Abstract

This study aimed to evaluate the influence of prior knowledge of human papillomavirus (HPV) status in cervical cytopathology readings. Participants comprised 2,376 women who underwent parallel cytology and HPV-DNA testing. Smears were read twice by the same team, first with previous knowledge of HPV-DNA status. Overall, 239 (10.2%) smears had their cytology classification altered by the HPV-informed review. Cytology readings with prior knowledge of the HPV status revealed 10.5% of abnormal smears (atypical squamous cells of undetermined significance or higher), while without prior knowledge, this rate dropped to 7.6%. When HPV status was informed, a significant increase in all categories of altered smears was observed. Cytology with prior knowledge of HPV status detected more cervical intraepithelial neoplasia grade 2 or higher (CIN 2+) compared with blinded: 86.7% vs 60.0%. Our data indicate that cytology interpreted with prior knowledge of the HPV status provides higher sensitivity for CIN 2+ lesions while marginally reducing the overall specificity compared with HPV status blinded cytology.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
