Night fasting as an alternative to improve nutritional support and glycaemic control in hospitalised patients with exclusive enteral nutrition.

Background: Enteral nutrition (EN) assists in the nutritional status of hospitalised patients unable to feed orally. The aim of this study was to determine which method-continuous EN or discontinuous EN, a diet in which the infusion is discontinued for 4h during the night,-is more effective in meeting nutrient recommendations and improving glycaemic control and biochemical parameters related to protein anabolism.

Methods: Patients were divided into two groups: discontinuous (EN administered in mL/h, 18h/day, 4-h night fasting) and continuous (EN administered in mL/h, 22h/day).

EFFECT OF ANTIOXIDANT POTENTIAL ON SEVERITY OF CIRRHOSIS IN HUMANS.

Background/aims: to examine the relationship between the antioxidant potential and severity parameters of cirrhosis in humans.

Methods: fifteen patients with hepatic cirrhosis (nine subjects - Child group B, and six subjects - Child group C) and nine control subjects were enrolled in the study. The main criteria taken into account to characterize the diagnosis of cirrhosis and its complications were the AST: ALT ratio, AST to platelet ratio index, Bonacini score, Meld score and Child classification.

Nutritional care in peptic ulcer.

Introduction: Peptic ulcer is a lesion of the mucosal lining of the upper gastrointestinal tract characterized by an imbalance between aggressive and protective factors of the mucosa, having H. pylori as the main etiologic factor. Dietotherapy is important in the prevention and treatment of this disease.

Effect of Uncaria tomentosa Extract on Apoptosis Triggered by Oxaliplatin Exposure on HT29 Cells.

Background/Aim. The use of herbal products as a supplement to minimize the effects of chemotherapy for cancer treatment requires further attention with respect to the activity and toxicity of chemotherapy. Uncaria tomentosa extract, which contains oxindole alkaloids, is one of these herbal products.

Brazilian nut consumption by healthy volunteers improves inflammatory parameters.

Objective: The aim of this study was to investigate the effect of a single dose of Brazil nuts on the inflammatory markers of healthy individuals.

Method: A randomized crossover study was conducted with 10 healthy individuals (mean age 24.7 ± 3.

Antioxidant effects of Phyllanthus niruri tea on healthy subjects.

Objective: To investigate the potential antioxidant effects of Phyllanthus niruri (P. niruri, Euphorbiaceae) tea on healthy subjects.

Methods: Five non-smoking, male healthy volunteers, 20 to 31 years old, were enrolled.

A single consumption of high amounts of the Brazil nuts improves lipid profile of healthy volunteers.

Background. This study investigates the effects of Brazil nut ingestion on serum lipid profile in healthy volunteers. Methods.

Factors associated with chronic gastritis in patients with presence and absence of Helicobacter pylori.

Background: Chronic gastritis is an inflammation of the stomach mucosa, which is considered its main etiological factor the Helicobacter pylori.

Aim: To observe the differences in patients with chronic gastritis as well as the presence and absence of H. pylori, to obtain a better understanding of the etiological factors, clinical, dietary and lifestyle habits and associated diseases.

Ascorbic acid oxidation of thiol groups from dithiotreitol is mediated by its conversion to dehydroascorbic acid.

The aim of the present study was to investigate whether the pro-oxidant effect of ascorbic acid towards thiol groups could be mediated by free radicals formed during its auto-oxidation and/or by a direct oxidation of -SH groups by its oxidized form (dehydroascorbic acid). This hypothesis was examined by measuring the rate of AA (ascorbic acid) oxidation in MOPS (3-morpholinepropanesulfonic acid buffer) and phosphate buffer (PB). Here we have used dithiothreitol (DTT) as model of vicinal thiol-containing enzymes, namely δ-aminolevulinate dehydratase.

[Analysis of the bariatric surgery impact in a population from the center area of Rio Grande do Sul State, Brazil, using the BAROS method].

Context: Due to metabolic alterations caused by overweight, the bariatric surgery has been a largely used procedure in order to propitiate long term weight loss and maintenance in a population with morbid obesity.

Objective: To analyze the impact of bariatric surgery in a population from the center area of Rio Grande do Sul State, Brazil, using the BAROS method.

Method: It was carried out a retrospective study with 32 patients from both sexes, aging between 19 and 44 years old who were patients from a private clinic at the city of Santa Maria, RS.

Diphenyl diselenide decreases serum levels of total cholesterol and tissue oxidative stress in cholesterol-fed rabbits.

Hypercholesterolaemia and oxidative stress are well-known risk factors in coronary artery diseases. Diphenyl diselenide is a synthetic organoselenium compound that has been shown to have in vitro and in vivo antioxidant properties. In this study, we investigated whether diphenyl diselenide could reduce the hypercholesterolaemia and diminish the tissue oxidative stress in cholesterol-fed rabbits.

A single high dose of ascorbic acid and iron is not correlated with oxidative stress in healthy volunteers.

Fe (II) is a potential prooxidant in vivo and can induce cellular oxidative stress. Ascorbic acid (AA) is a powerful physiological antioxidant and, in the presence of free Fe (II), can exhibit prooxidant effects in vitro. However, in vivo prooxidant effects of Fe (II) and AA have not yet been indisputably demonstrated.

Plasmatic vitamin C in nontreated hepatitis C patients is negatively associated with aspartate aminotransferase.

Objectives: To evaluate the possible relationship between aminotransferases levels and markers of oxidative stress in chronic hepatitis C patients.

Design And Methods: Patients without treatment for hepatitis were divided in to group I (15-39 U/L); group II (41-76 U/L) and group III (81-311 U/L) of activity alanine aminotransferase (ALT). Blood markers of oxidative stress [catalase (CAT), glutathione peroxidase (GPx), thiobarbituric acid-reactive species (TBARS), nonprotein and protein thiol (NP-SH and P-SH) groups and vitamin C] were determined.
