RESUMO
BACKGROUND: Long-term outcomes of congenital diarrheas and enteropathies (CODE) are poorly described. We evaluated the morbidity and mortality of children with CODE followed by an intestinal rehabilitation program (IRP) compared to children with short bowel syndrome (SBS). METHODS: Matched case-control study of children with intestinal failure (IF) due to CODE (diagnosed between 2006 and 2020; N = 15) and SBS (N = 42), matched 1:3, based on age at diagnosis and duration of parenteral nutrition (PN). Nutritional status, growth, and IF-related complications were compared. Survival and enteral autonomy were compared to a nonmatched SBS cohort (N = 177). RESULTS: Fifteen CODE patients (five males, median age 3.2 years) were followed for a median of 2.9 years. Eleven children were alive at the end of the follow-up, and two achieved enteral autonomy. The CODE group had higher median PN fluid and calorie requirements than their matched SBS controls at the end of the follow-up (83 vs. 45 mL/kg/day, p = 0.01; 54 vs. 30.5 kcal/kg/day, p < 0.01), but had similar rates of growth parameters, intestinal failure associated liver disease, central venous catheter complications and nephrocalcinosis. Kaplan-Meier analyses of 10-year survival and enteral autonomy were significantly lower in CODE patients compared to the nonmatched SBS population (60% vs. 89% and 30% vs. 87%, respectively; log-rank p < 0.008). CONCLUSIONS: Despite higher PN needs in CODE, rates of IF complications were similar to matched children with SBS. Enteral autonomy and survival rates were lower in CODE patients. Treatment by IRP can mitigate IF-related complications and improve CODE patient's outcome.

OBJECTIVES: Patients with short bowel syndrome-associated intestinal failure (SBS-IF) require long-term parenteral nutrition and/or intravenous fluids (PN/IV) to maintain fluid or nutritional balance. We report the long-term safety, efficacy, and predictors of response in pediatric patients with SBS-IF receiving teduglutide over 96 weeks. METHODS: This was a pooled, post hoc analysis of two open-label, long-term extension (LTE) studies (NCT02949362 and NCT02954458) in children with SBS-IF. Endpoints included treatment-emergent adverse events (TEAEs) and clinical response (≥20% reduction in PN/IV volume from baseline). A multivariable linear regression identified predictors of teduglutide response; the dependent variable was mean change in PN/IV volume at each visit over 96 weeks. RESULTS: Overall, 85 patients were analyzed; 78 patients received teduglutide in the parent and/or LTE studies (any teduglutide [TED] group), while seven patients did not receive teduglutide in either the parent or LTE studies. Most TEAEs were moderate or severe in intensity in both groups. By week 96, 82.1% of patients from the any TED group achieved a clinical response, with a mean fluid decrease of 30.1 mL/kg/day and an energy decrease of 21.6 kcal/kg/day. Colon-in-continuity, non-White race, older age at baseline, longer duration of teduglutide exposure, and increasing length of remaining small intestine were significantly associated with a reduction in mean PN/IV volume requirements. CONCLUSIONS: In pediatric patients with SBS-IF, teduglutide treatment resulted in long-term reductions in PN/IV requirements. The degree of PN/IV volume reduction depended on the duration of teduglutide exposure, underlying bowel anatomy, and demographics.

OBJECTIVES: Data on the relationship between body composition (BC) and physical activity (PA) in children with intestinal failure (IF) are lacking. The objectives were to collect data on PA and BC in children with IF, both parenterally and enterally fed, and to assess the relationship between PA and BC. METHODS: Cross-sectional study in children 5-18 years with IF including those receiving parenteral nutrition (PN) and those fully enterally fed. PA levels were measured using accelerometry. BC was measured by dual-energy X-ray absorptiometry. Data were compared to age- and sex-matched population norms using t tests. Regression analysis assessed the relationship between BC and PA. RESULTS: Fifty-eight children with IF (38 males), mean (SD) age of 10.0 (3.5) years, 20 dependent on PN were included. Patients with IF had significantly fewer steps per day ( P ≤ 0.001) compared with literature controls, with a mean (SD) of 7,972 (3,008) and 11,749 (1,106), respectively. There were no significant differences between patients receiving PN and those enterally fed, but both groups were significantly less active than literature controls ( P < 0.001). Patients with IF had higher fat mass and lower fat-free mass compared to literature controls ( P = 0.008). PA had a significant effect on BC ( r2 = 0.32, P < 0.001). CONCLUSIONS: Children with IF, those receiving PN and those fully enterally fed, are at risk of decreased PA and altered BC. PA should be part of ongoing rehabilitation and management to optimize outcomes.

