Reliability of Drug-Drug Interaction Measurement on Real-Word Data: The ReMIAMes Project.

The ReMIAMes project proposes a methodological framework to provide a reliable and reproducible measurement of the frequency of drug-drug interactions (DDI) when performed on real-world data. This framework relies on (i) a fine-grained and contextualized definition of DDIs, (ii) a shared minimum information model to select the appropriate data for the correct interpretation of potential DDIs, (iii) an ontology-based inference module able to handle missing data to classify prescription lines with potential DDIs, (iv) a report generator giving the value of the measurement and explanations when potential false positive are detected due to a lack of available data. All the tools developed are intended to be publicly shared under open license.

Increased Collagen Turnover Is a Feature of Fibromuscular Dysplasia and Associated With Hypertrophic Radial Remodeling: A Pilot, Urine Proteomic Study.

Fibromuscular dysplasia (FMD), a nonatherosclerotic, noninflammatory disease of medium-sized arteries, is an underdiagnosed disease. We investigated the urinary proteome and developed a classifier for discrimination of FMD from healthy controls and other diseases. We further hypothesized that urinary proteomics biomarkers may be associated with alterations in medium-sized, but not large artery geometry and mechanics.

Sociodemographic and Clinical Characteristics of Vapers Using E-Cigarettes Exclusively: The French Vapoquid Study.

Electronic cigarettes are increasingly being used as smoking cessation aids. Most studies assess the dual use of e-cigarettes and traditional cigarettes, but there remains a paucity of literature concerning individuals who use e-cigarettes exclusively. : The aim of this study is to examine the sociodemographic and clinical characteristics of exclusive e-cigarette users, and consider their willingness to quit e-cigarette use.

Pregnancy-Related Complications in Patients With Fibromuscular Dysplasia: A Report From the European/International Fibromuscular Dysplasia Registry.

Current literature suggests a higher risk of pregnancy-related complications in patients with renal fibromuscular dysplasia (FMD). The aim of our study was to assess the nature and prevalence of pregnancy-related complications in patients subsequently diagnosed with FMD. A call for participation was sent to centers contributing to the European/International FMD Registry.

Prevalence and characteristics of renal artery fibromuscular dysplasia in hypertensive women below 50 years old.

Background: Renal fibromuscular dysplasia (FMD) is typically diagnosed in young hypertensive women. The 2014 European FMD Consensus recommended screening in all hypertensive women <30 yo. However, the prevalence of renal FMD in young/middle-aged hypertensive women remains unclear.

[Fibromuscular dysplasia and hypertension : beyond renal arteries].

Fibromuscular dysplasia (FMD) is a disease associated with abnormalities of the arterial wall of medium-sized arteries. These abnormalities can lead to stenosis or less frequently to dissections or aneurysms. FMD is probably more frequent than initially thought.

Building a Semantic Interoperability Framework for Care and Research in Fibromuscular Dysplasia.

Unlabelled: Identifying patients with Fibromuscular Dysplasia (FMD) at the international level will have considerable value for understanding the epidemiology, clinical manifestations and susceptible genes in this arterial disease, but also for identifying eligible patients in clinical trials or cohorts. We present a two-step methodology to create a general semantic interoperability framework allowing access and comparison of distributed data over various nations, languages, formats and databases.

Methods: The first step is to develop a pivot multidimensional model based on a core dataset to harmonize existing heterogeneous data sources.

A "pivot" Model to set up Large Scale Rare Diseases Information Systems: Application to the Fibromuscular Dysplasia Registry.

The SIR-FMD project is a partnership between the Department of Genetics and Reference Centre for Rare Vascular Diseases at the Georges Pompidou European Hospital in Paris and the Medical Informatics and Knowledge Engineering Laboratory of Inserm. Its aim is to use an ontological approach to implement an information system for the French Fibromuscular Dysplasia Registry. The existing data was dispersed in numerous databases, which had been created independently.

ADVISE: First Results of a European Interoperative Information System Network Developed for the ADenoVirus Initiative Study in Epidemiology.

Adenoviral conjunctivitis is extremely contagious, causes a form of conjunctivitis. Therefore, it is important to identify patients who suffer from adenoviral conjunctivitis, as early as possible, in order to contain the disease. We present the 6 independent but interoperable platforms developed for the purpose of a large European epidemiologic study (ADVISE), which has been implemented independently in France, Germany, Spain, Italy and the UK.

A new approach for cleansing geographical dataset using Levenshtein distance, prior knowledge and contextual information.

Epidemiological studies are necessary to take public health decisions. Their relevance depends on the quality of data. Doctors in continuous care collect a big amount of data that can be used for epidemiological purpose, but spatial data may be dirty; based on city names, the localization is imprecise, even more if it is misspelled.

Suspected community-acquired pneumonia in an ambulatory setting (CAPA): a French prospective observational cohort study in general practice.

Background: Few studies have addressed the pragmatic management of ambulatory patients with suspected community-acquired pneumonia (CAP) using a precise description of the disease with or without chest X-ray (X-ray) evidence.

Aims: To describe the characteristics, clinical findings, additional investigations and disease progression in patients with suspected CAP managed by French General Practitioners (GPs).

Methods: The patients included were older than 18 years, with signs or symptoms suggestive of CAP associated with recent-onset unilateral crackles on auscultation or a new opacity on X-ray.

Venous thromboembolism prophylaxis in patients undergoing abdominal or pelvic surgery for cancer--a real-world, prospective, observational French study: PRéOBS.

Introduction: Data on the epidemiology and prevention of venous thromboembolism in patients undergoing abdominal or pelvic cancer surgery in real practice are limited. The primary objective of this observational study was to describe the thromboprophylactic strategy implemented in routine practice. The main secondary objective was to assess the incidence of outcomes.

CEMARA an information system for rare diseases.

Rare diseases cover a group of conditions characterized by a low prevalence, affecting less than 1 in 2,000 people; 5000 to 7000 rare diseases have been currently identified in Europe. Most diseases do not have any curative treatment. They represent thus an important public health concern.

Dynamical modeling of viral spread in spatially distributed populations: stochastic origins of oscillations and density dependence.

In order to understand the spatio-temporal structure of epidemics beyond that permitted with classical SIR (susceptible-infective-recovered)-type models, a new mathematical model for the spread of a viral disease in a population of spatially distributed hosts is described. The positions of the hosts are randomly generated in a rectangular habitat. Encounters between any pair of individuals are according to a Poisson process with a mean rate that declines exponentially as the distance between them increases.
