Risk factors for prescription drug diversion among people living with HIV: a systematic scoping review
In addition to numerous infections and frequent pain constantly affecting people living with HIV (PLWH), various risk factors might contribute to prescription drug diversion. The purpose of the study is to map existing evidence on risk factors contributing to prescription drug diversion among PLWH. Arksey and O'Malley's framework and the recommendation by Levac et al. (2010) guided this study. We searched for relevant literature from the following databases: PubMed; Google Scholar; EBSCOhost (Academic Search Complete, MEDLINE and Newspaper Source), Cochrane, WHO, HIV, ScienceDirect and Open Access Theses and Dissertations. Studies reporting evidence on risk factors contributing to prescription drug diversion and published in the period January 1996 to July 2017 were included. Thematic content analysis was performed to summarize the findings. The search identified 734 studies. After full-text screening of the eligible studies, risk factors contributing to prescription drug diversion among PLWH were reported in 20 included studies. It was found that there is limited research on prescription drug diversion among PLWH in low-middle-income countries (LMICs). Risk factors contributing to prescription drug diversion were being a substance user or substance dependent; being male; young in age; being stigmatized; not disclosed HIV status; diagnosed with mental health problems; being HIV infected; poor health and well being; being White; being homeless or not owing a home; having low educational level; having history of diversion, misuse or abuse; in possession of addictive prescriptions; being unemployed and living in high neighbourhood disorder. Evidence shows that there is limited research on prescription drug diversion among PLWH in LMICs. The study findings show that the risk factors contributing to prescription drug diversion are related with risk factors for HIV transmission and infection.
Evidence of factors influencing self-medication with antibiotics in low and middle-income countries: a systematic scoping review
Self-medication with antibiotics (SMA) is a practice of global concern with a higher incidence within the low- and middle-income countries (LMICs). Despite worldwide efforts to control and promote the rational use of antibiotics, the continuing practice of SMA systematically exposes individuals and communities to the risk of antibiotic resistance and a host of other antibiotic side-effects. This systematic scoping review maps evidence on the factors influencing SMA in these settings. The search strategy involved electronic databases including PubMed, Web of science, Science Direct, EBSCOhost, Google Scholar, BioMed Central, and the World Health Organization Library. PRISMA P guidelines and Arksey and O'Malley's framework were used. Thematic analysis was used to identify the factors that influence the practices of SMA in LMICs. The Mixed Method Appraisal Tool (MMAT), version 2011, was used to assess the quality of the included primary studies. Fifteen studies met the inclusion criteria. Studies included participants from the following LMICs: Guatemala, India, Indonesia, Kenya, Laos, Nepal, Nigeria, Pakistan, Sri Lanka, and Yemen. The findings of the review emphasized a considerable high prevalence of SMA, ranging from 8.1% to 93%, with an association with the level of education, monthly income, and gender of participants. Accessibility, affordability, and conditions of health facilities, as well as the health-seeking behavior, are factors that influence SMA in LMICs. Health conditions such as a sore throat, common cold, cough, headache, toothache, flu-like symptoms, pain relief, fever, runny nose, toothache, upper respiratory tract infections, and urinary tract infection were the major complaints that led to the practices of SMA. There is a considerable level of research evidence predominantly in some LMICs from Asia, with less evidence from African LMICs. Sociocultural determinants of health associated with the structure and conditions of health system as well as the health- seeking behavior are the main factors influencing SMA. Contextual and comprehensive studies on the factors influencing the non-prescribed use of antibiotics are needed to enable evidence-based strategies to correctly address the utilization of antibiotics and contain the problem of antimicrobial resistance, especially within the LMICs.
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
