Abstract

We sought to assess interrater reliability (IRR) of lung point-of-care ultrasound (POCUS) findings among pediatric patients with suspected pneumonia. A convenience sample of patients between the ages of 6 months and 18 years with a clinical suspicion of pneumonia had a lung ultrasound performed by a POCUS-credentialed emergency medicine physician with subsequent expert review. Each lung zone was assessed as either normal or abnormal, and specific ultrasound findings were recorded. IRR was assessed by intraclass correlation coefficient (ICC) and kappa statistics. Seventy-one patients, with a total of 852 lung zones imaged, were included. The sonographer assessment of normal versus abnormal, across each of the zones, demonstrated moderate agreement with ICC 0.46 (95% CI: 0.41, 0.52) and kappa 0.56. Right-sided zones demonstrated moderate agreement [0.43 (CI 0.35, 0.51)] while left-sided zones, specifically left-sided anterior zones, showed only fair agreement [0.36 (0.28, 0.44)]. IRR varied between specific findings: ICC for B-lines 0.52 (95% CI: 0.46, 0.57), pleural effusion 0.40 (0.34, 0.45), consolidation 0.39 (0.33, 0.44), subpleural consolidation 0.31 (0.25, 0.37), and pleural line irregularity 0.16 (0.10, 0.23).

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.
