Abstract
The carcinogenic liver fluke, Opisthorchis viverrini, is a serious health problem in Southeast Asia where infection is associated with cholangiocarcinoma, a major cause of death in Thailand. This cross-sectional study aimed to screen for O. viverrini infection among a Thai rural population of 560 individuals from Nakhon Ratchasima, Khonkaen, and Chaiyaphum provinces with a verbal screening test with a mobile application (OvApp). Faecal samples were also processed with a mini-parasep sf parasite faecal concentrator. The infection rate of O. viverrini was found to be 2.86%. The majority of infections were detected in males aged 41–50, with primary school being their highest education level, and who were engaged in agricultural occupations. In screening for O. viverrini infection, the OvApp had a high sensitivity (87.5%), specificity (94.6%), negative predictive value (98.9%), and accuracy (98.6%). The positive predictive value was 70.0% for the OvApp. The observed agreement was substantial for this application (k-value = 0.64) indicated that it is a potentially useful tool for decreasing the cost of large-scale O. viverrini screening.

Abstract
Opisthorchis viverrini is a serious problem in Thailand, Cambodia, the Lao People's Democratic Republic and Vietnam. Active surveillance and eradication of O. viverrini is required. A cross-sectional study of 403 immigrant workers was conducted between October 2016 and June 2017 in Nakhon Ratchasima, Thailand. Stool samples were analysed via the formalin-ether concentration technique, with subsequent data analysis performed using descriptive statistics and logistic regression. Overall infection was 24.1% and the results reveals an O. viverrini infection rate was 11.9%. O. viverrini infection was identified in 25.6% of Cambodians, 15.3% of Laotians and 3.6% workers from Myanmar sampled. The majority of infections were found in males, aged e"40 years and working as labourers. Raw or undercooked cyprinoid fish consumption was associated with an elevated risk for O. viverrini infection (ORadj = 2.2, 95% CI = 1.2-4.0). Other intestinal helminthic infections were hookworm (5.5%), Trichuris trichiura (5.2%), Strongyloid stercoralis (0.5%), Ascaris lumbricoides (0.5%) and Taenia spp. (0.5%), respectively. This is the first study to report O. viverrini among immigrant workers in Thailand; therefore, active surveillance is needed among migrant workers to identify and treat O. viverrini infection.

Abstract
Opisthorchis viverrini is a major health problem in many part of Southeast Asia. Therefore, this study aimed to detect Opisthorchis viverrini infection among migrant workers in Thailand by using three coprological concentration methods. A cross-sectional study was conducted among 147 migrant workers in Thailand. Fecal samples were processed by the modified formalin ether concentration technique, the Kato Katz thick smear, and the miniparasep solvent free parasite fecal concentrator. Specificities, sensitivities, negative predictive values, positive predictive values, Kappa indexes were analyzed with SPSS version 22. The infection rate with opisthorchiasis was 27.2%. The parameters measured for the modified formalin ether concentration technique, Kato Katz thick smear, and mini-parasep solvent free parasite fecal concentrator methods respectively were as follows: infection rates (23.1%, 12.9%, and 22.4%), sensitivities (85.0%, 47.5%, and 82.5%), specificities (100%, 100%, and 100%), positive predictive values (100%, 100%, and 100%), and negative predictive values (94.7%, 83.6%, and 93.9%). The kappa index value of diagnostic agreement between formalin ether concentration technique and mini-parasep solvent free parasite fecal concentrator showed substantial agreement for O. viverrini. In conclusion, the calculated analytical sensitivity, and negative predictive values indicate that modified formalin ether concentration technique and mini-parasep solvent free parasite fecal concentrator are more accurate in detecting O. viverrini infections. The study indicates that the mini-parasep solvent free parasite fecal concentrator method was the method with high potential to be used in routine laboratory and community diagnosis for opisthorchiasis.

