Child education and work choices in the presence of a conditional cash transfer programme in rural Colombia

This research is part of a large evaluation effort, undertaken by a consortium formed by IFS, Econometria and SEI, which has considered the effects of Familias en Accion on a variety of outcomes one year after its implementation. In early reports, we focussed on the effects of the programme on school enrolment. In this paper, we both expand those results, by carefully analysing anticipation effects along with other issues, and complement them with an analysis of child labour - both paid and unpaid (including domestic) work. The child labour analysis is made possible due to a rich time use module of the surveys that has not previously been analysed. We find that the programme increased the school participation rates of 14 to 17 year old children quite substantially, by between 5 and 7 percentage points, and had lower, but non-negligible effects on the enrolment of younger children of between 1.4 and 2.4 percentage points. In terms of work, the effects are generally largest for younger children whose participation in domestic work decreased by around 10 to 12 percentage points after the programme but whose participation in income-generating work remained largely unaffected by the programme. We also find evidence of school and work time not being fully substitutable, suggesting that some, but not all, of the increased time at school may be drawn from children's leisure time

La préservation du patrimoine naturel littoral dans le processus de la gestion intégrée des zones côtières : éléments de réflexion pour l'élaboration d'un projet et perspectives

The coastal zone is an area of conflicting processes reflecting its position at the interface between the terrestrial and marine environments. This area needs further study and an enforcement of co-ordinated conservation policy for the implementation of effective protection. A multidisciplinary team (law, ecology, biology, and geography) has published a book, which assembles the elements of current politics involved with the preservation of the natural heritage of the coasts of mainland France. Part 1 deals on the definition of the coastal zone, the dispositions for the preservation of the natural heritage, the institutions concerned with its knowledge about and management and the objective criteria and methods for the choice or separation of zones to be protected. Part 2 gives the characteristic heritage aspects of the three coastal chosen regions. Part 3 gives perspectives to set up a more management model for the preservation of the natural heritage. It is necessary to have a clarification of current expertise resulting in a harmonization and institutional co-ordination of organisms linked to the coastal zone. The reform of the status of the CELRL increases its intervention in the maritime public domain. It offers prospects to consolidate this organization in its role in the protection of the littoral natural patrimonyInterface entre le milieu terrestre et le milieu marin, le littoral est une zone conflictuelle où les usages sont contradictoires, et un espace où il existe des besoins de connaissances et où il faut mettre en place une politique coordonnée de protection. Un ouvrage vient d'être réalisé par une équipe pluridisciplinaire (droit, écologie, biologie, géographie) en réponse au programme LITEAU du MATE. Il recense les éléments de la politique de préservation du patrimoine naturel de la France métropolitaine. Il prend pour exemples trois littoraux. Le Temps 1 s'ordonne autour des définitions du littoral, des institutions impliquées dans sa connaissance et sa gestion, des critères et méthodes objectives pour choisir ou délimiter des zones à préserver. Le Temps 2 traite des particularités patrimoniales des trois régions choisies. Le Temps 3 donne des perspectives pour construire un modèle de gestion satisfaisant du patrimoine naturel littoral à partir de l'analyse de l'existant. Les nombreuses interactions entre les intervenants multiples sur le littoral imposent une clarification des compétences, une harmonisation et une coordination institutionnelle. La réforme du statut du CELRL prévoit son intervention au domaine public maritime ; elle offre des perspectives pour le conforter dans son rôle d'acteur de la protection du patrimoine naturel littoral

Rattling Europe’s ordoliberal ‘iron cage’ : the contestation of austerity in Southern Europe

This article explains the popular revolt against austerity in Southern Europe as the outcome of profound politico-economic changes that are shaped by the transformation of the European Union’s (EU’s) macro-economic governance. It comprises three parts. The first part demonstrates how ordoliberalism – the Germanic variant of (neo)liberal economic thinking – was embedded in the EU’s new macro-economic governance, in processes that constitutionalise austerity and remove democratic controls over the economy. The second part examines the impact of austerity-driven reforms on welfare and employment in the aftermath of the sovereign debt crisis. These reforms undermined the social reproduction of Southern Europe’s familistic welfare model by destabilising three key pillars of social protection: employment security for households’ primary earners; small property ownership; and pension adequacy. The third part analyses the emergence of anti-austerity social politics in Southern Europe, both parliamentary and grassroots, and assesses their effectiveness in light of the collapse of public trust in both EU and domestic political institutions. The article concludes with our reflections on the fragility of EU’s integration process under the hegemony of ordoliberalism

Active surveillance in renal transplant patients with prostate cancer: a multicentre analysis

Introduction: Due to medical improvements leading to increased life expectancy after renal transplantation and widened eligibility criteria allowing older patients to be transplanted, incidence of (low-risk) prostate cancer (PCa) is increasing among renal transplant recipients (RTR). It remains to be established whether active surveillance (AS) for PCa represents a safe treatment option in this setting. Therefore, we aim to compare AS discontinuation and oncological outcomes of AS for PCa of RTR vs. non-transplant patients. Methods: Multicentre study including RTR diagnosed with PCa between 2008 and 2018 in whom AS was initiated. A subgroup of non-RTR from the St. Antonius hospital AS cohort was used as a control group. Comparison of RTR vs. non-RTR was performed by 2:1 propensity score matched survival analysis. Outcome measures included tumour progression-free survival, treatment-free survival, metastasis rates, biochemical recurrence rates and overall survival. Patients were matched based on age, year of diagnosis, PSA, biopsy ISUP grade group, relative number of positive biopsy cores and clinical stage. Results: A total of 628 patients under AS were evaluated, including 17 RTRs and 611 non-RTRs. A total of 13 RTR cases were matched with 24 non-RTR cases. Median overall follow-up for the RTR and non-RTR matched cases was, respectively, 5.1 (IQR 3.2–8.7) years and 5.7 (IQR 4.8–8.1) years. There were no events of metastasis and biochemical recurrence among matched cases. The matched-pair analysis results in a 1-year and 5-year survival of the RTR and non-RTR patients were, respectively, 100 vs. 92%, and 39 vs. 76% for tumour progression, 100 vs. 91% and 59 vs. 76% for treatment-free survival and, respectively, 100 vs. 100% and 88 vs. 100% for overall survival. No significant differences in tumour progression-free survival (p = 0.07) and treatment-free survival were observed (p = 0.3). However, there was a significant difference in overall survival comparing both groups (p = 0.046). Conclusions: AS may be carefully considered in RTR with low-risk PCa. In our preliminary analysis, no major differences were present in AS outcomes between RTR and non-RTR. Overall mortality was significantly higher in the RTR subgroup

