OBJECTIVES: To systematically evaluate the effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical development in preterm infants. METHODS: A computerized search was performed in the databases including China National Knowledge Infrastructure, Wanfang Data, Weipu, PubMed, Embase, and the Cochrane Library to identify randomized controlled trials of the effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical growth in preterm infants. RevMan 5.3 software was used to perform a Meta analysis for the included studies. RESULTS: A total of 7 randomized controlled studies were included. The results of Meta analysis showed that compared with the whole protein formula, the prophylactic use of hydrolyzed protein formula could reduce the risk of neonatal necrotizing enterocolitis (RR=0.40, P=0.04) and feeding intolerance (RR=0.40, P=0.005), and had no significant effect on the growth of weight, length and head circumference (P>0.05). CONCLUSIONS Compared with the whole protein formula, the prophylactic use of hydrolyzed protein formula in preterm infants may reduce the occurrence of necrotizing enterocolitis and feeding intolerance, and can meet the nutrient requirement of physical development. However, the evidence is limited, and the results of this study cannot support the routine prophylactic use of hydrolyzed protein formula in preterm infants.

Objective: To assess the risk of foodborne diseases caused by Cronobacter sakazakii in infant formula powder from retail to feeding and provide formulate suggestions for safe feeding of infants at home. Methods: This study used the special monitoring and risk monitoring data of infant formula powder in Heilongjiang Province and combined data at home and abroad. The @RISK software was used to evaluate the disease risk caused by Cronobacter sakazakii in the process of infant formula powder from retail to feeding. Results: According to the results of this quantitative risk assessment, the risk of foodborne diseases caused by Cronobacter sakazakii at the current consumption pattern in Heilongjiang Province was 5.158×10^-5 persons/million (40.0 ℃ and 50.0 ℃), 1.072×10^-7 persons/million (60.0 ℃), 5.544×10^-14 persons/million (70.0 ℃). When the feeding time of infant formula powder was adjusted to 0-2 h and 2-3 h respectively, the above prediction results did not change. When it was adjusted to 3-4 h, the risk increased. If it was adjusted to 4-24 h, the number of Cronobacter sakazakii increased by 14-24 orders of magnitude at room temperature. If the initial pollution concentration (after flushing) was adjusted to 1 MPN/ml, the average disease risk per meal was 805.7 persons/million (40.0 ℃ and 50.0 ℃), 1.7 persons/million (60.0 ℃) and 9.1 × 10^-7 persons/million (70.0 ℃). The results of sensitivity analysis showed that the water temperature (70.0 ℃), initial pollution concentration, room storage time and temperature were important factors of risk. Conclusion: Controlling the contamination level of Cronobacter sakazakii in infant formula powder, controlling the feeding time within 3 h, storing in refrigerator and mixing with water with temperature not lower than 70.0 ℃ are effective measures to prevent infants from eating infant formula powder infected by Cronobacter sakazakii.

formula. In particular, the GOS/FOS combination is the most studied. Maintaining a healthy microbiome is essential to promote homeostasis of the gut and other organs. With more than 1,000 different microbial species in the gut, it is likely more feasible to modify the gut microbiota through the use of certain prebiotic mixtures rather than supplementing with a particular probiotic strain. In this review, we discuss the latest clinical evidence regarding prebiotics and its role in gut immunity, allergy, infections, inflammation, and functional gastrointestinal disorders.]]>

BACKGROUND: Although the clinical importance of the immunological benefits of breastfeeding has been emphasized for decades, their direct relationship with acute pyelonephritis (APN) is still not clear. Our goal was to determine whether breastfeeding truly provides protection against APNs, while investigating the effects of other factors such as sex, age, mode of delivery, and birth weight on APN.METHODS: A total of 62 infants under 6 months of age who had both microbiologically and radiologically-confirmed APN were enrolled in the case group. Healthy infants (n = 178) who visited the hospital for scheduled vaccinations were enrolled in the control group. The following participant characteristics were compared between the case and control groups: age, sex, birth order among siblings, feeding methods, weight percentile by month, birth weight percentile by gestational age, gestational age at birth, and mode of delivery.RESULTS: Babies exclusively fed with manufactured infant formulae before 6 months of age had significantly higher risk for APN than breastfed or mixed-fed infants (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.687–7.031; P = 0.001). Firstborn babies had lower risk for APN than 2nd- or 3rd-born babies (OR, 0.43; 95% CI, 0.210–0.919). Other factors that increased the risk for APN were low birth weight percentiles (OR, 8.33; 95% CI, 2.300–30.166) and birth via caesarean section (OR, 2.32; 95% CI, 1.097–4.887). There were more preterm births in the case group (10.9% vs. 1.7%; P = 0.002), but this did not increase the risk for APN (OR, 4.47; P = 0.063).CONCLUSION: Feeding exclusively with formula before 6 months of age was related to higher risk for APN, which demonstrates that breastfeeding has a protective effect against APN. The other risk factors for APN were birth order (≥ 2nd-born), low birth weight, and birth via caesarean section.

