Lipid droplets in human milk have a mode diameter of ∼4 μm and are surrounded by native phospholipid-rich membrane. Current infant formulas (IMFs) contain small lipid (mode ∼0.5 μm) primarily coated proteins. A concept IMF was developed mimicking more closely the structure composition droplets. This randomized, controlled, double-blind equivalence trial evaluates safety tolerance with large, phospholipid–coated 3–5 containing vegetable dairy lipids healthy, term infants. Fully formula-fed...

Irritable bowel syndrome (IBS) and functional abdominal pain (syndrome) (FAP(S)) are common pediatric disorders, characterized by chronic or recurrent pain. Treatment is challenging, especially in children with persisting symptoms. Gut-directed hypnotherapy (HT) performed a therapist has been shown to be effective these children, but still unavailable many due costs, lack of qualified child-hypnotherapists because it requires significant investment time child parent(s).

Methotrexate [MTX] is an immunomodulating drug that can be used to maintain remission in patients with Crohn's disease [CD], but data on efficacy and tolerability children teenagers are scarce. We evaluated the long-term of MTX monotherapy after thiopurine therapy paediatric CD patients. A multicenter cohort users who stopped thiopurines due ineffectiveness or intolerance between 2002 2012 were included followed for at least 12 months.

Human milk comprises large fat globules enveloped by a native phospholipid membrane, whereas infant formulas contain small, protein-coated lipid droplets. Previous experimental studies indicated that mimicking the architecture of human droplets in formula (IMF) alters metabolism with lasting beneficial impact on later metabolic health. To evaluate follow-up (FU) study randomized, controlled trial whether Concept IMF large, phospholipid-coated enriched dairy lipids beneficially impacts...

Primary sclerosing cholangitis (PSC) is a rare bile duct disease strongly associated with inflammatory bowel (IBD). Whole-exome sequencing (WES) has contributed to understanding the molecular basis of very early-onset IBD, but protein-altering genetic variants have not been identified for PSC. We performed WES in patients diagnosed PSC ≤ 12 years investigate contribution PSC.In this multicentre study, was on 87 DNA samples from 29 patient-parent trios selected (minor allele frequency < 2%)...
