Prevalence and antibiotic sensitivity profiles of Staphylococcus aureus nasal carriage among preclinical and clinical medical students in a Malaysian university
No full textAims: Prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) strains in healthcare (HA-MRSA) and
community (CA-MRSA) incurred costly morbidity and mortality. This study assessed the prevalence and antibiotic
sensitivity profile of S. aureus and MRSA isolates from medical students.
Methodology and results: A cross-sectional study of nasal swabs from 60 medical students yielded 93% positive S.
aureus. In this study, erythromycin, fusidic acid, gentamicin, penicillin, vancomycin and methicillin were used. The most
significant antibiotic sensitivity against S. aureus was fusidic acid (p-value = 0.0042). The S. aureus and MRSA isolates
from clinical students were more resistant than those of preclinical students against erythromycin (44%15%), fusidic
acid (33.3%10%), penicillin (85%86.9%), vancomycin (11.1%-) and methicillin (19.4%15%) respectively while the
isolates from preclinical students were more resistant than those of clinical students against gentamicin (5%-).
Conclusion, significance and impact of study: In this study, gender, age and duration of clinical exposure had no
significant bearing on the prevalence of nasal S. aureus and MRSA respectively. No MRSA infections were detected in
preclinical (15%) and clinical (19%) students positive for MRSA, suggesting that these students may be carriers of CAMRSA.
A larger study will be implemented to provide baseline data for monitoring CA-MRSA infections, genotyping and
constructing of phylogenetic tree
Laboratory Biorisk Management Manual : Faculty of Medicine and Health Science, 6th October 2016
Get PDFThe Faculty of Medicine and Health Sciences, Universiti Malaysia Sarawak is proud to
launch its own Biorisk Management Manual. The development of this manual was part of project (GTRX-14-60789-0) to Dr. Tan Cheng Siang under the Biosecurity Malaysia Enhancement Grant (BMEG) from the Biosecurity Engagement Program (BEP) US Department of State which was executed via CRDF Global.
The Biorisk Management Manual was carefully written by the Faculty’s Biorisk Management Manual Committee and was based on the internationally recognized CWA15793 document. The manual provides a management system for both biosafety and biosecurity aspect and hope to help the Faculty of Medicine and Health Sciences to spearhead biorisk management in UNIMAS and beyond.
I believe the launching of our Faculty’s Biorisk Management Manual in timely with the global development in biosafety and biosecurity
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
