The purpose of the study is to see how restricting the eating window (called time-restricted eating) might affect eating habits, weight, and blood measures compared to reducing food intake. Time-restricted eating means that people would have a daily 8 hour eating window during which time they can eat whatever they want. Outside of the eating window, people would only take water and your medications. We expect that participants will be in this research study for about 7 months.

This study explores the associations between maternal stress, breastmilk composition, and feeding and neurodevelopment for preterm infants in the NICU and at 4 months corrected age.

The goal of this study is to better understand how drinking alcohol may lead to oral cancers. Acetaldehyde, a chemical formed when the body breaks down alcohol, is believed to play an important role. This study will measure acetaldehyde and DNA damage levels in the mouth of participants after a low dose of alcohol. The levels will be compared between three groups, all having different degrees of risk for developing oral cancer, and with non-drinkers to identify DNA damage that might be important to cancer formation. We also want to understand how alcohol can affect the bacteria in our mouths and how that might impact oral DNA damage.

The purpose of this study is to learn about a new way of managing hypertension using a wireless blood pressure monitor and a smartphone. The goal is to improve hypertension care in older adults with memory loss or mild dementia in partnership with their caregiver.

A pilot study looking at an adult-based non-pharmacologic interventional trial in collaboration with psychologist who has expertise in cognitive behavioral therapy (CBT) for adolescents with chronic disease and intellectual disability and developing processes towards independence in non-Sickle Cell Disease settings.

The purpose of this study is to determine whether active Vagal Nerve Stimulation (VNS) Therapy is better than no stimulation VNS Therapy in improving health outcomes for subjects with Treatment-Resistant Depression (TRD). All participants in this study will receive a VNS Therapy surgical implant, which works to reduce the symptoms of depression by sending mild electrical pulses to the vagus nerve in the neck. The vagus nerve is connected to areas of the brain associated with controlling the mood. Data will be collected on responses to study treatments, quality of life, productivity, and use of healthcare services.

The purpose of this study is to determine if replacing the mitral valve without open-heart surgery is as safe and effective as standard mitral valve surgery in patients with similar medical conditions. This system allows a bioprosthetic mitral valve (investigational valve) to be implanted through a long, thin, flexible tube that is inserted through an incision in the side of the chest or through an incision made in the groin area and through a vein in the leg. Participation in the study is expected to last approximately 5 years from the day the valve is implanted.

The HEALEY ALS Platform Trial is a research trial that tests the safety and effectiveness of multiple treatments in ALS. A regimen is a specific course of treatment, each with a different study drug. We are doing this research to find out if different treatments have an effect on Amyotrophic Lateral Sclerosis (ALS). We also want to find out if these treatments are safe to take without causing too many side effects.

This study will test whether adding in daily weighing (5-7 days per week) is helpful in weight loss. In adults, it has been found to be helpful to have individuals who are obese to be more successful with their weight loss efforts if they weigh themselves at home every day. We want to see if this could be helpful in children as well. This research will last for about 12 weeks (3 months).

The goal of this study is to learn more about how people make health-related decisions. Participants will complete two remote visits over Zoom, and answer questions about their beliefs, experiences, and health decisions they have made. They will also complete online computerized tasks. Total participation time is 2-3 hours.

Paired sound and electrical stimulation can alter how the brain encodes sounds and the perception of sounds, as shown in emerging evidence from animal studies. The aim of this study is to develop measures for paired stimulation that can be used reliably. These measures assess the following aspects of hearing: basic hearing sensitivity and cochlear health, perception of loudness and pitch, and perception of speech and music/complex sounds. This will lead to a greater understanding in the hearing science community about how multisensory stimulation can alter activity in the auditory system and sound perception, which may lead to new techniques for improving hearing disorders.

The purpose of the study is to better understand the experiences of healthy lifestyle behaviors (i.e., sleep and physical activity), and receive feedback on a sleep intervention that aims to improve sleep among African American adults who do not get enough sleep. Sleep is vital to engaging in a healthy lifestyle, living longer, and feeling energized throughout the day. This research will compare a sleep intervention program (“Sleep Intervention Group”) to a healthy homes education program (“Control Group”) to see if there are changes in sleep and physical activity among those in the Sleep Intervention Group. We expect that participants will be in this research study for about 6 weeks.

Humanitarian use devices are medical devices approved by the FDA for the treatment of medical conditions affecting fewer than 4,000 patients per year. The FDA reviewed the safety of the device and determined that the probable health benefits outweigh the risks of injury or illness from its use. Effective treatment of symptoms, however, has not been studied in formal clinical trials. Medtronic DBS Therapy delivers electrical stimulation to areas in the brain to help control symptoms of various movement disorders. You may be a candidate for Medtronic DBS Therapy for Dystonia if you have been diagnosed with chronic, intractable (drug refractory) primary dystonia. You or your third party payer (health insurance, Medicare, Medicaid or other) must provide payment for hospital, office and other medical costs related to this therapy.

The purpose of this study is to measure the compliance, usability, and satisfaction of an at-home, multi-modal stimulation device in a diverse population of people with chronic lower back pain (cLBP) compared to a group of participants who are engaging in integrative health practices. The multi-modal device will include a combination of electrical stimulation, auditory stimulation, and integrative-health techniques, including mindfulness breathing, health coaching, and reflective journaling. The multi-modal device creation is based on prior knowledge in lower back pain treatment, which includes electrical stimulation of the back (Transcutaneous Electrical Nerve Stimulator or TENS) and integrative health modalities. Findings from this usability pilot study could help refine the approach and the multi-modal device for a future intervention study in cLBP participants.

