If you were up all night and you ache all over the next morning, your lack of sound slumber might be to blame. New research found that sleep loss delivered a double whammy to the brain that all but guaranteed greater levels of body pain. “Activity in the somatosensory cortex, previously associated with the location and intensity of pain, was enhanced following sleep loss,” explained study author Adam Krause. And “in two regions called the striatum and the insula, sleep deprivation decreased the activity associated with pain [relief],” he added. These regions control the release of dopamine, often called the “feel-good” hormone. Krause is a Ph.D. candidate with the Center for Human Sleep Science at the University of California, Berkeley. During the study, 25 healthy, young participants got the normal eight hours of sleep one night. A week or so later, the same group underwent a night of no sleep whatsoever. After each session, all the volunteers underwent “thermal pain sensitivity” tests, followed by MRI scans to monitor brain activity while their legs were exposed to uncomfortable levels of heat. After a full night of sleep, most participants reported feeling heat discomfort at about 111 degrees Fahrenheit. But after a night of no sleep, that pain threshold dropped to 107 degrees F. Brain scans pinpointed the neurological basis for the uptick in pain sensitivity following…  read on >

The research is in its early days, but Chinese scientists say they’re using bartenders’ tricks to stir up a new, reversible male contraceptive. In experiments with rats, the method successfully kept sexually active males from impregnating females for more than two months. “The two most widely used male contraceptives are condom and vasectomy,” noted a team led by Xiaolei Wang, of Nanchang University. “A reliable and reversible medium-term [2 to 20 weeks] contraceptive method between the one-off condom and permanent contraception is urgently needed.” Their potential solution was inspired by the colorful layered cocktails often concocted by bartenders. In these mixes, liquids form distinct layers in a glass. But when stirred or heated, the layers combine into a uniform liquid. So, Wang’s group developed a form of male contraception in which layers of materials are injected into the vas deferens — the duct through which sperm travels from the testicle to the urethra — to block it. The blockage continues until heat applied to the blocked area causes the layers to mix, breaking them down and thereby unplugging the vas deferens. The Chinese group say they tested this method in male rats by injecting four layers of materials into the vas deferens. In sequence, the injected layers were: a hydrogel that forms a physical barrier to sperm; gold nanoparticles that heat up when irradiated with…  read on >

If you’d like to lighten up on carbs without compromising the taste of dishes you love, make cauliflower “rice” your go-to substitute ingredient. Cauliflower is among the healthiest of all vegetables, high in vitamin C, fiber and folate. “Ricing” it simply means pulsing it in a food processor until chunks become the size of rice grains. Then use them for dishes that call for rice, pasta and even potatoes. This recipe is a great substitute for traditional fried rice, and you can customize it with additional low-calorie vegetables of your choice. For a complete meal, toss in cooked shrimp or chicken cubes at the end. Cauliflower Fried Rice 1 small head cauliflower, cut into florets 3 tablespoons sesame oil, divided 4 carrots, chopped 1 red or yellow onion, peeled and chopped 2 tablespoons ginger, minced 2 garlic cloves, minced 1 cup corn kernels 1/4 cup chopped cilantro 2 tablespoons reduced-sodium soy sauce 1 tablespoon hot sauce Place the florets in a food processor and rough chop in about 15 pulses (do this in a few batches for the most consistent “grains.”). Warm a large skillet over medium heat and add one tablespoon of the sesame oil. Add the cauliflower and cook four to five minutes, stirring well until the cauliflower starts to brown. Transfer to a large plate. Heat the remaining oil in the same…  read on >

Finasteride, best known as the enlarged-prostate medicine Proscar, is a safe, effective way to reduce the risk of prostate cancer, according to long-term findings from the Prostate Cancer Prevention Trial (PCPT). The trial was funded by the U.S. National Cancer Institute and enrolled nearly 19,000 men between 1993 and 1997. Initially it found that finasteride — a hormone-blocking drug — cut the risk of prostate cancer by 25 percent. Those results were published in 2003. The newly released long-term data show that the reduction of prostate cancer risk has continued and that fewer than 100 men in the trial died from prostate cancer in more than two decades of follow-up, according to a research team led by Dr. Ian Thompson. The updated results also showed no statistically significant increased risk of death from prostate cancer among men taking finasteride. This removes concerns over early findings of a possible risk of more aggressive cancers among patients who take the drug. “Finasteride is safe, inexpensive and effective as a preventive strategy for prostate cancer,” said Thompson, who is principal investigator of the PCPT for the SWOG Cancer Research Network. The SWOG Cancer Research Network is an international cancer clinical trials group. “Doctors should share these results with men who get regular prostate-specific antigen [PSA] tests that screen for the presence of prostate cancer,” Thompson said in a…  read on >

For many, a microwave is indispensable, but questions remain about the safety of containers used to cook and reheat food in it. Most of the controversy surrounds the chemicals used to make plastic containers soft or clear, like BPA and phthalates. These chemicals are called endocrine disrupters, because they can mimic hormones such as estrogen in a bad way. The chemicals can leach into your food, especially when containers are heated. According to the nonprofit Environmental Working Group, other chemicals, even replacements for BPA, haven’t been tested enough to know if they’re truly safe. Some experts recommend not using any plastic container in the microwave, even if it is stamped “microwave safe.” Microwaves heat unevenly and can create hot spots where plastic is more likely to break down. Instead, use ceramics or glass labeled microwaveable. Also, rather than covering even a glass dish with plastic wrap, place wax paper, a plain white paper towel or parchment paper over the container before microwaving. If you must use plastic, the Environmental Working Group suggests choosing containers marked with the number 1, 2, 4 or 5. These don’t contain BPA and may be better choices. Avoid polycarbonate containers, which are sometimes stamped with the number 7 or “PC.” If you must wash any plastic in the dishwasher (where high heat can break down the plastic), put them on…  read on >

