OBJECTIVE To develop new gender-specific regression formulae to estimate fetal weight focusing on a particular weight range from 2,501 to 3,999 g. METHODS 3,254 singleton pregnancies were included to generate new regression formulae for female and male fetuses, and to evaluate their accuracy. RESULTS In comparison with commonly used formulae, the new gender-specific and weight-range-specifi...

The consumption of psychoactive substances during pregnancy has a negative impact on fetal growth. Heroin, methadone, and heavy alcohol consumption during pregnancy are associated with lower birth weight and central nervous system (C NS) dysfunction. Recent evidence suggests that marijuana use also may be associated with lower birth weight No information documents the impact of cocaine use on f...

BACKGROUND Worldwide, stillbirth is one of the leading causes of death. Altered fetal growth and placental abnormalities are the strongest and most prevalent known risk factors for stillbirth. The aim of this study was to identify patterns of association between placental abnormalities, fetal growth, and stillbirth. METHODS AND FINDINGS Population-based case-control study of all stillbirths a...

OBJECTIVE To apply the cumulative summation (CUSUM) technique for an evaluation of the learning process of sonographic fetal weight estimation at term in combination with the z-scores of biometry determinants and to assess the time of appearance and sources of errors. METHODS Learning curve (LC-CUSUM) and double CUSUM charts for systematic error detection based on absolute and signed mean per...

OBJECTIVE To determine the accuracy of birth weight in different birth weight (BW) groups using widely accepted formulas for fetal weight estimation (EFW). The secondary purpose was to estimate the role of examiners on the accuracy of EFW. METHODS The cross-sectional data were obtained from 5612 pregnant women. Fetal weight was estimated for each fetus using the formulas of Campbell and Wilki...

BrMedj 1989;298:1671-3 Abstract Objective-To measure the safety and efficacy of antenatal treatment with anti-D immunoglobulin. Design-Open study with historical controls. Setting-Multicentre study in 17 hospitals in West Yorkshire. Patients-1238 Rh negative women who delivered Rh positive infants after 34 weeks in their first pregnancy in 1980-1 (group 1) and 2000 similar primigravidas from 19...

In human pregnancy, reduced placental perfusion has been associated with fetal aortic thickening. However, the relative contributions of fetal undernutrition versus fetal underoxygenation to triggering alterations in fetal cardiovascular development remain uncertain. Here, we isolate the effects of chronic fetal hypoxia on fetal cardiovascular development in a specific rodent model of chronic f...

Overt hyperthyroidism is associated with miscarriage, stillbirth, preterm delivery, intrauterine growth restriction, low birth weight, preeclampsia and fetal thyroid dysfunction. Overt hypothyroidism is associated with anaemia, pregnancy-induced hypertension, preeclampsia, placental abruption, postpartum haemorrhage, premature birth, low birth weight, intrauterine fetal death, increased neonata...
