Identifying temporal patterns in patient disease trajectories: a population-based study

The widespread use of electronic health record (EHR) datasets has facilitated the massive collection of patient health information, thereby enabling researchers to conduct large-scale studies of comorbidities. The term comorbidity can be defined as the co-occurrence of two or more diseases within the same individual. The factor of time has, typically, not been taken into account in most of the relevant works. However, by incorporating the time dimension into a comorbidity study more complex disease patterns and their temporal characteristics can be revealed. In this work, a large-scale temporal comorbidity study is performed on a local (Catalonian) health database. The disease-history vectors of individual patients are compared between each other in order to extract common disease trajectories (i.e. shared by at least 2 patients). By using statistical-significance tests on the common disease trajectories of length=2, significant pairwise disease associations are identified and their temporal directionality is assessed. Subsequently, a novel unsupervised clustering algorithm, based on the Dynamic Time Warping (DTW) technique, is applied on all extracted common disease trajectories (length>=2), in order to group them according to the temporal patterns that they share. It will be shown that DTW can successfully cluster the disease-trajectory signals under investigation, which consist of various time scales and durations, although they do not exhibit any obvious temporal alignment. In this manner, important key clusters can be identified with trajectories that share the same time-dependent characteristics. A time-dependent comorbidity analysis is expected to facilitate the early diagnosis of a disease and prevent any adverse outcomes, by permitting the prediction of the disease progression along time.

Tutorial at ECCB 2016 - DisGeNET: a discovery platform to support translational research on human diseases

Recent technological breakthroughs have produced an unprecedented increase in the amount of data on the genetic determinants of diseases. To unveil the molecular mechanisms that underlie diseases and to support drug discovery projects, it is necessary to place these data in the context of the current biomedical knowledge. Despite the large volume of information available, its analysis and interpretation are hindered because it is annotated using different criteria and vocabularies and fragmented across different resources. Furthermore, a large fraction of data on diseases is only available as free text in biomedical publications. To overcome these difficulties we have developed DisGeNET (Piñero et al, 2015), a discovery platform that contains information on human diseases and their genes. In this tutorial we will provide an overview of the main features of DisGeNET, and then introduce the suite of tools that the platform offers to support translational research.  The tutorial includes a hands-on session organized around case studies that will illustrate how to use these tools. Materials will be made available via the DisGeNET website. Target audience: the tutorial is aimed at a variety of audiences: bioinformaticians, systems biology users, biologists, and healthcare practitioners.

"Extracting biological data from the Science Literature"

Abstract: The scientific literature constitutes a rich and diverse source of information essential for any research line in life sciences. The volume of scientific publications is growing year by year generating a large accumulation of literature, due to the constant developments and advances in the biomedical domain. Text Mining (TM) emerges to address the need generated by the continuous growth of scientific literature in the biomedical domain. In this talk I will give an overview of TM and how it can help us to find relevant information from a large set of documents. I will present the BeFree System, a text mining tool developed as part of my PhD thesis and its application to different projects related to investigating the genetic basis of diseases, the therapeutic and undesired effects of drugs, and the effect of drugs in the environment.

DisGenet RDF&SPARQL: how to use + modeling challenges

Upcoming PhD course on Semantic Web technologies offered by SIB in Geneva. We are pleased to announce that a lecture on DisGeNET-RDF developed in the IBI group is included in the course "Using the Semantic Web for faster (Bio-)Research", Geneva 30 November till 3 December 2015. Accessing and using existing public data is a hassle, yet it is crucial for designing good experiments. This 4 day course, co-organized by SIB and CUSO/Staromics, will teach PhD students on how to use semantic web technologies for their own research. It includes an in-depth exploration of Semantic Web concepts such as RDF (data modelling), SPARQL (asking questions on your data), OWL (reasoning for deducing new facts about your data) The course will teach you how to use these technologies in your day to day research, as well as how you can share your data with the rest of the world.

"Uncovering disease mechanisms through network biology in the era of next generation sequencing"

Characterizing the behavior of disease genes in the context of biological networks has the potential to shed light on disease mechanisms, and produce new candidate disease genes and therapeutic targets. Previous studies addressing the network properties of disease genes have produced seemingly contradictory results. We have explored the causes of these seeming discrepancies and assessed the relationship between disease genes' network roles and their tolerance to deleterious germline variants in human populations leveraging on: different interactome resources, a comprehensive catalog of disease genes and exome variation data. We found that the most salient network features of disease genes are driven by cancer genes and that genes related to different types of diseases play network roles whose centrality is inversely correlated to their tolerance to likely deleterious germline mutations. This proved to be a network multiscale signature, including global, mesoscopic and local network centrality features. Cancer driver genes, the most sensitive to deleterious variants, occupy the most central positions, followed by dominant disease genes and then by recessive disease genes, which are tolerant to variants and isolated within their network modules.

DisGeNET: a discovery platform for translational bioinformatics (PRBB Computational Genomic Seminars)

In this talk I will present the DisGeNET Discovery Platform for the dynamical exploration and analysis of human diseases and their genes. The platform consists of a comprehensive knowledge base of over 400,000 gene-disease associations arising from both expert-curated databases and information extracted from the scientific literature using text mining, with special attention paid to the explicit provenance of the association. The DisGeNET platform provides a set of analysis tools designed to facilitate and foster the study of the molecular underpinning of human diseases. The talk will also illustrate the semantic knowledge representation of DisGeNET, and how to explore and analyze the data using different tools with special emphasis on harnessing the data using Semantic Web technologies.

New generation biomarkers based on mechanistic insight into disease

The impact of the genomic revolution in the field of medicine has been enormous. The concept of personalized medicine has evolved to precision medicine, which aims to find better ways of defining diseases by relating conventional clinical-pathological diagnostic criteria with state-of-the-art molecular profiling methodologies. Besides, a more precise diagnostic of the disease, based on the description of their molecular mechanisms would allow creating innovative diagnostic, prognostic, and therapeutic strategies precisely tailored to each patient's requirements. To achieve this, a deeper, systems-based understanding of these disease drivers is required. Here I will discuss how primary gene expression and gene variation data can be integrated and transformed into mechanism-based biomarkers containing higher-level information on disease mechanisms by means of relatively simple models of functional pathways.
