The relationship between various anthropometric parameters and mortality in hemodialysis (HD) patients is conflicting. Recently a new anthropometric parameter emerged, namely, body shape index (BSI). BSI is based on waist circumference (WC) but is independent of height, weight, and body mass index in predicting mortality in the general population. The aim of this study was to determine the relationship between BSI and mortality in HD patients. ⋯ In conclusion, BSI is not independently associated with mortality in HD patients.

Review Meta Analysis
Effect of short-term administration of cinnamon on blood pressure in patients with prediabetes and type 2 diabetes.
The aim of this study was to systematically review and evaluate the effect of short-term administration of cinnamon on blood pressure regulation in patients with prediabetes and type 2 diabetes by performing a meta-analysis of randomized, placebo-controlled clinical trials. ⋯ Consumption of cinnamon (short term) is associated with a notable reduction in SBP and DBP. Although cinnamon shows hopeful effects on BP-lowering potential, it would be premature to recommend cinnamon for BP control because of the limited number of studies available. Thus, undoubtedly a long-term, adequately powered RCT involving a larger number of patients is needed to appraise the clinical potential of cinnamon on BP control among patients with type 2 diabetes mellitus.

Autism has a strong genetic and environmental basis in which inflammatory markers and factors concerned with synapse formation, nerve transmission, and information processing such as brain-derived neurotrophic factor (BDNF), polyunsaturated fatty acids (PUFAs): arachidonic (AA), eicosapentaenoic (EPA), and docosahexaenoic acids (DHA) and their products and neurotransmitters: dopamine, serotonin, acetylcholine, γ-aminobutyric acid, and catecholamines and cytokines are altered. Antioxidants, vitamins, minerals, and trace elements are needed for the normal metabolism of neurotrophic factors, eicosanoids, and neurotransmitters, supporting reports of their alterations in autism. ⋯ It is suggested that maternal infections and inflammation and adverse events during intrauterine growth of the fetus could lead to alterations in the gene expression profile and proteomics that results in dysfunction of the neuronal function and neurotransmitters, alteration(s) in the metabolism of PUFAs and their metabolites resulting in excess production of proinflammatory eicosanoids and cytokines and a deficiency of anti-inflammatory cytokines and bioactive lipids that ultimately results in the development of autism. Based on these evidences, it is proposed that selective delivery of BDNF and methods designed to augment the production of anti-inflammatory cytokines and eicosanoids and PUFAs may prevent, arrest, or reverse the autism disease process.

Randomized Controlled Trial
Perioperative synbiotic therapy in elderly patients undergoing gastroenterological surgery: a prospective, randomized control trial.
Enteral administration of synbiotics has been reported to be beneficial during various types of surgery, but its clinical value in elderly surgical patients remains unclear. The aim of this study was to quantitatively evaluate the changes in gut microbiota and environment induced by perioperative synbiotic therapy, and to investigate whether it is possible to reduce infectious complications in elderly patients undergoing gastroenterological surgery. ⋯ Synbiotic therapy improved the intestinal microbial environment, and might decrease the incidence of infectious complications in elderly surgical patients.

Review
Branched-chain amino acids and ammonia metabolism in liver disease: therapeutic implications.
The rationale for recommendation of branched-chain amino acids (BCAA; valine, leucine, and isoleucine) in treatment of liver failure is based on their unique pharmacologic properties, stimulatory effect on ammonia detoxification to glutamine (GLN), and decreased concentrations in liver cirrhosis. Multiple lines of evidence have shown that the main cause of the BCAA deficiency in liver cirrhosis is their consumption in skeletal muscle for synthesis of glutamate, which acts as a substrate for ammonia detoxification to GLN and that the BCAA administration to patients with liver failure may exert a number of positive effects that may be more pronounced in patients with marked depression of BCAA levels. ⋯ In treatment of hepatic encephalopathy, simultaneous administration of the BCAA (to correct amino acid imbalance and promote ammonia detoxification to GLN) with α-ketoglutarate (to inhibit GLN breakdown to ammonia in enterocytes) and/or phenylbutyrate (to enhance GLN excretion by the kidneys) is suggested. Attention should be given to the type of liver injury, gastrointestinal bleeding, signs of inflammation, and the dose of BCAA.
