OBJECT
The widespread implementation of the embolic agent Onyx has changed the endovascular management of cerebral arteriovenous malformations (AVMs). Recent data suggest that outcomes following embolization and resection may have worsened in the Onyx era. It has been hypothesized that there may be increased complications with Onyx embolization and increased surgical aggressiveness in patients treated with Onyx. In this study the authors analyzed their institutional experience with the endovascular treatment of cerebral AVMs prior to and after the introduction of Onyx to determine factors associated with periprocedural neurological morbidity and mortality.

METHODS
A retrospective review was performed of all patients with cerebral AVMs undergoing embolization at the Barrow Neurological Institute from 1995 to 2012.

RESULTS
Endovascular treatment of 342 cerebral AVMs was performed over 446 treatment sessions (mean age 37.8 years, range 1–83 years). Clinical presentation included hemorrhage in 47.6%, seizures in 21.9%, headaches in 11.1%, and no symptoms in 10% of cases. The endovascular pretreatment strategy was preoperative in 78.9%, preradiosurgery in 9.1%, palliative in 5.3%, targeted in 4.4%, and curative in 2.3%. The median Spetzler-Martin grade was III. The mean number of arteries embolized was 3.5 (range 0–13 arteries), and the mean number of treatment sessions was 1.3 (range 1–4 sessions). Onyx was used in 105 AVMs (30.7%), and N-butyl cyanoacrylate (NBCA) without Onyx was used in 229 AVMs (67%). AVMs treated with Onyx had a higher mean number of arterial pedicles embolized than did NBCA cases (4.3 ± 2.7 vs 3.2 ± 2.4, respectively; p < 0.001) and a greater number of sessions (1.5 ± 0.7 vs 1.2 ± 0.5, respectively; p < 0.05). Unexpected immediate postprocedural permanent neurological deficits were present in 9.6% of AVMs, while transient deficits were present in 1.8%. There was 1 death (0.3%). Spetzler-Martin grade was not associated with differences in outcome, as permanent neurological deficits were observed in 12%, 9%, 13%, 11%, and 13% of AVMs for Spetzler-Martin Grades I–V, respectively (p = 0.91). The use of Onyx compared with NBCA was not associated with differences in periprocedural morbidity (p = 0.23). This lack of a difference persisted even when controlling for number of arteries and sessions (p = 0.14). Sex was not associated with differences in outcome.

CONCLUSIONS
Permanent and transient postprocedural neurological deficits were noted in 9.6% and 1.8% of all cases, respectively. AVM grade was not associated with endovascular outcome. Despite the greater number of sessions required and arteries embolized for Onyx cases, there was no statistically significant difference in the risk of neurological deficits following cerebral AVM embolization with Onyx and NBCA.
Automutilations psychotiques : entre coupure et écriture
Authors: Druel Gwénola 
Published: March 2015

Les automutilations psychotiques qui surgissent en institution laissent bien souvent les professionnels désemparés, impuissants face à ces passages à l’acte d’« attaque » du corps dans le réel, auxquels ils ne peuvent donner sens. Aussi, interroger les coordonnées du déclenchement de tels passages à l’acte s’avère nécessaire et nécessite un examen psychopathologique minutieux de ce qui se présente comme retour du réel du corps dans notre modernité. Au-delà, la clinique de l’automutilation interroge la notion même de corps et du rapport du sujet au monde, à l’autre. L’auteur démontre en quoi le passage de la coupure du corps, à la trace, au trait, voire à l’écriture, sur le corps sont autant de tentatives de « nouage » pour border, faire tenir le corps. Ces écritures du réel sur le corps sont dès lors, dans certains cas, à envisager comme solutions « autothérapeutiques » avec leur effet d’apaisement pour le sujet.
« C’est un jeu pour la survie » : le syndrome de Godot dans la démence
Authors: Engasser Ophélie 
Published: March 2015

Les démences sont des affections neurologiques évolutives qui mènent, dans leurs stades évolués, à l’expérience de la détresse existentielle. L’agir comportemental est considéré ici comme un recours offrant au sujet une modalité de résolution de la détresse. Cet article s’intéresse plus particulièrement au syndrome de Godot, peu exploité dans la littérature gérontologique, qui témoignerait d’une temporalité défaillante engendrant la répétition. Ce syndrome tient son nom de la célèbre pièce de Samuel Beckett, En attendant Godot , dont il disait qu’elle est « un jeu pour la survie ». À partir de considérations théorico-cliniques et littéraires conduisant à une problématisation des enjeux de ce syndrome, l’auteur invite à penser une éthique du soin psychique.

