Sorting cells with sound waves

Separating cells with sound offers a gentler alternative to existing cell-sorting technologies, which require tagging the cells with chemicals or exposing them to stronger mechanical forces that may damage them. “Acoustic pressure is very mild and much smaller in terms of forces and disturbance to the cell. …

Calcium isotope analysis used to predict myeloma progression

The researchers tested a new approach to detecting bone loss in cancer patients by using calcium isotope analysis to predict whether myeloma patients are at risk for developing bone lesions, a hallmark of the disease. They believe they have a promising technique that could be used to chart the progression of multiple myeloma, a lethal disease that eventually impacts a patient’s bones. The method could help tailor therapies to protect bone better and also act as a way to monitor for possible disease progression or recurrence. “Multiple myeloma is a blood cancer that can cause painful and debilitating bone lesions,” said Gwyneth Gordon, an Associate Research Scientist in ASU’s School of Earth and Space Exploration, and co-lead author of the study…

U.S. cervical cancer rates higher than previously reported, especially among older women, African-American women

Previous research finds an age-standardized rate of about 12 cases of cervical cancer per 100,000 women in the United States, with the incidence reaching a peak at age 40-44 and then leveling off. However, these estimates included women who had hysterectomies in which the lower part of the uterus, the cervix, was removed. By excluding these women, who are no longer at risk of developing this cancer, from their analysis, the researchers calculated a rate of 18.6 cases of cervical cancer per 100,000 women. They found the incidence increased steadily with age and peaked at a higher rate and at an older age, specifically in women 65-69 years old…

ACP recommends against pelvic exam in asymptomatic, average risk, non-pregnant women

ACP’s new evidence-based clinical practice guideline, “Screening Pelvic Examination in Adult Women,” was published today in Annals of Internal Medicine, ACP’s flagship journal. ACP’s guideline is based on a systematic review of the published literature on human subjects in the English language from 1946 through January 2014. “Routine pelvic examination has not been shown to benefit asymptomatic, average risk, non-pregnant women. It rarely detects important disease and does not reduce mortality and is associated with discomfort for many women, false positive and negative examinations, and extra cost,” said Dr. …
