Abstract

The quantitative measurement of the left ventricle by echocardiography is a fundamental tool in the diagnosis and prognosis of acquired and congenital diseases in the pediatric population. The objective of this study was to validate an automated three-dimensional adaptive analytic echocardiographic algorithm, the so-called Heart Model® (HM) in the pediatric population, using as comparators the left atrial and left ventricular volumes and left ventricular ejection fraction obtained by means of conventional 2D and 3D echocardiography. Pilot study, where a population comprised of 75 consecutive patients aged 6-17 years who attended a pediatric cardiology clinic, was evaluated. Every patient underwent a conventional 2D and 3D echocardiography and an analysis using HM. Conventional 3D echo was used as the reference method. Seventy-five patients were analyzed. Mean age was 11.2 (4.0) years (52.2% women). The intraclass correlation coefficient of HM vs 2D echo was poor, but it was good for the agreement between HM and 3D echo for left ventricular end-diastolic volume (ICC: 0.98; 95% CI: 0.97-0.99; P < 0.001), left ventricular end-systolic volume ICC: 0.98; 95% CI: 0.96-0.99; P = 0.001), and left ventricular ejection fraction (ICC: 0.8...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.
