The investigators propose a pilot randomized trial to gather preliminary data to test the hypothesis that Fisetin will reduce abundance of senescent cells in blood, skeletal muscle, and both subcutaneous and inter muscular adipose tissue and improve 6-minute walk distance in 34 people with peripheral artery disease (PAD). the investigators will determine whether greater declines in abundance of cells with senescent markers are associated with greater improvement in 6-minute walk distance in people with peripheral artery disease. In exploratory analyses, the investigators will assess whether Fisetin reduces interleukin-6 (IL-6) and novel senescent markers in adipose tissue, muscle, and/or blood. Read Less

Using a three-armed design the investigators will test whether participants in the Mindboba online application experience significantly greater improvements as compared to participants in the active control (online app based on Cognitive Behavioral Therapy) and participants in the business-as-usual control. The outcome measures are self-reported social problem-solving, self-efficacy, stress, depression, anxiety, attitudes towards seeking mental health, and knowledge. Read Less

Osteosarcoma is very rare cancer of the bone. The investigator started the BOOST registry and biobank to make sure every patient has the opportunity to participate in research. Read Less

This study will test the use of video ophthalmoscope to provide information about intracranial pressure without the use of invasive methods, anesthesia or contact with the eye. Read Less

This feasibility study will evaluate how well hyperpolarized 13C pyruvate magnetic resonance imaging (MRI) scan works in predicting tumor aggressiveness in participants with renal tumors. Hyperpolarized 13C pyruvate is a non-radioactive substance with potential usage in the diagnostic imaging of tumors. Hyperpolarized 13C pyruvate MRI may help doctors determine non-invasively whether a kidney tumor is a benign tumor or cancer, and if cancer, how aggressive it is. This may help doctors and participants with renal tumors in the future to make better treatment decisions. Read Less

Background: Suicide is the second leading cause of death for young people ages 10-24 years. There is no gold standard for evaluating suicidal thoughts and behaviors in young people with autism spectrum disorder (ASD) or other neurodevelopmental disorders (NDD). Also, youth with ASD/NDD are often excluded from many research studies. Because of this, researchers need more data. They want to make sure they are asking the best questions for young people in clinics such as the National Institute of Mental Health (NIMH) clinic. They want to make sure they have the best data to determine if a person is at risk for hurting or killing himself or herself. Objective: To develop and assess the efficacy of a suicide screening tool for people with ASD/NDD. Eligibility: Youth ages 8 to 17 who are engaged in assessment or treatment at the NIMH for ASD or other NDD Design: Participants will fill out 4 questionnaires during a 1-hour meeting with study staff. They will answer questions about how they have been feeling. They will be asked if they think about or plan to hurt or kill themselves. They will also be asked if they have ever thought about it or planned it in the past. Other questions will assess their understanding of death. Participants can take a break if needed. Parents of the participants will be asked similar questions. Parents will be informed if their child has current thoughts of suicide. About 1 week after the initial assessment, parents will be contacted to fill out a follow-up questionnaire. It will take about 10 minutes to complete. Read Less

This phase I trial investigates the effects of influenza vaccine in treating patients with stage I-IV melanoma. While intramuscular administration of influenza vaccine provides immunization against the influenza virus, giving influenza vaccine directly into the tumor (intralesional) may decrease the size of the injected melanoma tumor, or the extent of the melanoma within the body.

As the prevalence of obesity rises in the U.S., so does the incidence of pediatric type 2 diabetes (T2D), which is associated with more aggressive disease progression than in adults. From 2002-2012, the incidence of T2D in youth increased by 7% annually in the U.S. Compared to adults. T2D in adolescents is a much more progressive and recalcitrant disease, characterized by more rapid deterioration of β-cell function and earlier incidence of exogenous insulin dependence and diabetes-related comorbidities. A potential factor that drives the rapid progression of adolescent T2D is obesity (body mass index \[BMI\] \>95th percentile. Effective and safe treatments targeting both obesity and β-cell dysfunction are needed for pediatric T2D. In 2012, the FDA approved the use of Phentermine/Topiramate for the treatment of obesity in adults. This orally-administered medication is available in mid- (phentermine 7.5 mg; topiramate 46 mg) and high- (phentermine 15 mg; topiramate 92 mg) doses, administered once per day. In a meta-analysis, phentermine/topiramate was shown to be one of the most effective obesity medication currently available. A large dose-ranging trial in adults evaluating phentermine and topiramate as monotherapies vs. phentermine/topiramate demonstrated superior efficacy of the combination with an acceptable safety profile. Results from a large phase III clinical trial demonstrated placebo-subtracted weight loss of \>9% with treatment for one year at the top dose. Importantly, a separate trial demonstrated that the treatment effect is durable out to at least two years.41 The most common side effects in these trials were paresthesia, dizziness, dysgeusia, insomnia, constipation, and dry mouth. Improvements were noted in blood pressure, lipids, glucose, insulin, HOMA-IR, C-reactive protein, and adiponectin. Read Less

Deep brain stimulation (DBS) is used to treat epilepsy in cases where patients are medically refractory and are not candidates for surgical resection. This therapy has been shown to be effective in seizure reduction, yet very few patients achieve the ultimate goal of seizure freedom. Implantable neural stimulators (INSs) have many parameters that may be adjusted, and could be tuned to achieve very patient specific therapies. This study will develop a platform for stimulation setting optimization based on power spectral density (PSD) measures. Read Less

The study will examine whether the benefits of brain stimulation on mental functioning can be enhanced if an individual is actively engaging the target brain networks while receiving brain stimulation. The study includes two separate sessions and people will complete either a cognitive task or a perceptual task while receiving transcranial magnetic stimulation. The study will measure change in brain function with EEG. Read Less

The goal of this trial is to see if active surveillance monitoring and hormonal therapy in patients diagnosed with ductal cell carcinoma in situ (DCIS), an early stage of breast cancer, can be an effective management of the disease. Participants will be asked to receive control hormonal therapy or an investigational hormonal therapy treatment. Participants will be asked to return for evaluation with MRI at three months and six months. Depending on the evaluation participants will have the option to continue on the treatment. If the evaluation suggests surgery is recommended, the participant will discontinue the study treatment and will undergo surgery. In addition to the treatment and MRI evaluation, participants will be asked to provide blood sample to understand their immune status, provide saliva sample for genetic testing, provide the study with a portion of the tissue or slides generated from tissue removed during surgery performed as part of their standard of care.

This study aims to define the natural history of men at high genetic risk for prostate cancer on the basis of specific germline genetic mutations, family history, or Black/African ancestry and evaluate the utility of prostate MRI as a screening tool. The hypothesis is that this targeted population of men are at elevated risk of developing prostate cancer compared to the general population, and enhanced screening with MRI will enable early detection and diagnosis of potentially aggressive prostate cancer, characterization of the penetrance of specific mutations, and potentially identify new genetic risk mutations.
