RESUMEN
OBJECTIVES: This study aims to compare the intestinal microbiota and intestinal inflammation of children with esophageal atresia (EA) to matched healthy controls, and to investigate the relationship between these factors and clinical outcomes. METHODS: A cross-sectional study of 35 children with EA and 35 matched healthy controls (HC) from a single tertiary pediatric hospital in Australia was conducted. Demographic and dietary data were collected using surveys. Stool samples were analyzed using 16S rRNA sequencing, and fecal calprotectin measurements were used to measure intestinal inflammation. Comparisons were made between the groups, and correlations between the microbiota and clinical factors were investigated in the EA cohort. RESULTS: Compared to HC, children with EA had similar alpha diversity, but beta diversity analysis revealed clustering of EA and HC cohorts. Children with EA had a significantly higher relative abundance of the order Lactobacillales, and a lower abundance of the genus uncultured Bacteroidales S24-7. Fecal calprotectin was significantly higher in children with EA compared to HC. In the EA cohort, children taking proton pump inhibitors (PPI's) had lower alpha diversity and higher calprotectin levels compared to those not taking PPI's. There was a negative correlation between calprotectin and length/height-for-age z scores, and children with higher calprotectin levels had a greater burden of gastrointestinal symptoms. CONCLUSIONS: Children with EA have an altered intestinal microbiota compared to HC, which is likely related to PPI use, and may be impacting on growth and quality of life. It is important to rationalize PPI use in this cohort.

Cystic fibrosis (CF) is a common disorder of autosomal recessive inheritance, that once conferred a life expectancy of only a few months. Over recent years, significant advances have been made to CF therapeutic approaches, changing the face of the disease, and facilitating the partial restoration of pancreatic function. This mini review summarizes the current landscape of exocrine pancreatic management in CF and explores areas for future direction and development.
RESUMEN
OBJECTIVES: Children with esophageal atresia (EA) often have feeding difficulties and dysphagia, which may compromise their nutritional status. This study aimed to compare dietary intake between children with EA and matched healthy controls (HC) and to investigate the relationship between dietary factors, growth, dysphagia, and feeding difficulties in the EA cohort. METHODS: This cross-sectional cohort study recruited children with EA and HC aged 2-17 years from a tertiary pediatric hospital in Australia. Growth parameters were measured. Dietary intake was assessed using the validated Australian Child and Adolescent Eating Survey. Dysphagia and feeding difficulties were assessed using objective questionnaires. RESULTS: Twenty-one children with EA were matched for age and sex with 21 HC. Compared to HC, children with EA had lower mean z scores for height-for-age, but mean weight-for-age and body mass index-for-age z scores were similar. Energy intake was similar between the groups. The diet of children with EA consisted of a higher proportion of fats and lower proportion of carbohydrates compared to matched HC. Dysphagia severity in children with EA positively correlated with proportion of energy from fats and saturated fats. CONCLUSIONS: Children with EA have similar energy intake and growth parameters to HC, but their diet consists of a higher proportion of fats and lower proportion of carbohydrates compared to HC. Targeted dietary interventions and parental education are necessary.

INTRODUCTION: Chronic gastrointestinal and respiratory conditions of childhood can have long-lasting physical, psychosocial and economic effects on children and their families. Alterations in diet and intestinal and respiratory microbiomes may have important implications for physical and psychosocial health. Diet influences the intestinal microbiome and should be considered when exploring disease-specific alterations. The concepts of gut-brain and gut-lung axes provide novel perspectives for examining chronic childhood disease(s). We established the 'Evaluating the Alimentary and Respiratory Tracts in Health and disease' (EARTH) research programme to provide a structured, holistic evaluation of children with chronic gastrointestinal and/or respiratory conditions. METHODS AND ANALYSIS: The EARTH programme provides a framework for a series of prospective, longitudinal, controlled, observational studies (comprised of individual substudies), conducted at an Australian tertiary paediatric hospital (the methodology is applicable to other settings). Children with a chronic gastrointestinal and/or respiratory condition will be compared with age and gender matched healthy controls (HC) across a 12-month period. The following will be collected at baseline, 6 and 12 months: (i) stool, (ii) oropharyngeal swab/sputum, (iii) semi-quantitative food frequency questionnaire, (iv) details of disease symptomatology, (v) health-related quality of life and (vi) psychosocial factors. Data on the intestinal and respiratory microbiomes and diet will be compared between children with a condition and HC. Correlations between dietary intake (energy, macro-nutrients and micro-nutrients), intestinal and respiratory microbiomes within each group will be explored. Data on disease symptomatology, quality of life and psychosocial factors will be compared between condition and HC cohorts.Results will be hypothesis-generating and direct future focussed studies. There is future potential for direct translation into clinical care, as diet is a highly modifiable factor. ETHICS AND DISSEMINATION: Ethics approval: Sydney Children's Hospitals Network Human Research Ethics Committee (HREC/18/SCHN/26). Results will be presented at international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04071314.
