Multiple Comparison Tests01:13

Multiple Comparison Tests

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
Teratogenicity01:07

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...
Bioequivalence of Drugs: Drugs with Multiple Indications01:09

Bioequivalence of Drugs: Drugs with Multiple Indications

The concept of therapeutic equivalence (TE) in drugs with multiple indications is complex. A generic drug may be therapeutically equivalent to a brand-name product for one specific indication, but this doesn't necessarily mean it's equivalent for all other indications. Evidence of TE in one patient group and bioequivalence shown in healthy volunteers can support—but not confirm—TE for other indications. However, definitive proof requires individual clinical studies for each indication due to...

Summary

Multiple gestations, especially monochorionic twins, face higher risks. Early determination of gestation type and close follow-up imaging are crucial for monitoring fetal well-being and reducing complications.

Area of Science:

  • Maternal-Fetal Medicine
  • Diagnostic Imaging
  • Obstetrics

Background:

  • Multiple gestations carry increased risks compared to singleton pregnancies.
  • Monochorionic twins are particularly vulnerable to complications like twin-twin transfusion and fetal growth restriction.
  • Early identification of gestation type (multiple, amnionicity, chorionicity) is vital.

Purpose of the Study:

  • To highlight the importance of early determination of multiple gestation characteristics.
  • To emphasize the need for appropriate follow-up imaging and surveillance in multiple gestations.
  • To address the paucity of literature on recommended imaging schedules for twin pregnancies.

Main Methods:

  • Review of current medical literature on multiple gestations and fetal surveillance.
  • Application of the modified Delphi consensus methodology by a multidisciplinary expert panel.
  • Analysis of the ACR Appropriateness Criteria for imaging procedures in high-risk pregnancies.

Main Results:

  • Early determination of gestation type and chorionicity is essential.
  • Standard follow-up examinations include fetal growth assessment, amniotic fluid volume, umbilical artery Doppler, nonstress tests, and biophysical profiles.
  • In the absence of definitive evidence, expert opinion guides imaging recommendations.

Conclusions:

  • Close monitoring and appropriate imaging schedules are critical for managing high-risk multiple gestations.
  • Surveillance in multiple gestations should at least match that of singleton pregnancies.
  • Evidence-based guidelines, supplemented by expert opinion, are necessary for optimizing care.
