Reduced crying in term infants fed high beta-palmitate formula: a double-blind randomized clinical trial

BACKGROUND: Beta-palmitate (sn-2 palmitate) mimics human milk fat, enabling easier digestion. Therefore, we hypothesized that infants consuming high beta-palmitate formula would have more frequent, softer stools and reduced crying compared to infants consuming low beta-palmitate formula. METHODS: Formula-fed infants were randomly assigned to receive either (1) formula with high beta-palmitate (HBP, n = 21) or (2) regular formula with a standard vegetable oil mix (LBP, n = 21). A matched group of breastfed infants served as a reference (BF, n = 21). Crying and stool characteristics data were recorded by the parents for 3 days before the 6- and 12-week visits. RESULTS: We found no significant differences in the stool frequency or consistency between the two formula groups. The percentage of crying infants in the LBP group was significantly higher than that in the HBP and BF groups during the evening at 6 weeks (88.2% vs. 56.3% and 55.6%, p < 0.05) and during the afternoon at 12 weeks (91.7% vs. 50.0% and 40%, p < 0.05). The infants fed HBP had significantly shorter crying durations when compared with infants fed LBP formula (14.90 ± 3.85 vs.63.96 ± 21.76 min/day, respectively; p = 0.047). CONCLUSIONS: Our study indicates that consumption of a high beta-palmitate formula affects infant crying patterns during the first weeks of life. Comparable to breastfeeding, it reduced crying duration and frequency, primarily during the afternoon and evening hours, thereby improving the well-being of formula-fed infants and their parents.

Music therapy for preterm infants and their parents:A cluster-randomized controlled trial protocol

Music therapy (MT) interventions and skin-to-skin care (SSC) both aim to address the varied needs of preterm infants, including sensory regulation and stress reduction, inclusion of parents in their infant’s care, support of parents’ emotional state, and enhancing the parent-infant attachment process. Few studies have investigated the combination of both modalities through randomized controlled trials. Evidence of longer-term effects is missing. This article presents a study protocol that will investigate the effects of combined family-centered MT intervention and SSC on preterm-infants’ autonomic nervous system (ANS) stability, parental anxiety levels, and parent-infant attachment quality. 12 clusters with a total of 72 preterm infants, with their parents, will be randomized to one of two conditions: MT combined with SSC or SSC alone. Each parent-“infant dyad will participate in 3 sessions (2 in the hospital and a 3-month follow-up). The primary outcome of preterm infants’ ANS stability will be measured by the high frequency power of their heart rate variability. Secondary outcomes will be physiological measures and behavioral states in infants and anxiety and attachment levels of parents. This trial will provide important, evidence-based knowledge on the use of the “First Sounds: Rhythm, Breath, and Lullaby” model of MT in neonatal care, through an intervention that is in line with the Newborn Individualized Developmental Care and Assessment Program model for supportive developmental care of preterm infants and their parents. Ethical approval (no. 0283-15) was granted from the local Institutional Review Board in April 2017. This trial is registered in ClinicalTrials.gov, NCT03023267

Nutrição precoce de neonatos prematuros estáveis e pequenos para a idade gestacional: um ensaio clínico randomizado

OBJETIVO: Examinar o efeito da nutrição precoce sobre o tempo para atingir a nutrição completa em neonatos prematuros (PIG) estáveis pequenos para a idade gestacional. MÉTODO: Os neonatos prematuros com idade gestacional inferior a 37 semanas e peso ao nascer inferior a 10% foram alocados aleatoriamente para um regime de nutrição precoce (nas primeiras 24 horas de vida) ou tardia (após as primeiras 24 horas de vida). Todos os neonatos apresentaram uma evidência intrauterina de fluxo diastólico reverso ou ausente. Os neonatos incapazes de iniciar uma nutrição precoce foram excluídos. O tempo para a alimentação completa, a progressão da nutrição e morbidez correspondente foram comparados. A eletrogastrografia (EGG) foi utilizada para mensurar a motilidade gástrica pré e pós-prandial no segundo e no sétimo dias após o início da nutrição. RESULTADOS: Foram incluídos 60 neonatos no estudo, sendo 30 em cada grupo. Os neonatos incluídos no regime de nutrição precoce atingiram a nutrição enteral completa antes dos neonatos do grupo de controle (98±80-157 em comparação a 172±1 23-261 horas de idade, respectivamente; p = 0,004) e recebiam alta hospitalar antes (p = 0,04). Nenhuma enterocolite necrosante (ECN) foi comprovada em ambos os grupos de estudo. A motilidade gástrica melhorou no sétimo dia após o início da nutrição em ambos os grupos de estudo, sem diferença entre eles. CONCLUSÕES: Os neonatos prematuros PIG estáveis em regime de nutrição precoce atingiram alimentação enteral completa e receberam alta hospitalar significativamente antes que aqueles em regime de nutrição tardio, sem morbidez excedente

