Abstract
Over the past two decades, the use of telemedicine as a way to provide medical services has grown as communication technologies advance and patients seek more convenient ways to receive care. Because developments within this field are still rapidly evolving, identifying trends within telemedicine literature is an important task to help delineate future directions of telemedicine research. In this study, we analyzed 7960 telemedicine-related publication records found in the Science Citations Index - Expanded database between 1993 and 2012. Bibliometric analyses revealed that while the total growth in telemedicine literature has been significant in the last twenty years, the publication activity per country and over time has been variable. While the United States led the world in the cumulative number of telemedicine publications, Norway ranked highest when we ordered countries by publications per capita. We also saw that the growth in the number of publications per year has been inconsistent over the past two decades. Our results identified that neuroscience neurology and nursing as two fields of research in telemedicine that have seen considerable growth in interest in this field, and are poised to be the focus of research activity in the near future.

Abstract
Currently, interventions for HIV/AIDS control in Sri Lanka are only carried out among the most-at-risk populations. This study was conducted to identify the level of awareness and stigma-related attitudes among the general population of Sri Lanka. A cross-sectional study was carried out among 869 residents of 18-64 years of age in Kandy, Sri Lanka. A self-administered questionnaire was utilised to obtain information about stigma, discrimination and HIV/AIDS-related knowledge. Chi-square test and multivariate analysis were applied to find possible associations between HIV-related variables and socio-demographic indicators. Response rate was 82.0%. Overall, 93.5% of the participants have heard of HIV/AIDS but the knowledge on HIV/AIDS was low with an average score of 51.7%, no statistically significant difference between genders (p = 0.352). Only 58.1% were aware that a condom was an effective tool for its prevention. There were many misconceptions related to epidemiology of HIV/AIDS. The participants showed more positive attitudes towards HIV/AIDS and people living with HIV/AIDS (PLHIV) for all questionnaire items except for those listed under shame and blame. Positive attitudes towards PLHIV were observed to be greater among those with a better HIV/AIDS-related knowledge score. There was no significant association between the attitudes towards PLHIV and socio-demographic characteristics such as ethnicity and religion. There is a greater need of making attempts towards educating the public regarding HIV/AIDS to eliminate misconceptions prevalent in the society. Stigma-related attitudes are mainly due to shame and blame associated with the disease. As the attitudes towards PLHIV were more positive among those with a better HIV/AIDS-related knowledge score, targeted HIV/AIDS-related health education interventions maybe recommended in this regard.

Abstract
BACKGROUND The effects of socio-economic factors on suicide were gender-dependent. Japanese suicide mortality gender ratio (male: female) had gradually increased during the twentieth century. METHODS With the data covering 1947-2010 collected from Japanese official websites, we conducted non-parametric rank test, curve estimations, spearman ranking correlation and quantile regression in succession with Stata version 12.0. RESULTS The suicide mortality rate in male with a "U" shape had been always higher than that in female with a "J" shape. The male suicide mortality peaked around in 1955 (38.5 per 100,000 populations), dropped quickly afterwards until the 1970s; it increased in the 1980s with another peak in 2003 (33.2 per 100,000 populations). For female, an overall decreasing trend was seen with a peak during the 1950s (23.5 per 100,000 populations in 1958). It dropped gradually afterwards with small variations in 1970s and 80s, and was stabilized after 1995 (9.3 per 100,000 populations). The unemployment rate could be used as a single positive predictor of suicide mortality for men (p<0.01), while the total fertility rate (TFR) (p<0.01) and divorce rate (p<0.01) were significantly associated positively and negatively with women's suicide, respectively. LIMITATIONS The impact of mental disorders was not analyzed and age-specific analysis was not conducted. CONCLUSION The findings of these gender differences in, and the associated factors with, suicide in Japan, warranted further studies including delineation of the implications of differential economic pressure between genders, as well as child-rearing pressure and marriage satisfaction.

Abstract
This study aimed to explore the gender-based seasonal patterns of suicide in Japan between 2005 and 2012. With data from Japanese official reports, we carried out Prais–Winsten regression and Wilcoxon signed-rank test analysis with Stata 12.0 and SPSS 14.0. The suicide number was significantly higher in March, April, May, June, July, and October for both genders. The suicide number in men was markedly higher than that in women in every month. The suicide number in 2010 was lower than that in 2009 for men, while that in 2011 was higher than that in 2010 for women. The findings displayed that the nationwide television and publicity intervention campaigns might have positive effects on decreasing suicide of men while women suffered a post-earthquake increase. In terms of interventions, we should not only square up the seasonal patterns but also the gender differences in vulnerability.