Abstract
BACKGROUND The tumor suppressor p53 is as a regulator of cell proliferation, apoptosis and many other biological processes as well as external and internal stress responses. Mdm2 SNIP309 is a negative regulator of 53. Therefore, this study aimed to determine the role of the Mdm2 SNIP 309 polymorphism in the gastric mucosal morphological patterns in patients with Helicobacter pylori associated gastritis. MATERIALS AND METHODS A prospective cross-sectional study was carried out from November 2014 through November 2015. Biopsy specimens were obtained from patients and infection was proven by positive histology. Gastric mucosa specimens were sent to the Molecular Genetics Unit, Institute of Medicine, Suranaree University of Technology where they were tested by molecular methods to detect the patterns of Mdm2 SNIP 309 polymorphism using the real-time PCR hybridization probe method. The results were analyzed and correlated with gastric mucosal morphological patterns by using C-NBI endoscopy. RESULTS A total of 300 infected patients were enrolled and gastric mucosa specimens were collected. In this study the percentage of Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous was 78% and 19 % respectively whereas Mdm2 SNIP309 G/G homozygous was 3%. Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygosity correlated with type 1 to type 3 gastric mucosal morphological patterns (P<0.01) whereas Mdm2 SNIP309 G/G homozygous correlated with type 4 and type 5 (P<0.01). CONCLUSIONS Our study finds the frequency of Mdm2 SNIP309 G/G in a Thai population is very low, and suggests that this can explain ae Thailand enigma. Types 1 to type 3 are the most common gastric mucosal morphological patterns according to the unique genetic polymorphism of MDM2 SNIP 309 in the Thai population.

Abstract
Several infectious agents are considered to be causes of cancer in human, mainly hepatitis B and C viruses, high-risk human pailloma viruses, Helicobacter pylori, Clonorchis sinensis, and Opisthorchis viverrini. Here we described the evident research and the association between Helicobacter spp. and biliary tract cancer particularly cholangiocarcinoma (CCA). Global epidemiological studies have suggested that Helicobacter spp. are possible risk factors for biliary tract diseases. Molecular studies support a linkage of Helicobacter spp. with CCA development. H. pylori, H. bilis, and H. hepaticus, are found in CCA, but the most common species are H. pylori and H. bilis. The type of CCA are associated with Helicobacter spp. include extrahepatic CCA, and common bile duct cancer. Up to the present, however, the results from different regions, materials and methods, sub-sites of cancer, and controls have not been consistent, thus introducing heterogeneity. Therefore, a comparison between co-Helicobacter spp.-CCA in the countries with low and high incident of CCA is required to settle the question. Furthermore, clarifying variation in the role of Helicobacter species in this CCA, including pathogenesis of CCA through enhanced biliary cell inflammation and proliferation, is necessary.

Abstract
The Mini Parasep SF fecal parasite concentrator (MPSFC) is a new modification of the closed concentration system, which can easily be adopted in any routine clinical pathology laboratory. Here we describe our experience with the system in diagnosing Opisthorchis viverrini. A total of 199 fecal samples was submitted for routine examination in the clinical pathology laboratory of Suranaree University of Technology hospital, Nakhon Ratchasima province, Thailand, during August to October 2015. Out of all samples examined, 10 (5.03%) were positive with intestinal parasites including O. viverrini (2.01%), followed by Strongyloided stercoralis (1.51%), Hookworm (0.5%), Taenia spp. (0.5%), and Entamoeba coli (0.5%). Regarding the distribution of intestinal parasites in relation to the methods used, and found that 4 samples (2.01%) were positive using the direct wet smear method while 10 (5.03%) were positive with the Mini Parasep SF method; the difference was statistically significant (X2-test = 116.506, p-value =0.001). Mean time for processing using the Parasep system was 6.03 min/ sample, the conventional direct wet smear method at 0.3 min/sample. Cost per test, conventional direct wet smear method costing less than the Parasep method at USD 0.74/sample versus USD 1.47/sample. This first report of O. viverrini detection using MPSFC indicates that Parasep concentration test is useful in the routine laboratory, increasing the yield of parasites as compared to direct microscopy, but with greater processing time and cost. Further comparisons between the Parasep concentration test and common methods for O. viverrini detection are required, particularly concerning use in epidemiological surveys.

