ABSTRACT
Introduction: In 2020, the Directorate General of Health (DGS), a central service of the Ministry of Health in Portugal, approved and co-financed the first Open Dialogue program in the country. The present report aims to demonstrate the preliminary results of the first year of the project, implemented in the northern interior region of Alentejo. Methods: Seven people at the Center of Concern (PCC) and 21 family members/social networks received care through Open Dialogue; four external social workers and psychologists were also involved in the project as members of the support network. A total of 160 network meetings were undertaken, reaching as many as 27 per month in the busiest periods. Based on a previous Italian Research Protocol, developed by Pocobello et al. (non-published manuscript), quantitative and qualitative data were collected in and after the clinical meetings involving PCC and their family/social network, through a multi-method approach: clinical history interview (e.g., generic research on sociodemographic data, duration of untreated symptoms, reasons for requesting help, possible hospitalizations, and/or treatments/therapies) and the following scales applied every five sessions (e.g., CORE-OM, BSI, GAF, and LSNS-6). Results: The preliminary results indicate an improvement in global functioning and the enlargement of social network size/support, a decrease in symptoms, and a negative correlation between the number of sessions and the LSNS6. Medication use remained largely unchanged at the end of the project. Discussion: In general, even with a small sample, the results are considered satisfactory and seem to be aligned with the vast majority of Open Dialogue studies, which for several decades have consistently pointed toward better recovery rates than treatment as usual as well as increased client satisfaction. We expect that the results presented can boost further research and help strengthen the OD approach.
ABSTRACT
The aim of the present work was the simultaneous treatment of urban wastewater using microalgae and the energetic valorization of the obtained biomass. Chlorella vulgaris (Cv), Scenedesmus obliquus (Sc) and a naturally occurring algal Consortium C (ConsC) were grown in an urban wastewater. The nutrient removals were quite high and the treated water fits the legislation (PT Dec-Lei 236/98) in what concerns the parameters analysed (N, P, COD). After nutrient depletion the microalgae remained two more weeks in the photobioreactor (PBR) under nutritional stress conditions, to induce sugar accumulation (22-43%). The stressed biomass was converted into biohydrogen (bioH2), a clean energy carrier, through dark fermentation by a strain of the bacteria Enterobacter aerogenes. The fermentation kinetics were monitored and fitted to a modified Gompertz model. The highest bioH2 production yield was obtained for S. obliquus (56.8 mL H2/gVS) which was very similar when using the same algae grown in synthetic media.
