Article Synopsis
- Social network-based data collection methods are useful for measuring abortion rates in restrictive environments, but they need to consider how visible abortions are within social networks to avoid bias.
- This study explores using respondent-driven sampling (RDS) and the game of contacts method in Uganda and Ethiopia to assess abortion visibility and test potential biases.
- While some promising results were found, challenges like sample representativeness and knowledge transfer methods may have affected the estimates, leading to recommendations for improving the methodology.
Article Synopsis
- A study in Buenos Aires, Argentina, found a 4.2% prevalence of Hepatitis D virus (HDV) among hepatitis B virus-reactive patients, with many of these cases being nonreactive to standard anti-HDV antibodies.
- The research involved analyzing 189 serum samples, revealing that most HDV RNA cases were undetected by typical diagnostic methods, suggesting a need for improved testing.
- The findings highlight the importance of synchronous testing for better diagnosis of HDV and call for further studies to target high-risk populations and enhance prevention strategies for co-infections.
Lung transplant recipients (LTRs) respond poorly to vaccination. SARS-CoV-2 pre-exposure prophylaxis (PrEP) with tixagevimab/cilgavimab (TIX/CIL) reduces the incidence of infection and the evolution to severe COVID-19. In vitro data show decreased activity against Omicron variants.

Purpose: This interlaboratory comparison was conducted to evaluate the performance of the Latin-American Biodosimetry Network (LBDNet) in analyzing digitized images for scoring dicentric chromosomes from irradiated blood samples. The exercise also assessed the use of weighted robust algorithms to compensate the uneven expertise among the participating laboratories.
Methods: Three sets of coded images obtained through the dicentric chromosome assay from blood samples irradiated at 1.
