Accuracy of computer algorithms and the human eye in scoring actigraphy.

Sleep & Breathing = Schlaf & Atmung
Kathleen BoyneLee J Brooks

Abstract

The purpose of this study is to determine the optimal scoring method and parameter settings of actigraphy by comparison to simultaneous polysomnography (PSG). Fifteen studies of simultaneous PSG and actigraphy were completed in adolescents (mean age = 16.3 years) and analyzed. Scoring actigraphy by the human eye was compared to a commercial computerized algorithm using various parameters. The PSG was considered the reference standard. There was a better correlation between actigraphy and PSG sleep start/end, total sleep time, wake after sleep onset, and sleep efficiency when the rest period was determined by the human (mean r = 0.640) rather than auto-set by the software (r = 0.406). The best results came when the rest intervals were set based on the PSG (r = 0.694). Scoring the printed actogram by the human eye was superior to the auto analyses as well (r = 0.575). Higher correlations and lower biases were obtained from lower wake threshold settings (low and medium) and higher immobility times (10 and 15 min). Visual scoring by simple inspection of the actigraphy tracing had a reasonable correlation with the gold standard PSG. Accurate determination of the rest interval is important in scoring actigraphy. Scoring actigraphy by...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.
