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.

Serum prealbumin has a prognostic value in several diseases, but its serum levels can be influenced by different factors. However, a multivariable analysis to test the independent effect of each has not yet, to our knowledge, been performed. The aim of this cross-sectional study was to investigate the association between prealbumin and several factors possibly affecting its serum levels to test the potential of using prealbumin as an indicator of nutritional status and short-term energy intake in patients newly diagnosed with immunoglobulin light-chain amyloidosis. ⋯ Serum prealbumin is associated with short-term energy intake independently of the presence of multiple-organ involvement and inflammation. Its serum levels should be always interpreted in light of its influencing factors, among which inflammation and liver and kidney functions appear predominant.

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.

We assessed the associations of total dairy products; milk, yogurt, and cottage cheese; cheese; and calcium with 5-y changes in components of the metabolic syndrome. ⋯ In men only, a higher consumption of dairy products was associated with positive changes in the metabolic profile in a 5-y period; a higher calcium consumption was associated with a lower 5-y increase of the BMI and waist circumference.
