What Electronic Cigarettes Do to You

By | e-cigarettes, heart attack, Lung Disease, Prevention

A review paper of Canadian researchers showed what electronic cigarettes do to you. They can be an effective smoking cessation aid for motivated smokers who eventually want to quit. But when people continue to inhale electronic cigarettes, their use can cause heart attacks, strokes, high blood pressure and increased heart rates. With regard to the lungs electronic cigarettes can cause vaping-associated lung disease, obstructive pulmonary disease, asthma and chronic cough. A literature review showed that e-cigarettes are less harmful to the heart and the lungs than smoking combustible cigarettes.

Increased use of e-cigarettes in younger people

In Canada the 2017 Canadian Tobacco, Alcohol, and Drugs Survey, which included all ages, found that 15.4% tried e-cigarettes. But among adolescents between 15 to 19 years old 22.8% were using e-cigarettes. For young adults aged 20 to 24 the figure of e-cigarette users was 29.3%. In addition, there was a significant increase of Canadian adolescents aged 16 to 19 from 29.3% in 2017 to 37.0% in 2018. Data from the US shows similar trends. E-cigarette use among US high school students increased from 11.7% in 2017 to 27.5% in 2019.

Some facts about e-cigarettes, cigarette smoking and smoking cessation

  • First, researchers noted that the smoking of e-cigarettes has a 3.62-fold risk of leading to subsequent cigarette smoking.
  • Second, a UK study found that when people used e-cigarettes for smoking cessation, 80% of the e-cigarette group were still smoking e-cigarettes after 1 year. In contrast, only 9% of those who used traditional nicotine replacement therapy (Nicorette etc.) to quit smoking were still using nicotine replacement after 1 year.
  • One study compared heart attack rates in a group of regular cigarette smokers and compared this to e-cigarette smokers. Cigarette smokers had a 2.72-fold higher heart attack rate than non-smokers, while e-cigarette smokers had a 1.79-fold heart attack rate compared to non-smokers.

Effect of e-cigarette use on heart and lung disease

Several studies looked at the relationship between e-cigarette use, heart attacks and strokes. There was a 1.4-fold higher incidence of coronary artery disease in e-cigarette smokers in comparison to non-smokers. The e-smokers had a 1.71-fold higher stroke incidence and 1.59-fold higher heart attack rates. In a large metaanalysis done with e-cigarette smokers, researchers noted the following facts: Electronic cigarette smokers were compared to non-smokers. Researchers noted a 2.27-fold increase of the heart attack rates in e-cigarette smokers. There was a 2-fold elevation of the systolic and diastolic blood pressure in e-cigarette smokers.

Switching from cigarette smoking to e-cigarettes

Patients who switched from tobacco smoking to chronic electronic cigarette use had a 7-fold reduction of their systolic blood pressure and a 3.65-fold reduction of their diastolic blood pressure. The researchers concluded that switching from cigarette smoking to e-cigarettes had some merit in terms of risk reduction for cardiovascular disease. But the final judgment on this is still pending. Certainly, quitting entirely from cigarette smoking is the best choice. I reported previously that e-cigarette smokers find it difficult to quit completely and if they smoke conventional cigarettes to stop that.

Effect of e-cigarettes on lungs

In addition to cardiovascular effects there is a direct effect from e-cigarette smoking on the bronchial tubes and the lungs. The vaped substances from e-cigarettes contain a lot of noxious gases that irritate the lining of the respiratory tract. This syndrome is called EVALI (electronic vaping associated lung illness). In 2019 and 2020 there was a rush of EVALI cases in the US with 2807 hospitalizations and 68 deaths. In Canada there were 19 cases of EVALI, 15 hospital admissions, and no deaths. Patients with EVALI have problems breathing, they cough and they have chest pain. Researchers suspect that vitamin E acetate and tetrahydrocannabinol are the major culprits that cause EVALI. But at this time there is no definite proof for that.

Poor quality of vaping fluid from the black market

These substances are not present in commercial e-cigarettes, but when you buy vaping fluid on the black market, it is often mixed in. Prolonged use of e-cigarettes can cause changes on spirometry, such as chronic obstructive pulmonary disease (COPD). Chronic use of e-cigarettes may cause premature onset of COPD.

What Electronic Cigarettes Do to You

What Electronic Cigarettes Do to You

Conclusion

E-cigarette use is increasing at an alarming rate among youths and persons who never smoked. The emerging evidence from researchers showed that there is a risk when you expose yourself to the smoke of e-cigarettes. There is an association of both heart disease and respiratory disease to e-cigarette smoking, but the risk is less than with exposure to regular cigarette smoke. Some researchers think that a switch from cigarette smoking to e-cigarettes could provide a viable harm reduction strategy for some smokers. But unfortunately, many continue to smoke e-cigarettes instead of quitting altogether. And in this case the risks for heart disease and lung disease remain!

Being A Morning Person Can Prevent Depression

By | Anxiety, Cancer, Cardiovascular disease, Circadian rhythm, coffee, depression, Gastrointestinal Disease, heart attack, Insomnia, Lung Disease, Mortality, neurological disease, telomeres

A British study concluded that being a morning person can prevent depression. It was reviewed also in CNN. The study used sleep data from 85,000 UK participants in the Great Britain Biobank Study. They wore wrist activity monitors that provided sleep data. Researchers compared the sleep data with the self-reported mood changes. They found that if the sleep pattern is misaligned with the circadian rhythm, those who are night owls are at a higher risk of developing mood disorders. The controls were those who were morning persons. They were not affected by the misalignment effect.

Normal sleep pattern

Natural sleep habit or the circadian rhythm starts between 10 PM and 11 PM and continues for 7 to 8 hours. Your hormones are replenished during your sleep. This helps your body’s hormones and the immune system to restore itself overnight.

“The health problems associated with being a night owl are likely a result of being a night owl living in a morning person’s world, which leads to disruption in their body’s circadian rhythms”. This is what sleep specialist Kristen Knutson said. She is an associate professor of neurology and preventive medicine at Northwestern University Feinberg School of Medicine.

Reclaim your natural sleep habit

The key is to learn to live within your circadian rhythm pattern. Caffeine is a powerful stimulant and will stop you from falling asleep. For this reason, it is best to avoid caffeine-containing beverages. If you cannot live without your favourite cup of java, switch to the decaffeinated version. Stop using LED lights (from TV, computers, tablets or smartphones) 2 hours prior to your bedtime. Use dark curtains and enjoy a comfortable bed. Maybe read that thriller, earlier in the day instead of making it your bedtime story. And do yourself a favour: you do not need the eleven o’clock news on TV!  They will probably stop you from falling asleep. Go to sleep between 10PM and 11PM.

Children can have problems with sleep disturbances and depression

Another study published March 22, 2021 in the Jama Network showed that depression had an association with sleep disturbances in youth and children.

A meta-analysis of 16 publications looked at depression and disturbed sleep. It showed that depression was 1.5-fold higher in sleep disturbed youths/children compared to controls with a normal sleep pattern.

Other studies re. being a morning person can prevent depression

Another study with Dr. Knutson as the lead author appeared in 2018. The authors found that various health conditions, mood disorders and mortality were on the increase the more the sleep rhythm deviated from the circadian rhythm. Morning persons were protected from this effect. But night shift workers and night owls were at a higher risk of disease. Specifically, they found the following associations for evening types.

  • Evening types compared to morning types had a 1.94-fold risk of psychological disorders
  • The risk of diabetes was 1.30-fold for evening types
  • Neurological disorders had a 1.25-fold risk in evening types
  • Gastrointestinal/abdominal disorders occurred 1.23-fold more often in evening types
  • respiratory disorders were 1.22-fold more common in evening types
  • Evening types had a 10% increased risk of all-cause mortality

The researchers concluded that externally imposed timing of work and social activities has potentially serious health consequences.

Circadian misalignment responsible for disease

Dr. Knutson also said: “Circadian misalignment could also lead to inadequate sleep duration and quality, which could also impair mood and exacerbate mood disorders.”

