Administering large iron doses more than short period of period increases patients’ threat of infections While intravenous iron is critical for maintaining the ongoing health of many dialysis patients, administering large doses over a short period of period increases patients' threat of developing serious attacks, according to a report appearing in an upcoming issue of the Journal of the American Society of Nephrology . Smaller doses given for a longer period of time appears to be much safer. Dialysis sufferers often develop anemia, or low degrees of red blood cells, and must receive intravenous treatments of iron to improve the condition.‘The first rung on the ladder of our study was to check the working memory of a young and older human population and compare the results,’ says Mervin Blair, 1st author and a PhD student in Concordia’s Department of Psychology and an associate at the Centre for Research in Human being Development. ‘In our study, working memory identifies the power of both processing and retaining information.’ Some 60 individuals took part in the analysis: half were typically 23 years old, while the spouse was about 67 years previous. Each participant was asked to execute an operating memory task, which included recalling and processing different pieces of information. ‘Overall, we showed our older participants had reduced working memory space in comparison to our younger participants,’ says Blair.
