Artificial organs and regenerative medicine are the subjects of very active research and development (R&D) in Japan and various artificial organs are widely used in patients. Results of the R&D are presented at the annual conference of the Japanese Society for Artificial Organs (JSAO). Progress in the fields of artificial organs and regenerative medicine are reviewed annually in the Japanese Journal of Artificial Organs. The official English-language journal of JSAO, Journal of Artificial Organs, also publishes many original articles by Japanese researchers. Although the annual conference and the publications of JSAO provide the world with update information on artificial organs and regenerative medicine in Japan, the information is not always understood appropriately in the rest of the world, mainly due to language problems. This article therefore introduces the current status of artificial organs and regenerative medicine in Japan. Artificial hearts and metabolic support systems are reviewed here and other interesting areas such as regenerative medicine can be found elsewhere.

Research on rare diseases cannot be performed without appropriate samples from patients with such diseases. Due to the limited number of such patients, securing biosamples of sufficient quality for extensive research is a challenge and represents an important barrier to the advancement of research on rare diseases. To tackle this problem, the Rare Disease Bank (RDB) was established in 2009 at the National Institute of Biomedical Innovation (NIBIO; currently, the National Institutes of Biomedical Innovation, Health and Nutrition in Japan). Since then, the RDB has focused on three objectives: (1) emphasizing the importance of collecting biosamples from patients with rare diseases, together with appropriate clinical information, from various medical facilities nationwide; (2) maintaining strict high-quality sample management standards; and (3) sharing biosamples with research scientists across Japan for the advancement of research on rare diseases. As of August 2017, the bank has collected 4147 biosamples from patients with rare diseases, including DNA, serum, plasma, and cell samples from various university hospitals and other medical institutions across the country, and provided various research institutions with 13,686 biosample aliquots from 2850 cases. In addition, the management committee has successfully established a bank system that provides high-quality biosamples together with the results of human leukocyte antigen analysis. It is anticipated that the RDB, through the collection and sharing of biosamples with the medical research community, will enhance the understanding, prevention, and treatment of rare diseases in Japan and the world at large.

SCRUM-Japan was launched as a nation-wide genome screening consortium for recruiting patients to 35 sponsor-/investigator- initiated registration trials in collaboration with 15 pharmaceutical companies and 240 hospitals. During the first period between February 2015 and March 2017, a total of 4,805 patients have been enrolled. Genomic profiling of each cancer were analyzed and newdrug applications of label expansion are in preparation based on the results of several registration studies including investigator-initiated trial of vandetanib for RET fusion gene positive non-small cell lung cancer. In addition, on-time clinical-genome data sharing with industries and academic institutions and prospective cohort registry for new drug evaluation as a historical control data have already initiated, which will facilitate new agent development in Japan. In the second period started from April 2017, new studies using cutting-edge liquid biopsy and immune-genome panel for precision medi- cine will start soon. These efforts are attempted towards a leading group for innovative clinical/translations researches in the world.

Osteo/chondrogenic differentiation capabilities are seen after in vivo implantation of mesenchymal stem cells (MSCs), which are currently used for the patients having bone/cartilage defects. Importantly, the differentiation capabilities are induced by culturing technology, resulting in in vitro bone/cartilage formation. Especially, the in vitro bone tissue is useful for bone tissue regeneration. For cartilage regeneration, culture expanded chondrocytes derived from patient's normal cartilage are also used for the patients having cartilage damages. Recently, the cultured chondrocytes embedded in atelocollagen gel are obtainable as tissue engineered products distributed by Japan Tissue Engineering Co. Ltd. The products are available in the well-regulated hospitals by qualified orthopedic surgeons. The criteria for these hospitals/surgeons have been established. This review paper focuses on current status of bone/cartilage tissue engineering towards clinical applications in Japan.

Background In this study, we examined the current status of psychosocial or psychological intervention for women during pregnancy and the postpartum period in Japan. Methods We estimated the number of women receiving perinatal psychosocial or psychological intervention in Japan. On December 2015, we requested 2,462 obstetrical facilities that are members of the Japan Association of Obstetricians and Gynecologists (JAOG) to provide information on women who received psychosocial or psychological intervention during pregnancy, the hospitalization period for childbirth and the puerperal 1 month in 2014. A total of 1,305 (53.0%) of the 2,462 obstetrical facilities responded with valid information on a total of 515,373 women, accounting for approximately 52% of all deliveries that occurred in Japan during the study period. Results The number of women who received psychosocial or psychological intervention during pregnancy, the hospitalization period for childbirth and the puerperal 1 month were 4,843 (0.94%), 4,791 (0.93%) and 3,015 (0.59%), respectively. In total, 8,743 women (1.70%) received psychosocial or psychological intervention in 2014. Conclusion Considering the response rate, the number of women requiring perinatal psychosocial or psychological intervention was estimated to be 16,000 per year in Japan. PMID:27222675

People spend more than two thirds of their daily time indoors. Hence, maintaining a healthy indoor environment is indispensable for the prevention of building related illness. In Japan, guidelines for indoor air quality have been established for 13 volatile/semi-volatile organic compounds (VOCs/SVOCs). These guidelines are now under revision by the Committee on Sick House Syndrome: Indoor Air Pollution. In order to gain information on the current indoor air pollutants and their levels, we carried out a nation-wide survey of VOCs and aldehydes in indoor residential air during 2012-2013. In this review, I concisely summarized the current indoor air quality of Japan.

The current status and problems confronted in delivering precision medicine in Japan and Europe.

PubMed

Bando, Hideaki

Precision medicine has been defined as "a predictive, preventive, personalized, and participatory health care service delivery model." Today, developments in next-generation sequencing and information technology have made precision medicine possible, with massive amounts of genetic, "omics," clinical, environmental, and lifestyle data now available. Unfortunately, differences in governmental support and health care regulations have resulted in heterogeneous progress among countries. In Japan, for example, precision cancer screening and treatments are increasingly being promoted, with collaboration among research, governmental, and pharmaceutical agencies taking place in the nationwide SCRUM-Japan cancer genome screening project. The missions of SCRUM-Japan are to deliver the most appropriate therapeutic agents to the most suitable patients, and to play key roles in the development of multiplex diagnostic products and new indications for targeted therapy. Starting in February 2015 and ending in March 2017, the aim is to enroll 4750 patients with cancer (2350 patients with lung cancer and 2400 patients with gastrointestinal tract cancer). Compared with other developed countries, investments in scientific innovation for biomedical and omics research are matched or even surpassed in Europe, but regulatory differences in each countries are a major hurdle to rapid implementation. Although market approval for pharmaceuticals is centralized through the European Medicines Agency, access to health care is heterogeneously regulated at national levels, which undermines the consistency, comparability, and quality of precision medicine for cancer patients in Europe. In this review, we focus on the current progress of precision medicine in Japan and Europe, and clarify the differences in progress and the hurdles faced moving forward.

2016-12-07

The participation of women in the Japanese labor force is characterized by its M-shaped curve, which reflects decreased employment rates during child-rearing years. Although, this M-shaped curve is now improving, the majority of women in employment are likely to fall into the category of non-regular workers. Based on a review of the previous Japanese studies of the health of non-regular workers, we found that non-regular female workers experienced greater psychological distress, poorer self-rated health, a higher smoking rate, and less access to preventive medicine than regular workers did. However, despite the large number of non-regular workers, there are limited researches regarding their health. In contrast, several studies in Japan concluded that regular workers also had worse health conditions due to the additional responsibility and longer work hours associated with the job, housekeeping, and child rearing. The health of non-regular workers might be threatened by the effects of precarious employment status, lower income, a lower safety net, outdated social norm regarding non-regular workers, and difficulty in achieving a work-life balance. A sector wide social approach to consider life course aspect is needed to protect the health and well-being of female workers' health; promotion of an occupational health program alone is insufficient.

The guidelines for the management of hypertension recommend the inclusion of diuretics, especially when three or more antihypertensive drugs are used. The present study investigated the current prescription status of antihypertensive drugs with a particular focus on the use of diuretics in a local district in Japan. Prescriptions, including antihypertensive drugs, were collected from a dispensing pharmacy of the Yahata Pharmacist Association, located in Kitakyushu City, in October 2014. Of the 10 585 prescriptions, calcium channel blockers (CCBs) were prescribed in 73.5%, followed by angiotensin II receptor blockers (ARB, 62.7%), diuretics (16.5%) and β-blockers (13.6%). The average number of drugs used was 1.80. The rates of prescription of diuretics for patients with one, two, three and four drugs were 0.6%, 13.1%, 55.2% and 82.6%, respectively. Diuretics were more frequently prescribed in elderly patients, and the prescription rate of doctors in hospitals was significantly higher than that of general practitioners (19.1% vs. 15.7%, P<0.01). In addition, 40% of patients with thiazide diuretics were prescribed combination tablets of hydrochlorothiazide with ARB, whereas trichlormethiazide (34.9%) and indapamide (19.8%) were used in other patients. Based on these findings, the use of diuretics remains limited, even among patients taking multiple antihypertensive drugs.

Gene-based vaccines as typified by plasmid DNA vaccines and recombinant viral-vectored vaccines are expected as promising solutions against infectious diseases for which no effective prophylactic vaccines exist such as HIV, dengue virus, Ebola virus and malaria, and for which more improved vaccines are needed such as tuberculosis and influenza virus. Although many preclinical and clinical trials have been conducted to date, no DNA vaccines or recombinant viral-vectored vaccines expressing heterologous antigens for human use have yet been licensed in the U.S., Europe or Japan. In this research, we describe the current regulatory context for gene-based prophylactic vaccines against infectious disease in the U.S., Europe, and Japan. We identify the important considerations, in particular, on the preclinical assessments that would allow these vaccines to proceed to clinical trials, and the differences on the regulatory pathway for the marketing authorization in each region.

The majority of studies on the role of psychological resources linking childhood socioeconomic status (SES) and adult health have been conducted in Western countries. Empirical evidence for mediation effects of psychological resources is currently lacking in Japan. The purpose of this study was to investigate the mediating effect of psychological resources (mastery and sense of coherence [SOC]) on the association between childhood SES and current health. Analyses were conducted on cross-sectional data (1,497 men and 1,764 women) from the Japanese Study of Stratification, Health, Income, and Neighborhood Study (J-SHINE) in Tokyo. Psychological resources (mastery and SOC), childhood SES (parents' education and perceived childhood SES), and current health of adults (psychological distress measured by K6 and self-rated health) were measured using a self-report questionnaire. Mastery and SOC significantly and independently mediated the association between childhood SES and current health in the total sample after adjusting for age, gender, and respondent education, regardless of type of SES or health outcome indicators. Similar mediation effects were observed for both men and women. A few gender differences were observed; specifically, SOC significantly mediated the association between parents' education and current health only among women, and it mediated the association between perceived childhood SES and current health only among men. Overall, the findings underscore the importance of the mediating role of psychological resources in the association between childhood SES and current health.

Over the past few decades, the longest extension in life expectancy in the world has been observed in Japan. However, the sophistication of medical care and the expansion of the aging society, leads to continuous increase in health-care costs. Medical expenses as a part of gross domestic product (GDP) in Japan are exceeding the current Organization for Economic Co-operation and Development (OECD) average, challenging the universally, equally provided low cost health care existing in the past. A universal health insurance system is becoming a common system currently in developed countries, currently a similar system is being introduced in the United States. Medical care in Japan is under a social insurance system, but the injection of public funds for medical costs becomes very expensive for the Japanese society. In spite of some urgently decided measures to cover the high cost of advanced medical treatment, declining birthrate and aging population and the tendency to reduce hospital and outpatients' visits numbers and shorten hospital stays, medical expenses of Japan continue to be increasing.

Menstrual problems can significantly impact daily and work life. In reaction to a shrinking population, the Japanese government is encouraging more women to participate in the labor force. Actual success in achieving this aim, however, is limited. Specifically, participation in the workforce by women during their reproductive years is impacted by their health, which involves not only work conditions, but also traditional family circumstances. Therefore, it is important to further assess and gather more information about the health status of women who work during their reproductive years in Japan. Specifically, women's health can be represented by menstruation status, which is a pivotal indicator. In this study, we assessed the association between short rest periods in work intervals and menstruation and other health status indicators among female workers in Japan. Study participants were recruited from the alumnae of a university, which provided a uniform educational level. All 9864 female alumnae were asked to join the survey and 1630 (17%) accepted. The final sample of study participants ( n  = 505) were aged 23-43 years, had maintained the same job status for at least 1 year, and were not shift workers, had no maternal status, and did not lack any related information. The participants were divided into two groups according to interval time, with 11 h between end of work and resumption of daily work as a benchmark. This interval time was based on EU regulations and the goal set by the government of Japan. Health outcomes included: menstrual cycle, dysmenorrhoea symptoms, anxiety regarding health, and satisfaction in terms of health. Multiple logistic regression analyses were conducted to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for health indexes in association with interval time by adjusting for confounding variables that included both psychosocial and biological factors. We compared the health status of women in the workforce with

The red panda (Ailurus fulgens) is an endangered semi-arboreal folivore with a specialized diet of bamboo leaves. Zoos worldwide maintain red pandas under a variety of housing environments and husbandry procedures that may affect the reproductive success and longevity of captive red pandas. The aims of the present study were to investigate how red pandas are kept in Japan and to obtain useful insights to increase their longevity by comparing the results from a questionnaire sent to Japanese zoos and those from a previous survey conducted in other countries. We received responses from 42 out of 52 zoos, holding a total of 219 individual red pandas, in Japan. The age-sex distribution indicated that red panda populations in Japan need close attention to be maintained sustainably. Of the husbandry aspects surveyed, the number of individuals in the same zoo, enclosure size, and the frequency of bamboo feeding factors indicated to affect reproductive success. Frequent monitoring of body weight, implementation of husbandry training, and bamboo feeding were also suggested as the reasons for the longevity of red pandas in Japan. Zoos were provided with sufficient physical features in on-exhibit enclosures, close monitoring for health status, and proper feeding, but other aspects of husbandry such as enclosure size and structures in off-exhibit spaces were insufficient and might compromise animal welfare. © 2018 Wiley Periodicals, Inc.

Since the International Commission on Radiological Protection recommended reducing the occupational equivalent dose limit for the lens of the eye in 2011, there have been extensive discussions in various countries. This paper reviews the current situation in radiation protection of the ocular lens and the discussions on the potential impact of the new lens dose limit in Japan. Topics include historical changes to the lens dose limit, the current situation with occupational lens exposures (e.g., in medical workers, nuclear workers, and Fukushima nuclear power plant workers) and measurements, and the current status of biological studies and epidemiological studies on radiation cataracts. Our focus is on the situation in Japan, but we believe such information sharing will be useful in many other countries.

Recent studies have reported an association between periodontal disease and mortality among dialysis patients. Therefore, preventive dental care should be considered very important for this population. In Japan, no systematic education has been undertaken regarding the importance of preventive dental care for hemodialysis patients--even though these individuals tend to have oral and dental problems. The aim of this study was to investigate the current state of collaborative relationships between hemodialysis facilities and dental services in Japan and also to identify strategies to encourage preventive dental visits among hemodialysis outpatients. A nationwide questionnaire on the collaborative relationship between dialysis facilities and dental facilities was sent by mail to all medical facilities in Japan offering outpatient hemodialysis treatment. Responses were obtained from 1414 of 4014 facilities (35.2%). Among the 1414 facilities, 272 (19.2%) had a dental service department. Approximately 100,000 dialysis outpatients were receiving treatment at these participating facilities, which amounts to one-third of all dialysis patients in Japan. Of those patients, 82.9% received hemodialysis at medical facilities without dental departments. Only 87 of 454 small clinics without in-house dental departments (19.2%) had collaborative registered dental clinics. Medical facilities with registered dental clinics demonstrated a significantly more proactive attitude to routine collaboration on dental matters than facilities lacking such clinics. Our nationwide survey revealed that most dialysis facilities in Japan have neither an in-house dental department nor a collaborative relationship with a registered dental clinic. Registration of dental clinics appears to promote collaboration with dental facilities on a routine basis, which would be beneficial for oral health management in hemodialysis patients.

To clarify the problems related to maternal deaths in Japan, including the diseases themselves, causes, treatments and the hospital or regional systems. Descriptive study. Maternal death registration system established by the Japan Association of Obstetricians and Gynecologists (JAOG). Women who died during pregnancy or within a year after delivery, from 2010 to 2014, throughout Japan (N=213). The preventability and problems in each maternal death. Maternal deaths were frequently caused by obstetric haemorrhage (23%), brain disease (16%), amniotic fluid embolism (12%), cardiovascular disease (8%) and pulmonary disease (8%). The Committee considered that it was impossible to prevent death in 51% of the cases, whereas they considered prevention in 26%, 15% and 7% of the cases to be slightly, moderately and highly possible, respectively. It was difficult to prevent maternal deaths due to amniotic fluid embolism and brain disease. In contrast, half of the deaths due to obstetric haemorrhage were considered preventable, because the peak duration between the initial symptoms and initial cardiopulmonary arrest was 1-3 h. A range of measures, including individual education and the construction of good relationships among regional hospitals, should be established in the near future, to improve primary care for patients with maternal haemorrhage and to save the lives of mothers in Japan.

Endoscopic submucosal dissection in the West: Current status and future directions.

PubMed

Ma, Michael X; Bourke, Michael J

2018-05-01

Endoscopic submucosal dissection (ESD) was first conceptually described almost 30 years ago in Japan and is now widely practiced throughout East Asia. ESD expands the boundaries of endoscopic resection (ER) by allowing en bloc resection of large early neoplastic lesions within the gastrointestinal tract (GIT). This offers advantages over other ER techniques by facilitating definitive histological staging and curative treatment of early cancer in selected cases. Indeed, the experience of ESD in Eastern countries is significant, and excellent outcomes from high-volume centers are reported. The potential benefits of ESD are recognized by Western endoscopists, but its adoption has been limited. A number of factors contribute to this, including epidemiological differences in GIT neoplasia between Western and Eastern populations and limitations in training opportunities. In this review, we discuss the role of ESD, its current status and the future in Western endoscopic practice. © 2017 Japan Gastroenterological Endoscopy Society.

Medical oncology in Japan has a relatively short history, with specialist certification starting in 2006, resulting in 867 certified medical oncologists as of 2014. Although the national government has appointed 397 Designated Cancer Care Hospitals, little is known about the actual situations of medical oncology services at these institutions. Questionnaires regarding the presence of a medical oncology department, the number of physicians in the department, the presence of certified medical oncologists and the degree of the medical oncologists' responsibilities for drug therapies in adults with solid cancers were sent to all 397 institutions between 21 January and 1 May 2013. The response rate was 68.0%. Among the responses, 39.4% of the institutions had medical oncology departments with a median of three physicians. Most of the medical oncology departments were primarily responsible, as evaluated according to patient number, for the treatment of limited disease categories. The medical oncologists were significantly more responsible for molecular-targeted therapy than for chemotherapy in head and neck cancer or for cytokine therapy in renal cell carcinoma. The wide variety of adverse events associated with molecular-targeted therapy might have enhanced the roles of medical oncologists. As the proportion of hospitals with a medical oncology department increased according to the number of certified medical oncologists working at the institution, cultivating medical oncologists seems to be an urgent task for advancing medical oncology in Japan. The present study provides fundamental data for the future development of medical oncology in Japan. The present study is to uncover the current situation of medical oncology in Japan. © The Author 2014. Published by Oxford University Press. All rights reserved.

With the progress of medical care in recent years, the prognosis of intractable diseases of childhood onset has markedly improved. Young adults with special health care needs require continuous medical support throughout their lifetimes. To provide them with optimal health care services, a smooth transition from the pediatric medical system to the adult one is essential. However, in Japan many adult health providers are not sufficiently prepared to care for these patients, due both to limited opportunities to gain up-to-date medical knowledge on transitional health care and a lack of familiarity with the medical treatment of childhood-onset chronic diseases. In this review, we discuss current issues in transitional health care in Japan from an internist's viewpoint.

The current status of the TAMA and CLIO detectors in Japan is reported in this paper. These two interferometric gravitational wave detectors are being developed for the large cryogenic gravitational wave telescope (LCGT) which is a future plan for detecting gravitational wave signals at least once per year. TAMA300 is being upgraded to improve the sensitivity in a low-frequency region after the last observational experiment in 2004. To reduce the seismic noises, we are installing a new seismic isolation system, called the TAMA seismic attenuation system, for the four test masses. We confirmed stable mass locks of a cavity and improvements of length and angular fluctuations by using two SASs. We are currently optimizing the performance of the third and fourth SASs. We continue TAMA300 operation and R&D studies for the LCGT. The next data taking is planned for the summer of 2007. CLIO is a 100 m baseline length prototype detector for LCGT to investigate interferometer performance in cryogenic condition. The key features of CLIO are that it locates the Kamioka underground site for a low-seismic noise level, and adopts cryogenic Sapphire mirrors for low-thermal noise level. The first operation of the cryogenic interferometer was successfully demonstrated in February 2006. Current sensitivity at room temperature is close to the target sensitivity within a factor of 4. Several observational experiments at room temperature have been done. Once the displacement noise reaches the thermal noise level of room temperature, its improvement by cooling test mass mirrors should be demonstrated.

Neuropsychology in Japan: history, current challenges, and future prospects.

The purpose of this special issue was to describe the cross-cultural differences in neuropsychology throughout the world. The current state of neuropsychology in Japan is discussed in this manuscript. Information on six topics, including (1) the history of Japanese neuropsychology, (2) licensure system, (3) job opportunities, (4) neuropsychological clinical services, (5) neuropsychological tests, and (6) neuropsychological research, was gathered via literature searches, official organization websites, and personal communication with clinical psychologists and other professionals in Japan. Neuropsychology reached Japan from the west in the late 1800s, a period of rapid political and social modernization. Professional associations were founded in the 1960s and 1970s and continued to grow. The need for neuropsychological assessment in Japan is growing; however, credential requirements for neuropsychologists have not yet been established. To practice clinical psychology in Japan, one must obtain a Master's degree and pass a licensure examination that is administered by a private professional foundation. Clinical psychologists often conduct neuropsychological tests; however, they have little training in neuropsychological assessment. While many western neuropsychological tests have been translated into Japanese and are used in clinical settings, the majority of translated tests have not been standardized and their psychometric properties remain poorly understood. Standardization and development of normative data in Japan is warranted. Given that needs for neuropsychological services are increasing, it is essential for clinical psychologists in Japan to improve their skills in neuropsychological evaluations. Japanese graduate schools must work to establish neuropsychology programs to educate and train clinical neuropsychologists.

Training systems for occupational physicians (OPs) have existed since the Industrial Safety and Health Act was enacted in 1972. However, it is necessary to enhance them because of changes in the business environment of Japanese corporations and working patterns have brought about new needs of occupational health (OH) activities. In this paper, OPs were classified into three categories; doctors who spend a part of working time on OH activities, i.e. "non-specialist OPs", doctors who engage in OH activities full-time, i.e. "specialists OPs", and doctors who manage corporate-wide occupational health programs or lead programs at OH service institutes, i.e. "lead OPs", and the status and the issues were reviewed. The major concern identified for each of the three categories in training were found to be quality management for non-specialist OPs, short supply for specialists OPs, and development of competencies such as leadership and management skills for lead OPs, respectively. Current efforts and ideas to improve the training systems were discussed.

There is a low autopsy rate and wide distribution of computed tomography (CT) and magnetic resonance imaging (MRI) scanners in Japan. Therefore, many Japanese hospitals, including 36% of the hospitals with in-patient facilities and 89% of large hospitals with ER facilities conduct postmortem imaging (PMI), use clinical scanners to screen for causes in unusual deaths as an alternative to an autopsy or to determine whether an autopsy is needed. The Japanese PMI examination procedure is generally referred to as "autopsy imaging" (Ai) and the term "Ai" is now commonly used by the Japanese government. Currently, 26 of 47 Japanese prefectures have at least one Ai Center with scanners that are dedicated for PMI. Here, we briefly review the history of Japanese PMI (Ai) from 1985 to the present.

High proportion of Japanese uses condoms; lower proportion uses oral contraceptive pills (OCPs). We examined the longitudinal patterns for contraceptive usage in Japan and evaluated differences before and after OCP government approval. We accessed nationally representative survey data for women aged 16-49years from 1950 to 2014. Usage of condoms and OCP was 83.4% and 3.0%, respectively in 2014. OCP use before (1.21%) and after (1.97%) government approval did not differ significantly (p=.58). The prevalence of OCP usage remains low in Japan. A wide gap in use between Japan and other developed countries exists. Through a wide gap in OCP use between Japan and other countries, we revealed how choices of contraceptive methods and their benefits could be openly available for women of reproductive age, and how health care professionals disseminate appropriate knowledge about contraception for women in need.

The rapid growth of the elderly population and the progress in surgical techniques in Japan have led to increased numbers of patients who undergo surgery. Anesthetics are essential for surgery. A survey conducted by the Japanese Society of Anesthesiologists showed that, during the past 10 years, the proportion of females among all the members has increased from 27 to 35 %, and the proportion of female councilors has risen from 3.9 to 6.7 %. However, the conditions of full-time employment remain inadequate for female physicians. Therefore, many female physicians in their 30s or older do not work as anesthesiologists. To support female anesthesiologists and their vital roles in surgical diagnosis and treatment, return-to-work assistance programs have been developed. It is also necessary to improve the working conditions for female anesthesiologists to allow them to continue their work, and to provide education for young female physicians to enhance their professional pride.

Data are limited on the sex-specific prevalence of diseases and their risk factors in middle-aged and older workers in Japan. In this cross-sectional study, we investigated the age- and sex-specific prevalence of hypertension, diabetes, dyslipidemia, metabolic syndrome (defined using joint statement criteria), obesity, underweight, abdominal obesity, and smoking among approximately 70,000 to 90,000 Japanese workers (predominantly men) aged 20–69 years in 2014. We also investigated the prevalence of low cardiorespiratory fitness in 2012 and no leisure-time exercise in 2014. In both sexes, the prevalence of lifestyle-related risk factors, including hypertension, diabetes, dyslipidemia, metabolic syndrome, obesity, and abdominal obesity, was increased with aging. In contrast, the prevalence of underweight was decreased with aging. Smoking prevalence exceeded 30% in men regardless of age, whereas the prevalence was around 10% in women of all age groups. Prevalence of no leisure-time exercise exceeded 50% among middle-aged and older workers in both sexes. Among workers aged 50–64 years, less than half of men had low fitness, whereas more than half of women had low fitness. Given the high prevalence of lifestyle-related risk factors among middle-aged and older workers, effective strategies to prevent cardiovascular disease in this age group are needed in Japan.

2011-07-01

The radiation dose to workers at nuclear power stations (NPSs) in Japan was drastically reduced between the late-1970s and the early-1990s by continuous dose-reduction programmes. The total collective dose of radiation workers in FY 2008 was 84.04 person Sv, while the average collective dose was 1.5 person Sv per reactor. The average annual individual dose was 1.1 mSv and the maximum annual individual dose was 19.5 mSv. These values are sufficiently lower than the regulatory dose limits. Radioactive effluent released from NPSs is already so trivial that additional protective measures will not be necessary. Experience in radiation protection at NPSs has been accumulated over 40 y and will be very useful in establishing a rational radiation control system in the future.

Published reports have shown the prevalence and incidence of gastroesophageal reflux disease (GERD) is increasing in Japan. The objective of this study is to examine change in GERD incidence, and to understand current patient demographics, medical costs, treatment status, and the suitability of current treatment based on analysis of an insurance claims database. An insurance claims database with data on ∼1.9 million company employees from January 2005 to May 2015 was used. Prevalence, demographics, and medical costs were analyzed by cross-sectional analysis, and incidence and treatment status were analyzed by longitudinal analysis among newly-diagnosed GERD patients. GERD prevalence in 2014 was 3.3% among 20-59 year-olds, accounting for 40,134 people in the database, and GERD incidence increased from 0.63% in 2009 to 0.98% in 2014. In 2014, mean medical cost per patient per month for GERD patients aged 20-59 was JPY 31,900 (USD 266 as of January 2016), which was ∼2.4-times the mean national healthcare cost. The most frequently prescribed drugs for newly-diagnosed GERD patients were proton pump inhibitors (PPIs). Although PPIs were prescribed more often in patients with more doctor visit months, over 20% of patients that made frequent doctor visits (19 or more visits during a 24 calendar months period) were prescribed PPIs during only 1 calendar month or not at all. The database included only reimbursable claims data and, therefore, did not cover over-the-counter drugs. The database also consisted of employee-based claims data, so included little data on people aged 60 years and older. Given the increasing incidence of GERD in Japan there is a need for up-to-date information on GERD incidence. This study suggests that some GERD patients may not be receiving appropriate treatment according to Japanese guidelines, which is needed to improve symptom control.

The Japan Cardiovascular Surgery Database (JCVSD) was created in 2000 with the support of the Society of Thoracic Surgeons (STS). The STS database content was translated to Japanese using the same disease criteria and in 2001, data entry for adult cardiac surgeries was initiated online using the University Hospital Medical Information Network (UMIN). In 2008, data entry for congenital heart surgeries was initiated in the congenital section of JCVSD and preoperative expected mortality (JapanSCORE) in adult cardiovascular surgeries was first calculated using the risk model of JCVSD. The Japan Surgical Board system merged with JCVSD in 2011, and all cardiovascular surgical data were registered in the JCVSD from 2012 onward. The reports resulting from the data analyses of the JCVSD will encourage further improvements in the quality of cardiovascular surgeries, patient safety, and medical care in Japan.

Compared with developed foreign countries, anti-smoking measures in Japan is lagging behind. As a country that has signed the Framework Convention on Tobacco Control (FCTC), it should be run the appropriate tobacco control. For example, in many stores of the service industry that smoking is allowed, employees are working while being exposed to second-hand smoke. Even in workplace air polluted environment, employees will not be able to leave there. Such a harsh environment to ignore health and safety, it must be eliminated as soon as possible. In order to protect the health of workers, the workplace should be smoke free.

Epstein-Barr virus (EBV) infection is usually asymptomatic and persists lifelong. Although EBV-infected B cells have the potential for unlimited proliferation, they are effectively removed by the virus-specific cytotoxic T cells, and EBV-associated lymphoproliferative disease develops only in immunocompromised hosts. Rarely, however, individuals without apparent immunodeficiency develop chronic EBV infection with persistent infectious mononucleosis-like symptoms. These patients have high EBV-DNA load in the peripheral blood and systemic clonal expansion of EBV-infected T cells or natural killer (NK) cells. Their prognosis is poor with life-threatening complications including hemophagocytic lymphohistiocytosis, organ failure, and malignant lymphomas. The term "chronic active EBV infection" (CAEBV) is now generally used for this disease. The geographical distribution of CAEBV is markedly uneven and most cases have been reported from Japan and other East Asian countries. Here we summarize the current understanding of CAEBV and describe the recent progress of CAEBV research in Japan. © 2014 Japan Pediatric Society.

In recent years, many analogs of narcotics have been widely distributed as easily available psychotropic substances and have become a serious problem in Japan. To counter the spread of these non-controlled substances, the Pharmaceutical Affairs Law in Japan was amended in 2006 to establish a new category; Designated Substances in order to more strictly control these substances. In April 2007, 31 compounds and 1 plant were first controlled as Designated Substances. Before 2007, the major compounds distributed in the Japanese illegal drug market were tryptamines, phenethylamines and piperazines. Alkyl nitrites, such as isobutyl nitrite and isopentyl nitrite, were also widely distributed. After they were listed as Narcotics or Designated Substances in 2007, these compounds, especially the tryptamines, quickly disappeared from the market. In their place, cathinone derivatives have been widely distributed, as well as different phenethylamines and piperazines. Additionally, in recent years, new herbal products containing synthetic cannabinoids have appeared globally. As at July 2012, 78 substances (including 1 plant; Salvia divinorum) were listed in the category of Designated Substances. They were 13 tryptamines, 17 phenethylamines, 11 cathinones, 4 piperazines, 23 synthetic cannabinoids, 6 alkyl nitrites, 3 other compounds and 1 plant. In this review, we show our survey of the spread of new designer drugs in Japan, focusing especially on synthetic cannabinoids and cathinone derivatives. Also, the prevalence and legal status of these substances in other countries will be presented.

To standardize educational programs and clinical training for medical physics students, the Japanese Board for Medical Physicist Qualification (JBMP) began to accredit master's, doctorate, and residency programs for medical physicists in 2012. At present, 16 universities accredited by the JBMP offer 22 courses. In this study, we aimed to survey the current status of educational programs and career paths of students after completion of the medical physicist program in Japan. A questionnaire was sent in August 2014 to 32 universities offering medical physicist programs. The questionnaire was created and organized by the educational course certification committee of the JBMP and comprised two sections: the first collected information about the university attended, and the second collected information about characteristics and career paths of students after completion of medical physicist programs from 2008 to 2014. Thirty universities (16 accredited and 14 non-accredited) completed the survey (response rate 94 %). A total of 209, 40, and 3 students graduated from the master's, doctorate, and residency programs, respectively. Undergraduates entered the medical physicist program constantly, indicating an interest in medical physics among undergraduates. A large percentage of the students held a bachelor's degree in radiological technology (master's program 94 %; doctorate program 70 %); graduates obtained a national radiological technologist license. Regarding career paths, although the number of the graduates who work as medical physicist remains low, 7 % with a master's degree and 50 % with a doctorate degree worked as medical physicists. Our results could be helpful for improving the medical physicist program in Japan.

The purpose of this study was to investigate the impact of income inequality and parental socioeconomic status on several birth outcomes in Japan. Data were collected on birth outcomes and parental socioeconomic status by questionnaire from Japanese parents nationwide (n = 41,499) and then linked to Gini coefficients at the prefectural level in 2001. In multilevel analysis, z scores of birth weight for gestational age decreased by 0.018 (95% confidence interval (CI): -0.029, -0.006) per 1-standard-deviation (0.018-unit) increase in the Gini coefficient, while gestational age at delivery was not associated with the Gini coefficient. For dichotomous outcomes, mothers living in prefectures with middle and high Gini coefficients were 1.24 (95% CI: 1.05, 1.47) and 1.23 (95% CI: 1.02, 1.48) times more likely, respectively, to deliver a small-for-gestational-age infant than mothers living in more egalitarian prefectures (low Gini coefficients), although preterm births were not significantly associated with income distribution. Parental educational level, but not household income, was significantly associated with the z score of birth weight for gestational age and small-for-gestational-age status. Higher income inequality at the prefectural level and parental educational level, rather than household income, were associated with intrauterine growth but not with shorter gestational age at delivery.

In Japan, it is illegal to sell pharmaceuticals on Internet auction sites, although a considerable number of pharmaceuticals are listed on such sites. We investigated the current situation regarding the illegal trade in pharmaceuticals on Japanese Internet auction sites and the responses of site administrators to such transactions. We searched for pharmaceuticals and "gray" items that were suspected of being pharmaceuticals on Yahoo-oku! (Yahoo! Auctions, Japan) over a 37-day period and then submitted violation reports indicating that selling pharmaceuticals is illegal or that the description of an item was insufficient. The reports were directed to the site administrators and forwarded to the sellers. One hundred and six pharmaceutical products and 34 gray items were identified during the study period. After the submission of the violation reports, only 28 of the pharmaceutical products and one of the gray items were deleted by the administrator, while 18 of the pharmaceutical products and 7 of the gray items were withdrawn by their sellers. However, 41 pharmaceuticals and 20 gray items were sold. Most of the gray items were listed using characteristic terms or abbreviations without photographic images. More than 70% of the identified pharmaceuticals had a contraindication(s) other than hypersensitivity. In conclusion, the illegal trade in pharmaceuticals on Internet auction sites remains a serious problem in Japan, and the responses of site administrators to such transactions are inadequate. The government and pharmaceutical industry may have to take measures such as providing public and administrative guidance to stop the illegal trade in pharmaceuticals on the Internet.

Taenia solium is a zoonotic cestode that causes taeniasis and cysticercosis in humans. The parasite is traditionally found in developing countries where undercooked pork is consumed under poor sanitary conditions and/or as part of traditional food cultures. However, the recent increase in international tourism and immigration is spreading the disease into non-endemic developed countries such as the United States. Although there has been concern that the number of cysticercosis cases is increasing in Japan, the current situation is not clear. This is largely because taeniasis and cysticercosis are not notifiable conditions in Japan and because there have been no comprehensive reviews of T. solium infections in Japan conducted in the last 15 years. Herein, we provide an overview of the status of T. solium infection in Japan over the past 35 years and point out the potential risks to Japanese society.

It is important to have a venous line in cardiopulmonary arrest (CPA) patients as an emergency treatment measure in prehospital settings, but establishment of a peripheral venous line is difficult in such patients. This study aimed to investigate the current status of intravenous infusion (IVI) in CPA patients by Emergency Life-Saving Technicians (ELSTs) in Japan. We also considered alternative measures in case IVI was difficult or impossible. We investigated a nationwide database between 1 January 2005 and 31 December 2008. From a total of 431,968 CPA cases, we calculated the IVI success rate and related parameters.The Bone Injection Gun (BIG) and simulator legs (adult, pediatric, and infant) were used by 100 ELSTs selected for the study to measure the time required and the success rate for intraosseous infusion (IOI). The number of CPA patients, IVI, adrenaline administration, and the IVI success rate in adult CPA patients increased every year. However, the IVI success rate in pediatric CPA patients did not increase. Although adrenaline administration elevated the ROSC rate, there was no improvement in the 1-month survival rate. The time required for IOI with BIG was not different among the leg models. The success rates of IOI with BIG were 93%, 94%, and 84% (p < 0.05 vs. adult and pediatric) in adult, pediatric, and infant models, respectively. The rate of success of IVI in adult CPA patients has been increased yearly in Japan. However, as establishing a peripheral venous line in pediatric patients (1-7 years old) by ELSTs is extremely difficult in prehospital settings, there was no increase in the IVI success rate in such patients. As the study findings indicated IOI with BIG was easy and rapid, it may be necessary to consider IOI with BIG as an alternative option in case IVI is difficult or impossible in adult and pediatric patients.

Current Challenges and Future Opportunities for Child and Adolescent Psychiatry in Japan

2017-01-01

Japan has been facing a serious shortfall of child and adolescent psychiatric workforce relative to increasing service needs. Likely because of a combination of limited workforce supply and limited trust or perception of effectiveness, mental health services are under-utilized by the educational and child welfare systems. Child and adolescent psychiatry (CAP) has not been a formally established specialty in Japan. The lack of basic structure in the specialty most likely contributes to a lack of training facilities, limited exposure to and interest in the specialty, and hence an inadequate workforce. To date, there exists no standardized training program for CAP in Japan and each training hospital determines its own teaching curriculum and training content. Clinical experience in CAP varies greatly among hospitals. To solve current problems in child and adolescent psychiatry in Japan, we advocate for the development and establishment of a more standardized child and adolescent psychiatry training system that is akin to what exists in the US and that teaches and evaluates according to specific competencies. Through standardizing care and education and ultimately improving workforce, the quality of mental health services can be raised. The tragic and costly consequences of unidentified and untreated mental illness in youth can be avoided by taking timely evidence based actions in partnership with others. PMID:29042875

This study examined how maternal work-related factors, including the availability of paid maternal leave, affect childhood vaccination status. Relatively little is known about the association between the employment status of mothers and the vaccination status of their children. We examined data from the Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE), an ongoing epidemiologic household panel study in Japan. We used surveys taken in 2010-2011 in this study. We found that mothers who returned to work after giving birth were much less likely to follow recommended vaccine schedules for their children compared with mothers who stayed at home and those who had left the workforce by the time of childbirth. However, taking parental leave significantly reduced the risk of not being up-to-date with the vaccination schedule at 36 months of age. We also found that children whose mother was younger and less educated, and those from an economically deprived family were at a high risk of not being up-to-date with the vaccination status at 36 months of age. Because vaccination is free and widely available in Japan, our findings indicate that provision of free vaccinations is not sufficient to achieve high vaccination rates.

[Current status of autism studies].

PubMed

Kurita, H

2001-01-01

The current status of autism studies was reviewed based on English articles published during the 1990s. Although the concepts of autism and pervasive developmental disorders (PDD) are established, diagnostic criteria of PDDNOS or atypical autism, which is frequently difficult to differentiate from autism, need to be established. The prevalence of autism has been estimated as about 0.05% in the U.S and many European countries, while it was reported to be 0.1% or higher in Japan and some European countries, though the reasons for this difference are unclear. High-functioning (IQ > or = 70) autism may not be as rare a condition as previously thought and both its difference from and similarity to Asperger's syndrome, the highest functioning PDD subtype, need clarification. About 20 to 40% of children with autism lose meaningful words by the age of 2 years and display autistic symptoms thereafter. Such autism, called the setback type in Japan, has been demonstrated to have a poorer adolescent/adult outcome compared to autism without setback and its relationship with childhood disintegrative disorder, which displays a clearer regression after normal development for at least the first 2 years of life, needs to be addressed. The etiology of autism is now considered mostly genetic for reasons, such as the significantly higher concordance rate of autism in identical twin pairs (60-80%) than in fraternal twin pairs (0-10%) and an 3-5% incidence of autism among sibs of an autism proband, 30 to 100 times higher than that in the general population. The involvement of several genes is implicated to create susceptibility for autism, yet the responsible genes have not been identified. Although there is no medication to cure autism, some psychotropic drugs, such as antipsychotics and SSRIs, seem effective for behavior problems in autism patients. Psychosocial treatments are the main therapeutic approach to autism, though they are yet to be well systematized. It is important to

An investigation on the health status of 79 male preparatory school students lodging at a dormitory in Japan was carried out by questionnaire on lifestyles, subjective symptoms and mental status, as compared with two control groups: 73 medical students and 36 new employees. About 83 % of them slept less than 6 hours and 70 % of them did not exercise. Many students are troubled with back pain or lumbago(47%), sensation of incomplete bladder emptying(l6%), loss of visual acuity(55%) and eye fatigue(65%). Self-rating depression scale score of preparatory school students was not significantly higher than those of the control groups. The lifestyles of preparatory school students found to be very restricted and strained. However, no significant differences on mental adverse health effects was found among three groups.

