Increased dopaminergic activity in restricting-type anorexia nervosa
No full textEye blink rate, a peripheral measure of central dopaminergic activity, has been investigated in 20 female anorexic "restricting-type" patients and 16 healthy female subjects. A significantly increased blink rate was found in the anorexic patients. A significant positive correlation between blink rate and duration of illness was also found
Prognostic factors and outcome in anorexia nervosa: a follow-up study
No full textAnorexia nervosa is an eating disorder characterized by food restriction, irrational fear of gaining weight and consequent weight loss. High mortality rates have been reported, mostly due to suicide and malnutrition. Good outcomes largely vary between 18 and 42%. We aimed to assess outcome and prognostic factors of a large group of patients with anorexia nervosa. Moreover we aimed to identify clusters of prognostic factors related to specific outcomes
Severe acute liver damage in anorexia nervosa: two case reports.
No full textObjective: Two female patients (18 and 30 y old, body mass indexes 14.1 and 13.2 kg/m2) with
severe, restrictive anorexia nervosa developed sudden severe liver damage. In addition to overt
protein-energy malnutrition, they showed marked hypotension, bradycardia, dry skin, acrocyanosis,
and hypothermia. Most common causes of liver failure, such as hepatotropic viruses, hepatotoxic
drugs, alcohol, cannabis, and cocaine abuse, were excluded.
Methods: Therapeutic intervention consisted of immediate plasma volume support, progressive
parenteral or oral nutritional rehabilitation, and parenteral potassium and phosphorus supplements
to avoid the refeeding syndrome.
Results and conclusion: Improvement of initial clinical symptoms and rapid recovery of liver
enzymes after this type of treatment suggest that severe liver damage in anorexia nervosa may be
secondary to acute hypoperfusion
Nutrimento, Intrusione, Abuso: un continuum nella definizione dei limiti del corpo
No full textIl manuale affronta il tema dei rapporti fra cibo e sessualità dal punto di vista biologico, psicologico e culturale. Dal punto di vista biologico, è innanzitutto necessario conoscere e comprendere: - i sofisticati sistemi neuroregolatori dell'attività sessuale, nell'uomo e nei modelli animali; - gli ormoni sessuali, il loro metabolismo e le modalità d'azione; - i meccanismi della fertilità e della procreazione, legate a equilibri nutrizionali oggi in grave pericolo. Dal punto di vista clinico, il fenomano più frequente è quello dell'anoressia sessuale, che ha basi biologiche e psichiche e che può giungere al rifiuto del partner
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
Drop-out rate in eating disorders: could it be a function of patient-therapist relationship?
No full textOBJECTIVE: The factors influencing drop-out in eating disorders (ED) are still unclear. The aim of the present study was to determine whether compliance is strongly related to the patient-therapist relationship. MATERIALS AND METHODS: During 14 months all new patients affected by EDs referring to our Specialist Service Center, were assessed and followed up, they underwent EAT 40, EDI II, and computerized case history for ED. Moreover, we collected data from therapist using the GCI scale, and we recorded as the patient perceived his weight (PPW). RESULTS: We found that out of the 100 patients enrolled, 53 withdraw and when probability was predicted according to a digit model, it was not influenced by EDI-II subscales, age, sex, education, EAT-40 score, duration of the disorder and diagnosis while it significantly decreased when GCI scores increased and decreased when the PPW was altered. CONCLUSION: These results seem to confirm that some psychological factors related to patient-therapist relationship can play a key role for a stable and continuous therapeutic program
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
