Objectives: Human milk intake has many benefits which could influence outcomes in biliary atresia (BA). However, the role of human milk in BA has not been examined. We hypothesized that human milk intake would be associated with improved outcomes in BA.

Methods: We assessed the impact of any human milk (AHM) as compared to formula only (FO) intake before Kasai portoenterostomy (KP) on outcomes in 447 infants with BA using the PROBE database (NCT00061828) post hoc. The primary outcome was clearance of jaundice (COJ = total bilirubin (TB) < 2 mg/dL by 3 months post-KP). Secondary outcomes included 2-year native liver survival (SNL), bilirubin levels, cholangitis, ascites, and growth. We assessed the fecal microbiome (n = 8) comparing AHM versus FO.

Results: At baseline, 211 infants received AHM and 215 received FO. 53.9% of AHM and 50.5% of FO achieved COJ (p = NS). SNL was insignificantly increased in AHM (odds ratio = 1.47, 95% confidence interval: 1.00-2.12, p = 0.053). TB decreased in AHM from 4 weeks to 3 months post-KP [4.8-4.0 mg/dL (p = 0.01)] unlike the FO group (4.9-4.9 mg/dL, p = 0.4). At 3 months post-KP, AHM infants had greater weight gain (1.88 ± 0.66 vs. 1.57 ± 0.73 kg, p < 0.001) and mid-upper arm circumference (12.9 ± 1.4 vs. 12.2 ± 1.7 cm, p < 0.001). Other secondary outcomes were not different. Microbiome differences were seen between AHM and FO.

Conclusions: Human milk intake in infants with BA did not significantly improve COJ or SNL. However, growth parameters were improved, and TB 3 months post-KP was decreased. Thus, human milk intake should not be discouraged. Prospective studies with detailed assessment of human milk intake are needed.

Objective: Breast milk (BM) enhancement is often used to meet the nutritional needs of preterm infants after hospital discharge to achieve optimal growth. This study compared growth at 18-28 months corrected age (CA) among very preterm (VP) and very low birth weight (VLBW) infants discharged from the neonatal intensive care units (NICUs) on two BM enhancements.

Methods: We conducted a retrospective chart review study of infants born between January 1, 2013 and December 31, 2017, with gestational age < 32 weeks or birthweight < 1500 g, discharged from the NICU on BM enhancements; fortification of BM with infant formula additives (BM-F) or unfortified BM supplemented with bottle feeds of infant formula (BM-S). BM enhancements were nonrandomized and determined by the medical team. A linear mixed model regression analysis with propensity score matching was used to estimate the adjusted associations between the nutrition plan at discharge and growth outcomes at 18-28 months CA follow-up.

Results: Two hundred and fifty-one VLBW/VP infants were included. Compared with BM-S, infants discharged on BM-F were more likely to continue receiving BM at 8-12 months CA, and had lower head circumference, weight-for-length z scores, and higher incidence of moderate malnutrition (p ≤ 0.01). After adjusting for confounders, discharge on BM-F was associated with a lower incidence of overweight/obesity at 18-28 months CA (odds interval: 0.45; confidence interval: 0.21-0.96; p = 0.04).

Conclusions: This retrospective study suggests that VLBW/VP infants discharged on BM-F received BM longer, had lower growth parameter and were less likely to be overweight/obese at 18-28 months CA. Further studies are needed to evaluate the role of postdischarge nutrition on preterm born children's growth, metabolic disease, and neurodevelopmental outcomes.

Objective: Glycogen storage disorders (GSD), inherent disorders of carbohydrate metabolism, feature hypoglycemia as a hallmark. Normoglycemia and glucose monitoring are pivotal in disease management. Conventional glucometer-based monitoring may overlook hypoglycemic trends. This study assesses glycemic control in Asian Indian GSD children using continuous glucose monitoring (CGM) and its role in facilitating dietary adjustments.

Methods: A pre-post study enrolled molecularly confirmed GSDI, GSDIII, GSDVI, and GSDIX patients for baseline dietary compliance and CGM-based glycemic status evaluation. Hypoglycemic patients were stratified into diet-compliant and diet-noncompliant groups. Noncompliant patients received dietary reinforcement; compliant individuals underwent dietary adjustments. Repeat CGM (rCGM) was performed 6 weeks to 6 months postadjustments. Clinical and metabolic parameters were re-evaluated at 6 months.

Results: Of the 20 patients assessed at baseline, 11 were diet compliant. Six among these exhibited hypoglycemia, prompting diet adjustments. Among nine noncompliant patients, eight experienced hypoglycemia and received diet reinforcement. rCGM in 10 patients (five GSDI, three GSDIII, and two GSDIXc) showed a significant reduction in hypoglycemia duration in all. An improvement in height and body mass index was observed in all GSDI and GSDIII patients. Triglyceride levels, raised at baseline in two GSDI and one GSDIII, showed a substantial decline in one GSDI patient. Hepatic transaminase levels decreased in both GSDIXc patients. Plasma lactate levels decreased in all GSDI patients.

Conclusion: CGM is an efficacious adjunct in the personalized management of hepatic GSD patients, in the Asian Indian population. The study also underscores the need for long-term follow-up to determine the role of glycemic management in growth, general well-being, and metabolic control in the GSD subtypes.

