Background: Full oral feeding (FOF) is a critical milestone in preterm infants, often delayed because of immature feeding coordination. The Fucile oral motor stimulation protocol aims to address these challenges and enhance feeding progression. To evaluate the effectiveness of the Fucile oral motor stimulation protocol in reducing the transition time to FOF, shortening hospital stays, and improving feeding-related outcomes in preterm infants. Methods: A systematic review and meta-analysis was conducted following the PRISMA guidelines (PROSPERO: CRD42022369514). Databases, including PubMed, Scopus, Web of Science, CENTRAL, and CINAHL (1990-2024), were searched. Randomized controlled trials comparing the Fucile protocol with control interventions in preterm infants (<37 weeks of gestation) were included. Outcomes included transition time to FOF, hospital stay length, weight at discharge, and milk transfer rate. Risk of bias (RoB 2) and evidence certainty (Grading of Recommendations Assessment, Development, and Evaluation) were evaluated. Results: Nineteen trials (1,031 infants) showed that the Fucile protocol significantly reduced transition time to FOF (mean difference [MD]: -5.77 days; 95% confidence interval [CI]: -6.64 to -4.90) and hospital stay duration (MD: -6.47 days; 95% CI: -8.41 to -4.53) with moderate-certainty evidence. Conclusion: The Fucile protocol accelerates feeding milestones and reduces hospital stays for preterm infants, providing moderate-certainty evidence to support its clinical use. However, methodological limitations, including small sample sizes and risk of bias, underline the need for larger, high-quality trials to confirm these findings and refine clinical guidelines. These results suggest the potential of integrating oral motor stimulation into neonatal intensive care unit practices to enhance feeding outcomes and optimize care for preterm infants.

Introduction: Tetrahydrocannabinol (THC), the major psychoactive marijuana cannabinoid, can be transferred to neonates via maternal breast milk (MBM) feeds, but available literature on the safety of concomitant breastfeeding and THC use is inconsistent. This study aimed to assess neonatal intensive care unit (NICU) policies related to toxicology screening and provision of MBM from THC-positive mothers. We hypothesized variation in policies exists across the nation and may be associated with state legalization status. Methods: Cross-sectional survey of U.S. NICU policies related to: (1) toxicology screening of mother-baby dyads and (2) MBM feeding limitations based on THC screening status. We assessed the impact of THC legalization status on the various MBM limitations. Results: Of 187 NICUs surveyed, 79% performed selective toxicology screening based on risk factors, clinical concerns, or provider discretion. Of those that specifically addressed THC exposure and MBM feeding policies, 60% had at least one limitation to MBM feeds, ranging from preventing any MBM feeding during NICU admission to limiting MBM until mother tested negative for THC. We found no significant association between state legalization status and MBM limitations. NICU and nursery policies differed in 33% of institutions. Conclusions: Substantial variation exists in NICU policies regarding toxicology screening and MBM limitations related to THC. These inconsistent policies are based not on THC legalization status but rather on the location of delivery. More research is needed on the effect of THC exposure on neonates, but we could limit inconsistent care by following current national medical organization guidelines of education and shared decision-making with mothers.

Introduction: Although exclusive breastfeeding is recommended for the first six months of life, many lactating individuals discontinue due to low milk supply, a condition sometimes referred to as chronic lactation insufficiency (CLI). Affecting an estimated 5-15% of lactating individuals, CLI can stem from both extrinsic factors (e.g., infant feeding challenges) and intrinsic ones (e.g., endocrine or metabolic disorders). This qualitative study explored the lived experiences of individuals with CLI and their interactions with healthcare providers (HCPs). Methods: In-depth, semi-structured interviews were conducted with 30 individuals who self-reported experiencing low milk supply, were 18 or older, and were members of the "IGT and Low Milk Supply Support Group" on Facebook, which has approximately 10,700 members. Data were analyzed using phronetic iterative analysis which is a cyclical, reflexive coding approach that emphasizes practical reasoning. Results: Participants reported significant challenges, including: (1) not being believed or taken seriously; (2) facing discrepancies between providers that led to fragmented care; and (3) experiencing a lack of knowledge from HCPs, including lactation consultants. Many described actively seeking a diagnosis and meaningful support but instead receiving inconsistent advice and little to no diagnostic insight into their condition. Conclusions: These findings highlight the urgent need for improved education and training among HCPs to address the complex realities of CLI. They also point to the importance of advancing personalized approaches to breastfeeding support and expanding research to determine causes and diagnostics for low milk supply. By centering patient voices, this study identifies critical gaps in care and communication that prevent effective support for those navigating CLI.