We analyzed the mortality and morbidity of congenital heart surgery in Japan using the Japan Cardiovascular Surgery Database (JCVSD). Data regarding congenital heart surgery performed between January 2013 and December 2014 were obtained from JCVSD. The 20 most frequent procedures were selected and the mortality rates and major morbidities were analyzed. The mortality rates of atrial septal defect repair and ventricular septal defect repair were less than 1%, and the mortality rates of tetralogy of Fallot repair, complete atrioventricular septal defect repair, bidirectional Glenn, and total cavopulmonary connection were less than 2%. The mortality rates of the Norwood procedure and total anomalous pulmonary venous connection repair were more than 10%. The rates of unplanned reoperation, pacemaker implantation, chylothorax, deep sternal infection, phrenic nerve injury, and neurological deficit were shown for each procedure. Using JCVSD, the national data for congenital heart surgery, including postoperative complications, were analyzed. Further improvements of the database and feedback for clinical practice are required.

[Purpose] This study aimed to elucidate the actual state of powered wheelchair (PWC) prescription for preschool children with disabilities in Japan, and also to determine the approximate number of preschool children with disabilities who would potentially benefit from PWC use. [Subjects and Methods] A total of 318 facilities providing rehabilitation for disabled children in Japan were enrolled in the study. A questionnaire about PWC use for preschoolers was mailed to the facilities. Each study items were analyzed employing the Fisher's exact test. [Results] Of the 318 facilities, consent to participate in this study was obtained from 108 (return rate: 34.0%). After PWC provision, many facilities reported improvement in quality of life indices for preschool children with disabilities. It was revealed that there were 6 preschool children from 2 to 6 years of age with disabilities who might acquire a means of independent locomotion through PWC provision and thereby experience improved quality of life. [Conclusion] There was no negative comment from the facilities studied about the prescription and provision of PWC for preschool children with disabilities. PMID:28289577

To determine the status of biosafety in clinical laboratories in Japan, we conducted a survey using questionnaires on the biosafety of laboratory personnel in 2004. We obtained data from 431 hospitals (response: 59.5%). Respondents were 301 institutions (70%) having biological safety cabinets (BSCs). BSCs were held in 78% of microbiological laboratories, 7.9% of genetic laboratories, 2.7% of histopathological laboratories, and 1% or less at other laboratories. A clean bench in examination rooms for acid-fast bacilli was applied at 20 hospitals. We found 28 cases of possible laboratory-associated tuberculosis infection, 25 of which were associated with lack of BSC. Other risk factors were immature skills and insufficiently skilled eguipment operation. The frequency of rupture accidents during specimen centrifugation was 67% in dealing with blood and 9.7% in collecting acid-fast bacilli. Half or more accidents were related to inadequate sample tube materials. Technologists were shown to be working on blood collection in many hospitals (75%), and 1,534 events of self-inflicted needle puncture developed in the last 5 years. These results suggest that biosafety systems are woefully lacking or inadequate in clinical laboratories in Japan and must be established at the earliest possible opportunity.

Taeniasis and cysticercosis due to Taenia solium in Japan

PubMed Central

2012-01-01

Taenia solium is a zoonotic cestode that causes taeniasis and cysticercosis in humans. The parasite is traditionally found in developing countries where undercooked pork is consumed under poor sanitary conditions and/or as part of traditional food cultures. However, the recent increase in international tourism and immigration is spreading the disease into non-endemic developed countries such as the United States. Although there has been concern that the number of cysticercosis cases is increasing in Japan, the current situation is not clear. This is largely because taeniasis and cysticercosis are not notifiable conditions in Japan and because there have been no comprehensive reviews of T. solium infections in Japan conducted in the last 15 years. Herein, we provide an overview of the status of T. solium infection in Japan over the past 35 years and point out the potential risks to Japanese society. PMID:22248435

In a global environment, education for healthcare professionals should include cultivating human resources who have the necessary skills to work in an international arena. This article will review the current status of English education for dental healthcare professionals in Japan. After conducting a literature search using the keywords: English education, Japan, and dental, only a few studies were found that investigated and proposed suggestions for dental professional English education. Even so, these were still in the early stages with outcomes yet to be fully evaluated. Even though English is thought indispensable for global professionals, and that increasing chances for communication skills is necessary, little attention has been addressed to English education for dental professionals or the implementation of such education in the Japanese undergraduate dental curricula. With the current reality of field expansion in dentistry, the need for not only improved English communication skills for Japanese dentists, but also the acquisition of essential expertise, psychomotor, teambuilding, critical thinking, and creative thinking skills in English as well as Japanese, is a definite probability. In order to reach this level of knowledge, further efforts and research would be necessary for the advancement and development of dental professional English education in Japan.

In 2005, the elderly generation comprised 20% of the Japanese population. This percentage will grow to approximately 30% in 2030, meaning that nearly one in three people in Japan will be 65 years of age or older. Japan is the first nation in the world to face this situation. This article uses the context of Japanese society to give an overview of the elderly and people with disabilities; the International Classification of Functioning, Disability, and Health model; rehabilitation engineering-related policy; and education. In addition, we examine how governmental programs and Japanese law regarding technical aids may evolve by 2030. Partner robots, intelligent powered wheelchairs, nursing robots, and other technologies are introduced as examples of rehabilitation engineering and assistive technology. We also discuss the volunteer activities of the Rehabilitation Engineering Society of Japan (RESJA) in response to the Asian tsunami disaster and the achievements of a group of students from a Japanese senior high school of industry.

Current Status of the Nitrogen Oxygen Recharge System

This paper presents an overview of the Nitrogen Oxygen Recharge System (NORS) to date and the current development status of the system. NORS is an element of the International Space Station (ISS) Environmental Control and Life Support Systems (ECLSS) used to resupply the ISS with Nitrogen and Oxygen following the impending retirement of the Space Shuttle. The paper will discuss why NASA is developing NORS, including a summary of other concepts considered, and other related concepts currently being developed by NASA. The current system architecture will be described, along with a summary of the current design of the NORS. The overall programmatic schedule of the NORS in the context of the upcoming shuttle retirement and future launch vehicle development will also be presented. Finally, the paper will examine the significant technical challenges encountered during the requirements and preliminary design phase of NORS development. A key challenge to the development of NORS is the international shipment - and associated regulations - of pressurized Oxygen, which is necessary due to the use of launch vehicles based in Japan and French Guiana to send NORS gasses to the ISS. The storage and use of relatively large quantities of high pressure (41,000 kPa) Oxygen and Nitrogen within the ISS, which is unprecedented both on the ISS and other space vehicles, has had a significant impact on the design and architecture of the system. The high pressure of the system also poses unique thermal considerations, which has led to the development of a heater system for thermal conditioning of high pressure gas to avoid thermal impacts on downstream hardware. The on-orbit envelope allocated to the NORS has changed (gotten smaller) and has impacted both the design and architecture of the system. Finally, the balance of safety considerations associated with these high pressure gasses, particularly high pressure Oxygen, with the functionality of the system has profoundly impacted the form

Current status of Kampo medicine curricula in all Japanese medical schools

2012-01-01

Background There have been a few but not precise surveys of the current status of traditional Japanese Kampo education at medical schools in Japan. Our aim was to identify problems and suggest solutions for a standardized Kampo educational model for all medical schools throughout Japan. Methods We surveyed all 80 medical schools in Japan regarding eight items related to teaching or studying Kampo medicine: (1) the number of class meetings, target school year(s), and type of classes; (2) presence or absence of full-time instructors; (3) curricula contents; (4) textbooks in use; (5) desire for standardized textbooks; (6) faculty development programmes; (7) course contents; and (8) problems to be solved to promote Kampo education. We conducted descriptive analyses without statistics. Results Eighty questionnaires were collected (100%). (1) There were 0 to 25 Kampo class meetings during the 6 years of medical school. At least one Kampo class was conducted at 98% of the schools, ≥4 at 84%, ≥8 at 44%, and ≥16 at 5%. Distribution of classes was 19% and 57% for third- and fourth-year students, respectively. (2) Only 29% of schools employed full-time Kampo medicine instructors. (3) Medicine was taught on the basis of traditional Japanese Kampo medicine by 81% of the schools, Chinese medicine by 19%, and Western medicine by 20%. (4) Textbooks were used by 24%. (5) Seventy-four percent considered using standardized textbooks. (6) Thirty-three percent provided faculty development programmes. (7) Regarding course contents, “characteristics” was selected by 94%, “basic concepts” by 84%, and evidence-based medicine by 64%. (8) Among the problems to be solved promptly, curriculum standardization was selected by 63%, preparation of simple textbooks by 51%, and fostering instructors responsible for Kampo education by 65%. Conclusions Japanese medical schools only offer students a short time to study Kampo medicine, and the impetus to include Kampo medicine in their

Background Little is known about the socioeconomic differences in health-related behaviours in Japan. The present study was performed to elucidate the effects of individual and regional socioeconomic factors on selected health risk behaviours among Japanese adults, with a particular focus on regional variations. Methods In a nationally representative sample aged 25 to 59 years old (20,030 men and 21,076 women), the relationships between six risk behaviours (i.e., current smoking, excessive alcohol consumption, poor dietary habits, physical inactivity, stress and non-attendance of health check-ups), individual characteristics (i.e., age, marital status, occupation and household income) and regional (N = 60) indicators (per capita income and unemployment rate) were examined by multilevel analysis. Results Divorce, employment in women, lower occupational class and lower household income were generally associated with a higher likelihood of risk behaviour. The degrees of regional variation in risk behaviour and the influence of regional indicators were greater in women than in men: higher per capita income was significantly associated with current smoking, excessive alcohol consumption, stress and non-attendance of health check-ups in women. Conclusion Individual lower socioeconomic status was a substantial predictor of risk behaviour in both sexes, while a marked regional influence was observed only in women. The accumulation of risk behaviours in individuals with lower socioeconomic status and in women in areas with higher income, reflecting an urban context, may contribute to their higher mortality rates.

Previous space research conducted during short-term flight experiments and long-term environmental monitoring on board orbiting space stations suggests that the relationship between humans and microbes is altered in the crewed habitat in space. Both human physiology and microbial communities adapt to spaceflight. Microbial monitoring is critical to crew safety in long-duration space habitation and the sustained operation of life support systems on space transit vehicles, space stations, and surface habitats. To address this critical need, space agencies including NASA (National Aeronautics and Space Administration), ESA (European Space Agency), and JAXA (Japan Aerospace Exploration Agency) are working together to develop and implement specific measures to monitor, control, and counteract biological contamination in closed-environment systems. In this review, the current status of microbial monitoring conducted in the International Space Station (ISS) as well as the results of recent microbial spaceflight experiments have been summarized and future perspectives are discussed.

Xeroderma pigmentosum (XP) is a rare autosomal recessive hereditary disease. Patients with XP have severe hypersensitivity to sunlight, resulting in skin cancers, and some patients have neurological symptoms. In Japan, XP complementation group A (XP-A) is the most common form, and it is associated with severe neurological symptoms. We performed a nationwide survey on XP to determine the present status of XP in Japan. The distribution of complementation groups in Japan was considerably different from that in other countries, but there was a higher frequency in group A and the variant type, which is similar to previous reports in Japan. Basal cell carcinoma was the most frequent skin cancer that patients with XP developed, followed by squamous cell carcinoma and malignant melanoma. The frequency of these skin cancers in patients with XP-A has decreased, and these skin cancers have been occurring in much older people than those previously observed. Diagnosing XP in patients at younger ages seems to encourage patients and their parents to use sun protection, which helps prevent skin cancer. We also created a tentative scale for classifying the severity of XP, and we evaluated the neurological symptoms of XP-A using this severity scale. Our classification correlated well with patients' age, suggesting that it may be useful and feasible in clinical practice to assess the progression of symptoms of each patient with XP and evaluate the effects of treatment in the future. © 2016 John Wiley & Sons A/S.

Women have accounted for over 30% of new medical students since 1995 in Japan. Establishing support systems for women surgeons to continue their work is a major issue in Japan. Mentorship can be one of the most effective means to help women surgeons to continue their work. The purpose of this study was to clarify the current status of mentorship among Japanese women surgeons and to discuss the role of mentors for women surgeons. Invitation letters were sent to all female members of the Japan Association of Women Surgeons in April 2011. An 84-item questionnaire survey was sent to those who agreed to participate in this study via the internet. Fifty-five surgeons participated in this study, a response rate of 48.7%. Sixty-seven percent of respondents found it difficult to continue in their job; 85% thought mentorship was necessary for women surgeons to progress in their careers; and 84% reported that they already had a mentor. Respondents thought that a mentor helped them to advance their clinical career, to stay in their job, and to provide moral support. However, mentors appeared to be less useful in helping them to advance their research career, to network, to increase their status, and to achieve a work-life balance. This study revealed areas where mentors appeared to be less helpful to women surgeons. The survey gave an indication of how to help improve and develop the career and personal life of women surgeons in Japan.

Socioeconomic status (SES) factors such as employment, educational attainment, income, and marital status can affect the health and well-being of the general population and have been associated with the prevalence of chronic kidney disease (CKD). However, no studies to date in Japan have reported on the prognosis of patients with CKD with respect to SES. This study aimed to investigate the influences of employment and education level on mortality and hospitalization among maintenance hemodialysis (HD) patients in Japan. Data on 7974 HD patients enrolled in Dialysis Outcomes and Practice Patterns Study phases 1-4 (1999-2011) in Japan were analysed. Employment status, education level, demographic data, and comorbidities were abstracted at entry into DOPPS from patient records. Mortality and hospitalization events were collected during follow-up. Patients on dialysis < 120 days at study entry were excluded from the analyses. Cox regression modelled the association between employment and both mortality and hospitalization among patients < 60 years old. The association between education and outcomes was also assessed. The association between patient characteristics and employment among patients < 60 years old was assessed using logistic regression. During a median follow-up of 24.9 months (interquartile range, 18.4-32.0), 10% of patients died and 43% of patients had an inpatient hospitalization. Unemployment was associated with mortality (hazard ratio [HR] = 1.57; 95% confidence interval [CI]: 1.05-2.36) and hospitalization (HR = 1.25; 95% CI: 1.08-1.44). Compared to patients who graduated from university, patients with less than a high school (HS) education and patients who graduated HS with some college tended to have elevated mortality (HR = 1.41; 95% CI, 1.04-1.92 and HR = 1.36; 95% CI: 1.02-1.82, respectively) but were not at risk for increased hospitalizations. Factors associated with unemployment included lower level of education, older age, female gender, longer

Sweetpotato ( Ipomoeae batatas (L.) Lam.) is an important food crop affected by several pests throughout the world, especially in tropical, subtropical, and temperate regions. Although Japan is relatively free from many serious sweetpotato pests, some pests, especially soil-borne pathogens, viruses, and insects such as plant-parasitic nematodes and weevils, cause severe damage in Japan. In this review, we describe the current status and management options for sweetpotato pests and diseases in Japan and review research related to sweetpotato breeding that can promote resistance to these problems. Furthermore, we describe methods to evaluate resistance to pests and disease used in sweetpotato breeding at the National Agriculture and Food Research Organization (NARO).

To assess the relationship between socioeconomic status (SES) and complications of type 2 diabetes among young adults in Japan. A cross-sectional study. Outpatient wards of 96 member hospitals and clinics of the Japan Federation of Democratic Medical Institutions. A total of 782 outpatients with type 2 diabetes (525 males, 257 females), aged 20-40 years as of March 31, 2012. After excluding 110 participants whose retinopathy diagnosis was in question, 672 participants were analyzed. We examined the relations between SES (educational level, income, type of public healthcare insurance, and employment status) and diabetes complications (retinopathy and nephropathy) using a multivariate logistic regression analysis. The prevalence of type 2 diabetic retinopathy was 23.2%, while that of nephropathy was 8.9%. The odds of having retinopathy were higher among junior high school graduates (OR 1.91, 95% CI 1.09-3.34), patients receiving public assistance (OR 2.19, 95% CI 1.20-3.95), and patients with irregular (OR 1.72, 95% CI 1.03-2.86) or no employment (OR 2.23, 95% CI 1.36-3.68), compared to those with a higher SES, even after covariate adjustment (e.g., age, gender, body mass index). Similarly, the odds of having nephropathy were higher among patients with middle (OR 3.61, 95% CI 1.69-8.27) or low income levels (OR 2.53, 95% CI 1.11-6.07), even after covariate adjustment. Low SES was associated with a greater likelihood of type 2 diabetes complications in young adults. These findings suggest the necessity of health policies that mitigate socioeconomic disparity and thereby reduce the prevalence of diabetic complications.

In 1987, a group infection of hepatitis in patients receiving a contaminated fibrinogen product was first reported to the Japanese regulatory agency. Eventually, this serious drug incident involved more than 10,000 cases of infection. In response, the Government of Japan established a responding inspection committee in 2008 to make recommendations for the restructuring of drug regulatory administration. The final report was issued in 2010. One agenda item of this restructuring was the improvement of drug-related safety risk communications. Our research group on drug safety risk communications, which is funded by the Government of Japan, surveyed pharmaceutical companies regarding their perspective on current risk communications. The survey was conducted using an anonymous questionnaire developed for this study which included the three operational domains of targets, contents, and measures of drug risk communication. Fifty-two of the 74 member companies of the Post-marketing Surveillance Subcommittee of the Japan Pharmaceutical Manufacturer's Association participated, and this response rate of more than 70% was considered sufficient to ensure the external validity of the survey results. Results showed that the most highly prioritized aspect of risk messaging was the strength of evidence, and that outcome evaluation of risk communication gained recognition. Further, while physicians and pharmacists were the most prioritized communication targets, pharmacovigilance departments devoted the most resources to regulators, at more than 30%. The Internet was recognized as a useful public source of risk information, whereas Drug Guides for Patients delivered on the web were considered under-recognized. Further discussion of these results with the aim of enhancing the restructuring of the Japanese drug regulatory administration system are warranted.

The two main goals of this research were: (1) To clarify the current state of collaboration among municipal public health nurses throughout Japan (referred to collectively as "Public Health Nurses"); and (2) To identify personal factors that separate Public Health Nurses who collaborate frequently from those who do not, and to clarify the characteristics of relevant interventions. The author believes that the results of this study should be valuable in demonstrating specific methodologies related to the ability of Public Health Nurses the ability to execute collaborative activities. Before conducting the main survey, a preliminary survey was performed to determine the affiliate divisions for Public Health Nurses employed by all of the 3,190 municipalities in Japan. Based on this survey, we gained an understanding of factors such as the number of Public Health Nurses and their places of employment. Next, during December 2003 to August 2004, we carried out a questionnaire survey by post to the 21,631 Public Health Nurses in Japan who had been identified through the preliminary survey. Survey items included: the Public Health Nurse's gender, age, position, most recent academic history, total years of work, number of years working with the current employer, affiliated division, types of tasks undertaken, status of execution of those tasks, and collaborative activities, as well as specialists institutions and organizations involved in such collaboration. Data were gathered from 13,024 Public Health Nurses, which represents roughly 80% of the Public Health Nurses in Japan. First, regarding collaboration, links with health and medical institutions, health centers, and other government institutions appeared active, but this was not the case for social welfare facilities for the physically or mentally disabled. Furthermore, although the subjects collaborated with Public Health Nurses from other institutions, as well as with government administrators and doctors, there was

Purpose: To recognize the current status of stereotactic body radiotherapy (SBRT) in Japan, using a nationwide survey conducted by the Japan 3-D Conformal External Beam Radiotherapy Group. Methods and Materials: The questionnaire was sent by mail to 117 institutions. Ninety-four institutions (80%) responded by the end of November 2005. Fifty-three institutions indicated that they have already started SBRT, and 38 institutions had been reimbursed by insurance. Results: A total of 1111 patients with histologically confirmed lung cancer were treated. Among these patients, 637 had T1N0M0 and 272 had T2N0M0 lung cancer. Metastatic lung cancer was found in 702 and histologicallymore » unconfirmed lung tumor in 291 patients. Primary liver cancer was found in 207 and metastatic liver cancer in 76 patients. The most frequent schedule used for primary lung cancer was 48Gy in 4 fractions at 22 institutions (52%), followed by 50Gy in 5 fractions at 11 institutions (26%) and 60Gy in 8 fractions at 4 institutions (10%). The tendency was the same for metastatic lung cancer. The average number of personnel involved in SBRT was 1.8 radiation oncologists, including 1.1 certified radiation oncologists, 2.8 technologists, 0.7 nurses, and 0.6 certified quality assurance personnel and 0.3 physicists. The most frequent amount of time for treatment planning was 61-120min, for quality assurance was 50-60min, and for treatment was 30min. There were 14 (0.6% of all cases) reported Grade 5 complications: 11 cases of radiation pneumonitis, 2 cases of hemoptysis, and 1 case of radiation esophagitis. Conclusion: The current status of SBRT in Japan was surveyed.« less

As of mid-2014, the main organizations of the earthquake (EQ hereafter) prediction program, including the Seismological Society of Japan (SSJ), the MEXT Headquarters for EQ Research Promotion, hold the official position that they neither can nor want to make any short-term prediction. It is an extraordinary stance of responsible authorities when the nation, after the devastating 2011 M9 Tohoku EQ, most urgently needs whatever information that may exist on forthcoming EQs. Japan's national project for EQ prediction started in 1965, but it has made no success. The main reason for no success is the failure to capture precursors. After the 1995 Kobe disaster, the project decided to give up short-term prediction and this stance has been further fortified by the 2011 M9 Tohoku Mega-quake. This paper tries to explain how this situation came about and suggest that it may in fact be a legitimate one which should have come a long time ago. Actually, substantial positive changes are taking place now. Some promising signs are arising even from cooperation of researchers with private sectors and there is a move to establish an "EQ Prediction Society of Japan". From now on, maintaining the high scientific standards in EQ prediction will be of crucial importance.

The purpose of this research is to elucidate the actual status of Infectious Diseases (ID) Fellowship programs in Japan to improve them further. We conducted qualitative interviews with infectious diseases fellows and his/her faculty consultants from 10 institutions providing ID Fellowships in Japan. We qualitatively analysed the data to delineate the actual status of each program and the fellowship program policies overall, and to identify measures for further improvement. The interviews revealed that there are largely two kinds of ID fellowships; ID programs entirely devoting full time to infectious diseases, and programs that are subordinate concepts of other subspecialties, where only a portion of hours were devoted to ID. Some institutions did not even have an ID department. Time spent by the faculty consultants on fellows also varied among programs. The desire for improvement also varied among interviewees; some being happy with the current system while others demanded radical reform. Even though there are many ID fellowship programs in Japan, the content, quality, and concepts apparently vary among programs. The perceptions by interviewees on the educational system differed, depending on the standpoints they have on ID physicians. There probably needs to be a coherency in the provision of ID fellowship programs so that fellows acquire competency in the subspecialty with sufficient expertise to act as independent ID specialists. Further studies are necessary for the improvement of ID subspecialty training in Japan.

The hooded crane is designated as an endangered species. The cranes breed primarily in wetlands in southeast Russia and China in summer. Most of the hooded crane population winters in the Izumi plain in Japan. It is difficult to know the contamination status of their habitat because of their vast breeding area. We determined the levels of Cd, Pb, As, (total) Hg, Se, Zn, and Cu in the liver, kidney, and muscle of hooded cranes that were found dead in Izumi in the periods 2003-2006 and 2014-2015 compared with the levels in red-crowned cranes in Hokkaido, Japan, as the only cranes in which these elements had been studied extensively. There were no notable differences between levels of the seven elements in the two periods. Overall, tissue levels of the elements examined in hooded cranes were comparable to those in red-crowned cranes except for Hg and Se. Tissue levels of Hg and Se were clearly lower in hooded cranes than in red-crowned cranes that were found dead from 2000. One lead poisoning case was confirmed. The results suggest that Hooded cranes wintering in Izumi are not extensively contaminated with the seven elements examined.

Recent trends for drug lag in clinical development of oncology drugs in Japan: does the oncology drug lag still exist in Japan?

This study exhaustively and historically investigated the status of drug lag for oncology drugs approved in Japan. We comprehensively investigated oncology drugs approved in Japan between April 2001 and July 2014, using publicly available information. We also examined changes in the status of drug lag between Japan and the United States, as well as factors influencing drug lag. This study included 120 applications for approval of oncology drugs in Japan. The median difference over a 13-year period in the approval date between the United States and Japan was 875 days (29.2 months). This figure peaked in 2002, and showed a tendency to decline gradually each year thereafter. In 2014, the median approval lag was 281 days (9.4 months). Multiple regression analysis identified the following potential factors that reduce drug lag: "Japan's participation in global clinical trials"; "bridging strategies"; "designation of priority review in Japan"; and "molecularly targeted drugs". From 2001 to 2014, molecularly targeted drugs emerged as the predominant oncology drug, and the method of development has changed from full development in Japan or bridging strategy to global simultaneous development by Japan's taking part in global clinical trials. In line with these changes, the drug lag between the United States and Japan has significantly reduced to less than 1 year.

Several studies have shown that parity is associated with oral health problems such as tooth loss and dental caries. In Japan, however, no studies have examined the association. The purpose of this study was to determine whether parity is related to dentition status, including the number of teeth present, dental caries and filled teeth, and the posterior occlusion, in a Japanese population by comparing women with men. A total of 1,211 subjects, who participated both in the Japan Public Health Center-Based (JPHC) Study Cohort I in 1990 and the dental survey in 2005, were used for the study. Information on parity or number of children was collected from a self-completed questionnaire administered in 1990 for the JPHC Study Cohort I, and health behaviors and clinical dentition status were obtained from the dental survey in 2005. The association between parity or number of children and dentition status was analyzed, by both unadjusted-for and adjusted-for socio-demographic and health behavioral factors, using a generalized linear regression model. Parity is significantly related to the number of teeth present and n-FTUs (Functional Tooth Units of natural teeth), regardless of socio-demographic and health behavioral factors, in female subjects. The values of these variables had a significantly decreasing trend with the rise of parity: numbers of teeth present (p for trend = 0.046) and n-FTUs (p for trend = 0.026). No relationships between the number of children and dentition status were found in male subjects. Higher-parity women are more likely to lose teeth, especially posterior occluding relations. These results suggest that measures to narrow the discrepancy by parity should be taken for promoting women's oral health. Delivery of appropriate information and messages to pregnant women as well as enlightenment of oral health professionals about dental management of pregnant women may be an effective strategy.

Energy harvested from surface ocean waves and tidal currents has the potential to be a significant source of green energy, particularly for countries with extensive coastlines such as Japan. As part of a larger marine renewable energy project*, The University of Tokyo (in cooperation with JAMSTEC) has conducted a state-of-the-art wave resource assessment (with uncertainty estimates) to assist with wave generator site identification and construction in Japan. This assessment will be publicly available and is based on a large-scale NOAA WAVEWATCH III (version 4.18) simulation using NCEP and JAMSTEC forcings. It includes several key components to improve model skill: a 20-year simulation to reduce aleatory uncertainty, a four-nested-layer approach to resolve a 1 km shoreline, and finite-depth and current effects included in all wave power density calculations. This latter component is particularly important for regions near strong currents such as the Kuroshio. Here, we will analyze the different wave power density equations, discuss the model setup, and present results from the 20-year assessment (with a focus on the role of wave-current interactions). Time permitting, a comparison will also be made with simulations using JMA MSM 5 km winds. *New Energy and Industrial Technology Development Organization (NEDO): "Research on the Framework and Infrastructure of Marine Renewable Energy; an Energy Potential Assessment"

We investigated lateral profiles of 228Ra (half-life; 5.75 years) activity and 228Ra/226Ra (1600 years) activity ratio using 241 surface water samples collected in/around the Sea of Japan and the East China Sea (ECS) during June-October of 2009-2014. In the ECS, the 228Ra/226Ra ratio in the surface waters exhibited markedly wide variation (<0.05-3.5) in June, predominantly reflecting the mixing between the 228Ra-rich continental shelf water and the 228Ra-depleted Kuroshio Current water. In July, the surface waters of the central Sea of Japan (135-138°E) became separated into three currents: the Offshore Branch of the Tsushima Warm Current (OBTWC) (228Ra/226Ra =0.7-1.2) at 39-41°N, the Coastal Branch of the TWC (CBTWC) ( 0.7) on the southern side, and sub-Arctic Current ( 0.7) on the northern side. From the central to northeastern Sea of Japan, the 228Ra/226Ra ratio at the surface (0.8-1.0) was within a range between that of the CBTWC and OBTWC. The fraction of continental shelf water in the CBTWC, OBTWC, and in their combined current was estimated to be 11-16%, 8%, and 10-11%, respectively.

To contribute to evidence-based policy decision making for national cancer control, we conducted a systematic assessment to estimate the current burden of cancer attributable to known preventable risk factors in Japan in 2005. We first estimated the population attributable fractions (PAFs) of each cancer attributable to known risk factors from relative risks derived primarily from Japanese pooled analyses and large-scale cohort studies and the prevalence of exposure in the period around 1990. Using nationwide vital statistics records and incidence estimates, we then estimated the attributable cancer incidence and mortality in 2005. In 2005, ≈ 55% of cancer among men was attributable to preventable risk factors in Japan. The corresponding figure was lower among women, but preventable risk factors still accounted for nearly 30% of cancer. In men, tobacco smoking had the highest PAF (30% for incidence and 35% for mortality, respectively) followed by infectious agents (23% and 23%). In women, in contrast, infectious agents had the highest PAF (18% and 19% for incidence and mortality, respectively) followed by tobacco smoking (6% and 8%). In Japan, tobacco smoking and infections are major causes of cancer. Further control of these factors will contribute to substantial reductions in cancer incidence and mortality in Japan.

Medical error involving nurses is a critical issue since nurses' actions will have a direct and often significant effect on the prognosis of their patients. To investigate the significance of nurse health in Japan and its potential impact on patient services, a questionnaire-based survey amongst nurses working in hospitals was conducted, with the specific purpose of examining the relationship between shift work, mental health and self-reported medical errors. Multivariate analysis revealed significant associations between the shift work system, General Health Questionnaire (GHQ) scores and nurse errors: the odds ratios for shift system and GHQ were 2.1 and 1.1, respectively. It was confirmed that both sleep and mental health status among hospital nurses were relatively poor, and that shift work and poor mental health were significant factors contributing to medical errors.

Japan is setting the pace among aging societies of the world. In 2005, Japan became the country with the highest proportion of elderly persons in the world. To deal with the accelerated ageing population and with an increased demand for long-term care services, in April 2000 the Japanese government introduced a mandatory social Long-Term Care Insurance System (LTCI), making long-term care services a universal entitlement for elderly. Overseas literature suggests that the effectiveness of a home visiting program is uncertain in terms of preventing a decline in the functional status of elderly individuals. In Japan, many studies regarding factors associated with LTC service utilization have been conducted, however, limited evidence about the effect of LTC services on the progression of recipient disability is available. Data were obtained from databases of the LTC insurer of City A. To examine the effect of in-home and community-based services on disability status of recipients, a survival analysis in a cohort of moderately disabled elderly people, was conducted. The mean age of participants was 81 years old, and females represented 69% of the participants. A decline or an improvement in functional status, was observed in 43% and 27% of the sample, respectively. After controlling for other variables, women had a significantly greater probability of improving their functional status during all phases of the observation period. The use of "one service" and the amount of services utilized (days/month), were marginally (p = < 0.10) associated with a greater probability of improving their functional status at 12 months into the observation period. The observed effects of in-home and community-based services on disability transition status were considered fairly modest and weak, in terms of their ability to improve or to prevent a decline in functional status. We suggest two mechanisms to explain these findings. First, disability transition as a measure of disability

Inflammatory Bowel Disease (IBD) constitutes a huge burden for patients and studies show that IBD patients have difficulties remaining in employment. Because there is no data about the unemployment of IBD patients in Japan. We surveyed a representative sample of 1068 Japanese IBD patients regarding their employment status. We found that the labor force participation rate is lower and unemployment higher for patients with IBD compared to the general population. Factors associated with unemployment in the IBD sample are older age, female gender, and the prevalence of depression. IBD constitutes a high burden for patients in Japan regarding employment outcome.

We examined the prevalence of chronic obstructive pulmonary disease (COPD) diagnosed and at-risk status, and public awareness of COPD among adults in Japan, as well as respondent characteristics and health outcomes compared with controls. Regression models used 2012 National Health and Wellness Survey in Japan data to compare COPD-diagnosed, at-risk, and healthy adults (aged ≥18) on demographics, health behaviors, health-related quality of life (HRQoL), productivity and healthcare resource use. Among n = 29,978 respondents, diagnosed COPD prevalence was 0.9%; 26.9% were at-risk. Relative to controls, those at-risk and diagnosed with COPD had significantly greater healthcare resource use, with lower productivity and HRQoL. Fewer than 20% of respondents were aware of COPD. Over 25% of adult Japanese respondents were at-risk for COPD and had health outcomes impairments relative to controls. Efforts to increase awareness among the general public are needed.

As for the Sealed Radioactive Source currently used in Japan, many of them are imported from overseas. The U.S., Canada, Germany, the Netherlands, Belgium and Czech Republic are the main exporting States. Many of disused sealed radioactive sources are being returned to exporting States. The sealed radioactive sources which cannot be returned to exporting States are appropriately kept in the domestic storage facility. So, there are not main problem on the long term management of disused sealed radioactive sources in Japan. However, there are some difficulties on repatriate. One is reservation of a means of transport. The sea mail whichmore » conveys radioactive sources owing to reduction of movement of international cargo is decreasing in number. And there is a denial of shipment. Other one is that the manufacturer has already resigned from the work and cannot return disused sealed radioactive sources, or a manufacturer cannot specify and disused sources cannot be returned. The disused sealed radioactive source which cannot be repatriated is a little in term of radioactivity. As for the establishment of national measure of final disposal facility for disused sealed radioactive sources, in Japan, it is not yet installed with difficulty. Since there are many countries for which installation of a final disposal facility for disused sealed radioactive sources is difficult, the source manufacture country should respond positively to return the source which was manufactured and sold in the past.

radioactive contamination. Monitoring of radioactive materials in food products in the prefectures has been mainly conducted before shipment to restrict the distribution of radio-contaminated foods. Between March 2011 and March 2012, 133,832 tests of non-commercial and commercial products were conducted, and 1,204 tests (0.9%) were found to violate the provisional standards. Since April 2012, 278,275 tests were conducted, and 2,372 tests (0.9%) were found to violate the revised standards. MHLW assessment of representative market baskets of foodstuffs at 15 locations throughout Japan between February and March 2014 found very low estimated dietary intake of radioactive cesium (0.0007-0.019 mSv/year), as did assessments of the contents of an average day's food. Monitoring of fisheries products in coastal areas affected by the nuclear accident found very limited and declining radio-contamination of live fish outside of Fukushima prefecture. Fisheries monitoring is of limited geographical scope and covers only certain fishes. Area-specific bans on production and distribution have been effective in preventing radioactive contamination in the Japanese food market. Currently there is no major concern about radioactive cesium concentrations in retail foodstuffs in Japan, and very low levels of contamination at the production and wholesale stage. However, because the residue limits and food safety policies were revised on an ad hoc, emergency basis after the nuclear accident, the monitoring procedure needs to be reviewed based on objective and scientifically rational criteria. A transparent and objective scientific framework is needed for prioritizing foodstuffs for inspection and revising Prefecture-specific restrictions. Monitoring of fishes and other seafood products in the wild should be regularized and the information made more publicly accessible, and monitoring activities expanded to identify foodstuffs that are no longer a food safety risk.

The objective of this study is to investigate the cross-cultural relationship between depressive state and subjective economic status, as well as subjective quality of life (QOL) and activities of daily living (ADL) among elderly people in communities in Japan, Taiwan, and Korea. We studied 595 subjects aged 65 years or older in three Asian communities (261 subjects in T town in Japan, 164 in D town in Taiwan, and 170 in H town in Korea). The Geriatric Depression Scale-15, a self-rating questionnaire assessing ADL, subjective QOL, social situations, and past and current medical status, was used. Depression of the elderly was associated with dependence in basic ADL, subjective QOL, and subjective sense of low economic status. After adjusting for the effects of age, sex, and basic ADL, subjective sense of low economic status was closely associated with depression in community-living elderly people in all three communities in Asia. In conclusion, absolute and objective economic status is an important contributing factor to depressive state or psychosocial deterioration, however, we should pay more attention to the roles of perception of low economic status in determining depressive state in community-dwelling elderly people.

Impact of gender-based career obstacles on the working status of women physicians in Japan.

Nomura, Kyoko; Gohchi, Kengo

2012-11-01

Research has shown that women physicians work fewer hours and are more likely to become inactive professionally and to switch to part-time labor, compared with their male counterparts. The published literature suggests that a gender disparity still exists in medicine which may decrease work motivation among women physicians. The authors investigated whether the experience and the perception of gender-based career obstacles among women physicians in Japan are associated with their working status (i.e., full-time vs. part-time). The present cross-sectional study is based on surveys of alumnae from 13 private medical schools in Japan conducted between June 2009 and May 2011. Of those who agreed to participate in this study, 1684 completed a self-administered questionnaire (overall response rate 83%). Experience of gender-based obstacles was considered affirmative if a woman physician had been overlooked for opportunities of professional advancement based on gender. Perception of gender-based obstacles referred to the self-reported degree of difficulty of promotion and opportunities for a position in higher education. Approximately 20% of the study participants responded that they experienced gender-based obstacles while 24% answered that they were not sure. The scores for perception of gender-based career obstacles were statistically higher among part-time workers compared with full-time workers (mean difference = 1.20, 95% CI: 0.39-2.00). Adjusting for age, marital status, the presence of children, workplace, board certification, holding a PhD degree, overall satisfaction of being a physician, and household income, stepwise logistic regression models revealed that physicians with the strongest perception of gender-based career obstacles were more likely to work part-time rather than full-time (OR, 0.59; 95% CI: 0.40-0.88). Although the experience of gender-based obstacles was not associated with working status among women physicians, the results demonstrated that a

The Great East Japan Earthquake and devastating Tsunami caused irreparable damage on the northeastern coast of Japan. This study aimed to examine the influencing factors of "Living environment" and "Working status" on low back pain for the survivors of the earthquake evaluated by a self-report questionnaire. Between 2011 and 2013, survivors replied to the self-report questionnaire, and 986 people consented to join this study. The living environment was divided into 3 categories (1. Living in the same house as before the earthquake, 2. Living in a safe shelter or temporary small house, 3. Living in a house of relatives or apartment house) and working status was divided into 5 categories (1. Unemployed before the earthquake, 2. Unemployed after the earthquake, 3. Decrease in income, 4. Different occupation after the earthquake, 5. The same occupation as before the earthquake). Age, gender, living areas, past history of arthritis, arthropathy, osteoporosis, sleep disturbance, psychological distress, and economic status were considered as confounding factors. Generalized estimating regression models with logit link function were used because outcome variables are repeatedly measured and binomial. We evaluated the correlation between the presence/severity of low back pain over time and housing status/working status at 1 year after the earthquake. There were no significant differences between age, gender, living areas, working status, or living environment before or after the earthquake. There was no significant difference in the risk of having low back pain in living environment or gender. There was significant difference in the risk of having low back pain in those with "Decrease in income" (OR = 1.93, 95% CI = 1.23-3.03) and "The same occupation as before the earthquake" (OR = 1.67, 95% CI = 1.1-2.52). Though living environment has little effect, "Decrease in income" and "The same occupation as before the earthquake" have strong influences on low back pain

Marginal regression approach for additive hazards models with clustered current status data.

PubMed

Su, Pei-Fang; Chi, Yunchan

2014-01-15

Current status data arise naturally from tumorigenicity experiments, epidemiology studies, biomedicine, econometrics and demographic and sociology studies. Moreover, clustered current status data may occur with animals from the same litter in tumorigenicity experiments or with subjects from the same family in epidemiology studies. Because the only information extracted from current status data is whether the survival times are before or after the monitoring or censoring times, the nonparametric maximum likelihood estimator of survival function converges at a rate of n(1/3) to a complicated limiting distribution. Hence, semiparametric regression models such as the additive hazards model have been extended for independent current status data to derive the test statistics, whose distributions converge at a rate of n(1/2) , for testing the regression parameters. However, a straightforward application of these statistical methods to clustered current status data is not appropriate because intracluster correlation needs to be taken into account. Therefore, this paper proposes two estimating functions for estimating the parameters in the additive hazards model for clustered current status data. The comparative results from simulation studies are presented, and the application of the proposed estimating functions to one real data set is illustrated. Copyright © 2013 John Wiley & Sons, Ltd.

Occupation could affect the distribution of smoking status of workers, and the success of smoking cessation among workers depends partly on worksite conditions. Blue collar workers have been identified as a high-risk group for smoking. The aim of the present study was to examine trends in smoking rates among urban civil servants in Japan according to occupational categories. Subjects were urban civil servants aged 30-59 years. They annually reported smoking status in a questionnaire in a worksite health check-up each year from 2004 to 2011. Urban civil servants reported substantially lower current smoking rates than national smoking rates in Japan (20.2%, 23.8%, and 27.0% for males in their 30s, 40s, and 50s and 2.4%, 6.3%, and 9.5% for females, respectively, in 2011). In analysis by occupational categories, current smoking rates declined among all groups except female white collar workers in their 50s. The current and persistent smoking rates (number of current smokers/[number of ex-smokers and current smokers]) among blue collar workers were higher than those among white collar workers at almost all time points in all age and gender groups. This study found relatively lower current smoking rates among urban civil servants than the national average and higher current and persistent smoking rates in blue collar workers than in white collar workers among them. These results would help to make suitable worksite smoking cessation policies for each occupational category.

