    ObjectivesA supportive social network is associated with better mental health and wellbeing, and less criminal behavior. Therefore, this study examined the effectiveness of an additive informal social network intervention to treatment as usual (TAU) among forensic psychiatric outpatients.Materials and methodsAn randomized controlled trial (RCT) was conducted in forensic psychiatric care, allocating eligible outpatients (N = 102) to TAU with an additive informal social network intervention or TAU alone. Participants receiving the additive intervention were matched to a trained community volunteer over 12 months. TAU consisted of forensic care (e.g., cognitive behavioral therapy and/or forensic flexible assertive community treatment). Follow-up assessments were conducted at 3, 6, 9, 12, and 18 months after baseline. The primary outcome was the between-group effect on mental wellbeing at 12 months. Between-group effects on secondary outcomes (e.g., general psychiatric functioning, hospitalization, criminal behavior) were explored.ResultsIntention-to-treat analyses showed non-significant between-group effects on mental wellbeing on average over time and at 12 months. However, significant between-group effects were found on hospitalization duration and criminal behavior. Specifically, TAU participants were hospitalized 2.1 times more days within 12 months and 4.1 more days within 18 months than participants in the additive intervention. Furthermore, TAU participants reported 2.9 times more criminal behaviors on average over time. There were no significant effects on other outcomes. Exploratory analyses revealed that sex, comorbidity, and substance use disorders moderated effects.ConclusionThis is the first RCT examining the effectiveness of an additive informal social network intervention in forensic psychiatric outpatients. Although no improvements were found on mental wellbeing, the additive intervention was effective in reducing hospitalization and criminal behavior. The findings suggest that forensic outpatient treatment can be optimized by collaborating with informal care initiatives aimed at improving social networks within the community. Future research is warranted to determine which specific patients might benefit from the intervention and if effects can be improved by extending the intervention duration and enhancing patient compliance.Clinical Trial Registration: [https://trialsearch.who.int/Trial2.aspx?TrialID=NTR7163], identifier [NTR7163]

    A cognitive remediation training for young adults with psychotic disorders to support their participation in education - study protocol for a pilot randomized controlled trial

    Background: Most severe mental disorders have their onset between the age of 17 and 27, a time when many young adults begin participating in secondary or post-secondary education. The cognitive deficits typically associated with psychiatric disorders, especially psychotic disorders, increase the risk of leaving school early, which can lead to a reduction in employment opportunities later on in life and, in turn, a poorer long-term prognosis. Therefore, specific interventions aiming to improve these cognitive functions are needed. Cognitive remediation (CR) aims to improve cognitive functioning and may increase real-world functioning in educational performance. This study aims to examine the feasibility and applicability of a CR training named Mindset for students with psychotic disorders in the Netherlands. Methods/design: Sixty students diagnosed with a psychotic disorder and currently reporting cognitive deficits will be included from four Dutch Mental Health Care institutes. Half of the participants (N = 30) will be randomly assigned to the CR training consisting of twelve, individual, weekly 1-h meetings. The other half will be assigned to an active control condition consisting of twelve weekly assignments that will be sent by email aiming to improve school performance. Students will be evaluated at baseline (T0), directly after finishing the CR training or control intervention (T1), and 6 months later (T2). Treatment feasibility will be the primary outcome, using evaluation forms, interviews with trainers and participants, number of study drop outs, and patient eligibility and recruitment rates. School functioning, cognitive functioning, and strategy use will also be assessed to get a preliminary idea of the potential effectiveness of the intervention. Discussion: The CR training in this study will provide real-world examples and exercises aimed to teach useful strategies to cope with the cognitive deficits experienced by students with psychotic disorders. Furthermore, since students with other psychiatric disorders might also experience cognitive deficits, the results of this study may also provide some further implications for future studies on the effect of this CR training for students with these disorders. Trial registration: The study was registered with Trialregister.nl, no. NL6590 (NTR6764), date registered: September 7, 2017. Register name: Mindset.

