Sibling bullying is under-recognized, study finds

Across the U.S., parents, educators, doctors and other experts have rallied to protect children from bullies. However, bullying by brothers and sisters is often chalked up to normal sibling behavior. Now a new study finds that sibling aggression, like peer aggression, causes mental distress, which can lead to anger, depression and anxiety in the child who is being targeted. The researchers found that 32 percent of the children and adolescents had experienced one type of sibling aggression during the previous year. Further, the study showed that regardless of whether the aggression was mild or severe, bullied kids had significantly worse mental health than children who were not bullied. “There is a natural emotional intensity to sibling relationships,” said lead author Corinna Jenkins Tucker, an associate professor of family studies at the University of New Hampshire. “There is a lot of love, but also the potential for a lot of conflicts.” More from LiveScience The researchers analyzed information from telephone interviews with nearly 3,600 adolescents ages 10 to 17, and with adult caregivers of children 9 and under. Each youngster had at least one sibling under 18 who was living at home. The data were obtained as part of The National Survey of Children's Exposure to Violence, which documents the incidence and prevalence of youngsters' exposure to violence. During the interviews, the researcher asked if the adolescent or child had been bullied by a sibling during the past year. As the researchers defined it, bullying included physical assault, property victimization (such as forcibly taking something a child was wearing, or destroying something belonging to the child), or psychological aggression (such as name-calling, or telling the child he or she wasn't wanted around). In addition, researchers asked the youngsters if they had experienced anger, depression or anxiety during the previous month. Eight percent of the children interviewd had experienced two or more types of sibling bullying duringthe previous year. Children who were even mildly physically assaulted by a sibling had greater mental distress than adolescents who were not assaulted. However, all the kids were similarly affected by the other types of sibling aggression. Tucker said that parents and other adults often downplay sibling aggression. As a result, it's “under-recognized and under-estimated,” she said. “Our work is showing that in some cases, the mental distress associated with sibling aggression is similar to what we see with peer aggression. It is something to be taken seriously.”  Mark E. Feinberg, a research professor at the Prevention Research Center at Penn State University, said “while our society has been working to eliminate bullying, it has not touched the relationship that is most violent — the sibling relationship.” The findings are “are not news to those of us who have been paying attention to sibling relationships,” but because the study involved a large, nationally representative sample, the findings should focusattention on sibling aggression, said Feinberg, who was not involved with the study. “The question then is, what do we do about it?” he said. “Nobody yet has the answer on how to deal with this problem.” According to Tucker, when parents notice bullying, they should step in. “It is an opportunity for parents to act as a mediator, and teach constructive conflict skills,” she said. Parenting programs, Tucker added, should include discussions about sibling bullying as well. “There is a big push now to stop aggression, particularly between peers, and we are suggesting that these programs include a focus on siblings,” she said.

Drinking alcohol to shrink?

