The objective of our study was to examine delays between onset of symptoms and treatment for malignant spinal cord compression （MSCC） and to investigate outcomes of neurological function. We performed a retrospective study of clinical records for 25 patients who had been diagnosed with MSCC at a regional center hospital. Thirteen patients had a history of malignancy at the onset of MSCC and 12 patients had no history. For most patients, pain was the first symptom of MSCC. Pain preceded neurologic symptoms by approximately 2 months. The median delays from onset of symptoms of MSCC to treatment were 49 days for all patients, 79 days for those without a history of malignancy and 41.5 days for those with a history of malignancy. It took 39 days from onset to consultation at the hospital, 7 days from consultation to diagnosis and 11 days from diagnosis to treatment. Neurological status was not exacerbated in 8 of 9 patients who had no other neurologic dysfunction at the time of treatment, while only 4 of 10 patients who had deterioration of motor or sensory function at the time of treatment showed improvement in neurological status. In conclusion, there were many delays in all processes from onset to treatment for MSCC and these delays resulted in poor outcome of neurological function.

The vascular endothelial function is impaired in the very early stage of atherosclerosis in diabetic patients. The goal of this study was to identify the mechanism underlying the improvement in vascular endothelial function by sitagliptin in type 2 diabetes mellitus patients. This study was an open-labeled prospective observational single arm trial. Forty patients were treated with 50 mg of sitagliptin once daily for 12-weeks. The flow-mediated dilation (FMD) and plasma adiponectin were measured at baseline and 12 weeks after initiating treatment. The %FMD was significantly increased after treatment (4.13 +/- 1.59 vs 5.12 +/- 1.55, P < 0.001), whereas the nitroglycerin-mediated dilation (NMD) did not change. The plasma adiponectin levels significantly increased (13.0 +/- 11.3 vs 14.3 +/- 12.8, P < 0.001). The changes in the FMD were significantly correlated with those of the plasma adiponectin (r = 0.322, P < 0.05). A multivariate linear regression analysis demonstrated that the improvement in the FMD is associated with the plasma adiponectin (P < 0.05). The treatment of type 2 diabetes mellitus patients with sitagliptin reverses vascular endothelial dysfunction, as evidenced by increase in the FMD, and improvement of the adiponectin levels (UMIN Clinical Trials Registry System as trial ID UMIN000004236).
