Une européanisation des politiques de conciliation de la vie familiale et professionnelle? : les cas de l'Italie et de la France

Les différents pays membres de l'UE connaissent des politiques dites de « conciliation de la vie professionnelle et familiale » qui correspondent à un ensemble de dispositifs hétéroclites, plus ou moins complexes, mais rarement cohérents. Alliant des objectifs tels que la hausse de la natalité, la protection des mères et des enfants, l'égalité entre femmes et hommes, la lutte contre la pauvreté des enfants et des familles monoparentales et l'activation des femmes, ces politiques sont fortement ancrées dans des traditions nationales de politiques familiales, d'emploi et fiscales. Ces politiques portent en elles l'héritage et les tensions de l'histoire d'un pays. Au moment où un nouvel acteur international, l'Union européenne, intervient de manière de plus en plus explicite dans le débat et dans la définition de ces politiques, la présente étude tend à analyser l'influence exercées par les référentiels européens en matière de politiques de conciliation sur les discours et politiques nationales de l'Italie et de la France. A partir d'une analyse cognitive du processus d'européanisation, nous montrons que les référentiels développés au sein de l'UE, par leur caractère abstrait et flou, n'ont eu jusqu'ici qu'une faible influence sur les discours et politiques en Italie et en France. Croisant une perspective néo-institutionnaliste historique et discursive, notre recherche a été construite autour de deux axes de réflexion. Premièrement, il a été question d'analyser, d'une part, l'évolution du discours tenu par les différentes instances européennes (notamment de la Commission européenne, le Conseil européen et le Fonds Social européen) et, d'autre part, questionner comment un consensus a pu émerger entre des pays et des acteurs qui ont des traditions extrêmement différentes en matière de politique sociale, de politique familiale et de convention de genre. Deuxièmement, il a été question d'analyser si et comment un cadre de référence conçu au niveau communautaire a pu influencer les discours et politiques au niveau national. - The reconciliation of work and family life policies forms, in the EU's member States, a plurality of politics, more or less complex, but rarely coherent. Combining different objectives such as fertility increase, mothers and children protection, equality between men and women, fight against children and lone-parent families poverty and women activation, these policies are part of the national traditions of family, employment and tax policy and bear the heritage and the tensions of the country history. At a moment when a new global player, the European Union, interferes increasingly explicitly in the debate and the definition of reconciling work and family life policies, the question at the heart of this thesis was to define what kind of influence the référentiels of European discourses have on reconciliation policies since the late 1990s, in the Italian and French discourses and policies. Starting from a cognitive analysis of the Europeanization process, we show that the référentiels developed within the EU, by their abstract and vague nature, have had little influence in Italy and France. Crossing an historical and a discursive neo-institutionalist perspective, our research was based on two axes of reasoning. First, we have analysed, on the one hand, the evolution of various European institutions' discoursed (including the European Commission, the European Council and the European Social Fund) and, on the other hand, we have questioned how a consensus has emerged between countries and actors who have very different traditions in social policy, family policy and gender conventions. Secondly, we have observed if and how a framework developed at Community level, as a kind of ideal to strive for, has influenced discourses and policies at the national level.

Wide resection of the lateral malleolus and adjacent tibial, talar and calcanear bones with ankle fusion and allograft reconstruction for an osteosarcoma.

Introduction: Primary bone sarcomas around the ankle are rare. Due to the proximity of neurovascular structures and limited soft tissue reserves, limb salvage is often not possible. Case report: A 19 yo male presented with pain and a progressive swelling of his ankle. X-rays revealed cortical erosions and an extensive periosteal reaction (sunburst) of the distal fibula. MRI showed a large mass of the fibula invading adjacent soft tissue. The lesion appeared close to the ankle joint, but with the articular cartilage as a barrier and without joint effusion. Core-needle biopsy revealed a high-grade chondroblastic osteosarcoma. No metastases were detected. After presentation at our multidisciplinary sarcoma board, the patient was subjected to neo-adjuvant chemotherapy (AOST 03-331). Without any sign of intra-articular contamination of the ankle joint, surgical treatment consisted of wide resection of the lateral malleolus including a large skin patch, the distal third of the fibula, the lateral surfaces of the tibia and talus as well as the insertion of the lateral ligament on the calcaneus. The distal parts of the anterior, peroneal, and posterior muscular compartments were resected en bloc with the tumor. The defect was reconstructed with tibio-talar and talo-calcanear fusion, bony allograft and a plate. Soft-tissue coverage was achieved with a free fascio-cutaneous flap from the controlateral thigh. Histological analysis revealed clear margins and 50% of tumor necrosis. The oncologic treatment was completed with adjuvant chemotherapy. Conclusion: Wide resection and reconstruction of the lateral malleolus is technically demanding but possible in selected cases. Despite some important functional loss, limb salvage is superior to an amputation.

