Randomized Controlled Trial
Parenteral amino acid supplementation with high-dose insulin prevents hypoaminoacidemia during cardiac surgery.
Surgery triggers a stress response that produces insulin resistance and hyperglycemia. During cardiac surgery, the administration of high-dose insulin along with dextrose titration maintains normoglycemia, but dramatically decreases plasma amino acids (AAs) compared with preoperative fasting levels. Hypoaminoacidemia limits protein synthesis and prevents anabolic responses after surgery. We investigated whether parenteral infusion of AAs during and immediately after cardiac surgery would prevent hypoaminoacidemia in patients who receive high-dose insulin therapy. ⋯ AA supplementation at 35% REE, but not 20% REE, can effectively prevent hypoaminoacidemia caused by high-dose insulin therapy during cardiac surgery.

Persistent low-grade inflammation is related to the development of many chronic diseases. The dietary inflammatory index (DII®) is designed to assess the potential effects of diet on an individual's inflammation status. The aim of this study was to evaluate the construct validity of the DII using inflammation biomarkers in Japanese adults. ⋯ Null findings in women may reflect the generally lower levels of chronic systemic inflammation among Japanese versus their Western counterparts. These findings indicate that DII may be applied to measure the potential effects of diet on chronic diseases through inflammatory pathways in Japanese men.

The aim of this pre-birth cohort study was to examine the associations between maternal intake of vegetables, fruit, and antioxidants during pregnancy and behavioral problems in Japanese children 5 y of age. ⋯ Maternal intake of vegetables, fruit, and vitamin C during pregnancy may be preventive against any of the behavioral problems assessed here except for peer problems in Japanese children 5 y of age.

Reactive oxygen species level is a fundamental component in the pathogenesis of obesity that might be reduced by dietary antioxidants. Measurement of dietary total antioxidant capacity (DTAC) is regarded as a new holistic dietary index. Given the limited research on DTAC, the aim of this study was to examine the association of DTAC with obesity-related features in women. ⋯ Women with higher DTAC scores had higher risk for obesity. No association was found between DTAC and waist circumference.

Older patients are frequently subjected to prolonged hospitalization and extended bed rest, with a negative effect on physical activity and caloric intake. This results in a consistent loss of muscle mass and function, which is associated with functional decline and high mortality. The aim of this study was to investigate the effect of 1 wk of oral amino acid (AA) supplementation in older patients subjected to low mobility during hospitalization. ⋯ These results suggest that the AA mixture limits several alterations associated with low mobility in older hospitalized patients, such as length of stay, 90-d postdischarge hospitalization, and falls, preventing the loss of muscle function, as well as the increase of circulating interleukins and oxidative stress markers.
