Metagenomic profile of the fecal microbiome of preterm infants consuming mother's own milk with bovine milk-based fortifier or infant formula: a cross-sectional study.

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
backgroundPreterm (PT) infants harbor a different gut microbiome than full-term infants. Multiple factors affect gut microbial colonization of PT infants, including low gestational age, high rates of Cesarean section, exposure to antibiotics, and diet. Human milk, whether it's mother's own milk (MOM) or donor human milk, is the preferred feeding mode for PT infants but needs to be fortified to achieve adequate nutrient content. Infant formulas are introduced at later stages if human milk is insufficient or unavailable. How these dietary exposures affect the gut microbiome of PT infants is poorly understood.
objectivesThe goal of this study was to evaluate the metagenomic potential of the fecal microbiome of PT infants consuming MOM with bovine milk-based fortifier compared with PT formula alone.
methodsForty-two stool samples, from 27 infants consuming MOM or formula (21 samples in each group) were included. Twelve infants had repeated sampling (2-3 samples). Shotgun genomic DNA sequencing was performed and analyzed using MetaPhlAn and HUMAnN2. Multivariate regression analysis, adjusting by the repeated sampling, was used to identify the features that differed between PT infants consuming MOM compared with formula.
resultsThe primary function of the fecal microbiome of PT infants was characterized by a high abundance of biosynthesis pathways. A set of core features was identified; these belonged to pathways for amino acid metabolism and vitamin K-2 biosynthesis. Five pathways significantly differed between the MOM and formula group. Pathways for fatty acid and carbohydrate degradation were significantly higher in the MOM group. Taxonomically, members of the phylum Actinobacteria and the genus Bifidobacterium were higher in PT infants exposed to MOM.
conclusionsThis study provides insight into the influence of feeding MOM compared with infant formula on the structure and function of the fecal microbiome of PT infants.
