2Health-e-Child Establish Horizontal and Vertical integration of data, information and knowledge for Paediatrics Develop a grid-based biomedical information platform, supported by sophisticated and robust search, optimisation, and matching techniques for heterogeneous information, Build enabling tools and services that improve the quality of care and reduce its cost by increasing efficiency Integrated disease models exploiting all available information levels Database-guided decision support systems Large-scale, cross-modality information fusion and data mining for knowledge discovery Knowledge RepositoryPaediatrics A Knowledge Repository for Paediatrics Establish Horizontal and Vertical integration of data, information and knowledge for Paediatrics Develop a grid-based biomedical information platform, supported by sophisticated and robust search, optimisation, and matching techniques for heterogeneous information, Build enabling tools and services that improve the quality of care and reduce its cost by increasing efficiency Integrated disease models exploiting all available information levels Database-guided decision support systems Large-scale, cross-modality information fusion and data mining for knowledge discovery Knowledge RepositoryPaediatrics A Knowledge Repository for Paediatrics Cardiology Tetralogy of Fallot (ToF) Cardiomyopathy (HCM, DCM) Rheumatology Juvenile Idiopathic Arthritis (JIA) NeuroOncology Brain Tumors – Gliomas

3Health-e-Child The Grid from supercomputers to grid computing World is moving from supercomputers to grid computing that for a fraction of the cost are able to deliver the same services… Several regular computers + Powerful + Cheap + DeCentralized + UnLimited Scalability One big computer + Powerful - Expensive - Centralized - Limited Scalability SuperComputing Grid Computing Healthgrid +

4Health-e-Child  Three peadiatric hospitals  Gaslini, Genoa, Italy  GOSH, London, UK  Necker, Paris, France  OPBG, Rome, Italy  Strong interdisciplinary team across  Countries and languages  Technical and clinical fields  Research on three peadiatric disease areas:  Arthritis  Cardiac Disorders  Brain Tumours Health-e-Child Europe-wide Information Platform for Pediatrics

5Health-e-Child Research Focus in Rheumatology WristHip 163 patients enrolled (Target – 300) Improve current classification of JIA subtypes Identify homogeneous groups of clinical features Find early predictors of poor outcome Identify sensitive markers of joint damage progression Develop MRI and US paediatric scoring system Joint space width varies with age – studies performed on adult are not applicable on children. Robust Information Fusion Pattern discovery in multimodal data, correlation between genomic, clinical and image data Rely on the collaboration with PRINTO: Pediatric Rheumatology INternational Trials Organization

6Health-e-Child Research Focus in Cardiology Concentrating on Right Ventricular Overload and Cardiomyopathies Computational electromechanical models of the heart RVO monitoring and decision support based on similar cases – similarity search on complex, multimodal data Decision Support based on semi-automatic feature extraction from cardiac MR Health-e-Child CaseReasoner Visualizing integrated biomedical data for patient cohorts using treemaps and neighborhood graphs 257(RVO)+39(CMP) patients enrolled (Target – 300) Short AxisLong Axis

7Health-e-Child Research Focus in Neuro-oncology: Glioma growth model: Interpolating growth between two time instances Using proliferation and diffusion of tumor cells Including high speed of tumor invasion in white vs. grey matter Knowledge Discovery, Finding Prognostic Markers: Classification of low vs. high grade Sub-typing of pilocytic astrocytomas (e.g. regarding tumour site, age) Regression analysis of factors (clinical, imaging, genetics) that affect treatment outcome Prediction of prognosis (survival rate and quality of life) 49 Studies Collected (Target – 77)
