[Undergraduate geriatric education in foreign countries].

In Japan, which has become a super-aged society, medical care for the elderly is more important than ever before. Geriatric education for medical students and young doctors is essential to ensure the best medical care possible for the elderly. In this paper, the Working Group for Education of the Japan Geriatrics Society collected and analyzed data and information on undergraduate education in the fields of geriatrics and gerontology at medical schools in various countries through the Internet, comparing the findings with those in Japan. Of the countries surveyed, 62% had undergraduate education in geriatrics and gerontology as mandatory subjects in medical school. Countries with advanced welfare programs, such as the United Kingdom, Germany, Austria, Denmark, Finland, Sweden, the Netherlands, Spain, Canada and New Zealand, performed substantial undergraduate education in geriatrics and gerontology. A lack of available staff and time for education was cited as a hurdle in many countries. The importance of education in geriatrics and gerontology is being emphasized in many countries, but few programs are satisfactory at present. The "struggle" to improve undergraduate education in geriatrics and gerontology therefore continues. We should endeavor to improve education in the fields of geriatrics and gerontology by working hand in hand with geriatricians and gerontologists around the world.

Association of self-reported moderate vegetable juice intake with small decline in kidney function in a five-year prospective study.

OBJECTIVES: Although consumption of vegetable and 100% fruit juices are an acceptable alternative for vegetable and fruit intake, information about their actual effects on kidney function is sparse. The aim of this study was to determine the association between the consumption of vegetable and fruit juices and changes in kidney function in a Japanese population over a 5-y period. METHODS: In this prospective study, we analyzed 2755 Japanese (742 men and 2013 women) individuals who participated in both the baseline and follow-up surveys in the Daiko study (a study within the Japan Multi-Institutional Collaborative Cohort study). Estimated glomerular filtration rate (eGFR) was calculated by age, sex, and serum creatinine level. For each beverage, we categorized all participants into four groups-rare (rarely consumed), low (≤2 cups/wk), moderate (3-4 cups/wk), or frequent (≥5 cups/wk) consumers of the beverage-based on a food frequency questionnaire. RESULTS: The mean baseline and follow-up eGFR (SD) were 82.4 (14.6) and 72.2 (12.6), respectively. In fully adjusted regression analyses, moderate consumption of vegetable juice was associated a lower decline in eGFR compared with the rare consumption group (ß = -1.30; P = 0.01). Moreover, stratified analyses revealed that this significant association remained in those who were young, female, non-obese, normotensive, smoked cigarettes, consumed alcohol, or exercised. However, no significant association was found in analyses for fruit juices. CONCLUSIONS: This 5-y prospective study suggested an association between self-reported moderate consumption of vegetable juice and changes (possibly smaller decline) in kidney function in a relatively healthy Japanese population.
