The "reversed" treatment approach for synchronous liver metastases and colorectal cancer. Feasability and first results

Background: The « reversed treatment» approach inverts the treatment sequence of¦advanced synchronous colorectal liver metastases - i.e. the liver metastasis is¦treated first, followed by resection of the primary tumor. Chemotherapy is performed¦before and after liver surgery. We recently started to use a reversed treatment¦approach in selected patients. The aim of this study is to critically assess this new¦treatment modality.¦Methods: Nine patients (7 male, 2 female, mean age 62 years) benefited from this¦new treatment between November 2008 and May 2010. The data were collected¦retrospectively.¦Results: All patients responded to the neoadjuvant chemotherapy. The median¦number of liver metastases was 6 (range 1 - 22). The median size of the largest liver¦metastases was 4.3 cm (range 2.6 - 13 cm). Three patients had portal vein¦embolization prior to liver surgery. Two patients could not complete the treatment.¦One had to undergo emergency surgery for occluding colonic tumor. The second one¦showed liver recurrence before starting the adjuvant chemotherapy. The seven¦patients who completed the treatment are still alive after a median time of 27 months¦(range 17 - 37 months). Seven of them had recurrence (1 rectal, 6 liver). The median¦disease-free survival was 9 months (range 0 - 17 months).¦Conclusion: Based on our preliminary experiences, the reversed strategy shows¦encouraging results for the treatment of advanced synchronous colorectal liver¦metastases in well selected patients. The treatment was generally well tolerated and¦long term survival seems to be prolonged.

The young infant's triangular communication in the family : access to threesome intersubjectivity ? Conceptual considerations and case illustrations

During these last decades, the notion of primary intersubjectivity has gained acceptance among developmentalists and clinicians. But a new challenge is put out to our models by recent findings on the triangular competence of the very young infant, or her capacity to simultaneously communicate with two partners at a time. This discovery raises the question of a collective form of intersubjectivity. Findings on the triangular competence of the 3- to 4-month-old interactions with father and mother in different contexts of the Lausanne trilogue play situation are reviewed and illustrated, with a view to examine whether it is based on a dyadic or triangular program and whether conditions for a threesome form of primary intersubjectivity are fulfilled. The discussion focuses on the revisions of the theory of intersubjectivity, of developmental theory, and of clinical practice these findings call for, pointing toward a three -person psychology too.

Variations in fathers' discourse on fatherhood and in family alliances during infancy

The aim of this pilot study is to analyse the discourse of fathers of toddlers concerning fatherhood and the link between some particularities in the discourse and family alliance. The sample consists of 13 Swiss first time fathers (5 fathers of girls and 8 of boys). In order to evaluate the paternal discourse, the fathers were given a semi-structured interview, which was later analysed using the research package Alceste. The family alliance, i.e., the degree of coordination among the partners when executing a task together, was assessed through the Lausanne Trilogue Play (Fivaz-Depeursinge & Corboz-Warnery, 1999). The main results indicated an interesting link between classes of paternal discourse grouped around the following themes "affective relationship", "daily routine" and "educational goals", and the family alliance (defined in two major categories; functional and problematic alliances). Finally, clinical perspectives on links between paternal representations and family functioning at an interactive level are discussed

Mir211 Is Dysregulated In Conjunctival Melanocytic proliferations

Purpose Downregulation of TRPM1 mRNA, a transient receptor potential cation channel, has been identified in highly metastatic cutaneous melanoma cell lines. TRPM1 mRNA expression is inversely correlated with skin melanoma metastases. Recent evidence has demonstrated that the tumor suppressive activity of TRPM1 is due to miR211 situated in intron 6 of TRPM1. As we have previously identified a downregulation of TRPM1 mRNA expression in conjunctival melanoma, we decided to assess miR211 expression and its potential target gene IGF2R and KCNMA1 in conjunctival melanocytic proliferations. As MITF has been shown to regulate both TRPM1 and mir211 expression, we also assessed MITF expression in our series. Methods Expression of miR211 was assessed by in situ hybridization in 14 conjunctival naevi and 14 conjunctival melanoma. Integrity of miRNA in tissues was evaluated in each sample with the preservation of miR126 expression in endothelial cells. Protein expression of MITF, IGF2R and KCNMA1 was assessed by immunohistochemistry. Statistical analysis was performed with JUMP 8,0 software. In situ hybridization and immunohistochemistry were assessed independently by two observers. Results There were 7 subepithelial nevi and 7 compound nevi. There were 5 female and 9 male. The population mean age was 48.7 ± 6.4 years (SEM). miR211 was found in 11 nevi (79%). MITF was expressed in all the nevi. IGF2R was found in 13 nevi. KCNMA1 was found in 57% of the nevi.The melanoma group was composed of 9 females and 5 males with a mean age of 67 ± 4.8 years (SEM). Using the recent TNM classification, 5 tumors were belonging to the T1, 3 to theT2 and 6 to the T3 categories. miR211 was found in 5 melanoma (36%). There was a significant downregulation of miR211 in the melanoma compared to the nevi (p=0,0219). MITF was found in 13 melanoma (93%). IGF2R and KCNMA1 were respectively found in 71% and 77% of the melanoma. There was no significant differential expression of MITF, KCNMA1 and IGF2R between the nevi and the melanoma as well as no association between miR211 expression and protein expression of two potential target genes Conclusions In vivo miR211 is significantly reduced in conjunctival melanoma compared to conjunctival nevi. No correlation between mir211 expression and two potential target genes KCNMA1 and IGF2R was observed.

