Febrile reactions occur in around a third of platelet transfusions. Researchers propose that CD40 ligand release from platelets triggers the production of proinflammatory prostaglandin E2, leading to fever. Keeping CD40 ligand levels low before transfusion might reduce adverse events.
Red blood cells play a vital role in storing and releasing nitric oxide, a molecule that regulates blood flow and oxygen delivery. The findings could help improve understanding and treatment of diseases such as diabetes, sickle cell anemia, and high blood pressure.
Researchers have developed a new screening process to detect human parvovirus B19 in blood plasma, ensuring its safety for transfusions. The discovery has already led to improvements in plasma processing and the voluntary recall of contaminated lots.
A new study published in the American Journal of Obstetrics and Gynecology suggests that low-risk women who have had previous cesarean deliveries may benefit from trial of labor, which can reduce maternal fevers and need for transfusion or hysterectomy, while increasing small risk to the baby
A study of caregivers' goals for Alzheimer's treatment reveals that maintaining quality of life is more important than extending lifespan. Most caregivers are willing to accept risks to slow the disease and would prioritize benefits such as preserving memory, communication, and daily function over additional years of life.
The UCSF School of Medicine has developed a radical new curriculum that integrates disciplines, introduces clinical concepts early, and expedites students' entry into patient care. The new model will replace the traditional structure and include courses taught in integrated blocks centered on clinical cases.
A randomized controlled trial found that a new anti-inflammatory drug decreased kidney function at the same rate as an older medication. Prompt treatment with three powerful antiretroviral drugs after HIV exposure prevented infection in a young girl, according to researchers.
A new national study found that unusual infections and fat emboli contribute significantly to acute chest syndrome in sickle cell disease patients. The syndrome is the leading cause of death among sickle cell patients, and earlier diagnosis and treatment may save many lives.
A recent Mayo Clinic study found that patients with CMV disease used significantly more resources and had higher charges than those without infection. Preventive treatment of CMV in high-risk patients can significantly reduce these costs.
The Tuberculosis Research Unit at CWRU will work with seven basic science sites and three clinical sites to evaluate new drugs, vaccines, and diagnostic tests. The unit aims to alleviate the burden of TB, which affects 1.7 billion people worldwide.

This technology can identify infectious agents earlier than current screening tests, reducing the risk of disease transmission through blood products.
The US blood supply is considered extremely safe, with the risk of contracting viruses such as HIV being estimated at one in 676,000. However, a growing aging population will lead to increased demands on the blood supply, resulting in a potential shortage, and more units may need to be imported from abroad.
