Abstract

Using a simple and intuitive method, we evaluated changes in the dimensions of the thoracic cavity of pectus excavatum (PE) patients following the Nuss procedure. We performed a retrospective review of 141 patients who had undergone the Nuss procedure. The thoracic cavity was visualized using computed tomography (CT) scans and its dimensions determined by measuring the anteroposterior (AP) and transverse (T) diameters at three anatomical landmarks (the jugular notch, and manubriosternal and xiphisternal joints). The Wilcoxon signed-rank test was used to compare differences between preoperative and postoperative parameters. Kruskal-Wallis tests were performed to compare differences among groups in patient age, type of PE, and number of inserted bars. Of the 141 patients (115 men, 26 women), 87 had symmetric and 54 had asymmetric defects. The postoperative AP diameters at the manubriosternal and xiphisternal joints were significantly higher than their preoperative values, whereas the Haller indices and T diameters at the three anatomical landmarks were significantly lower than their preoperative values. In the multiple bars group, the postoperative AP diameters increased significantly compared with their preoperative values. In t...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.
