Filter by:The purpose of this study is : - to look for changes induced by aging in a population of old subjects, during silent word generation tasks studied by fMRI. - to look for a possible link between these changes and alterations in language
The purpose of this study is to measure how long the improvement in the immune system lasts in older people after they have been vaccinated, and to examine the immune response in older people who get vaccinated a second time.
Background: - The Baltimore Longitudinal Study of Aging (BLSA) is a clinical research program on human aging that began in 1958. Volunteers of different ages join the study when they are healthy, and have follow-up visits for life. Visits last for multiple days. Participants are evaluated for many physical elements as well as for brain function. Physical tests are given. Information on mood, personality, and social aspects of life is also collected. This program has contributed more than any other research project to our understanding of aging. Objectives: - To characterize the many aspects of the aging process and learn how people can successfully adapt to aging. Eligibility: - Healthy individuals at least 20 years old. Design: - Participants will receive a booklet and video describing the tests they will take. - During a 3-day visit at the study hospital, participants will take the following tests: - Urine will be collected for 24 hours. Blood samples will be taken. A small piece of muscle tissue may be collected by a needle. - A medical questionnaire and a physical exam will be given. - Participants hearts will be tested, including with blood pressure tests and electronic monitors. They will breathe into a tube to test their lungs. - Participants will perform several exercises, including treadmill walking. - Vision, hearing, and taste will be tested. - Bone and joint X-rays may be taken. - Imaging tests will be given, such as an MRI. - Participants will answer questions to test their mental abilities. - Participants will return for follow-up visits every few years for life. The tests listed above will be given at every visit.
The study tests the hypothesis that estradiol administration exacerbates the effects of the stress hormone cortisol on cognition and mood for postmenopausal women. This randomized, placebo-controlled, double-blind study was designed to examine the effects of an eight-week trial of transdermal estradiol replacement therapy (0.10 mg/day) in combination with 4 days of oral hydrocortisone (90 mg/day in 3 daily doses of 30 mg per dose) in the last week of hormone therapy on cognition and mood in healthy postmenopausal women. Forty cognitively healthy postmenopausal women were randomized to receive either placebo or estradiol skin patches for 8 weeks. In the middle of the 7th week (day 57), subjects in each group were again randomized to receive either a placebo tablet or an oral hydrocortisone tablet 3x/day for 4 days. Memory testing and blood collection occurred at baseline, at week 4, and again at week 8.
This study will examine the feasibility and short and-long-term efficacy of a web-based telehealth intervention with community-dwelling older adults who have been diagnosed with type 2 diabetes. Effectiveness will be evaluated using multiple measures within three different domains: 1) physical (glycosylated hemoglobin [HbA1C], weight, and lipid levels); 2) behavioral (monitoring blood glucose levels, feet inspections, diet, and exercise frequency), and 3) psychosocial (depression, quality of life, social support, and adjustment to diabetes). This is a randomized controlled trial of a web-based telehealth intervention designed to improve self-management behaviors in a group of community dwelling older diabetics. Two groups of participants will be recruited and randomized over a four-month period during years 01 and 02. Participants in the control group will receive standard diabetic care provided by their provider. Participants in the intervention group will receive computer training in the participant's home in how to access and utilize the web-based telehealth study webpage. The intervention will consist of a program designed and delivered via the Internet to improve the participants' diabetes self-management behaviors using behavioral and motivational strategies and cues to modify perceptions of self-efficacy and beliefs regarding the ability to affect the progress of the disease and change personal behavior.
