Vitamin deficiencies in pediatric eosinophilic esophagitis: A systematic review.

BACKGROUND: Nutritional deficiencies are seen in patients with food allergy. Low vitamin D levels have been found in patients with atopic conditions. Eosinophilic esophagitis (EoE) is a chronic immune antigen-mediated disease found to be highly associated in patients with atopic disease and treated with dietary elimination with recommendations to utilize a dietician to prevent nutritional deficiencies. Nonetheless, the relationship between EoE and vitamin deficiency remains unclear. We aimed to systematically review the evidence to support a possible association between vitamin deficiency and eosinophilic esophagitis. METHODS: Electronic searches were performed with keywords relating to EoE and vitamins among pediatric patients in MEDLINE, EMBASE, and The Cochrane Library. Summary estimates were calculated. Citations were reviewed against pre-defined criteria. (Inclusion: human subjects, aged 0-18, with eosinophilic esophagitis. Exclusion: adults over 18 years, non-English papers). RESULTS: The search yielded 1707 studies. Five of these studies with a total of 137 pediatric patients were included in the systematic review. Outcome measures were assessed at different points in EoE treatment across studies. The single common outcome measure across all included studies was vitamin D. Reported prevalence of low vitamin D varied in these studies (0%-52%). Vitamin D levels of children with EoE both pre- and post-intervention were low. CONCLUSIONS: There is limited published literature on vitamin deficiencies associated with EoE both pre- and post-intervention. The limited data on vitamin D suggest that insufficiency or deficiency may be present in these patients, but it remains unclear whether deficiency is caused by diet. More prospective, well-defined studies, in addition to routine reporting on dietary intake and nutritional status, are needed to make any conclusions or recommendations for screening.

Impact of COVID-19 on Pediatric Gastroenterology Fellow Training in North America.

BACKGROUND: The COVID-19 pandemic has drastically changed healthcare systems and training around the world. The Training Committee of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition sought to understand how COVID-19 has affected pediatric gastroenterology fellowship training. METHODS: A 21 question survey was distributed to all 77 pediatric gastroenterology fellowship program directors (PDs) in the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition program director database via email on April 7. Responses collected through April 19, 2020 were analyzed using descriptive statistics. RESULTS: Fifty-one of 77 (66%) PDs from the United States, Canada, and Mexico responded to the survey. Forty-six of 51 (90%) PDs reported that they were under a "stay-at-home" order for a median of 4 weeks at the time of the survey. Two of the 51 (4%) programs had fellows participating in outpatient telehealth before COVID-19 and 39 of 51 (76%) at the time of the survey. Fellows stopped participating in outpatient clinics in 22 of 51 (43%) programs and endoscopy in 26 of 51 (52%) programs. Changes to inpatient care included reduced fellow staffing, limiting who entered patient rooms, and rounding remotely. Fellows in 3 New York programs were deployed to adult medicine units. Didactics were moved to virtual conferences in 47 of 51 (94%) programs, and fellows used various online resources. Clinical research and, disproportionately, bench research were restricted. CONCLUSIONS: This report provides early information of the impact of COVID-19 on pediatric fellowship training. Rapid adoption of telehealth and reduced clinical and research experiences were important changes. Survey information may spur communication and innovation to help educators adapt.

Pediatric Gastroenterology, Hepatology, and Nutrition Entrustable Professional Activities: Development of an Assessment Tool and Curricular Resources.

BACKGROUND: Entrustable professional activities (EPAs) are critical activities performed by medical professionals, which can be observed and assessed. Adding on to common EPAs for all pediatric subspecialty trainees, specialty-specific EPAs for pediatric gastroenterology, hepatology, and nutritional fellowship were developed by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) EPA Task Force. METHODS: Having developed specialty-specific EPAs, building EPA assessments is the next logical step, as EPAs are included under a larger umbrella of competency-based assessment. Thus, the NASPGHAN EPA Task Force and Training Committee collaborated on an assessment tool and associated curricular resources to aid in tracking trainees' progression to entrustment within individual EPAs and readiness for independent practice. RESULTS: This manuscript reports the development of an EPA assessment tool, including guiding principles and the theory behind the assessment tool, with a focus on simple, meaningful assessments that can provide crucial performance feedback to trainees. In addition, curricular resources were developed, based on the assessment tool, to support training. Ultimately, it is the hope of the NASPGHAN EPA Task Force and Training Committee that this tool can aid training programs in providing formative feedback for trainees, and can be used by training programs and clinical competency committees for summative evaluation.

