The purpose of the study is to determine whether the continuing detection of cell-free plasma tumor DNA (ptDNA), circulating tumor cells (CTCs), and cytokines (chemicals that help the immune system communicate) in the blood can help to better evaluate the status of a patients cancer over the course of therapy.

We want to test adults with sickle cell disease, using both the conventional in-person Montreal Cognitive Assessment (MOCA) and, within 2-4 months, the abbreviated 'MOCA-blind', which can be given remotely. In this way we can begin to evaluate whether these tests are sensitive to similar degrees of impairment when given remotely compared with in-person in people with sickle cell disease (SCD).

The purpose of this study is to understand how the COVID-19 pandemic has affected the patients, work and jobs of doctors, nurses, dentists, psychologists and other health care workers in community health centers, health departments and other practices that serve poor and at-risk people.

The Back Pain Consortium (BACPAC) Research Program, a component of the NIH HEAL Initiative, is conducting a range of studies to better understand and treat chronic low back pain.  This online questionnaire is forclinicians who treat patients with low back pain and will gather information on how they assess their patients, how they decide on a treatment approach(es), and the research needed to improve care and outcomes for these patients. This information will be used by BACPAC researchers in the development of future research studies.

Individuals who suffer anterior cruciate ligament (ACL) injuries are at an increased risk of developing knee osteoarthritis, a condition that results in chronic pain and disability. The purpose of this research study is to determine if adding vibration to standard rehabilitation following ACL reconstruction surgery improves gait biomechanics (how your joints move while walking); muscle function; symptoms, disability, and quality of life; and indicators of knee joint health more effectively than rehabilitation alone.

Primary care and behavioral health providers who accept patients on Medicaid will be surveyed regarding their satisfaction with the current fee for service payment model and the managed care payment model that NC Medicaid is transitioning to.

The purpose of this research study is to learn about how family advocates/specialists/support workers perceive the families they work with and how they support their partnerships with diverse families.

This purpose of this activity is to assess whether validated newborn indicators are feasible to implement in health facilities in Bangladesh.

The Autism Research program is an on-going project that has 2 components. One involves permission to conduct Records Reviews of client data and the other is a Research Registry for permission to contact subjects about future research studies. The purpose of both components is to support research in the field of autism and to provide information to help others with this disability. The Records Review answers research questions based on existing subject records. The Research Registry assists research investigators with recruitment of subjects and confidentiality of subjects. The risk is not more than minimal.
