We studied 622 transplants undertaken between 1982 and 2001 to: (1) determine the incidence, timing and etiology of bacteremias, and (2) examine the ability of routine surveillance cultures to predict bacteremias. A total of 404 episodes (0.65 episode per patient) occurred in 248 patients, due to coagulase-negative staphylococci (n=171, 42%), Gram-negative bacteria (n=129, 32%), streptococci (n=48, 12%), other Gram-positive bacteria (n=33, 8%), anaerobes (n=9, 2%) and fungi (n=14, 3%). Bacteremias were more frequent in allogeneic (0.96 episode/patient) compared to autologous (0.44) transplants (P<0.0001). The overall incidence decreased from 0.92 episode/patient until 1990 to 0.66 in 1991-1996 and 0.55 in 1997-2001 (P<0.0001), but this was only observed in autologous transplants. Among them, 212 (53%) occurred before hospital discharge and 192 (47%) thereafter. This proportion was lower for coagulase-negative staphylococci, other Gram-positive bacteria and Gram-negative bacteria compared to other agents (P=0.001). In 50% of the cases, the agent responsible for the bacteremic episode was present in routine surveillance cultures previously. In conclusion: (1) bacteremias remain a frequent complication, particularly in allogeneic transplantation, even long after hospital discharge; (2) routine surveillance cultures can predict bacteremias in 50% of the cases, but the practical impact of this observation is limited in view of the costs.

In order to identify areas where desertification may have occurred over the last two decades, 109 stations located in three bioclimatic zones of Niger are analyzed. Time series of remote sensing data are well suited to this task. Here, we use time series of NOAA AVHRR normalized difference vegetation index (NDVI) data and rainfall data. In this study, trend analysis is used to identify areas within the biomes from 1981 to 1999 in Niger with apparent land degradation in semi-arid areas. It appears that most of Niger (98%) recorded increasing rainfall while only 76% experienced increasing maximum NDVI. However, the combination of the two variables through the ratio shows a widespread reduction of the rain-use efficiency with non significant trend for the stations located in northern Sahel (p=0.52), highly significant for those located in central Sahel (p=0.00009) and significant in southern Sahel (p=0.041). Overall, 75.3% of the sample recorded a significant reduction of the NDVIMax/RR ratio. Only one station out of four (24.7%) presented a stability of the ratio. These negative trends suggest a progressive diminution of the vegetation productivity as highlighted by the lowering of the NDVIMax/RR ratio. This situation suggest a consistently environmental degradation and that desertification processes continued during the last two decades over most of the Sahelian belt of Niger. [less ▲]

Variations in the amount of different RNA species were investigated during in vitro maturation of bovine oocytes. Total RNA content was estimated to be 2 ng before meiosis, and after meiosis resumption, no decrease was observed. Ribosomal RNA did not appear to be degraded either, whereas poly(A) RNA was reduced by half after meiosis resumption, from 53 pg to 25 pg per oocyte. Real-time polymerase chain reaction was performed on growth and differentiation factor-9 (GDF-9), on cyclin B1, and on two genes implicated in the resistance to oxidative stress, glucose-6-phosphate-dehydrogenase (G6PD) and peroxiredoxin-6 (PRDX6). When these transcripts were reverse-transcribed with hexamers, the amplification results were not different before or after in vitro maturation. But when reverse transcription was performed with oligo(dT), amplification was dramatically reduced after maturation, except for cyclin B1 mRNA, implying deadenylation without degradation of three transcripts. Although calf oocytes have a lower developmental competence, their poly(A) RNA contents were not different from that of cow oocytes, nor were they differently affected during maturation. When bovine oocytes were maintained in vitro under meiotic arrest with CDK inhibitors, their poly(A) RNA amount increased, but this rise did not change the poly(A) RNA level once maturation was achieved. The increase could not be observed under transcription inhibition and, when impeding transcription and adenylation, the poly(A) RNA decreased to a level normally observed after maturation, in spite of the maintenance of meiotic arrest. These results demonstrate the importance of adenylation and deadenylation processes during in vitro maturation of bovine oocytes. [less ▲]

Children’s morphosyntactic disorders have been studied extensively over the past few years, but mostly in English-speaking children. Recent data on French-speaking children are presented in the current article. There are three key-periods in morphological development : (1) language emergence ; (2) beginning of morphosyntax ; (3) later development. Different morphosyntactic features correspond to each of these periods in the language production of SLI children. The difference between language delay and language disorder is difficult to tease apart in young children. However, as children grow older, it becomes possible to identify characteristics that are specific to children with language disorders and others that are specific to French-speaking SLI children.

