Abstract
Lepidopteran species can be both pests and also beneficial pollinators for agricultural crops. However, despite these important roles, the effects of pesticides on this diverse taxa are relatively understudied. To facilitate the assessment of pesticides and other chemical hazards on this taxa, we present a novel bioassay capable of testing chemical sensitivity to lepidopteran larvae through dietary exposure. We used Mamestra brassicae caterpillars as a model lepidopteran and tested their sensitivity for the organophosphate insecticide chlorpyrifos. We exposed larvae to an artificial diet spiked with chlorpyrifos and monitored survival over time, as well as weight change over a 96-hour exposure period. To test the repeatability and reliability of the developed bioassay, the experiment was repeated three times. The survival in time data collected enabled analysis with the General Unified Threshold of Survival (GUTS) model, recently recognized by EFSA as a ready-to-use tool for regulatory purposes. The GUTS modelling was used to derive a set of relevant toxicokinetic and toxicodynamic parameters relating to the larval response to exposure over time. We found that across the three repeats studies there was no more than a threefold difference in LC₅₀ values (13.1, 18.7 and 8.1 mg/Kg) at 48 h and fourfold difference at 96 h, highlighting the repeatability of the bioassay. We also highlighted the potential of the method to observe sub-lethal effects such as changes in weight. Finally, we discuss the applications of this new bioassay method to chemical risk assessments and its potential for use in other scenarios, such as mixture or pulsed exposure testing.

Abstract
The Dynamic Energy Budget theory (DEB) enables ecotoxicologists to model the effects of chemical stressors on organism life cycles through the coupling of toxicokinetic-toxicodynamic (TK-TD) models. While good progress has been made in the application of DEB-TKTD models for aquatic organisms, applications for soil fauna are scarce, due to the lack of dedicated experimental designs suitable for collecting the required time series effect data. Enchytraeids (Annelida: Clitellata) are model organisms in soil ecology and ecotoxicology. They are recognised as indicators of biological activity in soil, and chemical stress in terrestrial ecosystems. Despite this, the application of DEB-TKTD models to investigate the impact of chemicals has not yet been tested on this family. Here we assessed the impact of the pyrethroid insecticide cypermethrin on the life cycle of Enchytraeus crypticus. We developed an original experimental design to collect the data required for the calibration of a DEB-TKTD model for this species. E. crypticus presented a slow initial growth phase that has been successfully simulated with the addition of a size-dependent food limitation for juveniles in the DEB model. The DEB-TKTD model simulations successfully agreed with the data for all endpoints and treatments over time. The highlighted physiological mode of action (pMoA) for cypermethrin was an increase of the growth energy cost. The threshold for effects on survival was estimated at 73.14 mg kg- 1, and the threshold for effects on energy budget (i.e., sublethal effects) at 19.21 mg kg- 1. This study demonstrates that DEB-TKTD models can be successfully applied to E. crypticus as a representative soil species, and may improve the ecological risk assessment for terrestrial ecosystems, and our mechanistic understanding of chemical effects on non-target species.

Abstract
INTRODUCTION In 2018, the French High Authority of Health (HAS) included a "time-out" phase in the latest version of the checklist for the operating room in order to improve the safety of operated patients. The aim of this study is to evaluate the practice of French urologists concerning the check list (CL) of the operating room. MATERIAL AND METHODS A survey of 30 items was developed by the committee of accreditation of the French Association of Urology (AFU) and other contributors. It was centered on the characteristics of the urologists, the details of application of the CL, and the evaluation of the current version. After validation, the questionnaire was emailed as an online form in July 2021 for all the members of the AFU and AFUF. RESULTS Overall, 369 form the 1700 contacted urologists responded to the survey. The majority were more than 40 years old (70.11%) and less than 20 year of experience (54.49%). The engagement in individual or team accreditation was observed in 222 (60.7%) and 145 (39.84%) urologists, respectively. Almost half of them were present at the beginning of the CL (47.18%), and prescribed postoperative medication with the anesthesiologist (55.56%). The CL has modified the practice in 47.54%, however, with greater administrative burden, and 80% preferred that the AFU adapts the CL to the urology field. CONCLUSION The practice of CL between urologists is variable. On multivariate analysis, the engagement in team accreditation was the only variable to influence the practice of time out.

