Pet owners care deeply about what their furry family members eat. So should they worry about a new study that finds chemical preservatives known as parabens are often in dog and cat food, as well as in urine samples from the animals? Maybe, researchers say, though there’s no need to panic. “Parabens are reported as endocrine-disrupting chemicals,” said the study’s senior author, Kurunthachalam Kannan. These preservatives can interfere with hormones and may have harmful effects on developmental, reproductive and neurological systems, explained Kannan. He’s with the New York state Department of Health’s division of environmental health sciences. But the levels of parabens and their by-products found in pets are low, according to the new study. “The current exposure levels of parabens and their metabolites in cats and dogs are 100- to 1,000-fold less than the tolerable daily intake limits,” Kannan said. However, the safe levels were based on research in humans, and it’s possible that pets are more sensitive, he added. The researchers pointed out that diseases — such as diabetes, kidney diseases and thyroid problems — have been rising in pets that primarily stay indoors compared to those who live outside exclusively. And some scientists have proposed that chemical exposures in the home could play a role in these illnesses. So far, no studies have confirmed any harmful effects from paraben exposure, according to…  read on >

(HealthDay News) — Smoking is associated with 1 in 5 deaths in the United States, according to the National Heart, Lung, and Blood Institute. The agency suggests these methods that may help you quit: Commit to quitting and get motivated to make a change. Get support from friends and family. Consider using medicine to help you quit, and if you do, use it correctly. Take up a new hobby as a distraction. Be prepared for the effects of withdrawal and the possibility of relapse.

U.S. war veterans who sustained severe combat wounds and have chronic post-traumatic stress disorder (PTSD) are at increased risk for high blood pressure, a new study says. The study included nearly 3,900 military veterans who had been severely wounded in Iraq or Afghanistan from February 2002 to February 2011. Their average age when they were wounded was 26. More than 14 percent of the veterans developed high blood pressure at least 90 days after being wounded. The severity of the injuries and how frequently PTSD was noted in their medical records after the wounding separately affected their risk for high blood pressure. “What we found surprised us,” said study senior author Dr. Ian Stewart, a major at the U.S. Air Force Medical Center at Travis Air Force Base in California. For every 5-point increase on a 75-point injury severity score, the risk for high blood pressure rose 5 percent. Veterans with an injury severity score of 25 or lower and no recorded PTSD diagnosis had the lowest risk for high blood pressure, according to the study. Compared with veterans with no PTSD diagnosis, the risk for high blood pressure was 85 percent higher among those who had PTSD noted one to 15 times in their medical records — indicating chronic PTSD. High blood pressure was 114 percent more likely among veterans with PTSD noted more…  read on >

One-third of young adults in the United States have been in a vehicle with a driver impaired by alcohol or drugs, a new study finds. Riding with a marijuana-impaired driver was more common than riding with an alcohol-impaired driver, researchers found. “We’ve put a lot of emphasis on drinking and driving, but less effort on driving under the influence of marijuana. Maybe we need more of the latter,” said study lead author Kaigang Li. “Parents should be a role model by not driving while impaired, and real friends should stop their friends from driving after using substances — if using substances cannot be stopped,” said Li, an assistant professor of health and exercise science at Colorado State University. For the study, the researchers analyzed 2013-2014 national survey data gathered from young adults who graduated high school within the past two years. Thirty-three percent reported riding with an impaired driver at least once in the previous year. Of those, 23 percent said they were with a pot-impaired driver, and 20 percent were with a booze-impaired driver. Six percent said they had ridden with a driver hampered by drugs other than marijuana, including ecstasy, amphetamines, opiates, cocaine/crack cocaine, glue or solvents, LSD or anabolic steroids. The findings were published in the March issue of the Journal of Studies on Alcohol and Drugs. “Emerging adults are entering the…  read on >

Tiny pellets could treat arthritic knee pain, delaying the need for knee replacement surgery, a small study has found. Microparticles inserted into small blood vessels around the knee helped reduce the pain and improve function in eight arthritis sufferers, according to clinical trial results. The results were presented Monday at the Society of Interventional Radiology’s annual meeting, in Los Angeles. “Patients overall were able to improve their physical function in the knee after the procedure, and there were no adverse events related to this treatment,” said lead researcher Dr. Sandeep Bagla. Bagla is director of interventional radiology at the Vascular Institute of Virginia in Woodbridge. Boston Scientific, maker of the microparticles, funded the study. Much of the pain that comes from knee arthritis actually stems from inflammation in the lining of the knee joint, also called the synovium, Bagla said. In fact, small blood vessels created by degenerative arthritis feed this inflammation by increasing blood flow to the lining. To treat this, Bagla and his colleagues decided to try blocking those tiny blood vessels using microparticles — spheres about a tenth of a millimeter in size made from a synthetic gel-like material. The microparticles are inserted using a catheter run through a pinhole-sized incision, in a procedure that lasts between 45 and 90 minutes, Bagla said. “It’s an outpatient procedure, and no physical therapy is…  read on >