Gallid herpesvirus 2 (GaHV-2) causes malignant lymphomas in chickens (Marek's disease, MD). Although MD is controlled through vaccination efforts, field isolates of GaHV-2 have increased in virulence worldwide and even cause MD in vaccinated chickens. GaHV-2 strains are classified into four categories (mild, virulent, very virulent and very virulent +) based on the virulence exhibited in experimental infection in unvaccinated or MD-vaccinated susceptible chickens. Although MD cases are sporadically reported in Japan, the recent field strains of GaHV-2 in Japan have not been characterized. During isolation of recent field strains by using primary chicken kidney cell cultures, a method classically used for GaHV-2 isolation, vaccine strains were simultaneously isolated. Therefore, it is necessary to separate vaccine strains to characterize the virulence and pathogenicity of the GaHV-2 strains currently distributed in Japan. In this study, we prepared cell suspensions from the spleens of MD-symptomatic chickens, inoculated day-old-chicks and isolated GaHV-2 strains by primary chicken kidney cell cultures at 2-3 weeks post inoculation. The isolated strains were passaged several times on chicken embryo fibroblast cells, and PCR analysis revealed that the isolated strains were not contaminated with vaccine strains. Moreover, the contaminant vaccine strains were completely removed by the purification of plaques observed in chicken kidney cells. These procedures are necessary to isolate GaHV-2 field strains from vaccine strains in order to carry out future studies to characterize these strains and glean insights into GaHV-2 virulence and pathogenicity.

This paper summarizes the current and anticipated use of the thermal-hydraulic and neutronic codes for the BWR transient and accident analyses in Japan. The codes may be categorized into the licensing codes and the best estimate codes for the BWR transient and accident analyses. Most of the licensing codes have been originally developed by General Electric. Some codes have been updated based on the technical knowledge obtained in the thermal hydraulic study in Japan, and according to the BWR design changes. The best estimates codes have been used to support the licensing calculations and to obtain the phenomenological understanding ofmore » the thermal hydraulic phenomena during a BWR transient or accident. The best estimate codes can be also applied to a design study for a next generation BWR to which the current licensing model may not be directly applied. In order to rationalize the margin included in the current BWR design and develop a next generation reactor with appropriate design margin, it will be required to improve the accuracy of the thermal-hydraulic and neutronic model. In addition, regarding the current best estimate codes, the improvement in the user interface and the numerics will be needed.« less

Rabies was eliminated in Japan over 50 years ago; however, the recent increase in the movement of humans and animals across the world highlights the potential threat of disease reentry into the country. The immune status against rabies among the dog population in Japan is not well known; thus, the purpose of this study was to estimate the prevalence of dogs with effective immunity from the vaccination history using a web-based survey. We found that 76.9% (95% confidence interval, 75.8-78.1) of dogs in this study population belonged to the population in which 90% were assumed to have the internationally accepted antibody titer. We showed that dogs taken less frequently for walks were less likely to be vaccinated. Additionally, the frequency of encounters with other dogs during walks and the number of individuals in households were associated with vaccination history. To our knowledge, this study is the first report estimating the prevalence of dogs in Japan with effective immunity against rabies. Further, we identified the population with low vaccination coverage as well as the heterogeneous characteristics of vaccination history among the dog population. These findings contribute to the implementation of an efficient strategy for improving the overall vaccination coverage in Japan and the development of a quantitative risk assessment of rabies.

The status of preimplantation genetic diagnosis in Japan: a criticism.

PubMed

Munné, Santiago; Cohen, Jacques

2004-09-01

Advances in preimplantation genetic diagnosis (PGD) are occurring worldwide. New clinics specializing in this approach to the control of disease genes or imbalanced chromosome numbers in human preimplantation embryos continue to increase. One exception is Japan, where the Japanese Society of Obstetrics and Gynecology disapproves of this practice because it discriminates against people with genetic abnormalities. Yet, some doctors there wish to introduce this method to help their couples to improved forms of IVF. This paper stresses the rights of patients to have a healthy baby, if necessary by the use of PGD. It argues against prohibition, since it complements the current nature of prenatal diagnosis and avoids the need for abortions in case of afflicted embryos. Consideration is also given to other attempts at restriction that have failed.

An Annual Cycle Of Currents Around Tsushima Island And Resulting Inflow Conditions In The Sea Of Japan

NASA Astrophysics Data System (ADS)

Perkins, H.; Teague, W. J.; Chang, K.-I.; Suk, M.-S.; Lee, J.-C.; Book, J. W.; Jacobs, G. A.

A ten-month long time series of current measurements has been made on two sections across Korea/Tsushima Strait, thus revealing most of an annual cycle of the Tsushima Current that flows into the Japan/East Sea. One section is southwest, the other north- east, of Tsushima Island, giving respectively conditions upstream and downstream of the Island. Along the bathymetric slope upstream of the Island, the current consists of a single, broad stream concentrated in mid-channel. Downstream, this single core is found to have separated into two branches, one on each of the Strait. Between these two near-coastal streams, in the apparent wake of the Island, currents are variable and lack a well-defined mean. This separation persisted during all seasons despite vari- ation in total transport by a factor of two, from 3.5 Sv in October 1999 to 1.7 Sv in January 2000, and despite changes from maximum to minimum stratification. Both branches of the divided current were stronger during high transport and weaker during low transport, but since each branch was measured by only one or two moorings, trans- port estimates for the separate branches are not available. Strongest currents occurred at the surface close to the Korean coast near Ulsan in early fall with low-pass surface currents reaching 90 cm/s during October and November. Farther downstream, outside the measurement area, the two branches define the inflow to the Japan/East Sea. The branch along the Japanese coast remains close to the coast. It undergoes strong annual variability but is steady on shorter time scales. The Korean branch of the current also undergoes strong annual changes but experiences very strong variability, especially in winter. This branch is thought to switch between two paths. The first parallels the Ko- rean coast; the second follows bathymetric contours that lead it back to the Japanese coast. A mechanism for switching between these paths is provided by vorticity asso- ciated with bottom intrusions

An 85-year-old Japanese woman presented with infiltrative erythema and ulceration on the extensor surface of her right forearm. Direct microscopic examination demonstrated spherical and morula-like sporangia, while histopathology revealed numerous microorganisms with a mulberry-like appearance in the dermis. Staining of the microorganisms also showed mulberry-like sporangia that resembled the spokes of a wheel. The isolated yeast-like microorganism had been identified as Prototheca wickerhamii genotype 2 in another independent study on the basis of its morphological, biochemical and genetic analysis. This case of protothecosis was recorded in Kyushu, Japan, and oral treatment with itraconazole 200 mg/day for 2 months was effective.

were released for areas at risk of radioactive contamination. Monitoring of radioactive materials in food products in the prefectures has been mainly conducted before shipment to restrict the distribution of radio-contaminated foods. Between March 2011 and March 2012, 133,832 tests of non-commercial and commercial products were conducted, and 1,204 tests (0.9%) were found to violate the provisional standards. Since April 2012, 278,275 tests were conducted, and 2,372 tests (0.9%) were found to violate the revised standards. MHLW assessment of representative market baskets of foodstuffs at 15 locations throughout Japan between February and March 2014 found very low estimated dietary intake of radioactive cesium (0.0007–0.019 mSv/year), as did assessments of the contents of an average day’s food. Monitoring of fisheries products in coastal areas affected by the nuclear accident found very limited and declining radio-contamination of live fish outside of Fukushima prefecture. Fisheries monitoring is of limited geographical scope and covers only certain fishes. Conclusions Area-specific bans on production and distribution have been effective in preventing radioactive contamination in the Japanese food market. Currently there is no major concern about radioactive cesium concentrations in retail foodstuffs in Japan, and very low levels of contamination at the production and wholesale stage. However, because the residue limits and food safety policies were revised on an ad hoc, emergency basis after the nuclear accident, the monitoring procedure needs to be reviewed based on objective and scientifically rational criteria. A transparent and objective scientific framework is needed for prioritizing foodstuffs for inspection and revising Prefecture-specific restrictions. Monitoring of fishes and other seafood products in the wild should be regularized and the information made more publicly accessible, and monitoring activities expanded to identify foodstuffs that are no

The aim of the present study was to examine the associations of current smoking with five other unhealthy lifestyle behaviors among urban civil servants in Japan according to sex and occupational category. The study included 10,232 urban civil servants in Japan who presented for a health check-up in 2011. We analyzed data on anthropometric measurements and self-reported lifestyle factors. Current smokers had a higher BMI than never smokers in white-collar workers, but not in blue-collar workers of both sexes. There were strong associations of current smoking with irregular breakfasting regardless of sex and occupational category. In males, current smokers were less likely to take exercise than ex-smokers in both occupational categories. The associations of current smoking with other unhealthy behaviors were modified by sex and occupational category. These results are useful for understanding the health risks among smokers according to sex and occupational category.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in 2013, and its official Japanese version was published in 2014. The Japanese Government uses classifications from the 10th revision of the I nternational C lassification of D iseases (ICD-10) to categorize disorders and determine treatment fees. However, since the publication of the DSM-III, the use of the DSM system has become prevalent in research and educational settings in Japan. In addition to traditional psychiatry, both the ICD and the DSM are taught by many Japanese medical schools, and virtually all clinical research and trials refer to the DSM to define targeted disorders. Amid the current backdrop in which the reputation of the DSM-5 is being established, the editorial board of P sychiatry and C linical N eurosciences has asked Japanese experts across 12 specialties to examine the structure of the DSM-5, including the following categories: Neurodevelopmental Disorders, Schizophrenia Spectrum Disorders, Major Depression, Bipolar Disorders, Obsessive-Compulsive Disorders, Somatic Symptom Disorder, Eating Disorders, Substance-Related and Addictive Disorders, Gender Dysphoria, and Neurocognitive Disorders. Although opinions were only obtained from these selected experts, we believe that we have succeeded, to a certain extent, in presenting views that are representative of each specialty. © 2016 The Authors.

The international trade in amphibians is believed to have increased the spread of Batrachochytrium dendrobatidis (Bd), the fungal pathogen responsible for chytridiomycosis, which has caused a rapid decline in amphibian populations worldwide. We surveyed amphibians imported into Japan and those held in captivity for a long period or bred in Japan to clarify the Bd infection status. Samples were taken from 820 individuals of 109 amphibian species between 2008 and 2011 and were analyzed by a nested-PCR assay. Bd prevalence in imported amphibians was 10.3% (58/561), while it was 6.9% (18/259) in those in private collections and commercially bred amphibians in Japan. We identified the genotypes of this fungus using partial DNA sequences of the internal transcribed spacer (ITS) region. Sequencing of PCR products of all 76 Bd-positive samples revealed 11 haplotypes of the Bd ITS region. Haplotype A (DNA Data Bank of Japan accession number AB435211) was found in 90% (52/58) of imported amphibians. The results show that Bd is currently entering Japan via the international trade in exotic amphibians as pets, suggesting that the trade has indeed played a major role in the spread of Bd.

The imminent healthcare and emergency care crisis in Japan.

Japan has a universal healthcare system, and this paper describes the reality of the healthcare services provided, as well as current issues with the system. Academic, government, and press reports on Japanese healthcare systems and healthcare guidelines were reviewed. The universal healthcare system of Japan is considered internationally to be both low-cost and effective because the Japanese population enjoys good health status with a long life expectancy, while healthcare spending in Japan is below the average given by the Organization for Economic Corporation and Development (OECD). However, in many regions of Japan the existing healthcare resources are seriously inadequate, especially with regard to the number of physicians and other health professionals. Because healthcare is traditionally viewed as "sacred" work in Japan, healthcare professionals are expected to make large personal sacrifices. Also, public attitudes toward medical malpractice have changed in recent decades, and medical professionals are facing legal issues without experienced support of the government or legal professionals. Administrative response to the lack of resources and collaboration among communities are beginning, and more efficient control and management of the healthcare system is under consideration. The Japanese healthcare system needs to adopt an efficient medical control organization to ease the strain on existing healthcare professionals and to increase the number of physicians and other healthcare resources. Rather than continuing to depend on healthcare professionals being able and willing to make personal sacrifices, the government, the public and medical societies must cooperate and support changes in the healthcare system.

Research that focuses on the relationship between interpersonal conflict at work (i.e., intragroup conflict and intergroup conflict) and depression that also considers differences in socioeconomic status (SES) is limited. The purpose of the current study is to investigate the relationship between interpersonal conflict at work and depression at different levels of SES. A cross-sectional study was conducted with a total of 17,390 males and 2923 females employed in nine factories located in several regions of Japan. These participants were surveyed using a self-administered questionnaire that included self-reported measures of interpersonal conflict at work (intragroup conflict and intergroup conflict), SES (education and occupation), worksite support (supervisor support and coworker support), depression (assessed using the Center for Epidemiologic Studies Depression [CES-D] scale), and other demographic covariates. Those who had scores of 16 + on the CES-D scale (4066 males and 873 females) were classified as experiencing depression. The association of interpersonal conflict with depression was significantly greater among males of a high SES (i.e., higher educational status and non-manual workers) than males of a low SES (i.e., lower educational status and manual workers) after adjusting for demographic variables, supervisor support, and coworker support. More specifically, the association of intergroup conflict with depression was significantly greater among males of a high SES than males of a low SES. However, this pattern was not observed in females. The current study suggests that males of a higher SES are more vulnerable to interpersonal conflict at work in terms of developing depression than males of a lower SES.

The deep-sea crangonid shrimp, Argis lar, is a highly abundant species from the northern Pacific Ocean. We investigated its phylogeographic and demographic structure across the species' extensive range, using mitochondrial DNA sequence variation to evaluate the impact of deep-sea paleoenvironmental dynamics in the Sea of Japan on population histories. The haplotype network detected three distinct lineages with allopatric isolation, which roughly corresponded to the Sea of Japan (Lineage A), the northwestern Pacific off the Japanese Archipelago (Lineage B), and the Bering Sea/Gulf of Alaska (Lineage C). Lineage A showed relatively low haplotype and nucleotide diversity, a significantly negative value of Tajima's D, and a star-shaped network, suggesting that anoxic bottom-water in the Sea of Japan over the last glacial period may have brought about a reduction in the Sea of Japan population. Furthermore, unexpectedly, the distributions of Lineage A and B were closely related to the pathways of the two ocean currents, especially along the Sanriku Coast. This result indicated that A. lar could disperse across shallow straits through the ocean current, despite their deep-sea adult habitat. Bayesian inference of divergence time revealed that A. lar separated into three lineages approximately 1 million years before present (BP) in the Pleistocene, and then had been influenced by deep-sea paleoenvironmental change in the Sea of Japan during the last glacial period, followed by a more recent larval dispersal with the ocean current since ca. 6 kilo years BP.

Chronic heart failure in Japan: implications of the CHART studies.

The prognosis of patients with chronic heart failure (CHF) still remains poor, despite the recent advances in medical and surgical treatment. Furthermore, CHF is a major public health problem in most industrialized countries where the elderly population is rapidly increasing. Although the prevalence and mortality of CHF used to be relatively low in Japan, the disorder has been markedly increasing due to the rapid aging of the society and the Westernization of lifestyle that facilitates the development of coronary artery disease. The Chronic Heart Failure Analysis and Registry in the Tohoku District (CHART)-1 study was one of the largest cohorts in Japan. The study has clarified the characteristics and prognosis of Japanese patients with CHF, demonstrating that their prognosis was similarly poor compared with those in Western countries. However, we still need evidence for the prevention and treatment of CHF based on the large cohort studies or randomized treatment trials in the Japanese population. Since the strategy for CHF management is now changing from treatment to prevention, a larger-size prospective cohort, called the CHART-2 study, has been initiated to evaluate the risk factors of CHF in Japan. This review summarizes the current status of CHF studies in Japan and discusses their future perspectives.

At the annual meeting of the Society of Hair Testing in Vadstena, Sweden in 2006, a committee was appointed to address the issue of guidelines for hair testing and to assess the current status of accreditation amongst laboratories offering drug testing in hair. A short questionnaire was circulated amongst the membership and interested parties. Fifty-two responses were received from hair testing laboratories providing details on the amount and type of hair tests they offered and the status of accreditation within their facilities. Although the vast majority of laboratories follow current guidelines (83%), only nine laboratories were accredited to ISO/IEC 17025 for hair testing. A significant number of laboratories reporting that they were in the process of developing quality systems with a view to accrediting their methods within 2-3 years. This study provides an insight into the status of accreditation in hair testing laboratories and supports the need for guidelines to encourage best practice.

Recent observations of hydrography, currents and volume transports in the straits of the East/Japan Sea are reviewed. It is newly found that bottom cold water in the Korea/Tsushima Strait originating from the northern region of the East/Japan Sea appears not only in summer and autumn but also in winter. Intensive observations in the Korea/Tsushima Strait revealed two distinct cores of northeastward currents in the upper layer of the western and eastern channels. Mean volume transport through the Korea/Tsushima Strait is calculated as 2.5 ± 0.5 Sv from four-year direct and indirect measurements. As continuous monitoring has started in the Tsugaru and Soya Straits, understanding of temporal variability of currents and volume transports through the straits is in progress. For the first time, simultaneous time series of volume transports are available in the Korea/Tsushima and Tsugaru Straits during the winter of 1999-2000. Ouflow through the Tsugaru Strait accounts for about 70% of inflow through the Korea/Tsushima Strait for this period.

Quantile Regression Models for Current Status Data

Ou, Fang-Shu; Zeng, Donglin; Cai, Jianwen

2016-01-01

Current status data arise frequently in demography, epidemiology, and econometrics where the exact failure time cannot be determined but is only known to have occurred before or after a known observation time. We propose a quantile regression model to analyze current status data, because it does not require distributional assumptions and the coefficients can be interpreted as direct regression effects on the distribution of failure time in the original time scale. Our model assumes that the conditional quantile of failure time is a linear function of covariates. We assume conditional independence between the failure time and observation time. An M-estimator is developed for parameter estimation which is computed using the concave-convex procedure and its confidence intervals are constructed using a subsampling method. Asymptotic properties for the estimator are derived and proven using modern empirical process theory. The small sample performance of the proposed method is demonstrated via simulation studies. Finally, we apply the proposed method to analyze data from the Mayo Clinic Study of Aging. PMID:27994307

The number of foreign workers in Japan, especially temporary workers, has been increasing recently. However, little is known about the mental health status of the foreign workers working temporarily in Japan. We examined the depressive symptoms in 81 Chinese factory workers and attempted to identify the determining factors. The subjects were requested to complete individual questionnaires on sociodemographic variables (sex, age group, and residence period in Japan), working condition variables (number of working days per week and working hours per day), health administration variables (health checkups and health education), a social support variable (interpreters at workplace), and health behavior variables (alcohol consumption, current smoking, and regular exercise). The 20-item Center for Epidemiologic Studies Depression scale (CES-D) was used to measure the depressive symptoms. Of all the subjects, 95% and 84% received health checkups and health education, respectively, at their workplaces. The results of multiple linear regression analysis showed that long working hours per day were significantly associated with high CES-D score. Further, we found that older age (30-49 yr) was marginally associated with high CES-D score. Health administration considering working time and age would be important for decreasing depressive symptoms among foreign workers.

Acupuncture originated in China and is widespread throughout Asia. It is expected that a higher utilization of this remedy exists in these countries compared to Western countries. We conducted annual nationwide surveys from 2003 through 2006 on the utilization of acupuncture in Japan. Face-to-face interviews were conducted with 2000 individuals randomly chosen from the resident database. Annual utilization percentages, based on the number of respondents, from 2003 to 2006 were 6.5%, 4.8%, 6.4%, and 6.7%, respectively, while lifetime experiences determined in each surveys were estimated as 26.7, 19.4, 24.4 and 25.4, respectively. Respondents who had utilized acupuncture and/or moxibustion tended to be older than those who had no experience. Acupuncture was mainly used for musculoskeletal symptoms, and a detailed breakdown of the musculoskeletal symptoms identified in the 2005 survey showed 50.9% for low back pain, 35.9% for shoulder stiffness and 12.0% for knee pain. Reasons given for continuing therapy included the effective amelioration of symptoms, comfort of the procedure and low number of side-effects, while those who decided against continuing cited no improvement of symptoms, cost and lack of time for treatment. In conclusion, annual utilization of acupuncture and/or moxibustion was estimated at more than 6%, and the percentage of those with a lifetime experience was ∼25%, thus demonstrating the relatively higher utilization of the remedy in Japan over utilization in western countries. Application of the treatment for musculoskeletal problems and utilization by the older population were specific standouts of the use of acupuncture and/or moxibustion in Japan.

Data on isolated coronary artery bypass grafting (CABG) performed in 2013 and 2014, and registered in the Japan Cardiovascular Surgery Database were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery (LAD). Isolated CABG was performed off-pump in 54.7% of cases, and graft material for the LAD was left internal thoracic artery in 74.3% and right internal thoracic artery in 15.6%. Operative mortality was 2.0% in elective cases, 8.2% in emergency cases, and 3.0% overall. In elective cases, operative mortality was 1.1% for off-pump CABG compared with 3.0% for on-pump CABG. Clinical results of our isolated CABG were reasonable and acceptable.

Coastal set-net fisheries have been frequently damaged by the occurrence of sudden current (known as kyucho) in the Japan Sea. In this study, a high-resolution coastal ocean model is developed to provide a means to predict this stormy current. The 1.5 km-mesh model nested in a regional ocean data assimilation system is driven by mesoscale atmospheric conditions at 1-hour intervals. The modeled results show rapid changes of the coastal current along the San-in Coast, on the eastern side of the Tango Peninsula, and around the Noto Peninsula and Sado Island, mostly associated with strong wind events. These modeled coastal water responses are consistent with in-situ velocity measurements. The simulation also shows that the vortex separated from the Tango Peninsula frequently grows to a bay-scale anticyclonic eddy in Wakasa Bay. Evidently, the coastal branch of the Tsushima Warm Current becomes unstable due to a strong meteorological disturbance resulting in the generation of this harmful eddy.

A subsequent research program of the EAST-I, an acronym of ″the East Asian Seas Time-series″, was launched by PICES (North Pacific Marine Science Organization) and financially supported by the Korean government, allowing us to deepen our knowledge about rapidly changing processes in the East Sea (Chang et al., 2010). Although there has been considerable progress in developing a mechanistic understanding of the East Sea ecosystem responses to disturbances, more comprehensive studies are needed to address the impacts of the frequency and intensity of disturbances on marine ecosystems. The most important question of the research has been: how do environmental changes affect structural and functional biodiversity? Recently launched research on ″Long-term change of structure and function in marine ecosystems of Korea″, which has been supported by the Korean government since 2011, has given an unprecedented insight into the ecosystem dynamics in the East Sea. It therefore seems an appropriate time to devote a special issue to the topic of ″Current status of the East Sea ecosystem in a changing world″.

A numerical model was established to reproduce the oceanic transport processes of microplastics and mesoplastics in the Sea of Japan. A particle tracking model, where surface ocean currents were given by a combination of a reanalysis ocean current product and Stokes drift computed separately by a wave model, simulated particle movement. The model results corresponded with the field survey. Modeled results indicated the micro- and mesoplastics are moved northeastward by the Tsushima Current. Subsequently, Stokes drift selectively moves mesoplastics during winter toward the Japanese coast, resulting in increased contributions of mesoplastics south of 39°N. Additionally, Stokes drift also transports micro- and mesoplastics out to the sea area south of the subpolar front where the northeastward Tsushima Current carries them into the open ocean via the Tsugaru and Soya straits. Average transit time of modeled particles in the Sea of Japan is drastically reduced when including Stokes drift in the model. Copyright © 2017 The Authors. Published by Elsevier Ltd..

The aim of the present study was to identify factors associated with sarcopenia in community-dwelling elderly women in Japan. A total of 186 women aged over 65 years attending preventive care classes were enrolled in the study. Muscle mass was assessed using bioelectrical impedance analysis. Sarcopenia was defined as low muscle mass and low muscle strength in accord with the consensus report of the Asian Working Group for Sarcopenia. Data regarding household status (living alone, with a spouse, or with children and/or grandchildren), calf circumference and the presence of locomotive syndrome were obtained, as well as dietary variety score, Tokyo Metropolitan Institute of Gerontology Index of Competence and Mini-Nutritional Assessment short form, and 10-item Eating Assessment Tool scores. Sarcopenia was identified in 21.0% of participants. Participants with sarcopenia were older, had a lower body mass index and calf circumference, and were more likely to have locomotive syndrome, and living with children and/or grandchildren. In multivariate analysis, age, body mass index <18.5 and locomotive syndrome were significantly associated with sarcopenia, as were associated living alone (OR 1.69, 95% CI 0.45-6.41), and living with children and/or grandchildren (OR 2.46, 95% CI 0.71-8.54) and dietary variety score ≥9 (OR 4.98, 95% CI 0.97-25.56). Age, body mass index, dietary variety score, locomotive syndrome and household status were associated with sarcopenia. Early interventions are required for older adults identified as having a higher risk of sarcopenia to prevent its adverse health consequences.

Despite great strides in pharmacotherapy for diabetes, there is increasing concern over the risk of hypoglycemia in patients with diabetes receiving pharmacotherapy as they become increasingly older. This has prompted the Japan Diabetes Society (JDS) to initiate a survey on the current status of severe hypoglycemia in clinical settings. In July 2015, following approval from the JDS Scientific Survey/Research Ethics Committee, the JDS extended an invitation to executive educators, who represented a total of 631 healthcare facilities accredited by the JDS for diabetes education, to participate in the proposed survey. Of these, those who expressed their willingness to participate in the survey were sent an application form required for obtaining ethical approval at these healthcare facilities and were then asked, following approval, to enter relevant clinical data on an unlinked, anonymous basis in a web-based registry. The current survey was fully funded by the JDS Scientific Survey/Research Committee. A case registry (clinical case database) was launched after facility-specific information (healthcare facility database) was collected from all participating facilities and after informed consent was obtained from all participating patients. With severe hypoglycemia defined as the "presence of hypoglycemic symptoms requiring assistance from another person to treat and preferably venous plasma glucose levels at onset/diagnosis of disease or at presentation clearly less than 60 mg/dL (capillary whole blood glucose, less than 50 mg/dL)", the current survey was conducted between April 1, 2014 and March 31, 2015, during which facility-specific information was collected from a total of 193 facilities with a total of 798 case reports collected from 113 facilities. Of the 193 respondent facilities, 149 reported having an emergency department as well, with the median number of patients who required emergency transportation services to reach these facilities totaling 4

Japan has no national vaccine registry and approximately 1700 municipalities manage the immunization records independently. In June 2013, proactive recommendations for the human papillomavirus (HPV) vaccine were suspended after unconfirmed reports of adverse events following immunization in the media, despite no vaccine safety signal having been raised. Furthermore, studies assessing HPV vaccine safety and effectiveness published post suspension are predominantly based on self-reported information. Our aim was to examine the accuracy of self-reported vaccination status compared with official municipal records. Participants were women aged 20-22 yrs, who were attending for cervical screening in Niigata city. Among the 1230 eligible registrants, vaccine uptake, defined as any dose, was 75.0% and 77.2% according to a self-reported questionnaire and municipal records, respectively. The accuracy rate of self-reported information was as follows: positive predictive value (PPV) was 87.7%; negative predictive value (NPV) was 54.5%; sensitivity was 85.2%; and specificity was 59.8%. The validity of self-reported information was only moderate (Kappa statistic = 0.44, 95% confidence interval 0.37-0.50). This combined with the low NPV may lead to reduced estimation of effectiveness and safety. A more reliable method, such as a national HPV vaccine registry, needs to be established for assessing HPV immunization status in Japan. Copyright © 2018. Published by Elsevier B.V.

Cognitive function may be influenced by education, socioeconomic status, sex, and health status. Furthermore, aging interacts with these factors to influence cognition and dementia risk in late life. Factors that may increase or decrease successful cognitive aging are of critical importance, particularly if they are modifiable. The purpose of this study was to determine if economic status in late life is associated with cognition independent of socioeconomic status in early life. Cross-sectional demographic, socioeconomic, and cognitive function data were obtained in 2592 older adults (average age 71.6 years) from the Center for Disease Control's National Health and Nutrition Examination Survey (NHANES) and analyzed with linear regression modeling. Cognitive function, as measured with a test of processing speed, was significantly associated with poverty index scores after adjusting for educational attainment as an estimate of childhood socioeconomic status, ethnic background, age, health status, and sex (P < 0.001). Our findings suggest that current economic status is independently associated with cognitive function in adults over age 60 years.

Urologic cancer in Japan: role of Japan at the frontier of issues in Asia.

PubMed

Akaza, Hideyuki

2016-01-01

The characteristics of urological cancer in Japan can be summarized in the following points. (i) As the onset of this type of cancer is typically seen in elderly patients, it is becoming a major social issue in Japan that has already become an aging society. (ii) Many diverse treatment methods are available and a response is required that prioritizes quality of life. (iii) Although vigorous research and development efforts into new drugs are being carried out on a global level, resulting in beneficial medical agents becoming more readily available, unless concepts relating to cost vs. effectiveness are further developed and there is a real risk that medical systems and structures in their current form will become unsustainable. (iv) Although at the current point there are no original large-scale clinical trials being conducted in Asia, Japan has a wealth of experience of participating in many international joint clinical trials and it is therefore an urgent and pressing challenge to organize joint clinical trials in Asia and amass a body of knowledge that is unique to Asia. In view of this current situation and given Japan's position at the frontier of issues, it is important for Japan to take the initiative in Asia in cooperating with other Asian nations in efforts to resolve and overcome various challenges. © The Author 2015.

Documentation of the current status of specialty training to become a neurologist in Japan would represent an important basis for constructing better neurology training program in the planned reform of the specialty training system in Japan. The committee for future neurology specialty system of Japanese Society of Neurology (JSN) conducted a questionnaire survey on the process of specialty training of each trainee for neurology in board-certified educational facilities and semi-educational facilities throughout Japan. The response rate was 46.2% in all facilities and 87.5% in medical universities. The training process of 905 trainees over 5 grades was clarified, which was estimated to be about 80% of all the relevant subjects. Specialty training dedicated to neurology was started at the 3rd year of residency in 87.8% of subjects. During the 3 years following junior residency, 51.3% of subjects ran the rotation training between university and city hospital, whereas 36.5% was trained within the same institution throughout the 3 years of training period.

Acute myeloid leukemia (AML) accounts for 25% of pediatric leukemia and affects approximately 180 patients annually in Japan. The treatment outcome for pediatric AML has improved through advances in chemotherapy, hematopoietic stem cell transplantation (HSCT), supportive care, and optimal risk stratification. Currently, clinical pediatric AML studies are conducted separately according to the AML subtypes: de novo AML, acute promyelocytic leukemia (APL), and myeloid leukemia with Down syndrome (ML-DS). Children with de novo AML are treated mainly with anthracyclines and cytarabine, in some cases with HSCT, and the overall survival (OS) rate now approaches 70%. Children with APL are treated with an all-trans retinoic acid (ATRA)-combined regimen with an 80-90% OS. Children with ML-DS are treated with a less intensive regimen compared with non-DS patients, and the OS is approximately 80%. HSCT in first remission is restricted to children with high-risk de novo AML only. To further improve outcomes, it will be necessary to combine more accurate risk stratification strategies using molecular genetic analysis with assessment of minimum residual disease, and the introduction of new drugs in international collaborative clinical trials. © 2015 Japan Pediatric Society.

The JTEC Panel on Advanced Composites visited Japan and surveyed the status and future directions of Japanese high performance ceramic and carbon fibers and their composites in metal, intermetallic, ceramic and carbon matrices. The panel's interests included not only what composite systems were chosen, but also how these systems were developed. A strong carbon and fiber industry makes Japan the leader in carbon fiber technology. Japan has initiated an oxidation resistant carbon/carbon composite program. The goals for this program are ambitious, and it is just starting, but its progress should be closely monitored in the United States.

The Concealed Information Test (CIT) is a psychophysiological technique for examining whether a person has knowledge of crime-relevant information. Many laboratory studies have shown that the CIT has good scientific validity. However, the CIT has seldom been used for actual criminal investigations. One successful exception is its use by the Japanese police. In Japan, the CIT has been widely used for criminal investigations, although its probative force in court is not strong. In this paper, we first review the current use of the field CIT in Japan. Then, we discuss two possible approaches to increase its probative force: sophisticated statistical judgment methods and combining new psychophysiological measures with classic autonomic measures. On the basis of these considerations, we propose several suggestions for future practice and research involving the field CIT.

The present study reports the current status of computerizing medical records in Japan. In 2001, the Ministry of Health, Labour and Welfare formulated the Grand Design for the Development of Information Systems in the Healthcare and Medical Fields. The Grand Design stated a numerical target for "spreading the use of electronic medical records (EMR) in at least 60% of Japan's hospitals with 400 or more beds by 2006." The objective of this study was to examine the extent to which EMR and order entry systems (OES) have been adopted as of February 2007 and to evaluate the Japanese government's policy regarding the computerization of medical records. We conducted a postal survey targeting medical institutions throughout Japan. In February 2007, we mailed self-administered questionnaires to all 1574 hospitals with 300 or more beds, and to a random selection of 1000 hospitals with less than 300 beds in addition to 4000 clinics. Responses were received from 812 (51.6%), 504 (50.5%), and 1769 (44.8%), respectively. We asked questions concerning: (i) the extent to which EMR and OES had been introduced; (ii) the reasons why certain institutions had not introduced EMR and (iii) the subjective evaluation of the efficacy and cost-effectiveness of EMR. The percentage of institutions that had introduced EMR as of February 2007 was 10.0% for hospitals and 10.1% for clinics. Even the percentage for hospitals with 400 or more beds was just 31.2%, illustrating that the government's target had not been reached. The most common reason given for not introducing EMR was: "The cost is high" which was observed in 82.0% of hospitals. It was considered that the introduction of EMR could improve 'inter-hospital networks', and 'time efficiency for physicians' by around 45% and 25% of hospitals, respectively. Healthcare information computerization in Japan is behind schedule because the introductory costs are high. For the computerization of healthcare information to be further promoted, prices

The association between low socioeconomic status (SES) and dementia is reportedly mediated by lifestyle-related diseases (i.e., diabetes) in European countries and the United States; however, in Japan, the link between low SES and dementia has not been investigated. This study evaluated the possibility of a mediating role of lifestyle-related diseases in the relationship between low SES and dementia in Japan. A retrospective case-control study design, with data from the Toyama Dementia Survey, Japan, was used. Individuals aged ≥65 years (institutionalized and noninstitutionalized) living in Toyama prefecture were randomly selected, with a sampling rate of 0.5%. Of them, 1303 agreed to participate (response rate 84.8%). Overall, 137 cases of dementia and 1039 unimpaired controls were identified. Structured interviews with participants and family members or proxies were conducted, if necessary. Participants' history of medically diagnosed disease, lifestyle factors (i.e., smoking and alcohol drinking habits), and SES (educational attainment and occupational history) were assessed. The possibility of low SES being a risk factor for dementia via lifestyle-related diseases was investigated using the Sobel test. The odds ratio (OR) for dementia was higher for participants with low educational attainment (6 years or less) than for highly educated participants [age- and sex-adjusted OR 3.27; 95% confidence interval (CI) 1.84-5.81]; it was also higher for participants with a blue-collar job history than a white-collar job history (age- and sex-adjusted OR 1.26; 95% CI 0.80-1.98). After adjustment for employment history, the OR for dementia for participants with low educational attainment was 3.23-3.56. Former habitual alcohol consumption and a medical history of diabetes, Parkinson's disease, stroke, and angina pectoris/cardiovascular disease were found to increase the risk of dementia. Educational attainment was not associated with alcohol consumption, smoking

Although bilateral lung transplantation is the procedure of choice internationally, single lung transplantation is preferred in Japan because of the severe donor shortage except in cases of contraindications to single lung transplantation. This study aimed to evaluate the clinical characteristics of single lung transplant recipients and outcomes of this procedure at one of the largest lung transplant centers in Japan. Between April 2002 and May 2015, 57 cadaveric lung transplantations (33 single and 24 bilateral) were performed in Kyoto University Hospital. The clinical characteristics of the lung transplant recipients and outcomes of these procedures, including overall survival and postoperative complications, were investigated. Overall, the 1-, 3-, and 5-year survival rates were 86, 77, and 72 %, respectively, with a median follow-up period of 1.9 years. There was no significant difference in survival between patients who underwent single lung transplantations and those who underwent bilateral lung transplantations (p = 0.92). The median waiting time was significantly shorter for single lung transplant patients than for bilateral lung transplant patients (p = 0.02). Native lung complications were seen in 14 out of 33 patients (42 %) who underwent single lung transplantation. There was no significant difference in survival between patients with and without postoperative native lung complications. Single lung transplantation has been performed with acceptable outcomes in our institution. In the current situation of severe donor shortage in Japan, single lung transplantation can remain the first choice of treatment except in cases of contraindications to single lung transplantation.

The potentials of bubble technology in ultrasound has been investigated thoroughly in the last decade. Japan has entered as one of the leaders in bubble technology in ultrasound since Sonazoid (Daiichi Sankyo & GE Healthcare) was marketed in 2007. The 85th Annual Scientific Meeting of The Japan Society of Ultrasonics in Medicine held in Tokyo from May 25 to 27, 2012 is where researchers and clinicians from all over Japan presented recent advances and new developments in ultrasound in both the medical and the engineering aspects of this science. Even though bubble technology was originally developed simply to improve the conventional ultrasound imaging, recent discoveries have opened up powerful emerging applications. Bubble technology is the particular topic to be reviewed in this report, including its mechanical advances for molecular imaging, drug/gene delivery device and sonoporation up to its current clinical application for liver cancers and other liver, gastrointestinal, kidney and breast diseases.

The amino acid l-citrulline is used as a therapeutic agent for urea cycle disorders (UCD) including ornithine transcarbamylase deficiency (OTCD), carbamoyl phosphate synthetase I deficiency (CPSD), and N-acetylglutamate synthase deficiency. There are few reports, however, on the use of l-citrulline in Japan and little consensus regarding the effects of l-citrulline. We conducted a questionnaire survey of patients undergoing l-citrulline treatment for a UCD to evaluate the current status of this therapy. The survey included patient background, details of l-citrulline treatment, clinical examination data, treatment, frequency of vomiting, and liver transplantation. We retrospectively investigated 43 questionnaire respondents (OTCD, n = 33; CPSD, n = 10). The weight of male OTCD patients improved by +0.79 SD, and the ammonia level decreased by a mean of 44.3 μmol/L in all patients. The protein intake of all patients and of male OTCD patients increased by 0.14 g/kg/day and 0.17 g/kg/day, respectively. l-Citrulline effectively reduced ammonia level, increased protein intake, and improved weight gain in UCD patients. l-Citrulline should be considered a standard therapy in OTCD and CPSD patients. © 2016 Japan Pediatric Society.

Recently, researchers have proposed that psychological resources might be key concept in explaining the association between social class and health. However, empirical examinations of the extent to which psychological resources to social class in health are still few. This study investigated mediating effects of selected psychological resources (sense of control, self-esteem, optimism, and neuroticism) on the association of social class [education and subjective social status (SSS)] with current health status (self-rated health and the number of chronic conditions). This sample consisted of 1,805 Americans (818 males and 987 females) from the Midlife in the United States (MIDUS) survey, 2004-2006 and 1,027 Japanese (505 males and 522 females) from the Midlife in Japan (MIDJA) survey in Tokyo, Japan, 2008-2010. Information on social class, psychological resources, and health status was obtained using telephone interviews or written questionnaires. A mediation analysis was conducted separately for males and females in Japan and the USA. Neuroticism significantly mediated the association of education and SSS with self-rated health and chronic conditions among males and females in both countries, with one exception (not for chronic conditions among Japanese females). Sense of control significantly mediated the association of education and SSS with self-rated health among males and females in both countries. As hypothesized, self-esteem significantly mediated almost all of the associations of education and SSS with self-rated health and chronic conditions among men and women in the USA, but very few such associations in Japan. Optimism significantly mediated most associations of social class and health status in both countries, but only among females. Overall, the findings underscore important culture- and gender specificity in the ways in which psychosocial resources mediate the links between social class and health.

Because of a strong carbon and fiber industry, Japan is the leader in carbon fiber technology. Japan has initiated an oxidation-resistant carbon/carbon composite program. With its outstanding technical base in carbon technology, Japan should be able to match present technology in the U.S. and introduce lower-cost manufacturing methods. However, the panel did not see any innovative approaches to oxidation protection. Ceramic and especially intermetallic matrix composites were not yet receiving much attention at the time of the panel's visit. There was a high level of monolithic ceramic research and development activity. High temperature monolithic intermetallic research was just starting, but notable products in titanium aluminides had already appeared. Matrixless ceramic composites was one novel approach noted. Technologies for high temperature composites fabrication existed, but large numbers of panels or parts had not been produced. The Japanese have selected aerospace as an important future industry. Because materials are an enabling technology for a strong aerospace industry, Japan initiated an ambitious long-term program to develop high temperature composites. Although just starting, its progress should be closely monitored in the U.S.