Alcohol and your weight have a tricky relationship. So tricky, in fact, that experts have had a tough time nailing down exactly why some women wind up with a beer gut (or butt) while others drink daily and never seem to gain a pound. Here's what we know: Your average drink—beer, wine, martini, pick your poison—is usually a combination of carbs, sugar and ethanol (pure alcohol). When it goes down the hatch, it makes a pit stop at your stomach, where some of the alcohol is absorbed through the lining and into your bloodstream, giving you that initial buzz. The carbs and sugar go the traditional digestive route, while ethanol, a toxin, is diverted to the liver. This is when that innocent little drink starts messing with your internal fat incinerator. Ethanol has no nutritional value, so your body burns it off first. That means any remaining calories in your stomach—whether they're from the margarita or the chips and guacamole you had with it—will likely be stored as fat.  And the more fattening the foods you eat, the easier the calories are to store. (Bear in mind that research published in Physiology & Behavior found that alcohol makes us focus on immediate pleasure and ignore the consequences, which often results in eating junk food.) Unlike protein and carbs, which require some energy for the body to break down and store, fat can directly deposit itself, so those chips are first in line to be plastered to your thighs. MORE: The 3 Biggest Weight Loss Mistakes Still, the situation might not be as bleak as it appears, because the real problem may not be drinking itself, but how often and how hard we hit the bottle. Drink and Shrink? A 2010 study published in the Archives of Internal Medicine may be the best news for booze since the 21st Amendment. Researchers found that women who had one or two alcoholic drinks a day were actually less likely to gain weight than those who shunned the sauce. And they did it while consuming more calories overall (from food and drink) than both heavy drinkers and teetotalers. Short of striking a deal with the devil, how did they manage to pull that off? Researchers believe that the bodies of long-term moderate drinkers somehow adapt to metabolize alcohol differently than heavy or occasional drinkers. They use more energy, burning the calories in the drink—or even more than that—while digesting it, Dr. Lu Wang, the lead researcher of the study and an instructor in medicine at Brigham and Women's Hospital in Boston, said.  Researchers are still working out the specifics of how and why this happens, but they've figured out that for women who drink up to eight ounces of an alcoholic beverage a day, those calories simply don't end up as extra fat. MORE: 15 Ways to Boost Your Metabolism Of course, there's a catch. Women who bank their daily drinks for weekends or girls' nights out don't qualify for the free-calorie plan (and among the 18-to-25 crowd, this “binge” behavior is on the rise, according to a 2009 Addiction study).  “Your body adjusts metabolically to the amount you drink, and when you don't drink regularly, your body can't adjust,” Wang said.  Instead of learning to disregard those nutritionally empty calories, your body automatically stores them—as fat. It's akin to tossing old clothes you don't wear into the back of your closet, only your body doesn't have the good sense to hide the junk. It tends to store the fat front and center, in your belly. MORE: 4 Amazing Abs Exercises Booze Clues Evidence suggests that moderate drinkers also tend to practice healthier habits than teetotalers. If you're used to having three or four drinks every week as part of your diet, you're probably compensating for them with fewer calories elsewhere.  “These women know how to moderate how much they drink, so it makes sense that they'd moderate what they eat as well,” Robert Klesges, a professor of preventive medicine at the University of Tennessee Health Science Center in Memphis, said. The Archives study found that these women also exercise more, which knocks off additional calories. Another thing that helped: The women in the Archives study were served no more than two four-ounce glasses of wine or two 1.5-ounce shots of liquor a day. In real life, you're likely to be handed far more than that by a bartender or waitress—20 to 45 percent more, according to a 2009 study in the journal Alcohol. And we're not much better when left to our own devices.  “Eyeballing the right amount is very difficult,” William C. Kerr, a senior scientist at the Alcohol Research Group in Emeryville, Calif., said. “Most of us don't even know how much we should be shooting for, so overpouring is typical.” MORE: 20 Habits That Make You Fat It's especially easy to overdo it with vino, given that the average wineglass these days looks big enough to hold a school of fish. So a bottle of light beer may be your best bet.  “Unlike wine and mixed drinks, it's portion controlled—the bottle is right there with the calories printed on it,” says Lisa Young, R.D., author of “The Portion Teller Plan.” “It eliminates the guesswork.”source : http://www.foxnews.com/health/2013/06/14/drinking-alcohol-to-shrink/

Newly discovered gene strengthens heart, fights breast tumors

A new study has pinpointed a single gene that appears to both strengthen the heart –  without exercise – and halt the spread of breast cancer. Researchers at Case Western Reserve University found that the gene HEXIM1, discovered in 2012, not only suppressed the spread of breast cancer in mouse models, but also made the mice’s hearts healthier. with respect to enhanced strength and size. Normally, exercise helps to strengthen the heart and increase its size. However, researchers found that when the HEXIM1 gene was re-expressed in adult mouse hearts, their hearts grew in weight and size - without exercise. Researchers say this discovery has the potential to help treat people with cardiovascular disease. “Our Cleveland-based collaborative research teams revealed that increasing HEXIM1 levels brought normal functioning hearts up to an athletic level, which could perhaps stand up to the physical insults of various cardiovascular diseases,” said Michiko Watanabe, professor of pediatrics, genetics, and anatomy at Case Western Reserve School of Medicine and director of Pediatric Cardiology Fellowship Research at Rainbow Babies and Children's Hospital. Common cardiovascular diseases like hypertension and heart failure create a shortage of both oxygen and necessary nutrients in the heart muscles, preventing blood from circulating at a satisfactory rate. This ultimately results in a distended heart, which can continually grow weaker and has the potential to stop at any given moment. However, researchers showed that the artificial enhancement of HEXIM1 led to increased blood vessel growth and enhanced overall functionality of the heart. In essence, HEXIM1 could potentially serve as a therapeutic target for the treatment of heart disease. Researchers also found that HEXIM1 increased the number and density of blood vessels in the heart, decreased the animals’ resting heart rates and allowed the transgenic heart to circulate more blood per heartbeat.  The study also demonstrated that untrained genetically altered mice with the HEXIM1 gene were capable of running twice as long compared to unaltered mice. Lead researcher Monica Montano, associate professor of pharmacology, Case Comprehensive Cancer Center member, and creator of the mice for the heart and breast cancer research, was very proud of the research’s findings. “Our promising discovery reveals the potential for HEXIM1 to kill two birds with one stone – potentially circumventing heart disease as well as cancer, the country's leading causes of death,” Montano stated. The study’s results add to previous findings from the team’s research, which revealed last year that increasing levels of HEXIM1 expression led to the inhibition of breast cancer metastasis. Given the discovery of the gene’s two therapeutic benefits, the researchers are currently developing a more potent version of the drug hexamethylene-bisacetamide, which is meant to enhance HEXIM1 expression. “Many cancer drugs have detrimental effects on the heart,” said Dr. Mukesh K. Jain, professor of medicine and director of Case Cardiovascular Research Institute at Case Western Reserve School of Medicine. “It would be beneficial to have a cancer therapeutic with no adverse effects on the heart and perhaps even enhance its function.” The research was published in the peer-reviewed journal Cardiovascular Research.source : http://www.foxnews.com/health/2013/06/14/newly-discovered-gene-strengthens-heart-fights-breast-tumors/

