Travailler sur les articulations interprofessionnelles en périnatalité: un objectif obstétrical [Interprofessional collaboration in perinatality: an obstetrical goal]

In the field of perinatality, development of prenatal diagnosis and neonatal management have been impressive. But these were also associated with the emergence of the increasingly important emotional dimension for parents and professionals. Obstetricians dealing with the difficult breaking of bad news, the uncertainties of prenatal diagnosis and the complex somatic, psychological and social follow-up have to work in a multidisciplinary approach. The securing role of a coherent teamwork is recognised by parents as well as health care providers This article discusses interprofessional relationship as an obstetrical goal and give some landmarks in order to improve the management and the collaboration with parents.

Pandemic influenza control in Europe and the constraints resulting from incoherent public health laws.

Background With the emergence of influenza H1N1v the world is facing its first 21st century global pandemic. Severe Acute Respiratory Syndrome (SARS) and avian influenza H5N1 prompted development of pandemic preparedness plans. National systems of public health law are essential for public health stewardship and for the implementation of public health policy[1]. International coherence will contribute to effective regional and global responses. However little research has been undertaken on how law works as a tool for disease control in Europe. With co-funding from the European Union, we investigated the extent to which laws across Europe support or constrain pandemic preparedness planning, and whether national differences are likely to constrain control efforts. Methods We undertook a survey of national public health laws across 32 European states using a questionnaire designed around a disease scenario based on pandemic influenza. Questionnaire results were reviewed in workshops, analysing how differences between national laws might support or hinder regional responses to pandemic influenza. Respondents examined the impact of national laws on the movements of information, goods, services and people across borders in a time of pandemic, the capacity for surveillance, case detection, case management and community control, the deployment of strategies of prevention, containment, mitigation and recovery and the identification of commonalities and disconnects across states. Results Results of this study show differences across Europe in the extent to which national pandemic policy and pandemic plans have been integrated with public health laws. We found significant differences in legislation and in the legitimacy of strategic plans. States differ in the range and the nature of intervention measures authorized by law, the extent to which borders could be closed to movement of persons and goods during a pandemic, and access to healthcare of non-resident persons. Some states propose use of emergency powers that might potentially override human rights protections while other states propose to limit interventions to those authorized by public health laws. Conclusion These differences could create problems for European strategies if an evolving influenza pandemic results in more serious public health challenges or, indeed, if a novel disease other than influenza emerges with pandemic potential. There is insufficient understanding across Europe of the role and importance of law in pandemic planning. States need to build capacity in public health law to support disease prevention and control policies. Our research suggests that states would welcome further guidance from the EU on management of a pandemic, and guidance to assist in greater commonality of legal approaches across states.

Therapy, diagnosis and prognosis of chronic Chagas disease: insight gained in Argentina

The purpose of this review is to describe research findings regarding chronic Chagas disease in Argentina that have changed the standards of care for patients with Trypanosoma cruzi infection. Indirect techniques (serological tests) are still the main tools for the primary diagnosis of infection in the chronic phase, but polymerase chain reaction has been shown to be promising. The prognosis of patients with heart failure or advanced stages of chagasic cardiomyopathy is poor, but a timely diagnosis during the initial stages of the disease would allow for prescription of appropriate therapies to offer a better quality of life. Treatment of T. cruzi infection is beneficial as secondary prevention to successfully cure the infection or to delay, reduce or prevent the progression to disease and as primary disease prevention by breaking the chain of transmission. Current recommendations have placed the bulk of the diagnostic and treatment responsibility on the Primary Health Care System. Overall, the current research priorities with respect to Chagas disease should be targeted towards (i) the production of new drugs that would provide a shorter treatment course with fewer side effects; (ii) the development of new tools to confirm cure after a full course of treatment during the chronic phase and (iii) biomarkers to identify patients with a high risk of developing diseases.

