HTRS and ISTH Announce Strengthened Collaboration

New official journal affiliation with RPTH

HTRS and the International Society on Throm

bosis and Haemostasis (ISTH) are excited to announce a new formalized collaboration to further the missions of both organizations. While our two leading medical research societies have worked together for decades, this strengthened partnership launches several concrete initiatives to further advance care for people with hemostatic and thrombotic disorders.

Specifically, an official journal affiliation is newly minted between HTRS and ISTH’s Gold Open Access journal, Research and Practice in Thrombosis and Haemostasis (RPTH), featuring these details:

  • RPTH will be listed by HTRS as its leading journal affiliation; however, HTRS will retain its two current journal affiliations with Thrombosis Research and Haemophilia
  • RPTH will publish up to four Mentored Review Articles annually, authored by HTRS-member early career investigator/trainees and their mentors; these articles will undergo peer review, and if accepted will be published as “HTRS Mentored Review Articles”
  • RPTH will publish up to four articles annually, authored by recipients of HTRS research award programs; these articles will also undergo normal peer review, and if accepted, they will be published as “HTRS Research Award Articles”

As a key feature in this new alignment, RPTH will publish abstracts accepted to the HTRS biennial Scientific Symposium, beginning with the HTRS 2021 Scientific Symposium recently completed this March.  Starting in 2023, RPTH will publish Illustrated Abstracts prior to the Scientific Symposium, highlighting the contributions of invited speakers. Additional collaboration throughout the year surrounds joint marketing and communications opportunities.

Rare Bleeding Disorders Elevated on the National Health Agenda 

New Commitment from National Hemophilia Program Coordinating Center and Treatment Centers

Hemophilia has been named recently as one of only two rare bleeding disorders in Healthy People 2030 (HP2030), identified as a pressing public health issue alongside conditions such as cancer, diabetes, and heart disease.  Released by the U.S. Department of Health and Human Services in August 2020, HP2030 is a focused list of national objectives that aims to track and improve the health and well-being of society over the next decade.

One of these priorities, BDBS-01, will strive to reduce the proportion of people with severe hemophilia who have more than four joint bleeds per year.  Inclusion of BDBS-01 is significant for the hemophilia community. 

"Inclusion of bleeding disorders as a priority on the national health agenda is an important achievement and has resulted from a coordinated, dedicated advocacy by our community," said HTRS Member Amy Shapiro, MD, CEO and co-medical director at the Indiana Hemophilia & Thrombosis Center, Inc., a member HTC within the Great Lakes Regional Hemophilia Network.  "Together with our federal partners and treatment centers across the country, we are committed to achieving this goal."

Data on BDBS-01 is gathered at more than 140 HTCs in the U.S. through the Community Counts: CDC Public Health Surveillance Project for Bleeding Disorders on individuals of all severity of disease.  HTC diligence has assisted in elevating these chronic conditions to a level of national public health awareness.

National Institutes of Health Center for Scientific Review

The Center for Scientific Review (CSR) at the National Institutes of Health (NIH) offers two programs that could be valuable for HTRS members:


Early career scientists who would like review experience can apply to participate in the NIH Early Career Reviewer (ECR) Program. The goals of the ECR Program are to help early career scientists become more competitive as grant applicants through first-hand experience with peer review and to enrich and diversify CSR's pool of trained reviewers.

For more info or to apply to the ECR Program, please CLICK HERE


HTRS members are invited to recommend scientists to serve as grant reviewers through the NIH Review Recommendation portal. Reviewers should be scientists who are generally willing to serve as reviewers and are seen as experts, with integrity, in their field. They should have an active research program, extramural funding, and not currently be a standing member of an NIH study section or advisory council. The NIH is encouraging HTRS to recommend productive scientists from diverse backgrounds and career stages – e.g. assistant, associate, and full professors.

If you would like HTRS to nominate you or a colleague as an NIH reviewer, please email [email protected] for more info.
