Breastfed and mixed fed infants who do not consume infant cereal are at risk for inadequate iron intake:data from the feeding infants and toddlers study 2016, a cross-sectional survey.

BACKGROUND: According to the Feeding Infants and Toddlers Study (FITS), the percentage of older infants consuming infant cereal has declined from 72% of 6-11.9 month old infants in 2002 to 52% in 2016. This is especially concerning for breastfed and mixed fed infants because of their increased need for dietary sources of iron. This study explored the association between infant cereal consumption and nutrient intakes among breastfed and mixed fed infants. METHODS: FITS 2016 is the largest cross-sectional survey of food and nutrient intakes among caregivers of children less than 4 years old in the United States. For this analysis, we evaluated 24 h dietary recalls for infants 6-11.9 months who were either breastfed (no infant formula provided, n = 296) or mixed fed (breastmilk and infant formula provided, n = 102). Infants were further categorized as infant cereal consumers or non-consumers. Nutrient intakes were compared with Adequate Intakes or Estimated Average Requirements when available. Differences between cereal consumers and non-consumers were calculated using unpaired T-tests. RESULTS: Significantly fewer breastfed cereal consumers had intakes below the Estimated Average Requirement for iron (19% vs. 96%) and zinc (61% vs. 16%, p < 0.0001). Additionally, significantly more breastfed cereal consumers had intakes above the Adequate Intake level for 12 other nutrients compared to non-consumers. Among mixed fed infants, significantly fewer cereal consumers had intakes below the Estimated Average Requirement for iron compared to non-consumers (5% vs. 70%), but differences in other nutrients were not observed. CONCLUSIONS: Almost all (96%) of the breastfed infants who did not consume infant cereal had inadequate iron intakes. Even among mixed fed infants, significantly fewer infant cereal consumers had inadequate iron intakes compared to non-cereal consumers. Infant cereal is an important source of iron and other key nutrients, especially for infants receiving breastmilk.

Importance of Dietary Sources of Iron in Infants and Toddlers: Lessons from the FITS Study.

Iron deficiency (ID) affects 13.5% of 1-2 years old children in the US and may have a negative impact on neurodevelopment and behavior. Iron-fortified infant cereal is the primary non-heme iron source among infants aged 6-11.9 months. The objective of this study was to compare iron intakes of infant cereal users with non-users. Data from the Feeding Infants and Toddlers Study 2008 were used for this analysis. Based on a 24-h recall, children between the ages of 4-17.9 months were classified as 'cereal users' if they consumed any amount or type of infant cereal and 'non-users' if they did not. Infant cereal was the top source of dietary iron among infants aged 6-11.9 months. The majority of infants (74.6%) aged 6-8.9 months consumed infant cereal, but this declined to 51.5% between 9-11.9 months and 14.8% among 12-17.9 months old toddlers. Infant cereal users consumed significantly more iron than non-users across all age groups. Infants and toddlers who consume infant cereal have higher iron intakes compared to non-users. Given the high prevalence of ID, the appropriate use of infant cereals in a balanced diet should be encouraged to reduce the incidence of ID and ID anemia.

Damage to histaminergic tuberomammillary neurons and other hypothalamic neurons with traumatic brain injury.

The need for increased sleep after traumatic brain injury is a common and disabling complaint, yet its etiology is unknown. Previous studies have demonstrated diffuse damage to various hypothalamic systems, but the integrity of the histaminergic tuberomammillary nucleus, a major arousal-promoting system located in the posterior hypothalamus, has never been examined in head trauma patients. Here, we demonstrate that severe head trauma is associated with a marked loss (41%) of histaminergic neurons. Reduced histamine signaling may contribute to increased sleep need, and therapies that enhance histaminergic tone may improve arousal after head trauma or other conditions.

Impact of Providing a Combination Lipid Emulsion Compared With a Standard Soybean Oil Lipid Emulsion in Children Receiving Parenteral Nutrition: A Systematic Review and Meta-Analysis.

BACKGROUND: Soybean oil lipid emulsion may compromise immune function and promote hepatic damage due to its composition of long-chain fatty acids, phytosterols, high proportion of ω-6 fatty acids, and low α-tocopherol levels. Combination lipid emulsions have been developed using medium-chain triglyceride oil, fish oil, and/or olive oil, which provide adequate essential fatty acids, a smaller concentration of ω-6 fatty acids, and lower levels of phytosterols. The purpose of this systematic review is to determine if combination lipid emulsions have a more favorable impact on bilirubin levels, triglyceride levels, and incidence of infection compared with soybean oil lipid emulsions in children receiving parenteral nutrition. METHODS: This study comprises a systematic review of published studies. Data were sufficient and homogeneous to conduct a meta-analysis for total bilirubin and infection. RESULTS: Nine studies met the inclusion criteria. Meta-analysis showed that combination lipid emulsion decreased total bilirubin by a mean difference of 2.09 mg/dL (95% confidence interval, -4.42 to 0.24) compared with soybean oil lipid emulsion, although the result was not statistically significant (P = .08). Meta-analysis revealed no statistically significant difference in incidence of infection between the combination lipid emulsion and the soybean oil lipid emulsion groups (P = .846). None of the 4 studies that included triglyceride as an outcome detected a significant difference in triglyceride levels between the combination lipid emulsion and soybean oil lipid emulsion groups. CONCLUSION: There is inadequate evidence that combination lipid emulsions offer any benefit regarding bilirubin levels, triglyceride levels, or incidence of infection compared with soybean oil lipid emulsions.
