Management of Autoimmune Hemolytic Anemia in the Midst of Coronavirus Disease 2019 Pandemic: A Case Report
Get PDFIntroduction : The novel coronavirus disease 2019 (COVID-19) has become a pandemic involving all people and can be severe and life-threatening in a certain population such as those with comorbidity. Autoimmune hemolytic anemia (AIHA) is an autoimmune hematologic disease characterized with antibodies production that binds to red cell surface antigens. In this pandemic, several concerns have been raised by autoimmune disease clinicians and patients regarding the use of immunosuppressive drugs. In this case report, we illustrate the problems of autoimmune hemolytic anemia patient when she got active case.Case Illustration : A 28 years old lady was admitted to the hospital owing to fatigue and tiredness during exercise for two weeks. She had been diagnosed with autoimmune hemolytic anemia before and did not comply with the treatment. This patient has been reevaluated of having AIHA from the symptoms of fatigue, enlarged spleen, low hemoglobin, increased reticulocytes, signs of hemolytic in blood smear examination, increased indirect bilirubin, LDH and the Combs’ test result was given positive. She received methylprednisolone 2 mg/kg of body weight intravenously, washed packed red cells (PRC), calcium and proton pump inhibitor. She was discharged at the seventh day since admission and she was prescribed oral methylprednisolone equal to 1 mg/kg body weight.Conclusion : This is an educated case of non-compliance of AIHA that should be given high dose steroid and blood transfusion during hospitalization amid the COVID-19 pandemic. The recommendation of treatment for AIHA was still the same as before the pandemic occured
A Systematic Review of Coronavirus Disease 2019 with Respiratory Distress Syndrome in Adult: Focus on Risk Factors, Mechanism, Diagnosis, and Treatment
Get PDFContext: Coronavirus disease 2019 (COVID-19) is a newly discovered disease, caused by SARS-CoV-2 and currently has become a pandemic. Acute respiratory distress syndrome (ARDS) is the most common complication in COVID-19. There were numerous conflicting results among articles related to it. The aim of this study is to ascertain the most compelling evidence about ARDS in COVID-19.Evidence Acquisition: This systematic review was registered in PROSPERO (CRD42020180379). A systematic search was conducted in PubMed, PubMed central, and Google Scholar on April 16, 2020. Two reviewers independently searched and selected the articles. The risk of bias was evaluated using the Newcastle-Ottawa Quality assessment tool.Results: A total of 1,647 articles were screened, 9 articles were included. Patients were classified as having various degrees of ARDS, the diagnosis of COVID-19 was confirmed by PCR nasopharyngeal swab. Risk factors of ARDS in COVID-19 reported were older age, male gender, and pre-existing medical conditions. Cytokine storm was thought to play a role in the mechanism of ARDS. The main treatment for COVID-19 was supportive and symptomatic. To date, there is no antiviral treatment recommended for COVID-19 and the given treatment for ARDS in COVID-19 was similar to other pneumonia-induced ARDS. No additional therapy specific for ARDS in COVID-19 has been proposed.Conclusion: Our synthesis of the literature showed that there was no good evidence in the mechanism and treatment of ARDS. Further translation research in the mechanism of ARDS and continuing with clinical trials evaluating drug efficacy for ARDS in COVID-19 is needed
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
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
