Background Normal values for echocardiographic measurements and the relationship between these parameters and age in a large Japanese population are still unknown. Methods and Results A total of 700 healthy Japanese aged 20-79 years underwent 2-dimensional and Doppler echocardiography at collaborating institutions. The respective mean values obtained in men and women were as follows: septal wall thickness, 0.9±0.1 and 0.8±0.1 cm; posterior wall thickness, 0.9±0.1 and 0.8±0.1 cm; left ventricular (LV) diastolic diameter, 4.8±0.4 and 4.4±0.3 cm; LV systolic diameter, 3.0±0.4 and 2.8±0.3 cm; LV diastolic volume, 93±20 and 74±17 ml; LV systolic volume, 33±20 and 25±7 ml; LV ejection fraction, 64±5 and 66±5%; maximum left atrial (LA) volume, 42±14 and 38±12 ml. Aortic root diameter, LV wall thickness, and LV mass slightly increased with age, whereas indexed LA volume did not vary with age. Diastolic parameters assessed by mitral inflow and mitral annular velocities declined with age, as previously reported. Conclusions Normal values of echocardiographic measurements in a large Japanese population are reported for the first time; several systolic and diastolic parameters varied with age. These results provide important reference values that should be useful in routine clinical practice as well as in clinical trials. (Circ J 2008; 72: 1859 - 1866)

Background:Waon therapy improves heart failure (HF) symptoms, but further evidence in patients with advanced HF remains uncertain.Methods and Results:In 19 institutes, we prospectively enrolled hospitalized patients with advanced HF, who had plasma levels of B-type natriuretic peptide (BNP) >500 pg/ml on admission and BNP >300 pg/ml regardless of more than 1 week of medical therapy. Enrolled patients were randomized into Waon therapy or control groups. Waon therapy was performed once daily for 10 days with a far infrared-ray dry sauna maintained at 60℃ for 15 min, followed by bed rest for 30 min covered with a blanket. The primary endpoint was the ratio of BNP before and after treatment. In total, 76 Waon therapy and 73 control patients (mean age 66 years, men 61%, mean plasma BNP 777 pg/ml) were studied. The groups differed only in body mass index and the frequency of diabetes. The plasma BNP, NYHA classification, 6-min walk distance (6MWD), and cardiothoracic ratio significantly improved only in the Waon therapy group. Improvements in NYHA classification, 6MWD, and cardiothoracic ratio were significant in the Waon therapy group, although the change in plasma BNP did not reach statistical significance. No serious adverse events were observed in either group.Conclusions:Waon therapy, a holistic soothing warmth therapy, showed clinical advantages in safety and efficacy among patients with advanced HF.

In patients with acute myocardial infarction (MI), coronary microvasculatures are often damaged irreversibly due to myocardial ischemia and reperfusion, and flow to the previously ischemic myocardium is markedly reduced, a phenomenon known as the “no-reflow phenomenon”. Percutaneous coronary intervention (PCI) may accelerate embolization of plaque gruels and microthrombi to the microvessels, which further reduces tissue perfusion. The extent of the no-refl ow zone correlates with infarct size, and it has additional prognostic information. Recent advances in imaging modalities have enabled us to diagnose the no-reflow phenomenon and to assess the mechanisms of the no-refl ow phenomenon. Pharmacological interventions and catheter-based devices to retrieve embolic materials have been proposed, and some of them are associated with improvement in clinical outcomes. Thus, we should keep in mind that only the achievement of complete microvascular perfusion is associated with better functional and clinical outcomes in patients with acute MI.

