Insights Into Covid-19 Dynamics Via The Integration Of Subpopulations, Vaccinations, And Bayesian Calibration In A Semi-Enclosed Community Model Framework, Meghan Rowan Childs Apr 2025

Insights Into Covid-19 Dynamics Via The Integration Of Subpopulations, Vaccinations, And Bayesian Calibration In A Semi-Enclosed Community Model Framework, Meghan Rowan Childs

Theses

From the beginning of the COVID-19 pandemic, universities have experienced unique challenges due to their multifaceted nature as a place of education, residence, and employment. Previous work has used mathematical models to explore varying approaches to combating COVID-19 and tailored these models to local contexts, such as hospitals. However, previous work has not broadly incorporated pharmaceutical mitigation strategies into university models. We address this gap in research by integrating subpopulations, vaccines, and COVID-19 variants into a semi-enclosed population model framework. We further improve the quantification of uncertainty in the model parameters by implementing a formal Bayesian model calibration, fusing real-world …

Jurnal Biostatistik, Kependudukan, dan Informatika Kesehatan

Death due to SARS-CoV-2 generally occurs in patients requiring hospital care (hospitalization). However, it is still unclear whether vaccination acts as a protective factor against hospitalization in SARS-CoV-2 patients in Indonesia. This study examines the association between vaccination and hospitalization among SARS-CoV-2 patients. It employs a quantitative, cross-sectional design using secondary data from SARS-CoV-2 surveillance records at the Jakarta Health Agency (January–August 2021). Findings show that patients who received the 1st vaccine dose had a 0.34 times lower risk of hospitalization compared to unvaccinated individuals (aPOR=0.34; 95% CI=0.31–0.38). Those who received the 2nd dose had an even lower risk (aPOR=0.16; …

Transgenerational Impacts Of Covid-19: Exploring The Epigenetic Impacts Of Sars-Cov-2 Infection On Parental Reproductive Health And Offspring Development, Isaac Mckay Stirland

Theses and Dissertations

The mechanisms and consequences of SARS-CoV-2 infection, including clinical manifestations, immune response, pathogenicity, long-term sequelae, etc., have been studied in detail following the 2019 pandemic however, very little has been done to explore the interplay between SARS-CoV-2 and host DNA methylation. Given the role of DNA methylation in genetic regulation, genomic imprinting, and induction of transgenerational effects, an understanding of viral interaction(s) with the host methylome is imperative in promoting reproductive and developmental health. Numerous reports describe infections with similar pathogenicity to SARS-CoV-2 and their correlation to altered host tissues at the epigenetic, physiologic, and macroscopic level. These reported epigenetic …

Methods of censorship employed during the COVID-19 pandemic are reviewed, examples are provided, and the consequences of these actions are reviewed. Information included in this review was obtained from scientific …


Covid Cover-Up: Secrecy, Censorship And Suppression During The Pandemic, Brian Martin Mar 2025

Covid Cover-Up: Secrecy, Censorship And Suppression During The Pandemic, Brian Martin

Secrecy and Society

During the height of the COVID-19 pandemic, most health authorities, governments, and mass media organizations presented a single official view concerning lockdowns, masking, distancing, and vaccines. The methods used against contrary views can be classified into four types: flooding, ignoring, censoring, and attacking. The method of information flooding involves presenting dominant views in a unified front, overwhelming contrary views by volume and consistency. The method of ignoring includes the absence of research on alternative approaches, failure to report on research contrary to orthodoxy, and not mentioning challenging views. Censoring involves active measures to prevent the circulation of contrary information and …

BACKGROUND: Scalable identification of patients with post-acute sequelae of COVID-19 (PASC) is challenging due to a lack of reproducible precision phenotyping algorithms, which has led to suboptimal accuracy, demographic biases, and underestimation of the PASC.

METHODS: In a retrospective case-control study, we developed a precision phenotyping algorithm for identifying cohorts of patients with PASC. We used longitudinal electronic health records data from over 295,000 patients from 14 hospitals and 20 community health centers in Massachusetts. The algorithm employs an attention mechanism to simultaneously exclude sequelae that prior conditions can explain and include infection-associated chronic conditions. We performed independent chart reviews …

Overcoming Vaccine Hesitancy: Evidence From Italy During The Covid-19 Pandemic, Alessandro Del Ponte, Audrey De Dominicis, Paolo Canofari

Political Science Faculty Articles and Research

Objectives

Here we investigate whether releasing COVID-19 vaccines at open-day events boosted Italy's vaccination campaign in 2021. This strategy exploits insights from psychology.

Study design

We built an original dataset covering 200 days of vaccination data in Italy, including “open day” events. Open-day events (in short: open days) are instances where COVID-19 vaccines were released only for a specific day at a specified location (usually, a large pavilion or a public building). Importantly, releasing vaccines through open days instead of the usual appointment channel leaves the supply of vaccines unaltered. Our dependent variables are the number of total and first …

Scaling Covid-19 Rates With Population Size In The United States, Austin R. Cruz, Brian J. Enquist, Joseph R. Burger

Biology Faculty Publications

Using county-level data from the United States, we assessed allometric scaling relationships of coronavirus disease (COVID-19) cases, deaths and age structure within and across the first four major waves of the pandemic (wild-type, alpha, delta, omicron). Results generally indicate that the burden of cases disproportionately impacted larger-sized counties, while the burden of deaths disproportionately impacted smaller counties. This may be partially due to multiple interacting social mechanisms, including a higher proportion of older adults who live in smaller counties. Moreover, these likely social mechanisms interacting with vaccinations and virus waves created a dynamic pattern whereby the rate and magnitude of …


