Moderation Is Recommended

1 High Heels May Be Detrimental to Women’s Joints

Prolonged wearing of high heels may contribute to knee osteoarthritis and joint degeneration, finds an Iowa State U student’s master’s thesis. While researcher Danielle Barkema says that heels don’t automatically cause the wearer to develop osteoarthritis, she states that there’s a greater risk for those who do and “the higher the heel height, the greater the risk.” Using sensitive measuring devices, Barkema tested three varying heel heights on 15 participants to capture motion and force data and found that as heels got higher, compression on the knee joint became more forceful. Barkema also found that wearing heels puts strain on the lower back and ankle. While Barkema does not tell women to abandon heels, she suggests wearing them in moderation.

LDL Matters Even in 20s

2 Cholesterol Levels in 20s, 30s Important

It's time to start paying more attention to cholesterol levels in young people, suggest researchers who found that even modestly elevated cholesterol during a person's 20s and 30s can raise risk of developing coronary artery calcium and atherosclerosis later in life. Findings from the 20-year study were released recently by University of California - San Francisco researchers. They found that people with higher levels of LDL cholesterol or lower levels of HDL cholesterol in young adulthood turned out to be more likely to have coronary calcium later in life. Researchers found that 44 percent of people in the study with average LDL greater than 160 mg/dL had calcifications in coronary arteries 20 years later, compared with only eight percent of those with LDL levels less than 70 mg/dL.

Gaining Not Recommended

3 Higher Weight in Women May Reduce Glaucoma Risk

Maintaining a healthy body weight is important for avoiding many diseases, but glaucoma may not be one of them. In a large study from the Massachusetts Eye and Ear Infirmary (MEEI), women with higher BMI’s had a lower risk for a variant of primary open-angle glaucoma (POAG) known as normal tension glaucoma (NTG). The same association was not found in overweight men. POAG is the most common type of glaucoma, a potentially blinding illness that damages the optic nerve. People with NTG have damage even though intraocular pressure or IOP is not elevated. NTG occurs in about 15-25 percent of people with open-angle glaucoma. Dr. Louis Pasquale says that patients should be cautious about these findings, as the relationship between BMI and NTG is not clear.

Maturity Wins with Stem Cells

4 Adult Stem Cells Provide Many Therapies

While embryonic stem cells have provided with a lot of insight, it is adult stem cells that have provided the medical community with therapies that doctors are currently studying. In one case a man’s stems cells were used to heal a broken ankle, they are being studies in people suffering a variety of diseases and one group of researches demonstrated adult stem cells could restore vision to those who suffered chemical eye damage. Hematological conditions and some cancers are cured with transplants of adult stem cells. Adult stem cells are not surrounded in controversy like their embryonic counterparts. There is a lot of hope about future therapies using adult stem cells but that is dampened by clinics out there making claims about stem cell therapy that cannot be scientifically validated.

Hope Is a Reward in Parkinson's

5 Hope of Getting Parkinson’s Drug Releases Dopamine

Brain scans of people with Parkinson’s disease who were told they had a 75 percent chance of receiving levodopa showed dopamine was released even though they only received a placebo. Some of the 35 individuals were also told they had a 25, 50 and 100 percent chance of receiving the drug but only received the placebo as well, but the response was only seen in the 75 percent chance group. Sarah C. Lidstone, of the Pacific Parkinson's Research Centre at Vancouver Coastal Health and the University of British Columbia, Vancouver, and colleagues wrote that "This is in keeping with studies on conditioned learning in which dopaminergic activation is seen when reward is deemed likely but not certain." The study can be found in the August issue of the journal Archives of General Psychiatry.
