Comparison of the effects of two human milk fortifiers with different energy sources on the body composition of premature infantsKean, Penni January 2003 (has links)
Human milk fortification is recommended to meet the nutritional requirements of preterm infants. Most human milk fortifiers (HMFs) contain non-protein energy (NPE) predominantly as carbohydrate which may lead to high fat deposition relative to lean mass accretion. We hypothesized that fortifying human milk with a HMF containing NPE predominantly as fat (fatHMF) would result in a higher (1) lean mass accretion (percent lean mass) and (2) growth (anthropometry), compared to fortifying with an isocaloric, isonitrogenous HMF containing NPE predominantly as carbohydrate (carbHMF). In a double-blind randomized trial, 29 infants (≤32 weeks and appropriate for gestational age) admitted to the Neonatal Intensive Care Unit received either mother's milk fortified with the fatHMF (n = 14) or the carbHMF (n = 15). Body composition and growth measurements were performed at Baseline (at ≤10% of goal intake 150 ml/kg), Phase 1, and Phase 2 (3 weeks and 6 weeks, respectively, from starting HMF). Although neither percent lean (fat) mass nor growth were statistically different, by Phase 2 infants receiving fatHMF showed a 63% increase in percent fat mass, gained 1194 g in weight and 8.8 cm in length, whereas the carbHMF showed a 96% increase in percent fat mass, gained 1005 g in weight and 6.9 cm in length (p = 0.3586, 0.3815, and 0.1851 respectively). By Phase 2, the fatHMF infants gained 128 g in absolute dry lean tissue, whereas the carbHMF infants gained 99 g (p = 0.0362, Post hoc analysis). Differences of this magnitude are clinically important, but a larger study is required to demonstrate statistical significance.

The effects of nonnutritive sucking on state regulation in preterm infantsGoff, Dennis McKevitt January 1985 (has links)
Nonnutritive Sucking (NNS) has long been used to soothe crying infants. Systematic observations of this effect in newborn infants have revealed that NNS reduces arousal in general. Among preterm infants NNS has been used as an effective intervention in the newborn intensive care unit. However, there has been little systematic research on the immediate behavioral effects of NNS in this population of infants. The purpose of this study was to examine the effects of NNS on behavioral state in preterm infants. The results indicated that the amount of quiet sleep was increased following NNS, but that this increase was not greater than the amount of quiet sleep observed in two hours of undisturbed rest. These results are discussed in terms of intervention strategies which are designed to increase the amount of quiet sleep among preterm infants. It is suggested that a pacifier can increase the amount of quiet sleep when longer periods of uninterrupted sleep cannot be arranged. Additional results indicated that the rhythmic organization of state was more complex following NNS than during control conditions. A basic 40- to 60-minute rhythm in state was not affected by NNS. However, spectral analysis indicated that there were other faster frequency fluctuations in state. Following NNS there were more of these fluctuations and they accounted for more variance in state. This pattern is more similar to the pattern observed in low-risk newborns. These results are discussed in terms of inducing behavior patterns in preterm infants which are more similar to behavior seen in full term infants. Finally, a model is presented which suggests that the reduced arousal seen following NNS is an adjunct to an increase in parasympathetic activity. This increase in parasympathetic activity is hypothesized to be adaptive. Through this mechanism sucking is hypothesized to have a distinct behavioral effect on energy regulation in newborn infants outside of the requirements for feeding. / Ph. D.
