Cervical cancer continues to be an important public health problem in Thailand. While the high risk human papillomavirus (HPV) types have been established as the principle causative agent of both malignancies and the precursor lesions, cervical intraepithelial neoplasia (CIN), other factors may also be involved like other sexually transmitted diseases, as well as smoking. Chlamydia trachomatis is an obligate intracellular Gramnegative bacterium which has a tendency to cause chronic infection featuring inflammation and therefore might be expected to increase the risk of cervical cancer. In the present nested case-control study, 61 cases of cervical cancer and 288 matched controls with original serum samples were identified from the Khon Kaen Cohort, established in the North-East of Thailand, by linkage to the Khon Kaen population based cancer registry. C. trachomatis specific IgG antibodies at recruitment were measured by microimmunofluorescence and assessed for association with cervical cancer using STATA release10. No significant link was noted either with all cancers or after removal of adenocarcinomas. The results suggest no association between Chlamydia infection and cervical cancer development in North-East Thailand, but possible influencing factors must be considered in any future research on this topic.

Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

A liver fluke, Opisthorchis viverrrini (OV), is the major cause of the high incidence of cholangiocarcinoma in North-eastern Thailand. The prevalence of OV infection remains high in various parts of the country, especially in wetland rural areas where a large proportion of the community work in agriculture and continue the traditional practice of eating raw or uncooked cyprinoid fish products. The national control program seems to have had little impact in many of these areas, and it has been difficult to make precise assessments of the overall effectiveness of the program. Therefore there is a need for a community-based approach to prevent infection with the parasite, ideally involving as many players as possible. Here we document an attempt to assess the best means to prevention on the basis of a community intervention in three villages in north-east Thailand, with participation of representatives of Health Promotion Hospitals of the Ministry of Public Health with dedicated staff, but also school teachers, independent government sponsored village health volunteers, and housewives responsible for cooking and diet selection. An action plan was followed, allowing detailed discussions of practical proposals, their introduction and then repeated reflection and further proposals at the individual village level.

This qualitative research within the project entitled "Multiprofessional Intervention and training for Ongoing Volunteer-based Community Health Programs in the Northeast of Thailand (MITV-NET)" was aimed at explaining changes of health behavior of community people in the Northeast after the intervention. The participants comprised 15 community volunteers and 27 villagers. Data were collected by indepth interview, focus group discussion, participation and non-participation observation, and note taking. Analyses were conducted in parallel with data collection, through content and comparative analysis. It was found that the health behavior fell into 2 categories: easy-to-change. The former involved fun activities joined by community people that improved their health or made them recover from illnesses after a short period without becoming addicted. These activities could be done by themselves, for example, exercising and cooking. The difficult-to-change health behavior is habitual, for example, chewing betel nuts or eating uncooked food. The following factors were found affecting behavioral changes: 1) underlying disease; 2) enjoyment in doing activities; 3) habitual behaviour; 4) improved health in a short period; 5) ability of community leaders and volunteers; and 6) community health-supporting resources. It is suggested that improving people's health requires cooperation of community people through fun activities and some initial external support. People who persist in bad habits should be encouraged to stop by showing them health deteriorating effects.

This was a survey research conducted in Northestern Thailand during 2009-2010 and designed to evaluate the success of a health education program by comparing levels of health knowledge in the community before and after the launching of a Multi-professional Intervention and Training for Ongoing Volunteer-based Community Health Programme. The survey questionnaire included items about demographic characteristics and health knowledge. The participants were 1,015 members of various communities, who were randomly selected to be included in the survey before launching the intervention, and 1,030 members of the same communities randomly selected to be included in the survey after the intervention was completed. The demographic characteristics of both groups were similar. Overall knowledge and knowledge of all the diseases, except lung and cervical cancer, were significantly higher after the intervention. In conclusion, a Volunteer-based Community Health Programme has advantages for areas where the numbers of health personnel are limited. The use of trained community health volunteers may be one of the best sustainable alternative means for the transfer of health knowledge.

Background: Thailand remains a primarily agricultural country and Thai farmers are heavy users of pesticides. Coincidentally the incidence of cholangio carcinoma (CCA) is high in parts of the country, but no previous study has examined any association between the two. Materials and Methods: The present matched, case-control study covered patients admitted to Srinagarind Hospital, Khon Kaen University, Thailand. The case group comprised 210 cases diagnosed with CCA and the control group 840 diagnosed with other diseases. Cases and controls were matched for sex, age within five years, and date of admission within three months. Multiple conditional logistic regression was used for the analysis. Results: After adjusting for potential confounders, pesticide use as compared with never used pesticide was not associated with CCA (ORadj=1.11, 95% CI: 0.77, 1.60) and neither was there any significant relationship between CCA and duration of pesticide use, type or number of types pesticide use. Conclusions: The current study thus found no association between pesticide use and CCA.

