    Singer Adele's hit song, "Rolling in the Deep," is credited with helping a 7-year-old British girl wake from the coma she suffered after a brain hemorrhage.

    Charlotte Neve suffered the hemorrhage April 11 during a normal night of watching DVDs with her family, and mother Leila told the U.K. Telegraph that the situation became so grave that "doctors told me to say goodbye."

    But when "Rolling in the Deep," a song mother and daughter often sang, came on the radio, Leila Neve started singing it to her daughter and the little girl started to smile.

    "It was the first time she had reacted to anything since the hemorrhage," Leila Neve told the newspaper. "The nurses were astounded and told me to keep singing, and she smiled again. The nurses said it was like I 'unlocked her' and from that day she started getting better and better."


    Charlotte Neve is now recovering at home, but still suffers from partial blindness and memory loss, the Telegraph reports. The family has set up a Facebook page for donations.

    Also in April, BeeGees founding member Robin Gibb awoke from a coma after his family sang and played music to him. He reportedly awoke while music from his latest composition, the classical "Titanic Requiem," was playing. Gibb died May 20 from liver and kidney failure.

  • The doctor is in: your questions on food allergies, pertussis, migraines and more

     

    Dr. Tyeese Gaines, an emergency medicine physician and health editor for theGrio.com, answers your questions about everything from shingles to concussions. Got a question you'd like her to answer in an upcoming column? Send it to askdoctorty@gmail.com.

    Q: Is it normal for a child to develop a food allergy all of a sudden (in this case, shellfish)?
    - Elizabeth C.
    A: Yes. Allergies can develop at any time. They’re more likely to start in childhood, but anyone -- even adults -- can become allergic to foods that that person has eaten his or her entire life.

    Q: I’m pregnant with our second child and due in August. Both my obstetrician and my son’s pediatrician recommend that my husband and I get a pertussis booster shot (for whooping cough).  My husband was in the ER and given a tetanus shot. Do all tetanus shots come with pertussis in them?
    - Sarah D. J.
    A: No. There are vaccines with tetanus alone, and others with both tetanus and pertussis. We get excited about pertussis vaccination because pertussis -- the bacteria that causes whooping cough -- is highly contagious and dangerous to infants. The current recommendation is to give pertussis when adults get tetanus vaccines because it decreases the chances of adults passing pertussis onto the children.

    Q: Why is it that when I go to the emergency room for a mega migraine everyone assumes I am a pill popper or drug addict? If I wasn’t in such unbearable pain and vomiting, I wouldn’t go.
    - Aron B.
    A: Unfortunately, there are people looking for prescription pain medication for the wrong reasons -- not because they have pain, but because they either want to get a euphoric high or sell the pills illegally. The problem is, it can be difficult to tell the difference. If you have two patients writhing in pain, but one is being deceptive, how do you know? And, in your case, patients who come in frequently do tend to raise flags. The best thing to do is get a good primary physician who knows you well. Either he or she can prescribe you pain medication and help you avoid the emergency room altogether or that physician can call the ER and “vouch” for you and the fact that you’re not drug-seeking. 

    Q: Black spots keep coming up on my face, and my neck is darker than the rest of my body, what can I do to clear it up?
    - Nic-nak J.
    A: The neck can be darker than the rest of the body, especially in the folds, in a condition called acanthosis nigricans. Sometimes, it is benign, other times it means there is an underlying health problem. Acanthosis nigricans affects people of African descent more often, and tends to run in families. Obesity and other hormonal problems can lead to this discoloration. And, it is often seen in obesity-related diabetes -- sometimes as a warning sign long before the patient develops diabetes.  The darker discoloration can spread to the armpits, groin and finger joints. It fades once the underlying cause is treated.

    The spots that appear on the skin with age are usually signs of long-term sun damage. It also appears to be related to genetics. Visit your physician or a dermatologist to figure out whether those are aging spots or discoloration to be concerned about.

    Q: I am not a drinker. I may have a drink once or twice a month. Sometimes, when I drink, I get the “blood pressure headache.” Is it safe to pop another pill prior to having a drink in order to control my blood pressure?
    - Lynn E. P.
    A: This concept of people developing a headache when their blood pressure is high is often debated. The problem is, pain can increase a person’s blood pressure, so simply having a headache can make one’s blood pressure go up. If the blood pressure is taken at that point, who knows which caused which?

    With respect to your headache, some people do develop headaches when drinking alcohol. Some are very sensitive to the dehydration that comes with even a small amount of alcohol intake. Others are affected by the chemicals in certain types of alcohol, such as red wine -- a well-known trigger in migraine sufferers.

    Talk to your doctor and don’t assume that taking an extra blood pressure pill will prevent the headache. It may not be caused by your blood pressure at all.

    Q: If it’s late at night, or on a weekend, can you help parents decide if they should take their child to the ER as opposed to calling their on-call pediatrician or waiting until office hours?
    - Michelle V. S.
    A: If the child is having difficulty breathing, or some other life-threatening condition, call 911 immediately. Otherwise, call the pediatrician. There is always someone on call for their patients. The truth is, many pediatric ER visits can wait until the morning when the pediatrician’s office is open. Allow the doctor to help with that decision. He or she may even call in the prescriptions you need to the pharmacy without you having to come in.

  • Boomers' hep C tests may torpedo insurance chances, experts say

    Luis Robayo / AFP - Getty Images file

    A plan to urge hepatitis C testing for all baby boomers could promote treatment and save lives, but a positive result could also cause problems getting various kinds of insurance.

    A government proposal that all baby boomers get tested for hepatitis C may be drawing high praise for its potential health benefits, but it’s also raising questions about the unintended consequences of screening for those seeking insurance.

    Experts in health insurance, life insurance and long-term care insurance warn that boomers who test positive for the blood-borne virus before being approved may dash their chances for coverage.

    “I would never, ever tell anybody to delay getting any kind of medical exam,” said Jesse Slome, executive director of the American Association for Long-Term Care Insurance. “But you have an advantage over the insurance company if you apply for insurance before undergoing any kind of medical checkups.”

    For the first time, government health officials suggested in May that anyone born between 1945 and 1965 be tested for the hepatitis C virus, which can destroy the liver.

    The draft proposal, which could see a final ruling later this year, is aimed at getting some 800,000 baby boomers into treatment and potentially saving more than 120,000 lives, according to the Centers for Disease Control and Prevention.

    Baby boomers make up about 2 million of the estimated 3.2 million people infected with hepatitis C, the CDC says. About three-quarters of those who have the virus don’t know it -- and many don’t think they’re at risk for it, said Dr. John Ward, director for the Division for Viral Hepatitis.

    “Testing is the only way to identify these individuals in order to connect them to life-saving care and treatment,” he said.

    Hepatitis C is spread through contact with contaminated blood or organs. It was widely transmitted through routine health care practices before the virus was identified in 1989 and before widespread screening of the U.S. blood supply began in 1992.

    Social practices such as injection drug use and tattooing contributed to the problem, but so did unexpected transmission from routine exposures such as sharing toothbrushes or razors, even manicures and pedicures.

    Getting tested may confirm the unsuspected exposure and prompt treatment, a plan that’s drawing praise from many of the dozens who publicly commented on the CDC’s draft proposal.

    “This birth cohort screening, in my opinion, is the right methodology at the right time,” wrote Dr. Donald Jensen, a clinical and research expert in hepatitis at the University of Chicago. “The baby boomers are aging and need to be identified quickly before their disease and co-morbidities overtake them.”

    But a positive test for hepatitis C also can raise worries for those who aren’t insured or who want more or different insurance.

    “I am concerned that this will allow insurance companies to deny treatment for pre-existing conditions,” wrote Donna Bailey, a consumer commenter on the site.

    Even treatment for hepatitis C might not guarantee acceptance since current protocols may not be 100 percent effective.

    It’s true that hepatitis C is one of several chronic, life-threatening diseases that can exclude people from being insured, said Susan M. Pisano, vice president of communications for America’s Health Insurance Plans, the national trade association representing the industry.

    “You would have a condition if you were diagnosed, the same way you’d have a condition if you had asthma, diabetes or another condition,” she said.

    The difference is, a leading government health agency is suddenly recommending that an entire generation be screened for the condition in question. 

    CDC officials say they’ve considered the problem. About two out of three people diagnosed with hepatitis C have health insurance -- but about a third of those diagnosed do not, officials said.

    “Considerations regarding insurance coverage are real, affecting individuals and their loved ones ... ” Ward said in a statement to msnbc.com. “ ... These issues are ones we must continue to consider as part of any implementation of these recommendations.”

    Under the Obama Administration’s health reform law, insurers would not be able to reject adults with hepatitis C or another pre-existing condition starting in 2014. But the Supreme Court is expected to rule within the week on overturning all or part of the Affordable Care Act, so that mandate is unclear.

    Anticipating that the hepatitis C proposal may become final, CDC officials are working with insurance providers, public health agencies, commercial labs and others to coordinate the mechanics of such large-scale testing.

    Until something changes, at least one insurance broker advises his clients to think about the consequences of the test results.

    “It’s up to you,” said Michael McDonnell, a financial adviser who works at Individual Commercial Brokerage in northern California. “Test or not, insure or not. If you’re going to insure, wait until you are approved before doing the test.”

  • Weight-loss surgery linked to higher risk of abusing alcohol

    In a last ditch effort to lose weight, roughly 113,000 people subject themselves to bariatric surgeries such as stomach banding and gastric bypass every year in the United States. But some of those patients may be trading pounds for an alcohol problem, according to a new study presented today at the annual meeting of the American Society for Metabolic and Bariatric Surgery in San Diego, and published by the Journal of the American Medical Association.

    Hints that bariatric operations could lead to subsequent alcohol abuse have been collecting over the past few years, as case reports and doctor anecdotes have filtered into discussions and scientific publications. But the new study, headed by Wendy C. King, assistant professor of epidemiology at University of Pittsburgh’s graduate school of public health, is the first to follow many patients treated at a number of institutions from pre-op through two years post-surgery.

    In all, 1,945 adults were assessed from 2006 to 2011. Alcohol use disorder (AUD), meaning abuse and dependence, “significantly increased in the second post-operative year compared with the year prior to surgery or the first post-operative year,” the study says.

    The percentage seems small: At pre-operative assessment, 7.6 percent of study participants showed AUD. Two years after the operations, 9.6 percent did. Symptoms (without AUD) of alcohol dependence rose from 2.8 percent to 5.5 percent.

    But that translates into about 2,000 more people with an alcohol use disorder, as King pointed out in the study, and in an interview. And even if a patient does not have AUD, she said, “one in eight patients in the second post-operative year reported typically drinking at least three drinks” when they drank. “That level can have implications for their weight loss, liver function, vitamin and mineral status so that is concerning….We don’t know the safe amount of booze after a [gastric] bypass.”

