Making intubation and extubation safe in the Covid era
Get PDFThe highly infectious COVID-19 pandemic has in a way or the other affected everyone. Health care workers particularly anaesthesists who deal with airway manipulation are at an increased risk of being infected. Invasive procedures such as intubation and extubation performed mostly by anaesthetists are classified as procedures with high risk of aerosol generating particles where respiratory droplets containing the virus can easily spread to the surroundings. Various methods of preoxygenation, intubation and extubation have been further discussed and improvised with the aim of reducing the spread of aerosolization and making intubation safe. The purpose of this review is to identify the new techniques that are safe and effective in reducing aerosolization of respiratory droplets during the process of intubation and extubation. Anaesthetists are often not familiar with these new techniques and protocols. Thus far, no scientific data has been made available to support the superiority of each technique. Further research is needed to investigate each technique in the future
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Differences in Attitude towards End-Of-Life Care among Haemodialysis Patients and their Family Members in Two Malaysian Hospitals
Get PDFINTRODUCTION: End-of-life (EOL) care has become an important topic of discussion in those with chronic illness, especially in End Stage Renal Disease (ESRD) patients on dialysis. This study explored attitudes towards the EOL care among haemodialysis patients and compared them with the patients’ family members. MATERIALS AND METHODS: The study was a cross-sectional descriptive study conducted in two tertiary hospitals in Malaysia. The data was collected by using a survey questionnaire from 164 participants which consisted of 82 pairs of patients and their relatives. RESULTS: ‘Patient’ and ‘family’ groups demonstrated differences in their preferences regarding EOL care options. Family members group favoured cardiopulmonary resuscitation (81.7% vs 41.4%) (p <0.001), endotracheal intubation (80.5% vs 43.9%) (p = 0.989) and nasogastric tube feeding (87.8% vs 67%) (p = 0.001) more than patients themselves. The physician was the most nominated surrogate decision-maker by the patient (91.5%). Majority of the patients (57.3%) felt uncomfortable discussing EOL care options. There was significant correlation between duration of dialysis and patients’ EOL preferences where patients less than 5 years on haemodialysis favoured CPR (55.9% vs 31.3%; p = 0.026), intubation (55.9% vs 35.4%) and nasogastric tube feeding (82.3% vs 56.3%; p = 0.013) compared to patients who had been on haemodialysis for 5 years or longer. CONCLUSION: This study demonstrated significant differences between the attitudes of the patients and their relatives regarding EOL care preferences.
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
