    Abstract: Ce travail revoit les cas d'abcÚs cérébraux rencontrés dans le centre hospitalier universitaire vaudois (CHUV) ces derniÚres dix années. La période étudiée débute en janvier 2000 et se termine en septembre 2010. Elle comprend 65 cas d'abcÚs cérébraux diagnostiqués par IRM. Cette revue a pour but d'avoir une documentation de l'épidémiologie et des caractéristiques IRM des différents types d'abcÚs cérébraux étudiés. Introduction: L'abcÚs cérébral est une pathologie grave et potentiellement létale, qui peut laisser le patient sévÚrement handicapé. La prise en charge de ces patients, a énormément évolué depuis l'arrivée de l'antibiothérapie et leur diagnostic a été nettement amélioré ces 30 derniÚres années depuis l'introduction, de plus en plus systématique, soit de la tomographie computérisée (CT/scanner), soit de l'imagerie par résonance magnétique (IRM). Tous ces progrÚs, combiné aux avancées des diverses techniques neurochirurgicales ont permis d'améliorer nettement le pronostic de ces patients.

It has repeatedly been shown that despite awareness of guidelines and prescription of the recommended amounts of energy (25 kcal/kg), underfeeding remains a prominent problem worldwide. In patients with prolonged stays, overfeeding has also become an issue. This lack of fit between prescription and delivery is largely caused by the lack of visibility of the nutritional results to nurses and clinicians. Computerized systems have brought major improvements, mainly through the customization of nutrition relevant variables in a single place, making them visible. Another important point is the possibility to change the ICU time constant to days and weeks which is the delay relevant for nutritional changes to appear, instead of minutes and hours which are more relevant for critical care

    Weyl formulas for annular ray-splitting billiards

    Full text link
    We consider the distribution of eigenvalues for the wave equation in annular (electromagnetic or acoustic) ray-splitting billiards. These systems are interesting in that the derivation of the associated smoothed spectral counting function can be considered as a canonical problem. This is achieved by extending a formalism developed by Berry and Howls for ordinary (without ray-splitting) billiards. Our results are confirmed by numerical computations and permit us to infer a set of rules useful in order to obtain Weyl formulas for more general ray-splitting billiards

    Effects of the microenvironment surrounding Cys433 in Arabidopsis ÎČ-amylase-1 and -3 on the sensitivity to glutathionylation by nitrosoglutathione

    Glutathionylation is a reversible post-translational modification of proteins involving the transfer of glutathione to the thiols of specific cysteine residues. While the mechanism behind glutathionylation is known, the specificity of cysteine glutathionylation is not understood. It is known, however, that the two main factors affecting the susceptibility to glutathionylation are the reactivity and accessibility of cysteines in proteins, which is determined by the microenvironment. Using ÎČ-amylases (BAMs) 1 and 3 from Arabidopsis thaliana, which have different sensitivities to nitrosoglutathione (GSNO), as a model, I attempted to provide insight into why some cysteines are glutathionylated by GSNO and others are not. Our lab found that GSNO inhibits BAM3 activity by glutathionylating Cys433 in vitro, yet BAM1 is unaffected by GSNO despite containing a cysteine at the same position. At a physiological level, the glutathionylation of BAM3 by GSNO may be important as BAM3 may be inhibited by a NO-induced modification under cold stress. Different microenvironments surrounding Cys433 in BAM1 and BAM3 could explain the different sensitivities these enzymes have to GSNO. I compared sequence alignments of BAM1 and BAM3 from a variety of flowering plants. If a position is important in making Cys433 in BAM3 and BAM1 sensitive and insensitive, respectively, to GSNO, then that position would likely be conserved within each BAM1 and BAM3 orthologous set but be different between the sets. After comparing sequence alignments and locating these positions in homology models, I hypothesized that H430, N432, and S434 might contribute to the sensitivity of Cys433 in BAM3 to GSNO, and that the corresponding amino acids in BAM1, D430, L432, and A434, might contribute to its insensitivity. To test this hypothesis, I made three BAM3 mutants with the amino acid substitution H430D, N432L, or S434A and the corresponding BAM1 mutants, D430H, L432N, and A434S. All of the BAM1 mutants were active but only the BAM3 mutant with the H430D substitution was active. I then treated the active mutants with GSNO and compared their sensitivity to the BAM3 and BAM1 controls. The BAM1-D430H and BAM1-A434S mutants were inhibited by 45% and 20%, respectively, by GSNO whereas the WT BAM1 control was insensitive to GSNO. The active BAM3 mutant, however, was just as sensitive to GSNO as the BAM3 control. Therefore, D430 and A434 may contribute to the insensitivity of Cys433 to glutathionylation by GSNO in BAM1. D430 may play a larger role in making Cys433 insensitive to GSNO in BAM1 than A434 because it is negatively charged, which could decrease the reactivity and/or the accessibility of Cys433

    How can we measure the causal effects of social networks using observational data? Evidence from the diffusion of family planning and AIDS worries in South Nyanza District, Kenya

    Get PDF
    This study presents estimates that social networks exert causal and substantial influences on individuals’ attitudes and behaviors. The study explicitly allows for the possibility that social networks are not chosen randomly, but rather that important characteristics such as unobserved preferences and unobserved community characteristics determine not only the outcomes of interest but also the informal conversational networks in which they are discussed. Longitudinal survey data from rural Kenya on family-planning and AIDS are used to estimate the impact of social networks while controlling for their unobserved determinants. There are four major findings: First, the endogeneity of social networks can substantially distort the usual cross-sectional estimates of network influences. Second, social networks have significant and substantial effects even after controlling for unobserved factors that may determine the nature of the social networks. Third, these network effects generally are nonlinear and asymmetric. In particular, they are relatively large for individuals who have at least one network partner who is perceived to be using contraceptives or or to be at high risk of HIV/AIDS, which is consistent with S-shaped diffusion models that have been emphasized in the literature. Fourth, the effects of networks are not confined to the use of family planning by women, the focus of much of the literature on networks in demography, but appear to be more general, influencing responses to HIV/AIDS, and influencing men as well as women.

    A summary of Special Collection 1

    Get PDF
    Special Collection 1: Social Interactions and HIV/AIDS in Rural Africa is a set of papers stemming from the conference "Research on Demographic Aspects of HIV/AIDS in Rural Africa", held at the Population Studies Center, University of Pennsylvania, October 28, 2002. The aim of the conference was to provide a forum for the presentation of results, to an audience of experts, on a variety of demographic aspects relevant for the study of HIV/AIDS in rural Africa. The aim of the special collection is to make these results available to a wider audience. Thirteen contributions were submitted to the journal Demographic Research and went through peer review. They were published on September 19, 2003 as the journal’s first ñ€Ɠspecial collectionñ€ of material on a common topic. This short summary of the collection has been added to Volume 9 in order to include full details of the collection in the current running volume as well. The following pages list the contributions and give direct links where readers may download the material from the Demographic Research website. A full list of all papers is also available at: http://www.demographic-research.org/special/1/.AIDS/HIV, Kenya, Malawi
