What Works Against Alzheimer’s?

.Eli Lilly’s promising drug solanezumab failed; so, what works against Alzheimer’s? This drug was supposed to dissolve the amyloid deposits that function like glue and make the patients lose their memory. This phase 3 trial was to test the drug on patients to assess efficacy, effectiveness and safety. But instead it showed that the new drug did not stop the loss of memory.

Brain bleeding as a side effect of potential Alzheimer’s drug

Now all those who were hoping for solanezumab to be effective, will jump on another drug, aducanumab. Biogen from Cambridge, Massachusetts, has developed this drug. Out of 165 subjects only 125 completed preliminary studies. 40 patients who discontinued it, had negative side effects. These included fluid building up in the brain, which was thought to be due to removal of the plaques. But others, had brain bleeding.

Although the drug manufacturer is still hoping that aducanumab will work out as an anti-Alzheimer’s drug, I have my doubts. A drug that can have potential brain bleeding as a side effect does in my opinion not qualify as an anti-Alzheimer’s drug.

Factors that help prevent Alzheimer’s

1. Diet can be as effective as a drug in treating Alzheimer’s

In September 2015 researchers from Rush University published results of putting Alzheimer’s patients on the MIND diet. The MIND diet was a prospective study where 923 people aged 58 to 98 years participated. Researchers followed these people for 4.5 years. Three groups of diets were tested: Mediterranean diet, DASH diet and MIND diet.

The MIND diet study result

The adherence to the diet was measured: those who followed the diet very closely, other participants who were less diligent, and finally those who were not compliant with the diet. With regard to the MIND diet the group with the highest adherence to the diet reduced the rate of Alzheimer’s by 53% compared to the lowest third. This is like a highly effective Alzheimer’s drug! The second group still was able to reduce the rate of Alzheimer’s by 35%, which would be like a regular strength drug. The control diets were the DASH diet and the Mediterranean diet. The group that was strictly adhering to the DASH diet reduced Alzheimer’s by 39%, the group that was very conscientious in adhering to the Mediterranean diet reduced Alzheimer’s by 54%. The middle thirds of both control diets did not show any difference versus the lower thirds.

Findings of Alzheimer prevention by diet

The conclusion was that a strict Mediterranean diet had a very good Alzheimer prevention effect, as did a strict MIND diet. However, when patients did not adhere too well to a diet, the MIND diet was superior still yielding 35% of Alzheimer’s prevention after 4.5 years. The other diets, when not adhered to that well, showed no difference from being on a regular North American diet. Here is more info about the MIND diet.

Conclusion

Avoid the Standard American Diet. Adopt a Mediterranean diet and stick to it in a strict fashion or adopt the MIND diet. The other benefit is that there are no side effects!

2. Stress and Alzheimer’s

2010 study from Gothenburg University, Sweden examined 1462 women aged 38-60 and followed them for 35 years.

Psychological stress ratings went back to 1968,1974 and 1980. 161 females developed dementia (105 of them Alzheimer’s disease, 40 vascular dementia and 16 other forms of dementia). The risk of dementia was higher in those women who had frequent/constant stress in the past. The condition became more severe the more stress they had to face in the past. Women with exposure to stress on one, two or three examinations had higher dementia rates later in life in comparison to women who had no exposure to any significant stress. Specifically, dementia rates were 10% higher after exposure to one stressful episode, 73% higher after two stressful episodes and 151% higher after exposure to three stressful episodes.

Conclusion

Prevention of Alzheimer’s is possible by avoiding stress and seeking counselling when stress occurred .

3. Be creative, prevent Alzheimer’s and dementia

In an April 8, 2015 publication from the Mayo Clinic in Rochester, MN and Scottsdale, AZ 256 participants aged 85 years and older (median age 87.3 years, 62% women and 38% men) were followed for 4.1 years. Psychological tests measured mild cognitive impairment (MCI). At the time of recruitment into the study all of the tests for MCI were normal. As the study progressed it became apparent that there were various risk factors that caused the onset of MCI, which is the immediate precursor of dementia/Alzheimer’s disease.

The finding was that the presence of the genetic marker APOE ε4 allele carried a risk of 1.89-fold to develop MCI and later Alzheimer’s disease.

Further findings of the study

When patient showed signs of depression at the time of enrolment into the study, the risk of MCI development was 1.78-fold. Midlife onset of high blood pressure led to a 2.43-fold increase and a history of vascular disease showed a relationship of 1.13-fold higher MCI development. The good news was that four activities correlated with a lower risk of developing MCI with aging. When the person engaged in artistic activities in midlife or later in life the risk for MCI development 73% lower, involvement in crafts reduced it by 45% and engagement in social activities by 55%. In a surprise finding the use of a computer late in life reduced MCI development by 53%. These are very significant observations. This would be equivalent to highly effective anti-Alzheimer’s drugs.

Conclusion

If you stimulate your mind in older age, even browsing on the computer, this will help you to prevent Alzheimer’s disease.