In other words, circadian misalignment to circadian rhythm problems. This can cause mood disturbances, but eventually lead to the diseases listed above.

Evidence of health risks in night shifts workers

The medical literature is full of examples that the health of night shift workers is significantly affected by circadian misalignment. Here are a few examples.

1.Here is a random selection to illustrate the health risks of night shifts workers. A study from 2015 examined the sleep patterns of 315 shift nurses and health care workers in Iranian teaching hospitals. They found that 83.2% suffered from poor sleep and half of them had moderate to excessive sleepiness when they were awake.

2.This South Korean study examined 244 male workers, aged 20 to 39 in a manufacturing plant. Researchers compared blood tests from daytime workers to blood tests from night shift workers. They also obtained inflammatory markers like the C-reactive protein and leukocyte counts. Night shift workers had significantly higher values. The investigators concluded that shift workers have increased inflammatory markers. This is a sign of a higher risk of developing cardiovascular disease in the future.

Higher mortality and higher cancer risk in nighttime workers

3. A Swedish study found that white-collar shift workers had a 2.6-fold higher mortality over a control group of daytime white-collar workers.

4. Another study compared night workers in the age group of 45 to 54 with daytime workers and found a 1.47-fold higher mortality rate in the night shift workers.

5.In a study from China 25,377 participants were part of a study that investigated cancer risk in males with more than 20 years of night shift work. They had a 2.03-fold increased risk to develop cancer compared to males working day shifts. Women with night shift work in this study showed no effect with regard to cancer development.

Healthy telomeres with healthy sleep pattern

It is true that you can suffer multiple health problems, as all of your hormones depend on the resetting during your deepest sleep between 2AM and 4AM triggered by the nighttime melatonin response. Even your telomeres, the caps of chromosomes in every cell get shortened from too much stress and too little sleep.

One example of such a study comes from Milan, Italy. https://oem.bmj.com/content/75/Suppl_2/A480.1

In this 2018 study researchers compared 46 nurses who had worked in night shifts with 51 nurses working day shifts. Among the night shift workers breast cancer was common, but not among day workers.

Shortened telomeres, hypomethylation of BRC1 gene and p53 gene

In the night shift nurses from Milan there was hypomethylation of the breast cancer gene BRC1. There was also hypomethylation of the general cancer gene p53. At the same time significant telomere shortening occurred in night shift nurses who had worked night shifts for more than 15 years. This likely all worked together in causing night nurses to develop breast cancer more frequently.

Shortened telomeres mean a shortened life span. The reason for this is that people with shortened telomeres develop heart attacks, strokes and cancer. This is what shortens the life span. How do we avoid this risk? Go back to healthy sleep habits. As mentioned above it is best to start going to sleep between 10PM and 11PM and sleep for 7 to 8 hours. Night owls delay going to sleep by 2 to 3 hours.

Being A Morning Person Can Prevent Depression

Being A Morning Person Can Prevent Depression (click image to enlarge)

Conclusion

A publication in Molecular Psychiatry demonstrated that evening person (night owls) are more likely to develop depression. This is in comparison to morning persons. As discussed, other researchers showed that evening persons also can develop diabetes and neurological disorders. In addition, respiratory disorders and gastrointestinal disorders are more common in night owls as well. When it comes to mortality, evening persons have a 10% increase of mortality over morning persons. There is a large body of literature regarding diseases of night shift workers. Night Shift work is perhaps the most extreme example of a circadian misalignment. It leads to poor sleep, inflammation in the body, increased cancer risk and higher mortality compared to day shift workers.

Prevent telomere shortening

Even the telomeres get shortened in night owls and night shift workers. We can prevent problems like these by going to bed in time and sleeping according to our circadian rhythm. If you had a poor night’s sleep, make up for it with the help of an afternoon nap. Do not sleep all afternoon though; half an hour or one hour will be enough. Even a short, restful nap after coming home from work can restore your feeling of wellness.

How to Manage Clot Formation with Covid-19

By | blood clots, heart attack, immune system, Infectious Disease, Inflammation, Lung Disease, Mortality, Stroke

A publication in the Canadian Medical Association Journal describes how to manage clot formation with Covid-19. A significant amount of cases among Covid-19 patients come down with clotting problems. This means that an infection with SARS-CoV-2 (or Covid-19 coronavirus) may initially present with a fever and cough. But a few days later it can suddenly turn into a dangerous disease with severe clots, multiple organ failures and death.

Clot occurrence with Covid-19

It is important to realize that most patients with SARS-CoV-2 do not need hospitalization. But physicians admit 10 to 15% of patients to the hospital. Of these 20% end up with treatment in the Intensive Care Unit (ICU). Of all the hospitalized patients between 5% and 30% develop some form of thrombotic event. Notably, complications of clot formation can be a stroke, a heart attack, a pulmonary embolism or a deep vein thrombosis in the leg. In a recent study from the US 400 random hospitalized patients with Covid-19 144 patients were admitted to the ICU. 4.8% had radiologically confirmed deep vein thrombosis. Overall there were 9.5% with thrombotic events that developed during the hospital stay.

How does a coagulopathy develop with Covid-19?

Truly, SARS-CoV-2 enters the body cells through an interaction of its viral spike protein with the angiotensin-converting enzyme 2 (ACE2) receptor. To explain, numerous organs and tissues express this receptor. This includes lung alveolar type 2 epithelial cells, endothelium, the brain, heart and kidneys. To emphasize, ACE2 leads to angiotensin II degradation. With the SARS-CoV-2 stimulation of the ACE2 receptor there may be an accumulation of angiotensin II, which causes a procoagulant state. Injury of the endothelium explains inflammation in the lining of the blood vessels in multiple organs. Commonly affected organs are lungs, heart, kidneys and intestines. The inflammatory reaction is what can lead to clot formation. When part of an organ has died off because of mini clots that destroyed part of the organ, this process can eventually lead to organ failure. Lung failure, heart failure and kidney failure can develop in these sick patients.

Adequate vitamin D blood levels are important for the immune system

By all means, vitamin D is very important for the integrity of the immune system. With vitamin D blood levels below 15 to 20 ng/mL (37.5–50 nmol/L) the immune system is paralyzed, and any viral or bacterial infection tends to overwhelm the body. Of course, this is the reason why the mortality due to Covid-19 coronavirus is highest in patients with these low vitamin D blood levels. People with secondary illnesses (diabetes, arthritis, autoimmune diseases, cancer) and patients above the age of 60 have the lowest vitamin D blood levels and have the highest mortality rates. This publication describes this in more detail.

Best vitamin D blood level is in the upper normal range (50-80 ng/mL)

Above a vitamin D blood level of 30 ng/mL (=75 nmol/L) a patient’s immune system is functioning normally. However, the immune system is strongest at a vitamin D blood level of 50–80 ng/mL (125–200 nmol/L), which is the upper range of the normal level for vitamin D in the blood.

Keep in mind that vitamin D toxicity occurs only above 150 ng/mL (375 nmol/L).

Specific effects of vitamin D on Covid-19

There are three major effects that vitamin D has.

  1. A strengthening of the epithelial barrier not allowing the coronavirus to penetrate into the lung tissue as easily.
  2. Release of defensins and cathelicidin, two crucial antiviral polypeptides that eradicate any virus in the system.
  3. Interruption of the “cytokine storm”, an overwhelming inflammation which is responsible for viral pneumonia to develop. Without the cytokine storm there is no damage to the lungs and people do not need treatment in the ICU. This is particularly important for people above the age of 60 and for people with pre-existing diseases.

In like manner, with the stabilizing effect of vitamin D regarding the immune function more severe forms of Covid-19 can turn into less severe forms with a better outcome.

Treatment of patients with Covid-19 who have clotting problems

Patients need to be assessed with respect to their risk of developing clots. This publication describes that high risk patients have elevated D-dimer levels. When blood clots dissolve the body produces D-dimer, a protein fragment. Normally the D-dimer test is negative in a person that does not produce clots. But in sick patients with Covid-19 who form clots this blood test typically shows D-dimer >2500 ng/mL. In addition the tests show high platelet counts (more than 450 × 109/L), C-reactive protein (CRP) >100 mg/L and an erythrocyte sedimentation rate (ESR) >40 mm/h.

