We have proposed to the Food and Drug Administration (FDA) that treatment-related increases in total hip bone mineral density (TH BMD) at two years could be a surrogate endpoint for fracture risk reduction in clinical trials. The qualification of a surrogate includes a strong association of the surrogate with the clinical outcome. We compiled a large database of individual patient data (IPD) through the FNIH-ASBMR-SABRE project, and this analysis aimed to assess the relationship between baseline BMD and fracture risk in the placebo groups.

Context: Fracture risk is higher in type 2 diabetes (T2D) for a given bone mineral density (BMD) level. Increased oxidative stress in T2D induces diabetic complications and may affect T2D bone fragility.

Objective: To investigate whether the levels of plasma F2-isoprostanes, a reliable oxidative stress marker, are associated with incident clinical fracture risk in older adults with diabetes.

Background Context: There are a number of risk factors- from biological, psychological, and social domains- for non-specific chronic low back pain (cLBP). Many cLBP treatments target risk factors on the assumption that the targeted factor is not just associated with cLBP but is also a cause (i.e, a causal risk factor).

Article Synopsis
  • Higher FSH levels are linked to bone loss during perimenopause and aging in men, but it was unclear if they independently increase fracture risk.
  • A study analyzed 295 adults from the AGES-Reykjavik cohort to find out if baseline FSH levels could predict hip fractures within 10 years.
  • Results showed that higher FSH levels significantly increased the risk of hip fractures, suggesting FSH might directly affect bone health beyond just being associated with sex hormones.

There is a strong association between total hip bone mineral density (THBMD) changes after 24 mo of treatment and reduced fracture risk. We examined whether changes in THBMD after 12 and 18 mo of treatment are also associated with fracture risk reduction. We used individual patient data (n = 122 235 participants) from 22 randomized, placebo-controlled, double-blind trials of osteoporosis medications.
