A clinical consensus paper on jejunal tube feeding in children.

BACKGROUND: Feeding problems are common in children with complex medical problems or acute critical illness and enteral nutrition may be required. In certain situations, gastric tube feeding is poorly tolerated or may not be feasible. When feed intolerance persists despite appropriate adjustments to oral and gastric enteral regimens, jejunal tube feeding can be considered as an option for nutrition support. METHODS: A multidisciplinary expert working group of the Australasian Society of Parenteral and Enteral Nutrition was convened. They identified topic questions and five key areas of jejunal tube feeding in children. Literatures searches were undertaken on Pubmed, Embase, and Medline for all relevant studies, between January 2000 and September 2022 (n = 103). Studies were assessed using National Health and Medical Research Council guidelines to generate statements, which were discussed as a group, followed by voting on statements using a modified Delphi process to determine consensus. RESULTS: A total of 24 consensus statements were created for five key areas: patient selection, type and selection of feeding tube, complications, clinical use of jejunal tubes, follow-up, and reassessment. CONCLUSION: Jejunal tube feeding is a safe and effective means of providing nutrition in a select group of pediatric patients with complex medical needs, who are unable to be fed by gastric tube feeding. Appropriate patient selection is important as complications associated with jejunal tube feeding are not uncommon, and although mostly minor, can be significant or require tube reinsertion. All children receiving jejunal tube feeding should have multidisciplinary team assessment and follow-up.

Maternal asthma is associated with reduced lung function in male infants in a combined analysis of the BLT and BILD cohorts.

RATIONALE: Asthma in pregnancy is associated with respiratory diseases in the offspring. OBJECTIVE: To investigate if maternal asthma is associated with lung function in early life. METHODS: Data on lung function measured at 5-6 weeks of age were combined from two large birth cohorts: the Bern Infant Lung Development (BILD) and the Australian Breathing for Life Trial (BLT) birth cohorts conducted at three study sites (Bern, Switzerland; Newcastle and Sydney, Australia). The main outcome variable was time to reach peak tidal expiratory flow as a percentage of total expiratory time(tPTEF:tE%). Bayesian linear hierarchical regression analyses controlling for study site as random effect were performed to estimate the effect of maternal asthma on the main outcome, adjusting for sex, birth order, breast feeding, weight gain and gestational age. In separate adjusted Bayesian models an interaction between maternal asthma and sex was investigated by including an interaction term. MEASUREMENTS AND MAIN RESULTS: All 406 BLT infants were born to mothers with asthma in pregnancy, while 193 of the 213 (91%) BILD infants were born to mothers without asthma. A significant interaction between maternal asthma and male sex was negatively associated with tPTEF:tE% (intercept 37.5; estimate: -3.5; 95% credible interval -6.8 to -0.1). Comparing the model posterior probabilities provided decisive evidence in favour of an interaction between maternal asthma and male sex (Bayes factor 33.5). CONCLUSIONS: Maternal asthma is associated with lower lung function in male babies, which may have lifelong implications on their lung function trajectories and future risk of wheezing and asthma.