Correlation Between Aeroallergen Levels and New Diagnosis of Eosinophilic Esophagitis in New York City.

OBJECTIVE: The relation between food allergies and eosinophilic esophagitis (EoE) is well established. Aeroallergens may also contribute to the development of EoE; however, there are limited data to support or refute this hypothesis. The objectives of this pilot study were to determine whether there is a seasonal variation in the onset of symptoms and/or diagnosis of EoE and whether these variations correlate with a specific pollen concentration within New York City. METHODS: We performed a retrospective chart review to identify all pediatric patients at New York Presbyterian Weill Cornell Medical Center diagnosed with EoE between 2002 and 2012. Sixty-six patients were identified and 28 were excluded. Cases were classified by both date of initial symptoms and date of histologic diagnosis. Pollen counts from a certified New York City counting station and the percentage of EoE cases were collated monthly and seasonally and compared. RESULTS: There was a seasonal variation in onset of symptoms and diagnosis of EoE, with the highest number of patients reporting onset of symptoms of EoE in July to September, and those being diagnosed with EoE in October to December. There was a seasonal correlation between peak levels of grass pollen and peak onset of EoE symptoms, which were both highest in July to September. The diagnosis of EoE peaked one season later. CONCLUSIONS: The study findings suggest that there is a correlation between specific aeroallergens and both the onset of symptoms and time of diagnosis of patients with EoE.

Using the Objective Structured Clinical Examination to Assess ACGME Competencies in Pediatric Gastroenterology Fellows.

BACKGROUND: The Accreditation Council for Graduate Medical Education has described 6 core competencies with which trainees should demonstrate proficiency. Using the Objective Structured Clinical Examination (OSCE), we aimed to assess 4 of these competencies among Pediatric Gastrointestinal (GI) fellows (PGs). METHODS: Eight first-year PGs from 6 medical centers in the New York area participated in a 4-station OSCE with trained standardized patient (SP) actors. The cases included an emergency department (ED) consult, or "ED Consult" for lower gastrointestinal bleeding; "Breaking Bad News" focusing on CF nutritional complications; "Second Opinion" for abdominal pain; "Transition of Care" for inflammatory bowel disease. At each station, attending faculty observed the encounters behind a 1-way mirror. SPs and faculties provided immediate feedback to the examined fellows. Previously validated OSCE checklists were used to assess performance. On completion, fellows attended debriefing sessions and completed surveys about the educational value. RESULTS: Median overall milestone competency scores were 6.9 (PC1), 4.8 (PC2), 5.9 (MK1), 5.7 (MK2), 6.4 (ICS1), 6.9 (Prof1), and 6.7 (Prof3). Overall, fellows score highest (7/9) on the inflammatory bowel disease "Transition of Care" case, found the "Breaking Bad News" Cystic Fibrosis OSCE to be the most challenging, and were most comfortable with the "ED Consult" OSCE, as a commonly encountered scenario. Overall, the fellows rated the educational value of the program highly. CONCLUSIONS: To our knowledge, although the OSCE has been validated in other medical fields, this is the first OSCE program developed for PGs fellows. These OSCEs have included Accreditation Council for Graduate Medical Education competencies, serving to assess fellows' skills in these areas while exposing them to challenging medical and psychosocial cases that they may not frequently encounter.

Longitudinal diffusion-weighted imaging changes in children with small bowel Crohn's disease: preliminary experience.