OBJECTIVE: to determine diagnostic accuracy of an US-MRI clinical diagnostic pathway to detect appendicitis in the emergency department (ED). STUDY DESIGN: prospective cohort study of 624 previously healthy children 4-17 years old undergoing US for suspected appendicitis and clinical re-assessment. Children with non-diagnostic USs and persistent appendicitis concern/conclusive US-reassessment discrepancies underwent ultra-rapid MRI (US-MRI pathway), interpreted as positive, negative or non-diagnostic. Cases with missed appendicitis, negative appendectomies, and CT utilization were considered clinically diagnostically inaccurate. Primary outcome was the proportion of accurate diagnoses of appendicitis/lack thereof by the pathway. RESULTS: 150/624 (24%) children had appendicitis;255 USs (40.9%) were non-diagnostic. Of 139 US-MRI pathway children (after 117 non-diagnostic and 22 conclusive USs), 137 [98.6%; 95% CI 0.96-1.00] had clinically accurate outcomes (1 CT, 1 negative appendectomy): sensitivity 18/18 [100%], specificity 119/121 [98.3%], positive predictive value 18/20 [90.5%], negative predictive value 119/119 [100%]. MRI imaging accuracy was 134/139 (96.4%); 3 MRIs were non-diagnostic (no appendicitis). In the overall algorithm, 616/624 [98.7% (0.97-0.99)] patients had accurate outcomes: 147/150 (98.0%) appendicitis cases had confirmatory surgeries (3 CTs) and 469/474 (98.9%) appendicitis-negative children had no surgery/CT. CONCLUSION: this study demonstrated high clinical accuracy of the US-rapid-MRI pathway in suspected pediatric appendicitis after non-diagnostic US.

OBJECTIVES: Despite a focus on neurocognition in pediatric intestinal failure (IF) to date, we examined social-emotional and adaptive functioning. METHODS: Children (N = 63) in our IF rehabilitation program underwent neuropsychological assessments including caregiver- and teacher-reported questionnaires. Results were compared to norms using z-tests. Caregiver and teacher reports were compared using t tests. Medical and demographic factors were examined in an exploratory manner using correlation and targeted regression analyses, adjusting for gestational age and full-scale IQ. RESULTS: Caregiver and teacher reports indicated poorer executive, internalizing, behavioral, and adaptive functioning compared to norms. Teachers reported more executive dysfunctions than caregivers. Necrotizing enterocolitis diagnosis predicted internalizing emotional problems. Immigrant status predicted poorer social and practical adaptive functioning. Living with biological parents predicted fewer externalizing emotional and behavioral problems. CONCLUSIONS: The group displayed social-emotional and adaptive functioning concerns. Identifying medical and demographic risks can allow for screening and intervention.

Deciding which patients would benefit from intestinal transplantation (IT) remains an ethical/clinical dilemma. New criteria* were proposed in 2015: ≥2 intensive care unit (ICU) admissions, loss of ≥3 central venous catheter (CVC) sites, and persistently elevated conjugated bilirubin (CB ≥ 75 µmol/L) despite 6 weeks of lipid modification strategies. We performed a retrospective, international, multicenter validation study of 443 children (61% male, median gestational age 34 weeks [IQR 29-37]), diagnosed with IF between 2010 and 2015. Primary outcome measure was death or IT. Sensitivity, specificity, NPV, PPV, and probability of death/transplant (OR, 95% confidence intervals) were calculated for each criterion. Median age at IF diagnosis was 0.1 years (IQR 0.03-0.14) with median follow-up of 3.8 years (IQR 2.3-5.3). Forty of 443 (9%) patients died, 53 of 443 (12%) were transplanted; 11 died posttransplant. The validated criteria had a high predictive value of death/IT; ≥2 ICU admissions (p < .0001, OR 10.2, 95% CI 4.0-25.6), persistent CB ≥ 75 µmol/L (p < .0001, OR 8.2, 95% CI 4.8-13.9). and loss of ≥3 CVC sites (p = .0003, OR 5.7, 95% CI 2.2-14.7). This large, multicenter, international study in a contemporary cohort confirms the validity of the Toronto criteria. These validated criteria should guide listing decisions in pediatric IT.

