Mayo Clinic researchers recently published a study that shows the proper use of masks reduces the spread of respiratory droplets. The findings strongly support the protective value and effectiveness of widespread mask use and maintaining physical distance in reducing the spread of COVID-19. Reporter Jason Howland has more in this Mayo Clinic Minute.
ACL tears can sideline an athlete or crush an Olympic dream. It’s a common knee injury affecting nearly twice as many women than men. Dr. Cedric Ortiguera, a Mayo Clinic orthopedic surgeon and sports medicine specialist, says 150,000‒200,000 ACL injuries occur each year in the U.S., and that number is growing as more children become involved in competitive sports year-round. The good news is that surgery can help get some athletes get back in the game.
Although growing older comes with a number of major life changes, science can help inform the things we do in the here in and now to forestall the most serious features of the aging self, promoting healthspan and not just lifespan.
- Build Muscle – Muscle mass is one the best predictors of health and longevity. Muscle tissue is known to release its own chemicals called myokines, which can have benefits that span cognition, immunity and anti-cancer activity. By performing regular, resistance-based exercise that prioritizes strength, we can delay the loss of bone density and risk of physical injuries.
- Vitamin D – Commonly known as the sunshine vitamin, vitamin D is in fact a critical hormone that helps maintain healthy bones, boost our immune system and improve our cardiovascular function. With age, the production of vitamin D in the skin can become less efficient, so if we don’t spend enough time outdoors, our risk of vitamin D deficiency may increase.
- Neurodegenerative Diseases – One of the most unsettling aspects of aging is the potential for neurodegenerative disease. These conditions are increasingly prevalent in those with diabetes, suggesting that the brain’s blood flow and energy supply may be compromised. Research indicates that regular physical exercise, a healthy whole foods diet and staying intellectually active could at least slow the rate of decline.
- Mindfulness – As we get older, major arteries can become thicker and less flexible, leading to increased blood pressure and undue strain on the heart. A regular mindfulness practice such as yoga or meditation has been shown to stem the release of stress hormones like cortisol and adrenaline. By freeing us from this “fight-or-flight” state, this habit can improve blood flow and reduce the risk of heart attack and stroke.
- Stay Social – As social animals, maintaining a strong sense of community and close personal relationships into old age are underestimated contributors to longevity. While social isolation in seniors can result in significant physical and mental decline, research suggests that close loved ones offer important emotional support and behavioral modifications that can overcome periods of high stress.
- Metabolism – “My metabolism is slowing down!” That’s what we often hear, as the aging body becomes less effective at using energy, placing us at risk of obesity and type 2 diabetes. By maintaining our muscle mass and reducing sugar consumption, we can support hormonal health, preserve our metabolism and keep our vitality into those advanced years. As scientists continue to find ways to extend our lives, paying attention to these keys to healthy aging can help increase the quality of those extra years.
A new approach developed by Harvard Medical School researchers uses yeast to rapidly evolve synthetic antibody fragments called nanobodies with the aim to find variants that are effective at binding to selected antigens, including SARS-CoV-2. The antibodies are intended for use in diagnostic tests and disease treatments. Read the full story: https://hms.harvard.edu/news/antibody…SHOW LESS
The mission of COMPASS is to provide patients with access to comprehensive quality and safety data across a variety of Massachusetts General Hospital surgical specialties. In this video, learn about performance data for Mass General hip replacement surgery including its success rate and recovery and rehabilitation.
When it comes to fighting cancer or living with a cancer diagnosis, does what you eat make a difference? On Mayo Clinic Q&A, Dr. John Shin, a hematologist/oncologist, discusses nutrition and cancer.
The Endocrine Surgery Program at Massachusetts General Hospital provides multidisciplinary, specialized treatment for thyroid nodules, a lump that commonly occurs in the thyroid. If you think that you may have a thyroid nodule, you should be evaluated by a physician. In this video, Sareh Parangi, MD, endocrine surgeon at Mass General, shares more about what to expect for diagnosis and treatment of thyroid nodules.
The patient is awake as a laser cuts her cataract into six pieces. Then, she heads into the operating room. When she wakes up, her cataracts and nearsightedness are gone.
Focal One® high-intensity focused ultrasound uses high-intensity sound waves to destroy a cancer tumor. It’s delivered through a rectal ultrasound probe. There are no incisions. Most patients need no pain medication after treatment. And there are fewer side effects than with radiation therapy or prostate removal.
