The effect of hot beverages, cold beverages, and chewing gum on oral temperature

Transfusion
B H Newman, C A Martin

Abstract

A prospective blood donor's oral temperature is affected by external stimuli such as drinking a hot or cold beverage or chewing gum. These stimuli can cause a deferral or an inappropriate acceptance for a certain unknown time. Ten volunteer subjects were exposed to each of the three stimuli in separate studies. Oral and tympanic membrane temperatures were taken before exposure, immediately after exposure, and at various times until the subject's temperature returned to baseline. The drinking of a hot beverage caused an immediate mean temperature elevation of 2.6 degrees F which would lead to deferral for 7 of 10 subjects. All subjects were acceptable for blood donation (temperature <99.6 degrees F) by 5 minutes. A cold beverage lowered the temperature; the temperature in 6 subjects returned to baseline by 10 minutes and that in 4 did so by 30 minutes. Gum chewing caused minimal temperature elevations; only 1 donor's temperature reached 99.6 degrees F, and it was at acceptable levels for blood donation by 5 minutes. Drinking a hot beverage and, to a much lesser degree, gum chewing can lead to a deferral for elevated temperature, but subjects were acceptable by 5 minutes. Cold beverages are of more concern, because they suppress ...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.
