A new survey reveals that fewer than 3% of US sickle cell patients receive red blood cell exchange therapy, despite 91% of providers having access to the technology. Barriers include insurance coverage, limited donor blood, and a lack of specialized centers, particularly in rural areas.
A Lancet review explores whether amyloid-beta pathology linked to Alzheimer’s could spread via blood transfusions. While not proven, prior work hints at transferable amyloid via medical procedures, and a 2023 Danish-Swedish study found recipients of transfusions from donors who later developed brain bleeds had higher recurrence risk, a clue connected to cerebral amyloid angiopathy. Experts urge caution, noting insufficient data to quantify risk, but advocate large-scale epidemiological studies and potential safeguards (donor biomarker screening, enhanced monitoring for high-risk patients). The UK infected blood inquiry is cited as a cautionary example of delaying safety measures, underscoring the need for transparency and preparedness.
UK and Israel researchers have identified a new human blood group system, MAL, tied to the AnWj antigen absent in a 1972 patient and missing in some individuals due to MAL gene mutations. The discovery, published in Blood in 2024, shows that AnWj-negative status can arise from mutations or, in some cases, antigen suppression. By confirming the MAL gene as the culprit, scientists can test for inheritance or underlying medical issues, improving care for rare transfusion patients.
A Scottish court has authorized a blood transfusion for a 14-year-old Jehovah's Witness girl in an emergency, despite her religious refusal, considering her capacity and the potential severity of not administering the transfusion.
Scientists have identified a new human blood group system called the MAL blood group, after discovering a patient from 1972 lacked a surface molecule found on all other red blood cells, a finding that could improve transfusion safety for rare blood types.
Maegan Clay's father was infected with hepatitis C through contaminated NHS blood products in the 1980s, a revelation that came too late to save his life and deeply affected their relationship. The scandal, involving thousands of victims, has led to a government inquiry, compensation schemes, and ongoing calls for justice and acknowledgment for those affected.
Scientists have discovered that young blood serum, when combined with bone marrow cells, can activate anti-aging signals in human skin cells, potentially reversing signs of aging by promoting cell renewal and collagen production. This research, conducted using a 3D human skin model, highlights the role of specific proteins in this process and suggests promising avenues for future anti-aging therapies, although further testing in humans is needed.
Chad Michael Murray revealed he nearly died at age 15 after losing 50% of his blood due to internal bleeding, which required extensive surgery and a blood transfusion, leading him to adopt a healthier lifestyle to avoid future health issues.
Scientists discovered a new, unique blood type called 'Gwada negative' in a woman from Guadeloupe, which is genetically distinct and may help improve care for patients with rare blood types. The discovery was made using advanced gene sequencing, revealing a mutation in the PIGZ gene that makes her compatible only with herself. Researchers aim to find more individuals with this blood type, especially among local blood donors.
French scientists have identified a new blood type called 'Gwada negative' in a woman from Guadeloupe, making it the 48th recognized blood group system worldwide, which could improve care for patients with rare blood types.
Japanese scientists have developed an artificial blood made from hemoglobin extracted from expired donor blood, encased in a protective shell, which can be stored longer and used universally without compatibility testing, aiming to address blood supply shortages and potentially be in practical use by 2030.
Former NFL player Steve "Mongo" McMichael, who is battling ALS, underwent a blood transfusion after developing MRSA and a urinary tract infection. The Hall of Famer, scheduled to be inducted in August, was admitted to intensive care but is responding to treatment and expected to be released soon. He had previously been hospitalized in 2023 with sepsis and pneumonia.
Former Chicago Bears player Steve ‘Mongo’ McMichael, who was diagnosed with ALS in 2021, has been hospitalized with a urinary tract infection and is now receiving a blood transfusion for MRSA, a difficult-to-treat staph infection. His family has requested prayers for his recovery. Despite his health challenges, McMichael was announced as a member of the 2024 NFL Hall of Fame class in February.
A study supported by the National Institutes of Health suggests that umbilical cord milking, a procedure that involves gently squeezing the cord to push blood into a preterm infant's abdomen, appears to be safe for infants born after 28 weeks. The technique allows for faster response than the standard procedure of delayed cord clamping, reducing the delay for infants in need of immediate assistance. The study found that rates of severe brain bleeding and/or death did not differ significantly between infants who underwent cord milking and those who underwent delayed cord clamping.
Rock star Bret Michaels has adopted a stray husky named Bret Michaels after the dog saved a month-old kitten's life through a blood transfusion. The Nebraska Humane Society shared the story on Facebook, which reached the attention of the human Bret Michaels. The rock star, who is a dog lover, reached out to the shelter and expressed his interest in adopting the husky. The dog, who was found as a stray, now has a new home with the rock star, who plans to meet him in person after his tour.