Recent studies from the USA and Europe suggest an association between an individual's political ideology and their health status, with those claiming to be conservatives reporting better health. The presence of this association is examined in Japan. Individual-level data from the 2000-3, 2005 and 2006 Japan General Social Survey were analysed. The outcomes of interest were self-rated poor health and smoking status. The independent variable of interest was reported political beliefs on a 5-point 'left'-to-'right' scale. Covariates included age, sex, education, income, occupational status and fixed effects for survey periods. Logistic regression models were estimated. There was an inverse association between political ideology (left to right) and self-rated poor health as well as between ideology and smoking status even after adjusting for age, sex, socioeconomic status and fixed effects for survey periods. Compared with those who identified as 'left', the OR for reporting poor health and smoking among those who identified as 'right' was 0.86 (95% CI 0.74 to 0.99) and 0.80 (95% CI 0.70 to 0.91), respectively. Health differences by political ideology have typically been interpreted as reflecting socioeconomic differences. The results from Japan corroborate the previous findings from the USA and Europe that socioeconomic differences do not account for health differences by political ideologies. Political ideology is likely to be a marker of several latent values and attitudes (eg, religiosity, individual responsibility and/or community participation) that might be beneficial for health at the individual level.

In Japan, as the number of elderly covered by the Long-term Care Insurance (LTCI) system has increased, demand for long-term care services has increased substantially and consequently growing expenditures are threatening the sustainability of the system. Understanding the predictive factors associated with long-term care expenditures among the elderly would be useful in developing future strategies to ensure the sustainability of the system. We report a set of predictors of the highest long-term care expenditures in a cohort of elderly persons who received consecutive long-term care services during a year in a Japanese city. Data were obtained from databases of the LTC insurer of City A in Japan. Binary logistic regression was used to examine the predictors of the highest long-term care expenditures. We used a simplified model that focused on the effects of disability status and type of services used, while controlling for several relevant factors. Goodness of fit, a multicollinearity test, and logistic regression diagnostics were carried out for the final model. The study cohort consisted of 862 current users of LTCI system in city A. After controlling for gender and income, age, increased utilization rate of benefits, decline in functional status, higher care needs level and institutional care were found to be associated with the highest LTCI expenditures. An increased utilization rate of benefits (OR = 24.2) was a strong main effect predictors of the high LTC expenditures. However, a significant interaction between institutional care and high care need level was found, providing evidence of the combined effect of the two covariates. Beyond to confirm that disability status of elderly persons is the main factor driving the demand of LTC services and consequently the expenditures, we showed that changes in utilization rate of benefits -a specific insurance factor- and the use of institutional care conditional on the high care level, were strongest predictors of

This paper discusses regression analysis of current status failure time data arising from the additive hazards model in the presence of informative censoring. Many methods have been developed for regression analysis of current status data under various regression models if the censoring is noninformative, and also there exists a large literature on parametric analysis of informative current status data in the context of tumorgenicity experiments. In this paper, a semiparametric maximum likelihood estimation procedure is presented and in the method, the copula model is employed to describe the relationship between the failure time of interest and the censoring time. Furthermore, I-splines are used to approximate the nonparametric functions involved and the asymptotic consistency and normality of the proposed estimators are established. A simulation study is conducted and indicates that the proposed approach works well for practical situations. An illustrative example is also provided.

ABSTRACT Little is known about the current health status of US metal and nonmetal (MNM) miners, in part because no health surveillance systems exist for this population. The National Institute for Occupational Safety and Health (NIOSH) is developing a program to characterize burden of disease among MNM miners. This report discusses current knowledge and potential data sources of MNM miner health. Recent national surveys were analyzed, and literature specific to MNM miner health status was reviewed. No robust estimates of disease prevalence were identified, and national surveys did not provide information specific to MNM miners. Because substantial gaps exist in the understanding of MNM miners' current health status, NIOSH plans to develop a health surveillance program for this population to guide intervention efforts to reduce occupational and personal risks for chronic illness.

This report summarizes the status of electronic manufacturing and packaging technology in Japan in comparison to that in the United States, and its impact on competition in electronic manufacturing in general. In addition to electronic manufacturing technologies, the report covers technology and manufacturing infrastructure, electronics manufacturing and assembly, quality assurance and reliability in the Japanese electronics industry, and successful product realization strategies. The panel found that Japan leads the United States in almost every electronics packaging technology. Japan clearly has achieved a strategic advantage in electronics production and process technologies. Panel members believe that Japanese competitors could be leading U.S. firms by as much as a decade in some electronics process technologies. Japan has established this marked competitive advantage in electronics as a consequence of developing low-cost, high-volume consumer products. Japan's infrastructure, and the remarkable cohesiveness of vision and purpose in government and industry, are key factors in the success of Japan's electronics industry. Although Japan will continue to dominate consumer electronics in the foreseeable future, opportunities exist for the United States and other industrial countries to capture an increasingly large part of the market. The JTEC panel has identified no insurmountable barriers that would prevent the United States from regaining a significant share of the consumer electronics market; in fact, there is ample evidence that the United States needs to aggressively pursue high-volume, low-cost electronic assembly, because it is a critical path leading to high-performance electronic systems.

Health Technology Assessment (HTA) is the systematic evaluation to measure the value of new health technologies. It improves the quality of choices on hand for cost-effective health technologies that are considered valuable. Japan has built a society of longevity consisted of the institution of the universal health care system, which is financially unsustainable. In Japan, no independent HTA organization has been publicly established but the government is contemplating implementation of such system. To advance the usage of HTA into surgery, we need to establish methods for evaluating new surgical technologies with steep learning curves. The promotion of clinical researches is also essential, especially by taking advantage of observational studies from medical big data such as the Japanese nationwide database which has more than four million surgical cases registered. In addition, we need more clinical information regarding each surgical patient's quality of life and socioeconomic status. The countries already introduced HTA into their health care system have measures to solve the problems that arose and have developed necessary evaluating methods. To introduce and promote HTA in Japan without taking away the benefit of our current healthcare, it is required that surgeons collaborate with other specialists such as methodologists and health economists.

Iatrogenic and spontaneous downstream microembolization of atheromatous material is increasingly recognized as a source of cardiovascular morbidity and mortality. Devising ways of reducing this distal embolization using a variety of mechanical means--distal protection--is currently under intense and diverse investigation. This review therefore summarizes the present status of distal protection. It examines the problem of distal embolization, describes the available distal protection devices, reviews those areas of cardiovascular medicine where distal protection devices are being investigated, and discusses potential future developments.

Controls for second hand smoke (SHS) and adolescent smoking have been still sociomedical concerns in Japan. Restaurant smoking restrictions are associated with community social norms affecting adolescent smoking behavior, and the status in areas around Junior high schools (JHSs) in the community could be a sign of community practices on regulating SHS for adolescents. To examine whether restaurant smoking restrictions are seen especially in areas around JHSs in Japan, a survey using the direct inspection of a total of 163 restaurants (64 restaurants within and 99 outside a 1-km radius from the nearest JHSs) was conducted in May 2003 in Yonago city, Japan. We assessed smoking restriction status in each restaurant and classified them into 2 groups according to the distance from the nearest JHSs. There were only 2 (3.1%) restaurants with 100% non-smoking and 11 (17.2%) with some partial restrictions among the restaurants within a 1-km radius of JHSs. There were 1 (1.0%) restaurant with 100% non-smoking, 3 (3.0%) with complete non-smoking sections and 17 (17.2%) with some partial restrictions among the restaurants outside a 1-km radius of JHSs. Among restaurants with some partial restrictions, restriction methods were considered insufficient. The smoking restriction status was not significantly different between the restaurant groups within and outside a 1-km radius of JHSs. These results suggest that the public awareness of and attitude toward adolescent smoking problems remains low in Japan. Further SHS control actions for adolescents are needed in Japan.

Spontaneous reports on suspected serious adverse events caused by medicines from manufacturing/distributing pharmaceutical companies or medical institutions/pharmacies are regulated by the Pharmaceutical Affairs Law of Japan, and this system is important for post-marketing safety features. Although causal relationship between the medicine and the adverse event is not evaluated, and one incidence may be redundantly reported, this information would be useful to roughly grasp the current movements of drug-related serious adverse events, We searched open-source data of the spontaneous reports publicized by Pharmaceutical and Medical Devices Agency for 4 serious adverse events (interstitial lung disease, rhabdomyolysis, anaphylaxis, and Stevens-Johnson syndrome/toxic epidermal necrolysis) from 2004 to 2010 fiscal year (for 2010, from April 1 st to January 31th). Major drug-classes suspected to the adverse events were antineoplastics for interstitial lung disease, hyperlipidemia agents and psychotropics for rhabdomyolysis, antibiotics/chemotherapeutics, antineoplastics and intracorporeal diagnostic agents for anaphylaxis (anaphylactic shock, anaphylactic reactions, anaphylactoid shock and anaphylactoid reactions), and antibiotics/chemotherapeutics, antipyretics and analgesics, anti-inflammatory agents/common cold drugs, and antiepileptics for Stevens-Johnson syndrome/toxic epidermal necrolysis. These results would help understanding of current situations of the 4 drug-related serious adverse events in Japan.

As the number of donated organs is still extremely small in Japan compared with other developed countries, in-hospital procurement transplant coordinators (In-Hp PTC) may play an important role in increasing organ donation and making the procurement procedure smoother. In this study, our education program of In-Hp PTC is described. In May 2012, our department started the In-Hp PTC Education Program. In the first semester, a 2-hour lecture is provided every 2 weeks for 5 months to 15 In-Hp PTCs working near Osaka. In the second semester, 20 lectures were provided for 3 consecutive days to 31 In Hp PTCs, more than 80% of whom work far from Osaka. Lecture topics were the history and current status of organ donation in Japan, social regulation of organ donation, care of transplant recipients, overall procedures of organ donation, the role of In-Hp PTC, donor family care, donor indications, and donor assessment and management. Lectures also included simulations of the organ donation process. Participants were surveyed for their opinions after the program, Most participants were satisfied with the program, topics and duration. As most of them are not full-time In-Hp PTCs, they preferred to attend the 3-day program. Many participants are currently working as main In-Hp PTCs and establishing their own organ donation system in their hospital. In-Hp PTCs have an important role to play in establishing an organ procurement system and increasing organ donation in Japan. This program may help establish a systematic education program for this occupation in Japan. Copyright © 2014 Elsevier Inc. All rights reserved.

Objective The present study examined nutritional status and dietary intake of pregnant women in Japan in relation to pre-pregnancy body mass index (BMI).Methods Participants included 141 Japanese women with singleton pregnancies, from the outpatient department of the S hospital, Gunma prefecture, Japan. Two-day food records, dietary assessment questionnaires, and clinical records were obtained at 20 weeks gestation. Nine patients were excluded from the study due to morning sickness. The remaining 132 participants were divided into 3 groups according to pre-pregnancy BMI: underweight, normal weight, and overweight. Nutritional status and dietary intake were analyzed in relation to BMI using the chi-square test, Fisher's exact test, Kruskal-Wallis test, one-way analysis of variance, and analysis of covariance with adjustment for age, employment status, and total energy intake.Results Women who were underweight before pregnancy were more frequently working full-time than normal weight and overweight women. Underweight women were also more frequently anemic (P=0.038, underweight 39.3%, normal weight 24.7%, overweight 0%) and had lower mean hemoglobin (Hb) (P=0.021, underweight 11.3 g/dL, normal weight 11.6 g/dL, overweight 12.1 g/dL) and hematocrit (Hct) levels (P=0.025, underweight 33.7%, normal weight 34.3%, overweight 36.0%). Their dietary intake of protein, iron, magnesium, and folic acid was lower than that of normal weight and overweight women. Their meals tended to include fewer meat, fish, egg, and soybean dishes (underweight, mean of 4.7 servings per day; normal weight, 6.1 servings; overweight, 6.1 servings).Conclusion Pregnant women who were underweight before pregnancy had increased risk of anemia as well as reduced Hb and Hct levels. They had lower dietary intake of protein, iron and folic acid compared to women in the other BMI categories. Anemia and these nutrient deficiencies are known risk factors for low birth weight.

The International VLBI Service for Geodesy and Astrometry (IVS) is a globally operating service that coordinates and performs Very Long Baseline Interferometry (VLBI) activities through its constituent components. The VLBI activities are associated with the creation, provision, dissemination, and archiving of relevant VLBI data and products. The products mostly pertain to the determination of the celestial and terrestrial reference frames, the Earth orientation parameters (EOP), atmospheric parameters as well as other ancillary parameters. The IVS observational network currently consists of about 40 radio telescopes worldwide. Subsets of these telescopes (8-12 stations) participate in 24-hour observing sessions that are run several times per week and in 1-hour intensive sessions for UT1 determination every day. The current VLBI network was developed mainly in the 1970s and 1980s. A number of factors, including aging infrastructure and demanding new scientific requirements, started to challenge its future sustainability and relevance. In response, the IVS and other groups developed and started implementing the next generation VLBI system, called VGOS (VLBI Global Observing System), at existing and new sites. The VGOS network is expected to reach maturity in the early 2020s. We describe the current status, progress, and anticipated prospects of geodetic/astrometric VLBI and the IVS.

The increase in implant patients is expected to give rise to a new problem: the changing general health status of those who have had implants placed. The aim of this present study was to find out the needs of and proper measures for elderly implant patients in long-term care facilities. A questionnaire was sent by mail to 1,591 long-term care health facilities, daycare services for people with dementia, and private nursing homes for the elderly in the Osaka area, which is in the middle area of Japan, in order to extract patients with cerebrovascular disease or dementia who were possibly at risk of inadequate oral self-care, as well as patients with implants. Approximately half of all facilities responded that they cannot recognize implants, and many facilities did not know anything about oral care for implant patients. Residents with implants were reported at 19% of all facilities. Also, the facilities pointed out problems with implants relating to the difference in oral care between implants and natural teeth. There are people with implants in some 20% of caregiving facilities, and there is a low level of understanding regarding implants and their care among nurses and care providers who are providing daily oral care. © 2013 Wiley Periodicals, Inc.

Like health care systems in other developed countries, Japan's health care system faces significant challenges due to aging of the population and economic stagnation. Advanced medicine (Senshin Iryou) is a unique system of medical care in Japan offering highly technology-driven medical care that is not covered by public health insurance. Advanced medicine has recently developed and expanded as part of health care reform. Will it work? To answer this question, we briefly trace the historical development of advanced medicine and describe the characteristics and current state of advanced medical care in Japan. We then offer our opinions on the future of advanced medicine with careful consideration of its pros and cons. We believe that developing advanced medicine is an attempt to bring health care reform in line rather than the goal of health care reform.

Prostate-specific membrane antigen (PSMA) is a promising target for imaging diagnostics and targeted radionuclide therapy (theranostics) of prostate cancer and its metastases. There is increasing evidence of encouraging response rates and a low toxicity profile of radioligand therapy (RLT) of metastatic castration-resistant prostate cancer using 177Lu-labeled PSMA ligands. In this article, we review the current status of diagnostics and therapy using radiolabeled PSMA ligands. We also suggest protocols for patient selection criteria and conduct of PSMA-based RLT. Challenges and opportunities of PSMA theranostics are discussed. PMID:29873291

Why screening rates vary between Korea and Japan--differences between two national healthcare systems.

Goto, Rei; Hamashima, Chisato; Mun, Sunghyun; Lee, Won-Chul

Both Japan and Korea provide population-based screening programs. However, screening rates are much higher in Korea than in Japan. To clarify the possible factors explaining the differences between these two countries, we analyzed the current status of the cancer screening and background healthcare systems. Population- based cancer screening in Korea is coordinated well with social health insurance under a unified insurer system. In Japan, there are over 3,000 insurers and coordinating a comprehensive strategy for cancer screening promotion has been very difficult. The public healthcare system also has influence over cancer screening. In Korea, public healthcare does not cover a wide range of services. Almost free cancer screening and subsidization for medical cost for cancers detected in population-screening provides high incentive to participation. In Japan, on the other hand, a larger coverage of medical services, low co-payment, and a lenient medical audit enables people to have cancer screening under public health insurance as well as the broad range of cancer screening. The implementation of evidence-based cancer screening programs may be largely dependent on the background healthcare system. It is important to understand the impacts of each healthcare system as a whole and to match the characteristics of a particular health system when designing an efficient cancer screening system.

One hundred and seventy three bone marrow transplantations (BMT) including 133 allogeneic, 17 syngeneic and 23 autologous BMT were recorded in Japan during the period between September, 1975 and March, 1984. The number of cases of BMT increased rapidly over the years, i.e., 16 cases in 1980, 27 in 1981, 39 in 1982 and 57 in 1983. All cases were treated in clean rooms, many of them receiving intensive gut decontamination containing vancomycin. In 110 cases with acute leukemia, the main causes of death were interstitial pneumonitis, relapse of leukemia, infection and GvHD. Favorable factors determined from 180-day survival were remission, no infection, low dose rate and fractionated total body irradiation (TBI), ABO minor mismatch and positive graft versus host reaction. Long-term survival of patients who received BMT during remission and were without infection amounted to 70% of acute lymphocytic leukemia (ALL) and 40% of acute myelogenous leukemia (AML) patients. Cyclosporin A (Cy-A) administered in 21 cases was compared with methotrexate (MTX) given in 20 cases. A statistically significant decrease of stomatitis was observed, while no difference in GvHD or survival was seen. There were seven cases giving a more than good response out of 11 cases treated with cyclosporin because methotrexate or immuran was ineffective or could not be administered due to toxicity. Such data suggest that allogeneic BMT is acceptable as a very promising form of treatment for acute leukemia in Japan.

Although socioeconomic status (SES) may affect food and nutrient intakes, few studies have reported on sodium (Na) and potassium (K) intakes among individuals with various SESs in Japan. We investigated associations of SES with Na and K intake levels using urinary specimens in a representative Japanese population. This was a cross-sectional study of 2,560 men and women (the NIPPON DATA2010 cohort) who participated in the National Health and Nutrition Survey Japan in 2010. Casual urine was used to calculate estimated excretion in 24-hour urinary Na (E24hr-Na) and K (E24hr-K). The urinary sodium-to-potassium (Na/K) ratio was calculated from casual urinary electrolyte values. An analysis of covariance was performed to investigate associations of aspects of SES, including equivalent household expenditure (EHE), educational attainment, and job category, with E24hr-Na, E24hr-K, and the Na/K ratio for men and women separately. A stratified analysis was performed on educational attainment and the job category for younger (<65 years) and older (≥65 years) participants. In men and women, average E24hr-Na was 176.2 mmol/day and 172.3, average E24hr-K was 42.5 and 41.3, and the average Na/K ratio was 3.61 and 3.68, respectively. Lower EHE was associated with a higher Na/K ratio in women and lower E24hr-K in men and women. A shorter education was associated with a higher Na/K ratio in women and younger men, and lower E24hr-K in older men and women. Lower EHE and a shorter education were associated with a lower K intake and higher Na/K ratio estimated from casual urine specimens in Japanese men and women.

The Japan Diabetes Society (JDS) has recommended target levels of glycemic control based on guidelines for the management of diabetes mellitus (DM). The Japan Society of Ningen Dock created a database of subjects receiving annual health examinations nationwide. Using this database, we evaluated the efficacy of current treatment for patients with DM based on the JDS recommendations. This multicenter, retrospective study was conducted using data obtained from 21 institutions across Japan. In order to assess the level of glycemic control in the Japanese population, we analyzed previously obtained measurements of HbA1c in 7,180 patients 20 to 79 years of age (mean age: 57.9 ± 8.7 years, 6,007 men and 1,173 women) taking DM medications. According to the JDS guidelines, 44.7% of the patients fell into the good glycemic control group, with an HbA1c level of <7.0% while 22.4% were classified into the poor glycemic control group, with an HbA1c level of ≥ 8.0%. The control of other arteriosclerosis risk factors deteriorated as the glycemic control deteriorated. Lifestyle factors were strongly found to be associated with glycemic control in the patients receiving DM treatment. Aggressive lifestyle modification is needed to improve glycemic control in patients with DM.

Laparoscopic total gastrectomy (LTG) has been widely performed for gastric cancer in China, Korea, and Japan. The current status of this surgical approach needs to be investigated. During the 11th China-Korea-Japan Laparoscopic Gastrectomy Joint Seminar in Shanghai, China, on 5 March 2016, a questionnaire was completed by 65 experts in LTG. The survey included questions on surgical indication, operation team, laparoscopic instruments, and operative procedures. Of the 65 respondents, 35 (53.8%) were from China, 18 (27.7%) were from Korea, and 12 (18.5%) were from Japan. Surgeons have various indications for LTG. Among respondents, stage II gastric cancer (42.9%) was the most acceptable indication, but Japanese surgeons were more cautious on this issue (P = 0.005). Using a flexible scope was more popular with Japanese surgeons than with others (P = 0.003). A goose-neck curved grasper was used more often in China and Korea than in Japan (P = 0.006). Chinese surgeons preferred vertical subxiphoid mini-laparotomy rather than vertical transumbilical laparotomy. Intracorporeal reconstruction (73.0%) was most frequently adopted for LTG. Linear staplers (53.8%) and circular staplers (42.1%) were both popular for esophagojejunostomy. However, jejunojejunostomy was more often conducted extracorporeally (67.7%), in which case a linear stapler (86.4%) was usually selected. Significant differences were observed between the three countries with regard to reinforcement of the duodenal stump (P = 0.018) and closure of Peterson's space (P < 0.001). This survey on LTG involving surgeons from China, Korea, and Japan clearly informed the current practice of this surgical approach and will likely aid future research studies as well as clinical treatment for gastric cancer. © 2017 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

The taxonomic placement of the genus is discussed, and the evolution of our approach to species concepts and anamorph-teleomorph relationships is described. The application of multilocus technologies to phylogenetic analysis of Colletotrichum is reviewed, and selection of potential genes/loci for barcoding purposes is discussed. Host specificity and its relation to speciation and taxonomy is briefly addressed. A short review is presented of the current status of classification of the species clusters that are currently without comprehensive multilocus analyses, emphasising the orbiculare and destructivum aggregates. The future for Colletotrichum biology will be reliant on consensus classification and robust identification tools. In support of these goals, a Subcommission on Colletotrichum has been formed under the auspices of the International Commission on Taxonomy of Fungi, which will administer a carefully curated barcode database for sequence-based identification of species within the BioloMICS web environment.

Crase, D

1981-12-01

A national survey was conducted among 205 university level divisions/departments of health education to determine the current status of death education courses within the health education field. Forty-nine college and university health educators currently teaching the course returned usable instruments. Death education receives the same credit, utilizes similar grading systems and is generally managed much like other academic courses. Since the discipline is in its infancy and many teachers are relatively unprepared, respondents called for greater quality control and improved professional preparation. Several concerns accompanying the growth of death education were identified.

This study aimed to ascertain the current status of Japanese sperm banking for young cancer patients. During 2015, we mailed the directors of 695 institutes where sperm cryopreservation might be performed with questionnaires requesting information on the number of patients, age, precryopreservation chemotherapy, semen analyses results and diagnoses, cryopreservation success rate, and causes of unsuccessful cryopreservation. Of these 695 institutes, 92 had cryopreserved sperm before chemotherapy within the study period. In all, 820 cancer patients (237 testicular, 383 hematological, 46 bone and soft tissue, 20 brain, and 134 other malignancy) consulted the responding institutes for sperm cryopreservation. Except for testicular tumor, the number of patients whose sperm was preserved before cancer treatment was low compared to that of young cancer patients. Approximately 20% of patients with malignancies other than testicular tumor underwent chemotherapy before cryopreservation. The success rate of cryopreservation in hematological malignancy was 82.5%, significantly lower than that of both the testicular cancer (93.6%) and other malignancy groups (95.6%) (P < 0.05). The primary reasons for preservation failure were azoospermia and poor semen quality. Patients with hematological malignancies had a higher rate of unsuccessful cryopreservation compared to those in other groups, possibly due to the large number of patients requesting sperm cryopreservation after chemotherapy induction. In Japan, information regarding sperm banking prior to cancer treatment appears to be lacking. Information regarding sperm preservation before chemotherapy should be provided to all Japanese oncologists.

2008-01-01

The history of the Red List of Japanese vascular plants is briefly reviewed for editing and research. Especially on the results of recent monitoring, the present status of information and conservation activities on the endangered plants in Japan is discussed and the dynamics of the Japanese flora are taken up, in relation to basic research on plant biodiversity on the Japanese Archipelago. The figures of endangered plants are not very variable during the past quarter of a century, but we can surmise that the conservation of threatened species in Japan has been promoted to some extent. Based on the results of such a study, proposals are made to contribute to the sustainable use of plant biodiversity on the Japanese Archipelago under a global conspectus. PMID:18941303

Extensive efforts have been made in both academia and industry in the research and development of smart wearable systems (SWS) for health monitoring (HM). Primarily influenced by skyrocketing healthcare costs and supported by recent technological advances in micro- and nanotechnologies, miniaturisation of sensors, and smart fabrics, the continuous advances in SWS will progressively change the landscape of healthcare by allowing individual management and continuous monitoring of a patient's health status. Consisting of various components and devices, ranging from sensors and actuators to multimedia devices, these systems support complex healthcare applications and enable low-cost wearable, non-invasive alternatives for continuous 24-h monitoring of health, activity, mobility, and mental status, both indoors and outdoors. Our objective has been to examine the current research in wearable to serve as references for researchers and provide perspectives for future research. Herein, we review the current research and development of and the challenges facing SWS for HM, focusing on multi-parameter physiological sensor systems and activity and mobility measurement system designs that reliably measure mobility or vital signs and integrate real-time decision support processing for disease prevention, symptom detection, and diagnosis. For this literature review, we have chosen specific selection criteria to include papers in which wearable systems or devices are covered. We describe the state of the art in SWS and provide a survey of recent implementations of wearable health-care systems. We describe current issues, challenges, and prospects of SWS. We conclude by identifying the future challenges facing SWS for HM. Copyright © 2012 Elsevier B.V. All rights reserved.

Current Status and Challenges of Atmospheric Data Assimilation

Atlas, R. M.; Gelaro, R.

2016-12-01

The issues of modern atmospheric data assimilation are fairly simple to comprehend but difficult to address, involving the combination of literally billions of model variables and tens of millions of observations daily. In addition to traditional meteorological variables such as wind, temperature pressure and humidity, model state vectors are being expanded to include explicit representation of precipitation, clouds, aerosols and atmospheric trace gases. At the same time, model resolutions are approaching single-kilometer scales globally and new observation types have error characteristics that are increasingly non-Gaussian. This talk describes the current status and challenges of atmospheric data assimilation, including an overview of current methodologies, the difficulty of estimating error statistics, and progress toward coupled earth system analyses.

A class of semiparametric cure models with current status data.

PubMed

Diao, Guoqing; Yuan, Ao

2018-02-08

Current status data occur in many biomedical studies where we only know whether the event of interest occurs before or after a particular time point. In practice, some subjects may never experience the event of interest, i.e., a certain fraction of the population is cured or is not susceptible to the event of interest. We consider a class of semiparametric transformation cure models for current status data with a survival fraction. This class includes both the proportional hazards and the proportional odds cure models as two special cases. We develop efficient likelihood-based estimation and inference procedures. We show that the maximum likelihood estimators for the regression coefficients are consistent, asymptotically normal, and asymptotically efficient. Simulation studies demonstrate that the proposed methods perform well in finite samples. For illustration, we provide an application of the models to a study on the calcification of the hydrogel intraocular lenses.

Two rotavirus vaccines are currently available in Japan. We estimated the incremental cost-effectiveness ratio (ICER) of routine infant rotavirus immunisation program without defining which vaccine to be evaluated, which reflects the current deliberation at the Health Science Council in charge of Immunisation and Vaccine established by the Ministry of Health, Labor and Welfare of Japan. Three ICERs were estimated, one from payers' perspective and 2 from societal perspective depending on the scenarios to uptake vaccines. The health statuses following the birth cohort were as follows: not infected by rotavirus, asymptomatic infection, outpatients after infection, hospitalised after infection, developing encephalitis/encephalopathy followed by recovery, sequelae, and death. Costs of per course of vaccination was ¥30,000 (US$283; US$1 = ¥106). The model runs for 60 months with one month cycle. From payers' perspective, estimated ICERs were ¥6,877,000 (US$64,877) per QALY. From societal perspective, immunisation program turns out to be cost-saving for 75% simultaneous vaccination scenario, while it is at ¥337,000 (US$3,179) per QALY gained with vaccine alone scenario. The probability of rotavirus immunisation program to be under ¥5,000,000 (US$47,170) per QALY was at 19.8%, 40.7%, and 75.6% when costs per course of vaccination were set at ¥30,000 (US$283), ¥25,000 (US$236), and ¥20,000 (US$189), respectively. Rotavirus immunisation program has a potential to be cost-effective from payers' perspective and even cost-saving from societal perspective in Japan, however, caution should be taken with regard to the interpretation of the results as cost-effectiveness is critically dependent on vaccination costs.

Investigative research on potential market for TPV power sources in Japan has been focused on how TPV can contribute to energy conservation and environmental protection and harmony. The application needs for TPV were surveyed in comparison with conventional engine or turbine generators and developing power generation technologies such as fuel cells or chemical batteries, etc. The investigation on the performance of commercial generators shows that regarding system efficiency, TPV can compete with conventional generators in the output power class of tens of kW. According to the sales for small scale generators in Japan, most of the generators below 10 kW class are utilized mainly for construction, communication, leisure, and that 10-100 kW class generators are for cogeneration in small buildings. Waste heat recovery in dispersed furnaces is another potential application of compact TPV cells. Exhaust heat from small scale incinerators and industrial furnaces is undesirable to be recorded into electricity due to excessive heat loss of the smaller steam turbine generators. Solar powered TPV is also of our concern as a natural energy use. From the viewpoint of applicability for TPV, portable generators cogeneration systems, and solar power plants were selected for our system consideration. Intermediate report on the feasibility study concerning such TPV systems is given as well as the review of the current status of competing power generation technologies in Japan.

Although Japan is a non-endemic area with nasopharyngeal carcinoma (NPC), the proportion of WHO type I NPC in Japan are different from that in non-endemic areas such as North America and Europe. Recently, it is said that not only Epstein-Barr virus (EBV) but also human papillomavirus (HPV) has an influence on NPC in non-endemic areas. The aim of this study is to clarify the influence of HPV on NPC in Japan. Paraffin-embedded tumor specimens were available for 59 patients with NPC diagnosed between 1996 and 2015. We detected the virus status by p16 immunohistochemistry, HPV PCR, and in situ hybridization for Epstein-Barr virus (EBV)-encoded RNA. Kaplan-Meier curves were used to compare the overall survival by viral status. Among the 59 patients, 49 (83%) were EBV-positive/HPV-negative, 2 (3%) were EBV-positive/HPV-positive, and 8 (16%) were EBV-negative/HPV-negative. All HPV-positive NPCs were co-infected with EBV. There were no significant differences between the overall survival in the three groups (p=0.111). In Japan, HPV was detected in a few patients with NPC, and we suggest that HPV has no influence on NPC carcinogenesis in this population. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Predictors of the highest long-term care expenditures in Japan

PubMed Central

2011-01-01

Background In Japan, as the number of elderly covered by the Long-term Care Insurance (LTCI) system has increased, demand for long-term care services has increased substantially and consequently growing expenditures are threatening the sustainability of the system. Understanding the predictive factors associated with long-term care expenditures among the elderly would be useful in developing future strategies to ensure the sustainability of the system. We report a set of predictors of the highest long-term care expenditures in a cohort of elderly persons who received consecutive long-term care services during a year in a Japanese city. Methods Data were obtained from databases of the LTC insurer of City A in Japan. Binary logistic regression was used to examine the predictors of the highest long-term care expenditures. We used a simplified model that focused on the effects of disability status and type of services used, while controlling for several relevant factors. Goodness of fit, a multicollinearity test, and logistic regression diagnostics were carried out for the final model. Results The study cohort consisted of 862 current users of LTCI system in city A. After controlling for gender and income, age, increased utilization rate of benefits, decline in functional status, higher care needs level and institutional care were found to be associated with the highest LTCI expenditures. An increased utilization rate of benefits (OR = 24.2) was a strong main effect predictors of the high LTC expenditures. However, a significant interaction between institutional care and high care need level was found, providing evidence of the combined effect of the two covariates. Conclusions Beyond to confirm that disability status of elderly persons is the main factor driving the demand of LTC services and consequently the expenditures, we showed that changes in utilization rate of benefits -a specific insurance factor- and the use of institutional care conditional on the high care

Thermally stimulated current (TSC) measurement is widely used in a variety of research fields, i.e., physics, electronics, electrical engineering, chemistry, ceramics, and biology. TSC is short-circuit current that flows owing to the displacement of charges in samples during heating. TSC measurement is very simple, but TSC curves give very important information on charge behaviors. In the 1970s, TSC measurement contributed greatly to the development of electrical insulation engineering, semiconductor device technology, and so forth. Accordingly, the TSC experimental technique and its analytical method advanced. Over the past decades, many new molecules and advanced functional materials have been discovered and developed. Along with this, TSC measurement has attracted much attention in industries and academic laboratories as a way of characterizing newly discovered materials and devices. In this review, we report the latest research trend in the TSC method for the development of materials and devices in Japan.

The ALMA Science Pipeline is being developed for the automated calibration and imaging of ALMA interferometric and single-dish data. The calibration Pipeline for interferometric data was accepted for use by ALMA Science Operations in 2014, and for single-dish data end-to-end processing in 2015. However, work is ongoing to expand the use cases for which the Pipeline can be used e.g. for higher frequency and lower signal-to-noise datasets, and for new observing modes. A current focus includes the commissioning of science target imaging for interferometric data. For the Single Dish Pipeline, the line finding algorithm used in baseline subtraction and baseline flagging heuristics have been greately improved since the prototype used for data from the previous cycle. These algorithms, unique to the Pipeline, produce better results than standard manual processing in many cases. In this poster, we report on the current status of the Pipeline capabilities, present initial results from the Imaging Pipeline, and the smart line finding and flagging algorithm used in the Single Dish Pipeline. The Pipeline is released as part of CASA (the Common Astronomy Software Applications package).

A review of national and international publications on paragonimiasis in Ecuador, epidemiological records from the Ministry of Public Health and unpublished research data was conducted to summarise the current status of the parasite/disease. The purpose of the review is to educate physicians, policy-makers and health providers on the status of the disease and to stimulate scientific investigators to conduct further research. Paragonimiasis was first diagnosed in Ecuador 94 years ago and it is endemic to both tropical and subtropical regions in 19 of 24 provinces in the Pacific Coast and Amazon regions. Paragonimus mexicanus is the only known species in the country, with the mollusc Aroapyrgus colombiensis and the crabs Moreirocarcinus emarginatus, Hypolobocera chilensis and Hypolobocera aequatorialis being the primary and secondary intermediate hosts, respectively. Recent studies found P. mexicanus metacercariae in Trichodactylus faxoni crabs of the northern Amazon. Chronic pulmonary paragonimiasis is commonly misdiagnosed and treated as tuberculosis and although studies have demonstrated the efficacy of praziquantel and triclabendazole for the treatment of human infections, neither drug is available in Ecuador. Official data recorded from 1978-2007 indicate an annual incidence of 85.5 cases throughout the 19 provinces, with an estimated 17.2% of the population at risk of infection. There are no current data on the incidence/prevalence of infection, nor is there a national control programme. PMID:25410987

Male acceptance of condoms in Japan.

PubMed

Uchida, Y

1981-01-01

Current surveys indicate that more than 70% of married couples in Japan use condoms as their primary contraceptive method. The popularity of condoms is due to the oral contraceptive (OC) pills not being recognized as safe forms of contraception and IUDs not being legalized by the government until 1974. The history of condom use in Japan goes back to 1872 when condoms of thin leather were imported into Japan from England and France. Manufacturing of condoms in Japan began in 1909, mainly as a method for venereal disease prevention. The condom and induced abortion are now the major methods of contraception. 60% of the distribution of condoms is through pharmacies and cosmetic stores; 50% of the buyers are women. Since 1955, teams of family planning workers have distributed condoms by selling on a door-to-door basis, especially to lower middle class couples. Between 1969-75, 75% of contraceptive users were using condoms. Currently there are 81% users. The rhythm method ranks second in popularity at 30% between 1969-75. OCs have gradually increased recently to 3% users, but side effects have deterred people from selecting them. The proportion of IUD users has remained at a consistently low level for the past several years. Japan accounts for 1/3 of the total world production of condoms.

Chinese dental technicians play a significant role in the globalised market of dental prosthesis fabrication, but this subject has not been investigated in detail. The demand for dental prostheses increases as individuals pay increasing attention to their oral health. Therefore, it is important to investigate the status of Chinese dental technicians. To evaluate the current status of Chinese dental technicians. Dental technicians' resumés, which reveal information regarding dental technician manpower, degrees, working age and salary, etc., were analysed and compared with those abroad. We also estimated the future demands of dental technician manpower, and discussed some potential solutions. There are fewer dental technicians in China than in other developed countries; they are also of a lower standard. Male technicians outnumber females. The education level of technicians is insufficient, and the education programme is still in its exploratory stage. The development of dental technician teams in China represents both an opportunity and a challenge. It is important to move forward from the current situation to yield long-term development. This article provides information on the Chinese dental technology industry, identifies the problems and offers solutions for its development. © 2012 FDI World Dental Federation.

In many countries, HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) infected individuals may face discrimination and mistreatment from coworkers. Effective interventions to reduce workplace discrimination are therefore needed to protect these vulnerable populations. The current study investigated potential associations between sociodemographic factors and prejudice toward HIV and HBV/HCV infected colleagues within a Japanese working population. An online anonymous, nationwide internet survey was administered to a cross-section of approximately 3,000 individuals in Japan. The survey comprised 14 questions focusing on demographics (five items), basic HIV or HBV/HCV knowledge (eight items), and potential prejudice toward HIV or HBV/HCV infected colleagues (one item). The sociodemographic characteristics evaluated were sex, age, educational level, employment status, and individual income; with multiple logistic regression used for the analysis. In total, 3,055 individuals were recruited for the HIV related survey and 3,129 for the HBV/HCV related survey. Older age was significantly and positively associated with prejudice toward HIV infected colleagues (p<0.01) and negatively associated with prejudice toward HBV/HCV infected colleagues (p<0.01). Statistically significant associations were not observed between other sociodemographic characteristics and potential prejudice toward HIV and HBV/HCV infected coworkers. Overall, this study suggests that age may be associated with prejudice toward HIV and HBV/HCV infected colleagues among the working age population of Japan. As such, policy makers should consider the age of participants when formulating efforts to reduce prejudice toward HIV and HBV/HCV infected workers.

Internet Medical Usage in Japan: Current Situation and Issues

PubMed Central

Mitani, Hiroaki; Haruki, Yasuo; Ogushi, Youichi

2001-01-01

Internet use by physicians and patients has become very popular in Japan. Fifty percent of physicians use the Internet to search for medical and other information. Over the past year, 22% of patients used the Internet to obtain medical information. Because there are no restrictions within Japan on using Web sites to advertise medical treatment, information can be freely sent out, and over the past two or three years this practice has increased dramatically. Internet medical information provides information about illnesses and medications, and it helps improve the quality of life of patients and families. Yet, depending on the content of the information provided and the way this information is used, there is a potential negative side as well. On principle, users are responsible for the way information is used, but there is a need for information providers to consider users' safety and to make the information effective for use. Because there is no absolute standard for evaluating the value of medical information, it is necessary to establish a system that opens a dialogue with society and that continuously accumulates high-quality information through the collection of various evaluations, rather than rely on an established authority. For industries and organizations related to commercial pursuits, in particular, it is most effective to establish their own codes for ethical conduct, rather than rely on governmental regulations. At the same time, it is important to have a confirmation function to evaluate how goals set by the outside are being implemented. Aiming at establishing a framework for the Internet medical usage, the Japan Internet Medical Association (JIMA) was founded in 1998 by medical professionals, lawyers, researchers, consumer representatives, patients and their families. We propose a system that would combine feedback from users, who would take on the role of evaluators of the implementation of an ethical code, with a displayed mark that verifies the

Japan is composed of 4 main islands and more than 3900 smaller islands and has 317.7 persons/square kilometer. This makes it one of the most densely populated nations in the world. Religion is an important force in the life of the Japanese and most consider themselves Buddhists. Schooling is free through junior high but 90% of Japanese students complete high school. In fact, Japan enjoys one of the highest literacy rates in the world. There are over 178 newspapers and 3500 magazines published in Japan and the number of new book titles issued each year is greater than that in the US. Since WW1, Japan expanded its influence in Asia and its holdings in the Pacific. However, as a direct result of WW2, Japan lost all of its overseas possessions and was able to retain only its own islands. Since 1952, Japan has been ruled by conservative governments which cooperate closely with the West. Great economic growth has come since the post-treaty period. Japan as a constitutional monarchy operates within the framework of a constitution which became effective in May 1947. Executive power is vested in a cabinet which includes the prime minister and the ministers of state. Japan is one of the most politically stable of the postwar democracies and the Liberal Democratic Party is representative of Japanese moderate conservatism. The economy of Japan is strong and growing. With few resources, there is only 19% of Japanese land suitable for cultivation. Its exports earn only about 19% of the country's gross national product. More than 59 million workers comprise Japan's labor force, 40% of whom are women. Japan and the US are strongly linked trading partners and after Canada, Japan is the largest trading partner of the US. Foreign policy since 1952 has fostered close cooperation with the West and Japan is vitally interested in good relations with its neighbors. Relations with the Soviet Union are not close although Japan is attempting to improve the situation. US policy is based on

The effect of micro and macro stressors in the work environment on computer professionals' subjective health status and productive behavior in Japan.