Abstract
BACKGROUND This study aims to evaluate the length of time elapsed between reports of the same incidents related to avian flu and H1N1 outbreaks published by the WHO and ProMED-mail, the two major global health surveillance systems, before and after the amendment of the International Health Regulations in 2005 (IHR 2005) and to explore the association between country transparency and this timeliness gap. METHODS We recorded the initial release dates of each report related to avian flu or H1N1 listed on the WHO Disease Outbreak News site and the matching outbreak report from ProMED-mail, a non-governmental program for monitoring emerging diseases, from 2003 to the end of June 2009. The timeliness gap was calculated as the difference in days between the report release dates of the matching outbreaks in the WHO and ProMED-mail systems. Civil liberties scores were collected as indicators of the transparency of each country. The Human Development Index and data indicating the density of physicians and nurses were collected to reflect countries' development and health workforce statuses. Then, logistic regression was performed to determine the correlation between the timeliness gap and civil liberties, human development, and health workforce status, controlling for year. RESULTS The reporting timeliness gap for avian flu and H1N1 outbreaks significantly decreased after 2003. On average, reports were posted 4.09 (SD = 7.99) days earlier by ProMED-mail than by the WHO. Countries with partly free (OR = 5.77) and free civil liberties scores (OR = 10.57) had significantly higher likelihoods of longer timeliness gaps than non-free countries. Similarly, countries with very high human development status had significantly higher likelihoods of longer timeliness gaps than countries with middle or low human development status (OR = 5.30). However, no association between the timeliness gap and health workforce density was found. CONCLUSION The study found that the adoption of IHR 2005, which contributed to countries' awareness of the importance of timely reporting, had a significant impact in improving the reporting timeliness gap. In addition, the greater the civil liberties in a country (e.g., importance of freedom of the media), the longer the timeliness gap.

Abstract
OBJECTIVE To investigate comparative road user crash and fatality rates in Japan between 2000 and 2010 in the elderly and young. METHODS Data from the Japan Ministry of Health, Labor and Welfare Vital Statistics Database and the Institute for Traffic Accident Research and Data Analysis were used to calculate crash rates by age group, vehicle, and license category. RESULTS Fatal crash rates per 100,000 licensed drivers for 4-wheeled motor vehicle drivers decreased by 53, 56, and 42 percent among the 65-69, 70-74, and ≥75 age groups between 2000 and 2010, respectively, compared to 66 and 60 percent among the 16-19 and 20-24 age groups, respectively. Fatal crash rates per 100,000 licensed riders for 2-wheeled motor vehicles decreased by 64, 23, and 33 percent in the 65-69, 70-74, and ≥75 age groups, respectively. Similarly, fatal crash rates per million population among bicyclists and pedestrians decreased in all age groups but were highest in the elderly age group in all years; the annual fatal crash rate for elderly pedestrians was 3 to 10 times higher than that for younger pedestrians. CONCLUSIONS Despite the overall decrease in the elderly crash and fatal crash rates in all road use categories, elderly pedestrians are more susceptible to road traffic crashes and are more likely to be killed than younger persons. Further research may reduce this risk.

Abstract
AIM This study analyzed the trend of gender gaps in life expectancy (GGLE) in Japan between 1947 and 2010, and explored the correlations of GGLE with gender mortality ratio and social development indices. METHODS Using GGLE and social indices data collected from the official websites, we carried out trends analysis of GGLE by calculating segmented average growth rates for different periods. We explored the association between GGLE and all-cause mortality; and between GGLE and Human Development Index (HDI) while controlling for time trend, by computing the generalized additive models based on the software R (version 2.15). RESULTS Japan's GGLE increased in a fluctuating fashion. Across 53 years, the average growth rates varied widely: 0.14% (1947-1956), 1.43% (1956-1974), 1.06% (1974-2004) and -0.60% (2004-2010) (overall average 0.87%). The value of GGLE peaked to 7.00 years in 2004, and then has slowly declined (6.75 years in 2010). Age-adjusted all-cause gender mortality ratio had a statistically positive association with GGLE (P<0.01), whereas HDI was found to have no such association. CONCLUSION The increased trend of GGLE in Japan could be partly explained by increased disease-specific mortality ratios (male/female), especially those involving chronic bronchitis and emphysema, diseases of the liver, suicide and cancer. The recent decline of GGLE might imply that Japanese women have been catching up with the lifestyle of men, resulting in similar mortality patterns. This calls for gender-sensitive approaches to developing policies and programs that will help sustain healthy lifestyles to combat smoking and alcohol intake, and social support to prevent suicide.

Abstract
OBJECTIVES The primary objective of this study was to determine the level of knowledge, attitudes and practices (KAP) of rabies management and control of a sample population. The secondary objective was to compare the KAP with respect to rabies management and control between urban and rural areas and between pet and non-pet owners. METHODS This cross-sectional study was carried out by conducting face-to-face interviews using structured questionnaires among 1570 respondents from selected households in the Kandy District, Sri Landa. RESULTS Approximately 58% of the sample population was pet owners. Among all the respondents, there was a high level of awareness (90%) that dogs are the most common rabies reservoir, that the disease is fatal (79%), and that rabies can be prevented by vaccination (88%). Most of the subjects (96%) would seek treatment from a doctor or a hospital after being bitten by a dog. Although 76% of the respondents said that their pet dogs were vaccinated, only one-half were able to present a vaccination certificate upon request. The subjects from the urban areas would submit the head of an animal for rabies evaluation (69%) compared with those from the rural areas (57%). Pet owners (93%) are more aware that dog rabies vaccines are available from authorized offices than non-pet owners (87%). CONCLUSIONS The level of awareness of rabies and the level of receptiveness to rabies control measures are high. There is a difference in the attitudes and pet care practices relevant to rabies control between urban and rural areas. Pet owners tend to be more cooperative to rabies control activities. The attitudes and practices of the respondents may reflect the inaccessibility of facilities and the lack of services that would enable community participation in rabies control.

