Abstract

Early tracheal extubation has been the focus of recent attempts to accelerate the care of patients after aortocoronary bypass. Following the 1994 validation of a preoperative mortality risk mode based on the Society of Thoracic Surgeons National Cardiac Surgery Database, we examined the records of 328 aortocoronary bypass patients from our institution and identified 133 patients with low preoperative mortality risk. Their records were then analyzed for duration of tracheal intubation. One low-risk patient who did not survive was excluded from the analysis. Of the remaining 132 patients, 108 experienced no postoperative complications; nevertheless, 50 of these were intubated longer than 10 hours despite freedom from complications. In a 2nd group of 153 consecutive low-risk patients, we prospectively implemented a patient care protocol that designated low-risk patients as eligible for accelerated weaning. Compared were the 1st group, these patients with low preoperative mortality risk were weaned from mechanical ventilation in 40% less time. Thus, we found that low preoperative mortality risk predicts success in early tracheal extubation. Risk stratification appears to be a simple and useful means of identifying patients least li...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.
