This study aimed to develop an extraction-free method for quantitative and qualitative detection of HBV DNA compared to traditional nucleic acid extraction. Paired serum and dried blood spot (DBS) samples from 67 HBsAg-positive and 67 HBsAg-negative individuals were included. Two samples with known HBV DNA titers (~ 10 copies/mL) were examined by extraction-free detection using three surfactants (0.

- A study was conducted to create conversion equations between five different quantitative tests for SARS-CoV-2 anti-S antibodies and to evaluate the agreement of three qualitative tests for anti-N antibodies among vaccinated healthcare workers in Japan.
- Strong correlations were found between the quantitative tests for anti-S antibodies, allowing for the development of conversion formulas to compare results across different tests.
- The agreement among the qualitative anti-N antibody tests was substantial overall but decreased over time, indicating potential challenges in comparing COVID-19 exposure studies based on these measurements.
Introduction Despite the implementation of countermeasures and mass vaccination programs, the COVID-19 pandemic incidence was a vital public health concern. This study aimed to explore the dynamics of COVID-19 cases and assess the association of COVID-19 pandemic epidemiological data with meteorological factors in Hiroshima Prefecture compared to Japan. Methods We analyzed COVID-19 pandemic data in Japan's Hiroshima Prefecture from January 16, 2020, to May 9, 2023.

- The study developed a cost-effective in-house ELISA for detecting hepatitis E virus (HEV) in pregnant women in Siem Reap, Cambodia.
- Out of 1565 tested women, 11.6% were found to be anti-HEV positive, with higher prevalence in older age groups, specifically those over 35 years.
- The in-house ELISA showed comparable sensitivity and specificity to commercial tests, making it a promising tool for HEV screening in resource-limited settings, especially for public health initiatives.
Aim: This study aimed to assess the effect of COVID-19 on hepatitis-related services in Bangladesh and compared the situation with same study conducted in Japan and globally.
Methods: We conducted an online cross-sectional questionnaire survey among the clinicians of four societies associated with liver disease in Bangladesh from October to December 2022. The questionnaire included the same questions as a survey conducted in Japan and globally.