Abstract
Before plant protection product (PPP) marketing authorization, a risk assessment for nontarget soil organisms (e.g., earthworms) is required as part of Regulation (EC) No. 1107/2009. Following a stepwise approach, higher tier earthworm field studies are needed if they cannot demonstrate low long-term risk based on laboratory studies. The European guidance for terrestrial ecotoxicology refers to ISO guideline 11268-3 as a standard to conduct earthworm field studies. Assessment of such studies may be challenging, as no European harmonized guidance is available to properly analyze the accuracy, representativeness, and appropriateness of experimental designs, as well as the statistical analysis robustness of results and their scientific reliability. Following the ISO guideline 11268-3, a field study was performed in 2016-2017 (Versailles, France). An assessment of the first year of this field study was performed in agreement with the quality criteria provided in 2006 in the guidance document published by de Jong and collaborators and recommendations by Kula and collaborators that allows describing the protocol and results of earthworm field studies. Not only did we underline the importance of a detailed analysis of raw data on the effects of pesticides on earthworms in field situations, but we also provided recommendations to harmonize protocols for assessing higher tier field studies devoted to earthworms to advance a better assessment of PPP fate and ecotoxicity. In particular, we provided practical field observations related to the study design, pesticide applications, and earthworm sampling. Concurrently, in addition to the conventional earthworm community study, we propose carrying out an assessment of soil function (i.e., organic matter decomposition, soil structuration, etc.) and calculating diversity indices to obtain information about earthworm community dynamics after the application of PPPs. Finally, through field observations, any relevant observation of external and/or internal recovery should be reported. Integr Environ Assess Manag 2023;19:254-271. © 2022 The Authors.

Abstract
The assessment of chemical mixture toxicity is one of the major challenges in ecotoxicology. Chemicals can interact, leading to more or less effects than expected, commonly named synergism and antagonism respectively. The classic ad hoc approach for the assessment of mixture effects is based on dose-response curves at a single time point, and is limited to identifying a mixture interaction but cannot provide predictions for untested exposure durations, nor for scenarios where exposure varies in time. We here propose a new approach using toxicokinetic-toxicodynamic modelling: The General Unified Threshold model of Survival (GUTS) framework, recently extended for mixture toxicity assessment. We designed a dedicated mechanistic interaction module coupled with the GUTS mixture model to i) identify interactions, ii) test hypotheses to identify which chemical is likely responsible for the interaction, and finally iii) simulate and predict the effect of synergistic and antagonistic mixtures. We tested the modelling approach experimentally with two species (Enchytraeus crypticus and Mamestra brassicae) exposed to different potentially synergistic mixtures (composed of: prochloraz, imidacloprid, cypermethrin, azoxystrobin, chlorothalonil, and chlorpyrifos). Furthermore, we also tested the model with previously published experimental data on two other species (Bombus terrestris and Daphnia magna) exposed to pesticide mixtures (clothianidin, propiconazole, dimethoate, imidacloprid and thiacloprid) found to be synergistic or antagonistic with the classic approach. The results showed an accurate simulation of synergistic and antagonistic effects for the different tested species and mixtures. This modelling approach can identify interactions accounting for the entire time of exposure, and not only at one time point as in the classic approach, and provides predictions of the mixture effect for untested mixture exposure scenarios, including those with time-variable mixture composition.

Abstract
Pesticides may harm soil organisms such as earthworms and enchytraeids, but knowledge is lacking on their relative sensitivity to these chemicals and the consequences on soil functions. The aim of this study was to assess the impact of exposure to a commercial fungicide formulation (Swing® Gold, containing dimoxystrobin and epoxiconazole) on the function of earthworms (Aporrectodea caliginosa) and enchytraeids (Enchytraeus buchholzi) in soil organic matter (SOM) mineralization. The soil organisms were incubated alone and together in a 26-day laboratory experiment. At the recommended field rate, the fungicide induced a decrease in the SOM mineralization and a delay in the maximum daily CO2 emissions compared to the control soil without fungicide. Soil fauna also influenced SOM mineralization with a higher cumulated CO2 release after 26 days in the control soil with earthworms (by 21%) than without fauna. When both earthworms and enchytraeids were present, SOM mineralization did not increase, and there was a negative effect on earthworm weight gain. Finally, an alteration of fauna influence with treatment was observed from day 19, meaning that the effect of fauna on SOM mineralization changed with fungicide treatment. Earthworms no longer promoted SOM mineralization when fungicide was present at three-fold the recommended field rate. The effects of enchytraeids on SOM mineralization were similar with and without fungicide exposure. This study underlines the importance of considering the relative sensitivity of soil organisms to environmental factors and interactions between them when assessing soil functioning.

