Infirmier en psychiatrie de liaison : développement de la supervision en milieu somatique [Liaison psychiatry nurse: The development of supervision in somatic medicine].

BACKGROUND: Over the years, somatic care has become increasingly specialized. Furthermore, a rising number of patients requiring somatic care also present with a psychiatric comorbidity. As a consequence, the time and resources needed to care for these patients can interfere with the course of somatic treatment and influence the patient-caregiver relationship. In the light of these observations, the Liaison Psychiatry Unit at the University Hospital in Lausanne (CHUV) has educated its nursing staff in order to strengthen its action within the general care hospital. What has been developed is a reflexive approach through supervision of somatic staff, in order to improve the efficiency of liaison psychiatry interventions with the caregivers in charge of patients. The kind of supervision we have developed is the result of a real partnership with somatic staff. Besides, in order to better understand the complexity of interactions between the two systems involved, the patient's and the caregivers', we use several theoretical references in an integrative manner. PSYCHOANALYTICAL REFERENCE: The psychoanalytical model allows us to better understand the dynamics between the supervisor and the supervised group in order to contain and give meaning to the affects arising in the supervision space. "Containing function" and "transitional phenomena" refer to the experience in which emotions can find a space where they can be taken in and processed in a secure and supportive manner. These concepts, along with that of the "psychic envelope", were initially developed to explain the psychological development of the baby in its early interactions with its mother or its surrogate. In the field of supervision, they allow us to be aware of these complex phenomena and the diverse qualities to which a supervisor needs to resort, such as attention, support and incentive, in order to offer a secure environment. SYSTEMIC REFERENCE: A new perspective of the patient's complexity is revealed by the group's dynamics. The supervisor's attention is mainly focused on the work of affects. However, these are often buried under a defensive shell, serving as a temporary protection, which prevents the caregiver from recognizing his or her own emotions, thereby enhancing the difficulties in the relationship with the patient. Whenever the work of putting emotions into words fail, we use "sculpting", a technique derived from the systemic model. Through the use of this type of analogical language, affects can emerge without constraint or feelings of danger. Through "playing" in that "transitional space", new exchanges appear between group members and allow new behaviors to be conceived. In practice, we ask the supervisee who is presenting a complex situation, to design a spatial representation of his or her understanding of the situation, through the display of characters significant to the situation: the patient, somatic staff members, relatives of the patient, etc. In silence, the supervisee shapes the characters into postures and arranges them in the room. Each sculpted character is identified, named, and positioned, with his or her gaze being set in a specific direction. Finally the sculptor shapes him or herself in his or her own role. When the sculpture is complete and after a few moments of fixation, we ask participants to express themselves about their experience. By means of this physical representation, participants to the sculpture discover perceptions and feelings that were unknown up to then. Hence from this analogical representation a reflection and hypotheses of understanding can arise and be developed within the group. CONCLUSION: Through the use of the concepts of "containing function" and "transitional space" we position ourselves in the scope of the encounter and the dialog. Through the use of the systemic technique of "sculpting" we promote the process of understanding, rather than that of explaining, which would place us in the position of experts. The experience of these encounters has shown us that what we need to focus on is indeed what happens in this transitional space in terms of dynamics and process. The encounter and the sharing of competencies both allow a new understanding of the situation at hand, which has, of course, to be verified in the reality of the patient-caregiver relationship. It is often a source of adjustment for interpersonal skills to recover its containing function in order to enable caregiver to better respond to the patient's needs.

Comparative genome analysis of Pseudomonas knackmussii B13, the first bacterium known to degrade chloroaromatic compounds.

