Use of a Supplemental Feeding Tube Device and Breastfeeding at 4 Weeks.

BACKGROUND: Mothers having difficulty breastfeeding their infants may use alternative supportive feeding methods. Although a supplemental feeding tube device is commonly used, efficacy for supporting sustained breastfeeding remains unknown. PURPOSE: To describe supplemental feeding tube device use by breastfeeding mothers as an alternative feeding method through exploration of associations between supplemental feeding tube device use and continued breastfeeding at 4 weeks of infant's age. METHOD: Forty mothers participated. They were interviewed during the birth hospitalization and at 4 weeks postpartum. Questions addressed use of supplemental feeding tube devices, breastfeeding issues, and continued breastfeeding relationships. We examined the relationship between LATCH scores at 2 to 3 days of life. RESULTS: Breastfeeding mothers who chose to supplement with bottle-feeding instead of use of a supplemental feeding tube device were 30% less likely to continue breastfeeding at a medium/high/exclusive level. CONCLUSION: Use of the supplemental feeding tube device may help avoid the potentially detrimental effect of bottle-feeding on continued breastfeeding.

A Scoping Review of Neonatal Opioid Withdrawal and the Infant Gut Microbiome: Does Human Milk Optimize Infant Outcomes?

BACKGROUND: While a growing body of literature has established the role of human milk as a mechanism of protection in the formation of the infant gut microbiome, it remains unclear the extent to which this association exists for infants with neonatal opioid withdrawal syndrome. PURPOSE: The purpose of this scoping review was to describe the current state of the literature regarding the influence of human milk on infant gut microbiota in infants with neonatal opioid withdrawal syndrome. DATA SOURCES: CINAHL, PubMed, and Scopus databases were searched for original studies published from January 2009 through February 2022. Additionally, unpublished studies across relevant trial registries, conference proceedings, websites, and organizations were reviewed for possible inclusion. A total of 1610 articles met selection criteria through database and register searches and 20 through manual reference searches. STUDY SELECTION: Inclusion criteria were primary research studies, written in English, published between 2009 and 2022, including a sample of infants with neonatal opioid withdrawal syndrome/neonatal abstinence syndrome, and focusing on the relationship between the receipt of human milk and the infant gut microbiome. DATA EXTRACTION: Two authors independently conducted title/abstract and full-text review until there was consensus of study selection. RESULTS: No studies satisfied the inclusion criteria, which resulted in an empty review. IMPLICATIONS FOR PRACTICE AND RESEARCH: Findings from this study document the paucity of data exploring the associations between human milk, the infant gut microbiome, and subsequent neonatal opioid withdrawal syndrome. Further, these results highlight the timely importance of prioritizing this area of scientific inquiry.

Applying a Reproductive Justice Lens to Enhance Research Engagement Among Systematically Underrepresented Childbearing Women.

BACKGROUND: Historically, childbearing women from diverse and systematically hard-to-reach populations have been excluded from nursing research. This practice limits the generalizability of findings. Maximizing research strategies to meet the unique needs of these populations must be a priority. OBJECTIVES: The aim of this study was to provide methodological context for the comprehensive application of reproductive justice strategies to guide research methods and promote engagement of underrepresented childbearing women while decreasing systemic bias. METHODS: In this article, we use a reproductive justice lens to characterize and define strategies for enhancing ethical and equitable engagement in research involving childbearing women who are often systematically underrepresented using a case study approach. Using a specific case study exemplar, the core tenets of reproductive justice are outlined and affirm the need to advance research strategies that create ethical engagement of diverse populations, transform oppressive social structures, and shift research paradigms so research objectives intentionally highlight the strengths and resiliency inherent to the targeted communities. RESULTS: We begin by describing parallels between the tenets of reproductive justice and the ethical principles of research (i.e., respect for persons, beneficence, and justice). We then apply these tenets to conceptualization, implementation (recruitment, data management, and retention), and dissemination of research conducted with childbearing women from diverse backgrounds who are systemically underrepresented. We highlight our successful research strategies from our case study example of women with histories of incarceration. DISCUSSION: To date, outcomes from our research indicate the need for multilevel strategies with a focus on respectful, inclusive participant and key community partner engagement; the time investment in local communities to promote equitable collaboration; encouragement of the patient's autonomous right to self-determination; and mitigation of power imbalances. Nurse researchers are well positioned to advance research justice at the intersection of reproductive justice and ethics to fully engage diverse populations in advancing health equity to support the best health outcomes.