Migration outflows and optimal migration policy: rules versus discretion

We study the effects of more open borders on return migration and show that migrants are more likely to return to the origin country when migration rules are softened, because this implies that they could more easily re-migrate if return migration is unsuccessful. As a result, softening migration rules leads to lower net inflows than is generally acknowledged. We show that if government follows rules to shape the optimal migration policy, it will choose more open “borders” than were its behaviour to be discretionary. However, this requires an appropriate commitment technology. We show that electoral accountability may be a solution to the commitment problem. As a matter of fact, observed softer immigration rules in western countries suggest the effectiveness of such a mechanism.info:eu-repo/semantics/publishedVersio

Race-free estimated glomerular filtration rate equation in kidney transplant recipients:development and validation study

OBJECTIVE: To compare the performance of a newly developed race-free kidney recipient specific glomerular filtration rate (GFR) equation with the three current main equations for measuring GFR in kidney transplant recipients.DESIGN: Development and validation study SETTING: 17 cohorts in Europe, the United States, and Australia (14 transplant centres, three clinical trials).PARTICIPANTS: 15 489 adults (3622 in development cohort (Necker, Saint Louis, and Toulouse hospitals, France), 11 867 in multiple external validation cohorts) who received kidney transplants between 1 January 2000 and 1 January 2021.MAIN OUTCOME MEASURE: The main outcome measure was GFR, measured according to local practice. Performance of the GFR equations was assessed using P 30 (proportion of estimated GFR (eGFR) within 30% of measured GFR (mGFR)) and correct classification (agreement between eGFR and mGFR according to GFR stages). The race-free equation, based on creatinine level, age, and sex, was developed using additive and multiplicative linear regressions, and its performance was compared with the three current main GFR equations: Modification of Diet in Renal Disease (MDRD) equation, Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) 2009 equation, and race-free CKD-EPI 2021 equation. RESULTS: The study included 15 489 participants, with 50 464 mGFR and eGFR values. The mean GFR was 53.18 mL/min/1.73m 2 (SD 17.23) in the development cohort and 55.90 mL/min/1.73m 2 (19.69) in the external validation cohorts. Among the current GFR equations, the race-free CKD-EPI 2021 equation showed the lowest performance compared with the MDRD and CKD-EPI 2009 equations. When race was included in the kidney recipient specific GFR equation, performance did not increase. The race-free kidney recipient specific GFR equation showed significantly improved performance compared with the race-free CKD-EPI 2021 equation and performed well in the external validation cohorts (P 30 ranging from 73.0% to 91.3%). The race-free kidney recipient specific GFR equation performed well in several subpopulations of kidney transplant recipients stratified by race (P 30 73.0-91.3%), sex (72.7-91.4%), age (70.3-92.0%), body mass index (64.5-100%), donor type (58.5-92.9%), donor age (68.3-94.3%), treatment (78.5-85.2%), creatinine level (72.8-91.3%), GFR measurement method (73.0-91.3%), and timing of GFR measurement post-transplant (72.9-95.5%). An online application was developed that estimates GFR based on recipient's creatinine level, age, and sex (https://transplant-prediction-system.shinyapps.io/eGFR_equation_KTX/). CONCLUSION: A new race-free kidney recipient specific GFR equation was developed and validated using multiple, large, international cohorts of kidney transplant recipients. The equation showed high accuracy and outperformed the race-free CKD-EPI 2021 equation that was developed in individuals with native kidneys.TRIAL REGISTRATION: ClinicalTrials.gov NCT05229939.</p

Spontaneous focal activation of invariant natural killer T (iNKT) cells in mouse liver and kidney

<p>Abstract</p> <p>Background</p> <p>Invariant natural killer T (iNKT) cells differ from other T cells by their hyperactive effector T-cell status, in addition to the expression of NK lineage receptors and semi-invariant T-cell receptors. It is generally agreed that the immune phenotype of iNKT cells is maintained by repeated activation in peripheral tissues although no explicit evidence for such iNKT cell activity <it>in vivo </it>has so far been reported.</p> <p>Results</p> <p>We used an interferon (IFN)-γ-inducible cytoplasmic protein, Irga6, as a histological marker for local IFN-γ production. Irga6 was intensely expressed in small foci of liver parenchymal cells and kidney tubular epithelium. Focal Irga6 expression was unaffected by germ-free status or loss of TLR signalling and was totally dependent on IFN-γ secreted by T cells in the centres of expression foci. These were shown to be iNKT cells by diagnostic T cell receptor usage and their activity was lost in both CD1 d and Jα-deficient mice.</p> <p>Conclusions</p> <p>This is the first report that supplies direct evidence for explicit activation events of NKT cells <it>in vivo </it>and raises issues about the triggering mechanism and consequences for immune functions in liver and kidney.</p