Chemokine receptor trio: CXCR3, CXCR4 and CXCR7 crosstalk via CXCL11 and CXCL12.

Although chemokines are well established to function in immunity and endothelial cell activation and proliferation, a rapidly growing literature suggests that CXC Chemokine receptors CXCR3, CXCR4 and CXCR7 are critical in the development and progression of solid tumors. The effect of these chemokine receptors in tumorigenesis is mediated via interactions with shared ligands I-TAC (CXCL11) and SDF-1 (CXCL12). Over the last decade, CXCR4 has been extensively reported to be overexpressed in most human solid tumors and has earned considerable attention toward elucidating its role in cancer metastasis. To enrich the existing armamentarium of anti-cancerous agents, many inhibitors of CXCL12-CXCR4 axis have emerged as additional or alternative agents for neo-adjuvant treatments and even many of them are in preclinical and clinical stages of their development. However, the discovery of CXCR7 as another receptor for CXCL12 with rather high binding affinity and recent reports about its involvement in cancer progression, has questioned the potential of "selective blockade" of CXCR4 as cancer chemotherapeutics. Interestingly, CXCR7 can also bind another chemokine CXCL11, which is an established ligand for CXCR3. Recent reports have documented that CXCR3 and their ligands are overexpressed in different solid tumors and regulate tumor growth and metastasis. Therefore, it is important to consider the interactions and crosstalk between these three chemokine receptors and their ligand mediated signaling cascades for the development of effective anti-cancer therapies. Emerging evidence also indicates that these receptors are differentially expressed in tumor endothelial cells as well as in cancer stem cells, suggesting their direct role in regulating tumor angiogenesis and metastasis. In this review, we will focus on the signals mediated by this receptor trio via their shared ligands and their role in tumor growth and progression.

La politique régionale : entre compétitivité et respect de l'environnement

Aujourd'hui plus que jamais, le développement économique ne peut se faire au détriment de notre environnement naturel. Dès lors se pose la question de savoir comment parvenir à maintenir la compétitivité d'une économie, tout en tenant compte de l'impact qu'elle a sur révolution du cadre naturel. La présente recherche propose d'investiguer sur la question en se penchant sur les politiques publiques de promotion économique, et plus spécifiquement sur la politique régionale. Faut-il maintenir la confiance dans les courants néoclassiques, comme le laisse supposer la situation actuelle, renforcer la position d'une économie s'inscrivant au sein d'un cadre socio-environnemental ou encore repenser notre mode de fonctionnement économique quant à son développement ? Dans le cas présent, la politique régionale suisse est évaluée à la lumière de trois stratégies de développement économique. D'une part, il y a l'économie fondée sur la connaissance. Cette dernière est à la base de la philosophie actuelle en matière de politique régionale. Ensuite, il y a l'écologie industrielle, qui pour sa part fait la promesse d'un développement économique éco-compatible. Enfin, la troisième stratégie est celle de l'économie de fonctionnalité, qui propose de maximiser l'efficience d'une unité de matière première en limitant notamment la notion de propriété. Au travers d'une grille d'analyse construite sur le modèle des géographies de la grandeur, les trois stratégies sont confrontées aux objectifs de la nouvelle politique régionale suisse (NPR) ainsi qu'à ses modalités de mise en oeuvre. Il en ressort qu'en l'état actuel, la stratégie misant sur l'économie de la connaissance est la plus à même de relever le défi d'un développement économique durable. Toutefois, moyennant adaptations, les autres stratégies pourraient également se révéler être pertinentes. On constate notamment que les éléments clés sont ici l'innovation, ainsi que les dimensions spatiale et temporelle des stratégies. Nous recommandons dès lors d'adopter une approche territorialisée du développement économique, selon une logique de projet au sens de Boltanski & Chiapello. A notre sens, seules les propositions à même de fédérer les acteurs et disposant d'une vision intégrée du développement ont une chance de permettre un développement économique en harmonie avec notre cadre environnemental. - Today more than ever, economic development can't go ahead without consideration for our natural environment. This lays us with the question of how to maintain the competitiveness of an economy, and at the same time to manage the impact of it on the natural frame. This research aims to investigate this question through public policies fostering economy, more specifically through the regional policy. Must one trust the neo-classical way, as the actual situation let's think about it, reinforce the position of an economy within a socio- environmental frame or moreover reinvent our economical modus regarding development? In this case, an assessment of the Swiss regional policy is lead through three strategies of economic development. First, there is the knowledge economy. It is the core concept of the actual philosophy regarding regional policy. Second, there is the industrial ecology which aims to promote an eco-compatible economic development. Last, there is the functional economy, which proposes to maximize the efficiency of every used unit of natural resources by limiting in particular the notion of propriety. Through an analytic frame built on the model of geographies of greatness (géographies de la grandeuή, the three strategies are confronted to the objectives of the Swiss new regional policy (NRP) as well as its implementation. It turns out that actually, the strategy laying on the knowledge economy happens to be the best solution in order to promote a sustainable economic development. Nevertheless, with few adaptations, the other strategies could be pregnant as well. What we can see is that key- elements are here the innovation, as well as the spatial and temporal dimensions of these strategies. We recommend therefore to adopt a territorialised approach of economic development, with a project-based logic as meant by Boltanski & Chiapello. We are convinced that only propositions which are able to unit actors, and with an integrated point of view, have a chance to promote economic development in harmony with our environmental frame.

