American physicians prescribe placebos on occasion

American physicians’ use of placebos in clinical practice in the 21st Century, 45 percent of Chicago internists report they have used a placebo at some time during their clinical practice. – In the first study examining American physicians’ use of placebos in clinical practice in the 21st Century, 45 percent of Chicago internists report they have used a placebo at some time during their clinical practice researchers report in the January issue of Journal of General Internal Medicine.

Lung cancer cells’ survival gene 14-3-3zeta seen as drug target

Lung cancer cells’ survival gene 14-3-3zeta seen as drug target, as lung cancer cells can?t survive on their own when this key gene called 14-3-3zeta is silenced. – One of the deadliest forms of cancer appears to carry a specific weakness. When a key gene called 14-3-3zeta is silenced, lung cancer cells can’t survive on their own, researchers have found.

Obese pregnant women give birth to heavier babies

New study suggests that maternal body composition at or near conception has important implications for offspring?s obesity, and obesity during conception phase may set the stage for offspring?s obesity risk. – The number of overweight and obese Americans continues to grow rapidly. Today, 50 percent of adults are overweight and up to 20 percent are obese. While the number of overweight/obese children is at an all time high, the steady increase of overweight infants ? individuals under 11 months old ? is alarming.

MRI for better assessment of liver fibrosis

Chronic liver disease and cirrhosis remains a major public health problem worldwide. While the majority of complications from chronic liver disease result from progressive hepatic fibrosis, the available diagnostic tests used in clinical practice are not sensitive or specific enough to detect occult liver injury at early or intermediate stages. – MRI imagery is emerging as a non-invasive way to determine the existence and extent of hepatic fibrosis. It could eventually help the development of pharmacologic strategies to combat the condition.

Mouth rinse gargle test for cancer

A simple mouth rinse may provide a new way to screen for head and neck cancers in people at high risk for these diseases. – A morning gargle could someday be more than a breath freshener ? it could spot head and neck cancer, say scientists at the Johns Hopkins Kimmel Cancer Center. Their new study of a mouth rinse that captures genetic signatures common to the disease holds promise for screening those at high risk, including heavy smokers and alcohol drinkers.

Some brain injuries reduce the likelihood of post-traumatic stress disorder

Vets with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder (PTSD). – A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder (PTSD).

7 tips to keep the holidays happy

Take seven steps for happy holidays as mentioned by Dennis Orthner to prevent tension at family gatherings. – Today’s busy families have moved toward a pattern of individual activities (listening to an iPod, surfing the internet), rather than joint activities, according to Dennis Orthner, a professor at the University of North Carolina at Chapel Hill School of Social Work.

Late developmental growth may risk depression

Children with low weight during infancy or slight developmental delays may be at greater risk for developing depression.
– Psychiatrists remain divided as to how to define and classify the mood and anxiety disorders, the most common mental disorders. Committees across the globe are currently pondering how best to carve nature at its anxious joints for the fifth version of the Diagnostic and Statistical Manual (DSM-V), the “gold standard” reference book for psychiatrists.

Kids eat more fruits, vegetables

One of the major contributing factors to the high rate of overweight children in the United States is that they do not consume the daily recommended servings of fruits and vegetables.
– A new UCLA study has found that elementary schools can significantly increase the frequency of fruit and vegetable consumption among low-income students by providing a lunch salad bar.

Living embryonic heart cells prevent cardiac arrhythmias

Researchers implant embryonic cells into damaged hearts and prevent life-threatening heart arrhythmias.
– When researchers at Cornell, the University of Bonn and the University of Pittsburgh transplanted living embryonic heart cells into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.

Aging brain failures to communicate

Cognitive decline in aging may be linked to disruption of communication between different regions of the brain.
– A team of Howard Hughes Medical Institute researchers has shown that normal aging disrupts communication between different regions of the brain. The new research, which used advanced medical imaging techniques to look at the brain function of 93 healthy individuals from 18 to 93 years old, shows that this decline happens even in the absence of serious pathologies like Alzheimer’s disease.

Gene identified that influences alcohol consumption

Researchers applied a variety of genetic and analytic techniques to identify a chromosomal region, and ultimately a gene, associated with alcohol preference.
– A variant of a gene involved in communication among brain cells has a direct influence on alcohol consumption in mice, according to a new study by scientists supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), and the U.S. Army.
