The ability to have access to information relevant to patient care is essential within the healthcare environment. To meet the information needs of its workers, healthcare information systems must fulfill a variety of functional requirements. One of these requirements is to define how workers will interact with the system to gain the information they need.(More)
We elicited from medical house staff their preferences for e-mail and alphanumeric pager as communication channels for the delivery of 18 different types of clinical information about their inpatients. For each type, we calculated the proportion of users who preferred delivery by e-mail, pager, both, or neither (usual delivery). For 14/18 (78%) types, more(More)
Although the literature on event monitoring is extensive, it does not cover all issues that we encountered while developing an event monitor at our institution. We had to resolve issues related to event detection, scalability, what topics were suitable for asynchronous decision support, and overlap of efforts of other groups at the institution attempting to(More)
Seven analogues of S-adenosyl-L-methionine were studied as inhibitors or substrates for mammalian spermidine and spermine synthases. One of these, S-(5'-deoxy-5'-adenosyl)-(+/-)-1-methyl-3-(methylthio)propylamine (5), showed a unique spectrum of activities on the polyamine biosynthesis enzymes. It was an inhibitor of S-adenosyl-L-methionine decarboxylase(More)
Eight adenosine analogs, 3-deaza-adenosine (DZA), 3-deaza-(+/-)aristeromycin (DZAri), 2',3'-dideoxy-adenosine (ddAdo), 2',3'-dideoxy-3-deaza-adenosine (ddDZA), 2',3'-dideoxy-3-deaza-(+/-)aristeromycin (ddDZAri), 3-deaza-5'-(+/-)noraristeromycin (DZNAri), 3-deaza-neplanocin A (DZNep), and neplanocin A (NepA), were tested as inhibitors of human placenta(More)
We developed a clinical event monitor that is currently deployed in an inpatient setting. We selected CLIPS as the basis for its KB and inference engine. This paper describes the considerations that went into that decision, how we represented drug and laboratory knowledge in CLIPSs, and how we extended CLIPS to deal with temporal inferences. We also review(More)
Altered calcium homeostasis may play a central role in the liver injury produced by some toxicants. Therefore, the dose and time dependent effects of TCDD on calcium distribution in whole homogenate and subcellular fractions of liver were examined. Groups of female rats were treated with 40 micrograms TCDD/kg for 1, 2 or 3 days. Animals treated with TCDD(More)
Published reports regarding the stability of morphine are at variance, especially in syringes used in patient-controlled analgesia (PCA) devices. In addition to the effects of container type and vehicle, reasons for this variation include the effect of excipients temperature and light during storage. Furthermore, the literature varies regarding the(More)
