AI Article Synopsis
- Preterm birth is linked to a higher risk of respiratory issues like wheezing and asthma in children, prompting a review of early-life nutrition's impact on these outcomes.
- A scoping review analyzed nine studies, with mixed results: four indicated breastfeeding might protect against respiratory problems, while four did not establish a clear connection.
- The review highlights significant variability in study methods and results, indicating a need for more rigorous research to better understand how early nutrition affects respiratory health in preterm infants.
Article Abstract
Introduction: Preterm birth is a common early-life event that can lead to long-term consequences. The incidence of wheezing, asthma, and respiratory tract infections is higher in children born prematurely than in the general population. The purpose of this review was to synthesize the existing literature on the role of early-life nutrition in the later risk of respiratory morbidities.
Methods: A scoping review of the literature was performed by searching three online databases. Inclusion criteria were: infants born <37 GWk, comparing human milk versus any other type of milk feeding formulation. Our primary outcomes were wheezing or asthma or respiratory tract infections after discharge. Two authors independently screened the results and extracted study characteristics using a predefined charting form.
Results: Nine articles were included (eight cohort studies and one randomized trial). Four studies supported the protective effect of breastfeeding on wheezing or respiratory infections or both. Four studies did not confirm this association. One study confirmed the protective role of breastfeeding only on the subgroup of girls. There was a high heterogeneity among the included studies, in the type of milk feeding, outcomes, and age at follow-up.
Conclusions: The current evidence is conflicting. The high heterogeneity and methodological flaws could have influenced the results of the studies. Carefully designed studies are required to define the role of early-life nutrition among preterm infants on their long-term respiratory outcomes.

To determine the basis for perinatal nutritional mismatch causing metabolic dysfunction associated steatotic liver disease (MASLD) and diabetes mellitus, we examined adult phenotype, hepatic transcriptome, and pancreatic β-islet function. In prenatal caloric restricted rat with intrauterine growth restriction (IUGR) and postnatal exposure to high fat with fructose (HFhf) or high carbohydrate (RC), we investigated male and female IUGR-Hfhf and IUGR-RC, versus HFhf and CON offspring. Males more than females displayed adiposity, glucose intolerance, insulin resistance, hyperlipidemia, hepatomegaly with hepatic steatosis.

Background: Urine is an attractive biospecimen for nutritional status and population health surveys. It is an excellent non-invasive alternative to blood for appropriate biomarkers in young children and is suitable for home-based collection, enabling representative collections across a population. However, the bulk of literature in this population is restricted to collection in primary care settings.

Purpose Of Review: To review evidence supporting human umbilical cord mesenchymal stem cells (UC-MSC) as an innovative model system advancing obesity precision medicine.
Recent Findings: Obesity prevalence is increasing rapidly and exposures during fetal development can impact individual susceptibility to obesity. UC-MSCs exhibit heterogeneous phenotypes associated with maternal exposures and predictive of child cardiometabolic outcomes.

Increasing evidence suggests that carotenoids play an important role in visual and cognitive development during early life. This study aimed to depict the carotenoid profile in maternal/cord plasma and breast milk in three northern cities of China while investigating the association between dietary carotenoid intake and breast milk carotenoid levels. We enrolled 990 lactating mothers from three urban northern Chinese cities to collect breast milk (including colostrum, transitional milk, early mature milk, middle mature milk, and late mature milk).

Leveraging extensive multi-omics profiling (methylome, miRNome, transcriptome, proteins and metabolites) and a rich phenotypic characterization across two parts of Europe within the population-based Human Early Life Exposome project, we unravel the molecular landscape of childhood obesity and associated metabolic dysfunction. Our integrative analysis uncovers three clusters of children defined by specific multi-omics profiles, one of which characterized not only by higher adiposity but also by a high degree of metabolic complications.
