Closing the gap: Finding undiagnosed hepatitis C infections after blood transfusions

What is the incidence of viral hepatitis caused by blood transfusions before and after Sweden introduced screening of blood in the early 1990s?

PulseCam peeks below skin to map blood flow

Rice University engineers have found a way to use a video camera to peek below the skin and make high-resolution maps that show doctors and nurses exactly how much blood is reaching the capillaries. PulseCam uses a patented process to combine information from video recordings and a pulse oximeter to create high-resolution blood perfusion maps. Blood flows from the heart […]

Australian study: Many home blood pressure monitors not validated for accuracy

Most blood pressure devices sold for home monitoring in Australia—and possibly worldwide—may not have been validated for accuracy and could lead to misdiagnoses and inappropriate treatment, according to new research published today in Hypertension, an American Heart Association journal. In this study, the researchers studied the online blood pressure device marketplace in Australia, including large, multi-national, e-commerce businesses such as […]

Spikes in blood pressure among young adults spell trouble in mid-age

Wide swings in blood pressure readings among young adults are associated with a higher risk of cardiovascular disease by middle age, a new analysis led by Duke Health researchers shows. The finding, publishing Jan. 22 in JAMA Cardiology, suggests that the current practice of averaging blood pressure readings to determine whether medications are necessary could be masking a potential early […]

Blood-clotting protein and blood platelets promote immune evasion, cancer progression

A new study led by researchers at The Ohio State University Comprehensive Cancer Center—Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC—James) reveals how a clotting protein and blood platelets can promote cancer progression and suppress immune responses to cancer. The findings show how thrombin, a clotting protein in the blood, causes blood platelets to release transforming […]

Blood test can quickly match advanced breast cancer patients to targeted treatments

A blood test can help identify rare mutations in advanced breast cancer, which may enable patients to access effective treatments more quickly in the future, Cancer Research UK scientists have found. As part of the plasmaMATCH clinical trial, funded by Stand Up To Cancer, a joint fundraising campaign from Cancer Research UK and Channel 4, the researchers were able to […]
