BACKGROUND:
Body mass-independent parameters might be more appropriate for assessing cardiometabolic abnormalities than weight-dependent indices in Asians who have relatively high visceral adiposity but low body fat. Dual-energy X-ray absorptiometry (DXA)-measured trunk-to-peripheral fat ratio is one such body mass-independent index. However, there are no reports on relationships between DXA-measured regional fat ratio and cardiometabolic risk factors targeting elderly Asian men.
METHODS:
We analyzed cross-sectional data of 597 elderly men who participated in the baseline survey of the Fujiwara-kyo Osteoporosis Risk in Men (FORMEN) study, a community-based single-center prospective cohort study conducted in Japan. Whole-body fat and regional fat were measured with a DXA scanner. Trunk-to-appendicular fat ratio (TAR) was calculated as trunk fat divided by appendicular fat (sum of arm and leg fat), and trunk-to-leg fat ratio (TLR) as trunk fat divided by leg fat.
RESULTS:
Both TAR and TLR in the group of men who used ≥ 1 medication for hypertension, dyslipidemia, or diabetes ("user group"; N = 347) were significantly larger than those who did not use such medication ("non-user group"; N = 250) (P < 0.05). After adjusting for potential confounding factors including whole-body fat, both TAR and TLR were significantly associated with low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, fasting serum insulin, and the insulin resistance index in the non-user group and non-overweight men in the non-user group (N = 199).
CONCLUSION
The trunk-to-peripheral fat ratio was associated with cardiometabolic risk factors independently of whole-body fat mass. Parameters of the fat ratio may be useful for assessing cardiometabolic risk factors, particularly in underweight to normal-weight populations.

BACKGROUND:
The Fujiwara-kyo Osteoporosis Risk in Men (FORMEN) study was launched to investigate risk factors for osteoporotic fractures, interactions of osteoporosis with other non-communicable chronic diseases, and effects of fracture on QOL and mortality.
METHODS:
FORMEN baseline study participants (in 2007 and 2008) included 2012 community-dwelling men (aged 65-93 years) in Nara prefecture, Japan. Clinical follow-up surveys were conducted 5 and 10 years after the baseline survey, and 1539 and 906 men completed them, respectively. Supplemental mail, telephone, and visit surveys were conducted with non-participants to obtain outcome information. Survival and fracture outcomes were determined for 2006 men, with 566 deaths identified and 1233 men remaining in the cohort at 10-year follow-up.
COMMENTS
The baseline survey covered a wide range of bone health-related indices including bone mineral density, trabecular microarchitecture assessment, vertebral imaging for detecting vertebral fractures, and biochemical markers of bone turnover, as well as comprehensive geriatric assessment items. Follow-up surveys were conducted to obtain outcomes including osteoporotic fracture, cardiovascular diseases, initiation of long-term care, and mortality.

BACKGROUND:
Limited evidence exists regarding the relationship between central-to-peripheral fat ratio measured by dual-energy X-ray absorptiometry (DXA) and subsequent cardiometabolic risk in both pediatric and adult populations.
METHODS:
The present cohort study investigated the relationship between DXA-measured body fat distribution and cardiometabolic parameters. The source population was 275 4th-6th graders (aged 9.6-12.6 years) in the northeast region of Japan (Shiokawa area in Kitakata). A 3-year follow-up was conducted to obtain complete information from 155 normal-weight children (87 boys and 68 girls). Normal-weight children were identified using sex- and age-specific international cut-offs for body mass index (BMI) based on adult BMI values of 25 kg/m and 18.5 kg/m, respectively. Body fat distribution was assessed using the trunk-to-appendicular fat ratio (TAR) and trunk-to-leg fat ratio (TLR) measured by DXA.
RESULTS:
In boys, systolic blood pressure (SBP) at follow-up showed a significant relationship with TAR at baseline after adjusting for age, height, pubic hair appearance, SBP, and whole body fat at baseline (β = 0.24, P < 0.05), and SBP also showed a significant relationship with TLR after adjusting for confounding factors including whole body fat (β = 0.25, P < 0.05). In girls, there were no significant relationships between blood pressure and TAR/TLR.
CONCLUSION
Body fat distribution in normal-weight boys predicted subsequent blood pressure levels in adolescence. The relationship between fat distribution and blood pressure was independent of fat volume.

