Une approche d’intervention axée sur les femmes peut-elle appeler à la fois une analyse féministe et de développement des communautés ? Une réflexion à partir d’un récit de stage : le Red de Salud de Collique, au Pérou

À partir d’un récit de stage réalisé au Pérou, nous nous questionnons à savoir si les expériences d’intervention réalisées au Red de Salud de Collique, une approche d’intervention axée sur les femmes, appellent à la fois une analyse féministe et de développement des communautés (DC). Cette réflexion nous apparaît importante dans la perspective du défi de taille que pose l’arrimage des pratiques d’intervention sociale aux particularités de communautés dans lesquelles elles s’implantent.From an internship story produced in Peru, we are asking if the intervention experience Red de Salud from Collique (an intervention approach centrered around women) deals with both a feminist and community development (CD) analysis. This reflection appears to be important from a perspective where the main challenge is the link between social intervention practices and the characteristics of the communities in which they are being established

La médiation partenariale en contexte intersectoriel : intervention sociale en émergence, codéveloppement professionnel et recherche

En Amérique du Nord comme en Europe, les enfants, les jeunes et les familles sont au cœur des priorités gouvernementales. Au Québec, la mise en place de coordonnatrices et de coordonnateurs d’Équipes d’Intervention Jeunesse (ÉIJ) contribue à l’émergence d’une nouvelle pratique sociale : la médiation partenariale intersectorielle. Dotés d’un mandat régional, ces coordonnateurs soutiennent les établissements de divers secteurs d’activités tels que la santé, les services sociaux ou l’éducation, pour résoudre diverses impasses cliniques, administratives ou partenariales qui entravent la coordination et la mise en œuvre des services auprès des jeunes et des familles vivant des problèmes multiples. Cet article traite d’une expérience québécoise de codéveloppement professionnel menée avec un groupe de coordonnateurs d’équipes d’intervention jeunesse. L’analyse d’un cas concret de partenariat relatif à une problématique familiale spécifique permet, à titre d’exemple, d’illustrer la pratique de médiation de ces professionnels ainsi que leur démarche de formation continue. L’expérience vécue dans ce contexte débouche actuellement sur un projet de recherche mobilisateur. Celui-ci a pour objectif de modéliser cette nouvelle pratique de médiation dans le champ de l’intervention sociale auprès des jeunes vivant des problèmes multiples.Mediation in context of intersector-based partnership : new social practice, professionnal, codeveloppement and research. In North America, as well as in Europe, the children, the youth and the family are central in government’s priorities. In Quebec, the implementation of youth intervention team’s coordinators contributes to the emergence of a new social practice : intersector-based mediation. Endowed with a regional mandate, the coordinators support organisations from diverse sectors such as health, social services or education so that they partner to resolve diverse issues. Clinical, administrative or collaborative concerns can hinder the coordination and implementation of services to young people and their families. This article relates to a case study of a specific partnership problem that was discussed among a team of Quebec coordinators involved in a professional codevelopment process. It illustrates the approach of an in-service training group that they formed to define and develop their new social practice. The experiment lived in this context opens the way for a research project that will model this new practice of intersector-based mediation in the field of intervention with teenagers and childrens living multiple problems.La mediación asociativa en el contexto intersectorial : surgimiento de la intervención social, desarrollo profesional conjunto e investigación. Tanto en Norteamérica como en Europa, los niños, los jóvenes y las familias se encuentran  en el seno de las prioridades gubernamentales. En Quebec, la asignación de coordinadores y coordinadoras de Equipos de Intervención para la Juventud contribuye al surgimiento de una nueva práctica social: la mediación asociativa intersectorial. Estos coordinadores cuentan con un mandato regional, y ayudan en diversos sectores de actividad, tales como la salud, los servicios sociales o la educación, a resolver diversos problemas clínicos, administrativos o asociativos que obstaculizan la coordinación y la implementación de los servicios para jóvenes y familias con problemáticas múltiples. Este artículo describe una experiencia quebequense de desarrollo profesional conjunto llevado a cabo con un grupo de coordinadores de quipos de intervención para la juventud. El análisis de un caso concreto de asociación relativo a una problemática familiar específica permite, a modo de ejemplo, ilustrar la práctica de la mediación de estos profesionales así como su proceso de formación continua. La experiencia vivida en este contexto se ha plasmado en un proyecto de investigación movilizador que tiene como objetivo usar esta nueva práctica de mediación como modelo en el ámbito de la intervención social para jóvenes con múltiples problemáticas

La nécropole protohistorique du Grand Bassin II à Mailhac, Aude (VIe-Ve s. av. n. è.)

