<em>Grid</em> poblacional 2011 para España. Evaluación metodológica de diversas posibilidades de elaboración

2017

Este trabajo presenta una evaluación, desde el punto de vista del usuario, de la malla regular (grid) de población, con resolución de 1 km2 , que el Instituto Nacional de Estadística (INE) ha hecho pública a partir de los resultados del Censo de Población y Viviendas 2011. Esta forma de difusión de resultados resulta muy novedosa y ofrece un gran valor analítico. Por primera vez esta información sobre la distribución espacial de la población se ha generado desde abajo (bottom-up) para el conjunto de España, es decir, a partir del conocimiento de las coordenadas de cada hogar, considerando como tales las del edificio donde reside. La disponibilidad de otra grid con idéntica resolución, elabo…

HLA antigens in ulcerative colitis: a study in the Sicilian population

2008

HLA antigens were investigated in 41 Sicilian patients with ulcerative colitis and in 151 healthy controls. Frequencies of HLA-B5 and DR2 were increased in the group of patients with ulcerative colitis whereas the DR3 antigen frequency was decreased. However the corrected p values were not significant. Thus, present results indicate that in ulcerative colitis HLA linked genetic factors play a marginal role, if any.

Incidence, severity and orthodontic treatment difficulty index of impacted canines in Saudi population

2018

Background The objective of this study was to assess the incidence, severity and orthodontic treatment difficulty of impacted maxillary canines in Saudi population. Material and methods This retrospective study included an investigation of panoramic radiographs for patients attended College of Dentistry, Jazan University, Saudi Arabia. The incidence of canine impaction and orthodontic treatment difficulty index of maxillary canine impaction was assessed based on; (1) patient age, (2) vertical position, (3) buccolingual position, (4) horizontal position, (5) incisors alignment, (6) canine space, (7) midline coincidence, (8) rotation of impacted tooth. Statistical analyses were calculated by …

Symptoms of depersonalization/derealization are independent risk factors for the development or persistence of psychological distress in the general …

2016

Abstract Background Symptoms of depersonalization (DP) and derealization (DR) have a high prevalence in patient and community samples. Previous studies suggested that DP/DR symptoms might represent a marker of disease severity and poor prognosis. However, population-based studies investigating the impact of DP/DR symptoms on the course of depression and anxiety are sparse. Therefore, we aimed to analyze whether symptoms of DP/DR are longitudinally associated with the persistence or incidence of elevated symptoms of depression/anxiety. Methods We analyzed observational data from a sample of 13.182 participants of the Gutenberg Health Study. The outcomes were elevated symptoms of depression/a…

P046 Occupational exposures and gastric cancer risk in the MCC-spain case-control study

2016

Objective To explore the relationship between gastric cancer (GC) and occupational exposures. Methods A total of 382 incident GC cases and 2,846 randomly selected population controls with occupational information were included from the MCC-Spain study, a population-based multicase-control study. Occupation was coded according to the Spanish National Classification of Occupations 1994. Occupational exposures were assessed by the MatEmEsp Job Exposure Matrix. ORs and their 95% confidence intervals (CI) were estimated by unconditional logistic regression adjusting for matching variables and education. Results In men, a statistically significant increased risk of GC, was found for ‘Employed ski…

Data Analysis of Epidemiological Studies

2010

Epidemiology is used to describe the distribution of diseases in the population and to analyze the causes of these diseases. One important objective is to identify risk factors and to quantify their significance. A risk factor can influence the probability that a specific disease develops. Risk factors include: Environmental influences (for example, exposure to radon) Predisposition (for example, genes), or Behavioral characteristics (for example, hormone intake). Epidemiological research employs various different types of study (1–3), depending on the question asked. The most important are Cohort studies Case-control studies, and Cross-sectional studies In cohort studies, persons exposed t…

SAT0390 Microrna Expression Profile in Fibromyalgia Patients: A Pilot Matched Case Control Study

2013

Background Fibromyalgia (FM) is a clinical syndrome characterized by musculoskeletal pain and tenderness. Diagnosis is mainly based on exclusion of other resembling diseases since validated biological tests are still lacking. Identification of disease-related markers will enable clinicians to effectively diagnose FM, follow the progress of the disease, monitor the effects of therapeutic approaches and probably develop preventive programs. MicroRNAs (miRNAs) are pieces of 18-25 nucleotides capable of regulating gene expression. Changes in their expression levels have been linked to environmental responses as well as to pathological processes. Their recent association to some other chronic di…

Oxidative stress, endothelial biomarkers and non-invasive vascular function in the general population in health and disease

2013

2018

Summary Background Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030. To fully deliver on the SDG aim of "leaving no one behind", it is increasingly important to examine the health-related SDGs beyond national-level estimates. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017), we measured progress on 41 of 52 health-related SDG indicators and estimated the health-related SDG index for 195 countries and territories for the period 1990–2017, projected indicators to 2030, and analysed global attainment.
