This paper compares recovery in the wake of three recent earthquakes: the Great East Japan Earthquake in March 2011; the Van earthquake in Turkey in October 2011; and the Maule earthquake in Chile in February 2010. The authors visited all three locations approximately 12-18 months after the incidents and interviewed earthquake specialists, disaster managers, urban planners, and local authorities. A key challenge to post-disaster recovery planning is balancing speed and deliberation. While affected communities must rebuild as quickly as possible, they must also seek to maximise the opportunities for improvement that disasters provide. The three case studies bring this dilemma into stark relief, as recovery was respectively slow, fast, and just right in the aftermath of the events: the Government of Japan adopted a deliberate approach to recovery and reconstruction; speed was of the essence in Turkey; and an effective balance between speed and deliberation was achieved in Chile. © 2017 The Author(s).

We analyzed continuous GPS data to investigate the spatio-temporal distribution of co-seismic slip, post-seismic slip, and largest aftershock associated with the 1994 Sanriku-haruka-oki, Japan, earthquake (Mw = 7.7). To get better resolution for co-seismic and post-seismic slip distribution, we imposed a weak constraint as a priori information of the co-seismic slip determined by seismic wave analyses. We found that the post-seismic slip during 100 days following the main-shock amount to as much moment release as the main-shock, and that the sites of co-seismic slip and post-seismic slip are partitioning on a plate boundary region in complimentary fashion. The major post-seismic slip was triggered by the mainshock in western side of the co-seismic slip, and the extent of the post-seismic slip is almost unchanged with time. It rapidly developed a shear stress concentration ahead of the slip area, and triggered the largest aftershock.

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 purpose of this study was to evaluate the influence of water immersion on the mechanical properties of three kinds of glass fiber posts and the fracture resistance of structures using resin composites with glass fiber posts. Each post was divided into three groups; a control group and two water immersion groups (30 and 90 days). Flexural strength was determined by three-point bending test. Each structure was divided into two groups; a control group and a water immersion group for 30 days. The fracture strength of structures was determined by a static loading test. In the flexural strength, two kinds of post in water immersion groups showed lower values than control groups. In the fracture strength, two kinds of structures in water immersion group showed lower values than control groups. The prefabricated glass fiber posts and structures using resin composites with glass fiber posts were affected by water immersion. Copyright © 2016 Japan Prosthodontic Society.

The Great East Japan Earthquake and subsequent Fukushima nuclear accident triggered citizen dialogue on energy and environmental management in Japan. However, an international survey has shown that the willingness of Japanese citizens to participate in political and social activities has declined since the Fukushima accident. Employing an internet-based survey in four urban or nuclear power plant-hosting prefectures in Japan, this study examines the willingness to participate in random sampling deliberation on post-disaster energy and environmental policy. It focuses on the effects of political, environmental, and social attitudes towards willingness to participate in citizen dialogue. The survey shows around 40% of respondents may participate in energy and environmental deliberation. Statistical analysis reveals that environmental consciousness raises the propensity to participate in deliberation, while political obedience and social hesitation decreases the will to participate. The effect of environmental attitudes is larger than that of political and social attitudes. The survey also finds that governmental response to deliberation, i.e., information generation and disclosure based on requests from citizen dialogue, encourages participation in deliberation in a conservative prefecture, when citizen dialogue is held at the national level. Random sampling deliberation opens a new mode of environmental governance regardless of local political and social characteristics. Copyright © 2017 Elsevier Ltd. All rights reserved.

Long-term immunosuppression is associated with an increased risk of cancer. Especially, the immunosuppression in pancreas transplantation is more intensive than that in other organ transplantation because of its strong immunogenicity. Therefore, it suggests that the risk of post-transplant de novo malignancy might increase in pancreas transplantation. However, there have been few studies of de novo malignancy after pancreas transplantation. The aim of this study was to analyze the incidence of de novo malignancy after pancreas transplantation in Japan. Post-transplant patients with de novo malignancy were surveyed and characterized in Japan. Among 107 cases receiving pancreas transplantation in Japan between 2001 and 2010, de novo malignancy developed in 9 cases (8.4%): post-transplant lymphoproliferative disorders in 6 cases, colon cancer in 1 case, renal cancer in 1 case, and brain tumor in 1 case. We clarified the incidence of de novo malignancy after pancreas transplantation in Japan. Copyright © 2015 Elsevier Inc. All rights reserved.

Japan has the highest frequency of neuraminidase (NA) inhibitor use against influenza in the world. Therefore, Japan could be at high risk of the emergence and spread of NA inhibitor-resistant viruses. The aim of this study was to monitor the emergence of NA inhibitor-resistant viruses and the possibility of human-to-human transmission during four influenza seasons in Japan. To monitor antiviral-resistant A(H1N1)pdm09 viruses, we examined viruses isolated in four seasons from the 2008-2009 season through the 2011-2012 season in Japan by allelic discrimination, NA gene sequencing, and NA inhibitor susceptibility. We found that 157 (1·3%) of 12 026 A(H1N1)pdm09 isolates possessed an H275Y substitution in the NA protein that confers about 400- and 140-fold decreased susceptibility to oseltamivir and peramivir, respectively, compared with 275H wild-type viruses. The detection rate of resistant viruses increased from 1·0% during the pandemic period to 2·0% during the post-pandemic period. The highest detection rate of the resistant viruses was found in patients who were 0-9 years old. Furthermore, among the cases with resistant viruses, the percentage of no known exposure to antiviral drugs increased from 16% during the pandemic period to 44% during the post-pandemic period, implying that suspected human-to-human transmission of the resistant viruses gradually increased in the post-pandemic period. A(H1N1)pdm09 viruses resistant to oseltamivir and peramivir were sporadically detected in Japan, but they did not spread throughout the community. No viruses resistant to zanamivir and laninamivir were detected. © 2013 John Wiley & Sons Ltd.

Antibiotics are the most frequently prescribed medicines for children, however inappropriate antibiotic prescribing is prevalent. This study investigated recent trends in antibiotic use and factors associated with appropriate antibiotic selection among children with group A streptococcal infections in Japan. Records of outpatients aged <18years with a diagnosis of group A streptococcal infection were obtained using the Japan Medical Data Center database. Prescription patterns for antibiotics were investigated and factors associated with penicillin use were evaluated using a multivariable log-binomial regression model. Overall, 5030 patients with a diagnosis of group A streptococcal infection were identified. The most commonly prescribed antibiotics were third-generation cephalosporins (53.3%), followed by penicillins (40.1%). In the multivariable log-binomial regression analysis, out-of-hours visits were independently associated with penicillin prescriptions [prevalence ratio (PR)=1.10, 95% confidence interval (CI) 1.03-1.18], whereas clinical departments other than paediatrics and internal medicine were related to non-penicillin prescriptions (PR=0.57, 95% CI 0.46-0.71). Third-generation cephalosporins were overprescribed for children with group A streptococcal infections. This investigation provides important information for promoting education for physicians and for constructing health policies for appropriate antibiotic prescription. Copyright © 2017.

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

To assess the effect of baby oil on pruritus, sleep quality, and quality of life in hemodialysis (HD) patients. This pretest-post-test model with control groups study was conducted in HD units in two different provinces in eastern Turkey. The study group consisted of a total of 70 patients receiving HD treatment who met the inclusion criteria, 35 being in the intervention group and 35 in the control group. After the patients in both groups were informed about the study, they were administered a questionnaire, the Severity Scale, Visual Analog Scale, the Pittsburgh Sleep Quality Index, and the SF-36 Quality of Life Scale. Following the administration of baby oil to the patients in the intervention group three times a week for a period of 1 month, the same scales were repeated to explore their pruritic status, sleep quality, and quality of life. The same scales were repeated also for the patients in the control group 1 month later but without administering any baby oil. When the Itch Severity Scale, Visual Analog Scale, Pittsburgh Sleep Quality Index, and SF-36 Quality of Life Physical and Mental Component scores of the patients in the control and intervention groups before and after the intervention were compared, the differences in the change were found to be statistically significant in favor of the intervention group (P < 0.05). It was found in this study that administration of baby oil had positive effects on itching, quality of life, and sleep quality in HD patients who had itching complaints. © 2013 The Authors.

The extended use of varicella vaccine in adults aged 50 and older against herpes zoster (HZ) was recently approved in Japan, which has raised the need to evaluate its value for money. We conducted a cost-effectiveness analysis with Markov modelling to evaluate the efficiency of varicella vaccine immunisation programme for the elderly in Japan. Four strategies with different ages to receive a shot of vaccine were set, namely: (1) 65-84, (2) 70-84, (3) 75-84 and (4) 80-84years old (y.o.). Incremental cost-effectiveness ratios (ICERs) compared with no programme from societal perspective were calculated. The health statuses following the target cohort are as follows: without any HZ-related disease, acute HZ followed by recovery, post-herpetic neuralgia (PHN) followed by recovery, post HZ/PHN, and general death. The transition probabilities, utility weights to estimate quality-adjusted life year (QALY) and disease treatment costs were either calculated or cited from literature. Costs of per course of vaccination were assumed at ¥10,000 (US$91). The model with one-year cycle runs until the surviving individual reached 100 y.o. ICERs ranged from ¥2,812,000/US$25,680 to ¥3,644,000/US$33,279 per QALY gained, with 65-84 y.o. strategy having the lowest ICER and 80-84 y.o. strategy the highest. None of the alternatives was strongly dominated by the other, while 80-84 y.o. and 70-84 y.o. strategy were extendedly dominated by 65-84 y.o. Probabilistic sensitivity analyses showed that the probabilities that ICER is under ¥5,000,000/US$45,662 per QALY gained was at 100% for 65-84 y.o., 70-84 y.o., 75-84 y.o. strategy, respectively, and at 98.4% for 80-84 y.o. We found that vaccinating individuals aged 65-84, 70-84, 75-84, and 80-84 with varicella vaccine to prevent HZ-associated disease in Japan can be cost-effective from societal perspective, with 65-84 y.o. strategy as the optimal alternative.

The current paper describes the results of posttraumatic stress educational outreach and screening offered to 141 citizens of Japan who attended a public-service mental health training regarding post-disaster coping 40 days after a 6.8 Richter Scale earthquake, local and regional deaths, and an ongoing nuclear radiation threat. Attendees were given access to anonymous questionnaires that were integrated into the training as a tool to help enhance mental health literacy and bridge communication gaps. Questionnaires were turned in by a third of those in attendance. Among respondents, multiple exposures to potentially-traumatic events were common. More than a quarter of respondents met criteria for probable PTSD. Physical health and loss of sense of community were related to PTSD symptoms. Associations and diagnosis rates represented in these data are not generalizable to the population as a whole or intended for epidemiological purposes; rather, they are evidence of a potentially useful approach to post-disaster clinical screening, education, and engagement. Results are presented in the context of previous findings in Japan and ecologically-supportive post-disaster field research is discussed. PMID:23977819

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

Herpes zoster has a high incidence rate among people aged ≥ 60 years and can lead to serious complications such as post-herpetic neuralgia. There are currently no data on the economic burden of herpes zoster and post-herpetic neuralgia in Japan, and the objective of this study was to address this gap. A total of 412 patients aged ≥ 60 years diagnosed with herpes zoster were recruited. Demographic, clinical, and healthcare resource utilization data on patients with herpes zoster or post-herpetic neuralgia collected via case report forms were used to estimate direct medical cost. Data obtained from a questionnaire survey among patients with herpes zoster/post-herpetic neuralgia were used to estimate transportation cost and productivity loss. The mean number of outpatient visits was 5.7. Prescription medications were the main cost driver accounting for 60% of the direct medical cost. The mean direct medical and total herpes zoster-related costs per patient were ¥43,925 and ¥57,112, respectively, and were higher in patients with post-herpetic neuralgia than in those with herpes zoster without complications. Direct medical cost represented 77%, productivity loss 19%, and transportation cost 4% of the total. This is the first study of the economic burden of herpes zoster and post-herpetic neuralgia in Japan and it demonstrated substantial direct medical cost as a result of the multiple outpatient visits and prescription medications required. These findings provide baseline data for possible future economic evaluations of new herpes zoster/post-herpetic neuralgia interventions. This cost analysis is part of a prospective, physician practice-based cohort study conducted between June 2013 and February 2015 in Kushiro, Japan (Clinicaltrials.gov identifier NCT01873365, registered on 6 June, 2013).

This multicenter, prospective, post-market surveillance study in Japan evaluates the paclitaxel-coated Zilver PTX stent in real-world patients with complex lesions. The Zilver PTX stent is the first drug-eluting stent (DES) approved for the superficial femoral artery. Previously, results from a large randomized study and a complementary, large single-arm study supported the safety and effectiveness of the DES. There were no exclusion criteria, and consecutive patients with symptomatic peripheral artery disease (PAD) treated with the DES were enrolled in the study. Clinically driven target lesion revascularization (TLR) was defined as reintervention performed for ≥50% diameter stenosis after recurrent clinical symptoms of PAD. Clinical benefit was defined as freedom from persistent or worsening symptoms of ischemia. Patency was evaluated by duplex ultrasound where physicians considered this standard of care. In this study, 907 patients were enrolled at 95 institutions in Japan. There were numerous comorbidities including high incidences of diabetes (58.8%), chronic kidney disease (43.8%), and critical limb ischemia (21.5%). Lesions were also complex, with an average length of 14.7 cm, 41.6% total occlusions, and 18.6% in-stent restenosis. In total, 1,861 DES were placed in 1,075 lesions. Twelve-month follow-up was obtained for >95% of eligible patients. Freedom from TLR was 91.0%, and clinical benefit was 87.7% through 12 months. The 12-month primary patency rate was 86.4%. Despite more challenging lesions, results from the current study are similar to outcomes from the previous Zilver PTX studies, confirming the benefit of the Zilver PTX DES in a real-world patient population.

Pre-processing and post-processing in group-cluster mergers

Vijayaraghavan, R.; Ricker, P. M.

2013-11-01

Galaxies in clusters are more likely to be of early type and to have lower star formation rates than galaxies in the field. Recent observations and simulations suggest that cluster galaxies may be `pre-processed' by group or filament environments and that galaxies that fall into a cluster as part of a larger group can stay coherent within the cluster for up to one orbital period (`post-processing'). We investigate these ideas by means of a cosmological N-body simulation and idealized N-body plus hydrodynamics simulations of a group-cluster merger. We find that group environments can contribute significantly to galaxy pre-processing by means of enhanced galaxy-galaxy merger rates, removal of galaxies' hot halo gas by ram pressure stripping and tidal truncation of their galaxies. Tidal distortion of the group during infall does not contribute to pre-processing. Post-processing is also shown to be effective: galaxy-galaxy collisions are enhanced during a group's pericentric passage within a cluster, the merger shock enhances the ram pressure on group and cluster galaxies and an increase in local density during the merger leads to greater galactic tidal truncation.

The aim of this in vitro study was to test the effect of different post systems on fracture strength of roots with re-attached fragments. Root canals of eighty extracted single-rooted human teeth were instrumented (ProFile) and randomly divided into two groups. The roots in the first group were vertically cracked, and the fragments were re-attached using Super Bond C&B (Sun Medical, Tokya, Japan). The roots in the second group were kept sound. Obturation of the roots was performed with MetaSEAL (Sun Medical) and gutta-percha. Post spaces were prepared, and the roots were restored with one of the followings: UniCore (Ultradent), Everstick (Stick Tech), Ribbond (Ribbond), ParaPost (Coltene/Whaledent) (n = 10). Four mm high build-ups were created (Clearfil DC Bond Core; Kuraray, Tokyo, Japan). Compressive loading of the samples was performed after 24 h (1 mm min(-1)). Mean load necessary to fracture each sample was recorded (Newton) and statistically analysed (One-way anova, t-tests). ParaPost showed the highest fracture strength among the roots with re-attached fragments (P < 0.05). UniCore and ParaPost systems showed similar fracture strength in the sound roots (P > 0.05). Re-attached fragments significantly reduced the fracture strength of roots in UniCore group (P = 0.000). Ribbond post showed mostly repairable fractures. Metal post (ParaPost) showed the highest fracture strength in the roots with re-attached fragments; however, fracture pattern was 41% non-repairable. Re-attached fragments significantly reduced the fracture strength of the roots in UniCore group. Prefabricated posts showed similar fracture strength in the sound roots. Customized post systems EverStick and Ribbond showed mostly repairable failure after loading in sound roots or roots with re-attached fragments.

Transfusion is believed to be the main cause of iron overload in Japan. A nationwide survey on post-transfusional iron overload subsequently led to the establishment of guidelines for iron chelation therapy in this country. To date, however, detailed clinical information on the entire iron overload population in Japan has not been fully investigated. In the present study, we obtained and studied detailed clinical information on the iron overload patient population in Japan. Of 1109 iron overload cases, 93.1% were considered to have occurred post-transfusion. There were, however, 76 cases of iron overload of unknown origin, which suggest that many clinicians in Japan may encounter some difficulty in correctly diagnosing and treating iron overload. Further clinical data were obtained for 32 cases of iron overload of unknown origin; median of serum ferritin was 1860.5 ng/mL. As occurs in post-transfusional iron overload, liver dysfunction was found to be as high as 95.7% when serum ferritin levels exceeded 1000 ng/mL in these patients. Gene mutation analysis of the iron metabolism-related genes in 27 cases of iron overload with unknown etiology revealed mutations in the gene coding hemojuvelin, transferrin receptor 2, and ferroportin; this indicates that although rare, hereditary hemochromatosis does occur in Japan.

We performed a nationwide questionnaire-based survey to evaluate the current clinical practices of infectious complications during chemotherapy for acute leukemia in Japan. We e-mailed a questionnaire to member institutions of the Japan Adult Leukemia Study Group in September, 2013. The questionnaire consisted of 50 multiple-choice questions covering therapeutic environment, antimicrobial prophylaxis, screening test during neutropenia, empirical therapy for febrile neutropenia, and the use of granulocyte-colony stimulating factor. The results were compared to those of previous surveys conducted in 2001 and 2007, and also to the recommendations described in the guidelines. Usable responses were received from 141 out of 222 (63.5%) institutions. Chemotherapy for acute myeloid leukemia was performed in protective environment in 90% of the institutions, which increased compared to previous survey (76%). Fluoroquinolones and fluconazole were the most commonly used antimicrobial agents for antibacterial and antifungal prophylaxis, followed by sulfamethoxazole-trimethoprim and itraconazole, respectively. In empirical therapy for febrile neutropenia, monotherapy with β-lactum antibiotics was the first-line therapy in most of the institutions. While empirical antifungal therapy was adopted for persistent fever in more than half of the institutions, preemptive/presumptive therapy was also used in approximately 40% of the institutions. Most of the clinicians were reluctant to use granulocyte-colony stimulating factor routinely in chemotherapy for acute myeloid leukemia. This study clarified the current clinical practices of infectious complications during chemotherapy for acute leukemia and would provide important information for the development of a suitable guideline in Japan.

Killings by juvenile homicide offenders (JHOs) who use accomplices have been increasing since the 1980s and currently represent approximately half of juvenile arrests for murder in the United States. Nevertheless, prior research has not compared JHOs who kill alone with JHOs who kill in groups. The present research followed up 30 years later on a sample of 59 male murderers and attempted murderers sentenced to adult prison. This study was designed to analyze whether lone and group JHOs differed on pre-incarceration, incarceration, and post-incarceration variables. Significant findings indicated that compared with lone offenders, group JHOs had a higher mean of pre-homicide arrests and were more likely to be Black, have a pre-homicide delinquent record, commit a crime-related homicide offense, and target a stranger. With respect to post-homicide variables, group JHOs were more likely to be released from prison and more likely to be rearrested. The two types of JHOs did not differ significantly in relation to the number of post-release violent offenses. Preliminary implications of the findings and avenues for future investigation are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Although psychiatric issues following epilepsy surgery are now widely recognized as a major problem, actual awareness of these issues by epilepsy centers remains to be elucidated. This is the first known report regarding the use of psychiatric assessments and interventions by epilepsy centers throughout Japan. At the beginning of 2016, we sent a questionnaire regarding psychiatric assessments performed before and after epilepsy surgery, psychiatric intervention after surgery, and future plans for dealing with psychiatric issues in relation to epilepsy surgery, which consisted of a total of 24 items, to all members of the Japan Epilepsy Center Association (JEPICA). Nearly all major epilepsy centers in Japan are included in JEPICA, which had 31 members in 2016. Twenty-four (77%) of the 31 centers responded to the questionnaire. Seventeen (70.8%) centers answered that a psychiatrist was incorporated as part of their epilepsy surgery unit. In addition, 17 (70.8%) noted that psychiatric assessments were obtained prior to surgery, which were performed by psychiatrists in 8 (33.3%) centers and psychologists in 11 (45.8%). In 23 (95.8%) of the centers, the risk of occurrence of psychiatric illness following surgery was routinely explained prior to surgery, at least to surgical candidates with high susceptibility. In total, cases of psychiatric illness following surgery had been experienced in 16 (66.7%) centers, with depression as the most commonly encountered (41.7%), followed by anxiety (33.3%), psychosis (25.0%), and psychogenic non-epileptic seizures (8.3%). Strong points of epilepsy centers in Japan include serious concern regarding post-surgical psychiatric illness by nearly all members of JEPICA and explanation of the risk of psychiatric adverse events provided beforehand to their patients. On the other hand, the small size of some epilepsy centers, along with lack of a standardized method for evaluation of psychiatric symptoms as well as dependence on the

In Germany, studies in rehabilitation research--in particular evaluation studies and examinations of quality of outcome--have so far mostly been executed according to the uncontrolled one-group pre-post design. Assessment of outcome is usually made by comparing the pre- and post-treatment means of the outcome variables. The pre-post differences are checked, and in case of significance, the results are increasingly presented in form of effect sizes. For this reason, this contribution presents different effect size indices used for the one-group pre-post design--in spite of fundamental doubts which exist in relation to that design due to its limited internal validity. The numerator concerning all effect size indices of the one-group pre-post design is defined as difference between the pre- and post-treatment means, whereas there are different possibilities and recommendations with regard to the denominator and hence the standard deviation that serves as the basis for standardizing the difference of the means. Used above all are standardization oriented towards the standard deviation of the pre-treatment scores, standardization oriented towards the pooled standard deviation of the pre- and post-treatment scores, and standardization oriented towards the standard deviation of the pre-post differences. Two examples are given to demonstrate that the different modes of calculating effect size indices in the one-group pre-post design may lead to very different outcome patterns. Additionally, it is pointed out that effect sizes from the uncontrolled one-group pre-post design generally tend to be higher than effect sizes from studies conducted with control groups. Finally, the pros and cons of the different effect size indices are discussed and recommendations are given.

In Japan nursing care lags behind the growing population of patients with malignant pleural mesothelioma. This study evaluated an educational program for nurses about caring for patients with malignant pleural mesothelioma in Japan. In this randomized controlled study relative to care for malignant pleural mesothelioma, Knowledge, Difficulties and Attitude were measured at baseline, at post-test and at follow-up one month later. The two-day program with a half-day follow-up program included lectures, group work, role-playing and group discussion. 188 participants were randomly assigned to the intervention group (program, n=96) and control group (n=92; self-study by a similar content handbook). At baseline the groups showed no statistical differences in Knowledge (p=0.921), Difficulty (p=0.458) and Attitude (p=0.922). Completing the study were 177 participants yielding 88 in the intervention group and 89 in the control group. Human rights and privacy of participants were protected. The Knowledge score was significantly higher in the intervention post-test (t=14.03, p=0.000) and follow-up test (t=8.98, p=0.000). Difficulty score was significantly lower in the intervention at post-test (t=-3.41, p=0.001) and follow-up test (t=-3.70, p=0.000). The Attitude score was significantly higher in the intervention post-test (t=7.11, p=0.000) and follow-up test (t=4.54, p=0.000). The two-way analysis of variance with repeated measures on time showed an interaction between time and group; the subsequent simple main effect test found significant differences (p=0.000-0.001) between groups for after-program and at follow-up and a significant difference (p=0.000) in time only within the intervention group. The educational program was effective in improving the nurses' knowledge and attitude toward malignant pleural mesothelioma care and decreasing the difficulty in MPM care, therefore this program has potential for nurses' in-service education throughout Japan.

The aim of this study was to investigate the prevalence of post-traumatic stress disorder (PTSD) and its association with each traumatic experience among 5- to 8-year-old children 2 years after the Great East Japan Earthquake. Children ages 5-8 years who were in selected preschool classes on March 11, 2011, in 3 prefectures affected by the earthquake and 1 prefecture that was unaffected, participated in the study (N=280). PTSD symptoms were assessed through questionnaires completed by caregivers and interviews by psychiatrists or psychologists conducted between September 2012 and May 2013 (ie, 1.5-2 years after the earthquake). Among children who experienced the earthquake, 33.8% exhibited PTSD symptoms. Of the different traumatic experiences, experiencing the earthquake and the loss of distant relatives or friends were independently associated with PTSD symptoms; prevalence ratios: 6.88 (95% confidence interval [CI]: 2.06-23.0) and 2.48 (95% CI: 1.21-5.08), respectively. Approximately 1 in 3 young children in the affected communities exhibited PTSD symptoms, even 2 years after the Great East Japan Earthquake. These data may be useful for preventing PTSD symptoms after natural disasters and suggest the importance of providing appropriate mental health services for children.

Somatoform pain disorder is associated with psychosocial dysfunction, and psychotherapies, such as cognitive behavioral therapy (CBT), are thought to provide useful interventions to address such dysfunction as well as the pain itself. However, little is known about whether CBT for somatoform pain disorder is effective, including the long-term course of the illness, in non-Western populations. We therefore tailored such a program based on an existing CBT protocol and examined its effectiveness in Japan. Thirty-four Japanese participants (22 women; mean age = 52.5 years) enrolled in a weekly 12-session group treatment, with 32 completing both wait-list and treatment conditions. The primary outcome measure was pain intensity. Secondary outcome measures included pain characteristics, as measured by pain catastrophizing and psychometric evaluations, including depression, anxiety, and quality of life. The patients were followed up for 12 months after treatment. We found that pain intensity, anxiety, depressive symptoms, and social functioning all significantly improved after treatment compared with the wait-list period, and the improvements in pain intensity, depressive symptoms, and social functioning were sustained at 12 months following the completion of CBT. There were strong positive correlations (P < 0.01) among pre- and post-treatment changes in the affective dimension of pain, depression, anxiety, and pain catastrophizing. These results show that the present CBT program was effective for Japanese patients with somatoform pain disorder and that gains were maintained over the long term. More work is needed to further clarify the effects of CBT interventions on somatoform symptoms, particularly in Japan. © 2015 The Authors.

We investigated intraspecific diversity and genetic structures of a saprotrophic fungus--Thysanophora penicillioides--based on sequences of nuclear ribosomal internal transcribed spacer (ITS) in 15 discontinuous Abies mariesii forests of Japan. In such a well-defined morphological species, numerous unexpected ITS variations were revealed: 12 ITS sequence types detected in 254 isolates collected from 15 local populations were classified into five ITS sequence groups. Maximally, four ITS groups consisted of seven ITS types coexisting in one population. However, group 1 was dominant with approximately 65%; in particular, one haplotype, 1a, was most dominant with approximately 60% in respective populations. Therefore, few differences were recognized in genetic structure among local populations, implying that the gene flow of each lineage of the fungus occurs among local populations without geographic limitations. However, minor haplotypes in some ITS groups were found only in restricted areas, suggesting that they might expand steadily from their places of origin to neighboring A. mariesii forests. Aggregating sequence data of seven European strains and four North American strains from various substrates to those of Japanese strains, 18 ITS sequence types and 28 variable sites were recognized. They were clustered into nine lineages by phylogenetic analyses of the beta-tubulin and combined ITS and beta-tubulin datasets. According to phylogenetic species recognition by the concordance of genealogies, respective lineages correspond to phylogenetic species. Plural phylogenetic species coexist in a local population in an A. mariesii forest in Japan.

Older maternal age has become more common in Japan. Studies suggest that older maternal age and primiparity are associated with post-partum depression. The present study aimed to identify predictors of post-partum depression in older Japanese primiparas at 1 month post-partum. Participants were 479 primiparas aged 35 years and over, drawn from a prospective cohort study. Data were collected using self-report questionnaires. Depression was measured with the Japanese version of the Edinburgh Postnatal Depression Scale. Stepwise logistic regression analysis was conducted on binary outcome variables of depression at 1 month post-partum, along with a stratified analysis based on the risk status of depression. Five predictors were identified: (i) the depression score during hospital stay; (ii) financial burden; (iii) dissatisfaction with appraisal support; (iv) physical burden in daily life; and (v) concerns about infant caretaking. Stratified analysis identified dissatisfaction with instrumental support in the low-risk group, and the Child-care Value Scale score as unique predictors in the high-risk group. These results highlight the importance of early assessment of depressive symptoms and the provision of continuous care. © 2015 Japan Academy of Nursing Science.

The purpose of this study was to identify the effects of a footbath on post-partum fatigue. This study used a quasi-experimental design by using an unequivalent control group, pre-post-test design. The participants were divided into experimental and control groups. Fifty post-partum women who were admitted to an obstetrics and gynecology ward of a general hospital were the experimental group and 50 post-partum women who were admitted to an obstetrics and gynecology ward of a women's hospital were the control group. Two hospitals were providing similar postnatal care to their patients and they were located in the same city. The experimental group received a footbath along with postnatal care at the hospital, while the control group received only postnatal care from the hospital. Each group completed the Fatigue Continuum Form at a specified time. The general characteristics and pretest dependent variables were homogenous between the two groups. The hypothesis was supported post-test as the Fatigue Continuum Form scores differed significantly between the experimental and the control groups. This study showed that a footbath helps to decrease fatigue among post-partum women. In addition, it is a good preventative strategy for post-partum women who should initiate it in the early post-partum period. © 2016 Japan Academy of Nursing Science.

Decision-makers tend to change the psychological attractiveness of decision alternatives in favor of their own preferred alternative after the decision is made. In two experiments, the present research examined whether such decision consolidation occurs also among individual group members in a large group decision-making situation. High-school students were presented with a decision scenario on an important issue in their school. The final decision was made by in-group authority, out-group authority or by majority after a ballot voting. Results showed that individual members of large groups changed the attractiveness of their preferred alternative from a pre- to a post-decision phase, that these consolidation effects increased when decisions were made by in-group members, and when participants identified strongly with their school. Implications of the findings for understanding of group behavior and subgroup relations are discussed. © 2011 The Authors.

 INTRODUCTION: The purpose of this study was to evaluate external root surface temperature rise during post space preparation using LA Axxess bur, Beefill pack System, and Peeso Reamer drill. MATERIALS AND METHODS: The distal canals of forty-five extracted human permanent mandibular first molars were instrumented in crown-apical manner and obturated with lateral condensation technique. Teeth were then randomly divided into three groups according to post space preparation technique including: group 1. LA Axxess bur (Sybronendo Co., CA, USA), group 2 Beefill pack System (VD W Co., Munich, Germany) and group 3 Peeso Reamer drill (Mani Co., Tochigi-ken, Japan). Temperature was measured by means of digital thermometer MT-405 (Comercio Co., Sao Paulo, Brazil) which was installed on the root surfaces. Data was collected and submitted to one-way ANOVA and Post hoc analysis. RESULTS: Root surface temperatures were found to be significantly higher (7.3±2.7 vs. 4.3±2.1 and 4±2.4,) in samples of Beefill pack System compared with the two other groups (P<0.02). CONCLUSION: Using Beefill pack System during post space preparation may be potentially hazardous for periodontal tissues. PMID:24778690

This project assessed unmet psychosocial needs of kidney transplant recipients and the feasibility of a support group located at an urban Canadian hospital to meet those needs. A survey assessed transplant recipient concerns about psychosocial issues related to transplantation, interest in a support group, desired group composition, facilitation, leadership, barriers and alternative forms of support. Most respondents were more than two years since transplant and were more concerned about medical complications, returning to normalcy, and had a greater desire to talk to other transplant recipients. Forty per cent of respondents indicated they would be interested in a support group. However, 60% indicated that a support group hosted in the hospital setting would be a deterrent to attending, citing time and transportation as the greatest barriers. More research is needed to assess the feasibility of post-kidney transplant support groups closer to recipients' homes and the feasibility of alternative forms of support.

Sorafenib is a multi-kinase inhibitor currently approved in Japan for unresectable and/or metastatic renal cell carcinoma and unresectable hepatocellular carcinoma. Although drug-induced lung injury has recently been the focus of interest in Japanese patients treated with molecular targeting agents, the clinical features of patients receiving sorafenib remain to be completely investigated. All-patient post-marketing surveillance data was obtained within the frame of Special Drug Use Investigation; between April 2008 and March 2011, we summarized the clinical information of 62 cases with drug-induced lung injury among approximately 13,600 sorafenib-treated patients in Japan. In addition, we summarized the results of evaluation by a safety board of Japanese experts in 34 patients in whom pulmonary images were available. For the calculation of reporting frequency, interim results of Special Drug Use Investigation were used. In the sets of completed reports (2,407 in renal cell carcinoma and 647 in hepatocellular carcinoma), the reporting frequency was 0.33 % (8 patients; fatal, 4/8) and 0.62 % (4 patients; fatal, 2/4), respectively. Major clinical symptoms included dyspnea, cough, and fever. Evaluation of the images showed that 18 cases out of 34 patients had a pattern of diffuse alveolar damage. The patients with hepatocellular carcinoma showed a greater incidence and earlier onset of lung injury than those with renal cell carcinoma. Although the overall reporting frequency of sorafenib-induced lung injury is not considered high, the radiological diffuse alveolar damage pattern led to a fatal outcome. Therefore, early recognition of sorafenib-induced lung injury is crucial for physicians and patients.

Post-approval research or monitoring is important to determine real-world safety of new products; however, evidence is scant for vemurafenib in Japanese patients. In Japan, a unique system is officially obligated to investigate post-approval safety. Here we report the first adverse drug reaction (ADR) data from vemurafenib-treated Japanese patients with metastatic melanoma. Data were collected in an early post-marketing phase vigilance (EPPV) study. ADRs were events for which a causal relationship with vemurafenib could not be ruled out or was unknown. ADR data were collected for patients treated with vemurafenib (960 mg bid) between 26 February and 25 August 2015. Among 95 patients, 46 patients had 118 ADRs (24 serious ADRs in 13 patients). The most common serious ADRs were hypersensitivity (n = 1; 3 events), arthralgia (n = 2; 2 events), pyrexia (n = 2; 2 events) and drug eruption (n = 2; 2 events). Seven patients had serious skin disorders or hypersensitivity, six of whom had prior anti-programmed cell death-1 (PD-1) antibodies 5-35 days before starting vemurafenib. ADR reports of serious skin disorders appeared to be collected more rapidly than previously reported. Cutaneous squamous cell carcinoma developed in only one patient. EPPV in Japanese vemurafenib-treated patients identified no new safety signals. The most serious skin and hypersensitivity ADRs occurred in patients with prior anti-PD-1 exposure. Cutaneous squamous cell carcinoma appeared to be rare in Japanese patients. Further research is needed to clarify whether prior treatment with anti-PD-1 agents or racial differences affect the characteristic profile of cutaneous ADRs in Japanese patients.

Post-relational databases provide high performance and are currently widely used in American hospitals. As few hospital information systems (HIS) in either China or Japan are based on post-relational databases, here we introduce a new-generation electronic medical records (EMR) system called Hygeia, which was developed with the post-relational database Caché and the latest platform Ensemble. Utilizing the benefits of a post-relational database, Hygeia is equipped with an "integration" feature that allows all the system users to access data-with a fast response time-anywhere and at anytime. Performance tests of databases in EMR systems were implemented in both China and Japan. First, a comparison test was conducted between a post-relational database, Caché, and a relational database, Oracle, embedded in the EMR systems of a medium-sized first-class hospital in China. Second, a user terminal test was done on the EMR system Izanami, which is based on the identical database Caché and operates efficiently at the Miyazaki University Hospital in Japan. The results proved that the post-relational database Caché works faster than the relational database Oracle and showed perfect performance in the real-time EMR system.

Favorable long-term outcomes of the Zilver PTX drug-eluting stent (DES) in femoropopliteal lesions have been demonstrated. Chronic renal failure (CRF) has been shown to be a risk factor for restenosis and decreased limb salvage. The results of the DES in patients with CRF have not previously been reported. This study compares the results with the DES in patients with CRF and those without CRF. This retrospective analysis from the Zilver PTX Japan Post-Market Surveillance Study included 321 patients with CRF and 584 patients without CRF. Outcomes included freedom from target lesion revascularization (TLR) and patency. Of the patients included in this subgroup analysis, 2-year data were available for 209 patients in the CRF group and 453 patients in the non-CRF group. The two groups were similar in terms of lesion length and the frequency of in-stent restenosis. Critical limb ischemia, severe calcification, and diabetes were more common in patients with CRF, whereas total occlusion was more common in patients without CRF. Freedom from TLR rates were 81.4 versus 84.9% (p = 0.24), and patency rates were 70.7 versus 70.3% (p = 0.95) in patients with and without CRF at 2 years, respectively. This is the first comparative study of the DES in femoropopliteal artery lesions in patients with and without CRF. These results indicate that the DES placed in femoropopliteal artery lesions of CRF patients is safe and effective with similar patency and TLR rates to patients without CRF.

Spontaneous inquiries about the development of adverse drug reactions (ADRs) to medicines can be extracted based on the questions posted by the general public on the electronic Japanese bulletin board "Yahoo! Japan Chiebukuro". Our aim was to clarify the characteristics related to people's descriptions of suspected ADRs and determine the reasons for submitting a spontaneous inquiry. Fifty brand names of medicines used for inquiry extraction were chosen by selecting 35 pharmaceutical products, based on the generic names that had the highest sales in Japan. Questions containing both the brand name of one of these medicines and the term "Fukusayō" (ADR in Japanese) that were posted from July 2004 to June 2009 were extracted from the site. Among 1,419 questions extracted, 614 questions had at least one identifiable brand name of a suspected medicine, an ADR description, and the extent to which the ADR appeared to be caused by the suspected medicine(s). Among these 614 questions, 589 described in detail the symptoms/signs that the inquirers themselves or their families had experienced as ADRs. The highest number of questions was found for Paxil (525). Posts asking whether the symptoms being experienced were due to an ADR accounted for the highest number of questions. In most cases, the inquirer suspected that a single medicine led to an ADR and was seeking advice from others taking the same medicine. Our examination of spontaneous inquiries showed that people have sufficient knowledge to adequately report potential ADRs in terms of their symptoms, suspected medicines, and the disease for which the medicine was used. However, they often did not describe the start time when the ADR appeared or when the suspected medicine was started.

I am to report on some aspects of industrial lasers in Japan. Mostly centering on the market. In Japan, the history of laser developnent is rather profound. And long. Ever since the first invention of the laser in this country in 1960. This is partly because of the fact that in Japan the spectroscopic studies of the ruby was very popular in the late 1950's. Ever since niost of the work has been done in the research laboratories of the industry, not in the universities or not in the governmental laboratories. And since that time our first activity was mainly centering on the basic research, but after that time we have the evolution of the technology. One of the features in Japan is that the activity of developement and research of laser technology from the very basic phase up to the present commercialization has been done by the same group of people, including ine. We had a national project which ended about six years ago which was sponsored by MITI. MITI is Ministry of International Trade and Industry in Japan. And because of this national project, the effect of this project had a very enlightening effect in Japan. And after that our Japanese laser market became very flourishing.

