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.

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.

Abstract
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.