    Almost the entire increase in AUD among bariatric surgery patients occurred in those receiving a type called Roux-en-Y gastric bypass. The biological mechanism at work has not yet been firmly established, but it likely rests in the differences between surgeries. In the Roux-en-Y procedure, doctors create a stomach pouch out of a small portion of the stomach and attach it directly to the small intestine.

    Banding surgeries are restrictive -- they shrink the available space in the stomach so a person feels full after a small amount of food. Gastric bypass surgeries are both restrictive and malabsorptive, meaning they shrink space for food and change how its nutrients are absorbed in the small intestine.

    As a result, gastric bypass patients feel alcohol’s effects faster, and for longer.

    So the study’s findings, while important, aren’t surprising, explained Leslie Heinberg, the director of behavioral services for the Bariatric and Metabolic Institute of the Cleveland Clinic. Previous research has shown that male brains receive a more powerful reward from alcohol and among the study participants, the greatest risk for post-op alcohol abuse was in men.

    Heinberg also pointed out one more prosaic possibility for an increase in AUD after surgery, one King acknowledged, too: When formerly obese people lose a lot of weight, they gain confidence, feel attractive, and may have more opportunity to socialize and drink.

    That could explain why drinking and AUD was actually lower during the first year after surgery while patients were losing weight, then spiked during the second year. “It may be an unintended consequence of doing a heck of a lot better,” Heinberg, who was not associated with the study, suggested.

    The findings should not dissuade anybody from a gastric bypass, Heinberg said, though both patients and doctors should weigh this information when considering risks and benefits of various surgeries.

    Anita Courcoulas, professor of surgery and chief of minimally invasive bariatric and general surgery at the University of Pittsburgh Medical Center, who was a co-author of the study, stressed that “surgeons need to counsel patients” about the possibility of AUD. Importantly, she said in an email to msnbc.com, bariatric surgery patients should be monitored closely for long periods of time “for signs and symptoms of alcohol use disorders and should consider counseling after bariatric surgery.”

  • Big jump seen in Oregon parents delaying vaccines

    An increasing number of parents may be choosing to delay or limit certain vaccinations for their young children, a new study shows, even as cases of pertussis, or whooping cough, continue to rise nationwide, with recent outbreaks in California and Washington.

    The study, which examined medical records for 97,711 Portland children, found an almost four-fold increase between 2006 and 2009 in the percentage of parents who delayed or skipped vaccinations, researchers reported in the journal Pediatrics. Experts say that by delaying certain vaccinations, parents may be putting their children -- and those of others -- at a far greater risk of contracting deadly diseases, such as pneumonia and pertussis.

    The new study examined the vaccination histories of children born in the Portland area between 2003 and 2009. Between 2006 and 2009, the number of parents who rejected government recommendations and made up their own vaccine schedules rose from 2.5 percent to 9.5 percent.

    While the researchers could not say how typical the Portland results are compared to other areas around the country -- Portland schools reportedly have some of the highest vaccine exemption rates in the U.S. --  a 2011 study published in Pediatrics found that 13 percent of parents nationwide were using alternative schedules. Another study published in Public Health Report in 2010 found that almost 22 percent of parents were deviating in some way from the CDC's recommendations for infant vaccinations -- either by delaying shots, leaving out certain vaccines, or skipping vaccinations altogether.

    The vaccine delays may not completely explain recent whooping cough outbreaks in states such as California and Washington, but “they certainly don’t help,” said Dr. Jaime Deville, a UCLA professor of infectious diseases in the pediatrics department.

    The main reason parents give for delaying shots is fear their children will be harmed by receiving multiple vaccines at the same time, according to the study’s lead author, Steve Robison, an epidemiologist at the Oregon Health Authority. The vaccines most likely to be delayed by 9 months were for hepatitis B and pneumococcal disease (pneumonia).

    For example, at both the two- and six-month visits the CDC recommends kids get a total of six vaccines. Even with some of them combined that adds up to a lot of shots. By age 4, children receive up to 28 vaccinations, based on the CDC immunization schedule.

    Some parents believe they’ll get the same benefit if they spread the vaccinations out over more doctors’ visits rather than getting them all at once.

    “There are rumors out there that your body can’t handle that many vaccines, that your body won’t be able to respond appropriately if you get several all at one time,” Robison said.

    Experts say vaccines pose no harm to babies; even though multiple shots can be painful for a few moments, they say the consequences of delaying vaccinations can be much worse.

    There are reasons for concern over the delayed vaccines. According to the Centers for Disease Control and Prevention there were 2,325 cases of pertussis in Washington state through June 9, 2012, compared to 171 during the same time period in 2011. A 2010 outbreak in California led to 9,143 cases -- including 10 infant deaths --  the most cases in that state since 1947.

    "We’d like parents to know that the recommended number of doses of a vaccine is what is needed to build adequate protection levels both for their child and for the community," Robison said. "One dose of a vaccine, such as for pertussis, doesn’t build enough protection."

    By 9 months, infants on an alternative vaccine schedule had fewer injections than those with parents following the government recommended schedule -- an average of 6.4 versus 10.4 shots -- and more doctors’ visits for vaccinations.

    What’s more, few had caught up with the recommended number of vaccinations by the end of the study.

    One big problem with the modified schedule is that parents are bringing children who haven’t been appropriately vaccinated into the doctor’s office more often  -- thus putting other kids at greater risk, said pediatrician Dr. Andrew Nowalk, an assistant professor at the Children’s Hospital of Pittsburgh at the University of Pittsburgh Medical Center.

    Deville is especially concerned about parents who are choosing to delay the pneumococcal vaccine until age 2. Infants are most vulnerable to pneumonia during the first year of life. "Parents who delay the vaccine until age 2 are leaving their children vulnerable during the period where it occurs at its highest frequency,” Deville said.

    An added advantage of the pneumococcal vaccine is that it lowers the amount of bacteria living in kids’ noses and throats, Nowalk said. “So the children who aren’t getting vaccinated are more likely to be carrying the bacteria without being infected and spreading it to others,” he added. “When you don’t vaccinate your child you’re not only putting your child at risk but also those of others.”

    Further, Nowalk said, there are lots of kids out there with immune deficiencies -- those with leukemia, or depressed immune systems because of organ transplants, for example -- who can't get vaccines. So they have to rely on everyone else getting vaccinated.

    “When enough of the population is immunized, transmission is essentially stopped,” Deville explained. “The bottom line is that immunizations are extremely safe. They have the most value of any of our interventions when it comes to prolonging life and preventing diseases – not only for our own children but also for the community.”

    Health officials in Washington state say whooping cough has reached epidemic levels. Hundreds of cases have been reported so far this year, six times more compared to the same period in 2011. NBC's Mike Taibbi reports.

  • Report: World's population is 17 million tons overweight

    Obesity is threatening the world’s future food security, according to a study published Monday that calculated the weight of the global population at 316 million tons.

    Researchers from the London School of Hygiene and Tropical Medicine said increasing levels of fatness around the world could have the same impact on global resources as an extra half a billion people.

    In a report published in the journal BMC Public Health [PDF file here], the researchers estimated that 17 million tons of the global body mass was due to people being overweight.


    Despite only making up five per cent of the world's population, the United States accounts for almost a third of the world's weight due to obesity, the researchers found.

    In contrast, Asia has 61 per cent of the world's population but only 13 per cent of the world's weight due to obesity.

    When working out is too much of a good thing 

    The study is published to coincide with the largest-ever United Nations conference, Rio+20, which will discuss sustainable development.

    Using World Health Organization data from 2005, the scientists calculated the average global body weight at 137 pounds, but in North America the average was 178 pounds.

    Get off your butt and exercise, orders your doc 

    One of the authors of the paper, Professor Ian Roberts, told the BBC: "When people think about environmental sustainability, they immediately focus on population. Actually, when it comes down to it, it’s not how many mouths there are to feed, it is how much flesh there is on the planet."

    "If every country in the world had the same level of fatness that we see in the USA, in weight terms that would be like an extra billion people of world average body mass," he added.

    Roberts said health campaigns and urban design that promotes walking or cycling were among the best ways to tackle the problem, which was primarily caused by sedentary modern lifestyles.

    “We do not move our bodies so much but we are biologically programmed to eat,” he told the Daily Telegraph. "We often point the finger at poor women in Africa having too many babies. But we've also got to think of this fatness thing; it's part of the same issue of exceeding our planetary limits."

  • Can taking vitamin D and calcium help you live longer?

    By Susan E. Matthews
    MyHealthNewsDaily

    Older people who take vitamin D supplements along with calcium may live longer than others, according to a new review of previous studies.

    The researchers looked at data regarding the vitamin D intake  of more than 70,000 adults in their 60s and 70s. They found that people who took vitamin D, along with calcium supplements, were 9 percent less likely to die over a three-year period, compared with people who took neither supplement.

    However, they found that taking vitamin D alone had no effect on mortality rates.

    For every 151 people who took with daily vitamin D and calcium for three years, one life would be spared, according to the researchers' calculations.

    The finding comes on the heels of several studies with conflicting results about the health benefits of vitamin D, including its possible effects on longevity. The new review is the largest of its kind, and included eight randomized controlled trials, said study leader Lars Rejnmark, of Aarhus University Hospital in Denmark. Such trials are considered the strongest type of scientific evidence.

    The study confirms researchers' suspicions  that vitamin D may increase longevity, said Dr. Philippe Autier of the International Prevention Research Institute, who was not involved in the review.

    Study participants were generally older people with health conditions, and possibly had inadequate nutrition. Therefore, it’s “not guaranteed that anyone in good health  who takes these vitamins would increase life expectancy,” Autier said.

    In the review, the researchers found that 5.5 percent of the 35,412 people who didn't take vitamin D or calcium died during the study period, whereas 5.3 percent of the 35,116 people who took vitamin D died. 

    Taking vitamin D, with or without calcium, had a significant effect on mortality rates only after three years; mortality rates were not significantly different among those taking the vitamin after one or two years, according to the study.

    Vitamin D and calcium are important throughout life, because of their role in bone health, Rejnmark said. But he recommends people start paying particular attention to their intake "around menopause for women, and around the age of 50 for men."

    While the review was based on studies of people who took supplements, Rejnmark said he does not believe the benefits would be any different for people who get the nutrients through food.

    Autier noted that the greatest source of vitamin D is what the skin makes naturally when it is exposed to sunlight. People with darker skin tones, who are less able to produce vitamin D  in response to sunlight, should consider supplements as a viable option, he said.

