iStockphoto/Thinkstock(NEW YORK) -- One more worry in the country's obesity crisis: a new documentary highlights the perils of extra pounds during pregnancy.
The TLC special, Obese & Expecting, follows four obese women through complicated pregnancies and painful deliveries that put mom and baby at risk.
"We know that obesity during pregnancy increases the risk of diabetes and preeclampsia," said Dr. Marjorie Greenfield, chief of obstetrics and gynecology at University Hospitals Case Medical Center in Cleveland. "And when the mom is big, the baby can be big, raising the risk of birth injury and C-section."
A scene from the documentary shows doctors struggling to give one woman an epidural through the fat in her back.
"We spent 45 minutes attempting to put the spinal in," said Dr. Charles Hux, a New Jersey OB/GYN featured in the documentary. "With so many layers of fat, it's difficult to be certain that the needle went into the exact space it should go in."
After several tries, the team gave up, deciding instead to give the woman a general anesthetic and a C-section.
"Going to sleep carries significant risks, even for a slim pregnant woman," said Greenfield, calling the decision a last resort. "And the risk goes up significantly in a woman who's overweight."
Studies suggest nearly half of U.S. women who are of child-bearing age are obese, a problem that weighs heavily on doctors.
"It's harder to provide excellent care to someone who's obese because a lot of things we do are not as accurate," said Greenfield, explaining how ultrasounds and other tests to gauge the baby's growth can be skewed by the mother's fat. "It's also harder to feel the position of the baby."
That fat, and the fact that obesity can cause irregular periods, also means women might not realize they're pregnant.
"If you don't know you're pregnant, you might not avoid things that are toxic, like alcohol, smoking and certain medications," said Greenfield, adding that prenatal vitamins are also important. "And a lot of what we do in prenatal care depends on knowing exactly how far along a woman is. If you don't have a sense of gestational age, it's harder to provide the right care."
Obesity has also forced hospitals to adapt, adding delivery tables that can be made wider and hold up to 600 pounds, Greenfield said.
"The old tables only went up to 450 pounds," she said. "That's just not realistic anymore."
Weight gain during pregnancy is normal. But obese women should gain no more than 15 pounds, roughly half the amount recommended for women of normal weight.
"For someone with bad eating habits, that's going to be really hard," said Greenfield, describing how pregnancy cravings and the "eating for two" mentality can conspire to pack on the pounds. "Lifestyle change is always hard. But during pregnancy, I think women are more motivated to do it for themselves and their baby."
Obese & Expecting premiered Thursday night at 9 p.m. on TLC.
iStockphoto/Thinkstock(WASHINGTON) -- The U.S. Food and Drug Administration is investigating the antibiotic azithromycin, commonly known as Z-Pak, after a study linked the drug to an increased risk of death.
The study, published Wednesday in the New England Journal of Medicine, found patients prescribed Z-Pak were more likely to die than those prescribed amoxicillin, another antibiotic. The results were especially pronounced for those who died of heart attacks, strokes, sudden cardiac death and other cardiovascular causes.
Last year, doctors wrote 55.3 million prescriptions for Z-Pak, according to IMS Health. Like the popular antibiotic amoxicillin, azithromycin is commonly prescribed to help fight off bacterial infections. But while they are often prescribed for similar conditions, the two drugs work differently from each other.
Wayne Ray, a professor of preventive medicine at Vanderbilt University and lead author of the study, says he believes many doctors prescribe azithromycin instead of amoxicillin because of its easier regimen; patients on azithromycin take fewer pills over fewer days, which means they are more likely to finish their entire course of medicine. Finishing the entire course not only leads to more effective treatment, but it also lessens the risk of the patient developing a drug-resistant bug.
But, Ray says of azithromycin, “the risk of death may outweigh convenience and compliance, at least for high-risk patients.”
These high-risk patients would seem to be those who have certain types of cardiovascular disease. Some doctors have suggested that azithromycin may cause irregular heartbeats known as arrhythmias, which in some people can lead to death. In Ray’s study, which looked at Medicaid patients from 1992 to 2006 and analyzed millions of prescriptions, he and his colleagues found that patients on azithromycin had two and a half times the odds of dying from a cardiovascular cause while taking their medication than did patients on amoxicillin. The gap was widest when looking at the 10 percent of patients with the worst cardiovascular disease.