Abstract
To help formulate a local intervention for leptospirosis in Sri Lanka, we determined the serogroups of leptospiral species among 97 patients diagnosed with leptospirosis at the University of Peradeniya Teaching Hospital, Sri Lanka. Ninety-two point eight percent of the patients were men; nearly two-thirds were > or = 35 years old; the majority had secondary or higher education level, half were farmers or laborers; and 57.7% presented in the acute-phase of the illness. Twenty-five patients (25.8%) were confirmed to have leptospirosis by a positive laboratory method; 17 and 8 cases were confirmed with a positive test by quantitative MAT and nested PCR, respectively. Of the 17 MAT positive cases, infection occurred in a variety of serogroups, but the predominant groups were Sejroe and Tarassovi. Of the 8 nested PCR positive cases, 7 were seen among those with a MAT titer <200 and 1 occurred in a patient with a MAT titer > or = 200 but <400. Of the 8 PCR positive cases, 7 were infected with the leptospiral species L. interrogans. Approximately 26% of the clinically diagnosed patients were confirmed by the two laboratory methods. Laboratory positivity was based on the time of blood collection after the onset of fever. Further studies are warranted to refine the clinical diagnostic criteria and to develop more efficient and accurate diagnostic tests for leptospirosis in resource limited settings.

Abstract
BACKGROUND Life expectancy (LE) is a major marker of individual survival. It also serves as a guide to highlight both the progress and the gaps in total social and societal health. Comparative LE in concert with measures of gender-specific experience, indices of empowerment and societal happiness and development offer a comparative tool to examine trends and similarities of societal progress as seen through the lens of cross-national experience. METHODS To determine the gender gaps in LE (GGLE) trends, we performed a longitudinal analysis, covering a period of 49 years (1960-2008). To examine the association of GGLE with development indices, we used the 2007 GGLE data, the newest happiness data mostly drawn from 2006; the 2006 Human Development Index (HDI) data and the 2006 Gender Empowerment Measure (GEM) data. RESULTS It revealed that most of the Organization for Economic Co-operation and Development (OECD) countries had a GGLE trend that occurred in an inverted U-curve fashion. We divided them into three subgroups based on the peak years of respective GGLE. The earlier the peak year, the happier the countries, the higher the HDI and the smaller the current GGLE are. Association analysis indicates that Happiness, HDI and GEM are all negatively associated with GGLE. CONCLUSION This pattern suggests that GGLE undergoes three phases of growth, peak and stability and decline. Japan will soon be seeing its GGLE gradually shrinking in the foreseeable future. The continuing increases in Happiness, HDI and GEM are associated with a decrease in GGLE, which should be carefully taken into consideration.

Abstract
In Sri Lanka, leptospirosis is a notifiable disease. In addition to having a routine disease reporting system, Sri Lanka has implemented a hospital-based sentinel surveillance system since 2004. This report discusses the findings of a descriptive analysis of the sentinel surveillance data collected from 2005 to 2008. Of the 4,000 suspected leptospirosis cases, 46.9% and 26.8% were recorded from the Western and Sabaragamuwa provinces, respectively. Most of the individuals were male (83.5%), and approximately 45.6% were aged 30-49 years. Farmers accounted for 16.5%, and laborers for 16.1%; however, the occupation of nearly half (44.8%) of the study population was unknown. More than half (53.9%) of the individuals worked in paddy fields. Almost all had acute fever (98.8%), myalgia (92.9%), and headache (92.7%), but fewer had other related symptoms. Out of the 4,000 individuals, 2,496 (62.4%) underwent a laboratory test; however, the laboratory test results of only 1,445 (57.9%) and the microscopic agglutination results of 41 (2.8%) were available at the sentinel sites. Less than 2% of the reported individuals underwent prophylactic treatment. These findings will help enhance the ongoing efforts for controlling and preventing leptospirosis in Sri Lanka. Sentinel surveillance is a useful tool, but the data quality needs to be improved by supplementing the findings with adequate laboratory diagnosis data.

Abstract
HIV/AIDS is a major public health problem worldwide, especially in developing countries. The development of a safe and effective HIV vaccine is central to stopping the epidemic and would be a great public health tool. The AIDS Vaccine for Asia Network (AVAN) is a group of concerned investigators committed to assisting regional and global HIV vaccine efforts. AVAN's focus on improving the coordination and harmonization of research, ethical reviews, clinical trial capacity, regulatory frameworks, vaccine manufacturing, community participation, and government advocacy could help accelerate HIV vaccine efforts in the region. At a meeting in November 2010, researchers from various countries in Asia presented their progress in HIV vaccine research and development. Six working groups discussed the current status, gaps and methods to strengthen capacity and infrastructure in various areas related to AIDS vaccine research and development. These discussions led to the development of prioritized action plans for the next 5 years. This report describes the gaps and challenges HIV vaccine research faces in the region and recommends improvement and standardization of facilities, and coordination and harmonization of all activities related to AIDS vaccine research and development, including possible technology transfer when a vaccine becomes available.

