Le cours de Médecine Palliative est organisé en avant-dernière année des études médicales de 2e cycle par deux enseignants, Médecin Généraliste et Médecin Hospitalier. Ce cours a été dispensé pendant 10 ans selon un format traditionnel ex cathedra. Il était dispensé par de nombreux intervenants pluridisciplinaires. Une évaluation des enseignements a montré que les étudiants jugeaient les interventions trop théoriques, sans lien avec leurs questions et préoccupations. En conséquence, c’est la discipline « Médecine Palliative et de Soins de Vie » qui ne suscitaient pas d’intérêt. De nouveaux objectifs et de nouvelles modalités pédagogiques ont été introduits en 2010-2011 à l’attention de 100 étudiants. L’objectif principal est le développement chez les étudiants d’une attitude réflexive face à la discipline « Médecine Palliative ». Les outils pédagogiques introduits dans le dispositif sont le portfolio électronique, une vignette clinique évolutive, l’accompagnement à distance de chaque étudiant par un tuteur, des cours en présentiel. La pratique réflexive de chaque étudiant est évaluée au terme du dispositif, conjointement par les 2 enseignants sur base de critères et d’indicateurs. Voici une illustration des critères utilisés : - Intensité des interactions dans le carnet d’apprentissage électronique (et aux cours) - Pertinence des interventions - Engagement dans la tâche - Capacité réflexive (pertinence de l’analyse et de la régulation de la situation décrite dans la vignette) - Qualité de l’auto-évaluation et identification des éléments déclencheurs de progrès - Degré d’apprentissage (Bilan d’atteinte des objectifs fixés par le cours et décrits) La communication orale présentera le dispositif d’évaluation, les critères et les indicateurs utilisés, les premiers résultats de l’évaluation des étudiants, les perspectives de régulation du dispositif d’évaluation.

The present study investigates the combined effect of phosphorous limitation, elevated partial pressure of CO2 (pCO2) and temperature on a calcifying strain of Emiliania huxleyi (PML B92/11) by means of a fully controlled continuous culture facility. Two levels of phosphorous limitation were consecutively applied by renewal of culture media (N:P = 26) at dilution rates (D) of 0.3 d− 1 and 0.1 d− 1. CO2 and temperature conditions were 300, 550 and 900 μatm pCO2 at 14 °C and 900 μatm pCO2 at 18 °C. In general, the steady state cell density and particulate organic carbon (POC) production increased with pCO2, yielding significantly higher concentrations in cultures grown at 900 μatm pCO2 compared to 300 and 550 μatm pCO2. At 900 μatm pCO2, elevation of temperature as expected for a greenhouse ocean, further increased cell densities and POC concentrations. In contrast to POC concentration, C-quotas (pmol C cell− 1) were similar at D = 0.3 d− 1 in all cultures. At D = 0.1 d− 1, a reduction of C-quotas by up to 15% was observed in the 900 μatm pCO2 at 18 °C culture. As a result of growth rate reduction, POC:PON:POP ratios deviated strongly from the Redfield ratio, primarily due to an increase in POC. Ratios of particulate inorganic and organic carbon (PIC:POC) ranged from 0.14 to 0.18 at D = 0.3 d− 1, and from 0.11 to 0.17 at D = 0.1 d− 1, with variations primarily induced by the changes in POC. At D = 0.1 d− 1, cell volume was reduced by up to 22% in cultures grown at 900 μatm pCO2. Our results indicate that changes in pCO2, temperature and phosphorus supply affect cell density, POC concentration and size of E. huxleyi (PML B92/11) to varying degrees, and will likely impact bloom development as well as biogeochemical cycling in a greenhouse ocean.

En Afrique Subsaharienne, les taux d’adhésion aux mutuelles de santé restent généralement à des niveaux très faibles. Cet article vise à synthétiser les résultats des enquêtes déjà réalisées pour identifier les facteurs qui influencent la décision d’adhérer ou non à ces mutuelles. Au-delà des différences méthodologiques entre ces travaux, notre synthèse fait ressortir deux facteurs majeurs qui étaient plutôt attendus (la capacité financière des populations et la qualité des soins) et les resitue dans une perspective plus large. Elle permet également d’identifier quelques autres paramètres qui semblent aussi jouer un rôle significatif même si les convergences entre les enquêtes sont moins nettes. [less ▲]

Diastematomyelia is a relatively rare congenital abnormality presenting as a sagittal separation of the spinal cord. Although cases of diastematomyelia have been previously reported, fully documented approaches by both prenatal and postnatal diagnostic workup are rare in the literature. We present a fully studied case of diastematomyelia type I investigated by prenatal US and MRI and postnatal US, MRI and radiography. [less ▲]

beta-Lactam antibiotics have long been a treatment of choice for bacterial infections since they bind irreversibly to Penicillin-Binding Proteins (PBPs), enzymes that are vital for cell wall biosynthesis. Many pathogens express drug-insensitive PBPs rendering beta-lactams ineffective, revealing a need for new types of PBP inhibitors active against resistant strains. We have identified alkyl boronic acids that are active against pathogens including methicillin-resistant S. aureus (MRSA). The crystal structures of PBP1b complexed to 11 different alkyl boronates demonstrate that in vivo efficacy correlates with the mode of inhibitor side chain binding. Staphylococcal membrane analyses reveal that the most potent alkyl boronate targets PBP1, an autolysis system regulator, and PBP2a, a low beta-lactam affinity enzyme. This work demonstrates the potential of boronate-based PBP inhibitors for circumventing beta-lactam resistance and opens avenues for the development of novel antibiotics that target Gram-positive pathogens.

As atmospheric pollution is causing several environmental problems it is incumbent to reduce the impact of pollution on the environment. One particular problem is the production of CO2 by many transport and industrial applications. Instead of stocking CO2 and instead of being a product, it can be used as a source. The case considered is the CO2 reformation of methane producing hydrogen and CO. It is an endothermic reaction, for which the activation barrier needs to be surpassed. This can be done efficiently by the method of Dielectric Barrier Discharge. The process relies on the collision of electrons, which are accelerated under an electrical field that is created in the discharge area. This leads to the formation of reactive species, which facilitate the abovementioned reaction. This study is performed using a Matlab program with the Reaction Engineering module in COMSOL (with an incorporated kinetic mechanism) in order to model the discharge phase. Then COMSOL (continuity and Navier-Stokes equations) is used to model the flow in the post-discharge phase. The results showed that both a 2D and 3D model can be used to model the chemical-plasma process. These methods need strongly reduced kinetic mechanism, which in some cases can cause loss of precision. [less ▲]
