Gut microbiota and metabolomic alterations in newborns of mothers with gestational diabetes mellitus.
Article in Clinical and experimental pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGestational diabetes mellitus (GDM) is a common complication of pregnancy associated with various perinatal risks in mothers and heightened risks of long-term obesity and metabolic syndrome in their children. Understanding the effect of GDM on infant health is crucial. Infant gut colonization has generated significant interest owing to its profound impact on health and potential role in later disease development. PURPOSE: Here we conducted a thorough analysis of the microbiota and metabolome of neonatal meconium to understand how GDM in mothers affects microbial colonization in the early lives of their offspring.
methodsThis study included 49 healthy-term neonates born to mothers with GDM (n=29) and normoglycemic mothers (n=20) between March 2022 and February 2023 at Chang Gung Memorial Hospital (Linkou branch). Fecal samples were collected in sterilized containers before the infants reached 5 days of age. To analyze the meconium microbiota, 16S rRNA gene sequencing was performed, and proton nuclear magnetic resonance was used to examine the metabolome.
resultsNeonates born to mothers with diet-controlled GDM exhibited a notable decrease in α-diversity and a shift in β-diversity compared to those born to normoglycemic mothers. A functional analysis revealed increased peroxisome proliferator-activated receptor and adipocytokine signaling pathway activation in the GDM group. Metabolomic analysis revealed significant changes in the fumarate and succinate levels, indicating metabolic shifts associated with maternal GDM.
conclusionThese findings highlight the potential effects of pregnancy-related complications on the establishment of gut bacteria in neonates. Further comprehensive studies are required to understand the long-term implications of these microbial changes on infant health.
