RESUMEN
OBJECTIVE: In functional dyspepsia patients, duodenal mucosal eosinophilia has been associated with early satiety but is not present in all patients suggesting varied pathways to symptom generation. The objective of the current study was to explore metabolic differences comparing those with duodenal mucosal eosinophilia to those without eosinophilia. METHODS: This study was conducted utilizing an existing biorepository. Patients had plasma samples obtained at the time of endoscopy. All had undergone endoscopy for dyspepsia and reported early satiety. Two groups were identified including those with peak duodenal mucosal eosinophil densities above 30/high power field (N = 28) and those below 30 (N = 16). The fasting plasma samples were analyzed by liquid chromatography/high-resolution mass spectrometry. Significant differences between groups were determined. RESULTS: The eosinophilia group demonstrated significant elevations in several gamma-glutamyl amino acids. The eosinophilia group had elevations of metabolites associated with oxidative stress including glutathione metabolites (cysteinlyglycine and cys-gly oxidized), and metabolites related to nitric oxide synthesis (arginine, citrulline, ornithine, and dimethylarginine). Eosinophilia was also associated with alterations in lipid metabolism including several long-chain acylcarnitine conjugated fatty acids. Carnitine levels were lower in the eosinophilia group. Lastly, vanillymandelate, a derivative of norepinephrine and epinephrine was elevated in the eosinophilia group. CONCLUSIONS: In patients with dyspepsia and early satiety, duodenal mucosal eosinophilia is associated with metabolites levels which are consistent with increased oxidative stress and alterations in lipid metabolism. Eosinophilia was also associated with lower carnitine levels. These alterations may contribute to pathophysiology and represent therapeutic targets.
RESUMEN
HIGHLIGHTS: Patient comfort during peripheral intravenous (PIV) insertion and specimen collection was increased. The authors extended the contingency plan implemented for PICC insertion to include PIV insertion and specimen collection. The authors met their goals by using quality improvement methodology. Prioritizing patient comfort often requires institutional culture change. BACKGROUND: Needle procedures can cause pain and distress, especially in pediatric patients.1 Retrospective data collected at a freestanding pediatric facility revealed that approximately 30% of pediatric patients were not demonstrating sufficient levels of comfort during peripheral intravenous (PIV) catheter insertion and specimen collection (lab draws) even after successful implementation of comfort measures by the vascular access team (VAT) in an adjacent procedure (eg peripherally inserted central catheter placement). The current quality improvement project was implemented to support adaptation and expansion of previous lessons learned to PIVs and lab draws specifically. DESIGN AND METHODS: The VAT used the Pediatric Sedation State Scale,2 a standardized assessment tool integrated into the electronic medical record, to assess procedural comfort during PIVs and lab draws from February 2021 through April 2023. A total of 24 134 patients aged 0 to 18 years were included in the data collection. Interventions were delivered concurrently and included (1) reeducation/ongoing support for implementation of the Comfort Promise3 measures, (2) the creation and implementation of advanced comfort options, and (3) culture change. AIMS AND OBJECTIVES: The goal of the interventions was to improve the percentage of pediatric patients achieving adequate levels of comfort beginning at 68% in year 1 to 90% in year 2. RESULTS: From February 2021 to April 2023, the VAT team was able to improve procedural comfort scores from 68% to 90% of pediatric patients with adequate comfort for lab draws and/or PIV insertions. CONCLUSIONS: While standard comfort measures are a good first step in pain management during needle procedures, they are not sufficient for every pediatric patient. Nitrous, sedation, and the use of anxiolytics and analgesics can play an important role in reducing pain and anxiety during needle procedures and should be considered for patients not achieving adequate levels of comfort with standard comfort measures.

