Scores composites CHC pour la WAIS-IV : normes francophones

Les résultats des recherches contemporaines, montrant notamment l'importance du raisonnement fluide, de la mémoire de travail (IMT) et de la vitesse de traitement (IVT) dans le fonctionnement cognitif, ont conduit les concepteurs de la WAIS-IV à introduire de nouvelles épreuves pour renforcer l'évaluation de ces dimensions cognitives. L'interprétation des scores de la WAIS-IV repose maintenant sur quatre indices factoriels (ICV, IRP, IMT et IVT), ainsi que sur le QIT. Les concepteurs de la WAIS-IV indiquent que l'un des objectifs de la révision consistait à actualiser les fondements théoriques de cette échelle. Pourtant, la structure globale de la WAIS-IV ne correspond que partiellement à celle proposée dans le modèle qui fait consensus aujourd'hui, le modèle de Cattell-Horn-Carroll (CHC). Par exemple, la WAIS-IV ne propose pas d'indice de raisonnement fluide, bien que les constructeurs soulignent l'importance de cette dimension dans le fonctionnement cognitif. Dans cet article, nous proposons, pour la WAIS-IV, les normes francophones de cinq scores composites CHC, à savoir le raisonnement fluide (Gf), compréhension-connaissances (Gc), le traitement visuel (Gv), la mémoire à court terme (Gsm), et l'IVT (Gs). Ces normes ont été établies en utilisant une procédure d'approximation statistique. À l'instar des scores CHC que nous avons proposés pour le WISCIV, ces normes pour la WAIS-IV permettent aux cliniciens de basculer vers une grille d'interprétation basée sur le modèle dominant et d'utiliser les cinq scores composites CHC en complément des quatre indices standard dans le cadre d'analyses normatives et ipsatives.

O papel da família e da pertença a redes sociais na construção de trajectórias educativas e sociais de nível superior

A decisão de sair do país para realizar estudos superiores é, no contexto dos novos países africanos, cada vez mais uma decisão individual, e/ou de famílias, dado o enfraquecimento do papel regulador do Estado na situação actual de liberalização económica e consequente crescente “individualização. A partir de uma série de entrevistas a estudantes universitários angolanos, a estudar em Portugal realizadas em Lisboa e no Porto, e a profissionais que estudaram no ensino superior português, em Luanda, procurar-se-á aferir o lugar ocupado pelas “redes sociais” construídas, e mantidas, em torno de relações familiares alargadas, assim como de relações académicas ou outras, e a sua repercussão na consolidação de redes sociais mais amplas (como as que ligam estes formandos ao país de formação, e as que ligam este país ao seu país de origem) com implicações na cooperação entre os dois países e, mais concretamente, no desenvolvimento de Angola.

Clinical Proton MR Spectroscopy in Central Nervous System Disorders.

A large body of published work shows that proton (hydrogen 1 [(1)H]) magnetic resonance (MR) spectroscopy has evolved from a research tool into a clinical neuroimaging modality. Herein, the authors present a summary of brain disorders in which MR spectroscopy has an impact on patient management, together with a critical consideration of common data acquisition and processing procedures. The article documents the impact of (1)H MR spectroscopy in the clinical evaluation of disorders of the central nervous system. The clinical usefulness of (1)H MR spectroscopy has been established for brain neoplasms, neonatal and pediatric disorders (hypoxia-ischemia, inherited metabolic diseases, and traumatic brain injury), demyelinating disorders, and infectious brain lesions. The growing list of disorders for which (1)H MR spectroscopy may contribute to patient management extends to neurodegenerative diseases, epilepsy, and stroke. To facilitate expanded clinical acceptance and standardization of MR spectroscopy methodology, guidelines are provided for data acquisition and analysis, quality assessment, and interpretation. Finally, the authors offer recommendations to expedite the use of robust MR spectroscopy methodology in the clinical setting, including incorporation of technical advances on clinical units. © RSNA, 2014 Online supplemental material is available for this article.

Chirurgie bariatrique en 2013: principes, avantages et inconvénients des interventions a disposition [Bariatric surgery in 2013: principles, advantages and disadvantages of the available procedures].

For severe obesity (BMI > 35 kg/m2), bariatric surgery is not only the best, but often the only means of obtaining sufficient and durable weight loss. This article aims to review the available bariatric procedures. Gastric bypass remains the reference when it comes to the risk/benefit ratio. Gastric banding is declining rapidly due to the high prevalence of long-term complications. Primary malabsorptive procedures remain largely unpopular because of their potential nutritional complications. Sleeve gastrectomy, although it is not reversible as it includes a significant gastric resection, increases currently in popularity because of its apparent simplicity and the fact that early results regarding weight loss mimic those obtained with gastric bypass.

Competitive location and pricing on networks

In this paper we consider a location and pricing model for a retail firm that wants to enter a spatial market where a competitor firm is already operating as a monopoly with several outlets. The entering firms seeks to determine the optimal uniform mill price and its servers' locations that maximizes profits given the reaction in price of the competitor firm to its entrance. A tabu search procedure is presentedto solve the model together with computational experience.

Combined analysis of grey matter voxel-based morphometry and white matter tract-based spatial statistics in late-life bipolar disorder.

Background: Previous magnetic resonance imaging (MRI) studies in young patients with bipolar disorder indicated the presence of grey matter concentration changes as well as microstructural alterations in white matter in various neocortical areas and the corpus callosum. Whether these structural changes are also present in elderly patients with bipolar disorder with long-lasting clinical evolution remains unclear. Methods: We performed a prospective MRI study of consecutive elderly, euthymic patients with bipolar disorder and healthy, elderly controls. We conducted a voxel-based morphometry (VBM) analysis and a tract-based spatial statistics (TBSS) analysis to assess fractional anisotropy and longitudinal, radial and mean diffusivity derived by diffusion tensor imaging (DTI). Results: We included 19 patients with bipolar disorder and 47 controls in our study. Fractional anisotropy was the most sensitive DTI marker and decreased significantly in the ventral part of the corpus callosum in patients with bipolar disorder. Longitudinal, radial and mean diffusivity showed no significant between-group differences. Grey matter concentration was reduced in patients with bipolar disorder in the right anterior insula, head of the caudate nucleus, nucleus accumbens, ventral putamen and frontal orbital cortex. Conversely, there was no grey matter concentration or fractional anisotropy increase in any brain region in patients with bipolar disorder compared with controls. Limitations: The major limitation of our study is the small number of patients with bipolar disorder. Conclusion: Our data document the concomitant presence of grey matter concentration decreases in the anterior limbic areas and the reduced fibre tract coherence in the corpus callosum of elderly patients with long-lasting bipolar disorder.
