Recently these large multiprotein transport channels have also been shown to play an essential role in developmental gene regulation. Despite the critical role in nuclear function, however, nuclear pore complexes remain somewhat shadowy figures, with many details about their formation shrouded in mystery. http://phys.org/news195392585.html Biology Thu, 10 Jun 2010 13:00:02 EST news195392585 The odds of surviving cardiac arrest may depend on which part of town you call home and whether anyone in the neighborhood comes to your rescue by attempting to perform cardiopulmonary resuscitation (CPR), according to a first-of-its-kind study in the June issue of the Annals of Internal Medicine. http://phys.org/news194506591.html Medicine & Health Mon, 31 May 2010 17:00:01 EST news194506591 (PhysOrg.com) -- Results from clinical trials performed in Europe and New Zealand, published online in the New England Journal of Medicine, demonstrate the effectiveness of a new less-invasive, subcutaneous implantable cardioverter defibrillator (ICD) for sudden cardiac arrest, a potentially fatal electrical malfunction of the heart. http://phys.org/news193503290.html Medicine & Health Wed, 19 May 2010 15:55:02 EST news193503290 Treatment decisions involving patients with severe brain injury vary widely between medical institutions and appear to be more driven by hospital and physician practices and priorities. In an article appearing today in the New England Journal of Medicine, physicians at the University of Rochester Medical Center (URMC) argue that providers must take steps to develop a process of communication and decision-making that gives greater weight and voice to the informed preferences of patients and their families. http://phys.org/news192908864.html Medicine & Health Wed, 12 May 2010 19:00:01 EST news192908864 Researchers have discovered a new disorder linked to heart problems that stems from a genetic defect in the protein glycogenin. In a worst case scenario, disruption of this protein's function can lead to cardiac arrest, which is exactly what happened to the young man whose case triggered the investigation at Sahlgrenska University Hospital at the University of Gothenburg, Sweden, that led to a brand new diagnosis. http://phys.org/news190895346.html Medicine & Health Mon, 19 Apr 2010 12:10:01 EST news190895346 Physician-scientists at the Cedars-Sinai Heart Institute have found that a genetic variation is associated with lower risk of sudden cardiac arrest, a disorder that gives little warning and is fatal in about 95 percent of cases. Findings will be published tomorrow by the Public Library of Science (PloS One). http://phys.org/news188737525.html Medicine & Health Thu, 25 Mar 2010 12:40:01 EST news188737525 Sudden Cardiac Arrest syndrome (SCA) is poorly understood, but it's a real danger for the otherwise young and healthy. For no apparent reason, the heart suddenly stops beating, and without treatment death may follow within minutes. It's why some athletes drop dead on the track and why a young man, without any warning, suddenly dies while sitting at his desk. SCA accounts for approximately 300,000 deaths per year in the U.S. http://phys.org/news187529969.html Medicine & Health Thu, 11 Mar 2010 11:40:01 EST news187529969 (PhysOrg.com) -- Hospital care providers need to be more aware that cardiac arrest from a medication-induced heart rhythm problem is a rare but potentially catastrophic event in patients, according to a joint scientific statement from the American Heart Association and American College of Cardiology. http://phys.org/news184872372.html Medicine & Health Mon, 08 Feb 2010 18:30:05 EST news184872372 People who are in car crashes or suffer serious falls, gunshot or knife wounds and other injuries at nights or on weekends do not appear to be affected by the same medical care disparities as patients who suffer heart attacks, strokes, cardiac arrests and other time-sensitive illnesses during those "off hours," according to new research from the University of Pennsylvania School of Medicine. In contrast to previous, multi-hospital studies showing that patients treated for cardiac or neurological emergencies overnight and on weekends are more likely to experience complications and even die than those who come to the hospital on weekdays, the new pilot findings suggest that trauma patients are insulated from this so-called "weekend effect" tied to the time of day in which they're brought to the hospital. http://phys.org/news183437637.html Medicine & Health Sat, 23 Jan 2010 03:40:01 EST news183437637 Dispatchers should assertively give cardiopulmonary resuscitation (CPR) instructions to bystanders who suspect someone is in cardiac arrest because the benefits from correctly recommending CPR for someone who needs it greatly outweigh the risks from recommending CPR for someone who does not, researchers said in Circulation: Journal of the American Heart Association. http://phys.org/news180708680.html Medicine & Health Tue, 22 Dec 2009 13:30:01 EST news180708680 When the heart is stopped and restarted, the patient's life may be saved but their brain is often permanently damaged. Therapeutic hypothermia, a treatment in which the patient's body temperature is lowered and maintained several degrees below normal for a period of time, has been shown to mitigate these harmful effects and improve survival in adults. http://phys.org/news179066375.html Medicine & Health Thu, 03 Dec 2009 12:41:44 EST news179066375 The chance of surviving an out-of-hospital cardiac arrest has not improved since the 1950s, according to a report by the University of Michigan Health System. http://phys.org/news178996473.html Medicine & Health Wed, 02 Dec 2009 17:15:03 EST news178996473 People can survive cardiac arrest if they receive only chest compressions during attempts to revive them - as advised by the current American Heart Association guidelines. But they cannot survive without access to oxygen sometime during the resuscitation effort, research suggests. http://phys.org/news178812267.html Medicine & Health Mon, 30 Nov 2009 17:40:02 EST news178812267 Patients with an out-of-hospital cardiac arrest who received intravenous (IV) drug administration during treatment, recommended in life support guidelines, had higher rates of short term survival but no statistically significant improvement in survival to hospital discharge or long-term survival, compared to patients who did not receive IV drug administration, according to a study in the November 25 issue of JAMA. http://phys.org/news178311128.html Medicine & Health Tue, 24 Nov 2009 19:10:01 EST news178311128 A woman who suffers sudden cardiac arrest is significantly less likely than a man to exhibit the decrease in the heart's pumping ability that is widely recognized as a precursor, says a new study in the Nov. 24 Journal of the American College of Cardiology. http://phys.org/news177663733.html Medicine & Health Tue, 17 Nov 2009 07:20:01 EST news177663733 Virginia Commonwealth University Medical Center and the Richmond Ambulance Authority have improved resuscitation and survival rates dramatically for cardiac arrest patients by training and equipping paramedics to begin lowering a patient's body temperature in the field during resuscitation and following up at the hospital with a host of high-tech strategies to improve the odds of survival. http://phys.org/news177604279.html Medicine & Health Mon, 16 Nov 2009 15:10:09 EST news177604279 The chance of surviving a cardiac arrest outside a hospital was found to be twice as high when bystanders performed continuous chest compressions without mouth-to-mouth breathing than when bystanders performed standard CPR. These are the latest findings reported by the Resuscitation Research Group at the University of Arizona Sarver Heart Center and the SHARE Program (Save Hearts in Arizona Research and Education) at the Arizona Department of Health Services. http://phys.org/news177599075.html Medicine & Health Mon, 16 Nov 2009 13:30:03 EST news177599075
