About one-fifth of women, less than 7 percent of men report use of indoor tanning

Women are more likely to report use of indoor tanning facilities than men, and some characteristics common to indoor tanners differ by sex, according to a report in the December issue of Archives of Dermatology, one of the JAMA/Archives journals. However, few tanners—male or female—mention avoiding tanning beds when asked about ways to reduce skin cancer risk.

Most patients can speak and swallow after combination treatment for head and neck cancer

Most patients do not have ongoing speaking or swallowing difficulties following combined chemotherapy and radiation treatment for advanced head or neck cancer, but several factors may be associated with worse outcomes in these functions, according to a report in the December issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.

Outcomes after recurrence of oral cancer vary by timing, site

Patients who have recurrence of oral squamous cell carcinoma tend to do worse if the new cancer appears at the same site early or if it appears in the lymph nodes six months or longer after initial treatment, according to a report in the December issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.

Factors linked to speech/swallowing problems after treatment for head and neck cancers

DURHAM, NC – Most patients with locally advanced head and neck cancers who successfully complete treatment with chemotherapy and radiation manage to do so without losing the ability to speak clearly and swallow comfortably, according to researchers at the Duke Cancer Institute.

"This is good news," said Joseph K. Salama, MD, an assistant professor of radiation oncology at Duke and the corresponding author of the study. "I hope it brings some comfort to newly-diagnosed patients who are understandably worried about what long-term effects treatment might involve."

Blacks with liver cancer more likely to die, study finds

ANN ARBOR, Mich. — Black people with early stage liver cancer were more likely than white patients to die from their disease, according to a new study from the University of Michigan Comprehensive Cancer Center.

Five years after diagnosis, 18 percent of white liver cancer patients were alive but only 15 percent of Hispanic patients and 12 percent of black patients were. Median survival times ranged from 10 months for whites and Hispanics to 8 months for blacks.

Study: Natural supplement may reduce common-cold duration by only half a day

MADISON — An over-the-counter herbal treatment believed to have medicinal benefits has minimal impact in relieving the common cold, according to research by the University of Wisconsin-Madison School of Medicine and Public Health.

Ocean acidification changes nitrogen cycling in world seas

Ocean acidification changes nitrogen cycling in world seas

Increasing acidity in the sea's waters may fundamentally change how nitrogen is cycled in them, say marine scientists who published their findings in this week's issue of the journal Proceedings of the National Academy of Sciences (PNAS).

Intensive chemotherapy can dramatically boost survival of older teenage leukemia patients

More effective risk-adjusted chemotherapy and sophisticated patient monitoring helped push cure rates to nearly 88 percent for older adolescents enrolled in a St. Jude Children's Research Hospital acute lymphoblastic leukemia (ALL) treatment protocol and closed the survival gap between older and younger patients battling the most common childhood cancer.

Research shows that environmental factors limit species diversity

It's long been accepted by biologists that environmental factors cause the diversity—or number—of species to increase before eventually leveling off. Some recent work, however, has suggested that species diversity continues instead of entering into a state of equilibrium. But new research on lizards in the Caribbean not only supports the original theory that finite space, limited food supplies, and competition for resources all work together to achieve equilibrium; it builds on the theory by extending it over a much longer timespan.

Study identifies cells that give rise to brown fat

BOSTON – December 20, 2010 – In some adults, the white fat cells that we all stockpile so readily are supplemented by a very different form of fat—brown fat cells, which can offer the neat trick of burning energy rather than storing it. Researchers at Joslin Diabetes Center, which last year led the way in demonstrating an active role for brown fat in adults, now have identified progenitor cells in mouse white fat tissue and skeletal muscle that can be transformed into brown fat cells.

New study examines immunity in emerging species of a major mosquito carrer of malaria

In notable back-to-back papers appearing in the prestigioous journal Science in October, teams of researchers, one led by Nora Besansky, a professor of biological sciences and a member of the Eck Institute for Global Health at the University of Notre Dame, provided evidence that Anopheles gambiae, which is one of the major mosquito carriers of the malaria parasite in Sub-Saharan Africa, is evolving into two separate species with different traits.

The orange in your stocking: researchers squeezing out maximum health benefits

 researchers squeezing out maximum health benefits

The team published the best health-promoting combinations of those natural antioxidants in a recent issue of the Journal of Food Science. The paper's lead author, Brenner Freeman, was a BYU undergrad when he conducted the research.

Now applying to medical schools, Brenner chose to study oranges because he was raised on a citrus orchard in Arizona.
