Low-Level Pm2.5 Exposure And Mortality In The Medicare Cohort: The Role Of Native American Beneficiaries, Judy Wendt Hess, Wenyaw Chan

Faculty, Staff and Student Publications

Fine particulate matter (PM2.5) has been associated with mortality at low concentrations, with higher per-unit risk at lower exposure levels, and no threshold of effect. We examined characteristics of Medicare decedents living in zip codes at the lowest end of the U.S. PM2.5 exposure distribution to determine whether there is a demographic, health or exposure profile of beneficiaries for whom even low PM2.5 exposure is associated with increased mortality. The study included 2,773,647 decedent cases and 27,736,470 non-decedent controls, matched on decile of long-term PM2.5 exposure from among 36 million Medicare fee-for-service beneficiaries enrolled 2015–2016. Outcomes of the study included …

Beyond Smoking: A Geospatial Investigation Of Factors Associated With Lung And Bronchus Cancer Risk In Pennsylvania, Tesla D. Dubois, Daniel Wiese, Kevin A. Henry, Shannon M. Lynch

Kimmel Cancer Center Faculty Papers

INTRODUCTION: While smoking is the leading cause of lung and bronchus cancer (LBC), additional exposures have been implicated and may explain the rise in LBC among never-smokers. To better understand the spatial distribution of LBC incidence and associated risk factors, this study aims to identify geographic areas with significantly elevated incidence rates in Pennsylvania and investigate the potential underlying risk factors.

METHODS: Using cancer registry data aggregated to the census tract level, spatial scan statistics were applied to detect areas of higher-than-expected LBC incidence across the state. Associations were then tested between census tract inclusion in a high-incidence area and …

Differential Mirna Expressions Linking Environmental Risk Factors To Triple-Negative Breast Cancer Stages At Diagnosis, Amjila Bam, Yawen Hu, Xiaocheng Wu, Meng Luo, Nubaira Rizvi, Luis Del Valle, Arnold H. Zea, Fokhrul Hossain, Denise Moore Danos, Jovanny Zabaleta, Augusto Ochoa, Lucio Miele, Edward Trapido, Qingzhao Yu

School of Public Health Faculty Publications

Background/Objectives: Triple negative breast cancer (TNBC) is an aggressive, molecularly heterogeneous subtype of breast cancer, accounting for approximately 10–15% of all cases. While reproductive and metabolic factors contribute to breast cancer development, growing concerns about environmental exposures, alongside biological and socio-cultural influences, underscore the need for targeted prevention strategies across diverse populations. Despite increasing evidence linking biological, socioeconomic, and environmental factors to TNBC outcomes, the molecular mechanisms underlying these relationships remain poorly understood. Micro-RNAs (miRNAs), which regulate gene expression and play critical roles in cancer development, have emerged as potential mediators between environmental exposures and TNBC progression. The goal of …

Frontier Healthscapes: Competing Narratives Of Disease, Environment, And Wellbeing In Early Minnesota, Aidan Reynolds

Geography Honors Projects

Across settler societies, health narratives were shaped by evolving tensions between lay and expert knowledge, frameworks of disease causation, and perceptions of the environment as both a source of health and a threat. In the decades following Euro-American settlement (1860-1900), Minnesota became a focal point for these debates, with its landscape fostering complex and competing narratives on health, wellbeing, and disease. This paper explores how public health discourse developed in Minnesota through the perspectives of institutions, the public, and economic interests. Combining environmental history with critical discourse analysis of archival materials, this study examines shifts within the Minnesota State Board …

Bioavailability Of Lead In Terre Haute Soils, Terre Haute, Indiana, Zach Kemp

All-Inclusive List of Electronic Theses and Dissertations

Contamination of soils from heavy metal pollution has been a global concern for decades. Heavy metals are released into the soil from natural and anthropogenic releases. The largest producers of heavy metal pollution include mining, industrial production, and the combustion of fossil fuels. Vigo County formed in 1818, and Terre Haute was established in 1832. After the discovery of coal in Clay County in 1867, Terre Haute became the third largest coal producer and fifth largest iron manufacturer in the state during that time. Lead, in particular, is a heavy metal of concern because of the harmful effects to humans …

