A blood test may one day replace invasive tissue biopsies as a pain-free way to confirm lung cancer and guide treatment, new research suggests. According to investigators, the test is as effective as a tissue biopsy in diagnosing advanced non-small cell lung cancer, by far the leading form of the leading cancer killer. The so-called “liquid biopsy” can also quickly identify tumor gene mutations that match targeted drug therapies — potentially boosting patient survival. The new findings present “a convincing argument for use of the liquid biopsy as a first option for molecular testing in advanced non-small cell lung cancer,” said lead researcher Dr. Vassiliki Papadimitrakopoulou. She’s professor of thoracic head and neck medical oncology at the University of Texas MD Anderson Cancer Center. As the Houston team explained, if a CT scan suggests lung cancer, patients are typically asked to undergo a surgical tissue biopsy. It’s an expensive, invasive procedure that comes with risks and inconvenience to patients. Seeking a way around these procedures, numerous companies have been developing blood-based diagnostic tests for lung cancer. The new study focuses on one such test, called Guardant360, developed by Guardant Health, the company that funded the new study. Blood tests like Guardant360 rely on traces of tumor DNA in blood for clues to the presence of lung cancer and the best way to treat it. In…  read on >

For older adults with a urinary tract infection (UTI), antibiotic treatment should begin immediately to prevent serious complications, a new British study finds. Delaying or withholding antibiotics in this age group can increase the risk of bloodstream infection (sepsis) and death, researchers reported Feb. 27 in the BMJ. The findings suggest that doctors should “consider early prescription of antibiotics for this vulnerable group of older adults, in view of their increased susceptibility to sepsis following UTI and despite a growing pressure to reduce inappropriate antibiotic use,” Paul Aylin and colleagues said in a journal news release. Aylin is a professor of epidemiology and public health at Imperial College London. UTI is the most common bacterial infection in older patients. But concerns about antibiotic resistance have led to reductions in antibiotic use in England, the study authors noted. For the study, the researchers analyzed data on more than 300,000 urinary tract infections among more than 150,000 patients aged 65 and older, between 2007 and 2015. Of those patients, 87 percent were prescribed antibiotics on the day of diagnosis, 6 percent received a prescription within seven days, and 7 percent did not take antibiotics, according to the report. The patients were tracked for 60 days after their diagnosis. After accounting for other factors, the investigators found that sepsis and death rates were much higher among patients with…  read on >

When it comes to getting the best taste and the greatest nutritional value from grains, keep it whole grain. Quinoa, oats, short-grain brown rice and wild rice, polenta (which is made from corn) and barley are most nutritious in their whole, unprocessed form. That’s because the bran is still intact, and the bran is where most of the minerals, vitamins and plenty of fiber reside. Processed and packaged foods are rarely made from 100 percent whole grains. Think of them as empty carbs with lots of preservatives, so switch to these flavorful grains to load up on nutrition, including essential minerals and even some protein. Tip: Don’t be fooled by the word “multi-grain” on packages — this does not mean that a variety of or even any whole grains were used. Brown rice is high in magnesium and tryptophan, barley is high in selenium and tryptophan, and steel cut oats are high in manganese and zinc. These grains are simple to prepare. Bring water to a boil, add your grains and cook on low heat for about 45 minutes until tender. Remove from the heat and keep covered for 5 minutes to allow the grains to fluff, then stir with a fork. Quinoa is another excellent choice, high in iron and manganese, plus it’s quicker to cook than the other grains. Rinse a cup of…  read on >

Your long-term happiness in marriage may hinge on the genes you and your partner bring to the union. A Yale University study suggests marital bliss could be influenced by a genetic variation that affects oxytocin, the so-called “love hormone” that is involved in social bonding. “This study shows that how we feel in our close relationships is influenced by more than just our shared experiences with our partners over time,” said lead author Joan Monin, an associate professor in the Yale School of Public Health. “In marriage, people are also influenced by their own and their partner’s genetic predispositions,” she said in a Yale news release. The study included 178 married couples ranging in age from 37 to 90. The participants were asked about their feelings of marital security and satisfaction, and each provided a saliva sample for genetic testing. When at least one partner had a genetic variation known as the GG genotype within the oxytocin gene receptor, the couple had greater satisfaction and feelings of security in their marriage compared with couples with different genotypes, the researchers found. Previous studies have linked the oxytocin receptor variant, OXTR rs53576, to personality traits such as emotional stability, empathy and sociability. This study is believed to be the first to examine its role in marital satisfaction. The Yale researchers also found that people with the GG…  read on >

Tax it, and fewer folks will buy it. So it goes with sugar-sweetened drinks, new research suggests. The California city of Berkeley introduced the nation’s first soda tax in 2014, and within months people were buying 21 percent fewer sugary drinks. Three years later, 52 percent fewer of these drinks were being sold while consumption of water rose 29 percent, the researchers found. “This just drives home the message that soda taxes work,” said study author Kristine Madsen, faculty director of the Berkeley Food Institute at University of California, Berkeley’s School of Public Health. “Importantly, our evidence comes from low-income and diverse neighborhoods, which have the highest burden of diabetes and cardiovascular disease, not to mention a higher prevalence of advertising promoting unhealthy diets,” Madsen said in a university news release. The study shows that a soda tax can influence what people buy and can be effective in encouraging healthier drinking habits. This could potentially reduce diseases like diabetes, heart disease and tooth decay, which have been linked to sugar, the researchers added. Sugar-sweetened drinks are very cheap, but cost America billions each year, Madsen said. “They’d cost much more if the health care costs were actually included in the price of the soda,” she added. “Taxes are one way of taking those costs into account.” For the study, Madsen and colleagues polled some 2,500…  read on >

