SIDS is the sudden death of an otherwise healthy infant that can't be attributed to any other cause. It may be caused by brain abnormalities that prevent babies from gasping and waking when they don't get enough oxygen.

Researchers interviewed mothers of 185 infants who died from SIDS, and mothers of 312 infants of similar race and age. The mothers answered dozens of questions about their baby's sleeping environment. Researchers found that fan use was associated with a 72 percent lower risk of SIDS.

However, placing babies on their backs to sleep is still the best advice for preventing SIDS. Experts also recommend a firm mattress, removing toys and pillows from cribs, and keeping infants from getting too warm.

Biologists have shown that a functioning circadian system is critical to hamsters' ability to remember what they have learned. Without it, in fact, they can't remember anything.

Hamsters whose circadian system was disabled consistently failed to remember their environment, unlike hamsters with normally functioning circadian systems.

Until now, it has never been shown that the circadian system is crucial to learning and memory. The change in learning retention appears to hinge on the amount of a neurochemical called GABA, which the circadian clock uses to control the daily cycle of sleep and wakefulness.

The study looked at data from more than 190,000 children in 28 countries. Their parents responded to questionnaires about various health and diet practices. After controlling for numerous factors, the study showed that children given acetaminophen before age 1 had an almost 50 percent increased risk for asthma, eczema and allergy.

The study is large, but the conclusion is not certain; the medical information was obtained from parents after the fact, and children with asthma and related illnesses may be more likely to be treated with acetaminophen in the first place.

A $5,000 genome would enable new studies to identify rare genetic variants linked to common diseases, and could open up the sequencing market to diagnostic and pharmaceutical companies. It could make genome sequencing a routine part of clinical drug testing.

Complete Genomics anticipates the capacity to sequence 1,000 genomes in 2009 and 20,000 in 2010. That would represent a massive jump; only a handful of human genomes have been sequenced to date.

Complete Genomics says that its cheap price tag comes thanks to two innovations: a way to densely pack DNA and a method to randomly read DNA letters. First, an 80-base-pair piece of DNA is inserted into a circular piece of synthetic DNA and replicated 1,000 times with a specialized enzyme. That large aggregate of DNA compresses into a tightly packed ball, and these DNA "nanoballs" are then packed onto specially fabricated arrays. The high density of DNA allows large volumes to be sequenced quickly with few reagents, one of the most costly components of the process.

Next, Complete Genomics determines the sequence of the target DNA using a series of fluorescently labeled DNA strands designed to bind to corresponding letters. But while sequencing technologies currently in use read the sequence sequentially, letter by letter, Complete Genomics' labels bind to the target DNA randomly. But the labels are designed to allow scientists to deduce the position of each highlighted base, which allows a computer to reconstruct the sequence of the target DNA.

One study revealed that flu shots in the past two seasons did not reduce doctor visits or the risk of hospitalization for flu in children age 5 and younger. Another showed that MRSA, or methicillin-resistant Staphylococcus aureus (a sometimes fatal drug-resistant bacteria that can accompany the flu), as opposed to the flu itself, is a main contributor to the growing number of child deaths attributed to influenza.

The first study suggested that a reason the vaccine did not prevent children from getting the flu was that the strains in the flu vaccines have mismatched the circulating flu strain in past years.

MRSA is a drug-resistant superbug that can piggyback on the flu and can cause outbreaks of deadly pneumonia. Secondary infections increase the risk of death from the flu more often than the flu itself.

White fat cells store energy and produce hormones that are secreted into the blood. They release adiponectin, which actually helps to fight diabetes, heart disease and other diseases. But in obese people, fat cells tend to shut down the production of adiponectin, which has negative effects on health.

While a white fat cell stores energy, a brown fat cell's job is basically to generate heat. There is increasing evidence that some humans, particularly those who are lean, tend to have more brown fat cells mixed in with their white fat cells in some regions of their body.

If the body could be persuaded to make more brown fat cells, it could help fight the tendency to gain excess weight.

Country of origin labels will now be on beef, pork, lamb, chicken, goat meat, perishable agricultural commodities, peanuts, pecans, ginseng, and macadamia nuts. For safety advocates it is a huge step forward.

"It's vitally important to ensure that products coming in from other countries as well as ones growing here are quickly identified in an outbreak," says Caroline Smith DeWaal, Director of Food and Safety Center for Science in the Public Interest.

