4 Clinical Trials for Various Conditions
Goal: The investigators propose to test the feasibility of giving the supplement coenzyme Q10 (Q10) improves symptoms and subjective health in an aging population. Rationale: Direct empirical evidence has supported benefit of Q10 to many symptoms such as fatigue, muscle pain, and cognition. In addition, Q10 has also been reported to benefit other symptoms including headaches, sleep disturbances, and breathing problems. This provides a strong rationale for testing whether Q10 will have similar benefit to these symptoms in an aging population. Method: 44 aging subjects will participate. The design is a 9 month, randomized, double-blind, placebo-controlled crossover study. Each subject will be "crossed over" between high dose Q10 (300mg), low dose Q10 (100mg), and placebo, receiving each agent for 3 month periods. Neither subjects nor investigators will know which substance each subject is receiving in which phase. Subjects will be randomly assigned to one of six arms. Assessments: Assessments will include feasibility of study, subjective quality of life, energy, and metabolic and lipid panels. Analyses will show whether Q10 led to improvements when compared to placebo; whether higher Q10 doses improved outcomes more than lower doses; and whether people with certain symptoms or characteristics get more benefit than people with other symptoms or characteristics.
Background: - Alzheimer s disease affects the brain and causes memory and thinking problems in older people. Macular degeneration (MD) is an eye condition. It is the leading reason that people over age 55 in the United States lose their central vision. Central vision is important for seeing fine details and for tasks like reading and driving. A feature of Alzheimer s disease is plaques in the brain. A feature of age-related MD is deposits in the retina in the eye. Researchers want to learn more about these diseases and find out if they are related. Objective: - To see whether there is a relationship between Alzheimer s disease and age-related macular degeneration. Eligibility: - People with or without Alzheimer s disease enrolled in another study. Participants must have someone to help them take part in this study. Design: * Participants will be screened through the other study. They will have 1 visit. The tests will take about 3 hours. * Participants will answer questions about their medical and eye history. * Participants will have an eye exam to test how well they see. Their eye pressure will be measured and their eye movements will be checked. * Participants will get eye drops to dilate their pupils. Researchers will take pictures of the retina and the inside of the eye. Researchers may measure the thickness of the retina. * Participants will continue to receive care from their regular eye doctor during and after the study.
To investigate whether patients with chronic-phase chronic myeloid leukemia (CP-CML) previously treated with interferon-alpha (IFN) and presently on a tyrosine kinase inhibitor (TKI) (imatinib mesylate, dasatinib, or nilotinib) with achievement of a complete cytogenetic and at least a major molecular remission, are able to discontinue therapy and maintain a durable remission. Relapse-free survival (RFS) rate at 1 year after discontinuation of TKI will be the measurement of this objective.
1. To show that patients with greater pain sensitivity will show greater improvement in their symptoms (self-reported pain intensity, mood, sleep, and quality of life) than those with lower pain sensitivity, based on QST, after taking milnacipran. 2. To compare outcome differences (pain intensity, mood, activity interference, sleep, and side effects) with those patients who are either taking or not taking opioids for their pain 10 weeks after being prescribed milnacipran. 3. To show that patients who are older, male, with more medical comorbidities, greater disability, and longer pain duration will report less improvement (pain, mood, sleep, health-related quality of life) and treatment satisfaction while taking milnacipran compared with others without such characteristics.
