Serum samples were obtained from 21 normal human fetuses after therapeutic abortion for psychiatric indications. Fetal crown-rump length ranged from 5.2 to 22.5 cm, corresponding to the gestational age of 65-168 days.Serum thyroxine, assayed by a modification of the Murphy-Pattee method, was identified in the second smallest fetus examined at 78 days gestation. Thereafter it increased rapidly, ...
Background: The purpose of this study was to compare electronic fetal heart rate monitoring (EFM) characteristics between Appropriate for Gestational Age (AGA ) and Small for Gestational Age (SGA) fetuses and to determine whether SGA fetuses have specific abnormalities. Materials and Methods: Among children born from Apr 2002 to Mar 2003 in Arash hospital, we identified 300 singleton infants b...
Gestational age is highly correlated with birth outcomes including birthweight and infant mortality. Since gestational age is not recorded at the registration of live births in England and Wales, it has not been possible to produce routine statistics on gestation-specific infant mortality rates. A new system, introduced in 2002, for allocating NHS numbers at birth (NN4B) provided the opportunit...
OBJECTIVE To determine coital incidence at term and to estimate its effect on labor onset and mode of delivery. METHODS Healthy women with uncomplicated pregnancies and established gestational age were recruited to keep a diary of coital activity from 36 weeks of gestation until birth and to answer a short questionnaire. Two hundred women with complete coital diaries were available for analys...
OBJECTIVES This report presents 2005 fetal and perinatal mortality data by a variety of characteristics, including maternal age, marital status, race, Hispanic origin, and state of residence; and by fetal gestational age at delivery, birthweight, plurality, and sex. Trends in fetal and perinatal mortality are also examined. METHODS Descriptive tabulations of data are presented and interpreted...
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 & Aims : At least two third of neonatal morbidity and mortality are due to preterm labor. Transvaginalultrasonography has an important role in diagnosis of cervical incompetency and prediction of preterm labor. T he aim of this study was to determine the value of ultrasonographically measured cervical length between 16-24 weeks gestation in the prediction of spontaneous preterm d...
BACKGROUND Late-onset preeclampsia is the most prevalent phenotype of this syndrome; nevertheless, only a few biomarkers for its early diagnosis have been reported. We sought to correct this deficiency using a high through-put proteomic platform. METHODS A case-control longitudinal study was conducted, including 90 patients with normal pregnancies and 76 patients with late-onset preeclampsia ...
CONTEXT Current guidelines, initially published in 1995, recommend antenatal corticosteroids for mothers with preterm labor from 24 to 34 weeks' gestational age, but not before 24 weeks due to lack of data. However, many infants born before 24 weeks' gestation are provided intensive care. OBJECTIVE To determine if use of antenatal corticosteroids is associated with improvement in major outcom...
Few criteria exist for identifying which babies merit special nursing care, and many asymptomatic babies are offered such care unnecessarily. Birth weight is usually used to identify babies in need of special care at birth, but gestational age is a better discriminator. Babies of more than 35 weeks' gestation do not normally require admission to a special care nursery. Those preterm babies who ...