INTRODUCTION: Many evidence-based tools exist to address pain and distress associated with injections; however, there remains a large gap between the knowledge of these tools and their utilization. Our hospital began a quality improvement (QI) project prior to COVID-19, with the goal of increasing the utilization of Comfort Promise measures during needle procedures. When COVID-19 vaccinations were approved, our mass vaccination clinics provided an opportunity to rapidly increase utilization across the institution. The primary aim was to increase the percentage of comfort measures (CM) offered with COVID-19 vaccinations. METHODS: Through this QI project, nurses and other professionals implemented CMs during COVID mass vaccination clinics. Clinics occurred in 3 age-based waves. Waves served as Plan-Do-Study-Act (PDSA) cycles. Families completed post-vaccination surveys to determine what CMs were offered and intention for future use with vaccinations. RESULTS: Uptake of CMs (PainEase, ShotBlockers, Comfort Positioning, Alternative Focus, Topical Lidocaine, and Breastfeeding/Sucrose) throughout the waves increased and generally remained stable. CMs also seemed to decrease pain/distress with vaccinations (70.5 to 88.7%), and children/caregivers intended to use some combination for future vaccinations (82.5 to 98.5%). CONCLUSIONS: Fast-paced mass vaccination clinics provided an ideal opportunity to significantly increase utilization of CMs. Across age groups CMs yielded high satisfaction and interest in future utilization. Clinic nurses returned to their own sub-specialties and became change agents. IMPLICATIONS: If all healthcare providers can work together to achieve consensus while incorporating comfort measures into daily practice, sustained change with incorporation of these evidence-based tools can be achieved. Future directions are discussed.

The aims of the current study were to determine the frequencies of specific sleep disturbances in youth with abdominal pain-associated disorders of gut-brain interaction (AP-DGBIs) and to assess relationships with psychological dysfunction. This was a retrospective evaluation of 226 consecutive patients diagnosed with an AP-DGBI. All had undergone a systematic evaluation of gastrointestinal symptoms, the Sleep Disturbance Scale for Children, and the Behavior Assessment System for Children. Disorders of initiation and maintenance of sleep (DIMS; 40%) and disorders of excessive daytime somnolence (DOES; 14%) were each present in more than 10% of the patients. Both DIMS and DOES scores were more likely to be elevated in patients with anxiety and/or depression scores in the at-risk or elevated-risk ranges. Sleep disorders are common in youth with AP-DGBIs and are associated with anxiety and depression, even in those patients with anxiety and depression in the at-risk range.
RESUMEN
The purpose of the current study was to assess the frequency of overactive bladder syndrome (OBS) symptoms and their relationship to gastrointestinal symptoms in youth with abdominal pain-associated disorders of gut-brain interaction (AP-DGBI). This is a retrospective study of 226 youth diagnosed with an AP-DGBI. As part of standard care, all patients completed a symptom questionnaire regarding gastrointestinal and non-gastrointestinal symptoms including increased urinary frequency, nighttime urination, and urinary urgency. Overall, 54% of patients reported at least one OBS symptom. Increased frequency of urination was reported by 19%, urinary urgency by 34%, and nighttime urination by 36%. Increased frequency of urination and urinary urgency were associated with a change in stool form, a change in stool frequency, and in those fulfilling criteria for IBS. Increased frequency of urination was reported more frequently in those reporting predominantly loose stools (33% vs. 12%). Urinary symptoms are common in youth with AP-DGBI. Increased urinary frequency and urinary urgency are specifically associated with IBS, with increased urinary frequency being primarily associated with diarrhea predominant IBS. Further studies are needed to determine the impact of OBS on AP-DGBI severity and quality of life, and whether they impact DGBI treatment.

OBJECTIVES: Current literature in pediatric pain evaluates the Fear Avoidance model (FAM) pathways at the trait (or macrotemporal) level, but it is unknown if these pathways also occur at the state (or microtemporal) level. Identifying microtemporal processes can improve our understanding of how the relationships within the Fear Avoidance constructs vary when specific Fear Avoidance variables wax and wane. We hypothesized that changes in FAM constructs would be associated with changes in the next variable in the sequence on a microtemporal level, including: (1) higher pain when there is more pain-related fear, (2) higher pain-related fear when there is more avoidance, and (3) higher avoidance when there is more reported disability. METHODS: 71 pediatric patients with chronic abdominal pain ( M =13.34 y, SD=2.67 y) reported pain severity, pain-related fear, and avoidance via ecological momentary assessments over 14 days. RESULTS: Our results indicated significant microtemporal relationships between Fear Avoidance constructs for pain predicting pain-related fear, pain-related fear predicting avoidance, and avoidance predicting disability. DISCUSSION: The current study suggests that the ways in which the FAM is related to various aspects of pain functioning differs on a state-level, which adds new clinical and research opportunities.

