Unlabelled: In a large cohort of U.S. women aged 65 and older, we report the relationships of BMD measured at several sites, and subsequent fracture risk at multiple sites over > 8 years of follow-up. Although we found almost all fracture types to be related to low BMD, the overall proportion of fractures attributable to low BMD is modest.
Introduction: Although several studies have reported the relationship between bone mineral density (BMD) and subsequent fracture risk, most have been limited by short follow-up time, BMD measures at only one or two sites, or availability of data for only select fracture types.
Materials And Methods: In the multicenter Study of Osteoporotic Fractures (SOF), we studied the relationship of several different BMD measures to fracture risk of multiple types in 9704 non-black women aged 65 and older. We previously reported on the relationship of peripheral BMD measures to risk of several types of fracture during an average 2.2-year follow-up period. In this expanded analysis, we present results of the relationship of both peripheral and central BMD measures and fractures of multiple types during 10.4 and 8.5 years of follow-up, respectively. We also report population attributable risk (PAR) estimates for osteoporosis and risk of several types of fracture.
Results: Our results show that almost all types of fractures have an increased incidence in women with low BMD. However, hip BMD is somewhat more strongly related to most of the fracture types studied than spine or peripheral BMD measures. Nonetheless, the proportion of fractures attributable to osteoporosis (based on a standard definition of osteoporosis) is modest, ranging from < 10% to 44% based on the most commonly used definition of osteoporosis (BMD T-score < -2.5).
Conclusion: Finding effective prevention strategies for fractures in older women will require additional interventions beside preventions for bone loss, such as prevention of falls and other fracture risk factors.

Introduction: Septic arthritis, primarily caused by (), is a severe joint infection that leads to joint and bone damage. lipoproteins (LPPs) bind to Toll-like Receptor 2 (TLR2), inducing arthritis and localized bone loss. Aging affects TLR2 immune response to pathogens.

Objectives: The pathogenesis of premature ovarian insufficiency (POI) not only affects the ovarian structure and function but also gives rise to complications such as osteoporosis and dyslipidemia. Although low-intensity pulsed ultrasound (LIPUS) has been proven effective in treating POI, its impact on the associated complications remains unexplored. Therefore, this study aims to investigate the effects of LIPUS irradiation on osteoporosis and dyslipidemia in a mouse model of POI.

Previous studies suggest social support is associated with musculoskeletal health in later life. We explored this relationship further in community-dwelling older adults, by considering associations between different aspects of social support and musculoskeletal health in community-dwelling adults. Participants from the Hertfordshire Cohort Study reported level of confiding/emotional, practical, and negative support using the Close Persons Questionnaire.

The tumorigenic dose 50 (TD) is a widely used measure of carcinogenic potency which has historically been used to determine acceptable intake limits for carcinogenic compounds. Although broadly used, the TD model was not designed to account for important biological factors such as DNA repair and cell compensatory mechanisms, changes in absorption, etc., leading to the development of benchmark dose (BMD) approaches, which use more flexible dose-response models that are better able to account for these processes.

Patients undergoing dialysis are at risk of osteoporosis and sarcopenia because of mineral and bone disorders or malnutrition. Additionally, maintaining muscle mass is important to prevent osteoporosis. The psoas muscle mass index (PMI) was recently used to evaluate muscle mass.