The present research examined the quality of the phonological representations of French children with specific language impairment (SLI) and those with normal language development (NLD). Twenty-five children with SLI and fifty normally developing children matched on lexical age level participated in an auditory lexical decision task. The observations gathered in our study can be summarized as follows. First, children with a higher receptive lexical level performed better, and this was true both for children with NLD and children with SLI. Second, both children with NLD and SLI were more likely to reject pseudo-words resulting from a modification affecting the number of syllables of a word than pseudo-words resulting from a slight modification with the number of syllables unchanged. This difference, however, was greater for the children with SLI who appeared to have much difficulty rejecting pseudo-words resulting from slight modifications. Finally, the performance of children with SLI was particularly poor when presented with pseudowords resulting from a slight modification at the beginning or the end of a word. These findings are interpreted as supporting the hypothesis of an underspecification of phonological representations in children with SLI. [less ▲]

We report about the physical properties of samples obtained by different substitutions on the Mn site of LaMnO3: LaMn0.85Ni0.15O3, LaMn0.85Ga0.15O3 and LaMn0.5Ga0.5O3. It is well known that the antiferromagnetic orbitally ordered ground state of LaMnO3 is easily destroyed to give way to ferromagnetism. However, this ferromagnetic behaviour can result from several mechanisms: depending on the nature of the substituting cation and on the substitution level, the physical properties derived from a complex interplay between exchange interactions, orbital ordering and Jahn-Teller distortion. As a result, there are noticeable differences between the physical properties of the different samples, even though all three samples display a ferromagnetic component in zero applied magnetic field. In this paper we compare the crystallographic, electrical and magnetic properties of these samples, with a special attention for the AC susceptibility behaviour. (C) 2004 Elsevier B.V.

The issue of jurisdiction certainly constitutes one of the main challenges of what is commonly called globalisation, i.e. the rapid internationalisation of economic (and, to a somewhat lesser extent, of other) activities. Since legal regulation of these human activities is still largely state-based with the notable exception of the European Union, whose existence and the large body of rules it produces, also raises questions of jurisdiction rules on jurisdiction are necessary to define which part of these activities can be subject to regulation by a given State. This paper aims to examine what private international law has achieved to answer the question of jurisdiction. [less ▲]

This study compared the interactions of coaches and athletes in three highly different contexts. Coaches and athletes' strategies were explored through observation and qualitative interviews, then processed regarding what was at stake in their interactions and the resources they respectively possessed. Qualitative data analysis showed that strategies respectively adopted by coaches and athletes in the three contexts were similar to the collective activity labelled "tacit cooperation" in organizational psychology. Financial, political and symbolic stakes were proposed as argument explaining these similarities. [less ▲]

During the past decades, the incidence of skin cancers has been on the rise in Wallonia as in other regions of similar latitude in the rest of the world. Awareness of the population to the dangers of sun exposure and to the benefit of early cancer diagnosis is of the upmost importance and undisputed. The impact of the information delivered by the media and of the actions initiated by physicians is heterogeneous. The positive and unquestionable aspect is hampered if the population at risk is not properly targeted. It is also reduced if the problem understanding creates a surge in telly-belly syndrome.

