Urban environment and health: a cross-sectional multiregional project based on population health surveys in Spain (DAS-EP project) - study protocol.

Introduction: The European Environment Agency estimates that 75% of the European population lives in cities. Despite the many advantages of city life, the risks and challenges to health arising from urbanisation need to be addressed in order to tackle the growing burden of disease and health inequalities in cities. This study, (DAS-EP project), aims to investigate the complex association between the urban environmental exposures (UrbEEs) and health.

Health literacy: association with socioeconomic determinants and the use of health services in Spain.

Background: Health literacy (HL) is the set of social and cognitive skills that determine person's level of motivation and the ability to access, understand and use information to promote and maintain good health. The aim of this study is to assess the level of health literacy, and to analyze its relationship with sociodemographic variables, state of health, and use of health services in the population aged 15 and over in the Valencian Community (Spain).

Methods: Cross-sectional study based on a sample of 5,485 subjects participating in the Health Survey of the Valencia Community.

Performance of Simple Fibrosis Scores in Nonobese Patients With Nonalcoholic Fatty Liver Disease.

Because only a minority of patients with nonalcoholic fatty liver disease (NAFLD) have advanced fibrosis and would eventually develop liver-related complications, current guidelines recommend initial assessment with noninvasive tests of fibrosis. Most previous studies focused on overweight and obese patients. Despite a strong association between obesity and NAFLD, 3%-30% of people with relatively normal body mass index (BMI) may still have NAFLD.

New sequential combinations of non-invasive fibrosis tests provide an accurate diagnosis of advanced fibrosis in NAFLD.

Background & Aims: Advanced liver fibrosis is an important diagnostic target in non-alcoholic fatty liver disease (NAFLD) as it defines the subgroup of patients with impaired prognosis. The non-invasive diagnosis of advanced fibrosis is currently limited by the suboptimal positive predictive value and the grey zone (representing indeterminate diagnosis) of fibrosis tests. Here, we aimed to determine the best combination of non-invasive tests for the diagnosis of advanced fibrosis in NAFLD.

Unified interpretation of liver stiffness measurement by M and XL probes in non-alcoholic fatty liver disease.

Objective: The latest model of vibration-controlled transient elastography (VCTE) automatically selects M or XL probe according to patients' body built. We aim to test the application of a unified interpretation of VCTE results with probes appropriate for the body mass index (BMI) and hypothesise that this approach is not affected by hepatic steatosis.

Design: We prospectively recruited 496 patients with non-alcoholic fatty liver disease who underwent VCTE by both M and XL probes within 1 week before liver biopsy.