Stigmatization of Pregnant Individuals with Opioid Use Disorder.

Objective: The purpose of this study was to critically analyze the role of stigma in the care of pregnant and parenting individuals with opioid use disorder (OUD) through the theoretical lens of the Reproductive Justice (RJ) framework. Background: Overdose related maternal mortality, often involving opioids, is a national growing public health concern. OUD is a highly stigmatized condition that may negatively influence the well-being of pregnant/parenting individual's reproductive and human rights. Study Design: Secondary qualitative data analysis. Methods: A secondary data analysis was conducted using individual interviews (N = 23) from a larger study aimed at examining contextual factors surrounding pregnant/parenting individual's experiences with opioid use return to use and/or overdose. The RJ framework was used as a framework to examine the influence of OUD-related stigma and a person's right to bodily autonomy, their right to parent, and their right to parent the children they have in safe and sustainable environments. Results: The RJ framework supported the examination of factors that perpetuate stigma in this population. Individuals described stigmatizing experiences in the health care setting. Verbal and nonverbal interactions with health care providers and fear of child welfare involvement were counterproductive to recovery and potentially triggered OUD recurrence and/or overdose. Conclusions: Due to existing stigma, pregnant and parenting individuals with OUD often avoided health care and recovery support services; therefore, there should be the removal of barriers that prevent this population from accessing life-saving services. Future efforts should focus on health policy-related research to support structural changes within institutions.

A Meta-Analysis of Breastfeeding Effects for Infants With Neonatal Abstinence Syndrome.

BACKGROUND: Neonatal abstinence syndrome (NAS) rates have dramatically increased. Breastfeeding is a nonpharmacological intervention that may be beneficial, reducing NAS symptom severity and thus the need for and duration of pharmacological treatment and length of hospital stay. OBJECTIVES: Conduct meta-analysis to determine whether breastfeeding results in better outcomes for NAS infants. Variables included symptom severity, need for and duration of pharmacological treatment, and length of hospital stay. METHODS: PubMed, Scopus, Embase, and Cochrane Library were searched from 2000 to 2020, and comparative studies examining breastfeeding for NAS infants were extracted. Randomized trials and cohort studies were included. Data were extracted and evaluated with Review Manager Version 5.3. A random-effects model was used to pool discontinuous outcomes using risk ratio and 95% confidence intervals. Continuous outcomes were evaluated by mean differences and 95% confidence intervals. RESULTS: Across 11 studies, 6,375 neonates were included in the meta-analysis. Using a random-effects analysis, breastfeeding reduced initiation of pharmacological treatment, reduced duration of pharmacological treatment, and reduced length of stay. No differences were detected for severity of NAS symptoms. Most studies only reported one to two variables of interest. For most studies, these variables were not the primary study outcomes. All studies were found to be of low risk and good quality based on the Cochrane Risk Assessment Tools. Varying breastfeeding definitions limit generalizability. DISCUSSION: Breastfeeding is associated with decreased initiation and duration of pharmacological treatment and length of stay.

Recovering Together: Mothers' Experiences Providing Skin-to-Skin Care for Their Infants With NAS.

