Effectiveness of Enteral Versus Oral Nutrition With a Medium-Chain Triglyceride Formula to Prevent Malnutrition and Growth Impairment in Infants With Biliary Atresia.

OBJECTIVES: The aim of this study was to compare the effectiveness of oral (PO) versus enteral nutrition (EN) medium-chain triglyceride (MCT) containing-formula to prevent malnutrition and growth impairment in infants with biliary atresia (BA) waiting for a liver transplant. METHODS: A total of 15 infants, 3 to 9 months old with BA were included. They were randomly assigned to either PO or EN. For 12 weeks, both groups received an MCT formula fortified with glucose polymers and corn oil to reach a caloric density between 0.8 and 1 kcal/mL. The formula given to the PO group was administered ad libitum and that given via EN was infused through a nasogastric tube to reach 140% of the energy intake recommended by the Dietary Recommended Intake guidelines. Protein intake was adjusted to 4 to 5 g/kg present weight. Outcome variables were growth and nutritional status evaluated periodically by anthropometric indicators. Biochemical and hematological variables were evaluated through the study. RESULTS: Baseline clinical, nutritional, biochemical, and hematological variables showed no differences between the study groups. Baseline length/age was <-2 SD in 10 of the 15 patients; in the PO group, it fell <-3 SD, whereas in the EN group, it remained stable. Head circumference z score dropped 0.6 SD in the PO group, whereas in the EN group it remained stable. Triceps skinfold values improved in the infants taking EN, P < 0.001. The frequency of adverse effects--respiratory infection and diarrhea--was higher in the EN group. No biochemical or hematological differences were observed between the study groups throughout the study. CONCLUSIONS: A 12-week EN trial with an MCT-fortified formula prevented malnutrition and growth impairment in infants with BA waiting for a liver transplant.

Enteral Feedings in Children: Sorting Out Tubes, Buttons, and Formulas.

Enteral nutrition (EN) is the provision of food or nutrients beyond the esophagus via a tube either to the stomach or small intestines. Choosing the route, method, and formula for administration of EN to infants and children is complicated by the increasing options available. Indications and contraindications change as surgical procedures and medical treatments advance. Human milk remains the normative standard for infant formulas; if a safe supply is available, it is recommended as optimal nutrition for infants, including via enteral tube access. For infants without an available supply of human milk and children older than 12 months, a wide variety of formulas are available, including the renewed interest in formulas using cooked table foods. This article presents the different methods of EN access placement, maintenance, formula recommendations, and advancement of EN. It is important for healthcare professionals to be aware of the options and recommendations for EN.

An Opinion on "Staging" of Infant Formula: A Developmental Perspective on Infant Feeding.

Breast milk is a dynamic fluid with compositional changes occurring throughout the period of lactation. Some of these changes in nutrient concentrations reflect the successively slowing growth rate and developmental changes in metabolic requirements that infants undergo during the first year of life. Infant formula, in contrast, has a static composition, intended to meet the nutritional requirements of infants from birth to 6 or 12 months of age. To better fit the metabolic needs of infants and to avoid nutrient limitations or excesses, we suggest that infant formulas should change in composition with the age of the infant, that is, different formulas are created/used for different ages during the first year of life. We propose that specific formulas for 0 to 3 months (stage 1), 3 to 6 months (stage 2), and 6 to 12 months (stage 3) of age may be nutritionally and physiologically advantageous to infants. Although this initially may impose some difficult practical/conceptual issues, we believe that this staging concept would improve nutrition of formula-fed infants and, ultimately, improve outcomes and make their performance more similar to that of breast-fed infants.

