Do more targets allow more cancer treatments, or not?
No full textThe three current oncology models (histological, agnostic and mutational) mainly differ in clinical, technological and organisational aspects, leading to different regulatory procedures and implications in antineoplastic therapy access by patients. Within the histo-logical and agnostic models, Regulatory Agencies authorise target therapies and define their price, reimbursement, prescription and access based on results from clinical trials including patients affected by the same tumour (histological) or subjects with specific genetic mutations regardless of the tumour site or the histology (agnostic). The mutational model has been developed to identify specific actionable molecular alterations found by next-generation se-quencing test-based large platforms on solid and liquid biopsies. Nevertheless, due to the highly uncertain efficacy and possible toxicity of drugs tested within this model, regulatory procedures based on histological or agnostic oncology cannot be followed. Multidisciplinary skills are required (e.g. the molecular tumour board's (MTB) representatives) to identify the best association between the genomic profile and the drug planned to be used, but quality requirements, practices and procedures of these discussions still need to be standardised. Real -world evidence from clinical practice (i.e. genomic findings, clinical data and MTBs' choices) lacks, therefore, it is urgently needed as opposed to limited findings from clinical trials. A potential solution for an appropriate access to the therapy chosen by the mutational model can be the indication-value-based sub iudice procedure of authorisation. The access to therapies suggested by extensive molecular profiling could be easily implementable within the Italian national health system, thanks to the existing regulatory procedures, i.e. the managed- entry agreements and the antineoplastic drug monitoring registries, alongside those granted by conventional studies (phase I, II, III, IV) conducted according to the histological and agnostic models.(c) 2023 The Authors.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Real-world data on new users of atypical antipsychotics: characterisation, prescription patterns, healthcare costs and early cardio-metabolic occurrences from a large Italian database
No full textPurpose: To describe new users of atypical antipsychotics (APs) in terms of sociodemographic characteristics, cardio-metabolic risk profile, prescription patterns, healthcare costs and cardio-metabolic events over the 24 months after treatment initiation. Methods: Atypical AP new users were selected from the ReS database and grouped into three: patients already affected by cardio-metabolic diseases (group A), patients without these clinical conditions but with predisposing conditions (group B) and patients without cardio-metabolic diseases and predisposing conditions (group C). Annual prescription patterns and healthcare costs were analysed. Subjects of groups B and C were matched with controls to compare the occurrences of cardio-metabolic events over 24 months. Results: Thirty-two thousand thirty-four new users of atypical APs were selected (median age 69). The 22.3% had cardio-metabolic diseases, 14.8% had predisposing conditions and 62.9% had none of these. The 99.3% received monotherapy. The mean annual cost per patient was €2785, and the median cost was €1108. After 24 months, a cardio-metabolic event occurred in 11.5% of group B vs. 8.7% of the controls (p < .01), and in 5.0% of group C vs. 2.1% of the controls (p < .01). Conclusion: Patients treated with atypical AP were on average old and, in a non-negligible amount, with cardio-metabolic disease or predisposing conditions. New users of atypical APs showed a significantly higher likelihood to develop a cardio-metabolic event early after treatment initiation.

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Price and reimbursement for orphan medicines and managed entry agreements: does Italy need a framework?
Full text linkThis article illustrates a consensus opinion of an expert panel on the need and usefulness of a framework for price and reimbursement (P&R) process and managed entry agreements (MEAs) for orphan medicines in Italy.
This opinion was gathered in three rounds: an introductory document was sent to the panel and discussed during a recorded online meeting. A second document was sent to the panel for their review. In the third step the final document was validated. Members of the expert panel are the authors of the article.
The panel agreed that Italy does not need a specific value framework for orphan medicines, driving the P&R process. Rather, a more structured value framework for all medicines tailored to the specific drugs can be useful. For orphan drugs, the panel advocated for a multidisciplinary approach and the contribution of different stakeholders to value assessment, and acknowledged the importance of addressing, more than for other drugs, unmet needs, equity issues and societal value. The panel raised the need of increasing the importance of patient-reported outcomes. Experts, acknowledging the growing criticisms in implementation of outcome-based agreements in Italy, expressed their position against their abandonment in favour of discounts only and supported orphan medicines as natural candidates for these agreements.
Finally, the panel made some recommendations on the appraisal process for orphan medicines, including an early discussion on the uncertainty of the evidence generated and the adoption of a structured approach to identify the agreement, which better responds to the uncertainty
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
