Potentiels et leviers pour développer la production et l’utilisation des protéagineux dans le cadre d’une agriculture durable en Bourgogne

A multi-partners strategy is engaged at level of Burgundy-France territory, to evaluate potentials and identify levers for the development of a chain from production to uses of grain legumes. The analysis of genotype x environment interaction and climatic factors is supported by a second year of field trials of grain legumes varieties (pea and faba bean of spring or winter sowing types. The statistical analysis of climatic data over the 1961-2009 period, has allowed to build Burgundy maps of freezing risk and late spring heat stress risk and we are able to suggest pea or faba bean genotypes, better adapted to the region. The sustainability of cropping systems involving or not grain legumes was evaluated according several criteria (agronomy, energy and other input, work organisation). It has confirmed the positive effect of inserting grain legumes, on the reduction (i) of N fertiliser, energy and pesticide uses, (ii) for easier weed control (iii) on the economic bilan assessed over whole cropping system. On 2 sites, « in situ » most measurement of N2Oemissions by soils containing grain legume crop residues were higher than those containing cereal residues. Offering to farmers varieties with good level of stress resistance and good productivity will be a key point for the development of grain legume crops. The economic analysis has identified the potential value of developing contracts between produces and collectors which will secure prices and market. The technical development of a high quality “chain” and its promotion may be valuable provided efforts on traceabilty and on labelling.Une démarche multi-partenaires est engagée sur le territoire de la région Bourgogne, pour évaluer les potentiels et identifier des leviers au développement d’une filière protéagineuse. L’analyse des interactions génotype x environnement et des facteurs climatiques est appuyée par une deuxième année d’expérimentation variétale de protéagineux (pois et féveroles d’hiver et de printemps). Une étude fréquentielle sur la période 1961-2009 a permis de cartographier les risques de gel hivernal et de fortes chaleurs en fin de cycle cultural en Bourgogne et nous pouvons proposer des variétés de pois et de féveroles mieux adaptées à la région. Le volet d’évaluation multicritères de la durabilité des systèmes de culture bourguignons, comparant des systèmes avec et sans protéagineux, a permis de confirmer et de quantifier l’intérêt de l’insertion de protéagineux, qui passe notamment par une diminution de l’IFT moyen et des doses d’azote, une augmentation de la robustesse économique (économie d’engrais azotés et énergie fossile sur l’ensemble de la rotation), la diversification des rotations en offrant de nouvelles possibilités de gestion des adventices. Sur 2 sites, le volet « environnemental » a montré en conditions « in situ », que les émissions de N2O par les sols contenant des résidus de pois ne sont en général pas supérieures à celles des sols contenant des résidus de céréales. La proposition de variétés tolérantes aux principaux stress en culture et de bonne productivité sera une clef essentielle du développement des cultures protéagineuses. L’analyse économique a identifié un intérêt du développement de la contractualisation dans la filière et de la mise en place et de la promotion d’une filière de qualité, en accentuant les exigences en matière de traçabilité et d’étiquetage

The burden of mild asthma: Clinical burden and healthcare resource utilisation in the NOVELTY study

Background: Patients with mild asthma represent a substantial proportion of the population with asthma, yet there are limited data on their true burden of disease. We aimed to describe the clinical and healthcare resource utilisation (HCRU) burden of physician-assessed mild asthma.Methods: Patients with mild asthma were included from the NOVEL observational longiTudinal studY (NOVELTY; NCT02760329), a global, 3-year, real-world prospective study of patients with asthma and/or chronic obstructive pulmonary disease from community practice (specialised and primary care). Diagnosis and severity were based on physician discretion. Clinical burden included physician-reported exacerbations and patient-reported measures. HCRU included inpatient and outpatient visits.Results: Overall, 2004 patients with mild asthma were included; 22.8% experienced ≥1 exacerbation in the previous 12 months, of whom 72.3% experienced ≥1 severe exacerbation. Of 625 exacerbations reported, 48.0% lasted >1 week, 27.7% were preceded by symptomatic worsening lasting >3 days, and 50.1% required oral corticosteroid treatment. Health status was moderately impacted (St George's Respiratory Questionnaire score: 23.5 [standard deviation ± 17.9]). At baseline, 29.7% of patients had asthma symptoms that were not well controlled or very poorly controlled (Asthma Control Test score <20), increasing to 55.6% for those with ≥2 exacerbations in the previous year. In terms of HCRU, at least one unscheduled ambulatory visit for exacerbations was required by 9.5% of patients, including 9.2% requiring ≥1 emergency department visit and 1.1% requiring ≥1 hospital admission.Conclusions: In this global sample representing community practice, a significant proportion of patients with physician-assessed mild asthma had considerable clinical burden and HCRU

Treatable traits in the NOVELTY study

CorrigendumVolume 27, Issue 12, Respirology, pages: 1095-1095. First Published online: November 6, 2022 10.1111/resp.14406International audienceAsthma and chronic obstructive pulmonary disease (COPD) are two prevalent and complex diseases that require personalized management. Although a strategy based on treatable traits (TTs) has been proposed, the prevalence and relationship of TTs to the diagnostic label and disease severity established by the attending physician in a real-world setting are unknown. We assessed how the presence/absence of specific TTs relate to the diagnosis and severity of 'asthma', 'COPD' or 'asthma + COPD'
