Compliance with recommendations of clinical practice in the management of venous thromboembolism in cancer: the CARMEN study

Cancer is associated with venous thromboembolism in 20% of patients. In such patients, thrombosis is difficult to treat, associated with bleeding, recurrence, and death. Specific treatments for venous thromboembolism in cancer are recommended. Guidelines have been implemented in many countries and international guidelines have been recently developed. We evaluated the adhesion to national French guidelines via a survey of cancer patients treated for venous thromboembolism. METHODS: A national cross-sectional observational study evaluated the adhesion to guidelines in hospitalized patients. Good clinical practice was defined as initial 10-day treatment with injectable molecules followed by long-term treatment with low molecular weight heparin for at least 3 months. Demographic data, cancer type, stage, treatment, risk factors and type of thrombosis, were recorded. RESULTS: Five patients were included in 47 centers. Overall adhesion to guidelines was present in 59% (55-63%) of patients (295/500). During initial treatment, adhesion was high (487/496; 98%) but dropped (296/486; 62%) during the long-term maintenance. In patients with renal insufficiency, only a fourth of them received the adequate treatment. A majority of patients had metastatic disease (64%). Cancer sites were gastro-intestinal (25%), gynecologic (23%), pulmonary (21%), hematological (14%), urologic (10%), or other (8%). Lung and hematological malignancies were significantly associated with the highest and lowest rates of adhesion. CONCLUSION: Adhesion to national guidelines for treatment of venous thromboembolism in cancer is not optimal. Good compliance is observed during initial treatment, but drops after 10 days, underlying the need for further education to achieve a better implementation on a national level

Creating Conditions for Harnessing the Potential of Transitions to Agroecology in Europe and Requirements for Policy | Création de conditions pour exploiter le potentiel des transitions vers l'agroécologie en Europe et exigences des politiques | Schaffung von Bedingungen für die Nutzung des agrarökologischen Potenzials in Europa und Anforderungen an die Politik

The European Union’s Farm-to-Fork Strategy sets out its ambitions and approach to how European’s value food sustainability, and the accompanying opportunities for improving the environment as well as the lifestyles and health of EU citizens. It identifies the role of agroecological approaches in primary production as one of the means by which these ambitions can be achieved, through new knowledge and innovations in land management and supply chains. This article concludes the Special Issue on the EU Horizon 2020 projects LIFT and UNISECO, synthesising requirements for the realisation of transitions to agroecology in Europe. It reports the key needs identified of developing human capital, partnerships, cooperation and social capital, access to data and tools, and the links between these needs and relevant EU and national level policies.Les systèmes alimentaires doivent être réorientés pour mieux prendre en compte les interactions avec l’environnement, l’économie, la santé et la société. Les transitions vers des pratiques et des systèmes agricoles agroécologiques peuvent relier les domaines de l’action publique et permettre d'atteindre des objectifs environnementaux, économiques et sociaux. Ces transitions fournissent une perspective pour examiner les politiques, les pratiques et les comportements des acteurs des systèmes agricoles et des chaînes de valeur, l’identifi cation des obstacles à l'adoption et les domaines d’action publique auxquels ils contribuent ou qui présentent des lacunes. Le développement du capital social et humain et de structures de gouvernance qui permettent les transitions vers l’agroécologie est la clé de leurs chances de succès. L’éducation et l’apprentissage tout au long de la carrière sont essentiels pour développer les connaissances et les compétences des jeunes générations de gestionnaires fonciers et d’autres acteurs des chaînes de valeur, tout au long de leur carrière. Le résultat recherché est une compréhension partagée des avantages des pratiques et des systèmes agroécologiques, créant des opportunités pour rééquilibrer les politiques vers la neutralité climatique, inverser la perte de biodiversité et renforcer les droits des citoyens. Pour concrétiser ces opportunités, les politiques et stratégies doivent être cohérentes à tous les niveaux territoriaux et systémiques, et adaptées au lieu, au système, aux personnes et aux étapes des transitions. Dans l’ensemble, elles devraient être conçus pour garantir que tous les citoyens bénéfi cient des transitions vers des systèmes agricoles agroécologiques, sur le long terme, et que personne ni aucun lieu ne soit désavantagé par les processus de changement ou les résultats escomptés.Die Lebensmittelsysteme müssen neu ausgerichtet werden, um den Wechselwirkungen zwischen der Umwelt, der Wirtschaft, der Gesundheit und der Gesellschaft stärker Rechnung zu tragen. Die Umstellung auf agrarökologische Anbaumethoden und - systeme kann die Politikbereiche miteinander verbinden und zur Erreichung ökologischer, wirtschaftlicher und sozialer Ziele beitragen. Sie bieten einen Ansatzpunkt für die Überprüfung der Politik, der Praxis und der Verhaltensweisen der Akteure in landwirtschaftlichen Systemen und Wertschöpfungsketten. Des Weiteren helfen sie bei der Ermittlung von Umsetzungsbarrieren und von Politikbereichen, zu denen sie beitragen oder in denen es Lücken gibt. Die Entwicklung von Sozial- und Humankapital sowie von Governance- Strukturen – die den Übergang zur Agrarökologie ermöglichen – sind ein wesentlicher Erfolgsfaktor. Bildung und lebenslanges Lernen sind ein zentraler Baustein, um die Kenntnisse und Fähigkeiten der jüngeren Generationen von Landwirten und Landwirtinnen und anderen Akteuren in den Wertschöpfungsketten zu entwickeln. Das angestrebte Ergebnis ist ein gemeinsames Verständnis über die Vorteile agrarökologischer Praktiken und Systeme. Dieses schafft Möglichkeiten für eine Neuausrichtung der Politik im Hinblick auf Klimaneutralität, Umkehrung des Verlusts der biologischen Vielfalt und Stärkung der Rechte der Bürger. Zur Verwirklichung der Möglichkeiten, sollten Politiken und Strategien über territoriale und Systemebenen hinweg kohärent und auf Ort, System, Menschen und Phasen des Übergangs zugeschnitten sein. Insgesamt sollten sie so konzipiert sein, dass alle Bürgerinnen und Bürger langfristig von der Umstellung auf agrarökologische Bewirtschaftungssysteme profi tieren und dass niemand oder kein Ort durch den Veränderungsprozess oder das angestrebte Ergebnis benachteiligt wird