4. Lifestyle factors contributing to Alzheimer’s

a) Sugar consumption: Sugar consumption and too much starchy food like pasta (which gets metabolized within 30 minutes into sugar) causes oxidization of LDL cholesterol and plaque formation of all the blood vessels including the ones going to the brain. On the long-term this causes memory loss due to a lack of nutrients and oxygen flowing into the brain.

b) Lack of exercise: Lack of exercise is an independent risk factor for the development of Alzheimer’s disease. Exercise increases the blood supply of the brain, strengthens neural connections and leads to growth of neurons, the basic building blocks of the brain. Exercise increases mood-regulating neurotransmitters like serotonin and endorphins.

c) Sleep deprivation leads to memory loss, but so does the use of aspartame, the artificial sweetener of diet sodas. Make your own homemade lemonade. Squeeze the juice of half a lemon. Add mineral water to fill an 8 oz. glass. Add a tiny bit of stevia extract for sweetening. Stir and enjoy. Stevia has been in use for thousands of years.

5. Hormone changes

A lack of testosterone in men and estrogen in women interferes with cognition and memory. For this reason it is important after menopause and andropause (=the male menopause) to replace what is missing with the help of a knowledgeable health professional.

Progesterone is manufactured inside the brain, spinal cord and nerves from its precursor, pregnenolone, but in women it also comes from the ovaries until the point of menopause. The myelin sheaths of nerves requires progesterone and progesterone also has a neuroprotective function. In menopausal women bioidentical progesterone is a part of Alzheimer’s prevention.

Melatonin is a hormone, a powerful antioxidant and a neurotransmitter at the same time. It helps in the initiation of sleep, stimulates the immune system and protects from the toxic effects of cobalt. Lab tests in Alzheimer’s patients found elevated values. In an aging person it is wise to use melatonin at bedtime as a sleep aid and to preserve your brain.

6. Genetic risk of Alzheimer’s

At the 22nd Annual A4M Las Vegas Conference in mid December 2014 Dr. Pamela Smith gave a presentation entitled ”How To Maintain Memory At Any Age”. She pointed out that there are about 5 genes that have been detected that are associated with Alzheimer’s disease and in addition the apolipoprotein E4 (APOE4). About 30% of people carry this gene, yet only about 10% get Alzheimer’s disease, which shows how important lifestyle factors are (in medical circles physicians call this the “epigenetic factors”) to suppress the effect of the APOE4 gene. She also stated that our genes contribute only about 20% to the overall risk of developing Alzheimer’s disease. This leaves us with 80% of Alzheimer’s cases where we can use the brain nutrients and hormones discussed above and exercise to improve brain function.

7. Vitamin D3 protects your brain from Alzheimer’s disease

Alzheimer’s disease is a neurodegenerative disease of old age. We know that it is much more common in patients with type 2 diabetes where insulin levels are high. Studies have shown that Alzheimer’s disease can be termed type 3 diabetes.

The resulting neurofibrillary tangles and amyloid-beta deposits damage nerve cells, which are responsible for the memory loss and the profound personality changes in these patients.

What does vitamin D3 have to do with this?

A 2014 study showed that a low vitamin D level was associated with a high risk of dementia and Alzheimer’s disease.

Specifically, the findings were as follows.

  • Vitamin D level of less than 10 ng/ml: 122% increased risk of Alzheimer’s
  • Vitamin D level 10 to 20 ng/ml: 51% increased risk of Alzheimer’s

The same research group found in two trials that vitamin D deficiency leads to visual memory decline, but not to verbal memory decline.

Generally supplements of vitamin D3 of 5000 IU to 8000 IU are the norm now. But some patients are poor absorbers and they may require 15,000 IU per day. The physician can easily determine what the patient needs in the dosage of vitamin D3 by doing repeat vitamin D blood levels (as 25-hydroxy vitamin D levels). The goal is to reach a level of 50-80 ng/ml. The optimal level with regard to nmol/L is 80 to 200 (according to Rocky Mountain Analytical, Calgary, AB, Canada).

8. Avoid sugar overload

We already mentioned sugar consumption under point 4. But here I am mentioning it again because of the insulin reaction. An overload of refined carbs leads to an overstimulation of the pancreas pouring out insulin. Too much insulin (hyperinsulinemia) causes hormonal disbalance and leads to diabetes type 3, the more modern name for Alzheimer’s. All starch is broken down by amylase into sugar, which means that anybody who consumes starchy food gets a sugar rush as well. Too much sugar in the blood oxidizes LDL cholesterol, which leads to inflammation in the body. The consequence of chronic inflammation are the following conditions: hardening of the arteries, strokes, heart attacks, Alzheimer’s due to brain atrophy, arthritis, Parkinson’s disease and cancer.

What Works Against Alzheimer’s?

What Works Against Alzheimer’s?

Conclusion

In the beginning we learnt about a failed phase 3 trial regarding an anti-Alzheimer’s drug. Next we reviewed several factors that can all lead to Alzheimer’s and that have been researched for many years. It would be foolish to think that we could just swallow a pill and overlook the real causes of Alzheimer’s disease. I believe there will never be a successful pill that can solve the increasing Alzheimer’s problem. It is time that we face the causes of Alzheimer’s. This means cutting down sugar to normalize your insulin levels.