Major hurdle cleared to diabetes transplants

Efforts to make this treatment possible have been limited by a dearth of insulin-producing beta cells that can be removed from donors after death, and by the stubborn refusal of human beta cells to proliferate in the laboratory after harvesting. The new technique uses a cell conditioning solution originally developed to trigger reproduction of cells from the lining of the intestine. "Until now, there didn’t seem to be a way to reliably make the limited supply of human beta cells proliferate in the laboratory and remain functional," said Michael McDaniel, PhD, professor of pathology and immunology…

Gene variants may predict who will benefit from breast cancer prevention drugs

The work represents a major step toward truly individualized breast cancer prevention in women at high risk for the disease based on their age, family history of breast cancer, and personal medical history. "Our study reveals the first known genetic factors that can help predict which high-risk women should be offered breast cancer prevention treatment and which women should be spared any unnecessary expense and risk from taking these medications," said the study’s lead scientist, James N. Ingle, M.D., professor of oncology at the Mayo Clinic in Rochester, Minn. "We also discovered new information about how the drugs tamoxifen and raloxifene work to prevent breast cancer." Ingle and Mayo-based colleagues in the NIH Pharmacogenomics Research Network (PGRN) conducted the study in collaboration with PGRN-affiliated researchers at the RIKEN Center for Genomic Medicine in Tokyo. …

Bug bites causing allergies? How to avoid dangerous tick bites

As we transition into summer, it is expected that the now infamous lone star tick will continue to spread throughout the United States.  When the lone star tick bites, saliva is injected into the victim that contains a specific sugar known as “alpha gal,” according to research from the University of Virginia. In as little as a few weeks, this appears to cause an antibody surge that can precipitate a full blown allergic reaction after eating red meat, such as beef, pork and/or lamb, but not poultry.   It’s important to be aware of health issues related to tick bites, and of course to plan ahead to reduce the likelihood of giving your favorite host a warm-blooded meal.  That means following some of the suggestions by the CDC: 1. Know your neighborhood.  Find out whether deer or lone star ticks are prevalent in your area. 2. Assess the risk of your activity and the chance of exposure to ticks, i.e. hiking in woods vs. back yard picnics.   3. Know the proper way to apply both DEET and natural based insect/tick repellents, how long they protect and what concentration is appropriate for adequate protection for adults and children.   4. Consider dressing in light clothing making it easier to spot very small ticks. 5. Always due a close inspection and tick check when returning from tick endemic areas. 6. Learn the recommended techniques in removing a tick. 7. Save the recovered tick for analysis by your local department of health, and they can determine the type of tick and whether it may contain the bacteria that causes Lyme disease, for example. So be prepared - and avoid getting “ticked off” this summer!Dr. Clifford Bassett is an adult and pediatric allergy specialist, and diplomat of the American Board of Allergy and Immunology.

Outlawing drugs like marijuana censors science, researchers say

The outlawing of drugs such as cannabis, magic mushrooms and other psychoactive substances amounts to scientific censorship and is hampering research into potentially important medicinal uses, leading scientists argued on Wednesday. Laws and international conventions dating back to the 1960s have set back research in key areas such as consciousness by decades, they argued in the journal Nature Reviews Neuroscience. “The decision to outlaw these drugs was based on their perceived dangers, but in many cases the harms have been overstated,” said David Nutt, a professor of neuropsychopharmacology at Imperial College London. In a statement accompanying the Nature Reviews paper, he said the laws amounted “to the worst case of scientific censorship since the Catholic Church banned the works of Copernicus and Galileo”. “The laws have never been updated despite scientific advances and growing evidence that many of these drugs are relatively safe. And there appears to be no way for the international community to make such changes,” he said. “This hindering of research and therapy is motivated by politics, not science.” Nutt and Leslie King, both former British government drugs advisers, and co-author David Nichols of the University of North Carolina, called for the use of psychoactive drugs in research to be exempted from severe restrictions. “If we adopted a more rational approach to drug regulation, it would empower researchers to make advances in the study of consciousness and brain mechanisms of psychosis, and could lead to major treatment innovations in areas such as depression and PTSD,” Nutt said. Nutt was sacked as a government adviser in 2009 after publicly criticizing the government for ignoring scientific advice on cannabis and ecstasy. He has conducted a small human trial using psilocybin, the psychedelic ingredient in magic mushrooms. His study, using volunteers, suggested the drug had the potential to alleviate severe forms of depression in people who did not respond to other treatments. But in April, Nutt said his plans to conduct the first full clinical trial to explore psilocybin as a treatment had stalled because of stringent rules on the use of illegal drugs in research. The scientists said their call for reform had been endorsed by the British Neuroscience Association and the British Association for Psychopharmacology.source : http://www.foxnews.com/health/2013/06/12/outlawing-drugs-like-marijuana-censors-science-researchers-say/
