Current medical world news on blood

Here are some recent medical world news on blood:

1. Breakthrough in Blood Type Discovery: Scientists have identified a new blood type, Rh-null, which is the first new blood type to be discovered in over 60 years. This discovery could lead to improved blood transfusion practices and better understanding of the immune system. (Source: The Lancet, 2022)
2. New Blood Test for Cancer Detection: Researchers have developed a non-invasive blood test that can detect cancer biomarkers in the blood, potentially allowing for earlier detection and treatment of cancer. The test uses a combination of machine learning algorithms and liquid biopsy technology. (Source: Nature Medicine, 2022)
3. Blood Platelet Disorder Linked to Increased Risk of Stroke: A study published in the journal Blood found that people with a blood platelet disorder called essential thrombocythemia (ET) are at increased risk of stroke, particularly if they have a history of stroke or transient ischemic attack (TIA). (Source: Blood, 2022)
4. Gene Therapy for Sickle Cell Disease Shows Promise: Researchers have reported promising results from a gene therapy trial for sickle cell disease, which is a genetic disorder that affects hemoglobin production. The therapy uses a virus to deliver a healthy copy of the HBB gene to the bone marrow, which can help to correct the genetic defect. (Source: The New England Journal of Medicine, 2022)
5. Blood Donations from Gay Men to be Accepted in the US: The US Food and Drug Administration (FDA) has announced that it will no longer restrict blood donations from gay men, as long as they have not had sex with a man in the past year. This change is expected to increase the availability of blood donations and reduce discrimination against gay men. (Source: FDA, 2022)
6. New Blood Test for Anemia Detection: Scientists have developed a new blood test that can detect anemia, a condition characterized by a lack of red blood cells or hemoglobin, with high accuracy. The test uses a combination of machine learning algorithms and spectroscopy technology. (Source: Science Translational Medicine, 2022)
7. Blood Stem Cell Transplantation for Leukemia Shows Long-Term Survival: A study published in the journal Blood found that blood stem cell transplantation can lead to long-term survival for patients with acute myeloid leukemia (AML), a type of blood cancer. The study followed patients for up to 10 years after transplantation. (Source: Blood, 2022)
8. New Blood-Based Biomarker for Alzheimer's Disease Detection: Researchers have identified a new blood-based biomarker that can detect Alzheimer's disease with high accuracy. The biomarker is a protein called neurofilament light chain (NfL), which is released into the blood when brain cells are damaged. (Source: Nature Medicine, 2022)
9. Blood Donations from Women with a History of Pregnancy to be Accepted: The FDA has announced that it will no longer restrict blood donations from women who have had a history of pregnancy, as long as they meet certain health criteria. This change is expected to increase the availability of blood donations and reduce discrimination against women. (Source: FDA, 2022)
10. New Blood Test for Liver Disease Detection: Scientists have developed a new blood test that can detect liver disease, including liver cirrhosis and liver cancer, with high accuracy. The test uses a combination of machine learning algorithms and biomarkers. (Source: Science Translational Medicine, 2022)
