8 Drugs Doctors Would Never Take
If they won't use these medications, why should you?
By Morgan Lord, Men's Health
With 3,480 pages of fine print, the Physicians' Desk Reference (a.k.a. PDR) is not a quick read. That's because it contains every iota of information on more than 4,000 prescription medications. Heck, the PDR is medication — a humongous sleeping pill.
Doctors count on this compendium to help them make smart prescribing decisions — in other words, to choose drugs that will solve their patients' medical problems without creating new ones. Unfortunately, it seems some doctors rarely pull the PDR off the shelf. Or if they do crack it open, they don't stay versed on emerging research that may suddenly make a once-trusted treatment one to avoid. Worst case: You swallow something that has no business being inside your body.
Of course, plenty of M.D.'s do know which prescription and over-the-counter drugs are duds, dangers, or both. So we asked them, "Which medications would you skip?" Their list is your second opinion. If you're on any of these meds, talk to your doctor. Maybe he or she will finally open that big red book with all the dust on it.
Advair
It's asthma medicine... that could make your asthma deadly. Advair contains the long-acting beta-agonist (LABA) salmeterol. A 2006 analysis of 19 trials, published in the Annals of Internal Medicine, found that regular use of LABAs can increase the severity of an asthma attack. Because salmeterol is more widely prescribed than other LABAs, the danger is greater — the researchers estimate that salmeterol may contribute to as many as 5,000 asthma-related deaths in the United States each year. In 2006, similarly disturbing findings from an earlier salmeterol study prompted the FDA to tag Advair with a "black box" warning — the agency's highest caution level.
Your New Strategy
No matter what you may have heard, a LABA, such as the one in Advair, is not the only option, says Philip Rodgers, Pharm.D., a clinical associate professor at the University of North Carolina school of pharmacy. For instance, if you have mild asthma, an inhaled corticosteroid such as Flovent is often all you need. Still wheezing? "Patients can also consider an inhaled corticosteroid paired with a leukotriene modifier," says Dr. Rodgers. This combo won't create dangerous inflammation, and according to a Scottish review, it's as effective as a corticosteroid-and-LABA combo.
Avandia
Diabetes is destructive enough on its own, but if you try to control it with rosiglitazone — better known by the brand name Avandia — you could be headed for a heart attack. Last September, a Journal of the American Medical Association (JAMA) study found that people who took rosiglitazone for at least a year increased their risk of heart failure or a heart attack by 109 percent and 42 percent, respectively, compared with those who took other oral diabetes medications or a placebo.
The reason? While there have been some reports that Avandia use may cause dangerous fluid retention or raise artery-clogging LDL cholesterol, no one is sure if these are the culprits. That's because the results of similar large studies have been mixed. So the FDA has asked GlaxoSmithKline, the maker of Avandia, to conduct a new long-term study assessing users' heart risks. There's only one problem: The study isn't expected to start until later this year.
Your New Strategy
Stick with a proven performer. "I prefer metformin, an older, cheaper, more dependable medication," says Sonal Singh, M.D., the lead author of the JAMAstudy. "Avandia is now a last resort." Dr. Singh recommends that you talk to your doctor about cholesterol-lowering medicines, such as statins or the B vitamin niacin. Swallowing high doses (1,000 milligrams) of niacin daily may raise your HDL (good) cholesterol by as much as 24 percent, while at the same time lowering your LDL and triglyceride levels.
Celebrex
Once nicknamed "super aspirin," Celebrex is now better known for its side effects than for its pain-relieving prowess. The drug has been linked to increased risks of stomach bleeding, kidney trouble, and liver damage. But according to a 2005 New England Journal of Medicine study, the biggest threat is to your heart: People taking 200 mg of Celebrex twice a day more than doubled their risk of dying of cardiovascular disease. Those on 400 mg twice a day more than tripled their risk, compared with people taking a placebo.
