— (HealthDay News) Even with long-term treatment, HIV can still be found in the cerebrospinal fluid of some people with the AIDS-causing virus, a new study reports. And these patients are at increased risk of having thinking problems, the researchers say. “It is difficult to target infections that lurk in the brain, and HIV is probably not an exception to the rule,” said study senior author Dr. John Mellors, chief of infectious diseases at the University of Pittsburgh. “We have our work cut out for us in the quest for an HIV cure, but knowing is half the battle, so I’m cautiously optimistic,” he said in a university news release. Researchers analyzed cerebrospinal fluid from 69 people with HIV who had been on anti-HIV therapy for an average of nine years. The study found that nearly half the participants had cells harboring HIV. Of those who had HIV-harboring cells in their cerebrospinal fluid, 30% met criteria for thinking problems (cognitive impairment), compared with 11% of those without HIV-harboring cells in their cerebrospinal fluid. The findings may help explain why people with well-controlled HIV can have memory and concentration problems and difficulty completing complex tasks, according to the researchers. They also said that the results show that the brain is an important reservoir for HIV, a challenge that needs to be considered in clinical trials of… read on >

Imagine this: You open a bag of fresh salad greens and out pops a lizard. Or worse. Unfortunately, that scenario is more common than many might think. Researchers analyzed online news between 2003 and 2018 and found 40 articles about U.S. consumers discovering live, dead or severed parts of animals in their produce. More than half of the cases involved frogs, but lizards, snakes, mice, birds and even a bat were found in salad greens, green beans or mixed vegetables. Ten of the animals — nine frogs and one lizard — were found alive. In three-quarters of the cases, the produce was conventionally grown, not organic. “It was implied over and over in these articles: If you buy organic, getting a frog is par for the course, essentially,” said study author Daniel Hughes, a postdoctoral researcher in the Department of Animal Sciences at the University of Illinois. “If that was true, we should have seen the opposite of what we found. We did not take into account market-share differences between conventional and organic produce, but this result ran contrary to common opinion,” Hughes said in a university news release. Only one of the incidents — a dead bat found in a package of salad greens in Florida in 2017 — led to a recall, according to the study published on July 20 in the journal… read on >

If you skip or skimp on breakfast, grab a quick lunch and then load up at dinner, your food intake is likely out of sync with your body’s needs. Not getting calories when you really need them (hint: during the day) could be why you’re having a hard time shedding pounds or finding the energy to exercise. Here’s how to rebalance your calorie intake. One approach, recommended by sports fitness dietitian Nancy Clark, is to divide your daily intake into four equal meals — breakfast, lunch, a second lunch eaten midafternoon, and dinner — with the calories for the second lunch coming from the ones you’re probably taking in during late-night snacking. This keeps your body fueled throughout the day so you have the energy you need when you need it. Front loading calories also seems to speed weight loss, according to research published in the International Journal of Obesity. Researchers from the University of Murcia, in Spain, tracked 420 participants on a 20-week weight-loss program. All followed a Mediterranean lifestyle with lunch being the main meal of the day. Half were “early” lunch eaters, eating before 3 p.m., and half ate later. Over the study, the early lunch eaters lost significantly more weight than those who ate later (and who also tended to skip or eat less at breakfast than the early lunchers), even… read on >

Two very different studies show that dancing is more than just fun. It can keep your mind sharp and your heart healthy. The first was done in the United Kingdom and published in the American Journal of Preventive Medicine. Researchers pooled results from 11 surveys that included a total of 49,000 people. The investigators compared the health effects of walking and dancing, and found that moderate-intensity dancing was associated with a lower risk of dying from heart disease. Note that it took moderate-intensity activity to bring about these results, so if you’re a fan of slow dancing, you’ll need to pick up the pace. The heart-health benefits of dance are likely due to its interval-training-like bouts of high-intensity movement and it being a stress-relieving hobby you can do for life. While many kinds of dance can make for great calorie-burning cardio, a separate study published in Frontiers in Aging Neuroscience and conducted by researchers at a number of U.S. universities found that learning dance choreography can confer cognitive as well as physical benefits. Researchers specifically looked at the effects of learning the steps of a country dance and found this can stimulate a key area of the brain and slow down natural brain aging. Both studies also restated the positive effects that stem from dance as a social activity, a known brain booster. While it’s… read on >

Can sex help improve the health of a Parkinson’s patient? It might — at least for some. So claims a new two-year study that tracked the sexual habits and disease progression among 355 Parkinson’s patients. “This is in line with data showing a close relationship between sexual health and general health, both in healthy individuals and in patients with chronic disease,” said the Italian-British study team, led by Dr. Marina Picillo. She’s an assistant professor at the University of Salerno’s Center for Neurodegenerative Diseases in Salerno, Italy. Picillo and her colleagues concluded that early-stage male patients who are sexually active do experience “milder” disease progression and a less dramatic loss of motor skills and other disease symptoms, compared with those who don’t. But there’s a hitch. The finding only appears to apply to men. Why? The answer is not clear. But one factor may be that the investigation results were skewed, as twice as many men were enrolled as women (238 men versus 117 women). Beyond that, the study authors pointed out that women experience different Parkinson’s symptoms from men. And women “are less prone to talk about sexual and genital issues due to societal attitudes,” wrote Picillo. Even so, she and her research team said the findings warrant the attention of movement disorder specialists, who might view a patient’s sexual history as a tool… read on >