Objectives: The fatty acid (FA) supply of human milk (HM) contributes to health outcomes. Sampling fresh HM to analyze its FA content is challenging because of its ever-changing nature. Also, obtaining samples from lactating mothers is challenging. Facilitating HM collection and analysis is therefore an advantage.

Methods: We have conducted a study to validate a new method for obtaining HM samples for FA analysis, using biological fluid sample collection pretreated sheets to adsorb drops of milk (Whatman 903 BHT-pretreated biological fluid collection sheet) as an alternative approach to collecting expressed milk. The study population included lactating mothers, enrolled between 24 and 96 h after delivery.

Results: A total of 124 breastmilk samples were analyzed using the two distinct approaches. The results of the free milk analysis were comparable to the analysis of adsorbed milk samples. The FA families saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, and omega-6 had r² values of 0.93, 0.91, 0.91, 0.86, and 0.90, respectively. Bland-Altman plots showed a high agreement between fresh and adsorbed milk samples for SFA, MUFA, PUFA, omega-3, and omega-6 with a mean bias <2% and 95% limits of agreement within -5% and +5%.

Conclusions: The results show no significant differences in fatty acid composition between fresh and adsorbed milk samples, suggesting the new method is equally effective in collecting representative samples for analysis.

Objectives: The understanding of the impact of tethered cord syndrome (TCS) on the physiology of the colorectal area is limited. Our aim was to describe anorectal and colonic motility in children with TCS and compare the findings to those of children with functional constipation (FC).

Methods: We conducted a retrospective review of children with TCS who had an anorectal manometry (ARM) performed at our institution from January 2011 to September 2023. We recorded demographics, medical and surgical history, clinical symptoms, and treatment at time of ARM, ARM findings (resting pressure, push maneuver, rectal sensation, rectoanal inhibitory reflex [RAIR], and RAIR duration), and the final interpretation of colonic manometry (CM) if performed. We identified age and sex-matched control groups of children with FC.

Results: We included 24 children with TCS (50% female) who had ARM testing (median age at ARM 6.0 years, interquartile range 4.0-11.8 years). All children had constipation at time of ARM. Nineteen children had detethering surgery before ARM was performed. No significant differences in ARM parameters were found between children who had detethering surgery before ARM and children with FC. Among the 24 children, 14 also had a CM performed (13/14 after detethering surgery). No significant differences in colonic motility were found between children with a history of TCS and children with FC.

Conclusions: Anorectal physiology and colonic motility are similar between children with a history of TCS and children with FC, suggesting that the underlying pathophysiology of defecatory disorders in children with and without history of TCS is similar.

Objectives: In gastroschisis, the intestines are exposed to amniotic fluid during pregnancy. The defect in the abdominal wall may also compress the mesentery and impair the intestinal blood supply. There is a varying degree of intestinal damage at birth. Complex gastroschisis is defined as gastroschisis with severe complications such as intestinal atresia, volvulus, necrosis and perforation. The aim of this study was to investigate long-term gastrointestinal morbidity and compare simple and complex cases.

Methods: A nation-wide retrospective cohort study with data from national registers was conducted. All children born with gastroschisis in Sweden from 1 January 1997 to 31 December 2016 were included in the study. Exposure was complex gastroschisis and the primary outcomes were intestinal failure and bowel obstruction.

Results: The study included 315 cases with gastroschisis, 260 classifieds as simple gastroschisis and 55 as complex. The median time to follow was 8 years. A significantly higher risk of developing intestinal failure (hazard ratio [HR]: 11.7) was found in complex cases. Nine percent of the complex cases underwent autologous gastrointestinal reconstructive surgery for intestinal failure, none of the simple cases did. The complex cases had a higher risk for bowel obstruction (HR: 4.3) with a higher proportion requiring surgery (18.2% vs. 6.9%) compared to simple cases.

Conclusions: This nationwide study showed that the risk for intestinal failure and bowel obstruction is significantly higher for children with complex gastroschisis compared to simple gastroschisis. Most of the events occurred during the first 2 years of life.

Objectives: Adolescents with functional abdominal pain (FAP) often experience pain and other gastrointestinal symptoms in the context of eating, which may place them at risk for eating disorders. This study compared disordered eating and its sequalae in adolescents with FAP to those with chronic headache.

Methods: Participants in this retrospective chart review study were 270 adolescents and young adults (mean age 15.9; standard deviation [SD] = 1.63; 60% female) attending an intensive, interdisciplinary pain treatment program, including 135 youth with FAP and an age- and gender-matched control group with a primary pain diagnosis of chronic headache. Information was extracted related to eating- and weight-related symptoms.

Results: Independent t-tests and χ² analyses found that compared with adolescents with chronic headache, patients with FAP showed significantly more eating pathology as reflected by scores on the Eating Attitudes Test-26 (EAT-26) (p < 0.001), endorsement of pain-related restrictive eating (p < 0.01), eating disorder history (p < 0.001), and avoidant restrictive food intake disorder (ARFID) diagnoses (p < 0.001). Compared to those with chronic headache, significantly more patients with FAP had lost 10 pounds or more (p < 0.01) and a higher proportion were underweight (p < 0.001). Among all participants, a history of exclusion diets used to manage symptoms significantly increased the risk for ARFID (p < 0.001).

Conclusion: The results of this study highlight the increased risk of eating-related concerns among youth with FAP, as well as the judicious use of exclusion diets to manage symptoms in these patients.
