The Codex Alimentarius Commission of the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) develops food standards, guidelines and related texts for protecting consumer health and ensuring fair trade practices globally. The major part of the world's population lives in more than 160 countries that are members of the Codex Alimentarius. The Codex Standard on Infant Formula was adopted in 1981 based on scientific knowledge available in the 1970s and is currently being revised. As part of this process, the Codex Committee on Nutrition and Foods for Special Dietary Uses asked the ESPGHAN Committee on Nutrition to initiate a consultation process with the international scientific community to provide a proposal on nutrient levels in infant formulae, based on scientific analysis and taking into account existing scientific reports on the subject. ESPGHAN accepted the request and, in collaboration with its sister societies in the Federation of International Societies on Pediatric Gastroenterology, Hepatology and Nutrition, invited highly qualified experts in the area of infant nutrition to form an International Expert Group (IEG) to review the issues raised. The group arrived at recommendations on the compositional requirements for a global infant formula standard which are reported here.
Cow's milk protein (CMP) allergy was investigated in 25 children (age-range 3 months to 11 years) with chronic constipation. A diagnosis of constipation was made on the basis of a history of painful elimination of hard stools for at least 1 month, whether or not associated with a reduced frequency of stools or soiling. The children were evaluated using clinical parameters and the following laboratory tests: total serum immunoglobulin E (IgE); specific IgE (radioallergosorbent test [RAST]) for whole cow's milk, alpha-lactoalbumin, beta-lactoglobulin, and a food group; and skin-prick tests with whole milk, alpha-lactoalbumin, beta-lactoglobulin, and casein. Following the evaluation, the children were submitted to a CMP-free diet for a period of 4 weeks. In seven patients (28%), constipation disappeared during the CMP-free diet and reappeared within 48-72 h following challenge with cow's milk. In two infants a rectal biopsy revealed allergic colitis and they therefore did not undergo the challenge. High serum levels of total IgE were observed in five of the children who showed a clinical improvement (71%), a positive skin-test in two (29%), and detectable specific IgE in two (29%). These results suggest that CMP allergy or intolerance should be considered as a cause of chronic refractory constipation in children, although the underlying mechanism still require further investigation.
This study focused on the under-five population of the Alto Xingu region in Brazil, with the following objectives: (1) to evaluate height and weight increment from the first through the fourth years of life and (2) to compare nutritional status in 1980 and 1992. Height and weight increases were evaluated in 81 children. Weight and height were measured in 264 children evaluated in 1980 and in 172 in 1992 (< 10 years of age). Median Z-scores in the first and fourth years of life, respectively, showed: (1) a decrease in weight-for-age, (-0.12 in the first year and -0.51 in the fourth year of life; p = 0.002); (2) a decrease in weight-for-height (+1.31 and +0.08; p < 0.001); (3) an increase in height-for-age (-1.50 and -0.94; p < 0.001). Median Z-scores in 1980 and 1992 showed: (1) no change in weight-for-age (-0.61 in 1980 and -0.62 in 1992; p = 0.90); (2) no change in weight-for-height (+0.27 and +0.34; p = 0.10); and (3) a decrease in height-for-age (-1.04 and -1.22; p = 0.02). Height-for-age increased and weight-for-height decreased between the first and fourth years of life. A decrease in height-for-age was observed from 1980 to 1992, demonstrating the importance of nutritional surveillance among the population of the Alto Xingu.
Asymptomatic giardiasis did not affect the intestinal absorption of iron and the hemoglobin response to oral iron therapy in iron-deficient anemic children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
