This study will be the first to evaluate the dose-dependent effects of t-PBM in amnestic Mild Cognitive Impairment (aMCI) (CDR of 0.5-1, FAST 1-3; age 65-85) in a randomized clinical trial of 8 weeks of t-PBM vs. sham. At screening, all subjects will complete initial neuropsychological testing. To elucidate mechanisms of action of t-PBM, prior to treatment, subjects will undergo neuroimaging related to critical features of AD: tau 18F MK-6240 load (PET), measures of brain bioenergetics (31P-MRS), and functional connectivity (rs-fMRI). Subjects will also undergo an open label t-PBM session performed during fMRI to detect BOLD changes with t-PBM. Subjects will then be randomized to t-PBM/sham and complete treatments in two participating centers (NYU/NKI acting as a single center, and MGH), ~10 min per day, 3 days per week, for 8 weeks. t-PBM will be administered via pulsed, 808nm wavelength laser delivery to the forehead bilaterally (at standard EEG electrode positions F4, F3).

Globally, over 1 million babies are born to mothers with HIV each year. With the advent of prenatal antiretroviral therapy, up to 98% of these individuals may be HIV-exposed uninfected (HEU). A growing literature suggests that in utero HIV exposure - even in the absence of subsequent infection - may be associated with adverse health outcomes in infancy and childhood. However, there is little information about the long-term health implications of in utero HIV exposure later in life, such as into adulthood. In this study, for the first time, we seek to prospectively evaluate metabolic and immune indices among HEU young adults as compared to well-matched HIV-unexposed uninfected controls. This study serves as a necessary first step toward optimizing clinical care for this expanding and aging HEU population, including the implementation of novel screening and prevention strategies.

This trial aims at understanding the mechanisms of optimized transcranial direct current stimulation (tDCS) (16 tDCS sessions combined with exercise)] on pain control. Optimized tDCS can lead to stronger engagement of the endogenous pain regulatory system that will ultimately lead to increased pain relief in patients with fibromyalgia (FM). Therefore, the investigators designed a 2x2 factorial mechanistic trial [tDCS (active and sham) and aerobic exercise (AE) (active and control)] to evaluate the effects of 4 weeks of tDCS coupled with exercise on the endogenous pain regulatory system assessed by conditioned pain modulation (CPM) and central sensitization as assessed by temporal slow pain summation (TSPS), and compared to either intervention alone and to no intervention.

HIV-infected individuals treated with antiretroviral medications are living longer, but have an increased risk of heart disease when compared to non-HIV-infected individuals. A hormone called aldosterone, which regulates blood pressure and sodium balance, is elevated in the HIV population in association with with increased belly fat and altered glucose metabolism. Elevations in aldosterone hormone may also be associated with abnormal blood flow, inflammation, and coronary plaque in the heart. This study is being conducted to evaluate whether therapies to reduce the actions of aldosterone may decrease the burden and progression of heart disease in the HIV population.

Background: Primary Liver Cancer is the second most common cause of cancer-related death worldwide. It is the cancer with the fastest rising incidence and mortality in the United States. Researchers want to learn more about liver cancer to help them design better treatments. Objective: To better understand liver cancer. Eligibility: People ages 18 and older who have liver cancer and had or are planning to have immune therapy Design: Participants will be screened with a review of their medical records. They will be asked about their medical history and test results. Participants will come to the NIH Clinical Center. During this visit, their medical records, test results, imaging studies, and tissue samples (if available) will be gathered. Participants will learn the results of a test to see if they have any mutations known to be connected to cancer. They will learn if there are treatment options for them. Participants will give blood, urine, and stool samples or rectal swabs. Participants will not have follow-up visits just for this study. If they join another NIH research study and have visits for this other study, their medical records; test results; and blood, urine, and stool samples may be collected. This will occur about every 3 months. If they have a biopsy or surgery on another study or as part of treatment and there is leftover tissue, researchers would like to collect some of that tissue. Participants will be contacted every 6 months by phone or e-mail. They will be asked about their health. They will provide any medical records, test results, and imaging studies. Participants will be followed on this study for life.

This research study is a genomic profiling and repository study for children and young adults who have leukemia, myelodysplastic syndrome (MDS) or myeloproliferative syndrome (MPS). Genes are the part of cells that contain the instructions which tell cells how to make the right proteins to grow and work. Genes are composed of DNA letters that spell out these instructions. Genomic profiling helps investigators understand why the disease develops and the instructions that led to its development. Understanding the genetic factors of the disease can also help investigator understand why the disease of some people can respond to certain therapies differently than others. The genomic profiling will be performed using bone marrow and blood samples that either have already been obtained during a previous clinical procedure or will be obtained at the time of a scheduled clinical procedure. Studying the genetic information in the cells of these samples will provide information about the origin, progression, and treatment of leukemia and myeloproliferative syndromes and myelodysplastic syndrome. Storing the bone marrow and blood samples will allow for additional research and genomic assessments to be performed in the future.
