Study protocol for a mixed methods approach to optimize colorectal cancer screening in Malaysia: Integrating stakeholders insights and knowledge-to-action framework.

Introduction: Colorectal cancer is a growing global health concern and the number of reported cases has increased over the years. Early detection through screening is critical to improve outcomes for patients with colorectal cancer. In Malaysia, there is an urgent need to optimize the colorectal cancer screening program as uptake is limited by multiple challenges.

Genetic diversity of hepatitis B co-infection with hepatitis C, D and E viruses among Malaysian chronic hepatitis B patients.

Background: Hepatitis B virus co-infection with other strains of viral hepatitis is associated with increased risk of liver cirrhosis and hepatic decompensation.

Objectives: This is a prevalence study that assessed the genetic diversity of chronic hepatitis B patients and coinfection.

Methods: Chronic hepatitis B patients enrolled in this study were tested for antibodies of other hepatitis viruses using ELISA kits.

Quantitative Hepatitis B e Antigen: A Better Predictor of Hepatitis B Virus DNA than Quantitative Hepatitis B Surface Antigen.

Background: Hepatitis B surface antigen is usually secreted by infected hepatocytes in the form of subviral particles rather than infectious virions, while the hepatitis B e antigen originates from the core gene and is modified and secreted by hepatocytes into the circulation and functions as a marker of active viral replication. This study aimed to study the relationship between HBV DNA and quantitative hepatitis B surface and e antigen in Malaysian patients.

Methods: A total of 82 chronic hepatitis B patients were recruited for this study from the Hepatology Department of Selayang Hospital.
