Resting metabolic rate (RMR)

Resting  metabolic  rate  (RMR) is the rate at which a person burns calories while at rest. Between 70 and 80% of all calories are burned under resting conditions. Knowledge of metabolic rate is vital to nutritional assessment, weight loss planning and care of various medical conditions.

The primary method of metabolic rate measurement is indirect calorimetry. In indirect calorimetry, the rate at which oxygen is consumed and carbon dioxide is produced are measured directly and the caloric burn rate is calculated from the measured oxygen consumption and CO2 production. The relationship between oxygen consumed and calories burned is defined by the Wier equation. The standard Wier equation defines the relationship between oxygen consumption (VO2), CO2 production and energy expenditure. Weir also showed that for a specific measurement technique, energy expenditure (caloric burn rate) could be measured without requiring carbon dioxide production measurements.  The standard metabolic rate measurement instruments such like MedGem, BodyGem, Futrex are available on the internet and worth try.

The test system (ReeVue, Korr Medical Technologies, Salt Lake City, UT) is less complex and much less expensive than the standard metabolic rate measurement instruments. Traditionally, metabolic measurements are large instruments that require frequent calibration of their oxygen and CO2 sensors. This type of system is often referred to as a “metabolic cart” because the size of the instrument and related computer and calibration equipment required a cart for transport within the hospital. We compared the REEVUE system against the Deltatrac metabolic cart (Datex-Ohmeda, Finland). The Deltatrac system represents an established clinical standard that has been validated clinically and in-vitro.

Autism’s facts

7 facts of which continue to resonate today:

-some clearly autistic children are born to parents who do not fit the autistic parent personality pattern;

-parents who do fit the description of the supposedly pathogenic parent almost invariably have normal, non-autistic children;

-with very few exceptions, the siblings of autistic children are normal;

-there is a consistent ratio of three or four boys to one girl; virtually all cases of twins reported in the literature have been identical, with both twins afflicted;

-autism can occur or be closely simulated in children with known organic brain damage;

-and the symptoms are unique and specific. The two pieces of evidence he originally proposed and subsequently moved away from are that autistic children’s behavioral differences can be observed from the moment of birth, and that there is an absence of gradations of infantile autism, which would create “blends” from normal to severely afflicted. Yet, today, quite the opposite of this latter point is considered true of autism:

-it is a claim commonly found in the literature, and made by my participants, that there are so many individual differences in people with autism, that it is difficult to make generalizations beyond the “core deficits” of social, emotional, and communicative difficulties

autistic children need physical exercises since they are special in many aspects such as discipline. Power 90 Master Series or insanity workout is one of interesting conclusion for this. P90X is a training tool that helps a lot of people in gaining body health.

Is Autism Iatrogenic?

That is, what do we do while we wait for all the hundreds of studies that need to be done to see if the vitamin D theory is correct? The studies will take years. If we do nothing but just wait, we are continuing an unplanned naturalistic experiment on pregnant women, the brains of their unborn children, and upon autistic individuals. A risk/benefit analysis tells us the risk of doing nothing is potentially great while the risk of treating vitamin D deficiency is minimal, simply good medicine, and the better choice.

So until we know for sure, pregnant women, infants, children, everyone—especially autistic children—should receive sensible sun exposure daily: around noon or 1:00 p.m., expose as much skin as possible, 10–30 minutes duration, depending on how easily one sunburns. In the winter, use a suntan parlor once a week, with the same precautions—or better yet, purchase an ultraviolet vitamin D lamp for home use.

I Prefer to avoid sunlight, what should I do?

You and your child should have a vitamin D blood test, called a 25-hydroxyvitamin D . Then take enough vitamin D to achieve adequate (natural summertime) levels. Given what we do know, adequate 25(OH)D levels are now thought to be somewhere above 40 ng/mL (100 nmol/L) and probably closer 50 ng/mL (125 nmol/L). Ideal levels are unknown but they are probably close to levels that were present when the human genome evolved. Natural levels (levels found in humans who live or work in the sun) are around 50–80 ng/mL (125–175 nmol/L). These levels are obtained by only a small fraction of modern humans.

How much vitamin D should I take?

The Food and Nutrition Board set the current Upper Limit for medically-unsupervised intake by infants and babies (up to the age of 1 years-old) at 1,000 units/day. This means the government says it is safe to give infants and babies up to 1,000 units a day without getting a blood test. Of course, with correct sun exposure in the summer this is not necessary, but it will be in winter. Children over 1 years of age, according to the Food and Nutrition Board, may safely take 2,000 units/day—again, without requiring a blood test.

