The National Institutes of Health (NIH) is funding Canadian component of a study to determine the optimal amount of blood to transfuse in anemic patients who have suffered a myocardial infarction.
Researchers have found iron deficiency anemia protects children against the blood-stage of Plasmodium falciparum malaria in Africa, and treating anemia with iron supplementation removes this protective effect.
A life-threatening infection in an infant with leukemia led to a St. Jude Children’s Research Hospital discovery of how prolonged infection sets the stage for bacterial persistence despite antibiotic susceptibility.
Cincinnati Children’s researchers report in Nature Immunology a new mechanism that controls blood cell function and several possible molecular targets for treating myelodysplasia syndromes (MDS) – a group of pre-malignant disorders in which bone marrow does not produce enough healthy blood cells. MDS can lead to acute myeloid leukemia (AML), a fast-spreading blood cancer that can be deadly if not treated promptly.
Researchers are working to develop a pill to treat this serious inherited bleeding disorder. Oral delivery of the treatment--clotting factor IX--would allow individuals with type B hemophilia to swallow a pill rather than be subjected to several weekly injections of factor IX to control potentially fatal bleeding episodes.
The detection of prions in the blood of patients with variant Creutzfeldt-Jakob disease could lead to a noninvasive diagnosis prior to symptoms and a way to identify prion contamination of the donated blood supply, according to researchers at McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth).
Modeling blood flow through a stent graft put graduate student John Asiruwa on the path to a career in biomedical engineering, doing work that “can be life changing for patients.”
Saint Louis University scientist Angel Baldan, Ph.D., reports that turning off a protein found in liver and adipose tissue significantly improves blood sugar levels and reduces body fat in an animal model.
Researchers found that patients whose oropharyngeal cancer recurred had higher levels of antibodies for two proteins, E6 and E7, which are found in HPV-fueled cancers. The finding suggests a potential blood-based marker that could predict when cancer is likely to return.
Researchers have found that a Chinese herbal regimen called TSY-1 (Tianshengyuan-1) TSY-1 increased Telomerase activity in normal blood cells but decreased it in cancer cells. Telomerase is an enzyme responsible for the production of telomeres, which play an important role in the regulation of normal cell division. These results indicate that Telomerase-based treatments may be of significance in treatments for both blood cell deficiency and cancer.

University of Warwick is collaborating with researchers at the NIHR Surgical Reconstruction and Microbiology Research Centre (SRMRC) to support a ground-breaking new study to investigate the effectiveness of giving patients blood products immediately after a major injury or trauma - before they reach hospital.
A personalized cancer vaccine markedly improved outcomes for patients suffering from acute myeloid leukemia (AML), a potentially lethal blood cancer, in a clinical trial led by investigators at Beth Israel Deaconess Medical Center (BIDMC). The product of a long-term collaboration among investigators at the Cancer Center at BIDMC and Dana-Farber Cancer Institute, the vaccine stimulated powerful immune responses against AML cells and resulted in protection from relapse in a majority of patients, the team of researchers reported today in Science Translational Medicine.
Magnets instead of antibiotics could provide a possible new treatment method for blood infection. This involves the blood of patients being mixed with magnetic iron particles, which bind the bacteria to them after which they are removed from the blood using magnets. The initial laboratory tests at Empa in St. Gallen have been successful, and seem promising.
The blood-brain barrier is a network of specialized cells that surrounds the arteries and veins within the brain. It forms a unique gateway that both provides brain cells with the nutrients they require and protects them from potentially harmful compounds. An interdisciplinary team of researchers from the Vanderbilt Institute for Integrative Biosystems Research and Education (VIIBRE) headed by Gordon A.
Results of a new study led by Johns Hopkins researchers offer new evidence for a strong link between angiotensin receptor autoantibodies and increased risk of frailty. In a report on the work, published online in the journal Circulation on Nov. 30, the team says a large class of common blood pressure drugs that target the angiotensin receptor, called angiotensin receptor blockers (ARBs), may help patients depending on the levels of the autoantibodies.
Analysis of a phase 3 trial shows that older patients with high-risk or secondary AML, who received initial treatment with CPX-351, had improved survival following allogeneic hematopoietic cell transplant, when compared with patients who received standard 7+3 cytarabine and daunorubicin as initial therapy.
Patients with myelodysplastic syndromes (MDS) suffer from a reduction in the number of different types of blood cells, including red blood cells leading to the development of anemia. Many patients with lower-risk MDS benefit from treatment with recombinant-erythropoietin (rHuEPO), which stimulates blood cell production.