Introduction of pasteurized/raw cow’s milk during the second semester of life as a risk factor of type 1 diabetes mellitus in school children and adolescents / Introducción de leche entera pasteurizada/no pasteurizada de vaca en el segundo semestre de la vida y riesgo de diabetes mellitus tipo 1 en escolares y adolescentes

Objective: to demonstrate that type 1 diabetes mellitus (T1DM) in school children and adolescents is associated with the early introduction of pasteurized/raw cow’s milk in the second semester of life. Material and methods: this non-probabilistic study included 150 subjects (75 patients and 75 controls), divided according to sex and age (range, 6 to 16 years). T1DM was considered to be a dependent variable, and pasteurized/raw cow’s milk (P/RCM) was considered to be an independent variable in the study. The statistical analyses included chi-squared test, odds ratio and 95% confidence intervals. Results: the subjects were 51% male, age 11±3.2 years, and 80% were breastfed, 18% were exclusively breastfed, and 13% received pasteurized/raw cow’s milk. The children receiving P/RCM had a higher risk of T1DM [OR, 3.9 (1.2-12.8)]. The presence of T1DM was three times higher in those consuming P/RCM vs. those receiving follow-up formula [RM, 3.2 (1.03-10.07)]. Conclusions: introducing pasteurized/raw cow’s milk in the second semester of life increased by four times the likelihood of developing T1DM in children and adolescents (AU)

Infant-feeding practices among African American women: social-ecological analysis and implications for practice.

Despite extensive evidence supporting the health benefits of breastfeeding, significant disparities exist between rates of breastfeeding among African American women and women of other races. Increasing rates of breastfeeding among African American women can contribute to the improved health of the African American population by decreasing rates of infant mortality and disease and by enhancing cognitive development. Additionally, higher rates of breastfeeding among African American women could foster maternal-child bonding and could contribute to stronger families, healthier relationships, and emotionally healthier adults. The purpose of this article is twofold: (a) to use the social-ecological model to explore the personal, socioeconomic, psychosocial, and cultural factors that affect the infant feeding decision-making processes of African American women and (b) to discuss the implications of these findings for clinical practice and research to eliminate current disparities in rates of breastfeeding.

Does type of feeding in infancy influence lipid profile in later life?

OBJECTIVE: To compare the lipid profile of exclusively breastfed and mixed-fed, term, appropriate for gestation age infants from 6 mo to 1 y of age. METHODS: This prospective comparative study included one hundred ninety nine consecutive term healthy infants; 105 on exclusive breastfeeding (EBF) and 94 receiving mixed feeding (MF). These children were recruited at 6 mo of age and followed till 1 y of age. Serum lipid levels of babies were determined at recruitment (6 mo), 9 mo and 1 y of age. Statistical analysis was carried out using SPSS software. RESULTS: The mean total cholesterol (TC) at 6 mo in exclusively breastfed group (156.38 ± 50.42 mg/dl) was significantly higher than mixed fed group (139.5 ± 37.59 mg/dl). At 9 mo, high density lipoprotein cholesterol (HDL-C) and triglycerides (TG) levels were significantly different in EBF group than MF group. The lipid profile of both group of babies was comparable at 1 y of age. The HDL-C: LDL-C ratio was significantly different between the two groups (higher in breastfed group) at 1 y. CONCLUSIONS: The present study highlights differential lipid profile of exclusively breastfed infants and mixed fed infants.

Evaluation of hypoallergenicity of a new, amino acid-based formula.

UNLABELLED: The American Academy of Pediatrics (AAP) defined a formula as hypoallergenic if it ensures with 95% confidence that 90% of infants with confirmed cow's milk allergy (CMA) will not react with defined symptoms under double-blind, placebo-controlled conditions. This study's objective was to determine whether a new amino acid-based formula (AAF) meets the AAP hypoallergenicity criteria. METHODS: Children with CMA were randomized to double-blind placebo-controlled food challenges (DBPCFC) with a new AAF and a commercial AAF in crossover fashion followed by an at-home open challenge with the new AAF. Allergic reactions were assessed using a scoring system. RESULTS: Thirty-three subjects completed DBPCFCs with both formulas without acute allergic reactions. The lower bound 95% confidence interval for hypoallergenicity was 91.3%. No unusual stool patterns, allergic symptoms, or signs of intolerance were reported during the open challenge. CONCLUSION: . The new AAF meets AAP hypoallergenicity criteria and can be recommended for the management of CMA.

