The Role Of E-Liquid Constituents In E-Cigarette-Induced Cardiac Arrhythmia And Autonomic Imbalance., Cory Kucera

Electronic Theses and Dissertations

Introduction. Accumulating evidence indicates that exposure to electronic cigarettes (e-cigs) promotes sympathetic dominance and electrophysiologic instability in the heart, potentially culminating in arrhythmogenesis. E-liquids contain various formulations of nicotine and flavorings, but the effects of specific e-liquid constituents and their concentrations on e-cig-induced autonomic imbalance and electrical dysfunction are unresolved. To that end, we tested the hypothesis that e-cigs modify cardiac autonomic balance and ventricular arrhythmogenesis in mice dependent on e-liquid constituent type and concentration. Methods. Using a crossover design and a serial exposure regimen, ECG-telemetered male C57BL/6J mice underwent whole-body exposure to e-cig aerosols generated from e-liquids containing different …

Wastewater-Informed Public Health Intervention Playbook

Sustain Magazine

As the SARS-CoV-2 pandemic quickly spread from country to country and continent to continent in 2020, governments and scientists needed a way to track COVID-19 through populations in order to position public health interventions in the most impactful locations. Having a decision-based risk framework may help to guide policy creation that could minimize or prevent possible outbreaks and surges of infection within communities. The University of Louisville in partnership with Louisville’s Department of Public Health and Wellness tested this strategy in 2021 and 2022. This Wastewater-Informed Public Health Intervention Playbook describes the decisions and actions of that academic and public …

Implementation Of A Drive-Through Covid-19 Mass Vaccination Site: Experiences From Louvax–Broadbent In Louisville, Kentucky, Ruth Carrico, Sarah Beth Hartlage, Valenchia Brown Msn, Aprn, Fnp-C, Sarah M. Bishop, Luanne Didelot, William Hayden, Beverly Williams Coleman, Sarah Tan, Delanor Manson, Kellie Kane, Dawn Balcom, Paul Kern

The University of Louisville Journal of Respiratory Infections

Background: Response to the COVID-19 pandemic has required innovative approaches to vaccination, including methods to rapidly and safely immunize communities. A major challenge to such a response involved access to untapped healthcare worker resources. The Louisville, Kentucky, response involved the use of a large volunteer workforce to supplement local public health employees in planning and implementing a large-scale drive-through vaccination event. The objective of this manuscript was to outline processes involved in training a mass immunization workforce and implementating a large-scale COVID-19 community vaccination.

Approach: Competency-based and standardized training was provided for every volunteer before working their shift. Volunteers worked …

Identifying The Cardiovascular Effects Of Multiple Pollutants., Katlyn Elizabeth Mcgraw

Electronic Theses and Dissertations

Cardiovascular disease (CVD) is the leading cause of death from environmental exposures. Although exposure to PM_2.5 is an established risk factor for CVD, the contribution of other hazardous pollutant exposure to CVD is less clear. Overall, this work aimed to examine the effect of pollutants with lesser documented effects on cardiovascular disease using a multi-pronged approach to exposure assessment. The three aims were to examine the relationship between county-level toxic chemical releases and CVD mortality in the contiguous United States between 2002 and 2012, to assess the relationship between individual-level VOC metabolites and vascular function, and to build multipollutant …

Tobacco Product-Derived Aldehydes: Effects On Circulating Angiogenic Cells & Implications For Cardiovascular Disease., Jordan B. Lynch

Electronic Theses and Dissertations

Cardiovascular disease (CVD) is the leading cause of death worldwide. Tobacco smoke is the most significant modifiable risk factor in CVD development and contains numerous toxic compounds, including aldehydes, which have been linked to CVD. Formaldehyde, acetaldehyde, acrolein, and crotonaldehyde have been identified as significant contributors to cigarette-induced health effects, but the mechanism of these effects is not well understood. These aldehydes are also found in aerosols produced by e-cigarettes (e-cigs). The goal of this dissertation was to explore the systemic, hematological, and endothelium-related effects of exposure to tobacco products and constituent aldehydes and to identify potential mechanisms of injury. …

Volatile Organic Compound Exposure And Cardiometabolic Syndrome Risk In A Nationally Representative Cohort., Stacey Lane Konkle

Electronic Theses and Dissertations

BACKGROUND: The relative importance of environmental exposures such as volatile organic compounds (VOCs) is one of the paramount public health priorities of our time, yet is presently unstudied. VOCs are ubiquitous in the environment and have been associated with numerous adverse health effects, including a number of cardiovascular and metabolic effects that are components of Cardiometabolic Syndrome (CMS). OBJECTIVES: To examine the relationship between CMS and individual-level exposures to VOCs, measured as urinary metabolites of VOCs (UM-VOCs), in a nationally representative sample. METHODS: Associations between urinary biomarkers of exposure to 19 parent VOCs and CMS were assessed using the National …