OBJECTIVE: To measure the time that caregivers spend on tasks related to providing care to their child with intestinal failure receiving home parenteral nutrition (PN). STUDY DESIGN: We conducted an exploratory cross-sectional study of caregivers of children with intestinal failure receiving long-term PN followed by our intestinal rehabilitation program. Caregivers completed a daily diary of care-related tasks. Data were analyzed using descriptive statistics. Exploratory models were completed to evaluate factors that influenced the amount of time that caregivers spent providing care. SAS University Edition 2018 (SAS Institute, Cary, NC) was used for data analysis with a P value of less than .05 considered significant. RESULTS: Thirty-four caregivers of children with intestinal failure consented with response rates of 85%. The mean age of the primary caregiver was 37 ± 7.9 years of age with 97% being the child's mother. The median PN exposure was 1239 days (IQR, 432-3012). Caregivers reported a median of 29.2 hours per week (IQR, 20.8-45.7 hours per week) of direct medical care. The majority of time was spent on providing PN and care of the central venous catheter (6.1 hours; IQR, 5.2-8.8). CONCLUSIONS: Caregivers of children with intestinal failure receiving long-term PN provide a significant amount of care to ensure their child remains healthy at home. The most significant amounts of time were spent on the administration of the PN and care of the central venous catheter.

OBJECTIVES: With increasing number of children with intestinal failure (IF) on long-term parenteral nutrition (PN), this study assesses the impact of IF on muscle strength, speed, and agility and body composition (BC), identifying clinical factors that may predict impairment. METHODS: Cross-sectional study in children 5-18 years with IF on PN. Assessments included Bruininks-Oseretsky Test of Motor Proficiency-2 strength and agility subtest (BOT-2), and grip strength. BC data from dual-energy x-ray absorptiometry (DXA) measurements and clinical variables were collected by chart abstraction. Data were compared to age and sex matched controls and population norms. RESULTS: Twenty-one children with IF (14 males), median age 8.33 (IQR: 6.96-11.04) years and 33 controls (20 males), 8.25 (6.67-10.79) years were included. Strength and agility ( P < 0.001) and grip strength ( P = 0.001) differed between groups. Nine of 21 (43%) of children with IF scored >1 standard deviation (SD) below mean on BOT-2 and 13 of 21 (62%) had grip strength >1 SD below mean. DXA measurements showed 10 of 18 (56%) of children had lower fat-free mass (FFM)% and higher fat mass (FM)% than reference norms. Decreased FFM% was associated with lower BOT-2 scores ( r = 0.479; P = 0.044) and grip strength scores >1 SD below mean ( P = 0.047). Additional clinical factors significantly impacting strength and agility included prematurity, height, hospitalizations, sepsis, and small bowel length. CONCLUSIONS: Children with IF are at risk of decreased muscle strength and agility, along with altered BC. Ongoing medical, nutritional, and rehabilitation intervention is vital to optimize outcomes.

BACKGROUND AND AIMS: The initial description of a heterozygous dominant ACTG2 variant in familial visceral myopathy was followed by the identification of additional variants in other forms of intestinal dysmotility disorders. we aimed to describe the diverse phenotype of this newly reported and rare disease. METHODS: Report of 4 new patients, and a systematic review of ACTG2-related disorders. we analyzed the population frequency and used in silico gene damaging predictions. Genotype-phenotype correlations were explored. RESULTS: One hundred three patients (52% girls), from 14 publications, were included. Twenty-eight unique variants were analyzed, all exceedingly rare, and 27 predicted to be highly damaging. The median Combined Annotation Dependent Depletion (CADD) score was 29.2 (Interquartile range 26.3-29.4). Most patients underwent abdominal surgery (66%), about half required intermittent bladder catheterization (48.5%), and more than half were parenteral nutrition (PN)-dependent (53%). One-quarter of the patients died (25.7%), and 6 required transplant (5.8%). Girls had a higher rate of microcolon (Pâ =â0.009), PN dependency (Pâ=â0.003), and death/transplant (Pâ=â0.029) compared with boys, and early disease onset (<2âyears of age) was associated with megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) features. There was no statistical association between disease characteristics and CADD scores. CONCLUSIONS: Damaging ACTG2 variants are rare, often associated with MMIHS phenotype, and overall have a wide phenotypic variation. Symptoms usually present in the perinatal period but can also appear at a later age. The course of the disease is marked by frequent need for surgical interventions, PN support, and mortality. Poor outcomes are more common among girls with ACTG2 variants.

