Objective

To evaluate in-hospital formula supplementation among first-time mothers who intended to exclusively breastfeed and determined if in-hospital formula supplementation shortens breastfeeding duration after adjusting for breastfeeding intention.

Study design

We assessed strength of breastfeeding intentions prenatally in a diverse cohort of expectant primiparae and followed infant feeding practices through day 60. Among mothers planning to exclusively breastfeed their healthy term infants for ≥1 week, we determined predictors, reasons, and characteristics of in-hospital formula supplementation, and calculated the intention-adjusted relative risk (ARR) of not fully breastfeeding days 30-60 and breastfeeding cessation by day 60 with in-hospital formula supplementation (n = 393).

Results

Two hundred ten (53%) infants were exclusively breastfed during the maternity stay and 183 (47%) received in-hospital formula supplementation. The most prevalent reasons mothers cited for in-hospital formula supplementation were: perceived insufficient milk supply (18%), signs of inadequate intake (16%), and poor latch or breastfeeding (14%). Prevalence of not fully breastfeeding days 30-60 was 67.8% vs. 36.7%, ARR 1.8 (95% CI, 1.4-2.3), in-hospital formula supplementation vs exclusively breastfed groups, respectively, and breastfeeding cessation by day 60 was 32.8% vs. 10.5%, ARR 2.7 (95% CI, 1.7-4.5). Odds of both adverse outcomes increased with more in-hospital formula supplementation feeds (not fully breastfeeding days 30-60, P = .003 and breastfeeding cessation, P = .011).

Conclusions

Among women intending to exclusively breastfeed, in-hospital formula supplementation was associated with a nearly 2-fold greater risk of not fully breastfeeding days 30-60 and a nearly 3-fold risk of breastfeeding cessation by day 60, even after adjusting for strength of breastfeeding intentions. Strategies should be sought to avoid unnecessary in-hospital formula supplementation and to support breastfeeding when in-hospital formula supplementation is unavoidable.

Objective

We characterized breastfeeding concerns from open-text maternal responses and determined their association with stopping breastfeeding by 60 days (stopping breastfeeding) and feeding any formula between 30 and 60 days (formula use).

Methods

We assessed breastfeeding support, intentions, and concerns in 532 expectant primiparas and conducted follow-up interviews at 0, 3, 7, 14, 30, and 60 days postpartum. We calculated adjusted relative risk (ARR) and adjusted population attributable risk (PAR) for feeding outcomes by concern category and day, adjusted for feeding intentions and education.

Results

In 2946 interviews, 4179 breastfeeding concerns were reported, comprising 49 subcategories and 9 main categories. Ninety-two percent of participants reported ≥ 1 concern at day 3, with the most predominant being difficulty with infant feeding at breast (52%), breastfeeding pain (44%), and milk quantity (40%). Concerns at any postpartum interview were significantly associated with increased risk of stopping breastfeeding and formula use, with peak ARR at day 3 (eg, stopping breastfeeding ARR [95% confidence interval] = 9.2 [3.0-infinity]). The concerns yielding the largest adjusted PAR for stopping breastfeeding were day 7 "infant feeding difficulty" (adjusted PAR = 32%) and day 14 "milk quantity" (adjusted PAR = 23%).

Conclusions

Breastfeeding concerns are highly prevalent and associated with stopping breastfeeding. Priority should be given to developing strategies for lowering the overall occurrence of breastfeeding concerns and resolving, in particular, infant feeding and milk quantity concerns occurring within the first 14 days postpartum.

Background

Delayed cord clamping (DCC) results in decreased iron deficiency in infancy. The American College of Obstetrics and Gynecology has called for research on the optimal time to clamp the cord during cesarean deliveries (CD). Our objective was to conduct a pilot trial examining the safety of delayed cord clamping (DCC) for maternal-infant dyads during elective cesarean delivery (CD).

Methods

We enrolled 39 dyads [23 at 90 s, 16 at 120 s; (DCC Pilot)] between 10/2013 and 9/2014. We abstracted data from the electronic medical record (EMR) for historical controls (HC) birthing between 1/2012-6/2013 for whom DCC was not performed (n = 112).

