La Qualità della Vita (QoL) in soggetti affetti da obesità di grado elevato: ruolo dell’Educazione Terapeutica (ET)
No full textPremesse: recenti revisioni della letteratura dimostrano che il decremento ponderale è correlato ad un
significativo miglioramento della QoL, valutata attraverso SF36, sotto il profilo somatico ma non mentale, con
possibili ripercussioni sull’esito del trattamento a medio e lungo termine.
Obiettivi: valutare, attraverso uno studio pilota, il ruolo di un intervento di gruppo multidisciplinare, definito
Educazione alla Scelta e Consapevolezza, basato sui principi dell’ET (Report of a WHO Working Group
1998), nell’aiutare i pazienti obesi, con o senza binge eating, a migliorare i propri comportamenti alimentari e
la QoL.
Metodi: 70 soggetti obesi (13M-45,9±9,8aa-BMI43,4±8,4kg/m2; 57F-46,5±11,2aa-BMI42,4±7,4kg/m2) sono
stati reclutati presso il C.A.S.C.O.; sono stati rilevati colesterolo totale, C-LDL, C-HDL,trigliceridi e glicemia
e analizzate le abitudini alimentari mediante FFQ; è stato delineato il profilo psicologico attraverso test SCL90
e BES e valutata la QoL attraverso SF36. Tutti i parametri sono stati valutati all’arruolamento (T0) e dopo 8
incontri di gruppo di ET a cadenza quindicinale (T8). Le differenze sono state confrontate assumendo un p
value < 0.05.
Risultati: al T8 si osserva un significativo miglioramento di tutti i parametri ematochimici esaminati e dello
score SF36 in entrambe le aree della QoL, somatica (57,1±23,4 vs 67,9±21,1) e mentale (58,7±21,7 vs
71,6±21); le scale di somatizzazione, ossessione-compulsione, ipersensibilità interpersonale e depressione
dell’SCL90, che al T0 presentano uno score >1 (patologico) risultano normalizzate, e lo score BES, borderline
al T0 (17,1±9,1) migliora significativamente al T8 (8,3±7,18); l’eccessivo consumo di alimenti di origine
animale e dolci si riduce significativamente, mentre aumenta l’assunzione di pesce, legumi, ortaggi e frutta,
sebbene il decremento ponderale risulti di soli 3,2±4,16 kg (BMI -1,19±1,55 kg/m2), senza differenze
statisticamente significative tra i 2 sessi.
Conclusioni: il percorso di ET ha determinato un significativo miglioramento della QoL, sia sotto il profilo
mentale che somatico, nonché delle abitudini alimentari. Tale risultato assume particolare rilevanza in
relazione al modesto decremento ponderale, riconducibile alla scarsa motivazione e dichiarata resistenza che i
soggetti hanno mostrato all’intervento dietoterapico. Occorre sottolineare la necessità di ottimizzare
l’integrazione del lavoro di nutrizionisti e psicologi, individuando nuove strategie d’intervento dietoterapico,
incentrate sul counseling, da utilizzare durante il percorso di ET
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
Dieta, infiammazione e malattie metaboliche
No full textLa disponibilità di cibo e l’esposizione ad agenti
patogeni hanno condizionato l’evoluzione della specie
umana favorendo l’acquisizione di un’elevata efficienza nell’accumulare energia e lo sviluppo di un efficace apparato
di difesa, rappresentato dal sistema immunitario. Il network
che connette funzioni metaboliche e immunitarie si è strutturato
in un contesto diverso da quello odierno, cosicché l’attuale
l’overload metabolico induce uno stato infiammatorio
cronico di basso grado.The availability of food and the exposure to pathogen agents influenced the evolution of the human species promoting the acquisition of an high efficiency in energy storage and the development of an effective defense system, represented by the immune system. The network connecting metabolic and immune functions is structured in an environmetal context different from today, so that the current metabolic overload induces a chronic low grade inflammatory status
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