It may still be winter, but it’s never too early to plan for your kids’ summer camp. And now’s the time to think about preparing them to handle allergies and allergic reactions, according to experts at the American College of Allergy, Asthma and Immunology (ACAAI). “Kids who suffer from seasonal allergies, food allergies or asthma also wonder about their health. For them, additional preparation is necessary to keep them safe and happy, so they can enjoy their time away from home,” ACAAI president Todd Mahr, said in a college news release. The ACAAI has five tips to help make the summer camp experience a great one. If your child suffers from asthma or food allergies, consider sending him or her to a camp that specializes in these conditions. Specialty camps can have trained staff who know how to treat asthma and allergies. You can search the internet for camps that focus on your child’s needs. Before sending your child off to camp, consult with your allergist and make sure prescriptions are up-to-date and your child has everything needed to treat their allergies or asthma. The allergist can also provide a plan to share with the camp. Be sure the camp’s staff is prepped on your child’s allergies and asthma. They should know if asthma makes some activities difficult. Be sure the medical staff knows about…  read on >

If supermarket circulars influence your grocery shopping, you could be saving money at the expense of your health. That’s because studies show the offerings are often far from the healthiest food choices. Researchers looked at a year’s worth of circulars from a small Midwestern grocery chain to see how the nutritional quality of sale items compared to that of the average American diet, which itself scores low. They found that sales reflected a tendency to eat too much protein and not enough fruits and vegetables. While 25 percent of sale items were for protein-based foods, only 8 percent were for vegetables and 7 percent for fruits. Worse still, less than 3 percent were for the most healthful dark green, red and orange vegetables. So, it’s important not to let these circulars dictate your eating habits. Eating healthy doesn’t have to cost as much as you might think. The difference can be as little as $1.50 more per day. Interestingly, some studies have shown that even people who spend the most money on food don’t automatically select healthier choices. Regardless of budget, the average family spends the biggest chunk of their food budget — about 35 percent — on items like snacks, treats and frozen dinners. That means shifting just some of your shopping dollars may be enough to boost your diet. Once you’re at the…  read on >

(HealthDay News) — Dry, cold air can trigger asthma attacks, the Asthma and Allergy Foundation of America says. Breathing in the winter air can cause airways to restrict, making it difficult to breathe. The foundation offers suggestions to reduce asthma attacks during winter: Cover your mouth with a scarf. Exercise indoors, not outdoors. Always carry your quick-relief inhaler with you. Talk to your doctor about pretreatment plans.

Obesity and severe obesity have been added to the list of conditions that put children and teens at increased risk for early heart disease. So says a new scientific statement from the American Heart Association (AHA). “Parents need to know that some medical conditions raise the chances of premature heart disease, but we are learning more every day about how lifestyle changes and medical therapies can lower their cardiovascular risk and help these children live their healthiest lives,” statement writing group chair Dr. Sarah de Ferranti said in an AHA news release. She is chief of the Division of Cardiology Outpatient Services at Boston Children’s Hospital. The latest statement is an update of a 2006 statement. Other conditions that increase the risk of early heart disease in children and teens include type 1 and type 2 diabetes, familial high cholesterol, congenital heart disease, and surviving childhood cancer. Severe obesity and obesity are now included as moderate-risk and at-risk conditions, respectively, because research shows they significantly increase the risk of heart disease later in life, according to the AHA. For example, a study of nearly 2.3 million people who were followed for over 40 years found that the risk of dying from heart disease was two to three times higher if they had been overweight or obese as teens. In general, a gradual approach to weight…  read on >

Nuts and seeds are often mentioned in the same breath, but nuts seem to get all the attention. Time to stop overlooking seeds — they might be tiny, but they pack in a lot of nutrients. They’re also tasty and some make a filling snack. Like nuts, seeds have protein, carbohydrates and fats. Because of their fat content, they’re calorie-dense, and a half-ounce — weighed without the shell, about one tablespoon — is equivalent to an ounce of protein. Flax seeds are especially good for you because of their high omega-3 content and both soluble and insoluble fiber. To get the most benefits, buy them whole, keep them in the fridge and grind them as you need them (not in advance) — easily done in a coffee bean grinder. Besides sprinkling ground flax on cereal and yogurt, add it to smoothies, ground meat dishes and pancake, waffle and muffin batters. You can even use it instead of breadcrumbs. Sunflower seeds are a tasty source of vitamin E, some B vitamins and a wide array of minerals. They’re great when sprinkled over salads or creamy vegetable soups as well as on their own. Pumpkin seeds, also called pepitas, are another great choice, a good source of protein, zinc and antioxidants. You can buy them when shelled or unshelled, but it’s easy to roast your own anytime…  read on >
