Background: We established a community-based cohort study to assess the long-term impact of the Great East Japan Earthquake on disaster victims and gene-environment interactions on the incidence of major diseases, such as cancer and cardiovascular diseases.Methods: We asked participants to join our cohort in the health check-up settings and assessment center based settings. Inclusion criteria were aged 20 years or over and living in Miyagi or Iwate Prefecture. We obtained information on lifestyle, effect of disaster, blood, and urine information (Type 1 survey), and some detailed measurements (Type 2 survey), such as carotid echography and calcaneal ultrasound bone mineral density. All participants agreed to measure genome information and to distribute their information widely.Results: As a result, 87,865 gave their informed consent to join our study. Participation rate at health check-up site was about 70%. The participants in the Type 1 survey were more likely to have psychological distress than those in the Type 2 survey, and women were more likely to have psychological distress than men. Additionally, coastal residents were more likely to have higher degrees of psychological distress than inland residents, regardless of sex.Conclusion: This cohort comprised a large sample size and it contains information on the natural disaster, genome information, and metabolome information. This cohort also had several detailed measurements. Using this cohort enabled us to clarify the long-term effect of the disaster and also to establish personalized prevention based on genome, metabolome, and other omics information.

Although ultrasonic diagnostic imaging and fetal heart monitors have undergone great technological improvements, the development and use of fetal electrocardiograms to evaluate fetal arrhythmias and autonomic nervous activity have not been fully established. We verified the clinical significance of the novel signal-averaged vector-projected high amplification ECG (SAVP-ECG) method in fetuses from 48 gravidas at 32-41 weeks of gestation and in 34 neonates. SAVP-ECGs from fetuses and newborns were recorded using a modified XYZ-leads system. Once noise and maternal QRS waves were removed, the P, QRS, and T wave intervals were measured from the signal-averaged fetal ECGs. We also compared fetal and neonatal heart rates (HRs), coefficients of variation of heart rate variability (CV) as a parasympathetic nervous activity, and the ratio of low to high frequency (LF/HF ratio) as a sympathetic nervous activity. The rate of detection of a fetal ECG by SAVP-ECG was 72.9%, and the fetal and neonatal QRS and QTc intervals were not significantly different. The neonatal CVs and LF/HF ratios were significantly increased compared with those in the fetus. In conclusion, we have developed a fetal ECG recording method using the SAVP-ECG system, which we used to evaluate autonomic nervous system development.

Noninvasive risk stratification is important for screening for lethal arrhythmia. We developed a 187-channel signal-averaged vector-projected high-resolution electrocardiograph (187-ch SAVP-ECG) for detecting abnormalities in the spatial location of ventricular high-frequency late potentials (HFLPs) and ventricular repolarization. The subjects consisted of 30 normal controls (CONTROL) and 13 patients with HFLPs (6 with myocardial infarction [MI], 6 with cardiomyopathy, and 1 with Brugada syndrome). The modified X, Y, Z-lead ECG and the synthesized signals from vector-projected 187-channel ECGs were amplified and passed through a digital filter. We calculated the integration of the HFLPs area between QRSend and 30 ms before QRSend. The integrated HFLPs map was superimposed on the corrected recovery time (RTc) and Tpeak-end dispersion maps composed by 187-ch SAVP-ECG. All patients received an examination by 64-channel magnetocardiography (64-ch MCG) on the same day. The spatial distribution of HFLPs by the 187-ch SAVP-ECG map was in agreement with the location of increased RT dispersion in MI. The spatial distribution of HFLPs in DCM demonstrated a wide variety of patterns. Interestingly, the spatial distribution of HFLPs in cases with ARVC was located at around a right ventricular outflow region. The spatial distribution of HFLPs by 187-ch SAVP-ECG was in agreement with those determined by 64-ch MCG. The 187-ch SAVP-ECG might be useful for evaluating the spatial distribution of nonuniform conduction and ventricular repolarization heterogeneity.