The Importance Of Public Health In College Populations: Why Vaccines Are Important, Kashish Poore Mar 2025

The Importance Of Public Health In College Populations: Why Vaccines Are Important, Kashish Poore

Honors Program: Senior Projects (Public)

This paper examines the importance of vaccines in college populations, where high-density living environments create unique vulnerabilities to infectious disease outbreaks. Despite vaccine mandates at most institutions, research indicates that many college students possess incomplete understanding of vaccine mechanisms and importance. The paper addresses three interconnected aspects: the biological foundations of vaccine-induced immunity, the significance of vaccination in collegiate settings, and the current state of vaccine literacy among students. Historical outbreaks on campuses, including meningitis at Princeton and mumps across several institutions, highlight the consequences of undervaccination. Social media misinformation has contributed significantly to vaccine hesitancy, particularly since COVID-19. The …


The Conservative Response To Transformative Disruption: Voice Or Exit 100 Years After Meyer And Pierce?, Neal Mccluskey Feb 2025

The Conservative Response To Transformative Disruption: Voice Or Exit 100 Years After Meyer And Pierce?, Neal Mccluskey

The Journal of Contemporary Legal Issues

In 1923 and 1925, respectively, the U.S. Supreme Court rulings in Meyer v. Nebraska and Pierce v. Society of Sisters established limits on the ability of government to constrain what children’s education contains and where it occurs. The Court recognized the “right” of parents to exercise basic control over those things. One hundred years later, we are seeing a renewed emphasis on “parental rights,” both with booming growth of “school choice” programs that allow government-connected funding to follow children to educational options their parents select and efforts to constrain what public schools do. The position of conservatives on such parental …

Faculty, Staff and Student Publications

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) pandemic has challenged the current understanding of the complement cascade mechanisms of host immune responses during infection-induced nonresolvable lung disease. While the complement system is involved in opsonization and phagocytosis of the invading pathogens, uncontrolled complement activation also leads to aberrant autophagic response and tissue damage. Our recent study revealed unique pathologic and fibrotic signature genes associated with epithelial bronchiolization in the lung tissues of patients with nonresolvable COVID-19 (NR-COVID-19) requiring lung transplantation. However, there is a knowledge gap if complement components are modulated to contribute to tissue …

The Impact Of Covid-19 Pandemic On The Mental Health Of Frontline Workers Of Toronto Homeless Shelters (Csws), Isiaka Omotosho Akande

Doctoral Dissertations and Projects

The objective of this phenomenological research is to understand the impact of COVID-19 on the mental health of the client service workers (CSWs) in Toronto homeless shelters. Kolcaba's theory of comfort guides this study. This theory holds that being comfortable is one of the fundamental necessities for relief after stressful health care events or incidents. Comfort boosts health-seeking behaviors for patients, clients, and workers. In the context of the City of Toronto’s homeless shelters, Kolcaba’s theory of comfort suggests that if client service workers are given adequate resources to balance their health and mental needs, thus stabilizing their comfortabilities, then …

Background: Lymphopenia and failure of lymphocytes to mount an early IFN-γ response correlate with increased mortality in COVID-19. Given the essential role of CD4 helper and CD8 cytotoxic cells in eliminating viral pathogens, this profound loss in lymphocytes may impair patients' ability to eliminate the virus. IL-7 is a pleiotropic cytokine that is obligatory for lymphocyte survival and optimal function.

Methods: We conducted a prospective, double-blind, randomized, placebo-controlled trial of CYT107, recombinant human IL-7, in 109 critically ill, patients with lymphopenia who have COVID-19.

BACKGROUND: Lymphopenia and failure of lymphocytes to mount an early IFN-γ response correlate with increased mortality in COVID-19. Given the essential role of CD4 helper and CD8 cytotoxic cells in eliminating viral pathogens, this profound loss in lymphocytes may impair patients' ability to eliminate the virus. IL-7 is a pleiotropic cytokine that is obligatory for lymphocyte survival and optimal function.

METHODS: We conducted a prospective, double-blind, randomized, placebo-controlled trial of CYT107, recombinant human IL-7, in 109 critically ill, patients with lymphopenia who have COVID-19. The primary endpoint was to assess CYT107's effect on lymphocyte recovery with secondary clinical endpoints including …

Introduction: Pregnant women are considered a high-risk group for COVID-19 infection/pneumonia as they are known to be more vulnerable to viral infections. They require close monitoring and appropriate timely intervention to minimize the impact on both the mother and the fetus. Although the more prevalent Omicron variant led to fewer severe infections and fewer intensive care unit (ICU) admissions globally during the third wave, the effect on pregnant women and pregnancy outcomes was unknown. The vaccination campaign was thoroughly established by the third wave of the pandemic in Qatar. This retrospective descriptive cohort study investigates the characteristics, hospital stay, interventions, …

Introduction

The COVID-19 pandemic highlighted the gaps and the need to strengthen the emergency care system in Uganda. The Ugandan Ministry of Health implemented an emergency care capacity-building program during the COVID-19 pandemic response to improve COVID-19 case management in Uganda. We describe the curriculum development and rollout using a cascade model.

Methods

In June 2021, the World Health Organisation (WHO) Hospital Emergency Unit Assessment Tool (HEAT) was used to assess emergency units and document existing capacity gaps in regional referral hospitals and general hospitals. The WHO Basic Emergency Care curriculum was modified to a training curriculum for emergency care …
