Comparative Study
Assessing long-chain ω-3 polyunsaturated fatty acids: a tailored food-frequency questionnaire is better.
Polyunsaturated fatty acids (PUFAs), including the long-chain (LC) ω-3 PUFAs, are important for health. The aim was to assess if the Anti-Cancer Council of Victoria Dietary Questionnaire (ACC DQ) accurately determines PUFA intakes compared with the recently validated electronic PUFA food-frequency questionnaire (FFQ). ⋯ The validated electronic PUFA FFQ is better suited to determine ω-3 PUFA intakes than the ACC DQ.

To determine the association of in-hospital mortality in patients with enteral feeding to their glycemic status (normoglycemia, new hyperglycemia, or diabetes) and their levels of serum albumin. ⋯ The results of this study showed that newly diagnosed hyperglycemia can be considered an independent prognostic factor of in-hospital mortality in patients with enteral feeding and that there is no interaction between newly diagnosed hyperglycemia and serum albumin levels.

A decreased sensitivity to 6-n-propylthiouracil (PROP) has been shown to be associated with increased energy intake and therefore an increased body mass index, although other studies have not confirmed this association, suggesting the involvement of other factors. We investigated whether the endocannabinoid system, which also modulates hunger/satiety and energy balance, plays a role in modulating eating behavior influenced by a sensitivity to PROP. ⋯ Our data suggest that a higher disinhibition behavior in NTs may be compensated in part, in normal-weight subjects, by the decrease of peripheral endocannabinoids to downregulate the hunger-energy intake circuitry.

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.

Multicenter Study
Relation between serum folate status and blood mercury concentrations in pregnant women.
To evaluate the relation between maternal serum folate status and blood mercury in pregnant Korean women. ⋯ We found a negative association between serum folate and blood mercury concentrations in pregnant Korean women.
