New defibrillator signals doctor of patient's irregular heartbeat or device malfunction
Loyola first in U.S. to implant new FDA-approved device In a major advance for heart patients, Loyola University Health System is the first hospital in the U.S. to implant into a patient a new FDA-approved defibrillator which automatically signals the doctor via wireless satellite transmission if the patient's heart beats abnormally or if the device malfunctions, e.g., battery failure.</p...Malfunctioning bone marrow cells sabotage nerve cells in diabetes
Malfunctioning bone marrow cells that produce insulin appear to cause a dangerous nerve condition called neuropathy that disables many people with diabetes, said a research team led by Baylor College of Medicine in Houston. The report from researchers at BCM, Shiga University of Medical Science in Japan, and the University of Chicago appears online today in the Proceedings of the National...How genetic malfunction causes a form of retardation
Researchers have discovered that the genetic malfunction that causes a form of mental retardation called Noonan Syndrome (NS) produces an imbalance in the genesis of two types of cells in the developing embryonic brain. This imbalance, they theorize, could explain how the genetic abnormality gives rise to the neural pathology of the disorder. More broadly, they said, the new insight into the mech...Gene malfunctions cause schizophrenia, depression symptoms in mice
Researchers have demonstrated for the first time that malfunction of a gene that had been associated with schizophrenia and depression does indeed cause symptoms of those disorders. They said their findings in mice offer a possible animal model for developing treatments for schizophrenia and depression. Also, they said their findings support the theory that the two disorders share common genetic...Hyperactivity disorder a biological malfunction
Children with Attention Deficit Hyperactivity Disorder - ADHD - have underactive parts of the brain which deal with decision-making, thinking and planning. The abnormality was revealed by a magnetic scanning device// which enabled researchers to look at the brains of children without harming them from radioactivity. Eric Taylor, Professor of Child Psychiatry at the Medical Research Council, said...Withdrawal Notice Issued For Older Pacemakers Due To Malfunctioning of the Device
Health professionals have been recently notified that some older pacemakers manufactured by Guidant Corporation may malfunction due to a build-up of moisture //in the device. The products include early generation designs that have not been sold or implanted in the past 4 years, some of the names of the affected models include the Pulsar Max, Pulsar, Discovery, Meridian, Pulsar Max II, Discovery I...Scientists Concerned Over Increasing Malfunction Of Heart Devices
Scientists in the US are worried over the increasing malfunction of heart devices, which they say were directly responsible for 61 deaths between 1990 and 2002. The Food and Drug Administration (FDA) released // a study at a meeting with physicians and heart-device manufacturers recently, which found that 4,225 defibrillators had failed between 2000 and 2003. Same number of defibrillator...Small Kidney Malfunctions Can Increase The Risk Of Deaths
For patients in hospitals, a small increase in the malfunction of the kidneys can lead to an increased risk of death, especially for patients suffering from acute kidney injury (AKI). Researchers from University of California // San Francisco had reported these results in the latest issue of the Journal of the American Society of Nephrology. The researchers had analyzed data on 9,210 h...Malfunction Of Key Growth Factor Increases Mortality Rate From Pulmonary Fibrosis In Blacks
The mortality rate from pulmonary fibrosis in African-Americans is almost twice as high as that found in the Caucasians//. For many years now, researchers have been searching for an explanation for this difference. Now physiologist from Belarus says that she has found why this racial difference exists. "Pulmonary fibrosis is a deadly, very complex disease where the lung's air sacs are r...