    A total of 87 percent of the studies' participants were female, but Rejnmark said this had no bearing on the results, and vitamin D and calcium are equally beneficial to both sexes in terms of preserving longevity.

  • Thoughts of death make only the religious more devout

    By Stephanie Pappas
    LiveScience

    Thinking about death makes Christians and Muslims, but not atheists, more likely to believe in God, new research finds, suggesting that the old saying about "no atheists in foxholes" doesn't hold water.

    Agnostics, however, do become more willing to believe in God when reminded of death. The only catch is that they're equally as likely to believe in Buddha or Allah as the Christian deity, even though all the agnostics in the study were  American and thus more likely to be exposed to Christian beliefs.

    The findings confirm that while religion can help people deal with death, we all manage our own existential fears of dying through our pre-existing worldview, the researchers report in an upcoming issue of the journal Personality and Social Psychology Bulletin.

    "These studies offer an improved understanding of how and why religious individuals tend to believe so strongly in their own religion’s gods yet deny the gods of competing religions," the researchers wrote.

    Plenty of research has shown that religion, which frequently promises an everlasting afterlife, helps people cope with the fact that they will die someday. But this use of religion is not universal. One 2006 study found that thoughts of death increased belief in supernatural figures in general for religious people. That study did not separate atheists from agnostics, nor did it examine how specific religious beliefs might influence the sort of supernatural figures a person might believe in. [ Top 10 Unexplained Phenomena ]

    To find out, University of Missouri psychologist Kenneth Vail III and colleagues recruited 26 Christians, 28 atheists, 40 Muslims and 28 agnostics.. The participants were American college students, except for the Muslims, who were Iranians going to school in Iran. Each participant was tasked with writing either a brief essay about how they felt about their own death or a religiously neutral topic, such as loneliness or how to cope when plans go awry.

    After a brief verbal task to distract the participants from the true purpose of the study, they filled out questionnaires about their religious beliefs, including their faith in the Christian God or Jesus, Buddha and Allah.

    Unsurprisingly, when Christians thought of death, they became firmer in their beliefs than those Christians who hadn't been reminded of their mortality. They also became less accepting of Allah and Buddha, suggesting a closer adherence to their own worldview. Likewise, Muslims who thought of death became more faithful to Allah and less accepting of Buddha or the Christian God.

    Atheists, who reject religion, showed none of these responses to thoughts of death. In other words, the myth that atheists turn to God on the battlefield or in other times of peril didn't hold up, Vail and his colleagues wrote. Along with other research, their study suggests that "atheists do not rely on religion when confronted with the awareness of death," they said.

    Agnostics believe that the truth about God is unknowable. As far back as the 17th century, Catholic philosopher Blaise Pascal argued that if you don't know whether to believe in God, you should go ahead and do so — just to be safe. Pascal's Wager, as it's known, seemed to play out for the agnostics Vail and his colleagues studied. When they thought about their own mortality, these agnostics became more likely to believe in any deity, whether the Christian version, Allah or Buddha. In other words, they put their money on all three.

    The findings show how differently people manage their thoughts of death, Vail and his colleagues wrote. Future research might focus on spiritual types who believe in many paths to God, they said, or perhaps on non-theistic belief systems such as Confucianism or Taoism.

  • Germiest hot spots in hotels? TV remote, light switch, study finds

    Crusader / featurepics.com

    Do you really want to touch the remote? A small study of hotel rooms in three states found that the main light switch and the TV remote were two surfaces most contaminated with bacteria.

    Next time you enter a new hotel room, you might think twice before touching the light switch or reaching for the remote.

    Those are two of the top surfaces most likely to be contaminated with potentially sickening bacteria, according to a small new study aimed at boosting cleaning practices at the nation’s hotels and motels.

    Katie Kirsch, a University of Houston researcher, led a team that measured germs on everything from curtain rods to bathroom sinks in nine hotel rooms in three states.

    Kirsch came away thinking that the current industry standard of visual assessment -- if it looks clean, it is clean -- isn’t good enough.

    “A visual assessment can’t tell you about bacteria and viruses,” she told msnbc.com. “It can tell you what’s on the surface, but not if it’s been disinfected.”

    Kirsch, a recent graduate who has also studied subjects like the pathogens that linger on restaurant menus and the cleanliness of public bathrooms, enlisted colleagues at Purdue University and the University of South Carolina. They’re presenting their work Sunday at the annual meeting of the American Society for Microbiology.

    The researchers went looking for aerobic bacteria, which include germs known to cause illness, including streptococcus and staphylococcus. They also tested for coliform -- or fecal -- bugs. They swabbed the surfaces, put the samples on ice and then flew them to the University of Houston microbiology lab for analysis.

    Top hot spots for aerobic bacteria in hotels turned out to be the bathroom sinks and floors, the main light switches and the TV remotes. The remotes, for instance, racked up a mean of 67.6 colony-forming units of bacteria, or CFU, per cubic centimeter squared.

    For comparison, one study of environmental cleanliness in hospitals recommended a top limit of 5 CFU per cubic centimeter squared. Even using Kirsch’s relaxed proposal of 10 CFU, the TV remotes racked up way too many bugs.

    The main light switches in the rooms were worse, with a mean of 112.7 CFU for aerobic bacteria. Even the telephone keypad was icky, with 20.2 CFU.

    When it came to fecal bacteria, the main light switch was the most serious surface offender, with 111.1 CFU.

    That may sound disgusting, but it doesn’t necessarily mean hotel surfaces will make you sick, emphasized Kirsch, who said that her study wasn’t designed to test for the specific pathogens that cause illness.  Her supervisor underscored that it shouldn’t keep people from staying in hotels.

    “It’s not a scare thing,” said Jay Neal, an assistant professor in the Conrad N. Hilton College of Hotel and Restaurant management.

    Instead, Kirsch was conducting baseline research that she hopes might one day inspire the hotel industry to adopt cleaning and sanitation guidelines invoked through HACCP -- Hazard Analysis and Critical Control Points -- a protocol already used by food and healthcare industries.

    “The study is aimed more toward the housekeeping managers,” she noted.

    In addition to checking for the bugs on surfaces in the hotel rooms, the researchers also swabbed for bacteria on the gloves, mops and sponges used by cleaning staff, which have the potential to carry germs from room to room.

    Those items were crawling with all kinds of bacteria: at least 500 CFU of aerobic and fecal bacteria on the sponges, for instance.

    “When you’re in a hotel room, there’s that stranger factor,” said Neal, noting that no one wants to inherit fecal bacteria from the guy down the hall.

    Some hotels appear to be getting the message. Best Western hotels, for instance, just launched a campaign to equip its housekeepers with black light testers to detect unseen bugs. They’re even offering a sanitary wrap for the remotes.

    Hampton Inns have launched a campaign emphasizing cleanliness with commercials featuring a hotel guest dressed in a Hazmat suit.

    Meanwhile, ordinary guests fearful of hotel germs can take matters into their own hands, said Kirsch, who agreed traveling with sanitizing wipes is an option:

    “It would make consumers feel better to wipe down the surfaces.”

  • Does it matter if Sandusky has a personality disorder?

    Could Jerry Sandusky have a psychiatric condition that helps explain the alleged acts of sexual abuse he's currently on trial for? That's what the defense for the former Penn State assistant football coach intends to argue, according to court documents released today.

    Prosecutors have argued that letters Sandusky wrote to multiple young boys are proof of "grooming behavior" -- something pedophiles do that might include giving kids presents or acting nicely toward the child to establish an intimate relationship. Over time, it can make the child feel like he or she "owes" the predator sexual acts. The defense intends to argue that these letters exhibit signs of a histrionic personality disorder, a psychiatric condition in which people act in overly emotional and dramatic ways in order to draw attention to themselves.

    The defense may or may not succeed in arguing that an undiagnosed personality disorder explains the letters, but when it comes to the case as a whole, the psychiatric issue is irrelevant, says Dr. Liza Gold, clinical prof of psychology at Georgetown University.

    "This really has nothing to do with whether he molested boys," says Gold, who stresses that she has not examined Sandusky herself. 

    "There's no evidence that I know of that links personality disorder to pedophilia," she says. Some pedophiles may have a personality disorder, and some with a personality disorder may be pedophiles. But there's no correlation between the two, argues Gold, who also serves as the vice president of the American Academy of Psychiatry and the Law. "It's apples and oranges. It's not even apples and oranges; it's apples and rocks."

    People with histrionic personality disorder often need to feel like they're the center of attention, and they tend to seek endless reassurances and approval from others. They may believe a relationship is more intimate than it actually is, and they may act in inappropriately seductive ways toward other people. One hint of the disorder may be a string of failed romantic relationships or a history of many job changes -- and while that's not the case in all with the condition, it's worth noting that Sandusky has been married to the same woman since the late '60s, and he spent almost his entire three-decade career as an assistant coach at Penn State. 

    To diagnose a person with the disorder, a psychologist will consider his or her current and past patterns of behavior and overall psychiatric history, and compare them with the current definition of histrionic personality disorder according to the Diagnostic and Statistical Manual of Mental Disorders, usually referred to as the DSM.

    It's true that the defense could have evidence of a previous psychiatric history that hasn't been made public. But as Gold says, it's not uncommon for a person in legal trouble to claim they have a psychiatric disorder of some kind. She adds that it would be unusual for an older man to be diagnosed with the personality disorder late in life, especially because the condition is more common in women.

    "Even if he has a personality disorder, it would not, to my mind, explain any kind of behavior involving child abuse and inappropriate relationships with children," Gold reiterates. 

    "I think the money question is, So he has a histrionic personality disorder. So what?" she continues. "You have to show that there's some relationship to the behavior at issue. And the behavior at issue isn't writing some letters to some kids; the behavior at issue here is pedophilia."

  • Hidden hairs can strangle baby's tiny toes, doc warns

    Stephen Marks / Getty Images stock

    Sweet baby toes can be the source of a rare but painful condition called toe tourniquet syndrome, in which hair wraps around the tiny digit, cutting off circulation.

    When it comes to babies, it seems that danger lurks in the most unusual of places.  Certainly one would never see a wisp of human hair as a menace.

    But, as it turns out, if a single strand of hair wraps around a baby’s toe, it can cut off circulation and ultimately doom the appendage. Though rare, this happens often enough for doctors to have given it a name: toe tourniquet syndrome.

    Michelle Whelan’s baby was one of the lucky ones. One day as Whelan was changing her infant she noticed that several of her baby’s toes were beginning to turn purple. Whelan was sure if she couldn’t find out what was wrong that her baby might lose one or more of her toes.

    Fortunately for Whelan, the surgeon at her local hospital on Massachusetts' Nantucket Island, Dr. Timothy Lepore, recognized right away what had happened. He pulled out his magnifying glasses, spotted the culprit strand and cut it away.