Cet article s’intéresse à l’Inde et explore son positionnement sur la scène internationale et l’émergence des politiques nationales.
Contributions actuelles et virtuelles des droits de la personne aux décisions judiciaires et à l’évolution de la justice pénale
Authors: Garcia Margarida 
Published: March 2015

Prenant appui sur une recherche empirique qualitative, l’article montre la façon dont les acteurs judiciaires se représentent l’apport des « droits de la personne » dans le processus de prise de décisions et dans l’évolution de la justice pénale. La démarche s’inscrit dans une approche sociologique du droit qui privilégie une mise en relation des points de vue interne et externe au droit dans la production de connaissances. Méthodologiquement, l’analyse repose sur des entretiens réalisés auprès de juges et de procureurs de la couronne au Canada et au Portugal. L’analyse de ces données a permis d’identifier quatre contributions attribuées aux droits de la personne dans la prise de décisions : ils protègent les personnes accusées, ils permettent le contrôle de la validité des normes, ils stimulent l’évolution des principes du droit et enfin, ils facilitent l’adaptation du système à la société ou à son environnement. Encadrés d’un point de vue théorique par certains outils empruntés aux travaux de Niklas Luhmann et de Gunther Teubner, les résultats présentés permettent de mieux observer et comprendre la place et le rôle qu’occupent les « droits de la personne » dans la prise de décision judiciaire moderne, leurs contributions et aussi leurs limites.

Authors: Henriot Arthur , Glachant Jean-Michel 
Published: March 2015

Cet article analyse l’impact de l’intégration des renouvelables dans les marchés de l’électricité en Europe. La nature de ce problème d’efficacité économique est analysée à la lueur des contributions existantes dans la littérature. Les éventuels obstacles à un fonctionnement sous des règles de marché communes à tous les producteurs sont exposés en tenant compte des différences fondamentales entre producteurs traditionnels et renouvelables. L’article s’intéresse ensuite aux différents outils proposés pour assurer le fonctionnement du marché dans un contexte de faible prévisibilité et de variabilité de la production des renouvelables. Les solutions suivantes sont examinées : unités de temps plus précises, nouvelles limites aux prix de gros, meilleure articulation de la séquence de marchés d’ajustement, introduction de mécanismes de rémunération de capacité. Nous nous intéressons également à la redéfinition de l’espace, depuis la tarification nodale jusqu’à la possible émergence d’une multitude de marchés locaux.

Authors: Mathy Sandrine , Fink Meike , Bibas Ruben 
Published: March 2015

Cet article revient sur l’utilité des scénarios bas carbone en France dans la décision publique. Celle-ci peut être le scénario en lui-même et son contenu en termes de trajectoire technico-énergétique (product-oriented) et c’est dans cette catégorie que s’inscrivent les scénarios versés au débat énergie en France en 2013 ; mais son objectif peut également résider dans le procédé (process-oriented) même d’élaboration du scénario pour faire émerger des consensus ou des niveaux minimaux d’accords. Dans cette optique, nous élaborons des scénarios à l’aide d’une méthode de concertation avec une trentaine de parties prenantes issues aussi bien du secteur privé, du secteur public et de l’État, des ONG, des associations de consommateurs, des syndicats, des banques ou des collectivités territoriales. Celles-ci sélectionnent des politiques qu’elles considèrent acceptables pour atteindre l’objectif de Facteur 4 et qui sont intégrées dans le modèle technico-économique de simulation Imaclim-R France selon un scénario acceptabilité forte AF et un scénario acceptabilité modérée AM. Dans le scénario AF, les émissions diminuent en 2050 entre 58 et 72 % et dans le scénario AM entre 68 et 81 % selon les hypothèses faites sur les prix de l’énergie. Les mesures de réduction des émissions, dont la plus emblématique est la taxe carbone, sont bénéfiques pour l’emploi et la croissance économique. Elles permettent en outre de réduire rapidement et durablement le budget des ménages dédié aux services énergétiques. Ce résultat constitue un socle solide sur lequel construire l’acceptabilité des trajectoires Facteur 4 et le processus un cadre pour renforcer l’apprentissage collectif autour de l’acceptabilité des politiques climatiques.

