Zika virus (ZIKV) vertical transmission results in devastating congenital malformations and pregnancy complications; however, the specific receptor and host factors facilitating ZIKV maternal-fetal transmission remain elusive. Here, we employ a genome-wide CRISPR screening and identify multiple placenta-intrinsic factors modulating ZIKV infection. Our study unveils that hepatitis A virus cellular receptor 1 (HAVCR1) serves as a primary receptor governing ZIKV entry in placental trophoblasts. The GATA3-HAVCR1 axis regulates heterogeneous cell tropism in the placenta. Notably, placenta-specific Havcr1 deletion in mice significantly impairs ZIKV transplacental transmission and associated adverse pregnancy outcomes. Mechanistically, the immunoglobulin variable-like domain of HAVCR1 binds to ZIKV via …

How To Kill A Human: Creating An Immersive Learning Game, Théo Caldwell, Nathan Bonnell

OHSU-PSU School of Public Health Annual Conference

How to Kill a Human is an experiment in teaching through gameplay. The environmental crisis facing the planet, though denied by many, is a collection of well-documented historical environmental catastrophes. The purpose of this project was to design a method of relating the impacts of environmental systems on human health, highlighting the dangers of ill planned human tampering, by presenting hypothetical environmental catastrophes and then relating them to documented historical disasters. In pursuit of this goal, we designed a semi-collaborative game for three to six players with a suggested age rating of 10+, ideal for teaching individuals of middle school …

Association Between Arsenic And Other Heavy Metal Exposures Through Drinking Water And Food With Lung Function And Respiratory Symptoms: A Cross-Sectional Study, Sofia I. Chapela Lara, Seth O'Neal Md, Mph For The Cysticercosis Working Group In Peru

OHSU-PSU School of Public Health Annual Conference

Impaired lung function is a major health concern, particularly in children, as it increases the risk of chronic respiratory diseases and long-term morbidity. Environmental exposure to heavy metals (HMs) such as arsenic, lead, cadmium, and manganese has been associated with reduced lung function and respiratory symptoms. However, findings vary by exposure context and population, with limited research in pediatric populations and few studies evaluating the combined effects of multiple HMs. These exposures disproportionally affect marginalized rural communities, especially in low and middle-income countries with mining activities. This cross-sectional study investigated the association between exposure to As and other HMs through …

Prenatal Exposure To Pm2.5 Concentration And Risk Of Preterm Birth In New Mexico; A Seasonal Pattern And Spatio-Temporal Modeling., Onyedikachi J. Okeke

Mathematics & Statistics ETDs

This study investigates the association between prenatal PM2.5 exposure and preterm birth risk in New Mexico (2014–2021). Using descriptive statistics, time series models, and spatial analyses, findings show an average preterm birth rate of 14.87 per 1,000 live births, with moderate correlation (r = 0.727) between PM2.5 levels and very preterm births. While traditional models revealed no significant global effect, spatial methods such as Geographically Weighted Regression (GWR) and Multiscale GWR uncovered strong spatial heterogeneity. PM2.5 effects varied by county (coefficients: -0.00154 to 0.00150), with clustering evident in 2018–2019 (Moran’s I = 0.155–0.174). Results highlight the limitations of global models …

Growing The Good: A Communal Garden Case Study Among Marginalized, Rural Populations, Claire Barbier

LSU Master's Theses

Community and Communal gardens (CG) have been documented as early as the late 1800s during periods of economic recessions and high food insecurity (The MIT Press Reader, 2022). However, C.G. adoption rates are expanding on a global scale as communities and municipalities see the potential for the tool to bring relief to environments in dire need of additional resources. Utilizing a communal garden can be used to address a surplus of systemic barriers a community faces; it has a significant opportunity to bring forth the interconnected tiers of public health altogether (Twiss et. al, 2003). Modernized C.G projects bring forth …

Lead Telecommunications Cables: A Call For Concern?, Zachary Young

Michigan Journal of Environmental & Administrative Law

From the late 1800s until the 1950s, telecommunication companies across the United States utilized lead casing to protect their telecommunication lines. As technology developed and different types of plastic coatings were created, telecommunication companies phased out the use of lead cables. However, the lead cables remain in the air and buried in the ground, even continuing to provide telephone service for some. The failure to remove these cables, most of which are not in use anymore, has generated a slew of issues for the modem-day telecommunication companies that have inherited these cables from their predecessors. As the protective casing decays, …

Investigating Mercury Contamination In Urban Fish: Atomic Absorption Spectroscopy And Histological Analysis For Environmental And Human Health, Indy L. Cockrill, Ross Andrew

SPARK Symposium Presentations

Mercury contamination in aquatic ecosystems is a pressing environmental and public health concern, particularly in urban areas where industrial runoff and wastewater contribute to heavy metal accumulation. This study investigates mercury presence in fish from Richland Creek in Nashville, TN, by analyzing histological changes in liver and muscle tissues. Mercury bioaccumulates in aquatic food chains, potentially leading to physiological damage in fish and posing health risks to humans who consume contaminated seafood. While prior research has established mercury’s toxic effects, there is a need for localized studies assessing its presence in urban waterways. The hope is to find histological abnormalities …

We examined neuroimmune system effects in C57BL/6J mice with Pb exposure, including levels that may be common among children in lower socioeconomic income environments. Pups were exposed via dams’ drinking water from birth to post-natal day 28 to low, high or no Pb conditions. We compared gene expression of neuroinflammatory markers (study 1); and microglial mean cell body volume and mean cell body number in dentate gyrus, and dentate gyrus volume (study 2). Blood Pb levels in exposed animals at sacrifice (post-natal day 28) …

A Bland–Altman Comparison Of The Lead Care® System And Inductively Coupled Plasma Mass Spectrometry For Detecting Low-Level Lead In Child Whole Blood Samples, Christina Sobin, Tanner Schaub, Natali Parisi, Eva De La Riva

Departmental Papers (PH)

Chronic childhood lead exposure, yielding blood lead levels consistently below 10 μg/dL, remains a major public health concern. Low neurotoxic effect thresholds have not yet been established. Progress requires accurate, efficient, and cost-effective methods for testing large numbers of children. The LeadCare® System (LCS) may provide one ready option. The comparability of this system to the “gold standard” method of inductively coupled plasma mass spectrometry (ICP-MS) for the purpose of detecting blood lead levels below 10 μg/dL has not yet been examined. Paired blood samples from 177 children ages 5.2–12.8 years were tested with LCS and ICP-MS. Triplicate repeat tests …

Contraceptive Hormone Influences On The Role Of Primary Reinforcement And Reinforcer-Enhancement In Nicotine Self-Administration, Kathleen Robin Mcnealy

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Hormonal contraceptives contain a synthetic estrogen (e.g., ethinyl estradiol/EE) and/or a synthetic progestin (e.g., levonorgestrel/LEVO) and can exacerbate nicotine intake. However, whether altered intake reflects changes in nicotine reinforcement or enhancement by nicotine of co-occurring reinforcers is unknown. This reinforcer-enhancement effect is evidenced in rats when nicotine self-administration is increased by the presence of a visual stimulus (VS) reinforcer. This dissertation examined the effects of EE and LEVO on nicotine reinforcement and reinforcer-enhancement in ovary-intact female Sprague-Dawley rats. Rats were implanted with a jugular catheter and assigned to receive daily injections of EE (Vehicle, 0.125 [Low], or 0.18 [High] μg/day; …