Abstract
BACKGROUND Colorectal polyps are common in Thailand, particularly in the northeastern region. The present study aimed to determine any correlation between Helicobacter pylori-associated gastritis and colorectal polyps in the Thai population. MATERIALS AND METHODS A total of 303 patients undergoing esophagogastroduodenoscopy with colonoscopy for investigation of chronic abdominal pain participated in this study from November 2014 to October 2015. A diagnosis of Helicobacter pylori associated gastritis was made if the bacteria were seen on histopathological examination and a rapid urease test was positive. Colorectal polyps were confirmed by histological examination of colorectal biopsies. Patient demographic data were analyzed for correlations. RESULTS The prevalence of colorectal polyps was 77 (25.4%), lesions being found more frequently in Helicobacter pylori infected patients than non-infected subjects [38.4% vs. 12.5%; Odds Ratio (OR) (95% CI): 2.26 (1.32 - 3.86), p < 0.01]. Patients with Helicobacter pylori - associated gastritis were at high risk of having adenomas featuring dysplasia [OR (95% CI): 1.15 (1.16 - 7.99); P = 0.02]. There was no varaition in location of polyps, age group, sex and gastric lesions with respect to Helicobacter pylori status. CONCLUSIONS This study showed that Helicobacter pylori associated gastritis is associated with an increased risk of colorectal polyps, especially adenomas with dysplasia in the Thai population. Patients with Helicobacter pylori-associated gastritis may benefit from concurrent colonoscopy for diagnosis of colorectal polyps as a preventive and early treatment for colorectal cancer.

Abstract
BACKGROUND Helicobacter pylori infection and premalignant gastric mucosa can be reliably identified using conventional narrow band imaging (C-NBI) gastroscopy. The aim of our study was to compare standard biopsy with site specific biopsy for diagnosis of H. pylori infection and premalignant gastric mucosa in daily clinical practice. MATERIALS AND METHODS Of a total of 500 patients who underwent gastroscopy for investigation of dyspeptic symptoms, 250 patients underwent site specific biopsy using C-NBI (Group 1) and 250 standard biopsy (Group 2). Sensitivity, specificity, and positive and negative predictive values were assessed. The efficacy of detecting H. pylori associated gastritis and premalignant gastric mucosa according to the updated Sydney classification was also compared. RESULTS In group 1 the sensitivity, specificity, positive and negative predictive values for predicting H. pylori positivity were 95.4%, 97.3%, 98.8% and 90.0% respectively, compared to 92.9%, 88.6%, 83.2% and 76.1% in group 2. Site specific biopsy was more effective than standard biopsy in terms of both H. pylori infection status and premalignant gastric mucosa detection (P<0.01). CONCLUSIONS Site specific biopsy using C-NBI can improve detection of H. pylori infection and premalignant gastric mucosa in daily clinical practice.

