Effects of High Altitude on AMPK Activation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Pregnancy elicits adaptive changes in uteroplacental blood flow, which are altered at high altitude and may contribute to the observed 3-fold increase in intrauterine growth restriction (IUGR) and preeclampsia (PreE). The investigators propose to collect myometrial, cord blood, and placental tissue samples from women at high altitude (Summit County) and low altitude (Denver) in Colorado in order to determine if residence at altitude during pregnancy changes the vasoreactivity of myometrial arteries (MA). If altered MA vasoreactivity is found, further studies may be able to link these changes to the increased rates of PreE and IUGR at altitude and contribute to the understanding of these two disorders.

Accepts Healthy Volunteers:Yes
Standard Ages:ADULT
Inclusion CriteriaExclusion Criteria
  1. * Women scheduled for cesarean delivery at University of Colorado Hospital (Denver, 1600 m) and St. Anthony's Summit Medical Center (Summit County, 3000 m)
  2. * Cesarean delivery at a prescheduled time without any labor, typically at 39 weeks gestation
  1. * Women will be excluded if there are co-existing medical diagnoses that are known to affect vascular parameters (i.e., diabetes mellitus, gestational diabetes, any hypertensive disorder of pregnancy, or a current smoker).
  2. * Women with multiple gestations and preterm deliveries will also be excluded.
