The monitoring of fetal weight is an important aspect of antenatal care. To construct an individually adjustable standard, we developed a model to link the predicted birth weight to a fetal weight curve which outlines how this weight is to be reached in an uncomplicated pregnancy. A formula was derived which describes the median fetal weight at each(More)
OBJECTIVE To determine the prevalence and outcome of lower urinary tract obstruction (LUTO), including the sensitivity of antenatal diagnosis. DESIGN A retrospective population-based study. SETTING Regional population-based congenital anomalies register (WMCAR). POPULATION Fetuses affected by LUTO delivered between 1995 and 2007 to women resident in(More)
Despite increasing attention and investment for maternal, neonatal, and child health, stillbirths remain invisible-not counted in the Millennium Development Goals, nor tracked by the UN, nor in the Global Burden of Disease metrics. At least 2·65 million stillbirths (uncertainty range 2·08 million to 3·79 million) were estimated worldwide in 2008 (≥1000 g(More)
OBJECTIVE To assess a technique for forward extrapolation of ultrasound-estimated fetal weight to the time of delivery. METHODS A total of 276 women who delivered within 35 days of ultrasound examination were studied. Fetal weight was estimated according to either Hadlock's formula for the biparietal diameter, abdominal circumference and femur length or(More)
Accurate assessment of fetal growth status requires the definition of an optimal standard, which represents the growth potential of the baby. Against this standard, individually 'customized' percentiles can be calculated. They improve the distinction between normal and abnormal, and help in our understanding and diagnosis of pathological fetal growth. This(More)
OBJECTIVE To analyse the biological factors affecting birthweight and to derive customized birthweight standards for a Spanish population. METHODS A retrospective cohort was created with all the singleton pregnancies delivered at term and free of pathology in our Institution. Birthweight was modeled by multiple linear regression from maternal (ethnic(More)
Stillbirth is a major obstetric complication, with 3.2 million stillbirths worldwide and 26,000 stillbirths in the United States every year. The Eunice Kennedy Shriver National Institute of Child Health and Human Development held a workshop from October 22-24, 2007, to review the pathophysiology of conditions underlying stillbirth to define causes of death.(More)
OBJECTIVE To analyze the association between maternal smoking and fetal growth restriction, defined as a failure to achieve the growth potential, and to define subgroups of higher susceptibility for this association. STUDY DESIGN A definition of growth restriction by customized birthweight standards applied to 13,661 non-malformed singleton deliveries.(More)
OBJECTIVE To derive coefficients for developing a customized growth chart for a Mid-Western US population, and to estimate the association between pregnancy outcomes and smallness for gestational age (SGA) defined by the customized growth chart compared with a population-based growth chart for the USA. METHOD A retrospective cohort study of an ultrasound(More)
OBJECTIVE To develop and test a new classification system for stillbirths to help improve understanding of the main causes and conditions associated with fetal death. DESIGN Population based cohort study. SETTING West Midlands region. SUBJECTS 2625 stillbirths from 1997 to 2003. MAIN OUTCOME MEASURES Categories of death according to conventional(More)