Abstract
AIM This cross-sectional study examined the relationships of fear of falling and falls self-efficacy with higher-level competence among community-dwelling senior citizens in Japan. METHODS Of the 822 registered senior citizens, 731 (89%) community dwellers were requested to participate in the survey using a mailed self-accomplished questionnaire. Data from 648 respondents with duly accomplished questionnaires were analyzed using R(2) , the coefficient of determination, based on a multivariate regression analysis. RESULTS Fear of falling, low falls self-efficacy and higher-level functional disability were observed among respondents. Of the hypothesized relationships examined by sex, fear of falling was significantly associated with disability among male respondents and low falls self-efficacy among both sexes. Several confounding variables were strongly associated with competence. CONCLUSION While the data underscore the strategic importance of promoting higher-level competence among the senior citizens, there is much to suggest that their competence is likely to be maintained if their fear of falling and falls self-efficacy were modified. Programs must also consider a wide array of intervening factors.

Abstract
A cross-sectional study was undertaken to determine the current prevalence of leptospirosis and hantaviral infections, and the socio-demographic characteristics and risk factors of infected patients, in Kandy, Sri Lanka. This report discusses the serological evidence of hantavirus infections among 105 suspected leptospirosis patients, 8 of whom had hantavirus antibodies. Serotyping ELISA showed that these 8 patients had high optical density values for Thailand virus. Most of the sera showed that the focus reduction neutralization test titer against Thailand virus was higher than that against Seoul virus, thereby suggesting that the hantaviral antibodies found in Sri Lanka are different from Seoul virus but closely related to Thailand virus. These findings imply that the hantaviral infection found in Kandy, Sri Lanka appears to be due to a virus similar to Thailand virus. Epidemiological analysis revealed that the association between hantavirus infection and socio-demographic characteristics was not statistically significant.

Abstract
The HIV/AIDS pandemic continues to spread and an AIDS vaccine is urgently needed. Regional alliances and international collaborations can foster the development and evaluation of the next generation of AIDS vaccine candidates. The importance of coordinating and harmonizing efforts across regional alliances has become abundantly clear. We recently formed the AIDS Vaccine for Asia Network (AVAN) to help facilitate the development of a regional AIDS vaccine strategy that accelerates research and development of an AIDS vaccine through government advocacy, improved coordination, and harmonization of research; develops clinical trial and manufacturing capacity; supports ethical and regulatory frameworks; and ensures community participation.

Abstract
Background Pregnancy-induced hypertension (PIH) is a common cause of perinatal mortality. It is believed to result from the interaction of several factors, including those related to the blood coagulation system. We performed genotyping and subgroup analyses to determine if the 4G/5G genotypes of the plasminogen activator inhibitor-1 gene (PAI-1) play a role in the pathogenesis of PIH, and to evaluate possible interactions of the PAI-1 polymorphisms with those of the angiotensinogen gene (AGT) and the endothelial nitric oxide synthase gene (NOS3). Methods An association study of PAI-1 polymorphism, and subgroup analyses of common variants of AGT and NOS3, among 128 patients with PIH and 376 healthy pregnant controls. Results No significant differences were found between the cases and controls in the frequencies of allele 4G or the 4G/4G genotype. In subgroup analyses, after adjustment for multiple comparison, a significant association with the AGT TT genotype was found among women with the PAI-1 4G/4G genotype, and an association with the NOS3 GA+AA genotype was found among women with the 5G/5G or 4G/5G genotypes. Conclusions Our findings suggest that there are at least 2 pathways in the pathogenesis of severe PIH. However, with respect to early prediction and prevention of severe PIH, although the PAI-1 4G/4G genotype alone was not a risk factor for severe PIH, the fact that PAI-1 genotypes are associated with varying risks for severe PIH suggests that PAI-1 genotyping of pregnant women, in combination with other tests, may be useful in the development of individualized measures that may prevent severe PIH.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) prevalence is relatively lower in Sri Lanka than in other Asian countries; however, the number of HIV-infected persons has rapidly increased in recent years. METHODOLOGY A baseline study on HIV, acquired immunodeficiency virus (AIDS), and sexually transmitted infections (STI) knowledge, attitude, and practice was conducted at two construction sites in Sri Lanka from January to February 2007 to design an effective intervention strategy for the construction workers. RESULTS Among 611 respondents (mostly males, mean age 32.8 years), nearly two-thirds lived away from home. Knowledge was fairly good on AIDS prevention but poorer on STI than on HIV. Some misconceptions were also observed. A high percentage did not consider HIV/AIDS as their own personal issue, and over 50% respondents expressed discriminatory attitudes towards HIV positives. Condom access was limited due to social and cultural norms. Mobility was not significantly associated with practice of prevention of HIV and STI. CONCLUSION This study showed that the construction workers were not specially at higher risk of HIV at that time. In order to minimize the potential risk of infection, however, it would be effective to reduce stigma and discrimination among them through the prevention program, working together with community or religious leaders in the areas. More comprehensive assessment among other population groups would also be beneficial to identify their risk of infection.

