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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
