Home-based therapy with ready-to-use therapeutic food is of benefit to malnourished, HIV-infected Malawian children.

AIM: To determine if home-based nutritional therapy will benefit a significant fraction of malnourished, HIV-infected Malawian children, and to determine if ready-to-use therapeutic food (RUTF) is more effective in home-based nutritional therapy than traditional foods. METHODS: 93 HIV-positive children >1 y old discharged from the nutrition unit in Blantyre, Malawi were systematically allocated to one of three dietary regimens: RUTF, RUTF supplement or blended maize/soy flour. RUTF and maize/soy flour provided 730 kJ x kg(-1) x d(-1), while the RUTF supplement provided a fixed amount of energy, 2100 kJ/d. These children did not receive antiretroviral chemotherapy. Children were followed fortnightly. Children completed the study when they reached 100% weight-for-height, relapsed or died. Outcomes were compared using regression modeling to account for differences in the severity of malnutrition between the dietary groups. RESULTS: 52/93 (56%) of all children reached 100% weight-for-height. Regression modeling found that the children receiving RUTF gained weight more rapidly and were more likely to reach 100% weight-for-height than the other two dietary groups (p < 0.05). CONCLUSION: More than half of malnourished, HIV-infected children not receiving antiretroviral chemotherapy benefit from home-based nutritional rehabilitation. Home-based therapy RUTF is associated with more rapid weight gain and a higher likelihood of reaching 100% weight-for-height.

Home based therapy for severe malnutrition with ready-to-use food.

BACKGROUND: The standard treatment of severe malnutrition in Malawi often utilises prolonged inpatient care, and after discharge results in high rates of relapse. AIMS: To test the hypothesis that the recovery rate, defined as catch-up growth such that weight-for-height z score >0 (WHZ, based on initial height) for ready-to-use food (RTUF) is greater than two other home based dietary regimens in the treatment of malnutrition. METHODS: HIV negative children >1 year old discharged from the nutrition unit in Blantyre, Malawi were systematically allocated to one of three dietary regimens: RTUF, RTUF supplement, or blended maize/soy flour. RTUF and maize/soy flour provided 730 kJ/kg/day, while the RTUF supplement provided a fixed amount of energy, 2100 kJ/day. Children were followed fortnightly. Children completed the study when they reached WHZ >0, relapsed, or died. Outcomes were compared using a time-event model. RESULTS: A total of 282 children were enrolled. Children receiving RTUF were more likely to reach WHZ >0 than those receiving RTUF supplement or maize/soy flour (95% v 78%, RR 1.2, 95% CI 1.1 to 1.3). The average weight gain was 5.2 g/kg/day in the RTUF group compared to 3.1 g/kg/day for the maize/soy and RTUF supplement groups. Six months later, 96% of all children that reached WHZ >0 were not wasted. CONCLUSIONS: Home based therapy of malnutrition with RTUF was successful; further operational work is needed to implement this promising therapy.

Complementary food supplements to achieve micronutrient adequacy for infants and young children.

Many children in developing countries survive on a nutritionally inadequate diet. Dietary inadequacies during the complementary feeding period can be prevented by using complementary food supplements (CFSs) such as water dispersible or crushable micronutrient tablets, micronutrient sprinkles added to food just before feeding, or fortified spreads added to food just before feeding or fed as a snacks. A meeting was convened to discuss technical and operational issues related to the development of these new approaches and to identify knowledge gaps. The technical issues covered: what micronutrients to include, tolerable upper intake limits, bioavailability, micronutrient and macronutrient stability, package systems and amounts, encapsulation technologies, methods to limit or eliminate allergens, bacterial and chemical contamination, interactions between CFSs and complementary foods, and flavoring agents. Operational issues included: identifying the market positioning of CFSs, cost positioning of CFSs, regulatory requirements, CFS production and technology transfer, quality assurance, and public-private sector partnership and coordination. Intervention trials are needed to determine the efficacy of CFSs in preventing micronutrient deficiencies. Other important knowledge gaps relate to technical and operational issues. Sprinkles and tablets are produced using well-known technologies, but further research is needed to modify them for use as CFSs. Spread development is not as advanced as sprinkle and tablet development, and further research is needed to improve the technology. Although none of the products is ready for widespread use, enough information is available to set research priorities and accelerate product development and implementation.

[Management of severe malnutrition in children in tropical climates].

Severe malnutrition is defined as a weight for height index less than-3 standard deviations (SD) from the NCHS reference or the presence of edema. Without appropriate treatment, the risk of death is high. The WHO now proposes a standardized treatment protocol that consists of first treating initial complications and then two-phased feeding with two therapeutic formulas (milk F75 and milk F100) made of dried skimmed milk, oil and sugar highly supplemented with vitamins and minerals but containing no iron. Milk F75 featuring moderate protein and energy content is used for the first few days until associated infections are under control and anorexia disappears. Milk F100 featuring higher energy and protein content that allows high weight gain is subsequently used for nutritional rehabilitation. Milk F100 is gradually replaced by solid diets for home based nutritional rehabilitation.

[Infant formulas and soy protein-based formulas: current data].

For many years soy bean-based formulas (SBBF) were the only dietary product used for infants with cow's milk intolerance. At the present time, their place in infant nutrition is reduced as a result of the availability of new dietary products without lactose and/or cow's milk proteins and the recognition of soy bean protein allergy. There is no evidence that SBBF have any efficiency in infant colic. SBBF have no indication in the prevention of allergy, nor in premature infants' nutrition. Their main indication is the feeding of infants of vegetarian parents who do not want to use cow's milk products. Studies have shown that SBBF contain large quantities of phytoestrogens, particularly isoflavone. Because of experimental data suggesting a possible deleterious effect of phytoestrogens on the neuroendocrine maturation, the reduction of their content in SBBF must be considered.