Abstract
BACKGROUND Rabies remains endemic in Sri Lanka despite a strong government patronized anti-rabies campaign. Personal, cultural or religious beliefs have been thought to influence health practices that could render rabies prevalent in the country. METHODOLOGY The knowledge, attitudes, and beliefs of 580 household heads/members from Nuwara Eliya District, Sri Lanka, regarding rabies were explored through a structured questionnaire. An improvement/deterioration in their knowledge and practices after the use of information and education campaign (IEC) materials was assessed through a repeat exploration at an interval of four weeks. RESULTS Respondents showed inclination toward animal birth control (60%) rather than elimination methods (24%). There was disparity between pet owners enthusiasm to take pets for rabies inoculation (57%) and their ability to show dog vaccination cards (40%). Almost twice more pet owners than non-pet owners believed that it is their responsibility to control the population of roaming pet dogs (aOR=1.78; 95% CI: 1.14 to 2.76). The rabies leaflets were very effective in informing the people on how to deal with rabid animals, the earliest schedule for anti-rabies vaccine (ARV), and repeat vaccination. CONCLUSIONS Awareness and proper attitude toward rabies management and canine population control are adequate among the rural Sinhalese and Buddhist populations of Sri Lanka; however, their current health practices should be improved. The rabies KAP could be further enhanced through the use of IEC materials.

Abstract
The prevalence of obesity and its relationship to lifestyle habits was studied in Minami Furano Town, a small farming town in Hokkaido, Japan. All residents of Minami Furano Town over 18 years of age were given an anonymous, self-administered questionnaire in March, 2002. Logistic-regression analysis was performed separately for each gender with obesity as the dependent valuable, and lifestyle risk factors as explanatory variables. The prevalence of obesity (BMI > or = 25) was 30.2% in men and 29.2% in women. The risk factors for obesity included "smoking", "having no hobby", "low intake frequency of green vegetables", "high intake frequency of cooking oil" and eating "a large quantity at dinnertime" in men. For women the risk factors included "age", "stress", "drinking alcohol", "eating quickly", "low tooth brushing frequency" and "irregular health checks". Nearly one third of the adults in this town were obese when assessed using the Japanese criteria of BMI > or = 25. Few women were employed full-time and they had limited opportunity for periodic health checks. Improved community-based nutrition activities are needed for women.

Abstract
According to the Joint UN Program on AIDS (UNAIDS), an estimated 4.9 million adults and children are living with HIV in Asia and the Pacific. Refinement and development of existing and new prevention and treatment technologies--including safe, effective, and accessible AIDS vaccines--are urgent public health priorities. The Asian region faces several challenges for AIDS vaccine development. There are multiple genetic variants of HIV-1 driving the epidemic in the region and too few vaccine candidates in the pipeline targeting those subtypes. Low HIV incidence throughout the region means that trial sites must recruit larger numbers of volunteers and shift their focus to higher-risk populations where incidence is higher. Also, the cultural, economic, and political diversity of the region may render collaboration very complex, but also beneficial at a regional level. Recognizing that collaborating as a region could foster and accelerate AIDS vaccine development, participants at the Sapporo International Consultation recommended that an AIDS Vaccine Asian Network (AVAN) be created to facilitate interactions between donors and funding opportunities, increase regional clinical trial and production capacity, support region-specific advocacy and communication strategies, contribute to the Global HIV Vaccine Enterprise Scientific Plan, prepare a regional approach for future vaccine deployment, and develop a regional platform for clinical trials including harmonized legal, regulatory, and ethical frameworks.

Abstract
In the community-based cross-sectional study, we investigated patterns of lifestyle activities among older people and examined the association between specific types of lifestyle activity and depressed mood status. The participants were 656 men and women aged 65 or older in 2004 who lived in a rural town in Japan, neither institutionalized nor hospitalized and who did not have symptoms of dementia. We found that less interaction with neighbors, society and friends was highly associated with depressed mood for men. Additionally, although they were physically active in gardening/farming, it did not necessarily mean that they were mentally healthy if they did not have close ties with friends, family and children/grandchildren. For women, it seemed important to engage in several types of activities relating to society, leisure and children/grandchildren to be in less depressed mood. Even if they were socially inactive, if they had frequent contact with family and children/grandchildren or going out for pleasure they were less likely to be depressed. Distinguishing gender differences in lifestyle activity patterns and the association of activities with depressed mood will help to guide the development of depression intervention programs.

Abstract
Since 1957 Japan has successfully eradicated human and animal rabies through registration, confinement and compulsory vaccination of family dogs, and elimination of stray dogs. However, in November 2006, two cases of human rabies infections were reported in the country. These patients were bitten by dogs during travel in the Philippines, and did not receive pre- and post-exposure prophylaxes. With the mounting numbers of Japanese travelers every year, the risk of infection increases especially to those who visit regions where the disease is endemic. In this paper, we shall discuss the two recent human deaths from rabies, review the current situation and control measures in Japan and surrounding countries where the disease is prevalent, summarize precautionary measures for travelers, and suggest public health strategies to prevent the re-introduction of rabies in the country.

