Better outcomes after minimally invasive surgeries compared to the standard invasive medial parapatellar approach for total knee arthroplasty: a meta-analysis
Purpose: Minimally invasive surgery (MIS) for total knee arthroplasty (TKA) is often marketed as being able to speed up healing times over standard invasive surgery (SIS) through the medial parapatellar approach. The advantages of these minimally invasive approaches, however, are not yet definitively established. A meta-analysis of studies comparing peri-operative and post-operative differences and long-term complications of MIS versus SIS for TKA was conducted. Methods: This meta-analysis was conducted following the PRISMA guidelines. The Pubmed, Google Scholar, Scopus, and Embase databases were accessed in September 2020. All clinical trials comparing minimally-invasive versus standard approaches for TKA were considered. Only studies reporting quantitative data under the outcomes of interest were included. Methodological quality assessment was performed using the PEDro appraisal score. Results: This meta-analysis covers a total of 38 studies (3296 procedures), with a mean 21.3 ± 24.3 months of follow-up. The MIS group had shorter hospitalization times, lower values of total estimated blood loss, quicker times of straight-leg raise, greater values for range of motion, higher scores on the Knee Society Clinical Rating System (KSS) and its related Function Subscale (KSFS). Pain scores, anterior knee pain and revision rate were similar between MIS and SIS. SIS allowed a quicker surgical duration. Conclusion: The present meta-analysis encourages the use of minimally invasive techniques for total knee arthroplasty. However, MIS TKA is technically demanding and requires a long learning curve. Level of evidence: III, meta-analysis of clinical trials
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
Co-creating a Social Innovation Research Agenda for Europe.
As part of the Social Innovation Europe initiative, EMES was asked to produce a research agenda on social innovation (SI). To date, SI practice has been ahead of theory, but research has been catching up in recent years, partly owing to increased interest (and investment) from research funding bodies. It is widely acknowledged that SI research and practice need to be better linked through a mutual recognition of their different purposes in contemporary society. Thus, our goal is to give researchers the opportunity to co-create a future research agenda in collaboration with other stakeholders.
Instead of taking the easy way to do this (simply doing an updated literature review and listing a number of topics that we believe to be relevant to SI research), EMES decided to embark in a co-creation process inviting academic stakeholders across Europe. It was an experiment that had never been tried before with such meagre resources but it was an intense learning exercise whose result is included here.
Essentially, the SIE research agenda aims at building a community that shares the purpose to identify approaches to study SI free from instrumental objectives. Research approaches represent different perspectives on how SI can be studied: as an aspect of an evaluation process, a policy area, an organisation, a technological trend. In order to reach this objective we identify a selective number of topics and actions, covering different types of topics based on past and future consultations, which are by no means exhaustive: stages in a process, policy fields, communities etc. We then use these to highlight possible approaches to study or further the study of SI - where we stand with research on these topics and what is necessary
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
International approaches to orthopaedic sports injury education: Advancing clinical practice through global collaboration
Sports injuries represent a growing global health challenge, placing substantial demands on healthcare systems and requiring multidisciplinary management. As orthopaedic sports trauma becomes increasingly complex, high-quality education and standardised training are essential to improve prevention, diagnosis, and treatment outcomes. This narrative review aims to analyse current educational models and training pathways in orthopaedic sports injury management worldwide, evaluate the role of technological innovations, and highlight opportunities for international collaboration to enhance clinical practice and education. A wide spectrum of training methods is currently employed, ranging from traditional time-based models to modern competency-based curricula. Innovations such as virtual and augmented reality, simulation-based learning, and e-learning have demonstrated promising results in surgical skill acquisition and knowledge retention. International fellowships and consensus frameworks further contribute to the harmonisation of training standards. However, disparities persist in access to educational resources, healthcare infrastructure, and implementation of new technologies, particularly in low- and middle-income countries. To meet the demands of contemporary orthopaedic sports medicine, educational strategies must evolve through global collaboration, integration of emerging technologies, and commitment to equity. Standardised, multidisciplinary, and evidence-informed training models are needed to ensure optimal patient care and professional competence across diverse healthcare environments
