Lysophosphatidylcholine-Rich Nutrition Therapy Increased Gut Absorption of Coingested Dietary Fat: a Randomized Controlled Trial.

Unintentional weight loss is common in persons with chronic and acute disease and is often caused by insufficient intake or malabsorption. A new lysophosphatidylcholine (LPC)-rich structured lipid powder has micelle-like activity that facilitates digestion and absorption, independent of lipase and bile acids. The aim of this secondary analysis was to determine if recycled LPC increased fat absorption of coingested food. Fasting plasma fatty acid (FA) concentrations were measured at baseline and 3 mo in children (n = 84) with cystic fibrosis and pancreatic insufficiency. Plasma palmitic acid was selected because of its dietary prevalence and was a minor component of the LPC product. Palmitic acid increased 15% in the LPC product-treated total subjects (P = 0.01) and 23% in the subgroup with more severe malabsorption (P = 0.007), with no change in either group on placebo. Total FAs increased 11% (P = 0.009) and 20% (P = 0.005), respectively. Increased palmitic acid and total FA suggest that LPC provided by the product created an intraluminal environment that increased coingested dietary fat absorption and provided more calories. This trial was registered at clinicaltrials.gov as NCT00406536.

Bone health in children with recurrent and chronic pancreatitis: A multi-center cross sectional analysis.

BACKGROUND/OBJECTIVES: Bone health of children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) is not well studied. METHODS: This retrospective study was performed at three sites and included data from INSPPIRE-2. RESULTS: Of the 87 children in the study: 46 had ARP (53%), 41 had CP (47%). Mean age was 13.6 ± 3.9 years at last DXA scan. The prevalence of low height-for-age (Z-score < -2) (13%, 10/78) and low bone mineral density (BMD) adjusted for height (Z-score < -2) (6.4%, 5/78) were higher than a healthy reference sample (2.5%, p < 0.0001 and p = 0.03, respectively). CONCLUSION: Children with ARP or CP have lower height and BMD than healthy peers. Attention to deficits in growth and bone mineral accrual in children with pancreatic disease is warranted.

Optimized Nutrition in Mitochondrial Disease Correlates to Improved Muscle Fatigue, Strength, and Quality of Life.

We sought to prospectively characterize the nutritional status of adults ≥ 19 years (n = 22, 27% males) and children (n = 38, 61% male) with genetically-confirmed primary mitochondrial disease (PMD) to guide development of precision nutritional support strategies to be tested in future clinical trials. We excluded subjects who were exclusively tube-fed. Daily caloric requirements were estimated using World Health Organization (WHO) equations to predict resting energy expenditure (REE) multiplied by an activity factor (AF) based on individual activity levels. We developed a Mitochondrial Disease Activity Factors (MOTIVATOR) score to encompass the impact of muscle fatigue typical of PMD on physical activity levels. PMD cohort daily diet intake was estimated to be 1,143 ± 104.1 kcal in adults (mean ± SEM, 76.2% of WHO-MOTIVATOR predicted requirement), and 1,114 ± 62.3 kcal in children (86.4% predicted). A total of 11/22 (50%) adults and 18/38 (47.4%) children with PMD consumed ≤ 75% predicted daily Kcal needs. Malnutrition was identified in 16/60 (26.7%) PMD subjects. Increased protein and fat intake correlated with improved muscle strength in those with insufficient daily Kcal intake (≤ 75% predicted); higher protein and fat intake correlated with decreased muscle fatigue; and higher protein, fat, and carbohydrate intake correlated with improved quality of life (QoL). These data demonstrate the frequent occurrence of malnutrition in PMD and emphasize the critical need to devise nutritional interventions to optimize clinical outcomes.

Nutrition association with skin integrity and pressure injury in critically ill pediatric patients.

