Regurgitation, colic, and constipation are frequently reported Functional Gastrointestinal Disorders (FGIDs) in the first few years of life. In 2016, the diagnostic criteria for FGIDs were changed from ROME III to ROME IV. This review assesses the prevalence of the most frequent FGIDs (colic, regurgitation and constipation) among children aged 0-5 years after the introduction of the later criteria. Articles published from January 1, 2016 to May 1, 2021 were retrieved from PubMed and Google Scholar using relevant keywords. A total of 12 articles were further analyzed based on the inclusion and exclusion criteria. This review consists of two studies (17%) from the Middle East, three (25%) from Asia, two (17%) from the USA, three (25%) from Europe, and one (8%) from Africa. Three studies (25%) were based on data obtained from healthcare professionals, while the rest were parent or caregiver reports. About half of the retrieved studies used the ROME IV criteria. Among infants aged 0-6 months, the reported prevalence of colic ranged between 10-15%, whilst that of regurgitation was 33.9%, and constipation was 1.5%. Among infants aged 0-12 months, the reported prevalence of regurgitation and constipation were 3.4-25.9% and 1.3-17.7%, respectively. The reported prevalence of constipation was 1.3-26% among children aged 13-48 months and 13% among children aged 4-18 years. Despite the large variations due to differences in diagnostic criteria, study respondents and age group, the prevalence of infantile colic was higher, while that for infantile regurgitation and constipation were similar using the ROME IV or III criteria.

Extensively hydrolyzed formulas (eHFs) are recommended for the dietary management of cow's milk protein allergy (CMPA) in non-exclusively breastfed infants. Studies show that peptide profiles differ between eHFs. This short review aims to highlight the variability in peptides and their ability to influence allergenicity and possibly the induction of tolerance by different eHFs. The differences between eHFs are determined by the source of the protein fraction (casein or whey), peptide size-distribution profile and residual β-lactoglobulin which is the most immunogenic and allergenic protein in bovine milk for human infants as it is not present in human breastmilk. These differences occur from the hydrolyzation process which result in variable IgE reactivity against cow's milk allergen epitopes by subjects with CMPA and differences in the Th1, Th2 and pro-inflammatory cytokine responses elicited. They also have different effects on gut barrier integrity. Results suggest that one particular eHF-casein had the least allergenic potential due to its low residual allergenic epitope content and demonstrated the greatest effect on restoring gut barrier integrity by its effects on mucin 5AC, occludin and Zona Occludens-1 in human enterocytes. It also increased the production of the tolerogenic cytokines Il-10 and IFN-γ. In addition, recent studies documented promising effects of optional functional ingredients such as pre-, pro- and synbiotics on the management of cow's milk allergy and induction of tolerance, in part via the induction of the production of short chain fatty acids. This review highlights differences in the residual allergenicity, peptide size distribution, presence of optional functional ingredients and overall functionality of several well-characterized eHFs which can impact the management of CMPA and the ability to induce immune tolerance to cow's milk protein.

The prevalence of food allergy has increased over the last 20-30 years, including cow milk allergy (CMA) which is one of the most common causes of infant food allergy. International allergy experts met in 2019 to discuss broad topics in allergy prevention and management of CMA including current challenges and future opportunities. The highlights of the meeting combined with recently published developments are presented here. Primary prevention of CMA should start from pre-pregnancy with a focus on a healthy lifestyle and food diversity to ensure adequate transfer of inhibitory IgG- allergen immune complexes across the placenta especially in mothers with a history of allergic diseases and planned c-section delivery. For non-breastfed infants, there is controversy about the preventive role of partially hydrolyzed formulae (pHF) despite some evidence of health economic benefits among those with a family history of allergy. Clinical management of CMA consists of secondary prevention with a focus on the development of early oral tolerance. The use of extensive Hydrolysate Formulae (eHF) is the nutrition of choice for the majority of non-breastfed infants with CMA; potentially with pre-, probiotics and LCPUFA to support early oral tolerance induction. Future opportunities are, among others, pre- and probiotics supplementation for mothers and high-risk infants for the primary prevention of CMA. A controlled prospective study implementing a step-down milk formulae ladder with various degrees of hydrolysate is proposed for food challenges and early development of oral tolerance. This provides a more precise gradation of milk protein exposure than those currently recommended.

AIM: To gain insight into nutritional practices and expected growth outcomes of infants born between 34 and 36 gestational weeks defined as late preterm infants (LPT).
METHODS: An anonymous online survey among paediatricians and neonatologists from Bangladesh, Indonesia, Mexico, Nigeria, Malaysia, Singapore and Taiwan was conducted from March until October 2020. The questionnaire consisted of 40 questions on the nutritional management and expected growth outcomes of LPT in and after-hospital care.
RESULTS: Healthcare professionals from low to high Human Development (HDI) countries (n = 322) and very high HDI countries (n = 169) participated in the survey. Human milk was the preferred feeding, resulting in an adequate growth of LPT (weight, length and occipitofrontal circumference), according to a majority of respondents (low to high HDI, 179/265, 68% vs. very high HDI, 73/143, 51%; p = 0.002). The expected growth outcome was higher after-hospital discharge. Less than half of healthcare professionals started enteral feeding during the 1st hour of life. Lactation difficulties, limited access to human milk fortifiers and donor human milk, especially among low to high HDI countries, were reported as major hurdles.
CONCLUSION: Human milk is the first feeding choice for LPT. The diverse opinions on nutritional practices and expected growth outcomes among healthcare professionals indicate the necessity to develop general nutritional guidelines for LPT.

Background: The prevalence of functional constipation (FC) among children varies widely. A survey among healthcare professionals (HCPs) was conducted to better understand the HCP-reported prevalence and (nutritional) management of FC in children 12−36 months old. Methods: An anonymous e-survey using SurveyMonkey was disseminated via emails or WhatsApp among HCPs in eight countries/regions. Results: Data from 2199 respondents were analyzed. The majority of the respondents (65.9%) were from Russia, followed by other countries (Indonesia (11.0%), Malaysia (6.0%)), Mexico, KSA (5.1% (5.7%), Turkey (3.0%), Hong Kong (2.2%), Singapore (1.1%)). In total, 80% of the respondents (n = 1759) were pediatricians. The prevalence of FC in toddlers was reported at less than 5% by 43% of the respondents. Overall, 40% of the respondents reported using ROME IV criteria in > 70% of the cases to diagnose FC, while 11% never uses Rome IV. History of painful defecation and defecations < 2 x/week are the two most important criteria for diagnosing FC. In total, 33% of the respondents reported changing the standard formula to a specific nutritional solution, accompanied by parental reassurance. Conclusion: The most reported prevalence of FC in toddlers in this survey was less than five percent. ROME IV criteria are frequently used for establishing the diagnosis. Nutritional management is preferred over pharmacological treatment in managing FC.