Pseudomonas knackmussii B13 was the first strain to be isolated in 1974 that could degrade chlorinated aromatic hydrocarbons. This discovery was the prologue for subsequent characterization of numerous bacterial metabolic pathways, for genetic and biochemical studies, and which spurred ideas for pollutant bioremediation. In this study, we determined the complete genome sequence of B13 using next generation sequencing technologies and optical mapping. Genome annotation indicated that B13 has a variety of metabolic pathways for degrading monoaromatic hydrocarbons including chlorobenzoate, aminophenol, anthranilate and hydroxyquinol, but not polyaromatic compounds. Comparative genome analysis revealed that B13 is closest to Pseudomonas denitrificans and Pseudomonas aeruginosa. The B13 genome contains at least eight genomic islands [prophages and integrative conjugative elements (ICEs)], which were absent in closely related pseudomonads. We confirm that two ICEs are identical copies of the 103 kb self-transmissible element ICEclc that carries the genes for chlorocatechol metabolism. Comparison of ICEclc showed that it is composed of a variable and a 'core' region, which is very conserved among proteobacterial genomes, suggesting a widely distributed family of so far uncharacterized ICE. Resequencing of two spontaneous B13 mutants revealed a number of single nucleotide substitutions, as well as excision of a large 220 kb region and a prophage that drastically change the host metabolic capacity and survivability.

L’eficà cia de les suspensions judicials amb obligació de tractament de deshabituació. Factors que poden influir en la reducció o no de reincidència

Aquesta recerca està motivada per l’interès en les Mesures Penals Alternatives, concretament, en les suspensions judicials com a mesura més adient per a determinats subjectes amb perfils toxicològics i que requereixen d’una intervenció que es pot abordar en context comunitari. Per tal de valorar la seva eficàcia, l’equip d’investigadors s’ha centrat en els índexs de reincidència i aquells factors que poden influir a partir de l’anàlisi estadística d’una mostra de 237 subjectes sotmesos a l’obligació de tractament de deshabituació. Observant l’índex de reincidència, en funció de l’anàlisi de variables sociopersonals i judicials dels subjectes, es busquen aquells indicadors que poden ser eficaços per reduir la comissió de nous fets delictius. Del resultats obtinguts, es conclou que variables com una bona adherència familiar, una estabilitat laboral així com la finalització correcta d’un tractament de deshabituació aporten uns nivells de reincidència baixos. Igualment, es justifica l’atorgament de suspensions judicials com a eina punitiva més eficaç per a aquells subjectes amb característiques toxicològiques i necessitats rehabilitadores a causa de la seva addicció, atès que els nivells de reincidència obtinguts en aquesta recerca aporten uns índexs més baixos que els nivells actuals de reincidència penitenciària (cal tenir en compte, però, la diferència de perfils). Es conclou que aquestes mesures penals alternatives són una eina més integradora ja que es desenvolupen en l’entorn comunitari.

La eficacia de las suspensiones judiciales con obligación de tratamiento de deshabituación. Factores que pueden influir en la reducción o no de reincidencia

Esta investigación está motivada por el interés por las suspensiones judiciales como medida más adecuada para determinados sujetos con perfiles toxicológicos y que requieren una intervención que se puede abordar en un contexto comunitario. Con el fin de valorar su eficacia, el equipo de investigadores se ha centrado en los índices de reincidencia y aquellos factores que pueden influir a partir del análisis estadístico de una muestra de 237 sujetos sometidos a la obligación de tratamiento de deshabituación. Observando el índice de reincidencia, en función del análisis de variables sociopersonales y judiciales de los sujetos, se buscan aquellos indicadores que pueden ser eficaces para reducir la comisión de nuevos hechos delictivos. De los resultados obtenidos, se concluye que variables como una buena adherencia familiar, la estabilidad laboral o la finalización correcta de un tratamiento de deshabituación aportan unos niveles de reincidencia bajos Asimismo, se justifica el otorgamiento de suspensiones judiciales como herramienta punitiva más eficaz para aquellos sujetos con características toxicológicas y necesidades rehabilitadoras debido a su adicción, dado que los niveles de reincidencia obtenidos en esta investigación aportan unos índices más bajos que los niveles actuales de reincidencia penitenciaria (siempre teniendo en cuenta la diferencia de perfiles). Se concluye en este estudio que la aplicación de estas medidas penales alternativas son una herramienta más integradora debido a que se desarrolla dentro del entorno comunitario.

