Long-term prognosis of pregnancies complicated by slow embryonic heart rates in the early first trimester.
Slow embryonic heart rates at gestational age 7 weeks or less are associated with high risk of first trimester death. Our goal was to determine the prognosis for those embryos with slow early heart rates who survive the first trimester. We prospectively recorded embryonic heart rates for all obstetrical sonograms obtained on singleton pregnancies at or before 7.0 weeks' gestation since 1993. We...
متن کاملFirst-trimester serum marker distribution in singleton pregnancies conceived with assisted reproduction.
OBJECTIVE To evaluate marker distribution of free beta-human chorionic gonadotrophin (fbeta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in singleton pregnancies conceived by assisted reproduction techniques (ART). METHODS In vitro fertilization (IVF) (n = 203) and intracytoplasmic sperm injection (ICSI) (n = 192) cases from a database of 14 645 first-trimester combined tests (over...
متن کاملFirst trimester serum angiogenic/anti-angiogenic status in twin pregnancies: relationship with assisted reproduction technology.
BACKGROUND The risk of pre-eclampsia (PE) increases in twin pregnancies, especially when assisted reproduction technologies (ART) are used. The aim of this study was to assess angiogenic/anti-angiogenic factors in maternal serum in the first trimester of twin pregnancies and establish if the mode of conception influences angiogenic status. METHODS This prospective study enrolled women with tw...
متن کاملFactors predicting a positive pregnancy screening test at first trimester
Background: For every pregnant woman, it is possible to have a child with chromosomal abnormalities. Although this possibility is not very high, by performing screening tests and considering the mother's background factors, we can largely realize the real extent of this possibility. Many comorbidities (like high blood pressure, diabetes, and obesity) and high-risk exposures (like alcohol consu...
