On the Relation Between SIM and IND-RoR Security Models for PAKEs with Forward Secrecy

Password-based Authenticated Key-Exchange (PAKE) protocols allow the establishment of secure communication entirely based on the knowledge of a shared password. Over the last two decades, we have witnessed the debut of a number of prominent security models for PAKE protocols, whose aim is to capture the desired security properties that such protocols must satisfy when executed in the presence of an active adversary. These models are usually classified into (i) indistinguishability-based (IND-based) or (ii) simulation-based (SIM-based). However, the relation between these two security notions is unclear and mentioned as a gap in the literature. In this work, we prove that SIM-BMP security from Boyko et al. (EUROCRYPT 2000) implies IND-RoR security from Abdalla et al. (PKC 2005) and that IND-RoR security is equivalent to a slightly modified version of SIM-BMP security. We also investigate whether IND-RoR security implies (unmodified) SIM-BMP security. The results obtained also hold when forward secrecy is incorporated into the security models in question

Recommandations Formalisées d’Experts de l’Association Française de Psychiatrie Biologique et Neuropsychopharmacologie sur le dépistage et prise en charge du trouble bipolaire : mise à jour 2014

International audienceAs part of a process to improve the quality of care, the French Society for Biological Psychiatry and Neuropsychopharmacology developed in 2010 formal consensus guidelines for the treatment of bipolar disorder. The evolution of therapeutic options available in France for the treatment of bipolar disorder has justified the update of this guideline. The purpose of this work was to provide an updated and ergonomic document to promote its use by clinicians. This update focuses on two of the six thematic previously published (acute treatment and long-term treatment). Aspects of the treatment of bipolar patients sparking debate and questions of clinicians (use of antidepressant, place of the bitherapy, interest of long-acting antipsychotics…) were also covered. Finally, we proposed graded recommendations taking into account specifically the risk-benefit balance of each molecule

Hypovitaminosis D and Its Associated Factors in North Algerian Postmenopausal Women: Results of a Cross-Sectional Study

Purpose. As the vitamin D status of Algerian postmenopausal women was poorly described, this cross-sectional study investigated the prevalence of low vitamin D status in a sample population. Secondarily, predictive factors of this hypovitaminosis D were explored. Methods. All the 336 selected women ≥ 45 years from Douera were interviewed to get anthropometric and lifestyle data, reproductive and medical history, medications, and calcium/vitamin D intakes. A blood sample was collected to measure 25-hydroxyvitamin D (25(OH)D) concentrations. Results. Approximately 86% of subjects had low vitamin D status (<20 ng/mL). Mean 25(OH)D level was 14.4 ± 5.3 ng/mL with a clear seasonal dynamic and a significant negative correlation with PTH levels (r  = −0.15, p=0.006). A multiple regression analysis using the 25(OH)D cutoff value of 17 ng/mL instead of the generally admitted level of 20 ng/mL was performed to increase statistical power. Other seasons than summer (OR 4.159 and 95% CI 2.456–7.043), obesity (≥30 kg/m2, OR 1.826, 95% CI 1.081–3.083), and veiling (OR 3.526, 95% CI 1.090–11.400) were significantly associated with 25(OH)D concentrations <17 ng/mL. Conclusions. In North Algeria, the abundant sunlight appears insufficient to fully offset hypovitaminosis D risk factors in postmenopausal women, especially obesity and veiling. It suggests the major need to increase vitamin D supplementation in this subpopulation

GOSPEL 3 prise en charge de la goutte par les médecins généralistes et rhumatologues libéraux en France au début du XXIe siècle. Comparaison aux recommandations EULAR 2006

National audienceIntroduction: En 2006, des recommandations de prise en charge de la goutte ont été élaborées par l’EUropean League Against Rheumatism (EULAR). Le but de ce travail était de les comparer à la prise en charge par des médecins libéraux.Méthode: Dans cette étude prospective multicentrique nationale en France, des omnipraticiens et des rhumatologues libéraux ont été tirés au sort en 2009. Chacun a inclus deux patients goutteux consécutifs qui ont été évalués à deux reprises : lors de la consultation initiale puis entre les 3 et 6 mois suivants ; les informations sur les modalités de prise en charge EULAR 2006 ont été recueillies de façon standardisée.Résultats: Sur un total de 1003 patients, 771 patients ont été évalués aux 2 temps. L’allopurinol était prescrit chez 75,1 % des patients. Lors de l’instauration de l’allopurinol (n = 44), seuls 43,2 % d’entre eux ont reçu une dose initiale de 100 mg/j. La prévention des accès par la colchicine a concerné 74,3 % des patients. Sur 522 patients pour lesquels l’allopurinol est en cours à la consultation initiale, seuls 34,5 % avaient une uricémie ≤ 360 μmol/L (dose moyenne : 173 mg/j). Une alimentation trop riche a été repérée chez 31,5 % des patients en surpoids ou obèses par les généralistes, et chez 19,7 % par les rhumatologues, suivie de conseils nutritionnels chez 45,8 %. La correction d’une consommation excessive d’alcool n’a été recommandée que dans 10 % des cas. Les diurétiques n’ont été interrompus que chez 7 patients sur 175 possibles. Conclusion: Des écarts aux recommandations EULAR 2006 ont été identifiés, posant la question de leur simplification et de leur implémentation dans la formation médicale initiale et continue
