Welcome to Seminars in Thrombosis & Hemostasis 2017 - New (2015) Impact Factor and Most Highly Cited Papers.

Welcome to thebeginning of yet another year with Seminars in Thrombosis & Hemostasis (STH). This is my 9th year as Editorin-Chief, and my 12th year of editorial association with this journal, having originally served as a regional editor. First, as always, I wish to sincerely thank all the contributors to STH over past years, as well as the guest editors for these past issues, and of course the current and past senior and associate editors of the journal. There have been no new changes to the editorial team.We remainwith four senior editors:Marcel Levi and Ton Lisman are European-based Senior Editors, and Hau Kwaan and Sam Schulman are North America–based Senior Editors. We also increased the ranks of associate editors last year, with the aim to have around 10 to 12 editors contributing from each of the “global regions” of America, Europe, and Asia Pacific. This set of editors will remain active in 2017. I will also take this opportunity to thank the journal production teamatThiemeMedical Publishers for theirhighproduction standards and for facilitating both the print and online issues of the journal. In particular, I would like to thank SubhankarDe, the project manager for STH, who manages the production process of STH issues and articles. I alsowish to thankother key people at Thieme, who prefer to remain unnamed, for additional support provided over the recent years. This is also the time that we reflect on our journal’s Impact Factor, which for 2015 was 3.505, which represents a small fall from our 2014 Impact Factor of 3.876 (►Fig. 1). I am hopeful that this reflects a stabilization of the STH Impact Factor at around 4 over coming years. I also assessed the trends for Impact Factor changes for 2015 versus 2014 for STH in comparison with other thrombosis and hemostasis-