OBJECTIVES: To assess the natural history and outcomes of children with intestinal failure in a large, multicenter, geographically diverse contemporary cohort (2010-2015) from 6 pediatric intestinal failure programs. STUDY DESIGN: Retrospective analysis of a multicenter intestinal failure cohort (n = 443). Competing-risk analysis was used to obtain cumulative incidence rates for the primary outcome (enteral autonomy, transplantation, or death). The χ2 test and Cox proportional hazard regression were used for bivariate and multivariable analyses. RESULTS: The study cohort comprised 443 patients (61.2% male). Primary etiologies included short bowel syndrome (SBS), 84.9%; dysmotility disorder, 7.2%; and mucosal enteropathy, 7.9%. Cumulative incidences for enteral autonomy, transplantation, and death at 6 years of follow-up were 53.0%, 16.7%, and 10.5%, respectively. Enteral autonomy was associated with SBS, ≥50% of small bowel length, presence of an ileocecal valve (ICV), absence of portal hypertension, and follow-up in a non-high-volume transplantation center. The composite outcome of transplantation/death was associated with persistent advanced cholestasis and hypoalbuminemia; age <1 year at diagnosis, ICV, and intact colon were protective. CONCLUSIONS: The rates of death and transplantation in children with intestinal failure have decreased; however, the number of children achieving enteral autonomy has not changed significantly, and a larger proportion of patients remain parenteral nutrition dependent. New strategies to achieve enteral autonomy are needed to improve patient outcomes.

BACKGROUND: Previous studies in piglets show a direct relationship between intestinal mass and arginine (Arg) synthesis. We aimed to study the effects of 75% intestinal resection on whole-body Arg synthesis. METHODS: Piglets were allocated to sham or jejunocolic (JC) surgery and to enteral nutrition (EN) at 20% [sham (n = 8), JC (n = 10)], or 40% [sham (n = 4), JC (n = 5)]. A gastric tube was placed for EN and a venous catheter for parenteral nutrition and blood sampling. On day 6, a primed bolus and constant infusion of Arg m + 2 label and proline m + 1 label was delivered. In addition, 40% EN piglets received a citrulline (Cit) m + 3 tracer. Blood sampling was undertaken and whole-body Arg synthesis was calculated. On day 7, intestinal length was measured, and samples were collected for gene expression (PCR quantification) and histopathology. RESULTS: On Day 7, sham piglets showed intestinal lengthening compared to JC (p = 0.02). Whole-body Arg synthesis was similar between groups (p = 0.50). Adjusting for absolute small intestinal length, JC piglets had greater Arg synthesis (p = 0.01). Expression of arginosuccinase was upregulated in the jejunum of JC compared to sham on 20% EN (p = 0.03). CONCLUSION: This demonstrates for the first-time adaptive changes in intestinal Arg synthesis following intestinal resection. IMPACT: The intestine makes a critical contribution to whole-body arginine synthesis, particularly in neonates, a human population at risk for short bowel syndrome. Therefore, we studied intestinal arginine synthesis in a neonatal piglet model of short bowel syndrome and demonstrated adaptive changes in the intestine that may preserve whole-body arginine synthesis, despite loss of intestinal mass. This research adds new information to our understanding of the effects a massive intestinal resection has on amino acid metabolism during neonatal development.

OBJECTIVES: With improved survival of children with intestinal failure (IF), it is important to examine the impact on long-term physical function, physical activity (PA), and fatigue and identify clinical factors that may be predictive of impairment. METHODS: Cross-sectional study in children with IF on parenteral nutrition (PN) compared with healthy age- and sex-matched controls (HCs). Assessments included: Paediatric Quality of Life (PedsQL) Physical Function subscale, PedsQL Multi-Dimensional Fatigue Scale, and PA Perceived Benefits and Barriers scale. PA was measured using an accelerometer. Medical data was collected by chart abstraction. RESULTS: Participants included 21 children with IF (14 girls), median age 8.33 (interquartile range [IQR] 6.96-11.04) years and 33 HCs (20 boys), 8.25 (6.67-10.79) years. In those with IF, 13 (62%) were born prematurely with a median of 15 (7.5-24.5) in-patient hospitalizations. There was a significant difference (Pâ=â0.033) in mean steps/day in children with IF (9709â+/-â3975) compared with HCs (13104â+/-â5416), and a correlation between moderate-to-vigorous PA and gestational age (râ=â0.642, Pâ=â0.010). Child and parent proxy scores indicate poorer physical function and greater fatigue in the IF group, along with a correlation between greater fatigue (râ=â-0.538, Pâ=â0.012), poorer physical function (râ=â-0.0650, Pâ=â0.0001) in children with more hospitalizations. Barriers to PA include "I am tired" and "I am worried about my line." CONCLUSIONS: Children with IF present with lower levels of PA and physical function and greater fatigue compared with their peers. Ongoing development of medical and rehabilitation intervention strategies is vital to optimize outcomes.

