Cost-Effectiveness of Escalating to Natalizumab or Switching Among Immunomodulators In Relapsing-Remitting Multiple Sclerosis In Italy
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
Using 2nd generation basal insulins in type 2 diabetes: Costs and savings in a comparative economic analysis in Italy, based on the BRIGHT study
Background and aims: To evaluate the economic impact of using 2nd generation basal insulin analogs, Glargine 300 Units/ml (Gla-300) vs Degludec 100 Units/ml (IDeg-100), in patients with type 2 diabetes (T2D). Methods and results: An economic analysis was conducted using findings from the BRIGHT study (the first controlled, head-to-head study comparing Gla-300 vs IDeg-100), and costs for the Italian National Healthcare Service (NHS). A cost-minimization analysis (CMA) and a budget impact analysis (BIA) were conducted. Only pharmacological costs were included in the analysis. The CMA estimated patient treatment costs at 24 weeks and 1 year; the BIA assessed the economic impact of treating the overall Italian population of T2D insulin-naïve patients, who initiated insulin treatment during the period September 2017–August 2018 (N = 55 318). In the BIA, four different scenarios were compared: i) all patients receive IDeg-100 (Scenario A); ii) 61% of patients receive Gla-300, 39% IDeg-100 (Scenario B); iii) 80% of patients receive Gla-300, 20% IDeg-100 (Scenario C); iv) all patients treated with Gla-300 (Scenario D). The average treatment costs per patient were lower with Gla-300 vs IDeg-100 (at 24 weeks: €129 vs €161; at 1 year: €324 vs €409, respectively). Results of the BIA showed that comparing Scenario D vs Scenario A, total savings would amount to €1.76 million at 24 weeks, €4.73 million at 1 year, €5.53 million at 2 years. Conclusion: A larger use of Gla-300 vs IDeg-100 for the treatment of T2D patients would lead to a relevant reduction of therapy costs in Italy

Ventana ALK (D5F3) in the Detection of Patients Affected by Anaplastic Lymphoma Kinase-positive Non–Small-cell Lung Cancer: Clinical and Budget Effect
Patients with anaplastic lymphoma kinase-positive (ALK + ) advanced non–small-cell lung cancer should benefit from targeted therapy. The effect of increased use of an immunohistochemical technique was estimated using a health care–economics analysis. Extensive use of D5F3 has resulted in a diagnostic costs decrease. These savings could be reinvested to test a greater number of patients (53% vs. 75%). Reinvesting the saving would lead to an overall survival gain (+20%). Background: To ensure identification of anaplastic lymphoma kinase-positive (ALK + ) patients, the Italian Drug Agency suggested a testing algorithm based on the use of fluorescence in situ hybridization (FISH) and/or immunohistochemistry. The aim was to evaluate the clinical and economic effects of adopting an immunohistochemical test (Ventana ALK D5F3) as an option for detecting ALK protein expression in advanced non–small cell lung cancer (NSCLC) patients. Materials and Methods: A budget impact model was developed by adopting the Italian National Health Service (NHS) perspective and a 5-year period to compare 2 scenarios: the current use of D5F3 (28%; current scenario) and increased use of D5F3 (60%; alternative scenario). The testing cost and the number and cost of the identified ALK + patients were evaluated. Results: A more extensive use of D5F3 in the alternative scenario showed a decrease in diagnostic costs of ∼€468,000 compared with current scenario when considering all advanced NSCLC patients. If these savings were allocated to test more NSCLC patients (75% vs. 53%), an incremental cost per identified ALK + patient of €63 would be required, leading to an overall survival gain for the alternative scenario compared with the current scenario (32.4 vs. 27.1 months; relative increase, 20%). Conclusion: The use of D5F3 would provide a cost savings for the NHS owing to a lower acquisition cost than FISH and a comparable detection rate. The savings could be reinvested to test a greater number of patients, leading to more efficient identification, use of targeted therapy, and improvement in clinical outcomes of ALK + patients
Sertraline treatment for depression associated with acute coronary syndromes: a cost analysis from the viewpoint of the Italian Healthcare System
Background and aims: Depressive disorders (DD) are independent risk factors for rehospitalization after acute coronary syndromes (ACS) and, hence, for increased healthcare costs. A placebo-controlled safety trial of 24 weeks of treatment with sertraline after ACS (Sertraline Anti-Depressant Heart Attack Randomized Trial, SADHART) suggested that active treatment was associated with reduced rehospitalization due to coronary and non-coronary events. With the SADHART database, a cost analysis was carried out to determine the economic consequences of treating DD after ACS in the perspective of the Italian Healthcare System. Methods: Clinical information on medical events and rehospitalizations recorded over the study period was drawn from the original SADHART database, which did not contain information necessary for estimating indirect costs. Analysis was therefore limited to direct medical costs due to rehospitalizations, emergency room visits and hospital procedures, and the average Italian Diagnosis-Related Group (DRG) tariffs were applied. Results: With the exclusion of the cost of sertraline treatment, the average direct cost per patient over the study period was 3,418 8,290 E in the active treatment group and 4,409 9,439 E in the placebo group (p=0.3). After including the cost of 24 weeks of sertraline treatment, the average cost in sertraline-treated patients was only modestly increased, to 3,524 8,290 E. Conclusions: Treatment of major DD in patients with recent ACS can improve patient care without additional costs, and possibly with some savings, to the healthcare system
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
