Evidence-Based Updates on the First Week of Exclusive Breastfeeding Among Infants ≥35 Weeks.

The nutritional and immunologic properties of human milk, along with clear evidence of dose-dependent optimal health outcomes for both mothers and infants, provide a compelling rationale to support exclusive breastfeeding. US women increasingly intend to breastfeed exclusively for 6 months. Because establishing lactation can be challenging, exclusivity is often compromised in hopes of preventing feeding-related neonatal complications, potentially affecting the continuation and duration of breastfeeding. Risk factors for impaired lactogenesis are identifiable and common. Clinicians must be able to recognize normative patterns of exclusive breastfeeding in the first week while proactively identifying potential challenges. In this review, we provide new evidence from the past 10 years on the following topics relevant to exclusive breastfeeding: milk production and transfer, neonatal weight and output assessment, management of glucose and bilirubin, immune development and the microbiome, supplementation, and health system factors. We focus on the early days of exclusive breastfeeding in healthy newborns ≥35 weeks' gestation managed in the routine postpartum unit. With this evidence-based clinical review, we provide detailed guidance in identifying medical indications for early supplementation and can inform best practices for both birthing facilities and providers.

Using linked data to assess patterns of early intervention (EI) referral among very low birth weight infants.

OBJECTIVES: Access to Early Intervention (EI) services may improve cognitive and behavioral outcomes in very low birth weight infants, but few states have population-based data to evaluate EI outreach efforts. We analyzed Massachusetts (MA) infants born weighing <1,200 g to identify maternal and birth characteristics that predicted EI referral and timing of referral. METHODS: MA birth and hospital discharge records (Jan. 1998-Sept. 2000) were linked to EI referral records (Jan. 1998-Sept. 2003) via probabilistic and deterministic methods (88% linkage). Timing of EI referral among infants weighing <1,200 g was examined by infant and maternal characteristics using categorical (0-12 months, 12-36 months, or no referral) time comparisons in the crude analysis. Survival functions calculating median time to referral, and adjusted hazard ratios (HR) with 95% confidence intervals (CI) were calculated for continuous time comparisons of EI referral from birth to 36 months. RESULTS: Of 1,233 infants weighing <1,200 g, 93.2% were referred to EI. After risk adjustment, referral was more likely among multiple-birth infants (HR = 1.17, 95%CI 1.06-1.30) and less likely among infants <28 weeks (HR = 0.70; 95%CI 0.64-0.77) or with low Apgar scores (<5 at 5 min; HR = 0.75; 95%CI 0.62-0.92). EI referrals were lower for infants of black non-Hispanic mothers, and mothers without private insurance (HR = 0.85; 95%CI 0.74-0.98 and HR = 0.77; 95%CI 0.68-0.86, respectively). CONCLUSIONS: In MA, most infants born <1,200 g are referred to EI, but disparities exist. Analysis of linked population-based health and developmental services can inform programs in order to reduce disparities and improve access for all high-risk infants.

Coordination of sucking, swallowing, and breathing and oxygen saturation during early infant breast-feeding and bottle-feeding.

This prospective study compared the coordination of sucking, swallowing, and breathing and its relationship to oxygen saturation in infants during breast-feeding and bottle-feeding. After 4 to 6 wk of exclusive breast-feeding, infants began bottle-feedings of expressed human milk using one of two systems: a soft-walled bottle and nipple (system 1, Playtex) or a hard-walled bottle and nipple (system 2, Avent). Infants' sucking, swallowing, breathing, and oxygenation were measured during breast-feeding and bottle-feeding, and coordination of these activities during breast-feeding and bottle-feeding were compared. During breast-feeding, swallowing occurred nonrandomly between breaths and did not interfere with breathing. The same distribution of swallowing occurred in infants fed with system 1, while swallowing occurred randomly in infants fed with system 2. Swallowing significantly increased during bottle-feeding among infants using system 2, but decreased among infants using system 1. Infants using system 2 also had a greater instability in the coordination of sucking, swallowing, and breathing and more perturbation of breathing. Oxygen saturation was significantly higher in infants fed with system 1 compared with system 2. These results suggest that the overall feeding pattern and oxygenation of system 1 are closer to the physiologic norm than system 2.

Birth characteristics associated with early intervention referral, evaluation for eligibility, and program eligibility in the first year of life.

