Handgrip Strength in Lung Transplant Candidates and Recipients
No full textObjectives: Handgrip strength is increasingly used to assess muscle strength in various conditions. In this review, we investigated handgrip strength in patients receiving or awaiting lung transplant.Materials and Methods: For this integrative review, we searched 8 databases from inception through February 2023. Two keyword entries, '' handgrip strength '' and '' lung transplantation,'' were matched using the Boolean operator, AND. No filters were applied for document type, age, sex, publication date, language, and subject.Results and Conclusions: The searched databases returned 73 citations. Nine articles considering 487 patients (49% female) were included in the final analysis; 7 studies were observational, and 2 were randomized controlled trials. In 7 of 9 studies, handgrip strength was measured with a hydraulic dynamometer. In candidates for lung transplant, handgrip strength ranged from 27.1 kg (before rehabilitation) to 31.2 kg (after rehabilitation). In lung transplant recipients, handgrip strength ranged from 21.1 kg (before rehabilitation) to 35.7 kg (after rehabilitation). Handgrip strength in lung transplant candidates with chronic obstructive pulmonary disease was higher (89 +/- 18% predicted) versus patients with interstitial lung disease (79 +/- 18% predicted). Improvements in maximal inspiratory pressure and maximal expiratory pressure were observed in those patients whose handgrip strength improved after rehabilitation. Nonsarcopenic patients walked longer distances for the 6-minute walking test (> 450 m) versus sarcopenic patients ( 20 kg) versus sarcopenic patients (< 20 kg). Handgrip strength testing should be implemented both in preoperative and postoperative contexts to evaluate physical potential of patients and drive rehabilitative activities toward the most impaired domains
Does Preoperative Rehabilitation Influence the Quality of Life in Patients Who Are Candidates for Lung Transplant?
Full text linkObjectives: Lung transplant is an excellent therapeutic option for patients with advanced/end-stage pulmonary disease. The purpose of this review was to define whether preoperative rehabilitation influences quality of life in patients who are candidates for lung transplant.Materials and Methods: This was a scoping review conducted by searching 4 primary databases from inception until January 2022. Three keywords, "lung transplantation," "preoperative rehabilitation," and "quality of life," were matched using the Boolean operator AND. In each database, the following fields were searched: PubMed (all fields), Scopus (title, abstract, keywords), Cochrane Library (title, abstract, keywords), and Web of Science (topic). Filters were applied for age (adult only) and language (English only). No filters were applied for gender, publication date, and subject. The search process was completed in January 2022.Results and Conclusions: We retrieved 57 citations from these databases. After removal of duplicates, 41 documents were screened for eligibility. Two articles were included in the final analysis: 1 was a systematic review, and 1 was an observational prospective study. The rehabilitative interventions were mainly focused on motor and breathing exercises and were integrated by education programs. Preoperative rehabilitation was effective at improving quality of life and mood status and reducing dyspnea in patients waiting for lung transplant. In addition, the 6-minute walking distance increased after patients participated in preoperative rehabilitation. Preoperative rehabilitation was composed of different types of exercise with variable duration (3-20 weeks) and frequency (3-6 times per week). Patients on the active wait list for lung transplant should be encouraged to attend preoperative rehabilitation in order to preserve and improve their quality of life

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
