Averbuch, P.

Cette série d'articles est une revue de résultats expérimentaux sur différents "fluides" moléculaires, dans lesquels la cohésion est due à des forces de Van der Waals et à des liaisons hydrogène, l'eau étant un de ces fluides. Ces résultats sont présentés de façon à justifier expérimentalement un modèle original, non extensif, des propriétés de ces fluides, et l'ensemble se présente sous la forme de trois articles décrivant le modèle, suivis chacun par un article le comparant aux résultats expérimentaux publiés par de nombreux auteurs. Le caractère non extensif des propriétés physiques des fluides est choquant, contraire à beaucoup d'idées établies, il semble n'avoir en sa faveur qu'un argument, la comparaison avec un nombre de résultats expérimentaux assez grand pour que l'effet du hasard soit difficilement soupçonnable. En particulier, les écarts entre des résultats de mesures faits par des auteurs différents dans des conditions différentes sont expliqués, le sérieux et la compétence des différents expérimentateurs ne sont plus mis en doute : mais l'interprétation de ces résultats avec un modèle extensif non adapté est seule mise en cause. Les modèles extensifs étant utilisés systématiquement, au delà des expériences de physiciens, dans les calculs d'ingénieurs, et dans la modélisation d'appareils qui fonctionnent et de phénomènes naturels observés par tout le monde, il fallait expliquer pourquoi on pouvait renoncer à l'extensivité. Les raisons du succès pratique des modèles extensifs sont données, d'abord dans le cas des nématiques, puis dans celui des liquides ordinaires, et c'est ce qui rend l'ensemble cohérent, tant avec les mesures physiques fines qu'avec les observations quotidiennes. Il n'en reste pas moins que si l'interprétation donnée dans cette série d'articles est généralisable, une justification théorique du modèle utilisé devient nécessaire. Pour ce qui est des propriétés d'équilibre, une séparation de l'énergie libre en énergie libre de volume et en énergie libre de surface devrait donner les mêmes résultats ; par contre les choses deviennent troublantes dès que l'on passe aux coefficients de transport, c'est-à-dire à l'aspect macroscopique de la dynamique moléculaire. Il y a là un écart notable avec les conceptions courantes, ce qui rend très surprenante la lecture de ces articles. On peut mentionner la liste des problèmes théoriques posés par la description phénoménologique qui est celle de cette série d'articles : la généralisation de lois d'échelle en dehors de zones critiques n'est pas absolument nouvelle, par contre la simplicité des lois reliant l'exposant v à la température pose problème ; le sens des temps de relaxation utilisés est sans doute également à préciser. Enfin les modes considérés semblent n'intervenir dans les propriétés thermodynamiques que par un facteur par mode, comme si seulement l'énergie potentielle devait intervenir, les termes cinétiques ne participant pas vraiment aux transitions de phase. Tout cela pose donc problème, et l'on peut se demander si un pareil modèle peut être compatible avec tout ce qui est connu par ailleurs en physique statistique. Mais s'il rend bien compte de beaucoup de résultats expérimentaux, ce sont ces derniers qui seraient en difficulté avec la mécanique statistique. Il a donc semblé préférable de publier le modèle, sa justification expérimentale et de poser quelques problèmes, tant aux théoriciens, qui pourraient expliquer pourquoi un tel modèle rend compte de résultats observés, qu'aux expérimentateurs, qui pourraient reprendre certaines mesures, et délimiter le caractère plus ou moins général du modèle.

Le management des projets scientifiques

Perrier, Françoise

We describe in this paper a new approach for the management of scientific projects. This approach is the result of a long reflexion carried out within the MQDP (Methodology and Quality in the Project Development) group of INSU-CNRS, and continued with Guy Serra. Our reflexion was initiated with the study of the so-called `North-American Paradigm' which was, initially considered as the only relevant management model. Through our active participation in several astrophysical projects we realized that this model could not be applied to our laboratories without major modifications. Therefore, step-by-step, we have constructed our own methodology, using to the fullest human potential resources existing in our research field, their habits and skills. We have also participated in various working groups in industrial and scientific organisms for the benefits of CNRS. The management model presented here is based on a systemic and complex approach. This approach lets us describe the multiple aspects of a scientific project specially taking into account the human dimension. The project system model includes three major interconnected systems, immersed within an influencing and influenced environment: the `System to be Realized' which defines scientific and technical tasks leading to the scientific goals, the `Realizing System' which describes procedures, processes and organization, and the `Actors' System' which implements and boosts all the processes. Each one exists only through a series of successive models, elaborated at predefined dates of the project called `key-points'. These systems evolve with time and under often-unpredictable circumstances and the models have to take it into account. At these key-points, each model is compared to reality and the difference between the predicted and realized tasks is evaluated in order to define the data for the next model. This model can be applied to any kind of projects.

Bourque, Claude Julie

Le champ de la recherche scientifique et de la formation a la recherche est traverse depuis quelques dizaines d'annees par plusieurs courants et discours associes au changement, mais peu de travaux empiriques permettent de comprendre ce qui change concretement. C'est la contribution originale de cette these au champ de l'education, plus specifiquement a l'etude sociologique de l'enseignement superieur ou sont concentrees les activites liees a la triade thematique du programme doctoral dans lequel elle a ete produite : recherche, formation et pratique. L'enquete-terrain a ete realisee en 2009 et 2010 aupres de 808 repondants affilies a 60 etablissements au Quebec et a produit un vaste materiau de nature mixte (donnees quantitatives et qualitatives). Un portrait de la nebuleuse biotechnologique qui touche les secteurs des sciences de la sante, des sciences naturelles et du genie a ete realise. Ce domaine concerne des dizaines de disciplines et se revele de nature transdisciplinaire, mais les pratiques n'y sont pas davantage marquees par le changement que celles d'autres domaines connexes. Les dynamiques sociales ont fait l'objet d'analyses comparatives dans quatre contextes: le choix des programmes, des objets et des methodes, le financement, la diffusion et la planification de la carriere. Les resultats indiquent que les echanges entre les agents traditionnellement situes au coeur des activites de recherche dominent ces dynamiques dans tous les contextes etudies. L'etude des representations au fondement des pratiques a revele l'existence de trois ecoles de pensee qui coexistent dans le champ scientifique: academique, pragmatique et economiste. Ces ecoles permettent de categoriser les agents en fonction des zones de fractures qui marquent leurs oppositions tout en identifiant ce qu'ils ont en commun. Les representations et les pratiques liees a la formation temoignent d'un habitus plutot homogene, alors que les contradictions semblent plus souvent ancrees dans des

Dedifferentiated liposarcoma represents a form of liposarcoma composed of a non-lipogenic sarcoma associated with well-differentiated liposarcoma. The prognostic significance of histological grading of the dedifferentiated component remains to be elucidated due to vague grading criteria employed in previous studies. Molecular markers of tumor behavior, including amplification levels of murine double minute-2 (MDM2) and cyclin-dependent kinase-4 (CDK4) genes, have been explored in a limited number of cases. Here we investigate whether 'Fédération Nationale des Centres de Lutte Contre le Cancer' (FNCLCC) grade and MDM2 gene amplification levels have prognostic value in dedifferentiated liposarcoma in terms of local recurrence and disease-specific survival. Fifty cases were retrieved, reviewed and FNCLCC grade was scored for the dedifferentiated component. Testing for MDM2 gene amplification was performed by fluorescence in situ hybridization. Amplification was categorized as high level (≥20 copies) and as low level (<20 copies). Follow-up data was obtained through chart review. Log-rank test and Cox proportional hazard models were used to determine the effect of grade and level of MDM2 amplification on outcomes. Our series includes 50 patients (male n=28, female n=22) with an average age of 63 years (range, 28-88) and a median follow-up of 28 months (range, 2-120). Tumors were graded as grade 1 (6%), grade 2 (58%), and grade 3 (36%). When adjusted for age, sex, site, tumor size, and margin status, grade 3 patients had a higher recurrence rate than grades 1 and 2 (HR=2.07, 95% CI: 1.24, 7.62; P=0.015). Patients with high-level MDM2 amplification had higher recurrence rate on univariate analysis (P=0.028), but not on multivariate analysis (HR=1.69, 95% CI: 0.73, 3.94; P=0.221). FNCLCC grade 3 dedifferentiation confers a worse prognosis in dedifferentiated liposarcoma in terms of local recurrence. MDM2 amplification level remains a useful diagnostic tool in

The objective of this nested study was to assess the prevalence of psychiatric disorders in a sample of HIV/hepatitis C virus (HCV)-coinfected patients according to their HCV status. The nested cross-sectional study, untitled HEPAVIH-Psy survey, was performed in a subset of HIV/HCV-coinfected patients enrolled in the French Agence Nationale de Recherche sur le SIDA et les Hépatites Virales (ANRS) CO13 HEPAVIH cohort. Psychiatric disorders were screened for using the Mini International Neuropsychiatric Interview (MINI 5.0.0). Among the 286 patients enrolled in the study, 68 (24%) had never received HCV treatment, 87 (30%) were treatment nonresponders, 44 (15%) were currently being treated and 87 (30%) had a sustained virological response (SVR). Of the 286 patients enrolled, 121 patients (42%) screened positive for a psychiatric disorder other than suicidality and alcohol/drug abuse/dependence, 40 (14%) screened positive for alcohol abuse/dependence, 50 (18%) screened positive for drug abuse/dependence, 50 (17.5%) were receiving an antidepressant treatment and 69 (24%) were receiving an anxiolytic. Patients with an SVR did not significantly differ from the other groups in terms of psychiatric disorders. Patients receiving HCV treatment screened positive less often for an anxiety disorder. The highest rate of drug dependence/abuse was among HCV treatment-naïve patients. Psychiatric disorders were frequent in HIV/HCV-coinfected patients and their rates were comparable between groups, even for patients achieving an SVR. Our results emphasize the need for continuous assessment and care of coinfected patients, even after HCV clearance. Drug addiction remains an obstacle to access to HCV treatment. Despite the recent advent and continued development of directly acting antiviral agents (DAAs), it is still crucial to offer screening and comprehensive care for psychiatric and addictive disorders. © 2016 British HIV Association.

Integration des sciences et de la langue: Creation et experimentation d'un modele pedagogique pour ameliorer l'apprentissage des sciences en milieu francophone minoritaire

Cormier, Marianne

Les faibles resultats en sciences des eleves du milieu francophone minoritaire, lors d'epreuves au plan national et international, ont interpelle la recherche de solutions. Cette these avait pour but de creer et d'experimenter un modele pedagogique pour l'enseignement des sciences en milieu linguistique minoritaire. En raison de la presence de divers degres de francite chez la clientele scolaire de ce milieu, plusieurs elements langagiers (l'ecriture, la discussion et la lecture) ont ete integres a l'apprentissage scientifique. Nous avions recommande de commencer le processus d'apprentissage avec des elements langagiers plutot informels (redaction dans un journal, discussions en dyades...) pour progresser vers des activites langagieres plus formelles (redaction de rapports ou d'explications scientifiques). En ce qui a trait a l'apprentissage scientifique, le modele preconisait une demarche d'evolution conceptuelle d'inspiration socio-constructiviste tout en s'appuyant fortement sur l'apprentissage experientiel. Lors de l'experimentation du modele, nous voulions savoir si celui-ci provoquait une evolution conceptuelle chez les eleves, et si, simultanement, le vocabulaire scientifique de ces derniers s'enrichissait. Par ailleurs, nous cherchions a comprendre comment les eleves vivaient leurs apprentissages dans le cadre de ce modele pedagogique. Une classe de cinquieme annee de l'ecole de Grande-Digue, dans le Sud-est du Nouveau-Brunswick, a participe a la mise a l'essai du modele en etudiant les marais sales locaux. Lors d'entrevues initiales, nous avons remarque que les connaissances des eleves au sujet des marais sales etaient limitees. En effet, s'ils etaient conscients que les marais etaient des lieux naturels, ils ne pouvaient pas necessairement les decrire avec precision. Nous avons egalement constate que les eleves utilisaient surtout des mots communs (plantes, oiseaux, insectes) pour decrire le marais. Les resultats obtenus indiquent que les eleves ont

Human immunodeficiency virus (HIV)-infected patients are at higher risk of malignancies. In addition to traditional determinants, a specific deleterious effect of HIV and immunodeficiency is speculated. We aimed at studying the association between immunological and virological characteristics of HIV-infected patients in care and the risk of acquired immunodeficiency syndrome (AIDS)-defining and non-AIDS-defining malignancies. Patients consecutively enrolled in the hospital-based Agence Nationale de Recherche sur le Sida (ANRS) CO3 Aquitaine Cohort were included if the duration of follow-up was >3 months during the period 1998-2006. Multivariate modeling used an extended Cox proportional hazards model for time-dependent covariates and delayed entry. The 4194 patients included in the study developed 251 first malignancies during 22,389 person-years. A higher incidence of AIDS-defining malignancies (107 cases) was independently associated with (1) both longer and current exposures to a plasma HIV RNA level >500 copies/mL (hazard ratio [HR], 1.27 per year [P<.001] and 3.30 [P<.001], respectively) and (2) both longer and current exposure to a CD4(+) cell count <200 cells/mm(3) (HR, 1.36 per year [P<.001] and 6.33 [P<.001], respectively). A higher incidence of non-AIDS-defining malignancies (144 cases) was independently associated with longer and current exposure to a CD4(+) cell count <500 cells/mm(3) (HR, 1.13 per year [P=.01] and 2.07 [P<.001], respectively) and male sex (HR, 1.69; P=.02) but not with plasma HIV RNA level (P=.49 and P=.10 for cumulative and current exposures, respectively). Uncontrolled plasma HIV RNA level was independently associated with a higher likelihood of developing AIDS-defining malignancies, whereas immunosuppression was associated with a higher risk of developing any type of malignancies. Antiretroviral treatment should aim at reaching and maintaining a CD4(+) count >500 cells/mm(3) to prevent the occurrence of malignancy, this should be

It has been extensively shown, mainly in US populations, that sugar-sweetened beverages (SSBs) are associated with increased risk of type 2 diabetes (T2D), but less is known about the effects of artificially sweetened beverages (ASBs). We evaluated the association between self-reported SSB, ASB, and 100% fruit juice consumption and T2D risk over 14 y of follow-up in the French prospective Etude Epidémiologique auprès des femmes de la Mutuelle Générale de l'Education Nationale-European Prospective Investigation into Cancer and Nutrition cohort. A total of 66,118 women were followed from 1993, and 1369 incident cases of T2D were diagnosed during the follow-up. Cox regression models were used to estimate HRs and 95% CIs for T2D risk. The average consumption of sweetened beverages in consumers was 328 and 568 mL/wk for SSBs and ASBs, respectively. Compared with nonconsumers, women in the highest quartiles of SSB and ASB consumers were at increased risk of T2D with HRs (95% CIs) of 1.34 (1.05, 1.71) and 2.21 (1.56, 3.14) for women who consumed >359 and >603 mL/wk of SSBs and ASBs, respectively. Strong positive trends in T2D risk were also observed across quartiles of consumption for both types of beverage (P = 0.0088 and P < 0.0001, respectively). In sensitivity analyses, associations were partly mediated by BMI, although there was still a strong significant independent effect. No association was observed for 100% fruit juice consumption. Both SSB consumption and ASB consumption were associated with increased T2D risk. We cannot rule out that factors other than ASB consumption that we did not control for are responsible for the association with diabetes, and randomized trials are required to prove a causal link between ASB consumption and T2D.

Privacy Laws and Biobanking in Germany.

Hoppe, Nils

2016-03-01

While the possibility of enacting a sui generis Biobank Act has been debated in Germany at great length, as of yet the country has not implemented any biobankspecific legislation. Instead, oversight is available via a network of research and privacy laws, including those of the European Union. The Nationale Kohorte, Germany's large-scale, population-based epidemiological research biobank, is funded by the Federal Ministry of Education and Research, and there are currently 108 registered bio-banks throughout Germany. The current system, including the structure and study design of the Nationale Kohorte, privileges the protection of personal information even at the cost of socially desirable research; it remains to be seen if forthcoming legislation will shift this balance. © 2016 American Society of Law, Medicine & Ethics.

To engage the public to understand how to improve the care of critically ill patients. A qualitative content analysis of an open community forum (Café Scientifique). Public venue in Calgary, Alberta, Canada. Members of the general public including patients, families of patients, health care providers, and members of the community at large. A panel of researchers, decision-makers, and a family member led a Café Scientifique, an informal dialogue between the populace and experts, over three-hours to engage the public to understand how to improve the care of critically ill patients. Conventional qualitative content analysis was used to analyze the data. The inductive analysis occurred in three phases: coding, categorizing, and developing themes. Thirty-eight members of the public (former ICU patients, family members of patients, providers, community members) attended. Participants focused the discussion and provided concrete suggestions for improvement around communication (family as surrogate voice, timing of conversations, decision tools) and provider well-being and engagement, as opposed to medical interventions in critical care. Café participants believe patient and family centered care is important to ensure high-quality care in the ICU. A Café Scientifique is a valuable forum to engage the public to contribute to priority setting areas for research in critical care, as well as a platform to share lived experience. Research stakeholders including health care organizations, governments, and funding organizations should provide more opportunities for the public to engage in meaningful conversations about how to best improve healthcare.

Science and technology are essential to sustainable development. They must be endogenous in nature to reduce the dependency and vulnerability of developing countries. Hence we seek to determine how Togolese students appropriate the field of science. Science education should answer fundamental educational needs by aiming for autonomy and individualization, that is, the skills and attitudes necessary to the resolution of, problems (and thus necessary to creativity), the concept of which includes the production of new ideas and adaptation to change. This basic scientific culture allows citizens to understand socioeconomic and environmental imperatives related to science and technology. This study answers the following questions: (1) How is the appropriation of knowledge by Togolese students favored? (2) What are the representations acquired by Togolese students in the science classroom regarding key research concepts, namely education, culture, science, knowledge and development? The objective of this research is to partially describe the context of science learning in the first cycle of the Second Degree in Togo, a French-language developing country of Africa, and particularly to understand the influence of the sociocultural setting on pedagogy and development. We first present our conception of science teaching, followed by the construction of knowledge in context. This research permits clearer propositions in terms of plausible explanations for the observed relationships among the categories of data. Indeed, the framework of the transmission of knowledge considerably influences the appropriation of the field of science by Togolese students. Science is a mythical and mystical field, still perceived as the "white mans's thing", in spite of favorable attitudes developed by students concerning the application of science and technology in their environment. By way of the favored learning methods (which also represent those of the traditional environment) and curricula (which are exogenous in nature), students formally appropriate scientific knowledge without actually transferring that knowledge outside the school setting. For this study, the validity of the propositions is dependent upon the perceptions of the key research concepts by the subjects. That is why the propositions are supported by the analysis of the Togolese student's answers during interviews, as well as by lectures given by African essayists. This is an a priori exploratory research, characterized by a qualitative methodology. The research concentrates on preliminary description and comprehension. Specifically, the method is based on an interpretive approach, while also being reflexive in nature. Observation data were gathered through documentation, field observations, a group discussion and a questionnaire. The pertinence of this study's results lies in a better understanding of the construction of knowledge in context.

Le recours aux modeles dans l'enseignement de la biologie au secondaire : Conceptions d'enseignantes et d'enseignants et modes d'utilisation

NASA Astrophysics Data System (ADS)

Varlet, Madeleine

Le recours aux modeles et a la modelisation est mentionne dans la documentation scientifique comme un moyen de favoriser la mise en oeuvre de pratiques d'enseignement-apprentissage constructivistes pour pallier les difficultes d'apprentissage en sciences. L'etude prealable du rapport des enseignantes et des enseignants aux modeles et a la modelisation est alors pertinente pour comprendre leurs pratiques d'enseignement et identifier des elements dont la prise en compte dans les formations initiale et disciplinaire peut contribuer au developpement d'un enseignement constructiviste des sciences. Plusieurs recherches ont porte sur ces conceptions sans faire de distinction selon les matieres enseignees, telles la physique, la chimie ou la biologie, alors que les modeles ne sont pas forcement utilises ou compris de la meme maniere dans ces differentes disciplines. Notre recherche s'est interessee aux conceptions d'enseignantes et d'enseignants de biologie au secondaire au sujet des modeles scientifiques, de quelques formes de representations de ces modeles ainsi que de leurs modes d'utilisation en classe. Les resultats, que nous avons obtenus au moyen d'une serie d'entrevues semi-dirigees, indiquent que globalement leurs conceptions au sujet des modeles sont compatibles avec celle scientifiquement admise, mais varient quant aux formes de representations des modeles. L'examen de ces conceptions temoigne d'une connaissance limitee des modeles et variable selon la matiere enseignee. Le niveau d'etudes, la formation prealable, l'experience en enseignement et un possible cloisonnement des matieres pourraient expliquer les differentes conceptions identifiees. En outre, des difficultes temporelles, conceptuelles et techniques peuvent freiner leurs tentatives de modelisation avec les eleves. Toutefois, nos resultats accreditent l'hypothese que les conceptions des enseignantes et des enseignants eux-memes au sujet des modeles, de leurs formes de representation et de leur approche

Introduction Il s'agit d'analyser la prise en charge du nouveau-né dans le cadre de la stratégie na-tionale de subvention des accouchements et des soins obstétricaux et néonatals d'urgence mis en place par le gouvernement du Burkina Faso en 2006. Méthodes Nous avons menée une étude à visée descriptive et analytique comportant un volet ré-trospectif du 01 janvier 2006 au 31 décembre 2010 portant sur les paramètres épidémiologiques, cliniques des nouveau-nés hospitalisés et un volet prospectif du 3 octobre 2011 au 29 février 2012 par une entrevue des accompagnateurs des nouveau-nés et des prestataires des services de santé. Résultats Les hospitalisations ont augmenté de 43,65% entre 2006 à 2010 Le taux de mortalité néo-natale hospitalière qui était de 11,04% a connu une réduction moyenne annuelle de 3,95%. L'entrevue a porté sur 110 accompagnateurs et 76 prestataires. La majorité des prestataires (97,44%) et des ac-compagnateurs (88,18%) étaient informés de la stratégie mais n'avait pas une connaissance exacte de sa définition. Les prestataires (94,74%) ont signalé des ruptures de médicaments, consommables médicaux et des pannes d’ appareils de laboratoire et d'imagerie. Parmi les accompagnateurs (89%) disaient être satisfaits des services offerts et (72,89%) trouvaient les coûts abordables mais évoquaient les difficultés du transport. Conclusion: La subvention a amélioré la prise en charge du nou-veau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. Conclusion La subvention a amélioré la prise en charge du nouveau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. PMID:26161166

La supraconductivité a 100 ans !

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lebrun, Philippe

2011-04-14

Il y a 100 ans, le 8 avril 1911, une découverte majeure était réalisée : celle de la supraconductivité. La supraconductivité est la caractéristique qu’ont certains métaux et alliages de perdre toute résistance électrique en dessous d’une température donnée. Cette renversante découverte, réalisée de manière presque fortuite par Kammerlingh Onnes de l’Université de Leyde (Pays-Bas) et son étudiant Gilles Holst, a ouvert un nouveau champ de recherche en physique et de fabuleuses perspectives d’applications technologiques. Du point de vue scientifique, la supraconductivité est en effet l’une des rares manifestations de la physique quantique à l’échelle macroscopique.  Du point de vuemore » des retombées techniques, elle est porteuse d’applications majeures dans le domaine de la santé, des communications et de l’énergie. 100 ans après, les physiciens n’ont toujours pas fini d’explorer ce phénomène et ses applications. Le CERN abrite des applications de la supraconductivité à des échelles inédites. L’accélérateur de particules LHC, avec ses milliers d’aimants supraconducteurs répartis sur 27 kilomètres de circonférence, est en effet la plus grande application mondiale de la supraconductivité. Il ne pourrait exister sans elle. Le CERN fête donc la découverte de la supraconductivité avec une conférence exceptionnelle donnée par Philippe Lebrun. Au cours de cette conférence, l’expérience historique de Kammerlingh Onnes sera reproduite. Philippe Lebrun racontera l’histoire de cette étonnante découverte, en la replaçant dans le contexte scientifique de l’époque. Il racontera les développements scientifiques et les applications du premier siècle de la supraconductivité.

2016-03-01

The topological pressure-temperature phase diagram for the dimorphism of spiperone, a potent neuroleptic drug, has been constructed using literature data and improved crystal structures obtained with new crystallographic data from single-crystal X-ray diffraction at various temperatures. It is inferred that form II, which is the more dense form and exhibits the lower melting temperature, becomes the more stable phase under pressure. Under ambient conditions, form I is more stable.

Passer en revue les connaissances scientifiques actuelles et formuler des recommandations relatives au diagnostic et à la prise en charge de la torsion annexielle chez les filles, les adolescentes et les femmes adultes. L'étude porte sur les facteurs de risque, la précision diagnostique, les options de prise en charge et les issues de la torsion annexielle. RéSULTATS: Nous avons examiné les études publiées en faisant des recherches dans MEDLINE, Embase, CINAHL et la Bibliothèque Cochrane à l'aide d'une terminologie contrôlée et de mots-clés appropriés (« adnexal torsion », « ovarian torsion »). Nous avons limité les résultats aux revues systématiques, aux essais contrôlés aléatoires, aux essais cliniques contrôlés et aux études d'observation. Nous avons refait les recherches de façon régulière et intégré de nouvelles données à la directive jusqu'en décembre 2014. Nous avons également étudié la littérature grise (non publiée) trouvée sur les sites Web d'organismes d'évaluation des technologies de la santé et d'autres organismes connexes, dans des collections de directives cliniques et dans des registres d'essais cliniques, et obtenue auprès d'associations nationales et internationales de médecins spécialistes. Les résultats ont été examinés et évalués par le comité CANPAGO de la Société des obstétriciens et gynécologues du Canada (SOGC), sous la direction des auteures principales. Les recommandations ont été classées selon les critères établis par le Groupe d'étude canadien sur les soins de santé préventifs. AVANTAGES, DéSAVANTAGES ET COûTS: L'application de la directive devrait aider les praticiens à adopter une approche de diagnostic et de prise en charge optimale en matière de torsion annexielle, à réduire au minimum les effets néfastes et à améliorer l'issue qui attend les patientes. La présente directive a été évaluée et approuvée par le Comité de pratique - gynécologie de la SOGC

2001-01-01

The transition in confined rotating flows is a topical problem with many industrial and fundamental applications. The purpose of this study is to investigate the Taylor-Couette flow in a finite-length cavity with counter-rotating walls, for two aspect ratios L=5 or L=6. Two complex regimes of wavy vortex and spirals are emphasized for the first time via direct numerical simulation, by using a three-dimensional spectral method. The spatio-temporal behavior of the solutions is analyzed and compared to the few data actually available. c2001 Academie des sciences/Editions scientifiques et medicales Elsevier SAS.

Démarche pour la mise à niveau d’un secteur de soins pharmaceutiques : le cas de l’hémato-oncologie pédiatrique

PubMed Central

Bussières, Jean-François; Robelet, Antoine; Therrien, Roxane; Touzin, Karine

2010-01-01

Contexte : Bien que le concept de pharmacie clinique ait été développé dans les années soixante, il existe une grande variété de programmes et une grande disparité entre les programmes en clinique externe et en hospitalisation, bénéficiant de la présence d’un pharmacien dans un secteur de soins. Objectif: Éprouver une méthode de mise à niveau des secteurs de soins pharmaceutiques en établissement de santé. Méthode : Il s’agit d’une étude descriptive se déroulant au Centre hospitalier universitaire Sainte-Justine, un établissement mère-enfant de 500 lits. Le secteur de soins pharmaceutiques ciblé pour illustrer la méthode de mise à niveau est l’hématologie-oncologie pédiatrique. La méthode comporte trois étapes, soit une revue de la documentation scientifique, un profil du secteur et une mise à jour du niveau de pratique selon un profil des activités pharmaceutiques dans le secteur avant et après la mise à niveau. Résultats : Au total, 108 articles ont été recensés et 22 ont été retenus à partir d’une recherche dans PubMed. Après une recherche manuelle complémentaire, 36 articles ont finalement été évalués. Parmi les articles retenus, on compte trois lignes directrices, 11 études de développement, une revue de la littérature scientifique, six études pré- et post-interventions et 15 études quasi expérimentales. Bien que les patients de ce secteur ne comptent que pour 5 % des admissions de l’hôpital, la complexité des cas est élevée tant sur le plan de la codification de l’épisode de soins que du potentiel d’intervention pharmaceutique par admission. Conclusion : Il existe peu de données illustrant une démarche de mise à niveau de la pratique dans un secteur de soins pharmaceutiques. Cette étude a éprouvé une méthode de mise à niveau dans un service d’hématologie-oncologie pédiatrique et comporte une revue de la documentation scientifique, un profil du secteur et une description des t

Paternité des articles et intérêts concurrents : une analyse des recommandations aux auteurs des journaux traitant de pratique pharmaceutique

2014-01-01

RÉSUMÉ Contexte : La présence d’auteurs honorifiques et fantômes ainsi que les intérêts concurrents représentent des difficultés bien documentées, liées à la publication d’articles scientifiques. Il existe des lignes directrices encadrant la rédaction et la publication de manuscrits scientifiques, notamment celles de l’International Committee of Medical Journal Editors (ICMJE). Objectifs : L’objectif principal de cette étude descriptive et transversale visait à recenser les instructions portant sur la paternité des articles et les intérêts concurrents provenant des recommandations aux auteurs des journaux traitant de pratique pharmaceutique. L’objectif secondaire visait à déterminer des mesures correctrices pour une paternité des articles plus transparente. Méthode : La recherche a débuté par l’identification des journaux traitant de pratique pharmaceutique. La consultation des instructions aux auteurs des journaux a permis ensuite de recenser les recommandations destinées à éviter les problèmes de paternité des articles et d’intérêts concurrents. Finalement, les membres de l’équipe de recherche se sont consultés afin de définir des mesures correctrices possibles à l’intention des chercheurs. Résultats : Des 232 journaux traitant de pharmacie, 33 ont été définis comme traitant de pratique pharmaceutique. Un total de 24 (73 %) journaux mentionnaient suivre la politique de l’ICMJE, 14 (42 %) demandaient aux auteurs de remplir un formulaire de déclaration d’intérêts concurrents au moment de la soumission de l’article, 17 (52 %) présentaient une définition de la qualité d’auteur et 5 (15 %) demandaient de détailler les contributions de chaque auteur. Une grille de 40 critères a été élaborée pour définir l’attribution du statut d’auteur. Conclusion : Moins de la moitié des journaux demandait aux auteurs de transmettre un formulaire de déclaration des intérêts concurrents au moment de la

Neurologic complications of post-partum are serious and usually secondary to eclampsia or stroke. We here report a 26-year-old female who presented with severe headaches, blurred vision, and repeated generalized seizures secondary to posterior reversible encephalopathy that occurred after a caesarean section for fetal death in utero. Outcome was favourable. Although uncommon, this neurologic complication of the post-partum should be discussed in the presence of any sign of encephalopathy occurring in the context of acute hypertension.

Myeloproliferative disorders and secondary polycythemia cover most of the polycythemia cases encountered in daily practice. Inherited polycythemias are rare entities that have to be suspected when the classical causes of acquired polycythemia have been ruled out. Recent advances were made in the understanding of these pathologies, which are still little known to the physicians. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of inherited polycythemia.

Lachièze-Rey, Marc; Luminet, Jean-Pierre

2001-07-01

Throughout history, the mysterious dark skies have inspired our imaginations in countless ways, influencing our endeavors in science and philosophy, religion, literature, and art. Filled with 380 full-color illustrations, Celestial Treasury shows the influence of astronomical theories and the richness of illustrations in Western civilization through the ages. The authors explore the evolution of our understanding of astronomy and weave together ancient and modern theories in a fascinating narrative. They incorporate a wealth of detail from Greek verse, medieval manuscripts and Victorian poetry with contemporary spacecraft photographs and computer-generated star charts. Celestial Treasury is more than a beautiful book: it answers a variety of questions that have intrigued scientists and laymen for centuries. -- How did philosophers and scientists try to explain the order that governs celestial motion? -- How did geometers and artists measure and map the skies? -- How many different answers have been proposed for the most fundamental of all questions: When and how did Earth come about? -- Who inhabits the heavens--gods, angels or extraterrestrials? No other book recounts humankind's fascination with the heavens as compellingly as Celestial Treasury.

Les nanostructures pour créer de la couleur, un art inspiré par la nature

NASA Astrophysics Data System (ADS)

Ball, Philip

2018-02-01

Les reflets changeants des plumes de la queue du paon ont captivé plus d'un esprit curieux. Le scientifique anglais Robert Hooke les qualifiait en 1665 de « surnaturelles » en constatant que, mouillées, elles perdaient leurs couleurs. À l'aide du microscope inventé depuis peu, il observa ces plumes, et découvrit qu'elles étaient couvertes de stries - qu'il suspecta d'être à l'origine des couleurs. Aujourd'hui, la recherche tente de s'inspirer de ces phénomènes : des applications « bio-inspirées » sont en voie de concrétisation. ARRAY(0x29ad218)

2015-08-01

One of the most important current trends in astronomy communication has been “change”. The field of astronomy communication has rapidly evolved in just the past few years, as new techniques and technologies have been adopted. Research astronomy has also visibly changed, as automation of survey systems and the launch of new telescopes has produced a tsunami of big data sets. Today, scientists and communicators must work together to navigate the raging waters of this data flood as they strive to keep our tech-savvy society informed.

Pachymeningitis is a fibrosing and inflammatory process, which involves the dura mater. Some pachymeningitis are cranial and induce headaches and cranial nerve palsies. Others are spinal and responsible for nerve roots or spinal cord compression. MRI shows contrast enhancement thickening of the dura mater. Etiologies are infectious (syphilis, tuberculosis, etc.) or inflammatory (sarcoidosis, granulomatosis with polyangiitis, IgG4-related disease, idiopathic). Corticosteroids are the main treatment. The use of immunosuppressive drugs or rituximab is yet to be determined and probably adapted to each etiology. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Hydrogeological Investigations in Deep Wells at the Meuse/Haute Marne Underground Research Laboratory

NASA Astrophysics Data System (ADS)

Delay, Jacques; Distinguin, Marc

ANDRA (Agence Nationale pour la Gestion de Déchets Radioactifs) has developed an integrated approach to characterizing the hydrogeology of the carbonate strata that encase the Callovo-Oxfordian argillite at the Meuse/Haute-Marne Laboratory site. The argillites are difficult to characterize due to their low permeability. The barrier properties of the argillites can be inferred from the flow and chemistry properties of the encasing Oxfordian and Dogger carbonates. Andras deep hole approach uses reverse air circulation drilling, geophysical logging, flow meter logging, geochemical sampling, and analyses of the pumping responses during sampling. The data support numerical simulations that evaluate the argillites hydraulic behaviour.

The topological phase diagram of cimetidine: A case of overall monotropy.

Cimetidine is a histamine H 2 -receptor antagonist used against peptic ulcers. It is known to exhibit crystalline polymorphism. Forms A and D melt within 0.35 degrees from each other and the enthalpies of fusion are similar as well. The present paper demonstrates how to construct a pressure-temperature phase diagram with only calorimetric and volumetric data available. The phase diagram provides the stability domains and the phase equilibria for the phases A, D, the liquid and the vapor. Cimetidine is overall monotropic with form D the only stable solid phase.

Pleural effusion management is a common clinical situation associated with numerous pulmonary, pleural or extra-pulmonary diseases. A systematic approach is needed to enable a rapid diagnosis and an appropriate treatment. Pleural fluid analysis is the first step to perform which allows a presumptive diagnosis in most cases. Otherwise, further analysis of the pleural fluid or thoracic imaging or pleural biopsy may be necessary. This review aims at highlighting the important elements of the work-up required by a pleural effusion. Copyright © 2014 Société nationale française de médecine interne (SNFMI).

La supraconductivité a 100 ans !

ScienceCinema

Lebrun, Philippe

2018-06-12

Il y a 100 ans, le 8 avril 1911, une découverte majeure était réalisée : celle de la supraconductivité. La supraconductivité est la caractéristique qu’ont certains métaux et alliages de perdre toute résistance électrique en dessous d’une température donnée. Cette renversante découverte, réalisée de manière presque fortuite par Kammerlingh Onnes de l’Université de Leyde (Pays-Bas) et son étudiant Gilles Holst, a ouvert un nouveau champ de recherche en physique et de fabuleuses perspectives d’applications technologiques. Du point de vue scientifique, la supraconductivité est en effet l’une des rares manifestations de la physique quantique à l’échelle macroscopique.  Du point de vue des retombées techniques, elle est porteuse d’applications majeures dans le domaine de la santé, des communications et de l’énergie. 100 ans après, les physiciens n’ont toujours pas fini d’explorer ce phénomène et ses applications. Le CERN abrite des applications de la supraconductivité à des échelles inédites. L’accélérateur de particules LHC, avec ses milliers d’aimants supraconducteurs répartis sur 27 kilomètres de circonférence, est en effet la plus grande application mondiale de la supraconductivité. Il ne pourrait exister sans elle. Le CERN fête donc la découverte de la supraconductivité avec une conférence exceptionnelle donnée par Philippe Lebrun. Au cours de cette conférence, l’expérience historique de Kammerlingh Onnes sera reproduite. Philippe Lebrun racontera l’histoire de cette étonnante découverte, en la replaçant dans le contexte scientifique de l’époque. Il racontera les développements scientifiques et les applications du premier siècle de la supraconductivité. Conférence en français Merci de bien vouloir vous inscrire au : +41 22 767 76 76

2015-04-01

The Kingdom of Morocco is a country of 33 million people where about thirty French schools enroll 32,000 students including a majority of Moroccans. The Rabat Center includes several institutions enrolling 5,700 students aged 10 to 18 years old whose High School René Descartes is directed by the A.E.F.E, "Agency for French Teaching Abroad". Sixteen professors teach S.V.T. "Sciences de la Vie et de la Terre" that focuses on biology and geology. The programs involved are French but the biology-geology colleagues seek to place the teaching of geology in the context of Morocco through the choice of Moroccan examples. (https://sites.google.com/site/aefesvtmaroc/) Morocco's geology lends itself to this approach! The laboratory is equipped with a seismometer in the network "Sismos to School" (https://sites.google.com/a/lycee-descartes.ma/rabt_sismo/home) and we have the equipment necessary for making thin sections of the Moroccan rocks for practical work on a polarizing microscope. We organize several field trips: On a half-day in the region of Rabat, 12-year old pupils of "5ème", learn about reading the landscape and studying sedimentary rocks such as marls and sandstones. On a 3-day excursion in the region of Azrou, the16-year old pupils of "première scientifique" study the tectonic context of formation of mineral resources. A 2-day trip in the region of Oulmès, the17-year old pupils of "terminale scientifique" (the last year in the French system finishing with the "baccalaureate") study continental crust, tectonics and geothermal energy. These field trips will be presented in this poster. Students make field studies: observation, testing, photography, drawing and taking notes. Some works are evaluated during the field trip, others are the subject of home work: preparing a slide show, an audio recording work...