This case report describes our first experience performing percutaneous epicardial catheter ablation for Burugada syndrome in our hospital. We describe the good results achieved in this case. The patient was a man in his 30s with no remarkable medical history. However, his family history was notable for the sudden death of his grandfather at age 37 years and his father at age 27 years. While asleep, the patient experienced convulsions and lost consciousness. During emergency transportation, defibrillation was performed 7 times by the ambulance crew. When the patient arrived at our hospital, sinus rhythm was observed on ECG. During resuscitation, Burugada syndrome was diagnosed based on ECG findings. On hospital day 6, an internal cardioverter defibrillator was implanted. After discharge, the defibrillator operated 10 times, so we opted for ablation treatment. Fractionated potential of over 150 ms was confirmed in the right ventricular outflow tract. A low voltage zone of <1 mV could be mapped, and the same site was cauterized a total of 46 times. As a result, ST segment amplitude decreased significantly in lead V1 on ECG. Percutaneous epicardial catheter ablation performed with reference to Nademanee’s report achieved good results in this case of Burugada syndrome.

Abstract
Introduction: Live surgery demonstrations have been widely used in surgical education. However, they cannot be used to demonstrate trauma surgery due to the emergency situation and lack of informed consent. The aim of this study was to conduct a live demonstration of trauma surgery with a porcine model to increase educational opportunities in trauma surgery.
Methods: Live demonstration was conducted at the Center for Development of Advanced Medical Technology (CDAMtec) , Jichi Medical University, Japan. An experienced trauma surgeon instructed three trainees during a live demonstration using pre-planned injuries in a porcine model. A six-point Likert Scale was used on a written survey to determine the value of the program to the viewers. Free-form written comments were also obtained from the participants. Live images of the surgical field were transmitted to a lecture room by a closed wireless LAN with interactive bidirectional audio capability.
Results: Eighty-three participants viewed this live demonstration and completed the questionnaire. Participants were highly satisfied with the live demonstration (mean survey scores: 4.6-5.1/6) , and gave very positive feedback concerning the educational value of this program. Nine free-form comments were submitted, which revealed that the participants felt they could acquire concrete skills for trauma surgery.
Discussion: Live demonstrations for trauma surgery using a porcine model are a feasible and effective educational tool to demonstrate technical procedures and non-technical skills, with possible added advantages regarding the ethical considerations of performing a live surgery demonstration.

[Objective]In recent years, communication skills have been recognized as an essential competence for acupuncturists. This study proposes to develop a scale for measuring the medical communication skills of acupuncturists.
[Materials and Methods]A questionnaire of 20 items was used to measure medical communication skills. These items were adopted from a concept analysis conducted in a previous study.
Cronbach's alpha was used to examine the scale's reliability. The scale's validity was examined by correlation analysis and multiple regression analysis comparisons with normal communication skills subscale scores (ENDCOREs, Encode, Decode, Control, Regulate) and a Japanese version of characteristic trait anxiety scores (STAI, State-Trait Anxiety Inventory).
[Results]Factor analysis, using a principal extraction method and promax rotation, was conducted on responses from 443students and therapists. As a result, the original 20 items were reduced to 16, and the following three factors were extracted:I. Acceptance of patients and self-control;II. Appropriate explanation to patients;and III. Understanding of patient's feelings. These three factors had high degrees of internal consistency (Cronbach's alpha =.872 -.892).
The scores of the three factors correlated significantly with the scores of the six factors of ENDCORE, and with the anxiety scores. Although the results of multiple regression analysis showed that each factor of ENDCORE explained the three factors, the anxiety scores did not influence medical communication skills. The scores for the three factors correlated significantly with self-evaluation scores of medical interview skill. In addition, these three factors were affected by the degree of clinical experience.
[Conclusion]These results suggest that this scale may be a reliable instrument for assessing medical communication skills among Japanese acupuncturists.

