Whom to treat? The contribution of vertebral X-rays to risk-based algorithms for fracture prediction. Results from the European Prospective Osteoporosis Study.

Introduction: Vertebral fracture is a strong risk factor for future spine and hip fractures; yet recent data suggest that only 5-20% of subjects with a spine fracture are identified in primary care. We aimed to develop easily applicable algorithms predicting a high risk of future spine fracture in men and women over 50 years of age.

Methods: Data was analysed from 5,561 men and women aged 50+ years participating in the European Prospective Osteoporosis Study (EPOS).

Back pain, disability, and radiographic vertebral fracture in European women: a prospective study.

Vertebral fractures are associated with back pain and disability. There are, however, few prospective data looking at back pain and disability following identification of radiographic vertebral fracture. The aim of this analysis was to determine the impact of radiographically identified vertebral fracture on the subsequent occurrence of back pain and disability.

Determinants of the size of incident vertebral deformities in European men and women in the sixth to ninth decades of age: the European Prospective Osteoporosis Study (EPOS).

Unlabelled: More severe vertebral fractures have more personal impact. In the European Prospective Osteoporosis Study, more severe vertebral collapse was predictable from prior fracture characteristics. Subjects with bi-concave or crush fractures at baseline had a 2-fold increase in incident fracture size and thus increased risk of a disabling future fracture.

Falls explain between-center differences in the incidence of limb fracture across Europe.

There is important geographic variation in the occurrence of the major osteoporotic fractures across Europe. The aim of this study was to determine whether between-center variation in limb fracture rates across Europe could be explained by variation in the incidence of falls. Men and women, aged 50-79 years, were recruited from population-based registers in 30 European centers.

Incidence of limb fracture across Europe: results from the European Prospective Osteoporosis Study (EPOS).

The aim of this population-based prospective study was to determine the incidence of limb fracture by site and gender in different regions of Europe. Men and women aged 50-79 years were recruited from population registers in 31 European centers. Subjects were invited to attend for an interviewer-administered questionnaire and lateral spinal radiographs.

Incidence of vertebral fracture in europe: results from the European Prospective Osteoporosis Study (EPOS).

Vertebral fracture is one of the major adverse clinical consequences of osteoporosis; however, there are few data concerning the incidence of vertebral fracture in population samples of men and women. The aim of this study was to determine the incidence of vertebral fracture in European men and women. A total of 14,011 men and women aged 50 years and over were recruited from population-based registers in 29 European centers and had an interviewer-administered questionnaire and lateral spinal radiographs performed.

[Clinical value of urinary pyridinium crosslinks as osteoporosis markers: evaluation of a population survey of vertebral osteoporosis].

Background: The diagnostic value of biochemical parameters of bone turnover for the diagnosis of osteoporosis is open to discussion. We investigated whether the determination of crosslinks, bone type I collagen degradation products, correctly identifies osteoporotic subjects.

Patients And Method: In a sample of 370 individuals recruited at random within a population survey of vertebral osteoporosis, urinary concentration of total pyridinoline and desoxypyridinoline were determined by HPLC.

TGFbeta1 and TGFbeta2 mRNA and protein expression in human bone samples.

Transforming growth factor beta is one of the most abundant growth factors stored in bone. It is known as a potent regulator of osteoblast proliferation and differentiation as well as of production extracellular matrix. We established a highly specific RT-PCR in combination with HPLC for detection and quantification of TGFbeta1 and TGFbeta2 mRNA expression in 89 human bone samples.

Analysis of TGFbeta3 gene expression and protein levels in human bone and serum.

Recent data indicate that TGFbeta3, one member of the TGFbeta-isoforms, has an important role in bone remodeling. Up to date little is known about the expression and regulation of TGFbeta3 in man. We established a highly specific ELISA for quantitative measurement of TGFbeta3 in bone and blood samples and a RT-PCR in combination with HPLC for detection and quantification of TGFbeta3 mRNA in 89 human bone samples.

Prevalent vertebral deformity predicts incident hip though not distal forearm fracture: results from the European Prospective Osteoporosis Study.

The presence of a vertebral deformity increases the risk of subsequent spinal deformities. The aim of this analysis was to determine whether the presence of vertebral deformity predicts incident hip and other limb fractures. Six thousand three hundred and forty-four men and 6788 women aged 50 years and over were recruited from population registers in 31 European centers and followed prospectively for a median of 3 years.

Circulating tumor necrosis factor alpha is elevated in male but not in female patients with type II diabetes mellitus.

The cytokine tumor necrosis factor alpha (TNF alpha) was proposed to mediate obesity related insulin resistance upon production in fat cells and to participate in tissue remodelling leading to vascular complications upon being released by macrophages. To assess its putative role in diabetes we determined plasma levels of TNF alpha in 105 adult humans. Male nondiabetic subjects had significantly lower TNF alpha levels than female controls (4.
