Clinical Trial
Gastric emptying, glucose metabolism and gut hormones: evaluation of a common preoperative carbohydrate beverage.
To study the gastric-emptying rate and gut hormonal response of two carbohydrate-rich beverages. A specifically designed carbohydrate-rich beverage is currently used to support the surgical patient metabolically. Fruit-based beverages may also promote recovery, due to natural antioxidant and carbohydrate content. However, gastric emptying of fluids is influenced by its nutrient composition; hence, safety of preoperative carbohydrate loading should be confirmed. Because gut hormones link carbohydrate metabolism and gastric emptying, hormonal responses were studied. ⋯ Fruit-based lemonade is a safe alternative for preoperative purposes. It induces a more limited glucose, insulin, and C-peptide response. Later onset in gastric emptying (B versus A: trend), lower glucagon release, and differences in beverage content and osmolarity may have contributed to those differences. Efficient emptying was reflected by early GLP-1 levels.

Metabolic syndrome (MetS) is a disorder in which obesity, insulin resistance, high blood pressure and dyslipidemia coexist. This study assessed the prevalence of MetS and its associated factors in patients who underwent orthotopic liver transplantation (OLTx). ⋯ MetS is highly prevalent among post-OLTx patients and it is predicted by older age, shorter time since transplantation, alcohol abuse as the cause of cirrhosis, excessive weight prior to OLTx, and some potentially modifiable factors such as physical activity reduction after OLTx and low intake of calcium, potassium, fiber, and folic acid.

Non-alcoholic steatohepatitis (NASH) is a common cause of liver disease, and it may progress to fibrosis or cirrhosis. The aim of this study was to investigate the effects of soy protein on hepatic steatosis and insulin resistance in NASH. ⋯ Soy protein may improve the liver function in patients with NASH by lowering lipid levels in the blood and liver, increasing the antioxidative capacity, and improving insulin resistance.
