a prospective study of 550 consecutive mothers delivered in amin ob. gyn center of isfahan university was performed to determine the relationships between maternal anemia, placental weight and neonatal birth weight. the important findings were marked placental hypertrophy in anemic mothers. (r= -/9.95) .it is probable that in anemic mothers placental hypertrophy is a compensatory mechanism resp...

placenta plays a vital role in normal fetal development and failure of placenta to gain weight and insufficiency of its function can result in fetal disorders. we performed this study to determine placental weight and factors associated with low weight placentas. in a longitudinal cross-sectional study, women with single pregnancy, and gestational age between 37-42 weeks were studied. the subje...

OBJECTIVE This study aimed to evaluate the placental weight, volume, and density, and investigate the significance of placental ratios in pregnancies complicated by small for gestational age (SGA), preeclampsia (PE), and gestational diabetes mellitus (GDM). METHODS Two hundred and fifty-four pregnant women were enrolled from August 2005 through July 2013. Participants were divided into four g...

OBJECTIVE: The aim of the present study was to compare the placental weight and birth weight/placental weight ratio for intrauterine growth-restricted and non-intrauterine growth-restricted monochorionic and dichorionic twins. METHODS: This was a retrospective analysis of placentas from twin pregnancies. Placental weight and the birth weight/placental weight ratio were compared in intrauterin...

INTRODUCTION Maternal nutritional and metabolic factors influence the developmental environment of the fetus. Virtually any nutritional factor in the maternal blood has to pass the placental membranes to reach the fetal blood. Placental weight is a commonly used measure to summarize placental growth and function. Placental weight is an independent determinant of fetal growth and birthweight and...

Foaling data from 348 Thoroughbred foals born on a commercial stud were analysed to investigate interrelationships among mare age, parity, gestation length, foal sex, placental weight, and foal birth weight. Placental weight was positively correlated with foal birth weight up to a threshold of 6.5 kg; above this, placental weight was not significantly associated with foal birth weight. Placenta...

BACKGROUND Pregnancies conceived by assisted reproductive technology (ART) are at increased risk of adverse outcomes. Previous studies have suggested increased placental weight and increased placental weight/birthweight ratio in pregnancies associated with adverse outcomes. We therefore studied the association of ART with placental weight and placental weight/birthweight ratio. METHODS We inc...

Background: Although routine measurements are taken at birth, the derivable benefits from their interpretations have not been maximized in care of newborn. 
 Aim: To determine relationship between placental weight (PW) maternal biosocial characteristics, birth (BW) and placental-to-birth-weight ratio (PBWR) on immediate follow up newborn.
 Methods: A cross-sectional study involving pa...

BACKGROUND Previous studies of maternal risk factors for abnormal placental growth have focused on placental weight and placental ratio as measures of placental growth. We sought to identify maternal risk factors for placental weight and two neglected dimensions of placental growth: placental thickness and chorionic plate area. METHODS We conducted an analysis of 24,135 mother-placenta pairs ...
