Context: Established bone turnover markers do not reflect fracture risk in idiopathic male and premenopausal osteoporosis the role of microRNAs (miRNAs) these patients is currently unclear. miRNAs are a class small non-coding RNAs that regulate gene expression tissue homeostasis. They considered new endocrine regulators with promising potential as biomarkers. Objective: Evaluation circulating miRNA signatures female subjects postmenopausal osteoporotic low-traumatic fractures. Design,...

ABSTRACT Laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are common effective methods to treat severe obesity, but these procedures can adversely influence bone metabolism areal mineral density (aBMD). This was a prospective 24-month single-center interventional two-arm study in 220 women similarly aged men (median age 40.7 years) with body mass index (BMI) >38 kg/m2 after RYGB SG procedures. Patients were randomized into: 1) an intervention group receiving:...

Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by periarticular bone loss and new formation. Current data regarding systemic mineral density (BMD) in PsA are conflicting. The aim of this study was to evaluate microstructure volumetric BMD (vBMD) patients with psoriasis. We performed HR-pQCT scans at the ultradistal radius 50 patients, 30 psoriasis 70 healthy, age- sex-related controls assessing trabecular volume (BV/TV), number (Tb.N), inhomogeneity network,...

The assessment of bone quality and the prediction fracture risk in idiopathic osteoporosis (IOP) are complex prospects as mineral density (BMD) turnover markers (BTM) do not indicate fracture-risk. MicroRNAs (miRNAs) promising new biomarkers for diseases, but current understanding biological information contained variability miRNAs is limited. Here, we investigated association between serum-levels 19 miRNA to microstructure histomorphometry based upon biopsies µCT (9.3 μm) scans from 36...

Abstract During teriparatide (TPTD) treatment, high levels of bone formation are accompanied by an increase in resorption. The aim this work was to test if coadministration raloxifene (RAL) or alendronate (ALN) following 9 months ongoing TPTD therapy would reopen the anabolic window, thereby exerting additional benefit on mineral density (BMD). Postmenopausal women (n = 125) with severe osteoporosis treatment for were randomized into three open-label groups a further months: ALN (70 mg/week)...

Abstract Nine month teriparatide (TPTD) monotherapy followed by co-administration of raloxifene (RAL) or alendronate (ALN) for another nine 9 months resulted in incremental bone mineral density (BMD) increase. The aim this study was to investigate the effects continued antiresorptive treatments 12 extension phase. Postmenopausal women (n = 125) with severe osteoporosis on ongoing TPTD treatment were randomized into three open-label groups months: ALN (70 mg/week, n 41), RAL (60 mg/d, 37)...

Fragility fractures are a frequent and costly event. In Austria, 92,835 fragility occurred in patients aged ≥ 50 years 2018, accruing direct costs of > 157 million €. Due to demographic aging, the number their associated expected increase even further.Fragility frequently with long hospital stays, loss independence, increased need for care elderly, consequences often leading premature death.

Abstract Male idiopathic osteoporosis (MIO) is a metabolic bone disease that characterized by low mass, microstructural alterations, and increased fracture risk in otherwise healthy men. Although the detailed pathophysiology of MIO has yet to be clarified, evidence increasingly suggests an osteoblastic defect as underlying cause. In this study we tested hypothesis expression profile certain or osteoblast-related genes (ie, WNT10B, RUNX2, Osterix, Osteocalcin, SOST, RANKL, OPG) different...

Liver cirrhosis leads to bone loss. To date, information on quality (three-dimensional microarchitecture) and, thus, strength is scarce. We observed decreased at both assessed sites, independent of disease severity. Therefore, all patients should undergo early-stage screening for osteoporosis. Recent studies found low mineral density in cirrhosis, but data microstructure are This study weight-bearing and non-weight-bearing bones with healthy controls. The primary objective was evaluate...