Optimizing both catalyst preparation and catalytic behaviour for the oxidative dehydrogenation of ethane of Ni-Sn-O catalysts

[EN] Bulk Ni-Sn-O catalysts have been synthesized, tested in the oxidative dehydrogenation of ethane and characterized by several physicochemical techniques. The catalysts have been prepared by evaporation of the corresponding salts using several additives in the synthesis gel, i.e. ammonium hydroxide, nitric acid, glyoxylic acid or oxalic acid, in the synthesis gel. The catalysts were finally calcined at 500 degrees C in air. Important changes in the catalytic behaviour have been observed depending on the additive. In fact, an important improvement in the catalytic performance is observed especially when some additives, such as glyoxylic or oxalic acid, are used. Thus the productivity to ethylene multiplies by 6 compared to the reference Ni-Sn-O catalyst if appropriate templates are used, and this is the result of an improvement in both the catalytic activity and the selectivity to ethylene. This improved performance has been explained in terms of the decrease of the crystallite size (and the increase in the surface area of catalyst) as well as the modification of the lattice parameter of nickel oxide.The authors would like to acknowledge the DGICYT in Spain (CTQ2015-68951-C3-1-R and CTQ2012-37925-C03-2) for financial support.

The IAXO Helioscope

The IAXO (International Axion Experiment) is a fourth generation helioscope with a sensitivity, in terms of detectable signal counts, at least 104 better than CAST phase-I, resulting in sensitivity on ga¿ one order of magnitude better. To achieve this performance IAXO will count on a 8-coil toroidal magnet with 60 cm diameter bores and equipped with X-ray focusing optics into 0.20 cm2 spots coupled to ultra-low background Micromegas X-ray detectors. The magnet will be on a platform that will allow solar tracking for 12 hours per day. The next short term objectives are to prepare a Technical Design Report and to construct the first prototypes of the hardware main ingredients: demonstration coil, X-ray optics and low background detector while refining the physics case and studying the feasibility studies for Dark Matter axions

The Next Generation of Axion Helioscopes: The International Axion Observatory (IAXO)

