Savoir, faire ? Les relations chimériques de la psychanalyse avec la psychiatrie publique et l'université en Suisse romande

C'est souvent dans les institutions psychiatriques que le médecin développe les premiers contacts avec la psychanalyse. L'institution entretient pourtant avec la psychanalyse un rapport chimérique que les sociétés de psychanalyse contribuent à pervertir en restant cloîtrées. Telle pourrait être la thèse de Nicolas Despland qui souhaite, par un article qui défriche le problème, ouvrir la discussion pour trouver des solutions qui importent à tous les protagonistes.

H2O-δD-Fe-III relations of dehydrogenation and dehydration processes in magmatic amphiboles

Stable isotope compositions of a suite of magmatic amphiboles from alkaline basalts and andesitic rocks were examined to constrain the effects of degassing processes on the hydrogen isotope compositions. The Fe3+ (as Fe3+/Fe-total) and H2O contents, as well as the H isotope compositions of the amphiboles, differ markedly (27-58%, 0.5-2.2 wt%, -107 to -15 parts per thousand, respectively) but indicate systematic variations. The observed trends can be explained either as dehydrogenation or dehydration processes, both of which are coupled to oxidation processes, the latter most probably related to O2- substitution within amphiboles. The dehydrogenation-dehydration models can be used to assess the primary compositions of the magmas. As an important example, delta D values of amphiboles of Martian meteorites are discussed in a similar context. Copyright (c) 2006 John Wiley & Sons, Ltd.

Independent relations of left ventricular structure with the 24-h urinary excretion of sodium and aldosterone

Objective: Previous studies reported on the association of left ventricular mass index (LVMI) with urinary sodium or with circulating or urinary aldosterone.We investigated the independent associations of LVMI with the urinary excretion of both sodium and aldosterone. Design and method: We randomly recruited 317 untreated subjects from a White population (45.1%women; mean age 48.2 years).Measurements included echocardiographic left ventricular (LV) properties, the 24 h urinary excretion of sodium and aldosterone, plasma renin activity (PRA), and proximal (RNaprox) and distal (RNadist) renal sodium reabsorption, assessed fromthe endogenous lithium clearance. Inmultivariable-adjusted models,we expressed changes in LVMI per 1 SD increase in the explanatory variables, while accounting for sex, age, systolic blood pressure and the waist-to-hip ratio. Results: LVMI increased independentlywith the urinary excretion of both sodium (+2.48 g/m2; P=0.005) and aldosterone (+2.63 g/m2; P=0.004). Higher sodium excretion was associated with increased mean wall thickness (MWT: +0.126 mm, P=0.054), but with no change in LV end-diastolic diameter (LVID: +0.12mm, P=0.64). In contrast, higher aldosterone excretion was associated with higher LVID (+0.54 mm; P=0.017), but with no change in MWT (+0.070mm; P=0.28).Higher RNadistwas associatedwith lower relativewall thickness (−0.81×10−2, P=0.017), because of opposite trends in LVID(+0.33 mm; P=0.13) and MWT (−0.130mm; P=0.040). LVMI was not associated with PRA or RNaprox. Conclusions: LVMI independently increased with both urinary sodium and aldosterone excretion. IncreasedMWT explained the association of LVMI with urinary sodium and increased LVID the association of LVMI with urinary aldosterone.

Faire et défaire le voisinage : les fêtes de quartier comme reflet de relations sociales et culturelles

Ce livre traque un objet jusqu'ici resté dans l'ombre de l'histoire, le voisinage en milieu urbain. Dans les villes de l'Europe en voie d'industrialisation et d'urbanisation massive, du XVIIIe au XXe siècle, comment approcher les cohabitations quotidiennes ? De la contrainte à l'accommodement, de la sociabilité choisie à la promiscuité subie, des crispations construites aux frontières érigées, de la dénonciation au crime, l'histoire, l'anthropologie et l'urbanisme sont mobilisées pour cette étude novatrice.
