Tsiganes : la vie de bohème ?

Depuis maintenant plus de trente ans, le Musée dauphinois explore les multiples identités du territoire sur lequel il est installé. Un cycle d’expositions a ainsi été consacré aux populations locales d’origine étrangère dès les années 1980. Après les Isérois d’origine coratine, grecque, arménienne, maghrébine ou encore italienne, le musée a choisi de s’intéresser aux Roms d’Europe de l’Est qui ont migré ces dernières années dans la région, à la fois pour faire état de la précarité de leurs co..

Lire la Phénoménologie de l'esprit de Hegel

La Phénoménologie de l’esprit, parue en 1807, est un ouvrage singulier par son projet, sa forme, et la variété des sujets qu’il aborde. Il contient des développements célèbres concernant ce qu’on a appelé la « dialectique du maître et de l’esclave », la « conscience malheureuse » et la « belle âme », notamment. Bien que ces thèmes appartiennent à la culture commune et qu’ils se retrouvent aujourd’hui à tous les niveaux de l’enseignement philosophique, de la terminale à l’agrégation, aucun ouvrage collectif n’avait encore été publié en français qui se donne pour tâche de guider la lecture de ce chef-d’œuvre hégélien dans son intégralité. Rédigé par des spécialistes de Hegel, cet ouvrage suit pas à pas le cheminement de la Phénoménologie de l’esprit. Chaque contribution est consacrée à un chapitre ou une partie de chapitre dont elle propose un commentaire synthétique accessible. Par-delà l’objectif premier, aider à découvrir ou approfondir la Phénoménologie de l’esprit, il s’agit de restituer la diversité des appropriations philosophiques dont cette œuvre foisonnante a fait l’objet depuis sa parution et d’inviter les lecteurs et lectrices à en explorer la richesse inépuisable.Published in 1807, Hegel’s Phenomenology of Spirit is highly original in its project, in its form and the variety of its subject-matters. It is famous notably for its “master-slave dialectics”, and the analysis of the “unhappy consciousness” or the “beautiful soul”. These themes have become part of the common culture and they are indeed often mentioned in the teachings at high schools and universities, but a reader of this Hegelian masterpiece is still lacking in French. Written by Hegel scholars, this book proceeds steps by step, reconstructing the various stages of the development of Hegel’s thought in the Phenomenology of Spirit. Each contribution elaborates a synthetic commentary of a chapter or sub-chapter. The main objective is to help the reader understanding these chapters and their interconnections. But what is at stake is also to give a hint of the variety of philosophical discussions that have been triggered by them, and to invite the reader exploring all of its richness

Ablation of Succinate Production from Glucose Metabolism in the Procyclic Trypanosomes Induces Metabolic Switches to the Glycerol 3-Phosphate/Dihydroxyacetone Phosphate Shuttle and to Proline Metabolism*

Trypanosoma brucei is a parasitic protist that undergoes a complex life cycle during transmission from its mammalian host (bloodstream forms) to the midgut of its insect vector (procyclic form). In both parasitic forms, most glycolytic steps take place within specialized peroxisomes, called glycosomes. Here, we studied metabolic adaptations in procyclic trypanosome mutants affected in their maintenance of the glycosomal redox balance. T. brucei can theoretically use three strategies to maintain the glycosomal NAD+/NADH balance as follows: (i) the glycosomal succinic fermentation branch; (ii) the glycerol 3-phosphate (Gly-3-P)/dihydroxyacetone phosphate (DHAP) shuttle that transfers reducing equivalents to the mitochondrion; and (iii) the glycosomal glycerol production pathway. We showed a hierarchy in the use of these glycosomal NADH-consuming pathways by determining metabolic perturbations and adaptations in single and double mutant cell lines using a combination of NMR, ion chromatography-MS/MS, and HPLC approaches. Although functional, the Gly-3-P/DHAP shuttle is primarily used when the preferred succinate fermentation pathway is abolished in the Δpepck knock-out mutant cell line. In the absence of these two pathways (Δpepck/RNAiFAD-GPDH.i mutant), glycerol production is used but with a 16-fold reduced glycolytic flux. In addition, the Δpepck mutant cell line shows a 3.3-fold reduced glycolytic flux compensated by an increase of proline metabolism. The inability of the Δpepck mutant to maintain a high glycolytic flux demonstrates that the Gly-3-P/DHAP shuttle is not adapted to the procyclic trypanosome context. In contrast, this shuttle was shown earlier to be the only way used by the bloodstream forms of T. brucei to sustain their high glycolytic flux

