Study design A prospective observational study of women undergoing an amniocentesis and subsequent delivery within 72 hours. Amniotic fluid volume wa s estimated using the amniotic fluid index (AFI) and single deepest pocket techn ique and calculated by the dye-dilution technique. Results One hundred seventy -five women participated in the study. Linear regression modelling showed no si gnificant relationship between birth weight and amniotic fluid volume adjusted f or gestational age (P=.062). Similarly, there was no evidence of an association between birth weight and a dye determined amniotic fluid volume (P=.180), fixed cutoffs for the AFI (P=.224), percentiles for the AFI (P=.112), or fixed cutof fs for the single deepest pockets (P=.867). Conclusion Neonatal birth weight is not correlated with a dye-determined or ultrasound estimated amniotic fluid vol ume.展开更多

Study design In this prospective study, 185 women who were symptomatic for preterm labor were assess ed for bacterial vaginosis and fetal fibronectin. Results These women comprised 4 groups: group A (n=23 women; +bacterial vaginosis/+fetal fibronectin); group B (n=31 women; -bacterial vaginosis/+fetal fibronectin); group C (n=47 women; +bacterial vaginosis/-fetal fibronectin); and group D (n=84 women; -bacteria l vaginosis/-fetal fibronectin). The time interval from gestational age at test ing until delivery was significantly shorter for groupsAand Bversus groups C and D (P≤.05 and P<.001, respectively). Similarly, delivery at < 32 weeks of gesta tion was increased in group B (26%) compared with groups A (9%), C (2%), and D (5%; P < .009; odds ratio, 165.90; 95%CI, 30.02, 916.08). Conclusion Women w ho are symptomatic for preterm labor should be considered for fetal fibronectin and bacterial vaginosis testing.展开更多
