The aim of this study was to evaluate the energy balance (EB) of patients on the waiting list for liver transplantation, using total energy expenditure (TEE) assessment and total caloric intake (TCI). ⋯ Negative EB was highly prevalent among patients on the waiting list for liver transplantation, and was associated with the severity of liver disease. Negative EB was primarily affected by low food intake. The food intake data were characterized by low overall energy and protein intake and inadequate composition of the patient's diet plan, which tended to be characterized by specific nutrient deficiencies and excesses.

The aim of this study was to estimate the concentration of cholecalciferol and 13-cis-retinoic acid (RA) in the plasma and pleural fluid of patients with tuberculosis (TB) against controls. ⋯ It was observed that in patients with TB there is a combined deficiency of cholecalciferol and 13-cis-RA compared with healthy volunteers. Because cholecalciferol and 13-cis-RA are in equilibrium with active ingredients of vitamins A and D, we feel that there is a combined deficiency of these vitamins in patients with TB. There is an evidence that concomitant vitamin A and D supplementation can kill intracellular Mycobacterium tuberculosis in vitro. Therefore, the observations made in this study can pave the path for a trial of combined supplementation of available formulations of vitamin A and D (cholecalciferol and 13-cis-RA) for novel anti-tubercular drug therapy. Because such an approach is host-based it has potential to treat even multidrug-resistant and extensively drug-resistant forms of TB.

Observational Study
Vitamin D status and body fat measured by dual-energy X-ray absorptiometry in a general population of Japanese children.
For a general population of children, data on the relationship between vitamin D status and adiposity are limited. The aim of this study was to assess the relationships between the serum concentration of 25-hydroxyvitamin D (25-OH-D) and body fat variables measured by dual-energy X-ray absorptiometry (DXA) in a general population of Japanese children, including underweight, normal, and overweight children. ⋯ Vitamin D deficiency was associated with higher total and trunk adiposities in a general population of Japanese children, particularly boys.

The goal of this study was to investigate the effect of octreotide on the expression of intestinal fat absorption-associated apolipoproteinB48 (apoB48), microsomal triglyceride transfer protein (MTP) and apolipoproteinAIV (apoAIV) in a high-fat diet-induced obesity rat model. ⋯ High-fat diet-induced obesity is associated with increased expression of apoB48, MTP, and apoAIV in the intestine. Octreotide intervention inhibited the overexpression of apoB48 and MTP, and consequently brought about reduced fat absorption and weight loss.

In critically ill patients, the optimal procedure to monitor upper gastrointestinal function is controversial. Several authors have proposed gastric residual volume (GRV) as a tool to guide enteral nutrition. The aim of this contribution is to briefly discuss corresponding studies. ⋯ For mechanically ventilated patients with a medical diagnosis at admission to the intensive care unit, monitoring of GRV appears unnecessary to guide nutrition. Surgical patients might profit, however, from a low GRV threshold (200 mL).