2007-06-01

To investigate the effect of micro and macro stressors in the work environment on the subjective health status and productive behavior of computer professionals, we conducted a web-based investigation with Japanese IT-related company employees in 53 company unions. The questionnaire consisted of individual attributes, employment characteristics, working hour characteristics, company size and profitability, personal characteristics (i.e., Growth Need Strength), micro and macro stressors scale, and four outcome scales concerning the subjective health status and productive behavior. We obtained 1,049 Japanese IT-related company employees' data (response rate: 66%), and analyzed the data of computer engineers (80%; n=871). The results of hierarchical multiple regressions showed that each full model explained 23% in psychological distress, 20% in cumulative fatigue, 44% in job dissatisfaction, and 35% in intentions to leave, respectively. In micro stressors, "quantitative and qualitative work overload" had the strongest influence on both the subjective health status and intentions to leave. Furthermore, in macro stressors, "career and future ambiguity" was the most important predictor of the subjective health status, and "insufficient evaluation systems" and "poor supervisor's support" were important predictors of productive behavior as well. These findings suggest that improving not only micro stressors but also macro stressors will enhance the subjective health status and increase the productive behavior of computer professionals in Japan.

Reports on drug-related adverse reactions from manufacturing/distributing pharmaceutical companies or medical institutions/pharmacies are regulated under the Pharmaceutical Affairs Law of Japan, and this system is important for post-marketing safety measures. Although association between the medicine and the adverse event has not been clearly evaluated, and an incidence may be redundantly reported, this information would be useful to roughly grasp the current status of drug-related adverse reactions. In the present study, we analyzed the incidence of drug-induced liver injury by screening the open-source data publicized by the homepage of Pharmaceutical and Medical Devices Agency from 2005 to 2011 fiscal years. Major drug-classes suspected to cause general drug-induced liver injury were antineoplastics, anti-inflammatory agents/common cold drugs, chemotherapeutics including antituberculous drugs, antidiabetics, antiulcers and antiepileptics. In addition, reported cases for fulminant hepatitis were also summarized. We found that antituberculous isoniazid and antineoplastic tegafur-uracil were the top two suspected drugs. These results might deepen understanding of current situations for the drug-induced liver injury in Japan.

The successful implementation of a strategy to produce high-definition systems within the Japanese economy will favorably affect the fundamental competitiveness of Japan relative to the rest of the world. The development of an infrastructure necessary to support high-definition products and systems in that country involves major commitments of engineering resources, plants and equipment, educational programs and funding. The results of these efforts appear to affect virtually every aspect of the Japanese industrial complex. The results of assessments of the current progress of Japan toward the development of high-definition products and systems are presented. The assessments are based on the findings of a panel of U.S. experts made up of individuals from U.S. academia and industry, and derived from a study of the Japanese literature combined with visits to the primary relevant industrial laboratories and development agencies in Japan. Specific coverage includes an evaluation of progress in R&D for high-definition television (HDTV) displays that are evolving in Japan; high-definition standards and equipment development; Japanese intentions for the use of HDTV; economic evaluation of Japan's public policy initiatives in support of high-definition systems; management analysis of Japan's strategy of leverage with respect to high-definition products and systems.

Japan consists of 3900 islands and lies off the east coast of Asia. Even though Japan is one of the most densely populated nations in the world, its growth rate has stabilized at .5%. 94% of all children go to senior high school and almost 90% finish. Responsibility for the sick, aged, and infirmed is changing from the family and private sector to government. Japan was founded in 600 BC and its 1st capital was in Nara (710-1867). The Portuguese, the 1st Westerners to make contact with Japan in 1542, opened trade which lasted until the mid 17th century. US Navy Commodore Matthew Perry forced Japan to reopen in 1854. Following wars with China and Russia in the late 1800s and early 1900s respectively, Japan took part in World Wars I and II. In between these wars Japan invaded Manchuria and China. The US dropped an atomic bomb on Hiroshima and Nagasaki and the Japanese surrendered in September, 1945 ending World War II (WWII). Following, WWII, the Allied Powers guided Japan's establishment as a nonthreatening nation and a democratic parliamentary government (a constitutional monarchy) with a limited defense force. Japan remains one of the most politically stable of all postwar democracies. The Liberal Democratic Party's Noboru Takeshita became prime minister in 1987. Japan has limited natural resources and only 19% of the land is arable. Japanese ingenuity and skill combine to produce one of the highest per hectare crop yields in the world. Japan is a major economic power, and its and the US economies are becoming more interdependent. Its exports, making up only 13% of the gross national product, mainly go to Canada and the US. Many in the US are concerned, however, with the trade deficit with Japan and are seeking ways to make trade more equitable. Japan wishes to maintain good relations with its Asian neighbors and other nations. The US and Japan enjoy a strong, productive relationship.

This report summarizes the status of electronic manufacturing and packaging technology in Japan in comparison to that in the United States, and its impact on competition in electronic manufacturing in general. In addition to electronic manufacturing technologies, the report covers technology and manufacturing infrastructure, electronics manufacturing and assembly, quality assurance and reliability in the Japanese electronics industry, and successful product realization strategies. The panel found that Japan leads the United States in almost every electronics packaging technology. Japan clearly has achieved a strategic advantage in electronics production and process technologies. Panel members believe that Japanese competitors could be leading U.S. firms by as much as a decade in some electronics process technologies.

A survey of scientific literacy to provide a foundation for designing science communication in Japan.

PubMed

2013-08-01

There are various definitions and survey methods for scientific literacy. Taking into consideration the contemporary significance of scientific literacy, we have defined it with an emphasis on its social aspects. To acquire the insights needed to design a form of science communication that will enhance the scientific literacy of each individual, we conducted a large-scale random survey within Japan of individuals older than 18 years, using a printed questionnaire. The data thus acquired were analyzed using factor analysis and cluster analysis to create a 3-factor/4-cluster model of people's interest and attitude toward science, technology and society and their resulting tendencies. Differences were found among the four clusters in terms of the three factors: scientific factor, social factor, and science-appreciating factor. We propose a plan for designing a form of science communication that is appropriate to this current status of scientific literacy in Japan.

Investigation from Japanese MAGSAT Team. Part A. Crustal structure near Japan and in Antarctic station. Part B. Electric currents and hydromagnetic waves in the ionosphere and the magnetosphere

1981-01-01

Preliminary results of MAGSAT data analysis are described. Regional anomaly maps (deviations from the MGST model field) for X,Y,Z, and F in the area of 115 to 155 deg E and 20 to 60 deg N were obtained. A similar map for the geomagnetic total force anomaly in the vicinity of Japan showed that the observed anomaly can be explained by the difference in crustal magnetization between the Japan Sea and the Japan Island, which reflects a difference of 25 km in the thickness of the magnetized layer. The MAGSAT record of a sudden commencement of a magnetic storm above the South Atlantic Ocean showed a reverse impulse particularly in the D-component. Results relating to toroidal currents in the ionosphere, transverse and parallel perturbations over the polar regions, the relationship between field aligned currents and precipitating electrons, and the calculation of the subsatellite electric field are also discussed.

This paper describes the current status of percutaneous coronary intervention (PCI) for totally occluded coronary arteries. Chronic total occlusion is associated with 10%–20% of all PCI procedures. Results show that opening an occluded vessel, especially one supplying a considerable area of myocardium, may be beneficial for a patient’s angina relief and heart function. We describe the devices used currently in re-canalization such as new wires, microcatheters (including Tonus and Cosair) and intravascular ultrasound guidance. Different techniques to improve the success rate and reduce complications are discussed in detail. PMID:22843178

2004-08-01

Clinical trials of hyperthermia in combination with radiation therapy or chemotherapy undertaken over the past decades in Japan have been reviewed. Originally developed heating devices were mostly used for these trials, which include RF (radiofrequency) capacitive heating devices, a microwave heating device with a lens applicator, an RF intracavitary heating device, an RF current interstitial heating device, and ferromagnetic implant heating device. Non-randomized trials for various cancers, demonstrated higher response rate in thermoradiotherapy than in radiotherapy alone. Randomized trials undertaken for esophageal cancers also demonstrated improved local response with the combined use of hyperthermia. Furthermore, the complications associated with treatment were not generally serious. These clinical results indicate the benefit of combined treatment of hyperthermia and radiotherapy for various malignancies. On the other hand, the presently available heating devices are not satisfactory from the clinical viewpoints. With the advancement of heating and thermometry technologies, hyperthermia will be more widely and safely used in the treatment of cancers.

Yoshiyama, Kenji; Kazui, Hiroaki; Takeda, Masatoshi

2015-09-01

We used a questionnaire to evaluate how patients with idiopathic normal-pressure hydrocephalus (iNPH) are examined in Medical Centers for Dementia (MCDs), which are qualified medical organizations for dementia patients in Japan. Ninety-eight of 205 MCDs responded to our questionnaire. Accordingly, more than 590 patients with iNPH underwent an MCD examination during the period of 1 year. In regards to the Guidelines for Management of iNPH, 40 of the 98 MCDs used neither the first nor second edition of the Guidelines, even though up-to-date information is available in the second edition of the Guidelines. At most MCDs, consultation with iNPH specialists was performed without a cerebrospinal fluid tap test. At more than half of the responding MCDs, doctors felt that the selection of appropriate candidates for shunt surgery differed from those selected by neurosurgeons. Moreover, 73 out of 87 MCDs argued that patients with iNPH should be examined by both dementia specialists and neurosurgeons after shunt surgery. These results suggest that doctors at MCDs should take advantage of up-to-date information and cooperate with iNPH specialists and neurosurgeons.

The opisthobranch fauna (Gastropoda: Opisthobranchia) of the deep sea basins of the Sea of Japan is reviewed. A detailed description of the most common deep sea nudibranch species Coryphella japonicaVolodchenko, 1941 is given based on materials from various expeditions (including R/V "Vityaz" cruises and SoJaBio project). Distinct morphological features of C. japonica are discussed and its valid taxonomic status is confirmed. The considerable radular variability of C. japonica for the first time is documented using a scanning electron microscope. Unique features of the bathymetric distribution of C. japonica ranging from shelf to the abyssal depths are discussed in connection with the "pseudabyssal area" concept. C. japonica was compared to its assumed synonym C. salmonacea, and to similar C. athadona. Material from all these species, including types of C. japonica, was examined externally, anatomically via dissection, and SEM. C. salmonacea is restricted to North Atlantic and Arctic only, whereas C. japonica inhabits NE Pacific including deep water basins of the Sea of Japan.

We investigated the current activities of medical centers for dementia (MCD), and proposed recommendations for a national dementia strategy. A questionnaire was mailed to 172 hospitals designated as MCD as of 7 August 2012. Data from 117 MCD that adequately responded and were designated by 1 April 2012 were analyzed. The mean and median numbers of medical consultations per MCD were 1035 and 595/year (range 114-8541/year), those of patients diagnosed with dementia-related disorders were 266 and 231/year (range 3-1179/year), those of patients with dementia-related disorders admitted to the MCD hospital were 89 and 47/year (0-1176/year), and mean and median proportions of patients discharged within 2 months were 45.5 and 36.8% (range 0-100%). Outreach services in collaboration with a community general support center were provided in 23.9%, while training for community general support center staff members was carried out in 66.7%. Of MCD hospitals, 31.6% were designated as an emergency medical hospital, and of these, specialist liaison-team services for patients with dementia in the emergency room were provided in 56.8%. Most MCD are considered to function fairly well in line with the guidelines published by the Ministry of Health, Labour and Welfare. However, there is a huge discrepancy in the number of patients diagnosed with dementia-related disorders and the length of stay for inpatient care among facilities. To make all MCD function adequately, the activity of MCD should be monitored longitudinally using the standardized assessment methods. © 2014 Japan Geriatrics Society.

The current status of the Nano-JASMINE project is reported. Nano-JASMINE is a very small-sized (50 cm cubic form) satellite that is expected to carry out astrometric observations of nearby bright stars. The satellite will determine distances of more than 8000 stars by performing annual parallax measurements, which is the only direct method to measure the distance of an astronomical object. The mission is required to continue for more than two years to obtain reliable annual parallax measurements. In addition, Nano-JASMINE will serve as a preliminary to the main JASMINE mission. We expect that Nano-JASMINE will be launched in August 2011 from the Alcantara Space Center in Brazil using the Cyclone-4 rocket.

2009-09-01

No public consensus exists yet on handling Biosafety Level 4 agents and no laboratory is operational at BSL4 in Japan. A discussion that includes neighboring residents and experts should be initiated to communicate risks. In this article, we present the current situation and prioritize problems we presently face. A three-stage Delphi survey was conducted. The subjects were twenty-two persons with extensive experience and knowledge of infectious diseases. Seven projections and issues were made with regard to the problems arising from the lack of an operational BSL4 laboratory. These were tabulated by the KJ method. The top seven projections were scored, such that the top received 7 points and the last received 1 point. A total of 51 projections were obtained for the first part of the survey, 39 for the second, and 29 for the last. The projection with the highest score was that it is impossible to cope with newly emerging infectious diseases. The second was that complete diagnoses are impossible without a BSL4 laboratory. All projections and issues were divided into the following four main groups: issues for researchers and laboratory staff, clinical practice and research on BSL4 agents, domestic and global security, and Japan's international position. We clarified possible problem arising from not having BSL4 laboratories in Japan. The identification of projections by the Delphi survey in this study should be considered as one of many attempts to develop effective risk communication strategies.

Homeless veterans are at high risk for co-occurring disorders (COD), defined as mental illnesses that include at least one alcohol or other drug use disorder and at least one non-drug related mental disorder. However, epidemiological studies examining the prevalence of COD and associated mental health status in this population are limited. The objectives of the study were: (1) to describe a history of diagnosed mental disorders among homeless veterans admitted to a transitional housing program, and (2) to examine the associations of the prior diagnosed COD and other mental disorders with current mental health status. Study participants were male homeless veterans admitted to a transitional housing program from July 2015 to September 2017 in a large municipal area in Northeast Ohio, the United States. Cross-sectional, self-reported data from the admission assessment were included and analyzed. History of mental disorder diagnoses were aggregated into five categories for the purpose of this study: no mental disorders, only alcohol or other drug use disorder(s), one non-drug related mental disorder, two or more non-drug related mental disorders, and COD. Current mental status were measured as empowerment, mental component summary score (MCS) and physical component summary score (PCS) of health related quality of life (VR-12), and perceived overall well-being. Sample distribution of the five categories and their associations with current mental status were examined using Generalized Linear Model test. Of all participants, 76.7% had at least one prior diagnosed mental disorder, including 47.4% with any drug-related disorders. Over one-third (37.2%) reported having COD. Compared to those with no mental disorder history, those with COD scored significantly lower on MCS and empowerment scores; those with any prior diagnosed non-drug related mental disorders also scored significantly lower on MCS. No significant differences, however, were found in current mental health

The world's first diagnostic criteria for early CP were proposed in 2009 in Japan. This study aimed to clarify the clinico-epidemiological features of early CP in Japan. Patients with early CP who were diagnosed according to the diagnostic criteria for early CP and had visited the selected hospitals in 2011 were surveyed. The study consisted of two-stage surveys: the number of patients with early CP was estimated by the first questionnaire and their clinical features were assessed by the second questionnaire. The estimated number of early CP patients was 5410 (95% confidence interval 3675-6945), with an overall prevalence of 4.2 per 100,000 persons. The number of patients who were newly diagnosed with early CP was estimated to be 1330 (95% confidence interval 1058-1602), with an annual incidence of 1.0 per 100,000 persons. Detailed clinical information was obtained in 151 patients in the second survey. The male-to-female sex ratio was 1.32:1. The mean age was 60.4 and the mean age at disease onset was 55.4. Idiopathic (47.7%) and alcoholic (45.0%) were the two most common etiologies. Proportions of female and idiopathic cases were higher in early CP than in definite CP. Hyperechoic foci without shadowing and stranding were the most common findings on endoscopic ultrasonography. The clinical profiles of early CP patients who showed lobularity with honeycombing on endoscopic ultrasonography or previous episodes of acute pancreatitis were similar to those of definite CP patients. We clarified the current status of early CP in Japan.

Identifying the strengths and weakness points is one of the effective methods to analyze current status, and prioritizing actions based on the gap between current and optimal status is necessary for short-term and long-term planning in departments and colleges. The aim of this study was to determine the gap between current and optimal status of curriculum leadership in the postgraduate courses in two Iranian universities. In this cross-sectional study, a sample of 212 faculty members from the two Iranian universities (one medical and one nonmedical) was randomly selected through stratified random sampling method. Data were collected by using a researcher-made questionnaire, with 55 items categorized in four areas of main dimensions in curriculum leadership. The validity of the questionnaire was determined by curriculum studies scholars, and the reliability was confirmed as the Cronbach's alpha calculated 0.969. Data were analyzed using descriptive and inferential statistics according to the variables. There was a gap in all dimensions and roles. The maximum gap (-1.70) with the highest frequency (98%) were related to "improving the educational atmosphere" dimension. As for items, the maximum gap (-2.41) was related to "society needs and expectations and the labor market" in "curriculum development and revision" dimension. The negative gap between all dimensions of curriculum leadership implies faculty members' dissatisfaction. Curriculum leadership at universities, colleges and departments of the study in all aspects need to be improved. Hence, it is necessary for managers to make use of the viewpoints of the faculty members to decrease the gap.

R&D activities on photonic networks in Japan are presented. First, milestones in current ongoing R&D programs supported by Japanese government agencies are introduced, including long-distance and wavelength division multiplexing (WDM) fiber transmission, wavelength routing, optical burst switching (OBS), and control-plane technology for IP backbone networks. Their goal was set to evolve a legacy telecommunications network to IP-over-WDM networks by introducing technologies for WDM and wavelength routing. We then discuss the perspectives of so-called PHASE II R&D programs for photonic networks over the next 5 years until 2010, by focusing on the report that has been recently issued by the Photonic Internet Forum (PIF), a consortium that has major carriers, telecom vendors, and Japanese academics as members. The PHASE II R&D programs should serve to establish a photonic platform to provide abundant bandwidth on demand, at any time on a real-time basis, through the customer's initiative to promote bandwidth-rich applications, such as grid computing, real-time digital-cinema streaming, medical and educational applications, and network storage in e-commerce.

Tombs, tunnels, and terraces a cultural resources survey of a former ammunition supply point in Okinawa, Japan

U.S. forces serving at military bases on foreign soil are obligated to act as good stewards of the cultural and natural resources under their control. However, cultural resources management presents special challenges at U.S. bases in other countries where cultural properties laws differ in emphasis and detail from those in the United States and issues of land ownership and occupancy are not always clear. Where status of forces agreements (SOFAs) exist, environmental governing standards bridge the gap between U.S. and host nation cultural priorities. In Japan, the Department of Defense Japan Environmental Governing Standards (JEGS) fill this function. Under Criteriamore » 12-4.2 and 12-4.3 of the JEGS, U.S. Forces Japan commit themselves to inventory and protect cultural properties found on the lands they control or use. Cultural properties include archaeological sites, tombs, historic buildings, and shrines.

Assessing age-dependent susceptibility to measles in Japan.

PubMed

Kinoshita, Ryo; Nishiura, Hiroshi

2017-06-05

Routine vaccination against measles in Japan started in 1978. Whereas measles elimination was verified in 2015, multiple chains of measles transmission were observed in 2016. We aimed to reconstruct the age-dependent susceptibility to measles in Japan so that future vaccination strategies can be elucidated. An epidemiological model was used to quantify the age-dependent immune fraction using datasets of vaccination coverage and seroepidemiological survey. The second dose was interpreted in two different scenarios, i.e., booster and random shots. The effective reproduction number, the average number of secondary cases generated by a single infected individual, and the age at infection were explored using the age-dependent transmission model and the next generation matrix. While the herd immunity threshold of measles likely ranges from 90% to 95%, assuming that the basic reproductive number ranges from 10 to 20, the estimated immune fraction in Japan was below those thresholds in 2016, despite the fact that the estimates were above 80% for all ages. If the second dose completely acted as the booster shot, a proportion immune above 90% was achieved only among those aged 5years or below in 2016. Alternatively, if the second dose was randomly distributed regardless of primary vaccination status, a proportion immune over 90% was achieved among those aged below 25years. The effective reproduction number was estimated to range from 1.50 to 3.01 and from 1.50 to 3.00, respectively, for scenarios 1 and 2 in 2016; if the current vaccination schedule were continued, the reproduction number is projected to range from 1.50 to 3.01 and 1.39 to 2.78, respectively, in 2025. Japan continues to be prone to imported cases of measles. Supplementary vaccination among adults aged 20-49years would be effective if the chains of transmission continue to be observed in that age group. Copyright © 2017 Elsevier Ltd. All rights reserved.

Polycystic ovary syndrome: current status and future perspective

PubMed Central

Barthelmess, Erin K.; Naz, Rajesh K.

2015-01-01

Polycystic ovary syndrome (PCOS) is a widespread reproductive disorder that encompasses many associated health conditions and has an impact on various metabolic processes. PCOS is depicted by hyperandrogenism, polycystic ovaries, and anovulation. It increases the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. The etiology of the disease remains unclear, and the subjective phenotype makes a united diagnosis difficult among physicians. It seems to be a familial genetic syndrome caused by a combination of environmental and genetic factors. It can be linked with metabolic disorders in first-degree family members. PCOS is the cause of up to 30% of infertility in couples seeking treatment. Currently, there is no cure for PCOS. Despite the growing incidence of this syndrome, limited research has been done that encompasses the entirety of PCOS spectrum. In this review, the current status and possible future perspective will be discussed. PMID:24389146

Map of Pseudo-F-statistics of seismic noise parameters as an indicator of current seismic danger in Japan

NASA Astrophysics Data System (ADS)

Lyubushin, Alexey

2016-04-01

The problem of estimate of current seismic danger based on monitoring of seismic noise properties from broadband seismic network F-net in Japan (84 stations) is considered. Variations of the following seismic noise parameters are analyzed: multifractal singularity spectrum support width, generalized Hurst exponent, minimum Hölder-Lipschitz exponent and minimum normalized entropy of squared orthogonal wavelet coefficients. These parameters are estimated within adjacent time windows of the length 1 day for seismic noise waveforms from each station. Calculating daily median values of these parameters by all stations provides 4-dimensional time series which describes integral properties of the seismic noise in the region covered by the network. Cluster analysis is applied to the sequence of clouds of 4-dimensional vectors within moving time window of the length 365 days with mutual shift 3 days starting from the beginning of 1997 up to the current time. The purpose of the cluster analysis is to find the best number of clusters (BNC) from probe numbers which are varying from 1 up to the maximum value 40. The BNC is found from the maximum of pseudo-F-statistics (PFS). A 2D map could be created which presents dependence of PFS on the tested probe number of clusters and the right-hand end of moving time window which is rather similar to usual spectral time-frequency diagrams. In the paper [1] it was shown that the BNC before Tohoku mega-earthquake on March 11, 2011, has strongly chaotic regime with jumps from minimum up to maximum values in the time interval 1 year before the event and this time intervals was characterized by high PFS values. The PFS-map is proposed as the method for extracting time intervals with high current seismic danger. The next danger time interval after Tohoku mega-EQ began at the end of 2012 and was finished at the middle of 2013. Starting from middle of 2015 the high PFS values and chaotic regime of BNC variations were returned. This could be

Sleep, serotonin, and suicide in Japan.

PubMed

Kohyama, Jun

2011-01-01

This article reviews evidence supporting the hypothesis that suicide rates in Japan could be reduced by elevating serotonin levels via increasing the average duration of sleep. Seven major relevant findings were apparent in the literature: 1) Sleep loss is associated with suicide, but the direction of causality is equivocal. 2) Decreased serotonergic activity may be involved in suicidal behavior. 3) Sleep debt may decrease serotonergic activity. 4) The suicide rate in Japan has remained at a heightened level for the past 12 years. 5) The average sleep duration in Japan has decreased over the past 40 years. 6) The average sleep duration in Japan is among the lowest in the world. 7) The average sleep duration in Japan plateaued in 1995 and has been relatively stable since. From the research reviewed, two major problematic issues were apparent: 1) Most people in Japan receive inadequate sleep. 2) Individuals whose sleep is inadequate are unlikely to be sufficiently physically active to stimulate serotonergic systems to a desirable level. I propose that public health initiatives encouraging a longer duration of sleep may provide a relatively simple way of addressing the disturbing current trend in Japan. The combination of actigraph and brain serotonin level measurement could allow large population-based cohort studies to be designed, to elucidate the causal links between sleep duration, serotonin levels, and suicide rates.

The infection-and-treatment method (ITM) for immunization of cattle against East Coast fever has historically been used only on a limited scale because of logistical and policy constraints. Recent large-scale deployment among pastoralists in Tanzania has stimulated demand. Concurrently, a suite of molecular tools, developed from the Theileria parva genome, has enabled improved quality control of the immunizing stabilate and post-immunization monitoring of the efficacy and biological impact of ITM in the field. This article outlines the current status of ITM immunization in the field, with associated developments in the molecular epidemiology of T. parva.

Recent guidelines have encouraged gastroenterology and surgical training programs to integrate simulation into their core endoscopic curricula. However, the role that simulation currently has within training programs is unknown. This study aims to assess the current status of simulation among gastroenterology fellowship programs. This questionnaire study consisted of 38 fields divided into two sections. The first section queried program directors' experience on simulation and assessed the current status of simulation at their institution. The second portion surveyed their opinion on the potential role of simulation on the training curriculum. The study was conducted at the 2013 American Gastroenterological Association Training Directors' Workshop in Phoenix, Arizona. The participants were program directors from Accreditation Council for Graduate Medical Education accredited gastroenterology training programs, who attended the workshop. The questionnaire was returned by 69 of 97 program directors (response rate of 71%). 42% of programs had an endoscopic simulator. Computerized simulators (61.5%) were the most common, followed by mechanical (30.8%) and animal tissue (7.7%) simulators, respectively. Eleven programs (15%) required fellows to use simulation prior to clinical cases. Only one program has a minimum number of hours fellows have to participate in simulation training. Current simulators are deemed as easy to use (76%) and good educational tools (65%). Problems are cost (72%) and accessibility (69%). The majority of program directors believe that there is a need for endoscopic simulator training, with only 8% disagreeing. Additionally, a majority believe there is a role for simulation prior to initiation of clinical cases with 15% disagreeing. Gastroenterology fellowship program directors widely recognize the importance of simulation. Nevertheless, simulation is used by only 42% of programs and only 15% of programs require that trainees use simulation prior to

Cystic fibrosis (CF) is one of the most frequent monogenic disease in the Caucasian population, inherited in an autosomal recessive pattern. This is a multiple organ disease and its main manifestations include pulmonary and gastrointestinal dysfunction. The exocrine pancreatic deficiency results in impaired digestion and absorption what may lead to malnutrition and vitamins and minerals deficiencies. The life expectancy of cystic fibrosis patients has been increasing over the past years, so there is a need to verify usefulness of existing or create new methods of nutritional status assessment. The aim of this paper was presentation current data on the methods of assessment and monitoring of nutritional status. Particular attention has been paid to appropriate nutritional support in prevention and treatment of malnutrition patients with cystic fibrosis. On the basis of recent literature we can conclude that the advanced nutritional status assessment is recommended in patient with CF by using anthropometrical methods, body composition analysis and biochemical data. Good nutritional status is connected with pulmonary functions, quality and life length. © 2015 MEDPRESS.

Distribution of tick-borne diseases in Japan: Past patterns and implications for the future.

Yamaji, Kayoko; Aonuma, Hiroka; Kanuka, Hirotaka

2018-04-20

The rapid geographical spread of tick-borne diseases (TBDs) worldwide has recently provoked significant concerns amongst public health authorities. Tick-borne pathogens are maintained in enzootic cycles involving ticks and wild animal hosts, with epizootic spread to other mammals, including livestock and humans. Despite the increasing public health concern, current TBD diagnostic tests and treatments are inadequate, and predictive models of future risks posed by TBDs are limited by the heterogeneity of environmental, vector, and host factors, even in neighboring regions. In recent years, infections resulting in severe fever with thrombocytopenia syndrome (SFTS), Japanese spotted fever, and the scrub typhus pathogens have been reported frequently in addition to traditional TBDs in Japan. The Japanese archipelago is extremely elongated from north to south and its climate varies considerably, creating remarkable regional differences in tick species. The importance of continuous surveillance of TBDs has been growing in terms of geopathology - studies dealing with the relationships between geographic factors and the causes of specific diseases - in Japan and neighboring areas among eastern Asian countries, including China and Korea. In this review, we summarize detailed information regarding the history and epidemic status of human TBDs in Japan.

The direct and indirect effects of initial job status on midlife psychological distress in Japan: evidence from a mediation analysis.

PubMed

Oshio, Takashi; Inagaki, Seiichi

2015-01-01

In the current study, we investigated how initial job status at graduation from school is associated with midlife psychological distress, using microdata from a nationwide Internet survey of 3,117 men and 2,818 women aged 30-60 yr. We measured psychological distress using the Kessler 6 (K6) score (range: 0-24) and the binary variable of K6 score ≥5. We found that unstable initial job status substantially raised midlife K6 scores and the probability of a K6 score ≥5 for both men and women. Furthermore, our mediation analysis showed that for men, slightly less than 60% of the effect was mediated by current job status, household income, and marital status. For women, the effect of initial job status was somewhat lesser than that for men, and only 20-30% of it was mediated. Despite these gender asymmetries, the results indicated that initial job status was a key predictor of midlife mental health. The association between job status and mental health should be further investigated with special reference to the institutional attributes of the labor market and their socio-economic/demographic outcomes.

The Japan Atherosclerosis Society (JAS) has recommended serum lipid management goals (SLMGs) based on the coronary heart disease (CHD) risk classification included in its 2007 guidelines for the diagnosis and prevention of atherosclerotic cardiovascular disease in the Japanese population (JAS GL 2007). The Japan Society of Ningen Dock created a database of subjects receiving annual health examinations at 21 institutes nationwide. Using this database, we evaluated the efficacy of current treatment for patients with dyslipidemia by identifying risk factors for CHD development, based on the JAS recommendations. This multicenter, retrospective study was conducted using data obtained from 21 institutions across Japan. 17,991 adults taking dyslipidemia medications were enrolled. The JAS GL 2007 was used for evaluation. Since the guideline indicated separate goals (secondary prevention for subjects with a prior history of CHD and primary prevention for those with other CHD risk factors), we evaluated the percentages of goals met. The serum low-density lipoprotein cholesterol (LDL-C) levels were calculated using the Friedewald formula. The LDL-C level was measured using a direct homogeneous assay if the triglycerides (TG) level was 400 mg/dL or higher. The achievement rates of the SLMGs were as follows: LDL-C, 72.3%; high-density lipoprotein cholesterol (HDL-C), 94.6%; and TG, 69.7%. Our results regarding Japanese patients receiving dyslipidemia treatment for CHD prevention identified insufficient reductions in the levels of LDL-C and TG in those at high risk for CHD and suggest the need for more aggressive lipid-lowering therapy.

Background: Identifying the strengths and weakness points is one of the effective methods to analyze current status, and prioritizing actions based on the gap between current and optimal status is necessary for short-term and long-term planning in departments and colleges. The aim of this study was to determine the gap between current and optimal status of curriculum leadership in the postgraduate courses in two Iranian universities. Materials and Methods: In this cross-sectional study, a sample of 212 faculty members from the two Iranian universities (one medical and one nonmedical) was randomly selected through stratified random sampling method. Data were collected by using a researcher-made questionnaire, with 55 items categorized in four areas of main dimensions in curriculum leadership. The validity of the questionnaire was determined by curriculum studies scholars, and the reliability was confirmed as the Cronbach's alpha calculated 0.969. Data were analyzed using descriptive and inferential statistics according to the variables. Results: There was a gap in all dimensions and roles. The maximum gap (−1.70) with the highest frequency (98%) were related to “improving the educational atmosphere” dimension. As for items, the maximum gap (−2.41) was related to “society needs and expectations and the labor market” in “curriculum development and revision” dimension. Conclusion: The negative gap between all dimensions of curriculum leadership implies faculty members’ dissatisfaction. Curriculum leadership at universities, colleges and departments of the study in all aspects need to be improved. Hence, it is necessary for managers to make use of the viewpoints of the faculty members to decrease the gap. PMID:26109996

Child abuse and neglect in Japan: coin-operated-locker babies.

The coin-operated-locker baby is a type of child abuse that may be unique to Japan. The term refers to newborns who are placed, while alive or dead, in coin-operated lockers. This practice has been decreased by specific measures. It is likely that social and economic variables in Japan account for differences in the frequency and types of child abuse cases when compared to American or European societies as social conditions in Japan change the reported incidence of child abuse may increase in the future. Recently, the government of Osaka organized a group specifically designed to deal with the detection and protection of abused and neglected children. In 1993, they published a manual on how to deal with child abuse, but the Japanese judicial administration still uses old laws for abuse cases. The development of new laws is occurring in parts of the country now. This paper introduces the present status of coping with child abuse and neglect in Japan.

Status of sex reassignment surgery for gender identity disorder in Japan.

PubMed

Masumori, Naoya

2012-05-01

An incongruence between one's physiological sex and the gender identity that is one's basic sense of self as a man or a woman is known as gender identity disorder. In general, the conditions of physiological men having female gender identity and physiological women having male gender identity are called male-to-female and female-to-male gender identity disorder, respectively. Although the precise pathogenesis of gender identity disorder remains unclear, the prevalence of gender identity disorder is quite high, with the rates calculated for male-to-female to be 1:25,000 and female-to-male to be 1:12,000 in Hokkaido, Japan. The diagnosis and treatment of gender identity disorder in Japan are based on the Diagnostic and Therapeutic Guidelines for Patients with Gender Identity Disorder, 4th edition. Although gender identity disorder was previously thought to be a psychiatric condition, it is extremely difficult to assign gender identity to physiological sex by psychiatric and psychological treatments. To adapt the figure of the body to the native gender identity, physical treatments such as administration of cross-sex steroids and sex reassignment surgery are considered. However, there are very few institutions that routinely carry out sex reassignment surgery in Japan, even though it is mandatory for changing sex on the census register at the present time. Sex reassignment surgery for male-to-female and female-to-male patients includes orchiectomy, penectomy, clitoroplasty, vaginoplasty and vulvoplasty, and hysterectomy, ovariectomy, metoidioplasty and phalloplasty, respectively. To provide accurate information about physical treatment for patients with gender identity disorder, even urologists who are not actively involved in the diagnosis and treatment of gender identity disorder should understand the fundamental aspects and contemporary problems of gender identity disorder. © 2012 The Japanese Urological Association.

The number of adults with congenital heart disease (CHD) is increasing rapidly, but care programs have not been fully established in Japan. Questionnaires regarding current status and resources of outpatient and in-hospital services, and management of pregnancy in patients with adult CHD (ACHD) were sent to 1,033 training hospitals for board-certified cardiologists. Useful replies were obtained from 458 hospitals (44%). In 417 hospitals (91%), at least 1 patient was followed in the outpatient clinic; however, only 14 hospitals (3%) had specialized outpatient clinics; 354 hospitals (77%) had in-hospital patients, but only 6 hospitals (2%) admitted >50 patients per year. Surgery for ACHD was performed in 232 hospitals (51%), but in 135 of these (58%), the number of operations was <5 per year. Pregnant women with CHD were managed in 157 hospitals (34%), although only 3 hospitals (2%) managed >10 cases per year. In most hospitals in Japan, a limited number of ACHD patients have been followed up and specialized multi-disciplinary facilities for ACHD need to be established.

First, we analyzed the common parts in five standardized nursing terminology sets: the Japan Nursing Practice Standard Master (JNPSM) that includes the names of nursing activities and is built by the Medical Information Center Development Center (MEDIS-DC); the labels of the Japan Classification of Nursing Practice (JCNP), built by the term advisory committee in the Japan Academy of Nursing Science; the labels of the International Classification for Nursing Practice (ICNP) translated to Japanese; the labels, domain names, and class names of the North American Nursing Diagnosis Association (NANDA) Nursing Diagnoses 2003-2004 translated to Japanese; and the terms included in the labels of Nursing Interventions Classification (NIC) translated to Japanese. Then we compared them with terms in a thesaurus dictionary, the Bunrui Goihyo, that contains general Japanese words and is built by the National Institute for Japanese Language. 1) the level of interchangeability between four standardized nursing terminology sets is quite low; 2) abbreviations and katakana words are frequently used to express nursing activities; 3) general Japanese words are usually used to express the status or situation of patients.

Psychohistorical Hypotheses on Japan's History of Hostility Towards China.

Wang, Bo; Rudmin, Floyd

2016-01-01

The accelerating tensions and military posturing between Japan and China have created a serious crisis with a danger of a catastrophic war. The purpose of this paper is to summarize the events of the current crisis, and to put it in the context of Japan's long history of hostility to China and repeated attempts at conquest. The historical record shows that Japan has attacked China at least seven times, even though China has never attacked Japan. The irrationality of Japan's behavior is demonstrated by the repetition of this hostile behavior despite the enormous human and economic costs that Japan has suffered because of it. The irrationality of Japan's militarism suggests that psychological explanations may be required to understand this phenomenon. Several hypotheses are proposed, including 1) projected paranoid aggression, 2) collective Zeigarnik compulsion, 3) perceived weakness exciting aggression, 4) national inferiority feelings, 5) cultural narcissism, and 6) Oedipal-like hatred of a parent culture.

To investigate the relationship between personal experience of the Great East Japan Earthquake and various disease types among nursery school children. We conducted a nationwide survey of nursery school children born between 2 April 2006 and 1 April 2007. Nursery school teachers completed questionnaires if they agreed to join the study. Questionnaire items for children consisted of their birth year and month, sex, any history of moving into or out of the current nursery school, presence of diseases diagnosed by a physician at the age of 66-78 months and type of disaster experience. The survey was conducted from September 2012 to December 2012. Japan, nationwide. A total of 60 270 nursery school children were included in the analysis, 840 of whom experienced the disaster on 11 March 2011. The health status of children 1.5 years after the disaster based on nursery school records. Experiencing the disaster significantly affected the prevalence of overall and individual diseases. Furthermore, there was a difference in disease prevalence between boys and girls. In boys, experiencing the tsunami (OR 2.53, 95% CI 1.22 to 5.24) and living in an evacuation centre (OR 2.92, 95% CI 1.46 to 5.83) were remarkably associated with a higher prevalence of atopic dermatitis, but these trends were not observed among girls. Instead, the home being destroyed (OR 3.50, 95% CI 2.02 to 6.07) and moving house (OR 4.19, 95% CI 2.01 to 8.71) were positively associated with a higher prevalence of asthma among girls. Our study indicates that experiencing the disaster may have affected the health status of nursery school children at least up to 1.5 years after the disaster. Continuous monitoring of the health status of children is necessary to develop strategic plans for child health.

Providing palliative care in Japan is one of the most important health issues. Understanding palliative care delivery systems of other countries is useful when developing and modifying palliative care systems worldwide. This review summarizes the current status of palliative care in Japan, focusing on the structure and process development. Palliative care units and hospital palliative care consultation teams are the two main specialized palliative care services in Japan. The number of palliative care units is 215 (involved in 8.4% of all cancer deaths), and there are approximately 500 hospital palliative care teams. Conversely, specialized home care services are one of the most undeveloped areas in Japan. However, the government has been trying to develop more efficient home care services through modifying laws, healthcare systems, and multiple educational and cooperative projects. The numbers of palliative care specialists are increasing across all disciplines: cancer pain nurses (1365), palliative care nurses (1100), palliative care physicians (646), and palliative care pharmacists (238). Postgraduate education for physicians is performed via the special nationwide efforts of the Palliative care Emphasis program on symptom management and Assessment for Continuous medical Education (PEACE) project - a 2-day program adopting a trainer-trainee strategy. Over 30,000 physicians have participated in the PEACE program. A total of 1298 and 544 physicians have completed a trainer course for palliative medicine and psycho-oncology, respectively. Multiple structure and process evaluation, bereaved family surveys in palliative care units, and patient and family evaluation in the regional palliative care program indicate many improvements. Palliative care in Japan has progressed rapidly, and the Cancer Control Act has played a very important role in developing palliative medicine. Challenges include developing a structure for palliative care in the community or regional

This perspective piece gives an overview of the current situation of yoga therapy in Japan today. Traditional yoga in Japan suffered a serious setback in 1995 with a nerve gas terrorist attack on the Tokyo subway, which was carried out by a cult that recruited members through yoga classes. But with the increase in popularity with modern forms of yoga such as Iyengar yoga, Ashtanga yoga and hot yoga in the West, the general public in Japan today is forgetting its aversion to yoga and considers it to be something that can contribute to good health. In 2012, the Japan Yoga Therapy Society (JYTS) conducted a study on adverse events in yoga classes throughout Japan with the University of Kyushu School of Medicine, with support from the Ministry of Health, Labour and Welfare. This study indicated that more than half of people attending yoga classes have some form of chronic illness, with 42.3% receiving outpatient care. This survey was the beginning of growing interest from both the government and universities in yoga therapy. JYTS is beginning to make inroads into bringing yoga therapy into cancer and palliative care, senior citizen homes, alcohol and drug addiction rehabilitation, cardiovascular rehabilitation, and research on trauma and schizophrenia. While there are still limited opportunities for yoga therapists to work in mainstream healthcare services, there is growing interest among medical professionals in both physical and mental health.