Fouillée au milieu du XXe siècle dans le cadre de sauvetages en milieu rural, la nécropole protohistorique éponyme du Grand Bassin‑II a livré 57 tombes et un bûcher funéraire datés entre le deuxième quart du VIe s. et le début du Ve s. av. n. è. L'étude du mobilier, de son mode de dépôt, de ses associations, mais aussi l'étude anthropologique et l'analyse de l'architecture, confirment ce qui avait été précédemment observé sur d'autres nécropoles contemporaines, en particulier l'évolution des pratiques funéraires à la fin du premier âge du Fer.Grand Bassin II was excavated during the mid twentieth century as part of a rural rescue excavation. The site produced 57 tombs and a funeral pyre dated to between the second quarter of VIth and beginning of Vth centuries BC. The study of the material culture, its mode of deposition and its associations, along with a physical anthropological analysis and a study of the architecture, confirms a series of trends identified on other contemporary necropoli, especially those relating to the development of funerary rites et the end of the early Iron Age

LILAC pilot study : effects of metformin on mTOR activation and HIV reservoir persistence during antiretroviral therapy

Background: Chronic inflammation and residual HIV transcription persist in people living with HIV (PLWH) receiving antiretroviral therapy (ART), thus increasing the risk of developing non-AIDS co-morbidities. The mechanistic target of rapamycin (mTOR) is a key regulator of cellular metabolism and HIV transcription, and therefore represents an interesting novel therapeutic target. Methods: The LILAC pilot clinical trial, performed on non-diabetic ART-treated PLWH with CD4+ /CD8+ T-cell ratios <0.8, evaluated the effects of metformin (12 weeks oral administration; 500-850 mg twice daily), an indirect mTOR inhibitor, on the dynamics of immunological/virological markers and changes in mTOR activation/phosphorylation in blood collected at Baseline, Week 12, and 12 weeks after metformin discontinuation (Week 24) and sigmoid colon biopsies (SCB) collected at Baseline and Week 12. Findings: CD4+ T-cell counts, CD4+ /CD8+ T-cell ratios, plasma markers of inflammation/gut damage, as well as levels of cell-associated integrated HIV-DNA and HIV-RNA, and transcriptionally-inducible HIV reservoirs, underwent minor variations in the blood in response to metformin. The highest levels of mTOR activation/ phosphorylation were observed in SCB at Baseline. Consistently, metformin significantly decreased CD4+ Tcell infiltration in the colon, as well as mTOR activation/phosphorylation, especially in CD4+ T-cells expressing the Th17 marker CCR6. Also, metformin decreased the HIV-RNA/HIV-DNA ratios, a surrogate marker of viral transcription, in colon-infiltrating CD4+ T-cells of 8/13 participants

Structural and functional analysis of the Rous Sarcoma virus negative regulator of splicing and demonstration of its activation by the 9G8 SR protein

Retroviruses require both spliced and unspliced RNAs for replication. Accumulation of Rous Sarcoma virus (RSV) unspliced RNA depends upon the negative regulator of splicing (NRS). Its 5′-part is considered as an ESE binding SR proteins. Its 3′-part contains a decoy 5′-splice site (ss), which inhibits splicing at the bona fide 5′-ss. Only the 3D structure of a small NRS fragment had been experimentally studied. Here, by chemical and enzymatic probing, we determine the 2D structure of the entire RSV NRS. Structural analysis of other avian NRSs and comparison with all sequenced avian NRSs is in favour of a phylogenetic conservation of the NRS 2D structure. By combination of approaches: (i) in vitro and in cellulo splicing assays, (ii) footprinting assays and (iii) purification and analysis of reconstituted RNP complex, we define a small NRS element retaining splicing inhibitory property. We also demonstrate the capability of the SR protein 9G8 to increase NRS activity in vitro and in cellulo. Altogether these data bring new insights on how NRS fine tune splicing activity

Common non-synonymous SNPs associated with breast cancer susceptibility: findings from the Breast Cancer Association Consortium.

