Hacia una reformulación sistémica del “Síndrome de Alienación Parental”. Estudio de un caso.

El objetivo del presente estudio es realizar una lectura de una situación de alienación parental en un divorcio conflictivo desde un enfoque sistémico-relacional, respondiendo a la falta de modelos de intervención para dicha casuística y considerando poco holístico el planteamiento defendido bajo la categoría Síndrome de Alienación Parental (SAP), descrita por Gardner el año 1985. Se analizan con metodología cualitativa cinco sesiones de psicoterapia de una familia de tres miembros derivada judicialmente por el rechazo de la hija a mantener contacto con la madre. Atendiendo a sus respectivas narrativas en relación a la pareja, los resultados muestran una mitología compartida en el pasado y una ruptura de la misma, en el caso de la madre. Se observa una precaria gestión del cambio, así como un conflicto comunicacional que impide desarrollar nuevas estrategias narrativas tras la separación. Los resultados permiten apoyar la apertura de líneas de investigación que contribuyan a una reformulación del SAP desde una perspectiva más profunda que aprehenda la complejidad de lo llamamos las Prácticas Alienadoras Familiares (PAF).

Purification and characterization of two enantioselective alpha-ketoglutarate-dependent dioxygenases, RdpA and SdpA, from Sphingomonas herbicidovorans MH.

Alpha-ketoglutarate-dependent (R)-dichlorprop dioxygenase (RdpA) and alpha-ketoglutarate-dependent (S)-dichlorprop dioxygenase (SdpA), which are involved in the degradation of phenoxyalkanoic acid herbicides in Sphingomonas herbicidovorans MH, were expressed and purified as His6-tagged fusion proteins from Escherichia coli BL21(DE3)(pLysS). RdpA and SdpA belong to subgroup II of the alpha-ketoglutarate-dependent dioxygenases and share the specific motif HXDX(24)TX(131)HX(10)R. Amino acids His-111, Asp-113, and His-270 and amino acids His-102, Asp-104, and His 257 comprise the 2-His-1-carboxylate facial triads and were predicted to be involved in iron binding in RdpA and SdpA, respectively. RdpA exclusively transformed the (R) enantiomers of mecoprop [2-(4-chloro-2-methylphenoxy)propanoic acid] and dichlorprop [2-(2,4-dichlorophenoxy)propanoic acid], whereas SdpA was specific for the (S) enantiomers. The apparent Km values were 99 microM for (R)-mecoprop, 164 microM for (R)-dichlorprop, and 3 microM for alpha-ketoglutarate for RdpA and 132 microM for (S)-mecoprop, 495 microM for (S)-dichlorprop, and 20 microM for alpha-ketoglutarate for SdpA. Both enzymes had high apparent Km values for oxygen; these values were 159 microM for SdpA and >230 microM for RdpA, whose activity was linearly dependent on oxygen at the concentration range measured. Both enzymes had narrow cosubstrate specificity; only 2-oxoadipate was able to replace alpha-ketoglutarate, and the rates were substantially diminished. Ferrous iron was necessary for activity of the enzymes, and other divalent cations could not replace it. Although the results of growth experiments suggest that strain MH harbors a specific 2,4-dichlorophenoxyacetic acid-converting enzyme, tfdA-, tfdAalpha-, or cadAB-like genes were not discovered in a screening analysis in which heterologous hybridization and PCR were used.

