Article Synopsis
- Rare earth oxyhydrides (REOH) with rare earth elements like Y, Sc, or Gd exhibit reversible photochromism, meaning they can change color when exposed to light, but the exact mechanism behind this behavior remains unclear.
- The study utilizes advanced techniques such as solid-state NMR spectroscopy and density functional theory (DFT) calculations to analyze the roles of yttrium, hydrogen, and oxygen within the materials, revealing complex local environments and varying compositions among the hydride and hydroxide ions.
- Findings indicate the presence of both hydride-rich and hydride-poor domains in the samples, along with evidence of molecular hydrogen formation through reactions between hydroxide and hydride ions,
Introduction: When women with a previous cesarean section and an unfavorable cervix have an indication for delivery, the choice is to induce labor or to perform a cesarean section. This study aims to assess the effectiveness and safety of a balloon catheter as a method of induction of labor in women with one previous cesarean section and an unfavorable cervix compared with an elective repeat cesarean section.
Material And Methods: We performed a prospective cohort study in 51 hospitals in the Netherlands on term women with one previous cesarean section, a live singleton fetus in cephalic position, an unfavorable cervix and an indication for delivery.
Objective: In a recent randomized controlled trial we found that induction of labor in women with gestational hypertension (GH) or mild (preeclampsia) PE at term prevented high risk situations without increasing the cesarean section (CS) rate. We aimed to assess the predictability of the risk of CS.
Study Design: We used multivariable logistic regression analysis to identify predictive factors.
