential interactions between substance use and HIV, we fit survival models with a multiplicative interaction term. Among 24,253 …