    Whelan’s story, along with many other intriguing cases handled by Lepore, are described in the new book “Island Practice,” written by Pam Belluck, a New York Times health writer.

    “I didn’t know anything about toe tourniquet syndrome when I had my two kids,” says Belluck. “It’s not in any pregnancy books or first-year books. You’d think the hair would break, but it’s apparently very strong and can get 100 revolutions around a tiny toe if you have long hair.”

    The actual incidence of toe tourniquet syndrome is unknown, but doctors have documented dozens of reports of rare cases. The problem doesn’t always involve the toes. A 1988 Pediatrics study reviewed 60 cases of what was dubbed “hair-thread tourniquet syndrome.” Of those, 24 incidents involved toes, 14 involved fingers and 22 painful incidents reported hair wrapped around babies’ genitals, including tiny penises.

    As recently as this year, the Hong Kong Journal of Paediatrics reported the case of a 2 1/2-month-old girl whose right fourth toe was inexplicably blue and swollen -- until doctors detected an errant hair and removed it. 

    Lepore says he’s seen only three cases in his 30 years of practice. But he’s still on alert for the syndrome any time he sees a baby with a discolored toe or other digit.

     “You’ve got to have a persistent paranoid suspicion whenever you see something that doesn’t look right -- like a blue or a red toe,” he says. “And you can’t let people blow you off. If your kid’s toe is blue there’s got to be a reason.”

    The danger, if your doctor doesn’t recognize toe tourniquet syndrome, is that your baby could lose a toe, Lepore says. Don’t be afraid to mention toe tourniquet syndrome to the doctor if that diagnosis doesn’t get consideration, he adds.

  • Nearly 20 percent of teens admit to 'sexting'

    By Jeanna Bryner
    LiveScience

    Despite knowing the consequences, many teens still send sexually explicit photos to others using their cellphones, a new study on sexting suggests. 

    Often defined as sending nude or seminude photos, or sexually explicit text messages, the prevalence of sexting seems to be hard to pin down, with estimates ranging from approximately 1 percent to 20 percent of kids. The discrepancies between the numbers may have to do with how researchers define sexting (some researchers include texts, while others tally just sexual images) and how they separate different age groups, among other factors.

    In the new study, Donald Strassberg, of the University of Utah, and colleagues defined sexting as sending sexually explicit photos and included freshmen through seniors in high school. They surveyed 606 students from a private high school in the U.S. Southwest, asking them about their experiences sexting and their understanding of the consequences if caught. Students also indicated their views on sending sexually explicit photos over cellphones.

    Nearly 20 percent of participants (18 percent of male students, 17 percent female students) reported having sent a sexually explicit image via their cellphone, with nearly twice as many saying they had received such a cellphone picture.

    And while nearly 50 percent of male students had received a sext, only 31 percent of females reported the same. Of those receiving such a picture, about 25 percent said they had forwarded the sexy photo to others.

    The photo wasn't necessarily one of the sender, with more than 8 percent of participants saying they had sent a sexually explicit photo that they took of someone else to a third party, with guys (11.8 percent) more likely than gals (4.5 percent) to have done so.

    More than one-third of those students who indicated sexting said they were aware of serious legal and other consequences of getting caught. As expected, those who had sent a sext were more likely than peers to find sexting acceptable.

    When asked what consequences, if any, there should be if caught sexting, the most common response, given by 21 percent of participants, was "no consequence." Other relatively common responses included: removal of phone privileges (8 percent); school suspension or expulsion (4 percent); pornography charges (2 percent); jail (5 percent); sexual harassment charges (2 percent); community service (25 percent); and a fine (7 percent). [ Infographic: Consequences of Teen Sexting ]

    Currently, sexting laws differ by state, but the researchers noted that in many states, those sending or receiving nude pictures of someone under 18 (including themselves) risk charges as serious as possession or distributing child pornography.

    The authors conclude: "These results argue for educational efforts such as cellphone safety assemblies, awareness days, integration into class curriculum and teacher training, designed to raise awareness about the potential consequences of sexting among young people."

    These findings are published online in the journal Archives of Sexual Behavior.

  • Diabetes drug may lower breast cancer risk

    By Rachael Rettner
    MyHealthNewsDaily

    A diabetes drug may reduce the risk of breast cancer in some women, a new study suggests.

    In the study, postmenopausal women with diabetes who took the drug metformin to control their blood sugar were 25 percent less likely to have breast cancer after 11 years, compared with diabetes-free women who did not take the drug.

    Moreover, diabetic women in the study who took drugs other than metformin were slightly more likely to have breast cancer, compared with diabetes-free women of a similar age. (Studies have suggested a generally increased risk of breast cancer among women with diabetes, though not all research has shown this to be the case.)

    The findings held even after the researchers took into account factors that could affect the participants' risk of breast cancer, such as their body mass indexes (BMI), physical activity levels, and how frequently they received mammograms.

    The study adds to a growing body of research showing that the drug may have anti-cancer properties. A few previous studies have noted lower rates of breast cancer and pancreatic cancer among women with diabetes who take the drug. And studies in animals and on cells in lab dishes have suggested the drug may inhibit cancer cell growth.

    However, the new study found an association, and not a cause-effect link, and so more research is needed to confirm the findings. Results from an upcoming trial sponsored by the National Cancer Institute will be part of that evidence, said Dr. Iuliana Shapira, an investigator at the Feinstein Institute for Medical Research in Manhasset, N.Y., who was not involved in the study. In the trial, women with early stage breast cancer, who don't have diabetes, will be randomly assigned to receive either metformin or a placebo, and will be followed for five years, Shapira said.

    In the new study Dr. Rowan Chlebowski, of the UCLA David Geffen School of Medicine, and colleagues analyzed information from more than 68,000 postmenopausal women who participated in the ongoing study called the Women's Health Initiative, and were followed for an average of 11.8 years.

    Over the study period, 11,290 women were diagnosed with diabetes, and 3,273 were diagnosed with invasive breast cancer.

    It's not clear how metformin might reduce breast cancer risk, but the drug is known to increase the activity of an enzyme called AMP Kinase, Shapira said. This enzyme is an "energy sensor" for cells, Shapira said, and an increase in its activity may cause cancer cells to die by committing cellular suicide.

    Metformin is not prescribed only for diabetes, it is also given to women with a condition known as polycystic ovary syndrome. A goal of future research is to see whether the drug could be given to women at risk for breast cancer as a way to prevent the disease, Shapira said.

    The study was published on June 11 in the Journal of Clinical Oncology.

  • Too little vitamin D may explain black Americans' cancer deaths

    By Christopher Wanjek
    LiveScience

    African-Americans are 25 percent more likely to die from cancer than white Americans are, and the reasons are numerous, including lower socio-economic status, poorer access to health care, and the cancer diagnosis coming at later, more deadly stages.

    Still, health experts say these factors cannot fully explain the extent of disparities in survival for the most common cancers, such as breast, lung, colon and prostate cancers.

    A paper published in the current issue of the journal Dermato-Endocrinology points the finger at a seemingly obvious but overlooked culprit: the sun.

    The researchers' theory is that, in northern latitudes, the dark skin of African-Americans cannot absorb enough sunlight to generate adequate amounts of vitamin D, which is often called the "sunshine vitamin." The body uses ultraviolet rays from the sun to manufacture vitamin D in the inner layers of the skin.

    Vitamin D is needed for strong bones; doctors nearly 100 years ago associated a lack of adequate sun exposure with rickets among child laborers, exemplified by bowed legs. Recent studies also have shown that low levels of vitamin D in the blood seem to contribute to a weak immune system and a host of diseases, such as cancer and multiple sclerosis. [ Infographic: The Power of Vitamin D ]

    This lack of vitamin D could completely fill in the health disparity gap for cancer survival between white and black Americans, the researchers said.

    Previous work by geneticist Rick Kittles at the University of Chicago suggests that upwards of 75 percent of African-Americans are deficient in vitamin D. Kittles says that African-Americans living north of the 37th parallel — just about anyplace north of central California, Texas, Tennessee or North Carolina — will have difficulty through most of the year absorbing enough sunlight to make vitamin D, because of the low angle of the rays reaching the Earth's surface.

    Given this largely established fact, researchers Alan Peiris of East Tennessee State University and William Grant of the Sunlight, Nutrition and Health Research Center in San Francisco set out to look for a correlation between vitamin D and cancer death disparities. (In past research, Grant and a colleague suggested low levels of ultraviolet-B rays in Austria, paired with Mozart's nocturnal habits, may have led to vitamin D deficiency in the composer, who died at the age of 35.)

    What they found in the new study is preliminary but warrants further investigation, they said. Relying solely on a scientific literature review, the researchers found that low vitamin D is independently associated with each of the cancer types for which an unexplained health disparity exists between African-Americans and white Americans.

    Specifically, they found lingering disparities for 13 types of cancer after accounting for socioeconomic status, stage at diagnosis, and treatment: bladder, breast, colon, endometrial, lung, ovarian, pancreatic, prostate, rectal, testicular, and vaginal cancer; Hodgkin's lymphoma; and melanoma. For each one, there is a vitamin-D connection.

    Few scientific studies have directly explored the link between cancer deaths and low vitamin D levels in African-Americans, though. One study published in the journal Cancer in 2011 indeed found that vitamin D deficiency contributes to excess African-American mortality from colon cancer. A Harvard study published in Cancer Epidemiology, Biomarkers and Prevention in 2006 found that African-Americans who are at risk for low vitamin D also had a higher risk for cancer death, particularly for digestive-system cancers.

    The paucity of studies makes this a ripe topic for exploration, said Grant. If low vitamin D is the cause of this disparity in cancer deaths, thousands of lives could be saved annually by encouraging African-Americans to take a daily vitamin D supplement in the range of 1,000 to 4,000 IUs, he said. [ 9 Good Sources of Vitamin D ]

    Peiris added that monitoring vitamin D levels should be routine. The issue becomes critical given that passive exposure from the sun simply is not enough for millions of African-Americans living in northern cities such as Washington, New York and Detroit. Air pollution filters sunlight, too; and many African-American children stay indoor for long hours, sometime over concerns of neighborhood safety.

    Obtaining enough vitamin D through food, regardless of one's skin tone, can be difficult. Sources include fatty fish such as salmon, mackerel and wild catfish. At least the sources, aside from cod liver oil, tend to be tasty.

  • Man's microbes help map 'normal' in healthy humans, NIH research finds

    Photo courtesy Charles Rathmann

    Charles Rathmann, 40, a St. Louis research director was the first of 242 volunteers accepted for a research project that collected samples of their cells to map the microbial make-up of healthy humans.

    Charles Rathmann never thought of himself as a model for American manhood, but when it comes to the bugs on his body, he is.

