Background: Enteral high-dose docosahexaenoic acid (DHA) may be required for neurodevelopment, including cognition, of extremely preterm infants. High-level summative evidence is lacking.

Objectives: This study aims to examine associations between enteral high-dose DHA during the neonatal period and neurodevelopment in infants born ≤29 wk of gestation.

This paper describes the methods for the development and implementation of the Sino-Canadian Healthy Life Trajectories Initiative (SCHeLTI) intervention, part of a World Health Organization-supported effort to prevent childhood obesity through four international randomized controlled trials. SCHeLTI is a multi-center, cluster-randomized trial in Shanghai, supporting 4500 families from preconception through the child's fifth year. This Community-Family-Mother-Child intervention includes coordinated components such as Healthy Conversation sessions, nutrition consultations, breastfeeding support, an obesity clinic, and educational courses tailored to key reproductive and developmental stages and risk profiles.

PurposeLimited data are available on the cardiorespiratory and muscle fitness of children with acute lymphoblastic leukemia (ALL) during chemotherapy. This pilot study evaluated the safety of testing the cardiorespiratory and muscle fitness of two children with ALL at different risk levels in early chem treatment.MethodsTwo girls with low- and high-risk B-cell ALL (DFCI-16-001) took part in two test sessions: T1 (induction, consolidation 1A/C) and T2 (consolidation 2).

Background: Neonatal supplementation with high-dose docosahexaenoic acid (DHA) omega-3 may benefit neurodevelopment in very preterm infants, but concerns remain regarding a potential increased risk and severity of bronchopulmonary dysplasia (BPD). However, the interpretation of evidence on the effect of DHA on severe BPD is challenging because of the heterogeneity in the BPD definitions used across trials.

Objectives: This study aims to determine whether, compared with placebo, neonatal enteral supplementation with high-dose DHA, mimicking placental transfer, is associated with severe BPD in very preterm infants using an individual participant data meta-analysis of randomized controlled trials (RCTs).

Unlabelled: To explore whether prenatal conditions (i.e. chorioamnionitis, preeclampsia or small-for-gestational age (SGA)) affect the very preterm infant's response to docosahexaenoic acid (DHA) on bronchopulmonary dysplasia (BPD), according to mode of delivery, an independent factor shown to modulate this association.

Article Synopsis
  • Docosahexaenoic acid (DHA), an important omega-3 fatty acid for brain development, was studied to see if high-dose supplementation during the neonatal period could enhance behavioral functioning in very preterm children by age 5.
  • In a multicenter randomized controlled trial, 177 children were assessed at 5 years, with 132 completing neurodevelopmental evaluations.
  • Results showed no significant improvement in behavioral functioning or secondary outcomes for those who received DHA compared to a placebo, indicating that high-dose DHA did not have the expected positive effects.

  • Maternal antenatal depression can negatively affect perinatal outcomes, but prior studies mainly look at later pregnancy symptoms and show inconsistent results.
  • This study involved 2,053 participants using the Edinburgh Postnatal Depression Scale to track depressive symptoms across all trimesters, examining their impact on infant growth within the first year.
  • Results indicated that higher depressive scores in the first and second trimesters were linked to larger birth weight (macrosomia), while higher scores in the third trimester increased risks for preterm birth and low birth weight, emphasizing the need for depression screening early in pregnancy.

Objective: Endocannabinoids and their -acyl-ethanolamines (NAEs) and 2monoacyl-glycerols (2-MAGs) congeners are involved in the central and peripheral regulation of energy homeostasis, they are present in human milk and are associated with obesity. Infants exposed to gestational diabetes mellitus (GDM) are more likely to develop obesity. The objective of this cross-sectional study is to compare the profile of eCBome mediators in milk of women with gestational diabetes (GDM+) and without (GDM-) and to assess the association with offspring growth.

Article Synopsis
  • This study investigates the impact of high-dose docosahexaenoic acid (DHA) supplementation on the risk of severe bronchopulmonary dysplasia (BPD) in very preterm infants born at less than 29 weeks of gestation.
  • It will employ an individual participant data (IPD) meta-analysis of randomized controlled trials, assessing severe BPD outcomes at 36 weeks' postmenstrual age while considering various neonatal morbidities.
  • Ethical approval was secured for each trial, and informed consent was obtained from parents, ensuring proper collaboration and data sharing among participating institutions.

Metrics of retinal image quality predict optimal refractive corrections and correlate with visual performance. To date, they do not predict absolutely the relative change in visual performance when aberrations change and therefore need to be a-posteriori rescaled to match relative measurements. Here we demonstrate that a recently proposed metric can be used to predict, in an absolute manner, changes in contrast sensitivity measurements with Sloan letters when aberrations change.

Oxylipins are derived from enzymatic and non-enzymatic oxidation of n-3 and n-6 long-chain polyunsaturated fatty acids. They are known to be involved in inflammatory processes. The aim of this study was to describe the breast milk oxylipin profile following a docosahexaenoic acid (DHA) supplementation of mothers of preterm infants.

Objective: To determine how neonatal growth velocity affects the association between birth weight and neurodevelopmental outcomes in infants born preterm.

Study Design: This study is a secondary analysis of the Maternal Omega-3 Supplementation to Reduce Bronchopulmonary Dysplasia in Very Preterm Infants (MOBYDIck) randomized multicenter trial conducted in breastfed infants born at <29 weeks of gestation, whose mothers were supplemented with docosahexaenoic acid or placebo during the neonatal period. Neurodevelopmental outcomes were assessed at 18-22 months of corrected age using the Bayley-III cognitive and language composite scores.

Aim: To assess whether small-for-gestational-age (SGA) - an indicator of poor fetal growth, may affect metabolic health biomarkers in infancy and explore the predictors.

Methods: This was a nested matched (1:2) prospective observational study of 65 SGA (birth weight < 10th percentile) and 130 optimal-for-gestational-age (OGA, birth weight 25th-75th percentiles, control) infants in the 3D birth cohort with subjects recruited in Canada from 1 May 2010 to 31 August 2012. The outcomes included homeostasis model assessment of insulin resistance (HOMA-IR) and beta-cell function (HOMA-β), circulating leptin and adiponectin concentrations at age 2 years.

Importance: High-dose docosahexaenoic acid (DHA), a long-chain polyunsaturated fatty acid, may affect the risk of bronchopulmonary dysplasia (BPD). However, high-level summative evidence supporting such clinical association in very preterm infants is lacking.

Objective: To examine the association between enteral supplementation with high-dose DHA during the neonatal period and the risk of BPD in preterm infants born at less than 29 weeks' gestation.

Gestational diabetes mellitus (GDM) is known to affect human milk composition. Aims of this study were to compare macronutrient and energy content of human milk of women with (GDM) and without GDM (GDM), to assess the association between maternal health and human milk macronutrient and energy content and association between human milk macronutrient and energy content and infant growth. Two months after delivery, hindmilk samples were collected.
