Did you know that common over-the-counter drugs or prescriptions can cause memory loss and cognitive impairment?

Mild cognitive impairment is a common, age-linked condition that is often an early sign of Alzheimer's disease. Its cardinal symptom is forgetfulness or impairment of short-term memory.

Numerous drugs have been shown to produce mild cognitive impairment (MCI). They may create or aggravate Alzheimer's-type symptoms.

(NOTE: You should NOT stop taking medications without first consulting your physician.)

Most of the drugs that cause MCI have a property called "anti-cholinergic." They inhibit activity of the neurotransmitter acetylcholine, which plays a critical role in memory and cognitive function.

Why a Food's Glycaemic Load is a Better Measure Than its Carbohydrate Content

© eglycemicindex.comThe glycemic index, or GI, ranks carbohydrates on a scale from 0 to 100 according to their effect on blood sugar levels.
When glucose (a sugar) is absorbed from the gut into the bloodstream, a healthy pancreas will secrete the hormone insulin in response. One chief effect of insulin is to reduce blood sugar levels by facilitating the transfer of sugar into the body's cells. This is a critically important function, and without it sugar levels can rise to dangerously high and even fatal levels. Insulin is essential to life. But, as is the way, we can always get too much of a good thing. In the long term, high levels of insulin can predispose the body to a range of health issues including obesity, heart disease and type 2 diabetes.

With this in mind it does make sense to avoid eating much in the way of foods that disrupt blood sugar, and therefore insulin, levels.

The 'macronutrient' most renowned for its effect on blood sugar is carbohydrate - a term that encompasses sugars and starch. Much of the sugar and starch we consume in our diets is digested down to glucose prior to absorption.

Study links hypoxia and inflammation in many diseases


University of Colorado Denver
Fri, 18 Feb 2011 14:55 UTC
University of Colorado researchers focus on how the body adapts.

When the body is deprived of oxygen during a major surgery, the kidneys, heart muscles or lungs can be injured as a result. The problem is that lack of oxygen can lead to inflammation.

Yet some athletes deliberately train at high altitude, with less oxygen, so they can perform better. Their bodies adapt to the reduced oxygen.

Now a doctor at the University of Colorado School of Medicine has explored the relationship between lack of oxygen, called hypoxia, and the inflammation that can injure or kill some patients who undergo surgery. In a liver transplant, for example, the surgery and anesthesiology can go perfectly yet the new liver will fail because of hypoxia.

"Understanding how hypoxia is linked to inflammation may help save lives of people who have survived a major surgery only to be faced with potential harm to major organs," says Holger K. Eltzschig, MD, PhD.

Many agricultural pesticides disrupt male hormones, according to new tests.

Many agricultural pesticides - including some previously untested and commonly found in food - disrupt male hormones, according to new tests conducted by British scientists.

The scientists strongly recommended that all pesticides in use today be screened to check if they block testosterone and other androgens, the hormones critical to a healthy reproductive system for men and boys.

"Our results indicate that systematic testing for anti-androgenic activity of currently used pesticides is urgently required," wrote the scientists from University of London's Centre for Toxicology, led by Professor Andreas Kortenkamp.

Thirty out of 37 widely used pesticides tested by the group blocked or mimicked male hormones. Sixteen of the 30 had no known hormonal activity until now, while there was some previous evidence for the other 14, according to the study, published online last Thursday in the scientific journal Environmental Health Perspectives.

FDA Report: Alarming Amounts of "Superbugs" in Supermarkets

A federal government report on antibiotic resistance reveals that superbugs in meat is a much more common and widespread problem than anyone would like to admit. New strains of hearty, antibiotic resistant salmonella, E. coli and campylobacter bacteria appear to be showing up in alarmingly high percentages of the chicken, turkey, pork and beef we buy at the supermarket.

These findings come from a little-noticed report the FDA released back in December. The report, which was dumped onto the FDA's web site without so much as a mention or a press release, compiles data from 5,236 samples of chicken breasts, ground turkey, ground beef and pork chops that were taken in 2008. It's unclear why the FDA either waited or took so long to release the info.

On her blog, Maryn McKenna, author of a book about antibiotic resistance called Superbug and the first person to write about the report, summarized some of the findings: In 2008, 45% of salmonella on chicken were resistant to the antibiotic tetracycline and 30% were immune to penicillins. Among enterococci bacteria on chicken, 65% were resistant to tetracycline and more than 90% to lincosamides, which include the everyday drug clindamycin.

