Direct-to-consumer (DTC) prescription drug advertising – a $3.2 billion industry in the United States – not only sways patients to ask for certain medications, but profoundly influences the way doctors make initial treatment decisions, according to an April 27 study in the Journal of the American Medical Association.
University of Rochester Medical Center Professor Ronald M. Epstein, M.D., had a lead role in the research, which focused on antidepressants, as they consistently rank among the top advertised drugs. The study showed that doctors prescribed antidepressants far more often when patients asked for them. Furthermore, the study revealed that consumer advertising may have competing effects on health-care quality, by promoting the overuse of drugs in some cases while also averting under use and raising consumer awareness of disease.
The study was a collaborative effort between the UR Department of Family Medicine and University of California, Davis, Center for Health Services. The corresponding author is Richard L. Kravitz, M.D., MSPH, at UC/Davis.

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...