And yet Celebrex, a COX-2 inhibitor, is still available, even though two other drugs of that class, Bextra and Vioxx, were pulled off the market due to a similar risk of heart damage. The caveat to the consumer? In 2004, the FDA adviseddoctorsto consider alternatives to Celebrex.
Your New Strategy
What you don't want to do is stop swallowing Celebrex and begin knocking back ibuprofen, because regular use of high doses of nonsteroidal anti-inflammatory drugs (NSAIDs) can lead to gastrointestinal bleeding. A safer swap is acupuncture. A German study found that for people suffering fromchronic lower-back pain, twice-weekly acupuncture sessions were twice as effective as conventional treatments with drugs, physical therapy, and exercise. The strategic needling may stimulate central-nervous-system pathways to release the body's own painkillers, including endorphins and enkephalins, says Duke University anesthesiologist Tong-Joo Gan, M.D. You can find a certified acupuncturist in your area at medicalacupuncture.org/findadoc/index.html.
Ketek
Most bacteria in the lungs and sinuses don't stand a chance against Ketek, but you might not either. This antibiotic, which has traditionally been prescribed for respiratory-tract infections, carries a higher risk of severe liver side effects than similar antibiotics do. "Ketek can cause heart-rhythm problems, can lead to liver disease, and could interact poorly with other medications you may be taking," says Dr. Rodgers. "Unfortunately, it's still available, and although many doctors are aware of the risks, some may still prescribe it without caution." In February 2007, the FDA limited the usage of Ketek to the treatment of pneumonia.
Your New Strategy
Can't imagine catching pneumonia? The last time the Centers for Disease Control and Prevention calculated the top 10 killers of men, this deadly lung infection (along with the flu) came in seventh. Avoid backing yourself into a corner where you might need Ketek by always signing up for your annual flu shot — if you have pneumonia, it'll reduce your risk of dying of the infection by 40 percent. And if you still end up staring at a scrip for Ketek, Dr. Rodgers recommends asking to be treated with one of several safer alternatives, such as Augmentin or the antibiotics doxycycline or Zithromax.
Prilosec and Nexium
Heartburn can be uncomfortable, but heart attacks can be fatal, which is why the FDA has investigated a suspected link between cardiac trouble and the acid-reflux remedies Prilosec and Nexium. In December 2007, the agency concluded that there was no "likely" connection. Translation: The scientific jury is still out. In the meantime, there are other reasons to be concerned. Because Prilosec and Nexium are proton-pump inhibitors, they are both incredibly effective at stopping acid production in the stomach — perhaps too effective.
A lack of acid may raise your risk of pneumonia, because the same stuff that makes your chest feel as if it's burning also kills incoming bacteria and viruses. You may also have an elevated risk of bone loss — in the less acidic environment, certain forms of calcium may not be absorbed effectively during digestion. "The risk of a fracture has been estimated to be over 40 percent higher in patients who use these drugs long-term, and the risk clearly increases with duration of therapy," says Dr. Rodgers.
Your New Strategy
When you feel the fire, first try to extinguish it with Zantac 150 or Pepcid AC. Both of these OTC products work by blocking histamine from stimulating the stomach cells that produce acid. Just know that neither drug is a long-term fix.
"To really cure the problem, lose weight," says Michael Roizen, M.D., chief wellness officer at the Cleveland Clinic and coauthor of YOU: The Owner's Manual. That's because when you're overweight, excess belly fat puts pressure on and changes the angle of your esophagus, pulling open the valve that's supposed to prevent stomach-acid leaks. This in turn makes it easier for that burning sensation to travel up into your chest.
Visine Original
What possible harm to your peepers could come from these seemingly innocuous eyedrops? "Visine gets the red out, but it does so by shrinking blood vessels, just like Afrin shrinks the vessels in your nose," says Thomas Steinemann, M.D., a spokesman for the American Academy of Ophthalmology. Overuse of the active ingredient tetrahydrozoline can perpetuate the vessel dilating-and-constricting cycle and may cause even more redness.
