This study looked at current use of thromboprophylaxis for routine total hip replacement surgery among British orthopaedic surgeons. Of those who replied to a postal survey, 85% use chemical prophylaxis, 15% used mechanical prophylaxis and only 1% use no prophylaxis. This showed a significant increase in the number of surgeons using chemical prophylaxis,(More)
In many small animals there are distinct differences in fiber-type composition among limb muscles, and these differences typically correspond to marked disparities in the oxidative capacities. However, whether there are similar differences in the oxidative capacity among leg muscles in humans is less clear. The purpose of this study was to compare the rate(More)
Reductions in fibrinolytic potential occur with both aging and physical inactivity and are associated with an increased cardiovascular disease risk. Plasmin, the enzyme responsible for the enzymatic degradation of fibrin clots, is activated by tissue plasminogen activator (tPA), while plasminogen activator inhibitor-1 (PAI-1) inhibits its activation.(More)
There is increasing debate about the role of calcium and vitamin D supplementation in the prevention of falls and fractures, with studies raising uncertainty about efficacy and concern about the potential risk of cardiovascular disease. An editorial on the appropriate use of calcium and vitamin D supplementation is therefore timely (pp. 576– 580). The(More)
The scientific method uncovers information from the natural world in small increments. This spurs the design of models to explain how the pieces fit together and to identify future targets of research. This is especially the case in psychology, where visualizing concepts is an advantageous practice. One all too common criticism of cognitive and behavioral(More)
