Rational Suicide in Late Life: A Systematic Review of the Literature
Full text linkBackground and Objectives: The complex concept of rational suicide, defined as a well-thought-out decision to die by an individual who is mentally competent, is even more controversial in the case of older adults. Materials and Methods: With the aim of better understanding the concept of rational suicide in older adults, we performed a systematic review of the literature, searching PubMed and Scopus databases and eventually including 23 published studies. Results: The main related topics emerging from the papers were: depression, self-determination, mental competence; physicians' and population's perspectives; approach to rational suicide; ageism; slippery slope. Conclusions: Despite contrasting positions and inconsistencies of the studies, the need to carefully investigate and address the expression of suicidal thoughts in older adults, as well as behaviours suggesting "silent" suicidal attitudes, clearly emerges, even in those situations where there is no diagnosable mental disorder. While premature conclusions about the "rationality" of patients' decision to die should be avoided, the possibility of rational suicide cannot be precluded
Family ad relatives of COVID-19 inpatients: The neglected needs of a vulnerable population
No full textThe Coronavirus disease 2019 (COVID-19) pandemic has violently impacted the Italian population and health care system, with relevant consequences on physical as well as on mental health. To date, the population of COVID-infected inpatients informal caregivers is still understudied, despite preliminary reports suggesting that anxiety may be a concern in this group of individuals. Higher awareness about the specific problems and needs of the relatives/careers/loved ones of COVID-19 inpatients is necessary, to implement prompt support and intervention strategies. The daily phone call may become a valuable opportunity to offer both clinical information about the patient and empathic listening and support to patients relatives, who may find it difficult to ask for help in another context
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Cognitive markers of psychotic unipolar depression: A meta-analytic study
No full textBackground The goal of the current meta-analysis was to review and examine in detail the features of cognitive performance in psychotic (MDDP) versus non-psychotic (MDD) major depressive disorder. Methods An electronic literature search was performed to find studies comparing cognitive performance in MDDP versus MDD. A meta-analysis of broad cognitive domains (processing speed, reasoning/problem solving, verbal learning, visual learning, attention/working memory) and individual cognitive tasks was conducted on all included studies (n=12). Demographic and clinical features were investigated via meta-regression analysis as moderators of cognitive performance. Results No difference in socio-demographic and clinical variables was detected between groups. In general, a poorer cognitive performance was detected in MDDP versus MDD subjects (ES=0.38), with a greater effect size in drug-free patients (ES=0.69). MDDP patients were more impaired in verbal learning (ES=0.67), visual learning (ES=0.62) and processing speed (ES=0.71) tasks. A significantly poorer performance was also detected in MDDP patients for individual tasks as Trail Making Test A, WAIS-R digit span backward and WAIS-R digit symbol. Age resulted to have a negative effect on tasks involved in working memory performance. Conclusion In line with previous meta-analyses, our findings seem to support an association between psychosis and cognitive deficits in the context of affective disorders. Psychosis during the course of MDD is associated with poorer cognitive performance in some specific cognitive domains, such as visual and verbal learning and executive functions
NCAM1, TACR1 and NOS Genes and Temperament: A Study on Suicide Attempters and Controls
Full text linkSuicide, one of the leading causes of death among young adults, seems to be plausibly modulated by both genetic and personality factors. The aim of this study was to dissect the potential association between genetics and temperament in a sample of 111 suicide attempters and 289 healthy controls. We focused on 4 genes previously investigated in association with suicide on the same sample: the nitric oxide synthase 1 and 3 (NOS1 and NOS3), the neuronal cell adhesion molecule 1 (NCAM1), and the tachykinin receptor 1 (TACR1) genes. In particular, we investigated whether a set of genetic variants in these genes (NOS1 : rs2682826, rs1353939, rs693534; NOS3 : rs2070744, rs1799983, rs891512; NCAM1 : rs2301228, rs1884, rs1245113, rs1369816, rs2196456, rs584427; TACR1 : rs3771810, rs3771825, rs726506, rs1477157) were associated with temperamental traits at the Temperament and Character Inventory (TCI). No strong evidence was found for the association between TCI personality traits and the polymorphisms considered in the 4 genes, with the exception of an association between reward dependence trait and the rs2682826 SNP in NOS1 in the healthy sample. However, this result could be plausibly interpreted as a false-positive finding. In conclusion, our study did not support the thesis of a direct modulation of these genes on temperament; however, further studies on larger samples are clearly required in order to confirm our preliminary findings and to exclude any possible minor influence.

The Interpersonal Psychological Theory of Suicide in Italian University Students: Validation of the INQ-15 and the ACSS-FAD
No full textIn the frame of the interpersonal psychological theory of suicide (IPTS), Interpersonal Needs Questionnaire (INQ-15) assesses thwarted belongingness (TB) and perceived burdensomeness (PB), related to suicidal ideation (SI); Acquired Capability for Suicide Scale-Fearlessness About Death (ACSS-FAD) measures this component which contributes to lethal self-harm. The objective was to evaluate the psychometric properties of INQ-15 and ACSS-FAD in a population of Italian university students. Since the Italian INQ-15 was already validated, we translated ACSS-FAD through a multistage procedure and administered both to 1,665 Italian university students. Factor analysis confirmed a two-factor-related model of INQ-15, one factor of ACSS-FAD, and good reliability for both. We proved the association between INQ-15 and current SI and between ACSS-FAD and lifetime suicidal planning and/or suicide attempt. The convergent and discriminant validities were in line with those of previous studies. Both tools are valid and reliable to assess the constructs associated with suicide outcomes according to IPTS