OBJECTIVE: Gastrointestinal dysmotility is common in patients with pediatric intestinal failure (PIF), leading to delays in advancement of enteral nutrition (EN). Few studies have been published regarding the safety and efficacy of cisapride for improvement of enteral tolerance and ability to wean parenteral nutrition. Our objective was to describe a single center experience on the use of cisapride in patients with PIF. METHODS: Retrospective chart review of patients was performed. Demographic, intestinal anatomy, and outcome data were collected. Percentage of EN before initiation of cisapride, progression of EN at 3 and 6 months, and ability to wean parenteral nutrition after initiation of cisapride were calculated. RESULTS: Prokinetics were used in 61 of 106 patients (56.6%); 29 of 60 patients (48.3%) failed to progress EN on other prokinetics and started on cisapride. Before cisapride the progress of EN plateaued for a mean of 42.3 (standard deviation [SD] 60.2) days. The rate of feed progression was 0.14% (SD 0.19)/day pre-cisapride and 0.69%/day (SD 0.31) after cisapride initiation (Pâ<â0.001). Percentage of EN improved significantly from baseline to 3 months postinitiation (23.9% vs 79.4%, respectively; Pâ<â0.001). Electrocardiogram was performed on initiation of cisapride and after every dose change. Medication was discontinued in 2 of 29 (6.8%). CONCLUSION: This retrospective study suggests that cisapride may be beneficial in PIF patients who fail to progress EN on first line prokinetics. The most significant period of improvement occurs within 3 months of cisapride initiation. Cardiac side effects in our cohort were lower than previously reported; however, cardiac monitoring is still recommended.

Currently, in North America we are fortunate to have a number of available options for lipid emulsions to be used in the parenteral nutrition regimens for infants and children, including for long-term parenteral nutrition given intestinal failure. Neonates and infants in particular are at risk for intestinal failure-associated liver disease (IFALD). The choice of parenteral lipid emulsion will influence the risk and severity of IFALD. The purpose of this review is to discuss the rationale for the composite lipid emulsion SMOFlipid that includes soybean, medium-chain triglycerides, olive and fish oils for IFALD, with focus on the Canadian practice and experience.

BACKGROUND: Outcomes of pediatric intestinal failure (PIF) have improved recently, with other comorbidities, such as increased echogenicity/nephrocalcinosis on ultrasound (US) in long-term survivors now evident. We evaluated the significance of nephrocalcinosis over time in PIF and its impact on renal function. METHODS: Retrospective analysis on a cohort of PIF patients was performed. Presence of nephrocalcinosis and/or increased renal echogenicity (identified on US), estimated glomerular filtration rate (eGFR; mlâ·âminâ·â1.73âm2), renal tubular function, PN volume (mlâ·âkgâ·âday) and PN exposure time (hours/day) were reviewed annually over a follow-up period of 2 years. Outcomes in the nephrocalcinosis versus normal US groups were compared. RESULTS: Forty patients (28 boys, median age 2.7 years) were followed for 2 years. Fifteen (38%) had either increased echogenicity or nephrocalcinosis (group 1) at initial US. US were normal in the remaining 25 (62%) on initial assessment (group 2). eGFR did not differ between group 1 and group 2 at baseline (118 vs 133, Pâ=â0.51) and year 2 (130 vs 131, Pâ=â1.00). The percentage of patients with abnormal markers of tubular function was similar in both groups at year 2 (high urine calcium: creatinine 33 versus 30, Pâ=â0.83; high urine calcium: citrate 39 versus 42, Pâ=â0.87; low urine citrate: creatinine 15 versus 17, Pâ=â1.00; high urine oxalate: creatinine 39 versus 25, Pâ=â0.77). CONCLUSIONS: A large proportion of PIF patients with a history of parenteral nutrition (PN) exposure have nephrocalcinosis and/or increased echogenicity on US. Over a 2-year follow-up period, however, these abnormalities had no impact on eGFR or renal tubular function.

