ROCHESTER, Minn. -- In the May issue of Mayo Clinic Proceedings, physician experts review current practices for pain management in cirrhotic patients. The physician experts reviewed all current literature available on PubMed and MEDLINE with no limits in the search to recommend a uniform and practical guide to approaching analgesia in the cirrhotic patients.

Imagine you could work out the answer to a question, without knowing what the question was. For example, suppose someone thinks of two numbers and then asks another person to work out their sum, without letting them know what the two numbers are. However, they are given an encryption of the two numbers but not told how to decrypt them.

Providing single lens distance glasses to older people who wear multifocal glasses and who regularly take part in outdoor activities is a simple and effective way of preventing falls, concludes a study published on bmj.com today.

However, the researchers warn that this strategy may not be appropriate for frailer people who spend more time indoors.

Fish alter their movements when under threat from predators to keep closer together and to help them to blend into the crowd, according to new research headed by scientists at the University of York.

Researchers in the York Centre for Complex Systems Analysis (YCCSA), based in the University's Department of Biology, used a combined computer simulation and experimental study of group behaviour to discover that shoaling fish co-ordinate their movements more frequently when under threat.

CAMBRIDGE, Mass. -- The majestic animals most closely associated with the African savanna -- fierce lions, massive elephants, towering giraffes -- may be relatively minor players when it comes to shaping the ecosystem.

EAST LANSING, Mich. — Older patients battling pneumonia spent less time in the hospital when treated using osteopathic manipulative medicine – a drug-free form of hands-on medical care focusing on increasing muscle motion – in addition to conventional care, recently published research shows.

Kari Hortos, a Michigan State University professor in the College of Osteopathic Medicine's Department of Internal Medicine, was one of seven site investigators as part of the five-state Multicenter Osteopathic Pneumonia Study in the Elderly.

Recent findings suggest that bacteria residing in the the human intestinal tract may be associated with an individual's risk of developing colon cancer. Scientists from the University of Florida present their research today at the 110th General Meeting of the American Society for Microbiology in San Diego, CA.

CAMBRIDGE, Mass., May 24, 2010 – Hailed as a "cross between a high-speed centrifuge and a cotton candy machine," bioengineers at Harvard have developed a new, practical technology for fabricating tiny nanofibers.

Rice University researchers have discovered thin films of nanotubes created with ink-jet printers offer a new way to make field-effect transistors (FET), the basic element in integrated circuits.

While the technique doesn't exactly scale down to the levels required for modern microprocessors, Rice's Robert Vajtai hopes it will be useful to inventors who wish to print transistors on materials of any kind, especially on flexible substrates.

"With this methodology an exact model of the monuments or places of interest can be obtained in a virtual way", Pedro Martín-Lerones, co-author of the study and researcher at the Cartif Foundation in the Technological Park of Boecillo (Valladolid), explains to SINC.

A novel study by researchers at the University of California, San Francisco found that nearly one-third of Rheumatoid Arthritis (RA) patients differed from their physicians in assessment of their disease severity. The disagreement between patient and doctor evaluation of RA activity was most prevalent in patients with depressive symptoms, and those who had poor overall function.

Patients researching health conditions on the internet should use reputable and frequently updated websites and not see online research as a replacement for consulting healthcare professionals, according to a paper in the May issue of the Journal of Clinical Nursing. A research review carried out by a team from the University of Florida, USA, found that 86 per cent of adult patients use the internet to get answers to health-related questions, but only 28 to 41 per cent consult primary healthcare providers about the information they find out. "This discrepancy suggests that the majori

The effective use of contraception once becoming sexually active is the best way to avoid unwanted pregnancy during adolescence. This is just one of the conclusions of a study by the Spanish National Research Council (CSIC) and the Universidad Complutense in Madrid which additionally reveals that using no contraception or using it well after starting sexual relations increases up to six times the risk for teen pregnancy.

Washington - The American Academy of Physician Assistants (AAPA) and the American College of Physicians (ACP) today released a policy monograph that supports the critical roles physician assistants (PAs) and physicians play in improving access to high-quality primary care. The paper, "Internists and Physician Assistants: Team-based Primary Care," results from a months-long collaborative project.
