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

No full textAssessment of the knowledge level and experience of healthcare personnel concerning CPR and early defibrillation: an internal survey
No full textBackground: In‐hospital cardiac arrest (IHCA) is a major public health problem with significant mortality. Rapid cardiopulmonary resuscitation and early defibrillation is extremely connected to patient outcome. In this study, we aimed to assess the effects of a basic life support and defibrillation course in improving knowledge in IHCA management. Methods: We performed a prospective observational study recruiting healthcare personnel working at Azienda Ospedaliero Universitaria Pisana, Pisa, Italy. Study consisted in the administration of two questionnaires before and after BLS-D course. The course was structured as an informative meeting and it was held according to European Resuscitation Council guidelines. Results: 78 participants completed pre- and post-course questionnaires. Only 31.9% of the participants had taken part in a BLS-D before our study. After the course, we found a significative increase in the percentage of participants that evaluated their skills adequate in IHCA management (17.9% vs 42.3%; p < 0.01) and in the correct use of defibrillator (38.8% vs 67.9% p < 0.001). However, 51.3% of respondents still consider their preparation not entirely appropriate after the course. Even more, we observed a significant increase in the number of corrected responses after the course, especially about sequence performed in case of absent vital sign, CPR maneuvers and use of defibrillator. Conclusions: The training course resulted in significant increase in the level of knowledge about the general management of IHCA in hospital staff. Therefore, a simple intervention such as an informative meetings improved significantly the knowledge about IHCA and, consequently, can lead to a reduction of morbidity and mortality
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

No full textA genetic dissection of antipsychotic induced movement disorders.
No full textBACKGROUND:
Antipsychotic medications (APM) are the first line pharmacological treatment for psychotic disorders and other behavioral disorders. Nevertheless, their use causes a number of side effects, including extrapyramidal symptoms (EPS). EPS decrease the efficacy of the antipsychotic treatments by causing poorer compliance to the treatment, stigma and a poorer quality of life for patients. Genetic studies hold the potential to unravel the molecular underpinnings of the EPS induced by APM but results are not conclusive and are far to be used in clinical practice despite decades of research. A more sophisticated selection of the list of genetic mutations explaining the genetic variance of EPS induced by APM could help in the definition of a personalized treatments for patients. Moreover, it would increase the quality of the current treatments with APM.
METHODS:
We reviewed the literature searching for the genetic association studies focused on dystonia, parkinsonism, akathisia and tardive dyskinesia. Moreover, we reviewed the current biological knowledge of the APM induced side effects. Finally, we provide a reasoned list of candidate genes and their genetic variations, with the aim of identifying a list of candidates for APM induced EPS genetic investigations.
RESULTS:
Variations located within PIK3CA (phosphoinositide-3- kinase, catalytic, alpha polypeptide), PLA2G4A (phospholipase A2, group IVA, cytosolic, calcium-dependent), PRKCA (protein kinase C, alpha), PRKACG (Phosphatidylinositol-4,5-bisphosphate 3-kinase 110 kDa catalytic subunit gamma), ERK-1 (extracellular signalregulated kinase 1 (MAPK3)), ERK-2 (extracellular signal-regulated kinase 2 (MAPK1)), GNAS (guanine nucleotide binding protein (G protein), alpha stimulating activity polypeptide 1), PLCB1 (phospholipase C, beta 1 (phosphoinositide-specific)) and ITPR1 (inositol 1,4,5-triphosphate receptor type 1) were found to be relevant for APM induced EPS. Some of the genes are classical candidates for this kind of research, others were never investigated. For each of these genes we provide a list of variations that balances the limitations of multitesting with the advantages of the tagging approach.
CONCLUSIONS:
We undertook a review of the literature about the APM induced EPM to provide some rational genetic candidates to be tested in further genetic investigations
The molecular interaction between the glutamatergic, noradrenergic, dopaminergic and serotoninergic systems informs a detailed genetic perspective on depressive phenotypes.
No full textThe glutamatergic pathway has been consistently involved in the physiopathology of depressive disorder. However a complete dissection and integration of its role in the context of other known mechanisms is lacking. We summarized and integrated the evidence of various levels of interaction between glutamatergic and monoaminergic pathways (see videos). We identified six molecular pathways, some of which with specific regional distribution within the brain. From the six pathways we identified the key proteins and their coding genes, we then provided a detailed list of possible candidates with practical suggestions for association studies planning
