Bipolar and pregnant

Posted: 01 Nov 2013 02:24 PM PDT

New research offers one of the first in-depth views of how metabolism changes during pregnancy reduce the effect of a commonly used drug to treat bipolar disorder. The blood level of the drug decreased during pregnancy, resulting in worsening symptoms. The new findings can help physicians prevent bipolar manic and depressive episodes in their pregnant patients, which are risky for the health of the mother and her unborn child.

A galaxy within us: Our gut microbiota and how it can be programmed by food

Posted: 01 Nov 2013 09:54 AM PDT

Who would have thought that the human body contains over 10 times the amount of bacterial cells as human cells? These bacteria - now collectively called the gut microbiota - number in their trillions and are made up of more than a 1,000 different species most of which are beneficial in some way.

US preterm birth rate drops to 15-year low

Posted: 01 Nov 2013 06:19 AM PDT

The United States' preterm birth rate dropped for the sixth year in 2012 to 11.5 percent, a 15-year low. The nation again earned a "C" on the Report Card. Alaska, California, Maine, New Hampshire, Oregon and Vermont earned an "A." The March of Dimes estimated that, since 2006, about 176,000 fewer babies have been born too soon because of improvement in the preterm birth rate, potentially saving about $9 billion in health and societal costs.

Patients with heart failure need specialist care

Posted: 01 Nov 2013 06:17 AM PDT

New research shows that patients with heart failure have high mortality and often are undertreated. According to a study, many more of these patients would benefit from advanced treatment by heart specialists – something that could be decided by a simple evaluation of five common risk factors for early death due to heart failure.

'Flipping the switch' reveals new compounds with antibiotic potential

Posted: 31 Oct 2013 02:55 PM PDT

Researchers have discovered that one gene in a common fungus acts as a master regulator, and deleting it has opened access to a wealth of new compounds that have never before been studied -- with the potential to identify new antibiotics.

New way to monitor induced comas

Posted: 31 Oct 2013 02:55 PM PDT

After suffering a traumatic brain injury, patients are often placed in a coma to give the brain time to heal and allow dangerous swelling to dissipate. These comas, which are induced with anesthesia drugs, can last for days. During that time, nurses must closely monitor patients to make sure their brains are at the right level of sedation -- a process that scientists now describe as "totally inefficient." An automated system could offer better control of patients' brain states.
