Use of hypothermia does not improve outcomes for adults with severe meningitis; may be harmful
2013-10-08
(Press-News.org) Bruno Mourvillier, M.D., of the Université Paris Diderot, Sorbonne Paris Cité, Paris, and colleagues conducted a study to examine whether treatment with hypothermia would improve the functional outcome of comatose patients with bacterial meningitis compared with standard care.
Among adults with bacterial meningitis, the death rate and frequency of neurologic complications are high, indicating the need for new therapeutic approaches. Clinical trials of patients with trauma who were treated with hypothermia have shown a decrease of intracranial pressure, suggesting a potential benefit of this technique in bacterial meningitis, according to background information in the article.
The randomized trial conducted in 49 intensive care units in France between February 2009 and November 2011 assessed 130 patients for eligibility and randomized 98 comatose adults with community acquired bacterial meningitis to the hypothermia group, where patients received a loading dose of 39°F cold saline and were cooled to 90°F to 93°F for 48 hours, or standard care.
The trial was stopped early because of concerns over excess mortality in the hypothermia group (25 of 49 patients [51 percent]) compared with the control group (15 of 49 patients [31 percent]). At 3 months, 86 percent in the hypothermia group compared with 74 percent in the control group had an unfavorable outcome (as gauged via the Glasgow Outcome Scale [a functional assessment inventory]).
"In conclusion, our trial does not support the use of hypothermia in adults with severe meningitis. Moderate hypothermia did not improve outcome in patients with severe bacterial meningitis and may even be harmful. Our results may have important implications for future trials on hypothermia in patients presenting with septic shock or stroke. Careful evaluation of safety issues in these future and ongoing trials are needed," the authors write.

PULLMAN, Wash.—Using Montana's fast-growing Flathead County as a template, a Washington State University researcher has found that moderately restrictive land-use policies can significantly curb the potential damage of rural wildfires. However, highly restrictive planning laws will not do much more.
"Effective land-use planning can reduce wildfire risk," says Travis Paveglio, a clinical assistant professor in the Edward R. Murrow College of Communication whose research focuses on wildfire, environmental hazards and natural resource management. "However, it's one of a suite ...

Bacterial cells use an impressive range of strategies to grow, develop and sustain themselves. Despite their tiny size, these specialized machines interact with one another in intricate ways.
In new research conducted at Arizona State University's Biodesign Institute, Jonathan Badalamenti, César Torres and Rosa Krajmalnik-Brown explore the relationships of two important bacterial forms, demonstrating their ability to produce electricity by coordinating their metabolic activities.
In a pair of papers recently appearing in the journal Biotechnology and Bioengineering, ...

UNIVERSITY OF CALIFORNIA, BERKELEY'S HAAS SCHOOL OF BUSINESS – Most know that hiding something from others can cause internal angst. New research suggests the consequences can go far beyond emotional strife and that being forced to keep information concealed, such as one's sexual orientation, disrupts the concealer's basic skills and abilities, including intellectual acuity, physical strength, and interpersonal grace—skills critical to workplace success.

Next time your kids complain about putting on sunscreen, tell them this: Sunscreen shields a superhero gene that protects them from getting cancer.
It is widely accepted that sunscreen stops you from getting burnt but to date there has been academic debate about the effectiveness of sunscreen in preventing skin cancers.
Now QUT has undertaken a world-first human study to assess the impact of sunscreen at the molecular level.
Researchers found sunscreen provides 100 per cent protection against all three forms of skin cancer: BCC (basal cell carcinoma); SCC (squamous ...

According to a Finnish study, women with eating disorders are less likely to have children than others in their age group. The discrepancy is the most apparent in anorexia sufferers. In this group, the number of pregnancies was less than half of that of the control group.
The likelihood of abortion was more than double for bulimics than for others in the same age group. Meanwhile, the likelihood for miscarriage was more than triple for binge-eating disorder (BED) sufferers. For women who had been in treatment for BED, nearly half of their pregnancies ended in miscarriage.
"Early ...

Many chemicals we use in everyday life are derived from fossil resources. Due to the increasing concerns on the use of fossil resources, there has been much interest in producing chemicals from renewable resources through biotechnology.
Phenol is an important commodity chemical, and is a starting material for the production of numerous industrial chemicals and polymers, including bisphenol A and phenolic resins, and others. At present, the production of phenol entirely depends on the chemical synthesis from benzene, and its annual production exceeds 8 million tons worldwide. ...

Professor Martin Richards, of the Archaeogenetics Research Group at the University of Huddersfield, has published a paper uncovering new information about how Ashkenazi Jewish men moved into Europe from the Middle East, and their marriage practices with European women.
The origins of Ashkenazi Jews – that is, Jews with recent ancestry in central and Eastern Europe – is a long-standing controversy. It is usually assumed that their ancestors migrated into Europe from Palestine in the first century AD, after the destruction of the Second Temple by the Romans, with some intermarriage ...

Graphene has extreme conductivity and is completely transparent while being inexpensive and nontoxic. This makes it a perfect candidate material for transparent contact layers for use in solar cells to conduct electricity without reducing the amount of incoming light - at least in theory. Whether or not this holds true in a real world setting is questionable as there is no such thing as "ideal" graphene - a free floating, flat honeycomb structure consisting of a single layer of carbon atoms: interactions with adjacent layers can change graphene's properties dramatically. ...

The first ever evidence of a comet entering Earth's atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered by a team of South African scientists and international collaborators.
The discovery has not only provided the first definitive proof of a comet striking Earth, millions of years ago, but it could also help us to unlock, in the future, the secrets of the formation of our solar system.
"Comets always visit our skies – they're these dirty snowballs of ice mixed with dust – but never before in ...
