BACKGROUND: the objective of this study was twofold:1) Describe the use of antipsychotic treatments in ambulatory patients suffering from schizophrenia in Belgium.2) Evaluate to which extend antipsychotic treatment prescribing patterns are in accordance with published treatment guidelines. METHOD: A cross-sectional survey was carried out in 16 Belgian hospitals selected from a sample of 67 hospitals. The hospitals were equally distributed between the north and south part of the country and were representative of Belgian practice. During 2 months, participating psychiatrists were asked to record the medication use as well as demographic parameters of all consecutive ambulatory patients seen at their consultation or attending a day-hospital. Data concerning 1000 ambulatory patients with schizophrenia or schizoaffective disorder were collected. RESULTS: In Belgium, the use of atypical antipsychotics is frequent (69%) in ambulatory patients with schizophrenia. In the overall sample, 73% receive only one antipsychotic drug. The majority of patients are treated with drugs of only one antipsychotic drug group, either first- typical (29.8%) or second-generation, atypical antipsychotics (53.2%). 15.8% of patients combine different types of antipsychotics. Antipsychotic dosing is adequate for the majority of patients but about one fifth receives a higher than recommended dose as per package inserts. Polypharmacy remains within reasonable limits. The use of concomitant medication varies according the antipsychotic treatment: patients who take second-generation antipsychotics only, receive the least additional drugs. CONCLUSION: Atypical antipsychotics appear to be the first line treatment for schizophrenic psychosis. Psychiatrists working with ambulatory patients are well aware of treatment guidelines and follow them quite adequately. [less ▲]

A generic method for supervised classification of structured objects is presented. The approach induces a classifier by (i) deriving a surrogate dataset from a pre-classified dataset of structured objects, by segmenting them into pieces, (ii) learning a model relating pieces to object-classes, (iii) classifying structured objects by combining predictions made for their pieces. The segmentation allows to exploit local information and can be adapted to inject invariances into the resulting classifier. The framework is illustrated on practical sequence, time-series and image classification problems. [less ▲]

We are currently involved in a Franco-Thai program devolved to a multidisciplinary investigation of Muridae rodents (‘‘mice and rats''), their parasites and the pathogens that they may carry and/or transmit to human, with a better understanding of diseases emergence as an ultimate goal. In such a context, pathogens circulation in the wild is a complex but pivotal phenomenon which requires a continuum of scientific approaches to be accurately apprehended. In particular, a rigorously comparative study is mandatory in order to take into account the interactions between parasites, wild and domestic hosts (uncluding human) and their environment. This is the reason why we rely on both concepts and techniques from a wide range of disciplines including taxonomy, cytogenetics, phylogenetics, phylogeography, population genetics, ecology, geography as well as modeling. With the following objectives. Objective 1: To precisely identify and characterize the rodent species acting as reservoirs, and to document their ecology, geographic distribution as well as the genetic structure of their populations. To assess parasite and pathogen diversity in relation to their associated rodent hosts. To provide cophylogenies and co-phylogeographies in order to enlight the evolutionary relationships of hosts and parasites. Objective 2: To map and correlate the observed rodents distributions with their species-specific environmental landscapes in order to extrapolate their potential ‘‘real'' range and to anticipate their future distributions in relation to landscape modifications. Objective 3: Computing epidemiological databases. Crosschecking field data and GIS data. Definition and standardization of a risk-scale. Finalization of maps of risks and distributions. Atlas of Thai Muridae. Reference collection of Thai Muridae. Education and training of students. Following the listing of the objectives, we expose the first results of our studies and we sketch future projects. [less ▲]

Senecio inaequidens DC. was introduced from South Africa to Europe more than one hundred years ago, in a few precise locations linked to wool industry and extended its distribution throughout Europe. In a context of global warming, the potential evolution in germination and growth during the invasion process was studied in relation to altitude and climate. Seeds were collected along two transects (both altitudinal and climatic) in Belgium and France, going from the sea level to high altitudes (respectively 485 m and 1700 m) through the introduction spots. Respectively four and five climatic zones per transect, two populations per zone and ten randomly selected individuals per population were sampled. Seeds were sorted in order to discard maternal effects. Ten seeds per parent individual were thereafter sown in pots in a common garden experiment in Gembloux (Belgium). Germination was checked every two days. Height and diameter of plants, enabling the calculation of plant volume, were measured every 25 days. Despite an important variability, linear regression of first germination time (since sowing) vs altitude was significant (p = 0.001) for the French gradient, but not for the Belgian one. No significant difference was found in germination rate between climatic zones. For each of the three measurement times of plant height and diameter, regression of plant volume vs altitude was also significant for the French transect (p varying from 0.025 to 0.000 according to time), but not for the Belgian one. French plants from elevated locations germinated later and grow slowlier. These preliminary results suggest that contrasted climatic conditions in the French gradient, going from the Mediterranean coast to the Pyrrenean high elevations led to genetic differenciation of Senecio populations during its invasion in southern France. Less contrasted climatic conditions, together with a supposed loss of genetic variability (Lafuma 2003), did not lead to a clear differenciation in Belgium. References : Lafuma, L. (2003).

Invasion by alien plants can alter ecosystem processes and soil properties. In this study, we compared aboveground productivity, nutrient pools in standing biomass and topsoil (0-0.10 m) mineral nutrient concentrations between plots invaded by Early Goldenrod (Solidago gigantea) and adjacent, uninvaded, vegetation at five sites in Belgium. The five sites were characterised by a resident perennial herbaceous vegetation and spanned a wide range in soil fertility level and floristic composition. Invaded stands consistently had higher (2-3-fold) aboveground productivity and lower mineral element concentrations in standing phytomass. Nutrient pools (calculated as concentration x phytomass) was ca. twice higher in invaded plots, suggesting that S. gigantea might enhance nutrient cycling rates. Impacts on topsoil chemistry were surprisingly modest, with slightly higher nutrient concentrations under the invader. A noticeable exception was phosphorus, which showed higher concentrations of ammonium acetate-extractable fraction in invaded plots in four of five sites. It appears that S. gigantea does not significantly contribute to nutrient uplift from deep soil layers to topsoil, possibly because it does not root much deeper compared to resident vegetation.

The area in the midstream of the Mailuu-Suu River is the most landslide-prone and vulnerable of the entire Kyrgyzstan territory. More than 200 landslide sources distinct by genesis, age and development stages have been fixed at present in the outskirts of the Mailuu-Suu town within an area of 80 km2 only. The main reasons of mountain slopes instability in this area are the geologic conditions and geodynamic peculiarities of the region.

A primitive equation model and a statistical predictor are coupled by data assimilation in order to combine the strength of both approaches. In this work, the system of two-way nested models centred in the Ligurian Sea and the satellite-based ocean forecasting (SOFT) system predicting the sea surface temperature (SST) are used. The data assimilation scheme is a simplified reduced order Kalman filter based on a constant error space. The assimilation of predicted SST improves the forecast of the hydrodynamic model compared to the forecast obtained by assimilating past SST observations used by the statistical predictor. This study shows that the SST of the SOFT predictor can be used to correct atmospheric heat fluxes. Traditionally this is done by relaxing the model SST towards the climatological SST. Therefore, the assimilation of SOFT SST and climatological SST are also compared. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]
