UC Davis Health Clinical Studies

Fiber Study

The purpose of this study is to determine if dietary fiber increases overall gut health

The purpose of this study is to investigate whether consuming a packet of fiber powder per day changes the composition and/or function of the gut microbiota and high density lipoproteins (HDL) or good cholesterol. If you take part in this research, you will be responsible to keep your normal diet with low fiber content, defined as less than approximately 15g/day, or equivalent to approximately 4 servings of fruit, vegetable, legume, or whole grain combined per day. You also need to attend all the visits until the endpoint of the study and provide all the questionnaires and biological samples as instructed under your consent.

Dietary Intervention Clinical Trial
Any, age 18-45

Help us design better tools to manage continuous IV immunotherapy in acute lymphoblastic leukemia. Participate in a research study

We aim to understand the experiences of patients, caregivers, and nurses with continuous IV immunotherapy

The goal of this study is to learn about the experiences of patients, caregivers, and nurses with continuous IV immunotherapy. We want to understand the needs and challenges in managing continuous IV immunotherapy and how information about this therapy was provided to the patients, caregivers, and nurses. We aim to improve how we educate and support patients, family members, and nurses with this therapy in the future. We hope that the insights from this study will help us develop digital health or other tools.

A Study of Stratification and Algorithm in Opioid Use in Shoulder Arthroplasty Patients

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

We aim to better understand opioid use in patients having elective shoulder surgery. We plan to use a teaching session and pain contract to decrease opioid use after surgery. We hope to create a method for physicians to efficiently manage pain after surgery without causing opioid dependency. Elective shoulder surgery is on the rise, along with increased use of TSA in elderly patients. The need for determining optimal management without overprescribing narcotics has become very important. Decreased opioid use would mean decreased chance of having unwanted side effects of too much opioids. This inlcudes: - respiratory depression - nausea - sedation - driving restrictions - use by unintended individuals

A Study of Applying Prechtl's Assessment of General Movements for Preterm Infants Through Telemedicine

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

Preterm babies are more likely to have developmental challenges. Your baby qualifies for developmental screening to identify any concerns. Your doctor may refer you and your baby for early intervention developmental therapy. The first developmental screening visit is between 6 and 9 months corrected gestational age. Prechtl’s assessment of general movements (GMA) is a method of observing and characterizing babies' movements. If a baby has abnormal patterns of movement they are at higher risk for developmental delay. This may help in identifying infants that would benefit from early intervention services sooner. Traditionally, GMA assessment is done by creating video recordings of babies moving at different ages. Experts review those recordings separately from a clinic visit. The goal of our research study is to see if it is possible to do general movements assessment via telemedicine. We will study whether watching the baby move during a telemedicine visit has the same conclusion as watching the same video as a recording. If this assessment can be done via telemedicine, it may be able to be completed faster, on more babies, especially those that live far away.

An Observational Study of Patients Undergoing Therapy for Chronic Hepatitis B (HBV) Infection

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

This study will learn more about people with hepatitis B. By doing this study, researchers hope to: • Find out more about patients that have hepatitis B, including their age, race/ethnicity, and other medical conditions they may have • Learn about different medications, procedures, and other treatments that are being used to manage hepatitis B. • Understand changes that may be happening in the liver or throughout the body by looking at reports such as those for scans, tests, and biopsies

Become involved and join the fight against Alzheimer's disease in the African-American community

The goal of this study is to shed light on the clinical, cognitive, neuroimaging and biochemical markers of Alzheimer’s disease among older adults in the African-American community. One of the main reasons Alzheimer’s disease (AD) is known as the silent epidemic in the African-American community is because few African Americans have historically participated in Alzheimer's research. As a result, little is known about why the illness affects blacks twice as often as whites. Currently there is limited information about strategies to improve diagnosis and expand treatment options for older African American adults. The UC Davis Alzheimer's Disease Center, located in the East Bay, is creating the science that will uncover new ways of diagnosing the disease earlier and shape the development of more culturally-informed, effective treatments. The UC Davis Alzheimer’s Disease Center East Bay is a unique research and medical training facility focused on understanding how cognitive problems eventually develop into Alzheimer’s disease. We are one of the world’s cutting-edge research facilities and our team strives to create safe and effective treatments nationally and for our diverse Northern California population.

In-Home Autism Study

Are you a parent of a child with Autism?

Researchers at the UC Davis MIND Institute are collaborating with the Hartwell Foundation, Stanford University and Case Western University to reach thousands of families who are managing the challenges of caring for a child with an Autism Spectrum Disorder diagnosis. As its name implies, Autism Spectrum Disorder (ASD) represents a spectrum of symptoms, behaviors and associated features that medical science generally refers to as autism. It is the goal of the "Kids First" initiative to create a detailed classification of ASD that will more accurately reflect each individual's behavior and personality. With this new approach, researchers will be able to dig beyond the surface features of the disorder, to enact personalized, targeted approaches for care and interventions that will be more successful than what is available today.