BACKGROUND: Pediatric Rome IV criteria are used to diagnose childhood functional gastrointestinal disorders (FGIDs). This study of pediatric gastroenterology physicians measured their agreement in (1) Making a pediatric Rome IV FGID diagnosis; and (2) Diagnostic testing for patients with FGIDs. METHODS: Pediatric gastroenterologists and pediatric gastroenterology fellows at two medical centers completed a survey containing clinical FGID vignettes. For each vignette, raters identified the most likely Rome IV diagnosis(es) and selected which diagnostic test(s) (if any) they typically would obtain. The survey was re-administered within 3 months. Inter-rater and intra-rater weighted percent agreement was determined. Linear mixed modeling identified sources of variability in diagnostic testing. KEY RESULTS: Thirty-four raters completed the initial survey of whom thirty-one (91%) completed the repeat survey. Overall inter-rater agreement on Rome IV diagnoses was 68% for initial and repeat surveys whereas intra-rater agreement was 76%. In contrast, overall inter-rater agreement on diagnostic testing was <30% for both initial and repeat surveys and intra-rater agreement was only 57%. Between-physician differences accounted for 43% of the variability in the number of tests selected. Rater identified use of Rome criteria in clinical practice was associated with 1.1 fewer diagnostic tests on average (95% CI 0.2-2.0, p = 0.015). Higher intra-rater agreement was noted for diagnostic testing in faculty when compared to fellows (p = 0.009). CONCLUSIONS & INFERENCES: In a multicenter evaluation among pediatric gastroenterology physicians, pediatric Rome IV diagnostic agreement was higher than that reported for previous Rome versions, and higher than agreement on diagnostic testing.

OBJECTIVES: The primary objective was to describe patterns of care delivery locations in youth with abdominal pain-associated functional gastrointestinal disorders (AP-FGID) and assess for differences in patterns of care delivery by sex and race. A secondary objective was to describe cost variability within the emergency department (ED). METHODS: Data were obtained using a large, single-vendor database that extracts and deidentifies data from the electronic health record across the outpatient, ED, and inpatient continuum of care. We evaluated patients 8 to 17 years of age seen over an 8-year period for a priority 1 diagnosis of an AP-FGID. Data collected included age, sex, race, encounter location, and total cost of ED encounters. We specifically assessed how often patients seen in the ED were also seen in outpatient or inpatient settings. RESULTS: A total of 53,750 patients (64% female; mean age, 13.3 ± 2.8 years) were identified and assessed. The most common location of care was the ED (48.8%) followed by the outpatient setting (46.2%). Of patients seen for a priority 1 AP-FGID diagnosis in the ED, only 3.7% were seen for a priority 1 diagnosis in the outpatient setting, and only 1% were seen in an inpatient setting. Overall, females received 42.5% of their care and males received 44.8% of their care in the ED. The overall rate of ED care was 66.9% for Hispanic, 61.5% for African American, 55.1% for Asian, 46.6% for Native American, and 36.9% for Caucasian patients. CONCLUSIONS: The ED is the most common location for care for youth with AP-FGIDs and, for the majority, seems to be the only location. This seems to be particularly true for Hispanic and African American patients. Given the often complex psychosocial needs of this patient group, processes need to be developed to transition these patients into the outpatient setting, ideally to programs specializing in chronic pain.

