[source] Prostate cancer treatment options (observation versus prostatectomy) , the available evidenceINTERNATIONAL JOURNAL OF UROLOGICAL NURSING, Issue 3 2007Josephine Hegarty Abstract Advanced screening programmes have led to an increased incidence of prostate cancer worldwide. Prostate Cancer is currently the most common site of male cancers worldwide; accounting for 21% of all male cancers in Ireland. This article presents an in-depth review of the available evidence (January 1997 to April 2007), which directly compares outcomes (in terms of urinary function, bowel function, sexual function, quality-of-life (QOL) outcomes and survival statistics) post radical prostatectomy versus a conservative watch-and-wait approach for the treatment of clinically localized prostate cancer. The aim of this paper is to equip health-care professionals with the best available research evidence. Best research evidence is a component of evidence-based practice, which is very much ,in vogue' in health care today. The authors recommend that practitioners utilize this, the available evidence in combination with their clinical expertise and their patients' opinions in order to assist these patients' to make wise and informed treatment decisions. As this paper will demonstrate, the treatment chosen can have important implications in terms of patient outcomes. Therefore, making an informed decision early on can prevent any regret at a later stage. Overall this review of the literature revealed significant disparity in terms of which treatment option is more favourable. Patients overall are faced with a difficult dilemma when making this treatment decision , to live longer at the expense of potential erectile dysfunction and possible urinary incontinence or to live for a potentially shorter time without these adverse consequences.

[source] MagA is sufficient for producing magnetic nanoparticles in mammalian cells, making it an MRI reporterMAGNETIC RESONANCE IN MEDICINE, Issue 6 2008Omar Zurkiya Abstract Magnetic resonance imaging (MRI) is routinely used to obtain anatomical images that have greatly advanced biomedical research and clinical health care today, but the full potential of MRI in providing functional, physiological, and molecular information is only beginning to emerge. In this work, we sought to provide a gene expression marker for MRI based on bacterial magnetosomes, tiny magnets produced by naturally occurring magnetotactic bacteria. Specifically, magA, a gene in magnetotactic bacteria known to be involved with iron transport, is expressed in a commonly used human cell line, 293FT, resulting in the production of magnetic, iron-oxide nanoparticles by these cells and leading to increased transverse relaxivity. MRI shows that these particles can be formed in vivo utilizing endogenous iron and can be used to visualize cells positive for magA. These results demonstrate that magA alone is sufficient to produce magnetic nanoparticles and that it is an appropriate candidate for an MRI reporter gene.

Blake Knowledge utilization is a field crossing many sectors, from agriculture, since the 1920s, to health care today. Evaluators have made long-standing contributions to understanding knowledge utilization. Different models or ways to think about knowledge utilization have evolved to reflect different perspectives, contexts, and stages of the process, from knowledge creation to the use of effectiveness results in policymaking. The rich interdisciplinary history of this field challenges evaluators to interrogate what knowledge (really) means within a policy or program,whether knowledge is being used more symbolically, rhetorically, or tactically, for example. Differences in program or policy effectiveness across different program sites might result from different types of knowledge use in those sites. © Wiley Periodicals, Inc., and the American Evaluation Association.