Stressful life events and neuroticism as predictors of late-life versus early-life depression.

BACKGROUND: The occurrence of depression in younger adults is related to the combination of long-standing factors such as personality traits (neuroticism) and more acute factors such as the subjective impact of stressful life events. Whether an increase in physical illnesses changes these associations in old age depression remains a matter of debate. METHODS: We compared 79 outpatients with major depression and 102 never-depressed controls; subjects included both young (mean age: 35 years) and older (mean age: 70 years) adults. Assessments included the Social Readjustment Rating Scale, NEO Personality Inventory and Cumulative Illness Rating Scale. Logistic regression models analyzed the association between depression and subjective impact of stressful life events while controlling for neuroticism and physical illness. RESULTS: Patients and controls experienced the same number of stressful life events in the past 12 months. However, in contrast to the controls, patients associated the events with a subjective negative emotional impact. Negative stress impact and levels of neuroticism, but not physical illness, significantly predicted depression in young age. In old age, negative stress impact was weakly associated with depression. In this age group, depressive illness was also determined by physical illness burden and neuroticism. CONCLUSIONS: Our data suggest that the subjective impact of life stressors, although rated as of the same magnitude, plays a less important role in accounting for depression in older age compared to young age. They also indicate an increasing weight of physical illness burden in the prediction of depression occurrence in old age.

Combination of androgen deprivation therapy and radiotherapy for localized prostate cancer in the contemporary era.

Currently, androgen deprivation therapy (ADT) has a well-defined role when administered together with radiotherapy (RT): neo-adjuvant and concurrent combination for intermediate risk-disease and adjuvant therapy for high risk disease. Evidence of this association was generated by randomized trials designed and led approximately 30 years ago; thus the question which arises is how relevant and portable are these data in our current clinical practice? In the present review, we examine the pitfalls of these published randomized controlled trials, their relevance to present daily clinics, where high-dose external beam RT or brachytherapy is applied, as well as the adoption of ADT in patients with concomitant cardiovascular disorders.

Évaluation des effets du counseling d'orientation: Influence de l'alliance de travail et des caractéristiques individuelles.