The study couldn’t tease out which patients were on azithromycin because they had allergies to amoxicillin.
Cardiologist Leonard Ilkhanoff, director of the Inherited Arrhythmia Program at Northwestern University’s Feinberg School of Medicine in Chicago, says that while it’s impossible to know what precisely is causing the increased risk of death, the study is very interesting. But he cautions that patients on azithromycin should not panic.
The FDA currently recommends that patients taking azithromycin continue to take the drug.
Jupiterimages/Thinkstock(MIAMI) -- A man who elected to have a penile implant in a Florida hospital is now suing his doctor after a post-surgical infection resulted in the amputation of his organ.
Enrique Milla, 65, who was reportedly deported from the United States last year back to his native Peru, has been testifying in court via Skype that the medical procedure robbed him of his dignity and manhood.
In a medical malpractice trial that began this week, Milla claims that his doctors should have known that he was not a good candidate for the procedure because of his diabetes and high blood pressure.
"This has been devastating, painful and embarrassing," said Milla's attorney, Spencer Aronfeld of Coral Gables, according to ABC's affiliate WPLG.
Milla alleges that his anesthesiologist Dr. Laurentiu Boeru "failed to evaluate properly the risks of this procedure." He first filed the lawsuit in 2009, naming Boeru and Dr. Paul Perito, the urologist who performed the surgery.
According to the Miami Herald, which obtained records that are not publicly available, Perito settled the case out of court.
Penile implant surgery is most commonly performed after all other treatments for erectile dysfunction have failed. It is also used to treat some cases of Peyronie's disease, a condition that causes scarring inside the penis, leading to bent, painful erections.
Implant surgery comes with a risk of infection, which can occur at any time after surgery -- in rare cases, even years later, according to the Mayo Clinic.
Milla suffered from a number of medical conditions, including erectile dysfunction, according to court records. Milla, who had lived in Miami for 40 years working in a medical supply business, received the surgery in 2007 at Coral Gables Hospital. But two weeks after the operation, Milla developed an infection that eventually turned to gangrene. Amputation of his penis was necessary to save his life, according to his lawyer, who alleges Boeru didn't exercise proper care after the surgery.
"Post-operative period is about anywhere between six to 24 hours after surgery. It does not include either days or months," testified Boeru.
"This is an infection that occurred in this gentleman because he didn't do what he was supposed to do post-operatively nine days after the surgery," Boeru's lawyer Jay Chimpoulis, told WPLG.
He suggested that Milla ignored medical instructions to avoid sex and developed a fecal infection.
"There are any number of ways he could've gotten that. None of them had anything to do with [Boeru]," Chimpoulis said.
Dr. Pravin Rao, director of reproductive medicine and surgery at the Johns Hopkins Brady Urological Institute, said penile implants, called prostheses, are safe for patients who are in good health -- even those with diabetes, as long as the disease is "controlled." The risk rate is lower than three percent, according to Rao, who did not treat Milla.
Penile implants are among a "long algorithm of options" for those with erectile dysfunction, according to Rao. Urologists start with pills like Viagra -- the least invasive approach -- to vacuum erection devices and injection therapy. But sometimes those treatments fail because of the quality of the tissue in the penis or poor blood flow. The most common reason for ED is chronic disease that affects the vessels in the penis -- most often diabetes, hypertension, smoking or high cholesterol. Nerve damage, caused by spinal cord injuries, diabetes or radical prostate cancer surgery, can also trigger ED.
A poor candidate for a prosthesis is someone who is not in overall good health and may be at risk under anesthesia or not be able to withstand the blood loss of surgery.
"The number-one concern is infection, and that's why we make sure their overall health and immune status are good and their diabetes is under control," said Rao.
When infection does occur, the prosthesis must be immediately removed to clear the infection.
The prosthesis is an inflatable device that is inserted in the two tubes of the penis. The balloons can be filled up with fluid, creating an erection. A small pump is placed in the scrotum with a reservoir of fluid that connects to the tubing.
"When we first place it, we don't have it activated to create a full erection," said Rao. "Then after letting it heal for six weeks, [the patient] comes in and we teach them how to use the pump by squeezing it."
