It is quite frequent that people assume poor postures during the day and they make their bodies more susceptible to injuries. Considering this, prevention assumes a central role as it can avoid damage and pain in day-to-day life, but it is very poorly practiced in the majority of countries, even in the Western world. Moreover, diagnosis and assessments for postural abnormalities are demanded to few specialized centers, which usually perform anecdotal or subjective evaluations. In this paper, we propose an innovative model to face up to postural abnormalities starting from a two-stage approach that have been conceived and are being implemented by the KISS-Health Project. The idea consists of two units: a) the Mobile Diagnostic System, which is composed of both hardware and software components and it will permit a first assessment of human posture in order to identify people at risk; b) the Laboratory Diagnostic System, which will investigate more accurately the complete postural configuration of the subject going under exam. It is our goal to promote an integrated approach that, based on scientific and economical evidences, will reduce the costs related to postural abnormalities.","PeriodicalId":177948,"journal":{"name":"IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131661404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we for the first time present a combined real-time 3D Photoacoustic tomography (PAT) and electro-physiology (EEG) system for the study of neurovascular coupling in epilepsy, whose ability was demonstrated with a pentylenetetrazol (PTZ) induced generalized seizure model in rats. Two groups of experiments were carried out with different wavelengths to detect the changes of oxy-hemoglobin (HbO2) and deoxy-hemoglobin (Hbr) signals in the rat brain. We extracted the average PAT signals of the superior sagittal sinus (SSS), and compared them with the EEG signal. Results showed that the seizure process can be divided into three stages. A `dip' lasting for 1-2 minutes in the first stage and the following hyperfusion in the second stage were observed. The oxy-hemoglobin (HbO2) signal and the deoxy-hemoglobin (Hbr) signal were generally negatively correlated. Compared to other existing functional neuroimaging tools, the proposed method here enables reliable tracking of hemodynamic signal with both high spatial and temporal resolution in 3D, so it's more suitable for neurovascular coupling study of epilepsy.","PeriodicalId":177948,"journal":{"name":"IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI)","volume":"9 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131732029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This dependency requires the telemedicine system design to be resilient for ICT performance degradation or subsystem failures. Nevertheless, using telemedicine systems create a dependency between medical and technological concerns. We propose a layering technique that links medical and technological concerns by using a two-staged scenario based requirements elicitation method. This layering technique provides functional relations between technological variables (e.g. raw ECG signal) and their technological context (e.g. measurements conditions), clinical variables (e.g. heart rate), and clinical abstractions (e.g. physical exercise target heart rate) and the non-functional quality of data relations between the layers. We use a hierarchical ontology to specify these functional and nonfunctional relations, which enables the development of technological context and quality-aware telemedicine systems that are able to cope with technological disruptions whilst preserving patient safety.","PeriodicalId":177948,"journal":{"name":"IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115314099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This represents the potential of detecting finer and more subtle effects related to pathology and is thus very appealing. It remains however unclear whether or not the potential confound introduced by scanner-related variations will devalue the integrity of any result. Specifically, it is crucial to test whether or not the error introduced into brain morphometry descriptors by image properties variations across scanners can exceed the effect of the disease itself. Moreover, evaluating the influence of the scanner on age-related effects in measurements is essential in the context of developmental disorders such as Autism Spectrum Disorders. In this study, we investigated a data-set of anatomical MRI pooled form three different scanners, representing a total of 186 subjects, 97 patients suffering from ASD and 89 controls. We quantitatively assessed the effects of age, pathology and scanner factors on cortical thickness measurements.","PeriodicalId":177948,"journal":{"name":"IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113967502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the virtual PHR concept is introduced as an entity on the network consisted of (a) a non-healthcare component containing health and social information collected by either the patient or non-healthcare providers, (b) a medical device component containing health information transmitted from Internet connected medical devices and (c) a healthcare professional component containing information stored into various healthcare information systems. The PHR concept is based on the patient-centered model dictating that patients are the owners of their information. Hence, patients are empowered to authorize other subjects to access it that introduces specific security challenges which are further accentuated by the fact that diverse local security policies may need to be reconciled. The PHR authorization system proposed here is based on a combination of role-based and attribute-based access control (RABAC) and supports patient-specified authorization policies of various granularity levels subject to constraints imposed by the security policies of the various health and social care providers involved. To this end, an ontology of granular security concepts is built to aid in semantically matching diverse authorization requests and to enable semantic rule reasoning on whether a requested access should be permitted or denied.","PeriodicalId":177948,"journal":{"name":"IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131518152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