Results

Available data for 37 mothers and 30 infants compared to HC revealed 174 (95% CI: 61-286) mL lower mean estimated maternal blood loss [(EBL) mean (SD) mL]: DCC Pilot 691(218) vs. HC 864(442), p = 0.003 and lower incidence of maternal transfusions, DCC Pilot 2.7% vs. HC 18.8%, p = 0.016. There was no significant between group difference between DCC Pilot and HC in other a priori definitions of excess maternal blood loss: a) EBL > 800 ml, 21.6% vs. 38.8%, p = 0.07 or b) post-op hgb/pre-op hgb < 80%, 16.7% vs. 20.6%, p = 0.81. There were also no statistically significant between group differences in rates of NICU admission DCC Pilot 8.1% vs. HC 7.1%, p = 1.0., but there was a higher rate of newborn cold stress or hypothermia ≤36.2 °C in study subjects, DCC Pilot 27.0% vs. HC 11.9%, p = 0.038.Prevalence of newborn anemia was decreased [DCC pilot 3.3% (1 of 30) vs. HC 40.0% (4 of 10 infants with data), p = 0.012. No infants were polycythemic.

Conclusions

These pilot data suggest cord clamping can be delayed to 120 s during elective CD without increased risk of excessive maternal blood loss. More aggressive prevention of infant heat loss may be warranted. A randomized trial to evaluate long-term maternal and infant outcomes is indicated.

Objectives

Low-income, first-time mothers generally breastfeed exclusively and, overall, for a shorter average duration than high-income, multiparous mothers. A potential barrier to breastfeeding success is access to a breast pump for home use. In this pilot study, we estimated the effect of providing a manual breast pump during birth hospitalization for home use on any/exclusive breastfeeding and investigated participant attitudes about manual pumps and their breastfeeding experiences.

Methods

Sixty low-income, first-time mothers were enrolled in a pilot randomized controlled trial. One-half received a manual breast pump and the other half received an attention control. Breastfeeding exclusivity, duration, and use of the manual pump were assessed at 6 and 12 weeks. Qualitative interviews regarding the breastfeeding experience were completed. Thirty-one women answered 13 questions that were then transcribed, coded, and grouped into themes.

Results

Participants who were randomized to manual breast pump receipt during birth hospitalization had increased manual pump use at 6 weeks (13/19 [68%] versus controls 5/17 [29%]), there was no effect of pump receipt on any nor exclusive breastfeeding at 12 weeks. In qualitative analysis of the overall breastfeeding experience, participants expressed a need for additional support and had conflicting attitudes regarding breastfeeding and the pumping experience.

Conclusions

Manual breast pump receipt in hospital among low-income, first-time mothers did not affect breastfeeding exclusivity or duration. Participants reported that early and ongoing lactation support is essential. Strategies to improve breastfeeding outcomes low-income, first-time mothers are needed.

Background

Vitamin B-12 is an essential nutrient required for many functions including DNA synthesis, erythropoiesis, and brain development. If maternal milk vitamin B-12 concentrations are low, infants may face elevated risks of deficiency when exclusively breastfed.

Objective

We evaluated cross-sectional associations between infant serum vitamin B-12 concentrations and maternal milk vitamin B-12 concentrations at 1-6 mo postpartum among an unsupplemented population in rural western Kenya, and assessed biological demographic, and dietary characteristics associated with adequate infant serum vitamin B-12.

Methods

We modeled 1) infant serum vitamin B-12 using maternal milk vitamin B-12 concentration with linear regression; and 2) adequate (>220 pmol/L) infant serum vitamin B-12 using hypothesized biological, demographic, and dietary predictors with logistic regression. In both models, we used generalized estimating equations to account for correlated observations at the cluster-level.

Results

The median (quartile 1, quartile 3) infant serum vitamin B-12 concentration was 276 pmol/L (193, 399 pmol/L) and approximately one-third of infants had serum vitamin B-12 ≤220 pmol/L, indicating that they were vitamin B-12 depleted or deficient. There was a positive correlation between maternal milk and infant serum vitamin B-12 (r = 0.36, P < 0.001) and in multivariable analyses, maternal milk vitamin B-12 concentration was significantly associated with infant serum vitamin B-12 adequacy (P-trend = 0.03).

Conclusions

Despite a high prevalence (90%) of maternal milk vitamin B-12 concentrations below the level used to establish the Adequate Intake (<310 pmol/L), there was a low prevalence of infant vitamin B-12 deficiency. We found few factors that were associated with infant vitamin B-12 adequacy in this population, including infant feeding practices, although maternal vitamin B-12 status was not measured. The contribution of maternal milk to infant vitamin B-12 status remains important to quantify across populations, given that maternal milk vitamin B-12 concentration is modifiable with supplementation. This trial was registered at clinicaltrials.gov as NCT01704105.

