Background and Aim: Radiographic sacroiliitis (SI), often asymptomatic, is considered the most frequent extra-intestinal manifestation (EIM) of Crohn's disease (CD). Data on the association of SI with other clinical features of CD are limited. Association of SI with CARD15 polymorphisms has recently been suggested. In a multicenter study, we investigated the association of SI in CD patients with clinical phenotypes, other EIM and CARD15 polymorphisms. Methods: Radiographs of the sacroiliac joints were taken in 251 CD patients from three Belgian university hospitals and scored by two blinded rheumatologists. Clinical features were obtained from medical records. Forty-three percent of patients carried at least one CARD15 polymorphism. Results: Sacroiliitis, defined as the presence of at least grade 2 unilateral changes, was diagnosed in 65 of the 244 scorable radiographs (27%). Only 16 of these patients were previously diagnosed with ankylosing spondylitis (AS). HLA-B27 positivity was observed in 53% of patients with AS and 7% of patients with radiographic SI. In univariate and multivariate analysis, associations between the presence of SI and peripheral arthritis (P = 0.005) and between AS and uveitis (P = 0.005) were found. No associations with other recorded clinical features or with CARD15 polymorphisms were observed. Conclusion: We confirm the high prevalence of radiographic sacroiliitis in a multicenter CD cohort. Uveitis is only associated with AS whereas all patients with SI are more prone to develop peripheral arthritis during their disease course, suggesting similar pathogenetic mechanisms in the development of these EIM. The previously reported association between SI and CARD15 polymorphisms was not confirmed. [less ▲]

Le tractus gastro-intestinal joue un rôle important dans l'homéostasie des protéines plasmatiques, aussi bien chez le sujet normal que dans les états pathologiques. A l'état physiologique, les protéines présentes dans la lumière intestinale ont une double origine: exogène, constituée des protéines alimentaires, et endogène, provenant des sécrétions digestives, de la desquamation cellulaire et des protéines plasmatiques sécrétées ou exsudées. L'exagération de ce dernier mécanisme définit l'entéropathie exsudative qu'il est plus logique de dénommer gastroentéropathie exsudative ou gastroentéropathie avec pertes de protéines dans la mesure où l'estomac peut participer à t'exsudation et que les pertes portent surtout sur les protéines normalement présentes dans le sang, la lymphe et le liquide interstitel. Citrin et coll. [26] ont été les premiers, en 1957, à mettre en évidence une déperdition d'albumine marquée a l'iode 131 chez un malade présentant une maladie de Ménétrier. Le terme d'entéropathie exsudative (<< protein-losing enteropathy ») a été utilisé pour la première fois en 1959 par Gordon aux Etats-Unis et Schwartz et Jarnum au Danemark. En France, c'est à Cattan et Vésin r2~] que l'on doit les premiers travaux consacrés à cette entité. Il s'agit en fait d'un syndrome relevant de causes multiples. Dans la majorité des cas, les manifestations cliniques et biologiques de l'exsudation sont au second plan, masquées par l'affection en cause. Le diagnostic est plus rarement évoqué devant une hypoprotidémie avec ou sans syndrome oedémateux non expliquée par une origine hépatique ou rénale. [less ▲]

