OBJECTIVE To study the relation between muscle force, bone mass, and metabolic control in patients with glycogen storage disease type (GSD 1). STUDY DESIGN Distal radius bone mass and density were evaluated in 19 patients with GSD 1 (15 GSD 1a, 4 GSD 1b) by means of peripheral quantitative computed tomography. Grip force was quantified with a dynamometer. RESULTS Height, weight, bone mass, ...

Osteocytes, former osteoblasts buried within bone, are thought to orchestrate skeletal adaptation to mechanical stimuli. However, it remains unknown whether hormones control skeletal homeostasis through actions on osteocytes. Parathyroid hormone (PTH) stimulates bone remodeling and may cause bone loss or bone gain depending on the balance between bone resorption and formation. Herein, we demons...

Osteoporosis as a worldwide problem is discussed in the present review and the question of improving peak bone mass to reduce the risk of osteoporosis and osteoporotic fracture is addressed. The available evidence points to pre-puberty and puberty as the most opportune periods for intervention, but the potential for achievable increments in bone mass is shown to be small compared with the overw...

Amylin is a member of the calcitonin family of hormones cosecreted with insulin by pancreatic beta cells. Cell culture assays suggest that amylin could affect bone formation and bone resorption, this latter function after its binding to the calcitonin receptor (CALCR). Here we show that Amylin inactivation leads to a low bone mass due to an increase in bone resorption, whereas bone formation is...

In recent years, there has been growing concern about the occurrence of metabolic syndrome (MetS) at an early age and its effects on bone mass in adolescents. Adolescence is considered a critical period for bone mass gain. Impaired bone acquisition during this phase can lead to "suboptimal" peak bone mass and increase the risk of osteopenia/osteoporosis and fractures in old age. The objective o...