Vitamin D Levels in Pregnant Women Do Not Affect Neonatal Bone Strength

Vitamin D plays a key role in regulating calcium and phosphate metabolism. However, whether maternal vitamin D levels affect fetal bone strength is unclear. This study assessed correlations between maternal 25(OH)D status and neonatal bone strength 25(OH)D levels, these were measured in the maternal and infant cord blood of 81 mother&ndash;infant dyads. Bone strength was measured using a quantitative ultrasound (QUS) of tibial bone speed of sound (SOS). Maternal vitamin D intake, medical history and lifestyle were evaluated from questionnaires. Maternal 25(OH)D levels were deficient (&lt;25 nmol/L) in 24.7%, insufficient (25&ndash;50 nmol/L) in 37% and sufficient (&gt;50 nmol/L) in 38.3%. The maternal and cord blood 25(OH)D levels correlated (r = 0.85, p &lt; 0.001). Cord blood levels (57.9 &plusmn; 33.5 nmol/L) were higher than the maternal blood levels (46.3 &plusmn; 23.2: p &lt; 0.001). The mean SOS was 3042 &plusmn; 130 m/s. The neonatal SOS and 25(OH)D levels were not correlated. The mean bone SOS levels were comparable in the three maternal and cord blood 25(OH)D groups. No correlation was found between the maternal 25(OH)D levels and the neonatal anthropometrics. Although the 25(OH)D levels were higher in Jewish mothers than they were in Muslim mothers (51.1 &plusmn; 22.6 nmol/L vs. 24 &plusmn; 14.7 nmol/L, respectively: p = 0.002) and in those who took supplemental vitamin D, the bone SOS levels were comparable. In conclusion, maternal vitamin D levels correlate with cord levels but do not affect bone strength or growth parameters

Regional Splanchnic Oxygenation during Continuous versus Bolus Feeding among Stable Preterm Infants

Introduction: There is no agreement regarding the best method for tube-feeding preterm infants. Few studies, to date, have evaluated the influence of different methods of enteral feeding on intestinal oxygenation. The use of near-infrared spectroscopy (NIRS) has permitted the noninvasive measurement of splanchnic regional oxygenation (rSO2S) in different clinical conditions. The aim of this prospective, single-center study was to compare rSO2S during continuous versus bolus feeding among stable preterm infants. Methods: Twenty-one preterm infants, less than 32 weeks gestation and appropriate for gestational age, were enrolled. All infants were clinically stable and on full tube feedings. Each infant received a bolus feeding initially (20 min duration), and after 3 h, a continuous feeding (5 h duration). Infants were evaluated 30 min before and 30 min after the bolus and continuous feedings. The regional splanchnic saturation (rSO2S) was measured using near-infrared spectroscopy (NIRS) technology and systemic saturation was measured with pulse oximetry. From these measurements, we calculated the splanchnic fractional oxygen extraction ratio (FOES) for each of the four intervals. Results: rSO2S decreased after continuous vs. bolus feeding (p = 0.025), while there was a trend toward decreased SaO2 after bolus feeding (p = 0.055). The FOES, which reflects intestinal oxygen extraction, was not affected by the feeding mode (p = 0.129). Discussion/Conclusion: Continuous vs. bolus feeding decreases rSO2S but does not affect oxygen extraction by intestinal tissue; after bolus feeding there was a trend towards decreased systemic saturation
