Using Predicted Heat Strain To Evaluate Sustainable Exposures, Samantha L. Thacker

USF Tampa Graduate Theses and Dissertations

The most commonly used exposure assessment for heat stress is based on Wet Bulb Globe Temperature (WBGT), and the limits are based on empirical relationships that demonstrate a sustainable exposure. The ISO 7933 (2017) describes Predicted Heat Strain (PHS), which is a rational model for heat stress assessment that is used to assess time-limited exposures. Investigators have examined PHS validity under a variety of time-limited conditions. The purpose of this paper is to evaluate if PHS can predict sustainable exposures.

The data used for this study were from two previous heat stress studies using a progressive heat stress protocol. The …

A Mendelian Randomization Study Of Coronary Artery Disease And Three Amino Acids: Alanine, Glycine, And Glutamine, Allan Uribe

Dissertations and Theses

Cardiovascular disease is the leading cause of death worldwide. Coronary Artery Disease (CAD) accounts for the majority of those deaths. Observational studies have identified risk factors that have been helpful in lowering the death rate, including hypertension, high cholesterol, diabetes, smoking, physical inactivity and poor diet. The effects of these risk factors on CAD remain unclear. To clarify the effect of three amino acids, alanine, glutamine, and glycine on CAD I applied a two sample Mendelian randomization analysis to extensively genotyped observational data. In a sample with up to 184,000 individuals and approximately 60,000 controls, SNPs that reached genome wide …

The Association Of Higher Carbon Dioxide Levels And Teachers’ Perceived Air Quality And Well Being In New York City Elementary Schools, Leon Levine

Dissertations and Theses

Introduction:

Several recent studies have investigated the direct effects of carbon dioxide (CO₂) at concentrations typically found in office buildings on occupant cognitive functioning. These studies have reported a significant association between (impaired) decision making ability and exposure to increased levels of CO₂ (600 ppm versus 1500 ppm). The findings have serious implications in a classroom setting since the objective of schools is to provide an optimal environment for learning. If CO₂ levels in schools are elevated, the teachers’ health and the students’ learning environment will be compromised. Higher CO₂ levels could impact teachers’ and …

Legal Remedies To Address Stigma-Based Health Inequalities In The United States: Opportunities And Challenges, Valarie K. Blake, Mark L. Hatzenbuehler

Faculty & Staff Scholarship

Stigma is an established driver of population-level health outcomes. Antidiscrimination laws can generate or alleviate stigma and, thus, are a critical component in the study of improving population health.

Currently, antidiscrimination laws are often underenforced and are sometimes conceptualized by courts and lawmakers in ways that are too narrow to fully reach all forms of stigma and all individuals who are stigmatized.

To remedy these limitations, we propose the creation of a new population-level surveillance system of antidiscrimination law and its enforcement, a central body to enforce antidiscrimination laws, as well as a collaborative research initiative to enhance the study …

Ifn-Γ: A Cytokine At The Right Time, Is In The Right Place, J. Daniel Burke, Howard A. Young

United States Public Health Resources

Interferon gamma has long been studied as a critical mediator of tumor immunity. In recent years, the complexity of cellular interactions that take place in the tumor microenvironment has become better appreciated in the context of immunotherapy. While checkpoint inhibitors have dramatically improved remission rates in cancer treatment, IFN-Γ and related effectors continue to be identified as strong predictors of treatment success. In this review, we provide an overview of the multiple immunosuppressive barriers that IFN-Γ has to overcome to eliminate tumors, and potential avenues for modulating the immune response in favor of tumor rejection.

The Use Of Geospatial Modeling And Novel Diagnostics To Detect And Map Risk Factors Of Soil-Transmitted Helminths In Feira De Santana, Brazil, Ryan Harry Avery

LSU Doctoral Dissertations

Soil-transmitted helminth (STH) infections impact billions of people worldwide. The traditional STH control approach is a morbidity control strategy implementing mass drug administration (MDA) programs targeting school-aged children (SAC). In Brazil, this control strategy has decreased STH prevalence to less than 20% in most of the country and providing an opportunity to transition from the morbidity control program and towards a surveillance and response system geared towards STH elimination. Surveillance and response systems geared towards elimination require the implementation higher accuracy diagnostics to detect infection in low-transmission communities, surveillance of entire households, high-resolution modeling at the household-habitat scale, and targeted …

Furthermore, it assists with distinguishing the types …

Computational Feasibility Of Simulating Whole-Organ Vascular Networks And Their Response To Injury, William Patrick Donahue

LSU Doctoral Dissertations

Healthy vasculature is critical to sustaining the function of normal tissues in the human body. Radiation therapy for cancer causes injury of the vasculature of non-cancerous tissues. These changes have been associated with potentially deadly conditions such as necrosis of the brain tissue. There are currently no computational methods to study the effects of radiation vascular injury in whole-organ vasculatures because of the large number of vessels involved. The goal of this work was to test the feasibility of simulating radiation damage to whole-brain vascular networks and calculate the resulting change in blood flow. To accomplish this, we developed algorithms …

Epidemiology And Ideology: Why Health Equity Is Problematic In The United States, Cynthia R. Hall

Florida Public Health Review

Health and healthcare are central elements to the achievement of social justice. Braveman and Gruskin are proponents of health equity as a means to realize social justice. They define health equity as the “absence of systemic barriers to health” that are derived from the unequal power, influence, and capital of marginalized groups within societies (2003, p. 254). John Rawls and Norman Daniels have theorized that social justice requires a fair distribution of goods in a society and that good health is of moral importance to this effort, respectively. Thus, having fair access to a healthy life is a crucial element …

La Lambda-Cyhalothrine Comme Insecticide En Milieu Agricole : Étude De La Toxicocinétique De Biomarqueurs Pour Le Suivi De L’Exposition Des Travailleurs, Michèle Bouchard, Jonathan Côté, Rania Khemiri

Rapports de recherche scientifique

Les insecticides pyréthrinoïdes sont une famille de pesticides largement utilisés au Québec pour lutter contre les insectes nuisibles dans les cultures maraîchères. Parmi ces insecticides, on compte la lambda-cyhalothrine. Malgré l’utilisation abondante de ce pyréthrinoïde, il existe peu de données sur le comportement biologique de cette molécule chez l’humain. Il devient donc essentiel de développer des outils pour bien évaluer l’exposition des travailleurs à ces pesticides lors d’épandages ou de travaux dans des zones traitées. La surveillance biologique, par la mesure de produits excrétés dans l’urine (appelés métabolites), est considérée comme une approche privilégiée pour évaluer les doses réellement absorbées …
