The purpose of this study is to investigate the association of serum osteoprotegerin (OPG) and the A163G polymorphism in the OPG promoter with peripheral measures of bone mass and with odds ratios for wrist and hip fracture in a case-control study of postmenopausal Danish women. The study included 66 women with lower forearm fracture, 41 women with hip(More)
BACKGROUND AND PURPOSE Hip fractures are associated with high mortality, but the cause of this is still not entirely clear. We investigated the effect of surgical delay, weekends, holidays, and time of day admission on mortality in hip fracture patients. PATIENTS AND METHODS Using data from the Danish National Indicator Project, we identified 38,020(More)
Displaced femoral neck fractures are known to be associated with high rates of mortality. The purpose of the present study is to investigate pre- and postoperative factors which influence this mortality in a series of 1186 consecutive Danish patients presenting to one hospital's orthopaedic department with Garden type 3-4 fractures. Subsequent mortality(More)
OBJECTIVE To determine whether common allelic variation at the vitamin D receptor locus is related to bone mineral density and postmenopausal bone loss. DESIGN Cross sectional and longitudinal population study. SETTING Outpatient clinic in research centre. SUBJECTS 599 healthy women aged 27 to 72 and 125 women with low bone mass aged 55-77 had bone(More)
PURPOSE To evaluate the influence of time of day on the circulating concentrations of 21 hematology parameters. MATERIALS AND METHODS Venous blood samples were obtained under standardized circumstances from 24 healthy young men every third hour through 24 hours, nine time points in total. At each time point, the level of melatonin, iron, transferrin,(More)
PURPOSE To evaluate the influence of time of day on the circulating concentrations of 14 frequently used clinical biochemical parameters in the Bispebjerg study of diurnal variations. MATERIALS AND METHODS Venous blood samples were obtained under controlled environmental, activities and food conditions from 24 healthy young men every third hour through 24(More)
BACKGROUND The web has become a primary information resource about illnesses and treatments for both medical and non-medical users. Standard web search is by far the most common interface to this information. It is therefore of interest to find out how well web search engines work for diagnostic queries and what factors contribute to successes and failures.(More)
OBJECTIVES To evaluate the rate of postoperative complications, length of stay, and 1-year mortality before and after introduction of a comprehensive multidisciplinary fast-track treatment and care program for hip fracture patients (the optimized program). DESIGN Retrospective chart review with historical control. SETTING Orthopedic ward (110 beds) at a(More)
Quantitative ultrasound (QUS) bone measurement is a promising, relatively new technique for the diagnosis of osteoporosis. Unlike to the more established method of bone densitometry [measurement of bone mineral density (BMD) e.g. using dual X-ray absorptiometry (DEXA)], QUS does not use ionizing radiation. It is cheaper, takes up less space and is easier to(More)
BACKGROUND Pancreaticoduodenectomy is the only potentially curative treatment for peripapillary pancreatic tumors. However, postoperative morbidity and mortality are high, and different approaches have been tried to improve results, such as preoperative biliary drainage in patients with jaundice. This meta-analysis investigated the effect on postoperative(More)
