Body composition variables as predictors of NAFLD by ultrasound in obese children and adolescents

Background: Nonalcoholic fatty liver disease (NAFLD) is a disorder associated with excessive fat accumulation, mainly in the intra-abdominal region. A simple technique to estimate abdominal fat in this region could be useful to assess the presence of NAFLD, in obese subjects who are more vulnerable to this disease. The aim of this cross-sectional study was to verify the reliability of waist circumference and body composition variables to identify the occurrence of NAFLD in obese children and adolescents.Methods: Sample was composed of 145 subjects, aged 11 to 17 years. Assessments of waist circumference (WC), trunk fat mass (TFM) and fat mass (FM) by dual-energy X-ray absorptiometry (DXA) and ultrasound for diagnosis of NAFLD and intra-abdominal adipose tissue (IAAT) were used. Correlation between variables was made by Spearman's coefficients; ROC curve parameters (sensitivity, specificity, area under curve) were used to assess the reliability of body composition variables to assess the presence of NAFLD. Statistical significance was set at 5%.Results: Significant correlations were observed between NAFLD and WC (p = 0.001), TFM (p = 0.002) and IAAT (p = 0.001). The higher values of area under the ROC curve were for WC (AUC = 0.720), TFM (AUC = 0.661) and IAAT (AUC = 0.741).Conclusions: Our findings indicated that TFM, IAAT and WC present high potential to identify NAFLD in obese children and adolescents.

Vertical transmission of hepatitis C virus: A tale of multiple outcomes

Globally, hepatitis C virus (HCV) infection affects approximately 130 million people and 3 million new infections occur annually. HCV is also recognized as an important cause of chronic liver disease in children. The absence of proofreading properties of the HCV RNA polymerase leads to a highly error prone replication process, allowing HCV to escape host immune response. The adaptive nature of HCV evolution dictates the outcome of the disease in many ways. Here, we investigated the molecular evolution of HCV in three unrelated children who acquired chronic HCV infection as a result of mother-to-child transmission, two of whom were also coinfected with HIV-1. The persistence of discrete HCV variants and their population structure were assessed using median joining network and Bayesian approaches. While patterns of viral evolution clearly differed between subjects, immune system dysfunction related to HIV coinfection or persistent HCV seronegativity stand as potential mechanisms to explain the lack of molecular evolution observed in these three cases. In contrast, treatment of HCV infection with PegIFN, which did not lead to sustained virologic responses in all 3 cases, was not associated with commensurate variations in the complexity of the variant spectrum. Finally, the differences in the degree of divergence suggest that the mode of transmission of the virus was not the main factor driving viral evolution. (C) 2013 Elsevier B. V. All rights reserved.

Consultas de enfermagem com pacientes em tratamento para hepatite C

Infection with hepatitis C virus (HCV) is a worldwide problem of public health and who estimates 2.5% to 4.9% of infection by this virus among the population. This means that there are 3.9 to 7.6 million people at risk of developing cirrhosis or liver cancer. In Brazil, 20% to 58% of patients with chronic liver disease have antibodies to HCV (anti-HCV). To characterize the profile of patients undergoing treatment for hepatitis C in the Ambulatory General HC-FMB/UNESP, identify aspects of the disease and the phases of nursing process addressed during consultation. Transverse and descriptive study involving 38 patients undergoing treatment for Hepatitis C in Ambulatory General Area (Viral Hepatitis) in the period from July to September 2010. The population consisted of 38 patients, most of the males with completed higher education level, Catholic, married and aged predominantly between 41 and 60 years. Among the drugs used, we find the use of antihypertensive, antidepressant / anxiolytic and antidiabetic / hypoglycemic. With respect to specific medications used to treat hepatitis C, we found the use mainly of alfapeguinterferona 2b + ribavirin. The drugs used were complementary erythropoietin and filgastrim. There was a predominance of fibrosis 2 (F2) and genotype 1 (G1). Regarding the means of contamination, it was stressed blood transfusion and injection drug use. The most frequent drug reactions were decreased appetite, weight loss and discouragement. : The Nursing Process is considered a valuable tool in caring for patients with hepatitis C, because it works as identifying aspects of lifestyle, needs and potential of these patients and allows the deployment of humanized care strategies aimed at reduction of health hazards and improving the quality of life of these patients

Lipidose hepática felina

Feline hepatic lipidosis or fatty liver disease is a cholestatic syndrome that affects domestic cats and is characterized by excess fat accumulation in the liver of cats. Symptoms commonly seen with this syndrome are anorexia, weight loss, lethargy, vomiting, jaundice, and occasionally behavioral or neurologic signs such as excessive drooling, blindness, coma, and seizures. The diagnosis is based on the patient history, clinical examination, complementary examination, and the definitive diagnosis is obtained by cytology and/or histopathology of hepatic tissue. In serum biochemistry, the main findings include increased serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate amino transferase (AST) and bilirubin. The gamma glutamyl transferase (GGT) is normal or slightly increased. The cornerstone of therapy is aggressive feeding to supply the cat full caloric requirements. Without aggressive nutritional support and intensive monitoring the fatty liver disease can be fatal

Anthropometric indicators predict metabolic syndrome diagnosis in maintenance hemodialysis patients

Obesity has been considered the key in metabolic syndrome (MetS) development, and fat accumulation may be responsible for the occurrence of metabolic abnormalities in hemodialysis patients. The use of gold-standard methods to evaluate obesity is limited, and anthropometric measures may be the simplest methods. However, no study has investigated the association between anthropometric indexes and MetS in these patients. Therefore, the aim was to determine which anthropometric indexes had the best association and prediction for MetS in patients undergoing hemodialysis. Cross-sectional study that included patients older than 18 years, undergoing hemodialysis for at least 3 months. Patients with liver disease and cancer or those receiving corticosteroids or antiretroviral therapy were excluded. Diagnostic criteria from Harmonizing Metabolic Syndrome were used for the diagnosis of MetS. Anthropometric indexes evaluated were body mass index (BMI); percent standard of triceps skinfold thickness and of middle arm muscle circumference; waist circumference (WC); sagittal abdominal diameter; neck circumference; waist-to-hip, waist-to-thigh, and waist-to-height ratios; sagittal index; conicity index; and body fat percentage. Ninety-eight patients were included, 54.1% male, and mean age was 57.8 ± 12.9 years. The prevalence of MetS was 74.5%. Individuals with MetS had increased accumulation of abdominal fat and general obesity. Waist-to-height ratio was the variable independently associated with MetS diagnosis (odds ratio, 1.21; 95% confidence interval, 1.09-1.34; P < .01) and that better predicts MetS, followed by WC and BMI (area under the curve of 0.840, 0.836, and 0.798, respectively, P < .01). Waist-to-height ratio was the best anthropometric predictor of MetS in maintenance hemodialysis patients.