European Integration Without EU Membership : Models, Experiences, Perspectives

At the beginning of the 1990s, the concept of "European integration" could still be said to be fairly unambiguous. Nowadays, it has become plural and complex almost to the point of unintelligibility. This is due, of course, to the internal differentiation of EU membership, with several Member States pulling out of key integrative projects such as establishing an area without frontiers, the "Schengen" area, and a common currency. But this is also due to the differentiated extension of key integrative projects to European non-EU countries - Schengen is again a case in point. Such processes of "integration without membership", the focus of the present publication, are acquiring an ever-growing topicality both in the political arena and in academia. International relations between the EU and its neighbouring countries are crucial for both, and their development through new agreements features prominently on the continent's political agenda. Over and above this aspect, the dissemination of EU values and standards beyond the Union's borders raises a whole host of theoretical and methodological questions, unsettling in some cases traditional conceptions of the autonomy and separation of national legal orders. This publication brings together the papers presented at the Integration without EU Membership workshop held in May 2008 at the EUI (Max Weber Programme and Department of Law). It aims to compare different models and experiences of integration between the EU, on the one hand, and those European countries that do not currently have an accession perspective on the other hand. In delimiting the geographical scope of the inquiry, so as to scale it down to manageable proportions, the guiding principles have been to include both the "Eastern" and "Western" neighbours of the EU, and to examine both structured frameworks of cooperation, such as the European Neighbourhood Policy and the European Economic Area, and bilateral relations developing on a more ad hoc basis. These principles are reflected in the arrangement of the papers, which consider in turn the positions of Ukraine, Russia, Norway, and Switzerland in European integration - current standing, perspectives for evolution, consequences in terms of the EU-ization of their respective legal orders1. These subjects are examined from several perspectives. We had the privilege of receiving contributions from leading practitioners and scholars from the countries concerned, from EU highranking officials, from prominent specialists in EU external relations law, and from young and talented researchers. We wish to thank them all here for their invaluable insights. We are moreover deeply indebted to Marise Cremona (EUI, Law Department, EUI) for her inspiring advice and encouragement, as well as to Ramon Marimon, Karin Tilmans, Lotte Holm, Alyson Price and Susan Garvin (Max Weber Programme, EUI) for their unflinching support throughout this project. A word is perhaps needed on the propriety and usefulness of the research concept embodied in this publication. Does it make sense to compare the integration models and experiences of countries as different as Norway, Russia, Switzerland, and Ukraine? Needless to say, this list of four evokes a staggering diversity of political, social, cultural, and economic conditions, and at least as great a diversity of approaches to European integration. Still, we would argue that such diversity only makes comparisons more meaningful. Indeed, while the particularities and idiosyncratic elements of each "model" of integration are fully displayed in the present volume, common themes and preoccupations run through the pages of every contribution: the difficulty in conceptualizing the finalité and essence of integration, which is evident in the EU today but which is greatly amplified for non-EU countries; the asymmetries and tradeoffs between integration and autonomy that are inherent in any attempt to participate in European integration from outside; the alteration of deeply seated legal concepts, and concepts about the law, that are already observable in the most integrated of the non-EU countries concerned. These issues are not transient or coincidental: they are inextricably bound up with the integration of non-EU countries in the EU project. By publishing this collection, we make no claim to have dealt with them in an exhaustive, still less in a definitive manner. Our ambition is more modest: to highlight the relevance of these themes, to place them more firmly on the scientific agenda, and to provide a stimulating basis for future research and reflection.

Generative FDG-PET and MRI model of aging and disease progression in Alzheimer's disease.