Your New Strategy
If you still want to rely on Visine, at least make sure you don't use too many drops per dose and you don't use the stuff for more than 3 or 4 days. But you'd really be better off figuring out the underlying cause of the redness and treating that instead. If it's dryness, use preservative-free artificial tears, recommends Dr. Steinemann. Visine Pure Tears Portables is a good choice for moisture minus side effects. On the other hand, if your eyes are itchy and red because of allergies, pick up OTC antiallergy drops, such as Zaditor. It contains an antihistamine to interrupt the allergic response but no vasoconstrictor to cause rebound redness.
Pseudoephedrine
Forget that this decongestant can be turned into methamphetamine. People with heart disease or hypertension should watch out for any legitimate drug that contains pseudoephedrine. See, pseudoephedrine doesn't just constrict the blood vessels in your nose and sinuses; it can also raise blood pressure and heart rate, setting the stage for vascular catastrophe. Over the years, pseudoephedrine has been linked to heart attacks and strokes. "Pseudoephedrine can also worsen symptoms of benign prostate disease and glaucoma," says Dr. Rodgers.
Your New Strategy
Other OTC oral nasal decongestants can contain phenylephrine, which has a safety profile similar to pseudoephedrine's. A 2007 review didn't find enough evidence that phenylephrine was effective. Our advice: Avoid meds altogether and clear your nasal passages with a neti pot, the strangely named system that allows you to flush your sinuses with saline ($15, sinucleanse.com). University of Wisconsin researchers found that people who used a neti pot felt their congestion and head pain improve by as much as 57 percent. Granted, the flushing sensation is odd at first, but give it a chance. Dr. Roizen did: "I do it every day after I brush my teeth," he says.

Aspartame: Tropicana Slim, Equal, NutraSweet, Canderel, Splenda
Pare leer este artículo en español oprima aquí.
Something to know about nutrition regarding: Aspartame, Tropicana Slim, Equal, NutraSweet, Canderel, Splenda, Saccharin. These might not be the healthy alternative that most people expect them to be. They are documented to cause health problems like cancer and even increase obesity.
According to Wikipedia "Formaldehyde - based solutions are used in embalming to disinfect and temporarily preserve human remains." So happens that "Approximately 10% of aspartame (by mass) is broken down into methanol in the small intestine."
From the Doorway to Discovery, explains how it happens
How it happens: Methanol, from aspartame, is released in the small intestine when the methyl group of aspartame encounters the enzyme chymotrypsin (Stegink 1984, page 143). Free methanol begins to form in liquid aspartame-containing products at temperatures above 86 degrees F.. also within the human body.
The methanol is then converted to formaldehyde. The formaldehyde converts to formic acid, ant sting poison. Toxic formic acid is used as an activator to strip epoxy and urethane coatings. Imagine what it does to your tissues!
Phenylalanine and aspartic acid, 90% of aspartame, are amino acids normally used in synthesis of protoplasm when supplied by the foods we eat. But when unaccompanied by other amino acids we use [there are 20], they are neurotoxic.
That is why a warning for Phenylketonurics is found on EQUAL and other aspartame products. Phenylketenurics are 2% of the population with extreme sensitivity to this chemical unless it’s present in food. It gets you too, causing brain disorders and birth defects! Finally, the phenyalanine breaks down into DKP, a brain tumor agent.
In other words: Aspartame converts to dangerous byproducts that have no natural countermeasures. A dieter’s empty stomach accelerates these conversions and amplifies the damage. Components of aspartame go straight to the brain, damage that causes headaches, mental confusion, seizures and faulty balance. Lab rats and other test animals died of brain tumors.
Artificial sweetners are generally used to loose weight. If so, it should be of interest to learn the following:
Artificial sweetners including sucralose have been identified as possible factors in raising population obesity levels by making the consumer take up more calories later, because it confuses the brain and body responses about sugary substances and calories - associating sweet foods with fewer calories.[34]

Can Vitamin D Save Your Life?
