Want to know how to avoid blood clots and varicose veins? One physician offers some tips on how to keep your blood vessels healthy. Arteries and veins are collectively known as the vascular system. Arteries transport oxygen and nutrient-rich blood throughout the body, while veins carry de-oxygenated, waste-filled blood back to the heart to be renewed, explained Dr. Chelsea Dorsey, a vascular surgeon from University of Chicago Medicine. Problems can occur in both arteries and veins. It’s estimated that 12%-20% of people older than 60 have peripheral arterial disease (PAD), and more than 40% of women have venous insufficiency, the underlying condition that leads to varicose and spider veins. Blood clots in veins can occur at any age, and people at risk include those who are sick, injured or unable to walk for a period of time, and women who take birth control pills. Varicose veins are more common among younger people, and women are twice as likely as men to be affected, Dorsey noted. Problems in arteries — such as atherosclerosis (narrowing or hardening of the arteries) — tend to increase with age. The health of your arteries and veins is influenced by both genetics and lifestyle. For example, the most common risk factors for varicose veins and venous insufficiency include a family history of these conditions, spending long periods of time on your… read on >

(HealthDay News) — One of the simplest ways to maintain healthy vision is to protect your eyes from injury, says the American Academy of Ophthalmology. About 90 percent of eye injuries involve lack of protective eyewear. Whether you’re maintaining equipment or playing sports, wearing appropriate protective eyewear is very important, the doctor’s group says.

If you want to slow down the aging process, it might not hurt to replace whole milk with skim, new research suggests. The study of over 5,800 U.S. adults found that those who regularly indulged in higher-fat milk had shorter telomeres in their cells — a sign of accelerated “biological aging.” The findings do not prove that milk fat, per se, hastens aging, stressed researcher Larry Tucker, a professor of exercise sciences at Brigham Young University in Provo, Utah. But the study does lend support to what U.S. dietary guidelines suggest for adults: If you’re going to drink cow’s milk, opt for low-fat or skim, Tucker said. Telomeres are bits of DNA that sit at the tips of your chromosomes — like the plastic caps at the ends of a shoelace. In essence, they help keep the chromosomes from fraying and sticking together. As people age, their telomeres gradually get shorter, and research has linked shorter telomere length to a higher risk of developing and dying from infections, cancer and heart disease. “A variety of lifestyle factors are also related to telomere length,” Tucker said. Obese people, for example, tend to have shorter telomeres than lean people, as do smokers versus nonsmokers. And people who eat lots of fiber, vegetables and fruit typically have longer telomeres than those who shun those foods. So for the… read on >

From carpal tunnel to a stiff neck, too much time on the computer can cause a slew of health problems. But what if you ditch the keyboard and mouse for virtual reality? New research from Oregon State University in Corvallis showed that even stepping into virtual reality may be bad for the body. Virtual reality isn’t just for playing games. It’s also used for education and industrial training. In most cases, a headset is worn and users are expected to perform full-body movements. But common virtual reality movements can result in muscle strain and discomfort, the study found. “There are no standards and guidelines for virtual and augmented reality interactions,” said study author Jay Kim, assistant professor in the College of Public Health and Human Sciences. “We wanted to evaluate the effects of the target distances, locations and sizes so we can better design these interfaces to reduce the risk for potential musculoskeletal injuries.” For the study, the researchers placed sensors on participants’ joints and muscles during virtual reality sessions, and asked them to point to specific dots around a circle or to color in an area with their finger. The tasks were repeated at varying degrees above and below eye level. At all angles, extending the arm straight out caused shoulder discomfort in under 3 minutes, the study found. Over the long-term, virtual reality… read on >

(HealthDay News) — Athlete’s foot is a fungal infection that often occurs in people who wear damp socks or tight shoes, says Mayo Clinic. The infection is contagious and is spread by contact with an infected person or contaminated surfaces. To help prevent athlete’s foot, the clinic suggests: Keep your feet dry, especially between your toes. Change socks regularly. Wear light, well-ventilated shoes. Alternate pairs of shoes. Protect your feet in public places. Treat your feet with antifungal powder. Don’t share shoes.

