This study has found that though a decline exists in the national HIV prevalence and the HIV prevalence a...
Objectives to describe the secular trend and seasonal variation in the incidence of hip fracture (HF) over 12 years (2003-2014) in Catalonia, the community with the highest incidence of HF in Spain. Methods data about age, gender, type of fracture and month of hospitalisation among patients aged 65 years and older discharged with a diagnosis of HF were collected. Crude and age-standardised an...

Methods: Bone mineral density was evaluated by single-photon absorptiometr...