Abstract
BACKGROUND Evidence shows that lipid ratios perform better than individual lipids in predicting cardiovascular risk. The lipid ratio serves as a quick and simple tool for identifying subclinical atherosclerosis. The population at risk especially perimenopausal and menopausal women should be monitoring to prevent cardiovascular disease in the future. OBJECTIVE To examine the association between lipid ratios and subclinical atherosclerosis by carotid intima media thickness (CIMT) in perimenopausal/menopausal women. MATERIAL AND METHOD A cross-sectional study was conducted with 130 participants aged 40 to 80 years between February 2015 and January 2016 in Suranaree University of Technology Hospital, Thailand. CIMTs were assessed using a highresolution B mode ultrasound system. Traditional anthropometry, body mass index (BMI), waist circumference (WC), and parameters including blood pressure, fasting plasma glucose, lipid profile [Total cholesterol (TC), Triglyceride (TG), Highdensity lipoprotein cholesterol (HDL-C) and Low-density lipoprotein cholesterol (LDL-C)], and CIMT were assessed in all subjects. All lipid ratios were calculated. RESULTS One hundred thirty perimenopausal/menopausal participants were included in this study. Of those participants, 41% were central obese phenotype and 22% had abnormal CIMT that can identify atherosclerosis. Age and systolic blood pressure in atherosclerosis group were higher than normal CIMT group; <0.01 and <0.01, respectively. Lipid ratio in normal CIMT was higher than atherosclerotic group but not statistically significance except TG/HDL-C (p = 0.03). All lipid ratios and single lipid parameters lacked prediction for the presence of early atherosclerosis. CONCLUSION All of lipid ratios, TC/HDL-C, TG/HDL-C, and LDL-C/HDL-C were not identified as early subclinical atherosclerosis among perimenopausal/menopausal women.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is a bile duct cancer. It includes intra-and extra-hepatic bile duct. It is most commonly found in Thailand particularly in the northeast and north region. Those regions have been reported as the highest of incident of the world. OBJECTIVE Primary car interven in the risk areas of CCA among population in Nakhon Ratchasima province,Thailand. MATERIAL AND METHOD A community-based study was conducted among three districts of Nakhon Ratchasima province, Thailand including Bua Yai, Chum Phuang, and Mueang Yang district between July and December 2015. Mix method was used in this study that included cross-sectional survey, action research, and application of Geographic Information System. The study was composed of five steps, develop Korat CCA network, CCA screening by using Korat CCA verbal screening test, detection of liver fluke and CCA in the population at risk by using Kato Katz thick smear technique and ultrasonography, health behavior modification, and development of Geographic Information System for CCA database. RESULTS Three hundred fifty five participants were tested for liver fluke infection and the infection rate was found to be 2.25%. Eight cases from 88 participants at risk had a dilated bile duct. Populations at risk in each district were selected for health modification briefing that used the social engagement model. Seven community rules were agreed, cooked fish consumption, stop under-cooked fish, hygienic defecation, CCA campaign, food safety club, annual health check, an ongoing monitoring by village health volunteer and local public health officer. CONCLUSION Infection in Nakhon Ratchasima is high. A community briefing and rules were agreed. A geovisual display of the population at risk for CCA is now available.

Abstract
BACKGROUND Obesity is associated with a major prevalence of cardiovascular risk factors and high risk of cardiovascular events and contributes to the increase in cardiovascular morbidity and mortality worldwide. Abdominal obesity is a main predictive factor of the metabolic syndrome, so it is certain that it represents a preferable marker of cardiovascular risk than generalized obesity. Visceral adiposity index (VAI) has recently been suggested to be used as a surrogate of visceral adiposity. OBJECTIVE We compared the predictive abilities of the VAI with those of simple anthropometric measures in preclinical atherosclerosis, as assessed by ultrasonographic measurement of carotid intima media thickness (CIMT). MATERIAL AND METHOD This is observational cross-sectional study involving 130 menopausal status women voluntarily recruited from Suranaree University of Technology Hospital, Thailand. Body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), waist-height ratio (WHtR) and lipid profile were determined. VAI was calculated. CIMT was assessed using a high-resolution B mode ultrasound system. RESULTS Total 114/130 menopausal status participants, 16 participants were excluded from morbid obesity and high triglyceride >400 mg/dL. About 22.3% had preclinical atherosclerosis on carotid ultrasound. Positive correlation was found between CIMT and WC (r = 0.20, p = 0.04), and WHR (r = 0.25, <0.01) and WHtR (r = 0.24, p = 0.01). However, there was no correlation between VAI and CIMT. CONCLUSION Using VAI instead of simple anthropometric measures may lead to loss of much information needed for predicting preclinical atherosclerosis. WC, WHR, and WHtR were both superior to VAI in predicting CIMT.

