Le diagnostic et la prise en charge thérapeutique du cancer deviennent extrêmement complexes. La concertation oncologique multidisciplinaire (COM) permet d’optimiser la prise en charge du patient atteint de cancer. La COM permet de confronter les différents points de vue de chaque intervenant afin que le plan thérapeutique soit réellement l’approche la plus prometteuse et rationnelle pour traiter le cancer et, dans un contexte de maladie incurable, pour favoriser au mieux la qualité de vie. Cependant, le patient a toujours le dernier mot. Il peut évidemment refuser pour des raisons personnelles le traitement optimal. [less ▲]

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 ▲]

OBJECTIVES: The objective of this study was to compare ecological and recalled pain intensity assessments over 29 days in hip and knee osteoarthritis (O) and chronic low back pain (L). PATIENTS AND METHODS: Rheumatologists were asked to enroll patients with O and L, with pain intensity above 40 mm, in a prospective study for 29 days. Pain intensity was assessed with physicians on Days 1 and 29, and ecologically, over the intervening 28-day period, by random phone calls. RESULTS: We carried out correlation analyses for 353 (159 O, 194 L) patients: Overall recalled daily pain was strongly correlated with calculated 3-day mean pain assessments (r=0.96 [O]; 0.93 [L]) and evening pain (r=0.96 [O], 0.90 [L]). Correlations between ecological and recalled measures were stronger for recall over the last 7 days than for recall over the last 28 days in osteoarthritis patients (r=0.78, r=0.63), but were similar for both recall periods in low back pain patients (r=0.70, r=0.72). Correlations between assessments for the last 7 and 28 days were stronger for ecological (r=0.88 [O], 0.91 [L]) than for clinical (r=0.77 [O]; 0.86 [L]) assessments. After adjustment for current pain intensity, correlations remained significant for ecological assessments, but not for clinical assessments. Recalled pain assessments were more accurate when made after 24 hours (r=0.71 [O]; 0.70 [L]) than when made after 48 hours (r=0.63 [O]; 0.61 [L]). CONCLUSIONS: For both low back pain and osteoarthritis, overall daily pain recall is a reliable measurement correlated with daily ecological measurements, whereas a rapid decrease in recall occurs after 48 hours. The most reliable period for pain recall was 7 days, but the results obtained were influenced by current pain. [less ▲]

X-ray microtomography coupled to image analysis has been used to study the influence of the adsorbent pore texture and the experimental conditions on the dynamic adsorption of methyl iodide in packed filters. By applying this imaging technique the internal axial adsorption profiles for increasing exposure times to the gas stream are analysed. This experimental technique establishes a new technology to study in situ the dynamic adsorption of volatile compounds. Resorcinol-formaldehyde based carbon xerogels have been used as adsorbents, as their pore texture can be tuned by changing the synthesis conditions. The textural characteristics of the adsorbents (surface areas and pore volumes) have been assessed by using nitrogen and carbon dioxide adsorption as well as mercury porosimetry. The methyl iodide dynamic adsorption results show that, for the same gas flow rate and CH3I inlet concentration, the adsorbed amount is highly dependent on large pore volumes. Thus, samples with almost the same micropore volumes (adsorption volumes) have different methyl iodide adsorption capacities, which are related to, the above mentioned, large pores. The influence of both the gas carrier flow rate and the methyl iodide inlet concentration on the adsorption can be explained using the so-called linear driving force model. This approach takes into account the fact that internal transport limitations are directly related to the pore texture. Moreover, the simulation of the dynamic adsorption process has allowed relating the simulated axial concentration profiles to the experimental X-ray microtomography data. [less ▲]

Intraventricular hemorrhage is common after the rupture of anterior communicating artery (ACoA) aneurysms, although the anatomical pathway has not been described. Knowledge of the mechanism of hemorrhage may enhance understanding of its prognosis. Using CT angiography, the authors analyzed this pathway in 2 cases of ACoA aneurysm rupture associated with intraventricular hemorrhage. The initial hemorrhages created a hyperdense ventriculographic image on which the subsequent contrast medium ejection could be followed. The contrast medium entered the subarachnoid space of the anterior interhemispheric fissure and broke through the lamina rostralis into the septum pellucidum and into the frontal horns of the lateral ventricles. Thus, the authors provide an explanation for bleeding from ACoA aneurysms into the ventricular system in the presence of an intact lamina terminalis. The septum pellucidum may act as a buffer before extension of the bleeding into the ventricular system. [less ▲]

Transverse-momentum dependent parton distributions (TMDs) are studied in the framework of quark models. In particular, quark-model relations among TMDs are reviewed, elucidating their physical origin in terms of the quark-spin structure in the nucleon. The formal aspects of the derivation of these relations are complemented with explicit examples, emphasizing how and to which extent the conditions which lead to relations among TMDs are implemented in different classes of quark models.

ABSTRACT: BACKGROUND: Abdominal aortic aneurysm (AAA) is a complex disorder with multiple genetic risk factors. Using affected relative pair linkage analysis, we previously identified an AAA susceptibility locus on chromosome 19q13. This locus has been designated as the AAA1 susceptibility locus in the Online Mendelian Inheritance in Man (OMIM) database. METHODS: Nine candidate genes were selected from the AAA1 locus based on their function, as well as mRNA expression levels in the aorta. A sample of 394 cases and 419 controls was genotyped for 41 SNPs located in or around the selected nine candidate genes using the Illumina GoldenGate platform. Single marker and haplotype analyses were performed. Three genes (CEBPG, PEPD and CD22) were selected for DNA sequencing based on the association study results, and exonic regions were analyzed. Immunohistochemical staining of aortic tissue sections from AAA and control individuals was carried out for the CD22 and PEPD proteins with specific antibodies. RESULTS: Several SNPs were nominally associated with AAA (p < 0.05). The SNPs with most significant p-values were located near the CCAAT enhancer binding protein (CEBPG), peptidase D (PEPD), and CD22. Haplotype analysis found a nominally associated 5-SNP haplotype in the CEBPG/PEPD locus, as well as a nominally associated 2-SNP haplotype in the CD22 locus. DNA sequencing of the coding regions revealed no variation in CEBPG. Seven sequence variants were identified in PEPD, including three not present in the NCBI SNP (dbSNP) database. Sequencing of all 14 exons of CD22 identified 20 sequence variants, five of which were in the coding region and six were in the 3'-untranslated region. Five variants were not present in dbSNP. Immunohistochemical staining for CD22 revealed protein expression in lymphocytes present in the aneurysmal aortic wall only and no detectable expression in control aorta. PEPD protein was expressed in fibroblasts and myofibroblasts in the media-adventitia border in both aneurysmal and non-aneurysmal tissue samples. CONCLUSIONS: Association testing of the functional positional candidate genes on the AAA1 locus on chromosome 19q13 demonstrated nominal association in three genes. PEPD and CD22 were considered the most promising candidate genes for altering AAA risk, based on gene function, association evidence, gene expression, and protein expression. [less ▲]
