Management of Ingested Foreign Bodies in Children: A Clinical Report of the NASPGHAN Endoscopy Committee

Abstract: Foreign body ingestions in children are some of the most challenging clinical scenarios facing pediatric gastroenterologists. Determining the indications and timing for intervention requires assessment of patient size, type of object ingested, location, clinical symptoms, time since ingestion, and myriad other factors. Often the easiest and least anxiety-producing decision is the one to proceed to endoscopic removal, instead of observation alone. Because of variability in pediatric patient size, there are less firm guidelines available to determine which type of object will safely pass, as opposed to the clearer guidelines in the adult population. In addition, the imprecise nature of the histories often leaves the clinician to question the timing and nature of the ingestion. Furthermore, changes in the types of ingestions encountered, specifically button batteries and high-powered magnet ingestions, create an even greater potential for severe morbidity and mortality among children. As a result, clinical guidelines regarding management of these ingestions in children remain varied and sporadic, with little in the way of prospective data to guide their development. An expert panel of pediatric endoscopists was convened and produced the present article that outlines practical clinical approaches to the pediatric patient with a variety of foreign body ingestions. This guideline is intended as an educational tool that may help inform pediatric endoscopists in managing foreign body ingestions in children. Medical decision making, however, remains a complex process requiring integration of clinical data beyond the scope of these guidelines. These guidelines should therefore not be considered to be a rule or to be establishing a legal standard of care. Caregivers may well choose a course of action outside of those represented in these guidelines because of specific patient circumstances. Furthermore, additional clinical studies may be necessary to clarify aspects based on expert opinion instead of published data. Thus, these guidelines may be revised as needed to account for new data, changes in clinical practice, or availability of new technology.

Why is initial bacterial colonization of the intestine important to infants' and children's health?

Abstract: Microbial colonization of the infant occurs during a critical time window for immune and gastrointestinal development. Infant colonization sets the stage for the adult microbiome. This review is a broad survey of the factors affecting infant colonization and the downstream effects on gastrointestinal health and disease. Major topics affecting colonization include initial inoculation dependent on birth mode, the impact of breast-feeding, and inside-out modulation of the developing microbiome by the immune system. Major outcomes of colonization include the timing-dependent education of the neonatal immune system, which is interconnected with barrier function and metabolism. These all engage in further continuing cross-talk with the microbiome, genetics, and nutrition. This review also briefly examines mechanisms of disease resulting from disrupted colonization as well as nutritional and microbial therapies.

Lipid Quality in Infant Nutrition: Current Knowledge and Future Opportunities.

Abstract: Dietary lipids are key for infants to not only meet their high energy needs but also fulfill numerous metabolic and physiological functions critical to their growth, development, and health. The lipid composition of breast milk varies during lactation and according to the mother's diet, whereas the lipid composition of infant formulae varies according to the blend of different fat sources. This report compares the compositions of lipids in breast milk and infant formulae, and highlights the roles of dietary lipids in term and preterm infants and their potential biological and health effects. The major differences between breast milk and formulae lie in a variety of saturated fatty acids (such as palmitic acid, including its structural position) and unsaturated fatty acids (including arachidonic acid and docosahexaenoic acid), cholesterol, and complex lipids. The functional outcomes of these differences during infancy and for later child and adult life are still largely unknown, and some of them are discussed, but there is consensus that opportunities exist for improvements in the qualitative lipid supply to infants through the mother's diet or infant formulae. Furthermore, research is required in several areas, including the needs of term and preterm infants for long-chain polyunsaturated fatty acids, the sites of action and clinical effects of lipid mediators on immunity and inflammation, the role of lipids on metabolic, neurological, and immunological outcomes, and the mechanisms by which lipids act on short- and long-term health.

Fecal Microbiota Composition of Breast-Fed Infants Is Correlated With Human Milk Oligosaccharides Consumed

Abstract: Objectives This study tested the hypothesis that the fecal bacterial genera of breast-fed (BF) and formula-fed (FF) infants differ and that human milk oligosaccharides (HMO) modulate the microbiota of BF infants.

Liver biopsy in children: position paper of the ESPGHAN Hepatology Committee.