OBJECTIVES: Little is known about school-age functioning in children with intestinal failure (IF). This study examines neurocognitive outcomes of children with IF at ages 4 to 8 years treated at a single centre, along with relevant medical and demographic variables. METHODS: Between 2012 and 2016, neurocognitive assessments were administered to 28 children receiving treatment in our IF rehabilitation program, and included measures of intelligence, academics, learning/memory, language, visual-motor integration, and fine-motor dexterity. DSM-IV/V criteria were used to diagnose Learning Disability, Intellectual Disability, and/or Attention Deficit/Hyperactivity Disorder. RESULTS: Intellectual functioning ranged from extremely low to superior (Full Scale IQ range 53-123, meanâ=â89). Forty-six percentage received a cognitive/learning DSM diagnosis. Total number of first-year septic episodes correlated with poorer outcomes on the most cognitive measures. Adjusting for gestational age (61% were born <37 weeks), number of first-year septic episodes negatively predicted working memory, visual-motor integration, and visual memory scores. Additional factors correlating with poorer outcomes on ≥2 cognitive measures included length of first-year admissions, necrotizing enterocolitis diagnosis, and first-year sustained conjugated hyperbilirubinemia. Having ≥2 first-year septic episodes increased the likelihood of poorer outcome. Having a sibling was a significant positive predictor of working memory, processing speed, reading, and verbal learning skills. CONCLUSIONS: Our data provides preliminary evidence that children with IF are at risk of neurocognitive problems at early school age. Managing septic events during the first year is one strategy that may help reduce long-term neurocognitive risks in this population.

OBJECTIVES: Short bowel syndrome (SBS) remains the leading cause of neonatal intestinal failure. Milk fat globule epidermal growth factor-8 (MFG-E8), present in human milk, has homology with epidermal growth factor (EGF), known to enhance adaptation in SBS. In this pilot study, the role of oral MFG-E8 treatment in SBS was explored in neonatal piglets. METHODS: Neonatal piglets underwent 75% intestinal resection, either distal (jejunal-colonic [JC] anastomosis) or mid-intestinal (jejunal-ileal [JI] anastomosis). Piglets were randomized to intragastric treatment with MFG-E8 â(5âmg/kg per day) or saline and were maintained on parenteral nutrition and enteral nutrition for 7 days. Adaptation was assessed by intestinal length and weight, histopathology, fecal fat analysis and RT-qPCR analysis of mucosal transcripts, including growth factors. RESULTS: JI piglets demonstrated intestinal lengthening (Pâ<â0.001), 2-fold greater in ileum than jejunum (Pâ=â0.02), where lengthening was increased by MFG-E8 treatment (Pâ=â0.02). JC piglets did not exhibit jejunal lengthening, regardless of treatment. Fat absorption was greater for JI piglets (Pâ=â0.02), unaffected by treatment. In JI piglets, expression of Egf was increased in the ileum (Pâ<â0.01) and MFG-E8 treatment increased Egfr (receptor) expression (Pâ=â0.02). CONCLUSIONS: MF-EG8 demonstrated site-specific trophic effects, only with JI anatomy. This may limit the utility of this treatment for SBS, except for rare patients with retained ileum. The mechanisms of these site-specific effects, however, and the role of MFG-E8 in neonatal gut growth and in diseases, such as necrotizing enterocolitis that commonly target ileum, warrant further exploration.

PURPOSE: With reduced mortality of neonatal conditions, health-related quality of life (HRQOL) has become an important clinical outcome. However, since the meaning of HRQOL in dependent, non-autonomous infants and neonates remains largely undefined, HRQOL measurement and economic evaluation are limited due to the lack of age-specific methodology. The objective was to construct a conceptual framework of neonatal and infant HRQOL (NIHRQOL) which identifies factors relevant to the neonate and infant, their relationship with each other and the caregiving environment. METHODS: Using qualitative methods, a concept was developed based on in-depth analysis of verbatim records of two focus groups (6 caregivers, 6 healthcare providers) and five interviews with caregivers of chronically ill neonates/infants (n = 2), and healthcare professionals of a pediatric tertiary healthcare center (n = 3). Two analysts independently performed thematic analysis using an inductive and contextual approach. RESULTS: The majority of participants regarded NIHRQOL as an individual entity, which was closely related and strongly influenced by caregivers and family. It may be gauged by the perceived degree of effort required to achieve expected normalcy in everyday life for the neonate/infant and its family. The importance of individual HRQOL factors is developmental stage-dependent. CONCLUSION: Neonatal and infant HRQOL is a multidimensional, multilayered and interconnected concept, where the child's needs contribute most directly, and the caregiver's and society's ability to meet those needs characterize the interdependence between the child and its caregiving environment. Developmental stage-specific HRQOL instruments for premature and mature neonates, and infants are warranted to allow for valid HRQOL measurement.