Diaper dermatitis is a frequent condition. Several clinical types are distinguished. The most frequent type results from increased fragility of the newborn buttock skin when covered by diapers. According to the mechanisms involved and the severity of the dermatitis, one can distinguish the intertrigo of the chubby baby, and the so-called "W", "Y" and "red panties" types of diaper dermatitis. When the effects of occlusion are not controlled by adequate absorption by the diapers, hyperhydration of the stratum corneum occurs and progresses to maceration. As a result, the value of the coefficient of friction of the skin increases with epidermal weakening to rubbing. In addition, fecal enzymes (urease, proteases and lipases) alter urines and skin. Judicious hygiene measures and the correct choice of diapers are mandatory. Cutaneous colonization by microorganisms, the most important of which being Candida albicans, is the main complication. Adequate preventive and curative measures can combat diaper dermatitis with confidence. A miconazole paste allows to improve the tribological properties of the interface between diapers and the skin. It also abates the impact of Candida albicans in the pathogenesis of the skin disorder. [less ▲]

Olfactory ensheathing cells (OECs) together with olfactory nerve fibroblasts (ONFs) and neonatal astrocytes are potent stimulators of neurite growth in adulthood and during development, respectively. Since it is known that alignment of glial cells is important for the correct outgrowth of axon tracts, it was hypothesized that the alignment of glial cells stimulates directional and enhanced neurite outgrowth. Adult OEC/ONF and neonatal astrocytes were cultured either on biodegradable poly(D,L)-lactide matrices or in Petri dishes for 4 days. Thereafter neonatal cerebral cortical neurons were added. After a 2-days coculture period the cultures were fixed and processed for a combined MAP-2 and phosphorylated neurofilament (RT97) staining. The neurite growth (neurite elongation and neurite formation) and the neurite direction were assessed. We show that (1) OEC/ONF cultures are more potent in stimulating the length of the longest neurite of cocultured neurons, (2) alignment of glial is achieved in vitro on our biomatrices, (3) aligned glial/biomatrix complexes do not enhance neurite growth, and (4) aligned glial/biomatrix complexes direct neurite outgrowth. These data have significant implications for in vivo experiments focusing on glial transplantation. Transplanting glial/biomatrix complexes may stimulate the directional regrowth of severed axons across a lesion site. (C) 2004 IBRO. Published by Elsevier Ltd. All rights reserved. [less ▲]

Introduction : Le dossier de santé informatisé (DSI), utilisé quotidiennement en soins primaires, peut constituer un instrument de récolte de données utilisables localement pour l’amélioration de la qualité des soins et, à une plus grande échelle, une base de données épidémiologiques. Malgré une politique de promotion du DSI de la Fédération des Maisons médicales belges francophones, son utilisation reste très marginale. Méthodes : Huit maisons médicales motivées par l’informatisation de leur dossier ont été rencontrées. Des indicateurs quantitatifs d’utilisation du DSI ont été mesurés. Une évaluation qualitative des résistances à l’informatisation et des solutions pouvant y être apportées a été réalisée par la technique du groupe nominal. Résultats : L’utilisation du DSI reste faible, sauf exception. Les solutions proposées ont pu être regroupées en 5 catégories : éthique (confidentialité, relation avec le patient, relation du thérapeute avec la machine), formation (à l’informatique, à la logique classificatoire, formation accessible), recherche de sens (envie d’utiliser les outputs locaux dans des projets d’amélioration de la qualité des soins, comparaison avec d’autres praticiens, encadrement local), pratique (amélioration du logiciel, amélioration de l’organisation interne des équipes, gestion du temps passé à l’encodage des données) et pluridisciplinarité (coordination entre secteurs, effort soutenu par l’ensemble de l’équipe, projets communs). Discussion : Les praticiens sont prêts à s’informatiser s’ils en retirent des bénéfices immédiats (connaissance de leur patientèle et de leur fonctionnement d’équipe). Ils ont exprimé le besoin de disposer d’un outil simple à utiliser, qui ne leur fasse pas perdre de temps et qui respecte leurs spécificités de travail et d’organisation (équipe pluridisciplinaires et autogérées). Ils ont exprimé le besoin d’un soutien extérieur, sous forme de formations adaptées et d’encadrement pour la gestion des données. Les préoccupations de type éthique (sécurité, transfert de données, place de l’ordinateur dans la relation avec le patient) sont étonnamment peu présentes. [less ▲]
