NEW ORLEANS -- Over the past few decades, cheerleading has evolved from leading the crowd in cheers at football games to a competitive, year-round sport featuring complex acrobatic stunts performed by a growing number of athletes – and as a result the number and severity of injuries from cheerleading has also surged. In a new policy statement, the American Academy of Pediatrics (AAP) urges coaches, parents and school officials to follow injury-prevention guidelines, develop emergency plans and ensure cheerleading programs have access to the same level of qualified coaches, ...

A new inhibitor helps previously nicotine-addicted rats stay on the wagon, according to a study published on October 22nd in the Journal of Experimental Medicine. Kicking the cigarette habit is difficult enough, but resisting the urge to light up in situations previously associated with smoking can be a quitter's downfall. But help may be at hand. A new inhibitor developed by Fang Liu and colleagues at the Centre for Addiction and Mental Health in Toronto helped ex-smoker rats resist that urge. Liu and colleagues found that long-term nicotine exposure caused two neurotransmitter ...

Mothers and newborns who are both admitted to an intensive care unit (ICU) after delivery are significantly more likely to die compared with mom–baby pairs not needing ICU admission, found a study in CMAJ (Canadian Medical Association Journal). As well, when both mother and baby require admission to an ICU, they are much more likely to be managed at different hospitals, thereby negatively impacting maternal–infant bonding. Researchers completed a population-based study of all 1.02 million live born singleton deliveries in Ontario between 2002 and 2010. They found that ...

Engaging in a combination of healthy behaviours, such as not smoking, moderate alcohol consumption, exercise, and eating fruits and vegetables daily makes it significantly more likely people will stay healthy as they age, according to a study published in CMAJ (Canadian Medical Association Journal). "Our study shows the cumulative impact of healthy behaviours on successful aging — the greater the number of healthy behaviours, the greater the benefit," writes Dr. Séverine Sabia, Department of Epidemiology and Public Health, UCL (University College London), UK, with coauthors. Successful ...

A study in The Journal of Cell Biology identifies a motor protein that ferries HIV to the plasma membrane, helping the virus escape from macrophages. HIV reproduces inside disease-fighting T cells, killing them in the process. But the virus can also replicate in macrophages, which survive infection and serve as reservoirs of HIV. In T cells, new viral particles are formed at the plasma membrane, but in macrophages the viruses assemble inside cytoplasmic containers called virus-containing compartments (VCCs). To break out of a macrophage, a virus particle therefore has ...

Las Vegas, NV (October 22, 2012) – A stay in the hospital may not be the only way to acquire Clostridium difficile diarrhea – but the potentially life-threatening infection may be associated with a number of health complications in hospitalized children, according to the findings from two studies unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas. In a separate case report also presented today, fecal microbiota transplantation in a 20-month old with recurrent Clostridium difficile infection (CDI) suggests the therapeutic ...

Las Vegas, NV (October 22, 2012) –Three separate studies presented today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas help to advance understanding of the differences between African American and Caucasian patients with Inflammatory Bowel Disease (IBD) and provide clinicians with new insight on how racial disparities involving disease characteristics, infliximab use, and fistulizing Crohn's disease may impact their patients—and their decisions on how best to manage the disease. The incidence of inflammatory bowel disease ...

AUDIO: This audio clip captures the unusual speech-like sounds from white whale NOC. See supplemental information for more data. Click here for more information. For the first time, researchers have been able to show by acoustic analysis that whales—or at least one very special white whale—can imitate the voices of humans. That's a surprise, because whales typically produce sounds in a manner that is wholly different from humans, say researchers who report their findings in the ...

Some African dung beetles roll their feasts of dung away to avoid the hordes of other hungry bugs at the pile. But now researchers who report their findings in the October 23 issue of Current Biology, a Cell Press publication, have discovered that the beetles also use the balls in another, rather clever way: The moist balls keep the bugs cool even as they push a weight up to 50 times heavier than their own bodies across the scorching sand. "Like an air conditioning unit, the moist ball is cooled by evaporative cooling," said Jochen Smolka of Lund University. "The beetles ...

(PHILADELPHIA) – Researchers at Thomas Jefferson University Hospital have shown that combining distal protection devices with the prophylactic use of the drug nicardipine is more effective at preventing life-threatening complications following a percutaneous coronary intervention (PCI) (angioplasty, stenting) on patients who have undergone previous bypass surgery than distal protection devices alone. Their findings will be presented on Tuesday, October 23rd, at 8 a.m. at the Transcatheter Cardiovascular Therapeutics (TCT) conference, at the Miami Beach Convention Center ...

Dung beetles roll their feasts of dung away to avoid the hoards of other hungry competitors at the dung pile. But now a team of researchers from South Africa and Sweden have discovered that they also use their balls in another, rather clever way. The moist balls keep the beetles cool even as they push a weight up to 50 times heavier than their own bodies across the hot sand. "The beetles climb on top of their moist balls whenever their front legs and heads overheat," said Prof. Marcus Byrne from Wits University. "We stumbled upon this behaviour by accident while watching ...

Las Vegas, NV (October 22, 2012) – Research unveiled today at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas suggests a possible overlap of symptoms of two prevalent GI disorders: irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) and further suggests a possible link between subtle GI tract inflammation and IBS symptoms—a link that is also the focus of the first systemic review of the literature on this topic and an editorial both published in this month's American Journal of Gastroenterology. One study ...