We here describe a new Early Cretaceous (early Albian) eutherian mammal, Sasayamamylos kawaii gen. et sp. nov., from the ‘Lower Formation’ of the Sasayama Group, Hyogo Prefecture, Japan. Sasayamamylos kawaii is characterized by a robust dentary, a distinct angle on the ventral margin of the dentary at the posterior end of the mandibular symphysis, a lower dental formula of 3–4 : 1 : 4 : 3, a robust lower canine, a non-molariform lower ultimate premolar, and a secondarily reduced entoconid on the molars. To date, S. kawaii is the earliest known eutherian mammal possessing only four premolars, which demonstrates that the reduction in the premolar count in eutherians started in the late Early Cretaceous. The occurrence of S. kawaii implies that the relatively rapid diversification of eutherians in the mid-Cretaceous had already started by the early Albian. PMID:23536594

Takashima, Atsuo; Iizumi, Sakura; Boku, Narikazu

2017-07-01

In this review, we focus on post-progression survival after first-line chemotherapy of advanced gastric cancer, and particularly the differences between Japan and the rest of the world. We reviewed 15 recent phase III trials of which 4 were solely recruited from Japanese and 11 from rest of the world. The patient characteristics age, performance status, previous gastrectomy and the number of metastatic sites were similar in Japan and rest of the world. However, the diffuse histological type was more common in Japan. While overall survival was longer in Japan (10.5-14.1 vs. 7.9-12.2 months), progression-free survival tended to be shorter in Japan (3.6-6.0 vs. 3.1-7.4 months). Post-progression survival calculated as the difference between median overall survival and progression-free survival was clearly longer in Japan (6.9-8.6 vs. 2.4-6.2 months). The proportion of patients receiving second-line chemotherapy (%2nd-CX) was quite different in Japan and rest of the world (69-85% vs. 11-59%). Correlations between %2nd-CX and post-progression survival were strong (Spearman's rank correlation coefficient; ρ = 0.86, P < 0.001). Correlations between %2nd-CX and ratio of post-progression survival to total overall survival were also strong (ρ = 0.84, P < 0.001). Because a survival benefit of second-CX was documented in several phase III trials, it can be concluded that higher %2nd-CX partly contributed to extended post-progression survival. However, considering that second-CX increased survival only by ~1.5 months at median, other factors such as third-line chemotherapy may have some influences to prolonged post-progression survival. © The Author 2017.

The activity of Phase I of the Waste Management Working Group under the United States - Japan Joint Nuclear Energy Action Plan started in 2007. The US-Japan JNEAP is a bilateral collaborative framework to support the global implementation of safe, secure, and sustainable, nuclear fuel cycles (referred to in this document as fuel cycles). The Waste Management Working Group was established by strong interest of both parties, which arise from the recognition that development and optimization of waste management and disposal system(s) are central issues of the present and future nuclear fuel cycles. This report summarizes the activity of themore » Waste Management Working Group that focused on consolidation of the existing technical basis between the U.S. and Japan and the joint development of a plan for future collaborative activities. Firstly, the political/regulatory frameworks related to nuclear fuel cycles in both countries were reviewed. The various advanced fuel cycle scenarios that have been considered in both countries were then surveyed and summarized. The working group established the working reference scenario for the future cooperative activity that corresponds to a fuel cycle scenario being considered both in Japan and the U.S. This working scenario involves transitioning from a once-through fuel cycle utilizing light water reactors to a one-pass uranium-plutonium fuel recycle in light water reactors to a combination of light water reactors and fast reactors with plutonium, uranium, and minor actinide recycle, ultimately concluding with multiple recycle passes primarily using fast reactors. Considering the scenario, current and future expected waste streams, treatment and inventory were discussed, and the relevant information was summarized. Second, the waste management/disposal system optimization was discussed. Repository system concepts were reviewed, repository design concepts for the various classifications of nuclear waste were summarized, and the

In 2013, the fifth Tokyo International Conference on African Development (TICAD V) will be hosted by the Japanese government. TICAD, which has been held every five years, has played a catalytic role in African policy dialogue and a leading role in promoting the human security approach (HSA). We review the development of the HSA in the TICAD dialogue on health agendas and recommend TICAD’s role in the integration of the HSA beyond the 2015 agenda. While health was not the main agenda in TICAD I and II, the importance of primary health care, and the development of regional health systems was noted in TICAD III. In 2008, when Japan hosted both the G8 summit and TICAD IV, the Takemi Working Group developed strong momentum for health in Africa. Their policy dialogues on global health in Sub-Saharan Africa incubated several recommendations highlighting HSA and health system strengthening (HSS). HSA is relevant to HSS because it focuses on individuals and communities. It has two mutually reinforcing strategies, a top-down approach by central or local governments (protection) and a bottom-up approach by individuals and communities (empowerment). The “Yokohama Action Plan,” which promotes HSA was welcomed by the TICAD IV member countries. Universal health coverage (UHC) is a major candidate for the post-2015 agenda recommended by the World Health Organization. We expect UHC to provide a more balanced approach between specific disease focus and system-based solutions. Japan’s global health policy is coherent with HSA because human security can be the basis of UHC-compatible HSS. PMID:24155655

Panethnicity revisited: contested group boundaries in the post-9/11 era

PubMed Central

2016-01-01

Existing theories of panethnicity in the USA concentrate on Asian Americans and Latinos, two umbrella groups that originally coalesced during the 1960s civil rights era. Although the role played by the state is recognized as central to panethnic development, we argue that the influence of this pivotal variable is contingent on historical context. Through a case study of emerging minority groups (Middle Eastern and South Asian Americans in the post-9/11 era), we re-examine the existing conceptualization of panethnicity at a time when the state plays a more punitive than compensatory role. Using a methodology that draws on a range of novel sources, we document the way that pre-existing ethnic, religious and national-origin labels have been reinforced instead of panethnic labels for the populations under study. Accordingly, we develop an updated conceptualization of group formation that incorporates historical context and the role of the state in the post-9/11 era. PMID:27182093

[Building epilepsy care network in Japan].

2012-01-01

Number of epilepsy patient in Japan officially surveyed by our government in 2008 is 219,000, which is only 0.17% of the total population and less than one third of the prevalence rate reported in Western countries. Number of epilepsy surgery per year in Japan is also low and less than half of other countries such as US, UK and Korea. These numbers may suggest that epilepsy care in Japan is not sufficient to cover all hidden medical needs of people with epilepsy at present. To solve this issue, our research group funded by the government have started to build an epilepsy care network among primary care physicians, secondary care neurology specialists and tertiary care epilepsy centers by utilizing a web site: Epilepsy Care Network-Japan (http://www.ecn-japan.com/) from July 2012. We are also proposing an epilepsy care algorithm suitable for our complex medical community consisted with various neurology specialists such as pediatric and adult neurologists, neurosurgeons and psychiatrists. Building Epilepsy Care Network in Japan may facilitate better medical and social support for people with epilepsy in Japan.

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.

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 purpose of this study was to examine the application of a group exposure therapy model, the content of which consisted solely of repeated imaginal exposure during sessions, in a clinical sample of female veterans with post-traumatic stress disorder (PTSD). Establishing group delivery of exposure therapy will expand options, increase efficiency, and introduce group curative factors. Eighty-eight female veterans with PTSD completed a six-session exposure group, three participants per group, as a component of a larger treatment program. The PTSD symptom checklist (PCL) was used as the outcome measure and administered in each session. Pre/post-paired t-tests showed significant improvement in PTSD on the PCL, with 40% of completers showing at least a 10-point drop in the PCL scores. In addition, a repeated measures analysis of variance showed a significant main effect and a significant quadratic equation, with expected initial increases in the PCL followed by a decrease below baseline at session 6. The group exposure treatment protocol showed positive outcomes on PTSD symptoms in a real-world clinical sample of female veterans. The implications include an expansion of exposure treatment choices for veterans with PTSD and increased options for therapists.

Emotional eating and eating psychopathology in nonclinical groups: a cross-cultural comparison of women in Japan and the United Kingdom.

PubMed

Waller, G; Matoba, M

1999-11-01

Emotional eating is associated with eating psychopathology among Western populations. It is not known whether the same conclusions hold in non-Western cultures, where norms for emotional expression differ. This study examined whether emotional eating has the same eating psychopathology correlates in different cultures. Three groups of nonclinical women were compared-Japanese living in Japan; Japanese living in the United Kingdom; and British living in the United Kingdom. They completed an Emotional Eating Scale and the Eating Disorders Inventory. There were different patterns of association between emotional eating and eating attitudes in the three groups. British women showed a strong linkage, Japanese women living in Japan showed no association, and Japanese women in the United Kingdom showed an intermediate pattern. Emotional eating may be less of an index of eating psychopathology in non-Western cultures. However, there appears to be an acculturative process, linking the two when one enters a Western culture. This cross-cultural difference may have implications for the targeting of therapies, although this conclusion requires support from further research. Copyright 1999 by John Wiley & Sons, Inc.

Evaluation of rapid post-mortem test kits for bovine spongiform encephalopathy (BSE) screening in Japan: Their analytical sensitivity to atypical BSE prions.

A classical type of bovine spongiform encephalopathy (C-BSE), recognized in 1987, had a large impact on public health due to its zoonotic link to variant Creutzfeldt-Jakob disease by the human consumption of dietary products contaminated with the C-BSE prion. Thus, a number of countries implemented BSE surveillance using rapid post-mortem test kits that were approved for detection of the C-BSE prion in the cattle brain. However, as atypical BSE (L- and H-BSE) cases emerged in subsequent years, the efficacy of the kits for the detection of atypical BSE prions became a matter of concern. In response to this, laboratories in the European Union and Canada evaluated the kits used in their countries. Here, we carried out an evaluation study of NippiBL®, a kit currently used for BSE screening in Japan. By applying the kit to cattle brains of field cases of C-BSE and L-BSE, and an experimental case of H-BSE, we showed its comparable sensitivities to C, L-, and H-BSE prions, and satisfactory performance required by the European Food Safety Authority. In addition to NippiBL®, two kits (TeSeE® and FRELISA®) formerly used in Japan were effective for detection of the L-BSE prion, although the two kits were unable to be tested for the H-BSE prion due to the discontinuation of domestic sales during this study. These results indicate that BSE screening in Japan is as effective as those in other countries, and it is unlikely that cases of atypical BSE have been overlooked.

The Cobalt Chromium Everolimus-Eluting Stent (CoCr-EES) Post Marketing Surveillance (PMS) Japan study is a prospective multicenter registry designed to evaluate the safety and efficacy of XIENCE V/PROMUS everolimus-eluting stents in routine clinical practice at 47 centers representative of the clinical environment in Japan. We enrolled 2010 consecutive patients (2649 lesions) who underwent percutaneous coronary intervention using CoCr-EES. Clinical outcomes were evaluated through 5 years. Mean age was 68.8 years, 41.9% had diabetes, 4.9% received hemodialysis. Five-year clinical follow up was available for 1704 (84.8%) patients. Major adverse cardiovascular events (MACE) occurred in 10.7% of patients, including cardiac death (3.8%), myocardial infarction (1.8%), and clinically driven target lesion revascularization (TLR) (6.0%). Beyond 1 year, annual incidence of clinically driven TLR was 0.5-0.8%. Definite or probable stent thrombosis occurred in 9 (0.5%) patients at 5 years. After 1 year, definite stent thrombosis occurred in only 1 patient. Significant predictors for MACE were dialysis (ODDs ratio 4.58, 95% CI 2.75-7.64), prior cardiac intervention (ODDs ratio 2.47, 95% CI 1.75-3.49), total stent length (ODDs ratio 1.01, 95% CI 1.01-1.02), and number of diseased vessels (ODDs ratio 1.66, 95% CI 1.08-2.55). Five-year clinical outcomes from the CoCr-EES PMS Japan study demonstrated a low incidence of clinical events in the daily practice up to 5 years. https://clinicaltrials.gov/ct2/show/NCT01086228 .

Objectives Survivors of the 2011 Great East Japan Earthquake have an increased risk of depressive symptoms. We sought to examine whether participation in group exercise and regular walking could mitigate the worsening of depressive symptoms among older survivors. Design Prospective observational study. Setting Our baseline survey was conducted in August 2010, ∼7 months prior to the Great East Japan Earthquake and tsunami, among people aged 65 or older residing in Iwanuma City, Japan, which suffered significant damage in the disaster. A 3-year follow-up survey was conducted in 2013. Participants 3567 older survivors responded to the questionnaires predisaster and postdisaster. Primary outcome measures Change in depressive symptoms was assessed using the 15-item Geriatric Depression Scale (GDS). Results From predisaster to postdisaster, the mean change in GDS score increased by 0.1 point (95% CI −0.003 to 0.207). During the same interval, the frequency of group exercise participation and daily walking time also increased by 1.9 days/year and 1.3 min/day, respectively. After adjusting for all covariates, including personal experiences of disaster, we found that increases in the frequency of group exercise participation (B=−0.139, β=−0.049, p=0.003) and daily walking time (B=−0.087, β=−0.034, p=0.054) were associated with lower GDS scores. Interactions between housing damage and changes in group exercise participation (B=0.103, β=0.034, p=0.063) and changes in walking habit (B=0.095, β=0.033, p=0.070) were marginally significant, meaning that the protective effects tended to be attenuated among survivors reporting more extensive housing damage. Conclusions Participation in group exercises or regular walking may mitigate the worsening of depressive symptoms among older survivors who have experienced natural disaster. PMID:28258173

To evaluate the long-term safety and effectiveness of tadalafil in pediatric patients with pulmonary arterial hypertension (PAH) in real-world clinical practice. This is an observational surveillance of PAH patients receiving tadalafil in the contracted sites. A sub-group analysis was performed of 391 pediatric PAH patients (<18 years) who were included from 1,704 total patients in this surveillance. Safety was assessed from the frequency of adverse drug reactions (ADRs), discontinuations due to adverse events (AEs), and serious adverse drug reactions (SADRs). Effectiveness measurements included change in World Health Organization (WHO) functional classification of PAH, cardiac catheterization (pulmonary arterial pressure: PAP), and echocardiography (tricuspid regurgitation pressure gradient: TRPG). Survival rate was also measured. The mean patient age was 5.7 ± 5.34 years. Associated PAH (APAH) and idiopathic PAH (IPAH) accounted for 76.0% and 17.6%, respectively, of the PAH patients. Patients were followed for up to 2 years. Among 391 patients analyzed for safety, the overall incidence rate of ADRs was 16.6%. The common ADRs (≥ 1%) were headache (2.8%), hepatic function abnormal, platelet count decreased (1.3% each), and epistaxis, (1.0%). Eleven patients (2.8%) reported 16 SADRs. Three patients died secondary to SADRs. For the effectiveness analysis, the incidence of WHO functional class improvement at 3 months, 1 year, and 2 years after the initiation of tadalafil and last observation in pediatric patients were 16.5%, 19.7%, and 16.3%, respectively. Both PAP and TRPG showed a statistically significant reduction at last observation. This manuscript reveals the use of tadalafil in the real-world pediatric population with an acceptable safety profile in Japan.

Post-traumatic stress disorder (PTSD) is a common condition among Japanese firefighters. The purpose of this study was to clarify the relationship of PTSD scores to job stress, social support, and depressive stress among Japanese firefighters. A total of 1,667 Japanese firefighters working for the local government completed a questionnaire that was used to gather information pertaining to age, gender, job type, job class, marital status, and smoking and drinking habits. Questionnaires from the Center for Epidemiologic Studies Depression Scale (CES-D), the Japanese version of the U.S. National Institute for Occupational Safety and Health (NIOSH) Generic Job Stress Questionnaire, and the IES-R were also used. After adjustment for age and gender, subjects in the PTSD-positive group had significantly higher scores for inter-group conflict, role ambiguity, and CES-D, as well as significantly lower scores for social support from their supervisors compared to those in the PTSD-negative group. High inter-group conflict and role ambiguity, as well as low social support from supervisors and the presence of depressive symptoms, may influence the development of PTSD among Japanese firefighters.

The efficacy and safety of transcatheter aortic valve implantation (TAVI) in Asian populations were unknown. The purpose of this study was to compare directly the clinical outcomes of the first Japanese trial and a European single-center experience after TAVI. Between April 2010 and October 2011, 64 patients were included in the PREVAIL JAPAN multicenter trial which was set up to evaluate the safety and efficacy of the Edwards SAPIEN XT™ (Edwards Lifesciences, Irvine, CA, USA) in high-risk Japanese patients with severe aortic stenosis. Between March 2010 and January 2012, 237 consecutive patients treated with TAVI using the Edwards SAPIEN XT™ prosthesis at Institut Cardiovasculaire Paris Sud were prospectively included in the Massy cohort. We compared the clinical outcomes of these two cohorts. Patients were of similar age (83.4±6.6 years vs. 84.5±6.1 years, p=0.25), but logistic EuroSCORE was higher in the Massy cohort (20.2±11.7% vs. 15.6±8.0%, p<0.01). Body surface area was smaller in the PREVAIL JAPAN cohort (1.41±0.14m(2) vs. 1.72±0.18m(2); p<0.01) as was the annulus diameter (20.4±1.46mm vs. 22.0±1.84mm, p<0.01). The transfemoral approach was used in 57.8% in the Japanese cohort vs. 51.5% in the Massy cohort. Device success was similar (89.1% vs. 94.1%, p=0.21, respectively), as well as 30-day and 6-month survival rates (92.2% vs. 90.7% and 89.1% vs. 83.1%, p=0.71 and p=0.25, respectively). The incidence of major vascular complications was not significantly different between the two groups (9.4% vs. 5.9%, p=0.23, respectively). A higher post-procedural mean pressure gradient was observed in the PREVAIL JAPAN cohort (12.7±11.4mmHg vs. 10.1±3.6mmHg, p=0.01), but satisfactory improvement in 6-month functional status was obtained in both cohorts (76.5% vs. 77.2%, p=0.91). Clinical outcomes after TAVI in the patients included in the PREVAIL JAPAN trial were acceptable and as safe as that of a single-center European cohort. Copyright © 2014 Japanese

To measure psychiatric symptoms exhibited by children in Ishinomaki City, Japan, an area severely damaged by the 2011 earthquake and tsunami, at 8 and 20 months post-tsunami to investigate differences in symptom severity and recovery rate by age, sex, and degree of trauma experienced. Prospective data were collected from children in elementary school (5th and 6th grades) and junior high school (8th and 9th grades). Students completed the Post-Traumatic Stress Symptoms for Children-15 (PTSSC-15) survey. Trauma severity was scored according to experiences of bereavement, home damage, and evacuation. In total, 3795 PTSSC-15 surveys were analyzed, yielding total scores, post-traumatic stress disorder (PTSD) factor subscores, and depression factor subscores, which were analyzed according to grade group, sex, and degree of trauma (trauma dose). In the elementary school children, mean total PTSSC-15 score, PTSD factor score, and depression factor score were significantly improved at 20 months post-tsunami compared with 8 months (P < .0001 for all), whereas there were no significant improvements in the junior high school children. In females of the older group, the depression factor score at 20 months post-tsunami was significantly higher than at 8 months (P < .01). Elementary school and junior high school children living near the epicenter of the 2011 Japan earthquake and tsunami exhibited marked differences in PTSD and depressive symptoms. The mental health status of elementary school children improved, whereas that of junior high school children did not. Crown Copyright © 2014. Published by Mosby, Inc. All rights reserved.

The purpose of this study was to compare the fracture resistance of Co-Cr post-cores fabricated with 3 different techniques: traditional casting (TC), computer-aided design and manufacturing (CAD/CAM) milling (CCM) and direct metal laser sintering (DMLS). Forty intact human mandibular premolar were endodontically treated. The roots were then randomly divided into four groups according to the post systems: the control group was only filled with gutta percha. Co-Cr metal posts were fabricated with TC, CCM and DMLS in the other three groups. The posts were luted with a resin cement and subjected to compression test at a crosshead speed of 1mm/min. The statistical analysis of the data was performed using one-way analysis of variance (ANOVA) and multiple comparison post hoc Tukey tests (α=.05). The samples were examined under a stereomicroscope with ×20 magnification for the evaluation of the fracture types. The mean fracture loads were 432.69 N for control, 608.89 N for TC, 689.40 N for DMLS and 959.26 N for CCM. One-way ANOVA revealed significant difference between the groups (p<0.01). In the post hoc Tukey test, there were significant differences between groups except DMLS and TC. While Co-Cr posts fabricated by TC and DMLS systems performed similarly in terms of fracture resistance, posts fabricated by CCM techniques showed higher fracture resistance values. Co-Cr metal posts fabricated by CCM and DMLS could be an alternative to TC processing in daily clinical application. Copyright © 2015 Japan Prosthodontic Society. Published by Elsevier Ltd.

The decline in methicillin-resistant Staphylococcus aureus (MRSA) isolation rates has become a general observation worldwide, including Japan. We hypothesized that some genetic shift in MRSA might cause this phenomenon, and therefore we investigated the genetic profiles among MRSA clinical isolates obtained from three different epidemic phases in Japan. A total of 353 MRSA isolates were selected from 202 medical facilities in 1990 (pre-epidemic phase), 2004 (epidemic phase) and 2016 (post-epidemic phase). Molecular typing was performed by PCR detection of 22 genes using the polymerase chain reaction (PCR)-based ORF typing (POT) system, including an additional eight genes including small genomic islets and seven toxin genes. Isolates with a POT1 of score 93, identified as presumed clonal complex (pCC)5-staphylococcal cassette chromosome mec (SCCmec) type II including ST5-SCCmec type II New York/Japan clone, represented the major epidemic MRSA lineage in 1990 and 2004. In 2016, however, a marked decrease in isolates with a POT1 score of 93, along with changes in the epidemiology of toxin genes carried, was noted, where the carriers of tst genes including the tst-sec combination were markedly reduced, and those possessing the seb gene alone were markedly increased. Rather, isolates with a POT1 score of 106, including pCC1 or pCC8 among the isolates with SCCmec type IV, which often links to community-associated MRSA, were predominant. Interestingly, the pCC1 and pCC8 lineages were related to sea and tst-sec carriage, respectively. Over time, a transition in MRSA genetic profiles from a POT1 score of 93 in 1990 and 2004 to 106 in 2014 was found in Japan.

This report outlines the need for the development of an advanced course in mass-casualty life support (MCLS) and introduces the course content. The current problems with education on disasters involving chemical agents, biological agents, radiation/nuclear attacks, or explosives (CBRNE) in Japan are presented. This newly developed "MCLS-CBRNE" program was created by a Ministry of Health, Labour, and Welfare (Tokyo, Japan) research group based on these circumstances. Modifications were then made after a trial course. Training opportunities for relevant organizations to learn how to act at a CBRNE disaster site currently are lacking. The developed course covers initial responses at a disaster site. This one-day training course comprises lectures, three tabletop simulations, and practical exercises in pre-decontamination triage and post-decontamination triage. With regard to field exercises conducted to date, related organizations have experienced difficulties in understanding each other and adapting their approaches. Tabletop simulations provide an opportunity for participants to learn how organizations working on-site, including fire, police, and medical personnel, act with differing goals and guiding principles. This course appears useful as a means for relevant organizations to understand the importance of developing common guidelines. The MCLS-CBRNE training is proposed to support CBRNE disaster control measures during future events. Anan H , Otomo Y , Kondo H , Homma M , Koido Y , Morino K , Oshiro K , Harikae K , Akasaka O .

Gemcitabine was approved for the treatment of biliary tract cancer in 2006 in Japan. While biliary tract cancer is usually associated with patients 70 years of age or older and/or those who tend to have underlying liver dysfunction, data on this population were limited in the Japanese Phase II study of gemcitabine. Thus, further evaluation of safety and effectiveness in this population was planned. This special post-marketing surveillance was conducted as an observational study on the use of gemcitabine in a clinical practice setting. Gemcitabine-naïve patients with biliary tract cancer were enrolled from 2006 to 2008 and observed over 12 months; one or more doses of gemcitabine were administered during the period. Data such as patient background, treatment details, adverse events occurring during the observational period, laboratory values of liver enzyme and survival status were collected 3 and 12 months after the start of therapy. Of the 285 patients registered for the study, 260 were included in the analysis. The mean age was 66.9 years. There were 120 patients (46.2%) classified as elderly (70 years or older). Haematotoxicities were the most common adverse drug reactions. In the elderly and the non-elderly, adverse drug reactions (serious) occurred in 48.3% (20.8%) and 50.7% (12.9%), respectively. The overall estimated 1-year survival rate was 52.5% (95% confidence interval, 45.9-58.7%). In line with previous clinical and post-marketing studies conducted in Japan, the results of this study suggest that gemcitabine could be used safely and effectively for biliary tract cancer patients including the elderly.

[Abortion in Japan].

In Japan, the artificial abortion is a penal offence; only in the presence of certain conditions it is authorized under the provision of the Eugenic Protection Law which was promulgated in 1948. According to the law, the artificial abortion is restricted to the period, in which the fetus is not viable outside of the uterus. This period is prescribed by notification from the Ministry of Public Welfare; up to now it has been shortened twice (1976, 1991). Due to the introduction of economic reasons in the list of conditions and the simplification of the procedure the artificial abortion in Japan was virtually liberalized. Prosecution for illegal abortion is very rare in recent years. The number of reported artificial abortions decreases; in the about last 30 years it reduced by half. However, the increase in the number of abortions in women younger than 20 years of age is a problem. The abortion in teenagers is late compared with that in other age groups. Although the number of neonaticides does not seem to increase, the increase in the number of abortions in teenagers remains a serious problem in Japan.

We investigated trends in early-onset group B streptococcal disease (EOD) after the introduction of culture-based screening in Japan. A retrospective cohort study examined EOD trends in 9506 pregnancies and 10 715 neonates at our center from 2002 to 2009. EOD occurred in four neonates (4/7332: 0.55/1000 live births). The EOD incidence among infants born to women positive for GBS by screening was 0.90 cases per 1000 live births (1/1107). In contrast, the EOD incidence among infants negative by GBS screening was 0.48 cases per 1000 live births (3/6225). Thus, of the four affected neonates, three had mothers who tested negative on antepartum GBS screening. Two neonates had symptoms of infection during labor and intrapartum antibiotic agents were administered. The other two neonates received no antibiotics because deliveries were uneventful and they were negative on GBS screening. The incidence of EOD is 0.90 cases per 1000 live births among GBS-positive women and 0.48 cases per 1000 live births among GBS-negative women. The results of our study implied that EOD can develop regardless of GBS screening and intrapartum clinical course, although the method of sample collection, indications for antibiotic prophylaxis, and the antibiotics regimen should be considered. © 2012 The Authors.

The objective of this article is to evaluate the efficacy and tolerability of two doses of oral sumatriptan vs placebo in the acute treatment of migraine in children and adolescents. Currently, there is no approved prescription medication in Japan for the treatment of migraine in children and adolescents. This was a multicenter, outpatient, single-attack, double-blind, randomized, placebo-controlled, parallel-group study. Eligible patients were children and adolescents aged 10 to 17 years diagnosed with migraine with or without aura (ICHD-II criteria 1.1 or 1.2) from 17 centers. They were randomized to receive sumatriptan 25 mg, 50 mg or placebo (1:1:2). The primary efficacy endpoint was headache relief by two grades on a five-grade scale at two hours post-dose. A total of 178 patients from 17 centers in Japan were enrolled and randomized to an investigational product in double-blind fashion. Of these, 144 patients self-treated a single migraine attack, and all provided a post-dose efficacy assessment and completed the study. The percentage of patients in the full analysis set (FAS) population who report pain relief at two hours post-treatment for the primary endpoint was higher in the placebo group than in the pooled sumatriptan group (38.6% vs 31.1%, 95% CI: -23.02 to 8.04, P  = 0.345). The percentage of patients in the FAS population who reported pain relief at four hours post-dose was higher in the pooled sumatriptan group (63.5%) than in the placebo group (51.4%) but failed to achieve statistical significance ( P  = 0.142). At four hours post-dose, percentages of patients who were pain free or had complete relief of photophobia or phonophobia were numerically higher in the sumatriptan pooled group compared to placebo. Both doses of oral sumatriptan were well tolerated. No adverse events (AEs) were serious or led to study withdrawal. The most common AEs were somnolence in 6% (two patients) in the sumatriptan 25 mg treatment group and chest

The proportion of foreign-born people among the newly notified tuberculosis (TB) patients has been increasing in recent years and potentially poses a new challenge to TB control in Japan. In this report, we analysed the data from the Japan TB surveillance system between 2007 and 2014 to gain an overview of the trends and characteristics of foreign-born TB patients in Japan. We found that the proportion of foreign-born TB patients was especially high among the younger age groups - 44.1% among the 20-29 years age group in 2014. The largest groups of foreign-born patients were from China and the Philippines; however, the number of those from Nepal and Viet Nam was on the rise. Students comprised the second largest professional category group for TB after regular workers, and its proportion increased over the study period. Compared to Japan-born TB patients, foreign-born patients were more likely to be diagnosed through routine medical check-ups. Treatment successes and patients still on treatment were significantly lower among foreign-born patients than their Japan-born counterparts; and transferred-out and unknown outcomes were higher. Our results indicated that distinctive subgroups within the foreign-born population in Japan, especially students and regular workers, might have a higher risk of developing TB. Measures to ensure early diagnosis and treatment adherence should be adapted to such populations.

To evaluate the microleakage along Glassix fibre posts cemented with three different materials. The root canals of maxillary central incisor teeth were filled and restored with Glassix posts (Harald Nordin sa, Chailly/Montreux, Switzerland) cemented with either a zinc-phosphate Harvard cement (Richter & Hoffmann, Harvard Dental GmbH, Berlin, Germany), Fuji PLUS cement (GC Corporation, Tokyo, Japan) or Variolink II cement (Vivadent, Schaan, Lichtenstein) in three groups of 15 canals each. Twenty unrestored canals served as a control group, 10 filled with gutta-percha and sealer (negative control group), the remaining 10 with gutta-percha only (positive control group). Coronal microleakage was evaluated using a fluid transport system. The movement of an air bubble in a capillary glass tube connected to the apex of the experimental root section was measured over 5-min periods. Measurements were performed four times for each specimen and the mean values recorded. ANOVA and Duncan's test were performed. The positive control group had the highest values of microleakage. Amongst experimental groups, the highest values of microleakage occurred in the group with the posts cemented with Harvard cement, followed by Fuji PLUS and Variolink II cements. Groups with Fuji PLUS, Variolink II and the negative control group had significantly (P < 0.00001) less microleakage compared with the Harvard cement group and the positive control group. Canals with Glassix posts cemented with Variolink II and Fuji PLUS cement had the least leakage when assessed using a fluid transport system.

Diffuse large B-cell lymphomas (DLBCL) can be divided into germinal centre (GC-DLBCL) and post germinal centre (post GC-DLBCL) groups by applying immunohistochemical antibodies. As these subgroups respond differently to chemotherapy, it is possible at diagnosis to select a poor prognostic subgroup for aggressive treatment. To determine the frequencies of GC-DLBCL and post GC-DLBCL in patients by immunohistochemistry (IHC) and the clinical response after six cycles of chemotherapy. In this descriptive study conducted in AFIP and CMH, Rawalpindi and NORI, Islamabad, from September 2010 to September 2011, a total of 75 pretreatment cases of DLBCL diagnosed during the study period were included. Cases were segregated in to GC-DLBCL and post GC-DLBCL groups according to results of immunohistochemistry markers CD10, BCL6 and MUM1. Immediate clinical response was assessed after 6 cycles of chemotherapy. Response was divided into complete response, partial response, stable disease or relapse or progression. The mean age was 54.2 ± 15. Males were 53 (70.7%). Forty (53.3%) cases comprised the GC-DLBCL group; 25(62.5%) of them showed a complete response. Most patients of the post GC-DLBCL 19(54%) showed relapse/progression. Results of immediate clinical response in both prognostic subgroups were significant (p<0.05). Results regarding positivity with immunohistochemical antibodies CD10 (p 0.011), BCL6 (p 0.013) and MUM1 (p 0.000) regarding immediate clinical response were also significant. GC-DLBCL group shows better response to CHOP chemotherapy regimen. Immunohistochemistry should be used to further classify DLBCL as this can enable us to select aggressive group for aggressive treatment. This manuscript is important because the study is the first to becarried out exclusively in Pakistan or our part of the world.

The IS015189 "Medical laboratories: Specific requirements regarding quality and competence" is an international standard issued by the International Organization for Standardization (ISO) in February 2003. In October 2004, pilot surveys were initiated in Japan prior to accreditation surveys scheduled to be started in 2005. In September 2005, the first ever ISO15189-accredited facility was established in Japan. With the background of limited information about and few opportunities to study ISO15189 in 2004, we established the Osaka Medical Laboratory ISO15189 Study Group as a unique association that anyone interested in the ISO is able to join. Approximately 900 people have participated in group meetings, which have been held a total of 11 times. Thus, our group has played a major role in ISO development in Japan. To date, approximately 100 facilities have been ISO15189-accredited in Japan, suggesting the need to take new steps regarding its accreditation. As our group has achieved our initial objective, we are planning to work towards taking new steps, such as interaction with accredited facilities.

2012/13 abnormal cold winter in Japan associated with Large-scale Atmospheric Circulation and Local Sea Surface Temperature over the Sea of Japan

On Japan, wintertime cold wave has social, economic, psychological and political impacts because of the lack of atomic power stations in the era of post Fukushima world. The colder winter is the more electricity is needed. Wintertime weather of Japan and its prediction has come under the world spotlight. The winter of 2012/13 in Japan was abnormally cold, and such a cold winter has persisted for 3 years. Wintertime climate of Japan is governed by some dominant modes of the large-scale atmospheric circulations. Yasunaka and Hanawa (2008) demonstrated that the two dominant modes - Arctic Oscillation (AO) and Western Pacific (WP) pattern - account for about 65% of the interannual variation of the wintertime mean surface air temperature of Japan. A negative AO brings about cold winter in Japan. In addition, a negative WP also brings about cold winter in Japan. Looking back to the winter of 2012/13, both the negative AO and negative WP continued from October through December. If the previous studies were correct, it would have been extremely very cold from October through December. In fact, in December, in accordance with previous studies, it was colder than normal. Contrary to the expectation, in October and November, it was, however, warmer than normal. This discrepancy signifies that an additional hidden circumstance that heats Japan overwhelms these large-scale atmospheric circulations that cool Japan. In this study, we therefore seek an additional cause of wintertime climate of Japan particularly focusing 2012 as well as the AO and WP. We found that anomalously warm oceanic temperature surrounding Japan overwhelmed influences of the AO or WP. Unlike the inland climate, the island climate can be strongly influenced by surrounding ocean temperature, suggesting that large-scale atmospheric patterns alone do not determine the climate of islands.

We performed a prenatal diagnosis for 10 fetuses from nine unrelated Japanese xeroderma pigmentosum complementation group A (XP-A) families. All parents had at least one XP-A child (proband) with a homozygous founder mutation (IVS3-1G>C) in the XPA gene. A genetic analysis was performed by a restriction enzyme; AlwNI fragment length polymorphism of polymerase chain reaction (PCR)-amplified DNA, mostly from amniotic fluid (AF) and cultured cells established from AF. However, for the first family, we tried amniocentesis as well as chorionic villus sampling (CVS). Among the 10 cases, we confirmed the results of PCR-based genetic diagnosis by post-ultraviolet survival of amniotic cells in eight cases. Unfortunately, 6 weeks after CVS and 4 days after the amniocentesis in the first case we examined, the fetus died in utero, the reason for which remains unexplained. We prenatally determined two XP-A cases, six XP-A carriers and two wild-type fetuses, which appears to be consistent with Mendel's law. © 2011 Japanese Dermatological Association.

2004-08-01

In the nuclear encoded small subunit ribosomal DNA (18S rDNA) of symbiotic alga of Paramecium bursaria (F36 collected in Japan) possesses three intron-like insertions (Hoshina et al., unpubl. data, 2003). The present study confirmed these exact lengths and insertion sites by reverse transcription-PCR. Two of them were inserted at Escherichia coli 16S rRNA genic position 943 and 1512 that are frequent intron insertion positions, but another insertion position (nearly 1370) was the first finding. Their secondary structures suggested they belong to Group-I intron; one belongs to subgroup IE, others belong to subgroup IC1. Similarity search indicated these introns are ancestral ones.

Nine group B streptococci (GBS) strains were isolated from five toxic shock-like syndrome cases of nonpregnant adults in Japan from 2001 to 2005. All of them were identified as Streptococcus agalactiae. The serotypes of these strains were Ib, III, V, and VII. Pulsed-field gel electrophoresis revealed that the patterns of the strains isolated from the different patients were variable. Antimicrobial susceptibility tests showed that all of the strains were susceptible to penicillin G, ampicillin, cefotaxime, clindamycin, and telithromycin. One strain showed intermediate resistance to erythromycin.

The purposes of this study were to investigate naturalness of the post-treatment speech of Comprehensive Stuttering Program (CSP) clients and differences in naturalness ratings by three listener groups. Listeners were 21 student speech-language pathologists, 9 community members, and 15 listeners who stutter. Listeners rated perceptually fluent speech samples of CSP clients obtained immediately post-treatment (Post) and at 5 years follow-up (F5), and speech samples of matched typically fluent (TF) speakers. A 9-point interval rating scale was used. A 3 (listener group)x2 (time)x2 (speaker) mixed ANOVA was used to test for differences among mean ratings. The difference between CSP Post and F5 mean ratings was statistically significant. The F5 mean rating was within the range reported for typically fluent speakers. Student speech-language pathologists were found to be less critical than community members and listeners who stutter in rating naturalness; however, there were no significant differences in ratings made by community members and listeners who stutter. Results indicate that the naturalness of post-treatment speech of CSP clients improves in the post-treatment period and that it is possible for clients to achieve levels of naturalness that appear to be acceptable to adults who stutter and that are within the range of naturalness ratings given to typically fluent speakers. Readers will be able to (a) summarize key findings of studies that have investigated naturalness ratings, and (b) interpret the naturalness ratings of Comprehensive Stuttering Program speaker samples and the ratings made by the three listener groups in this study.

The goal of this report is to provide an overview of the state of the art of machine translation (MT) in Japan and to provide a comparison between Japanese and Western technology in this area. The term 'machine translation' as used here, includes both the science and technology required for automating the translation of text from one human language to another. Machine translation is viewed in Japan as an important strategic technology that is expected to play a key role in Japan's increasing participation in the world economy. MT is seen in Japan as important both for assimilating information into Japanese as well as for disseminating Japanese information throughout the world. Most of the MT systems now available in Japan are transfer-based systems. The majority of them exploit a case-frame representation of the source text as the basis of the transfer process. There is a gradual movement toward the use of deeper semantic representations, and some groups are beginning to look at interlingua-based systems.

The proportion of foreign-born people among the newly notified tuberculosis (TB) patients has been increasing in recent years and potentially poses a new challenge to TB control in Japan. In this report, we analysed the data from the Japan TB surveillance system between 2007 and 2014 to gain an overview of the trends and characteristics of foreign-born TB patients in Japan. We found that the proportion of foreign-born TB patients was especially high among the younger age groups – 44.1% among the 20–29 years age group in 2014. The largest groups of foreign-born patients were from China and the Philippines; however, the number of those from Nepal and Viet Nam was on the rise. Students comprised the second largest professional category group for TB after regular workers, and its proportion increased over the study period. Compared to Japan-born TB patients, foreign-born patients were more likely to be diagnosed through routine medical check-ups. Treatment successes and patients still on treatment were significantly lower among foreign-born patients than their Japan-born counterparts; and transferred-out and unknown outcomes were higher. Our results indicated that distinctive subgroups within the foreign-born population in Japan, especially students and regular workers, might have a higher risk of developing TB. Measures to ensure early diagnosis and treatment adherence should be adapted to such populations. PMID:27508086

Bacteremia with streptococcus group G is a rare infection, particularly in the post-partum, but of which the incidence has been increasing since the end of the 20th century. The objective of our work is to report the clinical and the bacteriologic aspects, as well as the therapeutic modalities of an exceptional case of bacteremia with streptococcus group G, after a normal vaginal delivery, in a 26-year-old woman. Streptococcus group G being a part of the normal flora of the female genital tract, the endogenous contamination probably took place by passage in the blood circulation during the episiotomy.