Best of the Web: Why Almost Everything You Hear About Medicine Is Wrong

If you follow the news about health research, you risk whiplash. First garlic lowers bad cholesterol, then - after more study - it doesn't. Hormone replacement reduces the risk of heart disease in postmenopausal women, until a huge study finds that it doesn't (and that it raises the risk of breast cancer to boot). Eating a big breakfast cuts your total daily calories, or not - as a study released last week finds. Yet even if biomedical research can be a fickle guide, we rely on it.

But what if wrong answers aren't the exception but the rule? More and more scholars who scrutinize health research are now making that claim. It isn't just an individual study here and there that's flawed, they charge. Instead, the very framework of medical investigation may be off-kilter, leading time and again to findings that are at best unproved and at worst dangerously wrong. The result is a system that leads patients and physicians astray - spurring often costly regimens that won't help and may even harm you.

It's a disturbing view, with huge im-plications for doctors, policymakers, and health-conscious consumers. And one of its foremost advocates, Dr. John P.A. Ioannidis, has just ascended to a new, prominent platform after years of crusading against the baseless health and medical claims. As the new chief of Stanford University's Prevention Research Center, Ioannidis is cementing his role as one of medicine's top mythbusters. "People are being hurt and even dying" because of false medical claims, he says: not quackery, but errors in medical research.

Comment: While it is true that being morbidly obese or severely underweight can shorten a lifespan, the jury properly should still be out on smoking. In fact, if Dr. Ioannidis' principles were applied to smoking studies, it's likely that 99% of them would have to be thrown out.

Johnson & Johnson is recalling 70,000 syringes preloaded with its Invega injectable anti-psychotic drug, the WSJ reports. Cracks have been found in the syringes that could theoretically lead to infections or under-dosing in users of Invega Sustenna, though the company said that risk is low. (One report of an adverse event in Australia may be linked to the problem.)

We've been keeping tabs on J&J's string of recalls, which cost it about $900 million in sales last year. Here's a running list:

Dr. Maurice Hilleman made astounding revelations in an interview that was cut from The Health Century -- the admission that Merck drug company vaccines had been injecting dangerous viruses into people worldwide.

Bear in mind that Dr. Hilleman was the developer of Merck's vaccine program. He developed over three dozen vaccines, more than any other scientist in history. He was a member of the U.S. National Academy of Science, the Institute of Medicine, the American Academy of Arts and Sciences, and the American Philosophical Society. He received a special lifetime achievement award from the World Health Organization. Hilleman was one of the early vaccine pioneers to warn about the possibility that simian viruses might contaminate vaccines.

A spike in global food prices has pushed millions more into poverty since last summer, said World Bank president Robert Zoellick

The World Bank has given a stark warning of the impact of the rising cost of food, saying an estimated 44 million people had been pushed into poverty since last summer by soaring commodity prices.

Robert Zoellick, the Bank's president, said food prices had risen by almost 30% in the past year and were within striking distance of the record levels reached during 2008.

"Global food prices are rising to dangerous levels and threaten tens of millions of poor people around the world," Zoellick said. "The price hike is already pushing millions of people into poverty, and putting stress on the most vulnerable, who spend more than half of their income on food."

South Korea fighting uphill battle against foot-and-mouth disease millions of cows and pigs have been culled

Jiongchiri, South Korea-- More than 140 cases of foot-and-mouth disease (FMD) have been confirmed nationwide in South Korea and millions of cows and pigs have been culled, but Lim Kang-soo never believed his cows could fall victim to this highly contagious animal disease.

Lim, a resident of Jeongchiri near Gongju in South Chungcheong Province, confidently invested his life savings into a small cow farm, believing in its notoriously strict vaccination policies -- until eight of his cattle tested positive for FMD last month.

"We sterilized ourselves head to toe whenever we stepped in and out of the shed," Lim said."Our village is tucked away deep in the hills, 60 kilometers away from the closest FMD case. How could this have happened?"

An independent investigation, commissioned by the Icheon municipality west of Seoul and released last week, gave weight to the argument that transmission by air and not direct contact might have been the primary force behind the rapid spread of the lethal airborne virus.
