Fetal Proinsulin and Birth Weight

Diabetic Medicine, 1994
In both diabetic and non‐diabetic pregnancies fetal insulin is an important anabolic hormone. Fetal hyperinsulinaemia is associated with accelerated fetal growth and increased birth weight. Insulin and C‐peptide concentrations in both umbilical cord and amniotic fluid reflect fetal β‐cell secretion and are correlated with birth weight.

Fetal weight/placental weight ratio and perinatal outcome

American Journal of Obstetrics and Gynecology, 1984
The relationship of placental size to perinatal outcome was investigated in a population of low-risk infants. A trimmed and drained placenta was weighed for each of 417 low-risk infants, and for 108 infants whose intrapartum course was complicated only by compression of the umbilical cord.

Variation in Fetal Weight Percentile Estimates

Journal of Ultrasound in Medicine, 2022
ObjectivesWeight percentiles are generally reported without any indication of error. This variation can lead a fetus being mistakenly classified erroneously as having intrauterine growth restriction (IUGR) or macrosomia. The goal of this study was to compare estimated weight percentiles with the actual observed weight percentile for each gestational ...

Use of the fetal chest in estimating fetal weight

American Journal of Obstetrics and Gynecology, 1992
This study was designed to develop formulas using the chest circumference instead of the abdominal circumference for estimating fetal weight.Ultrasonographic measurements of the chest circumference, biparietal diameter, abdominal circumference, humeral length, and femoral length were obtained in 75 term fetuses of uncomplicated pregnancies within 24 ...

The effect of maternal obesity on sonographic fetal weight estimation and perinatal outcome in pregnancies complicated by fetal growth restriction

Journal of Clinical Ultrasound, 2016
Maternal obesity represents a challenge in the sonographic (US) assessment of fetal weight, and is a recognized risk factor for adverse pregnancy outcome.

Accurate Ultrasonic Estimation of Fetal Weight

American Journal of Perinatology, 1985
The accuracy of eight ultrasonic fetal weight formulas were analyzed in 1099 fetuses who underwent real-time ultrasound examination within 72 hours prior to delivery. Shepard's formula was most consistently found to give the lowest systematic and random errors throughout all weight categories, though Deter's formula had an almost identical accuracy ...

Fetal weight and membrane tensile strength

American Journal of Obstetrics and Gynecology, 1964
Abstract 1. 1. The tensile strength per unit width of membranes was studied in 62 cases of premature delivery and late abortion, 27 cases of premature rupture of the membranes, and 101 normal term deliveries. 2. 2. The average tensile strength of the membranes from normal term deliveries was 0.207 Kg.

Fetal weight estimation in twin pregnancies

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1989
In this study the fetal weight was estimated by ultrasound measurements of the biparietal (BPD) and abdominal diameters (AD) in 154 consecutive twin pregnancies. In 80 twins an attempt to estimate fetal weight was made 0-4 days before delivery (26% of all twins examined).
