The use of serum human chorionic gonadotropin (hCG) and progesterone to identify patients with ectopic pregnancy (EP) has been shown to have poor clinical utility. Pregnancy-associated circulating microRNAs (miRNAs) have been proposed as potential biomarkers for the diagnosis of pregnancy-associated complications. This proof-of-concept study examined the diagnostic accuracy of various ...

Progesterone is produced by the corpus luteum until completion of the luteal-placental shift at approximately 6-10 weeks following last menstruation. Studies have shown that first trimester progesterone levels are predictive of pregnancy viability, and some authors support a level of 5 ng/mL as an absolute threshold to indicate viability. A ...

Preterm delivery (PTD) occurs before the 37th week of gestation. Iron deficiency anemia and inflammatory processes either related to infection or sterile inflammatory response represent risk factors for PTD. Bovine lactoferrin (bLf), an emerging important regulator of iron and inflammatory homeostasis, can represent a new therapeutic approach for PTD treatment. ...