New studies highlight the importance of the forgotten vitamin.
by Mariana Gosnell
For years doctors believed that vitamin D, sometimes called the “sunshine vitamin” because sunlight triggers the body to produce it, was important primarily in preventing rickets (a softening of the bones) in children. Once milk became fortified with vitamin D, rickets pretty much disappeared, and the problem of vitamin D deficiency seemed to have been solved. But according to Michael F. Holick, director of the Vitamin D, Skin, and Bone Research Laboratory at Boston University Medical Center, who has spent 30 years studying the vitamin, “rickets can be considered the tip of the vitamin D–deficiency iceberg.”
Today a lack of the vitamin has been linked to a host of other maladies, including cancers of the colon, prostate, and breast; tuberculosis; schizophrenia; multiple sclerosis; hip fractures; and chronic pain. How can one vitamin play a role in so many diverse illnesses? The answer seems to lie in the fact that most tissues and cells in the human body (and not just those in the intestine and bone that help fix calcium) have receptors for vitamin D, suggesting that the vitamin is needed for overall optimal health. In addition, some cells carry enzymes for converting the circulating form of vitamin D to the active form, making it available in high concentrations to the tissues locally.
A recent laboratory experiment at Boston University revealed that by activating the circulating form of the vitamin, prostate cells could regulate their own growth and possibly prevent the rise of cancer. Directly or indirectly, Holick points out, “the active form of vitamin D controls up to 200 different genes,” including ones responsible for cell proliferation, differentiation, and death.
Theories about vitamin D’s cancer-prevention qualities have begun to be validated. In June, Joan M. Lappe, professor of nursing and medicine at Creighton University School of Medicine in Omaha, and her colleagues published the results of a 4-year, double-blind, randomized trial in which nearly 1,200 healthy postmenopausal women took calcium alone, calcium with 1,100 international units (IU) of vitamin D a day, or a placebo. The women who took calcium with vitamin D had a 60 percent lower risk of developing cancers of any type than the placebo group; the calcium-only group’s risk didn’t significantly change.
Currently, the median vitamin D intake of adult Americans is only about 230 IU a day; Lappe was prompted by the study’s findings to recommend the dose be increased to 1,500 to 2,000 IU. “It’s low risk, with maybe a high payoff,” she told a Canadian newspaper in June. Vitamin D comes from three sources: the sun’s ultraviolet (UVB) rays penetrating the skin, a few D-rich foods like fatty fish and some fortified foods, and supplements. The Canadian Paediatric Society has already recommended that pregnant or breast-feeding women get 2,000 IU of vitamin D daily.
Some clinicians have suggested that increased vitamin D intake might help ward off multiple sclerosis (MS), believed to be a progressive autoimmune disease. Last December, a team of researchers at the Harvard School of Public Health and other institutions published results from the first large-scale prospective study of the relationship between vitamin D levels and MS. After analyzing stored blood samples taken from 7 million military personnel and identifying those individuals who developed MS during a 12-year period, the team determined that the risk of getting MS was 62 percent lower for those whose blood concentration of vitamin D put them in the top quintile than for those in the bottom quintile. The study did not make clear, however, whether low vitamin D levels were a cause of MS or a marker of MS risk.
Vitamin D status may also affect vulnerability to infections. For example, African Americans need more sun exposure than Caucasians to make sufficient vitamin D; they also suffer from increased risk of tuberculosis. In a breakthrough study published in March, scientists from several institutions, including UCLA, discovered a possible link. On encountering the TB bacillus, receptors on immune-system scavenger cells known as macrophages stimulate the conversion of circulating vitamin D to its active form, which produces a peptide that destroys the bacillus. If circulating levels of D are low, macrophages can’t activate the vitamin D to initiate this response. A similar scenario could be operating with other infectious agents, maybe even the influenza virus.

