The incidence of acute pancreatitis in children has increased significantly over the past decade. The increase was greatest in children with idiopathic pancreatitis. It remains unclear whether this reflects a true incidence increase or improved clinical awareness.

Human breast milk contains numerous biomolecules. Human milk oligosaccharides (HMOs) are the third most abundant component of breast milk, after lactose and lipids. Amongst the synthetized HMOs, 2′-fucosyllactose (2′-FL) and lacto-N-neotetraose (LNnT) are widely studied and are considered safe for infant nutrition. Several studies have reported the health benefits of HMOs, which include modulation of the intestinal microbiota, anti-adhesive effect against pathogens, modulation of the intestinal epithelial cell response, and development of the immune system. The amount and diversity of HMOs are determined by the genetic background of the mothers (HMO secretors or non-secretors). The non-secretor mothers secrete lower HMOs than secretor mothers. The breastfed infants of secretor mothers gain more health benefit than those of non-secretor mothers. In conclusion, supplementation of infant formula with 2′-FL and LNnT is a promising innovation for infant nutrition.

Background and Objectives: Microbial communities residing in the gut play a major role in the communication between the gut and the brain through neural, immune, and hormonal routes. Changes in abundance of beneficial intestinal bacteria can affect health of individuals. Conversely, drugs, disease, diet and other factors can alter the gut microbiome. However, there is limited information on the effect of exogenous factors on gut microbiota. In this study, we investigated wheth- er a beneficial bacterium, the probiotic Lactobacillus plantarum IS-10506, can stimulate the gut–brain axis using Wistar rats. Materials and Methods: The animals were divided into two groups: one received L. plantarum IS strain 10506 supple- mentation, while the control group received no treatment. Activation of the gut–brain axis was evaluated by immunohisto- chemical analysis of intestinal and brain serotonin (5-HT) and brain neurotrophin (NT), serotonin transporter (5-HTT), and brain-derived neurotrophic factor (BDNF) levels. Results: The results showed that BDNF (p< 0.000), NT (p< 0.000007), and 5-HTT (p< 0.000007) expression was upregu- lated in the brain along with intestinal 5-HT (p< 0.000) level in rats treated with L. plantarum strain IS-10506 relative to the control group. Conclusion: The probiotic L. plantarum IS-10506 stimulates the gut–brain axis and can potentially promote brain develop- ment and function.

Group A rotavirus (RVA) is the most important cause of severe gastroenteritis among children worldwide, and effective RVA vaccines have been introduced in many countries. Here we performed a molecular epidemiological analysis of RVA infection among pediatric patients in East Java, Indonesia, during 2015-2018. A total of 432 stool samples were collected from hospitalized pediatric patients with acute gastroenteritis. None of the patients in this cohort had been immunized with an RVA vaccine. The overall prevalence of RVA infection was 31.7% (137/432), and RVA infection was significantly more prevalent in the 6-to 11-month age group than in the other age groups (P < 0.05). Multiplex reverse transcription-PCR (RT-PCR) revealed that the most common G-P combination was equine-like G3P[8] (70.8%), followed by equine-like G3P[6] (12.4%), human G1P[8] (8.8%), G3P[6] (1.5%), and G1P[6] (0.7%). Interestingly, the equine-like strains were exclusively detected until May 2017, but in July 2017 they were completely replaced by a typical human genotype (G1 and G3), suggesting that the dynamic changes in RVA genotypes from equine-like G3 to typical human G1/G3 in Indonesia can occur even in the country with low RVA vaccine coverage rate. The mechanism of the dynamic changes in RVA genotypes needs to be explored. Infants and children with RVA-associated gastroenteritis presented more frequently with some dehydration, vomiting, and watery diarrhea, indicating a greater severity of RVA infection compared to those with non-RVA gastroenteritis. In conclusion, a dynamic change was found

BackgroundRotavirus infections are a major cause of diarrhea in children in both developed and developing countries. Rotavirus genetics, patient immunity, and environmental factors are thought to be related to the severity of acute diarrhea due to rotavirus in infants and young children. The objective of this study was to provide a correlation between rotavirus genotypes, clinical factors and degree of severity of acute diarrhea in children under 5 years old in Surabaya, Indonesia.MethodsA cross-sectional study was conducted in children aged 1–60 months with acute diarrhea hospitalized in Soetomo Hospital, Surabaya, Indonesia from April to December 2013. Rotavirus in stool specimens was identified by ELISA and genotyping (G-type and P-type) using multiplex reverse transcription PCR. Severity was measured using the Ruuska and Vesikari scoring system. The clinical factors were investigated included patient’s age (months), hydration, antibiotic administration, nutritional state, co-bacterial infection and co-viral infection.ResultsA total of 88 children met the criteria; 80.7% were aged 6–24 months, watery diarrhea was the most common type (77.3%) and 73.6% of the subjects were co-infected with bacteria, of which pathogenic Escherichia coli was the most common (42.5%). The predominant VP7 genotyping (G-type) was G2 (31.8%) and that of VP4 genotyping (P-type) was P[4] (31.8%). The predominant rotavirus genotype was G2P[4] (19.3%); G1P[4] and G9P[4] were uncommon with a prevalence of 4.5%. There were significant differences between the common genotype and uncommon genotype with respect to the total severity score of diarrhea (p <0.05). G3, G4 and G9 were significantly correlated with severe diarrhea (p = 0.009) in multivariate analyses and with frequency of diarrhea (>10 times a day) (p = 0.045) in univariate analyses, but there was no significant correlation between P typing and severity of diarrhea. For combination genotyping of G and P, G2P[4] was significantly correlated with severe diarrhea in multivariate analyses (p = 0.029).ConclusionsThere is a correlation between rotavirus genotype and severity of acute diarrhea in children. Genotype G2P[4] has the highest prevalence. G3, G4, G9 and G2P[4] combination genotype were found to be associated with severe diarrhea.
