After nearly 13 years of study and intense debate, a pair of new papers from the Perelman School of Medicine, at the University of Pennsylvania have confirmed exactly how a once-popular class of anti-inflammatory drugs leads to cardiovascular risk for people taking it.
⎯ A few months after the federal Government Accountability Office (GAO) issued a report on the use of psychoactive drugs by children in foster care in five states, a national study from PolicyLab at The Children’s Hospital of Philadelphia describes prescription patterns over time in 48 states. The updated findings show the percentage of children in foster care taking antipsychotics--a class of psychoactive drugs associated with serious side effects for children-- continued to climb in the last decade. At the same time, a slight decline was seen in the use of other psychoactive medications, including the percentage of children receiving 3 or more classes of these medications at once (polypharmacy).
Study of anti-hypertensive drug moxonidine finds, in an animal model, that the drug can improve heart function and survival independent of its effect on blood pressure
Researchers in Canada, Scotland and Australia have discovered that salicylate, the active ingredient in aspirin, directly increases the activity of the protein AMPK (AMP-activated protein kinase), a key player in regulating cell growth and metabolism. Salicylate, which is derived from willow bark, and is the active ingredient in aspirin, is believed to be one of the oldest drugs in the world with first reports of its use dating back to an Egyptian papyrus in 1543 BC.

• Drug combination superior to cancer drug alone.
• Data emphasize importance of understanding genetic mutations.
• Combination could be effective treatment for BRAF-mutant melanoma.
A Penn- and MIT-led team explained how rapamycin, a drug that extends mouse lifespan, also causes insulin resistance. The researchers showed in an animal model that they could, in principle, separate the effects, which depend on inhibiting two protein complexes, mTORC1 and mTORC2, respectively. The study suggests that molecules that specifically inhibit mTORC1 may combat age-related diseases without the insulin-resistance side effect, which can predispose people to diabetes.

A new topical gel now available by prescription significantly decreases the amount of time needed to treat actinic keratosis, a skin condition that is a common precursor to skin cancer, according to a multi-center trial led by researchers at Mount Sinai School of Medicine. The gel, called ingenol mebutate, is applied to the skin for just a few days, making it quicker and even more effective as current therapies require weeks to months to apply. The Phase III study results of the trial are published in the March 15, 2012 issue of the The New England Journal of Medicine.

Leading representatives of the American Epilepsy Society, American Academy of Neurology, and the Epilepsy Foundation today reported they have grave concerns about the implications and potential misuse of the anticonvulsant (AED) drug comparisons study recently released by the U.S. Agency for Health Research and Quality (AHRQ). The study’s intent is to provide an evidence-based analysis of the Effectiveness and Safety of Antiepileptic Medications in Patients With Epilepsy. But the AHRQ report has little clinical value according to the specialists in neurology and epilepsy and could negatively impact patient care.

Antibiotics that doctors typically prescribe for sinus infections do not reduce symptoms any better than an inactive placebo, according to investigators at Washington University School of Medicine in St. Louis.
Novel gene abnormalities discovered in a subpopulation of lung and colorectal tumors could potentially identify patients with a good chance of responding to highly specific “targeted” drugs already in use for treating other cancers, scientists report.
The genetic alterations – pieces of two genes fused together - showed up in a massive search of the DNA in stored tumor samples of non-small cell lung cancer and colorectal cancer, said researchers from Dana-Farber Cancer Institute and Foundation Medicine, Inc. These specific genetic abnormalities had not been previously linked to the two cancer types.
