BACKGROUND: Newborns exhibit substantial variation in gestational age-adjusted and sex-adjusted fat mass proportion. The antecedent characteristics of fetal body composition that are associated with newborn fat mass proportion are poorly understood. OBJECTIVE: The aim of this study was to determine whether a composite measure of fetal fat mass is prospectively associated with newborn adiposity. METHODS: In a longitudinal study of 109 low-risk pregnancies, fetal ultrasonography was performed at approximately 12, 20 and 30 weeks gestation...

The fetal brain shows accelerated growth in the latter half of gestation, and these changes can be captured by 2D and 3D biometry measurements. The aim of this study was to quantify brain growth in normal fetuses using Magnetic Resonance Imaging (MRI) and to produce reference biometry data and a freely available centile calculator ( https://www.developingbrain.co.uk/fetalcentiles/ ). A total of 127 MRI examinations (1.5 T) of fetuses with a normal brain appearance (21-38 gestational weeks) were included in this study...

The understanding of crop domestication is dependent on tracking the original geographical distribution of wild relatives. The faba bean (Vicia faba L.) is economically important in many countries around the world; nevertheless, its origin has been debated because its ancestor could not be securely identified. Recent investigations in the site of el-Wad (Mount Carmel, Israel), provide the first and, so far, only remains of the lost ancestor of faba bean. X-ray CT scan analysis of the faba beans provides the first set of measurements of the biometry of this species before its domestication...

OBJECTIVE: Birth weight (BW) is thought to be determined by maternal health, and genetic, nutritional and placental factors; the latter being influenced by anatomical development and perfusion. Maternal cardiovascular changes contribute to uteroplacental perfusion, however they have not been investigated in relation to fetal growth/BW. Our aim was to explore the relationship between maternal cardiovascular adaptation, fetal growth and BW in healthy pregnancies. METHODS: This was a longitudinal prospective study of women planning to conceive a pregnancy...

INTRODUCTION: In the Stockholm County new guidelines for predicting the day of delivery was introduced in 2010. Recent clinical use has indicated that the predictive quality might be suboptimal. This study compares the accuracy of three equations applied during the first (crown-rump length (CRL) or bi-parietal diameter (BPD)) and second trimesters (BPD or BPD combined with femur length (FL)). MATERIAL AND METHODS: In 14,239 ultrasound exams the accuracy of estimated delivery date was compared using median deviations from actual birth date, proportion of postterms, births within +/- 7 days of estimated delivery date, accuracy variations depending on fetal size, alternative fetal measurements obtained at the same occasion, and menstrual age...

OBJECTIVE: There are limited data for counseling on and management of periviable small-for-gestational-age (SGA) fetuses. We therefore aimed to investigate the short-term outcome of periviable SGA fetuses in relation to the likely underlying cause. METHODS: This was a retrospective study of data from three London tertiary fetal medicine centers obtained between 2000 and 2015. We included viable singleton pregnancies with a severely small fetus, defined as those with an abdominal circumference ≤ 3(rd) percentile, identified between 22 + 0 and 25 + 6 weeks' gestation...
