Application Of Methods To Population-Based Surveys To Reduce Bias In Estimates Of Sars-Cov-2 Infection Burden In The Population, Saba Qasmieh

Dissertations and Theses

BACKGROUND: Population-based surveys designed to randomly sample the population can be a critical and complementary tool to traditional surveillance approaches. Probability-based surveys enable the measurement of SARS-CoV-2 testing and outcomes that avoid issues around self-selection into testing, making them an effective approach to address ascertainment bias in passive surveillance. For surveys to be a useful and reliable surveillance tool for understanding the burden and distribution of SARS-CoV-2 infection, they need to capture prevalence estimates that are both valid and reliable to be optimally informative for public health measures. The dissertation was undertaken to address three main gaps that have implications …

Strengthening U.S. Jail Systems’ Response To Infectious Diseases: An Evaluation Of The Covid-19 Pandemic, Erinn Bacchus

Dissertations and Theses

Jails across the United States were struck with increased infections and deaths during the COVID-19 pandemic. Studies have shown the structural make up of jails, lack of preparedness plans, and overcrowding contributed to health risks and poor health outcomes both inside jails and local communities. Yet little research has been dedicated to strengthening jail responses to infectious disease outbreaks spanning prevention measures, data collection, and reentry planning. Gaps include information on the (1) myriad infectious disease mitigation strategies used in jails and adherence to CDC prevention guidelines, (2) development of a standardized epidemiologic surveillance system, and (3) experiences working at …

The Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) remains a public health concern and a subject of active research effort. Development of pre-clinical animal models is critical to study viral-host interaction, tissue tropism, disease mechanisms, therapeutic approaches, and long-term sequelae of infection. Here, we report two mouse models for studying SARS-CoV-2: A knock-in mAce2F83Y,H353K mouse that expresses a mouse-human hybrid form of the angiotensin-converting enzyme 2 (ACE2) receptor under the endogenous mouse Ace2 promoter, and a Rosa26 conditional knock-in mouse carrying the human ACE2 allele (Rosa26hACE2). Although the mAce2F83Y,H353K mice were susceptible to …

Polarization, The Pandemic, And Public Trust In Health System Actors, Alessandro Del Ponte, Alan S. Gerber, Eric M. Patashnik

Political Science Faculty Articles and Research

Context: Public opinion on the performance of health system actors is polarized today, but it remains unclear which actors enjoy the most or the least trust among Democrats and Republicans, whether the COVID-19 pandemic has influenced how people view their own physicians, and whether doctors have retained the ability to influence public beliefs about policy issues.

Methods: The authors conducted two national surveys in 2022 and 2023 to examine these questions.

Findings: Democrats rated the performance of medical research scientists and public health experts during the pandemic more highly than did Republicans and independents. About three in ten Republicans said …

Covid-19 Ethics: Unique Aspects And A Review As Of Early 2024, Wayne X Shandera

Faculty, Staff and Students Publications

COVID-19 presents a variety of ethical challenges in a set of arenas, arenas not always considered in past pandemics. These challenges include issues related to autonomy, distributive ethics, and the establishment of policies of equity and justice. Methods are a literature review based on regular editing of an online textbook during the COVID-19 outbreak and a literature review using key ethical terms. Patients are confronted with new issues related to autonomy. Providers need to expand their concepts of ethical issues to include decisions based on proportionality and public health ethics. The public health sector needs to assess the beneficence of …

OBJECTIVES: Beginning early in the pandemic, there was a worldwide effort to develop effective vaccines against the SARS-CoV-2 virus. Before and after the approval and implementation of vaccines, there were concerns about their need as well as their safety and rapid development. We explored child demographic characteristics and parental concerns to identify factors associated with the decision to vaccinate.

