Poor fetal growth is an important cause of perinatal mortality and morbidity. Based on the hypothesis that early diagnosis of fetal growth problems leads to more appropriate management and therefore, improved outcome, a randomized controlled trial of ultrasound measurement was performed on 1,528 women booked through a hospital antenatal clinic. This compared a number of perinatal outcomes between the group who had a routine 2-stage examination (early dating and 34-week scan) and a group who had only a dating scan and then additional scans as generated by their clinical situations. No significant differences could be found between the groups when these perinatal outcomes were considered. These results mirror previously published randomized controlled trials. Selection of women for third trimester ultrasound examination for suspected fetal growth problems should be based on careful clinical assessment and should not be routine. In a randomized prospective study, performed on 45 pregnancies with clinical and sonographic suspicion for intrauterine fetal growth retardation, examinations were done to evaluate the therapeutic effect of bed rest and of additional daily administered glucose infusions or oral galactose applications respectively on the fetal growth, the hemodynamic, respiratory and endocrine insufficiency of the materno-feto-placental unit as well as selected biochemical parameters of the umbilical blood. There is no positive therapeutic effect, either on the impaired endocrine partial function nor on the reduced respiratory function of the feto-placental unit. It is obvious, that despite the improvement of the nutritional supply of the fetus and the revival of the regular fetal growth, the previous lack of fetal growth can not be altered. This can be demonstrated in all three therapeutic groups due to the fact of a resulting high hypotrophy-rate of the newborns. The results prove that the additional supply of the fetus with glucose or galactose does not remarkably improve the therapeutic effectivity as opposed by strict bed rest alone. A prospective study was made to evaluate whether bedrest in hospital is beneficial in pregnancies where intra-uterine growth retardation (IUGR) was suspected. Diagnosis was based on routine fetometry at 32 weeks of gestation, in conjunction with general ultrasound screening. 107 patients with suspected IUGR-pregnancies were divided into two groups, 49 in a hospital bedrest group and 58 in an 'out-patient' group. Fifteen women in the bedrest group refused hospitalization, and 8 women in the out-patient group had to be hospitalized for medical reasons other than suspected growth retardation, leaving 79% of the women in their allocated group. The women in the bedrest group were hospitalized for a mean duration of 29.2 days (range 5-54). The results suggest that bedrest in hospital is not beneficial, either to fetal growth or to pregnancy outcome. This study examined whether voucher-based reinforcement therapy (VBRT) contingent upon smoking abstinence during pregnancy is an effective method for decreasing maternal smoking during pregnancy and improving fetal growth.
                A two-condition, parallel-groups, randomized controlled trial was conducted in a university-based research clinic. A total of 82 smokers entering prenatal care participated in the trial.
                Participants were assigned randomly to either contingent or non-contingent voucher conditions. Vouchers exchangeable for retail items were available during pregnancy and for 12 weeks postpartum. In the contingent condition, vouchers were earned for biochemically verified smoking abstinence; in the non-contingent condition, vouchers were earned independent of smoking status.
                Smoking outcomes were evaluated using urine-toxicology testing and self-report. Fetal growth outcomes were evaluated using serial ultrasound examinations performed during the third trimester.
                Contingent vouchers significantly increased point-prevalence abstinence at the end-of-pregnancy (41% versus 10%) and at the 12-week postpartum assessment (24% versus 3%). Serial ultrasound examinations indicated significantly greater growth in terms of estimated fetal weight, femur length and abdominal circumference in the contingent compared to the non-contingent conditions.
