The indications for NSAIDs have not changed since 1993. Cox II selective drug prescribing was within the NICE guidance but a substantial proportion of patients taking other NSAIDs had risk factors for gastrointestinal adverse events. Discussion with the GPs highlighted the difficulties of balancing perceived risk of gastrointestinal adverse events with cardioprotection and further guidance is urgently needed.
Six 8-day-old female calves were treated with a subcutaneous implant of 200 mg testosterone + 20 mg estradiol-17 beta. Thirty-five days following implantation, plasma lipoproteins were compared to those in control calves of the same age. The LDL exhibited a slight change in protein and lipid concentrations and no change in particle size. The effects of steroid therapy on HDL and particularly on the lighter density HDL were characterized by a reduction of densities associated with a decrease in protein content, and by a rise in lipids and an increase in particle size. The changes in HDL composition but not in LDL alterations were consistent with those associated with sexual maturation described previously. Although testosterone is the predominant component of our combined preparation, the effects of our treatment on young female calves is not consistent with the data reported for human lipoproteinemia. The high levels of urinary estradiol in treated calves suggest that these effects result more likely from the aromatization of the injected testosterone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