2017-07-24

In this study, we conducted a species-level identification of group G streptococcal (GGS) isolates from companion animals in Japan and analyzed antimicrobial resistance (AMR) patterns. Strains were isolated from sterile and non-sterile specimens collected from 72 animals with clinical signs or symptoms in April-May, 2015. We identified the strain by 16S rRNA sequencing, mass spectrometry (MS), and an automated method based on their biochemical properties. Antimicrobial susceptibility was determined using the broth microdilution method and E-test. AMR determinants (erm(A), erm(B), mef(A), tet(M), tet(O), tet(K), tet(L), and tet(S)) in corresponding resistant isolates were amplified by PCR. The 16S rRNA sequencing identified the GGS species as Streptococcus canis (n = 68), Streptococcus dysgalactiae subsp. equisimilis (n = 3), and S. dysgalactiae subsp. dysgalactiae (n = 1). However, there were discrepancies between the sequencing data and both the MS and automated identification data. MS and the automated biochemical technique identified 18 and 37 of the 68 sequencing-identified S. canis strains, respectively. The AMR rates were 20.8% for tetracycline and 5.6% for clarithromycin, with minimum inhibitory concentrations (MIC) 50 -MIC 90 of 2-64 and ≤ 0.12-0.25μg/mL, respectively. AMR genotyping showed single or combined genotypes: erm(B) or tet(M)-tet(O)-tet(S). Our findings show the unique characteristics of GGS isolates from companion animals in Japan in terms of species-level identification and AMR patterns.

To investigate the difficulties Japanese female doctors face in continuing professional practice. A qualitative study using the Kawakita Jiro method. A survey conducted in 2011 of 13 private Japanese medical school alumni associations. 359 female doctors. Barriers of balancing work and gender role. The female doctors reported that professional practice was a struggle with long working hours due to a current shortage of doctors in Japan. There was also a severe shortage of childcare facilities in the workplace. Some women appeared to have low confidence in balancing the physician's job and personal life, resulting in low levels of professional pursuit. There appeared to be two types of stereotypical gender roles, including one expected from society, stating that "child rearing is a woman's job", and the other perceived by the women themselves, that some women had a very strong desire to raise their own children. Male doctors and some female doctors who were single or older were perceived to be less enthusiastic about supporting women who worked while raising children because these coworkers feared that they would have to perform additional work as a result of the women taking long periods of leave. Important factors identified for promoting the continuation of professional practice among female doctors in Japan were the need to improve working conditions, including cutting back on long working hours, a solution to the shortage of nurseries, a need for the introduction of educational interventions to clarify professional responsibilities, and redefinition of the gender division of labour for male and female doctors. In addition, we identified a need to modernise current employment practices by introducing temporary posts to cover maternity leave and introducing flexible working hours during specialist training, thus supporting and encouraging more women to continue their medical careers.

To evaluate 2-year results of the Zilver PTX (Cook Medical, Bloomington, Indiana) drug-eluting stent (DES) for femoropopliteal peripheral artery disease (PAD) in patients with no continuous patent infrapopliteal runoff arteries compared with patients with ≥ 1 continuous patent runoff vessels. A retrospective analysis of patients with femoropopliteal PAD enrolled in the Zilver PTX Post-Market Surveillance Study in Japan was performed. There were no exclusion criteria. Outcomes, including freedom from target lesion revascularization (TLR), patency, and clinical benefit, for the no-runoff group (n = 54) were compared with the runoff group (n = 846). The 2 groups were similar in terms of demographics, lesion characteristics, and comorbidities (P > .05). There was a higher incidence of critical limb ischemia in the no-runoff group compared with the runoff group (44.8% vs 19.7%; P < .01). There were 3 amputations (5.6%) in the no-runoff group versus 7 amputations (0.8%) in the runoff group (P = .02). At 2 years, freedom from TLR rates were 81.3% versus 83.8% (P = .87), patency rates were 68.4% versus 70.7% (P = .95), and clinical benefit rates were 73.7% versus 80.0% (P = .16) in the no-runoff versus runoff group, respectively. Results in patients with no continuous patent tibial runoff were favorable through 2 years and similar to results for patients with ≥ 1 continuous patent runoff vessels, indicating that the Zilver PTX DES may be a valid treatment option for patients with these difficult-to-treat lesions.

To evaluate the safety and efficacy of canagliflozin in elderly patients with type 2 diabetes mellitus (T2DM) in clinical settings. The authors conducted a 1-year post-marketing surveillance (PMS) of canagliflozin in almost all the elderly patients (≥65 years old) with T2DM who began taking canagliflozin during the first 3 months after its launch in Japan. The main outcomes included the incidences of adverse drug reactions (ADRs), serious ADRs, and the changes of laboratory tests as well as efficacy variables. An ADR was reported in 9.09% (125 of 1375 patients) in the safety analysis set. The main ADRs were dehydration, constipation, thirst, pollakiuria, dizziness, cystitis, eczema, pruritus, and rash. The incidence of serious ADRs was 1.02% (14 patients), which included urinary tract infection, dehydration, hypoglycemia, and cerebral infarction (two patients each). ADRs of special interest that had been reported in clinical trials of SGLT2 inhibitors, such as hypoglycemia, volume depletion-related events, genital/urinary tract infection, polyuria/pollakiuria, and ketone body increased were also observed in this PMS. The safety profiles were similar to the results of a previous clinical study of canagliflozin, and new safety concerns were not identified in this survey. The mean change in HbA1c was -0.77% after 12 months of treatment in the efficacy analysis set. In this PMS, the safety and efficacy profiles of canagliflozin in elderly patients with T2DM were obtained in the clinical settings in Japan and the drug was well tolerated and effective in improving glycemic control.

2014-01-01

Stroke is the leading cause of adult disability, with walking impairment being a devastating indicator of chronic post-stroke hemiparesis. Limited resources exist for individual treatments; therefore, the delivery of safe group exercise therapy is highly desired. To examine whether the application of group-based motor imagery practice to community-dwelling individuals with chronic hemiparesis improves gait. Sixteen individuals with chronic hemiparesis from two community centers participated in the study, with eight from each center. Four participants in each center received five weeks of the experimental intervention, consisting of group-based motor imagery exercises of gait tasks, followed by five weeks of control treatment of motor imagery exercises for the affected upper extremity. Four other subjects in each center received the same treatments in reverse order. Pre- and post intervention measurements included clinical and biomechanical gait parameters. Comparisons within (pre- vs. post) and between treatments (experimental vs. control) indicated no significant change in any gait variable. Nevertheless, the verbal reports of most participants alluded to satisfaction with the experimental intervention and to an increase in self-confidence. Despite the lack of evidence for the effectiveness of group-based motor imagery practice in improving gait among individuals with chronic hemiparesis, the contrast between the measured outcomes and the positive verbal reports merits further inquiry.

Neonatal encephalopathy (NE) secondary to intrapartum asphyxia remains a major cause of post-natal death and permanent neurological deficits worldwide. Supportive therapy has been the mainstay of the treatment until recent series of large clinical trials demonstrating benefit of therapeutic hypothermia (TH) in this high risk population. Now the International Liaison Committee on Resuscitation (ILCOR) recommends TH as a standard of care with the protocols used in the large clinical trials as tentative standard protocols. Our goal is to develop a nationwide consensus practice guideline not only consistent with the international standard protocols but also practical and compatible with the current medical system in Japan. In summary, TH should be offered to newborn infants born ≥36 weeks gestational age and birth weight ≥1800 g exhibiting clinical signs of moderate to severe NE as well as evidence of hypoxia-ischemia, i.e. 10 min Apgar score ≤5, a need for resuscitation at 10 min, blood pH<7.00, or base deficit ≥16 mmol/L. TH should be conducted in the NICUs capable of multidisciplinary care and under the standard protocols, i.e. utilization of cooling device, target (rectal or esophageal) temperatures at 33.5±0.5 and 34.5±0.5°C for whole body and selective head cooling respectively, duration of TH for 72 h, gradual rewarming not exceeding the rate of 0.5°C/h. Long term follow-up with multidisciplinary approach including standardized psychological assessment is warranted. Copyright © 2011 The Japanese Society of Child Neurology. Published by Elsevier B.V.

In September 2016, 140 patients with primary symptoms of sore throat and fever were identified in a school dormitory in Osaka, Japan. Epidemiological and laboratory investigations determined that these symptomatic conditions were from a foodborne outbreak of group G streptococcus (GGS), with GGS being isolated from samples from patients, cooks, and foods. The strain of GGS was identified as Streptococcus dysgalactiae subsp. equisimilis of two emm types ( stG652.0 and stC36.0 ). The causative food, a broccoli salad, was contaminated with the two types of S. dysgalactiae subsp. equisimilis , totaling 1.3 × 10 4 CFU/g. Pulsed-field gel electrophoresis (PFGE) of samples from patients, cooks, and foods produced similar band patterns among samples with the same emm type. This result suggested the possibility of exposure from the contaminated food. The average onset time was 44.9 h and the prevalence rate was 62%. This is the first report to identify the causative food of a foodborne outbreak by Streptococcus dysgalactiae subsp. equisimilis . Copyright © 2018 American Society for Microbiology.

The number of older primiparas is increasing in Japan. These women have been shown to be more vulnerable to post-partum depression. This study aimed to identify factors for predicting post-partum depressive symptoms during hospitalization after childbirth in Japanese primiparas aged 35 years and over. The present authors used the data of 479 primiparas aged 35 years and over from a prospective cohort study. Data were collected using self-report questionnaires on the day before hospital discharge. The questionnaire consisted of: demographics and background information; depressive symptoms; fatigue; maternal confidence and maternal satisfaction; child-care values; physical symptoms; perceptions of daily life during hospitalization; concerns about child care and daily life; and infant feeding. Additionally, vital records data were obtained from the hospitals. A stepwise logistic regression analysis was performed on the binary outcome variable of depressive symptoms, measured by the Japanese version of the Edinburgh Postnatal Depression Scale. Women who scored 9 or more were considered to be at high risk for post-partum depression. The authors obtained informed consent from all participants and institutional ethics approvals before initiating the study. The following six variables reliably predicted the risk of post-partum depression: emergency cesarean section, lower satisfaction with birth experience, higher physical burden in daily life, long-term complications with the newborn, more concerns about newborn caretaking after discharge, and more concerns about one's own life after discharge. Recognition of women with these factors will help nurses to identify those at risk for developing post-partum depression and to provide appropriate care during hospitalization after childbirth. © 2015 The Authors.

Streptococcal toxic shock syndrome (STSS) is a severe invasive infection characterized by the sudden onset of shock, multi-organ failure, and high mortality. In Japan, appropriate notification measures based on the Infectious Disease Control law are mandatory for cases of STSS caused by β-haemolytic streptococcus. STSS is mainly caused by group A streptococcus (GAS). Although an average of 60-70 cases of GAS-induced STSS are reported annually, 143 cases were recorded in 2011. To determine the reason behind this marked increase, we characterized the emm genotype of 249 GAS isolates from STSS patients in Japan from 2010 to 2012 and performed antimicrobial susceptibility testing. The predominant genotype was found to be emm1, followed by emm89, emm12, emm28, emm3, and emm90. These six genotypes constituted more than 90% of the STSS isolates. The number of emm1, emm89, emm12, and emm28 isolates increased concomitantly with the increase in the total number of STSS cases. In particular, the number of mefA-positive emm1 isolates has escalated since 2011. Thus, the increase in the incidence of STSS can be attributed to an increase in the number of cases associated with specific genotypes.

This paper provides a framework for evaluating the effects of population ageing on disaster resilience. In so doing, it focuses on the 1995 Kobe and 2004 Chuetsu earthquakes, two major disasters that affected Japan before the 2011 Great East Japan earthquake. It analyses regional population recovery on the basis of pre-disaster and post-recovery demographic characteristics using defined transition patterns of population ageing. The evaluation framework demonstrates that various recovery measures make different contributions to disaster resilience for each transition pattern of population ageing. With reference to regional population ageing, the framework allows for a prediction of disaster resilience, facilitating place vulnerability assessments and potentially informing policy-making strategies for Japan and other countries with ageing populations. © 2014 The Author(s).

Post-traumatic growth (PTG) refers to positive changes that result from coping with a major life crisis or a traumatic event. Factors influencing PTG in youth have not been well characterized but could have a great impact on overall maturation. Fourth to ninth graders (n = 3337) attending elementary or junior high schools located in a district severely damaged by the Great East Japan Earthquake completed a questionnaire, including the revised Posttraumatic Growth Inventory for Children (PTGI-C-R) along with the Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), 31 months after the event. Experience of the disaster, prior traumatic experiences, and attitudes toward memories of the disaster (rumination) were scored by their caregivers and teachers, and effects of these factors on PTG were evaluated. There were no significant associations between PTGI-C-R and sex or experiences of the disaster. However, PTGI-C-R was negatively correlated with age (r = -0.132, P < 0.001). There was significant but very weak negative correlation between PTGI-C-R and PTSSC-15 among the children (r = -0.096, P < 0.001). PTGI-C-R was significantly associated with positive attitudes to memorial services (P < 0.001) and media coverage (P < 0.05). Positive attitudes to deliberate rumination may facilitate PTG in children following natural disasters. © 2016 The Authors.

In Japan, all trainee physicians must begin clinical practice in a standardized, mandatory junior residency program, which encompasses the first two years of post-graduate medical training (PGY1 - PGY2). Implemented in 2004 to foster primary care skills, the comprehensive rotation program (CRP) requires junior residents to spend 14 months rotating through a comprehensive array of clinical departments including internal medicine, surgery, anesthesiology, obstetrics-gynecology (OBGYN), pediatrics, psychiatry, and rural medicine. In 2010, Japan's health ministry relaxed this curricular requirement, allowing training programs to offer a limited rotation program (LRP), in which core departments constitute 10 months of training, with electives geared towards residents' choice of career specialty comprising the remaining 14 months. The effectiveness of primary care skill acquisition during early training warrants evaluation. This study assesses self-reported confidence with clinical competencies, as well as case experience, between residents in CRP versus LRP curricula. A nation-wide cross-sectional study of all PGY2 physicians in Japan was conducted in March 2011. Primary outcomes were self-report confidence for 98 clinical competency items, and number of cases experienced for 85 common diseases. We compared confidence scores and case experience between residents in CRP and LRP programs, adjusting for parameters relevant to training. Among 7506 PGY2 residents, 5052 replied to the survey (67.3%). Of 98 clinical competency items, CRP residents reported higher confidence in 12 items compared to those in an LRP curriculum, 10 of which remained significantly higher after adjustment. CRP trainees reported lower confidence scores in none of the items. Out of 85 diseases, LRP residents reported less experience with 11 diseases. CRP trainees reported lower case experience with one disease, though this did not remain significant on adjusted analysis. Confidence and case experience

Tardigrade research in Japan dates back over 100 years, and to date, 167 species of this ecdysozoan phylum have been reported from the country. Of these species, the Macrobiotus hufelandi complex has been represented only by the nominal taxon of this group, Macrobiotus hufelandi. In this article, a new species of the hufelandi group from Japan, Macrobiotus shonaicus sp. nov., is described using integrative taxonomy. In addition to the detailed morphological and morphometric data, obtained using phase contrast light microscopy (PCM) and scanning electron microscopy (SEM), we provide DNA sequences of four molecular markers (both nuclear and mitochondrial). The new species belongs to the persimilis subgroup and is most similar to M. anemone from USA, M. naskreckii from Mozambique, and M. patagonicus from Argentina, but it can be easily distinguished from these species by the presence of thin flexible filaments on terminal discs of the egg process. By the latter character, the new species is most similar to M. paulinae and M. polypiformis, but it can be easily distinguished from them by having a solid egg surface between egg processes (i.e., without pores or reticulum). A phylogenetic analysis of available DNA sequences of the COI marker for the hufelandi group revealed that the new species clusters with the two other species that exhibit filaments on egg process discs (M. paulinae and M. polypiformis) and with two species that have entire egg processes modified into filaments (M. kristenseni and M. scoticus). All five species form a clade distinct from all other sequenced species of the hufelandi group with typical mushroom- or inverted goblet-shaped egg processes, which may suggest that the ancestor of the five species with atypical egg processes had a mutation allowing derivations from the mushroom or inverted chalice-like shape of egg processes.

Background Social anxiety disorder (SAD) is one of the most common psychiatric disorders worldwide. Cognitive behavioral therapy (CBT) is an effective treatment option for patients with SAD. In the present study, we examined the efficacy of group CBT for patients with generalized SAD in Japan at 1-year follow-up and investigated predictors with regard to outcomes. Methods This study was conducted as a single-arm, naturalistic, follow-up study in a routine Japanese clinical setting. A total of 113 outpatients with generalized SAD participated in group CBT from July 2003 to August 2010 and were assessed at follow-ups for up to 1 year. Primary outcome was the total score on the Social Phobia Scale/Social Interaction Anxiety Scale (SPS/SIAS) at 1 year. Possible baseline predictors were investigated using mixed-model analyses. Results Among the 113 patients, 70 completed the assessment at the 1-year follow-up. The SPS/SIAS scores showed significant improvement throughout the follow-ups for up to 1 year. The effect sizes of SPS/SIAS at the 1-year follow-up were 0.68 (95% confidence interval 0.41–0.95)/0.76 (0.49–1.03) in the intention-to-treat group and 0.77 (0.42–1.10)/0.84 (0.49–1.18) in completers. Older age at baseline, late onset, and lower severity of SAD were significantly associated with good outcomes as a result of mixed-model analyses. Conclusions CBT for patients with generalized SAD in Japan is effective for up to 1 year after treatment. The effect sizes were as large as those in previous studies conducted in Western countries. Older age at baseline, late onset, and lower severity of SAD were predictors for a good outcome from group CBT. PMID:23450841

The ‘abnormal’ state: Identity, norm/exception and Japan

PubMed Central

2015-01-01

The term ‘abnormal’ has frequently been used to describe post-war Japan. Together with the idea that the country will, or should have to, ‘normalise’ its foreign and security policy, it has been reproduced in both academia and Japanese society. Why is Japan branded as ‘abnormal’, and from where does the desire to ‘normalise’ it come? Drawing on a relational concept of identity, and the distinction between norm and exception, this article argues that the ‘abnormality–normalisation nexus’ can be understood in terms of three identity-producing processes: (1) the process whereby the Japanese Self is socialised in US/‘Western’ norms, ultimately constructing it as an Other in the international system; (2) the process whereby the Japanese Self imagines itself as ‘legitimately exceptional’ (what is called ‘exceptionalisation’), but also ‘illegitimately abnormal’ — both of which are epitomised by Japan’s ‘pacifism’; and (3) the process whereby both the Self’s ‘negative abnormality’ and China/Asia are securitised in attempts to realise a more ‘normal’ (or super-normal) Japanese Self. How Japan is inter subjectively constructed on a scale between ‘normal’ and ‘abnormal’ enables and constrains action. Although Japan has not remilitarised nearly as much in the 2000s as is often claimed, these processes might very well forebode an exceptional decision to become ‘normal’ and therefore more significant steps towards remilitarisation.

In situ seismic anisotropy around deep earthquakes in Japan subduction slabs using Japan Meteorological Agency moment tensors

Li, J.; Zheng, Y.; Thomsen, L.

2017-12-01

Knowing the in situ seismic anisotropy around deep earthquakes in slabs is important in understanding deep-earthquake mechanism as it may provide critically needed information about the rock fabric where deep earthquakes occur. It has been recognized for about 50 years that many deep earthquakes are not double-couple (DC) events. Previously we showed that in situ anisotropy around deep earthquakes could explain such observed non-DC events. Traditionally, the shear wave splitting method has been used to infer such anisotropy around deep earthquakes but this is challenging because it will need many crossing ray paths for the method to localize the anisotropic region (Long 2013). In this abstract, we adopt the same procedure to obtain anisotropy in the Pacific slab under Japan using moment tensors provided by the Japan Meteorological Agency using the F-net data. We directly probe the in situ anisotropy within the subducting slabs using the radiation patterns (represented by the moment tensors) of deep earthquakes (with depth greater than 60 km). By assuming a group of shear dislocation events embedded in a common tilted transversely isotropic (TTI) medium, we used the moment tensors as our input data to invert for the anisotropy in Mariana-Japan-Kuril subducting zone. The TTI medium is characterized by the P and S wave velocities along the symmetry axis (described by two free angles) and three Thomsen parameters. We divided the deep earthquake events into 9 groups by their spatial proximity using the k-means clustering method (Hartigan and Wong 1979). These 9 groups include 2 intermediate-depth groups (depth from 60 km to 300 km) and 7 deep-focus groups (depth greater than 300 km). Our inversion results show that the inverted TTI symmetry axes are perpendicular to the slab interface for two intermediate-depth groups (consistent with dehydration metamorphic reactions) and parallel to the slab interface for 7 deep-focus group. The shear wave anisotropy is best resolved

A magnitude 9.0 earthquake struck off eastern Japan in March 2011. Many survivors have been living in temporary houses provided by the local government since they lost their houses as a result of the great tsunami (tsunami group) or the expected high-dose radiation resulting from the nuclear accident at the Fukushima Daiichi Nuclear Power Plant (radiation group). The tsunami was more than 9 m high in Soma, Fukushima, which is located 30 km north of the Fukushima Daiichi Nuclear Power Plant and adjacent to the mandatory evacuation area. A health screening program was held for the evacuees in Soma in September 2011. The aim of this study was to compare the metabolic profiles of the evacuees before and after the disaster. We hypothesized that the evacuees would experience deteriorated metabolic status based on previous reports of natural disasters. Data on 200 subjects who attended a health screening program in September or October of 2010 (pre-quake) and 2011 (post-quake) were retrospectively reviewed and included in this study. Pre-quake and post-quake results of physical examinations and laboratory tests were compared in the tsunami and radiation groups. A multivariate regression model was used to determine pre-quake predictive factors for elevation of hemoglobin A1c (HbA1c) in the tsunami group. Significantly higher values of body weight, body mass index, waist circumference, and HbA1c and lower high-density lipoprotein cholesterol levels were found at the post-quake screening when compared with the pre-quake levels (p = 0.004, p = 0.03, p = 0.008, p < 0.001, and p = 0.03, respectively). A significantly higher proportion of subjects in the tsunami group with high HbA1c, defined as ≥ 5.7%, was observed after the quake (34.3%) than before the quake (14.8%) (p < 0.001). Regional factors, periodic clinic visits, and waist circumference before the quake were identified as predictive factors on multivariate analysis for the deterioration of HbA1c. Post-quake metabolic

The objective of this article is to review community-based drug abuse prevention and relapse prevention in Japan. Japan has a highly efficient system for the primary prevention of drug abuse; this system includes drug abuse education programs in schools and anti-drug abuse campaigns in communities. On the other hand, relapse prevention activities, such as counseling service at mental health welfare centers, self-help groups for drug addicts, and relapse prevention programs at outpatient clinics, are limited because of zero tolerance policies. Therefore, more relapse prevention activities are required in Japanese communities.

Differences in mineral concentrations were examined among three types of wine in the Japanese market place: Japan wine, imported wine, and domestically produced wine mainly from foreign ingredients (DWF), where Japan wine has been recently defined by the National Tax Agency as domestically produced wine from grapes cultivated in Japan. The main objective of this study was to examine the possibility of controlling the authenticity of Japan wine. The concentrations of 18 minerals (Li, B, Na, Mg, Si, P, S, K, Ca, Mn, Co, Ni, Ga, Rb, Sr, Mo, Ba, and Pb) in 214 wine samples were determined by inductively coupled-plasma mass spectrometry (ICP-MS) and ICP-atomic emission spectrometry (ICP-AES). In general, Japan wine had a higher concentration of potassium and lower concentrations of eight elements (Li, B, Na, Si, S, Co, Sr, and Pb) as compared with the other two groups of wine. Linear discriminant analysis (LDA) models based on concentrations of the 18 minerals facilitated the identification of three wine groups: Japan wine, imported wine, and DWF with a 91.1% classification score and 87.9% prediction score. In addition, an LDA model for discrimination of wine from four domestic geographic origins (Yamanashi, Nagano, Hokkaido, and Yamagata Prefectures) using 18 elements gave a classification score of 93.1% and a prediction score of 76.4%. In summary, we have shown that an LDA model based on mineral concentrations is useful for distinguishing Japan wine from other wine groups, and can contribute to classification of the four main domestic wine-producing regions of Japan.

[Comparison between transmission of modern western medicine in China and Japan].

In the middle period of the 16th century, western medicine had been introduced successively into China and Japan by the medium of Catholic missionaries. The transmission mode of western medicine in the two countries differed dramatically from each other due to the political, economic and social cultural differences of that time. In China, the transmission of western medicine focused on the theory first and transferred to the practical use later; while in Japan, it began with clinical treatment, then rose from the technology to the theory. As a result, the cognition to the western medical knowledge and medical system as well as the transplanting and localization in China and Japan were significantly different. The local western medical groups emerged earlier in Japan than in China, and the attitude toward western medicine was also more positive and a national health system was quickly established. The corresponding situation in China obviously lagged behind the one in Japan, and China learned from the successful experiences of Japan for a time.

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.

Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12th, 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate statistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in multivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the occurrence of post-traumatic stress disorder was the result of the interaction of multiple factors. PMID:25206499

History of T-cain: a local anesthetic developed and manufactured in Japan.

Tobe, Masaru; Saito, Shigeru

In many anesthesia textbooks written in English, lidocaine, tetracaine, bupivacaine, ropivacaine, and chloroprocaine are listed as useful local anesthetics for spinal anesthesia. In contrast, T-cain is not included in these lists, even though it has been reported to be suitable for spinal anesthesia in Japan. T-cain was developed as a local anesthetic in the early 1940s by Teikoku Kagaku Sangyo Inc. in Itami, Japan, by replacing a methyl group on tetracaine (Pantocaine(®)) with an ethyl group. T-cain was clinically approved for topical use in Japan in November 1949, and a mixture of dibucaine and T-cain (Neo-Percamin S(®)) was approved for spinal use in May 1950. Simply because of a lack of foreign marketing strategy, T-cain has never attracted global attention as a local anesthetic. However, in Japan, T-cain has been used topically or intrathecally (as Neo-Percamin S(®)) for more than 60 years. Other than the side effects generally known for all local anesthetics, serious side effects have not been reported for T-cain. In fact, several articles have reported that T-cain decreases the neurotoxicity of dibucaine. In this historical review, the characteristics of T-cain and its rise to become a major spinal anesthetic in Japan are discussed.

Back-arc basin opening and closure along the southern margin of the Sea of Japan

Following the tsunami disaster produced by 2001 Off-Tohoku earthquake (M9) along the Pacific coast of Japan, the Japanese government started an intense evaluation of tsunami hazards. This evaluation spanned along the full Japanese coast, including the Sea of Japan coast on the western side of the Japan arc. In the Sea of Japan, tsunamis are produced by crustal faults. As the longer interval of faulting activity, the historical records of tsunamis in the Sea of Japan are not enough for the evaluation of tsunami height. Thus, the evaluation is carried out based on structural analyses of the margin of the Sea of Japan. To get better understanding of the present-day structural geometry and develop a source-fault model in this region, intense seismic reflection profiling has been carried out since 2013. We introduce the results of the seismic reflection profiles and discuss the structural evolution of the southern margin of the Sea of Japan. 2D seismic reflection profiles were acquired using 1950 cu. in. air-gun and 2100 m streamer cable. The seismic profiles provide the image image up to 3 seconds TWT. The southern margin of the Sea of Japan was produced by back-arc opening and post-rift deformation, and the structural evolution of this area is divided into several stages: rifting (25 - 14 Ma), post-rift compression (14 - 5 Ma), weak thrusting (5 - 1 Ma), and strike-slip deformation (1 Ma to present). During the rifting stage that is associated with the fan-shaped opening of the Sea of Japan, grabens and half-grabens were formed trending parallel to the extension of SW-Japan arc. These grabens were filled by syn-rift sediments, and the maximum thickness of basin fill is observed along the southern margin of the rifted crust. The opening of the Sea of Japan ceased as a result of the collision of Izu-Bonin-Mariana arc system at the Izu collision zone on the central part of Honshu, Japan. Soon after the this event, the young Shikoku basin within the Philippine Sea plate

We evaluated the effectiveness of high-frequency transcutaneous electrical nerve stimulation (TENS) as a pain relief resource for primiparous puerpere who had experienced natural childbirth with an episiotomy. A controlled, randomized clinical study was conducted in a Brazilian maternity ward. Forty puerpere were randomly divided into two groups: TENS high frequency and a no treatment control group. Post-episiotomy pain was assessed in the resting and sitting positions and during ambulation. An 11-point numeric rating scale was performed in three separate evaluations (at the beginning of the study, after 60 min and after 120 min). The McGill pain questionnaire was employed at the beginning and 60 min later. TENS with 100 Hz frequency and 75 µs pulse for 60 min was employed without causing any pain. Four electrodes ware placed in parallel near the episiotomy site, in the area of the pudendal and genitofemoral nerves. An 11-point numeric rating scale and McGill pain questionnaire showed a significant statistical difference in pain reduction in the TENS group, while the control group showed no alteration in the level of discomfort. Hence, high-frequency TENS treatment significantly reduced pain intensity immediately after its use and 60 min later. TENS is a safe and viable non-pharmacological analgesic resource to be employed for pain relief post-episiotomy. The routine use of TENS post-episiotomy is recommended. © 2012 The Authors.

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.

Post-Fukushima Energy and Nuclear Policy Evolution

NASA Astrophysics Data System (ADS)

Masuda, Tatsuo

2014-07-01

The Fukushima nuclear disaster should be marked as a point of departure towards energy policy evolution needed in the 21st century. Japan had cast off the skin after the oil shocks of the 1970s, where energy efficiency and saving played a critical role. Japan might have looked very different without these innovative policies. The post-Fukushima Japan faces multiple challenges, each of which constitutes a daunting task for policymakers such as surging LNG import costs and nuclear restarting. However, overcoming these problems one by one is not enough. Intensifying climate impact alerts us to the arrival of a historical inflection point requiring a radical shift in energy model worldwide, where Japan will be best suited to take the lead in view of its energy history and technology. The on-going effort after Fukushima to renew her energy and nuclear policy is suggestive of her potential to develop an innovative energy model by casting off the skin again. Asia will become the "problem centre" of the world if it may fail to address global environmental problems deriving from the heavy use of energy (about 46% of world's energy used by Asia alone in 2035). If successful, on the contrary, Asia will become the "solution centre" benefiting the global community. Asia is too big to fail as the whole world will be badly affected. The new energy model of Japan will serve as "public goods" for Asian countries in developing their new energy model towards sustainable future.

Contribution of different functional groups to the diet of major predatory fishes at a seagrass meadow in northeastern Japan

We examined the variation in habitat use and diet of three dominant fish species ( Myoxocephalus brandti, Pholidapus dybowskii, and Pholis crassispina) in a seagrass meadow in the Akkeshi-ko estuary in northeastern Japan, where broad and dense Zostera marina beds exist, using a semi-quantitative census of the fishes and analyses of their stomach contents. Differences among the three fish species in the temporal variation in abundance of each age class (mainly 1- and 2-year age classes) indicated that the temporal pattern of utilization of the seagrass meadow were different among them. In the semi-quantitative dietary analysis, two prey categories, i.e., taxonomic group (order and suborder) and functional group, were used to explain the variation in prey composition with size-dependent changes. The six prey functional groups were classified based on the ecological traits of the prey, i.e., trophic level, size, and life type (habitat and behavior). Ontogenetic shifts in prey of the three fish species could be fully explained by a combination of the two prey categories, and not by the use of only one category (taxonomic or functional group). The pattern of ontogenetic shifts in prey differed among the fish species and size (age) classes. These results indicate that segregation of habitat (seagrass meadow) and prey group (taxonomic and functional group) is performed among the three species, which may contribute to their coexistence in this estuary.

2015-10-28

We revisited the lessons of the 2011 Great East Japan Earthquake Tsunami disaster specifically on the response and impact, and discussed the paradigm shift of Japan's tsunami disaster management policies and the perspectives for reconstruction. Revisiting the modern histories of Tohoku tsunami disasters and pre-2011 tsunami countermeasures, we clarified how Japan's coastal communities have prepared for tsunamis. The discussion mainly focuses on structural measures such as seawalls and breakwaters and non-structural measures of hazard map and evacuation. The responses to the 2011 event are discussed specifically on the tsunami warning system and efforts to identify the tsunami impacts. The nation-wide post-tsunami survey results shed light on the mechanisms of structural destruction, tsunami loads and structural vulnerability to inform structural rehabilitation measures and land-use planning. Remarkable paradigm shifts in designing coastal protection and disaster mitigation measures were introduced, leading with a new concept of potential tsunami levels: Prevention (Level 1) and Mitigation (Level 2) levels according to the level of 'protection'. The seawall is designed with reference to Level 1 tsunami scenario, while comprehensive disaster management measures should refer to Level 2 tsunami for protection of human lives and reducing potential losses and damage. Throughout the case study in Sendai city, the proposed reconstruction plan was evaluated from the tsunami engineering point of view to discuss how the post 2011 paradigm was implemented in coastal communities for future disaster mitigation. The analysis revealed that Sendai city's multiple protection measures for Level 2 tsunami will contribute to a substantial reduction of the tsunami inundation zone and potential losses, combined with an effective tsunami evacuation plan. © 2015 The Author(s).

Global medical devices have become more popular, but investment money for medical device development is not easily available in the market. Worldwide health-care budget constraints mean that efficient medical device development has become essential. To achieve efficient development, globalization is a key to success. Spending large amounts of money in different regions for medical device development is no longer feasible. In order to streamline processes of global medical device development, an academic, governmental, and industrial consortium, called the Harmonization by Doing program, has been set up. The program has been operating between Japan and the USA since 2003. The program has 4 working groups: (1) Global Cardiovascular Device Trials; (2) Study on Post-Market Registry; (3) Clinical Trials; and (4) Infrastructure and Methodology Regulatory Convergence and Communication. Each working group has as its goals the achievement of speedy and efficient medical device development in Japan and the USA. The program has held multiple international meetings to deal with obstacles against efficient medical device development. This kind of program is very important to deliver novel medical devices. Involvement of physicians in this type of activity is also very helpful to achieve these goals.

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.

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.

Legalized abortion in Japan.

PubMed

Hart, T M

1967-10-01

The enactment of the Eugenic Protection Act in Japan was followed by many changes. The population explosion was stemmed, the birth rate was halved, and while the marriage rate remained steady the divorce rate declined. The annual total of abortions increased until 1955 and then slowly declined. The highest incidence of abortions in families is in the 30 to 34 age group when there are four children in the family. As elsewhere abortion in advanced stages of pregnancy is associated with high morbidity and mortality. There is little consensus as to the number of criminal abortions. Reasons for criminal abortions can be found in the legal restrictions concerning abortion: Licensing of the abortionist, certification of hospitals, taxation of operations and the requirement that abortion be reported. Other factors are price competition and the patient's desire for secrecy. Contraception is relatively ineffective as a birth control method in Japan. Oral contraceptives are not yet government approved. In 1958 alone 1.1 per cent of married women were sterilized and the incidence of sterilization was increasing.

In Japan, when pharmaceutical companies launch a new drug, they are obligated to conduct a post-marketing survey to evaluate the safety and efficacy of the drug in accordance with Good Post-Marketing Surveillance Practice under Article 14.4 (re-examination) of the Pharmaceutical Affairs Law at contracted medical institutions. We report the results of a drug use survey, which we conducted as a post-marketing survey. This prospective post-marketing drug use survey was conducted to assess the safety and efficacy of the β-adrenergic receptor antagonist (β-blocker) Artist® Tablets (carvedilol) in patients with hypertension in Japan. Patients were carvedilol-naive and had essential hypertension or renal parenchymal hypertension. This was a prospective survey conducted over 3 years from October 1993 to September 1996. The standard observation period for the patients was defined as 12 weeks of treatment with carvedilol. We collected data on 4961 patients at 561 medical institutions who had not been previously treated with carvedilol; 4574 patients were included in the safety analysis and 4422 in the efficacy analysis. The incidence of adverse drug reactions (the proportion of patients with adverse drug reactions) was 4.31% (197 of 4574 patients), which is less than that shown in the pre-approval clinical trial of carvedilol (6.85% [68 of 993]). The most common adverse drug reactions were bradycardia, dizziness, hypotension, headache, and feeling light-headed. After 12 weeks' treatment with carvedilol, systolic/diastolic blood pressure (SBP/DBP) was reduced from 168.2 ± 18.6/95.7 ± 11.3 mmHg at baseline to 144.3 ± 17.3/83.4 ± 10.8 mmHg. Patients were classified according to which antihypertensive drug they had been using when carvedilol treatment was initiated. Coadministered agents were calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors (ACEIs), diuretics, and α-adrenergic receptor antagonists (α-blockers). At 12 weeks

Deaths from heat-stroke in Japan: 1968-1994

Nakai, S.; Itoh, T.; Morimoto, T.

Global warming is increasingly recognized as a threat to the survival of human beings, because it could cause a serious increase in the occurrence of diseases due to environmental heat during intermittent hot weather. To assess the direct impact of extremely hot weather on human health, we investigated heat-related deaths in Japan from 1968 through 1994, analyzing the data to determine the distribution of the deaths by age and their correlation to the incidence of hot days in summer. Vital Statistics of Japan, published by the Ministry of Health and Welfare of Japan, was the source of the heat-related mortality data employed in this study. Meteorological data were obtained from the District Meteorological Observatories in Tokyo and Osaka, the two largest cities in Japan. Heat-related deaths were most prone to occur on days with a peak daily temperature above 38°C, and the incidence of these deaths showed an exponential dependence on the number of hot days. Thus, even a small rise in atmospheric temperature may lead to a considerable increase in heat-related mortality, indicating the importance of combating global warming. Furthermore, half (50.1%) of the above-noted deaths occurred in children (4 years and under) and the elderly (70 years and over) irrespective of gender, indicating the vulnerability of these specific age groups to heat. Since a warmer climate is predicted in the future, the incidence of heat waves will increase, and more comprehensive measures, both medical and social, should be adopted for children of 4 years and younger the elderly to prevent heat-related deaths in these age groups.

Measures against transmission of pandemic H1N1 influenza in Japan in 2009: simulation model.

The first outbreak of pandemic H1N1 influenza in Japan was contained in the Kansai region in May 2009 by social distancing measures. Modelling methods are needed to estimate the validity of these measures before their implementation on a large scale. We estimated the transmission coefficient from outbreaks of pandemic H1N1 influenza among school children in Japan in summer 2009; using this transmission coefficient, we simulated the spread of pandemic H1N1 influenza in a virtual community called the virtual Chuo Line which models an area to the west of metropolitan Tokyo. Measures evaluated in our simulation included: isolation at home, school closure, post-exposure prophylaxis and mass vaccinations of school children. We showed that post-exposure prophylaxis combined with isolation at home and school closure significantly decreases the total number of cases in the community and can mitigate the spread of pandemic H1N1 influenza, even when there is a delay in the availability of vaccine.