The failure of current strategies to provide an explanation for controversial findings on the pattern of pathophysiological changes in Alzheimer's Disease (AD) motivates the necessity to develop new integrative approaches based on multi-modal neuroimaging data that captures various aspects of disease pathology. Previous studies using [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) and structural magnetic resonance imaging (sMRI) report controversial results about time-line, spatial extent and magnitude of glucose hypometabolism and atrophy in AD that depend on clinical and demographic characteristics of the studied populations. Here, we provide and validate at a group level a generative anatomical model of glucose hypo-metabolism and atrophy progression in AD based on FDG-PET and sMRI data of 80 patients and 79 healthy controls to describe expected age and symptom severity related changes in AD relative to a baseline provided by healthy aging. We demonstrate a high level of anatomical accuracy for both modalities yielding strongly age- and symptom-severity- dependant glucose hypometabolism in temporal, parietal and precuneal regions and a more extensive network of atrophy in hippocampal, temporal, parietal, occipital and posterior caudate regions. The model suggests greater and more consistent changes in FDG-PET compared to sMRI at earlier and the inversion of this pattern at more advanced AD stages. Our model describes, integrates and predicts characteristic patterns of AD related pathology, uncontaminated by normal age effects, derived from multi-modal data. It further provides an integrative explanation for findings suggesting a dissociation between early- and late-onset AD. The generative model offers a basis for further development of individualized biomarkers allowing accurate early diagnosis and treatment evaluation.

Towards a dynamic model of e-commerce: environmental, technological and organisational drivers of B2C along time

Despite the important benefits for firms of commercial initiatives on the Internet, e-commerce is still an emerging distribution channel, even in developed countries. Thus, more needs to be known about the mechanisms affecting its development. A large number of works have studied firms¿ e-commerce adoption from technological, intraorganizational, institutional, or other specific perspectives, but there is a need for adequately tested integrative frameworks. Hence, this work proposes and tests a model of firms¿ business-to-consumer (called B2C) e-commerce adoption that is founded on a holistic vision of the phenomenon. With this integrative approach, the authors analyze the joint influence of environmental, technological, and organizational factors; moreover, they evaluate this effect over time. Using various representative Spanish data sets covering the period 1996-2005, the findings demonstrate the suitability of the holistic framework. Likewise, some lessons are learned from the analysis of the key building blocks. In particular, the current study provides evidence for the debate about the effect of competitive pressure, since the findings show that competitive pressure disincentivizes e-commerce adoption in the long term. The results also show that the development or enrichment of the consumers¿ consumption patterns, the technological readiness of the market forces, the firm¿s global scope, and its competences in innovation continuously favor e-commerce adoption.

Comparison of molecular signatures from multiple skin diseases identifies mechanisms of immunopathogenesis.

The ability to obtain gene expression profiles from human disease specimens provides an opportunity to identify relevant gene pathways, but is limited by the absence of data sets spanning a broad range of conditions. Here, we analyzed publicly available microarray data from 16 diverse skin conditions in order to gain insight into disease pathogenesis. Unsupervised hierarchical clustering separated samples by disease as well as common cellular and molecular pathways. Disease-specific signatures were leveraged to build a multi-disease classifier, which predicted the diagnosis of publicly and prospectively collected expression profiles with 93% accuracy. In one sample, the molecular classifier differed from the initial clinical diagnosis and correctly predicted the eventual diagnosis as the clinical presentation evolved. Finally, integration of IFN-regulated gene programs with the skin database revealed a significant inverse correlation between IFN-β and IFN-γ programs across all conditions. Our study provides an integrative approach to the study of gene signatures from multiple skin conditions, elucidating mechanisms of disease pathogenesis. In addition, these studies provide a framework for developing tools for personalized medicine toward the precise prediction, prevention, and treatment of disease on an individual level.

