Advance directives: Implementation leaves much to be desired

2012-10-01
(Press-News.org) Advance directives are not widespread among the elderly. This was revealed by a cross-sectional study of 11 German nursing homes performed by Sarah Sommer and her colleagues and presented in the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2012; 109(37): 577). In the year 2007, only 11% of the nursing home residents had a personally signed advance directive, while a further 1.4% had a proxy directive, i.e., a document signed not by the resident but by a representative. Few of the advance directives made any provision for an acute health crisis. Therefore, many directives are of little help in deciding what treatment to give in such circumstances. Agreements of the nursing staff, who ought to be aware of the directives and their contents, also left much to be desired. For 14 of 23 residents, for example, there had been no discussion of whether they should be resuscitated. The authors surmise that the Advance Directives Act of 2009 will not bring about any substantial or lasting improvement in this state of affairs, because it neither provides incentives nor foresees resources for active guidance. ### http://www.aerzteblatt.de/pdf.asp?id=129878 Contact: jids@med.uni-duesseldorf.de

Trapping weevils and saving monarchs

2012-10-01
This press release is available in Spanish.Ensuring the monarch butterfly's survival by saving its milkweed habitat could result from U.S. Department of Agriculture (USDA) studies initially intended to improve detection of boll weevils with pheromone traps. Charles Suh and his colleagues at the Agricultural Research Service (ARS) Areawide Pest Management Research Unit in College Station, Texas, have found a pheromone formula that is attractive to a major milkweed pest, the milkweed stem weevil. The discovery stems from research originally designed to help improve ...

Macrophage accumulation of triglycerides yields insights into atherosclerosis

2012-10-01
Bethesda, MD—A research report appearing in the Journal of Leukocyte Biology helps explain how specific immune cells, called macrophages, accumulate triglycerides to support their function. Because a characteristic finding in atherosclerosis is the accumulation of fat in macrophages in the arterial wall, understanding how macrophages accumulate triglycerides may lead to new approaches toward slowing or stopping the development of atherosclerosis. "Activation of macrophages leads to the accumulation of triglycerides in macrophages by multiple pathways that may have beneficial ...

Genetic activity in the entire genome of multicellular fungi analysed at a stroke

2012-10-01
With a combination of microscopic laser scissors and modern sequencing methods, biologists at the Ruhr-Universität have analyzed the activity of genes in the entire genome of certain fungi in one fell swoop. Especially with organisms in the millimetre size range, it is a particular challenge because little cell material is available. The scientists of the RUB Department of General and Molecular Botany took advantage of the method to investigate the development of small multicellular fungi. The results are reported in the journal BMC Genomics. Gene activity differs from ...

How sexual power can be disempowering

2012-10-01
Gender roles and norms play a key role in sexual behavior between men and women. It is often assumed that men should dominate women sexually. This assumption may lead to loss of both power and the ability to control sexual behavior among women and men, as well as lead to increased sexual risk-taking, such as not using a female condom. The new study, by Dr. Lisa Rosenthal from Yale University in the US, and her colleagues, is published online in Springer's journal Sex Roles. Social dominance orientation is a measure of people's level of support for social power inequalities ...

Study questions association between common heartburn drugs and risk of pneumonia

2012-10-01
Previous studies that have associated the use of proton pump inhibitors (PPI) – which include popular anti-heartburn medications like Prilosec and Nexium – with an increased incidence of pneumonia may not have found a true cause-and-effect relationship. A study that has been released online by the Journal of General Internal Medicine outlines a strategy for determining when the results of such observational studies may have been distorted by unmeasured factors and then finds that may be the case with the association between PPIs and pneumonia risk. "Our study is the ...

PET predicts early response to treatment for head and neck cancer patients

2012-10-01
Reston, Va. (October 1, 2012) – Determining the optimal treatment course and predicting outcomes may get easier in the future for patients with head and neck sqaumous cell carcinomas (HNSCCs) with the use of an investigational imaging agent. Research published in the October issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET) imaging with 3'-deoxy-3'F-18-fluorothymidine (18-F-FLT) during treatment and early follow-up has the potential to predict therapeutic responses and identify patients needing close follow-up to detect persistent or ...

Radiology is front and center in health care reform

Radiology is front and center in health care reform
2012-10-01
AUGUSTA, Ga. – While it's leveling off, a decade of increased use of sophisticated, expensive, imaging studies has put radiologists and their specialty front and center in health care reform, says the chair of an academic radiology department. That seemingly dubious distinction gives radiologists the chance to take a leadership role in reducing costs, optimizing utilization and improving patient care, said Dr. James V. Rawson, Chair of the Medical College of Georgia Department of Radiology at Georgia Health Sciences University. Rawson and Dr. Ruth Carlos, Professor ...

Tobacco contains highly toxic compounds not regulated by law

Tobacco contains highly toxic compounds not regulated by law
2012-10-01
Researchers from the University of Alicante (Spain) have analysed ten brands of cigarettes and found that the concentrations of certain harmful and carcinogenic substances vary significantly from one brand to another. Until now legislation has not covered these compounds and only establishes limits for nicotine, tar and carbon monoxide. Scientists have also developed catalysts to reduce the harmful products in tobacco. In accordance with current legislation, cigarette packets indicate the nicotine, tar and carbon monoxide concentrations in order to confirm that these ...

Camels give President Obama's Alzheimer's plan a lift

2012-10-01
Bethesda, MD—President Obama's national plan to fight Alzheimer's disease just got a lift thanks to a team of international researchers whose recent discovery may lead to enhanced imaging of and improved drug delivery to the brain. A research report appearing in The FASEB Journal, describes an entirely new class of antibody discovered in camelids (camels, dromedaries, llamas, and alpacas) that is able to cross the blood-brain barrier, diffuse into brain tissue, and reach specific targets. Having such antibodies, which are naturally available, may be part of a "game changer" ...

Therapeutic time window important factor for cord blood cell transplantation after stoke

2012-10-01
Putnam Valley, NY. (Oct. 1, 2012) – A research team from Germany has found that optimal benefit and functional improvement for ischemic stroke results when human umbilical cord blood mononuclear cells (hUCB MNCs) are transplanted into rat stroke models within 72 hours of the stroke. Their study is published in the current issue of Cell Transplantation (21:6), now freely available on-line at: http://www.ingentaconnect.com/content/cog/ct/. "Ischemic stroke is one of the most frequent causes of death and the most common reason for permanent disabilities in adults in ...
