'Tickling' your ear could be good for your heart
Stimulating nerves in your ear could improve the health of your heart, researchers have discovered. Scientists used a standard TENS machine like those designed to relieve labour pains to apply electrical pulses to the tragus, the small raised flap at the front of the ear immediately in front of the ear canal.

Engineering bone growth: Coated tissue scaffolds help body grow new bone to repair injuries or congenital defects
Chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue. This type of coated scaffold could offer a dramatic improvement over the current standard for treating bone injuries, which involves transplanting bone from another part of the patient's body -- a painful process that does not always supply enough bone.

Ruxolitinib for myelofibrosis: Indication of considerable added benefit
In comparison with 'best supportive care', there is an indication that the new drug is better at relieving symptoms, and a hint of longer survival. Myelofibrosis is a rare disease of the bone marrow, in which the bone marrow is replaced by connective tissue. As a consequence of this so-called fibrosis, the bone marrow is no longer able to produce enough blood cells. Sometimes the spleen or the liver takes over some of the blood production. Then these organs enlarge and can cause abdominal discomfort and pain.

Fruit, vegetable intake still too low; human nutritionist says to focus on lunch
Children between the ages of 2 and 18 are eating more whole fruits and drinking less fruit juice, a new report finds after the implementation of a new program. However, vegetable intake remains the same, they say. One expert says the switch from fruit juice to whole fruit has been a big improvement.

Genetic key to lupus shows potential of personalized medicine
DNA sequencing of a lupus patient has identified a specific genetic mutation that is causing the disease, opening the way for personalized treatments. Researchers identified a variant in the TREX1 gene. This mutation caused the patient's cells to produce a molecule called interferon-alpha. Clinical trials are already underway for drugs to target interferon-alpha in adults.

Women will benefit from the Affordable Care Act's contraceptive coverage
Women could benefit greatly from the Affordable Care Act's mandate for contraceptive coverage, according to researchers. The Affordable Care Act requires private insurance plans -- except those grandfathered or exempted due to employers' religious beliefs -- to provide women with access to all FDA-approved contraceptive methods without cost-sharing. This first-dollar coverage "has the potential to dramatically shift contraceptive use patterns, to reduce the U.S. unintended pregnancy rate ... and to improve the health of women and families," write experts.

Intimacy a strong motivator for PrEP HIV prevention
Many HIV-negative gay or bisexual men in steady relationships with other HIV-negative men don't always use condoms out of a desire for intimacy. That same desire, according to a new study, makes such men more inclined to use antiretroviral medications to prevent getting HIV, a recommended practice known as PrEP.

Taking a stand: Balancing the benefits, risks of physical activity in children
Today the Canadian Society of Exercise Physiology took a stand on the promotion of childhood physical activity. This position stand provides an important overview of knowledge in the area of risk of physical activity for children and suggests both practical guidelines and a research agenda. Uniquely, this position stand addresses both benefits and risks of physical activity for children.

The difficult question of Clostridium difficile
Clostridium difficile is a major problem as an aetiological agent for antibiotic-associated diarrhea. The mechanism by which the bacterium colonizes the gut during infection is poorly understood, but undoubtedly involves a myriad of components present on the bacterial surface. This study provides some insights that may help in developing a new type of drug to treat the infection.