                These results provide further evidence that VBRT has a substantive contribution to make to efforts to decrease maternal smoking during pregnancy and provide new evidence of positive effects on fetal health. Thirty-five children with cerebral palsy and moderate eating impairment were studied to determine the effect of oral sensorimotor treatment (OST) on eating efficiency and measures of growth (weight gain). After taking effects of maturation into account, 11 children who received OST (group A) exceeded their expected centile line by 1.7 percentile points after 10 weeks of treatment. Chewing exercises alone (group B) had no effect on weight gain. Although small decreases occurred in the time needed to eat three standard textures of food (solid, viscous, puree) in groups A and B, these were not significant. Children maintained their weight-for-age percentile line although at the lower end of expected norms. These children will be at risk of growth failure because of the increased energy demands once they enter their teenage growth spurt. The clinical implications of these findings are that prolonged mealtime and oral-motor therapies may be adequate through the childhood years. Thereafter, children's growth must be monitored carefully, and oral caloric supplementation is suggested to provide the necessary energy for growth. Early fetal biparietal diameter (BPD) measurements were obtained with ultrasound in 1062 women attending for antenatal care; a random half had the results withheld from the obstetricians. Of the 1026 women who were sure of the dates of their last normal menstrual period, 829 (81%) were found to have appropriate biparietal diameter measurements, in 3% the pregnancy was more than 2 weeks further advanced and in 14% more than 2 weeks less than calculated. In 30% of the women whose results were intended to be withheld, the code had to be broken because of clinical concern. There were no differences in fetal outcome (birthweight centile, Apgar score at 1 min and perinatal mortality) in the women whose BPD results were known compared with those whose results were withheld from the obstetrician. But a significantly larger number of labours were induced for suspected growth retardation when the gestational age was known. A randomized clinical trial was performed to test the hypothesis that if suspected intrauterine growth retardation (IUGR) is associated with normal umbilical artery Doppler ultrasound findings, hospitalization can safely be avoided. One hundred and fifty women with singleton pregnancies and suspected IUGR were randomized between an intervention (n = 74) and a control group (n = 76). In the intervention group, clinicians were strongly requested not to hospitalize for suspected IUGR if the Doppler findings were normal. In the control group, the Doppler results were not revealed and the participants received the standard management for suspected IUGR. Endpoints of the trial were: costs in terms of hospitalization, perinatal outcome, neurological development, and postnatal growth. Duration of hospitalization was significantly shorter in the intervention group than in the control group. Contrary to expectations, the hospitalization rate during pregnancy in the intervention group was not below that of the control group. This negative finding was partly due to the admission of patients in the intervention group despite their normal Doppler results. Moreover, the trial might have induced a more critical attitude towards hospitalization in suspected IUGR, decreasing admission in the control group. No clear differences were found in perinatal outcome, neurological development, or postnatal growth. The results suggest that normal umbilical artery Doppler findings in suspected cases of IUGR justify outpatient management. At hospital discharge, preterm infants may have low body stores of nutrients, deficient bone mineralization, and an accumulated energy deficit. This double-blind, randomized study evaluated the growth of premature infants with birth weights <1800 g who were fed a 22 kcal/fl oz nutrient-enriched postdischarge formula (PDF) or a 20 kcal/fl oz term-infant formula (TF) from hospital discharge to 12 months' corrected age (CA).
                Infants were randomized to PDF or TF a few days before hospital discharge with stratification by gender and birth weight (<1250 g or >/=1250 g). The formulas were fed to 12 months' CA. Growth was evaluated using analysis of variance controlling for site, feeding, gender, and birth weight group. Interaction effects were also assessed. Secondary analyses included a repeated measures analysis and growth modeling.
                One hundred twenty-five infants were randomized; 74 completed to 6 months' CA and 53 to 12 months' CA. PDF-fed infants weighed more than TF-fed infants at 1 and 2 months' CA, gained more weight from study day 1 to 1 and 2 months' CA, and were longer at 3 months' CA. There were significant interactions between feeding and birth weight group-among infants with birth weights <1250 g, those fed PDF weighed more at 6 months' CA, were longer at 6 months' CA, had larger head circumferences at term 1, 3, 6, and 12 months' CA, and gained more in head circumference from study day 1 to term and to 1 month CA. The repeated measures and growth modeling analyses confirmed the analysis of variance results. The PDF formula seemed to be of particular benefit for the growth of male infants. Infants fed the PDF consumed less formula and had higher protein intakes at several time points. Energy intakes, however, were not different.
