Potential use of lurasidone for the treatment of bipolar psychosis
No full textIntroduction: Second-generation antipsychotics (SGA) are new treatment options for bipolar disorders (BDs). Lurasidone is one such SGA, which is currently approved as a monotherapy for bipolar I depression (BPID) and as an add-on therapy for acute schizophrenia.Areas covered: In this drug evaluation, the authors illustrate the pharmacological profile of lurasidone and review its development history. The aim of this review is to evaluate whether this compound could be used in psychotic BDs.Expert opinion: The pharmacological profile of lurasidone, its action on receptors, its role in neurogenesis and its cognitive performance suggests a potential use in psychotic episodes of BDs and mania. This hypothesis is also supported by the clinical observations from case reports concerning resolutions of BPID with psychotic features, where psychotic episodes were diagnosed as schizophrenia and reclassified as BDs after the patient was able to reconstruct his/her clinical history. The use of lurasidone may have the advantage of a low side-effect profile and a possible efficacy in preventing the impairment of cognitive performance. However, randomized clinical trials assessing the efficacy of lurasidone in the treatment of manic episodes as well as manic episodes with psychotic components are still needed

Decreases in depression over 20 years in a mining area of Sardinia: Due to selective migration?
No full textBackground
The objective of the study was to determine if community surveys, conducted 3 times over a period of 20 years in a small district of Sardinia (Italy), confirm the increase in depressive disorders reported in the recent literature.
Methods
Three community surveys were carried out on randomized samples of the same Sardinian mining area in 1988, 1998 and 2008. The surveys were conducted using the interview “Present State Examination” in 1988 (Depression diagnosed with ICD-IX) and the CIDI-S in 1998 and 2008 (Major Depression diagnosed with ICD-X). The three surveys produced estimates of one-month prevalence and of lifetime prevalence in 1998 and 2008.
Results
Our work found a substantial decrease in depressive disorders from the survey conducted in 1998 to the survey in 2008 using a similar methodology, except in the youngest age group, which showed an increase in the rate. A decrease in the frequency of depressive disorders compared to what was found 20 years ago was also observed. However, in this case the comparison is more problematic because of use of different diagnostic systems.
Discussion
The research seems to show a decrease in depressive disorders over the past two decades. While the small population examined makes it difficult to generalize the overall findings, this study suggests that the hypothesis of an increase in the incidence of depressive disorders since the 1980s in western countries, should have exceptions. A complex interaction between socio-economic (mining closure and large migration) and biological factors (possible selective migration) is likely to influence changes in the prevalence of mood disorders. However, due to certain limitations of this study, this hypothesis may be considered from an heuristic perspective
MDQ positive people's searching for effective and ineffective treatments for bipolar disorders: a screening study in France
No full textINTRODUCTION:
The objective was to estimate the rate of subjects who tested positive at a screening for bipolar disorders among the people insured by a French Health Company, and subsequently to measure treatment patterns.
METHODS:
Cross-sectional postal survey on the "Mutuelle Générale de l'Education Nationale" (MGEN) policyholders. A self-rated questionnaire was sent by mail to 20,099 individuals randomly selected among MGEN policyholders. Tools: questionnaire on socio-demographic variables and health-care use; Mood Disorder Questionnaire (MDQ); Composite International Diagnostic Interview Short Form Self-Administered (CIDI-SA).
RESULTS:
Responders were 10,288 (53%). The prevalence of MDQ positivity (MDQ(+)) was 3.6%. The respondents older than 65 showed the lowest frequencies. High frequencies were recorded by the people who had left work because of long term sickness and by people with invalidity. Subjects having a diagnosis of ICD-10 major depression were found to be at risk. Positive subjects had no more contacts with general practitioners than negative subjects; on the contrary they had more contacts with psychiatrists, alternative medicine professionals, psychologists, psychoanalysts, spiritual guides or welfare workers. MDQ+ subjects had a higher risk to use all kinds of psychodrugs, including antidepressants (27.7%, OR=2.7, CI95% 1.9-3.9).
DISCUSSION:
The prevalence of MDQ(+) was similar to the surveys in the USA and Italy. The use of ADs in people with MDQ(+) and MDD diagnosis needs to be taken into account when managing the public health-care system. A large rate of positive subjects reported to have used ineffective treatments for bipolar disorders.
LIMITS:
Relative low response rate and observational design
Coping with the crisis: people with severe mental disorders acting for social change through sustainable energy.
Full text linkBackground: The aim of the study was to examine the efficacy of a vocational training program on renewable energy sources in reducing disabilities of people with chronic psychosis (CP). The innovative element was that the project could produce major advantages regarding the economic needs of the whole area involved. Methods: Experimental Cohort, 26 subjects with CP (EC); Control Cohort1, 130 subjects with CP following pharmacotherapy plus other rehabilitation activities (CIC); Control Cohort2, 101 subjects with CP following the usual treatment (pharmacotherapy) (CUC). Study tool: Health of the Nation Outcome Scales (HoNOS). Assessment made at the start of the study (T0) and after three months (T1). Statistical analysis made by MANOVA. Results: Improvement in HoNOS total score in both groups (F=7.574, p=0.000) with non-significant differences between groups over time (F=1.336, p=0.252) was found comparing EC vs. CIC. Greater improvement in EC vs. CIC was shown in the HoNOS "impairment" scale (F=4.910, p=0.028). EC vs. CUC: both groups improved in HoNOS total score (F=9.440, p=0.000) but the improvement was greater in EC (F = 2.273, P=0.048). Conclusions: Work inclusion, as well as other rehabilitation treatments, reduces the social needs of people with chronic psychosis. Work inclusion in a project with real relevance for the area where these people live, produces more improvement of cognitive, physical and somatic disabilities, probably related to a better outcome in self-efficacy
Validation of the Italian Version of the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN): Some Considerations on its Screening Usefulness
No full textGoing 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
