Pfizer Vaccine 90 Percent Effective in Early Data

Pfizer and its German partner, BioNTech, have announced that their COVID-19 vaccine appears to be more than 90 percent effective against the disease. Early data from their 44,000-person trial analyzed the first 94 cases of symptomatic COVID-19 among the participants who received either the two-dose vaccine or a saline placebo.

Exercise Should Be Part of the Treatment for Cancer

A study from the Karolinska Institutet in Sweden shows that repeated bouts of exercise slow the growth of, and help to prevent recurrences of, cancers. The authors showed, in both mice and humans, that exercising muscles release into the bloodstream chemicals that increase production of CD8+ cells that an individual's own immune system uses to kill cancer cells.

Colon Cancer Risk and Neu5Gc Antibodies

Researchers have suggested a method to measure antibodies in humans after they eat the foods that contain Neu5Gc (BMC Medicine, Oct 23, 2020;18(262)). The more meat and dairy a person eats, the higher the rise in antibodies against Neu5Gc.

Herd Immunity With Vaccines

The only way that the pandemic will end is when a sufficient percentage of people become immune to COVID-19, most by being vaccinated plus a lesser number of people who have been infected with the virus and recovered. This is called herd immunity. Researchers tell us that in the U.S., the pandemic will not end until about 40 to 70 percent of the population is immune.

Drugs Given to President Trump for COVID-19

As reported by the White House medical team, the drugs given to President Trump to treat COVID-19 included Regeneron's antibody cocktail (monoclonal antibodies), Gilead Sciences' remdesivir (brand name Veklury), and dexamethasone.

Colon Cancer, a Preventable Disease?

One in 20 North Americans can expect to develop colon cancer, with more than 100,000 new cases each year. A recent review of 80 studies found that most cases of colon cancer are linked to poor lifestyle choices.

Do Not Overdose on Vitamin D

You cannot be poisoned by vitamin D through sun exposure or diet alone, but vitamin D poisoning can occur when people take high-dose supplements for an extended time. Excess vitamin D can cause blood calcium levels to rise and after several months of having high blood calcium levels and having no symptoms at all, you can develop kidney failure and not even know it.

Get Your Flu Shot During the COVID-19 Pandemic

A flu shot will help to protect you from this year's flu viruses. A flu shot will not protect you from developing COVID-19, but the odds of severe disease, ventilatory support requirement, and death were reduced in people who had a recent trivalent flu vaccine.

Inhaled COVID-19 Vaccine Being Tested

Oxford University researchers have started testing inhaled versions of their COVID-19 vaccines compared to those given by intramuscular injection (Associated Press, Sept 14, 2020). An inhaled vaccine could be more effective than those given by injection because it may cause a stronger local immunity in the throat and nose, which are the primary entryways for the virus.

Low Vitamin D Can Increase Risk for and Severity of COVID-19

Vitamin D deficiency increases risk for becoming infected with COVID-19, and for complications and death from the disease. A study of 500 patients showed that those who had low blood levels of hydroxy vitamin D were twice as likely as those with normal levels to develop COVID-19.

How Would I Treat Myself If I Got COVID-19?

If I had COVID-19 and was not very sick, I do not know if I would take anything. Today there are no drugs or treatments proven to prevent or cure COVID-19, and the U.S. Food and Drug Administration (FDA) has not licensed any treatment specifically for the virus.

Avoid Ultra Violet Lamps for COVID-19

Don't put your faith in the many advertisements for ultraviolet light machines making claims that they destroy SARS-CoV-2, the virus that causes COVID-19. They have not been shown to be effective, and UV rays strong enough to kill a virus may also damage your skin and eyes.

What We Have Learned So Far from Eight Months of the COVID-19 Pandemic

Infection with COVID-19 comes primarily from breathing air in indoor spaces where people with the coronavirus have been, and the more virus you breathe in, the more likely you are to become infected.

Making Vaccines to Stop the COVID-19 Pandemic

The only way that scientists are going to end this current pandemic is to develop vaccines and immunize enough people to reach immunity in about 40 percent of the population from the vaccines or by having been infected with the disease.

High Blood Sugar Increases Risk for Complications in COVID-19

A study from Wuhan, China showed that non-diabetic COVID-19 patients with high blood sugar levels on admission to the hospital were more than twice as likely to die within a month and four times more likely to suffer the most serious complications caused by that disease.

Brain Health Supplements Are a Waste of Money

The Global Council on Brain Health (GCBH) reports that supplements sold to improve your memory and to prevent dementia are a waste of your money. There is no good evidence that any over-the-counter or prescription supplement can delay the onset of dementia, or prevent, treat or reverse Alzheimer’s disease.

Some Cases of Dementia Have Effective Treatments

More than six million North Americans suffer from dementia, which affects three percent of people age 65-74, 17 percent of age 75-84, and 32 percent of those age 85 and older. Anything that damages brain cells can cause dementia and many of the causes are treatable.

Protecting Yourself from COVID-19

As businesses and activities are re-opening, many people have decided to relax their precautions to avoid infection with COVID-19. If you are a person who is at high risk for complications from this virus, I believe that you should continue to be on guard.

Healthful Lifestyles to Prevent Cancer

The National Health and Nutrition Examination Survey found that nearly 70 percent of U.S. adults age 20 years or older are overweight or obese. Being overweight markedly increases cancer risk.

History of Chronic Fatigue Syndrome

When a person becomes extraordinarily tired to the point where he or she can’t get through the day, doctors should do an extensive evaluation to try to find the cause. They check for an infection, a hidden cancer, impaired immunity, poisons, an autoimmune disease, lack of minerals, hormone imbalance, and so forth.

Night-Time Leg Cramps

Up to 60 percent of North American adults suffer from night-time leg cramps, a sudden painful contraction usually of the calf muscles that can last from a few seconds up to 10 minutes or more. Doctors do not know what causes most cases of leg cramps, but usually they are not caused by dehydration or lack of minerals.

Sunscreens and Sun Protection

Sunscreens help to prevent sunburns and skin cancers because they actually block the ultraviolet rays of the sun that damage the skin. However, some sunscreens are safe, while others may not be safe.

Recent News on COVID-19

CAUTION: The news media often reports on articles from the websites of scientific journals that have not yet been peer reviewed by other doctors. It has become common practice to "pre-publish" studies or press releases online before they have been fully reviewed, and many of these reports are sent out by companies with a lot of money at stake.

Potential Treatments for COVID-19

As of today doctors have no proven effective treatment for COVID-19. However, many studies are being conducted all over the world. Here are some of the reported studies.

Getting Frequent Infections Can Precede Cancer Diagnosis

People who develop frequent infections are at increased risk for developing cancer later on. Japanese researchers checked 2,354 patients suffering from malignant cancers and found that compared to those who did not develop cancer, cancer sufferers were at significantly increased risk for suffering infections such as influenza, pneumonia, hepatitis, or gastroenteritis in the six years before they were diagnosed with cancer

A First Vaccine for COVID-19

Oxford University in England has developed a vaccine and will start trials on more than 6,000 people on Thursday, April 30, 2020, to see if their new vaccine is safe and effective.

Why Obesity Increases Risk of Death from COVID-19 or Influenza

A review of 4,103 patients found that obesity and its resultant inflammation, heart disease and diabetes are the most common conditions found in patients requiring hospitalization with COVID-19.

Potential Drugs, Treatments and Vaccines for COVID-19

We have no drugs yet proven to prevent or treat COVID-19, although some drugs appear  promising, as do transfusions of blood donated by people who have recovered and are now immune. The virus is spread from one person to another; it has not been shown to be spread from animals or food.

Latest Advice on the COVID-19 Pandemic

Federal guidelines now require most Americans to avoid non-essential travel, non-essential work, eating at bars and restaurants, and gathering in groups of more than 10, at least through April 30, 2020. Many states and local governments have stricter directives that take precedence over the federal guidelines.

The Current Coronavirus Pandemic – Updated

The World Health Organization (WHO) gave the new coronavirus the name "COVID-19" on February 11, 2020, and declared it a pandemic on March 10, 2020. COVID-19 is not more severe than many flu viruses. However, it is incredibly contagious.