BACKGROUND: Over the past 2 decades, the prevalence of neonatal abstinence syndrome (NAS) has increased almost 5-fold. Skin-to-skin care (SSC), a method of parent-infant holding, is a recommended nonpharmacologic intervention for managing NAS symptoms. SSC has the potential to reduce withdrawal symptoms while positively influencing parent-infant attachment. Yet, little is known about the SSC experiences of mothers of infants with NAS. PURPOSE: The purpose of this study was to explore the SSC experiences of mothers of infants with NAS, including perceived barriers to SSC in the hospital and following discharge home. METHODS: A qualitative descriptive design was used to obtain new knowledge regarding the experience of SSC of mothers of infants with NAS. Purposive sampling was used to recruit participants eligible for the study. We conducted semistructured individual interviews with postpartum mothers of infants with NAS. Data were analyzed using thematic analysis. FINDINGS/RESULTS: Thirteen mothers participated in the study. Four themes emerged from the data analysis: "a little nerve racking"; "she needed me, and I needed her"; dealing with the "hard times"; and "a piece of my puzzle is missing." SSC was described as a conduit for healing and bonding; in addition, several barriers to SSC were reported. IMPLICATIONS FOR PRACTICE AND RESEARCH: These findings highlight the inherent benefits of SSC for infants with NAS and demonstrate the unique challenges of these mother-infant dyads. Critical changes in hospital practices are needed to create an environment supportive of SSC for this patient population. In addition, research regarding implementation of interventions to increase SSC usage in this population is warranted.

Maternal H-antigen secretor status is an early biomarker for potential preterm delivery.

OBJECTIVE: Pre-pregnancy or first trimester biomarkers predicting preterm delivery are lacking. The purpose of this study was to determine whether maternal H-antigen (secretor status) is a potential biomarker for preterm delivery. METHODS: This cohort study examined maternal saliva samples and birth data gathered by the National Children's Study Vanguard pilot phase (2009-2014) and included 300 women who were ≥18 years old and provided birth data and saliva samples. The maternal secretor status phenotype was determined by quantifying H-antigen in saliva using enzyme-linked immunoassay. Mothers were stratified by secretor status and multivariable analysis estimated adjusted associations with preterm delivery. RESULTS: Maternal lack of H-antigen production was an independent risk factor for preterm delivery after adjusting for known confounders (aOR 4.53; 95% CI: 1.74, 11.81; P = 0.002). CONCLUSIONS: Maternal H-antigen may be a biomarker identifying women at-risk for preterm delivery. Prospective cohort studies validating these findings are needed.

Demographics and Geographic Distribution of Mothers Donating to a Nonprofit Milk Bank.

Background: The Human Milk Banking Association of North America (HMBANA) is a nonprofit association that standardizes and facilitates the establishment and operation of nonprofit donor human milk banks in North America. Few studies have examined milk donor characteristics and geographic distribution, and little is known about how donor characteristics change with time. Materials and Methods: We performed a retrospective cohort study of mothers who donated to Mothers' Milk Bank Northeast (MMBNE) between January 1, 2011 and September 1, 2019. Data collected from MMBNE donor surveys and collection procedures were analyzed using descriptive and comparative statistics. Donor characteristics were examined for secular trends. Results: Donors (n = 3,764) were of mean age 32.5 years (median 32; IQR 30-35) and most donated more than once (median 2; IQR 1-3; range 1-41). The majority of donors gave birth to term infants and resided in New England; however, MMBNE donors were located in 39 states at the time of donation. Median total volume donated per donor was median 11,396 mL (380 Oz); IQR 6,020-24,242 mL. Mothers of preterm compared with term infants were more likely to be bereaved (p < 0.01) and donated larger volumes (p < 0.01). Over time, number of first-time donors increased, although donors became less likely to have preterm infants or to reside in Massachusetts or New England. Conclusions: Donors to MMBNE varied greatly in age and were broadly distributed geographically. Donor characteristics changed substantially over time. Enhanced understanding of the characteristics of donors may improve the efficiency of efforts to promote milk donation.

Stress and Drug Use from Prepregnancy, During Pregnancy, to Postpartum.