1999-03-01

In his paper Les épistémologies constructivistes: Un nouveau commencement (Sciences de la Société, n°40, 1997), Jean-Louis Le Moigne poses the question: "Le rêve d'une connaissance autoréférentielle se fondant sur elle-même, est sans doute fascinant … Mais est-il scientifiquement raisonnable?". Building on the work of Jean Piaget, I shall try to show through a developmental analysis of elementary, scientifically relevant concepts, such as `change', `object permanence', `space', and `time', that the notion of the thinking subject's construction of knowledge constitutes a more reasonable foundation for science than the traditional belief in the representation of objective reality.

Science Cafes are live and lively events that take place in casual settings such as coffeehouses or bars, are open to everyone, and feature an engaging conversation with a scientist about a compelling scientific topic. The Science Cafe movement in the United States is a grassroots effort to really engage the public in discussions about science and its relevance to society, inspired by the United Kingdom Cafe Scientifique organization. With support from NOVA and the related website sciencecafes.org, a number of Society of Physics Students chapters hosted local Cosmic Cafes (cosmic themed science cafes) in late 2011 and early 2012. This presentation will discuss the goals and models of the Science Cafe movement, the Cosmic Cafe effort, lessons learned, and how you can get involved.

2009-02-01

This paper presents results from a qualitative study of perceptions of science careers in the Centre National de la Recherche Scientifique (CNRS), the main research institution in France. Its aim is to understand the 'glass ceiling' effect, which reduces the proportion of women at the higher levels of the career hierarchy. Long interviews were carried out with men, as well as women, support staff and researchers. Factors such as tension between individual and collective dimensions of research activity, and long-term time-management problems, were identified: these affect both men and women but in different ways. Organizations bear an important responsibility through the way they reinforce or alleviate difficulties that women and men face in contributing to scientific research at all levels.

Evolutionary medicine represents an innovative approach deriving from evolutionary biology. It includes the initial Darwin's view, its actualization in the light of progresses in genetics and also dissident theories (i.e. non gene-based) particularly epigenetics. This approach enables us to reconsider the pathophysiology of numerous diseases, as for instance, infection, and our so-called diseases of civilization especially obesity, type 2 diabetes, allergy or cancer. Evolutionary medicine may also improve our knowledge regarding inter-individual variation in susceptibility to disease or drugs. Furthermore, it points out the impact of our behaviors and environment on the genesis of a series of diseases. Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

Hereditary angioedema is a rare disease, often diagnosed with delay because of a heterogeneous clinical presentation. Before diagnosis, patients frequently present subcutaneous edema or abdominal pains during many years. Laryngeal edema can be life-threatening. Hereditary angioedema may impair the quality of life of the patients and their social and professional life. It is important that the physicians recognize and treat the disease as soon as possible after the first attacks. Since the past five years, new drugs developed for hereditary angioedema have changed dramatically the outcome of this disorder. The objective of this review is to detail the new therapeutic guidelines. Copyright © 2012 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Several cases of hearing loss induced by hydroxychloroquine have been reported in the literature but the role of hydroxychloroquine still remains debated. We report the first case, to our knowledge, of hearing loss induced by hydroxychloroquine with a positive re challenge in a woman treated for systemic lupus. An analysis of the French pharmacovigilance database allowed to identify 23 additional cases of hearing loss in patients treated with hydroxychloroquine and, among them, 8 had systemic lupus. Despite an excellent tolerance and high efficacy-side effect ratio, this case report adds some evidence for an otoxicity of hydroxychloroquine.

Antineutrophil cytoplasmic antibodies (ANCA) associated with infective endocarditis are a rare disorder. The condition can mimic primary systemic vasculitis (i.e. granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis). Thus, a wrong diagnosis of valvular involvement related to primary systemic vasculitis can be made in patients exhibiting ANCA associated with infective endocarditis. Because treatment of both conditions is different, this wrong diagnosis will lead to dramatic consequences in these latter patients. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of ANCA associated with infective endocarditis.

Challenges to reestablishment of free-ranging populations of black-footed ferrets

2003-01-01

The black-footed ferret (Mustela nigripes) of North America is critically endangered due in part to its extreme specialization on formerly stable and abundant prairie dogs (Cynomys). Its close relative, the Siberian polecat (M. eversmannii) seems to have been subjected to a varying environment that was not conducive to specialization. One source of environmental variation in Asian steppes was plague (caused by Yersina pestis), which was absent from North America. Introduction of plague to North America presents serious challenges to ferret recovery. Partial solutions to other biological and political problems have been found, resulting in improved production in captivity, increased survival post-release, and thriving populations in plague-free South Dakota. ?? 2003 Acade??mie des sciences.

Amyloidosis is mainly a systemic disease belonging to protein-folding diseases. The past 10 years have shown significant progress in typing and the clinical management of amyloidosis, in the identification of novel prognostic markers for risk-stratification, and also in the development of new therapeutic agents. Biological molecular techniques are now able to type amyloidosis which were unidentified. Cardiac MRI and biomarkers allow a precise risk-stratification, especially in AL amyloidosis. If necessary, this prognostic evaluation may lead to rapid changes in the chemotherapy treatment. Emerging treatments rely on biotherapies, gene therapy, immunotherapy and blocking analogous agents. They give hope about an increase of survival of patients with systemic amyloidosis. Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS.

2017-09-01

Sarcoidosis is a systemic granulomatous disorder of unknown cause. Apparition or flare of previously diagnosed sarcoidosis following hematopoietic stem cell transplantation (HSCT) has rarely been reported. We report a 62-year-old woman who presented a radiological flare of sarcoidosis post-autologous stem cell transplantation for a POEMS syndrome. Imaging findings and lymph node histology, which revealed non-caseating granuloma, were consistent with the sarcoidosis diagnosis. The patient was asymptomatic and was kept free of treatment. Sarcoidosis must be considered ahead of compatible clinicoradiological presentation occurring after HSCT. Sarcoidosis can mimic metastatic cancer or lymphatic relapse. Tissue biopsies and exclusion of differential diagnosis of granuloma diseases are warranted to confirm sarcoidosis diagnosis. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Electric-field control of spin waves in multiferroic BiFeO3: Theory

de Sousa, Rogério; Rovillain, P.; Gallais, Y.; Sacuto, A.; Méasson, M. A.; Colson, D.; Forget, A.; Bibes, M.; Barthélémy, A.; Cazayous, M.

2011-03-01

Our recent experiment demonstrated gigantic (30%) electric-field tuning of magnon frequencies in multiferroic BiFeO3. We demonstrate that the origin of this effect is related to two linear magnetoelectric interactions that couple the component of electric field perpendicular to the ferroelectric vector to a quadratic form of the Néel vector. We calculate the magnon spectra due to each of these interactions and show that only one of them is consistent with experimental data. At high electric fields, this interaction induces a phase transition to a homogeneous state, and the multi-magnon spectra will fuse into two magnon frequencies. We discuss the possible microscopic mechanisms responsible for this novel interaction and the prospect for applications in magnonics.

Approximately 1.5% of dementia is due to curable aetiology. We report an isolated dementia syndrome due to a meningeal relapse of acute promyelocytic leukaemia with favourable outcome after appropriate treatment. A 72-year-old woman, in remission of an acute promyelocytic leukaemia, presented a loss of autonomy for several months due to corticosubcortical dementia. Lumbar puncture showed blast cells indicating meningeal relapse of leukaemia. Intrathecal chemotherapy and arsenic trioxide obtained biological and molecular remission as well as restoration of normal cognitive functions. In patients with hematologic past history such as acute promyelocytic leukaemia, an isolated cognitive impairment should alert physicians to search for an isolated neuromeningeal relapse.

From dipolar to multipolar interactions between ultracold Feshbach molecules

NASA Astrophysics Data System (ADS)

Quéméner, Goulven; Lepers, Maxence; Luc-Koenig, Eliane; Dulieu, Olivier

2016-05-01

Using the multipolar expansion of electrostatic and magnetostatic potential energies, we characterize the long-range interactions between two weakly-bound diatomic molecules, taking as an example the paramagnetic Er2 Feshbach molecules which were produced recently. The interaction between atomic magnetic dipoles gives rise to the usual R-3 leading term of the multipolar expansion, where R is the intermolecular distance. We show that additional terms scaling as R-5, R-7 and so on also appear, which are strongly anisotropic with respect to the orientation of the molecules. These terms can be seen as effective molecular multipole moments reflecting the spatial extension of the molecules which is non-negligible compared to R. We acknowledge the financial support of the COPOMOL project (ANR-13-IS04-0004) from Agence Nationale de la Recherche.

Postural tachycardia syndrome (PoTS) is a multifactorial syndrome defined by an increase in heart rate ≥30bpm, within 10minutes of standing (or during a head up tilt test to at least 60°), in absence of orthostatic hypotension. It is associated with symptoms of cerebral hypoperfusion that are worse when upright and improve in supine position. Patients have an intense fatigue with a high incidence on quality of life. This syndrome can be explained by many pathophysiological mechanisms. It can be associated with Ehlers-Danlos disease and some autoimmune disorders. The treatment is based on nonpharmacological measures and treatment with propranolol, fludrocortisone or midodrine. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

[National ethics committees and representative democracy: is the new German ethics committee more "democratic"?].

PubMed

Dagron, Stéphanie

2007-01-01

The bill passed in April 2007 by the German parliament aims to confer democratic legitimacy on the German Ethics Committee (deutscher Ethikrat) which has replaced the former National Ethics Committee (nationaler Ethikrat) set up in 2001. This law results from a wide debate which began in 2005 within the political parties about the role in democracy of the bodies charged with advising the people's representatives in the areas of biotechnology and modern medicine. In this article, the author explains why it was necessary to confer a certain democratic legitimacy on the new Ethics Committee and analyses the relation that exists between the democratic principle, the work of this type of committee and the national institutional structure retained to stimulate the debate and advise the political decision-makers, and even to prepare legislation concerning bioethics.

Lemierre's syndrome is a rare and severe sepsis that can rapidly lead to a life-threatening condition in the absence of early management. This syndrome described at the beginning of the 20th century combines oropharyngeal infection complicated with septic thrombosis of the internal jugular vein and septic emboli predominantly pulmonary. Fusobacterium necrophorum, anaerobic germ, Gram negative bacillus is the main germ in this "necrobacillosis". The diagnosis is should be confirmed precociously with cervicothoracic CT-scan, reference exam, and bacteriological examinations (especially in atypical forms). Its management consists of an emergency antibiotic treatment, combining a third-generation cephalosporin or a betalactam with metronidazole, anticoagulant therapy to be reserved for high-risk situations related to thrombosis. Surgical treatment may be required. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Hemorrhoids are a common medical problem that is often considered as benign. The French Society of Colo-Proctology (Société nationale française de colo-proctologie [SNFCP]) recently revised its recommendations for the management of hemorrhoids (last issued in 2001), based on the literature and consensual expert opinion. We present a short report of these recommendations. Briefly, medical treatment, including dietary fiber, should always be proposed in first intention and instrumental treatment only if medical treatment fails, except in grade ≥III prolapse. Surgery should be the last resort, and the patient well informed of the surgical alternatives, including the possibility of elective ambulatory surgery, if appropriate. Postoperative pain should be prevented by the systematic implementation of a pudendal block and multimodal use of analgesics. Copyright © 2016. Published by Elsevier Masson SAS.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder. Drug-induced TTP is uncommon and we report a TTP associated with the use of clopidogrel. We report a 50-year-old man who presented with acute myocardial infarction and received clopidogrel therapy. He developed acute TTP ten days after clopidogrel onset. Imputability of the drug was demonstrated during a reintroduction test. Deficiency of ADAMTS 13 was confirmed and autoantibodies against ADAMTS 13 were detected. Complete remission was obtained after 24 plasma exchange sessions and adjunction of corticosteroids. Drug-induced TTP are probably immunologic, as was demonstrated in our patient. Clinicians should be aware of this possible uncommon adverse effect of clopidogrel because prompt therapy is imperative for life saving.

2015-05-01

Thrombotic microangiopathies (TMA) define a syndrome characterized by the association of microangiopathic haemolytic anaemia with schistocytes, peripheral thrombocytopenia, and organ injury of variable severity. Thrombotic thrombocytopenic purpura (TTP) and atypical haemolytic uremic syndrome (HUS) are the main forms of TMA. Recent advances in the pathophysiology of those two diseases, which include in HUS the identification of a deregulation of the alternative complement pathway, and in TTP a severe deficiency in ADAMTS-13, allowed to develop specific, pathophysiology-based therapies. Therefore, rituximab and eculizumab tends to be increasingly used, and there is an urgent need to define consensual modes of administration at the international level, as well as common definitions of response evaluation and follow-up explorations.

Organophosphorus coumpounds (OP) are toxic chemicals mainly used for agricultural purpose such as insecticides and were also developed and used as warfare nerve agents. OP are inhibitors of acetylcholinesterase, a key enzyme involved in the regulation of the central nervous system. Chemical, physical and biological approaches have been considered to decontaminate OP. This review summarizes the current and emerging strategies that are investigated to tackle this issue with a special emphasis on enzymatic remediation methods. During the last decade, many studies have been dedicated to the development of biocatalysts for OP removal. Among these, recent reports have pointed out the promising enzyme SsoPox isolated from the archaea Sulfolobus solfataricus. Considering both its intrinsic stability and activity, this hyperthermostable enzyme is highly appealing for the decontamination of OP. Copyright © 2017 Académie Nationale de Pharmacie.

Mondor's disease is a rare superficial thrombophlebitis, historically involving the thoracic venous system of women. However, it can occur in both gender and all over the skin. We report a 40-year-old man with type one diabetes who presented with a thrombosis of the superficial dorsal vein of the penis that he treated as a fungal infection. Treatment with non-steroidal anti-inflammatory drugs and low molecular weight heparin contributed to a favorable outcome in 2 weeks. Pathogenesis and treatment of Mondor's disease remain incompletely dominated. Some predisposing factors have been highlighted in the literature. It might be interesting to add diabetes, due to its frequent pelvic problems leading to a potential venous inflammatory trigger.

The French National Compound Library (Chimiothèque Nationale) has been created in 2003 and is the federation of local collections. It contains more than 56 000 small molecules and natural compounds synthesised or isolated in different laboratories over the past years. This explains the diversity of the collection. The strength of this initiative is the ability to connect chemists and biologists for the development of hits. This development involves the synthesis of analogues or/and chemical tools to find new targets. These collaborations lead to the identification of new chemical probes. These probes able to modulate a biological function are essential to study biological pathways. They can also be useful for therapeutic applications. This article will describe the major achievements and perspectives of the French Chemical Library. © 2015 médecine/sciences – Inserm.

The heart involvement in systemic sclerosis is frequent and can touch various sites. The prognosis in the presence of heart disease is poor, but few data are available about its management. We report the case of 48 years old woman with systemic sclerosis which presented severe heart involvement. She has severe heart failure, supraventricular arrhythmias and symptomatic pericarditis, which required surgical intervention and immunosuppressive drugs (steroids with rituximab). Despite this treatment, she has persistent severe heart impaired function and intravenous immunoglobulins have been initiated. She experienced progressively the improvement of dyspnea, of heart systolic ejection fraction and decrease of Rodnan scale. Our case illustrates a severe heart involvement in systemic sclerosis which have been improved by intravenous immunoglobulins.

Organizational Strategies for Critical Transportation Infrastructure: Characteristics of Urban Resilience. The Case of Montreal. Stéphane Beauregard M.Sc. Candidate École nationale d'administration publique Julie-Maude Normandin Ph.D. Candidate École nationale d'administration publique Marie-Christine Therrien Professor École nationale d'administration publique The proposed paper presents preliminary results on the resilience of organizations managing critical infrastructure in the Metropolitan Montreal area (Canada). A resilient city is characterized by a network of infrastructures and individuals capable of maintaining their activities in spite of a disturbance (Godschalk, 2002). Critical infrastructures provide essential services for the functioning of society. In a crisis situation, the interruption or a decrease in performance of critical infrastructures could have important impacts on the population. They are also vulnerable to accidents and cascading effects because on their complexity and tight interdependence (Perrow, 1984). For these reasons, protection and security of the essential assets and networks are one of the objectives of organizations and governments. But prevention and recovery are two endpoints of a continuum which include also intermediate concerns: ensuring organizational robustness or failing with elegance rather than catastrophically. This continuum also includes organizational resilience (or system), or the ability to recover quickly after an interruption has occurred. Wildavsky (1988) proposes that anticipation strategies work better against known problems while resilience strategies focus on unknown problems. Anticipation policies can unnecessarily immobilize investments against risks, while resilience strategies include the potential for a certain sacrifice in the interests of a more long-term survival and adaptation to changing threats. In addition, a too large confidence in anticipation strategies can bring loss of capacity of an

Magnetic field structure in single late-type giants: The weak G-band giant 37 Comae from 2008 to 2011

Aims: This work studies the magnetic activity of the late-type giant 37 Com. This star belongs to the group of weak G-band stars that present very strong carbon deficiency in their photospheres. The paper is a part of a global investigation into the properties and origin of magnetic fields in cool giants. Methods: We use spectropolarimetric data, which allows the simultaneous measurement of the longitudinal magnetic field Bl, line activity indicators (Hα, Ca II IRT, S-index) and radial velocity of the star, and consequently perform a direct comparison of their time variability. Mean Stokes V profiles are extracted using the least squares deconvolution (LSD) method. One map of the surface magnetic field of the star is reconstructed via the Zeeman Doppler imaging (ZDI) inversion technique. Results: A periodogram analysis is performed on our dataset and it reveals a rotation period of 111 days. We interpret this period to be the rotation period of 37 Com. The reconstructed magnetic map reveals that the structure of the surface magnetic field is complex and features a significant toroidal component. The time variability of the line activity indicators, radial velocity and magnetic field Bl indicates a possible evolution of the surface magnetic structures in the period from 2008 to 2011. For completeness of our study, we use customized stellar evolutionary models suited to a weak G-band star. Synthetic spectra are also calculated to confirm the peculiar abundance of 37 Com. Conclusions: We deduce that 37 Com is a 6.5 M⊙ weak G-band star located in the Hertzsprung gap, whose magnetic activity is probably due to dynamo action.

Context. The evolution of massive stars is still partly unconstrained. Mass, metallicity, mass loss, and rotation are the main drivers of stellar evolution. Binarity and the magnetic field may also significantly affect the fate of massive stars. Aims: Our goal is to investigate the evolution of single O stars in the Galaxy. Methods: For that, we used a sample of 74 objects comprising all luminosity classes and spectral types from O4 to O9.7. We relied on optical spectroscopy obtained in the context of the MiMeS survey of massive stars. We performed spectral modelling with the code CMFGEN. We determined the surface properties of the sample stars, with special emphasis on abundances of carbon, nitrogen, and oxygen. Results: Most of our sample stars have initial masses in the range of 20 to 50 M⊙. We show that nitrogen is more enriched and carbon and oxygen are more depleted in supergiants than in dwarfs, with giants showing intermediate degrees of mixing. CNO abundances are observed in the range of values predicted by nucleosynthesis through the CNO cycle. More massive stars, within a given luminosity class, appear to be more chemically enriched than lower mass stars. We compare our results with predictions of three types of evolutionary models and show that for two sets of models, 80% of our sample can be explained by stellar evolution including rotation. The effect of magnetism on surface abundances is unconstrained. Conclusions: Our study indicates that in the 20-50 M⊙ mass range, the surface chemical abundances of most single O stars in the Galaxy are fairly well accounted for by stellar evolution of rotating stars.

Georges Lemaître and Stigler's Law of Eponymy

NASA Astrophysics Data System (ADS)

Block, David L.

One of the greatest discoveries of modern times is that of the expanding Universe, almost invariably attributed to Hubble (Proceedings of the National Academy of Sciences of the United States of America 15:168, 1929). What is not widely known is that the original treatise by Lemaître (Annales de la Société Scientifique de Bruxelles, Sèrie A 47:49, 1927) contained a rich fusion of both theory and of observation. The French paper was meticulously censored when published in English: all discussions of radial velocities and distances, and the very first empirical determination of H 0 , were suppressed. Stigler's law of eponymy is yet again affirmed: no scientific discovery is named after its original discoverer (Merton, American Sociological Review 22(6):635, 1957). An appeal is made for a Lemaître Telescope naming opportunity, to honour the discoverer of the expanding universe.

Entreprendre une recherche sur la politique et la législation en matière d'éducation des adultes, qui couvre plusieurs secteurs, paraît une gageure pour plusieurs raisons: difficultés dans la constitution de plusieurs équipes de recherche avec plusieurs spécialistes ou personnes ressources, difficultés dans la collecte des données, étendue et complexité des domaines à explorer et des points à prendre en compte dans la rédaction, etc. En dépit de ces difficultés majeures, l'essentiel du travail a été accompli dans le souci de respecter les exigences imposées. A l'analyse, nous constatons que plusieurs partenaires interviennent dans la formation, l'éducation et l'encadrement des adultes, et que dans le secteur public, les structures ne sont pas "logées à la même enseigne": Si la formation professionnelle a bénéficié de conditions réellement favorables pour son expansion et son développement, les autres secteurs, sans avoir été négligés, n'ont pas connu les mêmes faveurs. Ainsi plusieurs lois et mesures importantes ont été votées et prises en vue de la dynamisation de la formation professionnelle, alors que le secteur de l'agriculture, qui est la base de succès du développement du pays et occupe 55% de la population, n'a pas bénéficié d'une véritable politique éducative en faveur des agriculteurs. Il en est de même pour l'alphabétisation. On déplore constamment l'absence de politique élaborée et appliquée à l'échelle nationale. Aucune mesure politique n'a été votée par l'Assemblée nationale, alors que l'alphabétisation devrait constituer le levier du développement de l'éducation des adultes en Côte d'lvoire.

Recently, we have successfully created an ultracold sample of absolute ground-state NaRb molecules by two-photon Raman transfer of weakly bound Feshbach molecules. Here we will present the detailed spectroscopic investigations on both the excited and the rovibrational ground states for finding the two-photon path. For the excited state, we focus on the A1Σ+ /b3 Π singlet and triplet admixture. We discovered an anomalously strong coupling between the Ω =0+ and 0- components which renders efficient population transfer possible. In the ground state, the pure nuclear hyperfine levels have been clearly resolved, which allows us to create molecules in the absolute ground state directly with Raman transfer.

Bovine ketosis is a rare cause of metabolic acidosis. It is a starvation ketosis that appears in lactating woman. A 29-year-old woman had a previous gastric surgery one month ago while breastfeeding her 6-month child. She presented to emergency with dyspnea, fatigue, weight loss and anorexia. The explorations revealed a serious metabolic acidosis with a high anion gap, for which all other causes have been eliminated. A restrictive diet in lactating patients is a major risk of ketosis or bovine ketosis. Medico-surgical treatment of obesity during lactation seems unreasonable. Breastfeeding should be systematically sought before a medical and surgical management of obesity. With the spread of bariatric surgery, starvation ketosis is a cause of metabolic acidosis not to ignore. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

2016-01-01

After a short review of the controversies surrounding the discovery of crystalline polymorphism in relation to our present day understanding, the methods of how to solve the stability hierarchy of different polymorphs will be briefly discussed. They involve either theoretical calculations, or, more commonly, experimental methods based on classical thermodynamics. The experimental approach is mainly carried out using heat-exchange data associated to the transition of one form into another. It will be demonstrated that work-related data associated to the phase transition should be taken into account and the role of X-ray crystallography therein will be discussed. X-ray crystallography has become increasingly precise and can nowadays provide specific volumes and their differences as a function of temperature, and also as a function of pressure, humidity, and time.

During the 18th and 19th centuries, numerous "entrepreneurs de spectacles scientifiques" — a new category of "stall-keepers" — travelled around France, displaying their scientific shows to the public. They turned out to be physics demonstrators, magicians, mechanical engineers or curators of museums of anatomy. A general survey of these shows is not easy because we have but few documents to consider. Through a various set of texts and pictures, we'll try to understand the general philosophy of these shows: the wonder, the novelty and the surprising are the key-ideas which prevail and not only the idea that these shows mostly deliver knowledge. But above all, we will see that these shows played an important part in popularizing the 19th century scientific achievement as well as achieving the 18th century goal of the Enlightenment. Finally, we may question and discuss the 21st century answer to the question of science understood as entertainment: "science'tainment" as we say: "info'tainment"!

NADH oxidase activities measured with excised roots of dark-grown maize (Zea mays) seedlings and with isolated plasma membrane vesicles from roots of dark-grown maize oscillated with a regular period length of 24 min and were inhibited by the synthetic auxin 2,4-dichlorophenoxyacetic [correction of dichorophenoxyacetic] acid. The activities also responded to orientation with respect to gravity and to imposed centrifugal forces. Turning the roots upside down resulted in stimulation of the activity with a lag of about 10 min. Returning the sections to the normal upright position resulted in a return to initial rates. The activity was stimulated reversibly to a maximum of about 2-fold with isolated plasma membrane vesicles, when subjected to centrifugal forces of 25 to 250 x g for 1 to 4 min duration. These findings are the first report of a gravity-responsive enzymatic activity of plant roots inhibited by auxin and potentially related to the gravity-induced growth response. c2001 Editions scientifiques et medicales Elsevier SAS.

Master equation with quantized atomic motion including dipole-dipole interactions

Damanet, François; Braun, Daniel; Martin, John

2016-05-01

We derive a markovian master equation for the internal dynamics of an ensemble of two-level atoms including all effects related to the quantization of their motion. Our equation provides a unifying picture of the consequences of recoil and indistinguishability of atoms beyond the Lamb-Dicke regime on both their dissipative and conservative dynamics, and is relevant for experiments with ultracold trapped atoms. We give general expressions for the decay rates and the dipole-dipole shifts for any motional states, and we find analytical formulas for a number of relevant states (Gaussian states, Fock states and thermal states). In particular, we show that the dipole-dipole interactions and cooperative photon emission can be modulated through the external state of motion. The effects predicted should be experimentally observable with Rydberg atoms. FD would like to thank the F.R.S.-FNRS for financial support.

Remote entanglement stabilization for modular quantum computing

NASA Astrophysics Data System (ADS)

Didier, Nicolas; Shankar, S.; Mirrahimi, M.

Quantum information processing in a modular architecture requires to distribute and stabilize entanglement in a qubit network. We present autonomous entanglement stabilization protocols between two qubits that are coupled to distant cavities. The cavities coupling is mediated and controlled via a three-wave mixing device that generates either a delocalized mode or a two-mode squeezed state between the remote cavities depending on the pump frequency. Local drives on the qubits and the cavities steer and maintain the system to the desired qubit Bell state. We show that these reservoir-engineering based protocols stabilize entanglement in presence of qubit-cavity asymmetries and losses. Most spectacularly, even a weakly-squeezed state can stabilize a maximally entangled Bell state of two distant qubits through entanglement accumulation.

Opsoclonus-myoclonus-ataxia (OMS) is a rare clinical syndrome, of paraneoplastic infectious, post-infectious, post-vaccinal or idiopathic origin. We report a 24-year-old young man who presented with gait disorder preceded by a febrile rash and retroauricular lymph nodes. Three days before admission, he had headache, vertigo, nausea and vomiting followed by gait unsteadiness and movement disorders of limbs and eyes. On examination, he had OMS syndrome. Brain MRI, total body scan, MIBG scintigraphy, tumor markers and onconeural antibodies were normal. Cerebro-spinal fluid (CSF) analysis showed lymphocytic meningitis. Positive serum and CSF immunoglobulin M antibody against rubella virus was demonstrated. He received acyclovir with full recovery within two weeks. We discuss the peculiarities of this association with a literature review. This observation enlarges the spectrum of neurological manifestations of rubella as well as that of OMS etiologies.

3D printing plays an increasingly important role in the medical sector and particularly in surgery. Nowadays, numerous manufacturers benefit from this technology to produce their medical devices and some hospitals have also purchased 3D printers. In this context, the aim of the present study was to study the distribution and the use of 3D printing in French hospitals in order to its main features in surgery. By conducting a national survey, we targeted hospitals equipped with 3D printers and those using external providers to benefit from this technology. Forty-seven hospitals were identified as using 3D printing including eight equipped with in-house 3D printers. This work gives us a first picture of 3D printing for hospital use in France and it raises questions about hospital pharmacists' involvement in 3D printed medical device production.

Combining bioinformatics, chemoinformatics and experimental approaches to design chemical probes: Applications in the field of blood coagulation.

PubMed

Villoutreix, B O

2016-07-01

Bioinformatics and chemoinformatics approaches contribute to the discovery of novel targets, chemical probes, hits, leads and medicinal drugs. A vast repertoire of computational methods has indeed been reported over the years and in this review, I will briefly introduce some concepts and approaches, namely the analysis of potential therapeutic target binding pockets, the preparation of compound collections and virtual screening. An example of application is provided for two proteins acting in the blood coagulation system. Overall, in silico methods have been shown to improve R and D productivity in both, academic settings and in the private sector, if they are integrated in a rational manner with experimental approaches. However, integration of tools and pluridisciplinarity are seldom achieved. Efforts should be done in this direction as pluridisciplinarity and a true acknowledgment of all the contributing actors along the value chain could enhance innovation and reduce skyrocketing costs.

2014-06-01

Infection by human parvovirus B19 (erythrovirus B19) is common and usually asymptomatic during childhood conferring lasting protection against a new infection. Parvovirus B19 infection may cause erythema infectiosum (5th disease) and aplastic crisis. Secondary symptomatic parvovirus B19 infection in the same patient is rare and its physiopathology is not always clear. A 48-year-old HIV-infected female patient presented within 5 years two acute episodes of parvovirus B19 infection although her CD4 cells count was above 500/mm(3). Absence of specific antibodies production after the first episode and persisting parvovirus viremia suggested viral reactivation rather than re-infection. During the second episode, specific antibodies were produced. Similarly to most DNA viruses, parvovirus B19 reactivation is possible in HIV-infected patients while effectively treated by antiretroviral therapy.

Listeriosis is a food-borne illness leading to bacteriemia or central nervous system infection especially in pregnant women or high-risk patients. It is rarely a localized infection. Breast contamination has rarely been reported in lactating women. We report a breast abscess in man. A 80 year old man, hypertensive and arrhythmic, was explored for weakness and dehydration. Type 2 diabetes and chronic lymphocytic leukemia were diagnosed. Clinical examination disclosed a breast abcess related to L monocytogenes infection. Histopathological study also revealed a breast subcutaneous infiltration by chronic lymphocytic leukemia. Listeriosis sometimes uncover an unknown immunosuppression, especially in the elderly. Breast is a non-sterile tissue containing a stable microbiome partly from digestive origin. It can thereby be contaminated by Listeria. The specific cutaneous infiltrate of chronic lymphocytic leukemia can create the conditions for a local infection. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

High oxygen affinity hemoglobins.

PubMed

Mangin, O

2017-02-01

High oxygen affinity hemoglobins are responsible for rare and heterogeneous autosomic dominant genetic diseases. They cause pure erythrocytosis, sometimes accountable for hyperviscosity and thrombosis, or hemolysis. Differential diagnoses must be first ruled out. The diagnosis is based on the identification of a decreased P50, and their possible characterization by cation exchange-high performance liquid chromatography and capillary electrophoresis. Finally, genetic studies of the responsible globin chain gene will confirm the mutation. The prognosis mainly relies on the P50 decrease rate and on the hemoglobin cooperativity impairment. Disease management should be personalized, and it should primarily depend on smoking cessation and physical activity. Phlebotomy and platelet aggregation inhibitors' prescriptions can be discussed. There is no contraindication to flights, high-altitude conditions, or pregnancy. Nevertheless, blood donation must be prohibited.

Opportunistic infections (OI) are uncommon in sarcoidosis (1 to 10%) and mostly occur in patients with previously diagnosed disease or can rarely be the presenting manifestation. The most common OIs are, in descending order: aspergillosis, cryptococcosis, and mycobacterial infections. Treatment with corticosteroids is the most frequent risk factor for OI occurrence during sarcoidosis but immunosuppressive drugs and therapy with anti-TNFα are also risk factors. Overall, clinical presentation, treatment, and outcome are identical to that occur in other conditions complicated with the occurrence of OIs. However, some atypical presentations of OIs can mimic sarcoidosis exacerbation and misdiagnosis may lead clinicians to increase immunosuppression, causing worsening of the OI. The meticulous collection of patient's history along with factors differentiating OI from sarcoidosis exacerbation is key factor to optimally manage these patients.

Spontaneous actin dynamics in contractile rings

NASA Astrophysics Data System (ADS)

Kruse, Karsten; Wollrab, Viktoria; Thiagarajan, Raghavan; Wald, Anne; Riveline, Daniel

Networks of polymerizing actin filaments are known to be capable to self-organize into a variety of structures. For example, spontaneous actin polymerization waves have been observed in living cells in a number of circumstances, notably, in crawling neutrophils and slime molds. During later stages of cell division, they can also spontaneously form a contractile ring that will eventually cleave the cell into two daughter cells. We present a framework for describing networks of polymerizing actin filaments, where assembly is regulated by various proteins. It can also include the effects of molecular motors. We show that the molecular processes driven by these proteins can generate various structures that have been observed in contractile rings of fission yeast and mammalian cells. We discuss a possible functional role of each of these patterns.

[Acute pancreatitis as the presenting feature of an IgA vasculitis: An unusual presentation].

PubMed

Fertitta, L; Noel, N; Ackermann, F; Lerolle, N; Benoist, S; Rocher, L; Lambotte, O

2017-10-01

IgA vasculitis is a systemic small vessel leukocytoclastic vasculitis characterized by skin purpura, arthritis, abdominal pain and nephritis. Most of the abdominal complications are due to edema and hemorrhage in the small bowel wall, but rarely to acute secondary pancreatitis. Here, we report a 53-year-old woman who presented with acute pancreatitis and, secondarily, developed skin purpura and arthritis at the seventh day of the clinical onset. Biological tests and computed tomographic scan allowed to rule out another cause of pancreatitis and IgA vasculitis was diagnosed as its etiology. The outcome was favorable without any relapse on glucocorticoids. Despite its rarity, pancreatitis is a potential life-threatening complication of IgA vasculitis in which the role of glucocorticoids and immunosuppressive drugs remains uncertain. A prompt elimination of other usual pancreatitis etiologies is mandatory to improve the management of the patients. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

2016-08-01

In 2015, besides the fact that it still fills the gastroenterologists' offices and impairs patient's quality of life, the irritable bowel syndrome has considerably evolved on several points. The pathophysiology is now organized around a consensual hypothesis called the "brain-gut axis", which gather all the influences of peripheral factors as gut microbiota or local serotonin secretion, on the central pain perception, contributing to visceral hypersensitivity and transit modifications. About the diagnosis, the key message is "avoid over-prescription" of additional tests, and reminds that a positive clinical diagnosis based on Rome III criteria is possible after the elimination of simple clinical warning signs. Finally, the food component, a neglected and historical claim of patients, finally finds a strong scientific rational, with a diet low in fermentable sugar and polyols, that gives positive and reproducible results.

Rapid desensitization allows secure administration of a drug and is indicated when there is no therapeutic alternative. We report a 49-year-old patient who presented with a hypersensitivity reaction following an infusion of rituximab (375mg/m(2)) in the context of a Castleman's syndrome. After a clinical flare (splenomegaly, adenopathies) despite treatment with tocilizumab, anakinra and valganciclovir, the reintroduction of rituximab was decided, according to the rapid desensitization protocol. Four full dose desensitizations were successfully performed allowing immediate clinical improvement (apyrexia, loss of sweating and lymphadenopathy, splenomegaly partial regression) and biological (negativation of HHV8 viral load, and disappearance of neutropenia, anemia and thrombocytopenia). Rapid desensitization is a promising method for the pursuit of rituximab therapy after a hypersensitivity reaction and should be considered in patients with no acceptable therapeutic alternative.

2018-02-01

The most common causes of high anion gap metabolic acidosis (HAGMA) are lactic acidosis, ketoacidosis, and intoxications. Nevertheless, clinicians can be faced with unexplained HAGMA, with a need to look for less common etiologies. We describe a case of 5-oxoproline (pyroglutamate) acidosis due to chronic acetaminophen ingestion at therapeutic dose in a 79-year-old inpatient. The pathophysiology of this condition is detailed, with abnormalities in the gamma-glutamyl cycle due to acetaminophen ingestion and severe chronic morbidities, resulting in glutathione and cysteine deficiency and then accumulation of 5-oxoproline. In HAGMA, when usual causes have been excluded, 5-oxoproline acidosis should be suspected in patients with chronic morbidities and acetaminophen ingestion. This diagnosis should be kept in mind because it generally resolves quickly with cessation of acetaminophen and administration of intravenous fluids.

Posterior reversible encephalopathy syndrome is a clinico-radiological entity characterized by neurologic symptoms in association with usually reversible bilateral posterior hemispheric oedema on neuroimaging. Many pathological conditions and treatments have been associated with this syndrome. We report a 19-year-old woman, followed-up for hypocomplementemic urticarial vasculitis, who presented with a posterior reversible encephalopathy syndrome induced by the intake of an over-the-counter cold remedy containing pseudoephedrine. Clinical manifestations and radiological abnormalities resolved after anti-hypertensive therapy and withdrawal of sympathomimetic drug. The diagnosis of posterior reversible encephalopathy syndrome should be considered in patients with compatible clinical and radiological presentation because of its potential reversibility with an appropriate management. Intake of drugs, including over-the-counter cough and cold drugs, should be looked for in the history as well as autoimmune disorders.

