Blood Pressure Spike Around Doctors Might Point to Heart Problem

Some older people who get what’s known as white coat hypertension – a spike in blood pressure at the doctors’ office – may have an increased risk of heart disease and stroke, a study suggests. White coat hypertension is pretty common – lots of people get stressed out around doctors and it’s not unusual for this to result in high blood pressure readings for patients who have normal blood pressure outside the exam room, researchers note in the Journal of the American College of Cardiology. When researchers examined data on…

Researchers have identified a blood test that may help predict how severely a newborn can be affected by alcohol exposure during pregnancy. Foetal alcohol spectrum disorders (FASD) is a severe form of mental and physical disabilities. Children and adults affected by FASD may experience a range of symptoms, from physical changes like a small head and subtle differences in facial characteristics to learning difficulties and behavioural issues. The study showed that moderate to high levels of alcohol exposure during early pregnancy resulted in significant differences in some circulating small RNA…

Eating Cheese May Lower High Blood Pressure

Consuming sodium in the form of a dairy product, such as cheese, may protect against some of sodium’s effects on the cardiovascular system, such as high blood pressure, researchers say. According to researchers, the protection comes from antioxidant properties of dairy proteins in cheese. The results suggest that when sodium is consumed in cheese it does not have the negative vascular effects that researchers observed with sodium from non-dairy sources. “We found that when participants ate a lot of sodium in cheese, they had better blood vessel function — more…

Prostate cancer spread can be predicted through tumour cells in blood samples

Prostate cancer spread can be predicted through tumour cells in blood samples (Shutterstock Images) A new study says that researchers have found a group of circulating tumour cells in prostate cancer patient blood samples which are linked to the spread of the disease. This is the first time these cell types have been shown to be a promising marker for prostate cancer spread. In a study, presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool, of around 80 samples from men with prostate cancer, scientists at the…

Lab-Grown Blood Vessels To Help Kids With Heart Defects

In a groundbreaking feat, a team of biomedical engineers has successfully implanted lab-grown artificial blood vessels in young lambs which are capable of growth within the recipient. If confirmed in humans, these new vessel grafts would prevent the need for repeated surgeries in some children with congenital heart defects, said the team from the University of Minnesota. “This might be the first time we have an ‘off-the-shelf’ material that doctors can implant in a patient and it can grow in the body,” said professor Robert Tranquillo from the University of…

Carotid is key to high blood pressure

Carotid is key to high blood pressure (Thinkstock photos/Getty Images) Removing one carotid body from some patients with high blood pressure can provide immediate and sustained fall in blood pressure, finds a new study. Carotid bodies, a small cluster of chemoreceptors and supporting cells located near the fork (bifurcation) of the carotid artery that feed the brain with blood, appear to be a cause of high blood pressure. “The falls in blood pressure are impressive — more than pharmacological medication — and demonstrate the potential for targeting the carotid body…
