Abstract

Objective. The total relative value unit (TRVU) of surgery reflects surgical complexity. However, its impact on mortality after noncardiac surgery has not been identified. This study aimed to investigate the association of TRVUs for surgery with postoperative 90-day mortality in adult patients who received planned, elective noncardiac surgery. We hypothesized that higher TRVU was associated with an increase in 90-day mortality after noncardiac surgery. Method. This retrospective cohort study analyzed medical records of adult patients admitted to a single tertiary academic hospital between January 2012 and December 2018 for planned elective noncardiac surgery. The primary end point was 90-day mortality. Results. A total of 112 606 patients were included. Among them, 561 patients (.5%) exhibited mortality within 90-days. In the multivariable model, an increase of 10 000 points of TRVUs was not significantly associated with 90-day mortality (odds ratio: .98, 95% confidence interval: .93 to 1.04; P = .536). Additionally, when it was divided into 4 quartile groups (Q1, Q2, Q3, and Q4), Q2, Q3, and Q4 group of TRVUs were not associated with 90-day mortality compared to the Q1 group of TRVUs (P = .058, .984, and .237, respectively).

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.
