Abstract
We performed serial Health Care Utilization and Attitudes Surveys (HUASs) among caretakers of children ages 0–59 months randomly selected from demographically defined populations participating in the Global Enteric Multicenter Study (GEMS), a case-control study of moderate-to-severe diarrhea (MSD) in seven developing countries. The surveys aimed to estimate the proportion of children with MSD who would present to sentinel health centers (SHCs) where GEMS case recruitment would occur and provide a basis for adjusting disease incidence rates to include cases not seen at the SHCs. The proportion of children at each site reported to have had an incident episode of MSD during the 7 days preceding the survey ranged from 0.7% to 4.4% for infants (0–11 months of age), from 0.4% to 4.7% for toddlers (12–23 months of age), and from 0.3% to 2.4% for preschoolers (24–59 months of age). The proportion of MSD episodes at each site taken to an SHC within 7 days of diarrhea onset was 15–56%, 17–64%, and 7–33% in the three age strata, respectively. High cost of care and insufficient knowledge about danger signs were associated with lack of any care-seeking outside the home. Most children were not offered recommended fluids and continuing feeds at home. We have shown the utility of serial HUASs as a tool for optimizing operational and methodological issues related to the performance of a large case-control study and deriving population-based incidence rates of MSD. Moreover, the surveys suggest key targets for educational interventions that might improve the outcome of diarrheal diseases in low-resource settings.

Abstract
OBJECTIVES To compare the prevalence and correlates of cigarette smoking among East Asian college students. METHODS Data were collected from college students (N=16,558) in China, Hong Kong, Malaysia, Singapore, South Korea, and Taiwan (response rate: 78%). RESULTS Religion was independently associated with college students' smoking in China (adjusted odds ratio [AOR] = 1.82) and South Korea (AOR = 0.80). Being a heavy drinker and having a higher exposure to secondhand smoke were associated with higher smoking rates (Ps < .001). CONCLUSIONS The East Asian economies show a varied prevalence of college smoking but a similar pattern of relationship with its correlates.

Abstract
Because type 2 diabetes (T2D) is highly familial, there has been a concentrated effort to uncover the genetic basis of T2D worldwide over the last decade. In East Asians, T2D is experiencing a rapidly rising prevalence that is characterized by a relatively lower body mass index, as compared with that in Europeans. To date, at least 15 convincing T2D loci have been identified from large-scale genome-wide association studies and meta-analyses in East Asians. Many of these are likely responsible for pancreatic β cell function, as indicated in studies from Europeans. Many T2D loci have been replicated across the ethnic groups. There are, however, substantial interethnic differences in frequency and effect size of these risk alleles. Despite accumulating genetic information on T2D, there are still limitations in our ability to explain the rapidly rising prevalence and lean phenotype of disease observed in East Asians, suggesting that more extensive work using diverse research strategies is needed in the future.

Abstract
Although the history of the tick-borne encephalitis in Urals dates back to 75 years ago, the problem of the spread and evolution of the tick-borne encephalitis virus (TBEV) largely remains terra incognita. Any research in this area is of great basic and practical importance. A few years ago, a hypothesis about the change of the TBEV genotype in the Sverdlovsk region in the 50-60-year period was put forward. In other words, replacement of the Far-Eastern genotype by Siberian genotype was suggested. The goal of this work was to discuss this hypothesis and the fallacy of this view. Recent large-scale data show the long history of the formation of Siberian TBEV virus population in the Middle Urals, as well as a foreign nature of Far-Eastern genotype through their introduction in the past. The concept of the decisive role of anthropogenic factor in the spread of TBEV in the Urals is discussed as an alternative to the hypothesis of the genotype change.