Abstract: Liver biopsy (LB) is still the criterion standard procedure for obtaining liver tissue for histopathological examination and a valuable tool in the diagnosis, prognosis, and management of many parenchymal liver diseases. The aim of this position paper is to summarise the present practice of paediatric LB and make recommendations about its performance. Although histological evaluation of the liver is important in assessing prognosis and exploring treatment, noninvasive techniques (ie, imaging, laboratory markers) may replace use of liver histology. The indications for LB are changing as present knowledge of aetiologies, pathomechanism, and therapeutic options in paediatric liver disease is evolving. Adult and paediatric literature was reviewed to assess the existing clinical practice of LB with focus on the technique, indications, risk of complications, and contraindications in paediatrics. This position paper presents types of LB, indications, complications, contraindications, and an essential checklist for paediatric LB.

Prevalence and Health Outcomes of Functional Gastrointestinal Symptoms in Infants From Birth to 12 Months of Age

Abstract: Objectives: The aim of the study was to review published evidence and the opinion of practising clinicians on the prevalence and long-term health consequences of functional gastrointestinal symptoms in infants younger than 12 months. Methods: PubMed was searched from inception to November 2014 to find articles reporting the prevalence and long-term health outcomes of infantile colic, regurgitation, functional constipation, functional diarrhoea, and dyschezia in infants younger than <12 months. A questionnaire was sent to practising clinicians worldwide, and a group of 15 international experts met to discuss the likely frequency and longer-term consequences of these symptoms. Results: The literature search identified 30 studies reporting the prevalence of infantile colic (2%-73%), 13 that of regurgitation (3%-87%), 8 that of functional constipation (0.05%-39.3%), 2 that of functional diarrhoea (2%-4.1%), and 3 that of dyschezia (0.9%-5.6%). The studies varied in design, populations investigated, and definition of the symptoms. Questionnaires were received from 369 respondents. The experts agreed that the likely prevalences for colic, regurgitation, and functional constipation were 20%, 30%, and 15%, respectively. The limited data in the literature for functional diarrhoea and dyschezia suggest prevalences <10%. Infantile colic may be associated with future health problems in a subset of infants. Conclusions: Functional gastrointestinal symptoms appear to occur in a significant proportion of infants younger than 12 months and may have an impact on future health outcomes. Prospective collection of data according to agreed criteria is needed to obtain more accurate estimates of the prevalence and consequences of these symptoms.

Intestinal failure-associated liver disease: a position paper of the ESPGHAN Working Group of Intestinal Failure and Intestinal Transplantation.

Abstract: Intestinal failure-associated liver disease is the most prevalent complication affecting children with intestinal failure receiving long-term parenteral nutrition. This paper reviews the definition, diagnostic criteria, pathogenesis, and risk factors. The authors discuss the role of enteral nutrition, parenteral nutrition, and its components, especially lipid emulsions. The authors also discuss the surgical treatment, including intestinal transplantation, its indications, technique, and results, and emphasise the importance of specialised intestinal failure centres.

Indications and limitations of bariatric intervention in severely obese children and adolescents with and without nonalcoholic steatohepatitis: ESPGHAN Hepatology Committee Position Statement.

Abstract: Morbid obesity is strongly associated with nonalcoholic fatty liver disease (NAFLD), which is one of the most common causes of chronic liver disease worldwide. The present best treatment for NAFLD and nonalcoholic steatohepatitis (NASH) is weight reduction through lifestyle modification. Because of frustrating inefficiency of such a therapeutic approach, bariatric surgery is increasingly performed in adolescents as an alternative option for weight reduction. Standards of care and consensus for indications are, however, scarce. We explore the indications and limitations of bariatric surgery in children with severe obesity with and without NASH and aim to provide guidance for the exceptional indications for adolescents with extreme obesity with major comorbidity that may benefit from these controversial interventions. Present evidence suggests that bariatric surgery can decrease the grade of steatosis, hepatic inflammation, and fibrosis in NASH. Uncomplicated NAFLD is not an indication for bariatric surgery. Roux-en-Y gastric bypass is considered a safe and effective option for adolescents with extreme obesity, as long as an appropriate long-term follow-up is provided. Laparoscopic adjustable gastric banding has not been approved by the Food and Drug Administration for use in adolescents and therefore should be considered investigational. Finally, sleeve gastrectomy and other types of weight loss surgery that have grown increasingly common in adults, still need to be considered investigational. Temporary devices may be increasingly being used in pediatrics; however, future studies, including a long-term risk analysis of patients who undergo surgery, are much needed to clarify the exact indications for bariatric surgery in adolescents.

Fecal microbial transplant via nasogastric tube for active pediatric ulcerative colitis.