In May 2014, the European Union Parliament and Council published a new regulation on clinical trials on medicinal products for human use, which is designed to replace Directive 2001/20/EC. It will not come into effect until 2016. Nevertheless, it is essential to examine its relationship with national legislation, i.e. the Jardé Act, whose implementation has been delayed pending publication of the European regulation. The Giens workshop identified and examined the various issues that this relationship is bound to raise. In particular, it looked at trial methodology assessment procedures, the working relationship between the French National Agency of Drug Safety and Health Products (Agence Nationale de Sécurité du Médicament et des Produits de Santé, ANSM) and ethics committees during the authorization application evaluation phase, review of post-authorization/registration studies on medicinal products and medical devices, and data transparency. © 2015 Société Française de Pharmacologie et de Thérapeutique.

2013-12-01

Nervous system involvement occurs in 5 to 15% of the patients with sarcoidosis. Neurosarcoidosis remains very difficult to diagnose because clinical presentation and imaging characteristics lack specificity. We report a 26-year-old man who gradually developed headaches, memory disturbance and epilepsy. CT-scan and MRI showed a temporal-parietal cystic mass, secondary to a rare and focal form of hydrocephalus, called "trapped temporal horn" revealing neurosarcoidosis. The "entrapped temporal horn" is due to an obstacle on the cerebrospinal fluid pathway at the trigone of the lateral ventricle that seals off the temporal horn and the choroid plexus from the rest of the ventricular system. The obstacle is related to the granulomatous tissue of sarcoidosis. Therefore, the "trapped temporal horn" acts as a space occupying process, causing headaches, memory pain, hemiparesis, homonymous hemianopsia, and requires medico-surgical management.

Retinal vasculitis (RV) is an inflammation of retinal blood vessels that can be associated with uveitis or be isolated, and can induce vascular occlusion and retinal ischemia. Visual acuity can be severely affected in case of macular involvement or neovessel formation. The diagnosis relies on fundoscopy and fluorescein angiography. Systemic diseases may be associated with RV, the most frequently encountered are Behçet's disease, sarcoidosis or multiple sclerosis, all predominantly associated with venous involvement, whereas systemic lupus erythematosus and necrotizing vasculitis are less frequently observed and predominantly associated with arterial or mixed vasculitis. Treatments are usually aggressive in order to preserve a good visual acuity and to reduce retinal inflammation and chronic ischemia. Steroids, immunosuppressive drugs, retinal laser photocoagulation, intravitreal anti-VEGF injections are usual treatments and more recently, anti-TNFalpha monoclonal therapeutic antibodies have been shown to be very successful.

2012-01-01

In 1997, UNAIDS decided to implement Drug Access Initiatives (DAI) in four different pilot-countries. We studied the implementation of the DAI in Chile as part of the evaluation program conducted by the ‘Agence Nationale de Recherche sur le SIDA’ (ANRS/France). The objective was to understand how the politico-organizational dynamic influenced the implementation process of the DAI. Approximately 50 semi-directed interviews and observation activities were conducted with the actors who participated in the implementation of the DAI or who played a role in the HIV/AIDS context. The program theory models were established and their evolution analyzed. This article offers an original analysis of an international HIV/AIDS drug access program that was put in place at a time when such programs were seen as a priority by international and governmental institutions. It also offers some insights for the creation of international projects that will be locally implemented. PMID:23230344

This paper reports that the French government has decided to slash its direct stake in partly state owned oil company Total to 5% from 31.7%, a surprise move expected to raise 10 billion francs ($1.8 billion). At the same time, other state owned entities will be asked to boost their combined 2.2% stake in Total to 10%, leaving the government with a net 15% interest in Total vs. the current 34%. Initially, state owned insurance companies Groupe des Assurances Nationales and Assurances Generale de France will be asked to hike their stakes in Total, but others could be asked tomore » join if needed to meet the 10% target. The government the its phase-down of participation in Total, established in 1924 to manage French interests in Iraq Petroleum Co., was prompted by the evolution of the oil context, which differs greatly from what had prompted a significant stake of the state in Total's capital.« less

2013-11-01

Multidrug-resistant bacteria are a major worldwide health public concern. It results from the growing increase in antibiotic prescriptions, which are responsible for selection pressure on bacteria. In France like in other countries, enterobacteriaceae producing extended spectrum beta-lactamase (EESBL) are the predominant multidrug-resistant bacteria. EESBL may be responsible for severe infections and require prescription of broad-spectrum antibacterial agents. The current EESBL outbreak is different from methicillin-resistant Staphylococcus aureus outbreak that occurred in the early 1980. Consistently, EESBL are isolated both in hospital and community. Moreover, standard hygiene measures appear ineffective since EESBL prevalence is still increasing. The current inability to contain EESBL outbreak is due to several factors, including the existence of a wide community- and hospital-acquired tank of EESBL, failure to follow strict rules for hygiene, and the current irrational prescription of antibiotics.

2013-01-01

The prevalence of vertebral sarcoidosis is highly variable (1 to 36% of reported case series). Because of limited clinical expression, its frequency is probably underestimated. Its proper management is not clearly defined. A 42-year-old woman who had a past medical history of cutaneous and pulmonary sarcoidosis presented with low back pain that was refractory to usual medical treatment. A diagnosis of vertebral localisation of sarcoidosis was considered on the history of proven sarcoidosis, radiological features, and the absence of evidence of an alternative diagnosis. In the absence of other clinical or biological evidence of active sarcoidosis, a simple follow-up was planned. MRI control at 1 year showed the resolution of vertebral sarcoidosis lesions. Spontaneous regression is a possible outcome of vertebral sarcoidosis. Initiation of a specific treatment should be discussed in the absence of other visceral involvement.

Totally implantable venous access port plays a crucial role in the treatment of patients in oncology. However, its use can result sporadically in catheter fracture with catheter tip embolization into pulmonary arteries. We report this unusual but potentially serious complication in four patients. In these patients, the port had been inserted percutaneously into the subclavian vein using the infra-clavicular approach. This side effect occurred late in three patients. In all patients, the catheter fracture was asymptomatic or pauci-symptomatic and was caused by the pinch-off syndrome. The retrieval of the embolized fragments was successfully performed by transcatheter procedure in the cardiac catheterisation laboratory. We reviewed the literature and the newest guidelines and recommendations to detail the clinico-radiological features, the possible causes of this complication and discussed means to recognize, manage and prevent it.

Large-scale Periodic Variability of the Wind of the Wolf-Rayet Star WR 1 (HD 4004)

NASA Astrophysics Data System (ADS)

Chené, A.-N.; St-Louis, N.

2010-06-01

We present the results of an intensive photometric and spectroscopic monitoring campaign of the WN4 Wolf-Rayet (WR) star WR 1 = HD 4004. Our broadband V photometry covering a timespan of 91 days shows variability with a period of P = 16.9+0.6 -0.3 days. The same period is also found in our spectral data. The light curve is non-sinusoidal with hints of a gradual change in its shape as a function of time. The photometric variations nevertheless remain coherent over several cycles and we estimate that the coherence timescale of the light curve is of the order of 60 days. The spectroscopy shows large-scale line-profile variability which can be interpreted as excess emission peaks moving from one side of the profile to the other on a timescale of several days. Although we cannot unequivocally exclude the unlikely possibility that WR 1 is a binary, we propose that the nature of the variability we have found strongly suggests that it is due to the presence in the wind of the WR star of large-scale structures, most likely corotating interaction regions (CIRs), which are predicted to arise in inherently unstable radiatively driven winds when they are perturbed at their base. We also suggest that variability observed in WR 6, WR 134, and WR 137 is of the same nature. Finally, assuming that the period of CIRs is related to the rotational period, we estimate the rotation rate of the four stars for which sufficient monitoring has been carried out, i.e., v rot = 6.5, 40, 70, and 275 km s-1 for WR 1, WR 6, WR 134, and WR 137, respectively.

Au moment ou dans plusieurs pays on travaille a refondre les programmes d'etudes, tant au primaire qu'au secondaire, l'interet pour le transfert renait. Un des concepts fondamentaux en apprentissage consiste en l'habilete a reutiliser de facon consciente et efficace un acquis d'une situation a une autre situation. Cette recherche emane de preoccupations professionnelles au moment ou le chercheur etait enseignant au secondaire. Au cours de ces annees, il lui a ete possible de constater que plusieurs eleves percevaient difficilement les liens presents entre les disciplines mathematiques et scientifiques. Des travaux en psychologie cognitive et plus particulierement selon une perspective du traitement de l'information ont servi de cadre de reference pour evaluer et analyser les capacites de transfert aupres d'eleves de 4e secondaire. Ce cadre de reference permet de formuler le principal objectif qui est de mieux comprendre le processus de transfert chez des eleves en situation de resolution de problemes scientifiques. Cette these s'interesse donc au transfert en tant que phenomene important du processus d'apprentissage au sens de l'integration. La methode de recherche choisie, de nature qualitative, est principalement axee sur l'evaluation de la capacite a transferer des connaissances lors d'une epreuve et d'un entretien. Pour evaluer ce potentiel de transfert, nous avons elabore deux outils: une epreuve en mathematiques et en sciences et un guide d'entretien. Pour la passation de l'epreuve, le chercheur a pu compter sur la collaboration de 130 sujets provenant de deux ecoles. L'entretien complete la prise de donnees avec 13 sujets ayant accepte de poursuivre l'etude. Les donnees recueillies par ces instruments font ensuite l'objet d'une analyse de contenu. En premier lieu, les verbatims de l'epreuve et de l'entretien ont ete transcrits, puis codifies. La correction des reponses fournies pour les problemes resolus s'est faite a partir d'une grille d

Pantelis, D. I.; Kazasidis, M.; Karakizis, P. N.

2017-12-01

The present study deals with the welding of titanium alloys thin sheets 1.3 mm thick, with the use of concentrated solar energy. The experimental part of the work took place at a medium size solar furnace at the installation of the Centre National de la Recherche Scientifique, at Odeillo, in Southern France, where similar and dissimilar defect-free welds of titanium Grades 4 and 6 were achieved, in the butt joint configuration. After the determination of the appropriate welding conditions, the optimum welded structures were examined and characterized microstructurally, by means of light optical microscopy, scanning electron microscopy, and microhardness testing. In addition, test pieces extracted from the weldments were tested under uniaxial tensile loading aiming to the estimation of the strength and the ductility of the joint. The analysis of the experimental results and the recorded data led to the basic concluding remarks which demonstrate increased hardness distribution inside the fusion area and severe loss of ductility, but adequate yield and tensile strength of the welds.

This paper discusses the galaxy populations of three rich clusters, with redshifts 0.19 (0839+29), 0.24 (1231+15), and 0.32 (1224+20), from the database of the CNOC1 consortium. The data consist of spectra of 52 cluster members for 0839+29, 30 members for 1224+15, and 82 members for 1231+15, and there are comparable numbers of field galaxy spectra. Cluster 0839+29 is compact with no strong radial gradients, and possibly dusty. Cluster 1224+20 is isolated in redshift and has low velocity dispersion around the cD galaxy and low 4000 Å break. Cluster 1231+15 is asymmetric, and we discuss the possibility that it may be a recent merger of two old clusters. We find few galaxies in 0839+29 and 1231+15 with ongoing or recently truncated star formation.

Vallet, M.; Reymonet, N.

Paris Observatory founded in 1667 by Louis XIV is one of the so called "Grand Etablissement" under of the aegis of the Ministry of higher education and research, and includes two other centres: Meudon Observatory and the Radioastronomy centre in Nancay, created respectively in 1876 and 1955. The decree which gave birth to the library itself was signed in 1785 by Louis XVI. In 1926 Meudon is joined to Paris. The total number of bound volumes, including journals, is 100.000. This comprises 2000 periodical titles (of which 1200 are current titles), monographs, photographs, incunabula and manuscripts from the 16th to the 20th century, microfilm versions of historical material. The collections of two libraries are complementary. Starting in 1981, the library became part of a national "Centre d'Acquisition et de Diffusion de l'Information Scientifique et Technique" (CADIST) for astronomy and astrophysics documents. The catalogue is available on national networks such as the Pancatalogue or CCN. It may also be accessed on the international OCLC network. Finally the library may be accessed on internet via WWW.

During summer 1997 experiment 394-018 measured the deuteron tensor polarization in D(e,e'more » $$vec\\{d}$$) scattering in Hall C at Jefferson Laboratory. In a momentum transfer range between 0.66 and 1.8 (GeV=c) 2, with slight changes in the experimental setup, the collaboration performed six precision measurements of the deuteron structure function A(Q 2) in elastic D(e,e'd) scattering . Scattered electrons and recoil deuterons were detected in coincidence in the High Momentum Spectrometer and the recoil polarimeter POLDER, respectively. At every kinematics H(e,e') data were taken to study systematic effects of the measurement. These new precise measurements resolve discrepancies between older data sets and put significant constraints on existing models of the deuteron electromagnetic structure.

BOOK REVIEW: Astronomie von Olbers bis Schwarzschild. Nationale Entwicklungen und internationale Beziehungen im 19. Jahrhundert (Acta Historica Astronomiae Vol. 16)

Sterken, C.; Dick, W. R.; Hamel, J.

2002-12-01

The 14th volume of the Acta Historica Astronomiae is the Proceedings of a Colloquium International Relationships in Astronomy (in German) organised by the History of Astronomy Section of the Astronomische Gesellschaft held on September 18 in Lilienthal, Germany. The book contains 13 articles on astronomical topics covering the 19th and 20th centuries. The first paper is by Guenther Oestmann and deals with contemporary assessments of Johann Hieronymus Schroeter's (1745-1816) astronomical works and with later judgements of the scientific importance and significance of his observations as seen by astronomers and historians. This report is complemented by a second article on Schroeter's 25-ft reflector in Lilienthal near Bremen. To this end, author Felix Luehning has constructed a scale model of the telescope, and shows how the building of a model brings a deeper understanding of function and handling of this instrument. This brings us to a third paper on telescope building in Lilienthal: Hans-Joachim Leue describes the cooperation of Johann Hieronymus Schroeter and Johann Gottlieb Schrader in developing a white reflecting metal alloy for use as telescope mirror. The fourth article, by Klaus Schillinger, describes on the basis of archival documents the aquisition history of the Herschel telescopes, including telescope quality check, repair and building. Memorial sites referring to Wilhelm Olbers, Johann Hieronymus Schroeter, Friedrich Wilhelm Bessel and Carl Friedrich Gauss are described by Arno Langkavel in two walks outlined in the very last paper of this book. Peter Brosche, in the fifth paper, discusses the rediscovery of Ceres in December1801, a discovery that was the result of the combined efforts of a theoretician (Gauss) and an observer (Zach). Juergen Hamel's paper is based on previously unused archival sources and discusses the outstanding role played by H. C. Schumacher (1780-1850, editor of the Astronomische Nachrichten) in the communication between astronomers in his days, when his working place at Altona still belonged to the kingdom of Denmark. This paper is followed by a second one by the same author and deals with the correspondence of H. C. Schumacher and H C. Oersted (1777-1851) and shows how intense and diverse their cooperation was. In a subsequent paper, Wolfgang Kokott describes the role of the Astronomisches Jahrbuch (published from 1776 by the Royal Academy of Sciences at Berlin), a ranking international publication, with Bode's modest Berlin Observatory serving as a clearinghouse of information originating from virtually all European countries. "Karl Schwarzschild and the professionalisation of Astrophysics" is the title of Theodor Schmidt-Kaler's contribution and presents Schwarzschild's contributions to professionalization of astronomy: establishment of course lectures and a permanent astrophysical laboratory, a tight connection between teaching and research, stimulations and suggestions for astronomy at high school and for the formation of high school teachers, international organisation, and the planning of a southern observatory. Peter Habison describes the contribution of Leo de Ball (1853-1916, Director of the Kuffner Observatory in Vienna) to international astronomy. Internationalization in astronomy is also discussed in a following paper by Gudrun Wolfschmidt on the establishment of the Vereinigte Astronomische Gesellschaft, the international Astronomische Gesellschaft in 1863 and finally the International Astronomical Union in 1919. In the second but last paper of the book, Hilmar Duerbeck describes the history of the Chilean National Observatory, beginning with its origins out of Gilliss' US Naval Expedition to the Southern Hemisphere in 1849, over its directors Moesta, Vergara, Obrecht and Ristenpart, to the middle of the 20th century. The paper also includes the astronomical development at the Universidad Catolica and various international expeditions, which aimed at the observations of solar eclipses, the Venus transit of 1882, and the Mars opposition of 1907. An overview of the evolution and the actual state of the international observatories Cerro Tololo, La Silla and Paranal, as well as Las Campanas is also given.

Local responses to French medical imperialism in late nineteenth-century Algeria.

PubMed

Gallois, William

2007-08-01

This article offers the first account of the lives of Algerian-born doctors working in the French colonial medical service between 1870 and 1900. Their stories reveal the manner in which the idea of medical imperialism had collapsed in Algeria, as a result of maladministration, racial policies, competition between civil and military authorities, budgetary constraints and the rise of the colons. The article also indicates the way in which medicine became a locus of opposition to French rule. It shows how the first decades of the Third Republic were critical in terms of a shift from the earlier idea of medicine serving as an emblem of the mission civilisatrice to the ideological potential of medicine being seen in much more nuanced terms by both French settlers and Algerian locals. It is argued that the notion of cultural resistance to imperialism through medicine emerges in the 1870s and 1880s, thereby prefiguring the work of Fanon and the Front de Liberation Nationale's later analysis of the 'sickness' of colonial Algerian society.

A model for evaluating radiological impacts on organisms other than man for use in post-closure assessments of geological repositories for radioactive wastes.

Bioaccumulation and dosimetric models have been developed that allow the computation of dose rates to a wide variety of plants and animals in the context of the deep geological disposal of solid radioactive wastes. These dose rates can be compared with the threshold dose rates at which significant deleterious effects have been observed in field and laboratory observations. This provides a general indication of whether effects on ecosystems could be observable, but does not quantify the level of those effects. To address this latter issue, two indicator organisms were identified and exposure-response relationships were developed for endpoints of potential interest (mortality in conifers and the induction of skeletal malformations in rodents irradiated in utero). The bioaccumulation, dosimetry and exposure-response models were implemented and used to evaluate the potential significance of radionuclide releases from a proposed deep geological repository for radioactive wastes in France. This evaluation was undertaken in the context of a programme of assessment studies being performed by the Agence nationale pour la gestion des déchets radioactifs (ANDRA).

Dupin, N

Syphilis is back since the beginning of this century. The epidemic affects mainly men having sex with men with a high proportion of HIV-infected patients. The classification of syphilis distinguishes early syphilis where patients are contagious (primary, secondary and early latent of less than one year) and late syphilis where patients are not (or less) contagious (late latent of more than one year and tertiary). The clinical presentation of syphilis has not changed. However, we must insist on the early forms of neurosyphilis, notably ophthalmic syphilis often under-diagnosed, as it affects the treatment. Serologic tests may be improved but are very helpful for the positive diagnosis and the follow-up after treatment. Treatment of early syphilis is based on one injection of benzathine benzyl penicillin G. Patients who have had syphilis must be regularly followed-up after treatment, as re-infections are common and are often asymptomatic.

The extraction of information from social media is an essential yet complicated step for data analysis in multiple domains. In this paper, we present Vigi4Med Scraper, a generic open source framework for extracting structured data from web forums. Our framework is highly configurable; using a configuration file, the user can freely choose the data to extract from any web forum. The extracted data are anonymized and represented in a semantic structure using Resource Description Framework (RDF) graphs. This representation enables efficient manipulation by data analysis algorithms and allows the collected data to be directly linked to any existing semantic resource. To avoid server overload, an integrated proxy with caching functionality imposes a minimal delay between sequential requests. Vigi4Med Scraper represents the first step of Vigi4Med, a project to detect adverse drug reactions (ADRs) from social networks founded by the French drug safety agency Agence Nationale de Sécurité du Médicament (ANSM). Vigi4Med Scraper has successfully extracted greater than 200 gigabytes of data from the web forums of over 20 different websites. PMID:28122056

[Enzymes for disrupting bacterial communication, an alternative to antibiotics?

PubMed

Rémy, B; Plener, L; Elias, M; Daudé, D; Chabrière, E

2016-11-01

Quorum sensing (QS) is used by bacteria to communicate and synchronize their actions according to the cell density. In this way, they produce and secrete in the surrounding environment small molecules dubbed autoinducers (AIs) that regulate the expression of certain genes. The phenotypic traits regulated by QS are diverse and include pathogenicity, biofilm formation or resistance to anti-microbial treatments. The strategy, aiming at disrupting QS, known as quorum quenching (QQ), has emerged to counteract bacterial virulence and involves QS-inhibitors (QSI) or QQ-enzymes degrading AIs. Differently from antibiotics, QQ aims at blocking cell signaling and does not alter bacterial survival. This considerably decreases the selection pressure as compared to bactericide treatments and may reduce the occurrence of resistance mechanisms. QQ-enzymes are particularly appealing as they may disrupt molecular QS-signal without entering the cell and in a catalytic way. This review covers several aspects of QQ-based medical applications and the potential subsequent emergence of resistance is discussed. Copyright © 2016 Académie Nationale de Pharmacie.

Pulmonary intravascular talcosis is a rare condition occurring in intravenous drug users injecting oral medications. Talc results in a foreign-body granulomatous reaction giving a radiological haematogenic miliary appearance mimicking miliary tuberculosis. Drug users represent a population at risk for both these conditions and their distinction may be challenging. We reported the case of a man, 33 year-old, intravenous drug addict, detected by the health services because he was the partner of a person who died of contagious and multi-resistant tuberculosis. Chest X-ray and CT scan showed a typical miliary appearance. Despite negative microbiology, clinical diagnosis of miliary tuberculosis was retained. Due to the lack of radiological improvement despite appropriate antibiotic treatment, re-evaluation and trans-bronchial biopsy were undertaken. The presence of granulomas centered by birefringent foreign bodies in polarized light led to a diagnosis of pulmonary intravascular talcosis. In the presence of pulmonary miliary in an intravenous drug addict, intravascular talcosis should be suspected. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

Behçet's disease (BD) is a systemic large-vessel vasculitis characterized by a wide clinical spectrum including recurrent oral and genital ulcerations, uveitis, vascular, neurological, articular, and gastrointestinal manifestations. Therapeutic management of BD depends on the clinical presentation and organ involved. Although colchicine, non-steroidal anti-inflammatory agents and topical treatments with corticosteroids are often sufficient for mucocutaneous and joint involvement, a more aggressive approach with immunosuppressive agents is warranted for severe manifestations such as posterior uveitis, retinal vasculitis, vascular, neurological and gastrointestinal involvement. However, some patients still have refractory disease, relapses, sight threatening eye disease, or irreversible organ damage. Recent improvements in the understanding of the pathogenic mechanisms have led to the identification of potential targets and future therapies for BD. In contrast to current non-specific immunosuppressive agents, the emergence of immunomodulatory drugs provides the possibility of interfering with specific pathogenic pathways. Novel targeted immunosuppressive therapies might be used in the future for BD. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18 FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

Lymphogranuloma venereum (LG) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis L serovar. These five consecutive cases aim to highlight the risk of LG misdiagnosis, in case of initial presentation with isolated inguinal adenitis. Five men (mean age: 30±7 years) were seen in an internal medicine department, for inguinal adenopathy. One patient had clinical signs of urethritis. None presented an associated rectitis. Three patients had a history of STI, and two had a discovery of related HIV disease. Urinary polymerase chain reaction (PCR) was positive for the symptomatic patient and negative for the others. Lymph node PCR was positive in all patients within a L2b serotype (searched in 4 out of 5 cases). LG should be evoked in any patient with inguinal adenomegaly, particularly in case of STI history or risk factors. Negativity of urinary PCR should lead to further investigations, essentially a lymph node cytopuncture to evidence C. trachomatis.

Langerhans cell histiocytosis (LCH) is a rare disease characterized by the infiltration of one or more organs by Langerhans cell-like dendritic cells, most often organized in granulomas. The disease has been initially described in children. The clinical picture of LCH is highly variable. Bone, skin, pituitary gland, lung, central nervous system, lymphoid organs are the main organs involved whereas liver and intestinal tract localizations are less frequently encountered. LCH course ranges from a fulminant multisystem disease to spontaneous resolution. Several randomized controlled trials have enable pediatricians to refine the management of children with LCH. Adult LCH has some specific features and poses distinct therapeutic challenges, knowing that data on these patients are limited. Herein, we will provide an overview of current knowledge regarding adult LCH and its management. We will also discuss recent advances in the understanding of the disease, (i.e. the role of BRAF oncogene) that opens the way toward targeted therapies.

The increasing bacterial resistance to antibiotics has become a major public health concern bringing the threat of therapeutic impasses. In this context, control of the spread of highly-resistant bacteria emerging antibiotics (BHRe), such as glycopeptide-resistant enterococci (VRE) and Enterobacteriaceae producing carbapenemases (CPE), is based on a dual strategy of reducing the prescription of antibiotics to limit the pressure selection and preventing the spread from carriers. Prevention strategy is based on three different levels such as standard precautions for all patients with a particular focus on the management of excreta, and additional precautions for BHRe carriers. What makes it difficult is that carriage is usually completely asymptomatic, enterobacteria and enterococci are normal commensal of gut microbiota. Explosive dissemination of Enterobacteriaceae producing extended spectrum beta-lactamases in hospital and community heralds the emergence of CPE whose import by patients with a history of hospitalization in abroad may be the main source of spread in France.

The favorable season for Aedes albopictus circulation has started in Europe and may lead to autochthonous transmission of Zika virus. Health care providers should be familiar with evocative clinical presentations and able to give updated information to women of reproductive age infected by Zika virus. We report five laboratory-confirmed Zika virus infections imported to metropolitan France from Central and South America between January and April, 2016. The five young women were not connected and not pregnant; common presentation combined a rash with persistent arthralgia. Zika virus was identified by RT-PCR from serum or urines, between two and eight days after the onset of the symptoms. As the duration of potential materno-foetal infectivity is still unknown, we were unable to answer with certitude to the patients' questions about the time interval to respect before attempting a pregnancy: one of them became pregnant one month after the diagnosis.

2012-01-01

One out of four ischemic strokes in France occurs in adults under 65 years old. About a third of them remain unexplained even after an extensive etiological assessment. A large part of these unexplained strokes could be linked to illegal drug abuse, and 10 % are estimated to be directly linked to illegal drugs in some international studies. The most frequently incriminated recreational drug remains cocaine, via several mechanisms. However, several other illegal drugs, some very commonly used such as cannabis, are suspected to have an important role in neurovascular diseases. In this article, we reviewed the epidemiological, pathophysiological and clinical studies, published in the international literature over the past 30 years. The drug-caused stroke epidemiology needs to be more precisely studied, as well as the underlying mechanisms depending on each drug. This is a public health issue that affects an economically active population, as stroke is the first cause of acquired handicap in adults.

The role of biomarkers in clinical research was recently highlighted in the new criteria for the diagnosis of Alzheimer's disease. Cerebro-spinal fluid (CSF) biomarkers (total Tau protein, threonine 181 phosphorylated Tau protein and amyloid Aβ1-42 peptide) are associated with cerebral neuropathological lesions observed in Alzheimer's disease (neuronal death, neurofibrillary tangle with abnormal Tau deposits and amyloid plaque). Aβ1-40 amyloid peptide dosage helps to interpret Aβ1-42 results. As suggested in the latest international criteria and the French HAS (Haute Autorité de santé) recommendations, using theses CSF biomarkers should not be systematic but sometimes could be performed to improve confidence about the diagnostic of Alzheimer's disease in young subjects or in complex clinical situations. Future biomarkers actually in development will additionally help in diagnostic process (differential diagnosis) and in prognostic evaluation of neurodegenerative diseases.

Thrombotic microangiopathies (TMA) represent rare diseases requiring a high skill for their management that deserved in France the identification of a dedicated National reference center. TMA are short-term life-threatening diseases; however, with an adapted management, their prognosis can be excellent. It is therefore mandatory to recognize and treat them rapidly according to standard guidelines. Telemedicine is a specialized hub consisting of highly skilled staff trained in a specific domain of medicine. The telemedicine activity of a reference center is an important representative indicator of its expertise and recourse ability. It requires to be accurately evaluated and promoted. In this work, we report the French reference center for TMA telemedicine activity since its setting-up. TMA represent an interesting model of diseases that required a specific organization of telemedicine activity to adapt to clinicians demand, which includes particularly the need to answer resorts in real time 24/7.

Security and quality of the Medicinal Therapy are one of the most important objectives of the April 6th, 2011 order. The objective is to realize this study of the risks incurred by patients related to management and security of medicinal therapy in order to establish a plan to reduce the risks of drug's dispensation. The method of the Preliminary Risk Analysis (PRA) has been implemented by a multidisciplinary group in a hospital service of orthopaedic surgery. The study focused on the dispensation phase of medicinal circuit. This analysis revealed 148 scenarii, 35 were criticality unacceptable. Fifty-four initial risk control actions were proposed and their stress levels to put them in place were evaluated. The main measures of risk management are: training, information, communication, computerization, automation, dual control, updating the documentation system, drug reconciliation and respect for Best Practices Hospitallers (BPH). Risk management requires a significant human and financial investment as well as, material resources and multidisciplinary expertise in order to offer the best solutions.

Jean Francheteau, pioneering marine geologist and geophysicist, AGU Fellow, and emeritus professor at the University of Brest (Université de Bretagne Occidentale), died on 21 July in St-Renan, Brittany, France, at the age of 67 after a long illness. With his passing, the field of Earth sciences lost a major contributor to the development of a definitive theory of plate tectonics and one of the first to make visual geological observations on the deep seafloor. Such scientific accomplishments, coupled with his personal charm and the ability to collaborate with researchers from many institutions, ensured that he had a huge influence not only on the world of research but also on teaching and the application of ethics to science. Jean arrived at Scripps Institution of Oceanography in La Jolla, Calif., in 1966 after obtaining a diploma in mining engineering at the prestigious Éole Nationale Supérieure de la Métallurgie et de l'Industrie des Mines in Nancy, France. He chose Victor Vacquier as his thesis supervisor and began working in Vic's lab with John Sclater, ostensibly on heat flow measurements.

We propose in this work an efficient way to evaluate the measurement of uncertainty at the end of the development step of an analytical method, since this assessment provides an indication of the performance of the optimization process. The estimation of the uncertainty is done through a robustness test by applying a Placquett-Burman design, investigating six parameters influencing the simultaneous chromatographic assay of five water-soluble vitamins. The estimated effects of the variation of each parameter are translated into standard uncertainty value at each concentration level. The values obtained of the relative uncertainty do not exceed the acceptance limit of 5%, showing that the procedure development was well done. In addition, a statistical comparison conducted to compare standard uncertainty after the development stage and those of the validation step indicates that the estimated uncertainty are equivalent. The results obtained show clearly the performance and capacity of the chromatographic method to simultaneously assay the five vitamins and suitability for use in routine application.

In May 2012, three European Academies held a conference on the present and future of microbiology. The conference, entitled "The New Microbiology", was a joint effort of the French Académie des sciences, of the German National Academy of Sciences Leopoldina and of the British Royal Society. The organizers - Pascale Cossart and Philippe Sansonetti from the "Académie des sciences", David Holden and Richard Moxon from the "Royal Society", and Jörg Hacker and Jürgen Hesseman from the "Leopoldina Nationale Akademie der Wissenschaften" - wanted to highlight the current renaissance in the field of microbiology mostly due to the advent of technological developments and allowing for single-cell analysis, rapid and inexpensive genome-wide comparisons, sophisticated microscopy and quantitative large-scale studies of RNA regulation and proteomics. The conference took place in the historical Palais de l'Institut de France in Paris with the strong support of Jean-François Bach, Secrétaire Perpétuel of the Académie des sciences.

Laminopathies (diseases related to A/C mutations of lamines) are rare genetic diseases with an extensive phenotypic spectrum, including lipodystrophic syndromes-characterized by a selective loss of adipose tissue-of which the partial Dunnigan family type is the most frequent. We report on a 55-year-old woman with diabetes and long-term disabling myalgia. Her cushingoid morphotype, associated with cutaneous lipo-atrophy and muscle hypertrophy in addition to a genetic heritage, led us to the diagnosis of complex partial familial lipodystrophy heterozygous LMNA_c.82C>T, p.Arg28Trp mutation. Familial partial lipodystrophic syndromes may have varied phenotypes, mainly cardio-metabolic, which could mimic a particularly severe type 2 diabetes. The diagnostic work-up of this disease has to include a careful investigation of gait troubles and paroxysmal conduction that could lead to sudden death, as well as a genetic examination. In some cases, recombinant leptin can be proposed. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

To analyse the value of an urology initiation session proposed to young interns to improve recruitment of the discipline since the introduction of the new National-Ranking Exam (NRE). In October 2004, the 77 interns appointed to surgery in Paris on the basis of the ENC participated in a one-day urology initiation session organized by the AFUF, at the AP-HP School of Surgery. All interns were given a questionnaire at the beginning of the session to record the following data: age, gender, teaching hospital, a student attachment in urology and desired specialization as a function of the surgical training programmes proposed by the ENC. Items concerning the desired specialization were resubmitted to the interns at the end of the session. Population. 77 interns, 48 females (62.3%) and 29 males (37.7%) with a mean age of 25.2 +/- 5 years (range: 23-31). 55 interns had trained at a Parisian teaching hospital (67%) and 22 (28.6%) had trained at a provincial teaching hospital. 16 interns (20.8%) had completed at least one urology attachment during their medical training. Desired specialization. Orthopaedics was the discipline most frequently cited (n = 20; 26%). Urology was chosen by 8 interns (10.40%), who had all completed an urology attachment during their medical training. At the end of the urology initiation session, another 8 interns expressed the desire to specialize in urology. Of the 16 potential urology interns, 9 (56.2%) confirmed that their decision was final. Urology occupies a special place and remains a popular surgical speciality among students. Organization of practical sessions constitutes a solution to inform, create an emulation and motivate surgery interns to choose urology.

Origin of the Counterintuitive Dynamic Charge in the Transition-Metal Dichalcogenides

NASA Astrophysics Data System (ADS)

Pike, Nicholas; van Troeye, Benoit; Dewandre, Antoine; Gonze, Xavier; Verstraete, Matthieu

Our recent first-principles calculations of the electronic and vibrational properties of the hexagonal transition-metal dichalcogenides reveal that their Born effective charges display a counterintuitive sign when compared to most other materials or transition-metal dichalcogenides with trigonal symmetry. We determine the origin of this counterintuitive sign by calculating the electronic, vibrational, and optical properties of these systems. We show that the sign of the Born effective charge is directly related to the electric field response of the electronic density, and, in turn, to the bonding characteristics of the material.There is a filled anti-bonding molecular orbital at the Fermi level, which is localized on the transition-metal atom and corresponds to a form of solid state π back-bonding in these material. We propose a method of determining if other materials display a similar counterintuitive sign, based on their bonding characteristics, and propose experiments which could measure the sign of the Born effective charge using different spectroscopies.

Charles Gerhardt's life and work is rather well-known thanks to Grimaux and Tiffeneau. His reform of the equivalents, his classification, his obtention of organic acid anhydrids and his famous Treatise of Organic Chemistry. His active collaboration to the Revue scientifique et industrielle du Docteur Quesneville, the creation of his Comptes-Rendus des Travaux de Chimie. Are not so often quoted. Thanks to his translations and reviews, German chemical advancements became well known in France Gerhardt was Liebig's translator for almost all his life, even through the fluctuations of their personal relation. He was the representative of German chemistry in France. With Auguste Laurent, with whom he is constantly associated, things need to be examined precisely. Laurent and Gerhardt, friends at a moment, cannot be confounded. Though they worked together for some years, they were not engaged in a similar project. Besides an experimentalist, Laurent was essentially a theorician of chemistry, whereas Gerhardt refused to think about atoms and arrangements. Formulas have to describe relations between facts, in no case anything about arrangements. For posterity however, Gerhardt will be, on the same level as Laurent, the creator of modern chemistry doctrines.

The International Year of Astronomy (IYA) in 2009 provides the Adler Planetarium in Chicago, Illinois with a chance to bring astronomy into the city of Chicago and beyond. The Adler serves diverse audiences in the Chicagoland area and elsewhere. Each audience has unique needs to be taken into account when designing for IYA. The Adler has created a suite of programs for IYA that addresses a number of topical strands, tailored for the many audiences that Adler serves. Adler has found synergy between some existing programs designed for these audiences and IYA thematic strands. One advantage of this is that it increases the likelihood of program sustainability. The authors will outline some of Adler's program plans to date from person-to-person community outreach programs such as Café Scientifique programs, to a citizen science light pollution observation program, to programs within the institution, such as a new temporary exhibit about the roles of telescopes in our understanding of the cosmos. The presenters will focus on the range of programming and how they bring together IYA topics as well as addressing the needs of our identified audiences.

RÉSUMÉ L’allaitement exclusif assure une alimentation optimale aux nourrissons jusqu’à l’âge de six mois. Par la suite, les nourrissons ont besoin d’aliments complémentaires pour répondre à leurs besoins nutritionnels. C’est alors que le sevrage commence. Le sevrage désigne le processus graduel d’introduction d’aliments complémentaires au régime du nourrisson, tout en poursuivant l’allaitement. Il n’y a pas de moment universellement accepté ou scientifiquement démontré pour mettre un terme à l’allaitement. Le moment et le processus de sevrage doivent être adaptés par la mère et l’enfant. Le sevrage peut être soudain ou graduel, prendre plusieurs semaines ou plusieurs mois, être dirigé par l’enfant ou par la mère. Les médecins doivent orienter et soutenir les mères tout au long du processus de sevrage. Le présent document remplace le document de principes sur le sevrage qu’a publié la Société canadienne de pédiatrie en 2004.

Facility for assessing spectral normal emittance of solid materials at high temperature.

