Purpose: As people living with thalidomide embryopathy (TE) are now entering their seventh decade, we examine the impact of ageing and the prevalence of comorbid health conditions reported in holistic needs assessments (HNAs) by individuals with TE, compare it with an age-matched sample of the general population, and explore the relationship between comorbidities and TE pattern of impairment.

Materials And Methods: The HNA categories were mapped and compared to those of the Health Survey for England (HSE) and analysed across four impairment groups (A-D).

Results: 94% (392/415) of individuals with TE residing in the UK participated in the HNA and consented to a secondary analysis of the data.

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).

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.

The toll-like receptors (TLRs) mediate the recognition of Helicobacter pylori and initiate the innate immune response to infection. We hypothesized those genetic polymorphisms in the TLR1, TLR2, TLR4, and TLR10 influence bacterial infection, affecting susceptibility H. pylori to disease outcomes.

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.

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.

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.

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.

Helicobacter pylori infection plays an important role in the pathogenesis of chronic gastritis, peptic ulcer disease and gastric malignancy. A diagnosis of infection is thus an important part of a treatment strategy of many gastrointestinal tract diseases. Many diagnostic tests are available but all have some limitations in different clinical situations and laboratory settings.

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.

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.

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.

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.

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.