Abstract
BACKGROUND The commonly held view of the tumor suppressor p53 is as a regulator of cell proliferation, apoptosis and many other biological processes as well as external and internal stress responses. Mdm2 SNIP309 is a negative regulator of p 53. Therefore, this study aimed to determine the correlation between the patterns of Mdm2 SNIP 309 and the inflammation grading of Helicobacter pylori associated gastritis in a Thai population. MATERIALS AND METHODS A cross-sectional study was carried out from November 2014 through June 2015. Biopsy specimens were obtained from infected patients and infection was proved by positive histology. The gastric mucosa specimens were sent to the Molecular Genetic Unit, Institute of Medicine, Suranaree University of Technology where they were tested by molecular methods to detect the patterns of Mdm2 SNIP 309 using the real-time PCR hybridization probe method. The results were analyzed and compared with the Updated Sydney classification. RESULTS A total of 100 infected patients were interviewed and gastric mucosa specimens were collected. In this study the percentage of Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous was 78% and 19 % respectively whereas Mdm2 SNIP309 G/G homozygous was 3%. Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous correlated with mild to moderate inflammation (P<0.01) whereas Mdm2 SNIP309 G/G homozygous correlated with severe inflammation (P<0.01). CONCLUSIONS Our study found the frequency of Mdm2 SNP309 G/G in our Thai population to be very low, and suggests that this can explain to some extent the low incidence of severe inflammation and gastric cancer changes in the Thai population. Mild to moderate inflammation are the most common pathologic gradings due to the unique genetic polymorphism of Mdm2 SNIP 309 in the Thai population.

Abstract
BACKGROUND Helicobacter pylori plays an important role in gastric cancer, which has a relatively low inciduence in Thailand. MDM2 is a major negative regulator of p53, the key tumor suppressor involved in tumorigenesis of the majority of human cancers. Whether its expression might explain the relative lack of gastric cancer in Thailand was assessed here. MATERIALS AND METHODS This single-center study was conducted in the northeast region of Thailand. Gastric mucosa from 100 patients with Helicobacter pylori associated gastritis was analyzed for MDM2 SNP309 using real-time PCR hybridization (light-cycler) probes. RESULTS In the total 100 Helicobacter pylori associated gastritis cases the incidence of SNP 309 T/T homozygous was 78 % with SNP309 G/T heterozygous found in 19% and SNP309 G/G homozygous in 3%. The result show SNP 309 T/T and SNP 309 G/T to be rather common in the Thai population. CONCLUSIONS Our study indicates that the MDM2 SNP309 G/G homozygous genotype might be a risk factor for gastric cancer in Thailand and the fact that it is infrequent could explain to some extent the low incidence of gastric cancer in the Thai population.

