Sustainability limits needed for CO2 removal

International audienceMany governments and industries are relying on future large-scale, land-based carbon dioxide (CO2) removal (CDR) to avoid making necessary steep greenhouse gas (GHG) emission cuts today (1, 2). Not only does this risk locking us into a high overshoot above 1.5°C (3), but it will also increase biodiversity loss, imperiling the Kunming-Montreal Global Biodiversity Framework (KMGBF) goals (4). Such CDR deployments also pose major economic, technological, and social feasibility challenges; threaten food security and human rights; and risk overstepping multiple planetary boundaries, with potentially irreversible consequences (1, 5, 6). We propose three ways to build on the Intergovernmental Panel on Climate Change (IPCC) analyses of CDR mitigation potential by assessing sustainability risks associated with land-use change and biodiversity loss: estimate the sustainable CDR budget based on socioecological thresholds; identify viable mitigation pathways that do not overstep these thresholds; and reframe governance around allocating limited CDR supply to the most legitimate uses

Language transmission in France in the course of the 20th century

“French shall be the only language of education”, proclaimed the Ministerial Order of 7 June 1880 laying down the model primary school regulations. “The language of the Republic is French”, recently added article 2 of the Constitution (1992). But do families follow the strictures of state education and institutions? What were the real linguistic practices of the population of France in the last century? Sandwiched between the monopoly of the national language and the spread of English, what has become of French regional dialects, and what is happening to the languages introduced by immigration

La dynamique des langues en France au fil du XXe siècle

« Le français sera seul en usage dans l’école », stipulait l’arrêté ministériel du 7 juin 1880 fixant le règlement-modèle des écoles primaires. « La langue de la République est le français », renchérit depuis peu l’article 2 de la Constitution (1992). Mais ce qui vaut pour l’École et les institutions officielles s’observe-t-il aussi au sein des familles ? Quelles ont été au cours du siècle écoulé les pratiques linguistiques réelles des habitants de la France ? Entre le monopole de la langue nationale et l’essor de l’anglais, que sont devenus les parlers de nos régions, que deviennent les langues introduites par l’immigration

Contrast-enhanced coded phase-inversion harmonic sonography of knee synovitis correlates with histological vessel density: 2 automated digital quantifications

OBJECTIVE: To use contrast-enhanced coded phase-inversion harmonic B-mode sonography to assess the acoustic enhancement of the synovial area of the knee; and to compare the data with the histological vessel density. METHODS: Eleven patients eligible for a knee arthroscopy were studied. Acoustic quantification was carried out by a digital image analysis program that detects the time-dependent increase [intensity (time) = k x time + C] of gray-level intensity in all the pixels of a specific region of interest (ROI) following intravenous injection of the microbubble contrast agent sulfur hexafluoride. Echo-guided synovial biopsies were carried out in the same ROI. Synovial vessel areas were quantified after Factor VIII immunostaining of synovial biopsies using an automated digital image analysis. RESULTS: Significant (p 0.01 (r = 0.93) and k(max) values (r = 0.79), as well as between the 2 latter parameters (r = 0.72). The histological vessel density and the 2 acoustic parameters were also significantly correlated with the logarithm of erythrocyte sedimentation rate (r = 0.77, r = 0.87, r = 0.67, respectively) and with log C-reactive protein serum concentration (r = 0.69, r = 0.83, r = 0.62, respectively). CONCLUSION: Contrast-enhanced coded phase-inversion harmonic B-mode sonography coupled with an appropriate data analysis method is a new tool to identify and quantify vessel density in knee synovitis

Protecting the child while preserving the relationship: Using baby’s relational withdrawal to gauge the effect of parental visitation

<div><p>The impact of children’s interactions with parents in the context of out-of-home placements is receiving much-needed cross-disciplinary attention. However, the paucity of instruments that can reliably represent young children’s experiences of such interactions precludes a nuanced evaluation of their impact on wellbeing and development. In response to this empirical gap, the present study investigates children’s relational withdrawal as a clinically salient, easily observable and conceptually valid measure of infants’ and toddlers’ responses to parents. Relational withdrawal, challenging behaviors and salivary cortisol were assessed before, during and after parental visits. Conceptually, the findings suggest that observations of relational withdrawal correlate meaningfully with measure of neurobiological reactivity. Clinically, three profiles of cross-variable responses in children appeared, distinguishing between groups that experience increased, decreased or unchanged levels of stress in response to parental visits. Taken together, the findings lend empirical support to systematic observations of relational withdrawal to bolster evaluations of young children’s experience of parental visitation during out-of-home placements.</p></div

What are the prognostic factors for the development of incontinence-associated dermatitis (IAD) : a protocol for a systematic review and meta-analysis

Introduction Incontinence-associated dermatitis (IAD) is irritant contact dermatitis and skin damage associated with prolonged skin contact with urine and/or faeces. Identifying prognostic factors for the development of IAD may improve management, facilitate prevention and inform future research. Methods and analysis This protocol follows the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Prospective and retrospective observational studies or clinical trials in which prognostic factors associated with the development of IAD are described are eligible. There are no restrictions on study setting, time, language, participant characteristics or geographical regions. Reviews, editorials, commentaries, methodological articles, letters to the editor, cross-sectional and case-control studies, and case reports are excluded. MEDLINE, CINAHL, EMBASE and The Cochrane Library will be searched from inception until May 2023. Two independent reviewers will independently evaluate studies. The Quality in Prognostic Studies tool will be used to assess the risk of bias, and the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies-Prognostic Factors checklist will be used for data extraction of the included studies. Separate analyses will be conducted for each identified prognostic factor, with adjusted and unadjusted estimated measures analysed separately. Evidence will be summarised with a meta-analysis when possible, and narratively otherwise. The Q and I 2 statistics will be calculated in order to quantify heterogeneity. The quality of the evidence obtained will be evaluated according to the Grades of Recommendation Assessment, Development and Evaluation guidance. Ethics and dissemination No ethical approval is needed since all data is already publicly accessible. The results of this work will be published in a peer-reviewed scientific journal.
