A multidisciplinary working group was established under the auspices of the Preterm Birth International Collaborative (Australasia Branch). The development process included a comprehensive literature review of databases, which identified 61 publications. Recommendations were formulated using the Grading of Recommendations, Assessment, Development and Evaluation system for evidence evaluation. A modified Delphi method was used to achieve consensus. The consensus establishes that neonatal LI presents with nonspecific gastrointestinal symptoms, requiring stool assessment for diagnosis. Screening tests include fecal reducing sugar or urinary galactose tests, and the diagnosis is confirmed through elimination testing while excluding mimics. Treatment prioritizes lactase-supplemented breastfeeding; formula-fed infants receive lactase or reduced-lactose formulas. Probiotics with β-galactosidase activity can be used as an adjuvant therapy, and evidence-based lactase preparations are recommended, particularly for preterm infants. Treatment duration should be individualized, with a general minimum of 2 weeks; however, the routine use of lactose-free formula to prevent LI in preterm infants is not recommended. This consensus provides practical evidence-based guidance to standardize the diagnosis and management of neonatal LI, aiming to reduce variation in practice and improve patient outcomes. It emphasizes the importance of maintaining breastfeeding while incorporating lactase supplementation and highlights the need for further high-quality research, particularly randomized controlled trials, to refine diagnostic criteria and therapeutic strategies for preterm and very preterm infants. The recommendations are intended to support clinicians in making informed decisions while promoting family-centered care.</p><p><strong>Trial registration: </strong>International Practice Guidelines Registry Platform (PREPARE-2024CN606).</p>","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"4 1","pages":"e70044"},"PeriodicalIF":0.0,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13097654/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147794692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These conditions are defined by poor responsiveness to current therapeutic interventions and pose substantial clinical challenges, primarily due to their high morbidity and mortality rates. This review synthesizes the current understanding of the molecular mechanisms underlying RLDs and explores promising therapeutic strategies. A core feature of RLD pathogenesis is the disruption of alveolar microenvironmental homeostasis, which triggers a bidirectional vicious cycle between structural damage and disease progression. This homeostatic collapse is driven by interconnected pathological networks-including oxidative stress coupled with mitochondrial dysfunction, inflammatory immune dysregulation, and mechanical stress-induced extracellular matrix (ECM) remodeling-all of which are elaborated in this review. Collectively, these pathological processes contribute to therapeutic resistance. Based on these mechanistic insights, potential therapeutic approaches are discussed, such as antioxidant therapies (e.g., the mitochondria-targeted antioxidant Mitoquinone mesylate [MitoQ]) and antifibrotic agents (e.g., pirfenidone, nintedanib, as well as emerging strategies targeting Wnt pathway modulation). Additionally, the critical significance of early diagnosis and personalized precision medicine is emphasized. Future research should focus on a deeper characterization of the dynamic alterations within the alveolar microenvironment under pathological conditions, with the aim of developing more precise diagnostic tools and targeted therapeutic strategies. Ultimately, the therapeutic goal for RLDs should shift from mere symptom management to achieving pathological reversal.</p>","PeriodicalId":520221,"journal":{"name":"Pediatric discovery","volume":"4 1","pages":"e70040"},"PeriodicalIF":0.0,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13097683/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147794731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence indicates that aberrant maternal metabolomic profiles are associated with CHD, but it is uncertain whether such an association exists in umbilical cord blood. This study aimed to measure the metabolome shifts in monozygotic (MZ) twins discordant for CHD and, if present, identify the altered metabolites and metabolic pathways. Umbilical cord blood from three pairs of MZ twins discordant for CHD, identified through the prospective, population-based longitudinal twin study (LoTiS), was subjected to ultrahigh-performance liquid chromatography coupled with mass spectrometry (UHPLC-MS/MS) based metabolomic analysis. Orthogonal partial least square-discriminate analysis (OPLS-DA) and random forest (RF) analysis were used to determine differences in metabolic profiles and individual metabolites. In univariate analysis, two specific metabolites were identified in the umbilical cord blood of CHD cases compared to their MZ twins without complications. After the paired-sample <i>t</i>-test, four differentially expressed metabolites (DEMs) were identified, three of which were closely related to fatty acids and their metabolism. Enrichment pathway analysis revealed dysregulation of various metabolic pathways, including glucose metabolism, lipid metabolism, and amino acid metabolism pathways, in MZ twins with CHD compared to their healthy counterparts. The results demonstrated that the metabolomic signature of umbilical cord blood in CHD differs from that of their healthy MZ co-twins, and the revelation of associated metabolites and pathways provide preliminary clues for generating hypotheses about the metabolic correlates of CHD predisposition.