Nutritional status of breast-fed and non-exclusively breast-fed infants from birth to age 5 months in 8 Chinese cities.

This study aimed to assess the nutritional status of infants aged 0 to 5 months by different feeding approaches. A cross-sectional study on infant nutrition was performed in eight cities in China. A total of 622 infants from birth to 2 months of age and 456 infants from 3 months to 5 months of age were included in this study. Mix-fed infants received breast milk and complementary foods from birth to 2 months of age. Approximately 38.2% of mix-fed infants received excessive vitamin A, and 15.6% of infants exceeded the tolerable upper intake levels (ULs) of zinc. For artificially fed infants who received only complementary foods, approximately 20% and 12.5% infants received inadequate dietary vitamin A and zinc intakes, respectively. The vitamin A and zinc intakes of half of the infants exceeded the ULs. Results showed that the usual intake distribution of the infants from 3 months to 5 months of age were similar to that of the infants from birth to 2 months of age. The common vitamin A and zinc intakes were also severely imbalanced. In addition, higher disease prevalence and lower Z scores of length-forage, weight-for-age, and weight-for-length were found in artificially fed infants and mix-fed infants compared with those in breast-fed infants. In conclusion, the usual nutrient intakes were adequate for the majority of Chinese infants, except for an important number of infants at risk for imbalance of vitamin A and zinc intakes.

Safety and tolerance of a new extensively hydrolyzed rice protein-based formula in the management of infants with cow's milk protein allergy.

UNLABELLED: Guidelines recommend the use of extensively hydrolyzed cow's milk protein-based formulas (eHF) in the treatment of infants with cow's milk protein allergy (CMPA). Extensively hydrolyzed rice protein infant formula (eRHF) has recently become available and could offer a valid alternative. A prospective trial was performed to evaluate the hypo-allergenicity and safety of a new eRHF in infants with a confirmed CMPA. Patients were fed the study formula for 6 months. Clinical tolerance of the eRHF was evaluated with a symptom-based score (SBS) and growth (weight and length) was monitored. Forty infants (mean age, 3.4 months; range, 1-6 months) with CMPA confirmed by a food challenge were enrolled. All infants tolerated the eRHF and the SBS significantly decreased as of the first month of intervention. Moreover, the eRHF allowed a catch-up to normal weight gain as of the first month as well as a normalization of the weight-for-age, weight-for length, and BMI z-scores within the 6-month study period. CONCLUSION: In accordance with current guidelines, this eRHF was tolerated by more than 90 % of children with proven CMPA with a 95 % confidence interval. This eRHF is an adequate and safe alternative to cow milk-based eHF.

Infant formula samples: perinatal sources and breast-feeding outcomes at 1 month postpartum.

The purpose was to describe sources of infant formula samples during the perinatal period and assess their associations with breast-feeding outcomes at 1 month postpartum. Subjects included expectant mothers who anticipated breast-feeding at least 1 month. Infant feeding history and sources of formula samples were obtained at 1 month postpartum. Associations between sources and breast-feeding outcomes were assessed using partial correlation. Of the 61 subjects who initiated breast-feeding, most were white (87%), married (75%), college-educated (75%), and planned exclusive breast-feeding (82%). Forty-two subjects (69%) continued breast-feeding at 1 month postpartum. Subjects received formula samples from the hospital (n = 40; 66%), physician's office (n = 10; 16%), and mail (n = 41; 67%). There were no significant correlations between formula samples from the hospital, physician's office, and/or mail and any or exclusive breast-feeding at 1 month (P > .05). In addition to the hospital, a long-standing source of formula samples, mail was also frequently reported as a route for distribution. The lack of statistically significant associations between formula samples and any or exclusive breast-feeding at 1 month may be related to small sample size and unique characteristics of the group studied.

