Abstract

After cardiac surgery, healing can be delayed by sternal wound infection, particularly if mediastinitis develops. Because of the technical simplicity of omentopexy, we recommend the use during open-heart surgery of an omental pedicle graft in selected cases to prevent postoperative complications. This article describes our experience over a 4-month period (from 30 March 1989 through 2 August 1989) with this technique in 50 consecutive patients at moderate-to-high risk for postoperative sternal and mediastinal problems. The patients included 39 men (78%) and 11 women (22%), whose ages ranged from 22 to 83 years (mean, 55 years). Preoperative risk factors included extreme obesity, 13 patients (26%); chronic obstructive pulmonary disease, 13 patients (26%); diabetes mellitus, 6 patients (12%); obesity and diabetes, 8 patients (16%); and obesity, diabetes, and chronic obstructive pulmonary disease, 3 patients (6%). Operative risk factors included cardiac reoperation involving prolonged surgery, 6 patients (12%); bilateral mammary grafting, 17 patients (34%); and the need for prolonged (greater than 72-hour) mechanical respiratory assistance, 2 patients (4%). Three of the 50 patients (6%) were considered to be at moderate risk due 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.