Indeed, with this constellation of blood tests in a severe Covid-19 case in the ICU setting, the physician uses heparin intravenously or subcutaneously to counter clot formation. However, this needs to be balanced against the risk of causing severe internal bleeding.

Separate from the anticoagulant effect, heparin seems to also suppress inflammatory cytokine levels. In addition, heparin suppresses neutrophil chemotaxis and migration. Physicians rescued many patients from death using heparin therapy.

Risk versus benefit clinical trials of heparin therapy are required

At this point there are only retrospective clinical trials available to describe risk versus benefit of heparin therapy. Some show no difference, others do. There are two international clinical trials on their way to shed more light on this situation. Until the results of these clinical trials are available, physicians need to treat patients to the best of their knowledge.

How to Manage Clot Formation with Covid-19

How to Manage Clot Formation with Covid-19

Conclusion

Clot formation in sick Covid-19 patients is responsible for many deaths in Covid-19 patients. The SARS-CoV-2 (or Covid-19 coronavirus) causes a cytokine storm with injury to the lining of the arteries. This can affect multiple vital organs and the condition may lead to organ failure. This activates the clotting system and causes clots all over the body. When this process occurs, patients get very sick and the death rate climbs. Physicians were able to rescue some patients with heparin therapy. Two international clinical trials are on the way. Hopefully  these trials answer questions about this newer treatment method. The downside of heparin therapy is the complication of massive bleeding, which causes deaths as well. When it comes to Covid-19, don’t rely on curative medicine. Strengthen your immune system by preventative therapy like vitamin D3 that can interrupt the cytokine storm.

And even with a “well-prepared” immune system it is extremely important to follow all the guidelines of distancing, disinfecting and wearing face masks. We need all the help we can get!

Poor Diets Threaten Americans and Cause Diseases

By | alcohol, Alzheimer’s disease, Cardiovascular disease, diet, exercise, fish oil, Fitness, food, heart attack, Hormones, lifestyle, Lung Disease, Nutrition, Obesity, polyunsaturated oil, Smoking, Stroke, sugar

A new Federal Nutrition Research Advisory Group stated that poor diets threaten Americans and cause diseases. More than 500,000 people in the US are dying every year because of poor nutrition. 46% of adults have unhealthy diets; but children have even more, namely 56%. In 1979 the US healthcare cost was 6.9% of the gross domestic product. Compare this to 2018 when the US healthcare cost was 17.7% of the gross domestic product.

The Federal Nutrition Research Advisory Group states: “Poor diets lead to a harsh cycle of lower academic achievement in school, lost productivity at work, increased chronic disease risk, increased out-of-pocket health costs, and poverty for the most vulnerable Americans.”

You can improve your diet quality 

When you start cutting out junk food and other processed foods, the quality of your food intake is improving. Eat more vegetables, and fruit. Eat wild salmon, which provides omega-3 fatty acids. Do not consume vegetable oils like soybean oil, canola oil, safflower oil, corn oil and grapeseed oil. They all contain omega-6 fatty acids. Omega-6 fatty acids are essential fatty acids and they convert mainly into energy. But the problem is that our western diet contains too many omega-6 fatty acids. Omega-6 fatty acids can convert into arachidonic acid, which causes inflammation. This in turn can cause heart attacks and strokes on the one hand and arthritis on the other. Use cold-pressed extra virgin olive oil instead for cooking and on salads.

How does poor quality food affect your health?

Researchers are aware of trans fats causing Alzheimer’s disease, heart attacks and strokes for a long time. They increase the bad LDL cholesterol, decrease the good HDL cholesterol. Rancid oils contain free radicals that oxidize LDL cholesterol and attack the lining of your arteries through small dense LDL cholesterol. The FDA has started to initiate steps in 2015 to make the use of trans-fats in the food industry illegal. Completion of this in the US occurs in early 2020.

Japanese trans-fat study (Alzheimer’s disease)

This Japanese study followed 1,628 Japanese community residents (men and women) for about 10 years. Researchers used the typical trans fatty acid, elaidic acid to monitor the accumulation of trans fats in patients. This is possible with a simple blood test, which serves as a marker for industrial trans fats. 377 participants developed dementia (247 Alzheimer’s disease and 102 vascular dementia). Based on the blood elaidic acid levels earlier in the study individuals with higher trans-fat levels were more likely to develop Alzheimer’s disease as the study progressed. Patients whose trans-fat blood levels were in the higher range were 50% to 75% more likely to develop Alzheimer’s disease or dementia.

Diseases caused by poor lifestyle habits

It is important to review the diseases that shorten life expectancy due to having poor lifestyle habits. Note that it is not only your dietary habits that determine this, but in addition, several lifestyle factors.

Cardiovascular disease

Smoking, lack of regular exercise and poor eating habits result in being overweight or developing obesity. All of these are risks with LDL cholesterol elevation and HDL cholesterol lowering that leads to heart attacks and strokes. Here is a study that shows how life is shortened after a heart attack. It is clear from this how important it is to give up all of the poor lifestyle habits to avoid this from happening.

Cancer

90% of lung cancers are the result of cigarette smoking. Heavy drinking can contribute and also lead to cancer of the liver, esophageal cancer, cancer of mouth and throat and cancer of the breasts in women. In addition, consuming too much alcohol causes cancer of the colon and rectum in both sexes.

Diabetes

There are a variety of risk factors causing diabetes. Obesity, a lack of exercise, a bad diet with too much carbohydrates and the aging process are what contributes to the development of type 2 diabetes.

We see again that it is largely lifestyle issues that drive the onset of this disease. People who have developed diabetes need to control their blood sugar very closely to avoid complications of diabetes. This includes making healthier choices.

Otherwise complications of diabetes are diabetic nephropathy, blindness from macular degeneration of the cornea, heart attacks, stroke and diabetic neuropathy. In addition, vascular complications also include artery occlusions in the lower extremities with frequent foot or below knee amputations.

Chronic diseases

Often chronic diseases develop when there is generalized development of inflammation. COPD, chronic kidney disease and arthritis are examples of such conditions. In addition, Alzheimer’s disease, arthritis, asthma, Crohn’s disease, cystic fibrosis and diabetes belong into this category. All of these chronic diseases have in common that cytokines produce inflammation in the body. This keeps the chronic disease going and makes it more difficult to cure. When the person with a chronic disease makes poor lifestyle choices, the inflammation just becomes more chronic.

Smoking is one of the factors that makes chronic inflammation more chronic. Having a body mass index above 25.0 (being overweight) and above 30.0 (obesity) also creates more inflammation in the body. Excessive alcohol intake damages body cells and releases free radicals. These in turn cause inflammation and make the chronic disease more difficult to treat. An unhealthy diet tends to raise the bad LDL cholesterol, introduces pesticides and other chemicals into your system and adds to chronic inflammation. Finally, a lack of exercise is not contributing to a healthy circulation and lowers the protective HDL cholesterol, paving the way for heart attacks and strokes.

Poor Diets Threaten Americans and Cause Diseases

Poor Diets Threaten Americans and Cause Diseases

Conclusion

A new Federal Nutrition Research Advisory Group has been formed, which noted that many Americans follow very poor diets. 46% of adults in the US have unhealthy diets; but children have even more poor diets, namely 56%. This is of concern, because in time this causes a variety of diseases discussed here. Instead of just treating the symptoms of these diseases, it is important to improve the diet people are on, which prevents the development of these diseases. A well-balanced diet not only prevents diseases, it also leads to longevity and healthy aging without Alzheimer’s disease. Take care of what you eat, and be sure it is healthy!

Adequate Vitamin D Level Strengthens the Immune System

By | immune system, Infectious Disease, Inflammation, kidney disease, Lung Disease, Mortality, Prevention, Vitamins and supplements

The Covid-19 coronavirus crisis is teaching us that an adequate vitamin D level strengthens the immune system.

