Three 18F labeled fluoronitroimidazoles have been prepared as potential in vivo markers of hypoxic cells in tumors, and ischemic areas of the heart and brain. 1-(2-Nitroimidazolyl)-3-[18F]fluoro-2-hydroxypropanol (18F]fluoro-normethoxymisonidazole) 4, 1-(2-[18F]fluoroethyl)-2-nitroimidazole 7, and 1-(2-[18F]-fluoroethyl)-2-methyl-5-nitroimidazole(More)
E-Health involves new forms of patient-physician interaction and poses new ethical challenges and threats to patient privacy. This paper reviews Health On the Net Foundation Code of Conduct (HONcode) accredited e-Health websites that provide online appointment services in the U.S.A for compliance with basic principles of security and privacy. We found that(More)
Retrieval tests have assumed that the abstract is a true surrogate of the entire text. However, the frequency of terms in abstracts has never been compared to that of the articles they represent. Even though many sources are now available in full-text, many still rely on the abstract for retrieval. 1,138 articles with their abstracts were downloaded from(More)
Several initiatives have addressed patient safety by enabling electronic voluntary reporting of adverse events within academic medical centres in urban settings. Such initiatives are lacking in the rural context, and it remains unknown whether the same challenges and solutions apply to rural hospitals. The purpose of this study is to provide insight into(More)
Hypoxic, non-functional, but viable, tissue may exist in heart and brain following an arterial occlusion. Identification of such tissue in vivo is crucial to the development of effective treatment strategies. It has been suggested that certain compounds capable of sensitizing hypoxic tumor cells to killing by x-rays (i.e., misonidazole) might serve as in(More)
BACKGROUND Digital information technology can facilitate informed decision making by individuals regarding their personal health care. The digital divide separates those who do and those who do not have access to or otherwise make use of digital information. To close the digital divide, health care communications research must address a fundamental issue,(More)
BACKGROUND The development of consumer health information applications such as health education websites has motivated the research on consumer health vocabulary (CHV). Term identification is a critical task in vocabulary development. Because of the heterogeneity and ambiguity of consumer expressions, term identification for CHV is more challenging than for(More)
Physicians need better access to information when making patient care decisions. Hospitals should allow electronic data transfers to physician PDAs to improve patient care, and physicians must institute measures to secure the confidentiality of patient information on their PDAs. By explicitly excluding copies from their designated record set, hospitals need(More)
BACKGROUND As telemedicine alters the process of health care and introduces new technology, the extent to which it introduces new errors or allows for the occurrence of familiar errors needs to be examined. TELEMEDICINE'S IMPACT ON PATIENT SAFETY FEATURES OF TRADITIONAL CARE: The accuracy of diagnostic decisions reached via telemedicine can be directly(More)