Patients are told not to have sex during that recuperative period.
Rao said that penile implants are "very successful and infection is not the norm."
Some studies of patients with diabetes and those without the disease had the same rate of infection. "But," he said, "we have to be prudent about picking the patient."
iStockphoto/Thinkstock(LONDON) -- Four rounds of in-vitro fertilization couldn’t help Sara Conyers conceive, according to the U.K.’s Daily Mail.
But the fifth time was the charm for Conyers, 33, who now has twins. Conyers says the only way she could get pregnant was with the help of an experimental fertility method called intralipid infusion, Conyers, who lives in the U.K., told the Daily Mail.
The procedure, more commonly used in the U.K. than in the U.S., is used to supplement another fertility treatment, such as in-vitro fertilization. The woman is intravenously given a fat solution consisting partly of soybean oil and egg yolk.
Some experts who tout its success say it can prevent miscarriage by limiting activity of overactive so-called natural killer immune cells found in the body that would otherwise destroy the embryo.
But many fertility experts in the U.S. are not so sure about its effectiveness, since there are no definitive studies to suggest that the method works or is even safe.
“Before I can endorse this theoretical therapy for my patients, I need at least some evidence,” said Dr. Michael Murray, director of reproductive endocrinology and infertility at Northern California Fertility Medical Center.
This procedure is one of many that some of Murray’s patients ask him about, who are “grasping at straws for a solution to their recurrent miscarriages,” he says.
And some experts agreed, comparing the fertility-boosting procedure to others that are seemingly inexpensive with unknown risks for side effects, such as herbal supplements.
Previous studies done on animals or in lab dishes have found conflicting results about whether intralipid infusion works. Studies are also conflicted about the role that natural killer cells play in fertility.
“Most of the time when IVF fails, it is due to the quality of the embryos that were transferred and not the immune environment in the uterus,” said Dr. Tamer Yalcinkaya, section head of reproductive endocrinology and infertility at Wake Forest Baptist Medical Center.
If the scientific evidence supported the claims, intralipid infusion may benefit women with good quality embryos who have undergone previous IVF cycles but haven’t yet been able to conceive, said Yalcinkaya.
As for Conyers’ multiple unsuccessful IVF tries followed by one supplemented by intralipid infusion that worked, some experts say it’s hard to tell what part of that equation turned out to be the tipping point for Conyers.
“Success of a repeat IVF cycle may be a chance event and does not necessarily indicate that the need of an intervention was the cause of that improvement,” said Yalcinkaya.
iStockphoto/Thinkstock(LA JOLLA, Calif.) -- “Cut back on calories” seems to be the dietary mantra when it comes to reducing weight.
However, a study on mice published Thursday in the Journal of Cell Metabolism suggests that losing weight may have less to do with watching calories — and more to do with watching the clock.
“For millions of years, we humans spent our lives as diurnal species — eating most of our calories only in the daytime and fasting overnight,” said Satchin Panda, associate professor at the Salk Institute for Biological Studies in La Jolla, Calif., and lead author on the study. “In the last one hundred years or so, we have started to stay up at night and consume calories at night too. During this time, we have also observed an increase in the cases of diabetes and obesity.”
This study found that mice that consumed as many calories as they wanted for eight hours and fasted for the remaining 16 hours were essentially the same as mice that ate a healthy diet when it came to gaining weight, diabetes risk and high cholesterol.
“The gist of this study is that the timing and the number of hours you fast impact your weight gain,” Panda said. “Watch the times of day you eat as opposed to what exactly you eat. You don’t have to be as strict in counting calories.”
So what does this mean for humans wanting to lose weight and reduce their risk for diabetes and high cholesterol? Dr. Darwin Deen, professor at City College of New York, said he is cautious of these findings as well as translating a study on mice to humans.
“In all of human history, there are more calories now to get fat with,” he said. “Now, when we wake up in the morning, the question isn’t, ‘Is there food to eat?’ but ‘What would you like to have for breakfast?’
“Perhaps the best conclusion from this study is eating at night is not the best idea and having a more regulated diet is something we need to aim for.”