Abstract
Objective: The objective of the study was to assess the incidence and pattern of drug-drug interactions (DDIs) in hypertensive patients by using Micromedex and Medscape databases.
Materials and Methods: A prospective observational study was carried out in a superspeciality hospital setting in South India for period of 9 months. Hypertensive patients who admitted into the hospital with the age more than 18 years, received more than 3 drugs per prescription and length of hospital stay for more than 24 hours were included in the study. An appropriate data was collected and assessed for DDIs with the help of Micromedex and Medscape databases.
Results: A total of 227 patients were enrolled during the study period. Among the 227 patients, 48 of them developed 53 clinically significant DDIs. Out of 48 patients, most of them were in the age-group of 50-60 years [18 (37.49%)]. The percentage of DDIs were higher in males [30 (62.5%)] compared to females [18 (37.5%)]. The most common drugs responsible for DDIs in the present study were Insulin [18 (33.96%)] followed by Metoprolol [10 (18.86%)], Torsemide [8 (15.09%)], and Hydrochlorothiazide [8 (15.09%)]. The most commonly interacting pairs were Ciprofloxacin-Insulin [6 (11.32%)], followed by Metoprolol-Insulin [4 (7.54%)] and Atenolol-Insulin [4 (7.54%)]. The most common consequences of interacting pairs were reduced serum potassium levels and hyperglycemia.
Conclusion: The overall incidence rate of DDIs was found to be 21.14% and the increasing number of co-morbidities ( P ≤ 0.003) and polypharmacy ( P ≤ 0.002) were the risk factor for the development of significant number of DDIs.

A study of thunderstorm microphysical properties and lightning flash counts associated with terrestrial gamma‐ray flashes

Published: March 2015

AbstractThe terrestrial gamma ray flash (TGF) is an emission of highly energetic radiation produced by or at least in close association with lightning. Previous investigations attempted to isolate the production mechanisms and production altitude(s) of TGFs as well as macrophysical characteristics, while thunderstorm microphysical characteristics were largely ignored. This investigation into thunderstorms and their hydrometeor and flash characteristics utilize temporal and spatial coincident satellite passes between the Reuven Ramaty High Energy Solar Spectroscopic Imager and the Tropical Rainfall Measuring Mission to determine the bulk (or footprint) microphysical properties of two types of study events, the thunderstorm complexes which are associated with TGFs (TGF case) and the thunderstorm complexes which did not produce a TGF detected by Reuven Ramaty High Energy Solar Spectroscopic Imager during the pass (non‐TGF case). Results are presented for two different comparison methods. The first case utilizes geographic region weighted by TGF distribution, and the second is based on TGF percentage of occurrence when compared to total flash count of data set. Results show that the associated storms around the TGF location possess differences in the hydrometeor concentrations: cloud liquid water, cloud ice, precipitation water, and precipitation ice. These results take place at different levels of the atmosphere, including the mixed phase region. Additionally, results will show that TGFs are a consistent percentage of observed flashes as the rate of TGFs as a function of Lightning Imaging Sensor flash count is relatively constant.
Intercalibration of microwave temperature sounders using radio occultation measurements
Authors: Isoz O. , Buehler S. A. , Eriksson P. 
Published: March 2015