Abstract
Social epidemiology is the field of study that attempts to understand the social determinants of health and the dynamics between societal settings and health. In the past 3 decades, large-scale studies in the West have accumulated a range of measures and methodologies to pursue this goal. We would like to suggest that there may be conceptual gaps in the science if Western research models are applied uncritically in East Asian studies of socioeconomic, gender, and ethnic inequalities in health. On one hand, there are common concerns, including population aging and gendered labor market participation. Further, international comparison must be built on shared concepts such as socioeconomic stratification in market economies. On the other hand, some aspects of health, such as common mental disorders, may have culturally specific manifestations that require development of perspectives (and perhaps novel measures) in order to reveal Eastern specifics. Exploring and debating commonalities and differences in the determinants of health in Oriental and Occidental cultures could offer fresh inspiration and insight for the next phase of social epidemiology in both regions.

Abstract
PURPOSE The aim of this study is to systematically review the published literature from East Asia on the clinical, pathological, and epidemiological characteristics of primary clavicle tumor and tumorous lesions. METHODS A computerized search based on keywords "clavicle," "tumor," and "tumorous lesion" (both in Chinese and in English) was performed on literature published from 1980 to 2011 in East Asian countries, including China, Japan, South Korea, North Korea, and Mongolia. An analysis was carried out with unified inclusion and exclusion criteria. RESULTS Two hundred and six cases were identified. The age of onset ranged from 1.5 to 70, with an average age of 29.4, and a male/female ratio of 1.53:1. Lesion locations included 28.9% in medial third, 18.8% in the middle third, and 33.6% in the lateral third of the clavicle. Another 7.4% involved both the medial and middle thirds, 7.4% involved both the middle and lateral thirds, and 4.0% involved the entire length of the clavicle. Major pathological types included 18.5% eosinophilic granuloma, 10.2% plasmocytoma, 7.8% Ewing sarcoma, 8.7% osteosarcoma, 8.7% osteochondroma, and 5.3% chondrosarcoma. The age of onset was found to be strongly correlated with the benign/ malignant ratio. Clavicle malignancy was rarely found in patients younger than 10 years, while the incidence of malignancy greatly increased among patients over 40 years old. Total or subtotal claviculectomy was the most common treatment in cases for which treatment information was available. Of these, 40.8% of patients received reconstruction with allograft or autograft. CONCLUSIONS Clavicle tumors and tumorous lesions in East Asia had an inclined occurrence in respect to age and gender. The most common tumors were eosinophilic granuloma and tumors derived from the bone marrow hematopoietic system. Age of onset was found to be a risk factor for malignancy. These characteristics may be related to the special tissue structures and mode of development in the clavicle as well as to the genetic traits of the typical Mongoloids in East Asia.

Abstract
Background Influenza causes yearly seasonal epidemics and periodic pandemics. Global systems have been established to monitor the evolution and impact of influenza viruses, yet regional analysis of surveillance findings has been limited. This study describes epidemiological and virological characteristics of influenza during 2006–2010 in the World Health Organization's Western Pacific Region. Methodology/Principal Findings Influenza-like illness (ILI) and influenza virus data were obtained from the 14 countries with National Influenza Centres. Data were obtained directly from countries and from FluNet, the web-based tool of the Global Influenza Surveillance and Response System. National influenza surveillance and participation in the global system increased over the five years. Peaks in ILI reporting appeared to be coincident with the proportion of influenza positive specimens. Temporal patterns of ILI activity and the proportion of influenza positive specimens were clearly observed in temperate countries: Mongolia, Japan and the Republic of Korea in the northern hemisphere, and Australia, New Zealand, Fiji and New Caledonia (France) in the southern hemisphere. Two annual peaks in activity were observed in China from 2006 through the first quarter of 2009. A temporal pattern was less evident in tropical countries, where influenza activity was observed year-round. Influenza A viruses accounted for the majority of viruses reported between 2006 and 2009, but an equal proportion of influenza A and influenza B viruses was detected in 2010. Conclusions/Significance Despite differences in surveillance methods and intensity, commonalities in ILI and influenza virus circulation patterns were identified. Patterns suggest that influenza circulation may be dependent on a multitude of factors including seasonality and population movement. Dominant strains in Southeast Asian countries were later detected in other countries. Thus, timely reporting and regional sharing of information about influenza may serve as an early warning, and may assist countries to anticipate the potential severity and burden associated with incoming strains.