L'objectif de ce travail est l'analyse des composantes psychologiques et relationnelles en jeu dans le counseling d'orientation, plus particulièrement du rôle de l'alliance de travail et des caractéristiques individuelles des clients en tant que facteurs d'explication du succès de l'intervention. L'étude porte sur un échantillon de 101 personnes, âgées de 15 à 41 ans et impliquées dans une démarche d'accompagnement en orientation scolaire et professionnelle. La satisfaction vis-à-vis de l'intervention, les niveaux d'indécision vocationnelle (CDDQ) au début et à l'issue de l'intervention, l'alliance de travail (WAI), la personnalité (NEO-FFI-R), ainsi que les caractéristiques sociodémographiques ont été évalués à l'aide d'instruments validés. L'impact des consultations est observé à travers une réduction importante du niveau d'indécision, t (87) = 9.27 , p < .001, d = .77. Les résultats montrent une forte association entre l'alliance et la satisfaction, r = .54, p < .001, ainsi qu'un lien négatif entre l'alliance et le niveau d'indécision à l'issue de l'intervention, r = -.31, p < .01. En outre, certaines dimensions de la personnalité, comme le névrosisme ou le caractère consciencieux, contribuent à l'explication des effets observés. Cependant, la personnalité et les variables sociodémographiques ne constituent pas des variables modératrices de la relation entre l'alliance de travail et la satisfaction ou l'indécision à l'issue de l'intervention. Cette étude témoigne que les effets du counseling d'orientation dépendent aussi bien de facteurs cognitifs que de paramètres affectifs et relationnels.

Chemoradiotherapy in malignant glioma: standard of care and future directions.

Glioma has been considered resistant to chemotherapy and radiation. Recently, concomitant and adjuvant chemoradiotherapy with temozolomide has become the standard treatment for newly diagnosed glioblastoma. Conversely (neo-)adjuvant PCV (procarbazine, lomustine, vincristine) failed to improve survival in the more chemoresponsive tumor entities of anaplastic oligoastrocytoma and oligodendroglioma. Preclinical investigations suggest synergism or additivity of radiotherapy and temozolomide in glioma cell lines. Although the relative contribution of the concomitant and the adjuvant chemotherapy, respectively, cannot be assessed, the early introduction of chemotherapy and the simultaneous administration with radiotherapy appear to be key for the improvement of outcome. Epigenetic inactivation of the DNA repair enzyme methylguanine methyltransferase (MGMT) seems to be the strongest predictive marker for outcome in patients treated with alkylating agent chemotherapy. Patients whose tumors do not have MGMT promoter methylation are less likely to benefit from the addition of temozolomide chemotherapy and require alternative treatment strategies. The predictive value of MGMT gene promoter methylation is being validated in ongoing trials aiming at overcoming this resistance by a dose-dense continuous temozolomide administration or in combination with MGMT inhibitors. Understanding of molecular mechanisms allows for rational targeting of specific pathways of repair, signaling, and angiogenesis. The addition of tyrosine kinase inhibitors vatalanib (PTK787) and vandetinib (ZD6474), the integrin inhibitor cilengitide, the monoclonal antibodies bevacizumab and cetuximab, the mammalian target of rapamycin inhibitors temsirolimus and everolimus, and the protein kinase C inhibitor enzastaurin, among other agents, are in clinical investigation, building on the established chemoradiotherapy regimen for newly diagnosed glioblastoma.

Bone marrow mesenchymal stem cells stabilize already-formed aortic aneurysms more efficiently than vascular smooth muscle cells in a rat model.

PURPOSE: Abdominal aortic aneurysms (AAAs) expand because of aortic wall destruction. Enrichment in Vascular Smooth Muscle Cells (VSMCs) stabilizes expanding AAAs in rats. Mesenchymal Stem Cells (MSCs) can differentiate into VSMCs. We have tested the hypothesis that bone marrow-derived MSCs (BM-MSCs) stabilizes AAAs in a rat model. MATERIAL AND METHODS: Rat Fischer 344 BM-MSCs were isolated by plastic adhesion and seeded endovascularly in experimental AAAs using xenograft obtained from guinea pig. Culture medium without cells was used as control group. The main criteria was the variation of the aortic diameter at one week and four weeks. We evaluated the impact of cells seeding on inflammatory response by immunohistochemistry combined with RT-PCR on MMP9 and TIMP1 at one week. We evaluated the healing process by immunohistochemistry at 4 weeks. RESULTS: The endovascular seeding of BM-MSCs decreased AAA diameter expansion more powerfully than VSMCs or culture medium infusion (6.5% ± 9.7, 25.5% ± 17.2 and 53.4% ± 14.4; p = .007, respectively). This result was sustained at 4 weeks. BM-MSCs decreased expression of MMP-9 and infiltration by macrophages (4.7 ± 2.3 vs. 14.6 ± 6.4 mm(2) respectively; p = .015), increased Tissue Inhibitor Metallo Proteinase-1 (TIMP-1), compared to culture medium infusion. BM-MSCs induced formation of a neo-aortic tissue rich in SM-alpha active positive cells (22.2 ± 2.7 vs. 115.6 ± 30.4 cells/surface units, p = .007) surrounded by a dense collagen and elastin network covered by luminal endothelial cells. CONCLUSIONS: We have shown in this rat model of AAA that BM-MSCs exert a specialized function in arterial regeneration that transcends that of mature mesenchymal cells. Our observation identifies a population of cells easy to isolate and to expand for therapeutic interventions based on catheter-driven cell therapy.

