(Press-News.org) Most HIV-positive patients die of cancer. In the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2011; 108[8]: 117), Manfred Hensel's research group presents epidemiological data.
The authors surveyed all German hospital outpatient clinics and ambulatory care centers specializing in the treatment of HIV patients in the period from 2000 to 2007 and were thus able to analyze the largest collection of data on the incidence of cancer in HIV patients ever assembled in Germany. It first became clear in the early 1980s that HIV infection is associated with malignancies. Kaposi sarcoma, cervical cancer, and non-Hodgkin's lymphoma were found particularly often in immune-deficient populations. These "Aids-defining" tumors have since become less frequent, but other types of cancer such as anal carcinoma, Hodgkin's lymphoma, lung cancer, and skin cancer are coming to the fore. Because most patients infected with HIV die of these malignancies, the authors recommend tumor screening for HIV-positive persons.

Boston researchers create 'SMArt' platform architecture, launch $5,000 health app competition
2011-03-09
Boston, Mass. – Through a grant from the Office of the National Coordinator for Health Information Technology (ONC), researchers at Children's Hospital Boston and Harvard Medical School have developed a first-of-its kind platform architecture to support a flexible health information technology (IT) environment and promote innovation. The SMArt (Substitutable Medical Applications, reusable technologies) platform and interface are being made publicly available today to kick off the start of a $5,000 competition challenging developers to create web applications that provide ...
Research finds open-source software is actually more secure for health care IT
2011-03-09
Globally the sale of health care information systems is a multibillion dollar industry. The vast costs, frequent failed systems, and inability of systems to talk to each other regularly attract media comment. However policy makers still shy away from a class of software, Open Source, that could address many of these problems, because of worries about the safety and security of Open Source systems. Now new research by the University of Warwick's Institute for Digital Healthcare, and the Centre for Health Informatics and Multiprofessional Education at UCL Medical School, ...
Identifying 'anonymous' email authors
2011-03-09
Montreal, March 8, 2011 – A team of researchers from Concordia University has developed an effective new technique to determine the authorship of anonymous emails. Tests showed their method has a high level of accuracy – and unlike many other methods of ascertaining authorship, it can provide presentable evidence in courts of law. Findings on the new technique are published in the journal Digital Investigation.
"In the past few years, we've seen an alarming increase in the number of cybercrimes involving anonymous emails," says study co-author Benjamin Fung, a professor ...
Spanish tourists criticize other Mediterranean countries' lack of hospitality
2011-03-09
People visiting Spain have a high opinion of the price-quality ratio of Spanish hotels. Spanish tourists, on the contrary, complain about the quality of hotels, cleanliness and hospitality in countries such as Italy, Greece and France. This is one of the conclusions of a study carried out by the University of Cádiz (UCA) on tourism in southern Mediterranean countries.
"The five aspects most-highly rated by tourists travelling in the countries of the European Mediterranean are the leisure-spectacle activities, organised routes-excursions, cultural activities, the weather ...
Aging with grace: In-home assessments lead to better care, lower health costs
2011-03-09
INDIANAPOLIS – The March 2011 issue of the journal Heath Affairs highlights an evidence-based model of geriatric care management developed, implemented and tested by researchers and clinicians from Indiana University, the Regenstrief Institute and Wishard Health Services.
Geriatric Resources for Assessment and Care of Elders (GRACE) optimizes the health and functional status of community dwelling lower income, older adults. GRACE is now in use by Wishard Health Services, the third-largest safety-net health organization in the United States; by HealthCare Partners Medical ...
Oops -- graphene oxide's solubility disappears in the wash
2011-03-09
Graphene Oxide has had a scrum of researchers fall upon it as it retains much of the properties of the highly valued super material pure Graphene, but it is much easier, and cheaper, to make in bulk quantities; easier to process; and its significant oxygen content appears to make it soluble in water. However new research led by University of Warwick Chemist Dr Jonathan P. Rourke and Physicist University of Warwick Physicist Dr Neil Wilson, has found that that last assumption is incorrect and unfortunately Graphene oxide's solubility literally comes out in the wash.

The cerebellum provides clues to the nature of human intelligence
2011-03-09
Milan, Italy, 8 March 2011 – Research suggests that intelligence in humans is controlled by the part of the brain known as the 'cortex', and most theories of age-related cognitive decline focus on cortical dysfunction. However, a new study of Scottish older adults, reported in the April 2011 issue of Elsevier's Cortex (http://www.sciencedirect.com/science/journal/00109452), suggests that grey matter volume in the 'cerebellum' at the back of the brain predicts cognitive ability, and keeping those cerebellar networks active may be the key to keeping cognitive decline at ...
MU chemist discovers shortcut for processing drugs
2011-03-09
COLUMBIA, Mo. – A prolific University of Missouri chemist has discovered a quicker and easier method for pharmaceutical companies to make certain drugs.
Jerry Atwood, Curator's Professor and Chair of the Department of Chemistry in the MU College of Arts and Science, has recently published a paper – his 663rd in a refereed journal – that states that highly pressurized carbon dioxide at room temperature could replace the time consuming and expensive methods currently used to manufacture certain pharmaceutical drugs.
In the article, "A New Strategy of Transforming Pharmaceutical ...
Study shows no-till's benefits for Pacific Northwest wheat growers
2011-03-09
This release is available in Spanish.
Wheat farmers in eastern Oregon and Washington who use no-till production systems can substantially stem soil erosion and enhance efforts to protect water quality, according to research by U.S. Department of Agriculture (USDA) scientists.
Agricultural Research Service (ARS) hydrologist John Williams led a study that compared runoff, soil erosion and crop yields in a conventional, intensively tilled winter wheat-fallow system and a no-till 4-year cropping rotation system. ARS is USDA's chief intramural scientific research agency, ...
Right-handers, but not left-handers, are biased to select their dominant hand
2011-03-09
Milan, Italy, 8 March 2011 – The vast majority of humans – over 90% – prefer to use their right hand for most skilled tasks. For decades, researchers have been trying to understand why this asymmetry exists. Why, with our two cerebral hemispheres and motor cortices, are we not equally skilled with both hands? A study from the University of Aberdeen in the UK, published in the April 2011 issue of Elsevier's Cortex (http://www.sciencedirect.com/science/journal/00109452), suggests that the explanation may stem from actions that require us to use both hands at the same time, ...
