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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
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.
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 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.
