A study was conducted to develop prediction equations for cardiorespiratory fitness (maximal oxygen uptake : VO2max and oxygen uptake at anaerobic threshold : VO2AT) in Japanese adult men and women. Eighty-three healthy men and 86 healthy women, aged 20-64 years (41.1±13.5 and 41.5±13.5, respectively), were recruited as subjects. Mean (±SD) of VO2max and VO2AT measured during a cycling test were 37.2±6.4 and 20.5±4.7 ml/kg/min, respectively, in men and 32.7±7.3 and 17.8±4.1 ml/kg/min, respectively, in women. In this study 36 kinds of equations applicable to each sex were developed using all the subjects (n=169) . These equations consisted of independent variables such as work rate divided by body weight (W/Wt), age and body fat percentage (%Fat), which were signficantly correlated with measured VO2max and VO2AT. Multiple correlation coefficients (R) and standard errors of estimate (SEE) of the equations ranged from 0.641 to 0.830 (P<0.05) and from 3.66 to 4.98 ml/kg/min, respectively, for VO2max and from 0.661 to 0.815 (P<0.05) and from 2.77 to 3.20 ml/kg/min, respectively, for VO2AT. Reliability coefficients (r) between the first and second tests were 0.911 in men and 0.873 in women for VO2max, and 0.869 in men and 0.770 in women for VO2AT, all of which were statistically significant (P<0.05) . It is concluded that the equations developed in the present study have the merits of simplicity, economy, accuracy and reliability. Furthermore, from the viewpoint of safety and convenience, the following prediction equations are recommended.

OBJECTIVE:
This study aims to examine the awareness and ability of health care providers to cope with language barriers at medical facilities in Hyogo Prefecture, Japan, and to clarify the issues concerning health care for foreigners.
METHODS:
In total, 2100 copies of self-report questionnaires on issues of health care for foreigners were mailed to health care providers of 352 hospitals in Hyogo. The survey was conducted from February to March 2010.
RESULTS:
The response rate of medical facilities was 21.6% (76/352), whereas that of the health care providers was 15.2% (320/2100). Approximately 10% hospitals handled foreign patients at least once per month, and they dealt with patients using several languages, including English, Chinese, Korean, and others. The providers' main issue was communication with their foreign patients. The documents and booklets for guidance regarding some health care procedures at the hospitals were also poorly prepared. It is therefore exceedingly necessary for hospitals to provide common documents in different languages; moreover, the government or local authorities should arrange for public medical interpretation services.
DISCUSSION:
Medical facilities in Hyogo have been struggling to improve their linguistic capabilities, and it is difficult to indicate whether public organizations concerned with medical interpretation are being recognized. Efforts on the part of medical facilities and local and national governments, as well as cooperation of nonprofit organizations, are immensely essential to resolve the issue of multilingual health care. This survey suggests that to help people with diverse languages, the health care system in Japan should be improved rapidly, particularly with regard to the establishment of licensed professional medical interpreters.

The purpose of this study was to elucidate the effects of whole-body vibration training (WBVT) on knee function and physical performance in middle-aged and older Japanese women who suffered from knee osteoarthritis (OA) and knee pain. Thirty-eight middle-aged and older Japanese women (aged 50-73 years) with knee OA and knee pain were divided into two groups: (1) a WBVT group (n = 29) engaging in WBVT 3 times a week for 8 weeks, and (2) a control group (C group, n = 9) performing exercises at home. The WBVT program consisted of a warm-up, strength training mainly of the quadriceps and their surrounding muscles and cool-down exercises. In the WBVT group, there were no dropouts, and there were significant improvements in the physical function (Cohen’s d = 0.28) and total score (Cohen’s d = 0.25) of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). There were also statistically significant improvements in all lower-extremity function tests (5-times sit-to-stand, timed up and go, standing time from a long sitting position, sit and reach, 4-way choice reaction time; Cohen’s d = 0.34-1.24). The item that changed significantly in the C group, however, was only the sit and reach (Cohen’s d = 0.52). In addition, all items in the Japanese Orthopaedic Association Score (JOA score) improved significantly (Cohen’s d = 0.63-0.67) in the WBVT group. In conclusion, the 8-week WBVT program can safely improve knee function and physical performance in middle-aged and older Japanese women who suffer from knee OA and knee pain.

In a clinical introductory program, each group of 9 fifth-year medical students rotated through 9 courses every 2 weeks. In each class, students evaluated the instructional abilities of the faculty. Eighty-two students answered 7 questions on a 5-point scale immediately after each class was completed. Because the questionnaire also served as a record of attendance, responses were obtained from all students who attended. Overall satisfaction was correlated most strongly with teaching skills, followed by contents of the class to achieve goals and the level of difficulty. The evaluation of faculty's instructional abilities by students can provide valuable information on areas to improve so that students can be educated more effbctively and with greater satisfaction.

The purpose of this study was to examine the effects of 9 weeks of resistance training, with and without static acceleration training (AT), on participants' lower-limb muscle strength, power, and physical function. Healthy participants (19 men and 28 women), aged 65-75 years, were assigned to a static AT group (AT, n = 31) or a non-AT control group (C, n = 16). The AT group and the C group trained three times/week for 9 weeks. The AT group performed unloaded static AT and low-intensity aerobic activity. The C group performed dynamic weight-bearing resistance training without whole-body vibration and the same aerobic activity as the AT group. We collected and analyzed data from 45 participants (AT = 30, C = 15) who completed pre- and post-tests. There was no significant Group × Time interaction on any measurements of lower-limb muscle strength, power, or physical function. Significant time effects were observed in the following tests:isokinetic knee extensor and flexor peak torque, 5-time sit-to-stand, usual gait speed, timed up and go, standing time from a long sitting position, and sit and reach. All of these 7 variables showed positive changes. These results suggest that static AT is a suitable training method having approximately the same efficiency as conventional, weight-bearing, dynamic resistance training for improving lower-limb muscle strength and power, mobility, and flexibility in community-dwelling Japanese older adults.