Abstract
Myopia has emerged as a major health issue in east Asia, because of its increasingly high prevalence in the past few decades (now 80-90% in school-leavers), and because of the sight-threatening pathologies associated with high myopia, which now affects 10-20% of those completing secondary schooling in this part of the world. Similar, but less marked, changes are occurring in other parts of the world. The higher prevalence of myopia in east Asian cities seems to be associated with increasing educational pressures, combined with life-style changes, which have reduced the time children spend outside. There are no reported major genes for school myopia, although there are several genes associated with high myopia. Any genetic contribution to ethnic differences may be small. However, to what extent many genes of small effect and gene-environment interactions contribute to variations in school myopia within populations remains to be established. There are promising optical and pharmacological interventions for preventing the development of myopia or slowing its progression, which require further validation, and promising vision-sparing treatments for pathological myopia.

Abstract
Multi-year literature data as well as materials of the Reference centre of monitoring of natural foci infections of Irkutsk Research Institute of Plague Control of Siberia and the Far East regarding epidemiology, epizootology and laboratory diagnostics of leptospiroses in Siberia and the Far East are analyzed and summarized in the review. Situation on leptospiroses in the region has changed significantly. In 50 - 70s of the 20th century diseases were registered ubiquitously in the form of outbreaks, group and single cases. Currently a low level of sporadic morbidity is noted in separate subjects of the Russian Federation. The contemporary state of the problem remains insufficiently clear, this demands the expansion of studies, creation of modern databases, as well as introduction into the practice of highly sensitive methods of express diagnostics in a complex with bacteriologic and serologic methods.

Abstract
AIM The Vein Consult Program is an international, observational, prospective survey aiming to collect global epidemiological data on chronic venous disorders (CVD) based on the CEAP classification, and to identify CVD management worldwide. The survey was organized within the framework of ordinary consultations, with general practitioners (GPs) properly trained on the use of the CEAP classification. METHODS Screening for CVD was to be performed by enrolling in the survey all consecutive outpatients >18 years whatever the reason for consultation, to record patient's data and classify them according to the CEAP, from the stage C0s to C6. The program enrolled 6232 GPs 91545 subjects were analysed. Their mean age was 50.6±16.9 years, younger patients being in the Middle East and older ones in Europe, and the proportion of women was higher than that of men. RESULTS The worldwide prevalence of CVD was 83.6%: 63.9% of the subjects ranging C1 to C6, and 19.7% being C0s subjects. C0s patients were more frequently men whatever the age and the geographical zone. C1-C3 appeared to be more frequent among women whatever the country but the rate of severe stages (C4-C6) did not differ between men and women. GPs consider CVD subjects as patients eligible to specialist referral beginning from C2 but some geographical disparities were observed. CONCLUSION The VCP survey provides reliable results on CVD global epidemiology and shows that CVD affects a significant part of the populations worldwide, underlining the importance of adequate screening for CVD and training of both GPs and specialist physicians.

