BACKGROUND Müllerian adenosarcoma (MA) is a rare neoplasm composed of benign epithelial and malignant stromal components. Its location in the cervix and the presence of heterologous elements are extremely infrequent (to our knowledge, only 14 more cases have been reported in the English literature). We describe another case of MA of the uterine cervix with(More)
—An approach to study the effects of single event upsets (SEU) by fault injection performed at system-level is presented. It is illustrated by results obtained on two different versions of a matrix multiplication algorithm, one standard and the second with fault tolerance capabilities. The final goal of this work is to validate fault tolerance techniques(More)
AIMS The role of high-intensity exercise and other emerging risk factors in lone atrial fibrillation (Ln-AF) epidemiology is still under debate. The aim of this study was to analyse the contribution of each of the emerging risk factors and the impact of physical activity dose in patients with Ln-AF. METHODS AND RESULTS Patients with Ln-AF and age- and(More)
Our objective was to identify individual- and school-level contextual factors related to adherence to the recommendations for physical activity in adolescents. The study used a representative sample of 15,902 students from 328 schools aged 11-18 years participating in the Spanish Health Behaviour in School-aged Children (HBSC) survey 2006. In addition to(More)
OBJECTIVES To investigate the relationship between the histopathologic effects of preoperative chemoradiotherapy in rectal cancer and the proteins, proliferating cell nuclear antigen (PCNA) and p53. METHODS Samples from 73 tumors were examined. The histopathologic effects observed in the resected specimens induced by preoperative chemoradiotherapy were(More)
OBJECTIVES Little is known about the dose-response relationship between physical activity and health benefits among young people. Our objective was to analyse the association between the frequency of undertaking moderate-to-vigorous physical activity (MVPA) and the self-reported health status of the adolescent population. DESIGN Cross-sectional study. (More)
BACKGROUND OSA increases atrial fibrillation (AF) risk and is associated with poor AF treatment outcomes. However, a causal association is not firmly established and the mechanisms involved are poorly understood. The aims of this work were to determine whether chronic obstructive sleep apnea (OSA) induces an atrial pro-arrhythmogenic substrate and to(More)
INTRODUCTION Atrial fibrillation (AF) is a recognized treatable cause of tachycardiomyopathy (TMP), with class IIb indication for catheter ablation (CA). The aim of this study is to analyze the prevalence, clinical characteristics and effect of CA in patients with TMP and to evaluate TMP as a prognostic factor for AF recurrence in these patients (TMP(More)
BACKGROUND The prevalence of genetic alterations is different in primary carcinomas from the proximal colon when compared with carcinomas from the distal colorectum. The objective of this work was to explore the existence of possible differences in the informative weight of the risk of tumor recurrence provided by p53 immunostaining depending on the(More)
Objective: Clinical Decision Support Systems normally resort to annotated signals for the automatic assessment of ECG signals. In this paper we put forward a new method for the assessment of normal/abnormal heart function from raw ECG signals (i.e. signals without annotation) based on shallow neural networks with pretraining. Methodology: this paper resorts(More)
