Randomized Controlled Trial
Vitamin D supplementation reduces serum lipids of children with hypertriacylglycerolemia: A randomized, triple-masked, placebo-controlled crossover trial.
This study aimed to evaluate the effect of cholecalciferol supplementation on the body composition and metabolic profile of children with hypertriacylglycerolemia. ⋯ Cholecalciferol supplementation improved the lipid profile of children with hypertriacylglycerolemia without altering body composition.

Responsiveness of one-carbon metabolites to a high-protein diet in older men: Results from a 10-wk randomized controlled trial.
Dietary strategies to promote successful aging are divergent. Higher-protein diets are recommended to preserve skeletal muscle mass and physical function. Conversely, increased B-vitamin intake, supporting one-carbon (1C) metabolism, reduces the risk of cognitive decline and cardiovascular disease. On the hypothesis that higher protein intake through animal-based sources will benefit 1C regulation by the supply of B vitamins (folate, riboflavin, and vitamins B6 and B12) and methyl donors (choline) despite higher methionine intake, this study explored the effect of a higher-protein diet on 1C metabolite status in older men compared to current protein recommendations. ⋯ Adding to the known benefits of higher protein intake in older people, this study supports a reduction of homocysteine with increased consumption of animal-based protein, although the health effects of differential response of choline metabolites to a higher-protein diet remain uncertain.

Randomized Controlled Trial
A multiple-strain probiotic product provides a better enzymatic antioxidant response in individuals with constipation in a double-blind randomized controlled trial.
Probiotics may have beneficial effects on intestinal dysbiosis. However, the effects of probiotics on redox and inflammatory responses in intestinal constipation remain unknown. The aim of this study was to investigate the effect of a multiple-strain probiotic on the redox and inflammatory responses in individuals with intestinal constipation. ⋯ Our data suggested that a multiple-strain probiotic may provide a better enzymatic antioxidant response and partially alleviate the feeling of incomplete defecation in ≥25% of bowel movements in individuals with intestinal constipation.

Randomized Controlled Trial
The impact of nutritional support on malnourished inpatients with aging-related vulnerability.
Malnutrition is highly prevalent in patients with aging-related vulnerability defined by very old age (≥80 y), physical frailty or cognitive impairment, and increases the risks for morbidity and mortality. The effects of individualized nutritional support for patients with aging-related vulnerability in the acute hospital setting on mortality and other clinical outcomes remains understudied. ⋯ Malnourished patients with aging-related vulnerability show a significant and clinically relevant reduction in the risk of mortality and other adverse clinical outcomes after individualized in-hospital nutritional support compared to routine hospital nutrition. These data support the early screening of patients with aging-related vulnerability for nutritional risk, followed by a nutritional assessment and implementation of individualized nutritional interventions.

Randomized Controlled Trial
Olive oil-based lipid emulsion is noninferior to soybean oil-based lipid emulsion in the acute care setting: A double-blind randomized controlled trial.
Olive oil (OO)-based intravenous lipid emulsion (IVLE) may have biological advantages for nutrition and inflammation status compared with soybean oil (SO)-based IVLE. We aimed to compare prealbumin levels during infusion of OO- or SO-based IVLE in patients receiving parenteral nutrition in the acute-care setting. ⋯ In this study, OO-based IVLE was not inferior to SO-based IVLE in maintaining or increasing the prealbumin level. The improvement of C-reactive protein levels and other clinical outcomes were not different for both groups.
