Upadacitinib for Induction of Remission in Pediatric Ulcerative Colitis: An International Multi‑center Study.

Background And Aims: Data on upadacitinib therapy in children with ulcerative colitis (UC) or unclassified inflammatory bowel disease (IBD-U) are scarce. We aimed to evaluate the effectiveness and safety of upadacitinib as an induction therapy in pediatric UC or IBD-U.

Methods: In this multicenter retrospective study, children treated with upadacitinib for induction of remission of active UC or IBD-U from 30 centers worldwide were enrolled.

Gut microbiota wellbeing index predicts overall health in a cohort of 1000 infants.

The human gut microbiota is central in regulating all facets of host physiology, and in early life it is thought to influence the host's immune system and metabolism, affecting long-term health. However, longitudinally monitored cohorts with parallel analysis of faecal samples and health data are scarce. In our observational study we describe the gut microbiota development in the first 2 years of life and create a gut microbiota wellbeing index based on the microbiota development and health data in a cohort of nearly 1000 infants using clustering and trajectory modelling.

Assessment of disease severity with magnetic resonance cholangiography in pediatric-onset primary sclerosing cholangitis.

Objectives: Magnetic resonance cholangiopancreaticography (MRCP) has supplanted endoscopic retrograde cholangiopancreaticography (ERCP) as the preferred imaging modality for primary sclerosing cholangitis (PSC). However, data about the accuracy of MRCP in assessing disease severity are limited, particularly in children. We assessed the accuracy of MRCP in disease severity evaluation and investigated the correlation between imaging findings and biochemical parameters (including the multivariate risk index SCOPE) in patients with pediatric-onset PSC.

Burden of oral diseases predicts development of excess weight in early adolescence: a 2-year longitudinal study.

Unlabelled: Dental caries, gingivitis, and excess weight are highly prevalent, interconnected chronic conditions. The association of oral health with the development of adiposity among children is sparsely addressed. We examined the association of oral health to the development of excess weight and central obesity in early adolescence during a 2-year follow-up period.

Paternal and induced gut microbiota seeding complement mother-to-infant transmission.

Microbial colonization of the neonatal gut involves maternal seeding, which is partially disrupted in cesarean-born infants and after intrapartum antibiotic prophylaxis. However, other physically close individuals could complement such seeding. To assess the role of both parents and of induced seeding, we analyzed two longitudinal metagenomic datasets (health and early life microbiota [HELMi]: N = 74 infants, 398 samples, and SECFLOR: N = 7 infants, 35 samples) with cesarean-born infants who received maternal fecal microbiota transplantation (FMT).

Human milk oligosaccharide composition is affected by season and parity and associates with infant gut microbiota in a birth mode dependent manner in a Finnish birth cohort.

Background: Human milk oligosaccharides (HMOs), their determinants, infant gut microbiota and health are under extensive research; however, seldom jointly addressed. Leveraging data from the HELMi birth cohort, we investigated them collectively, considering maternal and infant secretor status.

Methods: HMO composition in breastmilk collected 3 months postpartum (n = 350 mothers) was profiled using high-performance liquid chromatography.

Background And Objectives: Current data on ustekinumab therapy in children with ulcerative colitis (UC) or unclassified inflammatory bowel disease (IBDU) are limited. We aimed to evaluate the effectiveness and safety of ustekinumab in pediatric UC and IBDU.

Methods: This multicenter retrospective study included 16 centers affiliated with the IBD Interest and Porto groups of ESPGHAN.

Changes in health-related quality of life during transition to adult healthcare: an international prospective cohort study.

Objective: To study changes in health-related quality of life (HRQoL) in adolescents and young adults (AYAs) with chronic medical conditions across the transfer to adult healthcare and associations of HRQoL with transition readiness and experience of care.

