Amniotic fluid was collected through an intrauterine catheter from 52 women with clinical intraamniotic infection and from 52 uninfected matched control women. The amniotic fluid was cultured quantitatively for anaerobes and aerobes. Patients with intraamniotic infection were matched with the control women on the basis of gestational age, interval from membrane rupture to specimen collection, and interval from membrane rupture to delivery. The patients with intraamniotic infection had a significantly higher mean temperature (38.4 vs. 37.1 C) and a higher mean leukocyte count (15,740 vs. 11,740 cells/mm3). In 80.6% of specimens from the women with intraamniotic infection and 30.8% of those from the control subjects, greater than or equal to 10(2) colony-forming units (cfu)/ml were isolated from the amniotic fluid (P less than 0.001). Also, in 69.2% of the former and 7.7% of the latter, there were greater than or equal to 10(2) cfu of isolates considered to be "high-virulence" isolates/ml (P less than 0.001).

DHA supplementation of infant formula at 0.32% of total fatty acids improves visual acuity. Higher amounts of DHA supplementation were not associated with additional improvement of visual acuity. This trial was registered at clinicaltrials.gov as NCT00753818.

Results from this clinical trial demonstrate that long-chain polyunsaturated fatty acid supplementation of formula in term infants produces blood lipid fatty acid profiles that are similar to those observed in breast-fed infants. This supplementation leads to better visual function later in life (i.e., 1 year of age) than that shown by infants fed commercial formula.

LCP supplementation of term infant formula during the first year of life yields clear differences in visual function and in total red blood cell lipid composition.

The results suggest that the critical period during which the dietary supply of LCPs can influence the maturation of cortical function extends beyond 6 wk of age.