OBJECTIVE: To document changes of stress and illicit drug use among women from 4 months prepregnancy to 6 months postpartum. STUDY DESIGN: In a longitudinal study of drug use in family planning clinics, 121 women who became pregnant were matched with 202 women who did not become pregnant. Self-reported drug use, Cohen's Perceived Stress Scale, and open-ended stress questions were examined every 2 months during the study period of time. RESULTS: Among drug-using pregnant women, drug use declined during 2nd and 3rd trimesters and increased immediately within 1 to 2 months postpartum. Levels of perceived stress declined throughout pregnancy up to 2 months postpartum, increased at 3 to 4 months postpartum and then declined at 6 months postpartum. In contrast, among nondrug-using pregnant women, stress remained stable until the 2nd trimester, increased from 3rd trimester to 1-2 months postpartum, then declined continuously to 6 months postpartum. For non-pregnant women, at the matched timeline, there was no clear pattern for changes of drug use and stress. CONCLUSIONS: Our study has illustrated a complex time course of changes of both perceived stress and drug use from prepregnancy through 6 months postpartum. For drug-using pregnant women, pregnancy showed protective effect in reduction of both drug use and stress during pregnancy; and during postpartum, drug resumption peaked at 1-2 months while stress peaked at 3-4 months. If we can identify modifiable, pregnancy-related resiliency factors for both stress and drug use, we can begin to extend prevention efforts initiated during pregnancy into the postpartum period.

Individualized versus standard diet fortification for growth and development in preterm infants receiving human milk.

BACKGROUND: Human milk as compared to formula reduces morbidity in preterm infants but requires fortification to meet their nutritional needs and to reduce the risk of extrauterine growth failure. Standard fortification methods are not individualized to the infant and assume that breast milk is uniform in nutritional content. Strategies for individualizing fortification are available; however it is not known whether these are safe, or if they improve outcomes in preterm infants. OBJECTIVES: To determine whether individualizing fortification of breast milk feeds in response to infant blood urea nitrogen (adjustable fortification) or to breast milk macronutrient content as measured with a milk analyzer (targeted fortification) reduces mortality and morbidity and promotes growth and development compared to standard, non-individualized fortification for preterm infants receiving human milk at < 37 weeks' gestation or at birth weight < 2500 grams. SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 9), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), on September 20, 2019. We also searched clinical trials databases and the reference lists of retrieved articles for pertinent randomized controlled trials (RCTs) and quasi-randomized trials. SELECTION CRITERIA: We considered randomized, quasi-randomized, and cluster-randomized controlled trials of preterm infants fed exclusively breast milk that compared a standard non-individualized fortification strategy to individualized fortification using a targeted or adjustable strategy. We considered studies that examined any use of fortification in eligible infants for a minimum duration of two weeks, initiated at any time during enteral feeding, and providing any regimen of human milk feeding. DATA COLLECTION AND ANALYSIS: Data were collected using the standard methods of Cochrane Neonatal. Two review authors evaluated the quality of the studies and extracted data. We reported analyses of continuous data using mean differences (MDs), and dichotomous data using risk ratios (RRs). We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS: Data were extracted from seven RCTs, resulting in eight publications (521 total participants were enrolled among these studies), with duration of study interventions ranging from two to seven weeks. As compared to standard non-individualized fortification, individualized (targeted or adjustable) fortification of enteral feeds probably increased weight gain during the intervention (typical mean difference [MD] 1.88 g/kg/d, 95% confidence interval [CI] 1.26 to 2.50; 6 studies, 345 participants), may have increased length gain during the intervention (typical MD 0.43 mm/d, 95% CI 0.32 to 0.53; 5 studies, 242 participants), and may have increased head circumference gain during the intervention (typical MD 0.14 mm/d, 95% CI 0.06 to 0.23; 5 studies, 242 participants). Compared to standard non-individualized fortification, targeted fortification probably increased weight gain during the intervention (typical MD 1.87 g/kg/d, 95% CI 1.15 to 2.58; 4 studies, 269 participants) and may have increased length gain during the intervention (typical MD 0.45 mm/d, 95% CI 0.32 to 0.57; 3 studies, 166 participants). Adjustable fortification probably increased weight gain during the intervention (typical MD 2.86 g/kg/d, 95% CI 1.69 to 4.03; 3 studies, 96 participants), probably increased gain in length during the intervention (typical MD 0.54 mm/d, 95% CI 0.38 to 0.7; 3 studies, 96 participants), and increased gain in head circumference during the intervention (typical MD 0.36 mm/d, 95% CI 0.21 to 0.5; 3 studies, 96 participants). We are uncertain whether there are differences between individualized versus standard fortification strategies in the incidence of in-hospital mortality, bronchopulmonary dysplasia, necrotizing enterocolitis, culture-proven late-onset bacterial sepsis, retinopathy of prematurity, osteopenia, length of hospital stay, or post-hospital discharge growth. No study reported severe neurodevelopmental disability as an outcome. One study that was published after our literature search was completed is awaiting classification. AUTHORS' CONCLUSIONS: We found moderate- to low-certainty evidence suggesting that individualized (either targeted or adjustable) fortification of enteral feeds in very low birth weight infants increases growth velocity of weight, length, and head circumference during the intervention compared with standard non-individualized fortification. Evidence showing important in-hospital and post-discharge clinical outcomes was sparse and of very low certainty, precluding inferences regarding safety or clinical benefits beyond short-term growth.