    The 40-year-old St. Louis research director is among 242 volunteers whose skin, nose, mouth, gut and other samples have been collected and analyzed to create what scientists are celebrating as the first map of the normal microbial make-up of healthy humans.

    “I am an ordinary guy,” Rathmann told msnbc.com. “But they can use the normal flora on my body to set a baseline.”

    Indeed, the release of coordinated research Wednesday from the Human Microbiome Project Consortium organized by the National Institutes of Health promises to revolutionize the study of the microorganisms that inhabit people, experts told reporters.

    "This is a whole new way of looking at human biology and human disease," said Dr. Phillip Tarr, a researcher and professor of pediatrics at the Washington University School of Medicine. "It's awe-inspiring and it also offers incredible new opportunities."

    Instead of the one-germ, one-disease theory that has governed past thinking, doctors and patients alike will need to consider the entire ecosystem of bacteria at work in the body, much like the ecosystem of a forest in nature. 

    "This is going to be a whole new ballgame," Tarr added. 

    Scientists are just starting to use the new HMP data to understand disease, including the role of the gut microbiome in maladies such as Crohn's disease or ulcerative colitis, the skin microbiome in psoriasis, and the urogenital microbiome in reproductive and sexual diseases, among many other projects, experts said. It could become crucial in figuring out remedies for serious and potentially deadly C. difficile infections, which are blamed on disruptions in the normal flora of the gut, Tarr said.

    Scientific reports being published this week include two in the journal Nature and 12 in journals from the the Public Library of Science or PLoS. The reports represent work from some 200 members of the HMP Consortium from nearly 80 universities and scientific institutions reflecting five years of research, according to the NIH.

    For the first time, researchers used sophisticated genome sequencing techniques to find that instead of the few hundred bacterial species previously identified through laborious cultures, there are more than 10,000 microbial species inhabiting the human body.

    Microorganisms outnumber human cells 10 to 1 and they make up between 1 percent and 3 percent of the body’s mass, the researchers found. In a 200-pound adult, that means there are between 2 pounds and 6 pounds of bacteria, "a rather remarkable amount," said Dr. Eric D. Green, director of the National Human Genome Research Institute. 

    The new data, which will provide a shared database for the scientific community, showed that people harbor a whole range of microbes, including beneficial bugs and also pathogens known to cause disease. The microbes in healthy people appear to be much more diverse from site to site than expected, and also from person to person, researchers found. In addition, they were surprised to learn that the specific bacteria at a site are less important than the functions they perform. 

    "It appears that bacteria can pinch-hit for each other," Curtis Huttenhower, a researcher at the Harvard School of Public Health explained in a statement. He was co-lead author of one of the HMP papers published in the journal Nature. 

    Information like that is exactly why Rathmann agreed to be scraped, poked and prodded for science.

    “I liked the fact that this was going to be a way for them to learn more about these little bacteria that exist invisibly on us,” he said.

    Researchers collected a total of 5,298 samples, plucking them from up to 18 body sites of Rathmann and the other volunteers, including 129 men and 113 women, from Houston and St. Louis.

    This gut bug, the bacterium Enterococcus faecalis, is among those analyzed through novel genome sequencing techniques as part of the Human Microbiome Project Consortium coordinated by the National Institutes of Health.

    Participants included some of Rathmann’s friends and colleagues, even his ex-wife, in part because Rathmann’s actual job is to round up subjects for clinical trials at the Washington University School of Medicine.

    “My group tries to recruit volunteers,” said Rathmann, who is director of the Recruitment Enhancement Core at the WUSM Center for Clinical Studies.

    “We get involved any time we see a trial that is interesting. It helps move the medical community forward.”

    In this case, Rathmann and the others had to prove they were healthy, undergoing screening tests, blood tests, even dental exams to make sure their microbes weren’t unusual.

    “If you had a cavity, you were out,” he said. “You could take no medicines that would disrupt the flora they were trying to identify.”

    The samples were collected over a period of several weeks starting in 2009, when Rathmann and others had to agree to use study-issued shampoos, soaps and toothpastes during the testing period.

    The actual collection of the microbes was simple and not painful, Rathmann said. It involved scraping cells from 15 sites in men and 18 sites in women, who had vaginal swabs taken from three places.

    “It was the mouth, teeth, back of the throat, inside of the elbow, back of the ear,” Rathmann recalled. “You also had to give a stool sample on two or three different occasions.”

    Researchers took these samples, all from adults ages 18 to 40, then analyzed them using a novel genetic sequencing technique that was able to identify the DNA of bacteria, ignoring the normal human DNA.

    Using computers, the scientists sorted 3.5 terabytes of data to get a full picture of the human microbiome, the collection of microorganisms living in the human body.

    What they found was riveting, reported the scientists, who figure they’ve now identified between 81 percent and 99 percent of all genera of microorganisms in healthy adults.

    One paper published in PLos ONE found that there were certain core bacteria present in 95 percent of all subjects. But even among those core bacteria, there was a wide range among sites -- and among people. 

    "Our findings include the fact that humans carry a remarkable range of microbes," said Bruce Birren, director of the Genomic Sequencing Center for Infectious Diseases. "Apparently there are many different ways to be healthy when it comes to our microbes."

    Launched in 2007, the HMP has been funded through $153 million from the NIH Common Fund, which invests in high-impact research, and another $20 million from individual NIH institutes and research centers. 

    Until today, Rathmann had not seen any of the research associated with his body samples. Participants didn’t receive maps of their individual microbiomes and they have no idea what particular bugs they harbored in various places.

    “I definitely will follow the results of this,” said Rathmann, who hopes his example will prompt others to volunteer for clinical trials. “Our flora will be the benchmark now for what everybody studies.”

  • Not-so-sexy CPAP can boost men's sex lives, study finds

    Koshy Johnson / Getty Images

    The mask-and-hose contraption known as a CPAP machine may not look alluring, but the relief it provides for sleep apnea can help improve erectile dysfunction and boost users' sex lives.

    A CPAP device, the Darth Vader-like mask used to ease breathing in sleep apnea sufferers, might be the least attractive thing a man can wear at night, but it could wind up improving his sex life, according to a new study released today at an annual meeting of sleep experts.

    In yet another example of how the human penis can serve as an important health indicator, a team of doctors from the Sleep Disorders Center of the Walter Reed National Military Medical Center has found that erectile dysfunction is common in younger men with sleep apnea, but that E.D. -- and libido -- improves in men who use the CPAP, or continuous positive airway pressure machine.

    They presented their results today at the meeting of the Associated Professional Sleep Societies in Boston.

    Over the past few years, medical science has repeatedly shown that how a man’s penis is working can reflect how the rest of his body is working. E.D. can be an early sign of diabetes, cardiovascular disease, high blood pressure and poor fitness, among other ailments.

    So when army captain Dr. Joseph Dombrowsky looked at a small handful of studies that had linked apnea to E.D., he realized that he had access to a pool of possible test subjects -- military beneficiaries newly diagnosed with the sleep disorder -- that he could use to explore the link.

    Dombrowsky and his colleagues recruited 92 men with an average age of nearly 46 who had both a new diagnosis of obstructive sleep apnea, or OSA, and who were starting therapy with CPAP machines.

    The CPAP is a mask-and-tube contraption that few might call sexy. Worn during sleep, it sends a steady flow of air through the mask into breathing passages to keep airways open and restore depleted oxygen levels. It’s the most common and effective treatment for OSA, which occurs when tissue in the back of the throat collapses during sleep, blocking air, disrupting sleep and boosting the risk of health problems such as heart disease and stroke.

    The men in the study averaged 38 apnea events per hour, Dombrowsky found. That’s pretty bad. Severe apnea is defined as 30 or more such events per hour.

    Using a well-established sexual function survey, 43.5 percent of the men reported erectile dysfunction. Unlike previous studies, the E.D. was broken down into three varieties: mild, moderate and severe. The men were reassessed at one-, three- and six-months of CPAP therapy. 

    Dombrowksy was looking for what he called “minimal clinically important differences” of CPAP use.

    “That’s not just a change in a score, a statistic,” he explained in an interview, “but a difference patients really notice and will appreciate.” 

    More than half of patients with mild E.D., or some 54 percent, noticed an improvement after CPAP use. Nearly 29 percent of those with moderate E.D. improved, and more than 27 percent of those with severe E.D. saw a boost. Sexual desire also tended to improve, Dombrowsky found.

    Drugs like Viagra have been shown to work more powerfully to improve E.D. than CPAP therapy, but  Dombrowsky speculates that by starting CPAP before the condition gets worse, some men might be able to skip the pills. 

    While stressing that he was speaking for himself, not for his research team, the army, or the U.S. government, Dombrowsky said he believes that CPAP therapy might be a good early therapy for E.D., particularly in younger men.

    “What the results say to me is that E.D. is a progressive disease, as is sleep apnea. So if we were to intervene earlier, we might be able to stave off the progression of erectile dysfunction.”

    His study raises the issue of why apnea might lead to E.D. in the first place. The most obvious explanation is that the link is related to the way apnea creates low oxygen levels in the blood. But that may or may not be correct. Dombrowsky pointed out that during REM sleep, men get erections in something like a nocturnal workout of penis plumbing. Because apnea interferes with REM sleep, fragmenting sleep patterns, penises may not be getting this workout, leading to dysfunction.

    Dombrowksy said he plans to continue the work with larger numbers of men in hopes of answering some of these questions.

  • MRI, CT scan use spikes, study finds. Should we be worried?

    The latest medical images can provide spectacular pictures, giving doctors and patients enormous amounts of information about a wide range of medical conditions. But doctors may have gotten overly enthusiastic about using them.

    A study out Tuesday in the Journal of the American Medical Association found that the number of MRIs quadrupled, CT scans tripled and PET scans went up 57 percent between 1996 and 2010. The researchers tracked up to 2 million members of six large health systems in the U.S.

    There is no question that before performing a surgery, for example, a doctor wants to see as much as possible. Magnetic Resonance Imaging (MRI) uses magnets and radio frequency fields to scan the body and help doctors make diagnoses of tumors, torn ligaments or strokes without surgery. A PET, or positron emission tomography, scan can be conducted alone or combined with MRI with radioactive isotopes to show metabolic activity in the body such as cancer.  

    The images help; the question is just how much.

     “The increase in use of advanced diagnostic images has almost certainly contributed to both improved patient care procedures and outcomes, but there are remarkably few data to quantify the benefits of imaging,” radiology professor and lead author Dr. Rebecca Smith-Bindman from the University of California, San Francisco, and her colleagues write.

