A randomized controlled trial of relaxation training to reduce hot flashes in women with primary breast cancer
Hot flashes are experienced by about 52% of perimenopausal women. After breast cancer, this may increase to 70%. The use of hormone replacement therapy is not recommended in women who have had breast cancer; therefore, alternatives are required to help relieve hot flashes. This study was conducted to assess the efficacy of relaxation training in reducing the incidence of hot flashes in women with primary breast cancer. This was a randomized controlled trial of 150 women with primary breast cancer who experienced hot flashes. The intervention group received a single relaxation training session and was instructed to use practice tapes on a daily basis at home for one month; the control group received no intervention. Outcomes were incidence and severity of flashes using a diary and validated measures of anxiety and quality of life. The incidence and severity of hot flashes, as recorded by diaries, each significantly declined over one month (P<0.001 and P=0.01, respectively), compared with the control group. Distress caused by flashes also significantly declined in the treatment group over one month (P=0.01), compared with the control group. There were no significant differences between the treatment group and the control group at three months and no changes in anxiety or quality-of-life measures. Relaxation may be a useful component of a program of measures to relieve hot flashes in women with primary breast cancer
Listening to the views of people affected by cancer about cancer research: an example of participatory research in setting the cancer research agenda
Aim The study 'Listening to the Views of People Affected by Cancer About Cancer Research' is currently exploring the views people affected by cancer have about cancer research and identifying their research priorities. Integral to this is the broader aim of ensuring an effective, collaborative participation of patients and carers in the design and conduct of the study. On the basis of experiences with the study to date, the latter is explored in this paper.Design The study adopts a 'participatory research' approach entailing the formation of a 'reference group' and a subsequent patient and carer co-researcher group. Patient and carer members of these groups were identified through the patient forums of UK cancer networks and by approaching 'hard to reach' representatives directly through community groups and participating study sites.Findings Experiences from this study illustrate that a 'participatory research' approach is appropriate in engaging patients and carers in the research process. Establishing a group of people affected by cancer in the study was found to be particularly effective in enhancing the design and conduct of the research.Conclusions 'Participatory research' offers an effective means of involving patients and carers throughout the research process, thus strengthening the relevance and appropriateness of research findings and methods
Nurse-led models of chemotherapy care: mixed economy or nurse–doctor substitution?
Aim: This paper reports a study exploring the perspectives of people affected by cancer (service users) and health care professionals' about current medical consultant-led services and the acceptability of a proposed nurse-led ambulatory chemotherapy service.Background: A number of studies have evaluated a nurse-led model of cancer care delivery but little work has been undertaken in chemotherapy settings. Furthermore, many of these studies give little information on how the perspective of users was incorporated in the design and evaluation of these services.Methods: Service users (n = 26) and health care professionals (n = 22) were recruited across the South East of England. A qualitative study was undertaken… Using a semi-structured interview schedule, participants were asked to give their perceptions of current chemotherapy services and the potential of a nurse-led service. A thematic analysis of data was undertaken.Findings: This paper focuses on the theme of the current and future context of a chemotherapy service. Three sub-themes were identified: contextualizing roles, defining therapeutic outcomes, and demonstrating effectiveness. All interviewees saw this role as different but complementary to the role of medical staff. There were mixed opinions from service users and professionals on the acceptability of nurse-led chemotherapy provision. In defining potential outcomes of nurse-led care, service users described benefits in terms of service and economic outcomes. Professionals saw additional benefits in terms of patient-based outcomes. Professionals and service users expressed the need for appropriate education of nurses for this role and rigorous evaluation of any new service before widespread implementation.Conclusions: Understanding the perspective of users is imperative when re-designing cancer nursing services. Implementation of nurse-led models in chemotherapy services should be preceded by staff education and followed by systematic evaluation
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
