Childhood ear infections may predispose to obesity later in life
 Scientists are reporting new evidence of a possible link between a history of moderate to severe middle ear infections in childhood and a tendency to be overweight during the later part of life. Their study suggests that prompt diagnosis and therapy of middle ear infections one of the most common childhood conditions requiring medical attention may help fight obesity in some people. The findings were presented today at the 236th National Meeting of the American Chemical Society (ACS)........

| New test to diagnose osteoarthritis early
 A newly developed medical imaging technology may provide doctors with a long-awaited test for early diagnosis of osteoarthritis (OA), researchers from New York reported today at the 236th National Meeting of the American Chemical Society. By far the most common form of arthritis, OA is a bane of the Baby Boom generation, causing joint pain and disability for more than half of those over 65 nearly 21 million people in the United States........

| Cervical cancer prevention should focus on vaccination
 The cost-effectiveness of vaccination in the United States against human papillomavirus (HPV), a sexually-transmitted virus that causes cervical cancer, will be optimized by achieving universal vaccine coverage in young adolescent girls, by targeting initial "catch-up" efforts to vaccinate women younger than 21 years of age, and by revising current screening policies, as per an analysis by Harvard School of Public Health (HSPH) scientists in the August 21, 2008 issue of The New England Journal (NEJM)........

| How rheumatoid arthritis causes bone loss
 Scientists have discovered key details of how rheumatoid arthritis (RA) destroys bone, as per a research studyreported in the Aug. 22 edition of the Journal of Biological Chemistry The findings are already guiding attempts to design new drugs to reverse RA-related bone loss and may also address more common forms of osteoporosis with a few adjustments........

| How to stop a new type of heart attack
 PACEMAKERS are supposed to protect people from heart attacks. But to do that they have to provide digital as well as biological security. Earlier this year, a team led by William Maisel at Harvard Medical School demonstrated how a commercial radio transmitter could be used to modify wireless communications from a pacemaker (New Scientist, 22 March, p 23). Doctors normally use these signals to monitor and adjust the implanted device, but a malicious hacker could reprogram the pacemaker to give its wearer damaging shocks, or run down its batteries........

| Alcohol dependence linked to delayed childbearing
 Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has observed that AD in women is linked to delayed reproduction........

| 79 million US adults have medical bill problems
 The proportion of working-age Americans who have medical bill problems or who are paying off medical debt climbed from 34 percent to 41 percent between 2005 and 2007, bringing the total to 72 million, as per recent survey findings from The Commonwealth Fund. In addition, 7 million adults age 65 and over also had problems paying medical bills, for a total of 79 million adults with medical bill problems or medical debt........

| How memory deals with a change in plans
 You're about to leave work at the end of the day when your cell phone rings: it's your spouse, asking that you pick up a gallon of milk on the way home. Before you head out the door, though, your spouse calls again and asks you to stop by the hardware store too. Based on your knowledge of the area and rush-hour traffic, you decide to get the milk first and the toilet plunger second. But whoops! The phone rings again. This time, it's your boss, asking you to work late. That means another change of plans........

| For Earlier Detection Of Autism
 Recently, Harvard scientists reported that children with autism have a wide range of genetic defects, making it nearly impossible to develop a simple genetic test to identify the disorder. Now, University of Missouri scientists are studying 3-D imaging to reveal correlations in the facial features and brain structures of children with autism spectrum disorder (ASD), which will enable them to develop a formula for earlier detection of the disorder. The scientists anticipate their work also will reveal genetic clues that can direct additional research. Autism is a brain disorder characterized by a complex of social, communication and behavioral difficulties........

| Oral contraceptives may ease suffering of women with severe PMS
 A new clinical trial at the University of North Carolina at Chapel Hill using a popular low-dose contraceptive could uncover a more effective therapy for the 5 to 10 percent of women who suffer from premenstrual dysphoric disorder (PMDD). PMDD is much more severe than premenstrual syndrome, or PMS. The disorder interferes with a woman's ability to function effectively several days out of each month, every month. Physical symptoms include bloating, low energy, heart palpitations and joint or muscle pain. Far more disruptive emotional symptoms include irritability, anxiety, depression, mood swings, difficulty focusing and trouble sleeping. For a number of women with PMDD, five or more of these symptoms occur the week before menstruation starts and disappear a few days after the period begins........

| Chemical Liberated by Leaky Gut
 In up to 20 percent of people infected with HIV, the virus manages to escape from the bloodstream and cross into the brain, resulting in HIV-associated dementia and other cognitive disorders. Now, researchers at the Albert Einstein College of Medicine of Yeshiva University have found good evidence that a component of the cell walls of intestinal bacteria - a chemical present in high levels in the blood of HIV-infected people - helps HIV to penetrate the usually-impregnable blood brain barrier (BBB). The findings, reported in the recent issue of the Journal of Virology, could lead to strategies for preventing HIV from entering the brain and causing serious complications........

| In the long run, exertion regulation wins
 Long-distance running is widely seen as one of the great physical challenges a human can undertake and as the 2008 Summer Olympics commence in Beijing on August 8, a number of eager sports fans will await with baited breath the last event of the Games the men's marathon, held on August 24. For these armchair fans, how marathon runners can complete the gruelling, 42.195 km event physically and mentally may seem like a great mystery........

 Poor physical control and coordination in childhood are associated with an increased risk of obesity in later life, suggests a study published on BMJ.com today. The research contributes to a growing body of evidence on the link between poorer cognitive function in childhood and obesity and type 2 diabetes in adults........

| Targeted radiation therapy can control limited cancer spread
 Precisely targeted radiation treatment can eradicate all evidence of disease in selected patients with cancer that has spread to only a few sites, suggests the first published report from an ongoing clinical trial. In the August 15, 2008, issue of Clinical Cancer Research, (published online August 12) scientists from the University of Chicago Medical Center report that targeted radiation treatment had completely controlled all signs of cancer in 21 percent of patients who had five or fewer sites of metastatic disease........

| 'Erasing' drug-associated memories
 'Erasing' drug-associated memories may prevent recovering drug abusers from relapsing, scientists at the University of Cambridge have discovered. The team, led by Professor Barry Everitt, was able to reduce drug-seeking behaviours in rats by blocking a brain chemical receptor important to learning and memory during the recall of drug-associated memories. Their research, which was funded by the Medical Research Council, was published in the 13 recent issue of The Journal of Neuroscience........
