Il programma vaccinale antinfluenzale per la stagione 2025-26: una sintesi per il setting pediatrico
No full textThe seasonal influenza vaccination campaign is the larg
est and most complex public health intervention conduct
ed annually by the National Health Service, aimed to re
duce individual risk of illness, hospitalization and mortal
ity. It also seeks to minimize transmission risk to high-risk
groups, thereby decreasing social costs associated with
morbidity and mortality. The Ministry of Health releases
an annual circular outlining vaccine compositions based
on recommendations from the World Health Organization
(WHO). Notably, the upcoming 2025-2026 season will be
marked by a shift to trivalent vaccines, omitting the
B/Yamagata strain due to its absence since March 2020.
The inclusion of children aged 6 months to 6 years in
vaccination recommendations reflects a strategic public
health initiative to control influenza transmission. Effec
tive communication strategies are essential for improving
vaccination adherence across vulnerable populations
Papillomavirus vaccination: never again without it! The evolution of knowledge
No full textHuman papillomavirus is the most common sexually transmitted infection in the world. Most HPV infections resolve spontaneously within 2 years from infection; however, persistent infection may result in a wide array of diseases, ranging from genital warts to cancer. Most cases of cervical, anal and oropharyngeal cancers are due to HPV infection, with cervical cancer being one of the leading causes of cancer death in women worldwide. The development of HPV vaccine has shown a drastic decrease in HPV-related diseases. The vaccine, if administered before the start of sexual activity, prevents cervical cancer and shows effectiveness in over 90% of cases. Vaccination uptake remains low worldwide because of a limited knowledge of HPV. The use of a single-dose vaccine may facilitate the completion of prevention programmes for many children and adolescents as its efficacy and duration of protection is comparable to the two-dose schedule. Regular community sensitization and awareness campaigns by relevant authorities and implementers may help to increase the HPV vaccine uptake and decrease cancer and HPV-related morbidity and mortality worldwide
Vaccino anti-papillomavirus: uno per tutti, tutti per uno!
No full textA 17 anni dall’introduzione del vaccino contro il papillomavirus, sembra che ci sia una solida “immunità di gruppo” anche nella popolazione non vaccinata. La vaccinazione non solo protegge gli individui dall’infezione ma contribuisce anche alla prevenzione del cancro correlato per tutti. È fondamentale lavorare per aumentare le coperture vaccinali (ancora basse) per sfruttare appieno questo straordinario strumento di prevenzion
COVID 19 vaccine in the pediatric age: the recommendation of the Italian Pediatric Society
Full text linkVaccine is an important and effective tool to protect from preventable infectious diseases. Neverthless, in the COVID-19 pandemic era, scientific and accurate information are required to responde to false and misleading information on efficacy and safety of immunization in the pediatric age
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
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
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
