Evaluating the Justice and Risk Dimensions of Ethylene Oxide Governance in the US.

We investigate the governance and environmental justice (EJ) outcomes from the hazard reclassification of ethylene oxide (EtO) by the Environmental Protection Agency in 2016. In response to EtO pollution after 2018, federal and state regulators engaged constituents to respond to complaints about EtO but adhered to a cost-benefit governance approach that ultimately inhibited risk mitigation. We argue risk mitigation was constrained by path dependent approaches that simultaneously enabled recognition of constituent concerns about EtO pollution while minimizing the costs of institutional change.

Prenatal black carbon exposure and DNA methylation in umbilical cord blood.

Background/objectives: Prenatal exposure to ambient air pollution is associated with adverse cardiometabolic outcomes in childhood. We previously observed that prenatal black carbon (BC) was inversely associated with adiponectin, a hormone secreted by adipocytes, in early childhood. Changes to DNA methylation have been proposed as a potential mediator linking in utero exposures to lasting health impacts.

Independent and joint effects of neighborhood-level environmental and socioeconomic exposures on body mass index in early childhood: The environmental influences on child health outcomes (ECHO) cohort.

Past studies support the hypothesis that the prenatal period influences childhood growth. However, few studies explore the joint effects of exposures that occur simultaneously during pregnancy. To explore the feasibility of using mixtures methods with neighborhood-level environmental exposures, we assessed the effects of multiple prenatal exposures on body mass index (BMI) from birth to age 24 months.

Beyond the Imodium, a One Health Discussion on Diarrhea and the Impact of Climate Change.

Our ability to tackle the looming human, animal, and global ecosystem health threats arising from the issues of climate change and extreme weather events will require effective and creative cross-disciplinary collaboration. There is a growing national and international interest in equipping the next generation of clinicians and health scientists for success in facing these important challenges by providing interprofessional training opportunities. This paper describes how we assembled an interdisciplinary team of experts to design and deliver a case-based discussion on a cross-species illness outbreak in animals and humans using a One Health framework.

Early-life exposure to residential black carbon and childhood cardiometabolic health.

Background: Early life exposure to air pollution, such as particulate matter ≤2.5 μm (PM), may be associated with obesity and adverse cardiometabolic health outcomes in childhood. However, the toxicity of PM varies according to its chemical composition.