Vers une sociolinguistique médicale : une approche des objets de langage dans le contexte de la médecine

L'interaction soignant-soigné, dans ses aspects relationnel et communicationnel, a fait l'objet depuis les années 1970 de nombreuses études, inscrites dans une pluralité d'approches théoriques et méthodologiques. L'approche de la sociolinguistique de type médical, dans laquelle s'insère le présent travail de thèse, s'est développée dans le contexte même de ces études. Ce travail s'articule autour de trois sujets de recherche permettant d'illustrer, d'éclairer ainsi que de définir l'approche spécifique de la sociolinguistique médicale et traduisant, par ailleurs, certaines des questions relatives au développement de cette sociolinguistique, qui relève des sciences de la communication et des sciences humaines en médecine. Les deux premiers sujets de recherche se focalisent sur le processus d'échange d'information, central dans l'interaction médicale. Ils portent, pour l'un, sur un format de question spécifique utilisé par des étudiants en médecine dans le cadre d'entretiens avec patients simulés centrés sur l'annonce de mauvaises nouvelles et, pour l'autre, sur la(es) définition(s) d'une unité lexicale attestée dans le contexte communicationnel du VIH/sida. Le troisième sujet de recherche, en corrélation avec les deux autres, traite des défis qui se posent aux chercheurs-sociolinguistes relativement à l'étude et à la production de savoirs sur des questions liées à la santé et à la maladie. - Since the 1970's, many studies, following various theoretical and methodological approaches, have investigated - from a relational and communication point of view - the interaction between health care professionals and patients. The approach of the medical sociolinguistics, on which this PhD thesis is based, has been developed in the context of these studies. This PhD thesis is centred on three research topics illustrating and revealing the specific approach of the medical sociolinguistics and reflecting, as regards the third research topic, on particular issues related to the development of this discipline belonging to both communication sciences and medical humanities. The first two research topics focus on the information sharing process, a main phase and purpose of the medical interaction. They address (i) a particular question design used by medical students with simulated patients in breaking bad news interviews, and (ii) the meaning of a lexical unit used in the HIV/AIDS communication context. The third topic, related with the two other, focuses on the challenges faced by medical sociolinguists while producing knowledge and investigating health- and disease-related issues.

High rates of undiagnosed leprosy and subclinical infection amongst school children in the Amazon Region

Leprosy in children is correlated with community-level factors, including the recent presence of disease and active foci of transmission in the community. We performed clinical and serological examinations of 1,592 randomly selected school children (SC) in a cross-sectional study of eight hyperendemic municipalities in the Brazilian Amazon Region. Sixty-three (4%) SC, with a mean age of 13.3 years (standard deviation = 2.6), were diagnosed with leprosy and 777 (48.8%) were seropositive for anti-phenolic glycolipid-I (PGL-I). Additionally, we evaluated 256 house-hold contacts (HHCs) of the students diagnosed with leprosy; 24 (9.4%) HHC were also diagnosed with leprosy and 107 (41.8%) were seropositive. The seroprevalence of anti-PGL-I was significantly higher amongst girls, students from urban areas and students from public schools (p < 0.0001). Forty-five (71.4%) new cases detected amongst SC were classified as paucibacillary and 59 (93.6%) patients did not demonstrate any degree of physical disability at diagnosis. The results of this study suggest that there is a high rate of undiagnosed leprosy and subclinical infection amongst children in the Amazon Region. The advantages of school surveys in hyperendemic areas include identifying leprosy patients at an early stage when they show no physical disabilities, preventing the spread of the infection in the community and breaking the chain of transmission.

Psychological challenges for the oncology clinician who has to break bad news

Work-related stress of the oncology clinician is not only due to heavy clinical and administrative duties, but also arises when breaking bad news. However, there is important interindividual variation in stress levels during patient encounters, mainly due to the significance the situation represents for the oncologist. A reflection on his own development, his professional identity, and ways of dealing with the patient's suffering can reduce his levels of stress and distress and prevent burnout and other psychiatric disturbances. This chapter summarizes the psychological challenges the oncology clinician is facing when he announces the diagnosis of cancer, deals with the deception of relapse, discusses the transition to palliative care, copes with progression of the disease and uncertainty, and cares for the dying who is facing the unknown. Ways of refiecting on and dealing with these situations from a psychological and communicational perspective are described and illustrated by case vignettes.