Lifestyle changes necessary to avoid Alzheimer’s

We need to supplement with vitamin D3 because we know that it helps. For women in menopause or men in andropause it is time to replace the missing hormones with bioidentical ones. We need to handle stress and avoid sleep deprivation. And, yes we need to exercise regularly. Following a sensible diet like the Mediterranean diet or the MIND diet makes sense. And let us keep our minds stimulated. Chances are, when we do all of this that we will not need any Alzheimer’s pill. This is not good news for the drug companies, but will be very good news for you. Last but not least, there are no side effects, only health benefits!

Spironolactone Helps Against Herpes Infections

There are limited numbers of antiviral drugs for herpes, but certainly now research showed that spironolactone helps against herpes infections. Spironolactone is an older heart medicine that helps with cardiac failure, but it is also used in unwanted hair growth in women with a hormone disbalance, called hirsutism.

Dr. Swaminathan and colleagues have shown in new research from the University of Utah School of Medicine, Salt Lake City, UT that spironolactone blocks the multiplication of herpes viruses.

Common herpesvirus infections

Although there are 100’s of different herpes virus strains, you will recognize some of the following names.

Herpes, type 1 (HSV-1)

HSV-1 causes cold sores on the lips or inside the mouth.

Herpes, type 2 (HSV-2)

HSV-2 is the cause of genital herpes.

Herpes, type 3 (HSV-3)

HSV-3 causes both chickenpox and shingles (herpes zoster). When the immune system is immature, it presents as chickenpox (mostly in children). But when there is partial immunity from a chickenpox childhood infection, shingles can present in an aging person as a localized shingle infection (medically called “herpes zoster”). An interesting vaccination study showed that vaccination against varicella caused a suppression of chronic HSV-1 so that there were no more cold sores compared to the non-vaccinated group that did.

Herpes, type 4 (HSV-4)

You may know HSV-4 as the Epstein-Barr virus. It is the cause of infectious mononucleosis. Other names for this disease are glandular fever or “kissing disease”.

Treatments for herpes infections

The typical antiviral treatments for HSV-1 and HSV-2 are acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex). As a matter of fact, all these drugs belong to the same pharmacological class of drugs. The same drugs work for chickenpox and shingles/herpes zoster (HSV-3).

In a 2013 publication researchers gave acyclovir (Zovirax) to patients who had been hospitalized with infectious mononucleosis.

They had a shorter duration of hospitalization and fever than a control group not treated with acyclovir. The authors did propose that patients with mononucleosis should receive acyclovir.

Drug-resistant herpes strains

One problem that has surfaced is that herpes drug resistant herpes strains seem to evolve, which are resistant to all of the newer anti-herpes drugs as well. The reason for this is that current anti-herpes drugs work by inhibiting the ability of the virus to replicate DNA, thus stopping its proliferation. When the virus learns to overcome that barrier we call this resistance and this will also affect all of the drugs that utilize the same mechanism of action.

The team from the University of Utah screened several drugs and came upon spironolactone, which is a standard medicine for treating heart failure. Dr. Swaminathan and his team found that spironolactone was also able to stop the viral proliferation, however the drug blocked the virus through a different mechanism. Spironolactone inhibited the action of a protein, the SM protein.

This different mechanism of treating herpes virus infections has opened a new door to further research for newer drugs. Hopefully these new drugs will only have the anti-herpes virus effect, but not the anti-heart failure effect. Dr. Swaminathan is confident that his team will be able to separate these two actions and then come up with a new group of anti-virus drugs.

Spironolactone helps against herpes infections, has few side-effects

Spironolactone has been on the market for over 50 years and has a very good low side effect profile. It is useful for people with heart failure to reduce the retained fluid that can accumulate around the heart or in the lungs. This allows the patient to breathe easier and have more energy. Spironolactone also helps with fluid accumulation in patients who have cirrhosis or have nephrotic syndrome, a kidney disease.

In a completely different set of patients spironolactone can help women who produce too much male hormone in their ovaries. This normalizes the hormones and help them lose the awkward, unwanted facial hair growth.

Some generalized side effects are: mild nausea, vomiting or diarrhea. Breast swelling or tenderness can develop. Dizziness, headache and mild drowsiness can occur. Some people develop leg cramps. Males can experience impotence and difficulties having an erection.

Spironolactone Helps Against Herpes Infections

Spironolactone Helps Against Herpes Infections

Conclusion

It is not often that an existing drug that has been well researched in the past finds a new application in a completely different area than originally developed for. This is the case for spironolactone, which is effective as an anti-herpetic drug. Further research will likely be able to separate the anti-viral effect of spironolactone from the anti-heart failure effect. Dr. Swaminathan and his team did not think that this was too difficult a problem. In the meantime physicians can use spironolactone for severe herpetic infections when the other drugs do not help. These may be cases of drug resistance.

Overall the detection of an anti-herpetic effect of spironolactone has been an important step forward. This is also true with respect to treating the whole group of herpetic diseases.

