New Chemical Is Said to Provide Early Sign of Alzheimer’s Disease

A chemical designed by doctors in Los Angeles could give earlier signals of Alzheimer’s disease and provide a new way to test treatments, a study has shown.

Currently, the only way to diagnose the disease is to remove brain tissue or to perform an autopsy.

The new study, to be published today in the New England Journal of Medicine, is by doctors at the University of California, Los Angeles, and is part of a larger quest to find a better method to diagnose the condition using tracers that can be detected with a positron emission tomography, or PET, scan.

The new chemical, called FDDNP, attaches to abnormal clumps of proteins called amyloid plaques and nerve cell tangles that develop in Alzheimer’s sufferers and inhibit messages being processed by the brain.

In the study, Dr. Gary Small and his colleagues discovered that the chemical allowed doctors to pick out which of 83 volunteers had Alzheimer’s, which had mild memory problems and which were functioning normally for their age.

It was 98 percent accurate in determining the difference between Alzheimer’s and mild cognitive impairment, which surpassed the 87 percent success rate for a PET scan test that measured sugar metabolism in the brain, and the 62 percent accuracy rate when doctors used a magnetic resonance imaging.

The FDDNP signal can be seen in people years before they develop Alzheimer’s disease, Dr. Small said.

Finding an easier way to track brain deterioration would also make it easier to assess experimental treatments, as researchers try to prevent or reduce the accumulation of plaques and tangles.

Dr. Small and 4 of the other 15 authors named in the research paper have a financial interest in FDDNP, which has been licensed to the German conglomerate Siemens AG. He said he hoped to see it on the market in three years.

About 4.5 million people in the United States have Alzheimer’s, a number that is expected to grow as the population ages. About 15 million to 20 million more have the mild cognitive impairment that often leads to the disease.

Selenium

[amazon_link asins=’B00SJKPBNY,B000H85L5Y,B000F4ZVKK,B004R65LWA,B009EA6FZG,B00B5N9IDQ,B000G24ZW6,B00M13NHFY,B01N5FHG46′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’a5b0680f-abf8-11e7-b687-79d16c5dac5a’]

What is selenium?…..click & see
An essential trace element, selenium is nonmetallic, gray in appearance, and similar to sulfur in its chemical composition. It is often available in single or multivitamin supplements.

Why do we need it?
Selenium is needed to activate a number of hormones produced by the thyroid gland. It also activates an antioxidant enzyme called glutathione peroxidase, which may help protect the body from cancer, and has been shown to induce “apoptosis” (programmed cell death) in cancer cells. Selenium also plays a vital role in the functioning of the immune system. Studies have found that selenium supplementation stimulates the activity of white blood cells. It also enhances the effect of vitamin E, one of three vitamins that act as antioxidants.

How much selenium should I take?
According to the National Academy of Sciences, the recommended daily allowance (RDA) of selenium is as follows:

Adult men: 55 micrograms/day
Adult women: 55 micrograms/day
Children aged 7-10: 30 micrograms/day
Infants: between 10-15 micrograms/day
Pregnant/lactating women: between 65-75 micrograms/day


What are some good sources of selenium?

Brazil nuts are the best source of selenium. Yeast, whole grains, garlic and seafood are also good sources. Some vegetables may contain considerable amounts of selenium depending on the content of selenium in the soil.

What can happen if I don’t get enough selenium?
While most people do not consume enough selenium on a daily basis, severe deficiency is rare. Soils in some areas are selenium deficient, and people who eat foods grown primarily on selenium-poor soils can be at greater risk for deficiency. The most notable condition caused by selenium deficiency is Keshan disease, which causes an abnormality of the heart muscle. Some studies have shown that patients with AIDS have abnormally low levels of selenium. Other research has demonstrated an association between heart disease and depleted levels of selenium.

What can happen if I take too much?
Taking large amounts (more than 1,000 micrograms) of selenium per day can cause the loss of fingernails, teeth, and hair; nausea; and fatigue. In conjunction with iodine-deficiency induced goiter, selenium supplementation has been reported to increase the severity of low thyroid function.

Earache (Ear Infection)

Whether it’s a middle ear infection, located deep in the ear, or swimmer’s ear, affecting the outer ear canal, an earache hurts. It’s most often a problem in children, but adults get earaches too. Though some conditions clear up on their own, supplements can speed up the healing process….click & see

Symptoms:

Throbbing or steady pain in ear; pain when pulling on lobe.
Pressure or itching in the ear.
A bloody, green, yellow, or clear discharge from the ear.
Muffled hearing; popping in ear.
Fever.
Dizziness.

When to Call Your Doctor
If earache is accompanied by fever over 101 F, stiff neck, severe headache, or seepage of pus or other fluids; or if the ear or area behind it appears red or swollen — it is likely an infection requiring antibiotics.

What It Is
An earache results from inflammation, infection, or swelling in the outer canal of the ear or in the space adjoining the eardrum, which is the thin membrane that separates the outer and the middle ear. Normally, the eustachian tube, which extends from the middle ear to the throat, drains fluids from the ear, keeping it clear. But inflammation or infection can irritate the ear canal or block the Eustachian tube, leading to the buildup of pus or other fluids and causing pain and other unpleasant symptoms.


What Causes It

Earaches are typically caused by harmful bacteria, viruses, or fungi, usually preceded by an upper respiratory infection or seasonal allergies, or moisture trapped in the ear. Other causes include excessive ear wax, sudden changes in air pressure, a punctured eardrum, or exposure to irritating chemicals, such as hair dyes and chlorinated water.

How Supplements Can Help
The supplements listed below can play a supportive role in healing earaches. They can be used in conjunction with antibiotics, pain relievers, and other conventional remedies for short-term treatment of mild to moderate ear discomfort. All severe, lingering, or recurrent ear pain, however, requires medical evaluation.

