Flashbacks are vivid, recurring, intrusive, and unwanted mental images of a past traumatic experience. They are a sine qua non of post-traumatic stress disorder (PTSD). Although drugs and cognitive behavioral interventions are available to treat PTSD, clinicians would prefer to utilize some sort of early intervention to prevent flashbacks from developing in the first place.
Well, researchers at Oxford University appear to have found one. Remarkably, all it takes is playing Tetris. Yes, Tetris!
The team responsible for the discovery was led by Emily Holmes. The writeup appears in the November issue of PLoS ONE. Holmes and colleagues had reasoned that the human brain has a limited capacity to process memories, and that memory consolidation following a traumatic experience is typically complete within six hours after the event. Holmes’ team also knew that playing Tetris involved the same kind of mental processing as that involved with flashback formation. So they figured if they had people play Tetris during that six-hour window after the traumatic event, it might interfere with memory consolidation of the traumatic experience. That, in turn, would reduce or eliminate the flashbacks. The idea worked like a charm. Read more »

It’s beginning to look like chocolate, especially dark chocolate, really and truly is a heart healthy snack, though only if it’s consumed in small quantities.
A delectable taste of this news came last spring, in the form of a study by German scientists which appeared in the European Heart Journal. It was a retrospective study of nearly 20,000 people, and it showed that folks in the highest quartile for chocolate consumption (meaning they consumed 7.5 grams of chocolate per day — the equivalent of 2 to 3 small squares of a Hershey bar), had lower blood pressure, a 27 percent lower risk of heart attack, and a 48 percent lower risk of stroke than those in the lowest quartile (about 1.7 grams per day).
Now, a new study in the journal Cardiovascular Pharmacology has lent credence to those findings by suggesting a mechanism through which chocolate reduces blood pressure. In the study, Ingrid Persson and colleagues at Linkoping University showed that dark chocolate inhibits the activity of the angiotensin-converting enzyme (ACE). This enzyme helps regulate fluids and salt metabolism in the body. It is the target of many well-known antihypertensive drugs including captopril, lisinopril and enalopril. Read more »

Scientists know that our perceptions about taste and texture drive our food preferences. They know quite a lot about the role of taste in this regard, and the results of some recent experiments have shed new light on the role of texture as well, particularly as it relates to foods containing starch.
Starch is a major component of potatoes, rice, corn, wheat and the enormous variety of foods derived from them. It is also added to many other products from maple syrup to pudding. In fact, starch accounts for 40 to 60 percent of the calorie content in the average Western diet, and more than that in many Asian and third-world diets.
Humans begin digesting starch in the mouth, where the salivary glands secrete an enzyme known as amylase. This enzyme breaks down starch and other complex carbohydrates into simpler sugar molecules which end up being absorbed from the small intestine into the bloodstream. Read more »

Flush from their big win in the midterms, the Boehners are vowing to repeal and replace the Big O’s health reform law. They pose a legitimate threat, but an even larger one lies in the courts, where suits challenging the constitutionality of the law have been popping up like fireflies on a late August night.
In Virginia for example, Republican-appointed Federal District Court Judge Henry Hudson has indicated that the Individual Mandate — a key provision of the law that has been challenged in a suit filed in his court by the state’s Republican Attorney General — might not pass his sniff test.
Hudson said he’d rule on the matter this month. If he deems the provision to be unconstitutional, he might (it’s unlikely, but he might) enjoin the law altogether until higher courts rule on the matter. Holy Kazakhstan, Batman!
An official at Camp Obama, who spoke with the New York Times under the condition that his name not be WikiLeaked, acknowledged that Hudson’s thumbs appear to be pointing downward, indeed. Read more »

Scientists have discovered a new, highly-transmissible gene that could, quite easily in fact, open a frightening new front in the ongoing global war against superbugs.
The antibiotic-resistant gene, NDM-1, was first identified in 2008 a Swedish patient that had received hospital care in New Delhi. NDM-1 produces an enzyme that allows bacteria to destroy most antibiotics. It exists on plasmids, which are pieces of genetic material that are easily shared between bacteria including E coli and other species that can cause pneumonia, urinary tract infections, and blood stream infections.
NDM-1 probably evolved in parts of India where poor sanitation and overutilization of antibiotics provide a perfect environment for the creation of antibiotic-resistant bacteria.
The gene has been identified in three U.S. patients. All had received medical treatment in India, and all recovered from their infections. It has been found sporadically in Britain, Australia and nearly a dozen other countries as well. Most affected patients were “medical tourists” — that is, people seeking less expensive medical care in India.
“We need to be vigilant about this,” said Arjun Srinivasan, an epidemiologist at the CDC told the Washington Post. “This should not be a call to panic, but it should be a call to action. There are effective strategies we can take that will prevent the spread of these organisms.” Read more »
