Despite new recommendations, women in 40s continue to get routine mammograms at same rate

In 2009, the U.S. Preventive Services Task Force (USPSTF) sifted through the evidence and recommended that while women ages 50-74 should continue to undergo mammograms every two years, those between the ages of 40 and 49 without a family history of breast cancer should discuss the risks and benefits of routine screening mammography with their physicians to make individual decisions. As a result of the altered recommendations, Lauren D. Block, M.D., M.P.H., a clinical fellow in the Division of General Internal Medicine at the Johns Hopkins University School of Medicine, and her colleagues expected to find fewer women in their 40s getting routine mammograms. …

Hysterectomy not tied to heart risk factors, study shows

Despite evidence suggesting that women whose uterus has been removed may be more likely to experience heart troubles, a new study finds that the usual signs of heart disease risk are not more severe in middle-aged women after hysterectomy. After following more than 3,000 women for about 11 years, researchers found that heart risk factors like cholesterol, markers of inflammation and blood pressure were not significantly worse in women in the years following an elective hysterectomy, compared to women who did not have the procedure. “I think it's encouraging to women and clinicians that this is not something they have to worry about if they're considering hysterectomy (in) midlife,” said Karen Matthews, the study's lead author from the University of Pittsburgh. Hysterectomy, the surgical removal of the uterus, is the second most common surgery among U.S. women, after cesarean-section deliveries. Often the procedure is used to remove or prevent cancer, especially among younger women. But many women may elect to have the surgery for other reasons, including to treat painful benign growths in the uterine wall known as fibroids or to staunch heavy bleeding. Hysterectomies can involve removal of the uterus only, or the ovaries as well. Ovary removal in particular has been linked to increased cardiovascular risk because it takes away the main source of estrogen in a woman's body and plunges her abruptly into menopause. Even the gradual decline of estrogen following natural menopause has been linked to women's increased heart risks, so researchers have investigated whether hysterectomy raises those risks. But studies of the connection have produced mixed results. For the new study, Matthews and her colleagues used data from the Study of Women's Health Across the Nation, which followed a large, multiethnic group for more than a decade to understand the experience of American women during and after menopause. The 1,952 women included in the study were between 42 and 52 years old and not yet in menopause when tracking began. They were followed from 1996 through 2008, receiving annual checkups that recorded information about their health, surgeries and whether or not they had started menopause. Specifically, the researchers looked at physical measurements that are markers for heart and cardiovascular disease. They included various components of cholesterol, blood pressure, blood clotting factors and molecules that are signals of inflammation. Overall, the researchers report in the Journal of the American College of Cardiology that none of those measurements in the 183 women who chose to have their uterus removed - with or without their ovaries - were significantly worse, compared to the 1,769 women who went through menopause naturally. Matthews said their findings apply to women who are finished having children, in their forties and are considering a hysterectomy to help with excessive bleeding or other factors that cause a quality of life problem. She said they couldn't make a conclusion for women who need to have their uterus and ovaries removed because of cancer. “Our study really couldn't examine that question because we had too few women who had gynecological cancers, and the equation changes when you have gynecological cancer,” said Matthews. But Dr. JoAnn Manson, who has researched women's health after hysterectomy but was not involved in the new study, suggested the results don't mean that women who have hysterectomies are in the clear, because past studies only saw a difference in heart risks after 10 to 15 years. Manson, who is chief of preventive medicine at Brigham and Women's Hospital in Boston, told Reuters Health that the abrupt transition to menopause after a hysterectomy may only reverberate years later because “atherosclerosis takes a while to develop… That seems to take up to 10 and 15 years for clear differences to emerge.” For that reason, “This isn't totally surprising that there wasn't a difference in risk factors during the follow up period,” Manson said. Matthews said that's one potential explanation for why their results differ from previous studies, but she said there could be other reasons, including that modern women are somehow different from women included in past research. “It may be that it's emerging much later, but I would be surprised,” Matthews said.source : http://www.foxnews.com/health/2013/05/15/hysterectomy-not-tied-to-heart-risk-factors-study-shows/

