Undernutrition, Sarcopenia, Sarcopenic Obesity, and Sarcopenic Undernutrition: A Cross-sectional View on Patients before Total Joint Arthroplasty
Full text linkDiagnostic criteria of malnutrition phenotypes have been recently updated. Uncovering the prevalence of these conditions in patients undergoing hip replacement may be crucial in order to apply the most appropriate diagnostic-therapeutic paths to the right patient at the right time. Sixty patients aged between 60 and 85 undergoing elective hip replacement were recruited. Preoperative measures concerning eating behaviors, anthropometry, physical performance, laboratory parameters, and patient reported measures of pain and function were collected, used to make diagnosis, and explored whether they differed based on malnutrition categorization. Patients undernourished were 18.75%, sarcopenic 13.34%, sarcopenic obesity 4.26%, and 8.88% undernourished and sarcopenic. Well-nourished patients ate more cereals and meat, exhibited lower white blood cells but higher lymphocytes, and reported greater hip-related pain. One in three older patients undergoing elective hip replacement was malnourished. Eating behaviors and leucocytes were the discriminating factors between malnourished and well-nourished. It remains to be established whether malnutrition affects outcome after surgery
Association between inspiratory muscle function and balance ability in older people: a pooled data analysis before and after inspiratory muscle training
No full textInspiratory muscle training (IMT) improved balance ability and respiratory muscle function in healthy older adults. The current study is a retrospective analysis to explore the relationship between inspiratory muscle function, balance ability, and adaptation to IMT. All participants (total = 129; IMT = 60; age range = 65–85 years) performed inspiratory and balance assessments, including the mini-balance evaluation system test, maximal inspiratory pressure, and peak inspiratory flow tests. Baseline inspiratory muscle function was positively related to balance ability (p < .05), and IMT-induced improvements in inspiratory function (23.3% in maximal inspiratory pressure, 8.0% in peak inspiratory flow rate, 14.9% in maximal peak inspiratory power) were related to improvements in balance (10.6% in mini-balance evaluation system test), with the greatest improvements (17.0%) observed in the oldest participants (76–85 years old, p < .05). In conclusion, with or without IMT, positive associations between inspiratory function and balance ability exist, with greater improvements in inspiratory muscle function related to greater improvements in balance ability
Understanding the patient perspective when designing future rehabilitation interventions after hip or knee replacement surgery—a patient and public involvement exercise
Full text linkBackground and objectives: following discharge from hospital, there can be variability in the rehabilitation of patients who have undergone total hip or knee replacement surgery. We invited patients who had had hip or knee replacement surgery to take part in patient and public involvement sessions to help us understand their recovery needs and how rehabilitation services could potentially be improved to meet these needs better. Materials: patients (n = 14) were invited to one of two patient advisory group sessions which took place in a university setting. Results: feedback from patients highlighted the need for an inclusive, evidence-based intervention that would benefit patients experiencing all levels of pain, with differing motivations for recovery. Patients desired social support with others who have had similar surgery to reduce the burden of isolation during rehabilitation. Furthermore, patients valued the involvement of their partners and carers in their rehabilitation, to provide social support and guidance on recovery. Patients also expressed a need for consistent information and expert guidance on all aspects of their recovery. Conclusions: these findings can be used to guide the design of rehabilitation interventions following hip and knee replacement and ensure that patient perspectives inform future practice
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
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
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
