Abstract

Background and study aims  The benefits of the new-generation CF290 (Olympus, Tokyo, Japan) for pancolonic chromoendoscopy (PCC) for colorectal polyp detection and its procedure time remain questionable. We compared the CF290 with the previous CF260 for PCC. Methods  We performed a propensity score-matching study using baseline characteristics such as age, sex, indications, endoscopist, and bowel preparation. We compared the detection of adenomas and sessile serrated polyps (SSPs) and procedure times of two expert endoscopists who performed PCC using the CF290 series (high-quality system with flushing pump) and the CF260 series (high-definition system). Results  We matched 374 patients who underwent PCC using the CF290 and 187 patients who underwent PCC using the CF260. The adenoma detection rate of the 290 series was higher than that of the 260 series, but not significantly. The SSP detection rate for the 290 series was higher than that for the 260 series ( P  = 0.01). Insertion time required for the 290 series was shorter than that required for the 260 series ( P  < 0.0001). Withdrawal time of the 290 series was shorter than that of the 260 series ( P  < 0.0001). Conclusion  Advanced technology can provide accuracy and help s...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.
