Objective This retrospective study aimed to investigate the association between therapeutic strategies and the development of major cardiac events (MCEs) in intermediate-risk patients by using the the Japanese Assessment of Cardiac Events and Survival Study by Quantitative Gated SPECT (JACCESS) risk model in combination with the stress phase bandwidth (SPBW), an index of left ventricular dyssynchrony. Methods Patients were followed-up for three years to confirm their prognosis. Based on the estimated propensity scores, the patients who underwent revascularization within the first 60 days after SPECT and those who did not were matched 1:1 (n=367 per group). ⋯ The overall incidence of MCE in intermediate-risk patients was not significantly different between the two groups. However, the incidence of MCE in patients with an abnormal SPBW was significantly lower in those who underwent early revascularization (4.8% vs. 11.9%, p=0.0407). Conclusion The combination of the J-ACCESS risk model and the SPBW is thus considered to be an optimal treatment strategy for patients at intermediate risk of MCE, and early revascularization may lead to an improved prognosis in intermediate-risk patients with an abnormal SPBW.

Ovary microcystic stromal tumor (MCST) is an extremely rare subtype of sex cord-stromal neoplasm, and only 57 cases have been reported. We herein report a unique case of ovarian MCST with positive nestin expression in a 39-year-old Chinese woman. ⋯ To our knowledge, no report has described a case of ovarian MCST with positive staining for nestin protein. Our study provides new insights into the tumor biology of ovarian MCST.

Case Reports
Cardiac Sarcoidosis which Occurred four Years after Successful Treatment of Cutaneous Sarcoidosis with Minocycline.
A 67-year-old woman was admitted to our hospital because of a complete right bundle branch block. She had been treated with minocycline for skin sarcoidosis and her symptoms had ameliorated four years previously. ⋯ Immunohistochemical staining for Cutibacterium acnes was positive for granulomas of the skin lesions which had been previously biopsied. One year after starting the administration of steroids, her condition improved.

Objective Mucuna pruriens (MP) is a legume whose seeds contain levodopa (LD), which has potential therapeutic effects against Parkinson's disease (PD). However, further research is needed to thoroughly evaluate its efficacy and safety for treating this condition. In this study, we analyzed the pharmacokinetics of MP grown in Japan and investigated its mechanism of action in PD. ⋯ An analysis of the LD metabolites showed that the 3-O-methyl-dopa/LD metabolic ratio was significantly lower after MP ingestion than after LD/CD ingestion, indicating that MP has a catechol-O-methyl transferase inhibitory effect. Conclusions This is the first report of a pharmacokinetic analysis conducted on actual patients with PD showing that MP significantly prolongs the ON time. The advantages of MP as a treatment for PD have been confirmed: it is inexpensive, as effective as LD, works faster and longer than LD, and does not increase dyskinesia.
