In this week's PLoS Medicine, Groesbeck Parham from the Centre for Infectious Disease Research in Zambia, and colleagues describe their Cervical Cancer Prevention Program, which has provided services to over 58,000 women over the past five years. The authors share lessons learned from the program's implementation and its integration with existing HIV/AIDS programs, aiming to help other cervical cancer prevention initiatives succeed in the developing world and avoid placing additional burdens on health systems.

ATS 2011, DENVER –Face masks worn by patients infected with tuberculosis (TB) may be able to significantly cut transmission rates to non-infected patients, according to a new study by researchers from the U.S. and South Africa. The study was conducted in a specialized airborne infections research facility in South Africa, which was designed to allow study of methods to control the spread of TB. Transmission rates were measured using healthy guinea pigs exposed to infected patients.

The results of the study will be presented at the ATS 2011 International Conference in Denver.

Although some evidence suggests that prevention of vitamin A deficiency among women in developing countries may improve maternal and infant survival, pregnant women in rural Bangladesh who received vitamin A or beta carotene supplementation in a randomized trial did not have a lower rate of all-cause maternal, fetal, or infant death, compared to women who received placebo, according to a study in the May 18 issue of JAMA.

Boston, MA – Men who regularly drink coffee appear to have a lower risk of developing a lethal form of prostate cancer, according to a new study led by Harvard School of Public Health (HSPH) researchers. What's more, the lower risk was evident among men who drank either regular or decaffeinated coffee.

The study will be published May 17, 2011, in an online edition of the Journal of the National Cancer Institute.

Researchers at the University of Texas Medical Branch at Galveston and the University of California-San Diego School of Medicine have published a study that offers a new understanding of a protein critical to physiological processes involved in major diseases such as diabetes and cancer. This work could help scientists design drugs to battle these disorders.

The article was deemed a "Paper of the Week" by and will be on the cover of the Journal of Biological Chemistry. It is scheduled for publication May 20 and now available online.

New findings show that treatment with a specific alpha blocker helps reduce symptoms and improve quality of life for men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

The alpha-blocker, known as silodosin, works by selectively relaxing the muscles in the bladder neck and prostate. The treatment is already approved in Canada, the United States, the EU and Japan to treat painful symptoms of another prostate gland condition, benign prostatic hyperplasia, commonly referred to as an enlarged prostate.

May 17, 2011 -- In New York City, the prevalence of asthma among children entering school varies by neighborhood anywhere from 3% to 19%, and children growing up within walking distance of each other can have 2-3 fold differences in risk for having asthma. In the first comprehensive effort to understand what drives these localized differences, researchers at Columbia University's Mailman School of Public Health compared the household presence of cockroach, mouse, cat, dust mite and other allergens in neighborhoods with a high prevalence of asthma to that in low-prevalence neighborhoods.

ATS 2011, DENVER –A new study links the intermittent interruption of breathing that occurs in patients with obstructive sleep apnea (OSA) to enhanced proliferation of melanoma cancer cells and increased tumor growth in mice, according to researchers in Spain. The study also found tumor cells of OSA mouse models tended to contain more dead cells, indicating a more aggressive type of cancer.

The results of the study will be presented at the ATS 2011 International Conference in Denver.

(Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have developed new methods for studying how environmental factors and climate affect giant kelp forest ecosystems at unprecedented spatial and temporal scales.

The scientists merged data collected underwater by UCSB divers with satellite images of giant kelp canopies taken by the Landsat 5 Thematic Mapper. The findings are published in the feature article of the May 16 issue of Marine Ecology Progress Series.

The development and successful testing of a method for unreeling the strands of silk in wild silkworm cocoons could clear the way for establishment of new silk industries not only in Asia but also in vast areas of Africa and South America. The report appears in ACS' journal Biomacromolecules.

A tropical forest is easy to cut down, but getting it back is another story. In a special issue of the journal Forest Ecology and Management, leading researchers at the Smithsonian in Panama and across Latin America offer new insights on reforestation based on 20 years of research.

Whether sex education focuses only on abstinence or teaches students about contraception and other topics as well, it all shares one main message: Wait. In abstinence-only, students are exhorted to wait for sex until they're married. In "comprehensive" or "abstinence-plus," the idea is to delay sexual relations until . . . later.

The USDA Forest Service and the Southern Group of State Foresters released the first phase of the Southern Forest Futures Project report on Tuesday, May 17, which identifies areas forest managers will focus on to maintain southern forests in the coming years.

Researchers at the University of Alberta have taken an important step in understanding an immune system of bacteria, a finding that could have implications for medical care and both the pharmaceutical and dairy industries.

To understand the long-term effects of a prolonged tropical storm in the Panama Canal watershed, Robert Stallard, staff scientist at the Smithsonian Tropical Research Institute and research hydrologist at the U.S. Geological Survey, and Armando Ubeda, the LightHawk Mesoamerica program manager, organized four flights over the watershed to create a digital map of landslide scars.
