    Abstract:

    Background: Although many studies demonstrated reduced mortality risk with higher greenness, few studies examined the modifying effect of greenness on air pollution–health associations. We evaluated residential greenness as an effect modifier of the association between long-term exposure to fine particles (PM2.5) and mortality.

    Methods: We used data from all Medicare beneficiaries in North Carolina (NC) and Michigan (MI) (2001–2016). We estimated annual PM2.5 averages using ensemble predicti…

    Abstract:

    We develop a local, spatial measure of educational isolation (EI) and characterize the relationship between EI and our previously developed measure of racial isolation (RI). EI measures the extent to which non-college educated individuals are exposed primarily to other non-college educated individuals. To characterize how the RI-EI relationship varies across space, we propose a novel measure of local correlation. Using birth records from the State of Michigan (2005–2012), we estimate associat…

    Abstract:

    BACKGROUND AND AIM: Although previous literature suggested beneficial impacts of residential greenness on the association between heat exposure and several health outcomes, research is very limited for birth outcomes. We investigated the association between exposure to heat/heat waves during the last week of gestation and preterm birth (PTB) in North Carolina (NC) from 2003 to 2014. We evaluated disparities by residential greenness, urbanicity, and socioeconomic status (SES) in this associati…

    Abstract:

    We introduce spatial (DLfuse) and spatiotemporal (DLfuseST) distributed lag data fusion methods for predicting point-level ambient air pollution concentrations, using, as input, gridded average pollution estimates from a deterministic numerical air quality model. The methods incorporate predictive information from grid cells surrounding the prediction location of interest and are shown to collapse to existing downscaling approaches when this information adds no benefit. The spatial lagged par…

    Abstract:

    Social and environmental stressors are crucial factors in child development. However, there exists a multitude of measurable social and environmental factors—the effects of which may be cumulative, interactive, or null. Using a comprehensive cohort of children in North Carolina, we study the impact of social and environmental variables on 4th end-of-grade exam scores in reading and mathematics. To identify the essential factors that predict these educational outcomes, we design new tools for …

    Abstract:

    Estimating a massive drive time matrix between locations is a practical but challenging task. The challenges include availability of reliable road network (including traffic) data, programming expertise, and access to high-performance computing resources. This research proposes a method for estimating a nationwide drive time matrix between ZIP code areas in the U.S. - a geographic unit at which many national datasets including health information are compiled and distributed. The method (1) do…

    Abstract:

    As climate changes, coastal homeowners are potentially crucial actors in reducing the risks to property and human life from rising seas and increased hurricane activity. Absent strict, enforceable regulations mandating retrofitting of existing homes or major changes in homeowner insurance requirements, coastal resilience in a changing climate will largely reflect private, voluntary decisions of millions of individuals. However, research is scarce on the current risk level of U.S. coastal home…

    Abstract:

    ABSTRACT Pseudomonas aeruginosa is an opportunistic human pathogen important to diseases such as cystic fibrosis. P. aeruginosa has multiple quorum-sensing (QS) systems, one of which utilizes the signaling molecule 2-heptyl-3-hydroxy-4- quinolone (Pseudomonas quinolone signal [PQS]). Here, we use hyperspectral Raman imaging to elucidate the spatiotemporal PQS distributions that determine how P. aeruginosa regulates surface colonization and its response to both metabolic stress and competition…

    Abstract:

    BACKGROUND: Making landfall in Rockport, Texas in August 2017, Hurricane Harvey resulted in unprecedented flooding, displacing tens of thousands of people, and creating environmental hazards and exposures for many more.

    OBJECTIVE: We describe a collaborative project to establish the Texas Flood Registry to track the health and housing impacts of major flooding events.

    METHODS: Those who enroll in the registry answer retrospective questions regarding the impact of storms on their health and …