Keith Ayoob, associate professor in the department of pediatrics at Albert Einstein College of Medicine, has similar thoughts. “Mice are mice. Humans work differently,” said Ayoob. “A high-calorie diet in eight hours can be a slippery slope; almost like a loaded gun.” His advice?
Ayoob suggested eating a balanced diet — three meals a day with a snack. Breakfast eaters control their weight better than those who go for longer periods without eating and in turn, gain more weight. Additionally, he said, long-term weight management needs an activity component.
“Move! We focus a lot on food and diet, but activity is deal breaker.”
Dr. George Blackburn, associate director of the division of nutrition at Harvard Medical School, advises that developing a routine with a structured eating pattern is key. For example, it is important to eat breakfast because people are most active between breakfast and dinner, so calories are easily burned. The last meal should be eight to 10 hours after breakfast.
“This is a report that gives us one piece of knowledge that is valuable to us — have a time- restricted eating pattern that begins with breakfast,” Blackburn said.
Ultimately, Panda feels that this study shows that reducing the number of hours in which we eat and increasing the number of hours we fast can have significant effects on weight and risk for diabetes and high cholesterol.
“Over the last 50 years, we have come up with two lifestyle interventions for diabetes prevention — reduce caloric intake and increase exercise,” he said. “What we find today is that the calories in breakfast are different than the calories consumed in a midnight snack. Not all calories are created equal.”
Siri Stafford/Photodisc/Thinkstock(NEW YORK) -- Whenever the doctor says “you’ll only feel a pinch” when giving an injection, it may feel more like a punch. Now, you can do yourself a big favor, according to one German researcher, by not watching the needle -- because it tends to hurt less that way.
“Throughout our lives, we repeatedly experience that needles cause pain when pricking our skin, but situational expectations, like information given by the clinician prior to an injection, may also influence how viewing needle pricks affects pain," Marion Höfle explains.
Höfle’s team studied participants watching video clips of hands being pricked by a needle or just hands alone as the participants also received painful or non-painful electrical stimuli applied to their own hands.
The bottom line was they complained of more pain from the electrical stimuli when watching videos of the needle pricks than just seeing clips of hands. So they recommend looking away the next time you go in for a shot.
Cultura/Getty Images(NEW YORK) -- A new survey shows 63 percent of Americans take a vitamin or supplement, but many wish the manufacturers would come up with a vitamin that would improve their significant other’s listening skills.
A survey commissioned by The Vitamin Shoppe finds 50 percent of respondents wish there was a pill that could improve their partner’s listening. Forty-three percent wish there was a vitamin that would improve their significant other’s cleaning skills, while 31 percent expressed a desire for a vitamin that would improve their partner’s “bedroom” skills.
Respondents were asked: “If your significant other could take a vitamin to improve upon any of the following areas, which would you choose?
Listening, 50 percent
Cleaning, 43 percent
Physique, 37 percent
Cooking, 35 percent
“Bedroom” Skills, 31 percent
Dancing, 24 percent
Don’t know/Refused, 20 percent
Additional findings from The Vitamin Shoppe survey:
93 percent of Americans feel more confident about their health when taking a vitamin or supplement.
72 percent of respondents take multivitamins on a regular basis.
56 percent believe vitamins and supplements are necessary to achieve your health and fitness goals.
Respondents were also asked: “What would put you in a better mood – good sex or a good workout?
Good sex, 57 percent
Good workout, 35 percent
Don’t know/Refused, 8 percent
The Vitamin Shoppe survey of 1,000 U.S. adults was conducted by Wakefield Research.
Gerald Zanetti/FoodPix(NEW YORK) -- Hey, coffee lovers, here's another reason to defend that java habit you just can't kick. A study published Wednesday in the New England Journal of Medicine found that coffee drinkers are less likely to die from several common health conditions, including heart disease, stroke, diabetes, accidents and infections, than non-coffee drinkers are.
Researchers from the National Cancer Institute conducted an observational study from data that included 400,000 adults ages 50 to 71. People who drank three or more cups of coffee per day had a 10-percent lower risk of death from the aforementioned conditions than the non-coffee drinkers.