Background: Racial/Ethnic disparities in breastfeeding practices exist despite strong evidence for significant health benefits of breastfeeding for the mother-newborn dyad. Breastfeeding intentions are known to predict breastfeeding practices at hospital discharge and breastfeeding retention in the long term. Interventions during postpartum hospitalization can help mothers achieve breastfeeding intentions and reduce racial/ethnic gaps in breastfeeding on discharge. This study aims to identify racial/ethnic disparities in meeting intentions to exclusively breast milk feed (EBMF) on hospital discharge. Methods: This was a retrospective cohort study of mothers who intended to EBMF and their newborns delivered at term at a single academic medical center during 2022. The primary outcome was EBMF at discharge. Results: Participants included non-Hispanic Black (NHB) (n = 96), Hispanic (n = 97), and non-Hispanic White (NHW) (n = 955) mothers who intended to EBMF. Mothers who identified as NHB (40.6%) or Hispanic (64.9%) were significantly less likely to EBMF compared with NHW (87.5%) mothers (odds ratio [OR] = 0.14, 95%CI [0.08, 0.23] and OR = 0.37, 95%CI [0.22, 0.61], respectively) at newborn hospital discharge. Rurality, insurance type, gravidity, parity, gestational diabetes, and birth weight were not associated with breast feeding choice/practices at discharge, but increasing age was associated with an increased likelihood of EBMF (OR = 1.07, 95%CI [1.03, 1.11]), as was neonatal intensive care unit admission (OR = 2.93, 95%CI [1.18, 7.31]). Cesarean birth was associated with decreased likelihood of EBMF (OR = 0.57, 95%CI [0.38, 0.85]). Conclusion: Significant racial/ethnic disparities in EBMF at hospital discharge exist among those who intended to EBMF, which are not explained by differences in other examined covariates.

Background: Extended-release buprenorphine (XR BUP) is commonly used for individuals with opioid-use disorder (OUD), however, with limited experience in pregnancy. N-methyl-2-pyrrolidone (NMP), an excipient of monthly XR BUP formulations, is a developmental toxicant. No information is available on pharmacokinetics or breast milk transfer in lactating individuals receiving XR BUP. Methods: Samples of maternal plasma, infant plasma, and breast milk were collected from lactating individuals between 0 and 6 months postpartum receiving monthly XR BUP. All samples were analyzed for BUP and NMP concentrations using a validated liquid chromatography-tandem mass spectrometry assay. Results: Three lactating individuals provided a total of nine maternal plasma, six infant plasma, and five breast milk samples. Mean BUP concentrations were 6.0 ng/mL (standard deviation [SD] 1.6) in maternal plasma, 8.9 ng/mL (SD 6.6) in breast milk, and below the lower limit of quantitation for all infant plasma samples. We estimated the relative infant dose (RID) of BUP to be 1%. NMP was detectable in maternal plasma (mean 5.43 μg/mL, SD 4.56) and breast milk (mean 3.83 μg/mL, SD 5.07) only from samples measured between 1 and 5 hours after dosing. NMP was not detected in infant plasma. Conclusions: Among lactating individuals receiving XR BUP, BUP was present in low levels in maternal plasma (similar to nonlactating individuals on XR BUP) and breast milk of lactating individuals receiving XR BUP (similar to lactating individuals on sublingual BUP), resulting in a low RID. NMP passes into breast milk, however, was not present in infant plasma. Additional data are needed before definitive conclusions can be made.

Objective: Mother's own milk (MOM) sodium (Na) is an objective measure of secretory activation (SA), which is often delayed or impaired after preterm delivery. We sought to determine in pump-dependent mothers of preterm infants, impacts of maternal comorbidities on lactation outcomes using objective measures, including MOM Na, pumping frequency and MOM volumes for the first 14 postpartum days. Study Design: In this secondary analysis of four prospective cohorts, we examined outcomes using logistic and linear regression, survival analysis, and mediation and moderation sub-analyses. Results: A total of 143 mothers (57.3% Black, 30.8% Hispanic; 35.0% with hypertensive disorders of pregnancy [HDP]; 9.8% diabetic; 73.8% high body mass index [BMI]) delivered at 29.1 ± 2.8 weeks. Mothers pumped 4.7 ± 1.8 times/daily. Daily pumping frequency was a significant independent predictor of all modeled outcomes (p < 0.001 SA achievement, maintenance, and time to SA achievement; daily MOM volume; coming to volume [CTV; 500 mL/day]). 88.1% achieved SA by MOM Na ≤16 mM at postpartum day 5.6 ± 2.5. Only 41.3% of this subset continuously maintained SA until postpartum day 14. HDP was negatively associated with time to SA (p = 0.039). BMI values were negatively associated with MOM volume (p = 0.017) and CTV achievement (p = 0.02). Effects of daily pumping frequency were moderated by BMI (SA achievement and time to SA) and diabetes (CTV), with worse outcomes for higher BMI or diabetes despite similar pumping frequencies. Conclusion: Daily pumping frequency was the significant independent predictor for early lactation outcomes in a breast pump-dependent cohort of mothers of preterm infants. Further research on the interplay between modifiable and unmodifiable lactation risks in high-risk populations is needed.