The Role of Stigma in the Nursing Care of Families Impacted by Neonatal Abstinence Syndrome.

BACKGROUND: The current US opioid crisis has resulted in a significant increase in opioid use disorder among pregnant and parenting women. Substance use disorders, in general, are highly stigmatized conditions. Stigma serves as a well-documented global barrier to health-seeking behaviors and engagement in healthcare. While extensive research exists on the stigma of mental illness, few studies have explored the stigma experienced by families impacted by neonatal abstinence syndrome (NAS). PURPOSE: Therefore, the purpose of this article is to explore the role of stigma in the care of families impacted by NAS. METHODS: In this article, we present a discussion about the effects of stigma on this patient population and provide exemplars of stigma experiences from our previous research and the existing literature. FINDINGS/RESULTS: Mothers of infants with NAS faced the challenges of overcoming stigma as they were often ostracized, excluded, and shamed. Nurses who provide care for these women and their infants have reported experiencing ethical distress, moral distress, and compassion fatigue. IMPLICATIONS FOR PRACTICE: Greater awareness of the impact of opioid use on the maternal-child population has resulted in numerous educational offerings for healthcare providers; however, this alone is not adequate to end stigma. Fortunately, promising tools and methods have been developed for assisting nurses with addressing stigma in a manner that can be both nonconfrontational and highly effective. IMPLICATIONS FOR RESEARCH: Future research is needed to explore and evaluate the efficacy of various existing strategies for counteracting harmful stigma in this patient population.

Feeding Behaviors in Infants With Prenatal Opioid Exposure: An Integrative Review.

BACKGROUND: Oral feeding is one of the most complex maturational skills of infancy. Difficulties with feeding require specialized attention, and if not well managed, may prolong the newborn's hospital length of stay. This is particularly true for prenatally opioid exposed (POE) infants. A paucity of literature exists characterizing feeding behaviors of POE infants, yet feeding problems are common. PURPOSE: The purpose of this integrative review was to synthesize and critically analyze the evidence that characterizes feeding behaviors in full-term, POE infants. METHODS/SEARCH STRATEGY: The electronic databases of CINAHL, PubMed, Scopus, and PsycINFO were used. Inclusion criteria were studies in English, conducted from 1970 to 2019, with participant samples consisting of infants with prenatal opioid exposure, born full-term, and between 38 and 40 weeks of gestation. Based on the inclusion criteria, our search yielded 557 articles. After further screening, only 4 studies met our full inclusion/exclusion criteria. These studies were analyzed for evidence of infant feeding behaviors, including characterization of problematic feeding behavior for POE infants. FINDINGS/RESULTS: Our findings revealed inconsistencies in characterization of feeding behaviors among POE infants. A synthesis of the most common evidence-based behaviors was constructed. Infant feeding behaviors were identified and grouped into 2 major behavior domains: (1) typical feeding behavior and (2) problematic feeding behavior. IMPLICATIONS FOR PRACTICE AND RESEARCH: Feeding behaviors related to sucking and behavioral states may be different in POE infants. Further examination of effective assessment methods and the categorization of infant feeding behaviors are warranted for use in the development of evidence-based, targeted intervention.