Abstract Objective To assess the burden posed by foodborne diseases in Japan using methods developed by the World Health Organization’s Foodborne Disease Burden Epidemiology Reference Group (FERG). Methods Expert consultation and statistics on food poisoning during 2011 were used to identify three common causes of foodborne disease in Japan: Campylobacter and Salmonella species and enterohaemorrhagic Escherichia coli (EHEC). We conducted systematic reviews of English and Japanese literature on the complications caused by these pathogens, by searching Embase, the Japan medical society abstract database and Medline. We estimated the annual incidence of acute gastroenteritis from reported surveillance data, based on estimated probabilities that an affected person would visit a physician and have gastroenteritis confirmed. We then calculated disability-adjusted life-years (DALYs) lost in 2011, using the incidence estimates along with disability weights derived from published studies. Findings In 2011, foodborne disease caused by Campylobacter species, Salmonella species and EHEC led to an estimated loss of 6099, 3145 and 463 DALYs in Japan, respectively. These estimated burdens are based on the pyramid reconstruction method; are largely due to morbidity rather than mortality; and are much higher than those indicated by routine surveillance data. Conclusion Routine surveillance data may indicate foodborne disease burdens that are much lower than the true values. Most of the burden posed by foodborne disease in Japan comes from secondary complications. The tools developed by FERG appear useful in estimating disease burdens and setting priorities in the field of food safety. PMID:26478611

Open literature review of threats including sabotage and theft of fissile material transport in Japan.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cochran, John Russell; Furaus, James Phillip; Marincel, Michelle K.

This report is a review of open literature concerning threats including sabotage and theft related to fissile material transport in Japan. It is intended to aid Japanese officials in the development of a design basis threat. This threat includes the external threats of the terrorist, criminal, and extremist, and the insider threats of the disgruntled employee, the employee forced into cooperation via coercion, the psychotic employee, and the criminal employee. Examination of the external terrorist threat considers Japanese demographics, known terrorist groups in Japan, and the international relations of Japan. Demographically, Japan has a relatively homogenous population, both ethnically andmore » religiously. Japan is a relatively peaceful nation, but its history illustrates that it is not immune to terrorism. It has a history of domestic terrorism and the open literature points to the Red Army, Aum Shinrikyo, Chukaku-Ha, and Seikijuku. Japan supports the United States in its war on terrorism and in Iraq, which may make Japan a target for both international and domestic terrorists. Crime appears to remain low in Japan; however sources note that the foreign crime rate is increasing as the number of foreign nationals in the country increases. Antinuclear groups' recent foci have been nuclear reprocessing technology, transportation of MOX fuel, and possible related nuclear proliferation issues. The insider threat is first defined by the threat of the disgruntled employee. This threat can be determined by studying the history of Japan's employment system, where Keiretsu have provided company stability and lifetime employment. Recent economic difficulties and an increase of corporate crime, due to sole reliability on the honor code, have begun to erode employee loyalty.« less

Although statin therapy is beneficial for the prevention of initial stroke, the benefit for recurrent stroke and its subtypes remains to be determined in Asian, in whom stroke profiles are different from Caucasian. This study examined whether treatment with low-dose pravastatin prevents stroke recurrence in ischemic stroke patients. This is a multicenter, randomized, open-label, blinded-endpoint, parallel-group study of patients who experienced non-cardioembolic ischemic stroke. All patients had a total cholesterol level between 4.65 and 6.21 mmol/L at enrollment, without the use of statins. The pravastatin group patients received 10 mg of pravastatin/day; the control group patients received no statins. The primary endpoint was the occurrence of stroke and transient ischemic attack (TIA), with the onset of each stroke subtype set to be one of the secondary endpoints. Although 3000 patients were targeted, 1578 patients (491 female, age 66.2 years) were recruited and randomly assigned to pravastatin group or control group. During the follow-up of 4.9 ± 1.4 years, although total stroke and TIA similarly occurred in both groups (2.56 vs. 2.65%/year), onset of atherothrombotic infarction was less frequent in pravastatin group (0.21 vs. 0.64%/year, p = 0.0047, adjusted hazard ratio 0.33 [95%CI 0.15 to 0.74]). No significant intergroup difference was found for the onset of other stroke subtypes, and for the occurrence of adverse events. Although whether low-dose pravastatin prevents recurrence of total stroke or TIA still needs to be examined in Asian, this study has generated a hypothesis that it may reduce occurrence of stroke due to larger artery atherosclerosis. This study was initially supported by a grant from the Ministry of Health, Labour and Welfare, Japan. After the governmental support expired, it was conducted in collaboration between Hiroshima University and the Foundation for Biomedical Research and Innovation.

"Japan's population is aging faster than that of any other country in the world. The unprecedented increase in retirees relative to the size of Japan's work force will force radical change if the nation is to avoid a fiscal crisis, or worse. These seemingly innocent demographic changes will force Japan to shrink its famously high savings rate, reverse its proud trade surplus, send more industry overseas, liberalize its tightly controlled markets, and take on a more active, high-profile foreign policy. Ultimately, these changes will shift the balance of power in East Asia." excerpt

The Great East Japan earthquake and tsunami caused immense damage over a wide area of eastern Japan. Hence, many survivors are at high risk for posttraumatic stress disorder (PTSD). This randomized, observer-blinded, controlled trial examined the efficacy and safety of the traditional Japanese herbal formula saikokeishikankyoto (SKK) in the treatment of PTSD among survivors of this disaster. Forty-three participants with an Impact of Event Scale-Revised (IES-R) score ≥ 25 were randomized into SKK (n = 21) and control (n = 22) groups. The primary endpoint was the change in IES-R scores from baseline till after 2 weeks of treatment. Intergroup statistical comparisons were performed. The magnitude of changes in total IES-R scores differed significantly between the two groups (P < 0.001). Post hoc analysis showed that the total IES-R score improved significantly in the SKK group from 49.6 ± 11.9 to 25.5 ± 17.0 (P < 0.001). Subscale scores improved significantly in the SKK group (avoidance, P = 0.003; hyperarousal, P < 0.001; intrusion, P < 0.001). Two-week treatment with SKK significantly improved IES-R scores among PTSD patients. This traditional medicine may be a valid choice for the treatment of psychological and physical symptoms in PTSD patients. PMID:24790634

THE FIRST EUROPEANS to discover Japan were Portuguese traders who arrived in 1542. Fifteen years later, the Portuguese Jesuit priest and surgeon Luis De Almeida (1525-1583) founded the first Western hospital in Japan, for the care of lepers, syphilitics, and orphans. Because the hospital had a negative influence on the spread of Christianity, the Jesuits closed it in 1586. During the Tokugawa Shogunate (1600-1868), when Japan was secluded from the rest of the world, the only foreign physicians allowed to enter Japan were those employed by the Dutch factory at Dejima in Nagasaki. Only four of those physicians left behind seeds for the foundation of Western medicine in Japan, namely Caspar Schambergen, who founded a Japanese school of surgery in 1650; Engelbert Kämpfer, who visited Japan in 1691 to 1692; Carl Peter Thunberg, who botanically explored Japan in 1775 to 1776; and Philipp Franz Balthasar von Siebold, who practiced medicine in Nagasaki in 1823 to 1829 and 1859 to 1861. On the whole, Western medicine and surgery never established a real foothold in Japan until the fall of the shogunate and the restoration of the emperor in 1868.

Changes in metabolic profiles after the Great East Japan Earthquake: a retrospective observational study

PubMed Central

2013-01-01

Background A magnitude 9.0 earthquake struck off eastern Japan in March 2011. Many survivors have been living in temporary houses provided by the local government since they lost their houses as a result of the great tsunami (tsunami group) or the expected high-dose radiation resulting from the nuclear accident at the Fukushima Daiichi Nuclear Power Plant (radiation group). The tsunami was more than 9 m high in Soma, Fukushima, which is located 30 km north of the Fukushima Daiichi Nuclear Power Plant and adjacent to the mandatory evacuation area. A health screening program was held for the evacuees in Soma in September 2011. The aim of this study was to compare the metabolic profiles of the evacuees before and after the disaster. We hypothesized that the evacuees would experience deteriorated metabolic status based on previous reports of natural disasters. Methods Data on 200 subjects who attended a health screening program in September or October of 2010 (pre-quake) and 2011 (post-quake) were retrospectively reviewed and included in this study. Pre-quake and post-quake results of physical examinations and laboratory tests were compared in the tsunami and radiation groups. A multivariate regression model was used to determine pre-quake predictive factors for elevation of hemoglobin A1c (HbA1c) in the tsunami group. Results Significantly higher values of body weight, body mass index, waist circumference, and HbA1c and lower high-density lipoprotein cholesterol levels were found at the post-quake screening when compared with the pre-quake levels (p = 0.004, p = 0.03, p = 0.008, p < 0.001, and p = 0.03, respectively). A significantly higher proportion of subjects in the tsunami group with high HbA1c, defined as ≥5.7%, was observed after the quake (34.3%) than before the quake (14.8%) (p < 0.001). Regional factors, periodic clinic visits, and waist circumference before the quake were identified as predictive factors on multivariate analysis for the deterioration

Group A rotaviruses (RVAs) are a major cause of acute dehydrating diarrhea in infants and young animals worldwide. RVAs have also been detected in several wild and zoo animals, indicating wide susceptibility of wild animals. However, the role of wild animals in the infection cycle of RVAs is unclear. Wild boars are indigenous in many countries in the world. Japanese wild boars (Sus scrofa leucomystax) have been migrating close to human habitats in Japan, indicating the possibility of natural transmission between domestic animals or humans and wild boars. We investigated infection of RVAs in wild boars in Japan to identify types of RVAs infecting wild animals. We obtained stool samples from 90 wild boars and detected a VP4 gene of RVAs by RT-semi-nested PCR. RVAs were detected in samples from four of the 90 wild boars. Nucleotide analyses of VP7 and VP4 genes revealed that the four strains belong to G9P[23], G4P[23], G9P[13] and G4P[6], suggesting a relation to porcine and human RVAs. We therefore characterized RVAs circulating among domestic pigs living in the same area as the wild boars. We collected stool samples from 82 domestic pigs. RVAs were detected in samples from 49 of the 82 domestic pigs. Phylogenetic and similarity analyses provided evidence for natural transmission between domestic pigs and wild boars. The results also suggested that natural reassortment events occurred before or after transmission between domestic pigs and wild boars. Our findings indicate the possibility that RVAs circulate among wild animals, humans and domestic animals in nature. Copyright © 2013 Elsevier B.V. All rights reserved.

Japan's anti-nuclear weapons policy misses its target, even in the war on terrorism.

PubMed

DiFilippo, Anthony

2003-01-01

While actively working to promote the abolition of all nuclear weapons from the world since the end of the cold war, Japan's disarmament policies are not without problems. Promoting the elimination of nuclear weapons as Japan remains under the US nuclear umbrella creates a major credibility problem for Tokyo, since this decision maintains a Japanese deterrence policy at the same time that officials push for disarmament. Tokyo also advocates a gradual approach to the abolition of nuclear weapons, a decision that has had no effect on those countries that have been conducting sub-critical nuclear testing, nor stopped India and Pakistan from carrying out nuclear tests. Consistent with Article 9 of the Constitution, the Japanese war-renouncing constitutional clause, Tokyo toughened Japan's sizeable Official Development Assistance (ODA) programme in the early 1990s. Because of the anti-military guidelines included in Japan's ODA programme, Tokyo stopped new grant and loan aid to India and Pakistan in 1998 after these countries conducted nuclear tests. However, because of the criticism Japan faced from its failure to participate in the 1991 Gulf War, Tokyo has been seeking a new Japanese role in international security during the post-cold war period. Deepening its commitment to the security alliance with the US, Tokyo has become increasingly influenced by Washington's global polices, including the American war on terrorism. After Washington decided that Pakistan would be a key player in the US war on terrorism, Tokyo restored grant and loan aid to both Islamabad and New Delhi, despite the unequivocal restrictions of Japan's ODA programme.

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.

This study aimed to collect information on experiences in the Great East Japan Earthquake (hereafter, 3.11), current preparedness, and barriers to building up stockpiles in nursery schools in affected areas. Based on the needs heard from the staff, we decided what contents should be included in our manual developed with the Japan Dietetic Association. A group interview was held in September 2012. We interviewed a principal, nurses, and registered dietitians working for a public and a private nursery school in Town A. We also invited an administrative dietitian who was an employee of Town A. One of the barriers to building up stockpiles was that they did not have any idea of what and how many items they should store. To deal with this situation, we developed a formula that could be used to calculate the quantity of stockpiles for their facilities in a newly developed feeding manual. In terms of current preparedness, the registered dietitians were not prepared for alternative menus in emergencies or how to manage garbage when the garbage collection was disrupted by disasters. The manual recommends to obtain the services of at least two food service personnel and spare space for storing filled garbage bags until garbage collection resumes. Some improvements in stocks were found in both of the public and private nursery schools. To improve the situation further, more financial support and detailed guidelines should be provided by the local government and authoritative organizations. Our manual should be a great asset for all nursery schools to improve their stockpiles.

Three Japanese sunspot drawings associated with Iwahashi Zenbei (1756 - 1811) are shown here from contemporary manuscripts and woodprint documents with the relevant texts. We reveal the observational date of one of the drawings to be 26 August 1793, and the overall observations lasted for over a year. Moreover, we identify the observational site for the dated drawing as Fushimi in Japan. We then compare Zenbei's observations with the group sunspot number and the raw group count from the Sunspot Index and Long-term Solar Observations (SILSO) to reveal the context of the data, and we conclude that these drawings fill gaps in our understanding that are due to the fragmental sunspot observations around 1793. These drawings are important as a clue to evaluate astronomical knowledge of contemporary Japan in the late eighteenth century and are valuable as a non-European observation, considering that most sunspot observations up to the middle of the nineteenth century are from Europe.

Our objective was to explore the efficacy and safety of edaravone in amyotrophic lateral sclerosis (ALS) patients with a Japan ALS severity classification of Grade 3. In a 24-week, double-blind, randomized study, 25 patients who met all of the following criteria were enrolled: Japan ALS severity classification Grade 3; definite, probable, or probable-laboratory supported ALS (El Escorial/revised Airlie House); forced vital capacity (%FVC) ≥60%; duration of disease ≤3 years at consent; and change in the revised ALS functional rating scale (ALSFRS-R) score of -1 to -4 points during the 12-week pre-observation period. Patients received edaravone (n = 13) or placebo (n = 12) for six cycles. The efficacy outcome was change in the ALSFRS-R score. The least-squares mean change in the ALSFRS-R score ± standard error during the 24-week treatment was -6.52 ± 1.78 in the edaravone group and -6.00 ± 1.83 in the placebo group; the difference of -0.52 ± 2.46 was not statistically significant (p = 0.835). Incidence of adverse events was 92.3% (12/13) in the edaravone group and 100.0% (12/12) in the placebo group. There was no intergroup difference in the changes in the ALSFRS-R score. The incidences of adverse events were similar in the two groups.

The development of drugs and medical devices is necessary for medical progress; however, safety measures need to be put in place to protect the health of the population. In order to ensure the safety of drugs and medical devices, it is important to determine measures for appropriate management of risks at any time during the development phase, the regulatory review and the post-marketing phase. Adverse events detected in clinical trials are limited due to the restricted numbers of patients enrolled in the trials. Therefore, it is almost impossible to predict rare serious adverse events during the post-marketing phase. The revised Pharmaceutical Affairs Act was established in Japan in November 20, 2013. The new act focuses on increased safety of drugs and medical devices. The Pharmaceuticals and Medical Devices Agency (PMDA) is the regulatory authority in Japan that promotes safety measures from the development phase through to the post-marketing phase. In the post-marketing phase, the PMDA collects information from the medical product companies and healthcare professionals, as well as instructing and advising them with regard to post-marketing safety measures for each drug and medical device. Since Japan has a national health insurance system, a new drug or a medical device is available throughout the country when the drug price or medical fee is listed in the National Health Insurance price list. Healthcare professionals in medical institutions must learn about the drugs and medical devices they handle, and should make an effort to maintain patient safety. The PMDA medi-navi is a very useful electronic mail delivery service that provides critical information for protecting patients from health hazards caused by adverse events. The 'risk management plan' is also important as it contains important information about safety profile and post-marketing measures of a new drug.

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.

Increased shipping in British Columbia (BC) waters poses risks for marine birds from marine oil spills. Ancient Murrelets (Synthliboramphus antiquus), small marine diving birds of which half of the world's population breeds in BC, are especially susceptible to oiling immediately after departing from their breeding colonies, as their offspring are flightless, constraining their parents to remain with them. In 2014 we deployed geolocator loggers on Ancient Murrelets at four breeding colonies, two on the east and two on the west coast of Haida Gwaii to investigate patterns of post-breeding dispersal and subsequent migratory movements. Birds from east coast colonies moved south and east after leaving their colonies, remaining in Queen Charlotte Sound and adjacent waters for 4-6 weeks, whereas those from west coast colonies moved steadily north and west, so that they left BC waters earlier than those from east coast colonies. These movements were consistent with being driven by surface currents. In June, all birds moved rapidly to the eastern Aleutians, SE Bering Sea, and waters off Kamchatka, where they probably moulted. In August, most moved north, some passing through Bering Straits into the Chukchi Sea. In October-November some birds returned to waters off western N America (33%) and the remainder carried on westwards to waters off Japan, Korea and NE China. For the former group the movement to the Bering Sea in June constituted a moult migration and, as such, is the first described for an auk. Those birds wintering in Asia began moving east in February and arrived off BC in March, when observations at colonies show that burrow visits begin in Haida Gwaii. Our data suggest that, immediately after colony departure, birds from the east coast colonies (about half the population of Haida Gwaii) are at higher risk from potential oil spills in northern British Columbia waters than those breeding on the west coast.

INTRODUCTION Japan is a developed country with high use of Internet and online platforms for health information. 'Yahoo! Answer Japan' is the most commonly used question-and-answer service in Japan. AIM To explore the information users seek regarding breast cancer from the 'Yahoo! Answer Japan' web portal. METHODS The 'Yahoo! Answer Japan' portal was searched for the key word 'breast cancer' and all questions searched for the period of 1 January to 31 December 2014 were obtained. The selected questions related to human breast cancer and were not advertisements or promotional material. The questions were categorized using a coding schema. High and low access of the questions were defined by the number of view-counts. RESULTS Among the 2392 selected questions, six major categories were identified; (1) suspected breast cancer, (2) breast cancer screening, (3) treatment of breast cancer, (4) life with breast cancer, (5) prevention of breast cancer and (6) others. The highest number of questions were treatment related (28.8%) followed by suspected breast cancer-related questions (23.4%) and screening-related questions (20%). Statistical analysis revealed that the treatment-related questions were more likely to be highly accessed. CONCLUSION Content analysis of Internet question-answer communities is important, as questions posted on these sites would serve as a rich source of direct reflection regarding the health-related information needs of the general population.

Pacific bluefin tuna transport Fukushima-derived radionuclides from Japan to California

Madigan, Daniel J.; Baumann, Zofia; Fisher, Nicholas S.

2012-01-01

The Fukushima Dai-ichi release of radionuclides into ocean waters caused significant local and global concern regarding the spread of radioactive material. We report unequivocal evidence that Pacific bluefin tuna, Thunnus orientalis, transported Fukushima-derived radionuclides across the entire North Pacific Ocean. We measured γ-emitting radionuclides in California-caught tunas and found 134Cs (4.0 ± 1.4 Bq kg−1) and elevated 137Cs (6.3 ± 1.5 Bq kg−1) in 15 Pacific bluefin tuna sampled in August 2011. We found no 134Cs and background concentrations (∼1 Bq kg−1) of 137Cs in pre-Fukushima bluefin and post-Fukushima yellowfin tunas, ruling out elevated radiocesium uptake before 2011 or in California waters post-Fukushima. These findings indicate that Pacific bluefin tuna can rapidly transport radionuclides from a point source in Japan to distant ecoregions and demonstrate the importance of migratory animals as transport vectors of radionuclides. Other large, highly migratory marine animals make extensive use of waters around Japan, and these animals may also be transport vectors of Fukushima-derived radionuclides to distant regions of the North and South Pacific Oceans. These results reveal tools to trace migration origin (using the presence of 134Cs) and potentially migration timing (using 134Cs:137Cs ratios) in highly migratory marine species in the Pacific Ocean.

This study presents the first investigation of concentrations and congener group patterns of atmospheric short-chain chlorinated paraffins (SCCPs) throughout East Asia. Based on an absorption rate calibration experiment, a spatial survey of SCCPs was performed using passive air samplers in China, Japan, and South Korea during two separate periods in 2008. The atmospheric concentrations of SCCPs in China were clearly greater than those in Japan and South Korea, both of which exceed the levels determined for other regions of the world. C(10) components were the most abundant type of SCCPs in China, whereas C(11) components were dominant in Japan and South Korea. With respect to the total chlorine content, Cl(6) and Cl(5) were the predominant compounds in China and Japan; however, Cl(6) and Cl(7) were predominant in South Korea. A similar pattern was also found for remote sites within China, Japan, and South Korea, respectively. Together with the back-trajectories calculated for the remote sites, the results indicate that the SCCPs in the air of East Asia were mainly influenced by local sources due to their relatively low long-range atmospheric transport potential compared to other POPs.

To determine the effect of a decision support technology on teamwork and associated non-technical (NTS) and technical skills when teams manage post-partum haemorrhage (PPH) in the simulated environment. Multidisciplinary (MDT) maternity teams were taught how to manage post partum haemorrhage. They were randomised to the intervention: using a decision support mobile digital platform or a control group. Each team managed a post-partum simulation, which was recorded and reviewed by assessors. Primary outcome measures to assess teams NTS were the validated Global Assessment of Obstetric Team Performance (GAOTP) and Clinical Teamwork Scale (CTS). Secondary outcome measures were the 'friends and family test', technical skills, and the System Usability Scale (SUS). Sample size estimation was calculated by using 80% power 5% significance two tailed test (p1=85% p2=40%) n=34. 38 teams from August 2014-February 2016, were recruited, technical issues with failure of recording equipment meant 4 teams were excluded from teamwork analysis (1 intervention 3 control). Teamwork improved across all domains with the intervention (using a decision support mobile digital platform) p <0.01. CTS improved between 6.7-16.8% (average 14.2%) and GAOTP between 8.6-17.1% (average 13.5%) for all domains. Using the control group as baseline, the intervention improved teamwork by 25% using CTS and 22% using GAOTP. Fewer technical skills were missed with the intervention (p<0.01). There was no statistical difference in the time technical skills were achieved. Assessors were more likely to recommend intervention teams 87.5% (77/88) than control teams 63.6% (56/88) p<0.01 to their friends or family. The SUS was 'Good' (69) becoming excellently 'Usable' (81.6) over the study period. We report a decision support system, which improved NTS when managing PPH. Lack of teamwork is often cited as the cause of failures in care and we report a usable technology that assists with and improves teamwork during

Recombinant DNA technology was developed in the United States in the early 1970s. Leading scientists held an international Asilomar Conference in 1975 to examine the self regulation of recombinant DNA technology, followed by the U.S. National Institutes of Health drafting the Recombinant DNA Research Guidelines in 1976. The result of this conference significantly affected many nations, including Japan. However, there have been few historical studies on the self-regulation of recombinant technologies conducted by scientists and government officials in Japan. The purpose of this paper is to analyze how the Science Council of Japan, the Ministry of Education, Science adn Culture, and the Science and Technology Agency developed self-regulation policies for recombinant DNA technology in Japan in the 1970s. Groups of molecular biologist and geneticists played a key role in establishing guidelines in cooperation with government officials. Our findings suggest that self-regulation policies on recombinant DNA technology have influenced safety management for the life sciences and establishment of institutions for review in Japan.

Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography (ERCP). Rectal nonsteroidal anti-inflammatory drugs (specifically, 100 mg of diclofenac or indomethacin) have shown promising prophylactic activity in post-ERCP pancreatitis (PEP). However, the 100-mg dose is higher than that ordinarily used in Japan. We performed a prospective randomized controlled study to evaluate the efficacy of low-dose rectal diclofenac for the prevention of PEP. Patients who were scheduled to undergo ERCP were randomized to receive a saline infusion either with 50 mg of rectal diclofenac (diclofenac group) or without (control group) 30 min before ERCP. The dose of diclofenac was reduced to 25 mg in patients weighing <50 kg. The primary outcome measure was the occurrence of PEP. Enrollment was terminated early because the planned interim analysis found a statistically significant intergroup difference in the occurrence of PEP. A total of 104 patients were eligible for this study; 51 patients received rectal diclofenac. Twelve patients (11.5%) developed PEP: 3.9% (2/51) in the diclofenac group and 18.9% (10/53) in the control group (p = 0.017). After ERCP, the incidence of hyperamylasemia was not significantly different between the two groups. Post-ERCP pain was significantly more frequent in the control group than in the diclofenac group (37.7 vs. 7.8%, respectively; p < 0.001). There were no adverse events related to diclofenac. Low-dose rectal diclofenac can prevent PEP.

First the Japan earthquake, then tsunami, now a country with more than 20,000 known dead and missing must cope with the threat of nuclear contamination. Disaster may place survivors at risk for a range of negative outcomes. Disaster-related mental health problems may include acute stress disorder, post-traumatic stress disorder, and depression. The individuals with psychologically wounded by this disaster will leave their imprint for years, even decades, to come. We are now planning to open a new department named Psychiatric services for the survivors of natural disasters. Through the activities of this department, we aim to continue daily psychiatric services and to promote wellness of the survivors. Thus, we are making a system to recruit and dispatch psychiatrists for the psychiatric services at the damaged areas. On the other hand, in modern Japan society, namely aging society with low birth rate, the latent ability of university students is indispensable for the recovery after big disasters. We will take their academic ability into the activities of the new department. We also plan to promote their wellness through this kind of volunteer acidity.

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.

The aim of the present study was to examine the possibility of screening apprehensive pregnant women and mothers at risk for post-partum depression from an analysis of the textual data in the Mother and Child Handbook by using the text-mining method. Uncomplicated pregnant women (n = 58) were divided into two groups according to State-Trait Anxiety Inventory grade (high trait [group I, n = 21] and low trait [group II, n = 37]) or Edinburgh Postnatal Depression Scale score (high score [group III, n = 15] and low score [group IV, n = 43]). An exploratory analysis of the textual data from the Maternal and Child Handbook was conducted using the text-mining method with the Word Miner software program. A comparison of the 'structure elements' was made between the two groups. The number of structure elements extracted by separated words from text data was 20 004 and the number of structure elements with a threshold of 2 or more as an initial value was 1168. Fifteen key words related to maternal anxiety, and six key words related to post-partum depression were extracted. The text-mining method is useful for the exploratory analysis of textual data obtained from pregnant woman, and this screening method has been suggested to be useful for apprehensive pregnant women and mothers at risk for post-partum depression. © 2016 Japan Society of Obstetrics and Gynecology.

Nutritional standards are important guidelines for providing students with nutritionally-balanced school meals. This study compared nutrient-based school lunch standards regulated by South Korea, Japan, and Taiwan. The data were collected from relevant literature and websites of each country during September 2014. The number of classification groups of target students was 8, 5, and 5 for South Korea, Japan, and Taiwan, respectively. Gender was considered across all age groups in South Korea but only for high school students in Taiwan. Gender was not considered in Japan. Along with energy, the number of nutrients included in the standards for South Korea, Japan and Taiwan was 9, 12, and 4, respectively. The standards for all three countries included protein and fat among macronutrients. The standards for South Korea and Japan included vitamin A, B-1, B-2, and C, while the standards for Taiwan did not include any vitamins. Calcium was the only mineral commonly included in the three standards. The proportions of recommended daily intakes as reference values for each nutrient differed among the countries. Japan differentiated the proportions among 33%, 40%, or 50%, reflecting the target students' intake status of the respective nutrients. Taiwan differentiated either two-fifths or one-third of the recommended daily intakes. South Korea applied the proportion of recommended daily intake as one-third for all selected nutrients. This study could be valuable information for countries in developing nutrient-based standards for school lunches and for South Korea, Japan, and Taiwan in the process of reforming nutrient-based standards.

Recent damaging earthquakes in Japan, 2003-2008

During the last six years, from 2003-2008, Japan has been struck by three significant and damaging earthquakes: The most recent M6.6 Niigata Chuetsu Oki earthquake of July 16, 2007 off the coast of Kashiwazaki City, Japan; The M6.6 Niigata Chuetsu earthquake of October 23, 2004, located in Niigata Prefecture in the central Uonuma Hills; and the M8.0 Tokachi Oki Earthquake of September 26, 2003 effecting southeastern Hokkaido Prefecture. These earthquakes stand out among many in a very active period of seismicity in Japan. Within the upper 100 km of the crust during this period, Japan experienced 472 earthquakes of magnitude 6, or greater. Both Niigata events affected the south-central region of Tohoku Japan, and the Tokachi-Oki earthquake affected a broad region of the continental shelf and slope southeast of the Island of Hokkaido. This report is synthesized from the work of scores of Japanese and US researchers who led and participated in post-earthquake reconnaissance of these earthquakes: their noteworthy and valuable contributions are listed in an extended acknowledgements section at the end of the paper. During the Niigata Chuetsu Oki event of 2007, damage to the Kashiwazaki-Kariwa nuclear power plant, structures, infrastructure, and ground were primarily the product of two factors: (1) high intensity motions from this moderate-sized shallow event, and (2) soft, poor performing, or liquefiable soils in the coastal region of southwestern Niigata Prefecture. Structural and geotechnical damage along the slopes of dunes was ubiquitous in the Kashiwazaki-Kariwa region. The 2004 Niigata Chuetsu Earthquake was the most significant to affect Japan since the 1995 Kobe earthquake. Forty people were killed, almost 3,000 were injured, and many hundreds of landslides destroyed entire upland villages. Landslides were of all types; some dammed streams, temporarily creating lakes threatening to overtop their new embankments and cause flash floods and mudslides. The numerous

Objectives The objective of this study was to longitudinally examine the geographic distribution of physicians in Japan with adjustment for healthcare demand according to changes in population age structure. Methods We examined trends in the number of physicians per 100 000 population in Japan's secondary medical areas (SMAs) from 2000 to 2014. Healthcare demand was adjusted using health expenditure per capita. Trends in the Gini coefficient and the number of SMAs with a low physician supply were analysed. A subgroup analysis was also conducted where SMAs were divided into 4 groups according to urban–rural classification and initial physician supply. Results The time-based changes in the Gini coefficient and the number of SMAs with a low physician supply indicated that the equity in physician distribution had worsened throughout the study period. The number of physicians per 100 000 population had seemingly increased in all groups, with increases of 22.9% and 34.5% in urban groups with higher and lower initial physician supply, respectively. However, after adjusting healthcare demand, physician supply decreased by 1.3% in the former group and increased by 3.5% in the latter group. Decreases were also observed in the rural groups, where the number of physicians decreased by 4.4% in the group with a higher initial physician supply and 7.6% in the group with a lower initial physician supply. Conclusions Although the total number of physicians increased in Japan, demand-adjusted physician supply decreased in recent years in all areas except for urban areas with a lower initial physician supply. In addition, the equity of physician distribution had consistently deteriorated since 2000. The results indicate that failing to adjust healthcare demand will produce misleading results, and that there is a need for major reform of Japan's healthcare system to improve physician distribution.

The 23rd World Scout Jamboree was held in Japan from 28 July to 8 August 2015 and was attended by over 33,000 scouts from 162 countries. An outbreak of invasive meningococcal disease capsular group W was investigated among participants, with four confirmed cases identified in Scotland, who were all associated with one particular scout unit, and two confirmed cases in Sweden; molecular testing showed the same strain to be responsible for illness in both countries. The report describes the public health action taken to prevent further cases and the different decisions reached with respect to how wide to extend the offer of chemoprophylaxis in the two countries; in Scotland, chemoprophylaxis was offered to the unit of 40 participants to which the four cases belonged and to other close contacts of cases, while in Sweden chemoprophylaxis was offered to all those returning from the Jamboree. The report also describes the international collaboration and communication required to investigate and manage such multinational outbreaks in a timely manner. PMID:27918267

This study examines the economic effects of Japan's Mikawa Port on Aichi Prefecture before and after a natural disaster interrupts its operations for one year. Using a regional input-output model, backward and forward linkage impacts are calculated along the waterfront where the auto industry is concentrated. In addition, economic damage from natural disasters is estimated. We assess the economic implications on the hinterland of Mikawa Port. Density functions of the backward and forward linkage impacts are derived. A production stoppage along the waterfront of Mikawa Port generates large indirect negative effects on the regional economy. Results found that density functions of the total impacts are decreasing function of distance but that several sectors are characterized by non-decreasing functions.

On March 11, 2011, Japan was struck by a massive earthquake and tsunami. The tsunami caused tremendous damage and traumatized a number of people, including children. This study aimed to compare traumatic symptoms and daily life activity among children 20 months after the 2011 Great East Japan Earthquake and Tsunami with those observed after 8 months. The study comprised two groups. The first comprised 12,524 kindergarten, elementary school, and junior high school children in Ishinomaki City, Miyagi Prefecture, Japan, who were evaluated 8 months after the disaster. The second comprised 10,597 children from the same place who were evaluated 20 months after the disaster. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a questionnaire on children's daily life were distributed to the children. An effective response was obtained from 11,639 (92.9%, 8 months after) and 10,597 (86.9%, 20 months after) children. The PTSSC-15 score was significantly higher in junior high school girls than in boys. The PTSSC-15 score was significantly higher in 4th-6th grade girls than in boys after 8 months. Elementary and junior high school children evaluated after 20 months had a significantly lower PTSSC-15 score than those evaluated after 8 months. The number of children having breakfast was significantly higher after 8 months than that after 20 months. In both the groups, children of all grades who had breakfast had a significantly lower PTSSC-15 score than those who did not have breakfast. We conclude that traumatic symptoms and daily life activity of children who survived the earthquake and tsunami improved over time.

[Maternal filicide in Japan: analyses of 96 cases and future directions for prevention].

Maternal filicide is not an isolated phenomenon. When a mother kills her child, she may be affected by many factors and confronted with different problems based on the child's developmental stage. In this study in Japan, a judicial sample of 96 adult women, convicted in their first trial for the murder or attempted murder of their children, was divided into four groups of mothers according to the age of the victim (25 women killed neonates, 22 women infants, 27 women preschool children, and 22 women schoolchildren and/or teenagers) in order to identify the factors that have a major impact on filicide in each group. The socio-demographic, clinical, forensic, circumstantial, and offense characteristics, and legal disposition of 96 cases drawn from judicial records were compared among the four groups using the Kruskal-Wallis test; comparison of two groups was conducted using the Mann-Whitney test. Neonaticide cases were distinguished from the other three groups by marked differences: a significantly higher rate of unmarried mothers, financial difficulties, absence of mental illness, and admission of not wanting an illegitimate child. In the other groups, mental disorders were frequent; in particular, post-partum depression was the primary cause of infanticide. For the two groups of cases involving a child older than one year, filicidal mothers were more affected by circumstantial factors such as health problems of the child or severe marital discord. These problems may then have caused a reactive mental disorder among these mothers. The risk of fatal abuse or neglect was higher for handicapped preschool children. Filicide-suicide was most frequently seen among school-aged children and/or teenagers who had serious behavioral problems, and these children often had a mental disorder. The classification of maternal filicide by age of the child demonstrated that there are specific issues for each group. Based on these findings, future directions for prevention include

Foot-and-mouth disease (FMD) occurred in Miyazaki, Japan, in 2010, and 290,000 animals were culled. This paper describes the mental distress of the volunteers who had been dispatched to Miyazaki for disease control two years after the epidemic. It also assesses risk factors for post-traumatic stress disorder (PTSD). A participatory appraisal and self-administered questionnaire survey were conducted in 2012 for those who were dispatched to Miyazaki in 2010. The Impact of Event Scale-Revised (IES-R) was used as an indicator of PTSD, and univariate and multivariable analyses were performed. Of the 875 respondents, 1.3% had higher IES-R scores than the cut-off point (25), which is suggestive of PTSD. Mental stresses during and soon after FMD control and after two years were described. Four risk factors associated with high IES-R scores were found: transporting culled animals (P<0.01), stress during FMD control (P<0.01) and at the time of the survey (P<0.01), and lack of someone to talk to about FMD-associated stress at the time of the survey (P<0.01). Veterinarians, livestock technicians and clerical officers involved in FMD control still suffer from mental stress two years later. Public services should provide an opportunity for them to consult with mental health specialists. These findings should be used to better prepare workers who deal with infectious diseases of animals, especially when they must be culled. The establishment of a collaborative framework between veterinary and mental health services is recommended.

After being introduced to Japan, the Chinese acupuncture and massage therapy has changed a lot, in which the influence aroused by the blind practitioners cannot be ignored. Through analyzing the development and the transition of the blind acupuncture and massage industry in Japan, it is found that the tube needle technique, changeable acupoints concept, technical deviation and the importance on acupoints rather than meridians are still existed commonly today, which are introduced by the blind acupuncture and massage practitioners, the special group in Japan. In the process of development, the interaction with the governmental strategy has played the essential role in the consolidation of the above features.

Drastic shift of lava geochemistry between pre- and post- Japan Sea opening in NE Japan subduction zone: constraints on source composition and slab surface melting processes

Isotopic and trace element data imply a temporal change in magma sources and thermal conditions beneath the northern Fossa Magna, NE Japan arc from the Oligocene to the Pleistocene. Less radiogenic 176Hf/177Hf and 143Nd/144Nd, and high Zr/Hf characterize the Oligocene - Early Miocene volcanism in the northern Fossa Magna region. The mantle wedge in the Oligocene - Early Miocene consisted of enriched mantle source. We propose that during the onset of subduction, influx of hot asthenospheric mantle provided sufficient heat to partially melt newly subducting sediment. Geochemical modeling results suggest breakdown of zircon in the slab surface sediments for the Oligocene - Early Miocene lavas in the northern Fossa Magna region. In the Middle Miocene, the injection of hot and depleted asthenospheric material replaced the mantle beneath the northern Fossa Magna region of NE Japan. The Middle Miocene lavas characterized by most radiogenic Hf and Nd isotope ratios, have high Zr/Hf. An appropriate working petrogenetic model is that the Middle Miocene lavas were derived from asthenospheric depleted mantle, slightly (<1%) contaminated by slab melt accompanied by full dissolution of zircon. All the Late Miocene - Pleistocene samples are characterized by distinctly more radiogenic 176Hf/177Hf and 143Nd/144Nd, and are displaced toward lower Zr/Hf, which requires mixing between depleted mantle and a partial melt of subducted metasediment saturated with trace quantity of zircon. The Oligocene - Early Miocene volcanism in the northern Fossa Magna region may represent the early stage of continental margin magmatism associated with a back-arc rift. Here volcanism is dominated by sediment melts. Perhaps asthenospheric injection, triggering Japan Sea opening, allowed higher temperatures and more melting at the slab-mantle interface. The mantle wedge was gradually cooled during the Middle Miocene to the Pleistocene with back-arc opening ending in the Late Miocene. Slab surface

This study examined the therapeutic effects of Life Review processes on physical and psychological functions of homebound elderly in Japan. From 1998, a cohort of people aged 65 and over living in two cities in Yamagata Prefecture has been followed. Sixty-three subjects (24 men, 39 women) were classified as rank A (homebound). Fifty-two persons completed the baseline survey in 1999 and 46 eligible persons (18 men and 28 women) were allocated to intervention and control groups whose age and sex distribution were matched. Intervention entailed giving some health information and Life Review processing for four months, twice a month on average. Each session started with provision of health information followed by the Life Review process which took an hour to finish. All subjects of both groups were assessed for dependent variables at the beginning and the end of the intervention period (pretest and post-test). Dependent variables were physical (Activities of Daily Living, Visual deficit, and others), psychological (subjective health, life satisfaction, self-efficacy scale, and others), and social (functional ability and frequency of getting out of the house). The control group received only the pretest and the post-test. Pretest scores for all physical, psychological, and social variables did not significantly differ between the two groups. The rate for improvement/no change were higher with regard to hearing deficit, ADL (eating, dressing), cognition, subjective health, ikigai and frequency of getting out of house in the intervention group than in the control group, but there were no significant differences. The developed intervention program featuring delivery of health information and structured Life Review Process had no negative influence on physical and psycho-social functions. Practicability of the intervention was suggested. But the study highlights problems such as selection of subjects, duration and method of intervention.

