    International audienceLa tomodensitomĂ©trie Rx est utilisĂ©e pour suivre la saturation et le sĂ©chage des pierres utilisĂ©es dans la construction de certains monuments. Les mesures d'attĂ©nuation des rayons X sont interprĂ©tĂ©es pour dĂ©terminer la rĂ©partition des phases minĂ©rales qui composent le matĂ©riau ainsi que la rĂ©partition de la porositĂ©. Les essais de saturation ou de sĂ©chage effectuĂ©s sous tomodensitomĂ©trie Rx permettent de suivre les variations de saturation du rĂ©seau poreux au cours des essais. Les interfaces entre zones saturĂ©es en fluides et zones sĂšches localisent de possibles zones de prĂ©cipitation de sels, processus important dans le dĂ©gradation de pierres d’Ɠuvre

    Les politiques mondiales de production agricole se retrouvent aujourd’hui face Ă  des dĂ©fis majeurs : d’une part, nourrir une population mondiale de plus en plus urbanisĂ©e et appelĂ©e Ă  croĂźtre de prĂšs de 2 milliards d’ici 2050, et, d’autre part, rĂ©pondre aux enjeux majeurs du changement climatique et de l’érosion de la biodiversitĂ©. Ces dĂ©fis de production se heurtent Ă©galement Ă  une demande sociĂ©tale de plus en plus prĂ©gnante visant (i) la diminution des externalitĂ©s nĂ©gatives sur l’environne..

    A Multicenter Study to Assess a Systematic Screening of Occupational Exposures in Lung Cancer Patients

    Occupational lung cancer cases remain largely under-reported and under-compensated worldwide. In order to improve the detection and compensation of work-related lung cancers, we implemented a systematic screening of occupational exposures, combining a validated self-administered questionnaire to assess occupational exposures and a specialized occupational cancer consultation. After a pilot study, the present prospective, open-label, scale-up study aimed to assess this systematic screening of occupational exposures in lung cancer patients in five sites in France by associating university hospitals with cancer centers. Patients with lung cancer were sent a self-administered questionnaire to collect their job history and potential exposure to lung carcinogens. The questionnaire was assessed by a physician to determine if a specialized occupational cancer consultation was required. During the consultation, a physician assessed if the lung cancer was occupation-related and, if it was, delivered a medical certificate to claim for compensation. Patients were offered help from a social worker for the administrative procedure. Over 15 months, 1251 patients received the questionnaire and 462 returned it (37%). Among them, 176 patients (38.1%) were convened to the occupational cancer consultation and 150 patients attended the consultation. An exposure to occupational lung carcinogen was identified in 133 patients and a claim for compensation was judged possible for 90 patients. A medical certificate was delivered to 88 patients and 38 patients received compensation. Our national study demonstrated that a systematic screening of occupational exposures is feasible and will bring a significant contribution to improve the detection of occupational exposures in lung cancer patients

    To develop a multidisciplinary French reference that addresses initial pre- and in-hospital management of a mild traumatic brain injury patient. A panel of 22 experts was formed on request from the French Society of Emergency Medicine (SFMU) and the French Society of Anaesthesiology and Critical Care Medicine (SFAR). A policy of declaration and monitoring of links of interest was applied and respected throughout the process of producing the guidelines. Similarly, no funding was received from any company marketing a health product (drug or medical device). The expert panel had to respect and follow the GradeÂź (Grading of Recommendations Assessment, Development and Evaluation) methodology to evaluate the quality of the evidence on which the recommendations were based. Given the impossibility of obtaining a high level of evidence for most of the recommendations, it was decided to adopt a "Recommendations for Professional Practice" (RPP) format, rather than a Formalized Expert Recommendation (FER) format, and to formulate the recommendations using the terminology of the SFMU and SFAR Guidelines. Three fields were defined: 1) pre-hospital assessment, 2) emergency room management, and 3) emergency room discharge modalities. The group assessed 11 questions related to mild traumatic brain injury. Each question was formulated using a PICO (Patients Intervention Comparison Outcome) format. The experts' synthesis work and the application of the GRADEÂź method resulted in the formulation of 14 recommendations. After two rounds of rating, strong agreement was obtained for all recommendations. For one question, no recommendation could be made. There was strong agreement among the experts on important, transdisciplinary recommendations, the purpose of which is to improve management practices for patients with mild head injury
