HPV testing followed by cytology and repeat HPV testing may improve cervical cancer screening

The use of human papillomavirus (HPV) DNA testing as an initial screening step followed by triage with a standard Pap test (cytology) and repeat HPV DNA testing may increase the accuracy of cervical cancer screening, according to a study in the Jan. 13 online issue of the Journal of the National Cancer Institute. Compared to cytology alone, the screening strategy improved detection of precancerous...

Journal Chest: January news briefs

News briefs from the January issue of CHEST highlight studies related to the use of compression devices for restless legs syndrome, COPD and depression, and improved HIV survival rates.

Low-cost strategy developed for curbing computer worms

A new, cost-effective strategy to limit the spread of worms through computer networks has been developed by researchers at UC Davis and Intel Corp. The two-pronged plan compiles suspicious incoming activity from the network's computers to create an early-warning system for worm attacks. As the threat level rises and falls, an algorithm determines whether to toggle computers online or offline...

Meta-analysis confirms value of risk-reducing salpingo-oophorectomy for women with BRCA mutations

Prophylactic salpingo-oophorectomy -- removal of the ovaries and fallopian tubes -- reduces the relative risk of breast cancer by approximately 50 percent and the risk of ovarian and fallopian tube cancer by approximately 80 percent in women who carry a mutation in the BRCA1 or BRCA2 gene, researchers report in the Jan. 13 online issue of the Journal of the National Cancer Institute.

Misuse of Vicks VapoRub may harm infants and toddlers

New research appearing in the January issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians, shows that Vicks VapoRub may stimulate mucus production and airway inflammation, which can have severe effects on breathing in an infant or toddler.

MyFitness Planner really moves you

A study led by Genevieve Fridlund Dunton, Ph.D., M.P.H., a Cancer Prevention Fellow at the National Cancer Institute, indicated that Dairy Council of California's free MyFitness Planner online tool helped women achieve 37 minutes of increased walking and 48 minutes of increased total moderate-to-vigorous physical activity each week compared to a control group. Study results were published in the...

New co-chair of atomic scientists calls on US administration to reduce nuclear threat

Lawrence Krauss, a theoretical physicist and cosmologist at Arizona State University, will co-chair the Board of Sponsors of the Bulletin of Atomic Scientists with Nobel Laureate Leon Lederman. Together they plan to re-energize a national discussion on the reduction of nuclear weapons stockpiles, and a commitment to fight proliferation and encourage disarmament efforts.

New digital map of Africa's depleted soils to offer insights critical for boosting food production

Responding to sub-Saharan Africa's soil health crisis, the International Center for Tropical Agriculture announced today an ambitious new effort to produce the first-ever, detailed digital soil map for all 42 countries of the region. This project combines the latest soil science and technology with remote satellite imagery and on-the-ground efforts to analyze thousands of soil samples from remote...

Novel drugs selectively target pathway important in rheumatoid arthritis

Methotrexate , a folate antagonist that blocks folic acid activity, is the most widely used disease-modifying antirheumatic drug for rheumatoid arthritis. It enters the cell via several pathways, one of which involves folate receptor β, which is highly specific for cells present in the joints of patients with rheumatoid arthritis.

Novel technique changes lymph node biopsy, reduces radiaiton exposure

Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients. For the first time, Washington University in St. Louis researchers Lihong Wang and Younan Xia, have used gold nanocages to map sentinel lymph nodes in a rat noninvasively using PAT. Wang's lab is the largest PAT lab in the world, credited with the invention of...

Race and gender determine how politicians speak

Race and gender influence the way politicians speak, which is not always to their advantage. Camelia Suleiman from Florida International University and Daniel O'Connell from Georgetown University in the US have come to this conclusion as a result of their findings, published online in Springer's Journal of Psycholinguistic Research.

RAND launches unique tool to evaluate health reform proposals

Like our health-care system itself, the subject of health-care reform is complex. Every policy prescription to solve one problem will ripple through the system in ways not easily seen or understood. RAND Health created COMPARE in recognition of these complexities and the need for an unbiased source to aid policymakers with the reform efforts ahead.

Researchers identify another potential biomarker

Researchers from Boston University School of Medicine have demonstrated that a recently discovered class of molecule called microRNA (miRNAs), regulate the gene expression changes in airway cells that occur with smoking and lung cancer. These findings, which appear in the on-line early edition of journal Proceedings of the National Academy of Sciences, may lead to a new, relatively noninvasive...