BACKGROUND: Current research highlights the positive impact of nutrition therapy, particularly enteral nutrition, in critical illness. However, little attention is given to the impact of nutrition on skin integrity during critical illness. Skin integrity is at risk in critically ill children owing to necessary clinical therapies and challenges of providing nutrition therapy. METHODS: We conducted a narrative literature review with three main thematic concepts to drive our literature search: the association of nutrition therapy with (1) skin integrity; (2) injury, wounds, and wound healing; and (3) differences of skin color. Using pertinent search and subject terms, PubMed, CINAHL, EMBASE, and SCOPUS databases were searched, yielding 316 articles. After removal of duplicates, articles were reviewed based on inclusion and exclusion criteria defined by the authors; only eight articles met the defined criteria to inform this review. RESULTS: Large and important gaps exist in the current literature regarding an association between nutrition therapy, skin injury, and wound healing. Little to no attention was found for associations with skin color. The resulting narrative review addresses these topics and subtopics with additional references included that are independent of the original search strategy. CONCLUSIONS: A dearth of evidence exists describing associations between nutrition and disruption of skin integrity in pediatric critical illness. Children with dark skin are at increased risk, as manifestation and identification of disruption to skin integrity may not be recognized. Research is needed to describe these associations and the impact of nutrition on skin integrity, including differences of skin color.

The Role of the Mind-Body Connection in Children with Food Reactions and Identified Adversity: Implications for Integrating Stress Management and Resilience Strategies in Clinical Practice.

Child adversity is often associated with poor quality of life in pediatric gastrointestinal disorders, including non-allergic food reactions (food intolerances), which may be improved using mind-body interventions. We conducted an observational study to (1) describe child adversity (stressors) and resilience factors in children with food intolerances, and (2) explore the association between stressors and self-reported use of integrative modalities. A retrospective chart review of children ≥4-years-old presenting to a pediatric food intolerances clinic from 2017 to 2020 was performed (n = 130). Use of integrative medicine at intake, demographic, illness, and social history data were collected. Qualitative analysis identified exposure to stressors and resilience strategies. Correlation was assessed using a chi-square test. Management of the medical condition was the most common stressor, indicating impact on quality of life. Resilience strategies included themes of self-coping and social support. Individuals with one or more stressors were more likely to be using an integrative modality (most commonly, mind-body interventions) prior to their visit (X2 = 8.1, p = 0.004). Our hypothesis-generating study suggests that screening for child adversity and integrative medicine use may be used to better address quality of life and personalized approaches to treat pediatric food intolerances.

Updated clinical practice recommendations for managing adults with 22q11.2 deletion syndrome.

This review aimed to update the clinical practice guidelines for managing adults with 22q11.2 deletion syndrome (22q11.2DS). The 22q11.2 Society recruited expert clinicians worldwide to revise the original clinical practice guidelines for adults in a stepwise process according to best practices: (1) a systematic literature search (1992-2021), (2) study selection and synthesis by clinical experts from 8 countries, covering 24 subspecialties, and (3) formulation of consensus recommendations based on the literature and further shaped by patient advocate survey results. Of 2441 22q11.2DS-relevant publications initially identified, 2344 received full-text review, with 2318 meeting inclusion criteria (clinical care relevance to 22q11.2DS) including 894 with potential relevance to adults. The evidence base remains limited. Thus multidisciplinary recommendations represent statements of current best practice for this evolving field, informed by the available literature. These recommendations provide guidance for the recognition, evaluation, surveillance, and management of the many emerging and chronic 22q11.2DS-associated multisystem morbidities relevant to adults. The recommendations also address key genetic counseling and psychosocial considerations for the increasing numbers of adults with this complex condition.

Updated clinical practice recommendations for managing children with 22q11.2 deletion syndrome.