Comparison of Types of Breast Milk Fortification at Discharge from the Neonatal Intensive Care Unit and Breast Milk Feeding Rates and Growth at 4 Months Corrected Age.

Background: Effects of breast milk (BM) enhancement on long-term BM feeding in preterm infants discharged from the neonatal intensive care unit (NICU) have not been examined previously. This study compares any BM feeding rates at 4 months corrected age (CA) in preterm infants discharged from the NICU on BM enhancement by fortification of expressed BM with infant formula additives (BM-F) versus BM supplemented with infant formula feeds (BM-S). Subjects and Methods: We compared infants born between January 1, 2013, and December 31, 2017, with gestational age <32 weeks or birth weight <1500 g, discharged home on BM-F or BM-S from two NICUs and followed at 4 months CA. Multivariate logistic regression with propensity scoring estimated the adjusted associations between nutrition at discharge and any BM feeding at 4 months CA. Results: Two hundred eighty-five infants were followed at 4 months CA. Infants discharged on BM-F were more likely to have mothers with multiple gestation, private insurance and not Caucasian, initiate feeds of human milk, be discharged from NICU-1, and receive any BM at 4 months CA (p < 0.03). No significant difference in growth parameters <10th percentile at 4 months CA was observed between the two groups. After adjusting for confounding factors, discharge from the NICU on BM-F was significantly associated with BM feeding at 4 months CA (odds ratio: 3.89, 95% confidence interval 1.66-9.14, p = 0.002). Conclusion: In this observational study, preterm infants receiving BM fortified with formula powder additives at discharge from the NICU had better BM feeding outcomes without poor growth at 4 months CA relative to those infants receiving BM supplemented with infant formula feeds.

The Nutritional Composition and Energy Content of Donor Human Milk: A Systematic Review.

The American Academy of Pediatrics recommends donor human milk (DHM) as the preferred feeding strategy for preterm infants when the milk of the mother is unavailable, based on conclusive evidence of lower rates of necrotizing enterocolitis with DHM feedings compared with preterm infant formula. The nutritional composition of DHM may differ from maternal milk for many reasons including differences in maternal characteristics, milk collection methods, and the impact of donor milk banking practices. The purpose of this systematic review is to examine the literature regarding research on the fat, protein, carbohydrate, vitamin, and mineral composition of DHM obtained through nonprofit milk banks or commercial entities. PubMed, CINAHL, and Scopus databases were searched for articles published between 1985 and 30 April, 2019. In total, 164 abstracts were screened independently by 2 investigators, and 14 studies met all inclusion criteria. Studies were predominantly small (<50 samples) and measured macronutrients. Few studies assessed vitamins and minerals. Information bias was prevalent due to the use of a variety of analytical methods which influence accuracy and cross-study comparisons. Other sources of information bias included missing information regarding methods for protein and calorie assessment. Despite these limitations, existing research suggests the potential for 2-fold and greater differences in the fat, protein, and energy composition of DHM, with mean values for energy and fat often below clinical reference values expected for human milk. Further research is warranted regarding the nutritional composition of DHM, with a prioritization on measuring macronutrients and micronutrients using established reference methods.

Macronutrient analysis of donor human milk labelled as 24 kcal/oz.

OBJECTIVE: To measure the macronutrient content (MNC) of donor human milk labelled as 24 kcal/oz ("high-calorie DHM," hcDHM), compare to bank-labelled MNC, and examine variability of hcDHM MNC among milk banks. STUDY DESIGN: MNC was measured with near-infrared spectroscopy for 75 convenience samples from five milk banks collected during September 2016-July 2017. Concordance of measured MNC with labelled values was evaluated using three different thresholds: within ±20%, similar to FDA labelling standards for class II nutrients in foods; ±10%; and ±5%. RESULTS: Protein and caloric content differed significantly between measured and labelled values and varied significantly among milk banks. Measured caloric content ranged from 16.50 to 30.27 kcal/oz, with 89.3% of hcDHM samples within ±20%, 58.7% within ±10%, and 18.7% within ±5% of labelled content. CONCLUSIONS: MNC of hcDHM used in clinical practice shows variation that may result in differences from desired diet. The clinical implications of such differences are unexplored.