"Coffee is one of the most widely consumed beverages in America, but the association between coffee consumption and risk of death has been unclear," Neal Freedman, lead author of the study and an investigator in the National Cancer Institute's division of cancer epidemiology and genetics, said in a statement.
"We found coffee consumption to be associated with lower risk of death overall, and of death from a number of different causes,'' he said. "Although we cannot infer a causal relationship between coffee drinking and lower risk of death, we believe these results do provide some reassurance that coffee drinking does not adversely affect health."
And it may not be caffeine that is the protective ingredient. Those who drank caffeinated and decaffeinated coffee had similar health results, which suggests there is some other component in the coffee, not the caffeine, that plays a role in protecting one's health.
Several studies have found that coffee reduces the risk of several other medical conditions, including stroke, depression, dementia and several other cancers.
More than half of American adults drink some form of coffee each day, according to the National Coffee Association, and caffeine is the most frequently consumed stimulant in the world.
Despite the promising benefits, Dr. Cheryl Williams, a registered dietician with the Emory Heart & Vascular Center in Atlanta, said she would advise patients that coffee does indeed contain properties that may promote health, but it also has properties that can negatively affect health. Caffeine can raise blood pressure, she said, and boiled coffee lipids may increase already-high blood cholesterol.
"Overall, more research needs to be done to truly understand the compounds in coffee and their biological activity and effect on health," said Williams.
Drinking coffee is "fine," said Keith Ayoob, associate professor of pediatrics at the Albert Einstein College of Medicine in New York.
"It can be part of a healthy diet and lifestyle and may even contribute to such a lifestyle," said Ayoob. "I wouldn't want it to push out nutritious foods, but in and of itself, there is no reason to suggest that drinking coffee is negative, and it may be beneficial."
The study authors did note that coffee drinking was also associated with smoking, poor diets and alcohol consumption, but Ayoob noted that this doesn't necessarily mean coffee is bad for your health like some of the others.
"You're picking up on a long-term lifestyle, for better or worse," said Ayoob. "[But] just because coffee drinking accompanies smoking, inactivity, etc. doesn't mean it's bad, it means coffee is hanging around some bad company."
Hemera/Thinkstock(NEW YORK) -- She's only eight, but Lacey-Mae Mason is already a beauty pageant veteran. She competed in her first one when she was 14 months old.
But despite seven years of experience, the little girl from Brooklyn, Conn., faces perhaps her biggest pageant challenge yet in a nationwide competition chronicled on the upcoming season of TLC's show Toddlers & Tiaras.
What sets Lacey-Mae apart from the other little girls on the show is that she has achondroplasia, the most common type of dwarfism. Although she's about twice as old, she is about as big as a three-and-a-half-year-old, said her mother, Kerry Ann Mason.
But judging from the mantle full of awards and trophies she's already won, her condition hasn't stopped her from wowing judges.
"Her size hasn't been an issue," said her mother. "People notice there's something different about her, but I'm not sure it plays much of a role."
Toddlers & Tiaras has generated a lot of controversy, with critics accusing mothers of sexualizing their young children and pushing them to pint-sized perfection at any cost. But Mason said she got Lacey-Mae involved in pageants to teach her daughter that she is beautiful no matter what her physical limitations may be.
"She entered her first pageant because they were handing out trophies just for participating," Mason said. "I thought it would be great for her self-esteem to tell her one day that the trophy on her mantle was from a beauty pageant."
Child psychologists say the chance for children with disabilities to participate in the same activities as non-disabled children can be beneficial, as long as they are not exploited and actually want to participate.
"Any time you can give a kid a more normal experience, it's a good thing for kids and people in general," said Alan Hilfer, chief psychologist at Maimonides Medical Center in Brooklyn, N.Y.
While not endorsing the idea of child beauty pageants, Hilfer said including people whose appearance may not be considered normal can be a powerful teaching moment.
"This is a chance for this little girl to feel special with the spotlight of positive attention on her," said Fran Walfish, a child and family psychologist in Beverly Hills, Calif. and author of The Self-Aware Parent. "This could really be helpful to her self-esteem."
But psychologists also said it's important for Lacey-Mae to be the one who really wants to compete.
"If she is feeling pressured to do it and other kids give her a hard time and tease her, it's not going to be good for her mental health," said Nadine Kaslow, professor and vice chair of Emory University's Department of Psychiatry.
