The renal resistive index: is it a misnomer?
2015
Progress in digital ultrasound technology and diffusion of Doppler ultrasound evaluation of the kidney enable a widespread non-invasive evaluation of renal haemodynamics. Initially most attention has been paid to the study of extraparenchymal renal arteries, mainly to detect renovascular disease. However, this approach has low reproducibility and accuracy. Therefore, interest has gradually moved towards the duplex evaluation of intrarenal anatomy, where the best and most reliable signals are obtained from the large segmental or interlobar arteries that run directly towards the transducer. Among the sonographic parameters used in the last decade, great emphasis has been placed on the intrare…
SNOMED on FHIR Transmission of clinical data with the Fast Healthcare Interoperability Resources protocol (HL7-FHIR) utilizing Systematized Nomenclat…
2019
Master's thesis Information- and communication technology IKT590 - University of Agder 2019 The exchange of information at the level of semantic interoperability needs some infor-mation model and clinical terminology work together. Electronic records of the patientmust include the terminologies in order to give the decision support to the practitionerwhen needed. Due to the lack of common standards for data structure and data sharingcreates the problem to interact and share information with different applications.Our main goal in this thesis is transferring the SNOMED-CT (Systematized Nomenclatureof Medicine Clinical Terms) terminologies using HL7 FHIR (Fast Healthcare Interoper-ability Res…
An Automatic Ontology-Based Approach to Support Logical Representation of Observable and Measurable Data for Healthy Lifestyle Management: Proof-of-C…
2020
Background Lifestyle diseases, because of adverse health behavior, are the foremost cause of death worldwide. An eCoach system may encourage individuals to lead a healthy lifestyle with early health risk prediction, personalized recommendation generation, and goal evaluation. Such an eCoach system needs to collect and transform distributed heterogenous health and wellness data into meaningful information to train an artificially intelligent health risk prediction model. However, it may produce a data compatibility dilemma. Our proposed eHealth ontology can increase interoperability between different heterogeneous networks, provide situation awareness, help in data integration, and discover…
Is the term 'Mediterranean diet' a misnomer?
2010
Published version of an article from the journal: Public Health Nutrition. Also available from Cambridge University Press: http://dx.doi.org/10.1017/s1368980010000480 OBJECTIVE: A greater adherence to what has been labelled the Mediterranean diet is associated with a significant improvement in health status. However, it is unclear what this diet really contains. The objective of the present study is to discuss the contents of the scientific Mediterranean diet. CONCLUSIONS: We argue that the evidence of the health-enhancing properties of the Mediterranean diet is not necessarily based on Mediterranean foods, and that we indeed do not have to eat Mediterranean foods to enjoy the health-promot…
HL7 FHIR with SNOMED-CT to Achieve Semantic and Structural Interoperability in Personal Health Data: A Proof-of-Concept Study
2022
Heterogeneity is a problem in storing and exchanging data in a digital health information system (HIS) following semantic and structural integrity. The existing literature shows different methods to overcome this problem. Fast healthcare interoperable resources (FHIR) as a structural standard may explain other information models, (e.g., personal, physiological, and behavioral data from heterogeneous sources, such as activity sensors, questionnaires, and interviews) with semantic vocabularies, (e.g., Systematized Nomenclature of Medicine—Clinical Terms (SNOMED-CT)) to connect personal health data to an electronic health record (EHR). We design and develop an intuitive health coaching (eCoach…

Within the quick nano-fabrication techniques evolution and the increasing needs in low space and energy opto-electronic functions on-chip integration, studies and control of electromagnetic resonances of sub-micrometric objects are crucial issues. One aim of this work was then to improve our knowledge of the light-matter interaction. To this end, optical near-field experiments and complementary numerical development of models have been performed to study electromagnetic resonances due to light-matter interaction in sub-micrometric resonators. As an introduction, the first part of the manuscript presents the main phenomena involved in near-field optical microscopy and the used SNOM operation…
SNOM signal near plasmonic nanostructures: an analogy with fluorescence decays channels
2008
International audience; Scanning Near-field Optical Microscope (SNOM) is based on local excitations of nanostructures deposited on a substrate (illumination mode). Ideally, the local source behaves like a dipolar emitter so that the SNOM signal is strongly similar to the fluorescence decay rates of an excited molecule that would be located at the SNOM tip position. We present here how the SNOM signal near plasmonic nanostructures can be used to analyze radiative and non-radiative contribution to the fluorescence decay rate.
A new tool for nanoscale X-ray absorption spectroscopy and element-specific SNOM microscopy.
2007
Abstract Investigations of complex nanostructured materials used in modern technologies require special experimental techniques able to provide information on the structure and electronic properties of materials with a spatial resolution down to the nanometer scale. We tried to address these needs through the combination of X-ray absorption spectroscopy (XAS) using synchrotron radiation microbeams with scanning near-field optical microscopy (SNOM) detection of the X-ray excited optical luminescence (XEOL) signal. The first results obtained with the prototype instrumentation installed at the European Synchrotron Radiation Facility (Grenoble, France) are presented. They illustrate the possibi…
