CDC: Man died of rabies from kidney transplant - CNN.com - 0 views

www.cnn.com/...index.html rabies virus transplant
shared by Nate Scheibe on 15 Mar 13 - No Cached
  • Doctors knew the donor had encephalitis, an inflammation of the brain, when they harvested the organs. However, they didn't know rabies was the cause.
  • In this most recent case, the donor was experiencing "changes in mental status" before he died, according to Dr. Matthew Kuehnert, director of the CDC's Office of Blood, Organ, and Other Tissue Safety. He said doctors in Florida tested the donor for various causes of encephalitis, including West Nile Virus and herpes, but did not test for rabies.
  • Hospitals do test for other causes of encephalitis, and if no cause is found, the organs are donated.
  • Nate Scheibe on 15 Mar 13
     
    The part that is most concerning is that the doctors knew the patient had encephalitis (granted not all causes of encephalitis are infectious in nature) and decided to donate the organs anyway.

shared by Katelyn Madigan on 13 Mar 13 - No Cached
  • Karenia brevis algae, which cause red tide blooms across the Gulf of Mexico, become two to seven times more toxic when levels of phosphorus, a major algal nutrient found in fertilizers and human waste, are low.
  • excess nutrients like phosphorus and nitrogen play key roles in fueling algal growth and harmful algal bloom development.

      This is pretty much exactly what we covered in lecture. I just wonder how far/severe the outcome will be until harsh regulation takes place?
  • Overuse and improper use of antibiotics over the years, both in the medical community and the livestock industry, has led to an increase in the number of bacteria that are drug-resistant.
  • At least 80 percent of antibiotics used annually in the U.S. are used routinely in livestock to promote growth.

  • Food and Drug Administration
  • banned only one type of antibiotic in livestock and urged the industry to voluntarily limit antibiotic use to promote growth.

    While the number of confirmed cases is really low, the unnerving aspect is that 8 of the 14 people infected died.

  • “We have a very serious problem, and we need to sound an alarm.”
  • Healthcare institutions in 42 states have now identified at least one case of CRE. The occurrence of this resistance in the overall family of bacteria has risen at least four-fold over 10 years. In the CDC’s surveillance networks, 4.6 percent of hospitals and 17.8 percent of long-term care facilities diagnosed this bug in the first half of 2012.
  • CRE stands for “carbapenem-resistant Enterobacteriaceae.” Enterobacteriaceae are a family of more than 70 bacteria which share the characteristic of being gut-dwelling (“entero”)
  • ...3 more annotations...
  • the CDC reviewed six steps that they first published last year in a CRE Toolkit and want health care facilities to take:
  • But an important point is that none of this is required, and none of this is funded.
  • There are no reimbursements, under Medicare, for infection-control as a hospital task

    This article does a good job summarizing this week's announcement by the CDC director on the gravity of the CRE problem.

  • Doctors in the US have made medical history by effectively curing a child born with HIV, the first time such a case has been documented.
  • Dr Hannah Gay, who cared for the child at the University of Mississippi medical centre, told the Guardian the case amounted to the first "functional cure" of an HIV-infected child.
  • but it is likely that a tiny amount remains in their body.

  • ypically, women with HIV are given antiretroviral drugs during pregnancy to minimise the amount of virus in their blood. Their newborns go on courses of drugs too, to reduce their risk of infection further. The strategy can stop around 98% of HIV transmission from mother to child.

    Exciting when AIDS research takes a step forward. However, is it true that although they cannot detect the virus, it may lie dormant? How sensitive are those tests? There was a case of a man who had HIV and leukemia and so they treated him with a bone marrow transplant from someone who was resistant to HIV. The man was said to be cured but there were later debates on the validity.

Viruses Can Have Immune System, Study Finds | Biology | Sci-News.com - 1 views

shared by Richard Herron on 03 Mar 13 - No Cached
  • A new research led by Dr Kimberley Seed from the Tufts University School of Medicine provides the first evidence that bacteriophages – viruses that infect and replicate within bacteria – can acquire a wholly functional and adaptive immune system.
  • The study, published today in the journal Nature, finds that a viral predator of the cholera bacteria can steal the functional immune system of bacteria and use it against its bacterial host.
  • Developing phage therapy is particularly important because some bacteria, called superbugs, are resistant to most or all current antibiotics.
  • ...2 more annotations...
  • This study focused on a phage that attacks Vibrio cholerae, the bacterium responsible for cholera epidemics in humans.
  • Finding a CRISPR/Cas system in a phage shows that there is gene flow between the phage and bacteria even for something as large and complex as the genes for an adaptive immune system,”