Abstract: Background Ulcerative colitis (UC), a chronic inflammatory disease of the large intestine, is characterized by a dysregulated immune reaction. UC is associated with fecal dysbiosis. Human and animal studies support the fact that the gastrointestinal microbiome may trigger the intestinal immune response, resulting in UC. Fecal microbial transplantation (FMT), by changing the gastrointestinal microbiome of patients with UC, may be a therapeutic option. Methods Four patients with moderate symptoms defined by the Pediatric Ulcerative Colitis Activity Index were enrolled in a prospective, open-label study of FMT via nasogastric tube in pediatric UC (US Food and Drug Administration IND 14942). After the donor and patient evaluation, patients received FMT with follow-up evaluations at 2, 6, and 12 weeks after transplantation. Study subjects were maintained on their pretransplant medications. The Pediatric Ulcerative Colitis Activity Index score, C-reactive protein, and stool calprotectin were completed during each study visit. Results Four patients with UC were enrolled (all boys). Ages ranged from 13 to 16 years. Patients tolerated FMT without adverse effects. None of the patients clinically improved with FMT, nor were there any significant changes in stool calprotectin or laboratory values, including C-reactive protein, albumin, and hematocrit. Three individuals received additional standard medical therapies before the end of the study. Conclusions This study, although showing that single-dose FMT via nasogastric tube is well tolerated in active pediatric UC, did not show any clinical or laboratory benefit.

Chlorpyrifos Exposure During Perinatal Period Affects Intestinal Microbiota Associated With Delay of Maturation of Digestive Tract in Rats.

Abstract: Objectives Pesticide exposure via residues in food may be especially harmful when it takes place in the developing child. The present study was designed to assess the impact of perinatal exposure to chlorpyrifos (CPF, an insecticide known to cross the placental barrier). Methods Female rats were exposed to oral CPF (1 or 5 mg kg day vs vehicle controls) from gestation onset up to weaning of the pups that were individually gavaged (CPF or vehicle) thereafter. Two developmental time points were studied: weaning (day 21) and adulthood (day 60). After sacrifice, samples from the intestinal tract and other organs underwent microbiological and histological analyses. Results Rat pups exposed to 5 mg kg day CPF were both significantly smaller (body length) and lighter than controls. Exposure to CPF was associated with changes in the histological structures (shorter and thinner intestinal villosities), an intestinal microbial dysbiosis, and increased bacterial translocation in the spleen and liver. These significant microbial changes in the gut were associated with impaired epithelium protection (mucin-2) and microbial pattern recognition receptor (Toll-like 2 and 4) gene expression. Conclusions Exposure to CPF during gestation and development affected the pups' intestinal development, with morphological alteration of the structures involved in nutrient absorption, intestinal microbial dysbiosis, alteration of mucosal barrier (mucin-2), stimulation of the innate immune system, and increased bacterial translocation. Perinatal exposure to CPF may therefore have short- and long-term impacts on the digestive tract.

Arsenic in rice: a cause for concern

Abstract: Inorganic arsenic intake is likely to affect long-term health. High concentrations are found in some rice-based foods and drinks widely used in infants and young children. In order to reduce exposure, we recommend avoidance of rice drinks for infants and young children. For all of the rice products, strict regulation should be enforced regarding arsenic content. Moreover, infants and young children should consume a balanced diet including a variety of grains as carbohydrate sources. Although rice protein-based infant formulas are an option for infants with cows' milk protein allergy, the inorganic arsenic content should be declared and the potential risks should be considered when using these products.

We aimed to investigate whether probiotics in pregnant and breast-feeding mothers altered the colonization pattern and the diversity of the mothers’ and children's i

Intestinal inflammation and impact on growth in children with cystic fibrosis.