Abstract
Opisthorchis viverrini is remains a public health problem in Thailand, particularly in the northeast and north regions which have the highest incidences of chonalgiocarcinoma (CCA). O. viverrini causes the disease opithorchiasis, and its has been classified as a group 1 biological carcinogen. Humans, dogs, and cats become infected with O. viverrini by ingesting raw or undercooked fish containing infective metacercariae. The first human cases of O. viverrini infection were reported in Thailand 100 years ago, and it's still a problem at the community level. Based on data for the year 2009, more than 6 million people were infected with O. viverrini. Associated medical care and loss of wages in Thailand costs about $120 million annually. This review highlights the current status of O. viverrini infection in communities of Thailand through active surveillance for the five years period from 2010 and 2015. A total of 17 community-based surveys were conducted, most in the northeast region. Some 7 surveys demonstrated a high prevalence over 20%, and the highest was 45.7%. Most commonly infection was found in age group of 35 years and older, males, and agricultural workers. Although, the national prevalence may be decreasing but the results show that the O. viverrini infection is still high in communities of the northeast region. Therefore, the focus in populations living in northeast Thailand should be screening of infection and changing their eating behavior.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is a serious public health problem in the Northeast of Thailand. CCA is considered to be an incurable and rapidly lethal disease. Knowledge of the distribution of CCA patients is necessary for management strategies. OBJECTIVES This study aimed to utilize the Geographic Information System and Google EarthTM for distribution mapping of cholangiocarcinoma in Satuek District, Buriram, Thailand, during a 5-year period (2008-2012). MATERIALS AND METHODS In this retrospective study data were collected and reviewed from the OPD cards, definitive cases of CCA were patients who were treated in Satuek hospital and were diagnosed with CCA or ICD-10 code C22.1. CCA cases were used to analyze and calculate with ArcGIS 9.2, all of data were imported into Google Earth using the online web page www.earthpoint.us. Data were displayed at village points. RESULTS A total of 53 cases were diagnosed and identified as CCA. The incidence was 53.57 per 100,000 population (65.5 for males and 30.8 for females) and the majority of CCA cases were in stages IV and IIA. The average age was 67 years old. The highest attack rate was observed in Thung Wang sub-district (161.4 per 100,000 population). The map display at village points for CCA patients based on Google Earth gave a clear visual deistribution. CONCLUSIONS CCA is still a major problem in Satuek district, Buriram province of Thailand. The Google Earth production process is very simple and easy to learn. It is suitable for the use in further development of CCA management strategies.

Abstract
Cholangiocarcinoma (CCA) is a serious problem in Thailand, particularly in the northeastern region. Active surveillance in rural communities with an appropriat low-cost screening tool is required to facilitate early detection. Therefore, this study aimed to investigate the population at risk of CCA in Bua Yai district, Nakhon Ratchasima province, Northeastern Thailand using the Korat-CCA verbal screening test (KCVST) during June to October 2015. Reliability of KCVST demonstrated a Cronbach alpha coefficient=0.75 Stepwise-multiple regression showed that alcohol consumption was important for CCA screened, followed by agriculture and pesticide use, under-cooked cyprinoid fish consumption, praziquantel use, naïve northeastern people, opisthorchiasis, family relatives with CCA, and cholangitis or cholecystitis or gallstones, respectively. Population at risk for CCA was classified to low risk (63.4%), moderate risk (33.7%), and high risk (1.32%) for CCA. When CCA was screened using ultrasonography, 4 of 32 high risk participants had an abnormal biliary tract with dilated bile ducts. This study indicates that KCVST is a potential useful too which decrease the cost of large scale CCA screening.

Abstract
BACKGROUND Cholangiocarcinoma (CCA), a major problem of health in Thailand, particularly in Northeastern and Northern regions, is generally incurable and rapidly lethal because of presentation in stage 3 or 4. Early diagnosis of stage 1 and 2 could allow better survival. Therefore, this study aimed to provide a distribution map of populations at risk for CCA in BuaYai district of Nakhon Ratchasima province, Northeast Thailand. MATERIALS AND METHODS A cross-sectional survey was carried out in 10 sub-districts and 122 villages, during June and November 2015. The populations at risk for CCA were screened using the Korat CCA verbal screening test (KCVST) and then risk areas were displayed by using Google map (GM). RESULTS A total of 11,435 individuals from a 26,198 population completed the KCVST. The majority had a low score of risk for CCA (1-4 points; 93.3%). High scores with 6, 7 and 8 points accounted for 1.20%, 0.13% and 0.02%. The population at risk was found frequently in sub-district municipalities, followed by sub-district administrative organization and town municipalities, (F=396.220, P-value=0.000). Distribution mapping comprised 11 layers: 1, district; 2, local administrative organization; 3, hospital; 4, KCVST opisthorchiasis; 5, KCVST praziquantel used; 6, KCVST cholelithiasis; 7, KCVST raw fish consumption; 8, KCVST alcohol consumption; 9, KCVST pesticide used; 10, KCVST relative family with CCA; and 11, KCVST naive northeastern people. Geovisual display is now available online. CONCLUSIONS This study indicated that the population at high risk of CCA in Bua Yai district is low, therefore setting a zero model project is possible. Key success factors for disease prevention and control need further study. GM production is suitable for further CCA surveillance and monitoring of the population with a high risk score in this area.

