Alterations of natriuretic peptides amino-terminal pro B-type natriuretic peptide and amino-terminal pro C-type natriuretic peptide during the pregnancy.
The aim of this study was to determine the plasma levels of natriuretic peptides amino-terminal pro B-type natriuretic peptide (NT proBNP) and amino-terminal pro C-type natriuretic peptide (NT proCNP) during pregnancy and any possible changes occurring in each trimester. ⋯ This is the first study evaluating the longitudinal levels of NT proCNP during the pregnancy, and demonstrates that NT proCNP remained constant, but NT proBNP levels do not significantly alter during pregnancy.

The fetal head evaluation during labor in the occiput posterior position: the ESA (evaluation by simulation algorithm) approach.
The determination of fetal head position can be useful in labor to predict the success of labor management, especially in case of malpositions. Malpositions are abnormal positions of the vertex of the fetal head and account for the large part of indication for cesarean sections for dystocic labor. The occiput posterior position occurs in 15-25% of patients before labor at term and, however, most occiput posterior presentations rotate during labor, so that the incidence of occiput posterior at vaginal birth is approximately 5-7%. ⋯ By these evidences, the time requested for fetal head descent and the position in the birth canal, had an impact on the diagnosis of labor progression or arrested labor. To try to reduce this pitfalls, authors developed a new algorithm, applied to intrapartum US and based on suitable US pictures, that sets out, in detail, the quantitative evaluation, in degrees, of the occiput posterior position of the fetal head in the pelvis and the birth canal, respectively, in the first and second stage of labor. Authors tested this computer system in a settle of patients in labor.

The impact of loop electrosurgical excision procedure (LEEP) for CIN 2,3 on spontaneous preterm delivery in twin pregnancies by assisted reproductive technique: preliminary data.
The objective of this study was to compare the frequency of spontaneous preterm delivery before 35 weeks in 7 dichorionic twin pregnancies obtained after loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 2,3 with respect to 21 twin pregnancies without previous cervical treatment. All the pregnancies were obtained after assisted reproduction techniques (ART). Same age at delivery was observed between two groups (p = 0.81) and none of our twin pregnancies after LEEP had a threatened preterm labor while four controls (19%) underwent a spontaneous preterm delivery (p = 0.35). These preliminary data seem to indicate that LEEP may not be responsible of spontaneous preterm delivery in twin pregnancies subsequent to ART.

First trimester maternal serum vitamin D and markers of preeclampsia.
There is evidence that vitamin D deficiency is associated with preeclampsia. The aim of the study was to determine if maternal levels of vitamin D at 1st trimester were related to markers of preeclampsia. ⋯ First trimester maternal serum concentration of vitamin D does not seem to be connected with markers of preeclampsia.