Methods: Participants in this international (Finland, Australia) prospective cohort study were recruited in the year prior to transfer to adult health services and studied 12 months later. In addition to two HRQoL scales (Pediatric Quality of Life inventory (PedsQL), 16D), the Am I ON TRAC for Adult Care Questionnaire and Adolescent Friendly Hospital Survey measured transition readiness and experience of care and categorised by quartile.

Dominant stricture in paediatric-onset primary sclerosing cholangitis is associated with impaired prognosis in a long-term follow-up.

Background And Objectives: The impact of dominant stricture (DS) on the outcomes of paediatric-onset primary sclerosing cholangitis (PSC) is unknown. This study was aimed at investigating the impact of DS on the clinical course and prognosis of patients with paediatric-onset PSC.

Methods: Patients with paediatric-onset PSC diagnosed between January 1993 and May 2017 were identified from hospital records or our PSC registry.

STEP-CD study: ustekinumab use in paediatric Crohn's disease-a multicentre retrospective study from paediatric IBD Porto group of ESPGHAN.

Ustekinumab is an effective therapy for adult Crohn's disease (CD), but data in paediatric CD patients are scarce. The aim of the study was to describe the real-life effectiveness and safety of ustekinumab in paediatric CD. This is a multicentre review of children with Crohn's disease treated with ustekinumab.

The need for surgery in pediatric patients with inflammatory bowel disease treated with biologicals.

Purpose: Inflammatory bowel disease (IBD) in childhood often presents with a more extensive and more aggressive disease course than adult-onset disease. We aimed to evaluate if biological treatment started in childhood decreases the need for intestinal surgery over time.

Methods: This was a retrospective, single-center, cohort study.

Psychological well-being of children and adolescents with inflammatory bowel disease.

Objectives: Prior studies on the psychological well-being in pediatric inflammatory bowel disease (PIBD) have reported controversial results. Our aim was to compare the psychological well-being and lifestyle factors in patients with PIBD and their controls and to assess the role of contributing disease characteristics.

Methods: This cross-sectional study included 60 PIBD patients aged 6-17 years (26 with Crohn's disease [CD], 34 with ulcerative colitis [UC] or unclassified colitis [IBD-U]) from two university hospitals in Finland, and their age- and sex-matched healthy controls.

Health-related quality of life and self-reported health status in adolescents with chronic health conditions before transfer of care to adult health care: an international cohort study.

Background: Heath-related quality of life (HRQoL) is lower in adolescents with chronic health conditions compared to healthy peers. While there is evidence of some differences according to the underlying condition and gender, differences by measure and country are poorly understood. In this study we focus on the differences in HRQoL in adolescents with various chronic medical conditions in the year before transfer of care to adult health services.

Updates on the management of inflammatory bowel disease from periconception to pregnancy and lactation.

Inflammatory bowel disease (IBD) affects reproductive planning due to psychological effects and mechanical problems related to surgery. Children of people with IBD have an increased risk of about 10% if one parent has IBD and up to 33% if both parents have IBD. The fertility of people with IBD is similar to the general population, but fertility might be reduced in individuals with active IBD, ileal pouch-anal anastomosis, or perianal Crohn's disease.

Drug levels of VEDOLIZUMAB in patients with pediatric-onset inflammatory bowel disease in a real-life setting.

Vedolizumab (VDZ) is used off-label in pediatric inflammatory bowel disease (PIBD). There are less data on drug levels to achieve and maintain remission in children. We aimed to study vedolizumab (VDZ) trough levels in a pediatric population in a real-life setting.

Machine-learning analysis of cross-study samples according to the gut microbiome in 12 infant cohorts.

There are challenges in merging microbiome data from diverse research groups due to the intricate and multifaceted nature of such data. To address this, we utilized a combination of machine-learning (ML) models to analyze 16S sequencing data from a substantial set of gut microbiome samples, sourced from 12 distinct infant cohorts that were gathered prospectively. Our initial focus was on the mode of delivery due to its prior association with changes in infant gut microbiomes.