Spectral emittance is a key topic in the study of new compositions, depositions, and mechanical machining of materials for solar absorption and for renewable energies in general. The present work reports on the realization and testing of a new experimental facility for the measurement of directional spectral emittance in the range of 2.5-20 μm. Our setup provides emittance spectral information in a completely controlled environment at medium-high temperatures up to 1200 K. We describe the layout and first tests on the device, comparing the results obtained for hafnium carbide and tantalum diboride ultrarefractory ceramic samples to previous quasi-monochromatic measurements carried out in the PROMES-CNRS (PROcedes, Materiaux et Energie Solaire- Centre National de la Recherche Scientifique, France) solar furnace, obtaining a good agreement. Finally, to assess the reliability of the widely used approach of estimating the spectral emittance from room-temperature reflectance spectrum, we compared the calculation in the 2.5-17 μm spectral range to the experimental high-temperature spectral emittance, obtaining that the spectral trend of calculated and measured curves is similar but the calculated emittance underestimates the measured value.

Ensemble Classifiers for Predicting HIV-1 Resistance from Three Rule-Based Genotypic Resistance Interpretation Systems.

PubMed

Raposo, Letícia M; Nobre, Flavio F

2017-08-30

Resistance to antiretrovirals (ARVs) is a major problem faced by HIV-infected individuals. Different rule-based algorithms were developed to infer HIV-1 susceptibility to antiretrovirals from genotypic data. However, there is discordance between them, resulting in difficulties for clinical decisions about which treatment to use. Here, we developed ensemble classifiers integrating three interpretation algorithms: Agence Nationale de Recherche sur le SIDA (ANRS), Rega, and the genotypic resistance interpretation system from Stanford HIV Drug Resistance Database (HIVdb). Three approaches were applied to develop a classifier with a single resistance profile: stacked generalization, a simple plurality vote scheme and the selection of the interpretation system with the best performance. The strategies were compared with the Friedman's test and the performance of the classifiers was evaluated using the F-measure, sensitivity and specificity values. We found that the three strategies had similar performances for the selected antiretrovirals. For some cases, the stacking technique with naïve Bayes as the learning algorithm showed a statistically superior F-measure. This study demonstrates that ensemble classifiers can be an alternative tool for clinical decision-making since they provide a single resistance profile from the most commonly used resistance interpretation systems.

Ocular tuberculosis is a rare form of extra pulmonary tuberculosis. It represents 1-2% of all clinical forms. The aim of this work was to focus on diagnostic and therapeutic characteristics of ocular tuberculosis. We report a case series of 14 patients with ocular tuberculosis seen in an infectious diseases department between 2006 and 2015. The diagnosis was retained on clinical data and a positive tuberculin skin test or interferon-gamma release assay. The patient's mean age was 40.7±9years. The most common clinical presentation was uveitis (11 patients and 16 eyes). An extra ocular involvement was associated in three patients. The mean duration of antitubercular therapy was 10±2.5 months. Corticosteroid therapy was associated in 11 cases. The outcome was favorable in all cases. Two patients had maintained visual sequelae. Ocular tuberculosis is a rare disease but still remains a diagnostic problem. It should be considered in case of any chronic ocular symptoms, especially in endemic countries. Early management can improve the visual prognosis. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

2014-06-01

Henoch-Schönlein purpura is a systemic vasculitis of the small vessels characterized by perivascular leucocyte infiltrates. It is an immunoglobulin A-related immune complex-mediated disease involving the skin, the joints and the gastrointestinal system. Renal disease may sometimes be associated to these clinical manifestations. Prevalence of the nephritis is highly variable, depending on the series. More rarely, other organs such as the lungs, the heart or the nervous system may be involved. The clinical diagnosis is confirmed by histopathology of the skin (leukocytoclastic vasculitis) and kidney (endo-capillary proliferative glomerulonephritis), showing IgA deposits in these tissues. Short-term prognosis depends on the severity of digestive involvement, but long-term prognosis depends on the renal disease. Recent publications of pediatric and adult series show that the chronic renal failure may progress, sometimes more than ten years after the initial flare. Treatment is usually supportive. The benefit of more specific treatments (corticosteroids or immunosuppressive drugs) in severe visceral forms (usually abdominal or kidney) has not yet been established.

[The French medecine pricing committee].

Giorgi, D

2017-09-01

The French medicine pricing committee (CEPS) has to reconcile several major constraints, including optimal patient access to medicines and a good control of expenditures on reimbursable medicines. From 2013 to 2015, drug price decreases and discounts obtained by CEPS contributed more than € 5 billion to the balance of the health insurance accounts. As for price setting, there is a significant drop in the prices of medicines in France once they are registered for reimbursement. France is affected by a limited, but costly, flow of innovative medicines, whose prices are higher than those of previous generations, a reflection of an international gradient to which France is obviously subject, despite prices that remain at the low end of the range in Western Europe. The provision of innovative medicines for all patients who need them has been ensured in France over the last fifteen years at a controlled cost. But with the arrival of new expensive products, a resolute policy of control of expenditures must take over from the fall in prices, and original financing channels will have to be explored.

[Repetitive transcranial magnetic stimulation: A potential therapy for cognitive disorders?

PubMed

Nouhaud, C; Sherrard, R M; Belmin, J

2017-03-01

Considering the limited effectiveness of drugs treatments in cognitive disorders, the emergence of noninvasive techniques to modify brain function is very interesting. Among these techniques, repetitive transcranial magnetic stimulation (rTMS) can modulate cortical excitability and have potential therapeutic effects on cognition and behaviour. These effects are due to physiological modifications in the stimulated cortical tissue and their associated circuits, which depend on the parameters of stimulation. The objective of this article is to specify current knowledge and efficacy of rTMS in cognitive disorders. Previous studies found very encouraging results with significant improvement of higher brain functions. Nevertheless, these few studies have limits: a few patients were enrolled, the lack of control of the mechanisms of action by brain imaging, insufficiently formalized technique and variability of cognitive tests. It is therefore necessary to perform more studies, which identify statistical significant improvement and to specify underlying mechanisms of action and the parameters of use of the rTMS to offer rTMS as a routine therapy for cognitive dysfunction.

2016-02-01

Sickle cell patients in acute pain situation experiment cognitive, behavioral and emotional changes that can accentuate their pain and disrupt communication with caregivers. On the other hand, caregivers have to face pain assessment difficulties and their own psychological reactions to their patient's pain. The gap between the patient's experience and caregiver's evaluation can lead to conflict and non-adherence treatment, and have a direct impact on the sickle cell disease prognosis. There is nothing inevitable about these phenomena, whose knowledge allows the action and opens up prospects for improving the management of sickle cell disease pain. This article is a narrative review updating the interactions between acute pain and some configurations, such as the inability to discern emotions, catastrophizing, post-traumatic stress or feeling ostracized. The overestimation of patient's addiction by caregivers also influences the pain itself. Open communication, as well as some treatments, medicated or not, a consistent institutional organization and a multidisciplinary approach altogether have an analgesic role by acting on pain cognitive and emotional components.

Improving influenza vaccination coverage has been, and still remains a challenge internationally. There are now many examples where countries have pursued a pharmacist-led influenza vaccination service in order to enhance vaccination coverage of at-risk populations. England, Portugal and the United States are successful examples where their experience implementing this service can now be explored retrospectively and learnt from. This review aims to provide evidence to help overcome barriers to commissioning and implementation of such services in countries new to the experience. Implementation is influenced by differing regulatory frameworks underpinning the provision of pharmacist-led influenza vaccination, methods of remuneration, training, and operating procedures. Practical aspects such as the facilities required, how patient records are maintained and how patients and other healthcare professionals are engaged also have an impact. These examples illustrate how community pharmacists can be trained to deliver influenza vaccinations safely, and coupled with their accessibility and convenience, can provide a complementary service to that already provided by family doctors and nurses to deliver influenza vaccinations for the benefit of patients.

Splenic abscess is septic collection which occurs after haematogenous spread or local dissemination. Splenic abscess is an uncommon and rare condition, more frequently affecting male and immunocompromised patients. There are no guidelines regarding its diagnosis and management. Computed tomography (CT) scan is highly sensitive and specific (95% and 92%, respectively) in the diagnosis of splenic abscess. Diagnosis is based on blood cultures which are positive in 24 to 80% of cases. Bacterial growth culture of abscess after drainage is more efficient (50-80%) and can be performed after surgery or percutaneous drainage under imaging, including CT scan. Microorganisms involved are frequently enterobacteriaceae, gram-positive cocci and anaerobes. This particular ecology leads to an empiric broad-spectrum antibiotic therapy, with a variable duration, from 10days to more than one month. Management remains very close to the one applied in case of liver abscesses. The role of splenectomy in the prevention of recurrence remains controversial. We reviewed the literature regarding splenic abscesses, from diagnosis to therapy. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS.

The Groupe de Pédiatrie Générale (General Pediatrics Group), a member of the Société française de pédiatrie (French Pediatrics Society), has proposed guidelines for families and doctors regarding children's use of digital screens. A number of guidelines have already been published, in particular by the French Academy of Sciences in 2013 and the American Academy of Pediatrics in 2016. These new guidelines were preceded by an investigation into the location of digital screen use by young children in France, a survey of medical concerns on the misuse of digital devices, and a review of their documented benefits. The Conseil Supérieur de l'Audiovisuel (Higher Council on Audiovisual Technology) and the Union Nationale de Associations Familiales (National Union of Family Associations) have taken part in the preparation of this document. Five simple messages are proposed: understanding without demonizing; screen use in common living areas, but not in bedrooms; preserve time with no digital devices (morning, meals, sleep, etc.); provide parental guidance for screen use; and prevent social isolation.

The International Conference on Heavy Ion Collisions in the LHC Era was held in Quy Nhon, Vietnam, on 16-20 July 2012. The series Rencontres du Vietnam, created by Jean Tran Thanh Van in 1993, consists of international meetings aimed to stimulate the development of advanced research in Vietnam and more generally in South East Asia, and to establish collaborative research networks with Western scientific communities. This conference, as the whole series, also supports the International Center for Interdisciplinary Science Education being built in Quy Nhon. The articles published in this volume present the latest results from the heavy-ion collision programs of RHIC and LHC as well as the corresponding theoretical interpretation and future perspectives. Lower energy nuclear programs were also reviewed, providing a rather complete picture of the state-of-the-art in the field.

FRIPON (Fireball Recovery and InterPlanetary Observation Network) [4](Colas et al, 2014) was recently founded by ANR (Agence Nationale de la Recherche). Its aim is to connect meteoritical science with asteroidal and cometary science in order to better understand solar system formation and evolution. The main idea is to set up an observation network covering all the French territory to collect a large number of meteorites (one or two per year) with accurate orbits, allowing us to pinpoint possible parent bodies. 100 all-sky cameras will be installed at the end of 2015 forming a dense network with an average distance of 100km between stations. To maximize the accuracy of orbit determination, we will mix our optical data with radar data from the GRAVES beacon received by 25 stations [5](Rault et al, 2015). As both the setting up of the network and the creation of search teams for meteorites will need manpower beyond our small team of professionals, we are developing a citizen science network called Vigie-Ciel [6](Zanda et al, 2015). The public at large will thus be able to simply use our data, participate in search campaigns or even setup their own cameras.

Effect of the band structure in a rigorous two-body model with long-range interactions in 1D optical lattices

NASA Astrophysics Data System (ADS)

Kristensen, Tom; Simoni, Andrea; Launay, Jean-Michel

2016-05-01

We compute scattering and bound state properties for two ultracold molecules in a pure 1D optical lattice. We introduce reference functions with complex quasi-momentum that naturally account for the effect of excited energy bands. Our exact results for a short-range interaction are first compared with the simplest version of the standard Bose-Hubbard (BH) model. Such comparison allows us to highlight the effect of the excited bands, of the non-on-site interaction and of tunneling with distant neighbor, that are not taken into account in the BH model. The effective interaction can depend strongly on the particle quasi-momenta and can present a resonant behavior even in a deep lattice. As a second step, we study scattering of two polar particles in the optical lattice. Peculiar Wigner threshold laws stem from the interplay of the long range dipolar interaction and the presence of the energy bands. We finally assess the validity of an extended Bose-Hubbard model for dipolar gases based on our exact two-body calculations. This work was supported by the Agence Nationale de la Recherche (Contract No. ANR-12-BS04-0020-01).

ANDRA is in charge of design, siting, construction, and operation of disposal centers. The solution selected in France for the disposal of low- and medium-level, short-lived radioactive waste is near-surface disposal in the earth using the principle of multiple barriers, in accordance with national safety rules and regulations, and based on operating experience from the Centre de Stockage de la Manche. Since the center's start-up in 1969, 400,000 m{sup 3} of waste have been disposed of. The Frenchmore » national program for waste management is proceeding with the construction of a second near-surface disposal, which is expected to be operational in 1991. It is located in the department of AUBE (from which its name derives), 100 miles southeast of Paris. The paper describes the criteria for siting and design of the AUBE disposal facility, design of the AUBE facility disposal module, and comparison with North Carolina and Pennsylvania disposal facility designs.« less

Identify the training profile and the published evidences about the roles and the impacts of hospital pharmacists in medical devices. A literature review was conducted using Google, Google Scholar and Pubmed for 1990-2016 associated with a manual search conducted in three non-indexed pharmaceutical journals for 2000-2016. The analysis of training programs available did not allow us to identify a specific training profile. A total of 72 articles related to the roles and the impacts of the pharmacist were identified, 52 of which came from non-indexed journals. Those articles did not deal specifically about the roles and the impacts of pharmacist; however, articles were analyses for three spheres including the referencing of medical devices (n=36), the evaluation (n=19) and the distribution system (n=13). French pharmacists have many theoretical and practical training opportunities. There are a few articles describing precisely the roles and the impacts of hospital pharmacists in medical device. It appears urgent to better document this activity in professional and indexed literature. Copyright © 2017 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS. All rights reserved.

Né simultanément à Mulhouse et à Beyrouth en 1996 dans le cadre d'une collaboraiion franco-libanaise sur une initiative personnelle de Monsieur Tayssir HAMIEH. le Colloque Franco-Libanais sur la Science des Matériaux (CSM), qui s'inscrit dans le cadre des relations étroites entre la France et le Liban, est très vite devenu une occasion très importante de rencontre entre scientifiques de haut niveau, non seulement, du contour méditerranéen mais également des pays européens, américains et arabes. La quatrieme édition CSM4 est une véritable réussite grâce à la participation des chercheurs confirmés dans tous les domaines des sciences de matériaux et venant de plusieurs pays tels que la France, I'Algérie, Le Liban, la Syrie, le Maroc, la Tunisie, l'Italie, l'Espagne, le Portugal, le Royaume Uni, les États-Unis, la Russie, l'Allemagne, le Japon et I'Inde ; pour présenter plus de 350 communications orales et par affiche et couvrant presque toutes les disciplines des systèmes des matériaux. Le choix des diffèrents thèmes du colloque sur la science des matériaux a été dicté par l'importance capitale de cette discipline dans notre civilisation moderne. En fait, les matériaux utilisés pour la fabrication artisanale ou industrielle d'objets, de produits et de systèmes ainsi que pour la réalisation de constructions et d'équipements ont de tout temps défini le niveau de notre civilisation technique. La réalisation des objectifs communs de notre monde en plein développement, pour ne pas dire en pleine mutation, est en grande partie tributaire de la mise au point de nouveaux matériaux et de procédés de transformation et d'assemblages nouveaux, présentant des performances et des qualités améliorées. Le colloque a illustré et traduit, de manière remarquables, l'excellente collaboration entre chercheurs libanais et français. Le partenariat est exemplaire par la qualité des laboratoires impliqués et par le niveau scientifique des r

A study on the relationship between the ANDEM--Agence Nationale pour le Développement de l'Evaluation Médicale (French agency for the development of health technology assessment) and the learned societies showed that a definition of the role of these organisations and criteria to define learned societies were lacking. We conducted a survey among the learned societies in the field of medicine so as to elaborate a definition. We used the files of the learned societies of the Anaes--Agence Nationale d'Accréditation et d'Evaluation en Santé (French Agency for accreditation and evaluation in health) in 1998, which included 225 organisations. We sent a letter together with a single-page questionnaire and copies of the 2 publications on the relationship between the ANDEM and the learned societies. To analyse the suggestions for a definition, having read the replies, a segmentation of the population, the means and modalities of action and the aims and fields of action were used. A proposal for a definition was discussed during 2002/2003 with the board of the Fédération des Spécialités Médicales (FSM) (Federation of medical specialties) regrouping 33 medical and 12 surgical societies. Three meetings between a representative of the Anaes and the board of the FSM resulted in the proposition of so-called "validation" criteria for learned societies. A search on the French Internet listing such societies was made using a research motor (March 20, 2004). Out of the 225 organisations contacted, 129 (57%) replied. Among the latter, 115 considered themselves as a learned society and 14 did not. Among the 115 organisations defining themselves as a learned society, 97 proposed a definition, 16 made use of the definitions proposed in the questionnaire and 81 proposed their own definition. The analysis identified 6 important elements (reporting, knowledge, education, research, diffusion, promotion). The data analysed permitted the elaboration of a definition based on the

La présente analyse bibliographique a pour objectif de réaliser un bilan des travaux publiés dans le champ de la douleur et de l’autisme. L’article aborde, dans un premier temps, les études publiées concernant les modes d’expression de la douleur observés dans cette population. Différentes hypothèses permettant d’expliquer les particularités expressives des personnes avec autisme sont ensuite passées en revue : excès d’endorphines, particularités dans le traitement sensoriel, déficit sociocommunicatif. Cette analyse bibliographique aborde, pour terminer, la question de l’évaluation et de la prise en compte de la douleur chez les personnes avec autisme. Les auteurs concluent à l’absence d’homogénéité des résultats des études publiées et au besoin de poursuivre les recherches afin de parvenir à des données consensuelles sur un domaine d’étude encore peu exploité au plan scientifique. Sur un plan clinique, l’approfondissement des connaissances dans ce domaine devrait permettre de mettre au point des outils d’évaluation de la douleur et d’ainsi en assurer une meilleure prise en charge au quotidien.

ARAT (Avion de Recherche Atmosphérique et de Télédétection), is owned and operated by IGN (Institut Géographique National) and managed by INSU, an institute of CNRS (Centre National de la Recherche Scientifique). ARAT is a versatile flying laboratory offering several scientific configurations: basic meteorological instrumentation, turbulent flux equipment, radiation measurement (Visible, Red, IR, UV, J(NO_2), radiance, ground temperature), microphysics sensors, in-situ and remote sensing chemistry instruments (NO-NO_2-NOy and PAN, Water Vapour and Ozone Lidars), Aerosol Lidar, Earth Observation Instrumentation (Visible, Microwave, POLDER), etc. Access to ARAT was offered through the EC-funded IHP-ARI contract, under a co-ordinated aircraft project (with MRF, U.K.; DLR, Germany and Meteo France) called CAATER (Co-ordinated Access to Aircraft for Transnational Environmental Research). Since 2000 access to ARAT has been offered to 6 research groups from different EU Member States for about 10 flight hours each. This project is a follow-on to STAAARTE (1996-2000), which gave access to ARAT to 14 user groups for about 8 flight hours per group. A new project, with new aircraft, within the frame of an Integrated Infrastructure Initiative of the Sixth Framework Programme is currently in preparation.

Follow-up of a report of a potential linkage for schizophrenia on chromosome 22q12-q13.1: Part 2

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pulver, A.E.; Lasseter, V.K.; Wolyniec, P.

A collaboration involving four groups of investigators (Johns Hopkins University/Massachusetts Institute of Technology; Medical College of Virginia/The Health Research Board, Dublin; Institute of Psychiatry, London/University of Wales, Cardiff; Centre National de la Recherche Scientifique, Paris) was organized to confirm results suggestive of a schizophrenia susceptibility locus on chromosome 22 identified by the JHU/MIT group after a random search of the genome. Diagnostic, laboratory, and analytical reliability exercises were conducted among the groups to ensure uniformity of procedures. Data from genotyping of 3 dinucleotide repeat polymorphisms (at the loci D22S268, IL2RB, D22S307) for a combined replication sample of 256 families, eachmore » having 2 or more affected individuals with DNA, were analysed using a complex autosomal dominant model. This study provided no evidence for linkage or heterogeneity for the region 22q12-q13 under this model. We conclude that if this region confers susceptibility to schizophrenia, it must be in only a small proportion of families. Collaborative efforts to obtain large samples must continue to play an important role in the genetic search for clues to complex psychiatric disorders such as schizophrenia. 32 refs., 3 tabs.« less

On the performance of updating Stochastic Dynamic Programming policy using Ensemble Streamflow Prediction in a snow-covered region

Martin, A.; Pascal, C.; Leconte, R.

2014-12-01

Stochastic Dynamic Programming (SDP) is known to be an effective technique to find the optimal operating policy of hydropower systems. In order to improve the performance of SDP, this project evaluates the impact of re-updating the policy at every time step by using Ensemble Streamflow Prediction (ESP). We present a case study of the Kemano's hydropower system on the Nechako River in British Columbia, Canada. Managed by Rio Tinto Alcan (RTA), this system is subject to large streamflow volumes in spring due to important amount of snow depth during the winter season. Therefore, the operating policy should not only maximize production but also minimize the risk of flooding. The hydrological behavior of the system is simulated with CEQUEAU, a distributed and deterministic hydrological model developed by the Institut national de la recherche scientifique - Eau, Terre et Environnement (INRS-ETE) in Quebec, Canada. On each decision time step, CEQUEAU is used to generate ESP scenarios based on historical meteorological sequences and the current state of the hydrological model. These scenarios are used into the SDP to optimize the new release policy for the next time steps. This routine is then repeated over the entire simulation period. Results are compared with those obtained by using SDP on historical inflow scenarios.

Role of Elasto-Inertial Turbulence in Polymer Drag Reduction

NASA Astrophysics Data System (ADS)

Dubief, Yves; Sid, Samir; Terrapon, Vincent

2017-11-01

Elasto-Inertial Turbulence (EIT) is a peculiar state of turbulence found in dilute polymer solutions flowing in parallel wall flows over a wide range of Reynolds numbers. At subcritical Reynolds numbers, appropriate boundary conditions trigger EIT, a self-sustaining cycle of energy transfers between thin sheets of stretched polymers and velocity perturbations, which translates into an increase of friction drag. For critical and supercritical Reynolds numbers, polymer additives may lead to significant drag reduction, bounded by the asymptotic state known as Maximum Drag Reduction (MDR). The present research investigates the role of EIT in the dynamics of critical and supercritical Reynolds number wall flows. Using high-fidelity direct numerical simulations of channel flows and the FENE-P model, we establish that (i) EIT is two-dimensional, (ii) the scales essential to the existence of EIT are sub-Kolmogorov, and (iii) EIT drives MDR at low and possibly moderate Reynolds number turbulent flows. These findings were validated in two different codes and using unprecedented resolutions for polymer flows. YD is grateful for the support of Binational Science Foundation.

Deficiency of adenosine deaminase 2 (DADA2) is a recently described auto-inflammatory disorder. It is an autosomal recessive inherited disease, caused by mutations in the ADA2 gene (formerly known as CECR1) encoding ADA2 enzyme. Besides its role in the purine metabolism, it has been postulated that ADA2 may act as a growth factor for endothelial cells and in the differenciation of monocytes. Thus, deficiency of ADA2 would lead to endothelial damage and a skewing of monocytes into M1 pro-inflammatory macrophage, causing DADA2 manifestations. Three core clinical features have been described: inflammatory-vascular signs, hematologic abnormalities and immunodeficiency. Clinically, patients display intermittent fever, cutaneous vascular manifestations, such as livedo, ischemic strokes, arthralgia and abdominal pain crisis. Corticosteroids and immunosuppressive agents (i.e. cyclophosphamide, azathioprine, ciclosporin, methotrexate) appear to be poorly effective. Although the mechanism has not been elucidated, anti-TNF agents have been proven efficient in DADA2 and should therefore be used as first line therapy for vasculitis. Role of anti-platelet and anticoagulant therapies in stroke-prophylaxis remains to be discussed, as those patients display a high risk of intracranial bleeding.

Costless Platform for High Resolution Stereoscopic Images of a High Gothic Facade

In October 2011, the PPMD specialized master's degree students (Photogrammetry, Positionning and Deformation Measurement) of the French ENSG (IGN's School of Geomatics, the Ecole Nationale des Sciences Géographiques) were asked to come and survey the main facade of the cathedral of Amiens, which is very complex as far as size and decoration are concerned. Although it was first planned to use a lift truck for the image survey, budget considerations and taste for experimentation led the project to other perspectives: images shot from the ground level with a long focal camera will be combined to complementary images shot from what higher galleries are available on the main facade with a wide angle camera fixed on a horizontal 2.5 meter long pole. This heteroclite image survey is being processed by the PPMD master's degree students during this academic year. Among other type of products, 3D point clouds will be calculated on specific parts of the facade with both sources of images. If the proposed device and methodology to get full image coverage of the main facade happen to be fruitful, the image acquisition phase will be completed later by another team. This article focuses on the production of 3D point clouds with wide angle images on the rose of the main facade.

[Management of neuropathic pain].

Lozeron, P; Kubis, N

2015-07-01

Neuropathic pain is often underestimated and not adequately treated. The DN4 scale is very useful for its identification since it will benefit from pharmacological and non-pharmacological specific alternative care. The pathophysiological mechanisms involve the hyperexcitability of nociceptive pathways or decreased inhibitory descending controls that will be the target of pharmacological treatments. Frontline molecules are antidepressants (tricyclics and mixed serotonin and norepinephrine reuptake inhibitors) and antiepileptics (α2δ calcium channel inhibitors). However, these drugs will only have a partial efficacy on pain. The therapeutic strategy is based on reasonable goals, starting with a monotherapy adapted to the patient's symptoms and comorbidities and increased step by step. Patient compliance to contract is essential and requires clear and complete information. The impact on profession, social and family integration should rapidly be taken into account. In case of inefficiency, a change of the first-line treatment or an association could be considered. Some indications justify a specific therapy. Patients with resistant chronic pain should be sent to a specialized centre. New drugs are being studied and non-pharmacological support must be evaluated.

Eye involvement in Behçet's disease (BD) is frequent and an important cause of morbidity. The mean age at onset of uveitis is between 20 and 30 years in male and 30 years in female patients. Ocular involvement includes anterior, posterior or panuveitis. Uveitis may be the presenting manifestation of the disease in 20% of cases or may appear 2 or 3 years after the disease onset. The estimated risk of blindness at 5 years ranges from 15 to 25%. The main goals in the management of patients with BD uveitis are the rapid control of intraocular inflammation, the prevention of recurrent attacks, the achievement of complete remission, and preservation of vision. The medical treatment of patients with severe uveitis relies on the use of systemically administered drugs, including corticosteroids and cytotoxic agents. Anti-TNF agents and interferon-alpha seem to be efficient and well-tolerated alternative therapeutic options. Controlled clinical trials are mandatory to define the place of these new immunomodulatory agents in the therapeutic strategy, and especially their use as first-line therapy.

[Management of mesenteric ischemia in the era of intestinal stroke centers: The gut and lifesaving strategy].

PubMed

Nuzzo, A; Corcos, O

2017-09-01

Mesenteric ischemia is a gut and life-threatening, medical and surgical, digestive and vascular emergency. Mesenteric ischemia is the result of an arterial or venous occlusion, a vasospasm secondary to low-flow states in intensive care patients, aortic clamping during vascular surgery or intestinal transplantation. Progression towards mesenteric infarction and its complications is unpredictable and correlates with high rates of mortality or a high risk of short bowel syndrome in case of survival. Thus, mesenteric ischemia should be diagnosed and treated at an early stage, when gut injury is still reversible. Diagnostic workup lacks sensitive and specific clinical and biological marker. Consequently, diagnosis and effective therapy can be achieved by a high clinical suspicion and a specific multimodal management: the gut and lifesaving strategy. Based on the model of ischemic stroke centers, the need for a multidisciplinary and expert 24/24 emergency care has led, in 2016, to the inauguration of the first Intestinal Stroke Center (Structure d'urgences vasculaires intestinales [SURVI]) in France. This review highlights the pathophysiological features of chronic and acute mesenteric ischemia, as well as the diagnosis workup and the therapeutic management developed in this Intestinal Stroke Center.

To secure medical devices' management, the implementation of automated dispensing system in surgical service has been realized. The objective of this study was to evaluate security, organizational and economic impact of installing automated dispensing system for medical devices (ASDM). The implementation took place in a cardiac surgery department. Security impact was assessed by comparing traceability rate of implantable medical devices one year before and one year after installation. Questionnaire on nurses' perception and satisfaction completed this survey. Resupplying costs, stocks' evolution and investments for the implementation of ASDM were the subject of cost-benefit study. After one year, traceability rate is excellent (100%). Nursing staffs were satisfied with 87.5% by this new system. The introduction of ASDM allowed a qualitative and quantitative decrease in stocks, with a reduction of 30% for purchased medical devices and 15% for implantable medical devices in deposit-consignment. Cost-benefit analysis shows a rapid return on investment. Real stock decrease (purchased medical devices) is equivalent to 46.6% of investment. Implementation of ASDM allows to secure storage and dispensing of medical devices. This system has also an important economic impact and appreciated by users.

Juvenile dermatomyositis is the leading cause of chronic idiopathic inflammatory myopathy of auto-immune origin in children. Lung involvement in inflammatory myopathies is well described in adults, involving mostly interstitial lung disease, aspiration pneumonia and alveolar hypoventilation. We propose to describe its specificities in children. Pulmonary involvement may be asymptomatic and therefore must be systematically screened for. In case of clinical or functional respiratory abnormality, a chest computed tomographic (CT) scan is necessary. In children, a decrease of respiratory muscle strength seems common and should be systematically and specifically searched for by non-invasive and reproducible tests (sniff test). Interstitial lung disease usually associates restrictive functional defect, impairment of carbon monoxide diffusion and interstitial lung disease on CT scan. As in adults, the first-line treatment of juvenile dermatomyositis is based on corticosteroids. Corticosteroid resistant forms require corticosteroid bolus or adjuvant immunosuppressive drugs (methotrexate or cyclosporine). There is no consensus in pediatrics for the treatment of diffuse interstitial lung disease. Complications of treatment, including prolonged steroid therapy, are frequent and therefore a careful assessment of the treatments risk-benefit ratio is necessary, especially in growing children.

PubMed

Dinh, A; Bouchand, F; Le Monnier, A

2015-09-01

During the past 10years, Clostridium difficile infections (CDI) have become a major public health challenge. Their epidemiology has changed with a rise in the number of cases and an increase in severe episodes. Recurrence and failure of conventional treatments have become more common. Furthermore, a spread of CDI has been observed in the general population-involving subjects without the usual risk factors (unexposed to antibiotic treatment, young people, pregnant women, etc.). All these change are partially due to the emergence of the hypervirulent and hyperepidemic clone NAP1/B1/027. New therapeutic strategies (antimicrobial treatment, immunoglobulins, toxin chelation, fecal microbiota transplantation) are now available and conventional treatments (metronidazole and vancomycin) have been reevaluated with new recommendations. Recent studies show a better efficacy of vancomycin compared to metronidazole for severe episodes. Fidaxomicin is a novel antibiotic drug with interesting features, including an efficacy not inferior to vancomycin and a lower risk of recurrence. Finally, for multi-recurrent forms, fecal microbiota transplantation seems to be the best option. We present the available data in this review.

The PASS ("Permanence d'Accès aux Soins de Santé") are hospital-based units providing primary care services to patients who lack health care coverage. Using a "whole person" approach and providing a combination of health and social care, the PASS offer an appropriately adapted response to complex health problems within a context of marked social vulnerability and contribute to reducing health inequalities. The PASS are an example of an interdisciplinary approach to health care which contrasts with the segmentary approach typical of conventional hospital departments. Operating at the interface between primary and secondary care, the PASS have the potential to become key players in developing models of patient pathways. Their presence reduces inappropriate emergency attendances and hospitalisation by offering medical care in a timely fashion, in an outpatient-type setting. The PASS can provide a resource for research into optimum models of health care, where the social context of health needs are fully recognized and inform medical treatment appropriately. According to their potential development, PASS are living labs of an innovative organizational model of care. Copyright © 2014 Société nationale française de médecine interne (SNFMI).

This study aims to investigate the stability of florfenicol using previously developed derivative spectrophotometric methods (D 1 and D 2 ). The studied stability-indicating pararmeters included alkali (NaOH, 1M), acid (HCl, 1M), pH changes (buffer pH 2.2-11), temperature (80°C and 100°C at pH 10) and light. A constructed pH profile for the drug degradation rate revealed a significant effect of pH on the drug stability between pH ranges 8 and 11. The obtained profile indicated first order dependence of K obs on [OH - ]. Arrhenius plot at pH 10 was found linear at temperatures 80°C and 100°C with estimated activation energy of 19.35kcal/mol. The calculated rate constant (K obs ), t ½ and t 90 at 25°C were found to be 1.8×10 -3 h, 385h and 58.3h, respectively. The photostability of florfenicol was also studied by exposing the drug solution to direct sunlight during mid-day time. The obtained results reflected the instability of florfenicol under the study conditions. Copyright © 2016 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS. All rights reserved.

2015-01-01

Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament), the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP) breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof) of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France). The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse) were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%), infection (22.2%), and capsular contracture (13.6%). Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel.

HPLC & NMR-based forced degradation studies of ifosfamide: The potential of NMR in stability studies.

The aim of this study is to conduct a forced degradation study on ifosfamide under several stress conditions to investigate the robustness of the developed HPLC method. It also aims to provide further insight into the stability of ifosfamide and its degradation profile using both HPLC and NMR. Ifosfamide solutions (20mg/mL; n=15, 20mL) were stressed in triplicate by heating (70°C), under acidic (pH 1 & 4) and alkaline (pH 10 & 12) conditions. Samples were analysed periodically using HPLC and FT-NMR. Ifosfamide was most stable under weakly acidic conditions (pH 4). NMR results suggested that the mechanism of ifosfamide degradation involves the cleavage of the PN bond. For all stress conditions, HPLC was not able to detect ifosfamide degradation products that were detected by NMR. These results suggest that the developed HPLC method for ifosfamide did not detect the degradation products shown by NMR. It is possible that degradation products co-elute with ifosfamide, do not elute altogether or are not amenable to the detection method employed. Therefore, investigation of ifosfamide stability requires additional techniques that do not suffer from the aforementioned shortcomings. Copyright © 2015 Académie Nationale de Pharmacie.

The aim of this study is to make an assessment of the presence of particles during the manipulation of glass ampules and to discuss the current practices. Literature review based on a search strategy (Pubmed, Google Scholar) and a summary table of available data. Analysis to evaluate the efficacy of the filtration when data are available. Eighteen articles have been included. Most of study shows the presence of particles in glass ampules. Important discrepancies reported regarding the number of particles per ampule. Analysis of data from seven studies: decrease of 83% of the total number of particles (>10μm) identified when drugs are removed with filter needle. All studies but two confirm the efficacy of filter needles. Studies show the presence of particles when drugs are removed from glass ampules. They do not allow to make a conclusion on human clinical consequences associated with the presence of particles. It is necessary to evaluate in human the risks associated with particle contamination to determine the optimal use of filter needle. Copyright © 2017 Académie Nationale de Pharmacie.

In a hospital environment, the quality control of the hospital preparations allows to release homogeneous batches in a secure way. These controls are totally integrated into the process of production and can also, in certain cases, be realized for high-alert magistral preparations. In community pharmacy, these controls were not required, but the Agence régionale de santé (ARS) recently incited compounding community pharmacies to realize this type of analyses. This decision motivated the creation of a collaboration between the pharmacy department of a French teaching hospital and a society including around thirty community pharmacies having a preparatory. Twenty community pharmacies distributed on all the territory have submitted one of their pediatric preparation, capsules of captopril 2mg, to the pharmacopoeia controls usually realized in the industry or hospital. All the analyzed batches were in agreement with European Pharmacopeia specifications. We shall present the rational of this work, the results as well as the numerous perspectives offered by this new type of collaboration joining completely the logic of a network city-hospital allowing the improvement of security of the medication circuit in France.

Physical activity is a key determinant of public health and contributes to decreasing the prevalence of many diseases. Cancer is the leading cause of death worldwide. Physical activity, accessible to the entire population, could prevent up to 25% of cancers, in addition to improving survival rates and quality of life in cancer patients. Physical activity acts via various mechanisms to slow or decrease tumor growth, including the production and bioavailability of sex hormones, insulin resistance and insulin secretion, and inflammation. In primary prevention, physical activity reduces breast cancer risk by 15-20% and colorectal cancer risk by 24%. All-cause mortality is reduced by 33% in cancer survivors who exercise. Health-related quality of life, fatigue and depression are enhanced by the practice of physical activity in cancer patients. In the general population, the global recommendations on physical activity for health, published by the World Health Organisation, are suggested as a means of primary prevention of cancer. In cancer patients, an adapted physical activity routine is promoted from the very beginning of patient care to decrease fatigue as well as improve tolerance and benefits of treatments.

Worldwide, approximately 5 to 10% of the population is infected by a Human Papilloma Virus (HPV). Some of these viruses, with a high oncogenic risk (HPV HR), are responsible for about 5% of cancer. It is now accepted that almost all carcinomas of the cervix and the vulva are due to an HPV HR (HPV16 and 18) infection. However, these viruses are known to be involved in the carcinogenesis of many other cancers (head and neck [SCCHN], penis, anus). For head and neck cancer, HPV infection is considered as a good prognostic factor. The role of HPV HR in anal cancer is also extensively studied in high-risk patient's population. The role of HPV infection in the carcinogenesis of esophageal, bladder, lung, breast or skin cancers is still debated. Given the multiple possible locations of HPV HR infection, the question of optimizing the management of patients with a HPV+ cancer arises in the implementation of a comprehensive clinical and biological monitoring. It is the same in therapeutics with the existence of a preventive vaccination, for example. Copyright © 2015 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

To develop French recommendations about the management of vaccinations, the screening of cervical cancer and the prevention of pneumocystis pneumonia in systemic lupus erythematosus (SLE). Thirty-seven experts qualified in internal medicine, rheumatology, dermatology, nephrology and pediatrics have selected recommendations from a list of proposition based on available data from the literature. For each recommendation, the level of evidence and the level of agreement among the experts were specified. Inactivated vaccines do not cause significant harm in SLE patients. Experts recommend that lupus patient should receive vaccinations accordingly to the recommendations and the schedules for the general public. Pneumococcal vaccination is recommended for all SLE patients. Influenza vaccination is recommended for immunosuppressed SLE patients. Live attenuated vaccines should be avoided in immunosuppressed patients. Yet, recent works suggest that they can be considered in mildly immunosuppressed patients. Experts have recommended a cervical cytology every year for immunosuppressed patients. No consensus was obtained for the prevention of pneumocystis pneumonia. These recommendations can be expected to improve clinical practice uniformity and, in the longer term, to optimize the management of SLE patients.