This review aimed to update the clinical practice guidelines for managing children and adolescents with 22q11.2 deletion syndrome (22q11.2DS). The 22q11.2 Society, the international scientific organization studying chromosome 22q11.2 differences and related conditions, recruited expert clinicians worldwide to revise the original 2011 pediatric clinical practice guidelines in a stepwise process: (1) a systematic literature search (1992-2021), (2) study selection and data extraction by clinical experts from 9 different countries, covering 24 subspecialties, and (3) creation of a draft consensus document based on the literature and expert opinion, which was further shaped by survey results from family support organizations regarding perceived needs. Of 2441 22q11.2DS-relevant publications initially identified, 2344 received full-text reviews, including 1545 meeting criteria for potential relevance to clinical care of children and adolescents. Informed by the available literature, recommendations were formulated. Given evidence base limitations, multidisciplinary recommendations represent consensus statements of good practice for this evolving field. These recommendations provide contemporary guidance for evaluation, surveillance, and management of the many 22q11.2DS-associated physical, cognitive, behavioral, and psychiatric morbidities while addressing important genetic counseling and psychosocial issues.

The Cellie Coping Kit for children with Eosinophilic Esophagitis: Feasibility, acceptability, and preliminary outcomes.

Children with eosinophilic esophagitis (EoE) are faced with ongoing treatments that can impact their wellbeing. There are no evidence-based resources that families can implement independently to cope with EoE-related stressors. This study aimed to examine acceptability, feasibility, and preliminary outcomes of the newly developed Cellie Coping Kit for Children with EoE intervention. Forty child-caregiver dyads completed a baseline assessment (T1) and initiated the intervention; 30 (75%) child participants and 33 (82.5%) caregivers were retained to follow-up (T2). Of those who completed the T2 assessment, most reported that the intervention was easy to use (>90%) and would recommend the intervention to others (>90%). The intervention was feasible: >70% used the kit, and most indicated they would use it again (>75%). More than half of families reported learning new information and/or coping strategies. No statistically significant changes were identified in comparing T1 and T2 coping and health-related quality of life. These findings suggest that the Cellie Coping Kit for Children with EoE is a promising intervention in that it was well accepted, feasible, and helped many families learn novel strategies on how to manage EoE challenges. Future research should examine how to strengthen the intervention to achieve longer-term targeted outcomes.

Presentations of children to emergency departments across Europe and the COVID-19 pandemic: A multinational observational study.

BACKGROUND: During the initial phase of the Coronavirus Disease 2019 (COVID-19) pandemic, reduced numbers of acutely ill or injured children presented to emergency departments (EDs). Concerns were raised about the potential for delayed and more severe presentations and an increase in diagnoses such as diabetic ketoacidosis and mental health issues. This multinational observational study aimed to study the number of children presenting to EDs across Europe during the early COVID-19 pandemic and factors influencing this and to investigate changes in severity of illness and diagnoses. METHODS AND FINDINGS: Routine health data were extracted retrospectively from electronic patient records of children aged 18 years and under, presenting to 38 EDs in 16 European countries for the period January 2018 to May 2020, using predefined and standardized data domains. Observed and predicted numbers of ED attendances were calculated for the period February 2020 to May 2020. Poisson models and incidence rate ratios (IRRs), using predicted counts for each site as offset to adjust for case-mix differences, were used to compare age groups, diagnoses, and outcomes. Reductions in pediatric ED attendances, hospital admissions, and high triage urgencies were seen in all participating sites. ED attendances were relatively higher in countries with lower SARS-CoV-2 prevalence (IRR 2.26, 95% CI 1.90 to 2.70, p < 0.001) and in children aged <12 months (12 to <24 months IRR 0.86, 95% CI 0.84 to 0.89; 2 to <5 years IRR 0.80, 95% CI 0.78 to 0.82; 5 to <12 years IRR 0.68, 95% CI 0.67 to 0.70; 12 to 18 years IRR 0.72, 95% CI 0.70 to 0.74; versus age <12 months as reference group, p < 0.001). The lowering of pediatric intensive care admissions was not as great as that of general admissions (IRR 1.30, 95% CI 1.16 to 1.45, p < 0.001). Lower triage urgencies were reduced more than higher triage urgencies (urgent triage IRR 1.10, 95% CI 1.08 to 1.12; emergent and very urgent triage IRR 1.53, 95% CI 1.49 to 1.57; versus nonurgent triage category, p < 0.001). Reductions were highest and sustained throughout the study period for children with communicable infectious diseases. The main limitation was the retrospective nature of the study, using routine clinical data from a wide range of European hospitals and health systems. CONCLUSIONS: Reductions in ED attendances were seen across Europe during the first COVID-19 lockdown period. More severely ill children continued to attend hospital more frequently compared to those with minor injuries and illnesses, although absolute numbers fell.