PURPOSE: Crohn's disease has been associated with restricted diffusion in diseased small bowel segments on diffusion-weighted imaging (DWI). However, data addressing longitudinal changes in DWI findings and their potential clinical ramifications in the pediatric population are lacking. The purpose of this study was to follow DWI changes in diseased small bowel segments between serial magnetic resonance enterography (MRE) examinations, and to correlate these changes with other imaging parameters and clinical status. METHODS: This retrospective study evaluated patients less than 21 years of age undergoing serial MRE examinations including DWI for Crohn's disease involving the small bowel. All patients carried a diagnosis of Crohn's disease established by pathology or corroborative clinical and imaging findings. Longitudinal changes in mean apparent diffusion coefficient (ADC) values within the wall of affected small bowel lesions were recorded and normalized to both unaffected bowel and skeletal muscle. ADC changes were correlated with qualitative imaging phenotype, as reflected by a defined set of non-DWI imaging parameters, as well as with clinical disease activity. RESULTS: Seventeen lesions were evaluated longitudinally, distributed among 13 patients (9 boys and 4 girls, mean age at baseline 16.6 years), each of whom had two sequential MRE examinations. Lesions demonstrating a fibrostenotic imaging phenotype at follow-up MRE had a significantly lower change in mean ADC value between examinations than lesions that did not have a fibrostenotic imaging phenotype (p = 0.0005), an effect that persisted when ADC values were normalized to unaffected bowel and skeletal muscle. Across all studies, lesions with a fibrostenotic imaging phenotype had lower ADC values than those with an inflammatory imaging phenotype, which were in turn lower than those with a normal imaging phenotype (p = 0.0001). CONCLUSION: Patterns of longitudinal DWI changes in Crohn's disease may differ among small bowel lesions depending upon their specific natural histories. These findings may assist in the evaluation of the ADC value as a potential imaging surrogate when evaluating lesion status, particularly as it pertains to relative contributions of inflammation and fibrosis.

Delivering bad or difficult news. An innovative simulation-based education approach to prepare interdisciplinary fellowships.

BACKGROUND: There is limited data on the effectiveness of training interventions to improve the delivery of bad news. METHODS: This preliminary research included pre-post assessments and an open-ended survey to evaluate the effectiveness and perceived value of training on delivering bad news for 26 first- and second-year fellows from five adult and pediatric fellowship programs. RESULTS: There was a significant increase in faculty assessment scores (34.5 vs. 41.0, respectively, Z = -3.661, p < 0.001) and Standardized Patient (SP) assessment scores (37.5 vs .44.5, respectively, Z = -2.244, p = 0.025). Fellows valued having a standard framework to aid in the delivery of bad news; receiving targeted feedback and having the opportunity to apply their skills in a subsequent case. CONCLUSIONS: A one-hour, four-phase lesson plan that includes an individualized training approach and simulation do-overs can be effective and valuable for preparing fellows to deliver bad news.

Efficacy and Outcomes of Faecal Microbiota Transplantation for Recurrent Clostridioides difficile Infection in Children with Inflammatory Bowel Disease.

BACKGROUND: Children with inflammatory bowel disease [IBD] are disproportionally affected by recurrent Clostridioides difficile infection [rCDI]. Although faecal microbiota transplantation [FMT] has been used with good efficacy in adults with IBD, little is known about outcomes associated with FMT in paediatric IBD. METHODS: We performed a retrospective review of FMT at 20 paediatric centres in the USA from March 2012 to March 2020. Children with and without IBD were compared with determined differences in the efficacy of FMT for rCDI. In addition, children with IBD with and without a successful outcome were compared with determined predictors of success. Safety data and IBD-specific outcomes were obtained. RESULTS: A total of 396 paediatric patients, including 148 with IBD, were included. Children with IBD were no less likely to have a successful first FMT then the non-IBD affected cohort [76% vs 81%, p = 0.17]. Among children with IBD, patients were more likely to have a successful FMT if they received FMT with fresh stool [p = 0.03], were without diarrhoea prior to FMT [p = 0.03], or had a shorter time from rCDI diagnosis until FMT [p = 0.04]. Children with a failed FMT were more likely to have clinically active IBD post-FMT [p = 0.002] and 19 [13%] patients had an IBD-related hospitalisation in the 3-month follow-up. CONCLUSIONS: Based on the findings from this large US multicentre cohort, the efficacy of FMT for the treatment of rCDI did not differ in children with IBD. Failed FMT among children with IBD was possibly related to the presence of clinically active IBD.