For decades, the dominant approach to lead poisoning has been to focus on homes affected by lead paint and to treat children who are already suffering from lead poisoning. This individualizing approach developed in the context of the defunding and deregulation of government agencies in the 1980s. In recent years, however, community–academic partnerships have reframed lead as an environmental issue produced by the development of the lead industry in the twentieth century and connected to overlapping histories of exploitation, discrimination, and inaction. These community-based projects have contributed to shifting research agendas (by emphasizing historical analysis and the study of the …

Revitalizing Passenger Rail: A Sustainable Solution To Environmental And Public Health Challenges In South Carolina, Benjamin Cochran

Theses and Dissertations

South Carolina, a historic leader in passenger rail, has become a heavily vehicle-dependent state. As the population rapidly grows, so does the number of vehicles, vehicle miles traveled, and vehicle emissions, including the greenhouse gas pollutants carbon dioxide (CO2), nitrous oxide (N2O), and particulate matter (PM2.5), significantly contributing to air pollution and deteriorating health and environmental outcomes. Despite this, mass transit is nonexistent for the three largest cities in South Carolina, Charleston, Columbia, and Greenville, forcing residents and travelers to drive. This study evaluates the feasibility and the environmental, public health, environmental justice, and economic implications of a passenger rail …

Bero, Roger Chou, Devon C. Payne-Sturges, Wendy E. Wagner, Jessica W. Reyes, Lisa M. Askie, Daniel A. Axelrad, Deysi Flores Vigo, Jill E. Johnston, Juleen Lam, Keeve E. Nachman, Eva Rehfuess, Rachel Rothschild, Patrice Sutton, Lauren Zeise, Tracey J. Woodruff

Articles

Environmental exposures, including widespread industrial pollution, impact human health and are amplified in more highly exposed communities. Policy and regulatory frameworks for making decisions and recommendations on interventions to mitigate or prevent exposures tend to narrowly focus on exposure and some health-related data related to risks. Typically, such frameworks do not consider other factors, including essentiality, health equity, and distribution of benefits and costs. Further, decisions and recommendations lack transparency regarding how they were developed. We developed the Navigation Guide Evidence-to-Decision Framework for Environmental Health (E2DFEH) to provide a structured and transparent framework incorporating a range of scientific information and …

The Healing Power Of Antitrust, Theodosia Stavroulaki

Northwestern University Law Review

Millions of Americans live in hospital deserts—communities where people lack geographic access to hospitals and primary care physicians. People living in these deserts often miss doctor appointments, delay necessary care, and stop adhering to their treatment. In this way, hospital deserts exacerbate the health disparities plaguing America. This Article demonstrates that hospital deserts are not inevitable but the result of several business strategies—including noncompete agreements and merging with competitors—and antitrust enforcers’ unwillingness to recognize these harmful practices as antitrust violations. To cure the issue of hospital deserts, this Article makes three proposals. First, antitrust enforcers and the courts should expand …

From Fields To Fast Foods: Food Culture, Identity, And Health In Puerto Rico Under The U.S. Empire, Ivanna Morales Mercado

CMC Senior Theses

Operation Bootstrap, launched in 1947, fundamentally altered Puerto Rico’s economy, just as much as its food culture. Prioritizing manufacturing over agriculture led to the collapse of the island’s farming sector, increasing reliance on food imports and leading to a rise in diet-related diseases such as obesity, type 2 diabetes, and cardiovascular issues. This thesis examines the legacies of Operation Bootstrap on Puerto Rico’s food system, health outcomes, and cultural identity by emphasizing the need to value intergenerational knowledge. The oral history research in this study highlights the importance of intergenerational knowledge in reclaiming sustainable agricultural practices and healthy, culturally significant …