Relatively little is known about the distribution of avian paramyxoviruses (APMVs) among wild birds in Japan. Surveillance of APMV in migratory waterfowl was conducted in the San-in region of western Japan during winters of 2006 to 2012. A total of 16 avian paramyxoviruses consisting of 3 lentogenic Newcastle disease viruses (NDVs), 12 APMV-4 and 1 APMV-8 were isolated from 1,967 wild-bird fecal samples. The results show that NDV and APMV-4 are relatively widely distributed among wild waterfowl that migrate to Japan from northern regions. Phylogenetic analysis revealed that there was no genetic relationship between the isolates from wild birds and domestic poultry in Japan. However, surveillance of APMVs in wild waterfowl needs to be conducted due to the pathogenic potential of these isolates in domestic poultry.

Urinary citrate output was studied in 5 cases of primary aldosteronism, in 3 of Addison's disease and in 8 of normal subjects. The urinary citrate output was decreased in 4 of 5 cases of primary aldosteronism, and the citrate output could not be normalized by removal of adrenocortical adenoma. In patients with primary aldosteronism citrate excretion was somewhat increased by admini-stration of potassium chloride, but rather decreased by spironolactone. In these patients urinary citrate output could not be correlated with either plasma CO2 content or plasma potassium concentration. The low urinary citrate excretion in primary aldosteronism may not be satisfactorily explained either by direct action of aldosterone on the kidney or by intracellular acidosis.

Aims: MND-2119 is a novel once-daily dose self-emulsifying formulation of highly purified eicosapentaenoic acid ethyl ester (EPA-E) and is approved as an antihyperlipidemia agent in Japan. It has improved absorption and achieves higher plasma EPA concentrations at Cmax than conventional EPA-E. In the JELIS trial, concomitant use of EPA-E with statin therapy significantly reduced atherosclerotic cardiovascular disease (ASCVD) risks. As a potential mechanism of action of EPA, endogenous formation of EPA-derived anti-inflammatory metabolites is receiving greater attention. This study aims to investigate the endogenous formation of EPA-derived anti-inflammatory metabolites following single and multiple administrations of MND-2119. Methods: Healthy adult male subjects were randomly assigned to a nonintervention (control) group, MND-2119 2-g/day group, MND-2119 4-g/day group, or EPA-E 1.8-g/day group for 7 days (N=8 per group). Plasma fatty acids and EPA-derived metabolites were evaluated. Peripheral blood neutrophils were isolated, and the production of EPA-derived metabolites from in vitro stimulated neutrophils was evaluated. Results: After single and multiple administrations of MND-2119 2 g/day, there were significant increases in plasma EPA concentration, 18-hydroxyeicosapentaenoic acid (18-HEPE), and 17,18-epoxyeicosatetraenoic acid compared with those of EPA-E 1.8 g/day. They were further increased with MND-2119 4 g/day administration. In neutrophils, the EPA concentration in the MND-2119 2-g/day group was significantly higher compared with that in the EPA-E 1.8-g/day group after multiple administration, and 18-HEPE production was positively correlated with EPA concentration. No safety issues were noted. Conclusions: These results demonstrate that MND-2119 increases the plasma and cellular concentrations of EPA and EPA-derived metabolites to a greater extent than conventional EPA-E formulations.

The goal of this study is to perform correlation analysis of Computed tomography (CT) and magnetic resonance imaging (MRI) results in posterior ligament complex (PLC) injury and define the morphological traits of thoracolumbar (TL) burst fractures connected to PLC injury. Forty patients with surgically repaired TL burst fractures between January 2013 and December 2020 were retrospectively analyzed. The patients were split into two groups for comparison based on MRI (Group P: patients with a confirmed or suspected PLC injury; Group N: patients with PLC injury denied). The radiographic morphological examination based on CT scans and clinical evaluation was performed and compared between two groups. The thoracolumbar injury classification and severity score (TLICS), the load sharing classification (LSC) scores, and the number of patients with neurological impairments were considerably greater in Group P. Loss of height of the fracture (loss height), local kyphosis of the fracture (local kyphosis), and supraspinous distance were significantly higher in Group P and significantly associated with PLC injuries indicating severe vertebral body destruction and traumatic kyphosis in multivariate logistic analysis [odds ratio: 1.90, 1.06, and 1.13, respectively]. Cutoff value for local kyphosis obtained from the receiver operating characteristic curve was 18.8. If local kyphosis is greater than 18.8 degrees on CT scans, we should take into account the probability of the highly damaged burst fracture associated with PLC injury. In this situation, we should carefully assess MRI to identify the spinal cord injury or spinal cord compression in addition to PLC injury because these instances likely present with neurological abnormalities.

