Immune checkpoint inhibitors, such as the anti-PD-1 antibody pembrolizumab, have become important tools for managing non-small-cell lung cancer (NSCLC). Assessing the level of programmed death ligand 1 (PD-L1) expressed by a tumor can help clinicians determine how the patient should be treated. A report in The Journal of Molecular Diagnostics describes a novel and rapid approach for quantifying PD-L1 expression levels in tumors that requires only small amounts of tissue that can be collected using minimally-invasive bronchoscopy techniques.

A University of Illinois and Mayo collaboration has demonstrated a novel gene expression analysis technique that can accurately measure levels of RNA quickly and directly from a cancerous tissue sample while preserving the spatial information across the tissue --something that conventional methods cannot do. The team's gene expression technique is described in a paper published in the online edition of Nature Communications.

Chlamydia trachomatis is a bacterium that is one of the most common sexually transmitted infections in Europe. Rates in sexually active young people are commonly between 5% and 10%. The number of diagnosed cases is increasing in many European  countries, in part due to increased testing and the use of more sensitive tests. People with genital chlamydia may experience symptoms of genital tract inflammation including urethritis and cervicitis, but the majority remains asymptomatic.
