A substantial number of older persons -- from 2 to 10 percent of the elderly population -- are physically or mentally abused, and mistreated seniors are three times more likely to die within three years than those who are not abused, report two Cornell University gerontologists in this weeks issue of the medical journal The Lancet.
Reviewing more than 50 articles, Karl Pillemer, professor of human development in the College of Human Ecology at Cornell, has collaborated with Dr. Mark S. Lachs, co-chief of the Division of Geriatrics and Gerontology at the Weill Cornell Medical College in New York City, on a detailed review in The Lancet (Vol. 364, Oct. 2: pp. 1192-1263) on the risk factors, screening, clinical manifestations, diagnosis and treatment of elder abuse.
"This vastly unrecognized and undertreated problem compromises the quality of life for millions of older people worldwide," says Pillemer. "A busy physician, who might see 20 to 40 elderly patients a day, might encounter a case of possible elder abuse every day, but because of a lack of time, resources and a general lack of recognition of the problem, many cases go undetected and untreated, putting our elderly at heightened risk of physical and mental harm, and even death."

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
