Patient perspective on exercise practices, preferences, and barriers in pediatric nonalcoholic fatty liver disease: A multicenter survey.

Nonalcoholic fatty liver disease (NAFLD) is prevalent among children, and lifestyle modification is the primary treatment approach. However, the optimal exercise duration, frequency, and intensity for managing NAFLD remain undefined. This study aimed to gain insights from the patient perspective by examining exercise behaviors, preferences, and barriers in children with NAFLD. A multicenter survey was conducted among children 8-18 years with NAFLD in pediatric gastroenterology clinics. Participants completed a questionnaire on exercise practices, preferences, and barriers, while parents completed a questionnaire on their willingness and ability to support their child's exercise. Data were analyzed using χ 2 test with Yates' correction and two-sample t test. The study included 408 children with NAFLD, with a mean age of 13.8 years. Approximately 52.5% of participants had physical education classes at school, while 59.5% engaged in extracurricular exercise, averaging 3.7 days per week. However, 11.5% reported no physical activity. A significant majority (81.1%) expressed interest in increasing their exercise levels, primarily driven by health-related factors. Time-related constraints were the most cited barriers to exercise (53.7%). Approximately 80% of parents demonstrated willingness and ability to support their child's exercise regimen. This study provides insights into exercise behaviors, preferences, and barriers among children with NAFLD. Half of the children lacked exercise opportunities at school but expressed interest in increasing their physical activity. Time limitation was the major obstacle cited. Parents are motivated to support increased physical activity. Exercise intervention programs for NAFLD should consider the perspective of the children and their families.

Simulation-based training of endoscopic hemostasis for Japanese pediatric endoscopy learners: a pilot program

Background and AimsEndoscopic hemostasis training, often in emergencies, can be challenging for pediatric endoscopists. This study aimed to establish hands-on seminar sessions using the novel clip hemostasis simulator, and to explore the underlying concerns about endoscopic hemostasis among pediatric endoscopists and the potential of simulator-based training (SBT). MethodsA SBT course was incorporated into seminars by the Japanese Society for Pediatric Gastroenterology, Hepatology, and Nutrition. Surveys with Visual Analog Scale (VAS, 0-100) completed by consenting pediatricians during four seminars from October 2021 to March 2023, were compared with the responses of adult gastrointestinal (GI) residents and junior residents. ResultsFifty-two pediatric endoscopists (median age 31, PGY 7) were enrolled. A median VAS score of 47 (IQR 23.5-65) for understanding endoscopic hemostasis, significantly lower than adult GI residents (median 76, IQR 58-82, P<0.001) and comparable to junior residents (median 54, IQR 50-65). Pediatric endoscopists' confidence in independently performing hemostasis was low, with a median score of 0 (IQR 0-16.5), below adult GI residents (median 67, IQR 49-77, P<0.001) and junior residents (median 11.5, IQR 10-39, P=0.014). Regarding skill enhancement by SBT, a median score of 94.5 showed high and no significant difference from junior residents and adult GI residents. All pediatric endoscopists expressed interest in repeated SBT sessions. Discussion and Future ProspectsPediatric endoscopists were concerned about their competence in endoscopic hemostasis. The simplified SBT programs with the simulator, may potentially improve their skills and confidence.

Current practices and challenges of registered dietitians in the nutritional management of children with cerebral palsy in South Africa

Background: Feeding difficulties and subsequent malnutrition are common in children with cerebral palsy (CP). Objectives: A study was undertaken to determine the current practices and challenges of South African registered dietitians (SA RD) regarding the nutritional management of children with CP, to compare these practices with international guidelines and to compare the practices of private- and public-sector dietitians. Design: This was a cross-sectional descriptive study with an analytical component. Subjects and outcome measures: The SA RDs completed an online questionnaire, which was developed according to the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) guidelines. Participant answers were scored to assess their management of children with CP. Results: Of the 87 SA RDs who participated, 78 had work experience in CP (40 public and 38 private sector). Over two-thirds (n = 62/87, 71.2%) received training on the management of CP at university, albeit inadequate (n = 42/62, 67.7%). Common challenges that affect RDs’ management are poor caregiver compliance (n = 72; 92.2%) and poor networking between healthcare professionals (HCPs) (n = 60; 77.0%). The SA RD (n = 78) management of children with CP was significantly different from the ESPGHAN guidelines (p < 0.001). When comparing the total practice score, no significant difference was found between private- and public-sector RDs. The SA RDs did not achieve many of the recommended practices, particularly those pertaining to anthropometry. Conclusions: Improved training of SA RDs in the assessment and management of children with CP, and addressing barriers such as poor caregiver compliance, would enhance SA RDs’ competence to improve the nutritional management of children with CP.

Reevaluating the FDA's warning against the use of probiotics in preterm neonates: A societal statement by ESPGHAN and EFCNI.

