Researchers discover why people with sickle cell disease get milder cases of malaria

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells.

Tranexamic acid reduces bleeding in off-pump coronary bypass surgery

Patients undergoing off-pump coronary artery bypass grafting who are given a tranexamic acid infusion show a modest reduction in postoperative bleeding and blood transfusion relative to their placebo-treated peers, a clinical trial shows.

Anemia prevention in pregnancy: an interview with Juan Pablo Peña-Rosas, WHO

Anaemia is a condition in which the number of red blood cells in the body is lower than normal or these have lower amounts of haemoglobin, a protein that is involved in the oxygen exchange of the body.

DNA inherited from mother can speed up male ageing

Women outlive men by about five to six years but why? By age 85 there are roughly six women to every four men and by age 100 the ratio is more than two to one.

Sickle cell trait link with sudden athlete death ‘confirmed’

Researchers say they have definitively confirmed that there is a link between the sickle cell trait and sudden cardiac death in African–American athletes.

Scientists decode stability blueprint of rhomboid enzyme

Johns Hopkins scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function.

RBC transfusion use in neonates requires more study

Results from a systematic review indicate that the safety and efficacy of red blood cell transfusions in neonates is currently unclear and requires more precise study.

Malaria misdiagnosis: an interview with Dr Toby Leslie

Malaria is caused by a multi-staged parasite which is transmitted by the bite of infected female anopheles mosquitoes. It affects millions of people and kills more than 500,000 people throughout the world every year.

HemoGlobe device can identify women with anemia

Could a low-cost screening device connected to a cell phone save thousands of women and children from anemia-related deaths and disabilities? That's the goal of Johns Hopkins biomedical engineering undergraduates who've developed a noninvasive way to identify women with this dangerous blood disorder in developing nations. The device, HemoGlobe, is designed to convert the existing cell phones of health workers into a "prick-free" system for detecting and reporting anemia at the community level.

Researchers uncover protein structure that regulates blood cell formation and activity

A Finnish research team together with researchers from New York, USA, has uncovered a protein structure that regulates cell signalling and the formation of blood cells. The team's results, published in Nature Structural & Molecular Biology, the most prestigious journal in the field, shed light on the mechanisms at play in haematological disorders and provide new opportunities for the design of disease-specific treatment.

Scientists identify inhibitors of key enzyme involved in survival of malaria parasite

An international team of scientists, led by researchers from the Department of Pediatrics at the University of California, San Diego School of Medicine, have identified the first reported inhibitors of a key enzyme involved in survival of the parasite responsible for malaria. Their findings, which may provide the basis for anti-malarial drug development, are currently published in the online version of the Journal of Medicinal Chemistry.

Normalizing weight helps girls with eating disorders improve essential fatty acid status

A study of teenage girls with eating disorders has shown that reduced essential fatty acid levels returned to normal once the girls increased their weight to a healthy level.

Two cellular proteins team up to provide steady supply of RBCs

Two cellular proteins team up to provide a steady supply of red blood cells (RBCs), according to a study by Lizhao Wu, PhD, of the University of Medicine and Dentistry of New Jersey-New Jersey Medical School, and colleagues.

Eltrombopag can raise blood cell levels in some people with severe aplastic anemia

Eltrombopag, a drug that was designed to stimulate production of platelets from the bone marrow and thereby improve blood clotting, can raise blood cell levels in some people with severe aplastic anemia who have failed all standard therapies.

Treating Sickle Cell Disease with L-Glutamine

By focusing on how best to help patients, researchers can sometimes find solutions that are much simpler than anticipated. That has been the guiding approach to our efforts to develop a treatment for sickle cell disease.

Researchers design microparticles that can deliver oxygen quickly into the bloodstream

Patients unable to breathe because of acute lung failure or an obstructed airway need another way to get oxygen to their blood—and fast—to avoid cardiac arrest and brain injury. A team led by researchers at Boston Children's Hospital has designed tiny, gas-filled microparticles that can be injected directly into the bloodstream to quickly oxygenate the blood.

Postoperative hemoglobin predicts hospital stay after hip fracture surgery

Postoperative anemia is associated with longer hospital stays following surgery for hip fracture, Dutch researchers report.

Deferasirox reduces elevated iron levels in patients with myelodysplastic syndrome

Researchers at Moffitt Cancer Center and colleagues at six other institutions have recently tested a treatment for patients with myelodysplastic syndrome, or MDS, a blood-related malignancy that involves the ineffective production of blood cells, leaving patients anemic and in need of frequent blood transfusions. Because the body has no natural means to reduce iron that accumulates from repeated transfusions, patients' organs can become iron overloaded, leading to heart failure, liver injury, susceptibility to infection, and other complications.

CARHY announces comprehensive hematopoietic stem cell transplant service

Adding an impetus to the already existing image of Bangalore being a healthcare destination of India, Columbia Asia Referral Hospital, Yeshwanthpur (CARHY), announced comprehensive bone marrow transplant (stem cell transplant) service on Thursday.