For adolescents, pregnant women, and other adults, the government’s Upper Limits are a problem. While a 2,000-unit Upper Limit is entirely appropriate for younger children, such limits in heavier adolescents, adults, and pregnant women limit effective treatment of vitamin D deficiency. However, these limits no more impair a physician’s ability to treat vitamin D deficiency with higher doses than comparable Upper Limits for calcium or magnesium impair their ability to treat calcium or magnesium deficiencies with higher doses, should those deficiencies be diagnosed.

In the absence of sun exposure and in winter, heavier children, adults, and pregnant women may require doses above 2,000 units daily (depending on pre-existing blood levels, body weight, degree of skin pigmentation, age, and latitude of residence) in order to obtain and maintain levels of 50–80 ng/mL. For example, Professor Heaney at Creighton University has estimated that about 3,000 units/day is required simply to assure that 97% of adult Americans obtain levels greater than 35 ng/mL. Healthy adult men utilize up to 5,000 units of vitamin D per day, if present in the body. Professors Bruce Hollis and Carol Wagner, in South Carolina, have been giving pregnant women 4,000 units/day for years. Professor Vieth, at the University of Toronto, found that actual vitamin D toxicity, with systemic symptoms, is exceedingly rare and requires much higher doses than those discussed above. When exceeding the Upper Limit, periodic serum 25(OH)D and calcium levels will reassure both physician and patient that such amounts are safe as well as convince all concerned that the government should revise their 10-year-old (yet most current) recommendations—the sooner the better.

Is Autism Iatrogenic

If the vitamin D theory of autism is correct, then to the extent it is correct, the current plague of autism is an iatrogenic disease, caused by modern sun-avoidance and the organizations that promulgated it. Long before we worshipped our current gods, primitive humans venerated an older god, the sun. Much as we have shunned our modern gods, 20 years ago we shunned the sun, hiding from it under buildings, cars, shade, and sunblock. We told the sun she was damaging us, and banished her from our lives—and from the lives of our pregnant women and our children. Tragically, we relied on medical knowledge instead of human traditions, government recommendations instead of common sense, the latest science instead of basic instincts. The ancient Greeks, who loved the sun, knew the gods seldom reward such hubris. Money saving for children healthy with payday advance

6 Top Vaccine Myths

Hours after a baby is born, her parents are told it’s best that she receive her first shot before she leaves the hospital. And that’s just the beginning. By the child’s sixth birthday, she’ll have had at least 35 vaccinations—if she goes by government recommendations. Meanwhile, during those six years, her parents are likely to see hundreds of media reports and online message-board debates about which vaccines are necessary or even safe. It’s confusing, to say the least.

To sort through the onslaught of information and misinformation about childhood immunizations, we asked Austin, Texas-based pediatrician Ari Brown, coauthor of “Baby 411: Clear Answers and Smart Advice for your Baby’s First Year,” to debunk some of the most common vaccination myths.

Myth 1: It’s not necessary to vaccinate kids against diseases that have been largely eradicated in the United States.
Reality: Although some diseases like polio and diphtheria aren’t often seen in America (in large part because of the success of the vaccination efforts), they can be quite common in other parts of the world. The Centers for Disease Control and Prevention warns that travelers can unknowingly bring these diseases into the United States, and if we were not protected by vaccinations, these diseases could quickly spread throughout the population. At the same time, the relatively few cases currently in the U.S. could very quickly become tens or hundreds of thousands of cases without the protection we get from vaccines. Brown warns that these diseases haven’t disappeared, “they are merely smoldering under the surface.”

Most parents do follow government recommendations: U.S. national immunization rates are high, ranging from 85 percent to 93 percent, depending on the vaccine, according to the CDC. But according to a 2006 study in the Journal of the American Medical Association, the 20 states that allow personal-belief opt outs in addition to religious exemptions saw exemptions grow by 61 percent, to 2.54 percent between 1991 and 2004.

Brown is concerned that parents who opt out or stagger the vaccine schedule can end up having to deal with confusing follow-up care, which could produce an increase in disease outbreaks like last summer’s measles epidemic. A 2008 study in the American Journal of Epidemiology reported that when there are more exemptions, children are at an increased risk of contracting and transmitting vaccine-preventable diseases.

