[Influence of maternal nutritional status, weight gain and energy intake on fetal growth in high-risk pregnancies].

Purpose: To analyze the influence of maternal nutritional status, weight gain and energy consumption on fetal growth in high-risk pregnancies.

Methods: A prospective study from August 2009 to August 2010 with the following inclusion criteria: puerperae up to the 5th postpartum day; high-risk singleton pregnancies (characterized by medical or obstetrical complications during pregnancy); live fetus at labor onset; delivery at the institution; maternal weight measured on the day of delivery, and presence of medical and/or obstetrical complications characterizing pregnancy as high-risk. Nutritional status was assessed by pregestational body mass index and body mass index in late pregnancy, and the patients were classified as: underweight, adequate, overweight and obese.

[Assessment of fetal well-being in pregnancies complicated by maternal moderate to severe thrombocytopenia].

Purpose: To analyze the results of assessment of fetal well-being in pregnancies complicated by moderate or severe maternal thrombocytopenia.

Methods: Data from April 2001 to July 2011 of 96 women with a diagnosis of thrombocytopenia in pregnancy were retrospectively analyzed. We analyzed the following tests performed during the antepartum period for fetal assessment: cardiotocography, fetal biophysical profile, amniotic fluid index and umbilical artery Doppler velocimetry.

Cardiac troponin T as a biochemical marker of cardiac dysfunction and ductus venosus Doppler velocimetry.

Objectives: The aim of this study was to determine the correlation between ductus venosus (DV) Doppler velocimetry and fetal cardiac troponin T (cTnT).

Study Design: Between March 2007 and March 2008, 89 high-risk pregnancies were prospectively studied. All patients delivered by cesarean section and the Doppler exams were performed on the same day.

Effects of maternal glycemia on fetal heart rate in pregnancies complicated by pregestational diabetes mellitus.

Objective: To investigate the influence of maternal glycemia on fetal heart rate (FHR) parameters analyzed by computerized cardiotocography in fetuses of diabetic mothers in the third trimester.

Study Design: Thirty-nine pregnant women with pregestational diabetes mellitus were studied prospectively. The inclusion criteria were a diagnosis of pregestational diabetes, singleton pregnancy between 36 and 40 weeks, and absence of fetal abnormalities.
