In 1995, an experimental examination consisting of an Objective Structured Clinical Examination (OSCE) and multiple choice questions (MCQs) regarding physical examinations was held by a research group conducted by Prof. Saichi HOSODA, Tokyo Women's Medical College, and subsidized by the Ministry of Health and Welfare.
Sixty-two fifth-year students (volunteers) were assessed their skills in interviewing, physical examination, and cardio-pulmonary resuscitation at five stations, by faculty members from several universities using detailed checklists. The group found: 1) No correlation was observed between OSCE and MCQ tests, 2) Two-ranked checklists improved the reliability of the evaluation, 3) Examinees showed great interest in the method and expressed a hope that OSCE might be introduced into undergraduate education. OSCE will encourage the learning activities of students.

An Elderly Health and Fitness Promotion Program was carried out in the 32 on areas of Ichihazama Town (now Kurihara City), Miyagi Prefecture to promote the health of the elderly population by making as many townspeople as possible aware of their health and fitness levels, and develop active lifestyles. We evaluated the effectiveness of this program on the basis of the results during the past 4 years.In 2001, the Elderly Health and Fitness Promotion Program was started in each of the town's 32 administration areas. The number of participants continued to increase until it exceeded 600 in 2004, with increases in the percentages of males, those aged 80 years or above, and those withlimited ADL among the participants. While the results of fitness tests varied widely and were very low in some participants, changes in the fitness level were small in regular participants.

We reviewed the clinical course of 127 patients who underwent treatment for atherosclerotic disease between June 1993 and January 2001. There were 108 men and 19 women. The ages ranged from 49 to 88 years with a median age of 71.2 at the time of the first operation. Major risk factors included ischemic heart disease (21%) and diabetes mellitus (20%). Ninety-five percent of the patients were followed successfully and the follow-up period ranged from 0 to 90 months with a mean of 33 months. Two patients died perioperatively due to myocardial infarction. There were 29 late deaths. The overall actuarial survival rate was 69.7% at 5 years. The 5-year actuarial survival rate and the mean survival time for men and women were 71.6%, 66.1 months and 62.3%, 58.9 months. The 5-year late survival rate and the mean survival time for patients with and without ischemic heart disease were 57.0%, 57.4 months and 74.2%, 68.5 months. The differences were not statistically significant. The 5-year late survival rate and the mean survival time for patients with and without diabetes mellitus were 65.5%, 59.1 months and 70.9%, 67.4 months. The differences were not statistically significant. Amputation was performed in 7 patients, the actuarial survival rate at 1 year and the mean survival time were 42.9%, 7.1 months for patients with amputation, and 93.0%, 69.5 months without amputation (p<0.01).

OBJECTIVETo analyze the upstream region of radiation-induced junB gene.

METHODSFour plasmids containing 250 bp, 590 bp, 900 bp and 1650 bp, and CAT reporter gene were constructed separately and introduced to L8704 cells. The cells were irradiated with 2 Gy X-rays and incubated at different intervals. Total RNA was extracted from the cells and fluctuation of the CAT mRNA level was assessed by the RNA ratio of CAT/beta-actin measured by quantitative Northern blot hybridization.

RESULTSCAT mRNA expression containing 900 bp and 1560 bp junB promoter remarkably and rapidly increased, and reached its peak 30 min after 2 Gy X-ray irradiation.

CONCLUSIONS590-900 bp fragments located in the upstream region of junB gene play an important role in the early process of cells against radiation.

　　Introduction: Reimbursement for breathing care services was started with the revision of the nation's medical service fee system in 2010. Our hospital was not properly equipped in the light of certain standards governing facilities. Nonetheless, we started giving instructions to nurses on how to check the respirator at work. In addition to the on-the-job training, we are engaged in educational activity and information gathering. Out team comprises clinical engineers, physical therapists and registered nurses. They are all certified respiratory therapists. We hereby report our activities and refer to future problems.　　Activities: 1. Safety checks of respirators while in use. 2. Respiratory rehabilitation during hemodialysis. 3. Respirator-related workshops. 4. Review of accidents.　　Results: 1. It has become easier to discover potential problems and meet them at once. This is because our team is made up of different specialists, each used to looking at things differently. 2. Being constantly on the alert for any indication of a trouble ensures safety during breathing rehabilitation. 3. The number of accidents during 2012 decreased from 2011.　　Future: We think that since “safety management” is the center piece of our activity, our team ought to be recognized as an official organization of the hospital.

