submitted by: admin on 09/20/2013
Dr. Len and Nurse Vicki discuss the pros and cons for a routine colonoscopy for colon cancer screening.

Does Calcium Supplementation Increase Risk for Heart Attack and Stroke?
submitted by: admin on 09/20/2013
A meta-analysis of 29,000 people showed that calcium supplements increase the risk of heart attack by 30% and stroke by 20% in older women. On the other hand, calcium from food does not increase these risks. It would be necessary for 1000 women to take calcium supplementation with or without vitamin D to prevent 3 fractures and at the same time cause 6 additional...

Does Taking a Nap Make You Lazy?
submitted by: admin on 09/20/2013
Many of our best thinkers such as Einstein, Da Vinci, Tesla, and Churchill took afternoon power naps regularly. Progressive companies such as Newsweek, Google, and Time/Warner encourage afternoon naps because they have found there is increased productivity.
A Greek study found that men who took a 30 minute nap at least 3 times per week lowered...
Does Teflon Cause Osteoarthritis?
submitted by: admin on 09/20/2013
High blood levels of a chemical (PFOA) found when Teflon is heated to high temperatures was associated with a 40% increased risk for developing osteoarthritis. A second chemical also found in the contaminated water, PFOS, was associated with a 25% lower risk of osteoarthritis! It is hard to know when a chemical contamination will cause a health issue. PFOA has...

submitted by: admin on 09/20/2013
According to a study published in the Journal of Dairy Science in January of 2013, dairy cows fed 6 pounds of flaxseed per day have more nutritious milk.

Drugs for Depression and Heart Risks
submitted by: admin on 09/20/2013
Newer antidepressants are being promoted as better than the older ones. The bottom line is that when drugs go off patent, the drug companies have a need to convince MDs and the public that they should purchase their newer, more profitable products. There are problems with antidepressants that include increased risk of suicide, osteoporosis, and heart...
Fewer Mammograms Needed for Low-Risk Women
submitted by: admin on 06/18/2016
Less frequent mammograms for wonem at low risk for breast cancer can be a cost effective way of saving lives. Women with no family history of breast cancer, no previous biopsy and breasts that are not dense need far fewer mammograms than women with these risk factors. For women under the age of 50 without these three risk factors, mammograms are not worthwhile....
H. Pylori Increases Risk for Type 2 Diabetes
submitted by: admin on 09/22/2013
According to a January 2012 article published in Diabetes Care, people infected with H. pylori are more than twice as likely to develop type 2 diabetes than those without the infection. Clearly, this is an association, not a cause because although 97% of those testing positive for the microbe and developing type 2 diabetes, 91% who did not develop type 2 diabetes....
HDL Level and Risk of MI Questioned
submitted by: admin on 02/19/2015
Treatment to increase HDL cholesterol has been viewed as useful, but new data published in the journal Lancet in May of 2012, suggests that there's no value in doing so to prevent heart attacks. It could be that HDL is a marker for increased risk for heart attack, much like the PSA is a marker for prostate cancer. This does not mean that statin...
Heart Attack Prevention

Heart Monitoring During Anesthesia
submitted by: admin on 09/23/2013
Only 35% of anesthesiologists monitor cardiac output during surgery. For high risk surgeries this is dangerous as it is critical to know if adequate oxygenation of tissues is being accomplished. It is critical to know the level of hemoglobin in our red cells, as that determines how much oxygen carrying capacity we have. It is also important to know that enough...
High Calcium Intake Doubles Risk for Heart Disease
submitted by: admin on 09/24/2013
Calcium intake above 1400 mg per day is associated with doubling the risk of dying from a heart attack in both men and women. There are many studies showing that in women with osteoporosis who take large doses of calcium are at risk for both heart attacks and stroke.
Although it may be logical to try and replace the lost calcium in bone in osteoporosis...
High Dose Statins Associated with Increased Risk of Diabetes
submitted by: admin on 09/24/2013
A meta-analysis showed that high dose statin therapy as primary prevention caused an increased risk for type 2 diabetes. The article published in JAMA goes on to say that treatment of 32,000 non-diabetics with 5 years high dose statin treatment caused 149 more cases of type 2 diabetes, but 416 fewer cardiovascular events.This is a very misleading journal article...
How Chocolate Reduces Risk for Heart Attacks and Strokes
submitted by: admin on 10/22/2018
Scientists from LSU Medical Center reported at the 247th National Meeting & Exposition on how the flora in the intestinal tract digest chocolate and convert its large, poorly absorbed, polyphenols that protect the heart and brain from inflammation, into smaller, more easily absorbed antioxidants. They recommend building up the gut microbes that accomplish...
How to Assess Your Blood Pressure
submitted by: admin on 02/19/2015
The best way to assess your blood pressure is to take multiple home readings. This is more accurate than taking blood pressures in the doctor's office because of the "white coat syndrome."

Importance of Sleep
submitted by: admin on 10/09/2013
Lack of sleep leads to chronic inflammation that puts us at risk for many chronic diseases that are discussed. It also has profound effects on our stress hormones as well as insulin and leptin. We need 7-8 hours of sleep.
Introduction for Managing Heart Disease
submitted by: admin on 11/23/2024
Arteriosclerotic heart disease is defined by reduced blood flow caused by cholesterol plaques, with or without blood clots, in one or more blood vessels of the heart. This situation can lead to insufficient nutrient delivery to the downstream tissues that can cause these very important complications.
Congestive heart failure...
Is Getting Cancer Just Bad Luck?
submitted by: admin on 01/22/2015
Reseachers from John Hopkins Cancer created a statistical model measuring the proportion of cancer incidence caused by random mutations during stem cell division; this was published in the journal, Science in January of 2015. They concluded that 2/3 of cancers can be explained by "bad luck." What they really determined was an association rather than...
