Recurrent syncopal events preceded by transient abnormal gait disturbance.
No full textA previously fit and well patient in his 70s presented after recurrent transient loss of consciousness following dinner with alcohol consumption. Each event has been preceded by several minutes of transient abnormal posture and gait. More specifically, there were several minutes of stiffening of legs, shuffling gait and gait ataxia. Initial clinic investigations, including ECG, echocardiogram, CT and MRI head scans, vestibular tests and biochemistry for vitamins and electrolytes, proved inconclusive. However, a positive tilt table test demonstrated severe orthostatic hypotension (OH) with loss of consciousness.Acute alcohol consumption worsens OH, and prolonged hypotension can potentiate cerebral hypoperfusion leading to syncopal events. Compromise to posterior circulation during these events may cause transient gait abnormalities. Such cases have not been widely documented in the literature. Transient gait disturbance in syncope remains underexplored. Further research and documentation are needed, informing better diagnostic and management strategies
Assessing deprescribing tools for implementation in care homes: A qualitative study of the views of care home staff.
Full text linkBackground: Care home residents often experience polypharmacy (defined as taking five or more regular medicines). Therefore, we need to ensure that residents only take the medications that are appropriate or provide value (also known as medicines optimisation). To achieve this, deprescribing, or the reduction or stopping of prescription medicines that may no longer be providing benefit, can help manage polypharmacy and improve outcomes. Various tools, guides, and approaches have been developed to help support health professionals to deprescribe in regular practice. Little evaluation of these tools has been conducted and no work has been done in the care home setting.
Objective: This qualitative study aimed to assess distinct types of deprescribing tools for acceptability, feasibility, and suitability for the care home setting.
Methods: Cognitive (think-aloud) interviews with care home staff in England were conducted (from December 2021 to June 2022) to assess five different deprescribing tools. The tools included a general deprescribing guidance, a generic (non-drug specific) deprescribing framework, a drug-specific deprescribing guideline/guide, a tool for identifying potentially inappropriate medications, and an electronic clinical decision support tool. Participants were recruited via their participation in another deprescribing study. The Consolidated Framework for Implementation Research informed the data collection and analysis.
Results: Eight care home staff from 7 different care homes were interviewed. The five deprescribing tools were reviewed and assessed as not acceptable, feasible, or suitable for the care home setting. All would require significant modifications for use in the care home setting (e.g., language, design, and its function or use with different stakeholders).
Conclusions: As none of the tools were deemed acceptable, feasible, and suitable, future work is warranted to develop and tailor deprescribing tools for the care home setting, considering its specific context and users. Deprescribing implemented safely and successfully in care homes can benefit residents and the wider health economy.

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