Abstract
To better understand nanoplastic effects, the potential for surface functionalization and dissolve organic matter eco-corona formation to modify the mechanisms of action and toxicity of different nanoplastics needs to be established. Here, we assess how different surface charges modifying functionalization (postive (+ve) aminated; neutral unfunctionalized; negative (-ve) carboxylated) altered the toxicity of 50 and 60 nm polystyrene nanoplastics to the nematode Caenorhabditis elegans. The potency for effects on survival, growth, and reproduction reduced in the order +ve aminated > neutral unfunctionalized ≫ -ve carboxylated with toxicity >60-fold higher for the +ve than -ve charged forms. Toxicokinetic-toxicodynamic modeling (DEBtox) showed that the charge-related potency was primarily linked to differences in effect thresholds and dose-associated damage parameters, rather than to toxicokinetic parameters. This suggests that surface functionalization may change the nature of nanoplastic interactions with membrane and organelles leading to variations in toxicity. Eco-corona formation reduced the toxicity of all nanoplastics indicating that organic molecule associations may passivate surfaces. Between particles, eco-corona interactions resulting in more equivalent effects; however, even despite these changes, the order of potency of the charged forms was retained. These results have important implications for the development of future grouping approaches.

Abstract
Current methods to assess the impact of chemical mixtures on organisms ignore the temporal dimension. The General Unified Threshold model for Survival (GUTS) provides a framework for deriving toxicokinetic-toxicodynamic (TKTD) models, which account for effects of toxicant exposure on survival in time. Starting from the classic assumptions of independent action and concentration addition, we derive equations for the GUTS reduced (GUTS-RED) model corresponding to these mixture toxicity concepts and go on to demonstrate their application. Using experimental binary mixture studies with Enchytraeus crypticus and previously published data for Daphnia magna and Apis mellifera, we assessed the predictive power of the extended GUTS-RED framework for mixture assessment. The extended models accurately predicted the mixture effect. The GUTS parameters on single exposure data, mixture model calibration, and predictive power analyses on mixture exposure data offer novel diagnostic tools to inform on the chemical mode of action, specifically whether a similar or dissimilar form of damage is caused by mixture components. Finally, observed deviations from model predictions can identify interactions, e.g., synergism or antagonism, between chemicals in the mixture, which are not accounted for by the models. TKTD models, such as GUTS-RED, thus offer a framework to implement new mechanistic knowledge in mixture hazard assessments.

Abstract
The representativeness of laboratory studies of the fate of pesticides in soil in field conditions is questionable. This study aimed at comparing the dissipation and bioavailability to earthworms of two fungicides, dimoxystrobin (DMX) and epoxiconazole (EPX), over 12 months under laboratory and field conditions. In both approaches, the fungicides were applied to the same loamy soil as a formulated mixture at several concentrations. We determined total DMX and EPX concentrations in the soil using exhaustive extraction, their environmental availability using mild extraction and their bioavailability through internal concentrations in exposed earthworms. The initial fungicide application appeared as much better controlled in terms of dose and homogeneity in the laboratory than in the field. One year after application, a similar dissipation rate was observed between the laboratory and field experiments (ca 80% and 60% for DMX and EPX, respectively). Similarly, the ratio of available/total concentrations in soil displayed the same trend whatever the duration and the conditions (field or lab), EPX being more available than DMX. Finally, the environmental bioavailability of the two fungicides to earthworms was heterogeneous in the field, but, in the laboratory, the bioaccumulation was evidenced to be dose-dependent only for DMX. Our findings suggest that the actual fate of the two considered fungicides in the environment is consistent with the one determined in the laboratory, although the conditions differed (e.g., presence of vegetation, endogeic earthworm species). This study allowed better understanding of the fate of the two considered active substances in the soil and underlined the need for more research dedicated to the link between environmental and toxicological bioavailability.

