Irradiation corporelle totale : présent et avenir [Total body irradiation: present and future]

Total body irradiation (TBI) has an established role as preparative regimen for bone-marrow transplantation in the treatment of hematological malignancies. Many randomized trials demonstrated that the clinical outcomes obtained from the association of TBI and cyclophosphamide are equivalent, or, sometimes, better than those based on chemotherapeutic agents. Despite the therapeutic progress of the last years, and the consequent improvement in the overall survival, this preparative regimen remains always associated with a relatively high rate of acute and late toxicity. In this article, we review the actual indications of TBI in clinical practice, and analyze the technological progress in this domain. We focus on the hypothesis that a selective irradiation of the hematopoietic or lymphoid organs is actually possible with intensity-modulated radiotherapy. Technical limits and preliminary results in terms of acute and late toxicities of intensity-modulated TBI are analyzed. With these new technologies, treatment-related toxicity is not anymore a major limiting factor in the preparative regimens for bone-marrow transplantation, allowing for a larger spectrum of TBI indications, a possible extension to patients older than 50 years, or a dose escalation. Preliminary results warrant, however, further evaluation in clinical trials to better assess the impact of this new approach on disease control and the long-term toxicity.

Biomarkers of therapeutic responses in chronic Chagas disease: state of the art and future perspectives

The definition of a biomarker provided by the World Health Organization is any substance, structure, or process that can be measured in the body, or its products and influence, or predict the incidence or outcome of disease. Currently, the lack of prognosis and progression markers for chronic Chagas disease has posed limitations for testing new drugs to treat this neglected disease. Several molecules and techniques to detect biomarkers inTrypanosoma cruzi-infected patients have been proposed to assess whether specific treatment with benznidazole or nifurtimox is effective. Isolated proteins or protein groups from different T. cruzistages and parasite-derived glycoproteins and synthetic neoglycoconjugates have been demonstrated to be useful for this purpose, as have nucleic acid amplification techniques. The amplification of T. cruziDNA using the real-time polymerase chain reaction method is the leading test for assessing responses to treatment in a short period of time. Biochemical biomarkers have been tested early after specific treatment. Cytokines and surface markers represent promising molecules for the characterisation of host cellular responses, but need to be further assessed.

The European Union in North Korea: Current Realities and Paths for Future Engagement – A Qualitative and Quantitative Study

Malgrat la rellevància estratègica i el paper desestabilitzador de Corea del Nord a la regió econòmicament més dinàmica del món, la UE no compta amb cap estratègia clara per involucrar-se amb aquest país. Combinant tècniques d’anàlisi qualitatives i quantitatives, aquest treball pretén descobrir possibles contradiccions internes que impedeixin la definició d'una política exterior europea coherent i efectiva amb respecte a Corea del Nord, així com discrepàncies entre les percepcions d’actors interns de la UE i les d’actors externs. S'han detectat importants diferències d’expectatives i mancances en termes de coherència, tant entre les visions expressades pels actors interns com entre les opinions d’aquests actors i les dels futurs líders sudcoreans enquestats – diferències que fins i tot afecten la promoció dels drets humans

Prognostic and predictive biomarkers in resected colon cancer: current status and future perspectives for integrating genomics into biomarker discovery.

The number of agents that are potentially effective in the adjuvant treatment of locally advanced resectable colon cancer is increasing. Consequently, it is important to ascertain which subgroups of patients will benefit from a specific treatment. Despite more than two decades of research into the molecular genetics of colon cancer, there is a lack of prognostic and predictive molecular biomarkers with proven utility in this setting. A secondary objective of the Pan European Trials in Adjuvant Colon Cancer-3 trial, which compared irinotecan in combination with 5-fluorouracil and leucovorin in the postoperative treatment of stage III and stage II colon cancer patients, was to undertake a translational research study to assess a panel of putative prognostic and predictive markers in a large colon cancer patient cohort. The Cancer and Leukemia Group B 89803 trial, in a similar design, also investigated the use of prognostic and predictive biomarkers in this setting. In this article, the authors, who are coinvestigators from these trials and performed similar investigations of biomarker discovery in the adjuvant treatment of colon cancer, review the current status of biomarker research in this field, drawing on their experiences and considering future strategies for biomarker discovery in the postgenomic era.