    Why does it matter? The biggest reason is cost. Americans now spend an estimated $100 billion a year on medical imaging. For each patient, each procedure can cost between a few hundred and several thousand dollars. Usually doctors order them for the best of reasons, but sometimes it is defensive medicine based on the fear of lawsuits or, even worse, the need to amortize the huge cost of a piece of equipment the practice has purchased. 

    Another major downside of increased imaging is the “false positive,” which is the discovery of a growth or other apparent problem that presents no danger but needs to be removed -- with additional cost and anxiety.

    The biggest danger with scanning comes from CT, or computed tomography. A CT scan exposes the patient to huge amounts of X-rays. One CT scan of the chest, for example, zaps a patient with the same amount of radiation as 150 old-fashioned X-rays. In their survey of medical records, the authors of the latest study found that 3.9 percent of patients were receiving an exposure or more than 50 millisieverts every year. In comparison, that is about the equivalent of the one-time amount that the Japanese government estimates that the nearby residents of the Fukushima power plant got in the hours before they evacuated.

    A recent Institute of Medicine report on risk factors for breast cancer listed chest CT scans high on the list. Last week, an international study found that children who get CT scans have a slightly higher risk of later developing leukemia and brain cancer. While the absolute risk of cancer is still small, the British researchers suggested minimizing radiation exposure as much as possible.

    In a separate report released by the UCSF researchers Monday, Smith-Bindman said a woman should ask her doctor these questions before getting a CT scan:

    • Is this scan absolutely necessary?
    • Is it necessary to do it now?
    • Are there alternative tests?
    • How can I be sure the test will be done in the safest way possible?
    • Will having the scan information change the management of my disease?

    For the sake of our pocketbooks and peace of mind, we all might be well advised to ask our doctors the same questions about any medical scan we receive.

  • Researchers criticize new study questioning same-sex parenting

    By Stephanie Pappas
    LiveScience

    A new study claiming to find disadvantages for children raised by same-sex parents is attracting criticism from social scientists, who say that the research does not actually address how well gay and lesbians parent.

    The research surveyed almost 3,000 18- to 39-year-olds. Most were raised by heterosexual parents, but 175 had mothers who at one point had same-sex relationships and another 73 of whom had dads once in same-sex relationships. The results suggested that children of these parents are more likely than kids in other family structures to be on public assistance, unemployed or in therapy as adults, among other negative outcomes.

    The study found "that the scholarly and popular consensus that there are no notable differences between the children who grew up with a mother or father in a same-sex relationship and those whose (heterosexual) mother and father were and are still married is a fiction," study researcher Mark Regnerus, a sociologist at the University of Texas, told LiveScience.

    Strong criticism
    But other scientists say the research is deeply flawed, and does not measure the effect of same-sex parenting at all. The study defined same-sex parenting by asking participants if their parents had ever had same-sex relationships, and whether they had lived with the parent at that time. That led to a "hodgepodge" group of people who Regnerus then compared with kids in stable, married homes, said Judith Stacey, a sociologist at New York University who was not involved in the research. 

    "He doesn't have an actual category of gay parents in the project that you can isolate and say the most important thing in this kid's childhood is that they were raised by gay parents," Stacey told LiveScience. "These are kids whose parents, maybe they divorced, maybe they separated, maybe they had a scandalous affair, we just don't know."

    In contrast, a fair comparison would have matched up children of same-sex parents with children of heterosexual parents who looked otherwise similar — no extra divorces, no extra separations, no extra time in foster care for the kids, said Gary Gates, a researcher at the Williams Institute, a sexual orientation policy think tank at the University of California, Los Angeles.

    Instead, Regnerus categorized all people who said their parents were once in a same-sex relationship in the same group, even if those people had also experienced major childhood upheavals. About half of the people whose parents had ever been in gay or lesbian relationships also said their parents had once been in a heterosexual marriage, suggesting that a great many of these children were the products of a heterosexual relationship in which one parent later came out as gay or bisexual. Fifty-eight percent of those raised by moms who'd indicated a lesbian experience said their mother once left the household during their youth, and 14 percent said they'd spent time in foster care. 

    "All he found is that family instability is bad for children and that's hardly groundbreaking or new," Gates, who was not involved in the research, told LiveScience.

    "What I find most frustrating is that from what I could tell, he could have used his data to test the way I'm suggesting the test, and he chose not to," Gates added. "He intentionally chose a methodology that is absolutely primed to find bad outcomes in those kids." 

    Regnerus said he plans to look more closely at the experiences of the same-sex parented kids in an upcoming article. 

    "A detailed exploration of who lived with whom, when, for how long, etc., was not the point of this study," he said. 

    Where same-sex parenting stands
    Regnerus detailed his findings Sunday in the journal Social Science Research, alongside several commentaries on the work. The study was funded by two conservative-leaning foundations, Witherspoon Institute and the Bradley Foundation, though the funders had no control over the study design, interpretation or conclusions, Regnerus wrote. 

    Only two of the 1.7 percent of respondents who reported a parental same-sex relationship reported living with that couple as parents for their entire childhood, meaning that the study has little to say about gay couples who deliberately chose to parent children through donor insemination, surrogacy or other means. 

    Researchers are increasingly studying these parents, Stacey said, and research both in the U.S. and abroad consistently shows that the kids are just fine. 

    "We know that when we compare same-sex couples who are parenting by choice with heterosexual couples who are biological parents, the lesbian couples do really, really well," Stacey said. (Fewer studies have been done on gay men who become parents.) 

    Many of the studies on gay parenting have limitations, such as focusing more on moms than dads, Gates said. But the fact that they overwhelmingly conclude that kids of gay parents turn out fine on the whole is "persuasive," he said. 

    In a commentary published alongside Regnerus' paper, Pennsylvania State University sociologist Paul Amato put it another way. 

    "If growing up with gay or lesbian parents were catastrophic for children, even studies based on small convenience samples would have shown this by now," Amato said. 

    Political fallout
    Regnerus himself told LiveScience that he doesn't believe his study speaks to the politics of same-sex marriage. Nevertheless, the research has been cast in that light, showing up in a New York Times op-ed piece by Ross Douthat suggesting that the article is a case for caution in legalizing gay unions. By the same token, Slate writer William Saletan argued that the research makes a case for gay marriage in order to promote stable same-sex relationships for the sake of the children. 

    Scientists, however, say that both uses of the research reach too far, given the fuzzy definition of same-sex parenting in the survey.   

    "I don't think it's the kind of study to lead you to any policy position, frankly," Stacey said.

  • Insurer embraces some Obamacare provisions

    Citi has upgraded hospital stocks, with Gary Taylor, Citi analyst and the FMHR traders.

    Updated at 7:40 p.m. ET: UnitedHealth Group's plan to continue offering some elements of the Affordable Care Act regardless of the fate of the legislation is a political as well as a business decision.

    While people — especially young adults and people suffering from expensive or chronic illnesses — will benefit from the insurance giant's initiative, the company reaps a public relations coup that will increase its costs by as little as one or two percent, one analyst said. 

    "It makes UHG attractive among employees and, hence, employers," Uwe Reinhardt, professor of economics and public affairs at Princeton University, said via e-mail. 

    In a statement Monday, UnitedHealth Group said its UnitedHealthcare company will preserve a few popular aspects of the new healthcare law that have already been put into place even if the Supreme Court strikes down all or part of the ACA. It will continue to let young adults stay on their parents' policies until they turn 26, not charge co-pays for some preventative health services and waive lifetime coverage dollar caps, along with provisions related to appeals and policy termination. 

    "I think the company sees the opportunity to score some political points by standing behind these very popular aspects of the law," said Matthew Coffina, an analyst at Morningstar. Coffina pointed out that since the company is already offering these services as required by law, the costs of providing them has already been incorporated into premium prices. 

    Later Monday, Humana said it would continue those same provisions, according to Kaiser Health News. Aetna, too, said it would retain the young adult provision, the preventive care benefits and a third-party appeals program. The  Aetna announcement did not include a reference to lifetime limits on coverage. 

    "The protections we are voluntarily extending are good for people’s health, promote broader access to quality care and contribute to helping control rising health care costs," UnitedHealth Group president and CEO Stephen J. Hemsley said in a statement. "These provisions make sense for the people we serve."

    It might seem strange that insurance companies — an industry known for aggressive cost-cutting tactics — only are now getting around to realizing the potential savings in services like free diabetes and blood pressure screenings. 

    "Sheer inertia can explain it," Reinhardt said. "It would be a mistake to assume that private health insurers are particularly visionary or innovative in this regard." 

    Insurance companies haven't traditionally been motivated to provide this kind of service because it hasn't been demanded by companies. A majority of Americans are still insured through their workplaces, although that number is falling. But since people rarely stay with one employer for their entire careers, there's little economic incentive for a company to make long-term investments in workers' health.

    Coffina said the intense political debates about healthcare issues have prompted Americans and insurance companies alike to think more about long-term trends and ramifications. "Reform legislation frames what's expected of these companies and what a minimum level of service is," he said.

    The provision allowing young adults to stay on their parents' insurance is particularly popular, and has been widely used. An April poll conducted by the Kaiser Family Foundation found that 71 percent of Americans support the provision, and nonprofit group the Commonwealth Fund calculated that 6.6 million people between the ages of 19 and 25 were able to obtain health insurance as a result.

    Some Republican lawmakers — who are unified in their opposition to the health reform law — have conceded that this is a good idea, and it's politically popular enough that rejecting it could be political suicide. Bloomberg reported last week that Rep.Phil Gingrey, R-Ga., co-chair of the GOP Doctors Caucus, called the young-adult provision “a good policy," although the Caucus advocates a "complete repeal" of the Affordable Care Act on its website. 

    If health insurers expect that lawmakers will require them to provide certain services even if the Supreme Court strikes down the law, preempting that by volunteering compliance is a shrewd maneuver. "It seems like they're trying to get ahead of their competitors," said Igor Volsky, deputy editor of left-leaning blog ThinkProgress.org. "I wouldn't be surprised to see others echo it."

    Some other insurers have already weighed in. The CEOs of Aetna and Humana both acknowledged in recent interviews that popular provisions such as young adult coverage might be already too ingrained in the system to roll back, according to the Wall Street Journal

    Even if legislation doesn't force their hand, taking away benefits is an unpalatable choice for insurance companies because it makes them look like the bad guys. "It's going to be very hard, regardless of what happens with the [Supreme Court] decision, for insurance companies to take away benefits," Volsky said. "I think once you grant people certain benefits, it's very difficult to move backwards." 