OBJECTIVES: The Individual with Disabilities Education Act mandates Early Intervention (EI) services for infants and toddlers with developmental delay. We assessed the percentage of infants at risk for developmental delay due to characteristics present at birth who were referred to Massachusetts EI within 1 year of birth, evaluated for eligibility, and eligible for services. In addition, we identified birth characteristics that independently predicted 0-1 year program referral, evaluation, and eligibility. METHODS: The Pregnancy to Early Life Longitudinal (PELL) data system linked birth certificate, hospital discharge, and EI program data of 219,037 infants born in Massachusetts, 1998-2000. Multivariate logistic regressions identified independent infant predictors of referral, evaluation, and eligibility. RESULTS: Of 219,037 births, 14,852 (6.8%) were referred to EI within 1 year. Birthweight<1200 g (OR=9.7, 95% CI 3.3-12.9) and birthweight 1200-1499 g (OR=7.4, 95% CI 5.8-9.5) strongly predicted referral. Referral was high (88%) among infants with two or more birth risks. Among referrals, 88% were evaluated for eligibility. The strongest predictor of evaluation was triplet birth (OR=4.3, 95% CI 1.6-11.8). Among infants evaluated, 85% were determined to be eligible. CONCLUSION: EI referral and evaluation are high among infants born at risk for delay in Massachusetts. Some characteristics not included in the state's high-risk definition (e.g. birthweight 1200-1499 g) were identified that predicted referral. Most referrals were eligible for services. Results demonstrate the value to states of using linked population and program data for program evaluation.

Policies and practices related to breastfeeding in massachusetts: hospital implementation of the ten steps to successful breastfeeding.

BACKGROUND: Hospital policies and practices related to breastfeeding may have long-term health effects. The Ten Steps to Successful Breastfeeding (WHO/UNICEF) provide an evidence-based standard, which may be used to assess individual hospitals. We assessed implementation, and factors related to implementation, of the Ten Steps in Massachusetts hospitals. METHODS: We surveyed postpartum nurse managers at 43 (88%) of the 49 Massachusetts maternity hospitals by telephone. Survey items characterized hospital policies, breastfeeding education, and support practices. We classified hospital implementation of the Ten Steps as high, moderately high, partial, or low and used Massachusetts Department of Public Health hospital data to analyze factors related to implementation. RESULTS: Levels of implementation of the Ten Steps ranged from high to partial. Overall, we classified implementation of 2% of hospitals as high, 58% moderately high, 40% partial, and 0% as low. Hospitals with high/moderately high levels of implementation significantly differed from hospitals with partial implementation with respect to pacifier usage (p=0.0017) and postpartum breastfeeding instruction (p=0.0001). Requirement of a physician order for formula was a statistically significant (p=0.02) predictor of Step 1 implementation but did not reach significance (p=0.14) overall. Acceptance of free formula was significantly associated (p=0.03) with overall Ten Steps implementation. CONCLUSION: Rates of self-reported implementation of the Ten Steps are relatively high in Massachusetts. Step 1 implementation is significantly associated with formula availability, and overall implementation with acceptance of free formula. Continued assessment is needed to confirm these results in larger samples and to examine the relationship of implementation of individual steps, breastfeeding rates, and health outcomes.

Neurodevelopmental outcome and growth at 18 to 22 months' corrected age in extremely low birth weight infants treated with early erythropoietin and iron.

BACKGROUND: Clinical trials evaluating the use of erythropoietin (Epo) have demonstrated a limited reduction in transfusions; however, long-term developmental follow-up data are scarce. OBJECTIVE: We compared anthropometric measurements, postdischarge events, need for transfusions, and developmental outcomes at 18 to 22 months' corrected age in extremely low birth weight (ELBW) infants treated with early Epo and supplemental iron therapy with that of placebo/control infants treated with supplemental iron alone. METHODS: The National Institute of Child Health and Human Development Neonatal Research Network completed a randomized, controlled trial of early Epo and iron therapy in preterm infants < or =1250 g. A total of 172 ELBW (< or =1000-g birth weight) infants were enrolled (87 Epo and 85 placebo/control). Of the 72 Epo-treated and 70 placebo/control ELBW infants surviving to discharge, follow-up data (growth, development, rehospitalization, transfusions) at 18 to 22 months' corrected age were collected on 51 of 72 Epo-treated infants (71%) and 51 of 70 placebo/controls (73%) by certified examiners masked to the treatment group. Statistical significance was determined using chi2 analysis. RESULTS: There were no significant differences between treatment groups in weight or length or in the percentage of infants weighing <10th percentile either at the time of discharge or at follow-up, and no difference was found in the mean head circumference between groups. A similar percentage of infants in each group was rehospitalized (38% Epo and 35% placebo/control) for similar reasons. There were no differences between groups with respect to the percentage of infants with Bayley-II Mental Developmental Index <70 (34% Epo and 36% placebo/control), blindness (0% Epo and 2% placebo/control), deafness or hearing loss requiring amplification (2% Epo and 2% placebo/control), moderate to severe cerebral palsy (16% Epo and 18% placebo/control) or the percentage of infants with any of the above-described neurodevelopmental impairments (42% Epo and 44% placebo/control). CONCLUSIONS: Treatment of ELBW infants with early Epo and iron does not significantly influence anthropometric measurements, need for rehospitalization, transfusions after discharge, or developmental outcome at 18 to 22 months' corrected age.