Résumé En écologie végétale, le site est un concept central. Un site, c'est l'endroit où une espèce végétale ou une communauté de plantes se développe le site assure un ensemble de conditions dans lesquelles elles vivent. Dans un matériau homogène à l'origine, l'écoulement gravitaire d'une nappe influence les conditions du site par l'intermédiaire de la distribution spatiale des nutriments et d'autres composés chimiques associés. Les remontées d'eau peuvent tout spécialement produire et maintenir les conditions du site essentielles pour différentes espèces et communautés de plantes relativement rares. Les écologues ont porté une attention accrue à ces remontées d'eau, en sorte qu'une coopération avec les hydrologues en a résulté, avec l'émergence d'une discipline propre, l'éco-hydrologie, à la limite des deux domaines scientifiques et liée au concept de site. Aux Pays-Bas, une classification des types d'eau, basée sur l'histoire de l'eau souterraine à proximité de la surface, a été mise en oeuvre pour constituer une base nationale de données géographiques sur les remontées d'eau d'intérêt écologique. Des analyses des correspondances des données de cette base, portant sur l'existence de certaines espèces de plantes, montrent que dans les sols sableux pauvres du Pléistocène la remontée d'eau explique très bien la présence de certaines espèces et communautés, alors que, dans les plaines fluviales et les régions de polders à sols argileux riches, l'influence de la remontée d'eau est masquée par l'importance des caractéristiques des sols. En conclusion donc, certaines espèces de plantes peuvent être utilisées comme des indicateurs de la remontée d'eau dans des diagnostiques et des levés de terrain rapides, mais à condition de prendre en permanence des précautions sur les limites de l'approche.

B components are longer than the orbital period, which we interpret as an evidence of a solar-like differential rotation. Conclusions: Despite their nearly identical fundamental parameters, the components of σ2 CrB system exhibit different magnetic field properties. This indicates that the magnetic dynamo process is a very sensitive function of stellar parameters.

Are body size across the life course and adult height associated with endometriosis? Endometriosis is associated with lean body size during childhood, adolescence and adulthood; tall total adult height; and tall sitting height. The literature suggests that both adult body size and height are associated with endometriosis risk, but few studies have investigated the role of body size across the life course. Additionally, no study has investigated the relationships between components of height and endometriosis. We used a nested case-control design within E3N (Etude Epidémiologique auprès de femmes de l'Education Nationale), a prospective cohort of French women. Data were updated every 2-3 years through self-administered questionnaires. Odds ratios (ORs) and 95% CIs were computed using logistic regression models adjusted for a priori confounding factors. A total of 2416 endometriosis cases were reported as surgically ascertained among the 61 208 included women. The odds of endometriosis were lower among women who reported having a large versus lean body size at 8 years (P for trend = 0.003), at menarche (P for trend < 0.0001) and at ages 20-25 years (P for trend < 0.0001). Women in the highest quartiles of height had statistically significantly increased odds of endometriosis compared to those in the lowest (<158 cm) (162-164 cm: OR = 1.28, 95% CI = 1.12-1.46; ≥165 cm: OR = 1.33, 95% CI = 1.18-1.49, P for trend < 0.0001). Statistically significantly increased odds were also observed among women with a taller sitting height (OR = 1.24, 95% CI = 1.05-1.47, P for trend = 0.01). Leg length was not statistically significantly associated with endometriosis. Endometriosis cases may be prone to misclassification; however, we restricted our case definition to surgically-confirmed cases, which showed a high validation rate. Body size is based on retrospective self-report, which may be subject to recall bias. The results of this study suggest that endometriosis is positively

The National Optical Astronomy Observatory has designed and implemented a prototype educational program designed to test and understand best practices with high school students to promote an understanding of modern astronomy research with its emphasis on large data sets, data tools, and visualization tools. This program, designed to cultivate the interest of talented youth in astronomy, is based on a teen science café model developed at Los Alamos as the Café Scientifique New Mexico. In our program, we provide a free, fun way for teens to explore current research topics in astronomy on Saturday mornings at the NOAO headquarters. The program encourages stimulating conversations with astronomers in an informal and relaxed setting, with free food of course. The café is organized through a leadership team of local high school students and recruits students from all parts of the greater Tucson area. The high school students who attend have the opportunity to interact with expert astronomers working with large astronomical data sets on topics such as killer asteroids, the birth and death of stars, colliding galaxies, the structure of the universe, gravitational waves, gravitational lensing, dark energy, and dark matter. The students also have the opportunity to explore astronomical data sets and data tools using computers provided by the program. The program may serve as a model for educational outreach for the 40+ institutions involved in the LSST.

Year 2006 has been marked in France by the vote in the Parliament of the Planning Act of 28 June, 2006, concerning the sustainable management of radioactive materials and waste. This vote was the achievement of a 15 years research programme performed as required by the previous Research Law of 1991, also known as the Bataille Law, from the name of Christian Bataille, MP, who drafted it and monitored its enforcement as a member of the Parliamentary Office for Scientific and Technological Assessment (Office Parlementaire d'Evaluation des Choix Scientifiques et Techniques - OPECST). At that time a stepwise approach tomore » siting was introduced in the process. It included the study of several alternatives to the geological disposal of long lived high level radioactive waste. Those alternatives have been thoroughly studied and assessed before the Government decided to submit the bill to the Parliament. Experience has been gained not only on the scientific and technical aspects, but also in the field of decision making process, also called now governance. However, not only the results of the research programme were decisive in preparing the bill, but also of major importance were the industrial experience of ANDRA and the rigorous programme management along all those years. Main lessons learnt from the experience are given in this paper. (authors)« less

Probability distribution of financial returns in a model of multiplicative Brownian motion with stochastic diffusion coefficient

Silva, Antonio

2005-03-01

It is well-known that the mathematical theory of Brownian motion was first developed in the Ph. D. thesis of Louis Bachelier for the French stock market before Einstein [1]. In Ref. [2] we studied the so-called Heston model, where the stock-price dynamics is governed by multiplicative Brownian motion with stochastic diffusion coefficient. We solved the corresponding Fokker-Planck equation exactly and found an analytic formula for the time-dependent probability distribution of stock price changes (returns). The formula interpolates between the exponential (tent-shaped) distribution for short time lags and the Gaussian (parabolic) distribution for long time lags. The theoretical formula agrees very well with the actual stock-market data ranging from the Dow-Jones index [2] to individual companies [3], such as Microsoft, Intel, etc. [] [1] Louis Bachelier, ``Th'eorie de la sp'eculation,'' Annales Scientifiques de l''Ecole Normale Sup'erieure, III-17:21-86 (1900).[] [2] A.

La cristallographie est un outil extrêmement puissant qui pourrait être utilisé par de nombreux scientifiques dont les sujets de recherche sont en fait très éloignés. L'évolution des techniques ces dernières années a relégué par exemple la cristallographie des rayons X des petites molécules à un rôle mineur, un rôle de service. Certains ont même le sentiment semble-t-il que toutes les connaissances sont contenues dans de multiples logiciels capables par eux-mêmes de conduire une analyse structurale à un résultat correct unique. Il est souhaitable que chacun soit capable de réaliser l'étude structurale du composé qui l'intéresse et bien entendu nécessaire de comprendre ce que l'on fait, la qualité des résultats et leur analyse en dépend.

The Institut Scientifique Experimental des Transports at Moscow established toward the end of 1925 had since its inception included in its program the study of the mechanism of plastic deformation and the problems associated with it with reference to the materials of the means of transport. Before the program thus determined upon could be carried out, it was necessary to adopt a method of research, or, more exactly, a system of such methods. Because of the modest equipment of the laboratory of the recently established institute, the choice of any particular method was determined not only by the advantages it offered but also by the resources available. As a result of a series of studies and investigations, a method was determined upon which in this paper will be denoted as the micromechanical method. The underlying basis of this method is already known. As will be seen from the description that follows, the micromechanical method is merely a combination of the micrographic study of plastic deformations with mechanical tests on small specimens. It is a well-known fact that a number of investigators have largely employed and still are employing these two procedures and have thereby obtained good results. The authors of the present paper have found it useful to combine the two methods, by making the two studies simultaneously on the sane specimen.

Therapeutic innovation contributes to the increase of health care expenditures in France. Medico-economic evaluation has still a minor role in the decision-making for the registration of drugs and medical devices in hospitals. This study aimed to systematically review published works on medico-economic studies conducted within French hospitals. A literature review was carried out to search for medico-economic studies conducted by hospital teams on therapeutic or diagnostic strategies employed within French hospitals and published from 2010 to 2014. Quality assessment of selected studies was performed according to Drummond et al.'s checklist, which is also used within French guidelines. Of the 44 analyzed articles, methods for identification and measure of costs and results complied with guidelines in 95 % of cases. For results interpretation, compliance was 91 %. Costs discounting (29 %) and the use of sensitivity analysis to account for results uncertainty (70 %) were the parameters with the lowest compliance to guidelines. A good training of health professionals in using economic and statistic tools, and the transferability of results of medico-economic studies are essential and should be optimized to enable a broader use of medico-economic evaluation within the scope of decision-making in French hospitals.

Monogenic auto-inflammatory diseases are characterized by genetic abnormalities coding for proteins involved in innate immunity. They were initially described in mirror with auto-immune diseases because of the absence of circulating autoantibodies. Their main feature is the presence of peripheral blood inflammation in crisis without infection. The best-known auto-inflammatory diseases are mediated by interleukines that consisted in the 4 following diseases familial Mediterranean fever, cryopyrinopathies, TNFRSF1A-related intermittent fever, and mevalonate kinase deficiency. Since 10 years, many other diseases have been discovered, especially thanks to the progress in genetics. In this review, we propose the actual panorama of the main known auto-inflammatory diseases. Some of them are recurrent fevers with crisis and remission; some others evaluate more chronically; some are associated with immunodeficiency. From a physiopathological point of view, we can separate diseases mediated by interleukine-1 and diseases mediated by interferon. Then some polygenic inflammatory diseases will be shortly described: Still disease, Schnitzler syndrome, aseptic abscesses syndrome. The diagnosis of auto-inflammatory disease is largely based on anamnesis, the presence of peripheral inflammation during attacks and genetic analysis, which are more and more performant.

2015-11-01

Hyper-reactive malarial splenomegaly is a rare and severe form of chronic malaria. This condition is a common cause of splenomegaly in endemic areas. The pathophysiology of hyper-reactive malarial splenomegaly involves an intense immune reaction (predominantly B cell-driven) to repeated/chronic infections with Plasmodium sp. The diagnosis may be difficult, due to a poorly specific clinical presentation (splenomegaly, fatigue, cytopenias), a long delay between residence in a malaria-endemic area and onset of symptoms, and a frequent absence of parasites on conventional thin and thick blood smears. A strongly contributive laboratory parameter is the presence of high levels of total immunoglobulin M. When the diagnostic of hyper-reactive malarial splenomegaly is considered, search for anti-Plasmodium antibodies and Plasmodium nucleic acids (genus and species) by PCR is useful. Diagnosis of hyper-reactive malarial splenomegaly relies on the simultaneous presence of epidemiological, clinical, biological and follow-up findings. Regression of both splenomegaly and hypersplenism following antimalarial therapy allows the differential diagnosis with splenic lymphoma, a common complication of hyper-reactive malarial splenomegaly. Although rare in Western countries, hyper-reactive malarial splenomegaly deserves increased medical awareness to reduce the incidence of incorrect diagnosis, to prevent progression to splenic lymphoma and to avoid splenectomy.

[Primary intestinal lymphangiectasia (Waldmann's disease)].

PubMed

Vignes, S; Bellanger, J

2017-08-31

Primary intestinal lymphangiectasia (PIL), Waldmann's disease, is a rare disorder of unknown etiology characterized by dilated intestinal lacteals leading to lymph leakage into the small-bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. PIL is generally diagnosed before 3 years of age but may be diagnosed in older patients. The main symptom is bilateral lower limb edema. Edema may be moderate to severe including pleural effusion, pericarditis or ascites. Protein-losing enteropathy is confirmed by the elevated 24-h stool α1-antitrypsin clearance and diagnosis by endoscopic observation of intestinal lymphangiectasia with the corresponding histology of biopsies. Videocapsule endoscopy may be useful when endoscopic findings are not contributive. Several B-cell lymphomas of the gastrointestinal tract or with extra-intestinal localizations were reported in PIL patients. A long-term strictly low-fat diet associated with medium-chain triglyceride and liposoluble vitamin supplementation is the cornerstone of PIL medical management. Octreotide, a somatostatin analog, have been proposed with an inconsistent efficacy in association with diet. Surgical small-bowel resection is useful in the rare cases with segmental and localized intestinal lymphangiectasia. A prolonged clinical and biological follow-up is recommended.

3D Model of Surfactant Replacement Therapy

Grotberg, James; Tai, Cheng-Feng; Filoche, Marcel

2015-11-01

Surfactant Replacement Therapy (SRT) involves instillation of a liquid-surfactant mixture directly into the lung airway tree. Though successful in neonatal applications, its use in adults had early success followed by failure. We present the first mathematical model of 3D SRT where a liquid plug propagates through the tree from forced inspiration. In two separate modeling steps, the plug first deposits a coating film on the airway wall which subtracts from its volume, a ``coating cost''. Then the plug splits unevenly at the airway bifurcation due to gravity. The steps are repeated until a plug ruptures or reaches the tree endpoint alveoli/acinus. The model generates 3D images of the resulting acinar distribution and calculates two global indexes, efficiency and homogeneity. Simulating published literature, the earlier successful adult SRT studies show comparatively good index values, while the later failed studies do not. Those unsuccessful studies used smaller dose volumes with higher concentration mixtures, apparently assuming a well mixed compartment. The model shows that adult lungs are not well mixed in SRT due to the coating cost and gravity effects. Returning to the higher dose volume protocols could save many thousands of lives annually in the US.

[Cryopyrine-associated periodic syndrome: CAPS seen from adulthood].

PubMed

Koné-Paut, I

2015-04-01

Cryopyrin-associated periodic syndrome is a rare hereditary periodic fever syndrome for which, the genetic mechanism, mutation in the NLRP3 gene, has allowed to gather 3 clinical phenotypes (familial cold urticaria [FCAS], Muckle-Wells syndrome [MWS], and chronic infantile neurological cutaneous and articular syndrome [CINCA]) initially described independently, and to discover the NLRP3 inflammasome, a key receptor of the innate immunity, which regulates the interleukine-1β secretion into the mononuclear cells. The clinical manifestation of CAPS : urticaria-like skin rash, eyes redness, myalgia and sensory deafness are not specific, if considered separately, and that often leads to a wandering diagnosis through a complex medical journey including various specialists. The diagnostic delay is deleterious to patients compromising their quality of life and exposing them to neurosensory complications and renal failure by secondary amyloidosis. The paediatric onset of disease, the family history, the trigger of symptoms by the cold, and the recognition of the skin rash as neutrophilic are important clues before diagnostic confirmation by genetic testing. Interleukine-1 blockade is the only effective treatment of CAPS symptoms which often may stabilize (rarely regression) the sensory involvement and in some cases may allow the regression of secondary amyloidosis.

In West Africa, as in Majority World countries, people with a communication disability are generally cut-off from the normal development process. A long-term involvement of two partners (Orthophonistes du Monde and Handicap International) allowed the implementation in 2003 of the first speech-language pathology qualifying course in West Africa, within the Ecole Nationale des Auxiliaires Medicaux (ENAM, National School for Medical Auxiliaries) in Lome, Togo. It is a 3-year basic training (after the baccalaureate) in the only academic training centre for medical assistants in Togo. This department has a regional purpose and aims at training French-speaking African students. French speech-language pathology lecturers had to adapt their courses to the local realities they discovered in Togo. It was important to introduce and develop knowledge and skills in the students' system of reference. African speech-language pathologists have to face many challenges: creating an African speech and language therapy, introducing language disorders and their possible cure by means other than traditional therapies, and adapting all the evaluation tests and tools for speech-language pathology to each country, each culture, and each language. Creating an African speech-language pathology profession (according to its own standards) with a real influence in West Africa opens great opportunities for schooling and social and occupational integration of people with communication disabilities.

Machine Learning to Improve the Effectiveness of ANRS in Predicting HIV Drug Resistance.

Singh, Yashik

2017-10-01

Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is one of the major burdens of disease in developing countries, and the standard-of-care treatment includes prescribing antiretroviral drugs. However, antiretroviral drug resistance is inevitable due to selective pressure associated with the high mutation rate of HIV. Determining antiretroviral resistance can be done by phenotypic laboratory tests or by computer-based interpretation algorithms. Computer-based algorithms have been shown to have many advantages over laboratory tests. The ANRS (Agence Nationale de Recherches sur le SIDA) is regarded as a gold standard in interpreting HIV drug resistance using mutations in genomes. The aim of this study was to improve the prediction of the ANRS gold standard in predicting HIV drug resistance. A genome sequence and HIV drug resistance measures were obtained from the Stanford HIV database (http://hivdb.stanford.edu/). Feature selection was used to determine the most important mutations associated with resistance prediction. These mutations were added to the ANRS rules, and the difference in the prediction ability was measured. This study uncovered important mutations that were not associated with the original ANRS rules. On average, the ANRS algorithm was improved by 79% ± 6.6%. The positive predictive value improved by 28%, and the negative predicative value improved by 10%. The study shows that there is a significant improvement in the prediction ability of ANRS gold standard.

Though recommended, participation of patients with specific expertise in therapeutic education programs (TEP) is rare. This work reports the experience of a national reference centre for rare systemic diseases. Involvement of "expert patients" (EP) has been planned from the development of a TEP dedicated to systemic lupus: patients' roles and required expertise have been defined and linked to the pedagogical tools. Such patients have been recruited during individual interviews and called to participate to specific pedagogical training. EP intervention have been evaluated by questionnaire to EP and health care providers. Three EP's functions have been identified: sharing experiences, giving "tips and tricks" and promoting dialogue. EP's interventions has been organised into a hierarchy (from sharing to co-animation). Among 298 patients enrolled in the TEP, 25 (8.4%) have been identified as possible EP. Eight of them (32%) benefited from a specific training of 12 hours. Among these patients, two (25%) regularly participate to the education sessions. For EP as well as for health care providers, EP's intervention seems beneficial (visual scale scores of 7.5 and 9.5, respectively). Though difficult to organise, EP's intervention in TEP dedicated to rare systemic diseases seems useful and would earn to be increase.

Anti-leucine rich glioma inactivated 1 encephalitis is a common and a treatable etiology of autoimmune encephalitis. Its diagnosis is a challenge because the initial diagnostic work-up is often normal. A 48-year-old man experienced cognitive and behavioral troubles, facio-brachial dystonic seizures and a syndrome of inappropriate antidiuretic hormone secretion. First line tests excluded infectious, neoplastic, systemic inflammatory, endrocrine or toxic etiologies. Cerebral (18)Fluoro-desoxy-glucose (FDG) position emission tomography and research of specific antibodies in cerebro-spinal fluid and serum led to diagnose an anti-leucine rich glioma inactivated 1 encephalitis. Intravenous immunoglobulins and corticosteroids were partially effective. Cyclophosphamid permitted a good recovery. In the presence of acute neuropsychiatric disorders with a negative etiologic research, physician should think about dysimmune encephalitis. Facio-brachial dystonic seizures and syndrome of inappropriate antidiuretic hormone secretion are highly evocative of anti-leucine rich glioma inactivated 1 encephalitis. The diagnosis needs specific diagnostic tests (cerebral (18)FDG position emission tomography and antibodies research in cerebro-spinal fluid and in serum), after the exclusion of alternative diagnoses. Extensive and repeated diagnostic work-up for neoplasia is required. Immunosupressive therapies are effective in most cases. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

["Placebo effect", from personal convictions to collective representations: A psychosocial reading of a pharmacodynamic phenomenon].

PubMed

Balez, R; Couturaud, F; Touffet, L

2015-11-01

After starting with a brief historical account of the placebo effect organized around the elaboration of clinical trials and around sham therapy as a method, we will offer a psychosocial point of view on the placebo phenomenon. The placebo effect is at the heart of medicine and particularly of therapeutic trials from theoretical research on a drug to its acceptance and its use in every-day clinical practice. The placebo effect intermingles biology, relationships and the context of therapeutic interactions. This type of phenomenon originates as much from biology as from human psychology. Our article puts more precisely into question the part that psychology has in the placebo phenomenon and suggests a chart to address it. This chart refers both to the pharmacodynamic effect given to drugs in a subjective way, and to the collective representations and social interactions depending on them. What can we say about the psychosociological dimensions of the placebo effect? How is it possible to organize the scope of these dimensions to base systematic studies on them in the field of clinical trials? We try to give elements of response to these questions by suggesting the study of the placebo effect as an original field of study by necessarily mobilizing both health sciences and the human and social sciences.

[Electronic cigarettes: A therapeutic tool, a social phenomenon or a business?].

PubMed

Berlin, I

Smoking is the first avoidable cause of morbidity and mortality. It is estimated that there were around 14 million smokers in France in 2012 and that smoking results in 70,000 deaths per year. All types of interventions reducing with efficacy the incidence and prevalence of smoking are to consider in prolonging life expectancy. Electronic cigarettes (e.cig.) are a social phenomenon but they also are a system delivering pharmacologically active substances; their use concerns today several millions of individuals in France. By this fact, it became important for clinical practitioners to acquire some knowledge about e. cig. Most of the e.cig. contains nicotine, thus, e.cig. are now called in the medical literature as electronic nicotine delivery system (ENDS). It is highly plausible that ENDS, which are, as of today, consumer products and not health products, deliver nicotine with a good bioavailability and could, if largely used, help to reduce smoking prevalence. However, because of current lack of regulations, as of today, the risk/benefit ratio of ENDS as an aid to help smokers quit and their adverse effect profile cannot be established. It is of public health responsibility to promote evidence based knowledge about e.cig. to know with confidence their risk/benefit ratio.

Nutrient profiling ranks foods based on their nutrient content. They may help identify foods with a good nutritional quality for their price. This hypothesis was tested using diet modeling with linear programming. Analyses were undertaken using food intake data from the nationally representative French INCA (enquête Individuelle et Nationale sur les Consommations Alimentaires) survey and its associated food composition and price database. For each food, a nutrient profile score was defined as the ratio between the previously published nutrient density score (NDS) and the limited nutrient score (LIM); a nutritional quality for price indicator was developed and calculated from the relationship between its NDS:LIM and energy cost (in euro/100 kcal). We developed linear programming models to design diets that fulfilled increasing levels of nutritional constraints at a minimal cost. The median NDS:LIM values of foods selected in modeled diets increased as the levels of nutritional constraints increased (P = 0.005). In addition, the proportion of foods with a good nutritional quality for price indicator was higher (P < 0.0001) among foods selected (81%) than among foods not selected (39%) in modeled diets. This agreement between the linear programming and the nutrient profiling approaches indicates that nutrient profiling can help identify foods of good nutritional quality for their price. Linear programming is a useful tool for testing nutrient profiling systems and validating the concept of nutrient profiling.

Representation-based user interfaces for the audiovisual library of the year 2000

The audiovisual library of the future will be based on computerized access to digitized documents. In this communication, we address the user interface issues which will arise from this new situation. One cannot simply transfer a user interface designed for the piece by piece production of some audiovisual presentation and make it a tool for accessing full-length movies in an electronic library. One cannot take a digital sound editing tool and propose it as a means to listen to a musical recording. In our opinion, when computers are used as mediations to existing contents, document representation-based user interfaces are needed. With such user interfaces, a structured visual representation of the document contents is presented to the user, who can then manipulate it to control perception and analysis of these contents. In order to build such manipulable visual representations of audiovisual documents, one needs to automatically extract structural information from the documents contents. In this communication, we describe possible visual interfaces for various temporal media, and we propose methods for the economically feasible large scale processing of documents. The work presented is sponsored by the Bibliotheque Nationale de France: it is part of the program aiming at developing for image and sound documents an experimental counterpart to the digitized text reading workstation of this library.

Benefits of pharmacist-led flu vaccination services in community pharmacy.

Kirkdale, C L; Nebout, G; Megerlin, F; Thornley, T

2017-01-01

Seasonal influenza is a major cause of excess winter deaths and increased hospital admissions. There is a high level of economic burden associated with the infection. Although vaccination targets have been set to tackle this international issue, many countries struggle to reach these coverage targets for their at-risk populations using traditional delivery methods. Traditional providers include family doctors and nurses; however, pharmacist-led influenza vaccination has become a more commonly utilised aid to support vaccination targets. Community pharmacies are convenient and widely accessible and evaluations consistently demonstrate that patients are satisfied with pharmacist-led vaccinations. Allowing community pharmacists to administer influenza vaccination as an alternative option for delivery helps to increase the coverage rate of vaccination. In addition, commissioning community pharmacists to provide this service has been shown to contribute to achieving targets for those at-risk. Pharmacist-led influenza vaccination services can create value for payors and reduce pressure on health systems. This review aims to demonstrate the success of pharmacy-led influenza vaccinations, and the impact it has had in driving up immunisation rates within other countries. Experiences of countries such as England, Portugal and the United States provide evidence to demonstrate the benefit to both the patient and the health system.

Tetanus is a serious disease, which could be potentially lethal. All cases are observed in patients inadequately immunized. The immunochromatographic tests (including Tetanos quick Stick(®) [TQS]) have demonstrated their efficiency in emergency setting. The aim of our study was to assess the usefulness of these tests in elderly outpatients seen in ambulatory settings. This prospective study included patients aged 65 years and over who presented to the outpatients' clinic of the Gerontologic Departmental Center (Marseille). A TQS and a self-administered questionnaire to assess risk factors for tetanus were performed. One hundred and twenty-two patients were studied. The prevalence of positive TQS was 66%. Patients have an average of 2.5 risk factors for tetanus. Negative TQS was observed in 35% of patients who had seen their general practitioner for a wound during the previous year. Elderly patients accumulate several risk factors regardless of age and lifestyle. While physicians are familiar with the vaccine recommendations, they are often faced with the difficulty of assessing patient's status based only on the patient's interview, which is frequently not reliable. The implementation of immunochromatographic tests in general practice could help physicians in the management of patients at risk for tetanus.

Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament), the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP) breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof) of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France). The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse) were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%), infection (22.2%), and capsular contracture (13.6%). Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel.

2016-01-01

Accidental direct intravenous injection of a concentrated solution of potassium often leads to patient death. In France, recommendations of healthcare agencies to prevent such accidents cover only preparation and intravenous infusion conditions. Accidents continue to occur in French hospitals. These facts demonstrate that these recommendations are insufficient and ineffective to prevent such deaths, especially those occurring during a catheter flushing. This article reviews the measures able to reduce the number of accidents. Countries which removed concentrated ampoules from ward stocks observed a decrease of the number of accidental deaths. This withdrawal, recommended by the World Health Organization, is now part of standards in studies aimed at determining the safety of care in hospitals. However, removal alone is insufficient to eliminate the risk. The combination with other measures should be considered. These measures are the provision of a combination of diluted intravenous ready to use solutions, the promotion of the oral route with tablets and oral solutions for potassium replenishment and to make available products with safeguards to prevent single shot intravenous injection. Studies aimed at determining the consequences on preventing concentrated potassium accidents of a widespread distribution of isotonic sodium chloride pre-filled ready-to-use syringes for catheter flushing should be performed.

Pottier, P; Planchon, B

2011-06-01

Clinical reasoning is a highly complex system with multiple inter-dependent mental activities. Gaining a better understanding of those cognitive processes has two practical implications: for physicians, being able to analyse their own reasoning method may prove to be helpful in diagnostic dead end; for medical teachers, identifying problem-solving strategies used by medical students may foster an appropriate individual feed-back aiming at improving their clinical reasoning skills. On the basis of a detailed literature review, the main diagnostic strategies and their related pattern of mental processes are described and illustrated with a concrete example, going from the patient's complaint to the chosen solution. Inductive, abductive and deductive diagnostic approaches are detailed. Different strategies for collecting data (exhaustive or oriented) and for problem-building are described. The place of problem solving strategies such as pattern-recognition, scheme inductive process, using of clinical script, syndrome grouping and mental hypotheses test is considered. This work aims at breaking up mental activities in process within clinical reasoning reminding that expert reasoning is characterised by the ability to use and structure the whole of these activities in a coherent system, using combined strategies in order to guarantee a better accuracy of their diagnosis.

This work aims to provide staff accreditation methodology to harmonize and secure practices for parenteral nutrition bags preparation. The methodology used in the present study is inspired from project management and quality approach. Existing training supports were used to produce accreditation procedure and evaluation supports. We first defined abilities levels, from level 1, corresponding to accredited learning agent to level 3, corresponding to expert accredited agent. Elements assessed for accreditation are: clothing assessment either by practices audit or by microbiologic test, test bags preparation and handling assessment, bag production to assess aseptic filling for both manual or automatized method, practices audit, number of days of production, and non-conformity following. At Angers Hospital, in 2014, production staff is composed of 12 agents. Staff accreditation reveals that 2 agents achieve level 3, 8 agents achieve level 2 and 2 agents are level 1. We noted that non-conformity decreased as accreditation took place from 81 in 2009 to 0 in 2014. To date, there is no incident due to parenteral bag produced by Angers hospital for neonatal resuscitation children. Such a consistent study is essential to insure a secured nutrition parenteral production. This also provides a satisfying quality care for patients. Copyright © 2016 Académie Nationale de Pharmacie.

Redistribution of annexin in gravistimulated pea plumules

We used immunocytochemistry to investigate the effects of gravistimulation on annexin localization in etiolated pea plumule shoots. In longitudinal sections, an asymmetric annexin immunostaining pattern was observed in a defined group of cells located just basipetal to apical meristems at the main shoot apex and at all of the axillary buds, an area classically referred to as the leaf gap. The pattern was observed using both protein-A-purified anti-annexin and affinity-purified anti-annexin antibodies for the immunostaining. A subset of the cells with the annexin staining also showed an unusually high level of periodic acid Schiff (PAS) staining in their cell walls. Prior to gravistimulation, the highest concentration of annexin was oriented toward the direction of gravity along the apical end of these immunostained cells. In contrast, both at 15 and 30 min after gravistimulation, the annexin immunostain became more evenly distributed all around the cell and more distinctly cell peripheral. The asymmetry along the lower wall of these cells was no longer evident. In accord with current models of annexin action, we interpret the results to indicate that annexin-mediated secretion in the leaf gap area is preferentially toward the apical meristem prior to gravistimulation, and that gravistimulation results in a redirection of this secretion. These data are to our knowledge the first to show a correlation between the vector of gravity and the distribution of annexins in the cells of flowering plants. c 2000 Editions scientifiques et medicales Elsevier SAS.

An international conference on Transposable Elements (TEs) was held 21-24 April 2012 in Saint Malo, France. Organized by the French Transposition Community (GDR Elements Génétiques Mobiles et Génomes, CNRS) and the French Society of Genetics (SFG), the conference's goal was to bring together researchers from around the world who study transposition in diverse organisms using multiple experimental approaches. The meeting drew more than 217 attendees and most contributed through poster presentations (117), invited talks and short talks selected from poster abstracts (48 in total). The talks were organized into four scientific sessions, focused on: impact of TEs on genomes, control of transposition, evolution of TEs and mechanisms of transposition. Here, we present highlights from the talks given during the platform sessions. The conference was sponsored by Alliance pour les sciences de la vie et de la santé (Aviesan), Centre national de la recherche scientifique (CNRS), Institut national de la santé et de la recherche médicale (INSERM), Institut de recherche pour le développement (IRD), Institut national de la recherche agronomique (INRA), Université de Perpignan, Université de Rennes 1, Région Bretagne and Mobile DNA.

2015-10-01

Ce livre revisite l'histoire de l'art dans ce qu'elle a de plus universel : son rapport au ciel. De l'Orient à l'Occident, de l'Antiquité à l'époque contemporaine, du classique au plus inattendu, il crée un espace singulier où se mêlent art et science, un musée imaginaire croisant sensibilité intime et compréhension du Cosmos, un jeu sans cesse réinventé...; car il n'y a pas une seule manière de regarder les étoiles. Bien sûr, le ciel possède un énorme pouvoir évocateur, une force inspiratrice à nulle autre pareille, mais l'inspiration n'est pas la seule des relations entre l'art et l'astronomie. En effet, les artistes peuvent apporter leur grain de sel aux révolutions scientifiques, tandis que l'astronomie peut aider à comprendre certaines œuvres. Avec près de 600 illustrations, cet ouvrage n'a pas pour but d'égrener la liste exhaustive des représentations de ciel étoilé, clair de lune, ambiance crépusculaire ou soleil de midi, mais plutôt d'aborder les multiples relations entre l'art et la science. Il s'agit d'une invitation à un voyage aux frontières mouvantes et incertaines des plus belles réalisations de l'esprit humain.

Le Systeme Hybride Eolien-Diesel avec Stockage d'Air Comprime (SHEDAC) utilise l'hybridation pneumatique pour remplacer la consommation des combustibles fossiles par de l'energie renouvelable, plus particulierement de l'energie eolienne. Le surplus de l'energie eolienne est utilise pour comprimer et stocker de l'air qui est utilise ensuite pour suralimenter le moteur diesel. Le memoire de maitrise est constitue de deux articles scientifiques. Le premier article presente le developpement d'un logiciel dedie a l'etude de faisabilite d'un systeme eolien-diesel avec stockage d'air comprime. Cette etude est basee sur l'analyse des couts et des revenus, des couts des equipements (eolienne, moteur diesel, systeme de stockage d'air). Elle est completee par une analyse de sensibilite aux differents parametres, une analyse des risques et des emissions des gaz a effet de serre (GES). Le deuxieme article est une application de ce logiciel pour l'installation d'un systeme SHEDAC au camp minier Esker au Quebec en remplacement des sources actuelles de production d'energie. L'utilisation du stockage d'air comprime a l'aide d'un systeme SHEDAC est le plus rentable par rapport a l'utilisation de l'energie eolienne seule ou d'une centrale thermique au diesel seule ou des deux combinees. Avec une valeur actuelle nette et un taux de rendement interne plus eleves, cette solution permet d'obtenir le plus bas cout de l'energie pour cette region eloignee. None None None

Calculations of dose distributions using a neural network model.

The main goal of external beam radiotherapy is the treatment of tumours, while sparing, as much as possible, surrounding healthy tissues. In order to master and optimize the dose distribution within the patient, dosimetric planning has to be carried out. Thus, for determining the most accurate dose distribution during treatment planning, a compromise must be found between the precision and the speed of calculation. Current techniques, using analytic methods, models and databases, are rapid but lack precision. Enhanced precision can be achieved by using calculation codes based, for example, on Monte Carlo methods. However, in spite of all efforts to optimize speed (methods and computer improvements), Monte Carlo based methods remain painfully slow. A newer way to handle all of these problems is to use a new approach in dosimetric calculation by employing neural networks. Neural networks (Wu and Zhu 2000 Phys. Med. Biol. 45 913-22) provide the advantages of those various approaches while avoiding their main inconveniences, i.e., time-consumption calculations. This permits us to obtain quick and accurate results during clinical treatment planning. Currently, results obtained for a single depth-dose calculation using a Monte Carlo based code (such as BEAM (Rogers et al 2003 NRCC Report PIRS-0509(A) rev G)) require hours of computing. By contrast, the practical use of neural networks (Mathieu et al 2003 Proceedings Journees Scientifiques Francophones, SFRP) provides almost instant results and quite low errors (less than 2%) for a two-dimensional dosimetric map.

Simulation-based learning (SBL) is developing rapidly in France and the question of its use in the teaching of internal medicine (IM) is essential. While HAS encourages its integration into medical education, French Young Internists (AJI) set up a working group to reflect on the added-value of this tool in our specialty. Different sorts of SBL exist: human, synthetic and electronic. It enables student to acquire and evaluate technical skills (strengths, invasive procedures, etc.) and non-technical skills (relational, reasoning…). The debriefing that follows the simulation session is an essential time in pedagogical terms. It enables the acquisition of knowledge by encouraging the students' reflection to reshape their reasoning patterns by self-correcting. IM interns are supportive of its use. The simulation would allow young internists to acquire skills specific to our specialty such as certain gestures, complex consulting management, the synthesis of difficult clinical cases. SBL remains confronted with human and financial cost issues. The budgets allocated to the development and maintenance of simulation centres are uneven, making the supply of training unequal on the territory. Simulation sessions are time-consuming and require teacher training. Are faculties ready to train and invest their time in simulation, even though the studies do not allow us to conclude on its pedagogical validity?

Microwave freeze-thaw treatment (MFTT) of injectable drugs can support the development of centralized intravenous admixtures services (CIVAS). The aim of the review is to collect information and results about this method. A systematic review of the scientific literature about injectable drug stability studies was performed. The data are presented in a table and describe name of the drug, producer, final concentration, temperature and time of freezing storage, type of microwave oven, thawing power, method of dosage and results after treatment or final long-term storage at 5±3 °C. From 1980 to 2014, 59 drugs were studied by MFTT and the results were presented in 49 publications. Forty papers were presented by 8 teams (2 to 18 by team). The temperatures of freezing storage vary from -70 °C to -10 °C, the time storage from 4 hours to 12 months, the thaw from low to full power. Dosages are mainly made by high performance liquid chromatography. Most of the 59 drugs are stable during and after treatment. Only 3 teams have tested the long-term stability after MFTT, the first for ganciclovir after 7 days, the second for ceftizoxime after 30 days and the third for 19 drugs after 11 to 70 days. This review can help CIVAS to take in charge the productions of ready-to-use injectable drugs. Copyright © 2015 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS.

