Summary objectives:The aim of this study was to determine the effects of pain and fatigue on daily life activities of systemic lupus erythematosus (SLE) patients.
Methods:The study sample included 74 SLE patients who presented to outpatient departments of a university hospital and two local hospitals between 30.9.2009 and 15.5.2010. Data was collected using the Fatigue Severity Scale, Katz's Activity's Daily Living Index, Lawton and Brody's Instrumental Activities of Daily Living, and the McGill Pain Questionnaire.
results:The mean scores were 6.0 (fatigue) on the Fatigue Severity Scale, 18.0 (independent) on the Daily Life Activities Index, 24.0 (independent) on the Instrumental Daily Life Activities Index, and 1.56 (discomforting) on the McGill Pain Scale for pain felt at the moment of questioning. A low-level negative relationship was observed between the scores on the Fatigue Severity Scale and the Daily Life Activities Index (p<0.05, r=-0.298), and between Fatigue and Instrumental Daily Life Activities scores (p<0.05, r=-0.354). A medium-level positive relationship was observed between the scores on the Fatigue Severity Scale and the McGill Pain Scale (p<0.05, r=0.478).
Conclusion:This study determined that pain and fatigue affected the daily lives of SLE patients. The study should be repeated on a larger sample.
A simulation model (BGRAF) capable of representing the emergency egress behavior of people in fires was developed at the University of Michigan. The software, written in Fortran, can be used to test different hypothesis about human behavior in fires. The cognitive effects of the physical environment were also incorporated into the decision making process simulated in this model. The graphic output animates the actions of the simulated people on a building plan on the screen. Tabular output is also provided. A building data base created by CAEADS computer-aided design software developed at the University of Michigan with partial funding from the U.S. Army Corps of Engineers is accessed by BGRAF during the input phase. The use of a CAD data base to model the physical environment was critical in creating an accurate model, since the actions of the simulated persons hinged upon the limitations of the physical environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
