The relation between dietary polysaccharide intake and urinary excretion of tetraglucoside.

The urinary metabolite tetraglucoside (Glc4) is a potential biomarker for hepatic glycogen storage diseases (GSDs). Glc4 is believed to reflect body glycogen content and/or turnover. However, dietary polysaccharide intake may influence Glc4 excretion, potentially limiting the utility of Glc4 as a monitoring biomarker in hepatic GSDs.

The Pulmonary Artery Pulsatility Index Provides No Additional Prognostic Information in Pediatric Pulmonary Arterial Hypertension.

Background/objectives: The pulmonary artery pulsatility index (PAPi, calculated as (SPAP - DPAP)/mRAP) has been suggested as a measure of right ventricular-vascular coupling (RVVC) and as a prognostic parameter in cardiovascular conditions, particularly right ventricular failure. This retrospective study investigated the relationship between the PAPi and its components with disease severity parameters, the RVVC, and clinical outcomes in children with pulmonary arterial hypertension (PAH).

Methods: We analyzed data from 111 children from the Dutch National Registry with PAH.

Impact of Persistent Pulmonary Hypertension of the Newborn in Neonates with Dextro-transposition of the Great Arteries.

Objectives: This study aimed to assess the impact of persistent pulmonary hypertension of the newborn (PPHN) on perioperative morbidity and mortality in patients with dextro-transposition of the great arteries. Secondarily, we evaluated the association between postoperative outcomes and intraoperative variables including the duration of cardiopulmonary bypass, cerebral oxygen desaturation, and hypotension.

Design: Retrospective observational study.

Risk and Protective Factors of Psychosocial Functioning in Survivors of Childhood Cancer: Results of the DCCSS-LATER Study.

Objective: This study examines the association between psychosocial risk and protective factors and a wide range of psychosocial outcomes including emotional, social, cognitive, and physical domains in childhood cancer survivors (CCS).

Methods: CCS from the Dutch Childhood Cancer Survivor Study (DCCSS)-LATER cohort (diagnosed 1963-2001) part 2 (age ≥ 18 years, diagnosed < 18 years, ≥ 5 years since diagnosis) completed questionnaires on psychosocial risk and protective factors (Benefit and Burden Scale, Illness Cognition Questionnaire, Rosenberg Self-Esteem Scale, and Impact of Cancer Scale), and psychosocial outcomes (Hospital Anxiety and Depression Scale, Self-Rating Scale for Post-Traumatic Stress Disorder, TNO-AZL Questionnaire for Adult Health-Related Quality of Life, and Short Form-36). Associations were assessed with regression analysis, adjusting for attained age, sex, number of health conditions, and time since diagnosis, while correcting for multiple testing (p < 0.

Global Lung Function Initiative reference values for multiple breath washout indices.

Background: Multiple breath washout is a lung function test based on tidal breathing that assesses lung volume and ventilation distribution. The aim of this analysis was to use the Global Lung Function Initiative methodology to develop all-age reference equations for the multiple breath washout indices lung clearance index (LCI) and functional residual capacity (FRC).

Methods: Multiple breath washout data from healthy individuals were collated from sites.

Parents' and healthcare professionals' experiences with the content of an individual care plan for pediatric palliative care: a mixed-method study.

Background: The Individual Care Plan (ICP) for pediatric palliative care translates the general guideline recommendations into a personalized plan for the child. Various documents exist in pediatrics globally, aimed at facilitating anticipatory care or coordinating end-of-life care. The ICP aims both, but user experiences have not been studied post-development.

A specific serum lipid signature characterizes patients with glycogen storage disease type Ia.

Glycogen storage disease type Ia (GSDIa) is a rare, inherited glucose-6-phosphatase-α (G6Pase-α) deficiency-induced carbohydrate metabolism disorder. Although hyperlipidemia is a hallmark of GSDI, the extent of lipid metabolism disruption remains incompletely understood. Lipidomic analysis was performed to characterize the serum lipidome in patients with GSDIa, by including age- and sex-matched healthy controls and age-matched hypercholesterolemic controls.

Epithelial Interleukin-1 Receptor-Like-1 Activation Is Contingent on Interleukin-33 Isoforms and Asthma-Related Receptor Variation.