The recent advisory issued by the United States Food and Drug Administration, cautioning against the routine administration of probiotics in preterm neonates, has sparked a lively debate within the scientific community. This commentary presents a perspective from members of the Special Interest Group on Gut Microbiota and Modifications within the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and other authors who contributed to the ESPGHAN position paper on probiotics for preterm infants, as well as representatives from the European Foundation for the Care of Newborn Infants. We advocate for a more nuanced and supportive approach to the use of certain probiotics in this vulnerable population, balancing the demonstrated benefits and risks.

Paediatric steatotic liver disease has unique characteristics:A multisociety statement endorsing the new nomenclature.

Nonalcoholic fatty liver disease (NAFLD) has been a commonly used term and diagnosis in paediatric hepatology, gastroenterology, and endocrinology clinics for over 30 years. A multisociety Delphi process has determined a new name "Steatotic Liver Disease"(SLD) as the overarching term for disorders associated with hepatic lipid accumulation. Our Societies give our support to steatotic liver disease as the best overarching term for use in our communities. Metabolic dysfunction-associated steatotic liver disease (MASLD) overcomes many of the shortcomings of the name NAFLD. Here, we highlight several points of the new nomenclature that are of particular importance for our community and their consequences for implementation including: diagnostic criteria, considering alternate diagnoses, practical implementation, research, advocacy, and education for paediatricians. As with all nomenclature changes, it will take a concerted effort from our paediatric societies to help integrate the optimal use of this into practice.

Evaluation of cardiac function in paediatric Wilson's disease patients with advanced echocardiographic modalities (strain and strain rate echocardiography).

In Wilson's disease (WD), copper accumulation in the organs and/or damage caused by oxygen free radicals occurs due to disturbances in copper excretion. In our study, we aimed to evaluate cardiac involvement with advanced echocardiographic modalities (tissue Doppler echocardiography, strain and strain-rate echocardiography). Twenty WD patients and 20 healthy children from the Pediatric Gastroenterology Department of Diyarbakır Children's Hospital were included in the study between 2022 and 2023. The mean age of the WD patients was 12.89 ± 3.79 years. Left ventricular wall thicknesses and diameters (diastolic interventricular septum thickness, diastolic left ventricular posterior wall thickness, left ventricular end-diastolic diameter), left ventricular diastolic function parameters (E, A, E/A, deceleration time) and left ventricular ejection fraction and tricuspid annular plane systolic excursion were similar and not statistically significantly different in the WD and control groups. Mitral lateral e', mitral septal e' and tricuspid lateral e' velocities were lower in the WD patients and statistically significantly different from the controls (p = 0.02, 0.04 and 0.005, respectively), as assessed by tissue Doppler echocardiography. Global longitudinal systolic strain was similar in the WD and control groups and no statistically significant difference was detected. Longitudinal early diastolic strain rate was lower in the WD patients and statistically significantly different (p = 0.002). Subclinical early diastolic dysfunction and segmental systolic dysfunction were detected in WD patients with advanced echocardiographic modalities, in addition to normal cardiac function as assessed by conventional echocardiography. Advanced echocardiographic modalities can be used in the follow up of WD patients.

Innovative Diagnostic Tool: Convolutional Neural Network for Early Fat Malabsorption Detection in Pediatric Patients with Chronic Diarrhea

Background: Chronic diarrhea in children poses a significant clinical challenge and can lead to adverse health outcomes. Among various causes, fat malabsorption is particularly concerning, as it may lead to inadequate nutrient absorption, malnutrition, and impaired growth. Prompt and precise diagnosis is crucial for implementing effective treatments. Objectives: The goal of this study is to utilize deep learning to create a superior diagnostic tool that exceeds traditional methods, facilitating the early identification of fat malabsorption in children suffering from chronic diarrhea. Methods: In a preliminary study involving 100 pediatric patients, 25 machine learning algorithms were evaluated. The convolutional neural network (CNN) was identified as the most effective and subsequently refined through hyperparameter tuning. Results: The CNN model exhibited exceptional performance, attaining a test accuracy of 97% and an area under the curve (AUC) score of 99.4%. These results underscore its reliability in accurately identifying cases of fat malabsorption. Conclusions: This research represents noteworthy progress in pediatric gastroenterology, merging deep learning techniques with medical expertise to develop a dependable and rapid diagnostic tool. This innovative method promises significant improvements in detecting fat malabsorption, potentially transforming clinical practices and enhancing patient outcomes in children with chronic diarrhea.

Assessing impaired gastric accommodation in children with functional constipation using the water load test.

