IntroductionThe prognostic value of D-dimer (DD) in sepsis remains controversial. This study aimed to investigate the performance of DD for predicting sepsis mortality in the hospital and for identifying its potential correlates.Materials and methodsThe clinical and laboratory data of adult sepsis patients were extracted from the Medical Information Mart for Intensive Care III (MIMIC III, v1.4) database using the structured query language (SQL). The database contains critical illness admitted to the intensive care unit at Beth Israel Deaconess Medical Center between June 2001 and October 2012. The association between DD and mortality was investigated with receiver operating characteristic (ROC) curve, restricted cubic spline and logistic regression analysis. Subgroup analysis was also used for identifying DD correlates.ResultsThe study population consisted of 358 sepsis patients. Those who died during hospital stay (N = 160) had significantly higher DD values than those who survived (N = 198). The area under the ROC curve (AUC) of DD was 0.59 (P < 0.010). In subgroup analysis, white blood cell (WBC) count > 18 x10⁹/L and vasopressor therapy significantly decreased DD diagnostic performance. Categorical DD value was independently associated with hospital mortality after sequential organ failure score (SOFA) and blood lactate adjustment. Restricted cubic spline analysis revealed a U-shape relationship between DD and in-hospital mortality.DiscussionWe conclude that the accuracy of DD for predicting in-hospital sepsis mortality depends on WBC count and vasopressor therapy. Both low and extremely elevated DD values are associated with higher risk of death.  相似文献

The Impact of Centers and Institutes on Faculty Life: Findings from a Study of Life Sciences Faculty at Research-Intensive Universities’ Medical Schools     

Sarah A. Bunton  William T. Mallon 《Innovative Higher Education》2007,32(2):93-103

This article reports on the impact of organized research centers on professional effort, productivity, and perceptions of work satisfaction for life sciences faculty members at research intensive universities’ medical schools in the U.S. Results indicate that senior center-affiliated faculty members taught less but worked more total hours than peers not affiliated with centers. Senior affiliated faculty members were more productive than their non-affiliated peers and were more likely to be principal investigators on externally funded grants. Center-affiliated faculty members were more likely to be dissatisfied with their mix of activities and workload but more likely to be satisfied with job security and autonomy. Implications beyond this context are suggested. Sarah A. Bunton is a Senior Research Associate at the Association of American Medical Colleges in Washington DC. She received her B.A. from the University of Chicago, her M.A. from the University of Minnesota, and her Ph.D. in higher educational policy also from the University of Minnesota. Her research interests include postsecondary faculty work life and satisfaction, higher education organization, and student development. William T. Mallon is Assistant Vice President and Director of Organization and Management Studies at the Association of American Medical Colleges. Dr. Mallon received his B.A. and M.A. from the University of Richmond and his M.Ed. and Ed.D. in higher education policy from Harvard University. His research interests focus on the ways in which academic medical centers recruit and retain faculty and administrative leaders and the interorganizational relationships among medical schools, teaching hospitals, and parent universities.  相似文献