Abstract
Recent EFSA (European Food Safety Authority) reports highlighted that the ecological risk assessment of pesticides needed to go further by taking more into account the impacts of chemicals on biodiversity under field conditions. We assessed the effects of two commercial formulations of fungicides separately and in mixture, i.e., Cuprafor Micro® (containing 500 g kg-1 copper oxychloride) at 4 (C1, corresponding to 3.1 mg kg-1 dry soil of copper) and 40 kg ha-1 (C10), and Swing® Gold (50 g L-1 epoxiconazole EPX and 133 g L-1 dimoxystrobin DMX) at one (D1, 5.81 10-2 and 1.55 10-1 mg kg-1 dry soil of EPX and DMX, respectively) and ten times (D10) the recommended field rate, on earthworms at 1, 6, 12, 18 and 24 months after the application following the international ISO standard no. 11268-3 to determine the effects on earthworms in field situations. The D10 treatment significantly reduced the species diversity (Shannon diversity index, 54% of the control), anecic abundance (29% of the control), and total biomass (49% of the control) over the first 18 months of experiment. The Shannon diversity index also decreased in the mixture treatment (both fungicides at the recommended dose) at 1 and 6 months after the first application (68% of the control at both sampling dates), and in C10 (78% of the control) at 18 months compared with the control. Lumbricus terrestris, Aporrectodea caliginosa, Aporrectodea giardi, Aporrectodea longa, and Allolobophora chlorotica were (in decreasing order) the most sensitive species to the tested fungicides. This study not only addressed field ecotoxicological effects of fungicides at the community level and ecological recovery, but it also pinpointed some methodological weaknesses (e.g., regarding fungicide concentrations in soil and statistics) of the guideline to determine the effects on earthworms in field situations.

Abstract
Erectile dysfunction varied by country, affecting between 20 to 40% of men aged 60 and 69 and more than 50% of men aged over 75. Our objective was to evaluate the habits of urologists in 2018 and also evaluate the need for additional, objective tools to aid physicians when providing care. A questionnaire was sent from the French Urology Association to 1158 physicians between November and December 2018. In all, 177 urologists (15.28%) took part in the study. Only 22% of urologists regularly used a questionnaire, such as the IIEF-5. When faced with erection problems, 56.5% of them did not carry out systematic cardiology evaluations. More than half of urologists requested fasting glucose, lipid and total testosterone levels. Twenty-seven percent did not carry out additional tests. First line treatment included a phosphodiesterase 5 inhibitor in 81% of cases. Two thirds of urologists (78%) rated themselves as being correctly trained in the area of erectile dysfunction. However, only 49% systematically inquired about erection problems when faced with benign prostatic hyperplasia and 65% thought that erectile dysfunction was not treated optimally. Despite existing recommendations, only half of urologists carry out a cardiac evaluation when a finding of erectile dysfunction is made. One third of urologists do not request additional testing. Greater training, along with the use of an objective diagnostic tool could help urologists to optimise the care they provide for patients suffering from erectile dysfunction, allowing them to keep working within current guidelines. LEVEL OF EVIDENCE: 3.

Abstract
BACKGROUND Peyronie's disease is an inflammatory disorder of the penis, where scar tissue creates a plaque at the level of the albuginea, limits its extension, and leads to a bent and shorter penis during erections. There are no international standards for the evaluation and the treatment of the disease. The aim of this article is to review the current knowledge about the management of Peyronie's disease and to suggest an algorithm to help physicians evaluate and manage this condition. MATERIAL AND METHODS A literature review was conducted through PubMed database following PRISMA guidelines using the Mesh terms: Peyronie, disease, treatment and diagnosis. Results are presented in a descriptive manner. RESULTS Multiple treatment strategies have been proposed, but no conclusive randomized clinical trial is done to assess their efficacies. The oral treatment was shown to be more beneficial in the setting of a multi-modal approach to treat the acute phase. The non-steroidal anti-inflammatories and the potassium para-aminobenzoate are superior to the other molecules of oral therapy for pain management. Local treatment with topical verapamil, iontophoresis and intra-lesional injection of verapamil, interferon alfa-2b and collagenase clostridium histolyticum (CCH) revolutionized the management of the disease by the modification of the plaque size and angulation. Alternative treatments using extra-corporeal shock wave or traction devices are promising. Intra-lesional injection of CCH is the only therapy approved by the Food and Drug Administration for this condition after the stabilization of the disease. The channeling of the plaque before CCH injections is making better results than the initial protocol, concerning angulation improvement. CONCLUSION Multiple therapeutic strategies exist for the management of the Peyronie's disease, but they lack evidence based data. Further randomized clinical trials are needed to evaluate the current practices and to study more efficient treatments.

Abstract
The pesticide risk assessment for earthworms is currently performed using standardized tests, the model species Eisenia fetida, and the analyses of the data obtained are performed with ad hoc statistical tools. We assessed the impact of two fungicides on the entire growth pattern of the earthworm species Aporrectodea caliginosa, which is highly representative of agricultural fields. Individuals of three different ages (from hatching to 56 days old) were exposed to Cuprafor micro® (copper oxychloride) and Swing® Gold (dimoxystrobin and epoxiconazole). Data were analyzed with an energy-based toxicodynamic model coupled with a toxicokinetic model. The copper fungicide caused a drastic growth inhibition once the no effect concentration (NEC), estimated at 65 mg kg-1 of copper, was exceeded. The Swing® Gold negatively affected the growth with NEC values estimated at 0.387 mg kg-1 and 0.128 mg kg-1 for the dimoxystrobin and the epoxiconazole in this fungicide formulation, respectively. The time-profile of the effects on A. caliginosa individuals was fully accounted for by the model, whatever their age of exposure. Furthermore, toxicity data analyses, supported by measurements of fungicide concentrations in earthworm at the end of the experiment, allowed bettering understanding of the mechanisms of action of the fungicides towards earthworm growth.

