Background: The center for international relations was established in 2007 and it has organized a program for accepting international students for short periods since 2009 to enhance internationalization at the medical school.

Methods: The number of inbound and outbound students, and the number of overseas medical schools with an Academic Agreement and a Memorandum of Understanding with our institution from 2008 to 2013 were counted, and the relevant achievements were evaluated.

Results: The number of inbound students increased from 0 in 2008 to 14 in 2013, and the number of outbound students also increased from 1 in 2008 to 12 in 2013. The number of overseas medical schools with an Academic Agreement and a Memorandum of Understanding also increased from 1 to 3. The number of scholarship applications to go overseas also increased from 2 to 12.

Discussion: Organizing a well-established program for inbound students probably contributed to developing the international environment within the school for both inbound and outbound students, and to enhancing discussion of student exchange with potential partner universities. The center for international relations has functioned as a hub for the students and relevant departments by centralizing information, which has markedly communication improved.

Two major definitions of metabolic syndrome have been proposed. One focuses on the accumulation of risk factors, a measure used by the American Heart Association (AHA) and the National Heart, Lung, and Blood Institute (NHLBI); the other focuses on abdominal obesity, a measure used by the International Diabetes Federation (IDF) and the Japanese government. The latter definition takes waist circumference (WC) into consideration as an obligatory component, whereas the former does not. In 2009, the IDF, NHLBI, AHA, and other organizations attempted to unify these criteria; as a result, WC is no longer an obligatory component of those systems, while it remains obligatory in the Japanese criteria. In 2008, a new Japanese cardiovascular screening and education system focused on metabolic syndrome was launched. People undergoing screening are classified into three groups according to the presence of abdominal obesity and the number of metabolic risk factors, and receive health educational support from insurers. This system has yielded several beneficial outcomes: the visibility of metabolic syndrome at the population level has drastically improved; preventive measures have been directed toward metabolic syndrome, which is expected to become more prevalent in future generations; and a post-screening education system has been established. However, several problems with the current system have been identified and are under debate. In this review, we discuss topics related to metabolic syndrome, including (1) the Japanese criteria for metabolic syndrome; (2) metabolic syndrome and the universal health screening and education system; and (3) recent debates about Japanese criteria for metabolic syndrome.

Westernization of lifestyles among Japanese, in particular among young generations, is a matter of concern for future increase in coronary heart disease. We surveyed a total of 349 male university students to examine changes in lifestyles and coronary risk factors in campus life. We compared dietary habits and serum fatty acid compositions as well as other coronary risk characteristics between freshmen (n=171) and fourth-year (senior) students (n=178). Serum fatty acid compositions and dietary intakes of selected foods as well as serum lipids, blood pressures and physical characteristics were examined at the 1996 and 1997 annual health examinations. Compared to freshmen, senior students had a lower frequency of fish, vegetable, milk and egg intake, and a higher frequency of oil and fat intake. The proportions of serum saturated and monounsaturated fatty acids were significantly higher among senior students than among freshmen, whereas the proportion of serum polyunsaturated fatty acids was significantly lower among senior students than among freshmen. Senior students also had higher systolic and diastolic blood pressures, percent body fat, smoking rate and alcohol usage than freshmen. Mean body weight and mean body mass index were not different between the two groups. Senior students generally showed Westernized dietary habits and higher coronary risk profiles than freshmen as indicated by the change of serum fatty acid compositions. Modification of these dietary habits and lifestyles may be important for the prevention of future CHD among Japanese young adults.