  • 'GMA' host Robin Roberts battling blood disorder

    Robin Roberts

    By Lisa Flam

    “Good Morning America” anchor Robin Roberts made some news of her own today: She’s been diagnosed with a rare blood and bone marrow disease called myelodysplastic syndrome (MDS), a condition once known as pre-leukemia.  Roberts, a breast cancer survivor, said she received the diagnosis several months ago and will receive a bone marrow transplant from her older sister later this year. “My doctors tell me I’m going to beat this – and I know it’s true,” she wrote when she announced her diagnosis.
                                                                                                   
    MDS is a pre-cancerous disorder half way between benign and malignant, said Dr. Martin Tallman, chief of the leukemia service at New York’s Memorial Sloan-Kettering Cancer Center. It occurs when the bone marrow produces blood cells that break apart and disintegrate when they enter the blood stream.

     “When the marrow produces blood cells, they’re cracked, they’re fragile and faulty and they disappear, he said.  Those disappearing blood cells leave patients with a low blood count, Tallman told msnbc.com, which can leave patients feeling fatigued from anemia, susceptible to infections like pneumonia and suffering from internal bleeding. The condition is curable, though it can also lead to fatal complications, primarily through infection, and some MDS patients develop leukemia. 

    MDS is more common in people over 60, and in most cases, doctors don’t know why they developed the disorder, though genetic changes that take place as people get older are thought to be the cause. A minority of MDS patients develop the disorder following chemotherapy for cancer treatment.

     “Sometimes treatment for cancer can lead to other serious medical issues and that’s what I’m facing right now,” Roberts said on the air this morning, noting that she beat breast cancer five years ago.  Tallman explains that as chemotherapy drugs are killing cancer cells, they can also cause genetic changes in healthy cells, which can lead to what’s called treatment-related MDS. “We are able to cure certain disease but we pay a price,” he said.

    About 12,000 people a year are diagnosed with MDS in the U.S. each year, according to the American Cancer Society. The number of cases of MDS is rising, according to the Memorial Sloan-Kettering website, because there is a growing population of older people, and because patients are living longer after being treated for their first cancer.

    For years, patients with MDS were treated with antibiotics and blood transfusions, but three new types of chemotherapy drugs to fight MDS became available starting in about 2004, said Tallman, a hematologist-oncologist. They are effective in about 30 percent to 40 percent of patients, he said. Some patients don’t require treatments at all and can live with the disease; others are cured with the chemotherapy drugs alone. The only proven cure for MDS is a stem cell transplant, Tallman said, describing what it also called a bone marrow transplant.

    Roberts says she is beginning a pre-treatment regimen of chemotherapy today before undergoing the bone marrow transplant. Her doctors gave her a good outlook, she wrote.

    “They say I’m younger and fitter than most people who confront this disease and will be cured.”

    Tallman says that most patients are not cured of MDS but their prognosis depends mostly on the kinds of genetic changes taking place in their blood cells and the availability of a stem cell donor. While being younger and fitter than most patients should help a patient’s chances of a cure, he called those “soft” factors.

    A transplant is a big undertaking, Tallman says, and patients can’t have the procedure if they are older or too sick. Patients who have the transplant spend about four weeks in the hospital, he said, to be monitored for infection and bleeding.

    The biggest risk from such a transplant is graft vs. host disease, in which the stem cells reject their new home and attack the host body, Tallman says. Also, the disease can come back after a transplant.

    In a transplant, patients receive chemotherapy, sometimes with radiation, to kill the bad cells, which are then replaced with an infusion of healthy stem cells, said Tallman.

    “They go on to repopulate the bone marrow with healthy blood cells,” Tallman said. “It’s like replanting a garden with stem cells. You plant. You wait and then the flowers will start growing.”

     

    A new study from researchers at the MD Anderson Cancer Center examined 300 women with early stage, untreated breast cancers and drew blood to search for the presence of circulating tumor cells in the bloodstream. NBC's Dr. Nancy Snyderman reports.

  • Cutting compulsion affects kids as young as 7, study finds

    By Linda Carroll and Diane Mapes

    The Tacoma, Wash., mom knew something was up with her 11-year-old daughter when the girl kept leaving school with stomach aches that disappeared as soon as she got home. But she didn't know how bad things had gotten until the school called one day two years ago to tell her the sixth grader was sobbing and threatening to hurt herself.

    “I told the principal 'I'll be right there,” says Abby, a 34-year-old special education teacher from Tacoma, Wash., whose last name is being withheld to protect her daughter. "When I got there, they'd already called the paramedics. That's when she told me, 'Mom, I've been cutting myself.'”

    Abby was shocked to learn her daughter had been using the family's steak knives to deliberately cut herself on half dozen occasions. But, as it turns out, her story isn’t as unusual as we'd like to think.

    A sobering new study of 665 kids between the ages of 7 and 16, found that a full 9 percent of girls and almost 7 percent of boys surveyed have engaged in self-injurious behaviors such as cutting, banging their heads or hitting themselves.

    In fact, researchers found that kids as young as 7 were harming themselves as a way of dealing with unbearable psychic pain. The study of kids in third, sixth and ninth grades found that 7.6 percent of 3rd graders and 12.7 percent of 9th graders surveyed engaged in what researchers called nonsuicidal self-injury.

    "Most people think of kids in elementary school as happy-go-lucky,” says Benjamin  Hankin, an associate professor of psychology at the University of Denver and the co-author of the study. “They don’t expect kids this young to be having these kinds of problems.”

    And, says Hankin, there are signs that self-injurious behaviors may be on the rise among younger kids. While there aren’t hard statistics, “anecdotally, you talk to parents, teachers, and other professionals and they say that it’s definitely on the rise,” he adds. 

    Many experts believe that kids who turn to cutting and other forms of self-injury inherited a predisposition to anxiety, depression and other emotional issues. The cutting is a way of dealing with the emotional pain.

    Hankin has other research that points to a mix of genetic and environmental factors.

    “Our data would suggest that the majority of these kids are experiencing really significant environmental stress, such as peer bullying, peer exclusion, gossip, and relational aggression,” he says.

    Abby says that after talking to her daughter, who was adopted, about her cutting behavior, she learned that the girl was being bullied at school. 

    "She hung out with another girl who wasn't the most popular and she and this girl got made fun of and bullied," she says. "Our daughter had talked to the principal and her teachers, done what she was taught to do, but it wasn't working. And we didn't know the whole story. She had an abusive background with her birth family and stuffing her feelings is second nature with her."

    Dealing with the pain
    For the new study, Hankin and his colleagues found that until ninth grade, boys were almost as likely as girls to injure themselves. But at ninth grade there was a dramatic shift with girls three times as likely as boys to start harming themselves as a way of coping with stress. 

    Experts interviewed by msnbc.com said they weren’t surprised by the findings.

    Kids are feeling pain and they don’t know how to deal with it, says Dr. Jonathan Pletcher, clinical director for adolescent medicine at the Children’s Hospital of Pittsburgh at the University of Pittsburgh Medical Center.

    "It’s a way of coping with stress and anxiety – of inner discordant feelings,” Pletcher goes on. “In a young teen it’s hard to find the words to describe how they’re feeling. They come at this through a process of experimentation. Then cutting becomes a ritual that they build their days around. It’s a way of dealing with all the stress and negative feelings that accumulate during the day.”

    While, as the study shows, some kids start younger, cutting and other types of self- injury often begins in middle school, says Dr. Mark DeAntonio, a clinical professor and director of inpatient child and adolescent services at the Resnick Neuropsychiatric Hospital at the University of California, Los Angeles.

    “It’s a very overwhelming time of their lives,” he explains. “And they develop this as a way of self-soothing. I know it’s a little hard for adults to get their heads around the idea that self-injury can be self-soothing, but I’ve talked to a lot of adolescents and what they say is that it distracts them from psychic pain. And the physical pain is a lot easier to cope with than the emotional pain. It centers them.”

    The self-injury doesn’t have to be dramatic. Some kids will just use a nail file to scratch themselves on the ankle or abdomen, Pletcher says. “It’s a way of calming down the nerves,” he explains.

    Because the physical pain can distract the nervous system, it can lead to calmer emotions, Pletcher says. And because of that, cutting can be a bridge to help kids deal with life until they get the help to develop better coping skills. Experts warn that parents should never just ignore this kind of behavior, hoping it will eventually go away on its own.

    “The biggest mistake a parent can make is assuming they know why the kid is doing it and not challenging the adolescent to say why and what’s going on,” DeAntonio says.

    Copy-cat cutting
    Sometimes, though, the cutting may not be about a deeper meaning.

    “In our American society there is a cultural fad quality to it,” DeAntonio says. “'If you’re not doing this then you’re not a real teenager.' Some feel they have to do it as a rite of passage.”

    And sometimes, it’s a case of copy-cat, experts say.

    “One kid may be doing it and their peers find out and then they may emulate it,” says Dr. Steve Pastyrnak, division chief of pediatric psychology at the Helen Devos Children’s Hospital in Grand Rapids, Mich. “In that case it’s probably a little bit of nature and nurture going on.”

    That might at least partly explain cases where cutting seems to run in a family.

    One San Antonio mom discovered two of her daughters were cutting themselves more than a decade ago, at ages 12 and 13.

    "My older girl would cut herself on her wrists and then cover it up with bracelets and my younger girl would do her hip," says Patricia, a mother of six whose last name is being withheld to protect her daughters’ privacy. "Our older daughter was more outward with the signs. She was more rebellious and more testing of authority but our younger girl didn't show those signs until ninth grade. She was following our older daughter."

    She says she finally saw the marks on her older daughter's wrists and confronted her about it, trying to find out why she was doing it. Once she discovered the 12-year-old was cutting herself as well, she became even more vigilant.

    Both Patricia and Abby sought therapy for their daughters, who they say no longer cut themselves.

    If parents suspect their child is cutting, they should have a conversation to try to find out exactly how dangerous the situation is and if the child needs help, says Hankin. If that's out of the question, however, he suggests parents try to get them to talk to someone else.

    “What we would encourage you to do is to follow your gut,” he says. “And if you don’t want to have a conversation about this with your child, then let them have it with the pediatrician or a nurse or a school counselor. They can comfort the child with the fact that the conversation is confidential so the child is more likely to talk. A lot of kids worry that their parents are going to get mad.”

  • Too little sleep? Stroke risk spikes in healthy adults

    A new study from researchers at the University of Alabama at Birmingham found that for healthy, normal-weight people aged 45 and older, getting less than six hours of sleep a night could boost the risk of stroke. NBC's Dr. Nancy Snyderman reports.

    Too few hours of sleep can raise the risk of stroke significantly, even among healthy, normal-weight people, a new study finds.

    Attention, busy middle-aged folks. You may be healthy and thin, but if you habitually sleep less than six hours a night, you still could be boosting your risk of a stroke.

    That’s the surprising conclusion of a new study being presented Monday at SLEEP 2012, the annual meeting of the nation’s sleep experts.

