Abstract

The aim of this study was to evaluate the quality of the Finnish mammography programme by assessing process indicators from 10 screening centres using data from the first and subsequent screens. We compared these screen-specific indicators with European standards and results from countries with similar screening protocols. Ten Finnish centres invited approximately 1,000,000 women from 1991-2000. Women were mainly 50-64 years old. Mean compliance amongst this age group was 90% at the first and 93% at subsequent screens. The corresponding recall rates were 4.6% and 2.3%, respectively. The average breast cancer detection rates were 0.44% and 0.36%, respectively. The positive predictive values (PPVs) of mammography at the first and subsequent screens were 10% (range 7-20%) and 16% (range 12-31%), and the corresponding benign to malignant (B:M) biopsy ratios were 1:1 (range 0.5-1.8:1) and 0.4:1 (range 0.3-0.8:1). The PPV of mammography increased significantly during the study period, and the average process indicators fulfilled the criteria of the European community for the most part. However, the variation in PPVs was wide, as has been seen for other European mammography programmes, indicating meaningful differences in diagnostic c...Continue Reading

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.
