Diet as an epigenetic factor in inflammatory bowel disease.

Inflammatory bowel disease (IBD) has as a main characteristic the exacerbation of the immune system against enterocytes, compromising the individual's intestinal microbiota. This inflammatory cascade causes several nutritional deficiencies, which further compromise immunological functioning and, as a result, worsen the prognosis. This vicious cycle can be interrupted as the patient's dietary pattern meets their needs according to their clinical condition, acting directly on the inflammatory process of IBD through the interaction of food, intestinal microbiota, and epigenome.

Resting energy expenditure in cirrhotic patients with and without hepatocellular carcinoma.

Background: The diagnosis of malnutrition in patients with independent hepatocellular carcinoma (HCC) varies from 20% to 50%, is related to important complications and has a direct impact on the prognosis. Determination of the resting energy expenditure (REE) has become an important parameter in this population, as it allows therapeutic adjustments to recover their nutritional status. The REE in cirrhosis, with and without HCC, is not clearly defined, and requires the identification and definition of the best nutritional approach.

Bioelectrical impedance vector analysis evaluates cellularity and hydration in cirrhotic patients.

Background: Malnutrition in cirrhotic patients is correlated with mortality and a better response to liver transplantation. However, recovery of the nutritional status in these patients is a challenge due to the difficulty in establishing a reliable nutritional diagnosis. The bioelectrical impedance vector analysis (BIVA) method appears as a feasible tool in clinical practice to define the physiological state of cirrhotic patients by assessing hydration and body cellularity.

Nutritional diagnosis of patients with hepatocellular carcinoma: what is the best method?

Introduction: malnutrition is a frequent finding among cancer patients. Despite its prognostic significance, there are still few studies evaluating the nutritional status of patients with hepatocellular carcinoma (HCC). Objectives: to evaluate the nutritional status of patients with HCC by different methods.
