Second-trimester levels of pregnancy-associated plasma protein-A and free beta-hCG in pregnancies with trisomy 13.
OBJECTIVE To examine the levels of free beta-human chorionic gonadotrophin (free beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in second-trimester maternal serum from pregnancies affected by trisomy 13 and compare these with the known reduced levels of these markers in first-trimester cases in an attempt to better understand the pathophysiology of changes in marker levels in chro...
متن کاملMaternal serum levels of interleukin-6 and β-hCG in women with hyperemesis gravidarum in the first trimester of pregnancy
Background and Objective: Hyperemesis gravidarum (HG) is defined as vomiting sufficiently severe to produce weight loss, dehydration, electrolyte abnormalities. Interleukin-6 (IL-6), a pro-inflammatory and trophoblast-derived cytokine has ability to induce trophoblasts to secrete human chorionic gonadotropin (hCG).

study more than a third of the abused women had been admitted five times or more. The greater differences in admissions in the ages over 30 might be related to ongoing domestic violence. Several studies indicate that the risk ofbeing the victim of wife beating is most pronounced in the fourth decade of life.' 24 The abused woman, in her exposed and desolate situation, does not always seek medic...
متن کاملFirst-trimester maternal serum pregnancy-associated plasma protein-A and pre-eclampsia.
OBJECTIVES To examine the relationship between low maternal serum pregnancy-associated plasma protein-A (PAPP-A) and uterine artery pulsatility index (UtA-PI) at 11+0 to 13+6 weeks with subsequent development of pre-eclampsia (PE). METHODS UtA-PI and serum PAPP-A were measured in women attending for routine care at 11+0 to 13+6 weeks of gestation. In the population, 156 (1.9%) women developed...
متن کاملThe relationship between first-trimester pregnancy-associated plasma protein-A levels and intrapartum fetal distress development.
OBJECTIVE To investigate the relationship between the development of intrapartum fetal distress and serum pregnancy-associated plasma protein-A (PAPP-A) levels measured during first-trimester aneuploidy screening tests. MATERIAL AND METHODS This retrospective study included 283 uncomplicated pregnancies that resulted in full-term live births via spontaneous labor or with the induction by oxyt...