Abstract
BACKGROUND Liver fluke infection with Opisthorchis viverrini and its associated cholangiocarcinoma constitute a serious problem in Thailand. Healthy behavior can decrease infection, therefore, the investigation of knowledge, attitude, and practice is need required in high risk areas. OBJECTIVE This study aimed to investigate the behavior and perceptions regarding liver fluke. MATERIALS AND METHODS A cross-sectional descriptive study was conducted in Chum Phuang district of Nakhon Ratchasima province, Thailand during July to November 2015. A total 80 participants who had screened with verbal screening test, stool examination, and ultrasonography, were purposive selected and completed a pre-designed questionnaire (Kruder-Richardon-20=0.80, Cronbach's alpha coefficient=0.82 and 0.79). T-test, ANOVA, and Pearson correlation test were used for analyzed data. RESULTS The results reveal that O. viverrini infection was 1.25%, and 3 patients had a dilated bile ducts. The participants had a high knowledge, attitude, and practice regarding liver fluke. The education, occupation, and income, were statistical significant to attitude regarding liver fluke. Nurses and television were the main sources of information regarding liver fluke, with statistical significance(p-value <0.05). Knowledge was significantly associated with attitude and practice (p-value<0.05). CONCLUSIONS Participants had good behavior regarding liver fluke. Improvement of knowledge and attitude is influenced to practical change regarding this carcinogenic fluke. In addition, nurse and television are the main information resources for key success in increasing people perception for disease prevention and control in this area.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is a serious health problem in Thailand, particularly in northeastern and northern regions, but epidemiological studies are scarce and the spatial distribution of CCA remains to be determined. A database for the population at risk is required for monitoring, surveillance and organization of home health care. This study aim was to geo-visually display the distribution of CCA in northeast Thailand, using a geographic information system and Google Earth. MATERIALS AND METHODS A cross-sectional survey was carried out in 9 sub-districts and 133 villages in Chum Phuang district, Nakhon Ratchasima province during June and October 2015. Data on demography, and the population at risk for CCA were combined with the points of villages, sub-district boundaries, district boundaries, and points of hospitals in districts, then fed into a geographical information system. After the conversion, all of the data were imported into Google Earth for geo-visualization. RESULTS A total of 11,960 from 83,096 population were included in this study. Females and male were 52.5%, and 47.8%, the age group 41-50 years old 33.3%. Individual risk for CCA was identifed and classified by using the Korat CCA verbal screening test as low (92.8%), followed by high risk (6.74%), and no (0.49%), respectively. Gender (X2-test=1143.63, p-value= 0.001), age group (X2-test==211.36, p-value=0.0001), and sub-district (X2-test=1471.858, p-value=0.0001) were significantly associated with CCA risk. Spatial distribution of the population at risk for CCA in Chum Phuang district was viewed with Google Earth. Geo-visual display followed Layer 1: District, Layer 2: Sub-district, Layer 3: Number of low risk in village, Layer 4: Number of high risk in village, and Layer 5: Hospital in Chum Phuang District and their related catchment areas. CONCLUSIONS We present the first risk geo-visual display of CCA in this rural community, which is important for spatial targeting of control efforts. Risk appears to be strongly associated with gender, age group, and sub-district. Therefor, spatial distribution is suitable for the use in the further monitoring, surveillance, and home health care for CCA.