Oxidative phosphorylation flexibility in the liver of mice resistant to high-fat diet-induced hepatic steatosis.

OBJECTIVE To identify metabolic pathways that may underlie susceptibility or resistance to high-fat diet-induced hepatic steatosis. RESEARCH DESIGN AND METHODS We performed comparative transcriptomic analysis of the livers of A/J and C57Bl/6 mice, which are, respectively, resistant and susceptible to high-fat diet-induced hepatosteatosis and obesity. Mice from both strains were fed a normal chow or a high-fat diet for 2, 10, and 30 days, and transcriptomic data were analyzed by time-dependent gene set enrichment analysis. Biochemical analysis of mitochondrial respiration was performed to confirm the transcriptomic analysis. RESULTS Time-dependent gene set enrichment analysis revealed a rapid, transient, and coordinate upregulation of 13 oxidative phosphorylation genes after initiation of high-fat diet feeding in the A/J, but not in the C57Bl/6, mouse livers. Biochemical analysis using liver mitochondria from both strains of mice confirmed a rapid increase by high-fat diet feeding of the respiration rate in A/J but not C57Bl/6 mice. Importantly, ATP production was the same in both types of mitochondria, indicating increased uncoupling of the A/J mitochondria. CONCLUSIONS Together with previous data showing increased expression of mitochondrial β-oxidation genes in C57Bl/6 but not A/J mouse livers, our present study suggests that an important aspect of the adaptation of livers to high-fat diet feeding is to increase the activity of the oxidative phosphorylation chain and its uncoupling to dissipate the excess of incoming metabolic energy and to reduce the production of reactive oxygen species. The flexibility in oxidative phosphorylation activity may thus participate in the protection of A/J mouse livers against the initial damages induced by high-fat diet feeding that may lead to hepatosteatosis.

Comparability of health care responsiveness in Europe

The aim of this paper is to measure and to correct for the potential incomparability of responses to the SHARE survey on health care responsiveness. A parametric approach based on the use of anchoring vignettes is applied to cross-sectional data (2006-2007) in eleven European countries. More than 7,000 respondents aged 50 years old and over were asked to assess the quality of health care responsiveness in three domains: waiting time for medical treatment, quality of the conditions in visited health facilities, and communication and involvement in decisions about the treatment. Our results suggest that there is reporting heterogeneity across countries and across individuals within countries, and the degree of heterogeneity varies with the health care domain. Although leading countries in terms of health care responsiveness remain among the most successful even after correction for reporting heterogeneity, one may acknowledge many shifts in the ranking of the other countries.

Couple conjugal et couple co-parental: quelle articulation lors de la transition à la parentalité ?

La venue d'un premier enfant implique d'importants remaniements. Le couple conjugal est mis à rude épreuve et la littérature anglo-saxonne fait état d'une baisse de la satisfaction conjugale durant la période de transition à la parentalité. De plus, au couple conjugal s'ajoutent le couple co-parental (relations entre les parents à propos de leur enfant) et les dyades parentales (parent/enfant). L'articulation entre les sous-systèmes conjugal, co-parental et parental va varier d'une famille à l'autre : prépondérance du parental ou du conjugal, présence d'un co-parentage soutenant ou non, etc. La baisse de la satisfaction conjugale lors de la transition à la parentalité est confirmée dans une étude réalisée en Suisse et présentée dans cet article. Des vignettes cliniques de jeux familiaux illustrent ensuite les différentes articulations possibles du conjugal, du co-parental et du familial. The birth of a first child implies important reorganizations. The marital relationship is under stress and Anglo-Saxon literature shows that there is a decrease of the marital satisfaction during the transition to parenthood. Moreover, when partners become parents, coparenting (relationship between the parents regarding their child) and parental dyads (parent-infant) are added to the marital relationship. The articulation between the conjugal, coparental and parental sub-systems varies from one family to the other : preponderance of the parental or the conjugal subsystem, presence of a supportive co-parenting or not, etc. The decrease of the marital satisfaction during the transition to parenthood is confirmed in a Swiss study and described in this article. Descriptions of family games illustrate then the different possible articulations of the conjugal, coparental and parental subsystems.

L'« Intervention systémique brève » : un manuel thérapeutique

Evaluer l'efficacité d'une thérapie ne devrait pas se limiter à en étudier l'impact sur différentes dimensions pertinentes. En effet, la recherche en psychothérapie insiste sur l'importance de développer des manuels thérapeutiques, afin de décrire ce que les thérapeutes font et donc comprendre ce qui est efficace, ainsi que des protocoles d'adhérence à ces manuels, afin de pouvoir évaluer si les intervenants font effectivement ce qu'ils prétendent faire. Cet article présente le manuel thérapeutique de l'Intervention systémique brève (ISB), un modèle d'intervention en six séances, utilisé dans une consultation pour couples et familles au Département de psychiatrie du CHUV à Lausanne. Ce modèle fait l'objet d'une recherche visant à évaluer son efficacité à court et moyen termes, au moyen de questionnaires remplis par les patients, évaluant différents niveaux : 1) les symptômes individuels, 2) la satisfaction conjugale, 3) la qualité des relations parentales, 4) la qualité des relations coparentales et 5) les relations familiales. L'ISB est un modèle intégratif des principales écoles de thérapie familiale systémique. Pour élaborer le manuel de l'ISB, nous nous sommes basés sur certains principes généraux communs aux différentes approches systémiques. La difficulté d'élaborer un tel manuel thérapeutique intégratif systémique sera discutée.
