Bone mineral density distribution in early osteoporotic bone

Abdulghani Saba , Santos Luis , Vidal Bruno , Cascao Rita , Fonseca Joao

Osteoporosis (OP) is characterised by low bone mass and microarchitectural deterioration of the bone tissue, leading to enhanced bone fragility and increased fracture risk. OP causes an imbalance in the cellular remodelling process thus inducing changes in the bone’s mineral and organic phases that are responsible for its strength and stiffness. The purpose of this study is to investigate the early effects of OP progression on the arrangement of bone tissue mineral phase ...

Arthritis induces early bone structural degradation and mechanical weakness

Vidal Bruno , Cascao Rita , Finnila Mikko , Lopes Ines , Saarakkala Simo , Canhao Helena , Fonseca Joao

Background: We have previously found in the chronic SKG mouse model of arthritis that long standing (5 and 8 months) inflammation directly leads to high collagen bone turnover, disorganization of the collagen network, disturbed bone microstructure and ultimately declining in bone biomechanical properties. Our main goal was to study the effects of the inflammatory process on the microarchitecture and mechanical properties of bone in the early stages of arthritis development.</p...

Introduction: Osteoporosis is frequently associated with renal disease, namely the bone metabolism disturbances caused by secondary hyperparathyroidism of chronic kidney disease (CKD). The increased risk of fragility fractures is well demonstrated in patients with end-stage renal disease (ESRD). There is recent evidence that bone pathological changes start early in the course of CKD. Our aim is to evaluate whether chronic renal disease, before ESRD, is associated with bone fra...