Abstract
A novel severe acute respiratory syndrome‐associated coronavirus (SARS‐CoV) has been discovered. The detection of both antigens and antibodies in SARS‐CoV from human specimens with suspected SARS plays an important role in preventing infection. We developed a novel rapid immunochromatographic test (RICT) based on the sandwich format enzyme immunoassay (EIA) with an all‐in‐one device for detecting the native nucleocapsid antigen (N‐Ag) of SARS‐CoV using monoclonal antibodies (MoAbs), which we produced by immunizing recombinant N‐Ag to mice. RICT is a qualitative assay for respiratory aspirates and serum specimens. With this assay, a positive result can be judged subjectively by the appearance of a blue line on the device 15 min after the sample is applied. RICT with several pairs of MoAbs showed a high sensitivity for the detection of recombinant N‐Ag as well as viral N‐Ag of SARS‐CoV. rSN122 and rSN21‐2 were the best MoAbs for immobilized antibody and enzyme labeling, respectively. With regard to analytical sensitivity, RICT detected N‐Ag at 31 pg/mL for recombinant N‐Ag, and at 1.99×102 TCID50/mL for SARS‐CoV. The specificity of RICT was 100% when 150 human sera and 50 nasopharyngeal aspirates (NSPs) were used. RICT based on an EIA using the rSN122/rSN21‐2 pair is a sensitive, specific, and reliable rapid assay for detecting N‐Ag in SARS‐CoV treated with either heat or Triton X‐100. J. Clin. Lab.

Abstract
Using the data from the community-based longitudinal study of the elderly persons aged 65 or older, this study examined relationships between the occurrence of falls varied by their activity level and subsequent functional decline over time. Of the 705 respondents at baseline, 662 and 632 subjects were assessed at first and second follow-ups. Falling and homebound status at baseline and health function (self-rated general health, activities of daily living (ADLs), instrumental activities of daily living (IADLs), intellectual activity, and social role) at baseline and follow-ups were assessed, and changes in each health function were compared among four groups defined by baseline falling/homebound status. Baseline falling/homebound status was significantly associated with subsequent decline in ADLs over 1 year, and in ADLs, IADLs, intellectual activity, and social role over 2 years. Being homebound might act as a stronger risk factor for ADLs disabilities rather than the occurrence of falls. Moreover, the homebound elderly with no experience of falls was at the greatest risk of the decline of social role. We consider that prevention program and home-based care for homebound elderly should be provided in the community.

Abstract
OBJECTIVE To examine the nonlinear association of higher-level functional capacity with the incidence of falls. DESIGN We analyzed the cross-sectional data of Minamifurano-town Aging Study. Seven hundred forty-three noninstitutionalized older persons aged 65 yrs or older were mailed a self-administered questionnaire in June 2002 in which they were asked the incidence of falls in the past year and their higher-level functional capacity according to the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence. The association of higher-level functional capacity with the incidence of falls was examined using linear, polynomial, and nonparametric logistic regression models. RESULTS Under the assumption of a nonlinear function, the quadratic function and the smoothing function provided a significant improvement of the fit compared with the linear model in women but not men. CONCLUSION We have proposed the use of nonlinear model in estimating the incidence of falls with respect to the total score of the TMIG index of competence. The association of varying total score with the incidence of falls in women diverged from the linearity assumption. The gender-based difference in the association of higher-level functional capacity with the incidence of falls might be related to societal role or activity-related aspects.

Abstract
BACKGROUND/AIMS Living donor liver transplantation is becoming increasingly important in the Western world, but the economic issues remain controversial. We conducted a cost-utility analysis to evaluate whether living donor liver transplantation is cost-effective. METHODOLOGY Cost and utility analyses were performed in a longitudinal survey of a single center in Sapporo, Japan. Medical costs were derived from 11 patients who underwent living donor liver transplantation. Health utility was measured in quality-adjusted life year. Data for health utility scores were derived from 19 patients who underwent living donor liver transplantation. RESULTS Median medical cost was U.S. dollars 154,626 from the first day of preoperative evaluation to 24 months post-transplantation. Cumulative quality-adjusted life years were 1.60 at 24 months after transplantation. Medical cost per quality-adjusted life year decreased progressively, leading to medical cost of U.S. dollars 605,131 per quality-adjusted life year at 3 months to U.S. dollars 94,169 at 24 months after transplantation. The results were sensitive to medical cost. CONCLUSIONS Follow-up survey identified progressive increases in the cost-effectiveness of living donor liver transplantation for patients with end-stage liver disease. Living donor liver transplantation appears to represent a cost-effective medical technology.

Abstract
OBJECTIVE To examine the relative importance of risk factors associated with depressive symptoms and gender differences in exposure to the risk factors among the elderly persons living in the community. METHODS The data came from the Minamifurano-town Aging Study, a community-based sample of non-institutionalized elderly persons aged 65 years or older. Of the 731 eligible subjects, 665 were assessed for four domains of the potential risk factors (demographic characteristics, health and disability, stress, and social networks) and depressive symptoms according to the 30-item Geriatric Depression Scale (GDS). RESULTS The mean overall GDS-score was 10.9 (SD 6.2), 10.2 (SD 6.0) in men and 11.6 (SD 6.4) in women. The stress domain in men and the health and disability domain in women contributed most to the explanation of the variation in the GDS-score. CONCLUSION 'Stress' for men and 'health and disability status' for women were important factors associated with depressive symptoms. Future studies should determine whether modification of these factors may prevent depression among the elderly persons living in the community.

Abstract
This paper discusses the history of emerging infectious diseases, risk communication and perception, and the Supercourse lectures as means to strengthen the concepts and definition of risk management and global governance of zoonosis. The paper begins by outlining some of the key themes and issues in infectious diseases, highlighting the way which historical analysis challenges ideas of the 'newness' of some of these developments. It then discusses the role of risk communication to public accountability. The bulk of the paper presents an overview of developments of the Internet-based learning system through the Supercourse lectures that may prove to be a strong arm for the promotion of the latest medical information particularly to developing countries.

