Randomized Controlled Trial Multicenter Study
Effect of zinc on liver cirrhosis with hyperammonemia: a preliminary randomized, placebo-controlled double-blind trial.
To our knowledge, no randomized study has shown whether zinc replacement therapy is effective for hyperammonemia in liver cirrhosis; therefore, we performed a double-blind, placebo-controlled trial to examine efficacy and safety of the zinc replacement therapy. ⋯ Although this study is preliminary and includes a small sample, it is, to our knowledge, the first randomized controlled trial to show that zinc supplementation for 3 mo seems effective and safe for treating hyperammonemia in liver cirrhosis. Studies with a larger sample size are needed to confirm our findings.

Randomized Controlled Trial
Carbohydrate and glutamine supplementation modulates the Th1/Th2 balance after exercise performed at a simulated altitude of 4500 m.
The aim of this study was to evaluate the effect of carbohydrate or glutamine supplementation, or a combination of the two, on the immune system and inflammatory parameters after exercise in simulated hypoxic conditions at 4500 m. ⋯ Carbohydrate or glutamine supplementation shifts the T helper (Th)1/Th2 balance toward Th1 responses after exercise at a simulated altitude of 4500 m. The nutritional strategies increased in IL-6, suggesting an important anti-inflammatory effect.

The aim of this study was to investigate the relationship between maternal diet during pregnancy and lactation and development of atopic disorders in childhood. ⋯ This review did not find widespread or consistent links between mothers' dietary intake and atopic outcomes in their children. However, maternal consumption of Mediterranean dietary patterns, diets rich in fruits and vegetables, fish, and vitamin D-containing foods were suggestive of benefit, requiring further evaluation.

Multicenter Study
Do structural quality indicators of nutritional care influence malnutrition prevalence in Dutch, German, and Austrian nursing homes?
The aim of this study was to explore whether structural quality indicators for nutritional care influence malnutrition prevalence in the Netherlands, Germany, and Austria. Furthermore, differences in malnutrition prevalence and structural quality indicators for nutritional care nursing homes in the three countries were examined. ⋯ Structural quality indicators of nutritional care are important in explaining malnutrition variance between the Netherlands and Germany. However, they did not explain the difference in malnutrition prevalence between the Netherlands and Austria. Investigating the role of process indicators may provide insight in the role of structural quality indicators of nutritional care in explaining the malnutrition prevalence differences between the Netherlands and Austria.

Epidemiologic studies evaluating the association between the intake of vegetables and fruit and the risk for glioma have produced inconsistent results. Therefore, the aim of this study was to test the hypothesis that higher vegetable and fruit intake may have a protective effect on risk for glioma. ⋯ This analysis indicated that intake of vegetables might have a protective effect on glioma. The intake of fruit might have a protective effect on glioma in the Asian population; however, the results need to be confirmed.
