Multicenter Study
Dietary total antioxidant capacity is inversely associated with cardiovascular events and cardiometabolic risk factors: A cross-sectional study.
Dietary total antioxidant capacity (dTAC) has been introduced as a useful tool to quantify the antioxidant content of a diet. However, few studies have evaluated the association of dTAC with cardiovascular disease (CVD) occurrence and cardiometabolic risk factors in people with established CVD events. Thus, we aimed to investigate the presence of an association between dTAC values, cardiovascular events, and cardiometabolic risk factors in individuals with previous CVD in a Brazilian multicenter study. ⋯ The dTAC was inversely associated with hypertriglyceridemic waist phenotype, abdominal aortic aneurysm, and amputation due to arterial disease in individuals undergoing secondary care for CVD. Our results can guide strategies for the prevention of new CVD and its consequences.

Randomized Controlled Trial
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
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.

Multicenter Study Observational Study
Different muscle mass indices of the Global Leadership Initiative on Malnutrition in diagnosing malnutrition and predicting survival of patients with gastric cancer.
Malnutrition is common and related to negative prognosis in patients with gastric cancer (GC). The Global Leadership Initiative on Malnutrition (GLIM), a novel consensus for the diagnosis of malnutrition, was proposed recently. However, the roles of GLIM in diagnosing malnutrition and predicting overall survival (OS) in patients with GC have been unclear. ⋯ Our findings support the effectiveness of GLIM in diagnosing malnutrition and predicting OS in patients with GC.

The aim of this study was to understand the diet-related behaviors of Hainan centenarians and to analyze dietary factors that affect their nutritional status. ⋯ This was the first study on the dietary behaviors and nutritional status of centenarians using survey data. We highlighted the factors affecting nutritional status and provided scientific support for dietary strategies that may improve the nutritional status of the elderly population.
