Background:Although “disaster-related death” as a category awarded disaster-related compensation includes death not caused by the tragedy itself, the actual definition remains unclear.Methods and Results:In the Kumamoto earthquake 2016, compared with the Great East Japan Earthquake 2011, excessive mental and physical stress and suicide were observed significantly more as causes of disaster-related death.Conclusions:It is essential to give maximum consideration to refugees to support them while in shelters.

Aim: Coronary plaque regression is weak in acute coronary syndrome (ACS) patients with diabetes mellitus (DM). We evaluated whether dual lipid-lowering therapy (DLLT) with ezetimibe and atorvastatin attenuates coronary plaques in ACS patients with DM. Methods: The prospective, randomized controlled, multicenter PRECISE-IVUS (Plaque Regression with Cholesterol Absorption Inhibitor or Synthesis Inhibitor Evaluated by Intravascular Ultrasound) trial assigned 246 patients undergoing percutaneous coronary intervention to DLLT or atorvastatin monotherapy and evaluated IVUS-derived changes in percent atheroma volume (ΔPAV), at baseline and 9-12-month follow-up, in 126 ACS cases, including 25 DM patients. The atorvastatin dose was up-titrated to achieve low-density lipoprotein cholesterol (LDL-C) <70 mg/dL. Results: In DM patients, the monotherapy group (n=13) and the DLLT group (n=12) showed a similar prevalence of coronary risks and baseline lipid profiles. During the study, the change in LDL-C level was similar between DM and non-DM patients. Compared with non-DM patients, DM patients showed weaker regression of ΔPAV by DLLT than those who underwent monotherapy (DM: −2.77±3.47% vs. −0.77±2.51%, P=0.11; non-DM: −2.01±3.36% vs. −0.08±2.66%, P=0.008). The change in LDL-C level was not correlated with ΔPAV in non-DM patients, but there was significant correlation between the change in LDL-C level and ΔPAV in DM patients (r=0.52, P=0.008). Conclusions: ACS patients with DM showed weaker coronary plaque regression than their counterparts. A significant correlation between the change in LDL-C level and ΔPAV in DM patients suggested that more intensive lipid-lowering therapy is required in ACS patients with DM.

Background:Direct-activated factor X (FXa) plays an important role in thrombosis and is also involved in inflammation via the protease-activated receptor (PAR)-1 and PAR-2 pathway. We hypothesized that rivaroxaban protects against cardiac remodeling after myocardial infarction (MI).Methods and Results:MI was induced in wild-type mice by permanent ligation of the left anterior descending coronary artery. At day 1 after MI, mice were randomly assigned to the rivaroxaban and vehicle groups. Mice in the rivaroxaban group were provided with a regular chow diet plus rivaroxaban. We evaluated cardiac function by echocardiography, pathology, expression of mRNA and protein at day 7 after MI. Rivaroxaban significantly improved cardiac systolic function, decreased infarct size and cardiac mass compared with the vehicle. Rivaroxaban also downregulated the mRNA expression levels of tumor necrosis factor-α, transforming growth factor-β, PAR-1 and PAR-2 in the infarcted area, and both A-type and B-type natriuretic peptides in the non-infarcted area compared with the vehicle. Furthermore, rivaroxaban attenuated cardiomyocyte hypertrophy and the phosphorylation of extracellular signal-regulated kinase in the non-infarcted area compared with the vehicle.Conclusions:Rivaroxaban protected against cardiac dysfunction in MI model mice. Reduction of PAR-1, PAR-2 and proinflammatory cytokines in the infarcted area may be involved in its cardioprotective effects.

Aims: Royal jelly, a creamy substance secreted by honeybees, has been reported to have beneficial effects against dyslipidemia and metabolic syndrome. However, the effects of royal jelly on atherogenesis remain unknown. Hence, we prospectively evaluated whether royal jelly augments vascular endothelial function, which can reflect early atherogenesis, in healthy volunteers. Methods: This was a single-center, double-blind, 1:1 randomized placebo-controlled study conducted from October 2018 to December 2019. A total of 100 healthy volunteers were randomly assigned to receive either royal jelly 690 mg or placebo daily for 4 weeks. The primary endpoint was augmentation in vascular endothelial function as assessed using the change in the reactive hyperemia peripheral arterial tonometry index (RH-PAT) index, and the secondary endpoints were the changes in liver function and lipid profiles between baseline and 4 weeks after enrollment. Results: The mean age of the participants was 35.0±9.3 years in the placebo group and 36.1±9.1 years in the royal jelly groups; 45% and 50% of the placebo and the royal jelly groups, respectively, were male. The percentage relative change in the RH-PAT index was significantly higher in the royal jelly group than in the placebo group (21.4%±53.1% vs. 0.05%±40.9%, P=0.037). The percentage relative changes in alanine aminotransferase and γ-glutamyl transpeptidase were significantly lower in the royal jelly group than in the placebo group (alanine aminotransferase: −6.06%±22.2% vs. 11.6%±46.5%, P=0.02; γ-glutamyl transpeptidase: −3.45%±17.8% vs. 4.62%±19.4%, P=0.045). Lipid profiles were not significantly different between the two groups. Conclusions: Royal jelly might have antiatherogenic property by improving vascular endothelial function. It also augmented liver functions in healthy volunteers.
