The seating location in the classroom is thought to have a close relationship to the aca demic performance of each student. However, as teachers taking part in higher educa tion, we know that "common sense" must give way to many exceptional cases. To verify the truth of this widely held belief, we recorded the students' seating locations at a den tal hygiene college for many years, and correlated this information with their academic performance. As the rooms in which they were taught were identical, and the seating ar rangements were consistent throughout the years, it allowed us to analyze the data in a single environment. Many studies have reported that although students with poor grades sit in "low interaction" seats, students with good grades do not select "high interaction"seats, but rather prefer to occupy "moderate interaction" seats. Average or middle stu dents tended to have no favored location. We were not able to correlate each student's academic performance with her preferred seating location, especially in the case of high performing students. However, the pre ferred seating location for students with poor grades tended to follow commonly ac cepted norms which have been described in many reports. Our findings suggest that stu dents who are at risk of failing could be determined by where they sit in the classroom. This helps to identify the potentially unsuccessful candidates, and permits remedial ac tion at an early stage. (J Osaka Dent Univ 2017; 51: 151-156)

Atrial fibrillation (AF) is the most common cardiac rhythm disorder and a major risk factor for stroke. For more than 60 years, warfarin has been the only approved anticoagulant for prevention of stroke in patients with AF. Although highly effective, it has many limitations that make its use difficult. Therefore, several novel anticoagulants are under development to overcome the limitations of warfarin, and some of these have entered phase III clinical trials. Dabigatran is an oral, reversible direct thrombin inhibitor approved in Europe and in several other countries for the prevention of venous thromboembolism after elective knee and hip replacement surgery. It has also been approved in the United States and Japan for the prevention of stroke and systemic embolism in patients with nonvalvular AF. In this review, the mechanism of action and pharmacological properties of new anticoagulants are described in detail, and the correct use of dabigatran in clinical practice is discussed.

Background:Because the influence of digitalis use on the death of patients with non-valvular atrial fibrillation (NVAF) remains controversial, a subanalysis of the J-RHYTHM Registry was performed.Methods and Results:A consecutive series of outpatients with AF from 158 institutions was enrolled and followed for 2 years or until the occurrence of an event. Among 7,406 patients with NVAF, 7,018 (age, 69.7±10.0 years; men, 71.1%) with information on antiarrhythmic drug and digitalis use at baseline were divided into 2 groups based on digitalis use. The influence of digitalis on death was investigated using a propensity score-matching model. In 802 patients treated with digitalis, all-cause death was significantly higher than in 6,216 patients with no digitalis use during the 2-year follow-up period (4.4% vs. 2.4%, unadjusted P<0.001). Digitalis use was significantly associated with all-cause death in the crude model (hazard ratio [HR] 1.85, 95% confidence interval [CI] 1.28–2.68, P=0.001). However, after propensity score-matching, the association was not significant (HR 1.31, 95% CI 0.70–2.46, P=0.405). Older age, male sex, heart failure, coronary artery disease, and lower body mass index were significantly associated with all-cause death in NVAF patients treated with digitalis.Conclusions:Digitalis use was not independently associated with all-cause death, and several clinical confounding factors might contribute to increased mortality in NVAF patients treated with digitalis.

Background:It is disputed whether the risk of cardiogenic embolism varies with type of atrial fibrillation (AF). Although several studies have found that the risk of cardiogenic embolism was similar among paroxysmal and persistent/permanent AF, a few studies have found that patients with paroxysmal AF had a lower rate of stroke and systemic embolism than those with persistent/permanent AF. In the present study, post-hoc analysis of the J-RHYTHM Registry was done to compare the risk of thromboembolic events among 3 types of non-valvular AF (NVAF).Methods and Results:A total of 7,406 NVAF patients were followed up prospectively for 2 years. At baseline, warfarin was used for 78.6%, 90.0%, and 91.8% of patients with paroxysmal, persistent, and permanent AF, respectively. There were 126 thromboembolic events during the follow-up period. The crude event rate was 2-fold higher among the patients with permanent NVAF (2.29%) than among those with paroxysmal (1.16%) or persistent (1.20%) NVAF (P=0.001). After adjusting for warfarin use and CHA2DS2-VASc score components, however, the hazard ratio for thromboembolism did not differ between paroxysmal (reference) and permanent NVAF (1.007; 95% confidence interval: 0.955–1.061).Conclusions:The crude rate of thromboembolic events was higher in permanent NVAF than in paroxysmal NVAF, but after adjusting for warfarin use and CHA2DS2-VASc score components, paroxysmal and permanent NVAF patients had similar risk of thromboembolism.

