Impact of Food Insecurity on Malnutrition Treatment Response in Nigerian Children With Sickle Cell Anemia and Severe Acute Malnutrition.

Background: In this planned ancillary analysis of our completed clinical trial, we hypothesized that among older children with sickle cell anemia (SCA) and severe acute malnutrition, those with higher levels of food insecurity would have lower end-of-trial body mass index (BMI) z-scores compared to their peers with SCA and lower levels of food insecurity.

Procedure: Data from 108 children who completed the feasibility trial for managing severe acute malnutrition in older children with SCA in Nigeria were analyzed. Children aged 5-12 years old with severe acute malnutrition (BMI z-score of <-3.

Diet management in congenital diarrheas and enteropathies - general concepts and disease-specific approach, a narrative review.

Congenital diarrheas and enteropathies (CODE) are a group of rare, heterogenous, monogenic disorders that lead to chronic diarrhea in infancy. Definitive treatment is rarely available, and supportive treatment is the mainstay. Nutritional management in the form of either specialized formulas, restrictive diet, or parenteral nutrition support in CODE with poor enteral tolerance is the cornerstone of CODE treatment and long-term growth.

Effects of Anterior Fundoplication on Postoperative Dysphagia and Reflux After Laparoscopic Esophagocardiomyotomy for Pediatric Achalasia.

Achalasia among children often fails endoscopic management (e.g., dilation, botulinum toxin).

A human milk oligosaccharide prevents intestinal inflammation in adulthood via modulating gut microbial metabolism.

Observational evidence suggests that human milk oligosaccharides (HMOs) promote the growth of commensal bacteria in early life and adulthood. However, the mechanisms by which HMOs benefit health through modulation of gut microbial homeostasis remain largely unknown. 2'-fucosyllactose (2'-FL) is the most abundant oligosaccharide in human milk and contributes to the essential health benefits associated with human milk consumption.

Impact of maternal depression on malnutrition treatment outcomes in older children with sickle cell anemia.

Background: Malnutrition and sickle cell anemia (SCA) result in high childhood mortality rates. Although maternal depression is an established risk factor for malnutrition in younger children, little is known about its impact on treatment response in children with malnutrition. We aimed to determine the relationship, if any, between maternal depression scores and malnutrition treatment outcomes in older children with SCA.

Identification of a functional peptide of a probiotic bacterium-derived protein for the sustained effect on preventing colitis.

Several probiotic-derived factors have been identified as effectors of probiotics for exerting beneficial effects on the host. However, there is a paucity of studies to elucidate mechanisms of their functions. p40, a secretory protein, is originally isolated from a probiotic bacterium, GG.

Risk factors in underweight older children with sickle cell anemia: a comparison of low- to high-income countries.

Previously, we demonstrated that older children with sickle cell anemia (SCA) living in Nigeria are at increased risk of death if they are underweight (weight-for-age z score < -1). We now conducted a cross-sectional study in low- and high-income settings to determine the risk factors for being underweight a in children aged 5 to 12 years with SCA. The children from low- and high-income settings were eligible participants for the Primary Prevention of Stroke in Children with Sickle Cell Disease in Nigeria (SPRING; N = 928) and the Silent Cerebral Infarct (SIT, North America/Europe; N = 1093) trials, respectively.

Epidemiology of Maternal Nutritional Status and Risk of Adverse Birth Outcomes in Undernourished Mothers with Sickle Cell Disease: A Systematic Review and Meta-Analysis Protocol.

In pregnancies complicated by sickle cell disease (SCD), the maternal-fetal dyad is at high risk for mortality and morbidity. In healthy pregnancies, maternal nutritional status is a critical factor for the healthy growth and development of the fetus. However, there are no reviews of the current research on the nutritional status of pregnant women with SCD and pregnancy outcomes.

Pediatric Aerodigestive Medicine: Advancing Collaborative Care for Children With Oropharyngeal Dysphagia.

