Built Environment and Preterm Birth

Additive Interaction between Heterogeneous Environmental Quality Domains (Air, Water, Land, Sociodemographic, and Built Environment) on Preterm Birth

BACKGROUND Environmental exposures often occur in tandem; however, epidemiological research often focuses on singular exposures. Statistical interactions among broad, well-characterized environmental domains have not yet been evaluated in association with health. We address this gap by conducting a county-level cross-sectional analysis of interactions between Environmental Quality Index (EQI) d...

Inflammation and preterm birth.

Preterm birth is the leading cause of neonatal morbidity and mortality. Although the underlying causes of pregnancy-associated complication are numerous, it is well established that infection and inflammation represent a highly significant risk factor in preterm birth. However, despite the clinical and public health significance, infectious agents, molecular trigger(s), and immune pathways unde...

Relaxin and preterm birth.

Preterm birth (PTB) is a global problem with a high incidence in the developing world. Relaxin (RLN) has classically been associated with parturition, but its role(s) in the human have been difficult to determine. For the first time, we bring together the systemic (ovarian) and autocrine/paracrine (intrauterine) sources of RLN, in an attempt to understand how RLN contributes to PTB in women.

Infection and preterm birth.

As many as 50% of spontaneous preterm births are infection-associated. Intrauterine infection leads to a maternal and fetal inflammatory cascade, which produces uterine contractions and may also result in long-term adverse outcomes, such as cerebral palsy. This article addresses the prevalence, microbiology, and management of intrauterine infection in the setting of preterm labor with intact me...