Marijuana-like compound could lead to first-ever medication for PTSD

The life of an individual suffering from post-traumatic stress disorder (PTSD) is often a debilitating one, as patients are frequently plagued by intense nightmares, flashbacks and emotional instability.    There are a number of psychotherapeutic treatments and cognitive behavioral therapy options to aid sufferers of PTSD, but these interventions are not always available to patients.  And while medications tend to be the first line of defense for these individuals, no pharmaceutical treatments have been developed yet to specifically target PTSD. But now, new research may help dramatically change the course of treatment for PTSD patients.  In the first study of its kind, researchers at New York University Langone Medical Center have utilized brain imaging technology to highlight a connection between the number of cannabinoid receptors in the brain and PTSD.  Cannabinoid receptors, known as CB1 receptors, are activated in the brain when a person uses cannabis, which can lead to impaired memory and reduced anxiety. The researchers’ findings pave the way for the development of the first every medication designed explicitly to treat trauma – something, they say, is desperately needed. “The first line of treatment (for PTSD patients) is selective serotonin reuptake inhibitors, which is a class of medication generally used with good effects in people with depression,” lead author Dr. Alexander Neumeister, director of the molecular imaging program in the departments of psychiatry and radiology at NYU School of Medicine, told FoxNews.com.   “These medications do not really do the job for people with PTSD, so clinicians use anything else that is legally available on the market.  They often use different classes of medications developed for things like depression, schizophrenia, or bipolar disorder, and overall there’s consensus that these do not work.” Affecting nearly 8 million Americans each year, PTSD is an anxiety disorder that is developed after an individual experiences a dangerous or painful life event – such as a sexual assault, a tragic accident, surviving an act of extreme violence or the experience of fighting in a war.  Of the 1.7 million American men and women in the military who have served in Iraq and Afghanistan, approximately 20 percent have been diagnosed with PTSD. During the past decade, Neumeister and his team have studied the impact PTSD has on the brain’s physiology and have found that exposure to severe trauma can considerably alter how the brain functions.  With this knowledge in mind, the researchers decided to examine CB1 receptors in the brain due to a common trend observed among PTSD patients: Marijuana use.  In an attempt to cope with their symptoms, many PTSD patients end up using and abusing cannabis, which helps to temporarily relieve them of their incapacitating episodes. According to Neumeister, PTSD patients often report that smoking marijuana works better for them than any other legal medication, leading the researchers to believe that the manipulation of CB1 receptors in the brain may have a beneficial impact on trauma symptoms. “About 8 years ago, the first animal study was published showing that everybody has endogenous cannabinoids, or endocannabinoids, in the brain – meaning this substance is in the brain of every person,” Neumeister said, noting that endocannabinoids act like cannabis, binding to CB1 receptors to help extinguish traumatic memories. “Animal studies have suggested that increasing cannabinoids in the brain helps them to forget painful events and form new memories, so they start to learn to digest what they went through and get over it.  We thought this may be relevant to PTSD.” To test this idea, the researchers performed positron emission tomography (PET) imaging on the brains of 60 participants who had been divided into three groups – those with PTSD, those with a history of trauma, but no PTSD, and those with no history of trauma or PTSD.  Each participant was injected with a harmless radioactive tracer, which was designed to travel to the CB1 receptors in the brain and illuminate them under the PET scan. The images revealed what the researchers had expected.  The individuals with PTSD had higher levels of CB1 receptors in areas of the brain associated with fear and anxiety than the volunteers without PTSD.  Those with PTSD also had lower levels of the neurotransmitter anandamide, an endocannabinoid that binds to CB1.  Neumeister explained that lower levels of anandamide prompts the brain to compensate by increasing the number of CB1 receptors, resulting in an imbalanced endocannibinoid system. Because CB1 receptors help regulate mood and anxiety, the scientists advised against creating medications to destroy them in the brain, as that would lead to depression.  Instead, Neumeister said their PTSD medication would rely on promoting CB1 equilibrium. “We want to increase the concentration of these endocannabinoids,” Neumeister said.  “So we are currently working on the methods to do this, and we have developed a compound that is able to increase the concentration of endocannabioniods without attacking the receptors. It helps restore a normal balance of this chemical in the brains of those with PTSD.” Neumeister claims the compound is very safe and does not come with the added health problems caused by chronic marijuana use. “Very soon, we will be able to start clinical trial of this medication in people,” Neumeister said.  “It’s the first medication developed for people with PTSD, so I hope that it will open up a new generation of treatment for people.” The study, funded by the National Institutes of Health, was published in the journal Molecular Psychiatry.source : http://www.foxnews.com/health/2013/05/14/marijuana-like-compound-could-lead-to-first-ever-medication-for-ptsd/