    Consistent patterns of common species across tropical tree communities

    Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we investigate abundance patterns of common tree species using inventory data on 1,003,805 trees with trunk diameters of at least 10 cm across 1,568 locations1,2,3,4,5,6 in closed-canopy, structurally intact old-growth tropical forests in Africa, Amazonia and Southeast Asia. We estimate that 2.2%, 2.2% and 2.3% of species comprise 50% of the tropical trees in these regions, respectively. Extrapolating across all closed-canopy tropical forests, we estimate that just 1,053 species comprise half of Earth’s 800 billion tropical trees with trunk diameters of at least 10 cm. Despite differing biogeographic, climatic and anthropogenic histories7, we find notably consistent patterns of common species and species abundance distributions across the continents. This suggests that fundamental mechanisms of tree community assembly may apply to all tropical forests. Resampling analyses show that the most common species are likely to belong to a manageable list of known species, enabling targeted efforts to understand their ecology. Although they do not detract from the importance of rare species, our results open new opportunities to understand the world’s most diverse forests, including modelling their response to environmental change, by focusing on the common species that constitute the majority of their trees.Publisher PDFPeer reviewe

    Library Users: A Virtual Debate Among Artists on How and Why Libraries Matter to Them

    No full text
    C’est avec plaisir que je me suis chargée de recueillir ces points de vue. De nombreux artistes auraient pu être interrogés, et mes choix ne seront peut-être pas immédiatement évidents. J’aurais par exemple pu solliciter Dominique Gonzalez-Foerster et Douglas Gordon, pour ne citer que deux artistes qui ont beaucoup travaillé sur les livres. Les quatre participants au débat se sont plutôt intéressés à la forme de la bibliothèque et à sa dimension qualitative en tant qu’espace public. Leur intérêt porte davantage sur l’architecture, la conceptualisation et l’organisation de l’espace et la manière dont l’accès au savoir est facilité. Ils ne se sont rencontrés que de manière virtuelle, ce qui semble particulièrement à propos, puisqu’il s’agit d’un débat sur les bibliothèques, où œuvres et lecteurs se croisent et se mélangent à l’insu des auteurs. Certains croisements inopinés se sont produits. Luísa Cunha, par exemple, se penche sur la Bibliothèque générale de Coimbra, qui date du milieu du xxe siècle, et qui figure dans les photographies de Candida Höfer, à côté de la très célèbre Biblioteca Joanina, qui remonte au xvie siècle. Le contraste entre les deux édifices (situés de part et d’autres de la même rue), démontre que ces artistes apprécient tout autant les bibliothèques « banales » que les bibliothèques d’exception, du moment qu’elles remplissent leur fonction. Chaque participant a répondu à mes questions (et non aux questions des autres artistes). Les résultats ont donc été influencés par la recherche que j’ai menée en tant qu’utilisatrice de bibliothèque

    Preservation of the Pectoral Fascia in Mastectomy With Immediate Reconstruction: A Nationwide Survey

    Get PDF
    Introduction: Pectoral fascia (PF) removal during mastectomy still seems to be the standard procedure. However, preservation of the PF might improve postoperative and cosmetic outcomes, without compromising oncological safety. Here, we report on a national survey among Dutch plastic surgeons and oncological breast surgeons to evaluate their techniques and opinions regarding the PF. Materials and methods: A survey based study was performed in the Netherlands, in which both plastic surgeons and oncological breast surgeons were included, each receiving a different version of the survey. The surveys were distributed to 460 and 150 e-mail addresses, respectively. Results: A total of 68 responses were included from more than half of all Dutch medical centers. The results of this study indicate that circa one in five plastic surgeons and breast surgeons routinely preserve the PF during mastectomies and even more surgeons preserve the PF in specific cases. The surgical techniques and opinions regarding PF preservation widely differ between surgeons. Conclusions: Preservation of the PF does occur in a substantial part of the Dutch medical centers and techniques and opinions are contradictory. Future studies on this topic should clarify the effect of PF preservation on oncological safety, complication rates, postoperative pain, cosmetic outcomes, and patient satisfaction
