Disuguaglianze nella qualità dell'assistenza alla popolazione adulta con diabete mellito della Regione Marche: lo studio AEQUITAS
No full textIl diabete è uno dei principali problemi di salute pubblica internazionale. La letteratura
riporta la presenza di disuguaglianze di salute nella qualità dell’assistenza alle persone
diabetiche, ma non vi sono dati riguardanti i servizi offerti nella realtà regionale. Utilizzando i
dati dei database di 52 medici di medicina generale (MMG) e i dati amministrativi di utilizzo
dei servizi sanitari regionali, il progetto di ricerca si pone l’obiettivo di valutare le differenze
sociali e geografiche nell’appropriatezza del processo di cura del diabete mellito e stimare la
prevalenza del diabete nella Regione Marche.
All’interno del campione di 65 696 assistiti dai MMG sono stati identificati 6 494 diabetici nel
periodo 2003-2010, per i quali è stata valutata l’appropriatezza delle cure prestate
analizzando l’associazione tra due indicatori di appropriatezza, uno di esito (i ricoveri
prevenibili per diabete, definiti secondo l’AHRQ) e uno di processo, la frequenza di controlli
dell’emoglobina glicata (A1C) per ogni anno di osservazione e le variabili cliniche, strutturali e
socioeconomiche dei soggetti.
La prevalenza del diabete varia dal 5.4% nel 2003 al 7.8% nel 2010, con un significativo trend
annuo in aumento indipendentemente dall’invecchiamento della popolazione regionale. I
soggetti diabetici di età compresa tra 20 e 44 anni sono a maggior rischio sia di
ospedalizzazione prevenibile sia di discontinuità nell’effettuare i controlli di A1C. Entrambi gli
indicatori non si sono dimostrati influenzati dallo status socioeconomico dell’individuo,
misurato dal livello di istruzione. La deprivazione del luogo di residenza ha un effetto
favorente i ricoveri prevenibili e la discontinuità dei controlli nei soggetti con età maggiore di
45 anni. La deprivazione si è dimostrata un fattore indipendente protettivo per la
discontinuità dei controlli, spiegabile dalla presenza di servizi specialistici diabetologici in
molti comuni deprivati o molto deprivati. I risultati indicano la presenza di condizioni di
vulnerabilità nella qualità dell’assistenza ai soggetti diabetici che richiede maggiori sforzi da
parte di tutti gli attori del Sistema Sanitario Regionale
Comparison of liver fibrosis progression in HIV/HCV co-infected and HCV mono-infected patients by transient elastometry
No full textMonitoring of liver fibrosis (LF) is an essential tool for preventing liver-related complications in HIV/HCV co-infected patients. In this study, we compared LF progression by transient elastometry (TE) in 50 HIV/HCV co-infected and 115 HCV mono-infected patients followed in our institution between June 2006 and December 2011. Patients naive to interferon therapy and with at least two measurements of liver stiffness by TE were included. In all, 76% of HIV/HCV co-infected and 75% of HCV mono-infected patients remained in the same stage of LF over time. Conversely, 19% and 15% of HIV/HCV co-infected and HCV mono-infected subjects, respectively, had progression to advanced LF (≥ F3). Our study found a similar proportion of HIV/HCV co-infected and HCV mono-infected patients that developed an advanced LF during the follow-up time considered. Alcohol abuse was the only factor significantly associated with the progression as evidenced by multiple quantile regression analysis
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