2015-01-01

Despite recent advances in care, stroke remains a life-threatening disease. Little is known about current hospital mortality with stroke and how it varies by hospital in a national clinical setting in Japan. Using the Diagnosis Procedure Combination database (a national inpatient database in Japan), we identified patients aged ≥ 20 years who were admitted to the hospital with a primary diagnosis of stroke within 3 days of stroke onset from April 2012 to March 2013. We constructed a multivariable logistic regression model to predict in-hospital death for each patient with patient-level factors, including age, sex, type of stroke, Japan Coma Scale, and modified Rankin Scale. We defined risk-standardized mortality ratio as the ratio of the actual number of in-hospital deaths to the expected number of such deaths for each hospital. A hospital-level multivariable linear regression was modeled to analyze the association between risk-standardized mortality ratio and hospital-level factors. We performed a patient-level Cox regression analysis to examine the association of in-hospital death with both patient-level and hospital-level factors. Of 176,753 eligible patients from 894 hospitals, overall in-hospital mortality was 10.8%. The risk-standardized mortality ratio for stroke varied widely among the hospitals; the proportions of hospitals with risk-standardized mortality ratio categories of ≤ 0.50, 0.51-1.00, 1.01-1.50, 1.51-2.00, and >2.00 were 3.9%, 47.9%, 41.4%, 5.2%, and 1.5%, respectively. Academic status, presence of a stroke care unit, higher hospital volume and availability of endovascular therapy had a significantly lower risk-standardized mortality ratio; distance from the patient's residence to the hospital was not associated with the risk-standardized mortality ratio. Our results suggest that stroke-ready hospitals play an important role in improving stroke mortality in Japan.

Towards a causal model of childbearing and abortion attitudes in contemporary Japan.

PubMed

Ogawa, N; Hodge, R W

1983-01-01

Described in this paper is the rationale and thinking behind the development of a causal model of childbearing and abortion attitudes in contemporary Japan. This effort represents one of the 1st attempts to build a multiple equation, micro-level model of fertility and fertility related behavior and attitudes in Japan. The results are almost wholely consistent with received demographic theory. Japan has now reached the last stage of her demographic transition and the results are consistent with the view that social and economic differentials in fertility are gradually eroded over the course of the transition. There are still statistically significant residues of these differentials in contemporary Japan, but they are at best modest in scope. Fertility in modern Japan is largely a matter of age and personal desires. Even abortion, which was so instrumental in moving Japan through the middle stages of her demographic transition in the immediate postwar period, exhibits only weak relationships with the social and economic position of women; attitudes about abortion are even more weakly linked to the social order. In sum, as of 1981, the process of family formation appears to have evolved to the point where it is largely homogeneous with respect to social and economic status. The differentials which remain are the expected ones, but their magnitude is not overwhelming and the force of social location is at most only a modest constraint on fertility behavior and fertility related beliefs and attitudes. This is the exact scenario one expects to find in a nation which is at the final stage of its demographic transition. The present analysis is current and cross-sectional. It is largely exploratory and as such, represents one of the very 1st efforts to develop a structural equation model of individual fertility behavior in Japan. The findings are based on the analysis of the data gathered in Japan in connection with ESCAP Study on the Relationship Between Fertility Behavior

To compare anamnestic antibody responses of dogs and cats with current versus out-of-date vaccination status. Cross-sectional study. 74 dogs and 33 cats. Serum samples were obtained from dogs and cats that had been exposed to rabies and brought to a veterinarian for proactive serologic monitoring or that had been brought to a veterinarian for booster rabies vaccination. Blood samples were collected on the day of initial evaluation (day 0) and then again 5 to 15 days later. On day 0, a rabies vaccine was administered according to label recommendations. Paired serum samples were analyzed for antirabies antibodies by means of a rapid fluorescent focus inhibition test. All animals had an antirabies antibody titer ≥ 0.5 IU/mL 5 to 15 days after booster vaccination. Dogs with an out-of-date vaccination status had a higher median increase in titer, higher median fold increase in titer, and higher median titer following booster vaccination, compared with dogs with current vaccination status. Most (26/33) cats, regardless of rabies vaccination status, had a titer ≥ 12 IU/mL 5 to 15 days after booster vaccination. Results indicated that dogs with out-of-date vaccination status were not inferior in their antibody response following booster rabies vaccination, compared with dogs with current vaccination status. Findings supported immediate booster vaccination followed by observation for 45 days of dogs and cats with an out-of-date vaccination status that are exposed to rabies, as is the current practice for dogs and cats with current vaccination status.

Generic Medicine Pricing Policies in Europe: Current Status and Impact

2010-01-01

Generic medicine pricing is an area of national responsibility of European Union countries. This article aims to present the current status and impact of generic medicine pricing policies in ambulatory care in Europe. The study conducts a literature review of policies relating to free-pricing systems, price-regulated systems, price differentiation, price competition and discounts, and tendering procedures; and a survey of European generic medicine pricing policies. Competition from Indian generic medicine manufacturers, European variation in generic medicine prices and competition between generic medicine manufacturers by discount suggest that the potential savings to health care payers and patients from generic medicines are not fully realized in Europe. One way of attaining these savings may be to move away from competition by discount to competition by price. Free-pricing systems may drive medicine prices downwards under specific conditions. In price-regulated systems, regulation may lower prices of originator and generic medicines, but may also remove incentives for additional price reductions beyond those imposed by regulation. To date, little is known about the current status and impact of tendering procedures for medicines in ambulatory care. In conclusion, the European experience suggests that there is not a single approach towards developing generic medicine pricing policies in Europe. PMID:27713264

Objectives: Prevalence of life-style disease has increased dramatically in evacuees due to the Great East Japan Earthquake. One reason may be that physical activity level decreased from life environment changes due to evacuation. However, associations between evacuation condition and habitual physical activity have not been studied. We examined this association in Fukushima residents who participated in the Fukushima Health Management Survey. Methods: In this study, 37,843 evacuees from 13 municipal evacuation zones from the nuclear-power accident caused by the Great East Japan Earthquake, born before April 1, 1995, were included in the analysis. Evacuation condition was defined by disaster living place (13 zones), evacuation place (inside or outside the prefecture), and current living status (evacuation shelter or temporary housing, rental housing/ apartment, and relative's home or own home). Habitual physical activity was defined from self-administered questionnaires as participants who responded "almost every day" and "2-4 times/week" of regular exercise. In the analysis, habitual physical activity prevalence was aggregated by gender and variables (living place in the disaster, evacuation place, and current living status). Prevalence was adjusted for age, disaster living place, evacuation place, and current living status by standard analysis of covariance methods. Results: Adjusted prevalences of habitual physical activity were: men, 27.9-46.5%; women, 27.0-43.7% in each disaster living place. The differences were 18.6% point in men and 16.7% point in women. For evacuation place, physical activity outside the prefecture for men (37.7%) and inside the prefecture for women (32.1%) were higher, but those differences were only 2.2% point and 1.8% point in men and women, respectively. For current living status, physical activity of those in rental housing/ apartment was the lowest; evacuation shelter or temporary housing was the highest in both genders (men: 38

Social Environment and Control Status of Companion Animal-Borne Zoonoses in Japan

PubMed Central

2012-01-01

Simple Summary The risk of companion animal-borne zoonoses has been rising in Japan with the tendency for increasing number of households to ever-growing numbers and varieties of animals as pets. In response, the Japanese government has implemented measures for the domestic and border control of zoonoses. However, it is impossible to determine whether these measures have adequately controlled the transmission of companion animal-borne zoonoses, due to a lack of (i) direct evidence linking companion animal involvement in disease and (ii) understanding of current trends in disease outbreak. Active surveillance should be conducted on a national level to collect the data necessary to make this determination and identify these trends. Abstract Changing social and environmental factors have been the cause of an increase in the number and variety of animals are being imported into Japan. Moreover, the number of Japanese households are keeping companion animals has also risen. These factors, along with the high density of the Japanese population and the low percentage of registered dogs, have increased the risk of animal-to-human transmission of zoonoses. To control zoonosis outbreaks, the Japanese government has implemented a three-stage approach for the border control of zoonoses and has stipulated the monitoring and reporting of eight companion animal-borne zoonoses under the Rabies Prevention Law and the Infectious Diseases Control Law. The fact that no case of human and animal rabies has been reported over the past 50 years indicates that these measures are highly effective in preventing rabies transmission. Although it is known that the total number of possible companion animal-borne zoonosis outbreaks decreased between 2005 and 2009 when compared with numbers between 2001 and 2004, the number of zoonosis cases that can be attributed to transmission by companion animals remains unclear. Active surveillance should be conducted on a national level to collect the data

The burden of dementia in Japan is large and growing. With the world's fastest aging population, it is estimated that one in five elderly people will be living with dementia in Japan by 2025. The most common form of dementia is Alzheimer's disease (AD), accounting for around two-thirds of dementia cases. A systematic review was conducted to examine the epidemiology and associated burden of AD in Japan and to identify how AD is diagnosed and managed in Japan. English and Japanese language databases were searched for articles published between January 2000 and November 2015. Relevant Japanese sources, clinical practice guideline registers, and reference lists were also searched. Systematic reviews and cohort and case-control studies were eligible for inclusion, with a total of 60 studies included. The most recent national survey conducted in six regions of Japan reported the mean prevalence of dementia in people aged ≥65 years to be 15.75% (95% CI: 12.4, 22.2%), which is much higher than the previous estimated rate of 10% in 2010. AD was confirmed as the predominant type of dementia, accounting for 65.8% of all cases. Advancing age and low education were the most consistently reported risk factors for AD dementia. Japanese guidelines for the management of dementia were released in 2010 providing specific guidance for AD about clinical signs, image findings, biochemical markers, and treatment approaches. Pharmacotherapies and non-pharmacotherapies to relieve cognitive symptoms were introduced, as were recommendations to achieve better patient care. No studies reporting treatment patterns were identified. Due to population aging and growing awareness of AD in Japan, health care expenditure and associated burden are expected to soar. This review highlights the importance of early detection, diagnosis, and treatment of AD as strategies to minimize the impact of AD on society in Japan.

We review the status of marine shellfish ecosystems formed primarily by bivalves in Australia, including: identifying ecosystem-forming species, assessing their historical and current extent, causes for decline and past and present management. Fourteen species of bivalves were identified as developing complex, three-dimensional reef or bed ecosystems in intertidal and subtidal areas across tropical, subtropical and temperate Australia. A dramatic decline in the extent and condition of Australia's two most common shellfish ecosystems, developed by Saccostrea glomerata and Ostrea angasi oysters, occurred during the mid-1800s to early 1900s in concurrence with extensive harvesting for food and lime production, ecosystem modification, disease outbreaks and a decline in water quality. Out of 118 historical locations containing O. angasi-developed ecosystems, only one location still contains the ecosystem whilst only six locations are known to still contain S. glomerata-developed ecosystems out of 60 historical locations. Ecosystems developed by the introduced oyster Crasostrea gigas are likely to be increasing in extent, whilst data on the remaining 11 ecosystem-forming species are limited, preventing a detailed assessment of their current ecosystem-forming status. Our analysis identifies that current knowledge on extent, physical characteristics, biodiversity and ecosystem services of Australian shellfish ecosystems is extremely limited. Despite the limited information on shellfish ecosystems, a number of restoration projects have recently been initiated across Australia and we propose a number of existing government policies and conservation mechanisms, if enacted, would readily serve to support the future conservation and recovery of Australia's shellfish ecosystems.

The Global Positioning System (GPS), developed by the Department of Defense is quickly revolutionizing the architecture of future spacecraft and spacecraft systems. Significant savings in spacecraft life cycle cost, in power, and in mass can be realized by exploiting GPS technology in spaceborne vehicles. These savings are realized because GPS is a systems sensor--it combines the ability to sense space vehicle trajectory, attitude, time, and relative ranging between vehicles into one package. As a result, a reduced spacecraft sensor complement can be employed and significant reductions in space vehicle operations cost can be realized through enhanced on-board autonomy. This paper provides an overview of the current status of spaceborne GPS, a description of spaceborne GPS receivers available now and in the near future, a description of the 1997-2000 GPS flight experiments, and the spaceborne GPS team's vision for the future.

The major aspects of the C2, C3 and C4 elemental carbon clusters are surveyed. For C2, a brief analysis of its current status is presented. Regarding C3, the most recent results obtained in our group are reviewed with emphasis on modelling its potential energy surface which is particularly complicated due to the presence of multiple conical intersections. As for C4, the most stable isomeric forms of both triplet and singlet spin states and their possible interconversion pathways are examined afresh by means of accurate ab initio calculations. The main strategies for modelling the ground triplet C4 potential are also discussed. Starting from a truncated cluster expansion and a previously reported DMBE form for C3, an approximate four-body term is calibrated from the ab initio energies. The final six-dimensional global DMBE form so obtained reproduces all known topographical aspects while providing an accurate description of the C4 linear-rhombic isomerization pathway. It is therefore commended for both spectroscopic and reaction dynamics studies. This article is part of the theme issue `Modern theoretical chemistry'.

Infection of Helicobacter pylori mainly occurs in childhood. In Japan, incidence of gastric cancer is still high in the senior citizen population, but little is known about the current H. pylori infection status among children or their family members. As a population-based study, the prevalence of H. pylori infection and change in infection status over a 1-year interval in children were determined. Family members of some participants were also invited to participate in the study to determine their infection status. All children of specific ages attending 16 schools in Sasayama, Hyogo Prefecture, were invited to participate. H. pylori infection was determined by the stool antigen test and diagnosis confirmed by polymerase chain reaction and the urea breath test. Helicobacter pylori prevalence was 1.9% among 689 children aged 0-8 years in 2010 and 1.8% among 835 children aged 0-11 in 2011. No feco-conversion was observed in 430 children aged 0-8 years (170 were aged 0-4 years) who provided follow-up stool samples after 1 year. The prevalence of infection was 6% (2 of 33) and 38% (6 of 16) in mothers of negative and positive probands (p = .04), respectively, and 12% (3 of 25) and 50% (8 of 16) (p = .01), respectively, in fathers. Helicobacter pylori prevalence in Japanese children is approximately 1.8%, which is much lower than that reported in Japanese adults. New infection may be rare. Parent-to-child infection is thought to be the main infection route of the infrequent infection for children in Japan. © 2014 John Wiley & Sons Ltd.

Okinawa: an exception to the social gradient of life expectancy in Japan.

PubMed

Cockerham, W C; Yamori, Y

2001-01-01

This paper examines why the social gradient of life expectancy does not apply in Japan when Okinawa is considered. The social gradient thesis links differences in longevity to social rank, with people and populations in higher status hierarchical positions having lower mortality and longer life expectancies than those beneath them in the social scale. Japan has been cited as a major example of this thesis in that Japanese life expectancy improved dramatically as Japan rose to the top echelon of nations in economic rank in the late 20th century. Thus it follows that Japan's most affluent and leading prefectures should be the major catalysts behind the nation's rise in life expectancy as well to the number one position in the world. However, this is not the case as life expectancy in Okinawa, Japan's poorest prefecture, exceeds that of Japan as a whole. We find that the social gradient of life expectancy does not apply at the prefectural level and question its validity for geographical areas. We suggest that healthy lifestyles, especially diet and the social support of family and friends, are more important than sense of hierarchy for longevity in Okinawa.

DNA Methylation in Osteoarthritis: Current Status and Therapeutic Implications

Miranda-Duarte, Antonio

2018-01-01

Background: Primary Osteoarthritis (OA) is a multifactorial disease in which genetic factors are strongly associated with its development; however, recently it has been observed that epigenetic modifications are also involved in the pathogenesis of OA. DNA methylation is related to gene silencing, and several studies have investigated its role in the loci of different pathways or molecules associated to OA. Objective: This review is focused on the current status of DNA methylation studies related to OA pathogenesis. Method: A review of the literature was conducted on searching in PUBMED for original papers on DNA methylation in OA. Conclusion: The DNA methylation research of loci related to OA pathogenesis has shown a correlation between methylation and gene repression; however, there are some exceptions to this rule. Recently, the development of genome-wide methylation and genome-wide hydroxymethylation profiles has demonstrated that several genes previously associated with OA can have changes in their methylation status, favoring the development of the disease, and these have even shown the role of other epigenetic markers.

Twenty-nine urban inhabitants participated in a half-day climatotherapy programme at the moderate mountain area and lowland area in the northwest part of the main island of Japan. The current study was aimed to investigate physically and mentally the objective and subjective influence of our short programme, which was a prospective pilot study of single intervention. Blood pressure was significantly descended during terrain cure at the uphill mountain path and returned after fresh-air rest cure, while there was no significant change throughout the programme at lowland flat path. Heart rate was significantly ascended and descended at both area, and more clearly changed at the mountain path. Profile of Mood Status brief form Japanese version administered before and after our half-day programme. Age adjusted T score of negative subscales, `tension-anxiety', `depression', `anger-hostility', `fatigue' and `confusion' were significantly lower after climatotherapy at both sites. Whereas, there was no significant change concerning `vigour' score. This short-version climatotherapy programme has been designed for people without enough time for long stay at health resort. It turned out our half-day climatotherapy programme contribute to mood status improvement. In addition, repeated practice of our short-version programme including endurance exercise with cool body shell using uphill path can be expected that blood pressure will go toward the normal range and heart rate will decrease both in usual time and during exercise. Therefore, health benefits can be expected of this climatotherapy programme.

The Extramural Mycology Program of the National Institutes of Health (NIH), National Institute of Allergy and Infectious Diseases (NIAID) has organized and implemented a five workshop series in medical mycology during a critical period in the evolution of contemporary medical mycology (1992 to 2000; http://www.niaid.nih.gov/research/dmid.htm). The goals of the workshop series were to: initiate interactions; build collaborations; identify research needs; turn needs into opportunities; stimulate molecular research in medical mycology; and summarize recommendations emerging from the workshop proceedings. A recurring recommendation in the series was to foster communications within and beyond the field of medical mycology. US-Japan interactions were noted as one specific example of potential information exchange for mutual benefit. The first formal action directed at this recommendation was the workshop Emergence and Recognition of Fungal Diseases convened under the auspices of the US-Japan Cooperative Medical Science Program (USJCMSP; http://www.niaid. nih.gov/dmid/us%5Fjapan/default.htm) in Bethesda, Maryland USA on 30 June 1999 (D.M. Dixon & T. Matsumoto, co-chairs). A major goal of the workshop was to present contemporary medical mycology to the Joint Committee of the USJCMSP through representative research presentations in order to make the Committee aware of current status in the field, and the potential for scientific interactions. The second formal action is the workshop, under the auspices of the Japanese Society for Medical Mycology Medical Perspectives of Fungal Genome Studies scheduled for 28 November 2000 in Tokyo, Japan (T. Matsumoto & D.M. Dixon, co-chairs). The NIAID Mycology Workshop series recommended interactions between the following groups: academic and pharmaceutical; medical and molecular (model systems); medical and plant pathogens; basic and clinical; mycologists and immunologists. The first two US-Japan workshops can be viewed as consistent

Parasitic infection profile in China has been changed greatly with the rapid economic development in China since the 1980s, such as the tremendous decreased infection rate of the soil-borne helminthiasis, the elimination of filariasis, the control of malaria, and the initiation to eradicate malaria in 2020. Some food-borne parasitic infections have increased such as Clonorchiasis, Cysticercosis, and Echinococcosis, probably because of the increased chances of eating out. This trend directly affected the status of Human Parasitology teaching in medical universities, such as the shorten length of this course, re-adjusted contents structure and teaching manners, even the change of the name of this course. In this paper, we analyzed the current status and challenges of Human Parasitology teaching in medical universities, and discussed the requisite contents and manners in course delivery and measures to improve the quality of Human Parasitology teaching in China.

There were some think tank businesses in Japan before the war. South Manchuria Railway Company established its Research Department for the purpose of getting power to control Manchuria as a colony, and got the good results. Think tank business was flourishing three times after the war. This business attracts much attention when the social and economic paradigm is going to change. Among the key large-scale think tanks in Japan, Nomura Research Institute, Ltd. (NRI) was the first to enhance the system functions by the merger, and posted think tank function up in the SI business. Mitsubishi Research Institute, Inc. (MRI) intends to be an orthodox think tank, and established an advanced research institute and the laboratory for R&D. Daiwa Institute of Research, Ltd. (DIR) focuses on economic forecast by using system. Fuji Research Institute. Corp. (FUJI RIC) focuses on survey and policy proposing in macro-economics, and analyzing technology. The Japan Research Institute, Ltd. (JRI) focuses on regional development, and R&D in advanced technology.

Since the first somatic cell cloned calves were born in Japan in 1998, more than 500 cloned cattle have been produced by somatic cell nuclear transfer and many studies concerning cloned cattle and their offspring have been conducted in this country. However, most of the results have been published in Japanese; thus, the data produced in this country is not well utilized by researchers throughout the world. This article reviews the 65 reports produced by Japanese researchers (62 written in Japanese and 3 written in English), which employed 171 clones and 32 offspring, and categorizes them according to the following 7 categories: (1) genetic similarities and muzzle prints, (2) hematology and clinical chemistry findings, (3) pathology, (4) growth performance, (5) reproductive performance, (6) meat production performance and (7) milk production performance. No remarkable differences in health status or reproductive performance were found among conventionally bred cattle, somatic cell cloned cattle surviving to adulthood and offspring of somatic cell cloned cattle. Similarities in growth performance and meat quality were observed between nuclear donor cattle and their clones. The growth curves of the offspring resembled those of their full siblings.

Medical marijuana is currently a controversial issue in medicine. There are strong pro and con opinions but relatively little scientific data on which to base medical decisions. The unfortunate scheduling of marijuana in class I has limited research and only serves to fuel the controversy. This article will review the history of laws to regulate drugs in the United States in the 20th century to provide context for the current status of medical marijuana. It will include the rationale for opposing medical marijuana laws and the problem of the Schedule I inclusion of marijuana as well as other drugs. It will examine the problems associated with smoking raw marijuana and review other routes of administration. Finally, it examines the inadvisability of medicine's promotion of smoked marijuana.

Menstrual status, both past and current, has been established as an important determinant of bone mineral density (BMD) in young exercising women. However, little is known regarding the association between the cumulative effect of menstrual status and indices of bone health beyond BMD, such as bone geometry and estimated bone strength. This study explores the association between cumulative menstrual status and indices of bone health assessed using dual-energy x-ray absorptiometry (DXA), including femoral neck geometry and strength and areal BMD (aBMD), in exercising women. 101 exercising women (22.0±0.4years, BMI 21.0±0.2kg/m(2), 520±40min/week of self-reported exercise) participated in this cross-sectional study. Women were divided into three groups as follows based on their self-reported current and past menstrual status: 1) current and past regular menstrual cycles (C+P-R) (n=23), 2) current and past irregular menstrual cycles (C+P-IR) (n=56), 3) and current or past irregular cycles (C/P-RIR) (n=22). Current menstrual status was confirmed using daily urinary metabolites of reproductive hormones. DXA was used to assess estimates of femoral neck geometry and strength from hip strength analysis (HSA), aBMD, and body composition. Cross-sectional moment of inertia (CSMI), cross-sectional area (CSA), strength index (SI), diameter, and section modulus (Z) were calculated at the femoral neck. Low CSMI, CSA, SI, diameter, and Z were operationally defined as values below the median. Areal BMD (g/cm(2)) and Z-scores were determined at the lumbar spine, femoral neck, and total hip. Low BMD was defined as a Z-score<-1.0. Chi-square tests and multivariable logistic regression were performed to compare the prevalence and determine the odds, respectively, of low bone geometry, strength, and aBMD among groups. Cumulative menstrual status was identified as a significant predictor of low femoral neck CSMI (p=0.005), CSA (p≤0.024), and diameter (p=0.042) after controlling for

Histone deacetylase (HDAC) inhibitors are a new group of anticancer agents that have a potential role in the regulation of gene expression, induction of cell death, apoptosis and cell cycle arrest of cancer cells by altering the acetylation status of chromatin and other non-histone proteins. In clinical trials, HDAC inhibitors have demonstrated promising antitumour activity as monotherapy in cutaneous T-cell lymphoma and other haematological malignancies. In solid tumours, several HDAC inhibitors have been shown to be efficacious as single agents; however, results of most clinical trials were in favour of using HDAC inhibitors either prior to the initiation of chemotherapy or in combination with other treatments. Currently, the molecular basis of response to HDAC inhibitors in patients is not fully understood. In this review, we summarize the current status of HDAC inhibitors, as single agents or in combination with other agents in different phases of clinical trials. In most of the clinical trials, HDAC inhibitors were tolerable and exerted biological or antitumor activity. HDAC inhibitors have been studied in phase I, II and III clinical trials with variable efficacy. The combination of HDAC inhibitors with other anticancer agents including epigenetic or chemotherapeutic agents demonstrated favourable clinical outcome.

Bauer, Frank H.; Hartman, Kate; Lightsey, E. Glenn

1998-01-01

The Global Positioning System (GPS), developed by the Department of Defense, is quickly revolutionizing the architecture of future spacecraft and spacecraft systems. Significant savings in spacecraft life cycle cost, in power, and in mass can be realized by exploiting Global Positioning System (GPS) technology in spaceborne vehicles. These savings are realized because GPS is a systems sensor-it combines the ability to sense space vehicle trajectory, attitude, time, and relative ranging between vehicles into one package. As a result, a reduced spacecraft sensor complement can be employed on spacecraft and significant reductions in space vehicle operations cost can be realized through enhanced on- board autonomy. This paper provides an overview of the current status of spaceborne GPS, a description of spaceborne GPS receivers available now and in the near future, a description of the 1997-1999 GPS flight experiments and the spaceborne GPS team's vision for the future.

Risk models of cardiac valve surgery using a large database are useful for improving surgical quality. In order to obtain accurate, high-quality assessments of surgical outcome, each geographic area should maintain its own database. The study aim was to collect Japanese data and to prepare a risk stratification of cardiac valve procedures, using the Japan Adult Cardiovascular Surgery Database (JACVSD). A total of 6562 valve procedure records from 97 participating sites throughout Japan was analyzed, using a data entry form with 255 variables that was sent to the JACVSD office from a web-based data collection system. The statistical model was constructed using multiple logistic regression. Model discrimination was tested using the area under the receiver operating characteristic curve (C-index). The model calibration was tested using the Hosmer-Lemeshow (H-L) test. Among 6562 operated cases, 15% had diabetes mellitus, 5% were urgent, and 12% involved preoperative renal failure. The observed 30-day and operative mortality rates were 2.9% and 4.0%, respectively. Significant variables with high odds ratios included emergent or salvage status (3.83), reoperation (3.43), and left ventricular dysfunction (3.01). The H-L test and C-index values for 30-day mortality were satisfactory (0.44 and 0.80, respectively). The results obtained in Japan were at least as good as those reported elsewhere. The performance of this risk model also matched that of the STS National Adult Cardiac Database and the European Society Database.

There is increasing patient and surgeon interest in robotic-assisted surgery, particularly with the proliferation of da Vinci surgical systems (Intuitive Surgical, Sunnyvale, CA, USA) throughout the world. There is much debate over the usefulness and cost-effectiveness of these systems. The currently available robotic surgical technology is described. Published data relating to the da Vinci system are reviewed and the current status of surgical robotics within Australia and New Zealand is assessed. The first da Vinci system in Australia and New Zealand was installed in 2003. Four systems had been installed by 2006 and seven systems are currently in use. Most of these are based in private hospitals. Technical advantages of this system include 3-D vision, enhanced dexterity and improved ergonomics when compared with standard laparoscopic surgery. Most procedures currently carried out are urological, with cardiac, gynaecological and general surgeons also using this system. The number of patients undergoing robotic-assisted surgery in Australia and New Zealand has increased fivefold in the past 4 years. The most common procedure carried out is robotic-assisted laparoscopic radical prostatectomy. Published data suggest that robotic-assisted surgery is feasible and safe although the installation and recurring costs remain high. There is increasing acceptance of robotic-assisted surgery, especially for urological procedures. The da Vinci surgical system is becoming more widely available in Australia and New Zealand. Other surgical specialties will probably use this technology. Significant costs are associated with robotic technology and it is not yet widely available to public patients.

Prior to the introduction of killed whole cell pertussis vaccine [wP] in the 1940s, whooping cough was a major cause of infant death worldwide. Widespread vaccination of children with this vaccine caused a significant reduction in mortality. However in the 1990s and now more recently, there has been a resurgence of pertussis in several countries even in populations previously vaccinated with an acellular pertussis vaccine [aP]. In this review, we describe the epidemiology of whooping cough, the vast array of virulence factors produced by this pathogen potentially contributing to the resurgence of pertussis even in previously vaccinated populations of infants and children, history of whooping cough prophylaxis, possible mechanisms of immunity, lack of availability of a suitable non-toxic adjuvant capable of inducing both arms of the immune response, and the current status of development of improved vaccines with potential to induce longer-lasting protection, than is currently possible with the wP or aP vaccines, against whooping cough.

The Great East Japan Earthquake and devastating Tsunami hit hard everything on the northeastern coast of Japan. This study aimed to determine socio-psychological factors for "subjective shoulder pain" of the survivors at 2 years evaluated by a self-report questionnaire. Between November 2012 to February 2013, survivors replied to the self-report questionnaire, and 2275 people consented to join this study. Living status was divided into 5 categories (1. same house as before the earthquake (reference group), 2. temporary small house, 3. apartment, 4. house of relatives or acquaintance, 5. new house) and economic hardship was divided into 4 categories (1. normal (reference group), 2. a little bit hard, 3. hard, 4. very hard). Gender, age, body mass index, living areas, smoking and drinking habits, complications of diabetes mellitus and cerebral stroke, working status, and walking time were considered as the confounding factors. Kessler Psychological Distress Scale of ≥10/24 and Athens Insomnia Scale of ≥6/24 points were defined as a presence of psychological distress and sleep disturbance, respectively. We used multiple logistic regression analysis to examine the association of shoulder pain with living environment, economic hardship, psychological distress, and sleep disturbance at 2 years after the earthquake. There were significant differences in the risk of having shoulder pain in those with "apartment" (OR = 1.74, 95% CI = 1.03-2.96), "house of relatives or acquaintance" (OR = 2.98, 95% CI = 1.42-6.25), economic hardship of "hard" (OR = 1.71, 95% CI = 1.08-2.7) and "very hard" (OR = 2.51, 95% CI = 1.47-4.29), and sleep disturbance (OR = 2.96, 95% CI = 2.05-4.27). Living status of "apartment" and "house of relatives or acquaintance", economic hardship of "hard" and "very hard", and "sleep disturbance" were significantly associated with shoulder pain.

2018-01-01

Pain is a pervasive, debilitating disorder that is resistant to long-term pharmacological interventions. Although psychological therapies such as cognitive behavior therapy demonstrate moderate efficacy, many individuals continue to have ongoing difficulties following treatment. There is a current trend to establish complementary and integrative health interventions for chronic pain, for which yoga has been found to have exciting potential. Nevertheless, an important consideration within the field is accessibility to adequate care. Telehealth can be used to provide real-time interactive video conferencing leading to increased access to health care for individuals located remotely or who otherwise have difficulty accessing services, perhaps through issues of mobility or proximity of adequate services. This article assesses the current status and feasibility of implementing tele-yoga for chronic pain. Methodological limitations and recommendations for future research are discussed.

GALS will exploit available beams from the U-400M cyclotron in low energy multi-nucleon transfer reactions to study exotic neutron-rich nuclei located in the "north-east" region of nuclear map. Products from 4.5 to 9 MeV/nucleon heavy-ion collisions, such as 136Xe on 208Pb, are thermalized and neutralized in a high pressure gas cell and subsequently selectively laser re-ionized. In order to choose the best scheme of ion extraction the results of computer simulations of two different systems are presented. The first off- and online experiment will be performed on osmium atoms that is regarded as a most convenient element for producing isotopes with neutron number in the vicinity of the magic N = 126.

Messenger RNA is emerging as a highly versatile biological construct for creation of impactful medicines. mRNA vaccines directed toward infectious disease and cancer are in clinical development with encouraging early reads on tolerability and efficacy. The use of mRNA to direct intense but transient expression of paracrine factors is finding utility in reprogramming progenitor cells for wound healing and cardiac regeneration and for stimulation of antitumor immune responses, at least preclinically as we await clinical results. The use of mRNA for prolonged and repeated expression of proteins and enzymes to treat rare, typically monogenic disease is nearing clinical entry. These uses of mRNA require delivery solutions, and the application of and improvement to existing nanoparticle nucleic acid delivery systems have jump started the pace of development and reenergized the field of particle based nucleic acid delivery. The current status of mRNA delivery is reviewed in this article with an eye toward clinical tractability.

After an effort of nearly a half century the CTBT was approved by the U.N. on September 10, 1996. Out of 185 member nations (at the time), 158 voted in favor, 3 against, and the remaining either abstained or were diplomatically absent. In spite of such an overwhelming support of the international community, the CTBT may well remain on paper. The reason being that one of the opposing nations, India, is considered a "threshold Nuclear Nation" and must approve the treaty to enter into force according to the rules of Conference of Disarmament (CD). India's U.N. representative said that her country would "never sign this unequal treaty, not now, not later." "Unequal" because it does not provide a time table for elimination of the existing nuclear weapons, testing of weapons, etc., which favor nuclear states. This paper will provide details of the above issues and the current status of the CTBT.

The last decade the installation of wind farms around the world is spreading rapidly and wind energy has become a significant factor for promoting sustainable development. The scope of the present study is to indicate the present status of global wind power expansion as well as the current state of the art in the field of wind turbine technology. The RAM (reliability/availability/maintenance) section is also examined and the Levelized Cost of Energy for onshore/ offshore electricity production is presented. Negative consequences that go with the rapid expansion of wind power like accidents, environmental effects, etc. are highlighted. Especially visual impact to the landscape and noise pollution are some factors that provoke social reactions. Moreover, the complicated and long permitted process of a wind power plant, the high capital cost of the investment and the grid instability due to the intermittent nature of wind, are also significant obstacles in the development of the wind energy production. The current trends in the field of research and development of onshore and offshore wind power production are analyzed. Finally the present study is trying to achieve an estimation of where the wind industry targets for the years to come.

Computed tomography myocardial perfusion (CTP) combined with coronary computed tomography angiography (CCTA) may constitute a "1-stop shop" for the noninvasive diagnosis of hemodynamically significant coronary stenosis during a single CT examination. CTP shows high diagnostic performance and provides incremental value over CCTA for the detection of hemodynamically significant coronary stenosis in patients with a high Agatston calcium score or coronary artery stents. Future studies should determine the optimal protocol and clinical value of CTP for guiding revascularization strategy and prognostication. In this article, we review the current status and future perspectives of CTP, focusing on technical considerations, clinical applications, and future research topics.

The Global Ecosystem Dynamics Investigation: Current Status

NASA Astrophysics Data System (ADS)

Dubayah, R.

2016-12-01

Spaceborne lidar has been identified as a key technology by the international ecosystem science community because it enables accurate estimates of canopy structure and biomass, forms the basis for fusion approaches with existing and planned missions, such as the NASA's ICESat2, ECOSTRESS and OCO3 missions, and extends the capabilities of radar missions such as the NASA-ISRO SAR, Tandem-X and the ESA BIOMASS missions. The Global Ecosystem Dynamics Investigation (GEDI) is a space-based lidar instrument scheduled for launch in late 2018. From its vantage point on the International Space Station, GEDI will provide high-resolution observations of forest vertical structure. These data will be used to address three core science questions: What is the aboveground carbon balance of the land surface? What role will the land surface play in mitigating atmospheric CO2 in the coming decades? How does ecosystem structure affect habitat quality and biodiversity? GEDI informs these science questions by making billions of lidar waveform observations per year. These canopy measurements are then used to estimate biomass and in fusion with radar and other remote sensing data to quantify changes in biomass resulting from disturbance and recovery. GEDI further marries ecosystem structure from lidar with ecosystem and habitat modeling to evaluate the impact of changes in land use and climate on carbon sequestration and biodiversity. In this talk we present an overview of the GEDI mission and its current implementation status. We first review its major science objectives and planned data sets. We then summarize GEDI algorithms and our approach to calibration and validation. Lastly, we provide the status of the instrument hardware build, as well as expected technical performance details.

Although it is suggested that breastfeeding is protective against obesity in children, the evidence remains inconclusive because of possible residual confounding by socioeconomic status or children's lifestyle factors. Most of the participants in the previous studies were children in Western developed countries, so studies in a different context are awaited. To examine the associations of breastfeeding with overweight and obesity among schoolchildren in Japan, with adjustment for the potential confounders. Secondary data analyses of a nationwide longitudinal survey ongoing since 2001, with results collected from 2001 to 2009. All over Japan. A total of 43,367 singleton children who were born after 37 gestational weeks and had information on their feeding during infancy. Five mutually exclusive infant feeding practice categories. Underweight, normal weight (referent group), overweight, and obesity at 7 and 8 years of age defined by using international cutoff points of body mass index by sex and age. In multinomial logistic regression models with adjustment for children's factors (sex, television viewing time, and computer game playing time) and maternal factors (educational attainment, smoking status, and working status), exclusive breastfeeding at 6 to 7 months of age was associated with decreased risk of overweight and obesity compared with formula feeding. The adjusted odds ratios were 0.85 (95% CI, 0.69-1.05) and 0.55 (95% CI, 0.39-0.78) for overweight and obesity, respectively, at 7 years of age. Similar results were observed at 8 years of age. Breastfeeding is associated with decreased risk of overweight and obesity among schoolchildren in Japan. Therefore, it would be better to encourage breastfeeding even in developed countries.

The electron cyclotron (EC) heating and current drive (H&CD) system developed for the ITER is made of 12 sets of high-voltage power supplies feeding 24 gyrotrons connected through 24 transmission lines (TL), to five launchers, four located in upper ports and one at the equatorial level. Nearly all procurements are in-kind, following general ITER philosophy, and will come from Europe, India, Japan, Russia and the USA. The full system is designed to couple to the plasma 20 MW among the 24 MW generated power, at the frequency of 170 GHz, for various physics applications such as plasma start-up, central H&CD and magnetohydrodynamic (MHD) activity control. The design takes present day technology and extends toward high-power continuous operation, which represents a large step forward as compared to the present state of the art. The ITER EC system will be a stepping stone to future EC systems for DEMO and beyond.

Supernova Relic Neutrino (SRN) has not been observed yet because of its low event rate and high background. By adding gadolinium into water Cherenkov detector, inverse beta decay will have two signals, the prompt one is positron signal and the delayed one is a ~8 MeV gamma cascade from neutron capture on gadolinium. By this way, background for SRN can be largely reduced by detecting prompt and delayed signals coincidently, and Super-K will also have the ability to distinguish neutrino and anti-neutrino. SK-Gd is a R&D project proposed to dissolve gadolinium into Super-K. As a part of it, EGADS, a 200 ton water Cherenkov detector was built in Kamioka mine. Current status of SK-Gd project and the physics work being performed in EGADS will be presented here.

Conflicting messages concerning current strategies against research misconduct in Japan: a call for ethical spontaneity.

PubMed

Asai, Atsushi; Okita, Taketoshi; Enzo, Aya

2016-08-01

The Japanese government has asserted that the purpose of scientific activities is to search for the truth about the world and contribute to public interest of the humanities and claimed that research misconduct should occur under no circumstances ever. The revealing of each new case of research misconduct leads to the establishment of investigation committees and research guidelines, as well as punishments for the transgressors. However, we wonder if Japanese researchers are receiving different messages that might undermine the purpose of the former messages. First, Japan's policies on science and technology have been created to comprise an integration of merit-based evaluations, principles of competition and a concentrated and unbalanced distribution of research funding, leading to decreases in ordinary research funding for the researchers and an increase in fierce research competition. Second, Japanese government and society as a whole continue to send the researchers messages such as 'Only results matter', 'Be No. 1 as a top priority' and 'All we need now is scientific progress'. Third, cultural peculiarities may explain some of the actions relevant to research misconducts currently noted in Japan. We argue that it is essential to re-examine and improve the governmental policies and evaluation methods for research achievements need to be more multifaceted. In order to have the researchers act according to ethics, it is essential for them to reaffirm their objectives for working in the fields of science and medicine and the importance of balancing their personal profit with the greater cause for entering into this field.

Current theorizing on socioeconomic status (SES) focuses on the availability of resources and the freedom they afford as a key determinant of the association between high SES and stronger orientation toward the self and, by implication, weaker orientation toward others. However, this work relies nearly exclusively on data from Western countries where self-orientation is strongly sanctioned. In the present work, we predicted and found that especially in East Asian countries, where other-orientation is strongly sanctioned, high SES is associated with stronger other-orientation as well as with self-orientation. We first examined both psychological attributes (Study 1, N = 2,832) and socialization values (Study 2a, N = 4,675) in Japan and the United States. In line with the existent evidence, SES was associated with greater self-oriented psychological attributes and socialization values in both the U.S. and Japan. Importantly, however, higher SES was associated with greater other orientation in Japan, whereas this association was weaker or even reversed in the United States. Study 2b (N = 85,296) indicated that the positive association between SES and self-orientation is found, overall, across 60 nations. Further, Study 2b showed that the positive association between SES and other-orientation in Japan can be generalized to other Confucian cultures, whereas the negative association between SES and other-orientation in the U.S. can be generalized to other Frontier cultures. Implications of the current findings for modernization and globalization are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Palliative care for heart failure (HF) patients is recommended in Western guidelines, so this study aimed to clarify the current status of palliative care for HF patients in Japan.Methods and Results:A survey was sent to all Japanese Circulation Society-authorized cardiology training hospitals (n=1,004) in August 2016. A total of 544 institutions (54%) returned the questionnaire. Of them, 527 (98%) answered that palliative care is necessary for patients with HF. A total of 227 (42%) institutions held a palliative care conference for patients with HF, and 79% of the institutions had <10 cases per year. Drug therapy as palliative care was administered at 403 (76%) institutions; morphine (87%) was most frequently used. Among sedatives, dexmedetomidine (33%) was administered more often than midazolam (29%) or propofol (20%). Regarding the timing of end-of-life care, most institutions (84%) reported having considered palliative care when a patient reached the terminal stage of HF. Most frequently, the reason for the decision at the terminal stage was "difficulty in discontinuing cardiotonics." A major impediment to the delivery of palliative care was "difficulty predicting an accurate prognosis." This large-scale survey showed the characteristics of palliative care for HF in Japan. The present findings may aid in the development of effective end-of-life care systems.

