CT angiography improves detection of heart disease in African-Americans

Researchers may have discovered one reason that African-Americans are at increased risk for heart attacks and other cardiovascular events. According to a new study, African Americans have increased levels of non-calcified plaque, which consists of buildups of soft deposits deep in the walls of the arteries that are not detected by some cardiac...

Clinicians should aim for comprehensive lipid control using lifestyle as a first step and tailoring treatment to patients: New guidelines

Cardiovascular disease (CVD), driven by the global pandemics of obesity and diabetes, poses a daunting challenge to clinicians in the 21st century. Despite progress, there is still much to be done to improve the control of dyslipidaemia, a key risk factor. In Europe, as many as one-half of patients are inadequately treated. The first European guidelines specifically focused on managing...

New measurement important complement to GI

Many people are careful to follow a low glycaemic index (GI) diet. However, the glycaemic index concept has some shortcomings, in the view of one young researcher, who has developed a complementary method, ‘glycaemic profile’ or GP.

A lack of structure facilitates protein synthesis

Texts without spaces are not very legible, as they make it very difficult for the reader to identify where a word begins and where it ends. When genetic information in our cells is read and translated into proteins, the enzymes responsible for this task face a similar challenge. They must find the correct starting point for protein synthesis. Therefore, in organisms with no real nucleus, a point...

Lack of empathy following traumatic brain injury associated with reduced responsiveness to anger

Egocentric, self-centred, and insensitive to the needs of others: these social problems often arise in people with severe traumatic brain injury (TBI) and have been attributed in part to a loss of emotional empathy, the capacity to recognise and understand the emotions of other people. A new study has recently revealed evidence of a relationship between physiological responses to anger and a...

First joint ESC/EAS guidelines for the management of dyslipidaemias

Cardiovascular disease (CVD), driven by the global pandemics of obesity and diabetes, poses a daunting challenge to clinicians in the 21st century. Despite progress, there is still much to be done to improve the control of dyslipidaemia, a key risk factor. In Europe, as many as one-half of patients are inadequately treated.1,2 The first European guidelines specifically focused on managing...

Mood and experience: Life comes at you

(Medical Xpress) -- Living through weddings or divorces, job losses and children’s triumphs, we sometimes feel better and sometimes feel worse. But, psychologists observe, we tend to drift back to a “set point”—a stable resting point, or baseline, in the mind’s level of contentment or unease.
