Dementia May Be Preventable

The American Heart Association has published a scientific statement on “Harnessing Healthy Behaviors to Prevent Dementia” (Stroke, Mar 15, 2021:52(6A);52:e295–e308). They report that dementia is associated with the following modifiable risk factors: depression, all heart attack risk factors, high blood pressure, diabetes, obesity, high cholesterol, physical inactivity, an inflammatory diet, smoking, social isolation, excessive alcohol use, sleep disorders and hearing loss.

Arthritis and Colon Bacteria

A study of 1,388 women with hand arthritis, average age 61, showed that they had higher levels in their colons of the bacteria Bilophila and Desulfovibrio that try to invade their colon cells, as well as a lower level of the genus Roseburia that do not invade colon cells. An anti-inflammatory lifestyle has been shown to help grow healthful bacteria in your colon, which can help to treat arthritis.

Treating Type II Diabetes and High Blood Pressure with Diet

Type II Diabetes shortens lives by causing high blood pressure, strokes and heart attacks. Diabetics in the DIRECT study in Scotland, who followed a strict 800-calorie-per-day diet and lost a lot of weight, were also able to lower their high blood pressure.

Routine CT Scans Can Increase Cancer Risk

More than 80 million CT scans are done in the U.S. each year to help diagnose many medical conditions. In 2007, the National Cancer Institute predicted that 29,000 future cancer cases could be linked to the CT scans performed in the U.S. in that year alone, and doctors have ordered more CT scans every year since then.

High-Plant, Low-Salt Diet to Lower Blood Pressure

High blood pressure affects 108 million adults, increasing risk for heart attacks, the leading cause of death in the United States. A Harvard study of 412 adults found that a low-salt version of the DASH diet dramatically lowered both high blood pressure and markers of heart muscle damage in just four weeks

Jim Allison’s Nobel Prize: Toward a Cure for Cancer

In August 2015, the world learned that former U.S. president Jimmy Carter’s melanoma skin cancer had spread to his liver and his brain. Patients with melanoma that had spread through their bodies were expected to die from their disease, but doctors radiated Carter's tumors and then gave him Keytruda, a check point inhibitor. Three months later, there was no evidence of cancer in his 91-year old body.

Exercise to Treat Arthritis

If you have joint pains, you should still keep moving. There is increasing evidence that exercise can help to treat and prevent osteoarthritis of the hips and knees and even relieve some of the pain following hip and knee replacements Inactivity worsens arthritis by preventing joints from healing.

Risk Factors for Dementia and Heart Attacks Start Early in Life

Researchers in Finland followed 3,596 children (3-18) for 31 years to see whether cardiovascular risk factors in childhood and adolescence were associated with cognitive performance later in life. Cognitive testing was performed in 2,026 of the participants at 34-49 years of age, and the researchers found that early heart attack risk factors were also major risk factors for reduced mental function.

Many Common Drugs Can Raise Blood Pressure

High blood pressure markedly increases risk for heart attacks and strokes. A study of 10,676 adults, average age 56, found that 47.2 percent had high blood pressure, and one in five of the subjects who had high blood pressure (>130/80) took medicines that can raise blood pressure.

Muscle Pain While Taking Statins for High Cholesterol

More than one hundred million North Americans have taken statin drugs that help to save lives by lowering cholesterol and preventing heart attacks. Ten to 20 percent of people who take statins have been reported to have suffered muscle pain, but a recent study from the UK claims to show that statins are no more likely than a placebo to cause muscle pain.

COVID-19 Update – Vaccines Are Very Effective

An Israeli study followed 596,618 people who were newly vaccinated with the Pfizer-BioNTech mRNA vaccine during a six-week period from December 20, 2020, to February 1, 2021, and a matched group of the same number of unvaccinated controls. The researchers found that the vaccine offered a high degree of protection, similar to the results shown in the clinical trials.

Excess Belly Fat Increases Heart Attack Risk Even If You Are Not Overweight

The American Heart Association (AHA) reports that a high waist circumference among individuals with normal weight appears to be a more reliable predictor of risk for heart attacks than just being overweight. The AHA recommends using the ratio of waist circumference to body height or the waist-to-hip ratio to warn about increased heart attack risk.

Lack of Sleep Linked to Risk for Dementia

Researchers in the Whitehall Study followed 7959 British men and women for 30 years, with data on their sleep habits collected at ages 50, 60 and 70. They found that those who slept six hours or less per night had a 30 percent increased risk for dementia, compared with those who slept seven hours or more.