Candidate variant association studies have been largely unsuccessful in identifying common breast cancer susceptibility variants, although most studies have been underpowered to detect associations of a realistic magnitude. We assessed 41 common non-synonymous single-nucleotide polymorphisms (nsSNPs) for which evidence of association with breast cancer risk had been previously reported. Case-control data were combined from 38 studies of white European women (46 450 cases and 42 600 controls) and analyzed using unconditional logistic regression. Strong evidence of association was observed for three nsSNPs: ATXN7-K264R at 3p21 [rs1053338, per allele OR = 1.07, 95% confidence interval (CI) = 1.04-1.10, P = 2.9 × 10(-6)], AKAP9-M463I at 7q21 (rs6964587, OR = 1.05, 95% CI = 1.03-1.07, P = 1.7 × 10(-6)) and NEK10-L513S at 3p24 (rs10510592, OR = 1.10, 95% CI = 1.07-1.12, P = 5.1 × 10(-17)). The first two associations reached genome-wide statistical significance in a combined analysis of available data, including independent data from nine genome-wide association studies (GWASs): for ATXN7-K264R, OR = 1.07 (95% CI = 1.05-1.10, P = 1.0 × 10(-8)); for AKAP9-M463I, OR = 1.05 (95% CI = 1.04-1.07, P = 2.0 × 10(-10)). Further analysis of other common variants in these two regions suggested that intronic SNPs nearby are more strongly associated with disease risk. We have thus identified a novel susceptibility locus at 3p21, and confirmed previous suggestive evidence that rs6964587 at 7q21 is associated with risk. The third locus, rs10510592, is located in an established breast cancer susceptibility region; the association was substantially attenuated after adjustment for the known GWAS hit. Thus, each of the associated nsSNPs is likely to be a marker for another, non-coding, variant causally related to breast cancer risk. Further fine-mapping and functional studies are required to identify the underlying risk-modifying variants and the genes through which they act.BCAC is funded by Cancer Research UK (C1287/A10118, C1287/A12014) and by the European Community’s Seventh Framework Programme under grant agreement n8 223175 (HEALTH-F2–2009-223175) (COGS).

Fine-Scale Mapping of the 4q24 Locus Identifies Two Independent Loci Associated with Breast Cancer Risk

Background: A recent association study identified a common variant (rs9790517) at 4q24 to be associated with breast cancer risk. Independent association signals and potential functional variants in this locus have not been explored. Methods: We conducted a fine-mapping analysis in 55,540 breast cancer cases and 51,168 controls from the Breast Cancer Association Consortium. Results: Conditional analyses identified two independent association signals among women of European ancestry, represented by rs9790517 [conditional P = 2.51 × 10−4; OR, 1.04; 95% confidence interval (CI), 1.02–1.07] and rs77928427 (P = 1.86 × 10−4; OR, 1.04; 95% CI, 1.02–1.07). Functional annotation using data from the Encyclopedia of DNA Elements (ENCODE) project revealed two putative functional variants, rs62331150 and rs73838678 in linkage disequilibrium (LD) with rs9790517 (r2 ≥ 0.90) residing in the active promoter or enhancer, respectively, of the nearest gene, TET2. Both variants are located in DNase I hypersensitivity and transcription factor–binding sites. Using data from both The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC), we showed that rs62331150 was associated with level of expression of TET2 in breast normal and tumor tissue. Conclusion: Our study identified two independent association signals at 4q24 in relation to breast cancer risk and suggested that observed association in this locus may be mediated through the regulation of TET2. Impact: Fine-mapping study with large sample size warranted for identification of independent loci for breast cancer risk

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms
