In a study to be presented on February 15 between 8 a.m., and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in San Francisco, researchers will report findings that women with obstructive sleep apnea (OSA) and cardiac symptoms have a 31 percent incidence of cardiac dysfunction. The use of echocardiograms should be considered in the clinical management of these women.

In a study to be presented on February 15 between 1:15 p.m., and 3:30 p.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in San Francisco, researchers will report findings that suggest that consistent physical activity and healthier lifestyle changes beginning in a woman's first trimester can prevent excessive weight gain in obese pregnant women (with a Body Mass Index greater than 30), helping to avoid preterm delivery, hypertension and gestational diabetes.

In a study to be presented on February 16 between 8 a.m., and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in San Francisco, researchers will report findings that suggest shifting from a traditional model of obstetrical care to a laborist model improves pregnancy outcomes.

In a study to be presented on February 16 between 8 a.m., and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in San Francisco, researchers will report findings that suggest around-the-clock labor and delivery coverage decreased the odds of cesarean delivery.

In a study to be presented on February 16 between 8 a.m., and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in San Francisco, researchers will report findings that suggest comprehensive maternal hemorrhage protocols reduce utilization of blood products and improve patient safety.

In a study to be presented on February 14 between 8 a.m. and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's 33rd annual meeting, The Pregnancy Meeting ™, researchers will report findings that suggest that 17P, a form of progesterone, is not effective in preventing preterm birth among women with twin pregnancies — and may possibly be harmful.

A new study suggests that exercise may reduce Caucasian men's risk of developing prostate cancer. And among Caucasian men who do have prostate cancer, exercise may reduce their risk of having more serious forms of the disease. Unfortunately, the benefits do not seem to apply to African- American men. The study is published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

A lack of the protein endoglin in the blood vessels of tumour-bearing mice enables the spread of daughter tumours, according to researchers at Karolinska Institutet and Lund University in Sweden in a study published in the scientific periodical The Journal of Experimental Medicine. Given that the tumour vasculature constitutes an important barrier to the spread of cancer cells, the team suggests that drugs should be developed to strengthen the blood vessels' protective function.

Young adults, in a period of transition, are often reluctant to seek treatment for mental health problems because of the stigma, inadequate insurance coverage and difficulty finding a mental health care provider.

But a new preliminary study by researchers at Case Western Reserve University suggests that depression symptoms may be significantly reduced when 18- to 25-year-olds interact with computerized avatars—virtual 3D images of a healthcare provider like a nurse practitioner or physician —as a way to rehearse office visits ahead of time and learn self-management skills.

Researchers from North Carolina State University have found that one of the most aggressive invasive ant species in the United States – the Argentine ant – appears to have met its match in the Asian needle ant. Specifically, the researchers have found that the Asian needle ant is successfully displacing Argentine ants in an urban environment, indicating that the Asian needle ant – with its venomous sting – may be the next invasive species to see a population boom.

RESEARCH TRIANGLE PARK, N.C. – About two of every three children will experience at least one traumatic event before they turn 18. Despite this high rate of exposure, little is known about the effectiveness of treatments aimed at preventing and relieving traumatic stress symptoms that children may experience after such events, according to researchers at RTI International, the University of North Carolina School of Medicine, the RTI-UNC Evidence-based Practice Center, and Boston Medical Center.

Ultraviolet vision evolved at least eight times in birds from a common violet sensitive ancestor finds a study published in BioMed Central's open access journal BMC Evolutionary Biology. All of these are due to single nucleotide changes in the DNA.

ANN ARBOR — Researchers at the University of Michigan's Life Sciences Institute have found that amlexanox, an off-patent drug currently prescribed for the treatment of asthma and other uses, also reverses obesity, diabetes and fatty liver in mice.

The findings from the lab of Alan Saltiel, the Mary Sue Coleman director of the Life Sciences Institute, are scheduled to be published online Feb. 10 in the journal Nature Medicine.

An international team of scientists led by King's College London has discovered 24 new genes that cause refractive errors and myopia (short-sightedness).

Myopia is a major cause of blindness and visual impairment worldwide, and currently there is no cure. These findings, published today in the journal Nature Genetics, reveal genetic causes of the trait, which could lead to finding better treatments or ways of preventing the condition in the future.