High-frequency linkage of co-expressing T-DNA in transgenic Arabidopsis thaliana transformed by vacuum-infiltration of Agrobacterium tumefaciens

The efficiency of co-expression and linkage of distinct T-DNAs present in separate Agrobacterium tumefaciens was analysed in Arabidopsis thaliana transformed by the vacuum infiltration method. Co-expression was monitored by the synthesis of three bacterial proteins involved in the production of polyhydroxybutyrate (PHB) in the plastids. Out of 80 kanamycin-resistant transgenic plants analysed, 13 plants were co-transformed with the two distinct T-DNAs and produced PHB. Of those, 7 lines had a kanamycin-resistance segregation ratio consistent with the presence of a single functional insert. Genetic linkage between the distinct T-DNAs was demonstrated for all 13 PHB-producing lines, while physical linkage between the distinct T-DNAs was shown for 12 out of 13 lines. T-DNAs were frequently linked in an inverted orientation about the left borders. Transformation of A. thaliana by the co-infiltration of two A. tumefaciens containing distinct T-DNAs is, thus, an efficient approach for the integration and expression of several transgenes at a single locus. This approach will facilitate the creation and study of novel metabolic pathways requiring the expression of numerous transgenes.

"I don't know how you are" or indirect questioning in oncology interviews: an ongoing exploratory study

Background: The exploratory study is part of an evaluation of the pre-graduate teaching of communication skills (Lausanne Medical School). It is based on the data of a project highlighting the impact of individualized vs. group training for medicine students in breaking bad news to simulated patients who are diagnosed with cancer. The analysis of the video-taped interviews of the students (N=63) with the RIAS has shown a current usage of utterances such as I don't know if -you have any plans for the future / you have already heard about chemotherapy / ... or I don't know how -you are feeling today after this surgery / you like that all this stuff takes place / ...Aim: The present study questions the specificity of these assertive utterances used as questions (indirect), the specificity of their content, and their intentionality - specific vs. exploratory.Methods: The mentioned utterances are qualitatively analyzed (content analysis, intentionality analysis, etc).Results: 26 students (41%) used 1 to 6 times I don't know utterances during the interviews that contain 53 of such utterances in total. In contrast, they are atypical in an oncologist sample who conducted similar interviews (N=31; 4 oncologist used them 1 to 2 times). In more than half of the cases (29/53), simulated patients interpret I don't know questions as giving them a space to speak (open responses). Conclusions: The atypicality of the I don't know utterances in the oncologist sample may have linguistic explanations in terms of generational marker, but the specificity of the content suggests psychological explanations in terms of defense mechanism as well (marker of "toning down" or insecurity as regards the discussed topic).Keywords: Breaking bad news, communication skills, oncology, pre-graduate medical education, indirect questioning

The Distant neighbors — EU, Middle East, North Africa and the Euro-Mediterranean Partnership

The Barcelona Euro-Mediterranean Conference (1995) was intended to be a launching pad" for creating a new, innovative relationship between the EU-Fifteen and a selected set of non-member Middle Eastern and North African countries. The Barcelona Process was to become the European Union´s first attempt, of several, to create postmodern inclusive policy spheres as a way to deal with the post-enlargement problems of ´ins´ and outs´ in its immediate periphery. Nevertheless, in spite of geographical proximity, common problems and stated interest in creating amorphous EU borders in different sectors, the Euro-Mediterranean Partnership is today all but abandoned. This paper will examine some of the factors behind the current degeneration of the EU´s post-bipolar foreign policy strategy in the Mediterranean, by exploring the dialectic between the Union´s desire to expand its geopolitical, economic and cultural boundaries and the need to secure its territorial area (from migration, proliferation, social instability etc.). In the final part of the paper some suggestions for how to revive the relationship across the Mare Nostrum will be forwarded.

The Cooperation on Justice and Home Affairs and the Enlargement of the European Union

This working – paper will be focused on three key issues: • How will affect the enlargement to the Justice and Home Affairs Cooperation. Especially, the absortion of Schenguen Agreements and the overall JHA by the candidate countries. • The enlargement impact over the European Immigraton Policy and the specific policies carried out by the EU Member States. The main question is the free movement of persons safeguard, in order to protect external borders of European Union. • An analysis of September, 11 attacks against U.S.A might be necessary to understand the future changes on JHA policy.

