Arthritis is the most common cause of disability among U.S. adults and is particularly common among persons with multiple chronic conditions. In 2003, arthritis in the United States resulted in an estimated $128 billion in medical-care costs and lost earnings. To update previous U.S. estimates of the prevalence of doctor-diagnosed arthritis and(More)
Low 25-hydroxyvitamin D [25(OH)D] levels have been linked to hip fracture in white women. To study the association of 25(OH)D with risk of fracture in multiethnic women, we performed a nested case-control study within the prospective Women's Health Initiative (WHI) Observational Study. Incident fractures were identified in 381 black, 192 Hispanic, 113(More)
Adiponectin and leptin are adipokines that influence bone metabolism in vitro and in animal models. However, less is known about the longitudinal association of leptin and adiponectin with fracture. We tested the hypothesis that low leptin and high adiponectin levels are each individually associated with fracture risk in a prospective cohort study in(More)
Quantitative computed tomography (QCT) can estimate volumetric bone mineral density (vBMD) and distinguish trabecular from cortical bone. Few comprehensive studies have examined correlates of vBMD in older men. This study evaluated the impact of demographic, anthropometric, lifestyle, and medical factors on vBMD in 1172 men aged 69 to 97 years and enrolled(More)
Cytokines play a major role in bone remodeling in vitro and in animal models, with evidence supporting the involvement of inflammatory markers in the pathogenesis of osteoporosis. However, less is known about the longitudinal association of inflammatory markers with hip fracture. We tested whether high receptor levels of proinflammatory cytokines are(More)
We tested the hypothesis that low leptin and high adiponectin levels are associated with higher rates of bone mineral density (BMD) loss among 3,075 men and women, aged 70–79, from the Health Aging and Body Composition Study. Results suggest that adiponectin, but not leptin, is a risk factor for bone loss in women. Adiponectin and leptin are hormones(More)
OBJECTIVE To update the projected prevalence of arthritis and arthritis-attributable activity limitations among US adults, using a newer baseline for estimates. METHODS Baseline prevalence data were obtained from the 2010-2012 National Health Interview Survey. Arthritis was defined as an answer of "yes" to the question "Have you ever been told by a doctor(More)
Fishes in the superorder Ostariophysi possess specialized epidermal cells that contain a chemical alarm cue. The alarm cue is released when the skin is damaged during a predatory attack. Therefore, the cue serves as a reliable indicator of predation risk to nearby conspecifics and ecologically similar heterospecifics with which it shares predators.(More)
The effects of vitamin D and parathyroid hormone (PTH) levels on incident fracture remain uncertain. To test the hypothesis that increasing serum 25-hydroxyvitamin D [25(OH)D] and decreasing PTH levels are associated with decreased risk of hip and any nonspine fracture, we conducted a prospective cohort study among 2614 community-dwelling white and black(More)
BACKGROUND Inpatient HIV/AIDS charges decreased from 1996-2000. This decrease was mainly attributable to treatment of HIV/AIDS patients with Highly Active Antiretroviral Therapy (HAART). This study aims to evaluate the trend in inpatient charges from 2000-2004. METHODS Rhode Island Hospital Discharge Data (HDD) from 2000 to 2004 was used. International(More)