Post-collisional Neogene magmatism of the Mediterranean Maghreb margin: a consequence of slab breakoff

A 1 200 km-long linear magmatic belt extends along the Mediterranean coast the Maghreb from Eastern Tunisia to Morocco. This belt is mainly composed of Langan calc-alkaline metaluminous to peraluminous granitoids and associated andesites/cites Central and Eastern Algeria. In Tunisia and Oranie/Western Morocco, calc alkaline activity started later (during the Serravallian) and was followed by the placement of alkali basalts and basanites since the Tortonian to the Pliocene and, in me places, the Pleistocene. Available data on the tectonic setting, petrology, age and biochemistry of this belt show that most of its striking features, e.g. (1) very low magma production rate, subduction-related geochemical imprint, extensive crustal contamination the calc-alkaline magmatism and (2) progressive magmatic change from calc-alkaline alkaline, are consistent with magma generation during a slab breakoff process as proposed Carminati et al, in 1998. The magmatism associated with this breakoff started in Central Eastern Algeria at 16 Ma, then propagated eastwards and westwards, The upward of asthenospheric enriched plume-type mantle through the tear in the downgoing first triggered melting of the overlying lithospheric mantle which had been metasomatised during a previous subduction period. Heat supply from this uprising asthenosphere may have warmed up the continental crust and made its involvement in assimilation processes easier. As the asthenosphere ascended through the `window' in the slab, partial melting occurred at the uprising boundary between asthenosphere and lithosphere, generating basalts with transitional characteristics between those of calc-alkaline and alkaline basalts. As the asthhenospheric upwelling proceeded partial:melting then occurred in the sole asthenospheric mantle, producing alkali basalts.

Imagerie cardiaque non invasive: apport spécifique en clinique des nouvelles modalités (I). Evaluation morphologique [Cardiac imaging: specific clinical role of newly developed non invasive techniques. Part 1: Morphological evaluation].

Echocardiography is the preferred initial test to assess cardiac morphology and ventricular function. Cardiac MRI enables an optimal visualisation of heart muscle without contrast injection, and precise measurement of the ventricular volumes and systolic function. It is therefore an ideal test for patients with poor echocardiographic windows or for the specific evaluation of right heart chambers. Heart CT also remarkably images heart muscle and precisely measures ventricular systolic function after intravenous injection of iodinated contrast. Coronary CT may also, in selected cases, avoid the need for diagnostic coronary angiography. Although very accurate, these imaging modalities are expensive and may be contra-indicated for a particular patient. Their use in clinical practice has to follow the accepted guidelines.

Une question de temps: apprentissage par problème dans un cours de police scientifique

Cet article présente l'évaluation du scénario pédagogique d'un cours portant sur la datation et la chronologie en police scientifique organisé autour d'un apprentissage par problèmes (APP). Ce cours est organisé en APP pour aborder autant les questions pratiques que les concepts théoriques avec les étudiants, remplaçant ainsi une partie d'un enseignement ex cathedra. L'évaluation du scénario a mis en évidence le degré élevé de motivation des étudiants lié aux types de problèmes proposés, issus de situations réelles. Ceux-ci ont appris à travailler en groupe et à interagir de manière systématique avec leur entourage, étant ainsi partenaire de leur apprentissage plutôt que récepteurs. Cette nouvelle façon d'aborder l'enseignement théorique a également permis à l'enseignante d'améliorer ses capacités à transmettre les compétences visées au long du processus mis en place et ceci tout particulièrement en terme de transfert de la théorie vers la pratique.

Activities of daily living with reverse prostheses: importance of scapular compensation for functional mobility of the shoulder.

HYPOTHESIS: The nonanatomical design of reverse shoulder prostheses induce medial displacement of the center of rotation, impingements and may reduce the mobility of the shoulder. The aim of this study is to test the hypothesis that during activities of daily living functional mobility of the shoulder can be restored by scapular compensation. MATERIAL AND METHODS: A numerical 3-dimensional model was developed to reproduce the movement of the scapula and humerus, during 4 activities of daily living measured experimentally. This hypothesis was tested in 4 configurations of the aequalis reverse prosthesis (standard 36-mm glenosphere, 42-mm glenosphere, lateralized 36-mm glenosphere, lateralized Bony Increased-Offset Reverse Shoulder Arthroplasty [BIO-RSA]), which were implanted in the virtual model. All impingement positions were evaluated, as the required scapular compensation to avoid impingements. RESULTS: With the 36-mm glenosphere, impingements occurred only for rest of hand to back-pocket positions. The 42-mm partly improved the mobility. The 2 lateralized glenospheres were free of impingement. When impingements occurred, the scapular compensation was less than 10°. CONCLUSION: Most reverse prostheses impingements reported in clinical and biomechanical studies can be avoided, either by scapular compensation or by a glenosphere lateralization. After reverse shoulder arthroplasty, a fraction of the mobility of the gleno-humeral is transferred to the scapulo-thoracic joint.

