| Burden of osteoporotic fractures increases dramatically in the Middle East and Africa Posted: 22 Oct 2011 01:10 PM PDT Osteoporosis is a serious and growing problem throughout the Middle East and parts of Africa, according to new research. Gathering data from 17 countries in the region as well as Turkey, "The Middle East & Africa Regional Audit" is a landmark report examining epidemiology, costs and burden in individual countries as well as collectively across the region.  |
| More African-Americans burdened by osteoarthritis in multiple large joints Posted: 21 Oct 2011 04:47 AM PDT New research suggests African-Americans have a higher burden of multiple, large-joint osteoarthritis (OA), and may not be recognized based on the current definition of "generalized OA." African-Americans were also more likely to have knee OA, but less likely to be affected by hand OA than Caucasians according to new findings.  |
| NIPPV linked to increased hospital mortality rates in small group of patients Posted: 21 Oct 2011 04:47 AM PDT Although increased use of noninvasive positive-pressure ventilation (NIPPV) nationwide has helped decrease mortality rates among patients hospitalized with chronic obstructive pulmonary disease (COPD), a small group of patients requiring subsequent treatment with invasive mechanical ventilation (IMV) have a significantly higher risk of death than those placed directly on IMV, according to researchers in the United States who studied patterns of NIPPV use.  |
| New instrument helps researchers see how diseases start and develop in minute detail Posted: 21 Oct 2011 04:45 AM PDT Researchers can now study molecules which are normally only found in very small concentrations, directly in organs and tissue. Researchers have now managed to construct an instrument that 'hyperpolarises' the molecules and thus makes it possible to track them using MRI. The technology opens up new possibilities to study what really happens on molecular level in organs such as the brain.  |
| Sewage contains the greatest diversity of unidentified viral populations known to date Posted: 21 Oct 2011 04:45 AM PDT Raw sewage provides a perfect ecosystem for studying the diversity of viral populations that remain uncharacterized. A pioneering study, which applies metagenomics to the analysis of viral populations present in sewage, reveals that the viral universe is far larger than previously thought.  |
