Tracheostomy Following Liver Transplantation

Transplantation Proceedings

Abstract

With increased demand for liver transplantation, sicker patients are being transplanted frequently. These patients are at a higher risk of significant postoperative morbidity, including respiratory failure. This study evaluated the phenotype that characterizes liver transplant candidates who may benefit from early tracheostomy. A single center retrospective review of all liver transplant candidates between January 2012 and December 2017. Patients who eventually required tracheostomies were identified and compared to their counterparts. Of the 130 liver transplants performed during the study period, 11 patients required tracheostomy. Although patients in the tracheostomized population (TP) did not have significantly worse preoperative functional status (<4 metabolic equivalents; 64% vs 42%, P = .21), they had a higher native model for end-stage liver disease (MELD) score (37 vs 30, P < .05) at the time of transplantation. Patients who eventually succumbed to respiratory failure had lower arterial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2) ratios at the start of surgery and remained unchanged for the duration of surgery compared with the nontracheostomy group (P < .05). TP patients required more net fluid intraope...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.