Swimming lessons can lower the risk of drowning, but black kids often miss out on learning this lifesaving skill, a leading pediatricians group says. “Everyone should have the opportunity to learn to swim,” said Dr. Kyle Yasuda, president of the American Academy of Pediatrics (AAP). “This is an essential life skill for children, teens and adults. It’s an important part of the ‘layers of protection’ that families and communities can put in place to protect children and teens around water,” Yasuda said in an AAP news release. Not everyone has the same access to swimming lessons. Historically, black Americans have faced barriers to learning to swim, and black teen boys have the highest drowning risk of any age group, according to the academy. Rates of drowning among children aged 11 to 12 are 10 times higher for black kids than for whites, according to the U.S. Centers for Disease Control and Prevention. According to Dr. Nia Heard-Garris, “This is a problem we can solve.” She is chair of the AAP Section on Minority Health, Equity and Inclusion. “Some communities have created innovative solutions to provide free or low-cost swim lessons, and others have developed culturally sensitive lessons, and lessons for children with developmental disabilities or special health care needs. All children should have access to these potentially lifesaving skills,” Heard-Garris said. In 2017, nearly 1,000… read on >

(HealthDay News) — Dry eye affects millions of adults in the United States, says the National Eye Institute. In a healthy eye, tears keep the surface moist. Without this lubrication, people may feel a stinging, burning or scratchy sensation. The institute mentions potential causes of dry eye: Medications such as antihistamines, antidepressants and decongestants. Conditions such as diabetes or rosacea. Windy, smoky or dry environments. Long periods of screen time. Seasonal allergies. People with symptoms should consult an eye-care professional.

Having “friendly” bacteria in your digestive system is important for good health. They help the body extract nutrients from food, and boost the immune system in the fight against inflammation and many diseases associated with it. Gut microbes do much better with a plant-based diet, according to a study done at the Washington University School of Medicine in Seattle. That’s because plant-based foods “feed” the good bacteria in your digestive system. The researchers also found that a diet of roughly 1,800 calories a day is best, rather than the typical American way of eating, which clocks in closer to 3,000 calories and is linked to excess weight and chronic illnesses. Rather than feeding unhealthy inflammation, plant-based foods help minimize it. Getting more plant-based foods in your daily diet is a great health resolution, and it doesn’t mean that you suddenly have to go vegan. Where to begin? Start with foods that seem to be especially good for the gut, rich in nutrients and the various types of fiber that create healthy bacteria when they reach the colon and/or push out unwanted ones. Bacteria-boosting foods include bananas and blueberries, Jerusalem artichokes, asparagus, leeks, onions, cruciferous vegetables like broccoli, kale, cabbage and cauliflower, polenta (a type of ground corn), all kinds of beans, and fermented foods rich in probiotics, such as pickles, sauerkraut, kimchi, miso and kefir,… read on >

Sweet corn is an irresistible summer veggie and a good source of fiber. Ideally, you want to eat it as soon as possible after it’s picked, but you can store corn for up to one week — keep the husks on and refrigerate in produce bags. There’s nothing quite like biting into fresh corn on the cob, but you can turn this “fruit” of summer from side dish into a main dish. For a do-ahead time saver, prep the corn in advance: Discard the husks, cut off the kernels with a serrated knife, and store the shucked kernels in an airtight container until ready to use. Corn pairs well with superfoods like beans and greens, and lends a naturally sweet taste to recipes like this delicious take on falafel. Corn & Chickpea Falafel 1 15-ounce can chickpeas, drained and well rinsed 2 cups corn kernels 1 cup parsley 4 scallions 1/3 cup all-purpose flour 1 teaspoon baking powder 2 tablespoons tahini paste 1/4 cup olive oil, divided 8 cups baby greens Place the chickpeas in a food processor and pulse until finely chopped, and then transfer to a bowl. Fold in the corn kernels. Chop the parsley and scallions, and add to the bowl. Add in the flour and baking powder. Mix well until a heavy, thick and wet mixture forms, and then stir in… read on >

Do you pump your arms while walking? Keeping your arms straight while walking is much more energy-efficient than walking with bent arms, but arm position doesn’t make much difference when running, a new, small study finds. The study included eight university students — ranging from casual runners to marathoners — who were filmed while they walked and ran with bent and straight arms while on a treadmill. “The hardest thing was running with straight arms,” and all of the participants found the movement strange, said Andrew Yegian, a graduate student at Harvard University. The participants repeated the running and walking tests again two weeks later, but this time breathed through a mask to measure their oxygen consumption. This enabled the researchers to calculate the participants’ energy consumption with their arms in different positions. The results were published online July 9 in the Journal of Experimental Biology. Holding the arms bent while walking increased energy consumption by 11%, proving that walking with straight arms is by far the most energy-efficient option, the study authors said. But there was little difference in energy consumption when having arms straight or bent while running. “We didn’t find any evidence that the energy cost was different between arm postures when running,” Yegian said in a journal news release. He said he had suspected that running with bent arms would be… read on >