But some food safety advocates say country of origin labeling is not specific enough, and say that labels should contain bar codes that can automatically trace foods all the way back to the farm.

In recent years, dermatologists have begun to see an increasing number of contact dermatitis patients who are allergic to their cell phones -- or more specifically the nickel in their cell phones.

Chairs, Flutes and Other Items With Nickel

The unexpected allergic reactions to nickel don't stop at cell phones. The number of allergy patients testing positive for a nickel reaction is on the rise in the United States. Many clinicians have attributed the increase, especially in men, to a growing number of ear and other piercings.

Black Henna Tattoos

For thousands of years, people in North Africa, the Middle East and South Asia have decorated their bodies with henna, but in recent decades, adulterations in the dye used for these temporary tattoos have resulted in painful allergic reactions.

Allergic to Dad?

40 percent of food allergy reactions come not from eating a food trigger but from touching or inhaling it. Such was the case with one young girl who developed hives after she hugged and kissed her father when he returned home from work. She was allergic to the nut-derived oil in her father's shaving cream.

Chocolate

Most reactions to chocolate either are not true allergic reactions or they come as a result of exposure to nuts or milk in the chocolate chunks. But some people truly are allergic to chocolate.

Exercise

A rare condition called exercise-induced anaphylaxis can result in an allergic reaction during exercise, and it can be severe enough to kill the exerciser.

Hot and Cold

About one in five people will develop hives at some point in their lives, but a much smaller number will get physical urticarias (urticaria is another word for hives) when they contact or experience some very ordinary things. If you put an ice cube on somebody that has cold urticaria, they get a welt right where the ice cube was. Urticarias can also sometimes be set off by heat, sunlight, vibration, or pressure.

Hairy Caterpillars

The pine processionary caterpillar and its cousin, the oak processionary caterpillar, look harmless enough, but the hairs that cover their bodies contain a toxin that can cause a serious allergic reaction. Add to that the fact that those hairs can sail right off the caterpillar like dandelion seeds, and you have an airborne allergen not unlike pollen.

Asian Ladybugs

In recent years, researchers have pegged these beetles as a source of allergic symptoms including hay fever, coughing, wheezing and watery eyes. Asian ladybugs, formally known as multicolored Asian lady beetles, were introduced to the U.S. as early as 1916 to control the aphid population, but the beetles don't like the cold, so they regularly swarm into houses when the temperature drops.

Cancer Drugs

Sometimes, a drug sparks an allergic reaction that can kill. In the case of cetuximab, also known as Erbitux, an intravenous drug given to people with colon cancer as well as head and neck cancer, there was an unusually high rate of allergic reactions. It may be caused by an antibody developed in response to a seed tick bite.

A systematic review of the efficacy of probiotics in IBS that included 19 randomized controlled trials found that "probiotics are effective in IBS,” although there was not enough information to be sure whether one probiotic is particularly effective or whether combinations of probiotics are required.

In a separate study conducted at seven pediatric GI centers in the United States, Italy, and India, researchers found that probiotics were safe and significantly more effective than the placebo in alleviating IBS-related symptoms in children and teenagers.

Here, then, are ten common beliefs about productivity that keep people from enjoying the success they desire.

Myth 1: Organized Equals Clean

Too many people equate “organization” with the cold, sterile, un-lived-in spaces they see in glossy magazines. But an organized space is simply one in which the things you need the most are close at hand, the things you need often are easily found, and the things you need rarely are out of the way but easily retrieved when needed. That means that organization has to meet your needs, not some imposed notion of cleanliness.

Myth 2: I Don’t Have Time for a System

The thinking goes something like this: “If I spend all my time maintaining my list and doing weekly reviews, I’ll never get anything done.” The reality is that while most systems take some time to get set up, once you start using your system, the time you use in “maintenance” is more than made up for by the time you save not having to think about what to do.

Myth 3: Systems are Rigid and Inflexible

If your life is so chaotic and unpredictable that it seems like no system could solve it, it’s likely that its because you’ve resisted adopting some kind of system, rather than because no system is good enough.

Myth 4: Productivity Means More Work

Once you start down this rabbit hole, it can be really hard to turn yourself around. But productivity isn’t just about work. Being more productive in your life means you should have more time to do things like spend time with your family, take a vacation, read a book, visit a museum, or write your plan for world domination. Getting your work done in half the time just so you can do twice as much work isn’t productive -- it’s dumb.

