Nitrofurantoin and Fosfomycin Susceptibility Among Outpatient Uropathogens in a Tertiary Care Center in Southern Thailand
No full textObjective: To document susceptibility to fosfomycin and nitrofurantoin among uropathogens isolated from the Out Patient Department and Emergency Room of Songklanagarind Hospital.Material and Methods: From October 2011 to May 2012, bacteria isolated from urine specimens of outpatients with pyuria were evaluated for susceptibility to nitrofurantoin and fosfomycin. The medical records of the patients were reviewed for uropathogens and other antimicrobial susceptibilities. The urinary tract infections (UTIs) were classified into complicated and uncomplicated. Factors associated with fosfomycin and nitrofurantoin susceptibilities were also studied.Results: The study included 324 patients with positive urine cultures. Complicated UTIs and uncomplicated UTIs were found in 72.8% and 27.2%, respectively. The most common causative uropathogen was Escherichia coli (E. coli) (71.9%) followed by Klebsiella pneumoniae (16.7%). The susceptibility of E. coli to fosfomycin was 98.7%, and the susceptibilities of E. coli, K. pneumoniae, and overall pathogens to nitrofurantoin were 91.0%, 24.1% and 74.1% respectively. Conclusion: The uropathogens in Songklanagarind Hospital have higher susceptibilities to fosfomycin than to nitrofurantoin.</jats:p
G-control Charts for Contamination Rates of Blood Cultures in a University Hospital
Get PDFObjective: To determine blood culture contamination rates, and display with a g-chart.
Materials and Methods: The medical records of patients, from whom blood cultures were obtained in a university hospital, during January and December 2019 were retrieved and reviewed for contamination. The Center for Disease Control and Prevention (CDC) criteria were used to classify the blood culture results. The contamination rates were illustrated with a g-chart.
Results: We identified 331 false-positive blood cultures, among 32,961 cultured specimens; yielding a contamination rate of 1.0% (95%CI = 0.9% – 1.1%). The highest contamination events occurred in the Emergency department (49.2%), Pediatric ICU (5.2%) and Neonatal ICU (4.8%), respectively. The most common commensal bacterial genus were Staphylococcus coagulase negative (67.1%), Bacillus spp. (10.2%) and Corynebacterium spp. (7.6%), correspondingly. The g-charts could identify 14 abnormal variations, in 41 locations.
Conclusion: The contamination rates found were within ranges of other reports. G-charts are simple to construct, easy to interpret and sensitive for detection of real time epidemics
Anxiety, Optimism, and COVID-19 Vaccine Hesitancy among Students in a University in Southern Thailand during the 2021 Academic Year
No full textThis study examined the prevalence of COVID-19 vaccine hesitancy and its associated factors, including anxiety and optimism, surrounding the COVID-19 pandemic among Thai university students. An online observational cross-sectional study was conducted between November and December 2021. Descriptive analyses and logistic regression were performed using R. In total, 409 university students participated in the study. Most reported high anxiety levels (69.4%), while more than half also expressed high levels of optimism associated with the COVID-19 pandemic (51.1%). Only 4.4% were unvaccinated, among whom 50% were hesitant to receive vaccination (2.2%). Per statistical analysis, those who perceived the available vaccines as low safety were significantly associated with a higher risk of vaccine hesitancy (p = 0.03). In contrast, those who reported that they would likely to receive the COVID-19 vaccine if recommended to by their doctors or pharmacists were significantly associated with lower vaccine hesitancy (p = 0.048). However, both anxiety and optimism regarding the COVID-19 pandemic were not associated with vaccine hesitancy. Thus, healthcare workers play an important role in COVID-19 vaccination counseling to prevent transmission. Health education during the pandemic should focus on COVID-19 infection as well as COVID-19 vaccines, including their safety and their adverse effects
Antimicrobial Resistance Patterns Amid Community-Acquired Uropathogens in Outpatient Settings of a Tertiary Care Hospital in Thailand
Get PDFObjective: To document the distribution of antimicrobial resistance patterns of community-acquired uropathogens.
Materials and Methods: Outpatient microbiology data of urine culture results in Songklanagarind Hospital between January to December 2019 were reviewed.
Results: This study included 649 episodes of positive urine cultures in 598 patients, in which 80.7% were symptomatic cases. The elderly (median 63 ± IQR 26 years) showed high prevalence of urinary tract infections in this study, for which nearly 80% of all samples were female. The three most common uropathogens identified were: Escherichia coli (E. coli) (69.6%), Klebsiella pneumoniae (9.5%) and Staphylococcus saprophyticus (4.9%). E. coli were highly resistant to ciprofloxacin (49.0 %), cotrimoxazole (41.2%) and ceftriaxone (20.6%), but had a low level of resistance to fosfomycin (0%), and amikacin (0.4%).
Conclusion: The antimicrobial resistance pattern of E. coli was high for commonly antimicrobial agents used in outpatients; especially quinolone, cotrimoxazole and cephalosporin. However, due to low resistance levels, fosfomycin and amikacin could be considered as effective treatment options for community acquired UTIs in our study

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
