    Introduction: Renal cell carcinoma (RCC) is the most common form of kidney cancer with >30% already metastatic at diagnosis. For patients who fail tyrosine kinase inhibitor (TKI) therapy, the Italian Medical Oncology Association recommends (level IA) nivolumab and cabozantinib. The aim of this study was to compare the cost-effectiveness of cabozantinib with nivolumab for treatment of adult patients with mRCC following prior TKI therapy in Italy. Methods: A partitioned survival (area under the curve) model was developed for the Italian medical environment. Cost-effectiveness was assessed from the Italian National Healthcare Service (SSN) perspective over a 30-year time horizon (annual discount: 3% rate). In the absence of head-to-head studies, clinical evidence was based on results of network meta-analysis. Health-state-related utilities were informed by EQ-5D data from the METEOR study. Resource use and costs were obtained from published sources. Results: Treatment with cabozantinib dominates nivolumab across a 30-years time horizon. In the reference case, treatment with cabozantinib results in an incremental 0.268 quality-adjusted life years (QALY) and an incremental 0.349 life years (LY) gained with a total saving, for the Italian SSN, of €5,605 compared to nivolumab over 30 years. Cabozantinib is associated with gains in quality adjusted life years versus nivolumab, in all analyses. Results were shown to be sensitive to drug prices variation and robust when altering other parameters. Discussion: Cabozantinib represents an efficient option in the management of mRCC after initial TKI-therapy in Italy. Drug prices impact final results, and this must be carefully considered, especially considering the confidential discounts and outcome/financial-based agreements currently in place in Italy

    Entre mobilisation et modération : les forestiers face aux ambiguïtés de la bioéconomie

    National audienceCette communication questionne l'effet des dispositifs de soutien à une mobilisation accrue de la biomasse sur les pratiques sylvicoles des propriétaires privés. Confrontés à des problèmes structurels, nous nous demandons si ces derniers se montrent sensibles à la convergence attendue des objectifs économiques et environnementaux portée par la bioéconomie. Pour éprouver ce questionnement, nous croisons la théorie des pratiques et celle des innovations sociotechniques. Se plaçant à un niveau « méso » du social, ces corpus abordent la problématique du changement de manière complémentaire. Tandis que la théorie des pratiques questionne la manière dont des acteurs réceptionnent de nouvelles pratiques, les approches sociotechniques se focalisent sur le travail d'enrôlement effectué par les prescripteurs. Cette discussion analytique s'appuie sur deux cas d'études. Le premier s'intéresse aux comportements des propriétaires de la forêt des Landes de Gascogne face à l'essor des marchés du bois-énergie et la demande de mobilisation des souches du pin maritime. Le deuxième cas questionne la manière dont un programme d'action visant à mobiliser de la biomasse en améliorant des peuplements dépérissant affecte les pratiques sylvicoles dans une zone forestière « sous-exploitée ». La méthodologie conjugue enquête qualitative auprès d'acteurs de la filière et enquête quantitative auprès d'un échantillon de propriétaires. Nos recherches montrent que si certains propriétaires adaptent leurs pratiques, ils ne le font pas nécessairement au nom de la transition énergétique et écologique. De plus, alors que l'offre sylvicole converge vers des scénarios d'intensification, les propriétaires privilégient des options moins radicales. Longtemps perçue comme une preuve de frilosité, cette résistance au changement pourrait finalement contribuer à inscrire la bio-économie dans une trajectoire soutenabl

    Strategies for mitigation of nitrogen environmental impact from swine production Estratégias para minimização do impacto ambiental do azoto em suinicultura

    This work presents strategies that can be implemented in order to minimize the environmental impact of swine slurry on soil, water, and air. This reduction can be achieved through decrease in nitrogen excretion and ammonia emissions. The correct feed formulation according to animal requirements, the increase in diet digestibility and improvement in animal performance can reduce nitrogen excretion. The use of additives either in the diet or in the manure as well as some equipment rearrangements can reduce ammonia emission.<br>Neste trabalho são apresentadas estratégias que podem ser implementadas para minimizar o impacto ambiental dos efluentes da produção suína sobre o solo, a água e a atmosfera. Esta redução pode ser obtida com a excreção de azoto e a sua volatilização. A formulação mais ajustada às necessidades dos animais, o aumento da digestibilidade da dieta e a melhoria do desempenho dos animais podem reduzir a excreção de azoto. O uso de aditivos nas dietas ou nos dejectos e alterações nas instalações pode reduzir a volatilização da amónia
