BACKGROUND AND AIMS The study investigates one-year mortality risk associated with hip fracture in elderly people, and pre-fracture characteristics and events occurring during the acute phase which may represent significant predictors for acute and long-term mortality. METHODS The study is a prospective cohort study of 252 patients aged 70 and older,(More)
OBJECTIVES To determine whether secondary hyperparathyroidism (HPTH) due to hypovitaminosis D affects bone mineral density (BMD) response to alendronate (ALN) in elderly women with osteoporosis. DESIGN Randomized, controlled trial with 1-year follow-up. SETTING Two osteoporosis centers in northern Italy. PARTICIPANTS Community-dwelling women aged 60(More)
BACKGROUND AND AIMS Few studies have investigated predictors for hospital readmission after hip fracture repair. METHODS In a prospective cohort study we evaluated factors associated with early (within 3 months) and late (between 3-12 months), single and multiple hospital readmission in 236 hip-fractured older adults admitted to an orthopedic unit.(More)
OBJECTIVES To compare the effects on parathyroid hormone (PTH) and 25-hydroxy-vitamin D (25(OH)D) of two dosing regimens of cholecalciferol in women with secondary hyperparathyroidism (sHPTH) and hypovitaminosis D and to investigate variables affecting 25(OH)D response to cholecalciferol. DESIGN Randomized-controlled trial with 6-month follow-up. (More)
OBJECTIVE To evaluate the feasibility and predictors of success of home-based rehabilitation (HBR) in older adults after hip fracture. DESIGN Prospective inception cohort study with 12 months of follow-up. SETTING Acute and subacute care with follow-up in a community setting in Italy. PARTICIPANTS Community-dwelling older adults (N=199) aged 70 years(More)
All hip fracture (HF) subjects are candidates for calcium and vitamin D (CaD) supplementation. Up to 50% of HF older adults present with secondary hyperparathyroidism (HPTH) resulting from hypovitaminosis D on hospital admission. To investigate the patterns and predictors of persistence with CaD supplementation in the elderly after HF, we considered all(More)
OBJECTIVE To evaluate baseline characteristics and in-hospital factors associated with nonadherence with an immediate weight-bearing and early ambulation (IWB-EA) program after hip fracture (HF) surgery. DESIGN Prospective inception cohort study. SETTING Ortho-geriatric unit in an acute care hospital. PARTICIPANTS Older adults (N=469) admitted with an(More)
