Ulcerative colitis is a chronic recurrent disease characterized by acute inflammation of the colonic mucosa. In Japan, a dietary supplementation product enriched with glutamine, dietary fiber, and oligosaccharide (GFO) is widely applied for enteral nutrition support. These three components have been suggested to improve intestinal health. In this study, we investigated whether GFO has suppressive effects on mucosal damage in ulcerative colitis in an experimental mouse model. ⋯ These results suggest that GFO has potential therapeutic value as an adjunct therapy for ulcerative colitis.

Obesity is a complex condition that is influenced by genetic and environmental factors and is associated with an increased risk for diabetes, hypertension, and cardiovascular diseases. Angiotensin-converting enzyme (ACE) is well characterized in the control of blood pressure. This study investigated whether the ACE insertion/deletion (I/D) polymorphism affects obesity in relation to sodium intake in children. ⋯ These findings demonstrate that the association between the ACE I/D polymorphism and obesity in relation to sodium intake is gender dependent in children.

Comparative Study
Mild zinc deficiency in male and female rats: early postnatal alterations in renal nitric oxide system and morphology.
Fetal and postnatal zinc deficiencies induce an increase in arterial blood pressure and impair renal function in male adult rats. We therefore hypothesized that these renal alterations are present in early stages of life and that there are sexual differences in the adaptations to this nutritional injury. The aim was to study the effects of moderate zinc deficiency during fetal life and lactation on renal morphology, oxidative stress, apoptosis, and the nitric oxide system in male and female rats at 21 d of life. ⋯ Zinc deficiency during fetal life and lactation induces an early decrease in renal functional units, associated with a decrease in nitric oxide activity and an increase in oxidative stress, which would contribute to increased arterial blood pressure and renal dysfunction in adulthood. The sexual differences observed in this model may explain the dissimilar development of hypertension and renal diseases in adult life.

Review Meta Analysis
Effectiveness of immunonutrient-enriched diets in the decrease of infections and mortality in the critically ill.
Pharmaconutrients have been shown in clinical and laboratory studies to modulate human and animal immune responses and thus to have potential benefits for the critically ill. However, reviews and meta-analyses continue to reflect controversy in the published research and a lack of agreement regarding these benefits. The objective of this study was to contribute to the resolution of such controversy by evaluating the effectiveness of immunonutrient-enriched diets in decreasing complications and mortality in patients with different critical illnesses. ⋯ The administration of immunomodulating nutrient-enriched diets did not change the mortality of critically ill or surgical patients, but infection complications in critically ill patients, in particular the surgical population, were decreased. Explanatory clinical trials using isolated immunomodulating nutrients in different populations of critically ill patients followed by pragmatic trials based on clinical trial results should be considered in future research.

Randomized Controlled Trial
Effects of zinc and iron supplementation fail to improve motor and language milestone scores of infants and toddlers.
To assess the effects of zinc and iron-folic acid supplementation on motor and language milestones in Nepali children. ⋯ After 1 y, neither zinc nor iron-folic acid supplementation in Nepali children improved the attainment of motor or language milestones.
