Preventing GVHD by protecting gut stem cells

2011-02-01
(Press-News.org) A protein that protects stem cells in the gut relieves a potentially lethal complication of bone marrow transplantation in mice, according to a study published online on January 31 in the Journal of Experimental Medicine (www.jem.org).

Bone marrow transplantation can cure diseases such as leukemia but it can also lead to a potentially fatal complication known as graft-versus-host disease (GVHD). A group led by Takanori Teshima at Kyushu University in Japan found that mice treated with a protein called R-spondin1 developed less severe GVHD after bone marrow transplantation. R-spondin worked by protecting intestinal stem cells, which help to regenerate damaged tissues and thus dampen inflammation.

Whether R-spondin1 is therapeutic for human bone marrow transplant patients remains to be explored.

Safety checklist use yields 10 percent drop in hospital deaths

2011-02-01
A Johns Hopkins-led safety checklist program that virtually eliminated bloodstream infections in hospital intensive-care units throughout Michigan appears to have also reduced deaths by 10 percent, a new study suggests. Although prior research showed a major reduction in central-line related bloodstream infections at hospitals using the checklist, the new study is the first to show its use directly lowered mortality. "We knew that when we applied safety science principles to the delivery of health care, we would dramatically reduce infections in intensive care units, ...

Argentine ant genome sheds light on a successful pest

2011-02-01
Berkeley — A research team led by scientists at the University of California, Berkeley, and San Francisco State University has unlocked the genetic code of the highly invasive Argentine ant, providing clues as to why this species has been so successful. The draft genome of the Argentine ant (Linepithema humile) – the tiny brown insect that homeowners so frequently find marching en masse through their kitchens – is among a trio of ant genomes being published the week of Jan. 31 in the journal Proceedings of the National Academy of Sciences. The other two ant species are ...

Test for blocked neck arteries only necessary for people with stroke risk factors

2011-02-01
Widespread screening or routine ultrasound for blocked neck arteries to determine stroke risk isn't necessary, according to new guidelines from the American Heart Association/American Stroke Association, American College of Cardiology and other groups. Carotid stenting and carotid endarterectomy are reasonable and effective ways to treat blocked neck arteries, though some patients may be a better candidate for one procedure over the other, the guidelines also state. When the carotid arteries on the side of the neck or vertebral arteries alongside the spinal column ...

MIT: Understanding the autistic mind

2011-02-01
CAMBRIDGE, Mass. -- A study from MIT neuroscientists reveals that high-functioning autistic adults appear to have trouble using theory of mind to make moral judgments in certain situations. Specifically, the researchers found that autistic adults were more likely than non-autistic subjects to blame someone for accidentally causing harm to another person. This shows that their judgments rely more on the outcome of the incident than on an understanding of the person's intentions, says Liane Young, an MIT postdoctoral associate and one of the lead authors of the study, which ...

Wilful neglect of any patient should be criminal offense for doctors and nurses

2011-02-01
The wilful neglect of any patient should become a criminal offence for doctors and nurses in England, as it is in France, suggest ethicists in a leading article published online in the Journal of Medical Ethics. Normally, healthcare professionals in England can only face prosecution if a serious error results in the death of a patient, say the authors from the University of Manchester's Centre for Social Ethics and Policy. But under current mental health legislation, nurses, doctors, and managers can be charged with the criminal offence of wilful neglect, which is ...

Head injury can blight survival up to 13 years later

2011-02-01
A head injury can blight the chances of survival up to 13 years after the event, especially among younger adults, finds research published online in the Journal of Neurology Neurosurgery and Psychiatry. Injury severity seems to make little difference over the longer term, the findings show. The research team tracked over 2,000 people, 757 of whom had sustained a head injury that required admission to one of five hospitals in Glasgow between 1995 and 1996. The rest of the group were split between those who had been admitted to hospital for other reasons, but for the ...

Dogs can accurately sniff out early stage bowel cancer

2011-02-01
Dogs can sniff out bowel cancer in breath and stool samples, with a very high degree of accuracy - even in the early stages of the disease - reveals research published online in the journal Gut. The findings prompt the authors to suggest that chemical compounds for specific cancers circulate throughout the body, which opens up the prospect of developing tests to pick up the disease before it has had the chance to spread elsewhere. A specially trained Labrador retriever completed 74 sniff tests, each comprising five breath (100 to 200 ml) or stool samples (50 ml) at ...

Altered cell metabolism has role in brain tumor development

2011-02-01
DURHAM, N.C. – Scientists at Duke Cancer Institute have discovered that genetic mutations found in brain tumors can alter tumor metabolism. This work could help lead to new designs for anti-cancer drugs based on the unique properties of these tumors. "Malignant glioma appears to be at least two large subclasses of diseases – one that involves mutations in the IDH1 and IDH2 genes and one that doesn't," said Hai Yan, M.D., Ph.D., an associate professor in the Duke Department of Pathology who led a collaborative group of researchers to conduct the study. "The IDH mutation ...

NYU neuroscientists find memory storage, reactivation process more complex than previously thought

2011-02-01
The process we use to store memories is more complex than previously thought, New York University neuroscientists have found. Their research, which appears in the journal the Proceedings of the National Academy of Sciences, underscores the challenges in addressing memory-related ailments, such as post-traumatic stress disorder. The researchers looked at memory consolidation and reconsolidation. Memory consolidation is the neurological process we undergo to store memories after an experience. However, memory is dynamic and changes when new experiences bring to mind old ...

Childhood obesity linked to health habits, not heredity: U-M study

2011-02-01
ANN ARBOR, Mich. – Are some children genetically tuned to be overweight, or is lifestyle to blame for childhood obesity? Check-ups of 1,003 Michigan 6th graders in a school-based health program showed children who are obese were more likely to consume school lunch instead of a packed lunch from home and spend two hours a day watching TV or playing a video game. The results were compiled by the University of Michigan Cardiovascular Center and suggests unhealthy habits are feeding the childhood obesity trend. "For the extremely overweight child, genetic screening may ...
