Terror Management: The Effects of Mortality Salience on Desire for Money Among Singaporeans

Terror management theory has been used to explain our penchant for materialism. While materialism includes both the desire for products and the desire for money, research has generally examined the former. Consequently, this article aimed to examine the effects of mortality salience on desire for money in Singapore. Study 1 found that mortality salience did not increase self-reported desire for money but increased the size of a drawn coin. Study 2 found that mortality salience did not increase the preferred selling price of a used laptop. Finally, Study 3 found that mortality salience did not increase the willingness to listen to unpleasant sounds in exchange for money. Furthermore, attitudes toward money did not moderate the effects of mortality salience on desire for money. The nonsignificant results could be due to data collection during the coronavirus disease 2019 (COVID-19) pandemic and the use of a Singaporean sample. Future research directions include examining the effects of the pandemic on terror management theory research and examining both the desire for products and the desire for money concurrently as dependent variables

Intraprocedural, intra-arterial CT foot perfusion examination for assessment of endovascular therapy in patients with critical limb ischemia: a prospective pilot study

Background: Current techniques to evaluate computed tomography (CT) foot perfusion in patients with critical limb ischemia use high contrast doses and cannot be used during endovascular procedures. CT perfusion of the foot with intra-arterial contrast injection during endovascular treatment in a hybrid angiography CT suite might solve these problems. Purpose: The main objective of this study was to evaluate whether intra-arterial CT foot perfusion using a hybrid CT angiosystem is feasible during endovascular treatment for critical limb ischemia. Material and Methods: This prospective pilot study investigated intraprocedural, intra-arterial CT perfusion of the foot using a hybrid CT angiosystem in 12 patients before and after endovascular treatment for critical limb ischemia. Time to peak (TTP) and arterial blood flow were measured before and after treatment and compared using a paired t test. Results: All 24 CT perfusion maps could be calculated adequately. The contrast volume used for one perfusion CT scan was 4.8 ml. The mean TTP before treatment was 12.8 seconds (standard deviation [SD] 2.8) and the mean TTP posttreatment was 8.4 seconds (SD 1.7), this difference being statistically significant (p=.001). Tendency toward increased blood flow after treatment, 340 ml/min/100 ml (SD 174) vs 514 ml/min/100 ml (SD 366) was noticed (p=.104). The mean effective radiation dose was 0.145 mSv per scan. Conclusion: Computed tomography perfusion of the foot with low contrast dose intra-arterial contrast injection during endovascular treatment in a hybrid angiography CT suite is a feasible technique. Clinical Impact Intra-arterial CT foot perfusion using a hybrid CT-angiography system is a feasible new technique during endovascular therapy for critical limb ischemia to assess the results of the treament. Future research is necessary in defining endpoints of endovascular treatment and establishing its role in limb salvage prognostication.Radiolog