Predictors of treatment response in a lupus nephritis population: lessons from the Aspreva Lupus Management Study (ALMS) trial

Objectives: To identify predictors of overall lupus and lupus nephritis (LN) responses in patients with LN. Methods: Data from the Aspreva Lupus Management Study (ALMS) trial cohort was used to identify baseline predictors of response at 6 months. Endpoints were major clinical response (MCR), improvement, complete renal response (CRR) and partial renal response (PRR). Univariate and multivariate logistic regressions with least absolute shrinkage and selection operator (LASSO) and cross-validation in randomly split samples were utilised. Predictors were ranked by the percentage of times selected by LASSO and prediction performance was assessed by the area under the receiver operating characteristics (AUROC) curve. Results: We studied 370 patients in the ALMS induction trial. Improvement at 6 months was associated with older age (OR=1.03 (95% CI: 1.01 to 1.05) per year), normal haemoglobin (1.85 (1.16 to 2.95) vs low haemoglobin), active lupus (British Isles Lupus Assessment Group A or B) in haematological and mucocutaneous domains (0.61 (0.39 to 0.97) and 0.50 (0.31 to 0.81)), baseline damage (SDI>1 vs =0) (0.38 (0.16 to 0.91)) and 24-hour urine protein (0.63 (0.50 to 0.80)). LN duration 2–4 years (0.43 (0.19 to 0.97) vs <1 year) and 24-hour urine protein (0.63 (0.45 to 0.89)) were negative predictors of CRR. LN duration 2–4 years (0.45 (0.24 to 0.83) vs <1 year) negatively predicted PRR. The AUROCs of models for improvement, CRR and PRR were 0.56, 0.55 and 0.51 respectively. Conclusions: Baseline variables predicted 6-month outcomes in patients with SLE. While the modest performance of models emphasises the need for new biomarkers to advance this field, the factors identified can help identify those patients who may require novel treatment strategies

Predictors of British Isles Lupus Assessment Group-based outcomes in patients with systemic lupus erythematosus: Analysis from the Systemic Lupus International Collaborating Clinics Inception Cohort

BackgroundWe aimed to identify factors associated with a significant reduction in SLE disease activity over 12&nbsp;months assessed by the BILAG Index.MethodsIn an international SLE cohort, we studied patients from their 'inception enrolment' visit. We also defined an 'active disease' cohort of patients who had active disease similar to that needed for enrolment into clinical trials. Outcomes at 12&nbsp;months were; Major Clinical Response (MCR: reduction to classic BILAG C in all domains, steroid dose of ≤7.5&nbsp;mg and SLEDAI ≤ 4) and 'Improvement' (reduction to ≤1B score in previously active organs; no new BILAG A/B; stable or reduced steroid dose; no increase in SLEDAI). Univariate and multivariate logistic regression with Least Absolute Shrinkage and Selection Operator (LASSO) and cross-validation in randomly split samples were used to build prediction models.Results'Inception enrolment' (n = 1492) and 'active disease' (n = 924) patients were studied. Models for MCR performed well (ROC AUC = .777 and .732 in the inception enrolment and active disease cohorts, respectively). Models for Improvement performed poorly (ROC AUC = .574 in the active disease cohort). MCR in both cohorts was associated with anti-malarial use and inversely associated with active disease at baseline (BILAG or SLEDAI) scores, BILAG haematological A/B scores, higher steroid dose and immunosuppressive use.ConclusionBaseline predictors of response in SLE can help identify patients in clinic who are less likely to respond to standard therapy. They are also important as stratification factors when designing clinical trials in order to better standardize overall usual care response rates

