Maternal cocaine use and infant behavior.

We hypothesized that prenatal cocaine exposure results in less optimal infant behavior and more impaired maternal-infant interaction in healthy term infants. Infants were evaluated with the Neonatal Behavioral Assessment Scale (NBAS) at days 1-3 and 11-30 of age, and mother-infant pairs with the Nursing Child Assessment of Feeding Scale (NCAFS) at 7-16 weeks of age. Drug use was determined from confidential interviews, urine assays and medical records. Cocaine-exposed infants (N = 51) were no different than unexposed comparison infants (N = 60) on the first NBAS exam. On the second NBAS exam, 20 cocaine-exposed infants had slightly lower motor cluster scores compared with those of 32 unexposed infants (p = 0.01), but this difference was reduced after control for several confounding variables. The NCAFS detected no differences between groups in maternal or infant behavior. Infants in this population showed no clinically meaningful effects of cocaine exposure on behavior or maternal-infant interaction.

Identification of common functional configurations among molecules.

A new algorithm for identifying three-dimensional configurations of chemical features common to a set of molecules is described. The algorithm scores each configuration based both on the degree to which it is common to the input set and its estimated rarity. The algorithm can be applied to molecules with large (several hundred) conformational models. Results from the application of this algorithm to three data sets are discussed: PAF antagonists, HIV reverse transcriptase inhibitors, and HIV protease inhibitors. Of particular interest is a common configuration identified for a set of HIV reverse transcriptase inhibitors; this configuration is shared by two new, potent inhibitors that were recently described in the literature.
