Randomized Controlled Trial
The benefits of ω-3 supplementation depend on adiponectin basal level and adiponectin increase after the supplementation: A randomized clinical trial.
The aim of this study was to analyze whether ω-3 supplementation improves cardiometabolic profile in individuals with cardiovascular risk factors and to determine the effect of adiponectin levels on these changes. ⋯ Adiponectin is shown as one of the mechanisms by which ω-3 improves cardiometabolic profile in persons with cardiovascular risk. Moreover, the benefit varies according to the adiponectin basal level and adiponectin variation after supplementation.

Review
Converting citrus wastes into value-added products: Economic and environmently friendly approaches.
Citrus fruits, including oranges, grapefruits, lemons, limes, tangerines, and mandarins, are among the most widely cultivated fruits around the globe. Its production is increasing every year due to rising consumer demand. Citrus-processing industries generate huge amounts of wastes every year, and citrus peel waste alone accounts for almost 50% of the wet fruit mass. ⋯ Citrus waste also contains high levels of sugars suitable for fermentation for bioethanol production. However, compounds such as D-limonene must be removed for efficient bioethanol production. The aim of the present article was to review the latest advances in various popular methods of extraction for obtaining value-added products from citrus waste/byproducts and their potential utility as a source of various functional compounds.

Observational Study
Optimizing protein and energy intake in hospitals by improving individualized meal serving, hosting and the eating environment.
Optimizing protein and energy intake by food in nutritional risk patients is difficult. The aim of this study was to improve the ≥75% of energy and protein requirements. We would like to see nurses take on the role of hosting the nutritional-risk patients, including focusing on bringing nutrition to the forefront in the collaboration between nurses and patients. ⋯ Only insignificant improvements to overall energy intake were seen in two of the three departments and in the overall group, and no statistical or clinically significant improvements to protein intake were observed. The relative risk of meeting 75% of energy requirements was improved in the overall group and in patients in the Department of Heart-Lung Surgery. This did not include the meeting of protein requirements. Improvements were welcomed by patients and staff. Focus on individualized nutrition from the nursing staff also improved.

Physical inactivity is frequent in patients on hemodialysis (HD), and represents a reliable predictor of morbidity and mortality. Beta-aminoisobutyric acid (BAIBA) is a contraction-induced myokine, the plasma levels of which increase with exercise and are inversely associated with metabolic risk factors. The aim of this study was to ascertain whether physical inactivity and clinical parameters relate to plasma BAIBA levels in this patient population. ⋯ Physical inactivity is highly prevalent among patients on HD and BAIBA correlates with barriers to physical activity reported by inactive patients.

The aim of this study was to evaluate the effect of different natural substances on SIRT1 expression and on AMPK and mTOR phosphorylation. Moreover, we investigated the presence of a synergistic effect between the substances. ⋯ Our results provide evidence that all compounds have the potential to stimulate SIRT1 and sustain the stimulating action of resveratrol on SIRT1, already widely reported in the literature. In this regard, we confirm the interaction of these substances also with the pathway of AMPK and mTOR, in support of the studies that highlight the importance of SIRT1/AMPK and mTOR pathway in many diseases.