Background: Transcatheter mitral valve repair with the MitraClip system has been established in selected high-risk patients. The MitraClip procedure results in a relatively large iatrogenic atrial septal defect (iASD). This study aimed to investigate the prevalence and clinical course of iASD requiring transcatheter closure following the MitraClip procedure.Methods and Results: This study was conducted at all 59 institutions that perform transcatheter mitral valve repair with the MitraClip system in Japan. The data of patients on whom transcatheter iASD closure was performed were collected. Of the 2,722 patients who underwent the MitraClip procedure, 30 (1%) required transcatheter iASD closure. The maximum iASD size was 9±4 mm (range, 3–18 mm). The common clinical course of transcatheter iASD closure was hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt. Of the 30 patients, 22 (73%) required transcatheter closure within 24 h following the MitraClip procedure, including 12 with hypoxemia and 5 with right-sided heart failure complicated with cardiogenic shock. Of the 5 patients, 2 required mechanical circulatory support devices. Twenty-one patients immediately underwent transcatheter iASD closure, and hemodynamic deteriorations were resolved; however, 1 patient died without having undergone transcatheter closure.Conclusions: Transcatheter iASD closure was required in 1% of patients who underwent the MitraClip procedure. Many of these patients immediately underwent transcatheter iASD closure because of hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt.

明治維新前後において、福沢諭吉ら洋学者達が近代科学を子どもにまで広めようとした。なかでも江戸末期の1868年(明治元年)に福沢諭吉が発行した『訓蒙窮理圖解 初編 上(中・下)』(上巻は表裏表紙含め全52葉)は、すべての漢字にルビを付し、所々にその頁の内容に沿った図などを挿入するなどはじめて子どもを対象とした科学読み物であったと考えられる。その後、この書物に触発されて明治五年から明治七年にかけて「窮理熱」と呼ばれる科学読み物がさかんに出版されるようになり、科学入門書の一大ブームが起きた。これは科学入門書が一般庶民の読み物として広がりつつあった事を裏付けるものである。こういった科学書が一般庶民の読み物として成立するためには、読者層において高いレベルの識字率が必要とされるのが前提である。さらに、各種の研究から明治維新前後の一般庶民の識字率は相当に高かったことが知られている。そこで本稿では、一般庶民にまで教育が施されるのはいつのことからであり、その教授法はどのようなものであったのかについて明治維新前後の当時の資料をもとにして考察していきたい。

Background:Coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFRCT) is an established tool for identifying lesion-specific ischemia that is now approved for use by the Japanese insurance system. However, current clinical reimbursement is strictly limited to institutions with designated appropriate use criteria (AUC). This study assessed differences in physicians’ behavior (e.g., use and interpretation of FFRCT, final management) according to Japanese AUC and non-AUC site designation.Methods and Results:Of 5,083 patients in the ADVANCE Registry, 1,829 from Japan were enrolled in this study. Physicians’ behavior after interrogating CCTA and FFRCTwas analyzed separately according to AUC and non-AUC site designation. Compared with AUC sites, patients referred for FFRCTfrom non-AUC sites had a higher rate of negative FFRCT, less severe anatomic stenosis, and a slightly lower rate of management plan reclassification (51.2% vs. 61.3%), with near-identical utility in both groups. Actual care corresponded equally well to post-FFRCTplans in both groups. The likelihood of revascularization for positive or negative FFRCTwas similar between the 2 groups. Importantly, AUC and non-AUC sites were equally unlikely to revascularize patients with negative FFRCTand stenosis >50% or patients with positive FFRCTand stenosis <50%.Conclusions:Compared with AUC sites, non-AUC sites had lower disease burden and reclassification of management plans, but nearly identical clinical integration. Actual care corresponded equally well to post-FFRCTrecommendations at both sites.