Delayed Achievement of Oral Feedings Is Associated with Adverse Neurodevelopmental Outcomes at 18 to 26 Months Follow-up in Preterm Infants.

OBJECTIVE: This study aimed to compare neurodevelopmental outcomes in preterm infants at 18 to 26 months corrected age (CA) who did versus did not achieve full oral feedings at 40 weeks postmenstrual age (PMA). STUDY DESIGN: This retrospective study included infants born between 2010 and 2015 with gestational age <32 weeks and followed between 18 and 26 months CA. Achievement of full oral feedings was defined as oral intake >130 mL/kg/d for >72 hours by 40 weeks PMA. Incidence of cognitive, language, or motor delay, or cerebral palsy at 18 to 26 months CA was compared in multivariable analyses for infants in the two feeding groups. RESULTS: Of 372 included infants, those achieving full oral feedings had lower incidence of any adverse neurodevelopmental outcome (p < 0.001) compared with those who did not achieve full oral feedings. In multivariable analyses, achievement of full oral feedings by 40 weeks PMA was associated with decreased odds of cognitive, language, and motor delays, cerebral palsy, and any adverse neurodevelopmental outcome at follow-up. CONCLUSION: Achievement of full oral feedings by 40 weeks PMA was associated with better adjusted neurodevelopmental outcomes at 18 to 26 months CA. Inability to fully feed orally at 40 weeks PMA may be a simple, clinically useful marker for risk of adverse neurodevelopmental outcomes.

Preterm infant gut microbial patterns related to the development of necrotizing enterocolitis.

Objectives: To define gut microbial patterns in preterm infants with and without necrotizing enterocolitis (NEC) and to characterize clinical factors related to the composition of the preterm intestinal microbiome.Methods: Fecal samples were collected at one-week intervals from infants with gestational ages <30 weeks at a single level IV neonatal intensive care unit. Using 16S rRNA gene sequencing, the composition and diversity of microbiota were determined in samples collected from five NEC infants and five matched controls. Hierarchical linear regression was used to identify clinical factors related to microbial diversity and specific bacterial signatures.Results: Low levels of diversity were demonstrated in samples obtained from all preterm infants and antibiotic exposure further decreased diversity among both NEC cases and controls. Fecal microbial composition differed between NEC cases and controls, with a greater abundance of Proteobacteria and bacteria belonging to the class Gammaproteobacteria among NEC infants. Control infants demonstrated a greater abundance of bacteria belonging to the phylum Firmicutes.Conclusion: These findings indicate that an association exists between intestinal Proteobacteria and NEC, and strengthens the notion that an overly exuberant response to Gram-negative products, particularly lipopolysaccharide, in the preterm intestine is involved in NEC pathogenesis. Cumulative exposure to antibiotics corresponded to a reduction in microbial diversity in both NEC cases and controls.

Accuracy and Reliability of Infrared Analyzers for Measuring Human Milk Macronutrients in a Milk Bank Setting.

BACKGROUND: Infrared (IR) analysis is an emerging technology that may be a useful tool for milk banks to manage the nutrient variability in donor human milk. OBJECTIVE: To evaluate the accuracy, reliability, and comparability of commercial infrared analyzers for measuring human milk macronutrients in a milk bank setting. METHODS: Three nonprofit milk banks received blinded test kits of human milk that had been assessed using reference methods. Four infrared instruments were used to measure macronutrients as follows: 1 filtered mid-IR, 2 Fourier-transformed full-spectra mid-IR, and 1 near-IR. Twenty-five unique samples were read concurrently for the accuracy arm. An identical sample was read daily for 1 mo for the reliability arm. RESULTS: Values for R 2 describing relationships with reference methods for total fat, crude protein, and lactose, were as follows: filtered mid-IR, 0.98, 0.94, and 0.48; Fourier-transformed full-spectra mid-IR, 0.97, 0.93, and 0.36 for instrument 1 and 0.98, 0.98, and 0.31 for instrument 2; and near-IR 0.93, 0.93, and 0.12. There was no significant difference between instruments for crude protein and total fat measurements. There were significant differences in carbohydrate measurements between instruments. For 1 mo of daily measurements in the reliability arm, CVs for filtered mid-IR were ≤4.6%, for Fourier-transformed full spectra mid-IR were ≤1.7%, and for near-IR were ≤5.1%. CONCLUSIONS: Infrared analysis is an accurate and reliable method for measuring crude protein and total fat in a milk bank setting. Carbohydrate measurements are less accurate and are significantly different between instruments, which will likely lead to differences in derived calorie values.

