8 Clinical Trials for Various Conditions
This current randomized, double-blind, comparator-controlled, cross over study investigates the efficacy and safety of RiaGev™ via evaluation of NAD+, ATP, glucose, insulin, glutathione, and cortisol levels in healthy adults of ages 36-65.
During menopause, there is a decrease in a hormone estrogen, which leads to aging of the vagina. Vaginal aging includes changes in the type and amount of healthy bacteria in the vagina, inflammation and a breakdown of natural barriers that keep the vagina healthy and protected from infections. Some menopausal women develop a condition called vaginal atrophy, which causes vaginal dryness, irritation, pain with sex, and itching. We are testing whether an estradiol tablet placed inside the vagina will lead to fewer changes in the types of bacteria present in the vagina, improve vaginal atrophy symptoms and ultimately keep the vagina healthier for a longer. This is important for women with HIV as they are living longer, healthier, sexually active lives due to successful treatment with antiretrovirals.
This study will examine children with Hutchinson-Gilford Progeria syndrome, a genetic disease that causes many changes to the body over time, including heart disease, bone changes, hair loss, and joint and skin changes. Often called a "premature aging" disease, progeria does not mimic aging completely. This study will examine which body systems are affected in progeria and how each system is affected over time in order to try to develop new treatments. Patients with progeria who are between 6 months and 70 years of age and who are able to travel to the NIH in Bethesda, Md., may be eligible for this 5- to 10-year study. Participants come to the NIH Clinical Center for evaluation every 2 years. Each 4-5 day visit includes the following tests and procedures: * Medical history and physical examination * Blood tests to analyze cardiovascular risk factors, blood counts, blood chemistries, and for research * Urine tests for sugar and proteins * Photographs to study growth problems * X-ray studies to determine bone density and body composition, such as body fat and muscle * Electrocardiogram (EKG) and echocardiogram (heart ultrasound) to study the heart and blood vessels * Lung function tests to measure energy consumption and lung capacity * Skin biopsy (surgical removal of a small skin sample) to examine cellular changes * Hearing tests * Eye examination to evaluate eyesight, eye pressure and structures of the eye * Physical therapy evaluation with stretching and exercises to measure how the joints bend and straighten * Dental examination, including X-rays * Meeting with a nutritionist who will track the patient's food intake and take body measurements * Magnetic resonance imaging (MRI) for patients who are old enough to undergo the procedure without sedation. This test uses a magnetic field and radio waves to examine body organs. For this test, the patient must lie still in the scanner, a narrow cylindrical tube. Patients are provided the results of their medical tests. Information about the patient is submitted to the PRF Cell and Tissue Bank in Peabody, Massachusetts.
This pilot open-label study examines the effects of a combination of dasatinib plus quercetin - two drugs that have known senolytics properties - on physiological aging in older individuals with depression or schizophrenia.
It is estimated that by 2016, nearly 50% of HIV-positive individuals in the US will be aged 50 or older, and up to 60% of those will experience some degree of cognitive impairment as they age. The purpose of this study is to evaluate the contribution of the neuronal cholinergic receptor system to the cognitive impairments seen in adults aging with chronic HIV Infection. By using anti-cholinergic challenge drugs to reversibly "stress" cognitive functioning, the investigators hope to understand whether the presence of the HIV virus in the brain impairs the neural system necessary for normal cognition, more than would be expected from normal cognitive aging.
Consenting women with evidence of poor ovarian reserve will be randomly assigned to treatment with either Platelet Rich Plasma (PRP) or Platelet Poor Plasma (PPP).
The experimental focus of this project is on the interaction of DHEA treatment on pregnancy in women with open tubes, fertile male partners and evidence of premature ovarian failure.
This purpose of this study is to gain information about normal ovarian function that will be useful in developing a test for early detection of ovarian failure. The ovaries produce female hormones, such as estrogen, that are important in maintaining a woman's health. When the ovaries do not work properly, problems can develop. Unfortunately, there is no test that can detect ovarian failure early in its course. By the time premature ovarian failure is diagnosed in young women, two-thirds have already developed osteopenia (loss of some bone mass) and nearly one in ten have osteoporosis, a greater loss of bone mineral density that weakens bones and increases the risk of fractures. Women with normal ovarian function ages 18 to 55 and postmenopausal women 60 years of age or older may be eligible for this study. Candidates will be screened with a medical history, physical examination, blood tests and vaginal ultrasound examination. For the ultrasound study, a probe that emits sound waves is inserted into the vagina, and the sound waves are converted to form images of the ovaries. The procedure is done with an empty bladder and takes about 10 minutes. After this screening visit (Visit 1), those enrolled in the study will return to the NIH Clinical Center for the following additional procedures: Visit 2-Will be scheduled between days 3 and 5 of the menstrual cycle (for women who are still menstruating). Participants will have blood tests to measure hormone levels and to check for pregnancy, and will have another transvaginal ultrasound examination. They will then receive an injection of a synthetic form of follicle stimulating hormone (FSH), a hormone the body makes normally. Visits 3 and 4-Will be scheduled 24 and 36 hours after the FSH injection given during Visit 2 for collection of blood samples. Visit 5-Will be scheduled 48 hours after the FSH injection for additional blood sampling and a final transvaginal ultrasound examination.
