Objective: To analyze the effects of statins on bone mineral density (BMD), in participants from a large population-based cohort.Subjects and methods: We studied 2315 subjects (1422 women and 893 men) from the Camargo Cohort, and analyzed the differences in BMD between statin or non-statin users. We also studied the effect of the type of statin, dose, pharmacokinetic properties, and length of treatment, on BMD.Results: Four hundred...

Background: Pathophysiological calcification in the vasculature is a risk factor for cardiovascular disease (CVD). CVD are among the most common causes of death in patients with chronic kidney disease and crucial for kidney transplantation (RTX) outcomes.Aim: The aim of this study is to identify differences in the pattern and the onset of expression of regulators of calcification (RC) in atherosclerosis (AS) and media sclerosis (MS).<p class="abstext...

Obesity, diabetes, and high fracture risk is linked, but the mechanism is unclear. However, impaired acute adipose tissue inflammation may be a common denominator for these conditions. Impaired adipose tissue inflammation leads to low adipogenesis, insufficient adipose expansion, and signs of diabetes.The aim of this study was to investigate if the low adipogenesis induced by impaired adipose tissue inflammation is coupled to increased osteoblastogenesis...

Osteoprotegerin gene (OPG) is an important candidate gene of osteoporosis. Association of the OPG polymorphisms and bone mineral density (BMD) have been studied by several research groups, however results are not uniform.The aim of this study was to determine if two polymorphisms in the OPG gene influence bone turnover markers and bone mineral density (BMD) in postmenopausal women and elderly men. A total of 135 patients, aged 41–87 years, were incl...

Introduction: Diabetes mellitus may affect bone via bone structure, bone density, and biochemical markers of bone turnover. The aim of this meta-analysis was to examine biochemical markers of bone turnover in diabetics compared to non-diabetics.Methods: A systematic literature search was conducted using Pubmed, Embase, Cinahl, and Svemed+ with the search terms: ‘Diabetes mellitus’, ‘Diabetes mellitus type 1’, ‘Insulin dependent d...

In previous studies, discrepant effects of TSH and thyroid hormones on bone have been reported. While low TSH and high thyroxine (T4) levels increase bone turnover, a recent study suggested a positive association between triiodothyronine (T3) levels and mineral deposition in bone. No data are available on bone architecture and strength in relation to thyroid status.Aim: Using a cross-sectional design, we determined whether bone dens...

Introduction: Bioelectrical impendance analysis (BIA) and dual enargy X-ray absorptiometry (DXA) are two most common methods used for body composition analysis. The aim of this study was to investigate: i) if there is a correlation between body mineral content (BMC) determined by BIA and by DXA for bone mineral content (BMC) and ii) correlation of BMC (BIA) vs bone mineral density (BMD) of L1–L4 spine, dual femur total mean and neck mean.Methods: Tw...

Objective: To assess the relationship between thyrotoxicosis and osteoporotic fractures in men and women.Design: Register-based cohort study in patients with a TSH measurement in the region of Funen 1996–2010. All determinations were done in the same lab serving all hospitals and GP practices. Persons with raised TSH or a history of thyroid/pituitary disease were not included.Results: The study population consisted of 222 138 ...

Background and aims: Low bone formation is the main pathogenic mechanism of osteoporosis in primary biliary cirrhosis (PBC). Sclerostin, an inhibitor of the Wnt pathway, is involved in the regulation of osteoblastogenesis and little is known about its role in the development of bone disease in PBC. Thus, we evaluated the circulating levels of sclerostin and its relationship to bone mass, the parameters of mineral metabolism and liver disease severity.Met...

We have previously shown that female neuronal nitric oxide synthase knockout (nNOS KO) mice have increased trabecular bone volume. However, this study was performed in mice at 10 weeks of age only. To investigate whether the high bone volume is maintained during ageing, we compared 3-month- and 12-month-old wild type (WT) and nNOS KO mice using μCT. The tibias from 8 WT and 8 nNOS KO mice at each age were dissected, fixed for 24 h in buffered formalin, stored in 70% ethan...