When we age, our resistance to infections weakens, but this may be because our immune system needs more vitamin D3. I have reviewed the super powers of vitamin D3 before in 2014. In the past the thought was that the human body would need only 400 IU of vitamin D3 every day to cure rickets. And these were the daily vitamin D3 recommendations from medical authorities for several decades. Gradually it became known that for cancer prevention, infection prevention, cardiovascular illness prevention and for diabetes prevention much higher doses of vitamin D3 were necessary. As pointed out in the previous link, almost 50% of the world population is deficient in vitamin D. This is due to a lack of exposure to sunlight and due to inadequate supplementation with vitamin D3.

History of vitamin D

Dr. Adolf Windaus received the Nobel prize for chemistry in 1928. It was to acknowledge “… his studies on the constitution of the sterols and their connection with vitamins”. His work involved the metabolism of vitamin D and the precursors of vitamin D.

Rickets

As the above link shows, rachitic children were treated since the mid 1800’s with cod liver oil and since the early 1900’s also with ultraviolet light. But we know now that 400 IU of vitamin D3 per day is just enough to cure rachitic children, but it is not enough to strengthen the immune system to fight influenza viruses or the Covid-19 coronavirus. I will discuss further below what vitamin D blood levels are important to achieve a healthy state of the immune system.

Adequate vitamin D level strengthens the immune system

The immune system is very complicated and consists of many cell types that interact with each other and the rest of the body. It is important to recognize that the innate immune system immediately inactivates intruding viruses. But the vitamin D blood concentration has to be high enough. The acquired immunity consists of antibodies that are produced by B cells. The antibodies were produced during prior infections that you have survived and you are now immune to. However, other antibodies that circulate in your blood may have originated from vaccines you received in the past (whooping cough, measles, tetanus, diphtheria etc.). With the Covid-19 coronavirus it is the innate immunity that plays the biggest role until a vaccine will be found in the future.

Vitamin D is a hormone

This 2013 paper explains that vitamin D is a hormone that stimulates its own vitamin D receptor. This is a nuclear receptor that has close relations to the cell DNA and can stimulate more than 900 polypeptides. They are messenger molecules that are involved in a variety of physiological functions. One of the key functions is the immune system. This link explains that T cells that have vitamin D receptors can develop into cytotoxic T cells (also known as “killer T cells”). They are important in fighting cancer, but also parasites.

The key is that the hormone vitamin D can release more than 100 polypeptides that have the power to fight virus attacks including the Covid-19 coronavirus.

Three mechanisms how vitamin D works against the virus

The researchers outlined 3 mechanisms of how vitamin D works:

  • Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate.
  • “Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the blood stream within 1 to 2 days.
  • “…And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” It is people who get the viral pneumonia that are at a high risk of death. By bringing the blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.

Two polypeptides, cathelicidin and defensins

Again, I like to emphasize that it is not vitamin D that has a direct effect on the virus. It is two polypeptides, cathelicidin and defensins, which are powerful antiviral polypeptides, that are released by vitamin D.

They can kill viruses that have invaded the blood stream and can eliminate the cytokine storm. This all happens very fast, within only 1 to 2 days. But you have to have an adequate vitamin blood level for this to occur (about 50-80 ng/mL).

Sources of vitamin D

First of all, vitamin D is readily absorbed from food. But there are not many foods that contain enough vitamin D for the immune system. The ones that contain vitamin D are as follows:

  • “Fatty fish, like tuna, mackerel, and salmon.
  • Foods fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals.
  • Beef liver.
  • Cheese
  • Egg yolks. “

Sun induced amount of vitamin D

Secondly, vitamin D can be synthesized in the skin from exposure to sunlight. But for this to happen all the necessary enzymes need to be present.  This link explains that many older people above the age of 65 have low vitamin D blood levels because of a lack of sun exposure and a lack of cutaneous synthesis because of enzyme issues.

Vitamin D supplements

The most reliable source of vitamin D are vitamin D3 supplements. When people supplement with the same dose of vitamin D3 there will be people who get higher vitamin D blood levels than others, as absorption in the gut is different for different people.  The ones who have relatively low vitamin D blood levels are often called “slow vitamin D absorbers”. But when the vitamin D3 dosage is increased even those people will reach the recommended high normal range (50-80 ng/mL).

Vitamin D blood level

The vitamin D blood test has the scientific name “25-hydroxy vitamin D level”. This is now the recognized gold standard for determining who is deficient or has normal levels with respect to vitamin D. The following 2013 publication has studied the vitamin D level of 1,470 healthy Swiss men and women, 60 years or older. Vitamin D levels were classified as severely deficient when the level was below 10 ng/mL. The vitamin D level was deficient between 10 and 20 ng/mL. The level was insufficient when between 21 and 29 ng/mL. A level above 30 ng/mL is normal.

8 % of the subjects were severely insufficient and 66% had insufficient vitamin D levels. Only 26.1% of the subjects had normal levels. Over 50% of healthy older Swiss (above the age of 70) had insufficient vitamin D levels.

Which vitamin D level is safe and which is not?

A peer-reviewed publication of the effects of vitamin D in health and disease contains 269 references.

What vitamin D level is optimal? This question was reviewed in this paper.

  • Below 15 ng/mL the immune system is paralyzed
  • With a level above 30 ng/mL the immune system is working
  • A level of 50-80 ng/mL has the immune system working optimally
  • Above 150 ng/mL toxic vitamin D levels start
  • With 300 ng/mL severe toxicity begins

Vitamin D toxicity

It is only with high levels of vitamin D (more than 150 ng/mL) that you have to worry about high calcium levels in the blood or kidney stones (toxic levels). But the key is to not exceed 80 ng/mL regarding the vitamin D blood level. This gives you a lot of flexibility before you reach toxic levels (above 150 ng/mL). For those who want more information, here is a thorough, peer reviewed publication about vitamin D toxicity with 59 references.

Vitamin D supplement compliance

The question is why not more people take adequate vitamin D3 supplements.  We know that vitamin D can prevent so many chronic diseases including serious viral infections. The answer is complex, but it includes a fear of the population of vitamin toxicity (kidney stone and high calcium levels). However, as pointed out before, this occurs only above a vitamin D level of 150 ng/mL. With proper vitamin D blood level monitoring you never reach toxic levels of vitamin D.

Denial

Denial likely is another major factor. People feel that if they have a balanced diet, they would be protected from vitamin D insufficiency. As pointed out before this is a grave error to think as our food does not contain sufficient vitamin D to strengthen our immune system.

False security with low doses of vitamin D

Finally, there are people who think that low doses of vitamin D, like 1000 IU of vitamin D daily, would be enough. But it is not enough. This is why testing vitamin D blood levels is so important. It is a reality check. The blood level must be in the high normal range (50-80 ng/mL). At this level the immune system functions optimally.

Compliance issues

In this context there was an interesting study done by LifeExtension, a company that publishes monthly health magazines. In this study the company examined the vitamin D blood levels of LifeExtension members. They are the ones who should be knowledgeable in how important it is to have good, preventative vitamin D blood levels. The study showed that 38% of the vitamin D test results were less than 30 ng/mL. In addition, 69% of the vitamin D tests were less than 40 ng/mL. Finally, 85% of the vitamin D test results were less than 50 ng/mL. What this means is that LifeExtension members were non-compliant when it came to taking regular adequate vitamin D3 doses. This resulted in levels that were too low for the majority to protect them from the Covid-19 coronavirus.

Covid-19 coronavirus infections and vitamin D blood level

There is a tight relationship between vitamin D blood levels and the strength of the immune system. Essentially, coronavirus mortality measures who is vitamin D deficient. Without enough vitamin D on board the virus penetrates into the blood stream and penetrates the lining of the respiratory tract. Next the cytokine storm develops, which leads to viral pneumonia. Higher doses of vitamin D3 will mitigate the course of Covid-19 coronavirus.

