The VISA-A (sedentary) should be used for sedentary patients with Achilles tendinopathy: a modified version of the VISA-A developed and evaluated in accordance with the COSMIN checklist.

OBJECTIVE: To develop and evaluate a modified version of the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire, for use in sedentary patients with Achilles tendinopathy, using the Consensus-based Standards for the selection of health Measurement Instruments recommendations. METHODS: Twenty-two sedentary patients with Achilles tendinopathy completed the VISA-A and provided feedback regarding the relevance, comprehensiveness and comprehensibility of each item, response options and instructions. Patient and professional feedback was used to develop the VISA-A (sedentary) questionnaire. Reliability, validity and responsiveness of the VISA-A (sedentary) was evaluated in 51 sedentary patients with Achilles tendinopathy: 47.1% women, mean age 64.8 (SD 11.24). RESULTS: Factor analysis identified two dimensions (symptoms and activity) for the VISA-A (sedentary). Test-retest reliability was excellent for symptoms (intraclass correlation coefficient, ICC=0.991) and activity (ICC=0.999). Repeatability was 1.647 for symptoms and 0.549 for activity. There was a significant difference between the VISA-A and VISA-A (sedentary) scores both pretreatment and post-treatment. There was stronger correlation between the pretreatment to post-treatment change in the VISA-A (sedentary) scores (r=0.420 for symptoms, r=0.407 for activity) and the global rating of change than the VISA-A scores (r=0.253 for symptoms, r=0.186 for activity). CONCLUSION: The VISA-A (sedentary) demonstrates adequate reliability, validity and responsiveness in sedentary patients with Achilles tendinopathy. The VISA-A (sedentary) is a more appropriate measure than the VISA-A for this cohort and is recommended for clinical and research purposes.

Multi-Coil MRI Reconstruction Challenge-Assessing Brain MRI Reconstruction Models and Their Generalizability to Varying Coil Configurations.

Deep-learning-based brain magnetic resonance imaging (MRI) reconstruction methods have the potential to accelerate the MRI acquisition process. Nevertheless, the scientific community lacks appropriate benchmarks to assess the MRI reconstruction quality of high-resolution brain images, and evaluate how these proposed algorithms will behave in the presence of small, but expected data distribution shifts. The multi-coil MRI (MC-MRI) reconstruction challenge provides a benchmark that aims at addressing these issues, using a large dataset of high-resolution, three-dimensional, T1-weighted MRI scans. The challenge has two primary goals: (1) to compare different MRI reconstruction models on this dataset and (2) to assess the generalizability of these models to data acquired with a different number of receiver coils. In this paper, we describe the challenge experimental design and summarize the results of a set of baseline and state-of-the-art brain MRI reconstruction models. We provide relevant comparative information on the current MRI reconstruction state-of-the-art and highlight the challenges of obtaining generalizable models that are required prior to broader clinical adoption. The MC-MRI benchmark data, evaluation code, and current challenge leaderboard are publicly available. They provide an objective performance assessment for future developments in the field of brain MRI reconstruction.

Applying interpretive phenomenological analysis to library and information science research on blended librarianship: A case study.

Although interpretive phenomenological analysis (IPA) has value in library and information science (LIS), it has low uptake in Africa. The methodological and theoretical approaches to using IPA in LIS and other disciplines are outlined, including a critical analysis of applying double hermeneutics and horizontalization to construct a hermeneutic interpretation. A blended librarianship thesis conducted in Zimbabwe is compared with LIS-based IPA studies and blended librarianship research to reflect the value of IPA methods. The illustration narrates how IPA was implemented within the context of phenomenology to analyse the complexity of academic librarians' views, taking into consideration social and historical environments. The weaknesses of the study are discussed, including the use of quality criteria of credibility, dependability, and transferability. The guided analysis of the study encourages the use of IPA in LIS as it can solve research problems and generate new theories to inform practice, services, philosophy, theory, and institutions.

Health researchers and policy makers involvement in knowledge translation activities in Malawi.

