Preventing preterm birth remains a challenge, as rates have increased despite tocolytic use. While fetal fibronectin and ultrasound are effective, home uterine monitoring has not proven beneficial for reducing preterm birth.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Medicine
  • Maternal-Fetal Medicine

Background:

  • Preterm birth is a primary cause of infant morbidity and mortality, with national rates near 11%.
  • Despite extensive use of tocolytic agents, the incidence of preterm birth has risen in the U.S. over the last three decades.
  • The etiology of preterm birth is multifactorial, involving potential insults to the uteroplacental barrier, fetal stress pathways, cervical incompetence, and uterine distention.

Purpose of the Study:

  • To review biochemical and biophysical markers for identifying women at risk of preterm delivery.
  • To evaluate the efficacy of various predictive methods in managing and preventing preterm birth.

Main Methods:

  • Review of existing studies on biochemical markers (e.g., fetal fibronectin, salivary estriol).

Related Experiment Videos

  • Analysis of biophysical markers, specifically endovaginal ultrasound assessment of cervical length.
  • Evaluation of home uterine activity monitoring systems.

    • Main Results:

    • Fetal fibronectin assays and endovaginal ultrasound are effective in identifying symptomatic women at low risk for preterm birth.
    • Salivary estriol shows promise as a reliable risk identifier in high-risk populations.
    • Home uterine activity monitoring has not demonstrated a reduction in preterm birth frequency or associated neonatal complications.

    Conclusions:

    • Certain markers, like fetal fibronectin and cervical ultrasound, are valuable tools for risk stratification in preterm birth prediction.
    • Further research is needed for markers such as salivary estriol to confirm their role in clinical practice.
    • Current evidence does not support the use of home uterine activity monitoring for preventing preterm birth.
