Background: No consensus exists regarding which anthropometric measurements are related to bone mineral density (BMD), and this relationship may vary according to sex and age. A large Japanese cohort was analyzed to provide an understanding of the relationship between BMD and anthropometry while adjusting for known confounding factors. Methods: Our cohort included 10,827 participants who underwent multiple medical checkups including distal forearm BMD scans. Participants were stratified into four groups according to age (≥50 years or <50 years) and sex. The BMD values were adjusted for confounding factors, after which single and partial correlation analyses were performed. The prevalence of osteopenia was plotted for each weight index (weight or body mass index [BMI]) class. Results: Cross-sectional studies revealed that weight was more favorably correlated than BMI in the older group (R=0.278 and 0.212 in men and R=0.304 and 0.220 in women, respectively), whereas weight and BMI were weakly correlated in the younger age groups. The prevalence of osteopenia exhibited a negative linear relationship with weight among older women ≥50 years of age, and an accelerated increase was observed with decreasing weight in older men weighing <50 kg and younger women weighing <60 kg. When weight was replaced with BMI, the prevalence was low in most subgroups classified by weight. Conclusions Weight, rather than BMI, was the most important indicator of osteopenia but it might not be predictive of future bone loss.

Purpose: Quantitative elastography methods, such as ultrasound two-dimensional shear-wave elastography (2D-SWE) and magnetic resonance elastography (MRE), are used to diagnose liver fibrosis. The present study compared liver stiffness determined by 2D-SWE and MRE within individuals and analyzed the degree of agreement between the two techniques. Methods: In total, 888 patients who underwent 2D-SWE and MRE were analyzed. Bland-Altman analysis was performed after both types of measurements were log-transformed to a normal distribution and converted to a common set of units using linear regression analysis for differing scales. The expected limit of agreement (LoA) was defined as the square root of the sum of the squares of 2D-SWE and MRE precision. The percentage difference was expressed as (2D-SWEMRE)/ mean of the two methods×100. Results: A Bland-Altman plot showed that the bias and upper and lower LoAs (ULoA and LLoA) were 0.0002 (95% confidence interval [CI], -0.0057 to 0.0061), 0.1747 (95% CI, 0.1646 to 0.1847), and -0.1743 (95% CI, -0.1843 to -0.1642), respectively. In terms of percentage difference, the mean, ULoA, and LLoA were -0.5944%, 19.8950%, and -21.0838%, respectively. The calculated expected LoA was 17.1178% (95% CI, 16.6353% to 17.6002%), and 789 of 888 patients (88.9%) had a percentage difference within the expected LoA. The intraclass correlation coefficient of the two methods indicated an almost perfect correlation (0.8231; 95% CI, 0.8006 to 0.8432; P<0.001). Conclusion Bland-Altman analysis demonstrated that 2D-SWE and MRE were interchangeable within a clinically acceptable range.

The Medical Safety Committee has conducted various activities for patient safety in Japanese traditional Kampo medicines. In this study, we conducted a questionnaire survey to promote the prevention of medical accidents and their recurrence. We received responses from 15 of 19 facilities specializing in Kampo medicine and collected a total of 247 incident and accident cases in the field of Kampo medicine. Cases of side effects included interstitial pneumonia caused by Kampo prescriptions containing Scutellariae Radix, aconite poisoning, and licorice-induced pseudoaldosteronism. Furthermore, we also collected decoction-specific cases, which are unique to facilities specializing in Kampo medicine, for the first time. From the results, we included the following seven points for risk management in the field of Kampo medicine : 1) insufficient recognition to the side effects of Kampo medicines, 2) misunderstanding of the dosages of Kampo products, 3) errors due to similarities in Kampo formulas and crude drug names, 4) preconception of frequently used Kampo prescriptions, 5) contamination in the decoctions, 6) errors related to crude drug items and their dosages that are frequently added or subtracted, 7) errors in hospital wards.