7 tips to stop your summer weight obsession

With summer approaching, you might spend time preparing for swimsuit season. Rather than dreading this time of year, here are some tips to begin to practice appreciating your body so you can enjoy the sun. 1.   Accept your weight. You may think the more you fight your weight, the more you’ll succeed in losing weight. This simply isn’t true. Accepting doesn’t mean not taking steps towards changing your weight, it means not letting your weight hold you back from your life. If you’re waiting until you lose weight to apply for jobs or start online dating, your weight is going to weigh you down. Do what you care about now. 2.   Go on a weight-talk diet. It’s tempting to ask your friends if you’ve lost weight, ask them about what they’re doing to lose weight, or discuss together who you think needs to lose weight. There is way more to talk about than weight. When the topic comes up, practice moving the topic to something more fun! 3.   Only visit your scale once a week. Weight fluctuates within six pounds on any given day depending of what you’ve had to eat and drink. Rather than checking your weight compulsively and worrying you gained weight after you ate a big meal, only weigh yourself once a week and make it at a set time, like 8 a.m. Monday mornings. 4.   Go shopping.   If you are in between sizes and your clothes are uncomfortably snug, you will constantly remember you’ve gained weight and eat to cope with this negative feeling. I’ve seen a lot of clients feel better and eat better by wearing clothes that fit. Buying clothes your size is not giving up, it’s being practical. 5. If you compare, be fair. It’s weirdly tempting to compare yourself to the thinnest person you see or a celebrity you admire. Yet, this is so unfair and sets you up to feel inferior and obsess further. Rather than compare yourself to someone remarkably thin or fit, compare yourself to every eighth person you see. Better yet, don’t compare. When you notice you’re judging yourself in comparison to someone else, remind yourself that’s a judgment and let go. 6. Eat regular meals. Many people who struggle with obsessing around food get caught in this cycle: Overeat --> limit what they eat to make up for the indulgence --> feel hungry --> overeat. Rather than get caught in this cycle of feeling too full then feeling too hungry, eat three meals and two snacks. If you ate too much for breakfast, eat a normal lunch; this will prevent you from skimping on lunch and splurging on dinner. 7. Relax your face when you look in the mirror. One of the ways to improve your body image and stop engaging in negative thoughts about your appearance is to relax your face and body when you look in the mirror. There’s a facial feedback loop and the facial expressions we make solidify how we feel. Research on Botox shows people whose facial muscles are paralyzed experience less intense emotions. One way to relax your face is to ever so slightly lift the upper corners of your lips. If you don’t want your daughter to learn to grimace in front of the mirror, become a role model for self-acceptance.Jennifer Taitz & is a licensed clinical psychologist based in New York City.

Is creatine safe for teens?

Even if you’re not a body builder, you’ve probably heard of creatine -- and those who use it, swear by it. But no one should put supplements into their body without weighing the risks and benefits. We recently received this question from a concerned viewer: Dear Dr. Manny, My 17-year-old son is interested in taking creatine. Is it safe? Thanks, Linda Creatine is a combination of amino acids produced naturally in the body by the liver, kidneys and pancreas. It can also be found in the protein-rich foods we eat, like meat and fish. It reduces muscle fatigue by transporting extra energy to the body’s cells, and causes water weight gain – which can make muscles appear larger. “Creatine supplementation has not been adequately studied in those under 18 years old,” said Elizabeth DeRobertis, a registered dietician and nutritionist. “So for that reason, it is not recommended that your son try creatine. Once he turns 18, DeRobertis added, it’s important that he know a few things: 1. Creatine has been found to be effective in short-duration, high-intensity exercises, like sprinting. 2. He should be involved in competitive athletics if he does decide to try creatine, and he should let his coach know, his health care professional know, and of course, his parents know. 3. It’s also important that he drink enough water during the day, because creatine may contribute to dehydration – so he should drink at least 64 ounces of water every day. 4. He should not combine creatine with any other supplement, especially those containing caffeine or ephedra. As always, it’s important to talk to your doctor before making any diet or lifestyle changes. Do you have a question for Dr. Manny?