PURPOSE: The purpose of this paper is to explore health researchers' involvement of policy or decision makers in knowledge translation activities in Malawi. DESIGN/METHODOLOGY/APPROACH: The case study collected quantitative through questionnaire from health researchers from the University of Malawi. The study used inferential statistics for the analysis of the quantitative data. Pearson χ2 test was used to establish the relationship between categorical data and determine whether any observed difference between the data sets arose by chance. The Kruskal-Wallis H test was used to determine if there were statistically significant differences between independent variable and dependent variables. Data has been presented in a form of tables showing means, standard deviation and p-values. FINDINGS: Health researchers sometimes involve policy or decision makers in government-sponsored meetings (M=2.5, SD=1.17). They rarely involve policy or decision makers in expert committee or group meetings (M=2.4, SD=1.20). Researchers rarely involve policy or decision makers in conferences and workshops (M=2.4, SD=1.31). Rarely do researchers involve policy or decision makers in formal private or public networks (M=2.4, SD=1.17). In events organised by the colleges researchers rarely involve policy or decision makers (M=2.3, SD=1.11); and rarely share weblinks with policy or decision makers (M=2.0, SD=1,17). On average, health researchers occasionally conduct deliberate dialogues with key health policy makers and other stakeholders (M=2.5, SD=1.12). The researchers rarely established and maintained long-term partnerships policy or decision makers (M=2.2, SD=1.20). They rarely involve policy or decision makers in the overall direction of the health research conducted by themselves or the Colleges (M=2.1, SD=1.24). RESEARCH LIMITATIONS/IMPLICATIONS: The study recommends that there should be deliberate efforts by health researchers and policy makers to formally engage each other. Individuals need technical skills, knowledge of the processes and structures for engaging with health research evidence to inform policy and decision making. At the institutional level, the use of research evidence should be embedded within support research engagement structures and linked persons. PRACTICAL IMPLICATIONS: Formal interactions in a form of expert meetings and technical working groups between researchers and policy makers can facilitate the use of health research evidence in policy formulation. SOCIAL IMPLICATIONS: In terms of framework there is need to put in place formal interaction frameworks between health researchers and policy makers within the knowledge translation and exchange. ORIGINALITY/VALUE: There is dearth of literature on the levels of involvement and interaction between health researchers and health policy or decision makers in health policy, systems and services research in Malawi. This study seeks to bridge the gap with empirical evidence.

Levels of research evidence in health policy assessment in Malawi.

PURPOSE: The purpose of this study is to examine levels of health research evidence in health policies in Malawi. DESIGN/METHODOLOGY/APPROACH: The study selected a typology of health policies in Malawi from 2002 to 2017. The study adopted the SPIRIT conceptual framework and assessed the levels of research evidence in health policy, systems and services research using the revised SAGE policy assessment tool. Documentary analysis was used to assess levels of health research evidence in health policies in Malawi. FINDINGS: In 29 (96.7 per cent) of the health policies, policy formulators including healthcare directors and managers used generic search engines such as Google or Google Scholar to look for heath research evidence. In 28 (93.3 per cent) of the health policies, they searched for grey literature and other government documents. In only 6 (20 per cent) of the heath policy documents, they used academic literature in a form of journal articles and randomised controlled trials. No systematic reviews or policy briefs were consulted. Overall, in 23 (76.7 per cent) of the health policy documents, health research evidence played a minimal role and had very little influence on the policy documents or decision-making. RESEARCH LIMITATIONS/IMPLICATIONS: The empirical evidence in the health policy documents are limited because of insufficient research citation, low retrievability of health research evidence in the policy documents and biased selectivity of what constitutes health research evidence. PRACTICAL IMPLICATIONS: The study indicates that unfiltered information (data from policy evaluations and registries) constitutes majority of the research evidence in health policies both in health policy, systems and services research. The study seeks to advocate for the use of filtered information (peer reviewed, clinical trials and data from systematic reviews) in formulating health policies. ORIGINALITY/VALUE: There is dearth of literature on the levels of health research evidence in health policy-making both in health policy, systems and services research. This study seeks to bridge the gap with empirical evidence from a developing country perspective.