                Growth was improved in preterm infants fed a nutrient-enriched postdischarge formula after hospital discharge to 12 months' CA. Beneficial effects were most evident among infants with birth weights <1250 g, particularly for head circumference measurements. Our objectives were 1) to determine whether moderate nutrient supplementation of mother's milk (MM) for preterm infants, in the form of a new multinutrient fortifier (MNF), would improve short-term growth and bone mineral content (BMC) when compared with supplementation with calcium and phosphorus alone; and 2) to investigate whether moderate calcium and phosphorus intakes, in the form of calcium glycerophosphate (CaGP), resulted in a BMC similar to that of term corrected infants. Twenty-five preterm infants fed MM were randomly assigned to receive either MM+MNF or MM+CaGP. A third group of infants fed preterm formula (PTF) served as a comparison group. Whole-body BMC and lean and fat mass were determined by dual-energy X-ray absorptiometry (DXA) at full-term age. Nitrogen retention and calcium, phosphorus, and zinc intakes were determined by using mass balance techniques. Nitrogen retention was significantly lower in the MM+CaGP group than in the PTF group as were both weight and length gain (weight gain: 16.6 +/- 1.6, 14.2 +/- 2.0, and 16.1 +/- 2.9 g x kg(-1) x d(-1); length gain: 1.1 +/- 0.2, 0.9 +/- 0.2, and 1.1 +/- 0.3 cm/wk for the MM+MNF, MM+CaGP, and PTF groups, respectively). Biochemical indexes of mineral status and bone turnover were normal. Conservative amounts of calcium and phosphorus, as CaGP, resulted in adequate BMC. Moderate amounts of protein, calcium, and phosphorus plus trace elements added to MM in the form of an MNF resulted in improved linear growth but did not provide any advantages to BMC when compared with supplementation with calcium and phosphorus alone. To test whether a policy of hospitalization for bed rest, from 28-30 weeks gestation until delivery, lengthens the duration of gestation, improves fetal growth and decreases neonatal morbidity in twin pregnancy.
                A randomized controlled trial.
                Harare Maternity Hospital, Zimbabwe.
                118 women with an uncomplicated twin pregnancy between 28 and 30 weeks gestation.
                Hospitalization for bed rest. Encouraged to rest in bed as much as possible, although voluntary ambulation was allowed.
                Gestational age at delivery and number of infants delivered preterm (less than 37 weeks); birthweight and number of small-for-gestational age (SGA) infants; neonatal morbidity was assessed by number of infants requiring admission to the neonatal unit and the length of stay.
                There was no effect on duration of gestation or the occurrence of preterm delivery. Mean birthweight was greater in the hospitalized group (t = -2.28, df 234, P = 0.02) and there were fewer SGA infants (OR 0.57, 95% CI 0.33-0.96). No differences were found in neonatal morbidity.
                Hospitalization for bed rest does not prolong pregnancy but can improve fetal growth, although this was not reflected in improved neonatal morbidity. Whether twin fetal growth can be enhanced similarly in other populations should be investigated. Although induction of labor in women with prior cesareans is controversial, we compared misoprostol to oxytocin in such women in a randomized trial. The investigation was terminated prematurely because of safety concerns.
                Disruption of the prior uterine incision was found in two of 17 misoprostol-treated women. The first woman underwent repeat cesarean delivery at 42 weeks because of fetal tachycardia and repetitive late decelerations. A 10-cm vertical rent in the anterior myometrium was discovered. The second woman underwent induction for fetal growth restriction. Loss of fetal heart tones and abnormal abdominal contour prompted emergent cesarean for suspected uterine rupture. An 8-cm longitudinal uterine defect was found.
                When misoprostol is used in women with previous cesareans, there is a high frequency of disruption of prior uterine incisions.
There is not enough evidence to evaluate the use of nutrient therapy for suspected impaired fetal growth. The studies were too small to assess clinical outcomes adequately.