This study examined relationships between physical activity and sleep relative to leisure-time, household, and occupational physical activity in community-dwelling, older adults. From 3,000 randomly chosen community-dwelling, adults, aged 65-85 years, we recruited 509 eligible subjects (mean age 73.2 ± 5.1 years). We assessed nocturnal sleep duration, sleep onset latency and subjective sleep quality over the previous month through a questionnaire. Physical Activity Scale for the Elderly was used to assess leisure-time, household, and occupational physical activity. Items pertaining to sleep were expressed as dichotomous variables (good/poor), and each physical activity score was divided into two categories based on activity level. To investigate the relationship between sleep (dependent variable) and physical activity (independent variable), we used a logistic regression analysis, controlling for age, gender, living arrangement, depressive symptoms, and cognitive function. Prolonged sleep latency was significantly related to no participation in low intensity exercise (OR 2.14; 95% CI 1.42-3.21) and muscle strength exercise (OR 1.99; 95% CI 1.06-3.74). Our data suggest that not participating in low intensity exercise or muscle strength exercise may be associated with difficulty initiating sleep in older adults.

Objective: Similarity of drug names is one factor of dispensing incidents. The aim of this study was to survey the relation between sensual similarities of drug names and the occurrence of taking errors for pharmacists who actually prepare medicine.
Methods: A pair of drugs (15 incident pairs and 104 control pairs) was displayed on a computer screen at random. The subject’s task was to determine the sensual similarity of them. Thirteen pharmacists who prepared these pairs and caused their incidents participated in the experiment.
Results: The result showed that the sensual similarity of drug names of incident pairs was found to be highly significant in comparison to one of the control pairs [p=0.026]. However, the similarity in incident pairs is not necessarily high. It was suggested that the similarity of drug name was not the only factor of taking error. Multiple linear regression analyses of the sensual similarity in control pairs were performed, in which 10 variables were reported as quantitative indicators of similarity of drug name and were able to be measured on the internet. The correlation was good [R2=0.828]. However, this regression model was not useful when adjusting to incident pairs. In incident pairs, the similarity value calculated by the regression model was lower than the measured sensual similarity.
Conclusion: The result suggested that measured sensual similarity includes other risk factors of taking error, such as appearance similarity and/or efficacy similarity and/or short distance arrangement. It seemed that the pharmacist’s ability complicated the factor of taking error.

Background and Purpose : Many cases of amnesia caused by thalamic hemorrhage involve anterior nucleus hemorrhage, dorsomedial nucleus hemorrhage, and intraventricular rupture. In the present study, intraventricular rupture was studied with a focus on cases with hematoma compression at the fornix. Methods : Of 116 patients with thalamic hemorrhage admitted to our hospital, 50 patients aged <70 years who had hemorrhage during their first stroke confined to the thalamus, internal capsule, and corona radiata, and who neither developed hydrocephalus nor showed dementia prior to onset were investigated. Thalamic hemorrhages were classified by CT findings and the extent of intraventricular rupture. Memory was studied by the FIM memory scores on admission and discharge. Results and Conclusion : Patients with dorsomedial nucleus hemorrhage showed no tendency toward amnesia and were equivalent to patients with posterolateral nucleus hemorrhage, which does not usually result in amnesia on its own. Of the 30 patients with posterolateral nucleus hemorrhage, a high degree of amnesia was observed in the 18 with intraventricular rupture. A high proportion of patients with dorsomedial nucleus hemorrhage experienced intraventricular rupture (5 of 6 patients). Equivalent degrees of amnesia were observed in patients with intraventricular rupture with dorsomedial nucleus hemorrhage and those with posterolateral nucleus hemorrhage. The present findings in conjunction with the fact that amnesia in thalamic hemorrhage involves episodic memory impairment suggest that amnesia in patients with dorsomedial or posterolateral nucleus hemorrhage or with intraventricular rupture does not stem from damage to the dorsomedial nucleus, which is part of the Yakovlev circuit involved in emotional memory. Instead, the primary cause appears to be the effects of intraventricular rupture on the Papez circuit surrounding the lateral ventricle and foramen of Monro.

Objective: We conducted a meta-analysis on the suppressive effect of resistant maltodextrin on post-prandial blood glucose elevation, which is approved in Japan as food for specified health use, and the following is allowed to be indicated on the label “it is suitable for consumption by those who are concerned about their post-prandial blood glucose levels because the absorption of sugars is abated by the action of dietary fiber (resistant maltodextrin).”
Method: Our literature search covered Ichushi-Web (Japan Medical Abstracts Society), Japan Science and Technology Information Aggregator, Electronic (J-stage), Google Scholar, and PubMed databases and extracted English and Japanese publications on randomized, double-blind, controlled studies comparing resistant maltodextrin and a control in Japanese subjects for the reduction of areas under the blood glucose response curves at 30, 60, and 120 min after eating as an efficacy index.
Result: Among these publications, four articles with a Jadad score (an assessment of the quality of randomized controlled studies) of ≥ 3 were included in the meta-analysis. Significant inhibitory effects were confirmed from areas under the blood glucose response curves at 30, 60, and 120 min after eating in the meta-analysis that was performed to evaluate the effects of resistant maltodextrin on post-prandial blood glucose elevation in Japanese individuals.
Conclusion: However, we were not able to test for publication bias because the number of extracted publications was small, and thus, additional research and case studies are warranted.
