A research team led by epidemiologists from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, analyzed hospital discharge records of patients in 11 states whose combined total population represents 42 percent of the country.
They reviewed database records spanning 1998 to 2005, and identified more than 16,475 hospitalizations associated with pulmonary NTM in people without AIDS. Before the widespread availability of combination antiretroviral therapy, pulmonary NTM disease was a common opportunistic infection among people with AIDS infection; in this study, the researchers limited their analysis to non-AIDS NTM disease.
Of the 11 states studied, Florida, New York and California had 62 percent of the pulmonary NTM hospitalizations. The scientists chose these states to compare trends by geographic area. They found the annual prevalence of disease increased significantly among men and women in Florida (3.2 percent per year for men and 6.5 percent per year for women) and among women in New York (4.6 percent per year). There were no significant changes in California. Whether these geographic differences in prevalence are a result of exposure to NTM, or increased concentrations of mycobacterium in certain environments, or both, is not clear. However, previous studies have found high disease prevalence in the southeastern United States, particularly along the coastal regions of the Atlantic and Gulf coasts.
Study results show pulmonary NTM has increased in certain geographic areas of the United States, and while overall prevalence is higher in women, prevalence increases for both sexes in the fifth or sixth decade of life. Further research is needed to define the prevalence of the disease in nonhospitalized people in regions throughout the United States and to determine risk factors for disease susceptibility, including genetic and environmental factors.

NIAID conducts and supports research—at NIH, throughout the United States, and worldwide—to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News releases, fact sheets and other NIAID-related materials are available on the NIAID Web site at http://www.niaid.nih.gov.
The National Institutes of Health (NIH)—The Nation's Medical Research Agency—includes 27 Institutes and Centers and is a component of the U. S. Department of Health and Human Services. It is the primary federal agency for conducting and supporting basic, clinical and translational medical research, and it investigates the causes, treatments and cures for both common and rare diseases.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