Background: This sub-analysis of the ANAFIE Registry, a prospective, observational study of >30,000 Japanese non-valvular atrial fibrillation (NVAF) patients aged ≥75 years, assessed the prevalence of direct oral anticoagulant (DOAC) under-dose prevalence, identified the factors of under-dose prescriptions, and examined the relationship between DOAC dose and clinical outcomes.Methods and Results: Patients, divided into 5 groups by DOAC dose (standard, over-, reduced, under-, and off-label), were analyzed for background factors, cumulative incidences, and clinical outcome risk. Endpoints were stroke/systemic embolic events (SEE), major bleeding, and all-cause death during the 2-year follow-up. Of 18,497 patients taking DOACs, 20.7%, 3.8%, 51.6%, 19.6%, and 4.3%, were prescribed standard, over-, reduced, under-, and off-label doses. Factors associated with under-dose use were female sex, age ≥85 years, reduced creatinine clearance, history of major bleeding, polypharmacy, antiplatelet agents, heart failure, dementia, and no history of catheter ablation or cerebrovascular disease. After confounder adjustment, under-dose vs. standard dose was not associated with the incidence of stroke/SEE or major bleeding but was associated with a higher mortality rate. Patients receiving an off-label dose showed similar tendencies to those receiving an under-dose; that is, they showed the highest mortality rates for stroke/SEE, major bleeding, and all-cause death.Conclusions: Inappropriate low DOAC doses (under- or off-label dose) were not associated with stroke/SEE or major bleeding but were associated with all-cause death.

Aim: Epicardial adipose tissue (EAT) is a pathogenic fat depot that may be associated with coronary atherosclerosis and cardiovascular events. Because eicosapentaenoic acid (EPA) has been reported to exert cardiovascular protective effects, we aimed to assess the effects of EPA on the volume of visceral adipose tissue, including EAT and abdominal visceral adipose tissue (AVAT), using multislice computed tomography (CT). Methods: In 30 patients with coronary artery diseases (9 women; mean age, 67.2±5.4 years), EAT and AVAT volumes were compared between the control group (n=15, conventional therapy) and the EPA group (n=15, conventional therapy plus purified EPA 1800 mg/day) during a six-month period. EAT was defined as any pixel that had CT attenuation of -150 to -30 Hounsfield units (HU) within the pericardial sac. Results: After the six-month follow-up, the serum EPA level increased from 59.9±18.8 to 177.2± 3.3 μg/mL in the EPA group (p<0.01), but no increase was noted in the control group. Similarly, the EPA/arachidonic acid (AA) ratio increased from 0.39±0.12 to 1.22±0.28 in the EPA group (p<0.01), with no significant increase in the control group. The AVAT and EAT volumes decreased in the EPA group but were unchanged in the control group (AVAT, −11.6±17.0 vs. +8.8±13.6 cm2, p<0.01; EAT, −7.3±8.3 vs. +8.7±8.8 cm3, p<0.01). Moreover, the change in the AVAT volume negatively correlated with the change in EPA (r=−0.58, p<0.01) and EPA/AA levels (r=−0.53, p<0.01). A similar negative correlation in these parameters was also observed for the EAT volume. Conclusions: Oral intake of purified EPA appears to be associated with reductions in EAT and AVAT volumes.

The euryhaline mysid Neomysis awatschensis occurs widely in estuaries and brackish lakes in Japan. Although N. awatschensis may serve as an essential energy channel to higher trophic levels, its feeding ecology has been studied only in sheltered and desalinated Lake Kasumigaura. To determine major food sources for N. awatschensis, monthly sampling was conducted during the day along the microtidal Yura River estuary from March 2014 to July 2015. Additional sampling was conducted in May 2019 to assess diel vertical migration in relation to feeding. Microscopic examinations revealed that benthic diatoms (e.g. Bacillaria paxillifer and Navicula spp.) dominated in the stomach irrespective of developmental stage, diel cycle, or season. Stable carbon and nitrogen isotope ratios in N. awatschensis and its potential food sources indicated great contributions to the diet of N. awatschensis from benthic microalgae (mainly benthic diatoms) in 2014 and from particulate organic matter (mainly phytoplankton) in 2015. Although N. awatschensis always concentrated close to the bottom in 2019, diel vertical migration might have happened in 2015, when fresh water occupied the whole estuary possibly due to river mouth clogging. Under the stagnant and oligohaline conditions, N. awatschensis could have swum up into the water column and fed on phytoplankton at night in 2015. This hypothesis may resolve the apparent contradiction between the microscopy and stable isotope analysis in 2015. In the Yura River estuary, N. awatschensis feeds primarily on benthic diatoms, although it can utilize phytoplankton flexibly in response to prevailing environmental conditions.