Modelling Bone Mineral Density in Swiss Breast Cancer Patients Treated with Letrozole, Tamoxifen and Sequences of Letrozole and Tamoxifen in the BIG 1-98 Study (SAKK 21/07).

Background: Bone health is a concern when treating early stage breast cancer patients with adjuvant aromatase inhibitors. Early detection of patients (pts) at risk of osteoporosis and fractures may be helpful for starting preventive therapies and selecting the most appropriate endocrine therapy schedule. We present statistical models describing the evolution of lumbar and hip bone mineral density (BMD) in pts treated with tamoxifen (T), letrozole (L) and sequences of T and L. Methods: Available dual-energy x-ray absorptiometry exams (DXA) of pts treated in trial BIG 1-98 were retrospectively collected from Swiss centers. Treatment arms: A) T for 5 years, B) L for 5 years, C) 2 years of T followed by 3 years of L and, D) 2 years of L followed by 3 years of T. Pts without DXA were used as a control for detecting selection biases. Patients randomized to arm A were subsequently allowed an unplanned switch from T to L. Allowing for variations between DXA machines and centres, two repeated measures models, using a covariance structure that allow for different times between DXA, were used to estimate changes in hip and lumbar BMD (g/cm2) from trial randomization. Prospectively defined covariates, considered as fixed effects in the multivariable models in an intention to treat analysis, at the time of trial randomization were: age, height, weight, hysterectomy, race, known osteoporosis, tobacco use, prior bone fracture, prior hormone replacement therapy (HRT), bisphosphonate use and previous neo-/adjuvant chemotherapy (ChT). Similarly, the T-scores for lumbar and hip BMD measurements were modeled using a per-protocol approach (allowing for treatment switch in arm A), specifically studying the effect of each therapy upon T-score percentage. Results: A total of 247 out of 546 pts had between 1 and 5 DXA; a total of 576 DXA were collected. Number of DXA measurements per arm were; arm A 133, B 137, C 141 and D 135. The median follow-up time was 5.8 years. Significant factors positively correlated with lumbar and hip BMD in the multivariate analysis were weight, previous HRT use, neo-/adjuvant ChT, hysterectomy and height. Significant negatively correlated factors in the models were osteoporosis, treatment arm (B/C/D vs. A), time since endocrine therapy start, age and smoking (current vs. never).Modeling the T-score percentage, differences from T to L were -4.199% (p = 0.036) and -4.907% (p = 0.025) for the hip and lumbar measurements respectively, before any treatment switch occurred. Conclusions: Our statistical models describe the lumbar and hip BMD evolution for pts treated with L and/or T. The results of both localisations confirm that, contrary to expectation, the sequential schedules do not seem less detrimental for the BMD than L monotherapy. The estimated difference in BMD T-score percent is at least 4% from T to L.

