Vasculitis Pregnancy Registry
The purpose of this study is to learn about the experience of women with vasculitis who become pregnant. In particular, the study will consist of several online surveys to assess 1. each woman's vasculitis severity and pregnancy-related experiences, and 2. pregnancy outcomes.

VCRC Tissue Repository
The purpose of this study is to collect existing tissue specimens from subjects enrolled in Vasculitis Clinical Research Consortium (VCRC) studies. Analysis of these tissue specimens and linked clinical data collected through VCRC studies may lead to the identification and development of a series of translational research projects. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular...

Vestibulodynia: Understanding Pathophysiology and Determining Appropriate Treatments
Vestibulodynia (VBD) is a complex chronic vulvar pain condition that impairs the psychological, physical, and sexual health of 1 in 6 reproductive aged women in the United States. Here, the investigators plan to conduct a randomized, double-blinded, placebo-controlled clinical trial to 1) compare the efficacy of peripheral (lidocaine/estradiol cream), centrally-targeted (nortriptyline), and combined treatments in alleviating pain and improving patient-reported outcomes and 2) determine cytokine and microRNA biomarkers that predict treatment response in women with distinct VBD subtypes. Positive findings from this study will readily...

Veteran Ear Acupuncture Pilot Project
Veterans who have responded well to Battlefield Acupuncture (BFA), a form of auricular acupuncture, in routine clinical practice will be invited to receive education to insert the needles themselves at home. A 3D-printed wearable prosthetic will also be explored as a means to facilitate needle placement. Primary end-points will include whether adverse events occur over a six-month period and whether the aforementioned prosthesis significantly facilitates needle placement in terms of subjective ease of administration.

ViviGen Cellular Bone Matrix for Hindfoot or Ankle Arthrodesis
To evaluate the fusion status of the hindfoot bones after receiving the ViviGen graft, an FDA approved cellular bone matrix. This is used in a population indicated for hindfoot arthrodesis as an alternative to an autograft.

Walking Gait Biomechanics Following Knee Joint Effusion
The purpose of this study is to determine the sensitivity of a wearable sensor to detect changes in knee joint loading using an experimental knee joint effusion as a model for a common clinical physiological alteration in joint status. The rationale for this project is that it will establish the efficacy of an inexpensive, clinically, and publicly available device that can detect changes in biomechanical loading due to acute physiologic change in joint status. The study will utilize a cross-sectional cohort study design and will seek to enroll 25 male and female healthy adult participants (18-35 yo). Participants will report to the...
