MONDAY, Jan 14, 2019 — The holidays, winter weather, and the flu season have all prompted a blood shortage, the American Red Cross warns. The organization said today it had about 27,000 fewer blood and platelet donations than needed during Christmas and New Year’s. People nationwide, especially those with type O blood, are urged to

THURSDAY, Dec. 20, 2018 — A miniaturized optical coherence tomography (OCT) imaging needle can detect blood vessels intraoperatively in the human brain in vivo, according to a study published online Dec. 19 in Science Advances. Hari Ramakonar, M.B.B.S., from Sir Charles Gairdner Hospital in Nedlands, Australia, and colleagues developed an imaging needle that is able

A new study links higher levels of several key nutrients in the blood with more efficient brain connectivity and performance on cognitive tests in older adults. The study, reported in the journal NeuroImage, looked at 32 key nutrients in the Mediterranean diet, which previous research has shown is associated with better brain function in aging.

Credit: CC0 Public Domain University of Minnesota Medical School researchers decided to delve into an area where little data currently exists. They wanted to know what happens after these patients with abnormal blood glucose measurements are discharged? Are uncontrolled blood glucose levels associated with worse outcomes after patients are discharged from the hospital? Surprisingly, despite

Tim Landis was a healthy 66-year-old who hiked, biked and jogged, wasn’t overweight and watched what he ate. But after he died suddenly of a heart attack in January, tests revealed years of untreated high blood pressure that caused cardiovascular disease. At his annual physicals, Tim’s systolic blood pressure (the top number) was usually in

Smoking, diabetes and high blood pressure increase the risk of a heart attack more in women than in men, new research from The George Institute for Global Health at the University of Oxford has found. The study, of 472,000 participants aged 40-69, found that smoking, diabetes, high blood pressure and having a BMI >25 puts

High blood pressure can do critical damage to your heart. But it affects other parts of the body, too, including the eyes. Believe it or not, when you don’t take care of your heart, you may be causing harm elsewhere, too. Here’s how blood pressure can affect your eyes. High blood pressure can cause eye

More and more people are giving up smoking, and they are sensible to do so. Cigarette smoking is “the leading preventable cause of death in the United States,” according to the Centers for Disease Control and Prevention (CDC), with cigarettes causing over 480,000 yearly deaths. However, as the use of regular cigarettes is declining, more

If you’re struggling to lower your blood pressure, it likely has to do with two things: Diet and exercise. It’s important to get daily exercise. Go for a walk every day to get your blood pumping and improve your heart health. The foods you eat also have a major impact on heart health. If you’re

An enzyme activated in diabetics has been found to cause previously aligned cells in a blood vessel to reverse their orientation, creating misalignments that allow veins and arteries to leak three times more blood proteins than normally constructed blood vessels. Controlling the enzyme could ease symptoms of swelling, nerve pain, localized low blood pressure, and

People with high blood pressure taking medication for their condition are more likely to benefit from the therapy if they have good oral health, according to new research in the American Heart Association’s journal Hypertension. Findings of the analysis, based on a review of medical and dental exam records of more than 3,600 people with

Smoking cannabis may boost your risk of stroke by cutting off blood supply to the brain, scientists say Stroke increased by 15% among marijuana users between 2010 and 2014 Rates of stroke in non-cannabis users stayed constant over that time Marijuana use may be on the rise as it becomes legalised around the world Compounds

A Duke University research team has found a way to help sporting officials detect whether an athlete’s blood has been doped by an infusion of their own stored blood. While tests have been developed to detect two of the three most common methods of dramatically boosting the oxygen-carrying capacity of a competitor’s blood, so-called “autologous”

Simple blood and saliva tests that cost just £40 could help prevent heart attacks, scientists say Major study proves that scientists can identify people at risk of a heart attack  Scientists found DNA testing can be used to spot those with increased risk Currently more than 190,000 people suffer a heart attack in the UK each year

For about one in five people with what appears to be hard-to-treat, or resistant, high blood pressure, they simply aren’t taking prescribed medications, new research suggests. Drug-resistant hypertension appears to be on the rise and occurs when blood pressure remains above normal even after the patient has been put on three or more blood pressure

High blood pressure rates could nearly double in women of childbearing age if the latest guidelines are used, according to a new study. But researchers say more investigation is needed to see if those lower blood pressure targets in pregnant women are safe—or effective. The study, published Sept. 10 in the journal Hypertension, set out

The first simple blood test to identify your body’s precise internal time clock as compared to the external time has been developed by Northwestern Medicine scientists. The test, TimeSignature—which requires only two blood draws—can tell physicians and researchers the time in your body despite the time in the external world. For instance, even if it’s

Kids with food insecurity, meaning they lack good access to nutritional foods, were more likely to have high blood pressure than kids with secure access to food, according to a study presented at the American Heart Association’s Joint Hypertension 2018 Scientific Sessions. “High blood pressure—even in childhood—matters,” said study author Andrew Michael South, M.D., assistant

One way to control blood sugar is to eat a healthful diet. Generally, foods and drinks that the body absorbs slowly are best because they do not cause spikes and dips in blood sugar. The glycemic index (GI) measures the effects of specific foods on blood sugar levels. People looking to control their levels should

Our researchers have revealed the identities of new subsets of immune cells at the frontline of our body’s defenses against infection. The research team’s discovery expands the understanding of immune cells called granulocytes – immune cells that can trigger inflammation and engulf microbes to slow an infection’s progress. As well as protecting against infection, granulocytes
