The Role of Pharmacists and Pharmacy Education in Point-of-Care Testing.

Point-of-care testing (POCT) is defined as laboratory testing conducted close to the site of patient care. Although performed originally primarily by clinical staff for acute conditions, recent advances in technology have made such testing possible for disease screening and prevention across a wide range of conditions in virtually any setting, and often by individuals with little or no training. With the ongoing evolution in POCT, numerous concerns have arisen about the quality and accuracy of the tests, comparability between multiple tests for the same endpoint, interpretation of test results, and whether and how results should be used for therapeutic decisions and included in a patient's medical record. The pharmacist is well-positioned to manage and interpret POCT performed outside of the usual clinical settings. However, educational and regulatory changes are needed to enable pharmacists to take on this emerging activity effectively.

Free radicals and related reactive species as mediators of tissue injury and disease: implications for Health.

A radical is any molecule that contains one or more unpaired electrons. Radicals are normal products of many metabolic pathways. Some exist in a controlled (caged) form as they perform essential functions. Others exist in a free form and interact with various tissue components. Such interactions can cause both acute and chronic dysfunction, but can also provide essential control of redox regulated signaling pathways. The potential roles of endogenous or xenobiotic-derived free radicals in several human pathologies have stimulated extensive research linking the toxicity of numerous xenobiotics and disease processes to a free radical mechanism. In recent years, improvements in analytical methodologies, as well as the realization that subtle effects induced by free radicals and oxidants are important in modulating cellular signaling, have greatly improved our understanding of the roles of these reactive species in toxic mechanisms and disease processes. However, because free radical-mediated changes are pervasive, and a consequence as well as a cause of injury, whether such species are a major cause of tissue injury and human disease remains unclear. This concern is supported by the fact that the bulk of antioxidant defenses are enzymatic and the findings of numerous studies showing that exogenously administered small molecule antioxidants are unable to affect the course of most toxicities and diseases purported to have a free radical mechanism. This review discusses cellular sources of various radical species and their reactions with vital cellular constituents, and provides examples of selected disease processes that may have a free radical component.

University-based continuing education for pharmacists.

University-based continuing education (CE) fulfills an important role to support the professional development of pharmacists, advance the practice of pharmacy, and contribute to societal needs for research and healthcare services. Opportunities for pharmacists to engage in new models of patient care are numerous worldwide, particularly as pharmacists' scope of practice has expanded. Approaches to CE have changed to address the changing needs of pharmacists and now include a variety of approaches to support development of knowledge and skills. There is emphasis on the learning process as well as the knowledge, with the introduction of the concept of continuing professional development (CPD).As institutions of research and education, universities are uniquely positioned to bridge the gap between academic and practice environments, providing opportunities for translation of knowledge to practice. The Faculty of Pharmacy and Pharmaceutical Sciences at the University of Alberta is a provider of CE in Alberta, Canada, where an expanded scope of pharmacy practice includes prescribing, administering injections, accessing electronic patient records, and ordering laboratory tests. In this paper, the Faculty offers views about future directions for CE, including the integration of CE with core faculty activities, expanding the audience for CE, areas of focus for learning, and partnerships. Finally, we hope to ignite dialogue with others in the profession about the role and function of university-based CE.

Advancing pharmacist scholarship and research within academic pharmacy.

An appropriate balance between teaching, scholarship, and service is important for a faculty member to have a satisfying and successful career. The relative emphasis on each area normally changes during the course of a career. Although some level of scholarly output is an ongoing and fundamental expectation of all faculty members, this activity is too often given low priority, particularly among faculty members in practice areas who may have a minimal background in research and large demands on their time for teaching and clinical service. Addressing this issue requires establishing a shared commitment between administrators and faculty members, as well as identifying or developing education programs that will ensure research competence for practice faculty members. This paper provides insights into the role that scholarship and research should have for all pharmacy faculty members and provides suggestions for how to better advance this critical component within academic pharmacy.

Cooperation in pharmacy education in Canada and the United States.

Although the education of student pharmacists and the practice of pharmacy in Canada have many similarities with that in the United States, there also are differences. The planning of curricula in pharmacy education is of particular importance to the advancement of pharmacy in Canada because of significant changes in the scope of practice in several provinces, and in how community pharmacy is reimbursed for the services it can, or should, provide. Greater dialog between Canadian and American pharmacists has the potential not only to impact practice on both sides of the border but also to improve collaborations among Canadian and American pharmacy educators. This article provides background information and some suggestions on how to build partnerships in pharmacy education between Canada and the United States. Consortia-like arrangements have some particular promise, as does engaging border-states and provinces in regional meetings and other activities. By working together, Canadian and US pharmacy educators have the opportunity to implement the best of what each has to offer and to devise new and better ways to educate future and existing pharmacists.

Lipocalin-2: pro- or anti-apoptotic?

Survival and apoptosis signaling pathways are altered concomitantly in response to numerous endogenous and exogenous stressors. The lipocalin family of small soluble proteins has been implicated in modulating apoptosis. However, the overall effect of these proteins has been variable, showing both pro- and anti-apoptotic activities. The goal of this minireview is to summarize the studies on lipocalins and apoptosis and consider what roles lipocalin-2 may play in cell death and survival.

Factors influencing the pharmacy faculty workforce.

In 2005, the Council of Faculties and the Council of Deans within the American Association of Colleges of Pharmacy (AACP) formed a task force to review the status of the pharmacy faculty workforce and to identify factors that may influence the supply of and demand for pharmacy faculty members. This manuscript summarizes the Task Force on Faculty Workforce's findings and describes specific strategies needed to address the various issues facing the academy. Based on Task Force predictions, the academy will need approximately 1200 new faculty members over the next 10 years due to the creation of new pharmacy programs, the expansion of existing programs, faculty retirements, and recurring vacant faculty positions.

Thioredoxin-related mechanisms in hyperoxic lung injury in mice.

Reduction of glutathione disulfide (GSSG) to glutathione (GSH) by glutathione reductase (GR) enhances the efficiency of GSH-dependent antioxidant activities. However, GR-deficient (a1Neu) mice are less susceptible to acute lung injury from continuous exposure to > 95% O(2) (96 h: 6.9 +/- 0.1 g right lung/kg body versus room air 3.6 +/- 0.3) than are C3H/HeN control mice (10.6 +/- 1.3 versus 4.2 +/- 0.3, P < 0.001). a1Neu mice have greater hepatic thioredoxin (Trx)1 and Trx2 levels than do C3H/HeN mice, suggesting compensation for the absence of GR. a1Neu mice exposed to hyperoxia for 96 hours showed lower levels of inflammatory infiltrates in lungs than did similarly exposed C3H/HeN mice. Pretreatment with aurothioglucose (ATG), a thioredoxin reductase (TrxR) inhibitor, exacerbated the effects of hyperoxia on lung injury in a1Neu mice (11.6 +/- 0.8, P < 0.001), but attenuated hyperoxic lung edema and inflammation in C3H/HeN mice (6.3 +/- 0.4, P < 0.001). No consistent alterations were observed in lung GSH contents or liver GSH or GSSG levels after ATG pretreatment. The data suggest that modulation of Trx/TrxR systems might provide therapeutically useful alterations of cellular resistance to oxidant stresses. The protective effects of ATG against hyperoxic lung injury could prove to be particularly useful therapeutically.