Introduction: The interleukin-33/interleukin-1 receptor-like-1 (IL-33/IL1RL1) signalling pathway is implicated in asthma pathogenesis, with IL1RL1 nonsynonymous genetic polymorphisms associated with disease risk. We aimed to determine these variants' effect on IL1RL1 signalling induced by different IL33 isoforms thought to be elevated in the asthmatic airway.

Method: In a project funded by GSK plc, which has developed an IL-33 receptor inhibitor for asthma treatment, human embryonic kidney 293 (HEK293) cells expressing secreted embryonic alkaline phosphatase (SEAP) driven by a nuclear factor kappa-beta (NF-κB) promoter, were transiently transfected with IL1RL1, containing one of four extracellular and Toll/interleukin 1 receptor (TIR) domain haplotypes.

The academic impact of paediatric research agendas: a descriptive analysis.

Background: Increasingly, researchers are involving children and young people in designing paediatric research agendas, but as far as we were able to determine, only one report exists on the academic impact of such an agenda. In our opinion, the importance of insight into the impact of research agendas designed together with children and young people cannot be overstated. The first aim of our study was therefore to develop a method to describe the academic impact of paediatric research agendas.

Continuous glucose monitoring metrics in people with liver glycogen storage disease and idiopathic ketotic hypoglycemia: A single-center, retrospective, observational study.

Background: Cohort data on continuous glucose monitoring (CGM) metrics are scarce for liver glycogen storage diseases (GSDs) and idiopathic ketotic hypoglycemia (IKH). The aim of this study was to retrospectively describe CGM metrics for people with liver GSDs and IKH.

Patients And Methods: CGM metrics (descriptive, glycemic variation and glycemic control parameters) were calculated for 47 liver GSD and 14 IKH patients, categorized in cohorts by disease subtype, age and treatment status, and compared to published age-matched CGM metrics from healthy individuals.

Long-term safety of sapropterin in paediatric and adult individuals with phenylalanine hydroxylase deficiency: Final results of the Kuvan® Adult Maternal Paediatric European Registry multinational observational study.

Phenylketonuria is a rare inherited disorder that disrupts the metabolism of phenylalanine (Phe) to tyrosine by phenylalanine hydroxylase (PAH). Sapropterin dihydrochloride (Kuvan®) is approved for use in Europe to reduce blood Phe levels and improve Phe tolerance in sapropterin-responsive individuals. KAMPER (NCT01016392) is an observational, multinational registry assessing long-term safety and efficacy of sapropterin.

Socioeconomic Inequalities in the External Exposome in European Cohorts: The EXPANSE Project.

Socioeconomic inequalities in the exposome have been found to be complex and highly context-specific, but studies have not been conducted in large population-wide cohorts from multiple countries. This study aims to examine the external exposome, encompassing individual and environmental factors influencing health over the life course, and to perform dimension reduction to derive interpretable characterization of the external exposome for multicountry epidemiological studies. Analyzing data from over 25 million individuals across seven European countries including 12 administrative and traditional cohorts, we utilized domain-specific principal component analysis (PCA) to define the external exposome, focusing on air pollution, the built environment, and air temperature.

Embracing the challenges of neonatal and paediatric pulmonary hypertension.

Paediatric pulmonary arterial hypertension (PAH) shares common features with adult disease, but is associated with several additional disorders and challenges that require unique approaches. This article discusses recent advances, ongoing challenges and distinct approaches for caring for infants and children with PAH, as presented by the paediatric task force of the 7th World Symposium on Pulmonary Hypertension. We provide updates on diagnosing, classifying, risk-stratifying and treating paediatric pulmonary hypertension (PH) and identify critical knowledge gaps.

The Practical Application of the Individual Care Plan for Pediatric Palliative Care: A Mixed-Method Study.

Background/objective: The Individual Care Plan (ICP) for pediatric palliative care was developed to provide person-centered care for the individual child and family. Currently, a lack of clarity remains regarding the use and function of the ICP in daily practice. To further implement the ICP, it is important to identify how parents and healthcare professionals use the ICP and which obstacles or benefits are experienced.