Carbon isotope fractionation for cotton genotype selection

The objective of this work was to evaluate the carbon isotope fractionation as a phenomic facility for cotton selection in contrasting environments and to assess its relationship with yield components. The experiments were carried out in a randomized block design, with four replicates, in the municipalities of Santa Helena de Goiás (SHGO) and Montividiu (MONT), in the state of Goiás, Brazil. The analysis of carbon isotope discrimination (Δ) was performed in 15 breeding lines and three cultivars. Subsequently, the root growth kinetic and root system architecture from the selected genotypes were determined. In both locations, Δ analyses were suitable to discriminate cotton genotypes. There was a positive correlation between Δ and seed-cotton yield in SHGO, where water deficit was more severe. In this site, the negative correlations found between Δ and fiber percentage indicate an integrative effect of gas exchange on Δ and its association with yield components. As for root robustness and growth kinetic, the GO 05 809 genotype performance contributes to sustain the highest values of Δ found in MONT, where edaphoclimatic conditions were more suitable for cotton. The use of Δ analysis as a phenomic facility can help to select cotton genotypes, in order to obtain plants with higher efficiency for gas exchange and water use.

The spiritual needs model: spirituality assessment in the geriatric hospital setting

Clinicians increasingly agree that it is important to assess patients' spirituality and to incorporate this dimension into the care of elderly persons, in order to enhance patient-centered care. However, models of integrative care that take into account the spiritual dimension of the patient are needed in order to promote a holistic approach to care. This research defines a concept of spirituality in the hospitalized elderly person and develops a model on which to base spirituality assessment in the hospital setting. The article presents in detail the different stages in the conceptualization of The Spiritual Needs Model.

Early, low-level auditory-somatosensory multisensory interactions impact reaction time speed.

Several lines of research have documented early-latency non-linear response interactions between audition and touch in humans and non-human primates. That these effects have been obtained under anesthesia, passive stimulation, as well as speeded reaction time tasks would suggest that some multisensory effects are not directly influencing behavioral outcome. We investigated whether the initial non-linear neural response interactions have a direct bearing on the speed of reaction times. Electrical neuroimaging analyses were applied to event-related potentials in response to auditory, somatosensory, or simultaneous auditory-somatosensory multisensory stimulation that were in turn averaged according to trials leading to fast and slow reaction times (using a median split of individual subject data for each experimental condition). Responses to multisensory stimulus pairs were contrasted with each unisensory response as well as summed responses from the constituent unisensory conditions. Behavioral analyses indicated that neural response interactions were only implicated in the case of trials producing fast reaction times, as evidenced by facilitation in excess of probability summation. In agreement, supra-additive non-linear neural response interactions between multisensory and the sum of the constituent unisensory stimuli were evident over the 40-84 ms post-stimulus period only when reaction times were fast, whereas subsequent effects (86-128 ms) were observed independently of reaction time speed. Distributed source estimations further revealed that these earlier effects followed from supra-additive modulation of activity within posterior superior temporal cortices. These results indicate the behavioral relevance of early multisensory phenomena.

Classifying minimally disabled multiple sclerosis patients from resting state functional connectivity.

Multiple sclerosis (MS), a variable and diffuse disease affecting white and gray matter, is known to cause functional connectivity anomalies in patients. However, related studies published to-date are post hoc; our hypothesis was that such alterations could discriminate between patients and healthy controls in a predictive setting, laying the groundwork for imaging-based prognosis. Using functional magnetic resonance imaging resting state data of 22 minimally disabled MS patients and 14 controls, we developed a predictive model of connectivity alterations in MS: a whole-brain connectivity matrix was built for each subject from the slow oscillations (<0.11Hz) of region-averaged time series, and a pattern recognition technique was used to learn a discriminant function indicating which particular functional connections are most affected by disease. Classification performance using strict cross-validation yielded a sensitivity of 82% (above chance at p<0.005) and specificity of 86% (p<0.01) to distinguish between MS patients and controls. The most discriminative connectivity changes were found in subcortical and temporal regions, and contralateral connections were more discriminative than ipsilateral connections. The pattern of decreased discriminative connections can be summarized post hoc in an index that correlates positively (&#961;=0.61) with white matter lesion load, possibly indicating functional reorganisation to cope with increasing lesion load. These results are consistent with a subtle but widespread impact of lesions in white matter and in gray matter structures serving as high-level integrative hubs. These findings suggest that predictive models of resting state fMRI can reveal specific anomalies due to MS with high sensitivity and specificity, potentially leading to new non-invasive markers.