Tri-sector partnerships in social entrepreneurship: discourse and practice of the actors from the circles of action and reflection

This article discusses the construction of tri-sector partnerships in three projects conducted in Brazil in different fields of intervention of public policy (access to water, basic education and performance of boards of rights of children and adolescents). Collaborative articulations involving the players from three sectors (the State, civil society and the market) are practices that are little studied in the Brazilian and even in the international context, as tri-sector partnerships are rare, despite the proliferation of lines of discourse in support of alliances between governments and civil society or between companies and NGOs in the management of public policy. As a research strategy, this study resorted to cooperative inquiry, a method that involves breaking down the boundaries between the subjects and the objects of the analysis. Besides working toward a better understanding of the challenges of building tri-sector partnerships in the Brazilian context, the article also tries to show the relevance to public policy studies of investigative methods based on the subjects studied, as a means of developing an understanding of the practices, lines of discourse and dilemmas linked to social action in social programs.

Strong reproductive barriers in a narrow hybrid zone of West-Mediterranean green toads (Bufo viridis subgroup) with Plio-Pleistocene divergence

Background One key question in evolutionary biology deals with the mode and rate at which reproductive isolation accumulates during allopatric speciation. Little is known about secondary contacts of recently diverged anuran species. Here we conduct a multi-locus field study to investigate a contact zone between two lineages of green toads with an estimated divergence time of 2.7 My, and report results from preliminary experimental crosses. Results The Sicilian endemic Bufo siculus and the Italian mainland-origin B. balearicus form a narrow hybrid zone east of Mt. Etna. Despite bidirectional mtDNA introgression over a ca. 40 km North-South cline, no F1 hybrids could be found, and nuclear genomes display almost no admixture. Populations from each side of the contact zone showed depressed genetic diversity and very strong differentiation (FST = 0.52). Preliminary experimental crosses point to a slightly reduced fitness in F1 hybrids, a strong hybrid breakdown in backcrossed offspring (F1 x parental, with very few reaching metamorphosis) and a complete and early mortality in F2 (F1 x F1). Conclusion Genetic patterns at the contact zone are molded by drift and selection. Local effective sizes are reduced by the geography and history of the contact zone, B. balearicus populations being at the front wave of a recent expansion (late Pleistocene). Selection against hybrids likely results from intrinsic genomic causes (disruption of coadapted sets of genes in backcrosses and F2-hybrids), possibly reinforced by local adaptation (the ranges of the two taxa roughly coincide with the borders of semiarid and arid climates). The absence of F1 in the field might be due to premating isolation mechanisms. Our results, show that these lineages have evolved almost complete reproductive isolation after some 2.7 My of divergence, contrasting sharply with evidence from laboratory experiments that some anuran species may still produce viable F1 offspring after > 20 My of divergence.

CD30-positive peripheral T-cell lymphomas share molecular and phenotypic features.

Peripheral T-cell lymphoma, not otherwise specified is a heterogeneous group of aggressive neoplasms with indistinct borders. By gene expression profiling we previously reported unsupervised clusters of peripheral T-cell lymphomas, not otherwise specified correlating with CD30 expression. In this work we extended the analysis of peripheral T-cell lymphoma molecular profiles to prototypical CD30(+) peripheral T-cell lymphomas (anaplastic large cell lymphomas), and validated mRNA expression profiles at the protein level. Existing transcriptomic datasets from peripheral T-cell lymphomas, not otherwise specified and anaplastic large cell lymphomas were reanalyzed. Twenty-one markers were selected for immunohistochemical validation on 80 peripheral T-cell lymphoma samples (not otherwise specified, CD30(+) and CD30(-); anaplastic large cell lymphomas, ALK(+) and ALK(-)), and differences between subgroups were assessed. Clinical follow-up was recorded. Compared to CD30(-) tumors, CD30(+) peripheral T-cell lymphomas, not otherwise specified were significantly enriched in ALK(-) anaplastic large cell lymphoma-related genes. By immunohistochemistry, CD30(+) peripheral T-cell lymphomas, not otherwise specified differed significantly from CD30(-) samples [down-regulated expression of T-cell receptor-associated proximal tyrosine kinases (Lck, Fyn, Itk) and of proteins involved in T-cell differentiation/activation (CD69, ICOS, CD52, NFATc2); upregulation of JunB and MUM1], while overlapping with anaplastic large cell lymphomas. CD30(-) peripheral T-cell lymphomas, not otherwise specified tended to have an inferior clinical outcome compared to the CD30(+) subgroups. In conclusion, we show molecular and phenotypic features common to CD30(+) peripheral T-cell lymphomas, and significant differences between CD30(-) and CD30(+) peripheral T-cell lymphomas, not otherwise specified, suggesting that CD30 expression might delineate two biologically distinct subgroups.
