Diagnostic validity of ICD-10 acute and transient psychotic disorders and DSM-5 brief psychotic disorder
Full text linkBackground Short-lived psychotic disorders are currently classified under “acute and transient psychotic disorders” (ATPDs) in ICD-10, and “brief psychotic disorder” (BPD) in DSM-5. This study's aim is to review the literature and address the validity of ATPDs and BPD. Method Papers published between January 1993 and December 2016 were identified through searches in Web of Science. Reference lists in the located papers provided further sources. Results A total of 295 articles were found and 100 were included in the review. There were only a few studies about the epidemiology, vulnerability factors, neurobiological correlates and treatment of these disorders, particularly little interest seems to exist in BPD. The available evidence suggests that short-lived psychotic disorders are rare conditions and more often affect women in early to middle adulthood. They also are neither associated with premorbid dysfunctions nor characteristic family predisposition, while there seems to be greater evidence of environmental factors particularly in developing countries and migrant populations. Follow-up studies report a favourable clinical and functional outcome, but case identification has proved difficult owing to high rates of transition mainly either to schizophrenia and related disorders or, to a lesser extent, affective disorders over the short- and longer-terms. Conclusions Although the lack of neurobiological findings and little predictive power argue against the validity of the above diagnostic categories, it is important that they are kept apart from longer-lasting psychotic disorders both for clinical practice and research. Close overlap between ATPDs and BPD could enhance the understanding of these conditions
Error estimation and adaptive meshing in 3D electrostatic and magnetostatic problems
No full textA local error estimation and adaptive meshing method developed by some of the authors for finite element analysis of 2D electrostatic and magnetostatic problems is now extended to 3D problems. The problems are formulated in terms of scalar potentials and discretized on a tetrahedral mesh using linear shape functions. Local error is estimated by approximately solving an independent differential problem in each tetrahedral element. The elements selected for refinement are subdivided by adding nodes inside the element, or along an edge, depending on their geometrical quality facto
Adaptive FEM in 3D non-linear magnetostatics
No full textAn adaptive FEM for 3D magnetostatic problems involving non-linear materials and permanent magnets is presented. The problems are formulated in terms of scalar potentials and discretized on a tetrahedral mesh using linear shape functions. Local error is estimated by approximately solving an independent differential problem in each tetrahedral element

Early-adult outcome of child and adolescent mental disorders as evidenced by a national-based case register survey
Full text linkBackground Mental disorders show varying degrees of continuity from childhood to adulthood. This study addresses the relationship of child and adolescent mental disorders to early adult psychiatric morbidity. Methods From a population at risk of 830,819 children and adolescents aged 6-16 years, we selected all those (n = 6043) who were enrolled for the first time in the Danish Psychiatric Register with an ICD-10 F00-99 diagnosis in 1995-1997, and identified any mental disorder for which they received treatment up to 2009. Results Neurodevelopmental and conduct disorders were the principal diagnostic groups at 6-16 years and exhibited a characteristic male preponderance; while affective, eating, neurotic, stress-related and adjustment disorders were more common in girls. Over a mean follow-up period of 10.1 years, 1666 (27.6%) cases, mean age 23.4 years, were referred for treatment to mental health services, and they had a markedly higher risk than the general population (RR 5.1; 95% CI 4.9-5.4). Affective, eating, neurodevelopmental, obsessive-compulsive and psychotic disorders had the strongest continuity. Heterotypic transitions were observed for affective, eating, neurodevelopmental, personality and substance use disorders. Conclusions These findings suggest that individuals with psychiatric antecedents in childhood and adolescence had a high risk of being referred for treatment in early adulthood, and many mental disorders for which they required treatment revealed both homotypic and heterotypic continuity
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