To compare the food consumption and nutrient intakes of German children and adolescents in the 1980s with present dietary habits. Two cross-sectional representative surveys, the German National Food Consumption Study (Nationale Verzehrsstudie, NVS) from 1985-8 and the nutrition module 'EsKiMo' of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) from 2006, were analysed for differences in food and nutrient intakes stratified by age and sex groups. Secondary analyses of data from representative observational studies. Children and adolescents aged 6-17 years living in Germany in the 1980s (n 2265) and in 2006 (n 2506). Food consumption was characterised by higher amounts of vegetables/pulses, fruits/nuts and beverages and less meat products/sausages, butter, fats/oils, potatoes/potato products and bread/pastries in 2006 than in 1985-8. The overall changes in food intake were reflected in improvements of macronutrient composition, increased water intake and lower energy density of the diet. Intake of most vitamins and minerals increased in relation to energy intake, but the nutrient density of the diet for vitamins B12 and D decreased. The most critical nutrients observed in NVS and EsKiMo were folate, vitamin D, vitamin A, vitamin E, Ca and Fe. In addition, dietary fibre intake was relatively low and fatty acid and carbohydrate compositions were not favourable. Further efforts will be necessary to improve dietary habits among children and adolescents.

Case management is a new professional field in France. It is addressed to elderly persons living in community whose situation is regarded as particularly complex. Case managers have to assess needs and coordinate necessary services. One common criteria of complexity is refusal of care. The objective of this study is to compare the words of users with those of case managers about refusal of care, in order to understand its meaning, professionals' attitudes and ethical challenges. Two researchers have cooperated on this qualitative research: the first one, anthropologist, interviewed 19 individuals, and 11 of their caregivers. The second one, geriatrician and researcher in medical ethics, lead four focus groups gathering a total of 18 case managers. Refusal of care often is the result of the will of preserving one's identity, compromised by illness. Individuals seek control on their life. Facing this behaviour, case managers try to secure the individual, by establishing a personal relationship that respects their choices, even if care has to be delayed. Refusal of care may sometimes disclose a desire to vanish, in front of which professionals meet their own limits. To recognise an elderly person that refuses care as a unique individual who can make choices secure his identity, and allow him to change.

Some studies suggest that thrombotic thrombocytopenic purpura (TTP) occurs more often in African Americans. However there is low evidence for this in the literature. The aim of our study was to describe the clinical and biological characteristics of TTP in the Afro-Caribbean population of Martinique. We retrospectively analysed all patients with TTP diagnosed at the Fort-de-France hospital between 2008, January 1st and 2015, December 31st. Diagnosis was confirmed if ADAMTS-13 activity was<10 %. Ten patients were included, corresponding to an average annual incidence of 3.2 cases/year/million individuals. None of the patient presented with the association of the five characteristic features of TTP. Microangiopathic haemolytic anaemia and severe peripheral thrombocytopenia (median: 13G/L) was the main presentation leading to diagnosis. There was no kidney involvement in 90 % of all patients, but severe neurological manifestations occurred in 70 %. Classical management including corticosteroids and plasma exchanges allowed clinical remission in 6 out of the 10 cases. If necessary, rituximab or cyclophosphamide was used. The overall survival rate was 90 %. In Martinique, the incidence of TTP is twice that reported in similar studies in France. Clinical manifestations seem to differ by more common and more severe neurological involvement. Mortality is low, in part, due to optimal care.

To evaluate the economic impact of future prescriptions of etanercept and adalimumab biosimilars at the territorial scale covered by PharmAlp'Ain, a hospitals grouping of orders for health products. Determination of the number and status of patients (naive or in continuation of treatment) from the National Database "Datamart de Consommation Inter-Régimes" of health insurance, concerned by a dispensation in a pharmacy of etanercept or adalimumab in 2015. Calculation of potential savings in case of biosimilar requirements according to 3 hypotheses: 63% (rate observed in a previous study) of initiations are treated with biosimiliaries and the others by princeps (H 1 ); all initiations under biosimilars and continuation therapy with the princeps (H 2 ) or all patients are treated with biosimilars (H 3 ). The annual savings are estimated at 237,000 € with the H 1 hypothesis. In the case of H 2 , the expected savings would be 376,200 € per year. In the case of H 3 , savings for the community could reach almost 1,282,800 € per year. The arrival of biosimilars allows significant savings for medicines market. According to the French recommendations in 2016, the expected savings are between the H 1 and H 2 hypothesis. The rate of penetration of biosimilars depends on many factors such as the involvement of health professionals, patient adherence, or health authority recommendations.

The development of information systems in French hospitals is mandatory. The aim of this work was to analyze the content of exchanges carried out within social networks, dealing with problems encountered with hospital pharmacies information systems. Messages exchanged via the mailing list of the Association pour le Digital et l'Information en Pharmacie and abstracts of communications presented at hospital pharmacists trade union congresses were analyzed. Those referring to information systems used in hospital pharmacies were selected. From March 2015 to June 2016, 122 e-mails sent by 80 pharmacists concerned information systems. From 2002 to 2016, 45 abstracts dealt with this topic. Problems most often addressed in these 167 documents were "parameterization and/or functionalities" (n=116), interfaces and complexity of the hospital information systems (n=52), relationship with health information technologies vendors and poor reactivity (n=32), additional workload (n=32), ergonomics (n=30), insufficient user training (n=22). These problems are interdependent, lead to errors and in order to mitigate their consequences, they compel pharmacy professionals to divert a significant amount of working hours to the detriment of pharmaceutical care and dispensing and preparing drugs. Hospital pharmacists are faced with many problems of insecurity and inefficiency generated by information systems. Researches are warranted to determine their cost, specify their deleterious effects on care and identify the safest information systems. Copyright © 2018 Académie Nationale de Pharmacie.

Plague is a bacterial zoonosis caused by Yersinia pestis, usually found in fleas and small rodents that constitute the reservoir of the disease. It is transmitted to humans by flea bite, contact with rodents or inhalation of infected droplets. There are three clinical forms: bubonic plague, pulmonary plague and septicemic plague. The usual presentation is a flu-like syndrome possibly accompanied by an inflammatory lymphadenopathy which appears after 1 to 7days of incubation. Bubonic plague has a case fatality rate of about 50% while other forms of plague are almost always fatal without treatment. Diagnosis can be confirmed by usual bacteriological techniques (Gram examination, culture) but also by serological examination, use of rapid diagnostic tests or PCR. Although aminoglycosides are traditionally regarded as the most effective treatment, fluoroquinolones or cyclins are currently recommended in France. Plague is one of the re-emerging diseases according to the WHO and Madagascar suffered in 2017 the most important plague epidemic of the 21st century with more than 2000 cases and 200 deaths. Peru and the Democratic Republic of Congo are also considered endemic areas. Public health measures and a relentless fight against poverty are the cornerstone of the control of the disease. Vaccine improvement in endemic areas may also play an important role. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

[Gut microbiota: Description, role and pathophysiologic implications].

Landman, C; Quévrain, E

2016-06-01

The human gut contains 10(14) bacteria and many other micro-organisms such as Archaea, viruses and fungi. Studying the gut microbiota showed how this entity participates to gut physiology and beyond this to human health, as a real "hidden organ". In this review, we aimed to bring information about gut microbiota, its structure, its roles and its implication in human pathology. After bacterial colonization in infant, intestinal microbial composition is unique for each individual although more than 95% can be assigned to four major phyla. The use of culture independent methods and more recently the development of high throughput sequencing allowed to depict precisely gut microbiota structure and diversity as well as its alteration in diseases. Gut microbiota is implicated in the maturation of the host immune system and in many fundamental metabolic pathways including sugars and proteins fermentation and metabolism of bile acids and xenobiotics. Imbalance of gut microbial populations or dysbiosis has important functional consequences and is implicated in many digestive diseases (inflammatory bowel diseases, colorectal cancer, etc.) but also in obesity and autism. These observations have led to a surge of studies exploring therapeutics which aims to restore gut microbiota equilibrium such as probiotics or fecal microbiota transplantation. But recent research also investigates biological activity of microbial products which could lead to interesting therapeutics leads.

Pre-eclampsia prevention represents a major public health issue, as this vasculo-placental disorder generates a great burden of foeto-maternal morbi-mortality. Aspirin has proved its efficacy in primary and secondary pre-eclampsia prevention, especially when it is given at 150mg per day bedtime before 15 weeks of gestation to high-risk women. In the English trial ASPRE, high-risk women were identified by an algorithm taking into account angiogenic biomarkers ascertained at the end of first trimester of pregnancy. This article focuses on physiopathological mechanisms and risk factors of pre-eclampsia and on the interest of early angiogenic biomarkers dosing during pregnancy, for the assessment of pre-eclampsia risk. Unlike Great Britain or Israel, cost-effectiveness of this algorithm in general population has not been assessed in France. Finally, systemic lupus erythematous is at high risk of vasculo-placental disorders. Although few studies of angiogenic biomarkers dosing during lupus pregnancies identified a correlation between high sFlt1 levels at the end of first trimester and subsequent onset of severe vasculo-placental disorders, with a very good negative predictive value of sFtl1. Angiogenic biomarkers ascertainment for screening of vasculo-placental disorders in pregnant women with systemic lupus erythematous could allow targeting at best women needing an aspirin treatment and a closer monitoring.

The objective of the present study was to determine the potential long-term impact of dietary habits on age-related decline among 4809 elderly women (born between 1925 and 1930) in the 'Etude Epidémiologique de Femmes de la Mutuelle Générale de l'Education Nationale' (E3N) study, a French epidemiological cohort. In 1993, an extensive diet history self-administered questionnaire was sent to all participants, and in 2006 another questionnaire on instrumental activities of daily living (IADL) and recent cognitive change was sent to a close relative or friend of each woman. Logistic models adjusted for socio-demographic, lifestyle and health factors were performed to evaluate associations between habitual dietary intakes and two outcomes of interest based on the informant response: recent cognitive decline and IADL impairment. Recent cognitive decline was associated with lower intakes of poultry, fish, and animal fats, as well as higher intakes of dairy desserts and ice-cream. IADL impairment was associated with a lower intake of vegetables. The odds of recent cognitive decline increased significantly with decreasing intake of soluble dietary fibre and n-3 fatty acids but with increasing intake of retinol. The odds of IADL impairment increased significantly with decreasing intakes of vitamins B2, B6 and B12. These results are consistent with a possible long-term neuroprotective effect of dietary fibre, n-3 polyunsaturated fats and B-group vitamins, and support dietary intervention to prevent cognitive decline.

Administration of parenteral iron is a mainstay of iron deficiency treatment. Evaluation and control of this element is an issue for healthcare facilities. Study of parenteral iron use is thus to be evaluated in its impact in terms of hospital economics. Parenteral iron administrations that took place on 2014 in our healthcare facility were retrospectively identified by pharmacists. Following data were extracted from Pharma™ and Crossway™ softwares: indication, diagnostic coding and total dose of iron received. They were then compared to the summary of product characteristics. Of 198 analyzed prescriptions, iron deficiency was known or suspected for 97% of patients. However, the total dose of iron administered was not in compliance for three quarters of prescriptions. Sixty-eight percent of patients appear under-dosed. Administration's traceability was found for two-thirds. Eighty-five hospital discharges did not have the right coding and 34 stays were charged like an external act instead sessions. Financial loss for the hospital is estimated at 49,300 euros. As part of improving practice, close pharmaceutical monitoring of parenteral iron prescribed dosing regimen is essential. Effective communication with the medical information department and regular awareness raising of prescribers should also allow to give more value to this act. Hospital economics is a real tool to aid decision-making. Copyright © 2015 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS. All rights reserved.

Olfaction is a complex sensory system, and increasing interest is being shown in the link between olfaction and cognition, notably in the elderly. In this literature review, we revisit the specific neurophysiological features of the olfactory system and odorants that lead to a durable olfactory memory and an emotional memory, for which the implicit component produces subconscious olfactory conditioning. Olfaction is known to affect cognitive abilities and mood. We also consider the impairment of olfactory function due to ageing and to neurodegenerative diseases, in particular Alzheimer's disease and Parkinson's disease, through anatomopathological changes in the peripheral and central olfactory structures. The high frequency of these olfactory disorders as well as their early occurrence in Alzheimer disease and Parkinson disease are in favour of their clinical detection in subjects suffering from these two neurodegenerative diseases. Finally, we analyse the impact of olfactory stimulation on cognitive performance and attention. Current observational data from studies in elderly patients with Alzheimer-type dementia are limited to multiple sensory stimulation methods, such as the Snoezelen method, and aromatherapy. These therapies have shown benefits for dementia-related mood and behaviour disorders in the short term, with few side effects. Since olfactory chemosensory stimulation may be beneficial, it may be proposed in patients with dementia, especially Alzheimer-type dementia, as a complementary or even alternative therapy to existing medical strategies.

Long-term industrial management of radioactive waste in France is carried out by the Agence Nationale pour la gestion des Dechets Radioactifs. (ANDRA), which is a public body responsible mainly for siting, design, construction, and operation of the disposal facilities for every kind of radioactive waste produced in the country. Furthermore, ANDRA has to define and control the required quality of waste packages delivered for disposal. As far as disposal is concerned, it is customary in France to classify waste in two main categories. The first category includes all the so-called short-lived low-level waste (LLW) containing mainly radioactive substances have

The recommended daily dose of acetaminophen is limited to 60mg/kg/day with a maximum of 3g daily dose in adults weighing less than 50kg or in patients undergoing certain risk factors. This study aimed at assessing the fulfillment of those recommendations and the possible impact on the liver dysfunction at supra-therapeutic doses of acetaminophen. This study was performed one day in 9 services. Patients characteristics, acetaminophen dose, daily dose administered, physiopathological aspects, markers of liver damage were collected. Among 542 prescriptions analyzed, 343 of them contained acetaminophen. The median age of patients studied was 81 years and one third weighed less than 50kg. The main risk factor of supra-therapeutic prescriptions was the lack of dose acetaminophen based on weight with 14% patients concerned and this risk raised at 17% when the pathophysiological conditions were included. The presence of pharmacists in medicals departments was more effective than the use of informatics programs limiting the dose systematically to 3g/day, or a distant pharmaceutical validation from care services to reduce the risk of acetaminophen overdose. According to the statement of administrations, only 4 of 49 patients received doses above 60mg/kg/day with a low impact on liver function tests. The continuous presence in pharmaceutical care services was the most effective measure to ensure effective implementation of acetaminophen recommendations.

Type 2 diabetes is a major public health concern because of its prevalence, the severity of complications and the financial implications. Compliance and patient's autonomy in medications intake play key roles in the success of treatment. Pharmacists' interviews ensure an optimized and individual follow-up. Type 2 diabetes is not one of the targeted diseases to perform pharmacists' interviews on under Health Insurance. We thus judged useful to contribute to their development. We applied a cross-disciplinary methodological process in order to define the specifications of the follow-up form useful to conduct the pharmacist's interview 1 by focusing on the identification of a non-compliance and its origins. A feasibility study was carried out in order to check its workability to the pharmacy practice. The follow-up form, associated with a pharmacist practical guide, includes 3 parts: (1) General informations, (2) Survey establishing patient's knowledge, (3) Summary including a level of knowledge assessment grid. Outcomes provide a long but appropriate-felt duration, few difficulties to conduct the interview and a proven usefulness in 90% of all cases that make the follow-up form suitable to the pharmacy practice. This tool could serve as a model for the pharmacist to conduct his future interviews for the type 2 diabetes patients, thus improving patient care, together with other health professionals.

Mucociliary clearance is the transport at the surface of airways of a complex fluid layer, the mucus, moved by the beats of microscopic cilia present on epithelial ciliated cells. We explored the coupling between the spatial organisation and the activity of cilia and the transport of surface fluids on reconstituted cultures of human bronchial epithelium at air-liquid interface, obtained by human biopsies. We reveal the existence of stable local circular surface flow patterns of mucus or Newtonian fluid at the epithelium surface. We find a power law over more than 3 orders of magnitude showing that the average ciliated cell density controls the size of these flow patterns, and, therefore the distance over which mucus can be transported. We show that these circular flow patterns result from the radial linear increase of the local propelling forces (due to ciliary beats) on each flow domain. This linear increase of local forces is induced by a fine self-regulation of both cilia density and orientation of ciliary beats. Local flow domains grow and merge during ciliogenesis to provide macroscopic mucus transport. This is possible only when the viscoelastic mucus continuously exerts a shear stress on beating cilia, revealing a mechanosensitive function of cilia. M. K.

2018-06-03

To determine whether career development in academic medicine is more difficult for women than for men, and, if any, the nature and level of barriers to this progression. Extraction of full-time medical staff in a Parisian hospital group, through the SIGAPS platform; an online questionnaire survey of career choices and barriers experienced by full-time male and female physicians. The study population comprises 181 hospital practitioners and 141 academic physicians (49 associate professors and 92 full professors). Women represent 49% of the medical staff but 15% of full professors. This underrepresentation of women is more important among intensivists/anesthesiologists than technique-based specialists (such as radiologists, biologists…). There is no difference in scientific output, marital status and parenthood between women and men. On the other hand, there is a difference in attitudes highlighted by the EVAR risk-taking scale as well as in the burden of familial involvement and the prejudices felt by women during the academic selection process. The glass ceiling exists in one of the largest French hospital group. Career development principles promote merit, but should decrease the benefit of "masculine" attitudes in the competition for academic positions. Academic selection criteria should evolve to limit the disadvantage of women related to deeper familial involvement and less competitive strategies and risk-taking attitudes.

HIV infection affects about 150,000 people in France. In total, 30,000 of them are unaware of their serostatus. In this context, HIV self-testing has arrived in France in September 2015. The aim of our study was to analyze the level of application of the recommendations during the purchase of an HIV self-test. Our primary hypothesis was that the delivered information is poor. We realized a comprehensive transversal and observational study with surveys without modification of practice in all Caen pharmacies. The primary endpoint was the seller's assessment of the presence or possibility of an emergency situation requiring a post-exposure prophylaxis and suitability assessment of self-testing for the patient's case. Seven pharmacies out of the 41 visited (17.07%) validated our primary endpoint. In all pharmacies, 43.9% had HIV self-tests available for sale. The availabality of the self-tests is linked to the main endpoint (P<0.005). In total, 31.71% of the vendors redirected the patient to another method of screening (general practitioner, sexual health clinic…). The delivered information about HIV self-tests is poor. Improving it would put the pharmacist at the heart of the HIV screening strategy. The introduction of training for the professionnals in our region could be interesting to improve the dispensing of the self-tests. Copyright © 2018 Académie Nationale de Pharmacie.

Forensic entomology: implementing quality assurance for expertise work.

PubMed

Gaudry, Emmanuel; Dourel, Laurent

2013-09-01

The Department of Forensic Entomology (Institut de Recherche Criminelle de la Gendarmerie Nationale, France) was accredited by the French Committee of Accreditation (Cofrac's Healthcare section) in October 2007 on the basis of NF EN ISO/CEI 17025 standard. It was the first accreditation in this specific field of forensic sciences in France and in Europe. The present paper introduces the accreditation process in forensic entomology (FE) through the experience of the Department of Forensic Entomology. Based upon the identification of necrophagous insects and the study of their biology, FE must, as any other expertise work in forensic sciences, demonstrate integrity and good working practice to satisfy both the courts and the scientific community. FE does not, strictly speaking, follow an analytical method. This could explain why, to make up for a lack of appropriate quality reference, a specific documentation was drafted and written by the staff of the Department of Forensic Entomology in order to define working methods complying with quality standards (testing methods). A quality assurance system is laborious to set up and maintain and can be perceived as complex, time-consuming and never-ending. However, a survey performed in 2011 revealed that the accreditation process in the frame of expertise work has led to new well-defined working habits, based on an effort at transparency. It also requires constant questioning and a proactive approach, both profitable for customers (magistrates, investigators) and analysts (forensic entomologists).

Nematic fluctuations and resonance in iron-based superconductors

NASA Astrophysics Data System (ADS)

Gallais, Yann

The spontaneous appearance of nematicity, a state of matter that breaks rotation but not translation symmetry, is ubiquitous in many iron based superconductors (Fe SC), and has relevance for the cuprates as well. Here I will review recent electronic Raman scattering experiments which report the presence of critical nematic fluctuations in the charge channel in the tetragonal phase of several Fe SC systems. In electron doped Co-BaFe2As2 (Co-Ba122), these fluctuations extend over most of the superconducting dome. Their associated nematic susceptibility shows Curie-Weiss behavior, and its doping dependence suggests the presence of a nematic quantum critical point near optimal TC Similar nematic fluctuations are also observed in FeSe despite the absence of magnetic order, raising the question of the link between nematicity and magnetism in Fe SC. In FeSe I will further contrast the evolution of nematic fluctuations under isoelectronic S substitution and hydrostatic pressures up to 8 GPa, with only the former showing evidence for a nematic quantum critical point. In the superconducting state of Co-Ba122, I will show that a resonance emerges in the Raman spectra near the nematic quantum critical point. This nematic resonance is a clear fingerprint of the coupling between nematic fluctuations and Bogoliubov quasiparticles, and can be thought as the nematic counterpart of the spin resonance observed in neutron scattering experiments.

vicinity of the nucleus. Evidence of moderate, AGN-driven radio activity is also found in both sources. Based on the estimated stellar and black hole masses, the two sources lie on the local M_BH{-}M_bulge relation. To remain on this relation as they evolve, their star formation rate has to decrease or stop. Our results support evolutionary models that invoke radio feedback such as the star formation quenching mechanism, and suggest that such a mechanism might play a major role also in powerful AGNs.

It is concluded (a) that classical LTE line synthesis is able to reproduce with considerable accuracy the line profiles of late B and early A stars with T_e above about 9500 K, but that the LTE model with depth-independent microturbulence provides a very poor approximation for cooler A stars, (b) that curve-of-growth microturbulent velocities in A stars are related to directly detectable atmospheric velocity fields, and (c) that the discrepancies between calculated and observed line profiles in stars with temperatures in the vicinity of 8000 K are so large that abundances derived mainly from saturated lines may well contain significant errors. As a by-product, laboratory gf values for Fe II between 3800 and 5300 Angstroms have been combined to form a set of data optimized for internal consistency of the gf values.

The 'Teen Cafè' phenomenon grew out of an NSF-funded experiment to bring the Cafè Scientifique model for engagement of the public with science and scientists to high school teenagers. Cafè Scientifique New Mexico (cafènm.org), now in its seventh year, has proven highly popular with high school teens for much the same reason as for adult Cafè programs: the blend of socializing in an attractive venue and interaction with a scientist on an interesting science topic. Teen Cafés also include exploration of the topic with hands-on activities. The success of the model has led to the creation of the national Teen Science Cafè Network (teensciencecafe.org. This first year of the new program, four 'Founding Members' of the Network-- in Florida, Colorado, North Carolina, and the St. Louis, Missouri region--started up Teen Cafè programs. Each applied the model with a unique flair appropriate to local institutions and demographics. Each Member in the Network runs Cafès in multiple local venues. We are now gearing up for our second year, and the Network is growing. Our Teen Cafè topics have covered a very wide range, from belly-button biodiversity to cyber-security to patterns of mega-earthquakes to a day in the life of a teen dolphin to corals on acid to emergency room medicine to alternative fuel cars. Presenters have come from a great variety of local institutions. Though they are popular with teens because they are fun and interesting, our evaluations have demonstrated that the programs are having a significant impact on participating teens' understanding of the nature of science, the work that scientists do, and the importance of science to their daily lives. We are also having success in training scientists to communicate effectively with this public audience. Presenters report strong satisfaction with their resulting quality of science communication. A surprising number have reported that their experience with the program has led them to think in a new way about

Schuepbach, E.

2010-09-01

This contribution presents evolving good practice in disseminating the body of know-how, skills and competencies within the networked community of atmospheric scientists as established in ACCENT. The promotion of early-career scientists, and encouraging the next generation to move into the field were among the key issues addressed by the "Training and Education" programme in the European Network of Excellence in Atmospheric Composition Change (ACCENT). Dissemination avenues include a virtual knowledge train carrying the wealth of high-quality scientific learning material developed with experts involved in the ACCENT network. Learning opportunities on current research in atmospheric composition change in Europe were also created during face-to-face training workshops. Real-life examples of pressing air quality issues were addressed in meetings with stakeholder groups that offered opportunities for mutual learning in inspiring partnerships. In order to increase the expertise in atmospheric composition change across Europe, activities were organized with the general public (e.g., Café Scientifique), where the participating early-career scientists were confronted with questions from lay people. For interested teachers, didactic translations of compact overviews on air quality science topics developed in ACCENT offer links with the typical European science curriculum and go beyond school book content. Some of the educational events, methods and tools are described in a booklet published in 2009 ("We Care for Clean Air!", ISBN 978-88-95665-01-6). The electronic version and all training material can be downloaded from www.accent-network.org/portal/education - a valuable resource for teachers and learners around the globe.

This paper describes the software and equipment used at the Laboratoire Primaire du Temps et des Frequences du Bureau National de Metrologie (BNM-LPTF), Paris, France. Two H-masers in short baseline, one located at the BNM-LPTF and the other at the Laboratoire de l'Horloge Atomique du Centre National de la Recherche Scientifique (CNRS-LHA), Orsay, France, were computed in parallel with the BNM-LPTF software and with the BERNESE V 4.1 software. The comparison of the results issued from both computations shows an agreement within 100 ps (1 sigma). In addition, comparisons with the BNM-LPTF software were made over 10 days with the H-masers located at the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany, and another at the National Physical Laboratory (NPL), Teddington, United Kingdom. The data collected show that a modulation with an amplitude of 50 ps and a period of 700-800 ps affects the equipment of the NPL. In addition, these comparisons show that the noise of the instruments together with the environmental conditions at the PTB was higher than that of the NPL and the BNM-LPTF during the observation period. The best relative frequency stability obtained, in the BNM-LPTF/NPL comparison, is about 3x10(-15) for averaging periods between 6x10(4) s and 3x10(5) s. This result is in good agreement with the expected stability of H-masers. It demonstrates that the noise brought by the GPS carrier phase measurements can be averaged out at this level.

A new phase of activity of the Herbig Be star HD 200775 in 2001: Evidence for binarity

The results of high-resolution spectroscopy of the Herbig Be star HD 200775 obtained within the framework of a cooperative observing programme in 2000-2002 are presented. A new high-activity phase of the object's Hα line occurred in the middle of 2001 in full agreement with a 3.68-year periodicity predicted by Miroshnichenko et al. (\\cite{mirosh}). A complicated picture of the Hα line profile variability near the activity maximum phase turned out to be very similar to that observed during the previous one in 1997. Variations of the radial velocity with the activity phase are detected in He I, Si II, and S II photospheric lines. The observed phenomena are interpreted in the framework of a model in which the star, together with its gaseous envelope, is a component of an eccentric binary system. A preliminary orbital solution is derived, and the system's parameters are estimated from the radial velocity curves of the Hα emission line. We find that the orbital eccentricity is e ˜0.3, the mean companion separation is ˜1000 R⊙, and the secondary companion is most likely to be a ˜3.5 M⊙ pre-main sequence object. We emphasize the importance of coordinated spectroscopic and interferometric observations at different phases of the object's activity for further understanding the properties of the system.

Evidence for an Accretion Origin for the Outer Halo Globular Cluster System of M31

We use a sample of newly discovered globular clusters from the Pan-Andromeda Archaeological Survey (PAndAS) in combination with previously cataloged objects to map the spatial distribution of globular clusters in the M31 halo. At projected radii beyond ≈30 kpc, where large coherent stellar streams are readily distinguished in the field, there is a striking correlation between these features and the positions of the globular clusters. Adopting a simple Monte Carlo approach, we test the significance of this association by computing the probability that it could be due to the chance alignment of globular clusters smoothly distributed in the M31 halo. We find that the likelihood of this possibility is low, below 1%, and conclude that the observed spatial coincidence between globular clusters and multiple tidal debris streams in the outer halo of M31 reflects a genuine physical association. Our results imply that the majority of the remote globular cluster system of M31 has been assembled as a consequence of the accretion of cluster-bearing satellite galaxies. This constitutes the most direct evidence to date that the outer halo globular cluster populations in some galaxies are largely accreted.

The northwestern Mediterranean subduction systems underwent an important phase of reorganization between Late Cretaceous and Eocene. The mode and timing of this reorganization are still under debate. Great uncertainties mainly derive from the poorly preserved record of the early phases of orogenic evolution in both the Alps and Pyrenees and the distruction of the orogenic system between the Pyrenees and Alps by the Oligo-Miocene opening of the Gulf of Lion due to backarc rifting. Vestiges are nevertheless preserved in the Pyreneo-Provençal fold-and-thrust belt and associated basins in southern France and Corsica-Sardinia. In this work we first review published plate kinematic models for Iberia, Apulia and Europe from 83 Ma, focusing in particular on the restoration of the Corso-Sardinia block using the free software GPlates. Second, we characterize the Upper Cretaceous to Eocene depositional systems at the junction between the Alps, Pyrenees and Apennines, reviewing previous paleogeographic restorations for the Western Alpine and Eastern Pyrenean foreland basins. Last, we compare the kinematic models with reconstructed basin dynamics. We critically assess the implications of newly proposed paleogeographic reconstructions (at 83, 65, 50, 37 and 30 Ma) for the validity of various plate kinematic models. The information derived from the sedimentary basins help to define the mode and timing of the subduction reorganization that occurred between 83 and 30 Ma in the northwestern Mediterranean.

Aims: In this work we derive new precise and homogeneous parameters for 37 stars with planets. For this purpose, we analyze high resolution spectra obtained by the NARVAL spectrograph for a sample composed of bright planet host stars in the northern hemisphere. The new parameters are included in the SWEET-Cat online catalogue. Methods: To ensure that the catalogue is homogeneous, we use our standard spectroscopic analysis procedure, ARES+MOOG, to derive effective temperatures, surface gravities, and metallicities. These spectroscopic stellar parameters are then used as input to compute the stellar mass and radius, which are fundamental for the derivation of the planetary mass and radius. Results: We show that the spectroscopic parameters, masses, and radii are generally in good agreement with the values available in online databases of exoplanets. There are some exceptions, especially for the evolved stars. These are analyzed in detail focusing on the effect of the stellar mass on the derived planetary mass. Conclusions: We conclude that the stellar mass estimations for giant stars should be managed with extreme caution when using them to compute the planetary masses. We report examples within this sample where the differences in planetary mass can be as high as 100% in the most extreme cases. Based on observations obtained at the Telescope Bernard Lyot (USR5026) operated by the Observatoire Midi-Pyrénées and the Institut National des Science de l'Univers of the Centre National de la Recherche Scientifique of France (Run ID L131N11 - OPTICON_2013A_027).

Le quatrième colloque Rayons X et Matière (RX 2001) s'est tenu à Strasbourg du 4 au 7 décembre 2001. Comme lors des colloques précédents (1995, 1997 et 1999) nous avons pu réunir de nombreux chercheurs, industriels et constructeurs concernés par la caractérisation des matériaux. Cette manifestation qui se déroule tous les deux ans a pour objectifs de rendre compte périodiquement des avancées faites dans le domaine des techniques X et plus particulièrement de l'ingénierie des surfaces. Cette année nous avons ajouté deux nouveaux thèmes : étude des nanomatériaux et techniques des microfaisceaux. André GUINIER était avec nous lors du premier colloque (colloque 1995, consacré à la commémoration du centenaire de la découverte des rayons X). Nous sommes attristés par son décès et nous lui dédions le Colloque RX 2001. Les premiers articles de cet ouvrage rappellent sa vie de scientifique et ses principaux travaux. En même temps que nous écrivons ces quelques lignes, nous nous préparons à lancer le colloque RX 2003. Ces colloques ont lieu grâce à la participation constante des chercheurs et l'engagement des constructeurs et distributeurs de matériels ; nous les en remercions vivement et nous leur donnons rendez-vous à Strasbourg, en décembre 2003.

L'École Thématique “Structure et Dynamique des Systèmes Désordonnés” [1] s'inscrit dans le cadre des écoles organisées sous l'impulsion de la Société Française de la Neutronique (SFN). Elle s'est deroulée en mai 2002 sur la Presqu'île de Giens (Var) en première partie des 11émes Journées de la Diffusion Neutronique. L'Édition de ces cours constitue ainsi le cinquième ouvrage introduisant les techniques neutroniques et leurs apports à differentes thématiques [2]. Le désordre est un facteur déterminant pour pratiquement toutes les propriétés des matériaux. Il est inhérent dans les matériaux amorphes ou liquides, mais il détermine également les propriétés mécaniques et électroniques d'autres composés d'importance technologique comme les matériaux métalliques, dont l'aspect “désordonné” est moins évident. Le désordre enfin joue un rôle essentiel dans tout ce que touche à la vie. En fait, il est difficile d'imaginer des systèmes, à part quelques exceptions rares comme l'hélium ou le silicium de haute pureté, où il n'y ait pas de désordre. En dehors de cet aspect pratique, la description scientifique du désordre atomique pose toujours des problèmes fondamentaux faute de concepts pertinents. Une des tâches importantes du scientifique ou de l'ingenieur est de préciser quel genre de désordre existe à une échelle d'espace et de temps donnée. Un materiau peut très bien être homogène à l'échelle atomique et présenter des défauts ou des hétrogéneité visibles à l'œil et inversement. De même, un système désordonné à un instant donné, peut apparaître ordonné si on moyenne dans le temps. Les techniques de diffusion des neutrons sont idéales pour aborder ces questions. Les neutrons sondent directement les noyaux et ont à la fois des longueurs d'ondes proches des distances inter atomiques et des énergies avoisinant celles des excitations élémentaires de la matière condensée. Ils permettent ainsi

The efficacy of tea seed oil to clean foundation and eyeliner was evaluated. The safe and efficient tea seed oil makeup remover was developed. In vitro cleansing efficacy of makeup remover was UV-spectrophotometric validated. The stability evaluation by means of accelerated stability test was conducted. In vitro and in vivo cleansing efficacy of the removers was conducted in a comparison with benchmark majorly containing olive oil. Tea seed oil cleaned 90.64±4.56% of foundation and 87.62±8.35% of eyeliner. The stable with most appropriate textures base was incorporated with tea seed oil. Three tea seed oil removers (50, 55 and 60%) were stabled. The 60% tea seed oil remover significantly removed foundation better than others (94.48±3.37%; P<0.001) and the benchmark (92.32±1.33%), but insignificant removed eyeliner (87.50±5.15%; P=0.059). Tea seed oil remover caused none of skin irritation as examined in 20 human volunteers. A single-blind, randomized control exhibited that the tea seed oil remover gained a better preference over the benchmark (75.42±8.10 and 70.00±7.78%; P=0.974). The safe and efficient tea seed oil makeup removers had been developed. The consumers' choices towards the makeup remover containing the bio-oils are widen. In vitro cleansing efficacy during the course of makeup remover development using UV-spectrophotometric method feasible for pharmaceutic industries is encouraged.

The year 2016 will be pivotal for the evaluation of French medical students with the introduction of the first computerized National Ranking Test (ECNi). The SIDES, online electronic system for medical student evaluation, was created for this purpose. All the universities have already organized faculty exams but few a joint computerized ranking test at several universities simultaneously. We report our experience on the organization of a mock ECNi by universities Paris Descartes, Paris Diderot and Paris 13. Docimological, administrative and technical working groups were created to organize this ECNi. Students in their fifth year of medical studies, who will be the first students to sit for the official ECNi in 2016, were invited to attend this mock exam that represented more than 50% of what will be proposed in 2016. A final electronic questionnaire allowed a docimological and organizational evaluation by students. An analysis of ratings and rankings and their distribution on a 1000-point scale were performed. Sixty-four percent of enrolled students (i.e., 654) attended the three half-day exams. No difference in total score and ranking between the three universities was observed. Students' feedback was extremely positive. Normalized over 1000 points, 99% of students were scored on 300 points only. Progressive clinical cases were the most discriminating test. The organization of a mock ECNi involving multiple universities was a docimological and technical success but required an important administrative, technical and teaching investment.

[Bell's palsy].

PubMed

Prud'hon, S; Kubis, N

2018-03-30

Idiopathic peripheral facial palsy, also named Bell's palsy, is the most common cause of peripheral facial palsy in adults. Although it is considered as a benign condition, its social and psychological impact can be dramatic, especially in the case of incomplete recovery. The main pathophysiological hypothesis is the reactivation of HSV 1 virus in the geniculate ganglia, leading to nerve edema and its compression through the petrosal bone. Patients experience an acute (less than 24 hours) motor deficit involving ipsilateral muscles of the upper and lower face and reaching its peak within the first three days. Frequently, symptoms are preceded or accompanied by retro-auricular pain and/or ipsilateral face numbness. Diagnosis is usually clinical but one should look for negative signs to eliminate central facial palsy or peripheral facial palsy secondary to infectious, neoplastic or autoimmune diseases. About 75% of the patients will experience spontaneous full recovery, this rate can be improved with oral corticotherapy when introduced within the first 72 hours. To date, no benefit has been demonstrated by adding an antiviral treatment. Hemifacial spasms (involuntary muscles contractions of the hemiface) or syncinesia (involuntary muscles contractions elicited by voluntary ones, due to aberrant reinnervation) may complicate the disease's course. Electroneuromyography can be useful at different stages: it can first reveal the early conduction bloc, then estimate the axonal loss, then bring evidence of the reinnervation process and, lastly, help for the diagnosis of complications.

