FDA to reduce medical radiation exposure

FDA to reduce medical radiation exposure

WASHINGTON - The U.S. Food and Drug Administration says it is starting a program designed to reduce unnecessary medical radiation exposure. The FDA said its initiative will focus on three types of imaging procedures: computed tomography, nuclear medicine and fluoroscopy. Those procedures, officials said, are the greatest contributors to total U.S. radiation exposure and use much higher radiation doses than other radiographic procedures, such as standard X-rays, dental X-rays and mammography. Although the medical imaging proce- dures have led to early disease diagnoses that help save lives, the FDA said the imaging technology, as do all med- ical procedures, pose some risks. "The amount of radiation Americans are exposed to from medical imaging has dramatic- ally increased over the past 20 years," said Dr. Jeffrey Shuren, director of the FDA's Center for Devices and Radio- logical Health. "The goal of FDA's initiative is to support the benefits associated with medical imaging, while mini- mizing the risks." The federal agency said its initiative will promote the safe use of medical imaging devices, support informed clinical decision-making, and increased patient awareness of their own exposure. The FDA said it also intends to issue requirements for manufacturers of imaging devices to incorporate safeguards into the design of their machines to develop safer technologies. The agency said it will hold a public meeting March 30-31 to solicit input on what requirements to establish.

Malaria parasite genome studied

Malaria parasite genome studied

SINGAPORE - Scientists at Singapore's Nanyang Technological University say they have completed the world's first in- depth study of the malaria parasite genome. The researchers at the university's School of Biological Sciences said their findings could lead to the development of more potent drugs or even a vaccine for malaria, which is transmitted to humans by infected mosquitoes and kills up to three million people each year. Assistant Professor Zbynek Bozdech, who led the study, said his team has become the first to successfully use transcriptional profiling to uncover previously unknown gene expression patterns in malaria. They said transcrip- tional profiling is the measurement of the activity of thousands of genes at once, to create a global picture of cellular function. Their findings, the scientists said, have yielded critical information about how the malaria parasite Plasmodium falciparum responds to existing compounds with curative potential. "Drawing on our findings, pharmaceutical companies could explore ways to design a drug that targets the weakest link," said Bozdech. "We have predicted all the genes that could be used for a vaccine as well." The study was reported in the January edition of the journal Nature Biotechnology.