Adequate Vitamin D Level Strengthens the Immune System

Adequate Vitamin D Level Strengthens the Immune System

Conclusion

The Covid-19 coronavirus pandemic has taught us how important an intact immune system is to survive the virus when you get it. We do know for some time how closely related a good vitamin D level is with the functioning of the immune system. I have reviewed here what a desirable vitamin D level is and how we can achieve this with oral vitamin D3 supplements. The goal is to achieve a vitamin D level in the upper range of normal (50-80 ng/mL). With a level like this the virus cannot penetrate the mucous membranes of the respiratory tract and even if it did, it cannot produce a cytokine storm in the blood that would lead to the deadly viral pneumonia or to blood clots. When the virus invades the bloodstream, vitamin D releases powerful antiviral polypeptides that can kill viruses within 1 to 2 days.

Four Diseases Cause Most Of The Deaths

By | Angina, Cancer, Cardiovascular disease, Diabetes, Fitness, heart attack, Heart Disease, lifestyle, Lung Disease, Mortality, Nutrition, sugar

Four diseases cause most of the deaths around the world: cancer, cardiovascular disease, chronic respiratory diseases and diabetes. This story is the news right now. 50% of the 193 UN member states that signed a treaty in 2015 are falling short of their promise. They wanted to reduce premature deaths from these diseases by 2030. But this is not happening as this story shows.

I like to review these 4 key diseases and what we can do ourselves about eliminating them. We cannot afford to wait for things to happen on a national level. Rather we need to go to the grass roots of every country and change the risk factors that cause these 4 diseases.

Cancer

First, cancer is a disease of older people, unless strong genetic factors are present. In this case even children can get leukemia, brain tumors and osteogenic sarcoma. In older people DNA mutations and DNA breaks happen more often as we age. On the other hand, if we diagnose cancer in stage 1 or 2 (in the early stages), it is quite often curable.

Oncoblot test, a cancer screening test

Probably one of the less known new criteria is the fact that there is a very sensitive cancer blood test, called the Oncoblot test (released about 4 years ago by the FDA). The latest screening test that came out of the human genome project is called the Oncoblot test. It screens for 25 of the most common cancers. And it is screening for ENOX2 proteins from cancer cells. It is a 1000 USD test in the US that health plans will not cover, but it will screen for more than 25 different common cancers 6 to 8 years before they would otherwise become clinically manifest.

If you discover cancer with this early blood test and you treat it right away, you have a good chance to live a few years longer. You may come down with another cancer down the road, but treat it early again, and you will still have a better life expectancy. Remember: four diseases cause most of the deaths, cancer is one of them!

Cardiovascular disease

Furthermore, people develop cardiovascular disease from poor eating habits and a lack of regular exercise. There are a few percentage points of people with familiar high cholesterol. These people need to see their family doctor for a prescription to lower cholesterol. But the majority of people will do well by changing their diet into a Mediterranean diet; lose weight until their body mass index reaches a value of 21 to 24. With this diet it is important to cut out all refined sugar and starchy foods. Regular exercise in a gym will also prevent hardening of the arteries. Chelation therapy has been shown in this study to help reduce hardening of arteries.

Diabetes patients have accelerated hardening of the arteries

We know from diabetic patients who have accelerated hardening of the arteries how devastating cardiovascular disease can be. Heart attacks, strokes, kidney failure, amputations of the lower leg and blindness are just some examples. Even patients who do not have diabetes can get these complications at an older age. The key is to think preventatively, change the diet, exercise regularly and you will lower all those risks. Remember: four diseases cause most of the deaths; cardiovascular diseases belong to that group and are a major player.

Chronic respiratory diseases

There are different reasons why a person may develop chronic respiratory disease. A common disease is chronic obstructive pulmonary disease (COPD). COPD often has a link to smoking heavily as a younger person. This is where the damage to the lung tissue has started. Exposure to cigarette smoke leads to loss of elastic tissue in the bronchial tubes. The lungs have a difficult time to exhale to get rid of the CO2. The end result is that your breaths are shallow and you can’t get enough oxygen, because the lung is already filled with air.

Asthma and COPD

Another disease is asthma. Nowadays physicians can treat this condition well with a corticosteroid inhaler and salbutamol. Salbutamol dilates the airways by relaxing the muscles of the bronchial tubes. The corticosteroid keeps the lining of the bronchial tubes thin, so that the air can move in and out of the lung.

If asthma is not treated properly there can be permanent damage to the airways and the clinical picture would look similar to COPD.

With end-stage COPD patients the only therapy the physician can offer is continuous oxygen flow treatment. With power failures these machines that supply oxygen will stop working. People need to make provisions to have a back-up generator. Again, we need to remember: four diseases cause most of the deaths. Chronic respiratory diseases belong to them.

Diabetes

Patients with type-2 diabetes (Type 2 DM) are usually older than 30 years of age.

That’s why they are called “mature onset diabetes” or “adult onset diabetes”. For several decades a patient may “incubate” diabetes and have one or more of the diabetes risk factors, such as high blood pressure, obesity, high cholesterol or high triglycerides, but have normal blood sugars.

Physicians have followed patients like this for several decades in the well known Framingham Heart Study and found that a high percentage of them do come down with type-2 diabetes later in life. In the past this time of incubation was termed “pre-diabetes”. Now we call it “syndrome of insulin resistance” or “metabolic syndrome”. Diabetes belongs to the group of diseases that are associated with chronic inflammation in the body.

Causes of type-2 diabetes

Type-2 diabetes often associates with other endocrinological diseases such as Cushing’s syndrome (an adrenal gland hyperactivity) or acromegaly (increased growth hormone production). In these diseases other hormones are tilting the hormone balance by counteracting insulin thus leading to a relative shortfall of insulin, which is another cause for type-2 diabetes. There is confusion among scientists regarding possible genetic reasons for type-2 diabetes. The environment or weight gain may trigger various genetic loci that exist. The syndrome of insulin resistance has shown some connections between hypertension, obesity and type-2 diabetes.

Death in diabetics usually comes from a heart attack, a massive stroke, but it may also come from systemic infections, called sepsis. Dr. Taylor from Newcastle University showed on 30 volunteers that 43% of diabetics could be cured by a diet of 600-700 calories for 8 weeks. The medical literature also knows that regular exercise is beneficial for diabetics. It cannot be overstressed that four diseases cause most of the deaths; diabetes belongs to them and is a major player.

Four Diseases Cause Most Of The Deaths

Four Diseases Cause Most Of The Deaths

Conclusion

Four diseases cause most of the deaths. They were the cause of death for several years. They are cancer, cardiovascular disease, chronic respiratory diseases and diabetes. The secret is to minimize the impact of each of these diseases. You can prevent chronic respiratory diseases by stopping to smoke and treating asthma properly. To treat cancer successfully one needs to diagnose it early and remove it surgically. With cardiovascular disease chelation therapy has shown a difference. Otherwise a regular exercise program and a Mediterranean diet, which has anti-inflammatory qualities, will help. Dr. Taylor from Newcastle University demonstrated that he can treat diabetes with a low calorie diet. Each one of us has a responsibility to do something about our diagnosed condition. We cannot wait for magic cures. We need to do what has known benefits. Hopefully with these short hints will help you to improve your health.

Health Risks After Hurricanes

By | Infectious Disease, Lung Disease, Mortality, Prevention

We hear a lot about the dangers of hurricanes when they are in a region, but very little regarding health risks after hurricanes. I thought it would be interesting to review all of the health risks in a blog.

Health risks during a hurricane

A lot of the health risks during a hurricane are directly related to the risks from the wind severity, the amount of rain per hour and the physical damage from the hurricane. The excessive wind can uproot trees and they may fall right onto a house. This happened in the beginning of hurricane Florence. The amount of rain that comes down in a short time frame can be astounding. It causes flooding, which together with the high wind speeds can make you lose your footing. There is flying debris, torn away pieces of wood and drywall that can become a hazard to any person. It is a hazard that could kill you right there. It is best to be out of the way of a hurricane, if you can at all. But you need to watch hurricane predictions on the Internet or the news, so you know what is going on long before the hurricane arrives. This gives you enough time to travel away from the danger zone. People who live on islands need to be particularly proactive, so that they get out of harms way in time.