BACKGROUND: Enhanced Recovery After Surgery (ERAS®) Society guidelines integrate evidence-based practices into multimodal care pathways that have improved outcomes in multiple adult surgical specialties. There are currently no pediatric ERAS® Society guidelines. We created an ERAS® guideline designed to enhance quality of care in neonatal intestinal resection surgery. METHODS: A multidisciplinary guideline generation group defined the scope, population, and guideline topics. Systematic reviews were supplemented by targeted searching and expert identification to identify 3514 publications that were screened to develop and support recommendations. Final recommendations were determined through consensus and were assessed for evidence quality and recommendation strength. Parental input was attained throughout the process. RESULTS: Final recommendations ranged from communication strategies to antibiotic use. Topics with poor-quality and conflicting evidence were eliminated. Several recommendations were combined. The quality of supporting evidence was variable. Seventeen final recommendations are included in the proposed guideline. DISCUSSION: We have developed a comprehensive, evidence-based ERAS guideline for neonates undergoing intestinal resection surgery. This guideline, and its creation process, provides a foundation for future ERAS guideline development and can ultimately lead to improved perioperative care across a variety of pediatric surgical specialties.

BACKGROUND: There are limited published data on pancreatic trauma imaging in children. OBJECTIVE: To present our experience using computed tomography (CT) and magnetic resonance (MR) imaging of pancreatic trauma in children and to correlate the imaging grade of pancreatic injury with management and outcome. MATERIALS AND METHODS: A retrospective cohort study of children with pancreatic injury presenting between Jan. 1, 2000, and Dec. 31, 2016, was performed. Patient charts were reviewed to note demographics, the mechanism of injury, associated abdominal injuries, management and outcome. All imaging was rereviewed by two radiologists blinded to clinical and laboratory information, and pancreatic injuries were graded according to the American Association for the Surgery of Trauma (AAST). RESULTS: Of 3,265 patients presented as trauma team activations during the study period, only 28 (0.86%) children (19 boys, 9 girls; mean age: 7.14 years; age range: 1-15 years) had pancreatic injury. Of the available 27 CTs of the abdomen, 26 were performed on the day of trauma. Associated injuries were seen in 25/27 children, most frequently in the liver and lung, 16 (59.2%) each. There were 5 (19%) Grade I, 9 (33%) Grade II, 8 (30%) Grade III and 3 (11%) Grade IV. No patients had Grade V injury. No pancreatic parenchymal injury was identified in 2 (7%) patients with isolated fluid around the pancreas and mesentery. The pancreatic duct was visible in all 10 children (days: 0-330, median days: 41 post-trauma) who had MRI. Eight of these children, who had Grade III/IV injuries on CT and confirmed pancreatic duct injury on endoscopic retrograde cholangiopancreatography (ERCP) or surgery, showed either signal intensity difference in pancreatic parenchyma and/or caliber difference in the pancreatic duct proximal and distal to the injury site. Two patients died because of multiorgan injuries, 9 patients (mainly with Grade III and IV injuries) underwent surgery and/or ERCP, and 16 patients were managed conservatively. AAST grading of pancreatic injury on CT correlated with type of management (P=0.0001) with most of the Grade III and IV injuries treated with intervention and/or surgery while all of the Grade I and II injuries were treated conservatively. CONCLUSION: Pancreatic injury is rare in children but often associated with other organ injuries most frequently involving the liver and lung. CT grading of injury correlates with management and guides intervention and/or surgery versus conservative treatment. MRI is useful for assessing pancreatic duct injury by demonstrating the pancreatic duct directly and/or secondary changes like signal intensity difference in pancreatic parenchyma and caliber difference in the pancreatic duct.
