Aim This paper summarises published evidence on the use of recorded music in high‐risk infants to reduce stress and improve neurodevelopment, forming recommendations for proposed clinical applications in neonatal intensive care units. Methods We searched two comprehensive library catalogues and two databases for articles evaluating the impact of recorded music interventions on hospitalised preterm infants. Original and review papers published in English in the 10 years prior to this search were selected if the study included a component of recorded music interventions. Results Most original studies (80.95%) and all literature reviews (100%) reported positive effects of recorded music interventions for preterm infants, primarily in the short term. No negative effects were reported. Evidence is emerging regarding the neurobiological mechanisms of recorded music on longer‐term effects on preterm infant neurodevelopment. Clinical applications were suggested drawing upon available evidence. Due to generally small sample sizes and variability in study design, unanswered questions remain. Conclusion Carefully designed recorded music interventions appear to be safe, feasible and effective in reducing stress and improving neurodevelopment of hospitalised infants. Additional rigorous, well‐powered trials with relevant outcomes are needed to further refine specific elements for recorded music interventions to better inform practice.

Animal studies have demonstrated the therapeutic potential of polyphenol-rich pomegranate juice. We recently reported altered white matter microstructure and functional connectivity in the infant brain following in utero pomegranate juice exposure in pregnancies with intrauterine growth restriction (IUGR). This double-blind exploratory randomized controlled trial further investigates the impact of maternal pomegranate juice intake on brain structure and injury in a second cohort of IUGR pregnancies diagnosed at 24–34 weeks’ gestation. Ninety-nine mothers and their eligible fetuses (n = 103) were recruited from Brigham and Women’s Hospital and randomly assigned to 8 oz pomegranate (n = 56) or placebo (n = 47) juice to be consumed daily from enrollment to delivery. A subset of participants underwent fetal echocardiogram after 2 weeks on juice with no evidence of ductal constriction. 57 infants (n = 26 pomegranate, n = 31 placebo) underwent term-equivalent MRI for assessment of brain injury, volumes and white matter diffusion. No significant group differences were found in brain volumes or white matter microstructure; however, infants whose mothers consumed pomegranate juice demonstrated lower risk for brain injury, including any white or cortical grey matter injury compared to placebo. These preliminary findings suggest pomegranate juice may be a safe in utero neuroprotectant in pregnancies with known IUGR warranting continued investigation.Clinical trial registration: NCT04394910, https://clinicaltrials.gov/ct2/show/NCT04394910, Registered May 20, 2020, initial participant enrollment January 16, 2016.
