The increasingly severe shortage of donor hearts has prompted a liberalization of what is considered an acceptable donor heart. The use of marginally acceptable organs has increased in recent years. Although these marginal donors have proved effective, there still remains a tremendous shortage of donors to treat the large number of patients who are candidates for cardiac transplantation. Further use of marginal donors is limited by the requirement to assume immediate and full support of the circulation. New strategies are required to increase donor organ use even further. The authors developed a model of heterotopic abdominal heart transplant (HAHT) to investigate the possibility of using marginal donor hearts to expand the donor pool for cardiac transplantation. The authors' goal was to show that HAHT was technically feasible and could potentially function as auxiliary circulatory support in the setting of low cardiac output. The hemodynamic and metabolic consequences of a HAHT were investigated in a pilot study that provides proof of concept and lays the groundwork for future investigations. 相似文献

The theoretical considerations, operationalization of the constructs, and measurement issues of an ongoing program of research designed to explain ethical practice in nursing are presented. They illustrate the constant give and take among research, the empirical world, and theory building. This case study depicts the iterative and complex process of developing constructs and relationships, based on research findings, that explain moral behavior in nursing practice. 相似文献

A 42-year-old man with a high-grade left internal carotid artery (ICA) stenosis demonstrated on a duplex scan was referred to us. A cerebral arteriogram confirmed a greater than 90% left internal carotid stenosis, but with the unexpected finding of a moderate amount of thrombus in the proximal ICA. He underwent emergent left carotid endarterectomy, but during the operation, only a small amount of thrombus was identified as adherent to the atherosclerotic plaque. he awakened in the operating room with a dense right hemiplegia and aphasia. Immediate reexploration demonstrated a patent endarterectomy site, a distal thromboembolectomy was performed without extraction of thrombus, and urokinase (250,000 Units) was infused into the distal ICA. He reawakened with an unchanged right hemiplegia and aphasia. The patient then underwent an urgent postoperative carotid and cerebral arteriogram that demonstrated an embolus to the middle cerebral artery. he was treated with the superselective infusion of urokinase (500,000 Units), with almost complete resolution of the clot. Over the course of the next 48 hours, the patient made a nearly complete neurologic recovery, and he was discharged from the hospital with only a slight facial droop. At 2 months' follow-up he was completely neurologically healthy. To our knowledge this is the first reported case of urokinase administered in the immediate postoperative period in the angiography suite to treat a thromboembolus complicating a carotid endarterectomy. 相似文献

Education is a driving force in improving the health and welfare of communities globally. Doctoral education of nurses has been identified as a critical factor for provision of leadership in practice, scholarship, research, policy and education. Since the genesis of doctoral education in nursing in the USA in the 1930s, this movement has burgeoned to over 273 doctoral programs in over 30 countries globally. The present article seeks to identify the issues and challenges in nursing doctoral education globally, and those encountered by doctoral program graduates in meeting the challenges of contemporary health care systems. Information was derived from a comprehensive literature review. Electronic databases and the Internet, using the Google search engine, were searched using the key words "doctoral education"; "nursing"; "International Network for Doctoral Education in Nursing"; "global health"; "international research collaboration". Doctoral education has been a critical force in developing nurse leaders in education, management, policy and research domains. An absence of consensus in terminology and of accurate minimum data sets precludes comparison and debate across programs. The complexity and dynamism of contemporary globalized communities render significant challenges in the conduct of doctoral programs. Addressing funding issues and faculty shortages are key issues for doctoral programs, especially those in developing countries, to achieve an identity uniquely their own. These challenges can also afford considerable opportunities for discussion, debate and the formulation of innovative and collaborative solutions to advance nursing knowledge and scholarship. In spite of discrete differences between countries and regions, the similarities in the issues facing the development of doctoral programs internationally are more striking than the differences. The harnessing of a global collective to address these issues will likely serve to not only forge the future viability of doctoral education of nurses but to improve the health and well-being of communities. This paper proposes international collaborative strategies to address a number of the challenges identified. 相似文献

KETEFIAN S., DAI Y.‐T., HANUCHARURNKUL S., MENDES I.A.C. & NORMAN I.J. (2010) Environments for nursing scholarship and journal impact factor in five countries. International Nursing Review 57 , 343–351 Background: Universities worldwide are seeking objective measures for the assessment of their faculties' research products to evaluate them and to attain prestige. Despite concerns, the impact factors (IF) of journals where faculties publish have been adopted. Research objective: The study aims to explore conditions created within five countries as a result of policies requiring or not requiring faculty to publish in high IF journals, and the extent to which these facilitated or hindered the development of nursing science. Design: The design was a multiple case study of Brazil, Taiwan, Thailand (with IF policies, Group A), United Kingdom and the United States (no IF policies, Group B). Key informants from each country were identified to assist in subject recruitment. Methods: A questionnaire was developed for data collection. The study was approved by a human subject review committee. Five faculty members of senior rank from each country participated. All communication occurred electronically. Findings: Groups A and B countries differed on who used the policy and the purposes for which it was used. There were both similarities and differences across the five countries with respect to hurdles, scholar behaviour, publishing locally vs. internationally, views of their science, steps taken to internationalize their journals. Conclusions: In group A countries, Taiwan seemed most successful in developing its scholarship. Group B countries have continued their scientific progress without such policies. IF policies were not necessary motivators of scholarship; factors such as qualified nurse scientists, the resource base in the country, may be critical factors in supporting science development. 相似文献