The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic has impacted all patient populations including pregnant mothers. There is an incomplete understanding of SARS-CoV-2 pathogenesis and transmission potential at this time and the resultant anxiety has led to variable breastfeeding recommendations for suspected or confirmed mothers with novel coronavirus disease 2019 (COVID-19). Due to the potential concern for transmission of infection from maternal respiratory secretions to the newborn, temporary separation of the maternal-baby dyad, allowing for expressed breast milk to be fed to the infant, was initially recommended but later revised to include breastfeeding by the American Academy of Pediatrics in contrast to international societies, which recommend direct breastfeeding. This separation can have negative health and emotional implications for both mother and baby. Only two publications have reported SARS-CoV-2 in human breast milk but the role of breast milk as a vehicle of transmission of COVID-19 to the newborns still remains unclear and may indeed be providing protective antibodies against SARS-CoV-2 infection even in infected neonates. Other modes of transmission of infection to neonates from infected mothers or any care providers cannot be overemphasized. Symptomatic mothers on hydroxychloroquine can safely breastfeed and no adverse effects were reported in a baby treated with remdesivir in another drug trial. The excretion of sarilumab in human breast milk is unknown at this time. Hence, given the overall safety of breast milk and both short-term and long-term nutritional, immunological, and developmental advantages of breast milk to newborn, breast milk should not be withheld from baby. The setting of maternal care, severity of maternal infection and availability of resources can impact the decision of breastfeeding, the role of shared decision making on breastfeeding between mother and physician needs to be emphasized. We strongly recommend direct breastfeeding with appropriate hygiene precautions unless the maternal or neonatal health condition warrants separation of this dyad. KEY POINTS: · Breastmilk does not appear to play a significant role in transmission of SARS-CoV-2.. · Mother-baby separation has negative health and emotional consequences.. · Mothers with suspected or confirmed COVID-19 can directly breastfeed with appropriate precautions..

Background: Breast milk feeding is an essential component of safe and effective care of the hospitalized premature infant. There are numerous barriers that impact breast milk expression during a preterm infant's hospitalization. We aimed to explore the experience of using videoconferencing with one's hospitalized premature infant while expressing breast milk. Materials and Methods: We conducted a qualitative study using purposive sampling to recruit lactating parents of premature (<34 weeks) hospitalized infants. We conducted semistructured interviews using an interview guide with 14 open-ended questions regarding the breast milk expression experience. Data collection and analysis were performed iteratively and were analyzed using inductive thematic analysis with a constant comparative approach. Data were organized into themes. Interview recruitment was discontinued when thematic saturation was reached. Results: Seventeen participants completed the interviews and four themes were identified: (1) videoconferencing promotes bonding and connection with the hospitalized infant, (2) videoconferencing provides motivation to pump, (3) videoconferencing reminds participants of the realities of separation from their infant, and (4) videoconferencing connects the whole family to the hospitalized infant. Conclusions: Users of videoconferencing with their hospitalized neonate reported an improved pumping experience while expressing milk for their premature infant. Videoconferencing is also a tool that can connect the whole family to the infant. This study was registered at clinicaltrials.gov (clinicaltrials.gov Identifier: NCT03957941) under the title "FamilyLink and Breastfeeding."

Objectives

Newborns hospitalized with unconjugated hyperbilirubinemia without critical comorbidities may receive intensive phototherapy (IP) in non-ICU levels of care, such as a mother-newborn unit, or ICU levels of care. Our aim was to compare outcomes between each level.

Methods

Using hospital discharge data from 2005 to 2011 in New York's State Inpatient Database, we performed multivariate analyses to compare outcomes that included total cost of hospitalization, length of stay, 30-day readmission rate after IP, and the number of cases of death, exchange transfusion, and γ globulin infusion. We included term newborns treated with IP in their first 30 days of life and without diagnosis codes for other critical illnesses. Explanatory variables included level of care, sex, race, insurance type, presence or absence of hemolysis, hospital, volume of IP performed at each hospital, and year of hospitalization.

Results

Ninety-nine percent of IP was delivered in non-ICU levels of care. Incidence of major complications was rare (≤0.1%). After adjusting for confounders, ICU level of care was not associated with difference in length of stay (relative risk: 1.2; 95% confidence interval [CI]: 0.91 to 1.15) or 30-day readmission rate (odds ratio: 0.74; 95% CI: 0.50 to 1.09) but was associated with 1.51 (95% CI: 1.47 to 1.56) times higher costs.

Conclusions

For otherwise healthy term newborns with jaundice requiring IP, most received treatment in a non-ICU level of care, and those in intensive care had no difference in outcomes but incurred higher costs. IP guideline authors may want to be more prescriptive about IP level of care to improve value.