Flippin' Fluid Mechanics - Quasi-experimental Pre-test and Post-test Comparison Using Two Groups

Webster, D. R.; Majerich, D. M.; Luo, J.

2014-11-01

A flipped classroom approach has been implemented in an undergraduate fluid mechanics course. Students watch short on-line videos before class, participate in active in-class problem solving (in dyads), and complete individualized on-line quizzes weekly. In-class activities are designed to achieve a trifecta of: 1. developing problem solving skills, 2. learning subject content, and 3. developing inquiry skills. The instructor and assistants provide critical ``just-in-time tutoring'' during the in-class problem solving sessions. Comparisons are made with a simultaneous section offered in a traditional mode by a different instructor. Regression analysis was used to control for differences among students and to quantify the effect of the flipped fluid mechanics course. The dependent variable was the students' combined final examination and post-concept inventory scores and the independent variables were pre-concept inventory score, gender, major, course section, and (incoming) GPA. The R-square equaled 0.45 indicating that the included variables explain 45% of the variation in the dependent variable. The regression results indicated that if the student took the flipped fluid mechanics course, the dependent variable (i.e., combined final exam and post-concept inventory scores) was raised by 7.25 points. Interestingly, the comparison group reported significantly more often that their course emphasized memorization than did the flipped classroom group.

We investigated the incidence of fragility fractures from 2010 to 2012 in Sakaiminato, Japan. The incidence rates of limb fractures in Sakaiminato were lower than in Caucasian populations but had increased relative to data obtained in Japan in the 1990s. Clinical vertebral fractures occurred at higher rates in Sakaiminato than in Caucasian populations. To elucidate the incidence and prognosis of fragility fractures in Sakaiminato, Japan. A survey of all hip, distal radius, proximal humerus, and clinical vertebral fractures was performed from 2010 to 2012 in patients aged 50 or older in Sakaiminato city, Tottori prefecture, Japan. The age- and gender-specific incidence rates (per 100,000 person-years) were calculated based on the population of Sakaiminato city each year. The incidence rates of hip, distal radius, and proximal humerus fractures were compared with previous reports. We conducted a follow-up study assessing patients within 1 year following their initial treatment at two Sakaiminato hospitals. The age-adjusted incidence rates in population aged 50 years or older (per 100,000 person-years) of hip, distal radius, proximal humerus, and clinical vertebral fractures were, respectively, 217, 82, 26, and 412 in males and 567, 432, 96, and 1229 in females. Age-specific incidence rates of hip, distal radius, and proximal humerus fractures all increased since the 1990s. Our study also revealed that anti-osteoporotic pharmacotherapy was prescribed 1 year post-fracture at rates of 29, 20, 30, and 50 % for patients with hip, distal radius, proximal humerus, and clinical vertebral fractures, respectively. The incidence rates of limb fractures in Sakaiminato were substantially lower than Caucasian populations in northern Europe but had increased relative to data obtained in Japan in the 1990s. Unlike upper and lower limb fractures, clinical vertebral fractures occurred at higher rates in our study population than in other Asian and North European countries.

Child poverty is a growing, serious issue in Japan, where various social disparities are increasing. Numerous reports have focused on the relationship between social inequity and health, but few studies have assessed how the overall magnitude of disparities in child health has changed in the course of drastic social and economic transitions from 1899 to more recent times. In this study, we assessed the trend of the under-5 mortality rate (U5MR) and its inter-prefecture disparity in Japan. This is a secondary analysis of Japan's vital statistics data from 1899 to 2014 (115 years), which covers a core period of modern Japan. We calculated the U5MR of each prefecture and its Theil index by year to assess the trend of inter-prefecture disparity in child health from 1899 to 2014. The U5MR monotonically decreased from 238 per 1,000 births in 1899 to 3 in 2014. The Theil index of the U5MR increased in the post-war period, peaked in 1962 (0.027) and gradually reduced to <0.01 in the 1970s. In the 2000s, however, even though U5MR continued to decrease, the Theil index started to increase, and in 2014 (0.013) it exceeded that in 1970 and was more similar to that before World War II. The disparities in child health appear to be widening, and may serve as a warning to today's society that increasing socioeconomic gradients may lead to rising health inequity among children. Further investigations into the causes, mechanisms, and possible interventions are needed. © 2017 Japan Pediatric Society.

Although attention has been paid to post-traumatic stress disorder (PTSD) among health care professionals after disasters, the impact of traumatic events on their work has not been elucidated. The aim of this study was to examine whether disaster-related distress, resilience, and post-traumatic growth (PTG) affect work engagement among health care professionals who had been deployed to the areas affected by the Great East Japan Earthquake that occurred on March 11, 2011. We recruited disaster medical assistance team members who were engaged in rescue activities after the earthquake. The short version of the Resilience Scale (RS-14) and Peritraumatic Distress Inventory (PDI) were administered one month after the earthquake, and the short form of Posttraumatic Growth Inventory (SF-PTGI) and Utrecht Work Engagement Scale (UWES) were administered four years after the earthquake. Work engagement is composed of vigor, dedication, and absorption. Regression analyses were used to examine the relationship of UWES with RS-14, PDI, and SF-PTGI. We obtained baseline data of 254 participants in April 2011, and 191 (75.2%) completed the follow-up assessment between December 2014 and March 2015. The results showed that RS-14 predicted vigor, dedication, and absorption; in addition, SF-PTGI was positively related with these three parameters (p<0.01 for all). Resilience at baseline and PTG after rescue activities may increase work engagement among health care professionals after disasters. These findings could be useful for establishing a support system after rescue activities during a large-scale disaster and for managing work-related stress among health care professionals.

The March 2011 "triple disaster" (earthquake, tsunami, and nuclear accident) had a profound effect on northern Japan. Many medical students at Fukushima Medical University volunteered in the relief effort. We aimed to investigate the nature of students' post-disaster involvement and examine the psychological impact of their experiences using a survey containing elements from the Davidson Trauma Scale and Posttraumatic Growth Inventory. We collected 494 surveys (70 % response rate), of which 132 students (26.7 %) had volunteered. Volunteers were more likely to be older, have witnessed the disaster in person, had their hometowns affected, and had a family member or close friend injured. In the month after 3/11, volunteers were more likely to want to help, feel capable of helping, and report an increased desire to become a physician. Both in the month after 3/11 and the most recent month before the survey, there were no significant differences in distressing symptoms, such as confusion, anger, or sadness, between volunteers and non-volunteers. Volunteers reported a significantly higher level of posttraumatic growth than non-volunteers. Participating in a greater variety of volunteer activities was associated with a higher level of posttraumatic growth, particularly in the Personal Strength domain. There may be self-selection in some criteria, since students who were likely to be resistant to confusion/anxiety/sadness may have felt more capable of helping and been predisposed to volunteer. However, participation in post-disaster relief efforts did not appear to have a harmful effect on medical students, an important consideration for mobilizing volunteers after future disasters.

Psychological trauma after the Great East Japan Earthquake.

The Great East Japan Earthquake (GEJE) struck the northeastern part of Japan on 11 March 2011 and triggered a devastating tsunami, causing widespread destruction along the coast of northeastern Japan. The tsunami also led to an accident at the Fukushima Daiichi nuclear power plant. Incidents occurring in such major disasters are known to lead to psychological trauma. This paper has summarized English-language documentation regarding GEJE-related psychological trauma or post-traumatic stress disorder (PTSD). Research thus far has reported the possibility of higher probable PTSD prevalence among residents of the GEJE areas than in the average Japanese population during normal times. At the very least, many people have experienced trauma symptoms at self-recognition levels 1 year or longer after the disaster. It appears that the percentage of persons with high PTSD risk was higher in regions with radiation-related impacts than in regions where the main damage was caused by the earthquake and tsunami. Results have not been limited to showing relations between severe exposure to a traumatic event and PTSD symptoms but also show that a variety of factors, including social factors, has been shown to interact with PTSD symptoms. The fact that Japanese society as a whole united against the trauma of the GEJE may have worked to minimize the effects of trauma. To grasp a full picture of the effects of psychological trauma due to the GEJE, further surveys and research are necessary. It will be necessary to continue engagements related to these problems and issues into the future. © 2016 The Authors.

2011-10-01

A recent international Internet-based study of young children (birth to 36 months) found that total sleep duration in Japan was the shortest among 17 countries/regions. The present study compared features of children's sleep in Japan relative to those in other Asian countries/regions. Parents of 872 infants and toddlers in Japan (48.6% boys), and parents of 20 455 infants and toddlers in 11 other Asian countries/regions (48.1% boys; China, Hong Kong, India, Indonesia, Korea, Malaysia, Philippines, Singapore, Taiwan, Thailand, and Vietnam) completed an Internet-based expanded version of the Brief Infant Sleep Questionnaire. Young children in Japan exhibited significantly fewer nocturnal wakings and shorter daytime sleep in comparison with other Asian countries/regions. Although the former finding was apparent in all age groups, the reduced duration of daytime sleep in Japan was not present until after 3 months of age. Interestingly, sleep problems were reported by significantly fewer parents in Japan compared with those in other Asian countries/regions, although parents in Japan reported significantly more difficulty at bedtime. The short sleep duration of young children in Japan is largely due to a relatively short duration of daytime sleep. Significant differences in sleep characteristics in Japan relative to other Asian regions were found primarily after 3 months of age. Future studies should further explore the underlying causes and the potential impacts of these sleep differences. © 2011 The Authors. Pediatrics International © 2011 Japan Pediatric Society.

This retrospective study evaluated treatment outcome of cast post and core and Composipost systems after 4 yrs of clinical service. 200 patients were included in the study. They were divided in two groups of 100 endodontically treated teeth restored with a post. Group 1: Composipost systems were luted into root canal following the manufacturer's instructions. Group 2: Cast post and cores were cemented into root canal preparations with a traditional technique. The patients were recalled after 6 months, 1, 2 and 4 yrs and clinical and radiographic examinations were completed. Endodontic and prosthodontic results were recorded. Group 1: 95% of the teeth restored with Composiposts showed clinical success; 3% of these samples were excluded for noncompliance and 2% showed endodontic failure. Group 2: Clinical success was found with 84% of teeth restored with cast post and core. 2% of these samples were excluded for noncompliance, 9% showed root fracture, 2% dislodgment of crown and 3% endodontic failure. Statistical evaluation showed significant differences between Groups 1 and 2 (P < 0.001). The results of this retrospective study indicated that the Composipost system was superior to the conventional cast post and core system after 4 yrs of clinical service.

Aim: To compare the fracture resistance of teeth restored with fiber-reinforced composite (FRC) posts and experimental dentin posts milled from human root dentin. Materials and Methods: Thirty maxillary central incisors were divided into three groups of ten each. Twenty teeth were restored with FRC posts and solid dentin posts and numbered as Groups 2 and 3 respectively while Group 1 acted as the control, without any post. The teeth were loaded at 135° angle to their long axes after core build-up and the failure loads were recorded. Results: One-way Analysis of Variance (ANOVA) and Bonferroni multiple comparisons revealed a significant difference among test groups with the control group showing the highest fracture resistance, followed by the dentin post group and lastly the FRC post group. Conclusions: Teeth restored with dentin posts exhibited better fracture resistance than those restored with FRC posts. PMID:22144812

Bioresorbable Scaffold for Treatment of Coronary Artery Lesions: Intravascular Ultrasound Results From the ABSORB Japan Trial.

The aim of this study was to characterize post-procedural intravascular ultrasound (IVUS) findings in the ABSORB Japan trial, specifically stratified by the size of target coronary arteries. Despite overall noninferiority confirmed in recent randomized trials comparing bioresorbable vascular scaffolds (BVS) (Absorb BVS) and cobalt-chromium everolimus-eluting metallic stents (CoCr-EES), higher event rates of Absorb BVS have been reported with suboptimal deployment, especially in small coronary arteries. In the ABSORB Japan trial, 150 patients (2:1 randomization) were scheduled in the IVUS cohort. Small vessel was defined as mean reference lumen diameter <2.75 mm. Tapered-vessel lesions were defined as tapering index (proximal/distal reference lumen diameter) ≥1.2. Overall, IVUS revealed that the Absorb BVS arm had smaller device expansion than the CoCr-EES arm did, which was particularly prominent in small- and tapered-vessel lesions. Higher tapering index was also associated with higher rates of incomplete strut apposition in Absorb BVS, but not in CoCr-EES. With respect to procedural techniques, small-vessel lesions were treated more frequently with noncompliant balloons at post-dilatation but using significantly lower pressure in the Absorb BVS arm. In contrast, tapered-vessel lesions were post-dilated at equivalent pressure but with significantly smaller balloon catheters in the Absorb BVS arm, compared with the CoCr-EES arm. The significantly smaller device expansion especially in small vessels may account for the poorer outcomes of Absorb BVS in this lesion type. Appropriate optimization strategy, possibly different between polymeric and metallic devices, needs to be established for bioresorbable scaffold technology.

2014-01-01

The paper examines recent time trends, explores potentially influential background factors and discusses prevention strategies of pregnancy among girls under 15 years of age in Japan. Using Japanese government data, we first analyzed time trends of early adolescence (<15 years of age) abortion, live birth and child sexual abuse from 2003 to 2010. Second, we analyzed ecological correlations of early adolescent pregnancy (abortion, live birth and stillbirth) with pregnancy in other age groups, child sexual abuse, and indicators of juvenile victimization and juvenile delinquency, using prefectural data. We found that rates of both abortion and live birth in early adolescents have increased since 2005 (annual percent change 5.3% and 2.3%, respectively), despite declining rates in older age groups. The abortion ratio in early adolescence remained the highest among all age groups in Japan. The early adolescent pregnancy rate showed significant correlation with the rates of juvenile victimization of welfare crimes (obscenity, alcohol drinking, smoking and drug use) (Spearman's rank correlation coefficient [rs] = 0.42, P = 0.00) and juvenile delinquency among junior high school students (12-14 years of age) (rs = 0.69, P = 0.00). The observed rise in rates of abortion, live birth and child sexual abuse among early adolescents along with strong ecological correlations of their pregnancy rate with juvenile victimization and delinquency indicators suggests that epidemiological investigation and public health programs at the individual and community levels are needed to address the complex social roots of these trends and to produce effective improvements in early adolescent reproductive health. © 2013 The Authors.

The objective of this study was to longitudinally examine the geographic distribution of physicians in Japan with adjustment for healthcare demand according to changes in population age structure. We examined trends in the number of physicians per 100 000 population in Japan's secondary medical areas (SMAs) from 2000 to 2014. Healthcare demand was adjusted using health expenditure per capita. Trends in the Gini coefficient and the number of SMAs with a low physician supply were analysed. A subgroup analysis was also conducted where SMAs were divided into 4 groups according to urban-rural classification and initial physician supply. The time-based changes in the Gini coefficient and the number of SMAs with a low physician supply indicated that the equity in physician distribution had worsened throughout the study period. The number of physicians per 100 000 population had seemingly increased in all groups, with increases of 22.9% and 34.5% in urban groups with higher and lower initial physician supply, respectively. However, after adjusting healthcare demand, physician supply decreased by 1.3% in the former group and increased by 3.5% in the latter group. Decreases were also observed in the rural groups, where the number of physicians decreased by 4.4% in the group with a higher initial physician supply and 7.6% in the group with a lower initial physician supply. Although the total number of physicians increased in Japan, demand-adjusted physician supply decreased in recent years in all areas except for urban areas with a lower initial physician supply. In addition, the equity of physician distribution had consistently deteriorated since 2000. The results indicate that failing to adjust healthcare demand will produce misleading results, and that there is a need for major reform of Japan's healthcare system to improve physician distribution.

The incidence of osteoporosis-related fractures in Asian countries is steadily increasing. Optimizing osteoporosis treatment is especially important in Japan, where the rate of aging is increasing rapidlyelderly population is increasing rapidly and life expectancy is among the longest in the world. There are several therapies currently available in Japan for the treatment of postmenopausal osteoporosis, each with a unique risk/benefit profile. A novel selective estrogen receptor modulator, bazedoxifene (BZA), was recently approved for the treatment of postmenopausal osteoporosis in Japan. Results from a 2-year, phase 2 trial in postmenopausal Japanese women showed that BZA significantly improved lumbar spine and total hip bone mineral density compared with placebo, while maintaining endometrial and breast safety, consistent with results from 2 global, phase 3 trials including a 2-year osteoporosis prevention study and a 3-year osteoporosis treatment study. In the pivotal 3-year treatment study, BZA significantly reduced the incidence of new vertebral fractures compared with placebo; in a post hoc analysis of a subgroup of women at higher risk of fractures, BZA significantly reduced the risk of nonvertebral fractures compared with placebo and raloxifene. A 2-year extension of the 3-year treatment study demonstrated the sustained efficacy of BZA over 5 years of treatment. BZA was generally safe and well tolerated in these studies. In a "super-aging" society such as Japan, long-term treatment for postmenopausal osteoporosis is a considerable need. BZA may be considered as a first choice for younger women anticipating long-term treatment, and also an appropriate option for older women who are unable or unwilling to take bisphosphonates.

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.

Following the modern raising of public awareness, the numbers of malpractice litigation are increasing in the health care delivery system in Japan despite the extensive efforts of physicians. Authors reviewed the issues of litigation and the reasons for court decision from the healthcare-related negligence lawsuits in the past 15 years in Japan and investigated the cautionary points for reducing potential litigation. Healthcare-related negligence lawsuits between January 2001 and December 2015 were retrieved and sorted in each clinical field from the database in Courts in Japan and investigated on the proportional factors of the claims and court decisions in the neurosurgical field. During the period, 446 of healthcare-related court decisions including 41 against neurosurgeons (9.2%) were retrieved. Three of 41 decisions retrieved were decisions to retries for lower court decisions. In 38 claims against the neurosurgeons, 26 identified the negligence and 12 dismissed. In 26 decisions in favor of the plaintiffs, identified negligence in diagnosis in 4, clinical judgment in 3, technical skills in 5, clinical management in 7 and process of informed consent in 7. Five out of 18 decisions after 2006 were identified as negligence in an informed consent process, and additional one, who was mainly identified in inadequate technical skills also identified existing an inadequate informed consent process as a fundamental cause of litigation. Neurosurgeons are a higher risk group for malpractice litigation in Japan and adequate informed consent is important to reduce the risk of litigation.

Characteristics of Wet Deposition in Japan

Acid deposition survey in Japan has started since 1991 by Japan Environmental Laboratories Association (JELA). The JELA has about 60 monitoring sites for wet deposition including remote, rural and urban area. The measured constituents of wet deposition are; precipitation, pH, electric conductivity, major Anions, and major Cations. From those data, we analyze spatial and temporal variations of wet deposition components in Japan. Among the 60 monitoring sites, 39 sampling sites were selected in this study, which have kept sampling continuously between 2003JFY and 2014JFY. All samples were collected by wet-only samplers. To analyze area characteristics, all the areas were divided into 6 regions; Northern part of Japan (NJ), Facing the Japan Sea (JS), Eastern part of Japan (EJ), Central part of Japan (CJ), Western part of Japan (WJ) and Southern West Islands (SW). NO3- and non-sea-salt-SO42- (nss-SO42-) are major components of rain acidification. Especially, between December and February (winter) the air mass from west affected the temporal variations of those acid components and the concentrations were higher in JS and WJ regions than those in other regions. Japanese ministry of the Environment reported that mixing ratio of NO2 in Japan has been less than 0.04ppm since 1976, and that of SO2 has been less than 0.02ppm since 1978. Their concentrations in Japan have remained flat or slowly decreased recently. However the temporal variations of NO3-/nss-SO42- ratio in winter in JS region were significantly increased on average at 2.2% y-1 from 2003JFY to 2014JFY. The results suggest that long-range transboundary air pollutants increased NO3- concentrations and NO3-/nss-SO42- ratio.

Abstract Gastric cancer (GC) remains a major killer throughout the world. Despite the dramatic decrease in GC over the last century, its etiology has not yet been well characterized. This study investigated the possible independent and combined effects of the dinner-to-bed time and post-dinner walk on the risk for GC across different age groups. A population-based, case–control study was conducted in southeast China, including 452 patients with GC and 465 age-, race-, and gender-matched controls. A self-designed questionnaire was used to collect information on demographic characteristics, dinner-to-bed time, post-dinner walk, and other behavioral factors. Conditional logistic regression models were used to estimate the effects of the dinner-to-bed time and post-dinner walk as well as their joint effect on the risk for GC across different age groups. Individuals with dinner-to-bed time <3 hours were more prone to have GC (P < 0.001), and the shorter the dinner-to-bed time was, the higher was the risk for GC (Ptrend < 0.001). Post-dinner nonwalk was associated with a 2.9-fold increased risk for GC compared with post-dinner walk (adjusted odds ratio [AOR] = 2.942, 95% confidence intervals [95% CIs] = 2.072–4.179). The interaction effect of dinner-to-bed time and post-dinner walk on GC risk was detected (AOR = 1.862, 95% CIs = 1.584–3.885, synergy index [SI] = 2.654, 95% CIs = 2.27–3.912). Participants with dinner-to-bed time <3 hours who did not walk after dinner were 7.4 times likely to suffer from GC (AOR = 7.401, 95% CIs = 4.523–13.16) than those with dinner-to-bed time ≥4 hours who took such walk. The risk of GC due to dinner-to-bed time <3 hours, post-dinner nonwalk and their interaction was positively correlated with age. The strongest risk was observed among people ≥70 years old, but the effects were not significant for people ≤55 years old. Dinner-to-bed time <3 hours and post-dinner nonwalk are

Purpose: To determine the patterns of radiotherapy practice for pancreatic cancer in Japan. Methods and Materials: A questionnaire-based national survey of radiotherapy for pancreatic cancer treated between 2000 and 2006 was conducted by the Japanese Radiation Oncology Study Group (JROSG). Detailed information on 870 patients from 34 radiation oncology institutions was accumulated. Results: The median age of all patients was 64 years (range, 36-88), and 80.2% of the patients had good performance status. More than 85% of patients had clinical Stage T3-T4 disease, and 68.9% of patients had unresectable disease at diagnosis. Concerning radiotherapy (RT), 49.8% of patients were treatedmore » with radical external beam RT (EBRT) (median dose, 50.4 Gy), 44.4% of patients were treated with intraoperative RT (median dose, 25 Gy) with or without EBRT (median dose, 45 Gy), and 5.9% of patients were treated with postoperative radiotherapy (median dose, 50 Gy). The treatment field consisted of the primary tumor (bed) only in 55.6% of the patients. Computed tomography-based treatment planning and conformal RT was used in 93.1% and 83.1% of the patients treated with EBRT, respectively. Chemotherapy was used for 691 patients (79.4%; before RT for 66 patients; during RT for 531; and after RT for 364). Gemcitabine was the most frequently used drug, followed by 5-fluorouracil. Conclusion: This study describes the general patterns of RT practice for pancreatic cancer in Japan. Most patients had advanced unresectable disease, and radical EBRT, as well as intraoperative RT with or without EBRT, was frequently used. Chemotherapy with gemcitabine was commonly used in conjunction with RT during the survey period.« less

This investigation sought to compare the fracture resistance under static and fatigue loading of endodontically treated teeth restored with fiber-reinforced composite posts and experimental dentin posts milled from human root dentin by using computer-aided design/computer-aided manufacturing. Seventy maxillary central incisors were obturated and divided into 4 groups: control group without any post (n = 10), carbon fiber post group (n = 20), glass fiber post group (n = 20), and dentin post group (n = 20). Control group teeth were prepared to a height of 5 mm. In all other teeth, post space was prepared; a post was cemented, and a core build-up was provided. Half the samples from each group were statistically loaded until failure, and the remaining half were subjected to cyclic loading, followed by monostatic load until fracture. One-way analysis of variance and Bonferroni multiple comparisons revealed a significant difference among test groups. The control group demonstrated highest fracture resistance (935.03 ± 33.53 N), followed by the dentin post group (793.12 ± 33.69 N), glass fiber post group (603.44 ± 46.67 N), and carbon fiber post group (497.19 ± 19.27 N) under static loading. These values reduced to 786.69 ± 29.64 N, 646.34 ± 26.56 N, 470 ± 36.34 N, and 379.71 ± 13.95 N, respectively, after cyclic loading. Results suggest that human dentin can serve as post material under static and fatigue loading. Although at an early stage in research, the use of dentin posts in root-filled teeth looks promising.

Tummala, Rao R.; Pecht, Michael

The JTEC panel found Japan to have significant leadership over the United States in the strategic area of electronic packaging. Many technologies and products once considered the 'heart and soul' of U.S. industry have been lost over the past decades to Japan and other Asian countries. The loss of consumer electronics technologies and products is the most notable of these losses, because electronics is the United States' largest employment sector and is critical for growth businesses in consumer products, computers, automobiles, aerospace, and telecommunications. In the past there was a distinction between consumer and industrial product technologies. While Japan concentrated on the consumer market, the United States dominated the industrial sector. No such distinction is anticipated in the future; the consumer-oriented technologies Japan has dominated are expected to characterize both domains. The future of U.S. competitiveness will, therefore, depend on the ability of the United States to rebuild its technological capabilities in the area of portable electronic packaging.

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.

In 2009, the Japan Anti-Doping Agency (JADA) established the "Sports Pharmacist Accreditation Program" to prevent doping in sports. Since then, anti-doping activities in Japan have been attracting attention. In this study, we investigated research about the current status of doping from 2007 to 2014 in Japan to make anti-doping activities more concrete, and we also discussed future anti-doping activities by pharmacists. In Japan, bodybuilding was the sporting event with the highest number and rate of doping from 2007 to 2014. Many of the positive doping cases were detected for class S1 (anabolic agents), S5 (diuretics and masking agents), and S6 (stimulants). Within class S1, supplements were the main cause of positive doping. Within class S5, medicines prescribed by medical doctors were the main cause of positive doping. Within class S6, non-prescription medicines (e.g., OTC) were the main cause of positive doping. When we looked at the global statistics on doping, many of the positive doping cases were detected for class S1. On comparing the Japanese statistics with the global statistics, the rate of positive doping caused by class S1 was significantly lower, but that caused by classes S5 and S6 was significantly higher in Japan than in the world. In conclusion, pharmacists in Japan should pay attention to class S1, S5, and S6 prohibited substances and to the sport events of bodybuilding. Based on this study, sports pharmacists as well as common pharmacists should suggest new anti-doping activities to prevent doping in the future.

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.

To explore the potential factors impacting the efficacy of venlafaxine extended release (ER) and treatment differences between 75 mg/day and 75-225 mg/day dose in patients with major depressive disorder (MDD). We performed exploratory post hoc subgroup analyses of a randomized, double-blind, placebo-controlled study conducted in Japan. A total of 538 outpatients aged 20 years or older with a primary diagnosis of MDD who experienced single or recurrent episodes were randomized into three groups: fixed-dose, flexible-dose, or placebo. Venlafaxine ER was initiated at 37.5 mg/day and titrated to 75 mg/day for both fixed-dose and flexible-dose group, and to 225 mg/day for flexible-dose group (if well tolerated). Efficacy endpoints were changes from baseline at Week 8 using the Hamilton Rating Scale for Depression-17 items (HAM-D 17 ) total score, Hamilton Rating Scale for Depression-6 items score, and Montgomery-Asberg Depression Rating Scale total score. The following factors were considered in the subgroup analyses: sex, age, HAM-D 17 total score at baseline, duration of MDD, duration of current depressive episode, history of previous depressive episodes, history of previous medications for MDD, and CYP2D6 phenotype. For each subgroup, an analysis of covariance model was fitted and the adjusted mean of the treatment effect and corresponding 95% CI were computed. Due to the exploratory nature of the investigation, no statistical hypothesis testing was used. Venlafaxine ER improved symptoms of MDD compared with placebo in most subgroups. The subgroup with a long duration of MDD (>22 months) consistently showed greater treatment benefits in the flexible-dose group than in the fixed-dose group. These results suggest that a greater treatment response to venlafaxine ER (up to 225 mg/day) can be seen in patients with a longer duration of MDD. Further investigations are needed to identify additional factors impacting the efficacy of venlafaxine ER.

To elucidate relationships between disaster damage conditions and sleep duration among children who survived the 2011 Japan earthquake and tsunami. The subjects comprised 12,524 children in kindergartens, elementary schools, and junior high schools in Ishinomaki City, Miyagi Prefecture, Japan. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a sleep questionnaire were distributed to them. A questionnaire regarding disaster damage conditions of the children's homes was distributed to their teachers. Of 12,524, an effective response was obtained from 11,692 (93.3%). Relationships between sleep duration and traumatic symptoms were displayed low correlations. Children with house damage and/or evacuation experiences slept for a significantly shorter time than children without these experiences. It is critical not only to examine traumatic symptoms in children but also to collect sleep duration and disaster damage conditions following natural disasters.

Background On March 11, 2011, Japan was struck by a massive earthquake and tsunami. The tsunami caused tremendous damage and traumatized a number of people, including children. This study aimed to compare traumatic symptoms and daily life activity among children 20 months after the 2011 Great East Japan Earthquake and Tsunami with those observed after 8 months. Methods The study comprised two groups. The first comprised 12,524 kindergarten, elementary school, and junior high school children in Ishinomaki City, Miyagi Prefecture, Japan, who were evaluated 8 months after the disaster. The second comprised 10,597 children from the same place who were evaluated 20 months after the disaster. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a questionnaire on children's daily life were distributed to the children. An effective response was obtained from 11,639 (92.9%, 8 months after) and 10,597 (86.9%, 20 months after) children. Results The PTSSC-15 score was significantly higher in junior high school girls than in boys. The PTSSC-15 score was significantly higher in 4th–6th grade girls than in boys after 8 months. Elementary and junior high school children evaluated after 20 months had a significantly lower PTSSC-15 score than those evaluated after 8 months. The number of children having breakfast was significantly higher after 8 months than that after 20 months. In both the groups, children of all grades who had breakfast had a significantly lower PTSSC-15 score than those who did not have breakfast. Conclusions We conclude that traumatic symptoms and daily life activity of children who survived the earthquake and tsunami improved over time. PMID:24586427

Historically, the progress of long term-oxygen therapy (LTOT) in Japan has been characterized by collaboration among academic groups, policy makers, and industrial companies. The public health insurance program has covered the cost of LTOT since 1985. Thomas Petty's group in Denver enthusiastically carried out the public implementation of LTOT and conveyed the concept of pulmonary rehabilitation for the processing with LTOT. Although the target diseases of LTOT in Japan tended to be chronic obstructive pulmonary disease or sequelae of primary lung tuberculosis, it was soon applied for cardiac diseases as well as other pulmonary diseases. Together with increasing medical costs for geriatric patients, the political conversion from hospital based care of a traditional style to home care system has been performed, with two background reasons: the improvement of quality of life of patients and the reduction of the medical expense. Presently, LTOT plays a pivotal role in the successful implementation of home respiratory care for elderly patients. In addition, this promotes comprehensive pulmonary rehabilitation, a team approach, and close liaisons between primary care and hospitals. Currently, the total number of patients using LTOT exceeds 150,000. In Japan, LTOT resulted in an advancement in the medical care as well as in administrative decision to introduce it as a nationwide system after analyzing the results of opinion polls of patients with respiratory failure. However, the recent great earthquake in East Japan revealed that many unresolved problems remain for these patients, and these issues are of great concern.

Problems on groundwater contamination in Japan are briefly summarized in this paper. Although normal physical conditions in Japan restrict the possibilities of groundwater contamination, human activities are threatening groundwater resources. A survey by the Environment Agency of Japan showed nationwide spreading of organic substances, such as trichloroethylene as well as nitrogen compounds. Synthetic detergents have also been detected even in rural areas and in deep confined aquifers, although their concentrations are not as high. Public awareness of agrichemical or pesticides abuse, especially from golf courses, is apparent. Other problems such as nitrate-nitrogen, leachate from landfills, and the leaking of underground storage tanks are also discussed.

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.

A standardized definition of post-hepatectomy haemorrhage (PHH) has not yet been established. An international study group of hepatobiliary surgeons from high-volume centres was convened and a definition of PHH was developed together with a grading of severity considering the impact on patients' clinical management. The definition of PHH varies strongly within the hepatic surgery literature. PHH is defined as a drop in haemoglobin level > 3 g/dl post-operatively compared with the post-operative baseline level and/or any post-operative transfusion of packed red blood cells (PRBC) for a falling haemoglobin and/or the need for radiological intervention (such as embolization) and/or re-laparotomy to stop bleeding. Evidence of intra-abdominal bleeding should be obtained by imaging or blood loss via the abdominal drains if present. Transfusion of up to two units of PRBC is considered as being Grade A PHH. Grade B PHH requires transfusion of more than two units of PRBC, whereas the need for invasive re-intervention such as embolization and/ or re-laparotomy defines Grade C PHH. The proposed definition and grading of severity of PHH enables valid comparisons of results from different studies. It is easily applicable in clinical routine and should be applied in future trials to standardize reporting of complications. © 2011 International Hepato-Pancreato-Biliary Association.

This study aimed to evaluate factors associated with post-traumatic stress disorder (PTSD) symptoms and burnout 4 years after the Great East Japan Earthquake among medical rescue workers in Disaster Medical Assistance Teams (DMATs). We examined participants' background characteristics, prior health condition, rescue work experiences, and the Peritraumatic Distress Inventory (PDI) score at 1 month after the earthquake. Current psychological condition was assessed by the Impact of Event Scale-Revised and Maslach Burnout Inventory administered 4 years after the earthquake. By applying univariate and multivariate linear regression analyses, we assessed the relative value of the PDI and other baseline variables for PTSD symptoms and burnout at 4 years after the earthquake. We obtained baseline data from 254 participants during April 2 to 22, 2011. Of the 254 participants, 188 (74.0%) completed the follow-up assessment. PDI score 1 month after the earthquake was associated with symptoms of PTSD (β=0.35, P<.01) and burnout (β=0.21, P<.01). Stress before deployment was a related factor for burnout 4 years after the earthquake in these medical rescue workers (β=2.61, P<.04). It seems important for DMAT headquarters to establish a routine system for assessing the PDI of medical rescue workers after deployment and screen those workers who have high stress prior to deployment (Disaster Med Public Health Preparedness. 2016;10:848-853).

Background: Climateric is considered to be a natural phase of life which by definition is the period of life starting from decline in ovarian activity until after the end of ovarian function. It is accompanied by various health consequences that include the changes in saliva too. This study was carried out to evaluate the salivary flow rate, pH, buffering capacity in pre-menopausal, post-menopausal and post-menopausal women on HRT. Aims and objectives: (1) To evaluate the salivary flow rate, pH of resting saliva and stimulated saliva and buffer capacity of stimulated saliva in pre-menopausal, post-menopausal and post-menopausal women on Hormone Replacement Therapy (HRT). (2) To compare the above salivary findings between pre-menopausal, post-menopausal and post-menopausal women on HRT. Materials and Methods: The study was carried out on 60 patients. These patients were divided into three groups of 20 patients: Group 1: Pre-menopausal women (control), Group 2: post-menopausal women (case), Group 3: post-menopausal women on HRT (case). The control group consisted of 20 women volunteers, having regular ovulatory menstrual cycles with no known systemic illness and deleterious habits and Group 2 consists of 20 post-menopausal women and Group 3 will consist of 20 post-menopausal women on HRT. After clearing the mouth by swallowing, stimulated saliva was collected after chewing paraffin for 10 mins in to a glass centrifuge tube graded in 0.1 mL increments up to 10mL.in rare cases the collection time will be reduced or extended (5-15 min), salivary flow rate will be determined as ml/min, immediately after collection, pH was determined by dipping pH test paper directly into the sample of oral fluid, salivary buffer capacity was determined by using saliva check buffer kit (GC corporation).

Whistleblowing in Japan.

Davis, Anne J; Konishi, Emiko

2007-03-01

This article, written from research data, focuses on the possible meaning of the data rather than on detailed statistical reporting. It defines whistleblowing as an act of the international nursing ethical ideal of advocacy, and places it in the larger context of professional responsibility. The experiences, actions, and ethical positions of 24 Japanese nurses regarding whistleblowing or reporting a colleague for wrongdoing provide the data. Of these respondents, similar in age, educational level and clinical experience, 10 had previously reported another nurse and 12 had reported a physician for a wrongful act. These data raise questions about overt actions to expose a colleague in a culture that values group loyalty and saving face. Additional research is needed for an in-depth understanding of whistleblowing, patient advocacy and professional responsibility across cultures, especially those that value group loyalty, saving face and similar concepts to the Japanese Ishin Denshin, where the value is on implicit understanding requiring indirect communication. Usually, being direct and openly discussing sensitive topics is not valued in Japan because such behavior disrupts the most fundamental value, harmony (wa).

Japan’s wolves were extinct by 1905. Today Japan's mountain forests are being killed by overabundant sika deer and wild boars. Since the early 1990s, the Japan Wolf Association has proposed wolf reintroduction to Japan to restore rural ecology and to return a culturally important animal. In this article I discuss whether the return of wolves could help save Japan's mountain forests.

The aim of this study was to investigate the effects of pretreatment of gel chlorhexidine and ethanol on the bond strength and durability of the adhesion of the fiber post relined with resin composite to the root dentin. Sixty bovine incisor roots were divided into four groups: irrigation with physiologic solution (control), 5 minutes with chlorhexidine, 1 minute with ethanol, and 5 minutes with chlorhexidine followed by 1 minute with ethanol. Fiber posts relined with resin composite were cemented with RelyX ARC (3M ESPE, St Paul, MN) and a self-etching adhesive system Clearfil SE Bond (Kuraray, Kurashiki, Japan). Each group was randomly divided into three subgroups: 24 hours of water storage, 12 months of water storage, and 12 months of oil storage. All roots were sectioned transversely in the coronal, middle, and apical regions, producing 1-mm thick slices, and the push-out test was performed. Statistical analysis was performed using analysis of variance and the Tukey test for post hoc comparisons (α = 0.05). Immediate groups showed similar bond strength values with or without chlorhexidine and/or ethanol pretreatment (P > .05). A significant decrease in the bond strength in the control group was observed after 12 months of storage in water and oil (P < .05). The use of chlorhexidine- and/or ethanol-preserved bond strength in the groups stored in water and oil for 12 months (P < .05). Chlorhexidine and/or ethanol pretreatment were capable of preserving the bond strength of the fiber post relined with resin composite to root dentin for 12 months.

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.

