Cadmium (Cd) is the most potent nephrotoxic heavy metal and may affect bone; it also has a long biological half-life in the human body. This study was designed to assess the effect of environmental low-level Cd exposure on kidney function and bone in the general population. The subjects of this cross-sectional study were 1907 healthy Korean adults who had not been exposed to Cd occupationally. We analyzed the concentrations of Cd in the urine, markers of renal tubule damage, such as β2-microglobulin (β2-MG) and N-acetyl-β-D-glucosaminidase (NAG) activity in the urine, calculated the estimated glomerular filtration rate (eGFR) using serum creatinine, and measured bone mineral density (BMD)...

Osteoporosis is a common age-related disorder leading to an increase in osteoporotic fractures and resulting in significant suffering and disability. Inflammation may contribute to osteoporosis, as it does to many other chronic diseases. We examined whether inflammation is etiologically relevant to osteoporosis, assessed from bone mineral density (BMD), as a new potential target of intervention, or whether it is a symptom/biomarker of osteoporosis. We obtained genetic predictors of inflammatory markers from genome-wide association studies and applied them to a large genome wide association study of BMD...

BACKGROUND: HIV-infected (HIV-pos) male children/youth showed lower bone mineral density at sexual maturity than HIV-uninfected (HIV-neg) females. It is not known whether complications of HIV disease, including abnormal body fat distribution, contribute to lower bone accrual in male HIV-pos adolescents. METHODS: In a cross-sectional study, we evaluated the relationship between body composition (fat and lean mass) and bone mass in HIV-pos and HIV-neg children/youth and determined if it is modified by HIV status and sex...

BACKGROUND: Longitudinal studies showed conflicting results regarding the association between use of selective serotonin reuptake inhibitors (SSRIs) and bone mineral density (BMD). Therefore, we investigate the association between-duration of-SSRI use and BMD, and change in BMD ([INCREMENT]BMD). METHODS: Data from the population-based Rotterdam Study cohort (1991-2008) were used. In total, 4915 men and 5831 postmenopausal women, aged 45 years and older, were included, having measurement visits at 4- to 5-year intervals...

This pilot study enrolled 31 women who had breastfed exclusively for 6 months. Lumbar and thoracic BMD increased 4 and 5%, respectively. Femoral neck and total body BMD did not change. Return of menses and progestin-only pill use were two potential signals that predicted a greater increase in BMD. PURPOSE/INTRODUCTION: The skeleton is resorbed during lactation to provide much of the calcium content of milk. After lactation ceases, these deficits in skeletal mineral content are largely restored, such that lactation has a neutral or protective effect against the long-term risk of low bone mineral density (BMD), osteoporosis, and fragility fractures...

AIM: Osteoporosis and periodontitis are both chronic diseases characterised by bone loss. Potential association is of great clinical importance because of multifactorial aetiology and common risk factors. The aim of this study was to determine relationship between bone mineral density (BMD), tooth loss and periodontal status taking into account age, number of years since onset of menopause and educational level. With increasing age, number of years since onset of menopause and lower educational level, decreased BMD, deteriorating periodontal status and greater tooth loss are expected...

Adiponectin regulates various metabolic processes including glucose flux, lipid breakdown and insulin response. We recently reported that adiponectin receptor1 (adipoR1) activation by a small molecule reverses osteopenia in leptin receptor deficient db/db (diabetic) mice. However, the role of adiponectin in bone metabolism under the setting of post-menopausal (estrogen-deficiency) osteopenia and associated metabolic derangements has not been studied. Here, we studied the therapeutic effect of the globular form of adiponectin (gAd), which is predominantly an adipoR1 agonist, in aged ovariectomized (OVX) rats and compared it with standard-of-care anti-osteoporosis drugs...

Protein kinase D1 (PRKD1) is thought to play a role in a number of cellular functions, including proliferation and differentiation. We hypothesized that PRKD1 in bone marrow-derived mesenchymal stem cells (BMMSC) could modulate osteogenesis. In BMMSCs from floxed PRKD1 mice, PRKD1 ablation with adenovirus-mediated Cre-recombinase expression inhibited BMMSC differentiation in vitro. In 3- and 6-month-old conditional knockout mice (cKO), in which PRKD1 was ablated in osteoprogenitor cells by osterix promoter-driven Cre-recombinase, bone mineral density (BMD) was significantly reduced compared with floxed control littermates...

Diabetes mellitus and osteoporosis both are high prevalence disorders, especially in the elderly population. Pioglitazone, a PPAR-γ agonist associated with bone loss and risk of fracture in type 2 diabetes mellitus patients. In this study, ameliorative effect of berberine against pioglitazone-induced bone loss in diabetic rats and possible mechanisms has been explored. Diabetes was induced in male Wistar albino rats by streptozotocin (65 mg/kg, i.v.) after 15min of nicotinamide (230mg/kg, i.p.) administration...

Geroderma osteodysplastica (GO) is a subtype of cutis laxa syndrome characterized by congenital wrinkly skin, a prematurely aged face, extremely short stature, and osteoporosis leading to recurrent fractures. GO exhibits an autosomal recessive inheritance pattern and is caused by loss-of-function mutations in GORAB, which encodes a protein important for Golgi-related transport. Using whole exome sequencing, we identified novel compound heterozygous nonsense mutations in the GORAB in a GO patient. The patient was a 14-year-old Japanese boy...

Water treatment using a magnetic field is an attractive but controversial issue with regard to its effects on human health. This study aimed to investigate the effects of water treatment using a magnetic field on the bone mineral density (BMD), bone mineral content (BMC), bone area (BA), bone resistance (BR), blood gas analysis, blood viscosity, and blood biochemical profile of rats. Forty-eight Wistar rats were divided into 2 groups: control (n = 24) and magnetic water-treated (n = 24). Each of these groups was subdivided into 3 groups to evaluate 3 consumption periods (15, 30, and 45 d)...
