ABSTRACT

Background: To prevent postoperative complications, delayed oral feeding (DOF) remains a common model of care following pediatric intestinal anastomosis surgery; however, early oral feeding (EOF) has been shown to be safe and effective in reducing the incidence of complications and fast recovery after pediatric surgery. Unfortunately, the evidence in support of EOF after intestinal anastomosis (IA) in infants is insufficient. Therefore, this study was primarily designed to evaluate the safety and efficacy of EOF. In addition, the current status of EOF application and associated factors that favor or deter EOF implementation were also assessed. Methods: A total of 898 infants were divided into two groups (EOF group, n = 182; DOF group, n = 716), and the clinical characteristics were collected to identify the factors associated with EOF in infants. Complications and recovery were also compared to define the safety and efficacy after balancing the baseline data by propensity score matching (PSM) (EOF group, n = 179; DOF group, n = 319). Results: The total EOF rate in infants with IA was 20.3%. Multivariate logistic regression revealed significant differences in the EOF rates based on IA site and weight at the time of surgery (OR = 0.652, 95% CI: 0.542-0.784, p < 0.001) and (OR = 1.188, 95% CI: 1.036-1.362, p = 0.013), respectively. The duration of total parenteral nutrition (TPN), parenteral nutrition (PN), and postoperative hospital stay were significantly shorter in the EOF group than the DOF group [2.0 (1.0, 2.0) d vs. 5.0 (3.0, 6.0) d; 6.0 (5.0, 8.0) d vs. 8.0 (6.0, 11.0) d; 10.0 (7.0, 14.0) d vs. 12.0 (9.0, 15.0) d, all p < 0.001]. The rates of abdominal distension and vomiting in the EOF group were significantly higher than the DOF group (17.9% vs. 7.2%, p < 0.001; 7.8% vs. 2.5%, p = 0.006); however, no differences were found in failure to initial OF, diarrhea, hematochezia, and anastomotic leakage between the two groups (p > 0.05). Conclusion: The overall rate of EOF in infants following IA was low, and the sites of anastomosis and weight at surgery were two factors associated with EOF. Nevertheless, performing EOF in infants after IA was safe and effective, reduced PN usage, shortened the hospital stay, and did not increase the rate of severe complications.Clinical Trial Registration: ClinicalTrails.gov, identifier NCT04464057.

ABSTRACT

BACKGROUND: Evidence supports an association between cholestatic liver disease and changes in microbiome composition. Nevertheless, the identification of this special type of biliary atresia from non-biliary atresia cholestasis is still a major clinical difficulty. The purpose of this study is to compare the differences in the composition of gut microbiome between infants with biliary atresia and infant with non-biliary atrestic cholestasis, to find new ways to identify and diagnose these two diseases early, to understand the influence of the presence or absence of bile on the composition of the gut microbiome in infants with cholestasis. METHODS: Using 16S rDNA gene sequencing technology to analyze the intestinal flora of the participants. RESULTS: In terms of diversity, there is an obvious structural separation in the intestinal microbiota of the BA group and the CD group, and this structural separation also exists in the comparison between the two groups before surgery. Taxonomic analysis demonstrated that the two groups showed an increase in Proteobacteria and Firmicutes before surgery, and the relative abundance of potential pathogens such as Shigella, Streptococcus, Klebsiella, etc. increased, potential probiotics such as Bifidobacteria and Lactobacillus decreased, but the relative abundance of each genus was different between groups. It was found that Enterococcus, Ralstonia, Nitriliruptoraceae, etc. were differentially enriched in the BA group, the CD group are mainly enriched in Veillonella, Clostridium_sensu_stricto_1 and Lactobacillus. Functional analysis of the groups showed that the BA group mainly focused on the processes of energy release processes, and the CD group mainly focused on the biosynthesis of amino-acids to consume energy. CONCLUSIONS: The composition of intestinal flora is different between biliary atresia and non-biliary atretic cholestasis. Enterococcus, Ralstonia, etc. may become biomarkers for the identification and diagnosis of both.

ABSTRACT

OBJECTIVES: This study aims to investigate the role of demethylase ALKBH5 mediated demethylation of TAGLN mRNA in the occurrence of Hirschsprung's disease (HSCR), and to clarify how ALKBH5 reduces the m6A level of TAGLN mRNA and inhibits its degradation, thereby inhibiting the proliferation and migration of neural crest cells, and potentially contributing to the occurrence of HSCR. MATERIAL AND METHODS: Quantitative real-time PCR (qRT-PCR) and Western-Blot (WB) were conducted to test the expression level of ALKBH5 and TAGLN genes. Cell function assays were adopted to detect cell phenotypes. The qRT-PCR and methylated RNA immunoprecipitation (MeRIP-qPCR) were used to test the regulation of TAGLN by ALKBH5. RESULTS: 1. Compared with control intestinal tissue, the expression level of TAGLN and ALKBH5 in the aganglionic intestinal tissue of HSCR is increased. 2. The MeRIP-PCR and dualluciferase report confirmed that ALKBH5 could bind to m6A sites of TAGLN mRNA and reduce the m6A level of TAGLN mRNA. 3. In vitro cell experiments confirmed that overexpression of ALKBH5 can inhibit the degradation of TAGLN mRNA, increase the expression of TAGLN, thereby inhibiting cell proliferation and migration. 4. A zebrafish model of ALKBH5 overexpression was constructed. Studies have shown that ALKBH5 could inhibit the proliferation and migration of zebrafish enteric neurons. CONCLUSIONS: ALKBH5 could demethylate TAGLN mRNA and up-regulate TAGLN expression, leading to the inhibition of proliferation and migration of enteric neural crest cells and contributing to the occurrence of HSCR.

ABSTRACT

Intestinal malrotation in newborns often requires urgent surgical treatment, especially in the presence of volvulus. Therefore, early­stage diagnosis is critical. In the present study, differentially expressed plasma microRNAs (miRNAs) were screened for in patients with intestinal malrotation using high­throughput Illumina sequencing, and validated using reverse transcription­quantitative PCR. Receiver operating characteristic curve (ROC) analysis was conducted to evaluate their specificity, sensitivity and assess their diagnostic value for intestinal malrotation. Bioinformatics analysis was performed to investigate the functions associated with the dysregulated miRNAs. A profile consisting of 28 differentially expressed plasma miRNAs was obtained, of which nine were verified to exhibit significantly altered expression. According to a ROC analysis, four of these could represent novel early­stage, non­invasive biomarkers for intestinal malrotation. Bioinformatics analysis demonstrated that the differentially expressed miRNAs were predominantly involved in 'metal ion transmembrane transporter activity' and 'calcium­dependent protein binding', which may be related to the 'endocytosis' pathway. In conclusion, significantly differentially expressed plasma miRNAs were identified in congenital intestinal malrotation and their potential roles were described. These differentially expressed miRNAs may serve as biomarkers of intestinal malrotation and improve early diagnosis for this condition.