PURPOSE: The aim of this study was to identify the minimally meaningful dosage of inulin leading to a prebiotic effect in Indonesian infants. METHODS: In a randomized controlled double-blinded, parallel, 3-arm intervention study, 164 healthy formula-fed infants aged 3 to 5 months first obtained formula-A (without inulin) during a 4-week adaptation period. Subsequently, 142 subjects were subjected to a 4-week feeding period by administering either formula-A (no inulin), formula-B (0.2 g/100 mL inulin) or formula-C (0.4 g/100 mL inulin). The primary outcome parameter was %-bifidobacteria in faecal samples determined using quantitative polymerase chain reaction analyses. Secondary outcome parameters were faecal %-lactobacilli, pH and stool frequency, and consistency. Growth and tolerance/adverse effects were recorded as safety parameters. RESULTS: Typical %-bifidobacteria and %-lactobacilli at the end of the adaptation period in the study population were 14% and 2%, respectively. For faecal pH, significant differences between formula groups A vs. C and A vs. B were found at the end of the intervention period. Testing for differences in faecal %-bifidobacteria and %-lactobacilli between groups was hampered by non-normal data set distributions; no statistically significant differences were obtained. Comparisons within groups revealed that only in formula group C, all the three relevant parameters exhibited a significant effect with an increase in faecal %-bifidobacteria and %-lactobacilli and a decrease in pH. CONCLUSION: A consistent prebiotic effect along with a decrease in pH and increase in %-bifidobacteria and %-lactobacilli was found only in the group administered 0.4 g inulin/100 mL.

The World Health Organization recommends that infants should be exclusively breastfed for the first 6 months of life to provide optimal nutrition in this critical period of life. After this, infants should receive nutritionally adequate and safe complementary foods while breastfeeding continues for up to 2 years of age or beyond. For nonbreastfed infants, infant formula is an available option to provide the nutrition needed. Infant formula is usually prepared from industrially modified cow's milk and processed to adjust for the nutritional needs of infants. However, cow's milk is one of the most common causes of food allergy, affecting 2%–5% of all formula-fed infants during their first year of life. One strategy to prevent cow's milk allergy in nonbreastfed infants is the use of partially hydrolyzed formula (pHF) in high-risk infants, which are infants born in families with atopic disease. However, based on an epidemiological study, approximately half of the infants who develop allergy are not part of the at-risk group. This is because the non-at-risk group is significantly larger than the at-risk group and the non-at-risk infants have approximately 15% risk of developing allergies. This study aimed to evaluate the effects of partially hydrolyzed whey formula (pHF-W) in nonbreastfed infants and determine whether pHF-W can prevent atopic disease in high-risk infants and can be used as routine starter formula regardless of the allergy risk status.

Aluminum (Al) is the third most abundant element in the earth's crust and is omnipresent in our environment, including our food. However, with normal renal function, oral and enteral ingestion of substances contaminated with Al, such as antacids and infant formulae, do not cause problems. The intestine, skin, and respiratory tract are barriers to Al entry into the blood. However, contamination of fluids given parenterally, such as parenteral nutrition solutions, or hemodialysis, peritoneal dialysis or even oral Al-containing substances to patients with impaired renal function could result in accumulation in bone, parathyroids, liver, spleen, and kidney. The toxic effects of Al to the skeleton include fractures accompanying a painful osteomalacia, hypoparathyroidism, microcytic anemia, cholestatic hepatotoxicity, and suppression of the renal enzyme 25-hydroxyvitamin D-1 alpha hydroxylase. The sources of Al include contamination of calcium and phosphate salts, albumin and heparin. Contamination occurs either from inability to remove the naturally accumulating Al or from leeching from glass columns used in compound purification processes. Awareness of this long-standing problem should allow physicians to choose pharmaceutical products with lower quantities of Al listed on the label as long as this practice is mandated by specific national drug regulatory agencies.

Human breast milk contains numerous biomolecules. Human milk oligosaccharides (HMOs) are the third most abundant component of breast milk, after lactose and lipids. Amongst the synthetized HMOs, 2′-fucosyllactose (2′-FL) and lacto-N-neotetraose (LNnT) are widely studied and are considered safe for infant nutrition. Several studies have reported the health benefits of HMOs, which include modulation of the intestinal microbiota, anti-adhesive effect against pathogens, modulation of the intestinal epithelial cell response, and development of the immune system. The amount and diversity of HMOs are determined by the genetic background of the mothers (HMO secretors or non-secretors). The non-secretor mothers secrete lower HMOs than secretor mothers. The breastfed infants of secretor mothers gain more health benefit than those of non-secretor mothers. In conclusion, supplementation of infant formula with 2′-FL and LNnT is a promising innovation for infant nutrition.

PURPOSE: To compare the effectiveness of the magnesium (Mg)-enriched formula vs. control formula in constipated infants. METHODS: An open-label, interventional, and the comparator-controlled study was conducted to evaluate the effectiveness of the Mg-enriched formula in formula-fed infants ≤6 months old presenting with functional constipation according to modified Rome IV criteria. Infants were randomized 1:1 to intervention or control formula for 30 days. Parents recorded stool consistency (hard, normal, or watery) and frequency on days 1–7 and 23–29. Physicians recorded patient baseline characteristics and performed the clinical examination at the time of three patient visits (baseline, day 8, and 30). RESULTS: Of the 286 recruited infants, 143 received the Mg-rich formula and 142 received the control formula. After 7 days, significantly more infants had stools with normal consistency with the Mg-rich formula compared to the infants fed with the control formula (81.8% vs. 41.1%; p<0.001). The number of infants passing one or more stools per day was increased at day 7 in the Mg-rich formula group (86.7% vs. 68.2%; p<0.001). At days 7 and 29, >25% of infants responded completely to the Mg-rich formula compared to <5% of infants fed with the control formula (p<0.001). Parents of infants in the Mg-rich formula group were very satisfied with the treatment (80.8% vs. 10.2%), with the majority willing to continue treatment after 30 days (97.9% vs. 52.6%; p<0.001). CONCLUSION: The Mg-rich formula significantly improved stool consistency and frequency compared to the control formula in constipated infants.
