Frequency, factors and pattern of delayed presentation for dialysis in advanced kidney disease patients visiting tertiary care hospital
Get PDFBackground: Globally the burden of chronic kidney diseases is increasing. It is often a silent disease until the most advanced stages when symptoms develop. Late referral and presentation to nephrologist for CKD management is the major issue.
Objective: To determine the frequency, factors and pattern of delayed presentation for dialysis in advanced kidney disease patients visiting tertiary care hospital.
Methods: The current cross-sectional study was conducted in Memon Medical Institute Hospital and Dow University of Health Sciences Ojha Campus Karachi Pakistan from December 2019 to March 2020. Patients who presented in hospital for first time dialysis with advanced kidney diseases were included in the study. The threshold of patient presentation after a month of advice for dialysis is used to categorize the patient presentation as delayed or non-delayed.
Results: Total 214 participants were recruited into the study. The median age of the participants was 40 (29.75 - 53) years. Majority were male (71%) and belonged to rural area (63.1%). 50.9% of the patients presented with delay of more than a month. Delayed presentation was significant among belonging to rural area (p=0.009) with higher median creatinine (p=0.002) and lower level of education (p=0.001). The most frequent presentation was high blood pressure (89.3%), followed by oliguria (66.8%). Oliguria was significant among patients with delayed presentation (p=0.003). Patient perception for delayed presentation was looking for transplant (69.2%) and fear of needle prick (52.3%).
Conclusion: Delayed presentation for dialysis is more common in male, from rural areas, with lower level of education and with symptoms like oliguria and fluid overload. Looking for renal transplant followed by the fear of needle emerged as the potential reasons of delayed presentation

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
Effect of Prone Positioning in Patients with Moderate COVID-19 Pneumonia Admitted to Ward at a Tertiary Care Hospital
Get PDFCOVID -19 pneumonia can progress to severe disease in 5% of patients requiring intensive care management, which can put an excessive burden on health care systems. Prone positioning has been shown to improve oxygenation and decrease lung injury in patients with COVID-19 pneumonia and can be used as an adjunctive treatment to delay intubation. The objective of this study is to assess the effect of prone positioning in patients admitted to the COVID ward, with Moderate COVID-19 Pneumonia. This experimental study was conducted at Liaquat National Hospital. A quasi-experimental study design was applied. Patients with hypoxemia SpO2 < 94% were assisted to prone and semi-prone for up to 2 hours at a time for multiple sessions. Parameters like SaO2, PaO2/FiO2, hours of proning and changes and X-rays were recorded daily and pre and post-intervention values were compared. Paired t-test and Wilcoxon sign test were used to compare continuous parameters. A two-tailed p-value less than 5% of the level of significance was defined as statistically significant. 20 patients fulfilling the inclusion criteria were enrolled. Median hours of prone positioning were 48.5. The median hospital stay was 7.5 days. At baseline, mean PaO2/FiO2 ratio was 342±91.87 and at the time of discharge, it was 412.30±105.97 which is a statistically significant improvement from baseline (p=0.040). 50% of patients showed improvement in X-rays. One patient was intubated and all the patients were discharged. The sample collected in the current showed that prone positioning is a safe and feasible approach to improve oxygenation in moderate-severe COVID-19 pneumonias. However, studies with a larger sample size are recommended to further verify the findings of this study
