A small study of 25 patients with hereditary hemorrhagic telangiectasia found improved cardiac output and reduced duration and number of episodes of nose bleeds after receiving bevacizumab. The treatment also significantly improved quality of life, with moderate toxicity observed.
The National Institutes of Health has signed a research and development agreement with two non-profit organizations to develop potential clinical therapies for rare blood cancers. The collaboration aims to bridge the gap between basic research and human testing, with the goal of accelerating the delivery of improved therapies to patients.
Researchers found that N-acetylcysteine reduces the size and activity of von Willebrand factor multimers in human plasma and mice, offering a potential rapid treatment for patients with TTP. The study suggests that this approach could be effective in reducing complications associated with current treatments.
A study has revealed a relationship between blood cells and their stem cell 'parents', influencing gene expression and behavior. The discovery opens up new research avenues into diseases caused by stem cell disorders.
Researchers from Massachusetts General Hospital are leading teams to develop stem-cell-based models of cardiovascular and blood disorders. The NHLBI grants will support the development of regenerative therapies for heart failure and other disorders.
Researchers analyzed 17,398 patient records and found only 14 real disease associations with MGUS, not 61 as previously reported. This finding may reduce unnecessary testing and treatment for patients with MGUS.
A study found that miR-143 and miR-145 regulate the contractile nature of vascular smooth muscle cells, with their absence leading to increased tissue matrix production and signs of blood vessel disease. The findings suggest these microRNAs could serve as therapeutic targets for enhancing blood vessel repair.
Researchers identified a common genetic sequence alteration that enhances the likelihood of acquiring a mutation in a gene linked to certain blood diseases. Patients with myeloproliferative neoplasms have a higher risk of developing another JAK2 mutation due to inherited DNA sequence changes.
Researchers at Yale School of Medicine developed a man-made anti-clotting protein that prevents excessive clotting in patients with hereditary antithrombin deficiency. The treatment showed no adverse effects during treatment or seven days after treatment, indicating its potential to prevent complications linked to the condition.
The American Society of Hematology has launched an initiative to provide increased support for training programs in hematology-related disciplines. Three grant recipients will develop new curricula that integrate emerging technologies into traditional training programs, addressing the need for clinicians and clinical researchers with s...
International health experts call for urgent action from international development banks and pharmaceutical companies to address blood pressure-related diseases affecting developing countries. The authors argue that deaths from heart disease and stroke are largely avoidable but lack of effort has resulted in over 50 million deaths, wit...
The NHLBI-funded program aims to translate knowledge into clinical practice for treating heart, lung, and blood diseases. It focuses on repairing damaged heart muscle, reducing immune complications, and enhancing adult stem cell interactions.