Madagascar's health care system has operated without formal hospital pharmacies for more than two decades. The gradual integration of pharmacists in public hospitals since 2012 will allow the structuring of this field. This study was conducted to characterize the current situation regarding all aspects relating to the general functioning of hospital pharmacies and the services provided. This qualitative research used semi-structured interviews. Interviewees' perceptions about the general organization and functioning of hospital pharmacies and details on services provided were collected. The 16 interviewees were Ministry of Health staff members involved in hospital pharmacy, hospital directors, medical staff members and hospital pharmacy managers. Interviews were recorded, translated into French if conducted in Malagasy, and fully transcribed. Verbatim transcripts were coded according to the themes of hospital pharmacy and topical content analysis was performed. The principal issue perceived by interviewees was the heterogeneity of the system in terms of technical and financing management, with a main impact on the restocking of pharmaceutical products. The drug supply chain is not under control: no internal procedure has been established for the selection of pharmaceutical products, the quantification of needs is complex, stock management is difficult to supervise, a standard prescription protocol is lacking, dispensing is performed by unqualified staff, no pharmaceutical preparation is manufactured in the hospitals and administration occurs without pharmaceutical support. Progressive structuring of efficient hospital pharmacy services using the Basel statements for the future of hospital pharmacy is urgently needed to improve health care in Madagascar.

The objective of this work is to show the feasibility of manufacturing from a spray drying process particles containing immunoglobulin G capable of being administered by inhalation via a pressurized metered dose inhaler. Spray drying were made from aqueous solutions containing IgG and two types of excipients, mannitol and trehalose, with two ratios: 25% w/w and 75%w/w. The physicochemical and aerodynamic properties of the powders obtained were characterized just after manufacturing and after 1 month of storage at 40°C/75% RH according to criteria defined as needed to satisfy an inhaled formulation with a pressurized metered dose inhaler. Maintain of the biological activity and the structure of IgG after atomization was also tested by slot blot and circular dichroism. All spray-dried powders presented a median diameter lower than 5μm. The powders atomized with trehalose showed a solid state more stable than those atomized with mannitol. All atomized powders were in the form of wrinkled particles regardless the nature and the ratios of excipients. The results showed that the aerosolisation properties were compliant with the target, independently of the excipient used at a ratio of 25% w/w IgG-excipient. Moreover, the addition of excipient during the atomization process the denaturation of IgG was limited. This study showed that the use of trehalose as excipient could satisfy the requirements of an inhaled formulation with a pressurized metered dose inhaler.

Paraneoplastic Cushing's syndrome is a rare cause of endogenous hypercortisolism attributable to ectopic ACTH secretion by non-pituitary tumors. Imaging and biochemical results are often inconclusive and differential diagnosis with Cushing's disease can then be challenging. Moreover, these tumors may be occult and difficult to find and thus the need of new imaging tools such as (18)FDG-PET scan and (18)DOPA-PET scan. We report a 50-year-old man who presented with very aggressive clinical features related to Cushing's syndrome. Biological work-up confirmed the hypercortisolism and was consistent with an ectopic ACTH secretion. Conventional localization techniques failed to show any tumor and bilateral adrenalectomy was performed because of life-threatening complications. Two years later, thoracic computed tomography reveals an 11 mm mass in the left lower pulmonary lobe, (18)FDG-PET scan found a non-specific mild hypermetabolism of the lung nodule, and the (18)DOPA-PET scan confirmed the high uptake of this nodule suggesting an endocrine carcinoma. Histology confirmed a typical carcinoid tumor. The tumor cells stained positive for ACTH, CD56, chromogranin and synaptophysin. This case illustrates the dilemma between the need for morphological diagnosis of the ectopic ACTH source and control of the life-threatening hypercortisolism. (18)FDG-PET scan and (18)DOPA-PET scan should be considered early as a secondary diagnostic tool when conventional imagery fails to show any tumor.

Streptococcus pneumoniae can cause invasive infections. Incidence and severity are linked to patients' risk factors. Due to the resistance to leading antibiotics, the anti-pneumococcal vaccination has become a major public health issue. The purpose of this survey was to evaluate the anti-pneumococcal vaccine coverage in a population of adults with risk factors. This was a prospective study that included patients with at least one recommendation for pneumococcal vaccination as indicated by the Weekly Epidemiological Bulletin (BEH), to which three further US recommendations were added (diabetes, obesity and age>65years). One hundred and thirty-four patients with an average age of 70 years were included. The physician could only confirm 68 % of the patients' vaccination status. Vaccination coverage as recommended by the BEH board was 30 % (n=54). All HIV patients were vaccinated (n=2) and the vaccination coverage was 75 % (n=8) for patients treated for autoimmune diseases and only 10 % (n=20) for patients treated with chemotherapy. Patients with no vaccination didn't know the existence of the vaccine or didn't know that vaccination was recommended to them. This study has highlighted a deficit in pneumococcal vaccination coverage and a high level of ignorance of the existence of recommended vaccination. In addition to awareness campaign for patients and caregiver training, the expansion of the vaccine e-book utilization could improve the vaccination status.

Deep dermatophytosis is a severe and sometimes life-threatening fungal infection caused by dermatophytes. It is characterized by extensive dermal and subcutaneous tissue invasion and by frequent dissemination to the lymph nodes and, occasionally, the central nervous system. The condition is different from common superficial dermatophyte infection and has been reported in patients with no known immunodeficiency. Patients are mostly from North African, consanguineous, multiplex families, which strongly suggests a mendelian genetic cause. We studied the clinical features of deep dermatophytosis in 17 patients with no known immunodeficiency from eight unrelated Tunisian, Algerian, and Moroccan families. Because CARD9 (caspase recruitment domain-containing protein 9) deficiency has been reported in an Iranian family with invasive fungal infections, we also sequenced CARD9 in the patients. Four patients died, at 28, 29, 37, and 39 years of age, with clinically active deep dermatophytosis. No other severe infections, fungal or otherwise, were reported in the surviving patients, who ranged in age from 37 to 75 years. The 15 Algerian and Tunisian patients, from seven unrelated families, had a homozygous Q289X CARD9 allele, due to a founder effect. The 2 Moroccan siblings were homozygous for the R101C CARD9 allele. Both alleles are rare deleterious variants. The familial segregation of these alleles was consistent with autosomal recessive inheritance and complete clinical penetrance. All the patients with deep dermatophytosis had autosomal recessive CARD9 deficiency. Deep dermatophytosis appears to be an important clinical manifestation of CARD9 deficiency.

The Ocean Topography Experiment (TOPEX/Poseidon) mission is designed to determine the topography of the Earth's sea surface over a 3-year period, beginning shortly after launch in July 1992. TOPEX/Poseidon is a joint venture between the United States National Aeronautics and Space Administration (NASA) and the French Centre Nationale d'Etudes Spatiales. The Jet Propulsion Laboratory is NASA's TOPEX/Poseidon project center. The Tracking and Data Relay Satellite System (TDRSS) will nominally be used to support the day-to-day orbit determination aspects of the mission. Due to its extensive experience with TDRSS tracking data, the NASA Goddard Space Flight Center (GSFC) Flight Dynamics Facility (FDF) will receive and process TDRSS observational data. To fulfill the scientific goals of the mission, it is necessary to achieve and maintain a very precise orbit. The most stringent accuracy requirements are associated with planning and evaluating orbit maneuvers, which will place the spacecraft in its mission orbit and maintain the required ground track. To determine if the FDF can meet the TOPEX/Poseidon maneuver accuracy requirements, covariance analysis was undertaken with the Orbit Determination Error Analysis System (ODEAS). The covariance analysis addressed many aspects of TOPEX/Poseidon orbit determination, including arc length, force models, and other processing options. The most recent analysis has focused on determining the size of the geopotential field necessary to meet the maneuver support requirements. Analysis was undertaken with the full 50 x 50 Goddard Earth Model (GEM) T3 field as well as smaller representations of this model.

The economic impact of therapeutic innovations on the hospital patient management cannot be easily estimated. The objective of this study is to illustrate the use of a Delphi survey as a support tool to identify the changes following the use of idarucizumab in dabigatran-treated patients with uncontrolled/life-threatening bleeding or who required emergency surgery/urgent procedures. The Delphi questionnaires have been administrated to 8 emergency physicians or anesthetists from 6 different hospital centers. Following the answers, an economic valorization has been carried out on every parameter on which a consensus was reached (at least 4 answers showing an identical trend). A mean management cost for each etiology with and without the use of idarucizumab has thus been identified. For gastro-intestinal and other life-threatening bleedings (excepted intracranial bleedings), the total management cost of the hospital stay was respectively 6058 € (-35%) and 6219 € (-34%) following the use of the reversal agent. The hospital management cost for intracranial bleeding is slightly increasing to 9790 € (+3%). The cost of a stay for emergency surgery decreases to 6962€ (-2%). This study shows a positive economic impact following the use of the dabigatran-specific reversal agent for patients with uncontrolled/life-threatening bleeding excepted in the case of intracranial bleeding. Moreover, it points out that a Delphi survey is an easy way to predict the hospital economic impact of a therapeutic innovation when no other evaluation is possible.

Experimental and epidemiologic studies have yielded conflicting results on the relation between vitamin C intake and breast cancer risk. We investigated the relation between vitamin C supplement intake and breast cancer risk while considering dietary vitamin C intake. Between 1995 and 2008, 2482 invasive breast cancer cases occurred in 57,403 postmenopausal women from the Etude Epidémiologique auprès de femmes de la Mutuelle Générale de l'Education Nationale (E3N) prospective cohort during 581,085 person-years. We estimated vitamin C intake from foods with the use of a validated food-frequency questionnaire that was sent to subjects in 1993-1995 and vitamin C supplement use via questionnaires sent in 1995, 2000, 2002, and 2005. Multivariable HRs (95% CIs) for primary invasive breast cancer were estimated with the use of Cox regression models. All statistical tests were 2-sided. Vitamin C supplement use (ever compared with never) was not associated with breast cancer risk overall; it was associated with higher breast cancer risk in women in the fourth quartile of vitamin C intake from foods (HR: 1.32; 95% CI: 1.04, 1.67) but not in other quartiles of dietary vitamin C intake (P-interaction = 0.03). We observed that vitamin C supplement use was associated with increased postmenopausal breast cancer risk in women with high vitamin C intake from foods. Our data suggest a potential U- or J-shaped relation between total vitamin C intake and postmenopausal breast cancer risk that deserves further investigation. © 2016 American Society for Nutrition.

The Mysterious sdO X-ray Binary BD+37°442

Pulsed X-ray emission in the luminous, helium-rich sdO BD +37°442 has recently been discovered (La Palombara et al. 2012). It was suggested that the sdO star has a neutron star or white dwarf companion with a spin period of 19.2 s. After HD 49798, which has a massive white dwarf companion spinning at 13.2 s in an 1.55 day orbit, this is only the second O-type subdwarf from which X-ray emission has been detected. We report preliminary results of our ongoing campaign to obtain time-resolved high-resolution spectroscopy using the CAFE instrument at Calar Alto observatory and SARG at the Telescopio Nationale Galileo. Atmospheric parameters were derived via a quantitative NLTE spectral analysis. The line fits hint at an unusually large projected rotation velocity. Therefore it seemed likely that BD +37°442 is a binary similar to HD 49798 and that the orbital period is also similar. The level of X-ray emission from BD +37°442 could be explained by accretion from the sdO wind by a neutron star orbiting at a period of less than ten days. Hence, we embarked on radial velocity monitoring in order to derive the binary parameters of the BD+37°442 system and obtained 41 spectra spread out over several month in 2012. Unlike for HD 49798, no radial velocity variations were found and, hence, there is no dynamical evidence for the existence of a compact companion yet. The origin of the pulsed X-ray emission remains as a mystery.

The main objective was to assess the position of Quebec pharmaceutical community about pharmaceutical ethics statements. The second objective was to compare the level of agreement of pharmacy students and hospitals pharmacists. Survey conducted one day given in 2012 and 2013 for students in 2013 and from 29/08/2014 to 02/09/2014 for pharmacists. A questionnaire of eight themes and 43 statements was developed: training and education (5 questions), clinical research (7) advertising and marketing (5) evaluation (5) dispensing medication (4), pharmaceutical care (9) economic aspect (6) and code of ethics (2). A Likert scale with four choices was used to measure the level of agreement. The primary outcome was the difference between the level of agreement of pharmacy students and hospital pharmacists. The Chi 2  test was used. A total of 347 students and 398 pharmacists responded to the survey. There was a statistically significant difference regarding the level of agreement with 28 statements on 43. The differences focused on eight themes of the questionnaire, or training and education (3/5 significantly different questions), clinical research (2/7), advertising and marketing (2/5), Evaluation (4/5) dispensing medication (4/4), pharmaceutical care (5/9), economic aspect (6/6) and ethics (2/2). This study shows that there is a difference between pharmacists and pharmacy students about pharmaceutical ethics statements. Copyright © 2016 Académie Nationale de Pharmacie.

Adaptive Automation (AA) is a promising approach to keep the task workload demand within appropriate levels in order to avoid both the under - and over-load conditions, hence enhancing the overall performance and safety of the human-machine system. The main issue on the use of AA is how to trigger the AA solutions without affecting the operative task. In this regard, passive Brain-Computer Interface (pBCI) systems are a good candidate to activate automation, since they are able to gather information about the covert behavior (e.g., mental workload) of a subject by analyzing its neurophysiological signals (i.e., brain activity), and without interfering with the ongoing operational activity. We proposed a pBCI system able to trigger AA solutions integrated in a realistic Air Traffic Management (ATM) research simulator developed and hosted at ENAC (É cole Nationale de l'Aviation Civile of Toulouse, France). Twelve Air Traffic Controller (ATCO) students have been involved in the experiment and they have been asked to perform ATM scenarios with and without the support of the AA solutions. Results demonstrated the effectiveness of the proposed pBCI system, since it enabled the AA mostly during the high-demanding conditions (i.e., overload situations) inducing a reduction of the mental workload under which the ATCOs were operating. On the contrary, as desired, the AA was not activated when workload level was under the threshold, to prevent too low demanding conditions that could bring the operator's workload level toward potentially dangerous conditions of underload.

The diagnostic value of selective anorexia is debated. Some authors have suggested an association between meat aversion and cancer, but most do not use it as a diagnostic tool. We aimed to characterize anorexia of different diseases to search for an association between selective aversions and diagnostic groups. All the patients admitted to three departments of a teaching hospital were included consecutively for 22months if they had more than 10 % weight loss in less than one year. Patients were excluded if history taking was not reliable, or if they suffered from anorexia nervosa. We compiled diagnoses at discharge and validated them six months later. We used logistic regression to identify independent factors associated with selective anorexia. Inclusion criteria were met in 106patients (female 44 %, median age 65years). Most frequent diagnoses were: cancer (36 %), infection (35 %), digestive diseases (19 %), non organic diseases (21 %). Recent selective anorexia was found in 46 % of the cases. It was significantly associated with female gender (P=0.002), marginally with young age (P=0.069) and long duration of weight loss (P=0.079). Opioid use at admission was negatively associated with selective anorexia (P=0.001). No specific diagnostic category was found to be associated. Selective anorexia does not appear to be a useful symptom to investigate pathological weight loss. It behaves more like a non-specific reactivation by current disease of earlier latent personal food aversions. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

Since 2009, single-use (SU) ancillaries for total knee arthroplasty (TKA) and total hip arthroplasty (THA) have been marketed to replace reusable ancillaries. The concept is not innovative but their use in orthopedics is still uncommon. An assessment has been done for the use of SU ancillary in Assistance publique-hôpitaux de Paris with the consequences for the patient, the surgeon and the hospital. A technical and a clinical review has been done with those devices in 2015. The economic and organizational impacts were identified and submitted for opinion to committee experts in orthopedics. Three SU ancillaries are commercialized. No clinical studies are currently available. There is no reimbursement for SU ancillaries whereas reusable ancillaries are included in prosthesis reimbursement price. Although SU ancillaries (TKA and THA) saving costs for sterilization, the annual additional budget estimated for their purchase would approximately be 2.5 times higher. Nevertheless, indirect savings could be also considered in the long-term period (global costs for sterilization, volume effect…). For the same quality, according to the experts, organizational impacts are low for the patient and the surgeon but potentially important for the hospital, the nursing and pharmaceutical staff, and logistical activities. On logistic, clinical and financial aspects, SU ancillaries need more evaluation. The switch to SU ancillaries allows saving sterilization costs and time, and provided an immediate mobilization of the equipment but their interest must be demonstrated by clinical and economic data.

Episodes of acquired bradykinin-mediated angioedema due to angiotensin-converting enzyme (ACE) inhibitors may result in fatal outcomes. There is no consensus regarding emergency pharmacological management of these episodes. Treatment options include icatibant and C1INH concentrate. Tranexamic acid is administered for moderate episodes. Its efficacy in the treatment of ACE inhibitor-induced episodes of angioedema is not established. The aim of this retrospective study is to assess the benefits of emergency tranexamic acid administration in the management of ACE inhibitor-induced episodes of angioedema. Retrospective analysis of the medical files of patients who consulted between 2010 and 2016 in two French tertiary care hospitals for a bradykinic angioedema attributed to an ACE treatment. All of them had received tranexamic acid as a first line treatment. Thirty three patients who had experienced severe episode of angioedema were included. Twenty seven patients showed significant improvement when treated with tranexamic acid alone. The six remaining patients were treated with icatibant (5/33) or C1INH concentrate (1/33), due to partial improvement after tranexamic acid therapy. None of the patients were intubated, no fatalities were recorded and no side effects were reported. Tranexamic acid is an easily accessible and affordable therapy that may provide effective treatment for ACE inhibitor-induced episodes of angioedema. It may help while waiting for a more specific treatment (icatibant and C1INH concentrate) that is at times unavailable in emergency departments.

Orally administered medications may interact with various fruits, vegetables, herbal medicines, functional foods or dietary supplements. Drug-food interactions, which are mostly unknown from prescribers, including internists, may be responsible for changes in drug plasma concentrations, which may decrease efficacy or led to sometimes life-threatening toxicity. Aging, concomitant medications, transplant recipients, patients with cancer, malnutrition, HIV infection and those receiving enteral or parenteral feeding are at increased risk of drug-food interactions. This review focused on the most clinically relevant drug-food interactions, including those with grapefruit juice, Saint-John's Wort, enteral or parenteral nutrition, their respective consequences in the clinical setting in order to provide thoughtful information for internists in their routine clinical practice. Specific clinical settings are also detailed, such as the Ramadan or multiple medications especially in elderly patients. Drug-food interactions are also presented with respect to the main therapeutic families, including the non-steroidal anti-inflammatory drugs, analgesics, cardiovascular medications, warfarin as well as new oral anticoagulants, anticancer drugs and immunosuppressant medications. Considerable effort has been achieved to a better understanding of food-drug interactions and increase clinicians' ability to anticipate their occurrence and consequences in clinical practice. Describing the frequency of relevant food-drug interactions in internal medicine is paramount in order to optimize patient care and drug dosing on an individual basis as well as to increase patients and doctors information.

Can shale safely host US nuclear waste?

"Even as cleanup efforts after Japan’s Fukushima disaster offer a stark reminder of the spent nuclear fuel (SNF) stored at nuclear plants worldwide, the decision in 2009 to scrap Yucca Mountain as a permanent disposal site has dimmed hope for a repository for SNF and other high-level nuclear waste (HLW) in the United States anytime soon. About 70,000 metric tons of SNF are now in pool or dry cask storage at 75 sites across the United States [Government Accountability Office, 2012], and uncertainty about its fate is hobbling future development of nuclear power, increasing costs for utilities, and creating a liability for American taxpayers [Blue Ribbon Commission on America’s Nuclear Future, 2012].However, abandoning Yucca Mountain could also result in broadening geologic options for hosting America’s nuclear waste. Shales and other argillaceous formations (mudrocks, clays, and similar clay-rich media) have been absent from the U.S. repository program. In contrast, France, Switzerland, and Belgium are now planning repositories in argillaceous formations after extensive research in underground laboratories on the safety and feasibility of such an approach [Blue Ribbon Commission on America’s Nuclear Future, 2012; Nationale Genossenschaft für die Lagerung radioaktiver Abfälle (NAGRA), 2010; Organisme national des déchets radioactifs et des matières fissiles enrichies, 2011]. Other nations, notably Japan, Canada, and the United Kingdom, are studying argillaceous formations or may consider them in their siting programs [Japan Atomic Energy Agency, 2012; Nuclear Waste Management Organization (NWMO), (2011a); Powell et al., 2010]."

Nocardiosis are uncommon. The diagnosis may be difficult, with significant morbidity and mortality, often occurring on frail patients. Few data are available in France. A retrospective single center study was conducted from 2002 to 2014 and included all patients with at least one positive microbiological sample for Nocardia with a follow-up in our hospital. Nineteen patients, including 15 men, were included with a mean age of 58 years (25-85). Seventeen had a risk factor (lung diseases [13], corticosteroids [12], solid neoplasia [2], HIV infection [2], diabetes mellitus [3], kidney transplant [2], lymphopenia [1]). Infections' locations were: pulmonary (12), brain (3), skin (2), lymph node (1) and corneal (1). The slow growth leads to a median of 35 days for a positive result (3-95). Nine species were identified. Fifteen patients (79%) received one or more lines of antibiotics including: cotrimoxazole (9), amoxicillin (7) cefotaxime/ceftriaxone (7) imipenem (3), or amikacin (3). The average duration of antibiotic therapy was 207 days. Four patients did not receive antibiotics due to a late result or a bacterial co-infection masking nocardiosis. Five patients died (26%) including 2 with cerebral nocardiosis. Six patients were cured, 4 suffered a relapse, 4 had an unknown evolution, and 1 was still treated. Our study shows that nocardiosis is a disease difficult to treat. A better understanding of this type of infection is necessary.

The 4-year EXAEDRE (EXploiting new Atmospheric Electricity Data for Research and the Environment; Oct 2016-Sept 2020) project is sponsored by the French Science Foundation ANR (Agence Nationale de la Recherche). This project is a French contribution to the HyMeX (HYdrological cycle in the Mediterranean EXperiment) program. The EXAEDRE activities rely on innovative multi-disciplinary and state of the art instrumentation and modeling tools to provide a comprehensive description of the electrical activity in thunderstorms. The EXAEDRE observational part is based on i) existing lightning records collected during HyMeX Special Observation Period (SOP1; Sept-Nov 2012), and permanent lightning observations provided by the research Lightning Mapping Array SAETTA and the operational Météorage lightning locating systems, ii) additional lightning observations mapped with a new VHF interferometer especially developed within the EXAEDRE project, and iii) a dedicated airborne campaign over Corsica. The modeling part of the EXAEDRE project exploits the electrification and lightning schemes developed in the cloud resolving model MesoNH and promotes an innovative technique of flash data assimilation in the french operational model AROME of Météo-France. An overview of the EXAEDRE project will be given with an emphasis on the instrumental, observational and modeling activities performed during the 1st year of the project. The preparation of the EXAEDRE airborne campaign scheduled for September 2018 over Corsica will then be discussed. Acknowledgements.

A biosimilar is a biological medicinal product claimed to be similar to a reference biological medicinal product. Its development plan includes studies comparing it with the reference product in order to confirm its similarity in terms of quality, preclinical safety, clinical efficacy, and clinical safety, including immunogenicity. Biosimilars differ from generics both in their molecular complexity and in the specific requirements that apply to them. Since patents on many biological medicinal products will expire within the next 5 years in major therapeutic areas such as oncology, rheumatology and gastroenterology and as those products are so costly to the French national health insurance system, the availability of biosimilars would have a considerable economic impact. The round table has issued a number of recommendations intended to ensure that the upcoming arrival of biosimilars on the market is a success, in which prescribing physicians would have a central role in informing and reassuring patients, an efficient monitoring of the patients treated with biologicals would be set up and time to market for biosimilars would be speeded up. © 2015 Société Française de Pharmacologie et de Thérapeutique.

The aim of the study was to demonstrate the noninferiority of polyacrylamide hydrogel (PH) vs. polylactic acid (PLA) for the treatment of facial lipoatrophy in HIV-infected adults. A randomized, blinded, multicentre, noninferiority 96-week study was carried out. Patients with facial lipoatrophy were randomly assigned to receive intradermal injections with PH or PLA, and were blinded to the filler. The primary efficacy endpoint was patient satisfaction at week 48 assessed using a visual analogue scale score (VAS). Secondary efficacy end-points included cheek thickness and skin-fold, lipoatrophy grading and quality of life. Safety was assessed by the reporting of adverse events. A total of 148 patients were included in the study; 93% were men, the median age was 47 years, the median CD4 count was 528 cells/μL, and the median duration of antiretroviral therapy was 12 years. Mean VAS increased from 2.8 at baseline to 7.1 and 7.5 in the PLA and PH arms, respectively, at week 48 (P=0.0002 for noninferiority) and was sustained at week 96 (6.7 and 7.9 in the PLA and PH arms, respectively; P=0.003 for noninferiority). Cheek thickness and skin-fold increases and lipoatrophy improvement were similar in the two arms. Quality of life remained unchanged or improved depending on the questionnaire used. In injected patients, subcutaneous nodules emerged in 28 (41%) and 26 (37%) patients in the PLA and PH arms, respectively (P=0.73). Four patients in the PH arm developed severe inflammatory nodules, a median of 17 months after the last injection. PH and PLA have similar efficacies in the treatment of facial lipoatrophy, but PH may be associated with more delayed inflammatory nodules. © 2013 British HIV Association.

OSO 8 observations of the profiles of the resonance lines of H I, Mg II, and Ca II obtained with the Laboratorie de Physique Stellaire et Planetaire de Centre National de la Recherche Scientifique (LPSP-CNRS) spectrometer (by A.S.) and of C IV obtained with the University of Colorado (CU) spectrometer (by B.W.L.) for a large quiet sunspot (1975 November 16--17) are analyzed along with near-simultaneous ground-based Stokes measurements obtained in a collaborative arrangement with L. L. House and T. Baur (HAO-NCAR) to yield an umbral chromosphere and transition region model. Features of this model include: (1) a chromosphere that ismore » effectively thin in the important chromsopheric resonance lines of H I and Mg II and saturated in Ca II; (2) an upper chromospheric structure similar to quiet-Sun models; (3) penetration of the sunspot photospheric ''cooling wave'' to higher altitudes in the sunspot chromosphere than in quiet-Sun models, i.e., a more extended temperature minimum region in the sunspot atomphere; (4) a lower pressure corona above the sunspot umbra than above a typical quiet region; (5) very low nonthermal broadening in the umbral chromosphere; (6) a moderately strong downdraft; (7) chromospheric radiative loss rates not significantly different from their corresponding quiet-Sun values; (8) a temperature gradient in the transitons region near 10/sup 5/ Kapprox.0.1 times the corresponding quiet-Sun value. The Balmer continuum radiation from the photospheric areas outside the sunspot umbra controls the hydrogen ionization, and hence the electron density, in the chromosphere above the umbra.« less

Study of selective heating at ion cyclotron resonance for the plasma separation process

1995-12-01

The plasma separation process by ion cyclotron resonance heating (ICRH) is studied both theoretically and experimentally on two devices: the first one called ERIC (Ion Cyclotron Resonance Experiment) at Saclay (France) [P. Louvet, Proceedings of the 2nd Workshop on Separation Phenomena in Liquids and Gases, Versailles, France, 1989, edited by P. Louvet, P. Noe, and Soubbaramayer (Centre d'Etudes Nucléaires de Saclay and Cité Scientifique Parcs et Technopoles, Ile de France Sud, France, 1989), Vol. 1, p. 5] and the other one named SIRENA at the Kurchatov Institute, Moscow, Russia [A. I. Karchevskii et al., Plasma Phys. Rep. 19, 214 (1993)]. The radio frequency (RF) transversal magnetic field is measured by a magnetic probe both in plasma and vacuum and its Fourier spectrum versus the axial wave number kz is obtained. These results are in agreement with the electromagnetic (EM) field calculation model based on resolution of Maxwell equations by a time-harmonic scheme studied here. Various axial boundary conditions models used to compute the EM field are considered. The RF magnetic field is weakly influenced by the plasma while the electric field components are strongly disturbed due to space-charge effects. In the plasma the transversal electric field is enhanced and the kz spectrum is narrower than in vacuum. The calculation of the resonant isotope heating is made by the Runge-Kutta method. The influence of ion-ion collisions, inhomogeneity of the static magnetic field B0, and the RF transversal magnetic field component on the ion acceleration is examined. These results are successfully compared with experiments of a minor isotope 44Ca heating measurements, made with an energy analyzer.

We present the general real- and redshift-space clustering properties of galaxies as measured in the first data release of the VIPERS survey. VIPERS is a large redshift survey designed to probe in detail the distant Universe and its large-scale structure at 0.5 < z < 1.2. We describe in this analysis the global properties of the sample and discuss the survey completeness and associated corrections. This sample allows us to measure the galaxy clustering with an unprecedented accuracy at these redshifts. From the redshift-space distortions observed in the galaxy clustering pattern we provide a first measurement of the growth rate of structure at z = 0.8: fσ8 = 0.47 ± 0.08. This is completely consistent with the predictions of standard cosmological models based on Einstein gravity, although this measurement alone does not discriminate between different gravity models. Based on observations collected at the European Southern Observatory, Cerro Paranal, Chile, using the Very Large Telescope under programmes 182.A-0886 and partly 070.A-9007.

We present the first abundance analysis of the rapidly oscillating chemically peculiar star HD24712, and determine a T_eff,=7250K, log {g},=4.3, and xi_t ,=1kms(-1) . Microturbulence seems to be entirely simulated by a magnetic field with a polar field strength of 4.4kG and of dipolar structure, both of which are supported by our polarimetric observations. Rotation of HD24712 and a spotty surface distribution of the elements result in different mean abundances for different (magnetic) phases. Our results do not support the hypothesis of a monotonic correlation between the amplitude of abundance variations and the atomic number Z, and we present arguments in favour of one of the rotation periods (Prot=12\\fd 4610) discussed in the literature. Rare earth elements are the most overabundant elements relative to the sun, and they have the largest abundance amplitude during a rotation cycle; only Mg has a larger amplitude. For HD24712 we find a clear overabundance of Co while most of the other iron peak elements are underabundant. A comparison of the abundance pattern with the other three roAp stars analyzed so far by us concludes the paper. A systematic difference between surface gravities obtained from spectroscopy and from both asteroseismology and evolutionary tracks is found for the roAp stars HD 24712, alpha Cir, and gamma Equ.

A random two-dimensional large scale nano-network of silver nanowires (Ag-NWs) is fabricated by MeV hydrogen (H+) ion beam irradiation. Ag-NWs are irradiated under H+ ion beam at different ion fluences at room temperature. The Ag-NW network is fabricated by H+ ion beam-induced welding of Ag-NWs at intersecting positions. H+ ion beam induced welding is confirmed by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Moreover, the structure of Ag NWs remains stable under H+ ion beam, and networks are optically transparent. Morphology also remains stable under H+ ion beam irradiation. No slicings or cuttings of Ag-NWs are observed under MeV H+ ion beam irradiation. The results exhibit that the formation of Ag-NW network proceeds through three steps: ion beam induced thermal spikes lead to the local heating of Ag-NWs, the formation of simple junctions on small scale, and the formation of a large scale network. This observation is useful for using Ag-NWs based devices in upper space where protons are abandoned in an energy range from MeV to GeV. This high-quality Ag-NW network can also be used as a transparent electrode for optoelectronics devices.

Science cafés (a.k.a. café scientifiques) engage unconventional adult audiences and help researchers hone their communication skills in a relaxed and fun setting. Typically held in restaurants and pubs, science cafés provide a comfortable place for the public to speak with a scientist. National and local evaluations of the café format indicate that café are an effective way to engage adult audiences (especially non-scientists). Continued media coverage also demonstrates that something about them captures the public's imagination. This paper is based on an interactive oral presentation about organizing, presenting, and partnering with science café to bring IYA themes (and other current research) directly to new audiences. Real world examples from experienced café organizers and presenters provide an overview of what a science café is, how to start one, and how to use the format to draw attention to astronomy topics. The discussion includes suggestions for tapping into the existing national and international community of cafés (there are more than 60 in the U.S. alone), and information about free outreach resources. Break-out exercises in the original oral presentation were designed to help prepare participants to: find a suitable venue, advertise, work with café speakers, and foster the inclusive conversation that is the hallmark of a science café. Participants also learned about the impacts that can be expected from a science café, including benefits to audiences, café presenters, and hosting organizations. The overall goal of the original oral presentation was to stimulate a discussion about strategies for facilitating face-to-face communication between scientists and lay audiences.

We present detections of the near-infrared thermal emission of three hot Jupiters and one brown dwarf using the Wide-field Infrared Camera (WIRCam) on the Canada-France-Hawaii Telescope (CFHT). These include Ks-band secondary eclipse detections of the hot Jupiters WASP-3b and Qatar-1b and the brown dwarf KELT-1b. We also report Y-band, K CONT-band, and two new and one reanalyzed Ks-band detections of the thermal emission of the hot Jupiter WASP-12b. We present a new reduction pipeline for CFHT/WIRCam data, which is optimized for high precision photometry. We also describe novel techniques for constraining systematic errors in ground-based near-infrared photometry, so as to return reliable secondary eclipse depths and uncertainties. We discuss the noise properties of our ground-based photometry for wavelengths spanning the near-infrared (the YJHK bands), for faint and bright stars, and for the same object on several occasions. For the hot Jupiters WASP-3b and WASP-12b we demonstrate the repeatability of our eclipse depth measurements in the Ks band; we therefore place stringent limits on the systematics of ground-based, near-infrared photometry, and also rule out violent weather changes in the deep, high pressure atmospheres of these two hot Jupiters at the epochs of our observations.

2007-05-01

Context: Nearby galaxies, spirals as well as irregulars, have been found to be much larger than previously believed. The structure of the huge spheroid surrounding dwarf galaxies could give clues to their past gravitational history. Thanks to wide field imagers, nearby galaxies with diameter of dozens of arcmin can be effectively surveyed. Aims: We obtain, from the CFHT archives, a series of i' and g' MegaCam images of IC 1613 in order to determine the stellar surface density of the field and determine the shape of its spheroid. Methods: From the colour magnitude diagram we select some 36 000 stars, in the first three magnitudes of the red giant branch. The spatial distribution of these stars is used to establish the structure of the spheroid. Results: The position angle of the major axis of the stellar spheroid is found to be ≈90°, some 30° from the major axis of the HI cloud surrounding IC 1613. The surface density profile of the spheroid is not exponential over all the length of the major axis. A King profile, with a core radius of 4.5' and a tidal radius of 24' fits the data. The tidal truncation of the spheroid suggests that IC 1613 is indeed a satellite of M 31.

The nutrient profile concept implies that it is possible to discriminate between foods according to their contribution to a healthy diet on the basis of their nutrient contents only. The objective was to test the compatibility between nutrient profiling and nutrient-based recommendations by using diet modeling with linear programming. Food consumption data from the French "Individuelle et Nationale sur les Consommations Alimentaires" dietary survey and its associated food-composition database were used as input data. Each food was allocated to 1 of 4 classes, according to the SAIN,LIM system -- a nutrient profiling system based on 2 independent scores, including a total of 8 basic plus 4 optional nutrients. The possibility to model diets fulfilling a set of 40 nutrient recommendations (healthy models) was tested by using foods from a given nutrient profile class only or from a combination of classes. The possibility to fulfill a set of nutrient constraints in contradiction with the recommendations (unhealthy models) was also tested. For each model, the feasible energy range was assessed by minimizing and maximizing total energy content. With foods from the most favorable nutrient profile class, healthy diets could be modeled, but it was impossible to design unhealthy diets within a realistic range of energy intake with these foods. With foods from the least favorable class, unhealthy, but not healthy, diets could be designed. Both healthy and unhealthy diets could be designed with foods from intermediate classes. On the basis of a few key nutrients, it is possible to predict the ability of a given food to facilitate -- or to impair -- the fulfillment of a large number of nutrient recommendations.

Health care professionals often forget that there are risks associated with infusion therapy even if it is a common care. In order to assess this practice and to draw potential improvement actions, an audit of local gravity-flow intravenous infusion practices was conducted. The audit, based on a grid including 66 items from the medical prescription to the end of the infusion therapy administration, was conducted in the 6 units which use the most gravity-flow intravenous infusion devices. A multidisciplinary working group was created to decide and organize priority corrective measures in order to improve infusion practices and quality of healthcare. The audit enabled to observe 90hours of nurse's practices (96 infusions) and highlighted heterogeneity in infusion, in some cases inappropriate infusion practices and misuse of infusion devices. We found 4 main issues: labelling infusion therapy, training of health care professionals on good practices, support the purchase of infusion pumps and standardize perfusion line. An interactive educational program for nurses (workshops) was organized to enhance the respect of good practices: infusion identification at any time, respect of hygiene rules, flow rate regulation by counting drops, appropriate use of pumps and flow rate regulators. The audit drew up work priorities. The workshops made easier exchanges between professionals and had a warm welcome that's why it is essential to carry on such training. This collaborative approach between pharmacists, nurses, hygienists and biomedical technicians contribute to drug management improvement and promote optimal patient care.

[Death certificate data in France: Production process and main types of analyses].

PubMed

Rey, G

2016-10-01

Mortality data, by the unambiguity of their definition and understanding by all stakeholders, and completeness of registration, are a cornerstone of public health statistics in France and in most industrialized countries. This article describes the data production process, and the main types of possible analyses. Data production is composed of different stages: death certification by a medical doctor on paper or electronic (using a web application) format, data transmission to Inserm, capture and coding of information. The encoding of the information follows the WHO recommendations of the International Classification of Diseases ([ICD], 10th revision used since 2000). It is carried out using an automatic coding software, called Iris, developed in an international consortium. The coding aims, first, at assigning an ICD code to all nosologic entities encountered on the certificate, and then at selecting the underlying cause of death. The latter is the main information used for statistical analyses. Three main types of analysis emerge in the literature: the exploitation of data on the death certificate only, ecological analyses (studies of associations between variables measured across groups) and analysis from data individually linked to other databases. Many public health issues can be addressed with these various analyses. Several developments in the production process are being implemented: the deployment of electronic certification, increased automation of the death certificate information processing and durable and complete record linkage with health insurance and hospitalisation data. They could soon be deeply expanding the scope of possible uses of causes of death data. Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS.

