Mental development of preterm infants during the first year.

Developmental rates and standard scores are examined for 56 infants in 4 gestational age groups by repeated measurements on the mental scale of the Bayley Scales of Infant Development. Rates across the first year of life can be predicted largely by a biological model that assumes equality of development for infants of the same conceptual age. However, standard scores based on biological age are elevated during the early months for the most premature groups, indicating a transient advantage of increased extrauterine life. Scores from 3 to 12 months' biological age are slightly higher for the most premature groups but are consistent within groups, with no special acceleration of the premature.

Myometrial activity and plasma progesterone and oxytocin concentrations in cycling and early-pregnant ewes.

Myometrial activity and plasma progesterone (P) and oxytocin (OT) were measured in early pregnant (n = 5) and cycling (n = 5) ewes. Electromyography (EMG) leads and jugular and inferior vena cava (IVC) catheters were surgically placed in ewes about 1 wk before data collection. When ewes returned to estrus, they were bred to either an intact or vasectomized ram. Continuous EMG data were collected, and blood samples were collected twice daily from day of estrus (Day 0) until Day 18. Ewes bred with an intact ram were checked surgically for pregnancy on Day 20. Computerized, quantitative analysis of EMG events showed no difference in signal from the right to left uterine horns, and no differences between pregnant and cycling ewes (p less than 0.05) until Days 14-18 when nonpregnant ewes returned to estrus and had increased EMG activity. The mean number of EMG events 180-900 s in length decreased in pregnant ewes, but this difference was not significant (p less than 0.05). Jugular plasma progesterone (P) levels confirmed corpus luteum (CL) formation in all ewes, and no differences in P between pregnant and nonpregnant ewes were measured until Days 14-18, when cycling ewes underwent luteolysis and pregnant ewes maintained CL. IVC plasma oxytocin concentrations were increased in pregnant ewes compared to concentrations in nonpregnant ewes on Days 5-13 (p less than 0.05), and the difference was largest at Day 6 (means +/- SEM pg/ml: pregnant = 68.7 +/- 13.9, nonpregnant = 30.9 +/- 19.9).(ABSTRACT TRUNCATED AT 250 WORDS)

What can HCAs be asked to do?

Who should determine the role of health care assistants (HCAs)? If not nurses then managers may decide on the basis of cheapest is best. However, if nurses are to decide it is vital that they understand just what health care assistants can and cannot do.
