Overall, the MMSE had good sensitivity and specificity across all age and educational groups. Optimal cutoff points were lower in the older age groups and those with less education, primarily to preserve specificity. This screening instrument is appropriate for use with the oldest-old.

Introduction: Although the effects of U2 small nuclear RNA auxiliary factor 1 gene (U2AF1) mutations on the outcomes of patients with myelodysplastic syndromes (MDS) have previously been investigated, their prognostic significance remains controversial. We performed a metaanalysis to investigate the impact of U2AF1 mutations on MDS progression. Methods: Two reviewers independently extracted information such as hazard ratios (HRs) and 95% confidential intervals (CIs) for overall survival (OS) and leukemia-free survival (LFS) as well as the number of surviving patients each year after diagnosis from the included studies. Results: Thirteen studies with a total of 3038 patients were included. The summary odds ratio (OR) for U2AF1 mutations with an OS of 5 years was 0.37, the summary HR for U2AF1 mutations in OS was 1.60, and the summary OR for an OS of 5 years in patients with U2AF1 S34 and U2AF1 Q157 was 3.68. There were no significant differences in leukemia-free survival or hypomethylating therapy response between patients with and without U2AF1 mutations. Conclusion: U2AF1 mutations were associated with poor survival in MDS patients, and patients with U2AF1 Q157 had a worse OS than those with U2AF1 S34 . Our findings suggest that MDS patients with U2AF1 mutations could benefit more from hypomethylation therapy.
