UPDATE

Radiation Therapy Poses

Future Heart Risk

In “Our Irradiated Lives” (May), we learned that medical scanning, especially CT scans, is one of the biggest sources of low-level radiation.

In addition to its use in diagnostics, radiation is also used therapeutically in the treatment of cancer. And while such treatment can be lifesaving, it can cause side effects decades after someone is declared cancer-free.

Cleveland Clinic researchers have found that receiving chest radiation results in a twofold increase in the risk of dying after heart surgery.

The study group compared 173 people who had undergone radiation therapy an average of 18 years before surgery with 305 other heart patients. The death risk in the first 30 days following surgery were the same for both groups. However, after an average followup time on nearly eight years, 55% of the radiation group died as opposed to 28% of the patients who hadn’t undergone radiation therapy.

Results were published in the journal Circulation.

CoQ10 May Aid Heart Failure,

Boost Muscle Power

A vitamin-like nutrient called CoQ10 has reduced death rates in heart failure patients and increased performance among athletes, according to two separate studies.

An investigation led by Copenhagen University Hospital in Denmark divided 420 Asian and European patients into two groups. One received 100 mg of CoQ10 (coenzyme Q10), an antioxidant that plays a key role in cellular energy production; the other received a placebo. After two years 25% of those in the placebo group had a major cardiovascular event, such as a heart attack or stroke, compared with 14% in the CoQ10 group.

Results were presented to the European Society of Cardiology.

In the other study, 100 young German athletes—53 men and 47 women—took either a placebo or ubiquinol, a form of CoQ10 more readily usable within the body. All the athletes then underwent muscle output testing while riding exercise bikes.

Compared with those in the control group, participants taking ubiquinol increased their muscular power by more than 2.5%.“Older athletes and ‘weekend warriors’ might profit even more from CoQ10 supplementation,” wrote the research group in the Journal of the International Society of Sports Nutrition.

MSM May Ease Aching Muscles

One of the less attractive aspects of vigorous exercise is the resulting muscular soreness. But a supplement called MSM may help alleviate workout-related discomfort.

Florida researchers gave 24 trained young men either MSM or a placebo after the participants had performed leg extensions until they couldn’t do another rep. Two hours and 48 hours after the workout, the study team assessed the men’s levels of pain and inflammation.

Taking MSM “resulted in significantly less pain and discomfort” as well as reduction in levels of IL-6, a key inflammation marker, according to study results published in The Journal of the Federation of American Societies for Experimental Biology.

MSM (methylsulfonylmethane), a source of biologically active sulfur, appears to inhibit the transmission of pain signals. It has also been found to promote blood flow, ease spasms and support tissue detoxification.

The sulfur in MSM is used by the body to create collagen, a tough, flexible protein mesh found in joints. It is often recommended by alternative practitioners for arthritis, especially when combined with the joint nutrients glucosamine and chondrotin. It is also used to provide relief from disorders such as fibromyalgia, carpal tunnel syndrome, bursitis, chronic headaches and other forms of pain.

Collagen is a key skin component. Some people who use MSM have reported less wrinkling and a more youthful appearence as well as faster, thicker hair growth and harder, stronger nails. Some practitioners have even found that scleroderma, a condition marked by thick, hard skin, responds well to MSM.

WORD

Squamous

Squamous cells are flat cells found in tissues that serve as coverings within the body, such as those found in the cervix, lips and mouth. They are best known as the cells that give rise to squamous cell cancer, one of the more common, and less dangerous, skin malignancies.