The purpose of this study was to assess cost variability in the care of abdominal pain-associated functional gastrointestinal disorders (AP-FGIDS) in youth across health systems, races, and specific AP-FGID diagnoses. Patients, aged 8-17 years, with a priority 1 diagnosis corresponding to a Rome IV defined AP-FGID were identified within the Health Facts® database. Total costs were obtained across the continuum of care including outpatient clinics, emergency department, and inpatient or observation units. Cost variability was described comparing different health systems, races, and diagnoses. Thirteen thousand two hundred and fourteen patients were identified accounting for 17,287 encounters. Total costs were available for 38.7% of the encounters. There was considerable variability in costs within and, especially, across health systems. Costs also varied across race, urban vs. rural site of care, and AP-FGID diagnoses. In conclusion, there was considerable variability in the costs for care of AP-FGIDs which is sufficient to support multi-site studies to understand the value of specific tests and treatments. Significant differences in costs by race merit further investigation to understand key drivers.
RESUMEN
Introduction: Rumination syndrome involves recurrent regurgitation of food and is believed to be underdiagnosed with patients experiencing long delays in diagnosis. It can be associated with significant social consequences, high rates of school absenteeism, and medical complications such as weight loss. The primary aims of the current review are to assess the literature regarding prevalence, pathophysiology, and treatment outcomes with a focus on neurotypical children and adolescents. Results: Population studies in children/adolescents, 5 years of age or older, range from 0 to 5.1%. There are fewer studies in clinical settings, but the prevalence appears to be higher in patients with other gastrointestinal symptoms, particularly chronic vomiting. While physiologic changes that occur during a rumination episode are well-described, the underlying cause is less well-defined. In general, rumination appears to have similarities to other functional gastrointestinal disorders including dysmotility, possibly inflammation, and an interaction with psychologic function. While diaphragmatic breathing is considered the mainstay of treatment, pediatric data demonstrating efficacy is lacking, especially as an isolated treatment. Conclusion: Pediatric rumination syndrome remains greatly understudied, particularly regarding treatment. There is a need to better define prevalence in both the primary care and subspecialty clinical settings, especially in patients presenting with vomiting or apparent gastroesophageal reflux. There is a need to determine whether treatment of co-morbid conditions results in improvement of rumination. Diaphragmatic breathing needs to be studied and compared to other competing responses.
RESUMEN
Chronic abdominal pain is very common in children and adolescent and results in high personal and social costs. Most youth with chronic abdominal pain fulfill criteria for a functional abdominal pain disorder (FAPD) as defined by Rome criteria. These are complex conditions with a wide array of biological, psychological, and social factors contributing to the experience of pain. The purpose of the current review is to provide an overview of the pathophysiology of FAPDs and an up-to-date summary of the literature related to FAPDs in children and adolescents, with additional focus on several areas (eg, diet and probiotics) where patients and families frequently have questions or implement self-directed care. We also provide an approach to the assessment and treatment of pediatric FAPDs focusing on the robust literature regarding psychological interventions and much sparser literature regarding medication treatment.
RESUMEN
BACKGROUND: Rumination syndrome has been associated with increased duodenal eosinophils and intraepithelial lymphocytes in adults. The aims of the current study were to assess densities of antroduodenal eosinophils and mast cells and duodenal intraepithelial lymphocytes in youth with rumination syndrome and to compare cell densities in those with and without abdominal pain or early satiety. METHODS: Twenty-eight youth fulfilling Rome IV criteria for rumination syndrome who had undergone endoscopy were identified and compared to 10 controls. Antral and duodenal biopsies were assessed to determine densities of eosinophils, mast cells, and intraepithelial lymphocytes. Cell densities were also compared between rumination patients with and without abdominal pain and those with and without early satiety. KEY RESULTS: Antral mast cell (peak 18.5±6.5 vs. 12.5±2.7) and eosinophil (peak 9.6±5.2 vs. 4.9±2.1) densities were significantly greater in patients with rumination syndrome as compared to controls. Duodenal intraepithelial lymphocyte densities were also increased in rumination syndrome (18.9 ± 5.1 vs. 11.7 ± 1.5; p<.001). Associations were independent of the presence of abdominal pain or early satiety. CONCLUSIONS AND INFERENCES: In conclusion, we found an increase in eosinophil and mast cell densities in the gastric antrum and an increase in intraepithelial lymphocytes in the duodenum in youth with rumination syndrome which was independent of the presence of abdominal pain or early satiety. These findings suggest a potential role for inflammation in the pathophysiology of rumination syndrome. Future studies should address whether treatment directed at these cells are beneficial in treating rumination syndrome.

ABSTRACT: The aim of this study was to assess the relationship of heartburn in pediatric patients with functional dyspepsia (FD) and irritable bowel syndrome (IBS) with gastrointestinal symptoms, sleep disturbances, and psychologic distress.The overlap in symptoms of FD, IBS, and gastroesophageal reflux disease (GERD) predicts greater symptom severity and decreased quality of life and presents opportunities for improved diagnostic classification and personalized therapeutics.A cross-sectional observational study of 260 pediatric patients with abdominal pain was conducted. Patients completed standardized questionnaires assessing clinical symptoms, sleep quality, and psychologic symptoms during routine clinical care. Questionnaire data were compared for patients reporting heartburn and not reporting heartburn using χ2 and t tests where appropriate.Gastrointestinal symptoms were significantly more prevalent among patients with a positive report of heartburn (vs a negative report of heartburn): pain with eating (83% vs 67%, Pâ=â.007), bloating (63% vs 44%, Pâ=â.005), acid regurgitation (47% vs 24%, Pâ≤â.001), and chest pain (45% vs 20%, Pâ≤â.001). Likewise, initiating and maintaining sleep (Pâ=â.007), arousal/nightmares (Pâ=â.046), sleep-wake transition (Pâ=â.001), hyperhidrosis during sleep (Pâ=â.016), and anxiety (Pâ=â.001) and depression (Pâ=â.0018) were also significantly increased in patients who reported heartburn versus patients who did not report heartburn.Patients with a positive report of heartburn, whether classified as having FD and/or IBS, had increased gastrointestinal symptoms, sleep disturbances, anxiety, and depression than patients with a negative report of heartburn. A better understanding of these associations may allow for personalized treatment for youth with abdominal pain and heartburn as a primary symptom.