METHODS: A cohort of 1035 children from Calgary was assembled in 2020 to participate in 5 visits every 6 months for survey completion and blood sampling for SARS-CoV-2 antibodies. Visits 1 to 2 occurred before approval of vaccines for children; Visits …

Automated Spontaneous Echo Contrast Detection Using A Multisequence Attention Convolutional Neural Network, Ouwen Huang, Zewei Shi, Naveen Garg, Corey Jensen, Mark L Palmeri

Faculty, Staff and Student Publications

OBJECTIVE: Spontaneous echo contrast (SEC) is a vascular ultrasound finding associated with increased thromboembolism risk. However, identification requires expert determination and clinician time to report. We developed a deep learning model that can automatically identify SEC. Our model can be applied retrospectively without deviating from routine clinical practice. The retrospective nature of our model means future works could scan archival data to opportunistically correlate SEC findings with documented clinical outcomes.

METHODS: We curated a data set of 801 archival acquisitions along the femoral vein from 201 patients. We used a multisequence convolutional neural network (CNN) with ResNetv2 backbone and visualized …

A Dual-Angle Exploration Towards Understanding Lapses In Covid-19 Social Responsibility, Sean T. H. Lee, Jerome J. X. Mah, Angela K. Y. Leung

Research Collection School of Social Sciences

Breaking infection chains requires not just behaviours that allow individuals to stay healthy and uninfected (i.e. health protective behaviours) but also for those who are possibly infected to protect others from their harboured infection risk (i.e. socially responsible behaviours). However, socially responsible behaviours entail costs without clear, immediate benefits to the individual, such that public health-risking lapses occur from time to time. In this important yet understudied area, the current exploratory study sought to identify possible psychological factors that may affect people's likelihood of engaging in socially responsible behaviours. Assuming that self-perceived infection should provide an impetus to engage in …

Vaccine Uptake And Intentions: Insights From A Texas Survey On Factors Influencing Covid-19 Vaccination Decisions, Yordanos M Tiruneh, Paula M Cuccaro, Kimberly S Elliott, Jing Xie, Journey Martinez, Mark Owens, Christian R Alvarado, Jose-Miguel Yamal

Faculty, Staff and Student Publications

The effectiveness of COVID-19 vaccines depends on widespread vaccine uptake. Employing a telephone-administered weighted survey with 19,502 participants, we examined the determinants of COVID-19 vaccine acceptance among adults in Texas. We used multiple regression analysis with LASSO-selected variables to identify factors associated with COVID-19 vaccine uptake and intentions to receive the vaccine among the unvaccinated. The prevalence of unvaccinated individuals (22%) was higher among those aged 18-39, males, White respondents, English speakers, uninsured individuals, those facing financial challenges, and individuals expressing no concern about contracting the illness. In a fully adjusted regression model, higher odds of being unvaccinated were observed …

Avidity Maturation Of Humoral Response Following Primary And Booster Doses Of Bnt162b2 Mrna Vaccine Among Nursing Home Residents And Healthcare Workers, Oladayo A. Oyebanji, Nicholas Sundheimer, Vaishnavi Ragavapuram, Brigid M. Wilson, Jürgen Bosch, Christopher L. King, David H. Canaday

Faculty Scholarship

Infections, despite vaccination, can be clinically consequential for frail nursing home residents (NHR). Poor vaccine-induced antibody quality may add risk for such subsequent infections and more severe disease. We assessed antibody binding avidity, as a surrogate for antibody quality, among NHR and healthcare workers (HCW). We longitudinally sampled 112 NHR and 52 HCWs who received the BNT162b2 mRNA vaccine after each dose up to the Wuhan-BA.4/5-based Omicron bivalent boosters. We quantified anti-spike, anti-receptor binding domain (RBD), and avidity levels to the ancestral Wuhan, Delta, and Omicron BA.1 & 4/5 strains. The primary vaccination series produced substantial anti-spike and RBD levels …

Asymptomatic Covid-19-Associated Acquired Hemophilia A And Disseminated Intravascular Coagulation From A Bypassing Agent, Abraham Attah, Deanna Huffman, Palash Asawa, Vinay Edlukudige Keshava, Deep Shah

School of Medicine Faculty Publications

Acquired hemophilia A (AHA) is a clotting disorder characterized by the presence of neutralizing antibodies that inhibit factor VIII, resulting in increased bleeding risk. Known etiologies include malignancy, autoimmune conditions, graft-vs-host disease, and more recently coronavirus disease 2019 (COVID-19) infection. In this case report, we describe an 86-year-old female who was found to have AHA incidentally during preoperative workup for meningioma resection. She was subsequently found to have COVID-19 infection which was the likely cause of her development of AHA. She was treated with factor eight inhibitor bypassing agent (FEIBA) and recombinant factor VII (rVII) for a small hematoma on …