Abstract: Objective: The aim of the study was to evaluate and compare faecal markers of intestinal inflammation in children with cystic fibrosis (CF), and determine whether intestinal inflammation adversely affects the nutritional phenotype. Methods: Faecal samples for markers of intestinal inflammation, calprotectin, S100A12, and osteoprotegerin, were collected from children with CF, healthy controls (HCs), and Crohn disease (CD). Associations between inflammatory markers and clinical and nutritional indices were determined in subjects with CF. Results: Twenty-eight children with CF (mean [standard deviation (SD)] 8.4 [3.3] years old, 22 pancreatic insufficient [PI]), 47 HC, and 30 CD were recruited. Mean (SD) faecal calprotectin in CF (94.3 [100.6] mg/kg) was greater than HC (26.7 [15.4] mg/kg, P < 0.0001), but lower than CD (2133 [2781] mg/kg, P ¼ 0.0003). Abnormal faecal calprotectin was found in subjects only with PI (17/22 (77%), P ¼ 0.001). There was no difference in faecal mean (SD) S100A12 (0.8 [0.9] vs 1.5 [2.2] mg/kg, P ¼ 0.14) and osteoprotegerin concentrations (72.7 [52.2] vs 62.5 [0.0] pg/mL, P ¼ 0.2) between CF and HC. Patients with CD had significantly elevated S100A12 and osteoprotegerin compared with CF and HC. Faecal calprotectin inversely correlated with both weight (r ¼� 0.5, P ¼ 0.003) and height z scores (r ¼� 0.6, P ¼ 0.002) in CF. Conclusions: The pattern of intestinal inflammation in CF is unique and distinct from inflammatory bowel disease, with elevated faecal calprotectin but normal faecal S100A12 and osteoprotegerin concentrations. The severity of intestinal inflammation, based on faecal calprotectin, significantly correlates with poor growth.

Biliary Atresia: Clinical Lessons Learned.

Abstract: Biliary atresia is a rare disease of unclear etiology, in which obstruction of the biliary tree causes severe cholestasis leading to cirrhosis and ultimately death if left untreated. Biliary atresia is the leading cause of neonatal cholestasis and the most frequent indication for pediatric liver transplantation. Any infant with persistent jaundice beyond 2 weeks of life needs to be evaluated for biliary atresia with fractionation of the bilirubin into conjugated and unconjugated portions. Early performance of a hepatoportoenterostomy in the first 45 days of life to restore bile flow and lessen further damage to the liver is thought to optimize outcome. Despite surgery, progressive liver scarring occurs, and 80% of patients with biliary atresia will require liver transplantation during childhood.

XII. Human Milk in Feeding Premature Infants: Consensus Statement.

Abstract: implications for the HPA axis (i.e., SLC6A4, that is gene encoding serotonin transporter). For example, in adults it has been documented a significant positive correlations between twin-twin differences in adiposity and DNA methylation at SLC6A4 in peripheral blood leukocytes (12). Furthermore, a study has documented that pain-related stress in NICU is associated with methylation status at SLC6A4 (13). These results suggest a new area of research in prematurity, that is exploring developmental and feeding behavior problems of preterm infants via epigenetics mechanisms, namely Preterm Behavioral Epigenetics (PBE) (6). In addition to the direct pathways through which early nutrition might affect risk of eating disorders, it would be interesting analyzing the interplay between early nutrition and stress in determining the epigenetic variations associated with feeding behavior problems.

Efficacy of Dietary Treatment for Inducing Disease Remission in Eosinophilic Gastroenteritis.

Abstract: Objectives Various dietary interventions have been used to treat patients with eosinophilic gastroenteritis (EGE). Concrete evidence as to the effectiveness of such treatments in inducing disease remission is, however, lacking. The aim of the study was to systematically review the efficacy of dietary therapies in inducing EGE remission. Methods We performed a systematic search for the MEDLINE, EMBASE, and SCOPUS libraries for studies investigating the efficacy of dietary interventions (in both histological and symptomatic remission) for children and adults with EGE and colitis. Results The search yielded 490 references; 30 were included in the review, with most of these references being "low-quality" individual cases or short case series. No significant publication bias was found. Elemental diets in children were linked to 75.8% of clinical improvement, but few of these patients underwent a histological evaluation. Allergy-testing results have been used scarcely in EGE. Empiric elimination of allergy-associated foods was the most commonly used option. The variable results in terms of symptom relief, however, were scarcely accompanied by histological confirmation. Clinical and methodological heterogeneity hindered the performance of quantitative summaries for the efficacy of dietary therapies in inducing disease remission. Conclusions Symptomatic improvements reported for dietary treatment in EGE by most of the available literature are questionable because of the lack of objective evaluation of clinical changes and the very limited assessment of histological remission. Because of the relative lack of well-designed, high-quality studies, the unequivocal use of dietary treatment for patients with EGE and colitis cannot be supported. Further research should be undertaken.

Novel risk factors for recurrent Clostridium difficile infection in children.