Because of the lack of clinical data in the area, this clinical study was performed to evaluate gastrointestinal prokinetics’ efficiency. Material used includes 2 groups composed each one by 25 horses which underwent surgery for small intestinal lesions in the University of Liège between january 1997 and august 2005. The 2 groups were formed by a selection resulting in similar (or not significantly different) mean values for the age, gravity score, shock score, packed cell volume on admission in the clinic and length of resected intestine when an enterectomy was performed. Between the 2 groups, we searched also equal (or not significantly different) proportions of Belgian Warmblood, of females/males, of horses wich underwent an enterectomy, of horses which had a concomitant lesion of the large intestine and of horses wich needed 1 or more sedative α2 agonist drug during the postoperative period. One group was treated with gastrointestinal prokinetics (lidocaine, erythromycin, metoclopramide) systematically, whereas the other one not and the incidence and duration of postoperative ileus was evaluated. No significant difference in the incidence or the duration of postoperative ileus was found between the 2 groups. Because our results did not show any effect of prokinetics, a statistical analysis searched in these 50 horses the risk factors of postoperative ileus among the following parameters: breed, age, sex, gravity score, shock score, packed cell volume on admission in the clinic, protocol of induction of anaesthesia, duration of anaesthesia, performing an enterectomy and length of the resected intestine, concomitant lesion of the large intestine, and administration of sedative α2 agonists during the postoperative period. Only the Belgian warmblood breed and the administration of sedative α2 agonist drugs after the recovery from anaesthesia were significantly more important in the group where horses developed a postoperative ileus. Undoubdtedly, this study includes only 50 cases selected for the homogeneity of their parameters and not all the cases of small intestine surgery during the test period. In view of these results, it would be interesting performing this study again on a larger number of cases in a prospective manner. [less ▲]

OBJECTIVES: Selective inhibitors of cyclo-oxygenase-2 (COX-2) appear to be safer than conventional NSAIDs on the gastrointestinal (GI) tract. Amtolmetin guacyl (AMG), a NSAID that inhibits both COX-1 and COX-2, has an anti-inflammatory effect comparable to that of traditional NSAIDs, with a better GI safety profile. The primary end-point of this study was to evaluate the gastrointestinal safety of amtolmetin guacyl in comparison with celecoxib in patients affected with rheumatoid arthritis. The assessment of efficacy was the secondary end-point. [less ▲]

When a granular material is driven in microgravity environment, one can assist to the formation of dense and slow regions in the system. Indeed, given the dissipative character of the collisions in the media, energy is lost at each particle interaction and the grains begin to clump locally. The phenomenon has been observed for the first time in the late nineties during sounding rocket experimentation by Falcon and his coworkers and has attracted the interest of many scientists since then. However, precise laws describing the formation and the dynamics of such clusters are still lacking. In order to allow an intensive study of the phenomenon, the European Space Agency set up the SpaceGrains project. Small bronze spheres are enclosed in a rectangular cell and vertically driven by to pistons oscillating in phase opposition. Our work consists in the preparation of the SpaceGrains experiment via molecular dynamics simulations and the elaboration of models predicting the behaviour of the system. Before we started our study concerning SpaceGrains, we reproduced and extended Falcon’s sounding rocket experiments. We showed that, in addition to the granular gas and the cluster, another dynamical regime can be observed in the system. Indeed, for higher filling fractions, the entire granular media behaves like one single completely dissipative particle called the bouncing aggregate. Bouncing modes are observed and can be explained considering the bouncing ball paradigm. Moreover, we highlighted the role of the packing fraction φ as well as the size of the particles R on the different observed dynamics. Within the frame of the SpaceGrains device, we studied the impact of all tunable parameters of the experiment on the dynamics of the system. Thanks to an appropriate scaling all transition points that we obtained by varying the driving amplitude A, the packing fraction and the dimen- sions of the cell L fall along a same theoretical curve. The latter is explained regarding the energy transfer from the piston towards the center of the cell. Once the clustering was controlled, we investigated the handling of the agglomerate. By compartmentalizing the container, local trapping can be achieved and a granular pendant of Maxwell’s demon can be observed in microgravity. Based on the measured particle flux between the compartments, we realized a theoretical model predicting the asymptotic steady state of the system depending on the total number N of particles. In a clustered system, we investigated the impact of asymmetrical driving on the system’s dy- namics. We showed that the mean position of the cluster can be fully controlled via the amplitude ratio a. Moreover, the natural fluctuations of the agglomerate around its equilibrium position are dictated by the driving frequency f and the mass of the cluster. Finally, we realized simulations of driven bi-disperse gases and investigated the segregation phenomena in the system. We showed that clustering and segregation are strongly linked and that the size and the mass of the particles impact the segregation dynamics in different ways. [less ▲]