The Medical Safety Committee analyzed the case reports of minor incidents from the pharmacies last time as part of an activity to promote patient safety in Japanese traditional Kampo medicine. This time, we analyzed the case reports of medical accidents and minor incidents from the medical institutions. We extracted 626 reports related to Kampo products from the public database, which the Japan Council for Quality Health Care has established based on the collected information related to the medical accidents and minor incidents. The medical accident information includes case reports related to drug-induced liver injury. The minor incident reports include prescribing error due to misinterpretation related to the quantity of one sachet of Kampo extract product, dispensing error due to similarity of product appearance, number or name, and administration error due to judging the medicine only by Kanji characters or product company names without checking the Kampo formula name. Additionally, the minor incidents were often discovered by people belonging to different professions or patients themselves. In order to promote patient safety, knowledge about these incidents should be shared among the people involved in the same or different professions.

We conducted a questionnaire survey on shift and on-call system targeting under-forty cardiovascular surgeons and obtained responses from 35 surgeons. We report the questionnaire results.

The Japan society of oriental medicine created a committee of medical safety in 2017. The first activity was to summarize the representative side effects of Kampo medicine and to enlighten members of our society about them. In this report, we documented the knowledge to keep in mind at present on pseudoaldosteronism, drug-induced liver injury, and drug-induced lung injury. Since these three major side effects may cause clinically severe conditions, it is very important to detect them early and take appropriate measures. Therefore, proper examinations at the right time are necessary while taking Kampo medicine.

Background/Aims: While Helicobacter pylori (HP)-negative gastric cancer is frequently reported, little is known about the predictors for detecting HP-negative early gastric cancer (EGC). We aimed to evaluate the predictors for the detection of HP-negative EGC. Methods: We retrospectively reviewed 13,477 consecutive asymptomatic cases where upper endoscopy was performed by nine physicians from April 2017 to March 2019 and analyzed the detection rate of high-risk lesions (HRLs), including EGC, tubular adenoma, and lymphoma, according to the status of HP infection. The observation time was corrected for multiple regression analyses. Results: For all physicians, the average observation time for screening HP-eradicated and -naïve patients was shorter than that for screening HP-positive patients (p<0.05). Multiple regression analyses revealed that the observation time in the three groups was an independent predictor for detecting HRLs in HP-eradicated patients (p=0.03106, 0.01263, and 0.02485, respectively), while experience of endoscopy was an independent predictor for detecting HRLs in HP-naïve patients (p=0.02638). Conclusions While observation time during screening endoscopy was a quality indicator for detecting HRLs in HP-eradicated patients, experience of endoscopy was a quality indicator for detecting HRLs in HP-naïve patients.

OBJECTIVES: Sarcopenia, decreased muscle volume and muscle weakness in the elderly is a serious risk of various adverse outcomes. Current diagnostic procedure for sarcopenia includes gait speed, grip strength, and percentage of skeletal muscle volume. However, lower leg muscle strength decreases much faster than grasp power, and we have evaluated the usefulness of its measurement using a recently developed instrument (Locomoscan). METHODS: Forty-three institutionalized elderly subjects were evaluated for their anthropometrical parameters, body composition, grasp and lower leg muscle strength, and gait speed. They were categorized into 2 groups; gait speed equal to or higher than 0.8 m/s and that below 0.8 m/s. RESULTS: Leg muscle strength per body weight was significantly greater in those with their gait speed equal to or higher than 0.8 m/s, whereas there was no significant difference in other parameters. Receiver operator characteristics analysis has shown that leg muscle alone significantly predicted the greater gait speed. CONCLUSIONS: Lower leg muscle strength can be useful for predicting gait speed.

　　Our ward encounters many cases (approximately 80 every year) requiring end-of-life care. The experiences of nurses, as well as of patients’ families and friends, vary widely and nurses appear to be anxious about providing mortuary care, known as Angel care. There is no standardized manual, and therefore medical care professionals need to optimize good Angel care practices in order to alleviate nurses’ anxiety around the issue. We administered a questionnaire regarding the situation of Angel care to 208 ward nurses in our hospital and extracted difficulties in providing Angel care reported by the 173 respondents. Less than 5% of nurses, regardless of length of nursing experience, experienced no anxiety. Nurses found it difficult to conduct basic technical procedures: 51.7% had difficulties in closing the deceased patient’s mouth and 40.2% had difficulties judging whether the results of mortuary makeup resemble antemortem appearance. Ninety-five percent of nurses wished to study Angel care in the future should learning materials be available. In conclusion, more than half of nurses were anxious about providing Angel care regardless of length of their nursing experience and number of cases handled. Nurses are greatly interested in Angel care and wish to learn more if learning materials are made available.