Fecal microbiota transplantation via nasogastric tube for recurrent clostridium difficile infection in pediatric patients.

Abstract: Fecal microbiota transplantation (FMT) is a safe and effective therapy for adults with recurrent Clostridium difficile colitis, but data regarding FMT in children are limited and focus on colonoscopic administration of FMT. We present 10 consecutive children who received FMT via nasogastric tube for treatment of recurrent C difficile infection. Median age was 5.4 years, and 30% were receiving simultaneous immunosuppression. Median follow-up was 44 days, and 90% of patients resolved their C difficile infection; one patient relapsed 2 months later after receiving antibiotics. FMT via nasogastric tube appears safe, well tolerated, and effective in treating pediatric recurrent C difficile colitis.

Refined Multidisciplinary Protocol-Based Approach to Short Bowel Syndrome Improves Outcomes.

Abstract: Objective Management of short bowel syndrome (SBS) has significantly evolved recently. We present our single-center, 25-year experience focusing on the implementation of a refined multidisciplinary SBS care protocol. Methods This is a retrospective review of the patients with SBS treated at our tertiary center from 1988 to 2014, with either 3 months. Patients with primary intestinal motility disorders were excluded. Clinical characteristics, including intestinal anatomy, markers of cholestasis, and catheter-related infections (CRIs), were analyzed. The implementation of a refined modern uniform management protocol in 2009 divided the cohort into 2 subgroups, whose outcomes are compared. Results Forty-eight patients with SBS were identified (median gestational age 33 weeks). Of them, 22 were born between 2009 and 2014. The main causes of SBS were necrotizing enterocolitis (46%) and midgut volvulus (23%). Median remaining small bowel length was 36 cm. The overall survival was 23 of 26 (88%) before 2009 and 21 of 22 (95%) thereafter, whereas none were transplanted. Duration of PN shortened from a median of 15 to 6 months (P = 0.0015) in the latter cohort, whereas frequency of autologous intestinal reconstruction surgery (31%) remained unchanged. Frequency of neonatal cholestasis was similar in both groups (75%), but cleared in all after 2009. Before 2009, 2 patients died of progressive cholestatic liver failure. The CRI rates decreased from 1.7 to 0.7 per 1000 catheter-days between 2000-2008 and 2009-2014, respectively (P = 0.0178). Conclusions Uniform refined multidisciplinary approach decreased the duration of PN and CRI rates with high transplant-free survival and avoidance of liver failure, although the frequency of transient neonatal cholestasis remained unchanged.

Diagnostic and Therapeutic Roles of Endoscopic Ultrasound in Pediatric Pancreaticobiliary Disorders.

Abstract: The diagnostic role of endoscopic ultrasound (EUS) in children has only recently been demonstrated, and that to a lesser extent than in adults. Data on the technique's therapeutic indications remains scarce. We therefore sought to evaluate diagnostic and interventional EUS indications, safety, and impact in children with pancreaticobiliary disorders.

Faecal calprotectin in suspected paediatric inflammatory bowel disease

Abstract: Objectives: The diagnostic accuracy of faecal calprotectin (FC) concentration for paediatric inflammatory bowel disease (IBD) is well described at the population level, but not at the individual level. We reassessed the diagnostic accuracy of FC in children with suspected IBD and developed an individual risk prediction rule using individual patient data. Methods: MEDLINE, EMBASE, DARE, and MEDION databases were searched to identify cohort studies evaluating the diagnostic performance of FC in paediatric patients suspected of having IBD. A standard study-level meta-analysis was performed. In an individual patient data meta-analysis, we reanalysed the diagnostic accuracy on a merged patient dataset. Using logistic regression analysis we investigated whether and how the FC value and patient characteristics influence the diagnostic precision. A prediction rule was derived for use in clinical practice and implemented in a spreadsheet calculator. Results: According to the study-level meta-analysis (9 studies, describing 853 patients), FC has a high overall sensitivity of 0.97 (95% confidence interval [CI] 0.92-0.99) and a specificity of 0.70 (0.59-0.79) for diagnosing IBD. In the patient-level pooled analysis of 742 patients from 8 diagnostic accuracy studies, we calculated that at an FC cutoff level of 50 mu g/g there would be 17% (95% Cl 15-20) false-positive and 2% (1-3) false-negative results. The final logistic regression model was based on individual data of 545 patients and included both FC level and age. The area under the receiver operating characteristic curve of this derived prediction model was 0.92 (95% CI 0.89-0.94). Conclusions: In high-prevalence circumstances, FC can be used as a noninvasive biomarker of paediatric IBD with only a small risk of missing cases. To quantify the individual patients' risk, we developed a simple prediction model based on FC concentration and age. Although the derived prediction rule cannot substitute the clinical diagnostic process, it can help in selecting patients for endoscopic evaluation.