Abstract
Since the advent of bovine spongiform encephalopathy (BSE) in the United Kingdom in 1986, new BSE cases have recently become rare. However, in Japan and the United States, positive cases have started to be seen recently. The rise in BSE cases paved the way for the human form of this disease, the variant Creutzfeldt-Jakob disease (vCJD). The observed trends in the UK may be attributed to effective implementation of public health policies coupled with increased vigilance through advancement in science and technology, or they may well be a reflection of the natural disease progression. We aim to discuss the BSE chronology of events, and compare examination methods, costs and cost-efficiency, management, and public policies of Japan, Europe, and the USA.

Abstract
To assess the association between the egogram and hypertension in pregnancy (HP), a case-control study was carried out. Seventy-one HP cases, primiparous aged 20 to 34 years, and 109 controls, were enrolled among pregnant women who visited our hospitals for obstetrical care. Data from a self-administered questionnaire containing a Self Grow-Up Egogram (SGE) were subjected to univariate and multivariate analyses with prepregnancy body mass index (BMI) and angiotensinogen (AGT) genotype. The mean +/- standard error of total scores for the critical parent (CP) scale were 9.7 +/- 0.5 for cases and 8.3 +/- 0.3 for controls, those for the nurturing parent (NP) scale were 13.6 +/- 0.4 for cases and 13.4 +/- 0.3 for controls, those for the adult (A) scale were 11.3 +/- 0.5 for cases and 10.9 +/- 0.3 for controls, those for the free child (FC) scale were 12.3 +/- 0.3 for cases and 13.8 +/- 0.3 for controls, and those for the adapted child (AC) scale were 10.2 +/- 0.4 for cases and 8.5 +/- 0.4 for controls. A low FC scale score (FC < or = 10) and a high AC scale score (AC > 10) were significantly associated with HP ( p < 0.05; p < 0.01, respectively). In the multivariate analysis, FC < or = 10, AC > 10, prepregnancy BMI > or = 24, and homozygosity of the T235 allele genotype of the AGT gene were detected as the potent independent risk factors for HP. The odds ratios were 2.2, 2.8, 4.0, and 2.5, respectively. The present results suggest that a low FC score and a high AC score may be potent, independent risk factors for HP.

Abstract
To clarify whether the homozygous deletion (DD) genotype of angiotensin-converting enzyme gene ( ACE) is a genetic risk factor for preeclampsia in Japanese women, we performed ACE genotyping in patients with preeclampsia and healthy pregnant women, and analyzed the relationship between preeclampsia and ACE genotype, taking into account some well-known contributing factors for preeclampsia, such as primiparity, positive family history of hypertension, prepregnancy body mass index < 24, and heterozygosity and homozygosity of T235 (MT+TT) genotypes of the angiotensinogen ( AGT) gene. Among all of the subjects, the frequency of the DD genotype was not different between patients with preeclampsia and controls (16% and 12%, respectively). Regarding primiparity, prepregnancy body mass index < 24, and MT+TT genotypes of AGT, no significant differences in the frequency of the DD genotype of ACE were found between patients with preeclampsia and controls, although in a subgroup positive for family history of hypertension, the frequency of the DD genotype tended to be higher in patients with preeclampsia (25%) than in controls (8%; p = 0.061). Carrying the DD genotype may have some influence on the pathogenesis of preeclampsia, perhaps through effects on placental hypoxia or the interaction of hypertensive disease and atherosclerosis, although this influence may not be strong. Additional studies using a larger number of patients and analyses that include other genetic and environmental factors will be necessary to confirm these results.

Abstract
Dementia is one of the common causes that lead to dependence of senior citizens in daily living. Clarifying the features of the elderly with dementia is instrumental in planning for their effective care and support in a community, and for attempts at prevention. Our purpose was to investigate the impact of sociodemographic factors among the elderly with the presumptive diagnosis of dementia. We carried out a survey annually from 1998 to 2002 in a dynamic cohort of community-dwelling individuals aged 65 years or older. Of the 945 subjects, 782 were eligible for study because at the first interview they were asymptomatic for dementia and not institutionalized. We found no significant difference in a 5-year average incidence rate between genders. However, the risk of developing dementia increased with age. The study population was categorized into three groups of living arrangement: those living with spouse and others, those living alone, and those living with persons other than the spouse. The incidence rate of dementia among the elderly who lived with spouse and others was significantly lower than for those among the other groups. This was also notable in the subjects without a history of stroke, even after adjustment for age and gender. This result indicates that living with spouse might have an important benefit in reducing the risk of developing dementia, although this effect would vary with the type of dementing disease. We suggest that preventive measures in clinical and community care of the elderly should focus on interactive social conditions such as living environments.