    Getting too little shut-eye appeared to more than quadruple the risk of stroke symptoms among healthy, normal-weight people aged 45 and older, according to a study of some 5,600 people followed for up to three years.

    “The really important take-home message is this: Don’t blow it off. Sleep is just as important as diet and exercise,” said Megan Ruiter, the University of Alabama at Birmingham researcher who led the study.

    Experts recommend that healthy adults get between seven and nine hours of sleep a night. But about one in three U.S. workers regularly gets less than seven hours of snooze time, according to a recent government health report.

    Ruiter and her colleagues reviewed data from some 30,239 people participating in the REGARDS study – Reasons for Geographic and Racial Differences in Stroke – sponsored by the National Institutes of Health.

    Of those, they teased out some 5,666 people who were healthy at the start of the study – no history of stroke, stroke symptoms, so-called “mini-stroke” or transient ischemic attack, or elevated risk for sleep apnea and other sleep-disordered breathing problems.

    “We eliminated all the people who were high risk,” Ruiter said.

    But when they looked more closely at the sleep habits of those people and adjusted for their weight, they found what Ruiter said were unexpected results.

    In people who fell into normal weight categories -- a body mass index of 18.5 to nearly 25 -- those who reported sleeping less than six hours a night were at about 4.5 times greater risk of developing stroke symptoms than whose who slept seven and eight hours a night. Surprisingly, that increase wasn't apparent in overweight or obese people who slept less.

    “Our thought is that habitually sleeping less than six hours is kind of like a precursor,” said Ruiter. “It might kind of lead to some of these stronger and more severe risk factors later on.”

    That’s dismaying news to Mark Wolfe, 49, a busy teacher, husband and father of four from Corvallis, Ore., who has run the Boston Marathon eight times and routinely gets six hours of sleep or less, waking at 4:05 a.m. on weekdays in order to train.

    “Because I’m leading a very active and healthy life, I don’t expect to drop dead from a stroke,” said Wolfe, who is tall and thin, with a BMI of about 21.  

    But there’s no question, adults function best with more sleep than six hours a night, experts say. Chronic sleep deprivation caused by getting too little most nights may boost the risk of stroke because it causes changes in the autonomic functions of the body, including blood pressure, heart rate, inflammation and glucose levels, said Dr. Phyllis C. Zee, associate director for Sleep & Circadian Biology at the Northwestern University School of Medicine.

    “It not only affects the blood vessels to the heart and body, but also to the brain,” said Zee, who was not involved in the study presented at the meeting of the Associated Professional Sleep Societies.

    It will take more research to determine whether short sleep actually results in more full-blown strokes for the REGARDS participants. But in the meantime, Ruiter said the study offers cautions for Wolfe and other middle-aged people who maintain their weight but scrimp on sleep.

    “The important thing now is just to have physicians and people be more aware that the amount and quality of sleep might be important for how they feel and the quality of their health,” she said.

  • Far-flung E. coli outbreak sickens 14 in 6 states

    Cases have popped up in six states, including Georgia, Florida and California. So far, three people have been hospitalized and one little girl has died. NBC's Gabe Gutierrez reports.

    Update, June 22: One additional victim has been confirmed in an outbreak of E. coli O145 infections that puzzled state and federal health officials, bringing the total illnesses to 15 identified in six states. No source of the outbreak has been identified, the Centers for Disease Control and infection said Friday. Because the last illness was detected six weeks ago, the outbreak may be over, but officials said they'll continue to search for sources of the infections.

     

    Federal health officials are investigating a mysterious outbreak of E. coli infections that has sickened at least 14 people in six states, including a 21-month-old Louisiana girl who died.

    No source has been identified for the strain of E. coli O145 genetically linked to illnesses in states as far-flung as Florida and California, officials with the Centers for Disease Control and Prevention confirmed Friday. People became ill between April 15 and May 12. 

    Most of the infections have been reported in Georgia, with five cases, and Louisiana, with four cases, including the death of the child identified as Maelan Elizabeth Graffagnini of New Orleans.

    Two infections with the outbreak strain have been reported in Alabama and one each has been reported in California, Florida and Tennessee. The Florida victim is a 22-year-old woman from Leon County, state health officials said. 

    “This ongoing multi-state investigation has not yet identified a source of those infections,” a CDC statement released Friday said. “The investigation is looking at both food and non-food exposures.”

    Health officials in several states are interviewing ill people to determine how they may have been exposed to the E. coli strain, one of several Shiga Toxin-producing E. coli — or STEC  varieties.

    The most common STEC is E. coli O157:H7, which is the potentially deadly strain commonly linked to ground beef. The strain of E. coli O145 is less common, but can be just as harmful. 

    This week, the U.S. Department of Agriculture began testing certain cuts of commercially produced beef for E. coli O145 and five other STEC strains that have the potential to cause serious illness and death.

    People typically become ill between two and eight days after being infected. Most people develop diarrhea, including watery and bloody diarrhea, and abdominal cramps. Most people get better in a week, but some people including children, the elderly and those with compromised immune systems  can become seriously ill, developing a condition known as hemolytic uremic syndrome, which can cause kidney failure and death.

    While the specific cause of the outbreak remains unknown, health officials recommend several general steps to prevent transmission of illness:

    • Wash your hands after using the bathroom, changing diapers and before eating or preparing food. Wash up also after contact with animals or their environments, including petting zoos, farms, fairs and home backyards.
    • Prevent cross contamination of food by washing hands, counters, cutting boards and utensils after they touch raw meat.
    • Cook meat thoroughly. Ground beef and meat that has been tenderized should be cooked to at least 160 degrees F. Use a meat thermometer to check doneness.
    • Avoid raw milk, unpasteurized dairy products and unpasteurized juices such as fresh apple cider.
    • Avoid swallowing water when swimming or playing in lakes, ponds, streams, swimming pools and kiddie pools.

    A food-borne illness known as toxoplasmosis doesn't grab the headlines the way salmonella or E.coli outbreaks do, but new research suggests that some organic meats may be more likely to carry this parasite, which can then be transmitted to consumers who eat these meats, if undercooked.

    "The new trend in the production of free-range, organically raised meat could increase the risk of Toxoplasma gondii contamination of meat," the authors wrote.

    The researchers point out that eating undercooked meat — whether organic or conventionally raised — especially pork, lamb and wild game such as venison, is one of the main ways people become infected with the toxoplasma parasite.  People can also contract the infection by not washing raw fruits and vegetables, which may have come in contact with soil contaminated by cat feces.

    Cats can spread toxoplasmosis after eating other infected animals and then passing the parasite along in their feces. This can contaminate not only home litter boxes, but the soil or water if a cat goes outside.

    Although perhaps as many as one in five Americans carry the parasite, few people have symptoms because the immune system in healthy people does a good job of preventing T. gondii from causing illness. Toxoplasmosis presents more of a threat to pregnant women and people with a weakened immune system, especially if they change cat litter boxes or touch contaminated soil when gardening.

    In its earliest stages, the illness causes flulike symptoms, and if severe, can cause damage to the brain, eyes and other organs.

    The research was published online May 22 in the journal Clinical Infectious Diseases.

    Organic meat risks

    The new research reviews the foods most likely to carry the parasite, and how people can prevent becoming sickened by it. The foods with the greatest chance of carrying toxoplasmosis parasites in the U.S. include raw ground beef or rare lamb; unpasteurized goat's milk; locally produced cured, dried or smoked meat; and raw oysters, clams or mussels.

    Growing consumer demand for "free-range" and "organically raised" meats, especially pork and poultry, will probably increase the prevalence of T. gondii when people undercook and eat these foods, according to the study's authors, Dr. Jeffrey Jones, of the parasitic diseases branch of the Centers for Disease Control and Prevention, and J.P. Dubey, of the USDA's Animal Parasitic Disease Laboratory. 

    That's because as more pigs or chickens are raised in less confined, more animal- friendly environments, they have greater access to grass, soil, feed or water that may be in contact with infected cat feces, or to rodents or wildlife infected with T. gondii.

    Compared with chickens raised indoors, the prevalence of the parasite in free-range chickens is much higher, anywhere from 17 percent up to 100 percent, in some estimates. (But the risk is low for chicken eggs, the authors noted.)

    Other research has shown that more organically raised pigs have tested positive forT. gondii than conventionally raised pigs. 

    Sheep also have a higher likelihood of being contaminated with toxoplasma, as do game meats such as deer, elk, moose and wild pig. Beef and dairy products have not yet played a main role in transmitting the infection, except for eating raw or undercooked ground beef.

    Keys to prevention

    "Toxoplasmosis in an under-recognized source of food-borne illness and attracts little public attention," said Douglas Powell, a professor of food safety at Kansas State University in Manhattan, Kan. "People are not as familiar with this parasite, so we think it doesn't happen much," he explained.

    Yet, toxoplasmosis is one of five "neglected parasitic diseases" targeted by the CDC as a public health priority.

    By one recent U.S. estimate, toxoplasmosis was the second-leading cause of food-borne illness deaths (salmonella is first), claiming more than 300 lives a year. The parasite was also responsible for more than 4,000 hospitalizations annually, ranking it fourth among food pathogens.

    Cooking meat thoroughly should reduce the risk of becoming infected, Powell said, because parasites are usually found on the insides of animals, not on the meat's surface. He said people should be very careful when eating rare meat, and always verify cooking temperatures with a tip-sensitive digital thermometer placed in the meat's thickest part.

    To prevent getting sickened by toxoplasmosis, the researchers recommended cooking whole cuts of pork, lamb, veal or beef to 150 degrees Fahrenheit, and resting the meat for three minutes before eating it. Ground meat and wild game should be cooked to 160 F or higher, and poultry to 165 F. Microwave cooking may not kill the parasite.

    As consumers shift their eating preferences, whether it's to organic foods or to less-processed foods, the microbial risks are altered, Powell said.  "Whatever food- production system we come up with, some 'bugs' will find a way to adapt and flourish. So the key is continual vigilance."

    While almost 8 percent had attempted suicide nationwide, nearly 16 percent had attempted suicide in Chicago.

    Family: Bullying by 'wolf pack' led to Texas teen's suicide

    Dr. Hector Adames, a Chicago neuropsychologist, pointed to constant digital communication as the problem.

    When rumor, the Internet and school violence fears collide

    "What happens with an increase in communication among students is that there's more pressure. There's more bullying," he said. "When adolescents and children feel embarrassed, it's kind of like the end of the world for them."

    US military suicides rapidly rising even as combat eases

    Adames said it is important for parents to stay involved in their child's lives.

    "It's OK to be vigilant. It's OK to ask questions. And most important: observe, observe, observe. If there's any change, if there's anything different about your child."