ABC News(NEW YORK) -- They are a mother and daughter who consider each other best friends. And yet, Bernadette and her 14-year-old daughter, Taylor, who asked that 20/20 not reveal their last names, don't eat meals together, don't share any activities and don't even speak to each other. It's all because everyday sounds Bernadette makes -- clearing her throat or sighing -- can send Taylor to the brink.
"It's like an almost undescribable amount of anger and, like, rage that I just can't control," Taylor told 20/20.
Taylor suffers from misophonia, a mysterious condition whose name literally means "hatred of sound." Misophonia makes it difficult to tolerate everyday noises such as chewing, coughing, even breathing. And while many might say they get annoyed at such sounds, for those with misophonia, the consequences of hearing such "trigger" noises are far worse than mere irritation: violence, isolation, depression and even thoughts of suicide.
Taylor has attempted suicide three times -- attempts, she said, were triggered by anti-depressants that did nothing to help her misophonia.
"I don't want her to give up, 'cause she's tried to give up," said Taylor's sister, Alex. "I just want her to keep moving."
Taylor's symptoms began when she was 8-years-old.
"I coughed, and she covered her ears, and she ran away," Bernadette said.
Eventually, it grew much worse.
"She's hit my head against the wall. She's kicked me. She's pushed me," Bernadette said, "just whatever she can [do] to stop the sound from coming from me. "
Once the rages pass, Bernadette said Taylor immediately feels remorse for her behavior. But the teen told 20/20 that when in the grips of such a rage triggered by an offending sound, that "sound will replay in my mind until I get the anger out ... until I somehow get out all my frustration."
Audiologist Marsha Johnson of the Oregon Tinnitus and Hyperacusis Treatment Center is one of the only experts who treats misophonia patients. Johnson said the cause of misophonia is suspected to be a "neurological glitch in a very low level of the brain." Watch the full story on 20/20 Friday at 10 p.m. ET.
Comstock/Thinkstock(HOUSTON) -- A vaccine may be able to keep an aggressive type of breast cancer from returning in women who have a history of the disease, according to early results of a new study. The vaccine still needs further research, but breast cancer experts say the results are promising.
Researchers at the MD Anderson Cancer Center in Houston developed a vaccine, called AE37, that trains the body's immune system to attack a common piece found on breast cancer tumors, a protein called HER2, which helps tumors grow.
"With this vaccine, we've educated the immune system to recognize this protein, HER2," said Dr. Elizabeth Mittendorf, the lead investigator on the trial. "If some rogue tumor cell is floating around, it can recognize it and take care of it before it can settle into bone or other parts of the body."
About 25 percent of breast cancer cases have an overactive amount of the HER2 protein, called HER2-positive breast cancer. This form of breast cancer is usually more aggressive and harder to treat than other types. But most tumors usually have some level of the protein, even if the amount is not enough to be classified as HER2-positive.
Mittendorf said one of the most encouraging things about the vaccine is that it seemed to reduce the risk of recurrent breast cancer in women who had both high and low levels of HER2, a group that accounts for about 70 percent of all breast cancer cases.
Mittendorf and her team studied 201 patients who had a history of breast cancer but who were disease-free at the time, giving the vaccine to about half of them. Based on the early outcomes of patients in the trial, the researchers projected that breast cancer would come back for 10.3 percent of the women who got the vaccine compared with 18 percent of the women who had not been vaccinated. That translates to a 43-percent reduced risk of recurrent breast cancer.
The study's results will be presented next month at a meeting of the American Society of Clinical Oncology.
Dr. Michele Zembo, 57, was one of the patients who got the vaccine. The pediatric orthopedic surgeon from New Orleans was diagnosed with breast cancer in October 2010 and after a year of chemotherapy, a mastectomy, radiation therapy and reconstructive surgery, she knew that her battle with breast cancer may not be over.
"That's just a reality of breast cancer. Somewhere down the line, there is that risk that it will come back," she said. "So you start wondering, what can I do to reduce my risk?"
She got regular exercise, changed her diet and even changed her high blood pressure medication when new evidence suggested beta blockers might reduce the risk of breast cancer. When her doctor told her about the clinical trial testing the AE37 vaccine, she did her research and decided to join the study.
