History and Pioneers of Cardiac Anesthesia in Italy
No full textThe first use of extracorporeal circulation in Italy occurred in 1951 in Turin. In the 1960s only 12 heart surgery centers were using extracorporeal circulation to treat patients, and health professionals had to complete their training abroad. During the last 50 years, Italian cardiac anesthesia has become a branch of major importance, and it has experienced a constantly growing number of active centers and professionals. Today, about 50,000 cardiac surgeries are performed every year in approximately 100 centers. Many results have been achieved during this period, thanks to the contribution of several pioneers. In this article, the history of Italian cardiac anesthesia and the role of Italian anesthesiologists in the development of this subspecialty in Italy and Europe are reviewed

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
