GLP-1s linked to nutritional deficiencies in children

Children prescribed GLP-1 medications for weight loss, prediabetes, or type 2 diabetes are at risk for nutritional deficiencies – diagnosed in nearly one in six patients (16.8%) within the first year – according to a new study published in the journal Childhood Obesity.

First foods bring an early functional shift in the infant gut microbiome

Researchers analyzing paired gut microbiome samples from 125 Irish infants found that complementary feeding was associated with early changes in microbial composition and metabolic potential, including an increased capacity for complex carbohydrate metabolism. Breastfeeding duration was more closely associated with microbial community development than the timing of solid-food introduction, while formula-fed infants showed more extensive functional pathway changes after solids were introduced.

Sudden unexpected infant deaths drive widening Black-white mortality gap

After years of declines in sudden unexpected infant deaths (SUID), rates have been ticking up again, particularly among babies born to Black mothers, new research shows.

Early treatment may improve outcomes in Shwachman-Diamond syndrome

More than 90% of children born with the rare bone marrow condition called Shwachman-Diamond Syndrome (SDS) survive beyond age 20. But fewer than 30% live beyond age 50.

A child's gut microbiome may offer early clues to type 1 diabetes risk

Researchers tracking 887 children at high genetic risk of type 1 diabetes identified three distinct patterns of gut microbiome maturation during early childhood. One pattern was associated with substantially higher risk of islet autoantibody seroconversion or type 1 diabetes, while host genetic background altered the risk associated with another pattern.

Brain organoids reveal new clues for childhood epilepsy treatments

Tiny, year-old human brain organoids that mimic the brain of a newborn are providing new clues to potential treatments for a leading genetic cause of childhood epilepsy that typically manifests as the brain matures shortly after birth.

Overheard adult speech shapes word learning in young children

Overhearable speech (speech that may occur when caregivers are talking to each other in the child's presence), constitutes over half of children's language exposure, but its role in language development remains underexplored.

Dietary changes can prevent Hirschsprung disease symptoms

A multi-institutional study led by researchers at Children's Hospital of Philadelphia (CHOP) discovered for the first time that dietary interventions might prevent inflammatory symptoms associated with Hirschsprung disease, a bowel motility disorder.

Early childhood BMI trajectories predict later cardiometabolic health risks

Childhood obesity predicts later cardiometabolic disease, but single-time weight measures may miss dynamic growth information.

Study finds no causal link between prenatal paracetamol and neurodevelopmental disorders

Various studies over the years have linked prenatal use of the pain reliever paracetamol (acetaminophen) with neurodevelopmental disorders such as autism and attention-deficit/hyperactivity disorder (ADHD) in children, but many of the studies were small, poorly designed, or found only weak associations

Common chemical exposures in pregnancy may be linked to early attention and memory

Researchers examined whether prenatal exposure to aromatic amines and cotinine was associated with attention, processing speed, and memory in 250 infants assessed at 7.5 months. The study found mixed patterns across cognitive measures, with several estimates suggesting poorer attention or memory but carrying substantial statistical uncertainty.

Could a parent’s hospital job shape a child’s nasal microbiome?

A pilot study of 37 families found that children with healthcare-worker parents had lower nasal microbial diversity, with the largest differences among children whose two parents worked in healthcare. Porphyromonas was significantly less abundant, while Neisseria showed a similar non-significant pattern, but the cross-sectional study cannot establish causality or determine whether these microbiota differences affect health.

Why scientists still cannot say how much plastic infants are actually consuming

A systematic review of 22 primary studies and four reviews found plastic-derived contaminants across infant foods and feeding equipment, but major differences in sampling, analytical methods, and quality control made exposure estimates difficult to compare. The authors found substantial evidence gaps for nanoplastics and oligomers and concluded that better-standardized exposure assessment is needed before infant health risks can be reliably evaluated.

Children of single mothers by choice show favorable birth outcomes

The children of single mothers who conceive through medically assisted reproduction (MAR) have similar outcomes to babies of partnered mothers who had conceived naturally, a UCL-led study has found.

Ketamine-related bladder problems reported among young teenagers

Non-prescribed ketamine use may start at the age of 13, suggest data from a UK clinic dedicated to the treatment of bladder problems associated with misuse of the drug and published in a clinical letter in the Archives of Disease in Childhood.

A hidden measles signal may reveal how large the next outbreak could be

Researchers used historical measles surveillance and demographic data from pre-vaccination England and Wales to reconstruct how the susceptible population changed between epidemics. Their model linked susceptibility at the start of an epidemic year with the magnitude of the following outbreak, pointing to a potential route for one-year-ahead forecasting that requires further development for modern surveillance settings.
