An increase in hip fracture incidence during the recent half-century has been reported worldwide and has been predicted to continue. Recent publications, however, have reported stable or even decreasing hip fracture incidence. No reports evaluate whether these changes in hip fracture incidence are associated with changes in bone mineral density (BMD), if they apply in both urban and rural settings
Background and purpose The number of national arthroplasty registries is increasing. However, the methods of registration, classification, and analysis often differ. Methods We combined data from 3 Nordic knee arthroplasty registers, comparing demographics, methods, and overall results. Primary arthroplasties during the period 1997-2007 were included.

Atrial fibrillation (AF) is a common arrhythmia among patients scheduled for open heart surgery and is associated with increased morbidity and mortality. According to international guidelines, symptomatic and selected asymptomatic patients should be offered concomitant surgical AF ablation in conjunction with valvular or coronary surgery.

Background. Knowledge pertaining to the relationship between migration status and psychosocial job characteristics and long-term illness is not readily available in the international literature. The aim of this study is to analyse the cross-sectional associations between high psychological job demands and low decision latitude (high job strain), work-related social support and long-term illness am
Atlantic salmon accumulate high levels of contaminants such as polychlorinated biphenyls (PCBs) in their lipids during the adult growth phase spent at sea. The lipids are later utilized during migration for swimming and biological adaptations. We hypothesize that migrating salmons' biotransformation processes are affected by the high levels of built-up PCBs compared to salmon that in a pre-migrati
