Abstract

Computed tomography (CT) scans have become imaging modalities of choice in trauma centers. The purposes of this study were to evaluate the trend of radiation exposure in acute trauma patients. Our hypothesis was that radiation dosage and charges would increase over time without change in patient acuity or outcome. Five hundred consecutive trauma patients were retrospectively reviewed for the years 2002, 2005, and 2008. Total number of CT scans, plain radiographs, and total radiation dosage (milliSieverts [mSV]) were determined. Charges were calculated. Injury severity scores and mortality were determined. The mean number of CT scans for category 1 patients in 2002, 2005, and 2008 was 1.5, 3.1, and 4.6, respectively (p = 0.01). This trend was similar in category 2 patients: 2.0, 3.5, 5.1, respectively (p < 0.01). Significant decreases in plain radiography were noted concurrently. This contributed to increased total radiation exposure to categories 1 and 2 patients over 2002, 2005, and 2008: 12.0 mSV, 23.6 mSV, and 33.6 mSV (p = 0.02); and 17.5 mSV, 24.1 mSV, and 37.5 mSV (p < 0.001), respectively. Charges for diagnostic imaging per patient also increased for categories 1 and 2 patients over 2002, 2005, and 2008: $2,933, $4,656, ...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.
