Announcing a new chapter for calcified tissue international & musculoskeletal diseases
No full textThe year 2025 marks the beginning of a significant editorial transition at Calcified Tissue International and Musculoskeletal Research (CTI). We have introduced changes in publication procedures and are delighted to welcome Professor Roland Chapurlat as Associate Editor. Most significantly, we extend our immense gratitude to Professor Stuart Ralston who is stepping down from his long and distinguished leadership of the journal as its joint Editor-in-Chief
Review of the guideline of the American College of Physicians on the treatment of osteoporosis
No full textSummary:This review, endorsed by the International Osteoporosis Foundation and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases, summarizes several failings of the recent guidelines of the American College of Physicians (ACP) on the treatment of low bone density or osteoporosis to prevent fractures.Introduction:The ACP recently issued guidelines for the treatment of low bone density or osteoporosis to prevent fractures.Methods:Literature review and critical review of the ACP guidelines.Results:The guideline is lacking in scope due to the endorsement of treatment based on T-scores rather than fracture risk assessment and in failure to adequately consider anabolic therapies.Conclusions:The ACP guideline appears outdated
Quality of life assessment in musculo-skeletal health
No full textMusculoskeletal disorders affect morbidity, quality of life and mortality, and represent an increasing economic and societal burden in the context of population aging and increased life expectancy. Improvement of quality of life should be one of the priorities of any interventions to prevent and treat musculoskeletal disorders in the ageing population. Two main approaches, namely generic and disease-specific instruments, can be applied to measure health-related quality of life. Among the generic tools available in scientific literature, the short form 36 questionnaire (SF-36) and the Euroqol five item questionnaire (EQ-5D) are two of the most popular questionnaires used to quantify the health related quality of life in people with musculoskeletal disorders. However, because generic tools may not always be able to detect subtle effects of a specific condition on quality of life, a specific tool is highly valuable. Specific tools improve the ability to clinically characterize quality of life in subjects with a specific musculoskeletal disorder, as well as the capacity to assess changes over time in the QoL of these subjects. The recent development of specific tools should help to validate preventive and therapeutic interventions in this field
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
WHO benchmarks for equitable hip-fracture care and osteoporosis treatment in older people
No full textHip fractures cause major morbidity, mortality and long-term disability among older persons worldwide. The World Health Organization has defined two key indicators within the framework of the UN Decade of Healthy Ageing to measure health system performance in providing care for older adults with hip fractures: the proportion who receive surgery within 48 h of fracture; and the proportion who receive pharmacological treatment for osteoporosis post-fracture. This Perspective article, which describes the clinical importance of these indicators, their amenability for adoption and implications for health equity, is based on findings from audits, guidelines and key literature. Numerous evidence-based solutions - for example, fracture liaison services, orhtogeriatric care models and digital tools support hip-fracture management, yet major barriers remain, such as data gaps, system preparedness and pathway variability. New or modified policies developed by national governments, ministries of health and other relevant authorities and tailored to specific geopolitical contexts are urgently needed to enable the implementation of timely surgical care and secondary fracture prevention strategies aligned with the WHO indicators. Improved health information systems to measure performance and to ensure translation to real-world changes in the lives of older people worldwide are of paramount importance.</p
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
