Expressed breast milk and maternal expression of breast milk for the prevention and treatment of neonatal hypoglycemia: a systematic review and meta-analysis
Bibliographic record
Abstract
BACKGROUND: Worldwide, many guidelines recommend the use of expressed breast milk (EBM) and maternal expression of breast milk for the prevention and treatment of neonatal hypoglycemia. However, the impact of both practices on neonatal hypoglycemia is unclear. This study aims to determine the effectiveness of EBM and maternal expression of breast milk in preventing and treating neonatal hypoglycemia. METHODS: We registered our review in PROSPERO (CRD42022328072). We systematically reviewed five databases and four clinical trial registries to identify randomized controlled trials (RCT), non-randomized studies of intervention (NRSI), and cohort studies that compared infants who received EBM to infants who did not, and similar study designs that compared infants whose mothers expressed breast milk to infants whose mothers did not. Two independent reviewers carried out screening, data extraction, and quality assessment. The quality of included RCT, NRSI, and cohort studies were respectively assessed with the Cochrane Risk of Bias 2, Risk Of Bias In Non-randomised Studies-of Interventions, and the Newcastle-Ottawa Scale tools. Results from studies on EBM were synthesized separately from those on maternal expression of breast milk. Meta-analysis was undertaken using Revman 5.4. and fixed-effect models. RESULTS: None of the ten included studies was specifically designed to determine the effect of EBM or maternal expression of breast milk on neonatal hypoglycemia. The effect of EBM on neonatal hypoglycemia was not estimable. There was no difference in the risk of hypoglycaemia among neonates whose mothers expressed breast milk compared to those whose mothers did not [RR (95%CI); one RCT: 0.92 (0.77, 1.10), high-certainty evidence; one cohort: 1.10 (0.74, 1.39), poor quality study]. CONCLUSIONS: There is insufficient evidence to determine the effectiveness of EBM for preventing or treating neonatal hypoglycemia. Limited data suggests maternal breast milk expression may not alter the risk of neonatal hypoglycemia. High-quality randomized controlled trials are needed to determine the effectiveness of EBM and maternal expression of breast milk for the prevention and treatment of neonatal hypoglycemia.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