Long-term immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) requires the identification of T-cell epitopes affecting host immunogenicity. In this computational study, we explored the CD8+ epitope diversity estimated in 27 of the most common HLA-A and HLA-B alleles, representing most of the United States population. Analysis of 16 SARS-CoV-2 variants [B.1, Alpha (B.1.1.7), five Delta (AY.100, AY.25, AY.3, AY.3.1, AY.44), and nine Omicron (BA.1, BA.1.1, BA.2, BA.4, BA.5, BQ.1, BQ.1.1, XBB.1, XBB.1.5)] in analyzed MHC class I alleles revealed that SARS-CoV-2 CD8+ epitope conservation was estimated at 87.6%–96.5% in spike (S), 92.5%–99.6% in membrane (M), and 94.6%–99% in …

Potential Adverse Cardiovascular Side Effects Following Mrna Covid-19 Vaccination, Abigayle Strohmeier

Senior Honors Theses

The COVID-19 vaccine, regarded as a triumph by some and a danger by others, has been studied due to the presence of adverse cardiovascular side effects experienced by some individuals following vaccination. Incidence and prevalence rates of these effects are examined by various demographic factors, primarily age and sex. The most prevalent adverse cardiovascular effects noted are myocarditis, pericarditis, cardiovascular disease, tachycardia, hypertension, palpitation, and acute myocardial infarction. Due to the novelty of the mRNA COVID-19 vaccine, many health studies have focused their data analysis on age or sex characteristics, however many excellent opportunities for future research are necessary to …

The Effect Of Covid-19 Pandemic On Sanitation Practices And Anxiety In The General Population, Leah Cliatt, Joanna Petrides

Rowan-Virtua Research Day

Background: Illness anxiety and fear of contracting coronavirus increased considerably during the COVID-19 pandemic. The media, being in lockdown, and cyberchondria had the largest impact on the population’s anxiety surrounding illness. While this kind of reaction to illness is expected during the pandemic, there is limited data on post-pandemic illness anxiety levels in the general population. Patients’ perception of disease impacts medicine at every level; medical professionals need to understand the concerns and fears of their patients in order to treat the post-pandemic patient. We hypothesized that sanitation practices and anxiety surrounding illness have not returned to baseline pre-COVID-19 …

The Impact Of The Covid-19 Mask Mandate On Effective Communication Between Healthcare Providers And Deaf/Hoh Patients, Antonia J. Conti, Alexa Gingerich

Rowan-Virtua Research Day

During the peak of the COVID-19 pandemic, many countries mandated the use of facial masks in public environments, especially in healthcare settings.[3] While this was beneficial in reducing the spread of the coronavirus disease, it created many challenges for the deaf/HoH community.[4] In particular, it limited effective communication between healthcare providers and deaf/HoH patients. It was found that masks limit word recognition for both deaf/HoH and non-deaf/HoH individuals. Additionally, both surgical and N95 masks hinder word recognition for deaf/HoH individuals and significantly impact communication during medical appointments.

Dual-Systems And Fuzzy-Trace Theory Predictions Of Covid-19 Risk Taking In Young Adults, Sarah M. Edelson, Valerie F. Reyna, Bridget B. Hayes, David M. N. Garavito

Articles

Risk-reduction behaviors are the first line of defense in viral epidemics. Choosing to not engage in risk-reduction behaviors produced millions of preventable deaths from COVID-19. Understanding why this happens and how to predict it is important for theory development and public policy. We took four approaches to this problem: experimentally varying theory-driven predictors (social rewards, transmission risk, and mandatory/voluntary regulations) in choice scenarios, further probing choices in specific scenarios predicted to elicit risk taking, conducting hierarchical regressions with demographic and theory-driven predictors for both scenario types, and conducting corresponding regressions for self-reported protective behaviors. The sample consisted of 247 young …

Betrayal As A Moderator Of Covid-19 Exposure And Ptsd Symptoms, Karly Sara Weinreb

