CBD for Knee Osteoarthritis
Osteoarthritis is a disease that affects millions of Americans and is the leading cause of persistent pain and physical disability in the older adult population. Many physically active Americans have reported pain-relieving effects of cannabidiol (CBD) that can reduce or eliminate use of nonsteroidal anti-inflammatory drugs (NSAIDs) for activity-related pain with minimal to no side effects. Long-term use of over-the-counter medications, including NSAIDs, can pose a significant health risk, and therefore clinical research on the safety and efficacy of CBD is needed.

CD19-Directed Chimeric Antigen Receptor Autologous T Cells (CART19) for Lupus
This is a single-center, single-arm, open-label phase 1/2 study of CART19 in children and young adults with refractory Systemic lupus erythematosus (SLE), including both patients diagnosed with lupus nephritis (LN) and patients with non-renal Systemic lupus erythematosus (SLE). Phase 1 will evaluate the safety of CART19 in 6-12 patients with Systemic lupus erythematosus (SLE). There is no planned dose escalation, but a dose de-escalation will be made based on the incidence of Dose Limiting Toxicities. Phase 2 will evaluate the efficacy and further evaluate the safety of CART19 in this population.

CD40L Antagonism in Rheumatoid Arthritis (RA)
The primary objective is to determine if the addition of a 12-week course of treatment with VIB4920 to TNFi treatment will result in improved clinical disease control in patients with RA who have had an inadequate response to a TNFi.

Ceftriaxone Pulse Dose for Post-Treatment Lyme Disease
The goal of this clinical trial is to learn if an FDA approved drug, Ceftriaxone, given intermittently, can treat people between 18 and 75 years old with a history of Lyme disease, who are still experiencing persistent or returning symptoms after they have completed treatment. The main questions it aims to answer are: - Will giving Ceftriaxone approximately every 5 days for 6 weeks be safe and well tolerated when compared to a group that receives placebo (a look-alike substance that contains no drug)? - Will giving Ceftriaxone improve symptoms? Participants will be asked to do the following: - Come to the clinic approximately every 5-6 days to receive...

CEM-Plate and CEM-Cage First-In-Human Use Efficacy Study
The study is a prospective, first-in-human, multi-center, non-randomized, single-arm study to assess the safety and efficacy of the CEM-Cage used with the CEM-Plate in patients who are appropriate candidates for a 2-level anterior cervical discectomy and fusion (ACDF). Fifty patients will be enrolled in the study and, after undergoing a 2-level ACDF, will be evaluated at 4 weeks, 3 months, 6 months, 12 months, 18 months, and 24 months.

Cervical Paraspinal Muscle Twitching and Cervical Facet Radiofrequency Ablation Outcomes
The investigators aim to determine whether cervical paravertebral muscle twitching during motor testing as part of performing cervical RFAs is associated with a greater likelihood of treatment success, and greater magnitude or duration of analgesia. The investigators propose a straightforward grading scale based on visual and tactile information readily available during RFA procedures as part of routine practice (per radiofrequency electrode: 0 = no twitches palpated or observed; 1 = twitches palpated but not observed; 2 = twitches palpated and observed at 1-2 levels; 3= twitches palpated and observed at >2 levels). If a higher weighted score (total score divided by number of...

Characteristics and Disease Progression of Mixed Connective Tissue Disease and Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) are long-term autoimmune diseases in which the immune system attacks parts of the body. The abnormal immune reaction causes inflammation of and damage to various body parts and can affect joints, skin, kidneys, heart, lungs, blood vessels, and the brain. SLE and MCTD often affect young women, especially black and Hispanic women, and there is no known cure. Knowing more about SLE and MCTD will help in developing new and effective treatments. The purpose of this study is to characterize immune system abnormalities, genetic components, and disease progression in people with SLE and MCTD.

Characterization of Diseases With Salivary Gland Involvement
Background: - Salivary glands in and around the mouth and throat make saliva. Salivary gland disorders can affect a person s quality of life. Studying people who have a disease that affects their salivary gland(s) may teach researchers about the disorders and their genetics. Objectives: - To study salivary gland diseases and disorders. To collect data and samples from people with salivary gland problems and their relatives. Eligibility: - People more than 4 years old who have or are suspected to have a disease involving salivary glands. - Their relatives more than 4 years old. - Healthy volunteers 18 years or...