Zembo said she experienced almost no side effects of the vaccine, just a minor rash and pain where the shots of the vaccine were injected. So far, Zembo said she is still free of breast cancer.
"I've tried to do everything that I can do to try to decrease my risk of recurrence. To me, this vaccine is one additional step, and a big step, that does that," Zembo said.
Breast cancer experts said the results of the study so far are promising, but they were cautiously optimistic. The number of patients in the study was relatively small, and they were monitored for less than a year. Women who have had breast cancer are at risk for recurrences for many years after their first diagnosis.
"We've seen a lot of treatments that have very early promise, but with follow-up studies just don't pan out, said Dr. Jay Brooks, chair of hematology and oncology at Ochsner Health System in New Orleans. "But it's interesting and something I would love to use in my practice if it proved successful."
The study is ongoing, and Mittendorf said it should finish in the fall of 2012. She hopes to launch a larger trial for the vaccine after that.
Mittendorf said the vaccine isn't useful for treating patients with advanced forms of the disease and isn't intended to replace other forms of treatment but to work in conjunction with them to fight breast cancer.
Comstock/Thinkstock(NEW YORK) -- Parents of teens know that at that certain age they can’t avoid having the dreaded “sex talk” with their kids, but what about with their pets? What if pet owners started thinking of their pets as their teens when it comes to avoiding pregnancy?
That’s the dramatic, but humorous, approach taken in a new series of public service announcements and advertisements produced by the Best Friends Animal Society, the nation’s largest sanctuary for homeless animals.
In the spots, voiced by NCIS: Los Angeles actress Linda Hunt and Modern Family star Eric Stonestreet, parents appear to be reacting to their kids’ promiscuity, only to have the kids replaced by their pets. In other words, once you start thinking of your pets as your kids, it’s a lot easier to think of what needs to be done to keep them from delivering offspring.
Called “Prevent more. Fix at month four,” the campaign is the first national effort to educate pet owners on when, not just why, they should spay and neuter, according to the Society.
“We felt it was important to present the messaging in an attention-getting way that didn’t make people feel guilty or sad,” Amber Ayers, the society’s senior marketing and creative manager, told ABC News. “When we looked at the research, most people planned on spaying or neutering their pets, but there was just a lot of confusion about when to do so and this leads to the ‘oops’ litter. ”
The Utah-based non-profit says it hopes the ads will grow into a “cultural movement.”
“We are hoping to maintain long-term traction by shifting the mindset of our country,” said Ayers. “It will become commonplace to fix your pet at four months, reducing the number of pets that enter, and ultimately never leave our shelters. ”
iStockphoto/Thinkstock(NASHVILLE, Tenn.) -- Patients prescribed the antibiotic azithromycin are more likely to die than those prescribed a different antibiotic, according to a study published in the New England Journal of Medicine on Wednesday. These results were especially pronounced for those who died from heart attacks, strokes, sudden cardiac death and other cardiovascular causes.
Azithromycin, commonly known by the trade name Z-Pak, is prescribed to almost 50 million Americans every year. Like the popular antibiotic amoxicillin, azithromycin is commonly prescribed to help fight off bacterial infections. But while they are often prescribed for similar conditions, the two drugs work differently from one another.
Wayne Ray, professor of preventive medicine at Vanderbilt University, in Nashville, Tenn., and lead author of the study, says he thinks many doctors prescribe azithromycin instead of amoxicillin because of its easier regimen; patients on azithromycin take fewer pills over fewer days, which means they are more likely to finish their entire course of medicine. Finishing the entire course not only leads to more effective treatment, but it also lessens the risk of the patient developing a drug-resistant bug.
But, Ray says of azithromycin, “the risk of death may outweigh convenience and compliance, at least for high-risk patients.”
These high-risk patients would seem to be those who have certain types of cardiovascular disease. Some doctors have suggested that azithromycin may cause irregular heartbeats known as arrhythmias, which in some people can lead to death. In Ray’s study, which looked at Medicaid patients from 1992 to 2006 and analyzed millions of prescriptions, he and his colleagues found that patients on azithromycin had two and a half times the odds of dying from a cardiovascular cause while taking their medication than did patients on amoxicillin.

