Validation of correction factors for serum markers for first-trimester Down syndrome screening in singleton pregnancies conceived with assisted reproduction.
OBJECTIVE To validate previously computed correction factors for free β-human chorionic gonadotrophin (fβ-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies with hormone treatment and to determine the effect on false-positive rate (FPR). METHODS Retrospective study on 249 IVF and 250 ICSI cases and 20...
متن کاملOutcomes of assisted reproduction treatment after dopamine agonist -cabergoline- for prevention of ovarian hyper stimulation syndrome
Background: Release of vascular endothelial growth factor (VEGF) by ovaries in response to HCG administration is one of the main mechanisms of ovarian hyper stimulation syndrome. Since Dopamine/dopamine receptor2 (Dp-r2) pathway activity -mediated by VEGF/ Vascular endothelial growth factor receptor 2 (VEGFR-2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...
متن کاملFirst trimester biochemical screening for Down's syndrome in singleton pregnancies conceived by assisted reproduction.
BACKGROUND Serum biochemical markers [free betahCG (fbetahCG); pregnancy-associated plasma protein-A (PAPP-A)] used in first trimester Down's syndrome screening have not been fully investigated in pregnancies achieved by assisted reproduction techniques. We present data on pregnancies conceived by all types of assisted reproduction techniques, including pregnancies following ovum donation (OD) ...
متن کاملIndependent prognostic factors for AML outcome.
Over the last three decades there have been dramatic advances in deciphering the cytogenetic and molecular lesions underlying the pathogenesis of acute myeloid leukemia (AML). These have not only afforded greater insights into disease biology, but also provided useful information predicting the likelihood of any given patient achieving and maintaining remission following conventional chemothera...
متن کاملAn update on antenatal screening for Down's syndrome and specific implications for assisted reproduction pregnancies.
Since the introduction of antenatal serum screening for Down's syndrome (DS) more than two decades ago, several screening approaches have been utilized in routine clinical practice. The current DS screening strategies involve mid-trimester serum biochemistry tests, first trimester tests combining sonographic markers and serum biochemistry and integration of first and second trimester markers. I...