Abstract
Many bacterial pathogens inject into host cells effector proteins that are substrates for host tyrosine kinases such as Src and Abl family kinases. Phosphorylated effectors eventually subvert host cell signaling, aiding disease development. In the case of the gastric pathogen Helicobacter pylori, which is a major risk factor for the development of gastric cancer, the only known effector protein injected into host cells is the oncoprotein CagA. Here, we followed the hierarchic tyrosine phosphorylation of H. pylori CagA as a model system to study early effector phosphorylation processes. Translocated CagA is phosphorylated on Glu-Pro-Ile-Tyr-Ala (EPIYA) motifs EPIYA-A, EPIYA-B, and EPIYA-C in Western strains of H. pylori and EPIYA-A, EPIYA-B, and EPIYA-D in East Asian strains. We found that c-Src only phosphorylated EPIYA-C and EPIYA-D, whereas c-Abl phosphorylated EPIYA-A, EPIYA-B, EPIYA-C, and EPIYA-D. Further analysis revealed that CagA molecules were phosphorylated on 1 or 2 EPIYA motifs, but never simultaneously on 3 motifs. Furthermore, none of the phosphorylated EPIYA motifs alone was sufficient for inducing AGS cell scattering and elongation. The preferred combination of phosphorylated EPIYA motifs in Western strains was EPIYA-A and EPIYA-C, either across 2 CagA molecules or simultaneously on 1. Our study thus identifies a tightly regulated hierarchic phosphorylation model for CagA starting at EPIYA-C/D, followed by phosphorylation of EPIYA-A or EPIYA-B. These results provide insight for clinical H. pylori typing and clarify the role of phosphorylated bacterial effector proteins in pathogenesis.

Abstract
This study explored the associations between the perpetration of partner violence and two types of face orientation-protective and acquisitive-in Chinese societies. Data from a convenience sample of 3,388 university students from Hong Kong, Shanghai, and Beijing were analyzed. The participants completed the Protective and Acquisitive Face Orientation (PAFO) Scale Short Form and the Revised Conflict Tactics Scale (CTS2) to measure their face orientations and experience of perpetrating violence against their dating partner. Acquisitive face orientation (AFO) was positively associated with the self-reported perpetration of physical and psychological partner violence. No significant associations were found between protective face orientation (PFO) and partner violence perpetration. Gender differences were found across all types of dating violence. City of residence, age, and SES were also associated with partner violence in specific ways. The findings gave insights on the possible mechanisms between partner violence and the concept of face to be explored in future research.

Abstract
Genetic factors play an important role in the etiology of both sporadic and familial breast cancer. We aimed to discover novel genetic susceptibility loci for breast cancer. We conducted a four-stage genome-wide association study (GWAS) in 19,091 cases and 20,606 controls of East-Asian descent including Chinese, Korean, and Japanese women. After analyzing 690,947 SNPs in 2,918 cases and 2,324 controls, we evaluated 5,365 SNPs for replication in 3,972 cases and 3,852 controls. Ninety-four SNPs were further evaluated in 5,203 cases and 5,138 controls, and finally the top 22 SNPs were investigated in up to 17,423 additional subjects (7,489 cases and 9,934 controls). SNP rs9485372, near the TGF-β activated kinase (TAB2) gene in chromosome 6q25.1, showed a consistent association with breast cancer risk across all four stages, with a P-value of 3.8×10−12 in the combined analysis of all samples. Adjusted odds ratios (95% confidence intervals) were 0.89 (0.85–0.94) and 0.80 (0.75–0.86) for the A/G and A/A genotypes, respectively, compared with the genotype G/G. SNP rs9383951 (P = 1.9×10−6 from the combined analysis of all samples), located in intron 5 of the ESR1 gene, and SNP rs7107217 (P = 4.6×10−7), located at 11q24.3, also showed a consistent association in each of the four stages. This study provides strong evidence for a novel breast cancer susceptibility locus represented by rs9485372, near the TAB2 gene (6q25.1), and identifies two possible susceptibility loci located in the ESR1 gene and 11q24.3, respectively. Breast cancer is one of the most common malignancies among women worldwide. Genetic factors play an important role in the etiology of breast cancer. To identify common genetic susceptibility alleles for breast cancer, we performed a four-stage genome-wide association study in 19,091 cases and 20,606 controls among East-Asian women. Single nucleotide polymorphism (SNP) rs9485372, near the TGF-beta activated kinase 1 (TAB2) gene at chromosome 6q25.1, was associated with breast cancer risk (P = 3.8×10−12). SNPs rs9383951, located in intron 5 of the estrogen receptor 1 (ESR1) gene, and rs7107217, located at 11q24.3, were also consistently associated with breast cancer risk in all four stages with a combined P of 1.9×10−6 and 4.6×10−7, respectively. This study provides strong evidence for a novel breast cancer susceptibility locus represented by rs9485372, near the TAB2 gene (6q25.1), and identifies two possible susceptibility loci located in the ESR1 gene and 11q24.3, respectively.