Be safe from floodwaters

If you live in a low-lying area, it is safer for you to leave and go to a shelter before the hurricane hits. Otherwise you end up drowning. Being on top of your house in a hurricane is dangerous as the roof may fly off any minute from the force of the wind. You are also the target of flying debris, wood pieces and other flying objects.

Contaminated water is one of the major health risks after hurricanes

With hurricane Maria in 2018 it appeared in the first few days that only 16 to 18 people had died from the physical effects of the hurricane in Puerto Rico. But in the subsequent weeks and months people died en masse because of infections from contaminated drinking water. It is unbelievable that huge water supplies had been brought in by FEMA following the hurricane Maria, but it was not distributed to the people who needed it. The total death toll is now around the 3000 mark. FEMA calculated this by subtracting 13,000 deaths due to natural causes from the total deaths of 16,000. The difference is about 3,000 deaths, attributable to hurricane Maria.

Providing clean drinking water important

Providing clean drinking water should be the first priority following a hurricane. This will prevent that people get the typical water-born bacterial and viral illnesses following a hurricane.

One patient in Puerto Rico with chronic emphysema was on a breathing machine. The interruption of electricity as a result of hurricane Maria meant his death. Some people are so vulnerable that the interruption of electricity ends their life.

Communicable diseases from floodwaters

The WHO has brought out a fact sheet regarding communicable diseases from floodwaters. People need to be aware that floodwaters are contaminated and avoid them as much as possible. However, they also point out that unless you have bruises or cuts where bacteria from contaminated waters could grow the danger is smaller than generally believed.

Mold from water damage to houses

After hurricane Katrina in New Orleans 2005 there was a lot of mold growth in houses that were flooded. This caused an overwhelming odor that was difficult to cope with. Bleach water removes mold initially until a professional crew can clean it up at a later date. I mention this here because following a hurricane there will not be enough professional people around to help. Mold is particularly devastating for asthmatics and people with chronic respiratory conditions. These people need evacuation from such living environments until the house is clean from molds. Flare-ups of asthma and chronic obstructive pulmonary disease can be deadly. Under normal circumstances people with respiratory problems can manage, but these people are at a severe risk of dying from an aggravation of their underlying conditions. Hurricane Katrina will be remembered for this.

Living in destroyed homes

Often with a direct hit of hurricane the roofs of homes are missing. The hurricane ripped them off and they literally flew away. A home without a roof is prone to water damage from future precipitation. There is the danger of mouse and rat infestation. Birds can enter and partake in the leftover meals. Their droppings may contain contagious bacteria like salmonella causing typhoid fever. Builders  work hard and long hours; it can take months or years before life is normal again. It may be wiser to live with a relative for a few months until the house is in livable condition again. When electricity is restored and the water lines are functioning again, there may still be an issue about getting safe drinking water and uncontaminated water to have showers and baths. Also, without proper shelter there are risks of mosquitoes transferring communicable diseases. This happened in the Dominican Republic.

Malaria in the Dominican Republic

In September 2004 Hurricane Jeanne struck the Dominican Republic. Subsequently there was more flooding from heavy rainfalls. The end result was a mini-epidemic of 17 cases of malaria, because the flooded areas gave the mosquitoes more breeding ground to multiply. Fortunately no one died, as all the malaria cases responded to chloroquine and primaquine. But some patients had to be treated in the Intensive Care Unit of a hospital. As already mentioned there are other water born illnesses that can cause diarrhea, vomiting and fever. These people need to get immediate access to a hospital where the medical staff will rehydrate them intravenously. Otherwise they could die.

Health Risks After Hurricanes

Health Risks After Hurricanes

Conclusion

Hurricanes pose enormous problems for the communities where landfall occurs. Close to the eye of the hurricane are the worst structural damages to properties and trees. But even miles away from that there can be flooding due to excessive winds and rain. Most people are reasonable during the initial phase when the hurricane hits. This means they stay inside so they can protect themselves from the direct impact of the storm. But hurricanes can pull roofs off and people can get hurt.

Illnesses from contaminated water

Later there is a disruption of the electrical supply as well as the water supply. The restoration of the utilities may take days or weeks. Immediately you depend on fresh and clean water supply, and when you run out, there may not be enough fresh water available. Illnesses from contaminated water become a huge problem at that point. This is where a lot of mortality comes from in the aftermath of a hurricane.

If you can, it is wiser to escape this all by visiting a relative far away from the hurricane area. In this case you must leave well in time before the hurricane hits. You can check with the authorities when it would be safe to return home. At least you know that you have survived. Everything else can wait. You will gradually take care of it. But it may take a long time for things to return to normal.

Forty Percent Of Premature Deaths Can Be Prevented

By | Cancer, Diabetes, Fitness, Health, heart attack, Heart Disease, High Blood Pressure, Lung Disease, Nutrition, Obesity, Prevention, Stroke, Vitamins and supplements

A new report from the CDC (Center of Disease Control) in the US has revealed that up to 40% of premature deaths could be prevented by simple lifestyle changes. As this link shows every year about 900,000 premature deaths occur in the US, which are due to 5 major diseases that in the opinion of the CDC can be prevented by 20 to 40%. Here are the diseases that kill: cancer, heart disease, COPD/emphysema, stroke and accidents/injuries. These conditions were responsible for 63% of all deaths in the US in 2010.

Let’s discuss each of these conditions and how one could lower the risk of dying from them.

1. Cancer:

The Framingham Heart Study has shown that smoking and cancer are closely related. Smokers who quit can significantly reduce their risk of getting cancer. We also know that exercise and prophylactic supplements like fish oil and vitamin D3 have cancer preventative effects.

Antioxidant supplementation that included beta-carotene, vitamin A, vitamin C, and vitamin E daily or on alternate days for 1 to 12 years, along with selenium supplementation reduced the incidence of cancer of the esophagus, colon, pancreas, stomach or the liver. Insulin resistance due to sugar and starch overconsumption is causing cancer, particularly breast cancer, colorectal cancer and endometrial cancer. I have discussed this in a recent blog.

Pollution has been linked to increased lung cancer risks as discussed here.

2. Heart disease:

Heart disease can be caused by several factors in combination. Lifestyle issues are important: Smokers need to quit smoking as the Framingham Heart Study has shown more than fifty years ago that smoking causes heart attacks. Obesity and diabetes also contribute significantly to the risk of heart disease. Often these are connected to faulty nutrition, which is another lifestyle issue that comes to mind when too much sugar and starchy foods are taken in; your liver will convert these into fatty acids, triglycerides and elevated, oxidized LDL cholesterol, which gets deposited under the lining of the arteries. A lack of exercise adds to this problem as a lack of exercise lowers the protective HDL cholesterol and fat is deposited under the lining of the arteries. Start exercising and your protective HDL cholesterol will rise, your total cholesterol to HDL ratio will lower to healthier levels and your risk for hardening of the arteries and for getting a heart attack will fall. If you have diabetes, it is important that you manage your blood sugars well; this means that if you inject insulin, you want the blood sugar tests to be within the normal range and the hemoglobin A1C values to be below 5.5%. Poorly controlled diabetes is an important cause of heart attacks and strokes. High blood pressure is also an important cause of developing heart attacks and strokes. It is important to control your blood pressure by taking blood pressure lowering pills and also by exercising regularly. Exercise seems to send a signal to relax the blood vessels thus lowering the blood pressure, which in turn prevents heart attacks.

3. COPD/emphysema:

Chronic obstructive pulmonary disease (COPD) or emphysema is mostly caused by chronic exposure to cigarette smoke from smoking. The earlier you can quit, the better your chances that your breathing will not be the limiting factor when you age. But it is also important to avoid exposure to other noxious gases, such as from welding and from exposure to pollution. This may involve a decision to move to a less polluted area. Or it might involve a job retraining. Those who are suffering from COPD can be helped to a certain extent by a portable oxygen tank with nasal prongs.