Background:The J-RHYTHM Registry 2 was a multicenter, prospective observational study that extended the follow-up period of the J-RHYTHM Registry in order to investigate long-term outcomes and effects of non-vitamin K antagonist oral anticoagulants (NOACs) in Japanese patients with atrial fibrillation (AF).Methods and Results:Among 6,616 patients with nonvalvular AF (NVAF) (men 71.0%, 69.7±9.9 years, CHADS2score 1.7±1.2), event rates were compared among patients receiving warfarin (n=3,964), NOACs (n=923), and no anticoagulation therapy (No-OAC, n=753) at the end of follow-up, except for 976 patients lacking anticoagulant data. During the 5-year follow-up period, thromboembolism occurred in 196 (4.9%), 19 (2.1%), and 45 (6.0%) patients, respectively; major hemorrhage in 233 (5.9%), 22 (2.4%), and 36 (4.8%); all-cause death in 230 (5.8%), 13 (1.4%), and 105 (13.9%), (P<0.001 for each). After adjusting for the components of the CHA2DS2-VASc score and antiplatelet drug use, the odds ratio (OR) in the Warfarin group was significantly lower for all-cause death compared with that in the No-OAC group (OR 0.30, 95% confidence interval [CI] 0.23–0.39, P<0.001), whereas ORs in the NOACs group were significantly lower for all events (OR 0.42, 95% CI 0.24–0.74, P=0.003 for thromboembolism; OR 0.53, 95% CI 0.31–0.93, P=0.027 for major hemorrhage; and OR 0.10, 95% CI 0.06–0.18, P<0.001 for all-cause death, respectively).Conclusions:NOACs could be beneficial for reducing event rates of all types in Japanese NVAF patients.

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.

Background:To clarify the effects of warfarin therapy in very old patients with non-valvular atrial fibrillation (NVAF), a post-hoc analysis was performed using the data of the J-RHYTHM Registry.Methods and Results:A consecutive series of AF outpatients was enrolled from 158 institutions. Of 7,937 patients, 7,406 with NVAF (men, 70.8%; 69.8±10.0 years) were followed for 2 years or until an event occurred. Patients were divided into 3 age groups (<70, 70–84, and ≥85 years) and 5 subgroups according to international normalized ratio (INR; <1.6, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0). Prevalence of female sex, permanent AF, hypertension, coronary artery disease, heart failure, and history of ischemic stroke/transient ischemic attack was higher in the older groups. In the oldest group, 79.7% of patients received warfarin and their time in therapeutic range, using the Japanese target INR of 1.6–2.6, was 67.1%. Rate of thromboembolic events was lower in the age groups <70 and 70–84 years (P=0.027 and P<0.001, respectively) for patients receiving warfarin compared with those who were not. In the oldest group, the rate of thromboembolism plus major hemorrhage was lower at INR 1.6–2.59.Conclusions:Warfarin could have beneficial effects even in very old NVAF patients if INR is kept between 1.6 and 2.59.

Background:Because the current Japanese guideline recommends CHADS2score-based risk stratification in nonvalvular atrial fibrillation (NVAF) patients and does not list female sex as a risk for thromboembolic events, we designed the present study to compare the CHA2DS2-VASc and CHA2DS2-VA scores in the J-RHYTHM Registry.Methods and Results:We prospectively assessed the incidence of thromboembolic events for 2 years in 997 NVAF patients without warfarin treatment (age 68±12 years, 294 females). The predictive value of the CHA2DS2-VASc and CHA2DS2-VA scores for thromboembolic events was evaluated by c-statistic difference and net reclassification improvement (NRI). Thromboembolic events occurred in 7/294 females (1.2%/year) and 23/703 males (1.6%/year) (odds ratio 0.72 for female to male, 95% confidence interval (CI) 0.28–1.62, P=0.44). No sex difference was found in patient groups stratified by CHA2DS2-VASc and CHA2DS2-VA scores. There were significant c-statistic difference (0.029, Z=2.3, P=0.02) and NRI (0.11, 95% CI 0.01–0.20, P=0.02), with the CHA2DS2-VA score being superior to the CHA2DS2-VASc score. In patients with CHA2DS2-VASc scores 0 and 1 (n=374), there were markedly significant c-statistic difference (0.053, Z=6.6, P<0.0001) and NRI (0.11, 95% CI 0.07–0.14, P<0.0001), again supporting superiority of CHA2DS2-VA to CHA2DS2-VASc score.Conclusions:In Japanese NVAF patients, the CHA2DS2-VA score, a risk scoring system excluding female sex from CHA2DS2-VASc, may be more useful in risk stratification for thromboembolic events than CHA2DS2-VASc score, especially in identifying truly low-risk patients.

Background:It is unclear whether renal dysfunction affects warfarin control in patients with non-valvular atrial fibrillation (NVAF).Methods and Results:Using a dataset from the J-RHYTHM Registry, time in therapeutic range (TTR) of the international normalized ratio (INR) of prothrombin time, and creatinine clearance (CrCl) were determined in elderly patients aged ≥70 years. Target INR values were 1.6–2.6 following Japanese guidelines. Incidences of thromboembolism, major hemorrhage, and all-cause death were determined over 2 years. Of 7,406 NVAF patients enrolled in the registry, 2,782 elderly patients (mean age, 75 years) had data for CrCl measured at baseline and TTR. TTR values were lower in the lower CrCl groups (P<0.001 for trend). CrCl <30 mL/min was independently associated with TTR <65% (odds ratio, 1.49; 95% confidence interval, 1.13–1.95; P=0.004). In the multivariate analysis, TTR <65% was independently associated with thromboembolism (hazard ratio, 2.26; 95% confidence interval, 1.37–3.72; P=0.001), but CrCl was not (CrCl <30 mL/min, 1.68, 0.41–6.85, P=0.473). However, CrCl <30 mL/min and TTR <65% were independently associated with all-cause death (5.32, 1.56–18.18, P=0.008 and 1.60, 1.07–2.38, P=0.022, respectively) and the composite event (thromboembolism, major hemorrhage and all-cause death) (2.03, 1.10–3.76, P=0.024 and 1.58, 1.22–2.04, P=0.001, respectively).Conclusions:Elderly NVAF patients with renal dysfunction had poor warfarin control, which was associated with higher risk of thromboembolism and all-cause death.

Background: Recent European guidelines recommended the CHA2DS2-VASc score for thromboembolic and the HAS-BLED score for bleeding risk stratifications. We validated these scores in 7,384 Japanese patients with nonvalvular atrial fibrillation (NVAF) enrolled in the J-RHYTHM Registry. Methods and Results: Of the study cohort, 6,387 patients taking warfarin and the other 997 not taking warfarin were prospectively examined for 2 years. Thromboembolic and major bleeding risks were stratified by modified CHA2DS2-VASc (mCHA2DS2-VASc) and HAS-BLED (mHAS-BLED) scores, respectively. Of the patients with mCHA2DS2-VASc score 0, 1, and ≥2, thromboembolism occurred in 2/141 (0.7%/year), 4/233 (0.9%/year), and 24/623 (1.9%/year), respectively, in the non-warfarin group, and in 1/346 (0.1%/year, P=0.19 vs. non-warfarin), 4/912 (0.2%/year, P=0.05), and 92/5,129 (0.9%/year, P=0.0005), respectively, in the warfarin group. When female sex was excluded from the score, thromboembolism occurred in 2/180 patients (0.6%/year), 5/245 (1.0%/year), and 23/572 (1.6%/year), respectively, in the non-warfarin group, and in 1/422 (0.1%/year, P=0.20 vs. non-warfarin), 5/1,096 (0.2%/year, P=0.02), and 91/4,869 (0.9%/year, P=0.0005), respectively, in the warfarin group. Patients with mHAS-BLED scores ≥3 were at high risk for major bleeding irrespective of warfarin treatment (1.3 and 2.6%/year in the non-warfarin and warfarin groups, respectively). Conclusions: In Japanese NVAF patients, the mCHA2DS2-VASc score is useful for identifying patients at truly low risk of thromboembolism. Female sex may be excluded as a risk from the score. mHAS-BLED score ≥3 is useful for identifying patients at high risk of major bleeding. (Circ J 2014; 78: 1593–1599)

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.

