    The central goal of ECLAIRE is to assess how climate change will alter the extent to which air pollutants threaten terrestrial ecosystems. Particular attention has been given to nitrogen compounds, especially nitrogen oxides (NOx) and ammonia (NH3), as well as Biogenic Volatile Organic Compounds (BVOCs) in relation to tropospheric ozone (O3) formation, including their interactions with aerosol components. ECLAIRE has combined a broad program of field and laboratory experimentation and modelling of pollution fluxes and ecosystem impacts, advancing both mechanistic understanding and providing support to European policy makers. The central finding of ECLAIRE is that future climate change is expected to worsen the threat of air pollutants on Europe’s ecosystems. Firstly, climate warming is expected to increase the emissions of many trace gases, such as agricultural NH3, the soil component of NOx emissions and key BVOCs. Experimental data and numerical models show how these effects will tend to increase atmospheric N deposition in future. By contrast, the net effect on tropospheric O3 is less clear. This is because parallel increases in atmospheric CO2 concentrations will offset the temperature-driven increase for some BVOCs, such as isoprene. By contrast, there is currently insufficient evidence to be confident that CO2 will offset anticipated climate increases in monoterpene emissions. Secondly, climate warming is found to be likely to increase the vulnerability of ecosystems towards air pollutant exposure or atmospheric deposition. Such effects may occur as a consequence of combined perturbation, as well as through specific interactions, such as between drought, O3, N and aerosol exposure. These combined effects of climate change are expected to offset part of the benefit of current emissions control policies. Unless decisive mitigation actions are taken, it is anticipated that ongoing climate warming will increase agricultural and other biogenic emissions, posing a challenge for national emissions ceilings and air quality objectives related to nitrogen and ozone pollution. The O3 effects will be further worsened if progress is not made to curb increases in methane (CH4) emissions in the northern hemisphere. Other key findings of ECLAIRE are that: 1) N deposition and O3 have adverse synergistic effects. Exposure to ambient O3 concentrations was shown to reduce the Nitrogen Use Efficiency of plants, both decreasing agricultural production and posing an increased risk of other forms of nitrogen pollution, such as nitrate leaching (NO3-) and the greenhouse gas nitrous oxide (N2O); 2) within-canopy dynamics for volatile aerosol can increase dry deposition and shorten atmospheric lifetimes; 3) ambient aerosol levels reduce the ability of plants to conserve water under drought conditions; 4) low-resolution mapping studies tend to underestimate the extent of local critical loads exceedance; 5) new dose-response functions can be used to improve the assessment of costs, including estimation of the value of damage due to air pollution effects on ecosystems, 6) scenarios can be constructed that combine technical mitigation measures with dietary change options (reducing livestock products in food down to recommended levels for health criteria), with the balance between the two strategies being a matter for future societal discussion. ECLAIRE has supported the revision process for the National Emissions Ceilings Directive and will continue to deliver scientific underpinning into the future for the UNECE Convention on Long-range Transboundary Air Pollution

    International audienceStudy ObjectiveTo describe the surgical management and risks of postoperative complications of patients with urinary tract endometriosis in France in 2017.DesignMulticenter retrospective cohort pilot study.SettingDepartments of gynecology at 31 expert endometriosis centers.PatientsAll women managed surgically for urinary tract endometriosis from January 1, 2017, to December 31, 2017. We distinguished patients with isolated bladder endometriosis or isolated ureteral endometriosis (IUE) from those with endometriosis in both locations (mixed locations [ML]).InterventionsSurgeons belonging to the French Colorectal Infiltrating Endometriosis Study (FRIENDS) group enrolled patients who filled a 24-item questionnaire on the day of the inclusion and 3 months later. Data were collected on operative routes, surgical management, and postoperative complications according to the Clavien-Dindo classification in a single anonymized database.Measurements and Main ResultsA total of 232 patients from 31 centers were included. Isolated bladder endometriosis was found in 82 patients (35.3%), IUE in 126 patients (54.4%), and ML in 24 patients (10.3%). Surgery was performed by laparoscopy, laparotomy, or robot-assisted laparoscopy in 74.1%, 11.2%, and 14.7% of the cases, respectively. Among the 150 ureteral lesions (IUE and ML), 114 were managed with ureterolysis (76%), 28 with ureteral resection (18.7%), 4 with nephrectomy (2.7%), and 23 with cystectomy (15.3%). Concerning bladder endometriosis, a partial cystectomy was performed in 94.3% of the cases. We reported 61 postoperative complications (26.3%): 44 low-grade complications according to the Clavien-Dindo classification (18%), 16 grade III complications (7%), and 1 grade IV complication (peritonitis).ConclusionThe surgical management of ureteral and bladder endometriosis is usually feasible and safe through laparoscopic surgery. Ureteral resection, when necessary, is more strongly associated with laparotomy and with more complications than other procedures. Prospective controlled studies are still mandatory to assess the best surgical management for patients
