Dose-Escalation Trial of Mesenchymal Stromal Cells in Patients with Medical Xerostomia
The goal of this clinical trial is to evaluate the safety and tolerability of injecting certain cells produced in bone marrow called mesenchymal stromal cells (MSCs) into salivary glands. The main question it aims to answer is whether injection of MSCs into salivary glands results in any improvement in dry mouth. Participants will: - have bone marrow collected using a needle - undergo a salivary gland ultrasound - complete questionnaires - receive an injection of the bone marrow cells into a salivary gland

Double-blind Placebo Controlled Study to Evaluate the Effect of NAD+ Boosting With Nicotinamide Riboside on Immunometabolism and Immunity in Systemic Lupus Erythematosus
Study Description: Systemic lupus erythematosus (SLE) occurs predominantly in women and is driven by type I interferon dysregulation and neutrophil hyperresponsiveness. Neutrophils in females have reduced mitochondrial bioenergetic capacity which affects immunometabolism. Nicotinamide adenine dinucleotide (NAD)+ boosting with nicotinamide riboside blunts type 1 IFN activation in-vivo in monocytes of healthy subjects and ex-vivo in SLE subjects. These findings support the proposal of the hypothesis that NAD+ boosting by NR supplementation will modulate metabolic pathways in lupus and blunt type 1 interferon signaling. Moreover, as type 1 interferon drives endothelial dysfunction,...

Dronabinol After Arthroscopic Surgery
The purpose of the proposed study is to evaluate the efficacy of dronabinol for postoperative pain after arthroscopic surgery of the knee. The investigators hypothesize that dronabinol will relieve pain, reduce opioid consumption and will result in few negative side effects. If this pilot study shows promising results the investigators will expand the trial to include additional arthroscopic surgeries (hip, shoulder) and other types of orthopaedic surgery.

Dual Mobility Acetabular Cups in Revision TJA
The aim of this study is to the compare clinical outcomes of patients undergoing a revision total hip arthroplasty (THA) with the use of a dual mobility bearing versus a single bearing design with the use of a large femoral head (36mm or 40mm). We hypothesize the use of dual-mobility components in revision THA will be associated with a lower dislocation rate in the first year following surgery.

Dual Mobility in "High Risk" Patients
The aim of this study is to compare clinical outcomes of patients considered to be high risk for prosthetic dislocation undergoing primary total hip arthroplasty (THA) with the use of a dual mobility bearing versus a conventional, single bearing design.

Duke Lupus Registry
Lupus is a systemic autoimmune disease that can present with many varied symptoms, including joint pain, fevers, kidney disease, and rashes. Lupus can affect anyone, but it is most common in younger women. The Duke Lupus Registry will collect information and blood samples from patients with lupus (systemic lupus erythematosus or cutaneous lupus) seen in the Duke Rheumatology clinics. The goal of this Registry is to understand how lupus changes over time so that we can improve the treatment of patients with lupus.

Duke Spine Outcome Study (DSOS)
The primary goal of this registry is to increase the knowledge about spine tumors and other spine disorders to guide appropriate management strategies for the future. This registry will include the review of medical records, data collection for health related quality of life questionnaires, and collected tissues and samples. The study will require obtaining spinal lesions (tumor, etc.), blood, and bone marrow samples (from non-lesional bone) from selected patients, which will be collected during your surgery.

Duloxetine Metabolism and Fibromyalgia
People with fibromyalgia report generalized body pain ("pain all over"), increased sensitivity to painful stimulation, chronic tiredness or low energy, sleep problems, and other physical and functional problems. The exact cause of the disorder is poorly understood, and treatment can be difficult. The degree to which duloxetine is helpful for people with fibromyalgia varies greatly. For some people, it is very helpful for managing fibromyalgia symptoms. For others, people may not notice any benefit. Yet for some, it is a little helpful and the effect is noticeable only when people forget to take the medicine. The purpose of this study is to collect data to better understand the...

Dynamic Treatment Regiments for Glucocorticoid Tapering
The purpose of this clinical trial is to better understand how people with rheumatoid arthritis (RA) respond to gradual dose reduction, or "tapering", of steroid medications like prednisone. Some people with RA have symptoms when steroid dose is reduced, while others don't. This trial will look at different patient characteristics, including levels of inflammation in the body, differences in the way the brain processes sensory information, and certain hormone levels, to help researchers better understand why different people have these different responses to steroid tapering. The hypotheses include: - Greater or equal to ( ) 30% of participants in each arm will develop...
