Families, doctors, advocates urgently seeking answers in epilepsy deaths
One in 26 Americans will develop epilepsy over the course of a lifetime. In advance of the June 23-26 Partners Against Mortality in Epilepsy Conference, epilepsy experts and people who face seizures are sounding the alarm on a greatly underestimated problem -- epilepsy-related deaths. Although epilepsy affects 3 million Americans, communication and understanding around the risk of mortality remains low, creating a blind spot for caregivers that can prove devastating. (2016-04-29)

Biomarker may be able to help predict risk of heart failure, cardiovascular death
Certain measures of the blood biomarker cardiac troponin T, a cardiac-specific protein, using a highly sensitive test, are associated with the development of heart failure or cardiovascular death in older adults, according to a study that will appear in the Dec. 8 issue of JAMA. The study is being released early online because it will be presented at the American Heart Association's annual meeting. (2010-11-15)

Mayo Clinic researchers confirm value of therapeutic hypothermia after cardiac arrest
Mayo Clinic researchers confirmed that patients who receive therapeutic hypothermia after resuscitation from cardiac arrest have favorable chances of surviving the event and recovering good functional status. In therapeutic hypothermia, a patient's body temperature is cooled to 33 degrees Celsius following resuscitation from cardiac arrest, in order to slow the brain's metabolism and protect the brain against the damage initiated by the lack of blood flow and oxygenation. This study was published in the December 2010 issue of Annals of Neurology. (2011-02-18)

Tailoring mitochondria to the cell's needs
Cells increase their complement of mitochondria in response to rising metabolic demands or altered physiological conditions. This biosynthetic process is complicated, in part because mitochondrial composition varies between cell types. Lehman et al. now show that the transcriptional co-activator PGC-1 is limiting for mitochondrial proliferation in cardiac muscle, and they argue that this factor helps direct quantitative and qualitative changes in the mitochondrial population of various cells. (2000-09-30)

For some, aspirin doesn't increase risk of recurring hemorrhagic stroke
Because aspirin may cause bleeding, it is typically avoided in people who have had a hemorrhagic stroke, also called intracerebral hemorrhage. A new study, however, finds that aspirin may not increase the risk of recurrent intracerebral hemorrhage. The study is published in the January 24, 2006 issue of Neurology, the scientific journal of the American Academy of Neurology. (2006-01-23)

Higher death rate for heart attack patients with additional non-cardiac conditions
Heart attack patients who also have another acute condition such as stroke, kidney failure and pneumonia may have a poorer outcome than those without these conditions, and those with the most severe conditions account for a disproportionate percentage of hospital deaths, researchers at Yale School of Medicine report in a recent American Journal of Medicine. (2006-11-10)

CPR is successful without mouth-to-mouth, but not without oxygen
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. Scientists tested different scenarios in an animal study of cardiac arrest. Rats received either 100 percent oxygen, 21 percent oxygen -- the equivalent of room air -- or no oxygen (100 percent nitrogen) at the same time they received cardiopulmonary resuscitation (CPR). (2009-11-30)
