ABSTRACT

In 1952, the Japanese Society for Hygiene had once passed a resolution at its 22nd symposium on population control, recommending the suppression of population growth based on the idea of cultivating a healthier population in the area of eugenics. Over half a century has now passed since this recommendation; Japan is witnessing an aging of the population (it is estimated that over 65-year-olds made up 27.7% of the population in 2017) and a decline in the birth rate (total fertility rate 1.43 births per woman in 2017) at a rate that is unparalleled in the world; Japan is faced with a "super-aging" society with low birth rate. In 2017, the Society passed a resolution to encourage all scientists to engage in academic researches to address the issue of the declining birth rate that Japan is currently facing. In this commentary, the Society hereby declares that the entire text of the 1952 proposal is revoked and the ideas relating to eugenics is rejected. Since the Society has set up a working group on the issue in 2016, there have been three symposiums, and working group committee members began publishing a series of articles in the Society's Japanese language journal. This commentary primarily provides an overview of the findings from the published articles, which will form the scientific basis for the Society's declaration. The areas we covered here included the following: (1) improving the social and work environment to balance between the personal and professional life; (2) proactive education on reproductive health; (3) children's health begins with nutritional management in women of reproductive age; (4) workplace environment and occupational health; (5) workplace measures to counter the declining birth rate; (6) research into the effect of environmental chemicals on sexual maturity, reproductive function, and the children of next generation; and (7) comprehensive research into the relationship among contemporary society, parental stress, and healthy child-rearing. Based on the seven topics, we will set out a declaration to address Japan's aging society with low birth rate.

ABSTRACT

BACKGROUND@#In health examinations for local inhabitants in cadmium-polluted areas, only healthy people are investigated, suggesting that patients with severe cadmium nephropathy or itai-itai disease may be overlooked. Therefore, we performed hospital-based screening to detect patients with cadmium nephropathy in two core medical institutes in cadmium-polluted areas in Akita prefecture, Japan.@*METHODS@#Subjects for this screening were selected from patients aged 60 years or older with elevated serum creatinine levels and no definite renal diseases. We enrolled 35 subjects from a hospital in Odate city and 22 from a clinic in Kosaka town. Urinary ß-microglobulin and blood and urinary cadmium levels were measured.@*RESULTS@#The criteria for renal tubular dysfunction and the over-accumulation of cadmium were set as a urinary ß-microglobulin level higher than 10,000 μg/g cr. and a blood cadmium level higher than 6 μg/L or urinary cadmium level higher than 10 μg/g cr., respectively. Subjects who fulfilled both criteria were diagnosed with cadmium nephropathy. Six out of 57 patients (10.5% of all subjects) had cadmium nephropathy.@*CONCLUSIONS@#This hospital-based screening is a very effective strategy for detecting patients with cadmium nephropathy in cadmium-polluted areas, playing a complementary role in health examinations for local inhabitants.@*REGISTRATION NUMBER@#No. 6, date of registration: 6 June, 2010 (Akita Rosai Hospital), and No. 1117, date of registration: 26 December, 2013 (Akita University).

ABSTRACT

<p><b>OBJECTIVE</b>To examine maternal and fetal exposure levels to four carcinogenic metals, arsenic (As), cadmium (Cd), nickel (Ni), and beryllium (Be), and to investigate their environmental influences.</p><p><b>METHODS</b>Metal concentrations in maternal and umbilical cord blood were measured by inductively coupled plasma-mass spectrometry (ICP-MS). Environmental factors that might play a role in exposure were analyzed using Mann-Whitney nonparametric U-tests and multiple linear regression.</p><p><b>RESULTS</b>The concentrations of As, Cd, and Ni in umbilical cord blood (5.41, 0.87, and 139.54 μg/L) were significantly lower than those in maternal blood (6.91, 1.93, and 165.93 μg/L). There were significant positive correlations between the maternal and cord concentrations of each carcinogen. Our results showed that: (i) exposures to potentially harmful occupational factors during pregnancy were associated with high levels of maternal As, Cd, and Ni; (ii) living close to major transportation routes (<500 m) or exposure to second-hand smoke during pregnancy increased the maternal Cd levels and (iii) living close to industrial chimneys induced high maternal Ni levels. Multiple linear regression analysis showed that these environmental factors remained significant in models of the influences of these four carcinogens.</p><p><b>CONCLUSION</b>Both mothers and fetuses had been exposed to As, Cd, Ni, and Be. The increased levels of these carcinogens in pregnant women were associated with some detrimental environmental factors, such as occupational exposure, contact with second-hand smoke and living close to major transportation routes or industrial chimneys.</p>

ABSTRACT

Early clinical exposure has been implemented worldwide as an effective method of medical education. The duration of early clinical exposure is 1 year in some universities in Western countries. In Japan, however, early clinical exposure occurs most often through health and welfare services, and its duration varies. One-year early clinical exposure and reflection upon it were implemented for first-year students at Mie University School of Medicine in 2006 to motivate them and to teach them about professionalism. The effectiveness of this program was evaluated with a questionnaire, a daily log, and a portfolio.1) The questionnaire survey revealed that students considered the program extremely valuable. They had learned much about communication skills, the relationship between medicine and society, patients' families, and professionalism.2) An analysis of the daily logs clearly showed that students were unsure and hesitant at the start of the program. However, they gradually became accustomed to participating in this program and began to learn earnestly.3) Qualitative analysis of the portfolios revealed that students considered 10 items important in the practice of medicine, including communication skills, responsibility, the value of being a physician, professionalism, and the motivation to study medicine.4) In their final reports, the students described the expected behaviors of physicians they should seek to perform, by learning medical ethics or through professionalism.5) In conclusion, 1-year early clinical exposure is a more effective method than short-term or intermittent exposure for medical students because of its uniqueness and the maintenance of motivation.

ABSTRACT

The quality of medical education should be improved so that a physician's entire personality is nurtured. To this end, applying teaching methods from overseas educational institutions at Japanese medical schools would be beneficial. A discussion class taught at the University of Iowa is designed to increase the efficiency and consistency of interactive education. Numerous techniques for teaching discussion introduced at the University of Iowa might help improve the problembased learning methods now commonly used at Japanese medical schools. Moreover, the University of Iowa's method for teaching communication skills, which emphasizes interaction between instructors and students, can provide a model for medical students to acquire essential skills. Therefore, examining the comprehensive teaching system at the University of Iowa will help medical schools fulfill their expected social mission.
