The absolute configuration of (+)-(E)-4-phenylbut-3-ene-2-ol.

A derivative of (+)-(E)-4-phenylbut-3-ene-2-ol is shown by X-ray crystallography to be of (R) configuration, confirming the assumption in the literature that the absolute configuration of (+)-(E)-4-phenylbut-3-ene-2-ol is (R).

Maternal hypertension and neonatal outcome among small for gestational age infants.

Objective: To determine whether maternal hypertension might improve perinatal outcome among small for gestational age (SGA) infants (< 10th percentile).

Methods: Our prospective cohort comprised 17 Canadian neonatal intensive care units (NICUs) and 3,244 SGA singletons. Multivariable regression was used to analyze the relation between maternal hypertension and each of the following: SNAP-II (Score of Neonatal Acute Physiology; ordinal regression) and neonatal survival and survival without severe intraventricular hemorrhage (logistic regression), adjusting for potential confounders.
