Rehabilitation in COPD patients admitted for exacerbation
Full text linkRecovery of lung function is delayed up to 2 months following acute exacerbation (AE) of COPD patients. After AE, even with optimal medical therapy, it takes considerable time for COPD patients to recover to baseline ability to perform usual physical activity.Despite pulmonary rehabilitation (PR) has been so far considered a useful non-pharmacological therapy in stable COPD individuals, still few studies have examined the effect of rehabilitation during and/or early after AE.The present review updates the application of early PR and main physical therapies both during hospital acute care and following discharge of COPD patients undergoing exacerbation.Only recently, literature has shown feasibility and effectiveness of early PR in COPD patients undergoing AE. Notwithstanding, it clearly appears a treatment indicated just after or even during an acute episode in hospital.Future studies should be able to clarify the practical role and effects of a timely application of rehabilitation to acute COPD, as well as the preferred modalities, duration and techniques to apply in this condition

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
Co-morbidities in chronic respiratory patients: limitations or opportunities for caring ?
No full textIn the population of chronic respiratory patients a new subset with clinical complexity and with multiple coexisting organ failure and diseases is rapidly growing. Mainly due to the aging process, the associated frailty - not strictly related to the patient’s age - consists in a progressive and physiologic decline in multiple body systems leading to a substantial loss of functions and physiologic reserve. It is commonly acquainted that frailty, co-morbidities (several medical conditions associated) and disability (decline in physical functions) overlap each other: both frailty and co-morbidities can predict physical disability, whereas disability per se may exacerbate frailty and co-morbidities. Specific interventions (as rehabilitation) targeting at the physical activity the old population have been shown to improve physical function and have a benefit along the full spectrum of health status. However, there is a substantial need for a multidimensional and personalized care approach: patient’s complexity, in fact, may play a role in determining the patient’s response to treatment. In particular, each disease as a single entity might reduce the response to treatment, depending on its effect on body functions and target therapies. Notwithstanding, the clinical complexity of these patients and the presence of several co-morbidities, does not preclude per se the application and the effectiveness of a comprehensive rehabilitation program targeted to the individual’s needs
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
