Quality of US diet improves, gap widens for quality between rich and poor

Quality of US diet improves, gap widens for quality between rich and poor

The quality of the U.S. diet showed some modest improvement in the last decade in large measure because of a reduction in the consumption of unhealthy trans fats, but the gap in overall diet quality widened between the rich and the poor Continue reading

Training your brain to prefer healthy foods

Training your brain to prefer healthy foods

It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods, according to new research by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and at Massachusetts General Hospital. Published online today in the journal Nutrition & Diabetes , a brain scan study in adult men and women suggests that it is possible to reverse the addictive power of unhealthy food while also increasing preference for healthy foods. “We don’t start out in life loving French fries and hating, for example, whole wheat pasta,” said senior and co-corresponding author Susan B Continue reading

Invisible blood in urine may indicate bladder cancer

Invisible blood in urine may indicate bladder cancer

New research which finds that invisible blood in urine may be an early warning sign of bladder cancer is likely to shape guidelines for clinicians. Scientists at the University of Exeter Medical School found that one in 60 people over the age of 60 who had invisible blood in their urine (identified by their GP testing their urine) transpired to have bladder cancer.

Sniffing-out smell of disease in feces: ‘Electronic nose’ for rapid detection of clostridum difficile infection

Sniffing-out smell of disease in feces: ‘Electronic nose’ for rapid detection of clostridum difficile infection

A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhea, temperature and stomach cramps, has been developed by a team at the University of Leicester. Using a mass spectrometer, the research team has demonstrated that it is possible to identify the unique ‘smell’ of C-diff which would lead to rapid diagnosis of the condition. What is more, the Leicester team say it could be possible to identify different strains of the disease simply from their smell — a chemical fingerprint — helping medics to target the particular condition.

New way to diagnose malaria by detecting parasite’s waste in infected blood cells

New way to diagnose malaria by detecting parasite’s waste in infected blood cells

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye, and looks under a microscope for the Plasmodium parasite, which causes the disease.

Batteryless cardiac pacemaker is based on automatic wristwatch

A new batteryless cardiac pacemaker based on an automatic wristwatch and powered by heart motion was presented at ESC Congress 2014 today by Adrian Zurbuchen from Switzerland. The prototype device does not require battery replacement. Continue reading

Antidepressants show potential for postoperative pain

Antidepressants show potential for postoperative pain

After a systematic review of clinical trials based on administering antidepressants for acute and chronic postsurgical pain, researchers have concluded that more trials are needed to determine whether these drugs should be prescribed for postsurgical pain on a regular basis. Dr. Ian Gilron, a professor and director of clinical pain research in the Department of Anesthesiology, and his team of seven researchers reviewed 15 trials to determine whether the use of antidepressants for pain relief post-surgery would work more effectively than painkillers such as opioids, local anesthetics, or acetaminophen.

Preventing cancer from forming ‘tentacles’ stops dangerous spread

Preventing cancer from forming ‘tentacles’ stops dangerous spread

A new study from the research group of Dr. John Lewis at the University of Alberta (Edmonton, AB) and the Lawson Health Research Institute (London, ON) has confirmed that “invadopodia” play a key role in the spread of cancer. The study, published in Cell Reports , shows preventing these tentacle-like structures from forming can stop the spread of cancer entirely Continue reading

Evidence mounting that older adults who volunteer are happier, healthier

Evidence mounting that older adults who volunteer are happier, healthier

Older adults who stay active by volunteering are getting more out of it than just an altruistic feeling — they are receiving a health boost! A new study, led by the Rotman Research Institute at Baycrest Health Sciences and published online this week in Psychological Bulletin , is the first to take a broad-brush look at all the available peer-reviewed evidence regarding the psychosocial health benefits of formal volunteering for older adults.