Gastrointestinal Features of 22q11.2 Deletion Syndrome Include Chronic Motility Problems From Childhood to Adulthood.

OBJECTIVES: 22q11.2 deletion syndrome (22q11.2DS) is the most common chromosomal microdeletion syndrome and has a multisystemic presentation including gastrointestinal features that have not yet been fully described. Our aim was to examine lifetime gastrointestinal problems in a large cohort of patients with 22q11.2DS. METHODS: All patients followed in the 22q and You Center at the Children's Hospital of Philadelphia (n = 1421) were retrospectively screened for: 1) age ≥ 17 years, 2) documented chromosomal microdeletion within the 22q11.2 LCR22A-LCR22D region, and 3) sufficient clinical data to characterize the adult gastrointestinal phenotype. Gastrointestinal problems in childhood, adolescence, and adulthood were summarized. Statistical association testing of symptoms against other patient characteristics was performed. RESULTS: Included patients (n = 206; 46% female; mean age, 27 years; median follow-up, 21 years) had similar clinical characteristics to the overall cohort. Genetic distribution was also similar, with 96% having deletions including the critical LCR22A-LCR22B segment (95% in the overall cohort). Most patients experienced chronic gastrointestinal symptoms in their lifetime (91%), but congenital gastrointestinal malformations (3.5%) and gastrointestinal autoimmune diseases (1.5%) were uncommon. Chronic symptoms without anatomic or pathologic abnormalities represented the vast burden of illness. Chronic symptoms in adulthood are associated with other chronic gastrointestinal symptoms and psychiatric comorbidities ( P < 0.01) but not with deletion size or physiologic comorbidities ( P > 0.05). One exception was increased nausea/vomiting in hypothyroidism ( P = 0.002). CONCLUSIONS: Functional gastrointestinal disorders (FGIDs) are a common cause of ill health in children and adults with 22q11.2DS. Providers should consider screening for the deletion in patients presenting with FGIDs and associated comorbidities such as neuropsychiatric illness, congenital heart disease, and palatal abnormalities.

Pancreatic Enzyme Replacement Therapy in Cystic Fibrosis.

While typically considered a pulmonary disease, cystic fibrosis patients develop significant nutritional complications and comorbidities, especially those who are pancreatic insufficient. Clinicians must have a high suspicion for cystic fibrosis among patients with clinical symptoms of pancreatic insufficiency, and pancreatic enzymatic replacement therapy (PERT) must be urgently initiated. PERT presents a myriad of considerations for patients and their supporting dieticians and clinicians, including types of administration, therapy failures, and complications.

Outpatient Pain Management in Children With Chronic Pancreatitis: A Scoping Systematic Review.