HIV disclosure to partners and family among women enrolled in prevention of mother to child transmission of HIV program: implications for infant feeding in poor resourced communities in South Africa.

The introduction of routine HIV counselling and testing (HCT) has increased the number of pregnant women being tested and receiving prevention of mother to child transmission of HIV (PMTCT) interventions in South Africa. While many women may enroll in PMTCT, there are barriers that hinder the success of PMTCT programmes. The success of the PMTCT is dependent on the optimal utilization of PMTCT interventions which require the support of the woman's partner, and other members of her family. We conducted focus groups interviews with 25 HIV-positive post-natal women enrolled in PMTCT, in the City of Tshwane, South Africa. The study explored HIV-positive status disclosure to partners and significant family members and assessed the effect of nondisclosure on exclusive infant feeding. Most women disclosed to partners while few disclosed to significant family members. Most women initiated mixed feeding practices as early as one month and reported that they were pressurized by the family to mix feed. Mixed feeding was common among women who had not disclosed their HIV-positive status to families, and women who had limited understanding of mother to child transmission of HIV. Women who disclosed to partners and family were supported to adhere to the feeding option of choice. Health providers have a critical role to play in developing interventions to support HIV pregnant women to disclose in order to avoid mixed feeding. Improving the quality of information provided to HIV-positive pregnant women during counselling will also reduce mixed feeding.

Effect of early limited formula on duration and exclusivity of breastfeeding in at-risk infants: an RCT.

BACKGROUND AND OBJECTIVES: Recent public health efforts focus on reducing formula use for breastfed infants during the birth hospitalization. No previous randomized trials report the effects of brief early formula use. The objective of the study was to determine if small formula volumes before the onset of mature milk production might reduce formula use at 1 week and improve breastfeeding at 3 months for newborns at risk for breastfeeding problems. METHODS: We randomly assigned 40 exclusively breastfeeding term infants, 24 to 48 hours old, who had lost ≥5% birth weight to early limited formula (ELF) intervention (10 mL formula by syringe after each breastfeeding and discontinued when mature milk production began) or control (continued exclusive breastfeeding). Our outcomes were breastfeeding and formula use at 1 week and 1, 2, and 3 months. RESULTS: Among infants randomly assigned to ELF during the birth hospitalization, 2 (10%) of 20 used formula at 1 week of age, compared with 9 (47%) of 19 control infants assigned during the birth hospitalization to continue exclusive breastfeeding (P = .01). At 3 months, 15 (79%) of 19 infants assigned to ELF during the birth hospitalization were breastfeeding exclusively, compared with 8 (42%) of 19 controls (P = .02). CONCLUSIONS: Early limited formula may reduce longer-term formula use at 1 week and increase breastfeeding at 3 months for some infants. ELF may be a successful temporary coping strategy for mothers to support breastfeeding newborns with early weight loss. ELF has the potential for increasing rates of longer-term breastfeeding without supplementation based on findings from this RCT.

Fermentation products: immunological effects on human and animal models.

Infant formulas have been shown to influence the development of the gut microbiota. Besides the probiotic- and prebiotic-containing formulas, fermented milk-based infant formulas offer an additional means for modulation of gut immunity and/or gut microbiota. These formulas are produced by the fermentation of cow's milk with specific lactic acid bacteria strains, followed by heat treatment; they do not contain viable bacteria or added prebiotic oligosaccharides but contain specific products resulting from the fermentation process. This review is focused on the effects of fermentation products, distinguishing them from those of living bacteria and prebiotic compounds on the immune system. Besides the possible modulation of gut microbiota composition, in vitro and in vivo studies suggest that specific fermentation products can actively participate in the establishment of immune balance and oral tolerance. Although further research is needed to confirm the clinical benefits observed in infants to better characterize the active fermentation compounds and to delineate the involved pathways, these fermented formulas appear to deserve interest.
