22. Fetal measurements

Evans, did bring some changes to recommendations,most particularly that dating after 13 weeks be based on head circumference measurement rather than bi-parietal diameter. The revised guidance was published in February 2007, and was widely welcomed. However, it was not long before problems arose with the crown rump length formula. Whilst the formula recommended was in keeping with that used in many obstetric ultrasound units, it quickly became apparent that the BMUS formula was not the same (...)

23. Fetal head circumference, operative delivery, and fetal outcomes: a multi-ethnic population-based cohort study. Full Text available with Trip Pro

Fetal head circumference, operative delivery, and fetal outcomes: a multi-ethnic population-based cohort study. Operative delivery procedures, such as primary cesarean section, vacuum-assisted, and forceps-assisted vaginal delivery increase maternal and fetal morbidity, and the cost of care. We evaluated whether large fetal head circumference (FHC) independently increases risk of such interventions, as well as fetal distress or low Apgar score, in anatomically normal infants.We conducted (...) a population-based retrospective cohort study using Washington State birth certificate data. We included singleton, term infants born to nulliparous mothers from 2003-2009. We compared mode of delivery and fetal outcomes in 10,750 large-FHC (37-41 cm) infants relative to 10,750 average-FHC (34 cm) infants, frequency matched by birth-year.Large-FHC infants were nearly twice as likely to be delivered by primary cesarean section as average-FHC infants (unadjusted relative risk [RR] 1.84, 95% confidence

bank designed specific for US fetal head structure. Both shape- and anatomic-based features calculated from the segmented head region are then fed into a random forest classifier to determine the quality of the image (e.g., whether the image is acquired from a correct imaging plane), from which fetal head measurements [biparietal diameter (BPD), occipital-frontal diameter (OFD), and head circumference (HC)] are derived. The experimental results show a good performance of our method for US quality (...) Automatic image quality assessment and measurement of fetal head in two-dimensional ultrasound image Owing to the inconsistent image quality existing in routine obstetric ultrasound (US) scans that leads to a large intraobserver and interobserver variability, the aim of this study is to develop a quality-assured, fully automated US fetal head measurement system. A texton-based fetal head segmentation is used as a prerequisite step to obtain the head region. Textons are calculated using a filter

Three-dimensional ultrasound imaging of fetal brain fissures in the growth restricted fetus. To examine differences in growth trajectories of fetal brain fissures in the growth restricted fetus (FGR) compared to controls.We selected a subgroup of 227 women with a singleton pregnancy from the Rotterdam Periconceptional Cohort. Participants received three-dimensional ultrasound (3D-US) examinations of the fetal brain at 22, 26 and 32 weeks of gestational age (GA). The left and right Sylvian (...) to controls, the trajectory of the right Sylvian fissure depth was significantly decreased (ß = -4.30, 95%CI = -8.03;-0.56, p = 0.024) while its growth rate was slightly increased (ß = 0.02, 95%CI = 0.00;0.04, p = 0.04), after adjustment for GA, head circumference, gender, educational level and parity.The small differences in brain fissure measurements between 22 and 32 weeks GA in FGR warrant further investigation in larger cohorts with postnatal follow-up.

) is a population-based project that assessed fetal growth and newborn size in eight geographically defined urban populations. These groups were selected because most of the health and nutrition needs of mothers were met, adequate antenatal care was provided, and there were no major environmental constraints on growth. As part of the Newborn Cross-Sectional Study (NCSS), a component of INTERGROWTH-21(st) Project, we measured weight, length, and head circumference in all newborn infants, in addition (...) International standards for newborn weight, length, and head circumference by gestational age and sex: the Newborn Cross-Sectional Study of the INTERGROWTH-21st Project. In 2006, WHO published international growth standards for children younger than 5 years, which are now accepted worldwide. In the INTERGROWTH-21(st) Project, our aim was to complement them by developing international standards for fetuses, newborn infants, and the postnatal growth period of preterm infants.INTERGROWTH-21(st

29. Relationships between Head Circumference, Brain Volume and Cognition in Children with Prenatal Alcohol Exposure Full Text available with Trip Pro

Relationships between Head Circumference, Brain Volume and Cognition in Children with Prenatal Alcohol Exposure Head circumference is used together with other measures as a proxy for central nervous system damage in the diagnosis of fetal alcohol spectrum disorders, yet the relationship between head circumference and brain volume has not been investigated in this population. The objective of this study is to characterize the relationship between head circumference, brain volume and cognitive (...) performance in a large sample of children with prenatal alcohol exposure (n = 144) and healthy controls (n = 145), aged 5-19 years. All participants underwent magnetic resonance imaging to yield brain volumes and head circumference, normalized to control for age and sex. Mean head circumference, brain volume, and cognitive scores were significantly reduced in the prenatal alcohol exposure group relative to controls, albeit with considerable overlap between groups. Males with prenatal alcohol exposure had

Pre-conception and prenatal alcohol exposure from mothers and fathers drinking and head circumference: results from the Norwegian Mother-Child Study (MoBa) Although microcephaly is a feature of Fetal Alcohol Syndrome, it is currently unknown whether low-to-moderate prenatal alcohol exposure affects head circumference. Small magnitude associations reported in observational studies are likely to be misleading due to confounding and misclassification biases. Alternative analytical approaches (...) such as the use of family negative controls (e.g. comparing the effects of maternal and paternal exposure) could help disentangle causal effects. We investigated the association of maternal and paternal alcohol drinking before and early in pregnancy with infant head circumference, using data from 68,244 mother-father-offspring trios from the Norwegian Mother and Child Cohort Study (MoBa) (1999-2009). In analyses adjusted for potential confounders, we found no consistent pattern of association between maternal

31. Dietary change mediates relationships between stress during pregnancy and infant head circumference measures: the QF2011 study. (Abstract)

Dietary change mediates relationships between stress during pregnancy and infant head circumference measures: the QF2011 study. Prenatal maternal stress can adversely affect birth outcomes, likely reflecting effects of maternal stress hormones on fetal development. Maternal stress might also induce behavioural changes, such as dietary change, that might influence fetal development. Few studies have documented relationships between stress and dietary change in pregnancy. We analysed stress (...) and dietary change among 222 pregnant women exposed to the 2011 Queensland Floods. We assessed women's objective hardship, subjective distress and cognitive appraisal of the disaster; changes in their diets and their associations with infants' gestational age, weight, length and head circumference at birth, head circumference to birth length ratio (HC/BL) and ponderal index. Greater objective hardship was correlated with more negative dietary change, skipped meals and skipped multivitamins. There were

A large head circumference is more strongly associated with unplanned cesarean or instrumental delivery and neonatal complications than a high birth weight. Fetal size impacts on perinatal outcomes. We queried whether the fetal head, as the fetal part interfacing with the birth canal, might impact on obstetric outcomes more than birthweight (BW). We examined associations between neonatal head circumference (HC) and delivery mode and risk of perinatal complications as compared to high BW.This (...) was an electronic medical records-based study of term singleton births (37-42 weeks' gestation) from January 2010 through December 2012 (N = 24,780, 6343 primiparae).