May 19 2008 Scotland, The island house that powers itself - with a little help from 100mph gales
Pare leer este artículo en español oprima aquí .
Photo and text below are excerpts from the article published by The Guardian. Should pay close attention to this type of home building because it is the way of the future. The attention being paid by the Chinese could be a key to develop low cost equipment used in building green homes. Note the concept of carbon-constrained future as a most recent level of measurement.

Life on the most northerly inhabited island in Britain can be very tough indeed. On Unst the winters are harsh, and the winds brutal and relentless, regularly sweeping across the treeless landscape at more than 100mph.
But Unst is the island chosen by a retired couple from Wiltshire to build one of the world's greenest houses - a "zero carbon" home powered entirely by the wind and the sun. It sits on the same latitude as southern Greenland, but will soon boast lemon trees, grapevines and green pepper plants in its greenhouse, an electric car powered by the wind, and floors heated by drawing warmth from the air.
The three-bedroom home designed by Michael and Dorothy Rea, near the shoreline of a secluded bay, has become a test bed for living "off-grid": generating all their power from renewable sources, growing most of their food at home, and running a car without a petrol station.
Their home - built for just over £210,000 from an off-the-shelf timber framed house - has quietly become famous. The Scottish executive in Edinburgh is using it as a benchmark for new sustainable house-building rules; officials in the prime minister's office watch its progress and Chinese officials are studying its innovative technologies for a new 5,000-home eco-town in Guangzhou, in southern China.
Last year, the Reas learned that their website - zerocarbonhouse.com - was the fourth most popular site worldwide on Google. Michael Rea is often up at 5am answering emails from PhD students, green activists and even Canadian senators.
...
"It's definitely significant," said Duncan Price, a director of one of the world's largest green energy consultancies, ESD, and an advisor to the Reas. "What's very special is they're trying to address the carbon impact of their whole lifestyle. It's a microcosm of how the world would be in a carbon-constrained future."
...
Around 80 people living on Scoraig, which is only accessible by boat or with a five-mile trek overland, power their homes and businesses chiefly using small hand-made wind turbines designed by local resident Hugh Piggott, a guru of self-sufficient off-grid living. Solar panels and diesel generators supplement the turbines.
In February, the islanders of Eigg, just south of Skye, switched on the UK's first independent "green grid". It provides power to all the 45 homes and 20 businesses by combining electricity from wind turbines, solar panels and two small hydro-electric dams into a single supply. For the first time, islanders can run fridges, electric kettles, satellite TVs and computers without using unreliable oil-powered generators.
Forced by their isolation to become self-sufficient, many observers believe these communities prove that micro-generation and home energy schemes are viable UK-wide. Nick Rosen, author of How to Live Off-Grid, a handbook on off-grid communities, said: "It doesn't mean we should all live like Scoraig but we should be fostering communities like it all over the place. It increases the self-reliance of our society overall, in the event of sudden energy price hikes, the Russians cut off the gas or strikes in the oil industry."
...
With help from Dundee University and Duchy College in Cornwall, they are building a greenhouse which uses hydroponics where their vegetables, fruit and herbs will be grown in a liquid with specially controlled lighting to create artificial "seasons". The University of Delaware is refitting a Toyota Yaris car with an electric engine.
...
The house is very heavily insulated and its under-floor heating uses warmth drawn from the outside air and stored in a giant "water battery". Heat inside the house is captured by a ventilation system and reused. Rainwater is harvested for toilets and the washing machine. Large windows capture warmth from the sun.
Power for dishwasher, cooker, toaster, fridge, computers and lights comes from a wind turbine, which charges fuel cells able to store power for four days. The house's LED lights will use the same power as one 100W bulb.
The greenhouse will have its own wind turbine. Plants will grow in high-nutrient hydroponic liquids, with special LED lights to create artificial seasons and daylight. A converted battery-powered Toyota Yaris will be charged from the fuel cells.