BACKGROUND/PURPOSE: Most studies examining the components of the fear-avoidance model have examined processes at the group level. The current study used ecological momentary assessments to: (a) investigate the group and intraindividual relationships between pain fear, avoidance, and pain severity, (b) identify any heterogeneity between these relationships, and (c) explore the role of moderators to explain such heterogeneity. METHODS: Seventy-one pediatric patients with chronic abdominal pain (M = 13.34 years, standard deviation = 2.67 years) reported pain fear, avoidance, and pain severity four times per day over 14 days. RESULTS: Results indicated significant individual differences in the relationship between pain fear and pain avoidance predicting pain severity. Child age helped explain the heterogeneity in the relationships between pain avoidance and pain severity such that older children had a stronger and more positive relationship between these variables. The random effect between pain fear and pain severity also indicated a moderator trend of child age such that older children were likely to have a stronger and more positive relationship. CONCLUSIONS: The present study extends the fear-avoidance model by highlighting the importance of identifying potential individual differences when examining pain fear, avoidance, and pain severity. Furthermore, the current study suggests that child development should be considered in the model. However, future randomized control designs are necessary to explore the causal relationships between pain fear and avoidance on pain severity and potential developmental differences.

Elective surgical and endoscopic procedures were suspended nationwide during the March 2020 COVID-19 pandemic to minimize exposure and healthcare resource utilization. This resulted in an unprecedented backlog of procedures in most clinical practices including pediatrics. Our group developed an internal process toward the rational development of an algorithm prioritizing elective procedures. This was based on patient disease severity defined by the presence of alert symptoms, symptom severity for dysphagia and abdominal pain, and diagnostic investigation findings. The underlying rationale is to prioritize patients in whom suspected disease course would be greatest impacted by endoscopy. We developed a nurse phone call-based process utilizing REDCap®, identifying relevant symptoms categorized by severity, and a validated functional impairment questionnaire for abdominal pain. We abstracted key laboratory and radiological findings also categorized by severity. The order of priority of procedures was established on the basis of a 4-tiered system factoring both presence and severity of symptoms or prior diagnostic testing results. We present the framework that we have adopted toward prioritizing procedures with the assumption that it offers an objective methodology and that can be efficiently and more broadly applied to other similar practice scenarios. Our tool may have wide-ranging implications both in the current COVID-19 pandemic and in other scenarios of limited resource allocation and deserves further investigation.

Both mucosal inflammation and psychologic dysfunction have been implicated in irritable bowel syndrome (IBS). While some relationships between inflammation (mast cells and eosinophils) and depression have been reported in adults with IBS, relationships between inflammation and psychologic function have not been studied in children and adolescents. The aims of the current study were to: (1) assess densities of colonic mast cells, eosinophils, and TH17 cells in youth with IBS; and, (2) explore relationships between these cells and specific IBS symptoms and psychologic functioning. Utilizing previously obtained biopsies from the descending and rectosigmoid colons, densities were determined for mast cells, eosinophils, and TH17 cells, respectively, in 37 youth with IBS and 10 controls. In IBS patients, densities were assessed in relation to specific IBS symptoms and in relation to self-report anxiety and depression scores. In both the descending and rectosigmoid colons, densities of mast cells, eosinophils, and TH17 cells were higher in IBS patients as compared to controls. In IBS patients, rectosigmoid mast cell density was higher in those reporting pain relief with defecation. Also, in IBS patients, rectosigmoid eosinophilia was associated with higher anxiety scores and eosinophil density correlated with depression scores. In the descending colon, eosinophil and mast cell densities both correlated with depression scores. In conclusion, mucosal inflammation (mast cells and eosinophils) is associated with pain relief with defecation and with anxiety and depression in youth with IBS.

