Background: Necrotizing enterocolitis (NEC) is a frequent cause of mortality and morbidity in very low birth weight (VLBW) infants. Human milk (HM) feeding has been associated with lower risk of NEC. However, mothers of VLBW infants often experience insufficient milk production, resulting in mixed feedings of HM and formula. Moreover, medical complications often limit the volume of feeding they can be given.Objective: To determine if high proportions of (50% or greater) HM enteral feeding within the first 14 days of life are protective against NEC.Method: This was a prospective cohort study of VLBW infants who were grouped according to the HM proportion of enteral feeding in the first 14 days: <50% (low human milk, LHM, n ¼ 46) and X50% (high human milk, HHM, n ¼ 156). The outcome of interest was development of NEC (Bell stage 2 or 3). Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) and to assess potential confounding due to perinatal risk factors.Result: Two hundred and two infants were studied. Confirmed NEC occurred in 5/46 (10.6%) of the LHM group, as compared with 5/156 (3.2%) of the HHM. Gestational age was the only perinatal factor associated with risk of NEC. After adjustment for gestational age, HHM was associated with a lower risk of NEC ((OR ¼ 0.17, 95% CI: 0.04 to 0.68), P ¼ 0.01). Conclusion:Enteral feeding containing at least 50% HM in the first 14 days of life was associated with a sixfold decrease in the odds of NEC.
A 42-day tapering course of dexamethasone was associated with an increased risk of cerebral palsy. Possible explanations include an adverse effect of this therapy on brain development and/or improved survival of infants who either already have neurologic injury or who are at increased risk for such injury.
Objectives To compare 18- to 22-month cognitive scores and neurodevelopmental impairment (NDI) in 2 time periods using the National Institute of Child Health and Human Development’s Neonatal Research Network assessment of extremely low birth weight infants with the Bayley Scales of Infant Development, Second Edition (Bayley II) in 2006–2007 (period 1) and using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley III), with separate cognitive and language scores, in 2008–2011 (period 2). Study design Scores were compared with bivariate analysis, and regression analyses were run to identify differences in NDI rates. Results Mean Bayley III cognitive scores were 11 points higher than mean Bayley II cognitive scores. The NDI rate was reduced by 70% (from 43% in period 1 to 13% in period 2; P < .0001). Multivariate analyses revealed that Bayley III contributed to a decreased risk of NDI by 5 definitions: cognitive score <70 and <85, cognitive or language score <70; cognitive or motor score <70, and cognitive, language, or motor score <70 (P < .001). Conclusion Whether the Bayley III is overestimating cognitive performance or whether it is a more valid assessment of emerging cognitive skills than the Bayley II is uncertain. Because the Bayley III identifies significantly fewer children with disability, it is recommended that all extremely low birth weight infants be offered early intervention services at the time of discharge from the neonatal intensive care unit, and that Bayley scores be interpreted with caution.