4. Stroke:

As mentioned before, quitting smoking, controlling high blood pressure and controlling blood sugar, if you suffer from diabetes have been shown to stabilize your blood vessels including the ones that supply your brain. The key is to prevent hardening of the arteries by a healthy lifestyle. Exercising and keeping your weight under a body mass index of 25.0 have been shown to be effective stroke prevention. Healthy nutrition as indicated above under “heart disease” is equally important for stroke prevention. Go green (eat more vegetables, consume more green smoothies), cut down grains, sugar and starchy foods and you will live longer without strokes and heart attacks. Remember, what’s good for your heart is good for your brain!

5. Unintentional accidents/injuries:

Wearing helmets when bicycling, wearing seat belts when driving in a car, avoiding risky behaviors are all measures that save lives. One factor stands out in all of this: if you drink too much, you run the risk of being involved in unintentional accidents or injuries. People may not like to hear this, but your brain lacks the natural inhibitory impulses when you are under the influence of alcohol, so you become more daring and you may not pay attention for the split second that could have prevented an injury or accident. People react very differently to alcohol. Some people feel inebriated after only ½ a glass of wine or beer whereas others can drink more before they make mistakes. The best is to be sober when you drive, ski, use power tools or walk in traffic. Even climbing ladders requires a clear mind!

Conclusion:

As the CDC said 20 to 40% of premature deaths (deaths that occurred before the age of 80) could have been prevented, if the above-mentioned recommendations were followed. Let me rephrase this: 180,000 to 360,000 premature deaths every year in the US before the age of 80 could have been prevented! Curative medicine cannot help with these statistics as a heart attack or stroke has happened when it has struck you. Cancer and end stage lung disease are similar conditions that you are suddenly faced with when they occur and unintentional accidents just seem to happen. This is where the importance of prevention can be seen, because these little baby steps every day are adding up to something formidable, a force to be reckoned with. Be part of the solution, think prevention!

Mold Allergies Often Overlooked

By | Allergies, Asthma, Health, Lung Disease, Prevention

In a recent news story extensive mold infestation was found in a house that had oriented strand boards (OSB) instead of plywood walls. The house also was tightly sealed trapping moisture, which contributed to the extensive mold problem.

Mold problems have been around for centuries, but only in the past few decades allergists  have pointed out to their patients how important it is to prevent this from happening.

In the following I will review a few typical scenarios that can lead to mold accumulation.

1. Mold from airtight house construction

The homeowner described in the link above is not the only case in the world that has a mold problem. Energy efficient homes are popular because they save energy costs; homeowners often also respond to gas companies, electric utility companies and government incentives to convert to airtight home construction.

In the 1980’s the construction industry introduced the cheaper OSB products to replace the more expensive plywood for wall construction. This is often the problem with newer house construction. However, older homes are not immune to mold development.

2. Roof leaks in older homes

Older homes that were built in the 1970’s may have plywood walls and have a bit of airflow from poorer wall construction, which would prevent mold formation. But roofs are older and do not always get replaced right away when a leak is detected. It may even take some time in areas where there is less precipitation before it is picked up during a particularly heavy rainstorm. Water that enters from a leaky roof can form a puddle on top of the ceiling where mold softens the drywall material until a leak in the ceiling causes water to drip down onto the floor. The mold spores multiply particularly well in wall-to-wall carpeting, but OSB material is also a good growth opportunity for molds due to the mini air spaces between the glued wood pieces. Plywood with its several tight layers is much more resistant to water penetration and mold growth.

3. Mold growth after hurricanes

After hurricane Sandy images of “black mold” were frequently shown in the media. The problem is that after 48 hours anything that was in contact with water produces mold. However, often with disasters like hurricanes there are evacuation orders and you cannot return to your home for several days. There may be further delay because there is a waiting period for insurers to assess the amount of damage, before you can clean all surfaces affected by mold.

The end is result often that expensive mold sanitation is needed or the person ends up moving away and the house is levelled before a new house can be built.

4. Effects of molds

People with preexisting allergies and asthma are more susceptible to the effects of molds. It leads to itchy eyes, wheezing, coughing, and exacerbation of asthma.

Here is a brief overview what the CDC is stating about mold. This site also explains that you can recognize a mold problem because of a musty smell or foul stench in the air and because of the appearance (discoloration of ceilings or walls, water damage).

You can clean hard surfaces with bleach water. Bleach kills molds, but it may have to be cleaned several times within a few days to get rid of the last spores. Whatever cannot be sanitized in this way must be removed or replaced.

5. Health concerns regarding molds

Ref. 1 reviewed the public concern about the toxic effects of molds. It noted that with the Internet and the popular press having exaggerated some of the connections of symptoms with mold allergies, the term “mold madness” has been coined (Ref.2). Despite the paranoia in the general public about toxins from molds, there is only a small percentage of the population that is sensitive to molds where IgE antibodies and IgG antibodies against molds can be determined through blood tests. These individuals often are also allergic to other environmental allergens like grass pollen and dust mites. The asthmatic reactions in sensitive people are not as severe as what peanut traces would do to peanut sensitive patients, but skin testing and blood test screening for specific IgE and IgG antibodies do often confirm that sensitive people indeed can have specific mold allergies. In the vast majority of people these tests are negative and correlations between mold infestations and allergic reactions could not be verified (Ref.1).

6. Fixing mold damage and dealing with allergies

It follows from this that you should remove any visible molds and fix whatever the cause was for its appearance. Carefully disinfect the areas with diluted bleach water (the CDC recommends 1 cup of bleach per 1 gallon of water) several times. Make sure the areas are dry and not musty otherwise you  have  work on improving ventilation. If you are not one of these hypersensitive persons, there is nothing to worry further. However, if you are hypersensitive an allergist should examine you. Common indoor molds that cause the so-called “immediate type hyper reactivity” are due to the mold species Aspergillum and Penicillium. Most outdoor molds that can cause problems for sensitive people are due to Alternaria and Cladosporium species. The latter would be the ones found in carpets after a leaky roof has caused problems. When the allergist has found specific allergies to one or several of the mold species, allergy shots may be prescribed that would have to be given weekly to the sensitive person who was found to have environmentally induced asthma. Often it takes several years for these desensitization shots to stop the affected person from reacting  to molds. In some cases patients need to stay on these shots life-long.

Conclusion

The key with regard to mold allergies is to prevent mold growth by being vigilant about detecting early problems with leaky roofs, walls and cleaning up water damage right away. When there is a musty tell- tale smell, investigate right away and remedy the problem. For most people this is the end of the story. However, a small percentage of very sensitive people need to consult with an allergist who should investigate whether or not these people would benefit from allergy injections.

In some rare cases the affected person may have to relocate to another house that is free from molds.

Pollution And Soaring Lung Cancer Rates

By | Allergies, Cancer, Hormones, Lung Disease, Obesity, Prevention

In early 1900 lung cancer was unheard of. This was before the cigarette industry started to mass-produce and market cigarettes.

However, ever since the arrival of the industrial revolution air quality has suffered. In China poor air quality has now reached such enormous values that the specialized cancer agency of the World Health Organization, the International Agency for Research on Cancer (IARC) has labeled poor air quality as one of the causes of lung cancer.

When you rank countries by average air pollution measurements, one sees that Europe, the US and South America overall have good ratings, whereas the Middle Eastern countries, China and India have poorer ratings.

However, when the pollution index of cities where the population is much denser than in the countries at large, are tabulated a much different picture emerges: Cities in Iran, India and Pakistan stand out as particularly bad followed by cities in China, Eastern Europe, Paris, London, Berlin, cities in California (the populous State), Chicago and New York.

Pollution does not stay local, but travels through the stratosphere around the globe. The result is that now 10 to 15% of lung cancer in the US occurs in patients who never smoked. This translates into 16,000 to 24,000 deaths annually of never-smokers in the US.

