After examining results for 10 different bone fracture sites, advanced age appeared the single best possibility for uniting several different sites, resulting in an empirically based composite fracture risk model.

Several fracture prediction models that combine fractures at different sites into a composite outcome are in current use. However, to the extent individual fracture sites have differing risk factor profiles, model discrimination is impaired.

HIV infection is associated with an almost 3-fold increase in fracture risk compared to that of uninfected age and gender-matched uninfected patients.

HIV patients are also at an almost 9-fold higher risk of hip fracture.

This review describes the most recent data on the effects of glucocorticoids on the Wnt signaling pathway, especially on their antagonists, sclerostin and Dkk-1.

Bone formation is suppressed in glucocorticoid-induced osteoporosis. One of the mechanisms by which glucocorticoids depress bone formation is through their effects on the Wnt/β-catenin signaling pathway, a critical regulator of osteoblastogenesis.

Long-term adherence (five years) to diets that feature normal levels of calcium, low protein and low salt may reduce numbers of stone recurrences,

decrease oxaluria and calcium oxalate relative supersaturation indexes in people with idiopathic hypercalciuria who experience recurrent kidney stones.

Adherence to a low salt, normal calcium level diet for some months can reduce calciuria and oxaluria. However, the other dietary interventions examined did not demonstrate evidence of significant beneficial effects.No studies were found investigating the effect of dietary recommendations on other clinical complications or asymptomatic idiopathic hypercalciuria.

In our study, postmenopausal women who live in rural populations have more poverty, lower values of vitamin D, lower BMD in the lumbar spine and a higher prevalence of vertebral fractures and of osteoporosis.

The higher prevalence of obesity, arterial hypertension and diabetes mellitus observed in these women may be adjuvant factors, all fostered by their socioeconomic state of poverty.

A particular subset of postmenopausal patients with high remodeling and/or low subchondral bone density may benefit from the treatment with bone-acting agents hindering OA progression.

This OA population could be identified with the simultaneous use of subchondral bone dual-energy X-ray absorptiometry and scintigraphy.

The magnitude of the problem of osteoporosis in psoriatic arthritis seems to be mild.

A high prevalence of secondary causes of osteoporosis is observed in HIV-infected patients, and its type and cumulative number determine a lower BMD, after adjusting by age and body mass index.

Eighty-one percent of human immunodeficiency virus (HIV)-infected patients had one or more of seven evaluated causes of secondary osteoporosis, and this rate increases with age. The type and number of causes were associated with a lower bone mineral density (BMD), and with an increased rate of osteopenia/osteoporosis, regardless of age and body mass index.

The incidence of fractures after spinal cord injury is high, with severity and time since spinal cord injury being the main determinants for their development. Fractures were frequently associated with clinical complications.

However, the use of anti-osteoporotic treatment was uncommon.

The results show that patients from all provinces in Spain with severe osteoporosis receiving teriparatide and enrolled in an educational support program had high persistence and satisfaction with the program.

However, no control group was included in these analyses and it is possible that selection bias occurred. It is suggested that patient-based strategies similar to this could be beneficial for all long-term treatments.