Treatable Risk Factors for Severe COVID-19

Don't believe the claims made for nutritional products that are supposed to boost your immunity and protect you from infections, unless you suffer from a specific medical condition or deficiency that can be corrected by that product. The current evidence shows that you are at increased risk for infection with, and severity of, COVID-19 if you have a medical condition that interferes with your immune system such as diabetes, high blood pressure, obesity, heart disease, liver disease, kidney disease, and so forth.

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.

COVID-19 Precautions May Affect Other Respiratory Infections in the Future

The U.S. Centers for Disease Control and Prevention (CDC) reports that we may need to continue social distancing and hand washing for years to come. The significant reduction in non-COVID-19 respiratory infections this year could decrease the number of people who are immune to other respiratory viruses, and increase the frequency and severity of other respiratory infections in the future.

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.

Prostate Cancer and Heart Attacks Share Lifestyle Factors

A study of 90,494 U.S. veterans with prostate cancer found that more than half suffered from uncontrolled risk factors for heart attacks. Men who suffer from prostate cancer have a very high rate of heart attack risk factors and heart disease.

Johnson & Johnson’s COVID-19 Vaccine Approved

The Johnson & Johnson COVID-19 vaccine has been approved for emergency use in the U.S., and millions of doses are now being shipped. We already have mass immunizations underway with the Pfizer and Moderna vaccines, which look better and better as we keep getting new reports of their benefits and minimal side effects.

Gut Bacteria and Colon Cancer Risk Factors

A review of 45 prospective studies found that risk for suffering colon cancer is increased by drinking alcohol and eating red meat, and decreased by eating more fiber and yogurt. More than 1.3 million North Americans have had colorectal cancer, a disease associated with lifestyle factors that cause bad bacteria to thrive in your colon.

Omega-3’s from Fish and Plants Help to Prevent Heart Attacks

People who had higher blood levels of omega-3 fatty acids at the time of a heart attack were far less likely to die or to have repeat heart attacks within three years, compared to those who had lower levels. The sources of omega-3s in the 944 heart attack patients in this study included both fish and plants.

People Who Have Had COVID-19 Are Protected for Three Months, Probably More

Two studies suggest that you can get long-term immunity after being infected with COVID-19. People who previously had COVID-19 have high protective antibody titers for at least three months, and at six months still had persistent parts of the COVID-19 virus in their intestines that continued to cause high protection antibodies.

Messenger RNA May Help to Beat Cancer

The two currently-approved COVID-19 vaccines use a technique called messenger RNA (mRNA) that could lead to cures for cancer and many other diseases.

Johnson & Johnson’s COVID-19 Vaccine is Coming

The soon to be approved vaccine for COVID-19 from Johnson & Johnson requires just one injection, instead of the two required for the previously-approved vaccines from Pfizer and Moderna. The J&J vaccine can be stored with ordinary refrigeration and does not need the extremely cold storage required for the Pfizer or Moderna vaccines.

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.

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.

High Blood Pressure Increases Risk for Dementia

A study of 7063 people, average age 58.9 years, found that those who had high blood pressure had significantly lower memory and recognition test scores than the people with normal blood pressure. In four years of follow-up, they found that better control of high blood pressure during the study period helped to reduce the loss of mental function.

Many Cases of COVID-19 Come from People with No Symptoms

People with no symptoms transmit more than half of all cases of COVID-19, according to a model developed by researchers at the Centers for Disease Control and Prevention. This reinforces the importance of following the CDC's basic guidelines: wear a mask, wash your hands, and stay socially distant.

Safety of the Messenger RNA Vaccines for COVID-19 (Pfizer and Moderna)

Results from clinical trials of the Pfizer-BioNTech and the Moderna COVID-19 vaccines showed about 95 percent effectiveness in preventing COVID-19 infections, and they were given Emergency Use Authorizations (EUA) by the U.S. Food and Drug Administration (FDA) on December 13 and December 20, 2020. The U.S. Centers for Disease Control and Prevention (CDC) says...

How Pre-Diabetes Increases Risk for Dementia

One of the definitions of pre-diabetes is a high rise in blood sugar after meals, and a recent study suggests that many cases of dementia are linked to these high rises in blood sugar. This study of 3889 adults found that people who suffer from loss of mental function and dementia have much higher levels of Advanced Glycation Endproducts (AGEs) in their skin.