Abstract
The use of pesticides in agroecosystems can have negative effects on earthworms, which play key roles in soil functioning such as organic matter decomposition. The aim of this study was to assess the effects of two fungicides (Cuprafor micro®, composed of copper oxychloride, and Swing Gold®, composed of epoxiconazole (EPX) and dimoxystrobin (DMX)) on earthworm reproduction by exposing adults and cocoons. First, adult Aporrectodea caliginosa individuals were exposed for 28 days to 3.33, 10 and 30 times the recommended dose (RD) of Cuprafor micro® corresponding to 25.8, 77.5 and 232.5 mg kg-1 dry soil of copper, respectively, and 0.33, 1 and 3 times the RD of Swing Gold® (corresponding to 5.2 × 10-2 mg DMX kg-1 + 1.94 × 10-2 mg EPX kg-1, 1.55 × 10-1 mg DMX kg-1 + 5.81 × 10-2 mg EPX kg-1 and 4.62 × 10-1 mg DMX kg-1 + 1.74 × 10-1 mg EPX kg-1 respectively), in addition to a control soil with no fungicide treatment. Cocoon variables (production, weight, hatching success, hatching time) were monitored. Second, "naïve" cocoons produced by uncontaminated earthworms were exposed to soils contaminated by the same concentrations of the two fungicides, and we assessed hatching success and hatching time. In the first experiment, cocoon production was halved at the highest copper concentration (232.5 mg Cu kg-1 of dry soil) as compared to the control. Cocoons took 5 more days to hatch, and the hatching success decreased by 35% as compared to the control. In the Swing Gold® treatments, cocoon production was reduced by 63% at 3 times the RD, and the hatching success significantly decreased by 16% at the RD. In the second experiment, only the hatching success of cocoons was impacted by Swing Gold® at 3 times the RD (30% less hatching). It is concluded that the cocoon stock in the soil is crucial for the renewal of populations in the field. The most sensitive endpoint was the hatching success of the cocoons produced by exposed adults. This endpoint and the effects observed on the "naïve" cocoons could be taken into account in pesticide risk assessment.

Abstract
Earthworms act synergistically with microorganisms in soils. They are ecosystem engineers involved in soil organic matter degradation and nutrient cycling, leading to the modulation of resource availability for all soil organisms. Using a soil microcosm approach, we aimed to assess the influence of the earthworm Aporrectodea caliginosa on the response of soil microbial activities against two fungicides, i.e., Cuprafor Micro® (copper oxychloride, a metal) and Swing® Gold (epoxiconazole and dimoxystrobin, synthetic organic compounds). The potential nitrification activity (PNA) and soil enzyme activities (glucosidase, phosphatase, arylamidase, and urease) involved in biogeochemical cycling were measured at the end of the incubation period, together with earthworm biomass. Two common indices of the soil biochemistry were used to aggregate the response of the soil microbial functioning: the geometric mean (Gmean) and the Soil Quality Index (SQI). At the end of the experiment, the earthworm biomass was not impacted by the fungicide treatments. Overall, in the earthworm-free soil microcosms, the two fungicides significantly increased several soil enzyme and nitrification activities, leading to a higher GMean index as compared to the non-treated control soils. The microbial activity responses depended on the type of activity (nitrification was the most sensitive one), on the fungicide (Swing® Gold or Cuprafor Micro®), and on the doses. The SQI indices revealed higher effects of both fungicides on the soil microbial activity in the absence of earthworms. The presence of earthworms enhanced all soil microbial activities in both the control and fungicide-contaminated soils. Moreover, the magnitude of the fungicide impact, integrated through the SQI index, was mitigated by the presence of earthworms, conferring a higher stability of microbial functional diversity. Our results highlight the importance of biotic interactions in the response of indicators of soil functioning (i.e., microbial activity) to pesticides.