Theses, Dissertations and Culminating Projects

In response to the COVID-19 pandemic, there has been interest in understanding how individuals have fared regarding their mental health symptoms, such as symptoms of PTSD. Prior studies have established a link between COVID-19 and PTSD without considering how COVID-19 may relate to the four PTSD symptom clusters. Further, those who feel betrayed by either an individual or institution tend to have more severe PTSD (Martin et al., 2013). It is possible that individuals felt a level of both interpersonal and institutional betrayal towards other individuals or institutions for exposing them to environments in which there was a risk of …

The Role Of Cosmopolitan Orientation In Covid-19-Related Attitudes: Perceived Threats And Opportunities, Vaccination Willingness, And Support For Collective Containment Efforts, Angela K. Y. Leung, Brandon Koh, Verity Yu Qing Lua, James H. Liu, Sarah Y. Choi, I-Ching Lee, Michelle Lee, Mei-Hua Lin, Darrin Hodgetts, Sylvia X. Chen

Research Collection School of Social Sciences

Cosmopolitan individuals identify themselves as "citizens of the world." In the present research, we tested the idea that endorsing a cosmopolitan orientation (CO) is adaptive in the COVID-19 crisis. Cosmopolitan individuals more readily transcend national parochialism, show greater concern for all humanity, and prioritize collective interests. In a two-wave multi-region investigation with six samples from China, Hong Kong, Taiwan, Malaysia, Singapore, and the U.S., we first established longitudinal and cross-cultural measurement invariance of the CO scale. Next, we found that people with a higher CO tended to perceive over time a greater threat posed by COVID-19, take more safety measures, …

COVID-19 mortality rates per 100,000 workers were calculated and compared using rate ratios for occupational …

Examining The Association Between Smoking Frequency And Long Covid: A Brfss Study, Bhavya Patel

Capstone Experience: Master of Public Health

Objectives: To examine the relationship between self-reported smoking frequency and the presence of Long COVID among individuals who tested positive for COVID-19.

Methods: A cross-sectional study was conducted using a sample of 44,738 COVID-positive participants from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) dataset. Logistic regression was utilised to compute prevalence odds ratios (pOR) and was adjusted for potential sociodemographic confounders.

Results: Individuals who smoked daily were found to have a greater likelihood of reporting Long COVID in comparison with nonsmokers (Crude pOR=1.22; CI= [1.10-1.35]). However, in the adjusted regression model, daily smoking was no longer significant (Adjusted pOR=1.04; …

A Cross-Sectional Analysis Of Self-Reported Long Covid And Binge Drinking Amongst Covid-Positive Individuals Using The Behavioral Risk Factor Surveillance System (Brfss), 2022, Maire Kirley

Capstone Experience: Master of Public Health

Objective: Identify an association between Long COVID (exposure) and binge drinking (outcome) amongst COVID-positive individuals.

Methods: COVID-positive respondents (n=116,120) were sampled from the 2022 Behavioral Risk Factor Surveillance System (BRFSS). Univariate analysis assessed distribution of Long COVID, binge drinking, and covariates sex, age, race/ethnicity, education, income, rural/urban residency, veteran status and BMI. Bivariate analysis determined crude prevalence odds ratios (POR) between exposure, outcome, and covariates. Multivariate logistic regression determined adjusted prevalence odds ratios (aPOR) and 95% confidence intervals (95% CI) for exposure, outcome and covariates.

Results: No association found between Long COVID and binge drinking (aPOR: 0.94 (95% CI: 0.87, …

Duncan NRI Faculty and Staff Publications

RNA viruses, like SARS-CoV-2, depend on their RNA-dependent RNA polymerases (RdRp) for replication, which is error-prone. Monitoring replication errors is crucial for understanding the virus’s evolution. Current methods lack the precision to detect rare de novo RNA mutations, particularly in low-input samples such as those from patients. Here, we introduce a new targeted Accurate RNA Consensus sequencing method (tARC-seq) to accurately determine the mutation frequency and types in SARS-CoV-2, both in cell culture and clinical samples. Our findings show an average of 2.68×10−5 new errors per cycle with a C>T bias that cannot be solely attributed to APOBEC …