The energy demand of the world is increasing rapidly, mainly using fossil energy, which causes environmental damage. The wind is free and clean energy to solve the environmental problems. Thailand is one of the developing nations, and the majority of its energy is obtained from petroleum, natural gas and coal. The objective of this study is to test the characteristics of wind energy at Khon Kaen in Thailand. The wind measurement tools, the 3-cup anemometers to measure wind speed, and wind vanes to measure wind direction, were mounted on a wind tower mast to record wind data at the heights of 60, 90 and 120 meters above ground level (AGL) for 5 years between January 2012 and December 2016. The results show that the annual mean wind speeds were 3.79, 4.32 and 4.66 m/s, respectively. The highest mean wind speeds occurred in June, August and December, in order, and the lowest occurred in September. The majority of prevailing wind directions were from the North-East and South-West directions. The average annual wind shear coefficient was 0.297. Furthermore, five wind turbines with rated power from 0.85 to 4.5 MW were selected to estimate the wind energy output and it was found that the maximum AEP and CF were achieved from the low cut-in speed and high hub-height wind turbines. This important information will help to develop wind energy applications, such as the plan to produce electricity and the calculation of the wind load that affects tall and large structures.

Opisthorchis viverrini is an ongoing public health problem in Northeast Thailand. Despite continuous efforts for decades by healthcare organizations to overcome this problem, infection rates remain high. To enable related personnel to identify and address the various issues effectively, a cross-sectional study was performed to investigate prevalence and risk factors for opisthorchiasis. The target group was 3,916 Thai residents of Northeast Thailand who were 15 or over. Participants were recruited using the 30 clusters sampling technique. The data were gathered through questionnaires, focus group discussions, in-depth interviews, and stool examinations for parasite eggs (using the Modified Kato Katz method). The data were analyzed using descriptive and inference statistics; in order to ascertain the risk factors and test them using the odds ratio and multiple logistic regressions. The prevalence of opisthorchiasis was 22.7% (95%CI: 0.26 to 0.24). The province with the highest prevalence was Nakhorn Phanom (40.9%; female to male ratio =1:1.2). The age group with the highest prevalence was 40-49 year olds. All age groups had a prevalence >20%. Four of seven provinces had a prevalence >20%. The factors related to opisthorchiasis were (a) sex, (b) age (especially > 50), (c) proximity and duration living near a water body, and (d) eating raw and/or fermented fish. In order to reduce the prevalence of opisthorchiasis, the focus in populations living in upper Northeast Thailand should be changing their eating behaviors as appropriate to their tradition and context.

Background: Cancer is a primary source of concern in Thailand and other countries around the world, including the Asian-Pacific region. Evidence supports that an important contributing cause of cancer and other chronic illnesses such as stroke, diabetes, and hypertension is excessive alcohol consumption. Studies conducted in Thailand reveal a worrisome rise in the number of new and regular drinkers in communities. Therefore, actions for primary, secondary and tertiary prevention of problem drinking are necessary. In recent years nurses in North East Thailand have been developing and implementing the Khon Kaen Family Health Nursing model to embed disease prevention in communities through the actions of family health nurses and local family health leaders. Aim: The aim of this qualitative research was to better understand the experiences of the local family health leaders using this model and to synthesize lessons learned. Materials and Methods: As part of a participatory action research approach involving analysis of focus group discussions and individual interviews, the experiences of 45 family health leaders were synthesized. Results: Four main themes were identified, namely: i) Family first: role modeling beginning at the personal and family level. ii) Local leverage: using village community forums to reduce alcohol drinking. iii) Gentle growth: making the first step and treading gently; and iv) Respect, Redemption, Rehabilitation: valuing the person to re-integrate them in the village society. Conclusions: As alcohol consumption in the village declined significantly following the prevention program, these findings illuminate how low-tech integrated prevention approaches may be very useful, particularly in rural communities. The lessons learned may have relevance not only in Thailand but in other countries seeking to prevent and mitigate behavior that conduces to diseases such as cancer.