Abstract
BACKGROUND This study aims to describe the short-term reactogenicity of the AS03-adjuvanted H5N1 vaccine expressed through adverse events (AEs) and quality-adjusted life-day (QALD) scores. The AEs are likely to be short-term and therefore the quality of life (QoL) questionnaire, SF-36v2, was administered daily to record changes over seven days. A more sensitive application of this instrument should allow for a better understanding of short-term tolerability of adjuvanted vaccines. METHODS Participants (N = 50) received a 2-dose vaccination schedule. Solicited (collected daily: days 0 to 7 [post dose 1] and 21 to 28 [post dose 2]) and unsolicited (collected weekly until day 21) AEs were collected via diary cards. The QoL questionnaires were completed daily (days 0-6) and weekly (days 0, 6, 21, 27) after dose one. Questionnaire data were transformed into SF-6D scores to report QALDs. It was hypothesized post-hoc that the QALD and daily AEs scores should correlate if discrete QoL-changes were captured. RESULTS Pain (92%) and muscle ache (66%) were the most commonly reported solicited local and general AEs respectively, neither increased in intensity nor in frequency after dose 2. No safety concerns were identified during the study. A correlation between the daily AEs and QALD scores existed (correlation coefficient, - 0.97 (p < 0.001)). The impact of the AEs scores on the QALD was marginal (- 0.02 max for one day). CONCLUSION Similarly with other H5N1 studies, no safety concern was identified throughout the study. Some time-limited variations in QALD-scores were reported. Our results imply that daily administration of the SF-36v2 captures changes in QALD-scores. TRIAL REGISTRATION ClinicalTrials.gov .

Abstract
The risk assessment of pesticides on soil fauna is an issue to protect agroecosystem sustainability. Enchytraeids are recognized as relevant soil bioindicators of chemical stress in agroecosystems. In laboratory, the reproduction test was found to be sensitive to reveal chemical impacts on enchytraeids. However, it does not allow to assess the impacts on ecological functions in which enchytraeids are involved. The objectives of this study were (i) to explore the feasibility of the bait-lamina test with enchytraeids under laboratory conditions and (ii) to compare its sensitivity with the Enchytraeid Reproduction Test. We exposed individuals of Enchytraeus albidus to two commercial formulations of fungicides widely used in Europe. The EC50 reproduction for the Swing® Gold (50 g L-1 epoxiconazole and 133 g L-1 dimoxystrobin) and the Cuprafor micro® (50% copper oxychloride) were respectively estimated at 1.66 ± 0.93 times the recommended dose and > 496 mg kg-1 of copper. However, no impact was found on the feeding activity of enchytraeids. The bait-lamina test thus appeared less sensitive than the Enchytraeid Reproduction Test to the tested fungicides. Despite that, this test which is achievable under laboratory conditions and allows assessing indirect effects of pesticides is quick, cheap, and easy to perform. It would deserve to be used to explore longer-exposure effects through the repeated addition of bait-lamina sticks.

Abstract
Ecotoxicological tests with earthworms are widely used and are mandatory for the risk assessment of pesticides prior to registration and commercial use. The current model species for standardized tests is Eisenia fetida or Eisenia andrei. However, these species are absent from agricultural soils and often less sensitive to pesticides than other earthworm species found in mineral soils. To move towards a better assessment of pesticide effects on non-target organisms, there is a need to perform a posteriori tests using relevant species. The endogeic species Aporrectodea caliginosa (Savigny, 1826) is representative of cultivated fields in temperate regions and is suggested as a relevant model test species. After providing information on its taxonomy, biology, and ecology, we reviewed current knowledge concerning its sensitivity towards pesticides. Moreover, we highlighted research gaps and promising perspectives. Finally, advice and recommendations are given for the establishment of laboratory cultures and experiments using this soil-dwelling earthworm species.

Abstract
Because of the wide use of pesticides in agriculture, there is still a need of higher-tier field studies to assess ecotoxicological effects of commercial formulations on a wider variety of non-target soil organisms such as soil annelids. We here tested the effects of different concentrations of two fungicide formulations, i.e., Cuprafor Micro® (composed of 500 g kg-1 copper oxychloride) and Swing Gold® (composed of 50 g l-1 epoxiconazole and 133 g l-1 dimoxystrobin) on two families of terrestrial oligochaetes (Lumbricidae and Enchytraeidae) after 1 month of exposure. We also assessed the feeding activity of soil organisms using the bait lamina method. Along with the feeding activity, the enchytraeid density, diversity and communities were not different in the control and the contaminated plots. By contrast, epigeic earthworms were absent and earthworm diversity and densities of anecic species decreased significantly in the plots contaminated at ten times the recommended dose of the Swing Gold® formulation. The copper fungicide (at 0.75 and 7.5 kg Cu ha-1) and the treatment with the pesticide mixture (Cuprafor Micro® at 0.75 kg Cu ha-1 and Swing Gold® at the recommended dose) did not affect Oligochaeta communities compared with the control, except the Shannon index for earthworms in the mixture of both fungicides. Responses of the two annelid families to the tested pesticides were different with higher effects observed on the diversity and the community structure of earthworms compared with enchytraeids. This study allowed detecting early changes on oligochaete populations after pesticide application.

