Study shows that HEALTHROUNDS-Platelets are best stored chilled for several weeks and not just a few days.

We also share data that confirms the high cancer risk for U.S. airline crews from cosmic radiation.

AVAILABILITY OF CHILLING PLATELETS MAY BE EXPANDED SAFELY

Researchers who have tested the use of refrigerated plates say that their results could help more than triple the?supply? available to save bleeding patients.

Platelets are an important blood component for clotting. They also help to stop blood loss. Platelets donated are stored at room temperatures with a shelf life of five to seven days.

In 27 hospitals across the U.S., Australia and Canada, 1,000 children and adults who underwent cardiac surgery were given either chilled platelets or room-temperature plates that had been stored for no more than seven days.

Researchers reported in JAMA that platelets stored at room temperature for three weeks or longer were equally effective as those kept refrigerated.

Researchers noted that a significant portion of the 2.5 millions room temperature platelet units collected in the U.S. each year are wasted because they have a short shelf-life.

In a press release, Dr. Philip Spinella of University of Pittsburgh stated that the new findings would "dramatically improve the availability of blood platelets and reduce waste." This will allow hospitals outside of major cities to be able to afford this life-saving product for bleeding patients.

His team pointed out that rural and community hospitals cannot currently justify stocking room temperature platelets because they do not often treat patients with severe bleeding.

Researchers said that their results were already being reviewed by the U.S. FDA and regulators from other countries.

OCCUPATIONAL Radiation HITS U.S. Airline crews are the hardest hit

Researchers say that in a large survey of U.S. workers flight attendants, pilots, and other aviation professionals had the highest percentage of cancer-related deaths due to occupational radiation.

Researchers reported in JAMA Internal Medicine that even nuclear medicine technologists who are regularly exposed to radiation had lower mortality rates for these cancers than flight crews and cabin crews.

The National Vital Statistics System was used to analyze death certificates from more than 13 million people across 503 professions between 2020 and 2024, including 14,000 pilots and approximately 7,000 flight attendants.

The researchers looked for deaths caused by radiation-related cancers in the breast, blood, thyroid gland, skin, and central nervous system.

Researchers found that after accounting for individual factors, pilots and flight attendants have statistically higher rates of dying from cancers such as breast, prostate, central nervous system, and melanoma.

Leukemia death rates were also higher among pilots.

Radiation-related cancers caused 6.9% of all deaths in flight attendants, and 6.7% among pilots.

Flight crew members were not at higher risk for non-radiation-related cancer deaths.

According to a report, pilots and flight attendants accumulate 3 to 6 millisieverts of cosmic radiation per year, which is much higher than the 0.4 millisieverts that an air traveler who takes 10 round-trips across the country per year would receive.

Unlike other?U.S. workers, these workers are not subjected to federal dose limits or monitor requirements despite the fact that they are recognized by the U.S. Federal Aviation Administration as being occupationally exposed. Researchers noted that radiation-exposed aircrew or workers in other countries.

Researchers who were not involved with the study wrote an editorial that the findings "...should be of interest to policymakers, airline regulators, and 'clinicians caring for those who work at high altitudes.

The editorial suggests that doctors have a "heightened index of suspicion" in evaluating any aircrew who may be suffering from cancer. Sign up for the newsletter to receive it in your mailbox. (Reporting and editing by Aurora Ellis; Reporting by Nancy Lapid)