The purpose of this study was to determine daily steps corresponding to the reference value for the quantity of Physical Activity and Exercise for Health Promotion 2006 (23 METs·h/wk) considering non-locomotive activities. Two hundred and thirty one men and 224 women wore a tri-axial accelerometer for two weeks. We analyzed the data in each age group (young (less than 40 years), middle-aged (40 to 59 years), and elderly (60 years or more) groups), also. There were significant relationships between daily steps and locomotive activity (r = 0.762 to 0.820, p < 0.001) and total (locomotive and non-locomotive) physical activity (r = 0.706 to 0.824, p < 0.001) with intensity of 3 METs or more in all groups. The daily steps corresponding to 23 METs·h/wk, calculated using regression lines between the daily steps and total physical activities with intensity of 3 METs or more in men and women were 6,534 steps/d and 6,119 steps/d. On the other hand, the daily steps corresponding to 23 METs·h/wk, calculated using regression lines between the daily steps and locomotive activities with intensity of 3 METs or more in men and women were 7,888 steps/d and 8,584 steps/d. These results suggest that non-locomotive activity should also be taken into consideration in the case of assessment of a daily physical activity.

The purpose of this study was to examine the risk factors of stress fractures in terms of training distance and intensity in young male Japanese high school long-distance runners. Nine hundred and twenty-five runners from high schools, colleges, and work teams responded to our questionnaire. Our analysis of the questionnaire found that the onset rates of stress fractures in males were 25.0%, 40.2%, and 55.3% in high school runners, collegiate runners, and work team runners, respectively, suggesting that young Japanese long-distance runners are more likely to suffer from stress fractures than European and American runners. Stress fractures occurred in male high school and collegiate runners after training that had increased running distance (24.7% and 33.1%, respectively) or running intensity (17.0% and 9.6%), or both increased running distance and increased running intensity (29.8% and 34.6%), suggesting that an increase in running distance at moderate intensity might be a major risk factor in stress fractures in young male long-distance runners. Data from college and work team runners that ran all three years of high school show that stress fractures are most likely to occur in May of the high school freshman year. These results suggested a need to reconsider training programs for freshmen to prevent stress fractures in young runners.

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.

Background/Aims: Intestinal Behçet disease is typically associated with ileocecal punched-out ulcers and significant morbidity and mortality. Intestinal ultrasound is a noninvasive imaging technique for disease monitoring. However, no previous reports have compared intestinal ultrasound with endoscopic ulcer activity or histopathological findings for intestinal Behçet disease. We evaluated the usefulness of intestinal ultrasound for assessing the activity of ileocecal ulcers in intestinal Behçet disease. Methods: We retrospectively compared intestinal ultrasound findings with 73 corresponding endoscopic images and 6 resected specimens. The intestinal ultrasound findings were assessed for 7 parameters (bowel wall thickness, vascularity [evaluated using the modified Limberg score with color Doppler], bowel wall stratification, white-plaque sign [strong hyperechogenic lines or spots], mesenteric lymphadenopathy, extramural phlegmons, and fistulas), and endoscopic ulcer activity was classified into active, healing, and scar stages. Histopathological findings were evaluated by consensus among experienced pathologists. Results: Bowel wall thickness (P< 0.001), vascularity (P< 0.001), loss of bowel wall stratification (P= 0.015), and white-plague sign (P= 0.013) were significantly exacerbated in the endoscopic active ulcer stage. Receiver operating characteristic curve analysis revealed that a bowel wall thickness of > 5.5 mm (sensitivity 89.7%, specificity 85.3%) was potentially useful for detecting active lesions. When compared with histopathological findings, an increase in bowel wall thickness reflected the ulcer marginal ridge, and the white-plaque sign reflected the ulcer bottom. Conclusions Intestinal ultrasound is useful for monitoring intestinal ulcer activity in intestinal Behçet disease.

Objective: To describe the treatment patterns and time to next treatment (TTNT) in newly diagnosed multiple myeloma patients (MM) using a large-scale claims database in Japan.Design: Cohort studyMethods: The patients with newly diagnosed MM from 2008 to 2015 were classified into two groups: age <65 years, and age ≥65 years. Specific regimens and general regimens were identified with a complex algorithm considering interval of no therapy, additional and discontinued agents. Correspondingly, TTNT between the first- and second-line were measured among non-transplant patients with Kaplan-Meier method.Results: A total of 425 patients were eligible to participate in the analysis. The most common regimen for the treatment of MM was bortezomib-based regimens (52.9％ in the first-line, 28.2％ in later lines), followed by melphalan-prednisolone (27.1％ in the first-line, 12.9％ in later lines) and lenalidomide-based regimens (4.7％ in the first-line, 26.1％ in later lines). TTNT between the first- and second-line was 11.4 months and was seen to vary greatly with each regimen. A statistically longer TTNT was observed in subgroups of patients aged 65 years or over compared with patients aged younger than 65 years, but no statistical difference was found between conventional therapy and novel therapy.Conclusion: Based on the data from the study, patients with MM were commonly treated with novel agent-based regimens, especially bortezomib-based regimens. Between the first- and second-line therapies a relatively short TTNT was observed, indicating that therapies in clinical practice poorly complied with treatment guidelines.
