Substantial evidence documents the superiority of breastfeeding for mothers and breastmilk for babies. Although the American Academy of Pediatrics and the U.S. Healthy People 2010 initiative promote breastfeeding, current breastfeeding rates often fall short of recommendations. This study determined factors associated with exclusive breastfeeding 2 to 4 weeks following discharge from a large, urban, academic medical center striving for Baby-Friendly designation. Results indicated that mothers who breastfed within the first hour of birth (61%) were significantly more likely to be exclusively breastfeeding 2 to 4 weeks after discharge. Incorporating care practices that include a number of the "Ten Steps to Successful Breastfeeding," as recommended by the Baby-Friendly Hospital Initiative, may increase the duration of exclusive breastfeeding after discharge.  相似文献

We report an analysis of reading and spelling processes in a case of developmental disability associated with a genetic anomaly (Klinefelter XXXY syndrome). The results are interpreted within the framework of a model of reading and spelling development (Frith, 1985). An almost complete absence of alphabetic functions was noted. Reading appeared to be based on a ‘logographic lexicon’ (Seymour & Elder, 1986), and spelling on a letter sequence generator which was modifiable by access to a limited store of word images.  相似文献

Abstract

Venous blood pressure measurements were made by direct cannulation of the median antecubital vein. Measurements were taken at rest, during a 5-minute exercise on the bicycle ergometer, and during a 15-minute recovery period. The range of resting pressure was from 73 to 169 mm. water, with a mean pressure of 120 mm. water. The pressure during exercise increased in every case and was maintained throughout the exercise. The average increase was 118 mm. water, representing an increase of 95 percent. Venous pressure during recovery showed a very rapid drop during the first three minutes and then exhibited a progressively slower decline until a constant level was reached.  相似文献