BACKGROUND: Nausea is a common symptom in youth with chronic abdominal pain. The aims of the current study were to assess: 1) the frequency of nausea in patients with functional dyspepsia (FD) and irritable bowel syndrome (IBS), respectively, as defined by Rome IV criteria; and, 2) relationships between nausea and mucosal inflammation as defined by antral and duodenal eosinophil and mast cell densities. A secondary aim was to assess relationships between nausea and other gastrointestinal symptoms, non-gastrointestinal somatic symptoms, and psychological dysfunction. METHODS: Records from patients with pain associated functional gastrointestinal disorders were retrospectively reviewed for gastrointestinal and somatic symptoms and anxiety, depression, and somatizations scores as assessed by the Behavior Assessment System for Children (BASC-2). In addition, previous gastric and mucosal biopsies were assessed for mast cell and eosinophil densities, respectively. RESULTS: 250 patients, ages 8 to 17 years, were assessed. Nausea was reported by 78% and was equally prevalent in those with FD alone, those with IBS alone, and those with both FD and IBS. Nausea was associated with increased mean (21.4 vs. 17.5) and peak (26.2 vs. 22.9) duodenal mast cell densities as compared those without nausea. Nausea was also associated with a wide variety of individual gastrointestinal symptoms, as well as headaches, fatigue, and dizziness. Lastly, nausea was associated with elevated self-report scores for anxiety (55.2 vs. 50.0), depression (50.2 vs. 46.1), and somatization (70.3 vs. 61.8). CONCLUSIONS: Nausea is common in children and adolescents with pain-associated FGIDs as defined by Rome IV and is not unique to either FD or IBS. Nausea is associated with increased mucosal mast cell density, non-gastrointestinal somatic symptoms, and psychologic dysfunction.

Introduction: While functional gallbladder disorder is a well-recognized and defined condition in adults, its pediatric analog, biliary dyskinesia, lacks uniformity in diagnosis. Yet, biliary dyskinesia is among the most common conditions resulting in cholecystectomy in youth and its frequency continues to rise. The primary aims of the current review were assess the efficacy of cholecystectomy in children diagnosed with biliary dyskinesia and the utility of cholescintigraphy in predicting outcomes. Results: All previous studies assessing outcomes in youth with biliary dyskinesia have been retrospective and therefore of low quality. There is a lack of uniformity in patient selection. Short term follow-up reveals partial response in 63.4-100% with complete resolution in 44.2-100%. Only 4 studies have reported long-term outcomes with complete symptom resolution in 44-60.7%. The published research generally indicates that the gallbladder ejection fraction (GBEF) as determined by cholescintigraphy lacks utility in predicting cholecystectomy outcome utilizing the commonly used cut-off values. There are data suggesting that more extreme cut-off values may improve the predictive value of GBEF. Conclusion: There is a lack of consensus on the symptom profile defining biliary dyskinesia in youth and current literature does not support the use of cholescintigraphy to select patients for cholecystectomy. There is a substantial portion of pediatric patients diagnosed with biliary dyskinesia who do not experience long-term benefit from cholecystectomy. Well-designed prospective studies of surgical outcomes are lacking. Increasing the uniformity in patient selection, including both symptom profiles and cholescintigraphy results, will be key in understanding the utility of cholecystectomy for this condition.
RESUMEN
BACKGROUND: Meal-related symptoms are common in paediatric functional dyspepsia (FD). There are only a small number of paediatric studies assessing mechanisms for meal-related symptoms, and these have not utilized Rome IV criteria. The aim of the current study was to assess gastric myoelectric and autonomic nervous system (ANS) responses to both liquid and solid meals in youth with Rome IV-defined FD. METHODS: In healthy controls (N = 14) and youth with FD (N = 12), we recorded electrocardiograph (to assess heart rate variability; HRV) and electrogastrograph (EGG) signals before and after two test meals, one liquid and one solid. EGG parameters and HRV were assessed for the entire pre- and postprandial periods and in short time intervals. Additionally, liquid gastric emptying was assessed utilizing a 13 C-acetate breath test. KEY RESULTS: During the EGG, the dominant power increased with both meals in controls but not patients with FD. During HRV assessment, the low frequency to high frequency ratio was higher after the liquid meal in controls, despite being similar preprandial, as compared to patients with FD. In controls, both standard deviation of normal to normal waves (SDNN) and root mean square of successive ECG R peaks (R-R interval) differences (rMSSD) increased after the liquid meal (but not after the solid meal) in controls but not patients with FD. CONCLUSIONS AND INFERENCES: Youth with Rome IV-defined FD lacks the normal postprandial EGG dominant power response or autonomic nervous system response following a liquid meal. The latter appears to indicate a lack of ANS flexibility.