More is not always better: The impact of value co‐creation fit on B2B and B2C customer satisfaction

Organizations increasingly rely on customer involvement in the value creation process (i.e., co-creation) to enhance customer satisfaction and differentiate themselves from competitors. While past research has largely indicated that more co-creation is beneficial, some have suggested yet not empirically validated that excess co-creation may negatively impact customers. Applying the service-dominant logic, two studies (B2B and B2C customers) offer insight into the appropriate levels of the co-production and value-in-use dimensions of co-creation. For both B2B and B2C customers, polynomial regression and surface plot analyses indicate an inverted U-shaped relationship between value co-creation and satisfaction, establishing that more co-creation is beneficial only up to a point. As such, we inform managers of factors that can cause the relationship between co-creation and satisfaction to peak and then turn negative. Further, customer expertise and process enjoyment moderate this relationship for B2C (but not B2B) customers, thereby offering ways to mitigate the negative effects of excess co-creation for end-customers. The studies also highlight the importance of value co-creation “fit” between the customer\u27s expected and experienced levels of co-creation. Interestingly, positive misfit (i.e., excess co-creation) retains a stronger negative influence on customer satisfaction than negative misfit (i.e., insufficient co-creation) for both B2B and B2C customers

Post-anaesthesia pulmonary complications after use of muscle relaxants (POPULAR): a multicentre, prospective observational study

Background Results from retrospective studies suggest that use of neuromuscular blocking agents during general anaesthesia might be linked to postoperative pulmonary complications. We therefore aimed to assess whether the use of neuromuscular blocking agents is associated with postoperative pulmonary complications. Methods We did a multicentre, prospective observational cohort study. Patients were recruited from 211 hospitals in 28 European countries. We included patients (aged ≥18 years) who received general anaesthesia for any in-hospital procedure except cardiac surgery. Patient characteristics, surgical and anaesthetic details, and chart review at discharge were prospectively collected over 2 weeks. Additionally, each patient underwent postoperative physical examination within 3 days of surgery to check for adverse pulmonary events. The study outcome was the incidence of postoperative pulmonary complications from the end of surgery up to postoperative day 28. Logistic regression analyses were adjusted for surgical factors and patients’ preoperative physical status, providing adjusted odds ratios (ORadj) and adjusted absolute risk reduction (ARRadj). This study is registered with ClinicalTrials.gov, number NCT01865513. Findings Between June 16, 2014, and April 29, 2015, data from 22803 patients were collected. The use of neuromuscular blocking agents was associated with an increased incidence of postoperative pulmonary complications in patients who had undergone general anaesthesia (1658 [7·6%] of 21694); ORadj 1·86, 95% CI 1·53–2·26; ARRadj –4·4%, 95% CI –5·5 to –3·2). Only 2·3% of high-risk surgical patients and those with adverse respiratory profiles were anaesthetised without neuromuscular blocking agents. The use of neuromuscular monitoring (ORadj 1·31, 95% CI 1·15–1·49; ARRadj –2·6%, 95% CI –3·9 to –1·4) and the administration of reversal agents (1·23, 1·07–1·41; –1·9%, –3·2 to –0·7) were not associated with a decreased risk of postoperative pulmonary complications. Neither the choice of sugammadex instead of neostigmine for reversal (ORadj 1·03, 95% CI 0·85–1·25; ARRadj –0·3%, 95% CI –2·4 to 1·5) nor extubation at a train-of-four ratio of 0·9 or more (1·03, 0·82–1·31; –0·4%, –3·5 to 2·2) was associated with better pulmonary outcomes. Interpretation We showed that the use of neuromuscular blocking drugs in general anaesthesia is associated with an increased risk of postoperative pulmonary complications. Anaesthetists must balance the potential benefits of neuromuscular blockade against the increased risk of postoperative pulmonary complications
