Teratogenicity01:07

Teratogenicity

4.5K
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...

Development of the Oral Microbiota

14
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Summary

Pregnant women overwhelmingly prefer early first-trimester screening results for fetal abnormalities. This includes even minor or suspected conditions, with maternal age and views on termination influencing responses.

Area of Science:

  • Maternal-fetal medicine
  • Prenatal screening
  • Obstetrics

Background:

  • The 11-13-week scan is crucial for detecting fetal structural abnormalities.
  • Understanding maternal preferences for receiving screening results is vital for informed consent and counseling.

Purpose of the Study:

  • To investigate maternal attitudes towards prenatal screening for fetal structural abnormalities based on abnormality severity.
  • To identify maternal characteristics influencing these attitudes.

Main Methods:

  • A descriptive study utilizing 300 self-administered questionnaires.
  • Questionnaires were completed by pregnant women before routine 11-13-week ultrasound scans.

Main Results:

  • Nearly all women (93.9%-96.6%) desired early knowledge of lethal or severe fetal abnormalities.
  • A high percentage (77.0%-91.2%) also preferred early disclosure of minor or suspected abnormalities.
  • Maternal age, gestational age, and attitude towards pregnancy termination significantly impacted responses.

Conclusions:

  • Pregnant women strongly prefer first-trimester disclosure of all fetal abnormalities, regardless of severity.
  • This preference underscores the importance of timely and comprehensive prenatal screening information.
