(HealthDay News) — Buyer beware: When it comes to testosterone supplements, men should know a new study finds there is precious little evidence to support claims they will boost testosterone levels, sex drive, strength and overall energy. To come to this conclusion, the researchers first broke down 50 testosterone supplements into their component parts. The investigators then searched through a comprehensive scientific publication database for any solid proof that the supplements can do what the companies who make them say they can do. But only 12% of the products contained any ingredient shown to provide some testosterone-related benefit in human trials. And nearly half (48%) contained ingredients that studies found could have negative impacts. “In general, I’m not anti-supplements,” noted study author Dr. Mary Samplaski. “I have a lot of patients who take them. But the FDA [U.S. Food and Drug Administration] says very clearly that these products should not claim to treat medical conditions. And 90% of these testosterone supplements do make such claims. So I was just really curious what the scientific support was for the claims being made.” Samplaski said, “What we found is that in the vast majority of cases there was no evidence to show that any of the ingredients in these testosterone supplements were effective in any way.” The upshot, she said, is that “people should understand that just… read on >

When men with prostate cancer have to take drugs that block the testosterone fueling their tumors, they can suffer a host of side effects that include impotence, bone loss, heart trouble and obesity. But new research uncovers yet another possible downside to the treatment: These men may be at greater risk for dementia. For any type of dementia, that risk increased 17%; for Alzheimer’s disease, it increased 23%, the researchers said. Common side effects of so-called androgen-deprivation therapy include hot flashes, unstable mood, trouble sleeping, headaches, high blood sugar, allergic reactions and impotence. “Androgen-deprivation therapy may not only cause physical changes — such as osteoporosis, cardiovascular disease or obesity — but may also cause changes in cognition,” said researcher Dr. Karl Tully, a research fellow at Brigham and Women’s Hospital in Boston. But Tully cautioned that this study cannot prove that such hormone therapy caused dementia, only that the two are associated. The investigators also found that men on this type of therapy had a 10% greater risk of seeking psychiatric services. The risk for dementia increased as the length of therapy increased, the researchers noted. Men on androgen-deprivation therapy for six months had a 25% increased risk for any kind of dementia and a 37% increased risk for Alzheimer’s, the findings showed. Being on hormone therapy longer than six months increased the risk for… read on >

Many children deal with chronic health issues — but it doesn’t mean they can’t enjoy life as much as other kids, a new study finds. Researchers found that among more than 1,200 5- to 9-year-olds, those with some of the most common childhood ills were no less happy with their lives than other kids. They said the findings highlight an important point: Kids aren’t “defined” by their medical issues. “This can help broaden our perspective of what ‘health’ is,” said lead researcher Courtney Blackwell, a research assistant professor at Northwestern University Feinberg School of Medicine in Chicago. “Just because a child has a medical condition,” she said, “that doesn’t mean they’re ‘unhealthy.’ “ The caveat, Blackwell said, is that the study focused on kids with certain common conditions, such as asthma, attention deficit hyperactivity disorder (ADHD) and digestive disorders. It did not include kids with more debilitating diseases that require intense care. If it had, the findings would probably be different, according to Rose Alvarez-Salvat, a child psychologist at Nicklaus Children’s Hospital in Miami. She was not involved with the research, but reviewed the study. Alvarez-Salvat works with kids who have medical conditions like type 1 diabetes, cystic fibrosis, cancer and hemophilia. Those complex disorders, which require daily management, can lead to anxiety and depression for some kids, she said. “They have a very different… read on >

A fainting-related fall that caused nerve damage in his right hand could explain why Leonardo da Vinci’s painting skills declined later in life, a new paper suggests. The report, published as the world marks the 500th anniversary of the artist’s death, contradicts the common belief that da Vinci’s difficulties stemmed from a stroke. To arrive at that conclusion, the report authors compared a drawing of an elderly da Vinci with an engraving of the artist and inventor when he was younger. They also studied a biography of da Vinci. The drawing shows da Vinci’s right arm in folds of clothing as if in a bandage, with his right hand suspended in a stiff, contracted position, according to the paper published May 3 in the Journal of the Royal Society of Medicine. “Rather than depicting the typical clenched hand seen in post-stroke muscular spasticity, the picture suggests an alternative diagnosis such as ulnar palsy, commonly known as claw hand,” study co-author Dr. Davide Lazzeri said in a journal news release. Lazzeri is a plastic surgeon at the Villa Salaria Clinic in Rome. Based on the drawings, he said it’s likely that the ulnar palsy was caused by injury to the right limb when da Vinci fell after fainting. The ulnar nerve runs from the shoulder to little finger. It manages nearly all of the hand muscles… read on >

