Randomized Controlled Trial
Effects of ginger on serum glucose, advanced glycation end products, and inflammation in peritoneal dialysis patients.
The aim of this study was to investigate the effects of ginger supplementation on serum glucose, advanced glycation end products, oxidative stress, and systemic and vascular inflammatory markers in patients on peritoneal dialysis (PD). ⋯ This study indicated that daily administration of 1000 mg ginger reduces serum fasting glucose, which is a risk factor for hyperinsulinemia, dyslipidemia, peritoneal membrane fibrosis, and cardiovascular disease, in patients on PD.

The cerebellum is the part of the brain most involved in controlling motor and cognitive function. The surface becomes convoluted, forming folia that have a characteristic internal structure of three layers including molecular, Purkinje cell, and granular layer. This complex neural network gives rise to a massive signal-processing capability. ⋯ Treatment with natural products has been found to support improved brain function and reduce low-density-lipoprotein cholesterol level. Fish oil is one such product; among the many plant products are: Morus alba leaves, fruit, and bark; pomegranate fruit and peel; Barley β - glucans; date palm; and Allium sativum. The therapeutic potential was discussed in relation with the antilipidemic drugs, statins (HMG-CoA reductase inhibitors).

Dietary diversity is recognized as a key indicator of dietary quality. However, its association with blood antioxidant levels has not been investigated. The aim of this study was to assess the association of the dietary diversity score (DDS) with blood antioxidant status in women who attend the sports clubs of a municipality in western Tehran, Iran. ⋯ DDS is associated with blood antioxidant markers. Increasing the dietary diversity might be associated with a reduction in oxidative stress.

Vitamin A deficiency (VAD) is associated with the progression of chronic liver disease (CLD). The aim in this study was to assess levels of serum retinol and retinol-binding protein (RBP) as well as liver vitamin A stores in the presence of liver cirrhosis and hepatocellular carcinoma. ⋯ Our findings suggest serum retinol and RBP are relevant as indicators of vitamin A nutritional status in the presence of CLD. Liver vitamin A store cannot be evaluated using the RDR test because CLD causes a reduction in RBP synthesis and interferes with the mobilization of endogenous vitamin A. Considering how the patients already showed a drop in RBP relative to retinol concentrations, it is reasonable to assume vitamin A supplementation may trigger harmful effects in CLD patients.