Magnesium Is Essential To Life

Magnesium is an important co-factor in many biochemical reactions, so magnesium is essential to life.

Many diverse diseases and cancers can develop from magnesium deficiency. The key is to supplement with magnesium regularly to get more than the government recommended daily allowance (RDA). The RDA for magnesium is 420 mg a day for males and 320 mg a day for females.

In the following I will review the diseases that occur without enough magnesium on board.

A lack of magnesium can cause heart disease

In this 2014 study 7216 men and women aged 55-80 with at high risk for heart attacks were followed for 4.8 years. The risk of death from a heart attack was found to be 34% lower in the high tertile magnesium group when compared to the lower magnesium tertile group.

The protective mechanism of magnesium was found to be as follows. Magnesium counteracts calcium and stabilizes heart rhythms. Magnesium helps to maintain regular heart beats and prevents irregular heart beats (arrhythmias). It also prevents the accumulation of calcium in the coronary artery walls. This in turn is known to lower the risk of heart attacks and strokes.

Another study, which was part of the Framingham Heart Study, examined calcification of the heart vessels and the aorta as a function of magnesium intake.

There were 2,695 participants in this study. For each increase of 50 mg of magnesium per day there was a 22% decrease in calcification of the coronary arteries. For the same increase of magnesium the calcification of the body’s main artery, the aorta, fell by 12%. Those with the highest magnesium intake were 58% less likely to have calcifications in their coronary arteries. At the same time they were 34% less likely to have calcifications of the aorta.

In a Korean study a group with low magnesium levels was at a 2.1-fold higher risk of developing coronary artery calcifications compared to a group with normal magnesium levels.

Low magnesium increases your stroke risk

In a 2015 study 4443 subjects, men and women aged 40-75 were followed along.

928 stroke cases developed. The researchers compared the group with the highest 30% of magnesium intake with the lowest 10% of magnesium intake. They had significantly lower blood pressure (7 mm mercury) and lower total cholesterol levels. They also had 41% less strokes than those with low magnesium intake.

In a 2015 study that lasted 24 years the authors investigated 43,000 men.

Those with the highest magnesium supplement had a 26% lower stroke risk. Those with the lowest magnesium intake served as a control.

Among women low magnesium levels were shown to cause 34% more ischemic strokes than in controls.

This study included 32,826 participants in the Nurses’ Health Study. Examiners followed them for 11 years.

It is clear from all these studies that supplementation with magnesium can prevent strokes.

Magnesium protects kidney function

This study examined 13,000 adults for 20 years to see how kidney function was dependent on magnesium levels. Those with the lowest magnesium levels had a 58% higher risk of developing chronic kidney disease. It makes sense when you consider that magnesium is necessary to keep arteries healthy, blood pressure low, and blood sugars stable. When diabetics do not control their blood sugars optimally their kidneys develop kidney disease. The term for this is diabetic nephropathy. In the presence of magnesium supplementation and a low sugar diet people are less likely to develop diabetes or kidney disease.

Magnesium helps blood sugar control

A metaanalysis showed that magnesium supplementation was able to improve blood sugar control. This occurred in both diabetics and borderline non-diabetics within 4 months of supplementing with magnesium.

An important factor in helping control blood sugar is magnesium. Here is an article as an example.

Magnesium good for bones and teeth

Magnesium is important for calcium metabolism and this is helping your bones and teeth to stay strong. The bones store half of the body’s magnesium. Another location for magnesium are in our teeth.

Low levels of magnesium lead to osteoporosis, because one of the two structural components of bone (calcium and magnesium) is missing. In addition low magnesium causes inflammatory cytokines to increase. These break down bones. The Women’s Health Initiative showed that when daily magnesium intake exceeded 422.5 mg their hip and whole-body bone mineral density was significantly greater than in those who consumed less than 206.6 mg daily.

With regard to healthy teeth magnesium is important as it prevents periodontal disease.

This study found that there was less tooth loss and there were healthier periodontal tissues in 4290 subjects between 20 and 80.

Those who took magnesium supplements had healthier teeth.

Migraine sufferers improve with magnesium

A double blind randomized study showed that magnesium supplementation can reduce migraines. The researchers in this trial used 600 mg of magnesium supplementation for 4 weeks.

This reduced migraines by 41.6% in the magnesium group compared to the non-supplemented control group.

Another study showed that both intravenous and oral magnesium are effective in reducing migraine headaches.

Intravenous magnesium showed effects on improving migraines within 15 – 45 minutes. The authors concluded that one could supplement other migraine treatments with both oral and intravenous magnesium.

Too little magnesium can cause cancer

It may surprise you to hear that magnesium can even prevent some cancers. Two cancers have been studied in detail. I will limit my discussion to these two.

Pancreatic cancer

One study found that pancreatic cancer was reduced. Researchers recruited 142,203 men and 334,999 women between 1992 and 2000 and included them in the study. After 11.3 years on average 396 men and 469 women came down with pancreatic cancer. On the male side they found that when the body mass index (BMI) was greater than 25.0 there was a 21% reduction of pancreatic cancer for every 100 mg of added magnesium per day. There were a lot of smokers on the female side, which interfered with the study as confounding factors undermined statistical validity.

