Fertility preservation in cancer patients : The global framework
Get PDFCancer treatment is the most frequent cause of reduced fertility in cancer patients, with up to 80% of survivors affected. None of the established or experimental fertility preservation methods can assure parenthood, rather they may provide a future opportunity to overcome treatment induced sterility. Around 70-75% of young cancer survivors are interested in parenthood but the numbers of patients who access fertility preservation techniques prior treatment are significantly lower. Moreover, despite existing guidelines, healthcare professionals do not address fertility preservation issues adequately. Lack of time and knowledge about existing options, delay in potentially useful treatment, patient's age, partnership status, existing children, sexual orientation and socioeconomic situation are the main barriers to effective fertility preservation. Patient's fears, expectations and priorities shaped by personal values have to be addressed in the framework of medical necessities, realistic survival probabilities, socio-cultural environment and resources availability. We call for a need of patient centred fertility counselling within a framework that should include patients understanding of medical aspects of their cancer, realistic fertility preservation options, preferences based on personal values and goals. Optional support services could also include legal guidance, psychological and spiritual support and financial counselling
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
Functional living skills assessment: a standardized measure of high-order activities of daily living in patients with dementia
No full textAim. Performance measures are tools aimed to directly evaluate social function in older adults. The authors present the standardization of a new direct performance measure for patients with dementia, the functional living skills assessment (FLSA).
Methods. FLSA was conceived to detect functional impairment in very mild to moderate patients and to pick up functional modification due to intervention. The patient is asked to perform an activity, and the performance is scored according to completeness and level of assistance required. Eight areas of interest are evaluated (Resources, Consumer Skills, Public Transportation, Time Management, Money management, Leisure, Telephone Skills, Self-Care and Health). Subjects included 54 patients with dementia and 36 normal controls. Results. Total and partial FLSA scores significantly differed for the two groups (P0.9). Correction scores for education were calculated, while age influence was only marginally significant. Mini Mental State Examination (MMSE) and CDR highly influenced FLSA score (P< 0.0001); FLSA was highly correlated with another performance measure (the Direct Assessment of Functional Status; P=0.821), and with the Instrumental Activity of Daily Living (IADL) scale (P=-0.612), while no significant correlation was present with the Geriatric Depression Scale.
Conclusion. FLSA evidences construct, concurrent and discriminative validity. We suggest that this tool could be possibly useful when a high sensibility to different levels of functional impairment is needed, as evaluation of treatment efficacy (both non-pharmacological and pharmacological) identification of relatively intact functional areas to plan cognitive rehabilitation, and confirmation of dementia in the initial phase when there are doubts about functional decline
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