This study aimed to evaluate gastric accommodation in pediatric patients with functional constipation using the water load test. This was a cross-sectional case-control study. Herein, the water load test results of children aged >4 years with functional constipation referred to a Pediatric Gastroenterology Outpatient Clinic (functional constipation group) were compared with those of a control group (without functional constipation or chronic abdominal pain) recruited from two public schools. Clinical manifestations outlined in the Rome IV criteria were used to diagnose functional constipation. Water load tests were performed after 3 h of fasting. For the test, the participants were asked to drink as much water as possible in 3 min. A total of 36 patients and 77 students were included in the functional constipation and control groups, respectively. There was no significant difference in age between the groups (8.6 ± 2.3 years and 8.8 ± 1.8 years in the functional constipation and control groups, respectively). The water load test showed intake volumes of 390 ± 245 mL and 528 ± 219 mL in the functional constipation and control groups, respectively (p = 0.001). The maximum volume in the water load test correlated with the 24 h daily intake of energy (rS = +0.42, p = 0.012), protein (rS = +0.48, p = 0.004), and water (rS = +0.39, p = 0.020) only in the group with functional constipation. According to the water load test, gastric accommodation was impaired in children with severe functional constipation. The impairment of gastric accommodation in children with severe functional constipation is related to food intake.

Pediatric retrograde cricopharyngeal dysfunction diagnosed by high-resolutionimpedance manometry.

The inability to burp, known as retrograde cricopharyngeal dysfunction (R-CPD), was initially described in adults. The proposed clinical diagnostic criteria for R-CPD include belching inability, abdominal bloating and discomfort/nausea, postprandial chest pain, and involuntary noises. Botulinum toxin injection to the cricopharyngeal muscle has been reported to be beneficial. High-resolution esophageal impedance-manometry (HRIM) features in adolescent patients with R-CPD have not been described yet. The aim of our study was to describe the clinical and HRIM findings of pediatric patients with R-CPD. Clinical and manometric features of five pediatric patients diagnosed with R-CPD were reviewed. HRIM study protocol was modified to include the consumption of carbonated drink to provoke symptoms and distinctive manometric features. We report five female patients aged 15-20 years who presented with an inability to burp and involuntary throat sounds. HRIM revealed normal upper esophageal sphincter (UES) relaxation during swallowing, but abnormal UES relaxation with concurrent high esophageal impedance reflecting air entrapment and secondary peristalsis following the carbonated drink challenge. Four patients exhibited esophageal motility disorder. All patients reported improvement or resolution of symptoms after botulinum toxin injection to the cricopharyngeus muscle. Adolescents with an inability to burp, reflux-like symptoms, bloating, and involuntary throat noises should be assessed for R-CPD by pediatric gastroenterologists with HRIM. The relatively recent recognition of this novel condition is the likely reason for its under- and misdiagnosis in children.

A Retrospective Study Evaluating Guideline Adherence of Neonatal Parenteral Nutrition in a Belgian Neonatal Intensive Care Unit.

Introduction Clinical nutrition for preterm and critically ill neonates remains a challenge. Preterms are often hemodynamically and metabolically compromised, which limits infusion volumes of nutrients and hinders achieving recommended nutrient intakes. While guidelines provide recommended ranges for parenteral nutrition (PN) intakes, they generally recommend enteral nutrition as soon as possible. Thus, in clinical practice, gradually increasing EN intakes complicates assessments of PN guideline adherence. Via a pragmatic approach, we assessed adherence to PN recommendations for macronutrients and energy as stated in the 2018 guidelines of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Methods In this retrospective study, we assessed the nutrition of preterm and critically ill term neonates from the neonatal intensive care unit of the University Hospital Brussels. We analyzed intakes for the first week of life, in which critically ill neonates at our center usually receive the majority of nutrients via PN. The PN-based provision of macronutrients and energy was analyzed descriptively in relation to the ESPGHAN 2018 recommendations. Results Macronutrients and energy provision gradually increased until they reached recommended or targeted values. Compared to term neonates, energy and lipid provision for preterms increased faster, while amino acid provision exceeded the ESPGHAN 2018 recommendations. Conclusions This study adds clinical practice data to the severely understudied field of the ESPGHAN 2018 PN guideline compliance. Using a pragmatic assessment of our nutrition protocols, we found the need to reduce the amount of amino acids per kg body weight per day to meet guideline recommendations.

The Effect of Polymorphisms and Other Biomarkers on Infliximab Exposure in Paediatric Inflammatory Bowel Disease: Development of a Population Pharmacokinetic Model.