The adequate criteria for late-onset hypogonadism (LOH) diagnosis, including serum testosterone levels, type (total or free testosterone) and duration of androgen replacement therapy, and evaluations of treatment effectiveness remain controversial. To evaluate the current status of medical treatment for LOH in Japan, the first nationwide survey were performed. A total of 35 questionnaires answered by urologists in high-volume facilities were analyzed. The median numbers of patients with hypogonadism-related symptoms per month were 10. Aging Male Symptom Score, International Index of Erectile Function, and International Prostate Symptom Score questionnaires were widely used for questionnaires. The diagnostic criteria for LOH varied. Among the patients who presented with hypogonadism-related symptoms, the mean proportion of patients undergoing treatment for LOH was 62.3%. In Japan, LOH was treated not only with testosterone enanthate injections or testosterone ointment but also with Kampo medicine. In many facilities, LOH treatment effectiveness was assessed after a 3-month period. Efficacy was assessed in different ways. Treatment effectiveness rate ranged from 30% to 80%. The duration of LOH treatment was not fixed and was established individually by both the patient and treating physician. This study showed that the real clinical practices for LOH are very diverse, and a general consensus is needed.

Objective To investigate the relationship between personal experience of the Great East Japan Earthquake and various disease types among nursery school children. Design We conducted a nationwide survey of nursery school children born between 2 April 2006 and 1 April 2007. Nursery school teachers completed questionnaires if they agreed to join the study. Questionnaire items for children consisted of their birth year and month, sex, any history of moving into or out of the current nursery school, presence of diseases diagnosed by a physician at the age of 66–78 months and type of disaster experience. The survey was conducted from September 2012 to December 2012. Setting Japan, nationwide. Participants A total of 60 270 nursery school children were included in the analysis, 840 of whom experienced the disaster on 11 March 2011. Main outcome measures The health status of children 1.5 years after the disaster based on nursery school records. Results Experiencing the disaster significantly affected the prevalence of overall and individual diseases. Furthermore, there was a difference in disease prevalence between boys and girls. In boys, experiencing the tsunami (OR 2.53, 95% CI 1.22 to 5.24) and living in an evacuation centre (OR 2.92, 95% CI 1.46 to 5.83) were remarkably associated with a higher prevalence of atopic dermatitis, but these trends were not observed among girls. Instead, the home being destroyed (OR 3.50, 95% CI 2.02 to 6.07) and moving house (OR 4.19, 95% CI 2.01 to 8.71) were positively associated with a higher prevalence of asthma among girls. Conclusions Our study indicates that experiencing the disaster may have affected the health status of nursery school children at least up to 1.5 years after the disaster. Continuous monitoring of the health status of children is necessary to develop strategic plans for child health. PMID:28589008

Mahoney, Louise A; Bayley, Peter J

2018-01-01

Pain is a pervasive, debilitating disorder that is resistant to long-term pharmacological interventions. Although psychological therapies such as cognitive behavior therapy demonstrate moderate efficacy, many individuals continue to have ongoing difficulties following treatment. There is a current trend to establish complementary and integrative health interventions for chronic pain, for which yoga has been found to have exciting potential. Nevertheless, an important consideration within the field is accessibility to adequate care. Telehealth can be used to provide real-time interactive video conferencing leading to increased access to health care for individuals located remotely or who otherwise have difficulty accessing services, perhaps through issues of mobility or proximity of adequate services. This article assesses the current status and feasibility of implementing tele-yoga for chronic pain. Methodological limitations and recommendations for future research are discussed. PMID:29637012

2018-04-01

To understand the properties of tides and tidal currents on the Pacific shelf off the southeastern coast of Hokkaido, Japan, we analyzed time series of 9 current meters that were moored on the shelf for 1 month to 2 years. Diurnal tidal currents such as the K1 and O1 constituents were more dominant than semi-diurnal ones by an order of magnitude. The diurnal tidal currents clearly propagated westward along the coast with a typical phase velocity of 2 m s-1 and wavelength of 200 km. Moreover, the shape and phase of the diurnal currents measured by a bottom-mounted ADCP were vertically homogeneous, except in the vicinity of the bottom boundary layer. These features were very consistent with theoretically estimated properties of free baroclinic coastal-trapped waves of the first mode. An annual (semi-annual) variation was apparent for the phase (amplitude) of the O1 tidal current, which was correlated with density stratification (intensity of an along-shelf current called the Coastal Oyashio). These possible causes are discussed in terms of the propagation and generation of coastal-trapped waves.

Policy review: Japan-Philippines Economic Partnership Agreement (JPEPA)--analysis of a failed nurse migration policy.

2014-02-01

In 2008, the bilateral Japan-Philippines Economic Partnership Agreement took effect. Contained within this regional free trade agreement are unique provisions allowing exchange of Filipino nurses and healthcare workers to work abroad in Japan. Japan's increasing need for healthcare workers due to its aging demographic and the Philippines need for economic development could have led to shared benefits under the Japan-Philippines Economic Partnership Agreement. However, 4 years following program implementation, results have been disappointing, e.g., only 7% of candidates passing the programs requirements since 2009. These disappointing results represent a policy failure within the current Japan-Philippines Economic Partnership Agreement framework, and point to the need for reform. Hence, amending the current Japan-Philippines Economic Partnership Agreement structure by potentially adopting a USA based approach to licensure examinations and implementing necessary institutional and governance reform measures may be necessary to ensure beneficial healthcare worker migration for both countries.

Contemporary issues concerning informed consent in Japan based on a review of court decisions and characteristics of Japanese culture

PubMed Central

2014-01-01

Background Since Japan adopted the concept of informed consent from the West, its inappropriate acquisition from patients in the Japanese clinical setting has continued, due in part to cultural aspects. Here, we discuss the current status of and contemporary issues surrounding informed consent in Japan, and how these are influenced by Japanese culture. Discussion Current legal norms towards informed consent and information disclosure are obscure in Japan. For instance, physicians in Japan do not have a legal duty to inform patients of a cancer diagnosis. To gain a better understanding of these issues, we present five court decisions related to informed consent and information disclosure. We then discuss Japanese culture through reviews of published opinions and commentaries regarding how culture affects decision making and obtaining informed consent. We focus on two contemporary problems involving informed consent and relevant issues in clinical settings: the misuse of informed consent and persistence in obtaining consent. For the former issue, the phrase "informed consent" is often used to express an opportunity to disclose medical conditions and recommended treatment choices. The casual use of the expression "informed consent" likely reflects deep-rooted cultural influences. For the latter issue, physicians may try to obtain a signature by doing whatever it takes, lacking a deep understanding of important ethical principles, such as protecting human dignity, serving the patient’s best interest, and doing no harm in decision-making for patients. There is clearly a misunderstanding of the concept of informed consent and a lack of complete understanding of ethical principles among Japanese healthcare professionals. Although similar in some respects to informed consent as it originated in the United States, our review makes it clear that informed consent in Japan has clear distinguishing features. Summary Japanese healthcare professionals should aim to understand

Although the artificial urinary sphincter (AUS) is one of the most effective surgical treatments for severe urinary incontinence, little is known about its use in Japan. A nationwide survey was done to determine contemporary trends in AUS use and its long-term durability. Data on AUS units sold in Japan were provided directly by Takai Hospital Supply Co., Ltd., Tokyo, Japan, and a survey form was sent to all 44 institutes where AUS implantation had been carried out. The survey included various demographic and preoperative variables, surgical variables, and postoperative outcomes. Between 1994 and 2007, a total of 100 AUS devices had been provided in Japan. Of the 44 institutes, 24 responded to the survey, and a total of 64 patients were enrolled in the study. Post-urological surgery incontinence accounted for 81.3% of the indications. During the mean follow-up of 50 months, mechanical failure occurred in four (6.2%), and the device was removed in 13 (20.3%) due to infection (14.0%), erosion (4.7%), or urination difficulty (1.5%). Of the 58 patients evaluated, 91.4% reported social continence. Five- and 10-year failure-free rates were 74.8% and 70.1%, respectively. On multivariate analysis, operative time was an independent predictor of treatment failure (P = 0.0334). Considering recent trends in prostate surgery, the AUS may be significantly underused in Japan. Although excellent long-term durability has been achieved, a learning effect appears to be evident. The Japanese urological community needs to provide appropriate patients with this treatment option.

Installation and testing are planned for a Southern California Edison substation. A project overview and progress under the first phase will be reported.

Current status of chirality in agrochemicals.

PubMed

Jeschke, Peter

2018-04-27

The agrochemical industry is continuously searching for new pesticides to develop products with optimal efficacy, lower application rates in the field, increased selectivity, favorable toxicological and environmental safety, enhanced user friendliness and better economic viability. One strategy to achieve these ambitious goals makes use of the unique properties of molecules containing asymmetric centers. In the past, many natural products and their congeners have been a source of inspiration for designing new active ingredients, and the molecular structure of the resulting molecules have become increasingly complex. 30% contain fragments with asymmetric centers. However, despite the enormous progress that has been made in catalytic asymmetric processes over the last decade, only few agrochemicals are produced in enantiomerically pure or enriched form on an industrial scale. Since 2007, around 43% of the 44 launched products (insecticides, acaricides, fungicides, nematicides, and herbicides) contain one or more asymmetric centers in the molecule (≈ 47 %) and most of them were launched as racemic mixtures of enantiomers or diastereomers. This review gives an overview of the current status of chiral agrochemicals launched over the past 10 years and describes the inherently connected challenges of modern agricultural chemistry by managing important aspects resulting from stereochemistry of these innovative products.

2011-04-01

Although functional gastrointestinal (GI) disorders has been paid more attention recently in Japan, similar to Western countries, the clinical characteristics of dyspeptic patients, current diagnostic approach to dyspeptic patients and current standard treatments for dyspeptic patients are not well known in Japan. This review, in the most part, summarizes two topics about Japanese dyspeptic patients. The first topic is the pros and cons of the diagnosis of Japanese dyspeptic patients using Rome III classification on the basis of our data and the second topic deals with standard treatments for dyspeptic patients-especially by primary care doctors in Japan. We conducted a PubMed search using the following key words alone or in combination: functional dyspepsia (FD), medical treatment, Rome III classification and Japanese. The Rome III classification for FD does not adequately identify a large proportion of Japanese dyspeptic patients, primarily due to their earlier presentation for medical evaluation. There are many kinds of options for the treatment of FD in Japan: proton-pump inhibitors, histamine H(2) receptor antagonists, mucoprotective agents, Japanese traditional herbal medicines, Helicobacter pylori eradication therapy and prokinetics. Under the current situation, Japanese primary care doctors choose drugs according to each subtype of FD, which means that they prescribe medicine according to the pathogenesis of each patient. While the Rome III classification seems logical, some aspects need further evaluation for Japanese dyspeptic patients. Japanese primary care doctors choose drugs appropriately based on the pathogenesis of FD. However, efforts to further elucidate underlying pathophysiologic mechanisms and identify the appropriate patient population using modified Rome classification will be required. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

Contrast-enhanced endoscopic ultrasonography: advance and current status

PubMed Central

2014-01-01

Endoscopic ultrasonography (EUS) technology has undergone a great deal of progress along with the color and power Doppler imaging, three-dimensional imaging, electronic scanning, tissue harmonic imaging, and elastography, and one of the most important developments is the ability to acquire contrast-enhanced images. The blood flow in small vessels and the parenchymal microvasculature of the target lesion can be observed non-invasively by contrast-enhanced EUS (CE-EUS). Through a hemodynamic analysis, CE-EUS permits the diagnosis of various gastrointestinal diseases and differential diagnoses between benign and malignant tumors. Recently, mechanical innovations and the development of contrast agents have increased the use of CE-EUS in the diagnostic field, as well as for the assessment of the efficacy of therapeutic agents. The advances in and the current status of CE-EUS are discussed in this review. PMID:25038805

The field of holographic particulate measurements continues to be very active with many new applications in such diverse fields as bubble chamber recording and contaminant measurements in small vials. The methods have also been extended to measure velocity distributions of particles within a volume, particularly by the application of subsequent image processing methods. These techniques could be coupled with hybrid systems to become near real time. The current status of these more recent developments is reviewed.

Perinatal depression is prevalent worldwide. However, there are few available studies that discuss the different cultural factors affecting perinatal depression within Asian countries. This study aims to compare the literature regarding related factors relating to perinatal depression in India and Japan, and to synthesize the evidence common to both countries in addition to the country-specific evidence. We conducted a systematic review using several databases (CINAHL, MEDLINE, Pubmed, Ovid, SCOPUS, IndMED, and ICHUSI). Keywords were "antenatal depression" or "postpartum depression", and "India" or "Japan". Both Japanese and English language papers were reviewed. The identified evidence was compared between the two countries, as well as with non-Asian countries based on previous reports. In total, 15 articles on India and 35 on Japan were reviewed. Although several factors were shared between the two countries as well as with other non-Asian countries (vulnerable personality, being abused, age, marital conflict, and lower socio-demographic status), some differing factors were identified between India and Japan and non-Asian countries; India: poor socioeconomic status, living only with the husband, pregnancy not welcomed by the husband, a female baby, and poor relationship with in-laws; Japan: infertility treatment, conflict with work-life balance, poor relationships with biological mother or in-laws, and concerns about social relations with the other mother's friends. To conclude, involving the family and community may be important for implementing both global standardized and culture-specific interventions. In India, treatment involving the in-laws may be effective because large family structure is a significant predictor of perinatal depression. In Japan, a family/community approach involving not only the mother's family of origin but also the working environment is essential.

To assess the current status of international ophthalmic publications. A collection of 55,591 original articles were found by an on-line National Library of Medicine database Medline search for 32 international ophthalmic journals during a 15-year period from 1988 to 2002 (internet access, November 11-13, 2003). The contributions to international ophthalmic publications were by 49.5% from North America, 31.3% from Western Europe, 15.1% from Asia and Oceania, 2.2% from Middle East, 0.85% from Central and South America, 0.53% from Eastern Europe, and 0.47% from Africa. Countries of Asia and Oceania showed an increasing trend in contributions while North America had a decreasing productivity in a relative sense. The top 10 productive countries were USA, United Kingdom, Japan, Germany, Canada, Australia, Italy, Netherlands, Sweden, and France. Among the Asian countries India ranked 13th, China 18th, and Korea 21st. When related to population, small countries such as Israel, France, Finland, Sweden, and Denmark were more productive. When related to economic productivity as defined by GDP, Israel, the United Kingdom, Australia, Finland, and Sweden were among the most productive countries, whereas rich countries such as Japan and Germany had a lower number of publications relative to their GDP. As regards clinical research in terms of randomized controlled trials, The USA was by far the most productive. The number of authors per article has shown an increasing trend worldwide, so that Japan and France had a significantly larger proportion of multiauthored articles. There is an increasing trend in the productivity of international ophthalmic publications from non-English-speaking countries including Japan, China, and Korea.

Initiatives by the government and physician groups to improve awareness of medical ethics: Challenges in Japan

PubMed Central

MORIOKA, Yasuhiko

2012-01-01

Physicians have been required to possess high ethical standards, as medical practice is directly involved with patients' lives. Although ethics arise out of an individual's consciousness, ethical regulations imposed by the nation/government together with self-regulation by physician groups are important in the practice of ethics, for which reason countries around the world undertake various initiatives. This paper investigates physician licensure, organizations governing physician status, the role of physician groups, and the actual conditions of lifelong learning and ethics education in developed countries worldwide, in contrast with which it throws problems in the situation in Japan into relief. Organizations governing physician status, the form of medical associations, and the improvement of lifelong learning are pointed out as critical issues especially in Japan. PMID:22498978

Genetic cancer vaccines: current status and perspectives.

PubMed

Aurisicchio, Luigi; Ciliberto, Gennaro

2012-08-01

The recent approval of the first therapeutic cancer vaccine by the US Regulatory Agency represents a breakthrough event in the history of cancer treatment. The past scepticism towards this type of therapeutic intervention is now replaced by great expectations. The field is now moving towards the development of alternative vaccination technologies, which are capable of generating stronger, more durable and efficient immune responses against specific tumour-associated antigens (TAAs) in combination with cheaper and more standardised manufacturing. In this context, genetic vaccines are emerging among the most promising methodologies. Several evidences point to combinations of different genetic immunisation modalities (heterologous prime/boost) as a powerful approach to induce superior immune responses and achieve greater clinical efficacy. In this review, we provide an overview of the current status of development of genetic cancer vaccines with particular emphasis on adenoviral vector prime/DNA boost vaccination schedules. We believe that therapeutic genetic cancer vaccines have the strong potential to become an established therapeutic modality for cancer in next coming years, in a manner similar to what have now become monoclonal antibodies.

Political economy of tobacco control policy on public health in Japan.

Desapriya, E B R; Iwase, Nobutada; Shimizu, Shinji

2003-02-01

Tobacco use, particularly smoking, remains the number one cause of preventable disease and mortality in Japan. This review of the tobacco control policy and public health is the first to offer a composite review of the subject within Japan. This review attempts to evaluate the most important aspects of the current political economy of the tobacco control policy, and concludes that more effective control policies must be employed to minimize the impact of smoking on the public's health in Japan. Further the article attempts to place the approaches in the larger context of tobacco control, providing a vision for the future of tobacco prevention and control based on current knowledge. Tobacco use will remain the leading cause of preventable illness and death in Japan, until tobacco prevention and control efforts are commensurate with the harm caused by tobacco. Taken together, the results of various studies have clearly shown that control measures can influence tobacco smoking patterns, and in turn, the rate of tobacco-related problems. Government tobacco taxes have not kept pace with inflation for years. Availability of tobacco is virtually unlimited with easy access and the prices being very low due to the strong currency of Japan. Thus Japan must be one of the most tobacco accessible countries. It is important to ensure that people are not conditioned to smoke tobacco by an unduly favourable economic and commercial environment. For that reason, prevention advocates have called for substantial regulation of tobacco products and appeal for both tobacco tax increases and tobacco taxes to be indexed to inflation. In this review, present tobacco related public health policies in Japan are discussed with implication for prevention of tobacco related problems. Continued research in this area will be necessary to determine the most effective policies of reducing tobacco related problems in Japan.

[Current situation of suicide in Japan, and what pharmacists contribute to suicide prevention].

PubMed

Matsumoto, Toshihiko

2013-01-01

  In Japan, a national countermeasure has been forwarded since the enactment of the Basic Act on Suicide Countermeasures in 2006 and the Comprehensive Suicide Prevention Initiative in 2007. The distinctive policy of the Japanese countermeasure is expressed as the word, "comprehensive," which means that suicide prevention may not only be carried out only by mental health measures but also by comprehensive measures including chance of administrative practices. This policy is proper, although mental health measures appear to be too simple inclining to psychiatric treatments for the classic type of "depression" by a pharmacotherapy. The authors have insisted that mental health measures including psychiatric treatments are also required to be more comprehensive. This paper describes that benzodiazepine (BZ)-abuse problems including overdosing by suicidal intents have got worse recently as psychiatric clinics have increased and most of BZ abusers obtain the abused drugs form psychiatrists. This current situation indicates that pharmacists need to monitor psychiatrists' prescribing behavior and qualities of psychiatric treatment is required to be refined, suggesting pharmacists may be one of the "Gate Keeper," as supporting resources for suicide prevention. Additionally, this paper explained that basic attitudes and responses acquired by pharmacists as a supporter for suicide prevention.

The present situation of prophylactic vaccination in Japan for travel abroad.

PubMed

Nakano, Takashi

2008-11-01

The current situation of vaccination in Japan is reviewed from a viewpoint of overseas travelers. Vaccinations before travel to developing countries, where the risk of infection is high, are recommended for two reasons: "individual protection" and "prevention of communicable disease importation". However, there are problems in Japan; some vaccines available commonly in foreign nations are not approved in Japan and the vaccination schedule is not convenient for travelers. Vaccination is sometimes needed also for travel to Europe and North America. This is because certain vaccinations are required for entering school or studying abroad. In Japan, there is no regulation which recommends vaccination as an entrance requirement. Compared with other nations, Japanese children receive fewer vaccines routinely. On the other hand, there are different features from other industrialized nations, such as routine childhood BCG vaccination and immunization against Japanese encephalitis in Japan. Compared with foreign nations, awareness as regards "travel medicine" is lower in Japan. Recognizing this situation will lead to improvement of vaccination of travelers.

The erosion of social capital in more unequal societies is one mechanism for the association between income inequality and health. However, there are relatively few multi-level studies on the relation between income inequality, social capital and health outcomes. Existing studies have not used different types of health outcomes, such as dental status, a life-course measure of dental disease reflecting physical function in older adults, and self-rated health, which reflects current health status. The objective of this study was to assess whether individual and community social capital attenuated the associations between income inequality and two disparate health outcomes, self-rated health and dental status in Japan. Self-administered questionnaires were mailed to subjects in an ongoing Japanese prospective cohort study, the Aichi Gerontological Evaluation Study Project in 2003. Responses in Aichi, Japan, obtained from 5715 subjects and 3451 were included in the final analysis. The Gini coefficient was used as a measure of income inequality. Trust and volunteering were used as cognitive and structural individual-level social capital measures. Rates of subjects reporting mistrust and non-volunteering in each local district were used as cognitive and structural community-level social capital variables respectively. The covariates were sex, age, marital status, education, individual- and community-level equivalent income and smoking status. Dichotomized responses of self-rated health and number of remaining teeth were used as outcomes in multi-level logistic regression models. Income inequality was significantly associated with poor dental status and marginally significantly associated with poor self-rated health. Community-level structural social capital attenuated the covariate-adjusted odds ratio of income inequality for self-rated health by 16% whereas the association between income inequality and dental status was not substantially changed by any social capital

Residents of long-term care facilities for the elderly are vulnerable to health care-associated infections. However, compared to medical institutions, long-term care facilities for the elderly lag behind in health care-associated infection control and prevention. We conducted a epidemiologic study to clarify the current status of infection control in long-term care facilities for the elderly in Japan. A questionnaire survey on the aspects of infection prevention and control was developed according to SHEA/APIC guidelines and was distributed to 617 long-term care facilities for the elderly in the province of Osaka during November 2016 and January 2017. The response rate was 16.9%. The incidence rates of health care-associated infection outbreaks and residents with health care-associated infections were 23.4 per 100 facility-years and 0.18 per 1,000 resident-days, respectively. Influenza and acute gastroenteritis were reported most frequently. Active surveillance to identify the carrier of multiple drug-resistant organisms was not common. The overall compliance with 21 items selected from the SHEA/APIC guidelines was approximately 79.2%. All facilities had infection control manuals and an assigned infection control professional. The economic burdens of infection control were approximately US$ 182.6 per resident-year during fiscal year 2015. Importantly, these data implied that physicians and nurses were actively contributed to higher SHEA/APIC guideline compliance rates and the advancement of infection control measures in long-term care facilities for the elderly. Key factors are discussed to further improve the infection control in long-term care facilities for the elderly, particularly from economic and social structural standpoints.

Vast resources are being spent on three continents, preparing for the commercialization of HDTV. The forces that together will launch this new industry are moving at dizzying speeds. This paper covers the highlights of events past and present and offers some predictions for the future. Difficult standards problems that keep brakes on the industry, and that will continue for some time to come. Standards committees have been set up around the world and are hard at work. It is a job with considerable technical and political challenges. By the time major plans and resources come together for commercialization of HDTV, one can trust that there will be adequately stable standards. But to observe the current status is to see a mess. High definition is not only consumer television. Because of its versatility, it is much more likely to find its way first into areas offering high returns such as medicine, education, printing, corporate communications, military and space, and even criminal control. HDTV is very likely to deliver movies and cultural events to theaters, and may also become the platform for a new generation of computers.

The current status of oral contraceptive clinical development in Japan.

PubMed

Kuwabara, Y

1989-01-01

Since the oral contraceptive guideline was issued in April 1987, Japanese pharmaceutical firms have been asking physicians to perform clinical studies of the low-dose OCs. At present, eight products from six companies are under clinical development. Ethinyl estradiol (30-35 micrograms per tablet) as an estrogen component is common to all the test drugs. The progestin component in each OC is norethindrone, levonorgestrel, or desogestrel. Phase I clinical studies on small numbers of healthy volunteers showed that they could tolerate the test drugs without any serious complaints. The effects on endocrine systems, including the inhibition of ovulation, were also examined. Pharmacokinetic parameters of active ingredients were comparable to those of Western women, and no substantial difference seemed to exist between Japanese and Western women. As an example, the results of phase I studies of OJK-777 (Ortho-Novum 7/7/7) are mentioned. Phase III clinical studies, which are "open studies," are now under progress with more than 3,000 women. The major objectives are to examine (1) how well the drugs are tolerated, and the dropout rates; (2) the effects on cycle control, especially bleeding patterns; (3) effects on the cardiovascular system, including coagulation and lipid metabolism; (4) effects on hormone secretions. Although some women have been taking the test drugs for more than 12 cycles, overall statistics are not yet available, because the guideline requires long-term administration (for more than 24 cycles). However, some characteristic features observed thus far are discussed.

Recently the need to manage food allergies in schools has been growing. This study aimed to examine the current status of managing food allergies in schools in Seoul, Korea. A questionnaire survey was conducted in cooperation with the School Dietician Association during April 2009. Among the participating 154 schools, a total of 109 (71%) were determining students' food allergy status through parental surveys based on self-reported food allergies. A total of 72 (47%) had experienced student visits to a school health room due to food allergies within one year before the survey. Over 80 percent of the schools relied on self-care only without any school-wide measures for food allergies in place. Among the 890 menu items most frequently served in school lunch programs, a total of 664 (75%) were found to contain more than one food allergen. It is highly suggested that preventive plans and treatment measures should be established to manage food allergies in schools.

Suicide rates have been related to educational level and other socioeconomic statuses. However, no prospective study has examined the association between educational level and the risk of suicide in Japan. We examined the association of education level and suicide risk in a population-based cohort of Japanese men and women aged 40-59 years in the Japan Public Health Center-based Prospective Study Cohort I. In the baseline survey initiated in 1990, a total of 46 156 subjects (21 829 men and 24 327 women) completed a self-administered questionnaire, which included a query of educational level, and were followed up until the end of December 2011. Educational levels were categorized into four groups (junior high school, high school, junior or career college, and university or higher education). During a median follow-up of 21.6 years, the hazard ratios (HRs) and 95% confidence intervals (CIs) of suicide according to educational level were estimated using the Cox proportional hazards regression model adjusted for age; study area; previous history of stroke, ischemic heart disease, or cancer; self-reported stress; alcohol consumption; smoking; living with spouse; and employment status. A total of 299 deaths attributed to suicide occurred. The HR for university graduates or those with higher education versus junior high school graduates was 0.47 (95% CI, 0.24-0.94) in men, and that for high school graduates versus junior high school graduates was 0.44 (95% CI, 0.24-0.79) in women. High educational levels were associated with a reduced risk of suicide for both Japanese men and women.

This study was aimed to investigate the current clinical status of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) in Korea based on a National Health Insurance (NHI) database between 2011 and 2014. The claims data of ESD for EGC in Korean NHI were reviewed using material codes of Health Insurance Review and Assessment Service between November 2011 and December 2014. The current clinical status was analyzed in terms of treatment pattern, in-hospital length of stay (LOS), total medical costs, and en bloc resection rate according to the hospital type. A total of 23,828 cases of ESD for EGC were evaluated. ESD was performed in 67.4% of cases in tertiary care hospitals, 31.8% in general hospitals, and 0.8% in hospitals, respectively. The median LOS was 5 days, and total median medical costs was approximately 1,300 US dollars. En bloc resection rate was 99%; 8.5% of cases underwent additional treatment within 90 days ESD, and 5.5% in 91 to 365 days after ESD. The clinical status was not significantly different according to the year and hospital type. A majority of ESD for EGC were performed in tertiary care hospitals in Korea. The clinical status showed excellent clinical outcomes and did not differ by the year and between the types of hospitals in Korea.

In Japan, rotavirus hospitalisation occurs at a rate from 2.8 to 13.7 per 1000 child-years among children age less than 5 years, and it imposes a substantial burden to the healthcare system in the country. While both monovalent (RV1) and pentavalent (RV5) rotavirus vaccines are licensed in Japan, neither has been incorporated in the national infant immunization programme. In this study, we estimated vaccine effectiveness (VE) in Japan. This study was conducted in Yuri-Kumiai General Hospital located in a city in the north-western part of Japan. Age-eligible children for rotavirus vaccination were enrolled if they were hospitalized for rotavirus gastroenteritis between September 2013 and August 2016. Rotavirus gastroenteritis was defined by the detection of rotavirus antigen by immunochromatography. "Vaccinated" was defined as infant inoculated with at least one dose of either RV1 or RV5. A conditional logistic regression analysis was performed by modelling the year of birth, year of admission, residence of the children and vaccination status, and by matching the age of cases with that of test-negative controls. The adjusted odds ratio of the vaccinated over unvaccinated was then used to calculate VE in the formula of (1 - adjusted odds ratio) × 100. Out of the 244 patients enrolled, rotavirus antigen was detected in 55 (22.5%) of whom 10 (18.2%) were vaccinated, whereas 94 (49.7%) of 189 test-negative controls were vaccinated. During the study period, the vaccine uptake rate in the controls increased from 36.2% to 61.8%. On the other hand, the vaccination coverage over the three years was 64.2% in Yuri-Honjo city (three quarters of the catchment), and 91.4% in Nikaho city (one quarter of the catchment). The VE was calculated to be 70.4% (95% confidence interval: 36.0-86.4%, P = 0.002). The point estimate of the VE was lower but its 95% confidence interval overlaps those of the efficacies obtained from clinical trials in Japan. The rotavirus vaccine was

We briefly review several possible particle candidates for a weakly interactive massive particle (WIMP) and dark matter that have recently been considered in the literature. We pay particular attention to the lightest neutralino of supersymmetry as it remains the best motivated candidate for dark matter and also shows excellent detection prospects. Finally we briefly review some alternative scenarios that can considerably alter properties and prospects for the detection of dark matter obtained within the standard thermal WIMP paradigm.

Epidemiological studies have suggested a protective effect of dietary fiber intake on breast cancer risk while the results have been inconsistent. Our study aimed to investigate the association between dietary fiber intake and breast cancer risk and to explore whether this association is modified by reproductive factors and hormone receptor status of the tumor. A total of 44,444 women aged 45 to 74 years from the Japan Public Health Center-based Prospective Study were included in analyses. Dietary intake assessment was performed using a validated 138-item food frequency questionnaire (FFQ). Hazard ratios (HRs) and 95% confidence intervals (CIs) for breast cancer incidence were calculated by multivariate Cox proportional hazards regression models. During 624,423 person-years of follow-up period, 681 breast cancer cases were identified. After adjusting for major confounders for breast cancer risk, inverse trends were observed but statistically non-significant. Extremely high intake of fiber was associated with decreased risk of breast cancer but this should be interpreted with caution due to limited statistical power. In stratified analyses by menopausal and hormone receptor status, null associations were observed except for ER-PR- status. Our findings suggest that extreme high fiber intake may be associated with decreased risk of breast cancer but the level of dietary fiber intake among Japanese population might not be sufficient to examine the association between dietary fiber intake and breast cancer risk.

Interplay of politics and law to promote health: improving economic equality and health: the case of postwar Japan.

PubMed

Bezruchka, Stephen; Namekata, Tsukasa; Sistrom, Maria Gilson

2008-04-01

The health situation in Japan after World War II was extremely poor. However, in less than 35 years the country's life expectancy was the highest in the world. Japan's continuing health gains are linked to policies established at the end of World War II by the Allied occupation force that established a democratic government. The Confucian principles that existed in Japan long before the occupation but were preempted during the war years were reestablished after the war, facilitating subsequent health improvements. Japan's good health status today is not primarily the result of individual health behaviors or the country's health care system; rather, it is the result of the continuing economic equality that is the legacy of dismantling the prewar hierarchy.

Traditional Japanese dietary culture might be a factor contributing to the high life expectancy in Japan. As little is known about what constitutes traditional and modern eating in Japan, the aims of the current study were to (1) comprehensively compile and systematize the various facets of traditional and modern eating; and (2) investigate whether these facets also apply to traditional and modern eating in Japan. In Study 1, an extensive international literature review was performed. Forty-five facets of traditional and modern eating were compiled and systematized into the dimensions of what and how people eat, and into eleven separate subdimensions. In Study 2, 340 adults from Japan answered a questionnaire. Results showed that traditional and modern eating in Japan is reflected in both what and how people eat. Within these two dimensions, ten subdimensions were found: the ingredients, processing, temporal origin, spatial origin, and variety of consumed foods, as well as temporal, spatial, and social aspects, appreciation, and concerns when eating. This study provides a broad compilation of facets of traditional and modern eating in Japan. Future research should investigate how these facets are related to life expectancy and health.

Allergy diagnosis and immunotherapy in Korea rely mostly on imported allergen extracts. However, some allergens that are not important in Western countries are not commercially available, and even the same species of allergen source often displays differences in allergenicity due to amino acid sequence polymorphisms. Therefore, it is essential to prepare allergen extracts that reflect regional characteristics. Allergen standardization has been performed since 2009 with the support of the Korea Center for Disease Control and Prevention. Here, we summarize the current status of allergen standardization, focusing on the house dust mite and cockroach. Pollen allergens that are under investigation are also briefly described.

Porcine epidemic diarrhea (PED) is an emerging disease of pigs that has recently led to large numbers of piglet deaths in a number of countries of Eastern Asia and The Americas. The objective of the present study was to identify and compare risk factors associated with PED infection in locally and non-locally PED-exposed farms in Japan. A questionnaire was administered to a convenience selection of pig farms located throughout Japan. Questionnaires were administered between November 2013 (when the first case was reported in Japan) and August 2014. PED-positive farms (cases, n=124) were asked to provide information on their status (positive or negative) and select herd management practices for the two weeks prior to onset of PED clinical signs. Negative farms (controls, n=128) were given the same questionnaire and asked herd management practices for the two weeks prior to a given reference date. This date was assigned based on the date of PED occurrence in the town/prefecture in which the farm was located. Case and control farms were categorized as "locally exposed" if they were located within a 5km radius from a PED-infected farm and "non-locally exposed", otherwise. Logistic regression analysis was used to identify factors associated with PED infection. Two separate regressions were done for locally exposed and non-locally exposed farms using PED status (positive/negative) as the dependent variable. PED in locally-exposed farms was associated (P<0.05) with increased farm size (in 100 pig increments), shorter distances to the closest PED-positive farm (less than1,001m), and a disinfectant contact time of less than 20min. In non-locally exposed farms, PED was associated (P<0.05) with increased feed truck visits to the farm, no visit of the veterinarian, and again a disinfectant contact time of less than 20min. These findings suggest that the mechanisms of PED spread in Japan were different for farms closer to case-farms compared to farms that were further away from

Objective The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. Methods Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information on human resources, brachytherapy equipment, and suggestions for future directions of brachytherapy policy in Korea. Results The response rate of the survey was 88.3%. The average number of radiation oncologists per center was 2.3. At the time of survey, 28 centers (36.8%) provided brachytherapy to patients. Among the 28 brachytherapy centers, 15 (53.5%) were located in in the capital Seoul and its surrounding metropolitan areas. All brachytherapy centers had a high-dose rate system using 192Ir (26 centers) or 60Co (two centers). Among the 26 centers using 192Ir sources, 11 treated fewer than 40 patients per year. In the two centers using 60Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. Conclusion The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy. PMID:27102244

Tick-borne encephalitis virus (TBEV) causes mild or moderate febrile illness in humans that may progress to encephalitis, leading to severe long-term complications and sometimes death. TBEV is prevalent in the Eurasian continent and has been isolated in China, Japan and Republic of Korea (ROK). The TBEV isolates from Japan are of the Far-Eastern subtype; in ROK, the isolates are of the Western subtype; and all TBEV isolates in China are of the Far-Eastern subtype, except one strain that was identified most recently as the Siberian subtype. TBE is endemic to the northeast, northwest and southeast of China; only two confirmed TBE cases have been reported in Japan to date; and no TBE case has been confirmed in ROK. For TBE patients in China, the onset of disease is acute with no biphasic course for disease presentation. The clinical spectrum of disease phenotypes may be wider than currently understood, since serological evidence suggests the presence of TBEV infections in healthy people, indicating that asymptomatic or unspecific manifestations of TBEV infection may exist. The current treatment for TBE is supportive care. In China, vaccines against TBEV have been developed and are available with demonstrated immunogenicity and safety, although efficacy data are lacking. No vaccines are available in ROK or Japan.

Recent evidence has supported the concept that epithelial ovarian cancer (EOC) arises from the cells of the fallopian tube or endometrium. This study investigated current practice in Japan with respect to performing opportunistic bilateral salpingectomy (OBS) during gynecological surgery for benign disease for Ovarian Cancer Prevention. We mailed a questionnaire to 767 hospitals and clinics, comprising 628 accredited training institutions of the Japan Society of Obstetrics and Gynecology (JSOG), Japan Society of Gynecologic Oncology (JSGO), or Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy (JSGOE) and 139 private institutions with at least one JSGOE-certified licensed gynecologic laparoscopist. Among the 767 institutions, 444 (57.9%) provided responses, including 91 (20.6%) that were both JSGOE and JSGO accredited, 71 (16.0%) that were only JSGO accredited, 88 (19.8%) that were only JSGOE accredited, and 194 (43.7%) that were unaccredited. It was found that awareness and performance of OBS largely depended on the JSGO and/or JSGOE accreditation status. OBS was only performed at 54.0% of responding institutions and just 6.8% of the institutions were willing to participate in randomized controlled trials to validate this method for reducing the incidence of ovarian cancer. The JSOG Gynecologic Tumor Committee will announce its opinion on salpingectomy for ovarian cancer prevention to all JSOG members and will develop a system for monitoring the number of OBS procedures in Japan.

The current status and trend of clinical pharmacology in developing countries

PubMed Central

2013-01-01

Background Several international forums for promoting clinical pharmacology in developing countries have been held since 1980, and several clinical pharmacology programmes targeting developing countries were instituted such that the status of clinical pharmacology in developing countries is not where it was 50 years ago. Therefore, a survey and an appraisal of the literature on the current status of clinical pharmacology in developing countries were undertaken with a hope that it would enable development of appropriate strategies for further promotion of clinical pharmacology in these countries. Methods First, nine determinants (or enabling factors) for running a successful clinical pharmacology programme were identified, i.e., disease burden, drug situation, economic growth, clinical pharmacology activities, recognition, human capital, government support, international collaboration, and support for traditional/alternative medicines. These factors were then evaluated with regard to their current status in the developing countries that responded to an electronic questionnaire, and their historical perspective, using the literature appraisal. From these, a projected trend was constructed with recommendations on the way forward. Results Clinical pharmacology services, research and teaching in developing countries have improved over the past 50 years with over 90% of countries having the appropriate policies for regulation and rational use of medicines in place. Unfortunately, policy implementation remains a challenge, owing to a worsening disease burden and drug situation, versus fewer clinical pharmacologists and other competing priorities for the national budgets. This has led to a preference for training ‘a physician clinical pharmacologist’ in programmes emphasizing local relevancy and for a shorter time, and the training of other professionals in therapeutics for endemic diseases (task shifting), as the most promising strategies of ensuring rational use of

After purchase of radiotherapy equipment in 2003, classic radiation therapy in Serbia will reach the highest world level. In order to define the highest standards in radiation technology, we analyzed the current status and potential perspectives of radiation therapy. An analysis of present situation in the USA, assumed as the most developed in the world, was done. Available data, collected in the last 3 years (equipment assortment, therapy modalities, workload and manpower) for 284 radiotherapy centers, out of potential 2050, were analyzed. Results were presented as crude percentage and matched to point current status. The analysis showed that CLINAC accelerators are the most popular (82.7%), as well as, ADAC (43.7%) and Focus (CMS) (27.4%) systems for therapy planning. Movement towards virtual simulation is evident (59.3%), although classic "simulation" is not fully eliminated from the radiotherapy chain. The most popular brachytherapy afterloader is Microselectron HDR (71%). About 64.4% centers use IMPAC communication/verification/record system that seems more open than Varis. All centers practice modern radiotherapy modalities and techniques (CPRT, IMRT, SRS/SRT, TBI, IORT, IVBHRT, HDR BHRT, etc.). CT and MRI availability is out of question, but PET is available in 3% of centers, however this percentage is rapidly growing. Up to 350 new patients per year are treated by one accelerator (about 35 pts. a day). Centers are relatively small and utilize 2-3 accelerators on average. Average FTE staffing norm is 4 radiation oncologists, 2-3 medical radiotherapy physicists, about 3 certified medical dosimetrists and about 6 radiotherapy technologists. In the past 5 years relative stagnation in classic radiotherapy has been observed. In spite of substantial investments in technology and consequent improvements, as well as wide introduction of computers in radiotherapy, radiotherapy results have not changed significantly.

Assisted reproductive technology (ART) such as in vitro fertilization (IVF) and embryo transfer (ET) has been essential in the treatment of infertility. The world’s first IVF-ET baby was born in 1978 based on the technique developed by Dr. Robert Edwards and Dr. Patrick Steptoe.1) In Japan, the first IVF-ET birth was reported in 1983 by Prof. Masakuni Suzuki at Tohoku University School of Medicine.2,3) IVF-ET is a procedure used to achieve pregnancy that consists of extracting oocytes from an infertile woman, fertilizing them in vitro, and transferring fertilized eggs into the patient’s uterine cavity (Fig. 1). Since the first report of successful IVF-ET, numerous techniques related to ART, such as cryopreservation of oocytes and embryos, gamete intrafallopian transfer (GIFT), and microinsemination, have been developed and refined (Table 1). Herein we describe the history of basic research in IVF-ET that led to human applications, how the birth of the first IVF-ET baby was achieved in Japan, the current status of ART in Japan, issues related to ART, and future prospects for ART.