BACKGROUND: Repeated application of whole-body periodic acceleration (WBPA) upregulates endothelial nitric oxide synthase and improves brachial artery endothelial function (BAEF) as assessed by measurement of flow-mediated vasodilatation (FMD). However, the acute effect of a single application of WBPA on BAEF has not been fully characterized. In addition, although a novel semi-automatic vessel chasing system (UNEXEF18G) has now been developed in Japan, the direct comparison of UNEXEF18G with a conventional method for FMD measures has not been conducted even if UNEXEF18G has already been utilized in a relatively large scale study. METHODS: We have developed a novel semi-automatic vessel chasing system (UNEXEF18G) that can measure FMD on-line, identify time to peak vasodilatation (TPV), and determine the area under the vasodilatation curve (AUC). Thus, 45 min of WBPA was applied in 20 healthy volunteers (age, 34 +/- 13 years), and BAEF was measured by UNEXEF18G before and after WBPA. Also, UNEXEF18G measured FMD was compared with those of a conventional FMD measurement method at rest in order to validate a novel UNEXEF18G measured FMD. RESULTS: Single WBPA resulted in a significant increase in FMD (from 6.4 +/- 3.4 to 10.7 +/- 4.3%, p < 0.01), a significant decrease in TPV and a significant increase in AUC. In the validation study for UNEXEF18G, Bland and Altman analysis showed that UNEXEF18G measured FMD was almost identical to those of the conventional method at rest. CONCLUSION: These data suggest the usefulness of a new UNEXEF18G and that single application of WBPA results in acute improvement in BAEF in humans.

Objective: To investigate quantitatively the risk factors of hyperkalaemia or increased blood potassium associated with ACE-inhibitor therapy
Design: Nested case-control study
Methods: We used the antihypertensive drug database(72,379 subjects)developed by the RAD-AR Council, Japan and the Institute of Statistical Mathematics based on the post-marketing surveillance(PMS) data of pharmaceutical companies. Of 37,372 subjects taking ACE-inhibitors, the case group was composed of 64 patients who experienced hyperkalaemia or blood potassium increase while taking ACE-inhibitors, and the control group was composed of 1,280 patients(20 patients per case)randomly selected from patients who did not experience hyperkalaemia or blood potassium increase while taking ACE-inhibitors. The relevant factors that can be extracted from the database were the followings: age, WHO classification of hypertension, complications, antihypertensive drugs used before the PMS survey, and concomitant drugs.
Results: Among the subjects taking antihypertensive agents, 65 patients experienced hyperkalaemia orincreased blood potassium, 64(98.5%)of whom were taking ACE-inhibitors. The factors that were significantly different between two groups(p<0.05)by univariate analysis were WHO classification of hypertension(p=0.005), complications of nephritis/nephrosis(p<0.001), other disorder of urinary system(p<0.001), unclear symptom or diagnosis(p=0.005), taking diuretics as antihypertensive drugs before study(p=0.032), and concomitant treatment with diuretics(p=0.004), vasodilators(p<0.001), and antigout agents(p=0.001). Conditional multivariate logistic analysis of these factors yielded adjusted odds ratio of 21.31 for complications of nephritis/nephrosis(p<0.001), 6.83 for other disorder of urinary system(p<0.001), and 2.30 for concomitant therapy with diuretics(p=0.049).
Conclusion: The risk factors of hyperkalaemia or blood potassium increase associated with taking ACE-inhibitors were nephritis/nephrosis, other disorder of urinary system and concomitant therapy with diuretics.

Apical ballooning cardiomyopathy (Takotsubo or ampulla cardiomyopathy) is a well-known transient and localized left ventricular (LV) dysfunction characterized by apical severe hypokinesis, typical electrocardiogram (ECG) changes of negative T, and a lack of organic lesions of the coronary arteries which could cause myocardial ischemia leading to segmental asynergy. Here we report on two cases of transient cardiomyopathy showing atypically localized asynergy, which is different from Takotsubo cardiomyopathy. Case 1 was diagnosed as atypical Takotsubo cardiomyopathy, and the current findings suggest case 2 was viral myocarditis. These cases suggest that there exist variant patterns of transient cardiomyopathy, and non-invasive and serial clinical evaluations are important for differential diagnosis in acute and atypical cardiomyopathy.