In certain cities such as Beijing the lung cancer rates have doubled in 9 years between 2002 and 2011. As this article shows lung cancer in never smokers can be caused from exposure to radon, to second-hand tobacco smoke, and other indoor air pollutants can also cause such cancers. But the outdoor air quality has been a problem ever since the industrial revolution, which started around Europe in the 1800’s and first part of the1900’s. In the latter half of the 1900’s much of the industrial wave has migrated to the Middle East, to India and China. But the air quality of the whole world has suffered as the jet stream and other air currents carry pollution in the stratosphere all around the globe.

Pollution And Soaring Lung Cancer Rates

Pollution And Soaring Lung Cancer Rates

History of pollution in various regions

1. In Germany’s  Ruhr district (“Ruhrgebiet”) in North Rhine-Westphalia, a highly populated industrial area, pollution reached a peak in the late 1950’s. From 1963 onward many of the coal mines, iron ore mines and other mineral mines closed down. 50 years ago the German Chancellor, Willy Brand was concerned about the environment and promised that blue skies would return to the Ruhr district again.  A special task force was initiated and maximally allowable limits were established for industries’ pollution emissions and enforced by the German government. Government and industry were co-operating in developing anti-pollution measures, which have cleared up a lot of the pollution since. With regard to car emissions lead free gasoline was introduced and carburetors ensured more complete burning of exhaust gases. This is now common and accepted anywhere except for diesel fume exhaust, which nobody wants to address despite proven carcinogenicity.

Now Germany is one of the leaders in green technology, which is also important for tourism.

2. England has its own legacy of pollution in soil and air from the industrial revolution. The soil of moorland, which soaked up acid rain for decades, is more acidy than lemon juice and it will take a long time despite industrial complexes having closed long time ago, before the soil quality will be returned to normal.

3. Hamilton in Ontario/Canada has had a longstanding pollution problem, which I witnessed from 1976 until my departure in 1978. It is well known that Stelco, the local steel plant downtown Hamilton is sending polluting emissions into the air. In 1976 a vising professor from Australia gave an interesting talk about a study that was done at that time regarding the risk of developing bronchogenic carcinoma (a synonym for lung cancer) in the immediate surroundings of the Stelco plant. He said that this was one of the first studies to show that the distance of people’s houses from the source of pollution mattered as that determined how concentrated the air pollution was (the closer the more polluted the air). This  affected cancer rates: they were much higher in the immediate surrounding of Stelco when compared to the average rate in the rest of Hamilton. This difference was very significant within a radius of 1 kilometer (= 0.62 miles) from the Stelco plant.

Just in May of 2013 the local cancer agency of Hamilton announced that the lung cancer rate in Hamilton was higher than elsewhere in Ontario because of a combination of poor air quality and of a higher percentage of people smoking. Then in August 2013 the city of Hamilton announced a new air pollution bylaw for stricter pollution measures to improve the air quality in the downtown area. It is just a pity that Hamiltonians had to wait until 2013 before the city approved an anti-pollution bylaw that could have been passed 50 years earlier like in Germany’s Ruhr district!

Lung cancer prevention by the authorities

As mentioned before up o15% of lung cancer is caused by environmental exposure. So, we ourselves can only prevent 85% of lung cancer by not smoking and not exposing ourselves to industrial emissions or to smoke from incense. However, in many cities around the world you will get exposed to air pollutants that are well above the safe limits, so the risk of getting lung cancer from just breathing the air there can be much higher than in rural areas where there is no industry.

Technologies to control air pollution are widely available. We need to exert pressure on politicians to show leadership around the world. Government regulations to lower emission rates need to be put into place and inspectors need to ensure the rules and regulations are adhered to. Without reducing emissions of cancer producing gases and chemicals right at the source (open burning of cuttings in orchards or burning cut trees), cutting emissions of cars, planes, ships, diesel cars, locomotives, electric generator plants etc. the air quality will not improve. Despite some costs involved industry, governments and individuals have to work together to make clean air happen.

The residents of those countries that have low pollution values will not benefit, if pollution continues to occur in other parts of the world as it just travels in the stratosphere around the globe until it arrives right here at home! We need an international pollution police. Satellites can be used to monitor where pollution occurs and this can be followed up through the local regulatory bodies with penalties and remedial actions.

What can I do personally to prevent lung cancer?

1.The most obvious step is to quit smoking and ask smokers who come to your place to smoke outside (not in your home).

2.Consider moving away from the city, if the air quality is unacceptable to a place where there is low air pollution.

3.Vitamin D3 has been shown to prevent colorectal cancer, but as there are vitamin D receptors found on the surface of various cells in tissue around the body including the lungs, many researchers feel that this vitamin in higher doses (2000 IU to 5000 IU) has probably a wider applicability in preventing cancers, even lung cancer.

4.Cutting out sugar and adopting a Mediterranean type diet is a prudent thing to do; also cutting down your calories to the maintenance you need (mildly ketogenic diet). If you bought body composition scales, it would display what your daily calorie consumption is and you should not exceed this, or else you’ll gain weight. An aging man who is overweight will experience hormone changes as fat is being metabolized and the enzyme aromatase contained in fatty tissue will turn male hormones (testosterone, DHT, androstenedione) into estrogen. Estrogen (particularly estradiol) is a known carcinogen that has been proven to cause breast cancer in women and prostate cancer in men. However lung cancer is also being promoted in women by estrogen as discussed in this link. In men one needs to remember that lung cells have estrogen receptors and there is concern in aging men with higher estradiol levels that this can promote cell divisions in existing lung cancer. So, it is important to maintain a normal body mass index between 21 and 24 (well below 25.0 and well above 18.5, which are the official accepted limits). This way there is no problem with insulin resistance (too high an insulin level), and other metabolic substances (cytokines, growth hormone like factors and tumor necrosis factor-alpha from body fat) that are cancer promoting.

5. If testosterone deficiency is present, which is common in older men, testosterone will have to be replaced with bioidentical hormones. It is a myth that testosterone would cause prostate cancer. Testosterone in males is necessary to maintain a normal metabolism including the immune system, which then can fight lung cancer and any other cancers.

6. Exercise and reducing beef consumption are also often mentioned in terms of preventing lung cancer.

7. Here are several recommendations from the LifeExtension Foundation that I found very useful in terms of lung cancer prevention. This link shows that antioxidant vitamins such as vitamin C, alpha tocopherol, the minerals selenium and zinc are also helping to reduce the lung cancer rate. Drinking green tea has also been shown to be effective in a dose-response curve manner (more tea protecting more from lung cancer). Vitamin B12 and folate have been shown to reduce abnormal bronchial cell growth in smokers as shown by repeat bronchoscopy studies.

8. Those who have been smokers in the past and those who have been around heavy smokers for more than 10 years in the past should consider having a preventative bronchoscopy done by a lung specialist (also called respirologist or pulmonologists). This way any suspicious areas with precancerous lesions can be biopsied during the procedure and attended to.

Hopeful research for new lung cancer treatments

Lung cancer is a disease that is best prevented. Once a person gets lung cancer, the prognosis is still very poor. However, cancer researchers are getting close to newer treatments involving genetically modified T-cells (killer cells) as was recently achieved for leukemia. Similar research is going on regarding ovarian cancer, melanoma, lung cancer and pancreatic cancer.

Conclusion

It is not acceptable to let pollution take its course , the way politicians around the globe have handled this in the past 6 decades with a few notable exceptions mentioned. We all suffer a higher risk of getting lung cancer, even if we have been life-long non-smokers. Right now up to 15% of lung cancer in most populations are of this type. However, in Beijing this number is already much higher. The technology is available; Germany has led the way in the Ruhr district in the 1960’s and beyond. In my opinion the G8 meetings should have this high on their agendas and send technological aid to all the regions that have higher than the average world pollution index under the mandate of a special UN commission. This should be supported by the major industrial players with the knowledge that they will prevent the death of millions of potential consumers down the road, which will on the long-term pay off the relatively minor investment of installing pollution controls, before lung cancer levels rise even more.
