Risk factors of cholangiocarcinoma in areas not endemic for liver fluke infection.

Background: Thailand has the world's highest prevalence of cholangiocarcinoma (CCA), especially in the endemic area of liver fluke infection. However, other regions of Thailand still have relatively high CCA prevalence.

Objectives: We aimed to determine CCA risk factors in areas not endemic for OV infection.

The first human case report of molecularly confirmed co-infection of and A case report.

Co-infection with and has been rarely reported. To date, there are only two co-infection case reports from Croatia and China which diagnosed the infections mainly through the use of serological tests. In this report, we present the first case of molecularly confirmed bacteremia and spondylodiscitis co-infection in a goat dairy farmer who presented with lumbosacral spondylodiscitis and bilateral psoas abscesses.

Immunogenicity and safety of heterologous versus homologous prime-boost schedules with inactivated and adenoviral vectored SARS-CoV-2 vaccines - A prospective multi-center study.

Background: During the peak of Coronavirus disease (COVID-19) pandemic in Thailand when the emergence of delta variant reduced the efficacy of inactivated vaccine, Thailand had abundance of inactivated vaccine but mRNA vaccine was not available and the supply of adenoviral-vectored vaccine was limited. The heterologous vaccination using CoronaVac and ChAdOx1-nCoV-19 vaccines was applied. We aim to compare the immunogenicity of immune response of primary vaccination with homologous ChAdOx1 nCoV-19 and heterologous vaccination with CoronaVac and ChAdOx1 nCoV-19.