To examine the relationships between anger expression and blood pressure (BP) levels and their effect modification by stress coping behaviors, the authors analyzed data from a cross−sectional study of 790 Japanese male workers aged 20−60 years. We used the Spielberger anger expression scales to measure anger−out, anger−in, and anger−control. Relationships between anger expression scales and mean systolic and diastolic BP levels were examined in the total sample and in two subgroups of high and low stress coping behaviors (low coping behavior group: having none, one, or two coping behaviors; and high coping behavior group: having three or more coping behaviors). Anger expression scales were not associated with BP levels in the total sample. Among men who reported only two or fewer coping behaviors, however, the anger−out score was significantly associated with systolic blood pressure (SBP) levels while no association was found among men who reported the larger number of coping behaviors. Anger−in and anger−control were not associated with BP levels in either low or high coping behavior groups. This study suggests that male workers who do not express their anger have a higher probability of developing high BP when they have no or few stress coping behaviors.

PURPOSE: The evidence on effects of TV viewing time among premenopausal and postmenopausal women for breast cancer risk remains controversial and limited. MATERIALS AND METHODS: A prospective study encompassing 33,276 (17,568 premenopausal, and 15,708 postmenopausal) women aged 40-79 years in whom TV viewing time, menstrual, and reproductive histories were determined by a self-administered questionnaire. The follow-up was from 1988 to 2009 and hazard ratios (HRs) with 95% confidence intervals (CIs) of breast cancer incidence were calculated for longer TV viewing time in reference to shorter TV viewing time by Cox proportional hazard models. RESULTS: During 16.8-year median follow-up, we found positive associations between TV viewing time and breast cancer incidence with a borderline significant trend among total women and a significant trend among postmenopausal women. Among total women, the multivariable HRs (95% CIs) for risk of breast cancer in reference to < 1.5 hr/day of TV viewing time were 0.89 (0.59-1.34) for 1.5 to < 3.0 hr/day, 1.19 (0.82-1.74) for 3.0 to < 4.5 hr/day, and 1.45 (0.91-2.32) for ≥ 4.5 hr/day (p for trend=0.053) and among postmenopausal women, the corresponding risk estimates were 1.10 (0.42-2.88), 2.54 (1.11-5.80), and 2.37 (0.92-6.10) (p for trend=0.009), respectively. CONCLUSION: Prolonged TV viewing time was associated with increased risk of breast cancer, especially among postmenopausal women.

OBJECTIVES: This study investigated conventional cardiovascular and lifestyle risk factors affecting mortality from chronic kidney disease as the underlying cause in the general Japanese population. METHODS: We conducted an 18.8-year follow-up study of 44,792 men and 61,522 women aged 40-79 from the Japan Collaborative Cohort Study for Evaluation of Cancer Risk between 1986 and 1990. Cox proportional hazard models were used to analyze the association between risk factors and mortality from chronic kidney disease. RESULTS: During the follow-up period, 373 participants (185 men and 188 women) died from chronic kidney disease. A body mass index of ≥27.0 kg/m2 (hazard ratio [HR], 2.00; 95% confidence interval [CI], 1.19 to 3.36 for men and HR, 1.91; 95% CI, 1.19 to 3.07 for women, compared with 23.0-24.9 kg/m2), a history of hypertension (HR, 2.32; 95% CI, 1.67 to 3.22 for men and HR, 2.01; 95% CI, 1.44 to 2.81 for women) and a history of diabetes mellitus (HR, 5.21; 95% CI, 3.68 to 7.37 for men and HR, 7.10; 95% CI, 4.93 to 10.24 for women) were associated with an increased risk of mortality from chronic kidney disease in both genders. In men, smoking was also associated with an increased risk (HR, 1.91; 95% CI, 1.25 to 2.90), while current drinking (HR, 0.58; 95% CI, 0.34 to 0.98 for <23 g/day; HR, 0.48; 95% CI, 0.29 to 0.80 for 23-45 g/day and HR, 0.53; 95% CI, 0.32 to 0.86 for ≥46 g/day) and exercising ≥5 hr/wk (HR, 0.42; 95% CI, 0.18 to 0.96) were associated with a lower risk. Similar but non-significant associations for smoking and drinking were observed in women. CONCLUSIONS In addition to a history of hypertension and a history of diabetes mellitus, body mass index, smoking status, drinking status, and exercise habits were associated with the risk of mortality from chronic kidney disease.
