_ Toxic Substances Make You Older By Jane Farrell article Environmental toxins play a significant part in your molecular aging, according to new research. Researchers from the University of North Carolina at Chapel Hill say toxins that affect the rate of such aging include benzene, cigarette smoke and even stress. Molecular age refers to the age of the bodyΓÇÖs cells, and is different from chronological age.
_ Skin Skin Health Indoor Tanning Ups Melanoma Risk By Jane Farrell article If you or your teenage children or grandchildren believe that getting an indoor tan will prevent burns from outdoor sun exposure, youΓÇÖre courting the deadliest form of skin cancer. ThatΓÇÖs the finding of researchers at the University of Minnesota who published their study May 29th 2014 in the JNCI: Journal of the National Cancer Institute. The team reports that indoor tanning raises the risk of developing melanoma even if a person has never had burns from either indoor or outdoor tanning.
_ Breast Cancer Chemotherapy and Hospitalization By Jane Farrell article Scientists have zeroed in on which chemotherapy regiments are likelier to lead to hospitalizations for early stage breast cancer patients. The retrospective study, published in the Journal of Clinical Oncology, was conducted by researchers from the University of Texas MD Anderson Cancer Center. For their analysis, the researchers looked at hospitalization-related insurance claims by patients who were undergoing varying chemotherapy regimens.
_ Common Beliefs About Obesity Could Be Wrong By Jane Farrell article Why do we have an obesity epidemic? Experts have come up with a number of reasons, and most of them might be wrong, according to new research. The findings, by investigators from the University of Illinois, Champaign, indicate that people have better access to fresh, affordable food than they did years ago.
_ Digestive Health Possible Breakthrough for IBD Tx By Jane Farrell article A microRNA cluster believed to be important for suppressing colon cancer plays a critical role in wound healing in the intestine, according to researchers at the University of Texas Southwestern Medical Center in Dallas. The findings could provide a fresh avenue for investigating chronic digestive diseases and for potentially repairing damage in these and other disease or injury settings. A release from the medical center quotes Dr. Joshua Mendell as saying, "We identified a novel role for microRNAs in regulating wound healing in the intestine.
_ Understanding Your Blood Work By Jane Farrell article From the Mayo Clinic A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including: Red blood cells, which carry oxygen White blood cells, which fight infection Hemoglobin, the oxygen-carrying protein in red blood cells Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood Platelets, which help with blood clotting Abnormal increases or decreases in cell counts as revealed in a
_ Breast Cancer Double Mastectomy DoesnΓÇÖt Increase Survival By Sondra Forsyth article Many women diagnosed with cancer in one breast undergo a contralateral prophylactic mastectomy (CPM) to remove both breasts. Yet removing the unaffected breast has not been shown to increase survival, according to a study done at the University of Michigan and published online May 21st 2014 in Jama Surgery.
_ How to Have Healthy Air At Home By Jane Farrell article One of the best things about warmer weather: throwing open the windows to let in some fresh air. But that doesnΓÇÖt automatically mean that the air in your house is healthy, or even safe. If you want to keep your house a healthy place for you, your family and your pets, the American Lung Association has some suggestions: If you havenΓÇÖt already, make your home a smoke-free zone. DonΓÇÖt let anyone smoke inside; if they want to inhale, they can go a safe distance away from the house, so smoke wonΓÇÖt blow in through your windows. Have a radon test, the ALA says.
_ Which Prostate Surgery Is Better? By Jane Farrell article Robotic surgery, the primary choice for removing cancerous prostate glands, is as safe as open surgery for Medicare patients over 65, according to a new survey. The findings came in a survey that included analysis by researchers from Henry Ford Hospital. The hospital is a pioneer in robot-assisted radical prostatectomy (RARP), a minimally invasive procedure. ΓÇ£Although studies comparing the two techniques were done early in the robotic era for this surgery, RARP boomed in more recent years, overtaking open surgery,ΓÇ¥ says study co-author Jesse D.
_ The "Diet" Antibiotic By Jane Farrell article Researchers have found exactly how a drug works to mimic the action of eating well and, as a result, possibly extending lifespan. The drug, an immunosuppressant and antibiotic called Rapamycin, was approved for use about 15 years ago.
_ Low Risk Prostate Ca Not Always Low Risk By article The criteria for active surveillance -- often called ΓÇ£watch and waitΓÇ¥ -- in dealing with prostate cancer should be re-evaluated. That is the recommendation of a study done at the University of California, Los Angeles and published in the May 19th 2014 issue of the peer-reviewed Journal of Urology.
_ Healthy Diet & Nutrition The Importance of Prebiotics and Probiotics By Sondra Forsyth article By Sondra Forsyth Both prebiotics and probiotics are essential components of a healthy diet. Prebiotics are indigestible carbohydrates that act as food for probiotics, which contain live bacteria. Together, they help promote the growth of the good bac- teria in your intestines and maintain your gut’s ecosystem. When a food contains both substances, it is called synbiotic: a synergistic combination of the two. Prebiotics
_ Aggressive Tx for Older Prostate Patients a Mistake By article Treating older men with early-stage prostate cancer who also have other serious underlying health problems with aggressive therapies such as surgery or radiation therapy does not help them live longer and, in fact, can be detrimental, according to a study done by researchers at the University of California, Los Angeles. The study was published in the May 13th 2014 early online edition of the peer-reviewed journal Cancer.
_ Osteoporosis Do You Really Need Vitamin D Supplements? By article You may have heard that researchers who analyzed hundreds of studies have concluded that vitamin D supplements won’t protect healthy, middle-aged adults from osteoporosis. And even worse, the scientists say the supplements may increase the risk of death from other diseases. However, none health experts at the Cleveland Clinic warn that you need to make sure you aren’t deficient in vitamin D before you stop taking the supplement, especially if you are past menopause.
Vision Health Plugging Blood Vessels to Save Vision By article The growth of malformed blood vessels that can burst is a leading cause of vision loss in North America. Retinopathy and retina degeneration are associated with premature birth, with diabetes, and with increasing age. Now a new drug approach has been developed by a research team led by Dr. Andras Nagy at the Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital in Toronto for safer clean-up of deformed blood vessels in the eye. The study was published in May 2014 in EMBO Molecular Medicine.

_ Free Radicals May Be Good Guys After All By article Free radicals, the sometimes-toxic molecules produced by our bodies as we process oxygen, have received a lot of bad press claiming that they are they are the culprits behind aging. Yet a number of studies have found evidence that the opposite may be true. Most recently, researchers at McGill University in Montreal have shown that free radicals promote longevity in the roundworm C. elegans. Surprisingly, the team discovered that free radicals – also known as oxidants – act on a molecular mechanism that, in other circumstances, tells a cell to kill itself.
