A new UCLA study shows that patients who choose to use mail-order pharmacies demonstrated higher rates of adherence to their prescribed medications than those who used traditional pharmacies. Nearly 85% of mail-order pharmacy patrons took their medications as prescribed by their doctor, compared to 77% of traditional pharmacy patrons. As well, more people who used mail-order pharmacies chose to do so because of financial incentives (mail-order pharmacies are often able to offer very competitive prices, compared to traditional pharmacies). The researchers studied people with chronic diseases – diabetes, high cholesterol and high blood pressure – which is important since management often requires lifelong pharmacotherapy. “Our findings indicate that mail-order pharmacies streamline the medication acquisition process, which is associated with better medication adherence,” said lead researcher, Dr. O. Kenrik Duru. [via Yahoo! News]

We know that a diet high in sugar can contribute to obesity, which in turn can cause hypertension. But now scientists have discovered that sugar, especially fructose, can have a direct bearing on one’s blood pressure. The connection? Uric acid. If you have gout, you probably know a bit about uric acid. It’s the substance that builds up in joints during a painful gout attack. But it seems that uric acid can also inhibit the production of nitric oxide, a compound that is essential for keeping our blood vessels flexible – when our blood vessels are less flexible and compliant, hypertension sets in. Researchers tested this theory by placing subjects on a high-fructose diet and giving some of them allopurinol, a drug commonly used to reduce uric acid levels in patients with gout. Those who weren’t on the drug had a 6 mm Hg-increase in systolic blood pressure and a 3 mm Hg-increase in diastolic pressure, compared to those on allopurinol. These findings were presented at the American Heart Association’s High Blood Pressure Research Conference in Chicago. [via ABC News]

I’ve had quite a number of patients come in lately for general check-ups because they will soon be losing their job-sponsored health insurance coverage. I commend them for coming in. After all, late is sometimes better than never. Therefore, for today’s post I’d like to share some tips on things you should consider when your coverage is about to end.

1. Get an annual physical exam, including a skin check for possible skin cancers. It could get pricey should you need a biopsy and subsequent treatment.

2. Get your routine tests done. Those over 50 years of age should get a colonoscopy every 10 years. Women over 40 should have an annual mammogram. Women should also get annual pap smears.

3. Know your numbers: check your blood pressure, cholesterol, basic chemistries, urine analysis.

4. If you’re a smoker, speak to your doctor about ways to help you quit. Quitting smoking greatly reduces your risk of cancers and cardiovascular disease.

5. Ask your doctor about your risk for osteoporosis. In general all women over the age of 65 should get a DEXA bone densitometry scan at least once.

6. Speak to your doctor about weight loss. Keeping your weight under control can reduce your risk of diabetes, heart disease, high blood pressure, osteoarthritis, and high cholesterol, among a multitude of other diseases.

7. Get a flu shot and update your vaccinations. For adults these may include hepatitis A and B, herpes zoster (shingles), Tdap, chickenpox. If you are aged 65 or older you should have a pneumovax vaccination as well.

8. Refill your medications. Depending on the medicine, it may be possible for your physician to give you more refills. Similarly, if you are diabetic make sure your doctor gives you plenty of refills for glucose testing supplies.

*There are always exceptions to the rules. These are only general guidelines. Speak to your doctor to find out what is appropriate for you.

The American Chemical Society reports new evidence that humans can make their own salicylic acid (SA), the compound largely responsible for aspirin’s effects on pain, fever, and inflammation. SA is a naturally occurring substance that can be obtained directly from eating fruits and vegetables. Researchers have previously shown that vegetarians have much higher levels of SA in their bodies (sometimes as high as in those who take low doses of aspirin). Now, the same research group claims that new evidence suggest that our bodies can actually manufacture SA from compounds we consume in our diet. Could SA be one of the chemicals responsible for the health benefits of a vegetarian diet? Numerous studies have shown that vegetarians seem to have a lower risk of obesity, coronary heart disease (which can cause heart attacks), high blood pressure, and diabetes.

Regular aerobic exercise has been extensively studied and is known to have long-term cardiac benefits. However, did you know that listening to your favorite tune can dilate your blood vessels the same way exercise or drugs used to treat high blood pressure and cholesterol do? Researchers have shown that when people listen to music that makes them feel good (you pick the song) the effect of blood vessel dilation can last for almost an hour afterwords. Blood vessels that are able to react by dilating are termed as more “elastic.” More elastic vessels decrease the risk of atherosclerosis and blood clot formation that can lead to stroke and heart attacks.

Researchers at Johns Hopkins University have discovered an enzyme in blood vessels which produces small amounts of hydrogen sulphide, the gas responsible for the smell of rotten eggs and flatulence. The discovery is notable for the fact that the gas signals blood vessels to relax, dilate, and thereby lower blood pressure. Another gas that functions in a similar manner is nitric oxide, which is often used in the treatment of heart disease. Scientists are hoping to base future blood pressure medications on the discovery of this gas.
