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.

Food-based strategies need to be developed to improve the vitamin D status of individuals. Recent studies identified ultraviolet B irradiation as an efficient method to enrich mushrooms and eggs with vitamin D. The aim of this study was to determine whether free-range farming of hens could provide a valuable method to produce vitamin D-enriched eggs. ⋯ Free-range farming offers an efficient alternative to fortify eggs with vitamin D, provided that farming conditions are sufficiently attractive for hens to range outside.

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.

Randomized Controlled Trial
Probiotic supplementation improves inflammatory status in patients with rheumatoid arthritis.
Rheumatoid arthritis (RA) is an inflammatory autoimmune disease in which the gut microbiota is altered. Probiotics are microorganisms that can normalize gut microbiota; thus, they may help to alleviate RA symptoms. The objective of the present clinical trial was to assess the effects of probiotic supplementation on disease activity and inflammatory cytokines in patients with RA. ⋯ L. casei 01 supplementation improved the disease activity and inflammatory status of patients with RA. Further studies are warranted to confirm these results, and such confirmation may lead to the introduction of probiotics as adjunctive therapy for this population.