Your 5 worst gluten-free mistakes

After experiencing some wacky symptoms, I was recently tested for celiac disease, and while the report came back negative, I've noticed that I do feel better when I avoid gluten. Many of my clients are in the same boat, but others seek me out after going gluten free and feeling worse, or even gaining weight, which seems to be increasingly common.  The truth is, navigating the gluten-free landscape can be pretty darn tricky. Here are five common missteps I see, and how to resolve them. Not 'getting' gluten One client recently said to me, “I'm not really sure what gluten is, but I know it's bad, right?” I think a lot of people are a little in the dark about the issue at large, and it is complicated, but in a nutshell, here's what you need to know: gluten is a type of protein naturally found in wheat (including spelt, kamut, farro, and bulgur) and other grains, like barley and rye. In people who have celiac disease, consuming even small amounts of gluten triggers unwelcome symptoms, including belly pain and bloating. This happens because gluten causes the immune system to damage or destroy villi, the tiny, fingerlike structures that line the small intestine like a microscopic plush carpet. Healthy villi absorb nutrients through the intestinal wall into the bloodstream, so when they become damaged, chronic malnutrition occurs, which is typically accompanied by weight loss and exhaustion. Other symptoms may include bone or joint pain, depression, and skin problems. In people with this diagnosis, the only way to reverse the damage, and the accompanying symptoms, is to completely avoid gluten. People like me, who test negative for celiac disease, may be experiencing a condition called gluten intolerance, or gluten sensitivity, which means that while not celiac, consuming gluten causes bothersome side effects, which can include flu-like feelings, bloating, and other gastrointestinal problems, mental fogginess, and fatigue. Unfortunately, there is no real test for gluten sensitivity at this time, and the symptoms may be related to other issues, including stress (who doesn't have that?!), which makes it a not-so-black-and-white issue. Health.com: Will a Gluten-Free Diet Improve Your Health? Confusing 'gluten free' with 'wheat free' or refined grains As I noted above, gluten isn't only found in wheat. I've heard numerous people say they eat gluten free, but all they've really done is replace foods like white bread with hearty whole grain versions, which may include spelt (in the wheat family), and rye (which, while not wheat, also contains gluten). If you don't have celiac disease or gluten intolerance, these swaps may make you feel great, and lead to weight loss, because trading refined grains for whole grains ups your intake of <a href=”http://www.health.com/health/gallery/0,,20553010,00.html”>fiber</a>, boosts satiety, so you feel fuller longer, and better regulates blood sugar and insulin levels. These are all good things, but, in this case, totally unrelated to gluten. Health.com: 15 Gluten-Free Recipes Thinking gluten free equals weight loss You may have seen a friend, co-worker, or celebrity suddenly slim down after proclaiming to give up gluten. And while going gluten free may absolutely lead to dropping a dress size (or more), the weight loss is generally caused by giving up foods that contain gluten, which are loaded with dense amounts of refined carbs, like bagels, pasta, crackers, pretzels, and baked goods. Axing these foods altogether, or replaced them with more veggies and healthy gluten-free whole grains, like quinoa and wild rice, automatically cuts excess carbs (which may have been feeding fat cells), ups fiber and nutrients, and results in soaring energy. However, going gluten free can also lead to weight gain. Health.com: Best Superfoods for Weight Loss Loading up on gluten-free junk food Because gluten free has exploded in popularity, there are dozens of gluten-free options in markets these days, including carb-laden (but gluten free) versions of… bagels, pasta, crackers, pretzels, and baked goods! One popular brand of gluten free cookies pack 60 calories each, more than a “regular” sandwich cookie. And some gluten-free foods are made with refined gluten-free grains, which have been stripped of their fiber and nutrients, like white rice. The bottom line is, simply going gluten free doesn't guarantee the loss of pounds and inches—quality and quantity still matter most. Health.com: Are You Making These Dieting Mistakes? Ignoring the rest of your diet In addition to quality and quantity, balance is critical for feeling well and achieving weight loss. I've seen people trade white pasta for healthy whole grains like quinoa or wild rice, but still eat portions that are far too large, and therefore not see weight loss results. Others believe it's OK to eat unlimited amounts of healthy gluten-free foods, like fruit and nuts. But sadly, any time you eat more than your body can use or burn, even from healthy foods, you create surpluses, which get shuttled straight to your body's storage units—fat cells. If you have celiac disease (get tested if you suspect you do, but you're not sure), you absolutely must avoid gluten, and it's important to note that it lurks in many products, from salad dressings and seasoning mixes, to vitamins, and even lip balm, so eliminating it completely is a big commitment. And if you think you may be gluten intolerant, try to avoid gluten, and monitor your how you feel. But in either case, the single most important thing you can do is to strive for a healthy, balanced, whole foods diet, the true keys to both optimal health and weight loss.

