Ambient air pollution is associated with graft failure/death in pediatric liver transplant recipients.

Children exposed to disproportionately higher levels of air pollution experience worse health outcomes. In this population-based, observational registry study, we examine the association between air pollution and graft failure/death in children following liver transplantation (LT) in the US. We modeled the associations between air pollution (PM) levels localized to the patient's ZIP code at the time of transplant and graft failure or death using Cox proportional-hazards models in pediatric LT recipients aged <19 years in the US from 2005-2015.

Outcomes of Patients With Negative Cervical Imaging but Persistent Neck Tenderness Discharged With a Rigid Collar After Trauma.

Introduction It is not uncommon for patients with persistent neck pain after trauma despite negative cervical imaging to be discharged with a rigid collar. Protocols for these patients vary widely. Few studies have evaluated clinical outcomes after discharge.