Abstract
Opisthorchis viverrini infection is associated with cholangiocarcinoma particularly in the cases of chronic or re-infection. This presents a serious health problem in northeastern and northern Thailand. A community base approach is required for surveillance. Therefore, in a pilot project, re-examination of O. viverrini infection was conducted in the 3 districts of Nakhon Ratchasima province, Thailand, during June and October 2015. A total of 355 participants from a 194,152 population, was selected through multi-stage sampling. O. viverrini infection was determined using modified Kato Katz thick smear technique. Participants were 229 males and 126 females, and aged ≥30 years old. Prevalence of O. viverrini infection was 2.25% (8/355 participants). O. viverrini infection was slightly higher in females (3.17%), and age group between 41-50 years (4.49%). Mueang Yang district had a highest of O. viverrini infection rate (2.82%), and followed by Bua Yai (2.48%), and Chum Phuang (1.84%), respectively. O. viverrini infection rate was increased from year 2012 to 2015 particularly in Bua Yai and Mueang Yang. These re-examinion results indicate that opisthorchiasis is still problem in community of Nakhon Ratchasima province, therefore, the provincial-wide scale is need required. Furthermore health education is need intervened in the infected group, and screening of cholangiocarcinoma is urgently concerned.

Abstract
BACKGROUND Helicobacter pylori is now recognized as a causative factor of chronic gastritis, gastroduodenal ulcers, gastric cancer and mucosaassociated lymphatic tissue lymphoma. Tolllike receptors are important bacterial receptors in gastric epithelial cell signaling transduction and play critical roles in gastric carcinogenesis. MATERIALS AND METHODS A total of 400 patients undergoing esophagogastroduodenoscopy for investigation of chronic abdominal pain were genotyped for singlenucleotide polymorphisms (SNPs) in TLR1 (rs4833095) using TagMan SNPs genotyping assay by realtime PCR hybridization. Relationships with susceptibility to H. pylori infection and premalignant gastric mucosa morphological patterns, classified by magnifying NBI endoscopy, were investigated. RESULTS The percentages of TLR1 rs4833095, CC homozygous, CT heterozygous and TT homozygous cases were 34, 46.5 and 19%, respectively. CC showed statistical differences between H. pylori positive and negative cases (P<0.001). CT and TT correlated with type 1 and type 2 gastric mucosal morphological patterns (P<0.01) whereas CC correlated with types 3 and 4 (P<0.01). CONCLUSIONS This study demonstrated good correlation of TLR1 rs4833095 genotype with severity of inflammation in H. pylori infected gastric mucosa according to gastric mucosal morphologic patterns with magnifying NBI endoscopy.

Abstract
Dyspepsia affects up to 40 percent of adults each year and is often diagnosed as functional (nonulcer) dyspepsia. The defining symptoms are postprandial fullness, early satiation, or epigastric pain or burning in the absence of causative structural disease. These symptoms may coexist with symptoms of functional gastrointestinal disorders, such as gastroesophageal reflux and irritable bowel syndrome, as well as anxiety and depression. The history and physical examination can help identify other possible causes of the symptoms. Warning signs of serious disease, such as cancer, are unintended weight loss, progressive dysphagia, persistent vomiting, evidence of gastrointestinal bleeding, and a family history of cancer. In these cases, more extensive laboratory investigation, imaging, and endoscopy should be considered as clinically indicated. During the initial evaluation, a test-and-treat strategy to identify and eradicate Helicobacter pylori infection is more effective than empiric treatment and more cost-effective than initial endoscopy. Eradication of H. pylori helps one out of 15 patients with functional dyspepsia diagnosed by endoscopy, but may not be cost-effective. Treatment options that may be beneficial for functional dyspepsia include histamine H2 blockers, proton pump inhibitors, and prokinetic agents. Although psychotropic medications and psychological interventions have no proven benefit in patients with functional dyspepsia, they are appropriate for treating common psychiatric comorbidities.
