Forty-four clinical episodes of suspected (pancreas) transplant rejection in 17 pancreatic transplantation patients were reviewed retrospectively. The clinical impression of acute graft rejection, chronic rejection, or nonrejection in each episode was correlated with the results of 19 nuclear medicine, 12 ultrasound (US), and 44 magnetic resonance (MR) imaging studies. US was found to be a moderately sensitive (82%) method of detecting graft rejection. US also was effective in identifying intra- and peripancreatic fluid accumulations. Nuclear medicine imaging was also a sensitive technique (86%) and the only modality that provided physiologic information regarding graft perfusion. MR imaging allowed correct prediction of the presence or absence of graft rejection in 39 of 44 cases (sensitivity, 100%; specificity, 76%) and was an effective means of detecting pathologic fluid collections. Nuclear medicine, US, and MR imaging are all believed to be sensitive methods of detecting graft rejection and are complementary adjuncts to the clinical evaluation of pancreatic transplants. 相似文献

In the present study, we examined the exercise preferences of a population-based sample of non-Hodgkin's lymphoma (NHL) survivors. A secondary purpose was to explore the association between various demographic, medical, and exercise behaviour variables and elicited exercise preferences. Using a retrospective survey design, 431 NHL survivors residing in Alberta, Canada completed a mailed questionnaire designed to assess exercise preferences, past exercise behaviour, and various demographic variables. Overall, 77% of participants preferred or maybe preferred to receive exercise counselling at some point after their NHL diagnosis. An overwhelming majority indicated that they would possibly be interested (81%) and able (85%) to participate in an exercise programme designed for NHL survivors. The majority of participants (55%) listed walking as their preferred choice of exercise. Logistic regression analyses indicated that NHL survivors' exercise preferences were influenced by body mass index (BMI), exercise behaviour, and gender. Eliciting exercise preferences from the population in question yields important information for cancer care professionals designing exercise programmes for NHL survivors. Furthermore, tailoring exercise programmes to the preferences of NHL survivors may be one method to potentially enhance exercise adherence in this population both inside and outside of clinical trials. 相似文献
