Faculty Scholarship

Background: Epidemiological nowcasting traditionally relies on count surveillance data. The availability and quality of such count data may vary over time, limiting representation of true infections. Wastewater data correlates with traditional surveillance data and may provide additional value for nowcasting disease trends. Methods: We obtained SARS-CoV-2 case, death, wastewater, and serosurvey data for Jefferson County, Kentucky (USA), between August 2020 and March 2021, and parameterized an existing nowcasting model using combinations of these data. We assessed the predictive performance and variability at the sewershed level and compared the effects of adding or replacing wastewater data to case and death reports. …

An Evolutionary Pathway For Coping With Emerging Infectious Disease, Scott Lyell Gardner, Daniel R. Brooks, Walter A. Boeger, Eric P. Hoberg

Zea E-Books Collection

Emerging infectious disease (EID) represents an existential threat to humanity. EIDs are increasing in frequency and impact because of climate change and other human activities. We are losing the battle against EIDs because of improper assessment of the risk of EID. This stems from adherence to a failed paradigm of pathogen-host associations that suggests EIDs ought to be both unpredictable and rare. That, in turn, leads to policies suggesting that crisis response is the best we can do. Real-time and phylogenetic assessments show EIDs to be neither rare nor unpredictable—this is the parasite paradox that shows the failures of the …

‘Safe Couch, Safe House’ Program (Scshp): Reducing Exposure To Toxic Flame Retardants For Children In A Low-Income Public Housing At Hunters View, Bayview-Hunters Point, San Francisco., Aliza Khan

Master's Projects and Capstones

Since the 1970s, flame retardants have been used extensively in consumer goods, including furniture, textile, and electronics, to meet California’s flammability standards. (Gibson et al.,2019) Polybrominated Diphenyl Ethers (PBDEs), once the most widely used flame retardants being used in consumer products, were phased out from use in manufacturing as evidence emerged about PBDEs persistence and toxicity. (Hoffman et al.,2017) PBDEs were replaced by Organophosphate Flame Retardants (OPFRs), which has proven to be a case of ‘regrettable substitution’ as exposure to OPFRs is ubiquitous and pervasive in humans due to their volatility and propensity to leach from products into the environment. …

Occupational Exposures Associated With Thyroid Cancer In The Thyroid Tumor And Cancer Collaborative Registry In The Integrated Cancer Center Repository For Cancer Research, James Buckley

Capstone Experience

Thyroid cancer is one of the fastest growing cancers in the United States, with the rate of new cases increasing from 5.2 per 100,000 in 1985 to 13.8 per 100,000 in 2019, with a peak of 14.5 per 100,000 in 2015. Increased thyroid cancer incidence is associated with certain occupations, including healthcare and agriculture. Most existing literature on occupational exposures and thyroid cancer evaluate their association in terms of occupation type and thyroid cancer, rather than specific occupational exposures and thyroid cancer. This study sought to utilize the wide range of occupational exposure data in the Integrated Cancer Center Repository …

Investigation Of Orthohantavirus Genetics In Rodent Reservoirs And Clinical Samples, Samuel M Goodfellow

Biomedical Sciences ETDs

Orthohantaviruses are negative-sense, single stranded RNA viruses with trisegmented genomes that can cause severe disease in humans and are carried by several host reservoirs throughout the world. In the United States, Sin Nombre orthohantavirus (SNV) is the primary cause of hantavirus cardiopulmonary syndrome (HCPS) with a fatality rate of ~36% and the highest cases occuring in the southwest region. The primary SNV host reservoir is thought to be the western deer mouse, Peromyscus maniculatus, however it has been shown that other rodents can carry different orthohantaviruses. We designed a pan-orthohantavirus detection tool to survey several small mammal populations throughout New …

Household Environments And Functional Decline Among Middle-Aged And Older Adults In China, Dandan Zhao

All Theses

This thesis investigates the associations between household social, economic, and physical environment conditions and the trajectory of self-reported functional limitations over time among middle-aged and older adults in China. Despite the increasing interest in the impact of household environments on functional decline, most existing studies are cross-sectional or concern changes in functioning observed in two waves of surveys, and they primarily focus on the influence of one condition. This thesis explores how the trajectory of functional decline is influenced jointly by multiple household factors, including living arrangement, annual living expenditure per capita, indoor air pollution resulting from solid fuels, and …

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 …
