Inter- and intra-observer variation in classification systems for impending fractures of bone metastases.

Skeletal Radiology
Moataz El-Husseiny, Nigel Coleman

Abstract

The study was designed to assess the reproducibility and reliability of Mirels' scoring system and the conventional scoring system for impending pathological fractures. The results of both classification systems influence the choice of therapeutic procedures offered to these patients. Eight independent observers (four orthopaedic surgeons and four radiologists with varying clinical experience) scored blinded plain radiographs from 47 patients with bone metastases. Each observer scored the radiographs as per the Mirels and the conventional systems. After 12 weeks, the observers scored the radiographs again. Inter- and intra-observer agreement was assessed based on the weighted kappa coefficient values for both systems. For intra-observer reproducibility, kappa values for the conventional system had a mean of 0.499 (SD 0.074) showing a moderate agreement, while Mirels' scoring system had a mean of 0.396 (SD 0.101) showing a fair agreement. For inter-observer reliability, kappa values for the conventional scoring system were 0.322 for the first test and 0.47 for the second test, giving fair and moderate agreement respectively. For Mirels' scoring system, the kappa coefficient for inter-observer reliability was 0.183 for the first ...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.
