Sean Quinn, PhD

Dr. Sean Quinn is a postdoctoral fellow at the Children’s Hospital of Philadelphia in the laboratory of Dr. Rodney Camire. Dr. Quinn received his doctoral degree in Biochemistry/Biophysics from Rensselaer Polytechnic Institute in 2019. For his JGP project, Dr. Quinn will develop novel monoclonal antibodies (mAbs) that bind and protect FV or activated FV (FVa) to promote coagulation in the context of hemophilia. To accomplish this goal, Dr. Quinn will use biochemical and biophysical approaches to map the epitopes where lead candidate mAbs bind to FV/FVa. Moreover, he plans to assess the efficacy of these mAbs using a combination of in vivo approaches with an already established hemophilia mouse model. Long-term, Dr. Quinn’s goal is to become an independent investigator to develop approaches to modulate anticoagulant pathways to treat bleeding.

Dr. Olubusola Oluwole

Since my first year of medical school, I have been actively involved in sickle cell disease (SCD) research with a focus on cognitive outcomes of patients affected by the disease. During my first year of medical school, I collaborated with my mentors, Dr. Enrico Novelli, and Dr. Noll and conducted an independent study that assessed cognitive impairment in children with SCD in Nigeria for which I served as a PI. I spent a month in Nigeria performing WISC IV cognitive assessments on children with SCD as well as a control group without the disease. The goal of the research was to elucidate the prevalence and correlates of CI in Nigeria. The experience laid a foundation for future longitudinal or interventional studies to ameliorate the disease burden of SCD in sub-Saharan Africa. It also furthered interest in the disease process of SCD especially in a neurological aspect of the disease course. During medical school, I was accepted into the Clinical Scientist Training Program where I conducted research exploring the relationship between arterial stiffness and cognitive functioning of individuals with SCD. Through this program, I was able to receive a Master of Science degree in clinical research. My most recent project deals with exploring the impact of hydroxyurea on cognitive functioning of children with SCD in Ghana. During my fellowship, I will continue to build on my prior training and research experiences. I am fortunate to be working with Dr. Kleber Fertrin and Dr. Rebecca Kruse-Jarres who both have an extensive career in management of patients with sickle cell disease. The proposed project will help me gain deeper understanding of neurocognitive outcomes and perhaps the prevention of neurocognitive outcomes in sickle cells disease. The Jean Marie Lusher Diversity Research Fellowship award will provide me with the support to achieve my goal of a prolific career in clinical and translational research in historically marginalized SCD patients.

Xuejie Chen

Dr. Xuejie Chen is a postdoctoral fellow in the laboratory of Dr. Darrel Stafford at the University of North Carolina at Chapel Hill. Before joining Dr. Stafford’s lab, she received her Ph.D. degree in Cell Biology from Beijing Normal University, P. R. China. In her JGP Fellowship project, Dr. Chen aims to study the contributions of extravascular factor IX (FIX) to blood coagulation and to search for FIX variants that could efficiently displace the endogenous dysfunctional FIX in hemophilia B patients. To achieve this goal, Dr. Chen will study the binding between FIX and the subendothelial basement membranes, mainly type IV collagen, and use the site-directed random mutagenesis library to screen for tighter binding FIX molecules. In doing so, she hopes to identify a FIX variant that can be used in hemophilia B patients for better coagulation therapies.

Kathaleen Schnur
A survey link will be distributed to all hemophilia treatment center social workers with the ask that they forward on to the various staff members at their center. Social workers and other staff will have separate surveys. The questions will be built to be asked in a cascading manner, one question at a time, with the goal of better understanding perceptions of the social work role . Additionally, the social worker will be asked to provide some demographic information to build from prior surveys within the literature. The data collected will be used to create a standards of practice of the social work role and ultimately improve patient care and interdisciplinary collaboration. The standards of practice is intended to capture all the things a social worker is capable of doing within the center. The intent is that this tool will be adaptable based on center size, setting, and layout.

Analysis of Lower Extremity Joint Characteristics, Biomechanics, and Neuromotor Control during Gait in Patients with Hemophilia

Year: 2019

Physical Therapy Excellence Fellowship
Author(s):
Lena Volland

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.