If you’re planning a career change or wondering if a challenging job could have positive effects, research might provide some intriguing answers. In a 2014 study, scientists in Scotland used levels of job complexity based on the Dictionary of Occupational Titles for an analysis of more than 1,000 participants with an average age of 70. They found that two types of complex jobs lead to longer-lasting memory and thinking ability, years after retirement. One is working at a high level with data. The other is working at a high level with other people, on tasks like teaching, negotiating and mentoring. According to the lead author of the study, the theory is that more stimulating work environments may help people retain these mental skills. While the effect of occupation accounts for just a 1 to 2 percent variance between people with high- and low-complexity jobs, that differential is similar to some lifestyle factors that affect better thinking skills in later life, such as not smoking. The most complex jobs involving data include: Architect. Civil engineer. Graphic designer. Musician. The least complex jobs involving data include: Construction worker. Telephone operator. Food server. The most complex jobs involving other people include: Surgeon. Lawyer. Social worker. Probation officer. The least complex jobs involving other people include: Factory worker. Painter. Carpet layer. Bookbinder. Do complex jobs buffer the brain, or…  read on >

(HealthDay News) — Eating one serving of green leafy vegetables per day is associated with slower age-related cognitive decline, recent research suggests. Reported in the journal Neurology — the study involved 960 adults with an average age of 81 and no sign of dementia. The difference between those who ate the greens and those who did not was equivalent to being 11 years younger cognitively. The vegetables eaten included kale, spinach and collards, which are rich sources of cognition-supporting folate, phylloquinone, nitrate, α-tocopherol, kaempferol and lutein, said the researchers at Chicago’s Rush University and Boston’s Tufts Human Nutrition Research Center.

Think you could taste the difference between recycled toilet water, bottled water or tap water? It’s unlikely, results of a blind taste test suggest. Years of drought in California have given momentum to household use of recycled wastewater. Six water agencies in the state already use wastewater that’s produced through a technology called indirect potable reuse (IDR), the University of California, Riverside, researchers noted. The IDR approach redirects treated wastewater into groundwater supplies, where it re-enters the drinking water system. Although research has shown that recycled wastewater is safe, people are often repulsed about things such as taste. “It seems that this term [wastewater], and the idea of recycled water in general, evokes disgust reactions,” said study author Daniel Harmon, a graduate student in psychology. “It is important to make recycled water less scary to people who are concerned about it, as it is an important source of water now and in the future,” Harmon said in a university news release He and his colleagues asked 143 people to compare the taste of IDR tap water, conventional groundwater tap water and bottled water. “The groundwater-based water was not as well liked as IDR or bottled water,” said study co-author Mary Gauvain, a professor of psychology. “We think that happened because IDR and bottled water go through remarkably similar treatment processes, so they have low levels…  read on >

(HealthDay News) — While a smoothie can be a nutritious alternative to a regular meal, many smoothies are loaded with sugar and lack sufficient protein. The American Council on Exercise suggests how to make a smoothie that’s more nutritious: Start with a heaping portion of romaine, chard, kale, parsley, mint or any other green leafy vegetable. Add fruit to sweeten the smoothie instead of added sugar. But ensure that the mix of greens is twice as much as fruit to keep calories down. Add protein in the form of protein powder, non-fat milk, Greek yogurt, nuts, nut butter or hemp seeds. Add a liquid to make it easier to blend, such as coconut water, water or unsweetened nut milk.

Knee replacement patients can continue to enjoy sports — such as skiing, tennis and dancing — without worrying that high-impact activities might compromise their new joint, a small, new study finds. The researchers tracked patients for between five and 15 years after knee replacement surgery, known as total knee arthroplasty. They found that sports participation had no significant impact on the longevity of artificial knees. Historically, knee replacement patients are advised against high-impact activities to preserve the new joint. “Patients were coming back for their annual review . . . and were participating in a range of ‘prohibited’ activities. There were patients competing in downhill skiing and tennis, but there was no wear, no dislocations, no loosening and no revisions,” said study author Dr. Samuel Joseph. He’s an orthopedic surgeon at Linacre Private Hospital in Melbourne, Australia. “Yes, there are patients running marathons and participating in triathlons after knee replacement surgery,” he added. More than 600,000 knee replacements are performed each year in the United States, according to the U.S. Agency for Healthcare Research and Quality. The procedure replaces the natural joint with a prosthetic version made of metal and plastic. It’s typically done because of severe arthritis, trauma or other joint damage. Joseph and his colleagues identified 355 knee replacement patients who continued to participate in sports after surgery, more than 100 of whom…  read on >