Leap in leukemia treatment

CLL lives both in the blood in circulation, and in lymph nodes and bone marrow. The former is relatively easy to kill, but the disease recurs because of resistant CLL cells in the lymph nodes and bone marrow. The researchers found an innovative drug combination that targets the stubborn CLL cells. "We have been studying the mechanism in the cancer cells that causes the resistance to treatment," says Alan Eastman, the senior researcher on the team and a professor of pharmacology and toxicology at the Geisel School of Medicine at Dartmouth, "and that in turn, led us to find drugs that target the resistance." Eastman led the team at Dartmouth-Hitchcock’s Norris Cotton Cancer Center that also included Ryan Soderquist, Darcy Bates, and Alexey Danilov. …

Dr. Manny: Let the Gosnell verdict be a warning to others

The Philadelphia doctor accused of performing illegal, late-term abortions in his filthy clinic has been found guilty of first-degree murder in the deaths of three babies. Dr. Kermit Gosnell was also found guilty of involuntary manslaughter in the overdose death of one of his patients, but acquitted in the charge of murder in the death of a fourth baby. While the defense had argued there were no live births at the clinic, prosecutors say 72-year-old Gosnell delivered the living babies before having their spines severed with scissors to kill them. They say the baby whose death he was cleared in let out a soft whimper before Gosnell cut its neck, according to the Associated Press. Prosecutors are seeking the death penalty. So let this verdict be a warning to others. I applaud the decision of the jury in their conviction of Gosnell of first-degree murder in at least three of these tragic deaths. As a practicing high-risk OB-GYN who delivers many premature babies, I feel that what went on in that clinic was truly horrific, and deserves the highest degree of punishment possible. Let this also be a warning to city and state officials who failed to do their jobs of checking up on this death clinic, knowing full well that they have a moral and ethical responsibility to respond when citizens file complaints. Gosnell’s clinic was hardly ever inspected, and those city and state officials should bear a degree of guilt in allowing this doctor to practice the way he did. In the aftermath of this despicable case, I hope that political pundits don’t spin this story into an issue purely of abortion, but take the opportunity to discuss how to improve women’s health services in this country.source : http://www.foxnews.com/health/2013/05/13/dr-manny-let-gosnell-verdict-be-warning-to-others/

Agent orange exposure linked to life-threatening prostate cancer

The herbicide Agent Orange was heavily used during the Vietnam War era and was often contaminated with dioxin, a dangerous toxin and potential carcinogen. Prior research suggests that exposure to Agent Orange may increase men’s risk of developing prostate cancer, but it is unclear whether it specifically increases their risk of developing lethal forms of the disease…