Background:A therapeutic strategy in patients with atrial septal defect (ASD) and significant pulmonary arterial hypertension (PAH) remains controversial. This study aimed to assess the effect of PAH-specific medications and subsequent transcatheter shunt closure (ie, a treat and repair strategy) in these patients.Methods and Results:Among 646 patients with ASD, 22 patients (mean age of 56±20 years) who had PAH [mean pulmonary artery pressure ≥25 mmHg and pulmonary vascular resistance (PVR) ≥3 Wood units] underwent successful transcatheter ASD closure. Prior to the procedure, 8 patients received PAH-specific medications (PHM group) and 14 patients did not (non-PHM group). Initially, the PHM group had higher PVR compared with non-PHM group (9.6±3.8 vs. 4.2±1.0 Wood units, P<0.01). After treatment with PAH-specific medications, PVR in this group decreased to 4.0±0.8 Wood units (P<0.01). No adverse events were observed in either the PHM or non-PHM group during or after the transcatheter procedure. In the PHM group, during a treatment period of 52±48 months, the World Health Organization Functional Classification significantly improved (3.0±0.5 to 2.0±0.0, P<0.01), as well as in the non-PHM group (2.1±0.6 to 1.5±0.5, P<0.01).Conclusions:Treat and repair strategy provided substantial improvement and no worsening of the WHO-FC, even in patients with ASD and significant PAH. Long-term hemodynamic follow-up is mandatory to evaluate the ultimate efficacy and safety of this new strategy. (Circ J 2016; 80: 227–234)

Background: The objective of the present analyses was to describe the baseline characteristics and treatment of the Japanese patients with HFrEF in THE PARALLEL-HF study. Methods and Results: Key demographic, clinical and laboratory findings, along with treatment, were reported and compared with patients enrolled in the PARADIGM-HF trial and other contemporary randomized clinical trials and registries of Japanese patients with HFrEF. In addition, the MAGGIC and EMPHASIS-HF risk scores were calculated. A total of 225 Japanese patients were randomized in PARALLEL-HF with a mean age of 67.9 years and the majority of the patients being male (85.8%) and in NYHA Class II (93.8%). Key baseline characteristics in PARALLEL-HF were generally comparable with PARADIGM-HF, and other contemporary clinical trials and registries of Japanese HFrEF patients. Patients enrolled in PARALLEL-HF were well treated with conventional evidence-based therapy at baseline (angiotensin-converting enzyme inhibitor inhibitor/angiotensin receptor blocker, 62.7%/37.3%; β-blockers, 94.7%; mineralocorticoid receptor antagonist, 59.1%). Despite the evidence-based treatment and most patients being in NYHA Class II, these patients had a low LVEF (mean 28.1%) and were at high risk of cardiovascular mortality and morbidity as assessed by the MAGGIC and EMPHASIS-HF risk scores. Conclusions: Overall, the patients in PARALLEL-HF were largely representative of contemporary ambulatory patients with HFrEF who are well treated with evidence-based therapies. PARALLEL-HF will determine whether sacubitril/valsartan provides similar improvements in clinical outcomes in Japanese HFrEF patients as observed in the PARADIGM-HF study.

