Body Mass Index and Levonorgestrel Device Expulsion in Adolescents and Young Adults.
J Pediatr Adolesc Gynecol
August 2024
Study Objective: To evaluate the relationship between body mass and levonorgestrel intrauterine device (LNG-IUD) expulsion in adolescents and young adults (AYA).
Design, Setting, Participants & Interventions: A retrospective chart review was conducted of nulliparous females aged 10-24 years who had a 52-milligram LNG-IUD placed between November 2017 and May 2021 by pediatric and adolescent gynecology providers at a tertiary children's hospital, including those who underwent metabolic and bariatric surgery (MBS). Primary analysis focused on 10-19 year olds as they had comparable anthropometrics (namely BMI percentile [BMIP] as defined by the Centers for Disease Control).
Background: Alabama's Human Life Protection Act (the Act) signed in 2019 became law in 2022, making provision of abortion a felony offense.
Objective: In 2020, we assessed the accessibility of emergency contraception (EC) pills in Birmingham, Alabama prior to the Act's enactment given the probable increased need for EC access due to abortion criminalization.
Study Design: Pharmacy staff were asked about availability, price, location, and identification requirements to obtain EC.
Article Synopsis
- Chronic high-altitude (HA) living decreases blood flow to the uterus during pregnancy, potentially leading to more cases of preeclampsia and restricted fetal growth.
- The study found that myometrial arteries (MAs) in HA women reacted differently to vasodilators than those at lower altitudes (LA), particularly showing impaired responses to acetylcholine.
- While bradykinin vasodilation was similar in both altitudes, the findings suggest that reduced nitric oxide (NO) signaling in HA women contributes to limited blood perfusion to the uterus during pregnancy.
