Identification of a Potential Novel Role for Factor IX Using a Zebrafish Model
EMS Provider Education Regarding Bleeding Disorders and the Treatment Required in an Emergency
People with bleeding disorders are often connected to and with various community members such as local and national foundations/associations, their home health company, nurses , pharmaceutical representatives, etc. While people are often encouraged to wear medic alert ID, they do not know anyone in the EMS system who may be caring for them in case of an emergency. Through this project, EMS providers will receive education regarding bleeding disorders and the treatment required in an emergency. This project will seek to connect the HTC's with the EMS systems locally and regionally to coordinate the education with the EMS professionals to provide care.
Analysis of Lower Extremity Joint Characteristics, Biomechanics, and Neuromotor Control during Gait in Patients with Hemophilia
Hemophilia causes repetitive bleeding episodes throughout the musculoskeletal system, primarily into joints, such as knees and ankles. This leads to significant joint damage resulting in increased pain reproduction, decreased functional abilities, such as walking, and negatively impacts quality of life. Traditionally the extend of joint damage has been examined via clinical assessments, such as the Hemophilia Joint Health Scores, x-rays, MRIs, and more recently musculoskeletal ultrasound (MSKUS). However, these modalities fail to establish the global impact of joint damage on the entire body of a person with hemophilia and their functional abilities. Analyzing joint motion and forces acting upon the joint during walking has been a widely established technique to gain understanding of abnormal three-dimensional movements and is a key factor in clinical decision making-processes. With the overall goal of establishing better treatment approaches for persons with hemophilia it is vital to understand the underlying functional joint limitations. Therefore, the purpose of this study is to investigate characteristics of damaged joints, joint motion and control as well as forces acting upon the joint during walking in persons with hemophilia.
Understanding of a Neurophenotype in Hemophilia A
The Prevalence of Depression and Anxiety in Children with Coagulopathies Being Treated at a Hemophilia and Thrombosis Center
The hemophilia and thrombosis centers in Tucson and Phoenix would like to join efforts to make a meaningful contribution to our understanding of the mental health profile of our pediatric population. This knowledge could contribute to a more tailored approach when designing clinics and programming, and, by identifying mental health issues, inform the development of targeted interventions. We hope to look at the prevalence of depression and anxiety in children with bleeding disorders including hemophilia, von Willebrand disease, and other congenital coagulopathies. We expect that the existence of a chronic health condition could affect a child's psychological development. We're also aware of the critical impact of family culture so our survey will include data on the mental health of the participants’ primary caretakers as well as other significant socioeconomic markers.

Quality of Life and Outcome Improvement in Adolescents with Bleeding Disorders Receiving Medical Management for Heavy Menstrual Bleeding
Women with Hemophilia: Gender-based Differences in the Delivery of Comprehensive Care
This study will evaluate hemophilia treatment center (HTC) services provided to women with hemophilia A or B (Factor VIII or Factor IX level [ 50%). The American Thrombosis and Hemostasis Network (ATHN) maintains a confidential national database for patients with bleeding and clotting disorders. Utilizing this existing ATHNdataset, the study will analyze the effect of gender on the delivery of comprehensive care in patients with hemophilia A and B. The project will focus on how gender impacts three specific components of care: identification of patients with factor VIII or IX deficiency, inclusion of patients in the comprehensive care model, and monitoring of joint bleeding as a key component of comprehensive care provided by HTCs. Demonstrating gender-based disparities in comprehensive care would provide evidence for making changes to improve the clinical care provided to women with hemophilia. This study will add to the knowledge regarding the care of women with hemophilia, helping to inform future studies of this under-researched population.

Investigation of VWF as an Immunomodulator of the Immunogenic Response Towards FVIII
Dr. Shi is a Professor of Pediatric Hematology at the Medical College of Wisconsin and an Investigator of Blood Research Institute at the BloodCenter of Wisconsin. She earned her MD from Fujian Medical University in China in 1990 and her Ph.D. in 1998. Dr. Shi’s research focus is to formulate innovative therapeutic approaches for the treatment of hemophilia A, a genetic bleeding disorder caused by a lack of the critical blood clotting protein, factor VIII (FVIII). One of her research programs funded by the National Institutes of Health, National Heart, Lung, and Blood Institute, is to develop platelet-specific gene transfer strategies for the treatment of hemophilia A and hemophilia A with neutralizing antibodies. In the project supported by the NHF Bridge Grant, Dr. Shi will investigate the potential effect of the FVIII carrier protein, von Willebrand factor, on FVIII immune responses in hemophilia A. Dr. Shi expects that results from her studies will aid the design of more effective protocols to prevent FVIII immune responses and to induce FVIII immune tolerance in patients with HA.
