Assessment of adverse drug reactions caused by HAART at antiretroviral clinics in the Maseru district, Lesotho
Get PDFMPham (Pharmacy Practice), North-West University, Potchefstroom Campus, 2014Antiretroviral drugs are successful in controlling HIV/AIDS and reducing disease progression. Antiretroviral regimens are stopped in up to 25% of all patients during their initial treatment therapy as a result of adverse drug effects, failing treatment and nonadherence within the initial eight months of treatment (Sharma et al., 2007: 235). A pharmacovigilance surveillance system makes it possible for physicians, pharmacists and other healthcare providers to report suspected ADRs. The purpose of this system is to operate as a guide in identification of new ADRs and predisposing risk factors to known ADRs. The objective of this study was to assess the prevalence and documentation of adverse drug reactions (ADR) in the private and public antiretroviral clinics in Maseru district, with special reference to zidovudine (AZT) and tenofovir (TDF) - based regimens. The empirical investigation was divided into two phases. The first phase was a cross-sectional quantitative retrospective drug utilisation review study which focused on the occurrence of adverse drug reactions in patients taking zidovudine (AZT) and tenofovir (TDF). The second phase, a survey in a form of questionnaires for the health professionals. Drug utilisation review: The sample size of patients was 300. Of the 44 patients who experience ADRs, 72.73% (n = 32) were female and 27.27% (n = 12) were male. A greater number of patients who experienced ADRs were females with 43.18% (n = 19) presenting with skin rash, 27.27% (n = 12) with nausea/vomiting, and 2.27% (n = 1) with diarrhoea. In male patients, 2.27% (n = 1) had peripheral neuropathy, 18.18% (n = 8) skin rash, 2.27% (n = 1) Fanconi syndrome, 2.27% (n = 1) nausea/vomiting, and 2.27% (n = 1) diarrhoea. Patients whose ART regimen changed due to ADRs were five. 60% (n = 3) of the patients were females and 40% (n = 2) were males. There was an estimated increase of 0.0025 cell/mm³, 0.0026 cell/mm³, 0.0024 cell/mm³, 0.0025 cell/mm³, and of 0.0019 cell/mm³ in CD4 cell count per day according to sex, age group, weight group, initial ART regimen, and ADRs, respectively. An estimated increase of 0.00021 g/dL, 0.00022 g/dL, 0.00018 g/dL, 0.00022 g/dL, and of 0.00020 g/dL in Hb profile per day occurred according to sex, age group, weight group, initial ART regimen, and ADRs, respectively. There was an estimated increase of 0.000062%, 0.000046%, 0.000068%, 0.000062%, and of 0.00017% in neutrophil count according to sex, age group, weight group, initial ART regimen, and ADRs per day, respectively. There was an estimated increase of 0.000044 IU/L, 0.000043 IU/L, 0.000046 IU/L, and of 0.000028 IU/L in ALT according to sex, age group, weight group, and initial ART regimen per day, respectively. An estimated decrease of 0.000013 IU/L in ALT according to ADRs per day also occurred. There was an estimated decrease of 0.00038 μmol/L, 0.00039 μmol/L, 0.00040 μmol/L, 0.00040 μmol/L, and of 0.00028 μmol/L in serum creatinine per day according to sex, age group, weight group, initial ART regimen, and ADRs, respectively. There was an estimated decline of 0.00023 mmol/L, 0.00022 mmol/L, 0.00023 mmol/L, 0.00024 mmol/L, and of 0.00015 mmol/L per day in urea according to sex, age group, weight group, initial ART regimen, and ADRs, respectively. Health professional’s questionnaire: 49 health professionals responded to the questionnaire. 100% (n= 49) of the participants showed that they did not use the yellow card scheme to report ADRs. 34.65% (n = 17) use the individual case safety reports. 57.14% (n = 28) used the structured databases to report ADRs. 85.71% (n = 42) documented in the patient bukana, and 6.12% (n = 3) used the HIV/AIDS ART card to document ADRs occurrence. 91.84% (n = 45) of the health professionals never filled the ADR reporting form in their working environment. In conclusion, adverse drug reactions occurring in a hospital or healthcare facility should be recorded and reported by the medical practitioners, nurses, pharmacists, and the pharmacy technicians. Therefore, it is important to assess the continuous evaluation of the benefits and harm of medicines which will help in achieving the ultimate goal of making safer and more effective treatment available for patients. As well as to help the health professionals to participate in the very important process of continuous surveillance of safety and efficacy of pharmaceutical products used in clinical practice.Master
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
