[Diabetic foot infections]
No full textInfection of diabetic foot represents one of the most serious complications of diabetes. Deep infections of the foot, due to the compartment structure of the foot, can cause severe infective compartment syndromes that pose the diabetic patient to very high risk of major amputation and sepsis. The treatment of choice of this severe infective condition is represented by an aggressive surgical debridement with the aim to drainage pus and to remove infective and non vital tissue. Surgical debridement has to be performed as soon as possible since any delay corresponds to an increase of the risk of major amputation and death for sepsis. In case of concomitant severe peripheral vascular disease any revascularisation procedures, surgical or endoluminal, have to be performer once the local and systemic infection has been controlled
Activity of ulifloxacin against clinical hospital isolates
No full textWe evaluated the activity of ulifloxacin in comparison with ciprofloxacin, levofloxacin and moxifloxacin against clinical isolates from a large teaching hospital in Italy. The isolates derived from patients admitted to surgical and medical wards and intensive care units. Multi-drug resistant S. aureus, P. aeruginosa, enterococci and Enterobacteriaceae spp. strains were included in the study. Ulifloxacin was slightly more active than ciprofloxacin and levofloxacin against gram negative isolates. Against gram positive strains ulifloxacin was as active as moxifloxacin
The Elephant in the Room
No full textDespite its increasing prevalence, severity, and mortality, Diabetic foot syndrome (DFS) still remains an unaddressed critical issue. The management of DFS is adequately performed only in few centers, and clinical outcomes vary, depending on the possibility of patients to access optimal standards of care. To focus on the critical aspects of the management of DFS in Italy with the purpose of suggesting arguments that might have a more general audience, to improve the quality of therapy and accessibility to optimal care, we have written this article
Non-reversed bifurcated vein graft improves time to healing in ischemic patients undergoing lower limb distal bypass
No full textBifurcated vein grafts have been described in reconstructive microsurgery. No comparative studies have been published in lower limb arterial revascularization. The aim of this study was to compare non-reversed bifurcated vs. single vein graft in patients with critical limb-threatening ischemia (CLTI) undergoing lower limb distal bypass

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