Therapeutic drug monitoring (TDM) of infliximab has been shown to be a effective strategy for inflammatory bowel disease (IBD). Population pharmacokinetic (PopPK) modeling can predict trough concentrations for individualized dosing. The aim of this study was to develop a PopPK model of infliximab in a paediatric population with IBD, assessing the effect of single nucleotide polymorphisms (SNPs) and other biomarkers on infliximab clearance. This observational and ambispective single-centre study was conducted in paediatric patients with IBD treated with infliximab between July 2016 and July 2022 in the Paediatric Gastroenterology Service of the Hospital Universitari Vall d'Hebron (HUVH) (Spain). Demographic, clinical, and analytical variables were collected. Twenty SNPs potentially associated with variations in the response to infliximab plasma concentrations were analysed. infliximab serum concentrations and antibodies to infliximab (ATI) were determined by ELISA. PopPK modelling was performed using nonlinear mixed-effects analysis (NONMEM). Thirty patients (21 males) were included. The median age (range) at the start of infliximab treatment was 13 years (16 months to 16 years). A total of 190 samples were obtained for model development (49 [25.8%] during the induction phase). The pharmacokinetics (PK) of infliximab were described using a two-compartment model. Weight, erythrocyte sedimentation rate (ESR), faecal calprotectin (FC), and the SNP rs1048610 (ADAM17) showed statistical significance for clearance (CL), and albumin for inter-compartmental clearance (Q). Estimates of CL1 (genotype 1-AA), CL2 (genotype 2-AG), CL3 (genotype 3-GG), Q, Vc, and Vp (central and peripheral distribution volumes) were 0.0066L/h/46.4kg, 0.0055L/h/46.4kg, 0.0081L/h/46.4kg, 0.0029L/h/46.4kg, 0.6750L/46.4kg, and 1.19L/46.4kg, respectively. The interindividual variability (IIV) estimates for clearance, Vc, and Vp were 19.33, 16.42, and 36.02%, respectively. A popPK model utilising weight, albumin, FC, ESR, and the SNP rs1048610 accurately predicted infliximab trough concentrations in children with IBD.

Gluten-free diet adherence in pediatric celiac patients: Evaluating CDAT questionnaire and test for gluten detection in urine.

This study aimed to evaluate the contributions of the Adapted Celiac Dietary Adherence Test (CDAT) and the Rapid Urinary Gluten Detection Test (u-GIP) in assessing gluten-free diet adherence in children and adolescents with celiac disease. Fifty-four celiac patients from two pediatric gastroenterology outpatient clinics affiliated with university hospitals were evaluated. The original CDAT was adapted for children through a transcultural process, and the original cutoff point was adopted to define adherence. A single examiner carried out the u-GIP test in fresh urine samples. Sociodemographic and clinical factors and family food security status were also evaluated. A total of 88.9% of participants (confidence interval [CI]: 77.4-95.8; p<0.001) adhered to the gluten-free diet, as determined by the adapted CDAT score, while 87.0% (CI: 75.1-94.6; p<0.001) had negative u-GIP results. Among the 48 children adhering to the CDAT, six exhibited positive u-GIP results in a urine sample. Of the six nonadherent participants, only one had a positive u-GIP result. Notably, none of the children and adolescents with celiac disease who tested positive for u-GIP reported symptoms on the day of testing, and their growth rates remained stable. Even celiac children and adolescents adhering to the CDAT questionnaire may show a positive u-GIP in a single measurement without accompanying symptoms or growth impairment. The u-GIP could be helpful in complementary tests in specific situations, such as for patients who exhibit compliant behavior but still experience symptoms or maintain persistent positive serology.

Extensively Hydrolyzed Formula and Infant Colic Symptoms: Secondary Analysis of a Prospective Cohort Study.

Cow's milk protein allergy (CMPA) affects 2% to 3% of infants and is managed with hypoallergenic formulas. The 2022 recalls of infant formulas due to factors including contamination led to specialty formula shortages, highlighting CMPA management challenges. Understanding health care providers' (HCPs) decision-making in transitioning to alternative formulas during shortages is crucial. Limited attention has been given to how pediatric physicians make these choices. This study utilized US HCPs' de-identified survey data to assess driving factors when switching extensively hydrolyzed formulas during shortages. A total of 104 eligible HCPs participated, including general pediatrics, pediatric allergy/immunology, and pediatric gastroenterology specialists. Safety, tolerability, and efficacy were identified as top factors for switching formulas. Formula 1 was considered well-tolerated, patient-accepted, and safe by all HCPs. Most expressed strong belief in Formula 1's safety and effectiveness. Findings inform CMPA management during shortages, offering guidance to HCPs for suitable formula selection and enhanced infant care.

Pediatric inflammatory bowel disease: What's new and what has changed?

The incidence and prevalence of inflammatory bowel disease (IBD) is on the rise in North America and worldwide, with young children being the fastest growing patient population. It is therefore essential for pediatricians and pediatric sub-specialists to be able to recognize signs and symptoms suspicious for a new diagnosis of IBD, as well as potential complications associated with IBD or its treatment. This article reviews the most recent literature regarding clinical presentation, helpful diagnostic clues, newer monitoring tools being used by pediatric gastroenterologists, and emerging new biologic and small molecule treatments.
