Inter-departmental variation in surgical treatment of proximal femoral fractures : A nationwide observational cohort study

Background and purpose Hip fractures should be treated based on the best available evidence and cost-effectively to optimize the outcome for this large group of frail patients. This study examined nationwide variation in surgical methods used for hip fractures. Methods In this cohort study 46,243 patients ≥65 years with a trochanteric hip fracture (THF) or a femoral neck fracture (FNF) registered

The different strategies in treating displaced femoral neck fractures : mid-term surgical outcome in a register-based cohort of 1,283 patients aged 60-69 years

BACKGROUND AND PURPOSE: In patients around retirement age controversy exists as to whether to treat displaced femoral neck fracture (dFNF) with internal fixation (IF) or arthroplasty. An arthroplasty in this age group may need revision due to a long expected remaining lifetime. IF carries a higher risk of early failure but a maintained native hip if healing occurs. We aimed to determine the cumula

Serum copper, zinc and copper/zinc ratio in relation to survival after breast cancer diagnosis: A prospective multicenter cohort study

BackgroundThe essential trace elements copper and zinc, and their ratio (copper/zinc), are important for maintaining redox homeostasis. Previous studies suggest that these elements may impact breast cancer survival. However, no epidemiological study has so far been conducted on the potential association between copper and copper/zinc levels and survival after breast cancer diagnosis. In this study

The Role of Scientific Language Use and Achievement Level in Student Sensemaking

Many science students struggle with using scientific language and making sense of scientific phenomena. Thus, there is an increased interest in science education research and public policy with regard to understanding and promoting scientific language use and sensemaking in science classrooms. However, there is a lack of comparative studies on how upper-secondary school students of different achie

Imagining a post-antibiotic era : a cultural analysis of crisis and antibiotic resistance

The study presented in this article is about the role played by imagination when national and international organisations convey the idea of a dystopian crisis involved in the real transition to a postantibiotic era. The present is an era that can be defined as a time when no new antibiotics are discovered or developed, and existing antibiotics simultaneously become less effective since bacteria d

The possible role of the vasopressin system in hematopoiesis

Vasopressin is a pleiotropic hormone that controls body fluid homeostasis. Vasopressin has also been proposed to be involved in erythropoiesis, thrombocyte activity and inflammation. However, whether increasing vasopressin is associated with changes in hematopoietic markers is not known. To evaluate this gap of knowledge we measured the vasopressin marker copeptin and markers of erythropoiesis (er