The paper examines poll survey data to see if the way people invest in public envolvement is different between thos consider themselves to the left and those who consider themselves to the right. It appears that the difference beween rightl and left is small and that the main difference is bewteen those who choose a position and those who refuse to choose or do not answer. Rather interestingly, people that see themselves at the center ressembles strongly to non respondants, as if the center was a "refuge value". [less ▲]

Gaucher disease is a relatively rare metabolic disease caused by the inherited deficiency of the lysosomal enzyme glucocerebrosidase. Gaucher disease affects multiple organs, among which is the skeleton. Bone involvement occurs frequently in Gaucher disease, and is one of its most debilitating features, reducing the quality of life of patients. Bone status is an important consideration for treatment to ameliorate symptoms and reduce the risk of irreversible complications. We have conducted a systematic review of all the various aspects of Gaucher disease, focusing on different skeletal manifestations, pathophysiology of bone alterations, clinical symptoms, and current diagnostic and therapeutic approaches.

We present an automated tool for measuring atmospheric parameters (T_eff, log(g), [Fe/H]) for F-G-K dwarf and giant stars. The tool, called GAUFRE, is written in C++ and composed of several routines: GAUFRE-RV measures radial velocity from spectra via cross-correlation against a synthetic template, GAUFRE-EW measures atmospheric parameters through the classic line-by-line technique and GAUFRE-CHI2 performs a chi^2 fitting to a library of synthetic spectra. A set of F-G-K stars extensively studied in the literature were used as a benchmark for the program: their high signal-to-noise and high resolution spectra were analysed by using GAUFRE and results were compared with those present in literature. The tool is also implemented in order to perform the spectral analysis after fixing the surface gravity (log(g)) to the accurate value provided by asteroseismology. A set of CoRoT stars, belonging to LRc01 and LRa01 fields was used for first testing the performances and the behaviour of the program when using the seismic log(g). [less ▲]

We revisit the gauge-covariant canonical formalism by separating explicitly physical and gauge degrees of freedom. We show in particular that the gauge-invariant linear and angular momentum operators proposed by Chen et al. can consistently be derived from the standard procedure based on Noether’s theorem. Finally, we demonstrate that this approach is essentially equivalent to the gauge-invariant canonical formalism based on the concept of Dirac variables. Because of many similarities with the background field method, the formalism developed here should also be relevant to general relativity and any metric theories. [less ▲]

Belgium is one of the first European country to legalize marriage and adoption for same-sex couples (respectively in 2003 and 2006) and to state anti-discrimination laws (2008). Despite the legalization, what can we say about adults’ attitudes? This study is part of an international project, and aims at studying the attitudes towards different kind of same-sex constellations – single gays and lesbians, couples, and families – and at examining the correlates to those attitudes. Attitudes were assessed through self-report questionnaires in a cohort of 366 heterosexual participants resident in Belgium, 72% females and 28% males aged from 26 to 40 (age class corresponding to transition lifecycle and parenting choices). Participants were asked to answer socio-demographic questions and to self-report their contact with homosexual people (frequency and satisfaction). Then different scales assessed their attitudes toward homosexuality (General Attitudes Toward Homosexuality, Da Costa, 2011; ATLG, Herek), same-sex marriage (Katuzny Scale on Same-Sex Marriage, 2012) and different types of same¬-sex parenting – adoption, alternative insemination, in vitro, ovocyte donation (D’Amore & Green Homoparentality Scale, 2012). It is hypothesized that correlates to positive attitudes will be associated with female gender, lower religiosity, non-protestant religions, liberal political ideology, and higher education and socioeconomic status. This presentation contributes to a better understanding of Belgian’s attitudes toward same-sex couples and same-sex families, by measuring the predictive variables of positive and negative attitudes.
