Le concept de test relationnel en psychothérapie: origine, développements et applications aux troubles de la personnalité = The test concept in psychotherapy: origins, developments and application to personality disorders

Le concept de test relationnel (test, en anglais ; Weiss et Sampson, 1986 [16]) est présenté. Ses origines dans les écrits de Freud sont brièvement retracées et son inscription dans la théorie des croyances pathogènes de Weiss présentée. Par ailleurs, les autres éléments de la théorie psychanalytique de Weiss sont présentés (buts thérapeutiques, obstacles, traumas, insight, test relationnel). Toutes ces étapes sont illustrées par des exemples tirés de la littérature. Un développement récent du concept de test relationnel est présenté et appliqué à la psychothérapie des troubles de la personnalité (Sachse, 2003 [14]). Finalement, les auteurs donnent deux brefs exemples de tests relationnels tirés de leur propre pratique de psychothérapeute et discutent des modèles en les comparant entre eux. Des conclusions concernant l'utilité du concept de test relationnel pour la pratique psychothérapeutique et la recherche en psychothérapie sont proposées. The test concept (Weiss and Sampson, 1986 [16]) is presented. Its origins in Freud's works are briefly evoked and its place within the theory of pathogenic beliefs by Weiss presented. We present also the remaining elements of Weiss' psychoanalytic theory which are objectives, obstacles, traumas and insight. Every step of the reflection is illustrated with case examples, drawn from the literature. A recent development of the test concept is presented and applied to the psychotherapy of personality disorders (Sachse, 2003 [14]). Finally, the authors give brief examples of tests having occurred in their own practice as psychotherapists and discuss the models by comparing them among each other. Conclusions are drawn concerning the usefulness of the test concept for psychotherapy practice and research.

Telehealth system (e-CUIDATE) to improve quality of life in breast cancer survivors: rationale and study protocol for a randomized clinical trial.

BACKGROUND Breast cancer survivors suffer physical impairment after oncology treatment. This impairment reduces quality of life (QoL) and increase the prevalence of handicaps associated to unhealthy lifestyle (for example, decreased aerobic capacity and strength, weight gain, and fatigue). Recent work has shown that exercise adapted to individual characteristics of patients is related to improved overall and disease-free survival. Nowadays, technological support using telerehabilitation systems is a promising strategy with great advantage of a quick and efficient contact with the health professional. It is not known the role of telerehabilitation through therapeutic exercise as a support tool to implement an active lifestyle which has been shown as an effective resource to improve fitness and reduce musculoskeletal disorders of these women. METHODS / DESIGN This study will use a two-arm, assessor blinded, parallel randomized controlled trial design. People will be eligible if: their diagnosis is of stages I, II, or IIIA breast cancer; they are without chronic disease or orthopedic issues that would interfere with ability to participate in a physical activity program; they had access to the Internet and basic knowledge of computer use or living with a relative who has this knowledge; they had completed adjuvant therapy except for hormone therapy and not have a history of cancer recurrence; and they have an interest in improving lifestyle. Participants will be randomized into e-CUIDATE or usual care groups. E-CUIDATE give participants access to a range of contents: planning exercise arranged in series with breathing exercises, mobility, strength, and stretching. All of these exercises will be assigned to women in the telerehabilitation group according to perceived needs. The control group will be asked to maintain their usual routine. Study endpoints will be assessed after 8 weeks (immediate effects) and after 6 months. The primary outcome will be QoL measured by The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 version 3.0 and breast module called The European Organization for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life questionnaire. The secondary outcomes: pain (algometry, Visual Analogue Scale, Brief Pain Inventory short form); body composition; physical measurement (abdominal test, handgrip strength, back muscle strength, and multiple sit-to-stand test); cardiorespiratory fitness (International Fitness Scale, 6-minute walk test, International Physical Activity Questionnaire-Short Form); fatigue (Piper Fatigue Scale and Borg Fatigue Scale); anxiety and depression (Hospital Anxiety and Depression Scale); cognitive function (Trail Making Test and Auditory Consonant Trigram); accelerometry; lymphedema; and anthropometric perimeters. DISCUSSION This study investigates the feasibility and effectiveness of a telerehabilitation system during adjuvant treatment of patients with breast cancer. If this treatment option is effective, telehealth systems could offer a choice of supportive care to cancer patients during the survivorship phase.

Perturbation expansions of multilocus fixation probabilities for frequency-dependent selection with applications to the Hill-Robertson effect and to the joint evolution of helping and punishment.

Natural populations are of finite size and organisms carry multilocus genotypes. There are, nevertheless, few results on multilocus models when both random genetic drift and natural selection affect the evolutionary dynamics. In this paper we describe a formalism to calculate systematic perturbation expansions of moments of allelic states around neutrality in populations of constant size. This allows us to evaluate multilocus fixation probabilities (long-term limits of the moments) under arbitrary strength of selection and gene action. We show that such fixation probabilities can be expressed in terms of selection coefficients weighted by mean first passages times of ancestral gene lineages within a single ancestor. These passage times extend the coalescence times that weight selection coefficients in one-locus perturbation formulas for fixation probabilities. We then apply these results to investigate the Hill-Robertson effect and the coevolution of helping and punishment. Finally, we discuss limitations and strengths of the perturbation approach. In particular, it provides accurate approximations for fixation probabilities for weak selection regimes only (Ns < or = 1), but it provides generally good prediction for the direction of selection under frequency-dependent selection.

