Vascular complications of fungal meningitis after contaminated spinal injections

2013-07-23
(Press-News.org) A case series by researchers at Vanderbilt University, Nashville, Tenn., examined three patients with ischemic stroke who later received a diagnosis of fungal meningitis attributed to epidural injections of contaminated methylprednisolone for low back pain.

The recent identification of injections of contaminated methylprednisolone acetate has highlighted the different clinical presentations of fungal meningitis, which can have an incubation period of one to four weeks between the last spinal injection and when a patient seeks medical care.

"Fungal meningitis due to injections of contaminated methylprednisolone acetate can present with vascular sequelae in immunocompetent individuals. This is particularly germane to neurologists because better recognition of clinical characteristics of patients with fungal meningitis and ischemic stroke will provide more timely and efficient care," the paper concludes. ### (JAMA Neurol.

Chips that mimic the brain

2013-07-23
No computer works as efficiently as the human brain – so much so that building an artificial brain is the goal of many scientists. Neuroinformatics researchers from the University of Zurich and ETH Zurich have now made a breakthrough in this direction by understanding how to configure so-called neuromorphic chips to imitate the brain's information processing abilities in real-time. They demonstrated this by building an artificial sensory processing system that exhibits cognitive abilities. New approach: simulating biological neurons Most approaches in neuroinformatics ...

Scientists identify key to learning new words

2013-07-23
For the first time scientists have identified how a pathway in the brain which is unique to humans allows us to learn new words. The average adult's vocabulary consists of about 30,000 words. This ability seems unique to humans as even the species closest to us -- chimps -- manage to learn no more than 100. It has long been believed that language learning depends on the integration of hearing and repeating words but the neural mechanisms behind learning new words remained unclear. Previous studies have shown that this may be related to a pathway in the brain only ...

Learning a language depends on good connection between regions of the left hemisphere of the brain

2013-07-23
Language is a uniquely human ability. The average person's vocabulary consists of about thirty thousand words, although there are individual differences in the ability to learn a new language. It has long been believed that language acquisition depends on the integration of the information between motor and auditory representation of words in the brain, but the neural mechanisms that lie behind learning new words remained unclear. Now, a study made by researchers from the group of Cognition and Brain Plasticity at the Bellvitge Biomedical Research Institute (IDIBELL) ...

BMC surgeon recommends off-pump coronary artery bypass grafting be abandoned

2013-07-23
(Boston) - In a Special Report in the current issue of Circulation, Boston Medical Center cardiothoracic surgeon Harold Lazar, MD, has found that off-pump coronary artery bypass graft (OPCAB) surgery has failed to show any significant improvement in short-term morbidity or mortality as compared to the traditional on-pump coronary artery bypass graft (CABG) surgery. He recommends that the technique be abandoned, unless surgeons who perform off-pump surgery can show that their own results are as good as results reported with the traditional on-pump surgery. During off-pump ...

Geochemical 'fingerprints' leave evidence that megafloods eroded steep gorge

2013-07-23
The Yarlung-Tsangpo River in southern Asia drops rapidly through the Himalaya Mountains on its way to the Bay of Bengal, losing about 7,000 feet of elevation through the precipitously steep Tsangpo Gorge. For the first time, scientists have direct geochemical evidence that the 150-mile long gorge, possibly the world's deepest, was the conduit by which megafloods from glacial lakes, perhaps half the volume of Lake Erie, drained suddenly and catastrophically through the Himalayas when their ice dams failed at times during the last 2 million years. "You would expect that ...

Off-grid sterilization with Rice U.'s 'solar steam'

2013-07-23
HOUSTON – (July 22, 2013) – Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The "solar steam" sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat. The technology is described online in a July 8 paper in the Proceedings of the National Academy of Sciences Early Edition. In the paper, researchers from Rice's Laboratory for Nanophotonics (LANP) show two ways that solar steam ...

Fires in Eastern Russian and Siberia

2013-07-23
Forest fires are burning north and east of Russia's Irkutsk Oblast. The Irkutsk Oblast is located in southeastern Siberia in the basins of Angara, Lena, and Nizhnyaya Tunguska Rivers. NASA's Aqua satellite passed over the area and captured an image showing multiple forest fires and smoke plumes. Some of the places affected by the smoke include Cokhchuolu, Ust'ye-Chony, Skysykatakh, and Chernyshevskiy along the Vilyuy River. These appear to be recreational areas. South of the Vilyuy River is the town of Mirny. It is known for having the world's largest diamond mine. ...

Fires in Idaho

2013-07-23
Forest fires continue to plague the hot, dry western part of the United States this summer. In Idaho, several fires were spotted by NASA's Aqua satellite on July 20, 2013. Actively burning areas, detected by MODIS's thermal bands, are outlined in red. The Lodgepole Fire was detected at noon on Saturday, July 20. Local fire resources were dispatched to the scene where aggressive fire suppression efforts were put into place. The fire is currently burning in lodge pole pine and dispersed Douglas fir. Currently 650 acres have burned and the cause of this fire is under investigation. The ...

Land-clearing Blazes in Indonesia

2013-07-23
In Indonesia, land-clearing blazes dot the countryside. Fires for clearing land have been outlowed for all but the smallest landowners, but the "slash-and-burn" practice still persists despite cloaking Southeast Asia in toxic pollution for weeks. Better and more available satellite technology is helping identify culprits behind land-clearing blazes in Indonesia. Unprecedented levels of air pollution in Singapore and Malaysia in June led to respiratory illnesses, school closings, and grounded aircraft. This year it was so bad that in some affected areas there was a 100 ...

Physician bonuses help drive increases in surgery with minimal patient benefit: McMaster study

2013-07-23
Hamilton, ON (July 22, 2013) – Financial incentives for Ontario surgeons are likely a key factor driving greater use of laparoscopic colon cancer surgery, says a study led by a McMaster University surgeon. The research, published online by the Annals of Surgical Oncology, found that between 2002 and 2009 there was an increase in laparoscopic versus traditional open techniques for colon and rectal cancer surgery. These increases were associated with only minimal decreases in how long patients stayed in hospital after surgery and no changes in the survival of patients. ...