There is no official recommendations for physical activity level or steps for preventing and improving child obesity in Japan. Three hundred and two Japanese children aged 9-12 years were recruited wore 3-D speed sensors. Subjects were divided into two groups using the criteria for child obesity in Japan. Body composition was measured on bioelectrical impedance analysis. Physical fitness test was done to evaluate physical strength. Twenty-four hour total steps, energy expenditure, and metabolic equivalents (MET) from Monday to Sunday were consecutively measured. The cut-offs for steps and physical activity level for preventing child obesity were evaluated on receiver operating characteristic curves. Daily life-related risk factors for child obesity were assessed on logistic regression analysis. In both sexes, body volume; bodyweight, body mass index, fat mass, and percentage body fat in the obese group was significantly higher than in the normal group, but age and height were not different (P < 0.001). Aerobic power, running speed, and explosive strength in the obese group were inferior to those in the normal group (P < 0.001). More than 40 min of 4 MET exercise, defined as moderate-vigorous exercise, and 11,000 steps per day are essential to prevent child obesity. Additionally, >2 h TV viewing per day is a significant risk factor for child obesity (OR, 3.43; 95%CI: 1.27-9.31). Cut-offs for physical activity and potential risk factors for child obesity have been identified. Recommendations for changes to daily lifestyle for school-aged Japanese children are given. © 2014 Japan Pediatric Society.

Objectives: Although attention has been paid to post-traumatic stress disorder (PTSD) among health care professionals after disasters, the impact of traumatic events on their work has not been elucidated. The aim of this study was to examine whether disaster-related distress, resilience, and post-traumatic growth (PTG) affect work engagement among health care professionals who had been deployed to the areas affected by the Great East Japan Earthquake that occurred on March 11, 2011. Methods: We recruited disaster medical assistance team members who were engaged in rescue activities after the earthquake. The short version of the Resilience Scale (RS-14) and Peritraumatic Distress Inventory (PDI) were administered one month after the earthquake, and the short form of Posttraumatic Growth Inventory (SF-PTGI) and Utrecht Work Engagement Scale (UWES) were administered four years after the earthquake. Work engagement is composed of vigor, dedication, and absorption. Regression analyses were used to examine the relationship of UWES with RS-14, PDI, and SF-PTGI. Results: We obtained baseline data of 254 participants in April 2011, and 191 (75.2%) completed the follow-up assessment between December 2014 and March 2015. The results showed that RS-14 predicted vigor, dedication, and absorption; in addition, SF-PTGI was positively related with these three parameters (p<0.01 for all). Conclusions: Resilience at baseline and PTG after rescue activities may increase work engagement among health care professionals after disasters. These findings could be useful for establishing a support system after rescue activities during a large-scale disaster and for managing work-related stress among health care professionals.

The prevalence of Helicobacter pylori infection is gradually decreasing in Japan. On the main island of Japan, nearly all H. pylori isolates possess cagA and vacA with strong virulence. However, less virulent H. pylori strains are frequently found in Okinawa where cases of gastric cancer are the lowest in Japan. Eradication therapy for peptic ulcer, idiopathic thrombocytopenic purpura, gastric mucosa-associated lymphoid tissue lymphoma and early gastric cancer after endoscopic resection has been approved by the Japanese national health insurance system. However, the Japanese Society for Helicobacter Research recently stated that all ‘H. pylori infection’ was considered as the indication for eradication irrespective of the background diseases. To eliminate H. pylori in Japan, the Japanese health insurance system should approve the eradication of all H. pylori infections. PMID:23265147

The purpose of this study was to evaluate the time needed to remove several types of fiber posts using two different bur kits. Estimates refer to the time needed to pass the fiber post until arriving at the gutta-percha. Sixty extracted anterior teeth were treated endodontically. A post space with a standard depth of 10 mm was prepared in each root canal. The sample was randomly divided into 3 groups of 20 specimens each. Three different types of posts were cemented: group 1, Conic 6% tapered fiber posts (Ghimas); group 2, FRC Poster fiber posts (Ivoclar-Vivadent); and group 3, Composipost carbon fiber posts (RTD). To remove the post, for half of each group's specimens the burs from the RTD fiber posts removal kit were used (subgroup A). From the other half of the teeth in each group (subgroup B), posts were removed by using a diamond bur and a Largo bur. Composipost carbon fiber posts (group 3) took significantly less time to remove than the other two types of posts (p < 0.05). For the bur kits, the procedure involving the use of a diamond and a Largo bur (subgroup B) was significantly faster (p < 0.05). The interaction between the type of post and the type of bur kit used was not significant (p > 0.05).

In Japan, the Vaccine Epidemiology Research Group created by the Ministry of Health, Labour and Welfare has played an important role in demonstrating the solid scientific basis for vaccine efficacy and safety since 2002. Members of the group, including epidemiologists, clinicians and microbiologists, have been conducting collaborative studies on vaccines for influenza, pertussis, rotavirus gastroenteritis, polio and pneumonia. So far, the group has achieved several works and contributed to the national vaccination program, including research on the immunogenicity of low doses of influenza vaccine among young children, the immunogenicity and effectiveness of the 2009 influenza pandemic vaccine among various risk groups, the interchangeability of live/inactivated polio vaccines, the health impact of influenza on pregnant women, and the monitoring of influenza vaccine effectiveness using case-control studies with a test-negative design. As part of the 18th Annual Meeting of the Japanese Society of Vaccinology, these accomplishments were featured in the Vaccine Epidemiology Symposium. This report summarizes the recent epidemiological studies on vaccine in Japan as a prologue to the next six papers collected from the symposium. Copyright © 2017 Elsevier Ltd. All rights reserved.

Crohn's disease in Japan: diagnostic criteria and epidemiology.

New diagnostic criteria for Crohn's disease and a review of Japanese epidemiologic studies are presented. New diagnostic criteria for Crohn's disease were established by the Research Committee of Inflammatory Bowel Disease, set up by the Japanese Ministry of Health and Welfare. For a definite diagnosis one of the following three conditions is required: 1) longitudinal ulcer or luminal deformity induced by longitudinal ulcer or cobblestone pattern, 2) intestinal small aphthous ulcerations arranged in a longitudinal fashion for at least three months plus noncaseating granulomas, and 3) multiple small aphthous ulcerations in both the upper and lower digestive tract not necessarily with longitudinal arrangement, for at least three months, plus noncaseating granulomas. Moreover, ulcerative colitis, ischemic enterocolitis, and acute infectious enterocolitis should be excluded. Data from the Japanese Ministry of Health and Welfare, in addition to data collected from two study groups, these being the two largest studies in Japan, are reviewed with regard to epidemiology. The number of patients with Crohn's disease has increased remarkably. The prevalence and the annual incidence of patients with Crohn's disease in Japan were estimated to be approximately 2.9 and 0.6 per 10(5) population in 1986, respectively, and 13.5 and 1.2 per 10(5) population in 1998. Characteristic features of Crohn's disease in Japan are that the male-female ratio exceeds 2, and that there is no second peak of incidence in the age group of 55 to 65 years. Clinically, Crohn's disease with only multiple small aphthous ulcerations, which is the earliest stage of the disease that is diagnosable, was found in 5 percent of patients.

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.

The aim of this study was to assess the influence of surface pretreatments of fiber-reinforced posts on flexural strength (FS), modulus of elasticity (ME) and morphology of these posts, as well as the bond strength (BS) between posts and core material. Fifty-two fiber posts (smooth and serrated) were assigned to 4 groups (n=13): no treatment (control), 10% hydrogen peroxide (HP) for 10 min (HP-10), 24% HP for 1 min (HP-24) and airborne-particle abrasion (Al(2)O(3)). To evaluate FS and ME, a 3-point bending test was performed. Three posts of each group were examined by scanning electron microscopy. Composite resin was used as the core build-up and samples were sectioned to obtain microtensile sticks. Data were analyzed by ANOVA and Tukey's test (α=0.05). For FS, significant differences were observed between posts type and surface pretreatment (p<0.05), with the highest means for the smooth posts. Al2O3 provided higher FS than HP-24. Al(2)O(3) promoted higher ME than HP-24 and control. SEM images revealed partial dissolution of the resin matrix in all treated groups. The smooth posts had higher BS and FS than serrated posts (p<0.05). Mechanical properties of the glass fiber posts and the bond strength between posts and composite material were not altered by the surface treatments, except for airborne-particle abrasion that increased the post elastic modulus.

The History of Growth Hormone Treatment for GHD in Japan.

2017-03-01

In Japan, treatment of growth hormone deficiency with pituitary-extracted human growth hormone (phGH) was covered by health insurance for the first time in 1975. However, because of the shortage of phGH, the Foundation for Growth Science (FGS) was founded in 1977 to control the use of the product by its registration system and to collect pituitary glands in Japan. In 1986, recombinant human growth hormone was first approved.

Purpose To explore the potential factors impacting the efficacy of venlafaxine extended release (ER) and treatment differences between 75 mg/day and 75–225 mg/day dose in patients with major depressive disorder (MDD). Methods We performed exploratory post hoc subgroup analyses of a randomized, double-blind, placebo-controlled study conducted in Japan. A total of 538 outpatients aged 20 years or older with a primary diagnosis of MDD who experienced single or recurrent episodes were randomized into three groups: fixed-dose, flexible-dose, or placebo. Venlafaxine ER was initiated at 37.5 mg/day and titrated to 75 mg/day for both fixed-dose and flexible-dose group, and to 225 mg/day for flexible-dose group (if well tolerated). Efficacy endpoints were changes from baseline at Week 8 using the Hamilton Rating Scale for Depression–17 items (HAM-D17) total score, Hamilton Rating Scale for Depression–6 items score, and Montgomery–Asberg Depression Rating Scale total score. The following factors were considered in the subgroup analyses: sex, age, HAM-D17 total score at baseline, duration of MDD, duration of current depressive episode, history of previous depressive episodes, history of previous medications for MDD, and CYP2D6 phenotype. For each subgroup, an analysis of covariance model was fitted and the adjusted mean of the treatment effect and corresponding 95% CI were computed. Due to the exploratory nature of the investigation, no statistical hypothesis testing was used. Results Venlafaxine ER improved symptoms of MDD compared with placebo in most subgroups. The subgroup with a long duration of MDD (>22 months) consistently showed greater treatment benefits in the flexible-dose group than in the fixed-dose group. Conclusion These results suggest that a greater treatment response to venlafaxine ER (up to 225 mg/day) can be seen in patients with a longer duration of MDD. Further investigations are needed to identify additional factors impacting the efficacy of

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.

Objectives The nationwide impact of antimicrobial-resistant infections on healthcare facilities throughout Japan has yet to be examined. This study aimed to estimate the disease burden of methicillin-resistant Staphylococcus aureus (MRSA) infections in Japanese hospitals. Design Retrospective analysis of inpatients comparing outcomes between subjects with and without MRSA infection. Data source A nationwide administrative claims database. Setting 1133 acute care hospitals throughout Japan. Participants All surgical and non-surgical inpatients who were discharged between April 1, 2014 and March 31, 2015. Main outcome measures Disease burden was assessed using hospitalization costs, length of stay, and in-hospital mortality. Using a unique method of infection identification, we categorized patients into an anti-MRSA drug group and a control group based on anti-MRSA drug utilization. To estimate the burden of MRSA infections, we calculated the differences in outcome measures between these two groups. The estimates were extrapolated to all 1584 acute care hospitals in Japan that have adopted a prospective payment system. Results We categorized 93 838 patients into the anti-MRSA drug group and 2 181 827 patients into the control group. The mean hospitalization costs, length of stay, and in-hospital mortality of the anti-MRSA drug group were US$33 548, 75.7 days, and 22.9%, respectively; these values were 3.43, 2.95, and 3.66 times that of the control group, respectively. When extrapolated to the 1584 hospitals, the total incremental burden of MRSA was estimated to be US$2 billion (3.41% of total hospitalization costs), 4.34 million days (3.02% of total length of stay), and 14.3 thousand deaths (3.62% of total mortality). Conclusions This study quantified the approximate disease burden of MRSA infections in Japan. These findings can inform policymakers on the burden of antimicrobial-resistant infections and support the application of infection prevention programs. PMID

Hepatocellular carcinoma (HCC) is a common malignant disease of the liver in China and Japan. The purpose of this study was to compare the outcomes of HCC patients after hepatectomy between two regional medical centers in China and Japan. Data on HCC after hepatectomy were collected from January 2005 to December 2014 from Nagasaki University Hospital in Nagasaki, Japan and the Second Affiliated Hospital of Nanchang University in Nanchang, China. The patient and tumor characteristics, HCC etiology, and overall survival rates after hepatectomy were investigated. Two hundred patients in the Nagasaki group and 238 patients in the Nanchang group were diagnosed with HCC and underwent hepatectomy. The major underlying liver diseases were hepatitis C infection (32%, 64/200) and nonalcoholic steatohepatitis (NASH) (34.5%, 69/200) in the Nagasaki group, while in the Nanchang group, hepatitis B infection (79.4%, 189/238) was the dominant etiology. Large tumors (> 5 cm), the presence of a tumor capsule and a high alpha-fetoprotein value (≥ 400 U/L) were more frequently observed in the Nanchang group as compared with the Nagasaki group (p < 0.05). According to an outcome analysis, the Nanchang patients showed worse survival rates as compared with Nagasaki patients, particularly those with American Joint Committee on Cancer stages I and III due to the aggressive character of HCC in the Nanchang group. There are significant differences in the clinicopathologic features and outcomes of HCC patients from Japan and China. These differences may impact the eligibility for potentially curative therapy and the prognosis of patients with HCC. Copyright © 2016. Published by Elsevier Taiwan.

Idiopathic pulmonary fibrosis (IPF) is a chronic fibrotic lung disease with a median survival of 2-5 years and limited treatment options. In 2008, pirfenidone became the first drug to be approved for IPF treatment in Japan. The aim of this study was to assess the safety of pirfenidone for IPF treatment in a clinical setting. We conducted a safety-oriented post-marketing surveillance of all patients with IPF who were administered pirfenidone in the first year after its launch in Japan. This was a prospective, non-interventional, observational study. Case report forms were used to collect survey data, comprising adverse events, acute exacerbations, patient demographics, concomitant drug use, and concurrent treatment data. Of the 1371 patients available for safety evaluation, two-thirds had stage III-IV disease. The incidence of total adverse drug reactions (ADRs) was 64.6%. ADRs with an incidence of ≥3% were decreased appetite, photosensitivity reaction, nausea, abdominal discomfort, malaise, somnolence, and hepatic function abnormal. This safety profile was consistent with the findings in phase II and III trials in Japan. The discontinuation rates due to adverse events at 12 months for each disease stage were similar; however, discontinuation caused by disease progression increased with disease severity. Treatment with pirfenidone stabilized both vital capacity and subjective symptoms in most patients (70-80%) treated for at least 6 months. This post-marketing surveillance in Japan showed that pirfenidone was generally well tolerated in patients with IPF, including those with severe lung function impairment.

Geochemical Character of the Aono Volcanic Group in SW Japan Arc: Implications for Genetic Relationship between Slab Melting and EM Isotopic Signature

The SW Japan arc is characterized by active subduction of a relatively young (15-26 Ma) segment of the Philippine Sea plate, Shikoku basin, beneath the Eurasian plate and is known for the occurrence of adakites on the quaternary volcanic front. As adakite is typically generated in subduction zones, where high geothermal gradients can be attained in the slab, the adakite magmas are considered to be produced by slab melting. From this perspective, adakites are considered to be modern geochemical analogues of the tonalite-trondhjemite-granodiorite (TTG) suite that can be a major constituent of early continental crust. It has been inferred that recycling of continental crustal material back into the mantle could be a possible origin of enriched mantle reservoirs, such as EM1 and EM2. In order to reveal the role of slab melting on the production of EM isotopic signature, we have conducted a detailed major/trace element and Pb-Nd-Sr isotopic study of 17 adakites from Aono volcanic group in the western end of Honshu Island. The isotopic compositions of the Aono volcanic rocks clearly form a mixing line between the Shikoku back arc basin basalts and local sediments from the Nankai Trough. In addition, the isotopic compositions of Aono adakites have depleted isotopic composition showing some overlap with subducted Shikoku basin basalts. This may imply that the chemical composition of Aono adakites could be mainly derived from Shikoku basin basalts as pointed out by recent work (Kimura et al., 2014). Accordingly, the effect of crustal contamination or sediment melting could be relatively small. On the basis of this assumption, the chemical composition of Aono adakites are used to estimate the chemical fractionation during slab melting. In this presentation, we will present new results of isotopic and trace element analyses of adakites from Aono volcanic group in the SW Japan and discuss role of slab melting in the production of EM reservoirs.

In Japan, a dramatic rise in suicide rates was observed in the 1950s, especially among the younger population, and then the rate decreased rapidly again in the 1960s. The aim of this study was to assess secular trends in method-specific suicides by gender and age in Japan between 1950 and 1975. We paid special attention to suicides by poisoning (solid and liquid substances), and their contribution to dramatic swings in the overall suicide rate in Japan during the 1950s and 1960s. Mortality and population data were obtained from the Vital Statistics of Japan and Statistics Bureau, Ministry of Internal Affairs and Communications in Japan, respectively. We calculated method-specific age-standardized suicide rates by gender and age group (15-29, 30-49, or 50+ years). The change in the suicide rate during the research period was larger in males than females in all age groups, and was more marked among people aged 15-29 years compared to those aged 30-49 years and 50 years or over. Poisoning by solid and liquid substances overwhelmingly contributed to the dramatic change in the overall suicide rates in males and females aged 15-49 years in the 1950s and 1960s. For the peak years of the rise in poisoning suicides, bromide was the most frequently used substance. Our results for the 1950s and 1960s in Japan illustrated how assessing secular trends in method-specific suicides by gender and age could provide a deeper understanding of the dramatic swings in overall suicide rate. Although rapid increases or decreases in suicide rates have been also observed in some countries or regions recently, trends in method-specific suicides have not been analyzed because of a lack of data on method-specific suicide in many countries. Our study illustrates how the collection and analysis of method-specific data can contribute to an understanding of dramatic shifts in national suicide rates.

Background To elucidate relationships between disaster damage conditions and sleep duration among children who survived the 2011 Japan earthquake and tsunami. Methods The subjects comprised 12,524 children in kindergartens, elementary schools, and junior high schools in Ishinomaki City, Miyagi Prefecture, Japan. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a sleep questionnaire were distributed to them. A questionnaire regarding disaster damage conditions of the children’s homes was distributed to their teachers. Of 12,524, an effective response was obtained from 11,692 (93.3%). Results Relationships between sleep duration and traumatic symptoms were displayed low correlations. Children with house damage and/or evacuation experiences slept for a significantly shorter time than children without these experiences. Conclusion It is critical not only to examine traumatic symptoms in children but also to collect sleep duration and disaster damage conditions following natural disasters. PMID:23738015

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.

Expressions of Identity and Self in Daily Life at a Group Home for Older Persons With Dementia in Japan.

This study focuses on expressions of identity and self among residents at a group home for older persons with dementia in Japan--a study, which started as an explorative study on spirituality--and how residents make meaning of life. Although aware of stages of dementia illness and briefly commenting on these, the analysis does not make any specific point of it. This article views dementia from a sociocultural perspective and is based on participant observations at a group home with 19 residents, combined with interviews with 6 of them. Two central concepts for the study are discussed and drawn on in the analysis: ie, meaning home and family, and dementia and boke, senility. The study examines how the group home is ie and concludes that it is "home enough" in the sense that one's identity and self are honored here. The old word boke represents a state in which one has "given up" any attempts to keep one's mental health. This concept was used by some residents to mark the line between those who were "helpless" with boke and those who could manage by themselves without boke. Identities are analyzed in different terms: as profession, as feeling secure, as being physically close, in social interactions, and as being cared for properly also after death. The analysis of self and identity showed that contentment in life was expressed in various ways, as a whole or as a patchwork with light and dark colors, and that it is still in process. Here, the supportive but discreet scaffolding of staff seems to matter. Life is lived until death, and the farewell ceremonies are analyzed as existential closures for many--and for life finalized here at Ie, the group home.

In the Tokai No. 2 power plant of the Japan Atomic Power Company, about 80% of the annual dose equivalent is received during periodic maintenance outages. A project group for dose reduction was organized at the company`s headquarters in 1986; in 1988, they proposed a five-year program to reduce by half the collective dose of 4 person-Sv per normal outage work. To achieve the target dose value, some dose-reduction measures were undertaken, namely, permanent radiation shielding, decontamination, automatic, operating machines, and ALARA organization. As the result, the collective dose from normal outage work was 1.6 person-Sv in 1992, which wasmore » less than the initial target value.« less

In Japan, influenza like epidemics were described many times since Heian era. However, Spanish flu as the modern medicine invaded Japan in 1918, thus almost infected 390,000 patients died with associated pneumonia. After the discovery of influenza virus in 1933, Japan experienced pandemic influenza--Asian flu(H2N2) in 1957. After about 10 years, Hong Kong flu (H3N2) came to Japan at 1968. However, we had many reliable antibiotics but had not any antiviral drug at the early time. After year 2000, we fortunately obtained reliable three antiviral drugs such as amantadine, oseltamivir and zanamivir. Moreover, very useful rapid test kits for influenza A and B viruses were developed and used in Japan. 2009 H1N1 influenza epidemic occured in Japan after the great epidemic in Mexico and North America but elderly patient was few. With together, host conditions regarding with high risk are changing. Lessons from past several pandemic influenza are those that many issues for changing high risk conditions, viral genetic changes, developing antiviral agents, developing new useful vaccins and determinating bacterial secondary pathogens are important.

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.

Osteoporosis, osteoporosis-related fractures, and diabetes are considerable health burdens in Japan. Diabetes in patients with osteoporosis has been reported to be associated with increased fracture risk. This retrospective analysis of a Japanese hospital claims database investigated the real-world effect of type 2 diabetes mellitus (T2DM) on the incidence of clinical fractures, costs, and healthcare resource utilization in patients with osteoporosis and a subgroup of patients prescribed raloxifene. Women aged ≥50 years diagnosed with osteoporosis who had a first prescription claim for osteoporosis treatment with a pre-index period ≥12 months and a post-index period of 30 months were selected from a database extract (April 2008-July 2013). Patients prescribed raloxifene were classed as a subgroup. Patients diagnosed with T2DM constituted the T2DM group; all other patients (excluding patients with type 1 diabetes mellitus) constituted the non-diabetes mellitus (non-DM) group. Groups were matched by exact matching, using selected baseline characteristics. Patient demographic and clinical characteristics were compared using chi-squared tests, t-tests, or Wilcoxon rank sum tests. Time to first fracture was examined using Kaplan-Meier survival analysis. Overall, the T2DM and non-DM groups had 7580 and 7979 patients, respectively; following matching, there were 3273 patients per group. In the raloxifene subgroup, the T2DM and non-DM groups had 668 and 699 patients, respectively; following matching, there were 239 patients per group. At baseline, the T2DM group (overall and raloxifene subgroup) had significantly higher healthcare resource utilization and comorbidities. During the post-index period, a similar pattern was observed in the overall group, even after matching; the T2DM group also had a higher incidence of fracture. In the raloxifene subgroup, after matching, there were no significant differences in fracture incidence or costs and fewer differences in

The Gender Equality Promotion Committee of the Physical Society of Japan (JPS) was established as a result of the First International IUPAP Conference on Women in Physics (Paris, 2002). It is a gender-balanced team of 12 full members and a group of net-commentators. The former chairperson of the committee, Masako Bando, was selected to be the president of JPS between September 2006 and August 2007. Based on the survey on the present status of the gender equality and the research environment of the JPS members in 2001, JPS advanced two recommendations to the governmental authorities, academic institutes, and organizations: for flexible childcare supports and for improved research granting systems for post-doctoral fellows and part-time researchers in August 2003. Now these activities have become nationwide with the establishment in October 2002 of the Japan Inter-Society Liaison Association Committee for Promoting Equal Participation of Men and Women in Science and Engineering (EPMEWSE). It has 44 member societies, including 19 observers, from various academic fields. An extended survey was carried out by EPMEWSE in November 2003; 20,000 respondents revealed diverse visions of scientists and engineers. These activities effectively help foster public understanding and awareness of the state of women in physics, especially among policy-making authorities. In 2005 the Cabinet is drawing up two Basic Plans for 2006-2010: the Science and Technology Basic Plan for the third term and the Basic Plan for the Gender-Equal Society for the second term. To attract girls into science and engineering, JPS is organizing the Girls Science Summer School to be held in August 2005 in collaboration with the National Women Education Center and EPMEWSE.

In the consumer electronics industry, precision processing technology is the basis for enhancing product functions and for minimizing components and end products. Throughout Japan, manufacturing technology is seen as critical to the production and assembly of advanced products. While its population has increased less than 30 percent over twenty-five years, Japan's gross national product has increase thirtyfold; this growth has resulted in large part from rapid replacement of manual operations with innovative, high-speed, large-scale, continuously running, complex machines that process a growing number of miniaturized components. The JTEC panel found that introduction of next-generation electronics products in Japan goes hand-in-hand with introduction of new and improved production equipment. In the panel's judgment, Japan's advanced process technologies and equipment development and its highly automated factories are crucial elements of its domination of the consumer electronics marketplace - and Japan's expertise in manufacturing consumer electronics products gives it potentially unapproachable process expertise in all electronics markets.

To evaluate the formal debate as an active learning strategy within a postgraduate specialty track education programme in periodontics. A formal debate was implemented as an active learning strategy in the programme. The participants were full-time faculty, residents and dentists attending special courses at a teaching hospital in Japan. They were grouped into two evenly matched opposing teams, judges and audience. As a preparation for the debate, the participants attended a lecture on critical thinking. At the time of debate, each team provided a theme report with a list of references. Performances and contents of the debate were evaluated by the course instructors and audience. Pre- and post-debate testing was used to assess the participants' objective knowledge on clinical periodontology. Evaluation of the debate by the participants revealed that scores for criteria, such as presentation performance, response with logic and rebuttal effectiveness were relatively low. Thirty-eight per cent of the participants demonstrated higher test scores after the debate, although there was no statistically significant difference in the mean scores between pre- and post-tests. At the end of the debate, vast majority of participants recognised the significance and importance of the formal debate in the programme. It was suggested that the incorporation of the formal debate could serve as an educational tool for the postgraduate specialty track programme. © 2011 John Wiley & Sons A/S.

Mortality subsequent to a hospitalisation for heart failure is reported to be much lower in Japan than in the United Kingdom (UK). This could reflect differences in disease severity or in management. Accordingly, we directly compared patient backgrounds and outcomes between Japan and UK. Consecutive patients admitted to academic hospitals in the UK and Japan with heart failure had a common set of variables, including plasma concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP), collected during admission. Mortality during hospitalisations, at 90 and 180 days was recorded and stratified by quintile of NT-proBNP. Overall, 935 patients were enrolled; 197 from UK and 738 from Japan. Median (interquartile range) age [UK: 78 (71-88) vs. Japan: 78 (70-84) years; p = 0.947], glomerular filtration rate [UK: 49 (34-68) vs. Japan: 49 (33-65) ml/min/1.73 m 2 ; p = 0.209] and plasma NT-proBNP [UK: 4957 (2278-10,977) vs. Japan: 4155 (1972-9623) ng/l; p = 0.186] were similar, but systolic blood pressure was lower in the UK [118 (105-131) vs. 137 (118-159) mmHg; p < 0.001]. Patients with a higher plasma NT-proBNP had a worse prognosis in both countries; in-hospital and post-discharge mortality rates were higher in the UK even after adjusting for prognostic variables including NT-proBNP. This analysis suggests that either unobserved differences in patient characteristics or differences in care (formal or informal) rather than greater heart failure severity may account for the worse outcome of heart failure in the UK compared to Japan.

We performed a safety evaluation using the procedure devised by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) of the following four flavouring substances that belong to the class of 'aliphatic primary alcohols, aldehydes, carboxylic acids, acetals, and esters containing additional oxygenated functional groups' and are uniquely used in Japan: butyl butyrylacetate, ethyl 2-hydroxy-4-methylpentanoate, 3-hydroxyhexanoic acid and methyl hydroxyacetate. Although no genotoxicity study data were found in the published literature, none of the four substances had chemical structural alerts predicting genotoxicity. All four substances were categorised as class I by using Cramer's classification. The estimated daily intake of each of the four substances was determined to be 0.007-2.9 μg/person/day by using the maximised survey-derived intake method and based on the annual production data in Japan in 2001, 2005 and 2010, and was determined to be 0.250-600.0 μg/person/day by using the single-portion exposure technique and based on average-use levels in standard portion sizes of flavoured foods. Both of these estimated daily intake ranges were below the threshold of toxicological concern for class I substances, which is 1800 μg/person/day. Although no information from in vitro and in vivo toxicity studies for the four substances was available, these substances were judged to raise no safety concerns at the current levels of intake.

Carbon dioxide embodied flow in international trade has become an important factor in defining global carbon emission responsibility and climate policy. We conducted an empirical analysis for China and Japan for the years 2000-2014, using a multi-region input-output model and considering the rest of the world as a comparison group. We compared the two countries' direct and complete carbon dioxide emissions intensity and bilateral economic activities such as imports and exports, production and consumption to analyze the difference between China and Japan. The results showed that the intensities of carbon emissions in all sectors of China were higher than that in Japan and that China's annual production-based emissions were greater than consumption-based emissions, the opposite of these relationships in Japan. China was a typical net carbon export country, and carbon embodied in its imports and exports continued to increase throughout the study period. In contrast, Japan's volume and growth rate of embodied carbon emissions were far less than China's and Japan was a typical net carbon import country. Finally, the conclusions of this study support recommendations for the formulation of international carbon emission responsibility allocation, domestic abatement policy as well as China's trade policy.

The Tohoku-oki earthquake in 2011 revealed that an M9-class giant earthquake could occur even in the old subduction zone and that coseismic slip can reach its frontal wedge, where we considered no significant stress had been accumulated in. One of the leading figure of such finding is in situ seafloor geodetic measurement, such as GPS/A technique for horizontal displacement and pressure gauge for vertical displacement. Japan Coast Guard and Japanese university group had developed several GPS/A sites near the source region of the Tohoku-oki earthquake and detected quite large coseismic movements over 20 m in there. Displacement vectors observed these sites showed systematic variation, i.e., mainly confined in the off-Miyagi area and getting larger near the trench. However, subsequent post-seismic deformation shows inexplicable distribution. In order to elucidate this complex feature, MEXT Japan has decided to construct dense and widely-extended GPS/A network along Japan trench, including deep area (~6000m). We, Tohoku and Nagoya universities, have firstly developed high-powered seafloor transponders with an omnidirectional acoustic unit that works at 6000 m deep ocean and enable acoustic ranging over 13 km slant length. In addition, using high-energy density battery, its lifetime is expected 10 years with normal operation. Secondly, we examined the optimal distribution of GPS/A sites forming a network, taken pre-existing sites into consideration. The new network consists of 20 sites (roughly four transponders at a single site and 86 transponders in total). The distribution is dense near the area of complex post-seismic deformation and extended over 400 km to cover the adjacent area of the source region, in where induced earthquake may be expected. The largest obstacle to draw network plan is seafloor topography. Because a GPS/A site is a seafloor benchmark, its installation must be on flat and locally stable spot. Since a single GPS/A site consists of three or more

The 2011 Tohoku-Oki earthquake ruptured roughly 200 km wide and 500 km long megathrust along the Japan Trench. The rupture propagated to the trench axis with a maximum slip about 50 m near the trench axis. As a consequence of this large near-trench slip, earthquakes have been activated near the axis of the Japan Trench off Miyagi, northeast Japan. We have conducted ocean bottom seismograph (OBS) experiments in the Japan Trench axis area, surrounding area of the IODP JFAST drilling site, since the occurrence of the 2011 Tohoku-Oki earthquake. Although conventionally used OBS cannot be deployed at seafloor deeper than 6000 m water depth, we used newly developed ultra-deep OBS using ceramic sphere, which can be deployed at a depth of 9000 m, for the observations in the trench axis. The ultra-deep OBS has almost equivalent dimensions and weight with the conventionally used OBS, thus we can handle it in the same manner with the conventionally OBS without any special operation. As a result of a series of the OBS observations, we obtained accurate hypocenter locations and focal mechanisms in both seaward and landward of the trench axis. Earthquakes near the trench axis area were located within the overriding and incoming/subducting plates with very few on the plate interface below the inner trench slope landward of the trench axis. Most of the earthquakes both in the overriding and incoming/subducting plates having normal or strike-slip faulting focal mechanisms with T-axis normal to the trench axis. This indicates that tensional stress is dominant in the trench axis area. However, most seaward part of the seismicity within the overriding plate is characterized by a localized cluster of trench-normal compressional earthquakes, which may relate to spatial variation of the frictional behavior of the shallowest part of the megathrust. On the other hand, trench-normal extensional earthquakes in the incoming/subducting Pacific plate were located at depths shallower than about

A backarc inner rift is formed after a major opening of backarc basin near a volcanic front away from the spreading center of a major backarc basin. An obvious example is the inner rift along the Izu-Bonin arc. Similar inner rift zones have been developed along the Sea of Japan coast of Honshu island, Japan. NE and SW Japan arcs experienced strong shortening after the Miocene backarc rifting. The amount of shortening shows its maximum along the backarc inner rifts, forming a fold-and-thrust of thick post-rift sediments over all the structure of backarc. The rift structure has been investigated by onshore-offshore deep seismic reflection/wide-angle reflection surveys. We got continuous onshore-offshore image using ocean bottom cable and collected offshore seismic reflection data using two ships to obtain large offset data in the difficult area for towing a long streamer cable. The velocity structure beneath the rift basin was deduced by refraction tomography in the upper curst and earthquake tomography in the deeper part. It demonstrates larger P-wave velocity in upper mantle and lower crust, suggesting a large amount of mafic intrusion and thinning of upper continental crust. The deeper seismicity in the lower crust beneath the rift basin accords well to the mafic intrusive rocks. Syn-rift volcanism was bimodal, comprising a reflective unit of mafic rocks around the rift axis and a non-reflective unit of felsic rocks near the margins of the basins. Once rifting ended, thermal subsidence, and subsequently, mechanical subsidence related to the onset of the compressional regime, allowed deposition of up to 5 km of post-rift, deep marine to fluvial sedimentation. Continued compression produced fault-related folds in the post-rift sediments, characterized by thin-skin style of deformation. The syn-rift mafic intrusion in the crust forms convex shape and the boundary between pre-rift crust and mafic intrusive shows outward dipping surface. Due to the post rift

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 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

Coronary heart disease incidence and mortality remain very low in Japan despite major dietary changes and increases in risk factors that should have resulted in a substantial increase in coronary heart disease rates (Japanese paradox). Primary genetic effects are unlikely, given the substantial increase in coronary heart disease in Japanese migrating to the United States. For men aged 40-49 years, levels of total cholesterol and blood pressure have been similar in Japan and the United States throughout their lifetimes. The authors tested the hypothesis that levels of subclinical atherosclerosis, coronary artery calcification, and intima-media thickness of the carotid artery in men aged 40-49 years are similar in Japan and the United States. They conducted a population-based study of 493 randomly selected men: 250 in Kusatsu City, Shiga, Japan, and 243 White men in Allegheny County, Pennsylvania, in 2002-2005. Compared with the Whites, the Japanese had a less favorable profile regarding many risk factors. The prevalence ratio for the presence of a coronary calcium score of > or =10 for the Japanese compared with the Whites was 0.52 (95% confidence interval: 0.35, 0.76). Mean intima-media thickness was significantly lower in the Japanese (0.616 mm (standard error, 0.005) vs. 0.672 (standard error, 0.005) mm, p < 0.01). Both associations remained significant after adjusting for risk factors. The findings warrant further investigations.

Studies examining workers' diet according to smaller occupational groups within "large occupational categories" are sparse. The aim of this study was to examine the potential differences in workers' diets based on the classification of workers into smaller occupational groups that comprise "large occupational categories". The subjects of this study were working fathers who had participated in the Japan Environment and Children's Study (N = 38,656). Energy and nutrient intake were calculated based on data collected from the Food Frequency Questionnaire. Occupations were classified according to the Japanese Standard Occupational Classification. Logistic regression analyses were performed to examine the adherence to current dietary recommendations within smaller occupational groups. In particular, significant differences were observed among the categorical groups of "professional and engineering workers", "service workers", and "agricultural, forestry, and fishery workers". In "professional and engineering workers", teachers showed higher odds of adherence to calcium intake recommendations compared with nurses (OR, 2.54; 95% CI, 2.02⁻3.14; p < 0.001). In "agricultural, forestry, and fishery workers", agriculture workers showed higher odds of adherence to calcium (OR, 2.15; 95% CI, 1.46⁻3.15; p < 0.001) and vitamin C (OR 1.90, 95% CI 1.31⁻2.74, p = 0.001) intake recommendations compared with forestry and fishery workers. These findings may be beneficial from a research perspective as well as in the development of more effective techniques to improve workers' diet and health.

Although a household questionnaire survey is important for estimating vaccination coverage, it raises several problematic issues. A household survey was conducted on 900 subjects aged 2, 4, and 6 years living in Obu City, Japan, and a second survey for non-respondents to the first survey was then conducted. Questionnaires bearing a subject's name were used for half of the subjects, while the others were anonymous (the named and nameless groups, respectively). The vaccination dates of six kinds of vaccines, including poliovirus and measles vaccine, for those in the named group were reviewed using the administrative records at the Obu City Health Center. The response rate was 70.1% in the first survey and 84.1% in the first and second surveys combined. The response rate for both groups was nearly equal. Based on administrative records in the named group, the vaccination coverage in the respondents was 0.9-2.9% higher than that in total subjects, and that in the respondents to the first survey was 0.8-4.9% higher. There were very few inconsistencies in the vaccination status between responses to the questionnaire and data of administrative records among respondents in the named group. These results suggested that vaccination coverage from a household questionnaire survey in Japan might not be extremely biased by either non-responses or incorrect answers.

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

PubMed

Maeda, Hideki; Kurokawa, Tatsuo

2015-12-01

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.

The JTEC Panel on Advanced Composites surveyed the status and future directions of Japanese high-performance ceramic and carbon fibers and their composites in metal, intermetallic, ceramic, and carbon matrices. 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.

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.