Myth 5: Creativity Can’t Be Fit Into a System

Maybe you believe that productivity stuff is for business people, not creative people. But creative work is still work, and just as susceptible to procrastination, poor planning, and shoddy work practices as bookkeeping, house painting, and world domination. And while you may have a great grasp of the demands of your creative work, records need to be kept, clients need to be contacted, taxes need to be filed, and projects need to be invoiced.

Myth 6: I Work Best Under Pressure

There are people who believe they thrive under the pressure of an impending deadline. Nine times out of ten, they don’t. They just enjoy the excuse because it means they don’t have to take responsibility for the messes they end up in. Keeping yourself in a high-stress, always-urgent mode isn’t good for your health, and it’s not good for your business.

Myth 7: My Lack of a System Is My System

This one’s actually true, though not in the way most people intend when they say it. The mess of habits, practices, and beliefs you have right now are, in fact, a system -- and you’re working it every day. But what most people mean is that by not having a system, they’re actually being more productive than if they had a system. They think that the mish-mash of habits they’ve cobbled together out of life experience is working for them. They don’t see any room for improvement -- but there’s always room for growth.

Myth 8: I Need Inspiration to Work

No, you don’t. Inspiration is wonderful, but rarely compatible with getting stuff done. What you need is a system to capture those flashes of inspiration so that, when inspiration is on holiday, you’ve got plenty to work with.

Myth 9: Being Organized is Boring

This myth is misguided because it places attention in the wrong place. Being organized isn’t boring -- being boring is boring. Make your own excitement and you’ll stop being boring. Then you can stop using your disorganization as a crutch for a life not fully realized.

Myth 10: There’s Something Wrong With Me No System Can Fix

This one’s could be true. Systems, no matter how good, can’t fix the fundamental problems in your life. They won’t make you smarter or more likable or better looking or more experienced. What they can do is help you make time to figure out how to solve those problems. They can help you make a space in your life for real personal growth. And they can help you highlight the sources of those failures. In the end, your growth as a person, your success -- however you define it -- is up to you.

The researchers thought this could meant that vitamin D replacement might prevent osteoporosis and other bone complications related to end stage liver disease.

The study included 43 hepatitis C patients with cirrhosis, 57 hepatitis C patients without cirrhosis, and 18 cirrhosis patients without hepatitis C.

The study analyzed an in-depth survey conducted in 2004 by the Centers for Disease Control and Prevention that asked people how they got health care. Children in the lowest income group were no more likely to receive the samples than were those in the highest income group, in part because the poor are less likely to see doctors. Once in a doctor’s office, however, children who lack health insurance are more likely to receive free drug samples than their well-insured counterparts.

But the drugs provided as free samples tend to be the newest varieties, so their safety has often not been thoroughly vetted. In 2004, the year of the CDC survey, more than 500,000 children received samples of four medicines that were later the subject of serious safety warnings required by the Food and Drug Administration: Advair, for asthma; Adderall and Strattera, for attention deficit disorder; and Elidel, for eczema.

Elidel was given to the parents of more than 38,000 children under age 2. The FDA later received reports of skin cancer in patients who took Elidel.

The study found that supplemental vitamin D appeared to correct a defect in the immune systems in patients with this skin disease. The researchers studied a small number of patients with moderate to severe atopic dermatitis.

It has previously been shown that defects in the immune system interfere with the skin's ability to produce a peptide called cathelicidin, which is protective against microbial invasion. Study participants were all given 4000 IUs of oral Vitamin D3 (cholecalciferol) per day for 21 days. The researchers found that oral vitamin D use by the patients appeared to correct the skin's defect in cathelicidin.

This is a huge change. Previously, flu vaccine was recommended only for youngsters under 5, who can become dangerously ill from influenza. This year, the government is recommending that children from age 6 months to 18 years be vaccinated, expanding inoculations to 30 million more school-age children.

The government argues that while older children seldom get as sick as the younger ones, it's a bigger population that catches flu at higher rates, so the change should cut missed school, and parents' missed work when they catch the illness from their children.

Of course, this policy ignores the fact that a systematic review of 51 studies involving 260,000 children age 6 to 23 months found no evidence that the flu vaccine is any more effective than a placebo. And possible serious adverse reactions to flu shots include joint inflammation and arthritis, anaphylactic shock (and other life-threatening allergic reactions), and Guillain-Barré syndrome, a paralytic autoimmune disease.

Doesn’t sound like such a great idea after all, now does it?

