Progestogens May Prevent Premature Births
Date: Sep-11-2012Progestogens may be given to pregnant women whose children were previously born premature, in order to avoid a subsequent early birth, according to a Vanderbilt study in Obstetrics & Gynecology. Researchers found that when these women are given progestogens while expecting a single child, they receive benefits from the additional hormone. Progestogens are natural or synthetic forms of progesterone, a female hormone that naturally increases while a woman is pregnant...
Insomnia Medicine Suvorexant, New Phase III Data Announced
Date: Sep-11-2012Merck remains on target to submit a New Drug Application to the FDA in 2012Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced new data for suvorexant, the investigational medicine Merck is developing for the treatment of insomnia. The new data are from one of the longest, continuously-dosed, placebo-controlled trials of a sleep medication ever conducted. This 12-month study was designed to assess the safety of suvorexant, while also evaluating its longer term efficacy...
Tension On Gut Muscles Induces Cell Invasion In Zebrafish Intestine, Mimicking Cancer Metastasis, Penn Study Finds
Date: Sep-11-2012The stiffness of breast tissue is increasingly recognized as an important factor explaining the onset of breast cancer. Stiffening induces molecular changes that promote cancerous behavior in cells. Bioengineering studies have found that breast cancer cells grown on a 3-D gel have enhanced cell replication and decreased organization as rigidity increases. These signals are probably coordinated by surface proteins that communicate with connective tissue, to regulate cell replication, death, and movement...
Subsidies Change Incentives For Adoption Of Foster Children: Study
Date: Sep-11-2012The structure of a federal program that provides monthly subsidies to promote the adoptions of special needs children in foster care may actually be delaying some adoptions, according to a new study by University of Notre Dame economist Kasey Buckles. The Adoption Assistance and Child Welfare Act (AACWA), passed in 1980, provides an average of $670 per month for foster parents of special needs children, while adoptive parents of special needs children receive an average of $571 per month...
UCSC Study Shows How Urchin-Loving Otters Can Help Fight Global Warming
Date: Sep-11-2012Can an abundance of sea otters help reverse a principal cause of global warming? A new study by two UC Santa Cruz researchers suggest that a thriving sea otter population that keeps sea urchins in check will in turn allow kelp forests to prosper. The spreading kelp can absorb as much as 12 times the amount of CO2 from the atmosphere than if it were subject to ravenous sea urchins, the study finds...
The Nose Knows: Gene Therapy Restores Sense Of Smell In Mice
Date: Sep-11-2012A team of scientists from Johns Hopkins and other institutions report that restoring tiny, hair-like structures to defective cells in the olfactory system of mice is enough to restore a lost sense of smell. The results of the experiments were published online this week in Nature Medicine, and are believed to represent the first successful application of gene therapy to restore this function in live mammals. An expert in olfaction, Randall Reed, Ph.D...
Hypertension Study Compares Two Treatment Methods
Date: Sep-11-2012Trial results demonstrated greater clinic systolic blood pressure reductions with the chlorthalidone combination Results of a 10-week, phase 3 study published online in the American Journal of Medicine found the clinic systolic blood pressure (SBP) reductions of a fixed-dose combination of azilsartan medoxomil and chlorthalidone were significantly greater at six and ten weeks than those of azilsartan medoxomil co-administered with hydrochlorothiazide...
Health-Care Costs At End Of Life Exceed Total Assets For 25 Percent Of Medicare Population
Date: Sep-11-2012As many as a quarter of Medicare recipients spend more than the total value of their assets on out-of-pocket health care expenses during the last five years of their lives, according to researchers at Mount Sinai School of Medicine. They found that 43 percent of Medicare recipients spend more than their total assets minus the value of their primary residences. The findings appear online in the current issue of the Journal of General Internal Medicine. The amount of spending varied with the patient's illness...
Precautions For Tick-Borne Disease Extend "Beyond Lyme"
Date: Sep-11-2012This year's mild winter and early spring were a bonanza for tick populations in the eastern United States. Reports of tick-borne disease rose fast. While Lyme disease is the most common tick-borne disease in the Northeast and Upper Midwest, new research results emphasize that it is not the greatest cause for concern in most Southeastern states. The findings were published recently in a paper in the journal Zoonoses and Public Health...
Is Alzheimer's Preventable Before Damage Is Done?
Date: Sep-11-2012What if there were a way to catch Alzheimer's disease before it occurred? Is there a method to stopping this terminal and most common form of dementia? Researchers decided to see whether there might be a telling sign of Alzheimer's development which is detectable before any permanent damage has already occured. Modern medicine has not yet advanced to the point of completely reversing the damage caused by Alzheimer's, although certain treatments do slow the progression of the disease...