OBJECTIVES: Although pain management is central to pediatric chronic pancreatitis (CP) care, no evidence-based guidelines exist. In this scoping systematic review, we sought promising strategies for CP pain treatment in children. METHODS: We systematically reviewed literature on pain management in children and adults with CP, and 2 conditions with similar pain courses: juvenile idiopathic arthritis and sickle cell disease. RESULTS: Of 8997 studies identified, 287 met inclusion criteria. There are no published studies of analgesic medications, antioxidants, dietary modification, integrative medicine, or regional nerve blocks in children with CP. In adults with CP, studies of nonopioid analgesics, pancreatic enzymes, and dietary interventions have mixed results. Retrospective studies suggest that endoscopic retrograde cholangiopancreatography and surgical procedures, most durably total pancreatectomy with islet autotransplant, improve pain for children with CP. Follow-up was short relative to a child's life. Large studies in adults also suggest benefit from endoscopic therapy and surgery, but lack conclusive evidence about optimal procedure or timing. Studies on other painful pediatric chronic illnesses revealed little generalizable to children with CP. CONCLUSIONS: No therapy had sufficient high-quality studies to warrant untempered, evidence-based support for use in children with CP. Multicenter studies are needed to identify pain management "best practices."

Nutrition rehabilitation-related complications in primary mitochondrial disorders.

Primary mitochondrial disorders (PMDs) comprise a group of hundreds of individual genetic diseases affecting mitochondrial function, including oxidative phosphorylation and energy production. The estimated prevalence of these disorders ranges from 2.9 to 20 cases per 100,000. PMDs are commonly associated with malnutrition and growth failure. There is a paucity of literature regarding nutrition assessment and long-term data in the PMD population. We present three patients with various PMDs who presented complications related to malnutrition: (1) a 16-year-old male with Kearns-Sayre syndrome developed type 2 insulin-requiring diabetes mellitus after the initiation of high-calorie nutrition rehabilitation via gastrostomy tube (G-tube); (2) an 11-year-old female with myoclonic epilepsy associated with ragged red fibers developed diarrhea with metabolic decompensation and profound neurological and respiratory deterioration during nutrition rehabilitation after surgical G-tube placement; and (3) a 19-year-old male with a WARS2-associated PMD manifesting with developmental delay and severe parkinsonism presented complications related to poor wound healing after gastrojejunostomy tube placement. The last patient required prolonged hospitalization in the intensive care unit. Clinicians should be vigilant in monitoring these possible complications, as no standards of care exist for the initiation of enteral nutrition for this unique population.

A scoping review to inform a multi-disciplinary approach for nutrition therapy in critically ill children with pressure injuries.

Nutrition status plays a critical role in pressure injury (PI) healing and yet the available literature, especially in pediatric patients, is limited. Critically ill pediatric patients are at an increased risk of skin integrity compromise and PI development. Adequate nutritional intake can often be challenging to achieve in this population and immobility and illness present additional obstacles to maintaining skin integrity in this vulnerable population. Despite the unique nutritional challenges and needs of this group, there is no standardized approach to macro- and micronutrient management and monitoring. Here, several key vitamins and minerals believed to play a role in PI healing are discussed and an approach to nutritional management and monitoring for PI healing in pediatric patients is proposed. Registered dietitians (RD) are essential to assess individual patient macro and micronutrient requirements, to identify gaps and make recommendations to optimize nutritional therapy that may exist and impact wound healing. We used a scoping review to focus on the interplay of nutrition and PI healing and inform a multidisciplinary approach to PI identification and management. Through this review, we propose a strategy for the nutritional management of pediatric patients <30 kg at risk for and who present with PI.

A Comprehensive Analysis of the Genetic Diversity of Plasmodium falciparum Histidine-Rich Protein 2 (PfHRP2) in the Brazilian Amazon.

