25-hydroxyvitamin D levels in the early healing of osteoporotic hip fracture and their relationship with clinical outcome.

Introduction: vitamin D is involved in recovery after an osteoporotic hip fracture (OHF). Previous studies have reported decreased serum vitamin D levels during fracture healing. Objectives: our aim was to evaluate: a) serum 25-hydroxyvitamin D3 (25OHD3) levels in patients with OHF at hospital admission and 8 days post-admission, and b) the relationship between 25OHD levels and clinical outcomes.

Multicentre evaluation of glycated haemoglobin (HbA1c) of Roche Diagnostics in Andalusia.

Background: A Spanish multicentre evaluation of the third generation of Roche Diagnostics immunoturbidimetric inhibition method (TINIA) is presented for quantification of haemoglobin A1c (HbA1c) in whole blood.

Methods: The analytical performance of the TINIA test was evaluated and blood sample results were compared with two other widely used analysers, Bio-Rad Variant II and Adams Arkray HA-8160, based on HPLC.

Results: Within- and between-batch imprecision (coefficients of variation (CVs)) for HbA1c levels of 5, 6, 7 and 8% were 0.