"Iatrogenicity cascade": doing harm by treating harm?

An electronic survey on substance-induced epileptic crisis was conducted in order to investigate whether doctors, who recognise their own prescription errors, increase their therapeutic aggressiveness, resulting in a so-called "iatrogenicity cascade". Two pairs of clinical vignettes were constructed, in which a patient suffers from iatrogenic (original version) or non-iatrogenic (control version) epileptic crisis. Vignettes were randomised and sent to doctors at the University Hospital of Lausanne, Switzerland, at an interval of 3 weeks. The results of the present survey in the surveyed population of doctors suggest that inappropriate prescription does not increase therapeutic aggressiveness.

Advance care planning for institutionalised older people: an integrative review of the literature.

BACKGROUND: This integrative review of the literature describes the evolution in knowledge and the paradigm shift that is necessary to switch from advance directives to advance care planning. AIMS AND OBJECTIVES: It presents an analysis of concepts, trends, models and experiments that enables identification of the best treatment strategies, particularly for older people living in nursing homes. DESIGN: Based on 23 articles published between 1999 and 2012, this review distinguishes theoretical from empirical research and presents a classification of studies based on their methodological robustness (descriptive, qualitative, associative or experimental). RESULTS: It thus provides nursing professionals with evidence-based information in the form of a synthetic vision and conceptual framework to support the development of innovative care practices in the end-of-life context. While theoretical work places particular emphasis on the impact of changes in practice on the quality of care received by residents, empirical research highlights the importance of communication between the different persons involved about care preferences at the end of life and the need for agreement between them. CONCLUSIONS: The concept of quality of life and the dimensions and factors that compose it form the basis of Advance care planning (ACP) and enable the identification of the similarities and differences between various actors. They inform professionals of the need to ease off the biomedical approach to consider the attributes prioritised by those concerned, whether patients or families, so as to improve the quality of care at the end of life. IMPLICATIONS FOR PRACTICE: It is particularly recommended that all professionals involved take into account key stakeholders' expectations concerning what is essential at the end of life, to enable enhanced communication and decision-making when faced with this difficult subject.

Epidemiology of biliary tract cancers: an update

BACKGROUND: Biliary tract cancer (BTC) is a rare cancer in Europe and North America, characterized by wide geographic variation, with high incidence in some areas of Latin America and Asia. MATERIALS AND METHODS: BTC mortality and incidence have been updated according to recent data, using joinpoint regression analysis. RESULTS: Since the 1980s, decreasing trends in BTC mortality rates (age-standardized, world standard population) were observed in the European Union as a whole, in Australia, Canada, Hong Kong, Israel, New Zealand, and the United States, and high-risk countries such as Japan and Venezuela. Joinpoint regression analysis indicates that decreasing trends were more favorable over recent calendar periods. High-mortality rates are, however, still evident in central and eastern Europe (4-5/100,000 women), Japan (4/100,000 women), and Chile (16.6/100,000 women). Incidence rates identified other high-risk areas in India (8.5/100,000 women), Korea (5.6/100,000 women), and Shanghai, China (5.2/100,000 women). CONCLUSIONS: The decreasing BTC mortality trends essentially reflect more widespread and earlier adoption of cholecystectomy in several countries, since gallstones are the major risk factor for BTC. There are, however, high-risk areas, mainly from South America and India, where access to gall-bladder surgery remains inadequate.