In another study, the US male Health Professionals Follow-up Study was examined after 20 years of follow-up. Those with a BMI of above 25.0 on magnesium supplementation had a reduced risk of pancreatic cancer. The pancreatic cancer rate in the higher magnesium group was 33% lower than in the lower magnesium group. The higher group consumed 423 mg of magnesium daily, the lower group 281 mg per day. It is significant that in both studies it was the heavier patients who came down with pancreatic cancer. It is common knowledge that obesity is a pancreatic risk factor.

Colorectal cancer

A study done on Japanese men showed that magnesium could protect them significantly from colon cancer.

Men who consumed the highest amount of magnesium developed 52% less colon cancer over 7.9 years. Researchers compared them to the group with the lowest 20% intake of magnesium. The women in this study did not reach statistical significance.

A study from the Netherlands examined colon cancer in patients. They found that only in patients with a BMI of greater than 25.0 magnesium did have protective effects. For every 100 mg of magnesium per day increase there was a 19% reduction of colon polyps. And there was also a 12% reduction of colorectal cancer for every 100 mg increase of magnesium per day.

Magnesium plays an important role in genome stability, DNA maintenance and repair. It also prevents chronic inflammation and reduces insulin resistance, all factors contributing to cancer reduction.

Live longer with magnesium

Consider that magnesium is the fourth most common mineral in the body. Add to this that magnesium is a co-factor of more than 300 enzymes in the body. Magnesium is an important co-factor in the conversion of chemical energy from food that we ingest. Magnesium is regulating blood sugar, blood vessel health and our brain electrical activity. 50% of our stored magnesium is located in our bones, which helps the strength and integrity of them.

Because of the distribution of the enzymes to which magnesium is a co-factor, virtually every cell in the body depends on our regular intake of magnesium.

Magnesium deficiency develops in older age

Since the 1950’s soils have lost magnesium where farmers grow vegetables and raise fruit trees. We simply do not get enough magnesium from food.

But chelated magnesium is freely available in health food stores. Take 250 mg twice per day, and you will have enough.

Because our metabolism slows down, there is a critical age where magnesium deficiency becomes more obvious than when we are younger. By the age of 70 there are 80% of men and 70% of women who do not get the minimum of magnesium-required amount they should get (350 mg for men and 265 mg for women).

Proton pump inhibitors lowering magnesium levels

At this age many people are on multiple drugs. For many proton pump inhibitors (PPI) are used to suppress acid production in the stomach. PPI’s have been associated with low magnesium blood levels. This link explains that when a patient takes PPI’s the total time of taking the medication should not exceed 1 year.

Low magnesium levels accelerate the aging process on a cellular level. Low magnesium levels increase senescent cells that can no longer multiply. Some of them could cause the development of cancer. These senescent cells also can no longer contribute to the immune system. This causes more infections with an adverse outcome.

Remember to take chelated magnesium capsules or tablets 250 mg twice per day and you will be protected from low magnesium levels in your body.

Here is why we live longer with magnesium supplementation

Our blood vessels will not calcify as early; they keep elastic for longer, preventing high blood pressure. Our kidneys will function longer with magnesium, preventing end-stage kidney disease. We need our kidneys to detoxify our system! More than 300 enzymatic reactions all over our body help that we have more energy and also help to prevent cancer. When there are fewer strokes and less heart attacks this helps reduce mortality. Magnesium supplementation helps to lessen the risk for Alzheimer’s disease and also reduces insulin resistance. Researchers have shown that this prevents Alzheimer’s disease.

The bottom line is we live longer and healthier; that is the meaning of longevity.

Magnesium Is Essential To Life

Magnesium Is Essential To Life

Conclusion

Magnesium is a key essential mineral. It balances calcium in the body and participates in many enzymatic reactions in the body as a cofactor. As long as we have enough of this mineral we won’t notice anything. It is with magnesium deficiency that things go haywire. Heart disease or a stroke could affect you . You could get kidney disease. And you could even get pancreatic cancer or colorectal cancer. If this is not enough, magnesium deficiency can cause diabetes, osteoporosis and bad teeth. You may suddenly die with no obvious cause. But, if balance your your magnesium blood level by taking regular supplements, you will carry on living and eliminate a lot of health problems.

Cancer Rates Increased In Women

A recent review of cancer rates worldwide shows that cancer rates increased in women. This by itself is alarming, but based on that data the rates likely will go up by 60% in the year 2030. The main reason is the smoking discrepancy among women and men. Men as a group have been smoking more than women. But women as a group are more and more embracing smoking. All of the negative health consequences of the last 3 decades for men are just starting to show now for women as well.

The World Health Organization explains it this way: in high-income countries like Australia, Canada, the US and Western Europe women smoke at nearly the same rate as men.

But in low and middle income countries women do not smoke as much as men do. For instance in China 61% of men are smokers, but only 4.2% of women are smoking. In Argentina 34% of men are currently smokers, which compares to 23% of women who smoke in this country.