The International Axion Observatory (IAXO) is a proposed 4th-generation axion helioscope with the primary physics research goal to search for solar axions via their Primakoff conversion into photons of 1 \u2013 10 keV energies in a strong magnetic field. IAXO will achieve a sensitivity to the axion-photon coupling ga\u3b3 down to a few 710 1212 GeV 121 for a wide range of axion masses up to 3c 0.25 eV. This is an improvement over the currently best (3rd generation) axion helioscope, the CERN Axion Solar Telescope (CAST), of about 5 orders of magnitude in signal strength, corresponding to a factor 3c 20 in the axion photon coupling. IAXO's sensitivity relies on the construction of a large superconducting 8-coil toroidal magnet of 20 m length optimized for axion research. Each of the eight 60 cm diameter magnet bores is equipped with x-ray optics focusing the signal photons into 3c 0.2 cm2 spots that are imaged by very low background x-ray detectors. The magnet will be built into a structure with elevation and azimuth drives that will allow solar tracking for 12 hours each day. This contribution is a summary of our papers [1], [2] and [3] and we refer to these for further details

Conceptual design of the International Axion Observatory (IAXO)

The International Axion Observatory (IAXO) will be a forth generation axion helioscope. As its primary physics goal, IAXO will look for axions or axion-like particles (ALPs) originating in the Sun via the Primakoff conversion of the solar plasma photons. In terms of signal-to-noise ratio, IAXO will be about 4-5 orders of magnitude more sensitive than CAST, currently the most powerful axion helioscope, reaching sensitivity to axion-photon couplings down to a few $\times 10^{-12}$ GeV$^{-1}$ and thus probing a large fraction of the currently unexplored axion and ALP parameter space. IAXO will also be sensitive to solar axions produced by mechanisms mediated by the axion-electron coupling $g_{ae}$ with sensitivity $-$for the first time$-$ to values of $g_{ae}$ not previously excluded by astrophysics. With several other possible physics cases, IAXO has the potential to serve as a multi-purpose facility for generic axion and ALP research in the next decade. In this paper we present the conceptual design of IAXO, which follows the layout of an enhanced axion helioscope, based on a purpose-built 20m-long 8-coils toroidal superconducting magnet. All the eight 60cm-diameter magnet bores are equipped with focusing x-ray optics, able to focus the signal photons into $\sim 0.2$ cm$^2$ spots that are imaged by ultra-low-background Micromegas x-ray detectors. The magnet is built into a structure with elevation and azimuth drives that will allow for solar tracking for $\sim$12 h each day.Comment: 47 pages, submitted to JINS

Physics potential of the International Axion Observatory (IAXO)

We review the physics potential of a next generation search for solar axions:the International Axion Observatory (IAXO). Endowed with a sensitivity todiscover axion-like particles (ALPs) with a coupling to photons as small as$g_{a\gamma}\sim 10^{-12}$ GeV$^{-1}$, or to electrons $g_{ae}\sim$10$^{-13}$,IAXO has the potential to find the QCD axion in the 1 meV$\sim$1 eV mass rangewhere it solves the strong CP problem, can account for the cold dark matter ofthe Universe and be responsible for the anomalous cooling observed in a numberof stellar systems. At the same time, IAXO will have enough sensitivity todetect lower mass axions invoked to explain: 1) the origin of the anomalous"transparency" of the Universe to gamma-rays, 2) the observed soft X-ray excessfrom galaxy clusters or 3) some inflationary models. In addition, we reviewstring theory axions with parameters accessible by IAXO and discuss theirpotential role in cosmology as Dark Matter and Dark Radiation as well as theirconnections to the above mentioned conundrums

Future axion searches with the International Axion Observatory (IAXO)

The International Axion Observatory (IAXO) is a new generation axion helioscope aiming at a sensitivity to the axion-photon coupling of ga\u3b3 3c few 7 10-12 GeV-1, i.e. 1-1.5 orders of magnitude beyond the one achieved by CAST, currently the most sensitive axion helioscope. The main elements of IAXO are an increased magnetic field volume together with extensive use of x-ray focusing optics and low background detectors, innovations already successfully tested in CAST. Additional physics cases of IAXO could include the detection of electron-coupled axions invoked to explain the white dwarf cooling, relic axions, and a large variety of more generic axion-like particles (ALPs) and other novel excitations at the low-energy frontier of elementary particle physics

HE-LHC: The High-Energy Large Hadron Collider – Future Circular Collider Conceptual Design Report Volume 4

In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100 km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100 TeV. Its unprecedented centre-of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries
