Objective: The purpose of this study was to investigate regional differences in the standard mortality ratio (SMR) and risk factors (including dietary habits) for stroke across the three regions of Ehime Prefecture - Toyo (east), Chuyo (central), and Nanyo (south).
Participants and methods: We obtained medical records derived from 956,979 medical examinations carried out at JA Ehime Kouseiren Medical Examination Centers between April 1994 and March 2006. We analyzed data from 132,090 subjects (Toyo - 47,654, Chuyo - 38,435, Nanyo - 46,001) who underwent their first medical examination during this period. To analyze differences between the three regions, we first calculated the SMR for stroke based on data from the Basic Residential Registers and Health Statistics Bureau. Secondly, we calculated significant differences in body mass index, systolic blood pressure (SBP), diastolic blood pressure (DBP), blood glucose (Glu), and total cholesterol (T-CHO). Thirdly, we used the Chi-square test to calculate significant differences in the percentage of subjects who consumed the following foods on a daily basis: rice, bread, eggs, fish, meat, vegetables, dairy products, and fruit juice.
Results: Despite the fact that regional differences in the SMR for stroke have been decreasing, in both men and women in Nanyo, the mean values for SBP and DBP were significantly higher and the mean value for T-CHO was significantly lower than in Toyo and Chuyo. In Nanyo, the percentage of subjects who consumed rice and fish (men and women), meat (men), and juice (women) on a daily basis was higher than in Toyo and Chuyo.
Conclusion: In Nanyo, higher SMR for stroke may be related to high SBP and DBP and low T-CHO. As background to these results, it is also thought that regional differences in dietary habits may have an influence.

Objective: In our country, the measure for the spread of the generic has been introduced over several-time as part of the moderation in health care cost plan.  However, not having related to an enough spread unlike Europe and America yet is a current state.  Then, we investigated from the view point of patients.  A detailed examination was performed for the acknowledgment level and attitude toward the generic drug.
Design and Method: The questionnaire survey was performed for the patient who used the community pharmacy for dispensing prescription.  The investigation was performed for two weeks (June and July, 2008) at the 50 drugstores in Hokkaido.  The patient attribute, source of information, and kind of the taking medicine were examined as a factor to affect decision making for generic drug substitution.
Result: The main results are as follows.  The patients who did not know generic drugs accounted 52% of the total and the patients who did not know the words called generic drugs was 16%.  This result shows that the degree of the recognition about generic drugs at that time was still low.  The information source for the patients who learned generic drugs were articles of the newspaper, a TV program, and advertising with accounted 52% of the total.  Also, the patients who prefer generic drugs in the future were 64%.  In the relationships between presence of wish for generic drugs and the source of information, the case of from the doctor, was significant (p<0.05) and the case from the pharmacist showed the tendencies of statistical significance (p=0.076).
Conclusion: From the viewpoint of medicine costs restraint in our country, it seems that the pharmacist contributes for the patient’s generic drugs selection expected positively.

Objectives: Despite the fact that the total energy intake of Japanese people has decreased, the percentage of obese people has increased.This suggests that the timing of meals is related to obesity.
The purpose of the study was to investigate the relationship between the timing of meals and obesity, based on analyses of physical measurements, serum biochemical markers, nutrient intake, and lifestyle factors in the context of Chrononutrition.
Participants and Methods: We analyzed data derived from 766 residents of Toon City (286 males and 480 females) aged 30 to 79 years who underwent detailed medical examinations between 2011 and 2013. These medical examinations included. (1) physical measurements (waist circumference, blood pressure, etc.); (2) serum biochemical markers (total cholesterol, etc.); (3) a detailed questionnaire concerning lifestyle factors such as family structure and daily habits (22 issues), exercise and eating habits (28 issues), alcohol intake and smoking habits; (4) a food frequency questionnaire based on food groups (FFQg);and (5) a questionnaire concerning the times at which meals and snacks are consumed.
Results: The values for body mass index (BMI) and waist circumference were higher for participants who ate dinner less than three hours before bedtime (<3-h group) than those who ate more than three hours before bedtime (>3-h group). The Chi-square test showed that there was a significant difference in eating habits, e.g., eating snacks, eating snacks at night, having dinner after 8 p.m., and having dinner after 9 p.m., between the <3-h group and the >3-h group.
Multiple linear regression analysis showed that skipping breakfast significantly influenced both waist circumference (β = 5.271) and BMI (β = 1.440) and that eating dinner <3-h before going to bed only influenced BMI (β = 0.581).
Conclusion: Skipping breakfast had a greater influence on both waist circumference and BMI than eating dinner <3-h before going to bed.

Objective: The Sequential Organ Failure Assessment (SOFA) score is a useful tool in defining the clinical conditions and describing the acute morbidity of patient populations with critical illness. This study was performed to assess the usefulness of the SOFA score in predicting the prognosis among cardiac or thoracic aortic postoperative patients. Methods: In total, 123 patients who entered the intensive care unit after a cardiac or thoracic aortic operation from August 2019 to December 2020 were retrospectively investigated. The SOFA score cut-off value from the admission day to postoperative day 3 calculated in the first 60 patients (derivation group) was validated in the latter 63 patients (validation group). Additionally, the Japan SCORE cut-off value calculated in the derivation group was validated in the validation group. Results: The perioperative mortality rate, in-hospital mortality rate and hospital transfer rate were 4.9, 7.3, and 13.2%, respectively. A SOFA score cut-off value of ≥7 for prediction of in-hospital mortality resulted in a sensitivity of 100% and specificity of 81% on postoperative day 2, followed by high sensitivity of 100% and specificity of 95% on postoperative day 3. A SOFA score cut-off value of ≥6 for prediction of hospital transfer resulted in a sensitivity of 57% and a specificity of 67% on postoperative day 2. Conclusion: The SOFA score on postoperative day 2 provides good discriminatory power for in-hospital mortality among cardiac or thoracic aortic postoperative patients. The SOFA scoring system could be useful for predicting short-term prognosis of patients who undergo cardiac or thoracic aortic surgery.

We herein report an extremely rare cardiac tumor of lymphatic malformation in 77-year-old man. The computed tomography (CT) demonstrated a mass from the lateral side of the left atrium to the lateral and posterior wall of the left ventricle among intrapericardial adipose tissue involving the left coronary artery. We performed partial resection of the tumor for definitive diagnosis under cardiopulmonary bypass. The histological finding was cardiac lymphatic malformation and was considered to be benign. There was no evidence of the growth of any cardiac tumor during the one-year follow up.

Objective: This study aimed to examine the relationship between mortality risk and health-related factors and sense of coherence (SOC) in a cohort study of residents from a rural area of Japan.Materials and Methods: We followed-up with 3,416 baseline respondents over 3.76 years. Residents were subdivided into three groups based on SOC score: low, middle, and high. We used the total SOC score of the low-level SOC group as the standard, and calculated the standardized mortality ratio (SMR) for the middle- and high-level SOC groups. For all three SOC groups, health-related factors were analyzed by one-way analysis of variance, and lifestyle and history were analyzed using the χ2 test. Results were also analyzed by gender and age.Results: For men in the low-level SOC group, the SMR value was defined as 1, and for men in the high-level SOC group (0.44; 95% confidence interval: 0.11–0.77), the SMR value was significantly lower. There was a statistically significant reduction in the percentage of smokers in the men in the high-level SOC group.Conclusion: In this study, high-level SOC was associated with low mortality risk. This finding was particularly pronounced in the men.

Objective: Monitoring the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants is important due to concerns regarding infectivity, transmissibility, immune evasion and disease severity. We evaluated the temporal and regional replacement of previous SARS-CoV-2 variants by the emergent strains, Alpha and Delta. Methods: We obtained the results of polymerase chain reaction screening tests for variants conducted in multiple commercial laboratories. Assuming that all previous strains would be replaced by one variant, the new variant detection rate was estimated by fitting a logistic growth model. We estimated the transmission advantage of each new variant over the pre-existing virus strains. Results: The variant with the N501Y mutation was first identified in the Kinki region in early February 2021, and by early May, it had replaced more than 90% of the previous strains. The variant with the L452R mutation was first detected in the Kanto-Koshin region in mid-May, and by early August, it comprised more than 90% of the circulating strains. Compared with pre-existing strains, the variant with the N501Y mutation showed transmission advantages of 48.2% and 40.3% in the Kanto-Koshin and Kinki regions, respectively, while the variant with the L452R mutation showed transmission advantages of 60.1% and 71.9%, respectively. Discussion In Japan, Alpha and Delta variants displayed regional differences in the replacement timing and their relative transmission advantages. Our method is efficient in monitoring and estimating changes in the proportion of variant strains in a timely manner in each region.
