Fungus Toenails – Deformed Toenails

Fungus infections cause less than five percent of deformed nails. Drying of skin and skin conditions such as psoriasis are more common causes. The part of nails that you see is dead. Living nails are located underneath the skin at their base.

Guidelines for COVID-19 Fully Vaccinated People

The U.S. Centers for Disease Control and Prevention (CDC) released recommendations for fully vaccinated people who are two weeks past their second injection of the Moderna or Pfizer COVID-19 vaccines, or have had the one-dose Johnson & Johnson vaccine. As of March 8, 2021, more than 31 million people (9.4 percent of the U.S. population) had completed these vaccines.

Reduce Inflammation and Clotting to Prevent Heart Attacks

Heart attacks and strokes cause 50 percent of the deaths in North America today, yet many people are not adopting the lifestyle changes needed to prevent the factors that cause them: inflammation and clotting. A new study from the University of Michigan shows how important inflammation is as a cause of heart attacks and strokes.

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.

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.

How Low Should Your Cholesterol Be?

Having high blood levels of the bad LDL cholesterol (>100 mg/dL) is associated with increased risk for heart attacks and premature death, and is the single most important predictor of forming plaques in your arteries. Many experts recommend lowering elevated LDL levels to 70 mg/dL in people who are at increased risk for heart attacks.

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.

Best Diet to Prevent and Treat Diabetes

More than 30 million adults in North America suffer from diabetes and another 85 million have pre-diabetes that is likely to become full-blown diabetes within five years. Research papers published this month suggest that people who are diabetic or likely to become diabetic should eat a very large amount of plant fiber and restrict animal products, particularly red meat and processed meats.

Atrial Fibrillation in Endurance Athletes

Medical researchers agree that exercising into old age helps to prevent heart attacks, strokes and cancers and prolongs lives, but one report shows that sometimes competing in endurance sports may cause atrial fibrillation.

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.

Long COVID-19 Syndrome

Most people who develop COVID-19 recover in 2-6 weeks, but between 10 and 70 percent of recovered COVID-19 patients develop “Long COVID-19 Syndrome,” suffering at least one symptom for many weeks or months after their initial infection.

Aging and Risk for Dementia

Dementia means loss of brain function, and your chance of having dementia increases with age. Doctors can now predict increased risk for developing dementia by ordering an MRI which can show decreased volume of grey matter in the brain.

Arthroscopic Knee Surgery is Usually Useless

I have said repeatedly that surgery to trim attached cartilage in the knee is usually worthless. I have seen many patients who have had cartilage removed by surgeons for an average charge of $5000, and then they must have a knee replacement several years later.

Two New COVID-19 Vaccines Coming Soon

The Pfizer\BioNTech and Moderna messenger RNA (mRNA) vaccines are already available for some people. They require two injections and look better all the time, with very few serious reactions so far and good antibody response for prevention of COVID-19. Two more vaccines appear ready to be available soon for public immunization.

Lifestyle and Drugs to Prevent and Treat Osteoporosis

On April 9, 2019, the U.S. Food and Drug Administration approved a new osteoporosis drug called Evenity. Bones are constantly changed by bone cells called osteoblasts that grow new bone and osteoclasts that remove old bone cells. Evenity is a monoclonal antibody that blocks the effects of the protein sclerostin that encourages the growth of osteoclasts that remove old bone cells.

Metabolic Syndrome Predicts Heart Attacks and Diabetes

A huge study from Korea confirms that people with Metabolic Syndrome are at increased risk for heart attacks, and that when they correct some or all of the components of Metabolic Syndrome, their risk for a heart attack goes down dramatically.

Knee Pain: Treat with Lifestyle Changes

A review of 47 .studies on 22,037 patients with knee osteoarthritis treated for at least 12 months showed no clear difference in controlling long-term pain between medications and placebos. With the exception of immune suppressants that have lots of serious side effects, medications and health supplements do not prevent progressive damage to joints and are used only to help lessen pain.

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.

Daily Aspirin May Not Save Lives

Aspirin has been shown to help prevent a second heart attack in people who have already had a heart attack. However, aspirin also causes bleeding that can kill a person, so researchers wanted to find out if the heart-attack-preventing effects of aspirin would be offset by the complications of bleeding that aspirin can cause.

Blood Pressure During and After Exercise

Your blood pressure usually rises as soon as you start to exercise and drops a little bit while you exercise at the same intensity. However, as you continue to increase the intensity of exercise, your blood pressure usually rises higher and higher.

Strengthen Bones with Weight Training

Your bones weaken progressively after age 30, and between ages 35 and 50, about 28 percent of North American men and women suffer from bone weakening called osteopenia. Just one year of lifting weights can strengthen the bones enough to help protect people from fractures.

What Do Blood Cholesterol Levels Mean?

Having a high (>100 mg/dL) bad LDL cholesterol or a low (<40) good HDL cholesterol has long been associated with increased risk for heart attacks. However, new studies show that you can form plaques and be at risk for a heart attack even if your bad LDL cholesterol is as low as 50.

Running and Walking May Be Good for Your Back

People who run or walk regularly have healthier and stronger spinal discs than non-exercisers do (Scientific Reports 7, April 19, 2017). This is very reassuring because some doctors tell patients with back pain not to run because they think that the jarring of the foot striking the ground will damage discs and injure backs,.

Low Vitamin D Increases COVID-19 Risks

If your vitamin D level is below 30 ng/mL, you are at increased risk for contracting COVID-19. A review of 40 studies showed that adequate vitamin D reduced the frequency and severity of COVID-19 infections and hospital admissions, and lowered the death rate

Large Doses of Vitamin D Can Be Harmful

Lack of vitamin D can cause weak bones that break easily, bone pain, and muscle weakness, and may increase risk for diabetes, high blood pressure, certain cancers, nerve damage and autoimmune conditions such as multiple sclerosis. However, taking very high doses (>3000 IU/day) of vitamin D can harm you.

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.

Lifestyle Changes to Reduce Joint Pain

Eighty percent of North Americans have X-ray evidence of osteoarthritis by age 65, and 60 percent have significant joint pain. Researchers at Surrey University in England reviewed 68 studies on the effects of diet on osteoarthritis and found that osteoarthritis is associated with everything that increases inflammation, and that the joint pain can be reduced by everything associated with the control of inflammation.

Second Dose of COVID-19 Vaccine Can Be Delayed if Necessary

Many people are worried that they may not receive their second dose of the vaccine on schedule because of delayed deliveries of the vaccine, or because of suggestions that the scheduled second doses of the vaccines should be given as a first dose to others so that more people can be immunized.

High Blood Pressure and Colon Bacteria

The CARDIA Study shows that having certain types of bacteria in your colon is associated with having high blood pressure, and that you can lower blood pressure by improving the proportion of healthful to unhealthful bacteria in your colon. Lifestyle changes may be more important than drugs in treating high blood pressure.

Yogurt or Cheese Instead of Milk Reduces Heart Attack Risk

A recent Danish study followed 54,903 healthy men and women, 50-64 years old, for 16 years. Those who ate primarily fermented dairy products such as cheese and yogurt were significantly less likely to suffer heart attacks than those who drank milk.