Predictors of Mother's Own Milk Feeding at Discharge in Preterm Infants.

BACKGROUND: The dose-response benefits of human milk for preterm infants are well documented. Understanding factors that influence duration of mother's own milk (MOM) receipt may have important clinical implications. PURPOSE: To identify variables that significantly affect whether or not preterm infants receive their own mother's milk at discharge. METHODS: Maternal-infant dyads were eligible for inclusion if the infant was born between August 1, 2010, and July 31, 2015, was born at 32 weeks' gestation or less, or was 1800 g or less (institutional donor milk receipt criteria). Bivariate and multivariable regression analyses were performed. RESULTS: Of 428 observations, 258 (60.3%) received MOM at discharge and 170 (39.7%) did not. Maternal characteristics that were protective for MOM receipt at discharge were non-Hispanic race, married, partner support, more educated, and private insurance. Protective infant characteristics were higher gestational age at birth, higher percentage of MOM feedings, fewer ventilator days, and more days of direct lactation. In multivariable logistic regression, the odds of receiving MOM at discharge significantly (odds ratio = 1.93; 95% confidence interval, 1.72-2.16; P < .001) increased with the increasing proportion of MOM. Regression analysis showed that gestational age and increased maternal age increased the likelihood of MOM receipt at discharge. IMPLICATIONS FOR PRACTICE: Clinicians will understand the significant effects even small increases in milk volume have on duration of MOM receipt at discharge, informing them of the importance of strategies to encourage and improve milk expression. IMPLICATIONS FOR RESEARCH: Future research studying critical time periods when mothers are most likely to reduce milk expression may have significant clinical importance.

International Board Certified Lactation Consultants' Practices Regarding Supplemental Feeding Methods for Breastfed Infants.

BACKGROUND: According to the Baby Friendly Hospital Initiative, when supplementary feeding occurs, mothers should be counseled on the use and risks of feeding bottles and teats. To help support this initiative it is important to understand the supplementation practices of Internationally Board Certified Lactation Consultants (IBCLC)®. RESEARCH AIMS: To determine (1) if the location of an IBCLC's practice has any impact on supplemental feeding methods; (2) the preferred methods of and the main reasons for supplementation; (3) the level of an IBCLC's confidence with supplemental feeding methods; (4) who is making supplemental feeding decisions; and (5) if there are geographical differences among supplementation choices and reasons for supplementation. METHODS: An exploratory, descriptive, cross sectional survey of IBCLCs was conducted to generate data about their use of supplemental feeding methods. The survey was sent via email invitation through the International Board of Lactation Consultant's Board of Examiners, with a response rate of 11.5% (N = 2,308). RESULTS: There was no standard method of supplementation among participants. Participants indicated that they were confident advising mothers on alternative feeding methods. Only 17.6% (n = 406) of participants reported that the IBCLC was the caregiver who recommended the method of supplementation used. The majority of participants believed the Supplemental Feeding Tube Device SFTD) best preserves the breastfeeding relationship, and this was their preferred method of supplementation. However, the bottle was ranked as the number one method used in the United States, Australia, and Canada. The use of alternative feeding methods may be overwhelming to the mother. CONCLUSION: Supplementation by alternative feeding methods might help preserve the breastfeeding relationship and help reach the World Health Organization's goal of increasing exclusive breastfeeding rates.