(HealthDay News) — Visiting a gynecologist is important for women to maintain reproductive and sexual health. Most females should begin seeing a gynecologist at the age of 21, or earlier if they are sexually active, says the University of California at Santa Barbara. Women should expect the following at a gynecologist visit: Taking basic measurements, such as weight and blood pressure. Being asked questions about sexual history and menstrual cycles. Getting a physical examination of the breasts and genitals. Feelings of anxiety are normal, but doctors encourage patients not to worry. These exams are common procedures for doctors, and are typically quick and painless, the school says.

You know the value of exercise for maintaining good health and managing chronic conditions like arthritis, but you also know how hard it is to fit daily workouts into a busy schedule to meet weekly minimums. As an alternative, many people try to cram in a week’s worth of fitness on the weekends. While this approach has been met with skepticism in the past (along with worry about injuries), new research shows that you can get exercise’s health benefits this way. A British study published in JAMA Internal Medicine says there’s no reason to abandon exercise completely if you can’t do it during the work week. Packing exercise into your weekend is actually a viable option. Based on surveys from 63,000 people, any exercise is better than none. Researchers found that people who exercise at a high rate on weekends — getting in the recommended 150 minutes of moderate exercise or 75 minutes of vigorous activity — had about 30% lower risk of early death than people who don’t exercise at all. Another interesting finding: People who exercise more often but for shorter blocks of time can also lower their risk for chronic conditions — yes, even if they fail to total 150 minutes a week. The bottom line? Get up and move whenever you can. Note: If you aren’t in shape, get your doctor’s… read on >

“Get your head in the game!” Coaches say it to players all the time to get them to focus. The same advice can help you be more enthusiastic about your workouts. Here are five ideas: 1. Set both short-term and long-term goals based on your current abilities. Celebrate each one as you reach it and then re-set it. According to the American Council on Exercise, a goal should meet five different criteria to be effective. Make sure each goal is: Specific: You should be able to articulate it in one simple sentence. Measurable: The goal should be something you can see, like an amount of weight lost or duration of a workout. Attainable: The goal should represent a challenge to you, but not be impossible to reach. Relevant: It should be important to you and your life. Time-Bound: The time you allot to reach the goal shouldn’t be open-ended, which could lead to procrastination. Set a reasonable time period for achieving it. 2. Identify what type of pre-exercise prep gets you psyched, such as quiet focused breathing or loud pulsing music. 3. Develop and repeat a mantra, an uplifting statement of what you know you can do. This will help you develop a positive attitude and have an unshakable belief in yourself. It will naturally get stronger as you reach goals. 4. Practice mental toughness.… read on >

Up all night, stressing out, feeling pressured. Cramming for college finals can bring all that, plus have students reaching for fatty, sugary foods, a new study suggests. “Stress has long been implicated in poor diet. People tend to report overeating and comfort eating foods high in fat, sugar and calories in times of stress,” said study leader Nathalie Michels, from Ghent University, in Belgium. “Our findings looking at the eating habits of students during exam periods confirm this stress-induced dietary deterioration hypothesis,” Michels added. For the study, her team looked at the responses of 232 students at universities in Belgium who completed an anonymous online survey. The participants completed the survey before and after a month-long examination period in 2017. The students were asked about their stress levels and changes in their eating habits. During the exam period, students were less likely to follow a healthy diet, and only one-quarter of them met the World Health Organization-recommended intake of 400 grams of fruit and vegetables a day. The researchers also found that students with higher levels of stress tended to snack more often. The study was presented this week at the European Congress on Obesity in Glasgow, Scotland. Such research should be considered preliminary until published in a peer-reviewed journal. “A healthy diet is needed for optimal academic and mental performance. Unfortunately, our findings suggest… read on >