AbstractThis is a study of the usefulness of radio occultation (RO) data for intercomparing different microwave temperature (MWT) sounding instruments. The RO data used are from the Global Navigational Satellite System Receiver for Atmospheric Sounding on the Metop‐A and B satellites. The MWT sounders investigated are the Advanced Microwave Sounding Unit‐A instruments on the satellites NOAA 15, 16, and 18 and Metop‐A. We collocate RO and MWT data and then use these collocations to study various aspects of the MWT instruments. In addition, two different versions of the MWT data are compared: standard operational data (OPR) and the NOAA Integrated Microwave Intercalibration Approach data (IMICA). The time series of monthly mean differences shows that there are robust patterns for each satellite and data version, which mostly drift only slowly over time. The intersatellite spread, measured by the standard deviation of the yearly mean values by all satellites, is between 0.1 and 0.4 K, depending on channel, with no significant differences between OPR and IMICA data. The only notable exception is Channel 8 of NOAA 16, which appears to have a time‐varying offset of 0.5–1 K relative to the other instruments. At this point it is not clear whether this deviation is real or a sampling artifact, so further study is needed. Due to the large number of collocations used, it is possible to also investigate the scene brightness and scan angle dependence of the MWT bias (relative to RO). First results of such an analysis are presented and discussed. Particularly, the investigation of the scan angle dependence is novel, since this bias pattern is difficult to assess without RO data. Further work is needed on these angular dependences, before conclusions are robust enough to include in data recalibration efforts, but our overall conclusion is that RO collocations are a powerful tool for intercomparing MWT sounders.

AbstractWestern U.S. near‐surface ozone (O3) concentrations are sensitive to transported background O3 from the eastern Pacific free troposphere, as well as U.S. anthropogenic and natural emissions. The current 75 ppbv U.S. O3 primary standard may be lowered soon, hence accurately estimating O3 source contributions, especially background O3 in this region has growing policy‐relevant significance. In this study, we improve the modeled total and background O3, via repartitioning and redistributing the contributions from nonlocal and local anthropogenic/wildfires sources in a multi‐scale satellite data assimilation system containing global Goddard Earth Observing System–Chemistry model (GEOS‐Chem) and regional Sulfur Transport and dEposition Model (STEM). Focusing on NASA's ARCTAS (Arctic Research of the Composition of the Troposphere from Aircraft and Satellites) field campaign period in June–July 2008, we first demonstrate that the negative biases in GEOS‐Chem free simulation in the eastern Pacific at 400–900 hPa are reduced via assimilating Aura‐Tropospheric Emission Spectrometer (TES) O3 profiles. Using the TES‐constrained boundary conditions, we then assimilated into STEM the tropospheric nitrogen dioxide (NO2) columns from Aura‐Ozone Monitoring Instrument to indicate U.S. nitrogen oxides (NOx = NO2 + NO) emissions at 12 × 12 km2 grid scale. Improved model skills are indicated from cross validation against independent ARCTAS measurements. Leveraging Aura observations, we show anomalously high wildfire NOx emissions in this summer in Northern California and the Central Valley while lower anthropogenic emissions in multiple urban areas than those representing the year of 2005. We found strong spatial variability of the daily maximum 8 h average background O3 and its contribution to the modeled total O3, with the mean value of ~48 ppbv (~77% of the total).
Gold‐Catalyzed Hydroarylation of Alkynes
Authors: Muratore Michael E. , Echavarren Antonio M. 
Published: March 2015

AbstractHydroarylations, also called alkenylations of (hetero)arenes are important transformations in organic chemistry. The recent development of gold‐catalyzed processes to achieve such transformations has added a new tool in the chemist's toolbox. Thus, the hydroarylations of alkynes under gold catalysis are reviewed from a mechanistic and practical point of view. Both intramolecular and the more challenging intermolecular alkenylations are considered and described in a comprehensive account that includes detailed mechanisms as well as supporting theoretical calculations when relevant. This chapter also aims at illustrating the reactivity of internal and external alkynes which may differ in certain cases, as well as the various reactivities encountered with heteroarenes and arenes. The employment of supported gold catalysts to perform this type of transformations is also discussed in the last section of the chapter.
Directional Statistics: Introduction
Authors: Gatto Riccardo , Jammalamadaka S. Rao 
Published: March 2015

Abstract
In many of the natural and physical sciences, measurements are directions, either in two or three dimensions. The analysis of directional data relies on specific statistical models and procedures, which differ from the usual models and methodologies of Cartesian data. This article briefly introduces statistical models and inference for this type of data. The basic von Mises–Fisher distribution is introduced and nonparametric methods such as goodness‐of‐fit tests are presented. Further references are given for exploring related topics.
