Sleeping in dentures doubles the risk of pneumonia in the elderly

MEDICINE & HEALTH Alexandria, Va., USA - Poor oral health and hygiene are increasingly recognized as major risk factors for pneumonia among the elderly. To identify modifiable oral health-related risk factors, lead researcher Toshimitsu Iinuma, Nihon University School of Dentistry, Japan, and a team of researchers prospectively investigated associations between a constellation of oral health behaviors and incidences of pneumonia in the community-living of elders 85 years of age or older. This study, titled "Denture Wearing During Sleep Doubles the Risk of Pneumonia in Very Elderly," has been published by the International and American Associations for Dental Research (IADR/AADR in the OnlineFirst portion of the Journal of Dental Research (JDR).

New at-risk group identified for gastrointestinal stromal tumors

Researchers at the University of California, San Diego School of Medicine have, for the first time, clearly defined the epidemiology of gastrointestinal stromal tumors (GIST), which occur primarily in the lining of the stomach and small intestine. One key finding: Patients of Asian descent, who have not previously been identified as an at-risk population, are 1.5 times more likely than other patient groups to be diagnosed with this type of tumor. Results of the study were published this week in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

The Skin Cancer Selfie

Melanoma is the fifth most common cancer type in the United States, and it's also the deadliest form of skin cancer, causing more than 75 percent of skin-cancer deaths.