When this gap will close, likely by the year 2030 women will have a whole host of diverse cancers, heart attacks and strokes caused by the smoking habit.

Some statistics and facts

High-income countries like Australia, Brazil, Canada, Israel and many northern and western European countries have a 5-year survival rate for breast cancer of 85%. In contrast the 5-year survival rates are 60% or less in low- and middle-income countries like South Africa, Mongolia, Algeria and India.

Cancer prevention measures can make a big difference later in life. Examples are hepatitis B vaccination, which will prevent liver cancer; vaccinating boys and girls against HPV, which will prevent cervical cancer in women; also having regular mammograms will detect breast cancer earlier and improve breast cancer survival rates.

Dr. Nestor Esnaola, surgical oncologist at Fox Chase Cancer Center at Temple University Hospital, Philadelphia, PA said that the cancer prevention methods just mentioned might not be available in developing countries. Instead of mammographies repeat breast self-examinations are more important there. Campaigns against smoking can be utilized in order to prevent cancer of the lungs, the throat and neck. And if colonoscopies are not available, stool samples can be tested for blood and hemoglobin to check for colon cancer.

Different cancer rates increased in women in different countries

There are different cancer types that make the top chart for different countries. For instance in 2012 breast cancer was on top of most countries worldwide as the number 2 killer behind heart attacks and strokes. But other cancers ranked fairly high as well as causes of death: colorectal, lung and cervical cancers.

Despite this trend there were other countries like China and North Korea that had a higher incidence of lung cancer rather than breast cancer. The cancer researchers stated that the reason for this is that the smoking rates are higher in these countries. As already pointed out in China more than ½ of the men smoke, but only a small minority of the women smoke. But women in China are exposed to high amounts of secondhand smoke in addition to environmental pollution, which still causes a lot of lung cancer in women who live in this environment.

In many African countries cervical cancer is very common. Women, who are HIV positive, have a 5-times higher rate of cervical cancer. Southern and eastern Africa where there are higher rates of HIV, have higher rates of cervical cancer.

More data about women’s cancer rates

An overview article entitled “Global Cancer Incidence and Mortality Rates and Trends—An Update” points out some interesting statistics. The greatest numbers of cancer cases and deaths occur among women in Eastern Asia. The estimate for 2012 worldwide was for 1.7 million cancer cases and 1 million deaths in women. China dominated its region with 75% of all female cancer cases and deaths in the region. In North America cancer cases and deaths within the US comprise 90% of the region. The cancer cases and deaths in India make up about 65% of the region of South-Central Asia.

The top mortality rates are found in low to medium income countries, namely in Zimbabwe, Malawi, Kenya, Mongolia and Papua New Guinea.

The most frequently diagnosed cancers in women are breast, lung, and colorectal cancers in economically more developed countries. However, the statistics are different for less developed countries where the top three most diagnosed cancers are breast, cervix, and lung. Similarly the leading causes of cancer deaths for women in developed countries are lung, breast, and colorectal cancers. In developing countries the leading causes of cancer deaths for women is cancer of the breast, lung, and cervix.

Cancer frequencies for women in different countries

The American Cancer Society reports that breast cancer is the most common diagnosed cancer among women in 140 countries. Cervical cancer is most common in 39 countries, all of which are low to medium income countries. There are some countries where other cancer types are more common. For instance in China and North Korea lung cancer is more common among women, in Mongolia and Laos liver cancer, and in South Korea it is thyroid cancer.

The most common cause of death from cancer in women is breast cancer in 103 countries, cancer of the cervix in 43 countries and lung cancer in 27 countries. Other most common cancer deaths in women are in the following countries:

  • Stomach cancer: in Bhutan, Peru, El Salvador, Guatemala, and Tajikistan
  • Liver cancer: in Laos, Mongolia and The Gambia
  • Colorectal cancer: in Japan and Slovakia
  • Esophagus cancer: in Turkmenistan.

Prevention and early detection

Changing the risk factors could modify 20% of breast cancer mortality worldwide. Avoiding excess body weight, physical inactivity and reducing alcohol consumption could all significantly reduce breast cancer mortality. For instance, women with a body mass index of greater than 35.0 have a 1.6-fold higher risk of breast cancer and a 2.1-fold higher mortality rate from breast cancer than women with a body mass index of less than 25.0.

Regular breast cancer screening with mammography is another tool that will reduce breast cancer mortality as the cancer is diagnosed earlier and treated at an early stage where it can often be cured. The WHO recommends for those countries where mammography programs are established that screening should be done only every two years and only between the ages of 50-69 to avoid X-ray over exposure.

Early detection, like for any cancer is the key for successfully treating breast cancer. When there is an early diagnosis of breast cancer, surgical removal in healthy tissue (lumpectomy) often cures breast cancer. Unfortunately in low to medium income countries the cancer is often found too late, requires more invasive mastectomies and radiotherapy and has a lower survival rate than in developed countries.