Objectives: Aerodigestive disorders encompass various pathological conditions affecting the lungs, upper airway, and gastrointestinal tract in children. While advanced care has primarily occurred in specialty centers, many children first present to general pediatric gastroenterologists with aerodigestive symptoms necessitating awareness of these conditions. At the 2021 Annual North American Society for Pediatric Gastroenterology, Hepatology and Nutrition meeting, the aerodigestive Special Interest Group held a full-day symposium entitled, Pediatric Aerodigestive Medicine: Advancing Collaborative Care of Children with Aerodigestive Disorders.

Feasibility trial for the management of severe acute malnutrition in older children with sickle cell anemia in Nigeria.

Children with sickle cell anemia (SCA) living in Nigeria are at an increased risk of malnutrition, which contributes to increased morbidity and mortality. However, evidence-based guidelines for managing malnutrition in children with SCA are lacking. To address this gap, we conducted a multicenter, randomized controlled feasibility trial to assess the feasibility and safety of treating children with SCA aged from 5 to 12 years and having uncomplicated severe acute malnutrition (body mass index z score of <-3.

Fecal microbiota transplantation for the treatment of recurrent Clostridioides difficile (Clostridium difficile).

Background: Clostridioides difficile (formerly known as Clostridium difficile) is a bacterium that can cause potentially life-threatening diarrheal illness in individuals with an unhealthy mixture of gut bacteria, known as dysbiosis, and can cause recurrent infections in nearly a third of infected individuals. The traditional treatment of recurrent C difficile infection (rCDI) includes antibiotics, which may further exacerbate dysbiosis. There is growing interest in correcting the underlying dysbiosis in rCDI using of fecal microbiota transplantation (FMT); and there is a need to establish the benefits and harms of FMT for the treatment of rCDI based on data from randomized controlled trials.

Fecal transplantation for treatment of inflammatory bowel disease.

Background: Inflammatory bowel disease (IBD) is a chronic, relapsing disease of the gastrointestinal (GI) tract that is thought to be associated with a complex interplay between the immune system, the GI tract lining, the environment, and the gut microbiome, leading to an abnormal inflammatory response in genetically susceptible individuals. An altered composition of the gut's native microbiota, known as dysbiosis, may have a major role in the pathogenesis of ulcerative colitis (UC) and Crohn disease (CD), two subtypes of IBD. There is growing interest in the correction of this underlying dysbiosis using fecal microbiota transplantation (FMT).

Underweight children older than 5 years with sickle cell anemia are at risk for early mortality in a low-resource setting.

Undernutrition is a risk factor for under-5 mortality and is also postulated to be a risk factor for mortality in older children and adults with sickle cell anemia (SCA). We tested the hypothesis that underweight is associated with mortality in children aged 5 to 12 years with SCA. We performed a secondary analysis of participants in the Primary Prevention of Stroke in Children with Sickle Cell Disease in Nigeria trial, a double-blind, parallel-group randomized controlled trial for low-dose or moderate-dose hydroxyurea in children with abnormal transcranial Doppler velocities and a comparison group of participants with nonelevated transcranial Doppler velocities in northern Nigeria.

Multichannel magnetogastrogram: a clinical marker for pediatric chronic nausea.

Chronic nausea is a widespread functional disease in children with numerous comorbidities. High-resolution electrogastrogram (HR-EGG) has shown sufficient sensitivity as a noninvasive clinical marker to objectively detect distinct gastric slow wave properties in children with functional nausea. We hypothesized that the increased precision of magnetogastrogram (MGG) slow wave recordings could provide supplementary information not evident on HR-EGG.

Development and Validation of Web-Based Tool to Predict Lamina Propria Fibrosis in Eosinophilic Esophagitis.

Introduction: Approximately half of esophageal biopsies from patients with eosinophilic esophagitis (EoE) contain inadequate lamina propria, making it impossible to determine the lamina propria fibrosis (LPF). This study aimed to develop and validate a web-based tool to predict LPF in esophageal biopsies with inadequate lamina propria.

Methods: Prospectively collected demographic and clinical data and scores for 7 relevant EoE histology scoring system epithelial features from patients with EoE participating in the Consortium of Eosinophilic Gastrointestinal Disease Researchers observational study were used to build the models.

Automated Machine Learning Pipeline Framework for Classification of Pediatric Functional Nausea Using High-Resolution Electrogastrogram.

