Using functional magnetic resonance imaging (fMRI), we recently demonstrated that nonmedicated patients with a first episode of unipolar major depression (MDD) compared to matched controls exhibited an abnormal neural filtering of irrelevant visual information (Desseilles et al., 2009). During scanning, subjects performed a visual attention task imposing two different levels of attentional load at fixation (low or high), while task-irrelevant colored stimuli were presented in the periphery. In the present study, we focused on the visuo-attentional system and used "Dynamic Causal Modeling" (DCM) on the same dataset to assess how attention influences a network of three dynamically-interconnected brain regions (visual areas V1 and V4, and intraparietal sulcus (P), differentially in MDD patients and healthy controls. Bayesian model selection (BMS) and model space partitioning (MSP) were used to determine the best model in each population. The best model for the controls revealed that the increase of parietal activity by high attention load was selectively associated with a negative modulation of P on V4, consistent with high attention reducing the processing of irrelevant colored peripheral stimuli. The best model accounting for the data from the MDD patients showed that both low and high attention levels exerted modulatory effects on P. The present results document abnormal effective connectivity across visuo-attentional networks in MDD, which likely contributes to deficient attentional filtering of information. [less ▲]

BACKGROUND: In Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon. METHODS/DESIGN: The objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade. DISCUSSION: As school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.

Before implementing the TADAM project in Belgium (a heroin-assisted treatment trial), our research team studied the trials in other countries. Since 1994, six randomised controlled trials have been developed using the same treatment model of heroin-assisted treatment (HAT). Each trial concluded that HAT had more efficacy than methadone treatment. We analysed those trials in order to find on which levels patients in a HAT treatment are expected to improve. Improvements appeared after at least six months on the level of street heroin use, (physical and mental) health and criminal behaviour. In the longer term, the continuation of treatment had positive but limited effects on the social level. Due to his higher cost, this treatment should remain a second-line treatment for this special target group: severe heroin addicts, using continuously street heroin in spite of a methadone treatment.

Background: TADAM, a randomised controlled trial of heroin-assisted treatment, will begin in Liège, Belgium, in 2010. This trial will compare two groups of patients: one in a heroin-assisted treatment and the other in oral methadone treatment. In this new medical treatment, the criminal behaviour of the patients will also be assessed. It is one of the three efficacy criteria. Why? Methodology: We based our presentation on papers published on heroin-assisted treatment concerning changes in criminal behaviour. Results: Heroin-assisted treatment of treatment resistant heroin addicts has been successfully tested in six countries: Switzerland, The Netherlands, Spain, Germany, Canada and United-Kingdom. Each country has also assessed the criminal behaviour before and after the treatment with better results for heroin-assisted treatment than for methadone treatment. Conclusion: HAT seems a good way to treat criminal behaviour of a group: severely heroin addicts who already tried other treatments. [less ▲]