This study investigated: (i) changes in the incidence of acute otitis media (AOM) following introduction of public funding for free inoculation with 7- and 13-valent pneumococcal conjugate vaccines (PCV7 and PCV13, respectively) and (ii) changes in the rate of myringotomies for AOM (MyfA) in children 1year following the publication of the first edition of the clinical practice guidelines for the diagnosis and management of AOM in children in Japan. PCV7 was launched on the Japanese market in 2010 and gained public funding in 2011. PCV7 was replaced with PCV13 in November 2013. Using the Japan Medical Data Center Claims Database, an 11-year study conducted between January 2005 and December 2015 investigated the decline in the incidence of visits to medical institutions (VtMI) due to all-cause AOM in children <15years. The rate of MyfA from January 2007 to December 2015was also investigated and changes before and after introduction of public funding for PCV7 (pfPCV7) and PCV13 (pfPCV13) for children were examined. Statistical data for the age group between 10 years and <15years served as the control. An analysis was conducted to examine changes for each age group, from infants that had received PCVs to children <5years. Statistical analysis was performed using the chi-square test and Ryan's multiple comparison tests. Ryan's multiple comparison tests were applied at a 5% level of significance. Due to significant changes in the guidelines on the indications for myringotomy introduced in 2013, statistical analysis of the rate of MyfA was limited to the pre- and post-PCV7 period. After introduction of pfPCV7 and pfPCV13, no significant suppression of the incidence of VtMI was observed in any age group. There was a gradual decline in the rate of MyfA after 2011. Compared to the control group, significant differences in all age groups from infants to children <5years were observed (p<0.009, chi-square test). Within 2 years after the introduction of PCV7, a significant

To design a program targeting recovery of self-esteem in patients with mental disorders, and to clarify the changes after the program to determine its effectiveness. This study employed a one group pre- and post design, which comprised baseline, post-intervention, and 3 month follow-up phases, and recruited 41 Japanese patients with mental disorders living in the community. The authors administered the nurse-led group cognitive-behavioral therapy program for the recovery of self-esteem, which comprised 12 sessions, to the participants. The follow-up investigations were conducted immediately and 3 months after the program. The present authors used the Rosenberg Self-Esteem Scale (RSES), Profile of Mood States (POMS), Subjective Well-Being Inventory (SUBI), and Test to Determine the Characteristics of Ideas as subjective measures and the Brief Psychiatric Rating Scale (BPRS) as an objective measure. After controlling for the factors of medication and use of social services, improvement was observed in all measures of evaluation. The authors identified improvement at post-intervention and follow up. The scores for the RSES, BPRS, confidence in coping, and inadequate mental mastery at post-intervention and follow up were significantly higher than those at baseline, and these beneficial effects were maintained 3 months after the program. The program may aid in recovering and maintaining self-esteem of patients suffering from mental disorders. However, it is necessary to conduct a randomized controlled clinical trial to confirm these findings. © 2016 Japan Academy of Nursing Science.

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.

National medical projects are carried out according to medical care plans directed by the Medical Care Act of Japan. In order to improve Japanese perinatal medical care, it is necessary to determine the factors that might influence perinatal outcome. Statistical data of births and perinatal deaths were obtained for all municipalities in Japan from 2008 to 2012 from the Portal Site of Official Statistics of Japan (e-Stat). The perinatal mortality of all 349 Japanese secondary medical care zones was calculated. The number of neonatal intensive care units (NICUs), maternal-fetal intensive care units (MFICUs), pediatricians and obstetricians in 2011 were also obtained from e-Stat. Nine secondary medical care zones in two prefectures, Fukushima (7) and Miyagi (2) were excluded to eliminate the influence of the 2011 Great East Japan Earthquake. The 340 secondary medical care zones were divided into three groups according to population size and density: metropolis, provincial city, and depopulation. The number of secondary medical care zones in each group were 52, 168, and 120, respectively. The secondary medical care zones in the depopulation group had fewer pediatricians and significantly fewer NICUs and MFICUs than the metropolis group, but there was no significant difference in perinatal mortality. The only independent risk factor for high perinatal mortality, determined by multivariable analysis, was the absence of an NICU (P = 0.011). To consider directions in perinatal medical care, planned arrangement and appropriate access to NICUs is indispensable. © 2016 Japan Society of Obstetrics and Gynecology.

There were no differences between Canada and Japan in the prevalence and symptoms of sleep paralysis (SP), but many more Canadians considered SP to be a dream. The difference was considered to be derived from the fact that there is a common expression for SP in Japan but there is not one in Canada. Then, we investigated why there are individuals who consider SP to be a dream and others who do not, and found that many Japanese who regarded it as a dream did not report the symptom of 'unable to move', while in Canada, self-evaluation of spirituality was different between the two groups.

The Japan Medical Association's disaster preparedness: lessons from the Great East Japan Earthquake and Tsunami.

Ishii, Masami; Nagata, Takashi

2013-10-01

A complex disaster, the Great East Japan Earthquake of March 11, 2011, consisted of a large-scale earthquake, tsunami, and nuclear accident, resulting in more than 15 000 fatalities, injuries, and missing persons and damage over a 500-km area. The entire Japanese public was profoundly affected by "3/11." The risk of radiation exposure initially delayed the medical response, prolonging the recovery efforts. Japan's representative medical organization, the Japan Medical Association (JMA), began dispatching Japan Medical Association Teams (JMATs) to affected areas beginning March 15, 2011. About 1400 JMATs comprising nearly 5500 health workers were launched. The JMA coordinated JMAT operations and cooperated in conducting postmortem examination, transporting large quantities of medical supplies, and establishing a multiorganizational council to provide health assistance to disaster survivors. Importantly, these response efforts contributed to the complete recovery of the health care system in affected areas within 3 months, and by July 15, 2011, JMATs were withdrawn. Subsequently, JMATs II have been providing long-term continuing medical support to disaster-affected areas. However, Japan is at great risk for future natural disasters because of its Pacific Rim location. Also, its rapidly aging population, uneven distribution of and shortage of medical resources in regional communities, and an overburdened public health insurance system highlight the need for a highly prepared and effective disaster response system.

2017-06-01

On 11 March 2011, the Great East Japan Earthquake, followed by a tsunami and nuclear-reactor meltdowns, produced one of the most severe disasters in the history of Japan. The adverse impact of this 'triple disaster' on the health of local populations and the health system was substantial. In this study we examine population-level health indicator changes that accompanied the disaster, and discuss options for re-designing Fukushima's health system, and by extension that of Japan, to enhance its responsiveness and resilience to current and future shocks. We used country-level (Japan-average) or prefecture-level data (2005-2014) available from the portal site of Official Statistics of Japan for Fukushima, Miyagi, and Iwate, the prefectures that were most affected by the disaster, to compare trends before (2005-2010) and after (2011-2014) the 'disaster'. We made time-trend line plots to describe changes over time in age-adjusted cause-specific mortality rates in each prefecture. All three prefectures, and in particular Fukushima, had lower socio-economic indicators, an older population, lower productivity and gross domestic product per capita, and less higher-level industry than the Japan average. All three prefectures were 'medically underserved', with fewer physicians, nurses, ambulance calls and clinics per 100 000 residents than the Japan average. Even before the disaster, age-adjusted all-cause mortality in Fukushima was in general higher than the national rates. After the triple disaster we found that the mortality rate due to myocardial infarction increased substantially in Fukushima while it decreased nationwide. Compared to Japan average, spikes in mortality due to lung disease (all three prefectures), stroke (Iwate and Miyagi), and all-cause mortality (Miyagi and Fukushima) were also observed post-disaster. The cause-specific mortality rate from cancer followed similar trends in all three prefectures to those in Japan as a whole. Although we found a sharp

Japan has been one of the most successful countries in the world in the realm of terrestrial robot applications. The panel found that Japan has in place a broad base of robotics research and development, ranging from components to working systems for manufacturing, construction, and human service industries. From this base, Japan looks to the use of robotics in space applications and has funded work in space robotics since the mid-1980's. The Japanese are focusing on a clear image of what they hope to achieve through three objectives for the 1990's: developing long-reach manipulation for tending experiments on Space Station Freedom, capturing satellites using a free-flying manipulator, and surveying part of the moon with a mobile robot. This focus and a sound robotics infrastructure is enabling the young Japanese space program to develop relevant systems for extraterrestrial robotics applications.

Implementation process and challenges for the community-based integrated care system in Japan

Tsutsui, Takako

2014-01-01

Background Since 10 years ago, Japan has been creating a long-term vision to face its peak in the number of older people that will be reached in 2025 when baby boomers will turn 75 years of age. In 2003, the government set up a study group called “Caring for older people in 2015” which led to a first reform of the Long-Term Care Insurance System in 2006. This study group was the first to suggest the creation of a community-based integrated care system. Reforms Three measures were taken in 2006: ‘Building an active ageing society: implementation of preventive care services’, ‘Improve sustainability: revision of the remuneration of facilities providing care’ and ‘Integration: establishment of a new service system’. These reforms are at the core of the community-based integrated care system. Discussion The socialization of long-term care that came along with the ageing of the population, and the second shift in Japan towards an increased reliance on the community can provide useful information for other ageing societies. As a super ageing society, the attempts from Japan to develop a rather unique system based on the widely spread concept of integrated care should also become an increasing focus of attention.

The Japan Adult Leukemia Study Group (JALSG) AML201 protocols are regimens for remission induction and consolidation chemotherapy of acute myeloid leukemia (AML) and have been widely accepted in Japan since 2001. Management of infectious complications during chemotherapy has a key role in the supportive care of AML patients. By using case report forms collected in December 2001 and December 2005, we retrospectively analyzed the infectious complications in adult patients treated by using the JALSG AML201 protocols against AML (excluding promyelocytic leukemia). Of 980 patients, 80.2% experienced febrile neutropenia (FN), 8.3% bacteremia/fungemia, and 10.3% pulmonary infection at least once during remission-induction chemotherapy. Gram-positive bacteremia accounted for 65.1% of bacteremia/fungemia in 2001-2005, compared with 38.2% in 1987-1991 and 45.9% in 1992-1995. Of 750 patients, 81.9% experienced FN, 21.9% bacteremia/fungemia, and 9.1% pulmonary infection at least once during consolidation chemotherapy. During consolidation chemotherapy, bacteremia/fungemia and pulmonary infection were significantly more frequent in the high-dose cytarabine (HDAC) arm than in the conventional multiagent arm (25.9 vs. 17.9% and 12.7 vs. 7.7%, respectively). Invasive pulmonary aspergillosis accounted for 15.8% of pulmonary infections during remission induction and 19.7% during consolidation chemotherapy. Our data suggest that patterns of infectious complications have changed between 1987 and 2005, possibly because of chemoprophylaxis with oral fluoroquinolones and improved diagnosis of invasive pulmonary aspergillosis by serum antigen analysis.

Data from 69,525 animals were used to compare two types of analyses, one of them having the weaning management group (WEMANG) included as an effect in the contemporary group (F_WEMANG) and the other considering the weaning management group as a random effect, not related to the mathematical model (R_WEMANG) for post-weaning traits. The components of (co)variance were estimated for pre-weaning traits (birth weight and weaning weight) and for post-weaning traits [scrotal circumference (SC), weight gain from weaning to 18 months of age (WG) and muscle score (MUSC)] in Nellore cattle, based on a complete animal model. Heritability of SC, WG and MUSC for the F_WEMANG model was equal to 0.46 ± 0.02, 0.38 ± 0.03 and 0.26 ± 0.01, and for the R_WEMANG model it was 0.45 ± 0.02, 0.31 ± 0.03 and 0.25 ± 0.01, respectively. Genetic correlations between all the studied traits varied between 0.07 ± 0.01 and 0.77 ± 0.03 in F_WEMANG and between 0.02 ± 0.01 and 0.76 ± 0.04 in R_WEMANG. The R_ WEMANG model allowed a decrease in the number of contemporary groups as well as an increase in the number of observations per group without significant alterations in heritability coefficients, for the post-weaning traits. Consequently, the analysis became more robust and avoided having contemporary groups with low variability.

The organ donation rate in Japan is much lower than that in other developed countries for several reasons. An advanced educational program for in-hospital procurement coordinators is a possible solution for this. We introduced a Transplant Procurement Management (TPM) educational program at Hyogo Prefecture, Japan. Ten healthcare professionals at Hyogo Prefecture participated in the Advanced International TPM course to educate themselves on TPM and held 2 TPM Model Organ Procurement Training Workshops at Hyogo Prefecture for in-hospital procurement coordinators. Furthermore, we held 2 workshops outside Hyogo Prefecture and at the same time undertook a pre-workshop questionnaire survey to evaluate the ability and motivation with respect to organ donation. To evaluate the effectiveness of the workshops, we conducted post-workshop and 3-months-after workshop questionnaire surveys. The results of the pre-workshop survey revealed that in-hospital procurement coordinators lacked the knowledge regarding the entire organ donation process, the current status of organ donation in Japan, and the definition of brain death. Moreover, they did not completely understand the meaning of "organ donation." The results of the post-workshop questionnaire survey showed that the educational program was effective to improve the knowledge and skills of organ donation and motivated behavioral changes among the participants. The survey results showed that our TPM model educational program offered sufficient knowledge and skills to increase organ donation at Hyogo Prefecture. We will continue this program and make an effort to further contribute to the Japanese organ donation activities. Copyright © 2016 Elsevier Inc. All rights reserved.

Cooperation between civilian and military forces, including the Japan Self-Defense Force (JSDF), enabled wide-ranging disaster relief after the Great East Japan Earthquake. Nevertheless, many preventable fatalities occurred, particularly related to an inability to treat chronic disease, indicating the need to plan for the provision of long-term medical aid after natural disasters in stricken areas and evacuation shelters. To assist in this effort, this report (1) provides an overview of the consequences of the medical response to the Great East Japan Earthquake, the largest natural disaster ever to hit Japan, focusing on the role and actions of the JSDF; (2) discusses the lessons learned regarding the provision of medical aid and management by the JSDF after this disaster, looking at the special challenges of meeting the needs of a rapidly aging population in a disaster situation; and (3) provides recommendations for the development of strategies for the long-term medical aid and support after natural disasters, especially with regard to the demographics of the Japanese population.

Promoting health during the American occupation of Japan the public health section, Kyoto Military Government Team, 1945-1949.

Nishimura, Sey

2008-03-01

During the American occupation of Japan (1945-1952), young public health officers from the US Army Medical Corps were posted in local US Army military government teams. These young doctors (aged 25 to 27 years), who had not absorbed the strong anti-Japanese tradition of the US military during World War II, seem to have alleviated the initial resentment felt by the Japanese toward the new governors of their homeland. The case of the Kyoto Military Government Team illustrates the Kyoto citizenry's positive view of some American-directed public health measures. The team's services helped to counter widely held negative views on colonialism, occupation, and public health; lessened resentment toward the unilateral command structure of the occupation forces; and contributed to improved relations between the United States and Japan at the local level.

Neurosurgeons in Japan Are Exclusively Brain Surgeons.

PubMed

Asamoto, Shunji

2017-03-01

In Japan, neurosurgeons have traditionally mainly treated brain diseases, with most cases involving the spine and spinal diseases historically being treated by orthopedists. Nowadays, spinal surgery is 1 of the many subspecialties in the neurosurgical field in Japan. Most patients with neurological deficits or suspected neurological diseases see board-certified neurosurgeons directly in Japan, not through referrals from family physicians or specialists in other fields. Problems originating in the spine and spinal cord have been overlooked or misdiagnosed in these situations. Neurosurgeons in Japan must rethink the educational program to include advanced trauma life support and spinal surgery. Copyright © 2016. Published by Elsevier Inc.

Post and core restorations are routinely used for restoring grossly decayed tooth structures. Various chemical agents are known to affect the interfacial adhesions between the post and the core. Hence, we planned the present study to evaluate the effect of various post-surface treatments on the interfacial strength between the posts and composite materials that are used for building up the core portion. The present study included assessment of the effect of surface conditioning of posts on the interfacial adhesion in post-core restorations. A total of 80 clear post-tapers were included and were divided broadly into four study groups based on the type of chemical testing protocols used. Various chemical treatments included alkaline potassium permanganate, hydrogen peroxide, and phosphoric acid. The fourth group was the control group. The composite core material was used for building up the core. Testing of the tensile load was done on a universal testing machine. All the results were analyzed by the Statistical Package for the Social Sciences (SPSS) software. The highest bond strength was observed in the study group treated with alkaline potassium permanganate, while the lowest was observed in the control group followed by the hydrogen peroxide group. While comparing the mean bond strength in between various study groups, significant results were obtained. Chemical treatment protocol significantly alters the mean bond strength of the post and core restoration. Potassium permanganate significantly increases the bond strength between the fiber post and core restoration.

The safety and effectiveness of pemetrexed(PEM)in patients with non-small cell lung cancer(NSCLC)were reviewed using data from post-marketing surveillance. Among 699 patients registered from June 2009 to May 2010, 683 patients were analyzed(343, first-line therapy: 340, second-line therapy or beyond). Patient backgrounds were as follows: median age=65 years(16.1%B75 years old); 64.7% male; 91.9% performance status 0-1; 83.2% Stage IV; 99.0% non-squamous cell cancer. Also, 86% of the first-line and 20% of the second-line cohort were receiving a concomitant anti-cancer drug(mostly platinum agents). The incidence rate of adverse drug reactions(ADR)was 76.7%, including serious cases(18.0%). The most common ADRs were decreased white blood cell count(26.8%), decreased neutrophil count(25.3%), anemia(19.2%), decreased platelet count(17.0%), and nausea(23.0%). The incidence of interstitial lung disease, which is a concern during chemotherapy, was 2.6%. Peripheral neuropathy and alopecia, events influencing a patient's quality of life, were less than 1%. The estimated median survival time was 23.2 months[95%CI: 19.8 months-not calculable]in the first-line cohort, and 11.8 months[95% CI: 10.5-13.7 months]in the B second-line cohort. The surveillance results showed no apparent difference in total ADRs in this current study compared to the safety profile established in clinical trials previously conducted in Japan and overseas. These results demonstrate the safety and effectiveness of PEM treatment for NSCLC patients in daily clinical settings.

The aim of this study was to examine over a 12-month post-intervention period whether the participation of community-living individuals with mental illness in cognitive behavioral group therapy for recovery of self-esteem (CBGTRS) resulted in improved outcomes. This was a non-randomized controlled trial. The participants were persons with mental illness who resided in communities in the Chugoku region of Japan. In total, 41 were assigned to an experimental group (CBGTRS intervention, 12 group sessions), and 21 to a control group. Outcome indices (self-esteem, moods, cognition, subjective well-being, psychiatric symptoms) were measured for the experimental group prior to intervention (T0), immediately post-intervention (T1), and at 3 (T2) and 12 (T3) months post-intervention. The control group was measured at the same intervals. For the experimental group, self-esteem scores at T1, T2, and T3 were significantly higher than at T0. Moods and cognition scores remained significantly low until T2. Scores for Inadequate Mental Mastery in the subjective well-being index had not decreased by T3. Confidence in Coping remained significantly high until T2. Psychiatric symptoms scores at T0, T1, T2, and T3 were significantly lower than at T0. The means and standard errors for self-esteem and Inadequate Mental Mastery increased until T3, and those for Tension-Anxiety, Depression-Dejection, and Confusion decreased until T2. From within-group trends and between-group differences in self-esteem, we conclude that CBGTRS may have a relatively long-term effect on self-esteem recovery. T2 is the turning point for moods and cognition; thus, follow-up is needed 3 months following the initial program. © 2016 The Authors.

To compare the societal preferences for finger replantation between the United States (US) and Japan and to investigate factors influencing the preferences. A sample of the general population without current hand disease or condition was recruited via flyers posted in public areas of 2 major academic centers in the US and Japan. The recruited subjects completed a survey presenting finger amputation scenarios and various factors that may affect treatment decisions. We performed univariate analysis using treatment preference as the outcome and all other factors as possible predictors using the chi-square test. Most respondents in both countries preferred replantation and there was no significant difference between the US and Japan. Treatment preference was significantly associated with the importance of appearance, recovery time, and the chance of survival of the replanted digit. There was no association between treatment preference and attitudes regarding body integrity or estimate of stigma toward finger amputees. Japanese participants agreed more with statements of body integrity, and Japanese respondents rated appearance, sensation, and chance of survival of the replant as more important than did American participants. Patient preference is not driving the decrease in finger replantations in the US. The general public in both countries prefer replantation over wound closure for digit amputations.

Group A Streptococcus (GAS; Streptococcus pyogenes) causes a range of mild to severe infections in humans. It can also colonize healthy persons asymptomatically. Therefore, it is important to study GAS carriage in healthy populations, as carriage of it might lead to subsequent disease manifestation, clonal spread in the community, and/or diversification of the organism. Throat swab culture is the gold standard method for GAS detection. Advanced culture-independent methods provide rapid and efficient detection of microorganisms directly from clinical samples. We investigated the presence of GAS in throat swab samples from healthy adults in Japan using culture-dependent and culture-independent methods. Two throat swab samples were collected from 148 healthy volunteers. One was cultured on selective medium, while total DNA extracted from the other was polymerase chain reaction (PCR) amplified with two GAS-specific primer pairs: one was a newly designed 16S rRNA-specific primer pair, the other a previously described V-Na + -ATPase primer pair. Although only 5 (3.4 %) of the 148 samples were GAS-positive by the culture-dependent method, 146 (98.6 %) were positive for the presence of GAS DNA by the culture-independent method. To obtain serotype information by emm typing, we performed nested PCR using newly designed emm primers. We detected the four different emm types in 25 (16.9 %) samples, and these differed from the common emm types associated with GAS associated diseases in Japan. The different emm types detected in the healthy volunteers indicate that the presence of unique emm types might be associated with GAS carriage. Our results suggest that culture-independent methods should be considered for profiling GAS in the healthy hosts, with a view to obtaining better understanding of these organisms. The GAS-specific primers (16S rRNA and V-Na + -ATPase) used in this study can be used to estimate the maximum potential GAS carriage in people.

The radicular portion of zirconia endodontic posts often need to be reshaped to achieve a definitive form and may be airborne-particle abraded to improve adhesion during luting. Therefore, the surface of the tetragonal zirconia ceramics may be transformed and damaged, influencing the mechanical properties of the material. This study compared the fracture resistance of prefabricated zirconia posts with a new retentive post-head after different surface treatments. Experimental zirconia posts of 2 different diameters, 1.3 mm and 1.5 mm, were produced from commercially available zirconia powder. A cylindro-conical outline form was used for the root portion of the system and a post-head with 3 retentive rings was designed. Sixty posts of each diameter were divided into 3 groups (n=20). Group 1 was ground with a coarse grit diamond bur; Group 2 was airborne-particle abraded with 110-microm fused alumina particles, and Group 3 was left as-received (controls). Posts were luted into the root-shaped artificial canals with the Clearfil adhesive system and Panavia 21 adhesive resin luting agent. The posts were loaded in a universal testing machine at an inclination of 45 degrees with the constant cross-head speed of 1 mm/min. The fracture load (N) necessary to cause post fracture was recorded, and the statistical significance of differences among groups was analyzed with 1-way ANOVA followed by the Fischer LSD test (alpha=.05). The variability was analyzed using Weibull statistics. Load to fracture values of all zirconia posts depended primarily on post diameter. Mean fracture loads (SD) in Newtons were 518.4 (+/-101.3), 993.6 (+/-224.1), and 622.7 (+/-110.3) for Groups 1 through 3, respectively, for thicker posts, and 385.9 (+/-110.3), 627.0 (+/-115.1), and 451.2 (+/-81.4) for Groups 1 through 3, respectively, for thinner posts. Airborne-particle-abraded posts exhibited significantly higher resistance to fracture (P<.05) than those in the other 2 groups for diameters 1.3 mm

To investigate the genetic characteristics of the ancient populations of Hokkaido, northern Japan, polymorphisms of the ABO blood group gene were analyzed for 17 Jomon/Epi-Jomon specimens and 15 Okhotsk specimens using amplified product-length polymorphism and restriction fragment length polymorphism analyses. Five ABO alleles were identified from the Jomon/ Epi-Jomon and Okhotsk people. Allele frequencies of the Jomon/Epi-Jomon and Okhotsk people were compared with those of the modern Asian, European and Oceanic populations. The genetic relationships inferred from principal component analyses indicated that both Jomon/Epi-Jomon and Okhotsk people are included in the same group as modern Asian populations. However, the genetic characteristics of these ancient populations in Hokkaido were significantly different from each other, which is in agreement with the conclusions from mitochondrial DNA and ABCC11 gene analyses that were previously reported.

Strategic planning for post-disaster temporary housing.

PubMed

Johnson, Cassidy

2007-12-01

Temporary housing programmes suffer from excessively high cost, late delivery, poor location, improper unit designs and other inherent issues. These issues can be attributed in part to a prevalence of ad hoc tactical planning, rather than pre-disaster strategic planning, for reconstruction undertaken by governments and non-governmental organisations (NGOs) in the chaotic post-disaster environment. An analysis of the process and outcomes from six case studies of temporary housing programmes after disasters in Turkey and Colombia in 1999, Japan in 1995, Greece in 1986, Mexico in 1985, and Italy in 1976 yields information about the extent to which strategic planning is employed in temporary housing programmes, as well as common issues in temporary housing. Based on an understanding of these common issues, this paper proposes a framework for strategic planning for temporary housing that identifies organisational designs and available resources for temporary housing before the disaster, but allows modifications to fit the specific post-disaster situation.

Universal varicella vaccine immunization in Japan.

PubMed

Yoshikawa, Tetsushi; Kawamura, Yoshiki; Ohashi, Masahiro

2016-04-07

In 1974, Japanese scientists developed a live attenuated varicella vaccine based on the Oka strain. The efficacy of the vaccine for the prevention of varicella has been primarily demonstrated in studies conducted in the United States following the adoption of universal immunization using the Oka strain varicella vaccine in 1996. Although the vaccine was developed by Japanese scientists, until recently, the vaccine has been administered on a voluntary basis in Japan resulting in a vaccine coverage rate of approximately 40%. Therefore, Japan initiated universal immunization using the Oka strain varicella vaccine in November 2014. Given the transition from voluntary to universal immunization in Japan, it will also be important to monitor the epidemiology of varicella and herpes zoster. The efficacy and safety of co-administration of the varicella vaccine and measles, mumps, and rubella vaccine have been demonstrated in many countries; however, there was no data from Japan. In order to adopt the practice of universal immunization using the Oka strain varicella vaccine in Japan, data demonstrating the efficacy and safety of co-administration of varicella vaccine and measles and rubella (MR) vaccine were required. Additionally, we needed to elucidate the appropriate time interval between the first and second administrations of the vaccine. It is also important to differentiate between wild type and Oka vaccine type strains in herpes zoster patient with past history of varicella vaccine. Thus, there are many factors to consider regarding the adoption of universal immunization in Japan to control varicella zoster virus (VZV) infections. Copyright © 2016 Elsevier Ltd.

2017-03-31

The east Japan earthquake that occurred on March 11, 2011 was a big natural disaster, comprising the large earthquake shock, tsunami, and Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. These disasters caused changes in the land use and land cover (LULC) in Japan's Tohoku district. While the LULC map created before the disaster is available, as yet there is no precise LULC map of the district after the disaster. In this study, we created a precise LULC map for the years 2013-2015 post-disaster with 30-m spatial resolution using the Landsat-8 with the Operational Land Imager (OLI) to evaluate the changes in LULC induced by the disaster. Our results indicate many changes in areas categorized as rice paddies primarily into grass categories along the coast damaged by the tsunami and in the evacuation zone around the FDNPP. Since there is a possibility of future LULC changes according to the change of the evacuation zone and implementation of reconstruction and revitalization efforts, we recommend continual monitoring of the changes in LULC by the use of satellite data in order to evaluate the long-term effects of the disaster.

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.

The purpose of the present nationwide psychological autopsy case-control study is to identify the association between mental disorders and suicide in Japan, adjusting for physical conditions. A semi-structured interview was conducted of the closest family members of 49 suicide completers and 145 gender-, age-, and municipality-matched living controls. The interview included sections of socio-demographic characteristics, physical conditions, and a psychiatric interview producing DSM-IV diagnoses of mental disorders prior to suicide (or at survey). We compared prevalences of mental disorders between the two groups, using conditional logistic regression. A significantly higher proportion with any mental disorder was found in the suicide group (65.3%) compared to the control group (4.8%) (p=0.003, odds ratio [OR]=7.5). The population attributable risk proportion associated with mental disorder was 0.24. Mood disorder, particularly major depressive disorder, was the most strongly associated with suicide (p<0.001). Anxiety disorder, alcohol-related disorder, and brief psychotic disorder were also significantly associated with suicide (p<0.05). These patterns were unchanged after adjusting for serious chronic physical conditions. The present study had some limitations, such as small sample size, sampling bias and information bias. Most mental disorders, particularly mood disorder, were significantly associated with a greater risk of suicide in Japan, independent of physical conditions. Mental disorders are a major target of suicide prevention programs in Japan. Copyright © 2012 Elsevier B.V. All rights reserved.

Prader-Willi syndrome (PWS) is a genetically determined neurodevelopmental disorder characterized by mental retardation and distinct physical, behavioral, and psychiatric features. Based on parents' questionnaires, we examined the prevalence of behavioral and psychiatric disorders of 165 persons with PWS aged 2-31 years in Japan. The data were analyzed comparing four different age groups with PWS: group 1, 2-5 years (n=34); group 2, 6-11 years (n=57); group 3, 12-17 years (n=45); and group 4, 18-31 years (n=29). Further, we compared the results of our PWS group 4 with those of 42 age-, gender-, and intelligence level-matched intellectual disability (ID) individuals without PWS. Our results showed that repetitive speech and stubbornness were prominent from early childhood and other behavioral problems such as hyperphagia, stealing food, temper tantrums, lying, and emotional lability tended to be more frequent with age among persons with PWS. Moreover, young adults with PWS have significantly higher rates of behavioral and psychiatric disorders than IDs without PWS, such as stubbornness, hyperphagia, temper tantrums, self-injurious behavior (skin picking), hypersomnia, inactivity, and delusion. Degree of obesity was not necessarily related to behavioral and psychiatric features associated with PWS. Our findings revealed that persons with PWS are more vulnerable to behavioral and psychiatric disorders particularly in young adulthood compared to those with ID from other etiologies in Japan.

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.

From sword to chrysanthemum: Japan's culture of anti-miltarism

DOE Office of Scientific and Technical Information (OSTI.GOV)

Berger, T.U.

The end of the Cold War and the phenomenal increase in Japan's economic and technological power put Japan today in the position to become, if it chooses, a military as well as economic superpower. The diminution of the Soviet threat and the increasing US preoccupation with domestic problems give Japan a latitude for independent action it has not had since the end of World War II. At the same time the US-Japanese security alliance, which has enabled Japan to adopt a minimalist approach to defense and national security, is being weakened by ideologically charged trade and other economic frictions andmore » a growing American perception of Japan as a threat to its interests. Moreover, in the long run Japan faces the prospect of having to deal with other rising regional powers, most notably the People's Republic of China. This changing international security environment thus raises question whether Japan, having become an economic rival of the United States, may not in the future become a military competitor as well; whether, after having adopted a pacifist stance for half a century, Japan may choose to unsheathe its sword once again.« less

Recent findings of genetic breaks within apparently continuous marine populations challenge the traditional vicariance paradigm in population genetics. Such "invisible" boundaries are sometimes associated with potential geographic barriers that have forced divergence of an ancestral population, habitat discontinuities, biogeographic disjunctions due to environmental gradients, or a combination of these factors. To explore the factors that influence the genetic population structure of apparently continuous populations along the Sea of Japan, the sandy beach amphipod Haustorioides japonicus was examined. We sampled a total of 300 individuals of H. japonicus from the coast of Japan, and obtained partial sequences of the mitochondrial COI gene. The sequences from 19 local populations were clustered into five groups (Northwestern Pacific, Northern, Central, Southern Sea of Japan, and East China Sea) based on a spatial genetic mixture analysis and a minimum-spanning network. AMOVA and pairwise Fst tests further supported the significant divergence of the five groups. Phylogenetic analysis revealed the relationship among the haplotypes of H. japonicus and outgroups, which inferred the northward range expansion of the species. A relaxed molecular-clock Bayesian analysis inferred the early-to middle-Pleistocene divergence of the populations. Among the five clusters, the Central Sea of Japan showed the highest values for genetic diversity indices indicating the existence of a relatively stable and large population there. The hypothesis is also supported by Bayesian Skyline Plots that showed sudden population expansion for all the clusters except for Central Sea of Japan. The present study shows genetic boundaries between the Sea of Japan and the neighboring seas, probably due to geographic isolation during the Pleistocene glacial periods. We further found divergence between the populations along the apparently continuous coast of the Sea of Japan. Historical changes in the

To examine consumer perceptions, attitudes and behaviours regarding the heated tobacco product, IQOS, as well as to document the product's marketing strategies to determine its potential for appealing to youth and young adults. Truth Initiative, in collaboration with Flamingo, collected qualitative data via: (1) expert interviews, (2) semiotic analysis of IQOS packing and marketing materials, and (3) 12 focus groups with adults in Switzerland (ages 19-44 years; June 6-9, 2016) and Japan (ages 20-39 years; June 22-24, 2016) (n=68 for both groups). Expert interviews and IQOS packing and marketing analyses revealed the product is being marketed as a clean, chic and pure product, which resonated very well in Japan given the strong cultural values of order, cleanliness, quality and respect for others. Focus groups results indicated Japanese IQOS users used the product for socialising with non-smokers. Focus group participants in both Japan and Switzerland reported lower levels of satisfaction with the product relative to combustible cigarettes, although many found the product packaging to be appealing. While participants identified several benefits and barriers related to IQOS, few reported any potential health benefits of use compared with combustible tobacco products. IQOS was marketed as a sophisticated, high tech and aspirational product. Because youth and young adults are more interested in such product positioning, this approach raises some concern about youth appeal. This research shows cultural factors appeared to affect the appeal of this messaging, indicating that prevalence and uptake data will likely not be similar from country to country. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

During the American occupation of Japan (1945–1952), young public health officers from the US Army Medical Corps were posted in local US Army military government teams. These young doctors (aged 25 to 27 years), who had not absorbed the strong anti-Japanese tradition of the US military during World War II, seem to have alleviated the initial resentment felt by the Japanese toward the new governors of their homeland. The case of the Kyoto Military Government Team illustrates the Kyoto citizenry’s positive view of some American-directed public health measures. The team’s services helped to counter widely held negative views on colonialism, occupation, and public health; lessened resentment toward the unilateral command structure of the occupation forces; and contributed to improved relations between the United States and Japan at the local level.

The authors compared generational and regional trends of premature mortality from ischemic heart disease (IHD) from 1969 to 1992 for persons aged 30-69 years. They selected Tokyo and Osaka prefectures as the most urbanized and compared them with the rest of Japan. The data were divided into two periods: period I (1969-1978, International Classification of Diseases, Eight Revision) and period II (1979-1992, International Classification of Diseases, Ninth Revision). In both populations, IHD mortality decreased for both sexes, but mortality from nonspecific heart disease remained constant in men and decreased in women. In Tokyo and Osaka prefectures, the percentage decline per year in IHD mortality for both sexes was significantly smaller in period II than in period I. However, in the rest of Japan, it did not decrease for either sex. Age-specific analysis showed that the percentage decline per year in period II was smallest for the group aged 30-49 years (men, 0.05%; women, 0.76%) in Tokyo and Osaka prefectures, while it was similar for all age groups in the rest of Japan. For men, the IHD mortality rate in 1991-1992 for those aged 30-49 years was higher in Tokyo and Osaka prefectures (9.4/100,000) than in the rest of Japan (5.4/100,000).

The aim of this study is to analyse the past trends on postgraduate medical education choices and subsequent career options to discuss possible outcomes of the current shift and policy implications. Data from the national physician survey from 1976 to 2006 were analysed. The proportion change of physicians started their career in university hospitals was calculated. The career paths for physicians by different residency type were presented. More than 90% of physicians experienced university hospital work at least once in their 20-year careers. In their first 10 years of their career, physicians who started their residency in a university hospital tended to spend more years working in university hospitals, and those who started in other post-graduate training hospitals tended to spend less in university hospitals. Then, these groups presented quite similar patterns in their career choices. University hospitals need to strengthen their function as continuing education and career development centres and to adopt a less paternalistic approach, as fewer residents start their career in university hospitals.

To increase births attended by skilled birth attendants in Tanzania, studies have identified the need for involvement of the whole family in pregnancy and childbirth education. This study aimed to develop, implement, and evaluate a family-oriented antenatal group educational program to promote healthy pregnancy and family involvement in rural Tanzania. This was a quasi-experimental 1 group pre-test/post-test study with antenatal education provided to pregnant women and their families in rural Tanzania. Before and after the educational program, the pre-test/post-test study was conducted using a 34-item Birth Preparedness Questionnaire. Acceptability of the educational program was qualitatively assessed. One-hundred and thirty-eight participants (42 pregnant women, 96 family members) attended the educational program, answered the questionnaire, and participated in the feasibility inquiry. The mean knowledge scores significantly increased between the pre-test and the post-test, 7.92 and 8.33, respectively (p = 0.001). For both pregnant women and family members, the educational program improved Family Support (p = 0.001 and p = 0.000) and Preparation of Money and Food (p = 0.000 and p = 0.000). For family members, the scores for Birth Preparedness (p = 0.006) and Avoidance of Medical Intervention (reversed item) (p = 0.002) significantly increased. Despite the educational program, the score for Home-based Value (reversed item) (p = 0.022) and References of SBA (p = 0.049) decreased in pregnant women. Through group discussions, favorable comments about the program and materials were received. The comments of the husbands reflected their better understanding and appreciation of their role in supporting their wives during the antenatal period. The family-oriented antenatal group educational program has potential to increase knowledge, birth preparedness, and awareness of the need for family support among pregnant women and their

There is a widely held expectation of clinical advance with the development of gene and cell-based therapies (GCTs). Yet, establishing benefits and risks is highly uncertain. We examine differences in decision-making for GCT approval between jurisdictions by comparing regulatory assessment procedures in the United States (US), European Union (EU) and Japan. A cohort of 18 assessment procedures was analyzed by comparing product characteristics, evidentiary and non-evidentiary factors considered for approval and post-marketing risk management. Product characteristics are very heterogeneous and only three products are marketed in multiple jurisdictions. Almost half of all approved GCTs received an orphan designation. Overall, confirmatory evidence or indications of clinical benefit were evident in US and EU applications, whereas in Japan approval was solely granted based on non-confirmatory evidence. Due to scientific uncertainties and safety risks, substantial post-marketing risk management activities were requested in the EU and Japan. EU and Japanese authorities often took unmet medical needs into consideration in decision-making for approval. These observations underline the effects of implemented legislation in these two jurisdictions that facilitate an adaptive approach to licensing. In the US, the recent assessments of two chimeric antigen receptor-T cell (CAR-T) products are suggestive of a trend toward a more permissive approach for GCT approval under recent reforms, in contrast to a more binary decision-making approach for previous approvals. It indicates that all three regulatory agencies are currently willing to take risks by approving GCTs with scientific uncertainties and safety risks, urging them to pay accurate attention to post-marketing risk management.

The U.S. Department of Energy National Nuclear Security Agency’s Aerial Measuring System deployed personnel and equipment to partner with the U.S. Air Force in Japan to conduct multiple aerial radiological surveys. These were the first and most comprehensive sources of actionable information for U.S. interests in Japan and provided early confirmation to the government of Japan as to the extent of the release from the Fukushima Daiichi Nuclear Power Generation Station. Many challenges were overcome quickly during the first 48 hours; including installation and operation of Aerial Measuring System equipment on multiple U.S. Air Force Japan aircraft, flying over difficultmore » terrain, and flying with talented pilots who were unfamiliar with the Aerial Measuring System flight patterns. These all combined to make for a dynamic and non-textbook situation. In addition, the data challenges of the multiple and on-going releases, and integration with the Japanese government to provide valid aerial radiological survey products that both military and civilian customers could use to make informed decisions, was extremely complicated. The Aerial Measuring System Fukushima response provided insight in addressing these challenges and gave way to an opportunity for the expansion of the Aerial Measuring System’s mission beyond the borders of the US.« less

Male acceptance of condoms in Japan.

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.

L-Band RFI in Japan

In recent years, three instruments have been launched into orbit with the aim of producing global maps of sea surface salinity and soil moisture using the 1400-1427 MHz band: SMOS, Aquarius and SMAP. Although this frequency band is allocated to passive measurements only, RFI (Radio-Frequency Interference) is present in the data of all three missions. On a global scale, the three sensors have observed approximately the same distribution of RFI. Japan is an important exception that has implications for the design of RFI detection algorithms. RFI in Japan is caused by a large number of emitters belonging to the same system (TV receivers) and for this reason some traditional RFI detection strategies detect little to no RFI over Japan. The study of this case has led to an improvement of the approach to detect RFI in Aquarius data.