This study seeks to understand visual perception in people with Visual Snow Syndrome and how this relates to brain function.

To maintain a biorepository (sample bank) of biological samples from different tobacco users and non-users to investigate how tobacco and nicotine products affect our bodies. The samples will be used by researchers to develop methods to look for biological “markers” (biomarkers), or chemical changes in the body, that occur due to tobacco or nicotine exposure. The goal is to eventually use these biomarkers to improve detection, prevention, and treatment strategies for tobacco-related diseases.

We are looking at how an 8-week exercise program of walking for 30-45 minutes 3 times/week affects the body. This study is for people who are prediabetic and overweight or obese. We will compare the exercise group to a group that didn’t participate in the exercise to see if there are differences in gut microbes, body measurements, and blood work.

We are exploring ways to promote healthy lifestyles during stroke rehabilitation using a web-based rehabilitation program. The purpose of this study is to compare two intervention approaches: teleABLE and Healthy Lifestyles Education. Both interventions are delivered using video visits, so participants can complete all study activities from home

We are recruiting only healthy participants who do not have REM sleep behavior disorder. The information gained from this study will help the investigators understand more about REM sleep behavior disorder (RBD), and the possible underlying neurologic disorders that can cause RBD.

This protocol will characterize the effects of deep brain stimulation (DBS) location (both adverse and beneficial) on motor signs in people with Parkinson’s disease (PD). This information can be used to inform future DBS protocols to tailor stimulation to the specific needs of a patient. If targeted dorsal GP stimulation is shown to significantly improve motor features that are typically resistant to dopamine replacement therapy, these experiments will likely have major impact on clinical practice by providing a potential strategy to treat medically intractable symptoms.

The purpose of this research is to better understand balance and walking in patients with Parkinson’s Disease. This research study uses small wearable devices that attach to clothing and can measure the body’s location while performing walking and balance tests.

We are looking at the addition of nivolumab to chemotherapy compared to usual treatment (chemotherapy alone) for the treatment of anal cancer that has spread to other places in the body. Immunotherapy, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells. Giving nivolumab with chemotherapy may help doctors find out if the treatment is better or the same as the usual approach.

PR001A is designed to deliver a normal GBA1 gene copy into the body to increase the activity of GCase, which is low in Type 2 Gaucher Disease (GD2) patients. The new GBA1 gene will remain a child’s body cells for many years and possibly for the rest of their life. A participant will need one surgery during which the study drug will be given and will stay in the hospital for at least 48 hours following the surgery.

More than 65% of people with lower extremity peripheral artery disease (PAD) are overweight or obese. Overweight or obese people with PAD have greater functional impairment and faster functional decline than normal weight people with PAD. Walking exercise is first line therapy to improve walking performance in PAD. However, our NHLBI-funded observational longitudinal study of functional decline in PAD showed that overweight and obese PAD participants who combined weight loss with walking exercise had significantly less functional decline than those who walked for exercise but did not lose weight. Therefore, we hypothesize that among people with PAD who are overweight or obese, a weight loss intervention combined with exercise will improve walking ability more than exercise alone. However, the effects of intentional weight loss in overweight or obese people with PAD are unknown and may not be beneficial if weight loss exacerbates PAD-related sarcopenia. Behavior change that achieves sustained weight loss is particularly challenging in older obese people with chronic disease. Therefore, among people with PAD and BMI>28 kg/m2, we will conduct a randomized clinical trial to test the hypothesis that a weight loss intervention combined with walking exercise achieves greater improvement in functional performance than exercise alone at 12-month follow-up.

The purpose of this study is to evaluate the long-term safety and effectiveness of Skytrofa treatment in children growth hormone deficiency. Patient care will follow the normal treatment practices at the clinic. No additional visits will be performed beyond the usual clinical practice.

The purpose of this study is to describe current knowledge and opinions about anal cancer screening among men who have sex with men (MSM), as well as their experience receiving guideline-compliant care aimed at anal cancer risk reduction using a large-scale survey disseminated via social media.

The purpose of the study is to test new biomarkers of amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) using MRI scans at 3 tesla (3T). Identifying biomarkers of a disease can lead to a better understanding of the disease as well as improved treatments.

We are looking at how well letrozole with or without paclitaxel and carboplatin works in treating patients with stage II-IV low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum. Letrozole is an enzyme inhibitor that lowers the amount of estrogen made by the body and may stop the growth of tumor cells that need estrogen to grow. We will compare the effectiveness of the two different treatments.

This study identifies the bio-behavioral predictors and correlation of responses to Comprehensive Behavioral Intervention to Tics (CBIT) in young people with tic disorder.

TrialNet is an international research group dedicated to the study, prevention, and early treatment of Type 1 diabetes. Type 1 diabetes is now understood as a disease that develops over time in stages. Stage 1 starts with the appearance of having two or more autoantibodies. This is followed by Stage 2, which is the development of abnormal blood glucose levels. Stage 3 is the clinical diagnosis of Type 1 diabetes. This study will help us learn more about how Type 1 diabetes occurs through the screening of diabetes-related autoantibodies and monitoring individuals who have tested positive for these autoantibodies.