Abstract
The use of pesticides in crop fields may have negative effects on soil Oligochaeta Annelida, i.e., earthworms and enchytraeids, and thus affect soil quality. The aim of this study was to assess the effects of two commercial fungicide formulations on the earthworm Aporrectodea caliginosa and the enchytraeid Enchytraeus albidus in a natural soil. The fungicides were Cuprafor micro® (copper oxychloride), commonly used in organic farming, and Swing Gold® (epoxiconazole and dimoxystrobin), a synthetic fungicide widely used in conventional farming to protect cereal crops. Laboratory experiments were used to assess the survival, biomass loss and avoidance behaviour. No lethal effect was observed following exposure to the copper fungicide for 14 days, even at 5000mgkg-1 of copper, i.e. 650 times the recommended dose (RD). However, a significant decrease in biomass was observed from 50mgkg-1 of copper (6.5 times the RD) for A. caliginosa and at 5000mgkg-1 of copper (650 times the RD) for E. albidus. These sublethal effects suggest that a longer period of exposure would probably have led to lethal effects. The EC50 avoidance for the copper fungicide was estimated to be 51.2mgkg-1 of copper (6.7 times the RD) for A. caliginosa, and 393mgkg-1 of copper (51 times the RD) for E. albidus. For the Swing Gold® fungicide, the estimated LC50 was 7.0 10-3mLkg-1 (6.3 times the RD) for A. caliginosa and 12.7 10-3mLkg-1 (11.0 times the RD) for E. albidus. No effect on biomass or avoidance was observed at sublethal concentrations of this synthetic fungicide. It was concluded that enchytraeids were less sensitive than earthworms to the two commercial fungicides in terms of mortality, biomass loss and avoidance behaviour. Therefore we discuss the different strategies possibly used by the two Oligochaeta species to cope with the presence of the pesticides were discussed, along with the potential consequences on the soil functions.

Abstract
OBJECTIVES Specify urinary functional impairment associated with diabetic pathology. Propose guidance for screening, monitoring of clinical signs of lower urinary tract (LUTS) and describe the specifics of the urological treatment of patients. METHODS A review of literature using PubMed library was performed using the following keywords alone or in combination: "diabetes mellitus", "diabetic cystopathy", "overactive bladder", "bladder dysfunction", "urodynamics", "nocturia". RESULTS LUTS are more common in the diabetic population with an estimated prevalence between 37 and 70 %, and are probably underevaluated in routine practice. They are heterogeneous and are frequently associated with other diabetic complications. Both storage and voiding symptoms can coexist. Despite a major evaluation in the literature, no recommendation supervises the assessment and management of LUTS in this specific population. An annual screening including medical history, bladder and kidney ultrasound and post-void residual measurement is required in the follow-up of diabetic patients. Specific urologial referral and urodynamic investigations will be performed according to the findings of first-line investigations. The type of bladder dysfunction, the risk of urinary tract infections and dysautonomia should be considered in the specific urological management of these patients. CONCLUSION Diabetes mellitus significantly impacts on the lower urinary tract function. A screening of LUTS is required as well as other complications of diabetes. The management of LUTS must take into consideration the specific risks of the diabetic patient regarding the loss of bladder contractility, the possibility of dysautonomia and infectious complications.

Abstract
The surgical care pathway of neurologic patients has two aims: preventing urinary morbidity and mortality and improving their quality of life. It requires taking into account the specificities of disabilities in domains of body functions: circulatory, ventilation and digestive physiology, motor functions, sensory functions, mental functions, and skin fragility which are responsible of dependencies in this heterogeneous group of patients. This management is necessarily multidisciplinary to be optimal and through specific clinical care pathway, providing guidance to the surgical procedure: preparation of the surgery, its realization, and post-operative rehabilitation. The indication for surgery must be coordinated and validated in neuro-urology multidisciplinary staff. Preoperative stay in a physical and rehabilitation medicine center may be useful to ensure a complete assessment and anticipate problems related to surgery. The patient will be hospitalized in the urology department in a single room suited to their disabilities and handicaps. The chronic treatments should be not modified if possible. The lack of sensitivity does not dispense anesthesia to prevent autonomic hyperreflexia, the most severe complication after high complete spinal cord injury. The laparoscopy and sub-peritoneal surgery, the early removal nasogastric tube and early refeeding make it possible to early resumption of intestinal transit. In many cases, the patients should be transferred to a physical and rehabilitation medicine during post-operative period where the nursing care will be most suitable. A quickly adapted rehabilitation must be able to reduce loss of function and physical dependence.

