Our approach tries to recognize also concepts which are named with local terminology, with medical writing scripts, short words, abbreviations and even spelling mistakes. We consider a clinical terminology ontology (Snomed-CT), as a dictionary of concepts. In a first step we obtain an embedding model using word2vec methodology from a big corpus database of clinical reports. Word vectors are positioned in the vector space such that words that share common contexts in the corpus are located in close proximity to one another in the space, and so the geometrical similarity can be considered a measure of semantic relation. We have considered 615513 emergency clinical reports from the Hospital \"Rafael Mendez\" in Lorca, Murcia. In these reports there are a lot of local language of the emergency domain, medical writing scripts, short words, abbreviations and even spelling mistakes. With the model obtained we represent the words and sentences as vectors, and by applying cosine similarity we identify which concepts of the ontology are named in the text. Finally, we represent the clinical reports (EHR) like a bag of concepts, and use this representation to search similar documents. The paper illustrates 1) how we build the word2vec model from the free text clinical reports, 2) How we extend the embedding from words to sentences, and 3) how we use the cosine similarity to identify concepts. The experimentation, and expert human validation, shows that: a) the concepts named in the text with the ontology terminology are well recognized, and b) others concepts that are not named with the ontology terminology are also recognized, obtaining a high precision and recall measures.","PeriodicalId":74567,"journal":{"name":"Proceedings.

External Radiotherapy is the most common treatment used in the world. Radiotherapy Planning Systems (RTPS) is a software suite used for delineation of organs and calculation of irradiation doses and is essential to ensure the accuracy of oncologic treatment in clinics and hospitals. This works presents a type of RTPS, named SIPRAD, developed for public hospitals reality in Brazil with the assistance of the doctors. SIPRAD architecture uses a number of management and operational tools for all radiotherapy treatment process. One of the main contributions of this work is its interoperable infrastructure capable of communicating with all health systems and devices. Another contribution is a drawing tool, which is able to perform an automatic contour delineation in organs at risk and tumors volumes. Additionally also extends the use of tomography slices in grayscale images applied in three plans: axial, coronal and sagittal. SIPRAD automatic contour delineation saves up 75% of the time for drawings in three different types of regions body exams. Finally, SIPRAD was tested in a set of oncologic exams provided by the University of Sao Paulo Clinical Hospital (HCRP and HC-USP) in Brazil obtained from patients with different conditions of ethnology, ages, tumor severities and body regions.","PeriodicalId":74567,"journal":{"name":"Proceedings.

Today, studies of arrhythmogenesis and maintenance are largely being performed by creating simulations of a particular arrhythmia with high accuracy comparable to the results of clinical experiments. Atrial fibrillation (AF), the most common arrhythmia in the United States and many other parts of the world, is one of the major field where simulation and modeling is largely used. AF simulations not only assist in understanding its mechanisms but also help to develop, evaluate and improve the computer algorithms used in electrophysiology (EP) systems for ablation therapies. In this paper, we begin with a brief overeview of some common techniques used in simulations to simulate two major AF mechanisms - spiral waves (or rotors) and point (or focal) sources. We particularly focus on 2D simulations using Nygren et al.'s mathematical model of human atrial cell. Then, we elucidate an application of the developed AF simulation to an algorithm designed for localizing AF rotors for improving current AF ablation therapies. Our simulation methods and results, along with the other discussions presented in this paper is aimed to provide engineers and professionals with a working-knowledge of application-specific simulations of spirals and foci.","PeriodicalId":74567,"journal":{"name":"Proceedings.

Thefindings have been validated in the specific dataset usingstatistical analysis methods. Association rule mining shows an association between gastrooesophagealreflux and the medicines prescribed forhypertension and heart diseases, which agrees with findings inthe related literature. Another interesting finding, not yet beenreported in related studies is the association between heartdiseases, gastroesophageal reflux and insulin-dependentdiabetes mellitus for patients that have both hypertension andhypercholesterolemia. Apart from the medical findings, which must be subject offurther research we propose a methodology for the analysis ofdata collected from a continuous screening process of a groupof patients. With the use of data mining techniques we are ableto extract and formulate the potential research questions, which are then validated using statistical methods and can alsobe validated in larger population studies.","PeriodicalId":74567,"journal":{"name":"Proceedings.

Since there are no terms of miRNAs annotation in Gene Ontology (GO) nor a database with miRNA functional annotation, the direct computation of functional similarity between miRNAs cannot be done under an established standardized approach. However, a miRNA can be annotated with a set of information, such as if it acts as oncogene or as tumour suppressor, the organism that it belongs, its association with diseases, target genes, proteins and pathological events. This way, the similarity between two miRNAs can be inferred based, for example, in the relative position of their respective target genes in GO. In this study, we propose and evaluate CFSim, a method that uses GO and the disease ontology MeSH to compute miRNAs composed similarity by combining different information related to them. We validated CFSim by examining functional similarity values inferred intra and inter miRNA families, and the results showed that our method is efficient in sense that the functional similarity between miRNAs in the same family was higher compared to other miRNAs from distinct families. Furthermore, in comparison with existing methods for functional similarity, CFSim is more effective in distinguishing miRNA families.","PeriodicalId":74567,"journal":{"name":"Proceedings.

METHODS: Information was modeled using the methodology for developing archetypes proposed in the International Standardization Organization 13606 standard. RESULTS: The electronic document was implemented in a university hospital, and the information was divided into two sections, one containing maternal data and the other neonate(s) information. An Electronic Health Record extract in eXtensible Markup Language, containing structured clinical data, will constitute the vector of transmission system from hospital information to primary care units.