Abstract
OBJECTIVE A survey was carried out to assess smoking among students, and administration and teaching staff in Hokkaido University School of Medicine in 2003. METHODS We conducted a questionnaire survey on smoking of undergraduates, graduate students, administration personnel and teaching staff in Hokkaido University School of Medicine in February 2003. The majority of question items were targeted for all subjects while some items were addressed separately to smokers, ex-smokers and non-smokers. RESULTS AND DISCUSSION The survey showed that 1) the smoking rate of the study subjects is lower than that of physicians, in general; 2) dependence on cigarettes among smokers is relatively low; and 3) 80% of the ex-smokers are in the maintenance stage, while 20% are in the action stage. Furthermore, 1) there was a tendency for smokers and non-smokers to be concerned with the health effects of passive smoking than that of active smoking; 2) smokers tended to ignore the unpleasant smell of cigarettes as compared with ex-smokers and non-smokers; 3) although the three groups acknowledged the health affects of smoking, they are not proactive in the promotion of anti-smoking; and 4) everyone is generally concerned with the smell of cigarettes but tended to accept it in the school of medicine. CONCLUSIONS It is an important issue how smokers in the interested stage can move to the anti-smoking stage, and how those in the action stage shift to the maintenance stage. We have carried out anti-smoking events and campaigns on the campus based on the results of the survey and further plan to formulate a strategy for anti-smoking on the campus. The specific activities will be undertaken and the results evaluated in future.

Abstract
The objectives of this study were to understand transition patterns and mechanisms of functional status, and to estimate active life expectancy (ALE) among senior citizens in a small town in Japan. With data drawn from surveys conducted annually from 1998 to 2002 (n=638 at baseline), prevalence and incidence of functional disability in activities of daily living (ADL) and instrumental activities of daily living (IADL) were described and compared between the sexes. Then relationships between potential predictors and functional decline through a 4-year follow-up were examined using logistic regression. Finally, active and disabled life expectancy was estimated by Katz's method. At baseline, 9 and 12% of subjects were dependent in performing ADL and IADL, respectively. Prevalence and incidence rates increased with age. The risk of mortality increased by 2.2-5.0-fold when the subject was functionally dependent at the previous year. Advanced age, difficulty in walking and poor interest were shown to be significant predictors of loss of independence in ADL. Mean durations with disability in ADL and IADL among women were longer than among men by around 1 year. Population-specific preventive care programs considering physical, cognitive and social aspects are needed not only to maximize ALE but also to improve quality of life during survival period with disability especially in old women.

Abstract
We focused on the epidemiology of alveolar echinococcosis especially in Japan and discussed control measures to prevent an epidemic. No effective control measures against alveolar echinococcosis have been identified thus far because it is difficult to fully understand the ecology of the parasite and its hosts, i.e. the precise infection route to humans. In Hokkaido, Japan, infection rates among red foxes have recently risen even in low endemic districts. Infection seems to be spreading not only among wild foxes but also among domestic dogs. Despite only sporadic reports of human cases in Japan, we predict that the incidence of alveolar echinococcosis will increase in the near future if no effective preventive measures are put in place. An Echinococcus multilocularis epidemic would have the potential to affect the economy of Hokkaido, due to its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are, therefore, urgently required prior to large outbreaks, based on understanding of the ecosystem around E. multilocularis.

Our goals are to review the literature on the definition and epidemiology of fecal incontinence (FI), the risk factors involved, available treatment options, and measurement of the quality of life (QOL) of patients with this condition. Articles included for review were searched following the guidelines set by Cochrane Reviewers' Handbook. FI was defined variously depending upon the duration, type, and amount of leakage. About 17 published papers were reviewed on the prevalence of FI that ranged from 1.4% to 50%. Potential risk factors included perianal injury/surgery, and fair/poor general health. QOL assessment using various grading scales provided an objective method of evaluating patients before and after treatment. Management included medical, physiotherapy, and surgical options. Through the range of various references, a clear definition of FI should be specified, which reflects its epidemiology in the various studies. These differences in definition would significantly affect its prevalence. Many risk factors have been sited but further epidemiological studies are necessary to elucidate FI. Understanding the etiology of the disease is an important initial step to provide adequate treatment of FI. QOL assessment provides objective and subjective method in the analysis of effectiveness of therapy.

Abstract
OBJECTIVE To clarify the health status and lifestyle issues of homeless people in Sapporo city, voluntary "health consultations and medical examinations" were carried out near an emergency kitchen. METHODS The voluntary activities were held in a park near the shelter tents of homeless people seven times from December 1999 to December 2000. The homeless people who consulted us, medical doctors, were asked detailed questions about past history, present illness, subjective symptoms, lifestyles and so on, and were examined for their blood pressure and urinary parameter. RESULTS A total of 60 homeless people, including 59 men and 1 woman, were consulted and examined, Fifty-seven percent of them were 50 years old of older, and 30% had been homeless for less than half a year. Forty percent had some dental problems, 28% suffered neck stiffness, and 27% back pain. The medical examination found 53% of them to be hypertensive and 26% to be diabetic. Twenty-five percent had meals only once a day, 55% had meat or fish in their diet not more than twice a week and 57% had vegetables in their diet not more than twice a week. Forty-two percent slept not more than 5 hours a day, 13% often drank alcohol in the daytime, and 83% were smokers. CONCLUSION The present results suggest that lifestyle-related chronic diseases are more significant problems among homeless people in Sapporo city than common infectious diseases such as tuberculosis or dysentery, probably because it is colder and therefore there are fewer homeless people in Sapporo city than in other major cities in Japan such as Tokyo and Osaka. Further studies of the homeless people living in such a cold environment are warranted to develop better health policies for them in the context of their social and economical determinants. In addition, it is important to establish a more reliable registration system for these people in order to plan and provide a comprehensive social and health support network as needed.