In case of a bite by a rabies infected animal, the World Health Organisation recommends a prophylactic treatment including the administration of Human Rabies Immunoglobulins (HRIGs) or highly purified F(ab')2 fragments produced from Equine Rabies Immunoglobulin (F(ab')2 - ERIGs). According to international regulation, quality control of F(ab')2 - ERIGs lots requires potency testing by the in vivo Mouse Neutralisation Test (MNT) prior marketing. However, the strategy of the 3Rs (Reduce, Refine, Replace) for animal testing required by the European Directive encourages the replacement of the in vivo potency test by an in vitro assay. In this context, a competitive ELISA method (c-ELISA) has been developed by the Agence Nationale de Sécurité du Médicament et des Produits de Santé where F(ab')2 - ERIGs are in competition with a monoclonal antibody recognizing the trimeric native form of the rabies glycoprotein. After a full validation study, the c-ELISA has been applied to commercial batches of F(ab')2 - ERIGs. A correlation study with the MNT demonstrated a similarity between the two methods (r=0.751). Moreover, the c-ELISA method which does not need any species specific reagent has been applied to HRIGs potency testing as an alternative method to Rapid Fluorescent Focus Inhibition Test (RFFIT), thus avoiding the handling of live rabies virus in BSL3 containment. In conclusion, the c-ELISA has shown its potential to replace MNT and possibly RFFIT for the quantification of rabies immunoglobulin. After optimisation it may be used for the quantification of rabies immunoglobulin in any animal species, notably for rabies immunogenicity assay in mice. Copyright © 2016 Elsevier Ltd.

This study aimed to identify and compare physician-pharmacist perceptions concerning drug teaching to physicians by pharmacists in Swiss hospital settings. Questionnaires were emailed to all French-speaking physicians (survey A) and pharmacists (survey B) working in Swiss hospitals where medical directors/chief-pharmacists had approved the study. Questions were developed based on previous physician interviews. Most questions used four Likert-type response alternatives. A Mann-Whitney U test was used to compare answers to survey A and B. Fourteen out of 18 medical directors and 16/16 chief-pharmacists gave permission for the study. In total, 244 (11%) physicians answered survey A, and 115 (74%) pharmacists answered survey B. Nearly all participants agreed that pharmacists should take part in both medical student and physician postgraduate training. Most physicians answered wanting additional training and pharmacists are unaware of this need. Only two thirds of physicians reported having acquired knowledge about drugs thanks to pharmacists; document diffusion and direct answers to their questions having contributed the most to their training. Participants agreed that physician training by pharmacists needs a clearer delineation regarding the type of training, its aim, its targeted public, when and what pharmaceutical benefits are used. Physicians' priority-training topics are high-risk drugs, novelties and areas in which they consider their basic training was insufficient. Methods preferred for training are: case studies; exercises with individual corrections; and group work. Improved resources and planning are needed to meet physicians' expectations. Training is often carried out implicitly, through activities with various other aims, and needs to be better defined and formalized collaboratively. Copyright © 2018 Académie Nationale de Pharmacie.

Chitosan, the linear polymer, is produced by alkali deacetylation of chitin (CHI). Recently chitin and chitosan were attracted marked interest due to their biocompatibility, biodegradability and non-toxicity. In this study, chitin was extracted from shrimp shell (Parapenaeus longirostris) and chitosan was deacetylated by classical and ultrasound-assisted method. The identification of functional groups and the determination of degree of deacetylation of chitin (CHI), classical deacetylated chitosan (CDC) and ultrasound-assisted deacetylated chitosan (UDC) were carried through Fourier Transform-Infrared Spectroscopy. Their antimicrobial and antioxidant activity were also investigated. The degree of deacetylation of CHI, CDC and UDC is 33.64%, 73.68% and 83.55%, respectively. Results showed that CHI, CDC and UDC exhibited a good antimicrobial activity against (S. aureus, E. coli, P. aeruginosa, K. pneumonia) and (C. albicans and C. parapsilosis). The scavenging ability of CHI, CDC and UDC on 1,1-diphenyl-2-picrylhydrazyl radicals is ranging from 4.71% to 21.25%, 11.45% to 32.78% and 18.27% to 44.17%, respectively, at the concentrations of 0.25 to 1mg/mL. The inhibition of lipid peroxidation with thiobarbituric acid-reacting substances is ranging from 11.7% to 51.63%, 17.24% to 63.52% and 29.31% to 77.39%, respectively, at varying concentrations of 0.25 to 1mg/mL. The effectiveness of CHI, CDC and UDC is correlated with their degree of deacetylation. The results indicate the possibility of exploiting chitin and chitosan as antimicrobial agent.

Parvovirus B19 causes erythema infectiosum in children, transient aplastic anemia in patients with hemoglobinopathies, pur red cell aplasia in immunocompromised persons and hydrops fetalis in pregnancy. The spectrum of clinical and biological manifestations in immunocompetent adult continues to grow up. We report on a case series of 26 patients with primary parvovirus B19 infection in immunocompetent adults. This is a retrospective study over the period 2000 to 2010 in two departments of internal medecine. The diagnostic was clinical, serological or molecular. There was a female predominance (sex-ratio 3.33/1). Median patient age at diagnostic was 38.8 years (range: 18-68). The predominant symptoms were fever (65%), peripheral and symmetrical polyarthralgia (62%) and skin rash (58%). Two patients had neurological manifestations (sixth cranial nerve palsy, distal paresthesia) and one patient had myocarditis. Abnormal laboratory values included increased acute phase reactants (73%), thrombocytopenia (43%), lymphopenia (38%) and elevated liver enzymes (37%). Antinuclear (19%), anti-DNA (28%) and anti-phospholipids antibodies (14%), and hypocomplementemia (32%) were observed. False reaction with anti-CMV and anti-EBV IgM positivity was documented in 27% of cases. Two patients had persistent parvovirus B19 infection. The diversity of the clinical manifestations of parvovirus B19 infection may be misleading for the clinician. However, the diagnosis should be suspected in immunocompetent adults to limit the risk of transmission to the patients who could develop a severe infection such as pregnant women or immunocompromised patients.

The aim of the present study was to isolate, identify and characterise novel strains of lactic acid bacteria and bifidobacteria with probiotic properties from the faeces of exclusively breast-fed infants. Of the 4680 isolated colonies, 758 exhibited resistance to low pH and tolerance to high concentrations of bile salts; of these, only forty-two exhibited a strong ability to adhere to enterocytes in vitro. The identities of the isolates were confirmed by 16S ribosomal RNA (rRNA) sequencing, which permitted the grouping of the forty-two bacteria into three different strains that showed more than 99 % sequence identity with Lactobacillus paracasei, Lactobacillus rhamnosus and Bifidobacterium breve, respectively. The strain identification was confirmed by sequencing the 16S-23S rRNA intergenic spacer regions. Strains were assayed for enzymatic activity and carbohydrate utilisation, and they were deposited in the Collection Nationale de Cultures de Microorganismes (CNCM) of the Institute Pasteur and named L. paracasei CNCM I-4034, B. breve CNCM I-4035 and L. rhamnosus CNCM I-4036. The strains were susceptible to antibiotics and did not produce undesirable metabolites, and their safety was assessed by acute ingestion in immunocompetent and immunosuppressed BALB/c mouse models. The three novel strains inhibited in vitro the meningitis aetiological agent Listeria monocytogenes and human rotavirus infections. B. breve CNCM I-4035 led to a higher IgA concentration in faeces and plasma of mice. Overall, these results suggest that L. paracasei CNCM I-4034, B. breve CNCM I-4035 and L. rhamnosus CNCM I-4036 should be considered as probiotic strains, and their human health benefits should be further evaluated.

Few studies have focused on the influence of retirement on dietary behaviors. Our study aimed at assessing the associations between transition to retirement and changes in dietary intake in French adults, particularly according to spousal retirement and baseline income. This prospective study included 577 French participants from the NutriNet-Santé cohort who retired over a 5-year follow-up (2009-2014 or 2010-2015). At baseline and every year, dietary intakes were assessed using 24 h records. Repeated measures of dietary intake were analysed using mixed models adjusted for energy with random effects of time and period (before and after retirement) to assess changes following retirement for each gender. After retirement, intakes of saturated fatty acids and sodium increased in both genders. Women showed specific changes after retirement: decrease in the score of adherence to recommendations and in intakes of fruits, proteins, vitamins; increase in intakes of fatty sweet products. In men with the lowest income at baseline, specific changes in intake were associated with retirement such as decrease in intake of dairy products and increase in intake of lipids. Transition to retirement was associated with unhealthier dietary intakes. These results may help defining interventions during this vulnerable life-period. This study was conducted according to guidelines laid down in the Declaration of Helsinki and all procedures were approved by the Institutional Review Board of the French Institute for Health and Medical Research (IRB Inserm No. 0000388FWA00005831) and the French Data Protection Authority (Commission Nationale Informatique et Libertés No. 908450 and No. 909216).

Our objectives were (i) to assess the current prevalence of childhood overweight (including obesity) (OWOB) in France and its relationship with comprehensive socioeconomic status (SES) indicators and (ii) to examine trends in OWOB prevalence and changes in energy intake (EI) and sedentary behavior (SED) based on the previous INCA 1 (Individuelle Nationale des Consommations Alimentaires) data (1998-1999). A representative sample of children aged 3-14 (n = 1,030) was taken from the 2006-2007 cross-sectional INCA 2 food consumption survey. Weight and height were measured. The prevalence of OWOB was estimated according to the IOTF (International Obesity Task Force) definition. Average daily EI was evaluated using a 7-day food record. SED (screen time) and SES were reported by answering questionnaires. SES indicators included the occupation and level of education of the head of the household (HH), and variables describing household wealth. Composite indices of SES were computed by correspondence analysis, and relationships with OWOB were explored by logistic regression analysis. In total, 14.5% (95% CI: 12.1-17.0) of the children were OWOB. All SES indicators were inversely correlated to OWOB. Average EI was equal to 1,739 kcal/day. Daily, children spent 113.5 min watching television, and 38.5 min playing video games or using a computer. Compared to the INCA 1 study, OWOB prevalence was not significantly different, EI was lower, and SED was higher. These trends were the same across all occupational categories of heads of household. Although overall rates of childhood OWOB are currently stabilizing, no change was observed in the strong inverse socioeconomic gradient of OWOB between the two studies.

To describe factors associated with a better rank, and to assess the impact of training conferences on medical student's performance for the French National Ranking Examination (FNRE) in Lorraine University, France in 2012. Between October 2011 and May 2012, assistant professors of the faculty of medicine of Nancy, France, organized a cycle of 15 conferences combining clinical cases theoretical training and student peer assessment. Data were recorded with a self-administered questionnaire in January 2012 to collect potential confounders. Among 287 students enrolled in the last year of medical school in 2011-2012 in Lorraine University, 195 (67.9%) of them registered to the cycle of conferences. Among the potential prognostic factors assessed, not repeating the first year of medical curriculum (P=0.013), the number of courses validated at the first session during the second part of the medical curriculum (P=0.002), absence of difficulties experienced in the fifth and sixth year (P=0.032) and a desired ranking among the best (P=0.011) were independently associated with a better rank at the FNRE. Regular participation in conferences was significantly and independently associated with a higher ranking (mean gain for the participation in 13 or more conferences: 873; mean gain by conference: 63). Regular participation in conferences provided by assistant professors and based on clinical cases theoretical training and student peer assessment was significantly associated with a higher ranking to the FNRE in Lorraine University in 2012.

BACKGROUND Deep dermatophytosis is a severe and sometimes life-threatening fungal infection caused by dermatophytes. It is characterized by extensive dermal and subcutaneous tissue invasion and by frequent dissemination to the lymph nodes and, occasionally, the central nervous system. The condition is different from common superficial dermatophyte infection and has been reported in patients with no known immunodeficiency. Patients are mostly from North African, consanguineous, multiplex families, which strongly suggests a mendelian genetic cause. METHODS We studied the clinical features of deep dermatophytosis in 17 patients with no known immunodeficiency from eight unrelated Tunisian, Algerian, and Moroccan families. Because CARD9 (caspase recruitment domain–containing protein 9) deficiency has been reported in an Iranian family with invasive fungal infections, we also sequenced CARD9 in the patients. RESULTS Four patients died, at 28, 29, 37, and 39 years of age, with clinically active deep dermatophytosis. No other severe infections, fungal or otherwise, were reported in the surviving patients, who ranged in age from 37 to 75 years. The 15 Algerian and Tunisian patients, from seven unrelated families, had a homozygous Q289X CARD9 allele, due to a founder effect. The 2 Moroccan siblings were homozygous for the R101C CARD9 allele. Both alleles are rare deleterious variants. The familial segregation of these alleles was consistent with autosomal recessive inheritance and complete clinical penetrance. CONCLUSIONS All the patients with deep dermatophytosis had autosomal recessive CARD9 deficiency. Deep dermatophytosis appears to be an important clinical manifestation of CARD9 deficiency.

[Day hospital in internal medicine: A chance for ambulatory care].

Grasland, A; Mortier, E

Internal medicine is an in-hospital speciality. Along with its expertise in rare diseases, it shares with general medicine the global care of patients but its place in the ambulatory shift has yet to be defined. The objective of our work was to evaluate the benefits of an internal medicine day-hospital devoted to general medicine. Named "Centre Vi'TAL" to underline the link between the city and the hospital, this novel activity was implemented in order to respond quickly to general practitioners having difficulties to synthesize their complex patients or facing diagnostic or therapeutic problems. Using preferentially email for communication, the general practitioners can contact an internist who is committed to respond on the same day and take over the patient within 7 days if day-hospital is appropriate for his condition. The other patients are directed either to the emergency department, consultation or full hospitalization. In 14 months, the center has received 213 (144 women, 69 men) patients, mean age 53.6, addressed by 88 general practitioners for 282 day-hospital sessions. Requests included problem diagnoses (n=105), synthesis reviews for complex patients (n=65), and treatment (n=43). In the ambulatory shift advocated by the authorities, this experience shows that internal medicine should engage in the recognition of day-hospital as a place for diagnosis and synthesis reviews connected with the city while leaving the general practitioners coordinator of their patient care. This activity of synthesis in day-hospital is useful for the patients and efficient for our healthcare system. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

The French National Programme on Nutrition and Health (Programme national nutrition santé (PNNS)), the aim of which is to reduce nutrition-related chronic diseases, necessitates monitoring of nutritional characteristics. Our objective was to describe dietary intake, physical activity and nutritional status in a national sample of adults, especially according to current French recommendations. The study is based on a cross-sectional population-based survey using a multistage sampling design (Etude nationale nutrition santé (ENNS)). Between February 2006 and March 2007, 3115 18-74-year-old adults were included (participation rate 59.7 %). Energy, macronutrient and food consumption were estimated through three randomly distributed 24 h recalls, and compared to PNNS recommendations; physical activity was described using International Physical Activity Questionnaire guidelines; anthropometry, blood pressure and biochemical measurements were assessed according to national and international references. When compared to current recommendations, intake of carbohydrates (>50 % energy intake without alcohol: 26.4 %), SFA ( < 35 % total lipids: 18.5 %) and total fibre (>25 g/d: 13.7 %) was frequently unsatisfactory. While overall consumption of 'meat, seafood and eggs' was satisfactory, that of fruits and vegetables ( > or = 400 g/d: 43.8 %) and seafood (two or more servings per week: 29.9 %) was frequently too low. The physical activity level was satisfactory at 63.2 %. Overweight was observed in 49.3 % of adults, while 30.9 % were hypertensive and 44.1 % had dyslipidaemia. Vitamin and iron-poor status was found to affect less than 10 % of the population. Based on the ENNS survey, overall nutrition remains a problem in France. Comparison of these data with those of other countries could contribute to a better understanding of variations in nutrition-related diseases.

Chronic Lyme disease is a subject of scientific and social controversy in both Europe and the United States. The aim of our study was to analyze the pathway to diagnosis of patients believing they were affected by the disease, and to describe their real-life experience. A qualitative study was performed with 13 patients declaring themselves to be affected by chronic Lyme disease. Interviews were analyzed by 2 general medical practice interns, supervised by a general practitioner with a diploma in socio-anthropology and an infectious diseases specialist. Internet and other media played a major role in informing the patients or their doctor about the existence and the characteristics of chronic Lyme disease. The diagnosis was confirmed by features considered objective (chronic infection by Borrelia, tick bite, positive serology, beneficial or worsening effects of antibiotics). The long medical diagnosis and treatment process of those interviewed was marked by a conflicted relationship with the medical profession, caused by a feeling of non-recognition and abandonment. They reported their experience as being very painful, both because of the physical pain and also the psychological consequences of their condition. Improving the diagnosis and therapeutic management of patients believing themselves to be affected by chronic Lyme disease appears highly necessary both to limit their search for diagnosis and their experience of pain. It could be based on existing guidelines concerning medically unexplained symptoms to which the chronic Lyme disease issue appears quite similar on several points.

Isocyanides are less stable isomers of nitriles and some of them have already been observed in the interstellar medium (HNC, CH_3NC, HCCNC). But still there exists a lack of experimental spectroscopic data on simple isocyanic molecules that can represent potential astrophysical interest. In this view we have performed high resolution studies of rotational spectra of allyl isocyanide (CH_2=CH--CH_2--NC) and diisocyanomethane (CN--CH_2--NC). The rotational spectra of allyl isocyanide have been measured in the frequency range 6 -- 18 GHz by means of FTMW spectrometer in Bilbao and in the frequency range 150 -- 945 GHz by means of classic absorption spectroscopy in Lille. Two stable confomers of allyl isocyanide have been observed in both series of measurements. In addition, all 13C-monosubstituted isotopologues and 15N isotopologues were detected in natural abundance. Due to much lower kinetic stability the rotational spectrum of diisocyanomethane has been measured only in absorption using the Lille spectrometer. The spectral assignments have been supported by high-level quantum chemical calculations. For both molecules accurate sets of rotational and centrifugal distortion constants (up to the octics) have been produced. As a result, reliable predictions of transitions frequencies suitable for astrophysical detection have been obtained for both molecules. Finally, the effective and substitution structures were determined for the two conformers of allyl isocyanide, comparing the result with ab initio data.

Hailstorms are meteorological phenomena of great interest to the scientific community, owing to their socioeconomic impact, which is mainly on agricultural production. With its global coverage and high spatial and temporal resolution, satellite remote sensing can contribute to monitoring of such events through the development of appropriate techniques. This paper presents an extensive validation in the south of France of a hail detection tool (HDT) developed for the Middle Ebro Valley (MEV). The HDT is based on consecutive application of two filters, a convection mask (CM) and hail mask (HM), using spectral channels of the Meteosat Second Generation (MSG) satellite. The south of France is an ideal area for studying hailstorms, because there is a robust database of hail falls recorded by an extensive network of hailpads managed by the Association Nationale d'Etude et de Lutte contre les Fleáux Atmosphériques (ANELFA). The results show noticeably poorer performance of the HDT in France relative to that in the MEV, with probability of detection (POD) 60.4% and false alarm rate (FAR) 26.6%. For this reason, a new tool to suit the characteristics of hailstorms in France has been developed. The France Hail Detection Tool (FHDT) was developed using logistic regression from channels of the Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensor of the MSG. The FHDT was validated, resulting in POD 69.3% and FAR 15.4%, thus improving hail detection in the study area as compared with the previous tool. The new tool was tested in a case study with satisfactory results, supporting its future practical application.

The recently introduced oral direct anticoagulants (ODAs), presumably safer, and with comparable efficacy to the vitamin K antagonists (VKAs), may reshape the world of anticoagulation medicine. This study aimed to assess the prescription appropriateness of ODAs and VKAs at discharge from hospital. We performed a one year retrospective study between August 2012 and July 2013 in the department of internal medicine of a regional hospital (HVs Sion) using Electronic Medical Records. All patients receiving an ODA were included and matched to a patient treated with a VKA. The appropriateness of prescription at discharge was defined by an adequate indication and dosing, the absence of contraindication, a minimal risk of drug-drug interactions and no major bleeding or venous thromboembolism during the hospitalization. The bleeding risk was evaluated with the HAS-BLED score when the indication was atrial fibrillation (AF). Out of the 44patients included (22 with an ODA and 22 with a VKA), 38 received an appropriate prescription according to all criteria. Two patients had an inadequate dosing. A potential drug-drug interaction was detected in 3patients receiving a VKA and in 1patient receiving an ODA. No major contraindication was found, but a relative contraindication was discussed in 3cases. The majority of patients receiving an ODA for an AF had a minor bleeding risk. No significant difference was ascertained between the two groups regarding the appropriateness of prescription. Our results suggest that ODAs were cautiously used in our setting.

In June 2009, the national French authority for Health reported many off-label uses of proton pump inhibitors (PPI). Our objective was to analyse the justification and modalities of PPI prescriptions in patients before their admission in a department of internal medicine. Data were prospectively collected during 5months. At admission, all prescriptions of PPI by general practitioners (GP) were recorded. The accordance of the prescriptions with the marketing authorization indications and the French guidelines in terms of duration of treatment or dosage was analyzed. These informations were obtained from computerized medical records and, if necessary, by contacting GPs. We collected 173 prescriptions. Fifty-six (32%) were in accordance with marketing authorization indications and, among them, 15 prescriptions (9% of all) respected the French guidelines about dosage and duration of treatment. One hundred and six prescriptions (61%) were not adequate and among them an off-label use was notified in 91 (53% of all); among them 33% for simple dyspeptic disorders, 23% for the prevention of NSAID-induced lesions in patients without risk factors, and finally 17% for the prevention of stress ulcer. Fifty-two prescriptions (30%) were unclassified due to incomplete data. Our study showed that a vast majority of the prescriptions for PPIs are not in accordance with French guidelines. Preventive actions against abusive prescriptions, withdrawal strategies or replacement of already prescribed PPIs should be implemented to reduce the risk of side effects and the economic impact of long term use of PPIs.

An innovative simple, fast, precise and accurate ultra-high performance liquid chromatography (UPLC) method was developed for the determination of diclofenac (Dic) along with its impurities including the new dimer impurity in various pharmaceutical dosage forms. An Acquity HSS T3 (C18, 100×2.1mm, 1.8μm) column in gradient mode was used with mobile phase comprising of phosphoric acid, which has a pH value of 2.3 and methanol. The flow rate and the injection volume were set at 0.35ml·min(-1) and 1μl, respectively, and the UV detection was carried out at 254nm by using photodiode array detector. Dic was subjected to stress conditions from acid, base, hydrolytic, thermal, oxidative and photolytic degradation. The new developed method was successfully validated in accordance to the International Conference on Harmonization (ICH) guidelines with respect to specificity, limit of detection, limit of quantitation, precision, linearity, accuracy and robustness. The degradation products were well resolved from main peak and its seven impurities, proving the specificity power of the method. The method showed good linearity with consistent recoveries for Dic content and its impurities. The relative percentage of standard deviation obtained for the repeatability and intermediate precision experiments was less than 3% and LOQ was less than 0.5μg·ml(-1) for all compounds. The new proposed method was found to be accurate, precise, specific, linear and robust. In addition, the method was successfully applied for the assay determination of Dic and its impurities in the several pharmaceutical dosage forms. Copyright © 2016 Académie Nationale de Pharmacie.

Sedation in palliative care meets a precise definition and corresponds to a medical practice. We assessed the comprehension of this practice by the French population. In 2015, citizen expressed their views on the Claeys-Leonetti bill by means of a consultative forum made available on the Internet site of the National Assembly. The content of the messages filed, regarding the right to deep and continuous sedation until death was analyzed using the ALCESTE textual data analysis software, supplemented by a thematic analysis in order to identify the perception that Internet users had of this practice. Among the 1819 Internet users who participated in the forum, 67 expressed their views as Health professionals, 25 of whom were directly involved in palliative care, as well as 10 sick persons. Analysis with the ALCESTE software highlighted two classes of statements. The first dealing with deep and continuous sedation, reflecting the specificity of the discourse of the Internet users. The second one consisted of textual units in which the modal verbs were dominant and overrepresented, thus providing information on the participants' perceptions. The thematic analysis highlighted four themes: death, intent, treatment and fear. Deep and continuous sedation is perceived as a euthanasic practice or raises fear of such a drift. Provision of extended and accurate information to the population and health professionals is essential to ensure that this new model of sedation is integrated into the care of the terminally ill patients and their families.

Lead is a highly toxic contaminant with food being the major source of exposure for the general public. The second German food consumption survey (Nationale Verzehrsstudie II - NVS II) with about 20 000 participants (15 371 for dietary history interviews used for this study) allowed for an updated exposure assessment for the German population. Based on these comprehensive data, information on consumption of 545 individual food items by the German population was generated. Lead concentrations in food were compiled from the German food monitoring programme, European countries' authority programmes and the published literature, covering the years from 2000 to 2009, and were multiplied with consumption data to obtain estimates of lead intake from food. Average lead concentrations per main food group were highest for meat (including offal), followed by fish (including seafood), vegetables and cereals. Due to high consumption, beverages contributed most to the intake of the general public, followed by main groups vegetables, fruits & nuts and cereals. Lead intake from food was estimated to be 0.53 and 0.72 µg kg(-1) bw and day for average and high-end consumers, respectively. This is close to (average consumers) respectively above (high-end consumers) a reference value derived from a recent health risk evaluation performed by EFSA, using the benchmark approach. Uncertainties in these estimates pertain to the influence of values below the limit of quantification and some foods not considered due to lacking occurrence data. In conclusion, the estimated lead intake of the German population from food is still close to health-based reference values. Further efforts to reduce lead intake are required.

Introduction Stroke is a leading cause of adult disability and death worldwide. The neurological impairments associated with stroke prevent patients from performing basic daily activities and have enormous impact on families and caregivers. Practical and accurate tools to assist in predicting outcome after stroke at patient level can provide significant aid for patient management. Furthermore, prediction models of this kind can be useful for clinical research, health economics, policymaking and clinical decision support. Methods 2869 patients with first-ever stroke from South London Stroke Register (SLSR) (1995–2004) will be included in the development cohort. We will use information captured after baseline to construct multilevel models and a Cox proportional hazard model to predict cognitive impairment, functional outcome and mortality up to 5 years after stroke. Repeated random subsampling validation (Monte Carlo cross-validation) will be evaluated in model development. Data from participants recruited to the stroke register (2005–2014) will be used for temporal validation of the models. Data from participants recruited to the Dijon Stroke Register (1985–2015) will be used for external validation. Discrimination, calibration and clinical utility of the models will be presented. Ethics Patients, or for patients who cannot consent their relatives, gave written informed consent to participate in stroke-related studies within the SLSR. The SLSR design was approved by the ethics committees of Guy’s and St Thomas’ NHS Foundation Trust, Kings College Hospital, Queens Square and Westminster Hospitals (London). The Dijon Stroke Registry was approved by the Comité National des Registres and the InVS and has authorisation of the Commission Nationale de l’Informatique et des Libertés. PMID:28821511

Lipids are an important source of energy for young children and play a major role in the development and functioning of nervous tissue. Essential fatty acids and their long-chain derivatives also fulfill multiple metabolic functions and play a role in the regulation of numerous genes. The Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO), and the French Agency for Food, Environmental and Occupational Health & Safety (Agence nationale de sécurité sanitaire de l'alimentation, de l'environnement et du travail [ANSES]) have recently recommended a minimum daily intake in preformed long-chain polyunsaturated fatty acids (LC-PUFAs): arachidonic acid (ARA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Mother's milk remains the only reference, but the large variability in its DHA content does not guarantee that breastfed children receive an optimal DHA intake if the mother's intake is insufficient. For children fed with infant formulas, ARA and DHA intake is often below the recommended intake because only one-third of infant formulas available on the market in France are enriched in LC-PUFAs. For all children, linoleic acid (LA) intake is on average higher than the minimal recommended values. The consequences of these differences between intake and recommended values are uncertain. A cautious attitude is to come close to the current recommendations and to advise sufficient consumption of DHA in breastfeeding women. For bottle-fed children, infant formulas enriched in LC-PUFAs and with moderate levels of LA should be preferred. LC-PUFA-rich fish should be consumed during breastfeeding, and adapted vegetable oils when complementary foods are introduced. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

The aim of this study was to collect information to design a patient education program (PEP) for patients with systemic lupus erythematosus (SLE), based as much as possible on their expectations. Three different approaches were used for addressing patients' needs: 1) A questionnaire on their expectations in terms of a PEP was sent to the members of SLE associations and offered to patients at the French reference center for SLE, 2) A patients' focus group was conducted, and 3) After the teaching sessions, satisfaction questionnaires were also evaluated. The patients who answered the expectation questionnaire (n=422, women/men sex-ratio: 12.6) indicated a major interest in the PEP (70.4%). Their expectations were broad, and covered the topics of pregnancy (90% of the women under the age of 40), the outcome of the disease (80.8%), the respective roles of the different treatments (70.4%), and also the management of everyday symptoms: fatigue and pain (66.4%). The focus group (eight people) highlighted the need for improving how the diagnosis of the disease was delivered, and also revealed the loneliness and the guilty feeling experienced by some patients toward their relatives. Satisfaction questionnaires confirmed these expectations for the PEP, and even extended them to new topics: the mechanisms behind SLE, travel and leisure, and possible accommodations in the workplace. The direct consultation of patients with SLE targeted by a specific PEP program allowed us to confirm and adapt the topics and the content of a program designed by medical staff.

and astronomy have a long common history. Indeed, we are reminded that a century ago, terrestrial and solar helium were identified with one another through spectral lines, while recent studies of nebulae and the interstellar medium provide nice examples of the continuing interplay between spectroscopy and astrophysical models. During the Amsterdam meeting, some astrophysicists deplored that the so-called "traditional term analysis" was disappearing. They should be reassured about the near future owing to three invited papers and a great number of posters on this type of work. We are grateful to the members of the Scientific Committee who helped us to set up the scientific programme and to all the referees who reviewed the manuscripts published in this volume. We thank the Observatoire de Paris-Meudon, the Centre National de la Recherche Scientifique and the Centre National d'Etudes Spatiales for financial support.

Comité D'Organisation Du Colloque Ime 2002, Le

2002-12-01

Le LMARC a été créé par Raymond Chaléat dans les locaux de l'École Nationale d'Horlogerie (a présent Lycée Technique Jules Haag).L'équipe de recherche était alors constituée de 2 enseignants-chercheurs (Raymond Chaléat et Gérard Lallement) et d'un technicien (Bernard Prêtre). Les travaux de recherche se situaient naturellement dans le domaine de la chronométrie et en particulier dans la mécanique non linéaire analytique inhérente à la montre en fonctionnement. En effet, Raymond Chaléat fut l'élève, puis le collaborateur du Professeur Jules Haag, mathématicien et mécanicien, lui-même élève de Poincarré.Le LMARC a étendu ses activités avec l'arrivée de Claude Oudet, puis de Claude Oytana à la rhéologie des matériaux solides qui est devenue plus tard l'Équipe Propriétés Mécaniques des Matériaux. En parallèle, G. Lallement a créé une équipe Vibrations devenue à ce jour Dynamique des Structures. À ce jour, le Laboratoire compte plus de 110 personnes dont 40 doctorants.Il a depuis diversifié ses activités avec 3 nouvelles équipes tournées vers la Modélisation et la Mise en Forme des Matériaux, les Micromachines et la Biomécanique et les Mécanismes. Il a su également prendre toute sa place au sein de l'Institut des Microtechniques de Franche-Comté en contribuant à plusieurs thèmes.Notre Laboratoire a été l'un des premiers laboratoires associé au CNRS (4ème) et a toujours été rattaché à l'Université de Franche-Comté (Présidence par C. Oytana de 1996 a 2001) par l'entremise de I'UFR Sciences et Techniques. Il a toujours maintenu des liens forts avec I'ENSMM (École Nationale Supérieure de Mécanique et des Microtechniques) d'une part par ses enseignants-chercheurs et d'autre part deux de ses directeurs, Raymond Chaléat et actuellement Jean-Claude Gelin.En plus de ses relations constantes avec l'industrie régionale, le LMARC a développé des actions contractuelles avec de grands groupes tels que EDF

The Open Cluster NGC 2437 (Messier 46)

NASA Astrophysics Data System (ADS)

Davidge, T. J.

2013-02-01

The stellar content of the open cluster NGC 2437 (Messier 46) is investigated using moderately deep u∗, g‧, and r‧ MegaCam images. When compared with solar metallicity isochrones, the (g‧,u‧ - g‧) and (r‧,g‧ - r‧) CMDs are consistent with an age log(tyr) = 8.35 ± 0.15, a distance modulus μ0 = 11.05 ± 0.05, and a color excess E(B - V) = 0.115 ± 0.035. The r‧ luminosity function (LF) of main sequence stars in the magnitude range r‧ < 17 (i.e., masses ≳0.8 M⊙) has a shape that follows solar neighborhood star counts. However, at fainter magnitudes, the cluster LF is flat, in contrast with what would be expected from solar neighborhood counts. The clustering properties of stars in NGC 2437 are investigated by examining the two-point angular correlation functions of main sequence stars in different brightness ranges. Main sequence stars fainter than r‧ = 17 are less centrally concentrated than brighter stars and are found over a larger area of the sky, suggesting that there is a corona of faint main sequence stars around NGC 2437. Based on the flat LF and extended spatial distribution of faint stars, it is concluded that NGC 2437 is actively shedding stars with masses ≲0.8 M⊙. Based on observations obtained with MegaPrime/MegaCam, a joint project of CFHT and Commissariat à l'énergie atomique et aux énergies alternative (CEA)/Dapnia, at the Canada-France-Hawaii Telescope (CFHT), which is operated by the National Research Council (NRC) of Canada, the Institut National des Sciences de l’Univers of the Centre National de la Recherche Scientifique (CNRS) of France, and the University of Hawaii.

The purpose of this work was to study the impact of an audit and feedback on the quality of routine first-trimester nuchal transparency ultrasound images. Eighty-eight sonographers were each sent 2 different series of 30 consecutive nuchal translucency images at a mean interval of 3 months to a dedicated, protected server for remote double-blind independent analysis based on the new Collège Français d'Echographie Foetale/Centre National de la Recherche Scientifique image-scoring method (https://www.cfef.org/evaluation/ISMCFEFCNRS.pdf). The sonographers were classified as low (score below the median) or high (score above the median) scorers for each series. Before their second evaluation, 73 of the 88 sonographers received a feedback report on their first series of images, whereas the other 15 participants received no feedback. The baseline characteristics of the participants who did and did not receive feedback were comparable. Participants who received feedback increased their average score significantly, from a mean ± SD of 11.1 ± 1.3 to 13.4 ± 1.4 among low scorers (P < .00001) and from 15.1 ± 1.2 to 16.0 ± 1.4 among high scorers (P < .001), whereas no significant change was seen among participants who received no feedback (low scorers, 10.9 ± 1.5 to 12.1 ± 2.0; P = .11; high scorers, 14.7 ± 1.3 to 14.6 ± 1.3; P = .99). The proportion of satisfactory images increased by 48% among low scorers who received feedback. Formative assessment based on a moderately intensive audit and feedback is feasible and effective for improving the quality of routine first-trimester nuchal transparency ultrasound images.

This paper presents an investigation into the variability and predictability of the maximum height of the ionospheric F2 layer, hmF2 over the South African region. Data from three South African stations, namely Madimbo (22.4°S, 26.5°E, dip angle: -61.47°), Grahamstown (33.3°S, 26.5°E, dip angle: -64.08°) and Louisvale (28.5°S, 21.2°E, dip angle: -65.44°) were used in this study. The results indicate that hmF2 shows a larger variability around midnight than during the daytime for all seasons. Monthly median hmF2 values were used in all cases and were compared with predictions from the IRI-2007 model, using the URSI (Union Radio-Scientifique Internationale) coefficient option. The analysis covers the diurnal and seasonal hourly hmF2 values for the selected months and time sectors e.g. January, July, April and October for 2003 and 2005. The time ranges between (03h00-23h00 UT; LT = UT + 2h) representing the local sunrise, midday, sunset and midnight hours. The time covers sunrise, midday, sunrise, and midnight hours (03-06h00 UT, 07-11h00 UT, sunrise 16-18h00 UT and 22-23h00 UT; LT = UT + 2h). The dependence of the results on solar activity levels was also investigated. The IRI-2007 predictions follow fairly well the diurnal and seasonal variation patterns of the observed hmF2 values at all the stations. However, the IRI-2007 model overestimates and underestimates the hmF2 value during different months for all the solar activity periods.

Reliable atomic and molecular data are of great importance for different applications in astrophysics, atmospheric physics, fusion, environmental sciences, combustion chemistry, and in industrial applications from plasmas and lasers to lighting. Currently, very important resources of such data are highly fragmented, presented in different, nonstandardized ways, available through a variety of highly specialized and often poorly documented interfaces, so that the full exploitation of all their scientific worth is limited, hindering research in many topics like e.g. the characterization of extrasolar planets, understanding the chemistry of our local solar system and of the wider universe, the study of the terrestrial atmosphere and quantification of climate change; the development of the fusion rersearch, etc. The Virtual Atomic and Molecular Data Centre (http://www.vamdc.eu, VAMDC) is an European Union funded FP7 project aiming to build a secure, documented, flexible and interoperable e-science environment-based interface to existing atomic and molecular data. It will also provide a forum for training potential users and dissemination of expertise worldwide. Partners in the Consortium of the Project are: 1) Centre National de Recherche Scientifique - CNRS (Paris, Reims, Grenoble, Bordeaux, Dijon, Toulouse); 2) The Chancellor, Masters and Scholars of the University of Cambridge - CMSUC; 3) University College London - UCL; 4) Open University - OU; (Milton Keynes, England); 5) Universitaet Wien - UNIVIE; 6) Uppsala Universitet - UU; 7) Universitaet zu Koeln - KOLN; 8) Istituto Nazionale di Astrofisica - INAF (Catania, Cagliari); 9) Queen's University Belfast - QUB; 10) Astronomska Opservatorija - AOB (Belgrade, Serbia); 11) Institute of Spectroscopy RAS - ISRAN (Troitsk, Russia); 12) Russian Federal Nuclear Center - All-Russian Institute of Technical Physics - RFNC-VNIITF (Snezhinsk, Chelyabinsk Region, Russia; 13) Institute of Atmospheric Optics - IAO (Tomsk, Russia