OBJECTIVE. Although it is well documented that breastfeeding promotes health and development of very low birth weight (VLBW) infants, lactation initiation among mothers of VLBW infants is low. Mothers are anxious about the health of their children, and medical staff may be reluctant to promote breastfeeding out of concern for increasing that anxiety. Therefore, the purpose of this study was to examine whether mothers of VLBW infants who initially planned to formula feed were different in terms of their level of anxiety and maternal stress compared with mothers who had planned to breastfeed their infants. The aims of this study were to (1) determine whether counseling mothers of VLBW infants who had initially planned to formula feed on the benefits of breast milk would increase their stress and anxiety levels, (2) assess whether mothers who initially had not planned to breastfeed changed their plans after counseling to provide breast milk, and (3) measure the amount of breast milk expressed by mothers who initially planned to formula feed. Their results were compared with those of mothers of VLBW infants who initially planned to breastfeed. METHODS. Initial plan to breastfeed (initial breastfeed group [IBG]; n = 115) or formula feed (initial formula feed group [IFG]; n = 81) was determined before counseling. All participants received counseling on infant health benefits, collection and storage of breast milk, and breast pump procurement. Maternal anxiety was measured using the State-Trait Anxiety Inventory (STAI), which was administered to mothers before and after counseling and every 2 weeks until infant discharge. Maternal stress was measured after counseling with the Parental Stressor Scale: NICU. Infant breast milk intake was measured throughout hospitalization. An exit questionnaire that pertained to the perceived benefits and efforts of expressing milk was administered close to the time of infant discharge. RESULTS. After lactation counseling, 100% of the IBG and 85% of the IFG initiated breast milk expression (used the electric breast pump in the hospital) for a total lactation initiation rate of 94%. After adjustment for the mothers who initiated milk expression but did not provide any breast milk, the lactation initiation rate for the entire group was 84%. Non-Hispanic black mothers and Non-Hispanic white mothers initiated milk expression at similarly high rates (95% vs 93%). Also, milk expression initiation was similar for low-income and non–low-income mothers (95% vs 92%). IFG and IBG STAI and Parental Stressor Scale: NICU scores were not significantly different, and there were no significant differences between groups in the change in anxiety after counseling. In addition, the mean difference scores (after counseling − before counseling) for STAI anxiety “state” were not significantly different between groups, even when controlling for “trait” anxiety. State anxiety declined during the first 6 weeks of infant hospitalization in a similar manner for both groups. Maternal trait but not state anxiety scores were inversely correlated with total infant breast milk intake. Breast milk intake (mL/kg per day) was greater in the infants of mothers in the IBG compared with the IFG at each week during the first month and for their entire hospital stay. Infant breast milk intake increased from weeks 1 to 3 in both groups and continued to rise in the fourth week for the IBG. However, breast milk intake declined at week 4 for the IFG. IBG infants received breast milk for 83% of the total fed hospital days (days that feedings were given) compared with 44% of total fed days for the IFG. The proportion of enteral intake that was breast milk was also greater for the IBG compared with IFG during the first 4 weeks and for the total hospitalization. However, the mothers in IFG were able to provide at least 50% of their infants' enteral intake for the first 3 weeks, 48.8% for the fourth week, and 32.8% of the enteral intake for the entire hospitalization. Infants of low-income women received significantly lower amounts of breast milk than did infants of non–low-income mothers. Race and income accounted for 36% of the variance in breast milk intake. Of the 184 mothers who initiated breast milk expression, 72 (39%) completed the exit questionnaire. Infant health benefits were the most common reasons cited by both groups for expressing milk. The most common reasons that both groups reported for ceasing milk expression were (1) low milk supply, (2) returning to work or school, and (3) inability to pump as often as needed. Almost all of the mothers reported that pumping was worth the effort (IBG 100%, IFG 87%), and 100% said that they were glad that the staff helped them with milk expression. CONCLUSION. Counseling mothers of VLBW infants increases the incidence of lactation initiation and breast milk feeding without increasing maternal stress and anxiety.
In lieu of traditional training of examiners to identify cerebral palsy on a neurologic examination at age 1 year, we proposed an alternative approach using a multimedia training video and CD-ROM we developed after a two-step validation process. We hypothesized that use of CD-ROM interactive training will lead to reliable and valid performance of the neurologic examination by both pediatric neurologists and nonpediatric neurologists. All examiners were asked to take one of six interobserver variability tests found on the CD-ROM on two occasions. In the first interobserver variability evaluation, 89% (531 of 594) of the responses agreed with the gold standard responses. Following annotated feedback to the examiners about the two items that had a 60% correct rate, the correct response rate rose to 93% (114 of 123). In the second interobserver variability evaluation, 88% (493 of 560) of the responses agreed with the gold standard responses. Following annotated feedback to the examiners about the four items that had a 70% correct rate, the correct response rate rose to 96% (104 of 108). Interactive CD-ROM examination training is an efficient and cost-effective means of training both neurologists and non-neurologists to perform structured neurologic examinations in 1-year-old children. It provides an effective means to evaluate interobserver variability, offers a route for feedback, and creates an opportunity to reevaluate variability, both immediately and at periodic intervals.
