An overview of the biochemical mechanisms that produce acute nerve cell death in the brain. Covers injuries and disorders including stroke, brain and spinal cord trauma, hypoglycemic coma, and prolonged epileptic seizures. All of these lead to high concentrations of calcium in nerve cells which, in turn, causes degradation of cytoplasmic proteins, cleavage of nuclear DNA, and eventually cell death. The Second Edition contains 11 thoroughly updated chapters and 3 additional chapters that did not appear in the previous edition.
A significant medical event is expected in 1992: the first human use of a fully implantable, long-term cardiac assist device. This timely volume reviews the artificial heart program-and in particular, the National Institutes of Health's major investment-raising important questions. The volume includes: Consideration of the artificial heart versus heart transplantation and other approaches to treating end-stage heart disease, keeping in mind the different outcomes and costs of these treatments. A look at human issues, including the number of people who may require the artificial heart, patient quality of life, and other ethical and societal questions. Examination of how this technology's use can be targeted most appropriately. Attention to achieving access to this technology for all those who can benefit from it. The committee also offers three mechanisms to aid in allocating research and development funds.
J. Navratil The performance of operations on the heart and its replacement by a trans planted or artificial heart has been an age old dream of man. Rehn for example in an early attempt, in 1868 performed a closure of a heart wound after a thoracic puncture. At that time noone thought that this attempt was the beginning of cardiac surgery. The dream was partially realized when the replacement of the heart function by the heart-lungmachine became possible. Immediately following the first operations, cardiac surgeons and cardiologists saw with great enthusiasm that this machine could be an important tool for correcting congenital and non congenital heart diseases. However, the heart-lungmachine...
The United States has the highest per capita spending on health care of any industrialized nation. Yet despite the unprecedented levels of spending, harmful medical errors abound, uncoordinated care continues to frustrate patients and providers, and U.S. healthcare costs continue to increase. The growing ranks of the uninsured, an aging population with a higher prevalence of chronic diseases, and many patients with multiple conditions together constitute more complicating factors in the trend to higher costs of care. A variety of strategies are beginning to be employed throughout the health system to address the central issue of value, with the goal of improving the net ratio of benefits obt...
