Protective effect of long-chain polyunsaturated fatty acids on hepatorenal syndrome in rats.

Background: Hepatorenal syndrome (HRS) is the most prevalent form of acute kidney injury in cirrhotic patients. It is characterized by reduced renal blood flow and represents the most severe complication in cirrhotic patients with advanced disease. Previous research has indicated that antioxidants can delay the onset of a hyperdynamic circulatory state in cirrhosis and improve renal function in HRS patients.

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.

Role of the phase angle in the prognosis of the cirrhotic patient: 15 years of follow-up.

Background: In 2019, cirrhosis accounted for 2.4% of global deaths. The projection for 2030 is an increase in this index.

Relationship between phase angle, steatosis, and liver fibrosis in patients coinfected with human immunodeficiency virus/hepatitis C virus.

Background: Malnutrition, lipodystrophy, and dyslipidemia are prevalent characteristics in patients with human immunodeficiency virus (HIV) infection with or without previous treatment. Such a clinical condition can lead to the hypothesis of the presence of hepatic steatosis with possible progression to fibrosis and the risk of hepatocellular carcinoma. Notably, a low phase angle (PA), evaluated by bioelectrical impedance analysis (BIA), is an independent prognostic marker of clinical progression and survival in HIV-infected patients.

Melatonin restores zinc levels, activates the Keap1/Nrf2 pathway, and modulates endoplasmic reticular stress and HSP in rats with chronic hepatotoxicity.

Background: Melatonin (MLT) is a potent antioxidant molecule that is shown to have a beneficial effect in various pathological situations, due to its action against free radicals.

Aim: To evaluate the effect of MLT on carbon tetrachloride (CCl) induced liver injury in rats in terms of oxidative stress, reticular stress, and cell damage.

Methods: Twenty male Wistar rats (230-250 g) were divided into four groups: Control rats, rats treated with MLT alone, rats treated with CCl alone, and rats treated with CCl plus MLT.

EVALUATION OF REST ENERGY EXPENDITURE IN PATIENTS WITH NON ALCOHOLIC FATTY LIVER DISEASE.

Background: Non-alcoholic fatty liver disease (NAFLD) is currently considered a global public health problem, with changes in lifestyle being the effective way to treat the disease. To date, there is no recommended standard of assessment to determine the resting energy expenditure (REE) of patients with NAFLD, so that dietary therapy can be properly guided.

Objective: To evaluate the REE of patients with NAFLD through indirect calorimetry and compare with different predictive formulas of REE and with REE by electrical bioimpedance analysis (BIA).

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.

Phase angle and non-alcoholic fatty liver disease before and after bariatric surgery.

Background: Obesity is a global health problem that is continuing to increase in the young population. In Brazil, the frequency of obesity in 2018 was 19.8%.

Pediatric enteral nutrition therapy for burn victims: when should it be initiated?

Objective: To review the scientific evidence regarding the initiation of enteral nutrition in the pediatric burn population.

Methods: This study was a systematic review and meta-analysis of randomized clinical trials comparing early enteral nutrition and late enteral nutrition in individuals aged 1 month to 18 years with burns. The MEDLINE/PubMed, Embase and Cochrane Library databases were searched using the terms "burns", "fires", "child nutrition disorders", "nutritional support" and related terms.

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.

THE CORRELATION OF NECK CIRCUMFERENCE AND INSULIN RESISTANCE IN NAFLD PATIENTS.

Background: Insulin resistance, especially that induced by obesity, plays a central role in the development of non-alcoholic fatty liver disease. Although the evaluation of overweight patients is important, the nutritional assessment tools used in clinical practice have limitations. Neck circumference (NC), from this, becomes a viable and low-cost alternative, which seems to be related to the accumulation of fat in the hepatic tissue.

Liver transplantation and alcoholic liver disease: History, controversies, and considerations.

Alcohol consumption accounts for 3.8% of annual global mortality worldwide, and the majority of these deaths are due to alcoholic liver disease (ALD), mainly alcoholic cirrhosis. ALD is one of the most common indications for liver transplantation (LT).

Nutritional evaluation in cirrhosis: Emphasis on the phase angle.

Protein-calorie malnutrition (PCM) is a common condition in cirrhotic patients, leading to a worse prognosis, complications, poor quality of life and lower survival rates. Among ways of assessing nutritional status, there are anthropometric methods such as the evaluation of the triceps skinfold, the arm circumference, the arm muscle circumference and the body mass index, and non-anthropometric methods such as the subjective global assessment, the handgrip strength of non-dominant hand, and the bioelectrical impedance analysis (BIA). PCM is frequently under-diagnosed in clinical settings in patients with cirrhosis due to the limitations of nutritional evaluation methods in this population.

ALTERATION OF TASTE BUDS IN EXPERIMENTAL CIRRHOSIS. Is there correlation with human hypogeusia?

Background: The inherent complications of cirrhosis include protein-calorie malnutrition and micronutrient deficiencies.Changes in taste are detrimental to the nutritional status, and the mechanism to explain these changes is not well documented in the cirrhotic patients.

Objective: To evaluate the taste buds of cirrhotic rats.

Introduction: Studies on infant dietary intake do not generally focus on the types of liquids consumed. Objective: To document by age and breastfeeding status, the types of liquids present in the diet of Mexican children under 1 year of age (< 1 y) who participated in the National Health and Nutrition Survey 2012 (ENSANUT-2012). Methods: Analysis of the infant < 1 y feeding practices from the ENSANUT-2012 survey in non-breastfed (non-BF) and breastfed (BF) infants by status quo for the consumption of liquids grouped in: water, formula, fortified LICONSA milk, nutritive liquids (NL; thin cereal-based gruel with water or milk and coffee with milk) and non-nutritive liquids (non-NL) as sugared water, water-based drinks, tea, beans or chicken broth, aguamieland coffee.

LIPID PROFILE OF CIRRHOTIC PATIENTS AND ITS ASSOCIATION WITH PROGNOSTIC SCORES: a cross-sectional study.

Background: In cirrhosis the production of cholesterol and lipoproteins is altered.

Objective: Evaluate the lipid profile by measuring total cholesterol, very low-density lipoprotein, low-density lipoprotein, high-density lipoprotein and triglyceride levels in patients with cirrhosis caused by alcoholism and/or hepatitis C virus infection and determine its association with Child-Pugh and MELD scores.

Methods: Cross-sectional retrospective study of patients treated at the outpatient clinic in Porto Alegre, Brazil, from 2006 to 2010.

Nutritional assessment in patients with cirrhosis.

Context: Malnutrition in cirrhotic patients with end-stage disease is common, and the degree of nutritional debilitation can play an important role in the pathogenesis of complications and cause a negative impact on prognosis. However, it involves difficulties and controversies regarding the identification of the best nutritional assessment method.

Objective: To identify a method that provides a safe and effective nutritional diagnosis.