As the Zika epidemic spreads to the United States, the potential for contracting the disease via blood transfusion has emerged as a serious concern. The problem of transfusion-related Zika virus transmission—and recommended strategies to reduce that risk—are outlined in a special article in Anesthesia & Analgesia. Anesthesia & Analgesia is published by Wolters Kluwer.
Whether patients with mechanical heart valves or left ventricular assist devices must take blood thinners depends on how effectively blood flows through these implantable devices. Researchers have modeled the flow of blood through these devices to estimate clotting risk, but this type of work has not been done on stent grafts—until now. The results showed that shear accumulation in a new endovascular stent graft design was comparable to that of an idealized aorta.
• New research estimates the projected lives that would be saved if patients at high risk of cardiovascular disease underwent intensive blood pressure lowering.
• The findings will be presented at ASN Kidney Week 2016 November 15–20 at McCormick Place in Chicago, IL.
Carrying extra weight increases a person's risk that a benign blood disorder will develop into multiple myeloma, a blood cancer. This is particularly true for older, African-American men.
Roughly 86 million Americans have prediabetes, and the vast majority of them don’t even know they have it. But the progression from prediabetes to type 2 diabetes is not inevitable, and there’s a simple blood test that can determine whether a person’s blood glucose levels need attention.
Freezing and reanimating your body is still science fiction, but cryopreserving cells and certain tissues for future use is a reality. Still, the process could use some improvements to make it more useful in emergencies. In a recent study in the journal ACS Omega, scientists take a close look at a new class of small molecules with the potential to make the process more practical and give the cells and tissues a longer shelf life.
A new study led by scientists at The Scripps Research Institute (TSRI) reveals that a protein first discovered at TSRI in 2010 is directly responsible for sensing touch.
A new treatment may diminish a dangerous side effect associated with transfusions of red blood cells (RBCs) known as pulmonary hypertension, an elevated blood pressure in the lungs and heart that can lead to heart failure, suggests a new study published in the November issue of Anesthesiology.
Zinc is essential for wound healing, for vision, for DNA creation, for our senses of taste and smell, even for sexual health. But despite its importance, scientists have never fully understood the mechanism that moves the mineral through the body – until now. Researchers have, for the first time, created detailed blueprints of the molecular moving vans that ferry this important mineral everywhere it’s needed through the blood.
A half billion dollars – at least -- gets spent each year on blood tests to see which hospital patients have a genetic quirk that makes their blood more likely to form dangerous clots. And most of that spending probably isn’t necessary, a new review shows.
Incapacitating specific nerves to the kidneys improves the work of insulin on another organ, the liver, according to research from Cedars-Sinai recently published in the journal Diabetes.
Researchers with the UCI Susan Samueli Center for Integrative Medicine have found that regular electroacupunture treatment can lower hypertension by increasing the release of a kind of opioid in the brainstem region that controls blood pressure.
A newly published study of people with chronic obstructive pulmonary disease (COPD) concludes that long-term supplemental oxygen treatment results in little or no change in time to death, time to first hospitalizations or significant quality of life improvements for those with moderately low blood oxygen levels.
The Canadian Patent Office awarded Streck a patent regarding its Cell-Free DNA BCT®, a direct-draw blood collection tube that stabilizes nucleated blood cells.

St. Jude Children’s Research Hospital – Washington University Pediatric Cancer Genome Project team identifies genetic changes underlying a type of B-precursor acute lymphoblastic leukemia
It’s been long thought that when blood transfusions are needed, it may be best to use the freshest blood, but McMaster University researchers have led a large international study proving that it is not so.
In efforts to develop new treatments for brain cancer, scientists from Johns Hopkins Drug Discovery and the Kimmel Cancer Center's Bloomberg~Kimmel Institute for Cancer Immunotherapy report they have altered the structure of an experimental drug that seems to enhance its ability to slip through the mostly impermeable blood-brain barrier.
Hematology researchers have found that blocking the role of a common protein may offer unexpected benefits for patients with the inherited bleeding disorder hemophilia A. The finding offers potential for developing both gene therapy and more effective protein replacement treatments for hemophilia A, the most common form of hemophilia.
A team of physicians and laboratory scientists has taken a key step toward a cure for sickle cell disease, using CRISPR-Cas9 gene editing to fix the mutated gene responsible for the disease in stem cells from the blood of affected patients. For the first time, they have corrected the mutation in a proportion of stem cells that is high enough to produce a substantial benefit in sickle cell patients.
For most stable hospitalized patients, transfusions of red blood cells stored for any time point within their licensed dating period — so-called standard issue — are as safe as transfusions with blood stored 10 days or less, or “fresh,” according to updated clinical guidelines issued by an expert panel convened by a national organization that has long set standards for blood banking and transfusion practices.
