Connecting dots between higher blood pressure early in life and dementia

Whether elevated blood pressure early in life translates to increased risk of dementia is a question scientists are working to answer. “Dementia is not a normal part of aging, and once it begins you can’t reverse it,” says Dr. Shaoyong Su, genetic epidemiologist at the Georgia Prevention Institute at the Medical College of Georgia at Augusta University. “It typically surfaces […]

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 […]

Scientists reliably predict people’s age by measuring proteins in blood

The carnival worker who tries to guess your age relies on aspects of your appearance, such as your posture and whether any wrinkles emanate from the corners of your eyes and lips. If the carny’s guess is more than a few years off, you win a stuffed koala. But a team of Stanford University School of Medicine scientists doesn’t need […]

Better way to interpret blood tests to diagnose pulmonary embolism

A study led by Hamilton researchers has found a new way to interpret blood test results in patients who are investigated for blood clots in their lungs, a condition known as pulmonary embolism. This new approach applies to D-dimer blood tests, which are used by physicians to rule out the presence of a blood clot. Researchers found that a higher […]

New migraine medications could endanger patients with high blood pressure

New migraine medications block αCGRP, a neuropeptide which causes vasodilation, for example in the meninges. The very same peptide, which is formed in the muscles during physical activity, protects the heart—which is vital for people with chronic high blood pressure. The innovative migraine prophylaxis could endanger these people, as researchers at the University of Zurich have demonstrated in mice. The […]

AMA, AHA support refresher training for measuring blood pressure

(HealthDay)—Health care professionals (HCPs) should receive consistent and frequent training in measuring blood pressure (BP), according to a report prepared for the American Medical Association and the American Heart Association and released Nov. 18. Telephone interviews were conducted among 32 U.S. HCPs who work at a primary care location providing blood pressure measurement services to patients. Based on emerging themes, […]

Study identifies role of specific gene in hardening of blood vessel walls

Arterial wall calcification is the buildup of calcium in the blood vessel walls, which can often be a predictor of serious cardiovascular events like heart attacks and strokes. Scientists have long pointed to family history as one possible cause for this hardening of the arteries, but a new study published in Nature Genetics implicates a specific gene—HDAC9—in the calcification of […]