Objective: Pediatric functional nausea is challenging for patients to manage and for clinicians to treat since it lacks objective diagnosis and assessment. A data-driven non-invasive diagnostic screening tool that distinguishes the electro-pathophysiology of pediatric functional nausea from healthy controls would be an invaluable aid to support clinical decision-making in diagnosis and management of patient treatment methodology. The purpose of this paper is to present an innovative approach for objectively classifying pediatric functional nausea using cutaneous high-resolution electrogastrogram data.

Sex Moderates the Relationship Between Nausea Severity and Heart Rate Variability in Adolescents and Young Adults.

Background: Nausea is a common complaint among children and is particularly prevalent in children with functional abdominal pain (FAP), with nearly half of children with FAP also endorsing nausea. Dysfunction of the autonomic nervous system, which can be indexed by heart rate variability (HRV), leads to abnormalities in gastric electrical activity that are associated with GI symptoms.

Aims: To evaluate that relationship between nausea severity and HRV in adolescents and young adults with a history of FAP and to assess for sex differences.

Clinical Hypnosis in Pediatric Crohn's Disease: A Randomized Controlled Pilot Study.

Objective: The aim of this study was to implement clinical hypnosis (CH) as an adjunctive therapy for adolescents with Crohn's disease (CD) and to assess the impact of CH on quality of life (QoL), abdominal pain, psychosocial measures, and disease activity compared with standard care.

Methods: Forty adolescents with CD were randomized to a hypnosis intervention (HI) or waitlist control (WC) group. The intervention consisted of 1 in-person CH session, self-hypnosis education, and recordings for home practice.

Exposure to p40 in Early Life Prevents Intestinal Inflammation in Adulthood Through Inducing a Long-Lasting Epigenetic Imprint on TGFβ.

Background & Aims: Colonization by gut microbiota in early life confers beneficial effects on immunity throughout the host's lifespan. We sought to elucidate the mechanisms whereby neonatal supplementation with p40, a probiotic functional factor, reprograms intestinal epithelial cells for protection against adult-onset intestinal inflammation.

Methods: p40 was used to treat young adult mouse colonic (YAMC) epithelial cells with and without deletion of a methyltransferase, su(var)3-9, enhancer-of-zeste and trithorax domain-containing 1β (Setd1β), and mice in early life or in adulthood.

The effect of chronic nausea on gastric slow wave spatiotemporal dynamics in children.

Background: Chronic nausea in adolescents with functional gastrointestinal disorders is an increasingly reported but poorly understood symptom that negatively affects quality of life. Functional gastrointestinal disorders are known to correlate closely with slow wave rhythm disturbances. The ability to characterize gastric electrophysiologic perturbations in functional nausea patients could provide potential diagnostic and therapeutic tools for nausea patients.

Novel Insights Into Tissue-Specific Biochemical Alterations in Pediatric Eosinophilic Esophagitis Using Raman Spectroscopy.

Introduction: Elucidating esophageal biochemical composition in eosinophilic esophagitis (EoE) can offer novel insights into its pathogenesis, which remains unclear. Using Raman spectroscopy, we profiled and compared the biochemical composition of esophageal samples obtained from children with active (aEoE) and inactive EoE (iEoE) with non-EoE controls, examined the relationship between spectral markers and validated EoE activity indices.

Methods: In vitro Raman spectra from children with aEoE (n = 8; spectra = 51) and iEoE (n = 6; spectra = 48) and from non-EoE controls (n = 10; spectra = 75) were acquired.

Factors Associated With Adequate Lamina Propria Sampling and Presence of Lamina Propria Fibrosis in Children with Eosinophilic Esophagitis.

Background & Aims: Esophageal biopsies in children with eosinophilic esophagitis (EoE) are often inadequate for assessment of lamina propria and lamina propria fibrosis (LPF). For children with EoE, little is known about the factors associated with adequate lamina propria (aLP) sampling or the relationship among epithelial features in esophageal biopsies with and without LPF. We aimed to evaluate aLP in esophageal biopsies from children with and without EoE, identify factors associated with aLP and LPF, and examine the relationship among epithelial features in biopsies with and without LPF in children with EoE.
