Associations between First Trimester Maternal Nutritional Score, Early Markers of Placental Function, and Pregnancy Outcome.

This study investigated the associations between maternal adherence to a healthy diet, first trimester placental markers, and pregnancy outcome. Singleton spontaneous pregnancies were enrolled at 11-13 gestational weeks in a prospective cohort study. A nutritional score (0-10) measuring the adherence to a healthy diet was calculated.

Evaluation of Uterine Artery Doppler and Estrogen Milieu in Oocyte Donation Pregnancies-A Pilot Study.

Oocyte donations (OD) represent 4.5% of all in vitro fertilization (IVF) cycles. While OD pregnancies face increased risks of obstetrical complications, especially pregnancy-induced hypertension and pre-eclampsia (PE), little is known about the physiology and the physiopathology of placentation.

Ultrasound in Infertility Setting: Optimal Strategy to Evaluate the Assessment of Tubal Patency.

Tubal patency is a key element in women who are undergoing assisted reproductive techniques (ART), in order to attempt or exclude intrauterine insemination (IUI) cycles. Amongst the different procedures that can be used, without resorting to laparoscopy that remains the gold standard, hystero-salpingo-contrast sonography (HyCoSy) is an acceptable, time-efficient, and well tolerated option; it can be performed with administration of saline and air simultaneously or alternately (air/saline-HyCoSy), or with some other contrast agents, like SonoVue (sulfur hexafluoride microbubbles). In this paper, we describe two different studies: in the first one, our aim is to compare the efficiency of air/saline-HyCoSy with HyCoSy performed with contrast media (SonoVue), considering hysterosalpingography (HSG) and laparoscopy (LPS) as reference tests; in the second one, we estimate the pregnancy rate of a cohort of infertile women selected to undergo IUI cycles after tubal bilateral patency demonstration with air/saline-HyCoSy, to understand if this technique can be used as an efficient screening procedure in a Reproductive Unit.

Uterine artery Doppler pulsatility index at 11-38 weeks in ICSI pregnancies with egg donation.

Background: Uterine artery Doppler pulsatility index (UtA-PI) may be different in pregnancies with egg donation (ICSI-ED) as compared to conceptions with autologous intra-cytoplasmatic sperm injection (autologous ICSI) and to spontaneous conceptions (SC).

Methods: One hundred and ninety-four pregnant women with different modes of conception (MC) were prospectively evaluated: 53 ICSI-ED, 36 autologous ICSI and 105 SC. To evaluate the effects of different MC on PI, multivariable linear regression (MLR) models predicting UtA-PI were fitted after adjustment for maternal age, body mass index, race, parity, smoking status and gestational age.

Maternal and fetal outcomes in oocyte donation pregnancies.

Background: Since the first successful use of donated oocytes in 1984, the number of oocyte donation cycles in Europe and the USA has dramatically increased. Consequently, there has been increasing interest in the impact of oocyte donation on maternal and fetal outcomes.

Objective And Rationale: The aim of this review was to summarize the literature regarding maternal and fetal outcomes from pregnancies conceived through oocyte donation.

First trimester placental markers in oocyte donation pregnancies.

Introduction: This study investigates the hypothesis that placenta works differently in oocyte donation (OD) compared to spontaneous pregnancies. To verify this hypothesis we examine the first trimester maternal serum levels of free β-hCG and pregnancy-associated plasma protein-A (PAPP-A). Then we evaluated for potential differences of Down syndrome screening between OD pregnancies, in vitro fertilization/intracytoplasmic sperm injection pregnancies with autologous oocytes (IVF/ICSI) and spontaneous pregnancies.

Imported Loa loa filariasis: three cases and a review of cases reported in non-endemic countries in the past 25 years.

Objectives: The aim of this study was to highlight the increasing chance of Western physicians encountering patients (both immigrants and expatriates/travelers) seeking help for loiasis.

Methods: We describe three cases of imported loiasis observed at two hospitals in Italy and France, and present a review of all previously published cases in the medical literature in the last 25 years (1986-2011). The search was performed using PubMed and Scopus databases using the terms "Loa loa" AND "loiasis".

Lactate detection in the brain of growth-restricted fetuses with magnetic resonance spectroscopy.

Objective: The objective of the study was to determine the feasibility of detecting fetal brain lactate, a marker of fetal metabolic acidemia, using a noninvasive technique, proton magnetic resonance spectroscopy ((1)H MRS), in intrauterine growth-restricted (IUGR) fetuses.

Study Design: In vivo human fetal brain lactate detection was determined by (1)H MRS in 5 fetuses with IUGR. Oxygenation and acid-base balance data were obtained at birth.

Cerebral maturation in IUGR and appropriate for gestational age preterm babies.

Intrauterine growth restriction (IUGR) is associated with increased risk of perinatal morbidity and mortality, as well as long-term neurological deficits. However, neurostructural correlations with observed developmental disabilities have not yet been established. Magnetic resonance imaging (MRI) could prove useful for assessing brain development in the early neonatal period.