For people with the mysterious chronic pain condition fibromyalgia, researchers say nerve stimulation may offer some relief. In a recent study, use of TENS — transcutaneous electrical nerve stimulation — during movement or activity was shown to significantly reduce pain associated with fibromyalgia after just four weeks. Dr. Lesley Arnold, who was not involved with the new study, lauded its outcomes. “The improvements in pain and fatigue were remarkable,” she said. Arnold, a professor of psychiatry and behavioral neuroscience at the University of Cincinnati College of Medicine, suggested that the study may help guide physicians in use of TENS for symptom management. TENS uses a battery-operated machine to deliver electrical currents via electrodes attached to the skin. This is believed to activate nerve pathways that inhibit pain. People with fibromyalgia are encouraged to engage in physical activity as a way to manage their symptoms. But, paradoxically, movement can be painful for them. In the study, researchers randomly divided more than 300 women with fibromyalgia into three groups: active TENS; placebo (sham) TENS; or no TENS. Those in the TENS groups were instructed to use the device over four weeks, at home, for two hours daily during activity. The patients were told to apply the device’s electrodes to two specific areas along the back — one upper and one lower — and to activate the machine… read on >

In another step toward using artificial intelligence in medicine, a new study shows that computers can be trained to match human experts in judging the severity of prostate tumors. Researchers found that their artificial intelligence system was “near perfect” in determining whether prostate tissue contained cancer cells. And it was on par with 23 “world-leading” pathologists in judging the severity of prostate tumors. No one is suggesting computers should replace doctors. But some researchers do think AI technology could improve the accuracy and efficiency of medical diagnoses. Typically, it works like this: Researchers develop an algorithm using “deep learning” — where a computer system mimics the brain’s neural networks. It’s exposed to a large number of images — digital mammograms, for example — and it teaches itself to recognize key features, such as signs of a tumor. Earlier this month, researchers reported on an AI system that appeared to best radiologists in interpreting screening mammograms. Other studies have found that AI can outperform doctors in distinguishing harmless moles from skin cancer, and detecting breast tumor cells in lymph node samples. The new study looked at whether it’s possible to train an AI system to detect and “grade” prostate cancer in biopsied tissue samples. Normally, that’s the work of clinical pathologists — specialists who examine tissue under the microscope to help diagnose disease and judge how… read on >

(HealthDay News) — If you cannot stop picking at scabs or bumps, you may have a condition called skin picking disorder (SPD). The urge to pick at the skin affects at least 5 million Americans, says Harvard Medical School. To tackle the issue, the school suggests: Know your triggers. It can help a doctor decide which treatment to pursue. Make it more difficult to pick by keeping your nails short or wearing gloves. Distract your hands with silly putty, a stress ball or fidget toy. Consider therapy.

(HealthDay News) — It is important to remember that apple cider vinegar is not a magic cure-all. But it does have some health benefits, says the University of Chicago Medicine. The school says the product may: Help control blood sugar. Decrease levels of salmonella in food. Moderately boost the ability to lose weight. But the school says apple cider vinegar won’t: Control high blood pressure. Prevent or cure cancer.

A diagnosis of generalized anxiety disorder need not be a life sentence, a large Canadian study suggests. “It’s so exciting,” said lead author Esme Fuller-Thomson, director of the Institute for Life Course and Aging at the University of Toronto. People with generalized anxiety disorder worry excessively for long periods, and most days they struggle to control their discomfort, according to the Anxiety and Depression Association of America. Anxiety affects an estimated 31% of U.S. adults, is almost twice as common in women than men, and often goes hand-in-hand with major depression. Fuller-Thomson’s team combed data from a 2012 Canadian mental health survey of just over 21,000 people in search of factors associated with “complete mental health.” Of those surveyed, about 2,100 had generalized anxiety disorders. Researchers defined complete mental health as being free of current mental illness, being able to function well and feeling good about oneself, relationships and community connections. Of those with a history of anxiety, 72% were in remission; 58% were free of all mental illness for the past year; and 40% met the criteria for complete mental health. Among the larger group of respondents who had never had a generalized anxiety disorder, 76% were said to have complete mental health. “I didn’t expect the numbers to be so high,” Fuller-Thomson said. “It did surprise me.” The study did not look at… read on >
