Alexithymia and eating behaviour in severely obese patients.
No full textBackground: Alexithymia is the inability to express feelings with words and comprises a psychological construct frequently found in obese individuals. In eating disordered patients who show a tendency to lose control over food
intake, personality traits with alexithymic characteristics have been demonstrated.The present cross-sectional study investigated the relationships between alexithymia and eating behaviour in severely obese patients.Methods: This study analysed 150 obese patients undergoing bariatric surgeryand 132 subjects at more than 1 year after biliopancreatic diversion (BPD),when body weight has steadily normalised and any preoccupation with weight,
food and diet has been completely abandoned. Obese and operated subjectscompleted the Toronto Alexithymia Scale (TAS), and eating behaviour was assessed via a semi-structured interview exploring binge eating disorder (BED),
night eating and emotional eating, as well as by utilisation the Three Factor
Eating Questionnaire (TFEQ).Results: Although alexithymic patients showed deranged eating behaviour, as
evaluated by the TFEQ scores, the frequency of BED, night eating and emotional eating was similar in alexithymic (TAS > 60) and non-alexithymic patients. However, the prevalence of alexithymia was similar in obese and BPD
subjects, whereas, in the operated subjects, TFEQ scores were lower (P < 0.005) than those in obese patients.
Conclusions: These data suggest that, in severely obese patients, alexithymia does not influence eating behaviour; in severely obese patients, the tendency tolose control over food intake apparently represents a psychological construct
that is substantially independent from alexithymia
Do clinical and behavioural correlates of obese patients seeking bariatric surgery differ from those of individuals involved in conservative weight loss programme?
No full textBACKGROUND: Clinical practice has suggested that, in severely obese patients seeking bariatric surgery, clinical conditions, behavioural characteristics and psychological status might all differ from those of their counterparts starting conventional conservative therapy.
METHODS: Two groups of obese patients with closely similar body mass values were considered. The first group included individuals voluntarily and spontaneously seeking biliopancreatic diversion and the second group comprised patients at the beginning of a weight loss programme. After anthropometric and metabolic evaluation, the patients underwent an alimentary interview; eating behaviour and psychological status were assessed by Three Factor Eating Questionnaire and by Toronto Alexithymia Scale (TAS).
RESULTS: Among bariatric candidates, a greater number of individuals with type 2 diabetes and dyslipidaemia and high tendency to disinhibition and susceptibility to hunger scores was observed, whereas the other aspects of eating pattern were essentially similar. In the two groups, no difference in TAS score and or number of patients with alexithymic traits was observed. Finally, a logistic regression model showed that only age and metabolic derangement predicted the bariatric option, whereas eating behaviour or psychological status did not influence individual therapeutic choice.
CONCLUSIONS: Independently of the degree of obesity, bariatric surgery was requested by the more metabolically deranged patients, whereas, in the surgical candidates, the eating pattern and psychological conditions were very similar to those of obese persons at the beginning of a conservative weight loss programme. These results suggest a highly realistic and practical attitude in severely obese patients towards obesity and bariatric surgery
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
