Ovarian cancer finding may be a 'win-win' for at-risk women who wish to have a family

2011-04-08
(Press-News.org) PORTLAND, Ore. – Researchers at Oregon Health & Science University's Oregon National Primate Research Center may have good news for women at high-risk for ovarian cancer who also want to have children. The research suggests that a layer of cells, which serve as the "breeding ground" for ovarian cancer, may be removed yet allow the women to have children. This would be a vast improvement over the current prevention strategy for women at high risk for ovarian cancer: Removal of the ovaries entirely. The research is published in the current online edition of the journal Human Reproduction. It will also appear in a future printed edition of the journal. The new treatment approach being tested at OHSU focuses on a layer of cells that surround the ovaries called ovarian surface epithelium. These cells, which have no known function, are where ovarian cancer takes root. To conduct the research, scientists washed away the ovarian surface epithelium in healthy female monkeys through minimally invasive surgery. Following the procedure, the animals were closely observed to determine if removal of the cells changed function of the ovaries themselves. This observation revealed that the animals' ovaries produced eggs at a normal rate, as well as estrogen and progesterone in normal cyclic patterns. The procedure did not appear to affect the health of the ovaries or the overall health of the animals. Because women with a family history of the disease are at a much higher risk for ovarian cancer themselves, many of these women choose to have their ovaries removed as a precaution. Of course for young women, this can be a major quality of life issue as the treatment prevents future childbirth and removes the primary source of a woman's estrogen. "While additional studies are necessary, this procedure suggests that we may have found a much less invasive strategy for preventing ovarian cancer in high-risk women while at the same time maintaining fertility," said Jay Wright, Ph.D., a scientist in the Division of Reproductive Sciences at the Oregon National Primate Research Center. "This is a key finding in monkeys because their reproductive system is so similar to the human female reproductive system."

### The National Institute of Child Health and Human Development and the National Center for Research Resources which are components of the National Institutes of Health, and the OHSU Foundation funded this research.

About Ovarian Cancer Source: Centers for Disease Control and Prevention Each year, approximately 20,000 women in the United States are diagnosed with ovarian cancer. Among women in the United States, ovarian cancer is the eighth most common cancer and the fifth leading cause of cancer death. In 2010, there were 21,880 new cases ovarian cancer diagnosed in the United States and 13,850 deaths.

Treatment for depression a long-term solution

2011-04-08
(Edmonton) Ian Colman, an epidemiologist in the School of Public Health at the University of Alberta, recently completed a study that suggests that treatment of depression may have long-term benefits. The data Colman reviewed came from the National Population Health Survey, a longitudinal Canadian study, and showed depressed adults who use antidepressants are three times less likely to be depressed eight years later, compared to depressed adults who don't use antidepressants. To date, research into the effects of antidepressant treatments for individuals with major ...

Traumatic Brain Injury: Deceleration Injury and Other Causes

2011-04-08
According to the Centers for Disease Control and Prevention, across the nation at least 1.7 million people suffer a traumatic brain injury (TBI) every year. Of those injured, 52,000 die. There are more then 5.3 million people living in the United States with disabilities caused by TBI. These figures may underreport instances of TBI, since those the number of people who receive no hospital or emergency room care is currently unknown. Traumatic Brain Injury Symptoms TBI occurs when trauma causes damage to the brain, frequently a result of a sudden and violent blow to ...

Warning labels better than a fat tax, University of Alberta study shows

2011-04-08
Warning labels on junk food would be more effective than a "fat" tax for deterring overweight people from making unhealthy purchases, a new University of Alberta study has found. A survey of 364 shoppers in random Alberta grocery stores showed that while price alone wouldn't deter people from reaching for junk food, shoppers—including those with the heaviest body mass index—did heed a label that warned of high fat content and included a note that the item was being taxed because of it. The study asked shoppers to choose between high-fat and healthier snacks in the ...

Breakthrough study confirms cause of short gamma-ray bursts

Breakthrough study confirms cause of short gamma-ray bursts
2011-04-08
WASHINGTON -- A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs). The study provides the most detailed glimpse of the forces driving some of the universe's most energetic explosions. The state-of-the-art simulation ran for nearly seven weeks on the Damiana computer cluster at the Albert Einstein Institute (AEI) in Potsdam, Germany. It traces events that unfold over 35 milliseconds -- about three times faster than ...

Study Shows No Reduction in Medical Errors Since 1999

2011-04-08
In 1999, the Institute of Medicine released a report indicating that medical mistakes accounted for more than one million injuries and as many as 98,000 deaths every year in the United States. The report spawned a national movement to reduce medical errors, but a new study published by The New England Journal of Medicine shows bleak results. The first large study in a decade to analyze and track harm resulting from medical care shows that the number of patients suffering harm from medical errors or inadvertent problems persists at a steady pace. Remedial Efforts Falling ...

Property Owners May Be Found Negligent For Inadequate Security

2011-04-08
If someone entered your apartment -- because the front door locks were broken -- and physically assaulted you, it may be possible to hold the landlord legally responsible. The same is true for management in a restaurant or other public place, if an attack occurs there. Under traditional laws of negligence, one private person has no duty to another private person to protect him or her from an assault or other violent act. For many years, landlords, innkeepers, and other property owners used this quirk of the common law to avoid liability. But across the country, courts ...

A recent report released by Florida's Office of the State Court's Administrator (OSCA) showing a marked decrease in its backlog of court foreclosure cases does not mean that the crisis is easing. South Florida experienced a drop of 8.9 percent in its foreclosure case load in the final three months of 2010, while Miami-Dade and Broward Counties saw a drop of 44.2 percent from the last quarter in the disposition of foreclosure cases. None, ...

Ancient corals provide insight on the future of Caribbean reefs

Ancient corals provide insight on the future of Caribbean reefs
2011-04-08
CORAL GABLES (April 7, 2011) -- Climate change is already widely recognized to be negatively affecting coral reef ecosystems around the world, yet the long-term effects are difficult to predict. University of Miami (UM) scientists are using the geologic record of Caribbean corals to understand how reef ecosystems might respond to climate change expected for this century. The findings are published in the current issue of the journal Geology. The Pliocene epoch--more than 2.5 million years ago--can provide some insight into what coral reefs in the future may look like. ...

Unprepared cities vulnerable to climate change

2011-04-08
BOULDER—Cities worldwide are failing to take necessary steps to protect residents from the likely impacts of climate change, even though billions of urban dwellers are vulnerable to heat waves, sea level rise, and other changes associated with warming temperatures. A new examination of urban policies by Patricia Romero Lankao at the National Center for Atmospheric Research (NCAR), in conjunction with an international research project on cities and climate change, warns that many of the world's fast-growing urban areas, especially in developing countries, will likely suffer ...
