BACKGROUND Preliminary evidence suggests that meditative exercise may have benefits for patients with chronic systolic heart failure (HF); this has not been rigorously tested in a large clinical sample. We sought to investigate whether tai chi, as an adjunct to standard care, improves functional capacity and quality of life in patients with HF. METHODS A(More)
Those with high baseline stress levels are more likely to develop mild cognitive impairment (MCI) and Alzheimer's Disease (AD). While meditation may reduce stress and alter the hippocampus and default mode network (DMN), little is known about its impact in these populations. Our objective was to conduct a "proof of concept" trial to determine whether(More)
BACKGROUND We examined the patterns of nonvitamin dietary supplement (NVDS) use among adult prescription medication users in the United States. METHODS Using the 2002 National Health Interview Survey, we analyzed factors associated with NVDS use and prescription medication use in the prior 12 months with descriptive, chi(2), and logistic regression(More)
This is the second in a series of two articles that look at the lessons for clinical medicine from systems biology. I n the fi rst article in this series, we examined the reductionist approach that pervades medicine and explained how a systems approach (as advocated by systems biology) may complement it [1]. In order for a systems perspective to have any(More)
This is the fi rst in a series of two articles that look at the lessons for clinical medicine from systems biology. S ince Descartes and the Renaissance, science, including medicine, has taken a distinct path in its analytical evaluation of the natural world [1,2]. This approach can be described as one of " divide and conquer, " and it is rooted in the(More)
OBJECTIVE To conduct a systematic review of the published literature on the efficacy and safety of herbal therapies and vitamin/mineral supplements for glucose control in patients with diabetes. RESEARCH DESIGN AND METHODS We conducted an electronic literature search of MEDLINE, OLDMEDLINE, Cochrane Library Database, and HealthSTAR, from database(More)
PURPOSE To examine the effects of a 12-week tai chi program on quality of life and exercise capacity in patients with heart failure. METHODS Thirty patients with chronic stable heart failure and left ventricular ejection fraction < or =40% (mean [+/- SD] age, 64 +/- 13 years; mean baseline ejection fraction, 23% +/- 7%; median New York Heart Association(More)
OBJECTIVE To assess the effects of a 12-week Tai Chi exercise program on sleep using the sleep spectrogram, a method based on a single channel electrocardiogram (ECG)-derived estimation of cardiopulmonary coupling, previously shown to identify stable and unstable sleep states. METHODS We retrospectively analyzed 24-h continuous ECG data obtained in a(More)
Our objective was to determine patterns, reasons for, and correlates of complementary and alternative medicine (CAM) use in US adults with common neurological conditions. We compared CAM use between adults with and without common neurological conditions (regular headaches, migraines, back pain with sciatica, strokes, dementia, seizures, or memory loss)(More)
