Introduction : Les médecins généralistes jouent un rôle majeur dans la détection et la gestion des abus de substances. L'étude présentée ici investiguait les facteurs qui influencent leur implication concernant la gestion des abus d'alcool, des drogues illégales, des hypnotiques et des anxiolytiques dans la population belge des 18-65 ans. Méthode : 20 MG ont été interrogés par entretiens semi-directifs. Le I-Change Model de de Vries a été utilisé pour construire le guide d'entretien et analyser les données récoltées. Il s'agit d'un modèle de prédiction du comportement. Résultats : Parmi les principaux résultats de l'étude, il ressortait que les MG étaient fortement influencés dans leur approche par leurs propres représentations de l'abus, qui oscillait leurs responsabilités professionnelles envers ces patients et la responsabilité de ces derniers quant à la gestion de leur santé, avec l'idée de faute morale en substrat. En ce sens, l'abus de substance était perçu sur un continuum entre l'abus comme forme de maladie chronique d'une part, et la faute morale d'autre part. L'alcool et le cannabis étaient néanmoins mieux acceptés socialement que les autres substances. Les propres expériences personnelles des généralistes concernant les abus avaient aussi une incidence sur leur volonté de s'investir avec ces patients. Pour autant, les pratiques multidisciplinaires (notamment au forfait) et l'expérience étaient évoquées comme des facteurs importants quant à l'engagement dans la gestion. Les contraintes temporelles et l'investissement demandé étaient, en revanche, considérés comme des barrières. Discussion : Les facteurs motivationnels apparaissaient centraux dans la décision de s'investir dans la gestion des abus de substances, bien davantage que les connaissances théoriques et les formations qui semblaient plus secondaires. La peur du burnout s'exprimait donc en substrat. La formation des MG devrait tenir compte de ce souhait de se protéger, afin de favoriser simultanément une approche centrée sur le patient. [less ▲]

Purpose: Aggregated results of systematic reviews separately show how light used as a treatment and some occupational therapy interventions could have a positive impact on psychobehavioural disorders in older people. Since the beginning of June 2014 the Walloon Government has been financing a project which consists of a non-pharmacological approach that combines light and occupational therapy for a psychogeriatric population with specific symptoms: spatial and temporal disorientations, apathy, depression, agitation, anxiety, confusion and circadian disorder. The objective of this abstract is to expose the assumptions that the combination of two different light devices and one specific occupational therapy program could have an impact on the different symptoms of a psychogeriatric population. Methods: To build our hypothesis, two literature reviews have been achieved. The first one concerning the use of light as therapy gathered 30 studies while the other one about occupational therapy activities collected 35 articles. Results: Despite of a heterogeneity between studies dealing with light and occupational therapy, the combination of these two non-pharmacological interventions might fight the depressive syndrome, reduce the temporal disorientation thanks to a regularity in the period of activity, restore the circadian rhythm and so reduce some troubles that can be linked to them: sleep disorder, risk of fall, apathy, agitation, behavioural and cognitive troubles (attention, concentration). Moreover, one of the two light devices used which can modulate the light intensity according to the rooms might reduce the spatial disorientation if it’s employed as a landmark. Conclusions: Based on literature reviews and our experience into this field it’s seems that a non-pharmacological approach involving light and occupational therapy intervention could have a positive effect on symptoms of psychogeriatric population. In admitting that those effects are becoming true after experimentation and analyses, we can also expect an improvement of the quality of life. [less ▲]

In this article, we study the Public-Private Partnerships (PPP) in the field of employment, in Belgium. These PPPs are established between Public Employment Service (PES) and private operators to create projects for support and training for jobseekers the ultimate goal of which is social and professional reintegration. There are three critical moments in the life of the partnership: getting a partnership agreement with the PES, mobilizing jobseekers to participate in the delivery, and evaluating the outcomes achieved by the operator. The parties affected by these three critical steps are mainly the private operators. To overcome these difficulties, the providers implement informal and "clandestine" strategies to ensure the proper operation of the partnership and especially its performance and sustainability.

