[CC] 00:21:34 In tonight's Family HealthWatch, a breakthrough that helps us understand why some people need less sleep than others. John McKenzie has that story. Ah, sleep. Eight to eight and a half hours a night. It's what most people need. But for millions of Americans, just getting that much sleep means you must be dreaming...Surveys show 30 percent of Americans sleep six hours a night or less, and that alone can increase risks for cardiovascular disease, obesity and memory problems. So, imagine the excitement of discovering a gene that controls how much sleep people need, a gene that allows people to sleep just six hours a night and awake perfectly refreshed. Dr. Sean Caples from the Mayo Clinic says, "We've known for some time there is a subset of the population who can function well on less than six hours of sleep. We know now there is a potential biological basis for that." Researchers suspect fewer than five percent of people have this genetic mutation making them short sleepers. But at least now there is a target for one day creating a new type of medication. Dr. Allan Pack from the University of Pennsylvania School of Medicine says, " The goal here is turning an eight-hour sleeper to somebody who can sleep less than six hours with no adverse consequences and thereby increase their productivity." Raising the question: just what would you do if all you needed was six hours a night?... Sleep less and look good? Now that's asking a lot. 00:24:34

00:11:39 Depression might be something that may or may not be affecting you. We've brought some folks in who are going to try and help us deal with these issues and talk about the new Center for Depression at the University of Louisville...University of Louisville psychiatrist Dr. Alan Tasman says, "...We're even happier that we've been invited to be one of the founding members of a national network of depression centers. We're in company with such places as Harvard, Stanford, the University of Pennsylvania and the University of Michigan. This will allow us to do an even better job of providing cutting-edge treatments, research and education for our community."... 00:18:30

[CC] 00:21:41 The medical advice for women who undergo mastectomies may soon include pumping iron. For years they've been advised to limit how much lifting they do or they might risk developing lymphedema, a painful swelling of the arm. Now there's more evidence that weight lifting can actually reduce those symptoms. Catherine Smits, the Penn researcher who led the study, says weight lifting also helps breast cancer survivors regain their confidence and their quality of life. 00:24:41

[CC] 00:44:14 A new stance on weight training for breast cancer survivors. Researchers now say it could help during recovery. For decades, doctors have warned that lifting weights or heavy groceries could cause painful arm swelling. Now researchers say the weight may actually prevent problems. Channel 11 News reporter Jodine Costanzo explains. Rosy is a breast cancer survivor who, like most women have also had lymph nodes removed, wears compression garments to control lymphedema or swelling in her arm and hands. " If I don't wear the glove as well, then for some reason all the swelling will go to my hands." For years, doctors have warned women not to lift weights or anything heavy because it can cause or worsen the painful condition, but a new study finds that weight training can prevent it. " They felt that this might be related to the fact that exercise promoted more lymphatic flow out of the arm." A GH breast surgeon Dr. Thomas Julian told me the findings are significant and could mean greater quality of life. The study was done at the University of Pennsylvania and involved 141 survivors who were put on a weight-lifting program for one year. They reported less swelling and better strength. Dr. Julian warns patients to ask their physician if they're a good candidate for weight training. "It doesn't mean that one has to lift 100 pounds of weight. You can do very well with anywhere from 5 to 10 pounds."... 00:47:14

[CC] 00:21:26 We have a breakthrough in understanding one of life's mysteries. Why do some people need very little sleep? It turns out it has nothing to do with caffeinated drinks or fluffy pillows. Scientists have discovered some people are genetically programmed to get by on a little bit of shuteye. Here's John McKenzie with tonight's medical report. Ah, sleep. Eight to eight and a half hours a night. It's what most people need.

[CC] 00:52:30 In HealthCheck this morning, around the world the pharmaceutical injury keeps working on new medicines for the market, but some doctors are finding the best healing agents are already inside the body. Health reporter and registered nurse Ali Gorman explains. The road to recovery for Brian Schneider has been a long one and it's not done yet. In April, 2008, the police officer was putting his motorcycle into formation for a routine escort when his bike slipped out from under him. " I tried to recover and bring it back up and it was sliding out and I just heard an amazing snap." Brian's lower left leg was not just broken; the bone was split lengthwise. Doctors set it, but weeks later when it wasn't healing, he turned to Dr. Samir Mehta of the University of Pennsylvania . Dr. Mehta is using a cutting-edge treatment called Platelet Rich Plasma or PRP. It's made from a patient's own blood. " It takes what's in the blood -- the natural nutrients in the blood -- and concentrates them." With a blood substitute, he shows us how three tablespoons of blood is specially filtered to get the concentrate. What's left is two teaspoons of n utrient-packed plasma. "This has between 25 and 30 growth factors in it." Brian had his blood drawn, it was filtered and then the concentrated plasma was reinjected into his fracture. "His healing response once we applied this was dramatic. It was absolutely dramatic." Now that the split is healed, Brian is focusing on regaining strength and agility so he can go back to the highway patrol... 00:55:30

[CC] 00:25:17 In today's 4 Your Health, breast cancer survivors can help lessen the pain of severe swelling in their arms and hands by lifting weights. Researchers at the University of Pennsylvania School of Medicine looked at just over 140 people with lymphedema. Half were assigned to a weightlifting group who took part in twice-weekly, 90-minute exercise classes for thirteen weeks. Women in the weightlifting group had a reduction in symptoms compared to ones who did not. Scientists believe the controlled weightlifting program may offer protection by boosting strength in those limbs affected by the lymphedema. 00:28:17

[CC] 00:09:09 Hitting the gym for some weight training may help breast cancer patients recover after surgery. Many of these women suffer from lymphedema, a condition that causes swelling of the arms and hands that can be debilitating and often incurable. Researchers at the University of Pennsylvania found when women did careful weight training, they reported less symptoms of lymphedema after one year than women who did not lift weights. 00:10:46

[CC] 00:21:24 Also in this morning's medical report, nearly a quarter of breast cancer survivors suffer from painful swelling of the limbs known as lymphedema. In the past doctors worried that heavy lifting might aggravate that swelling, but new research shows that moderate weight lifting might actually help treat this condition. Dr. Tim Johnson reports. For the over 2. 4 million breast cancer survivors in the United States, swelling and discomfort of the limbs after surgery that removes lymph nodes or radiation to the nodes can be a chronic and incurable problem. The swelling, known as lymphedema, affects as many as a quarter of breast cancer survivors. For years it was thought that overexertion would aggravate this condition, and doctors cautioned patients against using the affected limb for things such as picking up children or carrying grocery bags. However, new research from the University of Pennsylvania shows that moderate weight lifting may actually lessen the severity of this condition. After following patients for a year, the study found that weight lifting twice a week increased the strength and mobility of the affected limbs and decreased limb discomfort. Researchers hope that in the future, weight-lifting interventions like these will help patients manage their lymphedema, allowing them to return to normal activity. 00:24:24