Abstract
BACKGROUND Observed co-morbidity among the mood and anxiety disorders has led to the development of increasingly sophisticated dimensional models to represent the common and unique features of these disorders. Patients often present to primary care settings with a complex mixture of anxiety, depression and somatic symptoms. However, relatively little is known about how somatic symptoms fit into existing dimensional models. METHOD We examined the structure of 91 anxiety, depression and somatic symptoms in a sample of 5433 primary care patients drawn from 14 countries. One-, two- and three-factor lower-order models were considered; higher-order and hierarchical variants were studied for the best-fitting lower-order model. RESULTS A hierarchical, bifactor model with all symptoms loading simultaneously on a general factor, along with one of three specific anxiety, depression and somatic factors, was the best-fitting model. The general factor accounted for the bulk of symptom variance and was associated with psychosocial dysfunction. Specific depression and somatic symptom factors accounted for meaningful incremental variance in diagnosis and dysfunction, whereas anxiety variance was associated primarily with the general factor. CONCLUSIONS The results (a) are consistent with previous studies showing the presence and importance of a broad internalizing or distress factor linking diverse emotional disorders, and (b) extend the bounds of internalizing to include somatic complaints with non-physical etiologies.

Abstract
AIM Study of spread ofa new influenza variant A(H1N1) in the world in 2009. MATERIALS AND METHODS Analysis of WHO weekly situation reports on influenza epidemic in the countries of the Northern and Southern hemisphere. RESULTS The first laboratory confirmed cases ofA/California/07/09 (H1N1) were registered in the countries of the Northern hemisphere in 10 days, and in other continents--in 1 month after the increase of morbidity. In the countries of Northern hemisphere 2 increases of A/California/07/09 (H1N1) morbidity were present--spring and autumn, and in the autumn period an increase of population morbidity, rate of hospitalization and number of lethal outcomes was noted. Only in Canada autumn increase of morbidity was not accompanied by an increase in severe influenza cases. In the Southern hemisphere a single but longer increase of morbidity was registered during the summer period. In the South-eastern Asia 2 increases were mostly present with a higher level during the first one. CONCLUSION A significant increase in morbidity in the autumn periodand its decrease at the same time in the Southern hemisphere are determined by varying seasonality of influenza in the countries of Northern and Southern hemisphere. Spring increase of morbidity was of mixed etiology; and in the autumn period influenza A/ California/07/09 (H1N1) virus dominated in the etiology of diseases.

Abstract
Long-term surveillance of antimicrobial resistance in Neisseria gonorrhoeae has been conducted in the World Health Organization (WHO) Western Pacific Region (WPR) to optimise antibiotic treatment of gonococcal disease since 1992. From 2007, the Gonococcal Antimicrobial Surveillance Programme (GASP) has been enhanced by the inclusion of data from the South East Asian Region (SEAR) and recruitment of additional centres in the WPR. Approximately 8,704 isolates of N. gonorrhoeae were examined for their susceptibility to one or more antibiotics used for the treatment of gonorrhoea, incorporating External Quality Assurance controlled methods, from reporting centres in 21 countries and/or jurisdictions. A high proportion of penicillin and/or quinolone resistance was again detected amongst isolates tested in North Asia and the WHO SEAR. In contrast, from the Pacific Island states Fiji reported low penicillin and quinolone resistance, New Caledonia again reported no penicillin resistance and little quinolone resistance, Tonga reported no penicillin resistance and there was a continued absence of quinolone resistance reported in Papua New Guinea in 2009. The proportion of gonococci reported as 'decreased susceptibility' and 'resistant' to the third-generation cephalosporin antibiotic ceftriaxone varied widely but no major changes were evident in cephalosporin minimum inhibitory concentrations (MIC) patterns in 2009. Altered cephalosporin susceptibility has been associated with treatment failures following therapy with oral third-generation cephalosporins. There is a need for revision and clarification of some of the in vitro criteria that are currently used to categorise the clinical importance of gonococci with different ceftriaxone and oral cephalosporin MIC levels. The number of instances of spectinomycin resistance remained low. A high proportion of strains tested continued to exhibit high-level plasmid mediated resistance to tetracyclines. The continuing emergence and spread of antibiotic resistant gonococci in and from the WHO WPR and SEAR suggests that surveillance programs such as GASP be maintained and expanded.

