Chronic inflammatory liver diseases and coffee intake
To review the healthy protective effects of coffee against several metabolic diseases and some types of cancer. In this short review, the possible preventive and/or therapeutic actions of coffee on liver function is focused
Clozapine treatment and other atypical and typical antipsychotics: incidence and course of blood dyscrasias during the first eighteen weeks of treatment
Blood dyscrasias induced by clozapine treatment and other Typical and Atypical Antipsychotics have received little attention. The aim of the present study was to shed more light on the incidence and course of clozapine-induced blood dyscrasias that occour during the first eighteen weeks of treatment compared to dyscrasias induced by other Typical and Atypical Antipsychotics. The study included 135 clozapine-treated patients (M 75 and F 60), 75 patients treated with other Atypical (M 35 and F 40), and 75 treated with Typical (M 39 and F 36). Persistent eosinophilia appeared in 36.8% of clozapine-treated patients, in 4%, (p<.05) and 2.7%, (p<.05), respectively, of patients treated with Atipical and Typical Antipychotics; persistent leukocytosis, instead, appeared in 26.5% of patients treated with clozapine, 13.3% and 18.7% treated, respectively, with Atypical and Typical. Moreover, persistent neutrophilia appeared in 27.2% of subjects treated with clozapine, 12.0% with Atypical and 10.7%, (p<.027) with Typical. Our data report an incidence of persistent anemia in clozapine-treated patients of 45.6% (62/136) with respect to 8% (6/75), (p<.05) of patients treated with Atypical and 12% (9/75), (p<.05) with Typical. Our study report sex-correlated differences in clozapine-treated patients, with a major incidence of persistent anemia among female patients (p<.001). Our data could be offered to alert clinicians to the possibility that hematologic complications may be more common in patients treated with clozapine than in patients treated with other antipsychotics
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Nutrition transition and cancer
Urbanization, population aging, and climatic changes have mostly contributed to nutrition transition and, consequently, to effects of food habits on the epidemic of chronic non-communicable diseases (NCDs), especially cancer. Climatic changes are negatively affecting crop production, particularly biodiversity, leading to reduced food choices and, consequently, nutritional value and the protection conferred from consumption of a variety of nutrients essential in a healthy diet. This brief review analyzes the possible link between rapid demographic changes, climatic and environmental crises, and the current food system as possible factors contributing to the role of nutrition transition in the onset of cancer
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