Increased eotaxin in tears of patients wearing contact lenses

Résumé Introduction : La conjonctivite giganto-papillaire chez des patients porteurs de lentilles de contact survient lors d'une intolérance et/ou d'une allergie aux lentilles de contact. L'éotaxine est un CC chémokine produisant un puissant effet chémotactique sur les éosinophiles, qui sont impliqués dans les allergies. Le but de cette étude est de mesurer le taux d'éotaxine dans les larmes de patients porteurs de lentilles de contact et de le comparer à celui de sujets normaux. Les taux d'éotaxine sont également corrélés avec le degré de conjonctivite giganto-papillaire. Méthode : Environ 10 Ill de larmes ont été collectés avec une rnicropipette en verre chez 16 patients porteurs de lentilles de contact et chez 10 volontaires normaux. La conjonctivite giganto-papillaire a été évaluée selon une échelle de 0 à 4 en référence à des images photographiques de la paupière supérieure réalisées à la lampe à fente. La concentration de l'éotaxine dans les larmes a été mesurée par un ELISA utilisant un anticorps d'éotaxine de souris dirigé contre l'anticorps humain. Pour l'analyse statistique des résultats, le test de Wilcox/Kruskal-Wallis a été utilisé. Résultats : La concentration moyenne d'éotaxine était de 2698 +233 (SEM) pg/ml chez les patients porteurs de lentilles de contact et de 1498 139 pg/ml chez les sujets normaux. La différence était statistiquement significative avec P = 0.0004. Le score moyen des papilles était de 1.75 ±0.19 chez les patients porteurs de lentilles de contact et de 0.2 +0.13 chez les sujets normaux (P <0.0001). Le grading des papilles a pu être mis en relation avec le taux d'éotaxine dans les larmes (R2- 0.6562 avec P <0.0001). Conclusion : Une augmentation du taux d'éotaxine dans les larmes a été mesurée chez les patients porteurs de lentilles de contact. Les taux d'éotaxine ont été corrélés avec la sévérité de la conjonctivite giganto-papillaire. Ces données suggèrent que l'éotaxine pourrait jouer un rôle important dans la formation des papilles. Abstract : Purpose: Giant papillary conjunctivitis in patients wearing contact lenses occurs after intolerance and/or allergy to contact lenses. Eotaxin is a CC chemokine with a potent and specific chemotactic effect for eosinophils, which are involved in allergies. The purpose of this study is to measure the eotaxin levels in tears of patients wearing contact lenses and in normal subjects. Eotaxin levels were also correlated with the grade of giant papillary conjunctivitis. Methods: Around 10µL of tears were collected with glass capillaries in 16 patients wearing contact lenses and in 10 normal volunteers. Giant papillary conjunctivitis was graded from 0 to 4 by reference to standard slit-lamp photographs of the superior tarsal conjunctiva. Eotaxin concentration in tears was measured by ELSA using mouse anti-human eotaxin monoclonal antibodies. For the statistical analysis of the results, the paired Wilcoxon/Kruskai-Wallis test was used. Results: The mean concentration of eotaxin was 2698 ± 233 (SEM) pg/mL in patients wearing contact lenses and 1498 ± 139 pg/mL normal subjects. The difference was statistically significant (P =0.0004). The mean score of papilla grade was 1.75 ± 0.19 in patients wearing contact lenses and 01 ± 0.13 in normal subjects (P < 0.0001). Papilla grade could be correlated to the eotaxin level in tears (R2 = 0.6562 and P< 0.0001), Conclusion: An increase of eotaxin levels in tears was measured in patients wearing contact lenses. Eotaxin levels correlated with the severity of giant papillary conjunctivitis. These data suggest that eotaxin could play a role in papilla formation.

Le contact Gondwana - péri-Gondwana dans le Zanskar oriental (Ladakh-Himalaya)