Cardiologist Leonard Ilkhanoff, director of the Inherited Arrhythmia Program at Northwestern University’s Feinberg School of Medicine, in Chicago, says that while it’s impossible to know what precisely is causing the increased risk of death, the study is very interesting. But he cautions that patients on azithromycin should not panic.
“Patients shouldn’t be thinking, ‘If I’m on azithromycin, I’m going to die,’” he says, adding that sometimes azithromycin really is the proper antibiotic for a patient.
“It’s appropriate, though, to discuss the risks and benefits with your doctor.”
ABC News Radio(WASHINGTON) -- Americans are a step closer to being able to quickly determine in the privacy of their own homes whether they’re infected with HIV, the virus that causes AIDS.
An advisory panel to the U.S. Food and Drug Administration Tuesday voted 17-0 in favor of approving the OraQuick In-Home HIV Test, which produces results within 20 minutes of a quick swab along the gum line. A positive test result still must be confirmed with a traditional blood test performed in a laboratory.
The FDA, which isn’t bound by the recommendations of its advisory panels, is expected to make a final decision about the home test this year. A thumbs-up for the over-the-counter test kit from OraSure Technologies Inc., of Bethlehem, Pa., has the potential to reduce the number of people who unknowingly spread the virus because they’re unaware they’re infected. An estimated quarter million Americans are HIV-positive, but haven’t been tested. Each year, about 50,000 Americans become infected.
The FDA has estimated that 2.8 million people might test themselves in the first year after the over-the-counter test becomes available. FDA projected that the test could pick up 45,000 infections that otherwise would have remained undetected, while missing 3,800 infections, based upon the test’s 93 percent rate of correctly identifying infections in clinical trials. In addition, the agency estimated that by identifying 45,000 HIV-positive people, the test could prevent them from unwittingly transmitting it to another 4,000 people.
“This is a big step forward for HIV prevention. Anything that encourages people to get tested is a good thing,” said Dr. Richard Besser, ABC News chief health and medical editor, and a former acting director of the federal Centers for Disease Control and Prevention. “Twenty percent of Americans with HIV don’t even know it. It’s hard to prevent the spread if you don’t even know you’re infected. HIV is now a treatable as well as preventable disease.”
Besser said it’s important that anyone who gets tested, whether at home or in a doctor’s office, “is connected to support services.”
ABC News(PROVIDENCE, R.I.) -- A 58-year-old woman paralyzed by a stroke was all smiles after sipping her cinnamon latte with the help of a mind-controlled robotic arm.
Cathy Hutchinson is one of two tetraplegic patients able to reach and grasp with a robotic limb linked to a tiny sensor in her brain, according to a study published Wednesday in the journal Nature. The device, called BrainGate, bypasses the nerve circuits broken by the brainstem stroke and replaces them with wires that run outside Hutchinson's body. The implanted sensor is about the size of a baby aspirin.
"You can go from the brain, which seems to be working quite well, directly to a device like a computer or a robotic arm," said BrianGate developer John Donoghue, director of the Institute for Brain Science at Brown University in Providence, R.I. "This can help restore independence to a person who was completely reliant on other people for every activity, whether it's brushing their teeth, eating their dinner or taking a drink."
Hutchinson, who has been unable to move or speak for 15 years, had the 96-channel sensor implanted in her brain's motor cortex in 2005. Since then, the BrainGate team has been fine-tuning the system to give her back some of the control she lost.
For most people, reaching and grasping is effortless. But the simple movement is guided by a complex pattern of brain activity, according to Donoghue.
With its hair-like electrodes, the BrainGate sensor taps into the flurry of brain activity, recording electrical signals that can be translated into movement commands. BrainGate also allows Hutchinson to move a computer cursor so she can communicate. But the device is not quite ready for prime time, Donoghue cautioned.
"Currently patients have a plug on their heads and need to be connected by to a cart full of electronics," he said. "We need to replace it with a wireless system."
Donoghue is collaborating with Arto Nurmikko, a neuroengineer at Brown, to do just that.
While the BrainGate system can currently control an external device, like a robotic arm, it could one day control a person's muscles.
