OBJECTIVES To present the fetal measurements in relation to the foot length at 10-16 weeks gestation on antenatal ultrasound. MATERIALS AND METHODS We reviewed the fetal measurements in 47 scans performed at 10-16 weeks gestation in women attending routine antenatal care. The fetal measurements and measurement ratios were examined in relation to the foot length. RESULTS The fetal biparietal...

This paper investigates the effects of mother’s age and parity on the prenatal allocation of resources in sons and daughters using a sample of 6994 in 20to 34-year-old mothers from Granada (Spain). This study tests the Trivers– Willard allocation model, which predicts that, depending on the mother’s condition, there can be a bias from 50/50 expected investment in the sexes. The results show tha...

Introduction The current study evaluated the effect of obesity on neonatal respiratory distress syndrome (RDS) in pregnant women who were administered ACSs due to risk preterm birth and delivered before 34 weeks gestation. Material methods In this retrospective study, 414 had a singleton pregnancy, aged 18–40 years, received two doses ACS 24 h apart between 23+0/7 33+5/7 gestation included. For...

BACKGROUND Cerebral palsy seems to be more common in term babies whose birthweight is low for their gestational age at delivery, but past analyses have been hampered by small datasets and Z-score calculation methods. METHODS We compared data from ten European registers for 4503 singleton children with cerebral palsy born between 1976 and 1990 with the number of births in each study population...

Two experiments were conducted, involving 68 third-litter sows and 20 first-litter gilts in Exp. 1 and 82 first-litter gilts in Exp. 2. On d 108 of gestation, the dams were moved into individual crates, stratified by parity and breed, and randomly assigned within strata, to one of two treatments: (1) fed a basal 16% protein corn-soybean meal diet, 1.8 and 2.7 kg once daily before farrowing and ...

Objective To determine whether exposure to any antenatal corticosteroids is associated with a lower rate of death at each gestational age at which administration is currently recommended.Design Prospective cohort study.Settings 300 participating neonatal intensive care units of the Pediatrix Medical Group in the United States.Participants 117 941 infants 23 0/7 to 34 6/7 weeks' gestational age ...

One-hundred and eleven Doppler echocardiographic examinations were performed on 88 normal fetuses, ranging from 16 to 41 weeks of gestation. Aortic and pulmonary maximal velocity (MV), acceleration time (AT), ejection time (ET), MV/AT (acceleration velocity: AV) and AT/ET ratio in systole were assessed on each blood flow velocity waveform. Aortic MV and pulmonary MV correlated well with gestati...

Pregnancy is a complex state in woman's life. It associated with anatomical and physiologic changes that greatly affect not only the mother but living fetus inside her womb. This case of 22-year-old woman at 36 5/7 weeks age gestation presented intractable tachycardia. The patient emergency room cardiorespiratory distress conjunction preterm labor.

Dexamethasone is frequently administered to the developing fetus to accelerate pulmonary development. The purpose of the present study was to determine if prenatal dexamethasone programmed a progressive increase in blood pressure and renal injury in rats. Pregnant rats were given either vehicle or 2 daily intraperitoneal injections of dexamethasone (0.2 mg/kg body weight) on gestational days 11...

PURPOSE to describe alcohol and tobacco use in adult pregnant women and determine its association with the obstetric outcome. METHODS analytical transversal study, in which 433 adult pregnant women and their newborns have been included, attended at a public maternity hospital in Rio de Janeiro, from 1999 to 2006. Information on the mother and the newborn was collected at the moment of deliver...
