The interdisciplinary approach to the treatment of multiple sclerosis patients in Italy: an aspiration or a reality?
No full textThe aim of the study was to assess whether the components necessary for an interdisciplinary approach to the treatment of multiple sclerosis (MS) patients exist in Italian MS clinics and to identify factors that make the difference between reality and aspiration for this type of approach. One hundred two out of 147 neurology departments with MS clinics throughout Italy compiled a questionnaire about characteristics and organizational structure of the clinic, type and number of professionals and resource needs. Eight hundred twenty-three healthcare professionals are currently working in MS clinics: 50% (412) neurologists, 28.7% (236) nurses, 15.1% (124) physical therapists, 3.4% (28) psychologists and 2.8% (23) social workers. Neurologists are evenly distributed between northern and southern parts of the country even though there are nearly double the number of patients followed in northern clinics compared to those in the south. Physicians reported themselves as most in need of continuing education, twice that which the same physicians reported for any other professional. The study has identified issues that contribute to the difficulty in developing and applying an interdisciplinary approach to providing care and services to Italian MS patients. Several factors have been delineated that require significant reshaping in order for this approach to begin to develop
A cost evaluation of multiple sclerosis
No full textAs a chronic and disabling disease, multiple sclerosis (MS) is extremely costly, both for the individual and the family, as well as for the society. Early onset, long duration and effects on employment contribute to the extensive costs related to the illness. Thus far, studies conducted in developed countries have demonstrated that direct costs, including treatment (prior to the approval of beta interferon), medical visits, hospitalization, assistance, etc., are much lower in respect to indirect costs, such as loss of income from reduction of work activity for patients and carers, which account for up to 75% of the total cost. Informal care represents a heavy burden for the families of disabled persons and little is known about the 'intangible' costs of MS, such as those related to the influence of the disease on quality of life. In addition, the cost/benefit ratio for expensive new therapies, such as beta interferon, remains to be determined
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
Pharmacodynamics, clinical findings and approval status of current and emerging tyrosine-kinase inhibitors for pancreatic neuroendocrine tumors
No full textIntroduction: Pancreatic neuroendocrine tumors (panNETs) represent a rare group of malignancies. For decades, chemotherapy, somatostatin analogs and interferon represented the only systemic therapies; however, over the latest years, new options were registered, including Everolimus, Sunitinib (SUN), and Peptide Receptor Radionuclide Therapy. Areas covered: This review discusses the role of tyrosine kinase inhibitors (TKIs) in advanced panNETs. Expert opinion: TKIs showed an antiangiogenic and antiproliferative impact on advanced panNETs. Sunitinib is the only TKI currently available in clinical practice, having been approved on the basis of relevant results of a specific panNET phase III trial. New TKIs, such as Cabozantinib, Lenvatinib, Pazopanib, Surufatinib are still on investigation in panNETs. Although some phase II studies with the new TKIs yielded better PFS and RR compared with SUN, different study designs and tumor populations may have induced selection biases. However, it was reported that panNETs resistant to SUN could respond to a new TKI, indicating a possible further therapeutic line in this context. The global investigation plan of TKIs in panNETs is not homogeneous and it is difficult to understand what kind of development this can have in the near future for clinical practice
