Question: Do gut microbiota differ between patients with Hirschsprung disease (HSCR) and healthy children, and can specific bacterial taxa predict postoperative HSCRassociated enterocolitis (HAEC)?
Finding: Patients with HSCR showed gut dysbiosis with reduced diversity. Postoperative microbial changes included increased alpha diversity. Certain taxa, such as Eubacterium and Collinsella, were associated with recovery or HAEC.
Meaning: Distinct microbial signatures may help identify HAEC risk and guide microbiota-based strategies to improve outcomes.

Question: Can probiotic BLa80 bring long-term benefits to the health of young children?
Finding: This trial demonstrated that the daily administration of s BLa80 at 5×109 colony-forming units for 3 months in children can reduce the risk of eczema, upper respiratory tract infections, and acute tracheitis/bronchitis as well as beneficially improve the gut microbiome without any adverse effect.
Meaning: Bla80 can bring definite health benefits to young children.

Question: Does the gut microbiota differ between very low birth weight (VLBW) infants with versus without bronchopulmonary dysplasia (BPD)?
Finding: Common respiratory pathogens were notably elevated in the BPD group, whereas anaerobic and butyrate-producing taxa, key components of postbiotics, were dominant in the non-BPD group.
Meaning: In gut-lung communication, the interplay between the intestinal and respiratory systems may implicate pro- and postbiotics in VLBW infants with BPD.