Comparison of gastric emptying of a solid and a liquid nutritional rehabilitation food.

OBJECTIVE: To compare gastric emptying of a solid and a liquid nutritional rehabilitation food. DESIGN: Cross-over trial. Eight volunteers took, in random order at least 1 week apart, 2100 kJ of a solid and a liquid nutritional rehabilitation food with added labelled [13C] glycine. SETTING: Research ward for healthy volunteers. SUBJECTS: Eight healthy volunteers. METHODS: Appearance of 13CO2 was monitored in expired gas every 15 min for 240 min after meal intake and compared between solid and liquid meals. Parameters of gastric emptying were then calculated. RESULTS: Gastric half-emptying time was slightly longer for solid meal compared to liquid meal (101+/-6.0 vs 88+/-9.8 min, P=0.24). 13CO2 excretion peaked 138+/-5.3 min after the solid meal compared with 119+/-8.6 min with liquid meal (P=0.06). 13CO2 excretion was higher for the liquid food up to 110 min after the meal but then became higher for the solid food. Analysis of variance for repeated measures of 13CO2 excretion showed a significant interaction term between the type of food and time indicating a delayed elimination of 13CO2 for the solid food (P=0.018). CONCLUSIONS: Attempts to replace liquid nutritional rehabilitation foods by a solid food in malnourished patients should take into account a possible slower gastric emptying.

Dietary inadequacies observed in homeless men visiting an emergency night shelter in Paris.

OBJECTIVE: To assess the dietary intake and the nutritional status of homeless men. SETTING: A night emergency shelter in Paris, France. DESIGN: Dietary survey (48-h) including alcohol intake and a questionnaire on age, duration of homelessness, smoking habits. Subjects were also weighed and measured. SUBJECTS: Ninety-seven men aged 18-72 years (mean 43.3), of whom 54% were homeless for more than 18 months, 82% were smokers and 53% were regular and/or excessive drinkers. RESULTS: The BMI distribution was shifted towards low values, the percentage of wasted persons being four times higher than in the reference population. The mean total energy intake was 2376 kcal and included a high and highly variable percentage of energy derived from alcohol (12.0% Among drinkers, the mean ethanol intake was 90 g and there was a significant negative correlation between ethanol and non-alcoholic energy intakes. The median intakes of potassium, calcium, zinc, vitamins B1, B2, and niacin were lower than European Population Reference Intakes but only the mean intake of vitamin B1 was significantly lower. Eighty percent of non-alcoholic energy was provided by charitable organisations. For most nutrients, the nutritional density of the shelter ration was not significantly different from the density of the foods purchased by the homeless. CONCLUSIONS: These data suggest that the content of some nutrients should be increased in existing food assistance programs for homeless people in France.

Highly nutrient-dense spreads: a new approach to delivering multiple micronutrients to high-risk groups.

Using a highly fortified food is the most attractive option to bringing missing nutrients to vulnerable groups. The recent development of a highly nutrient-dense spread (HNDS) for the treatment of malnourished children may have some relevance for other high-risk groups. Traditionally, severely malnourished children are fed for 3-4 weeks during their recovery with adapted milk feeds prepared by mixing dried skimmed milk, oil and sugar with a vitamin and mineral complex. This approach, however, is difficult to implement, since these feeds are excellent growth media for bacteria, and they must be prepared and fed under close supervision. This constraint led to the development of a HNDS, which is obtained by replacing part of the dried skimmed milk with a mixture of groundnut butter and powdered lactoserum. This spread can be eaten without dilution with water and preliminary trials showed that children preferred this HNDS to traditional liquid diets. In HNDS all powdered ingredients are embedded in fat which protects vitamins against oxidation and increases the shelf life of this product. Spreads also have a very low humidity and bacteria do not grow in it. Attempts to use spreads to supplement other vulnerable groups such as moderately malnourished children and pregnant women are discussed.

[Iodine nutrition in the infant. Committee on Nutrition of the French Society of Pediatrics].

Iodine is a trace element essential for the synthesis of thyroid hormones. It is present in the human body in minute amounts (15-20 mg in adults). The thyroid is very sensitive to iodine deficiency in newborns and infants because of its very low iodine content. Daily iodine requirements in humans vary from 40 micrograms in neonates to 150 micrograms in adults. Iodine deficiency represents the first cause of avoidable mental deficiency in developed countries; it has not yet disappeared in Europe, especially in the East, where it is responsible for a high prevalence of goiter. Iodine deficiency during pregnancy increases the risk of neonatal transient hypothyroidism, with a high recall rate in programs of systematic screening for congenital hypothyroidism. Data available in France suggest that screening for iodine deficiency should be performed during pregnancy, and that the minimal iodine concentration in formula milk should be increased to 10 micrograms/100 kcal for term infants and 20 micrograms/100 kcal for premature infants. Iodine deficiency is ideally prevented by the use of iodized salt. Because of the risk of iodine overexposure and secondary transient hypothyroidism, the use of iodinated antiseptics must be avoided in premature babies and neonates as well as in pregnant and lactating women. The fight against iodine deficiency, associated with oral stable preventive iodine administration, decreases sharply the risk of thyroid cancer in case of nuclear exposure, by diminishing thyroid uptake of iodine radioactive isotopes.