Photodynamic therapy for enhanced drug delivery to tumor

Photodynamic therapy (PDT) has been used as an adjunct to cytoreductive surgery in patients with malignant pleura mesothelioma (MPM). However, it was associated with substantial side effects and found to be only of modest clinical benefit. In contrast, Visudyne®-mediated low-dose PDT has been shown to selectively increase the concentration of macromolecular cytostatic compounds in various tumors grown subpleurally on rodent lungs. Consequently, it was thought that PDT-assisted enhanced tumor penetration for cytostatic agents might be better suited to achieve additional tumor control after cytoreductive surgery for mesothelioma. This effect seems to be mainly related to PDT-mediated modulations of tumor vessels which improve the distribution of circulating, systemically administered chemotherapeutic macromolecular agents. However, the mechanisms involved and the optimization of this effect for therapeutic implications remain to be solved. By using the dorsal skin fold chamber method we demonstrated that both angiogenesis and microcirculation of human mesothelioma xenografts can be continuously assessed in vivo by intravital microscopy. We described a new, simple, reproducible and reliable scoring system for the assessment of tumor angiogenesis and microcirculation in this model, thereby allowing the quantitative description of the neo-vascular network development while avoiding a complicated technical setup. This method can serve as a useful tool for the assessment of novel vessel-targeted therapies against MPM. We then applied this newly established model so as to elucidate the underlying mechanisms of PDT-induced extravasation of macromolecular compounds across the endothelial barrier in tumors and surrounding normal tissue. We found that low-dose PDT selectively enhanced the uptake of macromolecular compounds in human mesothelioma xenografts compared to surrounding normal tissue. Interestingly, this increase of effective permeability of tumor vasculature was not related to the inflammatory stimuli generated by PDT such as the mobilization of leucocytes and their adhesion and penetration of the injured vessel wall. We then used the model for optimizing the drug-light conditions of low- dose PDT in order to obtain maximal leakage of the macromolecular compounds in the tumor with minimal uptake in normal surrounding tissue and we were able to identify such a therapeutic window. With these optimized PDT treatment conditions, we assessed the therapeutic effect of this new treatment concept in vivo by measuring tumor growth rates on subcutaneously grown mesothelioma xenografts in nude mice after low-dose PDT of the tumors following systemically administered liposomal (macromolecular) cisplatin, a cytostatic compound commonly used in clinical practice. We were able to demonstrate that low-dose PDT with optimized drug-light conditions combined with systemic chemotherapy indeed resulted in a reduction in tumor growth compared to chemotherapy or PDT alone. In conclusion, our work demonstrates that low-dose PDT may selectively enhance the uptake of macromolecular cytostatic drugs in superficially growing tumors such as mesotheliomas and opens new perspectives for the treatment of these diseases. - Les effets cytotoxiques de la thérapie photodynamique (PDT) sur le mésothéliome pleural malin (MPM) n'ont pas apporté de bénéfice clinique significatif. Toutefois, une application innovante non cytotoxique de la PDT serait la bienvenue en supplément des chimiothérapies pour améliorer le contrôle local de la tumeur. Le prétraitement des néovaisseaux tumoraux par une PDT à bas régime, qui améliorerait la distribution d'une chimiothérapie administrée par voie systémique de façon concomitante, a attiré une attention particulière pour de futures applications cliniques. Toutefois, les mécanismes impliqués dans cet événement et les implications thérapeutiques de ces changements physiopathologiques restent non résolus. Dans cette thèse, nous avons observé en premier que l'angiogenèse et la microcirculation dans les xénogreffes de mésothéliomes humains peuvent être observées et analysées in vivo par microscopie intravitale. Le nouveau système de score appliqué pour l'évaluation de l'angiogenèse et de la microcirculation tumorale dans cette étude est une méthode simple, reproductible et fiable servant à décrire de manière quantitative le réseau néo-vasculaire en développement, tout en évitant d'utiliser une installation technique compliquée. Ce modèle sert de nouvel outil pour l'évaluation des thérapies anti-vasculaires dirigées contre le MPM. Le modèle animal nouvellement établi a alors été utilisé pour élucider les mécanismes sous-jacents de Γ extravasation d'agents macromoléculaires induite par PDT dans les vaisseaux tumoraux et normaux. Nous avons trouvé que la PDT à fable dose améliore la distribution ciblée de drogues macromoléculaires dans des greffes de mésothéliome humain, de manière sélective pour la tumeur. La perméabilité vasculaire tumorale n'est pas influencée par les stimuli inflammatoires générés par la PDT, ce qui joue un rôle important dans la sélectivité de notre photodynamic drug delivery. Ensuite, nous avons recherché la fenêtre thérapeutique optimale de la PDT pour obtenir une accumulation sélective du colorant macromoléculaire dans le tissu tumoral ainsi qu'une efficacité de la PDT combinée avec une chimiothérapie macromoléculaire sur la croissance tumorale. Nous avons démontré que la PDT à faible dose combinée avec une administration systémique de cisplatine liposomale mène à un ralentissement de la croissance tumorale dans notre modèle de mésothéliome malin humain. En conclusion, l'utilisation de la PDT comme prétraitement pour améliorer sélectivement la distribution d'agents thérapeutiques dans des tumeurs poussant superficiellement est prometteuse. Cette observation fourni une preuve du concept remarquable et garanti la suite des investigations, éventuellement ayant pour but de développer de nouveaux concepts de thérapie pour les patients atteints de mésothéliome. Une PDT intra cavitaire à faible dose après pleuro- pneumonectomie pourrait améliorer la pénétration des agents cytostatiques administrés de façon concomitante par voie systémique dans les îlots tumoraux résiduels, et ainsi améliorer le contrôle local.