Myth 2: Mercury is still in kids’ vaccines.
Reality:
At the center of this issue is a preservative called thimerosal compound containing mercury) that once was a common component in many vaccines because it allowed manufacturers to make drugs more cheaply and in multidose formulations. But public concern, new innovations and FDA recommendations led to its removal from almost all children’s vaccines manufactured after 2001. Since flu vaccines are not just for children, manufacturers still put thimerosal in some flu-shot formulations. You can ask your pediatrician for the thimerosal-free version, says Brown.

If your child does not have asthma and is at least 2 years old, Brown recommends the FluMist nasal-spray vaccination over the flu shot. “It seems to have better immune protection and it could help your child avoid another shot,” she says. (Caveat: the spray does contain a live version of the virus, which can result in a slight increase in flulike symptoms).

Myth 3: Childhood vaccines cause autism.
Reality:
There is no scientific evidence that this link exists. Groups of experts, including the American Academy of Pediatrics and the Institute of Medicine (IOM), agree that vaccines are not responsible for the growing number of children now recognized to have autism.

Earlier this month, the law supported scientists’ conclusions in this arena with three rulings from a section of the U.S. Court of Federal Claims, which stated that vaccines were not the likely cause of autism in three unrelated children. The U.S. Department of Health and Human Services said in an online statement following the ruling, “The medical and scientific communities have carefully and thoroughly reviewed the evidence concerning the vaccine-autism theory and have found no association between vaccines and autism.” Noting the volume of scientific evidence disproving this link, an executive member of one of the nation’s foremost autism advocacy groups, Autism Speaks, recently stepped down from her position because she disagrees with the group’s continued position that there is a connection between the vaccines and autism.

Myth 4: Getting too many vaccines can overwhelm the immune system and cause adverse reactions or even serious illness.
Reality:
Children’s immune systems are capable of combating far more antigens (weak or killed viruses) than they encounter via immunizations. In fact, the jury is still out on if there’s an actual limit on how many the body can handle—though one study puts the number around a theoretical 10,000 vaccines in one day.(Visit the American Academy of Pediatrics’ site or the Network for Immunization Information for more information)

Currently, “There is even less of a burden on the immune system [via vaccines] today than 40 years ago,” says Edgar Marcuse, a professor of pediatrics at the University of Washington who works on immunization policy and vaccines. He points to the whooping-cough vaccine as an example where there are far fewer antigens in the shot than the earlier version administered decades ago. Brown says she supports following the recommended schedule for vaccinations, which outlines getting as many as five shots in one day at a couple check-ups.

The CDC reports that most vaccine adverse events are minor and temporary, such as a sore arm or mild fever and “so few deaths can plausibly be attributed to vaccines that it is hard to assess the risk statistically.” Of all deaths reported to the Health and Human Services’ Vaccine Adverse Events Reporting site between 1990 and 1992, only one is believed to be even possibly associated with a vaccine. The Vaccine Safety Datalink Project, an initiative of the CDC and eight health-care organizations, looks for patterns in these reports and determines if a vaccine is causing a side effect or if symptoms are largely coincidental.

If you have concerns about following the recommended vaccination, schedules don’t wait until a check-up. Set up a consultation appointment with your pediatrician, or even outline a strategy for care with your doctor during your pregnancy.

Myth 5: It’s better to let my kid get chickenpox “naturally.”
Reality:
Before the chickenpox vaccine was licensed in 1995, parents sometimes brought their child to a party or playground hoping that their child might brush up against a pox-laden kid to get their dose of chickenpox over since cases were usually less severe for children than adults. But pediatricians say severe complications are possible with chickenpox—including bacterial infections that could result in a child’s hospitalization or death.

Now that there’s a vaccine for chickenpox, more than 45 states require the shots (unless your child already had the chicken pox or can prove natural immunity). Two shots usually guarantees your child a way out of being bedecked in calamine lotion for two feverish weeks, but some individuals do still come down with a milder form of the pox. Most pediatricians recommend getting the shot.

Myth 6: The flu shot causes the flu.
Reality:
The flu shot does not contain a live virus, so your child can’t get the flu from this shot. But, after the shot, it’s not uncommon to feel a bit achy while the immune system mounts its response. Remember that for two weeks following the shot, your child can still get the flu, so be sure to help your child avoid that feverish kid next door.
