Patterns of Medication Prescription among Children and Adolescents with Attention-Deficit/Hyperactivity Disorder in the United States
No full textThe objectives of this study are to: (1) quantify the difference in the annual number of prescription medications (total and unique) between children and adolescents with ADHD and those without ADHD; and (2) identify the most prescribed medication classes and unique medications among children and adolescents with ADHD. A retrospective cross-sectional study design was employed using data from the 2015 and 2017 Medical Expenditure Panel Survey. The study sample comprised children and adolescents (5–17 years). In the 5–12-year age group, those with ADHD were 2.4%, 17%, and 15% significantly more likely to have one, 2–4, and ≥5 prescription medications, respectively. Similarly, those in the 13–17-year age group were more likely to have one prescription medication (3%), 2–4 prescription medications (15%), and ≥5 prescription medications (12%) than those without ADHD. The most prescribed medications among children and adolescents with ADHD were methylphenidate and amphetamine-dextroamphetamine. ADHD was associated with both higher annual total and unique prescription medications. Additionally, concurrent use of prescription medications was more prevalent among children and adolescents with ADHD. High-quality randomized clinical trials on the safety and efficacy of combinations of multiple psychotherapeutics and stimulants’ agents are required to guide the evidence-based practices
Serious Psychological Distress and Emergency Room Use among Adults with Multimorbidity in the United States
Get PDFObjectives. (1) To examine the association between serious psychological distress (SPD) and emergency room (ER) use in the past 12 months among adults with multimorbidity in the United States (US) and (2) to investigate the association between SPD and the reasons for ER use. Methods. The current study used a cross-sectional design with retrospective data from the 2015 National Health Interview Survey. Logistic regression models were used to assess the association between SPD and ER use among adults with multimorbidity. Among ER users, adjusted logistic regression models were conducted to examine the association between SPD and the reasons for the ER use. Results. After controlling for other variables, adults with multimorbidity and SPD were more likely to use ER than those with multimorbidity and no SPD (AOR = 1.61, 95% CI = 1.26, 2.04). Among ER users, there were no significant associations between SPD and the reasons for ER use after controlling for other variables. Conclusion. Adults with multimorbidity and SPD were more likely to use ER as compared to those with multimorbidity and no SPD. Among adults with multimorbidity, routine screening for SPD may be needed to reduce the ER use.</jats:p
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
Preventive Medication Use among Adults Aged 40 and over in the United States: National Health and Nutrition Examination Survey, 2015–2018
No full textObjectives: 1. To estimate the prevalence of preventive medication use among adults in the United States (US); 2. To identify the socioeconomic, demographic and clinical factors associated with preventive prescription medication use; 3. To identify the diagnoses associated with preventive prescription medication use. Methods: Data from two cycles of the National Health and Nutrition Examination Survey, 2015–2016 and 2017–2018, are analyzed. Results: Among US adults aged 40 years or older (N = 7634), 31% use a preventive medication. Specifically, 27% of them use aspirin and 9% use other preventive prescription medications. Among those who use other preventive prescription medications, 27% report using one of the cardiovascular agents and 24% reported using anticoagulants and/or antiplatelet agents. High percentages of preventive prescription medication users report using medications to prevent heart attacks/myocardial infarctions (25%) or blood clots (23%). Uninsured adults are less likely to use preventive medications (OR: 0.656; p-value = 0.009) as compared with their counterparts with private insurance. On the other hand, older adults and those with diabetes, heart disease, arthritis and hypertension are more likely to use preventive medications. Furthermore, past smokers and adults who never smoked are more likely to use preventive medications as compared with those who currently smoke. Conclusion: Policies are needed to increase access to preventive care for uninsured adults. Further research needs to review the benefits and harms of the chronic use of preventive medication among older adults in the US
Self-reported receipt of preventive practices and its associated factors among adults with diabetes in the United States
No full textPrevious studies indicated that a high proportion of adults with diabetes do not receive recommended preventive care in the United States. Nevertheless, a comprehensive evaluation of the factors associated with the receipt of most recommended preventive care measures collectively is lacking. Therefore, this study describes the utilization of multiple preventive care measures collectively. Moreover, this paper aims to identify factors associated with receiving the recommended preventive care. A cross-sectional study design was implemented using data from multiple panels (2009–2015) of the Medical Expenditure Panel Survey. The sample included adults aged 21 years or older with diabetes (n = 8415). The outcome for this study was either receiving five selected preventive care measures (HbA1c tests, cholesterol tests, foot examinations, dilated eye examinations, and influenza vaccines) collectively or not. Multivariable logistic regressions were performed among all adults with diabetes, those with multimorbidity, chronic kidney disease (CKD) or eye complications. Adults with diabetes were poorly adherent to receiving the five preventive care measures collectively (15.6%). Among all adults with diabetes, factors associated with receiving all the selected preventive practices included age, education, health insurance, prescription drug coverage, duration of diabetes, number of chronic conditions and smoking status. Similar results were observed among adults with multimorbidity. Among adults with CKD, those with private insurance and drug prescription coverage were more likely to receive the recommended practices. The findings suggest low adherence to receiving all five recommended practices. It is crucial to increase the awareness about the need for all the recommended practices among adults with diabetes.

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