2014-01-01

Professionals in many different occupations, from psychiatrists, obstetricians, and pediatricians to nurses, midwives, pharmacists, clinical psychologists, public health nurses, and psychiatric social workers, are involved in perinatal mental healthcare. In order to enhance the function of such healthcare, it is necessary both to provide specialized training in each occupation and form a system and to smoothly conduct medical collaboration between different occupations. A deficiency in the medical function of perinatal mental healthcare greatly influences the mother and child's health, mental hygiene, and social life later in life. Therefore, a demand is seen for specialized staff and system formation capable of the following: 1) responding with appropriate perinatal management of female patients taking psychotropic drugs; 2) providing support and pregnancy consultation to female patients who wish to have children; and 3) properly handling postpartum mental disorder management, possibility of breastfeeding, and various issues that arise in mother-child relationships during upbringing. In the UK, the clinical guideline (NICE Clinical Guideline 45) for perinatal mental healthcare, which was created by the National Institute for Clinical Excellence (NICE), provides important guidelines on how to handle perinatal mental health. Aside from the NICE guideline, the Maudsley Prescribing Guidelines in Psychiatry indicates basic guidelines on prescribing perinatal drug therapy. In Japan, however, the current situation of perinatal mental healthcare is such that it has yet to be systemically developed. In this paper, we introduce the basic content in these British guidelines that should be noted. In addition, we consider the current status and future disposition of Japan's perinatal mental healthcare, with consideration for the differences in healthcare circumstances between Japan and the UK.

Background: The valley of death, which refers to the gap due to the lack of support for the translation of basic research to related clinical studies, exists in the field of translational cannabinoid research in Japan owing to regulations. Article 4 of the Cannabis Control Act (CCA) of 1948 prohibits the use of Cannabis -based medicines. Objectives: This study aimed to explore the history of the establishment of regulations on the medical use of Cannabis -based medicines and discuss the current status of cannabinoid research and its regulation in Japan. Methods: We conducted a literature review of nationally archived official documents from the end of World War II in 1945 to 1948, which is the year the CCA was established. The documents were examined, specifically focusing on the sequence of events. Results: We found three memoranda related to the establishment of the CCA. The establishment of law on controlling narcotics was instructed by the general headquarters (GHQ)/Supreme Commander for the Allied Powers (SCAP) during the period of occupation after World War II. However, the Japanese Government decided to regulate Cannabis separately from other narcotics. Item (ii) of article 4 in the CCA, which prohibits medical application of Cannabis , was included to protect farmers growing Cannabis for the hemp content. Conclusion: Current Japanese regulations prohibiting clinical research in phytocannabinoids were instituted during the postwar era of World War II. Scientific discoveries have advanced cannabinoid research and have led positive reforms of the regulation of Cannabis in other countries. Therefore, there is ample motivation and opportunity for Japanese stakeholders to revise article 4 of the CCA for the benefit of patients.

Japan's health statistics system, considered among the best in the world today, continually complies and organizes information about various infectious diseases. However, systematic surveillance was not conducted by the Ministry of Health and Welfare between World War II and the postwar period, creating a gap in health data. In contrast, the GHQ/SCAP/PHW. which was closely involved in health and medical reform during the Occupation, thoroughly investigated the health conditions of the Japanese people during this period. This article describes the trends in acute infectious diseases in Occupied Japan by using statistical records listed in the appendices of the "Weekly Bulletin", an official document of the GHQ/SCAP that is currently kept in the National Diet Library Modern Japanese Political History Materials Room.

2012-10-01

Previous growth in the utilization of medical imaging has led to numerous efforts to reduce associated spending. Although these have historically been directed toward unit cost reductions, recent interest has emerged by various stakeholders in curbing inappropriate utilization. Radiology benefits managers have widespread market penetration and have been promoted largely by the payer community as effective mechanisms to curb increases in imaging volume. The provider community has tended to favor real-time order entry decision support systems. These have demonstrated comparable effectiveness to radiology benefits managers in early projects but currently have only limited market penetration. In this first of a two-part series, the rationale for the development of utilization management programs will be discussed and their history and current status reviewed.

Neurovirulence safety testing of mumps vaccines--historical perspective and current status.

PubMed

Rubin, S A; Afzal, M A

2011-04-05

Many live, attenuated viral vaccines are derived from wild type viruses with known neurovirulent properties. To assure the absence of residual neurotoxicity, pre-clinical neurovirulence safety testing of candidate vaccines is performed. For mumps virus, a highly neurotropic virus, neurovirulence safety testing is performed in monkeys. However, laboratory studies suggest an inability of this test to correctly discern among virus strains of varying neurovirulence potential in man, and, further, some vaccines found to be neuroattenuated in monkeys were later found to be neurovirulent in humans when administered in large numbers. Over the past decade, concerted efforts have been made to replace monkey-based neurovirulence safety testing with more informative, alternative methods. This review summarizes the current status of mumps vaccine neurovirulence safety testing and insights into models currently approved and those under development. Published by Elsevier Ltd.

Pseudo and conditional score approach to joint analysis of current count and current status data.

Wen, Chi-Chung; Chen, Yi-Hau

2018-04-17

We develop a joint analysis approach for recurrent and nonrecurrent event processes subject to case I interval censorship, which are also known in literature as current count and current status data, respectively. We use a shared frailty to link the recurrent and nonrecurrent event processes, while leaving the distribution of the frailty fully unspecified. Conditional on the frailty, the recurrent event is assumed to follow a nonhomogeneous Poisson process, and the mean function of the recurrent event and the survival function of the nonrecurrent event are assumed to follow some general form of semiparametric transformation models. Estimation of the models is based on the pseudo-likelihood and the conditional score techniques. The resulting estimators for the regression parameters and the unspecified baseline functions are shown to be consistent with rates of square and cubic roots of the sample size, respectively. Asymptotic normality with closed-form asymptotic variance is derived for the estimator of the regression parameters. We apply the proposed method to a fracture-osteoporosis survey data to identify risk factors jointly for fracture and osteoporosis in elders, while accounting for association between the two events within a subject. © 2018, The International Biometric Society.

Efforts continue in compiling tapes which contain vector and scalar data decimated at an interval of 0.5 sec, together with time and position data. A map of the total force field anomaly around Japan was developed which shows a negative magnetic anomaly in the Okhotsk Sea. Examination of vector residuals from the MGST model shows that the total force perturbation is almost ascribable to the perturbation parallel to the main geomagnetic field and that the contribution from the perturbation transverse to the main field to the total force perturbation is negligibly small. The influences of ionospheric current with equatorial electroject and of the magnetospheric field aligned current on the dawn-dusk asymmetry of daily geomagnetic variations are being considered. The total amount of electric current flowing through the plane of the Magsat orbit loop was calculated by direct application of Maxwell's equation. Results show that the total electric current is 1 to 5 ampheres, and the current direction is either sunward or antisunward.

Background: Cruciferous vegetables, a rich source of isothiocyanates, have been reported to lower the risk of several types of cancer, including lung cancer. However, evidence from prospective observations of populations with a relatively high intake of cruciferous vegetables is sparse. Objective: We investigated the association between cruciferous vegetable intake and lung cancer risk in a large-scale population-based prospective study in Japan. Methods: We studied 82,330 participants (38,663 men; 43,667 women) aged 45-74 y without a past history of cancer. Participants were asked to respond to a validated questionnaire that included 138 food items. The association between cruciferous vegetable intake and lung cancer incidence was assessed with the use of Cox proportional hazard regression analysis to estimate HRs and 95% CIs (with adjustments for potential confounding factors). Results: After 14.9 y of follow-up, a total of 1499 participants (1087 men; 412 women) were diagnosed with lung cancer. After deleting early-diagnosed cancer and adjusting for confounding factors, we observed a nonsignificant inverse trend between cruciferous vegetable intake and lung cancer risk in men in the highest compared with the lowest quartiles (multivariate HR: 0.85; 95% CI: 0.69, 1.06; P -trend = 0.13). Stratified analysis by smoking status revealed a significant inverse association between cruciferous vegetable intake and lung cancer risk among those who were never smokers and those who were past smokers after deleting lung cancer cases in the first 3 y of follow-up [multivariate HR for never smokers: 0.49 (95% CI: 0.27, 0.87; P -trend = 0.04); multivariate HR for past smokers: 0.59 (95% CI: 0.35, 0.99; P -trend = 0.10)]. No association was noted in men who were current smokers and women who were never smokers. Conclusion: This study suggests that cruciferous vegetable intake may be associated with a reduction in lung cancer risk among men who are currently nonsmokers. © 2017

A short status update on the LOFAR Epoch of Reionization (EoR) Key Science Project (KSP) is given, regarding data acquisition, data processing and analysis, and current power-spectrum limits on the redshifted 21-cm signal of neutral hydrogen at redshifts z = 8 - 10. With caution, we present a preliminary astrophysical analysis of ~60 hr of processed LOFAR data and their resulting power spectrum, showing that potentially already interesting limits on X-ray heating during the Cosmic Dawn can already be gained. This is by no means the final analysis of this sub-set of data, but illustrates the future potential when all nearly 3000 hr of data in hand on two EoR windows will have been processed.

The aim of this article is to investigate the contemporary teaching of the management of defective direct resin composite restorations in dental schools in Japan. A questionnaire relating to the teaching of the management of defective resin composite restorations was developed and e-mailed to 29 dental schools in Japan in 2010. Completed responses were received from 19 of the 29 invited schools (response rate = 66%). Eighteen schools (95%) report that they included the teaching of repair of direct defective resin composite restorations in their dental school programs. Thirteen schools reported that they included both clinical and didactic instruction on the repair of direct resin composite restorations. Fourteen schools did not teach any mechanical roughening of the exposed resin composite restoration surface before undertaking a repair. The most commonly reported treatment was acid etching with phosphoric acid (12 schools). The most commonly taught material for completing repairs was a flowable resin composite (16 schools). The teaching of repair of defective resin composite restorations is well established within many Japanese dental schools, to a greater extent than in some other regions of the world. The impact of this teaching on subsequent clinical practices in Japan should be investigated. Furthermore, it is concluded that there is a need for much stronger leadership in operative and conservative dentistry, ideally at the global level, to resolve differences in key aspects of operative procedures such as repairs.

Staden, R

1986-01-01

I describe the current status of our sequence analysis software. The package contains a comprehensive suite of programs for managing large shotgun sequencing projects, a program containing 61 functions for analysing single sequences and a program for comparing pairs of sequences for similarity. The programs that have been described before have been improved by the addition of new functions and by being made very much easier to use. The major interactive programs have 125 pages of online help available from within them. Several new programs are described including screen editing of aligned gel readings for shotgun sequencing projects; a method to highlight errors in aligned gel readings, new methods for searching for putative signals in sequences. We use the programs on a VAX computer but the whole package has been rewritten to make it easy to transport it to other machines. I believe the programs will now run on any machine with a FORTRAN77 compiler and sufficient memory. We are currently putting the programs onto an IBM PC XT/AT and another micro running under UNIX.

Healthcare reform as part of the economic recovery plan in Japan is placing emphasis on the use of healthcare information technology (HIT). This research mainly focuses on the HIT efforts in Japan with reference to the US for context. The purpose is to: (a) provide detail on governmental policy impacting promotion of HIT adoption to provide services to the people of Japan, (b) describe the outcomes of past and present policy impacting progress based on a case study of HIT use in the Kyoto Yamashina area, and (c) discuss issues for refinement of current policy. The method is case study, and data collection techniques include: (a) interviews of people involved in policy making for HIT in Japan (Japanese healthcare professionals, government officials, and academics involved in HIT research in Japan) and use in the medical community of HIT in the Kyoto Yamashina area, (b) archived document analysis of reports regarding government policy for HIT policy and user assessment for HIT mainly in the case study site, and (c) the literature review about HIT progression and effectiveness assessments to explore and describe issues concerning the transformation with HIT in Japan. This study reveals the aspects of governmental policy that have been effective in promoting successful HIT initiatives as well as some that have been detriments in Japan to help solve pressing social issues regarding healthcare delivery. For example, Japan has stipulated some standardized protocols and formats for HIT but does not mandate exactly how to engage in inter-organizational or intra-organizational health information exchange. This provides some desired autonomy for healthcare organizations and or governments in medical communities and allows for more advanced organizations to leverage current resources while providing a basis for lesser equipped organizations to use in planning the initiative. The insights gained from the Kyoto Yamashina area initiative reflect the success of past governmental

The purpose of this study was to conduct a descriptive analysis of multiple dimensions of religion with data provided by a nationwide sample of older people in Japan. Six dimensions of religion were evaluated: Religious affiliation, involvement in formal religious organizations, private religious practices, the functions of prayer, belief in punishment by supernatural forces, and beliefs about the afterlife. In addition to describing these facets of religion for the sample as a whole, tests were also performed to see if they vary by age, sex, marital status, education, and whether older Japanese people live in rural or urban areas. The findings suggest that even though older people in Japan are not highly involved in formal religious institutions, they frequently engage in private religious practices. Moreover, the data reveal that while older people in Japan do not often endorse some religious beliefs (e.g., beliefs about the quality of the afterlife), they strongly adhere to others (e.g., beliefs about punishment by supernatural forces). Significant and fairly consistent variations by gender and rural versus urban residence were also observed across the measures of religiousness.

Viral diseases like influenza, AIDS, hepatitis, and Ebola cause severe epidemics worldwide. Along with their resistant strains, new pathogenic viruses continue to be discovered so creating an ongoing need for new antiviral treatments. RNA interference is a cellular gene-silencing phenomenon in which sequence-specific degradation of target mRNA is achieved by means of complementary short interfering RNA (siRNA) molecules. Short interfering RNA technology affords a potential tractable strategy to combat viral pathogenesis because siRNAs are specific, easy to design, and can be directed against multiple strains of a virus by targeting their conserved gene regions. In this review, we briefly summarize the current status of siRNA therapy for representative examples from different virus families. In addition, other aspects like their design, delivery, medical significance, bioinformatics resources, and limitations are also discussed. Copyright © 2018 John Wiley & Sons, Ltd.

Microbiological risk factors in dentistry. Current status of knowledge.

PubMed

Szymańska, Jolanta

2005-01-01

Dentists belong to a professional group potentially exposed to harmful biological factors which most often are infectious microorganisms, less frequently - allergenic or toxic microorganisms. The fundamental routes of spreading harmful microorganisms in a dental surgery are: blood-borne, saliva-droplet, direct contact with a patient and with infected equipment, and water-droplet infections. In this paper, the current status of knowledge on microbiological hazards in a dentist's work is presented. Groups of microorganisms, such as prions, viruses, bacteria, fungi and protozoa, to which a dentist is, or may be exposed, are discussed. Epidemiological assessment of microbiological hazards in a dentist's work was performed and the basic principles of prevention formulated. Special attention was given to microflora in dental unit waterlines, and the biofilm persisting in them, as a source of occupational hazards specific for a dentist's workplace.

Effects of reduced cost-sharing on children's health: Evidence from Japan.

Although childhood health status is widely recognized as an important determinant for future achievement and health, there are few studies on the impact of patient cost-sharing on children's health. This paper investigates whether reduced cost-sharing leads to an improvement of health status among preschool and school-age children in Japan, exploiting regional disparities in expansions of municipality-level subsidy programs for out-of-pocket expenditure. With the eligibility for this subsidy program, known as the Medical Subsidy for Children and Infants (MSCI), the coinsurance rate generally decreases from 30% or 20% to zero for outpatient health care services and drug prescriptions. In order to uncover the impact of this program, I conducted an original survey of all municipalities in Japan to understand the time-series evolution of the eligible age for the MSCI in October 2013 (weighted response rate = 75%), and the probability of being eligible for the MSCI was then calculated by the age, prefecture of residence, and year. These probabilities were matched to children's health data from the Comprehensive Survey of Living Conditions from 1995 to 2010. The results show that eligibility for the MSCI improves subjective measures of health status among preschool children (n = 115,019). However, I find no such improvement among school-age children (n = 133,855). In addition, MSCI eligibility does not reduce hospitalization among either preschool or school-age children. Taken together, this study finds no discernible effects on health among school-age children, suggesting recent rapid expansions of the MSCI for this age group have not been associated with the improvement of health status.

2003-01-01

Japan is known to have an incidence of aneurysmal subarachnoid hemorrhage (SAH) as high as that in Finland, where SAH is especially common. However, the risk factors for SAH in Japan are unknown. The purpose of this study was to identify the risk factors and then examine their possible roles in cases of SAH in Japan. Case-control data were collected in the Aomori prefecture between June 2000 and May 2001 and in the Shimokita area between 1989 and 1998. A history of hypertension, cigarette smoking, alcohol consumption, hypercholesterolemia, and diabetes mellitus were examined as possible risk factors for SAH by using stepwise logistic regression analysis. Stepwise logistic regression analysis showed that a history of hypertension and current smoking increased the risk of SAH and that a history of hypercholesterolemia decreased the risk of SAH. Alcohol consumption and a history of diabetes mellitus were excluded from the model, because their log-likelihood ratios were not significant. The adjusted odds ratios, obtained by forcing matching factors, were 2.29 for a history of hypertension (95% CI, 1.66 to 3.16), 3.12 for current smoking (95% CI, 2.05 to 4.77), and 0.41 for a history of hypercholesterolemia (95% CI, 0.24 to 0.71). The prevalence of hypertension in control subjects was 27% in men and 31% in women, whereas the prevalence of cigarette smoking in control subjects was 46% in men and 9% in women. Hypertension and cigarette smoking seem to be independent risk factors for SAH in Japan. The high prevalence of hypertension in both sexes and the high prevalence of cigarette smoking in men in the general population might contribute to the high incidence of SAH in Japan.

Quantitative analysis of Ostracoda and water masses around Japan: Application to Pliocene and Pleistocene paleoceanography

An ostracode data base consisting of 273 samples from coretops and comprising 226 species was developed for the seas around the Japanese Islands to determine zoogeographic patterns and for application to Pliocene and Pleistocene paleoceanography in the area. Quantitative analyses of the 59 most common taxa between 0 and 300m water depth indicate that ostracode associations are controlled by the main oceanic water masses around Japan and that bottom water temperature is a key factor influencing species distributions. Ostracodes from the following water masses were studied: warm Kuroshio Current, Tsushima Current (Tsugaru Current and Soya Current), Japan Sea intermediate water, Japan Sea proper water and cold Oyashio Current. In order to apply the modem coretop data base to fossil ostracode assemblages, the modem analog technique (MAT) using a squared chord distance (SCD) measure of dissimilarity was tested as a means of comparing fossil and modem assemblages. SCD values of 0.25 or less adequately identify modem analogs from the coretop data set at the local ecological level (i.e. within the same modern bay), while values of 0.25-0.5 identify modem analogs at the level of the zoogeographic province. The MAT method was tested against 3 Pliocene and 11 Pleistocene formations in Japan to examine the use of the MAT in paleoceanographic reconstruction.

One major focus of the current Japanese earthquake prediction research program (2009-2013) is to move toward creating testable earthquake forecast models. For this purpose we started an experiment of forecasting earthquake activity in Japan under the framework of the Collaboratory for the Study of Earthquake Predictability (CSEP) through an international collaboration. We established the CSEP Testing Centre, an infrastructure to encourage researchers to develop testable models for Japan, and to conduct verifiable prospective tests of their model performance. On 1 November in 2009, we started the 1st earthquake forecast testing experiment for the Japan area. We use the unified JMA catalogue compiled by the Japan Meteorological Agency as authorized catalogue. The experiment consists of 12 categories, with 4 testing classes with different time spans (1 day, 3 months, 1 year, and 3 years) and 3 testing regions called All Japan, Mainland, and Kanto. A total of 91 models were submitted to CSEP-Japan, and are evaluated with the CSEP official suite of tests about forecast performance. In this presentation, we show the results of the experiment of the 3-month testing class for 5 rounds. HIST-ETAS7pa, MARFS and RI10K models corresponding to the All Japan, Mainland and Kanto regions showed the best score based on the total log-likelihood. It is also clarified that time dependency of model parameters is no effective factor to pass the CSEP consistency tests for the 3-month testing class in all regions. Especially, spatial distribution in the All Japan region was too difficult to pass consistency test due to multiple events at a bin. Number of target events for a round in the Mainland region tended to be smaller than model's expectation during all rounds, which resulted in rejections of consistency test because of overestimation. In the Kanto region, pass ratios of consistency tests in each model showed more than 80%, which was associated with good balanced forecasting of event

Inequity in physician distribution poses a challenge to many health systems. In Japan, a new postgraduate training program for all new medical graduates was introduced in 2004, and researchers have argued that this program has increased inequalities in physician distribution. We examined the trends in the geographic distribution of pediatricians as well as all physicians from 1996 to 2010 to identify the impact of the launch of the new training program. The Gini coefficient was calculated using municipalities as the study unit within each prefecture to assess whether there were significant changes in the intra-prefectural distribution of all physicians and pediatricians before and after the launch of the new training program. The effect of the new program was quantified by estimating the difference in the slope in the time trend of the Gini coefficients before and after 2004 using a linear change-point regression design. We categorized 47 prefectures in Japan into two groups: 1) predominantly urban and 2) others by the definition from OECD to conduct stratified analyses by urban-rural status. The trends in physician distribution worsened after 2004 for all physicians (p value<.0001) and pediatricians (p value = 0.0057). For all physicians, the trends worsened after 2004 both in predominantly urban prefectures (p value = 0.0012) and others (p value<0.0001), whereas, for pediatricians, the distribution worsened in others (p value = 0.0343), but not in predominantly urban prefectures (p value =0.0584). The intra-prefectural distribution of physicians worsened after the launch of the new training program, which may reflect the impact of the new postgraduate program. In pediatrics, changes in the Gini trend differed significantly before and after the launch of the new training program in others, but not in predominantly urban prefectures. Further observation is needed to explore how this difference in trends affects the health status of the child population.

Endovascular treatments are employed for cerebral vasospasm following subarachnoid hemorrhage, which is not responded to the medical treatments. However, the effect or complication of the treatments is not known well. Here, we analyzed the data of Japanese Registry of Neuroendovascular Therapy 2 (JRNET2) and revealed current status of the endovascular treatment for the cerebral vasospasm. JR-NET2 is conducted from January 1, 2007 to December 31, 2009. Information on the clinical status, imaging studies, treatment methods, the results of treatment, and status 30 days later were recorded. Totally 645 treatments for 480 patients (mean age, 59.4 years; 72.7% woman) were included. Factors related to the neurological improvement and treatment related complications were statistically analyzed. Treatments for ruptured cerebral aneurysm were direct surgery for 366 cases and endovascular treatment for 253 cases. The timing of the endovascular treatment for the cerebral vasospasm was within 3 hours in 209 cases, 3–6 hours in 158 cases, and more than 6 hours in 158 cases. Intra-arterial vasodilator was employed for the 495 cases and percutaneous transluminal angioplasty for 140 cases. Neurological improvement was observed in 372 cases and radiological improvement was seen in 623 cases. The treatment related complication occurred in 20 cases (3.1%), including 6 cases of intracranial hemorrhage, 5 cases of cerebral ischemia, a case of puncture site trouble, and 8 cases of others. Statistical analysis showed early treatment was related to the neurological improvement. Current status of endovascular treatment for cerebral vasospasm was revealed. Endovascular treatment was effective for vasospasm especially was performed early. PMID:24257541

As status of rheumatoid arthritis (RA) is highly affected by environmental factors, a catastrophic disaster may also affect RA activity. Herein we conducted a retrospective cohort study in the disaster area of the 2011 triple disaster in Fukushima, Japan: an earthquake, tsunamis and a nuclear accident. Clinical records of RA patients who attended a hospital near the Fukushima Daiichi Nuclear Power Plant were collected. For those who underwent whole-body counter testing, internal radiation exposure levels were also collected. As clinical parameters may fluctuate in the absence of a disaster, changes in values before and after the disaster were also compared. Logistic regression was conducted to identify factors affecting RA status. Fifty-three patients (average age, 64.2 years; females, 83%; average disease duration, 15.7 years) were included in the study. Five patients lived within the no-entry zone, 37 evacuated immediately after the disaster, and four temporarily stopped RA treatment. The proportions of patients who showed worsened tender joint counts, swollen joint counts and rheumatoid factor values were significantly higher after the disaster compared to those before. Among the 16 patients who underwent whole-body counter testing, only one showed a detectable, but negligible, radioactive cesium level. Use of methotrexate was identified as a possible preventive factor for RA exacerbation in this setting. This is the first study to analyze detailed profiles of RA patients after a disaster. As methotrexate may prevent disease exacerbation, continuity of care for this common chronic disease should be considered in disaster settings. © 2018 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Academic drug discovery: current status and prospects.

PubMed

Everett, Jeremy R

2015-01-01

The contraction in pharmaceutical drug discovery operations in the past decade has been counter-balanced by a significant rise in the number of academic drug discovery groups. In addition, pharmaceutical companies that used to operate in completely independent, vertically integrated operations for drug discovery, are now collaborating more with each other, and with academic groups. We are in a new era of drug discovery. This review provides an overview of the current status of academic drug discovery groups, their achievements and the challenges they face, together with perspectives on ways to achieve improved outcomes. Academic groups have made important contributions to drug discovery, from its earliest days and continue to do so today. However, modern drug discovery and development is exceedingly complex, and has high failure rates, principally because human biology is complex and poorly understood. Academic drug discovery groups need to play to their strengths and not just copy what has gone before. However, there are lessons to be learnt from the experiences of the industrial drug discoverers and four areas are highlighted for attention: i) increased validation of targets; ii) elimination of false hits from high throughput screening (HTS); iii) increasing the quality of molecular probes; and iv) investing in a high-quality informatics infrastructure.

Rickettsioses in Japan and the far East.

PubMed

Mahara, Fumihiko

2006-10-01

Three rickettsial diseases are known to exist in Japan currently: Japanese spotted fever (JSF), Tsutsugamushi disease (TD; scrub typhus), and Q fever. Since April 1999, the system for infection control and prevention in Japan has changed drastically. JSF, Q fever, and TD, as emerging infectious diseases, are designated as national notifiable diseases.The geographic distribution of JSF patients is along the coast of central and southwestern Japan, whereas TD and Q fever occur almost all over the country. The number of JSF patients reported was 216 cases during 1984-1998 and 268 cases, under the revised law, in 1999-2004. About 300-1000 cases of TD occur every year, and 7-46 cases of Q fever in 1999-2004. The number of cases of JSF and its endemic area are gradually increasing. There was only one fatality due to JSF until 2003, whereas two patients died of JSF in 2004, so JSF is still a life-threatening disease in Japan. Treatment of fulminant JSF consists of prompt administration of a combination of tetracycline and quinolone. Recent tick surveys revealed that the most probable vectors of JSF are Haemophysalis flava and Haemophysalis hystericis. In addition to R. japonica, two serotypes or species of spotted fever group rickettsiae have been isolated from ticks in Japan; one is closely related to R. helvetica and the other is a new genotype of unknown genotype AT, which is closely related to a Slovakian genotype. These serotypes are of uncertain clinical significance. Epidemiology of rickettsioses in the Far East is mentioned briefly.

Veterinary therapeutics, based on the art of Materia Medica, has been practised for countless centuries, but the science of veterinary pharmacology is of very recent origin. This review traces the contribution of Materia Medica to veterinary therapeutics from the Egyptian period through to the Age of Enlightenment. The first tentative steps in the development of the science of veterinary pharmacology were taken in the 18th century, but it was not until the mid 20th century that the science replaced the art of Materia Medica. This review traces the 20th century developments in veterinary pharmacology, with emphasis on the explosion of knowledge in the 35 year period to 2010. The range of factors which have influenced the current status of the discipline are reviewed. Future developments are considered from the perspectives of what might be regarded as desirable and those innovations that might be anticipated. We end with words of encouragement for young colleagues intent upon pursuing a career in veterinary pharmacology. © 2013 Blackwell Publishing Ltd.

Ventilator-associated pneumonia (VAP) is a common hazardous complication in ICU patients. The aim of the current review is to give an update on the current status and future recommendations for VAP prevention. This article gives an updated review of the current literature on VAP. The first part briefly reviews pathogenesis and epidemiology while the second includes an in-depth review of evidence-based practice guidelines (EBPG) and new technologies developed for prevention of VAP. VAP remains a frequent and costly complication of critical illness with a pooled relative risk of 9-27% and mortality of 25-50%. Strikingly, VAP adds an estimated cost of more than $40,000 to a typical hospital admission. An important aetiological mechanism of VAP is gross or micro-aspiration of oropharyngeal organisms around the cuff of the endotracheal tube (ETT) into the distal bronchi. Prevention of VAP is preferable. Preventative measures can be divided into two main groups: the implemen- tation of EBPGs and use of device-based technologies. EBPGs have been authored jointly by the American Thoracic Society and the Infectious Diseases Society of America. The Canadian Critical Care Trials group also published VAP Guidelines in 2008. Their recommendations are detailed in this review. The current device-based technologies include drainage of subglottic secretions, silver coated ETTs aiming to influence the internal bio-layer of the ETT, better sealing of the lower airways with ultrathin cuffs and loops for optimal cuff pressure control. EBPG consensus includes: elevation of the head of the bed, use of daily "sedation vacations" and decontamination of the oropharynx. Technological solutions should aim to use the most comprehensive combination of subglottic suction of secretions, optimization of ETT cuff pressure and ultrathin cuffs. VAP is a type of hospital-acquired pneumonia that develops more than 48 h after endotracheal intubation. Its incidence is estimated to be 9-27%, with a

A fact-finding team of American scientists and engineers visited Japan to assess the status of research and development and applications in biodegradable polymers. The visit was sponsored by the National Science Foundation and industry. In Japan, the team met with representatives of 31 universities, government ministries and institutes, companies, and associations. Japan's national program on biodegradable polymers and plastics evaluates new technologies, testing methods, and potential markets for biodegradables. The program is coordinated by the Biodegradable Plastics Society of Japan, which seeks to achieve world leadership in biodegradable polymer technology and identify commercial opportunities for exploiting this technology. The team saw no major new technology breakthroughs. Japanese scientists and engineers are focusing on natural polymers from renewable resources, synthetic polymers, and bacterially-produced polymers such as polyhydroxyalkanoates, poly(amino acids), and polysaccharides. The major polymers receiving attention are the Zeneca PHBV copolymers, Biopol(registered trademark), poly(lactic acid) from several sources, polycaprolactone, and the new synthetic polyester, Bionolle(registered trademark), from Showa High Polymer. In their present state of development, these polymers all have major deficiencies that inhibit their acceptance for large-scale applications.

Objective The aim of this study was to identify the relevant obstetric factors for cerebral palsy (CP) after 33 weeks’ gestation in Japan. Study design This retrospective case cohort study (1:100 cases and controls) used a Japanese national CP registry. Obstetric characteristics and clinical course were compared between CP cases in the Japan Obstetric Compensation System for Cerebral Palsy database and controls in the perinatal database of the Japan Society of Obstetrics and Gynecology born as live singleton infants between 2009 and 2011 with a birth weight ≥ 2,000 g and gestation ≥ 33 weeks. Results One hundred and seventy-five CP cases and 17,475 controls were assessed. Major relevant single factors for CP were placental abnormalities (31%), umbilical cord abnormalities (15%), maternal complications (10%), and neonatal complications (1%). A multivariate regression model demonstrated that obstetric variables associated with CP were acute delivery due to non-reassuring fetal status (relative risk [RR]: 37.182, 95% confidence interval [CI]: 20.028–69.032), uterine rupture (RR: 24.770, 95% CI: 6.006–102.160), placental abruption (RR: 20.891, 95% CI: 11.817–36.934), and preterm labor (RR: 3.153, 95% CI: 2.024–4.911), whereas protective factors were head presentation (RR: 0.199, 95% CI: 0.088–0.450) and elective cesarean section (RR: 0.236, 95% CI: 0.067–0.828). Conclusion CP after 33 weeks’ gestation in the recently reported cases in Japan was strongly associated with acute delivery due to non-reassuring fetal status, uterine rupture, and placental abruption.

On the field-to-current conversion factors for large bipolar lightning discharge events in winter thunderstorms in Japan

Chen, Long; Zhang, Qilin; Hou, Wenhao; Tao, Yulang

In this paper we have simulated the far-field waveform characteristic of large bipolar events (LBEs) occurred in winter thunderstorms in Japan and compared the field-to-current conversion factors (FCCFs) of LBEs with that of the lightning cloud-to-ground (CG) return stroke (RS) in summer thunderstorm. As for the physical process of LBEs, Wu et al. (2014) considered that LBEs may be very similar to the typical lightning RS (RS-like process) or caused by an initial continuous current pulse (ICC-like process) in upward lightning flashes. We assume that the lightning channel length of LBEs ranges from 500 m to 1000 m, and the height of tall object struck by LBEs is from 100 m to 300 m. By using the bouncing wave model, we found that only when the injected current waveform of LBEs is characterized with a symmetric Gaussian pulse, the simulated far-field waveform of LBEs both for RS-like process and ICC-like process is similar to that observed by Wu et al. (2014). For striking tall objects with heights from 100 m and 300 m, the FCCFs of LBEs are positively correlated with its channel length and derivatives of injected current waveform, and the FCCF for RS-like process is about similar to that for ICC-like process. However, the FCCFs of LBEs are very different from lightning RS in summer thunderstorm; that is to say, the FCCFs developed for the well-known lightning RS in summer thunderstorm are not suitable for LBEs.

To assess the true conditions and perceptions of the personal lives of men and women working as surgeons in Japan. In 2014, all e-mail subscribed members of the Japan Surgical Society (JSS, n = 29,861) were invited to complete a web-based survey. The questions covered demographic information, work environment, and personal life (including marital status, childcare, and nursing care for adult family members). In total, 6211 surgeons (5586 men and 625 women) returned the questionnaires, representing a response rate of 20.8%. Based on the questionnaire responses, surgeons generally prioritize work and spend most of their time at work, although women with children prioritize their family over work; men spend significantly fewer hours on domestic work/childcare than do their female counterparts (men 0.76 h/day vs. women 2.93 h/day, p < 0.01); and both men and women surgeons, regardless of their age or whether they have children, place more importance on the role of women in the family. The personal lives of Japanese surgeons differed significantly according to gender and whether they have children. The conservative idea that women should bear primary responsibility for the family still pertains for both men and women working as surgeons in Japan.

Pharmacogenomics (PGx) and biomarkers have been utilized for improving the benefit/risk ratios of drugs and the efficiency of drug development. In the development of drugs for Alzheimer disease (AD), a number of clinical trials have failed to demonstrate clinical efficacy. To overcome this circumstance, the importance of using PGx/biomarkers for enhancing recruitment into clinical trials and for evaluating the efficacy of treatments has been increasingly recognized. In this article, the current status and examples of the use of PGx/biomarkers in Japan for drug development are explained. Guidelines, notifications, and administrative notices related to PGx/biomarkers were downloaded from the Web sites of the Pharmaceuticals and Medical Devices Agency (PMDA), the US Food and Drug Administration, and the European Medicines Agency. Data from clinical studies of AD drugs were obtained from the review reports of the PMDA. To analyze the current status of the use of PGx/biomarkers in Japan, "Issues to Consider in the Clinical Evaluation and Development of Drugs for Alzheimer's Disease (Interim Summary)" was also downloaded from PMDA Web site. There are 2 major measures of utilizing PGx/biomarkers for drug development: (1) biomarker qualification and (2) companion diagnostics. Recently, the PMDA issued a number of guidelines and notifications for their practical use. Although examples of qualified PGx/biomarkers and approved companion diagnostics are limited at present, it is expected that the use of PGx/biomarkers for the development of drugs against AD would increase. For promoting the use of PGx/biomarkers in the development of drugs against AD, PGx/biomarkers should be qualified as early as possible. To that end, accumulating data on PGx/biomarkers from nonclinical or clinical trials and the concurrent development of reliable diagnostics in the early stage of the development process are indispensable. It is important to strengthen collaboration among the academia

This study aimed to investigate longitudinal relations between leisure and social activities and mental health status, considering the presence or absence of other persons in the activity as an additional variable, among middle-aged adults in Japan. This study used nationally representative data in Japan with a five-year follow-up period. This study focused on 16,642 middle-aged adults, age 50-59 at baseline, from a population-based, six-year panel survey conducted by the Japanese Ministry of Health, Labour and Welfare. To investigate the relations between two leisure activities ('hobbies or cultural activities' and 'exercise or sports') and four social activities ('community events', 'support for children', 'support for elderly individuals' and 'other social activities') at baseline and mental health status at follow-up, multiple logistic regression analysis was used. We also used multiple logistic regression analysis to investigate the association between ways of participating in these activities ('by oneself', 'with others', or 'both' (both 'by oneself' and 'with others')) at baseline and mental health status at follow-up. Involvement in both leisure activity categories, but not in social activities, was significantly and positively related to mental health status in both men and women. Furthermore, in men, both 'hobbies or cultural activities' and 'exercise or sports' were significantly related to mental health status only when conducted 'with others'. In women, the effects of 'hobbies or cultural activities' on mental health status were no differences regardless of the ways of participating, while the result of 'exercise or sports' was same as that in men. Leisure activities appear to benefit mental health status among this age group, whereas specific social activities do not. Moreover, participation in leisure activities would be effective especially if others are present. These findings should be useful for preventing the deterioration of mental health

Inhomogeneous cosmology and backreaction: Current status and future prospects

NASA Astrophysics Data System (ADS)

Bolejko, Krzysztof; Korzyński, Mikołaj

Astronomical observations reveal hierarchical structures in the universe, from galaxies, groups of galaxies, clusters and superclusters, to filaments and voids. On the largest scales, it seems that some kind of statistical homogeneity can be observed. As a result, modern cosmological models are based on spatially homogeneous and isotropic solutions of the Einstein equations, and the evolution of the universe is approximated by the Friedmann equations. In parallel to standard homogeneous cosmology, the field of inhomogeneous cosmology and backreaction is being developed. This field investigates whether small scale inhomogeneities via nonlinear effects can backreact and alter the properties of the universe on its largest scales, leading to a non-Friedmannian evolution. This paper presents the current status of inhomogeneous cosmology and backreaction. It also discusses future prospects of the field of inhomogeneous cosmology, which is based on a survey of 50 academics working in the field of inhomogeneous cosmology.

Tick-borne encephalitis (TBE) and severe fever with thrombocytopenia syndrome (SFTS) are both tick-borne zoonotic diseases caused by TBE virus (TBEV) and SFTS phlebovirus (SFTSV). In 2016, a second domestic TBE case was reported in Hokkaido, Japan, after an absence of 23 years. We conducted IgG ELISA for TBEV and SFTSV on 314 deer (Cervus nippon yesoensis) serum samples collected from 3 places in Hokkaido. There were 7 seropositive samples for TBEV but none for SFTSV by ELISA. The specificity of the 7 positive samples was confirmed by neutralization tests against TBEV, and 5 sera showed 320 to 640 of 50% focus reduction endpoint titers. Our results provide information about the infectious status of TBEV in wild deer in Hokkaido, Japan.

Reconsidering Japan's underperformance in pharmaceuticals: evidence from Japan's anticancer drug sector.

PubMed

Umemura, Maki

2010-01-01

Unlike its automobile or electronics industries, Japan's pharmaceutical industry did not become a global leader. Japan remains a net importer of pharmaceuticals and has introduced few global blockbuster drugs. Alfred Chandler argued that Japan's pharmaceutical firms remained relatively weak because Western firms enjoyed an insurmountable first first-mover advantage. However, this case study of the anticancer drug sector illustrates that Chandler's explanation is incomplete. Japanese medical culture, government policy, and research environment also played a substantial role in shaping the industry. In the 1970s and 1980s, these factors encouraged firms to develop little few effective drugs with low side effects, and profit from Japan's domestic market. But, these drugs were unsuitable to foreign markets with more demanding efficacy standards. As a result, Japan not only lost more than a decade in developing ineffective drugs, but also neglected to create the infrastructure necessary to develop innovative drugs and build a stronger pharmaceutical industry.

The purpose of this study was to examine mental health status and related factors among 1st generation Japanese returnees from China and Chinese spouses living in Japan for ten years or more. The subjects were 99 individuals (mean age= 63.9 years), all 1st generation Japanese returnees and their Chinese spouses, living in the Kanto region of Japan. The subjects completed a questionnaire survey, which included items regarding demographics, state of social activity in Japan, self-care behavior, the Tokyo Metropolitan Institute of Gerontology (TMIG) Index of Competence and physical health. The questionnaire survey also incorporated the General Health Questionnaire 12 (GHQ12). The results of the survey were first analyzed by T- and chi2-tests. Logistic regression analysis was then performed in order to identify factors related to the GHQ12. The participants scored high scores on the GHQ12, with 72.7% showing a potential for mental health problems (GHQ12 more than 3). Major complaints were "cannot do useful things" 74.7%, "don't feel happy" 72.7%, "feeling under psychological strain" 59.6%, "unable to make decisions" 57.6%, "feeling depressed" 56.6%, "feeling worried and cannot sleep" 55.5%. The results of the logistic regression analysis revealed that those with potential mental health problems had a higher language barrier (OR: 5.48, 95%CI: 1.52-19.82), fewer providers of health care information (OR: 5.25, 95%CI: 1.32-20.95), fewer voluntary conversations with young people (OR: 3.51, 95%CI: 1.05-11.74), and lower self-rated health (OR: 15.49, 95%CI: 4.11-58.48). In this study, Japanese returnees and their Chinese spouses were found to have mental health problems, significantly associated with a high language barrier, limited information on health care, few conversations with young people, and low self-rated health. Our findings suggest that this population requires immediate assistance to improve their mental health. Furthermore, comprehensive and culturally sensitive