1. Self-Help Selfishness

One of the potential dangers of constantly working on you is that you can inadvertently become self-absorbed, selfish, unaware of the needs of others and disconnected from reality. Some Personal Development devotees are so ’self-focused’ (their world, their issues, their problems, their relationships, their body, their finances) that they struggle to relate to, take an interest in, and connect with people who don’t have the same mindset, values, attitudes or thinking.

2. The Self-Help Evangelist

If you really want to alienate people, point out all their faults, show them the error of their ways, demonstrate how clever you’ve become on your self-help journey and do your best to convert them to your Religion. After all, it’s for their own good right?

3. Theory Isn’t Reality

There’s a lot of space between knowing what to do and doing what we know. Far too many people are champions at the knowing part but completely useless when it comes to the doing.

4. Guru Worship

By all means, respect people (if they deserve it) but don’t worship them. Instead of empowering themselves, some people actually empower their Guru and turn them into a demi-god.

5. It’s Expensive

Make sure you get a good return on your investment and know what you’re buying. Spend your self-help money wisely and thoughtfully.

6. Some of It’s Useless

Some personal development material is not practical, not realistic and doesn’t change lives over the long term. Some writers and speakers are more concerned with making friends and winning fans than speaking the truth, no matter how popular or unpopular that message may be.

7. Creating Life-Long Results is About You

All the personal development resources in the world can’t change your life one bit. The only thing that can change your life forever is YOU.

A single serving of 11 popular cereals, including Kellogg's Honey Smacks, can carry as much sugar as a glazed doughnut. And some brands have even more sugar and sodium when formulated for the U.S. market than the same brands have when sold in other countries.

Post Golden Crisp and Kellogg's Honey Smacks are both more than 50 percent sugar by weight, while nine brands are at least 40 percent sugar.

1. Eliminate the Enemy.

The single most important thing you can do is make sure that you do not have the following in your home; bread, potatoes, pasta, chips, savory snacks, cakes, cookies, sweets, candies, chocolates and sugary drinks. This sounds severe but if you can remove these items you remove the temptation and opportunity to consume them.

2. Eat Plenty.

Eat plenty of good foods vegetables, fruit, lean meats, cheese and eggs.

3. Eat Out Less.

It is possible to find good items on the menu, but generally it is much harder to resist temptation when eating out -- so eat at home more.

4. Leave the Car on the Driveway.

Try to walk or cycle for local outings.

5. Play Tennis.

Or any other vigorous exercise.

6. Do it With Your Partner.

It is much easier to change your lifestyle and remove tempting bad foods from the home if your family are all involved. Try to make it a joint effort.

The giant coffee chain has a policy of keeping a tap running non-stop at all its 10,000 outlets worldwide, more than 6 million gallons a day. That would provide enough daily water for the entire population of drought-stricken Namibia in Africa, or fill an Olympic pool every 83 minutes.

Every Starbucks branch has a cold tap behind the counter providing water for a sink called a “dipper well”, used for washing spoons and utensils.

Biocides are commonly used in cleaning hospitals and home environments, sterilizing medical equipment and decontaminating skin before surgery. At the correct strength, biocides kill bacteria and other microbes. But if lower levels are used, the bacteria can survive and become resistant to treatment.

Researchers exposed S. aureus taken from the blood of patients to low concentrations of several biocides. Exposure to low concentrations of a variety of biocides resulted in the appearance of resistant mutants.

According to the fascinating article linked below, it might help to consider American health as a house. Health care is the -- very expensive -- roof, the final protection against illness. In some ways it’s a preventive system, but mostly it’s sickness care.

In most other countries, the roof is a simpler affair. These health care systems rely much more on prevention. Yet the people in those “houses” live longer, healthier lives. That’s because in those other countries, the foundation and the walls of the house are stronger, with fewer cracks to let in the cold.

Start with the foundation. That’s the head start toward health that children in most other rich countries receive. In part because of better pre-natal care, infant mortality in all other industrial countries is lower than in the United States, which ranks 42nd in the world.

In every country in the world except the United States, Liberia, Swaziland and Papua New Guinea, mothers, and often, fathers, are guaranteed paid time off from work to take care of newborns. In many cases, such “family leave” extends for up to a year or more.

The first wall is lifestyle. Our tax system subsidizes producers of sugars and fats and our marketing system relentlessly advertises unhealthy foods. At the same time, Americans tend to work longer hours than people in other rich countries.