Cervical cancer

Cervical cancer accounts for the 4th most frequently diagnosed cancer in the world. In 2012 there were 527,600 cases of cervical cancer worldwide and 265,700 deaths from cervical cancer occurred in the same year. 90% of cervical cancers occur in developing countries with India accounting for 25% of the total cases. The key in detecting cervical cancer is a regular screening program. In developed countries where this has been in place cervical cancer incidence has decreased by 80% in 4 decades. At the other end of the spectrum are countries like Uganda, Zimbabwe, and some countries of Central and Eastern Europe where cervical cancer rates have been climbing.

Human papilloma virus

The reason for the spread is that the human papillomavirus (HPV) is now more common and screening methods for cervical cancer are not in place. HPV 16 and 18 are the most common carcinogenic subtypes of the human papilloma viruses; they are responsible for 70% of cervical cancers worldwide. Vaccinating teenagers before they engage in sex is a powerful tool to interrupt the infectious spread of an important risk factor for cervical cancer.

Cervical swab for HPV-DNA test

Instead of the traditional Pap test from the past the new test that is in use now is an HPV-DNA test, a cervical swab that will detect DNA from HPV directly. It is more sensitive than the traditional Pap test. If the HPV-DNA test is positive, the patient sees a gynecologist who performs a colposcopy test. This is a microscopic exam of the cervix. The gynecologist can use several effective treatment methods like a loop electrosurgical excision procedure, laser ablation therapy, cryotherapy or conization for deeper cervical cancer lesions.

As with any cancer early detection and treatment is paramount with cervical cancer. In developed countries the 5-year survival rate is 60 to 70%. In India the 5-year survival rate is 46%.

Cancer of the lung

In 2012 there were 583,100 cases of lung cancer in women worldwide and 491,200 died from it. Lung cancer is the second leading cause of cancer death in women and the third most common cancer. The statistics of lung cancer reflect the tobacco epidemic. It takes about 20 to 30 years after widespread smoking begins in a country before the deadly statistics set in. The peak of the cancer epidemic and the heart attack rates occurs about 30 to 40 years following the peak of smoking in that population.

Lung cancer rates globally

Lung cancer rates in women have lagged behind men, because women as a group have started smoking later. In places like Hong Kong, the United Kingdom, Australia, and the United States women started smoking earlier, and they are in the process of declining their smoking habit or quitting. The new lung cancer cases and also the lung cancer mortality rates are reflecting this. Sadly, in many countries of Europe and Latin America women started smoking much later and they are still increasing their lung cancer statistics and mortality rates. Lung cancer killed 1.1 million men and 0.5 million women worldwide in 2012. Cancer epidemiologists estimate that in addition there are 21,400 lung cancer deaths annually from second-hand smoke in non-smokers worldwide.

Other causes of lung cancer

Beside smoking there are other risks causing lung cancer. The estimated risk for women to die in millions is: exposure to household air pollution, 1.6; outdoor air pollution, 1.4; second-hand smoke, 0.35; occupational risk factors, 0.10; and residential radon, 0.03.

Cancer Rates Increased In Women

Cancer Rates Increased In Women

Conclusion

Women are still in the midst of a global increase of cigarette smoking, which starts often with female teenagers. As long as the smoking rate goes up there will be more breast cancer, lung cancer and cervical cancer. The American Cancer Society provided a detailed review of various cancers and how they are still increasing worldwide, because nobody pays attention to preventative measures. A simple step to prevent cancer is to quit smoking. Another step is to engage in regular physical activity. Finally keeping your body mass index under 25.0 is a third step that can be done by adopting a Mediterranean diet.

There are several pockets within the developed countries where cancer rates are coming down, which is encouraging. I illustrated this complex topic by giving an initial overview and then three examples of breast cancer, cervical cancer and lung cancer.

Electronics In The Bedroom

There is new research showing that electronics in the bedroom can interfere with a normal sleep pattern. Dr. Ben Carter is the lead author and a senior lecturer in biostatistics at King’s College London. He just completed a study involving 125,198 children with an average age of 14½ years. There were about equal amounts of males and females. Both sexes had the same problem. When they were allowed to use electronic media, this interfered with their sleep time. What electronic devices are we talking about? Watching TV, using the computer, the cell phone, tablets and computer games. The study was originally published at JAMA Pediatrics.

Result of the study on electronics in the bedroom

  1. When media bedtime use was allowed, there was a 2.17-fold higher risk of not getting enough sleep quantity. This was compared to kids who did not use media devices in the bedroom.
  2. There was a 1.46-fold risk of having poor sleep quality.
  3. There was a 2.72-fold risk of excessive daytime sleepiness.
  4. Even children who had access to media use, but did not use it at night had similar findings. They had a risk of 1.79-fold to get inadequate sleep quantity. There was a 1.53-fold risk of poor sleep quality. And excessive daytime sleepiness was present with a 2.27-fold risk.

Melatonin level influenced by electronics in the bedroom

Physicians researched the diurnal hormone rhythm and sleep pattern for decades. Essentially two hormones work together.