Introduction On 11 March 2011, a magnitude 9.0 earthquake caused a huge tsunami that struck Northeast Japan, resulting in nearly 20 000 deaths. We investigated mortality patterns by age, sex, and region in the 3 most severely affected prefectures. Methods Using police data on earthquake victims in Iwate, Miyagi, and Fukushima prefectures, mortality rates by sex, age group, and region were calculated, and regional variability in mortality rates across age groups was compared using rate ratios (RRs), with the rates in Iwate as the reference. Results In all regions, age-specific mortality showed a tendency to increase with age; there were no sex differences. Among residents of Iwate, mortality was markedly lower among school-aged children as compared with other age groups. In northern Miyagi and the southern part of the study area, RRs were higher among school-aged children than among other age groups. Conclusions The present study could not address the reasons for the observed mortality patterns and regional differences. To improve preparedness policies, future research should investigate the reasons for regional differences. PMID:23089585

An overview of work, retirement, and pensions in Japan.

Work to retirement in Japan is a sequential transition for the most part, and Japan permits mandatory retirement by firms at age 60. But many older people work beyond the age of 60, many more than in other industrialized countries. A number of hypotheses are examined, having to do with pensions, health, opportunity, interest in working, cultural attitudes (including the concept of ikigai), and public policy initiatives (such as employment policy and the Silver Human Resource Centers). Japan's cultural attitudes and existing policies appear to have set Japan on a unique course in considering the aging of its population. To what extent should other nations emulate Japan?

Assessing age-dependent susceptibility to measles in Japan.

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.

Post-traumatic stress disorder (PTSD) is a common psychological problem following natural disasters. Although pre-disaster risk factors are important for early detection and proactive support, the examination of such has been limited to sociodemographic factors, which were largely unaffected by the disasters. We examined the association between pre-disaster physical functioning and lifestyle and PTSD symptoms five months after the earthquake in the Great East Japan Earthquake survivors who were participating in a pre-existing cohort study. We designed a retrospective cohort study of a cooperative association in Sendai from August 2010 to August 2011. In 2010, lifestyle, physical condition, and sociodemographic factors were examined by self-reported questionnaires completed by 522 employees of this organization. We also measured the leg extension power of all the participants. PTSD symptoms were evaluated by the Japanese version of the Impact of Event Scale-Revised (IES-R-J) following the earthquake of 2011. In multivariate linear regression analysis, leg extension power (β = -0.128, P = 0.025), daily drinking (β  = 0.203, P = 0.006), and depressive symptoms (β  = 0.139, P = 0.008) were associated with total score of the IES-R-J among men. Moreover, for the IES-R-J subscale, leg extension power was also negatively associated with Intrusion (β = -0.114, P = 0.045) and Hyperarousal (β = -0.163, P = 0.004) after adjusting for all other significant variables. For women, hypertension (β  = 0.226, P = 0.032) and depressive symptoms (β  = 0.205, P = 0.046) were associated with the total score of the IES-R-J. Leg extension power is a potentially modifiable pre-disaster risk factor among men for attenuating the severity of PTSD symptoms associated with great disasters such as the Great East Japan Earthquake among men.

Program evaluations are frequently based on 'then-test' data, i.e., pre-test collected in retrospect. While the application of the then-test has practical advantages, little is known about the validity of then-test data. Because of the collection of then-test in close proximity to post-test questions, this study was aimed at exploring whether the presence of then-test questions in post-test questionnaires influenced subjects' responses to post-test. To test the influence of then-test questions, we designed a randomized three-group study in the context of chronic disease self-management programs. Interventions had comparable goals and philosophies, and all 949 study participants filled out identical Health Education Impact Questionnaires (heiQ) at pre-test. At post-test, participants were then randomized to one of the following three groups: Group A responded to post-test questions only (n = 331); Group B filled out transition questions in addition to post-test (n = 304); and Group C filled out then-test questions in addition to post-test (n = 314). Significant post-test differences were found in six of eight heiQ scales, with respondents who filled out then-test questions reporting significantly higher post-test scores than respondents of the other groups. This study provides evidence that the inclusion of then-test questions alters post-test responses, suggesting that change scores based on then-test data be interpreted with care.

The reasons for accessing and maintaining access to mental health services in Japan may be different to those in other countries. Using the World Health Organization World Mental Health Japan survey data, this study investigated the prevalence of sociodemographic correlates of barriers for the use of, reasons for delayed access to, and reasons for dropping out from mental health care in a Japanese community-based sample. An interview survey was conducted with a random sample of residents living in 11 communities across Japan during the years 2002-2006. Data from 4130 participants were analyzed. The most frequently reported reason for not seeking mental health care was a low perceived need (63.9%). The most common reason for delaying access to help was the wish to handle the problem on one's own (68.8%), while the most common reason for dropping out of care was also a low perceived need (54.2%). Being a woman and of younger age were key sociodemographic barriers to the use of mental health services. Low perceived need was a major reason for not seeking, delay in using, and dropout from mental health services in Japan. In addition, low perceived need and structural barriers were more frequently reported than attitudinal barriers, with the exception of a desire to handle the problem on one's own. These findings suggest that improving therapist-patient communication and quality of mental health care, as well as mental health literacy education in the community, might improve access to care in Japan. © 2014 The Authors.

Little is known about patient safety performance under the social insurance medical fee schedule in Japan. The Health Ministry in Japan introduced the preferential patient safety countermeasure fee (PPSCF) to promote patient safety in 2006 and revised the PPSCF system in 2010. This study aims to address the patient safety performance status at hospitals implementing the PPSCF. A nationwide questionnaire survey targeting 2674 hospitals with the PPSCF was performed in 2010 to 2011. The 627 participant hospitals were divided into the following three groups: 178 hospitals implementing PPSCF 1 with 400 beds or more (group A), 286 hospitals implementing PPSCF 1 with 399 beds or fewer (group B), and 163 hospitals implementing PPSCF 2 (group C). The mean numbers (standard errors) of patient safety managers were 1.45 (0.07) in group A, 1.12 (0.04) in group B, and 0.37 (0.12) in group C (P < 0.001). The participation number and rates of all staff for the patient safety seminar were 1721 (167) and 1.64 (0.10) in group A, 580 (26) and 1.94 (0.09) in group B, and 349 (31) and 1.98 (0.17) in group C (P < 0.001, P = 0.105).These results can be explained because hospitals with PPSCF 1 (groups A and B) must assign at least one full-time patient safety manager, whereas hospitals with PPSCF 2 (group C) are not required to do so. Patient safety performance at hospitals with PPSCF 1 was more active than that at hospitals with PPSCF 2. However, when the values were converted to per capita or per 100 beds, there were no differences across the three groups. The PPSCF encourages hospitals to perform actions for patient safety by providing incentives under the social insurance medical fee schedule in Japan.

Post retention: the effect of sequence of post-space preparation, cementation time, and different sealers.

Many endodontic sealers contain constituents that have been shown to inhibit the polymerization of resin cements. This may be important when prefabricated posts are cemented at the same appointment as root canal obturation. This study evaluated the effects of cementing posts with a resin cement immediately or at a delayed time period after obturation using Roth's 801 Elite Grade or AH26 sealer cements. The contribution of mechanical post-space preparation was also assessed as a critical variable. One hundred twenty extracted canines were randomly divided into eight experimental groups. The variables evaluated were the order of post preparation (either before or after obturation), the type of sealer used, and the time of post cementation. All teeth received a stainless steel #6 Parapost XP cemented with a resin cement, Panavia 21. Each experimental group underwent tensile testing for retention using an Instron universal testing machine. For both sealers posts cemented in teeth in which the canal was obturated before post-space preparation and thus had sealer-contaminated dentin removed by the space preparation procedure had significantly higher retentive values than those obturated after post-space preparation in which contaminated dentin might remain. Sealer used and time of cementation had no specific effect on retention. Achieving a clean, "freshened" dentinal surface during mechanical post-space preparation seems to be a critical variable for post retention when a resin cement is used.

The origins of Japan's medical ideas, which are deeply rooted in its religion, culture and history, are not widely understood in medical societies of other countries. We have taken up the task of summarising this tradition here so that some insight can be gained into the unique issues that characterise the practice of medicine in Japan. We borrow from the sayings of Tohkaku Wada, a medical philosopher of late eighteenth-century Japan, for a look at Japanese medical tradition. Wada's medical thought was very much reflective of the Buddhism, Zen, and swordsmanship that informed eighteenth-century philosophy in Japan. His central concepts were "chu" and "sei", that is, complete and selfless dedication to the patient and the practice of medicine. This paper explores Wada's thought, explaining it mainly from the standpoint of Japanese traditional culture. Key Words: Tohkaku Wada • ethics • philosophy • Buddhism • Zen • Japan PMID:11233381

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

There become problems about a delay on clinical development of anticancer drug in Japan and drug lag. I consider causes and solutions of the problems from a position of drug approval reviewer. I think the drug lag may cause by stating later state in global clinical development or stagnation of clinical trial activities. To prevail against drug lag,it is necessary to attend to multinational clinical studies,and to mature Japanese clinical trial environment and post-market planning. Then, I believe that the most important point is to make a start on early stage of global clinical development.

Japan has had high rates of transition to nursing homes from other long term care facilities. It has been hypothesized that care transitions occur because a resident's condition deteriorates. The aim of the present study was to compare the health care and personal care needs of residents in nursing homes, group homes, and congregate housing in Japan. The present study was conducted using a cross-sectional study design. The present study included 70,519 elderly individuals from 5 types of residential facilities: care medical facilities (heavy medical care; n = 17,358), geriatric intermediate care facilities (rehabilitation aimed toward a discharge to home; n = 26,136), special nursing homes (permanent residence; n = 20,564), group homes (group living, n = 1454), and fee-based homes for the elderly (congregate housing; n = 5007). The managing director at each facility provided information on the residents' health care and personal care needs, including activities of daily living (ADLs), level of required care, level of cognitive impairment, current disease treatment, and medical procedures. A multinomial logistic regression analysis demonstrated a significantly lower rate of medical procedures among the residents in special nursing homes compared with those in care medical facilities, geriatric intermediate care facilities, group homes, and fee-based homes for the elderly. The residents of special nursing homes also indicated a significantly lower level of required care than those in care medical facilities. The results of our study suggest that care transitions occur because of unavailable permanent residence option for people who suffer with medical deterioration. The national government should modify residential facilities by reorganizing several types of residential facilities into nursing homes that provide a place of permanent residence.

Objectives: Post-traumatic growth (PTG) and its opposite—post-traumatic depreciation (PTD)—may be treated as important indicators of the patient quality of life. In the absence of studies on both, PTG and PTD in cancer patients, we investigated (1) coping strategies and support effectiveness as predictors of PTG and PTD in post-mastectomy women, (2) homogeneous classes with different intensity of PTG and PTD symptoms, and (3) correlates of class membership. Methods: Coping strategies (Brief COPE), support effectiveness (SSE-Q), PTG (PTGI), and PTD (negatively reworded items of PTGI) were measured in 84 post-mastectomy women (mean age = 62.27, SD = 8.38). Multiple regression, two-step cluster, and multinomial logistic regression were applied. Results: PTG and PTD had unique predictors: time since diagnosis and positive emotion-focused coping predicted PTG (R2 = 0.24), while negative emotion-focused and avoidance-focused coping and low support effectiveness were linked to PTD (R2 = 0.14). Four groups of PTG × PTD symptoms were identified: high PTG low PTD group (52.4%), low PTG low PTD group (17.9%), high PTG high PTD group (15.5%), and low PTG high PTD group (14.3%). Higher emotion- and avoidance-focused coping was characteristic for the high PTD low PTG group (R2 = 0.41). Conclusion: Our findings shed light on the coexistence and unique predictors of PTG and PTD after mastectomy, indicating heterogeneity in PTG and PTD levels among post-mastectomy women.

Objectives: Post-traumatic growth (PTG) and its opposite-post-traumatic depreciation (PTD)-may be treated as important indicators of the patient quality of life. In the absence of studies on both, PTG and PTD in cancer patients, we investigated (1) coping strategies and support effectiveness as predictors of PTG and PTD in post-mastectomy women, (2) homogeneous classes with different intensity of PTG and PTD symptoms, and (3) correlates of class membership. Methods: Coping strategies (Brief COPE), support effectiveness (SSE-Q), PTG (PTGI), and PTD (negatively reworded items of PTGI) were measured in 84 post-mastectomy women (mean age = 62.27, SD = 8.38). Multiple regression, two-step cluster, and multinomial logistic regression were applied. Results: PTG and PTD had unique predictors: time since diagnosis and positive emotion-focused coping predicted PTG ( R 2 = 0.24), while negative emotion-focused and avoidance-focused coping and low support effectiveness were linked to PTD ( R 2 = 0.14). Four groups of PTG × PTD symptoms were identified: high PTG low PTD group (52.4%), low PTG low PTD group (17.9%), high PTG high PTD group (15.5%), and low PTG high PTD group (14.3%). Higher emotion- and avoidance-focused coping was characteristic for the high PTD low PTG group ( R 2 = 0.41). Conclusion: Our findings shed light on the coexistence and unique predictors of PTG and PTD after mastectomy, indicating heterogeneity in PTG and PTD levels among post-mastectomy women.

The intake of total aflatoxins (AFT) and aflatoxin B(1) (AFB(1)) from food in Japan was estimated from AFT and AFB(1) concentration and frequency data in 24 foods (884 samples) from a 3-year retail market survey from the summer of 2004 to the winter of 2006, and by food consumption data from the National Health and Nutrition Survey performed in 2005. The AFT and AFB(1) survey revealed that peanut, peanut products, cocoa, chocolate, pistachio, white pepper, red pepper, almond, job's tears, buckwheat and corn grits are considered to be contributors of AFT (or AFB(1)) intake in Japan (maximum AFB(1) (AFT) levels ranged from 0.21 to 28.0 microg kg(-1) (from 0.21 to 9.0 microg kg(-1))) in AFT-contaminated food. A probabilistic approach using the Monte Carlo method was carried out to simulate an estimate of the AFT (or AFB(1)) intake distributions in each age group in Japan. In this study, AFB(1) intake ranged from 0.003 to 0.004 ng kg(-1) body weight day(-1) (from lower to upper limits), and the potential risk for cancer using a formula devised by the Joint Food and Agricultural Organization/World Health Organization (FAO/WHO) Expert Committee on Food Additives (JECFA) was estimated at 0.00004-0.00005 person/year/100,000 persons, even though this was in the higher levels (95.0th percentile) of the consumer population. The results suggest that the current dietary intake of AFB(1) in Japan has no appreciable effect on health.

The patterns of association between age and suicide rate vary by country, subpopulation and gender, and over time. To shed light on factors associated with these differences, we analysed suicide data from four populations, two 'Western' (Australia, the United States [US]) and two Asian (Japan and Hong Kong). We computed suicide rates in five-year age-groups (between 10 and 14 years and 85+ years) for men and women separately, and present graphical representations of the age patterns during selected five-year periods. Rates and age patterns differed markedly, as did gender patterns except in Hong Kong. In 1964-8, male suicide rates in Australia and US were represented by upward-sloping graphs, whereas in Japan the pattern was bimodal. By 1979-83, male patterns in Australia and US were bimodal, but Japan's was trimodal, including a middle-age peak reached in 1994-98. In contrast, female age patterns in the Western countries were shallowly convex or uniform, while in Hong Kong and Japan the upward-sloping graphs became, over time, less steep; by 2009-13, the pattern in Japan was uniform (flat). In recent decades, suicide rates of older men in Australia, US and Japan, and older women in Japan and Hong Kong, have fallen considerably. Suicide rates of men aged 45-64 in Australia and US also fell, though by 2009-13 the US rate had risen again. The suicide rate of Australian men in their twenties halved between 1994-98 and 2009-13, while rates for younger men and women in Japan have risen since 1994-98. In Hong Kong, suicide rates of young men have increased. Age patterns of suicide likely reflect period and cohort effects shaped by socioeconomic stressors, availability of health and welfare services, access to lethal methods of suicide, and other factors. Greater understanding of their impact on age patterns of suicide can result in potential preventive solutions. Copyright © 2017 Elsevier B.V. All rights reserved.

The aim of this ex-vivo study was to evaluate the impact of cavity size and glass-fiber post (GFP) placement on the load capability of endodontically treated maxillary incisors directly restored with resin composite. Ninety-six extracted human maxillary central incisors were endodontically treated and distributed to four groups (n = 24): access cavity (A), access cavity and uni-proximal class III cavity (U), access cavity and bi-proximal class III cavity (B), and decoronated tooth (D). Specimens were restored with resin composite, and 12 specimen of each group received an adhesively placed glass-fiber post (P). Prior to linear loading, specimens were exposed to thermo-mechanical loading (TCML). Statistical analysis was performed using log-rank test after TCML, Kruskall-Wallis and Mann-Whitney U test to compare load capabilities (F max) . Significantly more failures occurred in group D for specimens without GFP during TCML (p = 0.001). F max (mean (SD) in N was (A) 513 (124), (AP) 554 (201), (U) 438 (171), (UP) 537 (232) (B) 483 (219), (BP) 536 (281), D 143 (181), and DP 500 (331), and differed significantly among groups (p = 0.003). Pair-wise comparison revealed lower F max values for group D compared to all other groups (p < 0.034) except group DP. Endodontically treated maxillary central incisors with cavity sizes up to bi-proximal class III may be successfully directly restored with resin composite. Post placement shows no additional effect except for decoronated endodontically treated incisors. Endodontically treated incisors with access cavities to class III cavities can be successfully restored with resin composite. Post placement for decoronated ETT is recommended.

Fiber posts are widely used for restoration of mutilated teeth that lack adequate coronal tooth structure to retain a core for definitive restoration, bond between the fiber post and composite material depends upon the chemical reaction between the post surface and the resin material used for building up the core. In attempt to maximize the resin bonding with fiber post, different post surface conditioning is advocated. Therefore the purpose of the study is to examine the interfacial strength between fiber post and composite, as core build-up material after different surface treatments of fiber posts. Twenty fiber posts were split into four groups off five each according to different surface treatments viz. Group I-(Negative Control), Group II-Silanization (Positive control), Group III-(37% Phosphoric Acid & Silanization) ,Group IV- (10% Hydrogen Peroxide and Silanization). With the preformed plastic mould, a core of dual cure composite resin around the fiber post having the uniform thickness was created. Tensile bond strength of each specimen was measured under Universal Testing Machine (UTM) at the cross head speed of 3mm/min. The results achieved with 10% Hydrogen peroxide had a marked effect on micro tensile bond strength values between the tested materials. Immense enhancement in the silanization efficiency of quartz fiber phase was observed with different surface chemical treatment of the resin phase of fiber posts with the marked increase in the micro-tensile bond strength between fiber post and composite core.

Genetic divergence in nuclear genomes between populations of Fagus crenata along the Japan Sea and Pacific sides of Japan.

Hiraoka, Koichi; Tomaru, Nobuhiro

2009-05-01

Genetic diversity and structure in Fagus crenata were studied by analyzing 14 nuclear microsatellite loci in 23 populations distributed throughout the species' range. Although population differentiation was very low (F (ST) = 0.027; R (ST) = 0.041), both neighbor-joining tree and Bayesian clustering analyses provided clear evidence of genetic divergence between populations along the Japan Sea (Japan Sea lineage) and Pacific (Pacific lineage) sides of Japan, indicating that physical barriers to migration and gene flow, notably the mountain ranges separating the populations along the Japan Sea and Pacific sides, have promoted genetic divergence between these populations. The two lineages of the nuclear genome are generally consistent with those of the chloroplast genome detected in a previous study, with several discrepancies between the two genomes. Within-population genetic diversity was generally very high (average H (E) = 0.839), but decreased in a clinal fashion from southwest to northeast, largely among populations of the Japan Sea lineage. This geographical gradient may have resulted from the late-glacial and postglacial recolonization to the northeast, which led to a loss of within-population genetic diversity due to cumulative founder effects.

OBJECTIVE: To compare lung function between patients with post-poliomyelitis syndrome and those with sequelae of paralytic poliomyelitis (without any signs or symptoms of post-poliomyelitis syndrome), as well as between patients with post-poliomyelitis syndrome and healthy controls. METHODS: Twenty-nine male participants were assigned to one of three groups: control; poliomyelitis (comprising patients who had had paralytic poliomyelitis but had not developed post-poliomyelitis syndrome); and post-poliomyelitis syndrome. Volunteers underwent lung function measurements (spirometry and respiratory muscle strength assessment). RESULTS: The results of the spirometric assessment revealed no significant differences among the groups except for an approximately 27% lower mean maximal voluntary ventilation in the post-poliomyelitis syndrome group when compared with the control group (p = 0.0127). Nevertheless, the maximal voluntary ventilation values for the post-poliomyelitis group were compared with those for the Brazilian population and were found to be normal. No significant differences were observed in respiratory muscle strength among the groups. CONCLUSIONS: With the exception of lower maximal voluntary ventilation, there was no significant lung function impairment in outpatients diagnosed with post-poliomyelitis syndrome when compared with healthy subjects and with patients with sequelae of poliomyelitis without post-poliomyelitis syndrome. This is an important clinical finding because it shows that patients with post-poliomyelitis syndrome can have preserved lung function. PMID:24068267

This study examines the acculturation effects on metabolic syndrome (MetS), and its related factors, among immigrant Japanese-Brazilian men in Japan. Quantitative and qualitative approaches were utilized. In the quantitative study (n = 149), multiple logistic regression analyses estimated the impact of length of residence and arrival age on MetS. For the qualitative study, five focus group discussions were conducted with participants (n = 26) from the quantitative study sample. The oldest arrival age group was more likely to have MetS (OR, 95% CI 4.41, 1.09-17.78) after adjusting for covariates; whereas, length of residence had no association with MetS. The oldest arrival age group, with shorter residence period, was also associated with increased MetS prevalence. Qualitative results identified participants' Brazilian dietary habits as being potential risk factors for MetS. Japanese-Brazilian immigrant men with older arrival age in Japan were more likely to suffer from MetS, especially shortly after arrival.

Insulinoma as rare cause of severe post-partum hypoglycemia.

Holstein, Andreas; Morgenstern, Thomas; Dienst, Henry; Hiller, Wolfgang

2015-11-01

Post-partum hypoglycemia in non-diabetic women is a rare condition. We report the exceptional case of a 38-year-old obese woman who experienced recurrent neuroglycopenia 3 weeks after delivery. Corresponding to severe hypoglycemia with blood glucose levels of <30 mg/dL, there was no suppression of insulin or C-peptide. Through endoscopic ultrasound we detected a hypoechoic lesion of 8 × 9 mm localized in the head of the pancreas. Thus, the diagnosis of insulinoma was most probable. Complete surgical enucleation of the insulinoma resulted in immediate and permanent resolution of hypoglycemia. The postoperative course was complicated by recurrent episodes of pancreatitis requiring endoscopic ultrasound-guided punctures of pseudocysts and temporary stenting of the pancreatic duct. In conclusion, insulinoma is a very rare, nonetheless important, differential diagnosis of post-partum hypoglycemia. © 2015 Japan Society of Obstetrics and Gynecology.

Approximately 70,000 Japan Ground Self-Defense Force (JGSDF) personnel were dispatched in the wake of the 2011 Great East Japan Earthquake and the tsunami and nuclear disaster that followed. This study was conducted to evaluate the mental health of the JGSDF personnel and the correlates. Data collected from 56,753 participants at three time points (one, six, and 12 months after mission completion) were analyzed. Those who scored 25 or more points on the Impact of Events Scale-Revised (IES-R) and the Kessler Psychological Distress Scale (K10) were allocated into the high posttraumatic stress response (high-PTSR) group, and the high general psychological distress (high-GPD) group, respectively. The multiple logistic regression analysis identified the following factors as the significant risk factor related to high-PTSR or high-GPD status, with odds ratios of 2.0 or higher: deployment length of three or more months, being personally affected by the disaster, and being overworked continuously for three or more months after mission completion. No significant association was observed for duties with radiation exposure risk. Our findings suggest that disaster workers may be able to conduct disaster relief activities more safely with mission-related considerations of shorter deployment length and recognizing the effects on personnel personally affected by the disaster, in addition to avoiding overworking personnel after mission completion.

Per the 2014 Japanese Midwives Association (JMA) guidelines, midwives were allowed to manage the deliveries for group B streptococcus (GBS)-positive pregnant women in labour at maternity homes without the supervision of a medical doctor if they complied with the guidelines of the Japan Society of Obstetrics and Gynecology (JSOG), wherein midwives working for maternity homes are expected to cooperate with commissioned obstetricians and paediatricians in cooperative medical facilities. We examined the rate of compliance with these JMA and JSOG guidelines regarding the management of GBS-positive pregnant women among midwives at maternity homes in Japan. Between October and December 2015, an anonymous questionnaire was distributed to 337 maternity homes registered with the JMA by mail. The questionnaire obtained information regarding the timing of GBS screening, specimen collection, transfer of GBS-positive pregnant women from a maternity home to a hospital, administration of intrapartum antibiotic prophylaxis, and collaboration between midwives and commissioned obstetricians. Data were analysed using descriptive statistics. We used frequency distribution as the statistical test. Responses were received from 246 (73.0%) maternity homes, of which complete responses from 204 maternity homes (valid response rate, 60.5%) were analysed. Of these 204 maternity homes, only 97 (47.5%) conducted a GBS screening test during 33-37 weeks of gestation as recommended by the JSOG guidelines. Although midwives alone managed GBS-positive pregnant women in labour at 135 maternity homes (66.2%), intrapartum antibiotic prophylaxis, as recommended by the JSOG guidelines, was conducted in only 111 (54.4%). Moreover, only 37.0% (50/135) and 82.2% (111/135) of maternity homes ensured that GBS-positive pregnant women in labour with an elapse of ≥18 h after PROM and a body temperature of ≥38.0 °C, respectively, were transferred to a hospital by ambulance.

Why caution is recommended with post-hoc individual patient matching for estimation of treatment effect in parallel-group randomized controlled trials: the case of acute stroke trials.

PubMed

Jafari, Nahid; Hearne, John; Churilov, Leonid

2013-11-10

A post-hoc individual patient matching procedure was recently proposed within the context of parallel group randomized clinical trials (RCTs) as a method for estimating treatment effect. In this paper, we consider a post-hoc individual patient matching problem within a parallel group RCT as a multi-objective decision-making problem focussing on the trade-off between the quality of individual matches and the overall percentage of matching. Using acute stroke trials as a context, we utilize exact optimization and simulation techniques to investigate a complex relationship between the overall percentage of individual post-hoc matching, the size of the respective RCT, and the quality of matching on variables highly prognostic for a good functional outcome after stroke, as well as the dispersion in these variables. It is empirically confirmed that a high percentage of individual post-hoc matching can only be achieved when the differences in prognostic baseline variables between individually matched subjects within the same pair are sufficiently large and that the unmatched subjects are qualitatively different to the matched ones. It is concluded that the post-hoc individual matching as a technique for treatment effect estimation in parallel-group RCTs should be exercised with caution because of its propensity to introduce significant bias and reduce validity. If used with appropriate caution and thorough evaluation, this approach can complement other viable alternative approaches for estimating the treatment effect.

Endemism of subterranean Diacyclops in Korea and Japan, with descriptions of seven new species of the languidoides-group and redescriptions of D. brevifurcus Ishida, 2006 and D. suoensis Ito, 1954 (Crustacea, Copepoda, Cyclopoida)

Abstract Copepods have been poorly studied in subterranean habitats in Korea. Previous records have indicated mostly the presence of species already described from Japan, with very few endemic elements. This commonality has usually been explained by repeated dispersal across the land bridges that connected the two countries several times during the Pleistocene glacial cycles. However, the Korean Peninsula is known for pockets of Cambrian and Ordovician carbonate rocks, with more than 1,000 caves already having been explored. The relative isolation of these carbonate pockets makes for an enormous speciation potential, and the development of a high level of short-range endemism of subterranean copepods should be expected. Representatives of the genus Diacyclops Kiefer, 1927 are here investigated from a range of subterranean habitats in South Korea, with comparative material sampled from central Honshu in Japan. Morphological analyses of microcharacters, many of which are used in cyclopoid taxonomy for the first time herein, reveal high diversity in both countries. No subterranean species is found in common, although the existence of four sibling species pairs in Korea and Japan may be indicative of relatively recent speciation. We describe seven new stygobiotic species, including three from Korea (Diacyclops hanguk sp. n., Diacyclops leeae sp. n., and Diacyclops parasuoensis sp. n.) and four from Japan (Diacyclops hisuta sp. n., Diacyclops ishidai sp. n., Diacyclops parahanguk sp. n., and Diacyclops pseudosuoensis sp. n.). Diacyclops hanguk, Diacyclops parasuoensis, Diacyclops ishidai, and Diacyclops parahanguk are described from newly collected material, while the other three new species are proposed for specimens previously identified as other, widely distributed species. Diacyclops brevifurcus Ishida, 2006 is redescribed from the holotype female, and Diacyclops suoensis Ito, 1954 is redescribed from material newly collected near the ancient Lake Biwa in Japan

Intracranial germ cell tumors (GCTs) are relatively rare. Their incidence has been considered to be higher in East Asia than in the United States. This study estimates the incidence of CNS GCTs in Japan and the United States, investigates gender discrepancies in each country, and describes treatment outcomes. Data on primary CNS GCTs from 4 databases were utilized: population-based malignant incidence data from (1) the Japan Cancer Surveillance Research Group (2004–2006; 14 registries), malignant and nonmalignant incidence data from (2) the Surveillance, Epidemiology, and End Results Program (2004–2008; 17 registries), and hospital-based observed survival data from (3) the Brain Tumor Registry of Japan (1984–2000) and (4) the US National Cancer Data Base (1990–2003). Incidence rates per 100 000 for malignant GCTs were not statistically significantly different between Japan (males = 0.143, females = 0.046) and the United States (males = 0.118, females = 0.030). The malignant incidence-rate ratio was higher for pineal GCTs versus nonpineal (ie, the rest of the brain) GCTs in Japan (11.5:1 vs 1.9:1, respectively) and the United States (16.0:1 vs 1.7:1, respectively). In general, 5-year survival estimates were high: over 75% for all GCTs, and over 81% for germinomas, regardless of the type of treatment in either Japan or the United States. The incidence of primary GCTs is similar between Japan and the United States and has the same gender-based patterns by location. High rates of survival were observed in both countries. PMID:22869621

Unilateral introgression from diploids to tetraploids has been hypothesized to be an important evolutionary mechanism in plants. However, few examples have been definitively identified, perhaps because data of sufficient depth and breadth were difficult to obtain before the advent of affordable high-density genotyping. Throughout Japan, tetraploid Miscanthus sacchariflorus and diploid Miscanthus sinensis are common, and occasionally hybridize. In this study, 667 M. sinensis and 78 M. sacchariflorus genotypes from Japan were characterized using 20 704 SNPs and ten plastid microsatellites. Similarity of SNP genotypes between diploid and tetraploid M. sacchariflorus indicated that the tetraploids originated through autopolyploidy. Structure analysis indicated a gradient of introgression from diploid M. sinensis into tetraploid M. sacchariflorus throughout Japan; most tetraploids had some M. sinensis DNA. Among phenotypically M. sacchariflorus tetraploids, M. sinensis ancestry averaged 7% and ranged from 1–39%, with introgression greatest in southern Japan. Unexpectedly, rare (~1%) diploid M. sinensis individuals from northern Japan were found with 6–27% M. sacchariflorus ancestry. Population structure of M. sinensis in Japan included three groups, and was driven primarily by distance, and secondarily by geographic barriers such as mountains and straits. Miscanthus speciation is a complex and dynamic process. In contrast to limited introgression between diploid M. sacchariflorus and M. sinensis in northern China, selection for adaptation to a moderate maritime climate probably favoured cross-ploidy introgressants in southern Japan. These results will help guide the selection of Miscanthus accessions for the breeding of biomass cultivars. PMID:25618143

Divorce in contemporary Japan.

Data from the 1985-86 Japanese census are analysed to explore the determinants of the divorce rates in Japan's forty-seven prefectures, using two theoretical models: (a) the social integration model, which is shown to have a greater utility in predicting Japanese divorce levels than (b), the human capital model. Female emigration patterns play a significant role in affecting the divorce rate. Population increase and net household income are also important predictors of the Japanese divorce rate and urbanization has a great influence in modern Japan. Demographic and aggregate variables such as migration, urbanization, and socioeconomic factors are useful when organized under a social integration model.

In 2003, Japan introduced the prospective payment system (PPS) with diagnosis-related groups (DRG) rearranged grouping system called the diagnostic procedure combination/per-diem payment system (DPC/PDPS). Even after eight years, little is known about the effects of DPC/PDPS. The purpose of this study was to examine the effects of DPC/PDPS on resource usage and healthcare quality. Using 2001-2009 (fiscal year) administrative data of acute myocardial infarction patients, four indices, including inpatient total accumulated medical charges, length of stay (LOS), mortality rate, and readmission rate, were compared between patients reimbursed by DPC/PDPS or by fee-for-service. DPC/PDPS significantly reduced total accumulated medical charges by $1061 (95% confidence interval [CI], -2007, -116) and LOS by 2.29 days (95% CI, -3.71, -0.88) after risk adjustment. However, mortality rate (Odds ratio [OR], 0.94; 95% CI, 0.73, 1.21) was unchanged. Furthermore, DPC/PDPS increased the readmission rate (OR, 1.37; 95% CI, 1.03, 1.82). This study showed that DPC/PDPS was associated with reduced resource usage, but not improved healthcare quality, as with DRG/PPSs in other countries. To achieve successful healthcare reform, further discussion on additional motives will be required. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

To determine the prevalence and effect of dietary habits on functional constipation in preschool and early elementary school children in Japan. A total of 3595 children aged 3 to 8 years from 28 nursery schools and 22 elementary schools in Yokohama City, Kanagawa Prefecture, Japan, were evaluated. The subjects were divided into a functional constipation group and a nonfunctional constipation group according to the Rome III criteria. Dietary intake data were collected using a brief-type, self-administered, diet-history questionnaire validated for Japanese preschool-aged children. Of the 3595 subjects evaluated, 718 (20.0%) had functional constipation. The association between functional constipation and gender was not statistically significant ( p = 0.617). A decrease in bowel frequency was observed in 15.9% of those with functional constipation. There was no significant difference in the proportion of participants in the constipation group by age ( p = 0.112). Binomial logistic regression analysis indicated that only fat per 100 kcal positively correlated with functional constipation [odds ratio = 1.216, 95% confidence interval: 1.0476-1.412]. Functional constipation is common among children in preschool and early elementary school in urban areas of Japan. Parents should pay attention to constipation-related symptoms other than defecation frequency. A high-fat diet should be avoided to prevent functional constipation.

Tsunami source is the origin of the subsequent transoceanic water waves, and thus the most critical component in modern tsunami forecast methodology. Although impractical to be quantified directly, a tsunami source can be estimated by different methods based on a variety of measurements provided by deep-ocean tsunameters, seismometers, GPS, and other advanced instruments, some in real time, some in post real-time. Here we assess these different sources of the devastating March 11, 2011 Japan tsunami by model-data comparison for generation, propagation and inundation in the near field of Japan. This study provides a comparative study to further understand the advantages and shortcomings of different methods that may be potentially used in real-time warning and forecast of tsunami hazards, especially in the near field. The model study also highlights the critical role of deep-ocean tsunami measurements for high-quality tsunami forecast, and its combination with land GPS measurements may lead to better understanding of both the earthquake mechanisms and tsunami generation process. ?? 2011 MTS.

Predictors of post-partum stress in Vietnamese immigrant women in Taiwan.

The post-partum period is a stressful time of change, particularly for immigrant women, but, to the best of the present authors' knowledge, the subject has not been explored. This study aimed to examine immigrant women's post-partum stress, depression, and levels of social support, and to determine the predictors of post-partum stress for Vietnamese immigrant women in Taiwan. A cross-sectional design was used. In this descriptive survey, 208 Vietnamese immigrant women were telephone interviewed by a trained Vietnamese research assistant during one of their 6 weeks post-partum. Data were collected through telephone interviews using three questionnaires, including the Hung Postpartum Stress Scale, Beck Depression Inventory, and Social Support Scale. The result shows that Vietnamese women had low level post-partum stress scores. Participants' family support rated higher than friend support. The incidence of depression was 0.5%. Social support, number of post-partum days, and family income were found to be predictors for post-partum stress, accounting for 26.6% of the variance. The Vietnamese immigrant women experienced significant stress regarding their maternal roles and received most of their support from their families rather than from friends. Nurses caring for this cohort should therefore consider these factors in order to help them cope with their post-partum stress. Healthcare providers should offer available resources to these immigrant women and their spouses during this critical period in their lives. For instance, antenatal education classes could be provided to help immigrant women manage and overcome post-partum issues. © 2015 Japan Academy of Nursing Science.

Tobacco use interventions in surgical patients who smoke could benefit both their short-term outcome and long-term health. Anaesthesiologists and surgeons can play key roles in delivering these interventions. This study determined the practices, attitudes, and beliefs of these physicians regarding tobacco use interventions in Japan. Questionnaires were mailed to a national random sampling of Japanese anaesthesiologists and thoracic surgeons (1000 in each group). The survey response rate was 62%. More than 80% of respondents agreed or strongly agreed with the statements affirming the benefits of abstinence to surgical patients. However, only 26% of surgeons and 6% of anaesthesiologists reported almost always providing help to their patients to quit smoking. Compared with anaesthesiologists, surgeons were more likely to perform the elements of current recommendations for brief intervention, and to have attitudes favourable to tobacco use interventions. The most significant barrier to intervention identified by both groups was a lack of time to perform counselling. Compared with non-smokers, physicians who smoked were less likely to perform each of the recommended tobacco interventions Although current rates of intervention provided by anaesthesiologists and surgeons are low, there is considerable interest among these physicians in learning more about interventions. Given the relatively high prevalence of smoking in Japan and the potential for surgery to serve as a 'teachable moment' to promote abstinence from smoking, leadership by these specialists in the area of tobacco control could have a major impact on public health in Japan.

AIM: To examine the prevalence of gastroesophageal reflux disease (GERD) symptoms in a large unselected general population in Japan. METHODS: In Japan, mature adults are offered regular check-ups for the prevention of gastric cancer. A notice was sent by mail to all inhabitants aged > 40 years. A total of 160 983 Japanese (60 774 male, 100 209 female; mean age 61.9 years) who underwent a stomach check up were enrolled in this study. In addition, from these 160 983 subjects, we randomly selected a total of 82 894 (34 275 male, 48 619 female; mean age 62.4 years) to evaluate the prevalence of abdominal pain. The respective subjects were prospectively asked to complete questionnaires concerning the symptoms of heartburn, dysphagia, and abdominal pain for a 1 mo period. RESULTS: The respective prevalences of the symptoms in males and females were: heartburn, 15.8% vs 20.7%; dysphagia, 5.4% vs 7.8%; and abdominal pain, 6.6% vs 9.6%. Among these symptoms, heartburn was significantly high compared with the other symptoms, and the prevalence of heartburn was significantly more frequent in females than in males in the 60-89-year age group. Dysphagia was also significantly more frequent in female patients. CONCLUSION: The prevalence of typical GERD symptoms (heartburn) was high, at about 20% of the Japan population, and the frequency was especially high in females in the 60-89 year age group.
