New study shows sepsis and pneumonia caused by hospital-acquired infections kill 48,000... - 1 views

  • This is the largest nationally representative study to date of the toll taken by sepsis and pneumonia, two conditions often caused by deadly microbes, including the antibiotic-resistant bacteria MRSA. Such infections can lead to longer hospital stays, serious complications and even death. "In many cases, these conditions could have been avoided with better infection control in hospitals," said Ramanan Laxminarayan, Ph.D., principal investigator for Extending the Cure, a project examining antibiotic resistance based at the Washington, D.C. think-tank Resources for the Future. "Infections that are acquired during the course of a hospital stay cost the United States a staggering amount in terms of lives lost and health care costs," he said. "Hospitals and other health care providers must act now to protect patients from this growing menace." Laxminarayan and his colleagues analyzed 69 million discharge records from hospitals in 40 states and identified two conditions caused by health care-associated infections: sepsis, a potentially lethal systemic response to infection and pneumonia, an infection of the lungs and respiratory tract. The researchers looked at infections that developed after hospitalization. They zeroed in on infections that are often preventable, like a serious bloodstream infection that occurs because of a lapse in sterile technique during surgery, and discovered that the cost of such infections can be quite high: For example, people who developed sepsis after surgery stayed in the hospital 11 days longer and the infections cost an extra $33,000 to treat per person. Even worse, the team found that nearly 20 percent of people who developed sepsis after surgery died as a result of the infection. "That's the tragedy of such cases," said Anup Malani, a study co-author, investigator at Extending the Cure, and professor at the University of Chicago. "In some cases, relatively healthy people check into the hospital for routine surgery. They develop sepsis because of a lapse in infection control—and they can die." The team also looked at pneumonia, an infection that can set in if a disease-causing microbe gets into the lungs—in some cases when a dirty ventilator tube is used. They found that people who developed pneumonia after surgery, which is also thought to be preventable, stayed in the hospital an extra 14 days. Such cases cost an extra $46,000 per person to treat. In 11 percent of the cases, the patient died as a result of the pneumonia infection.

    Two common conditions caused by hospital-acquired infections (HAIs) killed 48,000 people and ramped up health care costs by $8.1 billion in 2006 alone, according to a study released today in the Archives of Internal Medicine.

One Per Cent: Social network lets people with same gut flora hook up - 0 views

  •  
    "The project was kick-started by a huge public response to the team's research into the genetics of gut bacteria. In a previous study the researchers found that certain gut-specific genetic markers were related to obesity and other diseases. "I got between 50 and 100 e-mails from regular people having problems with the stomach or diarrhoea and wondering if we can help them," Peer Bork, a biochemist and co-creator of MyMicrobes, told Nature. This new website will build on that work, whilst also providing support for concerned members of the public."

Strong AI: Safety and Ethical Considerations - 0 views

  •  
    I've been reading up on some of the considerations that must be part and parcel with the actual process of developing strong AI (defined as artificial intelligence that equals or exceeds human-level intelligence), and it seems clear that some pretty important questions must be asked and answered as part of the process.

Price placed on limiting global warming - earth - 0 views

  • Stabilising greenhouse gases at a level that would limit global warming to between 2°C and 4°C will cost between 0.2% and 3.0% of annual GDP, says the latest UN report on climate change. That is up to $1830 billion
  • Such a treaty would succeed the Kyoto Protocol, which ends in 2012.
  • China is projected to become the world's top emitter before 2010 according to the International Energy Agency. However, it and other developing countries argue that policies to battle climate change should not come in the way of their efforts to develop their economies

  • let’s say that one movable synapse could store one byte (8 bits) of memory. That thimble would then contain 1,000 gigabytes (1 terabyte) of information. A thousand thimblefuls make up a whole brain, giving us a million gigabytes — a petabyte — of information. To put this in perspective, the entire archived contents of the Internet fill just three petabytes.

Acupuncture lessens depression symptoms during pregnancy, study shows - 0 views

  • The study authors, led by Rachel Manber, PhD, professor of psychiatry and behavioral sciences, said they hope the results will raise awareness of the problem of depression during pregnancy and provide patients and physicians an alternative to antidepressants. "This standardized acupuncture protocol could be a viable treatment option for depression during pregnancy," they wrote in a paper that will appear in the March issue of Obstetrics & Gynecology. Up to 14 percent of pregnant women may have major depressive disorder, a condition characterized by feelings of dread, gloom and hopelessness, and a loss of interest in normally pleasurable activities. Some women suffer from depression before becoming pregnant, stop taking their medication and then experience a relapse; in other women, pregnancy itself may cause depression.
  • For this study, the researchers recruited 150 women whose pregnancies were between 12 and 30 weeks gestation and who met the criteria for major depressive disorder. The women were randomized to receive one of three treatments: acupuncture specific for depression; control acupuncture, during which needles were inserted in points not known to help alleviate depressive symptoms; or massage. All of the women received eight weeks of therapy and were assessed for depression at the four- and eight-week marks by an interviewer who was unaware of the treatment each woman received. The researchers found that women who received the depression-specific acupuncture experienced a bigger reduction in depression symptoms than the women in the other groups. The response rate — defined as having a 50 percent or greater reduction in symptoms — was 63 percent for the women receiving depression-specific acupuncture, compared with 44 percent for the women in the other two treatment groups combined. The researchers weren't surprised by what they found — a pilot study yielded similar results, and other studies have shown acupuncture is an effective treatment for depression in the general public — but they were pleased with the results. "I don't think that one-size-fits-all treatments are appropriate for everyone, but acupuncture should be considered as an option," said Lyell. "I hope that people will respect the rigorous methodology used in this blinded, randomized, controlled trial and accept the result: Traditional acupuncture was associated with a significant improvement in depression."

    Acupuncture appears to be an effective way to reduce depression symptoms during pregnancy, according to a first-of-its-kind study from Stanford University School of Medicine researchers.
