The purpose of this study was to evaluate the distinct pathogenic mechanisms underlying chronic hypertension in pregnancy and preeclampsia in terms of oxidative stress and vascular reactivity. A total of 17 women with uncomplicated pregnancies, 30 women with preeclampsia and 17 women with chronic hypertension were evaluated. We measured serum derivatives of reactive oxygen metabolites (d-ROMs; marker of oxygen free radicals), flow-mediated vasodilation (FMD; marker of endothelial function) and intima-media thickness in the carotid artery (IMT; marker of atherogenesis) during pregnancy and 1 month after delivery.

A major earthquake measuring 9.0 on the Richter scale struck northeastern Japan at 2:46 pm on 11 March 2011. Several reports have described transient increases in blood pressure after major earthquakes, but the impact of such increases on hemodialysis patients has not been reported. We retrospectively investigated changes in blood pressure and influencing factors in 205 patients (mean age 66.6±13.0 years; male 51.7%; median dialysis vintage 6.0 (2.0–11.0) years) on chronic dialysis at three dialysis centers in the affected area (Fukushima City) for 8 weeks after the earthquake.