Introduction: Identifying patients who need damage control resuscitation (DCR) early after trauma is pivotal for adequate management of their critical condition. Several trauma-scoring systems have been developed to identify such patients, but most of them are not simple enough to be used in prehospital settings in the early post-traumatic phase. The Trauma Induced Coagulopathy Clinical Score (TICCS) is an easy-to-measure and strictly clinical trauma score developed to meet this medical need. Methods: TICCS is a 3-item clinical score (range: 0 to 18) based on the assessment of general severity, blood pressure and extent of body injury and calculated by paramedics on-site for patients with severe trauma. This non-interventional prospective study was designed to assess the ability of TICCS to discern patients who need DCR. These patients were patients with early acute coagulopathy of trauma (EACT), haemorrhagic shock, massive transfusion and surgical or endovascular haemostasis during hospitalization. Diagnosis of EACT was assessed by both thromboelastometry and conventional coagulation tests. Results: During an 18-month period, 89 severe trauma patients admitted to the general emergency unit at our hospital were enrolled in the study, but 7 were excluded for protocol violations. Of the 82 remaining patients, 8 needed DCR and 74 did not. With receiver operating characteristic curve analysis, TICCS proved to be a powerful discriminant test (area under the curve = 0.98; 95% CI: 0.92 to 1.0). A cutoff of 10 on the TICCS scale provided the best balance between sensitivity (100%; 95% CI: 53.9 to 100) and specificity (95.9%; 95% CI: 88.2 to 99.2). The positive predictive value was 72.7%, and the negative predictive value was 100.0%. Conclusion: TICCS can be easily and rapidly measured by paramedics at the trauma site. In this study of blunt trauma patients, TICCS was able to discriminate between patients with and without need for DCR. TICCS on-site evaluation should allow initiation of optimal care immediately upon hospital admission of patients with severe trauma in need of DCR. However, a larger multicentre prospective study is needed for in-depth validation of TICCS. [less ▲]

Epitaxy of metal oxides is of great interest since it provides a way to obtain desired novel properties for the applications such as electronics and energy. However, earlier epitaxy research's have been restricted because of the limited range of compositions and low-index of commercially available single crystal substrates. Consequently, novel epitaxy synthesis methods need to be developed in order to go beyond the present demands of of single crystal substrates in terms of phase, composition, size, orientation and symmetry. In this research work, we have developed a high-throughput synthesis process, called combinatorial substrate epitaxy (CSE), where an oxide film is grown epitaxially on a polycrystalline substrate. As a proof-of-concept, we firstly fabricated Ca3Co4O9 films on Al2O3 ceramics. Films have a good local epitaxial registry, and the Seebeck coefficient is about 170 µV/K at 300 K. High quality BiFeO3/La0.7Sr0.3MnO3 thin film heterostructures were secondly deposited on dense LaAlO3 ceramics prepared by spark plasma sintering. Piezoforce microscopy was used to confirm the local ferroelectric properties. Thirdly, we investigate the growth of of metastable monoclinic Dy2Ti2O7 epitaxial films on polycrystalline La2Ti2O7 substrates. We conclude that CSE approach opens the way towards unexpected electronic properties in oxide films. [less ▲]

Locust bean gum (LBG) galactomannans are polysaccharides consisting of a β-(1→4) D-mannopyranosyl backbone substituted to varying degrees in α-(1→6) with single D-galactopyranosyl residues. This basic structure is the same for all galactomannans (Fig. 2). However, when locust bean gum is extracted at different temperatures, the generated fractions exhibit different properties in aqueous solution (viscosity, viscoelasticity, gel formation, thermohydrolysis resistance, etc.). This means that there are differences within the fine structure of the polymers (although the basic structure is the same). Analysis of [13C]-NMR spectra of galactomannans, in combination with other techniques, can provide capital information about fine structural elucidation of the polymers. The method specifies the distribution of lateral galactosyls along the main chain of mannans. Two fractions extracted from locust bean gum at 25 and 80 °C (respectively GM25 and GM80) were comparatively studied by [13C]-NMR. Mannosyls/Galactosyls (M/G) ratios can be determined by considering the intensities of C-1 mannose and galactose signals in [13C]-NMR spectra. This method provides results relatively close to those obtained by GC-MS analysis. Spectra also showed that resonance from C4 of D-mannose residues were split, in evident dependence upon the nearest-neighbor probabilities (“diad frequencies”) of D-galactosyl groups along the mannan chains (Fig. 2). Diad frequencies were obtained by integrating C4(Man) peak areas. F11, F21/F12 and F22 gave respectively the di-, mono- or non-substituted mannose pairs proportions. High percentages of F11 and F22 therefore indicate a more non-homogeneous distribution of lateral galactosyls along the polysaccharide backbone as observed for GM80. The percentages of total lateral substituents obtained by C4(Man) peak analysis [F11 + (F21 or F12)/2] were fairly well correlated with M/G ratios. Splitting of the C-6 substituted D-mannose resonance provides, therefore the basis for determining the next-nearest-neighbor probabilities (triad frequencies) (Fig. 2). However, the spectrum is often not sufficiently resolved to accurately quantify and interpret the results. [less ▲]