In the morning when you open your eyes, light enters our eyes and is registered in the hypothalamus. There are also links from the hypothalamus to the pineal gland, where melatonin is synthesized and stored. The light signal stops the secretion of melatonin from the pineal gland, although it is still being produced during the day in the pineal gland, but stored there until the evening hours set in. You may have noticed that you start yawning when the light dims in the evening. That’s when melatonin is released into your system to let you know it’s time to slow down and go to sleep.

Balance of melatonin and cortisol

Of course, we have electrical light and can turn night into day if we choose to! This works for a limited time, but eventually tiredness sets in, and melatonin wins the upper hand. Melatonin is the master hormone of the circadian rhythm.

It is interesting to note that cortisol does exactly the opposite. Cortisol is the adrenal gland hormone that helps us cope with stress. When we are fully awake, we need cortisol to cope with the various stress situations of the day. Melatonin inhibits cortisol secretion and cortisol inhibits melatonin secretion, and they are natural opponents working together for your common good. This is part of the circadian rhythm. We can measure these hormones, and this is how researchers have found out how these two hormones work together.

What light stimulation does to your hormones

Too much exposure of children or adults to electronic devices overstimulates the brain and sends signals to the adrenal glands to produce more cortisol. In between the hypothalamus and the adrenal glands a cascade of hormones regulates this. The hypothalamus sends CRH, the corticotropin-releasing hormone to the pituitary, which stimulates in turn the release of the messenger hormone ACTH to produce more cortisol in the adrenal glands. It is the extra cortisol that keeps kids awake. The same applies to adults who invite electronics into their bedroom. All the excitement from watching the various media gadgets leads to extra cortisol. And we just learnt that cortisol counteracts melatonin. 

What can parents do about electronics in the bedroom?

First of all, parents need to be firm with their kids. They need to explain to them that electronics are staying out of the bedroom. There needs to be a cooling down period one hour before bedtime where they do not watch TV, use the cell phone or other electronic gadgets. They may rebel against this first, but when they sleep better, they likely will be more agreeable. Here is a list that contributes to better sleep habits and better sleep quality:

List for better sleep habits

  • Ensure that the bedroom is dark, soundproof, and comfortable with the room temperature being not too warm. It is important to develop a “sleep hygiene”. This means going to sleep around the same time each night, to have some down time of 1 hour or so before going to bed and get up after the average time of sleep (for most people between 7 to 9 hours). Sleeping in is not a solution, and an alarm clock will help also to develop a sleep routine.
  • Caffeine drinks, alcohol, nicotine and recreational drugs must be avoided. Smokers should butt out no later 7PM, as nicotine is a stimulant.
  • Getting into a regular exercise program, either at home or at a gym is beneficial.
  • Avoid a heavy meal late at night. A light snack including some warm milk would be OK.

More points for the better sleep habit list

  • It is not a sensible idea to use the bedroom as an office, reading place or media center. It paves the way to the stimulus of the cortisol effect that keeps us awake. The bedroom is a place of rest and should be comfortable and relaxing.
  • Some sleepers wake up at night, and they are wide-awake! Leaving the bedroom and relaxing in the living room for a while can help. It goes without saying that playing video games will not help! An alternative is to take 3 mg of melatonin, which will helps to fall asleep faster, but melatonin will wear off after about 4 hours.
  • A self-hypnosis recording is a useful adjunct to a sleep routine. Listening to it before going to sleep helps to focus on relaxation and to stop ruminating about the day and its events. Keep the volume low.

Some thoughts about sleep aids after electronics in the bedroom are removed

Sometimes an adolescent will have trouble falling asleep. Here is the solution of what to do: at the time the youngster is having problems sleeping, there is too much cortisol on board, which prevents the pineal gland to release melatonin. What is missing is melatonin.

The first step is to take 3mg of melatonin at bedtime. It takes 20 to 30 minutes for melatonin to take effect. If the youth does not fall asleep within that time frame he or she is likely thinking too much. If that were the case, I would recommend taking 1 or 2 capsules of valerian root (500 mg strength) from the health food store. This combined with the melatonin should help in more than 80%-90% of insomnia cases. If the child still cannot sleep, see your physician. The adolescent may need sleep studies done or may have problems with the thyroid (hypo- or hyperthyroidism), which may need to be checked. Physicians need to check out other medical problems, including depression. Melatonin and valerian are safe. Other sleeping pills have multiple side effects including memory problems.

Electronics In The Bedroom

Conclusion

A new study has shown that electronics in the bedroom will often keep children awake. It has become a huge problem in schools where students fall asleep or have problems paying attention. There are simple rules regarding a quiet bedroom without electronics that will go a long way of rehabilitating a child who has sleeping problems because of electronics. There are natural ways to help nature along, if the simple measures don’t work. Melatonin and valerian root help to calm the mind and help catching some healthy sleep. If the problem were persisting, an appointment with the family physician would be in order.

Even though this article deals with children and adolescents and the use of electronics in the bedroom, the same applies to adults. They are not immune to the stressors that disrupt sleep. They are just as likely to feel tired and sluggish after a restless sleep, and their performance at the workplace will suffer. Sleep hygiene is as important for adults as it is for adolescents.
