Probiotics, prebiotics infant formula use in preterm or low birth weight infants: a systematic review

Malnutrition is a significant factor in predicting cancer patients?? quality of life (QoL). We systematically reviewed the literature on the role of nutritional status in predicting QoL in cancer. We searched MEDLINE database using the terms ??nutritional status?? in combination with ??quality of life?? together with ??cancer??. Human studies published in English, having nutritional status as one of the predictor variables, and QoL as one of the outcome measures were included. Of the 26 included studies, 6 investigated head and neck cancer, 8 gastrointestinal, 1 lung, 1 gynecologic and 10 heterogeneous cancers. 24 studies concluded that better nutritional status was associated with better QoL, 1 study showed that better nutritional status was associated with better QoL only in high-risk patients, while 1 study concluded that there was no association between nutritional status and QoL. Nutritional status is a strong predictor of QoL in cancer patients. We recommend that more providers implement the American Society of Parenteral and Enteral Nutrition (ASPEN) guidelines for oncology patients, which includes nutritional screening, nutritional assessment and intervention as appropriate. Correcting malnutrition may improve QoL in cancer patients, an important outcome of interest to cancer patients, their caregivers, and families.     

Preschool child feeding, health and nutritional status in Gualaceo, Ecuador

Anthropologic, survey, dietary recall and anthropometric techniques were used to study the correlates of nutritional status of preschool children under five years of age in Gualaceo Ecuador. A widespread stunting was found among the children. Nutritional status was worst among infants comprised between 12 and 23 months old but it improved between April and August, thus suggesting seasonality changes of nutritional status. The correlates of nutritional status (expressed as Z score of weight-for-age) were dietary diversity, birth-spacing, fertility, migration, household income, material goods owned, and parental education. A regression model with these variables predicted 63% of the variability in weight-for-age. The prediction of height-for-age was similar, but only predicted 43% of the variability in height-for-age. Correlates of dietary diversity, birth-spacing, fertility, and migration were child age, maternal age and arm circumference, parental education, use of birth control, household food expenditure, material goods owned, and the raising of animals. Parental education was a correlate of dietary diversity, fertility and migration. Parental education was related to change in weight-for-age in the longitudinal subset. Pre-harvest time and a pathway of illness leading to decreased dietary diversity and to decreased nutritional status in April, were suggested as important to preschool child nutritional status. Hot-cold ideology--resulting in food withdrawal during illness and restriction of high-protein and high-calorie foods--appears to be an important mechanism determining preschool child nutritional status. Breast-feeding, sanitary, higienic, birth control, and drinking (alcohol) practices were suggested as areas that could be improved, in order to improve preschool child nutritional status. Communication between parents and western health care providers was also suggested as an area for improvement.     

Nrf2 and Redox Status in Prediabetic and Diabetic Patients

The redox status associated with nuclear factor erythroid 2-related factor-2 (Nrf2) was evaluated in prediabetic and diabetic subjects. Total antioxidant status (TAS) in plasma and erythrocytes, glutathione (GSH) and malondialdehyde (MDA) content and activity of antioxidant enzymes were measured as redox status markers in 259 controls, 111 prediabetics and 186 diabetic type 2 subjects. Nrf2 was measured in nuclear extract fractions from peripheral blood mononuclear cells (PBMC). Nrf2 levels were lower in prediabetic and diabetic patients. TAS, GSH and activity of glutamate cysteine ligase were lower in diabetic subjects. An increase of MDA and superoxide dismutase activity was found in diabetic subjects. These results suggest that low levels of Nrf2 are involved in the development of oxidative stress and redox status disbalance in diabetic patients.

A nitrogen and phosphorus herbage nutrient index as a tool for assessing the effect of N and P supply on the dry matter yield of permanent pastures

In order to propose consistent decision rules for fertilizer supply, a study was made on the effect of additions of N and P fertilizers and of their interaction on the above-ground dry matter yield of pastures during spring. The interaction between N and P could occur through nutrient acquisition or nutrient efficiency for growth. We therefore characterised the herbage N and P status (N and P index) from previously established critical curves of herbage mineral content according to above-ground dry matter. First we studied the effect of N and P addition on herbage nutrient status. Secondly, we expressed the above-ground dry matter as a function of the herbage nutrient status. This study consisted of four treatments applied to four permanent pastures which had a low phosphorus availability. The results showed a positive effect of P supply on the herbage nitrogen status, which may be due to an increase of organic matter mineralization or root growth. The P herbage status decreased only if N was supplied without P. The dry matter yield was positively related to the herbage nitrogen status, but a low P herbage status reduced the slope of the relationship. For the pastures studied, the indirect effect of P supply on above-ground dry matter, revealed by an increase in N index, was greater than its direct effect. This methodology allows us to distinguish the direct and indirect effects of N and P addition on herbage growth at field level. It could be used to propose consistent rules to manage jointly both N and P supplies.