Abstract
BACKGROUND. Shift work is related to fatigue and desynchronization with the external environment. This study investigates how 6-h shifts and 12-h shifts affects sleep and safety in workers onboard offshore supply vessels, and if any differences exist between the two working schedules. MATERIAL AND METHODS. A questionnaire study was carried out in the North Sea, Australia, Africa, South America, and the Far East, with 577 participants. The offshore fleet workers gave information on parameters related to sleep disturbances, causes of sleep disturbances, and safety. Regional differences in these parameters were also investigated. RESULTS. Workers on 6-hour shifts reported significantly more sleep problems than 12-hour shift workers did (p 〈 0.01). The 6-hour workers were more affected by noise (p 〈 0.01) and shift-work itself (p 〈 0.01). CONCLUSIONS. Those working 6-hour shifts suffer more from sleep disturbances than those on 12-hour shifts, but this is not reflected in the perception of safety within the individual. Noise and shift-work itself is more of a problem in the 12-hour workers. Differences in safety culture and work morale are likely to cause the differences between regions.

Abstract
OBJECTIVE To assess the dose-response relationship between alcohol intake and relative risk of stroke and all-cause mortality among Eastern Asian men. METHODS Potential prospective cohort studies were retrieved by searching Pubmed (1966 - 2000), OVID (1980 - 2009), Embase (1980 - 2009) and ISI Web of Knowledge (1986 - 2009) using Medical Subject Headings: alcohol drinking, ethanol, stroke, cerebrovascular disease, mortality, etc; and Koreans or Japanese or Chinese. From the relevant retrieved reports, 17 prospective cohort studies fulfilling the criteria were included into the study. Information on study design, participant characteristics, amount of alcohol intake, stroke and/or all-cause mortality outcomes, control for potential confounding factors and risk estimates was abstracted by a standardized protocol. For each study, relative risk (RR) and 95% confidence interval (CI) were extracted and pooled with either a fixed or random effect model according to the results of the test of heterogeneity. RESULTS As data available for women were too limited to be included into our meta-analysis, this study focused on male subjects, ranging from 1322 to 108 461 subjects among these 17 cohort studies. Compared with nondrinkers, the RRs of ischemic stroke for those drinking alcohol ≤ 20, 21 - 40, 41 - 60, > 60 g/d, were 0.85 (0.78 - 0.93, P = 0.0002), 0.94 (0.79 - 1.11, P = 0.46), 1.08 (0.86 - 1.37, P = 0.50) and 1.24 (0.96 - 1.59, P = 0.10) respectively. Similarly, RRs of hemorrhagic stroke were 0.92 (0.75 - 1.12, P = 0.46), 1.11 (0.96 - 1.28, P = 0.17), 1.20 (0.92 - 1.56, P = 0.18) and 1.74 (1.32 - 2.28, P < 0.01); and those of all-cause mortality were 0.83 (0.75 - 0.91, P = 0.01), 0.93 (0.87 - 0.99, P = 0.03), 1.01 (0.95 - 1.07, P = 0.86) and 1.32 (1.29 - 1.36, P < 0.01) respectively. CONCLUSION In Eastern Asian men, light alcohol intake (≤ 20 g/d) is associated with a lowered risk of ischemic stroke whereas heavy alcohol intake is associated with an elevated risk of stroke, particularly hemorrhagic stroke and all-cause mortality.