Wall number two is stress relief. It’s no secret in the field of public health that stress is a killer. Several factors make American life particularly stressful. Stress can result from insecurity. As the American social safety net has been gutted in recent years and job protections have been reduced, life in America is far more insecure than in other rich countries. Stress is also the result of time pressures and overwork. Breaks from a stressful workplace are seen by Europeans as yet another way to improve health.

The third wall is social connection. It’s a given in the field of public health that social connection strengthens immune systems and improves physical well-being. Yet America is an increasingly lonely country. More and more people, and especially older Americans, live alone, far more than in other rich countries. A recent study found that the average American has only two close friends he or she can turn to. A quarter have none at all.

The fourth wall is a safe environment. Americans rank at the bottom in child safety, with the highest rates of accidents among children. Partly, time pressure on American parents leave them less able to supervise their children. Other studies show extremely high rates of accidents in the workplace compared to other nations. Finally, and this is no small matter, every other industrial country guarantees its workers paid time off from work when they are sick; only the U.S. does not. Those countries know that without paid time off, workers will come to work sick, and will get others sick and stay sick longer.

To achieve better health outcomes, Americans must begin to see health as a holistic matter. Right now the American health care “house” has a foundation that is part marble, part rotting wood and part dirt. It has four walls that are a mixture of teak, balsa wood and bamboo, all of them in sorry shape. And finally, it has a gilded roof with millions of holes.

But a Group Health study found that flu shots do not protect elderly people against developing pneumonia -- the primary cause of death resulting as a complication of the flu. Others have questioned whether there is any mortality benefit with influenza vaccination. Vaccination coverage among the elderly increased from 15 percent in 1980 to 65 percent now, but there has been no decrease in deaths from influenza or pneumonia. A systematic review of 51 studies involving 260,000 children age 6 to 23 months found no evidence that the flu vaccine is any more effective than a placebo.

There is some evidence that flu shots cause Alzheimer’s disease, most likely as a result of combining mercury with aluminum and formaldehyde. Mercury in vaccines has also been implicated as a cause of autism. Three other serious adverse reactions to the flu vaccine are joint inflammation and arthritis, anaphylactic shock (and other life-threatening allergic reactions), and Guillain-Barré syndrome, a paralytic autoimmune disease.

One credible hypothesis that explains the seasonal nature of flu is that influenza is a vitamin D deficiency disease. Vitamin D levels in your blood fall to their lowest point during flu seasons. Unable to be protected by the body’s own antibiotics (antimicrobial peptides) that are released by vitamin D, a person with a low vitamin D blood level is more vulnerable to contracting colds, influenza, and other respiratory infections.

Studies show that children with rickets, a vitamin D-deficient skeletal disorder, suffer from frequent respiratory infections, and children exposed to sunlight are less likely to get a cold. The increased number of deaths that occur in winter, largely from pneumonia and cardiovascular diseases, are most likely due to vitamin D deficiency.

In a pre-program assessment where patients reported an average of just under one hour of exercise per week, individuals who were more active reported better overall-quality of life. They also reported improvements in their ability to perform daily tasks.

Quality of life improvements associated with higher activity levels included the ability to complete basic daily tasks such as getting up from chairs, using the stairs, dressing and undressing, and improvements to physical symptoms like shortness of breath.

Dr. Moulden says the shots cause your body's immune systems to hyper-react as large white blood cells naturally rush to attack the foreign particles injected into your bloodstream. The white blood cells are too big to enter, so they surround tiny capillaries where the foreign particles land, and then clog and collapse the capillaries.

When the particles float near the brain, this lack of blood supply can lead to autism, SIDS and many other diagnosed illnesses in both children and adults.

1. How to Make People Like You and Network

For a skill that affects every area of your life (from dating, to family, to work), it’s amazing how little people know about this.

The report says that between 2000 and 2007, median earnings in Nevada rose 21.4 percent, from $25,411 to $30,859. During the same period, health care premiums for families rose by 54.6 percent, from $6,688 to $10,341.

The report also says that while Nevadans are paying more for health care, the amount of coverage is decreasing.

Eating too much activates a normally dormant immune system pathway in your brain, which sends out immune cells to attack and destroy invaders that are not there. This finding could help explain why obesity causes so many different diseases.

Studies that have shown that obesity causes chronic inflammation throughout the body. This inflammation is found in a range of diseases related to obesity, including heart disease and diabetes.