The CFSP/ESDP, Parliamentary Accountability, and the ´Future of Europe´ Convention debate

This paper examines the importance that the current Convention on the Future of Europe is giving (or not) to the question of democratic accountability in European foreign and defence policy. As all European Union (EU) member states are parliamentary democracies1, and as there is a European Parliament (EP) which also covers CFSP (Common Foreign and Security Policy) and ESDP (European Security and Defence Policy2) matters, I will concentrate on parliamentary accountability rather than democratic accountability more widely defined. Where appropriate, I will also refer to the work of other transnational parliamentary bodies such as the North Atlantic Assembly or NAA (NATO´s Parliamentary Assembly) or the Western European Union (WEU) Parliamentary Assembly3. The article will consist of three sections. First, I will briefly put the question under study within its wider context (section 1). Then, I will examine the current level of parliamentary accountability in CFSP and defence matters (section 2). Finally, I will consider the current Convention debate and assess how much attention is being given to the question of accountability in foreign and defence policies (section 3). This study basically argues that, once again, there is very little interest in an issue that should be considered as vital for the future democratic development of a European foreign and defence policy. It is important to note however that this paper does not cover the wider debate about how to democratise and make the EU more transparent and closer to its citizens. It concentrates on its Second Pillar because its claim is that very little if any attention is being given to this question

Cellules souches cancéreuses et futures modalités thérapeutiques du cancer. [Cancer stem cells and future therapeutic implications].

A growing body of evidence indicates that a subpopulation of tumor cells, the so-called cancer stem cells (CSCs), drive tumor growth and metastasis and preclude therapy efficiency. CSCs have been isolated in virtually all type of tumors. These findings may have important consequences for clinical prognostic. Current cancer research aims to unravel the CSCs' unique biological mechanisms. The development of new CSCs-targeted treatments shed therefore new hopes in improving cancer therapy.

Tenseness of Riemannian flows

We show that any transversally complete Riemannian foliation &em&F&/em& of dimension one on any possibly non-compact manifold M is tense; namely, (M,&em&F&/em&) admits a Riemannian metric such that the mean curvature form of &em&F&/em& is basic. This is a partial generalization of a result of Domínguez, which says that any Riemannian foliation on any compact manifold is tense. Our proof is based on some results of Molino and Sergiescu, and it is simpler than the original proof by Domínguez. As an application, we generalize some well known results including Masa's characterization of tautness.

Personnes âgées aux urgences: défis actuels et futurs [Older patients at the emergency department: current and future challenges].

Emergency departments are and will be at the front line to face the forthcoming increased use of the health care system by the aging baby boomers cohort. Emergency department services will need to adjust on a quantitative as well as on a qualitative basis to manage the impact of these demographic changes. Various models of care have been developed to improve the care of older geriatric patients in the Emergency department that resulted in favorable results on functional, health, as well as health services utilization outcomes. Key components of these successful models have been identified that require a high level of integration between geriatric and emergency teams.

Euromelanoma: a dermatology-led European campaign against nonmelanoma skin cancer and cutaneous melanoma: past, present and future.

Euromelanoma is a dermatologist-led skin cancer prevention programme conducting an annual screening and public education campaign in over 20 European countries. Within its 10-year history, Euromelanoma has screened over 260,000 individuals across Europe, detecting a significant number of cutaneous melanomas and nonmelanoma skin cancers, identifying high-risk individuals for further surveillance and promoting awareness on the suspicious features of melanoma and the hazardous effects of ultraviolet exposure. In this review article, we summarize the history of the Euromelanoma campaign, present its organizational structure and discuss the results of the campaign in individual countries and on a European scale. Euromelanoma has had a significant impact on melanoma prevention and early diagnosis in participating countries and, despite many challenges, has positively influenced public health attitudes towards regular mole examination and the implementation of preventive measures against skin cancer.

Modalities and future prospects of gene therapy in heart transplantation.

Heart transplantation is the treatment of choice for many patients with end-stage heart failure. Its success, however, is limited by organ shortage, side effects of immunosuppressive drugs, and chronic rejection. Gene therapy is conceptually appealing for applications in transplantation, as the donor organ is genetically manipulated ex vivo before transplantation. Localised expression of immunomodulatory genes aims to create a state of immune privilege within the graft, which could eliminate the need for systemic immunosuppression. In this review, recent advances in the development of gene therapy in heart transplantation are discussed. Studies in animal models have demonstrated that genetic modification of the donor heart with immunomodulatory genes attenuates ischaemia-reperfusion injury and rejection. Alternatively, bone marrow-derived cells genetically engineered with donor-type major histocompatibility complex (MHC) class I or II promote donor-specific hyporesponsiveness. Genetic engineering of naïve T cells or dendritic cells may induce regulatory T cells and regulatory dendritic cells. Despite encouraging results in animal models, however, clinical gene therapy trials in heart transplantation have not yet been started. The best vector and gene to be delivered remain to be identified. Pre-clinical studies in non-human primates are needed. Nonetheless, the potential of gene therapy as an adjunct therapy in transplantation is essentially intact.