Early diagnosis and treatment are fundamental to the control and elimination of malaria. In many endemic areas, routine diagnosis is primarily performed microscopically, although rapid diagnostic tests (RDTs) provide a useful point-of-care tool. Most of the commercially available RDTs detect histidine-rich protein 2 (HRP2) of Plasmodium falciparum in the blood of infected individuals. Nonetheless, parasite isolates lacking the pfhrp2 gene are relatively frequent in some endemic regions, thereby hampering the diagnosis of malaria using HRP2-based RDTs. To track the efficacy of RDTs in areas of the Brazilian Amazon, we assessed pfhrp2 deletions in 132 P. falciparum samples collected from four malaria-endemic states in Brazil. Our findings show low to moderate levels of pfhrp2 deletion in different regions of the Brazilian Amazon. Overall, during the period covered by this study (2002-2020), we found that 10% of the P. falciparum isolates were characterized by a pfhrp2 deletion. Notably, however, the presence of pfhrp2-negative isolates has not been translated into a reduction in RDT efficacy, which in part may be explained by the presence of polyclonal infections. A further important finding was the discrepancy in the proportion of pfhrp2 deletions detected using two assessed protocols (conventional PCR versus nested PCR), which reinforces the need to perform a carefully planned laboratory workflow to assess gene deletion. This is the first study to perform a comprehensive analysis of PfHRP2 sequence diversity in Brazilian isolates of P. falciparum. We identified 10 PfHRP2 sequence patterns, which were found to be exclusive of each of the assessed regions. Despite the small number of PfHRP2 sequences available from South America, we found that the PfHRP2 sequences identified in Brazil and neighboring French Guiana show similar sequence patterns. Our findings highlight the importance of continuously monitoring the occurrence and spread of parasites with pfrhp2 deletions, while also taking into account the limitations of PCR-based testing methods associated with accuracy and the complexity of infections.

Feeding and nutrition in children with medical complexity.

Providing adequate and appropriate nutrition to children with medical complexity (CMC) is often a challenging task. These patients are a diverse group whose varying nutritional needs must be carefully assessed and monitored. Optimal feeding and nutrition strategies in CMC require an individual approach and may include oral, enteral (gastric or jejunal), or parenteral provision of nutrients. Complications of enteral feeding, including those associated with medical devices such as feeding tubes, are common, and provider familiarity with some of the more common complaints is helpful. We provide here a summary of different feeding approaches, with exploration of the rationale for each, as well as discussion of common complications and some practical troubleshooting tips.

Non-pharmacologic approach to pediatric constipation.

Functional constipation (FC) is a pervasive problem in pediatrics. Although pharmaceuticals are commonly used for FC, parents and patients show reluctance or find dissatisfaction with available medications at times. Further, patients often have interest in utilizing nutraceutical supplements and botanicals that are available over the counter. This literature review aims to summarize research studies performed on non-pharmacologic approaches to constipation and to evaluate the safety and efficacy of these modalities. Overall data on non-pharmacologic treatments for childhood constipation were sparse, and though some studies were available for adult populations, pediatrics studies were generally limited, lacking or flawed. Certain supplements, such as prebiotics, probiotics and fiber, are safe and are without significant side effects. Though fiber supplements such as glucomannan, green banana mass, cocao husk and various fiber blends have emerging evidence in children, evidence for psyllium, cellulose and flaxseed only have supportive studies in adults. Other than senna, studies of botanicals indicate significant safety concerns (in particular with Aloe vera with aloin and Cascara sagrada) and insufficient evidence. For patients with a significant behavioral or anxiety component to their FC and exhibit dyssynergia, mind-body interventions (e.g. diaphragmatic breathing, biofeedback, cognitive behavioral therapy, and behavioral modifications) are certainly safe and effective. Finally, movement and manipulative interventions such as abdominal massage, reflexology, acupuncture and transcutaneous nerve stimulation show promise in the field of pediatric constipation, and data is accumulating for efficacy. These modalities require further study to determine mechanisms of action and which populations may benefit the most from these therapies.

DIGEST: Developing innovative gastroenterology specialty training.

Individuals with cystic fibrosis (CF) now have an increased life expectancy, due to advances in care provided by a multidisciplinary team. The care model has expanded over time to include multiple subspecialties. The Cystic Fibrosis Foundation conducted a survey of Care Center Directors and identified a need for pediatric and adult gastroenterologists with expertise in the diagnosis and treatment of intestinal, pancreatic and hepatic complications of CF. To address this need, the Developing Innovative GastroEnterology Specialty Training (DIGEST) program was created. The development, implementation, and early results of this training program are reported herein.