What Else You Can Do
Place a warm compress on the outside of your ear; use a heating pad or warm washcloth. Heat can bring quick pain relief and facilitate healing.
Never insert a cotton swab, which can puncture the eardrum, into your ear. Don’t use hydrogen peroxide as a cleaner; it can irritate the ear canal.
Herbal eardrops often bring rapid pain relief — within 10 minutes of administration. To make the application of drops more comfortable, warm the bottle under hot running tap water before placing the liquid in the ear.
Don’t smoke and avoid smoke-filled rooms, especially if you’re prone to earaches. The latest study to look at the link between secondhand smoke and ear infections reported that exposure to smoke can affect the ears. Children who lived in households with at least two smokers were 85% more likely to suffer from middle ear infections than those who lived in nonsmoking homes.

Fish Oil Linked to Lower Alzheimer’s Risk

A substance found in fish oil may be associated with a significantly reduced risk of developing Alzheimer’s and other dementias, researchers reported yesterday…….click & see

The scientists found that people with the highest blood levels of an omega-3 fatty acid called docosahexaenoic acid, or DHA, were about half as likely to develop dementia as those with lower levels.

The substance is one of several omega-3 polyunsaturated fatty acids found in fatty fish and, in small amounts, in some meats. It is also sold in fish oil or DHA supplements. The researchers looked for a reduced risk associated with seven other omega-3 fatty acids, but only DHA had any effect.

The study, in the November’06 issue of The Archives of Neurology, used data from the Framingham Heart Study to follow 899 initially healthy participants, with a median age of 76, for an average of more than nine years.

The scientists assessed DHA and fish intake using a questionnaire and obtained complete dietary data on more than half the subjects. They took blood samples from all the participants to determine serum levels of fatty acids.

Ninety-nine people developed dementia over the course of the study, including 71 cases of Alzheimer’s disease. The average level of DHA among all the participants was 3.6 percent of all fatty acids, and the top 25 percent of the population had values above 4.2 percent. People in this top one-quarter in DHA levels had a 47 percent reduced risk of developing dementia, even after controlling for body mass index, diabetes, hypertension, smoking status and other known or suspected risks. Risk reduction was apparent only at that top level of DHA — those in the bottom three-quarters in DHA level showed no detectable difference in risk.

People who ate two or more servings of fish a week reduced their risk for dementia by 39 percent, but there was no effect on the risk for dementia among those who ate less than that.

The finding that DHA alone reduces risk, the authors write, is consistent with earlier data showing high levels of DHA in healthy brain tissue and low levels in the brains of people with Alzheimer’s disease.

Dr. Ernst J. Schaefer, the lead author of the study, was cautious in interpreting the results.

“This study doesn’t prove that eating fish oil prevents dementia,” he said. “It’s an observational study that presents an identified risk factor, and the next step is a randomized placebo-controlled study in people who do not yet have dementia.” Dr. Schaefer is chief of the Lipid Metabolism Laboratory at Tufts University.
The study was financed in part by Martek, a concern that manufactures DHA, and one author received a grant from Pfizer, France.

Eating fish is not a guarantee of having high levels of DHA. In fact, fish intake accounted for less than half of the variability in DHA levels. Other dietary intake and genetic propensities probably account for the rest. Dr. Schaefer pointed out that the kind of fish consumed is important. Fatty fish, he said, is best, and frying will cause DHA to deteriorate.

Supplements may be an additional source of DHA, but an editorial in the same issue, by Dr. Martha Clare Morris, an associate professor of medicine at Rush University Medical Center in Chicago, points out that there are no published human studies of the effects of omega-3 fatty acid supplementation. The Food and Drug Administration does not endorse DHA or fish oil capsules, but recognizes doses of up to 3 grams a day of fish oil as generally safe. High intakes of fish oil can cause excessive bleeding in some people.

Dr. Morris writes that there are few human studies examining the effect of mercury intake from eating seafood, and it is not known if the risks of eating fish outweigh the benefits.

But, she adds, epidemiological studies consistently show positive health effects from fish consumption on mortality, cardiovascular risk factors and, now, dementia.

Alcohol Can Trigger Heartburn

[amazon_link asins=’B00BV47KTS,0679767959,B0019J6XSY,B0023UZOFQ,B0000X02TQ,B00I8MI3MO,B074SLRQLV,0976642530,B001CZ7G1I’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’5da76944-1148-11e8-8ee5-1921a005b9be’]

Alcohol can have several unpleasant affects on heartburn sufferers, so it is best to avoid alcohol if you suffer from acid reflux. There are a few tips that may make it possible for you to enjoy alcoholic beverages — if consumed in moderation……...CLICK & SEE

Why Alcohol Makes Heartburn Worse
Alcohol consumption should be reduced or avoided because:

* Alcohol increases the production of stomach acid.
* Alcohol relaxes the lower esophageal sphincter (LES), allowing stomach contents to reflux back up into the esophagus.
* When the LES relaxes, it causes swallowing contractions to become erratic.
* Alcohol makes the esophagus more sensitive to stomach acid.
* Alcohol can lead to the development of peptic ulcers and interfere with the healing of ulcers already present.

If You’d Still Like the Occasional Alcoholic Beverage
To minimize alcohol’s affect on your digestive system:

* Dilute alcoholic beverages with water or club soda.
* Drink moderate amounts of alcoholic beverages — the suggested amounts are 1 to 2 mixed drinks, 12 to 16 ounces of wine, or 2 to 3 beers.
* When having wine, drink white wine instead of red.
* Choose non-alcoholic beer or wine.
* Keep track of which alcoholic drinks aggravate your heartburn, and avoid them as much as possible.