Aim: Epicardial adipose tissue (EAT) is a pathogenic fat depot that may be associated with coronary atherosclerosis and cardiovascular events. Because eicosapentaenoic acid (EPA) has been reported to exert cardiovascular protective effects, we aimed to assess the effects of EPA on the volume of visceral adipose tissue, including EAT and abdominal visceral adipose tissue (AVAT), using multislice computed tomography (CT). Methods: In 30 patients with coronary artery diseases (9 women; mean age, 67.2±5.4 years), EAT and AVAT volumes were compared between the control group (n=15, conventional therapy) and the EPA group (n=15, conventional therapy plus purified EPA 1800 mg/day) during a six-month period. EAT was defined as any pixel that had CT attenuation of -150 to -30 Hounsfield units (HU) within the pericardial sac. Results: After the six-month follow-up, the serum EPA level increased from 59.9±18.8 to 177.2± 3.3 μg/mL in the EPA group (p<0.01), but no increase was noted in the control group. Similarly, the EPA/arachidonic acid (AA) ratio increased from 0.39±0.12 to 1.22±0.28 in the EPA group (p<0.01), with no significant increase in the control group. The AVAT and EAT volumes decreased in the EPA group but were unchanged in the control group (AVAT, −11.6±17.0 vs. +8.8±13.6 cm2, p<0.01; EAT, −7.3±8.3 vs. +8.7±8.8 cm3, p<0.01). Moreover, the change in the AVAT volume negatively correlated with the change in EPA (r=−0.58, p<0.01) and EPA/AA levels (r=−0.53, p<0.01). A similar negative correlation in these parameters was also observed for the EAT volume. Conclusions: Oral intake of purified EPA appears to be associated with reductions in EAT and AVAT volumes.

Purpose: To evaluate the causes of temporomandibular disorder (TMD) by examining the relationships between 3 major TMD symptoms, parafunction, and stress, a questionnaire survey was performed during dental examinations in corporations.Methods: The survey was performed using 6 questions on the following topics: 1. Trismus; 2. Joint noise; 3. Pain; 4. Clenching in the daytime; 5. Nocturnal bruxism; and 6. Stress.There were 3,225 subjects, 2,809 males and 416 females and the mean age of the subjects was 40.12 years. The relationships between questions 1 to 5 and question 6 were examined by the chi-square test.Results: There were significant correlations (question 1, p=0.001; questions 2-5, p<0.001).Conclusion: Clearly, there was an influence of psychological factors, such as stress, on TMD, and such factors were considered to play important roles in its etiology, progression, and treatment. The results of this study suggest that well-controlled studies of TMD are necessary.

Background:The incidence rate of ischemic stroke in Japanese non-valvular atrial fibrillation (NVAF) patients without anticoagulation therapy remains unclear.Methods and Results:We performed a pooled analysis of 3,588 patients from the Shinken Database (n=1,099), J-RHYTHM Registry (n=1,002), and Fushimi AF Registry (n=1,487) to determine the incidence rate of ischemic stroke in Japanese NVAF patients without anticoagulation therapy. Average patient age was 68.1 years. During the follow-up period (total, 5,188 person-years; average, 1.4 years), 69 patients suffered from ischemic stroke (13.3 per 1,000 person-years; 95% confidence intervals [CI]: 10.5–16.8). The incidence rates of ischemic stroke were 5.4, 9.3, and 24.7 per 1,000 person-years and 5.3, 5.5, and 18.4 per 1,000 person-years in patients with low (0), intermediate (1), and high (≥2) CHADS2 and CHA2DS2-VASc scores, respectively. History of ischemic stroke or transient ischemic attack (hazard ratio [HR], 3.25; 95% CI: 1.86–5.67), age ≥75 years (HR, 2.31; 95% CI: 1.18–4.52), and hypertension (HR, 1.69; 95% CI: 1.01–2.86) were independent risk factors for ischemic stroke.Conclusions:A low incidence rate of ischemic stroke was observed in Japanese NVAF patients except for those with CHADS2 score ≥2. In this pooled analysis, history of ischemic stroke or transient ischemic attack, advanced age, and hypertension were identified as independent risk factors for ischemic stroke.

We designed a seismic intensity meter and a data collection network for use in the Philippines. The station unit deployed consists of a digital acceleration sensor with 0.1 gal noise and a compact Microsoft Windows PC. The station unit, which is designed to be installed in local government offices, calculates values every 10 seconds for the PEIS (Philippine Earthquake Intensity Scale), and these values are shown on a display and transmitted to the main PHIVOLCS office over the Internet. One hundred units to be deployed throughout the country are now being distributed to offices.
