    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:

    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 …

    Abstract:

    Abstract Background Persistent disparities in academic performance may result from a confluence of adverse exposures accruing disproportionately to specific subpopulations.

    Objective Our overarching objective was to investigate how multiple exposures experienced over time affect early childhood educational outcomes. We were specifically interested in whether there were: racial/ethnic disparities in prevalence of adverse exposures; racial/ethnic disparities in associations observed between ad…

    Abstract:

    Background Several studies have reported environmental disparities regarding exposure to concentrated animal feeding operations (CAFOs). Public health implications of environmental justice from the intensive livestock industry are of great concern in North Carolina (NC), USA, a state with a large number and extensive history of CAFOs.

    Objectives We examined disparities by exposure to CAFOs using several environmental justice metrics and considering potentially vulnerable subpopulations.

    Abstract:

    Summary What is already known about this topic?

    Although various implementation strategies for SARS-CoV-2 testing on college and university campuses have been described, little has been published regarding successful responses to COVID-19 outbreaks on campus.

    What is added by this report?

    In response to a COVID-19 outbreak on a university campus in August 2020, rapid implementation of multiple measures, including aggressive testing, tracing, and isolation; enhanced data systems; and commun…

    Abstract:

    Objective: We applied a social network approach to examine if three types of diabetes-related stigma (self-stigma, perceived stigma and enacted stigma) moderated associations between social network characteristics (network size, kin composition, household composition, and network density), social support, and blood glucose among Ghanaians with type 2 diabetes mellitus (T2DM). Methods: Data were obtained through a cross-sectional survey of 254 adults at a diabetes clinic in Ghana that assessed…

    Abstract:

    Changes to water resources are critical to all sectors of the economy. Climate change will affect the timing and quantity of water available in the environment as well as have an adverse effect on the quality of that water. Floods, droughts, and changing patterns of water scarcity-when water is not available in sufficient enough quantities or of a suitable quality at the right time to fulfill demand-are all critical factors when considering how and where Indiana will be able to economically d…

    Abstract:

    Temperature constrains the transmission of many pathogens. Interventions that target temperature-sensitive life stages, such as vector controlmeasures that kill intermediate hosts, could shift the thermal optimum of transmission, thereby altering seasonal disease dynamics and rendering interventions less effective at certain times of the year and with global climate change. To test these hypotheses, we integrated an epidemiological model of schistosomiasis with empirically determined temperat…

    Abstract:

    Both increases in temperature and changes in precipitation may limit future tree growth, but rising atmospheric CO2 could offset some of these stressors through increased plant Water Use Efficiency (WUE). The net balance between the negative impacts of climate change and positive effects of CO2 on tree growth is crucial for ecotones, where increased climate stress could drive mortality and shifts in range. Here, we quantify the effects of climate, stand structure, and rising CO2 on both annua…

    Abstract:

    Continuous culture systems allow for the controlled growth of microorganisms over a long period of time. Here, we develop a novel test for mutagenicity that involves growing yeast in continuous culture systems exposed to low levels of mutagen for a period of approximately 20 days. In contrast, most microorganism-based tests for mutagenicity expose the potential mutagen to the biological reporter at a high concentration of mutagen for a short period of time. Our test improves upon the sensitiv…