A l'Est du fleuve Zanskar (Ladakh), la zone de suture de l'Indus sépare les nappes de la bordure nord-indienne du Gondwana (Haut-Himalaya, nappes du Zanskar, cristallin de Tso Morari) des éléments péri·gondwaniens du Trans-himalaya. Des recherches géologiques entreprises entre l'Indus el la Tsarap ont montré que: - la molasse autochlone du Ladakh est surmontée par un édifice de flysch et molasses tertiaires, rétrocharrié vers le NordEst et coiffé par les conglomérats post· éocène moyen du Stok Kangri et une formation eontinentale de molasse rouge; - - la zone de suture comprend deux unités. principales : a) au Nord et au Nord-Ouest, l'unité volcano-sédimentaire de Dras-Nindam avec des conglomérats et flysch crétacés, des brèches massives à radiolarHes et roches vertes; cette unité est accompagnée d'un mélange coloré à roches ultra-basiques, blocs exoti(Iues divers et une méga lentille de brèche carbonatée polygénique à grands Foraminifères (Nummulites ?) ; b) au Sud, l'unité de la Markha, un flysch à lentilles de calcaires plus ou moins marmoréens datée de la base du Jurassique moyen et que nons corrélons avec le Oysch de Lamayuru ; - l'unité complexe de Nimaling représente la terminaison occidentale du crist allin de Rupshn (Tso MOI'ari) ; il comprend un socle gneissique, des roches vert.es et une couverture de schistes quartzitiques, quartzites el dolomies. Cet ensemble est intrudé pal' un granite porphyrique et il est surmonté, en contact tectonique, par une épaisse série métamorphique de calcschistes, shales et grès de faciès schistes lustrés, d'âge inconnu; dans ce tte série, on note au moins trois phases de fortes déformaljons superposées (linéations replissées) ; le long de la vallée de la Markha, le style st.ructural évoque, avec des plis isoclinaux de 2" phase à axes verticaux, une « zone de racine" et pourrait également témoigner de mouvements horizontaux importants; - l'édifice des napp es du Zanskar a été subdivisé en trois unités; il surmonte vers le Nord-Est les schistes lustrés du groupe de Langtang et vient buter vers le Sud-Ouest, le long d'un aceident chevauchant, contre la nappe de Zangla (Haut Himalaya). Les séries sédimentaires (Trias - Crétacé supérieur) sont d'affinité téthysienne. De nouvelles datations sont apportées et nous mettons en évidence, directement à l'Est du fleuve Zanskar, la présence de Crétacé sous faciès calcaires multicolores à microfaune planctique ; transgressif sur les grès de Giumal, ce faciès calcaire déhut.e déjà dans l'Alhien supérieur, c'est-à-dire nellement plus tôt que dans les régions plus orientales de l 'Himalaya; - les nappes du Haut Himalaya comprennent du Nord-Est vers le Sud-Ouest la nappe de Zangla qui chevauche par l'intermédiaire d'une semelle de « Panjal Traps » des témoins écaillés de Paléozoïque inférieur, puis la nappe de cristallin. La nappe de Zangla correspond à l'unité qui, à l 'Ouest du Zanskar supporte la klippe ophiolitique de Spongtang.

Advances in Sequence Analysis: Theory, Methods, Applications

This book gives a general view of sequence analysis, the statistical study of successions of states or events. It includes innovative contributions on life course studies, transitions into and out of employment, contemporaneous and historical careers, and political trajectories. The approach presented in this book is now central to the life-course perspective and the study of social processes more generally. This volume promotes the dialogue between approaches to sequence analysis that developed separately, within traditions contrasted in space and disciplines. It includes the latest developments in sequential concepts, coding, atypical datasets and time patterns, optimal matching and alternative algorithms, survey optimization, and visualization. Field studies include original sequential material related to parenting in 19th-century Belgium, higher education and work in Finland and Italy, family formation before and after German reunification, French Jews persecuted in occupied France, long-term trends in electoral participation, and regime democratization. Overall the book reassesses the classical uses of sequences and it promotes new ways of collecting, formatting, representing and processing them. The introduction provides basic sequential concepts and tools, as well as a history of the method. Chapters are presented in a way that is both accessible to the beginner and informative to the expert.

Modelling changes in stable isotope compositions of minerals during net transfer reactions in a contact aureole: Wollastonite growth at the northern Hunter Mountain Batholith (Death Valley National Park, USA)

One of the world's largest wollastonite deposits was formed at the contact of the northern Hunter Mountain Batholith (California, USA) in Paleozoic sediments. Wollastonite occurs as zones of variable thickness surrounding layers or nodules of quartzite in limestones. A minimum formation temperature of 650 degrees C is estimated from isolated periclase-bearing lenses in that area. Contact metamorphism of siliceous carbonates has produced mineral assemblages that are consistent with heterogeneous, and partly limited infiltration of water-rich fluids, compatible with O-18/O-16 and C-13/C-12 isotopic patterns recorded in carbonates. Oxygen isotope compositions of wollastonites in the study area may also not require infiltration of large quantities of externally-derived fluids that were out of equilibrium with the rocks. 8180 values of wollastonite are high (14.8 parts per thousand to 25.0 parts per thousand; median: 19.7 parts per thousand) and close to those of the host limestone (19.7 parts per thousand to 28 parts per thousand; median: 24.9 parts per thousand) and quartz (18.0 parts per thousand. to 29.1 parts per thousand; median: 22.6 parts per thousand). Isotopic disequilibrium exists at quartz/wollastonite and wollastonite/calcite boundaries. Therefore, classical batch/Rayleigh fractionation models based on reactant and product equilibrium are not applicable to the wollastonite rims. An approach that relies on local instantaneous mass balance for the reactants, based on the wollastonite-forming reaction is suggested as an alternative way to model wollastonite reaction rims. This model reproduces many of the measured delta O-18 values of wollastonite reaction rims of the current study to within +/- 1 parts per thousand, even though the wollastonite compositions vary by almost 10 parts per thousand.
