A Study of the Experimental Neuro-Spinal Scaffold™ Device for Complete Thoracic AIS A Spinal Cord Injury

Volunteer for research at UC Davis and contribute to discoveries that may improve health care for you, your family, and your community!

The purpose of this study is to test the safety and benefit of a new medical device. This device is implanted into the injured spinal cord for a recent spinal cord injury. The procedure to implant the medical device may be added to the usual, standard treatment for spinal cord injury. The study doctor will attempt to perform your surgery as soon as possible. The medical device is experimental and is not approved by the FDA. There is no evidence that the medical device will be of any benefit to you. However, the study will look at whether the new medical device helps improve the medical condition of patients with recent spinal cord injuries.

A Study of the Effectiveness and Safety of Oxiplex® Gel to Reduce Pain and Symptoms Following Lumbar Disc Surgery

Please consider joining this clinical research study if you are having surgery for a herniated lumbar disc.

This study will examine the safety and effectiveness of an experimental device called Oxiplex. Oxiplex gel is not yet approved in the U.S. by the FDA. Oxiplex may help prevent some of the side effects that can occur after lower back spine surgery. This includes leg pain not resolved with surgery, back pain, and neurological symptoms such as weakness and numbness. Oxiplex gel is a sterile, bioresorbable (dissolves and absorbs into the body) product. The gel does not require removal after surgery and clears from the body. Oxiplex may improve post-surgical leg and back pain by providing a physical barrier for the nerves around your surgical site. It is applied during the lumbar spine surgery to coat the sensory nerves. This barrier isolates the nerves from tissues and fluid that may cause inflammation in that area.

BOOST3 is a research study to learn if either of two strategies for monitoring and treating patients with TBI in the intensive care unit (ICU) is more likely to help them get better. Both of these alternative strategies are used in standard care. It is unknown if one is more effective than the other. In one strategy doctors concentrate only on preventing high ICP (intracranial pressure) caused by a swollen brain. In the other strategy doctors try to prevent high ICP, and also try to prevent low PbtO2 (brain oxygen). It is unknown if measuring and treating low brain oxygen is more effective, less effective, or the same as monitoring and treating high brain pressure alone. The results of this study will help doctors discover if one of these methods is more safe and effective.

Are you experiencing sciatica (leg pain), from a herniated disc?

Please consider joining this clinical research study examining the effectiveness of an investigational drug injection for leg pain.

The goal of this clinical trial is to test if a single injection in the spinal disc works well. The investigational injection will be tested in patients with lumbar disc herniation (LDH). Lumbar disc herniation (LDH) is very common and happens when the soft center of a spinal disc bulges out. This bulging can compress nearby nerves causing pain, numbness, or weakness in a leg. This study is conducted at the UC Davis Spine Center. You will receive all study medication, or control injection and study evaluations at no cost, and compensation for your time is available.

Clinical Trial of Experimental LimiFlex for Treating Degenerative Spondylolisthesis With Spinal Stenosis (narrowing of the spine)

UC Davis is participating in the Control Arm for this study. Website: https://limiflextrial.com/

Degenerative spondylolisthesis is when one of the bones in your spine has moved forward in relation to the vertebra below it. Degenerative spondylolisthesis can cause or worsen lumbar spinal stenosis. This is a narrowing of one or more areas in the lower part of your spine. This narrowing can put pressure on the spinal cord or spinal nerves and cause pain, numbness or weakness in your legs, back, or buttocks. To treat your condition, your doctor is recommending spinal surgery. Before patients are enrolled into this study, doctor offices will be considered a Control Site or an Investigative Site. All patients will be offered posterior decompression surgery to help relieve abnormal pressure on nerves that are causing the pain and discomfort. This standard of care surgery is also called laminectomy. During the decompression surgery, your doctor will remove the bone in your spine that is causing your pain. The purpose of the decompression surgery is to help relieve abnormal pressure on your nerves that is causing pain and discomfort. Dr. Kim and University of California Davis Health will be considered a Control Site. After the decompression, patients at the Control Sites will have a procedure called spinal fusion. This surgery is also called a transforaminal lumbar interbody fusion (TLIF) with posterolateral fusion (PLF) or a posterior decompression surgery with spinal fusion. In the spinal fusion procedure, bone is placed around the vertebrae to cause the vertebra to connect so that they behave and move as one block. This is called a posterior (done from the back) lumbar fusion and is done to help stabilize the spine.

Low Frequency Deep Brain Stimulation of cognitive performance in Parkinson's Disease

Research evaluating memory and thinking ability

The purpose of this research is to determine whether deep brain stimulation can improve memory and thinking ability in people with Parkinson’s disease. People with Parkinson’s disease have difficulties with movements, tremor, and balance. However, people also have difficulty with thinking, planning, and remembering. Eventually many people with Parkinson’s disease develop dementia. Currently there are few treatments available for difficulties with thinking. We believe that low frequency electrical deep brain stimulation may improve thinking in people with Parkinson’s disease. We hope that this research will help us develop new treatments for people with cognitive difficulties in Parkinson’s disease, and slow the progression to dementia.

The role of the subthalamic nucleus (SBN) in perceptual decision-making in humans

Help us understand how electrical signals in the brain translate to the making of decisions

The purpose of this research is to help us understand how the brain makes decisions. Several mental diseases, such as disorders of addiction, are due to problems with the way people make decisions. These diseases are very common. When these mental diseases are severe, sometimes medications are no longer effective. In these difficult cases, Deep Brain Stimulation (DBS) surgery may be an option. However, until we understand how the electrical signals in the brain translate to the making of decisions, we cannot design surgeries to treat these patients. Therefore, this study will help us understand the specific ways the brain makes certain types of decisions. We hope that this research will help us develop new treatments for people with mental diseases
