OBJECTIVE: The aim of this study was to examine the concurrent validity of a newly developed computerized memory diagnostic system (MDS) with the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K). METHODS: Subtests of the MDS and CERAD-K, including the auditory-verbal, visuo-spatial, and working memory tests, were administered to 43 adults aged 60 to 74 years. We calculated the correlations between the subtest scores of the MDS and CERAD-K to examine the concurrent validity of the MDS. RESULTS: We found significant correlations between the subtest scores in the verbal-auditory memory, including immediate recall, delayed recall, and delayed recognition. The working memory subtest scores between the MDS and CERAD-K also showed a significant positive correlation. CONCLUSION: We verified the concurrent validity of the memory subtests in the MDS for the elderly. The results of the present study suggest that the MDS could be a valuable tool for an efficient and valid assessment of memory function.

A new blood bank system was established in our trauma bay, which allowed immediate utilization of uncross-matched type O packed red blood cells (UORBCs). We investigated the efficacy of UORBC compared to that of the ABO type-specific packed red blood cells (ABO RBCs) from before the bank was installed. From March 2016 to February 2017, data from trauma patients who received UORBCs in the trauma bay were compared with those of trauma patients who received ABO RBCs from January 2013 to December 2015. Propensity matching was used to overcome retrospective bias. The primary outcome was 24-hour mortality, while the secondary outcomes were in-hospital mortality and intensive care unit (ICU) length of stay (LOS). Data from 252 patients were reviewed and UORBCs were administered to 64 patients. The time to transfusion from emergency room admission was shorter in the UORBC group (11 [7–16] minutes vs. 44 [29–72] minutes, P < 0.001). After propensity matching, 47 patients were included in each group. The 24-hour mortality (4 [8.5%] vs. 9 [13.8%], P = 0.135), in-hospital mortality (14 [29.8%] vs. 18 [38.3%], P = 0.384), and ICU LOS (9 [4–19] days vs. 5 [0–19] days, P = 0.155) did not differ significantly between groups. The utilization of UORBCs resulted in a faster transfusion but did not significantly improve the clinical outcomes in traumatic shock patients in this study. However, the tendency for lower mortality in the UORBC group suggested the need for a large study.
