Validation and efficacy of the Varix Trainer model as a Training device for esophagogastroduodenoscopy.

The Varix Trainer model 1 (VTM1) was created for trainees to safely practice basic endoscope manipulation skills. The VTM1 was tested to see if it could distinguish levels of endoscope manipulation skills (construct validity) and whether training with it could improve these skills faster (content validity). We enrolled 23 novice endoscopists, 18 second-year trainees, and 13 expert endoscopists.

A surveillance for hepatitis C virus infection in northeastern, Thailand: a 10-year cohort.

Comparison between using hepatocellular carcinoma (HCC) risk scores and the HCC national guideline to identify high-risk chronic hepatitis B patients for HCC surveillance in Thailand.

Background And Aim: Hepatocellular carcinoma (HCC) surveillance in hepatitis B virus (HBV) patients is currently based on age/sex/cirrhosis, uses ultrasound abdomen every 6-12 months, and is a resource burden. HCC risk scores have been developed to classify HCC risk for surveillance. The number of HBV patients needing surveillance when HCC risk scores are used may be different from the current recommendation with implications on the resources needed for HCC surveillance.

Surveillance for hepatitis B virus seroprevalence nearly 30 years after the implementation of a national vaccination program.

Introduction: Hepatitis B virus (HBV) infection is associated with cirrhosis and hepatocellular carcinoma. Vaccination is one aspect of public health policy aimed at eliminating HBV infection. After the implementation of an HBV vaccination program for newborns in Thailand, the estimated residual infection rate was 3.
