1 · What the graph read from it

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.

Abstract

backgroundHuman breast milk (HBM), which contains an abundant supply of exosomes, is known to prevent necrotizing enterocolitis (NEC). Preterm infants are commonly given pasteurized donor milk when HBM is unavailable. However, pasteurization can disrupt its components. This study investigates the effects of both raw and pasteurized HBM-derived exosomes on intestinal inflammation.

methodsHBM exosomes were isolated and characterized by positive CD63 and negative calnexin markers from western blot, nanoparticle tracking analysis and transmission electron microscopy. Mouse intestine organoids were established and treated with exosomes from raw or pasteurized HBM in healthy and injury conditions. Following ethical approval (#44032), mice pups were randomly assigned to (1) breastfed control; (2) NEC; (3) NEC receiving raw HBM exosomes; (4) NEC receiving pasteurized HBM exosomes. NEC was induced by hypoxia, gavage feeding and lipopolysaccharide (LPS). Ileum was evaluated. Data were analyzed using one-way ANOVA with Bonferroni post-test.

resultsBoth raw and pasteurized HBM exosomes decreased inflammation in hypoxia and LPS-treated organoids compared to control. In vivo, NEC-induced mucosal injury, inflammation and mucous production were improved by raw and pasteurized HBM-derived exosomes.

conclusionsExosomes derived from raw and pasteurized HBM equally reduced intestinal damage. Exosome administration in clinical practice requires further investigation.
