Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Summary

This summary is machine-generated.

The Danish selective screening program for small-for-gestational-age (SGA) fetuses has improved but has limitations. False diagnoses of SGA increased labor induction and cesarean sections.

Area of Science:

Obstetrics and Gynecology
Perinatal Medicine
Fetal Medicine

Background:

Accurate antenatal identification of small-for-gestational-age (SGA) fetuses is crucial for reducing adverse perinatal outcomes.
Ultrasound estimates of fetal weight (EFW_us) are the primary tool for SGA identification.
Denmark employs a selective screening approach for SGA, unlike universal screening.

Purpose of the Study:

To evaluate the performance of the Danish national SGA screening program.
To assess the consequences of false-positive and false-negative SGA diagnoses.

Main Methods:

Retrospective cohort study of 2928 singleton pregnancies from 2015.
Defined "risk of SGA" as EFW_us ≤ -15% and "SGA" as birthweight ≤ -22% of expected for gestational age.

Main Results:

The Danish SGA screening program demonstrated a sensitivity of 62% with a 5.6% false-positive rate.
Screening sensitivity varied by gestational age at birth (79% preterm vs. 40% post-term) and SGA severity.
False SGA diagnoses were associated with increased rates of labor induction (OR_adj=2.51) and cesarean section (OR_adj=1.44).

Conclusions:

The Danish selective SGA screening program has improved over two decades.
Limitations include a high referral rate for ultrasound and reduced performance in post-term pregnancies.
False SGA diagnoses contribute to increased interventions like labor induction and cesarean delivery.
