Rise In Homicide By Mentally Ill In England And Wales
The number of people killed by individuals suffering from mental illness in England and Wales increased between 1997 and 2005, figures show. The rise occurred in people who were not under mental health care and was not found in mental health patients.

Illinois Counties Facing Increases In STDs Among Teenagers; Bill Aims To Reduce Rates
Illinois health officials contend that images seen in the media, social influences, and a lack of "frank" discussion on STDs in schools, among other issues, might be contributing to increases in STD rates across the state, the State Journal-Register reports. "According to recently released data, new cases of chlamydia in Illinois reached an all-time high statewide in 2008 - 59,169 - while the number of gonorrhea cases outside Chicago has been rising in recent years and totaled 10,165 in 2008," the Journal-Register reports. In addition, about 35,000 state residents have HIV/AIDS, the article states. Charlie Rabins, chief of the STD program at the Illinois Department of Public Health, said a bill (SB 212) currently awaiting Gov. Pat Quinn"s (D) approval might help reduce STD rates. The bill "would allow what is called "expedited partner therapy," in which medical professionals who treat patients for gonorrhea or chlamydia can give those patients single-dose antibiotics to pass on to sexual partners without first examining the partners," according to the Journal-Register (Olsen, 7/27).

Work Status Changes More Common Among Women Receiving Chemotherapy For Breast Cancer, Study Says
Women with breast cancer who receive chemotherapy appear more likely than those treated with radiation therapy to experience a major change in work status, according to a study published in the journal Cancer, Reuters reports. For the study, Dana-Farber Cancer Institute researcher Michael Hassett and colleagues used a large health insurance claims database to identify 3,233 women who were first diagnosed with breast cancer between 1998 and 2002. All of the women were younger than age 64, insured, and working full time or part time as of diagnosis. About 54% of the women received chemotherapy, and 58% received radiation therapy.Hassett said that most of the women did "not experience a significant change in their employment after cancer diagnosis and treatment." However, of the 6.6% who experienced such a change, those who received chemotherapy had a 1.8-fold greater risk of leaving work, retiring or going on long-term disability leave in the subsequent year. Sixty-seven percent of women who experienced a change went from full-time employment to early retirement, while the rest went from full-time employment to long-term disability or retirement, or their status was unknown. Although the study looked at many factors, only chemotherapy and older age were associated with an increased likelihood of a change in employment. Hassett said that most of the participants in the study worked for large employers that offered health insurance. He added that further research is needed to evaluate the effect of cancer diagnosis and treatment on work status for women who are self-employed or work for smaller companies (Hendry, Reuters, 6/30).

NIST Researchers 'All Aglow' Over New Test Of Toxin Strength

A new National Institute of Standards and Technology (NIST) assay using a "glow or no glow" technique may soon help the U.S. Department of Homeland Security (DHS) defend the nation against a spectrum of biological weapons that could be used in a terrorist attack. One very dangerous toxin on the list is ricin, a protein derived from castor beans that is lethal in doses as small as 500 micrograms - about the size of a grain of salt. As part of its efforts to address the threat, DHS is working with NIST to create a standardized ricin sample with a known potency. Such a standard is needed both to check the accuracy of detection equipment, and, should an attack occur, to confirm the success of decontamination procedures. A major step toward this goal - the development of a rapid, reliable and precise assay of the potency of a ricin sample - has now been achieved by NIST scientists. As detailed in an article posted online this week in Assay and Drug Development Technologies,* the new NIST assay uses a commercially available cell line genetically engineered to produce large amounts of green fluorescent protein (GFP). Ricin shuts down ribosomes - the protein manufacturing factories of a cell. Assay cells exposed to the toxin will quickly stop synthesizing GFP. This, in turn, will result in a measurable decrease in fluorescence - a drop that correlates directly to the strength of the ricin present. The NIST assay yields many advantages over traditional cytotoxicity measuring systems, including: a highly sensitive response to ricin (as little as 1 nanogram per milliliter) within six rather than 24 hours; detection of the toxin long before significant cell death has occurred; results that are highly reproducible; no need for the addition of any reagents; and the flexibility to measure the potency of other ribosome inhibitors, even nanoparticles, with the same precision as ricin. Notes: Partial support for this work was provided by the DHS Science and Technology Directorate. * M. Halter, J.L. Almeida, A. Tona, K.D. Cole, A.L. Plant and J.T. Elliott.
