Do drug therapies raise risk of bladder cancer?

28.10.2009
Dartmouth studies glucorticoid side effects

In her most recent study of possible triggers of cancer among northern New England residents, Dartmouth epidemiologist Margaret R. Karagas, Ph.D., and her team identified an enhanced risk to the bladders of patients taking drugs that suppress the immune system.

The findings, from a population-based, case-control study in New Hampshire, appear in the September 2009 issue of the British Journal of Cancer, with Dartmouth Medical School student Karl Dietrich as first author, with DMS professors Alan R. Schned, M.D., and John A. Heaney, M.D., as co-authors, and with Karagas, a professor of community and family medicine at DMS, as principal investigator.

The report examines the long-term use of glucocorticoids by 786 bladder-cancer patients and by 1,083 control subjects. Doctors commonly prescribe a combination of cytotoxic drugs and glucocorticoids as immunosuppressive therapy to help recipients of transplants avoid rejection of their new organs, and patients with rheumatoid arthritis, asthma, and other conditions often take glucocorticoids. Previous research, in some of which Karagas participated, has shown associations between such drug therapies and higher risk of skin cancer and lymphoma. A similar risk for bladder cancer, the new report says, "might indicate the need for closer monitoring of individuals who regularly take glucocorticoids."

In addition to teaching epidemiology, Karagas is section head of biostatistics and epidemiology at DMS, and co-director of the Norris Cotton Cancer Center's epidemiology and chemoprevention program. Schned is a professor of pathology and acting chair of that department at the medical school, where Heaney is a professor of surgery specializing in urology.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

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...

Im Focus: AchemAsia 2019 will take place in Shanghai

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...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

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.

Im Focus: Sharp images with flexible fibers

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...
