Diabetes has emerged as the biggest pandemic of our times, growing parallel to obesity. Insulin treatment regimens have been unable to completely inhibit protein glycation, which is responsible for the development of increased oxidative stress in diabetic tissues. Coupled with recent evidences that highlight the role of reactive oxygen species in the onset and progression of type 2 diabetes mellitus (T2DM), the antioxidants have taken prime focus as a possible intervention strategy. ⋯ Studies have also ascribed a role to vitamin A in up-regulating the antioxidant enzyme functions in the body. Additionally, a link has been found between diabetes and deficient vitamin A levels indicating vitamin A supplementation may have a role in T2DM biology. This review therefore focuses on the vitamin A intervention in T2DM patients having deficient in vitamin A.

The aim of this study was to assess the nutritional status and associated factors in children <5 y in the Medebay Zana District, northern Ethiopia. ⋯ The undernutrition status among children <5 y was high. Children's age group, time initiation of breast-feeding, child's sex, source of water, parents' educational status, type of food used for starting of complementary feeding, and mothers' financial decision-making ability could have an influence in undernutrition of children in this age group.

Although green and yellow vegetables have beneficial effects against type 2 diabetes, the relationship of their nutritive content with insulin resistance is poorly understood. The aim of this study was to examine the associations of serum β-carotene and retinol concentrations with glucose and insulin concentrations. ⋯ Our findings suggest that higher serum β-carotene levels, associated with higher intake of green and yellow vegetables, confer beneficial effects against insulin resistance.

Recently, new body indices, including body adiposity (BAI), a body shape (ABSI), and body roundness (BRI) indices have been developed to estimate adiposity. The aim of this study was to compare percent fat mass (%FM) with novel indices in an elite athlete population. ⋯ The newly developed body indices are limited in predicting %FM in elite athletes, particularly when compared with other commonly and readily available field methods like bioimpedance analysis or skinfold prediction models.

Muscle dysfunction and reduced heart rate variability (HRV) are common in patients with advanced liver disease, and both are related to poor outcomes. Malnutrition is also highly prevalent in these patients, however, the association between the malnutrition and HRV has not yet been assessed. The aim of this study was to evaluate the short-term HRV, functional and nutritional statuses in patients with advanced liver disease. ⋯ The study evaluated 42 patients with liver disease (62% men) and malnutrition was found in 62% of this population. The malnourished participants presented with reduced functional status, 41% decreased SDNN, and 14% greater CWI compared with well-nourished individuals (P < 0.05). Additionally, the CWI was negatively associated to SDNN (r = 0.414; P < 0.05) and gait speed (r = 0.598; P < 0.05), especially in malnourished individuals (r = 0.650; P < 0.05). These data indicate that malnourished patients with liver disease have higher cardiovascular risk related to reduced functional status, which may be associated to poor outcomes during the course of the disease before and after transplant. Another relevant aspect is that the 6MWT associated to HRV could be a useful tool to screen liver disease patients who have a higher risk for cardiovascular complications.