Abstract
UNLABELLED We have analyzed pharmacokinetic data for glycerol phenylbutyrate (also GT4P or HPN-100) and sodium phenylbutyrate with respect to possible dosing biomarkers in patients with urea cycle disorders (UCD). STUDY DESIGN These analyses are based on over 3000 urine and plasma data points from 54 adult and 11 pediatric UCD patients (ages 6-17) who participated in three clinical studies comparing ammonia control and pharmacokinetics during steady state treatment with glycerol phenylbutyrate or sodium phenylbutyrate. All patients received phenylbutyric acid equivalent doses of glycerol phenylbutyrate or sodium phenylbutyrate in a cross over fashion and underwent 24-hour blood samples and urine sampling for phenylbutyric acid, phenylacetic acid and phenylacetylglutamine. RESULTS Patients received phenylbutyric acid equivalent doses of glycerol phenylbutyrate ranging from 1.5 to 31.8 g/day and of sodium phenylbutyrate ranging from 1.3 to 31.7 g/day. Plasma metabolite levels varied widely, with average fluctuation indices ranging from 1979% to 5690% for phenylbutyric acid, 843% to 3931% for phenylacetic acid, and 881% to 1434% for phenylacetylglutamine. Mean percent recovery of phenylbutyric acid as urinary phenylacetylglutamine was 66.4 and 69.0 for pediatric patients and 68.7 and 71.4 for adult patients on glycerol phenylbutyrate and sodium phenylbutyrate, respectively. The correlation with dose was strongest for urinary phenylacetylglutamine excretion, either as morning spot urine (r = 0.730, p < 0.001) or as total 24-hour excretion (r = 0.791 p<0.001), followed by plasma phenylacetylglutamine AUC(24-hour), plasma phenylacetic acid AUC(24-hour) and phenylbutyric acid AUC(24-hour). Plasma phenylacetic acid levels in adult and pediatric patients did not show a consistent relationship with either urinary phenylacetylglutamine or ammonia control. CONCLUSION The findings are collectively consistent with substantial yet variable pre-systemic (1st pass) conversion of phenylbutyric acid to phenylacetic acid and/or phenylacetylglutamine. The variability of blood metabolite levels during the day, their weaker correlation with dose, the need for multiple blood samples to capture trough and peak, and the inconsistency between phenylacetic acid and urinary phenylacetylglutamine as a marker of waste nitrogen scavenging limit the utility of plasma levels for therapeutic monitoring. By contrast, 24-hour urinary phenylacetylglutamine and morning spot urine phenylacetylglutamine correlate strongly with dose and appear to be clinically useful non-invasive biomarkers for compliance and therapeutic monitoring.

Abstract
Multiple sclerosis (MS) is a neurological disease characterized by multiple demyelinating lesions disseminated throughout the central nervous system (nerve conduction block). The management of these patients requires a perfect knowledge of the natural history of the disease. In this article, the authors review the literature to identify the most frequent voiding disorders observed in this disease and then study the diagnostic and therapeutic modalities and the optimal modalities of follow-up in these patients, in view of the risk of various urological complications.

Abstract
Non-continent urinary diversions can be proposed temporarily in neurological patients or at end-stage. They are especially proposed in patients in chronic retention in whom intermittent catheterization cannot be performed for anatomical or practical reasons (severity of neurological handicap). In this study, the authors present the various non-continent urinary diversions reported in the literature, describing the technical modalities of each diversion, their main complications and their short-term, medium-term and long-term results.

Abstract
The Institute of Medicine has described the Electronic Medical Record [EMR] as an essential technology for health care that improves patient safety and the quality of care when compared to traditional paper-based records. [1,2,3] Despite major financial expenditures on health information technology related to EMRs in developed countries such as North America, Britain and Australia, success rates for successful implementations have been low. One specific domain of information management relates to the communication of health care between those involved in the care process. Summarization of patient histories is a core component of EMR systems and assists in the communication of health care. This paper demonstrates how the utilization of simple technologies, can lead to the successful implementation of the Summary Patient Record [SPR] component of an EMR system.
