Randomized Controlled Trial
Brazilian nut consumption by healthy volunteers improves inflammatory parameters.
The aim of this study was to investigate the effect of a single dose of Brazil nuts on the inflammatory markers of healthy individuals. ⋯ The results indicate a long-term decrease in inflammatory markers after a single intake of large portions of Brazil nuts in healthy volunteers. Therefore, the long-term effect of regular Brazil nut consumption on inflammatory markers should be better investigated.

Muscle release of the amino acid 3-methyl-histidine (3MH) is a sensitive index of myofibrillar protein overdegradation (MPO). We hypothesized that patients with chronic heart failure (CHF) could have increased muscle release of 3MH, which in turn reflects MPO, and that serum electrolyte sodium (Na(+)) and potassium (K(+)) levels may be associated with this 3MH muscle release. ⋯ The study demonstrated the existence of MPO in resting overweight patients with CHF, thereby suggesting that low serum levels of K(+) may contribute to MPO.

Thiamine or vitamin B1 deficiency diminishes thiamine-dependent enzymatic activity, alters mitochondrial function, impairs oxidative metabolism, and causes selective neuronal death. We analyzed for the first time, the role of all known mutations within three specific thiamine carrier genes, SLC19 A2, SLC19 A3, and SLC25 A19, in a patient with atrophic beriberi, a multiorgan nutritional disease caused by thiamine deficiency. ⋯ This is the first genetic study in beriberi disease. We did not detect any known mutation in any of the three genes in a sporadic dry beriberi patient. We cannot exclude a role for other known or unknown mutations, in the same genes or in other thiamine-associated genes, in the occurrence of this nutritional neuropathy.

Perioperative nutritional care is important to maintain preoperative and postoperative nutritional status. However, few reports have investigated energy metabolism after hepatectomy. The aim of this study was to determine differences in energy metabolism, blood biochemistry, and nutritional status before and after liver resection in patients with hepatocellular carcinoma (HCC) and healthy living donors for liver transplantation. ⋯ Improvement of npRQ took longer than blood biochemical data in patients with HCC and older donors. Because the recovery of npRQ is associated with donor age, careful nutritional management may be required for a longer time depending on the pathophysiological condition of each patient after hepatectomy.

The aim of this study was to evaluate glucose uptake and the contribution of glucose to fatty acid (FA) synthesis and the glycerol-3-phosphate (G3P) of triacylglycerol synthesis by interscapular brown adipose tissue (IBAT) of low-protein, high-carbohydrate (LPHC) diet-fed rats. ⋯ The LPHC diet stimulated glucose uptake, both the total rates and the rates derived from glucose-dependent FA and G3P synthesis, by increasing the insulin sensitivity and the sympathetic flux, despite a reduction in the β3-AR content.