Les biomarqueurs prédictifs dans le cancer colorectal [Predictive biomarkers in colorectal cancer]

While for many years the diagnosis and therapy of colon cancer did not change drastically, recently new drugs (irinotecan and oxaliplatin, used in adjuvant or neo-adjuvant approaches) and even more recently the introduction of therapies targeting the epidermal growth factor receptor (EGFR) through the monoclonal antibodies cetuximab and panitumumab, are revolutionizing the field. The finding that only patients with a tumor with a wild type (non mutated) KRAS gene respond to anti-EGFR therapy has also affected the way pathologists address colorectal cancer. Molecular analysis of the KRAS gene has become almost a routine in a very short period of time. Pathologists will have to be prepared for a new era: from standard morphology based diagnostic procedures to the prediction of response to therapy using molecular tools.

Presència de Rousseau a Catalunya: entre el mite i la realitat

En aquest article s’ofereix un perfil del pensament de Rousseau a partir de la seva relació amb la filosofia estoica i la seva dependència respecte de les idees de Montaigne, alhora que es remarca —atenint-se a la Professió de fe del vicari savoià— la dimensió religiosa i espiritual de la seva cosmovisió. Sobre la base d’aquests supòsits es revisa l’impacte de les idees de Rousseau en el Romanticisme del segle xix, sense perdre de vista les crítiques que la seva pedagogia va merèixer dels ideòlegs del Noucentisme (Eugeni d’Ors, Joaquim Xirau). Finalment, es conclou que la presència de la pedagogia de Rousseau en el Moviment de Renovació Pedagògica, viscut durant les primeres dècades del segle xx a Catalunya, constitueix més un horitzó que no pas una realitat bastida sistemàticament i sòlidament.

Anne Gangloff, Dion Chrysostome et les mythes. Hellénisme, communication et philosophie politique, París (J. Millon) 2006.

Thi book, as its author makes clear, is based on a thesis that set out initially to analyse what the myths in the works of Dio Chrysostom actually represented but as Gangloff proceeded whit her research her analysis became rather an examination of how the sophist took over and reinvented myths, adpting them to his own purposes and his own times.

Translation and validation of the Ten-Item-Personality Inventory into spanish and catalan

In response to an increasing need for ever-shorter personality instruments, Gosling, Rentfrow, and Swann (2003) developed the Ten-Item-Personality Inventory (TIPI), which measures the dimensions of the Five Factor Model (FFM) using 10 items (two for each dimension) and can be administered in about one minute. In two studies and using a multi-judge (self and observer) and multi-instrument design, we develop Spanish (Castilian) and Catalan versions of the TIPI and evaluate them in terms of internal consistency, test-retest reliability, convergent, discriminant, and content validity, as well as self-observer correlations. Test-retest correlations were strong, and convergence with the NEO-PI-R factors was significant. There were also strong correlations between observer ratings and the participants’ self-ratings. Despite some inconsistencies with respect to the Agreeableness scale, the Catalan translation and both translations into Spanish of the original TIPI demonstrated sufficient psychometric properties to warrant use as a Five Factor personality measure when the use of longer instruments is not convenient or possible. Furthermore, as the first translation of a brief standard Big Five Instrument into Catalan, this work should facilitate future research on personality in the Catalan-speaking population.