本稿は、法的親子関係の成否をめぐって社会的に注目された裁判事例を素材に、そこでの議論の多くが血縁関係の存否という事実に目を奪われ、法的親子関係の本質を見落としているとの視点から、改めて法的親子関係の市民社会法における本来的意義、機能を確認しておこうとするものである。市民社会法の論理からは、法的親子関係に血縁を無媒介に反映させることは許されず、保護義務の強制を根拠づける契機は自由な意思にこそ求められるべきであることを論じる。

Background: Many studies have focused on disease causality, but few of them deal with health-promoting factors. Thus, we examined the effect of having a sense of purpose in life (ikigai) on mortality from cardiovascular disease (CVD). Methods: In 1988, we conducted a prospective cohort study of 2,959 Japanese subjects, ranging in age from 40 to 74 years, and followed them till the end of 2003. The level of their sense of purpose in life was evaluated by a self-administered questionnaire. After excluding those with a history of heart disease, stroke, or malignant tumor, 1,618 subjects (832 men and 786 women) who had completed the questionnaire were used in the analyses with Cox's proportional hazards model. Results: During the average 13.3 years of follow up, 249 deaths (172 men and 77 women) occurred as a result of all causes: 32 from heart disease, 31 from stroke, 63 from CVD, and 104 from malignant tumors. The adjusted hazard ratios for death in men with a strong sense of purpose in life, as compared with those with a low sense of purpose, were 0.28 (95% confidence interval: 0.10-0.84) for stroke, 0.56 (0.28-1.10) for CVD, and 0.62 (0.45-0.86) as a result of all causes. In women, no significant relationship was found between having a sense of purpose in life and mortality; this was possibly because the smaller number of deaths reduced the statistical significance. Conclusion: We found that in men, having a sense of purpose in life affected the risk of death as a result of all causes, stroke, and CVD.

Background: The purpose of the present study was to investigate gender differences in age-related changes of left ventricular (LV) and right ventricular (RV) geometries and functions throughout the entire adult age range using the Japanese Normal Values for Echocardiographic Measurements Project (JAMP) study database. Methods and Results: Seven hundred healthy volunteers (aged 20-79 years) underwent 2-dimensional and Doppler echocardiography. The subjects were stratified into 6 different age groups and then stratified by gender in each age group. LV diastolic function was assessed from pulsed wave Doppler measurements of mitral early (E) and late (A) inflow velocities and tissue Doppler measurements of mitral early (e') and late (a') annular velocities. LV volume decreased and LV mass increased with age to a similar extent in both men and women. Furthermore, for subjects <50 years, women had significantly greater E, E/A ratio and e' than men, but these parameters were similar between genders in subjects >50 years. In addition, there was a significant interaction between age and gender that affected the differences in E, e' and E/e' among the groups (P<0.03, P<0.01, and P<0.03, respectively; ANOVA). There were no gender differences in age-related changes in RV parameters. Conclusions: Gender differences were found in age-related changes in LV diastolic function in a healthy population. Gender differences should be considered for optimal diagnosis and management of cardiovascular disease. (Circ J 2011; 75: 2840-2846)

Background: The recently developed real-time 3-dimensional echocardiography (RT3DE) is a promising imaging method to quantify cardiac chamber volumes and their functions in clinical practice. However, normal reference values of RT3DE parameters have not been fully investigated in a large, healthy Japanese population. Methods and Results: This study consisted of 410 healthy subjects aged from 20 to 69 years who had a RT3DE at one of the 23 collaborating institutions. All subjects had no history of cardiac disease and no risk factors. The mean values in men and women were as follows: 50±12ml/m2 and 46±9ml/m2 for left ventricular (LV) end-diastolic volume index, 19±5ml/m2 and 17±4ml/m2 for end-systolic volume index, 61±4% and 63±4% for ejection fraction, 64±12g/m2 and 56±11g/m2 for mass index, 23±6ml/m2 and 24±6ml/m2 for left atrial (LA) maximum volume index, 10±3ml/m2 and 10±3ml/m2 for minimum volume index, and 58±6% and 58±6% for percent volume change. LV sizes decreased with age, whereas LV mass index did not change. LA sizes slightly increased with age. Conclusions: This multicenter investigation determined normal reference values for LV and LA sizes, and their functional parameters on RT3DE in a large, healthy Japanese population. The results of the present study support the use of RT3DE for the diagnosis and management of cardiovascular disease. (Circ J 2012; 76: 1177-1181)