Hepatic steatosis is prevalent in stillborns delivered to women with diabetes mellitus.

Abstract: Objective:Maternal diabetes is a risk factor for pregnancy complications, including stillbirth and macrosomia. Evolving data suggest that diabetes during pregnancy also has long-term consequences for offspring, putting them at risk for obesity and the metabolic syndrome in childhood. Because

Adrenal Suppression in Children Treated With Oral Viscous Budesonide for Eosinophilic Esophagitis.

Abstract: We sought to determine the prevalence of adrenal suppression (AS) in children with eosinophilic esophagitis treated with oral viscous budesonide (OVB). This was a retrospective review of a quality assurance initiative, whereby all children in our center treated with OVB for ≥3 months were referred over an 18-month time frame for endocrine assessment including 1 μg adrenocorticotropic hormone stimulation test. Fourteen of 19 children complied with the referral; of these 14 children, 6 (43%) had suboptimal stimulated cortisol (range 343-497 nmol/L, mean [±SD] 424.7 nmol/L [±52.4], normal ≥500 nmol/L). There was no significant association to treatment duration, dose, or concomitant use of inhaled/nasal corticosteroids. This study suggests that children treated with OVB may be at risk for AS.

Impact of Intestinal Rehabilitation Program and Its Innovative Therapies on the Outcome of Intestinal Transplant Candidates.

Abstract: Objectives The outcome of children with intestinal failure has improved during the past decade following the introduction of novel therapies by dedicated intestinal rehabilitation programs (IRP). The aim of the present study was to assess the impact of IRP on the outcome of intestinal transplant (IT) candidates and the transplant waiting list. Methods A retrospective cohort study of children assessed for IT (n = 84) during a 10-year period. Comparisons were made among the following 3 time periods: before the establishment of our center's IRP (1999-2002; n = 33), early IRP (2003-2005; n = 18), and late IRP (2006-2009; n = 33). The following endpoints were used: patient outcome following IT assessment (not listed, listed and removed from the list, received transplant, died while on the list), patient characteristics at IT assessment, and patient status at the end of the study. Results The late-IRP era was associated with an increase in patients who were not listed (42% vs 28% at other periods, P = NS) and patients who were removed from the IT waiting list because of clinical improvement (P 60% at other periods, P Conclusions Treatment by IRP, coupled with recent advances in the medical management of intestinal failure, is associated with improved survival and outcome of patients waiting for IT, and may lead to overall reduction in the number of IT in the future.

Accuracy of Nutritional Screening Tools in Assessing the Risk of Undernutrition in Hospitalized Children.

Abstract: Objective The aim of the present study was to evaluate the predictive accuracy of screening tools for assessing nutritional risk in hospitalized children in developed countries. Methods The study involved a systematic review of literature (MEDLINE, EMBASE, and Cochrane Central databases up to January 17, 2014) of studies on the diagnostic performance of pediatric nutritional screening tools. Methodological quality was assessed using a modified QUADAS tool. Sensitivity and specificity were calculated for each screening tool per validation method. A meta-analysis was performed to estimate the risk ratio of different screening result categories of being truly at nutritional risk. Results A total of 11 studies were included on ≥1 of the following screening tools: Pediatric Nutritional Risk Score, Screening Tool for the Assessment of Malnutrition in Paediatrics, Paediatric Yorkhill Malnutrition Score, and Screening Tool for Risk on Nutritional Status and Growth. Because of variation in reference standards, a direct comparison of the predictive accuracy of the screening tools was not possible. A meta-analysis was performed on 1629 children from 7 different studies. The risk ratio of being truly at nutritional risk was 0.349 (95% confidence interval [CI] 0.16-0.78) for children in the low versus moderate screening category and 0.292 (95% CI 0.19-0.44) in the moderate versus high screening category. Conclusions There is insufficient evidence to choose 1 nutritional screening tool over another based on their predictive accuracy. The estimated risk of being at "true nutritional risk" increases with each category of screening test result. Each screening category should be linked to a specific course of action, although further research is needed.