Most people know how important recycling is for a healthier environment, yet a survey by the Pew Research Center showed that Americans may not always put that knowledge into practice. Though most people in the United States have access to recycling programs, the rules and practices vary within states and even within communities. Only 28 percent of survey participants said their community strongly encourages recycling and re-use. Even when recycling programs exist, not everyone uses them. Some people aren’t fully aware of what exactly can be recycled in their area. This might explain why recycling rates have been on a plateau, after rising for decades. According to the U.S. Environmental Protection Agency (EPA), Americans recycle or compost 1.5 pounds of waste per person per day — the same amount as in 2006. What’s Being Recycled — An EPA Scorecard: 99 percent of lead-acid batteries from cars and trucks. 92 percent of corrugated cardboard boxes. 71 percent of steel cans. 62 percent of major appliances. 55 percent of aluminum beer and soda cans. 30 percent of high-density polyethylene containers such as milk jugs. One bright spot is that people are doing better at creating less trash to start with. That’s fallen from 4.7 pounds per person per day to 4.4 pounds, an amount that could go down even further by tweaking shopping habits. First, look for…  read on >

The average person’s daily diet will need to change drastically during the next three decades to make sure everyone is fed without depleting the planet, a panel of experts has concluded. Global consumption of foods such as red meat and sugar will have to decrease by about half to make sure the Earth will be able to feed a growing population of 10 billion people by 2050, according to the EAT-Lancet Commission on healthy diets from sustainable food systems. At the same time, people will need to double the amount of plant-based foods they eat, including nuts, fruits, vegetables and legumes, experts said. Agriculture must to be redirected to focus on these new food goals, which will put less stress on the environment, researchers said. An effort also will be needed to protect land and ocean resources, and cut food waste globally. While the recommended dietary changes might be wrenching for some, they come with a tremendous benefit in terms of human health, said co-lead commissioner Dr. Walter Willett, a professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health. “About 11 million premature deaths per year could be avoided if everyone adopted this healthy diet,” Willett said. “That’s because this reduces unhealthy parts of the diet but substantially increases health-promoting parts of the diet.” The globally sustainable diet recommended by…  read on >

Money worries may contribute to heart disease in black Americans, a new study suggests. “Stress is known to contribute to disease risk, but the data from our study suggest a possible relationship between financial stress and heart disease that clinicians should be aware of as we research and develop interventions to address social determinants of health disparities,” said study senior author Dr. Cheryl Clark. She is a hospitalist and researcher at Brigham and Women’s Hospital in Boston. Her team analyzed data gathered between 2000 and 2012 from more than 2,200 participants in a long-term study examining heart disease in black men and women in the Jackson, Miss., area. None of the participants had evidence of heart disease at the start of the study. They were asked to rate the level of stress they had in several areas, including financial struggles, such as difficulty paying bills and running out of pocket money. Compared to those without financial stress, the risk of heart disease was nearly three times higher among those with moderate-to-high financial stress, and nearly two times higher among those with mild financial stress, the investigators found. The combination of three important heart disease factors — depression, smoking and diabetes — appeared to explain some of the connection between financial stress and heart disease risk, the study authors said. The findings suggest that financial stress…  read on >

(HealthDay News) — More than 70 percent of U.S. adults are overweight or obese, the National Institute of Diabetes and Digestive and Kidney Diseases says. Are you one of them? Before starting a weight loss plan, you should visit your doctor. The first questions to consider are: How can I change my eating habits so I can reach a healthier weight? How much and what type of exercise do I need to reach a healthier weight? Could I benefit from seeing a nutrition professional or weight-loss specialist? The agency says you should do your research before starting a new weight loss plan. Look for one that will promote healthy behaviors that help you lose weight safely. Also, find one that you will commit to every day, to help keep the weight off permanently.

Anyone who has cared for a hospitalized loved one knows that frequent nighttime sleep interruptions — caused by noise or nursing checks — are a big concern. But in a new study, a Chicago hospital adopted sleep-friendly measures for patients that led to fewer nighttime awakenings without compromising care. Nighttime room entries dropped by 44 percent after researchers educated doctors and nurses on the health consequences of in-hospital sleep deprivation. The researchers also tweaked the hospital’s electronic health records system to avoid unnecessary overnight disruptions. Over a year, patients in the so-called SIESTA unit also experienced an average of four times fewer disruptions for medication dosing and three times fewer for routine vital signs. “We’ve known [inpatient sleep deprivation] is a problem since Florence Nightingale in the 1800s, so why hasn’t it been fixed? It’s a very patient-centered problem that also has health implications,” said study author Dr. Vineet Arora. She’s a professor of medicine at University of Chicago. Arora’s prior research showed that even short amounts of sleep loss among hospital patients were associated with higher blood pressure and higher blood sugar levels during hospitalization. Other research has focused on delirium in sleep-deprived patients, as well as hospital readmission rates, she said. A prior survey of Medicare patients also showed that only 62 percent reported their room was kept quiet at night, Arora noted.…  read on >
